-IMPORTANT: After applying this patch, you must rebuild the
-Info documentation derived from the Texinfo files in the
-gcc distribution, as this patch does not include patches
-to any derived files (due to differences in the way gcc
-version 2.7.2.2 is obtained by users). Use the following
-command sequence after applying this patch:
-
- cd gcc-2.7.2.2; make -f Makefile.in gcc.info
-
-If that fails due to `makeinfo' not being installed, obtain
-texinfo-3.11.tar.gz from a GNU distribution site, unpack,
-build, and install it, and try the above command sequence
-again.

-*** 1,2 ****
---- 1,244 ----
-+ Sun Aug 10 18:14:24 1997 Craig Burley <burley@gnu.ai.mit.edu>
-+
-+ Integrate C front end part of patch for better alias
-+ handling from John Carr <jfc@mit.edu>:
-+ * c-decl.c (grokdeclarator): Check for RID_RESTRICT
-+ flag; diagnose certain misuses; set DECL_RESTRICT as
-+ appropriate.
-+ * c-lex.c (init_lex): Set up RID_RESTRICT pointer.
-+ Unset `restrict' as reserved word.
-+ * c-lex.h: Replace RID_NOALIAS with RID_RESTRICT.
-+ * c-parse.gperf: Add `restrict' and `__restrict'
-+ keywords.
-+ * tree.h: Add DECL_RESTRICT flag.
-+
-+ Sun Aug 10 14:50:30 1997 Jim Wilson <wilson@cygnus.com>
-+
-+ * sdbout.c (plain_type_1, case ARRAY_TYPE): Verify that TYPE_DOMAIN
-+ has integer TYPE_{MAX,MIN}_VALUE before using them.
-+
-+ Mon Jul 28 15:35:38 1997 Craig Burley <burley@gnu.ai.mit.edu>
-+
-+ * combine.c (num_sign_bit_copies): Speed up the 961126-1.c
-+ case of repeated (neg (neg (neg ...))) so c-torture runs
-+ in less time.
-+
-+ * reload.c (find_reloads_toplev, find_reloads_address):
-+ These now return whether replacement by a constant, so
-+ caller can know to do other replacements. Currently if
-+ caller doesn't want that info and such replacement would
-+ happen, we crash so as to investigate the problem and
-+ learn more about it. All callers updated.
-+ (find_reloads): If pseudo replaced by constant, always
-+ update duplicates of it.
-+
-+ Mon Jul 21 00:00:24 1997 Craig Burley <burley@gnu.ai.mit.edu>
-+
-+ * fold-const.c (size_binop): Make sure overflows
-+ are flagged properly, so as to avoid silently generating
-+ bad code for, e.g., a too-large array.
-+
-+ Sun Jul 13 22:23:14 1997 Craig Burley <burley@gnu.ai.mit.edu>
-+
-+ * stmt.c (expand_expr_stmt): Must generate code for
-+ statements within an expression (gcc's `({ ... )}')
-+ even if -fsyntax-only.
-+
-+ Mon Jun 30 17:23:07 1997 Michael Meissner <meissner@cygnus.com>
-+
-+ * gcc.c (process_command): If -save-temps and -pipe were specified
-+ together, don't do -pipe.
-+
-+ Thu Jun 26 05:40:46 1997 Craig Burley <burley@gnu.ai.mit.edu>
-+
-+ * stor-layout.c (get_best_mode): Handle negative bitpos
-+ correctly, so caller doesn't get into infinite recursion
-+ trying to cope with a spurious VOIDmode.
-+
-+ Tue Jun 24 19:46:31 1997 Craig Burley <burley@gnu.ai.mit.edu>
-+
-+ * varasm.c (assemble_variable): If low part of size
-+ doesn't fit in an int, variable is too large.
-+
-+ Sat Jun 21 12:09:00 1997 Craig Burley <burley@gnu.ai.mit.edu>
-+
-+ * toplev.c (rest_of_compilation): Also temporarily set
-+ flag_unroll_all_loops to 0 during first of two calls
-+ to loop_optimize, and clean up code a bit to make it
-+ easier to read.
-+
-+ * expr.c (safe_from_p_1, safe_from_p): Fix these to use
-+ TREE_SET_CODE instead of TREE_CODE.
-+
-+ Thu Jun 19 19:30:47 1997 Craig Burley <burley@gnu.ai.mit.edu>
-+
-+ * config/alpha/alpha.c: Don't include <stamp.h> on
-+ GNU Linux machines.
-+
-+ * config/alpha/elf.c: New file for ELF systems.
-+
-+ * config/alpha/xm-alpha.h: Don't declare alloca()
-+ if it's already a macro (probably defined in stdlib.h).
-+
-+ * config/alpha/xm-linux.h (HAVE_STRERROR): #define
-+ this, according to what various people suggest.
-+
-+ * config.guess, configure: Make some (hopefully safe)
-+ changes, based mostly on gcc-2.8.0-in-development,
-+ in the hopes that these make some systems configure
-+ "out of the box" more easily, especially Alpha systems.
-+
-+ Mon Jun 9 04:26:53 1997 Craig Burley <burley@gnu.ai.mit.edu>
-+
-+ * expr.c (safe_from_p): Don't examine a given SAVE_EXPR
-+ node more than once, to avoid combinatorial explosion
-+ in complex expressions. Fortran case that triggered
-+ this had a complicated *and* complex expression with
-+ 293 unique nodes, resulting in 28 minutes of compile
-+ time mostly spent in a single top-level safe_from_p()
-+ call due to all the redundant SAVE_EXPR traversals.
-+ This change reduced the time to around 2 seconds.
-+ (safe_from_p_1): New helper function that does almost
-+ exactly what the old safe_from_p() did.
-+
-+ Sun May 18 21:18:48 1997 Craig Burley <burley@gnu.ai.mit.edu>
-+
-+ * fold-const.c (fold): Clarify why TRUNC_DIV_EXPR
-+ and FLOOR_DIV_EXPR aren't rewritten to EXACT_DIV_EXPR,
-+ clean up related code.
-+
-+ Sat May 3 13:53:00 1997 Craig Burley <burley@gnu.ai.mit.edu>
-+
-+ * config.sub: Change all `i[345]' to `i[3456]' to
-+ support Pentium Pro (this change was already made
-+ in configure for gcc-2.7.2.2).
-+
-+ From Toon Moene <toon@moene.indiv.nluug.nl>:
-+ * toplev.c (rest_of_compilation): Unroll loops
-+ only the final time through loop optimization.
-+
-+ Sun Apr 20 10:45:35 1997 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
-+
-+ * final.c (profile_function): Only call ASM_OUTPUT_REG_{PUSH,POP}
-+ if defined.
-+
-+ Wed Apr 16 22:26:16 1997 Craig Burley <burley@gnu.ai.mit.edu>
-+
-+ * alias.c, cse.c, loop.c, rtl.c, rtl.h, sched.c:
-+ Make changes submitted by <jfc@mit.edu>.
-+
-+ Sun Apr 13 19:32:53 1997 Craig Burley <burley@gnu.ai.mit.edu>
-+
-+ * fold-const.c (fold): If extra warnings enabled,
-+ warn about integer division by zero.
-+
-+ Sun Apr 13 08:15:31 1997 Bernd Schmidt <crux@Pool.Informatik.RWTH-Aachen.DE>
-+
-+ * final.c (profile_function): Save the static chain register
-+ around the call to the profiler function.
-+
-+ Sat Apr 12 14:56:42 1997 Craig Burley <burley@gnu.ai.mit.edu>
-+
-+ * unroll.c (find_splittable_givs): Permit more cases
-+ of mult_val/add_val to agree by using rtx_equal_p
-+ to compare them instead of requiring them to be
-+ integers with the same value. Also don't bother
-+ checking if ADDRESS_COST not defined (they will be
-+ equal in that case).
-+
-+ Fri Apr 11 03:30:04 1997 Craig Burley <burley@gnu.ai.mit.edu>
-+
-+ * unroll.c (find_splittable_givs): Must create a new
-+ register if the mult_val and add_val fields don't
-+ agree.
-+
-+ Fri Apr 4 23:00:55 1997 Craig Burley <burley@gnu.ai.mit.edu>
-+
-+ * fold-const.c (fold): Don't call multiple_of_p if
-+ arg1 is constant zero, to avoid crashing; simplify
-+ code accordingly.
-+
-+ Wed Feb 26 13:09:33 1997 Michael Meissner <meissner@cygnus.com>
-+
-+ * reload.c (debug_reload): Fix format string to print
-+ reload_nocombine[r].
-+
-+ Sun Feb 23 15:26:53 1997 Craig Burley <burley@gnu.ai.mit.edu>
-+
-+ * fold-const.c (multiple_of_p): Clean up and improve.
-+ (fold): Clean up invocation of multiple_of_p.
-+
-+ Sat Feb 8 04:53:27 1997 Craig Burley <burley@gnu.ai.mit.edu>
-+
-+ From <jfc@jfc.tiac.net> Fri, 07 Feb 1997 22:02:21 -0500:
-+ * alias.c (init_alias_analysis): Reduce amount of time
-+ needed to simplify the reg_base_value array in the
-+ typical case (especially involving function inlining).
-+
-+ Fri Jan 10 17:22:17 1997 Craig Burley <burley@gnu.ai.mit.edu>
-+
-+ Minor improvements/fixes to better alias handling:
-+ * Makefile.in (alias.o): Fix typo in rule (was RLT_H).
-+ * cse.c, sched.c: Fix up some indenting.
-+ * toplev.c: Add -fargument-alias flag, so Fortran users
-+ can turn C-style aliasing on once g77 defaults to
-+ -fargument-noalias-global.
-+
-+ Integrate patch for better alias handling from
-+ John Carr <jfc@mit.edu>:
-+ * Makefile.in (OBJS, alias.o): New module and rule.

-+
-+ Fri Jan 3 04:01:00 1997 Craig Burley <burley@gnu.ai.mit.edu>
-+

-+
-+ * config/alpha/alpha.md: Fix pattern that matches if_then_else

-+ An example of the sort of thing we care about (at this point --
-+ this routine could surely be made more general, and expanded
-+ to do what the *_DIV_EXPR's fold() cases do now) is discovering
-+ that
-+
-+ SAVE_EXPR (I) * SAVE_EXPR (J * 8)
-+
-+ is a multiple of
-+
-+ SAVE_EXPR (J * 8)
-+
-+ when we know that the two `SAVE_EXPR (J * 8)' nodes are the
-+ same node (which means they will have the same value at run
-+ time, even though we don't know when they'll be assigned).
-+
-+ This code also handles discovering that
-+
-+ SAVE_EXPR (I) * SAVE_EXPR (J * 8)
-+
-+ is a multiple of
-+
-+ 8
-+
-+ (of course) so we don't have to worry about dealing with a
-+ possible remainder.
-+
-+ Note that we _look_ inside a SAVE_EXPR only to determine
-+ how it was calculated; it is not safe for fold() to do much
-+ of anything else with the internals of a SAVE_EXPR, since
-+ fold() cannot know when it will be evaluated at run time.
-+ For example, the latter example above _cannot_ be implemented
-+ as
-+
-+ SAVE_EXPR (I) * J
-+
-+ or any variant thereof, since the value of J at evaluation time
-+ of the original SAVE_EXPR is not necessarily the same at the time
-+ the new expression is evaluated. The only optimization of this
-+ sort that would be valid is changing
-+
-+ SAVE_EXPR (I) * SAVE_EXPR (SAVE_EXPR (J) * 8)
-+ divided by
-+ 8
-+
-+ to

-+ An integer division by zero is detected.
-+
-+ Some cases of division by zero might occur as the result
-+ of using so-called ``safe'' macros.
-+ For example:
-+
-+ @smallexample
-+ #define BUCKETS(b) (((b) != NULL) ? (b)->buckets : 0)
-+ @dots{...}
-+ i = j / BUCKETS(b);
-+ @end smallexample
-+
-+ Although analysis of the context of the above code could
-+ prove that @samp{b} is never null when it is executed,
-+ the division-by-zero warning is still useful, because
-+ @code{gcc} generates code to do the division by zero at
-+ run time so as to generate a run-time fault,
-+ and tidy programmers will want to find ways to prevent
-+ this needless code from being generated.
-+
-+ Note that @code{gcc} transforms expressions so as to find
-+ opportunities for performing expensive operations
-+ (such as division) at compile time instead of generating
-+ code to perform them at run time.
-+ For example, @code{gcc} transforms:
-+
-+ @smallexample
-+ 2 / (i == 0)
-+ @end smallexample
-+
-+ into:
-+
-+ @smallexample
-+ (i == 0) ? (2 / 1) : (2 / 0)
-+ @end smallexample
-+
-+ As a result, the division-by-zero warning might occur
-+ in contexts where the divisor seems to be a non-constant.
-+ It is useful in this case as well, because programmers might want
-+ to clean up the code so the compiled code does not include
-+ dead code to divide by zero.

-+ @samp{-fargument-noalias-global} specifies that arguments do not
-+ alias each other and do not alias global storage.
-+
-+ For code written in C, C++, and Objective-C, @samp{-fargument-alias}
-+ is the default.
-+ For code written in Fortran, @samp{-fargument-noalias-global} is
-+ the default, though this is pertinent only on systems where
-+ @code{g77} is installed.
-+ (See the documentation for other compilers for information on the
-+ defaults for their respective languages.)
-+
-+ Normally, @code{gcc} assumes that a write through a pointer
-+ passed as a parameter to the current function might modify a
-+ value pointed to by another pointer passed as a parameter, or
-+ in global storage.
-+
-+ For example, consider this code:
-+
-+ @example
-+ void x(int *i, int *j)
-+ @{
-+ extern int k;
-+
-+ ++*i;
-+ ++*j;
-+ ++k;
-+ @}
-+ @end example
-+
-+ When compiling the above function, @code{gcc} assumes that @samp{i} might
-+ be a pointer to the same variable as @samp{j}, and that either @samp{i},
-+ @samp{j}, or both might be a pointer to @samp{k}.
-+
-+ Therefore, @code{gcc} does not assume it can generate code to read
-+ @samp{*i}, @samp{*j}, and @samp{k} into separate registers, increment
-+ each register, then write the incremented values back out.
-+
-+ Instead, @code{gcc} must generate code that reads @samp{*i},
-+ increments it, and writes it back before reading @samp{*j},
-+ in case @samp{i} and @samp{j} are aliased, and, similarly,
-+ that writes @samp{*j} before reading @samp{k}.
-+ The result is code that, on many systems, takes longer to execute,
-+ due to the way many processors schedule instruction execution.
-+
-+ Compiling the above code with the @samp{-fargument-noalias} option
-+ allows @code{gcc} to assume that @samp{i} and @samp{j} do not alias
-+ each other, but either might alias @samp{k}.
-+
-+ Compiling the above code with the @samp{-fargument-noalias-global}
-+ option allows @code{gcc} to assume that no combination of @samp{i},
-+ @samp{j}, and @samp{k} are aliases for each other.
-+
-+ @emph{Note:} Use the @samp{-fargument-noalias} and
-+ @samp{-fargument-noalias-global} options with care.
-+ While they can result in faster executables, they can
-+ also result in executables with subtle bugs, bugs that
-+ show up only when compiled for specific target systems,
-+ or bugs that show up only when compiled by specific versions
-+ of @code{g77}.

-/* This is the file containing the verbage for the

-
- DEFDOC (IMP, SUMMARY, DESCRIPTION)
-
- IMP is the implementation keyword used in the intrin module.
- SUMMARY is the short summary to go in the "* Menu:" section
- of the Info document. DESCRIPTION is the longer description
- to go in the documentation itself.
-
- Note that IMP is leveraged across multiple intrinsic names.
-
- To make for more accurate and consistent documentation,
- the translation made by intdoc.c of the text in SUMMARY
- and DESCRIPTION includes the special sequence
-
- @ARGNO@
-
- where ARGNO is a series of digits forming a number that
- is substituted by intdoc.c as follows:
-
- 0 The initial-caps form of the intrinsic name (e.g. Float).
- 1-98 The initial-caps form of the ARGNO'th argument.
- 99 (SUMMARY only) a newline plus the appropriate # of spaces.
-
- Hope this info is enough to encourage people to feel free to
- add documentation to this file!

- already (bit 1). Consistently produce a clear diagnostic
- in cases of recursive I/O. Avoid infinite recursion in

- happened.

-
-May 7 1997 Daniel Pettet <dan.pettet@bchydro.bc.ca>
-

-
- * Version 0.5.20 released.
-
-Wed Feb 26 20:28:53 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * Makefile.in: $(MAKE) invocations now explicitly
- specify `-f Makefile', just in case the `makefile's
- from the netlib distribution would get used instead.
-
-Mon Feb 24 16:43:39 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * libU77/Makefile.in (check): Specify driver, and
- don't bother enabling already-enabled intrinsic groups.
- Also, get the $(srcdir) version of u77-test.f.
-
-Sat Feb 22 14:08:42 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * libU77/u77-test.f: Explicitly declare intrinsics, get
- rid of useless CHARACTER declarations on intrinsics (maybe
- someday appropriate to implement meaning of that in g77
- and restore them?).
- Add spin loop just to fatten up the timings a bit.
- Clarify ETIME output as having three fields.
- Call TIME with CHARACTER*8, not CHARACTER*6, argument.
- Call new SECOND intrinsic subroutine, after calling
- new DUMDUM subroutine just to ensure the correct value

-
-Thu Feb 20 15:22:42 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * libU77/bes.c: Comment out all the code, as g77 avoids actually

-
-Mon Feb 17 02:27:41 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * libU77/fgetc_.c (fgetc_): Allow return value to be

-
-Tue Feb 11 14:12:19 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * Makefile.in: Clarify role of $(srcdir) here. Fix

- use it directly.
- (${srcdir}/configure, ${srcdir}/libU77/configure):
- Remove the config.cache files in build directory before
- cd'ing to source directory as well.

-
- INTEGER*8 support built in to f2c.h and libf2c (since
- gcc will be used to compile relevant code anyway):
- * Makefile.in, libF77/Makefile.in: Add pow_qq.o,
- qbitbits.o, and qbitshft.o to $POW and $F90BIT macros,
- as appropriate.
- * f2c.h.in: Define appropriate types and macros.
- Place #error directive correctly.
- * configure.in: Determine appropriate types for long
- integer (F2C_LONGINT).
- Meanwhile, quote strings in #error, for consistency.
- Fix restoring of ac_cpp macro.
- * configure: Regenerated using autoconf-2.12.
-
- * libF77/Version.c, libI77/Version.c, libU77/Version.c:
- Update version numbers.
- Change names and code for g77-specific version-printing
- routines (shorter names should be safer to link on
- weird, 8-char systems).
-
- * libF77/c_cos.c, libF77/c_div.c, libF77/c_exp.c,
- libF77/c_log.c, libF77/c_sin.c, libF77/c_sqrt.c,
- libF77/d_cnjg.c, libF77/pow_zi.c, libF77/r_cnjg.c,
- libF77/z_cos.c, libF77/z_div.c, libF77/z_exp.c,
- libF77/z_log.c, libF77/z_sin.c, libF77/z_sqrt.c:
- Changed to work properly even when result is aliased
- with any inputs.
-
- * libF77/makefile, libI77/makefile: Leave these in
- the g77 distribution, so it is easier to track changes
- to official libf2c.
-
- * libF77/signal_.c: Eliminate redundant `return 0;'.
-
- * libI77/fio.h (err, errfl): Fix these so they work
- (and must be expressed) as statements.
- Fix up many users of err() to include trailing semicolon.
-
- * Incorporate changes by Bell Labs to libf2c through 1997-02-07.
-
-1997-02-06 Dave Love <d.love@dl.ac.uk>
-
- * libU77/etime_.c, libU77/dtime_.c: Fix getrusage stuff.
-
- * libU77/config.h.in: Regenerate for HAVE_GETRUSAGE.
-
- * libU77/Makefile.in, libI77/Makefile.in, libF77/Makefile.in:
- Redo *clean targets; distclean and maintainer-clean remove the stage?
- and include links. This probably want looking at further.
-
-Wed Feb 5 00:21:23 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- Add libU77 library from Dave Love <d.love@dl.ac.uk>:
- * Makefile.in: Add libU77 directory, rules, etc.
- * configure.in: New libU77 directory, Makefile, etc.
-
- * Makefile.in, libF77/Makefile.in, libI77/Makefile.in,
- libU77/Makefile.in: Reorganize these so $(AR) commands
- handled by the top-level Makefile instead of the
- subordinates. This permits it to do $(AR) only when
- one or more object files actually change, instead of
- having to force-update it as was necessary before.
- And that had the disadvantage of requiring, e.g., user
- root to have access to $(AR) to the library simply to
- install g77, which might be problematic on an NFS setup.
- (mostlyclean, clean, distclean, maintainer-clean):
- Properly handle these rules.
-
- * Makefile.in: Don't invoke config.status here -- let
- compiler-level stuff handle all that.
-
- * err.c [MISSING_FILE_ELEMS]: Declare malloc in this case
- too, so it doesn't end up as an integer.
-
-Sat Feb 1 02:43:48 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * libF77/Makefile.in: More fixup for $(F90BIT) -- wasn't
- in list for ar command, and it wasn't correctly listed
- in the list of things depending on f2c.h.
-
- * f2c.h.in: Fix up #error directive.
-
-1997-01-31 Dave Love <d.love@dl.ac.uk>
-
- * libF77/Makefile.in ($(lib)): Add $(F90BIT); shouldn't exclude
- stuff f2c needs so we can share the library.
-
-Sat Jan 18 19:39:03 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * configure.in: No longer define ALWAYS_FLUSH, the
- resulting performance is too low.
-
-Wed Dec 18 12:06:02 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- Patch from Mumit Khan <khan@xraylith.wisc.edu>:

- of version information.
-
- * libI77/Makefile.in (OBJ): Add ftell_.o to list of objects.
-
- * libI77/uio.c (do_ud): Fix up casts in PAD_UDread case just
- like they were fixed in the other case.
-
-Thu Oct 31 22:27:45 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- * libI77/ftell_.c (fseek_): Map incoming whence argument to
- system's actual SEEK_CUR, SEEK_SET, or SEEK_END macro for
- fseek(), and crash (gracefully) if the argument is invalid.
-
-1996-10-19 Dave Love <d.love@dl.ac.uk>
-
- * configure.in: Add check that we have the tools to cross-compile
- if appropriate.
- (NO_EOF_CHAR_CHECK,Skip_f2c_Undefs): Define.
-
- * libF77/Makefile.in (F90BIT): New routines from Netlib.
-
- * f2c.h.in:
- Use more sanitary #error (indented for K&R compliance if necessary) if
- f2c_i2 defined.
- Sync with Netlib: Add `uninteger'. (Commented out) integer*8 stuff.
- bit_{test,clear,set} macros.
-
-1996-10-19 Dave Love <d.love@dl.ac.uk>
-
- Update to Netlib version of 1996-09-26.

-
-Sat Nov 18 19:37:22 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * Version 0.5.17 released.

-
-Fri Sep 22 02:19:59 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * libI77/backspace.c, libI77/close.c, libI77/endfile.c,
- libI77/fio.h, libI77/inquire.c, libI77/rawio.h,
- libF77/s_paus.c: Not an MSDOS system if GO32
- is defined, in the sense that the run-time environment
- is thus more UNIX-like.
-
-Wed Sep 20 02:24:51 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * libF77/Makefile.in, libI77/Makefile.in: Comment out `ld -r -x'
- and `mv' line pairs, since `-x' isn't supported on systems

-
- * Version 0.5.16 released.

-Mon Aug 28 12:50:34 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * libF77/Makefile.in, libI77/Makefile.in ($(lib)): Force ar'ing
- and ranlib'ing of libf2c.a, else after rm'ing libf2c.a and
- doing a make, only libI77 or libF77 would be added to
- the newly created archive.
- Also, instead of `$?' list all targets explicitly so all
- objects are updated in libf2c.a even if only one actually
- needs recompiling, for similar reason -- we can't easily tell
- if a given object is really up-to-date in libf2c.a, or even
- present there.
-
-Sun Aug 27 14:54:24 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * libF77/Makefile.in, libI77/Makefile.in: Fix spacing so
- initial tabs are present in all appropriate places.
- Move identical $(AR) commands in if then/else clauses
- to single command preceding if.
- (.c.o, Version[FI].o): Use $@ instead of $* because AIX (RS/6000)
- says $@ means source, not object, basename, and $@ seems to work
- everywhere.
-
-Wed Aug 23 15:44:25 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * libF77/system_.c (system_): Declare as returning `ftnint',
- consistent with signal_, instead of defaulting to `int'.
- Hope dmg@research.att.com agrees, else probably will
- change to whatever he determines is correct (and change
- g77 accordingly).
-
-Thu Aug 17 08:46:17 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * libI77/rsne.c (s_rsne): Call f_init if not already done.

-Wed Aug 16 17:33:06 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * libF77/Makefile.in, libI77/Makefile.in (CFLAGS): Put -g1
- after configured CFLAGS but before GCC_CFLAGS, so by default
- the libraries are built with minimal debugging information.
-
-Fri Jul 28 10:30:15 1995 Dave Love <d.love@dl.ac.uk>
-
- * libI77/open.c (f_open): Call f_init if not already done.
-
-Sat Jul 1 19:31:56 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * libF77/system_.c (system_): Make buff one byte bigger so

- string.
-
-Tue Jun 27 23:28:16 1995 Craig Burley (burley@gnu.ai.mit.edu)

-
- * libI77/Version.c (__G77_LIBI77_VERSION__): Add this string
- to track g77 mods to libf2c.
-
- * libI77/rawio.h: #include <rawio.h> only conditionally,

-This directory contains the f2c library packaged for use with g77 to configure
-and build automatically (in principle!) as part of the top-level configure and
-make steps. This depends on the makefile and configure fragments in ../f.
-
-Some small changes have been made to the f2c distributions of lib[FI]77 which
-come from <ftp:bell-labs.com/netlib/f2c/> and are maintained (excellently) by
-David M. Gay <dmg@bell-labs.com>. See the Notice files for copyright
-information. I'll try to get the changes rolled into the f2c distribution.
-
-Files that come directly from netlib are either maintained in the
-gcc/f/runtime/ directory under their original names or, if they
-are not pertinent for g77's version of libf2c, under their original
-names with `.netlib' appended. For example, gcc/f/runtime/permissions.netlib
-is a copy of f2c's top-level`permissions' file in the netlib distribution.
-In this case, it applies only to the relevant portions of the libF77/ and
-libI77/ directories; it does not apply to the libU77/ directory, which is
-distributed under different licensing arrangements. Similarly,
-the `makefile.netlib' files in libF77/ and libI77/ are copies of
-the respective `makefile' files in the netlib distribution, but
-are not used when building g77's version of libf2c.
-
-The `README.netlib' files in libF77/ and libI77/ thus might be
-interesting, but should not be taken as guidelines for how to
-configure and build libf2c in g77's distribution.
-
-The packaging for auto-configuration was done by Dave Love <d.love@dl.ac.uk>.
-Minor changes have been made by James Craig Burley <burley@gnu.ai.mit.edu>,
-who probably broke things Dave had working. :-)
-
-Among the user-visible changes (choices) g77 makes in its
-version of libf2c:
-
-- f2c.h configured to default to padding unformatted direct reads
- (#define Pad_UDread), because that's the behavior most users
- expect.
-
-- f2c.h configured to default to outputting leading zeros before
- decimal points in formatted and list-directed output, to be compatible
- with many other compilers (#define WANT_LEAD_0). Either way is
- standard-conforming, however, and you should try to avoid writing
- code that assumes one format or another.
-
-- dtime_() and etime_() are from Dave Love's libU77, not from
- netlib's libF77.

-TODO list for the g77 library
-
-* `Makefile.in's should be brought up to standard; I'm not sure they
- have a complete set of targets at present.
-
-* Investigate building shared libraries on systems we know about
- (probably in 0.5.22, using libtool-1.0 from the FSF, which looks
- quite useful).
-
-* Test cases.
-
-* Allow the library to be stripped to save space.
-
-* An interface to IEEE maths functions from libc where this makes
- sense.

-31 Aug. 1989:
- 1. A(min(i,j)) now is translated correctly (where A is an array).
- 2. 7 and 8 character variable names are allowed (but elicit a
- complaint under -ext).
- 3. LOGICAL*1 is treated as LOGICAL, with just one error message
- per LOGICAL*1 statement (rather than one per variable declared
- in that statement). [Note that LOGICAL*1 is not in Fortran 77.]
- Like f77, f2c now allows the format in a read or write statement
- to be an integer array.
-
-5 Sept. 1989:
- Fixed botch in argument passing of substrings of equivalenced
-variables.
-
-15 Sept. 1989:
- Warn about incorrect code generated when a character-valued
-function is not declared external and is passed as a parameter
-(in violation of the Fortran 77 standard) before it is invoked.
-Example:
-
- subroutine foo(a,b)
- character*10 a,b
- call goo(a,b)
- b = a(3)
- end
-
-18 Sept. 1989:
- Complain about overlapping initializations.
-
-20 Sept. 1989:
- Warn about names declared EXTERNAL but never referenced;
-include such names as externs in the generated C (even
-though most C compilers will discard them).
-
-24 Sept. 1989:
- New option -w8 to suppress complaint when COMMON or EQUIVALENCE
-forces word alignment of a double.
- Under -A (for ANSI C), ensure that floating constants (terminated
-by 'f') contain either a decimal point or an exponent field.
- Repair bugs sometimes encountered with CHAR and ICHAR intrinsic
-functions.
- Restore f77's optimizations for copying and comparing character
-strings of length 1.
- Always assume floating-point valued routines in libF77 return
-doubles, even under -R.
- Repair occasional omission of arguments in routines having multiple
-entry points.
- Repair bugs in computing offsets of character strings involved
-in EQUIVALENCE.
- Don't omit structure qualification when COMMON variables are used
-as FORMATs or internal files.
-
-2 Oct. 1989:
- Warn about variables that appear only in data stmts; don't emit them.
- Fix bugs in character DATA for noncharacter variables
-involved in EQUIVALENCE.
- Treat noncharacter variables initialized (at least partly) with
-character data as though they were equivalenced -- put out a struct
-and #define the variables. This eliminates the hideous and nonportable
-numeric values that were used to initialize such variables.
- Treat IMPLICIT NONE as IMPLICIT UNDEFINED(A-Z) .
- Quit when given invalid options.
-
-8 Oct. 1989:
- Modified naming scheme for generated intermediate variables;
-more are recycled, fewer distinct ones used.
- New option -W nn specifies nn characters/word for Hollerith
-data initializing non-character variables.
- Bug fix: x(i:min(i+10,j)) used to elicit "Can't handle opcode 31 yet".
- Integer expressions of the form (i+const1) - (i+const2), where
-i is a scalar integer variable, are now simplified to (const1-const2);
-this leads to simpler translation of some substring expressions.
- Initialize uninitialized portions of character string arrays to 0
-rather than to blanks.
-
-9 Oct. 1989:
- New option -c to insert comments showing original Fortran source.
- New option -g to insert line numbers of original Fortran source.
-
-10 Oct. 1989:
- ! recognized as in-line comment delimiter (a la Fortran 88).
-
-24 Oct. 1989:
- New options to ease coping with systems that want the structs
-that result from COMMON blocks to be defined just once:
- -E causes uninitialized COMMON blocks to be declared Extern;
-if Extern is undefined, f2c.h #defines it to be extern.
- -ec causes a separate .c file to be emitted for each
-uninitialized COMMON block: COMMON /ABC/ yields abc_com.c;
-thus one can compile *_com.c into a library to ensure
-precisely one definition.
- -e1c is similar to -ec, except that everything goes into
-one file, along with comments that give a sed script for
-splitting the file into the pieces that -ec would give.
-This is for use with netlib's "execute f2c" service (for which
--ec is coerced into -e1c, and the sed script will put everything
-but the COMMON definitions into f2c_out.c ).
-
-28 Oct. 1989:
- Convert "i = i op ..." into "i op= ...;" even when i is a
-dummy argument.
-
-13 Nov. 1989:
- Name integer constants (passed as arguments) c__... rather
-than c_... so
- common /c/stuff
- call foo(1)
- ...
-is translated correctly.
-
-19 Nov. 1989:
- Floating-point constants are now kept as strings unless they
-are involved in constant expressions that get simplified. The
-floating-point constants kept as strings can have arbitrarily
-many significant figures and a very large exponent field (as
-large as long int allows on the machine on which f2c runs).
-Thus, for example, the body of
-
- subroutine zot(x)
- double precision x(6), pi
- parameter (pi=3.1415926535897932384626433832795028841972)
- x(1) = pi
- x(2) = pi+1
- x(3) = 9287349823749272.7429874923740978492734D-298374
- x(4) = .89
- x(5) = 4.0005
- x(6) = 10D7
- end
-
-now gets translated into
-
- x[1] = 3.1415926535897932384626433832795028841972;

- x[5] = (float)4.0004999999999997;
- x[6] = 100000000.;
-
- Recognition of f77 machine-constant intrinsics deleted, i.e.,
-epbase, epprec, epemin, epemax, eptiny, ephuge, epmrsp.
-
-22 Nov. 1989:
- Workarounds for glitches on some Sun systems...
- libf77: libF77/makefile modified to point out possible need
-to compile libF77/main.c with -Donexit=on_exit .
- libi77: libI77/wref.c (and libI77/README) modified so non-ANSI
-systems can compile with USE_STRLEN defined, which will cause
- sprintf(b = buf, "%#.*f", d, x);
- n = strlen(b) + d1;
-rather than
- n = sprintf(b = buf, "%#.*f", d, x) + d1;
-to be compiled.
-
-26 Nov. 1989:
- Longer names are now accepted (up to 50 characters); names may
-contain underscores (in which case they will have two underscores
-appended, to avoid clashes with library names).
-
-28 Nov. 1989:
- libi77 updated:
- 1. Allow 3 (or, on Crays, 4) digit exponents under format Ew.d .
- 2. Try to get things right on machines where ints have 16 bits.
-
-29 Nov. 1989:
- Supplied missing semicolon in parameterless subroutines that
-have multiple entry points (all of them parameterless).
-
-30 Nov. 1989:
- libf77 and libi77 revised to use types from f2c.h.
- f2c now types floating-point valued C library routines as "double"
-rather than "doublereal" (for use with nonstandard C compilers for
-which "double" is IEEE double extended).
-
-1 Dec. 1989:
- f2c.h updated to eliminate #defines rendered unnecessary (and,
-indeed, dangerous) by change of 26 Nov. to long names possibly
-containing underscores.
- libi77 further revised: yesterday's change omitted two tweaks to fmt.h
-(tweaks which only matter if float and real or double and doublereal are
-different types).
-
-2 Dec. 1989:
- Better error message (than "bad tag") for NAMELIST, which no longer
-inhibits C output.
-
-4 Dec. 1989:
- Allow capital letters in hex constants (f77 extension; e.g.,
-x'a012BCd', X'A012BCD' and x'a012bcd' are all treated as the integer
-167848909).
- libi77 further revised: lio.c lio.h lread.c wref.c wrtfmt.c tweaked
-again to allow float and real or double and doublereal to be different.
-
-6 Dec. 1989:
- Revised f2c.h -- required for the following...
- Simpler looking translations for abs, min, max, using #defines in
-revised f2c.h .
- libi77: more corrections to types; additions for NAMELIST.
- Corrected casts in some I/O calls.
- Translation of NAMELIST; libi77 must still be revised. Currently
-libi77 gives you a run-time error message if you attempt NAMELIST I/O.
-
-7 Dec. 1989:
- Fixed bug that prevented local integer variables that appear in DATA
-stmts from being ASSIGNed statement labels.
- Fillers (for DATA statements initializing EQUIVALENCEd variables and
-variables in COMMON) typed integer rather than doublereal (for slightly
-more portability, e.g. to Crays).
- libi77: missing return values supplied in a few places; some tests
-reordered for better working on the Cray.
- libf77: better accuracy for complex divide, complex square root,
-real mod function (casts to double; double temporaries).
-
-9 Dec. 1989:
- Fixed bug that caused needless (albeit harmless) empty lines to be
-inserted in the C output when a comment line contained trailing blanks.
- Further tweak to type of fillers: allow doublereal fillers if the
-struct has doublereal data.
-
-11 Dec. 1989:
- Alteration of rule for producing external (C) names from names that
-contain underscores. Now the external name is always obtained by
-appending a pair of underscores.
-
-12 Dec. 1989:
- C production inhibited after most errors.
-
-15 Dec. 1989:
- Fixed bug in headers for subroutines having two or more character
-strings arguments: the length arguments were reversed.
-
-19 Dec. 1989:
- f2c.h libf77 libi77: adjusted so #undefs in f2c.h should not foil
-compilation of libF77 and libI77.
- libf77: getenv_ adjusted to work with unsorted environments.
- libi77: the iostat= specifier should now work right with internal I/O.
-
-20 Dec. 1989:
- f2c bugs fixed: In the absence of an err= specifier, the iostat=
-specifier was generally set wrong. Character strings containing
-explicit nulls (\0) were truncated at the first null.
- Unlabeled DO loops recognized; must be terminated by ENDDO.
-(Don't ask for CYCLE, EXIT, named DO loops, or DO WHILE.)
-
-29 Dec. 1989:
- Nested unlabeled DO loops now handled properly; new warning for
-extraneous text at end of FORMAT.
-
-30 Dec. 1989:
- Fixed bug in translating dble(real(...)), dble(sngl(...)), and
-dble(float(...)), where ... is either of type double complex or
-is an expression requiring assignment to intermediate variables (e.g.,
-dble(real(foo(x+1))), where foo is a function and x is a variable).
-Regard nonblank label fields on continuation lines as an error.
-
-3 Jan. 1990:
- New option -C++ yields output that should be understood
-by C++ compilers.
-
-6 Jan. 1989:
- -a now excludes variables that appear in a namelist from those
-that it makes automatic. (As before, it also excludes variables
-that appear in a common, data, equivalence, or save statement.)
- The syntactically correct Fortran
- read(*,i) x
- end
-now yields syntactically correct C (even though both the Fortran
-and C are buggy -- no FORMAT has not been ASSIGNed to i).
-
-7 Jan. 1990:
- libi77: routines supporting NAMELIST added. Surrounding quotes
-made optional when no ambiguity arises in a list or namelist READ
-of a character-string value.
-
-9 Jan. 1990:
- f2c.src made available.
-
-16 Jan. 1990:
- New options -P to produce ANSI C or C++ prototypes for procedures
-defined. Change to -A and -C++: f2c tries to infer prototypes for
-invoked procedures unless the new -!P option is given. New warning
-messages for inconsistent calling sequences among procedures within
-a single file. Most of f2c/src is affected.
- f2c.h: typedefs for procedure arguments added; netlib's f2c service
-will insert appropriate typedefs for use with older versions of f2c.h.
-
-17 Jan. 1990:
- f2c/src: defs.h exec.c format.c proc.c putpcc.c version.c xsum0.out
-updated. Castargs and protofile made extern in defs.h; exec.c
-modified so superfluous else clauses are diagnosed; unused variables
-omitted from declarations in format.c proc.c putpcc.c .
-
-21 Jan. 1990:
- No C emitted for procedures declared external but not referenced.
- f2c.h: more new types added for use with -P.
- New feature: f2c accepts as arguments files ending in .p or .P;
-such files are assumed to be prototype files, such as produced by
-the -P option. All prototype files are read before any Fortran files
-and apply globally to all Fortran files. Suitable prototypes help f2c
-warn about calling-sequence errors and can tell f2c how to type
-procedures declared external but not explicitly typed; the latter is
-mainly of interest for users of the -A and -C++ options. (Prototype
-arguments are not available to netlib's "execute f2c" service.)
- New option -it tells f2c to try to infer types of untyped external
-arguments from their use as parameters to prototyped or previously
-defined procedures.
- f2c/src: many minor cleanups; most modules changed. Individual
-files in f2c/src are now in "bundle" format. The former f2c.1 is
-now f2c.1t; "f2c.1t from f2c" and "f2c.1t from f2c/src" are now the
-same, as are "f2c.1 from f2c" and "f2c.1 from f2c/src". People who
-do not obtain a new copy of "all from f2c/src" should at least add
- fclose(sortfp);
-after the call on do_init_data(outfile, sortfp) in format_data.c .
-
-22 Jan. 1990:
- Cleaner man page wording (thanks to Doug McIlroy).
- -it now also applies to all untyped EXTERNAL procedures, not just
-arguments.
-
-23 Jan. 01:34:00 EST 1990:
- Bug fixes: under -A and -C++, incorrect C was generated for
-subroutines having multiple entries but no arguments.
- Under -A -P, subroutines of no arguments were given prototype
-calling sequence () rather than (void).
- Character-valued functions elicited erroneous warning messages
-about inconsistent calling sequences when referenced by another
-procedure in the same file.
- f2c.1t: omit first appearance of libF77.a in FILES section;
-load order of libraries is -lF77 -lI77, not vice versa (bug
-introduced in yesterday's edits); define .F macro for those whose
--man lacks it. (For a while after yesterday's fixes were posted,
-f2c.1t was out of date. Sorry!)
-
-23 Jan. 9:53:24 EST 1990:
- Character substring expressions involving function calls having
-character arguments (including the intrinsic len function) yielded
-incorrect C.
- Procedures defined after invocation (in the same file) with
-conflicting argument types also got an erroneous message about
-the wrong number of arguments.
-
-24 Jan. 11:44:00 EST 1990:
- Bug fixes: -p omitted #undefs; COMMON block names containing
-underscores had their C names incorrectly computed; a COMMON block
-having the name of a previously defined procedure wreaked havoc;
-if all arguments were .P files, f2c tried reading the second as a
-Fortran file.
- New feature: -P emits comments showing COMMON block lengths, so one
-can get warnings of incompatible COMMON block lengths by having f2c
-read .P (or .p) files. Now by running f2c twice, first with -P -!c
-(or -P!c), then with *.P among the arguments, you can be warned of
-inconsistent COMMON usage, and COMMON blocks having inconsistent
-lengths will be given the maximum length. (The latter always did
-happen within each input file; now -P lets you extend this behavior
-across files.)
-
-26 Jan. 16:44:00 EST 1990:
- Option -it made less aggressive: untyped external procedures that
-are invoked are now typed by the rules of Fortran, rather than by
-previous use of procedures to which they are passed as arguments
-before being invoked.
- Option -P now includes information about references, i.e., called
-procedures, in the prototype files (in the form of special comments).
-This allows iterative invocations of f2c to infer more about untyped
-external names, particularly when multiple Fortran files are involved.
- As usual, there are some obscure bug fixes:
-1. Repair of erroneous warning messages about inconsistent number of
-arguments that arose when a character dummy parameter was discovered
-to be a function or when multiple entry points involved character
-variables appearing in a previous entry point.
-2. Repair of memory fault after error msg about "adjustable character
-function".
-3. Under -U, allow MAIN_ as a subroutine name (in the same file as a
-main program).
-4. Change for consistency: a known function invoked as a subroutine,
-then as a function elicits a warning rather than an error.
-
-26 Jan. 22:32:00 EST 1990:
- Fixed two bugs that resulted in incorrect C for substrings, within
-the body of a character-valued function, of the function's name, when
-those substrings were arguments to another function (even implicitly,
-as in character-string assignment).
-
-28 Jan. 18:32:00 EST 1990:
- libf77, libi77: checksum files added; "make check" looks for
-transmission errors. NAMELIST read modified to allow $ rather than &
-to precede a namelist name, to allow $ rather than / to terminate
-input where the name of another variable would otherwise be expected,
-and to regard all nonprinting ASCII characters <= ' ' as spaces.
-
-29 Jan. 02:11:00 EST 1990:
- "fc from f2c" added.
- -it option made the default; -!it turns it off. Type information is
-now updated in a previously missed case.
- -P option tweaked again; message about when rerunning f2c may change
-prototypes or declarations made more accurate.
- New option -Ps implies -P and returns exit status 4 if rerunning
-f2c -P with prototype inputs might change prototypes or declarations.
-Now you can execute a crude script like
-
- cat *.f >zap.F
- rm -f zap.P
- while :; do
- f2c -Ps -!c zap.[FP]
- case $? in 4) ;; *) break;; esac
- done
-
-to get a file zap.P of the best prototypes f2c can determine for *.f .
-
-Jan. 29 07:30:21 EST 1990:
- Forgot to check for error status when setting return code 4 under -Ps;
-error status (1, 2, 3, or, for caught signal, 126) now takes precedence.
-
-Jan 29 14:17:00 EST 1990:
- Incorrect handling of
- open(n,'filename')
-repaired -- now treated as
- open(n,file='filename')
-(and, under -ext, given an error message).
- New optional source file memset.c for people whose systems don't
-provide memset, memcmp, and memcpy; #include <string.h> in mem.c
-changed to #include "string.h" so BSD people can create a local
-string.h that simply says #include <strings.h> .
-
-Jan 30 10:34:00 EST 1990:
- Fix erroneous warning at end of definition of a procedure with
-character arguments when the procedure had previously been called with
-a numeric argument instead of a character argument. (There were two
-warnings, the second one incorrectly complaining of a wrong number of
-arguments.)
-
-Jan 30 16:29:41 EST 1990:
- Fix case where -P and -Ps erroneously reported another iteration
-necessary. (Only harm is the extra iteration.)
-
-Feb 3 01:40:00 EST 1990:
- Supply semicolon occasionally omitted under -c .
- Try to force correct alignment when numeric variables are initialized
-with character data (a non-standard and non-portable practice). You
-must use the -W option if your code has such data statements and is
-meant to run on a machine with other than 4 characters/word; e.g., for
-code meant to run on a Cray, you would specify -W8 .
- Allow parentheses around expressions in output lists (in write and
-print statements).
- Rename source files so their names are <= 12 characters long
-(so there's room to append .Z and still have <= 14 characters);
-renamed files: formatdata.c niceprintf.c niceprintf.h safstrncpy.c .
- f2c material made available by anonymous ftp from research.att.com
-(look in dist/f2c ).
-
-Feb 3 03:49:00 EST 1990:
- Repair memory fault that arose from use (in an assignment or
-call) of a non-argument variable declared CHARACTER*(*).
-
-Feb 9 01:35:43 EST 1990:
- Fix erroneous error msg about bad types in
- subroutine foo(a,adim)
- dimension a(adim)
- integer adim
- Fix improper passing of character args (and possible memory fault)
-in the expression part of a computed goto.
- Fix botched calling sequences in array references involving
-functions having character args.
- Fix memory fault caused by invocation of character-valued functions
-of no arguments.
- Fix botched calling sequence of a character*1-valued function
-assigned to a character*1 variable.
- Fix bug in error msg for inconsistent number of args in prototypes.
- Allow generation of C output despite inconsistencies in prototypes,
-but give exit code 8.
- Simplify include logic (by removing some bogus logic); never
-prepend "/usr/include/" to file names.
- Minor cleanups (that should produce no visible change in f2c's
-behavior) in intr.c parse.h main.c defs.h formatdata.c p1output.c .
-
-Feb 10 00:19:38 EST 1990:
- Insert (integer) casts when floating-point expressions are used
-as subscripts.
- Make SAVE stmt (with no variable list) override -a .
- Minor cleanups: change field to Field in struct Addrblock (for the
-benefit of buggy C compilers); omit system("/bin/cp ...") in misc.c .
-
-Feb 13 00:39:00 EST 1990:
- Error msg fix in gram.dcl: change "cannot make %s parameter"
-to "cannot make into parameter".
-
-Feb 14 14:02:00 EST 1990:
- Various cleanups (invisible on systems with 4-byte ints), thanks
-to Dave Regan: vaxx.c eliminated; %d changed to %ld various places;
-external names adjusted for the benefit of stupid systems (that ignore
-case and recognize only 6 significant characters in external names);
-buffer shortened in xsum.c (e.g. for MS-DOS); fopen modes distinguish
-text and binary files; several unused functions eliminated; missing
-arg supplied to an unlikely fatalstr invocation.
-
-Thu Feb 15 19:15:53 EST 1990:
- More cleanups (invisible on systems with 4 byte ints); casts inserted
-so most complaints from cyntax(1) and lint(1) go away; a few (int)
-versus (long) casts corrected.
-
-Fri Feb 16 19:55:00 EST 1990:
- Recognize and translate unnamed Fortran 8x do while statements.
- Fix bug that occasionally caused improper breaking of character
-strings.
- New error message for attempts to provide DATA in a type-declaration
-statement.
-
-Sat Feb 17 11:43:00 EST 1990:
- Fix infinite loop clf -> Fatal -> done -> clf after I/O error.
- Change "if (addrp->vclass = CLPROC)" to "if (addrp->vclass == CLPROC)"
-in p1_addr (in p1output.c); this was probably harmless.
- Move a misplaced } in lex.c (which slowed initkey()).
- Thanks to Gary Word for pointing these things out.
-
-Sun Feb 18 18:07:00 EST 1990:
- Detect overlapping initializations of arrays and scalar variables
-in previously missed cases.
- Treat logical*2 as logical (after issuing a warning).
- Don't pass string literals to p1_comment().
- Correct a cast (introduced 16 Feb.) in gram.expr; this matters e.g.
-on a Cray.
- Attempt to isolate UNIX-specific things in sysdep.c (a new source
-file). Unless sysdep.c is compiled with SYSTEM_SORT defined, the
-intermediate files created for DATA statements are now sorted in-core
-without invoking system().
-
-Tue Feb 20 16:10:35 EST 1990:
- Move definition of binread and binwrite from init.c to sysdep.c .
- Recognize Fortran 8x tokens < <= == >= > <> as synonyms for
-.LT. .LE. .EQ. .GE. .GT. .NE.
- Minor cleanup in putpcc.c: fully remove simoffset().
- More discussion of system dependencies added to libI77/README.
-
-Tue Feb 20 21:44:07 EST 1990:
- Minor cleanups for the benefit of EBCDIC machines -- try to remove
-the assumption that 'a' through 'z' are contiguous. (Thanks again to
-Gary Word.) Also, change log2 to log_2 (shouldn't be necessary).
-
-Wed Feb 21 06:24:56 EST 1990:
- Fix botch in init.c introduced in previous change; only matters
-to non-ASCII machines.
-
-Thu Feb 22 17:29:12 EST 1990:
- Allow several entry points to mention the same array. Protect
-parameter adjustments with if's (for the case that an array is not
-an argument to all entrypoints).
- Under -u, allow
- subroutine foo(x,n)
- real x(n)
- integer n
- Compute intermediate variables used to evaluate dimension expressions
-at the right time. Example previously mistranslated:
- subroutine foo(x,k,m,n)
- real x(min(k,m,n))
- ...
- write(*,*) x
- Detect duplicate arguments. (The error msg points to the first
-executable stmt -- not wonderful, but not worth fixing.)
- Minor cleanup of min/max computation (sometimes slightly simpler).
-
-Sun Feb 25 09:39:01 EST 1990:
- Minor tweak to multiple entry points: protect parameter adjustments
-with if's only for (array) args that do not appear in all entry points.
- Minor tweaks to format.c and io.c (invisible unless your compiler
-complained at the duplicate #defines of IOSUNIT and IOSFMT or at
-comparisons of p1gets(...) with NULL).
-
-Sun Feb 25 18:40:10 EST 1990:
- Fix bug introduced Feb. 22: if a subprogram contained DATA and the
-first executable statement was labeled, then the label got lost.
-(Just change INEXEC to INDATA in p1output.c; it occurs just once.)
-
-Mon Feb 26 17:45:10 EST 1990:
- Fix bug in handling of " and ' in comments.
-
-Wed Mar 28 01:43:06 EST 1990:
-libI77:
- 1. Repair nasty I/O bug: opening two files and closing the first
-(after possibly reading or writing it), then writing the second caused
-the last buffer of the second to be lost.
- 2. Formatted reads of logical values treated all letters other than
-t or T as f (false).
- libI77 files changed: err.c rdfmt.c Version.c
- (Request "libi77 from f2c" -- you can't get these files individually.)
-
-f2c itself:
- Repair nasty bug in translation of
- ELSE IF (condition involving complicated abs, min, or max)
--- auxiliary statements were emitted at the wrong place.
- Supply semicolon previously omitted from the translation of a label
-(of a CONTINUE) immediately preceding an ELSE IF or an ELSE. This
-bug made f2c produce invalid C.
- Correct a memory fault that occurred (on some machines) when the
-error message "adjustable dimension on non-argument" should be given.
- Minor tweaks to remove some harmless warnings by overly chatty C
-compilers.
- Argument arays having constant dimensions but a variable lower bound
-(e.g., x(n+1:n+3)) had a * omitted from scalar arguments involved in
-the array offset computation.
-
-Wed Mar 28 18:47:59 EST 1990:
-libf77: add exit(0) to end of main [return(0) encounters a Cray bug]
-
-Sun Apr 1 16:20:58 EDT 1990:
- Avoid dereferencing null when processing equivalences after an error.
-
-Fri Apr 6 08:29:49 EDT 1990:
- Calls involving alternate return specifiers omitted processing
-needed for things like min, max, abs, and // (concatenation).
- INTEGER*2 PARAMETERs were treated as INTEGER*4.
- Convert some O(n^2) parsing to O(n).
-
-Tue Apr 10 20:07:02 EDT 1990:
- When inconsistent calling sequences involve differing numbers of
-arguments, report the first differing argument rather than the numbers
-of arguments.
- Fix bug under -a: formatted I/O in which either the unit or the
-format was a local character variable sometimes resulted in invalid C
-(a static struct initialized with an automatic component).
- Improve error message for invalid flag after elided -.
- Complain when literal table overflows, rather than infinitely
-looping. (The complaint mentions the new and otherwise undocumented
--NL option for specifying a larger literal table.)
- New option -h for forcing strings to word (or, with -hd, double-word)
-boundaries where possible.
- Repair a bug that could cause improper splitting of strings.
- Fix bug (cast of c to doublereal) in
- subroutine foo(c,r)
- double complex c
- double precision r
- c = cmplx(r,real(c))
- end
- New include file "sysdep.h" has some things from defs.h (and
-elsewhere) that one may need to modify on some systems.
- Some large arrays that were previously statically allocated are now
-dynamically allocated when f2c starts running.
- f2c/src files changed:
- README cds.c defs.h f2c.1 f2c.1t format.c formatdata.c init.c
- io.c lex.c main.c makefile mem.c misc.c names.c niceprintf.c
- output.c parse_args.c pread.c put.c putpcc.c sysdep.h
- version.c xsum0.out
-
-Wed Apr 11 18:27:12 EDT 1990:
- Fix bug in argument consistency checking of character, complex, and
-double complex valued functions. If the same source file contained a
-definition of such a function with arguments not explicitly typed,
-then subsequent references to the function might get erroneous
-warnings of inconsistent calling sequences.
- Tweaks to sysdep.h for partially ANSI systems.
- New options -kr and -krd cause f2c to use temporary variables to
-enforce Fortran evaluation-order rules with pernicious, old-style C
-compilers that apply the associative law to floating-point operations.
-
-Sat Apr 14 15:50:15 EDT 1990:
- libi77: libI77 adjusted to allow list-directed and namelist I/O
-of internal files; bug in namelist I/O of logical and character arrays
-fixed; list input of complex numbers adjusted to permit d or D to
-denote the start of the exponent field of a component.
- f2c itself: fix bug in handling complicated lower-bound
-expressions for character substrings; e.g., min and max did not work
-right, nor did function invocations involving character arguments.
- Switch to octal notation, rather than hexadecimal, for nonprinting
-characters in character and string constants.
- Fix bug (when neither -A nor -C++ was specified) in typing of
-external arguments of type complex, double complex, or character:
- subroutine foo(c)
- external c
- complex c
-now results in
- /* Complex */ int (*c) ();
-(as, indeed, it once did) rather than
- complex (*c) ();
-
-Sat Apr 14 22:50:39 EDT 1990:
- libI77/makefile: updated "make check" to omit lio.c
- lib[FI]77/makefile: trivial change: define CC = cc, reference $(CC).
- (Request, e.g., "libi77 from f2c" -- you can't ask for individual
-files from lib[FI]77.)
-
-Wed Apr 18 00:56:37 EDT 1990:
- Move declaration of atof() from defs.h to sysdep.h, where it is
-now not declared if stdlib.h is included. (NeXT's stdlib.h has a
-#define atof that otherwise wreaks havoc.)
- Under -u, provide a more intelligible error message (than "bad tag")
-for an attempt to define a function without specifying its type.
-
-Wed Apr 18 17:26:27 EDT 1990:
- Recognize \v (vertical tab) in Hollerith as well as quoted strings;
-add recognition of \r (carriage return).
- New option -!bs turns off recognition of escapes in character strings
-(\0, \\, \b, \f, \n, \r, \t, \v).
- Move to sysdep.c initialization of some arrays whose initialization
-assumed ASCII; #define Table_size in sysdep.h rather than using
-hard-coded 256 in allocating arrays of size 1 << (bits/byte).
-
-Thu Apr 19 08:13:21 EDT 1990:
- Warn when escapes would make Hollerith extend beyond statement end.
- Omit max() definition from misc.c (should be invisible except on
-systems that erroneously #define max in stdlib.h).
-
-Mon Apr 23 22:24:51 EDT 1990:
- When producing default-style C (no -A or -C++), cast switch
-expressions to (int).
- Move "-lF77 -lI77 -lm -lc" to link_msg, defined in sysdep.c .
- Add #define scrub(x) to sysdep.h, with invocations in format.c and
-formatdata.c, so that people who have systems like VMS that would
-otherwise create multiple versions of intermediate files can
-#define scrub(x) unlink(x)
-
-Tue Apr 24 18:28:36 EDT 1990:
- Pass string lengths once rather than twice to a function of character
-arguments involved in comparison of character strings of length 1.
-
-Fri Apr 27 13:11:52 EDT 1990:
- Fix bug that made f2c gag on concatenations involving char(...) on
-some systems.
-
-Sat Apr 28 23:20:16 EDT 1990:
- Fix control-stack bug in
- if(...) then
- else if (complicated condition)
- else
- endif
-(where the complicated condition causes assignment to an auxiliary
-variable, e.g., max(a*b,c)).
-
-Mon Apr 30 13:30:10 EDT 1990:
- Change fillers for DATA with holes from substructures to arrays
-(in an attempt to make things work right with C compilers that have
-funny padding rules for substructures, e.g., Sun C compilers).
- Minor cleanup of exec.c (should not affect generated C).
-
-Mon Apr 30 23:13:51 EDT 1990:
- Fix bug in handling return values of functions having multiple
-entry points of differing return types.
-
-Sat May 5 01:45:18 EDT 1990:
- Fix type inference bug in
- subroutine foo(x)
- call goo(x)
- end
- subroutine goo(i)
- i = 3
- end
-Instead of warning of inconsistent calling sequences for goo,
-f2c was simply making i a real variable; now i is correctly
-typed as an integer variable, and f2c issues an error message.
- Adjust error messages issued at end of declarations so they
-don't blame the first executable statement.
-
-Sun May 6 01:29:07 EDT 1990:
- Fix bug in -P and -Ps: warn when the definition of a subprogram adds
-information that would change prototypes or previous declarations.
-
-Thu May 10 18:09:15 EDT 1990:
- Fix further obscure bug with (default) -it: inconsistent calling
-sequences and I/O statements could interact to cause a memory fault.
-Example:
- SUBROUTINE FOO
- CALL GOO(' Something') ! Forgot integer first arg
- END
- SUBROUTINE GOO(IUNIT,MSG)
- CHARACTER*(*)MSG
- WRITE(IUNIT,'(1X,A)') MSG
- END
-
-Fri May 11 16:49:11 EDT 1990:
- Under -!c, do not delete any .c files (when there are errors).
- Avoid dereferencing 0 when a fatal error occurs while reading
-Fortran on stdin.
-
-Wed May 16 18:24:42 EDT 1990:
- f2c.ps made available.
-
-Mon Jun 4 12:53:08 EDT 1990:
- Diagnose I/O units of invalid type.
- Add specific error msg about dummy arguments in common.
-
-Wed Jun 13 12:43:17 EDT 1990:
- Under -A, supply a missing "[1]" for CHARACTER*1 variables that appear
-both in a DATA statement and in either COMMON or EQUIVALENCE.
-
-Mon Jun 18 16:58:31 EDT 1990:
- Trivial updates to f2c.ps . ("Fortran 8x" --> "Fortran 90"; omit
-"(draft)" from "(draft) ANSI C".)
-
-Tue Jun 19 07:36:32 EDT 1990:
- Fix incorrect code generated for ELSE IF(expression involving
-function call passing non-constant substring).
- Under -h, preserve the property that strings are null-terminated
-where possible.
- Remove spaces between # and define in lex.c output.c parse.h .
-
-Mon Jun 25 07:22:59 EDT 1990:
- Minor tweak to makefile to reduce unnecessary recompilations.
-
-Tue Jun 26 11:49:53 EDT 1990:
- Fix unintended truncation of some integer constants on machines
-where casting a long to (int) may change the value. E.g., when f2c
-ran on machines with 16-bit ints, "i = 99999" was being translated
-to "i = -31073;".
-
-Wed Jun 27 11:05:32 EDT 1990:
- Arrange for CHARACTER-valued PARAMETERs to honor their length
-specifications. Allow CHAR(nn) in expressions defining such PARAMETERs.
-
-Fri Jul 20 09:17:30 EDT 1990:
- Avoid dereferencing 0 when a FORMAT statement has no label.
-
-Thu Jul 26 11:09:39 EDT 1990:
- Remarks about VOID and binread,binwrite added to README.
- Tweaks to parse_args: should be invisible unless your compiler
-complained at (short)*store.
-
-Thu Aug 2 02:07:58 EDT 1990:
- f2c.ps: change the first line of page 5 from
- include stuff
-to
- include 'stuff'
-
-Tue Aug 14 13:21:24 EDT 1990:
- libi77: libI77 adjusted to treat tabs as spaces in list input.
-
-Fri Aug 17 07:24:53 EDT 1990:
- libi77: libI77 adjusted so a blank='ZERO' clause (upper case Z)
-in an open of a currently open file works right.
-
-Tue Aug 28 01:56:44 EDT 1990:
- Fix bug in warnings of inconsistent calling sequences: if an
-argument to a subprogram was never referenced, then a previous
-invocation of the subprogram (in the same source file) that
-passed something of the wrong type for that argument did not
-elicit a warning message.
-
-Thu Aug 30 09:46:12 EDT 1990:
- libi77: prevent embedded blanks in list output of complex values;
-omit exponent field in list output of values of magnitude between
-10 and 1e8; prevent writing stdin and reading stdout or stderr;
-don't close stdin, stdout, or stderr when reopening units 5, 6, 0.
-
-Tue Sep 4 12:30:57 EDT 1990:
- Fix bug in C emitted under -I2 or -i2 for INTEGER*4 FUNCTION.
- Warn of missing final END even if there are previous errors.
-
-Fri Sep 7 13:55:34 EDT 1990:
- Remark about "make xsum.out" and "make f2c" added to README.
-
-Tue Sep 18 23:50:01 EDT 1990:
- Fix null dereference (and, on some systems, writing of bogus *_com.c
-files) under -ec or -e1c when a prototype file (*.p or *.P) describes
-COMMON blocks that do not appear in the Fortran source.
- libi77:
- Add some #ifdef lines (#ifdef MSDOS, #ifndef MSDOS) to avoid
-references to stat and fstat on non-UNIX systems.
- On UNIX systems, add component udev to unit; decide that old
-and new files are the same iff both the uinode and udev components
-of unit agree.
- When an open stmt specifies STATUS='OLD', use stat rather than
-access (on UNIX systems) to check the existence of the file (in case
-directories leading to the file have funny permissions and this is
-a setuid or setgid program).
-
-Thu Sep 27 16:04:09 EDT 1990:
- Supply missing entry for Impldoblock in blksize array of cpexpr
-(in expr.c). No examples are known where this omission caused trouble.
-
-Tue Oct 2 22:58:09 EDT 1990:
- libf77: test signal(...) == SIG_IGN rather than & 01 in main().
- libi77: adjust rewind.c so two successive rewinds after a write
-don't clobber the file.
-
-Thu Oct 11 18:00:14 EDT 1990:
- libi77: minor cleanups: add #include "fcntl.h" to endfile.c, err.c,
-open.c; adjust g_char in util.c for segmented memories; in f_inqu
-(inquire.c), define x appropriately when MSDOS is defined.
-
-Mon Oct 15 20:02:11 EDT 1990:
- Add #ifdef MSDOS pointer adjustments to mem.c; treat NAME= as a
-synonym for FILE= in OPEN statements.
-
-Wed Oct 17 16:40:37 EDT 1990:
- libf77, libi77: minor cleanups: _cleanup() and abort() invocations
-replaced by invocations of sig_die in main.c; some error messages
-previously lost in buffers will now appear.
-
-Mon Oct 22 16:11:27 EDT 1990:
- libf77: separate sig_die from main (for folks who don't want to use
-the main in libF77).
- libi77: minor tweak to comments in README.
-
-Fri Nov 2 13:49:35 EST 1990:
- Use two underscores rather than one in generated temporary variable
-names to avoid conflict with COMMON names. f2c.ps updated to reflect
-this change and the NAME= extension introduced 15 Oct.
- Repair a rare memory fault in io.c .
-
-Mon Nov 5 16:43:55 EST 1990:
- libi77: changes to open.c (and err.c): complain if an open stmt
-specifies new= and the file already exists (as specified by Fortrans 77
-and 90); allow file= to be omitted in open stmts and allow
-status='replace' (Fortran 90 extensions).
-
-Fri Nov 30 10:10:14 EST 1990:
- Adjust malloc.c for unusual systems whose sbrk() can return values
-not properly aligned for doubles.
- Arrange for slightly more helpful and less repetitive warnings for
-non-character variables initialized with character data; these warnings
-are (still) suppressed by -w66.
-
-Fri Nov 30 15:57:59 EST 1990:
- Minor tweak to README (about changing VOID in f2c.h).
-
-Mon Dec 3 07:36:20 EST 1990:
- Fix spelling of "character" in f2c.1t.
-
-Tue Dec 4 09:48:56 EST 1990:
- Remark about link_msg and libf2c added to f2c/README.
-
-Thu Dec 6 08:33:24 EST 1990:
- Under -U, render label nnn as L_nnn rather than Lnnn.
-
-Fri Dec 7 18:05:00 EST 1990:
- Add more names from f2c.h (e.g. integer, real) to the c_keywords
-list of names to which an underscore is appended to avoid confusion.
-
-Mon Dec 10 19:11:15 EST 1990:
- Minor tweaks to makefile (./xsum) and README (binread/binwrite).
- libi77: a few modifications for POSIX systems; meant to be invisible
-elsewhere.
-
-Sun Dec 16 23:03:16 EST 1990:
- Fix null dereference caused by unusual erroneous input, e.g.
- call foo('abc')
- end
- subroutine foo(msg)
- data n/3/
- character*(*) msg
- end
-(Subroutine foo is illegal because the character statement comes after a
-data statement.)
- Use decimal rather than hex constants in xsum.c (to prevent
-erroneous warning messages about constant overflow).
-
-Mon Dec 17 12:26:40 EST 1990:
- Fix rare extra underscore in character length parameters passed
-for multiple entry points.
-
-Wed Dec 19 17:19:26 EST 1990:
- Allow generation of C despite error messages about bad alignment
-forced by equivalence.
- Allow variable-length concatenations in I/O statements, such as
- open(3, file=bletch(1:n) // '.xyz')
-
-Fri Dec 28 17:08:30 EST 1990:
- Fix bug under -p with formats and internal I/O "units" in COMMON,
-as in
- COMMON /FIGLEA/F
- CHARACTER*20 F
- F = '(A)'
- WRITE (*,FMT=F) 'Hello, world!'
- END
-
-Tue Jan 15 12:00:24 EST 1991:
- Fix bug when two equivalence groups are merged, the second with
-nonzero offset, and the result is then merged into a common block.
-Example:
- INTEGER W(3), X(3), Y(3), Z(3)
- COMMON /ZOT/ Z
- EQUIVALENCE (W(1),X(1)), (X(2),Y(1)), (Z(3),X(1))
-***** W WAS GIVEN THE WRONG OFFSET
- Recognize Fortran 90's optional NML= in NAMELIST READs and WRITEs.
-(Currently NML= and FMT= are treated as synonyms -- there's no
-error message if, e.g., NML= specifies a format.)
- libi77: minor adjustment to allow internal READs from character
-string constants in read-only memory.
-
-Fri Jan 18 22:56:15 EST 1991:
- Add comment to README about needing to comment out the typedef of
-size_t in sysdep.h on some systems, e.g. Sun 4.1.
- Fix misspelling of "statement" in an error message in lex.c
-
-Wed Jan 23 00:38:48 EST 1991:
- Allow hex, octal, and binary constants to have the qualifying letter
-(z, x, o, or b) either before or after the quoted string containing the
-digits. For now this change will not be reflected in f2c.ps .
-
-Tue Jan 29 16:23:45 EST 1991:
- Arrange for character-valued statement functions to give results of
-the right length (that of the statement function's name).
-
-Wed Jan 30 07:05:32 EST 1991:
- More tweaks for character-valued statement functions: an error
-check and an adjustment so a right-hand side of nonconstant length
-(e.g., a substring) is handled right.
-
-Wed Jan 30 09:49:36 EST 1991:
- Fix p1_head to avoid printing (char *)0 with %s.
-
-Thu Jan 31 13:53:44 EST 1991:
- Add a test after the cleanup call generated for I/O statements with
-ERR= or END= clauses to catch the unlikely event that the cleanup
-routine encounters an error.
-
-Mon Feb 4 08:00:58 EST 1991:
- Minor cleanup: omit unneeded jumps and labels from code generated for
-some NAMELIST READs and WRITEs with IOSTAT=, ERR=, and/or END=.
-
-Tue Feb 5 01:39:36 EST 1991:
- Change Mktemp to mktmp (for the benefit of systems so brain-damaged
-that they do not distinguish case in external names -- and that for
-some reason want to load mktemp). Try to get xsum0.out right this
-time (it somehow didn't get updated on 4 Feb. 1991).
- Add note to libi77/README about adjusting the interpretation of
-RECL= specifiers in OPENs for direct unformatted I/O.
-
-Thu Feb 7 17:24:42 EST 1991:
- New option -r casts values of REAL functions, including intrinsics,
-to REAL. This only matters for unportable code like
- real r
- r = asin(1.)
- if (r .eq. asin(1.)) ...
-[The behavior of such code varies with the Fortran compiler used --
-and sometimes is affected by compiler options.] For now, the man page
-at the end of f2c.ps is the only part of f2c.ps that reflects this new
-option.
-
-Fri Feb 8 18:12:51 EST 1991:
- Cast pointer differences passed as arguments to the appropriate type.
-This matters, e.g., with MSDOS compilers that yield a long pointer
-difference but have int == short.
- Disallow nonpositive dimensions.
-
-Fri Feb 15 12:24:15 EST 1991:
- Change %d to %ld in sprintf call in putpower in putpcc.c.
- Free more memory (e.g. allowing translation of larger Fortran
-files under MS-DOS).
- Recognize READ (character expression) and WRITE (character expression)
-as formatted I/O with the format given by the character expression.
- Update year in Notice.
-
-Sat Feb 16 00:42:32 EST 1991:
- Recant recognizing WRITE(character expression) as formatted output
--- Fortran 77 is not symmetric in its syntax for READ and WRITE.
-
-Mon Mar 4 15:19:42 EST 1991:
- Fix bug in passing the real part of a complex argument to an intrinsic
-function. Omit unneeded parentheses in nested calls to intrinsics.
-Example:
- subroutine foo(x, y)
- complex y
- x = exp(sin(real(y))) + exp(imag(y))
- end
-
-Fri Mar 8 15:05:42 EST 1991:
- Fix a comment in expr.c; omit safstrncpy.c (which had bugs in
-cases not used by f2c).
-
-Wed Mar 13 02:27:23 EST 1991:
- Initialize firstmemblock->next in mem_init in mem.c . [On most
-systems it was fortuituously 0, but with System V, -lmalloc could
-trip on this missed initialization.]
-
-Wed Mar 13 11:47:42 EST 1991:
- Fix a reference to freed memory.
-
-Wed Mar 27 00:42:19 EST 1991:
- Fix a memory fault caused by such illegal Fortran as
- function foo
- x = 3
- logical foo ! declaration among executables
- foo=.false. ! used to suffer memory fault
- end
-
-Fri Apr 5 08:30:31 EST 1991:
- Fix loss of % in some format expressions, e.g.
- write(*,'(1h%)')
- Fix botch introduced 27 March 1991 that caused subroutines with
-multiple entry points to have extraneous declarations of ret_val.
-
-Fri Apr 5 12:44:02 EST 1991
- Try again to omit extraneous ret_val declarations -- this morning's
-fix was sometimes wrong.
-
-Mon Apr 8 13:47:06 EDT 1991:
- Arrange for s_rnge to have the right prototype under -A -C .
-
-Wed Apr 17 13:36:03 EDT 1991:
- New fatal error message for apparent invocation of a recursive
-statement function.
-
-Thu Apr 25 15:13:37 EDT 1991:
- F2c and libi77 adjusted so NAMELIST works with -i2. (I forgot
-about -i2 when adding NAMELIST.) This required a change to f2c.h
-(that only affects NAMELIST I/O under -i2.) Man-page description of
--i2 adjusted to reflect that -i2 stores array lengths in short ints.
-
-Fri Apr 26 02:54:41 EDT 1991:
- Libi77: fix some bugs in NAMELIST reading of multi-dimensional arrays
-(file rsne.c).
-
-Thu May 9 02:13:51 EDT 1991:
- Omit a trailing space in expr.c (could cause a false xsum value if
-a mailer drops the trailing blank).
-
-Thu May 16 13:14:59 EDT 1991:
- Libi77: increase LEFBL in lio.h to overcome a NeXT bug.
- Tweak for compilers that recognize "nested" comments: inside comments,
-turn /* into /+ (as well as */ into +/).
-
-Sat May 25 11:44:25 EDT 1991:
- libf77: s_rnge: declare line long int rather than int.
-
-Fri May 31 07:51:50 EDT 1991:
- libf77: system_: officially return status.
-
-Mon Jun 17 16:52:53 EDT 1991:
- Minor tweaks: omit unnecessary declaration of strcmp (that caused
-trouble on a system where strcmp was a macro) from misc.c; add
-SHELL = /bin/sh to makefiles.
- Fix a dereference of null when a CHARACTER*(*) declaration appears
-(illegally) after DATA. Complain only once per subroutine about
-declarations appearing after DATA.
-
-Mon Jul 1 00:28:13 EDT 1991:
- Add test and error message for illegal use of subroutine names, e.g.
- SUBROUTINE ZAP(A)
- ZAP = A
- END
-
-Mon Jul 8 21:49:20 EDT 1991:
- Issue a warning about things like
- integer i
- i = 'abc'
-(which is treated as i = ichar('a')). [It might be nice to treat 'abc'
-as an integer initialized (in a DATA statement) with 'abc', but
-other matters have higher priority.]
- Render
- i = ichar('A')
-as
- i = 'A';
-rather than
- i = 65;
-(which assumes ASCII).
-
-Fri Jul 12 07:41:30 EDT 1991:
- Note added to README about erroneous definitions of __STDC__ .
-
-Sat Jul 13 13:38:54 EDT 1991:
- Fix bugs in double type convesions of complex values, e.g.
-sngl(real(...)) or dble(real(...)) (where ... is complex).
-
-Mon Jul 15 13:21:42 EDT 1991:
- Fix bug introduced 8 July 1991 that caused erroneous warnings
-"ichar([first char. of] char. string) assumed for conversion to numeric"
-when a subroutine had an array of character strings as an argument.
-
-Wed Aug 28 01:12:17 EDT 1991:
- Omit an unused function in format.c, an unused variable in proc.c .
- Under -r8, promote complex to double complex (as the man page claims).
-
-Fri Aug 30 17:19:17 EDT 1991:
- f2c.ps updated: slightly expand description of intrinsics and,or,xor,
-not; add mention of intrinsics lshift, rshift; add note about f2c
-accepting Fortran 90 inline comments (starting with !); update Cobalt
-Blue address.
-
-Tue Sep 17 07:17:33 EDT 1991:
- libI77: err.c and open.c modified to use modes "rb" and "wb"
-when (f)opening unformatted files; README updated to point out
-that it may be necessary to change these modes to "r" and "w"
-on some non-ANSI systems.
-
-Tue Oct 15 10:25:49 EDT 1991:
- Minor tweaks that make some PC compilers happier: insert some
-casts, add args to signal functions.
- Change -g to emit uncommented #line lines -- and to emit more of them;
-update fc, f2c.1, f2c.1t, f2c.ps to reflect this.
- Change uchar to Uchar in xsum.c .
- Bring gram.c up to date.
-
-Thu Oct 17 09:22:05 EDT 1991:
- libi77: README, fio.h, sue.c, uio.c changed so the length field
-in unformatted sequential records has type long rather than int
-(unless UIOLEN_int is #defined). This is for systems where sizeof(int)
-can vary, depending on the compiler or compiler options.
-
-Thu Oct 17 13:42:59 EDT 1991:
- libi77: inquire.c: when MSDOS is defined, don't strcmp units[i].ufnm
-when it is NULL.
-
-Fri Oct 18 15:16:00 EDT 1991:
- Correct xsum0.out in "all from f2c/src" (somehow botched on 15 Oct.).
-
-Tue Oct 22 18:12:56 EDT 1991:
- Fix memory fault when a character*(*) argument is used (illegally)
-as a dummy variable in the definition of a statement function. (The
-memory fault occurred when the statement function was invoked.)
- Complain about implicit character*(*).
-
-Thu Nov 14 08:50:42 EST 1991:
- libi77: change uint to Uint in fmt.h, rdfmt.c, wrtfmt.c; this change
-should be invisible unless you're running a brain-damaged system.
-
-Mon Nov 25 19:04:40 EST 1991:
- libi77: correct botches introduced 17 Oct. 1991 and 14 Nov. 1991
-(change uint to Uint in lwrite.c; other changes that only matter if
-sizeof(int) != sizeof(long)).
- Add a more meaningful error message when bailing out due to an attempt
-to invoke a COMMON variable as a function.
-
-Sun Dec 1 19:29:24 EST 1991:
- libi77: uio.c: add test for read failure (seq. unformatted reads);
-adjust an error return from EOF to off end of record.
-
-Tue Dec 10 17:42:28 EST 1991:
- Add tests to prevent memory faults with bad uses of character*(*).
-
-Thu Dec 12 11:24:41 EST 1991:
- libi77: fix bug with internal list input that caused the last
-character of each record to be ignored; adjust error message in
-internal formatted input from "end-of-file" to "off end of record"
-if the format specifies more characters than the record contains.
-
-Wed Dec 18 17:48:11 EST 1991:
- Fix bug in translating nonsensical ichar invocations involving
-concatenations.
- Fix bug in passing intrinsics lle, llt, lge, lgt as arguments;
-hl_le was being passed rather than l_le, etc.
- libf77: adjust length parameters from long to ftnlen, for
-compiling with f2c_i2 defined.
-
-Sat Dec 21 15:30:57 EST 1991:
- Allow DO nnn ... to end with an END DO statement labelled nnn.
-
-Tue Dec 31 13:53:47 EST 1991:
- Fix bug in handling dimension a(n**3,2) -- pow_ii was called
-incorrectly.
- Fix bug in translating
- subroutine x(abc,n)
- character abc(n)
- write(abc,'(i10)') 123
- end
-(omitted declaration and initialiation of abc_dim1).
- Complain about dimension expressions of such invalid types
-as complex and logical.
-
-Fri Jan 17 11:54:20 EST 1992:
- Diagnose some illegal uses of main program name (rather than
-memory faulting).
- libi77: (1) In list and namelist input, treat "r* ," and "r*,"
-alike (where r is a positive integer constant), and fix a bug in
-handling null values following items with repeat counts (e.g.,
-2*1,,3). (2) For namelist reading of a numeric array, allow a new
-name-value subsequence to terminate the current one (as though the
-current one ended with the right number of null values).
-(3) [lio.h, lwrite.c]: omit insignificant zeros in list and namelist
-output. (Compile with -DOld_list_output to get the old behavior.)
-
-Sat Jan 18 15:58:01 EST 1992:
- libi77: make list output consistent with F format by printing .1
-rather than 0.1 (introduced yesterday).
-
-Wed Jan 22 08:32:43 EST 1992:
- libi77: add comment to README pointing out preconnection of
-Fortran units 5, 6, 0 to stdin, stdout, stderr (respectively).
-
-Mon Feb 3 11:57:53 EST 1992:
- libi77: fix namelist read bug that caused the character following
-a comma to be ignored.
-
-Fri Feb 28 01:04:26 EST 1992:
- libf77: fix buggy z_sqrt.c (double precision square root), which
-misbehaved for arguments in the southwest quadrant.
-
-Thu Mar 19 15:05:18 EST 1992:
- Fix bug (introduced 17 Jan 1992) in handling multiple entry points
-of differing types (with implicitly typed entries appearing after
-the first executable statement).
- Fix memory fault in the following illegal Fortran:
- double precision foo(i)
-* illegal: above should be "double precision function foo(i)"
- foo = i * 3.2
- entry moo(i)
- end
- Note about ANSI_Libraries (relevant, e.g., to IRIX 4.0.1 and AIX)
-added to README.
- Abort zero divides during constant simplification.
-
-Sat Mar 21 01:27:09 EST 1992:
- Tweak ckalloc (misc.c) for systems where malloc(0) = 0; this matters
-for subroutines with multiple entry points but no arguments.
- Add "struct memblock;" to init.c (irrelevant to most compilers).
-
-Wed Mar 25 13:31:05 EST 1992:
- Fix bug with IMPLICIT INTEGER*4(...): under -i2 or -I2, the *4 was
-ignored.
-
-Tue May 5 09:53:55 EDT 1992:
- Tweaks to README; e.g., ANSI_LIbraries changed to ANSI_Libraries .
-
-Wed May 6 23:49:07 EDT 1992
- Under -A and -C++, have subroutines return 0 (even if they have
-no * arguments).
- Adjust libi77 (rsne.c and lread.c) for systems where ungetc is
-a macro. Tweak lib[FI]77/makefile to use unique intermediate file
-names (for parallel makes).
-
-Tue May 19 09:03:05 EDT 1992:
- Adjust libI77 to make err= work with internal list and formatted I/O.
-
-Sat May 23 18:17:42 EDT 1992:
- Under -A and -C++, supply "return 0;" after the code generated for
-a STOP statement -- the C compiler doesn't know that s_stop won't
-return.
- New (mutually exclusive) options:
- -f treats all input lines as free-format lines,
- honoring text that appears after column 72
- and not padding lines shorter than 72 characters
- with blanks (which matters if a character string
- is continued across 2 or more lines).
- -72 treats text appearing after column 72 as an error.
-
-Sun May 24 09:45:37 EDT 1992:
- Tweak description of -f in f2c.1 and f2c.1t; update f2c.ps .
-
-Fri May 29 01:17:15 EDT 1992:
- Complain about externals used as variables. Example
- subroutine foo(a,b)
- external b
- a = a*b ! illegal use of b; perhaps should be b()
- end
-
-Mon Jun 15 11:15:27 EDT 1992:
- Fix bug in handling namelists with names that have underscores.
-
-Sat Jun 27 17:30:59 EDT 1992:
- Under -A and -C++, end Main program aliases with "return 0;".
- Under -A and -C++, use .P files and usage in previous subprograms
-in the current file to give prototypes for functions declared EXTERNAL
-but not invoked.
- Fix memory fault under -d1 -P .
- Under -A and -C++, cast arguments to the right types in calling
-a function that has been defined in the current file or in a .P file.
- Fix bug in handling multi-dimensional arrays with array references
-in their leading dimensions.
- Fix bug in the intrinsic cmplx function when the first argument
-involves an expression for which f2c generates temporary variables,
-e.g. cmplx(abs(real(a)),1.) .
-
-Sat Jul 18 07:36:58 EDT 1992:
- Fix buglet with -e1c (invisible on most systems) temporary file
-f2c_functions was unlinked before being closed.
- libf77: fix bugs in evaluating m**n for integer n < 0 and m an
-integer different from 1 or a real or double precision 0.
-Catch SIGTRAP (to print "Trace trap" before aborting). Programs
-that previously erroneously computed 1 for 0**-1 may now fault.
-Relevant routines: main.c pow_di.c pow_hh.c pow_ii.c pow_ri.c .
-
-Sat Jul 18 08:40:10 EDT 1992:
- libi77: allow namelist input to end with & (e.g. &end).
-
-Thu Jul 23 00:14:43 EDT 1992
- Append two underscores rather than one to C keywords used as
-local variables to avoid conflicts with similarly named COMMON blocks.
-
-Thu Jul 23 11:20:55 EDT 1992:
- libf77, libi77 updated to assume ANSI prototypes unless KR_headers
-is #defined.
- libi77 now recognizes a Z format item as in Fortran 90;
-the implementation assumes 8-bit bytes and botches character strings
-on little-endian machines (by printing their bytes from right to
-left): expect this bug to persist; fixing it would require a
-change to the I/O calling sequences.
-
-Tue Jul 28 15:18:33 EDT 1992:
- libi77: insert missed "#ifdef KR_headers" lines around getnum
-header in rsne.c. Version not updated.
-
-NOTE: "index from f2c" now ends with current timestamps of files in
-"all from f2c/src", sorted by time. To bring your source up to date,
-obtain source files with a timestamp later than the time shown in your
-version.c.
-
-Fri Aug 14 08:07:09 EDT 1992:
- libi77: tweak wrt_E in wref.c to avoid signing NaNs.
-
-Sun Aug 23 19:05:22 EDT 1992:
- fc: supply : after O in getopt invocation (for -O1 -O2 -O3).
-
-Mon Aug 24 18:37:59 EDT 1992:
- Recant above tweak to fc: getopt is dumber than I thought;
-it's necessary to say -O 1 (etc.).
- libF77/README: add comments about ABORT, ERF, DERF, ERFC, DERFC,
-GETARG, GETENV, IARGC, SIGNAL, and SYSTEM.
-
-Tue Oct 27 01:57:42 EST 1992:
- libf77, libi77:
- 1. Fix botched indirection in signal_.c.
- 2. Supply missing l_eof = 0 assignment to s_rsne() in rsne.c (so
-end-of-file on other files won't confuse namelist reads of external
-files).
- 3. Prepend f__ to external names that are only of internal
-interest to lib[FI]77.
-
-Thu Oct 29 12:37:18 EST 1992:
- libf77: Fix botch in signal_.c when KR_headers is #defined;
-add CFLAGS to makefile.
- libi77: trivial change to makefile for consistency with
-libF77/makefile.
-
-Wed Feb 3 02:05:16 EST 1993:
- Recognize types INTEGER*1, LOGICAL*1, LOGICAL*2, INTEGER*8.
-INTEGER*8 is not well tested and will only work reasonably on
-systems where int = 4 bytes, long = 8 bytes; on such systems,
-you'll have to modify f2c.h appropriately, changing integer
-from long to int and adding typedef long longint. You'll also
-have to compile libI77 with Allow_TYQUAD #defined and adjust
-libF77/makefile to compile pow_qq.c. In the f2c source, changes
-for INTEGER*8 are delimited by #ifdef TYQUAD ... #endif. You
-can omit the INTEGER*8 changes by compiling with NO_TYQUAD
-#defined. Otherwise, the new command-line option -!i8
-disables recognition of INTEGER*8.
- libf77: add pow_qq.c
- libi77: add #ifdef Allow_TYQUAD stuff. Changes for INTEGER*1,
-LOGICAL*1, and LOGICAL*2 came last 23 July 1992. Fix bug in
-backspace (that only bit when the last character of the second
-or subsequent buffer read was the previous newline). Guard
-against L_tmpnam being too small in endfile.c. For MSDOS,
-close and reopen files when copying to truncate. Lengthen
-LINTW (buffer size in lwrite.c).
- Add \ to the end of #define lines that get broken.
- Fix bug in handling NAMELIST of items in EQUIVALENCE.
- Under -h (or -hd), convert Hollerith to integer in general expressions
-(e.g., assignments), not just when they're passed as arguments, and
-blank-pad rather than 0-pad the Hollerith to a multiple of
-sizeof(integer) or sizeof(doublereal).
- Add command-line option -s, which instructs f2c preserve multi-
-dimensional subscripts (by emitting and using appropriate #defines).
- Fix glitch (with default type inferences) in examples like
- call foo('abc')
- end
- subroutine foo(goo)
- end
-This gave two warning messages:
- Warning on line 4 of y.f: inconsistent calling sequences for foo:
- here 1, previously 2 args and string lengths.
- Warning on line 4 of y.f: inconsistent calling sequences for foo:
- here 2, previously 1 args and string lengths.
-Now the second Warning is suppressed.
- Complain about all inconsistent arguments, not just the first.
- Switch to automatic creation of "all from f2c/src". For folks
-getting f2c source via ftp, this means f2c/src/all.Z is now an
-empty file rather than a bundle.
- Separate -P and -A: -P no longer implies -A.
-
-Thu Feb 4 00:32:20 EST 1993:
- Fix some glitches (introduced yesterday) with -h .
-
-Fri Feb 5 01:40:38 EST 1993:
- Fix bug in types conveyed for namelists (introduced 3 Feb. 1993).
-
-Fri Feb 5 21:26:43 EST 1993:
- libi77: tweaks to NAMELIST and open (after comments by Harold
-Youngren):
- 1. Reading a ? instead of &name (the start of a namelist) causes
- the namelist being sought to be written to stdout (unit 6);
- to omit this feature, compile rsne.c with -DNo_Namelist_Questions.
- 2. Reading the wrong namelist name now leads to an error message
- and an attempt to skip input until the right namelist name is found;
- to omit this feature, compile rsne.c with -DNo_Bad_Namelist_Skip.
- 3. Namelist writes now insert newlines before each variable; to omit
- this feature, compile xwsne.c with -DNo_Extra_Namelist_Newlines.
- 4. For OPEN of sequential files, ACCESS='APPEND' (or
- access='anything else starting with "A" or "a"') causes the file to
- be positioned at end-of-file, so a write will append to the file.
- (This is nonstandard, but does not require modifying data
- structures.)
-
-Mon Feb 8 14:40:37 EST 1993:
- Increase number of continuation lines allowed from 19 to 99,
-and allow changing this limit with -NC (e.g. -NC200 for 200 lines).
- Treat control-Z (at the beginning of a line) as end-of-file: see
-the new penultimate paragraph of README.
- Fix a rarely seen glitch that could make an error messages to say
-"line 0".
-
-Tue Feb 9 02:05:40 EST 1993
- libi77: change some #ifdef MSDOS lines to #ifdef NON_UNIX_STDIO,
-and, in err.c under NON_UNIX_STDIO, avoid close(creat(name,0666))
-when the unit has another file descriptor for name.
-
-Tue Feb 9 17:12:49 EST 1993
- libi77: more tweaks for NON_UNIX_STDIO: use stdio routines
-rather than open, close, creat, seek, fdopen (except for f__isdev).
-
-Fri Feb 12 15:49:33 EST 1993
- Update src/gram.c (which was forgotten in the recent updates).
-Most folks regenerate it anyway (wity yacc or bison).
-
-Thu Mar 4 17:07:38 EST 1993
- Increase default max labels in computed gotos and alternate returns
-to 257, and allow -Nl1234 to specify this number.
- Tweak put.c to check p->tag == TADDR in realpart() and imagpart().
- Adjust fc script to allow .r (RATFOR) files and -C (check subscripts).
- Avoid declaring strchr in niceprintf.c under -DANSI_Libraries .
- gram.c updated again.
- libi77: err.c, open.c: take declaration of fdopen from rawio.h.
-
-Sat Mar 6 07:09:11 EST 1993
- libi77: uio.c: adjust off-end-of-record test for sequential
-unformatted reads to respond to err= rather than end= .
-
-Sat Mar 6 16:12:47 EST 1993
- Treat scalar arguments of the form (v) and v+0, where v is a variable,
-as expressions: assign to a temporary variable, and pass the latter.
- gram.c updated.
-
-Mon Mar 8 09:35:38 EST 1993
- "f2c.h from f2c" updated to add types logical1 and integer1 for
-LOGICAL*1 and INTEGER*1. ("f2c.h from f2c" is supposed to be the
-same as "f2c.h from f2c/src", which was updated 3 Feb. 1993.)
-
-Mon Mar 8 17:57:55 EST 1993
- Fix rarely seen bug that could cause strange casts in function
-invocations (revealed by an example with msdos/f2c.exe).
- msdos/f2cx.exe.Z and msdos/f2c.exe.Z updated (ftp access only).
-
-Fri Mar 12 12:37:01 EST 1993
- Fix bug with -s in handling subscripts involving min, max, and
-complicated expressions requiring temporaries.
- Fix bug in handling COMMONs that need padding by a char array.
- msdos/f2cx.exe.Z and msdos/f2c.exe.Z updated (ftp access only).
-
-Fri Mar 12 17:16:16 EST 1993
- libf77, libi77: updated for compiling under C++.
-
-Mon Mar 15 16:21:37 EST 1993
- libi77: more minor tweaks (for -DKR_headers); Version.c not changed.
-
-Thu Mar 18 12:37:30 EST 1993
- Flag -r (for discarding carriage-returns on systems that end lines
-with carriage-return/newline pairs, e.g. PCs) added to xsum, and
-xsum.c converted to ANSI/ISO syntax (with K&R syntax available with
--DKR_headers). [When time permits, the f2c source will undergo a
-similar conversion.]
- libi77: tweaks to #includes in endfile.c, err.c, open.c, rawio.h;
-Version.c not changed.
- f2c.ps updated (to pick up revision of 2 Feb. 1993 to f2c.1).
-
-Fri Mar 19 09:19:26 EST 1993
- libi77: add (char *) casts to malloc and realloc invocations
-in err.c, open.c; Version.c not changed.
-
-Tue Mar 30 07:17:15 EST 1993
- Fix bug introduced 6 March 1993: possible memory corruption when
-loops in data statements involve constant subscripts, as in
- DATA (GUNIT(1,I),I=0,14)/15*-1/
-
-Tue Mar 30 16:17:42 EST 1993
- Fix bug with -s: (floating-point array item)*(complex item)
-generates an _subscr() reference for the floating-point array,
-but a #define for the _subscr() was omitted.
-
-Tue Apr 6 12:11:22 EDT 1993
- libi77: adjust error returns for formatted inputs to flush the current
-input line when err= is specified. To restore the old behavior (input
-left mid-line), either adjust the #definition of errfl in fio.h or omit
-the invocation of f__doend in err__fl (in err.c).
-
-Tue Apr 6 13:30:04 EDT 1993
- Fix bug revealed in
- subroutine foo(i)
- call goo(int(i))
- end
-which now passes a copy of i, rather than i itself.
-
-Sat Apr 17 11:41:02 EDT 1993
- Adjust appending of underscores to conform with f2c.ps ("A Fortran
-to C Converter"): names that conflict with C keywords or f2c type
-names now have just one underscore appended (rather than two); add
-"integer1", "logical1", "longint" to the keyword list.
- Append underscores to names that appear in EQUIVALENCE and are
-component names in a structure declared in f2c.h, thus avoiding a
-problem caused by the #defines emitted for equivalences. Example:
- complex a
- equivalence (i,j)
- a = 1 ! a.i went awry because of #define i
- j = 2
- write(*,*) a, i
- end
- Adjust line-breaking logic to avoid splitting very long constants
-(and names). Example:
- ! The next line starts with tab and thus is a free-format line.
- a=.012345689012345689012345689012345689012345689012345689012345689012345689
- end
- Omit extraneous "return 0;" from entry stubs emitted for multiple
-entry points of type character, complex, or double complex.
-
-Sat Apr 17 14:35:05 EDT 1993
- Fix bug (introduced 4 Feb.) in separating -P from -A that kept f2c
-from re-reading a .P file written without -A or -C++ describing a
-routine with an external argument. [See the just-added note about
-separating -P from -A in the changes above for 3 Feb. 1993.]
- Fix bug (type UNKNOWN for V in the example below) revealed by
- subroutine a()
- external c
- call b(c)
- end
- subroutine b(v)
- end
-
-Sun Apr 18 19:55:26 EDT 1993
- Fix wrong calling sequence for mem() in yesterday's addition to
-equiv.c .
-
-Wed Apr 21 17:39:46 EDT 1993
- Fix bug revealed in
-
- ASSIGN 10 TO L1
- GO TO 20
- 10 ASSIGN 30 TO L2
- STOP 10
-
- 20 ASSIGN 10 TO L2 ! Bug here because 10 had been assigned
- ! to another label, then defined.
- GO TO L2
- 30 END
-
-Fri Apr 23 18:38:50 EDT 1993
- Fix bug with -h revealed in
- CHARACTER*9 FOO
- WRITE(FOO,'(I6)') 1
- WRITE(FOO,'(I6)') 2 ! struct icilist io___3 botched
- END
-
-Tue Apr 27 16:08:28 EDT 1993
- Tweak to makefile: remove "size f2c".
-
-Tue May 4 23:48:20 EDT 1993
- libf77: tweak signal_ line of f2ch.add .
-
-Tue Jun 1 13:47:13 EDT 1993
- Fix bug introduced 3 Feb. 1993 in handling multiple entry
-points with differing return types -- the postfix array in proc.c
-needed a new entry for integer*8 (which resulted in wrong
-Multitype suffixes for non-integral types).
- For (default) K&R C, generate VOID rather than int functions for
-functions of Fortran type character, complex, and double complex.
- msdos/f2cx.exe.Z and msdos/f2c.exe.Z updated (ftp access only).
-
-Tue Jun 1 23:11:15 EDT 1993
- f2c.h: add Multitype component g and commented type longint.
- proc.c: omit "return 0;" from stubs for complex and double complex
-entries (when entries have multiple types); add test to avoid memory
-fault with illegal combinations of entry types.
-
-Mon Jun 7 12:00:47 EDT 1993
- Fix memory fault in
- common /c/ m
- integer m(1)
- data m(1)/1/, m(2)/2/ ! one too many initializers
- end
- msdos/f2cx.exe.Z and msdos/f2c.exe.Z updated (ftp access only).
-
-Fri Jun 18 13:55:51 EDT 1993
- libi77: change type of signal_ in f2ch.add; change type of il in
-union Uint from long to integer (for machines like the DEC Alpha,
-where integer should be the same as int). Version.c not changed.
- Tweak gram.dcl and gram.head: add semicolons after some rules that
-lacked them, and remove an extraneous semicolon. These changes are
-completely transparent to our local yacc programs, but apparently
-matter on some VMS systems.
-
-Wed Jun 23 01:02:56 EDT 1993
- Update "fc" shell script, and bring f2c.1 and f2c.1t up to date:
-they're meant to be linked with (i.e., the same as) src/f2c.1 and
-src/f2c.1t . [In the last update of f2c.1* (2 Feb. 1993), only
-src/f2c.1 and src/f2c.1t got changed -- a mistake.]
-
-Wed Jun 23 09:04:31 EDT 1993
- libi77: fix bug in format reversions for internal writes.
-Example:
- character*60 lines(2)
- write(lines,"('n =',i3,2(' more text',i3))") 3, 4, 5, 6
- write(*,*) 'lines(1) = ', lines(1)
- write(*,*) 'lines(2) = ', lines(2)
- end
-gave an error message that began "iio: off end of record", rather
-than giving the correct output:
-
- lines(1) = n = 3 more text 4 more text 5
- lines(2) = more text 6 more text
-
-Thu Aug 5 11:31:14 EDT 1993
- libi77: lread.c: fix bug in handling repetition counts for logical
-data (during list or namelist input). Change struct f__syl to
-struct syl (for buggy compilers).
-
-Sat Aug 7 16:05:30 EDT 1993
- libi77: lread.c (again): fix bug in namelist reading of incomplete
-logical arrays.
- Fix minor calling-sequence errors in format.c, output.c, putpcc.c:
-should be invisible.
-
-Mon Aug 9 09:12:38 EDT 1993
- Fix erroneous cast under -A in translating
- character*(*) function getc()
- getc(2:3)=' ' !wrong cast in first arg to s_copy
- end
- libi77: lread.c: fix bug in namelist reading of an incomplete array
-of numeric data followed by another namelist item whose name starts
-with 'd', 'D', 'e', or 'E'.
-
-Fri Aug 20 13:22:10 EDT 1993
- Fix bug in do while revealed by
- subroutine skdig (line, i)
- character line*(*), ch*1
- integer i
- logical isdigit
- isdigit(ch) = ch.ge.'0' .and. ch.le.'9'
- do while (isdigit(line(i:i))) ! ch__1[0] was set before
- ! "while(...) {...}"
- i = i + 1
- enddo
- end
-
-Fri Aug 27 08:22:54 EDT 1993
- Add #ifdefs to avoid declaring atol when it is a macro; version.c
-not updated.
-
-Wed Sep 8 12:24:26 EDT 1993
- libi77: open.c: protect #include "sys/..." with
-#ifndef NON_UNIX_STDIO; Version date not changed.
-
-Thu Sep 9 08:51:21 EDT 1993
- Adjust "include" to interpret file names relative to the directory
-of the file that contains the "include".
-
-Fri Sep 24 00:56:12 EDT 1993
- Fix offset error resulting from repeating the same equivalence
-statement twice. Example:
- real a(2), b(2)
- equivalence (a(2), b(2))
- equivalence (a(2), b(2))
- end
- Increase MAXTOKENLEN (to roughly the largest allowed by ANSI C).
-
-Mon Sep 27 08:55:09 EDT 1993
- libi77: endfile.c: protect #include "sys/types.h" with
-#ifndef NON_UNIX_STDIO; Version.c not changed.
-
-Fri Oct 15 15:37:26 EDT 1993
- Fix rarely seen parsing bug illustrated by
- subroutine foo(xabcdefghij)
- character*(*) xabcdefghij
- IF (xabcdefghij.NE.'##') GOTO 40
- 40 end
-in which the spacing in the IF line is crucial.
-
-Thu Oct 21 13:55:11 EDT 1993
- Give more meaningful error message (then "unexpected character in
-cds") when constant simplification leads to Infinity or NaN.
-
-Wed Nov 10 15:01:05 EST 1993
- libi77: backspace.c: adjust, under -DMSDOS, to cope with MSDOS
-text files, as handled by some popular PC C compilers. Beware:
-the (defective) libraries associated with these compilers assume lines
-end with \r\n (conventional MS-DOS text files) -- and ftell (and
-hence the current implementation of backspace) screws up if lines with
-just \n.
-
-Thu Nov 18 09:37:47 EST 1993
- Give a better error (than "control stack empty") for an extraneous
-ENDDO. Example:
- enddo
- end
- Update comments about ftp in "readme from f2c".
-
-Sun Nov 28 17:26:50 EST 1993
- Change format of time stamp in version.c to yyyymmdd.
- Sort parameter adjustments (or complain of impossible dependencies)
-so that dummy arguments are referenced only after being adjusted.
-Example:
- subroutine foo(a,b)
- integer a(2) ! a must be adjusted before b
- double precision b(a(1),a(2))
- call goo(b(3,4))
- end
- Adjust structs for initialized common blocks and equivalence classes
-to omit the trailing struct component added to force alignment when
-padding already forces the desired alignment. Example:
- PROGRAM TEST
- COMMON /Z/ A, CC
- CHARACTER*4 CC
- DATA cc /'a'/
- END
-now gives
- struct {
- integer fill_1[1];
- char e_2[4];
- } z_ = { {0}, {'a', ' ', ' ', ' '} };
-rather than
-struct {
- integer fill_1[1];
- char e_2[4];
- real e_3;
- } z_ = { {0}, {'a', ' ', ' ', ' '}, (float)0. };
-
-Wed Dec 8 16:24:43 EST 1993
- Adjust lex.c to recognize # nnn "filename" lines emitted by cpp;
-this affects the file names and line numbers in error messages and
-the #line lines emitted under -g.
- Under -g, arrange for a file that starts with an executable
-statement to have the first #line line indicate line 1, rather
-than the line number of the END statement ending the main program.
- Adjust fc script to run files ending in .F through /lib/cpp.
- Fix bug ("Impossible tag 2") in
- if (t .eq. (0,2)) write(*,*) 'Bug!'
- end
- libi77: iio.c: adjust internal formatted reads to treat short records
-as though padded with blanks (rather than causing an "off end of record"
-error).
-
-Wed Dec 15 15:19:15 EST 1993
- fc: adjusted for .F files to pass -D and -I options to cpp.
-
-Fri Dec 17 20:03:38 EST 1993
- Fix botch introduced 28 Nov. 1993 in vax.c; change "version of"
-to "version".
-
-Tue Jan 4 15:39:52 EST 1994
- msdos/f2cx.exe.Z and msdos/f2c.exe.Z updated (ftp access only).
-
-Wed Jan 19 08:55:19 EST 1994
- Arrange to accept
- integer Nx, Ny, Nz
- parameter (Nx = 10, Ny = 20)
- parameter (Nz = max(Nx, Ny))
- integer c(Nz)
- call foo(c)
- end
-rather than complaining "Declaration error for c: adjustable dimension
-on non-argument". The necessary changes cause some hitherto unfolded
-constant expressions to be folded.
- Accept BYTE as a synonym for INTEGER*1.
-
-Thu Jan 27 08:57:40 EST 1994
- Fix botch in changes of 19 Jan. 1994 that broke entry points with
-multi-dimensional array arguments that did not appear in the subprogram
-argument list and whose leading dimensions depend on arguments.
-
-Mon Feb 7 09:24:30 EST 1994
- Remove artifact in "fc" script that caused -O to be ignored:
- 87c87
- < # lcc ignores -O...
- ---
- > CFLAGS="$CFLAGS $O"
-
-Sun Feb 20 17:04:58 EST 1994
- Fix bugs reading .P files for routines with arguments of type
-INTEGER*1, INTEGER*8, LOGICAL*2.
- Fix glitch in reporting inconsistent arguments for routines involving
-character arguments: "arg n" had n too large by the number of
-character arguments.
-
-Tue Feb 22 20:50:08 EST 1994
- Trivial changes to data.c format.c main.c niceprintf.c output.h and
-sysdep.h (consistency improvements).
- libI77: lread.c: check for NULL return from realloc.
-
-Fri Feb 25 23:56:08 EST 1994
- output.c, sysdep.h: arrange for -DUSE_DTOA to use dtoa.c and g_fmt.c
-for correctly rounded decimal values on IEEE-arithmetic machines
-(plus machines with VAX and IBM-mainframe arithmetic). These
-routines are available from netlib's fp directory.
- msdos/f2cx.exe.Z and msdos/f2c.exe.Z updated (ftp access only); the
-former uses -DUSE_DTOA to keep 12 from printing as 12.000000000000001.
- vax.c: fix wrong arguments to badtag and frchain introduced
-28 Nov. 1993.
- Source for f2c converted to ANSI/ISO format, with the K&R format
-available by compilation with -DKR_headers .
- Arrange for (double precision expression) relop (single precision
-constant) to retain the single-precision nature of the constant.
-Example:
- double precision t
- if (t .eq. 0.3) ...
-
-Mon Feb 28 11:40:24 EST 1994
- README updated to reflect a modification just made to netlib's
-"dtoa.c from fp":
-96a97,105
-> Also add the rule
->
-> dtoa.o: dtoa.c
-> $(CC) -c $(CFLAGS) -DMALLOC=ckalloc -DIEEE... dtoa.c
->
-> (without the initial tab) to the makefile, where IEEE... is one of
-> IEEE_MC68k, IEEE_8087, VAX, or IBM, depending on your machine's
-> arithmetic. See the comments near the start of dtoa.c.

-
-Sat Mar 5 09:41:52 EST 1994
- Complain about functions with the name of a previously declared
-common block (which is illegal).
- New option -d specifies the directory for output .c and .P files;
-f2c.1 and f2c.1t updated. The former undocumented debug option -dnnn
-is now -Dnnn.
-
-Thu Mar 10 10:21:44 EST 1994
- libf77: add #undef min and #undef max lines to s_paus.c s_stop.c
-and system_.c; Version.c not changed.
- libi77: add -DPad_UDread lines to uio.c and explanation to README:
- Some buggy Fortran programs use unformatted direct I/O to write
- an incomplete record and later read more from that record than
- they have written. For records other than the last, the unwritten
- portion of the record reads as binary zeros. The last record is
- a special case: attempting to read more from it than was written
- gives end-of-file -- which may help one find a bug. Some other
- Fortran I/O libraries treat the last record no differently than
- others and thus give no help in finding the bug of reading more
- than was written. If you wish to have this behavior, compile
- uio.c with -DPad_UDread .
-Version.c not changed.
-
-Tue Mar 29 17:27:54 EST 1994
- Adjust make_param so dimensions involving min, max, and other
-complicated constant expressions do not provoke error messages
-about adjustable dimensions on non-arguments.
- Fix botch introduced 19 Jan 1994: "adjustable dimension on non-
-argument" messages could cause some things to be freed twice.
-
-Tue May 10 07:55:12 EDT 1994
- Trivial changes to exec.c, p1output.c, parse_args.c, proc.c,
-and putpcc.c: change arguments from
- type foo[]
-to
- type *foo
-for consistency with defs.h. For most compilers, this makes no
-difference.
-
-Thu Jun 2 12:18:18 EDT 1994
- Fix bug in handling FORMAT statements that have adjacent character
-(or Hollerith) strings: an extraneous \002 appeared between the
-strings.
- libf77: under -DNO_ONEXIT, arrange for f_exit to be called just
-once; previously, upon abnormal termination (including stop statements),
-it was called twice.
-
-Mon Jun 6 15:52:57 EDT 1994
- libf77: Avoid references to SIGABRT and SIGIOT if neither is defined;
-Version.c not changed.
- libi77: Add cast to definition of errfl() in fio.h; this only matters
-on systems with sizeof(int) < sizeof(long). Under -DNON_UNIX_STDIO,
-use binary mode for direct formatted files (to avoid any confusion
-connected with \n characters).
-
-Fri Jun 10 16:47:31 EDT 1994
- Fix bug under -A in handling unreferenced (and undeclared)
-external arguments in subroutines with multiple entry points. Example:
- subroutine m(fcn,futil)
- external fcn,futil
- call fcn
- entry mintio(i1) ! (D_fp)0 rather than (U_fp)0 for futil
- end
-
-Wed Jun 15 10:38:14 EDT 1994
- Allow char(constant expression) function in parameter declarations.
-(This was probably broken in the changes of 29 March 1994.)
-
-Fri Jul 1 23:54:00 EDT 1994
- Minor adjustments to makefile (rule for f2c.1 commented out) and
-sysdep.h (#undef KR_headers if __STDC__ is #defined, and base test
-for ANSI_Libraries and ANSI_Prototypes on KR_headers rather than
-__STDC__); version.c touched but not changed.
- libi77: adjust fp.h so local.h is only needed under -DV10;
-Version.c not changed.
-
-Tue Jul 5 03:05:46 EDT 1994
- Fix segmentation fault in
- subroutine foo(a,b,k)
- data i/1/
- double precision a(k,1) ! sequence error: must precede data
- b = a(i,1)
- end
- libi77: Fix bug (introduced 6 June 1994?) in reopening files under
-NON_UNIX_STDIO.
- Fix some error messages caused by illegal Fortran. Examples:
-* 1.
- x(i) = 0 !Missing declaration for array x
- call f(x) !Said Impossible storage class 8 in routine mkaddr
- end !Now says invalid use of statement function x
-* 2.
- f = g !No declaration for g; by default it's a real variable
- call g !Said invalid class code 2 for function g
- end !Now says g cannot be called
-* 3.
- intrinsic foo !Invalid intrinsic name
- a = foo(b) !Said intrcall: bad intrgroup 0
- end !Now just complains about line 1
-
-Tue Jul 5 11:14:26 EDT 1994
- Fix glitch in handling erroneous statement function declarations.
-Example:
- a(j(i) - i) = a(j(i) - i) + 1 ! bad statement function
- call foo(a(3)) ! Said Impossible type 0 in routine mktmpn
- end ! Now warns that i and j are not used
-
-Wed Jul 6 17:31:25 EDT 1994
- Tweak test for statement functions that (illegally) call themselves;
-f2c will now proceed to check for other errors, rather than bailing
-out at the first recursive statement function reference.
- Warn about but retain divisions by 0 (instead of calling them
-"compiler errors" and quiting). On IEEE machines, this permits
- double precision nan, ninf, pinf
- nan = 0.d0/0.d0
- pinf = 1.d0/0.d0
- ninf = -1.d0/0.d0
- write(*,*) 'nan, pinf, ninf = ', nan, pinf, ninf
- end
-to print
- nan, pinf, ninf = NaN Infinity -Infinity
- libi77: wref.c: protect with #ifdef GOOD_SPRINTF_EXPONENT an
-optimization that requires exponents to have 2 digits when 2 digits
-suffice. lwrite.c wsfe.c (list and formatted external output):
-omit ' ' carriage-control when compiled with -DOMIT_BLANK_CC .
-Off-by-one bug fixed in character count for list output of character
-strings. Omit '.' in list-directed printing of Nan, Infinity.
-
-Mon Jul 11 13:05:33 EDT 1994
- src/gram.c updated.
-
-Tue Jul 12 10:24:42 EDT 1994
- libi77: wrtfmt.c: under G11.4, write 0. as " .0000 " rather
-than " .0000E+00".
-
-Thu Jul 14 17:55:46 EDT 1994
- Fix glitch in changes of 6 July 1994 that could cause erroneous
-"division by zero" warnings (or worse). Example:
- subroutine foo(a,b)
- y = b
- a = a / y ! erroneous warning of division by zero
- end
-
-Mon Aug 1 16:45:17 EDT 1994
- libi77: lread.c rsne.c: for benefit of systems with a buggy stdio.h,
-declare ungetc when neither KR_headers nor ungetc is #defined.
-Version.c not changed.
-
-Wed Aug 3 01:53:00 EDT 1994
- libi77: lwrite.c (list output): do not insert a newline when
-appending an oversize item to an empty line.
-
-Mon Aug 8 00:51:01 EDT 1994
- Fix bug (introduced 3 Feb. 1993) that, under -i2, kept LOGICAL*2
-variables from appearing in INQUIRE statements. Under -I2, allow
-LOGICAL*4 variables to appear in INQUIRE. Fix intrinsic function
-LEN so it returns a short value under -i2, a long value otherwise.
- exec.c: fix obscure memory fault possible with bizarre (and highly
-erroneous) DO-loop syntax.
-
-Fri Aug 12 10:45:57 EDT 1994
- libi77: fix glitch that kept ERR= (in list- or format-directed input)
-from working after a NAMELIST READ.
-
-Thu Aug 25 13:58:26 EDT 1994
- Suppress -s when -C is specified.
- Give full pathname (netlib@research.att.com) for netlib in readme and
-src/README.
-
-Wed Sep 7 22:13:20 EDT 1994
- libi77: typesize.c: adjust to allow types LOGICAL*1, LOGICAL*2,
-INTEGER*1, and (under -DAllow_TYQUAD) INTEGER*8 in NAMELISTs.
-
-Fri Sep 16 17:50:18 EDT 1994
- Change name adjustment for reserved words: instead of just appending
-"_" (a single underscore), append "_a_" to local variable names to avoid
-trouble when a common block is named a reserved word and the same
-reserved word is also a local variable name. Example:
- common /const/ a,b,c
- real const(3)
- equivalence (const(1),a)
- a = 1.234
- end
- Arrange for ichar() to treat characters as unsigned.
- libf77: s_cmp.c: treat characters as unsigned in comparisons.
-These changes for unsignedness only matter for strings that contain
-non-ASCII characters. Now ichar() should always be >= 0.
-
-Sat Sep 17 11:19:32 EDT 1994
- fc: set rc=$? before exit (to get exit code right in trap code).
-
-Mon Sep 19 17:49:43 EDT 1994
- libf77: s_paus.c: flush stderr after PAUSE; add #ifdef MSDOS stuff.
- libi77: README: point out general need for -DMSDOS under MS-DOS.
-
-Tue Sep 20 11:42:30 EDT 1994
- Fix bug in comparing identically named common blocks, in which
-all components have the same names and types, but at least one is
-dimensioned (1) and the other is not dimensioned. Example:
- subroutine foo
- common /ab/ a
- a=1. !!! translated correctly to ab_1.a = (float)1.;
- end
- subroutine goo
- common /ab/ a(1)
- a(1)=2. !!! translated erroneously to ab_1.a[0] = (float)2.
- end
-
-Tue Sep 27 23:47:34 EDT 1994
- Fix bug introduced 16 Sept. 1994: don't add _a_ to C keywords
-used as external names. In fact, return to earlier behavior of
-appending __ to C keywords unless they are used as external names,
-in which case they get just one underscore appended.
- Adjust constant handling so integer and logical PARAMETERs retain
-type information, particularly under -I2. Example:
- SUBROUTINE FOO
- INTEGER I
- INTEGER*1 I1
- INTEGER*2 I2
- INTEGER*4 I4
- LOGICAL L
- LOGICAL*1 L1
- LOGICAL*2 L2
- LOGICAL*4 L4
- PARAMETER (L=.FALSE., L1=.FALSE., L2=.FALSE., L4=.FALSE.)
- PARAMETER (I=0,I1=0,I2=0,I4=0)
- CALL DUMMY(I, I1, I2, I4, L, L1, L2, L4)
- END
- f2c.1t: Change f\^2c to f2c (omit half-narrow space) in line following
-".SH NAME" for benefit of systems that cannot cope with troff commands
-in this context.
-
-Wed Sep 28 12:45:19 EDT 1994
- libf77: s_cmp.c fix glitch in -DKR_headers version introduced
-12 days ago.
-
-Thu Oct 6 09:46:53 EDT 1994
- libi77: util.c: omit f__mvgbt (which is never used).
- f2c.h: change "long" to "long int" to facilitate the adjustments
-by means of sed described above. Comment out unused typedef of Long.
-
-Fri Oct 21 18:02:24 EDT 1994
- libf77: add s_catow.c and adjust README to point out that changing
-"s_cat.o" to "s_catow.o" in the makefile will permit the target of a
-concatenation to appear on its right-hand side (contrary to the
-Fortran 77 Standard and at the cost of some run-time efficiency).
-
-Wed Nov 2 00:03:58 EST 1994
- Adjust -g output to contain only one #line line per statement,
-inserting \ before the \n ending lines broken because of their
-length [this insertion was recanted 10 Dec. 1994]. This change
-accommodates an idiocy in the ANSI/ISO C standard, which leaves
-undefined the behavior of #line lines that occur within the arguments
-to a macro call.
-
-Wed Nov 2 14:44:27 EST 1994
- libi77: under compilation with -DALWAYS_FLUSH, flush buffers at
-the end of each write statement, and test (via the return from
-fflush) for write failures, which can be caught with an ERR=
-specifier in the write statement. This extra flushing slows
-execution, but can abort execution or alter the flow of control
-when a disk fills up.
- f2c/src/io.c: Add ERR= test to e_wsle invocation (end of
-list-directed external output) to catch write failures when libI77
-is compiled with -DALWAYS_FLUSH.
-
-Thu Nov 3 10:59:13 EST 1994
- Fix bug in handling dimensions involving certain intrinsic
-functions of constant expressions: the expressions, rather than
-pointers to them, were passed. Example:
- subroutine subtest(n,x)
- real x(2**n,n) ! pow_ii(2,n) was called; now it's pow_ii(&c__2,n)
- x(2,2)=3.
- end
-
-Tue Nov 8 23:56:30 EST 1994
- malloc.c: remove assumption that only malloc calls sbrk. This
-appears to make malloc.c useful on RS6000 systems.
-
-Sun Nov 13 13:09:38 EST 1994
- Turn off constant folding of integers used in floating-point
-expressions, so the assignment in
- subroutine foo(x)
- double precision x
- x = x*1000000*500000
- end
-is rendered as
- *x = *x * 1000000 * 500000;
-rather than as
- *x *= 1783793664;
-
-Sat Dec 10 16:31:40 EST 1994
- Supply a better error message (than "Impossible type 14") for
- subroutine foo
- foo = 3
- end
- Under -g, convey name of included files to #line lines.
- Recant insertion of \ introduced (under -g) 2 Nov. 1994.
-
-Thu Dec 15 14:33:55 EST 1994
- New command-line option -Idir specifies directories in which to
-look for non-absolute include files (after looking in the directory
-of the current input file). There can be several -Idir options, each
-specifying one directory. All -Idir options are considered, from
-left to right, until a suitably named file is found. The -I2 and -I4
-command-line options have precedence, so directories named 2 or 4
-must be spelled by some circumlocation, such as -I./2 .
- f2c.ps updated to mention the new -Idir option, correct a typo,
-and bring the man page at the end up to date.
- lex.c: fix bug in reading line numbers in #line lines.
- fc updated to pass -Idir options to f2c.
-
-Thu Dec 29 09:48:03 EST 1994
- Fix bug (e.g., addressing fault) in diagnosing inconsistency in
-the type of function eta in the following example:
- function foo(c1,c2)
- double complex foo,c1,c2
- double precision eta
- foo = eta(c1,c2)
- end
- function eta(c1,c2)
- double complex eta,c1,c2
- eta = c1*c2
- end
-
-Mon Jan 2 13:27:26 EST 1995
- Retain casts for SNGL (or FLOAT) that were erroneously optimized
-away. Example:
- subroutine foo(a,b)
- double precision a,b
- a = float(b) ! now rendered as *a = (real) (*b);
- end
- Use float (rather than double) temporaries in certain expressions
-of type complex. Example: the temporary for sngl(b) in
- complex a
- double precision b
- a = sngl(b) - (3.,4.)
-is now of type float.
-
-Fri Jan 6 00:00:27 EST 1995
- Adjust intrinsic function cmplx to act as dcmplx (returning
-double complex rather than complex) if either of its args is of
-type double precision. The double temporaries used prior to 2 Jan.
-1995 previously gave it this same behavior.
-
-Thu Jan 12 12:31:35 EST 1995
- Adjust -krd to use double temporaries in some calculations of
-type complex.
- libf77: pow_[dhiqrz][hiq].c: adjust x**i to work on machines
-that sign-extend right shifts when i is the most negative integer.
-
-Wed Jan 25 00:14:42 EST 1995
- Fix memory fault in handling overlapping initializations in
- block data
- common /zot/ d
- double precision d(3)
- character*6 v(4)
- real r(2)
- equivalence (d(3),r(1)), (d(1),v(1))
- data v/'abcdef', 'ghijkl', 'mnopqr', 'stuvwx'/
- data r/4.,5./
- end
- names.c: add "far", "huge", "near" to c_keywords (causing them
-to have __ appended when used as local variables).
- libf77: add s_copyow.c, an alternative to s_copy.c for handling
-(illegal) character assignments where the right- and left-hand
-sides overlap, as in a(2:4) = a(1:3).
-
-Thu Jan 26 14:21:19 EST 1995
- libf77: roll s_catow.c and s_copyow.c into s_cat.c and s_copy.c,
-respectively, allowing the left-hand side of a character assignment
-to appear on its right-hand side unless s_cat.c and s_copy.c are
-compiled with -DNO_OVERWRITE (which is a bit more efficient).
-Fortran 77 forbids the left-hand side from participating in the
-right-hand side (of a character assignment), but Fortran 90 allows it.
- libi77: wref.c: fix glitch in printing the exponent of 0 when
-GOOD_SPRINTF_EXPONENT is not #defined.
-
-Fri Jan 27 12:25:41 EST 1995
- Under -C++ -ec (or -C++ -e1c), surround struct declarations with
- #ifdef __cplusplus
- extern "C" {
- #endif
-and
- #ifdef __cplusplus
- }
- #endif
-(This isn't needed with cfront, but apparently is necessary with
-some other C++ compilers.)
- libf77: minor tweak to s_copy.c: copy forward whenever possible
-(for better cache behavior).
-
-Wed Feb 1 10:26:12 EST 1995
- Complain about parameter statements that assign values to dummy
-arguments, as in
- subroutine foo(x)
- parameter(x = 3.4)
- end
-
-Sat Feb 4 20:22:02 EST 1995
- fc: omit "lib=/lib/num/lib.lo".
-
-Wed Feb 8 08:41:14 EST 1995
- Minor changes to exec.c, putpcc.c to avoid "bad tag" or "error
-in frexpr" with certain invalid Fortran.
-
-Sat Feb 11 08:57:39 EST 1995
- Complain about integer overflows, both in simplifying integer
-expressions, and in converting integers from decimal to binary.
- Fix a memory fault in putcx1() associated with invalid input.
-
-Thu Feb 23 11:20:59 EST 1995
- Omit MAXTOKENLEN; realloc token if necessary (to handle very long
-strings).
-
-Fri Feb 24 11:02:00 EST 1995
- libi77: iio.c: z_getc: insert (unsigned char *) to allow internal
-reading of characters with high-bit set (on machines that sign-extend
-characters).
-
-Tue Mar 14 18:22:42 EST 1995
- Fix glitch (in io.c) in handling 0-length strings in format
-statements, as in
- write(*,10)
- 10 format(' ab','','cd')
- libi77: lread.c and rsfe.c: adjust s_rsle and s_rsfe to check for
-end-of-file (to prevent infinite loops with empty read statements).
-
-Wed Mar 22 10:01:46 EST 1995
- f2c.ps: adjust discussion of -P on p. 7 to reflect a change made
-3 Feb. 1993: -P no longer implies -A.
-
-Fri Apr 21 18:35:00 EDT 1995
- fc script: remove absolute paths (since PATH specifies only standard
-places). On most systems, it's still necessary to adjust the PATH
-assignment at the start of fc to fit the local conventions.
-
-Fri May 26 10:03:17 EDT 1995
- fc script: add recognition of -P and .P files.
- libi77: iio.c: z_wnew: fix bug in handling T format items in internal
-writes whose last item is written to an earlier position than some
-previous item.
-
-Wed May 31 11:39:48 EDT 1995
- libf77: added subroutine exit(rc) (with integer return code rc),
-which works like a stop statement but supplies rc as the program's
-return code.
-
-Fri Jun 2 11:56:50 EDT 1995
- Fix memory fault in
- parameter (x=2.)
- data x /2./
- end
-This now elicits two error messages; the second ("too many
-initializers"), though not desirable, seems hard to eliminate
-without considerable hassle.
-
-Mon Jul 17 23:24:20 EDT 1995
- Fix botch in simplifying constants in certain complex
-expressions. Example:
- subroutine foo(s,z)
- double complex z
- double precision s, M, P
- parameter ( M = 100.d0, P = 2.d0 )
- z = M * M / s * dcmplx (1.d0, P/M)
-*** The imaginary part of z was miscomputed ***
- end
- Under -ext, complain about nonintegral dimensions.
-
-Fri Jul 21 11:18:36 EDT 1995
- Fix glitch on line 159 of init.c: change
- "(shortlogical *)0)",
-to
- "(shortlogical *)0",
-This affects multiple entry points when some but not all have
-arguments of type logical*2.
- libi77: adjust lwrite.c, wref.c, wrtfmt.c so compiling with
--DWANT_LEAD_0 causes formatted writes of floating-point numbers of
-magnitude < 1 to have an explicit 0 before the decimal point (if the
-field-width permits it). Note that the Fortran 77 Standard leaves it
-up to the implementation whether to supply these superfluous zeros.

-Tue Aug 1 09:25:56 EDT 1995
- Permit real (or double precision) parameters in dimension expressions.
-
-Mon Aug 7 08:04:00 EDT 1995
- Append "_eqv" rather than just "_" to names that that appear in
-EQUIVALENCE statements as well as structs in f2c.h (to avoid a
-conflict when these names also name common blocks).
-
-Tue Aug 8 12:49:02 EDT 1995
- Modify yesterday's change: merge st_fields with c_keywords, to
-cope with equivalences introduced to permit initializing numeric
-variables with character data. DATA statements causing these
-equivalences can appear after executable statements, so the only
-safe course is to rename all local variable with names in the
-former st_fields list. This has the unfortunate side effect that
-the common local variable "i" will henceforth be renamed "i__".
-
-Wed Aug 30 00:19:32 EDT 1995
- libf77: add F77_aloc, now used in s_cat and system_ (to allocate
-memory and check for failure in so doing).
- libi77: improve MSDOS logic in backspace.c.
-
-Wed Sep 6 09:06:19 EDT 1995
- libf77: Fix return type of system_ (integer) under -DKR_headers.
- libi77: Move some f_init calls around for people who do not use
-libF77's main(); now open and namelist read statements that are the
-first I/O statements executed should work right in that context.
-Adjust namelist input to treat a subscripted name whose subscripts do
-not involve colons similarly to the name without a subscript: accept
-several values, stored in successive elements starting at the
-indicated subscript. Adjust namelist output to quote character
-strings (avoiding confusion with arrays of character strings).
-
-Thu Sep 7 00:36:04 EDT 1995
- Fix glitch in integer*8 exponentiation function: it's pow_qq, not
-pow_qi.
- libi77: fix some bugs with -DAllow_TYQUAD (for integer*8); when
-looking for the &name that starts NAMELIST input, treat lines whose
-first nonblank character is something other than &, $, or ? as
-comment lines (i.e., ignore them), unless rsne.c is compiled with
--DNo_Namelist_Comments.
-
-Thu Sep 7 09:05:40 EDT 1995
- libi77: rdfmt.c: one more tweak for -DAllow_TYQUAD.
-
-Tue Sep 19 00:03:02 EDT 1995
- Adjust handling of floating-point subscript bounds (a questionable
-f2c extension) so subscripts in the generated C are of integral type.
- Move #define of roundup to proc.c (where its use is commented out);
-version.c left at 19950918.
-
-Wed Sep 20 17:24:19 EDT 1995
- Fix bug in handling ichar() under -h.
-
-Thu Oct 5 07:52:56 EDT 1995
- libi77: wrtfmt.c: fix bug with t editing (f__cursor was not always
-zeroed in mv_cur).
-
-Tue Oct 10 10:47:54 EDT 1995
- Under -ext, warn about X**-Y and X**+Y. Following the original f77,
-f2c treats these as X**(-Y) and X**(+Y), respectively. (They are not
-allowed by the official Fortran 77 Standard.) Some Fortran compilers
-give a bizarre interpretation to larger contexts, making multiplication
-noncommutative: they treat X**-Y*Z as X**(-Y*Z) rather than X**(-Y)*Z,
-which, following the rules of Fortran 77, is the same as (X**(-Y))*Z.
-
-Wed Oct 11 13:27:05 EDT 1995
- libi77: move defs of f__hiwater, f__svic, f__icptr from wrtfmt.c
-to err.c. This should work around a problem with buggy loaders and
-sometimes leads to smaller executable programs.
-
-Sat Oct 21 23:54:22 EDT 1995
- Under -h, fix bug in the treatment of ichar('0') in arithmetic
-expressions.
- Demote to -dneg (a new command-line option not mentioned in the
-man page) imitation of the original f77's treatment of unary minus
-applied to a REAL operand (yielding a DOUBLE PRECISION result).
-Previously this imitation (which was present for debugging) occurred
-under (the default) -!R. It is still suppressed by -R.
-
-Tue Nov 7 23:52:57 EST 1995
- Adjust assigned GOTOs to honor SAVE declarations.
- Add comments about ranlib to lib[FI]77/README and makefile.
-
-Tue Dec 19 22:54:06 EST 1995
- libf77: s_cat.c: fix bug when 2nd or later arg overlaps lhs.
-
-Tue Jan 2 17:54:00 EST 1996
- libi77: rdfmt.c: move #include "ctype.h" up before "stdlib.h"; no
-change to Version.c.
-
-Sun Feb 25 22:20:20 EST 1996
- Adjust expr.c to permit raising the integer constants 1 and -1 to
-negative constant integral powers.
- Avoid faulting when -T and -d are not followed by a directory name
-(immediately, without intervening spaces).
-
-Wed Feb 28 12:49:01 EST 1996
- Fix a glitch in handling complex parameters assigned a "wrong" type.
-Example:
- complex d, z
- parameter(z = (0d0,0d0))
- data d/z/ ! elicited "non-constant initializer"
- call foo(d)
- end
-
-Thu Feb 29 00:53:12 EST 1996
- Fix bug in handling character parameters assigned a char() value.
-Example:
- character*2 b,c
- character*1 esc
- parameter(esc = char(27))
- integer i
- data (b(i:i),i=1,2)/esc,'a'/
- data (c(i:i),i=1,2)/esc,'b'/ ! memory fault
- call foo(b,c)
- end
-
-Fri Mar 1 23:44:51 EST 1996
- Fix glitch in evaluating .EQ. and .NE. when both operands are
-logical constants (.TRUE. or .FALSE.).
-
-Fri Mar 15 17:29:54 EST 1996
- libi77: lread.c, rsfe.c: honor END= in READ stmts with empty iolist.
-
-Tue Mar 19 23:08:32 EST 1996
- lex.c: arrange for a "statement" consisting of a single short bogus
-keyword to elicit an error message showing the whole keyword. The
-error message formerly omitted the last letter of the bad keyword.
- libf77: s_cat.c: supply missing break after overlap detection.
-
-Mon May 13 23:35:26 EDT 1996
- Recognize Fortran 90's /= as a synonym for .NE.. (<> remains a
-synonym for .NE..)
- Emit an empty int function of no arguments to supply an external
-name to named block data subprograms (so they can be called somewhere
-to force them to be loaded from a library).
- Fix bug (memory fault) in handling the following illegal Fortran:
- parameter(i=1)
- equivalence(i,j)
- end
- Treat cdabs, cdcos, cdexp, cdlog, cdsin, and cdsqrt as synonyms for
-the double complex intrinsics zabs, zcos, zexp, zlog, zsin, and zsqrt,
-respectively, unless -cd is specified.
- Recognize the Fortran 90 bit-manipulation intrinsics btest, iand,
-ibclr, ibits, ibset, ieor, ior, ishft, and ishftc, unless -i90 is
-specified. Note that iand, ieor, and ior are thus now synonyms for
-"and", "xor", and "or", respectively.
- Add three macros (bit_test, bit_clear, bit_set) to f2c.h for use
-with btest, ibclr, and ibset, respectively. Add new functions
-[lq]bit_bits, [lq]bit_shift, and [lq]_bit_cshift to libF77 for
-use with ibits, ishft, and ishftc, respectively.
- Add integer function ftell(unit) (returning -1 on error) and
-subroutine fseek(unit, offset, whence, *) to libI77 (with branch to
-label * on error).
-
-Tue May 14 23:21:12 EDT 1996
- Fix glitch (possible memory fault, or worse) in handling multiple
-entry points with names over 28 characters long.
-
-Mon Jun 10 01:20:16 EDT 1996
- Update netlib E-mail and ftp addresses in f2c/readme and
-f2c/src/readme (which are different files) -- to reflect the upcoming
-breakup of AT&T.
- libf77: trivial tweaks to F77_aloc.c and system_.c; Version.c not
-changed.
- libi77: Adjust rsli.c and lread.c so internal list input with too
-few items in the input string will honor end= .
-
-Mon Jun 10 22:59:57 EDT 1996
- Add Bits_per_Byte to sysdep.h and adjust definition of Table_size
-to depend on Bits_per_Byte (forcing Table_size to be a power of 2); in
-lex.c, change "comstart[c & 0xfff]" to "comstart[c & (Table_size-1)]"
-to avoid an out-of-range subscript on end-of-file.
-
-Wed Jun 12 00:24:28 EDT 1996
- Fix bug in output.c (dereferencing a freed pointer) revealed in
- print * !np in out_call in output.c clobbered by free
- end !during out_expr.
-
-Wed Jun 19 08:12:47 EDT 1996
- f2c.h: add types uinteger, ulongint (for libF77); add qbit_clear
-and qbit_set macros (in a commented-out section) for integer*8.
- For integer*8, use qbit_clear and qbit_set for ibclr and ibset.
- libf77: add casts to unsigned in [lq]bitshft.c.
-
-Thu Jun 20 13:30:43 EDT 1996
- Complain at character*(*) in common (rather than faulting).
- Fix bug in recognizing hex constants that start with "16#" (e.g.,
-16#1234abcd, which is a synonym for z'1234abcd').
- Fix bugs in constant folding of expressions involving btest, ibclr,
-and ibset.
- Fix bug in constant folding of rshift(16#80000000, -31) (on a 32-bit
-machine; more generally, the bug was in constant folding of
-rshift(ibset(0,NBITS-1), 1-NBITS) when f2c runs on a machine with
-long ints having NBITS bits.
-
-Mon Jun 24 07:58:53 EDT 1996
- Adjust struct Literal and newlabel() function to accommodate huge
-source files (with more than 32767 newlabel() invocations).
- Omit .c file when the .f file has a missing final end statement.
-
-Wed Jun 26 14:00:02 EDT 1996
- libi77: Add discussion of MXUNIT (highest allowed Fortran unit number)
-to libI77/README.
-
-Fri Jun 28 14:16:11 EDT 1996
- Fix glitch with -onetrip: the temporary variable used for nonconstant
-initial loop variable values was recycled too soon. Example:
- do i = j+1, k
- call foo(i+1) ! temp for j+1 was reused here
- enddo
- end
-
-Tue Jul 2 16:11:27 EDT 1996
- formatdata.c: add a 0 to the end of the basetype array (for TYBLANK)
-(an omission that was harmless on most machines).
- expr.c: fix a dereference of NULL that was only possible with buggy
-input, such as
- subroutine $sub(s) ! the '$' is erroneous
- character s*(*)
- s(1:) = ' '
- end
-
-Sat Jul 6 00:44:56 EDT 1996
- Fix glitch in the intrinsic "real" function when applied to a
-complex (or double complex) variable and passed as an argument to
-some intrinsic functions. Example:
- complex a
- b = sqrt(a)
- end
- Fix glitch (only visible if you do not use f2c's malloc and the
-malloc you do use is defective in the sense that malloc(0) returns 0)
-in handling include files that end with another include (perhaps
-followed by comments).
- Fix glitch with character*(*) arguments named "h" and "i" when
-the body of the subroutine invokes the intrinsic LEN function.
- Arrange that after a previous "f2c -P foo.f" has produced foo.P,
-running "f2c foo.P foo.f" will produce valid C when foo.f contains
- call sub('1234')
- end
- subroutine sub(msg)
- end
-Specifically, the length argument in "call sub" is now suppressed.
-With or without foo.P, it is also now suppressed when the order of
-subprograms in file foo.f is reversed:
- subroutine sub(msg)
- end
- call sub('1234')
- end
- Adjust copyright notices to reflect AT&T breakup.
-
-Wed Jul 10 09:25:49 EDT 1996
- Fix bug (possible memory fault) in handling erroneously placed
-and inconsistent declarations. Example that faulted:
- character*1 w(8)
- call foo(w)
- end
- subroutine foo(m)
- data h /0.5/
- integer m(2) ! should be before data
- end
- Fix bug (possible fault) in handling illegal "if" constructions.
-Example (that faulted):
- subroutine foo(i,j)
- if (i) then ! bug: i is integer, not logical
- else if (j) then ! bug: j is integer, not logical
- endif
- end
- Fix glitch with character*(*) argument named "ret_len" to a
-character*(*) function.
-
-Wed Jul 10 23:04:16 EDT 1996
- Fix more glitches in the intrinsic "real" function when applied to a
-complex (or double complex) variable and passed as an argument to
-some intrinsic functions. Example:
- complex a, b
- r = sqrt(real(conjg(a))) + sqrt(real(a*b))
- end
-
-Thu Jul 11 17:27:16 EDT 1996
- Fix a memory fault associated with complicated, illegal input.
-Example:
- subroutine goo
- character a
- call foo(a) ! inconsistent with subsequent def and call
- end
- subroutine foo(a)
- end
- call foo(a)
- end
-
-Wed Jul 17 19:18:28 EDT 1996
- Fix yet another case of intrinsic "real" applied to a complex
-argument. Example:
- complex a(3)
- x = sqrt(real(a(2))) ! gave error message about bad tag
- end
-
-Mon Aug 26 11:28:57 EDT 1996
- Tweak sysdep.c for non-Unix systems in which process ID's can be
-over 5 digits long.
-
-Tue Aug 27 08:31:32 EDT 1996
- Adjust the ishft intrinsic to use unsigned right shifts. (Previously,
-a negative constant second operand resulted in a possibly signed shift.)
-
-Thu Sep 12 14:04:07 EDT 1996
- equiv.c: fix glitch with -DKR_headers.
- libi77: fmtlib.c: fix bug in printing the most negative integer.
-
-Fri Sep 13 08:54:40 EDT 1996
- Diagnose some illegal appearances of substring notation.
-
-Tue Sep 17 17:48:09 EDT 1996
- Fix fault in handling some complex parameters. Example:
- subroutine foo(a)
- double complex a, b
- parameter(b = (0,1))
- a = b ! f2c faulted here
- end
-
-Thu Sep 26 07:47:10 EDT 1996
- libi77: fmt.h: for formatted writes of negative integer*1 values,
-make ic signed on ANSI systems. If formatted writes of integer*1
-values trouble you when using a K&R C compiler, switch to an ANSI
-compiler or use a compiler flag that makes characters signed.
-
-Tue Oct 1 14:41:36 EDT 1996
- Give a better error message when dummy arguments appear in data
-statements.
-
-Thu Oct 17 13:37:22 EDT 1996
- Fix bug in typechecking arguments to character and complex (or
-double complex) functions; the bug could cause length arguments
-for character arguments to be omitted on invocations appearing
-textually after the first invocation. For example, in
- subroutine foo
- character c
- complex zot
- call goo(zot(c), zot(c))
- end
-the length was omitted from the second invocation of zot, and
-there was an erroneous error message about inconsistent calling
-sequences.
-
-Wed Dec 4 13:59:14 EST 1996
- Fix bug revealed by
- subroutine test(cdum,rdum)
- complex cdum
- rdum=cos(real(cdum)) ! "Unexpected tag 3 in opconv_fudge"
- end
- Fix glitch in parsing "DO 10 D0 = 1, 10".
- Fix glitch in parsing
- real*8 x
- real*8 x ! erroneous "incompatible type" message
- call foo(x)
- end
-
-Mon Dec 9 23:15:02 EST 1996
- Fix glitch in parameter adjustments for arrays whose lower
-bound depends on a scalar argument. Example:
- subroutine bug(p,z,m,n)
- integer z(*),m,n
- double precision p(z(m):z(m) + n) ! p_offset botched
- call foo(p(0), p(n))
- end
- libi77: complain about non-positive rec= in direct read and write
-statements.
- libf77: trivial adjustments; Version.c not changed.
-
-Wed Feb 12 00:18:03 EST 1997
- output.c: fix (seldom problematic) glitch in out_call: put parens
-around the ... in a test of the form "if (q->tag == TADDR && ...)".
- vax.c: fix bug revealed in the "psi_offset =" assignment in the
-following example:
- subroutine foo(psi,m)
- integer z(100),m
- common /a/ z
- double precision psi(z(m):z(m) + 10)
- call foo(m+1, psi(0),psi(10))
- end
-
-Mon Feb 24 23:44:54 EST 1997
- For consistency with f2c's current treatment of adjacent character
-strings in FORMAT statements, recognize a Hollerith string following
-a string (and merge adjacent strings in FORMAT statements).
-
-Wed Feb 26 13:41:11 EST 1997
- New libf2c.zip, a combination of the libf77 and libi77 bundles (and
-available only by ftp).
- libf77: adjust functions with a complex output argument to permit
-aliasing it with input arguments. (For now, at least, this is just
-for possible benefit of g77.)
- libi77: tweak to ftell_.c for systems with strange definitions of
-SEEK_SET, etc.
-
-Tue Apr 8 20:57:08 EDT 1997
- libf77: [cz]_div.c: tweaks invisible on most systems (that may
-improve things slightly with optimized compilation on systems that use
-gratuitous extra precision).
- libi77: fmt.c: adjust to complain at missing numbers in formats
-(but still treat missing ".nnn" as ".0").
-
-Fri Apr 11 14:05:57 EDT 1997
- libi77: err.c: attempt to make stderr line buffered rather than
-fully buffered. (Buffering is needed for format items T and TR.)
-
-Thu Apr 17 22:42:43 EDT 1997
- libf77: add F77_aloc.o to makefile (and makefile.u in libf2c.zip).
-
-Fri Apr 25 19:32:09 EDT 1997
- libf77: add [de]time_.c (which may give trouble on some systems).
-
-Tue May 27 09:18:52 EDT 1997
- libi77: ftell_.c: fix typo that caused the third argument to be
-treated as 2 on some systems.
-
-Mon Jun 9 00:04:37 EDT 1997
- libi77 (and libf2c.zip): adjust include order in err.c lread.c wref.c
-rdfmt.c to include fmt.h (etc.) after system includes. Version.c not
-changed.
-
-Mon Jul 21 16:04:54 EDT 1997
- proc.c: fix glitch in logic for "nonpositive dimension" message.
- libi77: inquire.c: always include string.h (for possible use with
--DNON_UNIX_STDIO); Version.c not changed.
-
-Thu Jul 24 17:11:23 EDT 1997
- Tweak "Notice" to reflect the AT&T breakup -- we missed it when
-updating the copyright notices in the source files last summer.
- Adjust src/makefile so malloc.o is not used by default, but can
-be specified with "make MALLOC=malloc.o".
- Add comments to src/README about the "CRAY" T3E.
-
-Tue Aug 5 14:53:25 EDT 1997
- Add definition of calloc to malloc.c; this makes f2c's malloc
-work on some systems where trouble hitherto arose because references
-to calloc brought in the system's malloc. (On sensible systems,
-calloc is defined separately from malloc. To avoid confusion on
-other systems, f2c/malloc.c now defines calloc.)
- libi77: lread.c: adjust to accord with a change to the Fortran 8X
-draft (in 1990 or 1991) that rescinded permission to elide quote marks
-in namelist input of character data; to get the old behavior, compile
-with F8X_NML_ELIDE_QUOTES #defined. wrtfmt.o: wrt_G: tweak to print
-the right number of 0's for zero under G format.
-
-Sat Aug 16 05:45:32 EDT 1997
- libI77: iio.c: fix bug in internal writes to an array of character
-strings that sometimes caused one more array element than required by
-the format to be blank-filled. Example: format(1x).

-If your compiler does not recognize ANSI C headers,
-compile with KR_headers defined: either add -DKR_headers
-to the definition of CFLAGS in the makefile, or insert
-
-#define KR_headers
-
-at the top of f2c.h , cabs.c , main.c , and sig_die.c .
-
-Under MS-DOS, compile s_paus.c with -DMSDOS.
-
-If you have a really ancient K&R C compiler that does not understand
-void, add -Dvoid=int to the definition of CFLAGS in the makefile.
-
-If you use a C++ compiler, first create a local f2c.h by appending
-f2ch.add to the usual f2c.h, e.g., by issuing the command
- make f2c.h
-which assumes f2c.h is installed in /usr/include .
-
-If your system lacks onexit() and you are not using an ANSI C
-compiler, then you should compile main.c, s_paus.c, s_stop.c, and
-sig_die.c with NO_ONEXIT defined. See the comments about onexit in
-the makefile.
-
-If your system has a double drem() function such that drem(a,b)
-is the IEEE remainder function (with double a, b), then you may
-wish to compile r_mod.c and d_mod.c with IEEE_drem defined.
-On some systems, you may also need to compile with -Ddrem=remainder .
-
-To check for transmission errors, issue the command
- make check
-This assumes you have the xsum program whose source, xsum.c,
-is distributed as part of "all from f2c/src". If you do not
-have xsum, you can obtain xsum.c by sending the following E-mail
-message to netlib@netlib.bell-labs.com
- send xsum.c from f2c/src
-
-The makefile assumes you have installed f2c.h in a standard
-place (and does not cause recompilation when f2c.h is changed);
-f2c.h comes with "all from f2c" (the source for f2c) and is
-available separately ("f2c.h from f2c").
-
-Most of the routines in libF77 are support routines for Fortran
-intrinsic functions or for operations that f2c chooses not
-to do "in line". There are a few exceptions, summarized below --
-functions and subroutines that appear to your program as ordinary
-external Fortran routines.
-
-1. CALL ABORT prints a message and causes a core dump.
-
-2. ERF(r) and DERF(d) and the REAL and DOUBLE PRECISION
- error functions (with x REAL and d DOUBLE PRECISION);
- DERF must be declared DOUBLE PRECISION in your program.
- Both ERF and DERF assume your C library provides the
- underlying erf() function (which not all systems do).
-
-3. ERFC(r) and DERFC(d) are the complementary error functions:
- ERFC(r) = 1 - ERF(r) and DERFC(d) = 1.d0 - DERFC(d)
- (except that their results may be more accurate than
- explicitly evaluating the above formulae would give).
- Again, ERFC and r are REAL, and DERFC and d are DOUBLE
- PRECISION (and must be declared as such in your program),
- and ERFC and DERFC rely on your system's erfc().
-
-4. CALL GETARG(n,s), where n is an INTEGER and s is a CHARACTER
- variable, sets s to the n-th command-line argument (or to
- all blanks if there are fewer than n command-line arguments);
- CALL GETARG(0,s) sets s to the name of the program (on systems
- that support this feature). See IARGC below.
-
-5. CALL GETENV(name, value), where name and value are of type
- CHARACTER, sets value to the environment value, $name, of
- name (or to blanks if $name has not been set).
-
-6. NARGS = IARGC() sets NARGS to the number of command-line
- arguments (an INTEGER value).
-
-7. CALL SIGNAL(n,func), where n is an INTEGER and func is an
- EXTERNAL procedure, arranges for func to be invoked when
- signal n occurs (on systems where this makes sense).
-
-8. CALL SYSTEM(cmd), where cmd is of type CHARACTER, passes
- cmd to the system's command processor (on systems where
- this can be done).
-
-The makefile does not attempt to compile pow_qq.c, qbitbits.c,
-and qbitshft.c, which are meant for use with INTEGER*8. To use
-INTEGER*8, you must modify f2c.h to declare longint and ulongint
-appropriately; then add pow_qq.o to the POW = line in the makefile,
-and add " qbitbits.o qbitshft.o" to the makefile's F90BIT = line.
-
-Following Fortran 90, s_cat.c and s_copy.c allow the target of a
-(character string) assignment to be appear on its right-hand, at
-the cost of some extra overhead for all run-time concatenations.
-If you prefer the extra efficiency that comes with the Fortran 77
-requirement that the left-hand side of a character assignment not
-be involved in the right-hand side, compile s_cat.c and s_copy.c
-with -DNO_OVERWRITE .
-
-If your system lacks a ranlib command, you don't need it.
-Either comment out the makefile's ranlib invocation, or install
-a harmless "ranlib" command somewhere in your PATH, such as the
-one-line shell script
-
- exit 0
-
-or (on some systems)
-
- exec /usr/bin/ar lts $1 >/dev/null

-If your compiler does not recognize ANSI C headers,
-compile with KR_headers defined: either add -DKR_headers
-to the definition of CFLAGS in the makefile, or insert
-
-#define KR_headers
-
-at the top of f2c.h and fmtlib.c .
-
-
-If you have a really ancient K&R C compiler that does not understand
-void, add -Dvoid=int to the definition of CFLAGS in the makefile.
-
-If you use a C++ compiler, first create a local f2c.h by appending
-f2ch.add to the usual f2c.h, e.g., by issuing the command
- make f2c.h
-which assumes f2c.h is installed in /usr/include .
-
-If your system lacks /usr/include/fcntl.h , then you
-should simply create an empty fcntl.h in this directory.
-If your compiler then complains about creat and open not
-having a prototype, compile with OPEN_DECL defined.
-On many systems, open and creat are declared in fcntl.h .
-
-If your system has /usr/include/fcntl.h, you may need to add
--D_POSIX_SOURCE to the makefile's definition of CFLAGS.
-
-If your system's sprintf does not work the way ANSI C
-specifies -- specifically, if it does not return the
-number of characters transmitted -- then insert the line
-
-#define USE_STRLEN
-
-at the end of fmt.h . This is necessary with
-at least some versions of Sun and DEC software.
-In particular, if you get a warning about an improper
-pointer/integer combination in compiling wref.c, then
-you need to compile with -DUSE_STRLEN .
-
-If your system's fopen does not like the ANSI binary
-reading and writing modes "rb" and "wb", then you should
-compile open.c with NON_ANSI_RW_MODES #defined.
-
-If you get error messages about references to cf->_ptr
-and cf->_base when compiling wrtfmt.c and wsfe.c or to
-stderr->_flag when compiling err.c, then insert the line
-
-#define NON_UNIX_STDIO
-
-at the beginning of fio.h, and recompile everything (or
-at least those modules that contain NON_UNIX_STDIO).
-
-Unformatted sequential records consist of a length of record
-contents, the record contents themselves, and the length of
-record contents again (for backspace). Prior to 17 Oct. 1991,
-the length was of type int; now it is of type long, but you
-can change it back to int by inserting
-
-#define UIOLEN_int
-
-at the beginning of fio.h. This affects only sue.c and uio.c .
-
-On VAX, Cray, or Research Tenth-Edition Unix systems, you may
-need to add -DVAX, -DCRAY, or -DV10 (respectively) to CFLAGS
-to make fp.h work correctly. Alternatively, you may need to
-edit fp.h to suit your machine.
-
-You may need to supply the following non-ANSI routines:
-
- fstat(int fileds, struct stat *buf) is similar
-to stat(char *name, struct stat *buf), except that
-the first argument, fileds, is the file descriptor
-returned by open rather than the name of the file.
-fstat is used in the system-dependent routine
-canseek (in the libI77 source file err.c), which
-is supposed to return 1 if it's possible to issue
-seeks on the file in question, 0 if it's not; you may
-need to suitably modify err.c . On non-UNIX systems,
-you can avoid references to fstat and stat by compiling
-with NON_UNIX_STDIO defined; in that case, you may need
-to supply access(char *Name,0), which is supposed to
-return 0 if file Name exists, nonzero otherwise.
-
- char * mktemp(char *buf) is supposed to replace the
-6 trailing X's in buf with a unique number and then
-return buf. The idea is to get a unique name for
-a temporary file.
-
-On non-UNIX systems, you may need to change a few other,
-e.g.: the form of name computed by mktemp() in endfile.c and
-open.c; the use of the open(), close(), and creat() system
-calls in endfile.c, err.c, open.c; and the modes in calls on
-fopen() and fdopen() (and perhaps the use of fdopen() itself
--- it's supposed to return a FILE* corresponding to a given
-an integer file descriptor) in err.c and open.c (component ufmt
-of struct unit is 1 for formatted I/O -- text mode on some systems
--- and 0 for unformatted I/O -- binary mode on some systems).
-Compiling with -DNON_UNIX_STDIO omits all references to creat()
-and almost all references to open() and close(), the exception
-being in the function f__isdev() (in open.c).
-
-For MS-DOS, compile all of libI77 with -DMSDOS (which implies
--DNON_UNIX_STDIO). You may need to make other compiler-dependent
-adjustments; for example, for Turbo C++ you need to adjust the mktemp
-invocations and to #undef ungetc in lread.c and rsne.c .
-
-If you want to be able to load against libI77 but not libF77,
-then you will need to add sig_die.o (from libF77) to libI77.
-
-If you wish to use translated Fortran that has funny notions
-of record length for direct unformatted I/O (i.e., that assumes
-RECL= values in OPEN statements are not bytes but rather counts
-of some other units -- e.g., 4-character words for VMS), then you
-should insert an appropriate #define for url_Adjust at the
-beginning of open.c . For VMS Fortran, for example,
-#define url_Adjust(x) x *= 4
-would suffice.
-
-To check for transmission errors, issue the command
- make check
-This assumes you have the xsum program whose source, xsum.c,
-is distributed as part of "all from f2c/src". If you do not
-have xsum, you can obtain xsum.c by sending the following E-mail
-message to netlib@netlib.bell-labs.com
- send xsum.c from f2c/src
-
-The makefile assumes you have installed f2c.h in a standard
-place (and does not cause recompilation when f2c.h is changed);
-f2c.h comes with "all from f2c" (the source for f2c) and is
-available separately ("f2c.h from f2c").
-
-By default, Fortran I/O units 5, 6, and 0 are pre-connected to
-stdin, stdout, and stderr, respectively. You can change this
-behavior by changing f_init() in err.c to suit your needs.
-Note that f2c assumes READ(*... means READ(5... and WRITE(*...
-means WRITE(6... . Moreover, an OPEN(n,... statement that does
-not specify a file name (and does not specify STATUS='SCRATCH')
-assumes FILE='fort.n' . You can change this by editing open.c
-and endfile.c suitably.
-
-Unless you adjust the "#define MXUNIT" line in fio.h, Fortran units
-0, 1, ..., 99 are available, i.e., the highest allowed unit number
-is MXUNIT - 1.
-
-Lines protected from compilation by #ifdef Allow_TYQUAD
-are for a possible extension to 64-bit integers in which
-integer = int = 32 bits and longint = long = 64 bits.
-
-Extensions (Feb. 1993) to NAMELIST processing:
- 1. Reading a ? instead of &name (the start of a namelist) causes
-the namelist being sought to be written to stdout (unit 6);
-to omit this feature, compile rsne.c with -DNo_Namelist_Questions.
- 2. Reading the wrong namelist name now leads to an error message
-and an attempt to skip input until the right namelist name is found;
-to omit this feature, compile rsne.c with -DNo_Bad_Namelist_Skip.
- 3. Namelist writes now insert newlines before each variable; to omit
-this feature, compile xwsne.c with -DNo_Extra_Namelist_Newlines.
- 4. (Sept. 1995) When looking for the &name that starts namelist
-input, lines whose first non-blank character is something other
-than &, $, or ? are treated as comment lines and ignored, unless
-rsne.c is compiled with -DNo_Namelist_Comments.
-
-Nonstandard extension (Feb. 1993) to open: for sequential files,
-ACCESS='APPEND' (or access='anything else starting with "A" or "a"')
-causes the file to be positioned at end-of-file, so a write will
-append to the file.
-
-Some buggy Fortran programs use unformatted direct I/O to write
-an incomplete record and later read more from that record than
-they have written. For records other than the last, the unwritten
-portion of the record reads as binary zeros. The last record is
-a special case: attempting to read more from it than was written
-gives end-of-file -- which may help one find a bug. Some other
-Fortran I/O libraries treat the last record no differently than
-others and thus give no help in finding the bug of reading more
-than was written. If you wish to have this behavior, compile
-uio.c with -DPad_UDread .
-
-If you want to be able to catch write failures (e.g., due to a
-disk being full) with an ERR= specifier, compile dfe.c, due.c,
-sfe.c, sue.c, and wsle.c with -DALWAYS_FLUSH. This will lead to
-slower execution and more I/O, but should make ERR= work as
-expected, provided fflush returns an error return when its
-physical write fails.
-
-Carriage controls are meant to be interpreted by the UNIX col
-program (or a similar program). Sometimes it's convenient to use
-only ' ' as the carriage control character (normal single spacing).
-If you compile lwrite.c and wsfe.c with -DOMIT_BLANK_CC, formatted
-external output lines will have an initial ' ' quietly omitted,
-making use of the col program unnecessary with output that only
-has ' ' for carriage control.
-
-The Fortran 77 Standard leaves it up to the implementation whether
-formatted writes of floating-point numbers of absolute value < 1 have
-a zero before the decimal point. By default, libI77 omits such
-superfluous zeros, but you can cause them to appear by compiling
-lwrite.c, wref.c, and wrtfmt.c with -DWANT_LEAD_0 .
-
-If your system lacks a ranlib command, you don't need it.
-Either comment out the makefile's ranlib invocation, or install
-a harmless "ranlib" command somewhere in your PATH, such as the
-one-line shell script
-
- exit 0
-
-or (on some systems)
-
- exec /usr/bin/ar lts $1 >/dev/null
-
-Most of the routines in libI77 are support routines for Fortran
-I/O. There are a few exceptions, summarized below -- I/O related
-functions and subroutines that appear to your program as ordinary
-external Fortran routines.
-
-1. CALL FLUSH flushes all buffers.
-
-2. FTELL(i) is an INTEGER function that returns the current
- offset of Fortran unit i (or -1 if unit i is not open).
-
-3. CALL FSEEK(i, offset, whence, *errlab) attemps to move
- Fortran unit i to the specified offset: absolute offset
- if whence = 0; relative to the current offset if whence = 1;
- relative to the end of the file if whence = 2. It branches
- to label errlab if unit i is not open or if the call
- otherwise fails.

- GNU LIBRARY GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- Copyright (C) 1991 Free Software Foundation, Inc.
- 675 Mass Ave, Cambridge, MA 02139, 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., 675 Mass Ave, Cambridge, MA 02139, 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.
-
- <signature of Ty Coon>, 1 April 1990
- Ty Coon, President of Vice
-
-That's all there is to it!

-g77 libU77
-----------
-
-This directory contains an implementation of most of the `traditional'
-Unix libU77 routines, mostly an interface to libc and libm routines
-and some extra ones for time and date etc. It's intended for use with
-g77, to whose configuration procedure it's currently tied, but should
-be compatible with f2c otherwise, if using the same f2c.h.
-
-The contents of libU77 and its interfaces aren't consistent across
-implementations. This one is mostly taken from documentation for (an
-old version of) the Convex implementation and the v2 SunPro one.
-As of g77 version 0.5.20, most of these routines have been made
-into g77 intrinsics. Some routines have a version with a name prefixed
-by `vxt', corresponding to the VMS Fortran versions, and these should
-be integrated with g77's intrinsics visibility control.
-
-A few routines are currently missing; in the case of `fork', for
-instance, because they're probably not useful, and in the case of
-`qsort' and those for stream-based i/o handling, because they need
-more effort/research. The configuration should weed out those few
-which correspond to facilities which may not be present on some Unix
-systems, such as symbolic links. It's unclear whether the interfaces
-to the native library random number routines should be retained, since
-their implementation is likely to be something one should avoid
-assiduously.
-
-This library has been tested it under SunOS4.1.3 and Irix5.2 and there
-has been some feedback from Linux; presumably potential problems lie
-mainly with systems with impoverished native C library support which
-haven't been properly taken care of with autoconf.
-
-There's another GPL'd implementation of this stuff which I only found
-out about recently (despite having looked) and I haven't yet checked
-how they should be amalgamated.

-
-====== old index for f2c, now "readme from f2c" ============
-
-FILES:
-
-f2c.h Include file necessary for compiling output of the converter.
- See the second NOTE below.
-
-f2c.1 Man page for f2c.
-
-f2c.1t Source for f2c.1 (to be processed by troff -man or nroff -man).
-
-libf77 Library of non I/O support routines the generated C may need.
- Fortran main programs result in a C function named MAIN__ that
- is meant to be invoked by the main() in libf77.
-
-libi77 Library of Fortran I/O routines the generated C may need.
- Note that some vendors (e.g., BSD, Sun and MIPS) provide a
- libF77 and libI77 that are incompatible with f2c -- they
- provide some differently named routines or routines with the
- names that f2c expects, but with different calling sequences.
- On such systems, the recommended procedure is to merge
- libf77 and libi77 into a single library, say libf2c, and to
- install it where you can access it by specifying -lf2c . The
- definition of link_msg in sysdep.c assumes this arrangement.
-
- Both libf77 and libi77 are bundles, meant to be unpacked by the
- Bourne (or Korn) shell. MS-DOS users can use the MKS Toolkit
- to unpack libf77 and libi77.
-
-libf2c.zip
- Only available by ftp: combination of libf77 and libi77, with
- Unix and PC makefiles.
-
-f2c.ps Postscript for a technical report on f2c. After you strip the
- mail header, the first line should be "%!PS".
-
-fixes The complete change log, reporting bug fixes and other changes.
- (Some recent change-log entries are given below).
-
-fc A shell script that uses f2c and imitates much of the behavior
- of commonly found f77 commands. You will almost certainly
- need to adjust some of the shell-variable assignments to make
- this script work on your system.
-
-
-SUBDIRECTORY:
-
-f2c/src Source for the converter itself, including a file of checksums
- and source for a program to compute the checksums (to verify
- correct transmission of the source), is available: ask netlib
- (e.g., netlib@netlib.bell-labs.com) to
- send all from f2c/src
- If the checksums show damage to just a few source files, or if
- the change log file (see "fixes" below) reports corrections to
- some source files, you can request those files individually
- "from f2c/src". For example, to get defs.h and xsum0.out, you
- would ask netlib to
- send defs.h xsum0.out from f2c/src
- "all from f2c/src" is about 640 kilobytes long; for convenience
- (and checksums), it includes copies of f2c.h, f2c.1, and f2c.1t.
-
- Tip: if asked to send over 99,000 bytes in one request, netlib
- breaks the shipment into 1000 line pieces and sends each piece
- separately (since otherwise some mailers might gag). To avoid
- the hassle of reassembling the pieces, try to keep each request
- under 99,000 bytes long. The final number in each line of
- xsum0.out gives the length of each file in f2c/src. For
- example,
- send exec.c expr.c from f2c/src
- send format.c format_data.c from f2c/src
- will give you slightly less hassle than
- send exec.c expr.c format.c format_data.c from f2c/src
- Alternatively, if all the mailers in your return path allow
- long messages, you can supply an appropriate mailsize line in
- your netlib request, e.g.
- mailsize 200k
- send exec.c expr.c format.c format_data.c from f2c/src
-
- If you have trouble generating gram.c, you can ask netlib to
- send gram.c from f2c/src
- Then `xsum gram.c` should report
- gram.c 5529f4f 58745
- Alternatively, if you have bison, you might get a working
- gram.c by saying
- make gram.c YACC=bison YFLAGS=-y
- (but please do not complain if this gives a bad gram.c).
-
-NOTE: For now, you may exercise f2c by sending netlib a message whose
- first line is "execute f2c" and whose remaining lines are
- the Fortran 77 source that you wish to have converted.
- Return mail brings you the resulting C, with f2c's error
- messages between #ifdef uNdEfInEd and #endif at the end.
- (To understand line numbers in the error messages, regard
- the "execute f2c" line as line 0. It is stripped away by
- the netlib software before f2c sees your Fortran input.)
- Options described in the man page may be transmitted to
- netlib by having the first line of input be a comment
- whose first 6 characters are "c$f2c " and whose remaining
- characters are the desired options, e.g., "c$f2c -R -u".
-
- You may say "execute f2c" in the Subject line instead of (but
- *not* in addition to) in the first line of the message body.
-
- The incoming Fortran is saved, at least for a while. Don't
- send any secrets!
-
-
-BUGS: Please send bug reports (including the shortest example
- you can find that illustrates the bug) to research!dmg
- or dmg@bell-labs.com . You might first check whether
- the bug goes away when you turn optimization off.
-
-
-NOTE: f2c.h defines several types, e.g., real, integer, doublereal.
- The definitions in f2c.h are suitable for most machines, but if
- your machine has sizeof(double) > 2*sizeof(long), you may need
- to adjust f2c.h appropriately. f2c assumes
- sizeof(doublecomplex) = 2*sizeof(doublereal)
- sizeof(doublereal) = sizeof(complex)
- sizeof(doublereal) = 2*sizeof(real)
- sizeof(real) = sizeof(integer)
- sizeof(real) = sizeof(logical)
- sizeof(real) = 2*sizeof(shortint)
- EQUIVALENCEs may not be translated correctly if these
- assumptions are violated.
-
- On machines, such as those using a DEC Alpha processor, on
- which sizeof(short) == 2, sizeof(int) == sizeof(float) == 4,
- and sizeof(long) == sizeof(double) == 8, it suffices to
- modify f2c.h by removing the first occurrence of "long "
- on each line containing "long ", e.g., by issuing the
- commands
- mv f2c.h f2c.h0
- sed 's/long //' f2c.h0 >f2c.h
- On such machines, one can enable INTEGER*8 by uncommenting
- the typedef of longint in f2c.h, so it reads
- typedef long longint;
- by compiling libI77 with -DAllow_TYQUAD, and by adjusting
- libF77/makefile as described in libF77/README.
-
- Some machines may have sizeof(int) == 4 and
- sizeof(long long) == 8. On such machines, adjust f2c.h
- by changing "long int " to "long long ", e.g., by saying
- mv f2c.h f2c.h0
- sed 's/long int /long long /' f2c.h0 >f2c.h
- One can enable INTEGER*8 on such machines as described
- above, but with
- typedef long long longint;
-
- There exists a C compiler that objects to the lines
- typedef VOID C_f; /* complex function */
- typedef VOID H_f; /* character function */
- typedef VOID Z_f; /* double complex function */
- in f2c.h . If yours is such a compiler, do two things:
- 1. Complain to your vendor about this compiler bug.
- 2. Find the line
- #define VOID void
- in f2c.h and change it to
- #define VOID int
- (For readability, the f2c.h lines shown above have had two
- tabs inserted before their first character.)
-
-FTP: All the material described above is now available by anonymous
- ftp from netlib.bell-labs.com (login: anonymous; Password: your
- E-mail address; cd netlib/f2c). Note that you can say, e.g.,
-
- cd /netlib/f2c/src
- binary
- prompt
- mget *.Z
-
- to get all the .Z files in src. You must uncompress the .Z
- files once you have a copy of them, e.g., by
-
- uncompress *.Z
-
- Subdirectory msdos contains two PC versions of f2c,
- f2c.exe.Z and f2cx.exe.Z; the latter uses extended memory.
- The README in that directory provides more details.
-
- Changes appear first in the f2c files available by E-mail
- from netlib@netlib.bell-labs.com. If the deamons work right,
- changed files are available the next day by ftp from
- netlib.bell-labs.com. In due course, they reach other netlib servers.
-
-CHANGE NOTIFICATION:
- Send the E-mail message
- subscribe f2c
- to netlib@netlib.bell-labs.com to request notification of new and
- changed f2c files. (Beware that automatically sent change
- notifications may reach you before changes have reached
- ftp://netlib.bell-labs.com/netlib/f2c or to other netlib servers.)
- Send the E-mail message
- unsubscribe f2c
- to recant your notification request.
-
------------------
-Recent change log (partial)
------------------
-
-Mon May 13 23:35:26 EDT 1996
- Recognize Fortran 90's /= as a synonym for .NE.. (<> remains a
-synonym for .NE..)
- Emit an empty int function of no arguments to supply an external
-name to named block data subprograms (so they can be called somewhere
-to force them to be loaded from a library).
- Fix bug (memory fault) in handling the following illegal Fortran:
- parameter(i=1)
- equivalence(i,j)
- end
- Treat cdabs, cdcos, cdexp, cdlog, cdsin, and cdsqrt as synonyms for
-the double complex intrinsics zabs, zcos, zexp, zlog, zsin, and zsqrt,
-respectively, unless -cd is specified.
- Recognize the Fortran 90 bit-manipulation intrinsics btest, iand,
-ibclr, ibits, ibset, ieor, ior, ishft, and ishftc, unless -i90 is
-specified. Note that iand, ieor, and ior are thus now synonyms for
-"and", "xor", and "or", respectively.
- Add three macros (bit_test, bit_clear, bit_set) to f2c.h for use
-with btest, ibclr, and ibset, respectively. Add new functions
-[lq]bit_bits, [lq]bit_shift, and [lq]_bit_cshift to libF77 for
-use with ibits, ishft, and ishftc, respectively.
- Add integer function ftell(unit) (returning -1 on error) and
-subroutine fseek(unit, offset, whence, *) to libI77 (with branch to
-label * on error).
-
-Tue May 14 23:21:12 EDT 1996
- Fix glitch (possible memory fault, or worse) in handling multiple
-entry points with names over 28 characters long.
-
-Mon Jun 10 01:20:16 EDT 1996
- Update netlib E-mail and ftp addresses in f2c/readme and
-f2c/src/readme (which are different files) -- to reflect the upcoming
-breakup of AT&T.
- libf77: trivial tweaks to F77_aloc.c and system_.c; Version.c not
-changed.
- libi77: Adjust rsli.c and lread.c so internal list input with too
-few items in the input string will honor end= .
-
-Mon Jun 10 22:59:57 EDT 1996
- Add Bits_per_Byte to sysdep.h and adjust definition of Table_size
-to depend on Bits_per_Byte (forcing Table_size to be a power of 2); in
-lex.c, change "comstart[c & 0xfff]" to "comstart[c & (Table_size-1)]"
-to avoid an out-of-range subscript on end-of-file.
-
-Wed Jun 12 00:24:28 EDT 1996
- Fix bug in output.c (dereferencing a freed pointer) revealed in
- print * !np in out_call in output.c clobbered by free
- end !during out_expr.
-
-Wed Jun 19 08:12:47 EDT 1996
- f2c.h: add types uinteger, ulongint (for libF77); add qbit_clear
-and qbit_set macros (in a commented-out section) for integer*8.
- For integer*8, use qbit_clear and qbit_set for ibclr and ibset.
- libf77: add casts to unsigned in [lq]bitshft.c.
-
-Thu Jun 20 13:30:43 EDT 1996
- Complain at character*(*) in common (rather than faulting).
- Fix bug in recognizing hex constants that start with "16#" (e.g.,
-16#1234abcd, which is a synonym for z'1234abcd').
- Fix bugs in constant folding of expressions involving btest, ibclr,
-and ibset.
- Fix bug in constant folding of rshift(16#80000000, -31) (on a 32-bit
-machine; more generally, the bug was in constant folding of
-rshift(ibset(0,NBITS-1), 1-NBITS) when f2c runs on a machine with
-long ints having NBITS bits.
-
-Mon Jun 24 07:58:53 EDT 1996
- Adjust struct Literal and newlabel() function to accommodate huge
-source files (with more than 32767 newlabel() invocations).
- Omit .c file when the .f file has a missing final end statement.
-
-Wed Jun 26 14:00:02 EDT 1996
- libi77: Add discussion of MXUNIT (highest allowed Fortran unit number)
-to libI77/README.
-
-Fri Jun 28 14:16:11 EDT 1996
- Fix glitch with -onetrip: the temporary variable used for nonconstant
-initial loop variable values was recycled too soon. Example:
- do i = j+1, k
- call foo(i+1) ! temp for j+1 was reused here
- enddo
- end
-
-Tue Jul 2 16:11:27 EDT 1996
- formatdata.c: add a 0 to the end of the basetype array (for TYBLANK)
-(an omission that was harmless on most machines).
- expr.c: fix a dereference of NULL that was only possible with buggy
-input, such as
- subroutine $sub(s) ! the '$' is erroneous
- character s*(*)
- s(1:) = ' '
- end
-
-Sat Jul 6 00:44:56 EDT 1996
- Fix glitch in the intrinsic "real" function when applied to a
-complex (or double complex) variable and passed as an argument to
-some intrinsic functions. Example:
- complex a
- b = sqrt(real(a))
- end
- Fix glitch (only visible if you do not use f2c's malloc and the
-malloc you do use is defective in the sense that malloc(0) returns 0)
-in handling include files that end with another include (perhaps
-followed by comments).
- Fix glitch with character*(*) arguments named "h" and "i" when
-the body of the subroutine invokes the intrinsic LEN function.
- Arrange that after a previous "f2c -P foo.f" has produced foo.P,
-running "f2c foo.P foo.f" will produce valid C when foo.f contains
- call sub('1234')
- end
- subroutine sub(msg)
- end
-Specifically, the length argument in "call sub" is now suppressed.
-With or without foo.P, it is also now suppressed when the order of
-subprograms in file foo.f is reversed:
- subroutine sub(msg)
- end
- call sub('1234')
- end
- Adjust copyright notices to reflect AT&T breakup.
-
-Wed Jul 10 09:25:49 EDT 1996
- Fix bug (possible memory fault) in handling erroneously placed
-and inconsistent declarations. Example that faulted:
- character*1 w(8)
- call foo(w)
- end
- subroutine foo(m)
- data h /0.5/
- integer m(2) ! should be before data
- end
- Fix bug (possible fault) in handling illegal "if" constructions.
-Example (that faulted):
- subroutine foo(i,j)
- if (i) then ! bug: i is integer, not logical
- else if (j) then ! bug: j is integer, not logical
- endif
- end
- Fix glitch with character*(*) argument named "ret_len" to a
-character*(*) function.
-
-Wed Jul 10 23:04:16 EDT 1996
- Fix more glitches in the intrinsic "real" function when applied to a
-complex (or double complex) variable and passed as an argument to
-some intrinsic functions. Example:
- complex a, b
- r = sqrt(real(conjg(a))) + sqrt(real(a*b))
- end
-
-Thu Jul 11 17:27:16 EDT 1996
- Fix a memory fault associated with complicated, illegal input.
-Example:
- subroutine goo
- character a
- call foo(a) ! inconsistent with subsequent def and call
- end
- subroutine foo(a)
- end
- call foo(a)
- end
-
-Wed Jul 17 19:18:28 EDT 1996
- Fix yet another case of intrinsic "real" applied to a complex
-argument. Example:
- complex a(3)
- x = sqrt(real(a(2))) ! gave error message about bad tag
- end
-
-Mon Aug 26 11:28:57 EDT 1996
- Tweak sysdep.c for non-Unix systems in which process ID's can be
-over 5 digits long.
-
-Tue Aug 27 08:31:32 EDT 1996
- Adjust the ishft intrinsic to use unsigned right shifts. (Previously,
-a negative constant second operand resulted in a possibly signed shift.)
-
-Thu Sep 12 14:04:07 EDT 1996
- equiv.c: fix glitch with -DKR_headers.
- libi77: fmtlib.c: fix bug in printing the most negative integer.
-
-Fri Sep 13 08:54:40 EDT 1996
- Diagnose some illegal appearances of substring notation.
-
-Tue Sep 17 17:48:09 EDT 1996
- Fix fault in handling some complex parameters. Example:
- subroutine foo(a)

- libi77: fmt.h: for formatted writes of negative integer*1 values,
-make ic signed on ANSI systems. If formatted writes of integer*1
-values trouble you when using a K&R C compiler, switch to an ANSI
-compiler or use a compiler flag that makes characters signed.
-
-Tue Oct 1 14:41:36 EDT 1996
- Give a better error message when dummy arguments appear in data
-statements.
-
-Thu Oct 17 13:37:22 EDT 1996
- Fix bug in typechecking arguments to character and complex (or
-double complex) functions; the bug could cause length arguments
-for character arguments to be omitted on invocations appearing
-textually after the first invocation. For example, in
- subroutine foo
- character c
- complex zot
- call goo(zot(c), zot(c))
- end
-the length was omitted from the second invocation of zot, and
-there was an erroneous error message about inconsistent calling
-sequences.
-
-Wed Dec 4 13:59:14 EST 1996
- Fix bug revealed by
- subroutine test(cdum,rdum)
- complex cdum
- rdum=cos(real(cdum)) ! "Unexpected tag 3 in opconv_fudge"
- end
- Fix glitch in parsing "DO 10 D0 = 1, 10".
- Fix glitch in parsing
- real*8 x
- real*8 x ! erroneous "incompatible type" message
- call foo(x)
- end
- lib[FI]77/makefile: add comment about omitting -x under Solaris.
-
-Mon Dec 9 23:15:02 EST 1996
- Fix glitch in parameter adjustments for arrays whose lower
-bound depends on a scalar argument. Example:
- subroutine bug(p,z,m,n)
- integer z(*),m,n
- double precision p(z(m):z(m) + n) ! p_offset botched
- call foo(p(0), p(n))
- end
- libi77: complain about non-positive rec= in direct read and write
-statements.
- libf77: trivial adjustments; Version.c not changed.
-
-Wed Feb 12 00:18:03 EST 1997
- output.c: fix (seldom problematic) glitch in out_call: put parens
-around the ... in a test of the form "if (q->tag == TADDR && ...)".
- vax.c: fix bug revealed in the "psi_offset =" assignment in the
-following example:
- subroutine foo(psi,m)
- integer z(100),m
- common /a/ z
- double precision psi(z(m):z(m) + 10)
- call foo(m+1, psi(0),psi(10))
- end
-
-Mon Feb 24 23:44:54 EST 1997
- For consistency with f2c's current treatment of adjacent character
-strings in FORMAT statements, recognize a Hollerith string following
-a string (and merge adjacent strings in FORMAT statements).
-
-Wed Feb 26 13:41:11 EST 1997
- New libf2c.zip, a combination of the libf77 and libi77 bundles (and
-available only by ftp).
- libf77: adjust functions with a complex output argument to permit
-aliasing it with input arguments. (For now, at least, this is just
-for possible benefit of g77.)
- libi77: tweak to ftell_.c for systems with strange definitions of
-SEEK_SET, etc.
-
-Tue Apr 8 20:57:08 EDT 1997
- libf77: [cz]_div.c: tweaks invisible on most systems (that may
-improve things slightly with optimized compilation on systems that use
-gratuitous extra precision).
- libi77: fmt.c: adjust to complain at missing numbers in formats
-(but still treat missing ".nnn" as ".0").
-
-Fri Apr 11 14:05:57 EDT 1997
- libi77: err.c: attempt to make stderr line buffered rather than
-fully buffered. (Buffering is needed for format items T and TR.)
-
-Thu Apr 17 22:42:43 EDT 1997
- libf77: add F77_aloc.o to makefile (and makefile.u in libf2c.zip).
-
-Fri Apr 25 19:32:09 EDT 1997
- libf77: add [de]time_.c (which may give trouble on some systems).
-
-Tue May 27 09:18:52 EDT 1997
- libi77: ftell_.c: fix typo that caused the third argument to be
-treated as 2 on some systems.
-
-Mon Jun 9 00:04:37 EDT 1997
- libi77 (and libf2c.zip): adjust include order in err.c lread.c wref.c
-rdfmt.c to include fmt.h (etc.) after system includes. Version.c not
-changed.
-
-Mon Jun 9 14:29:13 EDT 1997
- src/gram.c updated; somehow it did not reflect the change of
-19961001 to gram.dcl.
-
-Mon Jul 21 16:04:54 EDT 1997
- proc.c: fix glitch in logic for "nonpositive dimension" message.
- libi77: inquire.c: always include string.h (for possible use with
--DNON_UNIX_STDIO); Version.c not changed.
-
-Thu Jul 24 17:11:23 EDT 1997
- Tweak "Notice" to reflect the AT&T breakup -- we missed it when
-updating the copyright notices in the source files last summer.
- Adjust src/makefile so malloc.o is not used by default, but can
-be specified with "make MALLOC=malloc.o".
- Add comments to src/README about the "CRAY" T3E.
-
-Tue Aug 5 14:53:25 EDT 1997
- Add definition of calloc to malloc.c; this makes f2c's malloc
-work on some systems where trouble hitherto arose because references
-to calloc brought in the system's malloc. (On sensible systems,
-calloc is defined separately from malloc. To avoid confusion on
-other systems, f2c/malloc.c now defines calloc.)
- libi77: lread.c: adjust to accord with a change to the Fortran 8X
-draft (in 1990 or 1991) that rescinded permission to elide quote marks
-in namelist input of character data; to get the old behavior, compile
-with F8X_NML_ELIDE_QUOTES #defined. wrtfmt.o: wrt_G: tweak to print
-the right number of 0's for zero under G format.
-
-Sat Aug 16 05:45:32 EDT 1997
- libI77: iio.c: fix bug in internal writes to an array of character
-strings that sometimes caused one more array element than required by
-the format to be blank-filled. Example: format(1x).
-
-Current timestamps of files in "all from f2c/src", sorted by time,
-appear below (mm/dd/year hh:mm:ss). To bring your source up to date,
-obtain source files with a timestamp later than the time shown in your
-version.c. Note that the time shown in the current version.c is the
-timestamp of the source module that immediately follows version.c below:
