| |
| Mainly stuff to improve handling of TYPE_CODE_REF values. |
| * valops.c (value_addr): If taking the addres of a |
| TYPE_CODE_REF, just cast the object to the corresponding |
| TYPE_CODE_PTR. This yields correct C++ semantics, and |
| preserves the location information, which has the nice effect |
| that &(&R) given the location containing R. |
| * values.c (value_copy): Make non-static (used by value_addr). |
| * eval.c (evaluate_subexp_for_address): Use the default |
| scheme (with value_addr) for a variable if it has TYPE_CODE_REF. |
| * valops.c (value_addr), eval.c (evaluate_subexp_for_address, |
| evaluate_subexp_with_coercion): Factor out some common |
| expressions into variables, for easier reading. |
| * findvar.c (locate_var_value): Remove code to handle |
| TYPE_CODE_REF - it should no longer be needed. |
| * valops.c (value_assign): Do a COERCE_REF on the |
| destination operand, for correct C++ semantics. |
| * valarith.c (value_x_binop): Ditto: De-reference C++ |
| references in the arguments. |
| * valops.c: ANSI-fy: bcopy->memcpy, bzero->memset. |
| |
| Sat Dec 28 11:30:26 1991 Per Bothner (bothner at cygnus.com) |
| |
| * dwarfread.c, coffread.c: Use INIT_CPLUS_SPECIFIC. |
| * symtab.c (gdb_mangle_name): Recognize and handle |
| constructors specially. |
| * symtab.c (check_stub_method): Test for failure from |
| cplus-demangle by calling error() instead of seg-faulting ... |
| |
| Fri Dec 27 22:21:30 1991 Fred Fish (fnf at cygnus.com) |
| |
| * defs.h: Add definition of null_cleanup() |
| |
| * procfs.c: Many small changes to add base support for a new |
| "info proc" command (currently only printing of the address |
| space mapping is implemented) and allow iteration over the |
| address space mapping, calling an arbitrary function for each |
| mapping (used for shared library support). |
| |
| * solib.c: Change all ifdefs that checked for "sun" to check |
| for "!SVR4_SHARED_LIBS" instead. Rewrite lookup_base() to |
| handle locating the debug base address even when not currently |
| stopped at the dynamic linker entry point. |
| |
| * utils.c: Add null_cleanup() as a known function that does |
| nothing to serve as a base for possibly long cleanup chains |
| with no specific "first cleanup" to serve as an anchor. |
| |
| * xm-sysv4.h: Add define of SVR4_SHARED_LIBS |
| |
| Fri Dec 27 10:11:33 1991 Per Bothner (bothner at cygnus.com) |
| |
| * arm-opcode.h, m88k-opcode.h, pn-opcode.h, np1-opcode.h, |
| pyr-opcode.h, tahoe-opcode, vax-opcode.h: Removed - |
| these are all essentially the same as the versions |
| in ../include/opcode. The remaining *-opcode.h here |
| are not quite so obviously the same, and need study. |
| * arm-pinsn.c, gould-pinsn.c, m88k-pinsn.c, pyr-pinsn.c, |
| tahoe-pinsn.c, vax-pinsn.c: Change so these include |
| opcode/FOO.h (actually ../include/opcode/FOO.h) |
| instead of the recenntly departed opcode-FOO.h files. |
| * sparc-pinsn.c: Now that we're using the much tighter |
| opcode table in ../include/opcode/sparc.h, we shouldn't |
| need to sort the opcodes before dis-assembly. |
| |
| * symtab.h, symmisc.c: Make cplus_struct_default be const. |
| * symtab.h, buildsym.c: Add and use INIT_CPLUS_SPECIFIC macro. |
| * symmisc.c: Remove unused 'nfields' variable. |
| * buildsym.h: Add extern decl of unknown_symtype_complaint, |
| since it used used by partial-stab.h (included two places). |
| * partial-stab.h: Re-arrange DBXREAD_ONLY #ifdefs so that |
| we should never hit the default case (until new stab codes |
| are added). Hence, we can leave the complaint in the |
| default case in even when DBXREAD_ONLY is off. |
| * partial_stab.h: Recognize a pair of N_SO stabs (one for the |
| directory, one for the filename proper) without peeking ahead. |
| * dbxread.c, mipsread.c: Because of previous change, don't need |
| ugly CHECK_SECOND_N_SO macro. |
| * buildsym.h, dbxread.c, mipsread.c: Make next_symbol_text a |
| macro that invokes a function pointer in next_symbol_text_func. |
| * mipsread.c: Added comments various places to |
| explain what is going on. |
| * mipsread.c (parse_symbol): Support the new (SGI-specific?) |
| symbol types stStruct, stUnion, and stEnum. |
| Also, some fixes in the code for dealing with tags. |
| * mipsread.c: Change handling of startup_file_start and _end |
| - now just use the textlow and texhigh of a psymtab |
| to check if we've found the startup-file. |
| * mipsread.c: Replace s_idx by global cur_sdx in many places. |
| This is so mips_next_symbol_text can get at it. |
| |
| Thu Dec 26 19:52:01 1991 Fred Fish (fnf at cygnus.com) |
| |
| * dbxread.c, symmisc.c: Move add_psymbol_to_plist() from |
| dbxread.c to symmisc and change name to add_psymbol_to_list. |
| Ditto for add_psymbol_addr_to_plist(). Also expand their |
| body to not use ADD_PSYMBOL_VT_TO_LIST. |
| |
| * dwarfread.c: Remove add_psymbol_to_list() and convert usages |
| to the ADD_PSYMBOL_TO_LIST macro. |
| |
| * ieee-float.c: Change "#ifdef DEBUG" to "#ifdef IEEE_DEBUG" |
| to avoid collision with the DEBUG for ADD_PSYMBOL_VT_TO_LIST. |
| |
| * partial-stab.h, symfile.h: Move definitions of the macros |
| ADD_PSYMBOL_TO_LIST and ADD_PSYMBOL_ADDR_TO_LIST from |
| partial-stab.h to symfile.h. They aren't stab specific. |
| Change ADD_PSYMBOL_VT_TO_LIST to use memcpy rather than strncpy. |
| |
| Tue Dec 24 11:38:08 1991 John Gilmore (gnu at cygnus.com) |
| |
| * Makefile.in: Roll VERSION to 4.3.2. |
| |
| Mon Dec 23 13:54:35 1991 Per Bothner (bothner at cygnus.com) |
| |
| * m68k-opcode.h, mips-opcode.h, sparc-opcode.h: Deleted. |
| * m68k-pinsn.c, mips-pinsn.c, sparc-pinsn.c: |
| Include <opcode/FOO.h> instead of <FOO-opcode.h>. |
| |
| * symtab.h, symtab.c, coffread.c, dwarfread.c, symmisc.c, |
| dbxread.c: The TYPE_CPLUS_SPECIFIC structure is now only |
| allocated when it is needed. Until it is needed, it points |
| to a shared statically allocated structure. |
| |
| * buildsym.h, buildsym.c, dbxread.c: Remove the kludgy code |
| in read_ofile_symtab to recognize two initial N_SO stabs, |
| and let process_on_symbol handle it. This is cleaner, more |
| efficient, and lets mipsread.c share the same code. |
| |
| * symfile.h, partial-stab.h: Move ADD_PSYMBOL_VT_TO_LIST |
| and related macros to here ... |
| * dbxread.c: ... from here. |
| * symmisc.c: Move the "overflow" handling from |
| ADD_PSYMBOL_VT_TO_LIST macro into new function extend_psymbol_list. |
| * dwarfread.c: Re-write add_psymbol_to_list to use |
| ADD_PSYMBOL_VT_TO_LIST macro. |
| |
| * mipsread.c: Extend mipsread.c to handle stabs-style symbols |
| encapsulated in ecoff symbols. This enable full g++ debugging. |
| * partial-stab.h: Move the code for pre-scanning symbols |
| and building psymtabs to an include file, out from dbxread.c. |
| This way, the same code can also be used by mipsread.c. |
| * dbxread.c, buildsym.h: Various changes to allow some functions |
| to be used by mipsread.c (also some arguable stylistic changes). |
| |
| * tm-mips.h: Define BLOCK_ADDRESS_ABSOLUTE, at least for now, |
| since mips-tfile puts relocatable addresses into LBRAC/RBRAC |
| stabs. |
| |
| * mipsread.c: Replace code to handle ambiguous tag blocks. |
| Instead of allocating a TYPE_CODE_UNDEF, guess (by looking |
| at types and offsets) if a tag is a struct, union, or enum. |
| Still patch it later if we find out for sure. |
| * mipsread.c: In various ways, replace Forin's |
| ideo-syncratic code by code that fits better with the |
| rest of gdb, for both stabs-based and ecoff-based symtabs. |
| E.g. use end_psymtab; don't do extra passes over FDR table to |
| pre-partition global data; don't use external symbols to |
| create static/global symbols (just put them in the |
| misc_vector); use ADD_PSYMBOL_TO_LIST macro; don't |
| sort psymtabs or symtabs; use obstacks more. |
| |
| * symtab.c, mipsread.c, dbxread.c, buildsym.c: |
| ANSIfy: Replace bcopy by memcpy, bzero by memset. |
| |
| Sun Dec 22 19:31:04 1991 Fred Fish (fnf at cygnus.com) |
| |
| * solib.c (locate_base): Fix uninitialized variable that was |
| causing return of random value to callee. |
| |
| * config/mh-amix, config/mh-i386v4: Change to find alloca by |
| compiling and linking alloca.c, even when it is not strictly |
| required. Also arrange to link with -ltermlib rather than |
| -ltermcap. |
| |
| * Makefile.in: Move TERMCAP definition to prior to inclusion |
| of host makefile fragments so it can be overridden. |
| |
| Fri Dec 20 16:33:39 1991 John Gilmore (gnu at cygnus.com) |
| |
| * xcoffread.c (read_symbol_lineno): Logic error in incrementing |
| symbol table entry number. (From Metin Ozisik.) |
| |
| Fri Dec 20 11:36:38 1991 Fred Fish (fnf at cygnus.com) |
| |
| * config/mh-i386v4: Change XM_CLIBS to "-lc /usr/ucblib/libucb.a" |
| so compiles with native compilers (without builtin alloca) can |
| pick up the version from the bsd emulation library. However, we |
| search the standard C library first so we don't pick up lots of |
| other broken stuff from libucb.a, that we *don't* want. |
| |
| * configure.in, tm-amix.h, tm-i386v4.h, xm-amix.h, xm-i386v4.h: |
| Change svr4 references to sysv4. |
| |
| * source.c: Move declaration of external function index to |
| front of file so it is in scope for all references. |
| |
| * utils.c (error, fatal): Make definitions consistent with |
| defs.h declarations (declared as "volatile void"). |
| |
| Fri Dec 20 10:55:36 1991 John Gilmore (gnu at cygnus.com) |
| |
| * rs6k-opcode.h: Bugfix sfe and stbrx. By Al Kossow. |
| |
| Wed Dec 18 17:09:06 1991 Stu Grossman (grossman at cygnus.com) |
| |
| * command.h, defs.h, eval.h, expression.h, remote-sa.sparc.c, |
| sparc-tdep.c, symtab.h, target.h, value.h, vx-share/ptrace.h, |
| vx-share/xdr_ptrace.h, vx-share/xdr_rdb.h: ANSIfy enums. |
| |
| Mon Dec 16 12:31:46 1991 Fred Fish (fnf at cygnus.com) |
| |
| * config/mt-amix, config/mt-i386v4: Add solib.o to TDEPFILES |
| for these SVR4 systems. |
| |
| * symfile.c (symbol_file_add): When verbose is set, print |
| the names of files from which symbols are being loaded, as |
| when from_tty is true. |
| |
| * solib.c: Completely reorganized (rewritten) to support |
| SVR4 shared libraries in a manner very close to the original |
| SunOS implementation. This support is expected to change and |
| become more general at some future time. The SVR4 version |
| does not yet work for attached processes, for example. |
| |
| * dwarfread.c: Arrange in dwarf_build_psymtabs() for the |
| relocation address to be valid whether or not symbols are |
| being read from a shared library or an executable. Use the |
| relocation address recorded in the psymtab when reading |
| full symbol tables (in read_ofile_symtab). Ensure that the |
| relocated address ranges are recorded in partial symtabs. |
| |
| * elfread.c: Add new function elf_interpreter() to return the |
| string from the ELF ".interp" section. This is the interpreter |
| that the kernel tries to run and feed the executable to. |
| Expand arguments to record_misc_function to include a type arg. |
| Modify elf_symtab_read() to supply the type arg, and to do symbol |
| relocations for symbols read in from shared libraries. |
| |
| * procfs.c: Add new functions proc_base_address() and |
| proc_address_to_fd(), used by shared library support. |
| |
| * tm-svr4.h: Add macros to support SVR4 shared libraries. |
| Definitions for SOLIB_ADD, SOLIB_CREATE_INFERIOR_HOOK, |
| CLEAR_SOLIB, and DISABLE_UNSETTABLE_BREAK. |
| |
| Fri Dec 13 20:11:26 1991 John Gilmore (gnu at cygnus.com) |
| |
| * infrun.c, remote-eb.c, remote-nindy.c, remote-vx.c: Remove |
| unused START_INFERIOR_HOOK. |
| |
| * remote-eb.c: Change timeout to 24 seconds (*10 fits in byte) |
| to account for slow loading from floppies. |
| (eb_create_inferior): New fn, from eb_start and |
| nindy_create_inferior. |
| (eb_close): Only use log_file if nonzero. |
| (eb_xfer_inferior_memory): If not writing, then read! |
| (eb_read_inferior_memory, eb_write_inferior_memory): Return length. |
| (eb_kill): A new no-op. |
| (eb_mourn_inferior): Remove breakpoints, then generically weep. |
| |
| Fri Dec 13 16:09:23 1991 Fred Fish (fnf at cygnus.com) |
| |
| * breakpoint.c, findvar.c, infrun.c, putenv.c, stack.c: Fix |
| miscellaneous comparisons of integer with NULL that elicit |
| compiler warnings about comparison of integer with pointer, when |
| NULL is ((void *) 0) rather than just a bare 0. |
| |
| Wed Dec 11 13:02:58 1991 John Gilmore (gnu at cygnus.com) |
| |
| * breakpoint.c (breakpoint_re_set_one): Disable each breakpoint |
| while we reset it, in case of problems. Print breakpoint number |
| in error messages. |
| |
| * buildsym.c (read_struct_type): Avoid sun3 compiler bug with |
| foo[--n]. |
| |
| * source.c (find_source_lines): If getting file mod time fails, |
| don't warn. |
| |
| * target.c (target_xfer_memory): If errno is set, return it, |
| rather than EIO. |
| |
| Tue Dec 10 04:07:22 1991 K. Richard Pixley (rich at rtl.cygnus.com) |
| |
| * Makefile.in: infodir belongs in datadir. |
| |
| Sun Dec 8 21:13:33 1991 Michael Tiemann (tiemann at sphagnum.cygnus.com) |
| |
| * symtab.h (struct fn_field): Add new fields `is_private', |
| `is_protected', `is_stub', making room by reducing the size of |
| `voffset'. |
| (struct fn_fieldlist): Delete the fields `private_fn_field_bits' |
| and `protected_fn_field_bits'. |
| (TYPE_FN_{PRIVATE,PROTECTED}_BITS): Deleted. |
| (SET_TYPE_FN_{PRIVATE,PROTECTED}): Deleted. |
| (TYPE_FN_{PRIVATE,PROTECTED}): Deleted. |
| (TYPE_FN_FIELD_{STUB,PRIVATE,PROTECTED}): New macros. |
| * valops.c, valprint.c, symtab.c: All callers updated. |
| |
| * buildsym.c (read_struct_type): Delete the `visibility' field |
| from `struct next_fnfield', and rework code so that visibility |
| info is stored into the fn_field directly. Also, hacked to set |
| TYPE_FN_FIELD_STUB for both static and normal member functions. |
| |
| Sat Dec 7 18:13:11 1991 Fred Fish (fnf at cygnus.com) |
| |
| * i386-tdep.c: Fix a problem on i386 systems where buffered code |
| stream access was failing to take into account the minimum size |
| granularity of the code section. For now, the buffering is simply |
| disabled. There is a similar problem in the i386 disassember code |
| that has not yet been fixed (FIXME). |
| |
| * gmalloc.c: Use macros to hide some of the ugly casting required |
| in the previously applied fix for pointers with high bits set. |
| |
| Sat Dec 7 16:49:35 1991 John Gilmore (gnu at cygnus.com) |
| |
| * Makefile.in: Roll VERSION to 4.3.1. |
| |
| Sat Dec 7 04:12:35 1991 John Gilmore (gnu at cygnus.com) |
| |
| GDB-4.3 release! |
| |
| * Makefile.in: Roll VERSION to 4.3 |
| * README, TODO, WHATS.NEW, depend: Update. |
| |
| * inflow.c (terminal_inferior): Avoid error msg if attached. |
| |
| * gmalloc.c: Fix bug that causes malloc & free to |
| fail on systems where pointers have the high bit set (0x800efcf0 |
| for example). The problem is that the difference between two |
| pointers is a signed integer, so the computation |
| |
| (char *) 0x800efcf0 - (char *) 0 |
| |
| yields a negative value. The sign of the result of the modulus |
| operator is machine dependent for negative operands, thus it is |
| possible for it to end up negative. From Fred Fish. |
| |
| Sat Dec 7 00:00:15 1991 K. Richard Pixley (rich at rtl.cygnus.com) |
| |
| * Makefile.in: install using INSTALL_PROGRAM and INSTALL_DATA. |
| added clean-info. added some standards.text support and made it |
| look like our other Makefiles. |
| |
| * configure.in: mark this directory target dependent. configure |
| now runs entirely in objdir so make existence tests and |
| references against ${srcdir}. |
| |
| Fri Dec 6 08:30:36 1991 Fred Fish (fnf at cygnus.com) |
| |
| * dwarfread.c (enum_type, struct_type): Fixes for opaque and |
| anonymous enumerations, structures, and unions. Now passes all |
| the current gdb test suite tests. |
| |
| Thu Dec 5 22:46:13 1991 K. Richard Pixley (rich at rtl.cygnus.com) |
| |
| * Makefile.in: idestdir and ddestdir go away. Added copyrights |
| and shift gpl to v2. Added ChangeLog if it didn't exist. docdir |
| and mandir now keyed off datadir by default. |
| |
| Thu Dec 5 21:53:21 1991 John Gilmore (gnu at cygnus.com) |
| |
| * symtab.c (decode_line_1): If SKIP_PROLOGUE leaves us in |
| mid-line, be more careful about possibly advancing to the next line. |
| |
| Thu Dec 5 18:59:51 1991 Michael Tiemann (tiemann at cygnus.com) |
| |
| * cplus-dem.c (cplus_demangle): Call `string_need' when |
| null-terminating a partially-computed string. |
| |
| Thu Dec 5 18:19:43 1991 Fred Fish (fnf at cygnus.com) |
| |
| * dwarfread.c (enum_type): Build a correct TYPE_NAME, add a |
| symbol to the symbol table for each member of the enum. |
| |
| * dwarfread.c (struct_type): Build a correct TYPE_NAME. |
| |
| * dwarfread.c (add_enum_psymbol): New function to extract enum |
| member names and add them to the partial symbol table while |
| building partial symbol tables. |
| |
| Thu Dec 5 17:31:05 1991 John Gilmore (gnu at cygnus.com) |
| |
| * symtab.c (check_stub_method): Must allocate two extra argument |
| slots (one for `this', one for arglist terminator). |
| |
| Thu Dec 5 10:51:05 1991 Fred Fish (fnf at cygnus.com) |
| |
| * inflow.c (child_terminal_info): Supply missing '"' character. |
| |
| * buildsym.c (define_symbol): Supply missing parenthesis. |
| |
| Thu Dec 5 03:34:21 1991 John Gilmore (gnu at cygnus.com) |
| |
| * coredep.c (fetch_core_registers): Fencepost error. Fixed by |
| Jay Lepreau <lepreau@cs.utah.edu>. |
| |
| * inflow.c: Remember whether GDB has a terminal. Avoid switching |
| terminals back and forth if we don't have one. |
| |
| * c-exp.y (parse_number): Zero is not an unsigned int constant! |
| * dbxread.c (read_dbx_symtab): Enum type numbers can be in (1,2) form. |
| |
| Improve type parsing. |
| * buildsym.c (define_symbol, read_range_type): Add |
| long_kludge_name that passes the names of range types being |
| defined, down to where we must choose between 'int' and 'long' |
| variants. This fails on Sun C anyway since the compiler itself is |
| confused between int and long. |
| (read_array_type, cleanup_undefined_types): Correct the size of |
| array type whose element-type size isn't immediately known. |
| |
| Early preparation to blow away many builtin types, building them |
| on the fly as needed. Don't compare types to builtin types with |
| ==; examine the relevant fields instead. |
| * coffread.c (process_coff_symbol: C_ARG, C_REGPARM): Avoid ==. |
| * buildsym.c (define_symbol, case 'p'): Avoid ==. |
| * valops.c (value_arg_coerce): Avoid ==. Don't assume host and |
| target types are the same. |
| * valprint.c (val_print): I finally understand arrays, remove FIXME. |
| |
| * symmisc.c (printpsyms_command): Reduce redundancy, and put all |
| addresses in GDB itself into parens for easy cleanup and diffing. |
| |
| Wed Dec 4 21:05:30 1991 Fred Fish (fnf at cygnus.com) |
| |
| * dwarfread (enum_type): Arrange for the order of enumeration |
| members to match the source code order; not the order in the |
| Dwarf information, which is explicitly reverse order. |
| |
| Wed Dec 4 18:24:39 1991 John Gilmore (gnu at cygnus.com) |
| |
| * main.c (input_from_terminal_p): Check whether GDB has a |
| terminal at all. |
| (initialize_main): Revise doc for `set editing'. |
| |
| Wed Dec 4 15:36:39 1991 Fred Fish (fnf at cygnus.com) |
| |
| * dwarfread.c (struct_type): Handle structures and unions which |
| contain DIE's other than just member dies. |
| |
| Wed Dec 4 01:59:05 1991 John Gilmore (gnu at cygnus.com) |
| |
| * symfile.c (reread_symbols): Avoid kludging mtime_set, now that |
| BFD is fixed. |
| |
| Tue Dec 3 17:24:57 1991 John Gilmore (gnu at cygnus.com) |
| |
| * Makefile.in: VERSION 4.2.96. |
| |
| * main.c (initialize_main): Revise command descriptions. |
| * command.c (show_user): `info user' -> `show user'. |
| * symtab.c (_initialize_symtab): Typo in `info types' desc. |
| |
| * coffread.c (coff_symfile_read): Avoid select_source_symtab, |
| since it is not needed and can cause errors when examining ".o"s. |
| (read_coff_symtab, decode_base_type): Use complain, not printf. |
| Print symbol name, not its number. |
| Remove "#if defined(clipper) #define BELIEVE_PCC_PROMOTION", which |
| someday should go in a clipper target config file. |
| |
| * symfile.c (compact_misc_function_vector): Handle empty vector. |
| (complain, clear_complaints, syms_from_objfile): Fix complaint |
| formatting. |
| * xcoffexec.c: Change syms_from_objfile caller. |
| |
| * sparc-xdep.c: Force tm-file as tm-sparc.h, to make it compile |
| when configured for cross debugging. FIXME, this needs a more |
| general solution. |
| |
| Mon Dec 2 11:04:05 1991 Per Bothner (bothner at cygnus.com) |
| |
| * mips-tdep.c (init_extra_frame_info): Float register |
| 'i' has gdb-internal number 'FP0+i', not '32+i'. |
| * mipsread.c (new_symbol): Translate g++ special |
| symbol "$t" to "this". |
| |
| Sat Nov 30 21:29:55 1991 Steve Chamberlain (sac at cygnus.com) |
| Changes due to include file renaming: |

| compiler generated tags to include symbols beginning with '.' as |
| well as '~'. |

| |
| * configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo: |
| Makefile fragments for various hosts and targets now come from |

| helpful compilers for anonymous structs, unions, and enums. |
| |

| |
| * procfs.c: Move inclusion of defs.h to before param.h, as in |

| |
| * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for |
| skipping function prologues, ala the other cpu families (i386, |

| m68k prologue skipping function by default. |
| |

| |
| * source.c (open_source_file): If openp fails, try again |
| using just the base (non-directory) part of the filename. |
| This solves various annoying problems, such as when the |
| source was compiled with an absolute pathname - and the |
| source files have moved. Or if the source was compiled |
| using a relative pathname, it can be more convenient |
| to just specific the source directory to the dir command. |
| |
| Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com) |
| |
| * cplus-dem.c (munge_function_name): Add missing third arg to |

| and condense_misc_bunches(), these are now done in elfread.c. |
| |
| * elfread.c: Add support for reading bfd canonical symbol tables |
| and generating misc function vector entries for global and |
| absolute symbols. Do calls to init_misc_bunches() and |
| condense_misc_bunches() where they will enclose all calls to |
| record_misc_function(), including those in dwarfread.c. |
| |
| Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com) |
| |
| * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm |

| FIXME: frame_locals_address should go away. |
| |
| * tm-delta88.h: Dump all the tdesc stuff. |
| Macros for all frame-related stuff call fns of same name. |

| flags since they are no longer used. |

| types in a function type. |
| * eval.c (parse_and_eval_type), value.h: New function, |
| parse_and_eval_type, is based on old code from check_stub_method. |

| |
| * coffread.c: Eliminate c_nsyms in favor of c_naux. |
| Complain if no auxents on .bf and .ef FCN symbols, and assume |
| lots of line numbers. |
| (init_linenos, enter_linenos): Use a sentinel at the end of the |
| read-in linenos, to make for a fast, safe loop-end test. |
| |
| Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com) |
| |
| * coffread.c (read_coff_symtab): coffread used to rely on the |
| x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a |
| function. Two of the formats I'm using (29k and 88k) don't seem to |
| set it. Ths patch to fcn_last_line and (enter_linenos) is an |
| attempt to use the actual size of the linno table in the file to set |
| the number of linenos to process. |
| |
| Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com) |
| |
| * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and |
| mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files |
| are created in place, so the mv fails, then the make continues. |
| |
| Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com) |
| |
| Add C++ as a separate language. |
| * defs.h (enum language): Add language_cplus. |
| * dwarfread.c (end_symtab): Support language_cplus. |
| * c-exp.y: Add new struct language_defn cplus_language_defn. |
| Don't set c to be the default language (see main.c). |
| * c-exp.y (yylex): Only look for field of this if |
| language is C++. (First difference from C!) |
| * language.c: Add case branches for C++ (currently, all |
| the same as C). Also, add c++ to "usage" note for "set lang". |
| * valprint.c (typedef_print). Add case branches for C++. |
| * main.c (main): New way to set initial language: Look at |
| file extension of psymtab containing main(). (Same as we |
| do for symtabs, but avoid loading the symtab yet.) |
| * symtab.c: New routine find_main_psymtab(), used by main() |
| to set initial language. |
| * symfile.c (allocate_symtab): Move code for mapping file |
| extensions-> languages to new deduce_language_from_filename(). |
| |
| Fix a C++ problem when looking for methods in super-classes. |
| There was confusion between base and derived types. |
| * valops.c (value_fn_field): Change function interface. |
| * values.c: Use new value_fn_field interface. |
| |
| Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com) |
| |
| * infrun.c: Fixed typo in comment. |
| * utils.c: All the v*fprintf emulation is now in libiberty, |
| so we can get rid of some junk. |
| * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco, |
| xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more. |
| * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL |
| type operands, as used by branch instructions. |
| * gmalloc.c: Fix prototype of memcpy. |
| * elfread.c: Comment out register_addr, since it conflicts |
| with the one in coredep.c. |
| * buildsym.h: Remove extern declarations of two functions |
| that are really static in buildsym.c. |
| * tm-mips.h: Add symbolic names for more registers. |
| * mips-xdep.c (store_inferior_registers): Use new register names. |
| * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now |
| only used for core files, not ptrace. Therefore, |
| the KERNEL_U_ADDR hack is no longer needed. |
| The mapping to ptrace number is now in in mips-xdep.c. |
| * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the |
| mapping from the old REGISTER_U_ADDR), and use it |
| in {fetch,store}_inferior_registers. |
| * mipsread.c: Rename #include ecoff.h to new name coff-mips.h. |
| * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame): |
| Save/restore FP regs correctly (?). |
| * dbxread.c: Remove duplicate define_symbol and type_synonym_name |
| (these had been previously moved to buildsym.c). |
| Hence, define_symbol becomes extern instead of static. |
| * buildsym.c (read_struct_type): Comment out bogus handling |
| of C++ operator methods. Minor hacking of reading of class |
| contexts. Make define_symbol non-static, so dbxread.c can call it. |
| |
| Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com) |
| |
| * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real |
| filename with error messages. |
| * stack.c (frame_select_command): Rename to select_frame_command |
| to avoid "fr" and "fra" having nonunique completions. |
| * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *. |
| (symfile_init): Print file format name when unable to handle it. |
| (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST. |
| * symmisc.c (free_symtab): Only free linetable if nonzero. |
| * symtab.h: Remove obsolete BLOCKLIST macros. |
| |
| Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com) |
| |
| * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure |
| that stop_step is 1 at bottom of main loop. I don't know why this |
| needs to be done, but it helps me sleep better at night. |
| |
| Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com) |
| |
| * main.c (initialize_history): Read history after reading all |
| init files. |
| |
| Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com) |
| |
| * buildsym.c: Break out initial malloc sizes. |
| (record_line): Record directly in a subfile. Alloc on demand. |
| (compare_line_numbers): Add from xcoffread.c. |
| (end_symtab): New params say whether to sort pendings and |
| linetable. Patch block stabs if defined. Shrink linetable before |
| allocating the symtab. |
| * buildsym.h: Delete line_vector* and prev_line_number. Add |
| global_stabs and file_stabs for xcoffread. |
| * dbxread.c (start_subfile): Move to buildsym. Change above calls. |
| * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST. |
| * symmisc.c, symtab.c: Cope with null LINETABLEs. |
| |
| * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO. |
| * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h, |
| tm-sparc.h: Accept fromleaf parameter. |
| * c-exp.y (yyerror): Pass error message if given. |
| * configure.in: Add rs6000 host and target. |
| * inflow.c (new_tty): O_NOCTTY kludge for RS/6000. |
| * symfile.h (entry_point): Add. |
| |
| Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com) |
| |
| * buildsym.c: New file. Breaks out symbol-table-building routines |
| from dbxread.c, so they can be shared with xcoffread.c. |
| * buildsym.h: New file. Declarations for buildsym.c users. |
| * dbxread.c: Remove large chunks into buildsym.c. |
| * Makefile.in: Add buildsym.c and buildsym.h. |
| |
| * symfile.c (syms_from_bfd): New routine. |
| (add_symbol_file): Call it to do the real work. |
| (syms_from_bfd): Initialize entry_point before calling symfile_init. |
| * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c: |
| Avoid declaring or setting entry_point (symfile.h & symfile.c cope). |
| |
| Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com) |
| |
| * cplus-dem.c (cplus-demangle): added support for templates, static |
| data, and the new (correct) mangling for destructors. |
| |
| * dwarfread.c: (dwarfwarn): created a varargs version of |
| dwarfwarn, for non __STDC__ compilers. |
| |
| * c-exp.y: (yylex): added match for "template" token. |
| (typebase): added TEMPLATE name '<' type '>' clause, for explicit |
| specification of template types. |
| |
| * symtab.c: (lookup_template_type): new function for finding |
| templates in symbol table. |
| (type_name_no_tag): changed to explicitly check for s/u/e at the |
| beginning of the symbol - if it is a template, none of these will |
| be there (but the name will still contain spaces.) |
| |
| Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com) |
| |
| Various fixes to improve g++ debugging. |
| * symtab.h: Add is_const and is_volatile flags for each method. |
| These are bit fields - take their space from voffset, |
| which shrinks to 30 bits. Since voffset is now a bitfield, |
| make it unsigned for portability. This changes its interpretation |
| slightly: Static methods now have voffset 1 instead of -1, |
| and virtual offsets start at 2, not 1. |
| * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name, |
| since it now returns an entire magled method name, not just |
| the type part. This avoids some duplication. |
| It also allows us to correctly mangle const and volatile |
| methods (using the new is_const and is_volatile bit fields |
| mentioned above). |
| * valprint.c (type_print_base), values.c (check_stub_method): |
| Simplify by using new gdb_mangle_name. |
| * values.c (value_headof): Fix to correctly handle single |
| inheritance (actually two fixes, either of which suffices). |
| * dbxread.c (read_struct_type): Handle const and volatile |
| method specifiers. |
| * dbxread.c (read_struct_type): Yet one more place where |
| we must handle '\\' continuations. |
| * valprint.c (vtbl_ptr_name): Add final '\0'. |
| |
| Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com) |
| |
| * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of |
| short return values for sparc and 68k. Patch from Paul Eggert. |
| |
| * coffread.c, coredep.c, i386-xdep.c: install patches for |
| SysV/386 3.2 from Mauro DePalma. |
| |
| Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com) |
| |
| * core.c (core_file_info), exec.c (exec_file_info): Print file |
| type. Use printf_filtered. |
| |
| * valops.c (value_fetch_lazy): Avoid 0-length fetches. |
| |
| Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com) |
| |
| * dwarfread.c: Add casts to remove compiler warnings. |
| |
| * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h, |
| tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h, |
| tm-sun3.h: Remove locally duplicated code for calling functions |
| in the inferior. The only differences were in the specific trap |
| vectors used and whether or not an fpu was present. These are |
| now handled by appropriate definitions of BPT_VECTOR and |
| HAVE_68881 respectively. Other minor obvious cleanups. |
| |
| * valops.c: Correct a minor misspelling. |
| |
| * utils.c: Remove local BSD/USG hacks that are now in libiberty. |
| |
| * dwarfread.c: Remove prototype for dwarfwarn. Does not work |
| with <varargs.h>. |
| |
| Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com) |
| |
| * stack.c (frame_command): Always print. Use new |
| frame_select_command to select a frame without printing. |
| |
| * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable. |
| |
| Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com) |
| |
| * dwarfread.c: New file for DWARF debugging format support. |
| |
| * elfread.c: New file for ELF object file format support. |
| |
| * procfs.c: New file for SVR4 /proc (process file system) support. |
| |
| * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for |
| Amiga UNIX support. |
| |
| * xm-svr4.h, tm-svr4.h: New files for SVR4 support. |
| |
| * xm-m68k.h: New file for host machines with m68k cpu. |
| |
| * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR. |
| Add elfread.o and dwarfread.o to OBS. |
| |
| * symfile.h: Add "elf" to list of supported formats in comment. |
| |
| * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin |
| types to gdb, builtin_type_long_double, builtin_type_complex, and |
| builtin_type_double_complex. Add and use new TARGET_SHORT_BIT, |
| TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT, |
| TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and |
| TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated |
| types on the target machine (ala the existing TARGET_LONG_LONG_BIT). |
| |
| * infrun.c: When using SVR4 /proc interface instead of ptrace(), |
| call proc_set_exec_trap() to setup child to stop at first instruction. |
| |
| * inftarg.c: When using SVR4 /proc interface, call proc_wait() |
| rather than wait(). |
| |
| * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(), |
| supply_fpregset(), and fill_fpregset(), which are machine |
| dependent support routines for SVR4 /proc interface. |
| |
| * utils.c: Add warning_setup() and warning(). Warning() behaves |
| the same as error() except that it returns normally rather than |
| jumping back to command level. Modules that don't want to call |
| warning() for some reason, but want to produce their own warnings, |
| can call warning_setup() to ensure compatibility with the way |
| warning() and error() deal with the terminal. |
| |
| * symtab.c: Make internal errors produce more useful messages. |
| |
| * tm-68k.h: Move code that is duplicated in almost every single |
| m68k based machine's configuration files to this common file. |
| Duplications in the configuration files still need to be removed |
| (FIXME). |
| |
| * infrun.c (child_create_inferior): System V versions must call |
| setpgrp() with no arguments, to comply with prototyping typically |
| in <unistd.h>. |
| |
| * munch: Add support for SVR4 style nm output. |
| |
| * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object |
| file specific fields from the partial symbol table structure and |
| replace them with a pointer to private data for each different |
| flavor of object file reader to initialize appropriately. |
| |
| Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com) |
| |
| * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c |
| and previous. |
| |
| * mipsread.c (fixup_undef_type): New function. If a struct / |
| union / enum is defined in a header file but nowhere else used, |
| (by typedefing, pointer referencing or declaration) the mipsread code |
| builds the complete tree for the structure but leaves its code as |
| TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is. |
| Guess its type based on the details of the members. |
| |
| Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com) |
| |
| * infrun.c (wait_for_inferior): Check return value from |
| find_pc_line. |
| |
| Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com) |
| |
| * infrun.c (wait_for_inferior): fix stepi/nexti that was broken |
| by my last edit to this routine. |
| |
| Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com) |
| |
| * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging. |
| FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap |
| the values before putting them into the dummy code. (From Peter |
| Schauer) |
| |
| Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com) |
| |
| * configure.in: added ebmon target. |
| |
| Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com) |
| |
| GDB-4.2 release! |
| |
| * Makefile.in: Roll VERSION to 4.2. |
| * README, TODO, WHATS.NEW: Update. |
| |
| * core.c (core_open): Improve error message for bad file. |
| Pass .reg virtual memory address to fetch_core_registers to help |
| it find the registers in the core-file header. |
| * coredep.c (fetch_core_registers): Take new argument, use it, |
| and pass it to register_addr to locate the block of registers. |
| * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit. |
| |
| * dbxread.c (read_dbx_symtab, process_one_symbol): Handle |
| Sequent N_FN_SEQ like everybody else's N_FN. |
| |
| * main.c: Circumvent SCO cc bug with #if !!defined(USG). |
| * tm-i386v.h: #endif guck. |
| * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge. |
| * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath. |
| * xconfig/tahoe: Add REGEX, which seems to be missing. |
| |
| * coredep.c: Add <sys/types.h> for SCOnix. |
| * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file. |
| * printcmd.c (print_formatted): Flush output before disassembly. |
| |
| Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com) |
| |
| * doc/refcard.tex (sec "Working Files"): consistent metavars and |
| other improvements, due to comments by François Pinard |

| |
| * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move |
| REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer. |
| |
| * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd. |
| |
| * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add |
| generic routines for calling inferior functions. |
| |
| * blockframe.c (inside_main_scope, inside_entry_scope): New. |
| |
| * copying.awk: Filter formfeeds out of copying & warrantee. |
| Make them available as `show copying' and `show warrantee' also. |

| |
| Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com) |
| |
| * mach386-xdep.c: Even when cross-compiling, leave in the |
| core-file reading code. |

| |
| Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com) |
| |
| * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1. |
| This avoids coredumps under `set print object on' in value_headof |
| (called erroneously by value_from_vtable_info) for `p &struct' |
| or `p *struct'. From Peter Schauer. |
| |
| Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com) |
| |
| * Makefile.in: Roll version to 4.1.2. |
| * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry |
| size from BFD (but, FIXME, we don't yet read external nlists's and |
| convert them to internal nlists's before handling them -- we still |
| assume they have the same size and alignment.) Use SET_NAMESTRING |
| everywhere useful. |
| * exec.c (exec_file_command): Move dead coff-encapsulation code |
| to BFD. |
| * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>. |
| |
| Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com) |
| |
| * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port. |
| * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files. |

| |
| More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>: |
| * mips-xdep.c (store_inferior_registers): Don't try to |
| write the (pseudo) FP. |
| * mipsread.c (parse_partial_symbols): Improved algorithm for |
| setting pst->texthigh. |
| |
| Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com) |
| |
| * doc/Makefile: make TEXINPUTS include . everywhere |
| |
| Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com) |
| |
| * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove |
| vestiges of typevectors, which were for symsegs and are no longer |
| used. (From a question by Eliot Dresselhaus |
| <dresselh@RFT30.nas.nasa.gov>). |
| |
| Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com) |
| |
| * dbxread.c, coffread.c: static-ize functions that were |
| gratuitiously external. (From Fred Fish.) |
| |
| * c-exp.y: sym->class to SYMBOL_CLASS (sym). |
| |
| * dbxread.c (dbx_lookup_type): Keep doubling size of typevector |
| until it is large enough. |
| |
| * dbxread.c (read_type): Handle error case slightly better. |
| Make complaint message not C++-specific. |
| |
| Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com) |
| |
| * infrun.c (wait_for_inferior): Fix step/next so that you only |
| stop at the beginning of a new line. This fixes various problems |
| with for loops, nested if-else's and switch statements. |
| |
| Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com) |
| |
| * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors |
| between symtabs and psymtabs become ordinary error()s. |
| |
| * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr |
| properly, making "end pc" correct in shared lib psymtabs. |
| (From Guy Harris <guy@auspex.com>.) |
| |
| Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com) |
| |
| * dbxread.c: Enable, but soften, const_vol_complaint. |
| (read_dbx_symtab): N_STSYM and N_LCSYM define static vars. |
| Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab |
| should be file-scope, not global. |
| (read_struct_type): Remove ancient multiple-inheritance warning. |
| (read_range_type): Check base type, complain & patch if undefined. |
| * stack.c (frame_info): Demangle the function name in `info stack'. |
| (From Peter Schauer) |
| |
| Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com) |
| |
| * eval.c (evaluate_subexp_for_address): Don't use |
| TYPE_POINTER_TYPE directly (it might be zero if this type has |
| never had a pointer created before); use lookup_pointer_type. |
| * symtab.c (lookup_method_type): Arguments were swapped in all |
| callers, so fix it here. I'm amazed this worked at all! |
| |
| Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com) |
| |
| * c-exp.y, m2-exp.y: Define more yysymbols that happen to be |
| "bss" rather than "data" symbols, but which still conflict. |
| * m2-exp.y: Lint. |
| |
| * coffread.c (coff_symfile_read): Use xmalloc, not malloc. |
| * core.c (core_files_info): Shorten output. |
| * exec.c (exec_files_info): Ditto. |
| (build_section_table): Ignore zero-length sections. |
| * language.c, printcmd.c: Lint. |
| * language.h (get_frame_language): Declare. |
| * saber.suppress: update. |
| * stack.c (find_relative_frame): Remove complex code that was |
| #if 0'd, stick with simple code. Lint. |

| * symfile.c (add_symbol_file_command): Add "?" to question. |
| * utils.c (parse_escape): Avoid \a due to bdead compilers. |
| * value.h: Declare typedef_print. |
| |
| * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less |
| kludgey. |
| |
| * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func. |
| (Reported by Mark Peek <mark@imagen.com>.) |
| |
| * solib.c (solib_map_sections): Relocate all sections, even |
| though only the text section's size is tracked. Mark ld_text |
| for eventual elimination as we generalize to N sections. |
| |
| * infrun.c (wait_for_inferior): Don't check if the PC is in a |
| call_dummy if we were stopped by a random signal that is being |
| passed to the program. This produced wierd results when calling |
| functions in the inferior and signals (e.g. SIGALRM) were in use. |
| |
| Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com) |
| |
| * infrun.c (IN_SIGTRAMP): Not parenthesized properly. |

| easier into README. |
| * configure.in: Rename rtpc CPU to romp to match config.sub. |
| * README, WHATS.NEW, TODO: Update for gdb-4.1. |
| |
| Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com) |
| |
| * doc/gdb.texinfo: Updates from ChangeLog. set/show write, |
| autoloading shared libs, copyright etc on GDB startup, clean up $_ |
| and $__ index refs, set/show listsize and related updates to list |
| cmd. New host/target configs. |
| |
| Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com) |
| |
| * doc/Makefile: generate aux version-no file doc/gdbVN.m4 |
| from main Makefile.in version definition |
| doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current |
| GDB version no refs |
| Makefile.in (setup-to-dist): generate doc/gdbVN.m4 |
| |
| * doc/gdb.texinfo: merge new language-switching and lang-specific |
| doc by Andrew Beers |
| |
| Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com) |
| |
| * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI |
| compilers (which may lack stddef.h). |
| |
| Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com) |
| |
| * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and |
| N_WARNING are the same except for the N_EXT bit, so just use their |
| values alone, rather than OR-ing them with N_EXT. |
| |
| Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com) |
| |
| * mipsread.c (parse_lines): Deal with negative extended line |
| offsets correctly. |
| |
| * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid |
| global symbol conflicts. |
| |
| Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com) |
| |
| * .gdbinit: Move 'set complaints' to top, so it runs even in |
| case we aren't debugging GDB. |
| * language.c (_initialize_language): Fix type check and range |
| check documentation strings. |
| * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so |
| language.c can use it. (Though language.c should really not be |
| handling warnings/errors the way it does, FIXME.) |
| * symtab.c (lookup_primitive_type): const lint. |
| |
| Bugfix from Peter Schauer: |
| * source.c (lines_to_list): Make signed, to avoid comparison |
| going unsigned and complaining that -3 is too high for 21 lines. |
| * stack.c (lines_to_list): Ditto. |
| |
| Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com) |
| |
| * Makefile.in (HFILES): Add minimon.h. |
| (VERSION): Roll version number to 4.0.95. |
| (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z): |
| New rules for building distributions. Normal distribution |
| is built by doing `make -f Makefile.in gdb.tar.Z' in the directory |
| one level up from here; it calls make-proto-gdb.dir to build a |
| directory `proto-gdb' which is an image of the release. The old |
| `gdb.tar.Z' rule still works too. |
| * config.sub, configure: Roll in latest from .. |
| |
| Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com) |
| |
| * doc/gdbint.texinfo: Reorder contents; reorganize new-host, |
| new-target, and new-config chapters; fix minor typos; come closer |
| to usual GNU markup conventions for @file @samp @code @var. |
| |
| Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com) |
| |
| Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>: |
| * mipsread.c (parse_partial_symbols): Enter the name of all |
| structs/unions... into the psymtab so we can access them if the |
| symtab is not read in. |
| * mips-tdep.c: Remove some unneeded #includes. |
| * xconfig/dec3100: Add HAVE_STRSTR. |
| |
| Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com) |
| |
| * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o. |
| * c-exp.y, m2-exp.y: Lint. |
| * m2-exp.y: Avoid using yytname[] which is a Bison-ism. |
| * valprint.c (val_print_fields): Check for stub type. |
| * mipsread.c (_initialize_mipsread): Avoid using |
| builtin_type_void at initialize time. |
| (mipscoff_symfile_read): use it now. |
| |
| Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com) |

| |
| Add Andrew Beers' changes for Modula-2 support. His ChangeLog |
| entries are enclosed herein. Not all of these changes |
| have been merged into the master GDB sources -- check the |
| ChangeLog above here for the merge log. |
| |
| Mon Jun 3 17:05:45 EDT 1991 |
| |
| m2-exp.y Created. Tested outside of GDB for a few days. Proper |
| operators were added, C specific operators and tokens |
| removed. yylex() revamped to some extent. Still things |
| missing from the grammar, such as sets. |
| Tested for two weeks in GDB v3.5. |
| |
| Tue Jun 11 17:23:48 EDT 1991 |
| |
| m2-exp.y Added boolean constants TRUE and FALSE to the grammar |
| so they are built-in. Sort of a hack. |
| |
| Fri Jun 14 12:53:51 EDT 1991 |
| |
| m2-exp.y Added range checking for numeric constants. Any numeric |
| constant is assumed to be of builtin type INTEGER unless: |
| (1) it is octal or hexadecimal, in which case it is a |
| CARDINAL; (2) it is too big to fit into an INTEGER, in |
| which case it is a CARDINAL. |
| eval.c Added simple range checking for +, -, and * on integers. |
| Doesn't work very well for *, since 6 * 1,000,000,000 = |
| 1,705,032,704, which fails the simple test of result >= |
| first_operand, no matter in what order the operands are. |
| |
| Tue Jun 18 14:11:30 EDT 1991 |
| |
| Broke the parser into parts, one containing the C grammar and the other |
| containing code to be shared by all of the grammars. |
| |
| The following files no longer exist: |
| |
| expread.y |
| expread.tab.c |
| |
| The following files were added: |
| |
| c-exp.y (The C grammar) |
| m2-exp.y (The Modula-2 grammar) |
| parser-code.c (Code that is shared by the above grammar) |
| parser-code.h |
| parser-defs.h |
| |
| Makefile.dist Changed to reflect the above dependencies. NOTE: It is |
| now necessary to use the Bison compiler compiler, since it |
| will generate function/variable prefixes other than yy. |
| |
| Tue Jun 18 16:47:49 EDT 1991 |
| |
| symtab.[ch] Added the external variable working_lang, than holds the |
| value of the current working language. |
| Added the ennumerated type language_mode, with the values |
| language_auto and language_manual, the former meaning that |
| GDB sets working_lang as needed, and the latter meaning |
| that the value of working_lang is totally under user |
| control. |
| symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL, |
| REAL, BOOLEAN and CHAR. Also added the type codes |
| TYPE_CODE_BOOL and TYPE_CODE_CHAR. |
| utils.c Added set_language_command and show_language_command to |
| implement the GDB support commands "set language" and |
| "show language". |
| expression.h A number of identifiers were added to the type exp_opcode |
| to facilitate Modula-2 builtin functions, integer |
| division, and array indexing. |
| |
| Wed Jun 19 13:25:58 EDT 1991 |
| |
| language.h Added the macro STRICT_TYPE, which evaluates to non-zero |
| if the language specified by working_lang requires the use |
| of strict typing of expressions. Eventually, even this |
| will be able to be changed by the user. |
| Added the macro RANGE_CHECK, which evaluates to non-zero |
| if the language specified by working_lang requires the |
| checking of a value against the domain of its type. |
| Eventually, even this will be able to be changed by the |
| user. |
| language.[ch] Predicates involving types (simple_type, ordered_type, |
| same_type, integral_type, numeric_type, character_type, |
| boolean_type, float_type) are added. These predicates are |
| based on the current value of working_lang, and are handy |
| in type-checking. |
| |
| Wed Jun 19 15:39:34 EDT 1991 |
| |
| eval.c Added the function type_array_rank which computes the rank |
| of an array type. |
| valarith.c Added the funtion value_bool, which when given a integer |
| value.h value (ie. struct value *) as an argument, it returns a |
| boolean value (ie. struct value *) true if that integer |
| is non-zero, and a boolean value false otherwise. |
| valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values |
| will print out properly. |
| |
| Wed Jun 19 16:36:34 EDT 1991 |
| |
| valops.c Added the function value_capitalize, which returns it |
| value.h argument capitalized if its argument is a lowercase |
| letter, or the argument unchanged if its argument is not a |
| letter. |
| valarith.c Added the function range_check_p, which returns non-zero |
| value.h if its value argument is between the integral bounds upper |
| and lower. |
| Added the function range_check_enum_p, which makes sure |
| that its value argument is a valid member of the domain of |
| its type argument. |
| Added the function range_check_range_p, which makes sure |
| its value argument lies between the upper and lower bounds |
| of its type argument, which must be a ranged type. |
| Added the function check_array_index, which range and type |
| checks an index of an array. |
| Added the function value_multi_subscript, which computes |
| array[idx1,idx2...idxN], given a value array and an array |
| of values representing indicies. |
| values.c Changed value_from_long to work with TYPE_CODE_CHAR and |
| unpack_long to work with TYPE_CODE_BOOL and |
| TYPE_CODE_CHAR. |
| |
| Wed Jun 19 18:04:08 EDT 1991 |
| |
| symtab.c Stored pervasive types in a structure and make |
| lookup_pervasive_type() a lookup function that was based |
| on working_lang. If lookup_pervasive_type() returned |
| non-zero, then that value was returned (a fix, since |
| before it simply wouldn't return the pervasive type.) |
| language.h Added the macro CAST_IS_CONVERSION, which evaluates to |
| non-zero if the language specified by working_lang means |
| "conversion" when it says "cast". |
| valops.c Added the function value_real_cast(), which performs a |
| value.h *cast*, not a *conversion*, which is what value_cast() |
| does when it can. In particular, |
| value_cast(<float_type>,4) = 4.0, while |
| value_real_cast(<float_type>,4) = some mess. |
| eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR, |
| parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL. |
| expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX |
| and MIN on integral types. *NOTE*: These are currently |
| hardcoded to work only if there are 8 bits per storage |
| unit. FIXME. |
| eval.c Made logical functions call value_bool to return a |
| properly typed boolean value, based on working_lang. |
| |
| Thu Jun 20 11:55:27 EDT 1991 |
| |
| valprint.c Types now print out in a Modula-2 fashion. This works for |
| the cases when the type is printed out step-by-step, that |
| is, it doesn't work when the name of a structured type |
| (which includes the keyword "struct", etc.) is simply |
| displayed. |
| FIXME: Perhaps this is bad. Parts of it seem to kludgey, |
| since type specifications in C and Modula-2 are very |
| different. The C printing of a type is very recursive, |
| whereas in Modula-2 it is generally very simple. C has |
| type prefixes and suffixes, which have no real analogue in |
| Modula-2. Maybe type_print() should call a language |
| specific type printer. This is also advantageous if we |
| compile GDB to exclude some of the languages. We'll just |
| leave those functions out. |
| |
| Thu Jun 20 16:57:10 EDT 1991 |
| |
| dbxread.c When reading the complete symbol table in (via |
| psymtab_to_symtab()), the number and types of function |
| arguments are added to a function type. define_symbol() |
| calls add_param_to_type() to accomplish this. |
| Assumption: when we come across a function definition |
| (N_FUN symbol with an 'f' or 'F' in the name), its |
| arguments will appear before another function definition. |
| When a function is found, a pointer to its type is placed |
| in the global in_function_type. Changes that |
| add_param_to_type() makes are to this global. |
| valprint.c The type of a function now includes (for Modula-2) the |
| types of its parameters. |
| eval.c Type checking and a check for the proper number of |
| arguments is now done for function calls. Not sure of the |
| impact this has on C++ member function yet. |
| |
| Thu Jun 20 19:58:48 EDT 1991 |
| |
| valprint.c Rewrote the type printer. Broke it into two language |
| specific parts, adding the functions type_print_m2() and |
| type_print_m2_1(). |
| An unfortunate consequence is this: if you debugging a C |
| program in Modula-2 mode (why?), info types does not work |
| well with regular expressions, since the types are printed |
| out in Modula-2 terminology, but stored in C terminology. |
| language.[ch] Added the functions new_type_last(), type_keyword(), and |
| type_sep() to aid in the printing of typedefs. |
| symtab.c Made the printing of typedefs as language independent as |
| possible through calls to new_type_last(), type_keyword(), |
| and type_sep(). |
| |
| Fri Jun 21 11:50:26 EDT 1991 |
| |
| dbxread.c Check all incoming ennumerated types. If it looks like |
| Modula-2's BOOLEAN type, then change the type_code of the |
| type to TYPE_CODE_BOOL so we can process it as a boolean |
| variable. |
| valprint.c Replaced some of the 0x%x with calls to sprintf and |
| hexformat() in val_print(). |
| language.[ch] Added the function hex_to_string(), which converts its |
| integral argument to a hexadecimal number (format is |
| language based) and returns the result as a string. |
| |
| Mon Jun 24 12:25:07 EDT 1991 |
| |
| valprint.c Some functions call type_print_1() directly, instead of |
| value.h using type_print(), so they can specify where (column) to |
| print things. Since type_print() takes care of language |
| dependence, that needs to be called first. Added a |
| parameter depth to type_print() (so it is now like |
| type_print_1). Changed type_print to type_print_at, and |
| made type_print a macro that passes a depth argument of |
| zero. |
| symmisc.c Changed all calls to type_print_1 to calls to |
| type_print_at. |
| Makefile.dist Made it possible to build GDB for a specific set of |
| depend languages. Do this by passing a definition for the macro |
| LANGS to make. LANGS should be a string containing a |
| space-separated list of language names (ie. LANGS="c m2"). |
| The default is to build all languages. Note that grammar |
| files must follow the naming convention of <lang>-exp.y. |
| gdb.lang This holds the current value of the LANGS macro. It is |
| examined every time make is called, and is updated if |
| necessary. |
| eval.c Added #ifdef _LANG_<lang> to these files. |
| expread.c Still need to add them to dbxread.c and coffread.c. |
| main.c |
| source.c |
| symtab.c |
| utils.c |
| valarith.c |
| valprint.c |
| |
| Mon Jun 24 16:33:11 EDT 1991 |
| |
| language.[ch] Added the functions hexformat_pre() and |
| hex_to_string_pre(), which take a prefix argument to |
| include in the format string. Thus, hexformat_pre("08") will |
| return "0x08x" (if the working language is language_c). |
| Made hexformat() and hex_to_string() calls to the above |
| with "" as the prefix argument. |
| |
| am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c, |
| dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c, |
| infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c, |
| mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c, |
| pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c, |
| stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c, |
| valprint.c, vax-pinsn.c |
| |
| Changed all occurences of 0x%[0-9]*l*x in printf format strings to |
| calls to hexformat() and hex_to_string(). Format strings without |
| the leading "0x" were ignored. |
| |
| depend Updated to take the above into account. |
| |
| |
| Tue Jun 25 15:27:18 EDT 1991 |
| |
| symtab.h Added the types range_mode_t, range_check_t, type_mode_t, |
| and type_check_t to keep track of the current state of |
| range and type checking. |
| main.c Added the variables range_mode, range_check, type_mode, |
| and type_check to record the current state of range and |
| type checking. Added initialization code to main(). |
| language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine |
| the above variables. |
| |
| |
| Tue Jun 25 17:57:08 EDT 1991 |
| |
| dbxread.c process_one_symbol() updates the variable (enum language) |
| source_lang based on the extension of the filename |
| contained in the N_SO sybmol that started this symtab. |
| When end_symtab() is called, the value of source_lang is |
| put into the language field. |
| stack.c select_frame() sets working_lang (and possibly type_check |
| and range_check) to the language field of the symtab |
| associated with the frame that is selected if working_mode |
| is language_auto. If working_mode is language_manual, a |
| warning is printed and working_lang is not set. |
| language.c Added the function set_type_range(), which sets the value of |
| type_check and range_check (if their modes call for |
| automatic setting) based on the current value of |
| working_lang. A non-zero argument will cause the current |
| settings to be output. |
| |
| |
| Wed Jun 26 14:51:40 EDT 1991 |
| |
| eval.c Added range checks on assignment. |
| m2-exp.y Added the grammar for sets to the language. Currently, |
| these do not do anything except print an error message. |
| |
| Wed Jun 26 17:01:04 EDT 1991 |
| |
| m2-exp.y Added the ability for parse_number() to parse negative |
| numbers. A global flag is set upon encountering a unary |
| minus. This was done to make, for example, 1 parse as a |
| CARDINAL, and not as an integer, per Wirth's examples in |
| Programming in Modula-2 ed.4. |
| valprint.c Added support for "set radix 2" by then setting |
| output_format to 't'. |
| eval.c Implemented range checking on subrange types. Added calls |
| to range_check_range_p for BINOP_ASSIGN and BINOP_VAL. |
| Implemented MIN and MAX for ennumerated types. The |
| minimum value of an ennumerated type is defined by Wirth |
| as the first identifier, and the maximum as the last. |
| m2-exp.y Made octal numbers ending with "B" be characters and those |
| ending with "C" be numbers, per Wirth's book. (p. 34) |
| |
| Thu Jun 27 14:11:52 EDT 1991 |
| |
| stack.c select_frame() now only sets working_lang, it does not |
| notify the user. If working_mode is language_manual, then |
| a warning is issued once. |
| main.c At the end of each call to execute_command(), working_lang |
| is checked against the local static (enum language) |
| current. If they differ and working_mode is |
| language_auto, the new settings of language, type and |
| range checking are printed out. |
| stack.c Modified frame_info() to include the language of the |
| current frame in the output of "info frame". |
| language.[ch] Added the function language_str() which returns the name |
| of the current language. |
| |
| Fri Jun 28 15:33:14 EDT 1991 |
| |
| m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to |
| the language. INCL and DECL currently cause an error, |
| since sets are not implemented yet. INC and DEC are |
| implemented as PREINCREMENT/PREDECREMENT with one |
| argument, and as ASSIGN_MODIFY with two arguments. |
| eval.c Added type checking to the above cases. |
| value.h Added not_lval_constant to the lval_type ennumerated type. |
| not_lval_constant means that the value is a constant |
| value; that is 3 or 'a' or TRUE, not as in a constant |
| identifier. This is used to help coerce numbers such as 3 |
| to either signed or unsigned numbers. |
| valops.c Added the function value_coerce_constants() which coerces |
| constant integers as following: if one is a constant and |
| the other is not, the constant's type is set to the type |
| of the other argument. If both are constants and one is |
| signed, the other is converted to a signed constant. |
| |
| Sat Jun 29 17:26:29 EDT 1991 |
| |
| valarith.c Added a better range checker. It now checks range |
| (successfully) on integral operations [+-] (signed and |
| unsigned) for any C sized type. Still does not work well |
| for multiplication.) |
| int_in_size() returns an integer that is coerced to fit into |
| specified number of bytes. |
| |
| Mon Jul 1 13:04:14 EDT 1991 |
| |
| language.[ch] Added the function binop_result_type(), which returns the |
| builtin (struct type *) type that would be the result of a |
| binop on the two values V1 and V2. |
| |
| Wed Jul 3 19:22:53 EDT 1991 |
| |
| source.c Extended source_info() to include the source language in |
| the output from "info source". |
| |
| Fri Jul 5 13:48:52 EDT 1991 |
| |
| utils.c Moved the support functions for the GDB set/show commands |
| dealing with language into language.c. |
| language.c Added the function language_info(), which displays info |
| about the current working language, type and range check |
| settings. Called via the GDB command "info language". |
| Added an initialization routine _initialize_language(), |
| that sets defaults for the language, type and range |
| variables and sets up the new GDB commands. |
| main.c Language setup moved to language.c. |
| depend Rebuilt. |
| |
| Mon Jul 8 10:10:22 EDT 1991 |
| |
| valarith.c Debugged the range checker for arithmetic. Still does not |
| work for multiplication very well. |
| |
| Mon Jul 8 12:40:37 EDT 1991 |
| |
| language.[ch] Added the function value_true() which returns non-zero if |
| its argument represents a boolean true value. |
| breakpoint.c Changed breakpoint_cond_eval() to call value_true() to |
| check the truth of an expression. |
| |
| Thu Jul 11 12:51:34 EDT 1991 |
| |
| language.[ch] Added the predicate structured_type(), which returns |
| non-zero if the argument is a structured type. |
| Added the predicate pointer_type(), which returns non-zero |
| if the argument is a pointer type. |
| eval.c Added the ability to do addition and substraction on |
| pointers and integers. This case simply bypasses the |
| type checker. |
| |
| Thu Jul 11 14:41:42 EDT 1991 |
| |
| include/stab.def |
| Added the symbol N_DEFD (0x4a) which is a definition |
| module dependency that is used by the GNU Modula-2 |
| compiler and the linker. It is not important to GDB, |
| except that [dbx|coff|mips]read.c should ignore these |
| symbols. |
| |
| Fri Jul 12 16:07:00 EDT 1991 |
| |
| valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) > |
| 0 in val_print(). Also added statements to the else part |
| to coerce type (argument to val_print) to a pointer type |
| if it is an "array of unspecified length". |
| valops.c Added the function value_m2_string(), which returns a |
| (value) value which is a constant string, whose type is |
| (ARRAY [0..n] OF CHAR). The length field of the type |
| structure is set to zero, so it will be interpreted as an |
| "array of unspecified length". |
| stack.c Moved the language/frame mismatch check to |
| main.c:execute_command(). |
| main.c The working language is recorded each time |
| execute_command() is executed. If working lang has |
| changed during its execution, then the new |
| language/type/range info is printed out for the user. If |
| the working language does not match the language of the |
| frame, a warning is issued. |
| |
| Sat Jul 13 16:16:39 EDT 1991 |
| |
| eval.c Moved all the type-checking stuff for operators to |
| language.[ch] language.c. This is so we can keep language-specific |
| stuff (like for what type operators are defined) in |
| language.c. |
| language.[ch] Added the function binop_type_check(), which checks to see |
| if its two (value) arguments are type-compatible with its |
| opcode argument. The opcode should represent an operation |
| involving an operator. Also added the macro function |
| unop_type_check, which calls binop_type_check with a |
| NULL second argument. |
| expprint.c Added Modula-2 operators to the op_print_tab, so info |
| expression.h break works correctly. Also added "op_string", which |
| returns the string corresponding to the (enum exp_opcode) |
| opcode that is its argument. |
| |
| |
| Sat Jul 13 18:26:18 EDT 1991 |
| |
| coffread.c Added code to record the type of function arguments with |
| each paricular function. Code is very similar to that |
| added to dbxread.c. |
| dbxread.c Moved add_param_to_type() to symtab.c |
| symtab.[ch] Added function add_param_to_type() from dbxread.c |
| |
| *** NOTE: The above additions have not been tested. |
| |
| Mon Jul 15 12:50:47 EDT 1991 |
| |
| langauge.[ch] Added the functions type_error and range_error, which work |
| like error() except if the type/range mode is set to |
| *_mode_warn, then they do not do a return_to_top_level(), |
| but merely print a warning. |
| Also changed [set|show]_[type|range]_command() to support |
| the new "warn" feature. |
| |
| Thu Jul 18 17:50:54 EDT 1991 |
| |
| mipsread.c Added code to record the type of function arguments with |
| each particular function. Code is very similar to that |
| added to dbxread.c. |
| |
| *** NOTE: The above additions have not been tested. |
| |
| Fri Jul 19 11:19:10 EDT 1991 |
| |
| defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and |
| UMIN_OF_SIZE, which when given a size of a numeric type, |
| return the maximum and minimum value it can hold. UMAX... |
| and UMIN... return the result for unsigned types. |
| symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on |
| struct types. They call above macros. |
| dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to |
| avoid a name conlict with the above. |
| c-exp.y Added range checking on numeric constants in |
| parse_number() for completeness. |
| valarith.c Made binop_user_defined_p() and unop_user_defined_p() |
| return 0 if working_lang is not language_c. |
| |
| Thu Aug 8 14:17:22 EDT 1991 |
| |
| main.c |
| printcmd.c |
| breakpoint.c Documentation strings of some commands changed to |
| eliminate the references to the C language where |
| appropriate. |
| |
| Tue Aug 13 15:48:03 EDT 1991 |
| |
| m2-exp.y Added qualified identifiers to the grammar. The semantics |
| are slightly different from those of the GDB operator :: |
| c-exp.y |
| m2-exp.y Added a rule to each grammar of the form: start ::= exp | |
| type_exp, where type_exp is any valid type expression. |
| expression.h |
| eval.c Added the opcode OP_TYPE, and an error case in eval.c. |
| printcmd.c Modified ptype_command() so it actually parses the input |
| (necessary for type expressions with scope qualifiers). |
| Added the function ptype_eval() which expects an |
| expression composed of one OP_TYPE element. |
| *.[ch] Replaced all occurences of parse_c_expression with |
| parse_expression |
| *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1 |

| |
| Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com) |
| |
| Small fixes from Peter Schauer: |
| |
| * infrun.c (child_attach): Lint. |
| * solib.c (find_solib): Handle shared libs version 2. |
| |
| Small fixes from David Wood: |
| |
| * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo. |
| |
| Small fixes: |
| |
| * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from |
| John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>. |
| |
| * utils.c (wrap_here): Avoid wrap action of fputs_filtered if |
| chars_per_line is at maximum (user typed `set width 0'). Fix |
| from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>. |
| |
| Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com) |
| |
| * coredep.c: include ptrace.h where necessary. |
| * mipsread.c(parse_lines): fix unsigned char problem that was |
| messing up line numbers on SGI's and possibly other MIPS based |
| platforms. |
| * infrun.c (child_create_inferior): use better test to check |
| return val from setpgrp(). |
| * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these |
| for sgi/irix support. |
| |
| Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com) |
| |
| * mipsread.c (parse_symbol): Put non-static procedures |
| in the global block. |
| |
| Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com) |
| |
| Patch together `text_start' and `text_end' for 29K port. |
| |
| * exec.c (exec_command): If NEED_TEXT_START_END, define the |
| variables and set them based on the exec file. |
| * am29k-tdep.c: declare text_start. |
| * valops.c (call_function_by_hand): declare text_end. |
| |
| * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of |
| defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is |
| because machines that do this will also have to know to |
| set NEED_TEXT_START_END. Besides, it was a redundant way to |
| say the same thing. |
| * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate |
| CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and |
| NEED_TEXT_START_END. |
| |
| Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>: |
| |
| * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end. |
| Pass MUNCH_DEFINE to munch whenever we run it. |
| * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x |
| format string; use 0x%x instead. |
| * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM. |
| * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system. |
| * xm-rtbsd.h: New host support for RT/PC running BSD Unix. |
| * inflow.c: Handle `short' process group IDs. |
| * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER, |
| and check for ptrace errors. |
| * coffread.c (SDB_REG_TO_REGNUM): Define if not already. |
| (coff_symfile_init): Initialize text_bfd_scnum. |
| (read_coff_symtab): Use it to find the text [and absolute?] sections. |
| * ../config.sub: Add vendor nyu and os "sym[1-9]*". |
| * configure.in: Add hosts rtpc-*-* and a29k-*-*. |
| Merge target arm case with other "easy" cases. Add target |
| cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to |
| Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user |
| process). |
| * minimon.h, remote-adapt.c, remote-mm.c: Add. |
| * munch: Cope with RT/PC putting fns in data segment. |
| Restore ability to override `nm' by specifying MUNCH_NM. |
| * xconfig/rtbsd, xconfig/ultra3: New host systems. |
| * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm |
| and remote-adapt. Remove encapsulated coff #define's (the |
| support should go in BFD, and gdb shouldn't know or care). |
| * tconfig/a29k-kern: Same, but for remote kernel debugging. |
| * tconfig/ultra3: For debugging user processes on Ultra3/Sym1. |
| * tm-29k.h: Update BADMAG (though it should go away). |
| Allow the register definitions to be overridden in another |
| tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate |
| RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from |
| DUMMY_SAVE_GR96, for handling kernel calling conventions |
| that use GR64+ rather than GR96+. |
| * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for |
| remote debugging of Ultra3 kernel. Includes tm-29k.h and |
| overrides various things. |
| |
| * remote-mm.c (mm_attach, mm_wait): Handle attach like |
| child_attach does, making a clean stop in the newly attached |
| program. |
| * remote-eb.c: Lint. |
| |
| * coffread.c: Make coffread independent of any particular |
| variant of COFF. Avoid #include-ing any particular one except |
| internalcoff.h. BFD now passes key values for symbol reading |
| as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ, |
| and the symbol masks and shifts); use them. |
| Remove obsolete end_of_text_addr. |
| |
| * exec.c: Remove unused include files. |
| |
| Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * Makefile.in (documentation targets): Pass $(M4). |
| Bugfix from eggert@twinsun.com (Paul Eggert). |
| |
| * stack.c (down_silently_command): Check for stack existence. |
| |
| Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * Makefile.in (VERSION): Update to 4.0.3. |
| |
| Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * core.c (core_file_command): Print frame at coredump with |
| its level number, by calling print_stack_frame. |
| * frame.h: Add selected_frame_level, print_stack_frame. |
| * frame.h, stack.c: Remove print_sel_frame, print_selected_frame. |
| * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c: |
| Change print_sel_frame and print_selected_frame callers to |
| print_stack_frame. |
| |
| * dbxread.c (read_ofile_symtab): Avoid empty else clause. |
| * symfile.c (free_named_symtabs): Ditto. |
| * main.c (main): wrap_here needs an arg. |
| * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero. |
| (solib_add): Avoid noise. |
| (solib_create_inferior_hook): Lint. |
| (sharedlibrary_command): Move dont_repeat to here. |
| * utils.c (error): Call wrap_here to force buffered output. |
| |
| Small patches from Peter Schauer: |
| |
| * coffread.c (start_symtab): Free any existing line_vector before |
| malloc-ing new one. |
| (read_coff_symtab): Ditto for type_vector. |
| |
| * source.c (lines_to_list): New variable, replacing function. |
| (all uses): Use as variable. |
| (_initialize_source): Add 'set listsize' and 'show listsize'. |
| * utils.c (lines_to_list): Remove function. |
| * stack.c (print_frame_info): Use as variable. |
| * defs.h (lines_to_list): Remove declaration. |
| |
| Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * breakpoint.c (insert_breakpoints): Restore warning about |
| the program might be running in another process, but only for |
| systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT). |
| * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it. |
| |
| * utils.c (error): if error_pre_print is set, print the string |
| first. |
| * main.c (main, print_gnu_advertisement, print_gdb_version): |
| Reformat legalese so it always prints, but acts as an "I'm here" |
| message while symbols are being read. If any errors occur, |
| print a few newlines to set off the message and start it at the |
| left margin. Remove mention of "help" command, and don't yak |
| about symbol reading. |
| (catch_errors): Error string is now printed first in case of |
| error, not last. |
| * command.c (undef_cmd_error, lookup_cmd): On undefined command, |
| suggest the "help" command. |
| |
| * Makefile.in (VERSION): Set to 4.0.2. |
| |
| Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * .gdbinit: Remove useless "rr" command. Set complaints |
| to 1 for people debugging gdb. |
| |
| * breakpoint.c, remote-vx.c: Reword strings printed by |
| catch_errors callers. |
| |
| Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * WHATS.NEW: "history write -> history save". Doc "write on/off". |
| (Fix from kenc@viewlogic.com.) |
| |
| Fix some infrastructure to be able to cope with host and target |
| machines with different sized basic types (ints, ptrs, etc). |
| (Idea from pierre@la.tce.com (Pierre Willard).) |
| |
| * values.c (value_from_longest): Rename from value_from_long. |
| Handle pointer types as well as integers, so that targets with |
| different pointer sizes from the host can be accomodated. |
| * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c, |
| valarith.c, valops.c, valprint.c, value.h, values.c: Rename |
| uses of value_from_long to value_from_longest. |
| * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass |
| the correct pointer type to value_from_long{est}. |
| |
| * doc/gdb.texinfo ($_, $__): Describe types of these variables. |
| |
| * remote-vx.c: Remove obsolete code for calling functions via |
| vxworks kludge interface (it referenced value_from_long). |
| |
| * valops.c (value_string): Find malloc with lookup_misc_func, not |
| raw search. |
| |
| Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| Make writing to files work properly. (Fixes to BFD are also needed.) |
| |
| * core.c (core_open): Open file ourselves, read or r/w, depending on |
| write_files. Use bfd_fdopenr. |
| * gdbcore.h (write_files): New variable. |
| * exec.c (write_files): Define variable, add set&show for it. |
| (exec_file_command): Use write_files to open for read or r/write. |
| |
| Make shared library reading happen automatically. These changes |
| are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>. |
| |
| * inferior.h (stop_soon_quietly): Add to exported variables. |
| * infrun.c (child_create_inferior): call solib hook, if defined. |
| (child_attach): call solib hook, if defined. |
| * solib.c: Include inferior.h. Add from_tty to so_list as kludge. |
| (find_solib): Use lookup_misc_func rather than hand-rolled. |
| (symbol_add_stub): New stub for catch_errors. |
| (solib_add): Avoid output if !from_tty. Catch errors rather |
| than just calling symbol_file_add and bombing. |
| (solib_create_inferior_hook): Interface with the target process |
| to let it read and alloc shared libs, then figure out what it did. |
| |
| * core.c (validate_files): Fix typo, soften warning. |
| (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.) |
| |
| * utils.c (fputs_demangled): Avoid duplicate printing if |
| demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.) |
| |
| * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing. |
| (Fix from pierre@la.tce.com (Pierre Willard).) |
| |
| * main.c (catch_errors): Change argument to a char * from an int, |
| since a char * can point to a struct full of glop, but an int |
| is not guaranteed to be able to hold a pointer. |
| * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status, |
| breakpoint_re_set_one, breakpoint_re_set): Adapt. |
| * core.c (core_open, solib_add_stub): Adapt. |
| * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt. |
| |
| Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |

| |
| Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com) |
| |
| * doc/gdb.texinfo: minor rewordings, crossref to ptype from print, |
| more on printsyms. |
| |
| * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than |
| "gdb-all.texinfo" |
| |
| * doc/rdl-apps.texi: renamed from rdl-apps.texinfo |
| |
| * Makefile.in, doc/Makefile, doc/gdb.texinfo: |

| |
| * doc/gdbint.texinfo: add short description of configure +template |
| |
| Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com) |
| |
| * doc/gdb.texinfo: update, fix bugs in "Installing" appendix |
| |
| Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for |
| tar file, add dependencies for referenced doc files. |
| |
| Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com) |
| |
| * coffread.c, symfile.c, stack.c: saberized. |
| |
| Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com) |
| |
| * doc/refcard.tex: permuted Essential Commands sec |

| new doc for |
| set/show symbol-reloading |
| default set complaints 0 |

| |
| Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com) |
| |
| * expread.y, coffread.c, dbxread.c, target.c, mem-break.c, |
| cplus-dem.c, values.c, valprint.c, symfile.c, remote.c, |
| breakpoint.c, main.c: lint. |
| |
| Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| Install new configuration scheme for GDB and friends. |
| |
| * config.sub: Translate ordinary names to three-part names. |
| * configure: Use three-part names internally. |
| * configure.in: Translate three-part names to filenames. |
| |
| * README, WHATS.NEW: Update for gdb-4.0. |
| * Makefile.in: Roll VERSION to 3.99. |
| |
| Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h. |
| * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h, |
| tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs |
| to single structures rather than arrays; when passing |
| their address, use &. This avoids trouble with bdead compilers. |
| * mcheck.c: Don't include <stdlib.h>; just declare "void abort();" |
| instead. This avoids portability headaches. |
| * mips-tdep.c (mips_do_registers_info): Only print FP regs if |
| asked to. |
| * source.c (open_source_file): Avoid ANSI const bdeath by |
| skipping declaration and then casting result value. |
| * tm-hp300bsd.h: Clarify comment. |
| * utils.c (strstr): Result is const char *; ANSI bdeath. |
| * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN, |
| since system include file defines it differently from "defs.h", |
| though the two are equivalent for our purposes. |
| * tconfig/hp300bsd: Add m68k-tdep.o. |
| |
| Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * tconfig/sun*4: Remove warnings about system assembler. |
| |
| Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * mcheck.c: Avoid warning about undeclared abort fn. |
| * tm-sparc.h (PC_ADJUST): Avoid calling error() from this; |
| it causes recursive calls to error() when used in cleanups. |
| To do so requires that we make it a function, so we do. |
| * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST. |
| * utils.c (do_cleanups): Remove the current cleanup from the |
| chain *before* calling it, in case error() is called from it. |
| The result won't be pretty, but won't be an infinite loop either. |
| |
| Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com) |
| |
| * dbxread.c (read_struct_type): Grok anon structs for C++. |
| (vb_name, vptr_name): Null terminate these strings. |
| |
| Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| Minor bug fixes from BSD Net2 gdb: |
| |
| * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE |
| returns 0, there is no previous frame. |
| * breakpoint.c (commands_command): If !from_tty, don't call |
| input_from_terminal_p(). |
| * dbxread.c (record_misc_function): Speed up slightly. |
| (compare_psymbols): Ditto. |
| * infcmd.c (do_registers_info): Take a second argument to |
| determine whether to print float registers. "info registers" |
| does not do so anymore. "info all-registers" does, now. |
| * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second |
| arg and ignore it. |
| * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg. |
| * inflow.c (initialize_inflow): Set tflags_ours correctly. |
| |
| Other fixes: |
| |
| * breakpoint.c (bpstat_do_actions): Use a cleanup to restore |
| executing_breakpoint_commands if we are interrupted by error. |
| * coffread.c (init_lineno): Avoid problem with zero-sized linetab |
| versus malloc/free. From: john@labtam.labtam.oz.au (John Carey). |
| * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a |
| catch_errors() so we can setup the frame regardless of whether |
| the shared libs work. |
| * ieee-float.c (double_to_ieee_extended): Get exponent from |
| right place in little-endian systems. From John Carey. |
| |
| Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * main.c: Remove unused terminating_signals and catch_termination(). |
| (long_options): Terminate with a zero element. |
| [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.] |
| (gdb_readline): Make call-compatible with readline. |
| (init_signals): Improve comments re vfork vs. signal. |
| |
| * utils.c (prompt_for_continue): Use new gdb_readline(). |
| If we prompt for continuation, we don't let CR repeat the previous |
| command, once we get back to a prompt. It's too easy to keep |
| hitting CR, expecting "--more--" prompts, and have some long |
| command start repeating on you. |
| |
| Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * blockframe.c (frameless_look_for_prologue): Speed up by |
| calling SKIP_PROLOGUE_FRAMELESS_P if it's defined. |
| * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P): |
| Define two variants, one faster. |
| * sparc-tdep.c (sparc_frame_chain): Use target_read_memory |
| and return zero, rather than giving an error. |
| (setup_arbitrary_frame): Initialize the PC in the new frame. |
| (skip_prologue): Add a second arg saying whether we're just |
| checking for a frameless function or not. |
| |
| * core.c (core_open, core_close, core_xfer_memory): Move |
| section table pointers and bfd* into the target_ops. |
| (core_open): Allow errors in shared lib reading, etc. |
| (core_files_info): Describe shared library sections. |
| |
| * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory, |
| exec_files_info, set_section_command): Move section table |
| pointers and bfd* into the target_ops. |
| (add_to_section_table): Add BFD to section table. |
| |
| * target.c (target_xfer_memory, target_info): Pass target to |
| xfer_memory and target_info functions. |
| * target.h: '' |
| |
| * gdbcore.h: Move struct section_table. |
| * target.h: New home of struct section_table. |
| |
| * solib.c (solib_add): New argument is the target_ops whose |
| section list is to be added to, if any. Reallocate the |
| sections in that target to add any that come from shared libs. |
| (throughout) so_sections renamed to sections. |
| (solib_xfer_memory): Deleted. |
| * tm-sunos.h (SOLIB_ADD): Add target argument. |
| (SOLIB_XFER_MEMORY): Delete. |
| |
| * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c, |
| remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector |
| from target_ops. It's the same on all targets. Add two section |
| pointers to target_ops. |
| |
| * stack.c (find_relative_frame): Dump ancient algorithm for |
| "down", just use handy "next" pointers. |
| (frame_command): Don't error if there is no stack; let user |
| set one. |
| |
| * inflow.c (new_tty_prefork, new_tty): New prefork routine |
| modifies static state in the parent process; new_tty itself |
| runs in the child and modifies the child's file descriptors |
| to match the saved static state. |
| * infrun.c (child_create_inferior): Call new_tty_prefork, |
| fork, then new_tty. |
| |
| * infptrace.c (child_xfer_memory): Add ignored target arg. |
| * remote-eb.c (eb_xfer_inferior_memory): '' |
| * remote-nindy.c (nindy_xfer_inferior_memory): '' |
| * remote-vx.c (vx_xfer_memory): '' |
| * remote.c (remote_xfer_memory): ''. Rename from |
| remote_xfer_inferior_memory. |
| |
| * main.c (main): Only try to attach "corefile" argument if |
| it starts with a digit. |
| |
| * symfile.c (symbol_reloading): New "set/show" variable. |
| (symbol_file_add): Shorten message about symbol reading. |
| (add_symbol_file_command): Merge with add_syms_addr_command, |
| since this should work on all targets now. |
| (stop_whining): Default to zero, to shut up complaints |
| about bad symbol tables on many systems. |
| (free_named_symtabs): Just exit unless symbol_reloading. |
| |
| * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA, |
| and add comment explaining shared library screw. |
| |
| * source.c: #if defined => #ifdef. |
| |
| Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * doc/gdbint.texinfo: Improve doc on porting to new OS's. |
| |
| Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com) |
| |
| * doc/rdl-apps.texinfo: provide default readline-appendix finder |
| (doc/Makefile knows how to make one for local config) |
| |
| * Makefile.in: use doc/Makefile for doc targets |
| |
| * doc/Makefile: GDB documentation now has its own Makefile |
| doc/refcard.tex: renamed from "gdbrc.tex" |
| doc/gdbint.texinfo: add markup in "Cleanups" chapter |
| |
| |
| Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * values.c (baseclass_addr): When reading target memory, use the |
| length of the basetype, not the upper type. We've only malloc'd |
| enough space for the basetype, leading to errors in free(). |
| |
| * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that |
| ends up as a function specially, since we know the actual type of |
| the pointed-to address. This (somewhat) fixes display of |
| expressions that include misc_function_vector names. Try `cond 1 |
| !strcmp("a","b")' then `i b'. |
| |
| * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume(). |
| The child can be proceeded from inside wait_for_inferior in |
| evaluating breakpoint conditions, and DO_DEFERRED_STORES was |
| getting skipped in that case. |
| |
| * expprint.c (print_subexp): Use filtered output, since the |
| subroutines we call use it, otherwise the output is horribly |
| mangled, since output of wrappable stuff comes out late. |
| |
| * Makefile.in: Bump VERSION to 3.98.1 |
| |
| * infrun.c (child_create_process): Use execlp to find the |
| shell to exec our target program. This requires some fiddling |
| with `environ' since there is no execlpe(). |
| |
| Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com) |
| |
| * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files): |
| Minor rearrangement of refcard permits two new make targets-- |
| gdbrc.dvi DVI output for refcard, using CM fonts |
| gdbrc.ps PostScript refcard, using PS fonts |
| |
| Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * GDB-3.98 release. |
| |
| * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98. |
| * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies. |
| |
| Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com) |
| |
| * doc/gdb.texinfo: last changes for release. |
| Minor typo and formatting fixes; incorporated most fixes remaining from |
| filed mail commenting on earlier drafts. |
| |
| Added warnings: pipes don't work in run command; |
| conditions are converse of assertions; |
| step over fn without debug info goes to next fn; |
| vars may have "wrong" values near fn entrance, exit |
| |
| Added example from Kingston on printing repeated nonadjacent values |
| |
| Added explicit mention that in Emacs gdb mode C-c and C-z are like |
| shell mode for signals |
| |
| Renamed "Stepping and Continuing" to "Continuing and Stepping" so it |
| doesn't sound so much like its parent "Stopping and Continuing"; also |
| moved entries on continue to top of section, so they don't get lost. |
| |
| Improved installation directions in appendix, added manual formatting |
| instructions |
| |
| Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * configure.in: Remove xm.h and tm.h even if we aren't linking |
| new ones, so "./configure sun4; ./configure none" does the right |
| thing. Assume that alldeps.mak and depend are already built in |
| srcdir, and avoid running "make" (particularly "make depend", |
| which involves "gcc") from inside configure. Build Makefile |
| directly rather than building Makefile.conf first. |
| * configure: Regenerate with above changes. |
| * Makefile.in: Use $(BISON) to find bison. Roll VERSION |
| to 3.98. Revise gdb.tar.Z procedure to produce a file |
| called gdb-$(VERSION).tar.Z but which unpacks into a |
| directory called "gdb". Move non-source files out of |
| $(SFILES_SUBDIR). Pretty up alldeps.mak with comments. |
| (depend): Don't try to do "gcc expread.y". |
| (expread.o): Update dependencies by hand. |
| |
| Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com) |
| |
| * doc/gdb.texinfo: |
| Fixed a variety of small typos that prevented info from formatting |
| cleanly; altered too-long heading for GPL Appendix, as discussed |
| w/RMS; Changed date on cover to July 91. |
| |
| Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com) |
| |
| * doc/gdb.texinfo: |
| (1) Applied some fixes due to comments from Larry Breed (easier ones |
| through chapsec 5.2) |
| (2) Eliminated use of @footnote---had my doubts about it anyways, and |
| it's broken in latest texinfo |
| (3) Introduced *some* use of [] for optional arguments, where |
| explanation is not simpler by listing cmd w arg and cmd w/out arg |
| separately. Still not using @deffn. |
| (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a |
| couple of headings are too long. Need patches to texinfo or revision |
| to GPL-2. |
| |
| * Partial update to README (which still needs work for this |
| release!): (1) use of configure corrected for new script, |
| (2) "make gdb.dvi" and "make gdb.info" mentioned. |
| |
| Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * symtab.c (lookup_symbol): Don't complain right off about |
| no debug symbols; use the misc function vector first. |
| (list_symbols): Use misc function vector to find symbols |
| that don't have debug info, and print them. |
| (find_pc_symtab): Temporarily avoid fatal() when psymtab |
| PC range doesn't match symtab PC range, as it does on the |
| MIPS because our symtab reading isn't perfect. |
| |
| * dbxread.c (dbx_symfile_read): Make warning about |
| "no debug symbols" slightly nicer. |
| |
| * source.c (select_source_symtab): If "main" symbol exists, |
| but decode_line_spec can't find line info, don't just return |
| a zero; try other source symtabs or give an error. |
| |
| * mipsread.c (parse_partial_symbols): Sort the psymtabs by |
| their low addresses first, then rip through fixing high addrs. |
| |
| * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd, |
| <runene@ifi.uio.no>. |
| (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef. |
| |
| Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com) |
| |
| * Minor, mostly mechanical, cleanup of doc subdir for clean |
| makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4) |
| and gdb.info (post- texinfo2 makeinfo) generated for distribution. |
| |
| Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| Mostly MIPS and general symbol-reading fixups. |
| |
| * doc/gdbint.texinfo: Add documentation on symbol-reading |
| interface. |
| |
| * mipsread.c: Remove kludges around #include "ecoff.h". |
| Remove redefinitions of a_magic, etc, no longer used. |
| (parse_symbol, ): Convert "Internal:" printfs to complain()ts. |
| Fix global overview comments to match symfile.c protocol. |
| (mipscoff_new_init): Eliminate cur_hdr if we have one. |
| (mipscoff_symfile_read): Eliminate unused code. Avoid |
| sorting all the symtabs, when all we have read here is psymtabs. |
| The symtabs are sorted as they are created anyway. Tell |
| condense_misc_bunches whether we're mainline. |
| (psymtab_to_symtab_1): Pass filename when recursing, to make |
| stack trace more informative. |
| (parse_partial_symbols): Assume cur_hdr as argument. |
| (read_mips_symtab): Don't clobber cur_hdr, so it can be freed. |
| Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking |
| the TYPE_NAME of char *, since that's done in symfile.c. |
| (free_numargs, parse_symbol, add_symbol, add_block, |
| shrink_linetable): Declare these fns void. |
| (upgrade_type): Convert tree of if's to switch. Clean up |
| bogus "off == 0" handling with a complaint. Avoid setting |
| field bitpos and bitsize of array with lower and upper bounds. |
| Check specified bitsize of elements against their actual type's |
| bitsize, and complain if different. Complain about unknown |
| type qualifiers. |
| (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *). |
| (psymtab_to_symtab_1): Print names of subsidiary files that |
| are being read in. FIXME, we read far too many files. This code |
| is not the problem, the problem is in parse_fdr where the psymtabs |
| are set up. |
| (cross_ref): Result should indicate that we used one aux entry |
| normally, or two if we encountered a "next" entry. This used |
| to leave the caller pointing at the wrong aux entry. |
| (add_symbol): If overflowed cur_block, reallocate it larger, |
| chase all pointers to it, and complain(), rather than clobber memory. |
| (shrink_block): Use xrealloc rather than xmalloc-and-copy. |
| (new_field): Only allocate one field initially, not two. |
| Pull ++ out of macro argument. Simplify. |
| (_initialize_mipsread): Avoid initialization of importd |
| global_psymbols and static_psymbols. |
| |
| * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab |
| to properly set pst->symtab; avoid searching for it. |
| (symfile_fns): Improve comments, add a FIXME. |
| * dbxread.c: Update comments to reflect symfile protocol. |
| (read_ofile_symtab, end_symtab): Return the symtab. |
| (psymtab_to_symtab_1): Set pst->symtab. |
| |
| * coffread.c (coff_symfile_read): tell condense_misc_bunches |
| whether we're mainline. |
| |
| * symfile.h (sym_fns): Remove unused sym_discard member. |
| * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard. |
| |
| * mtrace.c (mtrace): Take effect if mallwatch is set, even if |
| the environment variable is not. |
| * infcmd.c (finish_command): Use filtered printfs. |
| * cplus-dem.c: Add struct tags to a few unnamed structs. |
| * valops.c (value_coerce_array): Improve comments. |
| * valprint.c (type_print_varspec_suffix): Print array size only |
| if greater than zero. |
| * m88k-tdep.c: Shift some lines left by one space, that had |
| apparently been trashed at some point. |
| * TODO: More things to do, a few got done. |
| |
| Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC. |
| (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve |
| comments. |
| * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC. |
| * expread.y, findvar.c, symmisc.c: Ditto. |
| * printcmd.c (address_info): Update printed forms of LOC_ |
| symbols. Elim LOC_EXTERNAL. |
| (print_frame_args): Keep track of param stack offsets before |
| re-looking up to find the local register param is kept in. |
| |
| * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>. |
| Further integration of mipsread into gdb. Eliminate unused |
| routines, duplicate declarations. Handle static symbols in |
| psymtabs as well as external symbols. When reading symtabs, |
| insert symbols into the correct block (global, static, or a local |
| block). |
| (read_mips_symtab, parse_partial_symbols): Don't pass useless |
| "incremental" arg. |
| (mipscoff_symfile_read): Don't call select_source_symtab. |
| (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate, |
| rather than SYMBOL_VALUE. |
| (parse_external): Comment clobbering of top_stack. |
| (parse_partial_symbols): Update comments. Allocate and parse |
| static symbols as well as external symbols. FIXME, enum values |
| are not handled in this pass, but should be. Inline new_psymbol. |
| Use SYMBOL_VALUE_ADDRESS. |
| (psymtab_to_symtab_1): Read symbols into global static block |
| by default (until enter some function's local block context). |
| (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK. |
| (destroy_all_symtabs, new_psymbol): Eliminate, unused. |
| |
| * source.c (select_source_symtab): Select a source symtab |
| from either the symtabs or, failing that, the psymtabs. |
| (list_command): Update error message. |
| (forward_search_command, reverse_search_command): Use getc, not |
| fgetc, for speed. FIXME, add comment about buffers that die if |
| overrun by long line. |
| |
| * values.c (unpack_field_as_long, modify_field): Avoid shifting |
| by an entire word, which is not portable, if we have a 32-bit |
| field. (Code in dbxread.c already turns such bitfields, if |
| aligned, into ordinary ints, but fixing this will help for other |
| symbol formats and for future changes.) |
| * core.c (core_open): Handle ANSI const brain death. |
| * utils.c (vprintf): Fix varargs typo. |
| |
| Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * findvar.c (find_var_value): Handle &function better. |
| * TODO: Document work needed on &fn and &array. |
| * printcmd.c (print_address_symbolic): New arg is the prefix |
| to print if a name is printed. |
| (print_address_demangle): Honor "set print address" now. |
| Use new arg above to improve spacing of output. |
| * valprint.c (val_print): When printing function pointers, |
| print symbolic form too. |
| * breakpoint.c (breakpoint_1): Use new print_address_symbolic. |
| |
| Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * core.c (memory_error): Reword error msg to mislead less. |
| |
| * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name. |
| |
| * mipsread.c (read_mips_symtab, read_the_mips_symtab, |
| parse_partial_symbols): Use newer BFD internals (external_filehdr |
| and external_aouthdr), byte-swap the fields that we care about |
| before using them, and make the file header data local to |
| read_the_mips_symtab rather than global. |
| |
| Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix |
| from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991. |
| |
| * main.c (command_line_input): Flush stdout and stderr |
| before every call to readline. This reportedly fixes a bug |
| that comes up in Sys V running emacs-gdb and/or xxgdb, |
| when stdin/out are pipes or sockets. |
| |
| Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * configure.in, Makefile.in: Avoid rebuilding "depend" as much. |
| Avoid declaring Makefile dependencies, because GNU Make stupidly |
| tries to update it if we do. |
| |
| * coffread.c: Revise for minor changes to bfd internal coff |
| indexes. |
| |
| * configure: If -template= is given a relative path, make it |
| absolute before recurring in subdirectories. |
| |
| * configure, configure.in, Makefile.in: Install "configure" script |
| as replacement for config.gdb. |
| * config.gdb, Makefile.dist, Makefile.sdir: Remove |
| * README: Update for configure, mostly. FIXME. |
| |
| * Add dec3100 as equivalent to littlemips. Indicate in all host & |
| target config files that they are for the host. When the lines |
| get copied into the Makefile, this makes it more obvious what's |
| up. |
| |
| Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * sparc-opcode.h (trap opcodes): Avoid leading spaces or |
| tabs, which end up in the disassembler output inadvertently. |
| |
| Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| Make it compile cleanly in an ANSI GCC2 environment. |
| |
| * blockframe.c: <stdio.h> |
| * cplus-dem.c: free takes a void *, ifdef __STDC__ |
| * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of |
| LONG_MAX/radix. |
| * defs.h (alloca): Avoid doing anything if alloca already def'd. |
| * stddef.h, stdlib.h: Remove these files. |
| * symtab.c: Avoid declaring qsort, close. |
| * symfile.c: Avoid declaring close. |
| * utils.c (vprintf): Declare "ap" arg as proper va_alist. |
| * sparc-tdep.c: Avoid including lots of Sun-host-specific files. |
| |
| Assorted other changes. |
| * dbxread.c: include "libaout.h", not "liba.out.h". |
| * printcmd.c (print_frame_args): Set recurse properly for |
| indentation of struct and array parameters. |
| * valops.c (value_cast): Allow cast to void. |
| * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent |
| single_step() in a target-independent fashion. |
| * sparc-tdep.c (single_step): Don't call ptrace ourselves, just |
| set up to be ready to continue. This makes us target independent. |
| * infptrace.c (child_resume): Remove call to single_step; now |
| can single step a SPARC target of any kind. |
| |
| Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com) |
| |
| * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB |
| docn into separate sections---basically chapters, plus two loose |
| pieces that can be configured to go in different places. This |
| allows GNU m4 to preprocess the manual without coredumping. |
| |
| * Makefile.dist: tell TeX where to find texinfo. |
| |
| Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com) |
| |
| * Makefile.dist, doc/gdb.texinfo: respectively create, and use, |
| the new target "rdl-apps.texinfo" which captures the Makefile |
| variable that records where to find the Readline libraries. |
| |
| Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h". |
| * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters. |
| * defs.h (const, volatile): Only define if not already defined. |
| * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud. |
| |
| * README: Update for release 3.95. |
| * config.gdb: Don't create readline dir in subdir builds. |
| * main.c: Include with "..." form for non-system include files, |
| so "gcc -MM" for "make depend" works. |
| Include readline files with "...h" rather than <readline/...h>. |
| * mipsread.c: Include "ecoff.h" rather than "intel-coff.h". |
| |
| * coffread.c: Undo minor damage done by Rich Pixley. Use |
| different internal and external representations of COFF |
| data structures. Use new BFD routines for swapping them in and |
| out. |
| * symfile.c (free_named_symtabs): Avoid freeing file names that |
| are null or empty. Old i960 tools seem to produce files that |
| claim to have empty names, causing each successive file read |
| to blow away the previous one. |
| * sparc-xdep.c (deferred_stores): Repair minor damage by Rich. |
| Move deferred_stores to top of file, but don't separate its |
| #define's from its variable. Add commentary. |
| * Makefile.dist: Fix Rich damage; undo "configure" changes in |
| favor of keeping the (working) config.gdb. Move readline |
| library up a notch. |
| |
| Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com) |
| |
| * dbxread.c (read_struct_type): Try to handle g++ version 1 MI |
| debug info. |
| * infptrace.c (fetch_registers): no result, since now void. |
| * tconfig/news: target depends on m68k-tdep too. |
| |
| Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com) |
| |
| * Makefile.dist: added readline/inc-*.texinfo to dependencies for |
| gdb.dvi target |
| |
| * readline/inc-history.texinfo, readline/inc-readline.texinfo: |
| applied various small fixes due to or inspired by RMS comments |
| |
| * doc/gdb.texinfo: finished using all RMS comments, save those for |
| appendices on readline and cmd history (which are in other source |
| files) |
| |
| Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com) |
| |
| * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through |
| chapter 9; (2) documented 'break' command's menu mode for |
| overloaded names, in response to hgs problem report C++ p-31 |
| |
| Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com) |
| |
| * doc/gdb.texinfo: (1) better introductory example; (2) more |
| consistent use of @code, @samp, @file, @kbd throughout; small |
| cleanups to first three nodes; (3) new "Contributors" node; |
| (4) Appendix, Renamed Commands; (5) divert specialized startup |
| instructions to "Targets" chapter for generic manuals, while |
| leaving them up front for manuals specific to specialized |
| environments; (6) apply fixes from RMS comments through chapter 4. |
| |
| * pretex.m4: modify explanatory text slightly (and redefine |
| "regexp") to keep GNU m4 from complaining. (It still crashes |
| later, but one step at a time...) |
| |
| Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * readline/readline.c (update_line): Avoid dereferencing a pointer |
| before comparing it to its bounds. Saber caught this. |
| (init_terminal_io): Don't set BC from the "pc=" termcap variable, |
| and only set PC if tgetstr returned non-null. Saber caught this. |
| |
| Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com) |
| |
| * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor |
| stuff for config manual) here where it counts; updated |
| to use new subdir structure (gdb/doc/). |
| |
| * Makefile: generated from above via |
| config.gdb none |
| before checkin |
| |
| * gdbint.texinfo: added instructions on generating gdb.info* files |
| locally for release. These are ordinary info |
| files, formatted from gdb.texinfo (via gdb-all.texinfo, see |
| Makefile)---but due to use of texinfo 2, can't count on makeinfo |
| to generate these, so we distribute them already formatted. |
| |
| * gdb.texinfo: included full Info node and menu crud (as generated |
| by C-u M-x texinfo-master-menu using the texinfo-2 elisp code). |
| |
| * Makefile: updated "gdb.dvi" target to use M4 preprocessor; |
| put in comments-for-future gdb.info target (one day makeinfo will |
| work again). |
| |
| Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com) |
| |
| * gdb.texinfo: Updated to include new or old undocumented |
| commands, at least the following (perhaps some others I forgot to |
| record): info f, info float, info path, info program, info s, info |
| set, info source, info terminal, info types, info user, set/show |
| print object. |
| Also covered all recent GDB command renames for v4. |
| |
| Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * mipsread.c: Rather than keeping count of how many symtabs |
| and psymtabs we have, for sorting purposes, count them when |
| we need to sort. This fixes bug in rereading of symbol tables. |
| |
| Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com) |
| |
| * infcmd.c: renamed "info path" to "show paths" |

| |
| * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c, |
| symtab.h, target.c, target.h: Lint. |
| * core.c: setup and select frame after reading shared libs, |
| else reading shared libs will clobber them. Lint. |
| * utils.c (error): Force out any buffered wrap text. |
| |
| Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * remote.c: Remove decls of memory_insert_breakpoint |
| and memory_remove_breakpoint, no longer used. (Suggestion of |
| Jan Norden). |
| |
| * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY, |
| to make it easier to interface to "configure"'d libraries. |
| |
| Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com) |
| |
| * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as |
| aliases for set/show print. |

| |
| * cplus-dem.c: Move CPLUS_MARKER define to after defs.h. |

| Remove from_tty arg to mod_path. |
| Put symfile_bfd in {coff,dbx}read.c not symfile.h. |
| Use OP_NULL instead of 0 where dummy enum exp_opcode needed. |
| |
| * tm-sparc.h: Remove GET_RWINDOW_REG. |
| (FRAME_CHAIN): Call sparc_frame_chain. |
| sparc-tdep.c (sparc_frame_chain): New function. |

| xm-tahoe.h: Don't define _DIRENT_. |
| |

| * valprint.c (type_print_varspec_prefix, case TYPE_CODE_METHOD): |
| Don't print " " type_print_base (...) "::" if !passed_a_ptr. |

| been read in, particularly for VxWorks. |
| |
| * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back |

| * coffread.c (end_psymtab): Free named symtabs and psymtabs for |

| queued to the psymtab list. |
| |
| * symfile.c (symbol_file_add): Use filtered printing and wrap it. |
| If we have wiped out any old symbol tables, clean up at end of |

| * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New |

| * exec.c (exec_ops): Add_syms_addr is valid in our tvec. |
| (set_section_command): New command ("section xxx yyy" -- should |
| be renamed to "set section xxx yyy" FIXME) which sets the |
| base address of a section of the exec file, overriding the |
| virtual address that BFD reports. |
| |
| Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * exec.c: Add add_syms_addr_command to exec_ops, so you can |
| load symbols at any address while examining an exec file. |

| Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * tm-i386v.h (FLOAT_INFO): Don't define it, since the code |
| for printing the float info is host-dependent, not |
| target-dependent. FIXME. |
| * i386-pinsn.c: Move #includes to top, remove useless ones. |
| * i386-tdep.c: Don't bother including <.../reg.h> since we |
| don't use it (and it doesn't exist on host systems). |
| |
| * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf. |
| Convert negative numbers properly. |
| (ieee_test): Make numbers really random; fix format arg. |
| |
| * infcmd.c (attach_command, detach_command): Don't repeat on CR. |
| * core.c (core_detach): Unpush core_ops, which might not be on |
| top. We used to just pop the top, which broke things. Don't |
| need dont_repeat() any more. |
| (core_file_command): Psst! Don't repeat it. |
| * remote-nindy.c (nindy_detach): Don't need dont_repeat() now. |
| * expprint.c (print_subexp): Avoid switch fallthru on |

| * frame.h: Fix typo. |
| * inflow.c (kill_command): After killing inferior, print our |
| current frame in the core file, if we have one. |
| (generic_mourn_inferior): When inferior dies, either select |
| the current frame (in the new target, e.g. core file), or |
| set both the current and selected frames to NULL. |
| |
| Changes from Peter Schauer. |
| |
| * infptrace.c: Avoid <sys/ptrace.h> on USG. |
| |
| * Make all file names fit in 14 characters (sigh and damn!): |
| mv hp300hpux-xdep.c hp300ux-xdep.c |
| mv symmetry-xdep.c symm-xdep.c |
| mv symmetry-tdep.c symm-tdep.c |
| mv convex-opcode.h convx-opcode.h |
| mv tm-vxworks960.h tm-vx960.h |
| mv tm-vxworks68.h tm-vx68.h |

| mv gdb-int.texinfo gdbint.texinfo |
| mv remote-sa.m68k.shar rem-m68k.shar |

| xconfig/hp300hpux, xconfig/symmetry: Change names to shorter |
| names. |
| |

| the user-defined commands. |
| |

| |
| * dbxread.c (really_free_pendings): Clear file_symbols |
| and global_symbols after freeing them; otherwise, running |
| this function twice (if it appears twice on the cleanup |
| chain), we try to free things twice. |
| |
| * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr |
| based on text_addr (the address of text in core), not on addr (the |
| offset between text in the .o file and in core). This change |
| is from Peter Schauer. |
| |
| * main.c: Define ALL_CLEANUPS as a cast of zero. |
| (return_to_top_level): Use it. |
| (main): Do all cleanups after each command run as part |
| of the gdb startup sequence. Also do all cleanups before |
| entering the command loop, and every time we exit the command |
| loop and reenter. Before, the cleanups from the startup sequence |
| were being left undone until the first error! |
| (command_loop): Rename do_nothing cleanup to command_loop_marker |
| so we can see it easily when examining the cleanup chain. |
| (init_signals): Add another do_nothing for signal handling. |
| (quit_command): Only try to kill target if it has execution. |
| Problems in the target stack got us into a state where |
| inferior_pid was nonzero but none of the targets had execution. |
| In this state you couldn't exit gdb. |
| |
| * dbxread.c: Two changes from Peter Schauer. |
| (echo_command): Fflush output after an echo command. |
| (show_history): Pass all args to cmd_show_list. |
| |
| * utils.c (init_malloc): Call mtrace to turn on tracing |
| if the environment variable MALLOC_TRACE is set to a file name. |
| * mtrace.c: Add source file which provides a log of every malloc, |
| free, and realloc to a trace file. |
| * mtrace.awk: Add source file which analyzes the trace file. |
| * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}. |
| (VERSION): Roll to 3.94.3. |
| |
| * breakpoint.c (breakpoint_1): Add a space to "i watch" output. |
| (check_duplicates): Don't bother with watchpoints. |
| (set_raw_breakpoint): Comment about danger of this routine. |
| (watch_command): Parse and eval all args before calling |
| set_raw_breakpoint. |
| |
| * solib.c (find_solib): Avoid error in referencing memory to |
| see if any more shared libraries have been added. This is |
| particularly useful if the target has terminated. Bug reported |
| by Peter Schauer. |
| |
| Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de> |
| in bringing up 3.94.2 on the Sun-3. |

| * Makefile.dist: Include CFLAGS in rule for cplus-dem.o. |
| * breakpoint.c (enable_breakpoint): Check for valid watchpoint |
| expression (in scope) before reenabling watchpoint. |
| * signame.c (init_sigs): Add missing declaration of i, fix |
| sys_siglist declaration. |
| * source.c (list_command): Fixed range computation to use |
| lines_to_list (). |
| * stack.c (backtrace_command): Do not allow command if target has |
| no stack, print informative error message. |
| * target.c (target_command): Do not write into command line |
| because this fails if the target command is used in a user defined |
| command. [This change was enhanced by gnu to support any- |
| unique-prefix matching on target names.] |
| * valops.c (value_struct_elt): Avoid infinite loop on an |
| erroneous attempt to print the member of function (try p main.p). |
| |

| |
| * expread.y (name_no_typename): Avoid reduce/reduce errors |
| caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT. |
| Since the GDB parser really doesn't use name_no_typename in a |
| name-only context, the parser can't tell the diff between |
| names and numbers here. Avoid allowing a name_no_typename |
| to be a NAME_OR_*INT to resolve the conflict. |

| |
| Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c): |
| |
| * valprint.c (val_print_fields): bitfield printing didn't handle |
| byte order. Indirect through a few more fns to cope. |
| |
| * values.c (modify_field): also cope with byte order. |

| |
| Cleanup for release 3.94.2: |
| |
| * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD |
| include files. Roll version to 3.94.2. |
| |
| * coffread.c (init_stringtab): Read length into unsigned char |
| array before swapping; don't assume 32-bit longs. |
| |
| * target.c (target_info): Don't bother with get_sym_file, just use |
| the symfile global variable. |
| * symtab.h, symfile.c (get_sym_file): Delete it. |
| |
| * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes. |
| (define_symbol): Set symbol line number to 0 if not gcc-compiled. |
| (read_type): Replace one more error() with complain(). |
| |
| * mipsread.c (parse_partial_symbols): Replace printf with complain. |
| |
| * i960-tdep.c: Fix copyright attribution. |
| |
| * config.gdb: Quote all backquotes in doublequotes. You can |
| quote me on that. BSD 4.4 shell found this one. |
| |
| * infptrace.c (throughout): The third argument to ptrace is an |
| int *, not an int. |
| |
| * infrun.c (wait_for_inferior): When program has terminated, we |
| have to call target_terminal_ours before we pop that target off |
| the stack (e.g. before a call to target_kill or |
| target_mourn_inferior). This fixes problem where a program |
| terminates, then GDB stops for (tty output) and you have to type |
| "fg" to the shell to resume it. FIXME: This code for what to |
| do after termination really should be in normal_stop instead. |
| |
| * gdbcore.h (read_memory_check): Change declaration; it changed |
| names months ago. |
| |
| * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD |
| 4.4 prereleases, this avoids a bug in their sgtty compatability |
| support. |
| * remote.c: Use terminal.h rather than hand-rolling the same. |
| |
| * signame.c, signame.h (psignal): Arg is unsigned, not int. |
| * utils.c (strsave, strstr): Fix arg types. |
| * valprint.c (val_print): lint |
| |
| MIPS symbol table support from Per Bothner: |
| |
| * symfile.c (symtab_fns): Remove initializer table that needs to |
| be hacked for each new symbol file format supported. |
| (add_symtab_fns): New function, chains symbol table |
| handlers into the global list. |
| (symfile_init): Search this list. |
| * symfile.h: Add next pointer, declare add_symtab_fns. |
| * coffread.c (_initialize_coffread): Call add_symtab_fns. |
| * dbxread.c (_initialize_dbxread): Call add_symtab_fns. |
| |
| * mipsread.c (psymtab_to_symtab_1): return void instead of (struct |
| symbol *). Thus, we no longer need the hack to trash |
| pst->filename. Good, since that hack confused code in symfile.c! |
| |
| (reorder_symtabs, destroy_all_symtabs): Removed static |
| all_symtabs, which was used to qsort symtabs in reorder_symtabs. |
| Instead, the latter now uses a temporary array (stack-allocated |
| from an obstack, and then freed). |
| |
| (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they |
| haven't been set in the outermost stBlock of a procedure. This was |
| a problem with f77 binaries on Ultrix 4.?. |
| |
| (new_symtab, new_symbol, new_type): Continue changing code to use |
| obstacks more and otherwise conform to dbxread internal style. |
| Made the free_code of symtabs be free_linetable (as in dbxread) |
| instead of free_contents. This implies memory leaks when reading |
| a new symbol table, until the conversion is finished. Did change |
| (struct symbol) and (struct type) to be allocated on the |
| symbol_obstack. Blocks and blockvectors are among the things |
| still "leaking." |
| |
| * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been |
| tested much, but it solved one problem (reported by Meissner), and |
| cleans up some other things. The problem happened when an |
| included file contains actual code (functions) and not just |
| definitions. The mips coff is a little inconvenient there, since |
| it may cause a procedure to be mapped to the wrong psymtab. |
| |
| * mips-tdep.c (heuristic_proc_desc): Minor cleanup. |
| * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME, |
| this will need work for the new core paradigm. |
| |
| Opcode patches from the net: |
| |
| * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and |
| ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were |
| missing altogether - they are added here. From Bruce Bauman. |
| * mips-opcode.h: The low mask for C0 instructions was too small. |
| From Garrett Lau. I modified the fix to check the entire 32-bit |
| opcode. |
| |
| * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce |
| Bauman. |

| |
| Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04): |
| |
| * dbxread.c (read_type): Pointer subtraction (value_sub in |
| valarith.c) sometimes failed because the types of the |
| pointers being subtracted were not identical. |
| These differed because dbxread.c was allocating pointer types |
| using dbx_alloc_type+smash_to_pointer_type instead of |
| lookup_pointer_type. I failed to find a justification for the |
| former, so I changed it to use the latter. Similarly, I |
| replaced smash_to_function_type by lookup_function_type, |
| and smash_to_reference_type by lookup_reference_type. |
| |
| * mipsread.c (parse_symbol, upgrade_type, parse_procedure, |
| _initialize_mipsread): corresponding changes. |
| |
| * symtab.c (smash_to_{pointer,reference,function}_type): eliminate. |
| |
| * source.c (mod_path): Do tilde_expand on each component of the path, |
| rather than on the (list of) paths as a whole. |
| (print_source_lines): Set first_line_listed in addition to |
| current_source_symtab and current_source_line. If the source was |
| not findable, after a "dir" command to fix the problem, |
| a "list" would get the wrong lines. |
| |
| While I was there... (gnu): |
| |
| * dbxread.c (read_type): Change error to complaint. |
| |
| Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| First attempt at detailed understanding of symbol table memory alloc. |
| |
| * dbxread.c (dbx_symfile_read): Free our string table if we |
| aren't the mainline. Free the "info" struct since we're done with |
| it. |
| (init_psymbol_list): Free any previously allocated psymbol lists. |
| (): FIXME: Should realloc-down the psymbol lists when done reading |
| the main symbol file? |
| |
| * symmisc.c (free_symtab): Free fullname field too. |
| |
| * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D. |
| (REGISTER_ADDR): Make result type unsigned int. |
| |
| * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that |
| define REGEX must also define REGEX1 (its dependency). |
| |
| Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com) |
| |
| * tconfig/i960: No longer works, points you at vxworks960 or |
| nindy960. |
| |
| * xgdb.c, XGDB-README: Remove file. Users can get the much |
| better xxgdb. |
| * Makefile.dist: Remove all trace of xgdb. |
| |
| * breakpoint.c (breakpoint_1): Pass demangle arg to |
| print_address_symbolic. |
