+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) 19yy <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) 19yy name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989

+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+ GNU LIBRARY GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1991 Free Software Foundation, Inc.
+ 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the library GPL. It is
+ numbered 2 because it goes with version 2 of the ordinary GPL.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Library General Public License, applies to some
+specially designated Free Software Foundation software, and to any
+other libraries whose authors decide to use it. You can use it for
+your libraries, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if
+you distribute copies of the library, or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link a program with the library, you must provide
+complete object files to the recipients so that they can relink them
+with the library, after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ Our method of protecting your rights has two steps: (1) copyright
+the library, and (2) offer you this license which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ Also, for each distributor's protection, we want to make certain
+that everyone understands that there is no warranty for this free
+library. If the library is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original
+version, so that any problems introduced by others will not reflect on
+the original authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that companies distributing free
+software will individually obtain patent licenses, thus in effect
+transforming the program into proprietary software. To prevent this,
+we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
+
+ Most GNU software, including some libraries, is covered by the ordinary
+GNU General Public License, which was designed for utility programs. This
+license, the GNU Library General Public License, applies to certain
+designated libraries. This license is quite different from the ordinary
+one; be sure to read it in full, and don't assume that anything in it is
+the same as in the ordinary license.
+
+ The reason we have a separate public license for some libraries is that
+they blur the distinction we usually make between modifying or adding to a
+program and simply using it. Linking a program with a library, without
+changing the library, is in some sense simply using the library, and is
+analogous to running a utility program or application program. However, in
+a textual and legal sense, the linked executable is a combined work, a
+derivative of the original library, and the ordinary General Public License
+treats it as such.
+
+ Because of this blurred distinction, using the ordinary General
+Public License for libraries did not effectively promote software
+sharing, because most developers did not use the libraries. We
+concluded that weaker conditions might promote sharing better.
+
+ However, unrestricted linking of non-free programs would deprive the
+users of those programs of all benefit from the free status of the
+libraries themselves. This Library General Public License is intended to
+permit developers of non-free programs to use free libraries, while
+preserving your freedom as a user of such programs to change the free
+libraries that are incorporated in them. (We have not seen how to achieve
+this as regards changes in header files, but we have achieved it as regards
+changes in the actual functions of the Library.) The hope is that this
+will lead to faster development of free libraries.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, while the latter only
+works together with the library.
+
+ Note that it is possible for a library to be covered by the ordinary
+General Public License rather than by this special one.
+
+ GNU LIBRARY GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library which
+contains a notice placed by the copyright holder or other authorized
+party saying it may be distributed under the terms of this Library
+General Public License (also called "this License"). Each licensee is
+addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+ 6. As an exception to the Sections above, you may also compile or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ c) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ d) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the source code distributed need not include anything that is normally
+distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Library General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ Appendix: How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the library's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This library is free software; you can redistribute it and/or
+ modify it under the terms of the GNU Library General Public
+ License as published by the Free Software Foundation; either
+ version 2 of the License, or (at your option) any later version.
+
+ This library is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+ Library General Public License for more details.
+
+ You should have received a copy of the GNU Library General Public
+ License along with this library; if not, write to the Free
+ Software Foundation, Inc., 59 Temple Place - Suite 330, Boston,
+ MA 02111-1307, USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the
+ library `Frob' (a library for tweaking knobs) written by James Random Hacker.
+

+
+ * tm-vax.h (ASM_OUTPUT_REG_POP): Use correct asm syntax for pop insn.

+ don't touch other insns they point at.
+
+ * expr.c (do_jump): Use invert_exp, not reverse_condition,

+Thu Dec 1 16:44:10 1988 Richard Stallman (rms at sugar-bombs.ai.mit.edu)
+

+ * i386.md (mulsi3): Don't use rtx_equal_p to compare regs.
+
+ * expr.c (move_by_pieces_1): Don't call change_address

+

+ because (1) they aren't supported and (2) they are never used.
+
+ * gnulib.c (__builtin_saveregs): If not sparc, define the symbol anyway
+ to avoid a warning in ranlib.
+
+Mon Nov 28 01:46:12 1988 Michael Tiemann (mdt at choctaw)

+
+ * sparc.md (various places): make sure that all patterns which store
+ can store using const0_rtx (i.e., make all operands to `st' %rx).
+
+ * output-sparc.c (various places): changed dispatches on SYMBOL_REF
+ to dispatches on CONSTANT_ADDRESS_P since we now recognize any CONST
+ (and not just SYMBOL_REFs). Don't recognize special case CONST for
+ output_block_move. Compiler doesn't have enough information to use
+ it.
+
+ * stmt.c (expand_fixup): If the control stack is nested within the
+ nesting stack, then no fixup is needed. Otherwise, compiler must
+ check for possible fixups between the current nesting stack and the
+ nesting stack that immediately contains the control stack.
+
+ * stmt.c (expand_function_start): functions which are nested use
+ DECL_CONTEXT. For these functions, test that their DECL_CONTEXT is

+ * sparc.md (movdi): Allow immediate args moved into general regs.
+

+ declarating, not defining. Change types to error_mark_node
+ in both the PARM_DECL and the list of types.
+
+ * dbxout.c (dbxout_type): It's not a bug if a RECORD_TYPE
+ has a typedef as its TYPE_NAME. That happens in C++.
+
+ * Make each `asm' with operands record its source file/line
+ with reg-notes. It doesn't work to emit a special note before the insn
+ because the insn can be moved by loop_optimize.
+ * stmt.c (expand_asm_operands): New args FILENAME, LINE.
+ Record them in the insn, in reg notes.
+ * c-typeck.c (c_expand_asm_operands): New args, passed along.

+
+ * reload.c (find_reloads_address): Reloading a constant address,
+ specify Pmode as the mode for push_reloads, in case of CONST_INT.
+
+ * expr.c (emit_push_insn): Fix calc. of space needed when PARTIAL > 0.
+ Both scalar case and BLKmode case needed fixing.
+
+ * sparc.md (load/store constant address):
+ Moving DF from mem to cpu regs, don't go via %f0.
+ Don't use std/ltd if alignment is wrong or uncertain.
+
+Sun Nov 27 10:34:53 1988 Michael Tiemann (mdt at yahi)
+
+ * reload.c (push_reload): Allow VOIDmode for INMODE, OUTMODE;
+ default the mode from the operand values.
+
+ * sparc.md: remove patterns which generate annulled branch insns.
+ They are correct, but those insns confuse GDB.
+
+ * tm-sparc.h (GO_IF_LEGITIMATE_ADDRESS):
+ Treat any constant address like a SYMBOL_REF.
+ * sparc.md: Check for CONSTANT_ADDRESS_P rather than SYMBOL_REF.
+
+ * sparc.md: Peepholes now accept SYMBOL_REF addresses.
+ The output routine can now split them properly even as delay insns.
+
+ * print-tree.c (dump): added entry for METHOD_TYPE and
+ METHOD_CALL_EXPR. Also added entry for WITH_CLEANUP_EXPR. Suggest
+ that we make first_rtl of WITH_CLEANUP_EXPR 2 instead of 1.
+
+Sun Nov 27 00:15:33 1988 Michael Tiemann (mdt at yahi)
+
+ * print-tree.c (dump): added entry for OP_IDENTIFIER.
+
+ * tree.c (build_op_identifier): new function. Needed because
+ `build_nt' expects an "e" node, but OP_IDENTIFIER is an "x" node.
+
+ * store_layout.c (layout_record): use DECL_FIELD_CONTEXT instead of
+ DECL_CONTEXT.
+
+ * tree.h (DECL_FIELD_CONTEXT): new macro. Points to the type that a
+ FIELD_DECL is a member of. For C, this is just DECL_CONTEXT.
+
+ * tree.c (build_method_type): typo used "==" to assign basetype to
+ TYPE_METHOD_BASETYPE with predictably poor results.
+
+Sat Nov 26 22:55:32 1988 Michael Tiemann (mdt at yahi)
+
+ * output-sparc.c (output_sized_memop): new function to output a load
+ or store insn based on the size of the operand loaded or stored.
+ (make_f0_contain_0): use info from condition codes to decide whether
+ the register %f0 needs to have 0 loaded from memory or not in order
+ to contain zero.
+ (gen_scc_insn): new function used by define_expands for
+ set-on-condition-code insns.
+ (output_delay_insn): now knows how to handle load and store
+ scheduling when the load or store operation takes two insns instead
+ of one. The rewrite is now understands is this:
+
+ sethi %hi(address),%g1 -> sethi %hi(address),%g1
+ ld/st [%g1+%lo(address)],%reg -> b target
+ b target -> ld/st [%g1+%lo(address)],%reg
+ nop -> ;; gone
+
+ * jump.c (reverse_condition): make this function publicly visible,
+ now needed in expr.c.
+
+ * output-sparc.c (reg_or_0_operand): new function, returns nonzero
+ if operand is const0_rtx or a register of specified mode.
+ (hardreg): deleted.
+
+ * expr.c, stmt.c: fixed random syntax errors.
+
+ * tree.c (build_method_type): now corresponds to defn in tree.def
+ expr.c (expand_call): removed code to get FUNCTION_TYPE from
+ METHOD_TYPE. This should probably be looked at harder.
+
+ * tree.def (METHOD_TYPE): Changed definition so that TREE_TYPE (m)
+ (where m is a METHOD_TYPE) is the type of the return value of the
+ method, not the FUNCTION_TYPE from which the METHOD_TYPE is derived.
+
+ * Makefile: Changed target of BINDIR from /usr/local to
+ /usr/local/bin.

+

+ (subst): Collapse nested SUBREGs even if SUBREG_WORDs are not 0.
+
+ * expr.c (bcc_gen_fctn, setcc_gen_fctn): new tables,
+ initialized in init_comparisons.
+ Used in expand_expr, do_jump, do_store_flag
+ instead of explicit construction of a jump.
+
+ * expr.c (save_noncopied_parts): New function.
+
+ * expr.c (expand_expr):
+ ARRAY_REF: Special case for array of constants.
+ WITH_CLEANUP_EXPR: Handle it.
+ INIT_EXPR: Case deleted.
+ MODIFY_EXPR: Use save_noncopied_parts.
+
+ * expr.c (expand_call): blkmode_parms_forced can be >0
+ even when no stack arg space otherwise needed.

+
+ * stmt.c (struct block): New elt. outer_cleanups.
+ (struct case): New elt. num_ranges.
+ (struct fixup): Changed meaning of cleanup_list_list.
+ Changes in expand_fixup, fixup_gotos.

+ This can cause the use of multiple insns with same output reg,
+ which can confuse cse.

+ No need to reset elements out of range of prev block's NEXT_QTY.
+ (reg_is_born, reg_is_set, wipe_dead_reg):

+ (cse_insn): Don't call find_reg_note if REG_NOTES is 0.
+
+ * cse.c (cse_insn): Store modified SET_SRC even if there's a REG_EQUIV.

+ (propagate_block): Don't call mark_{used,set}_regs for a stack-pop
+ since if it isn't dead it has no effect on any useful life data.
+ (mark_set_1): Return quickly if setting stack-ptr, and almost as

+ in integer case (they were for casting a pointer).
+

+
+ * parse.y: Add missing semicolons in actions.
+ (yylex): Don't use yylloc.
+
+Sun Jun 5 16:14:40 1988 Richard Stallman (rms at sugar-bombs.ai.mit.edu)

+ an equivalent value is needed. Equivalence must be good in that mode.
+ In addition, notice overlap with multiword register modes.
+ Simplify, knowing that registers have already been renumbered.
+ It was invalidating memory-goals too easily; setting a reg
+ only invalidates memory-goal if its address varies.
+ * reload.c, reload1.c, jump.c: Calls pass the new argument.

+ check HARD_REGNO_MODE_OK so we don't get fooled by an odd-even pair.
+ Spill entire need for new groups before spilling any solitary regs.
+ Reg already counted against max_nongroups can't become part of a group.
+ (new_spill_reg): Do bookkeeping associated with a new spill-reg.
+ (n_spills): This var is now static, no longer passed as arg
+ within the file.
+
+ (reload_reg_class_lower): Handle all group-reloads before solitaries.
+ (choose_reload_targets): therefore #if 0 the special code for
+ finding solitary registers that aren't suitable for groups.
+ But fix two bugs in it: braino deciding whether a reload
+ is looking for 1 register (not a group). Use CLASS_MAX_NREGS.
+ Also braino deciding whether a spill reg can be in a group.
+ Did not fix bug that it fails to test HARD_REGNO_MODE_OK,
+ so it might split up an even-odd pair.
+
+ * vax.md: Special patterns for 8 and 16-bit fields, to make
+ move-insns (like the ones for the 68k).
+
+ * tree.c (convert_to_integer): Pass truncation down thru COND_EXPR

+
+ * reload1.c (reload): Was counting insn_groups as total size of groups,

+ Don't allow nonexplicit constants in lprd, multiply or truncate insns.
+ Use reg_or_mem_operand for constraint in op1 of divide insns;
+ a constant there causes regclass to screw up.
+ Split alternative constraints on the bit-field insns to avoid

+ (use_variable): Emit USE for regs used in specified rtx.
+
+ * cse.c (fold_cc0): Stack-frame addresses are always nonzero.

+
+ * decl.c (poplevel): Undo previous change with #if 0.
+
+ * stmt.c: `struct nesting' now records the depth on the stack.

+
+ * decl.c (duplicate_decls): Ignore `inline' decl following definition.

+ * cccp.c (skip_if_group): For validate_else, pass BP (end of cmd name).
+ Don't call validate_else if do_else or do_endif will detect error.
+
+ * Bug: inline fcns can refer to the return reg with a strict_low_part
+ which confuses expand_inline_function. Fix is to change return reg
+ into inline_target *everywhere* except in or right after a call.
+ * integrate.c (copy_rtx_and_substitute): Delete special case for SET.
+ Replace return-value hard regs with INLINE_TARGET in all contexts.
+ (expand_inline_function): special handling for insn after a CALL_INSN
+ if it copies the function value out.
+ Allow notes and stack adjust insns to intervene
+ between the CALL_INSN and the value-copy.
+
+ * expr.c (emit_call_1): New name for gen_call_1.
+
+ * Bug: ({...}) insns were in wrong place for a subexpression
+ after a sequence point, as in x ? y : ({...}).
+ * tree.def: New tree-code RTL_EXPR holds a sequence.
+ * expr.c (expand_expr): Handle RTL_EXPR by emitting the sequence.
+ * stmt.c (expand_{start,end}_stmt_expr): Use emit_to_sequence

+
+ * parse.y (yylex): Handle syntax L"..." and L'...'

+
+ * parse.y: Define keyword `noalias'.
+ * parse.h: Define RID_NOALIAS.

+
+ * typecheck.c (shorten_compare): When data type determines the value,
+ eval the nonconstant arg anyway if it has side effects.
+ (build_conditional_expr): When merging `foo *' with `void *',
+ also allow `const void *'. Result type has merged set of qualifiers.
+ (qualify_type): Merge qualifiers of two types.
+
+ * decl.c (get_parm_types): Store any tags defined in parmlist
+ into `last_function_parm_types'.
+ (store_parm_decls): Add those tags into the current binding level.
+
+ * parse.y (parmlist, parmlist_or_identifier): Pass 0 to pushlevel;
+ no binding levels in C should be transparent to tags.
+
+ * 3b1 support:
+ * tm-3b1.h: New file.
+
+ * m68k.md: Add HPUX_ASM conditionals for shift-by-24-and-compare.
+ In one of the dbra patterns, a HPUX_ASM conditional was backwards.
+ (movhi) [SGS_3B1]: Define the LI... label as in MIT syntax.
+ (addsi3) [SGS]: Syntax for base-displacement differs from MOTOROLA.
+ (subsi3) [SGS]: likewise.
+ (tablejump) [ASM_OUTPUT_CASE_LABEL]: Use 6, not 2, as displacement.
+ This assumes ASM_OUTPUT_CASE_LABEL on 68k is used for a `swbeg'.
+
+ * final.c (final): Use ASM_OUTPUT_CASE_LABEL (if defined) to output
+ any CODE_LABEL followed by an ADDR_VEC or ADDR_DIFF_VEC.
+ It has 4 args; 4th is the insn which is the ADDR_VEC or ADDR_DIFF_VEC.

+ is FIRST_PARM_INSN, not FIRST_FUNCTION_INSN.
+
+ * tree.c (build_string): String contents must be saveable (for
+ inline fcn).
+
+ * cse.c (cse_insn): Don't forget to set dest_hash_code when dest
+ is a stack slot (and so its address is not being optimized).
+
+ * emit-rtl.c (restore_reg_data_1): reg_rtx_no must be 1+ largest REGNO.
+
+ * m68k.md (non-SImode bit-field insns): Change constraint to "o,d"
+ so a nonoffsetable memref is handled by reloading its address
+ but a register can still be handled.
+
+ * toplev.c (main): Execute OVERRIDE_OPTIONS, if it's defined.
+
+Sat Apr 2 00:55:21 1988 Richard Stallman (rms at wheaties.ai.mit.edu)
+
+ * expr.c (convert_move): Handle a SUBREG in direct truncation case.
+
+ * cse.c (lookup_for_remove): Don't test machine mode of registers:
+ Storing in (REG:SI 0) invalidates (REG:DF 0).
+
+ * decl.c (pushlevel): New arg, nonzero means this level is for
+ variables only, not for tags. All calls changed.
+ (lookup_tag): Even if THIS_LEVEL_ONLY, skip variables-only levels.
+ (pushtag): Define it in the first non-variables-only level.
+
+ * dbxout.c (dbxout_type): Undo Mar 29 change, in the DBX_NO_XREFS case.
+ So now each struct or union will contain only nameless cross-refs
+ to any others it uses. The prior change is still in effect when
+ DBX_NO_XREFS is not defined.
+
+ * Implement variable array bounds for parameters.
+ * decl.c (poplevel): Don't crash if DECL_NAME gives 0.
+ * typecheck.c (comptypes): A variable array bound matches anything.
+ * parse.y (parmlist): Call pushlevel, then pushdecl each parm as it
+ is parsed; then poplevel after using get_parm_types to extract the
+ results of the parmlist.
+ * decl.c (get_parm_types): New function; reverse the current decls,
+ put them in last_function_parms, and return a list of their types.
+ (grokparms): Arg is now an idlist or a typelist. Do nothing if latter.
+ (push_parm_decl): New function, like {start,finish}_decl combined
+ for a parm in a parmlist.
+
+ * dbxout.c (dbxout_symbol): Ignore sym if its DECL_RTL is 0.
+
+ * symout.c (symout_block_symbols): Ignore sym if type is error_mark.
+
+Fri Apr 1 11:41:21 1988 Richard Stallman (rms at wheaties.ai.mit.edu)

+ * expr.c (prepare_call_address): New function; given two rtx's
+ for function and context, copy the context to the right hard reg,
+ put the function address in the right place and return an rtx for it.
+ (gen_call_1): No longer do those things. Delete args CONTEXT, PROTECT.
+ (emit_library_call, expand_call): Call `prepare_call_address'.

+ * varasm.c (assemble_variable): Use ASM_FORMAT_PRIVATE_NAME
+ to make the name for a local static variable.

+
+ * tm-m68k.h, tm-ns32k.h (FIX_FRAME_POINTER_ADDRESS):
+ To refer to stack ptr, use stack_pointer_rtx, not a copy.
+
+ * tree.c (build_real_from_string): Function deleted.
+ * parse.y (yylex): Use build_real and atof.
+
+ * parse.y: Allow string concatenation in arg of asm.
+
+ * parse.y (yylex): Always allow `$' in ident, but warn if pedantic.
+ * tm-vms.h: Delete DOLLARS_IN_IDENTIFIERS (no longer tested).
+
+ * cccp.c (rescan, do_define, initialize_random_junk):
+ Always allow `$', but warn if pedantic.
+ (main): If -t, set `traditional'.
+ (collect_expansion): If `traditional', no special handling for quotes
+ and no whitespace added at end of macro definition.
+
+ * expr.c (compare, compare1): Last arg to compare_constants
+ must be a size in bits.

+Thu Mar 31 00:31:52 1988 Richard Stallman (rms at wheaties.ai.mit.edu)
+
+ * expmed.c (expand_mult, expand_divmod, extract_fixed_bit_field):
+ Reject function return register as target if may need to read it.
+ (Reading the return register in an inline function doesn't work.)
+
+ * decl.c (start_function): Delete extra arg to `error'.
+
+ * emit-rtl.c (last_parm_insn): Delete this unused var.
+
+ * make-cc1.com: New version from Kashtan.
+
+ * integrate.c (expand_inline_function): Always set up an INLINE_TARGET
+ for a function that returns a nonvoid nonBLK value.
+ Since `pushlevel' and `poplevel' are called, must also call
+ `expand_{start,end}_bindings' to make a pair of NOTEs.
+ Let them handle USEs at end of scope of formal parameter copies.
+
+ * integrate.c (expand_inline_function): In a new-style CALL_INSN,
+ don't change the result reg into INLINE_TARGET. Also,
+ generate a move insn after the call only if INLINE_TARGET is non-0.
+
+ * integrate.c (copy_decl_tree): Don't crash if DECL_RTL is 0.
+
+ * integrate.c (copy_for_inline): Don't treat `return' rtx's specially.
+
+ * stmt.c (expand_{start,end,emit}_delayed_expr):
+ New fns to handle ({...})'s in expressions output not where parsed

+ (reg_is_set): For reg that dies in this insn, mark it dead from now on
+ and post_mark it live after this insn only.
+
+ * combine.c (try_combine): Don't allow a call insn as I1 or I2.
+
+ * loop.c (count_loop_regs_set): Move CALL_INSN into a separate
+ clause. When finding regs that are function addresses, handle
+ both old and new format call insns.
+
+ * flow.c (insn_dead_p): A SET that contains a CALL can't be dead.
+ (volatile_refs_p): Any CALL constitutes a volatile ref.
+ (mark_used_regs): If setting a reg from a volatile ref,
+ treat it like setting a reg whose value will be used.
+
+ * expr.c (gen_call_1): New arg VALREG if nonzero means generate
+ a call_value insn which stores in VALREG.
+ (expand_call): Use `hard_function_value' to make the VALREG arg
+ unless expression has type `void'.
+
+ * expr.c (emit_library_call): New 2nd arg OUTMODE is mode of result.
+ (So can give gen_call_1 the proper value-register.)
+ All callers (here and optabs.c) pass this arg.
+
+ * cse.c (canon_hash): Consider all CALL rtx's volatile.
+
+ ** end of change in representation of call insns.
+
+ * stmt.c (expand_asm_operands): Replace complex lvalues with

+
+ * Version 1.19 released.
+

+ (scan_loop): If insn might trap, move only if loop always executes it.
+
+ * dbxout.c (dbxout_type): Never output a cross-ref for
+ a type whose definition is known. Sun dbx won't accept them.
+
+Mon Mar 28 12:34:46 1988 Richard Stallman (rms at wheaties.ai.mit.edu)
+
+ * tm-vms.h (TARGET_DEFAULT): Default is PCC alignment.

+
+ * typecheck.c (c_expand_return): Don't ignore return value
+ when its type is void.
+
+ * final.c (final): Forget the condition codes after an `asm'.
+
+ * typecheck.c (build_binary_op_nodefault): Warn about ptr < 0
+ even if not pedantic, but not if traditional.
+
+ * typecheck.c (convert_for_assignment): Don't warn about
+ pointers volatile * vs nonvolatile * if -fvolatile specified.
+
+ * decl.c (store_parm_decls): Among the old-style parm decls
+ there can legitiately be other decls! For example, if a parm
+ is declared `enum {foo, bar} x;', there are decls for `foo' and `bar'.
+ Don't let anything but a PARM_DECL match a parm name;
+ pass all the other decls through into the lexical context.
+
+ * jump.c (jump_optimize): When deleting stack adjusts before a
+ jump-to-return, don't be fooled by intervening NOTEs.
+
+ * tm-sequent.h (PRINT_OPERAND): Output (MEM (MEM (REG))) properly.
+ * output-ns32k.c (print_operand_address): Output (MEM (REG))
+ properly; output stack-pointer as `tos'.
+
+ * flow.c (find_use_as_address): Reject uses within operand 0
+ of a ZERO_EXTRACT or SIGN_EXTRACT reference. It's hard to reload
+ an autoincrement inside these because they can refer to multiple bytes.
+
+ * reload.c (find_reloads): `o' in constraint means any memref
+ (except auto-increment) is acceptable with reloading.
+ Braino: Clear BADOP, not BAD.
+
+ * reload.c (push_reloads): Use rtx_equal_p (via macro MATCHES)
+ when considering reuse of an old reload. Otherwise equal values
+ may get reloaded into different registers, and two MEMs that
+ originally matched may fail to match once reloaded.
+
+ * m68k.md (sign_extract and zero_extract insns):
+ If operand 0 is QI or HImode, don't allow register--only `o'
+ (except in some bftst patterns where bitpos is < 8).

+ skip elts that are marked with `equivalence_only'.
+
+ * decl.c (duplicate_decls): Don't call `layout_type'
+ if the type is `error_mark_node'.
+
+ * decl.c (implicitly_declare): If decl will be file-scope,

+
+Sat Mar 26 15:48:50 1988 Richard Stallman (rms at wheaties.ai.mit.edu)
+
+ * flow.c (insn_dead_p, mark_used_regs): Storing a reg via a

+ to the name of this function.
+ * tm-vms.h (MAYBE_VMS_FUNCTION_PROLOGUE): Use current_function_name.
+

+
+ * expr.c (expand_call): Eval function before copying args to hard regs.
+
+ * tree.c (make_node, copy_node): Don't get length of a REAL_CST

+ * tm-vax.h: Define STRUCTURE_SIZE_BOUNDARY since Unix CC seems to.
+

+ to indicate which of the alternatives this insn matches.
+
+ * typecheck.c (commontype): long int vs unsigned int

+
+ * emit-rtl.c, tree.c: include local version of varargs.h.

+ * flow.c (mark_used_regs): Ignore STRICT_LOW_PART, so that
+ an insn that sets STRICT_LOW_PART (and its source values) may be dead.
+ (propagate_block): Always pass 1 for strict_low_ok to insn_dead_p.
+
+ * optabs.c (emit_unop_insn): Don't make a REG_RETVAL note.
+ Change above deletes dead STRICT_LOW_PART stores without one.
+
+ * optabs.c (expand_binop, expand_unop): If the library address
+ is to be put in a pseudoreg, do it here, and make the REG_RETVAL
+ note point after that.
+
+ * expr.c (emit_library_call): Never defer stack-pops.
+ Deletion of the library call by flow.c loses if they are deferred.
+
+ * cse.c (cse_insn): Handling of 68k's zero-extend was broken:
+ it made the actual source and the REG_EQUAL source equivalent.
+ * If dest is a STRICT_LOW_PART, ignore the actual source and use
+ the REG_EQUAL source in its place. src_eqv's mode may be different
+ from src's, so use proper mode in lookups or inserts for src_eqv.
+ * Don't forget to set src_eqv_elt if src_eqv already has an elt.
+ * On use_related_value for src_eqv, use src_eqv_elt.
+
+ * toplev.c (main_input_filename): Name of file mentioned in first
+ #-line in the input.
+ (compile_file): Pass it to dbxout_init as 2nd arg.

+ (emit_push_insn): Use move_block_to_reg when PARTIAL > 0.
+ Also, don't subtract USED from SIZE twice.
+ Use plus_constant to add ARGS_SO_FAR so can use indexing on stack ptr.
+
+ * varasm.c (assemble_integer_zero): Use rtx 0, not tree 0,
+ to go with prev change in ASM_OUTPUT_INT.

+
+ * parse.y: Define YYDEBUG.
+
+ * rtl.c (rtx_unstable_p): New function, same as old rtx_varies_p.
+ * explow.c (stabilize): Use rtx_unstable_p.
+ * rtl.c (rtx_varies_p): Ignore `unchanging' (undoing previous change
+ in this function) because `unchanging' doesn't enable cse to compare
+ the value with any particular constant value.
+ * rtl.c (insn_store_addr_varies_p): Delete, since not used.
+
+ * hard-reg-set.h (COPY_HARD_REG_SET, etc.) non-scalar case:
+ Rename and rearrange temp variables to avoid name conflicts with args.
+
+ * regclass.c (reg_class_record): Don't smash class to GENERAL_REGS
+ and don't exit prematurely, when `r' or `g' is seen. Must merge
+ GENERAL_REGS with previously determined desired class.

+ * expr.c (expand_call) [no PUSH_ROUNDING]: When pushing the arg
+ block, try to reuse some of the pending_stack_adjust.
+
+ * cse.c: qty_const can now hold values (PLUS frame_pointer integer).
+ Effect is that storing into a structure doesn't invalidate
+ mem refs to scalar stack variables via addresses in registers.
+ (insert): Load such values into qty_const, like true constants.
+ (fold_rtx): Ignore qty_const if it isn't really a constant.
+
+ * expr.c (expand_expr) VAR_DECL: Copy DECL_RTL before calling
+ change_address, so it isn't permanently clobbered.

+ * stmt.c (fixup_var_refs_1): Make sure the stack slot address
+ is valid by calling fixup_stack_1 each time it is substituted.
+
+ * stmt.c (fixup_stack_1): Return the altered rtx.
+ If it's a MEM in the stack, return a copy of it.
+
+ * stmt.c (fixup_stack_slots): #if 0.
+ * stmt.c (expand_finish_function): Don't call fixup_stack_slots
+ because fixup_stack_1 is called elsewhere when necessary.
+
+ * reload.c (find_reloads_address): New arg is location of the MEM
+ whose address is being reloaded. So we copy the MEM if it
+ is one that can be shared. New arg 0 means no need to copy the MEM.
+ All callers pass the new arg.
+
+ * stmt.c (assign_parms): Determine parm stack-size from
+ the DECL_ARG_TYPE, not from the TREE_TYPE.
+ Else loses when parm is declared `float' but passed as `double'.
+
+ * emit-rtl.c (make_safe_from): Constants are already safe.
+ Use proper machine mode for temp reg when needed.

+
+ * expr.c (emit_push_insn): Don't pass wrong type to plus_constant
+ (case where there is no PUSH_ROUNDING).
+
+ * expr.c (expand_call): Round partial[i] down to multiple of

+ Compute these sizes just once and keep them in vector `arg_size'.
+ * expr.c (emit_push_insn): Handle `partial' uniformly, in accord
+ with this new convention for how it affects the stack size.
+ * stmt.c (assign_parms): Round NREGS down to PARM_BOUNDARY likewise.
+
+ * obstack.h (obstack_free macro) [Not __GNUC__ but __STDC__]:
+ Don't cast result of (obstack_free) to (int); just ignore it.
+
+ * reload.c (find_reloads): Initialize operand_reloadnum.
+
+ * optabs.c (emit_unop_insn): New argument CODE, used to make
+ a REG_EQUAL note from operand OP0 if more than one insn results.

+ * expr.c (convert_move): Pass CODE arg to emit_unop_insn.
+ * flow.c (propagate_block): Use insn_dead_p to decide whether
+ to handle a REG_RETVAL note by skipping some insns.

+ Handle case where REG_RETVAL points at an insn that's deleted.
+ * flow.c (insn_dead_p): New operand STRICT_LOW_OK says an insn
+ that sets STRICT_LOW_PART may be considered dead.
+
+ * expr.c (expand_expr): Once again canonicalize X-C to X+(-C).
+ Change on March 1 made it stop doing this.
+
+Wed Mar 9 01:25:35 1988 Richard Stallman (rms at wheaties.ai.mit.edu)
+
+ * loop.c (move_movables): Don't always mark the moved reg

+
+ * expr.c (move_by_pieces_1): Finish last change.
+
+ * stmt.c (assign_parms): Update stack_args_size properly.

+ * cse.c (insert): Build the related_value lists in the opposite order
+ so that the oldest element in the chain is the one that follows
+ the most basic element.
+

+ a mode we want.
+
+ * toplev.c (rest_of_compilation): Fix typo setting TREE_ASM_WRITTEN.
+
+Tue Mar 8 13:18:37 1988 Richard Stallman (rms at wheaties.ai.mit.edu)
+
+ * cse'ing of library calls.
+
+ * expr.h: type `optab' is now a ptr to a struct.
+ The old contents are now the `handlers' element.
+ The `code' element gives the RTL code for the kind of expression

+ In that case, for non-group reloads, prefer a reg that can't be in
+ group, or else one that has only one available neighbor.
+
+ * reload1.c (reload): Find separately the max need for each class
+ for single registers, groups of registers, and single registers

+ is needed for input reloads as well as output, since a strict_low_part
+ operand is normally a read-write operand.
+
+ * reload1.c (reload): The mode a reload needs is the wider of
+ the input and output modes--just as it is in choose_reload_targets.
+

+ when one of them would be affected by PUSH_ROUNDING.
+ Instead, make all the space and then copy.
+ * expr.c (expand_call): Don't apply PUSH_ROUNDING if BLKmode.
+
+ * Allow `asm' with operands to be marked volatile.
+ * cse.c (canon_hash): Don't record ASM_OPERANDS that has `volatil'.

+ * stmt.c (expand_asm_operands): New arg VOL; mark ASM_OPERANDS as vol.
+ * typecheck.c (c_expand_asm_operands): New arg VOL.

+ * cse.c (canon_hash): Hash string operands by contents, not address.
+ * cse.c (exp_equiv_p): Compare string operands with strcmp.
+ * rtl.c (rtx_equal_p): Compare string operands with strcmp.
+
+ * decl.c (init_decl_processing): Once sizetype is set,
+ correct the type of the sizes of types already made.
+

+
+ * reload.c (find_reloads): Now that `asm' is limited to
+ MAX_RECOG_OPERANDS, eliminate dynamic allocation of `constraints'
+ and `constraints1', and go back to `recog_operand' instead of
+ `operands'.
+
+ * typecheck.c (c_expand_asm_operands): New fn to handle `asm' for C.
+ Calls expand_asm_operands, and handles output operands that
+ the other function cannot handle.
+
+ * parse.y: Call that function.
+
+ * stmt.c (expand_asm_operands): Error if too many operands.
+ #include insn-config.h to get MAX_RECOG_OPERANDS.
+
+ * expr.c (expand_assignment): Use store_field to handle
+ structure fields and array elements.
+
+ * output-m68k.c (output_move_double): PUSHOP and POPOP were swapped.
+ Handle insns that push an sp-relative address onto sp;
+ these can arise with -fomit-frame-pointer.
+ BUG? Do unoffsetable mem refs using sp and fp lose?
+
+ * m68k.md (movdi,movdf): Allow unoffsetable mem refs
+ only if the other operand is a register.
+
+ * m68k.md (zero_extendqisi2): SGS conditionals deleted.
+ Supposedly the MOTOROLA syntax works for those addresses.
+
+ * typecheck.c (default_conversion):
+ If flag_traditional, preserve unsignedness when promoting ints,
+ and promote float to double.
+
+ * typecheck.c (build_binary_op_nodefault):
+ Allow comparisons between pointers and ints.
+ If not -traditional, warn about them.
+
+Mon Jan 25 02:11:18 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
+
+ * expmed.c ({extract,store}_split_bit_field):
+ Functions {extract,store}_split_reg_bit_field now work for memory
+ also, and therefore are renamed.
+ * ({extract,store}_fixed_bit_field): Call those fns when a field
+ is split across two words.
+ Also, preserve the `volatil' bit on memory refs.
+
+ * output-m68k.c (output_move_double): Handle nonoffsetable mem refs.
+ * m68k.md: Relax constraints on movdi, movdf.
+
+ * decl.c (init_decl_processing): Define `int' and `char' first.
+ Set `sizetype' explicitly.
+

+ doesn't have VAR as its src or dest.
+
+ * varasm.c: Don't include c-tree.h.
+
+ * decl.c (build_struct): Split this function into three:
+ `xref_tag', `start_struct' and `finish_struct'.
+ `xref_tag' subsumes `xref_enum'.
+
+ * parse.y (structsp): When parsing `struct foo {...}', define the tag
+ as a cross-ref before parsing the components. Use the three new fns.
+
+ * regclass.c (regclass): Recognize new-format ASM_OPERANDS insns
+ with `asm_noperands', and scan their operands as usual.
+
+ * cse.c: In numerous functions such as canon_hash, rtx_cost, etc.
+ that do tree-walk on rtx, handle vectors of subexpressions.
+
+ * loop.c (invariant_p): Likewise.
+
+ * jump.c (delete_insn): Two bugs:
+ If insn already deleted, return the first following nondeleted.
+ Deleting a jump's label can delete NEXT. Make sure return value
+ is always the first insn following INSN and not yet deleted.
+
+Sun Jan 24 02:27:49 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
+
+ * rtl.def (ASM_OPERANDS): Change the rtl expression of an
+ `asm' with operands so it looks like this for one output operand:
+ (set OUTPUT (asm_operands:OUTPUTMODE INSNSTRING OUTPUTCONSTRAINT
+ 0 INPUTS INPUTCONSTRAINTS)).
+ and like this for multiple outputs:
+ (PARALLEL [
+ (set OUTPUT0 (asm_operands:OUTPUTMODE INSNSTRING OUTPUTCONSTRAINT
+ 0 INPUTS INPUTCONSTRAINTS)).
+ (set OUTPUT1 (asm_operands:OUTPUTMODE1 INSNSTRING OUTPUTCONSTRAINT1
+ 1 INPUTS INPUTCONSTRAINTS))])
+
+ * parse.y: Change parsing of `asm' to distinguish input and output
+ operands. Separate them with colon; separate the string with colon.
+
+ * stmt.c (expand_asm_operands): Receive inputs and outputs separately.
+ Generate the new rtl format.
+
+ * recog.c (asm_noperands, decode_asm_operands): New fns
+ for extracting the operands and constraints from these insns.
+
+ * final.c (final): Recognize and output the new rtl format
+ using those new functions.
+
+ * reload.c (find_reloads): Recognize and get constraints
+ from the new rtl format using those new functions.
+ New variable `operand_modes' holds the machine modes of the
+ operands, obtained one way for ASM_OPERANDS insns and another
+ for other insns.
+
+ * rtl.c (note_stores): Calling convention
+ is changed: the first arg FUNCTION now receives as its 2nd arg
+ 1 if clobbering, 0 if setting. Used to be the CLOBBER or SET rtx.
+
+ * local-alloc.c (reg_is_set): This fn is called from note_stores;
+ change its arguments.
+
+ * tm-m68k.h (FIXUP_FRAME_POINTER_ADDRESSES):
+ Use frame_pointer_rtx to recognize intended frame-pointer refs
+ and not recognize pseudo-regs that were allocated to the frame
+ pointer register.
+
+ * emit-rtl.c: All refs to frame pointer use a single rtx, in
+ frame_pointer_rtx. Likewise arg_pointer_rtx for the arg pointer.
+ If they are the same register, these are the same rtx.
+ Initialize them in init_emit.
+ * rtl.h: Declare these vars.
+
+ * stmt.c (assign_parms, assign_stack_local): Use those rtx's.
+
+Sat Jan 23 00:32:10 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
+
+ * reload.c (find_reloads): Don't combine_reloads if `&' constraint
+ was used.
+
+ * parse.y: Parse `asm' with operands.
+ * stmt.c (expand_asm_params): New fn: generate an ASM_OPERANDS for
+ `asm' with operands.
+ * final.c (final): Output an ASM_OPERANDS insn-body.
+ * regclass.c (regclass): Ignore ASM_OPERANDS, like ASM_INPUT.
+
+ * reload.c (find_reloads): Handle reloading of ASM_OPERANDS.
+ The number of operands can no longer be bounded.
+ For example we can't always put the operands in recog_operands.
+
+ New locals OPERANDS and OPERAND_LOCS point to alloca'd vectors of
+ operands and their locations. New locals CONSTRAINTS and CONSTRAINTS1
+ hold alloca'd vectors of constraints.
+
+ Unfortunately this isn't enough; every vector with length
+ MAX_RECOG_OPERANDS needs to be dynamically allocated.
+ Would this be too slow? For now, a cheap "solution" is to delete
+ any insn that has too many operands.
+
+ * rtl.def: Delete VOLATILE, UNCHANGING and UNDESCRIBED.
+ Add ASM_OPERANDS.
+
+ * regclass.c (reg_class_record): Delete ref to UNCHANGING.
+ * loop.c (invariant_p):
+ * rtl.c (rtx_varies_p):
+
+ * cccp.c: Define __VERSION__.
+
+ * decl.c (shadow_tag): TYPE_NAME doesn't work to get the tag-name
+ of a struct, so use new function lookup_tag_reverse.
+ * decl.c (lookup_tag_reverse): Given a type, return its tag name.
+
+ * symout.c (symout_source_file): Output one `struct source'.
+ * symout.c (symout_lines): Output all of them, and the sourcevector.
+ * gdbfiles.h: New file for communication between final.c and symout.c.
+
+ * final.c (output_source_line): New arg WRITE_SYMBOLS says write
+ new GDB-format linenumber info. Assigns a filenum to each source
+ file name and keeps track of the correspondence.
+
+ * cccp.c (do_include): Output the -M info after searching the dirs;
+ include the actual dir name. Don't generate "./" for current dir.
+
+Fri Jan 22 04:10:10 1988 Richard Stallman (rms at frosted-flakes)
+
+ * tm-news800.h: Delete override of INDIRECTABLE_1_ADDRESS.
+ Output is faster if it doesn't use 32-bit displacements.
+
+ * reload.c (combine_reloads): New function.
+ If possible, find an input reload
+ and an output reload that can be turned into one input-output reload.
+ The old output-reload is marked as inoperative: reload_out
+ and reload_in both zero. This is called from find_reloads.
+
+ * reload1.c (reload, choose_reload_targets): Ignore inoperative
+ reloads.
+
+ * Print warnings for variables that could be clobbered by `longjmp'.
+ * expr.c (expand_call): Generate a NOTE_INSN_SETJMP whenever
+ `setjmp' or `_setjmp' is called.
+ * flow.c (propagate_block): When NOTE_INSN_SETJMP is seen,
+ record the live regs in `regs_live_at_setjmp'.
+ * stmt.c (uninitialized_vars_warning): Warn about vars that have regs
+ that are set more than once and are marked in `regs_live_at_setjmp'.
+ Works through function `regno_clobbered_by_longjmp'.
+ * rtl.h: Define NOTE_INSN_SETJMP.
+
+ * genrecog.c (try_merge_2): When enforce_modes, keep all the
+ alternatives segregated by modes and keep the modes in numerical order.
+ * genrecog.c (write_tree): Make conditions for switch-on-modes
+ know what difference enforce_mode makes.
+
+Thu Jan 21 00:12:35 1988 Richard Stallman (rms at frosted-flakes)
+
+ * tm-ns32k.h: Use Stein's definitions of PRINT_OPERAND{,_ADDRESS};
+ move the Sequent definitions info tm-sequent.h.
+ Handle %$ in both old and new PRINT_OPERAND.
+ Define CPP_PREDEFINES.
+
+ * ns32k.md: Merge some features from Jan Stein's port:
+ strict_low_part insns, smart output of booleans with small
+ constant args, acbd insns generalized for other increments.
+ Use %$ wherever there is an explicit immediate.
+ Fix shortcomings of adjsp insns: use adjspd in general,
+ and use adjspb in all the cases that allow it.
+ Don't bother explicitly clearing CC_REVERSED.
+ For tstsf/tstdf, output the floating-zero constants
+ using {f,d}const0_rtx.
+
+ A problem still remains, which is that the Sequent and the
+ other ns32k assembler syntax require different
+
+ * typecheck.c (unary_complex_value): Use correct datatype for
+ compound-exprs.
+
+ * gen*.c (main): Use obstack_init instead of obstack_begin.
+
+ * vax.md: define_peephole for andl3 x,y,z; extzv z,....,z
+
+ * m68k.md (tstsi): Use cmpw instead of cmpl to test addr reg.
+
+ * tm-m68k.h: Bugs for 68000 when frame size is over 64k.
+ For FUNCTION_PROLOGUE, just subtract from sp instead of fp.
+ For FUNCTION_EPILOGUE, must put the size into a0 and then
+ all insns must be indexed by a0. And do this even on 68020.
+
+ * tm-isi68.h: Similar changes.
+ * tm-news800.h, tm-hp9k320.h: Similar changes.
+
+Wed Jan 20 04:38:21 1988 Richard Stallman (rms at frosted-flakes)
+
+ * cccp.c (error_with_line): New function.
+ Use it to report the "unterminated whatever" errors.
+
+ * typecheck.c (build_unary_op): Recursive call had missing arg.
+
+ * m68k.md (movhi): If MOTOROLA, the insn that fetches from a
+ case-dispatch table now defines the LI label as .+2.
+ * tm-news800.el, tm-hp9k320.h (PRINT_OPERAND_ADDRESS):
+ Don't subtract 2 when outputting the address in that insn.

+
+ * final.c (output_asm_insn): If %LETTER with no digits,
+ pass null pointer as the operand.
+
+ * output-m68k.c (singlemove_string): Get rid of %e.
+
+ * stmt.c (fixup_memory_subreg): Convert (SUBREG (MEM a)) to (MEM a').
+ * stmt.c (fixup_var_ref_1): Use that fn for operands of
+ SIGN_EXTRACT and ZERO_EXTRACT, since (SUBREG:SI (REG:QI...))
+ could have turned into (SUBREG:SI (MEM:QI...)), which is unsafe.
+
+ * rtl.c (debug_rtx): Print an rtx on stderr, for debugging.
+
+Sun Jan 17 04:37:20 1988 Richard Stallman (rms at frosted-flakes)
+
+ * gcc.c: options -M* treated like -M.
+
+ * stmt.c (pushcase): Do nothing if the case index has error_mark type.
+
+ * expr.c (expand_increment): Don't use queue for post-inc on memory
+ if the add insn requires register args. (Better code for RISCs.)
+
+Sat Jan 16 02:10:22 1988 Richard Stallman (rms at frosted-flakes)
+
+ * ns32k.md: Change register_operand to general_operand.
+ * ns32k.md (udivmoddisi4): Use match_dup where required.
+ Comment it out because it can't accept two independent output args.
+
+Fri Jan 15 00:02:35 1988 Richard Stallman (rms at frosted-flakes)
+
+ * toplev.c: Include sys/time.h only for BSD. For USG, use time.h.
+ This is correct for HPUX; don't know about others.
+
+ * gcc.c (execute): Eliminate `union wait'. Make `status' an int.
+ * gcc.c (execute) [USG]: Use fork instead of vfork.
+
+ * final.c (output_source_line): Use ASM_OUTPUT_SOURCE_{FILENAME,LINE}

+ * tm-hp9k320.h: Define ASM_OUTPUT_SOURCE_{FILENAME,LINE}.
+
+ * m68k.md: Rename `hpux' conditionals to `HPUX_ASM'.
+ * m68k.md: Reverse `fcmp' args if HPUX_ASM.

+ * symout.c (symout_init): Save filename in symfile_name for err msg.
+
+ * gen*.c: Return 1 if ferror (stdout)--in case disk is full.
+
+ * local-alloc.c (block_alloc): Don't crash if 1st rtx
+ in a PARALLEL is not a SET.
+
+ * tm-m68k.h, tm-news800.h (PRINT_OPERAND). Eliminate code `%e'.
+ * m68k.md: Change `%e' to `e' everywhere.
+ * tm-hpux.h (ASM_OUTPUT_OPCODE): Output `move' as `mov'.
+
+ * tm-m68k.h, tm-news800.h, tm-hpux.h (PRINT_OPERAND):

+ * m68k.md (insns that use andi to ccr): Use `%!' to avoid

+ store in it the insn that established the value 0.
+
+ * vax.md (movsi): When checking a REG_WAS_0 note,
+ verify that the insn it points to hasn't been deleted or made a NOTE.
+
+Thu Jan 14 00:01:35 1988 Richard Stallman (rms at frosted-flakes)
+
+ * toplev.c: Eliminate error_with_line and warning_with_line.
+ * parse.y, decl.c: Change remaining calls to those two.
+
+ * tree.c (get_unwidened, get_narrower): To see if a COMPONENT_REF
+ is unsigned, look at the FIELD_DECL, not at the COMPONENT_REF.
+
+ * rtl.c (print_rtx): Print /v for the `volatil' bit.
+ * expr.c (expand_assignment expand_expr): If handling a COMPONENT_REF,
+ note whether it is volatile.
+
+ * fold-const.c (fold): a call to split_tree missed an argument.
+
+ * flow.c (volatile_refs_p): Scan an rtx for volatile mem refs.
+ * flow.c (life_analysis): Record in INSN_VOLATILE which insns
+ have any volatile mem refs.

+ this is the last time scanning.
+ * flow.c (propagate_block): Don't delete insns with volatile mem refs.
+
+ * flow.c: Remove all refs to `obey_regdecls'.
+ Calling this with -noreg just doesn't help -W.

+
+ * decl.c (finish_decl): Error if auto var's size isn't known.

+
+ * decl.c (grokfield): Don't set DECL_ALIGN here.
+
+ * stor-layout.c (layout_decl): Don't promote the type of a bit-field.
+ Use TREE_PACKED to distinguish a bit-field.
+ Don't check the width because build_struct did that.
+
+ * m68k.md (cmpm): Reject if either operand (address) is a constant.
+
+Tue Jan 12 15:11:20 1988 Richard Stallman (rms at frosted-flakes)
+
+ * cse.c (canon_reg): Never replace ANY hard reg from reg_rtx
+ because that could alter the machine mode.

+
+ * reload1.c (reload): basic_block_needs (new vector) gets 1
+ for each basic block that needs a reload.
+ * reload1.c (spill_hard_reg): Don't spill pseudos that are
+ confined to a basic block which has no need for any reloads.
+ * reload1.c (reload): Each cycle that any element of basic_block_needs
+ changes from 0 to 1, must re-spill all previously spilled regs.
+
+ * regclass.c (record_address_regs):
+ Skip the charging of ICOST if it is 0.
+
+ * flags.h, toplev.c: New flag -fvolatile.
+ * typecheck.c (build_indirect_ref): If flag_volatile,
+ every INDIRECT_REF is marked with TREE_THIS_VOLATILE.
+
+ * fold-const.c (fold): Test in TRUTH_NOT_EXPR case was backward.
+ Also result type is always `int'.
+
+Sat Jan 9 04:16:11 1988 Richard Stallman (rms at rice-krispies)
+
+ * flags.h (flag_traditional): New flag.
+ * toplev.c: recognize -ftraditional and -traditional.
+ * parse.y (yylex): If flag_traditional, don't recognize
+ `signed', `const' or `volatile'.
+
+ * decl.c (pushdecl): If flag_traditional, any extern decl
+ takes effect at top level.
+
+ * tree.c (lvalue_or_else): New 2nd arg for use in error message.
+ * typecheck.c: All callers pass 2nd arg.
+
+ * global-alloc.c: allocno_preferred_reg can specify a preferred
+ hard reg for each allocno. If so, try it first (new call to find_reg).
+
+ * global-alloc.c (find_reg): New arg PREFREG specifies reg to try
+ first.
+
+ * decl.c (build_struct): if :0 bit field at the end, round the
+ structure size to multiple of EMPTY_FIELD_BOUNDARY.
+
+ * cse.c (make_regs_eqv): Was testing for reg_next_eqv[lastr] == 0
+ and should be == -1.
+
+ * reload1.c (reload_as_needed): Fix invalid optimization deleting
+ the previous store into a pseudo-reg that feeds an input-reload.
+ It is not safe because a later insn may look in the pseudo's stack
+ slot for the value. Delete the store only if we can eliminate the
+ pseudo entirely or if the current insn stores a new value there.
+ Also verify that reload_in[j] is a REG.
+
+ * reload1.c (reload_as_needed): When doing an input reload from a
+ pseudo that was stored by the previous insn (not as a reload),
+ redirect the previous insn into the reload register, if this lets
+ us eliminate the pseudo entirely.
+
+ * reload1.c (reload_as_needed): In both of the above cases, it's
+ impossible to prevent a stack slot since one was already assigned,
+ so don't alter reg_n_refs. Instead, set reg_renumber to record
+ that this pseudo did get a hard reg.
+
+ * stmt.c: Set `volatil' in pseudo-regs for the user's variables.
+
+ * jump.c (delete_insn): Do nothing if insn already deleted.
+
+ * tm-sun{2,3}.h: #define STRUCTURE_SIZE_BOUNDARY 2
+ for compatibility with Sun PCC. Note that 4.3 vax PCC
+ does not want this.
+
+ * fold-const.c: Replace truncate_unsigned with force_fit_type
+ which truncates unsigned types and sign-extends signed types.
+
+ * expr.c (do_jump): emit_queue before outputting the jump insns
+ that use the comparison.
+
+ * stmt.c: Error message for any goto that jumps into a
+ binding contour that restores a stack level.
+
+ TREE_PACKED (label) means label was defined inside
+ such a binding contour that is now exited. Using such a label
+ is an error.
+
+ TREE_ADDRESSABLE (label) means label was used from a place
+ outside all such binding contours. If this is 1 when
+ TREE_PACKED is set to 1, it is an error.
+
+ Any other invalid goto must have a fixup. fixup_gotos detects
+ such invalid gotos. fixup_gotos takes a second arg, which
+ is the first insn of the contour now being exited.
+
+ * GNU C version 1.17.

+ * m68k.md (andsi3): Don't allow sp as ourput to avoid reload
+ inefficiency.
+
+ * calls.c (struct arg_data): Delete field STORED; add fields
+ PASS_ON_STACK and SAVE_AREA.
+ (prepare_call_address): Static chain value can't have QUEUED.
+ (expand_call): Rework to support additional calling sequence options.
+
+ Major changes include:
+ Call FUNCTION_ARG_PASS_BY_REFERENCE to determine whether an
+ object should be passed by invisible reference.
+ Handle arguments passed both on stack and in a register; this can be
+ used to allow arguments that are hard to compute directly into
+ registers to be passed.
+ Support option (ACCUMULATE_OUTGOING_ARGS) where the largest amount
+ of stack for outgoing arguments is computer and pushed during the
+ function prologue. Stack space usage is tracked and any location
+ that would need to be reused will be saved and restored.
+ If preallocating arg block, compute address where each arg will be
+ placed and pass it as target to expand_expr.
+
+ Other changes:
+ Use virtual regs to see if structure value address isn't stable.
+ If inlined, return TARGET if TARGET and TEMP are equivalent.
+ UNNAMED_ARGS_IN_REGISTERS is redundant with the NAMED parameter to
+ FUNCTION_ARG and has been deleted.
+ Use virtual_outgoing_stack_rtx instead of FIRST_PARM_CALLER_OFFSET.
+ Use locate_and_pad_parm to compute any needed padding for argument.
+ If REG_PARM_STACK_SPACE is defined, allocate backing stack locations
+ for args passed in registers; these are not included in the length
+ of stack space required unless OUTGOING_REG_PARM_STACK_SPACE is also
+ defined.
+ When precomputing register parameters, can stop computation when we
+ obtain any rtx, not necessarily a register.
+ No longer need code to protect data written below bottom of stack;
+ this is taken care of by preexpanding calls in argument.
+ target_for_arg no longer needed; its function is performed by
+ store_one_arg.
+ Always copy function return result to our target since they cannot
+ possibly be the same.
+ (target_for_arg): No longer used.
+ (store_one_arg): Save and restore in-use argument list location.
+ Support args passed both in register and on stack.
+ No need for explicit code for preallocated area; now pass location
+ as target to expand_expr; only copy if result in different place.
+ Put sequence point after expanding one value.
+
+ * cse.c (struct write_data): Add bit to indicate stack pointer changed.
+ (canon_hash): Allow recording of stack pointer.
+ (cse_insn): Indicate stack pointer invalidated by subroutine calls.
+ Pass stack push and pop operations to note_mem_written.
+ Process stack pointer assignment as normal operation.
+ Finish change of April 7th that excludes ap and fp from being marked
+ as clobbered by calls. Also exclude sp; if it is clobbered by a
+ call, an explicit CLOBBER will be written.
+ (note_mem_written): Look for adjustment of stack pointer.
+ (invalidate_from_clobbers): Invalidate stack pointer, if required.
+
+ * emit-rtl.c (gen_inline_header_rtx): Add field for outgoing args size.
+ (copy_rtx_if_shared): Check for any virtual register instead of frame
+ or argument pointer.
+ (init_emit): Start normal pseudos after virtual pseudos.
+ Copy the unique virtual regs into regno_reg_rtx.
+ (init_emit_once): Incoming and outgoing static chain can be the same;
+ inlining of nested functions won't need the distinction.
+ Create unique copies of virtual registers.
+
+ * explow.c (memory_address): Don't worry about refs to fp or ap;
+ force_reg knows how to handle them correctly.
+ (fix_lexical_addr): Moved to function.c
+ (adjust_stack, anti_adjust_stack): Do nothing for adjustment of zero.
+ (allocate_dynamic_stack_space): New function copied from
+ expand_builtin. Handle STACK_POINTER_OFFSET via
+ virtual_stack_dynamic_rtx. When STACK_POINTER_OFFSET is defined,
+ perform alignment by always reserving a multiple of STACK_BOUNDARY
+ stack bits. This avoids concern about whether sp itself or the top of
+ stack needs to be aligned; if we start with an aligned stack, we keep
+ it aligned.
+ (round_push): Use ADD and AND rather than DIV and MULT.
+
+ * expr.c (init_expr): Initialize some more vars.
+ (push_block): Use virtual_outgoing_args_rtx so don't need
+ STACK_POINTER_OFFSET here.
+ Merge extra and size more efficiently; no need to call force_operand
+ since memory_address is called.
+ (emit_push_insn): Pass type for FUNCTION_ARG_PADDING.
+ Use REG_PARM_STACK_SPACE instead of FIRST_PARM_CALLER_OFFSET.
+ To see if must copy address, check if it is a virtual register that
+ will be mapped to sp; only need check if not accumulating space
+ space for outgoing parms.
+ Ignore EXTRA if argument block has already been allocated.
+ (emit_library_call): Major rework to support calling sequences similar
+ to expand_call in calls.c, but only support a very small subset of
+ the conventions; abort if something outside our subset occurs.
+ Abort if incorrect mode is passed; we can't convert here since we don't
+ know the signedness.
+ (store_field): Check for virtual registers instead of hard registers
+ when seeing if stable.
+ (safe_from_p): Location in outgoing stack area is known to be safe.
+ (expand_builtin, BUILT_IN_ALLOCA): Use allocate_dynamic_stack_space.
+
+ * expr.h: Define current_function_outgoing_args_size and
+ locate_and_pad_parm; delete definition of get_structure_value_addr.
+ (ARGS_SIZE_RTX): Always return a valid operand.
+ (ARGS_SIZE_TREE): New macro.
+ (FUNCTION_ARG_PADDING): Accept MODE and TYPE like other
+ FUNCTION_ARG_... macros.
+ (FUNCTION_ARG_BOUNDARY): Provide default for new macro.
+ (MUST_PASS_IN_STACK): New macro.
+ (allocate_dynamic_stack_space): New function.
+ * tm-3b1.h, tm-3b1g.h, tm-apollo68.h, tm-crds.h, tm-mot3300.h:
+ Change definition of FUNCTION_ARG_PADDING to use TYPE instead of SIZE.
+

+ (arg_pointer_save_area, virtuals_instantiated): Likewise.
+ (invalid_stack_slot): No longer used.

+ outgoing args size and arg pointer save area.
+ No longer save or restore invalid_stack_slot.
+ (pop_function_context): Set up variables whose value is constant
+ throughout rtl generation.
+ (get_frame_size): No longer adjust by STARTING_FRAME_OFFSET.
+ (assign_stack_local): Use virtual_stack_vars_rtx instead of fp
+ until virtuals have been instantiated, then use fp.
+ Remove reference to obsolete invalid_stack_slot.
+ Can no longer be called with size == 0.
+ (assign_outer_stack_loc): Use virtual_stack_vars_rtx instead of fp.
+ Remove references to obsolete invalid_stack_slot.
+ Push to obstack of containing function when allocating rtx.
+ (put_var_into_stack): Only switch obstacks around making of
+ queue entry.
+ Replace call to parm_stack_loc with reference to info in proper
+ function.
+ (fixup_stack_1): Handle any virtual register instead of handling
+ just fp.
+ (instantiate_virtual_regs, instantiate_virtual_regs_1): New functions.
+ (use_variable, use_variable_after): Check for virtual register
+ instead of checking against ap and fp.
+ (parm_stack_loc): Function deleted.
+ (assign_parms): No longer need internal_arg_pointer.
+ Accept SECOND_TIME argument that suppresses rtl generation and
+ assignments to DECL_RTL. Used by integrate.c to recompute vars.
+ Don't use FIRST_PARM_OFFSET here; use virtual_incoming_args_rtx.
+ Replace test for nonstable incoming arg pointer.
+ If structure value address is treated as the first argument, add
+ it into the list of arguments; this means we can have a RESULT_DECL
+ in with the PARM_DECL's.
+ DECL_OFFSET is no longer needed by integrate.c.
+ Handle args passed by invisible reference.
+ Support new macro, SETUP_INCOMING_VARARGS, to save all registers used
+ for args including and beyond those for the current arg. Used for
+ non-ANSI varargs.
+ Pass locate_and_pad_parm data it needs to handle reg->stack boundary
+ if register parameters have assigned stack space.
+ If we received the function's incoming structure pointer as a
+ normal argument, update DECL_RTL of DECL_RESULT.
+ Round total argument size if required; similarly, always use at
+ least REG_PARM_STACK_SPACE bytes if defined.
+ (locate_and_pad_parm): Do not need PARM.
+ Major rework to do much of the job of aligning and padding stack
+ location. Now a void function wich is passed pointers to struct
+ args_size vars that are set to the argument position, size, and
+ initial offset.
+ Accept flag denoting if a parm was passed in a register and also
+ the current function declaration.
+ If register parameters are assigned stack locations and there is a
+ minimum required size for the area assigned to register parameters,
+ pad the stack position when a parameter not assigned to a register
+ is encountered.
+ Remove redundant code in MAX_PARM_BOUNDARY case.
+ (lookup_static_chain): Use virtual_stack_vars_rtx instead of fp.
+ (fix_lexical_addr): Move from explow.c.
+ If referencing variable that lives in the incoming argument area
+ of its parent and a separate ap is required, allocate a save area in
+ the parent for it and use it here. If no separate ap is require,
+ compute offset between ap and fp.
+ (trampoline_address): No need to push obstacks here.
+ (init_function_start): Initialize new vars; delete obsolete vars.
+ (expand_function_start): Don't need to handle case where incoming
+ structure return address is passed as hidden parameter here; now done
+ completely in assign_parms.
+ (expand_function_end): Save ap if a save area was made for it.
+ Set REG_FUNCTION_VALUE_P when copying address of returned
+ structure.
+ Be consistent in use of FUNCTION_... macros vs. hard_function_value.
+
+ * function.h (outgoing_args_size, arg_pointer_save_area): New fields.
+ (invalid_stack_slot): Obsolete, deleted.
+
+ * integrate.c: Major rework and simplification.
+ Split up vars into two classes. Those used for expand_inline_function
+ and children are now part of struct inline_remap. Most of the others
+ are for save_for_inline and its children.
+ (function_cannot_inline_p): The only type of arguments that will
+ cause us to reject inlining are variable-sized arguments; also
+ reject functions that return variable-sized objects.
+ For now, don't inline a nested function. We'll support this shortly.
+ Use current_function_returns_pcc_struct instead of duplicating test.
+ (save_for_inline): No need to set TREE_VOLATILE for parms.
+ Save outgoing args size in header.
+ Use unique copy of virtual reg rtx's.
+ Handle any required fixups for INSN_LIST forward-references.
+ Don't bother resetting dead static vars when we are done.
+ Need not save current_function_pretend_args_size.
+ (copy_for_inline): First copy all insns, then all REG_NOTES to avoid
+ problems with forward references.
+ (struct inline_remap): Move all previously-static vars used by
+ expand_inline_function and children into this structure. This avoids
+ potential problems due to recursive calls to expand_inline_function.
+ (expand_inline_function and children): Allocate a struct inline_remap
+ and pass to all children.
+ (expand_inline_function): Rework parameter handling by looking at
+ DECL_RTL and using it to determine what types of mappings need to be
+ done. Support objects passed by invisible reference. Put any
+ constant memory addresses into const_equiv_map. parm_map is no longer
+ used.
+ Likewise for the return value: consult DECL_RTL (DECL_RESULT)).
+ Don't allocate space for called function's frame until referenced.
+ No longer need special handling for insn following CALL.
+ Ignore USE whose argument has REG_FUNCTION_VALUE_P true.
+ Ignore setting function register if we don't have a mapping for it
+ (e.g., we are ignoring the result of the call).
+ Look at new SET_SRC for constant equivalences. Some new ones may
+ have resulted from constant folding.
+ Pass both new and old rtx to try_constants.
+ Discard NOTE_INSN_DELETED notes.
+ Copy insns first, then REG_NOTES, to avoid problems with forward refs.
+ (copy_parm_decls): Compute new address of parameter using the
+ constant equivalence map, which will contain the remapping of
+ the frame and argument pointer.
+ (copy_decl_tree): Likewise.
+ (copy_rtx_and_substitute): Handle references to frame and argument
+ pointers by allocating a space equal to the size of the frame and
+ incoming arguments, respectively, and setting a pseudo to point to
+ the start of each area. Set up an equivalence in CONST_EQUIV_MAP
+ between fp or ap and the actual address. Return the pseudo.
+ Don't need to deal with possibility of (SUBREG (CONST_INT)) since
+ we are only replacing register with other registers here.
+ No longer need to special-case PLUS and MEM; subst_constants will do
+ this work.
+ Update detection of sets of ap and fp.
+ (try_constants, subst_constants): Accept old and new rtx. They will
+ be isomorphic, with only register numbers changed. Use old rtx to
+ look up register in CONST_EQUIV_MAP and new rtx for substitution.
+ Correctly handle SUBREG of CONST_INT and CONST_DOUBLE.
+ Fix typos in handling of PLUS.
+ (access_parm_map, copy_address): Delete functions.
+ (try_fold_cc0): Handle both compare and test.
+ (fold_out_cnst_cc0): Rework to simplify and remove dubious cases.
+ (output_inline_function): Call assign_parms to perform any needed

+
+ * rtl.h (OUTGOING_ARGS_SIZE): New field in INLINE_HEADER.
+ (PRETEND_ARGS_SIZE): No longer needed.
+ (virtual_..., VIRTUAL_...): Define virtual register numbers and rtx.
+
+ * rtlanal.c (rtx_equal_p): Update comment on use of
+ REG_FUNCTION_VALUE_P.
+
+ * stmt.c (expand_goto): Just restore fp; non-local goto handler
+ will restore ap if needed.
+ (expand_return): Don't use STARTING_FRAME_OFFSET here.
+ (expand_end_bindings): Adjust fp in nonlocal-goto handler. If needed,
+ reload ap from its save area in the frame; allocate save area if none.
+ (expand_decl): Use new function allocate_dynamic_stack_space.
+
+ * toplev.c (rest_of_compilation): Instantiate virtual registers.
+ Clear rtx_equal_function_value_matters immediately after possibly
+ saving current routine for inlining.
+
+ * stupid.c (stupid_life_analysis): Don't try to allocate virtual
+ registers (which don't exist any more).

+
+ * STACK_ARGS_ADJUST: Arg is now a `struct arg_data' and it should

+ Truncate SFmode constants to single precision.
+

+ so stop using `else' structure.
+
+ * stmt.c (expand_return): Avoid moving void to void, in cleanups case.
+
+Mon Apr 3 18:04:33 1989 Richard Stallman (rms at sugar-bombs.ai.mit.edu)

+
+Sun Apr 2 13:02:26 1989 Richard Stallman (rms at sugar-bombs.ai.mit.edu)
+
+ * stor-layout.c (agg_mode): Use highest mode that has desired size.

+ redeclarations of typedef provided they agree.
+
+ * c-decl.c (start_decl): Do expand_decl on the decl that pushdecl
+ returns. If there was a prev. decl with a different type,

+
+Sat Apr 1 00:50:11 1989 Matthew Self (rms at sugar-bombs.ai.mit.edu)
+
+ * expr.c (convert_move): Modified to use mode classes
+ instead of refering to specific machine modes.
+
+ * expr.c (do_jump): Converted to use CONST0_RTX macro.
+ do_jmp no longer refers to any machine modes directly except
+ for VOIDmode!
+
+ * expr.c (compare, compare1): Modified to use CONST0_RTX
+ macro. No longer refers to any machine modes directly
+ except VOIDmode and BLKmode!
+
+ * machmode.def: Documented assumptions made about the order
+ of machine modes during mode widening.
+
+ * optabs.c (expand_binop, expand_twoval_binop, expand_unop,
+ emit_cmp_insn): Added mode widening which is independent of
+ specific machine modes. It assumes that we may widen to any
+ higher numbered mode of the same mode class.
+ NOTE: the checks for VOIDmode ops which were present in
+ QI and HI to SI widening are now present in all widening.
+ I assume this is correct. Also, widening is now possible
+ from QI to HI. This may or may not be a good thing....

+ (strength_reduce, record_giv): Set the `mode' field in V.
+ (can_eliminate_biv_p, eliminate_biv): Use that field.
+
+ * loop.c (struct iv_class): `init_insn' records what inits the biv.
+ Replaces `init_val_set' flag.
+ (strength_reduce): Update and test `init_insn' instead.
+ Use of a biv between its init and the start of the loop
+ does not preclude its elimination from the loop.
+ Setting a giv is ok for eliminating a biv, even if giv is "ignore",
+ since that just means giv will be combined with another.
+ Handle some DEST_ADDR givs for that purpose.
+ Test for giv-setting before check can_eliminate_biv_p.
+ New error check for replaceable giv whose value needed after loop.
+ (only_reg_use_p): New fn.
+
+ * expr.c (expand_expr): PLUS, MINUS with EXPAND_SUM:
+ Associate even harder.
+
+ * loop.c (strength_reduce): Treat all constant biv init vals like ints.
+
+ * loop.c (strength_reduce): Clear all_reduced when v->ignore is set;
+ the code to check this later didn't always do the job.
+
+ * loop.c (verify_loop): Set loop_continue.
+ (scan_loop): mention its value.
+ * rtl.h: Define NOTE_INSN_LOOP_CONT.
+ * stmt.c (expand_loop_continue_here): Output one.

+
+ * loop.c (scan_loop): Check each libcall for regs it uses

+
+ * tree.c (gcc_obstack_init): New function.

+
+ * gcc.c (default_compilers): Define __ASSEMBLER__ for .S file.
+
+ * tm-aix386.h (ASM_OUTPUT_LOCAL): Ok to use bss, since no shared libs.

+
+Mon Jan 28 12:52:11 1991 Richard Stallman (rms at mole.ai.mit.edu)
+
+ * tree.h (DECL_VIRTUAL_P): Renamed from TREE_VIRTUAL.
+ (struct tree_common): Eliminate virtual_flag.
+ (struct tree_decl): Add virtual_flag.
+
+ * Makefile.in (enquire.o): Pass -DNO_STDDEF.
+
+ * m68k.md (tablejump): Now have a define_expand that does
+ different things depending on CASE_VECTOR_PC_RELATIVE,
+ and a separate define_insn for each case.
+
+ * function.h (outer_function_chain): Declare the variable.
+
+ * tree.c (debug_obstack): Fix typos.
+ * tree.h (struct tree_common): Fix typo.
+
+ * Makefile.in (GNULIB1_TARGET, GNULIB2_TARGET): Variables deleted.
+ (gnulib): Depend on gnulib1.target and gnulib2.target explicitly.
+

+
+ * objc-actions.c (objc_finish): Renamed from lang_finish.
+ * objc-parse.y (program): Call objc_finish at the end.
+
+ * Changes from Matthew Self (mself@next.com):
+
+ * objc-parse.y: Since objc-parse.y was so out of date with
+ respect to c-parse.y, I started over with c-parse.y and
+ reintegrated the Objective-C modifications. Now that
+ Objective-C is working I hope that objc-parse.y will be kept
+ more up to date.... I did not re-integrate the lexer since I
+ don't have gperf working. I simply cut and pasted what
+ Stallman had in objc-parse.y. Someone with access to gperf
+ should re-generate this stuff.
+
+ * objc-actions.c (comp_method_with_proto,
+ comp_proto_with_proto): Stallman's change to use the
+ functions end_temporary_allocation and
+ resume_temporary_allocation is incorrect, since it always
+ leaves allocation temporary, whether it was before or not.
+
+ Perhaps the push and pop functions would do the trick....
+
+ * objc-actions.c (get_arg_type_list): Use new function
+ groktypename_in_parm_context.
+
+ * objc-actions.c (_OBJC_SELECTOR_REFERENCES_decl,
+ _OBJC_SELECTOR_REFERENCES_id): Removed.
+
+ * objc-actions.c (synth_module_prologue): Eliminated code to
+ forward declare the selector references array.
+
+ * objc-actions.c (init_objc_symtab): Eliminated code to
+ initialize "refs" field in objc_symtab structure (which is
+ now vestigial).
+
+ * objc-actions.c (build_selector_translation_table): Rewrote.
+
+ * objc-actions.c (build_selector_reference): New routine.
+
+ * objc-actions.c (build_message_expr, build_selector_expr):
+ Use new routine.
+
+ * config/tm-next.h (GO_IF_INDEXABLE_BASE): Don't use pc
+ relative addressing for LABEL_REF's. Since branch tables are
+ in the const section, we treat LABEL_REF's like SYMBOL_REF's
+ here. Otherwise invalid addresses were being generated.
+
+ * config/tm-next.h (CASE_VECTOR_PC_RELATIVE, CASE_VECTOR_MODE):
+ Use absolute branch tables rather than relative ones.
+
+ * config/tm-next.h (ASM_OUTPUT_MAIN_SOURCE_FILE_END): Output
+ an N_SO symbol with no name to mark the end of the module.
+ This is needed to support scattered loading on the NeXT.
+
+ * config/out-next.c (handle_pragma): Call to xrealloc had wrong args.
+
+ * configure: Entry for NeXT must set out_file to out-next.c.
+
+ * config/out-next.c: Typo: "flags" -> "flags.h"
+
+ * config/tm-next.h (LIB_SPEC): Brought up-to-date. There
+ are probably more changes needed here.
+
+ * c-decl.c (pushdecl_top_level): New function. This was
+ copied from an older version of g++.
+
+ * c-decl.c (init_decl_processing): Make alloca first arg sizetype.
+
+ * c-decl.c (groktypename_in_parm_context): New function.
+
+Mon Jan 28 07:07:01 1991 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * loop.c (loop_reg_used_before_p): Don't use INSN_LUID since INSN
+ might have been made by loop.c for an outer loop.
+
+ * loop.c (move_movables, strength_reduce): Replace register references
+ in REG_NOTES as well as PATTERN.
+
+ * loop.c (strength_reduce): Call maybe_eliminate_biv twice, not
+ three times.
+ (maybe_eliminate_biv): Don't abort if elimination fails even though
+ we thought it wouldn't. This can happen if certain insn patterns
+ aren't valid.
+ (maybe_eliminate_biv_1): Ensure that we do not change the insn at
+ all if all the required changes can't be done.
+
+Sun Jan 27 21:26:29 1991 Richard Stallman (rms at mole.ai.mit.edu)
+
+ * Makefile.in: Rename config-dir back to config.

+
+ * expr.c (expand_expr, case COND_EXPR): Disable special-case of
+ A ? B : C when B and C are simple. This is now done better by jump.
+
+Sat Jan 26 13:16:58 1991 Richard Stallman (rms at mole.ai.mit.edu)
+
+ * tree.h (TREE_PRIVATE, TREE_PROTECTED, TREE_VIRTUAL): New macros.
+ (struct tree_common): New flag fields.
+ * dbxout.c (dbxout_type): Get rid of conditional; can always use these.
+
+ * cccp.c (lookup_import): Do return -2 if file found.
+ (main): Handle `.m' suffix like `.S'.
+
+ * configure (m68k/next): Use out-next.c.
+
+ * WORD_SWITCH_TAKES_ARG and SWITCH_TAKES_ARG now give # of args.
+ * gcc.c (struct switchstr): New field `args' replaces `part2'.
+ (process_command): Record all the args a switch has.
+ (give_switch): Pass all the strings in `args'.
+
+ * tree.h (struct tree_common): Normally make `code' an enum tree_code.
+
+ * m68k.md (tablejump): New pattern.

+
+ * dwarfout.c: Include output.h.
+ (current_function_decl, asm_out_file): Explicit extern decls deleted.
+ (abort, fatal): Explicit extern decls deleted.
+ (NO_RETURN): Definition deleted.
+ (named_labels): Don't declare it.
+ (output_symbol): Don't use it.
+ (MAXPATHLEN): Don't define this. Don't include sys/param.h.
+ (output_source_file_die): Avoid limit on file name size.
+ (output_symbols_for_stmt): Deleted.
+ (output_symbols_for_block): Adapt to using BLOCK, not LET_STMT.
+
+ * configure: Renamed from `config'.
+ * config: Directory renamed back from config-dir.
+
+Sat Jan 26 1990 Ron Guilmette (rfg at ncd.com)
+
+ * README.DWARF: updated to reflect changes to dwarfout.c, the
+ inclusion of dwarf.h (and its changes) and the fact that the
+ DWARF support is no longer directly tied to the DG versions of
+ GCC.
+
+ * dwarfout.c: included a patch (provided by Ray Essick) to allow
+ dwarfout.c to properly get a value for MAXPATHLEN even on (old)
+ System V.3 systems.
+
+ * dwarfout.c: added support for long long types (as suggested by
+ Ray Essick).
+
+ * dwarfout.c: added support for the AT_comp_dir attribute. Also,
+ as part of this change, the name of the compilation directory is
+ no longer placed into in the .sources section.
+
+ * dwarfout.c: added support for the AT_addr_ranges attribute.
+
+ * dwarfout.c: added support for the AT_prototyped attribute.
+
+ * dwarfout.c: added support for the AT_src_info attribute. Also,
+ as part of this change, there is no longer a "special" entry
+ at the start of the .srcinfo section for each compilation unit,
+ and the contents of the "special" final entry in the .srcinfo
+ section have changed (to { -1, -1 }).
+
+ * dwarfout.c: modified to allow additional GNU DWARF extensions
+ to be generated whenever the corresponding extended attribute
+ codes are defined (presumably within a modified dwarf.h file).
+
+ * dwarfout.c: use the section names .srcinfo and .sources rather
+ than .finfo and .files. The additional specificity is warranted
+ because the DWARF information may someday include information
+ about object files as well as source files.
+
+ * dwarfout.c: fixed a bug where a type attribute was being generated
+ for functions and function types even when the return type was
+ void. "Standard" dwarf says that if the return type for a function
+ or function type is void then no type attribute should be generated
+ for the corresponding DIE.
+
+Sat Jan 26 04:22:08 1991 Michael Tiemann (tiemann at cygnus.com)
+
+ * cplus-lex.c (interface_strcmp): Handle String.String.Map.cc and
+ friends.

+ code from simple cast expression.
+
+Fri Jan 25 10:06:28 1991 Michael Tiemann (tiemann at cygnus.com)
+
+ * cplus-decl.c (pushtag): Don't call `pushdecl' if the type's name
+ is anonymous, lest we recurse ad infinitum.

+
+ * sdbout.c (sdbout_symbol): Apply changes in dbxout.c to deal with
+ SUBREG. Don't emit a symbolic definition for variables that can't
+ be represented.
+
+Thu Jan 24 21:18:15 1991 Richard Stallman (rms at mole.ai.mit.edu)
+
+ * config: Conditional for setting $os was backward.
+ Also mention name of make-var file if one exists.
+
+ * out-i386.c: Delete a large piece of accidental insertion.
+
+ * dwarfout.c: Don't include c-tree.h or cplus-tree.h.
+ (INT_TYPE_SIZE, etc.): Define them if not overridden.
+ (fundamental_type_code): Distinguish types by TYPE_PRECISION.
+ But also check for the built-in C type names.
+
+Thu Jan 24 15:23:17 1991 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * gcc.c (default_compilers): Pass all args starting with "O" to
+ cc1 so that -O2 is passed along.

+ a SEQUENCE.
+
+ * loop.c (check_dbra_loop): Use emit_jump_insn_before when writing
+ out compare and jump sequence, not emit_insn_before, to ensure that
+ if we only write one insn that it is a JUMP_INSN.
+
+ * toplev.c (flag_rerun_cse_after_loop): New: -frerun-cse-after-loop.
+ (rest_of_compilation): Rerun cse after loop if desired.
+ (main): Add support for -O2.
+ Prescan args for -O and -O2 to set default values for many -f options.

+
+ * Makefile.in (GNULIB1, GNULIB1_TARGET): Renamed from GNULIB*.

+
+ * reload1.c (eliminate_regs): If we have a non-paradoxical
+ (subreg (pseudo)) and the pseudo has an equivalent memory
+ location, replace the SUBREG because find_reloads may do it.
+
+Tue Jan 15 01:41:28 1991 Richard Stallman (rms at mole.ai.mit.edu)
+
+ * loop.c (scan_loop): Condition for movability was wrong.
+ A reg that isn't necessarily set may be unsafe
+ even if used only inside the loop.
+ However, a reg used only in the same basic block after the set is safe.
+ So is a reg that isn't a user-level variable.

+ source for FILE pointer.
+ (yylex, do_pending_inlines): Call it.
+

+ fixed to return it.
+
+ * cplus-lex.c (reinit_parse_for_block): New function, with most of
+ the guts of reinit_parse_for_method. Magic argument IS_TEMPLATE
+ chooses a set of error messages.
+ (reinit_parse_for_method): Call it.

+ (free_token_list): Renamed from free_keyword_list. Free the strings.
+ (do_assert, do_unassert): Considerably changed.
+ (check_assertion): Somewhat changed.
+ (check_macro_name): Extra arg contributes to error message.
+ * cexp.y (yylex): Parse everything as a name if keyword_parsing.
+ (rule for assertions): Set, then clear, keyword_parsing.
+ (keywords): Allow empty sequence. Allow nested parens.
+
+Sat Jan 12 12:18:00 1991 Richard Stallman (rms at mole.ai.mit.edu)
+
+ * c-typeck.c (build_unary_op): Make better code for simple casts.
+
+ * reload.c (find_reloads): Computing reload_when_needed, don't neglect
+ operands that don't have output reloads.
+
+ * cse.c (refers_to_mem_p): At check_addr, handle PLUS inside CONST.

+
+ * tm-next.h (LIB_SPEC, STARTFILE_SPEC): Don't support -p.

+ (lookup_nested_type): New function.
+ (pushtag,lookup_tag,xref_tag): Handle nested classes.
+ (finish_function): Add comment about obscure argument passing
+ convention for static method calls (at the call site). Also, don't
+ call operator delete with NULL pointer. Call it with

+ (globalize_nested_type): New function. Used when we learn that a
+ type which initially appeared to be nested should be defined in the
+ global scope instead.
+ (grokdeclarator): Call `globalize_nested_type' when grokking an
+ as-yet undefined class type.
+ * cplus-dem.c: Updated to handle qualified (i.e. nested) types.

+ involved.
+ (yylex): Recognize SCOPED_TYPENAME and TYPENAME_SCOPE tokens.
+ Also, recognize '<' and '>' separately from ARITHCOMPARE so we can

+ type for nested types.
+ (DECL_NESTED_TYPENAME): An identifier pointer that makes the name of

+ * regclass.c (regclass): reg_n_sets is one per set. It does not

+

+Fri Jan 4 12:13:14 1991 Michael Tiemann (tiemann at cygnus.com)
+
+ * cplus-class.c (modify_vtable_entries): In case we are modifying
+ the main vtable, start with the vtable that comes from the immediate
+ baseclass, not the most base class. This is needed because later

+
+ * expmed.c (emit_stor_flag): Try to convert some comparisons with
+ 1 and -1 to comparisons with zero.
+ Explicitly test sign bit of STORE_FLAG_VALUE rather than testing it
+ for being less than zero.

+ instead, test the relevant sign bit.
+ Use GET_RTX_CLASS instead of comparison_code_p.
+ * loop.c (get_condition): Likewise.
+
+ * recog.c (validate_change): Eliminate duplicate code by always
+ saving the change. If in_group == 0, call apply_change_group.
+ (apply_change_group): If recog_memoized fails, see if we have a
+ CLOBBER at the end. Use validate_change to replace the pattern
+ with one without the CLOBBER if so; later we will verify that change.
+
+ * tree.c (stabilize_reference_1): Now static; also, define as forward
+ reference at start of file.
+
+ * rtl.def: Add new field in DEF_RTL_EXPR macro to give the "class"

+ agree with the order written.
+ (output_epilogue): Remove extraneous tests.
+
+Thu Jan 3 13:32:54 1991 Richard Stallman (rms at mole.ai.mit.edu)

+
+ * By Jim Wilson.
+ * tree.c (stabilize_reference): Modified to call stabilize_reference_1
+ instead of save_expr.
+ (stabilize_reference_1): New function. For arithmetic operator trees,
+ recurse on the subtrees. Otherwise, put a SAVE_EXPR around the
+ tree if it has side-effects.
+
+Thu Jan 3 12:37:56 1991 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * reload1.c (choose_reload_regs): Only set reload_when_needed to

+Wed Jan 2 07:53:04 1991 Michael Tiemann (tiemann at cygnus.com)
+
+ * sparc.md (fix_truncdfsi2 recognizer): xoperands must have 3

+
+ * reload1.c (reload_as_needed, forget_old_reloads_1): Don't clear

+
+ * emit-rtl.c (emit_insn_before, emit_insn_after, emit_insn): Return
+ something sensible if a SEQUENCE of length zero was passed.
+ We no longer make a SEQUENCE with XVEC == 0, so don't test for it.
+

+
+ * cplus-typeck.c (c_expand_return): Handle case when we try

+
+Sun Dec 30 21:08:32 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * tm-a29k.h (TARGET_VERSION): Can't use target_flags since we can
+ be called from gcc.c.
+
+ * tm-rs6000.h (REG_ALLOC_ORDER): Put r12 after r13; it might be
+ holding a DImode value and so might be very expensive (we won't
+ worry about TImode).

+Sun Dec 30 12:02:03 1990 Michael Tiemann (tiemann at cygnus.com)
+
+ * tm-sparc.h (PRINT_OPERAND): Put 'R' case before REG so that it

+
+ * sparc.md: (pattern for converting DFmode to SImode): Second
+ argument to `output_asm_insn' should be `operands', not zero.
+ (tablejump): The jump insn is "jmp", not "jump".
+ (gen_fixtruncdfsi2): operands[2] should get the pseudo, not
+ operands[3] (which is nonexistent).
+ (call): Fix typo which had %o7 being emitted as %o.
+ (various patterns): Fixed places where match_operand had the wrong
+ operand number.
+
+Sat Dec 29 17:27:00 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * sparc.md: cc_status no longer handles condition code updates.
+ Instead, condition codes are explicitly set and used via
+ hard register 0. Special attributes specific to condition codes
+ (such as whether conditional branches should test the integer or
+ floating-point condition codes, or that the condition codes cannot
+ be tested for a condition which would test the overflow bit) are
+ handled by encoding the attribute in the mode for the condition
+ code register.
+ (type attributes): type "unary" insns have one input operand (1)
+ and one output operand (0)
+ type "binary" insns have two input operands (1,2) and one output (0)
+ type "compare" insns have one or two input operands (0,1) and no output
+ type "move" and type "arith" have been deleted.
+ (prescan attribute): Deleted. Machine description now puts
+ floating-point zero in registers when needed.
+ (use_cc attribute): Deleted.
+ (fpcc define_delay): No longer depend on "use_cc" attribute.
+ Also, fpcc delay characteristics hold for "fpcc" type insns.
+ (cc attribute): Deleted.
+ (cmpxx patterns): Now written as `define_expand's so we can stow
+ away operands. When the pattern that will use the results of the
+ conditional test is emitted, it can use these operands to figure
+ out the right way to emit the compare.
+ (bcc patterns): Rewritten to emit comparison (based on stowed-away
+ info) before emitting branch.
+ (scc patterns): Handle all the cases with branch-free code.
+ Added new pattern to recognize (x + (i == 0)).
+ (movsi pattern recognizer): Split into two patterns so that e.g.
+ "(set:SI (mem:SI ...) (const_int 5))" is never considered valid.
+ Instead this has to be a two-insn sequence.
+ (mov{hq}i pattern recognizers): Ditto.
+ (movstrsi): Force operands[2] out of memory if it was in memory.
+ ({zero,sign}_extendXY): Now written as `define_expand's instead of
+ `define_insn's for more accurate machine modeling.
+ Added new pattern to optimize bit-field compares.
+ (floatsisf2 patterns): Delete redundant setting of "in_call_delay"
+ attribute.
+ (fix_trunc{sf,df}si2 pattern): Use clobberable register in which
+ the conversion can take place. Used to use %f30,%f31.
+ ({add,sub}di3 pattern): Put explicit clobber of (reg 0) in the
+ pattern.
+ (negdi2 pattern): Ditto.
+ Added new patterns to handle merging of addition/subtraction with
+ condition code testing (with (reg:CC_NOOV 0)).
+ ({and,ior,xor}cbsi3 pattern): Obsolete. Deleted.
+ Added patterns to represent setting of condition codes in addition
+ to performing logical operations.
+ ({neg,abs}df2 pattern): Use `R' print letter to overcome the need
+ to use a C action instead of a simple template.
+ (ash{l,r}{hi,qi}3): Define patterns for shifts on sub-SImode
+ operands.
+ (jump pattern): Use `*' print code to obviate the need for a C
+ action when a template can do.
+ (tablejump pattern): Ditto, with `^' code as well.
+ Deleted `define_split's that were used to handle mem-mem moves in
+ the case of PIC generation. Since all move insns are emitted and
+ maintained as SPARC-valid insns, these should no longer be needed.
+ (various patterns): (HI ...) is spelled (HI:SI ...). Also, use
+ `gen_lowpart' instead of building subregs directly.
+ New `define_split's were added to split scc insns into simpler
+ components which have single-insn templates.
+ Fixed a return peephole when returning a SFmode value (it was
+ missing the "ret"!).
+ Lots of complicated peepholes that brought cc testing and
+ arithmetic operations together were deleted. This is because the
+ combiner should now handle all these cases.
+
+ * out-sparc.c (sparc_compare_op{0,1}): New global variables.
+ Used to hold the operand(s) to compare insns in lieu of emitting a
+ compare.
+ (reg_or_cc0_operand): Deleted.
+ (normal_comp_operator): New function.
+ (cc_arithop): Now returns 0 for PLUS and MINUS.
+ (cc_arithopn): Now returns 0 for XOR.
+ (gen_compare_reg): New function.
+ (sparc_address_cost): Simplified because it turns out it doesn't
+ matter what is returned for illegitimate addresses.
+ (hard_regno_mode_ok): Updated to use these new #defines.
+ (C_MODES): New #define, for condition code modes.
+ (S_MODES): Ditto, for single-word (and smaller) quantities.
+ (D_MODES): Ditto, for double-word (and smaller) quantities.
+ (T_MODES): Ditto, for tetra-word (and smaller) quantities.

+
+ * combine.c (try_combine): Fix typo in loop over I1 with PARALLEL

+
+ * jump.c (jump_optimize): When moving USE insns from before jumps to

+ If result is constant, just return it.
+ Accepts an argument saying how to normalize the result and does

+ code register. As a temporary measure, NOTICE_UPDATE_CC is used
+ to track swapped cmpsi cases.
+
+ * m88k.md (shift patterns): Deal with TARGET_*_LARGE_SHIFT
+ uniformly with define_expand. Make gen_lshlsi3 generate ASHIFT
+ and eliminate the optimization patterns using ASHIFT. Eliminate
+ other optimization patterns that will be handled by combine.

+
+ * stmt.c (expand_start_loop{,_continue_elsewhere}): Return pointer
+ to nesting structure (new type stmt_nesting).
+ (expand_exit_loop{,_if_false},expand_continue_loop): Accept pointer
+ to nesting structure, substitute loop_stack if 0 (same behavior as
+ before when there was no argument), so F90 CYCLE and EXIT statements
+ (like C's continue and break stmts) can refer to other than the
+ innermost loop.
+ (expand_start_cond): Uses new names for if-related labels that
+ reflect addition of "elseif" call, and sets endif_label to whatever
+ exit_label gets set to (so we don't generate two identical labels
+ for languages from which if is exitable via expand_exit_something).
+ (expand_start_elseif): New function, used by Fortran.
+ (expand_start_else): Moved above _end_cond so these four functions
+ appear in the order they get called; uses new names, and fills in
+ only endif_label if needed, not exit_label.
+ (expand_end_cond): Handles end of any if, not just if-without-else.
+ Generates both labels for next else/elseif pending (there was none)
+ and the endif itself, if they exist (and there will always be at least
+ one).
+ (expand_end_else): Gone, call expand_end_cond instead.
+ * c-parse.y, cplus-parse.y, objc-parse.y: Pass new 0 argument to
+ expand_..._loop_... to indicate the innermost loop; call
+ expand_end_cond instead of expand_end_else.
+ * tree.h: Typedef for stmt_nesting returned by expand_start_loop...
+ and change their return types accordingly.

+
+ * combine.c (check_asm_operands): Delete from here.
+ * recog.c (check_asm_operands): Move to here; no longer static.
+ (validate_change): Don't assume change is valid is asm_noperands >= 0.
+ If recog_memoized returns < 0, accept change if asm_noperands >= 0
+ and check_asm_operands returns non-zero.
+ (apply_change_group): Likewise.
+ (validate_replace_rtx_1): Swap operands on commutative operation
+ if first is constant.
+ Use plus_constant to simplify a PLUS with CONST_INT as second operand.
+
+ * reload.c (find_equiv_reg): We must have a stable SP if GOAL is
+ a MEM that uses SP.
+
+ * combine.c (try_combine): Don't do anything if I2 or I1
+ has an ASM_OPERANDS and CLOBBERS; we'll need those clobbers
+ and it is too messy to try to get things set up correctly.
+
+Sun Dec 9 22:07:41 1990 Richard Stallman (rms at mole.ai.mit.edu)
+

+ against type.
+
+Sat Dec 8 10:40:00 1990 Tom Wood (wood at dg-rtp.dg.com)
+
+ * m88k.md (attributes): Reorganize and include a block diagram.
+ Make better use of defaults.
+ * m88k.md (peephole), out-m88k.c, tm-m88k.h (short_branch): Add
+ the sparc peepholes for changing bsr/br into bsr.n/addu or
+ bsr.n/subu. Install the length attribute for this. Requires the
+ use of `def' to accomodate broken assemblers in the bsr.n/addu
+ case.
+
+Fri Dec 7 06:12:43 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)

+Tue Dec 4 16:12:21 1990 Tom Wood (wood at dg-rtp.dg.com)
+
+ * tm-m88k.h, out-m88k.c, m88k.md: More cleanups: introduce
+ POWER_OF_2 for tests (x && (x & (x-1) == 0); rename predicate
+ functions *_p instead of *_operand; cleanup addsi3 insns; simplify
+ udivsi3 insns; simplify memory shift insns; make LOW_SUM and HIGH
+ SImode instead of VOIDmode; add a predicate to the increment and

+ xm-m88kdgux.h.
+ * tm-m88k.h, out-m88k.c, m88k.md: Eliminated the fixed literal
+ synthesis register. Reworked the addressing method to be like the
+ sparc (uses HIGH and LO_SUM). Numerous cleanups. These changes
+ are based on work done by Steve Chamberlain (steve@cygnus).
+ * tm-m88k.h, out-m88k.c (BLOCK_PROFILER, FUNCTION_BLOCK_PROFILER):
+ Implemented.
+
+Mon Dec 3 15:19:04 1990 Richard Stallman (rms at mole.ai.mit.edu)
+

+
+Sun Dec 2 17:47:28 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * reload1.c (eliminate_regs, case ASM_OPERANDS): Fix typo in testing
+ for changed vector.
+
+ * out-rs6000.c (output_epilogue): Fix typo restoring general registers.
+ (print_operand): Add new option %H.
+ * rs6000.md: Add (clobber (reg:SI 64)) to many patterns even though
+ they don't clobber MQ to allow combining to work well. This will be
+ removed once combine knows how to add clobbers when required.
+ Change patterns to reflect new canonicalization rules.
+ Where we have (and (xshift)), add patterns for (zero_extend (xshift)).
+ (andsi3, xorsi3): Fix bug in case where two insns are needed.
+ (moveti): Don't call change_address when in reload.
+ (sign_extend): Add patterns for sign extend preceeded or followed by
+ one of the shifts it will do. Use %H to output the merged shift.
+
+ * out-romp.c (print_operand): Allow exact_log2 result to be zero.
+ * romp.md: Likewise.
+ * tm-romp.h (CONST_OK_FOR_LETTER): Likewise.
+
+ * a29k.md (type attribute): Add types for floating-point insns.
+ (in_delay_slot attribute): Update to allow for new types.

+ floating-point operand.
+ (cpeq, feq, deq, etc): New patterns.
+ (floating-point arithmetic): Add support for 29050 insns and
+ accumulators; indicate function unit usage.
+ (ior/and patterns): Put NOT as second operand.
+ (orn insn): New, for 29050.
+ (load patterns): If using match_operator, make it the highest operand
+ number.
+ (loadm insns): Add workaround for rev A1 bug on 29050.
+ (negsf2, negdf2): Don't use XOR to negate on 29050.
+ (movsf, movdf): Add support for accumulators on 29050.
+ (movsi, movhi, movqi): No need to support special->special copies.
+ Support consthz insn on 29050.
+ (compare, scc, and branch insns): Rework to not use cc0. Use a pseudo
+ register instead. Compare doesn't generate any code, but merely
+ saves the operands. scc and branch then emit the appropriate compare
+ and jump (if branch) insns.
+ (tstsi): Delete pattern; not used when no cc0.
+ (peepholes): Remove peepholes to convert jumps to scc insns; now
+ done in jump.c.
+ * out-a29k.c (a29k_compare_*): New variables.

+ Add new code %J.
+ * tm-a29k.h (TARGET_VERSION): Say if compiling for 29050.
+ (TARGET_FLAGS): Add -29000 to turn off support for 29050; this is
+ still the default.
+ (various register macros): Add support for the floating-point
+ accumulators on the 29050.
+ (CONST_OK_FOR_LETTER): Use 'O' for a constant that can be set using
+ conthz on the 29050; keep old definition for 29000.
+ (STORE_FLAG_VALUE): Now 0x80000000.
+ (ASM_FILE_START): Write ".cputype 29050" when compiling for 29050.
+
+ * combine.c (subst): Put NOT, NEG, MULT, PLUS, and MINUS as the
+ first operand of commutative operations. Note that NOT used to be
+ put as the second operand but it has always been assumed that
+ MULT would be the first operand in address expressions, so we have
+ to change the previous canonicalization. This is possible now that we
+ have eliminated the andcbm3 operations.
+ * i860.md (andnot): Remove obsolete andcbsi3 name and place NOT
+ as first operand.
+ * m68k.md (fpm*): Delete patterns with MULT as second operand and
+ use "@" construct when possible.
+ * m88k.md (and.c, ior.c): Remove obsolete andcbsi3 and iorcbsi3 names.
+ Delete patterns with NOT as second operand.
+ (xor.c): Rewrite in new canonical form.

+ Remove obsolete names andcbsi3, iorcb3, and xorcbsi3.
+ Rewrite xnor into new canonicalized form.
+ Add mode to HIGH and LO_SUM operations.
+ * vax.md (bic*): Remove obsolete andcbm3 names.
+ Put NOT as first operand when both generating and recognizing RTL.
+ (jlbc): Rewrite with NOT as first operand.
+
+Sun Dec 2 17:08:16 1990 Richard Stallman (rms at mole.ai.mit.edu)

+
+Sat Dec 1 16:31:30 1990 Ron Guilmette (rfg at ncd.com)
+
+ * dwarfout.c (lookup_filename, dwarfout_finalize): changed from
+ maintaining a linked list of filename entries to maintaining an
+ (expandable) array of filename entries instead. Also, changed
+ code so that *all* filename strings are output (to the .files
+ section of the asm file) in one swell foop just as the asm file is
+ being finalized rather than writing out new filenames one-by-one
+ as they arise (as previously). This circumvents a problem caused
+ by rfg's naive assumption that assemblers kept a stack of prior
+ section names (of depth > 1) which could be successively popped
+ via multiple `previous' directives. For some assemblers, the
+ depth of the stack is only 1 and they can get confused if you do
+ two (or more) `previous' directives in a row. Anyway, it is no
+ longer either necessary or useful to do that, so who cares.
+
+ * dwarfout.c: added code to output newlines to the asm file just
+ prior to each and every change of section (for better readability
+ of the asm files).
+
+ * dwarfout.c: changed code so that if DWARF_DESCRIBE_USED_EXTERNS
+ is defined, it forces DWARF_LOCATION_ATTRIBUTES to also be defined.
+
+ * dwarfout.c: changed code so that if DWARF_LOCATION_ATTRIBUTES
+ is defined, it forces DWARF_DESCRIBE_FILES to be defined (to `1').
+
+ * dwarfout.c: changed code so that if DWARF_DESCRIBE_FILES is not
+ already defined (in the user's tm.h file) it will automatically be
+ defined (by default) to `1'. Also changed all instances of
+ `#ifdef DWARF_DESCRIBE_FILES' to `#if DWARF_DESCRIBE_FILES'.
+ The user must now intentionally *disable* this feature (by
+ defining DWARF_DESCRIBE_FILES to `0' in his tm.h file) if he
+ wishes to have the additional information about files suppressed.
+
+ * dwarfout.c: changed comments relating to optional defines for
+ extended GNU DWARF features to include more information and to
+ add some additional clarity.
+
+Sat Dec 1 16:00:34 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * combine.c (subst): Call reverse_condition instead of
+ reverse_comparison.
+ We are allowed to reverse floating-point EQ and NE comparisons.
+
+ * combine.c (subst): Call simplify_and_const_int for all AND
+ and ZERO_EXTEND cases and all cases where we make one of them.
+ Remove all other code in AND and ZERO_EXTEND cases.
+ (simplify_and_const_int): Rewritten to follow a consistent model
+ of tracking what AND's need to be done and which bits are not
+ significant. Consistently try a ZERO_EXTEND for all cases where
+ the result is an AND with a mode-wide mask. Move all remaining
+ cases from AND any ZERO_EXTEND cases from subst.

+
+Fri Nov 30 10:39:04 1990 Michael Tiemann (tiemann at cygnus.com)
+
+ * cplus-decl.c (finish_function): Use CLASSTYPE_ASM_WRITTEN instead
+ of TREE_USED to indicate that we need debugging info for
+ TTYPE.
+ Note that nobody ever sets EXTENDED_DBX_DEBUG. For now,
+ change to test DBX_DEBUG. For later, change everything to
+ key off of EXTENDED_DBX_DEBUG.
+ Also, set `warn_return_type' to one always, since this warning
+ is too valuable to lose.
+ * cplus-tree.c (lang_output_debug_info): Don't test TREE_USED. That
+ field is already used by other routines, and we have all we need now
+ in CLASSTYPE_ASM_WRITTEN.

+ insn in reg_last_set as if it was a single SET.
+
+ * combine.c (gen_lowpart_for_combine): Call gen_lowpart for CONST_INT.
+ When making a new MEM, copy MEM_VOLATILE_P and MEM_IN_STRUCT_P.
+ If cannot recognize the argument, just form a SUBREG; usually,
+ it won't be recognized, but sometimes will allow further
+ simplifications.
+
+ * regclass.c (reg_scan): Save size of uid map; reallocate if
+ we have more registers than we allocated.
+ Leave some extra room in map.
+
+ * stmt.c (emit_case_nodes): Supply missing argument to emit_cmp_insn.
+
+ * fold-const.c (decode_field_reference): Add missing arg declaration.

+
+ * loop.c (scan_loop): Properly set SET_SRC in movables entry for

+
+ * stmt.c (expand_end_loop): Stop looking for branch to the loop
+ exit when we hit a NOTE_INSN_BLOCK_{BEG,END}.
+ * jump.c (duplicate_loop_exit_test): Likewise.
+ Also, only copy line-number notes.
+
+ * integrate.c (expand_inline_function): Call expand_expr for the
+ arguments before allocating maps that are based on register numbers.
+
+ * loop.c (loop_reg_used_before_p): Accept new argument, SET, to

+ (scan_loop): Pass new arg to loop_reg_used_before_p.

+
+Thu Nov 29 02:42:35 1990 Michael Tiemann (tiemann at cygnus.com)
+
+ * version.c: Bump version number to 1.90.04.
+
+ * toplev.c (rest_of_compilation): If FLAG_PIC is nonzero, emit any
+ special PIC code once we start really compiling a function (i.e., we
+ are not in an inline function). Inline functions cannot
+ meaningfully hold PIC code because there is no notion of position
+ independence in code that isn't really being written down.
+
+ * Makefile.in: Don't build cplus-cadillac.o by default. Build
+ cplus-edsel.o instead. Until Lucid frees their programming
+ environment, their Cadillac will always be an Edsel to GNUsers.
+
+ * stmt.c (fixup_gotos): Change loop to run in two passes so that
+ cleanups don't experience a race condition.
+ (expand_cleanups): Replace Nov 5 word-around with consistency check.
+ The same cleanups should never be run twice.

+
+ * cplus-decl.c (pushdecl): Don't warn about static/extern conflicts

+ (prev_insn_cc0*): Just store last rtx assigned to cc0 in prev_insn_cc0.
+ (find_comparison_args): New function.
+ (fold_rtx): Folded value of cc0 is the value previously stored into it.
+ Rework handling of comparisons: use find_comparison_args to see what
+ is being compared. If they are constants, compute the result of the
+ comparison. If not, see if the two operands are equivalent (only for
+ non FP or non-IEEE FP). Then see if we have already seen a comparison
+ involving these operands that lets us give a value to this comparison.
+ True comparisons return STORE_FLAG_VALUE, not 1.
+ (fold_cc0): Deleted.
+ (predecide_loop_entry): Call cse_insn on a copy of each insn at the

+
+ * emit-rtl.c (make_insn_raw): No longer have JUMP_LABEL for INSN.

+ files.
+
+ * rtl.def: Remove Sep 26 that added JUMP_LABELs to INSN and
+ CALL_INSN.
+ * rtl.h: Add REG_LABEL register note. For INSN and CALL_INSN, the

+ * jump.c (jump_optimize): Revert to clearing JUMP_LABEL field of
+ JUMP_INSNs only.
+ (mark_jump_label): If INSN is an INSN or a CALL_INSN, add a

+ ??? Once recorded, this information appears never to be used.
+
+ * jump.c (delete_jump): The deletion of INSN must take place when
+ INSN is a simple jump. Also, don't try to optimize if we come
+ across an insn with the reorg-generated pattern (USE (INSN ...)).
+
+ * cplus-lex.c, cplus-dbxout.c: Remove vestigial support for dumping
+ and undumping the compiler.
+

+ _IBMR2. This hair will disappear when pcccp support is merged, but
+ needed for now.
+ * cplus-tree.h: Conditionalize use of non-int bitfield types on
+ ONLY_INT_FIELDS. Also, remove duplication declarations of
+ get_temp_name, get_temp_aggr, and get_temp_regvar; add declaration

+
+Sun Oct 28 15:01:19 1990 Richard Stallman (rms at mole.ai.mit.edu)
+

+ advantage of new 2.0 optimization capabilities.
+ * old-sparc.md, tm-old-sparc.h, out-old-sparc.c: These are copies of

+ measuring performance of old vs. new machine description idioms.
+
+Sun Oct 28 00:22:40 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+

+
+ * vax.md (call_value_pop): Use correct operand number for number

+
+ * tm-romp.h (EXTRA_CONSTRAINT): Ensure we ignore reg_renumber if

+
+Fri Oct 26 00:46:09 1990 Michael Tiemann (tiemann at cygnus.com)
+
+ * cplus-tree.h: Declare `build_type_conversion' once instead of
+ three times.
+
+ * loop.c (loop_skip_over): Handle machines without cc0.
+ (labels_in_range_p): Fixed typo where this function returned 0 when
+ it meant to return 1.
+ (check_for_endtest): New function. Returns non-zero when
+ argument is a simple conditional test insn (suitable for being the
+ endtest of a loop).
+ (strength_reduce): Use `check_for_endtest' to identify the endtest.
+ Also fixed some typos in comments.
+ (can_eliminate_biv): Use `check_for_endtest' here, too.
+ (get_condition): Generalized to handle machines without cc0. Now

+ (delete_jump): Made to work without cc0_rtx.
+
+Fri Oct 26 00:01:27 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * reorg.c: Conditionalize references to CC0_RTX on HAVE_cc0.
+
+ * reload.c (find_reloads): For the `o' constraint, if IND_OK is
+ true, use offsettable_memref_p instead of the nonstrict version.
+
+ * jump.c (delete_jump): If HAVE_cc0 is not defined, it is not safe to
+ delete previous insn that sets a condition code register, because it
+ might not be dead. Rework to look at all registers dying in this insn
+ and delete the first previous insn that sets any such register if that
+ is all it does.
+
+ * jump.c (jump_optimize): Remove extraneous call to next_active_insn
+ in optimization of "if (...) x = 1; else ...; if (x) ...".

+
+ * m88k.md, tm-m88k.h, out-m88k.c: Rewrites by wood@dg-rtp.dg.com.
+ * tm-m88kdgux.h, tm-v88r32.h, tm-m88ksvr4.h: New files.

+
+Thu Oct 25 14:54:18 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * jump.c: Now includes insn-config.h.
+ (jump_optimize): inequality_comparisons_p takes only one operand again.
+ (can_reverse_comparison_p): Handle case where a register is used
+ for the condition code; if we can't easily find the COMPARE that
+ was used to set the register, say we can't reverse the comparison.
+ * Makefile.in (jump.o): Now includes insn-config.h.
+
+ * jump.c (jump_optimize): Put back change removed on Oct 21st;
+ emit_store_flag has now been updated.
+
+ * rtlanal.c (inequality_comparisons_p): Reject any ordered
+ comparison; we need not just reject when comparing against
+ cc0_rtx.
+ * recog.c (next_insn{,s}_test_no_inequality): inequality_comparisons_p
+ again has only one operand.
+ * genattrtab.c (cc0_rtx): No longer needed; remove change of Oct 21.
+
+ * genconfig.c (have_cc0_flag): New variable.
+ (walk_insn_part): Set it when we see CC0.
+ (main): Write #define HAVE_cc0 when it is set.
+ * flow.c: Now includes insn-config.h.
+ * Makefile.in (flow.o): Likewise.
+
+ * combine.c (subst): If X and FROM are the same register number,
+ but in different modes, force the combine not to be done.
+ Add missing initialization of undobuf.storage.
+
+Thu Oct 25 11:34:35 1990 Michael Tiemann (tiemann at cygnus.com)
+
+ * sched.c (new_sometimes_live): Protect this function in case it is
+ called with (OFFSET,BIT) that evaluates to >= MAX_REGNO.
+
+ * jump.c (sets_cc0_p): Conditionalized to abort if called when
+ machine does not support cc0.
+
+ * rtlanal.c (reg_set_p): Now non-static.
+ * rtlanal.c (rtx_varies_p): Handle LO_SUM more accurately.
+ * rtlanal.c (find_next_ref): New function. Returns the insn that
+ next references REG after INSN, or 0 if REG is clobbered before next
+ referenced or it cannot easily find a reference to REG.
+
+ * recog.c (next_insn_tests_no_inequality): Conditionalized on
+ HAVE_cc0.
+
+ * rtlanal.c (inequality_comparisons_p): Takes new argument
+ THIS_CC0_RTX which is the rtl for the condition code value we are
+ concerned about testing. All callers changed.
+
+ * flow.c (propagate_block,mark_used_regs): Conditionalize
+ specialized cc0 handling only if HAVE_cc0 is defined.
+
+ * genemit.c (gen_exp): In REG case, If CC0_REGNUM is defined,
+ save space by using REG_CC0_RTX instead of allocating a new
+ (REG, mode, CC0_REGNUM) rtx if the mode is SImode.
+
+ * final.c (output_addr_const): Handle PC for P.I.C. code generation.
+ Also, put parens around CONST expressions so that precedence can be
+ maintained.
+ * final.c (final_scan_insn): Don't look for redunant compares
+ except when HAVE_cc0 is defined.
+ Also, use `find_cc' to locate the rtx functioning as the
+ condition code register in order to perform appropriate calls
+ to `alter_cond'.
+
+ * expr.c (expand_expr): Supply missing arg in calls to `store_expr'.
+
+ * expmed.c (emit_store_flag): New argument COMPARISON is the
+ comparison operation whose result we store.
+
+ * recog.c (offsettable_address_p,adj_offsettable_operand): Use
+ `plus_constant_for_output' instead of `plus_constant' since we
+ are testing conditions which rely on being able to add small
+ offsets to e.g. LO_SUM operands.
+ * explow.c (plus_constant): No special handling for LO_SUM. It is
+ not valid to add a constant to a term with LO_SUM, since the
+ constant may need to be added to the high bits that form the sum,
+ and those high bits are not readily available.
+ * explow.c (plus_constant_for_output): Same as `plus_constant'
+ except that we do allow adding constants to LO_SUM terms. This
+ function works only in special cases such as for
+ `adj_offsettable_operand' and `offsettable_address_p'.
+
+ * emit-rtl.c: Declare reg_cc0_rtx which is like cc0_rtx, but
+ is a register instead of a special form. reg_cc0_rtx should
+ be used when representing the condition code register on a
+ machine where condition codes are only set if explicitly set.
+ For machines which allow arbitrary registers to be used as
+ condition code registers (such as the MIPS and 88k), normal
+ pseudo registers should be used instead.
+ * emit-rtl.c (next_cc0_user,prev_cc0_setter): Conditionalized
+ on HAVE_cc0.
+ * emit-rtl.c (find_cc): New function. Given INSN, returns
+ the rtx of what functions as the condition code register for
+ INSN. On machines which use cc0_rtx, this is always cc0_rtx.
+ On machines which have a dedicated register for cc0, this is
+ that register. On machines which allocate pseudos for holding
+ condition codes, this is the pseudo found in a REG_CC0 note.
+ Otherwise, this function returns 0.
+ * emit-rtl.c (init_emit_once): Allocate `reg_cc0_rtx' if
+ CC0_REGNUM is defined.
+
+ * cse.c (make_regs_equiv): Don't consider making a reg
+ equivalent to another reg whose class is NO_REGS.
+ * cse.c (canon_reg): Don't canonicalize a register to
+ one whose class is NO_REGS.
+ * cse.c (fold_rtx): Conditionalize code for handling cc0_rtx
+ with HAVE_cc0.
+ * cse.c (predecide_loop_entry): Generalize code to use either
+ a register or cc0_rtx.
+ * cse.c (cse_insn): Conditionalize code for handling cc0_rtx
+ with HAVE_cc0.
+
+ * combine.c (combine_instructions,try_combine,subst):
+ Conditionalize code handling cc0_rtx with HAVE_cc0.
+ * combine.c (simplify_set_cc0_and): Abort if HAVE_cc0 is not
+ defined.
+ * combine.c (try_distrib): Add break at end of switch cases. It is
+ dangerous to leave the last cases of a switch statement to fall
+ through since new cases added after will get fallen into.
+
+ * recog.c (validate_change): Always succeed for an asm insn,
+ since recog always fails to recognize asm insns. This is
+ needed for virtual register instantiation in asm insns.
+
+ * cse.c (cse_main): When following jumps, notice whether a
+ particular basic block causes CSE_JUMPS_ALTERED to become set. When
+ this happens, repeat the scan.
+ * cse.c (refers_to_mem_p): Changed parameter name REG to BASE,
+ which is more accurate. Also, taught it how to cope with
+ LO_SUM rtl constructs.
+
+Wed Oct 24 15:36:12 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * calls.c (store_one_arg): Accept additional arg, FNDECL.
+ Don't save argument area if it is within the REG_PARM_STACK_SPACE
+ area, but mark the area in use.
+ (expand_call): If ACCUMULATE_OUTGOING_ARGS and REG_PARM_STACK_SPACE,
+ treat the stack area for the registers as be clobbered by the called
+ routine (e.g., if it was compiled without -O) and save and restore
+ it if it was previously used for arguments in a similar manner to
+ the remainder of the argument area (done by store_one_arg).
+
+ * calls.c (expand_call): Support new description macro,
+ STACK_PARMS_IN_REG_PARM_AREA.
+ * function.c (assign_parms): Likewise.
+
+Wed Oct 24 12:47:21 1990 Richard Stallman (rms at mole.ai.mit.edu)
+
+ * c-typeck.c (build_array_ref): Use main variant for value type.
+
+ * genoutput.c (output_prologue): Let SEPARATE_AUX_OUTPUT
+ cause aux-output.c not to be included.
+ Makefile.in (aux-output2.c): Copy aux-output.c and then compile it.
+
+ * reload.c (subst_reg_equivs): Treat HIGH like other constants.
+
+ * reload.c (push_reload): When testing hard reg for validity,
+ test subsequent regs only against class, not for HARD_REGNO_MODE_OK.
+
+Tue Oct 23 22:49:33 1990 Richard Stallman (rms at mole.ai.mit.edu)
+
+ * cccp.c (collect_expansion): Skip ## at start after the error.
+

+
+Tue Oct 23 22:40:33 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * romp.md (store{s,h,q}i pattern): Allow "b" for clobbered pseudo

+
+Tue Oct 23 20:35:13 1990 Richard Stallman (rms at mole.ai.mit.edu)

+Mon Oct 22 12:27:08 1990 Richard Stallman (rms at mole.ai.mit.edu)
+
+ * cccp.c (rescan): In the loop that handles numbers, discard \newline.
+ Also make `..' terminate a preprocessing number.
+
+ * Makefile.in (tmpgnulib, stamp-gnulib2): Do `set -e'.
+
+ * gcc.c (default_compilers): Give __GNUC__ value 2.
+ Don't define it for .S files.
+
+Mon Oct 22 07:33:42 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * optabs.c (emit_indirect_jump): New function; now checks predicate
+ of indirect_jump.
+ * stmt.c (expand_computed_goto, expand_goto): Use new function instead
+ of directly emitting indirect jump.
+
+ * flow.c (mark_set_1): Make LOG_LINKS for hard registers.
+ * combine.c (subst): Make new macro COMBINE_RTX_EQUAL_P which
+ considers things equal if they are the identical RTX or the same
+ register with the same mode; use to see if something changed and
+ if we have a match.
+
+ * cccp.c (S_ISREG): Use argument instead of global.
+ (main): Correct sense of S_ISREG usage.
+ (check_precompiled): Use S_ISREG.
+
+ * flow.c (mark_used_regs): Don't allow reg_next_use to point to
+ a NOTE; either point it to replacement insn or invalidate it.
+
+Mon Oct 22 00:13:12 1990 Richard Stallman (rms at mole.ai.mit.edu)
+
+ * c-parse.y (xdecls): No warning unless -pedantic.
+
+Sun Oct 21 17:49:24 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * genattrtab.c (cc0_rtx): Define, referenced in rtlanal.c.
+
+ * jump.c (jump_optimize): Remove code that depends on changes to
+ emit_store_flag that haven't been made yet.
+
+ * expmed.c (extract_bit_field): Correctly check for bitfield
+ completely filling a mode.
+
+ * out-romp.c (output_epilogue): Correctly write number of words of
+ arguments into trace table.
+
+ * calls.c (store_one_arg): Fix error in change of Oct 19th.
+
+ * reorg.c (mark_target_live_regs): Revert back to old behavior
+ of scanning all insns, even those in delay slots.
+ (fill_simple_delay_slots): Need only call update_block if we move
+ an insn across a label.
+
+ * Makefile.in (LIBFUNCS): Use consistent naming convention for
+ comparison routines; gnulib.c was always correct.
+
+ * function.c (assign_parms): Don't overwrite DECL_INCOMING_RTL when
+ we are called for the second time.
+
+ * integrate.c (initialize_for_inline): Don't make a new return label
+ here; the maximum label number has already been computed.
+ (save_for_inline_copying, save_for_inline_no_copy): Do it here instead.
+
+ * reload.c (find_reloads_address): For indirect address where the
+ underlying address is also invalid, ensure that we substitute into
+ the MEM that we will use.
+
+Sun Oct 21 14:12:47 1990 Richard Stallman (rms at mole.ai.mit.edu)
+
+ * reload.c (find_equiv_regs): Reject reg that overlaps goal.

+
+ * expr.c (expand_builtin): Delete __builtin_varargs.
+ (EXPAND_BUILTIN_SAVEREGS): New macro says how to do __builtin_saveregs.
+
+ * calls.c (expand_call): No "can't inline" warning if -fno-inline.
+
+ * stddef.h: Add missing #endif.
+
+Sat Oct 20 14:33:14 1990 Richard Stallman (rms at mole.ai.mit.edu)
+
+ * function.c (round_trampoline_addr): New function.
+ (trampoline_address): Use that.
+
+Fri Oct 19 15:13:31 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * calls.c (store_one_arg): Don't mark stack area used until after
+ we have written into it; if we do it before, the restore might
+ clobber a function result being put into that stack area.
+
+ * objc-actions.c (print_lang_statistics): Add empty function.
+
+ * recog.c (inequality_comparisons_p): Deleted from here.

+
+Fri Oct 19 14:49:26 1990 Michael Tiemann (tiemann at cygnus.com)
+
+ * sdbout.c (sdbout_symbol): If a variable belongs to an inline
+ function, the decl's rtl may not be rewritten by alter_reg. So if
+ we have a variable allocated to a pseudo, just get the hard register
+ number from `reg_renumber'. ?? But I thought that COFF was so
+ losing that it was decided one could not represent debug info for
+ inline functions in COFF.
+
+Fri Oct 19 13:21:25 1990 Richard Stallman (rms at mole.ai.mit.edu)
+
+ * fold-const.c (split_tree): Use NEGATE_EXPR to negate *conp.
+
+Fri Oct 19 00:15:21 1990 Michael Tiemann (tiemann at cygnus.com)
+
+ * version.c: Bumped to 1.90.03.
+
+ * tree.c: Added facility for gathering statistics on the number of
+ tree nodes allocated and the size in bytes they occupy. The
+ statistics are by tree_node_kind, which is almost like using the
+ tree code letter, but has more resolution for dealing with different
+ kinds of `x' nodes. The facility is enabled by compiling the
+ compiler with -DGATHER_STATISTICS and using the -fstats flag.
+
+ * expr.c (do_tablejump): Emit a BARRIER after the jump that performs
+ the tablejump.
+
+ * cplus-typeck.c (c_expand_return): Rewritten so that the function
+ value return register is not used except as a target of the function
+ return value.
+
+ * cplus-tree.c (build_cplus_new): New argument WITH_CLEANUP_P
+ controls whether this functino should build its result with a
+ cleanup or not. All callers changed.
+
+ * cplus-lex.c: File updated to latest changes to c-parse.y's lexical
+ analyzer.
+
+ * cplus-except.c (cplus_expand_raise): New parameter FOR_RERAISE
+ is used to control whether to output extra gotos or not. When
+ nonzero, the compiler can avoid writing out the extra gotos that are
+ otherwise needed to avoid warning messages.
+
+ * cplus-decl2.c (flag_short_double): Add support for this option.
+
+ * cplus-decl.c (finish_function): Always cause returns to jump to
+ the return label. This allows -Wreturn to give meaningful error
+ messages.
+
+ * jump.c (invert_exp): Make this non-static.
+ (jump_optimize): Reorganization and simplification of main inner
+ loop. Comments added explaining what the optimizers are looking
+ for. New optimization added that optimizes for consecutive testing
+ of an inequality test followed by an equality test (or vice-versa).
+ Changes made to accommodate reorg.c on Sparc. Code for
+ cross-jumping return statements was previously dead in this
+ function; as a result of the reorganization, it is now live.
+ (find_cross_jump): Added temporary variable PREV1 to hold return
+ value of `prev_nonnote_insn' instead of calling the function 3 times
+ in a row. Also changed so that USE or CLOBBERS are not cross-jumped
+ unless some real insns are also cross-jumped. This helps reorg.
+ (redirect_jump): Fixed a return that returned no value so that it
+ returns 1.
+ (rtx_renumbered_equal_p): Test that reg_renumber is nonzero before
+ using it. We may want to call this function earlier than by the
+ time that array has been initialized.
+
+ * integrate.c (save_for_inline_{copying,nocopy}): New functions to
+ replace `save_for_inline'. save_for_inline_copying saves the rtl
+ for inline functions by copying the rtl to the
+ maybepermanent_obstack. It is called when the rtl of the current
+ function is going to be compiled immediately.
+ save_for_inline_nocopy takes advantage of the fact that inline
+ function rtl is already allocated to the maybepermanent_obstack, and
+ need therefore not be copied if it's not going to be modified by the
+ compiler (such as by `rest_of_compilation').
+ ({initialize_for,finish}_inline): New helper routines for
+ save_for_inline_... functions.
+ (note_modified_parmregs): Function called by `mark_stores' to note
+ whether parameters are assigned to in the body of an inline
+ function.
+ New interface, integrate.h, provides declarations for functions used
+ by other routines that might want to copy chunks of rtl.
+ ({save,try}_constants): Now global (for integrate.h).
+ (mark_stores): Ditto.
+ (try_fold_condition): Ditto.
+
+ * dbxout.c (dbxout_symbol): If a variable belongs to an inline
+ function, the decl's rtl may not be rewritten by alter_reg. So if
+ we have a variable allocated to a pseudo, just get the hard register
+ number from `reg_renumber'.
+
+ * varasm.c (output_const_pool): No longer static.
+ (assemble_variable): Do output debugging information for global
+ register variables. GDB does the right thing for global register
+ variables.
+
+ * toplev.c: New flag `warn_inline' for warning when a function
+ declared inline was not in fact inlined. Also, new flag
+ `flag_no_inline' which disables function inlining, but retains
+ other properties of inline functions (such as lazy compilation
+ and write-only-if-needed).
+ * toplev.c (compile_file): Changed logic for inline function
+ handling to work with `warn_inline' and `flag_no_inline'.
+ Also modified to call `save_for_inline_nocopy' when insns are to be
+ saved but not immediately compiled.
+
+ * function.c (instantiate_decls): If instantiating a function
+ which was saved for inline expansion, preserve the rtl created
+ by the instantiation as well.
+
+ * flags.h (flag_no_inline): New flag; if nonzero, then no
+ calls are inlined, regardless of their declaration. We still
+ save the insns for these functions in DECL_SAVED_INSNS so that
+ the functions need not be written if they are never called.
+
+ * calls.c (expand_call): If `flag_no_inline' is set, don't
+ inline the call, regardless of whether it was declared inline
+ or not.
+
+Thu Oct 18 13:10:26 1990 Richard Stallman (rms at mole.ai.mit.edu)
+
+ * rtl.def (CODE_LABEL): Add new string field.
+ * rtl.h (LABEL_NAME): Define macro for access.
+ * emit-rtl.c (gen_label_rtx): Initialize it to 0.
+ * stmt.c (expand_label): Store proper name of label.
+ * final.c (final_scan_insn): Call sdbout_label.
+
+ * tree.h (built_in_function): Add BUILT_IN_VARARGS.
+ * c-decl.c (init_decl_processing): Declare __builtin_varargs.
+ * expr.c (expand_builtin): Generate code for it.
+ Uses new macro EXPAND_BUILTIN_VARARGS.
+
+ * sdbout.c (SDB_IS_FAKE): Macro deleted.
+ (MAKE_LINE_SAFE): New macro.
+ (sdbout_begin_block, sdbout_end_block, sdbout_end_function): Use it.
+ (sdbout_one_type): Delete spurious second arg in all callers.
+ (sdbout_types, sdbout_end_function):
+ Use sdbout_dequeue_anonymous_types.
+ (sdbout_label): New function.
+
+ * expr.h (FUNCTION_ARG_BOUNDARY): Default is now PARM_BOUNDARY.
+
+ * gvarargs.h, va-*.h (va_dcl):
+ Add ellipsis so current_function_varargs is set.
+
+ * jump.c (jump_optimize): Exit push-optimize loop at end of insns.
+
+Thu Oct 18 07:09:06 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * reorg.c: Major reorganization. Many special cases have been moved
+ into more general code and an overall restructuring has been done.
+ Numerous bugs have been fixed. Highlights:
+ (dbr_schedule): First make list of all insns needing filling. Then
+ iterate for two passes. In each pass, try two methods of filling
+ delay slots, then do some canonicalizations, which may create more
+ insns to fill.
+ (fill_simple_delay_slots): Now uses list of insns that need filling,
+ rather than making such a list.
+ Enhance code that finds insns when code paths merge to allow multiple
+ uses of the label as long as all uses are in the skipped code.
+ (struct resource): Notice volatile memrefs.
+ (stop_search_p): Allow option to continue when label is reached.
+ (find_end_label, make_return_insns): New functions; when we have a
+ filled branch that is really a RETURN, first convert it to a jump
+ to a return label and then later see if the insns in the delay slots
+ are also valid for a RETURN.
+ (mostly_true_jump): Test for branch to loop beginning rather than
+ branch at end of loop. Also, conditional return insns predict false.
+ (own_thread_p): New function to replace fall_through_to_p.
+ (try_merge_delay_insns): Only support merging insns already in an
+ insns delay list.
+ (get_branch_condition, condition_dominates_p): New functions.
+ (steal_delay_list_from_{target,fallthrough}): New functions to
+ replace steal_delay_list.
+ (redundant_insn_p): New function.
+ (update_block, mark_target_live_regs, dbr_schedule): When moving
+ an insn not at the front of the basic block to a delay slot,
+ leave a "ghost" USE so that we can track things livened and killed.
+ (fill_slots_from_thread): Eliminate use of static vars for number
+ of slots to fill and already filled.
+ Try to modify an insn that follows a register-register copy to use
+ the original register; this may create a delay-slot opportunity.
+ (try_hoist_target{,_1}): Deleted.
+ (relax_delay_slots): Rewritten to just perform canonicalizations
+ previously done elsewhere. No actual delay slot filling is done
+ here. Any new delay slots created will hopefully be filled in the
+ next pass around the loop in dbr_schedule.
+
+ * expr.c (emit_push_insn): Don't try to compute a SUBREG of a
+ hard register in a non-integer mode when pushing a "partial" arg.
+
+ * recog.c (validate_change, apply_change_group): After reload, ensure
+ that operands meet the constraints by calling constrain_operands.
+ (validate_replace_rtx_1): Consider two rtx equal if they refer to
+ the same register.
+
+ * jump.c (jump_optimize): Extend change of Oct 16th to handle
+ the other usage of find_equiv_reg; remove invalid death notes there.
+
+ * rs6000.md, tm-rs6000.h, out-rs6000.c, xm-rs6000.h, make-rs6000:
+ New files.
+
+ * out-a29k.c (extract_subword): Use gen_{high,low}part from
+ an FP CONST_DOUBLE if host and target float formats are the same
+ or REAL_IS_NOT_DOUBLE.
+
+ * out-romp.c (output_fpop, output_fpops): Provide fr0 as a scratch
+ register unless it is used in the insn.
+
+ * romp.md: In combined set CC0 and move, optimize case where move
+ is nop.
+ (DF moves): Fix typo in generation of `get' insn.
+ Don't split if input is CONST_DOUBLE because we can't easily
+ generate the proper constants.
+ (call patterns): Copy data area address via a pseudo to allow
+ better CSE'ing.
+
+ * tm-romp.h (RTX_COSTS): Memory is expensive, except for a reference
+ to our own data area, which is very cheap.
+ (ADDRESS_COST): References to the constant pool are as cheap as
+ register + offset, since that's what it will be.
+
+ * emit-rtl.c (gen_{low,high}part): Can often extract word from FP
+ CONST_DOUBLE when host and target floating formats agree.
+ (add_insn_after): No longer static.
+
+ * reload1.c (reg_equiv_memory_loc): Renamed from reg_equiv_stack_slot
+ and now static.
+ (reload): If have equivalence with constant that is not a legitimate
+ constant operand, force it into memory and handle this as an
+ equivalence to memory.
+ * reload.h (reg_equiv_stack_loc): Deleted.
+
+Wed Oct 17 20:50:58 1990 Richard Stallman (rms at mole.ai.mit.edu)
+
+ * gcc.c, cccp.c (main): Use TARGET_VERSION if -v.

+
+ * gcc.c (do_spec_1): Null-terminate error message.
+

+ This happens for vars from the parms of inline functions.
+ * dbxout.c (dbxout_symbol): Likewise.
+
+ * genattr.c (fancy_abort): New function, as in gen*.c.
+

+
+ * Makefile.in (tmpgnulib): Fix typos handling LIBFUNCS_EXTRA.
+
+ * cccp.c (handle_directive): Turn on code to handle # LINENUM,

+ (finish_struct): Don't do that here.
+
+ * fixincludes (CTRL): Don't put quotes around a quote.

+
+Tue Oct 9 14:16:37 1990 Richard Stallman (rms at mole.ai.mit.edu)
+
+ * expmed.c (extract_bit_field): Typo; section for extv used extzv.

+
+Tue Oct 9 06:18:38 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * cse.c (fold_rtx): Call find_best_addr before seeing if we know
+ what is located at that address.
+ Don't try to return the contents of an ADDR_DIFF_VEC table; we have
+ no simple way of representing it.
+ (cse_insn): Detect SRC == DEST even when DEST is not the canonicalized
+ form of the value represented by SRC.
+
+ * loop.c (scan_loop): Don't set THRESHOLD until LOOP_HAS_CALL
+ has been set.
+ (struct induction): Add field MEM_MODE.
+ (find_mem_givs, combine_givs_p): Record mode used to access memory
+ when making DEST_ADDR giv and use it to test validity of

+ Now returns success/failure indication like redirect_jump.
+ * rtl.h (delete_jump): Define.
+
+ * calls.c (store_one_arg): Don't expand a `partial' arg into

+
+Thu Oct 4 05:06:02 1990 Michael Tiemann (tiemann at cygnus.com)
+
+ * gcc.c (default_compilers): Define __OPTIMIZE__ for %{O*}, not just
+ %{O}. This permits the use of -O2, -O3, etc., with predictable
+ results.
+
+ * expr.c (expand_expr): Do not build new cleanups for
+ TARGET_EXPRs. Their cleanups are now handled entirely by the
+ language-specific code that causes them to be generated.
+
+ * function.c ({push,pop}_temp_slots): Do not change
+ temp_slot_level if within a sequence. GNU C++ must be able to
+ emit a sequence it is building anywhere at the level the sequence
+ was initiated. If the level is changed when building a sequence,
+ temporaries could be unwittingly shared.
+

+ volatile, but also make the field or variable so.
+
+ * c-decl.c (grokdeclarator): Turn off the warning for const or volatile
+ function type when making an array. It was useless.
+
+Fri Aug 31 16:26:40 1990 Richard Stallman (rms at mole.ai.mit.edu)
+

+
+Sun Aug 26 23:10:10 1990 Richard Stallman (rms at mole.ai.mit.edu)
+

+
+ * tm-att386.h (asm_output_common): Use SIZE, not ROUNDED.
+
+Sat Aug 25 17:17:27 1990 Richard Stallman (rms at mole.ai.mit.edu)
+

+
+ * final.c (alter_cond): Handle CC_INVERTED.
+
+ * conditions.h (CC_INVERTED): New flag indicating that the condition
+ tested leaves the falgs set opposite to the condition tested. This
+ is unsafe for IEEE floating point operations, but useful for integer
+ operations which can combine with condition-code setting operations.
+
+ * c-parse.y (position_after_white_space): New function. Skips
+ all of the whitespace at the current location in the input
+ file, taking NEXTCHAR into account. Changed all callers of
+ `skip_white_space' in grammar to use this function instead.
+
+ * genrecog.c (main): Generate code which is more easily optimized by
+ GCC's cse. In particular, start each recognizer with the address of
+ `recog_operands' in a register.
+
+ * reload.c (combine_reloads): Can only combine reloads if the
+ register we find can hold the entire output reload (i.e., SFmode

+ * optabs.c (have_sub2_insn): Fixed typo.
+ * combine.c (combine_instructions): Fixed typo in comment.
+
+ * function.c (expand_function_end): Emit a barrier after a RETURN
+ jump.
+
+ * Added diffs for new instruction scheduling code.
+ * emit-rtl.c (try_split): Moved here from reorg.c and made
+ public. Both instruction scheduling and delayed branch
+ filling now use the same code to split insns.
+ * flags.h: Add new flags FLAG_SCHEDULE_INSNS for instruction
+ scheduling before register allocation and
+ FLAG_SCHEDULE_INSNS_AFTER_RELOAD for insn scheduling after
+ register allocation.
+ * recog.c (constrain_operands): Recognize pseudo registers as
+ registers for the purpose of insn constraint matching before
+ register allocation. Otherwise, the insn scheduler assumes
+ the operands will be memory, which is usually wrong (and
+ causes it to build bad schedules).
+ * sched.c (order_calls): New function. For two CALL_INSNS in
+ the rtl chain, we set up a constraint that the second
+ CALL_INSN may not be scheduled to run before the first.
+ (sched_analyze_*): Three kinds of dependencies (true, anti,
+ and output) constrain the order in which insns can be
+ rearranged and still preserve their execution semantics.
+ We now handle dependencies for pseudo and hard register usage
+ and for memory usage in these functions.
+ (launch_links): The ordering of which newly ready insns to
+ execute is now preserved according to their `priority' in the
+ insn chain, and no longer on their order in the dependency
+ list from which they were launched.
+ (schedule_block): Removed support for trying to schedule insns
+ taking branch delays into account. Reorg.c should be hacked
+ to understand which insns to pull into delay slots and which
+ insns to leave alone.
+ (schedule_block): (Re-)compute all register life information here.
+ No longer dependent on flow to keep `basic_block_live_at_end'
+ allocated.
+ (schedule_insns): Recompute LABEL->BASIC BLOCK mapping, so we
+ can compute register life information.
+ * rtl.c (add_dependence): New function to add and remove insn
+ dependencies. If an insn (I2) must execute after another
+ (I1), we add an INSN_LIST containing I1 to I2's LOG_LINKS.
+ If such an INSN_LIST is already in I2's LOG_LINKS, we don't
+ add a second.
+ (remove_dependence): Similar, but removes dependencies. May
+ not actually be needed.
+ * toplev.c (compile_file,rest_of_compilation): Added code for
+ dumping info about insn scheduling.
+
+Fri Aug 24 17:24:03 1990 Richard Stallman (rms at mole.ai.mit.edu)
+
+ * Implement `aligned (INTEGER)' attribute for real.

+ (merge_component_references): Correctly test for mutually exclusive
+ conditions.
+
+Thu Aug 23 14:56:44 1990 Richard Stallman (rms at mole.ai.mit.edu)
+

+ * expr.c (emit_library_call): Our subset of calling sequence for
+ library routines does not include multiple registers for an arg.

+ (merge_component_references): Put rewritten version here.
+ This fixes bugs in the way that comparisons with non-equal
+ constants (!p->a && p->b) are handled and in endianness checking.
+ Also accepts more general comparisons, and, in particular, its
+ own output so more than a pair of operations can be merged.
+ (fold): Call it for TRUTH_{AND*,OR*}_EXPR.
+
+ * tree.def (BIT_FIELD_REF): New tree code.
+ * expr.c (get_inner_reference): Support BIT_FIELD_REF.
+ If bitfield is a complete mode-sized unit, return that mode; if it

+ (expand_assignment): Check for BIT_FIELD_REF.
+ Use mode returned from get_inner_reference to see if bit field.
+ (store_constructor): Likewise.
+ (store_field): Don't pass arg BIT_FIELD; use MODE == VOIDmode

+ (expand_expr, case BIT_FIELD_REF): New case. Handled same as

+ Use mode returned from get_inner_reference rather than DECL_BIT_FIELD.
+ (expand_increment): Must stabilize BIT_FIELD_REF.

+ (fold_convert): Accept second argument that is item being
+ converted to ensure that NOPs have been stripped.
+ (operand_equal_p): Return 0 if either operand has side effects.

+ specifically, compare the operands of simple TREE_CODEs.
+ (omit_one_operand, distribute_bit_expr): New functions.
+ (make_bit_field_ref, optimize_bit_field_compare): Likewise.
+ (fold): Remove LOSES; now done explicitly or by calling
+ omit_one_operand. Some previous uses weren't needed.
+ Try to fold any COND_EXPRs and some COMPOUND_EXPRs we make.
+ Remove pair of NEGATE_EXPRs and BIT_NOT_EXPRs.
+ Convert "- (a - b)" to "b - a" for non-floating-point.
+ ABS_EXPR applied to ABS_EXPR or NEGATE_EXPR is ABS_EXPR of inner arg.
+ Convert "a + (-b)" to "a - b" and "a - (-b)" to "a + b".
+ If adding ANDs with constants that have no bits, in common, try
+ bitwise-or, since we may then be able to distribute the operation,
+ e.g., (a & 7) + (a & 0x70) -> a & 0x77.
+ Add missing last arg to operand_equal_p call.
+ Call distribute_bit_expr for BIT_AND_EXPR and BIT_IOR_EXPR.
+ Exclusive-or with all ones is bit negation.
+ If second arg of BIT_AND_TC_EXPR is constant, convert to BIT_AND_EXPR.
+ Handle TRUTH_NOT_EXPR by calling invert_truthvalue.

+
+ * optabs.c (expand_twoval_binop): Fix typo.

+Sun Aug 12 21:42:55 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * expr.c (expand_expr, case COND_EXPR): Don't abort if first arg of

+
+Fri Aug 10 14:14:08 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * recog.c (indirect_operand): Modes need not agree if MODE == VOIDmode;

+Wed Aug 8 14:00:26 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * out-romp.c: Don't include hard-reg-set; already in insn-output.c.
+
+ * explow.c: insn-flags.h is needed to see if "probe" insn exists.

+Sun Aug 5 00:04:08 1990 Michael Tiemann (tiemann at cygnus.com)
+
+ * cplus-decl2.c (grokfield): It is no longer legal to specify

+ declaration. Dealing with default initializers is basically
+ impossible.
+
+ * cplus-init.c (build_delete): Don't wrap `addr' in a SAVE_EXPR
+ until it is in fact an address. This allows us to call
+ destructors on the return values of function calls.
+
+ * cplus-typeck.c (commontype): Fixed bug in OFFSET_TYPE case which
+ led to infinite recursion (since we did not reduce the types
+ before we recursed).
+
+ * cplus-lex.c (check_newline): Make `#pragma implementation' more
+ forgiving.
+
+ * cplus-init.c (expand_aggr_init): Changed Jan 20th change so that

+ at all whether INIT was from a GNU constructor expression or not.
+
+ * cplus-typeck.c (build_modify_expr_1): Don't return
+ `error_mark_node' unless there really was an error. If there is

+
+ * cplus-decl.c (finish_decl): Emit a line-number note to give
+ users a chance to set a breakpoint before the initialization of an
+ object takes place.
+
+ * cplus-class.c (build_method_call): If the function we get is not
+ directly from the object we have, call `convert_pointer_to' if the
+ object uses multiple inheritance or virtual baseclasses.
+
+ * cplus-typeck.c (build_binary_op_nodefault): Don't call
+ `convert_to_pointer' with an argument that might be

+ in RESULT_DECLs as well.
+
+ * cplus-init.c (build_vec_delete): Don't forget to deallocate the

+ gives to its AUTO_DELETE parameter.
+
+Sat Aug 4 22:08:44 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * jump.c (find_cross_jump): Use prev_nonnone_insn.
+ Don't cross-jump into the middle of a USE-CALL_INSN-CLOBBER
+ block; doing so can confuse reorg.c.
+
+ * optabs.c (expand_binop, expand_binop, expand_twoval_binop):
+ If predicate doesn't match, ensure that operand is in a pseudo
+ register. Current code assumes that any register will suffice,
+ but an insn may want to reject certain hard registers.
+ (expand_unop, emit_unop_insn, emit_cmp_insn): Likewise.
+
+Sat Aug 4 15:29:09 1990 Michael Tiemann (rms at sugar-bombs.ai.mit.edu)
+
+ * function.c (assign_parms): For parms passed by reference,
+ make the memory object's mode agree with the parm's original
+ type mode.
+ * calls.c (expand_call): Fixed braino in building argument
+ reference when FUNCTION_ARG_PASS_BY_REFERENCE is defined.
+
+ * varasm.c (assemble_variable): Hack our way around the problem
+ that static class members look like initialized variables for the
+ purposes of establishing FIRST_GLOBAL_OBJECT_NAME.
+
+ * cplus-lex.c (reinit_parse_for_method): Give error message for
+ common mistake of forgetting the function body.
+
+ * cplus-typeck.c (build_component_ref): Make better error message
+ when field is not found.
+
+ * cplus-class.c (finish_struct): TYPE_GETS_*_INIT_REF comes from
+ members as well.
+
+ * cplus-typeck.c (c_expand_return): Give warning about returning
+ non-lvalues that come from functional casts.
+
+ * cplus-search.c (get_base_distance): Changed to follow leftmost
+ path only when PARENT == TYPE_MAIN_VARIANT (PARENT).
+
+ * cplus-class.c (modify_vtable_entries): Call get_base_distance
+ with 0 path_ptr, since we do not appear to use the path computed.
+
+Fri Aug 3 07:37:30 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * final.c (leaf_function_p): Delete line advertently retained
+ after change of July 29.
+
+ * reorg.c (optimize_skip, try_hoist_target): Don't invert jump
+ unless can_reverse_comparison_p says it is OK. Use invert_jump
+ to do it.
+ (fill_simple_delay_slots): Another way flow of control can merge is
+ for two insns to jump to the same place; try to get insns from there.
+ (mostly_true_jump): Return 2 for a jump very likely to be true (the
+ branch back to the start of a loop).
+ (fill_slots_from_thread): Accept new arg LIKELY. If true, see if can
+ put increment in delay slot and undo it after the end of the loop.
+ (fill_eager_delay_slots): Pass new arg to fill_slots_from_thread.
+ If previous insn is conditional jump that also didn't get a delay
+ slot, see if swapping targets helps.
+
+Fri Aug 3 00:18:35 1990 Richard Stallman (rms at sugar-bombs.ai.mit.edu)
+
+ * cccp.c (MAKE_POS): Avoid constant of uncertain signedness.

+
+Thu Aug 2 17:44:59 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * output.h (current_function_return_rtx): Add new variable.
+ * function.h (return_rtx): Likewise.
+ * function.c (push_function_context, pop_function_context): Save
+ and restore current_function_return_rtx.
+ (assign_parms, expand_function_start): Set current_function_return_rtx
+ to what is put in DECL_RTL (DECL_RESULT (current_function_decl)).
+ * reorg.c: No longer uses tree.h.
+ (dbr_schedule): Get result RTL from current_function_return_rtx instead
+ of reading it from current_function_decl.
+ * Makefile.in (reorg.o): No longer depends on TREE_H.
+
+ * cse.c (remove_invalid_refs): Only invalidate an entry if it
+ references the actual register, not merely something sharing its
+ quantity.
+ (cse_insn): Don't abort if SRC and SRC_EQUIV map to different
+ hash classes. Merge them instead.
+
+ * romp.md (mulsi3): Emit call to lmul$$ as a regular insn
+ rather than a CALL_INSN.
+ (divsi3, modsi3, udivsi3, umodsi3, call_libfcn): Deleted.
+ (divmodsi4, udivmodsi4): New patterns to call ldiv$$ and uldiv$$
+ as a normal insn to allow CSE'ing of MOD with DIV.
+
+Wed Aug 1 21:56:08 1990 Richard Stallman (rms at sugar-bombs.ai.mit.edu)
+
+ * c-parse.y (yylex): Don't warn about non-decimal unsigned by default
+ if `u' was specified. Add similar warning for long and long long.
+
+Tue Jul 31 23:31:46 1990 Richard Stallman (rms at sugar-bombs.ai.mit.edu)
+
+ * tm-encore.h (FUNCTION_PROFILER): Override, putting `.' in label.

+ (convert_arguments): Include arg number in incomplete type warning.
+
+Mon Jul 30 07:38:55 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * jump.c (invert_jump): Don't do anything with labels if NLABEL
+ equals JUMP_LABEL.
+ (redirect_jump): Don't try to reference LABEL_NUSES if olabel is
+ zero (meaning this is a return insn).
+ (redirect_exp): Handle case of converting return to jump to
+ label.
+
+ * dbxout.c (dbxout_parms): Allow parameter at zero offset from
+ AP to be represented as (MEM (REG ...)).
+ * sdbout.c (sdbout_parms): Likewise.
+
+Sun Jul 29 22:51:00 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * optabs.c (expand_twoval_binop_convert): Deleted.
+ (expand_twoval_binop): Rework to be handle predicates, modes, and
+ failures in a manner consistent with expand_binop.
+ Move code from expand_twoval_binop_convert inline and rework to
+ no longer hard-wire SImode and to handle failure.
+
+ * config.gcc: Finish change of July 24th to have make_var_file depend
+ on host machine.
+
+ * jump.c: Now includes insn-flags.h.
+ (jump_optimize): Try to put a RETURN at the end of the function if
+ control flows through to it.
+ JUMP_LABEL can now be zero for a RETURN or conditional RETURN.
+ Try to convert jump to end of function into (possibly conditional)
+ RETURN.
+ Use next_active_insn instead of next_real_insn; these do the same
+ thing prior to reload, after which USE and CLOBBERs don't matter.
+ redirect_jump may now fail so don't set CHANGED if it does.
+ Delete optimization of jump to RETURN; now subsumed by follow_jumps.
+ Reset INSN_CODE if changing conditional jump to unconditional.
+ (cond_jump_p): Conditional RETURN is conditional jump.
+ (follow_jumps): Change argument name to AFTER_RELOAD.
+ If not after reload, do not chain across a USE or CLOBBER.
+ Recognize RETURN insns.
+ (tension_vector_labels): Likewise.
+ (redirect_jump, redirect_exp): If NLABEL is zero, turn JUMP into a
+ (possibly conditional) RETURN; use validate_change to see if such an
+ insn exists.
+ Now returns non-zero if succeeds, 0 otherwise.
+ Unconditional RETURN looks like (RETURN), not (SET (PC) (RETURN)).
+ (thread_jumps): Ignore any type of RETURN insn.
+ * Makefile.in (jump.o): Depends on insn-flags.h.
+ * loop.c (strength_reduce): Don't confuse conditional return with
+ jump to top of loop when LOOP_TOP == 0.
+ * final.c (leaf_function_p): No longer static; no longer takes an arg.
+ (final_start_function): Don't pass START to leaf_function_p.
+ * romp.md (return pattern): Convert to a named pattern.

+
+ * reorg.c (fill_slots_from_thread): Restore inadvertantly deleted

+ and ASM_OUTPUT_SHARED_LOCAL.
+
+ * tm-encore.h (SHARED_SECTION_ASM_OP): New macro.
+ (ASM_OUTPUT_SHARED_COMMON, ASM_OUTPUT_SHARED_LOCAL): New.

+ only if little-endian.
+
+Thu Jul 26 23:19:15 1990 Richard Stallman (rms at sugar-bombs.ai.mit.edu)
+
+ * expmed.c (expand_shift): Consistently call protect_from_queue
+ before doing anything else.
+ Always put operand1 of extzv into a register because it is SImode
+ and we assume that this means a register.
+
+Thu Jul 26 14:18:11 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * varasm.c (assemble_variable): Delete dead code.
+ DATA_ALIGNMENT takes tree and current alignment and gives new
+ alignment for a non-automatic variable of that type.
+ Also apply CONSTANT_ALIGNMENT to the initial value; it now takes
+ the constant and old alignment and gives the new alignment.
+ Adjust DECL_ALIGN to the resulting alignment.
+ Use floor_log2 consistently instead of duplicating its function.
+ (get_or_assign_label): Use CONSTANT_ALIGNMENT instead of DATA_ALIGNMENT
+ and pass type instead of decl.
+ * expr.c (get_pointer_alignment): Rework to: distinguish reliably
+ between expressions giving the address and those giving the item being
+ addressed; use the alignment from the type of the object being
+ pointer to; return 0 if the type is not a pointer; and other
+ miscellaneous changes.
+ (string_constant): Skip CONVERT_EXPR and NON_LVALUE_EXPR as well
+ as NOP_EXPR.
+ (expand_builtin): Allow get_pointer_alignment to fail, in which case
+ we call the actual function.
+ * stmt.c (expand_decl): Set actual alignment obtained into DECL_ALIGN
+ since it may be better aligned than required and get_pointer_alignment
+ can take advantage of this.
+ * tm-gmicro.h, tm-pyr.h, tm.romp-h: Add or replace definitions of
+ CONSTANT_ALIGNMENT to word-align string constants and
+ DATA_ALIGNMENT to word-align character arrarys for builtin memory
+ functions.
+
+ * fold-const.c (rshift_double): Reset carry after each shift of
+ one bit.
+
+ * vax.md (ashrsi3): If right shift by constant, emit as ASHIFTRT.
+ (ashrsi3_const): New pattern to match it.
+ (casel): Delete patterns no longer needed.
+ * cse.c (cse_insn): Remove unneeded part of change of July 23.
+ (fold_rtx): Convert shift with negative constant count to shift in
+ the opposite direction.
+ * combine.c (subst): Likewise.
+
+ * emit-rtl.c (init_emit_once): Initialize arg_pointer_rtx before
+ struct pointer and static chain values in case they want to use it.

+
+ * final.c (final_scan_insn): Align label table to boundary appropriate

+Wed Jul 25 15:06:44 1990 Richard Stallman (rms at sugar-bombs.ai.mit.edu)
+
+ * fixincludes: Handle uses of _IO* followed by spaces.
+ Change redirections for cd when testing that directory exists.
+
+ By Tiemann:
+
+ * emit-rtl.c (next_cc0_user): Handle insns in which cc0
+ is set and used in the same insn.
+
+ * final.c (leaf_function_p): Look inside INSNs which contain
+ a delayed-call sequence.
+ (final_start_function): Test `only_leaf_regs_used' before
+ `leaf_function_p', since that is likely to be faster.
+ (final_scan_insns): Normally we don't have NOTICE_UPDATE_CC
+ take action when processing the path of an annulled branch,
+ since that path does not affect the cc's of the fall-through
+ insns at all. However, we cannot always ignore the effect of
+ the cc's when processing a delayed annulled branch: when the
+ delayed annulled branch follows a label and carries a
+ REG_CC_STATUS note, that note must be processed.
+
+ * genattr.c (main): Generate #defines for annulled branches
+ which are consistent with documentation.
+
+ * reorg.c: Finish recent rework by modifying code specific to
+ machines that have annulling branches.
+
+ * c-common.c (merge_component_comparisons): Previous logic did
+ not handle cases of (A == 1) && (B == 1), (A != 0) && (B != 0),
+ and (A != 1) || (B != 1). Fixed by expanding the logic out
+ longhand and letting the compiler do the proper cross-jumping.
+
+ * tm-vms.h (ASM_OUTPUT_EXTERNAL): Use assemble_name.
+
+ * expr.c (expand_expr): For BIND_EXPR, do the init for all vars.
+
+ * stupid.c: Include flags.h.
+ * genrecog.c (main): Make insn-recog.c include flags.h.
+
+Sun Jul 22 12:04:43 1990 Michael Tiemann (tiemann at cygnus.com)
+
+ * cplus-except.c (cplus_expand_end_except): If the user gives a
+ default handler, the exception is considered caught in that
+ handler.
+ * cplus-parse.y (except_stmts): Rest of fix went here, in DEFAULT
+ case.
+
+ * cplus-decl.c (finish_decl): Don't emit cleanups twice.
+
+ * cplus-class.c (finish_struct_bits): Don't call
+ `fixup_vbase_offsets'.
+ * cplus-tree.c (fixup_vbase_offsets): #if 0 this function.

+
+ * cplus-method.c (prepare_inline): Set DECL_CONTEXT of this

+
+Thu Jul 5 10:44:39 1990 Michael Tiemann (tiemann at cygnus.com)

+ (expand_call, store_one_arg): Save and restore stack slot starting
+ from beginning of slot, not begining location where arg is stored.
+ (store_one_arg): After calling emit_push_insn, argument is really
+ at arg->stack_slot instead of arg->stack because if we want to

+
+ * jump.c (thread_jumps): New function to optimize the case where one
+ conditional jump jumps to another testing the same condition. This

+ introduces new conditional jumps after rearranging loops).
+ (rtx_equal_for_thread_p): cheaply builds equivalences between

+ faster. Also, test the first letter of each string before calling
+ the string comparison function.

+ * stor-layout.c (layout_{record,union}): For loop bodies meant only
+ for FIELD_DECLs, make sure we have a FIELD_DECL before proceeding.
+
+ * stmt.c (expand_end_case): Use ADDR_DIFF_VEC if FLAG_PIC is

+ * genattrtab.c (main): Handle DEFINE_SPLIT.
+
+ * fold-const.c (various places): Use `build1' constructor instead of
+ `build' constructor whenever possible.
+
+ * final.c (final_scan_insn): If we know the status of the condition
+ codes at a particular JUMP_INSN (by dint of the fact that it has a
+ REG_CC_STATUS note), set CC_STATUS to reflect that value.
+ (only_leaf_regs_used): @@ For some reason the frame pointer register
+ is not marked live, even when it is. If FRAME_POINTER_NEEDED is
+ nonzero, set REGS_EVER_LIVE[FRAME_POINTER_REGNUM] to 1.
+
+ * expr.c (emit_library_call): Round ARGS_SIZE.CONSTANT up, not down.
+ Use new macro MAX to accomplish this.
+ (safe_from_p): Don't check that EXP is nonzero. Instead, make
+ caller check (only in one place) that argument to `safe_from_p' is
+ non-zero.
+ (expand_expr): In COND_EXPR case, make sure that the predicate is
+ safe from the two conditions. Lossage occured in a construct of the
+ form (c = c < 0 ? d : -d).
+
+ * explow.c (plus_constant): Handle LO_SUM rtl.
+
+ * c-typeck.c (build_binary_op_nodefault): If optimizing, try merging
+ component refs and/or comparisons into larger operations.

+ COMPONENT_REF operations.
+ (make_merged_ref): Builds custom FIELD_DECLs for accessing multiple

+ (merge_component_comparisons): Optimize COMPONENT_REFs in
+ expressions that look like (x.p == y.p && x.q == y.q) or
+ (x.p != y.p || x.q != y.q). Also optimize (x.p == c1 && x.q == c2),
+ where C1 and C2 are known constants.
+
+ * c-lang.c (print_lang_statistics): Added new hook function.
+ Currently does nothing for C.
+
+ * c-convert.c: Use `build1' constructor instead of `build'

+
+ * cplus-parse.y (operator_name): Recognize `operator,'.
+ (expr): On parsing ',', call `build_x_compound_expr' instead of
+ `build_compound_expr'.
+ (various places): Call `note_decl_list_got_semicolon' instead of

+ of a type.
+ (component_declarator0): Set CURRENT_DECLSPECS from the bitfield
+ type.
+
+ * cplus-method.c (hack_wrapper): Rename parameter TYPE to CNAME,

+ declarations should be considered as having "gotten a semicolon".

+ TREE_HAS_CONSTRUCTOR where appropriate.
+
+ * cplus-expr.c (cplus_expand_expr): Use `emit_block_move' to copy
+ data from RETURN_TARGET to CALL_TARGET in case they do not line up
+ normally.
+
+ * cplus-decl2.c (finish_file): No need to call `build_vbase_delete'
+ on top-level objects anymore, since destructors now do the right
+ thing.
+
+ * cplus-decl.c (finish_function): Implement new destructor
+ mechanism: destroy virtual baseclass objects if (in$charge & 2) is
+ nonzero. Deallocate if (in$charge & 1) is nonzero.
+
+ * cplus-cvt.c (build_up_reference): Use TREE_HAS_CONSTRUCTOR, not
+ TYPE_HAS_CONSTRUCTOR on non-TYPE tree nodes.
+ (build_up_reference): Only build up references between compatible

+ For ADDR_EXPR's, don't hash address of SYMBOL_REF. Only use

+
+ * reload1.c (reload, init_reload): Moved call to

+
+ * reload1.c (modes_equiv_for_class_p): Only fail if registers in
+ CLASS that can hold ALLOCATE_MODE can't also hold OTHER_MODE. Do

+ (reload): Change call to modes_equiv_for_class_p to match new
+ semantics.
+
+ * combine.c (simplify_shift_const): When simplifying (ashiftrt
+ (ashift inner_const_int) const_int), was checking the wrong number of
+ high order bits of inner_const_int. Also correct typos in comments.
+
+ * c-convert.c (convert_to_integer): Must also check ARG1 for
+ unsignedness, because ARG0 could be a constant when EXPR is a

+ I2DEST if it is referenced by NEWPAT.
+
+ * combine.c (distribute_notes): After converting REG_DEAD notes to

+
+ * stupid.c (stupid_mark_refs): Registers that aren't used must die
+ in the insn after their birth so they conflict with other outputs.
+
+ * vax.md: Replace patterns to convert (and (ashiftxx))
+ into (and (rotatexx)) with the patterns that are actually made
+ by combine.
+ We can allow offsettable addresses for operand 0 and it is not
+ early-clobber.
+
+ * out-rs6000.c (secondary_reload_class): Correctly interpret result of
+ true_regnum.
+
+ * out-rs6000.c (output_toc): Write FP constants in TOC.

+Sat Jun 22 07:24:33 1991 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * cse.c (cse_set_around_loop): Fix typo in call to note_mem_written.
+
+ * emit-rtl.c (reorder_insns): Correctly handle case when AFTER is last
+ insn.
+
+ * expr.c (expand_expr, case COND_EXPR): Correctly handle X ? A : X + 1.
+ Previous change called invert_truthvalue which can modify EXP; we now
+ call it a second time to undo its action if do_store_flag fails.
+
+Sat Jun 22 02:37:59 1991 James Van Artsdalen (james at bigtex.cactus.org)
+
+ * cse.c (cse_set_around_loop): Don't try to initialize an

+
+ * loop.c (loop_number_exit_labels): Expand comment. Mention that

+ immediately after the jump table
+ Remove special-case kludge for ADDR_DIFF_VEC; now handled properly.
+
+ * vax.md (casesi): Make pattern agree with machine instruction;
+ specifically, index is multiplied by two and the comparison is LEU,

+ (break_out_memory_refs): Refine which constants get broken out.
+ * expmed.c (store_bit_field, extract_bit_field): Don't use
+ gen_highpart for multi-word fields; instead, loop and use
+ operand_subword. We now support fields more than two words long.
+ (mask_rtx, lshift_value): Just pass high and low words to

+ (immed_double_const): For integer constants, perform any needed
+ masking and make either CONST_INT or CONST_DOUBLE.
+ (force_const_double_mem): Deleted; would need a mode arg added

+ of gen_lowpart and gen_highpart.
+
+ * function.c (find_replacement): New function.

+
+ * cplus-expr.c (decl_in_memory_p): New function.
+ * cplus-typeck.c (mark_addressable): Test `decl_in_memory_p' instead
+ of testing memory_operand, since the DECL_RTL of a decl may be a

+
+ * cplus-typeck.c (mark_addressable): When we decide that a static
+ const variable must go to memory, make sure that its rtl is
+ allocated from the correct obstack.
+
+ * cplus-decl.c (grokdeclarator): Replace undocumented BREAK_C_TAGS
+ #define control with comments explaining why or how it is correct
+ for GNU C++ to break C's notions of what a tag is.
+
+ * cplus-call.c (convert_harshness): Replace undocumented #if

+
+ * rtlanal.c (reg_referenced_p): New function.
+ * combine.c (try_combine): Correct test for added_sets_1 to account
+ for case where I1 and I2 both feed I3.
+ (distribute_notes): Don't interpret setting a reg as a use of the
+ reg; use new reg_referenced_p and simplify code.
+
+ * flow.c (propagate_block): Ensure that LOOP_DEPTH is correct at all
+ insns in a basic block, otherwise reg_n_refs will be set incorrectly.
+
+ * recog.c (validate_replace_rtx_1): Don't change mode of memory
+ reference that is mode-dependent.
+ Don't make a MEM with a larger mode than original.
+
+ * combine.c (try_combine): Disable code to check MODES_TIEABLE_P
+ added May 20th and 22nd; this should not be needed now that
+ LIMIT_RELOAD_CLASS has been added to reload.
+
+ * flow.c (mark_set_1): Allow for the fact that stack pushes don't have
+ REG_INC notes.
+ * local-alloc.c (optimize_reg_copy): Likewise.

+ A USE of a register must not be changed.
+ (validate_equiv_mem): Don't make an equivalence to volatile MEMs.
+
+ * reorg.c (mark_set_resources): #ifdef PUSH_ROUNDING, mark SP as always

+Fri May 31 16:11:57 1991 Ken Raeburn (raeburn at watch.com)
+
+ * cplus-lex.c (process_next_inline): Set line number and filename if
+ more inline data is to be processed.
+ (store_pending_inline): Treat FUNCTION_TYPE like METHOD_TYPE. Use
+ current_class_type instead of extracting it from method type; the
+ two should be the same, and the latter doesn't work for statics.
+
+ * cplus-decl.c (start_decl): When constructing templates, use
+ original name of function rather than "mangled" name. Look for
+ FUNCTION_DECL, not FUNCTION_TYPE, when deciding how to push the
+ new decl.
+ (start_method): Default inlining does not apply to template
+ expansions.
+
+ * cplus-pt.c (pending_template_expansions): Moved declaration to
+ start of file.
+ (tsubst): For FUNCTION_DECL, use original name of source, not
+ mangled name.
+ (instantiate_template): Local variables now non-static. Fill in
+ pending-inline field of new decl, rather than template-info, and
+ chain into either pending-inlines or pending-template-expansions.
+
+ * cplus-typeck.c (build_x_function_call): If a template is found,
+ treat it as an overloaded declaration.
+
+Fri May 31 14:20:45 1991 Richard Stallman (rms at mole.gnu.ai.mit.edu)

+ * tm-next.h (EXTRA_SECTION_FUNCTIONS):
+ Add new constructor and destructor sections.
+ (MAX_OFILE_ALIGNMENT): Define as 2^15 for Mach-O.
+ (ASM_OUTPUT_ALIGN): Use .align, not .even. Allow alignments > 2.
+ (CPP_PREDEFINES): Added -Dm68k since some code expects this.
+
+Fri May 31 05:41:51 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
+
+ * cplus-class.c (pushclass): New argument value for MODIFY accepted.
+ * cplus-decl2.c (build_push_scope): Call `pushclass' with MODIFY == 3.
+
+ * cplus-decl.c (finish_function): Set TREE_PUBLIC and TREE_EXTERNAL
+ bits on functions according to #pragma interface/implementation,
+ regardless of whether or not the function's inline. This fixes the

+ after the first cse pass.
+
+ * local-alloc.c (validate_equiv_mem_from_store, validate_equiv_mem):
+ New functions, to find cases where a REG is equivalent to a MEM.
+ (optimize_reg_copy): New function.
+ (update_equiv_regs): Call these new functions.
+ Look for a register used in only one basic block being stored into
+ memory.
+ Keep track of loop depth so we can find regs used only once, but
+ inside a loop.
+ * reload1.c (reload): Use single_set when looking for an insn
+ that initializes a register.
+ If making a REG equivalent to a MEM, the insn with SET_DEST being
+ the register isn't always the one making the equivalence, since the
+ equivalence might be occurring due to a store into MEM; in that
+ case set reg_equiv_init to the latter insn.
+
+Thu May 30 14:23:01 1991 Ken Raeburn (raeburn at watch.com)
+
+ * Pending expansions processed at end-of-file can be processed out
+ of order, so freeing the associated data from the obstacks is not
+ possible.
+ * cplus-tree.h (struct pending_inline): New field can_free
+ indicates whether to free the text after processing it.
+ * cplus-lex.c (do_pending_inline, process_next_inline): If

+ (cons_up_default_function): Clear flag.
+ (reinit_parse_for_method): Set it.
+ (store_pending_inline): Clear it when changing obstacks.

+ value after swapping obstacks, not before.
+
+Thu May 30 07:23:18 1991 Michael Tiemann (tiemann at cygnus.com)
+
+ * va-sparc.h: Has to be a char * to be compatible with Sun.
+ i.e., we have to pass a `va_list' to vsprintf. Also, fixed
+ bug in passing vararg structs.
+
+Thu May 30 00:32:18 1991 Richard Stallman (rms at mole.gnu.ai.mit.edu)
+
+ * configure: Delete Makefile.tem before writing it.
+
+ * stor-layout.c (layout_record):
+ Ignore PCC_BITFIELD_TYPE_MATTERS for incomplete type.

+ * function.c (assign_parms): Don't declare args_so_far register.
+
+Wed May 29 15:13:05 1991 Ken Raeburn (raeburn at watch.com)
+
+ * cplus-tree.def (TEMPLATE_PARM_IDX): Deleted.
+ (TEMPLATE_TYPE_PARM): New node type, looks like a type node.
+ (TEMPLATE_CONST_PARM): New node type, looks like a const node.
+
+ * cplus-tree.h (IDENTIFIER_TYPE_VALUE_PTR): Inlined under gcc.
+ (TYPE_IDENTIFIER_PTR): Ditto.
+ (DECL_NESTED_TYPENAME_PTR): Ditto.
+ (struct lang_type): New bitfield `use_template'.

+ (struct lang_decl): New field `template_info'.
+ (DECL_TEMPLATE_INFO): Accessor macro for above.
+ (TEMPLATE_EXPANSION_NAME_P): Deleted.
+ (push_overloaded_decl_top_level): Added declaration.
+ (TEMPLATE_TYPE_TPARMLIST, TEMPLATE_TYPE_IDX,
+ TEMPLATE_TYPE_SET_INFO, TEMPLATE_CONST_TPARMLIST,
+ TEMPLATE_CONST_IDX, TEMPLATE_CONST_SET_INFO): New macros for
+ accessing fields of TEMPLATE_..._PARM nodes.
+ (struct pending_inline): New fields for names and values to bind
+ to them while processing.
+ (struct template_info): Definition moved here from cplus-pt.c.
+ (instantiate_template): Added declaration.
+ (instantiate_class_template): Ditto.
+ (processing_template_{decl,defn}): New variable declarations.
+
+ * print-tree.c (print_node): Provide missing argument to
+ print_node for `bitpos' field. Display `virtual' flag, and (for
+ function and method types) `class' field; these are only used by
+ C++ that I'm aware of, but are defined in common code, so they
+ should be displayed here.
+
+ * cplus-parse.y (template_def): Separate set of derivations, for
+ class and function templates. Template_def is a type of extdef;
+ extern_lang_string before template_def is not permitted.
+ (fn_tmpl_end): New nonterminal, anything that signals the end of
+ the portion of a template that we should parse.
+ (yyprint): Define only if YYDEBUG. Handle TYPESPEC.
+ (datadef): Complain at class template override declaration if that
+ specialization has already been produced by expansion. Template
+ definitions no longer belong here.
+ (tmpl.2): Always call instantiate_class_template; let it decide
+ whether or not to go through with it.
+ (template_instantiation): Put decl in global scope only if not
+ already there.
+ (typespec, scoped_typename): Scoped typename inside template type
+ should be a scoped_typename, not a typespec. However, a
+ template_type should be allowed as a typespec.
+ (structsp): Don't undo template name overload here. Deleted
+ derivation from template_type.
+ (named_class_head_sans_basetype): Don't overload template name.
+ (LC): Do it here.
+ (notype_declarator): For scoped_id derivations, don't call
+ build_push_scope if the scoped_id is a SCOPE_REF.
+ (scoped_id): Moved old typespec-from-template_type rule here.
+ Call resolve_scope_to_name only if template parms aren't involved.
+
+ * cplus-pt.c (struct template_info): Definition deleted.
+ (templates, current_template_info): Variables deleted.
+ (processing_template_{decl,defn}): New variables.
+ (push_template_decls, pop_template_decls): Accept parmlist and
+ arglist as separate arguments, instead of deriving both from the
+ template. If class_level is non-zero, push and pop a level,
+ making it transparent to tags. Removed some pointless checks from
+ pop_template_decls that are only needed in push_template_decls,
+ and some assertions from both. Callers changed.
+ (uses_template_parms): Return non-zero iff argument refers to any
+ TEMPLATE_*_PARM nodes.
+ (tsubst): Walk tree, substituting for template parms, returning
+ new tree.
+ (type_unification): Rewritten a bit, to make it work. New
+ argument nsubsts is pointer to place to record number of
+ substitutions made when matching.
+ (unify): Renamed from unify1. Rewritten completely, to work.
+ Still may need extending for some tree node types.
+ (do_pending_expansions): At end-of-file, expand any templates not
+ yet expanded which were actually needed. Needs work to accomodate
+ latest specs.
+ (process_template_parm): Simplified slightly. Non-type parms
+ should be marked read-only; aggregate types are not allowed, since
+ equality checks don't work.
+ (end_template_parm_list): Moved to after process_template_parm.
+ Push a level, and push decls for TEMPLATE_*_PARMs. Set
+ processing_template_decl flag.
+ (end_template_decl): For non-class templates, build a
+ TEMPLATE_DECL and store the regular decl in its result field.
+ Context and other values get copied over too. Call poplevel to
+ get rid of the TEMPLATE_*_PARM decls, and call
+ dont_forget_overload to avoid losing the declaration later. Clear
+ processing_template_decl flag. Call get_pending_sizes, so later
+ function compilation doesn't try to evaluate sizes of templates.
+ (mangle_class_name_for_template): Convert type/non-type check from
+ switch to if test. Added support for ENUMERAL_TYPE, REAL_TYPE,
+ and POINTER_TYPE parms.
+ (instantiate_class_template): Renamed from old
+ instantiate_template. Don't expand if type size is set, or if
+ being-defined flag is set, or use-template flag is non-zero. If
+ other-template parms are used in the parm list, construct a simple
+ RECORD_TYPE node and return it. Catch case of template declared
+ but not defined before use. Renamed argument from class to
+ classname. Set processing_template_defn flag.
+ (instantiate_template): New routine; constructs new decl node
+ given TEMPLATE_DECL node and template arg vector.
+ (end_template_instantiation): Set use-template field to 2 ("did
+ use template"). Clear processing_template_defn flag.
+ (reinit_parse_for_template): Get template-info ptr from decl node.
+ Store template parm vector in it.
+ (pending_template_expansions): List of templates that may need
+ expanding later for function or class data definitions.
+
+ * cplus-method.c (build_overload_value): Ensure tree code is
+ PARM_DECL. Handle ENUMERAL_TYPE like INTEGER_TYPE. For DImode
+ values, compare against integer_zero_node instead of constructing
+ another one. Added support for POINTER_TYPEs. If not
+ REAL_IS_NOT_DOUBLE, support real values as well.
+ (build_overload_name): Accept TEMPLATE_*_PARM nodes, but generate
+ a string that should cause some assembler errors.
+
+ * cplus-ptree.c (print_lang_decl): Retrieve template-info from its
+ new place.
+ (print_lang_type): For TEMPLATE_TYPE_PARM, print its (short) info
+ and return. For RECORD_TYPE, print use-template and interface-*
+ fields.
+
+ * cplus-search.c (push_class_decls): Don't call
+ push_template_decls; the bindings of template parameter names
+ should be associated with the template body, not with the class.
+ Do overload the template name, however.
+ (pop_class_decls): Don't call pop_template_decls.
+
+ * cplus-call.c (build_method_call): Changed to recognize
+ constructor of template class.
+ (build_overload_call): Add in number of template substitutions as
+ extra cost of a candidate function. For template decls, try
+ unification and instantiation before evaluating cost of result.
+ This too is incorrect in terms of the spec, but it's a starting
+ point for later work.
+
+ * cplus-class.c (finish_struct): If structure is named, undo
+ overload of its name as a template.
+ (pushclass): If prev_class_type was a template class, pop it; the
+ decls are handled wrong and should be re-entered.
+
+ * cplus-decl.c (poplevel): Assert that the current level is not
+ global.
+ (push_to_top_level): Include global scope when looking for old
+ values, because class bindings aren't listed in any other one
+ place.
+ (push_overloaded_decl_top_level): New function; like
+ push_overloaded_decl, but places decl in global binding level.
+ (dont_forget_overload): New function; removes decl from list of
+ overloads to be forgotten when scope is exited.
+ (start_decl): If template parms are used, construct a
+ TEMPLATE_DECL node referencing the current decl. For function
+ templates, call push_overloaded_decl; for class template members,
+ chain them into the class template definition.
+ (grokdeclarator): Don't try determining size of a
+ TEMPLATE_CONST_PARM node. For template class-data decls,
+ construct a phony VAR_DECL node and return it.
+
+ * cplus-decl2.c (grokfield): For static class data, use
+ build_overload_name result, instead of copying class name, since
+ the latter could be a human-readable template class name. (If
+ NEW_OVERLOAD_SCHEME is not defined, do this only if the class has
+ a template-derived name.)
+
+ * cplus-lex.c (pending_template_obstack): New variable; obstack
+ for pending-template stuff to be saved to end-of-file.
+ (init_lex): Initialize it.
+ (default_def): New variable; used for default definition of copy
+ constructors and destructors.
+ (do_pending_inlines): Figure out whether text is in an obstack,
+ and which one, for calling feed_input. Push template decls if
+ needed, as specified in pending_inline data. Pass current
+ pending_inlines pointer back in PRE_PARSED_FUNCTION_DECL instead
+ of next.
+ (process_next_inline): Ditto. Pop pending inline data if needed.
+ (store_pending_inline): New function. Decides which obstack to
+ store a pending definition on, and which list to chain it into.
+ (reinit_parse_for_method): Call it.
+ (reinit_parse_for_block): If character passed in is '=', look for
+ a semicolon to end the block; don't require a {} block. Don't pad
+ to 8 bytes on USG, since we aren't feeding input via stdio any
+ more. Also, use newlines instead of # directives for advancing
+ line number only a few lines.
+ (cons_up_default_function): Punt padding for USG stdio, since we
+ aren't using it any more. Use default_def for definition. Call
+ store_pending_inline to save it away.
+ (identifier_type): For TEMPLATE_DECL, DECL_RESULT field non-null
+ indicates a non-type template, so don't return PTYPENAME.
+ (yylex): If end-of-file and input isn't redirected, call
+ do_pending_expansions and maybe start yylex over. Don't check
+ TEMPLATE_EXPANSION_NAME_P; a proper name transformation system
+ will eliminate conflicts. Try for SCOPED_TYPENAME with PTYPENAME
+ too.

+ (function_prologue): INIT_CUMULATIVE_ARGS now takes 3 args.
+ (function_epilogue): If current_function_epilogue_delay_list is
+ non-null, use that to fill the final delay slot. Also, make sure

+
+ * mips-tfile.c (whole file): New file to put the MIPS specific debug
+ information into the object file, after the assembler has been run.

+ setting up the debug information for local variables. This is
+ enabled by the make-mips Makefile modifier.
+
+ * mips-tdump.c (whole file): New file to dump the contents of the
+ MIPS ECOFF symbol table in a symbolic format. This is not currently
+ built by default, but make-mips contains rules to build it.

+
+ * tm-sparc.h (GO_IF_LEGITIMATE_ADDRESS): Don't accept a SYMBOL_REF

+ * out-sparc.c (print_operand): New function, implementing actions of

+ associated with CNAME.
+
+ * cplus-class.c (build_vbase_path): Fix 11 May change by only
+ changing TREE_TYPE (EXPR) if NULL_EXPR. We might build different
+ vbase paths for the same expr in multiple inheritance
+ initialization.
+
+ * Makefile.in: Change sed script so it matches '^# ' instead of just

+ gave method qualifiers for function decl.
+ (start_function): Switch to temporary obstack before computing
+ destructor and constructor labels, and before building the
+ function's RESULT_DECL.
+
+ * cplus-decl.c (store_parm_decls): Make a cleanup that controls the
+ action of the garbage collector. This ensures that the call to

+
+ * expr.c (force_operand): When calling recursively, use
+ a temporary to force evaluation of calls. The C language

+ * recog.c (const_double_operand): New function for recognizing
+ CONST_DOUBLE rtx's.
+

+ set only the condition code and that set both the condition code
+ and a normal result.
+ Delete "cc" attribute and add "type" attribute.
+ Define delays for cc-setting insns and for loads.
+ Replace `d' constraint with `r'.
+ Delete patterns for HImode and QImode arithmetic operations.

+ (refers_to_mem_p): Handle the case when `base' is a LO_SUM.
+ * integrate.c (FIXED_BASE_PLUS_P): Define this to recognize offsets
+ from the various virtual registers.
+ (expand_inline_function): Expand exprs using EXPAND_SUM so as to get
+ stack frame addresses instead of pseudos. This yields much better
+ cse (at little cost) for GNU C++. Also, test FIXED_BASE_PLUS_P as
+ an alternative to CONSTANT_P to record a known register value.
+ * jump.c (find_cross_jump): If we are processing a cross jump and
+ the insns fail to match, try looking for a REG_EQUAL note that makes

+
+ * cplus-decl.c (maybe_build_cleanup): Add LOOKUP_NONVIRTUAL to flags
+ argument in call to `build_delete' if DECL does not use virtual
+ baseclasses. If it does, we go through a function call to save
+ space, unless FLAG_EXPENSIVEO_OPTIMIZATIONS is nonzero. ??Better
+ approach is to know, in expand_cleanups, to clear `flag_no_inline'
+ during the cleanup's expansion.
+

+ where we know we are calling a destructor for a non-null object.
+

+ * function.c: Add declaration for `current_function_uses_const_pool'.
+ * expr.h: Add extern declaration for that variable.

+ * function.c ({push,pop}_function_context): save and restore the
+ value of `current_function_uses_const_pool'.
+ * rtl.h (FUNCTION_FLAGS_USES_CONST_POOL): Defined to be 0200.
+ * integrate.c (initialize_for_inline):
+ FUNCTION_FLAGS_USES_CONST_POOL now contributes to the value of
+ `function_flags'.
+ (output_inline_function): Restore `current_function_uses_const_pool'
+ from `function_flags'.
+ (save_for_inline_copying): Only call `save_constants' if
+ `current_function_uses_const_pool' is nonzero.
+ (save_for_inline_nocopy): Ditto.
+ (save_constants): Tweaked to perform its treewalk faster. Notably,
+ it no longer accepts ptrs to NULL rtl. All callers changed.
+ * varasm.c (force_const_mem): Set `current_function_uses_const_pool'
+ if we create a constant pool reference.
+
+ * cplus-parse.y, c-parse.y: Add new function `set_yydebug'. If
+ YYDEBUG is defined, sets `yydebug' to VALUE. Otherwise, prints
+ warning that operation is invalid.
+ * toplev.c (main): Call `set_yydebug' instead of setting `yydebug'
+ directly. This allows user to turn YYDEBUG off for faster parsing.
+
+ * cse.c (simplify_binary_operation): Eliminate abort when passed
+ DImode operands.

+ * reload1.c (basic_block_needs): Now an array, per register class.
+ (reload): Compute separate basic_block_needs for each class.
+ (spill_hard_reg): If pseudo is only in one block, see if that block

+ (reload_reg_class_lower): Use them.
+ (allocate_reload_reg): New function.
+ (choose_reload_regs): Track size and class of any groups. We
+ can inherit reloads if we are the size of the largest group or
+ if our class is disjoint from those needed for groups.

+
+ * jump.c (jump_optimize): Update the three simplications that start
+ with the "if (...) x = 1; else {...} if (x) ..." case, so that when
+ HAVE_cc0 is not defined, they do not accept TST insns (which could

+ set was to the same register, not just the same quantity;
+ if previous REG_WAS_0 note, update back pointer.
+ If setting a register to a constant, update QTY_CONST and

+
+ * expmed.c (synth_mult): Make it handle t == 0. Improve comments.
+ Use (max_cost <= add_cost) instead of (max_cost < add_cost) to

+
+ * make-cc1.com: Update for GCC 2.0; build insn-attr.h, insn-attrtab.c.

+Sun May 5 14:30:14 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
+
+ * cplus-class.c (prev_class_type): Declare this to be static.
+ (build_vbase_path): Test NONNULL to decide whether a COND_EXPR is
+ actually needed.
+ (finish_struct): Another sort of hard virtual function to deal with
+ is one which comes from the non-leftmost baseclass, and who's index
+ is different between that class and the main derived class. Use new
+ variable DOING_HARD_VIRTUALS to control when we punt and when we
+ plow through.
+ (modify_vtable_entry): If we find at this point that we have a hard
+ virtual function, just put it on the list PENDING_HARD_VIRTUALS if
+ DOING_HARD_VIRTUALS is nonzero.
+ (fixed_type_p): Handle SAVE_EXPR, RTL_EXPR, PLUS_EXPR, MINUS_EXPR,
+ NOP_EXPR and CONVERT_EXPR.
+ (pushclass): Fixed comment. Also change test for whether this is

+ we'll have to rewrite this to actually use it.
+
+ * cplus-gc.c (type_needs_gc_entry): Don't need a GC entry for
+ ERROR_MARK_NODE.
+
+ * cplus-init.c (build_new): Set TREE_CALLS_NEW on RTL_EXPR. This

+ with GNU C.
+ (tree_node_kinds): Renamed to `tree_node_counts'.
+
+ * cplus-parse.y (various places): Take advantage of default rule

+ type.
+ (finish_decl): Don't crash if TYPE is error_mark_node.
+
+ * fold-const.c (split_tree): When splitting the tree, don't call
+ convert if the TYPE_MODEs are the smae. This screws up C++ where
+ conversion of one pointer type to another can cause the pointer's
+ value to change.
+
+ * tree.c (get_identifier): Speed up `get_identifier' by about a
+ factor of 2. This becomes noticable with the long names used for
+ C++ overloading.
+ (tree_cons): Make this most frequent user of `make_node' perform its
+ actions inline.
+
+ * calls.c (expand_call): Eliminate many (most) calls to strcmp by

+
+ * cse.c (simplify_binary_operation): Remove obsolete code to convert
+ negative shift counts to the opposite shift.

+ is already in the desired register.
+
+ * combine.c (find_split_point): Add two more ways to split an insn.

+ putting constants second, just like subst would do.
+
+ * combine.c (significant_bits): Correct computation of significant bits
+ for division operations.
+
+ * combine.c (apply_distributive_law): Reject complex SUBREGs.
+ SUBREG distributes over logical and addition operations.
+
+ * combine.c (subst; case AND, IOR, XOR): Add some boolean
+ arithmetic simplifications.
+
+ * expr.c (do_jump): ADDRESS_EXPR is not always zero, unfortunately.
+
+ * expr.c (do_store_flag): In case where we are testing a single bit,
+ don't convert to output mode until after we do the shift.
+
+ * optabs.c (expand_binop, expand_unop, expand_fix): Compare
+ enum insn_code objects against CODE_FOR_nothing instead of 0.
+
+ * romp.md (bit_insv): Use CC0 in standard way; i.e., in NE.

+ with ZERO_EXTRACT as destination.
+ (ibitx): Put ASHIFT as first operand in XOR.
+ (bitfield compare): Remove comparison of 1 bit field with 1; combine
+ converts this to comparison with zero.
+ (and-compare-branch): Fold PLUS or MINUS into constant, like combine
+ will do.
+ Remove patterns for reversed cases.
+ * out-ns32k.c (const_int): Deleted.

+ * m68k.md (cmpsf, cmpdf, tstsf, tstdf for FPA): Use MATCH_SCRATCH.
+ * sparc.md (memory store patterns): Likewise.
+
+ * function.c (assign_parms): Function is varargs function if the
+ last parameter is `__builtin_va_alist_' instead of checking the first
+ parameter. Normally, this is the same, but some functions in MACH
+ have named parameters before va_alist.
+
+ * combine.c (simplify_comparison): Remove abort on paradoxical SUBREGs
+ now that we know they can occur.
+
+ * reload.c (decompose): Handle SCRATCH; it can't conflict with
+ anything.

+
+ * cplus-typeck.c (common_base_type): Make this function recursive.
+ (build_component_ref): Test whether or not a FIELD_DECL, not whether
+ or not a VAR_DECL||CONST_DECL||TYPE_DECL.
+
+ * cplus-parse.y: Fixed grammar so that template type decls could be
+ used. Previously, support existed for template decls following
+ types, but not as types.
+ * cplus-pt.c ({push,pop}_template_decls): New functions.
+ (instantiate_template): Call `push_template_decls'.
+ (end_template_instantiation): Let `poplevel' restore old bindings.
+ No need to clear out extra stuff.
+ (pushclass, popclass): Call `{push,pop}_template_decls' if the class
+ we are pushing or popping has template arguments. These arguments
+ go at class level.
+
+ * cplus-method.c (build_opfncall): Test TRY_SECOND before testing
+ possibly uninitialized XARG2.
+
+ * cplus-lex.c (init_lex): Initialize NODE_TABLE, OPNAME_TAB and
+ ASSIGNOP_TAB to hold zero. Since these come from malloc'd memory,
+ we cannot trust them to be initialized on startup.
+
+ * cplus-init.c (expand_aggr_init_1): When initializing through a
+ TARGET_EXPR for objects of the same type (e.g., X a = X (10);)
+ use EXP's DECL_RTL as the DECL_RTL of the TARGET_EXPR.
+
+ * cplus-decl2.c (finish_file): Handle new flag `-fgnu-binutils'.
+ When zero, don't use GNU extensions to a.out format. ???Should be
+ merged into varasm.c.
+
+ * cplus-class.c: Added support for `dossiers'. This support is
+ implemented by extending the virtual function table and by giving
+ all C++ objects a virtual function table to hold it's dossier.
+ * cplus-decl.c (record_builtin_type): New function to construct
+ dossier information for built-in types.
+ (output_builtin_tdesc_entries): To keep repeated information under
+ control, we only output this information for the file that contains

+ (init_decl_processing): Many dossier-related changes.
+ (init_lex): Recognize new reserved words `headof' and `classof' if
+ -fgc.
+ * cplus-parse.y: Grammar now recognizes `headof' and `classof'
+ expressions.
+ * cplus-method.c: Added dossier constructors here.
+ * cplus-tree.h (CLASSTYPE_DOSSIER): New macro: `dossier' is a new
+ field in lang_type.
+ * cplus-typeck.c (convert_for_assignment): Handle
+ `class_star_type_node'.
+
+ * cplus-class.c: New variable current_class_depth. Used to tell
+ what class nesting level the compiler is at.
+ * cplus-decl.c (grokdeclarator): Now supports references to decls
+ that come from nested types. For example, int foo::bar (foo_tag);
+ where `foo_tag' is a tag that comes from foo. Previously this was
+ supported only as int foo::bar (foo::foo_tag);
+ * cplus-decl2.c (build_push_scope): build a SCOPE_REF node while
+ pushing into the context for the scope. When `grokdeclarator' sees
+ one of these nodes (distinuished by its TREE_COMPLEXITY being set to
+ the current_class_depth), it processes the decl and pops the scope.
+
+ * cplus-class.c (build_vbase_path): Trust objects that are
+ `fixed_type_p'. Also, don't assume an object is non-null unless
+ flag says this is explicitly so. InterViews creates and may
+ manipulate (via delete) lots of null objects.
+ (build_vfn_reference): Use IS_AGGR_TYPE test on type, not in

+
+Mon Apr 29 12:58:19 1991 Jim Wilson (wilson at cygnus.com)
+
+ * sched.c: (schedule_block): Rewrite code that computes which

+
+ * m88k.md (symbolic store patterns): These patterns are all
+ unnecessary and are deleted.

+
+ * cplus-class.c (prepare_fresh_vtable): Thoroughly update virtual
+ function tables that come from baseclasses to contain the latest
+ overrides from derived classes. This was done (in a different way)
+ for virtual baseclasses, but left undone for non-virtual
+ baseclasses.

+ to walk through the classes base classes. This gives us more

+ inline, since this somehow reduces page sharing. Really???
+
+ * cplus-except.c (init_exception_processing): Use `pushdecl' to
+ install global info that this function sets up. That way later
+ decls can override this info (such as with an inline function).

+
+ * sched.c (init_alias_analysis): Handle REG_EQUIV notes just like
+ REG_EQUAL notes.
+
+ * sched.c (sched_analyze_2): Don't recurse on constant rtx's.
+ This is necessary so that the cc0_rtx in CONST_DOUBLEs won't be seen.
+ (sched_analyze): Call sched_analyze_insn for JUMP_INSNS also, so
+ that cc0 users will get an automatic dependence on their previous
+ insn.
+ (launch_links): Ifdef out special treatment of insns which set the
+ condition codes. This is obsolete, and was SPARC specific anyways.
+ (new_sometimes_live): Clarify code that aborts if regno is greater
+ than max_regno.
+ (schedule_block): If the last insn sets cc0, then it must always
+ be left in place.
+ (new_insn_dead_notes): New function. Determines whether a SET or
+ CLOBBER in an insn created by splitting needs a REG_DEAD or
+ REG_UNUSED note added.
+ (update_links): Ignore REG_EQUIV and REG_EQUAL notes on insns that
+ have more than one set. Generalize flow analysis of the sets in
+ the new insns so that it can handle new insns which have multiple
+ sets or new clobbers.
+
+Mon Apr 22 08:15:50 1991 Michael Meissner (meissner at osf.org)
+
+ * gcc.c (input_suffix): New global var; holds current file's suffix.

+Sat Apr 20 10:45:43 1991 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * loop.c (check_dbra_loop): Use GET_RTX_CLASS when appropriate.
+ Check for setting biv with single_set rather than only allowing a SET.
+ If a loop has a `break', we can't reverse it.
+
+ * cse.c (cse_insn): Fold inside operands of a CALL (mostly to find the
+ best address form to use).
+
+ * cse.c (simplify_unary_operation): Convert (neg (neg ..)) to NEG.
+ Similarly for NOT.

+
+ * tm-a29k.h (OPTIMIZATION_OPTIONS): Allow insn scheduling to be
+ enabled, now that it works for the 29k.
+
+ * tm-rs6000.h (LINK_SPEC): Add "-bhalt:4" to LINK_SPEC (don't ask!).
+
+Fri Apr 19 13:18:52 1991 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * explow.c (memory_address): Test `cse_not_expected' instead of

+
+ * genflags.c (gen_insn): If extra condition is more than one line,
+ use \'s to make proper multi-line macro definition.
+
+Thu Apr 18 13:40:01 1991 Jim Wilson (wilson at cygnus.com)
+
+ * loop.c (check_dbra_loop): Reenable no_use_except_for_counting code
+ which was mistakenly ifdefed out as buggy. The actual bug was in
+ strength_reduce, and has already been fixed.

+
+ * out-romp.c, out-rs6000.c (next_insn_tests_no_unsigned): If a
+ REG_UNUSED note for (cc0) is present on INSN, return 1.
+
+ * jump.c (delete_jump): If the previous insn sets cc0 but we can't
+ delete it for some reason, add a REG_UNUSED note for cc0 in that insn.
+
+ * out-a29k.c: Rename input_operand to in_operand and output_operand
+ to out_operand to avoid conflict with output_operand in final.c.
+ * a29k.md: Likewise.
+ (call patterns): Don't put SYMBOL_REF in MEM for recursive call;
+ it might not be recursive if inlined; let cse do it later.
+ * tm-a29k.h (RTX_COST, ADDRESS_COST): All addresses have the same
+ cost, but MEM is expensive.
+

+
+ * unroll.c (final_giv_value): Use expand_binop instead of
+ gen_sub2_insn when emitting subtract insns, since expand_binop
+ will work for any operands.
+
+ * sched.c (schedule_insns): Don't split no-op moves; doing so
+ breaks the code that handles REG_NO_CONFLICT blocks.
+ (update_links): Delete the code that prints a warning for
+ REG_EQUAL notes where the original dest can't be found. This no
+ longer occurs because of the above change.
+
+ * sched.c: Generalize memory aliasing code so that it will work on
+ non-RISC machines. Instead of saving just the insn on the pending
+ lists, now saves both the insn and the mem rtx. Old variables
+ pending_read and pending_write replaced with pending_read_insns,
+ pending_read_mems, pending_write_insns, and pending_write_mems.
+ (read_dependence, true_dependence, anti_dependence,
+ output_dependence): Now passed a MEM rtx instead of a PATtern.
+ (add_insn_mem_dependence): New function. Adds an insn and a mem
+ to a pending list pair.
+ (sched_analyze_1, sched_analyze_2, sched_analyze): Modified to use
+ new pending list scheme.
+ (schedule_block): Likewise.
+ (schedule_insns): Likewise.
+
+Tue Apr 16 12:31:07 1991 Jeffrey A. Law (law at mole.gnu.ai.mit.edu)
+
+ * Makefile.in (install-man): Look for protoize.1 and unprotoize.1
+ in the current directory, not $(srcdir)
+ (install-headers): Use basename to strip off $(srcdir) from
+ include files when installing and changing mode.
+

+
+ * rs6000.md (extendqixi2): Add CLOBBER to the first SET as well as
+ the second.
+ (load_multiple): Fix typo in operand number and add newline.
+
+ * reload.c (find_reloads_address_1): Pass actual location of a
+ MEM used in an address; also handle the case when the MEM was
+ copied. Ensure we reload the copy, not the original address.
+
+ * reload1.c (eliminate_regs, case {INSN,EXPR}_LIST): Correctly handle
+ the cases when one or more operations is (nil).
+
+ * local-alloc.c (block_alloc): Check for REG_EQUAL on list insn
+ of REG_NO_CLOBBER sequence, not first.
+ (no_conflict_p): Set LAST and use INSN instead of P for loop start.
+
+Mon Apr 15 12:55:12 1991 Jim Wilson (wilson at cygnus.com)
+
+ * loop.c (strength_reduce): Don't emit an insn after loop_end to
+ set the final value of a reversed biv. There is already an insn
+ there setting the biv's proper final value.
+
+Sun Apr 14 18:32:05 1991 Michael Tiemann (tiemann at cygnus.com)
+
+ * gnulib1.c (various functions): Added declaration of INTIFY to

+
+Sun Apr 14 18:31:59 1991 Richard Stallman (rms at mole.gnu.ai.mit.edu)
+
+ * c-decl.c (store_parm_decls): Traditional float parm becomes double.
+
+Sat Apr 13 17:35:07 1991 Richard Stallman (rms at mole.gnu.ai.mit.edu)
+
+ * m68k.md (storing 32-bit field with movl): Allow any immediate arg 3.
+
+ * expmed.c (store_bit_field): For fields bigger than a word:
+ Avoid special use of SImode, and don't crash if VALUE is CONST_INT.
+
+Fri Apr 12 02:04:46 1991 Richard Stallman (rms at mole.gnu.ai.mit.edu)
+
+ * reload.c (find_reloads): Like prev change here, for optional reloads.
+
+ * tm-sparc.h (FUNCTION_BLOCK_PROFILER): Must set %o0 to the address
+ LPBX0 by adding in the low part of the address before calling
+ ___bb_init_func.
+
+ * tm-next.h (ASM_OUTPUT_CONSTRUCTOR, ASM_OUTPUT_DESTRUCTOR):
+ New macros. Place reference to constructor or destructor into
+ constructor or destructor section.
+
+ * tm-next.h (EXTRA_SECTIONS, EXTRA_SECTION_FUNCTIONS): Add
+ new constructor and destructor sections.
+
+ * jump.c (squeeze_block_notes,squeeze_notes): Chage the name of
+ squeeze_block_notes to squeeze_notes. Also handle LOOP_BEG, LOOP_CONT
+ and LOOP_END notes, since these must remain in their original order.
+
+ * cccp.c (skip_to_end_of_comment): Handle warn_comment.
+
+ * m68k.md (dbra patterns): Use `=' in constraint of op 0.
+
+ * gcc.c (process_command): Handle -save-temps.
+ (do_spec_1): Handle %g like %b if -save-temps.
+ (verbose_flag): Renamed from `vflag'.

+
+Fri Apr 12 00:57:48 1991 Jim Wilson (wilson at cygnus.com)
+
+ * sched.c: Update all comments to reflect source changes.
+ Make old_live_regs a static global, instead of local to schedule_block.
+ Schedule_block is now void, since its return value was always 1.
+ Rename last_function_call_not_const to last_pending_memory flush.
+ This can not be a CALL_INSN or a INSN that writes memory.
+ New variable pending_lists_length so that the lists can be flushed
+ when they get too long.
+ Use GET_RTX_CLASS instead of multiple GET_CODE calls whenever it
+ makes sense.
+ (read_dependence): New Function. Returns one if two reads are
+ dependent. This can happen if both are volatile reads.
+ (true_dependence, anti_dependence, output_dependence): Two volatile
+ memory access are always dependent.
+ (order_calls): Function deleted. It was very short, it was only called
+ once, and it no longer did what its name implied. Its one call was
+ replaced with the body of the function.
+ (sched_analyze_1): Correctly handle stripping of SUBREGs, etc from
+ the set dest.
+ If the pending lists are longer than 32 when processing a memory
+ write, then make this write depend on all previous and all future
+ memory accesses so we can flush the pending list. This is necessary
+ because the algorithms used are O(N*N).
+ (sched_analyze_2): For memory reads, check whether it is read
+ dependent on any previous memory read (this can happen if both reads
+ are volatile).
+ (sched_analyze_insn): Replace call to order_calls with the body of
+ that function.
+ (sched_analyze): Don't clear last_memory_pending_flush for a non-const
+ call, since any future call must still depend on all previous memory
+ accesses.
+ (sched_note_set): Correct handling of SUBREGs, etc. For partial sets
+ of a register, must treat this exactly the same way as flow.c, i.e.
+ a partial set of a register does not kill the register. Delete
+ ifdefed out code which is obsolete.
+ (attach_deaths): New argument SET_P, which indicates whether this is
+ a set (if true) or a use (if false) of the rtx X. Correct handling
+ of REG_DEAD notes, to account for the new REG_UNUSED note.
+ (attach_deaths_insn): Pass new additional parameter to attach_deaths.
+ Always call attach_deaths for sets within a parallel. Call
+ attach_deaths for clobbers.
+ (new_sometimes_live): Ifdef out code which should never be executed,
+ and replaced with call to abort.
+ (schedule_block): Now void.
+ When processing block to find dead_regs, don't unlink REG_UNUSED notes,
+ but must mark the indicated register as dead.
+ (update_links): Completely rewritten to make more general. Now handles
+ all REG_NOTEs except REG_INC and REG_LABEL. No longer makes simple
+ assumptions about the form of instructions. New argument orig_insn,
+ which is the original unsplit insn.
+ (schedule_insns): Delete unused volatilep code. Pass new parameter
+ to update_links.
+
+Thu Apr 11 15:34:44 1991 Tom Wood (wood at dg-rtp.dg.com)
+
+ * out-m88k.c (pic_addressing_base_rtx): Use pic_offset_table_rtx
+ instead. Otherwise, PIC fails miserably for inline functions.
+ (legitimize_address): Support -mbig-pic.
+ (print_operand): Add `g' for printing #got_rel (for -mbig-pic).
+ * tm-m88k.h (CONDITIONAL_REGISTER_USAGE): PIC_OFFSET_TABLE_REGNUM
+ is used and is fixed for PIC.
+ (GO_IF_LEGITIMATE_ADDRESS): Distinguish the -mbig-pic case.
+ * m88k.md (SImode hi16/lo16): Use %g for -mbig-pic.
+
+Wed Apr 10 21:53:32 1991 Jim Wilson (wilson at cygnus.com)
+
+ * unroll.c: Change global variable declarations to static.
+ Four new global variables loop_iteration_var, loop_initial_value,
+ loop_increment, and loop_final_value, used for communication between
+ loop_iterations and precondition_loop_p.
+ (unroll_loop): Before deleteing the insns in the original loop body,
+ emit a label after the last insn to be deleted, to ensure that no
+ delete_insn call will delete past that point.
+ (precondition_loop_p): Use global loop_* variables setup by
+ loop_iterations, instead of trying to calculate their values again.
+ (copy_loop_body): Don't emit copies of the start_label.
+ (approx_final_value): COMPARISON argument now passed as the pair
+ COMPARISON_CODE and COMPARISON_VALUE.
+ (find_splittable_regs): When completely unrolling a loop, and the
+ initial value of a biv is a hard register or itself, then must
+ create a new register to hold its initial value for splitting.
+ (loop_iterations): Set the new global variables loop_*.
+ If the comparison value is an invariant register, then search the insns
+ before the loop to try to find a constant value for the register.
+
+Wed Apr 10 16:02:16 1991 Tom Wood (wood at dg-rtp.dg.com)
+
+ * out-m88k.c (pic_addressing_base_rtx): A pseudo register coined
+ for each function as needed in legitimize_address.
+ (emit_move_sequence): Use legitimize_address instead of generating
+ HIGH/LO_SUM.
+ (legitimize_address): Rework, based on the sparc version, to
+ implement PIC.
+ (output_call): Use the #plt form when doing PIC.
+ (m88k_layout_frame): The addressing base register is no longer
+ fixed and r1 need not be saved for PIC.
+ (output_prologue): Output instructions to setup the addressing
+ base register if one is needed.
+ (print_operand_address): Support the PIC case.
+ * m88k.md (most patterns using hi16/lo16): Disable these for PIC.
+ * tm-m88k.h (CONDITIONAL_REGISTER_USAGE): No longer needed.
+ (ADDRESSING_BASE_REGNUM): Derived from pic_addressing_base_rtx.
+ (GO_IF_LEGITIMATE_ADDRESS): Accept the PIC case.
+ (LEGITIMIZE_ADDRESS): Use legitimize_address instead of HIGH/LO_SUM.
+
+ * make-m88k, make-m88kdgux: Use SysV INSTALL = cp and for DG/UX,
+ use the bison -l option to allow debugging in c-parse.tab.c.
+
+ * From kenner@vlsi1.ultra.nyu.edu.
+ * out-m88k.c: Include insn-config.h before conditions.h, which
+ requires it.

+ * (68020): Test for __NeXT__ too.
+ * (68020 __umulsidi3, umul_ppmm, udiv_qrnnd):
+ Use constraints "dmi", not "g" (avoid address registers).
+ * (88000 add_ssaaa, sub_ddmmss): Use r modifier for output

+
+ * expmed.c (expand_divmod): Convert OP1 to COMPUTE_MODE when we
+ convert OP0.
+
+ * combine.c (subst): Use gen_binary.
+ (simplify_comparison): If we have a ZERO_EXTRACT from a constant
+ with only one bit set, convert into comparison of position with
+ location of bit in constant; this simplifies ((1 << x) & 1) == 0.
+
+ * combine.c (gen_lowpart_for_combine): Copy code for CONST_DOUBLE
+ from gen_lowpart instead of calling it; it will abort for certain
+ floating-point cases, while we will just surround the object with
+ a SUBREG.

+Thu Apr 4 22:31:36 1991 Jim Wilson (wilson at cygnus.com)
+
+ * unroll.c (new file): Implements loop unrolling. Completely
+ unrolls small constant bounded loops. Unrolls other constant
+ bounded loops by an amount modulo the number of iterations so that
+ only one exit test is needed. Preconditions loops whose iteration
+ count can be calculated at run time, so that only one exit test
+ is needed. Can also unroll any other loop by having multiple
+ copies of the exit tests. Tries to simplify addresses while
+ unrolling.
+
+ * tree.def: BLOCK trees have 4 fields, not 5.
+
+ * toplev.c: Add new flag -dt to dump RTL after the second cse pass.
+ Define two new flags, flag_unroll_loops and flag_unroll_all_loops,

+ exec time for the shorten-branch pass in the proper place, i.e.
+ after delayed branch reorganization.
+
+ * stmt.c (find_loop_tree_blocks): New function. Creates a mapping
+ between BLOCK trees and loops. This info is needed when doing both
+ loop unrolling and outputting debugger info.
+ (unroll_block_trees): New function. Makes COPIES copies of the block
+ trees corresponding the loop indicated by LOOP_NUMBER, so that the
+ BLOCK notes inside the loop will still match the BLOCK trees for
+ the loop.
+
+ * rtl.h: Document the new named pattern
+ "decrement_and_branch_until_zero". Add macros to access new
+ field of inline_header rtx, which holds a pointer to the function's

+ * rtl.def: New entry for inline_header to hold a pointer to the
+ function's original DECL_INITIAL tree.
+
+ * loop.h (new file): Move many declarations from loop.c to the new

+ and change some from static to extern, so that they can be shared
+ with unroll.c. Add misc comments to better explain the code.

+ loop_number_loop_starts and loop_number_loop_ends so that they won't
+ be confused with local loop_start and loop_end variables.
+ New variables loop_number_exit_labels, loop_number_first_block,

+ Move NOT to first operand so we'll try to split the other operand
+ first.

+ the compare there.
+
+ * cse.c (simplify_binary_operation): If eliminating reference to

+
+ * jump.c (jump_optimize): Remove needless incrementing of LABEL_NUSES

+ `insn_name_ptr' as a pointer to `insn_name' for use by print_rtx.
+ * final.c (output_asm_insn): Use the pattern name chosen by
+ genoutput and output the INSN_UID as well.
+ * rtl.c (insn_name_ptr): Provide an alternate definition to avoid
+ link errors when rtl.o is not linked with insn-output.o.
+ (print_rtx): When printing the INSN_CODE field of an insn, print

+
+Mon Mar 25 09:39:43 1991 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * regs.h (reg_first_use): Deleted.
+ * rtl.h (REG_UNSET): Deleted.
+ (REG_UNUSED): New note.
+ * combine.c (combine_instructions): Delete loop fixing up
+ reg_first_use.
+ (can_combine_p): Ignore a branch of a PARALLEL if its output is
+ never used.
+ (move_deaths): Don't update reg_first_use.
+ (distribute_notes): Don't handle REG_UNSET; add code for REG_UNUSED.
+ * flow.c (reg_first_use): Deleted.
+ (life_analysis): Restore code that marks vars live at start of function
+ as globals. These are registers that were never set.
+ (allocate_for_life_analysis): Don't allocate reg_first_use.
+ (propagate_block): Search for cc0-setting insn with prev_nonnote_insn.
+ (mark_set_1): Don't set reg_first_use.
+ If register is never used, make REG_UNUSED note, not REG_DEAD.
+ (mark_used_regs): Don't set reg_first_use.
+ * global-alloc.c (global-conflicts): Dead outputs are now denoted by
+ REG_UNUSED notes, not REG_DEAD.
+ * reload.c (find_dummy_reload): Delete test of REG_UNSET; add test
+ of REG_UNUSED.
+ (find_equiv_reg): Don't re-use an output marked as REG_UNUSED;
+ we want these notes to be accurate; this would rarely win anyway.
+ * reload1.c (emit_reload_insns): Test REG_UNUSED to see if an
+ output won't be used any more.
+ * reorg.c (mark_target_live_regs): Use REG_UNUSED notes to kill
+ registers dead after an insn.
+ * rtl.c (reg_note_name): Delete REG_UNSET, add REG_UNUSED.
+ * rtlanal.c (single_set): Ignore a SET whose output has a REG_UNUSED
+ note.
+ * sched.c (update_first_use): Deleted.
+ (update_links): No need to call update_first_use.
+
+ * local-alloc.c: Major changes to use REG_UNUSED notes, make
+ handling of only-set registers more consistent, and allow
+ two consecutive CLOBBERs to share a register. Also, avoid loops
+ over all register each basic block; eliminating these make local-alloc
+ three times faster!
+ Quantity numbers now start at zero.
+ (qty_first_reg, reg_next_in_qty): New variables.
+ (qty_clobber): No longer needed.
+ (reg_qty): -1 if register cannot be allocated by local-alloc.
+ Now undefined for hard registers.
+ (reg_offset): Now char *.
+ (call_seen): Deleted, never used.
+ (regs_live_at): Now two entries per insn.
+ (alloc_qty): Initialize chain of register in quantity.
+ (local_alloc): Remove all per-block loops over registers.
+ Only allocate qty_... vars for max_reg - FIRST_PSEUDO_REGISTER.
+ Initialize reg_qty once per function.
+ Don't initialize qty_... vars that are always set before use.
+ (block_alloc): Delete insn_map, max_uid, and call_used.
+ Insn numbers start at 1 and we have two entries in regs_live_at
+ for each insn.
+ Search for REG_NO_CONFLICT block when we see a CLOBBER insn; this
+ avoids having already seen sets to the output register.
+ Call wipe_dead_reg for anything in a REG_UNUSED note.
+ Delete references to reg_first_use.
+ Don't check for invalid birth and death here.
+ Don't call qsort if we have 0 or 1 quantities.
+ Find all registers for a quantity using reg_next_in_qty chain instead
+ of looping over all pseudos.
+ (combine_regs): Refine tests to agree with new conventions.
+ Never tie pseudos if SREG already has a quantity assigned.
+ When updating size, use reg_next_in_qty instead of looping over
+ all registers.
+ (reg_is_set): Just call reg_is_born. Where it is born depends on
+ whether we have a CLOBBER or not. Birth location is now twice
+ the insn number.
+ (reg_is_born): Handle case when a hard reg is born before the
+ current insn.
+ Show we don't know the death location.
+ (wipe_dead_reg): Parameters are now just register and an in/out flag.
+ Death locations are now twice the insn number.
+ Support hard regs that die immediately after current insn.
+ Don't make REG_UNSET notes.
+ (find_free_reg): Validate BIRTH and DEATH here.
+ We no longer have qty_clobber.
+ (post_mark_life): Eliminate CLOBBER parameter.
+ (no_conflict_p): Now passed CLOBBER at start of block. Return 0 if
+ can't find death note or if R1 is a hard register.
+
+ * m68k.md (divsi3, udivsi3): Remove patterns. Using divmodsi4 and
+ udivmodsi4 produces better code.
+ (divmodsi4, udivmodsi4): If remainder isn't needed, use divsl/divul
+ instead of divsll/divull.
+
+ * integrate.c (expand_inline_function): Remove change of March 20th.
+ Instead, expand args in two passes. First, expand all that go
+ into registers. Then do those in memory with store_expr.
+
+ * integrate.c (initialize_for_inline): Put the original copy of the
+ address into ARG_VECTOR; the new one will be modified.
+
+ * reload.c (push_reload): Handle paradoxical SUBREGs on an output
+ as well as an input.
+
+ * flow.c (mark_label_ref): Don't blow up when X is 0.
+
+ * combine.c (make_compound_operation): Fix typos; result of
+ exact_log2 is interesting if >=0.
+
+ * a29k.md (store_multiple): Allow gen_store_multiple{_no,}_bug to fail;
+ we fail if they do.
+
+ * reorg.c (emit_delay_sequence): Record that we deleted a BARRIER
+ and restore it precisely on those occaisions.

+
+ * Makefile.in (version): Run awk, not gcc, to get this value.

+Sat Mar 23 18:04:23 1991 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * cse.c (simplify_unary_operation): Add missing cases for ABS and FFS.
+
+ * alliant.md: Eliminate unneeded patterns: HImode zero_extract,
+ (set (cc0 (subreg ...))), (set (cc0) (and ...)),
+ (and (zero_extend ...) ...), shift right of 24 and 16.
+ Use alternatives to select assembler template when possible.
+ Use const_int_operand instead of immediate_operand when
+ possible to avoid explicit test for CONST_INT.
+ Write add-and-branch patterns with PLUS removed, the way combine
+ produces them.
+
+ * rtlanal.c (refers_to_regno_p): If X is a SUBREG of a hard
+ register, treat it as if it were the appropriate register.
+ CLOBBER doesn't refer to anything.
+
+ * final.c (final_scan_insn): Use prev_nonnote_insn, not PREV_INSN,
+ to find cc0-setting insn from cc0-using insn.
+
+ * global-alloc.c (find_reg): Don't look for other registers to
+ renumber unless we know that we are sharing registers.
+
+ * emit-rtl.c (end_sequence): Fix typo that prevented speedup of
+ Dec 26th from doing anything.
+
+ * toplev.c (do_abort): New function, just calls abort.
+ (main): Set lang_expand_expr to address of do_abort; abort might be
+ a macro that is more than just a function name.
+
+ * cse.c: (qty_... variables): Refined to be undefined for indices
+ less than MAX_REG. Thus, we need not intialize them at the start
+ of a basic block and can instead inialize a quantity as we create it.
+ (reg_{next,prev}_eqv): These variables will now be defined only when
+ reg_qty[N] != N and hence need not be initialized every block either.
+ (new_basic_block): Need not initialize reg_rtx for new block; the
+ only time we can inherit values from previous blocks is for hard
+ regs and it doesn't matter in that case.
+
+ * c-parse.y (yylex): Avoid use of size_t; it may not be defined.
+ Cast alloca to (char *).
+
+ * out-romp.c (update_cc): cc_status.value[12] can also be a COMPARE,
+ so use reg_overlap_mentioned_p to see if an insn that modifies a
+ register invalidates cc0.
+
+ * reorg.c (link_cc0_insns): If next insn is a SEQUENCE, the insn
+ using cc0 is the first insn in the sequence.
+ (mark_target_live_regs): Don't assume that a REG_DEAD note always
+ refers to a register.
+
+Sat Mar 23 15:35:59 1991 Richard Stallman (rms at mole.gnu.ai.mit.edu)
+
+ * reload1.c (reload_reg_free_before_p):
+ An input reload is use before an output or output address reload.
+
+ * genoutput.c (validate_insn_alternatives): New function.
+ Loop over insn's alternatives to find out how many
+ alternatives the insn pattern is to support. Verify that if
+ any alternatives are specified for a given operand that the
+ number of alternatives match the numer of alternatives for
+ this insn.
+ (gen_{insn,peephole,expand,split}): Call
+ `validate_insn_alternatives' after scanning the insn. This
+ sets up the value N_ALTERNATIVES for the insn so that
+ `process_template' can check that the number of alternitves
+ given matches the number of asm choices for `@' constructs.
+
+Sat Mar 23 08:09:57 1991 Michael Meissner (meissner at osf.org)
+
+ * dbxout.c (toplevel, dbxout_init): Instead of always using `Ltext'
+ as the label at the beginning of the text region, properly localize
+ it, so that machines which do not put leading underscores in front
+ of external names do not have a problem if the user uses `Ltext'.
+ (dbxout_init): Call text_section before putting out localized
+ `Ltext', in case ASM_FILE_START put us into a different section.
+
+Fri Mar 22 19:26:23 1991 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * a29k.md (jumpfdec): Simplify pattern to match what combine will
+ produce; remove reversed pattern.
+ * out-a29k.c (gen_reg_operand): Speed up by not calling
+ register_operand; check register number ourself.
+
+ * out-romp.c (update_cc, case CC_COMPARE): Call CC_STATUS_INIT.
+ * romp.md: In pattern that sets cc0 and copies a register to another
+ register, allow the output to be in memory so that we don't get an
+ output reload, which will cause problems.
+
+ * varasm.c (assemble_variable): Ensure DECL_INITIAL is non-zero
+ before we reference it; it might be zero if -fno-common.
+
+Fri Mar 22 16:11:35 1991 Richard Stallman (rms at mole.gnu.ai.mit.edu)
+
+ * toplev.c (abort): Don't declare if defined as macro.

+
+ * m88k.md (bxxu): Don't attempt to use bcnd.

+ * tm-m88k.h, tm-m88kdgux.h, tm-m88ksvr4.h, tm-v88r32.h: Various
+ changes to support SVR4, including support for #pragma weak.

+
+Thu Mar 21 15:46:45 1991 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * rtlanal.c (dead_or_set_p): A register is dead if it is assigned
+ via a SUBREG that references the all the words in the register.
+
+ * tm-vax.h (CONST_OK_FOR_LETTER_P): Define `I' to be constant zero.
+ (CONST_DOUBLE_OK_FOR_LETTER_P): Define `G' to be floating zero.
+ (CONST_COSTS): +/- 1 should be very cheap due to decl/inc/aob/sob.
+ (PRINT_OPERAND): Add `P', `N', `H', and `B'.
+ * vax.md: Rework many patterns to avoid C code for output template;
+ use "@" construct whenever possible.
+ Use INSN_DELETED_P.
+ Remove extendsidi2; the supplied pattern does exactly what convert_move
+ will do when the pattern is not present.
+ Use constm1_rtx to check for constant of -1.
+ Add mulsidi3 and related add-multiply pattern for emul insn.
+ Use const_int_operand as predicate instead of checking for CONST_INT.
+ Remove unneeded (set (pc) (if_then_else (ne (and ...) ...) ...))
+ patterns.
+ Merge jlbs and jbs and similarly for jlbc and jbc.
+ Remove unneeded reverse branch patterns for above insns.

+Thu Mar 21 08:16:12 1991 Michael Meissner (meissner at osf.org)
+
+ * va-mips.h (whole file): Replace with the 1.39 version of this

+ primitive support for 2.00.
+
+Wed Mar 20 18:31:42 1991 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * jump.c (duplicate_loop_exit_test): Make copy of contents of
+ register note; if it was a REG_EQUAL note, it might have been an
+ arbitrary expression and sharing it can cause problems in cse.
+
+ * rtl.def (UMULT): Remove unsigned multiply code.
+ * combine.c (subst, significant_bits): Remove code UMULT and
+ support for indicating widening multiply with different modes
+ on the MULT operation vs. its operands.

+
+ * recog.c: Include insn-attr.h.
+ (general_operand): If we have insn scheduling, don't allow paradoxical
+ SUBREGs since they can prevent scheduling memory references; they
+ aren't helpful on RISCs anyway and can cause poor register allocation.
+ * Makefile.in (recog.o): Includes insn-attr.h.
+
+ * cse.c (COST): A register only in NO_REGS isn't a specially-cheap reg.
+ (simplify_unary_operation, case {ZERO,SIGN}_EXTEND): If OP_MODE was
+ given as VOIDmode, use MODE; allow mode size of HOST_BITS_PER_INT.
+ (cse_insn): Don't make SET_SRC equal SET_DEST if doing so will cause
+ two registers to be live containing the same value.
+ (cse_end_of_basic_block): Count SETs in CALL_INSNs and JUMP_INSNs.

+ * gnulib2.c (__builtin_saveregs)[MIPS]: Go to text section.
+
+ * final.c (final_scan_insn): Don't go to text after jump-tab label.

+ (unlink_notes): Work from back-to-front instead of front-to-back.
+ (new_sometimes_live): Fix code that looks for an element already in
+ the table.
+ (schedule_block): New variable TAIL_PRIORITY used to help determine
+ max IPC of scheduled code. Also, for now we analyze (schedule) all
+ blocks, even ones which won't benfit from scheduling. This is
+ necessary to keep register live info correct, but has the
+ disadvantage of screwing *all* debug info, not just for the blocks
+ that were scheduled.
+ (update_links): Fix complicated code that was to be a simple
+ head-cons to be a simple head-cons.
+ (schedule_insns): Update REG_LIVE_LENGTH and REG_N_CALLS_CROSSED
+ after scheduling.
+
+ * sparc.md (cmpdf): Define an expand pattern for this. (Dropped by

+
+ * out-sparc.c (singlemove_string): Catch case where `sethi' can be
+ used instead of `mov'.
+
+ * gcc.texinfo (Optimize Options): Add documentation about the

+
+ * out-sparc.c (output_block_move): Use `rtx_alloc' instead of
+ `gen_rtx' to cons a CONST_INT whose INTVAL we can change.
+
+ * toplev.c (main): Recognize all -O strings (i.e. -O3, -O69), not
+ just -O and -O2.
+
+Mon Mar 18 22:30:21 1991 Richard Stallman (rms@mole.ai.mit.edu)

+
+ * m68k.md: Delete patterns now converted by combine to simpler
+ patterns or otherwise obsolete. Specifically: ZERO_EXTRACT from
+ an HImode object, setting cc0 to SUBREG or AND, umulhi3, umulsi3,
+ AND of a ZERO_EXTRACT, shifts of 24 and 16 from MEM, and patterns with
+ constants as first operand of comparison operator.
+ Remove COMPARE except as a SET_SRC.
+
+ * alliant.md, tahoe.md, rs6000.md: Remove COMPARE except as a SET_SRC.

+ * Makefile.in (combine.o): Include insn-codes.h and insn-attr.h.
+
+ * combine.c: Major rework to support many more simplifications in
+ a more regular manner and support combining three insns into two.
+ The most significant changes are the following:
+ (subst): Remove simplifications involving ZERO_EXTRACT, SIGN_EXTRACT,
+ ZERO_EXTEND, SIGN_EXTEND, AND, and shifts.
+ Call new routines below; in the case of comparisons, handle call
+ find_next_use if we need to change the comparison code or the
+ particular MODE_CC mode required.
+ No need to ever change ASHIFT to MULT here.
+ (expand_compound_operation): New function to convert
+ {ZERO,SIGN}_{EXTRACT,EXTEND} into the appropriate pair of shifts.
+ (make_compound_operation): New function to make
+ {ZERO,SIGN}_{EXTRACT,EXTEND} operations from shifts and ANDs.

+
+ * jump.c (jump_optimize): Complete last change: use expand_and result.

+ a comparison tree that is a list of nested switch statements.
+ Also, genrecog.c is now indented properly so that debugging is eased.
+ (add_to_sequence): Enforce mode on the first arg of COMPARE, comparison
+ operation, SIGN_EXTEND, and ZERO_EXTEND.

+ aligned. Use UNITS_PER_WORD-1 instead of a hard coded 3.

+ being executed and print a version number; loops instead of
+ recursion used to write out the tables; support for user using -r;
+ checking all error returns; not using the shell to start processes.

+ moved to gnulib2.c.
+
+ * Makefile.in (collect2, collect2.o): Change to use the default

+
+ * t-decstatn (CCLIBFLAGS, GNULIB2_CFLAGS): Define so that gnulib1
+ and gnulib2 are both compiled with -G 0, in case the users compiles
+ and links this way. It also fixes a bug where the constructors and
+ destructors that collect2 produces are in the big data section, but
+ gnulib2 thinks they are in the small data section, because it only
+ sees a pointer.
+ (ld): Add -f to remove old ld link to collect2, if it exists.
+
+ * t-mips (CCLIBFLAGS, GNULIB2_CFLAGS): Define so that gnulib1
+ and gnulib2 are both compiled with -G 0, in case the users compiles
+ and links this way. It also fixes a bug where the constructors and
+ destructors that collect2 produces are in the big data section, but
+ gnulib2 thinks they are in the small data section, because it only

+ (ld): Add rule to link collect2 to ld.

+
+ * xm-mips.h (alloca): If not GNU C, declare alloca to be char *.
+
+ * mips-tfile.c (add_aux_sym_tir): Move code to record bitfield size,

+ (mips_hard_regno_mode_ok): New global array to give the results
+ of HARD_REGNO_MODE_OK for each register and mode.
+ (mips_fill_delay_slot): Instead of taking the number of nops as a
+ parameter, take an enumeration, giving what kind of delay this is.
+ If the next instruction is a label, put nops before label, not
+ after. Add support for mflo/mfhi, which need 2 nops if the next
+ instruction would modify the hi/lo registers.
+ (mips_move_1word, mips_move_2words): mips_fill_delay_slot calling
+ sequence changes. Pass mflo/mfhi to schedule nops.
+ (mips_move_2words): Move DImode to/from hi and lo registers is now
+ supported.
+ (function_arg): Correctly align long long parameters, just like
+ doubles. Also correct typo in debug code. Bug report from
+ lisa@MicroUnity.com.
+ (override_options): Initialize mips_hard_regno_mode_ok. Restrict
+ int's from going in the FP registers, to limit the register
+ allocator from allocating them instead of using memory. Also, make
+ the special registers (HI, LO, FPSW) only accept full sized ints, or
+ a double int for the HI:LO combination.
+ (compute_frame_size): Don't set the initialized member until reload
+ has completed, since otherwise the information may change.
+
+ * mips.md (various): Add 64 bit integer operations for addition,
+ subtraction, negation, and, inclusive or, exclusive or, one's
+ complement, shifts, and nor. Add 32x32->64 bit support for
+ multiply, which the compiler then uses to construct 64 bit
+ multiplies.
+ (mulsi3): Break mul into it's two instructions, and schedule the
+ two nops needed for the mflo instruction. Don't allow an integer
+ multiplier anymore.
+ (ffssi2): Delete define_expand, and use a second clobber'ed register
+ to preserve the original input, instead of (clobber (match_dup 1)).
+ (movsi_ulw): Change mips_fill_delay_slot calling sequence.
+ (movdi_internal): Allow DImode move from HI/LO to/from GP registers.
+ (movdi define_split): Add a define_split to separate the two parts
+ of DImode register pairs when using GP registers.
+ (movdf define_split): Add a define_split to separate the two parts
+ of DFmode register pairs when using GP registers.
+ (mov??_internal): Change condition to call memory_operand, instead
+ of just checking for MEM, which disallows (subreg (MEM)) during
+ the intermediate parts of the compilation. Reported by
+ lisa@MicroUnity.com.
+ (negsi2): Turn back into a real insn instead of just a
+ define_expand for subsi3.
+ (one_cmplsi2): Turn back into a real insn instead of just a
+ define_expand for norsi3.
+ (andsi3, iorsi3, xorsi3): Be more liberal than the real machine, and
+ allow 32 bit constants to improve the code generated for bitfields,
+ at the expense of potentially not moving the constant out of loops.
+ (various): Add = constraint to all clobbers.
+ (fix_trunc*): Go back to old method of using two clobbers, since
+ unoptimized compiles call abort otherwise, when returning the result
+ of truncating a float as a function result.
+
+ * tm-mips.h (delay_type): New enum to express different types of
+ delay slots.
+ (mips_load_reg3, mips_load_reg4): Declarations for more registers
+ to check for needing nops. Used by multiply/divide to schedule
+ the two nops needed after mfhi/mflo if the next instruction would
+ clobber the register.
+ (CONDITIONAL_REGISTER_USAGE): If -msoft-float, disable all FP
+ registers.
+ (MASK_DEBUG_G): Add comment saying -mdebugg turns of new DImode
+ patterns, in case the code is wrong.
+ (HARD_REGNO_NREGS): All FP registers use register pairs, so that
+ SF in a GP register takes only one register, and SI in a FP
+ register takes 2.
+ (HARD_REGNO_MODE_OK): Change macro to reference the array
+ mips_hard_regno_mode_ok, which is now built in override_options.
+ (CONST_OK_FOR_LETTER_P): 'N' is now for negative numbers, 'O' is
+ an exact power of 2, and 'P' is now for positive numbers.
+ (PREFERRED_RELOAD_CLASS): If -msoft-float, never prefer a FP
+ register.
+ (PREFERRED_RELOAD_CLASS_FM): Delete, since nobody uses it.
+ (FINAL_PRESCAN_INSN): Check for mips_load_reg3 and mips_load_reg4
+ being mentioned. Also add a missing tab when more than one delay
+ slot.
+ (CONST_COSTS): Make all constant ints cost 0 to lower register
+ pressure according to Richard Kenner.
+ (RTX_COSTS): Adjust costs for DI, SF, and DF modes, and add ABS/FFS
+ costs as well.
+ (REGISTER_MOVE_COSTS): Bump costs for moving between register
+ classes, so that reload doesn't try to store int type values in the
+ floating point registers.

+ ways of specifying machines from configure. Also added
+ support for all (before it was missing a few) of the tm-*.h
+ files. It now supports the concept of guessing the vendor for
+ a given CPU type. It now supports the concept of guessing the
+ os version given the vendor and/or the CPU type. Changed the
+ default os for vax to ultrix, changed the default os for i386
+ to sco.
+
+ * collect-ld: New file. It is useful when compiling C++ programs

+
+ * mips-tfile.c (all): Change small allocation requests to use

+
+ First cut at ANSI-style exception handling (using
+ syntax and semantics of Stroustrup 2nd ed).
+ THIS IS WORK IN PROGRESS!
+ * cp-tree.h: Declare flag_ansi_exceptions.
+ * gplus.gperf: Add 'throw' (for ANSI exception handling),
+ and update private/protected/public from (old) cp-lex.c.
+ * cp-hash.h: New file, generated from gplus.gperf.
+ * cp-lex.c: #include cp-hash.h, instead of requiring
+ manual cut-and-paste when keywords are changed.
+ * cp-lex.c: Commented out some extern declarations that
+ were conflicting with inlines in cp-input.c.
+ Hooks for ANSI-style exception handling.
+ * cp-parse.y: Parse ANSI-style exception stuff.
+ * cp-decl2.c: Define new flag flag_ansi_exceptions.
+ * cp-decl2.c (finish_table): Off-by-one error in
+ calculating index type.
+ * clus-decl2.c (finish_vtable_vardecl): Add missing

+ These are heavily hacked from similar old functions.
+
+ Try to make -fdossier work better (but more work is needed).
+ (Especially, generate fewer unneeded descriptors.)
+ * cp-class.c (add_virtual_function, finish_struct): Do not
+ create a vtable just because of -fdossier.
+ * cp-gc.c: Each type points to an array of fields,
+ instead of an array of pointers to fields. Ditto for methods.
+ This saves one pointer per field or method by removing
+ unneded extra indirection. Also other tweaks to save space.
+ * cp-decl.c (init_decl_processing): Add length of
+ field and method arrays to descriptors, instead of
+ relying on NULL-termination (since we no longer have
+ the extra pointer array).
+ Make the parameter count and required count of
+ method descriptors be shorts.
+ * cp-method.c: Remove no-longer-needed functions
+ build_i_desc_overload and build_m_desc_overload.
+
+ Other C++ fixes:
+ * cp-dbxout.c (dbxout_symbol): Class types were
+ emitting only a "t" spec which made gdb unhappy.
+ Kludged it so that it once more emits "Tt".

+ info if this implementation file corresponds the the
+ type's interface, even if nothing is written.

+ if none of the words are needed.
+ (libcall_dead_p): Allow CALL to be in any part of PARALLEL.
+ Use insn_dead_p to see if SET of return register is dead; old code

+ (pushtag): Revised to clarify code used to find applicable
+ binding level for a tagname.
+ Set TYPE_CONTEXT of new tagged type so that dwarfout.c can tell
+ file-scope tagged types from non-file-scope tagged types.

+ (even incomplete ones).
+ (finish_struct, finish_enum): Don't create NULL-named
+ TYPE_DECL nodes for complete tagged types. (This is now done in

+
+ * toplev.c (compile_file): Adjust conditions under which
+ `dwarfout_file_scope_decl' is called during final traversal of
+ the chain of file-scope decls so that it is called also for
+ file-scope TYPE_DECLs.
+ (rest_of_decl_compilation): Deleted call to `dwarfout_file_scope_decl'
+ for file-scope TYPE_DECLs; call `dwarfout_file_scope_decl' instead of

+ DINFO_LEVEL_* to prevent possible confusion about meaning.
+
+ * flags.h, toplev.c: (enum debug_info_type): Renamed type from

+ of useless EXTENDED_DBX_DEBUG code).
+ (use_gdb_dbx_extensions): Make declarations conditional on
+ DBX_DEBUGGING_INFO being defined.
+
+ * out-i860.c (output_fp_move_double, find_addr_reg): Add return stmts

+ (output_delayed_branch): Fix test for CONST_INT values which must be
+ loaded in two instructions (as two halves).

+ by ASM_DECLARE_FUNCTION_SIZE in varasm.c.)
+
+ * xm-i386.h (i386): Define in case the native host compiler doesn't.
+

+
+ * cp-dem.c (cp-demangle): added support for templates, static
+ data, and the new (correct) mangling for destructors.
+
+Fri Oct 25 16:18:18 1991 Mark Eichin (eichin at tweedledumber.cygnus.com)
+
+ * cp-decl2.c: (grokclassfn): destructor names *should* contain
+ the length; otherwise, we can't tell the difference between a
+ destructor for a class whose name begins with 't' and a destructor
+ for an instance of a template class.
+
+Fri Oct 25 02:15:12 1991 Richard Stallman (rms at mole.gnu.ai.mit.edu)
+
+ * SYSCALLS.c, protoize.c: Changes from rfg.

+
+Thu Oct 24 19:21:04 1991 Richard Stallman (rms at mole.gnu.ai.mit.edu)

+
+Thu Oct 24 08:02:04 1991 Ken Raeburn (raeburn at cygnus.com)
+
+ * cp-decl.c (binding_levels_sane): New function, tests that stack
+ of binding levels is consistent. Argument provides extra
+ identification for call site, in case compiler optimizes too well.
+ If PARANOID is not set, does nothing.
+ (push_binding_level, pop_binding_level): Now functions, for easier
+ debugging. Inlined under GNU C if not PARANOID.
+ (PUSH_BINDING_LEVEL, POP_BINDING_LEVEL): Invoke functions.
+ (push_to_top_level): Use type-shadowed slots to unwind
+ IDENTIFIER_TYPE_VALUE back to top level.
+ (start_decl): When processing a template decl, shouldn't need to
+ check uses_template_parms. For methods, modify arg list to include
+ `this'. Don't set context of template. Use perm_tree_cons when
+ building members list for class template.
+ (grokdeclarator): Check "friend" flag before calling
+ globalize_nested_type. Build a method type for a function that has
+ a context.
+
+ * cp-pt.c (end_template_decl): If template has non-null context,
+ chain it off of the containing class, rather than using pushdecl.
+ (instantiate_class_template): Instantiate all the member templates
+ hanging off the class template. Also, simplify some code in the
+ case where setup_parse is 0.
+ (tsubst): Check for several common values that won't be modified by
+ substitutions.
+ (tsubst, case FUNCTION_DECL): Don't return type passed if it has a
+ non-null context that might need fixing. Process that context while
+ building up the new decl node; use it to notify build_decl_overload
+ that we've got a method rather than a function.
+ (tsubst, case METHOD_TYPE): Handle like FUNCTION_TYPE; enhance that
+ case to handle TYPE_METHOD_BASETYPE when set.
+ (unify): Increment value pointed to by nsubsts, not the pointer
+ itself.
+ (do_pending_expansions): Method context is in DECL_CONTEXT, not
+ DECL_CLASS_CONTEXT.
+
+ * cp-lex.c (do_identifier): Don't try looking up fields in base
+ classes of UNINSTANTIATED_P_TYPE.
+
+ * cp-parse.y (primary): Call require_complete_type only for

+ except for node creation changed to use these.
+ * cp-tree.def: Updated comments for these node types.
+
+ * cp-pt.c (uses_template_parms): Handle ADDR_EXPR.
+ (end_template_decl): For function with non-null context, pop class
+ binding level.

+ reg-reg copy with overlapping registers correctly.
+
+ * out-rs6000.c (ccr_bit, case NE): Fix typo in bit number.
+ (output_epilog): Must restore stack using backchain if alloca called.
+
+ * romp.md, rs6000.md (extendxxyy2, zero_extendxxyy2): Use DEFINE_EXPAND
+ to force operand to register; DEFINE_INSN allows memory (better cse).
+
+ * rs6000.md (ffssi2): New patterns.
+ (maskir): Add patterns to use maskir instructions.
+
+ * tm-a29kunix.h (TARGET_DEFAULT, CPP_SPEC): Default to 29050.
+
+ * tm-rs6000.h (LINK_SPEC): Add -bnodelcsect.
+ (HARD_REGNO_MODE_OK): Delete kludge that didn't allow DImode in reg 31
+ and TImode in 29-31; the bug was fixed elsewhere.
+
+Wed Oct 23 17:48:43 1991 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * combine.c (try_combine): If an insn doesn't match, check for case
+ where first SET's result isn't used; previously only checked second.
+
+ * combine.c (try_combine): When we substitute into a COMPARE, check
+ SELECT_CC_MODE to see if we should try to change the mode of the
+ COMPARE and its result.
+
+Wed Oct 23 16:38:26 1991 Torbjorn Granlund (tege at hal.gnu.ai.mit.edu)
+
+ * gnulib2.c (__ashrdi3): Compute sign extension shift count from

+ multiple definitions.
+
+Tue Oct 22 15:06:31 1991 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
+
+ * reload1.c (reload): For now, we must always have a frame pointer

+
+ * cse.c (insert_regs): Don't make new quantity for the register in
+ a SUBREG.
+ (merge_equiv_classes): Don't invalidate the register inside a SUBREG.

+ * optabs.c (add_equal_note): New function.
+ (expand_binop): Delete some obsolete, turned-off code.
+ Use GET_RTX_CLASS to see if operator is commutative.

+ redo the operation without our target.
+ In multi-word cases, don't allow TARGET to be the same as an input.
+ (expand_unop): Allow operation to fail.
+ Call add_equal_note and allow failure, like in expand_binop.
+ In multi-word case, don't allow TARGET to be OP0.

+
+ * optabs.c (expand_float, expand_fix): In cases when we will jump,
+ ensure we call emit_queue before protect_from_queue.
+ Eliminate redundant calls to protect_from_queue and force_non_mem.
+
+ * reorg.c (steal_delay_list_from_target): Don't take an insn from
+ the fallthrough thread of an annulled branch insn.

+
+Sun Oct 20 04:37:21 1991 Michael Tiemann (tiemann at cygnus.com)
+
+ * cp-decl.c (grokfndecl): Use DECL_NAME, not DECLARATOR at end of

+
+ * cp-cvt.c (convert_pointer_to): Test if PARENT is TREE_VEC
+ before testing IS_AGGR_TYPE.

+
+ * tm-mips.h (GP_REG_OR_PSEUDO_P): New macro to make sure a reg or

+ can't handle it.
+
+Sat Oct 19 08:26:13 1991 Ron Guilmette (rfg at ncd.com)
+
+ * tree.h: Fix spelling error in comment.
+
+ * tree.def, cp-parse.y: Change comments that refer to LET_STMT nodes to
+ refer to BLOCK nodes.
+
+ * gcc.c, gen*.c: Declare as static objects that aren't referenced
+ outside the file they are in.
+ (xrealloc, xmalloc): Functions return char *, not int.
+ (main): Add missing returns (in unreachable code) to avoid warnings
+ when compiled with -Wreturn-type.

+
+ * jump.c (unsigned_condition, signed_condition): New functions.
+
+ * configure (vax): Set tm_file to tm-vax.h so "configure vax-dec-bsd"
+ works.
+
+ * combine.c (subst, case PLUS, MINUS): Remove some simplifications
+ from here.
+ * cse.c (simplify_binary_operation, case PLUS, MINUS): Put these
+ simplifications here.
+ Strip off CONST when looking for some simplifications.

+
+ * cp-parse.y (stmts): Fix parsing rules to match C++ semantics

+
+Thu Oct 17 19:31:15 1991 Ken Raeburn (raeburn at cygnus.com)
+
+ * cp-pt.c (tsubst): For NEGATE_EXPR, call build1, not build.
+ Handle NOP_EXPR likewise.
+ (unify, case TEMPLATE_CONST_PARM): Copy value to permanent obstack.
+
+ * cp-method.c (PARM_CAN_BE_ARRAY_TYPE): If not already defined,
+ define it to be 1.
+ (build_overload_name): Test to see if it's nonzero, rather than
+ whether it's defined; this permits compilation options to disable
+ it, but leave it enabled by default. Add one to the array size,
+ since the value retrieved appears to be the maximum index, not the
+ true array size.
+
+Thu Oct 17 19:15:37 1991 Mark Eichin (eichin at tweedledumber.cygnus.com)
+
+ * cp-pt.c (instantiate_class_template): has an argument to
+ indicate whether to setup for parsing or not. (All existing cases
+ did a feed input, but if we are trying to set up intermediate nodes
+ while waiting for the parser to return to a template_instantiate
+ site we need to suppress the parsing part of it, which will get
+ redone later.)
+ (tsubst): under case UNINSTANTIATED_P_TYPE, actually instantiate any
+ class templates that are needed for function return values, and set
+ them up as pending templates to be run later.
+
+ * cp-parse.y (primary): since build_x_function_call doesn't
+ require a complete type any more in certain cases, we instantiate
+ any pending templates and then require_complete_type on the
+ remainder.
+
+ * cp-typeck.c (build_function_call_real): added an argument to
+ optionally skip the require_complete_type... implicit template
+ instantiation has to be postponed, so we won't get a complete type
+ until the parser can grab it.
+
+ * cp-call.c (build_overload_call_real): added an argument do
+ allow choice of build_function_call_maybe or build_function_call
+ based on whether we thought we would require a complete type out of
+ build_function_call.
+
+Wed Oct 16 09:06:57 1991 Tom Wood (wood at dg-rtp.dg.com)
+
+ * c-decl.c (store_parm_decls): Fix and disable recording the arg
+ type list for the function indicating the number of arguments.
+ * c-typeck.c (self_promoting_args_p): Allow the arg type to be null.
+
+ * expmed.c (store_bit_field, extract_bit_field): Add checks for
+ MEM_IN_STRUCT_P if the structure reference is a MEM.
+
+Tue Oct 15 18:37:50 1991 Ken Raeburn (raeburn at cygnus.com)
+
+ * cp-call.c (build_overload_call): If template match fails, still
+ set function field of candidate structure, and set bad_arg field to
+ new magic number -4 to indicate failed type unificiation.
+
+ * cp-class.c (add_method): Call make_function_rtl only if not
+ processing a template declaration.
+
+ * cp-tree.def: New node type, UNINSTANTIATED_P_TYPE, for
+ parameterized types that haven't had parameters filled in yet.
+ Looks like a type node.
+
+ * cp-decl.c (struct binding_level): New flag indicating any name
+ should be accepted when looked up at this level. This is a kludge
+ to try to deal with methods of parameterized types.
+ (declare_uninstantiated_type_level): Set it.
+ (uninstantiated_type_level_p): Return it.
+ * cp-class.c (pushclass): If the "class" type is
+ UNINSTANTIATED_P_TYPE, flag it in the new binding level.
+
+ * cp-decl.c (push_overloaded_decl): New argument to indicate
+ whether the decl should be forgotten when the current level is
+ exited. Callers changed.
+ (push_overloaded_decl_top_level): Ditto.
+ (dont_forget_overload): Deleted.
+ (push_overloaded_decl_1): New fn; like push_overloaded_decl, but
+ never forgets. Intended only for use by auto_function macro.
+ (auto_function): Use it.
+
+ * cp-decl.c (print_binding_level): Print type-shadowed field at
+ each level. Skip fields with no values.
+
+ * cp-decl.c (adjust_type_value): Use SET_IDENTIFIER_TYPE_VALUE,
+ not set_identifier_type_value.
+
+ * cp-decl.c (pushdecl): Undo Oct 4 back-out of previous change.
+ Set type value of name of passed decl, instead of name of type in
+ passed decl.
+ (pushdecl_top_level): Search type-shadowed fields of outer binding
+ levels, munging outermost one if found to cause it to "restore" the
+ new global value.
+
+ * cp-decl.c (push_overloaded_decl): Don't punt second or later
+ templates of a given name.
+
+ * cp-decl.c (start_decl): Template-handling code moved up, to
+ cope better with variable declarations. Don't check for incomplete
+ type or constructor requirements when processing template.
+
+ * cp-decl2.c (build_push_scope): If passed error mark node, just
+ return it.
+ (constructor_name): Handle UNINSTANTIATED_P_TYPE.
+
+ * cp-lex.c (identifier_type): Don't return PTYPENAME for function
+ template name.
+
+ * cp-method.c (report_type_mismatch): New magic bad-arg value -4
+ indicates type unification failure.
+ (build_overload_name, case UNINSTANTIATED_P_TYPE): Handle like other
+ template-related types that shouldn't get visibility outside the
+ compiler.
+
+ * cp-parse.y (template_type): Use IDENTIFIER_TYPE_VALUE from
+ name, if expansion doesn't happen.
+ (tmpl.1, tmpl.2): Now type <ttype>. Value is null or return value
+ from instantiate_class_template.
+ (template_instantiation): Always put copy of decl in global scope.
+ Use pushdecl_top_level instead of setting IDENTIFIER_GLOBAL_VALUE
+ slot.
+ (LC): If type has been or is being defined, push a new type with the
+ same name, to avoid conflict.
+ (try_for_typename): New type <itype>. Value is non-zero iff type to
+ be pushed uses no template parms and isn't error_mark_node.
+ (scoped_id): Return error_mark_node for template parameter uses, and
+ leave error_mark_node alone. Only pop class if try_for_typename
+ value is non-zero.
+ (scoped_typename): Ditto.
+
+ * cp-pt.c (end_template_decl): If template decl/class head arg is
+ null, punt. For non-type templates that didn't come in as template
+ decls, clear public flag. Such cases shouldn't arise any more; just
+ put in abort call for now until we're sure. Comment out code for
+ forcibly removing temporary values of template type parms; Michael
+ broke the code and fixed the original problem. Handle error case
+ where decl to be pushed might be null.
+ (coerce_template_parms): Handle arg list as TREE_VEC as well as
+ TREE_LIST. If arg list uses template parms, return
+ UNINSTANTIATED_P_TYPE node.
+ (uses_template_parms, case UNINSTANTIATED_P_TYPE): Return 1.
+ (instantiate_class_template): Now returns tree -- error_mark_node or
+ NULL_TREE or class type; callers and decls changed. Assign
+ TYPE_NAME field when building new RECORD_TYPE and TYPE_DECL nodes.
+ Don't need to do extra poplevel any more.
+ (tsubst): Handle UNINSTANTIATED_P_TYPE, MINUS_EXPR, PLUS_EXPR,
+ NEGATE_EXPR.
+ (undo_template_name_overload): Don't need to explicitly clear type
+ field any more.
+ (overload_template_name): Push a TYPE_DECL, instead of explicitly
+ setting type value field.
+ (end_template_instantiation): Don't need to pop a level any more.
+ (reinit_parse_for_template): Throw away saved block for null or
+ error template node.
+ (type_unification): Handle variadic functions, and functions with
+ default values for arguments.

+ * cplus-decl.c (lookup_name): Prefer finding typenames to overloaded

+
+ * All cplus-* files: Change the representation of the C++
+ inheritance lattice for types. There is no longer such a thing as a
+ classtype_variant. Instead, types all have their own lattices
+ accessed via their CLASSTYPE_ASSOC field.
+
+ * cplus-tree.h (lang_type): Delete fields OFFSET,
+ MAIN_CLASS_VARIANT, NEXT_CLASS_VARIANT, VIA_PUB_OR_VIRT.
+ Rename field AS_ID_LIST to ID_AS_LIST, since it's a list.
+ (CLASSTYPE_AS_ID_LIST): Renamed to CLASSTYPE_ID_AS_LIST.
+ Add field ASSOC_AS_LIST, which is a TREE_LIST whose TREE_VALUE is
+ the assoc for the type.
+ (CLASSTYPE_VIA_*, SET_CLASSTYPE_VIAS): Deleted.
+ (CLASSTYPE_OFFSET*): Deleted.
+ (CLASSTYPE_N_BASECLASSES): Now uses type's assoc. TYPE_BASETYPES
+ field is unused. Next change will make TYPE_BASETYPES hold the
+ assoc field.
+ (CLASSTYPE_VBASE_SIZE): Use slot in TYPE_LANG_SPECIFIC instead of
+ sneaking it into the TREE_TYPE field of the basetypes.
+
+ (ASSOC_TYPE): Deleted. Now use ASSOC_VALUE everywhere.
+ (ASSOC_{BASETYPE,BASETYPES}): New macros. Both are operations on
+ assocs and return assocs.
+ (CLASS_ASSOC_BASETYPE): New macro. This performs roughly the same
+ function that CLASSTYPE_BASECLASS used to, but it retains no assoc
+ info in the type it returns.
+ (ASSOC_NEXT_ASSOC): New macro used for traversing assoc chains built
+ up by search routines.
+ (ASSOC_VIA_{PUBLIC,VIRTUAL}): New macros for accessing inheritance
+ information. CLASSTYPE_VIA_{PUBLIC,VIRTUAL} no longer used.
+ (ASSOC_CID): New macro.
+
+ (DECL_ANON_UNION_ELEM): Deleted. Now anonymous union decls are
+ distinguished as FIELD_DECLs with NULL DECL_NAMEs and UNION_TYPE
+ types.
+
+ (DERIVED_FROM_P): New macro. Change calls that testing inheritance
+ relationships (get_base_type and get_base_distance) to use this macro.
+
+ * cplus-type2.c (basetype_or_else): Change interface to use/return an
+ assoc instead of a type. Change name to base_assoc_or_else.
+
+ * cplus-tree.c (build_classtype_variant): Deleted.
+ (copy_type_lang_specific): Deleted.
+ * all cplus-* files: Everything that used to use CLASSTYPE_OFFSET on
+ types now uses ASSOC_OFFSET on assocs.
+
+ * cplus-class.c (propagate_basetype_offsets): Change interface to use
+ assocs instead of types. Change name to propagate_assoc_offsets.
+ * cplus-search.c (get_base_type): Ditto; name changed to
+ get_base_assoc.
+
+ * cplus-cvt.c (convert_pointer_to): Change interface to use an assoc

+ been visited.

+ ASSOC_BASEINIT_MARKED instead of CLASSTYPE_MARKED6.
+ (finish_base_struct): New argument ASSOCS is the list of assocs that
+ describe the basetypes of T.
+
+ * cplus-tree.c (make_lang_type): Always initialize
+ CLASSTYPE_VBASE_SIZE to integer_zero_node. To test if a class has
+ virtual baseclasses, test CLASSTYPE_VBASECLASSES, not
+ CLASSTYPE_VBASE_SIZE.
+
+ * cplus-class.c (finish_struct): Rewritten to use assocs instead of
+ types where appropriate.
+
+ * cplus-search.c (get_base_distance): Change interface to use assocs
+ or types. Also, PATH_PTR argument is now an assoc chain, not a
+ TREE_LIST. Algorithm to find leftmost path is now more efficient.
+ (compute_visibility): Uses assoc chain instead of TREE_LIST of
+ types.
+ (recursive_bounded_basetype_p): New function.
+ (dfs_walk, dfs_* functions): Change to be called with assocs instead
+ of types.
+ (breadth_first_search, all bfs_*): Ditto.

+ on assoc chains.
+
+ * cplus-class.c (build_vtable, prepare_fresh_vtable,
+ modify_vtable_{entries,entry},): Change interfaces to use assocs
+ instead of types. Use macro ASSOC_VTABLE_PATH_MARKED on the assocs
+ instead of CLASSTYPE_MARKED3. Use macro ASSOC_NEW_VTABLE_MARKED on
+ the assocs instead of CLASSTYPE_MARKED4.
+
+ * cplus-dbxout.c: Now needs to know more about assocs. When assocs
+ are put in the TYPE_BASETYPEs field, it should not need to know
+ about lang_type.
+
+ * cplus-decl.c (xref_tag): Rewritten to build proper assoc lists. No
+ longer builds basetype lists.
+ (finish_function): Make `flag_no_inline' really take effect.
+
+ * cplus-tree.c (make_assoc): Changed for new assoc structure. The
+ fields in assocs are now: VALUE (pointer to TYPE that this assoc is
+ for), OFFSET (the byte offset of this basetype in the whole object),
+ VTABLE (the virtual function table that should be used to initialize
+ objects controlled by this assoc), VIRTUALS (the virtual functions
+ to use for initializing VTABLE), BASETYPES (a TREE_VEC of basetypes
+ that this assoc has, or NULL_TREE if none), NEXT_ASSOC (a temporary
+ slot used to point to the next assoc in an assoc chain),
+ VIA_{PUBLIC,VIRTUAL} bits saying whether this assoc is a basetype of
+ its parent via public or virtual inheritance.
+
+ * cplus-ptree.c (print_lang_type): Modified as necessary to cope with
+ new inheritance structure.
+
+ * cplus-search.c (get_base_type_1): This function was unused and
+ wrong. Deleted.
+
+ * cplus-tree.c (layout_basetypes): Take new arg ASSOCS. Layout the
+ basetypes my modifying the assocs, not the types.
+ (layout_vbasetypes): Ditto.
+
+ * all cplus-* files: Removed dead code, unused variables, and change
+ asserts where appropriate.
+
+ * all cplus-* files: DECL_VIRTUAL_P is no longer used as a truth test
+ for whether or not a function is virtual. Use a test for non-NULL
+ DECL_VINDEX instead.

+
+ * expr.c (c_strlen): New function; determines strlen of string const.

+ and save it as the function argument list. Call build_lang_decl
+ instead of build_decl, instead of duplicating the extra work it does.
+ Set `overloaded' flag to 1. Call dont_forget_overload, so the
+ template decl won't get discarded.
+ Also deleted some commented-out code.
+
+ * cplus-pt.c (uses_template_parms, cases VAR_DECL, FUNCTION_DECL):
+ Give a warning if template parms are only used in places where they
+ can't be resolved (e.g., return types or global or fixed-class

+
+ * genemit.c (gen_expand, main): Change FAIL macro to be a simple

+
+ * cplus-except.c (cplus_expand_start_except): Set up variables
+ `current_exception_name_as_rtx' and `current_exception_parms_as_rtx'.
+ These variables are used to factor out calls to `expand_assignment'
+ and allow instead calls to `emit_move_insn', which takes about 1/2x

+
+ * cplus-class.c (add_virtual_function): Memoize the first 256
+ virtual function table index nodes (0x80000001, 0x80000002, etc.).

+ arguments.
+

+ will be.
+ (mostlyclean): Add missing -f to rm.

+
+ * mips-tfile.c (toplevel, main): Add -I file option, which renames

+ in case config.h defines some macros obstack.h uses such as
+ __PTR_TO_INT.
+
+Tue Jul 23 13:15:43 1991 Richard Stallman (rms at mole.gnu.ai.mit.edu)

+ this to take place, even if the value is ignored by the caller.
+
+ * tm-decstatn.h (SIZE_TYPE): Define this to be "unsigned int".
+
+ * emit-rtl.c (try_split): If `split_insns' actually returns a SEQ
+ which is isomorphic to PAT, return TRIAL.
+
+ * out-sparc.c (eligible_for_epilogue_delay): FP register moves are
+ only eligible for leaf-function epilogue delay slots.
+
+Tue Jul 23 11:52:50 1991 Michael Meissner (meissner at geech.gnu.ai.mit.edu)
+
+ * dbxout.c (dbxout_symbol): Correct typo in getting static member

+

+
+Mon Jul 22 02:37:23 1991 Michael Tiemann (tiemann at pogo.gnu.ai.mit.edu)
+
+ * version.c: Bumped to 1.94 because of significant changes to
+ cplus-* files.
+
+Sun Jul 21 18:45:57 1991 Richard Stallman (rms at mole.gnu.ai.mit.edu)
+
+ * toplev.c (rest_of_compilation):
+ Save and restore DECL_INITIAL if we use save_for_inline_copying.
+ * integrate.c (save_for_inline_copying): Really copy DECL_INITIAL.
+ Calling integrate_decl_tree doesn't do it; deleted that call.

+ (addsi3): Don't use lea for three operand add if -m486.
+ (ashlsi3): Don't use lea for shift of 1 if -m486.
+ (zero_extendhisi2,zero_extendqihi2,zero_extendqisi2): If dest is

+
+ * expmed.c (store_fixed_bit_field): Pass actual bit position (including
+ offset) to get_best_mode; also limit mode size to BITS_PER_WORD.
+ Use failure of get_best_mode to indicate that field spans word
+ boundary.

+ (store_split_bit_field): Accept actual bit position, hence handing
+ bitpos > BITS_PER_WORD.

+
+Sun Jul 21 06:11:55 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
+
+ * All cplus-* files: DECL_VIRTUAL_P is no longer applied to
+ FUNCTION_DECLs. Instead, to test if a function is virtual or not,
+ it suffices to test whether its DECL_VINDEX is non-NULL. We use
+ ERROR_MARK_NODE as the placeholder for a FUNCTION_DECL we know will
+ be virtual, but for which we don't yet know the actual index.
+
+ * cplus-decl.c (define_function): Don't set up DECL_ASSEMBLER_NAME
+ until after having the chance to call through PFN. Since `pushdecl'
+ now keys off of DECL_ASSEMBLER_NAME, we don't want to create
+ inadvertent aliases between builtin and library functions.
+
+ * cplus-typeck.c (build_modify_expr): We don't need to build a
+ SAVE_EXPR for a WITH_CLEANUP_EXPR.

+ Return 0 if NON_SAVING_SETJMP && `setjmp' is called in function.
+
+ * tm-i386v.h (NON_SAVING_SETJMP): New macro.
+ (FRAME_POINTER_REQUIRED): New macro.
+
+Sat Jul 20 12:25:56 1991 Richard Stallman (rms at mole.gnu.ai.mit.edu)
+
+ * tm-m88k.h (OPTIMIZATION_OPTIONS): Don't change flag_signed_bitfields.
+
+ * cccp.c (include_defaults) Use LOCAL_INCLUDE_DIR macro instead
+ of "/usr/local/include". Provide default definition.
+
+ * cccp.c (include_defaults) Added INCLUDE_DEFAULTS macro to
+ provide complete control over default include directories.
+ Delete the special case for VMS.
+ * xm-vms.h (INCLUDE_DEFAULTS): Defined.
+
+ * proto-man: Renamed from proto-unproto.1.
+
+ * final.c (final_scan_insn): Do ASM_OUTPUT_LOOP_ALIGN only for real loop.
+
+Sat Jul 20 05:34:13 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
+
+ * tree.h (tree_type): Use the MAXVAL slot for TYPE_METHODS.
+ * cplus-class.c (finish_struct): Methods are now chained with
+ TREE_CHAIN and placed in the TYPE_METHODS of their _TYPE node.
+ * cplus-dbxout.c (dbxout_type_methods): Use this fact, instead of
+ using more C++-specific knowledge.
+
+ * cplus-decl.c (init_decl_processing): Variable
+ `const_ptr_type_node' was not being initialized. Same with
+ `const_string_type_node'.
+
+ * tree.h (DECL_PRINT_NAME): Marked for death.
+ (DECL_ASSEMBLER_NAME): Changed from a char* to a tree node.
+ All front-end files changed as necessary.
+
+ * cplus-tree.h (DECL_ORIGINAL_NAME): Deleted. Now we use
+ DECL_NAME.
+ (DECL_NAME): No longer means the mangled name. Now we use
+ DECL_ASSEMBLER_NAME for that purpose.
+ All cplus-* files changed as necessary.
+
+ * cplus-tree.c (lang_printable_name): Use a ring-buffer to hold
+ printable names instead of DECL_PRINT_NAME slot of a _DECL node.
+
+ * collect2.c: #define COLLECT, and let config.h provide definition
+ of macros.

+
+ * merge in Cygnus changes...
+
+ Thu Apr 16 12:23:06 1992 Mike Stump (mrs@rtl.cygnus.com)
+
+ * cp-call.c (build_method_call): propagate const around to avoid an
+ incorrect error message. This type of fix may now be necessary in
+ other parts of the compiler. This solves all but one known const
+ problems.
+
+ Wed Apr 15 14:18:27 1992 Mike Stump (mrs@rtl.cygnus.com)
+
+ * cp-type2.c (readonly_warning_or_error): because the compiler
+ is now warning about const alot more, for a release or two,
+ lets just warn about const problems, just in case it is a compiler
+ problem and not a user problem.
+
+ * cp-cvt.c (build_up_reference): Lets get tougher on const problems
+ on COMPONENT_REFs.
+
+ Wed Apr 15 11:59:42 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
+
+ * cp-decl.c (finish_function): Check for any debug info enabled,
+ not just DBX_DEBUG.
+
+ Wed Apr 15 10:03:36 1992 Mike Stump (mrs@rtl.cygnus.com)
+
+ * cp-cvt.c (build_up_reference): Propagate const and volatile
+ down into the type so error checking works better.
+
+ Tue Apr 14 11:44:32 1992 Mike Stump (mrs@rtl.cygnus.com)
+
+ * cp-decl.c (start_decl): Shouldn't use flag_this_is_variable
+ to make what this points to const, but I don't have the heart
+ to do it right now.
+
+ * cp-decl2.c (grokclassfn): Don't use flag_this_is_variable
+ to make what this points to const.
+
+ * cp-typeck.c (convert_arguments): Let build_up_reference handle
+ const errors correctly. Removes April 10 change.
+
+ * cp-cvt.c (build_up_reference): Don't let people subvert const
+ when passing const argements to non-const functions.
+
+ * cp-tree.c (build_cplus_method_type): Don't use
+ flag_this_is_variable to make what this points to const.
+
+ From Wed Apr 1 12:00:59 1992 Chip Salzenberg (chip at tct.com)
+
+ * cp-class.c (import_export_vtable): New function to set
+ TREE_PUBLIC and/or TREE_EXTERNAL on vtables.
+ (build_vtable): Use it.
+ (prepare_fresh_vtable): Use it.
+
+ * cp-decl.c (finish_decl): Don't assume that TREE_PUBLIC means
+ "exported"; it can mean "imported". Decide with TREE_EXTERNAL.
+ (finish_function): Ditto.
+ * cp-decl2.c (write_vtable_entries): Ditto.
+ (finish_vtable_typedecl): Ditto.
+ (finish_vtable_vardecl): Ditto.

+
+ * cp-method.c (build_overload_name): Mangle 'signed char'
+ as 'Sc' (i.e. differently from 'char'!).
+
+ Fri Apr 10 17:38:04 1992 Mike Stump (mrs@cygnus.com)

+

+
+ * cp-typeck.c (build_function_call_real): Merge in a change made to
+ the C front end into the C++ front end to handle volatile functions.
+
+ Thu Apr 9 03:45:03 1992 Mark Eichin (eichin at cygnus.com)
+
+ * cp-class.c (finish_struct): sanity check before calling popclass.
+ If we're already hosed due to previous parse errors (specifically,
+ we're not inside a class anymore) just report an error rather than
+ crashing in popclass (if there wasn't a previous parse error, as the
+ message suggests, we should get reports; this closes gcc/p0000525.)
+
+ Wed Apr 8 08:56:49 1992 Mike Stump (mrs@rtl.cygnus.com)
+
+ * cp-decl.c (grokdeclarator): Fix an eichin bug introduced seconds
+ ago. Shame, he didn't put:
+
+ Workaround for p869:
+ 1) grokdeclarator (around cp-decl.c:7462) is using popclass(1)
+ uses popclass(1) to close the pushclass(3) done by
+ build_push_scope; however, it's coming around another time and
+ popping all the way out, which leads to the core dump when
+ do_friend is called from global scope (do_friend uses
+ current_class_name to figure out whose friendship it is
+ bestowing.) Current workaround: if (friendp) don't allow
+ popping all the way out. We still need to figure out how to
+ make sure it only gets called the *right* time; we also need
+ to figure out if the correct scope is being used, but that's a
+ matter of regression testing.
+
+ into a ChangeLog entry.
+
+ Wed Apr 8 01:10:44 1992 Mike Stump (mrs@rtl.cygnus.com)
+
+ * cp-decl.c: Cleanup binding_levels_sane related code. Deleted

+
+ * mips.md (movstrsi_internal): Add '&' constraint on clobbers.
+
+ * mips.c (output_movstrsi): If one of our temporary registers is
+ used as an address register, don't use it and emit a warning. This
+ is a temporary measure.

+
+ * xm-ns32k.h (memcpy, memcmp, memset): New macro definitions.

+ * sched.c (sched_analyze_2): Likewise.
+
+ * sparc.md (movdf-1): Delete special case for moving 0.0 to integer
+ registers; it resulted in poor code.
+ (fix_truncdfsi2+1): Add patterns to optimize float->fix and

+Mon Apr 13 18:20:56 1992 Mike Stump (mrs@cygnus.com)
+
+ * dwarfout.c: Add default definition for ASM_OUTPUT_ASCII

+ float and vice versa.
+
+ * emit-rtl.c (gen_lowpart_common): Rework code to truncate a

+ of linear search. Don't use bits in the IDENTIFIER node, store the

+
+ * mips.c (call_memory_operand): Delete function.
+
+ * mips.md (call* patterns): Use memory_operand instead of
+ call_memory_operand for predicates. Use the test not register and
+ not CONSTANT_ADDRESS_P instead of call_memory_operand in the
+ define_expand body to test whether the function address needs to be
+ forced to a register.
+
+ * decrose.h (HALF_PIC_DEBUG): Define as true if -mdebugb, to debug
+ the half-pic code, just like debugging normal addressing.
+ (CPP_SPEC): Use the __<name>__ form of the language macros instead

+ directive.
+ (ENCODE_SECTION_INFO): Encode function labels.
+ (ASM_OUTPUT_LABELREF): Deal with function labels.
+ (ASM_OUTPUT_REG_PUSH, ASM_OUTPUT_REG_POP): Don't do anything for
+ now; their only use (saving stuff during profiling) interacts in a
+ wierd way with required assembler directives at the start of a
+ function. Instead, do the save and restore in the function
+ prologue.
+ (hppa_encode_label): Declare.
+ * pa-hpux.h, pa-ghpux.h (TARGET_DEFAULT): Link against shared
+ libraries.
+ (LINK_SPEC): Don't link against shared libraries if debugging or

+
+ Major rework to have caller-saves emit load/store double insns when
+ possible and to avoid useless resaving of registers restored for
+ source accesses only.
+ * caller-save.c (toplevel): All arrays are multi-dimensional to
+ hold information for multiple save/restore insns. New variable
+ hard_regs_need_restore.
+ (choose_hard_reg_mode): New argument `nregs' indicating how many
+ hard registers are desired. All callers changed.
+ (init_caller_save): Change initialization to handle multiple
+ register saves. A call-used register can not be live across
+ if we can not find a single register mode to save it in.
+ (multiple register saves are optional)
+ (init_save_areas): Change initialization of regno_save_mem to
+ handle multiple register saves.

+ Set hard_regs_need_restore to hard_regs_saved after crossing
+ a call. Also recompute n_regs_saved. At the end of a basic block

+ (set_reg_live, clear_reg_live): Do the right thing for
+ hard_regs_need_restore and hard_regs_saved.
+ (restore_referenced_regs): Just return if X is a clobber.
+ Test hard_regs_need_restore to determine when to restore a hard
+ register from the save area.
+ (insert_save_restore): Now returns the number of extra registers
+ saved/restored. New argument `maxrestore' which constrains how
+ many hard registers should be restored. All callers changed.
+ Do stores of consecutive registers with double store insns if
+ possible. Else do them with single word insns. Likewise for
+ loads, except constrained by maxrestore. Set hard_regs_saved
+ and hard_regs_need_restore appropriately to minimize useless
+ saves into the save area. Test against hard_regs_need_restore
+ when trying to restore multiple regs and similarly test against
+ hard_regs_saved when storing multiple regs.

+ (ASM_FINAL_SPEC): Use %U to get the last file name created with
+ %u, rather than %u.
+ (ARG_POINTER_REGNUM): Use the hardwired register $0 as the
+ argument pointer, instead of the frame pointer, to allow the frame
+ pointer to be the same as the stack pointer after the initial
+ stack allocations. This is to allow GCC generated code to be
+ linked against MIPS shared libraries. The linker rearranges the
+ code, and needs to have a frame pointer, if used, to be the same
+ as the stack. The argument pointer is always eliminated in favor
+ of the stack pointer or frame pointer.
+ (FRAME_GROWS_DOWNWARD): Don't define this any more.
+ (STARTING_FRAME_OFFSET): Locals start after the stack area to pass

+
+ * decrose.h (ASM_FINAL_SPEC): Use %U to get the last file name
+ created with %u, rather than %u.

+
+ * cp-parse.y (print_parse_statistics): don't reference TOKEN_LENGTH

+
+ Wed Jul 22 17:41:08 1992 Mark Eichin (eichin@cygnus.com)
+
+ * cp-parse.y (structsp): note_got_semicolon was called before

+ slots here from the FINAL_PRESCAN_INSN macro.
+
+ * mips.md (andsi3, iorsi3, xorsi3): Make the constraints match
+ the real machine (the predicate still is more general in order
+ to optimize bitfields at the expense of not CSE'ing large
+ constants used in logical ops, and making reload load it into

+ more.
+
+ * varasm.c (decode_reg_name): If `memory' return -4.
+
+ * stmt.c (expand_asm_operands): If `memory' is used as a clobbered
+ register, emit a (clobber (const_int 0)) to force the compiler not
+ to cache memory values in registers across the assembly
+ instruction(s).
+
+ * mips-tfile.c (read_line): Semicolons within strings are not
+ counted as statement separators.
+
+ * collect2.c (scan_prog_file, OSF/rose case): Cast pointer arguments
+ to bcopy to generic * to avoid warnings.

+
+ convex.md: Add scheduling info.
+ (movxx): One of the operands must be a register.

+ const_double by doing two immediate loads. This is not superior
+ to loading it from memory, and can be worse, so LEGITIMATE_CONSTANT_P
+ still rejects these constants, but the patterns are still useful
+ so rtx folding can produce arbitrary results.
+ (floatunsdidf, floatunsdisf): Add patterns that avoid double rounding.
+ (floatunssidf, floatunssisf): Add patterns that mimic gcc's default
+ method, to keep SI cvts from promoting to the above DI cvts.
+ (fix_truncdfsi2): Use cvtd.l even if cvtd.w is available -- on c34
+ cvtd.w is microcoded and slower.
+ (addqi3, subqi3, mulqi3): can do immediate with word insn.
+ (subsi3): use sub/neg to get reverse subtract (reduces reg shuffling).
+ (udivsi3): give up on having sign_expand_binop do this; people keep
+ breaking it. Manually extend unsigned SI to signed DI, then divide.
+ (xshfxx3): The options rank differently on different machines, so
+ spell them all out and enable the appropriate ones under TARGET_Cxx.
+ (sqrtxx2): Put under flag_fast_math.
+ (sinxx2, cosxx2): I don't know why these exist, but they do, so supply
+ them. The other microcoded intrinsics are in convex math.h.
+ (txtxx): Remove, no longer necessary.
+ (cmpdi): Add alternative to fake "eq.l #0,sk" with "neg.l sk,scratch".
+ (cmpqi): Omit, seems to produce marginally better cse than the old way.
+ (cmpsf): Avoid compare against 0.0 in ieee mode, since -0.0 is
+ possible and would confuse old ucode.
+ (movstrsi): Add.
+ (anon): Add patterns to pick up on dbra optimizations and implement the
+ sub/test part. (This optimizes out the compare against 0.)
+ (call, call_value): Use _pop form instead, and let convex.c replace
+ the pushes with fp stores.
+ (end): Put local variable list back.
+
+ convex.c (init_convex): New. Fill in tables used by convex.h.
+ (psw_disable_float): New. Turn off float exception enables to
+ make the environment more ieee-like.
+ (set_cmp): Change name to output_cmp.
+ (gen_cmp): Change name to output_condjmp. Add handling for
+ `neg.x' as a fake `eq.x #0' and for optimized-out compares
+ that read the carry of a preceding decrement.
+ (simplify_for_convex): New. Replace addr-(-const) with
+ addr+const so /bin/as will like the notation.
+ (expand_movstr): New. Generate pipelined load/store sequence.
+ (asm_declare_function_name): New. Output arg count for debuggers.
+ (print_operand): Moved from convex.h. Add %u and %v to fetch
+ subwords of a CONST_DOUBLE, %z to use in replacing shift by mul.
+ (print_operand_address): Moved from convex.h.
+ (outfloat): New, call REAL_VALUE_TO_DECIMAL.
+ (replace_arg_pushes): New. Replace sp by fp if possible; this does
+ not allow us to get rid of sp but stores are faster than pushes on
+ new machines.
+ (emit_ap_optimizations): New. Do simple live analysis of arg pointer
+ register and eliminate dead reloads.
+
+ math-convex.h: removed.
+ fixinc.convex: new file.

+
+ * cp-method.c (build_overload_nested_name): Use DECL_NAME instead of

+ out the context if it's an ERROR_MARK so the back-end won't die later.
+
+ * cp-type2.c (my_friendly_abort): Don't say anything like "please
+ fix above errors", just exit quietly.
+
+ * cp-lex.h (enum rid): Reordered for improved speed in grokdeclarator
+ when it does its linear search. RID_WCHAR is no longer in the
+ search path, since it's found by hand (as are RID_INT and RID_CHAR).
+ (RID_FIRST_MODIFIER): Start at RID_EXTERN now.
+
+ * cp-parse.y (overloaddef): Warn that using `overload' is an
+ anachronism.
+
+ Wed Dec 9 08:27:13 1992 Niklas Hallqvist (niklas at della.appli.se)
+
+ * cp-decl.c (init_decl_processing): Make sure the "unknown type"

+ things (like nested types).
+
+ * cp-pt.c (type_unification): Only check that ARGS is a TREE_LIST if
+ it's non-null.
+
+ These four are from Niklas Hallqvist:
+
+ * cp-search.c (compute_visibility): Use the main variant when

+
+ * cp-decl.c (grokdeclarator): Instead of an assert, return a

+
+ Wed Dec 2 15:51:34 1992 Mike Stump (mrs@cygnus.com)
+
+ * cp-call.c (build_method_call): Don't call abort for pure virtual
+ methods, instead, call the user-defined method. Addresses of pure
+ virtual methods are probably still wrong.
+
+ Wed Dec 2 14:44:41 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
+
+ * cp-call.c (convert_harshness): If parm's null for a reference (as

+
+ Tue Dec 1 18:05:20 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
+
+ * cp-decl.c (grokdeclarator): Make member initialization be a
+ warning, not an error. Only issue it if not -pedantic, since
+ grokfield will issue an error when pedantic. Only warn about
+ constant members being initialized if `-ansi' is being used.
+ (finish_decl): Only complain about uninitialized const's that aren't
+ members when acting -pedantic, since we'll have already issued the
+ error about initializing a field.
+
+ * cp-type2.c (build_functional_cast): Revert change of Nov 2,

+
+ Tue Dec 1 11:09:50 1992 Brendan Kehoe (brendan@lisa.cygnus.com)

+
+ * cp-method.c (icat): Handle an argument of `1' first, since it's
+ the most common case.
+

+
+ * c++ (-lm): Also recognize -lmath as a math library.
+
+ * c++ (first): Only shift if $first is no, on the chance we got no

+ will fake out the gcc driver into thinking we want to do something).
+
+ * cp-parse.y (paren_expr_or_null): New rule to emit an error when an
+ empty condition is used when it shouldn't.
+ (simple_if, stmt): Use it for `if', `while', and `do'.
+
+ * cp-decl.c (start_decl): If grokdeclarator returns a
+ void_type_node, return a NULL_TREE.
+
+ * cp-typeck.c (build_modify_expr_1): When calling build_opfncall for
+ `operator=', use make_node to create a plain NOP_EXPR for it to use,
+ rather than trying to pass NOP_EXPR down hoping it gets there intact.
+ (build_modify_expr): Ditto.
+ * cp-method.c (build_opfncall): Use TREE_CODE on ARG3 for a
+ MODIFY_EXPR, since it'll be coming in properly as a tree now.
+
+ Sat Nov 21 02:33:28 1992 Brendan Kehoe (brendan@cygnus.com)
+
+ * cp-init.c (expand_default_init): Clear DECL_REGISTER if we're

+
+ * Makefile.in (CPLUS_OBJS): Add error.o and cp-error.o
+

+ Add the changes to redo how we handle scoping. [Merged by bpk.]
+
+ * cp-class.c ({pop,push}_nested_class): New functions to use

+ that static entities of enclosing classes will be visible.

+ instead of plain {push,pop}class calls.

+ (grokdeclarator): Remove the {push,pop}level calls around the
+ indirect recursion occuring when groking class-local typedefs.
+ Remove the error check of such typedefs hiding other fields in the
+ same scope. Remove the pushdecl_class_level call since start_decl
+ does the work now.
+
+ Class scoping (and type value caching) redone. The new behaviour
+ is triggered by NEW_CLASS_SCOPING being defined to 1. The old
+ behavior is accomplished by defining it to the value 0. The entries
+ below describes the effective changes when NEW_CLASS_SCOPING is set
+ to non-zero.
+
+ * cp-class.c (set_class_shadows): Add prototype.
+ (previous_class_values): New variable.
+ (pushclass): Adapted to not use previous_class_type & unuse_fields.

+ (previous_class_values): Add extern decl.
+ (pop_decl_level): Don't reset IDENTIFIER_CLASS_VALUE.

+ (pushtag): Don't call set_identifier_type_value. Leave out
+ setting of IDENTIFIER_CLASS_VALUE.
+ (adjust_type_value): Removed.
+ (pushdecl): Don't call adjust_type_value.
+ (pushdecl_class_level): Call push_class_level_binding. Set the
+ type value if we're seeing a TYPE_DECL.
+ (push_class_level_binding): New function whose guts came from
+ pushdecl_class_level.
+ (globalize_nested_type): See to that both the class_shadowed and
+ type_shadowed lists in the binding stack gets updated correctly.
+ Don't call set_identifier_type_value on the DECL_NESTED_TYPENAME.
+ Clear DECL_CLASS_CONTEXT as well as DECL_CONTEXT. Install a
+ correct IDENTIFIER_{CLASS,TYPE}_VALUE if needed.
+ (grokdeclarator): Prefer pushdecl_class_level over pushtag when
+ recording a nested typedef.
+ (build_enumerator): Don't install a method-local enumerator into
+ class scope.
+ * cp-decl2.c (grokfield): Don't call set_identifier_type_value.
+ * cp-search.c (closed_envelopes): New list containing information
+ of what decls should be pushed when entering a class scope.
+ (dfs_pushdecls): Build and maintain the closed_envelopes list
+ instead of managing the IDENTIFIER_CLASS_VALUEs directly.
+ (dfs_compress_decls): Adapted to recognize the envelopes
+ dfs_pushdecls has installed in the IDENTIFIER_CLASS_VALUE slots.
+ (push_class_decls): Tell overload_template_name to push the
+ template decls into class scope instead of building a new level.
+ Added code to open up the envelopes in closed_envelopes and
+ install the class/type values in the class binding contour with
+ proper shadowing.
+ (dfs_popdecls): Removed.
+ (pop_class_decls): Removed the actual decl-popping code, leaving
+ just the obstack freeing pop_search_level call. The popping is
+ automatically handled by poplevel now.
+ * cp-tree.h (NEW_CLASS_SCOPING): A new macro constant defaulted to
+ the value 1.
+ (adjust_type_value): Prototype removed.
+ (push_class_level_binding): Added prototype.

+ * cp-class.c (finish_struct): Set the DECL_CONTEXT on the type we've
+ found.
+ * cp-decl.c (pushtag): Mark the TYPE_DECL as ignored when using

+ the vtable, so we're uniform with what prepare_fresh_vtable is

+ this pointer) as artificial.
+
+ * cp-init.c (do_friend): Don't allow a friend of a class that's not
+ yet been defined; instead, complain. Make sure we mark every decl
+ that comes in as being a friend of something.
+
+ * cp-decl2.c (grokclassfn): Mark the __in_chrg parameter as
+ artificial. Don't mark it as readonly, and for destructors make
+ sure the first arg in the arg_types chain has TREE_SIDE_EFFECTS set,
+ so it's seen as artificial.
+ (finish_vtable_vardecl): For dwarf debugging, make the vtable's
+ VAR_DECL node be ignored.
+
+ * cp-decl.c (redeclaration_error_message): Use comptypes to see if

+ after we've checked the qualifiers that could have been used on them.
+
+ * cp-call.c (EVIL_RETURN, QUAL_RETURN, TRIVIAL_RETURN, ZERO_RETURN):
+ Rewrite definitions to not use do/while(0), to avoid bogus warnings
+ on compilers that can't deal with a return inside it. Change all
+ uses of them to do `return FOO_RETURN'.
+
+ Tue Jul 6 13:00:44 1993 Brendan Kehoe (brendan@lisa.cygnus.com)

+ * cp-decl.c (duplicate_decls): Set GIVE_ERROR so we know where the
+ previous declaration was for empty parameter name list declarations.
+
+ * cp-class.c (finish_struct): Clean up error message about anonymous
+ classes.
+
+ * cp-class.c (finish_struct): Don't play with TAIL when we're
+ dealing with a TYPE_DECL of a RECORD_TYPE; the list continues on
+ just fine, and TAIL is only used for managing FN_FIELDS.
+
+ * cp-decl.c (pushlevel): Change cast to HOST_WIDE_INT.
+ * cp-search.c (breadth_first_search): Likewise.

+
+ * cp-decl.c (grokdeclarator): Look at the decl as a FUNCTION_TYPE

+Installing GNU CC
+*****************
+
+ Here is the procedure for installing GNU CC on a Unix system. See
+*Note VMS Install::, for VMS systems. In this section we assume you
+compile in the same directory that contains the source files; see *Note
+Other Dir::, to find out how to compile in a separate directory on Unix
+systems.
+
+ You cannot install GNU C by itself on MSDOS; it will not compile
+under any MSDOS compiler except itself. You need to get the complete
+compilation package DJGPP, which includes binaries as well as sources,
+and includes all the necessary compilation tools and libraries.
+
+ 1. If you have built GNU CC previously in the same directory for a
+ different target machine, do `make distclean' to delete all files
+ that might be invalid. One of the files this deletes is
+ `Makefile'; if `make distclean' complains that `Makefile' does not
+ exist, it probably means that the directory is already suitably
+ clean.
+
+ 2. On a System V release 4 system, make sure `/usr/bin' precedes
+ `/usr/ucb' in `PATH'. The `cc' command in `/usr/ucb' uses
+ libraries which have bugs.
+
+ 3. Specify the host, build and target machine configurations. You do
+ this by running the file `configure'.
+
+ The "build" machine is the system which you are using, the "host"
+ machine is the system where you want to run the resulting compiler
+ (normally the build machine), and the "target" machine is the
+ system for which you want the compiler to generate code.
+
+ If you are building a compiler to produce code for the machine it
+ runs on (a native compiler), you normally do not need to specify
+ any operands to `configure'; it will try to guess the type of
+ machine you are on and use that as the build, host and target
+ machines. So you don't need to specify a configuration when
+ building a native compiler unless `configure' cannot figure out
+ what your configuration is or guesses wrong.
+
+ In those cases, specify the build machine's "configuration name"
+ with the `--build' option; the host and target will default to be
+ the same as the build machine. (If you are building a
+ cross-compiler, see *Note Cross-Compiler::.)
+
+ Here is an example:
+
+ ./configure --build=sparc-sun-sunos4.1
+
+ A configuration name may be canonical or it may be more or less
+ abbreviated.
+
+ A canonical configuration name has three parts, separated by
+ dashes. It looks like this: `CPU-COMPANY-SYSTEM'. (The three
+ parts may themselves contain dashes; `configure' can figure out
+ which dashes serve which purpose.) For example,
+ `m68k-sun-sunos4.1' specifies a Sun 3.
+
+ You can also replace parts of the configuration by nicknames or
+ aliases. For example, `sun3' stands for `m68k-sun', so
+ `sun3-sunos4.1' is another way to specify a Sun 3. You can also
+ use simply `sun3-sunos', since the version of SunOS is assumed by
+ default to be version 4. `sun3-bsd' also works, since `configure'
+ knows that the only BSD variant on a Sun 3 is SunOS.
+
+ You can specify a version number after any of the system types,
+ and some of the CPU types. In most cases, the version is
+ irrelevant, and will be ignored. So you might as well specify the
+ version if you know it.
+
+ See *Note Configurations::, for a list of supported configuration
+ names and notes on many of the configurations. You should check
+ the notes in that section before proceeding any further with the
+ installation of GNU CC.
+
+ There are four additional options you can specify independently to
+ describe variant hardware and software configurations. These are
+ `--with-gnu-as', `--with-gnu-ld', `--with-stabs' and `--nfp'.
+
+ `--with-gnu-as'
+ If you will use GNU CC with the GNU assembler (GAS), you
+ should declare this by using the `--with-gnu-as' option when
+ you run `configure'.
+
+ Using this option does not install GAS. It only modifies the
+ output of GNU CC to work with GAS. Building and installing
+ GAS is up to you.
+
+ Conversely, if you *do not* wish to use GAS and do not specify
+ `--with-gnu-as' when building GNU CC, it is up to you to make
+ sure that GAS is not installed. GNU CC searches for a
+ program named `as' in various directories; if the program it
+ finds is GAS, then it runs GAS. If you are not sure where
+ GNU CC finds the assembler it is using, try specifying `-v'
+ when you run it.
+
+ The systems where it makes a difference whether you use GAS
+ are
+ `hppa1.0-ANY-ANY', `hppa1.1-ANY-ANY', `i386-ANY-sysv',
+ `i386-ANY-isc',
+ `i860-ANY-bsd', `m68k-bull-sysv', `m68k-hp-hpux',
+ `m68k-sony-bsd',
+ `m68k-altos-sysv', `m68000-hp-hpux', `m68000-att-sysv',
+ `ANY-lynx-lynxos', and `mips-ANY'). On any other system,
+ `--with-gnu-as' has no effect.
+
+ On the systems listed above (except for the HP-PA, for ISC on
+ the 386, and for `mips-sgi-irix5.*'), if you use GAS, you
+ should also use the GNU linker (and specify `--with-gnu-ld').
+
+ `--with-gnu-ld'
+ Specify the option `--with-gnu-ld' if you plan to use the GNU
+ linker with GNU CC.
+
+ This option does not cause the GNU linker to be installed; it
+ just modifies the behavior of GNU CC to work with the GNU
+ linker. Specifically, it inhibits the installation of
+ `collect2', a program which otherwise serves as a front-end
+ for the system's linker on most configurations.
+
+ `--with-stabs'
+ On MIPS based systems and on Alphas, you must specify whether
+ you want GNU CC to create the normal ECOFF debugging format,
+ or to use BSD-style stabs passed through the ECOFF symbol
+ table. The normal ECOFF debug format cannot fully handle
+ languages other than C. BSD stabs format can handle other
+ languages, but it only works with the GNU debugger GDB.
+
+ Normally, GNU CC uses the ECOFF debugging format by default;
+ if you prefer BSD stabs, specify `--with-stabs' when you
+ configure GNU CC.
+
+ No matter which default you choose when you configure GNU CC,
+ the user can use the `-gcoff' and `-gstabs+' options to
+ specify explicitly the debug format for a particular
+ compilation.
+
+ `--with-stabs' is meaningful on the ISC system on the 386,
+ also, if `--with-gas' is used. It selects use of stabs
+ debugging information embedded in COFF output. This kind of
+ debugging information supports C++ well; ordinary COFF
+ debugging information does not.
+
+ `--with-stabs' is also meaningful on 386 systems running
+ SVR4. It selects use of stabs debugging information embedded
+ in ELF output. The C++ compiler currently (2.6.0) does not
+ support the DWARF debugging information normally used on 386
+ SVR4 platforms; stabs provide a workable alternative. This
+ requires gas and gdb, as the normal SVR4 tools can not
+ generate or interpret stabs.
+
+ `--nfp'
+ On certain systems, you must specify whether the machine has
+ a floating point unit. These systems include
+ `m68k-sun-sunosN' and `m68k-isi-bsd'. On any other system,
+ `--nfp' currently has no effect, though perhaps there are
+ other systems where it could usefully make a difference.
+
+ The `configure' script searches subdirectories of the source
+ directory for other compilers that are to be integrated into GNU
+ CC. The GNU compiler for C++, called G++ is in a subdirectory
+ named `cp'. `configure' inserts rules into `Makefile' to build
+ all of those compilers.
+
+ Here we spell out what files will be set up by `configure'.
+ Normally you need not be concerned with these files.
+
+ * A file named `config.h' is created that contains a `#include'
+ of the top-level config file for the machine you will run the
+ compiler on (*note The Configuration File:
+ (gcc.info)Config.). This file is responsible for defining
+ information about the host machine. It includes `tm.h'.
+
+ The top-level config file is located in the subdirectory
+ `config'. Its name is always `xm-SOMETHING.h'; usually
+ `xm-MACHINE.h', but there are some exceptions.
+
+ If your system does not support symbolic links, you might
+ want to set up `config.h' to contain a `#include' command
+ which refers to the appropriate file.
+
+ * A file named `tconfig.h' is created which includes the
+ top-level config file for your target machine. This is used
+ for compiling certain programs to run on that machine.
+
+ * A file named `tm.h' is created which includes the
+ machine-description macro file for your target machine. It
+ should be in the subdirectory `config' and its name is often
+ `MACHINE.h'.
+
+ * The command file `configure' also constructs the file
+ `Makefile' by adding some text to the template file
+ `Makefile.in'. The additional text comes from files in the
+ `config' directory, named `t-TARGET' and `x-HOST'. If these
+ files do not exist, it means nothing needs to be added for a
+ given target or host.
+
+ 4. The standard directory for installing GNU CC is `/usr/local/lib'.
+ If you want to install its files somewhere else, specify
+ `--prefix=DIR' when you run `configure'. Here DIR is a directory
+ name to use instead of `/usr/local' for all purposes with one
+ exception: the directory `/usr/local/include' is searched for
+ header files no matter where you install the compiler. To override
+ this name, use the `--local-prefix' option below.
+
+ 5. Specify `--local-prefix=DIR' if you want the compiler to search
+ directory `DIR/include' for locally installed header files
+ *instead* of `/usr/local/include'.
+
+ You should specify `--local-prefix' *only* if your site has a
+ different convention (not `/usr/local') for where to put
+ site-specific files.
+
+ *Do not* specify `/usr' as the `--local-prefix'! The directory
+ you use for `--local-prefix' *must not* contain any of the
+ system's standard header files. If it did contain them, certain
+ programs would be miscompiled (including GNU Emacs, on certain
+ targets), because this would override and nullify the header file
+ corrections made by the `fixincludes' script.
+
+ 6. Make sure the Bison parser generator is installed. (This is
+ unnecessary if the Bison output files `c-parse.c' and `cexp.c' are
+ more recent than `c-parse.y' and `cexp.y' and you do not plan to
+ change the `.y' files.)
+
+ Bison versions older than Sept 8, 1988 will produce incorrect
+ output for `c-parse.c'.
+
+ 7. If you have chosen a configuration for GNU CC which requires other
+ GNU tools (such as GAS or the GNU linker) instead of the standard
+ system tools, install the required tools in the build directory
+ under the names `as', `ld' or whatever is appropriate. This will
+ enable the compiler to find the proper tools for compilation of
+ the program `enquire'.
+
+ Alternatively, you can do subsequent compilation using a value of
+ the `PATH' environment variable such that the necessary GNU tools
+ come before the standard system tools.
+
+ 8. Build the compiler. Just type `make LANGUAGES=c' in the compiler
+ directory.
+
+ `LANGUAGES=c' specifies that only the C compiler should be
+ compiled. The makefile normally builds compilers for all the
+ supported languages; currently, C, C++ and Objective C. However,
+ C is the only language that is sure to work when you build with
+ other non-GNU C compilers. In addition, building anything but C
+ at this stage is a waste of time.
+
+ In general, you can specify the languages to build by typing the
+ argument `LANGUAGES="LIST"', where LIST is one or more words from
+ the list `c', `c++', and `objective-c'. If you have any
+ additional GNU compilers as subdirectories of the GNU CC source
+ directory, you may also specify their names in this list.
+
+ Ignore any warnings you may see about "statement not reached" in
+ `insn-emit.c'; they are normal. Also, warnings about "unknown
+ escape sequence" are normal in `genopinit.c' and perhaps some
+ other files. Likewise, you should ignore warnings about "constant
+ is so large that it is unsigned" in `insn-emit.c' and
+ `insn-recog.c' and a warning about a comparison always being zero
+ in `enquire.o'. Any other compilation errors may represent bugs in
+ the port to your machine or operating system, and should be
+ investigated and reported.
+
+ Some commercial compilers fail to compile GNU CC because they have
+ bugs or limitations. For example, the Microsoft compiler is said
+ to run out of macro space. Some Ultrix compilers run out of
+ expression space; then you need to break up the statement where
+ the problem happens.
+
+ 9. If you are building a cross-compiler, stop here. *Note
+ Cross-Compiler::.
+
+ 10. Move the first-stage object files and executables into a
+ subdirectory with this command:
+
+ make stage1
+
+ The files are moved into a subdirectory named `stage1'. Once
+ installation is complete, you may wish to delete these files with
+ `rm -r stage1'.
+
+ 11. If you have chosen a configuration for GNU CC which requires other
+ GNU tools (such as GAS or the GNU linker) instead of the standard
+ system tools, install the required tools in the `stage1'
+ subdirectory under the names `as', `ld' or whatever is
+ appropriate. This will enable the stage 1 compiler to find the
+ proper tools in the following stage.
+
+ Alternatively, you can do subsequent compilation using a value of
+ the `PATH' environment variable such that the necessary GNU tools
+ come before the standard system tools.
+
+ 12. Recompile the compiler with itself, with this command:
+
+ make CC="stage1/xgcc -Bstage1/" CFLAGS="-g -O2"
+
+ This is called making the stage 2 compiler.
+
+ The command shown above builds compilers for all the supported
+ languages. If you don't want them all, you can specify the
+ languages to build by typing the argument `LANGUAGES="LIST"'. LIST
+ should contain one or more words from the list `c', `c++',
+ `objective-c', and `proto'. Separate the words with spaces.
+ `proto' stands for the programs `protoize' and `unprotoize'; they
+ are not a separate language, but you use `LANGUAGES' to enable or
+ disable their installation.
+
+ If you are going to build the stage 3 compiler, then you might
+ want to build only the C language in stage 2.
+
+ Once you have built the stage 2 compiler, if you are short of disk
+ space, you can delete the subdirectory `stage1'.
+
+ On a 68000 or 68020 system lacking floating point hardware, unless
+ you have selected a `tm.h' file that expects by default that there
+ is no such hardware, do this instead:
+
+ make CC="stage1/xgcc -Bstage1/" CFLAGS="-g -O2 -msoft-float"
+
+ 13. If you wish to test the compiler by compiling it with itself one
+ more time, install any other necessary GNU tools (such as GAS or
+ the GNU linker) in the `stage2' subdirectory as you did in the
+ `stage1' subdirectory, then do this:
+
+ make stage2
+ make CC="stage2/xgcc -Bstage2/" CFLAGS="-g -O2"
+
+ This is called making the stage 3 compiler. Aside from the `-B'
+ option, the compiler options should be the same as when you made
+ the stage 2 compiler. But the `LANGUAGES' option need not be the
+ same. The command shown above builds compilers for all the
+ supported languages; if you don't want them all, you can specify
+ the languages to build by typing the argument `LANGUAGES="LIST"',
+ as described above.
+
+ If you do not have to install any additional GNU tools, you may
+ use the command
+
+ make bootstrap LANGUAGES=LANGUAGE-LIST BOOT_CFLAGS=OPTION-LIST
+
+ instead of making `stage1', `stage2', and performing the two
+ compiler builds.
+
+ 14. Then compare the latest object files with the stage 2 object
+ files--they ought to be identical, aside from time stamps (if any).
+
+ On some systems, meaningful comparison of object files is
+ impossible; they always appear "different." This is currently
+ true on Solaris and some systems that use ELF object file format.
+ On some versions of Irix on SGI machines and DEC Unix (OSF/1) on
+ Alpha systems, you will not be able to compare the files without
+ specifying `-save-temps'; see the description of individual
+ systems above to see if you get comparison failures. You may have
+ similar problems on other systems.
+
+ Use this command to compare the files:
+
+ make compare
+
+ This will mention any object files that differ between stage 2 and
+ stage 3. Any difference, no matter how innocuous, indicates that
+ the stage 2 compiler has compiled GNU CC incorrectly, and is
+ therefore a potentially serious bug which you should investigate
+ and report.
+
+ If your system does not put time stamps in the object files, then
+ this is a faster way to compare them (using the Bourne shell):
+
+ for file in *.o; do
+ cmp $file stage2/$file
+ done
+
+ If you have built the compiler with the `-mno-mips-tfile' option on
+ MIPS machines, you will not be able to compare the files.
+
+ 15. Install the compiler driver, the compiler's passes and run-time
+ support with `make install'. Use the same value for `CC',
+ `CFLAGS' and `LANGUAGES' that you used when compiling the files
+ that are being installed. One reason this is necessary is that
+ some versions of Make have bugs and recompile files gratuitously
+ when you do this step. If you use the same variable values, those
+ files will be recompiled properly.
+
+ For example, if you have built the stage 2 compiler, you can use
+ the following command:
+
+ make install CC="stage2/xgcc -Bstage2/" CFLAGS="-g -O" LANGUAGES="LIST"
+
+ This copies the files `cc1', `cpp' and `libgcc.a' to files `cc1',
+ `cpp' and `libgcc.a' in the directory
+ `/usr/local/lib/gcc-lib/TARGET/VERSION', which is where the
+ compiler driver program looks for them. Here TARGET is the target
+ machine type specified when you ran `configure', and VERSION is
+ the version number of GNU CC. This naming scheme permits various
+ versions and/or cross-compilers to coexist.
+
+ This also copies the driver program `xgcc' into
+ `/usr/local/bin/gcc', so that it appears in typical execution
+ search paths.
+
+ On some systems, this command causes recompilation of some files.
+ This is usually due to bugs in `make'. You should either ignore
+ this problem, or use GNU Make.
+
+ *Warning: there is a bug in `alloca' in the Sun library. To avoid
+ this bug, be sure to install the executables of GNU CC that were
+ compiled by GNU CC. (That is, the executables from stage 2 or 3,
+ not stage 1.) They use `alloca' as a built-in function and never
+ the one in the library.*
+
+ (It is usually better to install GNU CC executables from stage 2
+ or 3, since they usually run faster than the ones compiled with
+ some other compiler.)
+
+ 16. If you're going to use C++, it's likely that you need to also
+ install the libg++ distribution. It should be available from the
+ same place where you got the GNU C distribution. Just as GNU C
+ does not distribute a C runtime library, it also does not include
+ a C++ run-time library. All I/O functionality, special class
+ libraries, etc., are available in the libg++ distribution.
+
+Configurations Supported by GNU CC
+==================================
+
+ Here are the possible CPU types:
+
+ 1750a, a29k, alpha, arm, cN, clipper, dsp16xx, elxsi, h8300,
+ hppa1.0, hppa1.1, i370, i386, i486, i586, i860, i960, m68000, m68k,
+ m88k, mips, mipsel, mips64, mips64el, ns32k, powerpc, powerpcle,
+ pyramid, romp, rs6000, sh, sparc, sparclite, sparc64, vax, we32k.
+
+ Here are the recognized company names. As you can see, customary
+abbreviations are used rather than the longer official names.
+
+ acorn, alliant, altos, apollo, att, bull, cbm, convergent, convex,
+ crds, dec, dg, dolphin, elxsi, encore, harris, hitachi, hp, ibm,
+ intergraph, isi, mips, motorola, ncr, next, ns, omron, plexus,
+ sequent, sgi, sony, sun, tti, unicom, wrs.
+
+ The company name is meaningful only to disambiguate when the rest of
+the information supplied is insufficient. You can omit it, writing
+just `CPU-SYSTEM', if it is not needed. For example, `vax-ultrix4.2'
+is equivalent to `vax-dec-ultrix4.2'.
+
+ Here is a list of system types:
+
+ 386bsd, aix, acis, amigados, aos, aout, bosx, bsd, clix, coff,
+ ctix, cxux, dgux, dynix, ebmon, ecoff, elf, esix, freebsd, hms,
+ genix, gnu, gnu/linux, hiux, hpux, iris, irix, isc, luna, lynxos,
+ mach, minix, msdos, mvs, netbsd, newsos, nindy, ns, osf, osfrose,
+ ptx, riscix, riscos, rtu, sco, sim, solaris, sunos, sym, sysv,
+ udi, ultrix, unicos, uniplus, unos, vms, vsta, vxworks, winnt,
+ xenix.
+
+You can omit the system type; then `configure' guesses the operating
+system from the CPU and company.
+
+ You can add a version number to the system type; this may or may not
+make a difference. For example, you can write `bsd4.3' or `bsd4.4' to
+distinguish versions of BSD. In practice, the version number is most
+needed for `sysv3' and `sysv4', which are often treated differently.
+
+ If you specify an impossible combination such as `i860-dg-vms', then
+you may get an error message from `configure', or it may ignore part of
+the information and do the best it can with the rest. `configure'
+always prints the canonical name for the alternative that it used. GNU
+CC does not support all possible alternatives.
+
+ Often a particular model of machine has a name. Many machine names
+are recognized as aliases for CPU/company combinations. Thus, the
+machine name `sun3', mentioned above, is an alias for `m68k-sun'.
+Sometimes we accept a company name as a machine name, when the name is
+popularly used for a particular machine. Here is a table of the known
+machine names:
+
+ 3300, 3b1, 3bN, 7300, altos3068, altos, apollo68, att-7300,
+ balance, convex-cN, crds, decstation-3100, decstation, delta,
+ encore, fx2800, gmicro, hp7NN, hp8NN, hp9k2NN, hp9k3NN, hp9k7NN,
+ hp9k8NN, iris4d, iris, isi68, m3230, magnum, merlin, miniframe,
+ mmax, news-3600, news800, news, next, pbd, pc532, pmax, powerpc,
+ powerpcle, ps2, risc-news, rtpc, sun2, sun386i, sun386, sun3,
+ sun4, symmetry, tower-32, tower.
+
+Remember that a machine name specifies both the cpu type and the company
+name. If you want to install your own homemade configuration files,
+you can use `local' as the company name to access them. If you use
+configuration `CPU-local', the configuration name without the cpu prefix
+is used to form the configuration file names.
+
+ Thus, if you specify `m68k-local', configuration uses files
+`m68k.md', `local.h', `m68k.c', `xm-local.h', `t-local', and `x-local',
+all in the directory `config/m68k'.
+
+ Here is a list of configurations that have special treatment or
+special things you must know:
+
+`1750a-*-*'
+ MIL-STD-1750A processors.
+
+ Starting with GCC 2.6.1, the MIL-STD-1750A cross configuration no
+ longer supports the Tektronix Assembler, but instead produces
+ output for `as1750', an assembler/linker available under the GNU
+ Public License for the 1750A. Contact *kellogg@space.otn.dasa.de*
+ for more details on obtaining `as1750'. A similarly licensed
+ simulator for the 1750A is available from same address.
+
+ You should ignore a fatal error during the building of libgcc
+ (libgcc is not yet implemented for the 1750A.)
+
+ The `as1750' assembler requires the file `ms1750.inc', which is
+ found in the directory `config/1750a'.
+
+ GNU CC produced the same sections as the Fairchild F9450 C
+ Compiler, namely:
+
+ `Normal'
+ The program code section.
+
+ `Static'
+ The read/write (RAM) data section.
+
+ `Konst'
+ The read-only (ROM) constants section.
+
+ `Init'
+ Initialization section (code to copy KREL to SREL).
+
+ The smallest addressable unit is 16 bits (BITS_PER_UNIT is 16).
+ This means that type `char' is represented with a 16-bit word per
+ character. The 1750A's "Load/Store Upper/Lower Byte" instructions
+ are not used by GNU CC.
+
+`alpha-*-osf1'
+ Systems using processors that implement the DEC Alpha architecture
+ and are running the DEC Unix (OSF/1) operating system, for example
+ the DEC Alpha AXP systems. (VMS on the Alpha is not currently
+ supported by GNU CC.)
+
+ GNU CC writes a `.verstamp' directive to the assembler output file
+ unless it is built as a cross-compiler. It gets the version to
+ use from the system header file `/usr/include/stamp.h'. If you
+ install a new version of DEC Unix, you should rebuild GCC to pick
+ up the new version stamp.
+
+ Note that since the Alpha is a 64-bit architecture,
+ cross-compilers from 32-bit machines will not generate code as
+ efficient as that generated when the compiler is running on a
+ 64-bit machine because many optimizations that depend on being
+ able to represent a word on the target in an integral value on the
+ host cannot be performed. Building cross-compilers on the Alpha
+ for 32-bit machines has only been tested in a few cases and may
+ not work properly.
+
+ `make compare' may fail on old versions of DEC Unix unless you add
+ `-save-temps' to `CFLAGS'. On these systems, the name of the
+ assembler input file is stored in the object file, and that makes
+ comparison fail if it differs between the `stage1' and `stage2'
+ compilations. The option `-save-temps' forces a fixed name to be
+ used for the assembler input file, instead of a randomly chosen
+ name in `/tmp'. Do not add `-save-temps' unless the comparisons
+ fail without that option. If you add `-save-temps', you will have
+ to manually delete the `.i' and `.s' files after each series of
+ compilations.
+
+ GNU CC now supports both the native (ECOFF) debugging format used
+ by DBX and GDB and an encapsulated STABS format for use only with
+ GDB. See the discussion of the `--with-stabs' option of
+ `configure' above for more information on these formats and how to
+ select them.
+
+ There is a bug in DEC's assembler that produces incorrect line
+ numbers for ECOFF format when the `.align' directive is used. To
+ work around this problem, GNU CC will not emit such alignment
+ directives while writing ECOFF format debugging information even
+ if optimization is being performed. Unfortunately, this has the
+ very undesirable side-effect that code addresses when `-O' is
+ specified are different depending on whether or not `-g' is also
+ specified.
+
+ To avoid this behavior, specify `-gstabs+' and use GDB instead of
+ DBX. DEC is now aware of this problem with the assembler and
+ hopes to provide a fix shortly.
+
+`arm'
+ Advanced RISC Machines ARM-family processors. These are often
+ used in embedded applications. There are no standard Unix
+ configurations. This configuration corresponds to the basic
+ instruction sequences and will produce a.out format object modules.
+
+ You may need to make a variant of the file `arm.h' for your
+ particular configuration.
+
+`arm-*-riscix'
+ The ARM2 or ARM3 processor running RISC iX, Acorn's port of BSD
+ Unix. If you are running a version of RISC iX prior to 1.2 then
+ you must specify the version number during configuration. Note
+ that the assembler shipped with RISC iX does not support stabs
+ debugging information; a new version of the assembler, with stabs
+ support included, is now available from Acorn.
+
+`a29k'
+ AMD Am29k-family processors. These are normally used in embedded
+ applications. There are no standard Unix configurations. This
+ configuration corresponds to AMD's standard calling sequence and
+ binary interface and is compatible with other 29k tools.
+
+ You may need to make a variant of the file `a29k.h' for your
+ particular configuration.
+
+`a29k-*-bsd'
+ AMD Am29050 used in a system running a variant of BSD Unix.
+
+`decstation-*'
+ DECstations can support three different personalities: Ultrix, DEC
+ OSF/1, and OSF/rose. To configure GCC for these platforms use the
+ following configurations:
+
+ `decstation-ultrix'
+ Ultrix configuration.
+
+ `decstation-osf1'
+ Dec's version of OSF/1.
+
+ `decstation-osfrose'
+ Open Software Foundation reference port of OSF/1 which uses
+ the OSF/rose object file format instead of ECOFF. Normally,
+ you would not select this configuration.
+
+ The MIPS C compiler needs to be told to increase its table size
+ for switch statements with the `-Wf,-XNg1500' option in order to
+ compile `cp/parse.c'. If you use the `-O2' optimization option,
+ you also need to use `-Olimit 3000'. Both of these options are
+ automatically generated in the `Makefile' that the shell script
+ `configure' builds. If you override the `CC' make variable and
+ use the MIPS compilers, you may need to add `-Wf,-XNg1500 -Olimit
+ 3000'.
+
+`elxsi-elxsi-bsd'
+ The Elxsi's C compiler has known limitations that prevent it from
+ compiling GNU C. Please contact `mrs@cygnus.com' for more details.
+
+`dsp16xx'
+ A port to the AT&T DSP1610 family of processors.
+
+`h8300-*-*'
+ The calling convention and structure layout has changed in release
+ 2.6. All code must be recompiled. The calling convention now
+ passes the first three arguments in function calls in registers.
+ Structures are no longer a multiple of 2 bytes.
+
+`hppa*-*-*'
+ There are two variants of this CPU, called 1.0 and 1.1, which have
+ different machine descriptions. You must use the right one for
+ your machine. All 7NN machines and 8N7 machines use 1.1, while
+ all other 8NN machines use 1.0.
+
+ The easiest way to handle this problem is to use `configure hpNNN'
+ or `configure hpNNN-hpux', where NNN is the model number of the
+ machine. Then `configure' will figure out if the machine is a 1.0
+ or 1.1. Use `uname -a' to find out the model number of your
+ machine.
+
+ `-g' does not work on HP-UX, since that system uses a peculiar
+ debugging format which GNU CC does not know about. However, `-g'
+ will work if you also use GAS and GDB in conjunction with GCC. We
+ highly recommend using GAS for all HP-PA configurations.
+
+ You should be using GAS-2.3 (or later) along with GDB-4.12 (or
+ later). These can be retrieved from all the traditional GNU ftp
+ archive sites.
+
+ Build GAS and install the resulting binary as:
+
+ /usr/local/lib/gcc-lib/CONFIGURATION/GCCVERSION/as
+
+ where CONFIGURATION is the configuration name (perhaps
+ `hpNNN-hpux') and GCCVERSION is the GNU CC version number. Do
+ this *before* starting the build process, otherwise you will get
+ errors from the HPUX assembler while building `libgcc2.a'. The
+ command
+
+ make install-dir
+
+ will create the necessary directory hierarchy so you can install
+ GAS before building GCC.
+
+ To enable debugging, configure GNU CC with the `--with-gnu-as'
+ option before building.
+
+ It has been reported that GNU CC produces invalid assembly code for
+ 1.1 machines running HP-UX 8.02 when using the HP assembler.
+ Typically the errors look like this:
+ as: bug.s @line#15 [err#1060]
+ Argument 0 or 2 in FARG upper
+ - lookahead = ARGW1=FR,RTNVAL=GR
+ as: foo.s @line#28 [err#1060]
+ Argument 0 or 2 in FARG upper
+ - lookahead = ARGW1=FR
+
+ You can check the version of HP-UX you are running by executing
+ the command `uname -r'. If you are indeed running HP-UX 8.02 on
+ a PA and using the HP assembler then configure GCC with
+ "hpNNN-hpux8.02".
+
+`i370-*-*'
+ This port is very preliminary and has many known bugs. We hope to
+ have a higher-quality port for this machine soon.
+
+`i386-*-linuxoldld'
+ Use this configuration to generate a.out binaries on Linux if you
+ do not have gas/binutils version 2.5.2 or later installed. This is
+ an obsolete configuration.
+
+`i386-*-linuxaout'
+ Use this configuration to generate a.out binaries on Linux. This
+ configuration is being superseded. You must use gas/binutils
+ version 2.5.2 or later.
+
+`i386-*-linux'
+ Use this configuration to generate ELF binaries on Linux. You must
+ use gas/binutils version 2.5.2 or later.
+
+`i386-*-sco'
+ Compilation with RCC is recommended. Also, it may be a good idea
+ to link with GNU malloc instead of the malloc that comes with the
+ system.
+
+`i386-*-sco3.2v4'
+ Use this configuration for SCO release 3.2 version 4.
+
+`i386-*-isc'
+ It may be a good idea to link with GNU malloc instead of the
+ malloc that comes with the system.
+
+ In ISC version 4.1, `sed' core dumps when building `deduced.h'.
+ Use the version of `sed' from version 4.0.
+
+`i386-*-esix'
+ It may be good idea to link with GNU malloc instead of the malloc
+ that comes with the system.
+
+`i386-ibm-aix'
+ You need to use GAS version 2.1 or later, and and LD from GNU
+ binutils version 2.2 or later.
+
+`i386-sequent-bsd'
+ Go to the Berkeley universe before compiling. In addition, you
+ probably need to create a file named `string.h' containing just
+ one line: `#include <strings.h>'.
+
+`i386-sequent-ptx1*'
+ Sequent DYNIX/ptx 1.x.
+
+`i386-sequent-ptx2*'
+ Sequent DYNIX/ptx 2.x.
+
+`i386-sun-sunos4'
+ You may find that you need another version of GNU CC to begin
+ bootstrapping with, since the current version when built with the
+ system's own compiler seems to get an infinite loop compiling part
+ of `libgcc2.c'. GNU CC version 2 compiled with GNU CC (any
+ version) seems not to have this problem.
+
+ See *Note Sun Install::, for information on installing GNU CC on
+ Sun systems.
+
+`i[345]86-*-winnt3.5'
+ This version requires a GAS that has not let been released. Until
+ it is, you can get a prebuilt binary version via anonymous ftp from
+ `cs.washington.edu:pub/gnat' or `cs.nyu.edu:pub/gnat'. You must
+ also use the Microsoft header files from the Windows NT 3.5 SDK.
+ Find these on the CDROM in the `/mstools/h' directory dated
+ 9/4/94. You must use a fixed version of Microsoft linker made
+ especially for NT 3.5, which is also is available on the NT 3.5
+ SDK CDROM. If you do not have this linker, can you also use the
+ linker from Visual C/C++ 1.0 or 2.0.
+
+ Installing GNU CC for NT builds a wrapper linker, called `ld.exe',
+ which mimics the behaviour of Unix `ld' in the specification of
+ libraries (`-L' and `-l'). `ld.exe' looks for both Unix and
+ Microsoft named libraries. For example, if you specify `-lfoo',
+ `ld.exe' will look first for `libfoo.a' and then for `foo.lib'.
+
+ You may install GNU CC for Windows NT in one of two ways,
+ depending on whether or not you have a Unix-like shell and various
+ Unix-like utilities.
+
+ 1. If you do not have a Unix-like shell and few Unix-like
+ utilities, you will use a DOS style batch script called
+ `configure.bat'. Invoke it as `configure winnt' from an
+ MSDOS console window or from the program manager dialog box.
+ `configure.bat' assumes you have already installed and have
+ in your path a Unix-like `sed' program which is used to
+ create a working `Makefile' from `Makefile.in'.
+
+ `Makefile' uses the Microsoft Nmake program maintenance
+ utility and the Visual C/C++ V8.00 compiler to build GNU CC.
+ You need only have the utilities `sed' and `touch' to use
+ this installation method, which only automatically builds the
+ compiler itself. You must then examine what `fixinc.winnt'
+ does, edit the header files by hand and build `libgcc.a'
+ manually.
+
+ 2. The second type of installation assumes you are running a
+ Unix-like shell, have a complete suite of Unix-like utilities
+ in your path, and have a previous version of GNU CC already
+ installed, either through building it via the above
+ installation method or acquiring a pre-built binary. In this
+ case, use the `configure' script in the normal fashion.
+
+`i860-intel-osf1'
+ This is the Paragon. If you have version 1.0 of the operating
+ system, you need to take special steps to build GNU CC due to
+ peculiarities of the system. Newer system versions have no
+ problem. See the section `Installation Problems' in the GNU CC
+ Manual.
+
+`*-lynx-lynxos'
+ LynxOS 2.2 and earlier comes with GNU CC 1.x already installed as
+ `/bin/gcc'. You should compile with this instead of `/bin/cc'.
+ You can tell GNU CC to use the GNU assembler and linker, by
+ specifying `--with-gnu-as --with-gnu-ld' when configuring. These
+ will produce COFF format object files and executables; otherwise
+ GNU CC will use the installed tools, which produce a.out format
+ executables.
+
+`m68000-hp-bsd'
+ HP 9000 series 200 running BSD. Note that the C compiler that
+ comes with this system cannot compile GNU CC; contact
+ `law@cs.utah.edu' to get binaries of GNU CC for bootstrapping.
+
+`m68k-altos'
+ Altos 3068. You must use the GNU assembler, linker and debugger.
+ Also, you must fix a kernel bug. Details in the file
+ `README.ALTOS'.
+
+`m68k-att-sysv'
+ AT&T 3b1, a.k.a. 7300 PC. Special procedures are needed to
+ compile GNU CC with this machine's standard C compiler, due to
+ bugs in that compiler. You can bootstrap it more easily with
+ previous versions of GNU CC if you have them.
+
+ Installing GNU CC on the 3b1 is difficult if you do not already
+ have GNU CC running, due to bugs in the installed C compiler.
+ However, the following procedure might work. We are unable to
+ test it.
+
+ 1. Comment out the `#include "config.h"' line on line 37 of
+ `cccp.c' and do `make cpp'. This makes a preliminary version
+ of GNU cpp.
+
+ 2. Save the old `/lib/cpp' and copy the preliminary GNU cpp to
+ that file name.
+
+ 3. Undo your change in `cccp.c', or reinstall the original
+ version, and do `make cpp' again.
+
+ 4. Copy this final version of GNU cpp into `/lib/cpp'.
+
+ 5. Replace every occurrence of `obstack_free' in the file
+ `tree.c' with `_obstack_free'.
+
+ 6. Run `make' to get the first-stage GNU CC.
+
+ 7. Reinstall the original version of `/lib/cpp'.
+
+ 8. Now you can compile GNU CC with itself and install it in the
+ normal fashion.
+
+`m68k-bull-sysv'
+ Bull DPX/2 series 200 and 300 with BOS-2.00.45 up to BOS-2.01. GNU
+ CC works either with native assembler or GNU assembler. You can use
+ GNU assembler with native coff generation by providing
+ `--with-gnu-as' to the configure script or use GNU assembler with
+ dbx-in-coff encapsulation by providing `--with-gnu-as --stabs'.
+ For any problem with native assembler or for availability of the
+ DPX/2 port of GAS, contact `F.Pierresteguy@frcl.bull.fr'.
+
+`m68k-crds-unox'
+ Use `configure unos' for building on Unos.
+
+ The Unos assembler is named `casm' instead of `as'. For some
+ strange reason linking `/bin/as' to `/bin/casm' changes the
+ behavior, and does not work. So, when installing GNU CC, you
+ should install the following script as `as' in the subdirectory
+ where the passes of GCC are installed:
+
+ #!/bin/sh
+ casm $*
+
+ The default Unos library is named `libunos.a' instead of `libc.a'.
+ To allow GNU CC to function, either change all references to
+ `-lc' in `gcc.c' to `-lunos' or link `/lib/libc.a' to
+ `/lib/libunos.a'.
+
+ When compiling GNU CC with the standard compiler, to overcome bugs
+ in the support of `alloca', do not use `-O' when making stage 2.
+ Then use the stage 2 compiler with `-O' to make the stage 3
+ compiler. This compiler will have the same characteristics as the
+ usual stage 2 compiler on other systems. Use it to make a stage 4
+ compiler and compare that with stage 3 to verify proper
+ compilation.
+
+ (Perhaps simply defining `ALLOCA' in `x-crds' as described in the
+ comments there will make the above paragraph superfluous. Please
+ inform us of whether this works.)
+
+ Unos uses memory segmentation instead of demand paging, so you
+ will need a lot of memory. 5 Mb is barely enough if no other
+ tasks are running. If linking `cc1' fails, try putting the object
+ files into a library and linking from that library.
+
+`m68k-hp-hpux'
+ HP 9000 series 300 or 400 running HP-UX. HP-UX version 8.0 has a
+ bug in the assembler that prevents compilation of GNU CC. To fix
+ it, get patch PHCO_4484 from HP.
+
+ In addition, if you wish to use gas `--with-gnu-as' you must use
+ gas version 2.1 or later, and you must use the GNU linker version
+ 2.1 or later. Earlier versions of gas relied upon a program which
+ converted the gas output into the native HP/UX format, but that
+ program has not been kept up to date. gdb does not understand
+ that native HP/UX format, so you must use gas if you wish to use
+ gdb.
+
+`m68k-sun'
+ Sun 3. We do not provide a configuration file to use the Sun FPA
+ by default, because programs that establish signal handlers for
+ floating point traps inherently cannot work with the FPA.
+
+ See *Note Sun Install::, for information on installing GNU CC on
+ Sun systems.
+
+`m88k-*-svr3'
+ Motorola m88k running the AT&T/Unisoft/Motorola V.3 reference port.
+ These systems tend to use the Green Hills C, revision 1.8.5, as the
+ standard C compiler. There are apparently bugs in this compiler
+ that result in object files differences between stage 2 and stage
+ 3. If this happens, make the stage 4 compiler and compare it to
+ the stage 3 compiler. If the stage 3 and stage 4 object files are
+ identical, this suggests you encountered a problem with the
+ standard C compiler; the stage 3 and 4 compilers may be usable.
+
+ It is best, however, to use an older version of GNU CC for
+ bootstrapping if you have one.
+
+`m88k-*-dgux'
+ Motorola m88k running DG/UX. To build 88open BCS native or cross
+ compilers on DG/UX, specify the configuration name as
+ `m88k-*-dguxbcs' and build in the 88open BCS software development
+ environment. To build ELF native or cross compilers on DG/UX,
+ specify `m88k-*-dgux' and build in the DG/UX ELF development
+ environment. You set the software development environment by
+ issuing `sde-target' command and specifying either `m88kbcs' or
+ `m88kdguxelf' as the operand.
+
+ If you do not specify a configuration name, `configure' guesses the
+ configuration based on the current software development
+ environment.
+
+`m88k-tektronix-sysv3'
+ Tektronix XD88 running UTekV 3.2e. Do not turn on optimization
+ while building stage1 if you bootstrap with the buggy Green Hills
+ compiler. Also, The bundled LAI System V NFS is buggy so if you
+ build in an NFS mounted directory, start from a fresh reboot, or
+ avoid NFS all together. Otherwise you may have trouble getting
+ clean comparisons between stages.
+
+`mips-mips-bsd'
+ MIPS machines running the MIPS operating system in BSD mode. It's
+ possible that some old versions of the system lack the functions
+ `memcpy', `memcmp', and `memset'. If your system lacks these, you
+ must remove or undo the definition of `TARGET_MEM_FUNCTIONS' in
+ `mips-bsd.h'.
+
+ The MIPS C compiler needs to be told to increase its table size
+ for switch statements with the `-Wf,-XNg1500' option in order to
+ compile `cp/parse.c'. If you use the `-O2' optimization option,
+ you also need to use `-Olimit 3000'. Both of these options are
+ automatically generated in the `Makefile' that the shell script
+ `configure' builds. If you override the `CC' make variable and
+ use the MIPS compilers, you may need to add `-Wf,-XNg1500 -Olimit
+ 3000'.
+
+`mips-mips-riscos*'
+ The MIPS C compiler needs to be told to increase its table size
+ for switch statements with the `-Wf,-XNg1500' option in order to
+ compile `cp/parse.c'. If you use the `-O2' optimization option,
+ you also need to use `-Olimit 3000'. Both of these options are
+ automatically generated in the `Makefile' that the shell script
+ `configure' builds. If you override the `CC' make variable and
+ use the MIPS compilers, you may need to add `-Wf,-XNg1500 -Olimit
+ 3000'.
+
+ MIPS computers running RISC-OS can support four different
+ personalities: default, BSD 4.3, System V.3, and System V.4 (older
+ versions of RISC-OS don't support V.4). To configure GCC for
+ these platforms use the following configurations:
+
+ `mips-mips-riscos`rev''
+ Default configuration for RISC-OS, revision `rev'.
+
+ `mips-mips-riscos`rev'bsd'
+ BSD 4.3 configuration for RISC-OS, revision `rev'.
+
+ `mips-mips-riscos`rev'sysv4'
+ System V.4 configuration for RISC-OS, revision `rev'.
+
+ `mips-mips-riscos`rev'sysv'
+ System V.3 configuration for RISC-OS, revision `rev'.
+
+ The revision `rev' mentioned above is the revision of RISC-OS to
+ use. You must reconfigure GCC when going from a RISC-OS revision
+ 4 to RISC-OS revision 5. This has the effect of avoiding a linker
+ bug.
+
+`mips-sgi-*'
+ In order to compile GCC on an SGI running IRIX 4, the "c.hdr.lib"
+ option must be installed from the CD-ROM supplied from Silicon
+ Graphics. This is found on the 2nd CD in release 4.0.1.
+
+ In order to compile GCC on an SGI running IRIX 5, the
+ "compiler_dev.hdr" subsystem must be installed from the IDO CD-ROM
+ supplied by Silicon Graphics.
+
+ `make compare' may fail on version 5 of IRIX unless you add
+ `-save-temps' to `CFLAGS'. On these systems, the name of the
+ assembler input file is stored in the object file, and that makes
+ comparison fail if it differs between the `stage1' and `stage2'
+ compilations. The option `-save-temps' forces a fixed name to be
+ used for the assembler input file, instead of a randomly chosen
+ name in `/tmp'. Do not add `-save-temps' unless the comparisons
+ fail without that option. If you do you `-save-temps', you will
+ have to manually delete the `.i' and `.s' files after each series
+ of compilations.
+
+ The MIPS C compiler needs to be told to increase its table size
+ for switch statements with the `-Wf,-XNg1500' option in order to
+ compile `cp/parse.c'. If you use the `-O2' optimization option,
+ you also need to use `-Olimit 3000'. Both of these options are
+ automatically generated in the `Makefile' that the shell script
+ `configure' builds. If you override the `CC' make variable and
+ use the MIPS compilers, you may need to add `-Wf,-XNg1500 -Olimit
+ 3000'.
+
+ On Irix version 4.0.5F, and perhaps on some other versions as well,
+ there is an assembler bug that reorders instructions incorrectly.
+ To work around it, specify the target configuration
+ `mips-sgi-irix4loser'. This configuration inhibits assembler
+ optimization.
+
+ In a compiler configured with target `mips-sgi-irix4', you can turn
+ off assembler optimization by using the `-noasmopt' option. This
+ compiler option passes the option `-O0' to the assembler, to
+ inhibit reordering.
+
+ The `-noasmopt' option can be useful for testing whether a problem
+ is due to erroneous assembler reordering. Even if a problem does
+ not go away with `-noasmopt', it may still be due to assembler
+ reordering--perhaps GNU CC itself was miscompiled as a result.
+
+ To enable debugging under Irix 5, you must use GNU as 2.5 or later,
+ and use the `--with-gnu-as' configure option when configuring gcc.
+ GNU as is distributed as part of the binutils package.
+
+`mips-sony-sysv'
+ Sony MIPS NEWS. This works in NEWSOS 5.0.1, but not in 5.0.2
+ (which uses ELF instead of COFF). Support for 5.0.2 will probably
+ be provided soon by volunteers. In particular, the linker does
+ not like the code generated by GCC when shared libraries are
+ linked in.
+
+`ns32k-encore'
+ Encore ns32000 system. Encore systems are supported only under
+ BSD.
+
+`ns32k-*-genix'
+ National Semiconductor ns32000 system. Genix has bugs in `alloca'
+ and `malloc'; you must get the compiled versions of these from GNU
+ Emacs.
+
+`ns32k-sequent'
+ Go to the Berkeley universe before compiling. In addition, you
+ probably need to create a file named `string.h' containing just
+ one line: `#include <strings.h>'.
+
+`ns32k-utek'
+ UTEK ns32000 system ("merlin"). The C compiler that comes with
+ this system cannot compile GNU CC; contact `tektronix!reed!mason'
+ to get binaries of GNU CC for bootstrapping.
+
+`romp-*-aos'
+`romp-*-mach'
+ The only operating systems supported for the IBM RT PC are AOS and
+ MACH. GNU CC does not support AIX running on the RT. We
+ recommend you compile GNU CC with an earlier version of itself; if
+ you compile GNU CC with `hc', the Metaware compiler, it will work,
+ but you will get mismatches between the stage 2 and stage 3
+ compilers in various files. These errors are minor differences in
+ some floating-point constants and can be safely ignored; the stage
+ 3 compiler is correct.
+
+`rs6000-*-aix'
+`powerpc-*-aix'
+ Various early versions of each release of the IBM XLC compiler
+ will not bootstrap GNU CC. Symptoms include differences between
+ the stage2 and stage3 object files, and errors when compiling
+ `libgcc.a' or `enquire'. Known problematic releases include:
+ xlc-1.2.1.8, xlc-1.3.0.0 (distributed with AIX 3.2.5), and
+ xlc-1.3.0.19. Both xlc-1.2.1.28 and xlc-1.3.0.24 (PTF 432238) are
+ known to produce working versions of GNU CC, but most other recent
+ releases correctly bootstrap GNU CC. Also, releases of AIX prior
+ to AIX 3.2.4 include a version of the IBM assembler which does not
+ accept debugging directives: assembler updates are available as
+ PTFs. Also, if you are using AIX 3.2.5 or greater and the GNU
+ assembler, you must have a version modified after October 16th,
+ 1995 in order for the GNU C compiler to build. See the file
+ `README.RS6000' for more details on of these problems.
+
+ GNU CC does not yet support the 64-bit PowerPC instructions.
+
+ Objective C does not work on this architecture because it makes
+ assumptions that are incompatible with the calling conventions.
+
+ AIX on the RS/6000 provides support (NLS) for environments outside
+ of the United States. Compilers and assemblers use NLS to support
+ locale-specific representations of various objects including
+ floating-point numbers ("." vs "," for separating decimal
+ fractions). There have been problems reported where the library
+ linked with GNU CC does not produce the same floating-point
+ formats that the assembler accepts. If you have this problem, set
+ the LANG environment variable to "C" or "En_US".
+
+ Due to changes in the way that GNU CC invokes the binder (linker)
+ for AIX 4.1, you may now receive warnings of duplicate symbols
+ from the link step that were not reported before. The assembly
+ files generated by GNU CC for AIX have always included multiple
+ symbol definitions for certain global variable and function
+ declarations in the original program. The warnings should not
+ prevent the linker from producing a correct library or runnable
+ executable.

+`vax-dec-ultrix'
+ Don't try compiling with Vax C (`vcc'). It produces incorrect code
+ in some cases (for example, when `alloca' is used).
+
+ Meanwhile, compiling `cp/parse.c' with pcc does not work because of
+ an internal table size limitation in that compiler. To avoid this
+ problem, compile just the GNU C compiler first, and use it to
+ recompile building all the languages that you want to run.

+ See *Note Sun Install::, for information on installing GNU CC on
+ Sun systems.

+`vax-dec-vms'
+ See *Note VMS Install::, for details on how to install GNU CC on

+
+`we32k-*-*'
+ These computers are also known as the 3b2, 3b5, 3b20 and other
+ similar names. (However, the 3b1 is actually a 68000; see *Note
+ Configurations::.)
+
+ Don't use `-g' when compiling with the system's compiler. The
+ system's linker seems to be unable to handle such a large program
+ with debugging information.
+
+ The system's compiler runs out of capacity when compiling `stmt.c'
+ in GNU CC. You can work around this by building `cpp' in GNU CC
+ first, then use that instead of the system's preprocessor with the
+ system's C compiler to compile `stmt.c'. Here is how:
+
+ mv /lib/cpp /lib/cpp.att
+ cp cpp /lib/cpp.gnu
+ echo '/lib/cpp.gnu -traditional ${1+"$@"}' > /lib/cpp
+ chmod +x /lib/cpp
+
+ The system's compiler produces bad code for some of the GNU CC
+ optimization files. So you must build the stage 2 compiler without
+ optimization. Then build a stage 3 compiler with optimization.
+ That executable should work. Here are the necessary commands:
+
+ make LANGUAGES=c CC=stage1/xgcc CFLAGS="-Bstage1/ -g"
+ make stage2
+ make CC=stage2/xgcc CFLAGS="-Bstage2/ -g -O"
+
+ You may need to raise the ULIMIT setting to build a C++ compiler,
+ as the file `cc1plus' is larger than one megabyte.
+
+Compilation in a Separate Directory
+===================================
+
+ If you wish to build the object files and executables in a directory
+other than the one containing the source files, here is what you must
+do differently:
+
+ 1. Make sure you have a version of Make that supports the `VPATH'
+ feature. (GNU Make supports it, as do Make versions on most BSD
+ systems.)
+
+ 2. If you have ever run `configure' in the source directory, you must
+ undo the configuration. Do this by running:
+
+ make distclean
+
+ 3. Go to the directory in which you want to build the compiler before
+ running `configure':
+
+ mkdir gcc-sun3
+ cd gcc-sun3
+
+ On systems that do not support symbolic links, this directory must
+ be on the same file system as the source code directory.
+
+ 4. Specify where to find `configure' when you run it:
+
+ ../gcc/configure ...
+
+ This also tells `configure' where to find the compiler sources;
+ `configure' takes the directory from the file name that was used to
+ invoke it. But if you want to be sure, you can specify the source
+ directory with the `--srcdir' option, like this:
+
+ ../gcc/configure --srcdir=../gcc OTHER OPTIONS
+
+ The directory you specify with `--srcdir' need not be the same as
+ the one that `configure' is found in.
+
+ Now, you can run `make' in that directory. You need not repeat the
+configuration steps shown above, when ordinary source files change. You
+must, however, run `configure' again when the configuration files
+change, if your system does not support symbolic links.
+
+Building and Installing a Cross-Compiler
+========================================
+
+ GNU CC can function as a cross-compiler for many machines, but not
+all.
+
+ * Cross-compilers for the Mips as target using the Mips assembler
+ currently do not work, because the auxiliary programs
+ `mips-tdump.c' and `mips-tfile.c' can't be compiled on anything
+ but a Mips. It does work to cross compile for a Mips if you use
+ the GNU assembler and linker.
+
+ * Cross-compilers between machines with different floating point
+ formats have not all been made to work. GNU CC now has a floating
+ point emulator with which these can work, but each target machine
+ description needs to be updated to take advantage of it.
+
+ * Cross-compilation between machines of different word sizes is
+ somewhat problematic and sometimes does not work.
+
+ Since GNU CC generates assembler code, you probably need a
+cross-assembler that GNU CC can run, in order to produce object files.
+If you want to link on other than the target machine, you need a
+cross-linker as well. You also need header files and libraries suitable
+for the target machine that you can install on the host machine.
+
+Steps of Cross-Compilation
+--------------------------
+
+ To compile and run a program using a cross-compiler involves several
+steps:
+
+ * Run the cross-compiler on the host machine to produce assembler
+ files for the target machine. This requires header files for the
+ target machine.
+
+ * Assemble the files produced by the cross-compiler. You can do this
+ either with an assembler on the target machine, or with a
+ cross-assembler on the host machine.
+
+ * Link those files to make an executable. You can do this either
+ with a linker on the target machine, or with a cross-linker on the
+ host machine. Whichever machine you use, you need libraries and
+ certain startup files (typically `crt....o') for the target
+ machine.
+
+ It is most convenient to do all of these steps on the same host
+machine, since then you can do it all with a single invocation of GNU
+CC. This requires a suitable cross-assembler and cross-linker. For
+some targets, the GNU assembler and linker are available.
+
+Configuring a Cross-Compiler
+----------------------------
+
+ To build GNU CC as a cross-compiler, you start out by running
+`configure'. Use the `--target=TARGET' to specify the target type. If
+`configure' was unable to correctly identify the system you are running
+on, also specify the `--build=BUILD' option. For example, here is how
+to configure for a cross-compiler that produces code for an HP 68030
+system running BSD on a system that `configure' can correctly identify:
+
+ ./configure --target=m68k-hp-bsd4.3
+
+Tools and Libraries for a Cross-Compiler
+----------------------------------------
+
+ If you have a cross-assembler and cross-linker available, you should
+install them now. Put them in the directory `/usr/local/TARGET/bin'.
+Here is a table of the tools you should put in this directory:
+
+`as'
+ This should be the cross-assembler.
+
+`ld'
+ This should be the cross-linker.
+
+`ar'
+ This should be the cross-archiver: a program which can manipulate
+ archive files (linker libraries) in the target machine's format.
+
+`ranlib'
+ This should be a program to construct a symbol table in an archive
+ file.
+
+ The installation of GNU CC will find these programs in that
+directory, and copy or link them to the proper place to for the
+cross-compiler to find them when run later.
+
+ The easiest way to provide these files is to build the Binutils
+package and GAS. Configure them with the same `--host' and `--target'
+options that you use for configuring GNU CC, then build and install
+them. They install their executables automatically into the proper
+directory. Alas, they do not support all the targets that GNU CC
+supports.
+
+ If you want to install libraries to use with the cross-compiler,
+such as a standard C library, put them in the directory
+`/usr/local/TARGET/lib'; installation of GNU CC copies all all the
+files in that subdirectory into the proper place for GNU CC to find
+them and link with them. Here's an example of copying some libraries
+from a target machine:
+
+ ftp TARGET-MACHINE
+ lcd /usr/local/TARGET/lib
+ cd /lib
+ get libc.a
+ cd /usr/lib
+ get libg.a
+ get libm.a
+ quit
+
+The precise set of libraries you'll need, and their locations on the
+target machine, vary depending on its operating system.
+
+ Many targets require "start files" such as `crt0.o' and `crtn.o'
+which are linked into each executable; these too should be placed in
+`/usr/local/TARGET/lib'. There may be several alternatives for
+`crt0.o', for use with profiling or other compilation options. Check
+your target's definition of `STARTFILE_SPEC' to find out what start
+files it uses. Here's an example of copying these files from a target
+machine:
+
+ ftp TARGET-MACHINE
+ lcd /usr/local/TARGET/lib
+ prompt
+ cd /lib
+ mget *crt*.o
+ cd /usr/lib
+ mget *crt*.o
+ quit
+
+`libgcc.a' and Cross-Compilers
+------------------------------
+
+ Code compiled by GNU CC uses certain runtime support functions
+implicitly. Some of these functions can be compiled successfully with
+GNU CC itself, but a few cannot be. These problem functions are in the
+source file `libgcc1.c'; the library made from them is called
+`libgcc1.a'.
+
+ When you build a native compiler, these functions are compiled with
+some other compiler-the one that you use for bootstrapping GNU CC.
+Presumably it knows how to open code these operations, or else knows how
+to call the run-time emulation facilities that the machine comes with.
+But this approach doesn't work for building a cross-compiler. The
+compiler that you use for building knows about the host system, not the
+target system.
+
+ So, when you build a cross-compiler you have to supply a suitable
+library `libgcc1.a' that does the job it is expected to do.
+
+ To compile `libgcc1.c' with the cross-compiler itself does not work.
+The functions in this file are supposed to implement arithmetic
+operations that GNU CC does not know how to open code for your target
+machine. If these functions are compiled with GNU CC itself, they will
+compile into infinite recursion.
+
+ On any given target, most of these functions are not needed. If GNU
+CC can open code an arithmetic operation, it will not call these
+functions to perform the operation. It is possible that on your target
+machine, none of these functions is needed. If so, you can supply an
+empty library as `libgcc1.a'.
+
+ Many targets need library support only for multiplication and
+division. If you are linking with a library that contains functions for
+multiplication and division, you can tell GNU CC to call them directly
+by defining the macros `MULSI3_LIBCALL', and the like. These macros
+need to be defined in the target description macro file. For some
+targets, they are defined already. This may be sufficient to avoid the
+need for libgcc1.a; if so, you can supply an empty library.
+
+ Some targets do not have floating point instructions; they need other
+functions in `libgcc1.a', which do floating arithmetic. Recent
+versions of GNU CC have a file which emulates floating point. With a
+certain amount of work, you should be able to construct a floating
+point emulator that can be used as `libgcc1.a'. Perhaps future
+versions will contain code to do this automatically and conveniently.
+That depends on whether someone wants to implement it.
+
+ Some embedded targets come with all the necessary `libgcc1.a'
+routines written in C or assembler. These targets build `libgcc1.a'
+automatically and you do not need to do anything special for them.
+Other embedded targets do not need any `libgcc1.a' routines since all
+the necessary operations are supported by the hardware.
+
+ If your target system has another C compiler, you can configure GNU
+CC as a native compiler on that machine, build just `libgcc1.a' with
+`make libgcc1.a' on that machine, and use the resulting file with the
+cross-compiler. To do this, execute the following on the target
+machine:
+
+ cd TARGET-BUILD-DIR
+ ./configure --host=sparc --target=sun3
+ make libgcc1.a
+
+And then this on the host machine:
+
+ ftp TARGET-MACHINE
+ binary
+ cd TARGET-BUILD-DIR
+ get libgcc1.a
+ quit
+
+ Another way to provide the functions you need in `libgcc1.a' is to
+define the appropriate `perform_...' macros for those functions. If
+these definitions do not use the C arithmetic operators that they are
+meant to implement, you should be able to compile them with the
+cross-compiler you are building. (If these definitions already exist
+for your target file, then you are all set.)
+
+ To build `libgcc1.a' using the perform macros, use
+`LIBGCC1=libgcc1.a OLDCC=./xgcc' when building the compiler.
+Otherwise, you should place your replacement library under the name
+`libgcc1.a' in the directory in which you will build the
+cross-compiler, before you run `make'.
+
+Cross-Compilers and Header Files
+--------------------------------
+
+ If you are cross-compiling a standalone program or a program for an
+embedded system, then you may not need any header files except the few
+that are part of GNU CC (and those of your program). However, if you
+intend to link your program with a standard C library such as `libc.a',
+then you probably need to compile with the header files that go with
+the library you use.
+
+ The GNU C compiler does not come with these files, because (1) they
+are system-specific, and (2) they belong in a C library, not in a
+compiler.
+
+ If the GNU C library supports your target machine, then you can get
+the header files from there (assuming you actually use the GNU library
+when you link your program).
+
+ If your target machine comes with a C compiler, it probably comes
+with suitable header files also. If you make these files accessible
+from the host machine, the cross-compiler can use them also.
+
+ Otherwise, you're on your own in finding header files to use when
+cross-compiling.
+
+ When you have found suitable header files, put them in
+`/usr/local/TARGET/include', before building the cross compiler. Then
+installation will run fixincludes properly and install the corrected
+versions of the header files where the compiler will use them.
+
+ Provide the header files before you build the cross-compiler, because
+the build stage actually runs the cross-compiler to produce parts of
+`libgcc.a'. (These are the parts that *can* be compiled with GNU CC.)
+Some of them need suitable header files.
+
+ Here's an example showing how to copy the header files from a target
+machine. On the target machine, do this:
+
+ (cd /usr/include; tar cf - .) > tarfile
+
+ Then, on the host machine, do this:
+
+ ftp TARGET-MACHINE
+ lcd /usr/local/TARGET/include
+ get tarfile
+ quit
+ tar xf tarfile
+
+Actually Building the Cross-Compiler
+------------------------------------
+
+ Now you can proceed just as for compiling a single-machine compiler
+through the step of building stage 1. If you have not provided some
+sort of `libgcc1.a', then compilation will give up at the point where
+it needs that file, printing a suitable error message. If you do
+provide `libgcc1.a', then building the compiler will automatically
+compile and link a test program called `libgcc1-test'; if you get
+errors in the linking, it means that not all of the necessary routines
+in `libgcc1.a' are available.
+
+ You must provide the header file `float.h'. One way to do this is
+to compile `enquire' and run it on your target machine. The job of
+`enquire' is to run on the target machine and figure out by experiment
+the nature of its floating point representation. `enquire' records its
+findings in the header file `float.h'. If you can't produce this file
+by running `enquire' on the target machine, then you will need to come
+up with a suitable `float.h' in some other way (or else, avoid using it
+in your programs).
+
+ Do not try to build stage 2 for a cross-compiler. It doesn't work to
+rebuild GNU CC as a cross-compiler using the cross-compiler, because
+that would produce a program that runs on the target machine, not on the
+host. For example, if you compile a 386-to-68030 cross-compiler with
+itself, the result will not be right either for the 386 (because it was
+compiled into 68030 code) or for the 68030 (because it was configured
+for a 386 as the host). If you want to compile GNU CC into 68030 code,
+whether you compile it on a 68030 or with a cross-compiler on a 386, you
+must specify a 68030 as the host when you configure it.
+
+ To install the cross-compiler, use `make install', as usual.
+
+Installing GNU CC on the Sun
+============================
+
+ On Solaris (version 2.1), do not use the linker or other tools in
+`/usr/ucb' to build GNU CC. Use `/usr/ccs/bin'.
+
+ Make sure the environment variable `FLOAT_OPTION' is not set when
+you compile `libgcc.a'. If this option were set to `f68881' when
+`libgcc.a' is compiled, the resulting code would demand to be linked
+with a special startup file and would not link properly without special
+pains.
+
+ There is a bug in `alloca' in certain versions of the Sun library.
+To avoid this bug, install the binaries of GNU CC that were compiled by
+GNU CC. They use `alloca' as a built-in function and never the one in
+the library.
+
+ Some versions of the Sun compiler crash when compiling GNU CC. The
+problem is a segmentation fault in cpp. This problem seems to be due to
+the bulk of data in the environment variables. You may be able to avoid
+it by using the following command to compile GNU CC with Sun CC:
+
+ make CC="TERMCAP=x OBJS=x LIBFUNCS=x STAGESTUFF=x cc"
+
+Installing GNU CC on VMS
+========================
+
+ The VMS version of GNU CC is distributed in a backup saveset
+containing both source code and precompiled binaries.
+
+ To install the `gcc' command so you can use the compiler easily, in
+the same manner as you use the VMS C compiler, you must install the VMS
+CLD file for GNU CC as follows:
+
+ 1. Define the VMS logical names `GNU_CC' and `GNU_CC_INCLUDE' to
+ point to the directories where the GNU CC executables
+ (`gcc-cpp.exe', `gcc-cc1.exe', etc.) and the C include files are
+ kept respectively. This should be done with the commands:
+
+ $ assign /system /translation=concealed -
+ disk:[gcc.] gnu_cc
+ $ assign /system /translation=concealed -
+ disk:[gcc.include.] gnu_cc_include
+
+ with the appropriate disk and directory names. These commands can
+ be placed in your system startup file so they will be executed
+ whenever the machine is rebooted. You may, if you choose, do this
+ via the `GCC_INSTALL.COM' script in the `[GCC]' directory.
+
+ 2. Install the `GCC' command with the command line:
+
+ $ set command /table=sys$common:[syslib]dcltables -
+ /output=sys$common:[syslib]dcltables gnu_cc:[000000]gcc
+ $ install replace sys$common:[syslib]dcltables
+
+ 3. To install the help file, do the following:
+
+ $ library/help sys$library:helplib.hlb gcc.hlp
+
+ Now you can invoke the compiler with a command like `gcc /verbose
+ file.c', which is equivalent to the command `gcc -v -c file.c' in
+ Unix.
+
+ If you wish to use GNU C++ you must first install GNU CC, and then
+perform the following steps:
+
+ 1. Define the VMS logical name `GNU_GXX_INCLUDE' to point to the
+ directory where the preprocessor will search for the C++ header
+ files. This can be done with the command:
+
+ $ assign /system /translation=concealed -
+ disk:[gcc.gxx_include.] gnu_gxx_include
+
+ with the appropriate disk and directory name. If you are going to
+ be using libg++, this is where the libg++ install procedure will
+ install the libg++ header files.
+
+ 2. Obtain the file `gcc-cc1plus.exe', and place this in the same
+ directory that `gcc-cc1.exe' is kept.
+
+ The GNU C++ compiler can be invoked with a command like `gcc /plus
+ /verbose file.cc', which is equivalent to the command `g++ -v -c
+ file.cc' in Unix.
+
+ We try to put corresponding binaries and sources on the VMS
+distribution tape. But sometimes the binaries will be from an older
+version than the sources, because we don't always have time to update
+them. (Use the `/version' option to determine the version number of
+the binaries and compare it with the source file `version.c' to tell
+whether this is so.) In this case, you should use the binaries you get
+to recompile the sources. If you must recompile, here is how:
+
+ 1. Execute the command procedure `vmsconfig.com' to set up the files
+ `tm.h', `config.h', `aux-output.c', and `md.', and to create files
+ `tconfig.h' and `hconfig.h'. This procedure also creates several
+ linker option files used by `make-cc1.com' and a data file used by
+ `make-l2.com'.
+
+ $ @vmsconfig.com
+
+ 2. Setup the logical names and command tables as defined above. In
+ addition, define the VMS logical name `GNU_BISON' to point at the
+ to the directories where the Bison executable is kept. This
+ should be done with the command:
+
+ $ assign /system /translation=concealed -
+ disk:[bison.] gnu_bison
+
+ You may, if you choose, use the `INSTALL_BISON.COM' script in the
+ `[BISON]' directory.
+
+ 3. Install the `BISON' command with the command line:
+
+ $ set command /table=sys$common:[syslib]dcltables -
+ /output=sys$common:[syslib]dcltables -
+ gnu_bison:[000000]bison
+ $ install replace sys$common:[syslib]dcltables
+
+ 4. Type `@make-gcc' to recompile everything (alternatively, submit
+ the file `make-gcc.com' to a batch queue). If you wish to build
+ the GNU C++ compiler as well as the GNU CC compiler, you must
+ first edit `make-gcc.com' and follow the instructions that appear
+ in the comments.
+
+ 5. In order to use GCC, you need a library of functions which GCC
+ compiled code will call to perform certain tasks, and these
+ functions are defined in the file `libgcc2.c'. To compile this
+ you should use the command procedure `make-l2.com', which will
+ generate the library `libgcc2.olb'. `libgcc2.olb' should be built
+ using the compiler built from the same distribution that
+ `libgcc2.c' came from, and `make-gcc.com' will automatically do
+ all of this for you.
+
+ To install the library, use the following commands:
+
+ $ library gnu_cc:[000000]gcclib/delete=(new,eprintf)
+ $ library gnu_cc:[000000]gcclib/delete=L_*
+ $ library libgcc2/extract=*/output=libgcc2.obj
+ $ library gnu_cc:[000000]gcclib libgcc2.obj
+
+ The first command simply removes old modules that will be replaced
+ with modules from `libgcc2' under different module names. The
+ modules `new' and `eprintf' may not actually be present in your
+ `gcclib.olb'--if the VMS librarian complains about those modules
+ not being present, simply ignore the message and continue on with
+ the next command. The second command removes the modules that
+ came from the previous version of the library `libgcc2.c'.
+
+ Whenever you update the compiler on your system, you should also
+ update the library with the above procedure.
+
+ 6. You may wish to build GCC in such a way that no files are written
+ to the directory where the source files reside. An example would
+ be the when the source files are on a read-only disk. In these
+ cases, execute the following DCL commands (substituting your
+ actual path names):
+
+ $ assign dua0:[gcc.build_dir.]/translation=concealed, -
+ dua1:[gcc.source_dir.]/translation=concealed gcc_build
+ $ set default gcc_build:[000000]
+
+ where the directory `dua1:[gcc.source_dir]' contains the source
+ code, and the directory `dua0:[gcc.build_dir]' is meant to contain
+ all of the generated object files and executables. Once you have
+ done this, you can proceed building GCC as described above. (Keep
+ in mind that `gcc_build' is a rooted logical name, and thus the
+ device names in each element of the search list must be an actual
+ physical device name rather than another rooted logical name).
+
+ 7. *If you are building GNU CC with a previous version of GNU CC, you
+ also should check to see that you have the newest version of the
+ assembler*. In particular, GNU CC version 2 treats global constant
+ variables slightly differently from GNU CC version 1, and GAS
+ version 1.38.1 does not have the patches required to work with GCC
+ version 2. If you use GAS 1.38.1, then `extern const' variables
+ will not have the read-only bit set, and the linker will generate
+ warning messages about mismatched psect attributes for these
+ variables. These warning messages are merely a nuisance, and can
+ safely be ignored.
+
+ If you are compiling with a version of GNU CC older than 1.33,
+ specify `/DEFINE=("inline=")' as an option in all the
+ compilations. This requires editing all the `gcc' commands in
+ `make-cc1.com'. (The older versions had problems supporting
+ `inline'.) Once you have a working 1.33 or newer GNU CC, you can
+ change this file back.
+
+ 8. If you want to build GNU CC with the VAX C compiler, you will need
+ to make minor changes in `make-cccp.com' and `make-cc1.com' to
+ choose alternate definitions of `CC', `CFLAGS', and `LIBS'. See
+ comments in those files. However, you must also have a working
+ version of the GNU assembler (GNU as, aka GAS) as it is used as
+ the back-end for GNU CC to produce binary object modules and is
+ not included in the GNU CC sources. GAS is also needed to compile
+ `libgcc2' in order to build `gcclib' (see above); `make-l2.com'
+ expects to be able to find it operational in
+ `gnu_cc:[000000]gnu-as.exe'.
+
+ To use GNU CC on VMS, you need the VMS driver programs `gcc.exe',
+ `gcc.com', and `gcc.cld'. They are distributed with the VMS
+ binaries (`gcc-vms') rather than the GNU CC sources. GAS is also
+ included in `gcc-vms', as is Bison.
+
+ Once you have successfully built GNU CC with VAX C, you should use
+ the resulting compiler to rebuild itself. Before doing this, be
+ sure to restore the `CC', `CFLAGS', and `LIBS' definitions in
+ `make-cccp.com' and `make-cc1.com'. The second generation
+ compiler will be able to take advantage of many optimizations that
+ must be suppressed when building with other compilers.
+
+ Under previous versions of GNU CC, the generated code would
+occasionally give strange results when linked with the sharable
+`VAXCRTL' library. Now this should work.
+
+ Even with this version, however, GNU CC itself should not be linked
+with the sharable `VAXCRTL'. The version of `qsort' in `VAXCRTL' has a
+bug (known to be present in VMS versions V4.6 through V5.5) which
+causes the compiler to fail.
+
+ The executables are generated by `make-cc1.com' and `make-cccp.com'
+use the object library version of `VAXCRTL' in order to make use of the
+`qsort' routine in `gcclib.olb'. If you wish to link the compiler
+executables with the shareable image version of `VAXCRTL', you should
+edit the file `tm.h' (created by `vmsconfig.com') to define the macro
+`QSORT_WORKAROUND'.
+
+ `QSORT_WORKAROUND' is always defined when GNU CC is compiled with
+VAX C, to avoid a problem in case `gcclib.olb' is not yet available.
+
+`collect2'
+==========
+
+ Many target systems do not have support in the assembler and linker
+for "constructors"--initialization functions to be called before the
+official "start" of `main'. On such systems, GNU CC uses a utility
+called `collect2' to arrange to call these functions at start time.
+
+ The program `collect2' works by linking the program once and looking
+through the linker output file for symbols with particular names
+indicating they are constructor functions. If it finds any, it creates
+a new temporary `.c' file containing a table of them, compiles it, and
+links the program a second time including that file.
+
+ The actual calls to the constructors are carried out by a subroutine
+called `__main', which is called (automatically) at the beginning of
+the body of `main' (provided `main' was compiled with GNU CC). Calling
+`__main' is necessary, even when compiling C code, to allow linking C
+and C++ object code together. (If you use `-nostdlib', you get an
+unresolved reference to `__main', since it's defined in the standard
+GCC library. Include `-lgcc' at the end of your compiler command line
+to resolve this reference.)
+
+ The program `collect2' is installed as `ld' in the directory where
+the passes of the compiler are installed. When `collect2' needs to
+find the *real* `ld', it tries the following file names:
+
+ * `real-ld' in the directories listed in the compiler's search
+ directories.
+
+ * `real-ld' in the directories listed in the environment variable
+ `PATH'.
+
+ * The file specified in the `REAL_LD_FILE_NAME' configuration macro,
+ if specified.
+
+ * `ld' in the compiler's search directories, except that `collect2'
+ will not execute itself recursively.
+
+ * `ld' in `PATH'.
+
+ "The compiler's search directories" means all the directories where
+`gcc' searches for passes of the compiler. This includes directories
+that you specify with `-B'.
+
+ Cross-compilers search a little differently:
+
+ * `real-ld' in the compiler's search directories.
+
+ * `TARGET-real-ld' in `PATH'.
+
+ * The file specified in the `REAL_LD_FILE_NAME' configuration macro,
+ if specified.
+
+ * `ld' in the compiler's search directories.
+
+ * `TARGET-ld' in `PATH'.
+
+ `collect2' explicitly avoids running `ld' using the file name under
+which `collect2' itself was invoked. In fact, it remembers up a list
+of such names--in case one copy of `collect2' finds another copy (or
+version) of `collect2' installed as `ld' in a second place in the
+search path.
+
+ `collect2' searches for the utilities `nm' and `strip' using the
+same algorithm as above for `ld'.
+
+Standard Header File Directories
+================================
+
+ `GCC_INCLUDE_DIR' means the same thing for native and cross. It is
+where GNU CC stores its private include files, and also where GNU CC
+stores the fixed include files. A cross compiled GNU CC runs
+`fixincludes' on the header files in `$(tooldir)/include'. (If the
+cross compilation header files need to be fixed, they must be installed
+before GNU CC is built. If the cross compilation header files are
+already suitable for ANSI C and GNU CC, nothing special need be done).
+
+ `GPLUS_INCLUDE_DIR' means the same thing for native and cross. It
+is where `g++' looks first for header files. `libg++' installs only
+target independent header files in that directory.
+
+ `LOCAL_INCLUDE_DIR' is used only for a native compiler. It is
+normally `/usr/local/include'. GNU CC searches this directory so that
+users can install header files in `/usr/local/include'.
+
+ `CROSS_INCLUDE_DIR' is used only for a cross compiler. GNU CC
+doesn't install anything there.
+
+ `TOOL_INCLUDE_DIR' is used for both native and cross compilers. It
+is the place for other packages to install header files that GNU CC will
+use. For a cross-compiler, this is the equivalent of `/usr/include'.
+When you build a cross-compiler, `fixincludes' processes any header
+files in this directory.

+Free Software Redistributors Donate
+***********************************
+
+In adddition to their conference donation, Red Hat Software has agreed to
+donate $1.00 to the FSF for every copy of Red Hat Archives sold. They have
+also added a GNU logo to the back of that CD with the words "Supports the
+Free Software Foundation".
+
+The SNOW 2.1 CD producers added the words "Includes $5 donation to the FSF"
+to the front of their CD. Potential buyers will know just how much of the
+price is for the FSF & how much is for the redistributor.
+
+The Sun Users Group Deutschland has made it even clearer: their CD says,
+"Price 90 DM, + 12 DM donation to the FSF." We thank them for their
+contribution to our efforts.
+
+Kyoto Micro Computer of Japan regularly gives us 10% of their GNU-related
+sales.
+
+Mr. Hiroshi, Mr. Kojima, and the other authors of the `Linux Primer' in Japan
+have donated money from the sales of their book.
+
+Infomagic has continued to make sizeable donations to the FSF.
+
+At the request of author Arnold Robbins, Specialized Systems Consultants, Inc.
+continues to donate 3% of their profits from selling `Effective AWK
+Programming'. We would also like to acknowledge the many SSC authors who
+have donated their royalties and fees to the FSF.
+
+In the long run, the success of free software depends on how much new free
+software people develop. Free software distribution offers an opportunity to
+raise funds for such development in an ethical way. These redistributors
+have made use of the opportunity. Many others let it go to waste.
+
+You can help promote free software development by convincing for-a-fee
+redistributors to contribute--either by doing development themselves or by
+donating to development organizations (the FSF and others).
+
+The way to convince distributors to contribute is to demand and expect this
+of them. This means choosing among distributors partly by how much they give
+to free software development. Then you can show distributors they must
+compete to be the one who gives the most.
+
+To make this work, you must insist on numbers that you can compare, such as,
+"We will give ten dollars to the Foobar project for each disk sold." A vague
+commitment, such as "A portion of the profits is donated," doesn't give you a
+basis for comparison. Even a precise fraction "of the profits from this
+disk" is not very meaningful, since creative accounting and unrelated
+business decisions can greatly alter what fraction of the sales price counts
+as profit.
+
+Also, press developers for firm information about what kind of development
+they do or support. Some kinds make much more long-term difference than
+others. For example, maintaining a separate version of a GNU program
+contributes very little; maintaining a program on behalf of the GNU Project
+<contributes much. Easy new ports contribute little, since someone else
+would surely do them; difficult ports such as adding a new CPU to the GNU
+compiler or Mach contribute more; major new features & programs contribute
+the most.
+
+By establishing the idea that supporting further development is "the proper
+thing to do" when distributing free software for a fee, we can assure a
+steady flow of resources for making more free software.
+
+
+
+Help from Free Software Companies
+*********************************
+
+When choosing a free software business, ask those you are considering how
+much they do to assist free software development, e.g., by contributing money
+to free software development or by writing free software improvements
+themselves for general use. By basing your decision partially on this
+factor, you can help encourage those who profit from free software to
+contribute to its growth.
+
+Wingnut (SRA's special GNU support group) regularly donates a part of its
+income to the FSF to support the development of new GNU programs. Listing

+
+Major Changes in GNU Software and Documentation
+***********************************************
+
+ * Hurd Progress (Also *note What Is the Hurd::.)
+
+ We have made two test releases of the Hurd, and we will make another
+ (version 0.2) in this month. Stability is improving, and we have begun
+ modifying various user-level utilities to understand new Hurd filesystem
+ features (fileutils, shellutils, tar, etc.).
+
+ One way for people to help out is to compile and run as much third-party
+ free software as they can; in this way we can find bugs and deficiencies
+ with some rapidity. Volunteers with a PC are therefore eagerly sought
+ to get the new 0.2 release and compile their favorite Unix programs and
+ games.
+
+ * GNU System Progress
+
+ Version 0.2 of the GNU system will be released in this month, to coincide
+ with the 0.2 release of the Hurd. This complete GNU system is available
+ by FTP. We are working with Ian Murdock to develop an excellent package
+ management system for GNU. This will make administering and upgrading
+ the system much easier. Because of features only the Hurd has, the GNU
+ package management system will be simpler and more featureful than
+ similar package systems for various GNU/Linux distributions.
+
+ * New Source Code CD! (See *Note January 1997 Source Code CD-ROMs::)
+
+ We are releasing the January 1997 (Edition 9) Source Code CD-ROM this
+ month. Once again, it is a two disk set. It includes several new
+ programs: `gforth', `gpc', <Meta-HTML>, `stow', `units', VRweb, `wget',
+ `windows32api', and `xinfo'. On the CD-ROMs are full distributions of
+ X11R6.3, MIT Scheme, Emacs, GCC, and current versions of all other GNU
+ Software. *Note GNU Software::, for more about these packages.
+
+ * New Compiler Tools CD-ROM
+
+ We are releasing the January 1997 (Edition 4) Compiler Tools Binaries
+ CD. Support is included for several new operating systems.
+
+ The Compiler Tools Binaries CD-ROM contains executables of the GNU
+ compiler tools for some systems that don't normally come with a
+ compiler. This allows users of those systems to compile their own
+ software without having to buy a proprietary compiler.
+
+ We hope to include more systems with each update of this CD-ROM. If you
+ can help build binaries for new systems or have one to suggest, please
+ contact us at either address on the top menu. For more information, see
+ *Note Compiler Tools Binaries CD-ROM::.
+
+ * New/Updated Manuals since Last Bulletin (See *Note Documentation::)
+
+ Since the last bulletin, we have published new editions of: `Debugging
+ with GDB', for version 4.16 with a new color cover; `Texinfo' Manual,
+ edition 2.24; & the `GNU Emacs Manual', for version 19.33 with a new
+ color cover. `Using and Porting GNU CC' has been re-printed in a
+ lay-flat bound edition with a new color cover. A new Bison Manual with
+ a new color cover is planned.
+
+ * Give to GNU the United Way!
+
+ As a 501(c)3 tax-exempt organization, the FSF is eligible to receive
+ United Way funds. When donating to United Way, one can specify that all
+ or part of the donation be directed to the FSF. On the donor form,
+ check the "Specific Requests" box and include the sentence, "Send my
+ gift to the Free Software Foundation, 59 Temple Place, Suite 330,
+ Boston, MA 02111." We especially appreciate the donations from Microsoft
+ matching the United Way donations of their employees. Also see *Note
+ Donations Translate Into Free Software:: and *Note Cygnus Matches
+ Donations!::.
+
+ * GNU Software Works on MS-DOS (Also *note GNU Software::.)
+
+ GNU Emacs 19 and many other GNU programs have been ported to MS-DOS for
+ i386/i486/Pentium machines. We ship binaries & sources on the *Note
+ Compiler Tools Binaries CD-ROM::.
+
+ * MULE Merge Almost Complete
+
+ MULE is the Multi-Lingual Emacs developed by Ken'ichi Handa at the
+ Electro-Technical Lab in Tsukuba, Japan. Handa has readied the code for
+ merging into Emacs and we expect to complete the merge soon.
+
+ * GCC (For current status on GCC and GNAT, *note GNU Software::.)
+
+ New front ends for GCC are being done for Pascal & Chill. Pascal,
+ `gpc', stagnated for some years, but should be released by the time you
+ read this. See `http://agnes.dida.physik.uni-essen.de/~gnu-pascal'.
+
+ * GUILE
+
+ GUILE is currently available as a test release. GNU's Ubiquitous
+ Intelligent Language for Extension is an SCM-based library that can make
+ any ordinary C program extensible. (For SCM info, see "JACAL" in *Note
+ GNU Software::.)
+
+ Also being developed are SCSH-compatible system call & Tk interfaces, a
+ module system, dynamic linking support, & a byte-code interpreter.
+ Support for Emacs Lisp & a more C-like language is coming.
+
+ * Texinfo (For current status, *note GNU Software::.)
+
+ Texinfo now provides macro facilities and supports multicolumn tables.
+ It comes with an `install-info' program that packages can use to update
+ the `dir' file automatically when they install their Info files.
+
+ * GNU Common Lisp (For current status, *note GNU Software::.)
+
+ Version 2.2.1 of GNU Common Lisp (GCL) was released in December '96. It
+ now includes a graphical interface to the Tk widget system. All
+ documentation is now Texinfo-based, with built-in regexp matching used
+ to access the documentation. A first pass at the Common Lisp condition
+ system is also included. Version 2.2.1 contains mainly updates to allow
+ GCL 2.2 to work correctly with current operating system levels, and to
+ fix bugs. Volunteers to help with the move to the ANSI standard are
+ most welcome; please contact `schelter@math.utexas.edu'.
+
+ * Experimental Electronic Cash
+
+ `http://www.lysator.liu.se/~nisse/NCash' is an experimental
+ implementation of anonymous electronic cash which is to be released as
+ free software.
+
+ * HTML Professional and GPL
+
+ The recent development and release of HTML Professional was made under
+ the terms of the GNU GPL. In order to facilitate distribution, the GPL
+ text was re-encoded into this more recent version of HTML, and is now
+ distributed with HTML Pro. An online copy can be retrieved at
+ `http://www.arbornet.org/~silmaril/dtds/html/gnugpl.html'.
+
+ HTML Pro is an unofficial version of the HTML DTD. HTML Pro is
+ distributed for discussion by the `www-html' mailing list. It
+ composites all other known versions, and allows World Wide Web designers
+ to use recent experimental additions in a rational and structured manner.
+ It comes with a `.ced' file for GNU Emacs/psgml-mode and can be gotten at
+ `ftp://www.ucc.ie/pub/html/htmlpro.{zip|tar.gz|zip.hqx}'.
+ Documentation is at
+ `http://www.arbornet.org/~silmaril/dtds/html/htmlpro.html'.
+
+ * Meta-HTML 5.01 Source Release
+
+ Version 5.01 of Universal Access Inc.'s <Meta-HTML> is now available.
+
+ <Meta-HTML> is a programming language specifically designed to work
+ within the environment of the World Wide Web. Although it is a genuine
+ programming language, suitable for large-scale symbolic manipulation,
+ <Meta-HTML> also provides the most commonly wanted Web functionality as
+ built-in primitives, so you don't have to write them. You can find out
+ more about the theory of implementation in this white paper
+ `http://www.metahtml.com/meta-html/manifesto.html'.
+
+ Web pages are authored using HTML and <Meta-HTML> statements freely
+ intermixed. When a page is requested by a browser, the page is passed
+ through the <Meta-HTML> engine, which dynamically processes any
+ <Meta-HTML> statements to produce a final HTML page which is delivered
+ to the browser.
+
+ The source distribution provides several different interpreter options:
+ a CGI engine which can be run by any Unix Web server; a full-featured
+ Web server (mhttpd) with the interpreter built in; a standalone
+ processor, much like Perl or Tcl; and an interactive debugger, with a
+ feel similar to GDB (mdb).
+
+ There is a user mailing list: `metahtml-users@metahtml.com'. You can
+ subscribe on the Web at `http://www.metahtml.com/E-Mail/', or by sending
+ mail to `metahtml-users-request@metahtml.com'.
+
+ Pre-compiled distribution sets for some systems are available via the
+ <Meta-HTML> Web site at `http://www.metahtml.com'.
+
+ * VRweb Browser
+
+ VRweb, a browser for 3D models on the Web written in the Virtual Reality
+ Modeling Language (VRML), is now available under the GPL. VRweb works
+ in conjunction with Web browsers on Unix & Windows platforms.
+
+ VRweb is a joint project of IICM (home of Hyper-G), NCSA (home of
+ Mosaic), & the University of Minnesota (home of Gopher). The software
+ is freely available in binary & source. VRweb 1.2 for Unix has just
+ been released, VRweb 1.2 for Windows will follow in due course. You can
+ download VRweb from `ftp://iicm.tu-graz.ac.at/pub/Hyper-G/VRweb/UNIX'
+ and numerous mirror sites. Further information on VRweb can be found at
+ `http://hyperg.iicm.tu-graz.ac.at/vrweb'.
+
+ VRML is a non-proprietary, platform-independent file format for 3D
+ graphics on the Internet. Also see `http://www.sdsc.edu/vrml/', the
+ VRML Repository.
+
+
+
+The Deluxe Distribution
+***********************
+
+The Free Software Foundation has been asked repeatedly to create a package
+that provides executables for all of our software. Normally we offer only
+sources. The Deluxe Distribution provides binaries with the source code and
+includes six T-shirts, all our CD-ROMs, printed manuals, & reference cards.
+
+The FSF Deluxe Distribution contains the binaries and sources to hundreds of
+different programs including Emacs, the GNU C/C++ Compiler, the GNU Debugger,
+the complete X Window System, and all the GNU utilities.
+
+We will make a Deluxe Distribution for most machines/operating systems. We
+may be able to send someone to your office to do the compilation, if we can't
+find a suitable machine here. However, we can only compile the programs that
+already support your chosen machine/system - porting is a separate matter.
+(To commission a port, see the GNU Service Directory; details in *Note Free
+Software Support::.) Compiling all these programs takes time; a Deluxe
+Distribution for an unusual machine will take longer to produce than one for
+a common machine. Please contact the FSF Office with any questions.
+
+We supply the software on a write-once CD-ROM (in ISO 9660 format with "Rock
+Ridge" extensions), or on one of these tapes in Unix `tar' format: 1600 or
+6250bpi 1/2in reel, Sun DC300XLP 1/4in cartridge - QIC24, IBM RS/6000 1/4in
+c.t. - QIC 150, Exabyte 8mm c.t., or DAT 4mm c.t. If your computer cannot
+read any of these, please contact us to see if we can handle your format.
+
+The manuals included are one each of `Bison', `Calc', `GAWK', `GCC', `GNU C
+Library', `GDB', `Flex', `GNU Emacs Lisp Reference', `Programming in Emacs
+Lisp: An Introduction', `Make', `Texinfo', & `Termcap' manuals; six copies of
+the `GNU Emacs' manual; and ten reference cards each for Emacs, Bison, Calc,
+Flex, & GDB.
+
+Every Deluxe Distribution also has a copy of the latest editions of our
+CD-ROMs that have sources of our software & compiler tool binaries for some
+systems. The CDs are in ISO 9660 format with Rock Ridge extensions.
+
+The price of the Deluxe Distribution is $5000 (shipping included). These
+sales provide enormous financial assistance to help the FSF develop more free
+software. To order, please fill out the "Deluxe Distribution" section on the
+*note Free Software Foundation Order Form::. and send it to:

+GNU Documentation
+*****************
+
+GNU is dedicated to having quality, easy-to-use online & printed
+documentation. GNU manuals are intended to explain underlying concepts,
+describe how to use all the features of each program, & give examples of
+command use. GNU manuals are distributed as Texinfo source files, which
+yield both typeset hardcopy via the TeX document formatting system and online
+hypertext display via the menu-driven Info system. Source for these manuals
+comes with our software; here are the manuals that we publish as printed
+books. See the *note Free Software Foundation Order Form::., to order them.
+
+Most GNU manuals are bound as soft cover books with "lay-flat" bindings.
+This allows you to open them so they lie flat on a table without creasing the
+binding. They have an inner cloth spine and an outer cardboard cover that
+will not break or crease as an ordinary paperback will. Currently, the
+`Using and Porting GNU CC', `GDB', `Emacs', `Emacs Lisp Reference',
+`Programming in Emacs Lisp: An Introduction', `GNU Awk User's Guide', `Make',
+& `Bison' manuals have this binding. Our other manuals also lie flat when
+opened, using a GBC binding. Our manuals are 7in by 9.25in except the 8.5in
+by 11in `Calc' manual.
+
+The edition number of the manual and version number of the program listed
+after each manual's name were current at the time this Bulletin was published.
+
+`Debugging with GDB' (for Version 4.16) tells how to run your program under
+GNU Debugger control, examine and alter data, modify a program's flow of
+control, and use GDB through GNU Emacs.
+
+The `GNU Emacs Manual' (12th Edition for Version 19.33) describes editing with
+GNU Emacs. It explains advanced features, including outline mode and regular
+expression search; how to use special programming modes to write languages
+like C++ and TeX; how to use the `tags' utility; how to compile and correct
+code; how to make your own keybindings; and other elementary customizations.
+
+`Programming in Emacs Lisp: An Introduction' (October 1995 Edition 1.04) is
+for people who are not necessarily interested in programming, but who do want
+to customize or extend their computing environment. If you read it in Emacs
+under Info mode, you can run the sample programs directly.
+
+`The GNU Emacs Lisp Reference Manual' (Edition 2.4 for Version 19.29) and
+`The GNU Emacs Lisp Reference, Japanese Edition' (Japanese Draft Revision
+1.0, from English Edition 2.4 for Version 19.29) cover this programming
+language in depth, including data types, control structures, functions,
+macros, syntax tables, searching/matching, modes, windows, keymaps, byte
+compilation, and the operating system interface.
+
+`The GNU Awk User's Guide' (Edition 1.0 for Version 3.0) tells how to use
+`gawk'. It is written for those who have never used `awk' and describes
+features of this powerful string and record manipulation language. It
+clearly delineates those features which are part of POSIX `awk' from `gawk'
+extensions, providing a comprehensive guide to `awk' program portability.
+
+`GNU Make' (Edition 0.50 for Version 3.75 Beta) describes GNU `make', a
+program used to rebuild parts of other programs. The manual tells how to
+write "makefiles", which specify how a program is to be compiled and how its
+files depend on each other. Included are an introductory chapter for novice
+users and a section about automatically generated dependencies.
+
+The `Flex' manual (Edition 1.03 for Version 2.3.7) teaches you to write a
+lexical scanner definition for the `flex' program to create a C++ or C-coded
+scanner that recognizes the patterns defined. You need no prior knowledge of
+scanners.
+
+`The Bison Manual' (November 1995 Edition for Version 1.25) teaches you how
+to write context-free grammars for the Bison program that convert into
+C-coded parsers. You need no prior knowledge of parser generators.
+
+`Using and Porting GNU CC' (November 1995 Edition for Version 2.7.2) tells
+how to run, install, and port the GNU C Compiler to new systems. It lists
+new features and incompatibilities of GCC, but people not familiar with C
+will still need a good reference on the C programming language. It also
+covers G++.
+
+The `Texinfo' manual (Edition 2.24 for Version 3) explains the markup
+language that produces our online Info documentation & typeset hardcopies.
+It tells you how to make tables, lists, chapters, nodes, accented & special
+characters, indexes, cross references, & how to catch mistakes.
+
+`The Termcap Manual' (3rd Edition for Version 1.3), often described as "twice
+as much as you ever wanted to know about termcap," details the format of the
+termcap database, the definitions of terminal capabilities, and the process
+of interrogating a terminal description. This manual is primarily for
+programmers.
+
+The `C Library Reference Manual' (Edition 0.08 for Version 2.0) describes the
+library's facilities, including both what Unix calls "library functions" &
+"system calls." We are doing small copier runs of this manual until it
+becomes more stable. Please send fixes to `bug-glibc-manual@prep.ai.mit.edu'.
+
+The `Emacs Calc Manual' (for Version 2.02) is both a tutorial and a reference
+manual. It tells how to do ordinary arithmetic, how to use Calc for algebra,
+calculus, and other forms of mathematics, and how to extend Calc.

+
+GNU Software
+************
+
+All our software is available via FTP; see *Note How to Get GNU Software::.
+We also offer *Note CD-ROMs::, and printed *Note Documentation::, which
+includes manuals and reference cards. In the articles describing the
+contents of each medium, the version number listed after each program name
+was current when we published this Bulletin. When you order a newer CD-ROM,
+some of the programs may be newer and therefore the version number higher.
+See the *note Free Software Foundation Order Form::., for ordering
+information.
+
+Some of the contents of our FTP distributions are compressed. We have
+software on our FTP sites to uncompress these files. Due to patent troubles
+with `compress', we use another compression program, `gzip'. (Such
+prohibitions on software development are fought by the League for Programming
+Freedom; *note What Is the LPF::., for details.)
+
+You may need to build GNU `make' before you build our other software. Some
+vendors supply no `make' utility at all and some native `make' programs lack
+the `VPATH' feature essential for using the GNU configure system to its full
+extent. The GNU `make' sources have a shell script to build `make' itself on
+such systems.
+
+We welcome all bug reports and enhancements sent to the appropriate
+electronic mailing list (*note Free Software Support::.).
+
+
+
+Configuring GNU Software
+------------------------
+
+We are using Autoconf, a uniform scheme for configuring GNU software packages
+in order to compile them (see "Autoconf" and "Automake" below, in this
+article). The goal is to have all GNU software support the same alternatives
+for naming machine and system types.
+
+Ultimately, it will be possible to configure and build the entire system all
+at once, eliminating the need to configure each individual package separately.
+
+You can also specify both the host and target system to build
+cross-compilation tools. Most GNU programs now use Autoconf-generated
+configure scripts.
+
+
+
+GNU Software Now Available
+--------------------------
+
+For future programs and features, see *Note Forthcoming GNUs::.
+
+Key to cross reference:
+
+ BinCD January 1997 Binaries CD-ROM
+ SrcCD January 1997 Source CD-ROMs
+
+[FSFman] shows that we sell a manual for that package. [FSFrc] shows we sell
+a reference card for that package. To order them, see the *note Free
+Software Foundation Order Form::. *Note Documentation::, for more
+information on the manuals. Source code for each manual or reference card is
+included with each package.
+
+ * `acm' (SrcCD)
+
+ `acm' is a LAN-oriented, multiplayer, aerial combat simulation that runs
+ under the X Window System. Players engage in air to air combat against
+ one another using heat seeking missiles and cannons. We are working on
+ a more accurate simulation of real airplane flight characteristics.
+
+ * Apache *Also see* `http://www.apache.org/' (SrcCD)
+
+ Apache is an HTTP server designed as a successor to the NCSA family of
+ web servers. It adds a significant amount of new functionality, has an
+ extensive API for modular enhancements, is extremely flexible without
+ compromising speed, and has an active development group and user
+ community.
+
+ * Autoconf (SrcCD)
+
+ Autoconf produces shell scripts which automatically configure source code
+ packages. These scripts adapt the packages to many kinds of Unix-like
+ systems without manual user intervention. Autoconf creates a script for
+ a package from a template file which lists the operating system features
+ which the package can use, in the form of `m4' macro calls. Autoconf
+ requires GNU `m4' to operate, but the resulting configure scripts it
+ generates do not.
+
+ * Automake (SrcCD)
+
+ Automake is a tool for generating `Makefile.in's for use with Autoconf.
+ The generated makefiles are compliant with GNU Makefile standards.
+
+ * BASH (SrcCD)
+
+ GNU's shell, BASH (Bourne Again SHell), is compatible with the Unix `sh'
+ and offers many extensions found in `csh' and `ksh'. BASH has job
+ control, `csh'-style command history, command-line editing (with Emacs
+ and `vi' modes built-in), and the ability to rebind keys via the
+ `readline' library. BASH conforms to the POSIX 1003.2-1992 standard.
+
+ * `bc' (SrcCD)
+
+ `bc' is an interactive algebraic language with arbitrary precision
+ numbers. GNU `bc' follows the POSIX 1003.2-1992 standard with several
+ extensions, including multi-character variable names, an `else'
+ statement, and full Boolean expressions. The RPN calculator `dc' is now
+ distributed as part of the same package, but GNU `bc' is not implemented
+ as a `dc' preprocessor.
+
+ * BFD (BinCD, SrcCD)
+
+ The Binary File Descriptor library allows a program which operates on
+ object files (e.g., `ld' or GDB) to support many different formats in a
+ clean way. BFD provides a portable interface, so that only BFD needs to
+ know the details of a particular format. One result is that all
+ programs using BFD will support formats such as a.out, COFF, and ELF.
+ BFD comes with Texinfo source for a manual (not yet published on paper).
+
+ At present, BFD is not distributed separately; it is included with
+ packages that use it.
+
+ * Binutils (BinCD, SrcCD)
+
+ Binutils includes these programs: `ar', `c++filt', `demangle', `gas',
+ `gprof', `ld', `nlmconv', `nm', `objcopy', `objdump', `ranlib', `size',
+ `strings', & `strip'.
+
+ Binutils version 2 uses the BFD library. The GNU assembler, `gas',
+ supports the a29k, Alpha, H8/300, H8/500, HP-PA, i386, i960, m68k, m88k,
+ MIPS, NS32K, SH, SPARC, Tahoe, Vax, and Z8000 CPUs, and attempts to be
+ compatible with many other assemblers for Unix and embedded systems. It
+ can produce mixed C and assembly listings, and includes a macro facility
+ similar to that in some other assemblers. GNU's linker, `ld', emits
+ source-line numbered error messages for multiply-defined symbols and
+ undefined references, and interprets a superset of AT&T's Linker Command
+ Language, which gives control over where segments are placed in memory.
+ `nlmconv' converts object files into Novell NetWare Loadable Modules.
+ `objdump' can disassemble code for most of the CPUs listed above, and
+ can display other data (e.g., symbols and relocations) from any file
+ format read by BFD.
+
+ * Bison *See *Note Documentation::* (BinCD, SrcCD) [FSFman, FSFrc]
+
+ Bison is an upwardly compatible replacement for the parser generator
+ `yacc'. Texinfo source for the `Bison Manual' and reference card are
+ included.
+
+ * C Library *See *Note Forthcoming GNUs::* (BinCD, SrcCD) [FSFman]
+
+ The GNU C library supports ISO C-1989, ISO C/amendment 1-1995, POSIX
+ 1003.1-1990, POSIX 1003.1b-1993, POSIX 1003.1c-1995 (when the underlying
+ system permits), & most of the functions in POSIX 1003.2-1992. It is
+ nearly compliant with the extended XPG4.2 specification which guarantees
+ upward compatibility with 4.4BSD & many System V functions.
+
+ When used with the GNU Hurd, the C Library performs many functions of the
+ Unix system calls directly. Mike Haertel has written a fast `malloc'
+ which wastes less memory than the old GNU version.
+
+ GNU `stdio' lets you define new kinds of streams, just by writing a few
+ C functions. Two methods for handling translated messages help writing
+ internationalized programs & the user can adopt the environment the
+ program runs in to conform with local conventions. Extended `getopt'
+ functions are already used to parse options, including long options, in
+ many GNU utilities. The name lookup functions now are modularized which
+ makes it easier to select the service which is needed for the specific
+ database & the document interface makes it easy to add new services.
+ Texinfo source for the `GNU C Library Reference Manual' is included
+ (*note Documentation::.).
+
+ Previous versions of the GNU C library ran on a large number of systems.
+ The architecture-dependent parts of the C library have not been updated
+ since development on version 2.0 started, so today it runs out of the
+ box only on GNU/Hurd (all platforms GNU/Hurd also runs on) & GNU/Linux
+ (ix86, Alpha, m68k, work is in progress for MIPS & Sparc). Other
+ architectures will become available again as soon as somebody does the
+ port.
+
+ * C++ Library (BinCD, SrcCD)
+
+ The GNU C++ library (libg++) contains an extensive collection of
+ container and utility classes, including Obstacks, multiple-precision
+ Integers and Rationals, Complex numbers, BitSets, and BitStrings.
+
+ The distribution also includes the libstdc++ library. This implements
+ library facilities defined by the forthcoming ANSI/ISO C++ standard,
+ including strings, the iostream library, and a port of the Standard
+ Template Library.
+
+ * Calc (SrcCD) [FSFman, FSFrc]
+
+ Calc (written by Dave Gillespie in Emacs Lisp) is an extensible, advanced
+ desk calculator & mathematical tool that runs as part of GNU Emacs. You
+ can use Calc as a simple four-function calculator, but it has many more
+ features including: choice of algebraic or RPN (stack-based) entry;
+ logarithmic, trigonometric, & financial functions; arbitrary precision;
+ complex numbers; vectors; matrices; dates; times; infinities; sets;
+ algebraic simplification; & differentiation & integration. It outputs to
+ `gnuplot', & comes with source for a manual & reference card (*note
+ Documentation::.).
+
+ * `cfengine' (SrcCD)
+
+ `cfengine' is used to maintain site-wide configuration of a
+ heterogeneous Unix network using a simple high level language. Its
+ appearance is similar to `rdist', but allows many more operations to be
+ performed automatically. See Mark Burgess, "A Site Configuration
+ Engine", `Computing Systems', Vol. 8, No. 3 (ask `office@usenix.org' how
+ to get a copy).
+
+ * Chess (SrcCD)
+
+ GNU Chess lets most modern computers play a full game of chess. It has
+ a plain terminal interface, a curses interface, & the unique X Windows
+ interface `xboard'. Best results are obtained using GNU C to compile
+ GNU Chess.
+
+ Recent improvements include "configure"-capability, correct thinking on
+ opponent's time, makefile for Windows NT, full Windows 95/NT
+ compatibility, parallel Unix & Windows 95/NT versions, major crash bug
+ fix & various other minor improvements & bug fixes.
+
+ Stuart Cracraft founded GNU Chess & is the project lead for the 10+ year
+ history of GNU Chess. Acknowledgements for this past year's work
+ include Chua Kong Sian, National Supercomputing Research Center,
+ Singapore; & Conor McCarthy, Biomolecular/Biomed Science at Griffith
+ University, Australia.
+
+ Send bugs to `bug-gnu-chess@prep.ai.mit.edu' & general comments to

+ `http://www.win.net/~msm/index.html'. Play GNU Chess on the web at
+ `http://www.delorie.com/game-room/chess'.
+
+ * CLISP (SrcCD)
+
+ CLISP is a Common Lisp implementation by Bruno Haible & Michael Stoll.
+ It mostly supports the Lisp described by `Common LISP: The Language (2nd
+ edition)' & the ANSI Common Lisp standard. CLISP includes an
+ interpreter, a byte-compiler, a large subset of CLOS & a foreign language
+ interface. The user interface language (English, German, French) can be
+ chosen at run time. An X11 API is available through CLX & Garnet.
+ CLISP needs only 2 MB of memory & runs on many microcomputers (including
+ MS-DOS systems, OS/2, Windows NT, Windows 95, Amiga 500-4000, & Acorn
+ RISC PC) & all kinds of Unix systems.
+
+ * Common Lisp *Also *note GNUs Flashes::.* (SrcCD)
+
+ GNU Common Lisp (GCL, formerly known as Kyoto Common Lisp) is a compiler
+ & interpreter for Common Lisp. GCL is very portable & extremely
+ efficient on a wide class of applications, & compares favorably in
+ performance with commercial Lisps on several large theorem-prover &
+ symbolic algebra systems. GCL supports the CLtL1 specification but is
+ moving towards the proposed ANSI standard.
+
+ GCL compiles to C & then uses the native optimizing C compiler (e.g.,
+ GCC). A function with a fixed number of args & one value turns into a C
+ function of the same number of args, returning one value--so GCL is
+ maximally efficient on such calls. Its conservative garbage collector
+ gives great freedom to the C compiler to put Lisp values in registers.
+ It has a source level Lisp debugger for interpreted code & displays
+ source code in an Emacs window. Its profiler (based on the C profiling
+ tools) counts function calls & the time spent in each function.
+
+ There is now a built-in interface to the Tk widget system. It runs in a
+ separate process, so users may monitor progress on Lisp computations or
+ interact with running computations via a windowing interface.
+
+ There is also an Xlib interface via C (xgcl-2). CLX runs with GCL, as
+ does PCL (see "PCL" later in this article).
+
+ GCL version 2.2.1 is released under the GNU Library General Public
+ License.
+
+ * CLX (SrcCD)
+
+ CLX is an X Window interface library for GCL. This is separate from the
+ built-in TK interface.
+
+ * `cpio' (SrcCD)
+
+ `cpio' is an archive program with all the features of SVR4 `cpio',
+ including support for the final POSIX 1003.1 `ustar' standard. `mt', a
+ program to position magnetic tapes, is included with `cpio'.
+
+ * CVS (SrcCD)
+
+ CVS is a version control system (like RCS or SCCS) which allows you to
+ keep old versions of files (usually source code), keep a log of who,
+ when, and why changes occurred, etc. It handles multiple developers,
+ multiple directories, triggers to enable/log/control various operations,
+ and can work over a wide area network. It does not handle build
+ management or bug-tracking; these are handled by `make' and GNATS,
+ respectively.
+
+ * DejaGnu (SrcCD)
+
+ DejaGnu is a framework to test programs with a single front end for all
+ tests. DejaGnu's flexibility & consistency makes it easy to write tests.
+ DejaGnu will also work with remote hosts and embedded systems.
+
+ DejaGnu comes with `expect', which runs scripts to conduct dialogs with
+ programs.
+
+ * Diffutils (SrcCD)
+
+ GNU `diff' compares files showing line-by-line changes in several
+ flexible formats. It is much faster than traditional Unix versions. The
+ Diffutils package has `diff', `diff3', `sdiff', & `cmp'. Future plans
+ include support for internationalization (e.g., error messages in
+ Chinese) & some non-Unix PC environments, & a library interface that can
+ be used by other free software.
+
+ * DJGPP *Also see "GCC" in this article* (BinCD)
+
+ DJ Delorie has ported GCC/G++ to i386s running DOS. DJGPP has a 32-bit
+ i386 DOS extender with a symbolic debugger, development libraries, &
+ ports of Bison, `flex', & Binutils. Full source code is provided. It
+ needs at least 5MB of hard disk space to install & 512K of RAM to use.
+ It supports SVGA (up to 1024x768), XMS & VDISK memory allocation,
+ `himem.sys', VCPI (e.g., QEMM, DESQview, & 386MAX), & DPMI (e.g.,
+ Windows 3.x, OS/2, QEMM, & QDPMI). Version 2 was released in Feb. 1996,
+ & needs a DPMI environment; a free DPMI server is included.
+
+ FTP from `ftp.simtel.net' in `/pub/simtelnet/gnu/djgpp/' (or a SimTel
+ mirror site).
+
+ Ask `listserv@delorie.com', to join a DJGPP users mailing list.
+
+ * `dld' (SrcCD)
+
+ `dld' is a dynamic linker written by W. Wilson Ho. Linking your program
+ with the `dld' library allows you to dynamically load object files into
+ the running binary. `dld' supports a.out object types on the following
+ platforms: Convex C-Series (BSD), i386/i486/Pentium (GNU/Linux), Sequent
+ Symmetry i386 (Dynix 3), Sun-3 (SunOS 3 & 4), Sun-4 (SunOS 4), & VAX
+ (Ultrix).
+
+ * `doschk' (SrcCD)
+
+ This program is a utility to help software developers ensure that their
+ source file names are distinguishable on System V platforms with
+ 14-character filenames and on MS-DOS systems with 8+3 character
+ filenames.
+
+ * `ed' (SrcCD)
+
+ `ed' is the standard text editor. It is line-oriented and can be used
+ interactively or in scripts.
+
+ * Elib (SrcCD)
+
+ Elib is a small library of Emacs Lisp functions, including routines for
+ using AVL trees and doubly-linked lists.
+
+ * Elisp archive (SrcCD)
+
+ This is a snapshot of Ohio State's GNU Emacs Lisp FTP Archive. FTP it
+ from `archive.cis.ohio-state.edu' in `/pub/gnu/emacs/elisp-archive'.
+
+ * Emacs *Also *note Forthcoming GNUs::.* [FSFman(s), FSFrc]
+
+ In 1975, Richard Stallman developed the first Emacs, an extensible,
+ customizable real-time display editor & computing environment. GNU Emacs
+ is his second implementation. It offers true Lisp--smoothly integrated
+ into the editor--for writing extensions & provides an interface to the X
+ Window System. It runs on Unix, MS-DOS, & Windows NT or 95. In
+ addition to its powerful native command set, Emacs can emulate the
+ editors vi & EDT (DEC's VMS editor). Emacs has many other features which
+ make it a full computing support environment. Source for the `GNU Emacs
+ Manual' & a reference card comes with the software. Sources for the
+ `GNU Emacs Lisp Reference Manual', & `Programming in Emacs Lisp: An
+ Introduction' are distributed in separate packages. *Note
+ Documentation::.
+
+ * Emacs 19 (SrcCD) [FSFman(s), FSFrc]
+
+ Emacs 19 works with character-only terminals & with the X Window System
+ (with or without an X toolkit). Features new to Emacs 19 include:
+ multiple X windows ("frames" to Emacs), with a separate X window for the
+ minibuffer or a minibuffer attached to each X window; use of the X
+ toolkit; interfacing with the X resource manager; property lists
+ associated with regions of text in a buffer; multiple fonts & colors
+ defined by those properties; simplified/improved processing of function
+ keys, mouse movement & clicks; X selection processing, including
+ clipboard selections; hooks to be run if the point or mouse moves
+ outside a certain range; menu bars & popup menus defined by keymaps;
+ scrollbars; before- & after-change hooks; a source-level debugger for
+ Emacs Lisp programs; floating point numbers; improved buffer allocation,
+ including returning storage to the system when a buffer is killed; many
+ updated libraries; Autoconf-based configuration; support for version
+ control systems (CVS, RCS, & SCCS); & European character sets.
+
+ Features added recently to Emacs 19 include the ability to open frames
+ on more than one X display from a single Emacs job, operation under
+ MS-DOS, MS Windows, and Windows NT, displaying multiple views of an
+ outline at the same time, Lisp-level timers for real time and idle time,
+ version control support for CVS and for multiple branches, text
+ properties for formatting text, commands to edit text properties and
+ save them in files, and GNU-standard long-named command line options.
+ Also see *Note Forthcoming GNUs::.
+
+ Emacs 19 works on: Acorn RISC (RISCiX); Alliant FX/2800 (BSD); Alpha
+ (OSF/1 or GNU/Linux); Apollo (DomainOS); Bull DPX/2 2nn & 3nn (SysV.3) &
+ sps7 (SysV.2); Clipper; Convex (BSD); Cubix QBx (SysV); Data General

+
+ * Emacs 18 (SrcCD) [FSFrc]
+
+ Emacs 18 is several years old. We no longer maintain it, but still
+ distribute it for those using platforms which Emacs 19 does not support:
+ Alliant FX/80, Altos 3068, Amdahl (UTS), AT&T (3Bs & 7300 PC), CCI 5/32
+ & 6/32, Celerity, DEC (VAX VMS), Dual, Encore (APC, DPC, & XPC), HLH
+ Orion (original & 1/05), ISI (Optimum V, 80386), Masscomp, NCR Tower 32
+ (SVR2 & SVR3), Nixdorf Targon 31, Nu (TI & LMI), pfa50, Plexus, Prime
+ EXL, Stride (system rel. 2), Tahoe, Tandem Integrity S2, Tektronix 16000,
+ Triton 88, Ustation E30 (SS5E), Whitechapel (MG1), & Wicat.
+
+ * `es' (SrcCD)
+
+ `es' is an extensible shell (based on `rc') with first-class functions,
+ lexical scope, exceptions, and rich return values (i.e., functions can
+ return values other than just numbers). `es''s extensibility comes from
+ the ability to modify and extend the shell's built-in services, such as
+ path searching and redirection. Like `rc', it is great for both
+ interactive use and scripting, particularly since its quoting rules are
+ much less baroque than the C and Bourne shells.
+
+ * `enscript' (SrcCD)
+
+ `enscript' is an upwardly-compatible replacement for the Adobe
+ `enscript' program. It formats ASCII files (outputting in Postscript)
+ and stores generated output to a file or sends it directly to the
+ printer.
+
+ * Exim (SrcCD)
+
+ Exim is a new Internet mail transfer agent, similar in style to Smail 3.
+ It can handle relatively high volume mail systems, header rewriting,
+ control over which hosts/nets may use it as a relay, blocking of
+ unwanted mail from specified hosts/nets/senders, and multiple local
+ domains on one mail host ("virtual domains") with several options for
+ the way these are handled.
+
+ * `f2c' *Also see "Fortran" below & in *Note Forthcoming GNUs::*
+ (SrcCD)
+
+ `f2c' converts Fortran-77 source into C or C++, which can be compiled
+ with GCC or G++. Get bug fixes by FTP from site `netlib.bell-labs.com'
+ or by email from `netlib@netlib.bell-labs.com'. For a summary, see the
+ file `/netlib/f2c/readme.Z'.
+
+ * `ffcall' (SrcCD)
+
+ `ffcall' is a C library for implementing foreign function calls in
+ embedded interpreters by Bill Triggs and Bruno Haible. It allows C
+ functions with arbitrary argument lists and return types to be called or
+ emulated (callbacks).
+
+ * Fileutils (SrcCD)
+
+ The Fileutils are: `chgrp', `chmod', `chown', `cp', `dd', `df', `dir',
+ `dircolors', `du', `install', `ln', `ls', `mkdir', `mkfifo', `mknod',
+ `mv', `rm', `rmdir', `sync', `touch', & `vdir'.
+
+ * Findutils (SrcCD)
+
+ `find' is frequently used both interactively and in shell scripts to
+ find files which match certain criteria and perform arbitrary operations
+ on them. Also included are `locate', which scans a database for file
+ names that match a pattern, and `xargs', which applies a command to a
+ list of files.
+
+ * Finger (SrcCD)
+
+ GNU Finger has more features than other finger programs. For sites with
+ many hosts, a single host may be designated as the finger "server" host
+ and other hosts at that site configured as finger "clients". The server
+ host collects information about who is logged in on the clients. To
+ finger a user at a GNU Finger site, a query to any of its client hosts
+ gets useful information. GNU Finger supports many customization
+ features, including user output filters and site-programmable output for
+ special target names.
+
+ * `flex' (BinCD, SrcCD) [FSFman, FSFrc]
+
+ `flex' is a replacement for the `lex' scanner generator. `flex' was
+ written by Vern Paxson of the Lawrence Berkeley Laboratory and generates
+ far more efficient scanners than `lex' does. Sources for the `Flex
+ Manual' and reference card are included (*note Documentation::.).
+
+ * Fortran (`g77') *Also *note Forthcoming GNUs::.* (SrcCD)
+
+ GNU Fortran (`g77'), developed by Craig Burley, is available for public
+ beta testing on the Internet. For now, `g77' produces code that is
+ mostly object-compatible with `f2c' & uses the same run-time library
+ (`libf2c').
+
+ * Fontutils (SrcCD)
+
+ The Fontutils convert between font formats, create fonts for use with
+ Ghostscript or TeX (starting with a scanned type image & converting the
+ bitmaps to outlines), etc. It includes: `bpltobzr', `bzrto',

+ Guide' comes with the software (*note Documentation::.).
+
+ * `gcal' (SrcCD)
+
+ `gcal' is a program for printing calendars. It displays different
+ styled calendar sheets, eternal holiday lists, and fixed date warning
+ lists.
+
+ * GCC *Also *note GNUs Flashes::.* (BinCD, SrcCD) [FSFman]
+
+ Version 2 of the GNU C Compiler supports the languages C, C++, and
+ Objective-C; the source file name suffix or a compiler option selects
+ the language. (Also see "GNAT" later in this article for Ada language
+ supports.) Objective-C support was donated by NeXT. The runtime support
+ needed to run Objective-C programs is now distributed with GCC (this
+ does not include any Objective-C classes aside from `object', but see
+ "GNUstep" in *Note Forthcoming GNUs::). As much as possible, G++ is
+ kept compatible with the evolving draft ANSI standard, but not with
+ `cfront' (AT&T's compiler), which has been diverging from ANSI.
+
+ GCC is a fairly portable optimizing compiler which performs many
+ optimizations. They include: automatic register allocation, common
+ sub-expression elimination (CSE) (including a certain amount of CSE
+ between basic blocks - though not all the supported machine descriptions
+ provide for scheduling or delay slots), invariant code motion from
+ loops, induction variable optimizations, constant propagation, copy
+ propagation, delayed popping of function call arguments, tail recursion
+ elimination, integration of inline functions & frame pointer elimination,
+ instruction scheduling, loop unrolling, filling of delay slots, leaf
+ function optimization, optimized multiplication by constants, the
+ ability to assign attributes to instructions, & many local optimizations
+ automatically deduced from the machine description.
+
+ GCC can open-code most arithmetic on 64-bit values (type `long long
+ int'). It supports extended floating point (type `long double') on the
+ 68k; other machines will follow. GCC supports full ANSI C, traditional
+ C, & GNU C extensions (including: nested functions support, nonlocal
+ gotos, & taking the address of a label).
+
+ GCC can generate a.out, COFF, ELF, & OSF-Rose files when used with a
+ suitable assembler. It can produce debugging information in these
+ formats: BSD stabs, COFF, ECOFF, ECOFF with stabs, & DWARF.
+
+ GCC generates code for many CPUs, including the a29k, Alpha, ARM, AT&T,
+ DSP1610, Clipper, Convex cN, Elxsi, Fujitsu Gmicro, i370, i860, i960,
+ MIL-STD-1750a, MIPS, ns32k, PDP-11, Pyramid, ROMP, RS/6000, SH, SPUR,
+ Tahoe, VAX, & we32k.
+
+ Position-independent code is generated for the Clipper, Hitachi H8/300,
+ HP-PA (1.0 & 1.1), i386/i486/Pentium, m68k, m88k, SPARC, & SPARClite.
+
+ Operating systems supported include: GNU/Hurd, GNU/Linux, ACIS, AIX, AOS,
+ BSD, Clix, Concentrix, Ctix, DG/UX, Dynix, FreeBSD, Genix, HP-UX, Irix,
+ ISC, Luna, LynxOS, Minix, NetBSD, NewsOS, NeXTStep, OS/2, OSF, OSF-Rose,
+ RISCOS, SCO, Solaris 2, SunOS 4, System/370, SysV, Ultrix, Unos, VMS, &
+ Windows/NT.
+
+ Using the configuration scheme for GCC, building a cross-compiler is as
+ easy as building a native compiler.
+
+ Version 1 of GCC, G++, & libg++ are no longer maintained.
+
+ Texinfo source for the `Using and Porting GNU CC' manual is included
+ with GCC (*note Documentation::.).
+
+ * GDB (BinCD, SrcCD) [FSFman, FSFrc]
+
+ GDB, the GNU DeBugger, is a source-level debugger for C, C++, & Fortran.
+ It provides partial support for Modula-2 & Chill.
+
+ GDB can debug both C & C++, & will work with executables made by many
+ different compilers; but, C++ debugging will have some limitations if
+ you do not use GCC.
+
+ GDB has a command line user interface, and Emacs has GDB mode as an
+ interface. Two X interfaces (not distributed or maintained by the FSF)
+ are: `gdbtk' (FTP it from `ftp.cygnus.com' in directory `/pub/gdb'); and
+ `xxgdb' (FTP it from `ftp.x.org' in directory `/contrib/utilities').
+
+ Executable files and symbol tables are read via the BFD library, which
+ allows a single copy of GDB to debug programs with multiple object file
+ formats (e.g., a.out, COFF, ELF). Other features include a rich command
+ language, remote debugging over serial lines or TCP/IP, and watchpoints
+ (breakpoints triggered when the value of an expression changes).
+
+ GDB uses a standard remote interface to a simulator library which (so
+ far) has simulators for the ARM, Hitachi H8/300, Hitachi H8/500, Hitachi
+ Super-H, PowerPC, WDC 65816, & Zilog Z8001/2.
+
+ GDB can perform cross-debugging. To say that GDB "targets" a platform
+ means it can perform native or cross-debugging for it. To say that GDB
+ can "host" a given platform means that it can be built on it, but cannot
+ necessarily debug native programs.
+
+ GDB can:
+
+ * "target" & "host": Amiga 3000 (Amix, NetBSD), DEC Alpha (OSF/1),
+ DECstation 3100 & 5000 (Ultrix), HP 9000/300 (BSD, HP-UX), HP

+ libraries. It implements a database using quick lookup by hashing.
+ `gdbm' does not ordinarily make sparse files (unlike its Unix and BSD
+ counterparts).
+
+ * `gettext' *Also *note Help the GNU Translation Project::.* (SrcCD)
+
+ The GNU `gettext' tool set has everything maintainers need to
+ internationalize a package's user messages. Once a package has been
+ internationalized, `gettext''s many tools help translators localize
+ messages to their native language and automate handling the translation
+ files.
+
+ * Generic NQS (SrcCD)
+
+ Generic NQS is a network queuing system for spreading batch jobs across a
+ network of machines. It is designed to be simple to install on a
+ heterogeneous network of machines, and has optimizations for running on

+ market. It is available for many more UNIX variants than any other
+ comparable product, and inter-operates with other NQS systems, including
+ Cray's NQE.
+
+ * `geomview' *See* `http://www.geom.umn.edu/software/geomview' (SrcCD)
+
+ `geomview' is an interactive geometry viewing program, for UNIX systems
+ with Motif, using X, GL, or OpenGL graphics. It allows multiple
+ independently controllable objects and cameras. `geomview' provides
+ interactive control for motion, appearances (including lighting,
+ shading, and materials), picking on an object, edge or vertex level, and
+ snapshots in PPM or SGI image files, Postscript, and Renderman RIB
+ format. `geomview' can be controlled through direct mouse manipulation,
+ control panels, and keyboard shortcuts. External programs can also
+ drive desired aspects of the viewer (such as continually loading
+ changing geometry or controlling the motion of certain objects) while
+ allowing interactive control of everything else.
+
+ * `gforth' (SrcCD)
+
+ `gforth' is a fast, portable implementation of the ANS Forth language.

+ new features include: support for anti-aliased characters; the ability
+ to scan a directory and register all the fonts in it; support for Type 0
+ (Japanese / Chinese / Korean) fonts; and the ability to compile all the
+ external initialization files into the executable. This version can
+ also run as a 32-bit MS Windows application.
+
+ Thanks to the generosity of URW++ (Hamburg, Germany), the low-quality
+ bitmap-derived fonts distributed with older versions have been replaced
+ with commercial-quality, hinted outline fonts.
+
+ Ghostscript executes commands in the Postscript language by writing
+ directly to a printer, drawing on an X window, or writing to files for
+ printing later or manipulating with other graphics programs.
+
+ Ghostscript includes a C-callable graphics library (for client programs
+ that do not want to deal with the Postscript language). It also supports
+ i386/i486/Pentiums running DOS with EGA, VGA or SuperVGA graphics (but
+ please do *not* ask the FSF staff any questions about this; we do not
+ use DOS).
+
+ * Ghostview (SrcCD)

+ chosen GNU Ada 95 as the Ada compiler for their systems. GNAT is
+ maintained by Ada Core Technologies. For more information, see
+ `http://www.gnat.com'.
+
+ * GNATS (SrcCD)
+
+ GNATS, GNats: A Tracking System, is a bug-tracking system. It is based
+ upon the paradigm of a central site or organization which receives
+ problem reports and negotiates their resolution by electronic mail.

+ `mccallum@gnu.ai.mit.edu'. See "GNUstep" in *Note Forthcoming GNUs::.
+
+ * OBST (SrcCD)
+
+ OBST is a persistent object management system with bindings to C++.
+ OBST supports incremental loading of methods. Its graphical tools
+ require the X Window System. It features a hands-on tutorial including
+ sample programs. It compiles with G++, and should install easily on
+ most Unix platforms.
+
+ * Octave *Also see* `http://www.che.wisc.edu/octave' (SrcCD)
+
+ Octave does arithmetic for real and complex scalars and matrices, solves
+ sets of nonlinear algebraic equations, integrates systems of ordinary
+ differential & differential-algebraic equations, and integrates
+ functions over finite & infinite intervals. Two- & three-dimensional
+ plotting is available using `gnuplot'.
+
+ Version 2.0 of Octave was released in December '96. It includes support
+ for dynamically linked functions, user-defined data types, many new
+ functions, & a completely revised manual. Octave works on most Unix
+ systems & OS/2. A port to Windows NT/95 is underway.
+
+ * Oleo (SrcCD)
+
+ Oleo is a spreadsheet program (better for you than the more expensive
+ spreadsheets). It supports the X Window System and character-based
+ terminals, and can output Embedded Postscript renditions of spreadsheets.
+ Keybindings should be familiar to Emacs users and are configurable.
+ Oleo supports multiple variable-width fonts when used under the X Window
+ System or outputting to Postscript devices.
+
+ * `p2c' (SrcCD)
+
+ `p2c' is Dave Gillespie's Pascal-to-C translator. It inputs many
+ dialects (HP, ISO, Turbo, VAX, etc.) & generates readable,
+ maintainable, portable C.
+
+ * `patch' (SrcCD)
+
+ `patch' is our version of Larry Wall's program to take `diff''s output
+ and apply those differences to an original file to generate the modified
+ version.
+
+ * PCL (SrcCD)
+
+ PCL is a free implementation of a large subset of CLOS, the Common Lisp
+ Object System. It runs under both GCL and CLISP, mentioned above.
+
+ * `perl' (SrcCD)

+ Larry Wall's `perl' combines the features & capabilities of C, `sed',
+ `awk', & `sh', and provides interfaces to the Unix system calls & many C
+ library routines.
+
+ * `pine' *Also *note Bad News and Good News about Pine::.* (SrcCD)
+
+ `pine' is a friendly menu-driven electronic mail manager and user
+ interface.
+
+ * `ptx' *Also *note Forthcoming GNUs::.* (SrcCD)
+
+ GNU `ptx' is our version of the traditional permuted index generator.
+ It handles multiple input files at once, has TeX compatible output, &
+ outputs readable "KWIC" (KeyWords In Context) indexes without using
+ `nroff'.
+
+ It does not yet handle input files that do not fit in memory all at once.
+
+ * `rc' (SrcCD)
+
+ `rc' is a shell that features a C-like syntax (much more so than `csh')
+ and far cleaner quoting rules than the C or Bourne shells. It's
+ intended to be used interactively, but is also great for writing
+ scripts. It inspired the shell `es'.
+
+ * RCS (SrcCD)
+
+ RCS, the Revision Control System, is used for version control &
+ management of software projects. Used with GNU `diff', RCS can handle
+ binary files (8-bit data, executables, object files, etc). RCS now
+ conforms to GNU configuration standards & to POSIX 1003.1b-1993. Also
+ see the CVS item above.
+
+ * `recode' *Also *note Forthcoming GNUs::.* (SrcCD)
+
+ GNU `recode' converts files between character sets and usages. When
+ exact transliterations are not possible, it may delete the offending

+ outputs nearly 150 different character sets and is able to transliterate
+ files between almost any pair. Most RFC 1345 character sets are
+ supported.
+
+ * `regex' (SrcCD)
+
+ The GNU regular expression library supports POSIX.2, except for
+ internationalization features. It is included in many GNU programs which
+ do regular expression matching & is available separately. An alternate
+ regular expression package, `rx', is faster than `regex' in many cases;
+ we were planning to replace `regex' with `rx', but it is not certain
+ this will happen.
+
+ * Roxen (SrcCD)
+
+ Roxen is a modularized, object-oriented, non-forking World Wide Web
+ server with high performance and throughput. It was formerly named
+ Spinner, but was renamed for trademark reasons.
+
+ * `rx' (SrcCD)
+
+ Tom Lord has written `rx', a new regular expression library which is
+ faster than the older GNU `regex' library. It is being distributed with
+ `sed'. `rx' is also an installation option for `fileutils', `id-utils',
+ and `textutils', and maybe for future versions of `cpio', `m4' and `ptx'.
+
+ * SAOimage (SrcCD)
+
+ SAOimage is an X-based astronomical image viewer. It reads array data
+ images, which may be in specific formats, and displays them with a
+ pseudocolor colormap. There is full interactive control of the
+ colormap, panning and zooming, graphical annotation, and cursor tracking
+ in pixel and sky coordinates, among other features.
+
+ * Scheme (SrcCD)
+
+ Scheme is a simplified, lexically-scoped dialect of Lisp. It was
+ designed at MIT and other universities to teach students the art of
+ programming and to research new parallel programming constructs and
+ compilation techniques.
+
+ We now distribute MIT Scheme 7.3, which conforms to the "Revised^4
+ Report On the Algorithmic Language Scheme" (MIT AI Lab Memo 848b), for
+ which TeX source is included. It is written partly in C, but is
+ presently hard to bootstrap. Binaries to bootstrap it exist for: HP9000
+ series 300, 400, 700, & 800 (running HP-UX 9.0), NeXT (NeXT OS 2 or 3.2),
+ DEC Alpha (OSF/1), IBM RS/6000 (AIX), Sun-3 or Sun-4 (SunOS 4.1),
+ DECstation 3100/5100 (Ultrix 4.0), Sony NeWS-3250 (NEWS OS 5.01), &
+ Intel i386 (MS-DOS, Windows 3.1 or NT). If your system isn't on this
+ list & you don't enjoy the bootstrap challenge, see "JACAL" earlier in
+ this article.
+
+ * `screen' (SrcCD)
+
+ `screen' is a terminal multiplexer that runs several separate "screens"
+ (ttys) on a single character-based terminal. Each virtual terminal
+ emulates a DEC VT100 plus several ISO 2022 and ISO 6429 (ECMA 48, ANSI
+ X3.64) functions, including color. Arbitrary keyboard input translation
+ is also supported. `screen' sessions can be detached and resumed later
+ on a different terminal type. Output in detached sessions is saved for
+ later viewing.
+
+ * `sed' (SrcCD)
+
+ `sed' is a stream-oriented version of `ed'. It comes with the `rx'
+ library.
+
+ * Sharutils (SrcCD)
+
+ `shar' makes so-called shell archives out of many files, preparing them
+ for transmission by electronic mail services; `unshar' helps unpack
+ these shell archives after reception. `uuencode' and `uudecode' are
+ POSIX compliant implementations of a pair of programs which transform
+ files into a format that can be safely transmitted across a 7-bit ASCII
+ link.
+

+ GNU Shogi is a variant of GNU Chess; it implements the same features &
+ similar heuristics. As a new feature, sequences of partial board
+ patterns can be introduced to help the program play toward specific
+ opening patterns. It has both character and X display interfaces.
+
+ It is primarily supported by Matthias Mutz on behalf of the FSF.
+
+ * SIPP (SrcCD)
+
+ SIPP is a library for photorealisticly rendering 3D scenes. Scenes can
+ be illuminated by an arbitrary number of light sources; they are built up
+ of object hierarchies, with arbitrarily many subobjects and subsurfaces.
+ Surfaces can be rendered with either Phong, Gouraud, or flat shading.
+ The library supports programmable shaders and texture mapping.
+
+ * Smail (SrcCD)
+
+ Smail is a mail transport system, designed as a compatible drop-in
+ replacement for `sendmail'. It uses a much simpler configuration format
+ than `sendmail' and is designed to be setup with minimal effort.
+
+ * Smalltalk *Also *note Forthcoming GNUs::.* (SrcCD)
+
+ GNU Smalltalk is an interpreted object-oriented programming language
+ system written in highly portable C. It has been ported to DOS, many
+ Unix, & other OSes. Features include a binary image save capability,
+ the ability to call user-written C code with parameters, an Emacs
+ editing mode, a version of the X protocol invocable from Smalltalk,
+ optional byte-code compilation and/or execution tracing, & automatically

+ * Superopt (SrcCD)
+
+ Superopt is a function sequence generator that uses an exhaustive
+ generate-and-test approach to find the shortest instruction sequence for
+ a given function. You provide a function as input, a CPU to generate
+ code for, and how many instructions you want. Its use in GCC is
+ described in the `ACM SIGPLAN PLDI'92 Proceedings'. It supports: SPARC,
+ m68k, m68020, m88k, IBM POWER and PowerPC, AMD 29k, Intel x86 & 960,
+ Pyramid, DEC Alpha, Hitachi SH, & HP-PA.
+

+ * `tar' (SrcCD)
+
+ GNU `tar' includes multi-volume support, the ability to archive sparse
+ files, compression/decompression, remote archives, and special features
+ that allow `tar' to be used for incremental and full backups. GNU `tar'
+ uses an early draft of the POSIX 1003.1 `ustar' format which is
+ different from the final version. This will be corrected in the future.
+
+ * Termcap Library (SrcCD) [FSFman]
+
+ The GNU Termcap library is a drop-in replacement for `libtermcap.a' on
+ any system. It does not place an arbitrary limit on the size of Termcap
+ entries, unlike most other Termcap libraries. Included is source for the
+ `Termcap Manual' in Texinfo format (*note Documentation::.).
+
+ * Termutils (SrcCD)
+

+CD-ROMs
+*******
+
+We offer these CD-ROMs:
+
+ * Several editions of our *Note Source Code CD-ROMs::.
+
+ * January 1997 *Note Compiler Tools Binaries CD-ROM::.
+
+ * December 1995 Compiler Tools Binaries CD-ROM, see the *note Free
+ Software Foundation Order Form::.
+
+ * December 1994 Compiler Tools Binaries CD-ROM, see the *note Free
+ Software Foundation Order Form::.
+
+ * December 1993 Compiler Tools Binaries CD-ROM, see the *note Free
+ Software Foundation Order Form::.
+
+Our CDs are in ISO 9660 format & can be mounted as a read-only file system on
+most computers. If your driver supports it, you can mount each CD with "Rock
+Ridge" extensions & it will look like a regular Unix file system, rather than
+one full of truncated & otherwise mangled names that fit vanilla ISO 9660.
+
+You can build most of the software without copying the sources off the CD.
+You only need enough disk space for object files and intermediate build
+targets.
+
+
+
+Pricing of the GNU CD-ROMs
+--------------------------
+
+If a business or organization is ultimately paying, the January 1997 Source CD
+set costs $240. The set costs $60 if you, an individual, are paying out of
+your own pocket. The January 1997 Compiler Tools Binaries CD-ROM costs $220
+for a business or organization, and $55 for an individual.
+
+
+
+What Do the Different Prices Mean?
+..................................
+
+The software on our disks is free; anyone can copy it and anyone can run it.
+What we charge for is the physical disk and the service of distribution.
+
+We charge two different prices depending on who is buying. When a company or
+other organization buys the January 1997 Source CD-ROMs, we charge $240.
+When an individual buys the same CD-ROMs, we charge just $60. This
+distinction is not a matter of who is allowed to use the software. In either
+case, once you have a copy, you can distribute as many copies as you wish and
+there's no restriction on who can have or run them. The price distinction is
+entirely a matter of what kind of entity pays for the CDs.
+
+You, the reader, are certainly an individual, not a company. If you are
+buying a disk "in person", then you are probably doing so as an individual.
+But if you expect to be reimbursed by your employer, then the disk is really
+for the company; so please pay the company price and get reimbursed for it.
+We won't try to check up on you--we use the honor system--so please cooperate.
+
+Buying CDs at the company price is very helpful for GNU; just
+150 Source CDs at that price support an FSF programmer or tech writer for a
+year.
+
+
+
+Why Is There an Individual Price?
+.................................
+
+In the past, our distribution tapes were ordered mainly by companies. The CD
+at the price of $240 provides them with all of our software for a much lower
+price than they would previously have paid for six different tapes. To lower
+the price more would cut into the FSF's funds very badly and decrease the
+software development we can do.
+
+However, for individuals, $240 is too high a price; hardly anyone could
+afford that. So we decided to make CDs available to individuals at the lower
+price of $60.
+
+
+
+Is There a Maximum Price?
+.........................
+
+Our stated prices are minimum prices. Feel free to pay a higher price if you
+wish to support GNU development more. The sky's the limit; we will accept as
+high a price as you can offer. Or simply give a donation (tax-deductible in
+the U.S.) to the Free Software Foundation, a tax-exempt public charity.
+
+
+
+January 1997 Compiler Tools Binaries CD-ROM
+-------------------------------------------
+
+The fourth edition of our CD-ROM that has binaries and complete sources for
+GNU compiler tools for some systems which lack a compiler, will be available
+at the end of January 1997. This enables the people who use these systems to
+compile GNU and other free software without having to buy a proprietary
+compiler. You can also use these GNU tools to compile your own
+C/C++/Objective-C programs. Older editions of this CD are available while
+supplies last at a reduced price; see the *note Free Software Foundation
+Order Form::.
+
+We hope to have more systems on each update of this CD. If you can help
+build binaries for new systems (especially those that don't come with a C
+compiler), or have one to suggest, please contact us at the addresses on the
+top menu.
+
+These packages:
+
+ * DJGPP
+ * GCC/G++/Objective-C
+ * GNU C Library
+ * GDB
+ * Binutils
+ * Bison
+ * Emacs (MS-DOS only)
+ * Flex
+ * Make
+ * libg++
+
+On these platforms:
+
+ * `i386-msdos'
+ * `hppa1.1-hp-hpux9'
+ * `hppa1.1-hp-hpux10'
+ * `powerpc-ibm-aix4.2'
+ * `sparc-sun-solaris2.4'
+ * `sparc-sun-solaris2.5'
+ * `sparc-sun-sunos4.1'
+
+
+

+ * October 1992 Source Code CD-ROM, see the *note Free Software Foundation
+ Order Form::.
+
+The older Source CDs are available while supplies last at a reduced price
+(please note that the December 1994 Source CD is permanently out of stock).
+All the Source CDs have Texinfo source for the GNU manuals listed in *Note
+Documentation::.
+
+MIT Scheme & much of X11 is *not* on the older Source CDs.
+
+There are no precompiled programs on these Source CDs. You will need a C
+compiler (programs which need some other interpreter or compiler normally
+provide the C source for a bootstrapping program). We ship C compiler
+binaries for some systems on the *Note Compiler Tools Binaries CD-ROM::.
+
+
+
+January 1997 Source Code CD-ROMs
+................................
+
+The 9th edition of our Source Code CD will be available at the end of January
+1997 with two CD-ROM disks. It has programs, bug fixes, & improvements not
+on the older Source CDs. It has these packages, & some manuals that are not
+part of packages. The version number of each package listed might be higher
+on the 9th edition CD due to new releases being made between now and then.

+CD-ROM Subscription Service
+***************************
+
+Our subscription service enables you to stay current with the latest GNU
+developments. For a one-time cost equivalent to three Source CD-ROMs (plus
+shipping in some cases), we will ship you four new versions of the *Note
+Source Code CD-ROMs::. The CD-ROMs are sent as they are issued (currently
+twice a year, but we hope to make it more frequent). We do not yet know if
+we will be offering subscriptions to the Compiler Tools Binaries CD.
+
+A subscription is an easy way to keep up with the regular bug fixes to the X
+Window System. Each edition of the *Note Source Code CD-ROMs::, has updated
+sources for the X Window System.
+
+Please note: In two cases, you must pay 4 times the normal shipping required
+for a single order when you pay for each subscription. If you're in Alaska,
+Hawaii, or Puerto Rico you must add $20.00 for shipping for each
+subscription. If you're outside of the U.S., Canada, and Puerto Rico, you
+must add $80.00 for each subscription. See "CD-ROMs" and "Tax and Shipping
+Costs" on the *note Free Software Foundation Order Form::.
+
+
+
+FSF T-shirt
+***********
+
+The front of our T-shirt has the GNU Emacs Lisp code `(USE 'GNU)' with "`()'"
+being the dancing parentheses from the cover of our `GNU Emacs Lisp Reference
+Manual' (drawn by Berkeley, CA artist Etienne Suvasa). The shirt's back has
+the Preamble to the GNU General Public License.
+
+These shirts come in black, purple, red, pink, burgundy, blue, and natural
+(off-white). When you order, please give 3 choices. Black and purple are
+printed in white; the other colors are printed in black. All shirts are
+thick 100% cotton, and come in sizes S, M, L, XL, and XXL (but they run small
+so you may want a larger size than usual).
+
+GNU T-shirts often create spontaneous friendships at conferences & on
+university campuses. They also make great gifts for friends & family,
+including children!

+This directory contains the version 2.7.2 release of the GNU C
+compiler. It includes all of the support for compiling C++ and
+Objective C, including a run-time library for Objective C.
+
+The GNU C compiler is free software. See the file COPYING for copying
+permission.
+
+See the file gcc.texi (together with other files that it includes) for
+installation and porting information. The file INSTALL contains a
+copy of the installation information, as plain ASCII.
+
+Installing this package will create various files in subdirectories of
+/usr/local/lib, which are passes used by the compiler and a library
+named libgcc.a. It will also create /usr/local/bin/gcc, which is
+the user-level command to do a compilation.
+
+See the Bugs chapter of the GCC Manual for how to report bugs
+usefully. An online readable version of the manual is in the files
+gcc.info*.
+
+The files pself.c and pself1.c are not part of GCC.
+They are programs that print themselves on standard output.
+They were written by Dario Dariol and Giovanni Cozzi, and are
+included for your hacking pleasure. Likewise pself2.c
+(Who is the author of that?) and pself3.c (by Vlad Taeerov and Rashit

+no change whatever*, when installed following the precise
+recommendations that come with the distribution.
+
+Here are some guidelines on how to do pretesting so as to make it
+helpful. All of them follow from common sense together with the
+nature of the purpose and the situation.
+
+* It is absolutely vital that you mention even the smallest change or
+departure from the standard sources and installation procedure.
+
+Otherwise, you are not testing the same program that I wrote. Testing
+a different program is usually of no use whatever. It can even cause
+trouble if you fail to tell me that you tested some other program
+instead of what I know as GCC. I might think that GCC works, when in
+fact it has not been properly tried, and might have a glaring fault.
+
+* Even changing the compilation options counts as a change in the
+program. The GCC sources specify which compilation options to use.
+Some of them are specified in makefiles, and some in machine-specific
+configuration files.
+
+You have ways to override this--but if you do, then you are not
+testing what ordinary users will do. Therefore, when pretesting, it
+is vital to test with the default compilation options.
+
+(It is okay to test with nonstandard options as well as testing with
+the standard ones.)
+
+* The machine and system configuration files of GCC are parts of
+GCC. So when you test GCC, you need to do it with the
+configuration files that come with GCC.
+
+If GCC does not come with configuration files for a certain machine,
+and you test it with configuration files that don't come with GCC,
+this is effectively changing GCC. Because the crucial fact about
+the planned release is that, without changes, it doesn't work on that
+machine.
+
+To make GCC work on that machine, I would need to install new
+configuration files. That is not out of the question, since it is
+safe--it certainly won't break any other machines that already work.
+But you will have to rush me the legal papers to give the FSF
+permission to use a large piece of text.
+
+* Look for recommendations for your system.
+
+You can find these recommendations in the Installation node of the
+manual, and in the file INSTALL. (These two files have the same text.)
+
+These files say which configuration name to use for your machine, so
+use the ones that are recommended. If you guess, you might guess
+wrong and encounter spurious difficulties. What's more, if you don't
+follow the recommendations then you aren't helping to test that its
+recommendations are valid.
+
+These files may describe other things that you need to do to make GCC
+work on your machine. If so, you should follow these recommendations
+also, for the same reason.
+
+Also look at the Trouble chapter of the manual for items that
+pertain to your machine.
+
+* Don't delay sending information.
+
+When you find a problem, please double check it if you can do so
+quickly. But don't spend a long time double-checking. A good rule is
+always to tell me about every problem on the same day you encounter
+it, even if that means you can't find a solution before you report the
+problem.
+
+I'd much rather hear about a problem today and a solution tomorrow
+than get both of them tomorrow at the same time.
+
+* Make each bug report self-contained.
+
+If you refer back to another message, whether from you or from someone
+else, then it will be necessary for anyone who wants to investigate
+the bug to find the other message. This may be difficult, it is
+probably time-consuming.
+
+To help me save time, simply copy the relevant parts of any previous
+messages into your own bug report.
+
+In particular, if I ask you for more information because a bug report
+was incomplete, it is best to send me the *entire* collection of
+relevant information, all together. If you send just the additional
+information, that makes me do extra work. There is even a risk that
+I won't remember what question you are sending me the answer to.
+
+* Always be precise when talking about changes you have made. Show
+things rather than describing them. Use exact filenames (relative to
+the main directory of the distribution), not partial ones. For
+example, say "I changed Makefile" rather than "I changed the
+makefile". Instead of saying "I defined the MUMBLE macro", send a
+diff that shows your change.
+
+* Always use `diff -c' to make diffs. If you don't include context,
+it may be hard for me to figure out where you propose to make the
+changes. I might have to ignore your patch because I can't tell what
+it means.
+
+* When you write a fix, keep in mind that I can't install a change
+that would break other systems.
+
+People often suggest fixing a problem by changing machine-independent
+files such as toplev.c to do something special that a particular
+system needs. Sometimes it is totally obvious that such changes would
+break GCC for almost all users. I can't possibly make a change like
+that. All I can do is send it back to you and ask you to find a fix
+that is safe to install.
+
+Sometimes people send fixes that *might* be an improvement in
+general--but it is hard to be sure of this. I can install such
+changes some of the time, but not during pretest, when I am trying to
+get a new version to work reliably as quickly as possible.
+
+The safest changes for me to install are changes to the configuration
+files for a particular machine. At least I know those can't create
+bugs on other machines.
+
+* Don't try changing GCC unless it fails to work if you don't change it.
+
+* Don't even suggest changes that would only make GCC cleaner.
+Every change I install could introduce a bug, so I won't install
+a change unless I see it is necessary.
+
+* If you would like to suggest changes for purposes other than fixing
+serious bugs, don't wait till pretest time. Instead, send them just
+after I make a release. That's the best time for me to install them.
+
+* In some cases, if you don't follow these guidelines, your
+information might still be useful, but I might have to do more work to
+make use of it. Unfortunately, I am so far behind in my work that I
+just can't get the job done unless you help me to do it efficiently.
+
+
+ Thank you

+GNU Service Directory
+---------------------
+
+This is a list of people who have asked to be listed as offering
+support services for GNU software, including GNU Emacs, for a fee
+or in some cases at no charge.
+
+The information comes from the people who asked to be listed;
+we do not include any information we know to be false, but we
+cannot check out any of the information; we are transmitting it to
+you as it was given to us and do not promise it is correct.
+Also, this is not an endorsement of the people listed here.
+We have no opinions and usually no information about the abilities of
+any specific person. We provide this list to enable you to contact
+service providers and decide for yourself whether to hire one.
+
+Before FSF will list your name in the GNU Service Directory, we ask
+that you agree informally to the following terms:
+
+1. You will not restrict (except by copyleft) the use or distribution
+of any software, documentation, or other information you supply anyone
+in the course of modifying, extending, or supporting GNU software.
+This includes any information specifically designed to ameliorate the
+use of GNU software.
+
+2. You will not take advantage of contact made through the Service
+Directory to advertise an unrelated business (e.g., sales of
+non-GNU-related proprietary information). You may spontaneously
+mention your availability for general consulting, but you should not
+promote a specific unrelated business unless the client asks.
+
+Please include some indication of your rates, because otherwise users
+have nothing to go by. Please put each e-mail address inside "<>".
+Please put nothing else inside "<>". Thanks!

+This is a collection of things that test suites have
+said were "wrong" with GCC--but that I don't agree with.
+
+First, test suites sometimes test for compatibility with
+traditional C. GCC with -traditional is not completely
+compatible with traditional C, and in some ways I think it
+should not be.
+
+* K&R C allowed \x to appear in a string literal (or character
+literal?) even in cases where it is *not* followed by a sequence of
+hex digits. I'm not convinced this is desirable.
+
+* K&R compilers allow comments to cross over an inclusion boundary (i.e.
+started in an include file and ended in the including file).
+I think this would be quite ugly and can't imagine it could
+be needed.
+
+Sometimes tests disagree with GCC's interpretation of the ANSI standard.
+
+* One test claims that this function should return 1.
+
+ enum {A, B} foo;
+
+ func (enum {B, A} arg)
+ {
+ return B;
+ }
+
+I think it should return 0, because the definition of B that
+applies is the one in func.
+
+* Some tests report failure when the compiler does not produce
+an error message for a certain program.
+
+ANSI C requires a "diagnostic" message for certain kinds of invalid
+programs, but a warning counts as a diagnostic. If GCC produces
+a warning but not an error, that is correct ANSI support.
+When test suites call this "failure", the tests are broken.

+.SH DESCRIPTION
+The C preprocessor is a \c
+.I macro processor\c
+\& that is used automatically by
+the C compiler to transform your program before actual compilation. It is
+called a macro processor because it allows you to define \c
+.I macros\c
+\&,
+which are brief abbreviations for longer constructs.
+
+The C preprocessor provides four separate facilities that you can use as
+you see fit:
+.TP
+\(bu
+Inclusion of header files. These are files of declarations that can be
+substituted into your program.
+.TP
+\(bu
+Macro expansion. You can define \c
+.I macros\c
+\&, which are abbreviations
+for arbitrary fragments of C code, and then the C preprocessor will
+replace the macros with their definitions throughout the program.
+.TP
+\(bu
+Conditional compilation. Using special preprocessing directives, you
+can include or exclude parts of the program according to various
+conditions.
+.TP
+\(bu
+Line control. If you use a program to combine or rearrange source files into
+an intermediate file which is then compiled, you can use line control
+to inform the compiler of where each source line originally came from.
+.PP
+C preprocessors vary in some details. For a full explanation of the
+GNU C preprocessor, see the
+.B info
+file `\|\c
+.B cpp.info\c
+\&\|', or the manual
+.I The C Preprocessor\c
+\&. Both of these are built from the same documentation source file, `\|\c
+.B cpp.texinfo\c
+\&\|'. The GNU C
+preprocessor provides a superset of the features of ANSI Standard C.
+
+ANSI Standard C requires the rejection of many harmless constructs commonly
+used by today's C programs. Such incompatibility would be inconvenient for
+users, so the GNU C preprocessor is configured to accept these constructs
+by default. Strictly speaking, to get ANSI Standard C, you must use the
+options `\|\c
+.B \-trigraphs\c
+\&\|', `\|\c
+.B \-undef\c
+\&\|' and `\|\c
+.B \-pedantic\c
+\&\|', but in
+practice the consequences of having strict ANSI Standard C make it
+undesirable to do this.
+
+Most often when you use the C preprocessor you will not have to invoke it
+explicitly: the C compiler will do so automatically. However, the
+preprocessor is sometimes useful individually.
+
+When you call the preprocessor individually, either name
+(\c
+.B cpp\c
+\& or \c
+.B cccp\c
+\&) will do\(em\&they are completely synonymous.
+
+The C preprocessor expects two file names as arguments, \c
+.I infile\c
+\& and
+\c
+.I outfile\c
+\&. The preprocessor reads \c
+.I infile\c
+\& together with any other
+files it specifies with `\|\c
+.B #include\c
+\&\|'. All the output generated by the
+combined input files is written in \c
+.I outfile\c
+\&.
+
+Either \c
+.I infile\c
+\& or \c
+.I outfile\c
+\& may be `\|\c
+.B \-\c
+\&\|', which as \c
+.I infile\c
+\&
+means to read from standard input and as \c
+.I outfile\c
+\& means to write to
+standard output. Also, if \c
+.I outfile\c
+\& or both file names are omitted,
+the standard output and standard input are used for the omitted file names.
+.SH OPTIONS
+Here is a table of command options accepted by the C preprocessor.
+These options can also be given when compiling a C program; they are
+passed along automatically to the preprocessor when it is invoked by
+the compiler.
+.TP
+.B \-P
+Inhibit generation of `\|\c
+.B #\c
+\&\|'-lines with line-number information in
+the output from the preprocessor. This might be
+useful when running the preprocessor on something that is not C code
+and will be sent to a program which might be confused by the
+`\|\c
+.B #\c
+\&\|'-lines.
+.TP
+.B \-C
+Do not discard comments: pass them through to the output file.
+Comments appearing in arguments of a macro call will be copied to the
+output before the expansion of the macro call.
+.TP
+.B \-traditional
+Try to imitate the behavior of old-fashioned C, as opposed to ANSI C.
+.TP
+.B \-trigraphs
+Process ANSI standard trigraph sequences. These are three-character
+sequences, all starting with `\|\c
+.B ??\c
+\&\|', that are defined by ANSI C to
+stand for single characters. For example, `\|\c
+.B ??/\c
+\&\|' stands for
+`\|\c
+.BR "\e" "\|',"
+so `\|\c
+.B '??/n'\c
+\&\|' is a character constant for a newline.
+Strictly speaking, the GNU C preprocessor does not support all
+programs in ANSI Standard C unless `\|\c
+.B \-trigraphs\c
+\&\|' is used, but if
+you ever notice the difference it will be with relief.
+
+You don't want to know any more about trigraphs.
+.TP
+.B \-pedantic
+Issue warnings required by the ANSI C standard in certain cases such
+as when text other than a comment follows `\|\c
+.B #else\c
+\&\|' or `\|\c
+.B #endif\c
+\&\|'.
+.TP
+.B \-pedantic\-errors
+Like `\|\c
+.B \-pedantic\c
+\&\|', except that errors are produced rather than
+warnings.
+.TP
+.B \-Wtrigraphs
+Warn if any trigraphs are encountered (assuming they are enabled).
+.TP
+.B \-Wcomment
+.TP
+.B \-Wcomments
+Warn whenever a comment-start sequence `\|\c
+.B /*\c
+\&\|' appears in a comment.
+(Both forms have the same effect).
+.TP
+.B \-Wall
+Requests both `\|\c
+.B \-Wtrigraphs\c
+\&\|' and `\|\c
+.B \-Wcomment\c
+\&\|' (but not
+`\|\c
+.B \-Wtraditional\c
+\&\|').
+.TP
+.B \-Wtraditional
+Warn about certain constructs that behave differently in traditional and
+ANSI C.
+.TP
+.BI "\-I " directory\c
+\&
+Add the directory \c
+.I directory\c
+\& to the end of the list of
+directories to be searched for header files.
+This can be used to override a system header file, substituting your
+own version, since these directories are searched before the system
+header file directories. If you use more than one `\|\c
+.B \-I\c
+\&\|' option,
+the directories are scanned in left-to-right order; the standard
+system directories come after.
+.TP
+.B \-I\-
+Any directories specified with `\|\c
+.B \-I\c
+\&\|' options before the `\|\c
+.B \-I\-\c
+\&\|'
+option are searched only for the case of `\|\c
+.B #include "\c
+.I file\c
+\&"\c
+\&\|';
+they are not searched for `\|\c
+.B #include <\c
+.I file\c
+\&>\c
+\&\|'.
+
+If additional directories are specified with `\|\c
+.B \-I\c
+\&\|' options after
+the `\|\c
+.B \-I\-\c
+\&\|', these directories are searched for all `\|\c
+.B #include\c
+\&\|'
+directives.
+
+In addition, the `\|\c
+.B \-I\-\c
+\&\|' option inhibits the use of the current
+directory as the first search directory for `\|\c
+.B #include "\c
+.I file\c
+\&"\c
+\&\|'.
+Therefore, the current directory is searched only if it is requested
+explicitly with `\|\c
+.B \-I.\c
+\&\|'. Specifying both `\|\c
+.B \-I\-\c
+\&\|' and `\|\c
+.B \-I.\c
+\&\|'
+allows you to control precisely which directories are searched before
+the current one and which are searched after.
+.TP
+.B \-nostdinc
+Do not search the standard system directories for header files.
+Only the directories you have specified with `\|\c
+.B \-I\c
+\&\|' options
+(and the current directory, if appropriate) are searched.
+.TP
+.B \-nostdinc++
+Do not search for header files in the C++ specific standard
+directories, but do still search the other standard directories.
+(This option is used when building libg++.)
+.TP
+.BI "\-D " "name"\c
+\&
+Predefine \c
+.I name\c
+\& as a macro, with definition `\|\c
+.B 1\c
+\&\|'.
+.TP
+.BI "\-D " "name" = definition
+\&
+Predefine \c
+.I name\c
+\& as a macro, with definition \c
+.I definition\c
+\&.
+There are no restrictions on the contents of \c
+.I definition\c
+\&, but if
+you are invoking the preprocessor from a shell or shell-like program
+you may need to use the shell's quoting syntax to protect characters
+such as spaces that have a meaning in the shell syntax. If you use more than
+one `\|\c
+.B \-D\c
+\&\|' for the same
+.I name\c
+\&, the rightmost definition takes effect.
+.TP
+.BI "\-U " "name"\c
+\&
+Do not predefine \c
+.I name\c
+\&. If both `\|\c
+.B \-U\c
+\&\|' and `\|\c
+.B \-D\c
+\&\|' are
+specified for one name, the `\|\c
+.B \-U\c
+\&\|' beats the `\|\c
+.B \-D\c
+\&\|' and the name
+is not predefined.
+.TP
+.B \-undef
+Do not predefine any nonstandard macros.
+.TP
+.BI "\-A " "name(" value )
+Assert (in the same way as the \c
+.B #assert\c
+\& directive)
+the predicate \c
+.I name\c
+\& with tokenlist \c
+.I value\c
+\&. Remember to escape or quote the parentheses on
+shell command lines.
+
+You can use `\|\c
+.B \-A-\c
+\&\|' to disable all predefined assertions; it also
+undefines all predefined macros.
+.TP
+.B \-dM
+Instead of outputting the result of preprocessing, output a list of
+`\|\c
+.B #define\c
+\&\|' directives for all the macros defined during the
+execution of the preprocessor, including predefined macros. This gives
+you a way of finding out what is predefined in your version of the
+preprocessor; assuming you have no file `\|\c
+.B foo.h\c
+\&\|', the command
+.sp
+.br
+touch\ foo.h;\ cpp\ \-dM\ foo.h
+.br
+.sp
+will show the values of any predefined macros.
+.TP
+.B \-dD
+Like `\|\c
+.B \-dM\c
+\&\|' except in two respects: it does \c
+.I not\c
+\& include the
+predefined macros, and it outputs \c
+.I both\c
+\& the `\|\c
+.B #define\c
+\&\|'
+directives and the result of preprocessing. Both kinds of output go to
+the standard output file.
+.PP
+.TP
+.BR \-M\ [ \-MG ]
+Instead of outputting the result of preprocessing, output a rule
+suitable for \c
+.B make\c
+\& describing the dependencies of the main
+source file. The preprocessor outputs one \c
+.B make\c
+\& rule containing
+the object file name for that source file, a colon, and the names of
+all the included files. If there are many included files then the
+rule is split into several lines using `\|\c
+.B \\\\\c
+\&\|'-newline.
+
+`\|\c
+.B \-MG\c
+\&\|' says to treat missing header files as generated files and assume \c
+they live in the same directory as the source file. It must be specified \c
+in addition to `\|\c
+.B \-M\c
+\&\|'.
+
+This feature is used in automatic updating of makefiles.
+.TP
+.BR \-MM\ [ \-MG ]
+Like `\|\c
+.B \-M\c
+\&\|' but mention only the files included with `\|\c
+.B #include
+"\c
+.I file\c
+\&"\c
+\&\|'. System header files included with `\|\c
+.B #include
+<\c
+.I file\c
+\&>\c
+\&\|' are omitted.
+.TP
+.BI \-MD\ file
+Like `\|\c
+.B \-M\c
+\&\|' but the dependency information is written to `\|\c
+.I file\c
+\&\|'. This is in addition to compiling the file as
+specified\(em\&`\|\c
+.B \-MD\c
+\&\|' does not inhibit ordinary compilation the way
+`\|\c
+.B \-M\c
+\&\|' does.
+
+When invoking gcc, do not specify the `\|\c
+.I file\c
+\&\|' argument. Gcc will create file names made by replacing `\|\c
+.B .c\c
+\&\|' with `\|\c
+.B .d\c
+\&\|' at the end of the input file names.
+
+In Mach, you can use the utility \c
+.B md\c
+\& to merge multiple files
+into a single dependency file suitable for using with the `\|\c
+.B make\c
+\&\|'
+command.
+.TP
+.BI \-MMD\ file
+Like `\|\c
+.B \-MD\c
+\&\|' except mention only user header files, not system
+header files.
+.TP
+.B \-H
+Print the name of each header file used, in addition to other normal
+activities.
+.TP
+.BI "\-imacros " "file"\c
+\&
+Process \c
+.I file\c
+\& as input, discarding the resulting output, before
+processing the regular input file. Because the output generated from
+\c
+.I file\c
+\& is discarded, the only effect of `\|\c
+.B \-imacros \c
+.I file\c
+\&\c
+\&\|' is to
+make the macros defined in \c
+.I file\c
+\& available for use in the main
+input. The preprocessor evaluates any `\|\c
+.B \-D\c
+\&\|' and `\|\c
+.B \-U\c
+\&\|' options
+on the command line before processing `\|\c
+.B \-imacros \c
+.I file\c
+\&\|' \c
+\&.
+.TP
+.BI "\-include " "file"
+Process
+.I file
+as input, and include all the resulting output,
+before processing the regular input file.
+.TP
+.BI "-idirafter " "dir"\c
+\&
+Add the directory \c
+.I dir\c
+\& to the second include path. The directories
+on the second include path are searched when a header file is not found
+in any of the directories in the main include path (the one that
+`\|\c
+.B \-I\c
+\&\|' adds to).
+.TP
+.BI "-iprefix " "prefix"\c
+\&
+Specify \c
+.I prefix\c
+\& as the prefix for subsequent `\|\c
+.B \-iwithprefix\c
+\&\|'
+options.
+.TP
+.BI "-iwithprefix " "dir"\c
+\&
+Add a directory to the second include path. The directory's name is
+made by concatenating \c
+.I prefix\c
+\& and \c
+.I dir\c
+\&, where \c
+.I prefix\c
+\&
+was specified previously with `\|\c
+.B \-iprefix\c
+\&\|'.
+.TP
+.B \-lang-c
+.TP
+.B \-lang-c++
+.TP
+.B \-lang-objc
+.TP
+.B \-lang-objc++
+Specify the source language. `\|\c
+.B \-lang-c++\c
+\&\|' makes the preprocessor
+handle C++ comment syntax, and includes extra default include
+directories for C++, and `\|\c
+.B \-lang-objc\c
+\&\|' enables the Objective C
+`\|\c
+.B #import\c
+\&\|' directive. `\|\c
+.B \-lang-c\c
+\&\|' explicitly turns off both of
+these extensions, and `\|\c
+.B \-lang-objc++\c
+\&\|' enables both.
+
+These options are generated by the compiler driver \c
+.B gcc\c
+\&, but not
+passed from the `\|\c
+.B gcc\c
+\&\|' command line.
+.TP
+.B \-lint
+Look for commands to the program checker \c
+.B lint\c
+\& embedded in
+comments, and emit them preceded by `\|\c
+.B #pragma lint\c
+\&\|'. For example,
+the comment `\|\c
+.B /* NOTREACHED */\c
+\&\|' becomes `\|\c
+.B #pragma lint
+NOTREACHED\c
+\&\|'.
+
+This option is available only when you call \c
+.B cpp\c
+\& directly;
+\c
+.B gcc\c
+\& will not pass it from its command line.
+.TP
+.B \-$
+Forbid the use of `\|\c
+.B $\c
+\&\|' in identifiers. This was formerly required for strict conformance
+to the C Standard before the standard was corrected. \c
+
+This option is available only when you call \c
+.B cpp\c
+\& directly;
+.B gcc\c
+\& will not pass it from its command line.

+.SH NAME
+gcc, g++ \- GNU project C and C++ Compiler (v2.7)
+.SH SYNOPSIS
+.B gcc
+.RI "[ " option " | " filename " ].\|.\|."
+.br
+.B g++
+.RI "[ " option " | " filename " ].\|.\|."
+.SH WARNING
+The information in this man page is an extract from the full
+documentation of the GNU C compiler, and is limited to the meaning of
+the options.
+.PP
+This man page is not kept up to date except when volunteers want to
+maintain it. If you find a discrepancy between the man page and the
+software, please check the Info file, which is the authoritative
+documentation.
+.PP
+If we find that the things in this man page that are out of date cause
+significant confusion or complaints, we will stop distributing the man
+page. The alternative, updating the man page when we update the Info
+file, is impossible because the rest of the work of maintaining GNU CC
+leaves us no time for that. The GNU project regards man pages as
+obsolete and should not let them take time away from other things.
+.PP
+For complete and current documentation, refer to the Info file `\|\c
+.B gcc\c
+\&\|' or the manual
+.I
+Using and Porting GNU CC (for version 2.0)\c
+\&. Both are made from the Texinfo source file
+.BR gcc.texinfo .
+.SH DESCRIPTION
+The C and C++ compilers are integrated. Both process input files
+through one or more of four stages: preprocessing, compilation,
+assembly, and linking. Source filename suffixes identify the source
+language, but which name you use for the compiler governs default
+assumptions:
+.TP
+.B gcc
+assumes preprocessed (\c
+.B .i\c
+\&) files are C and assumes C style linking.
+.TP
+.B g++
+assumes preprocessed (\c
+.B .i\c
+\&) files are C++ and assumes C++ style linking.
+.PP
+Suffixes of source file names indicate the language and kind of
+processing to be done:
+.Sp
+.nf
+.ta \w'\fB.cxx\fP 'u
+\&\fB.c\fP C source; preprocess, compile, assemble
+\&\fB.C\fP C++ source; preprocess, compile, assemble
+\&\fB.cc\fP C++ source; preprocess, compile, assemble
+\&\fB.cxx\fP C++ source; preprocess, compile, assemble
+\&\fB.m\fP Objective-C source; preprocess, compile, assemble
+\&\fB.i\fP preprocessed C; compile, assemble
+\&\fB.ii\fP preprocessed C++; compile, assemble
+\&\fB.s\fP Assembler source; assemble
+\&\fB.S\fP Assembler source; preprocess, assemble
+\&\fB.h\fP Preprocessor file; not usually named on command line
+.Sp
+.fi
+Files with other suffixes are passed to the linker. Common cases include:
+.Sp
+.nf
+\&\fB.o\fP Object file
+\&\fB.a\fP Archive file
+.br
+.fi
+.Sp
+Linking is always the last stage unless you use one of the
+.BR \-c ,
+.BR \-S ,
+or
+.B \-E
+options to avoid it (or unless compilation errors stop the whole
+process). For the link stage, all
+.B .o
+files corresponding to source files,
+.B \-l
+libraries, unrecognized filenames (including named
+.B .o
+object files and
+.B .a
+archives)
+are passed to the linker in command-line order.
+.SH OPTIONS
+Options must be separate: `\|\c
+.B \-dr\c
+\&\|' is quite different from `\|\c
+.B \-d \-r
+\&\|'.
+.PP
+Most `\|\c
+.B \-f\c
+\&\|' and `\|\c
+.B \-W\c
+\&\|' options have two contrary forms:
+.BI \-f name
+and
+.BI \-fno\- name\c
+\& (or
+.BI \-W name
+and
+.BI \-Wno\- name\c
+\&). Only the non-default forms are shown here.
+.PP
+Here is a summary of all the options, grouped by type. Explanations are
+in the following sections.

+.SH OVERALL OPTIONS
+.TP
+.BI "\-x " "language"
+Specify explicitly the
+.I language\c
+\& for the following input files (rather than choosing a default based
+on the file name suffix) . This option applies to all following input
+files until the next `\|\c
+.B \-x\c
+\&\|' option. Possible values of \c
+.I language\c
+\& are
+`\|\c
+.B c\c
+\&\|', `\|\c
+.B objective\-c\c
+\&\|', `\|\c
+.B c\-header\c
+\&\|', `\|\c
+.B c++\c
+\&\|',
+`\|\c
+.B cpp\-output\c
+\&\|', `\|\c
+.B assembler\c
+\&\|', and `\|\c
+.B assembler\-with\-cpp\c
+\&\|'.
+.TP
+.B \-x none
+Turn off any specification of a language, so that subsequent files are
+handled according to their file name suffixes (as they are if `\|\c
+.B \-x\c
+\&\|'
+has not been used at all).
+.PP
+If you want only some of the four stages (preprocess, compile,
+assemble, link), you can use
+`\|\c
+.B \-x\c
+\&\|' (or filename suffixes) to tell \c
+.B gcc\c
+\& where to start, and
+one of the options `\|\c
+.B \-c\c
+\&\|', `\|\c
+.B \-S\c
+\&\|', or `\|\c
+.B \-E\c
+\&\|' to say where
+.B gcc\c
+\& is to stop. Note that some combinations (for example,
+`\|\c
+.B \-x cpp\-output \-E\c
+\&\|') instruct \c
+.B gcc\c
+\& to do nothing at all.
+.TP
+.B \-c
+Compile or assemble the source files, but do not link. The compiler
+output is an object file corresponding to each source file.
+.Sp
+By default, GCC makes the object file name for a source file by replacing
+the suffix `\|\c
+.B .c\c
+\&\|', `\|\c
+.B .i\c
+\&\|', `\|\c
+.B .s\c
+\&\|', etc., with `\|\c
+.B .o\c
+\&\|'. Use
+.B \-o\c
+\& to select another name.
+.Sp
+GCC ignores any unrecognized input files (those that do not require
+compilation or assembly) with the
+.B \-c
+option.
+.TP
+.B \-S
+Stop after the stage of compilation proper; do not assemble. The output
+is an assembler code file for each non-assembler input
+file specified.
+.Sp
+By default, GCC makes the assembler file name for a source file by
+replacing the suffix `\|\c
+.B .c\c
+\&\|', `\|\c
+.B .i\c
+\&\|', etc., with `\|\c
+.B .s\c
+\&\|'. Use
+.B \-o\c
+\& to select another name.
+.Sp
+GCC ignores any input files that don't require compilation.
+.TP
+.B \-E
+Stop after the preprocessing stage; do not run the compiler proper. The
+output is preprocessed source code, which is sent to the
+standard output.
+.Sp
+GCC ignores input files which don't require preprocessing.
+.TP
+.BI "\-o " file
+Place output in file \c
+.I file\c
+\&. This applies regardless to whatever
+sort of output GCC is producing, whether it be an executable file,
+an object file, an assembler file or preprocessed C code.
+.Sp
+Since only one output file can be specified, it does not make sense to
+use `\|\c
+.B \-o\c
+\&\|' when compiling more than one input file, unless you are
+producing an executable file as output.
+.Sp
+If you do not specify `\|\c
+.B \-o\c
+\&\|', the default is to put an executable file
+in `\|\c
+.B a.out\c
+\&\|', the object file for `\|\c
+.I source\c
+.B \&.\c
+.I suffix\c
+\&\c
+\&\|' in
+`\|\c
+.I source\c
+.B \&.o\c
+\&\|', its assembler file in `\|\c
+.I source\c
+.B \&.s\c
+\&\|', and
+all preprocessed C source on standard output.
+.TP
+.B \-v
+Print (on standard error output) the commands executed to run the stages
+of compilation. Also print the version number of the compiler driver
+program and of the preprocessor and the compiler proper.
+.TP
+.B \-pipe
+Use pipes rather than temporary files for communication between the
+various stages of compilation. This fails to work on some systems where
+the assembler cannot read from a pipe; but the GNU assembler has
+no trouble.
+.PP
+.SH LANGUAGE OPTIONS
+The following options control the dialect of C that the compiler
+accepts:
+.TP
+.B \-ansi
+Support all ANSI standard C programs.
+.Sp
+This turns off certain features of GNU C that are incompatible with
+ANSI C, such as the \c
+.B asm\c
+\&, \c
+.B inline\c
+\& and \c
+.B typeof
+keywords, and predefined macros such as \c
+.B unix\c
+\& and \c
+.B vax
+that identify the type of system you are using. It also enables the
+undesirable and rarely used ANSI trigraph feature, and disallows `\|\c
+.B $\c
+\&\|' as part of identifiers.
+.Sp
+The alternate keywords \c
+.B _\|_asm_\|_\c
+\&, \c
+.B _\|_extension_\|_\c
+\&,
+.B _\|_inline_\|_\c
+\& and \c
+.B _\|_typeof_\|_\c
+\& continue to work despite
+`\|\c
+.B \-ansi\c
+\&\|'. You would not want to use them in an ANSI C program, of
+course, but it is useful to put them in header files that might be included
+in compilations done with `\|\c
+.B \-ansi\c
+\&\|'. Alternate predefined macros
+such as \c
+.B _\|_unix_\|_\c
+\& and \c
+.B _\|_vax_\|_\c
+\& are also available, with or
+without `\|\c
+.B \-ansi\c
+\&\|'.
+.Sp
+The `\|\c
+.B \-ansi\c
+\&\|' option does not cause non-ANSI programs to be
+rejected gratuitously. For that, `\|\c
+.B \-pedantic\c
+\&\|' is required in
+addition to `\|\c
+.B \-ansi\c
+\&\|'.
+.Sp
+The preprocessor predefines a macro \c
+.B _\|_STRICT_ANSI_\|_\c
+\& when you use the `\|\c
+.B \-ansi\c
+\&\|'
+option. Some header files may notice this macro and refrain
+from declaring certain functions or defining certain macros that the
+ANSI standard doesn't call for; this is to avoid interfering with any
+programs that might use these names for other things.
+.TP
+.B \-fno\-asm
+Do not recognize \c
+.B asm\c
+\&, \c
+.B inline\c
+\& or \c
+.B typeof\c
+\& as a
+keyword. These words may then be used as identifiers. You can
+use \c
+.B _\|_asm_\|_\c
+\&, \c
+.B _\|_inline_\|_\c
+\& and \c
+.B _\|_typeof_\|_\c
+\& instead.
+`\|\c
+.B \-ansi\c
+\&\|' implies `\|\c
+.B \-fno\-asm\c
+\&\|'.
+.TP
+.B \-fno\-builtin
+Don't recognize built-in functions that do not begin with two leading
+underscores. Currently, the functions affected include \c
+.B _exit\c
+\&,
+.B abort\c
+\&, \c
+.B abs\c
+\&, \c
+.B alloca\c
+\&, \c
+.B cos\c
+\&, \c
+.B exit\c
+\&,
+.B fabs\c
+\&, \c
+.B labs\c
+\&, \c
+.B memcmp\c
+\&, \c
+.B memcpy\c
+\&, \c
+.B sin\c
+\&,
+.B sqrt\c
+\&, \c
+.B strcmp\c
+\&, \c
+.B strcpy\c
+\&, and \c
+.B strlen\c
+\&.
+.Sp
+The `\|\c
+.B \-ansi\c
+\&\|' option prevents \c
+.B alloca\c
+\& and \c
+.B _exit\c
+\& from
+being builtin functions.
+.TP
+.B \-fhosted
+Compile for a hosted environment; this implies the `\|\c
+.B \-fbuiltin\c
+\&\|' option, and implies that suspicious declarations of
+.B main\c
+\& should be warned about.
+.TP
+.B \-ffreestanding
+Compile for a freestanding environment; this implies the `\|\c
+.B \-fno-builtin\c
+\&\|' option, and implies that
+.B main\c
+\& has no special requirements.
+.TP
+.B \-fno\-strict\-prototype
+Treat a function declaration with no arguments, such as `\|\c
+.B int foo
+();\c
+\&\|', as C would treat it\(em\&as saying nothing about the number of
+arguments or their types (C++ only). Normally, such a declaration in
+C++ means that the function \c
+.B foo\c
+\& takes no arguments.
+.TP
+.B \-trigraphs
+Support ANSI C trigraphs. The `\|\c
+.B \-ansi\c
+\&\|' option implies `\|\c
+.B \-trigraphs\c
+\&\|'.
+.TP
+.B \-traditional
+Attempt to support some aspects of traditional C compilers.
+For details, see the GNU C Manual; the duplicate list here
+has been deleted so that we won't get complaints when it
+is out of date.
+.Sp
+But one note about C++ programs only (not C). `\|\c
+.B \-traditional\c
+\&\|' has one additional effect for C++: assignment to
+.B this
+is permitted. This is the same as the effect of `\|\c
+.B \-fthis\-is\-variable\c
+\&\|'.
+.TP
+.B \-traditional\-cpp
+Attempt to support some aspects of traditional C preprocessors.
+This includes the items that specifically mention the preprocessor above,
+but none of the other effects of `\|\c
+.B \-traditional\c
+\&\|'.
+.TP
+.B \-fdollars\-in\-identifiers
+Permit the use of `\|\c
+.B $\c
+\&\|' in identifiers (C++ only). You can also use
+`\|\c
+.B \-fno\-dollars\-in\-identifiers\c
+\&\|' to explicitly prohibit use of
+`\|\c
+.B $\c
+\&\|'. (GNU C++ allows `\|\c
+.B $\c
+\&\|' by default on some target systems
+but not others.)
+.TP
+.B \-fenum\-int\-equiv
+Permit implicit conversion of \c
+.B int\c
+\& to enumeration types (C++
+only). Normally GNU C++ allows conversion of \c
+.B enum\c
+\& to \c
+.B int\c
+\&,
+but not the other way around.
+.TP
+.B \-fexternal\-templates
+Produce smaller code for template declarations, by generating only a
+single copy of each template function where it is defined (C++ only).
+To use this option successfully, you must also mark all files that
+use templates with either `\|\c
+.B #pragma implementation\c
+\&\|' (the definition) or
+`\|\c
+.B #pragma interface\c
+\&\|' (declarations).
+
+When your code is compiled with `\|\c
+.B \-fexternal\-templates\c
+\&\|', all
+template instantiations are external. You must arrange for all
+necessary instantiations to appear in the implementation file; you can
+do this with a \c
+.B typedef\c
+\& that references each instantiation needed.
+Conversely, when you compile using the default option
+`\|\c
+.B \-fno\-external\-templates\c
+\&\|', all template instantiations are
+explicitly internal.
+.TP
+.B \-fall\-virtual
+Treat all possible member functions as virtual, implicitly. All
+member functions (except for constructor functions and
+.B new
+or
+.B delete
+member operators) are treated as virtual functions of the class where
+they appear.
+.Sp
+This does not mean that all calls to these member functions will be
+made through the internal table of virtual functions. Under some
+circumstances, the compiler can determine that a call to a given
+virtual function can be made directly; in these cases the calls are
+direct in any case.
+.TP
+.B \-fcond\-mismatch
+Allow conditional expressions with mismatched types in the second and
+third arguments. The value of such an expression is void.
+.TP
+.B \-fthis\-is\-variable
+Permit assignment to \c
+.B this\c
+\& (C++ only). The incorporation of
+user-defined free store management into C++ has made assignment to
+`\|\c
+.B this\c
+\&\|' an anachronism. Therefore, by default it is invalid to
+assign to \c
+.B this\c
+\& within a class member function. However, for
+backwards compatibility, you can make it valid with
+`\|\c
+.B \-fthis-is-variable\c
+\&\|'.
+.TP
+.B \-funsigned\-char
+Let the type \c
+.B char\c
+\& be unsigned, like \c
+.B unsigned char\c
+\&.
+.Sp
+Each kind of machine has a default for what \c
+.B char\c
+\& should
+be. It is either like \c
+.B unsigned char\c
+\& by default or like
+.B signed char\c
+\& by default.
+.Sp
+Ideally, a portable program should always use \c
+.B signed char\c
+\& or
+.B unsigned char\c
+\& when it depends on the signedness of an object.
+But many programs have been written to use plain \c
+.B char\c
+\& and
+expect it to be signed, or expect it to be unsigned, depending on the
+machines they were written for. This option, and its inverse, let you
+make such a program work with the opposite default.
+.Sp
+The type \c
+.B char\c
+\& is always a distinct type from each of
+.B signed char\c
+\& and \c
+.B unsigned char\c
+\&, even though its behavior
+is always just like one of those two.
+.TP
+.B \-fsigned\-char
+Let the type \c
+.B char\c
+\& be signed, like \c
+.B signed char\c
+\&.
+.Sp
+Note that this is equivalent to `\|\c
+.B \-fno\-unsigned\-char\c
+\&\|', which is
+the negative form of `\|\c
+.B \-funsigned\-char\c
+\&\|'. Likewise,
+`\|\c
+.B \-fno\-signed\-char\c
+\&\|' is equivalent to `\|\c
+.B \-funsigned\-char\c
+\&\|'.
+.TP
+.B \-fsigned\-bitfields
+.TP
+.B \-funsigned\-bitfields
+.TP
+.B \-fno\-signed\-bitfields
+.TP
+.B \-fno\-unsigned\-bitfields
+These options control whether a bitfield is
+signed or unsigned, when declared with no explicit `\|\c
+.B signed\c
+\&\|' or `\|\c
+.B unsigned\c
+\&\|' qualifier. By default, such a bitfield is
+signed, because this is consistent: the basic integer types such as
+.B int\c
+\& are signed types.
+.Sp
+However, when you specify `\|\c
+.B \-traditional\c
+\&\|', bitfields are all unsigned
+no matter what.
+.TP
+.B \-fwritable\-strings
+Store string constants in the writable data segment and don't uniquize
+them. This is for compatibility with old programs which assume they
+can write into string constants. `\|\c
+.B \-traditional\c
+\&\|' also has this
+effect.
+.Sp
+Writing into string constants is a very bad idea; \*(lqconstants\*(rq should
+be constant.
+.SH PREPROCESSOR OPTIONS
+These options control the C preprocessor, which is run on each C source
+file before actual compilation.
+.PP
+If you use the `\|\c
+.B \-E\c
+\&\|' option, GCC does nothing except preprocessing.
+Some of these options make sense only together with `\|\c
+.B \-E\c
+\&\|' because
+they cause the preprocessor output to be unsuitable for actual
+compilation.
+.TP
+.BI "\-include " "file"
+Process \c
+.I file\c
+\& as input before processing the regular input file.
+In effect, the contents of \c
+.I file\c
+\& are compiled first. Any `\|\c
+.B \-D\c
+\&\|'
+and `\|\c
+.B \-U\c
+\&\|' options on the command line are always processed before
+`\|\c
+.B \-include \c
+.I file\c
+\&\c
+\&\|', regardless of the order in which they are
+written. All the `\|\c
+.B \-include\c
+\&\|' and `\|\c
+.B \-imacros\c
+\&\|' options are
+processed in the order in which they are written.
+.TP
+.BI "\-imacros " file
+Process \c
+.I file\c
+\& as input, discarding the resulting output, before
+processing the regular input file. Because the output generated from
+.I file\c
+\& is discarded, the only effect of `\|\c
+.B \-imacros \c
+.I file\c
+\&\c
+\&\|' is to
+make the macros defined in \c
+.I file\c
+\& available for use in the main
+input. The preprocessor evaluates any `\|\c
+.B \-D\c
+\&\|' and `\|\c
+.B \-U\c
+\&\|' options
+on the command line before processing `\|\c
+.B \-imacros\c
+.I file\c
+\&\|', regardless of the order in
+which they are written. All the `\|\c
+.B \-include\c
+\&\|' and `\|\c
+.B \-imacros\c
+\&\|'
+options are processed in the order in which they are written.
+.TP
+.BI "\-idirafter " "dir"
+Add the directory \c
+.I dir\c
+\& to the second include path. The directories
+on the second include path are searched when a header file is not found
+in any of the directories in the main include path (the one that
+`\|\c
+.B \-I\c
+\&\|' adds to).
+.TP
+.BI "\-iprefix " "prefix"
+Specify \c
+.I prefix\c
+\& as the prefix for subsequent `\|\c
+.B \-iwithprefix\c
+\&\|'
+options.
+.TP
+.BI "\-iwithprefix " "dir"
+Add a directory to the second include path. The directory's name is
+made by concatenating \c
+.I prefix\c
+\& and \c
+.I dir\c
+\&, where \c
+.I prefix
+was specified previously with `\|\c
+.B \-iprefix\c
+\&\|'.
+.TP
+.B \-nostdinc
+Do not search the standard system directories for header files. Only
+the directories you have specified with `\|\c
+.B \-I\c
+\&\|' options (and the
+current directory, if appropriate) are searched.
+.Sp
+By using both `\|\c
+.B \-nostdinc\c
+\&\|' and `\|\c
+.B \-I\-\c
+\&\|', you can limit the include-file search file to only those
+directories you specify explicitly.
+.TP
+.B \-nostdinc++
+Do not search for header files in the C++\-specific standard directories,
+but do still search the other standard directories.
+(This option is used when building `\|\c
+.B libg++\c
+\&\|'.)
+.TP
+.B \-undef
+Do not predefine any nonstandard macros. (Including architecture flags).
+.TP
+.B \-E
+Run only the C preprocessor. Preprocess all the C source files
+specified and output the results to standard output or to the
+specified output file.
+.TP
+.B \-C
+Tell the preprocessor not to discard comments. Used with the
+`\|\c
+.B \-E\c
+\&\|' option.
+.TP
+.B \-P
+Tell the preprocessor not to generate `\|\c
+.B #line\c
+\&\|' commands.
+Used with the `\|\c
+.B \-E\c
+\&\|' option.
+.TP
+.B \-M\ [ \-MG ]
+Tell the preprocessor to output a rule suitable for \c
+.B make
+describing the dependencies of each object file. For each source file,
+the preprocessor outputs one \c
+.B make\c
+\&-rule whose target is the object
+file name for that source file and whose dependencies are all the files
+`\|\c
+.B #include\c
+\&\|'d in it. This rule may be a single line or may be
+continued with `\|\c
+.B \e\c
+\&\|'-newline if it is long. The list of rules is
+printed on standard output instead of the preprocessed C program.
+.Sp
+`\|\c
+.B \-M\c
+\&\|' implies `\|\c
+.B \-E\c
+\&\|'.
+.Sp
+`\|\c
+.B \-MG\c
+\&\|' says to treat missing header files as generated files and assume \c
+they live in the same directory as the source file. It must be specified \c
+in addition to `\|\c
+.B \-M\c
+\&\|'.
+.TP
+.B \-MM\ [ \-MG ]
+Like `\|\c

+.BI \-D macro
+Define macro \c

+\&\|' as its definition.
+.TP
+.BI \-D macro = defn
+Define macro \c

+Only `\|\c

+.SH ASSEMBLER OPTION
+.TP
+.BI "\-Wa," "option"
+Pass \c
+.I option\c
+\& as an option to the assembler. If \c
+.I option
+contains commas, it is split into multiple options at the commas.
+.SH LINKER OPTIONS
+These options come into play when the compiler links object files into
+an executable output file. They are meaningless if the compiler is
+not doing a link step.
+.TP
+.I object-file-name
+A file name that does not end in a special recognized suffix is
+considered to name an object file or library. (Object files are
+distinguished from libraries by the linker according to the file
+contents.) If GCC does a link step, these object files are used as input
+to the linker.
+.TP
+.BI \-l library
+Use the library named \c
+.I library\c
+\& when linking.
+.Sp
+The linker searches a standard list of directories for the library,
+which is actually a file named `\|\c
+.B lib\c
+.I library\c
+\&.a\c
+\&\|'. The linker
+then uses this file as if it had been specified precisely by name.
+.Sp
+The directories searched include several standard system directories
+plus any that you specify with `\|\c
+.B \-L\c
+\&\|'.
+.Sp
+Normally the files found this way are library files\(em\&archive files
+whose members are object files. The linker handles an archive file by
+scanning through it for members which define symbols that have so far
+been referenced but not defined. However, if the linker finds an
+ordinary object file rather than a library, the object file is linked
+in the usual fashion. The only difference between using an `\|\c
+.B \-l\c
+\&\|' option and specifying a file
+name is that `\|\c
+.B \-l\c
+\&\|' surrounds
+.I library
+with `\|\c
+.B lib\c
+\&\|' and `\|\c
+.B .a\c
+\&\|' and searches several directories.
+.TP
+.B \-lobjc
+You need this special case of the
+.B \-l
+option in order to link an Objective C program.
+.TP
+.B \-nostartfiles
+Do not use the standard system startup files when linking.
+The standard libraries are used normally.
+.TP
+.B \-nostdlib
+Don't use the standard system libraries and startup files when linking.
+Only the files you specify will be passed to the linker.
+.TP
+.B \-static
+On systems that support dynamic linking, this prevents linking with the shared
+libraries. On other systems, this option has no effect.
+.TP
+.B \-shared
+Produce a shared object which can then be linked with other objects to
+form an executable. Only a few systems support this option.
+.TP
+.B \-symbolic
+Bind references to global symbols when building a shared object. Warn
+about any unresolved references (unless overridden by the link editor
+option `\|\c
+.B
+\-Xlinker \-z \-Xlinker defs\c
+\&\|'). Only a few systems support
+this option.
+.TP
+.BI "\-Xlinker " "option"
+Pass \c
+.I option
+as an option to the linker. You can use this to
+supply system-specific linker options which GNU CC does not know how to
+recognize.
+.Sp
+If you want to pass an option that takes an argument, you must use
+`\|\c
+.B \-Xlinker\c
+\&\|' twice, once for the option and once for the argument.
+For example, to pass `\|\c
+.B
+\-assert definitions\c
+\&\|', you must write
+`\|\c
+.B
+\-Xlinker \-assert \-Xlinker definitions\c
+\&\|'. It does not work to write
+`\|\c
+.B
+\-Xlinker "\-assert definitions"\c
+\&\|', because this passes the entire
+string as a single argument, which is not what the linker expects.
+.TP
+.BI "\-Wl," "option"
+Pass \c
+.I option\c
+\& as an option to the linker. If \c
+.I option\c
+\& contains
+commas, it is split into multiple options at the commas.
+.TP
+.BI "\-u " "symbol"
+Pretend the symbol
+.I symbol
+is undefined, to force linking of
+library modules to define it. You can use `\|\c
+.B \-u\c
+\&\|' multiple times with
+different symbols to force loading of additional library modules.
+.SH DIRECTORY OPTIONS
+These options specify directories to search for header files, for
+libraries and for parts of the compiler:
+.TP
+.BI "\-I" "dir"
+Append directory \c
+.I dir\c
+\& to the list of directories searched for include files.
+.TP
+.B \-I\-
+Any directories you specify with `\|\c
+.B \-I\c
+\&\|' options before the `\|\c
+.B \-I\-\c
+\&\|'
+option are searched only for the case of `\|\c
+.B
+#include "\c
+.I file\c
+.B
+\&"\c
+\&\|';
+they are not searched for `\|\c
+.B #include <\c
+.I file\c
+\&>\c
+\&\|'.
+.Sp
+If additional directories are specified with `\|\c
+.B \-I\c
+\&\|' options after
+the `\|\c
+.B \-I\-\c
+\&\|', these directories are searched for all `\|\c
+.B #include\c
+\&\|'
+directives. (Ordinarily \c
+.I all\c
+\& `\|\c
+.B \-I\c
+\&\|' directories are used
+this way.)
+.Sp
+In addition, the `\|\c
+.B \-I\-\c
+\&\|' option inhibits the use of the current
+directory (where the current input file came from) as the first search
+directory for `\|\c
+.B
+#include "\c
+.I file\c
+.B
+\&"\c
+\&\|'. There is no way to
+override this effect of `\|\c
+.B \-I\-\c
+\&\|'. With `\|\c
+.B \-I.\c
+\&\|' you can specify
+searching the directory which was current when the compiler was
+invoked. That is not exactly the same as what the preprocessor does
+by default, but it is often satisfactory.
+.Sp
+`\|\c
+.B \-I\-\c
+\&\|' does not inhibit the use of the standard system directories
+for header files. Thus, `\|\c
+.B \-I\-\c
+\&\|' and `\|\c
+.B \-nostdinc\c
+\&\|' are
+independent.
+.TP
+.BI "\-L" "dir"
+Add directory \c
+.I dir\c
+\& to the list of directories to be searched
+for `\|\c
+.B \-l\c
+\&\|'.
+.TP
+.BI "\-B" "prefix"
+This option specifies where to find the executables, libraries and
+data files of the compiler itself.
+.Sp
+The compiler driver program runs one or more of the subprograms
+`\|\c
+.B cpp\c
+\&\|', `\|\c
+.B cc1\c
+\&\|' (or, for C++, `\|\c
+.B cc1plus\c
+\&\|'), `\|\c
+.B as\c
+\&\|' and `\|\c
+.B ld\c
+\&\|'. It tries
+.I prefix\c
+\& as a prefix for each program it tries to run, both with and
+without `\|\c
+.I machine\c
+.B /\c
+.I version\c
+.B /\c
+\&\|'.
+.Sp
+For each subprogram to be run, the compiler driver first tries the
+`\|\c
+.B \-B\c
+\&\|' prefix, if any. If that name is not found, or if `\|\c
+.B \-B\c
+\&\|'
+was not specified, the driver tries two standard prefixes, which are
+`\|\c
+.B /usr/lib/gcc/\c
+\&\|' and `\|\c
+.B /usr/local/lib/gcc-lib/\c
+\&\|'. If neither of
+those results in a file name that is found, the compiler driver
+searches for the unmodified program
+name, using the directories specified in your
+`\|\c
+.B PATH\c
+\&\|' environment variable.
+.Sp
+The run-time support file `\|\c
+.B libgcc.a\c
+\&\|' is also searched for using the
+`\|\c
+.B \-B\c
+\&\|' prefix, if needed. If it is not found there, the two
+standard prefixes above are tried, and that is all. The file is left
+out of the link if it is not found by those means. Most of the time,
+on most machines, `\|\c
+.B libgcc.a\c
+\&\|' is not actually necessary.
+.Sp
+You can get a similar result from the environment variable
+.B GCC_EXEC_PREFIX\c
+\&; if it is defined, its value is used as a prefix
+in the same way. If both the `\|\c
+.B \-B\c
+\&\|' option and the
+.B GCC_EXEC_PREFIX\c
+\& variable are present, the `\|\c
+.B \-B\c
+\&\|' option is
+used first and the environment variable value second.
+.SH WARNING OPTIONS
+Warnings are diagnostic messages that report constructions which
+are not inherently erroneous but which are risky or suggest there
+may have been an error.
+.Sp
+These options control the amount and kinds of warnings produced by GNU
+CC:
+.TP
+.B \-fsyntax\-only
+Check the code for syntax errors, but don't emit any output.
+.TP
+.B \-w
+Inhibit all warning messages.
+.TP
+.B \-Wno\-import
+Inhibit warning messages about the use of
+.BR #import .
+.TP
+.B \-pedantic
+Issue all the warnings demanded by strict ANSI standard C; reject
+all programs that use forbidden extensions.
+.Sp
+Valid ANSI standard C programs should compile properly with or without
+this option (though a rare few will require `\|\c
+.B \-ansi\c
+\&\|'). However,
+without this option, certain GNU extensions and traditional C features
+are supported as well. With this option, they are rejected. There is
+no reason to \c
+.I use\c
+\& this option; it exists only to satisfy pedants.
+.Sp
+`\|\c
+.B \-pedantic\c
+\&\|' does not cause warning messages for use of the
+alternate keywords whose names begin and end with `\|\c
+.B _\|_\c
+\&\|'. Pedantic
+warnings are also disabled in the expression that follows
+.B _\|_extension_\|_\c
+\&. However, only system header files should use
+these escape routes; application programs should avoid them.
+.TP
+.B \-pedantic\-errors
+Like `\|\c
+.B \-pedantic\c
+\&\|', except that errors are produced rather than
+warnings.
+.TP
+.B \-W
+Print extra warning messages for these events:
+.TP
+\ \ \ \(bu
+A nonvolatile automatic variable might be changed by a call to
+.B longjmp\c
+\&. These warnings are possible only in
+optimizing compilation.
+.Sp
+The compiler sees only the calls to \c
+.B setjmp\c
+\&. It cannot know
+where \c
+.B longjmp\c
+\& will be called; in fact, a signal handler could
+call it at any point in the code. As a result, you may get a warning
+even when there is in fact no problem because \c
+.B longjmp\c
+\& cannot
+in fact be called at the place which would cause a problem.
+.TP
+\ \ \ \(bu
+A function can return either with or without a value. (Falling
+off the end of the function body is considered returning without
+a value.) For example, this function would evoke such a
+warning:
+.Sp
+.nf
+foo (a)
+{
+ if (a > 0)
+ return a;
+}
+.Sp
+.fi
+Spurious warnings can occur because GNU CC does not realize that
+certain functions (including \c
+.B abort\c
+\& and \c
+.B longjmp\c
+\&)
+will never return.
+.TP
+\ \ \ \(bu
+An expression-statement or the left-hand side of a comma expression
+contains no side effects.
+To suppress the warning, cast the unused expression to void.
+For example, an expression such as `\|\c
+.B x[i,j]\c
+\&\|' will cause a warning,
+but `\|\c
+.B x[(void)i,j]\c
+\&\|' will not.
+.TP
+\ \ \ \(bu
+An unsigned value is compared against zero with `\|\c
+.B >\c
+\&\|' or `\|\c
+.B <=\c
+\&\|'.
+.PP
+.TP
+.B \-Wimplicit
+Warn whenever a function or parameter is implicitly declared.
+.TP
+.B \-Wmain
+Warn if the
+.B main
+function is declared or defined with a suspicious type.
+Typically, it is a function with external linkage, returning
+.B int\c
+\&, and
+taking zero or two arguments.
+
+.TP
+.B \-Wreturn\-type
+Warn whenever a function is defined with a return-type that defaults
+to \c
+.B int\c
+\&. Also warn about any \c
+.B return\c
+\& statement with no
+return-value in a function whose return-type is not \c
+.B void\c
+\&.
+.TP
+.B \-Wunused
+Warn whenever a local variable is unused aside from its declaration,
+whenever a function is declared static but never defined, and whenever
+a statement computes a result that is explicitly not used.
+.TP
+.B \-Wswitch
+Warn whenever a \c
+.B switch\c
+\& statement has an index of enumeral type
+and lacks a \c
+.B case\c
+\& for one or more of the named codes of that
+enumeration. (The presence of a \c
+.B default\c
+\& label prevents this
+warning.) \c
+.B case\c
+\& labels outside the enumeration range also
+provoke warnings when this option is used.
+.TP
+.B \-Wcomment
+Warn whenever a comment-start sequence `\|\c
+.B /\(**\c
+\&\|' appears in a comment.
+.TP
+.B \-Wtrigraphs
+Warn if any trigraphs are encountered (assuming they are enabled).
+.TP
+.B \-Wformat
+Check calls to \c
+.B printf\c
+\& and \c
+.B scanf\c
+\&, etc., to make sure that
+the arguments supplied have types appropriate to the format string
+specified.
+.TP
+.B \-Wchar\-subscripts
+Warn if an array subscript has type
+.BR char .
+This is a common cause of error, as programmers often forget that this
+type is signed on some machines.
+.TP
+.B \-Wuninitialized
+An automatic variable is used without first being initialized.
+.Sp
+These warnings are possible only in optimizing compilation,
+because they require data flow information that is computed only
+when optimizing. If you don't specify `\|\c
+.B \-O\c
+\&\|', you simply won't
+get these warnings.
+.Sp
+These warnings occur only for variables that are candidates for
+register allocation. Therefore, they do not occur for a variable that
+is declared \c
+.B volatile\c
+\&, or whose address is taken, or whose size
+is other than 1, 2, 4 or 8 bytes. Also, they do not occur for
+structures, unions or arrays, even when they are in registers.
+.Sp
+Note that there may be no warning about a variable that is used only
+to compute a value that itself is never used, because such
+computations may be deleted by data flow analysis before the warnings
+are printed.
+.Sp
+These warnings are made optional because GNU CC is not smart
+enough to see all the reasons why the code might be correct
+despite appearing to have an error. Here is one example of how
+this can happen:
+.Sp
+.nf
+{
+ int x;
+ switch (y)
+ {
+ case 1: x = 1;
+ break;
+ case 2: x = 4;
+ break;
+ case 3: x = 5;
+ }
+ foo (x);
+}
+.Sp
+.fi
+If the value of \c
+.B y\c
+\& is always 1, 2 or 3, then \c
+.B x\c
+\& is
+always initialized, but GNU CC doesn't know this. Here is
+another common case:
+.Sp
+.nf
+{
+ int save_y;
+ if (change_y) save_y = y, y = new_y;
+ .\|.\|.
+ if (change_y) y = save_y;
+}
+.Sp
+.fi
+This has no bug because \c
+.B save_y\c
+\& is used only if it is set.
+.Sp
+Some spurious warnings can be avoided if you declare as
+.B volatile\c
+\& all the functions you use that never return.
+.TP
+.B \-Wparentheses
+Warn if parentheses are omitted in certain contexts.
+.TP
+.B \-Wtemplate\-debugging
+When using templates in a C++ program, warn if debugging is not yet
+fully available (C++ only).
+.TP
+.B \-Wall
+All of the above `\|\c
+.B \-W\c
+\&\|' options combined. These are all the
+options which pertain to usage that we recommend avoiding and that we
+believe is easy to avoid, even in conjunction with macros.
+.PP
+The remaining `\|\c
+.B \-W.\|.\|.\c
+\&\|' options are not implied by `\|\c
+.B \-Wall\c
+\&\|'
+because they warn about constructions that we consider reasonable to
+use, on occasion, in clean programs.
+.TP
+.B \-Wtraditional
+Warn about certain constructs that behave differently in traditional and
+ANSI C.
+.TP
+\ \ \ \(bu
+Macro arguments occurring within string constants in the macro body.
+These would substitute the argument in traditional C, but are part of
+the constant in ANSI C.
+.TP
+\ \ \ \(bu
+A function declared external in one block and then used after the end of
+the block.
+.TP
+\ \ \ \(bu
+A \c
+.B switch\c
+\& statement has an operand of type \c
+.B long\c
+\&.
+.PP
+.TP
+.B \-Wshadow
+Warn whenever a local variable shadows another local variable.
+.TP
+.BI "\-Wid\-clash\-" "len"
+Warn whenever two distinct identifiers match in the first \c
+.I len
+characters. This may help you prepare a program that will compile
+with certain obsolete, brain-damaged compilers.
+.TP
+.B \-Wpointer\-arith
+Warn about anything that depends on the \*(lqsize of\*(rq a function type or
+of \c
+.B void\c
+\&. GNU C assigns these types a size of 1, for
+convenience in calculations with \c
+.B void \(**\c
+\& pointers and pointers
+to functions.
+.TP
+.B \-Wcast\-qual
+Warn whenever a pointer is cast so as to remove a type qualifier from
+the target type. For example, warn if a \c
+.B const char \(**\c
+\& is cast
+to an ordinary \c
+.B char \(**\c
+\&.
+.TP
+.B \-Wcast\-align
+Warn whenever a pointer is cast such that the required alignment of the
+target is increased. For example, warn if a \c
+.B char \(**\c
+\& is cast to
+an \c
+.B int \(**\c
+\& on machines where integers can only be accessed at
+two- or four-byte boundaries.
+.TP
+.B \-Wwrite\-strings
+Give string constants the type \c
+.B const char[\c
+.I length\c
+.B ]\c
+\& so that
+copying the address of one into a non-\c
+.B const\c
+\& \c
+.B char \(**
+pointer will get a warning. These warnings will help you find at
+compile time code that can try to write into a string constant, but
+only if you have been very careful about using \c
+.B const\c
+\& in
+declarations and prototypes. Otherwise, it will just be a nuisance;
+this is why we did not make `\|\c
+.B \-Wall\c
+\&\|' request these warnings.
+.TP
+.B \-Wconversion
+Warn if a prototype causes a type conversion that is different from what
+would happen to the same argument in the absence of a prototype. This
+includes conversions of fixed point to floating and vice versa, and
+conversions changing the width or signedness of a fixed point argument
+except when the same as the default promotion.
+.TP
+.B \-Waggregate\-return
+Warn if any functions that return structures or unions are defined or
+called. (In languages where you can return an array, this also elicits
+a warning.)
+.TP
+.B \-Wstrict\-prototypes
+Warn if a function is declared or defined without specifying the
+argument types. (An old-style function definition is permitted without
+a warning if preceded by a declaration which specifies the argument
+types.)
+.TP
+.B \-Wmissing\-prototypes
+Warn if a global function is defined without a previous prototype
+declaration. This warning is issued even if the definition itself
+provides a prototype. The aim is to detect global functions that fail
+to be declared in header files.
+.TP
+.B \-Wmissing\-declarations
+Warn if a global function is defined without a previous declaration.
+Do so even if the definition itself provides a prototype.
+Use this option to detect global functions that are not declared in
+header files.
+.TP
+.B \-Wredundant-decls
+Warn if anything is declared more than once in the same scope, even in
+cases where multiple declaration is valid and changes nothing.
+.TP
+.B \-Wnested-externs
+Warn if an \c
+.B extern\c
+\& declaration is encountered within an function.
+.TP
+.B \-Wenum\-clash
+Warn about conversion between different enumeration types (C++ only).
+.TP
+.B \-Woverloaded\-virtual
+(C++ only.)
+In a derived class, the definitions of virtual functions must match
+the type signature of a virtual function declared in the base class.
+Use this option to request warnings when a derived class declares a
+function that may be an erroneous attempt to define a virtual
+function: that is, warn when a function with the same name as a
+virtual function in the base class, but with a type signature that
+doesn't match any virtual functions from the base class.
+.TP
+.B \-Winline
+Warn if a function can not be inlined, and either it was declared as inline,
+or else the
+.B \-finline\-functions
+option was given.
+.TP
+.B \-Werror
+Treat warnings as errors; abort compilation after any warning.
+.SH DEBUGGING OPTIONS
+GNU CC has various special options that are used for debugging
+either your program or GCC:
+.TP
+.B \-g
+Produce debugging information in the operating system's native format
+(stabs, COFF, XCOFF, or DWARF). GDB can work with this debugging
+information.
+.Sp
+On most systems that use stabs format, `\|\c
+.B \-g\c
+\&\|' enables use of extra
+debugging information that only GDB can use; this extra information
+makes debugging work better in GDB but will probably make other debuggers
+crash or
+refuse to read the program. If you want to control for certain whether
+to generate the extra information, use `\|\c
+.B \-gstabs+\c
+\&\|', `\|\c
+.B \-gstabs\c
+\&\|',
+`\|\c
+.B \-gxcoff+\c
+\&\|', `\|\c
+.B \-gxcoff\c
+\&\|', `\|\c
+.B \-gdwarf+\c
+\&\|', or `\|\c
+.B \-gdwarf\c
+\&\|'
+(see below).
+.Sp
+Unlike most other C compilers, GNU CC allows you to use `\|\c
+.B \-g\c
+\&\|' with
+`\|\c
+.B \-O\c
+\&\|'. The shortcuts taken by optimized code may occasionally
+produce surprising results: some variables you declared may not exist
+at all; flow of control may briefly move where you did not expect it;
+some statements may not be executed because they compute constant
+results or their values were already at hand; some statements may
+execute in different places because they were moved out of loops.
+.Sp
+Nevertheless it proves possible to debug optimized output. This makes
+it reasonable to use the optimizer for programs that might have bugs.
+.PP
+The following options are useful when GNU CC is generated with the
+capability for more than one debugging format.
+.TP
+.B \-ggdb
+Produce debugging information in the native format (if that is supported),
+including GDB extensions if at all possible.

+.SH OPTIMIZATION OPTIONS
+These options control various sorts of optimizations:
+.TP
+.B \-O
+.TP
+.B \-O1
+Optimize. Optimizing compilation takes somewhat more time, and a lot
+more memory for a large function.
+.Sp
+Without `\|\c
+.B \-O\c
+\&\|', the compiler's goal is to reduce the cost of
+compilation and to make debugging produce the expected results.
+Statements are independent: if you stop the program with a breakpoint
+between statements, you can then assign a new value to any variable or
+change the program counter to any other statement in the function and
+get exactly the results you would expect from the source code.
+.Sp
+Without `\|\c
+.B \-O\c
+\&\|', only variables declared \c
+.B register\c
+\& are
+allocated in registers. The resulting compiled code is a little worse
+than produced by PCC without `\|\c
+.B \-O\c
+\&\|'.
+.Sp
+With `\|\c
+.B \-O\c
+\&\|', the compiler tries to reduce code size and execution
+time.
+.Sp
+When you specify `\|\c
+.B \-O\c
+\&\|', the two options `\|\c
+.B \-fthread\-jumps\c
+\&\|' and `\|\c
+.B \-fdefer\-pop\c
+\&\|' are turned on. On machines that have delay slots, the `\|\c
+.B \-fdelayed\-branch\c
+\&\|' option is turned on. For those machines that can support debugging even
+without a frame pointer, the `\|\c
+.B \-fomit\-frame\-pointer\c
+\&\|' option is turned on. On some machines other flags may also be turned on.
+.TP
+.B \-O2
+Optimize even more. Nearly all supported optimizations that do not
+involve a space-speed tradeoff are performed. Loop unrolling and function
+inlining are not done, for example. As compared to
+.B \-O\c
+\&,
+this option increases both compilation time and the performance of the
+generated code.
+.TP
+.B \-O3
+Optimize yet more. This turns on everything
+.B \-O2
+does, along with also turning on
+.B \-finline\-functions.
+.TP
+.B \-O0
+Do not optimize.
+.Sp
+If you use multiple
+.B \-O
+options, with or without level numbers, the last such option is the
+one that is effective.
+.PP
+Options of the form `\|\c
+.B \-f\c
+.I flag\c
+\&\c
+\&\|' specify machine-independent
+flags. Most flags have both positive and negative forms; the negative
+form of `\|\c
+.B \-ffoo\c
+\&\|' would be `\|\c
+.B \-fno\-foo\c
+\&\|'. The following list shows
+only one form\(em\&the one which is not the default.
+You can figure out the other form by either removing `\|\c
+.B no\-\c
+\&\|' or
+adding it.
+.TP
+.B \-ffloat\-store
+Do not store floating point variables in registers. This
+prevents undesirable excess precision on machines such as the
+68000 where the floating registers (of the 68881) keep more
+precision than a \c
+.B double\c
+\& is supposed to have.
+.Sp
+For most programs, the excess precision does only good, but a few
+programs rely on the precise definition of IEEE floating point.
+Use `\|\c
+.B \-ffloat\-store\c
+\&\|' for such programs.
+.TP
+.B \-fmemoize\-lookups
+.TP
+.B \-fsave\-memoized
+Use heuristics to compile faster (C++ only). These heuristics are not
+enabled by default, since they are only effective for certain input
+files. Other input files compile more slowly.
+.Sp
+The first time the compiler must build a call to a member function (or
+reference to a data member), it must (1) determine whether the class
+implements member functions of that name; (2) resolve which member
+function to call (which involves figuring out what sorts of type
+conversions need to be made); and (3) check the visibility of the member
+function to the caller. All of this adds up to slower compilation.
+Normally, the second time a call is made to that member function (or
+reference to that data member), it must go through the same lengthy
+process again. This means that code like this
+.Sp
+\& cout << "This " << p << " has " << n << " legs.\en";
+.Sp
+makes six passes through all three steps. By using a software cache,
+a \*(lqhit\*(rq significantly reduces this cost. Unfortunately, using the
+cache introduces another layer of mechanisms which must be implemented,
+and so incurs its own overhead. `\|\c
+.B \-fmemoize\-lookups\c
+\&\|' enables
+the software cache.
+.Sp
+Because access privileges (visibility) to members and member functions
+may differ from one function context to the next,
+.B g++
+may need to flush the cache. With the `\|\c
+.B \-fmemoize\-lookups\c
+\&\|' flag, the cache is flushed after every
+function that is compiled. The `\|\c
+\-fsave\-memoized\c
+\&\|' flag enables the same software cache, but when the compiler
+determines that the context of the last function compiled would yield
+the same access privileges of the next function to compile, it
+preserves the cache.
+This is most helpful when defining many member functions for the same
+class: with the exception of member functions which are friends of
+other classes, each member function has exactly the same access
+privileges as every other, and the cache need not be flushed.
+.TP
+.B \-fno\-default\-inline
+Don't make member functions inline by default merely because they are
+defined inside the class scope (C++ only).
+.TP
+.B \-fno\-defer\-pop
+Always pop the arguments to each function call as soon as that
+function returns. For machines which must pop arguments after a
+function call, the compiler normally lets arguments accumulate on the
+stack for several function calls and pops them all at once.
+.TP
+.B \-fforce\-mem
+Force memory operands to be copied into registers before doing
+arithmetic on them. This may produce better code by making all
+memory references potential common subexpressions. When they are
+not common subexpressions, instruction combination should
+eliminate the separate register-load. I am interested in hearing
+about the difference this makes.
+.TP
+.B \-fforce\-addr
+Force memory address constants to be copied into registers before
+doing arithmetic on them. This may produce better code just as
+`\|\c
+.B \-fforce\-mem\c
+\&\|' may. I am interested in hearing about the
+difference this makes.
+.TP
+.B \-fomit\-frame\-pointer
+Don't keep the frame pointer in a register for functions that
+don't need one. This avoids the instructions to save, set up and
+restore frame pointers; it also makes an extra register available
+in many functions. \c
+.I It also makes debugging impossible on most machines\c
+\&.
+.Sp
+On some machines, such as the Vax, this flag has no effect, because
+the standard calling sequence automatically handles the frame pointer
+and nothing is saved by pretending it doesn't exist. The
+machine-description macro \c
+.B FRAME_POINTER_REQUIRED\c
+\& controls
+whether a target machine supports this flag.
+.TP
+.B \-finline\-functions
+Integrate all simple functions into their callers. The compiler
+heuristically decides which functions are simple enough to be worth
+integrating in this way.
+.Sp
+If all calls to a given function are integrated, and the function is
+declared \c
+.B static\c
+\&, then GCC normally does not output the function as
+assembler code in its own right.
+.TP
+.B \-fcaller\-saves
+Enable values to be allocated in registers that will be clobbered by
+function calls, by emitting extra instructions to save and restore the
+registers around such calls. Such allocation is done only when it
+seems to result in better code than would otherwise be produced.
+.Sp
+This option is enabled by default on certain machines, usually those
+which have no call-preserved registers to use instead.
+.TP
+.B \-fkeep\-inline\-functions
+Even if all calls to a given function are integrated, and the function
+is declared \c
+.B static\c
+\&, nevertheless output a separate run-time
+callable version of the function.
+.TP
+.B \-fno\-function\-cse
+Do not put function addresses in registers; make each instruction that
+calls a constant function contain the function's address explicitly.
+.Sp
+This option results in less efficient code, but some strange hacks
+that alter the assembler output may be confused by the optimizations
+performed when this option is not used.
+.TP
+.B \-fno\-peephole
+Disable any machine-specific peephole optimizations.
+.TP
+.B \-ffast-math
+This option allows GCC to violate some ANSI or IEEE rules/specifications
+in the interest of optimizing code for speed. For example, it allows
+the compiler to assume arguments to the \c
+.B sqrt\c
+\& function are
+non-negative numbers.
+.Sp
+This option should never be turned on by any `\|\c
+.B \-O\c
+\&\|' option since
+it can result in incorrect output for programs which depend on
+an exact implementation of IEEE or ANSI rules/specifications for
+math functions.
+.PP
+The following options control specific optimizations. The `\|\c
+.B \-O2\c
+\&\|'
+option turns on all of these optimizations except `\|\c
+.B \-funroll\-loops\c
+\&\|'
+and `\|\c
+.B \-funroll\-all\-loops\c
+\&\|'.
+.PP
+The `\|\c
+.B \-O\c
+\&\|' option usually turns on
+the `\|\c
+.B \-fthread\-jumps\c
+\&\|' and `\|\c
+.B \-fdelayed\-branch\c
+\&\|' options, but
+specific machines may change the default optimizations.
+.PP
+You can use the following flags in the rare cases when \*(lqfine-tuning\*(rq
+of optimizations to be performed is desired.
+.TP
+.B \-fstrength\-reduce
+Perform the optimizations of loop strength reduction and
+elimination of iteration variables.
+.TP
+.B \-fthread\-jumps
+Perform optimizations where we check to see if a jump branches to a
+location where another comparison subsumed by the first is found. If
+so, the first branch is redirected to either the destination of the
+second branch or a point immediately following it, depending on whether
+the condition is known to be true or false.
+.TP
+.B \-funroll\-loops
+Perform the optimization of loop unrolling. This is only done for loops
+whose number of iterations can be determined at compile time or run time.
+.TP
+.B \-funroll\-all\-loops
+Perform the optimization of loop unrolling. This is done for all loops.
+This usually makes programs run more slowly.
+.TP
+.B \-fcse\-follow\-jumps
+In common subexpression elimination, scan through jump instructions
+when the target of the jump is not reached by any other path. For
+example, when CSE encounters an \c
+.B if\c
+\& statement with an
+.B else\c
+\& clause, CSE will follow the jump when the condition
+tested is false.
+.TP
+.B \-fcse\-skip\-blocks
+This is similar to `\|\c
+.B \-fcse\-follow\-jumps\c
+\&\|', but causes CSE to
+follow jumps which conditionally skip over blocks. When CSE
+encounters a simple \c
+.B if\c
+\& statement with no else clause,
+`\|\c
+.B \-fcse\-skip\-blocks\c
+\&\|' causes CSE to follow the jump around the
+body of the \c
+.B if\c
+\&.
+.TP
+.B \-frerun\-cse\-after\-loop
+Re-run common subexpression elimination after loop optimizations has been
+performed.
+.TP
+.B \-felide\-constructors
+Elide constructors when this seems plausible (C++ only). With this
+flag, GNU C++ initializes \c
+.B y\c
+\& directly from the call to \c
+.B foo
+without going through a temporary in the following code:
+.Sp
+A foo ();
+A y = foo ();
+.Sp
+Without this option, GNU C++ first initializes \c
+.B y\c
+\& by calling the
+appropriate constructor for type \c
+.B A\c
+\&; then assigns the result of
+.B foo\c
+\& to a temporary; and, finally, replaces the initial value of
+`\|\c
+.B y\c
+\&\|' with the temporary.
+.Sp
+The default behavior (`\|\c
+.B \-fno\-elide\-constructors\c
+\&\|') is specified by
+the draft ANSI C++ standard. If your program's constructors have side
+effects, using `\|\c
+.B \-felide-constructors\c
+\&\|' can make your program act
+differently, since some constructor calls may be omitted.
+.TP
+.B \-fexpensive\-optimizations
+Perform a number of minor optimizations that are relatively expensive.
+.TP
+.B \-fdelayed\-branch
+If supported for the target machine, attempt to reorder instructions
+to exploit instruction slots available after delayed branch
+instructions.
+.TP
+.B \-fschedule\-insns
+If supported for the target machine, attempt to reorder instructions to
+eliminate execution stalls due to required data being unavailable. This
+helps machines that have slow floating point or memory load instructions
+by allowing other instructions to be issued until the result of the load
+or floating point instruction is required.
+.TP
+.B \-fschedule\-insns2
+Similar to `\|\c
+.B \-fschedule\-insns\c
+\&\|', but requests an additional pass of
+instruction scheduling after register allocation has been done. This is
+especially useful on machines with a relatively small number of
+registers and where memory load instructions take more than one cycle.
+.SH TARGET OPTIONS
+By default, GNU CC compiles code for the same type of machine that you
+are using. However, it can also be installed as a cross-compiler, to
+compile for some other type of machine. In fact, several different
+configurations of GNU CC, for different target machines, can be
+installed side by side. Then you specify which one to use with the
+`\|\c
+.B \-b\c
+\&\|' option.
+.PP
+In addition, older and newer versions of GNU CC can be installed side
+by side. One of them (probably the newest) will be the default, but
+you may sometimes wish to use another.
+.TP
+.BI "\-b " "machine"
+The argument \c
+.I machine\c
+\& specifies the target machine for compilation.
+This is useful when you have installed GNU CC as a cross-compiler.
+.Sp
+The value to use for \c
+.I machine\c
+\& is the same as was specified as the
+machine type when configuring GNU CC as a cross-compiler. For
+example, if a cross-compiler was configured with `\|\c
+.B configure
+i386v\c
+\&\|', meaning to compile for an 80386 running System V, then you
+would specify `\|\c
+.B \-b i386v\c
+\&\|' to run that cross compiler.
+.Sp
+When you do not specify `\|\c
+.B \-b\c
+\&\|', it normally means to compile for
+the same type of machine that you are using.
+.TP
+.BI "\-V " "version"
+The argument \c
+.I version\c
+\& specifies which version of GNU CC to run.
+This is useful when multiple versions are installed. For example,
+.I version\c
+\& might be `\|\c
+.B 2.0\c
+\&\|', meaning to run GNU CC version 2.0.
+.Sp
+The default version, when you do not specify `\|\c
+.B \-V\c
+\&\|', is controlled
+by the way GNU CC is installed. Normally, it will be a version that
+is recommended for general use.
+.SH MACHINE DEPENDENT OPTIONS
+Each of the target machine types can have its own special options,
+starting with `\|\c
+.B \-m\c
+\&\|', to choose among various hardware models or
+configurations\(em\&for example, 68010 vs 68020, floating coprocessor or
+none. A single installed version of the compiler can compile for any
+model or configuration, according to the options specified.
+.PP
+Some configurations of the compiler also support additional special
+options, usually for command-line compatibility with other compilers on
+the same platform.
+.PP

+.TP
+.B \-m68020
+.TP
+.B \-mc68020
+Generate output for a 68020 (rather than a 68000). This is the
+default when the compiler is configured for 68020-based systems.
+.TP
+.B \-m68881
+Generate output containing 68881 instructions for floating point.
+This is the default for most 68020-based systems unless

+was specified when the compiler was configured.
+.TP

+Generate output for a 68030. This is the default when the compiler is

+Generate output for a 68040. This is the default when the compiler is
+configured for 68040-based systems.
+.TP
+.B \-m68020\-40
+Generate output for a 68040, without using any of the new instructions.

+Generate output containing Sun FPA instructions for floating point.
+.TP

+sources.
+.TP
+.B \-mrtd
+Use a different function-calling convention, in which functions
+that take a fixed number of arguments return with the \c

+instruction, which pops their arguments while returning. This
+saves one instruction in the caller since there is no need to pop

+efficient code for explicit calls when the
+.I bal
+instruction can be
+substituted by the assembler or linker, but less efficient code in other
+cases, such as calls via function pointers, or using a linker that doesn't
+support this optimization.
+.TP
+.B \-mtail\-call
+.TP
+.B \-mno\-tail\-call
+Do (or do not) make additional attempts (beyond those of the
+machine-independent portions of the compiler) to optimize tail-recursive
+calls into branches. You may not want to do this because the detection of
+cases where this is not valid is not totally complete. The default is
+.BR \-mno\-tail\-call .
+.TP
+.B \-mcomplex\-addr
+.TP
+.B \-mno\-complex\-addr
+Assume (or do not assume) that the use of a complex addressing mode is a
+win on this implementation of the i960. Complex addressing modes may not
+be worthwhile on the K-series, but they definitely are on the C-series.
+The default is currently
+.B \-mcomplex\-addr
+for all processors except
+the CB and CC.
+.TP
+.B \-mcode\-align
+.TP
+.B \-mno\-code\-align
+Align code to 8-byte boundaries for faster fetching (or don't bother).
+Currently turned on by default for C-series implementations only.
+.TP
+.B \-mic\-compat
+.TP
+.B \-mic2.0\-compat
+.TP
+.B \-mic3.0\-compat
+Enable compatibility with iC960 v2.0 or v3.0.
+.TP
+.B \-masm\-compat
+.TP
+.B \-mintel\-asm
+Enable compatibility with the iC960 assembler.
+.TP
+.B \-mstrict\-align
+.TP
+.B \-mno\-strict\-align
+Do not permit (do permit) unaligned accesses.
+.TP
+.B \-mold\-align
+Enable structure-alignment compatibility with Intel's gcc release version
+1.3 (based on gcc 1.37). Currently this is buggy in that
+.B #pragma align 1
+is always assumed as well, and cannot be turned off.
+.PP
+These `\|\c
+.B \-m\c
+\&\|' options are defined for the DEC Alpha implementations:
+.TP
+.B \-mno-soft-float
+.TP
+.B \-msoft-float
+Use (do not use) the hardware floating-point instructions for
+floating-point operations. When \c
+.B \-msoft-float\c
+\& is specified,
+functions in `\|\c
+.B libgcc1.c\c
+\&\|' will be used to perform floating-point
+operations. Unless they are replaced by routines that emulate the
+floating-point operations, or compiled in such a way as to call such
+emulations routines, these routines will issue floating-point
+operations. If you are compiling for an Alpha without floating-point
+operations, you must ensure that the library is built so as not to call
+them.
+.Sp
+Note that Alpha implementations without floating-point operations are
+required to have floating-point registers.
+.TP
+.B \-mfp-reg
+.TP
+.B \-mno-fp-regs
+Generate code that uses (does not use) the floating-point register set.
+.B \-mno-fp-regs\c
+\& implies \c
+.B \-msoft-float\c
+\&. If the floating-point
+register set is not used, floating point operands are passed in integer
+registers as if they were integers and floating-point results are passed
+in $0 instead of $f0. This is a non-standard calling sequence, so any
+function with a floating-point argument or return value called by code
+compiled with \c
+.B \-mno-fp-regs\c
+\& must also be compiled with that
+option.
+.Sp
+A typical use of this option is building a kernel that does not use,
+and hence need not save and restore, any floating-point registers.
+.PP
+These additional options are available on System V Release 4 for
+compatibility with other compilers on those systems:
+.TP
+.B \-G
+On SVr4 systems, \c
+.B gcc\c
+\& accepts the option `\|\c
+.B \-G\c
+\&\|' (and passes
+it to the system linker), for compatibility with other compilers.
+However, we suggest you use `\|\c
+.B \-symbolic\c
+\&\|' or `\|\c
+.B \-shared\c
+\&\|' as
+appropriate, instead of supplying linker options on the \c
+.B gcc
+command line.
+.TP
+.B \-Qy
+Identify the versions of each tool used by the compiler, in a
+.B .ident\c
+\& assembler directive in the output.
+.TP
+.B \-Qn
+Refrain from adding \c
+.B .ident\c
+\& directives to the output file (this is
+the default).
+.TP
+.BI "\-YP," "dirs"
+Search the directories \c
+.I dirs\c
+\&, and no others, for libraries
+specified with `\|\c
+.B \-l\c
+\&\|'. You can separate directory entries in
+.I dirs\c
+\& from one another with colons.
+.TP
+.BI "\-Ym," "dir"
+Look in the directory \c
+.I dir\c
+\& to find the M4 preprocessor.
+The assembler uses this option.
+.SH CODE GENERATION OPTIONS
+These machine-independent options control the interface conventions
+used in code generation.
+.PP
+Most of them begin with `\|\c
+\-f\c
+\&\|'. These options have both positive and negative forms; the negative form
+of `\|\c
+.B \-ffoo\c
+\&\|' would be `\|\c
+.B \-fno\-foo\c
+\&\|'. In the table below, only
+one of the forms is listed\(em\&the one which is not the default. You
+can figure out the other form by either removing `\|\c
+.B no\-\c
+\&\|' or adding
+it.
+.TP
+.B \-fnonnull\-objects
+Assume that objects reached through references are not null
+(C++ only).
+.Sp
+Normally, GNU C++ makes conservative assumptions about objects reached
+through references. For example, the compiler must check that \c
+.B a
+is not null in code like the following:
+.Sp
+obj &a = g ();
+a.f (2);
+.Sp
+Checking that references of this sort have non-null values requires
+extra code, however, and it is unnecessary for many programs. You can
+use `\|\c
+.B \-fnonnull-objects\c
+\&\|' to omit the checks for null, if your
+program doesn't require checking.
+.TP
+.B \-fpcc\-struct\-return
+Use the same convention for returning \c
+.B struct\c
+\& and \c
+.B union
+values that is used by the usual C compiler on your system. This
+convention is less efficient for small structures, and on many
+machines it fails to be reentrant; but it has the advantage of
+allowing intercallability between GCC-compiled code and PCC-compiled
+code.
+.TP
+.B \-freg\-struct\-return
+Use the convention that
+.B struct
+and
+.B union
+values are returned in registers when possible. This is more
+efficient for small structures than
+.BR \-fpcc\-struct\-return .
+.Sp
+If you specify neither
+.B \-fpcc\-struct\-return
+nor
+.BR \-freg\-struct\-return ,
+GNU CC defaults to whichever convention is standard for the target.
+If there is no standard convention, GNU CC defaults to
+.BR \-fpcc\-struct\-return .
+.TP
+.B \-fshort\-enums
+Allocate to an \c
+.B enum\c
+\& type only as many bytes as it needs for the
+declared range of possible values. Specifically, the \c
+.B enum\c
+\& type
+will be equivalent to the smallest integer type which has enough room.
+.TP
+.B \-fshort\-double
+Use the same size for
+.B double
+as for
+.B float
+\&.
+.TP
+.B \-fshared\-data
+Requests that the data and non-\c
+.B const\c
+\& variables of this
+compilation be shared data rather than private data. The distinction
+makes sense only on certain operating systems, where shared data is
+shared between processes running the same program, while private data
+exists in one copy per process.
+.TP
+.B \-fno\-common
+Allocate even uninitialized global variables in the bss section of the
+object file, rather than generating them as common blocks. This has the
+effect that if the same variable is declared (without \c
+.B extern\c
+\&) in
+two different compilations, you will get an error when you link them.
+The only reason this might be useful is if you wish to verify that the
+program will work on other systems which always work this way.
+.TP
+.B \-fno\-ident
+Ignore the `\|\c
+.B #ident\c
+\&\|' directive.
+.TP
+.B \-fno\-gnu\-linker
+Do not output global initializations (such as C++ constructors and
+destructors) in the form used by the GNU linker (on systems where the GNU
+linker is the standard method of handling them). Use this option when
+you want to use a non-GNU linker, which also requires using the
+.B collect2\c
+\& program to make sure the system linker includes
+constructors and destructors. (\c
+.B collect2\c
+\& is included in the GNU CC
+distribution.) For systems which \c
+.I must\c
+\& use \c
+.B collect2\c
+\&, the
+compiler driver \c
+.B gcc\c
+\& is configured to do this automatically.
+.TP
+.B \-finhibit-size-directive
+Don't output a \c
+.B .size\c
+\& assembler directive, or anything else that
+would cause trouble if the function is split in the middle, and the
+two halves are placed at locations far apart in memory. This option is
+used when compiling `\|\c
+.B crtstuff.c\c
+\&\|'; you should not need to use it
+for anything else.
+.TP
+.B \-fverbose-asm
+Put extra commentary information in the generated assembly code to
+make it more readable. This option is generally only of use to those
+who actually need to read the generated assembly code (perhaps while
+debugging the compiler itself).
+.TP
+.B \-fvolatile
+Consider all memory references through pointers to be volatile.
+.TP
+.B \-fvolatile\-global
+Consider all memory references to extern and global data items to
+be volatile.
+.TP
+.B \-fpic
+If supported for the target machines, generate position-independent code,
+suitable for use in a shared library.
+.TP
+.B \-fPIC
+If supported for the target machine, emit position-independent code,
+suitable for dynamic linking, even if branches need large displacements.
+.TP
+.BI "\-ffixed\-" "reg"
+Treat the register named \c
+.I reg\c
+\& as a fixed register; generated code
+should never refer to it (except perhaps as a stack pointer, frame
+pointer or in some other fixed role).
+.Sp
+.I reg\c
+\& must be the name of a register. The register names accepted
+are machine-specific and are defined in the \c
+.B REGISTER_NAMES
+macro in the machine description macro file.
+.Sp
+This flag does not have a negative form, because it specifies a
+three-way choice.
+.TP
+.BI "\-fcall\-used\-" "reg"
+Treat the register named \c
+.I reg\c
+\& as an allocatable register that is
+clobbered by function calls. It may be allocated for temporaries or
+variables that do not live across a call. Functions compiled this way
+will not save and restore the register \c
+.I reg\c
+\&.
+.Sp
+Use of this flag for a register that has a fixed pervasive role in the
+machine's execution model, such as the stack pointer or frame pointer,
+will produce disastrous results.
+.Sp
+This flag does not have a negative form, because it specifies a
+three-way choice.
+.TP
+.BI "\-fcall\-saved\-" "reg"
+Treat the register named \c
+.I reg\c
+\& as an allocatable register saved by
+functions. It may be allocated even for temporaries or variables that
+live across a call. Functions compiled this way will save and restore
+the register \c
+.I reg\c
+\& if they use it.
+.Sp
+Use of this flag for a register that has a fixed pervasive role in the
+machine's execution model, such as the stack pointer or frame pointer,
+will produce disastrous results.
+.Sp
+A different sort of disaster will result from the use of this flag for
+a register in which function values may be returned.
+.Sp
+This flag does not have a negative form, because it specifies a
+three-way choice.
+.SH PRAGMAS
+Two `\|\c
+.B #pragma\c
+\&\|' directives are supported for GNU C++, to permit using the same
+header file for two purposes: as a definition of interfaces to a given
+object class, and as the full definition of the contents of that object class.
+.TP
+.B #pragma interface
+(C++ only.)
+Use this directive in header files that define object classes, to save
+space in most of the object files that use those classes. Normally,
+local copies of certain information (backup copies of inline member
+functions, debugging information, and the internal tables that
+implement virtual functions) must be kept in each object file that
+includes class definitions. You can use this pragma to avoid such
+duplication. When a header file containing `\|\c
+.B #pragma interface\c
+\&\|' is included in a compilation, this auxiliary information
+will not be generated (unless the main input source file itself uses
+`\|\c
+.B #pragma implementation\c
+\&\|'). Instead, the object files will contain references to be
+resolved at link time.
+.TP
+.B #pragma implementation
+.TP
+\fB#pragma implementation "\fP\fIobjects\fP\fB.h"\fP
+(C++ only.)
+Use this pragma in a main input file, when you want full output from
+included header files to be generated (and made globally visible).
+The included header file, in turn, should use `\|\c
+.B #pragma interface\c
+\&\|'.
+Backup copies of inline member functions, debugging information, and
+the internal tables used to implement virtual functions are all
+generated in implementation files.
+.Sp
+If you use `\|\c
+.B #pragma implementation\c
+\&\|' with no argument, it applies to an include file with the same
+basename as your source file; for example, in `\|\c
+.B allclass.cc\c
+\&\|', `\|\c
+.B #pragma implementation\c
+\&\|' by itself is equivalent to `\|\c
+.B
+#pragma implementation "allclass.h"\c
+\&\|'. Use the string argument if you want a single implementation
+file to include code from multiple header files.
+.Sp
+There is no way to split up the contents of a single header file into
+multiple implementation files.

+1 GCC
+
+ The GCC command invokes the GNU C compiler.
+
+ GCC file-spec
+
+2 Parameters
+
+ file-spec
+
+ A C source file. If no input file extension is specified, GNU C
+ assumes .C as the default extension unless the /PLUS qualifier is
+ given, in which case .CC is assumed as the default extension.
+
+ If an extension of .CPP is given, then the source file is assumed to
+ be the output of the preprocessor, and thus the preprocessor is not
+ executed.
+
+ If an extension of .S is given, then the source file is assumed to be
+ the assembly code output of the compiler, and only the assembler is
+ called to generate an object file.
+
+2 Qualifiers
+
+ GNU C command qualifiers modify the way the compiler handles the
+ compilation.
+
+ The following is the list of available qualifiers for GNU C:
+
+ /CASE_HACK
+ /CC1_OPTIONS=(option [,option...]])
+ /DEBUG
+ /DEFINE=(identifier[=definition][,...])
+ /G_FLOAT
+ /INCLUDE_DIRECTORY=(path [,path...]])
+ /LIST[=filename]
+ /MACHINE_CODE
+ /OBJECT[=filename]
+ /OPTIMIZE
+ /PLUS
+ /PROFILE[=identifier]
+ /SCAN=(file[,file...])
+ /SHOW[=option]
+ /UNDEFINE=(identifier[,identifier,...])
+ /VERBOSE
+ /VERSION
+ /WARNING
+
+2 Linking
+
+ When linking programs compiled with GNU C, you should include the GNU
+ C library before the VAX C library. For example,
+
+ LINK object-file,GNU_CC:[000000]GCCLIB/LIB,SYS$LIBRARY:VAXCRTL/LIB
+
+ You can also link your program with the shared VAX C library. This
+ can reduce the size of the .EXE file, as well as make it smaller when
+ it's running. For example,
+
+ $ LINK object-file, GNU_CC:[000000]GCCLIB/LIB,SYS$INPUT/OPT
+ SYS$SHARE:VAXCRTL/SHARE
+
+ (If you use the second example and type it in by hand, be sure to
+ type ^Z after the last carriage return). A simpler alternative would
+ be to place the single line:
+
+ SYS$SHARE:VAXCRTL/SHARE
+
+ into a file called VAXCRTL.OPT, and then use the link command:
+
+ $ LINK object-file, GNU_CC:[000000]GCCLIB/LIB,VAXCRTL.OPT/OPT
+
+ If a program has been compiled with /G_FLOAT, then the linking
+ instructions are slightly different. If you are linking with the
+ non-shared library, then the command that you should use would be:
+
+ LINK object-file,GNU_CC:[000000]GCCLIB/LIB,SYS$LIBRARY:VAXCRTLG/LIB -
+ ,SYS$LIBRARY:VAXCRTL/LIB
+
+ Note that both VAXCRTL and VAXCRTLG must be linked to. If you are
+ using the shared VAX C library, then you should use a command like:
+
+ $ LINK object-file, GNU_CC:[000000]GCCLIB/LIB,SYS$INPUT:/OPTIONS
+ SYS$SHARE:VAXCRTLG/SHARE
+
+ In the case of the sharable library, only one library needs to be
+ linked to.
+
+ If you need to link to libg++, it is easiest to use the command
+ procedure supplied with libg++ to link your program.
+
+2 /CASE_HACK
+
+ /[NO]CASE_HACK D=/CASE_HACK
+
+ Since the VMS Linker and Librarian are not case sensitive with
+ respect to symbol names, a "case-hack" is appended to a symbol name
+ when the symbol contains upper case characters.
+
+ There are cases where this is undesirable, (mainly when using certain
+ applications where modules have been precompiled, perhaps in another
+ language) and we want to compile without case hacking. In these
+ cases the /NOCASE_HACK switch disables case hacking.
+
+2 /CC1_OPTIONS
+
+ This specifies additional switches to the compiler itself which
+ cannot be set by means of the compiler driver.
+
+2 /DEBUG
+
+ /DEBUG includes additional information in the object file output so
+ that the program can be debugged with the VAX Symbolic Debugger.
+
+ To use the debugger it is also necessary to link the debugger to your
+ program, which is done by specifying the /DEBUG qualifier to the link
+ command. With the debugger it is possible to set breakpoints,
+ examine variables, and set variables to new values. See the VAX
+ Symbolic Debugger manual for more information, or type "HELP" from
+ the debugger prompt.
+
+2 /DEFINE
+
+ /DEFINE=(identifier[=definition][,...])
+
+ /DEFINE defines a string or macro ('definition') to be substituted
+ for every occurrence of a given string ('identifier') in a program.
+ It is equivalent to the #define preprocessor directive.
+
+ All definitions and identifiers are converted to uppercase unless
+ they are in quotation marks.
+
+ The simple form of the /DEFINE qualifier:
+
+ /DEFINE=vms
+
+ results in a definition equivalent to the preprocessor directive:
+
+ #define VMS 1
+
+ You must enclose macro definitions in quotation marks, as in this
+ example:
+
+ /DEFINE="C(x)=((x) & 0xff)"
+
+ This definition is the same as the preprocessor definition:
+
+ #define C(x) ((x) & 0xff)
+
+ If more than one /DEFINE is present on the GCC command line, only the
+ last /DEFINE is used.
+
+ If both /DEFINE and /UNDEFINE are present on a command line, /DEFINE
+ is evaluated before /UNDEFINE.
+
+2 /G_FLOAT
+
+ Instructs the compiler to use "G" floating point arithmetic instead
+ of "D". The difference is that double precision has a range of
+ approximately +/-0.56e-308 to +/-0.9 e+308, with approximately 15
+ decimal digits precision.
+
+ "D" floating point has the same range as single precision floating
+ point, with approximately 17 decimal digits precision.
+
+ If you use the /G_FLOAT qualifier, the linking instructions are
+ different. See "Linking" for further details.
+
+2 /LIST
+
+ /LIST[=list_file_name]
+
+ This does not generate a listing file in the usual sense, however it
+ does direct the compiler to save the preprocessor output. If a file
+ is not specified, then this output is written into a file with the
+ same name as the source file and an extension of .CPP.
+
+2 /INCLUDE_DIRECTORY
+
+ /INCLUDE_DIRECTORY=(path [,path...])
+
+ The /INCLUDE_DIRECTORY qualifier provides additional directories to
+ search for user-defined include files. 'path' can be either a
+ logical name or a directory specification.
+
+ There are two forms for specifying include files - #include
+ "file-spec" and #include <file-spec>. For the #include "file-spec"
+ form, the search order is:
+
+ 1. The directory containing the source file.
+
+ 2. The directories in the /INCLUDE qualifier (if any).
+
+ 3. The directory (or directories) specified in the logical name
+ GNU_CC_INCLUDE.
+
+ 4. The directory (or directories) specified in the logical name
+ SYS$LIBRARY.
+
+ For the #include <file-spec> form, the search order is:
+
+ 1. The directories specified in the /INCLUDE qualifier (if any).
+
+ 2. The directory (or directories) specified in the logical name
+ GNU_CC_INCLUDE.
+
+ 3. The directory (or directories) specified in the logical name
+ SYS$LIBRARY.
+
+2 /MACHINE_CODE
+
+ Tells GNU C to output the machine code generated by the compiler.
+ The machine code is output to a file with the same name as the input
+ file, with the extension .S. An object file is still generated,
+ unless /NOOBJ is also specified.
+
+2 /OBJECT
+
+ /OBJECT[=filename]
+ /NOOBJECT
+
+ Controls whether or not an object file is generated by the
+ compiler.
+
+2 /OPTIMIZE
+
+ /[NO]OPTIMIZE
+
+ Controls whether optimization is performed by the compiler. By
+ default, optimization is on. /NOOPTIMIZE turns optimization off.
+
+2 /PLUS
+
+ Instructs the compiler driver to use the GNU-C++ compiler instead of
+ the GNU-C compiler. Note that the default extension of source files
+ is .CC when this qualifier is in effect.
+
+2 /PROFILE
+
+ /PROFILE[=identifier]
+
+ Instructs the compiler to generate function profiling code. You must
+ link your program to the profiler when you use this options. The
+ profile statistics are automatically printed out on the terminal
+ during image exit. (i.e. no modifications to your source file are
+ required in order to use the profiler).
+
+ There are three identifiers that can be used with the /PROFILE
+ switch. These are ALL, FUNCTION, and BLOCK. If /PROFILE is given
+ without an identifier, then FUNCTION is assumed.
+
+3 Block_Profiler
+
+ The block profiler counts how many times control of the program
+ passes certain points in your program. This is useful in determining
+ which portions of a program would benefit from recoding for
+ optimization.
+
+ The report for the block profiler contains the function name, file
+ name, PC, and the source file line number as well as the count of how
+ many times control has passed through the specified source line.
+
+3 Function_Profiler
+
+ The function profiler counts how many times each function is entered,
+ and keeps track of how much CPU time is used within each function.
+
+ You should be careful about interpreting the results of profiles
+ where there are inline functions. When a function is included as
+ inline, then there is no call to the internal data collection routine
+ used by the profiler, and thus there will be no record of this
+ function being called. The compiler does generate a callable version
+ of each inline function, and if this called version is used, then the
+ profiler's data collection routine will be called.
+
+2 /SCAN
+
+ /SCAN=(file[,file...])
+
+ This qualifier supplies a list of files that will be read as input,
+ and the output will be discarded before processing the regular input
+ file. Because the output generated from the files is discarded, the
+ only effect of this qualifier is to make the macros defined in the
+ files available for use in the main input.
+
+2 /SHOW
+
+ /SHOW[=option]
+
+ This causes the preprocessor to generate information other than the
+ preprocessed input file. When this qualifier is used, no assembly
+ code and no object file is generated.
+
+ The output of the preprocessor is placed in the file specified by the
+ /LIST qualifier, if present. If the /LIST qualifier is not present,
+ then the output is placed in a file with the same name as the input
+ file with an extension that depends upon which option that is
+ selected.
+
+3 DEFINITIONS
+
+ This option causes the preprocessor to dump a list of all of the
+ definitions to the output file. This is useful for debugging
+ purposes, since it lets you determine whether or not everything has
+ been defined properly.
+
+ If the default file name is used for the output, the extension will
+ be .DEF.
+
+3 RULES
+
+ This option causes the preprocessor to output a rule suitable for
+ MAKE, describing the dependencies of the main source file. The
+ preprocessor outputs one MAKE rule containing the object file name
+ for that source file, a colon, and the names of all the concluded
+ files. If there are many included files then the rule is split into
+ several lines using the '\'-newline.
+
+ When using this option, only files included with the "#include "file"
+ directive are mentioned.
+
+ If the default file name is used for the output, a null extension
+ will be used.
+
+3 ALL
+
+ This option is similar to RULES, except that it also mentions files
+ included with the "#include <file.h>" directive.
+
+ If the default file name is used for the output, a null extension
+ will be used.
+
+2 /UNDEFINE
+
+ /UNDEFINE cancels a macro definition. Thus, it is the same as the
+ #undef preprocessor directive.
+
+ If more than one /UNDEFINE is present on the GCC command line, only
+ the last /UNDEFINE is used.
+
+ If both /DEFINE and /UNDEFINE are present on a command line, /DEFINE
+ is evaluated before /UNDEFINE.
+
+2 /VERBOSE
+
+ Controls whether the user sees the invocation command strings for the
+ preprocessor, compiler, and assembler. The compiler also outputs
+ some statistics on time spent in its various phases.
+
+2 /VERSION
+
+ Causes the preprocessor and the compiler to identify themselves by
+ their version numbers, and in the case of the compiler, the version
+ number of the compiler that built it.
+
+2 /WARNING
+
+ When this qualifier is present, warnings about usage that should be
+ avoided are given by the compiler. For more information, see "Using
+ and Porting GNU CC", in the section on command line options, under
+ "-Wall".
+
+ Warnings are also generated by the preprocessor when this qualifier
+ is given.
+
+2 Known_Incompatibilities_with_VAX-C
+
+ There are several known incompatibilities between GNU-C and VAX-C.
+ Some common ones will be briefly described here. A complete
+ description can be found in "Using and Porting GNU CC" in the chapter
+ entitled "Using GNU CC on VMS".
+
+ GNU-C provides case hacking as a means of giving case sensitivity
+ to symbol names. The case hack is a hexadecimal number appended to
+ the symbol name, with a bit being set for each upper case letter.
+ Symbols with all lower case, or symbols that have a dollar sign ("$")
+ are not case hacked. There are times that this is undesirable,
+ namely when you wish to link your program against a precompiled
+ library which was compiled with a non-GNU-C compiler. X-windows (or
+ DECWindows) is an example of this. In these instances, the
+ /NOCASE_HACK switch should be used.
+
+ If you require case hacking in some cases, but not in others (i.e.
+ Libg++ with DECWindows), then it is recommended that you develop a
+ header file which will define all mixed case functions that should
+ not have a case hack as the lower case equivalents.
+
+ GNU-C does not provide the globaldef and globalref mechanism
+ which is used by VAX-C to coerce the VMS linker to include certain
+ object modules from a library. There are assembler hacks, which are
+ available to the user through the macros defined in gnu_hacks.h,
+ which effectively give you the ability to perform these functions.
+ While not syntactically identical, they do provide most of the
+ functionality.
+
+ Note that globaldefs of enums is not supported in the way that it is
+ under VAX-C. This can be easily simulated, however, by globaldefing
+ an integer variable, and then globalvaluing all of the enumerated
+ states.
+
+ Furthermore, the way that globalvalue is currently implemented, the
+ data type of the globalvalue variable is seen to the compiler to be a
+ pointer to the data type that you specify. This is necessary in
+ order to make the compiler correctly address the globalvalue
+ variables.

+@chapter Compile C, C++, or Objective C
+
+@cindex Objective C
+The C, C++, and Objective C versions of the compiler are integrated; the
+GNU C compiler can compile programs written in C, C++, or Objective C.
+
+@cindex GCC
+``GCC'' is a common shorthand term for the GNU C compiler. This is both
+the most general name for the compiler, and the name used when the
+emphasis is on compiling C programs.
+
+@cindex C++
+@cindex G++
+When referring to C++ compilation, it is usual to call the compiler
+``G++''. Since there is only one compiler, it is also accurate to call
+it ``GCC'' no matter what the language context; however, the term
+``G++'' is more useful when the emphasis is on compiling C++ programs.
+
+We use the name ``GNU CC'' to refer to the compilation system as a
+whole, and more specifically to the language-independent part of the
+compiler. For example, we refer to the optimization options as
+affecting the behavior of ``GNU CC'' or sometimes just ``the compiler''.
+
+Front ends for other languages, such as Ada 9X, Fortran, Modula-3, and
+Pascal, are under development. These front-ends, like that for C++, are
+built in subdirectories of GNU CC and link to it. The result is an
+integrated compiler that can compile programs written in C, C++,
+Objective C, or any of the languages for which you have installed front
+ends.
+
+In this manual, we only discuss the options for the C, Objective-C, and
+C++ compilers and those of the GNU CC core. Consult the documentation
+of the other front ends for the options to use when compiling programs
+written in other languages.
+
+@cindex compiler compared to C++ preprocessor
+@cindex intermediate C version, nonexistent
+@cindex C intermediate output, nonexistent
+G++ is a @emph{compiler}, not merely a preprocessor. G++ builds object
+code directly from your C++ program source. There is no intermediate C
+version of the program. (By contrast, for example, some other
+implementations use a program that generates a C program from your C++
+source.) Avoiding an intermediate C representation of the program means
+that you get better object code, and better debugging information. The
+GNU debugger, GDB, works with this information in the object code to
+give you comprehensive C++ source-level editing capabilities
+(@pxref{C,,C and C++,gdb.info, Debugging with GDB}).
+
+@c FIXME! Someone who knows something about Objective C ought to put in
+@c a paragraph or two about it here, and move the index entry down when
+@c there is more to point to than the general mention in the 1st par.

+@node Actual Bugs
+@section Actual Bugs We Haven't Fixed Yet
+
+@itemize @bullet
+@item
+The @code{fixincludes} script interacts badly with automounters; if the
+directory of system header files is automounted, it tends to be
+unmounted while @code{fixincludes} is running. This would seem to be a
+bug in the automounter. We don't know any good way to work around it.
+
+@item
+The @code{fixproto} script will sometimes add prototypes for the
+@code{sigsetjmp} and @code{siglongjmp} functions that reference the
+@code{jmp_buf} type before that type is defined. To work around this,
+edit the offending file and place the typedef in front of the
+prototypes.
+
+@item
+There are several obscure case of mis-using struct, union, and
+enum tags that are not detected as errors by the compiler.
+
+@item
+When @samp{-pedantic-errors} is specified, GNU C will incorrectly give
+an error message when a function name is specified in an expression
+involving the comma operator.
+
+@item
+Loop unrolling doesn't work properly for certain C++ programs. This is
+a bug in the C++ front end. It sometimes emits incorrect debug info, and
+the loop unrolling code is unable to recover from this error.
+@end itemize
+
+@node Installation Problems
+@section Installation Problems
+
+This is a list of problems (and some apparent problems which don't
+really mean anything is wrong) that show up during installation of GNU
+CC.
+
+@itemize @bullet
+@item
+On certain systems, defining certain environment variables such as
+@code{CC} can interfere with the functioning of @code{make}.
+
+@item
+If you encounter seemingly strange errors when trying to build the
+compiler in a directory other than the source directory, it could be
+because you have previously configured the compiler in the source
+directory. Make sure you have done all the necessary preparations.
+@xref{Other Dir}.
+
+@item
+If you build GNU CC on a BSD system using a directory stored in a System
+V file system, problems may occur in running @code{fixincludes} if the
+System V file system doesn't support symbolic links. These problems
+result in a failure to fix the declaration of @code{size_t} in
+@file{sys/types.h}. If you find that @code{size_t} is a signed type and
+that type mismatches occur, this could be the cause.
+
+The solution is not to use such a directory for building GNU CC.
+
+@item
+In previous versions of GNU CC, the @code{gcc} driver program looked for
+@code{as} and @code{ld} in various places; for example, in files
+beginning with @file{/usr/local/lib/gcc-}. GNU CC version 2 looks for
+them in the directory
+@file{/usr/local/lib/gcc-lib/@var{target}/@var{version}}.
+
+Thus, to use a version of @code{as} or @code{ld} that is not the system
+default, for example @code{gas} or GNU @code{ld}, you must put them in
+that directory (or make links to them from that directory).
+
+@item
+Some commands executed when making the compiler may fail (return a
+non-zero status) and be ignored by @code{make}. These failures, which
+are often due to files that were not found, are expected, and can safely
+be ignored.
+
+@item
+It is normal to have warnings in compiling certain files about
+unreachable code and about enumeration type clashes. These files' names
+begin with @samp{insn-}. Also, @file{real.c} may get some warnings that
+you can ignore.
+
+@item
+Sometimes @code{make} recompiles parts of the compiler when installing
+the compiler. In one case, this was traced down to a bug in
+@code{make}. Either ignore the problem or switch to GNU Make.
+
+@item
+If you have installed a program known as purify, you may find that it
+causes errors while linking @code{enquire}, which is part of building
+GNU CC. The fix is to get rid of the file @code{real-ld} which purify
+installs---so that GNU CC won't try to use it.
+
+@item
+On Linux SLS 1.01, there is a problem with @file{libc.a}: it does not
+contain the obstack functions. However, GNU CC assumes that the obstack
+functions are in @file{libc.a} when it is the GNU C library. To work
+around this problem, change the @code{__GNU_LIBRARY__} conditional
+around line 31 to @samp{#if 1}.
+
+@item
+On some 386 systems, building the compiler never finishes because
+@code{enquire} hangs due to a hardware problem in the motherboard---it
+reports floating point exceptions to the kernel incorrectly. You can
+install GNU CC except for @file{float.h} by patching out the command to
+run @code{enquire}. You may also be able to fix the problem for real by
+getting a replacement motherboard. This problem was observed in
+Revision E of the Micronics motherboard, and is fixed in Revision F.
+It has also been observed in the MYLEX MXA-33 motherboard.
+
+If you encounter this problem, you may also want to consider removing
+the FPU from the socket during the compilation. Alternatively, if you
+are running SCO Unix, you can reboot and force the FPU to be ignored.
+To do this, type @samp{hd(40)unix auto ignorefpu}.
+
+@item
+On some 386 systems, GNU CC crashes trying to compile @file{enquire.c}.
+This happens on machines that don't have a 387 FPU chip. On 386
+machines, the system kernel is supposed to emulate the 387 when you
+don't have one. The crash is due to a bug in the emulator.
+
+One of these systems is the Unix from Interactive Systems: 386/ix.
+On this system, an alternate emulator is provided, and it does work.
+To use it, execute this command as super-user:
+
+@example
+ln /etc/emulator.rel1 /etc/emulator
+@end example
+
+@noindent
+and then reboot the system. (The default emulator file remains present
+under the name @file{emulator.dflt}.)
+
+Try using @file{/etc/emulator.att}, if you have such a problem on the
+SCO system.
+
+Another system which has this problem is Esix. We don't know whether it
+has an alternate emulator that works.
+
+On NetBSD 0.8, a similar problem manifests itself as these error messages:
+
+@example
+enquire.c: In function `fprop':
+enquire.c:2328: floating overflow
+@end example
+
+@item
+On SCO systems, when compiling GNU CC with the system's compiler,
+do not use @samp{-O}. Some versions of the system's compiler miscompile
+GNU CC with @samp{-O}.
+
+@cindex @code{genflags}, crash on Sun 4
+@item
+Sometimes on a Sun 4 you may observe a crash in the program
+@code{genflags} or @code{genoutput} while building GNU CC. This is said to

+On Solaris 2, executables of GNU CC version 2.0.2 are commonly
+available, but they have a bug that shows up when compiling current
+versions of GNU CC: undefined symbol errors occur during assembly if you
+use @samp{-g}.
+
+The solution is to compile the current version of GNU CC without
+@samp{-g}. That makes a working compiler which you can use to recompile
+with @samp{-g}.
+
+@item
+Solaris 2 comes with a number of optional OS packages. Some of these
+packages are needed to use GNU CC fully. If you did not install all
+optional packages when installing Solaris, you will need to verify that
+the packages that GNU CC needs are installed.
+
+To check whether an optional package is installed, use
+the @code{pkginfo} command. To add an optional package, use the
+@code{pkgadd} command. For further details, see the Solaris
+documentation.
+
+For Solaris 2.0 and 2.1, GNU CC needs six packages: @samp{SUNWarc},
+@samp{SUNWbtool}, @samp{SUNWesu}, @samp{SUNWhea}, @samp{SUNWlibm}, and
+@samp{SUNWtoo}.
+
+For Solaris 2.2, GNU CC needs an additional seventh package: @samp{SUNWsprot}.
+
+@item
+On Solaris 2, trying to use the linker and other tools in
+@file{/usr/ucb} to install GNU CC has been observed to cause trouble.
+For example, the linker may hang indefinitely. The fix is to remove
+@file{/usr/ucb} from your @code{PATH}.
+
+@item
+If you use the 1.31 version of the MIPS assembler (such as was shipped
+with Ultrix 3.1), you will need to use the -fno-delayed-branch switch
+when optimizing floating point code. Otherwise, the assembler will
+complain when the GCC compiler fills a branch delay slot with a
+floating point instruction, such as @code{add.d}.
+
+@item
+If on a MIPS system you get an error message saying ``does not have gp
+sections for all it's [sic] sectons [sic]'', don't worry about it. This
+happens whenever you use GAS with the MIPS linker, but there is not
+really anything wrong, and it is okay to use the output file. You can
+stop such warnings by installing the GNU linker.
+
+It would be nice to extend GAS to produce the gp tables, but they are
+optional, and there should not be a warning about their absence.
+
+@item
+In Ultrix 4.0 on the MIPS machine, @file{stdio.h} does not work with GNU

+away.
+
+To work around this problem, when making the stage 1 compiler, specify
+this option to Make:
+
+@example
+GCC_FOR_TARGET="./xgcc -B./ -I./include"

+Some versions of the MIPS linker will issue an assertion failure
+when linking code that uses @code{alloca} against shared
+libraries on RISC-OS 5.0, and DEC's OSF/1 systems. This is a bug
+in the linker, that is supposed to be fixed in future revisions.
+To protect against this, GNU CC passes @samp{-non_shared} to the
+linker unless you pass an explicit @samp{-shared} or
+@samp{-call_shared} switch.

+On System V release 3, you may get this error message
+while linking:
+
+@smallexample
+ld fatal: failed to write symbol name @var{something}

+@end smallexample
+
+This probably indicates that the disk is full or your ULIMIT won't allow
+the file to be as large as it needs to be.
+
+This problem can also result because the kernel parameter @code{MAXUMEM}
+is too small. If so, you must regenerate the kernel and make the value
+much larger. The default value is reported to be 1024; a value of 32768
+is said to work. Smaller values may also work.

+@example
+/usr/local/lib/bison.simple: In function `yyparse':

+On HP 9000 series 300 or 400 running HP-UX release 8.0, there is a bug

+The bug is not really in the assembler, but in the shared library
+version of the function ``cvtnum(3c)''. The bug on ``cvtnum(3c)'' is
+SR#4701-078451. Anyway, the attached assembler uses the archive

+On HP-UX version 8.05, but not on 8.07 or more recent versions,

+Some versions of the Pyramid C compiler are reported to be unable to
+compile GNU CC. You must use an older version of GNU CC for

+when GNU CC compiles the function @code{muldi3} in file @file{libgcc2.c}.
+
+You may be able to succeed by getting GNU CC version 1, installing it,
+and using it to compile GNU CC version 2. The bug in the Pyramid C

+@file{iclib.a}. You must also modify @file{stdio.h} as follows: before
+the lines
+
+@example
+#if defined(__i860__) && !defined(_VA_LIST)

+@node Cross-Compiler Problems
+@section Cross-Compiler Problems
+
+You may run into problems with cross compilation on certain machines,
+for several reasons.
+
+@itemize @bullet
+@item
+Cross compilation can run into trouble for certain machines because
+some target machines' assemblers require floating point numbers to be
+written as @emph{integer} constants in certain contexts.
+
+The compiler writes these integer constants by examining the floating
+point value as an integer and printing that integer, because this is
+simple to write and independent of the details of the floating point
+representation. But this does not work if the compiler is running on
+a different machine with an incompatible floating point format, or
+even a different byte-ordering.
+
+In addition, correct constant folding of floating point values
+requires representing them in the target machine's format.
+(The C standard does not quite require this, but in practice
+it is the only way to win.)
+
+It is now possible to overcome these problems by defining macros such
+as @code{REAL_VALUE_TYPE}. But doing so is a substantial amount of
+work for each target machine.

+
+This section lists various difficulties encountered in using GNU C or
+GNU C++ together with other compilers or with the assemblers, linkers,
+libraries and debuggers on certain systems.
+
+@itemize @bullet
+@item
+Objective C does not work on the RS/6000.
+
+@item
+GNU C++ does not do name mangling in the same way as other C++
+compilers. This means that object files compiled with one compiler
+cannot be used with another.
+
+This effect is intentional, to protect you from more subtle problems.
+Compilers differ as to many internal details of C++ implementation,
+including: how class instances are laid out, how multiple inheritance is
+implemented, and how virtual function calls are handled. If the name
+encoding were made the same, your programs would link against libraries
+provided from other compilers---but the programs would then crash when
+run. Incompatible libraries are then detected at link time, rather than
+at run time.
+
+@item
+Older GDB versions sometimes fail to read the output of GNU CC version
+2. If you have trouble, get GDB version 4.4 or later.
+
+@item
+@cindex DBX
+DBX rejects some files produced by GNU CC, though it accepts similar
+constructs in output from PCC. Until someone can supply a coherent
+description of what is valid DBX input and what is not, there is
+nothing I can do about these problems. You are on your own.
+
+@item
+The GNU assembler (GAS) does not support PIC. To generate PIC code, you
+must use some other assembler, such as @file{/bin/as}.
+
+@item
+On some BSD systems, including some versions of Ultrix, use of profiling
+causes static variable destructors (currently used only in C++) not to
+be run.
+
+@item
+Use of @samp{-I/usr/include} may cause trouble.
+
+Many systems come with header files that won't work with GNU CC unless
+corrected by @code{fixincludes}. The corrected header files go in a new
+directory; GNU CC searches this directory before @file{/usr/include}.
+If you use @samp{-I/usr/include}, this tells GNU CC to search
+@file{/usr/include} earlier on, before the corrected headers. The
+result is that you get the uncorrected header files.
+
+Instead, you should use these options (when compiling C programs):
+
+@smallexample
+-I/usr/local/lib/gcc-lib/@var{target}/@var{version}/include -I/usr/include
+@end smallexample
+
+For C++ programs, GNU CC also uses a special directory that defines C++
+interfaces to standard C subroutines. This directory is meant to be
+searched @emph{before} other standard include directories, so that it
+takes precedence. If you are compiling C++ programs and specifying
+include directories explicitly, use this option first, then the two
+options above:
+
+@example
+-I/usr/local/lib/g++-include
+@end example
+
+@ignore
+@cindex @code{vfork}, for the Sun-4
+@item
+There is a bug in @code{vfork} on the Sun-4 which causes the registers
+of the child process to clobber those of the parent. Because of this,
+programs that call @code{vfork} are likely to lose when compiled
+optimized with GNU CC when the child code alters registers which contain
+C variables in the parent. This affects variables which are live in the
+parent across the call to @code{vfork}.
+
+If you encounter this, you can work around the problem by declaring
+variables @code{volatile} in the function that calls @code{vfork}, until
+the problem goes away, or by not declaring them @code{register} and not
+using @samp{-O} for those source files.
+@end ignore
+
+@item
+On some SGI systems, when you use @samp{-lgl_s} as an option,
+it gets translated magically to @samp{-lgl_s -lX11_s -lc_s}.
+Naturally, this does not happen when you use GNU CC.
+You must specify all three options explicitly.
+
+@item
+On a Sparc, GNU CC aligns all values of type @code{double} on an 8-byte
+boundary, and it expects every @code{double} to be so aligned. The Sun
+compiler usually gives @code{double} values 8-byte alignment, with one
+exception: function arguments of type @code{double} may not be aligned.
+
+As a result, if a function compiled with Sun CC takes the address of an
+argument of type @code{double} and passes this pointer of type
+@code{double *} to a function compiled with GNU CC, dereferencing the
+pointer may cause a fatal signal.
+
+One way to solve this problem is to compile your entire program with GNU
+CC. Another solution is to modify the function that is compiled with
+Sun CC to copy the argument into a local variable; local variables
+are always properly aligned. A third solution is to modify the function
+that uses the pointer to dereference it via the following function
+@code{access_double} instead of directly with @samp{*}:
+
+@smallexample
+inline double
+access_double (double *unaligned_ptr)
+@{
+ union d2i @{ double d; int i[2]; @};
+
+ union d2i *p = (union d2i *) unaligned_ptr;
+ union d2i u;
+
+ u.i[0] = p->i[0];
+ u.i[1] = p->i[1];
+
+ return u.d;
+@}
+@end smallexample
+
+@noindent
+Storing into the pointer can be done likewise with the same union.
+
+@item
+On Solaris, the @code{malloc} function in the @file{libmalloc.a} library
+may allocate memory that is only 4 byte aligned. Since GNU CC on the
+Sparc assumes that doubles are 8 byte aligned, this may result in a
+fatal signal if doubles are stored in memory allocated by the
+@file{libmalloc.a} library.
+
+The solution is to not use the @file{libmalloc.a} library. Use instead
+@code{malloc} and related functions from @file{libc.a}; they do not have
+this problem.
+
+@item
+Sun forgot to include a static version of @file{libdl.a} with some
+versions of SunOS (mainly 4.1). This results in undefined symbols when
+linking static binaries (that is, if you use @samp{-static}). If you
+see undefined symbols @code{_dlclose}, @code{_dlsym} or @code{_dlopen}
+when linking, compile and link against the file
+@file{mit/util/misc/dlsym.c} from the MIT version of X windows.
+
+@item
+The 128-bit long double format that the Sparc port supports currently
+works by using the architecturally defined quad-word floating point
+instructions. Since there is no hardware that supports these
+instructions they must be emulated by the operating system. Long
+doubles do not work in Sun OS versions 4.0.3 and earlier, because the
+kernel emulator uses an obsolete and incompatible format. Long doubles
+do not work in Sun OS version 4.1.1 due to a problem in a Sun library.
+Long doubles do work on Sun OS versions 4.1.2 and higher, but GNU CC
+does not enable them by default. Long doubles appear to work in Sun OS
+5.x (Solaris 2.x).
+
+@item
+On HP-UX version 9.01 on the HP PA, the HP compiler @code{cc} does not
+compile GNU CC correctly. We do not yet know why. However, GNU CC
+compiled on earlier HP-UX versions works properly on HP-UX 9.01 and can
+compile itself properly on 9.01.
+
+@item
+On the HP PA machine, ADB sometimes fails to work on functions compiled
+with GNU CC. Specifically, it fails to work on functions that use
+@code{alloca} or variable-size arrays. This is because GNU CC doesn't
+generate HP-UX unwind descriptors for such functions. It may even be
+impossible to generate them.
+
+@item
+Debugging (@samp{-g}) is not supported on the HP PA machine, unless you use
+the preliminary GNU tools (@pxref{Installation}).
+
+@item
+Taking the address of a label may generate errors from the HP-UX
+PA assembler. GAS for the PA does not have this problem.
+
+@item
+Using floating point parameters for indirect calls to static functions
+will not work when using the HP assembler. There simply is no way for GCC
+to specify what registers hold arguments for static functions when using
+the HP assembler. GAS for the PA does not have this problem.
+
+@item
+In extremely rare cases involving some very large functions you may
+receive errors from the HP linker complaining about an out of bounds
+unconditional branch offset. This used to occur more often in previous
+versions of GNU CC, but is now exceptionally rare. If you should run
+into it, you can work around by making your function smaller.
+
+@item
+GNU CC compiled code sometimes emits warnings from the HP-UX assembler of
+the form:
+
+@smallexample
+(warning) Use of GR3 when
+ frame >= 8192 may cause conflict.
+@end smallexample
+
+These warnings are harmless and can be safely ignored.
+
+@item
+The current version of the assembler (@file{/bin/as}) for the RS/6000
+has certain problems that prevent the @samp{-g} option in GCC from
+working. Note that @file{Makefile.in} uses @samp{-g} by default when
+compiling @file{libgcc2.c}.
+
+IBM has produced a fixed version of the assembler. The upgraded
+assembler unfortunately was not included in any of the AIX 3.2 update
+PTF releases (3.2.2, 3.2.3, or 3.2.3e). Users of AIX 3.1 should request
+PTF U403044 from IBM and users of AIX 3.2 should request PTF U416277.
+See the file @file{README.RS6000} for more details on these updates.
+
+You can test for the presense of a fixed assembler by using the
+command
+
+@smallexample
+as -u < /dev/null
+@end smallexample
+
+@noindent
+If the command exits normally, the assembler fix already is installed.
+If the assembler complains that "-u" is an unknown flag, you need to
+order the fix.
+
+@item
+On the IBM RS/6000, compiling code of the form
+
+@smallexample
+extern int foo;
+
+@dots{} foo @dots{}
+
+static int foo;
+@end smallexample
+
+@noindent
+will cause the linker to report an undefined symbol @code{foo}.
+Although this behavior differs from most other systems, it is not a
+bug because redefining an @code{extern} variable as @code{static}
+is undefined in ANSI C.
+
+@item
+AIX on the RS/6000 provides support (NLS) for environments outside of
+the United States. Compilers and assemblers use NLS to support
+locale-specific representations of various objects including
+floating-point numbers ("." vs "," for separating decimal fractions).
+There have been problems reported where the library linked with GCC does
+not produce the same floating-point formats that the assembler accepts.
+If you have this problem, set the LANG environment variable to "C" or
+"En_US".
+
+@item
+Even if you specify @samp{-fdollars-in-identifiers},
+you cannot successfully use @samp{$} in identifiers on the RS/6000 due
+to a restriction in the IBM assembler. GAS supports these
+identifiers.
+
+@item
+On the RS/6000, XLC version 1.3.0.0 will miscompile @file{jump.c}. XLC
+version 1.3.0.1 or later fixes this problem. You can obtain XLC-1.3.0.2
+by requesting PTF 421749 from IBM.
+
+@item
+There is an assembler bug in versions of DG/UX prior to 5.4.2.01 that
+occurs when the @samp{fldcr} instruction is used. GNU CC uses
+@samp{fldcr} on the 88100 to serialize volatile memory references. Use
+the option @samp{-mno-serialize-volatile} if your version of the
+assembler has this bug.
+
+@item
+On VMS, GAS versions 1.38.1 and earlier may cause spurious warning
+messages from the linker. These warning messages complain of mismatched
+psect attributes. You can ignore them. @xref{VMS Install}.
+
+@item
+On NewsOS version 3, if you include both of the files @file{stddef.h}
+and @file{sys/types.h}, you get an error because there are two typedefs
+of @code{size_t}. You should change @file{sys/types.h} by adding these
+lines around the definition of @code{size_t}:
+
+@smallexample
+#ifndef _SIZE_T

+@var{actual typedef here}
+#endif
+@end smallexample
+
+@cindex Alliant

+and unions is unusual, and is not compatible with GNU CC no matter
+what options are used.
+
+@cindex RT PC
+@cindex IBM RT PC
+@item
+On the IBM RT PC, the MetaWare HighC compiler (hc) uses a different
+convention for structure and union returning. Use the option
+@samp{-mhc-struct-return} to tell GNU CC to use a convention compatible
+with it.
+
+@cindex Vax calling convention
+@cindex Ultrix calling convention
+@item
+On Ultrix, the Fortran compiler expects registers 2 through 5 to be saved
+by function calls. However, the C compiler uses conventions compatible
+with BSD Unix: registers 2 through 5 may be clobbered by function calls.
+
+GNU CC uses the same convention as the Ultrix C compiler. You can use
+these options to produce code compatible with the Fortran compiler:
+
+@smallexample
+-fcall-saved-r2 -fcall-saved-r3 -fcall-saved-r4 -fcall-saved-r5
+@end smallexample
+
+@item
+On the WE32k, you may find that programs compiled with GNU CC do not
+work with the standard shared C library. You may need to link with
+the ordinary C compiler. If you do so, you must specify the following
+options:
+
+@smallexample
+-L/usr/local/lib/gcc-lib/we32k-att-sysv/2.7.1 -lgcc -lc_s
+@end smallexample
+
+The first specifies where to find the library @file{libgcc.a}
+specified with the @samp{-lgcc} option.
+
+GNU CC does linking by invoking @code{ld}, just as @code{cc} does, and
+there is no reason why it @emph{should} matter which compilation program
+you use to invoke @code{ld}. If someone tracks this problem down,
+it can probably be fixed easily.
+
+@item
+On the Alpha, you may get assembler errors about invalid syntax as a
+result of floating point constants. This is due to a bug in the C
+library functions @code{ecvt}, @code{fcvt} and @code{gcvt}. Given valid
+floating point numbers, they sometimes print @samp{NaN}.
+
+@item
+On Irix 4.0.5F (and perhaps in some other versions), an assembler bug
+sometimes reorders instructions incorrectly when optimization is turned
+on. If you think this may be happening to you, try using the GNU
+assembler; GAS version 2.1 supports ECOFF on Irix.
+
+Or use the @samp{-noasmopt} option when you compile GNU CC with itself,
+and then again when you compile your program. (This is a temporary
+kludge to turn off assembler optimization on Irix.) If this proves to
+be what you need, edit the assembler spec in the file @file{specs} so
+that it unconditionally passes @samp{-O0} to the assembler, and never
+passes @samp{-O2} or @samp{-O3}.

+most of which are unnecessary with GCC 2.4.5 and newer versions. You
+can make a properly working Perl by setting @code{ccflags} to
+@samp{-fwritable-strings} (implied by the @samp{-traditional} in the
+original options) and @code{cppflags} to empty in @file{config.sh}, then

+On various 386 Unix systems derived from System V, including SCO, ISC,
+and ESIX, you may get error messages about running out of virtual memory
+while compiling certain programs.
+
+You can prevent this problem by linking GNU CC with the GNU malloc
+(which thus replaces the malloc that comes with the system). GNU malloc
+is available as a separate package, and also in the file
+@file{src/gmalloc.c} in the GNU Emacs 19 distribution.
+
+If you have installed GNU malloc as a separate library package, use this
+option when you relink GNU CC:
+
+@example
+MALLOC=/usr/local/lib/libgmalloc.a

+
+Alternatively, if you have compiled @file{gmalloc.c} from Emacs 19, copy
+the object file to @file{gmalloc.o} and use this option when you relink
+GNU CC:

+@node Incompatibilities
+@section Incompatibilities of GNU CC
+@cindex incompatibilities of GNU CC
+
+There are several noteworthy incompatibilities between GNU C and most
+existing (non-ANSI) versions of C. The @samp{-traditional} option
+eliminates many of these incompatibilities, @emph{but not all}, by
+telling GNU C to behave like the other C compilers.
+
+@itemize @bullet
+@cindex string constants
+@cindex read-only strings
+@cindex shared strings
+@item
+GNU CC normally makes string constants read-only. If several
+identical-looking string constants are used, GNU CC stores only one
+copy of the string.
+
+@cindex @code{mktemp}, and constant strings
+One consequence is that you cannot call @code{mktemp} with a string
+constant argument. The function @code{mktemp} always alters the
+string its argument points to.
+
+@cindex @code{sscanf}, and constant strings
+@cindex @code{fscanf}, and constant strings
+@cindex @code{scanf}, and constant strings
+Another consequence is that @code{sscanf} does not work on some systems
+when passed a string constant as its format control string or input.
+This is because @code{sscanf} incorrectly tries to write into the string
+constant. Likewise @code{fscanf} and @code{scanf}.
+
+The best solution to these problems is to change the program to use
+@code{char}-array variables with initialization strings for these
+purposes instead of string constants. But if this is not possible,
+you can use the @samp{-fwritable-strings} flag, which directs GNU CC
+to handle string constants the same way most C compilers do.
+@samp{-traditional} also has this effect, among others.
+
+@item
+@code{-2147483648} is positive.
+
+This is because 2147483648 cannot fit in the type @code{int}, so
+(following the ANSI C rules) its data type is @code{unsigned long int}.
+Negating this value yields 2147483648 again.
+
+@item
+GNU CC does not substitute macro arguments when they appear inside of
+string constants. For example, the following macro in GNU CC
+
+@example
+#define foo(a) "a"
+@end example
+
+@noindent
+will produce output @code{"a"} regardless of what the argument @var{a} is.
+
+The @samp{-traditional} option directs GNU CC to handle such cases
+(among others) in the old-fashioned (non-ANSI) fashion.
+
+@cindex @code{setjmp} incompatibilities
+@cindex @code{longjmp} incompatibilities
+@item
+When you use @code{setjmp} and @code{longjmp}, the only automatic
+variables guaranteed to remain valid are those declared
+@code{volatile}. This is a consequence of automatic register
+allocation. Consider this function:
+
+@example
+jmp_buf j;
+
+foo ()
+@{
+ int a, b;
+
+ a = fun1 ();
+ if (setjmp (j))
+ return a;
+
+ a = fun2 ();
+ /* @r{@code{longjmp (j)} may occur in @code{fun3}.} */
+ return a + fun3 ();
+@}
+@end example
+
+Here @code{a} may or may not be restored to its first value when the
+@code{longjmp} occurs. If @code{a} is allocated in a register, then
+its first value is restored; otherwise, it keeps the last value stored
+in it.
+
+If you use the @samp{-W} option with the @samp{-O} option, you will
+get a warning when GNU CC thinks such a problem might be possible.
+
+The @samp{-traditional} option directs GNU C to put variables in
+the stack by default, rather than in registers, in functions that
+call @code{setjmp}. This results in the behavior found in
+traditional C compilers.
+
+@item
+Programs that use preprocessing directives in the middle of macro
+arguments do not work with GNU CC. For example, a program like this
+will not work:
+
+@example
+foobar (
+#define luser
+ hack)
+@end example
+
+ANSI C does not permit such a construct. It would make sense to support
+it when @samp{-traditional} is used, but it is too much work to
+implement.
+
+@cindex external declaration scope
+@cindex scope of external declarations
+@cindex declaration scope
+@item
+Declarations of external variables and functions within a block apply
+only to the block containing the declaration. In other words, they
+have the same scope as any other declaration in the same place.
+
+In some other C compilers, a @code{extern} declaration affects all the
+rest of the file even if it happens within a block.
+
+The @samp{-traditional} option directs GNU C to treat all @code{extern}
+declarations as global, like traditional compilers.
+
+@item
+In traditional C, you can combine @code{long}, etc., with a typedef name,
+as shown here:
+
+@example
+typedef int foo;
+typedef long foo bar;
+@end example
+
+In ANSI C, this is not allowed: @code{long} and other type modifiers
+require an explicit @code{int}. Because this criterion is expressed
+by Bison grammar rules rather than C code, the @samp{-traditional}
+flag cannot alter it.
+
+@cindex typedef names as function parameters
+@item
+PCC allows typedef names to be used as function parameters. The
+difficulty described immediately above applies here too.
+
+@cindex whitespace
+@item
+PCC allows whitespace in the middle of compound assignment operators
+such as @samp{+=}. GNU CC, following the ANSI standard, does not
+allow this. The difficulty described immediately above applies here
+too.
+
+@cindex apostrophes
+@cindex '
+@item
+GNU CC complains about unterminated character constants inside of
+preprocessing conditionals that fail. Some programs have English
+comments enclosed in conditionals that are guaranteed to fail; if these
+comments contain apostrophes, GNU CC will probably report an error. For
+example, this code would produce an error:
+
+@example
+#if 0
+You can't expect this to work.
+#endif
+@end example
+
+The best solution to such a problem is to put the text into an actual
+C comment delimited by @samp{/*@dots{}*/}. However,
+@samp{-traditional} suppresses these error messages.
+
+@item
+Many user programs contain the declaration @samp{long time ();}. In the
+past, the system header files on many systems did not actually declare
+@code{time}, so it did not matter what type your program declared it to
+return. But in systems with ANSI C headers, @code{time} is declared to
+return @code{time_t}, and if that is not the same as @code{long}, then
+@samp{long time ();} is erroneous.
+
+The solution is to change your program to use @code{time_t} as the return
+type of @code{time}.
+
+@cindex @code{float} as function value type
+@item
+When compiling functions that return @code{float}, PCC converts it to
+a double. GNU CC actually returns a @code{float}. If you are concerned
+with PCC compatibility, you should declare your functions to return
+@code{double}; you might as well say what you mean.
+
+@cindex structures
+@cindex unions
+@item
+When compiling functions that return structures or unions, GNU CC
+output code normally uses a method different from that used on most
+versions of Unix. As a result, code compiled with GNU CC cannot call
+a structure-returning function compiled with PCC, and vice versa.
+
+The method used by GNU CC is as follows: a structure or union which is
+1, 2, 4 or 8 bytes long is returned like a scalar. A structure or union
+with any other size is stored into an address supplied by the caller
+(usually in a special, fixed register, but on some machines it is passed
+on the stack). The machine-description macros @code{STRUCT_VALUE} and
+@code{STRUCT_INCOMING_VALUE} tell GNU CC where to pass this address.
+
+By contrast, PCC on most target machines returns structures and unions
+of any size by copying the data into an area of static storage, and then
+returning the address of that storage as if it were a pointer value.
+The caller must copy the data from that memory area to the place where
+the value is wanted. GNU CC does not use this method because it is
+slower and nonreentrant.
+
+On some newer machines, PCC uses a reentrant convention for all
+structure and union returning. GNU CC on most of these machines uses a
+compatible convention when returning structures and unions in memory,
+but still returns small structures and unions in registers.
+
+You can tell GNU CC to use a compatible convention for all structure and
+union returning with the option @samp{-fpcc-struct-return}.
+
+@cindex preprocessing tokens
+@cindex preprocessing numbers
+@item
+GNU C complains about program fragments such as @samp{0x74ae-0x4000}
+which appear to be two hexadecimal constants separated by the minus
+operator. Actually, this string is a single @dfn{preprocessing token}.
+Each such token must correspond to one token in C. Since this does not,
+GNU C prints an error message. Although it may appear obvious that what
+is meant is an operator and two values, the ANSI C standard specifically
+requires that this be treated as erroneous.
+
+A @dfn{preprocessing token} is a @dfn{preprocessing number} if it
+begins with a digit and is followed by letters, underscores, digits,
+periods and @samp{e+}, @samp{e-}, @samp{E+}, or @samp{E-} character
+sequences.
+
+To make the above program fragment valid, place whitespace in front of
+the minus sign. This whitespace will end the preprocessing number.
+@end itemize
+
+@node Fixed Headers
+@section Fixed Header Files
+
+GNU CC needs to install corrected versions of some system header files.
+This is because most target systems have some header files that won't
+work with GNU CC unless they are changed. Some have bugs, some are
+incompatible with ANSI C, and some depend on special features of other
+compilers.
+
+Installing GNU CC automatically creates and installs the fixed header
+files, by running a program called @code{fixincludes} (or for certain
+targets an alternative such as @code{fixinc.svr4}). Normally, you
+don't need to pay attention to this. But there are cases where it
+doesn't do the right thing automatically.
+
+@itemize @bullet
+@item
+If you update the system's header files, such as by installing a new
+system version, the fixed header files of GNU CC are not automatically
+updated. The easiest way to update them is to reinstall GNU CC. (If
+you want to be clever, look in the makefile and you can find a
+shortcut.)
+
+@item
+On some systems, in particular SunOS 4, header file directories contain
+machine-specific symbolic links in certain places. This makes it
+possible to share most of the header files among hosts running the
+same version of SunOS 4 on different machine models.
+
+The programs that fix the header files do not understand this special
+way of using symbolic links; therefore, the directory of fixed header
+files is good only for the machine model used to build it.
+
+In SunOS 4, only programs that look inside the kernel will notice the
+difference between machine models. Therefore, for most purposes, you
+need not be concerned about this.
+
+It is possible to make separate sets of fixed header files for the
+different machine models, and arrange a structure of symbolic links so
+as to use the proper set, but you'll have to do this by hand.
+
+@item
+On Lynxos, GNU CC by default does not fix the header files. This is
+because bugs in the shell cause the @code{fixincludes} script to fail.
+
+This means you will encounter problems due to bugs in the system header
+files. It may be no comfort that they aren't GNU CC's fault, but it
+does mean that there's nothing for us to do about them.
+@end itemize
+
+@node Standard Libraries
+@section Standard Libraries
+
+GNU CC by itself attempts to be what the ISO/ANSI C standard calls a
+@dfn{conforming freestanding implementation}. This means all ANSI
+C language features are available, as well as the contents of
+@file{float.h}, @file{limits.h}, @file{stdarg.h}, and
+@file{stddef.h}. The rest of the C library is supplied by the
+vendor of the operating system. If that C library doesn't conform to
+the C standards, then your programs might get warnings (especially when
+using @samp{-Wall}) that you don't expect.
+
+For example, the @code{sprintf} function on SunOS 4.1.3 returns
+@code{char *} while the C standard says that @code{sprintf} returns an
+@code{int}. The @code{fixincludes} program could make the prototype for
+this function match the Standard, but that would be wrong, since the
+function will still return @code{char *}.
+
+If you need a Standard compliant library, then you need to find one, as
+GNU CC does not provide one. The GNU C library (called @code{glibc})
+has been ported to a number of operating systems, and provides ANSI/ISO,
+POSIX, BSD and SystemV compatibility. You could also ask your operating
+system vendor if newer libraries are available.
+
+@node Disappointments
+@section Disappointments and Misunderstandings
+
+These problems are perhaps regrettable, but we don't know any practical
+way around them.
+
+@itemize @bullet
+@item
+Certain local variables aren't recognized by debuggers when you compile
+with optimization.
+
+This occurs because sometimes GNU CC optimizes the variable out of
+existence. There is no way to tell the debugger how to compute the
+value such a variable ``would have had'', and it is not clear that would
+be desirable anyway. So GNU CC simply does not mention the eliminated
+variable when it writes debugging information.
+
+You have to expect a certain amount of disagreement between the
+executable and your source code, when you use optimization.
+
+@cindex conflicting types
+@cindex scope of declaration
+@item
+Users often think it is a bug when GNU CC reports an error for code
+like this:
+
+@example
+int foo (struct mumble *);
+
+struct mumble @{ @dots{} @};
+
+int foo (struct mumble *x)
+@{ @dots{} @}
+@end example
+
+This code really is erroneous, because the scope of @code{struct
+mumble} in the prototype is limited to the argument list containing it.
+It does not refer to the @code{struct mumble} defined with file scope
+immediately below---they are two unrelated types with similar names in
+different scopes.
+
+But in the definition of @code{foo}, the file-scope type is used
+because that is available to be inherited. Thus, the definition and
+the prototype do not match, and you get an error.
+
+This behavior may seem silly, but it's what the ANSI standard specifies.
+It is easy enough for you to make your code work by moving the
+definition of @code{struct mumble} above the prototype. It's not worth
+being incompatible with ANSI C just to avoid an error for the example
+shown above.
+
+@item
+Accesses to bitfields even in volatile objects works by accessing larger
+objects, such as a byte or a word. You cannot rely on what size of
+object is accessed in order to read or write the bitfield; it may even
+vary for a given bitfield according to the precise usage.
+
+If you care about controlling the amount of memory that is accessed, use
+volatile but do not use bitfields.
+
+@item
+GNU CC comes with shell scripts to fix certain known problems in system
+header files. They install corrected copies of various header files in
+a special directory where only GNU CC will normally look for them. The
+scripts adapt to various systems by searching all the system header
+files for the problem cases that we know about.
+
+If new system header files are installed, nothing automatically arranges
+to update the corrected header files. You will have to reinstall GNU CC
+to fix the new header files. More specifically, go to the build
+directory and delete the files @file{stmp-fixinc} and
+@file{stmp-headers}, and the subdirectory @code{include}; then do
+@samp{make install} again.
+
+@item
+@cindex floating point precision
+On 68000 and x86 systems, for instance, you can get paradoxical results
+if you test the precise values of floating point numbers. For example,
+you can find that a floating point value which is not a NaN is not equal
+to itself. This results from the fact that the floating point registers
+hold a few more bits of precision than fit in a @code{double} in memory.
+Compiled code moves values between memory and floating point registers
+at its convenience, and moving them into memory truncates them.
+
+You can partially avoid this problem by using the @samp{-ffloat-store}
+option (@pxref{Optimize Options}).
+
+@item
+On the MIPS, variable argument functions using @file{varargs.h}
+cannot have a floating point value for the first argument. The
+reason for this is that in the absence of a prototype in scope,
+if the first argument is a floating point, it is passed in a
+floating point register, rather than an integer register.
+
+If the code is rewritten to use the ANSI standard @file{stdarg.h}
+method of variable arguments, and the prototype is in scope at
+the time of the call, everything will work fine.
+
+@item
+On the H8/300 and H8/300H, variable argument functions must be
+implemented using the ANSI standard @file{stdarg.h} method of
+variable arguments. Furthermore, calls to functions using @file{stdarg.h}
+variable arguments must have a prototype for the called function
+in scope at the time of the call.

+@cindex misunderstandings in C++
+@cindex surprises in C++
+@cindex C++ misunderstandings
+C++ is a complex language and an evolving one, and its standard definition
+(the ANSI C++ draft standard) is also evolving. As a result,
+your C++ compiler may occasionally surprise you, even when its behavior is
+correct. This section discusses some areas that frequently give rise to
+questions of this sort.
+
+@menu
+* Static Definitions:: Static member declarations are not definitions

+
+@node Static Definitions
+@subsection Declare @emph{and} Define Static Members
+
+@cindex C++ static data, declaring and defining
+@cindex static data in C++, declaring and defining
+@cindex declaring static data in C++
+@cindex defining static data in C++
+When a class has static data members, it is not enough to @emph{declare}
+the static member; you must also @emph{define} it. For example:
+
+@example
+class Foo
+@{
+ @dots{}
+ void method();
+ static int bar;
+@};
+@end example
+
+This declaration only establishes that the class @code{Foo} has an
+@code{int} named @code{Foo::bar}, and a member function named
+@code{Foo::method}. But you still need to define @emph{both}
+@code{method} and @code{bar} elsewhere. According to the draft ANSI
+standard, you must supply an initializer in one (and only one) source
+file, such as:
+
+@example
+int Foo::bar = 0;
+@end example
+
+Other C++ compilers may not correctly implement the standard behavior.
+As a result, when you switch to @code{g++} from one of these compilers,
+you may discover that a program that appeared to work correctly in fact
+does not conform to the standard: @code{g++} reports as undefined
+symbols any static data members that lack definitions.
+
+@node Temporaries
+@subsection Temporaries May Vanish Before You Expect
+
+@cindex temporaries, lifetime of
+@cindex portions of temporary objects, pointers to
+It is dangerous to use pointers or references to @emph{portions} of a
+temporary object. The compiler may very well delete the object before
+you expect it to, leaving a pointer to garbage. The most common place
+where this problem crops up is in classes like the libg++
+@code{String} class, that define a conversion function to type
+@code{char *} or @code{const char *}. However, any class that returns
+a pointer to some internal structure is potentially subject to this
+problem.
+
+For example, a program may use a function @code{strfunc} that returns
+@code{String} objects, and another function @code{charfunc} that
+operates on pointers to @code{char}:
+
+@example
+String strfunc ();
+void charfunc (const char *);
+@end example
+
+@noindent
+In this situation, it may seem natural to write @w{@samp{charfunc
+(strfunc ());}} based on the knowledge that class @code{String} has an
+explicit conversion to @code{char} pointers. However, what really
+happens is akin to @samp{charfunc (@w{strfunc ()}.@w{convert ()});},
+where the @code{convert} method is a function to do the same data
+conversion normally performed by a cast. Since the last use of the
+temporary @code{String} object is the call to the conversion function,
+the compiler may delete that object before actually calling
+@code{charfunc}. The compiler has no way of knowing that deleting the
+@code{String} object will invalidate the pointer. The pointer then
+points to garbage, so that by the time @code{charfunc} is called, it
+gets an invalid argument.
+
+Code like this may run successfully under some other compilers,
+especially those that delete temporaries relatively late. However, the
+GNU C++ behavior is also standard-conforming, so if your program depends
+on late destruction of temporaries it is not portable.
+
+If you think this is surprising, you should be aware that the ANSI C++
+committee continues to debate the lifetime-of-temporaries problem.
+
+For now, at least, the safe way to write such code is to give the
+temporary a name, which forces it to remain until the end of the scope of
+the name. For example:
+
+@example
+String& tmp = strfunc ();
+charfunc (tmp);
+@end example
+
+@node Protoize Caveats
+@section Caveats of using @code{protoize}
+
+The conversion programs @code{protoize} and @code{unprotoize} can
+sometimes change a source file in a way that won't work unless you
+rearrange it.
+
+@itemize @bullet
+@item
+@code{protoize} can insert references to a type name or type tag before
+the definition, or in a file where they are not defined.
+
+If this happens, compiler error messages should show you where the new
+references are, so fixing the file by hand is straightforward.
+
+@item
+There are some C constructs which @code{protoize} cannot figure out.
+For example, it can't determine argument types for declaring a
+pointer-to-function variable; this you must do by hand. @code{protoize}
+inserts a comment containing @samp{???} each time it finds such a
+variable; so you can find all such variables by searching for this
+string. ANSI C does not require declaring the argument types of
+pointer-to-function types.
+
+@item
+Using @code{unprotoize} can easily introduce bugs. If the program
+relied on prototypes to bring about conversion of arguments, these
+conversions will not take place in the program without prototypes.
+One case in which you can be sure @code{unprotoize} is safe is when
+you are removing prototypes that were made with @code{protoize}; if
+the program worked before without any prototypes, it will work again
+without them.
+
+You can find all the places where this problem might occur by compiling
+the program with the @samp{-Wconversion} option. It prints a warning
+whenever an argument is converted.
+
+@item
+Both conversion programs can be confused if there are macro calls in and
+around the text to be converted. In other words, the standard syntax
+for a declaration or definition must not result from expanding a macro.
+This problem is inherent in the design of C and cannot be fixed. If
+only a few functions have confusing macro calls, you can easily convert
+them manually.
+
+@item
+@code{protoize} cannot get the argument types for a function whose
+definition was not actually compiled due to preprocessing conditionals.
+When this happens, @code{protoize} changes nothing in regard to such
+a function. @code{protoize} tries to detect such instances and warn
+about them.
+
+You can generally work around this problem by using @code{protoize} step
+by step, each time specifying a different set of @samp{-D} options for
+compilation, until all of the functions have been converted. There is
+no automatic way to verify that you have got them all, however.
+
+@item
+Confusion may result if there is an occasion to convert a function
+declaration or definition in a region of source code where there is more
+than one formal parameter list present. Thus, attempts to convert code
+containing multiple (conditionally compiled) versions of a single
+function header (in the same vicinity) may not produce the desired (or
+expected) results.
+
+If you plan on converting source files which contain such code, it is
+recommended that you first make sure that each conditionally compiled
+region of source code which contains an alternative function header also
+contains at least one additional follower token (past the final right
+parenthesis of the function header). This should circumvent the
+problem.
+
+@item
+@code{unprotoize} can become confused when trying to convert a function
+definition or declaration which contains a declaration for a
+pointer-to-function formal argument which has the same name as the
+function being defined or declared. We recommand you avoid such choices
+of formal parameter names.
+
+@item
+You might also want to correct some of the indentation by hand and break
+long lines. (The conversion programs don't write lines longer than
+eighty characters in any case.)

+
+@node Non-bugs
+@section Certain Changes We Don't Want to Make
+
+This section lists changes that people frequently request, but which
+we do not make because we think GNU CC is better without them.
+
+@itemize @bullet
+@item
+Checking the number and type of arguments to a function which has an
+old-fashioned definition and no prototype.
+
+Such a feature would work only occasionally---only for calls that appear
+in the same file as the called function, following the definition. The
+only way to check all calls reliably is to add a prototype for the
+function. But adding a prototype eliminates the motivation for this
+feature. So the feature is not worthwhile.
+
+@item
+Warning about using an expression whose type is signed as a shift count.
+
+Shift count operands are probably signed more often than unsigned.
+Warning about this would cause far more annoyance than good.
+
+@item
+Warning about assigning a signed value to an unsigned variable.
+
+Such assignments must be very common; warning about them would cause
+more annoyance than good.
+
+@item
+Warning about unreachable code.
+
+It's very common to have unreachable code in machine-generated
+programs. For example, this happens normally in some files of GNU C
+itself.
+
+@item
+Warning when a non-void function value is ignored.
+
+Coming as I do from a Lisp background, I balk at the idea that there is
+something dangerous about discarding a value. There are functions that
+return values which some callers may find useful; it makes no sense to
+clutter the program with a cast to @code{void} whenever the value isn't
+useful.
+
+@item
+Assuming (for optimization) that the address of an external symbol is
+never zero.
+
+This assumption is false on certain systems when @samp{#pragma weak} is
+used.
+
+@item
+Making @samp{-fshort-enums} the default.
+
+This would cause storage layout to be incompatible with most other C
+compilers. And it doesn't seem very important, given that you can get
+the same result in other ways. The case where it matters most is when
+the enumeration-valued object is inside a structure, and in that case
+you can specify a field width explicitly.
+
+@item
+Making bitfields unsigned by default on particular machines where ``the
+ABI standard'' says to do so.
+
+The ANSI C standard leaves it up to the implementation whether a bitfield
+declared plain @code{int} is signed or not. This in effect creates two
+alternative dialects of C.
+
+The GNU C compiler supports both dialects; you can specify the signed
+dialect with @samp{-fsigned-bitfields} and the unsigned dialect with
+@samp{-funsigned-bitfields}. However, this leaves open the question of
+which dialect to use by default.
+
+Currently, the preferred dialect makes plain bitfields signed, because
+this is simplest. Since @code{int} is the same as @code{signed int} in
+every other context, it is cleanest for them to be the same in bitfields
+as well.
+
+Some computer manufacturers have published Application Binary Interface
+standards which specify that plain bitfields should be unsigned. It is
+a mistake, however, to say anything about this issue in an ABI. This is
+because the handling of plain bitfields distinguishes two dialects of C.
+Both dialects are meaningful on every type of machine. Whether a
+particular object file was compiled using signed bitfields or unsigned
+is of no concern to other object files, even if they access the same
+bitfields in the same data structures.
+
+A given program is written in one or the other of these two dialects.
+The program stands a chance to work on most any machine if it is
+compiled with the proper dialect. It is unlikely to work at all if
+compiled with the wrong dialect.
+
+Many users appreciate the GNU C compiler because it provides an
+environment that is uniform across machines. These users would be
+inconvenienced if the compiler treated plain bitfields differently on
+certain machines.
+
+Occasionally users write programs intended only for a particular machine
+type. On these occasions, the users would benefit if the GNU C compiler
+were to support by default the same dialect as the other compilers on
+that machine. But such applications are rare. And users writing a
+program to run on more than one type of machine cannot possibly benefit
+from this kind of compatibility.
+
+This is why GNU CC does and will treat plain bitfields in the same
+fashion on all types of machines (by default).
+
+There are some arguments for making bitfields unsigned by default on all
+machines. If, for example, this becomes a universal de facto standard,
+it would make sense for GNU CC to go along with it. This is something
+to be considered in the future.
+
+(Of course, users strongly concerned about portability should indicate
+explicitly in each bitfield whether it is signed or not. In this way,
+they write programs which have the same meaning in both C dialects.)
+
+@item
+Undefining @code{__STDC__} when @samp{-ansi} is not used.
+
+Currently, GNU CC defines @code{__STDC__} as long as you don't use
+@samp{-traditional}. This provides good results in practice.
+
+Programmers normally use conditionals on @code{__STDC__} to ask whether
+it is safe to use certain features of ANSI C, such as function
+prototypes or ANSI token concatenation. Since plain @samp{gcc} supports
+all the features of ANSI C, the correct answer to these questions is
+``yes''.
+
+Some users try to use @code{__STDC__} to check for the availability of
+certain library facilities. This is actually incorrect usage in an ANSI
+C program, because the ANSI C standard says that a conforming
+freestanding implementation should define @code{__STDC__} even though it
+does not have the library facilities. @samp{gcc -ansi -pedantic} is a
+conforming freestanding implementation, and it is therefore required to
+define @code{__STDC__}, even though it does not come with an ANSI C
+library.
+
+Sometimes people say that defining @code{__STDC__} in a compiler that
+does not completely conform to the ANSI C standard somehow violates the
+standard. This is illogical. The standard is a standard for compilers
+that claim to support ANSI C, such as @samp{gcc -ansi}---not for other
+compilers such as plain @samp{gcc}. Whatever the ANSI C standard says
+is relevant to the design of plain @samp{gcc} without @samp{-ansi} only
+for pragmatic reasons, not as a requirement.
+
+@item
+Undefining @code{__STDC__} in C++.
+
+Programs written to compile with C++-to-C translators get the
+value of @code{__STDC__} that goes with the C compiler that is
+subsequently used. These programs must test @code{__STDC__}
+to determine what kind of C preprocessor that compiler uses:
+whether they should concatenate tokens in the ANSI C fashion
+or in the traditional fashion.
+
+These programs work properly with GNU C++ if @code{__STDC__} is defined.
+They would not work otherwise.
+
+In addition, many header files are written to provide prototypes in ANSI
+C but not in traditional C. Many of these header files can work without
+change in C++ provided @code{__STDC__} is defined. If @code{__STDC__}
+is not defined, they will all fail, and will all need to be changed to
+test explicitly for C++ as well.
+
+@item
+Deleting ``empty'' loops.
+
+GNU CC does not delete ``empty'' loops because the most likely reason
+you would put one in a program is to have a delay. Deleting them will
+not make real programs run any faster, so it would be pointless.
+
+It would be different if optimization of a nonempty loop could produce
+an empty one. But this generally can't happen.
+
+@item
+Making side effects happen in the same order as in some other compiler.
+
+@cindex side effects, order of evaluation
+@cindex order of evaluation, side effects
+It is never safe to depend on the order of evaluation of side effects.
+For example, a function call like this may very well behave differently
+from one compiler to another:
+
+@example
+void func (int, int);
+
+int i = 2;
+func (i++, i++);
+@end example
+
+There is no guarantee (in either the C or the C++ standard language
+definitions) that the increments will be evaluated in any particular
+order. Either increment might happen first. @code{func} might get the
+arguments @samp{2, 3}, or it might get @samp{3, 2}, or even @samp{2, 2}.
+
+@item
+Not allowing structures with volatile fields in registers.
+
+Strictly speaking, there is no prohibition in the ANSI C standard
+against allowing structures with volatile fields in registers, but
+it does not seem to make any sense and is probably not what you wanted
+to do. So the compiler will give an error message in this case.
+@end itemize
+
+@node Warnings and Errors
+@section Warning Messages and Error Messages
+
+@cindex error messages
+@cindex warnings vs errors
+@cindex messages, warning and error
+The GNU compiler can produce two kinds of diagnostics: errors and
+warnings. Each kind has a different purpose:
+
+@itemize @w{}
+@item
+@emph{Errors} report problems that make it impossible to compile your
+program. GNU CC reports errors with the source file name and line
+number where the problem is apparent.
+
+@item
+@emph{Warnings} report other unusual conditions in your code that
+@emph{may} indicate a problem, although compilation can (and does)
+proceed. Warning messages also report the source file name and line
+number, but include the text @samp{warning:} to distinguish them
+from error messages.
+@end itemize
+
+Warnings may indicate danger points where you should check to make sure
+that your program really does what you intend; or the use of obsolete
+features; or the use of nonstandard features of GNU C or C++. Many
+warnings are issued only if you ask for them, with one of the @samp{-W}
+options (for instance, @samp{-Wall} requests a variety of useful
+warnings).
+
+GNU CC always tries to compile your program if possible; it never
+gratuitously rejects a program whose meaning is clear merely because
+(for instance) it fails to conform to a standard. In some cases,
+however, the C and C++ standards specify that certain extensions are
+forbidden, and a diagnostic @emph{must} be issued by a conforming
+compiler. The @samp{-pedantic} option tells GNU CC to issue warnings in
+such cases; @samp{-pedantic-errors} says to make them errors instead.
+This does not mean that @emph{all} non-ANSI constructs get warnings
+or errors.
+
+@xref{Warning Options,,Options to Request or Suppress Warnings}, for
+more detail on these and related command-line options.

+@cindex reporting bugs
+
+Your bug reports play an essential role in making GNU CC reliable.
+
+When you encounter a problem, the first thing to do is to see if it is
+already known. @xref{Trouble}. If it isn't known, then you should
+report the problem.
+
+Reporting a bug may help you by bringing a solution to your problem, or
+it may not. (If it does not, look in the service directory; see
+@ref{Service}.) In any case, the principal function of a bug report is
+to help the entire community by making the next version of GNU CC work
+better. Bug reports are your contribution to the maintenance of GNU CC.
+
+Since the maintainers are very overloaded, we cannot respond to every
+bug report. However, if the bug has not been fixed, we are likely to
+send you a patch and ask you to tell us whether it works.
+
+In order for a bug report to serve its purpose, you must include the
+information that makes for fixing the bug.

+@node Bug Criteria
+@section Have You Found a Bug?
+@cindex bug criteria
+
+If you are not sure whether you have found a bug, here are some guidelines:
+
+@itemize @bullet
+@cindex fatal signal
+@cindex core dump
+@item
+If the compiler gets a fatal signal, for any input whatever, that is a
+compiler bug. Reliable compilers never crash.
+
+@cindex invalid assembly code
+@cindex assembly code, invalid
+@item
+If the compiler produces invalid assembly code, for any input whatever
+(except an @code{asm} statement), that is a compiler bug, unless the
+compiler reports errors (not just warnings) which would ordinarily
+prevent the assembler from being run.
+
+@cindex undefined behavior
+@cindex undefined function value
+@cindex increment operators
+@item
+If the compiler produces valid assembly code that does not correctly
+execute the input source code, that is a compiler bug.
+
+However, you must double-check to make sure, because you may have run
+into an incompatibility between GNU C and traditional C
+(@pxref{Incompatibilities}). These incompatibilities might be considered
+bugs, but they are inescapable consequences of valuable features.
+
+Or you may have a program whose behavior is undefined, which happened
+by chance to give the desired results with another C or C++ compiler.
+
+For example, in many nonoptimizing compilers, you can write @samp{x;}
+at the end of a function instead of @samp{return x;}, with the same
+results. But the value of the function is undefined if @code{return}
+is omitted; it is not a bug when GNU CC produces different results.
+
+Problems often result from expressions with two increment operators,
+as in @code{f (*p++, *p++)}. Your previous compiler might have
+interpreted that expression the way you intended; GNU CC might
+interpret it another way. Neither compiler is wrong. The bug is
+in your code.
+
+After you have localized the error to a single source line, it should
+be easy to check for these things. If your program is correct and
+well defined, you have found a compiler bug.
+
+@item
+If the compiler produces an error message for valid input, that is a
+compiler bug.
+
+@cindex invalid input
+@item
+If the compiler does not produce an error message for invalid input,
+that is a compiler bug. However, you should note that your idea of
+``invalid input'' might be my idea of ``an extension'' or ``support
+for traditional practice''.
+
+@item
+If you are an experienced user of C or C++ compilers, your suggestions
+for improvement of GNU CC or GNU C++ are welcome in any case.

+@node Bug Reporting
+@section How to Report Bugs
+@cindex compiler bugs, reporting
+
+The fundamental principle of reporting bugs usefully is this:
+@strong{report all the facts}. If you are not sure whether to state a
+fact or leave it out, state it!
+
+Often people omit facts because they think they know what causes the
+problem and they conclude that some details don't matter. Thus, you might
+assume that the name of the variable you use in an example does not matter.
+Well, probably it doesn't, but one cannot be sure. Perhaps the bug is a
+stray memory reference which happens to fetch from the location where that
+name is stored in memory; perhaps, if the name were different, the contents
+of that location would fool the compiler into doing the right thing despite
+the bug. Play it safe and give a specific, complete example. That is the
+easiest thing for you to do, and the most helpful.
+
+Keep in mind that the purpose of a bug report is to enable someone to
+fix the bug if it is not known. It isn't very important what happens if
+the bug is already known. Therefore, always write your bug reports on
+the assumption that the bug is not known.
+
+Sometimes people give a few sketchy facts and ask, ``Does this ring a
+bell?'' This cannot help us fix a bug, so it is basically useless. We
+respond by asking for enough details to enable us to investigate.
+You might as well expedite matters by sending them to begin with.
+
+Try to make your bug report self-contained. If we have to ask you for
+more information, it is best if you include all the previous information
+in your response, as well as the information that was missing.
+
+Please report each bug in a separate message. This makes it easier for
+us to track which bugs have been fixed and to forward your bugs reports
+to the appropriate maintainer.
+
+Do not compress and encode any part of your bug report using programs
+such as @file{uuencode}. If you do so it will slow down the processing
+of your bug. If you must submit multiple large files, use @file{shar},
+which allows us to read your message without having to run any
+decompression programs.
+
+To enable someone to investigate the bug, you should include all these
+things:
+
+@itemize @bullet
+@item
+The version of GNU CC. You can get this by running it with the
+@samp{-v} option.
+
+Without this, we won't know whether there is any point in looking for
+the bug in the current version of GNU CC.
+
+@item
+A complete input file that will reproduce the bug. If the bug is in the
+C preprocessor, send a source file and any header files that it
+requires. If the bug is in the compiler proper (@file{cc1}), run your
+source file through the C preprocessor by doing @samp{gcc -E
+@var{sourcefile} > @var{outfile}}, then include the contents of
+@var{outfile} in the bug report. (When you do this, use the same
+@samp{-I}, @samp{-D} or @samp{-U} options that you used in actual
+compilation.)
+
+A single statement is not enough of an example. In order to compile it,
+it must be embedded in a complete file of compiler input; and the bug
+might depend on the details of how this is done.
+
+Without a real example one can compile, all anyone can do about your bug
+report is wish you luck. It would be futile to try to guess how to
+provoke the bug. For example, bugs in register allocation and reloading
+frequently depend on every little detail of the function they happen in.
+
+Even if the input file that fails comes from a GNU program, you should
+still send the complete test case. Don't ask the GNU CC maintainers to
+do the extra work of obtaining the program in question---they are all
+overworked as it is. Also, the problem may depend on what is in the
+header files on your system; it is unreliable for the GNU CC maintainers
+to try the problem with the header files available to them. By sending
+CPP output, you can eliminate this source of uncertainty and save us
+a certain percentage of wild goose chases.
+
+@item
+The command arguments you gave GNU CC or GNU C++ to compile that example
+and observe the bug. For example, did you use @samp{-O}? To guarantee
+you won't omit something important, list all the options.
+
+If we were to try to guess the arguments, we would probably guess wrong
+and then we would not encounter the bug.
+
+@item
+The type of machine you are using, and the operating system name and
+version number.
+
+@item
+The operands you gave to the @code{configure} command when you installed
+the compiler.
+
+@item
+A complete list of any modifications you have made to the compiler
+source. (We don't promise to investigate the bug unless it happens in
+an unmodified compiler. But if you've made modifications and don't tell
+us, then you are sending us on a wild goose chase.)
+
+Be precise about these changes. A description in English is not
+enough---send a context diff for them.
+
+Adding files of your own (such as a machine description for a machine we
+don't support) is a modification of the compiler source.
+
+@item
+Details of any other deviations from the standard procedure for installing
+GNU CC.
+
+@item
+A description of what behavior you observe that you believe is
+incorrect. For example, ``The compiler gets a fatal signal,'' or,
+``The assembler instruction at line 208 in the output is incorrect.''
+
+Of course, if the bug is that the compiler gets a fatal signal, then one
+can't miss it. But if the bug is incorrect output, the maintainer might
+not notice unless it is glaringly wrong. None of us has time to study
+all the assembler code from a 50-line C program just on the chance that
+one instruction might be wrong. We need @emph{you} to do this part!
+
+Even if the problem you experience is a fatal signal, you should still
+say so explicitly. Suppose something strange is going on, such as, your
+copy of the compiler is out of synch, or you have encountered a bug in
+the C library on your system. (This has happened!) Your copy might
+crash and the copy here would not. If you @i{said} to expect a crash,
+then when the compiler here fails to crash, we would know that the bug
+was not happening. If you don't say to expect a crash, then we would
+not know whether the bug was happening. We would not be able to draw
+any conclusion from our observations.
+
+If the problem is a diagnostic when compiling GNU CC with some other
+compiler, say whether it is a warning or an error.
+
+Often the observed symptom is incorrect output when your program is run.
+Sad to say, this is not enough information unless the program is short
+and simple. None of us has time to study a large program to figure out
+how it would work if compiled correctly, much less which line of it was
+compiled wrong. So you will have to do that. Tell us which source line
+it is, and what incorrect result happens when that line is executed. A
+person who understands the program can find this as easily as finding a
+bug in the program itself.
+
+@item
+If you send examples of assembler code output from GNU CC or GNU C++,
+please use @samp{-g} when you make them. The debugging information
+includes source line numbers which are essential for correlating the
+output with the input.
+
+@item
+If you wish to mention something in the GNU CC source, refer to it by
+context, not by line number.
+
+The line numbers in the development sources don't match those in your
+sources. Your line numbers would convey no useful information to the
+maintainers.
+
+@item
+Additional information from a debugger might enable someone to find a
+problem on a machine which he does not have available. However, you
+need to think when you collect this information if you want it to have
+any chance of being useful.
+
+@cindex backtrace for bug reports
+For example, many people send just a backtrace, but that is never
+useful by itself. A simple backtrace with arguments conveys little
+about GNU CC because the compiler is largely data-driven; the same
+functions are called over and over for different RTL insns, doing
+different things depending on the details of the insn.
+
+Most of the arguments listed in the backtrace are useless because they
+are pointers to RTL list structure. The numeric values of the
+pointers, which the debugger prints in the backtrace, have no
+significance whatever; all that matters is the contents of the objects
+they point to (and most of the contents are other such pointers).
+
+In addition, most compiler passes consist of one or more loops that
+scan the RTL insn sequence. The most vital piece of information about
+such a loop---which insn it has reached---is usually in a local variable,
+not in an argument.
+
+@findex debug_rtx
+What you need to provide in addition to a backtrace are the values of
+the local variables for several stack frames up. When a local
+variable or an argument is an RTX, first print its value and then use
+the GDB command @code{pr} to print the RTL expression that it points
+to. (If GDB doesn't run on your machine, use your debugger to call
+the function @code{debug_rtx} with the RTX as an argument.) In
+general, whenever a variable is a pointer, its value is no use
+without the data it points to.
+@end itemize
+
+Here are some things that are not necessary:
+
+@itemize @bullet
+@item
+A description of the envelope of the bug.
+
+Often people who encounter a bug spend a lot of time investigating
+which changes to the input file will make the bug go away and which
+changes will not affect it.
+
+This is often time consuming and not very useful, because the way we
+will find the bug is by running a single example under the debugger with
+breakpoints, not by pure deduction from a series of examples. You might
+as well save your time for something else.
+
+Of course, if you can find a simpler example to report @emph{instead} of
+the original one, that is a convenience. Errors in the output will be
+easier to spot, running under the debugger will take less time, etc.
+Most GNU CC bugs involve just one function, so the most straightforward
+way to simplify an example is to delete all the function definitions
+except the one where the bug occurs. Those earlier in the file may be
+replaced by external declarations if the crucial function depends on
+them. (Exception: inline functions may affect compilation of functions
+defined later in the file.)
+
+However, simplification is not vital; if you don't want to do this,
+report the bug anyway and send the entire test case you used.
+
+@item
+In particular, some people insert conditionals @samp{#ifdef BUG} around
+a statement which, if removed, makes the bug not happen. These are just
+clutter; we won't pay any attention to them anyway. Besides, you should
+send us cpp output, and that can't have conditionals.
+
+@item
+A patch for the bug.
+
+A patch for the bug is useful if it is a good one. But don't omit the
+necessary information, such as the test case, on the assumption that a
+patch is all we need. We might see problems with your patch and decide
+to fix the problem another way, or we might not understand it at all.
+
+Sometimes with a program as complicated as GNU CC it is very hard to
+construct an example that will make the program follow a certain path
+through the code. If you don't send the example, we won't be able to
+construct one, so we won't be able to verify that the bug is fixed.
+
+And if we can't understand what bug you are trying to fix, or why your
+patch should be an improvement, we won't install it. A test case will
+help us to understand.
+
+@xref{Sending Patches}, for guidelines on how to make it easy for us to
+understand and install your patches.
+
+@item
+A guess about what the bug is or what it depends on.
+
+Such guesses are usually wrong. Even I can't guess right about such
+things without first using the debugger to find the facts.
+
+@item
+A core dump file.
+
+We have no way of examining a core dump for your type of machine
+unless we have an identical system---and if we do have one,
+we should be able to reproduce the crash ourselves.

+Send an explanation with your changes of what problem they fix or what

+
+(Referring to a bug report is not as good as including it, because then
+we will have to look it up, and we have probably already deleted it if
+we've already fixed the bug.)
+
+@item
+Always include a proper bug report for the problem you think you have

+Include all the comments that are appropriate to help people reading the

+
+@item
+Don't mix together changes made for different reasons.
+Send them @emph{individually}.
+
+If you make two changes for separate reasons, then we might not want to
+install them both. We might want to install just one. If you send them
+all jumbled together in a single set of diffs, we have to do extra work
+to disentangle them---to figure out which parts of the change serve
+which purpose. If we don't have time for this, we might have to ignore
+your changes entirely.
+
+If you send each change as soon as you have written it, with its own
+explanation, then the two changes never get tangled up, and we can
+consider each one properly without any extra work to disentangle them.
+
+Ideally, each change you send should be impossible to subdivide into
+parts that we might want to consider separately, because each of its
+parts gets its motivation from the other parts.
+
+@item
+Send each change as soon as that change is finished. Sometimes people
+think they are helping us by accumulating many changes to send them all
+together. As explained above, this is absolutely the worst thing you
+could do.
+
+Since you should send each change separately, you might as well send it
+right away. That gives us the option of installing it immediately if it
+is important.
+
+@item

+that. At best it might tell us how to write another patch that would
+solve the problem acceptably.
+
+Sometimes people send fixes that @emph{might} be an improvement in
+general---but it is hard to be sure of this. It's hard to install
+such changes because we have to study them very carefully. Of course,
+a good explanation of the reasoning by which you concluded the change
+was correct can help convince us.
+
+The safest changes are changes to the configuration files for a

+on other machines.

+@section Include Files and VMS
+
+@cindex include files and VMS
+@cindex VMS and include files
+@cindex header files and VMS
+Due to the differences between the filesystems of Unix and VMS, GNU CC
+attempts to translate file names in @samp{#include} into names that VMS
+will understand. The basic strategy is to prepend a prefix to the
+specification of the include file, convert the whole filename to a VMS
+filename, and then try to open the file. GNU CC tries various prefixes
+one by one until one of them succeeds:
+
+@enumerate
+@item
+The first prefix is the @samp{GNU_CC_INCLUDE:} logical name: this is
+where GNU C header files are traditionally stored. If you wish to store
+header files in non-standard locations, then you can assign the logical
+@samp{GNU_CC_INCLUDE} to be a search list, where each element of the
+list is suitable for use with a rooted logical.
+
+@item
+The next prefix tried is @samp{SYS$SYSROOT:[SYSLIB.]}. This is where
+VAX-C header files are traditionally stored.
+
+@item
+If the include file specification by itself is a valid VMS filename, the
+preprocessor then uses this name with no prefix in an attempt to open
+the include file.
+
+@item
+If the file specification is not a valid VMS filename (i.e. does not
+contain a device or a directory specifier, and contains a @samp{/}
+character), the preprocessor tries to convert it from Unix syntax to
+VMS syntax.
+
+Conversion works like this: the first directory name becomes a device,
+and the rest of the directories are converted into VMS-format directory
+names. For example, the name @file{X11/foobar.h} is
+translated to @file{X11:[000000]foobar.h} or @file{X11:foobar.h},
+whichever one can be opened. This strategy allows you to assign a
+logical name to point to the actual location of the header files.
+
+@item
+If none of these strategies succeeds, the @samp{#include} fails.
+@end enumerate
+
+Include directives of the form:
+
+@example
+#include foobar
+@end example
+
+@noindent
+are a common source of incompatibility between VAX-C and GNU CC. VAX-C
+treats this much like a standard @code{#include <foobar.h>} directive.
+That is incompatible with the ANSI C behavior implemented by GNU CC: to
+expand the name @code{foobar} as a macro. Macro expansion should
+eventually yield one of the two standard formats for @code{#include}:
+
+@example
+#include "@var{file}"
+#include <@var{file}>
+@end example
+
+If you have this problem, the best solution is to modify the source to
+convert the @code{#include} directives to one of the two standard forms.
+That will work with either compiler. If you want a quick and dirty fix,
+define the file names as macros with the proper expansion, like this:
+
+@example
+#define stdio <stdio.h>
+@end example
+
+@noindent
+This will work, as long as the name doesn't conflict with anything else
+in the program.
+
+Another source of incompatibility is that VAX-C assumes that:
+
+@example
+#include "foobar"
+@end example
+
+@noindent
+is actually asking for the file @file{foobar.h}. GNU CC does not
+make this assumption, and instead takes what you ask for literally;
+it tries to read the file @file{foobar}. The best way to avoid this
+problem is to always specify the desired file extension in your include
+directives.
+
+GNU CC for VMS is distributed with a set of include files that is
+sufficient to compile most general purpose programs. Even though the
+GNU CC distribution does not contain header files to define constants
+and structures for some VMS system-specific functions, there is no
+reason why you cannot use GNU CC with any of these functions. You first
+may have to generate or create header files, either by using the public
+domain utility @code{UNSDL} (which can be found on a DECUS tape), or by
+extracting the relevant modules from one of the system macro libraries,
+and using an editor to construct a C header file.
+
+A @code{#include} file name cannot contain a DECNET node name. The
+preprocessor reports an I/O error if you attempt to use a node name,
+whether explicitly, or implicitly via a logical name.
+
+@node Global Declarations
+@section Global Declarations and VMS
+
+@findex GLOBALREF
+@findex GLOBALDEF
+@findex GLOBALVALUEDEF
+@findex GLOBALVALUEREF
+GNU CC does not provide the @code{globalref}, @code{globaldef} and
+@code{globalvalue} keywords of VAX-C. You can get the same effect with
+an obscure feature of GAS, the GNU assembler. (This requires GAS
+version 1.39 or later.) The following macros allow you to use this
+feature in a fairly natural way:
+
+@smallexample
+#ifdef __GNUC__
+#define GLOBALREF(TYPE,NAME) \
+ TYPE NAME \
+ asm ("_$$PsectAttributes_GLOBALSYMBOL$$" #NAME)
+#define GLOBALDEF(TYPE,NAME,VALUE) \
+ TYPE NAME \
+ asm ("_$$PsectAttributes_GLOBALSYMBOL$$" #NAME) \
+ = VALUE
+#define GLOBALVALUEREF(TYPE,NAME) \
+ const TYPE NAME[1] \
+ asm ("_$$PsectAttributes_GLOBALVALUE$$" #NAME)
+#define GLOBALVALUEDEF(TYPE,NAME,VALUE) \
+ const TYPE NAME[1] \
+ asm ("_$$PsectAttributes_GLOBALVALUE$$" #NAME) \
+ = @{VALUE@}
+#else
+#define GLOBALREF(TYPE,NAME) \
+ globalref TYPE NAME
+#define GLOBALDEF(TYPE,NAME,VALUE) \
+ globaldef TYPE NAME = VALUE
+#define GLOBALVALUEDEF(TYPE,NAME,VALUE) \
+ globalvalue TYPE NAME = VALUE
+#define GLOBALVALUEREF(TYPE,NAME) \
+ globalvalue TYPE NAME
+#endif
+@end smallexample
+
+@noindent
+(The @code{_$$PsectAttributes_GLOBALSYMBOL} prefix at the start of the
+name is removed by the assembler, after it has modified the attributes
+of the symbol). These macros are provided in the VMS binaries
+distribution in a header file @file{GNU_HACKS.H}. An example of the
+usage is:
+
+@example
+GLOBALREF (int, ijk);
+GLOBALDEF (int, jkl, 0);
+@end example
+
+The macros @code{GLOBALREF} and @code{GLOBALDEF} cannot be used
+straightforwardly for arrays, since there is no way to insert the array
+dimension into the declaration at the right place. However, you can
+declare an array with these macros if you first define a typedef for the
+array type, like this:
+
+@example
+typedef int intvector[10];
+GLOBALREF (intvector, foo);
+@end example
+
+Array and structure initializers will also break the macros; you can
+define the initializer to be a macro of its own, or you can expand the
+@code{GLOBALDEF} macro by hand. You may find a case where you wish to
+use the @code{GLOBALDEF} macro with a large array, but you are not
+interested in explicitly initializing each element of the array. In
+such cases you can use an initializer like: @code{@{0,@}}, which will
+initialize the entire array to @code{0}.
+
+A shortcoming of this implementation is that a variable declared with
+@code{GLOBALVALUEREF} or @code{GLOBALVALUEDEF} is always an array. For
+example, the declaration:
+
+@example
+GLOBALVALUEREF(int, ijk);
+@end example
+
+@noindent
+declares the variable @code{ijk} as an array of type @code{int [1]}.
+This is done because a globalvalue is actually a constant; its ``value''
+is what the linker would normally consider an address. That is not how
+an integer value works in C, but it is how an array works. So treating
+the symbol as an array name gives consistent results---with the
+exception that the value seems to have the wrong type. @strong{Don't
+try to access an element of the array.} It doesn't have any elements.
+The array ``address'' may not be the address of actual storage.
+
+The fact that the symbol is an array may lead to warnings where the
+variable is used. Insert type casts to avoid the warnings. Here is an
+example; it takes advantage of the ANSI C feature allowing macros that
+expand to use the same name as the macro itself.
+
+@example
+GLOBALVALUEREF (int, ss$_normal);
+GLOBALVALUEDEF (int, xyzzy,123);
+#ifdef __GNUC__
+#define ss$_normal ((int) ss$_normal)
+#define xyzzy ((int) xyzzy)
+#endif
+@end example
+
+Don't use @code{globaldef} or @code{globalref} with a variable whose
+type is an enumeration type; this is not implemented. Instead, make the
+variable an integer, and use a @code{globalvaluedef} for each of the
+enumeration values. An example of this would be:
+
+@example
+#ifdef __GNUC__
+GLOBALDEF (int, color, 0);
+GLOBALVALUEDEF (int, RED, 0);
+GLOBALVALUEDEF (int, BLUE, 1);
+GLOBALVALUEDEF (int, GREEN, 3);
+#else
+enum globaldef color @{RED, BLUE, GREEN = 3@};
+#endif
+@end example
+
+@node VMS Misc
+@section Other VMS Issues
+
+@cindex exit status and VMS
+@cindex return value of @code{main}
+@cindex @code{main} and the exit status
+GNU CC automatically arranges for @code{main} to return 1 by default if
+you fail to specify an explicit return value. This will be interpreted
+by VMS as a status code indicating a normal successful completion.
+Version 1 of GNU CC did not provide this default.
+
+GNU CC on VMS works only with the GNU assembler, GAS. You need version
+1.37 or later of GAS in order to produce value debugging information for
+the VMS debugger. Use the ordinary VMS linker with the object files
+produced by GAS.
+
+@cindex shared VMS run time system
+@cindex @file{VAXCRTL}
+Under previous versions of GNU CC, the generated code would occasionally
+give strange results when linked to the sharable @file{VAXCRTL} library.
+Now this should work.
+
+A caveat for use of @code{const} global variables: the @code{const}
+modifier must be specified in every external declaration of the variable
+in all of the source files that use that variable. Otherwise the linker
+will issue warnings about conflicting attributes for the variable. Your
+program will still work despite the warnings, but the variable will be
+placed in writable storage.
+
+@cindex name augmentation
+@cindex case sensitivity and VMS
+@cindex VMS and case sensitivity
+Although the VMS linker does distinguish between upper and lower case
+letters in global symbols, most VMS compilers convert all such symbols
+into upper case and most run-time library routines also have upper case
+names. To be able to reliably call such routines, GNU CC (by means of
+the assembler GAS) converts global symbols into upper case like other
+VMS compilers. However, since the usual practice in C is to distinguish
+case, GNU CC (via GAS) tries to preserve usual C behavior by augmenting
+each name that is not all lower case. This means truncating the name
+to at most 23 characters and then adding more characters at the end
+which encode the case pattern of those 23. Names which contain at
+least one dollar sign are an exception; they are converted directly into
+upper case without augmentation.
+
+Name augmentation yields bad results for programs that use precompiled
+libraries (such as Xlib) which were generated by another compiler. You
+can use the compiler option @samp{/NOCASE_HACK} to inhibit augmentation;
+it makes external C functions and variables case-independent as is usual
+on VMS. Alternatively, you could write all references to the functions
+and variables in such libraries using lower case; this will work on VMS,
+but is not portable to other systems. The compiler option @samp{/NAMES}
+also provides control over global name handling.
+
+Function and variable names are handled somewhat differently with GNU
+C++. The GNU C++ compiler performs @dfn{name mangling} on function
+names, which means that it adds information to the function name to
+describe the data types of the arguments that the function takes. One
+result of this is that the name of a function can become very long.
+Since the VMS linker only recognizes the first 31 characters in a name,
+special action is taken to ensure that each function and variable has a
+unique name that can be represented in 31 characters.
+
+If the name (plus a name augmentation, if required) is less than 32
+characters in length, then no special action is performed. If the name
+is longer than 31 characters, the assembler (GAS) will generate a
+hash string based upon the function name, truncate the function name to
+23 characters, and append the hash string to the truncated name. If the
+@samp{/VERBOSE} compiler option is used, the assembler will print both
+the full and truncated names of each symbol that is truncated.
+
+The @samp{/NOCASE_HACK} compiler option should not be used when you are
+compiling programs that use libg++. libg++ has several instances of
+objects (i.e. @code{Filebuf} and @code{filebuf}) which become
+indistinguishable in a case-insensitive environment. This leads to
+cases where you need to inhibit augmentation selectively (if you were
+using libg++ and Xlib in the same program, for example). There is no
+special feature for doing this, but you can get the result by defining a
+macro for each mixed case symbol for which you wish to inhibit
+augmentation. The macro should expand into the lower case equivalent of
+itself. For example:
+
+@example
+#define StuDlyCapS studlycaps
+@end example
+
+These macro definitions can be placed in a header file to minimize the
+number of changes to your source code.

+@chapter GNU CC and Portability
+@cindex portability
+@cindex GNU CC and portability
+
+The main goal of GNU CC was to make a good, fast compiler for machines in
+the class that the GNU system aims to run on: 32-bit machines that address
+8-bit bytes and have several general registers. Elegance, theoretical
+power and simplicity are only secondary.
+
+GNU CC gets most of the information about the target machine from a machine
+description which gives an algebraic formula for each of the machine's
+instructions. This is a very clean way to describe the target. But when
+the compiler needs information that is difficult to express in this
+fashion, I have not hesitated to define an ad-hoc parameter to the machine
+description. The purpose of portability is to reduce the total work needed
+on the compiler; it was not of interest for its own sake.
+
+@cindex endianness
+@cindex autoincrement addressing, availability
+@findex abort
+GNU CC does not contain machine dependent code, but it does contain code
+that depends on machine parameters such as endianness (whether the most
+significant byte has the highest or lowest address of the bytes in a word)
+and the availability of autoincrement addressing. In the RTL-generation
+pass, it is often necessary to have multiple strategies for generating code
+for a particular kind of syntax tree, strategies that are usable for different
+combinations of parameters. Often I have not tried to address all possible
+cases, but only the common ones or only the ones that I have encountered.
+As a result, a new target may require additional strategies. You will know
+if this happens because the compiler will call @code{abort}. Fortunately,
+the new strategies can be added in a machine-independent fashion, and will
+affect only the target machines that need them.

+@chapter Interfacing to GNU CC Output
+@cindex interfacing to GNU CC output
+@cindex run-time conventions
+@cindex function call conventions
+@cindex conventions, run-time
+
+GNU CC is normally configured to use the same function calling convention
+normally in use on the target system. This is done with the
+machine-description macros described (@pxref{Target Macros}).
+
+@cindex unions, returning
+@cindex structures, returning
+@cindex returning structures and unions
+However, returning of structure and union values is done differently on
+some target machines. As a result, functions compiled with PCC
+returning such types cannot be called from code compiled with GNU CC,
+and vice versa. This does not cause trouble often because few Unix
+library routines return structures or unions.
+
+GNU CC code returns structures and unions that are 1, 2, 4 or 8 bytes
+long in the same registers used for @code{int} or @code{double} return
+values. (GNU CC typically allocates variables of such types in
+registers also.) Structures and unions of other sizes are returned by
+storing them into an address passed by the caller (usually in a
+register). The machine-description macros @code{STRUCT_VALUE} and
+@code{STRUCT_INCOMING_VALUE} tell GNU CC where to pass this address.
+
+By contrast, PCC on most target machines returns structures and unions
+of any size by copying the data into an area of static storage, and then
+returning the address of that storage as if it were a pointer value.
+The caller must copy the data from that memory area to the place where
+the value is wanted. This is slower than the method used by GNU CC, and
+fails to be reentrant.
+
+On some target machines, such as RISC machines and the 80386, the
+standard system convention is to pass to the subroutine the address of
+where to return the value. On these machines, GNU CC has been
+configured to be compatible with the standard compiler, when this method
+is used. It may not be compatible for structures of 1, 2, 4 or 8 bytes.
+
+@cindex argument passing
+@cindex passing arguments
+GNU CC uses the system's standard convention for passing arguments. On
+some machines, the first few arguments are passed in registers; in
+others, all are passed on the stack. It would be possible to use
+registers for argument passing on any machine, and this would probably
+result in a significant speedup. But the result would be complete
+incompatibility with code that follows the standard convention. So this
+change is practical only if you are switching to GNU CC as the sole C
+compiler for the system. We may implement register argument passing on
+certain machines once we have a complete GNU system so that we can
+compile the libraries with GNU CC.
+
+On some machines (particularly the Sparc), certain types of arguments
+are passed ``by invisible reference''. This means that the value is
+stored in memory, and the address of the memory location is passed to
+the subroutine.
+
+@cindex @code{longjmp} and automatic variables
+If you use @code{longjmp}, beware of automatic variables. ANSI C says that
+automatic variables that are not declared @code{volatile} have undefined
+values after a @code{longjmp}. And this is all GNU CC promises to do,
+because it is very difficult to restore register variables correctly, and
+one of GNU CC's features is that it can put variables in registers without
+your asking it to.
+
+If you want a variable to be unaltered by @code{longjmp}, and you don't
+want to write @code{volatile} because old C compilers don't accept it,
+just take the address of the variable. If a variable's address is ever
+taken, even if just to compute it and ignore it, then the variable cannot
+go in a register:
+
+@example
+@{
+ int careful;
+ &careful;
+ @dots{}
+@}
+@end example
+
+@cindex arithmetic libraries
+@cindex math libraries
+Code compiled with GNU CC may call certain library routines. Most of
+them handle arithmetic for which there are no instructions. This
+includes multiply and divide on some machines, and floating point
+operations on any machine for which floating point support is disabled
+with @samp{-msoft-float}. Some standard parts of the C library, such as
+@code{bcopy} or @code{memcpy}, are also called automatically. The usual
+function call interface is used for calling the library routines.
+
+These library routines should be defined in the library @file{libgcc.a},
+which GNU CC automatically searches whenever it links a program. On
+machines that have multiply and divide instructions, if hardware
+floating point is in use, normally @file{libgcc.a} is not needed, but it
+is searched just in case.
+
+Each arithmetic function is defined in @file{libgcc1.c} to use the
+corresponding C arithmetic operator. As long as the file is compiled
+with another C compiler, which supports all the C arithmetic operators,
+this file will work portably. However, @file{libgcc1.c} does not work if
+compiled with GNU CC, because each arithmetic function would compile
+into a call to itself!

+
+@cindex parsing pass
+The parsing pass is invoked only once, to parse the entire input. The RTL
+intermediate code for a function is generated as the function is parsed, a
+statement at a time. Each statement is read in as a syntax tree and then
+converted to RTL; then the storage for the tree for the statement is
+reclaimed. Storage for types (and the expressions for their sizes),
+declarations, and a representation of the binding contours and how they nest,
+remain until the function is finished being compiled; these are all needed
+to output the debugging information.
+
+@findex rest_of_compilation

+responsible for all further processing necessary, ending with output of
+the assembler language. All other compiler passes run, in sequence,

+@file{objc-parse.y}, @file{objc-actions.c}, @file{objc-tree.def}, and
+@file{objc-actions.h}. Certain C-specific files are used for this as
+well.
+
+The file @file{c-common.c} is also used for all of the above languages.
+
+@cindex RTL generation
+@item
+RTL generation. This is the conversion of syntax tree into RTL code.
+It is actually done statement-by-statement during parsing, but for
+most purposes it can be thought of as a separate pass.
+
+@cindex target-parameter-dependent code
+This is where the bulk of target-parameter-dependent code is found,
+since often it is necessary for strategies to apply only when certain
+standard kinds of instructions are available. The purpose of named
+instruction patterns is to provide this information to the RTL
+generation pass.
+
+@cindex tail recursion optimization
+Optimization is done in this pass for @code{if}-conditions that are
+comparisons, boolean operations or conditional expressions. Tail
+recursion is detected at this time also. Decisions are made about how
+best to arrange loops and how to output @code{switch} statements.
+
+@c Avoiding overfull is tricky here.
+The source files for RTL generation include
+@file{stmt.c},
+@file{calls.c},
+@file{expr.c},
+@file{explow.c},
+@file{expmed.c},
+@file{function.c},
+@file{optabs.c}
+and @file{emit-rtl.c}.
+Also, the file
+@file{insn-emit.c}, generated from the machine description by the
+program @code{genemit}, is used in this pass. The header file
+@file{expr.h} is used for communication within this pass.@refill
+
+@findex genflags
+@findex gencodes
+The header files @file{insn-flags.h} and @file{insn-codes.h},
+generated from the machine description by the programs @code{genflags}
+and @code{gencodes}, tell this pass which standard names are available
+for use and which patterns correspond to them.@refill
+
+Aside from debugging information output, none of the following passes
+refers to the tree structure representation of the function (only
+part of which is saved).
+
+@cindex inline, automatic
+The decision of whether the function can and should be expanded inline
+in its subsequent callers is made at the end of rtl generation. The
+function must meet certain criteria, currently related to the size of
+the function and the types and number of parameters it has. Note that
+this function may contain loops, recursive calls to itself
+(tail-recursive functions can be inlined!), gotos, in short, all
+constructs supported by GNU CC. The file @file{integrate.c} contains
+the code to save a function's rtl for later inlining and to inline that
+rtl when the function is called. The header file @file{integrate.h}
+is also used for this purpose.
+
+The option @samp{-dr} causes a debugging dump of the RTL code after
+this pass. This dump file's name is made by appending @samp{.rtl} to
+the input file name.
+
+@cindex jump optimization
+@cindex unreachable code
+@cindex dead code
+@item
+Jump optimization. This pass simplifies jumps to the following
+instruction, jumps across jumps, and jumps to jumps. It deletes
+unreferenced labels and unreachable code, except that unreachable code
+that contains a loop is not recognized as unreachable in this pass.
+(Such loops are deleted later in the basic block analysis.) It also
+converts some code originally written with jumps into sequences of
+instructions that directly set values from the results of comparisons,
+if the machine has such instructions.
+
+Jump optimization is performed two or three times. The first time is
+immediately following RTL generation. The second time is after CSE,
+but only if CSE says repeated jump optimization is needed. The
+last time is right before the final pass. That time, cross-jumping
+and deletion of no-op move instructions are done together with the
+optimizations described above.
+
+The source file of this pass is @file{jump.c}.
+
+The option @samp{-dj} causes a debugging dump of the RTL code after
+this pass is run for the first time. This dump file's name is made by
+appending @samp{.jump} to the input file name.
+
+@cindex register use analysis
+@item
+Register scan. This pass finds the first and last use of each
+register, as a guide for common subexpression elimination. Its source
+is in @file{regclass.c}.
+
+@cindex jump threading
+@item
+Jump threading. This pass detects a condition jump that branches to an
+identical or inverse test. Such jumps can be @samp{threaded} through
+the second conditional test. The source code for this pass is in
+@file{jump.c}. This optimization is only performed if
+@samp{-fthread-jumps} is enabled.
+
+@cindex common subexpression elimination
+@cindex constant propagation
+@item
+Common subexpression elimination. This pass also does constant
+propagation. Its source file is @file{cse.c}. If constant
+propagation causes conditional jumps to become unconditional or to
+become no-ops, jump optimization is run again when CSE is finished.
+
+The option @samp{-ds} causes a debugging dump of the RTL code after
+this pass. This dump file's name is made by appending @samp{.cse} to
+the input file name.
+
+@cindex loop optimization
+@cindex code motion
+@cindex strength-reduction
+@item
+Loop optimization. This pass moves constant expressions out of loops,
+and optionally does strength-reduction and loop unrolling as well.
+Its source files are @file{loop.c} and @file{unroll.c}, plus the header
+@file{loop.h} used for communication between them. Loop unrolling uses
+some functions in @file{integrate.c} and the header @file{integrate.h}.
+
+The option @samp{-dL} causes a debugging dump of the RTL code after
+this pass. This dump file's name is made by appending @samp{.loop} to
+the input file name.
+
+@item
+If @samp{-frerun-cse-after-loop} was enabled, a second common
+subexpression elimination pass is performed after the loop optimization
+pass. Jump threading is also done again at this time if it was specified.
+
+The option @samp{-dt} causes a debugging dump of the RTL code after
+this pass. This dump file's name is made by appending @samp{.cse2} to
+the input file name.
+
+@cindex register allocation, stupid
+@cindex stupid register allocation
+@item
+Stupid register allocation is performed at this point in a
+nonoptimizing compilation. It does a little data flow analysis as
+well. When stupid register allocation is in use, the next pass
+executed is the reloading pass; the others in between are skipped.
+The source file is @file{stupid.c}.
+
+@cindex data flow analysis
+@cindex analysis, data flow
+@cindex basic blocks
+@item
+Data flow analysis (@file{flow.c}). This pass divides the program
+into basic blocks (and in the process deletes unreachable loops); then
+it computes which pseudo-registers are live at each point in the
+program, and makes the first instruction that uses a value point at
+the instruction that computed the value.
+
+@cindex autoincrement/decrement analysis
+This pass also deletes computations whose results are never used, and
+combines memory references with add or subtract instructions to make
+autoincrement or autodecrement addressing.
+
+The option @samp{-df} causes a debugging dump of the RTL code after
+this pass. This dump file's name is made by appending @samp{.flow} to
+the input file name. If stupid register allocation is in use, this
+dump file reflects the full results of such allocation.
+
+@cindex instruction combination
+@item
+Instruction combination (@file{combine.c}). This pass attempts to
+combine groups of two or three instructions that are related by data
+flow into single instructions. It combines the RTL expressions for
+the instructions by substitution, simplifies the result using algebra,
+and then attempts to match the result against the machine description.
+
+The option @samp{-dc} causes a debugging dump of the RTL code after
+this pass. This dump file's name is made by appending @samp{.combine}
+to the input file name.
+
+@cindex instruction scheduling
+@cindex scheduling, instruction
+@item
+Instruction scheduling (@file{sched.c}). This pass looks for
+instructions whose output will not be available by the time that it is
+used in subsequent instructions. (Memory loads and floating point
+instructions often have this behavior on RISC machines). It re-orders
+instructions within a basic block to try to separate the definition and
+use of items that otherwise would cause pipeline stalls.
+
+Instruction scheduling is performed twice. The first time is immediately
+after instruction combination and the second is immediately after reload.
+
+The option @samp{-dS} causes a debugging dump of the RTL code after this
+pass is run for the first time. The dump file's name is made by
+appending @samp{.sched} to the input file name.
+
+@cindex register class preference pass
+@item
+Register class preferencing. The RTL code is scanned to find out
+which register class is best for each pseudo register. The source
+file is @file{regclass.c}.
+
+@cindex register allocation
+@cindex local register allocation
+@item
+Local register allocation (@file{local-alloc.c}). This pass allocates
+hard registers to pseudo registers that are used only within one basic
+block. Because the basic block is linear, it can use fast and
+powerful techniques to do a very good job.
+
+The option @samp{-dl} causes a debugging dump of the RTL code after
+this pass. This dump file's name is made by appending @samp{.lreg} to
+the input file name.
+
+@cindex global register allocation
+@item
+Global register allocation (@file{global.c}). This pass
+allocates hard registers for the remaining pseudo registers (those
+whose life spans are not contained in one basic block).
+
+@cindex reloading
+@item
+Reloading. This pass renumbers pseudo registers with the hardware
+registers numbers they were allocated. Pseudo registers that did not
+get hard registers are replaced with stack slots. Then it finds
+instructions that are invalid because a value has failed to end up in
+a register, or has ended up in a register of the wrong kind. It fixes
+up these instructions by reloading the problematical values
+temporarily into registers. Additional instructions are generated to
+do the copying.
+
+The reload pass also optionally eliminates the frame pointer and inserts
+instructions to save and restore call-clobbered registers around calls.
+
+Source files are @file{reload.c} and @file{reload1.c}, plus the header
+@file{reload.h} used for communication between them.
+
+The option @samp{-dg} causes a debugging dump of the RTL code after
+this pass. This dump file's name is made by appending @samp{.greg} to
+the input file name.
+
+@cindex instruction scheduling
+@cindex scheduling, instruction
+@item
+Instruction scheduling is repeated here to try to avoid pipeline stalls
+due to memory loads generated for spilled pseudo registers.
+
+The option @samp{-dR} causes a debugging dump of the RTL code after
+this pass. This dump file's name is made by appending @samp{.sched2}
+to the input file name.
+
+@cindex cross-jumping
+@cindex no-op move instructions
+@item
+Jump optimization is repeated, this time including cross-jumping
+and deletion of no-op move instructions.
+
+The option @samp{-dJ} causes a debugging dump of the RTL code after
+this pass. This dump file's name is made by appending @samp{.jump2}
+to the input file name.
+
+@cindex delayed branch scheduling
+@cindex scheduling, delayed branch
+@item
+Delayed branch scheduling. This optional pass attempts to find
+instructions that can go into the delay slots of other instructions,
+usually jumps and calls. The source file name is @file{reorg.c}.
+
+The option @samp{-dd} causes a debugging dump of the RTL code after
+this pass. This dump file's name is made by appending @samp{.dbr}
+to the input file name.
+
+@cindex register-to-stack conversion
+@item
+Conversion from usage of some hard registers to usage of a register
+stack may be done at this point. Currently, this is supported only
+for the floating-point registers of the Intel 80387 coprocessor. The
+source file name is @file{reg-stack.c}.
+
+The options @samp{-dk} causes a debugging dump of the RTL code after
+this pass. This dump file's name is made by appending @samp{.stack}
+to the input file name.
+
+@cindex final pass
+@cindex peephole optimization
+@item
+Final. This pass outputs the assembler code for the function. It is
+also responsible for identifying spurious test and compare
+instructions. Machine-specific peephole optimizations are performed
+at the same time. The function entry and exit sequences are generated
+directly as assembler code in this pass; they never exist as RTL.
+
+The source files are @file{final.c} plus @file{insn-output.c}; the
+latter is generated automatically from the machine description by the
+tool @file{genoutput}. The header file @file{conditions.h} is used
+for communication between these files.
+
+@cindex debugging information generation
+@item
+Debugging information output. This is run after final because it must
+output the stack slot offsets for pseudo registers that did not get
+hard registers. Source files are @file{dbxout.c} for DBX symbol table
+format, @file{sdbout.c} for SDB symbol table format, and
+@file{dwarfout.c} for DWARF symbol table format.
+@end itemize
+
+Some additional files are used by all or many passes:
+
+@itemize @bullet
+@item
+Every pass uses @file{machmode.def} and @file{machmode.h} which define
+the machine modes.
+
+@item
+Several passes use @file{real.h}, which defines the default
+representation of floating point constants and how to operate on them.
+
+@item
+All the passes that work with RTL use the header files @file{rtl.h}
+and @file{rtl.def}, and subroutines in file @file{rtl.c}. The tools
+@code{gen*} also use these files to read and work with the machine
+description RTL.
+
+@findex genconfig
+@item
+Several passes refer to the header file @file{insn-config.h} which
+contains a few parameters (C macro definitions) generated
+automatically from the machine description RTL by the tool
+@code{genconfig}.
+
+@cindex instruction recognizer
+@item
+Several passes use the instruction recognizer, which consists of
+@file{recog.c} and @file{recog.h}, plus the files @file{insn-recog.c}
+and @file{insn-extract.c} that are generated automatically from the
+machine description by the tools @file{genrecog} and
+@file{genextract}.@refill
+
+@item
+Several passes use the header files @file{regs.h} which defines the
+information recorded about pseudo register usage, and @file{basic-block.h}
+which defines the information recorded about basic blocks.
+
+@item
+@file{hard-reg-set.h} defines the type @code{HARD_REG_SET}, a bit-vector
+with a bit for each hard register, and some macros to manipulate it.
+This type is just @code{int} if the machine has few enough hard registers;
+otherwise it is an array of @code{int} and some of the macros expand
+into loops.
+
+@item
+Several passes use instruction attributes. A definition of the
+attributes defined for a particular machine is in file
+@file{insn-attr.h}, which is generated from the machine description by
+the program @file{genattr}. The file @file{insn-attrtab.c} contains
+subroutines to obtain the attribute values for insns. It is generated

+@chapter The Configuration File
+@cindex configuration file
+@cindex @file{xm-@var{machine}.h}
+
+The configuration file @file{xm-@var{machine}.h} contains macro
+definitions that describe the machine and system on which the compiler
+is running, unlike the definitions in @file{@var{machine}.h}, which
+describe the machine for which the compiler is producing output. Most
+of the values in @file{xm-@var{machine}.h} are actually the same on all
+machines that GNU CC runs on, so large parts of all configuration files
+are identical. But there are some macros that vary:
+
+@table @code
+@findex USG
+@item USG
+Define this macro if the host system is System V.
+
+@findex VMS
+@item VMS
+Define this macro if the host system is VMS.
+
+@findex FATAL_EXIT_CODE
+@item FATAL_EXIT_CODE
+A C expression for the status code to be returned when the compiler
+exits after serious errors.
+
+@findex SUCCESS_EXIT_CODE
+@item SUCCESS_EXIT_CODE
+A C expression for the status code to be returned when the compiler
+exits without serious errors.
+
+@findex HOST_WORDS_BIG_ENDIAN
+@item HOST_WORDS_BIG_ENDIAN
+Defined if the host machine stores words of multi-word values in
+big-endian order. (GNU CC does not depend on the host byte ordering
+within a word.)
+
+@findex HOST_FLOAT_WORDS_BIG_ENDIAN
+@item HOST_FLOAT_WORDS_BIG_ENDIAN
+Define this macro to be 1 if the host machine stores @code{DFmode},
+@code{XFmode} or @code{TFmode} floating point numbers in memory with the
+word containing the sign bit at the lowest address; otherwise, define it
+to be zero.
+
+This macro need not be defined if the ordering is the same as for
+multi-word integers.
+
+@findex HOST_FLOAT_FORMAT
+@item HOST_FLOAT_FORMAT
+A numeric code distinguishing the floating point format for the host
+machine. See @code{TARGET_FLOAT_FORMAT} in @ref{Storage Layout} for the
+alternatives and default.
+
+@findex HOST_BITS_PER_CHAR
+@item HOST_BITS_PER_CHAR
+A C expression for the number of bits in @code{char} on the host
+machine.
+
+@findex HOST_BITS_PER_SHORT
+@item HOST_BITS_PER_SHORT
+A C expression for the number of bits in @code{short} on the host
+machine.
+
+@findex HOST_BITS_PER_INT
+@item HOST_BITS_PER_INT
+A C expression for the number of bits in @code{int} on the host
+machine.
+
+@findex HOST_BITS_PER_LONG
+@item HOST_BITS_PER_LONG
+A C expression for the number of bits in @code{long} on the host
+machine.
+
+@findex ONLY_INT_FIELDS
+@item ONLY_INT_FIELDS
+Define this macro to indicate that the host compiler only supports
+@code{int} bit fields, rather than other integral types, including
+@code{enum}, as do most C compilers.
+
+@findex OBSTACK_CHUNK_SIZE
+@item OBSTACK_CHUNK_SIZE
+A C expression for the size of ordinary obstack chunks.
+If you don't define this, a usually-reasonable default is used.
+
+@findex OBSTACK_CHUNK_ALLOC
+@item OBSTACK_CHUNK_ALLOC
+The function used to allocate obstack chunks.
+If you don't define this, @code{xmalloc} is used.
+
+@findex OBSTACK_CHUNK_FREE
+@item OBSTACK_CHUNK_FREE
+The function used to free obstack chunks.
+If you don't define this, @code{free} is used.
+
+@findex USE_C_ALLOCA
+@item USE_C_ALLOCA
+Define this macro to indicate that the compiler is running with the
+@code{alloca} implemented in C. This version of @code{alloca} can be
+found in the file @file{alloca.c}; to use it, you must also alter the
+@file{Makefile} variable @code{ALLOCA}. (This is done automatically
+for the systems on which we know it is needed.)
+
+If you do define this macro, you should probably do it as follows:
+
+@example
+#ifndef __GNUC__
+#define USE_C_ALLOCA
+#else
+#define alloca __builtin_alloca
+#endif
+@end example
+
+@noindent
+so that when the compiler is compiled with GNU CC it uses the more
+efficient built-in @code{alloca} function.
+
+@item FUNCTION_CONVERSION_BUG
+@findex FUNCTION_CONVERSION_BUG
+Define this macro to indicate that the host compiler does not properly
+handle converting a function value to a pointer-to-function when it is
+used in an expression.
+
+@findex HAVE_VPRINTF
+@findex vprintf
+@item HAVE_VPRINTF
+Define this if the library function @code{vprintf} is available on your
+system.
+
+@findex MULTIBYTE_CHARS
+@item MULTIBYTE_CHARS
+Define this macro to enable support for multibyte characters in the
+input to GNU CC. This requires that the host system support the ANSI C
+library functions for converting multibyte characters to wide
+characters.
+
+@findex HAVE_PUTENV
+@findex putenv
+@item HAVE_PUTENV
+Define this if the library function @code{putenv} is available on your
+system.
+
+@findex POSIX
+@item POSIX
+Define this if your system is POSIX.1 compliant.
+
+@findex HAVE_POPEN
+@findex popen
+@item HAVE_POPEN
+Define this if the library function @code{popen} is available on your
+system.
+
+@findex NO_SYS_SIGLIST
+@item NO_SYS_SIGLIST
+Define this if your system @emph{does not} provide the variable
+@code{sys_siglist}.
+
+@findex DONT_DECLARE_SYS_SIGLIST
+@item DONT_DECLARE_SYS_SIGLIST
+Define this if your system has the variable @code{sys_siglist}, and
+there is already a declaration of it in the system header files.
+
+@findex USE_PROTOTYPES
+@item USE_PROTOTYPES
+Define this to be 1 if you know that the host compiler supports
+prototypes, even if it doesn't define __STDC__, or define
+it to be 0 if you do not want any prototypes used in compiling
+GNU CC. If @samp{USE_PROTOTYPES} is not defined, it will be
+determined automatically whether your compiler supports
+prototypes by checking if @samp{__STDC__} is defined.
+
+@findex NO_MD_PROTOTYPES
+@item NO_MD_PROTOTYPES
+Define this if you wish suppression of prototypes generated from
+the machine description file, but to use other prototypes within
+GNU CC. If @samp{USE_PROTOTYPES} is defined to be 0, or the
+host compiler does not support prototypes, this macro has no
+effect.
+
+@findex MD_CALL_PROTOTYPES
+@item MD_CALL_PROTOTYPES
+Define this if you wish to generate prototypes for the
+@code{gen_call} or @code{gen_call_value} functions generated from
+the machine description file. If @samp{USE_PROTOTYPES} is
+defined to be 0, or the host compiler does not support
+prototypes, or @samp{NO_MD_PROTOTYPES} is defined, this macro has
+no effect. As soon as all of the machine descriptions are
+modified to have the appropriate number of arguments, this macro
+will be removed.
+
+@vindex sys_siglist
+Some systems do provide this variable, but with a different name such
+as @code{_sys_siglist}. On these systems, you can define
+@code{sys_siglist} as a macro which expands into the name actually
+provided.
+
+@findex NO_STAB_H
+@item NO_STAB_H
+Define this if your system does not have the include file
+@file{stab.h}. If @samp{USG} is defined, @samp{NO_STAB_H} is
+assumed.
+
+@findex PATH_SEPARATOR
+@item PATH_SEPARATOR
+Define this macro to be a C character constant representing the
+character used to separate components in paths. The default value is.
+the colon character
+
+@findex DIR_SEPARATOR
+@item DIR_SEPARATOR
+If your system uses some character other than slash to separate
+directory names within a file specification, define this macro to be a C
+character constant specifying that character. When GNU CC displays file
+names, the character you specify will be used. GNU CC will test for
+both slash and the character you specify when parsing filenames.
+
+@findex OBJECT_SUFFIX
+@item OBJECT_SUFFIX
+Define this macro to be a C string representing the suffix for object
+files on your machine. If you do not define this macro, GNU CC will use
+@samp{.o} as the suffix for object files.
+
+@findex EXECUTABLE_SUFFIX
+@item EXECUTABLE_SUFFIX
+Define this macro to be a C string representing the suffix for executable
+files on your machine. If you do not define this macro, GNU CC will use
+the null string as the suffix for object files.
+
+@findex COLLECT_EXPORT_LIST
+@item COLLECT_EXPORT_LIST
+If defined, @code{collect2} will scan the individual object files
+specified on its command line and create an export list for the linker.
+Define this macro for systems like AIX, where the linker discards
+object files that are not referenced from @code{main} and uses export
+lists.
+@end table
+
+@findex bzero
+@findex bcmp
+In addition, configuration files for system V define @code{bcopy},
+@code{bzero} and @code{bcmp} as aliases. Some files define @code{alloca}
+as a macro when compiled with GNU CC, in order to take advantage of the
+benefit of GNU CC's built-in @code{alloca}.

+@findex MULTILIB_OPTIONS
+@item MULTILIB_OPTIONS
+For some targets, invoking GNU CC in different ways produces objects

+produces both big and little endian code. For these targets, you must
+arrange for multiple versions of @file{libgcc.a} to be compiled, one for

+procedure will build all combinations of compatible options.
+
+For example, if you set @code{MULTILIB_OPTIONS} to @samp{m68000/m68020
+msoft-float}, @file{Makefile} will build special versions of
+@file{libgcc.a} using the sets of options @samp{-m68000}, @samp{-m68020},
+@samp{-msoft-float}, @samp{-m68000 -msoft-float}, and @samp{-m68020
+-msoft-float}.
+
+@findex MULTILIB_DIRNAMES
+@item MULTILIB_DIRNAMES
+If @code{MULTILIB_OPTIONS} is used, this variable specifies the
+directory names that should be used to hold the various libraries.
+Write one element in @code{MULTILIB_DIRNAMES} for each element in
+@code{MULTILIB_OPTIONS}. If @code{MULTILIB_DIRNAMES} is not used, the
+default value will be @code{MULTILIB_OPTIONS}, with all slashes treated
+as spaces.
+
+For example, if @code{MULTILIB_OPTIONS} is specified as @samp{m68000/m68020
+msoft-float}, then the default value of @code{MULTILIB_DIRNAMES} is
+@samp{m68000 m68020 msoft-float}. You may specify a different value if
+you desire a different set of directory names.
+
+@findex MULTILIB_MATCHES
+@item MULTILIB_MATCHES
+Sometimes the same option may be written in two different ways. If an
+option is listed in @code{MULTILIB_OPTIONS}, GNU CC needs to know about
+any synonyms. In that case, set @code{MULTILIB_MATCHES} to a list of
+items of the form @samp{option=option} to describe all relevant
+synonyms. For example, @samp{m68000=mc68000 m68020=mc68020}.
+
+@findex MULTILIB_EXCEPTIONS
+@item MULTILIB_EXCEPTIONS
+Sometimes when there are multiple sets of @code{MULTILIB_OPTIONS} being
+specified, there are combinations that should not be built. In that
+case, set @code{MULTILIB_EXCEPTIONS} to be all of the switch exceptions
+in shell case syntax that should not be built.
+
+For example, in the PowerPC embedded ABI support, it was not desirable
+to build libraries that compiled with the @samp{-mcall-aixdesc} option
+and either of the @samp{-mcall-aixdesc} or @samp{-mlittle} options at
+the same time, and therefore @code{MULTILIB_EXCEPTIONS} is set to
+@code{*mrelocatable/*mcall-aixdesc* *mlittle/*mcall-aixdesc*}.
+
+@findex MULTILIB_EXTRA_OPTS
+@item MULTILIB_EXTRA_OPTS
+Sometimes it is desirable that when building multiple versions of
+@file{libgcc.a} certain options should always be passed on to the
+compiler. In that case, set @code{MULTILIB_EXTRA_OPTS} to be the list
+of options to be used for all builds.

+@node Funding
+@unnumbered Funding Free Software
+
+If you want to have more free software a few years from now, it makes
+sense for you to help encourage people to contribute funds for its
+development. The most effective approach known is to encourage
+commercial redistributors to donate.
+
+Users of free software systems can boost the pace of development by
+encouraging for-a-fee distributors to donate part of their selling price
+to free software developers---the Free Software Foundation, and others.
+
+The way to convince distributors to do this is to demand it and expect
+it from them. So when you compare distributors, judge them partly by
+how much they give to free software development. Show distributors
+they must compete to be the one who gives the most.
+
+To make this approach work, you must insist on numbers that you can
+compare, such as, ``We will donate ten dollars to the Frobnitz project
+for each disk sold.'' Don't be satisfied with a vague promise, such as
+``A portion of the profits are donated,'' since it doesn't give a basis
+for comparison.
+
+Even a precise fraction ``of the profits from this disk'' is not very
+meaningful, since creative accounting and unrelated business decisions
+can greatly alter what fraction of the sales price counts as profit.
+If the price you pay is $50, ten percent of the profit is probably
+less than a dollar; it might be a few cents, or nothing at all.
+
+Some redistributors do development work themselves. This is useful too;
+but to keep everyone honest, you need to inquire how much they do, and
+what kind. Some kinds of development make much more long-term
+difference than others. For example, maintaining a separate version of
+a program contributes very little; maintaining the standard version of a
+program for the whole community contributes much. Easy new ports
+contribute little, since someone else would surely do them; difficult
+ports such as adding a new CPU to the GNU C compiler contribute more;
+major new features or packages contribute the most.
+
+By establishing the idea that supporting further development is ``the
+proper thing to do'' when distributing free software for a fee, we can
+assure a steady flow of resources into making more free software.

+@quotation
+@i{This section is a political message from the League for Programming
+Freedom to the users of GNU CC. We have included it here because the
+issue of interface copyright is important to the GNU project.}
+@end quotation
+
+Apple, Lotus, and now CDC have tried to create a new form of legal
+monopoly: a copyright on a user interface.
+
+An interface is a kind of language---a set of conventions for
+communication between two entities, human or machine. Until a few years
+ago, the law seemed clear: interfaces were outside the domain of
+copyright, so programmers could program freely and implement whatever
+interface the users demanded. Imitating de-facto standard interfaces,
+sometimes with improvements, was standard practice in the computer
+field. These improvements, if accepted by the users, caught on and
+became the norm; in this way, much progress took place.
+
+Computer users, and most software developers, were happy with this state
+of affairs. However, large companies such as Apple and Lotus would
+prefer a different system---one in which they can own interfaces and
+thereby rid themselves of all serious competitors. They hope that
+interface copyright will give them, in effect, monopolies on major
+classes of software.
+
+Other large companies such as IBM and Digital also favor interface
+monopolies, for the same reason: if languages become property, they
+expect to own many de-facto standard languages. But Apple and Lotus are
+the ones who have actually sued. Apple's lawsuit was defeated, for
+reasons only partly related to the general issue of interface copyright.
+
+Lotus won lawsuits against two small companies, which were thus put out
+of business. Then Lotus sued Borland; Lotus won in the trial court (no
+surprise, since it was the same court that had ruled for Lotus twice
+before), but the court of appeals ruled in favor of Borland, which was
+assisted by a friend-of-the-court brief from the League for Programming
+Freedom.
+
+Lotus appealed the case to the Supreme Court, which heard the case but
+was unable to reach a decision. This failure means that the appeals
+court decision stands, in one portion of the United States, and may
+influence the other appeals courts, but it does not set a nationwide
+precedent. The battle is not over, and it is not limited to the United
+States.
+
+The battle is extending into other areas of software as well. In 1995 a
+company that produced a simulator for a CDC computer was shut down by a
+copyright lawsuit, in which CDC charged that the simulator infringed the
+copyright on the manuals for the computer.
+
+If the monopolists get their way, they will hobble the software field:
+
+@itemize @bullet
+@item
+Gratuitous incompatibilities will burden users. Imagine if each car
+manufacturer had to design a different way to start, stop, and steer a
+car.
+
+@item
+Users will be ``locked in'' to whichever interface they learn; then they
+will be prisoners of one supplier, who will charge a monopolistic price.
+
+@item
+Large companies have an unfair advantage wherever lawsuits become
+commonplace. Since they can afford to sue, they can intimidate smaller
+developers with threats even when they don't really have a case.
+
+@item
+Interface improvements will come slower, since incremental evolution
+through creative partial imitation will no longer occur.
+@end itemize
+
+If interface monopolies are accepted, other large companies are waiting
+to grab theirs:
+
+@itemize @bullet
+@item
+Adobe is expected to claim a monopoly on the interfaces of various
+popular application programs, if Lotus ultimately wins the case against
+Borland.
+
+@item
+Open Computing magazine reported a Microsoft vice president as threatening
+to sue people who imitate the interface of Windows.
+@end itemize
+
+Users invest a great deal of time and money in learning to use computer
+interfaces. Far more, in fact, than software developers invest in
+developing @emph{and even implementing} the interfaces. Whoever can own
+an interface, has made its users into captives, and misappropriated
+their investment.
+
+To protect our freedom from monopolies like these, a group of
+programmers and users have formed a grass-roots political organization,
+the League for Programming Freedom.
+
+The purpose of the League is to oppose monopolistic practices such as
+interface copyright and software patents. The League calls for a return
+to the legal policies of the recent past, in which programmers could
+program freely. The League is not concerned with free software as an
+issue, and is not affiliated with the Free Software Foundation.
+
+The League's activities include publicizing the issues, as is being done
+here, and filing friend-of-the-court briefs on behalf of defendants sued
+by monopolists.
+
+The League's membership rolls include Donald Knuth, the foremost
+authority on algorithms, John McCarthy, inventor of Lisp, Marvin Minsky,
+founder of the MIT Artificial Intelligence lab, Guy L. Steele, Jr.,
+author of well-known books on Lisp and C, as well as Richard Stallman,
+the developer of GNU CC. Please join and add your name to the list.
+Membership dues in the League are $42 per year for programmers, managers
+and professionals; $10.50 for students; $21 for others.
+
+Activist members are especially important, but members who have no time
+to give are also important. Surveys at major ACM conferences have
+indicated a vast majority of attendees agree with the League on both
+issues (interface copyrights and software patents). If just ten percent
+of the programmers who agree with the League join the League, we will
+probably triumph.

+
+@display
+Copyright @copyright{} 1989, 1991 Free Software Foundation, Inc.
+59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+@end display
+
+@unnumberedsec Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software---to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.

+@center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+@end ifinfo
+
+@enumerate 0
+@item
+This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The ``Program'', below,
+refers to any such program or work, and a ``work based on the Program''
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term ``modification''.) Each licensee is addressed as ``you''.
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+@item
+You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+@item
+You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+@enumerate a
+@item
+You must cause the modified files to carry prominent notices
+stating that you changed the files and the date of any change.
+
+@item
+You must cause any work that you distribute or publish, that in
+whole or in part contains or is derived from the Program or any
+part thereof, to be licensed as a whole at no charge to all third
+parties under the terms of this License.
+
+@item
+If the modified program normally reads commands interactively
+when run, you must cause it, when started running for such
+interactive use in the most ordinary way, to print or display an
+announcement including an appropriate copyright notice and a
+notice that there is no warranty (or else, saying that you provide
+a warranty) and that users may redistribute the program under
+these conditions, and telling the user how to view a copy of this
+License. (Exception: if the Program itself is interactive but
+does not normally print such an announcement, your work based on
+the Program is not required to print an announcement.)
+@end enumerate
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+@item
+You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+@enumerate a
+@item
+Accompany it with the complete corresponding machine-readable
+source code, which must be distributed under the terms of Sections
+1 and 2 above on a medium customarily used for software interchange; or,
+
+@item
+Accompany it with a written offer, valid for at least three
+years, to give any third party, for a charge no more than your
+cost of physically performing source distribution, a complete
+machine-readable copy of the corresponding source code, to be
+distributed under the terms of Sections 1 and 2 above on a medium
+customarily used for software interchange; or,
+
+@item
+Accompany it with the information you received as to the offer
+to distribute corresponding source code. (This alternative is
+allowed only for noncommercial distribution and only if you
+received the program in object code or executable form with such
+an offer, in accord with Subsection b above.)
+@end enumerate
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+@item
+You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+@item
+You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+@item
+Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+@item
+If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+@item
+If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+@item
+The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and ``any
+later version'', you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+@item
+If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and

+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least

+@item -fprofile-arcs
+Instrument @dfn{arcs} during compilation. For each function of your
+program, GNU CC creates a program flow graph, then finds a spanning tree
+for the graph. Only arcs that are not on the spanning tree have to be
+instrumented: the compiler adds code to count the number of times that these
+arcs are executed. When an arc is the only exit or only entrance to a
+block, the instrumentation code can be added to the block; otherwise, a
+new basic block must be created to hold the instrumentation code.
+
+Since not every arc in the program must be instrumented, programs
+compiled with this option run faster than programs compiled with
+@samp{-a}, which adds instrumentation code to every basic block in the
+program. The tradeoff: since @code{gcov} does not have
+execution counts for all branches, it must start with the execution
+counts for the instrumented branches, and then iterate over the program
+flow graph until the entire graph has been solved. Hence, @code{gcov}
+runs a little more slowly than a program which uses information from
+@samp{-a}.
+
+@samp{-fprofile-arcs} also makes it possible to estimate branch
+probabilities, and to calculate basic block execution counts. In
+general, basic block execution counts do not give enough information to
+estimate all branch probabilities. When the compiled program exits, it
+saves the arc execution counts to a file called

Position-independent code requires special support, and therefore works
only on certain machines. For the 386, GNU CC supports PIC for System V
but not for the Sun 386i. Code generated for the IBM RS/6000 is always
position-independent.

+@item -fcheck-memory-usage
+Generate extra code to check each memory access. GNU CC will generate
+code that is suitable for a detector of bad memory accesses such as
+@file{Checker}. If you specify this option, you can not use the
+@code{asm} or @code{__asm__} keywords.
+
+You must also specify this option when you compile functions you call that
+have side effects. If you do not, you may get erronous messages from
+the detector. Normally, you should compile all your code with this option.
+If you use functions from a library that have side-effects (such as
+@code{read}), you may not be able to recompile the library and
+specify this option. In that case, you can enable the
+@samp{-fprefix-function-name} option, which requests GNU CC to encapsulate
+your code and make other functions look as if they were compiled with
+@samp{-fcheck-memory-usage}. This is done by calling ``stubs'',
+which are provided by the detector. If you cannot find or build
+stubs for every function you call, you may have to specify
+@samp{-fcheck-memory-usage} without @samp{-fprefix-function-name}.
+
+@item -fprefix-function-name
+Request GNU CC to add a prefix to the symbols generated for function names.
+GNU CC adds a prefix to the names of functions defined as well as
+functions called. Code compiled with this option and code compiled

+@node Stack Checking
+@subsection Specifying How Stack Checking is Done
+
+GNU CC will check that stack references are within the boundaries of
+the stack, if the @samp{-fstack-check} is specified, in one of three ways:
+
+@enumerate
+@item
+If the value of the @code{STACK_CHECK_BUILTIN} macro is nonzero, GNU CC
+will assume that you have arranged for stack checking to be done at
+appropriate places in the configuration files, e.g., in
+@code{FUNCTION_PROLOGUE}. GNU CC will do not other special processing.
+
+@item
+If @code{STACK_CHECK_BUILTIN} is zero and you defined a named pattern
+called @code{check_stack} in your @file{md} file, GNU CC will call that
+pattern with one argument which is the address to compare the stack
+value against. You must arrange for this pattern to report an error if
+the stack pointer is out of range.
+
+@item
+If neither of the above are true, GNU CC will generate code to periodically
+``probe'' the stack pointer using the values of the macros defined below.
+@end enumerate
+
+Normally, you will use the default values of these macros, so GNU CC
+will use the third approach.
+
+@table @code
+@findex STACK_CHECK_BUILTIN
+@item STACK_CHECK_BUILTIN
+A nonzero value if stack checking is done by the configuration files in a
+machine-dependent manner. You should define this macro if stack checking
+is require by the ABI of your machine or if you would like to have to stack
+checking in some more efficient way than GNU CC's portable approach.
+The default value of this macro is zero.
+
+@findex STACK_CHECK_PROBE_INTERVAL
+@item STACK_CHECK_PROBE_INTERVAL
+An integer representing the interval at which GNU CC must generate stack
+probe instructions. You will normally define this macro to be no larger
+than the size of the ``guard pages'' at the end of a stack area. The
+default value of 4096 is suitable for most systems.
+
+@findex STACK_CHECK_PROBE_LOAD
+@item STACK_CHECK_PROBE_LOAD
+A integer which is nonzero if GNU CC should perform the stack probe
+as a load instruction and zero if GNU CC should use a store instruction.
+The default is zero, which is the most efficient choice on most systems.
+
+@findex STACK_CHECK_PROTECT
+@item STACK_CHECK_PROTECT
+The number of bytes of stack needed to recover from a stack overflow,
+for languages where such a recovery is supported. The default value of
+75 words should be adequate for most machines.
+
+@findex STACK_CHECK_MAX_FRAME_SIZE
+@item STACK_CHECK_MAX_FRAME_SIZE
+The maximum size of a stack frame, in bytes. GNU CC will generate probe
+instructions in non-leaf functions to ensure at least this many bytes of
+stack are available. If a stack frame is larger than this size, stack
+checking will not be reliable and GNU CC will issue a warning. The
+default is chosen so that GNU CC only generates one instruction on most
+systems. You should normally not change the default value of this macro.
+
+@findex STACK_CHECK_FIXED_FRAME_SIZE
+@item STACK_CHECK_FIXED_FRAME_SIZE
+GNU CC uses this value to generate the above warning message. It
+represents the amount of fixed frame used by a function, not including
+space for any callee-saved registers, temporaries and user variables.
+You need only specify an upper bound for this amount and will normally
+use the default of four words.
+
+@findex STACK_CHECK_MAX_VAR_SIZE
+@item STACK_CHECK_MAX_VAR_SIZE
+The maximum size, in bytes, of an object that GNU CC will place in the
+fixed area of the stack frame when the user specifies
+@samp{-fstack-check}.
+GNU CC computed the default from the values of the above macros and you will
+normally not need to override that default.
