98 * mipsread.c (parse_symbol, parse_procedure): Re-do the way that
99 .gdbinfo. symbols are created. Move creation from parse_procedure
100 to parse_symbol, where it is fairly easy to grow the symtab. This
101 also fixes a symtab trashing bug on all mips-based systems.

194 * Merged in latest RS6000 diffs from Metin G. Ozisik.
195 * xcoffsolib.c, xcoffsolib.h: New files, from Metin.
196 * Various files: Changed #ifdef IBM6000 to IBM6000_HOST

201 * objfiles.h (OBJF_SYMS): Define flag bit for objfile flags.
202 * symfile.c (symbol_file_add): Use OBJF_SYMS to decide whether
203 or not to try reading symbols from a mapped objfile. Plugs memory
204 leak due to shared libraries generating no psymtabs or symtabs.

240 args in prototype, function definition, and function calls. It is
241 now available via the DBX_SYMCOUNT macro using the objfile
243 * dbxread.c (dbx_symfile_read, dbx_symfile_init): Remove the
244 local instance of struct dbx_symfile_info and replace with DBX_*
246 * dbxread.c (dbx_symfile_read): Remove init's of now deleted
247 symfile_string_table and symfile_string_table_size.
248 * dbxread.c (dbx_symfile_finish): Remove now obsolete free of
249 symfile_string_table.
250 * dbxread.c (init_psymbol_list): Use DBX_SYMCOUNT.
251 * dbxread.c (dbx_psymtab_to_symtab): Remove local stringtab and

254 * objfiles.c (allocate_objfile): Move calls to init_malloc()
255 to prior to any calls to mmalloc for the objfile specific heap.
256 * utils.c (init_malloc): Document the requirement that for each
257 heap for which corruption checking is desired, that init_mmalloc
258 must be called prior to any mmalloc calls on the heap.
260 Thu Mar 26 13:20:06 1992 Per Bothner (bothner@cygnus.com)
262 * rs6000-pinsn.c: Make dis-assembly output more like
263 other targets: Don't print instruction in hex before

269 * c-exp.y, gdbtypes.h: Add builtin_type_signed_char.
270 * cplus-dem.c: Support "Sc" meaning "signed char".
272 Wed Mar 25 15:21:44 1992 Stu Grossman (grossman at cygnus.com)
274 * configure.in: fix iris/iris3.
276 Wed Mar 25 14:55:48 1992 Per Bothner (bothner@cygnus.com)
278 * command.c, main.c (various places): Use ctype.h macros
279 (such as isupper(x)), instead of hard-wiring in ASCII-isms
280 (such as (x >= 'A' && x <= 'Z')).
281 (There are still more of these in other files.)
282 * main.c (defined_command): Lower-case the user's
283 new command before entering it. Needed because
284 command lookup is case-insensitive (and also lower-cases).
285 (Based on Metin's earlier patch.)
287 Tue Mar 24 23:27:01 1992 K. Richard Pixley (rich@cygnus.com)

305 * config/rs6000.mh: Update (for Fred's new mmalloc)
306 flags to disable use of GNU malloc/mmalloc.
307 * munch: Change SYSV rule to allow .text before the label,
308 as well as after, to work for AIX.
309 * gdbtypes.h: Minor clarifiction.
311 Tue Mar 24 07:26:19 1992 Michael Tiemann (tiemann@cygnus.com)
313 * buildsym.c (read_struct_type): Handle cretinous dbx symbol name
314 continuation in yet another place (between method declarations).
316 Mon Mar 23 23:01:41 1992 Stu Grossman (grossman at cygnus.com)
318 * mips-tdep.c: include symfile.h and objfiles.h to fix
321 Mon Mar 23 15:49:14 1992 Per Bothner (bothner@cygnus.com)

338 tm-symmetry.h, tm-tahoe.h, tm-umax.h, tm-vax.h, m88k-tdep.c,
339 mips-tdep.c (FRAME_CHAIN): Renamed outside_startup_file to
340 inside_entry_file() and logic changed appropriately.
341 * blockframe.c (outside_startup_file): Renamed to
342 inside_entry_file() and logic changed appropriately.
343 * blockframe.c (inside_main_scope): Renamed to inside_main_func()
344 and logic changed to use per-objfile specific fields.

374 * tm-68k.h, tm-convex.h, tm-h8300.h, tm-i386v.h, tm-irix3.h,
375 tm-merlin.h, tm-mips.h, tm-pyr.h, tm-rs6000.h, tm-sparc.h,
376 tm-sun386.h, tm-tahoe.h, tm-umax.h, tm-vax.h (FRAME_CHAIN_VALID):

382 * symfile.h (struct objfile): Removed, moved to objfiles.h.
383 * symfile.h, objfiles.h (allocate_objfile, free_objfile,
384 free_all_objfiles, iterate_over_objfiles, iterate_over_symtabs,
385 iterate_over_psymtabs, have_partial_symbols, have_full_symbols,

391 Thu Mar 19 18:49:45 1992 Per Bothner (bothner@cygnus.com)
393 More C++ improvements (pointers to members, qualified names).
394 * c-exp.y: Support exp.type::name and exp->type::name
395 syntaxes. (Unfortunately, doesn't work for static members.)
396 * c-exp.y, eval.c: Make type::~type work better.
397 * eval.c (evaluate_subexp: OP_SCOPE): Replace use of
398 value_static_field by value_struct_elt_for_reference.
399 * eval.c (evaluate_subexp): Merge code for STRUCTOP_MEMBER
400 and STRUCTOP_MPTR; cast arg1 to domain-type of arg2.
401 * eval.c (evaluate_subexp): Remove special case for UNOP_ADDR
402 for OP_SCOPE operand; no point in it now that we use lazy
403 reading of values, and use "reference to member" objects.
404 * gdbtypes.h: Clarify comment.
405 * valops.c: Change value_struct_elt_for_address to return
406 a reference (or variable), rather than a pointer. Change
407 the name to value_struct_elt_for_reference to reflect this.
408 Returning a reference instead of a address provides a
409 generalization, since we can use the routine for both
410 class::name as well as &class::name.
411 Also, recurse to handle multiple inheritance properly.
412 * valprint.c: Moved code to print pointer-to-members
413 to new function point_class_member. This allows a
414 "reference-to-member" to be printed using the same code.
415 * valprint.c (type_print_varspec_prefix): Avoid printing
416 "struct " for domains of class-member types.
417 * valops.c (search_struct_field): Inline code for simplified
418 version of value_static_field (which can then be deleted).
419 * value.h: Rename value_struct_elt_for_address to
420 value_struct_elt_for_reference. Delete value_static_field.

574 * symmisc.c (free_symtab_block): Now takes and uses current
576 * symmisc.c (throughout): Change from using per-objfile
577 xmalloc/xrealloc/free functions to xmmalloc/xmrealloc/mfree.
578 * symtab.c (cplus_mangled_symbol): Cast return value to avoid
579 Sun compiler grumblings when PTR is char *.
580 * symtab.c (lookup_symbol): Cast return value of iterate_over_
581 msymbols() to correct pointer type.
582 * utils.c (warning_pre_print): Initialize to "\nwarning: ".
583 * utils.c (fatal, fatal_dump_core): Ensure that the fatal

595 mapped malloc region.
596 * utils.c (print_spaces): Use xmalloc to get the buffer.

603 * xcoffread.c: Only enable compilation of debugging functions
604 if IBM6000 is defined. Fails to compile otherwise.
606 Fri Mar 13 15:51:11 1992 K. Richard Pixley (rich@cygnus.com)
608 * Makefile.in: pass MAKEINFO down on info.
610 Fri Mar 13 12:56:36 1992 John Gilmore (gnu at cygnus.com)
612 * mipsread.c (mipscoff_symfile_read): Eliminate a lot of
613 useless code, including an lseek to an uninitialized variable.
614 Reported by Jim Williams <jimbo@wrs.com>.
616 Thu Mar 12 11:56:46 1992 Per Bothner (bothner@cygnus.com)
618 Merged in patches from metin@ibmpa.awdpa.ibm.com (Metin G.
619 Ozisik) (dated Fri, 6 Mar 92 17:51) for the rs6000.
620 * minsyms.c, symfile.c: Changes that may be generally
621 applicable, but are #ifdef IBM6000 for now.
622 * rs6000-xdep.c: Fixed typo in comment.
623 * rs6000-tdep.c: Non-substatial changes.
624 * xoffread.c: The main change here is addition of some
626 * xoffexec.c: More changes.

630 * solib.h, infrun.c, tm-rs6000.h: Add a PID parameter
631 to SOLIB_CREATE_INFERIOR_HOOK macro.
633 Sun Mar 8 21:17:48 1992 Fred Fish (fnf@cygnus.com)
635 * symfile.h: Add prototype for iterate_over_msymbols().
636 * symtab.c (cplus_mangled_symbol): Add function.
637 * symtab.c (lookup_symbol): Call cplus_mangled_symbol via
638 iterate_over_msymbols to find demangled C++ symbol.
639 * xcoffexec.c (relocate_minimal_symbol): Return meaningful
640 value to iterate_over_msymbols().
641 * xcoffexec.c (vmap_symtab): Ignore return from iterate_over_

648 Thu Mar 5 23:56:01 1992 John Gilmore (gnu at cygnus.com)
650 * ecoff.c: Move to ../bfd/coff-msym.c.
651 * config/mt-*mips: Remove ecoff.o from the configuration.
652 * remote.c (): Add newline to initial +.
653 (remote_resume): Mention how to cope with signals.
654 (remote_interrupt): Add debug msg.
655 (remote-wait): Implement new 'T' reply, which includes
656 status, PC, and FP all in a single short message.
657 (putpkt): Add further debugging of packet acks.
658 * mipsread.c (fixup_symtab): Also swap RFD's.
659 (parse_partial_symbols): Avoid bug on unknown symbol types.
660 * Makefile.in (VERSION): Roll to 4.4.5.
661 * mips-tdep.c (heuristic_proc_start): Avoid long delays
662 for remote MIPS by limiting heuristic to 200 byte search.
663 (heuristic_proc_desc): Byte-swapping.
664 (mips_print_register): Cope with failure of
665 read_relative_register_raw_bytes. Byte-swap integers for
667 * mips-pinsn.c (print_insn): Byte-swap instruction.
669 Thu Mar 5 12:32:09 1992 Stu Grossman (grossman at cygnus.com)
671 * config.sub configure.in config/.Sanitize config/mh-irix4
672 gdb/.Sanitize gdb/configure.in gdb/mips-tdep.c gdb/mipsread.c
673 gdb/procfs.c gdb/signame.h gdb/tm-irix3.h gdb/tm-mips.h

675 gdb/config/mh-irix4 texinfo/configure.in: Port to SGI Irix-4.x.
677 Wed Mar 4 11:56:42 1992 Fred Fish (fnf@cygnus.com)
679 * defs.h, utils.c: xrealloc takes PTR as first arg.
680 * defs.h: Reword confusing comment about ANSI prototypes.
681 * defs.h: Some minor whitespace changes.
682 * infrun.c (wait_for_inferior): Compare int tmp to int 0,
683 not NULL, which can be (void *).
684 * tm-amix.h, tm-i386v4.h: Add defines for setjmp/longjmp handling.
685 * tm-i386v.h (SP_ARG0): Define
686 * xm-sysv4.h: Back out of change for missing prototypes.
687 * i386-tdep.c (get_longjmp_target): Add function.
689 Wed Mar 4 05:46:11 1992 K. Richard Pixley (rich@rtl.cygnus.com)
691 * Makefile.in: install man page too.
693 Tue Mar 3 15:11:52 1992 Michael Tiemann (tiemann@cygnus.com)
695 * All GDB files that #include defs.h: Removed stdio.h.
696 (defs.h): #include stdio.h.
698 Mon Mar 2 23:00:12 1992 Steve Chamberlain (sac@thepub.cygnus.com)
700 * gdbtypes.c (lookup_pointer_type): initialize the TYPE_LENGTH of
701 a ptype to reflect the setting of TARGET_PTR_BIT. Set the
702 TYPE_FLAGS of a ptype to TYPE_FLAG_UNSIGNED.
703 * tm-h8300.h, h8300-tdep.c, remote-hms.c: personal checkpoint
704 * printcmd.c (print_address): if ADDR_BITS_REMOVE is defined, use
705 it before printing out the hex shape of an address.
707 Sun Mar 1 17:41:09 1992 Per Bothner (bothner@cygnus.com)
709 * rs6000-xdep.c (frame_initial_stack_address): Move
710 code to set frame->cache_fsr into new separate function
711 frame_get_cacahe_fsr. This allows fixing a fatal error.
712 * xcoffexec.c: Turn previously suppressed error
713 message back on, after cleaning up BFD.
715 * breakpoint.c (breakpoint_re_set): Removed (at least for now)
716 printing of blank line, since it cases printing of an
717 extra blank line. Is this intended? It does mess up
719 * defs.h: Put back declarations of malloc and realloc,
720 but protected by #ifndef MALLOC_INCOMPATIBLE.
721 * objfiles.c: Undo previous change: Use malloc/realloc
722 for objfile malloc/realloc fields (but add a cast).
723 * xcoffexec.c: Suppress an error message (for now).
725 Sat Feb 29 14:43:02 1992 Per Bothner (bothner@cygnus.com)
727 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
728 [Mail dated Fri, 21 Feb 92 13:14:54 -0800]
729 * buildsym.c: Use smash_to_pointer_type() to handle forward type
731 * xcoffread.c: Modifications to C_DECL storage class handling, and
732 introduction of an old smash_to_pointer_type() routine.
734 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
735 [Mail dated Thu, 20 Feb 92 13:57:16 -0800]
736 * rs6000-xdep.c, rs6000-tdep.c, tm-rs6000.h: function_frame_info()
737 parameters have been modified.
739 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
740 [Mail dated Thu, 20 Feb 92 10:10:05 -0800]
741 * rs6000-tdep.c: Before Feb 5 92, register_valid[] array was not used,
742 and fetch_inferior_registers() always fetched all the registers
743 resulting valid register values at hand all the time. Pushing a dummy
744 frame did not require validating all register values first. After
745 putting the above mechanism into action, we didn't have valid registers
746 values always ready. Thus, all registers need to be fetched before
747 pushing a dummy frame now.
749 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
750 [Mail dated Thu, 13 Feb 92 16:22:44 -0800]
751 * rs6000-xdep.c: frame_initial_stack_address() function to calculate
752 the starting address (actual frame address) of a frame.
753 * rs6000-tdep.c: modifications to function_frame_info() to see if
754 function reserves a frame pointer register (alloca register)
755 * tm-rs6000.h: EXTRA_FRAME_INFO, FRAME_ARGS_ADDRESS and
756 FRAME_LOCALS_ADDRESS has been updated to support debugging of
757 functions with alloca() calls.
759 Sun Mar 1 13:13:39 1992 Fred Fish (fnf@cygnus.com)
761 * xm-sysv4.h: Provide definitions/prototypes for host environment
762 functions for which no definitions or prototypes are provided in
763 any currently included gdb or host environment header files.
764 For SVR4, this currently includes malloc and realloc, which cannot
765 be portably prototyped in any gdb include file.
767 Sat Feb 29 14:43:02 1992 Per Bothner (bothner@cygnus.com)
769 * buildsym.h: Remove obsolete variable file_stabs.
771 * Makefile.in: Move place where configure merges in host-
772 and target-dependent fragments later, so the latter
773 can override (say) GNU_MALLOC.
774 * config/mh-rs6000: Use system malloc. Otherwise, I
775 ended up with *two* incompatible versions of malloc
776 (functions in libc would call the malloc in libc).
777 I assume this is a shared library problem.
779 * remote.c: Fix (presumed) typo.
780 * objfiles.c: Use xmalloc/xrealloc instead of
781 malloc/realloc (since the latter are no longer declared).
783 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
784 [Mail dated Thu, 6 Feb 1992 10:22:02 -0800]
785 * rs6000-xdep.c: Improvements to fetch_inferior_registers() to
786 handle individual registers.
787 * tm-rs6000.h: Fix SAVED_PC_AFTER_CALL macro to handle pc value
788 correctly in case it wasn't cached yet. (A problem showed up
789 after fetching individual registers.)
790 * buildsym.c: Disable type_synonym_name's type name overwriting
791 in cases it is unnecesary. rs6000 portation doesn't use
792 type_synonym_name, and it used to nullify type names
793 * xcoffread.c: to handle g++'s typename abbreviation, fill in a
794 type's name as soon as space for that type is allocated.
795 * xcoffread.c: ignore a section's lineno information if it is
796 not `.text'. (In rs6000 bfd portation integration, skipping over
797 `.pad' sections are ignored since it was in machine independent
798 part of the code. Thus, a problem of fake sections with invalid
799 lineno information arised.)
801 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
802 [Mail dated Thu, 6 Feb 1992 13:26:22 -0800]
803 * rs6000-tdep.c: make function_frame_info() work whether or not
804 reading from a core file.
805 * tm-rs6000.h: Implementation of FRAME_FIND_SAVED_REGS macro.
807 * infrun.c. main.c, printcmd.c. symtab.c:
808 More changes from IBM for rs6000.
811 Thu Feb 27 22:57:19 1992 Per Bothner (bothner@cygnus.com)
813 * rs6k-opcode.h, tm-rs6000.h, xm-rs6000.h, rs6000-tdep.c,
814 rs6000-xdep.c, xcoffexec.c, xcoffread.c:
815 Merge in changes (mostly from IBM) for RS6000.
816 * breakpoint.c, buildsym.c, infptrace.c, stack.c, symtab.c:
817 More changes from IBM for RS6000. These are in machine-
818 independent code, and probably could do with some cleaning
819 up. The most questionable of these are #ifdef IBM6000.
820 * infrun.c, sparc-tdep.c: Pass a parameter (signal number)
821 to single_step() (for consistency with rs6000 and i860).
822 * utils.c: Allow the 1st arg to xrealloc to be NULL
823 (in which case do malloc). This removes the need for
824 some tests in xcoff code (and perhaps other places?).
825 * coffread.c: Removed variables last_source_file,
826 type_vector, and type_vector_length as these are now
827 defined by buildsym.[ch].
828 * defs.h: Remove prototypes for malloc and realloc, since
829 these should only be used to implement xmalloc and xrealloc,
830 and they conflict with <stdlib.h> in AIX - where they
831 return void* even when __STDC__ isn't defined. Sigh.
832 * munch: Recognize *initialize* in data as well as text
833 (AIX uses data). Also, incorporate a patch from Garrett
834 Wollman <wollman@uvm-gen.uvm.edu> to make the sed script
835 much more sensible, by only trying to match the name of
836 the initialize_foo function, and not the junk before it.
838 Thu Feb 27 20:07:43 1992 Stu Grossman (grossman at cygnus.com)
840 * breakpoint.c (breakpoint_re_set_one): Don't reset breakpoint
841 unless symbol table indicates that something has changed.
843 Thu Feb 27 11:48:47 1992 John Gilmore (gnu at cygnus.com)
845 * remote.c: Make it work for embedded MIPS. Increase buffer
846 size, and use throughout. Round buffer size up if too many regs.
847 Support baud rate setting and try for an 8-bit path. If

1289 sun386-xdep.c, symm-xdep.c, target.c, ultra3-xdep.c, utils.c,
1290 value.h: Prototypes for static functions; lint.
1291 * gdbtypes.h: Empty file to ease transition.
1293 Thu Feb 20 16:43:13 1992 Fred Fish (fnf at cygnus.com)
1295 * environ.h, expression.h, frame.h, gdbcmd.h, gdbcore.h,

1304 remote-hms.c, remote-mm.c, remote-nindy.c, remote-vx.c, remote.c,
1305 target.c, target.h, valarith.c, valops.c, value.h, xcoffexec.c:
1306 Remove to_call_function and target_call_function, since it
1307 always calls the same thing (call_function_by_hand).
1308 * core.c, exec.c, solib.c: Rename target_ops sections =>
1310 * infcmd.c, inflow.c, infptrace.c, infrun.c, main.c, target.c,
1311 target.h: target_kill takes no args.
1312 * language.c (language_info): Scaffolding to allow briefer
1313 messages when the current language changes. FIXME.
1314 * xm-amix.h, xm-i386v4.h, xm-stratus.h: Define NORETURN to avoid
1315 complaints about volatile functions.
1316 * xm-sysv4.h (HAVE_MMAP): Define.
1318 Thu Feb 20 09:04:18 1992 Fred Fish (fnf at cygnus.com)
1320 * defs.h: Include ansidecl.h and PARAMS macro. Use PARAMS
1321 to make prototypes for all functions declared here.

1325 * ieee-float.h: Use PARAMS for prototypes; make some params const.
1326 * ieee-float.c, valarith.c: Include <stdio.h>. Lint. b*=>mem*.
1327 * m2-exp.y: Remove unused CONST; Rename OR and AND.
1328 * utils.c: Avoid declaring malloc and realloc. Lint.

1331 Mon Feb 17 07:13:27 1992 Fred Fish (fnf at cygnus.com)
1333 * dwarfread.c (process_dies): Add case to handle TAG_pointer_type
1334 DIE's. Add new function read_tag_pointer_type() to read them.
1336 * dwarfread.c (dwarf_read_array_type, read_subroutine_type):
1337 When creating a new user defined type, check to see if a partial
1338 type already exists, and if so, bash it to fit.
1340 Fri Feb 14 19:00:17 1992 John Gilmore (gnu at cygnus.com)
1342 * coffread.c (decode_base_type): Pass long, not union.
1343 Fix by Eric Valette, ev@chorus.fr.
1345 Thu Feb 13 17:14:28 1992 Fred Fish (fnf at cygnus.com)
1347 * elfread.c (elf_symtab_read): Fix code to correctly track
1348 changes in bfd for absolute symbols.
1350 Thu Feb 13 12:43:29 1992 Stu Grossman (grossman at cygnus.com)
1352 * xm-vaxbsd.h: Close off comment.
1354 Thu Feb 13 07:45:19 1992 Fred Fish (fnf at cygnus.com)
1356 * xm-sysv4.h: Define NEED_POSIX_SETPGID.
1358 Fri Feb 7 11:51:12 1992 Per Bothner (bothner at cygnus.com)
1360 * mips-tdep.c (mips_print_registers): Print correct register
1361 number for double pseudo-registers.
1363 Fri Feb 7 07:56:05 1992 John Gilmore (gnu at cygnus.com)
1365 * buildsym.c (read_struct_type): Avoid double-bump of parse ptr
1366 in the op$::OPERATOR. case. From Steven McCanne,
1367 <mccanne@horse.ee.lbl.gov>.
1369 * exec.c (set_section_name): Pass arg to exec_files_info;
1370 only call it if interactive. From Francis Kauth <fk@tv.tv.tek.com>.
1372 Thu Feb 6 17:41:32 1992 John Gilmore (gnu at cygnus.com)
1374 * main.c (print_gdb_version): Copyright msg: only this year.
1375 (cd_command): Avoid changing current_directory on error.
1377 Thu Feb 6 15:14:01 1992 Per Bothner (bothner at cygnus.com)
1379 * mipsread.c (parse_partial_symbols): Handle dependencies
1380 between partial symbol tables (when not doing stabs-in-ecoff).
1381 (This used to be handled by parse_fdr, but parse_fdr was
1382 incompatible with handling stabs-in-ecoff, so the code
1383 was re-written to not use parse_fdr. Unfortunately,
1384 the logic to handle dependencies was overlooked.)
1386 Thu Feb 6 11:51:39 1992 Steve Chamberlain (sac at rtl.cygnus.com)
1388 * coffread.c (read_enum_type): Use the size of a target int when
1390 * defs.h: added new #define for TARGET_PTR_BIT, defaults to size
1392 * h8300-tdep.c, remote-hms.c, tm-h8300.h: too many changes to count
1393 * symtab.c (lookup_reference_type, lookup_ptr_type): use
1394 TARGET_PTR_BIT to determine size of a pointer
1395 * values.c (unpack_long): when unpacking a REF or a PTR don't
1396 assume the size of the type.
1398 Wed Feb 5 22:29:59 1992 John Gilmore (gnu at cygnus.com)
1400 * mipsread.c (parse_symbol): Avoid clobbering enum pointer when
1401 looking at its members. Improve guess between struct and union,
1402 only assuming union if multiple members have offsets of zero.
1404 Tue Feb 4 18:05:44 1992 Per Bothner (bothner at cygnus.com)
1406 * mipsread.c: Use (FP0_REGNUM-32) instead of magic number 6.
1407 (This is just for clarity - and one day permitting us to
1408 change FP0_REGNUM from 38 to 32, which would make more sense.)
1409 * tm-mips.h: Added STAB_REG_TO_REGNUM macro, so that
1410 register numbers in stabs-in-ecoff get handled correctly.
1412 Sat Feb 1 04:45:10 1992 Stu Grossman (grossman at cygnus.com)
1414 * xm-vax.h, xm-vaxult.h, xm-vaxbsd.h, config/mh-vaxult,
1415 config/mh-vaxbsd, configure.in: Split up config stuff for Vaxen
1416 into BSD and Ultrix.
1418 Sat Feb 1 04:39:41 1992 John Gilmore (gnu at cygnus.com)
1420 * dbxread.c (dbx_symfile_init): Call malloc, not xmalloc.
1422 Sat Feb 1 04:15:41 1992 Stu Grossman (grossman at cygnus.com)
1424 * Makefile.in: Increment version to 4.4.1.
1425 * main.c (print_gdb_version): Update copyright notice.
1427 Sat Feb 1 01:43:11 1992 Per Bothner (bothner at cygnus.com)
1429 * mipsread.c: Prepend "struct " to the names of structure
1430 types, and similarly for enums and unions. (This used
1431 to be done, but got lost in the re-write to "guess" the
1432 difference between enum/struct/union.)
1433 Also, guess that a tag is an enum if the first member
1436 Fri Jan 31 21:45:51 1992 Stu Grossman (grossman at cygnus.com)
1438 * xm-vax.h: #ifndef ultrix around #include of endian.h and
1441 Fri Jan 31 00:05:01 1992 John Gilmore (gnu at cygnus.com)
1443 * Projects: Patching executables is done.
1444 * Makefile.in (VERSION): Roll to gdb-4.4.
1445 * README, WHATS.NEW: Update for gdb-4.4.
1447 * symfile.c (reread_symbols): Whenever we reread one object
1448 file's symbols, we must restart the scan, because the object_files
1449 chain has been permuted.
1451 * exec.c (exec_files_info): Split out into print_section_info.
1452 Print BFD filename of each section if it's not the default one.
1453 * core.c (core_files_info): Call print_section_info.
1455 * xm-vax.h: Include a few system header files whose definitions
1456 must precede defs.h.
1457 * language.c, language.h: Make some things const.
1458 * expression.h, main.c: const spreads like ooze.
1460 * mem-break.c (break_insn, break_insn_size): Use unsigned chars,
1461 since BREAKPOINT values can be >0x80.
1463 Thu Jan 30 17:21:14 1992 Stu Grossman (grossman at cygnus.com)
1465 * infrun.c, xm-i386sco.h: SCO needs to use setpgid().
1467 Thu Jan 30 01:04:23 1992 John Gilmore (gnu at cygnus.com)
1469 * sparc-pinsn.c: Remove kludge for preferring architectures.
1470 Remove #ifdef's for SORT_NEEDED. We need to sort the table, now
1471 and forever. Add `add' instruction to the set that get checked
1472 for a preceding `sethi' in order to print an absolute address.
1473 Corresponding changes in ../include/opcode/sparc.h needed
1474 to eliminate garbage instructions.
1476 Wed Jan 29 19:24:34 1992 Per Bothner (bothner at cygnus.com)
1478 * mipsread.c (parse_partial_symbols): Make sure partial
1479 symbols are created for external symbols (as used to be
1480 the case). This is a bit of a pain with the mips-coff.
1481 It uses a table which points to all of the external
1482 symbols belonging to a particular FDR or psymtab.
1483 Once we've generated this table, we might as well save
1484 it, and then use it in psymtab_to_symtab_1 to find
1485 the symbols to pass to parse_external().
1486 * symfile.c, symfile.c: New function start_psymtab_common
1487 to share the common parts of allocating a new psymtab
1488 for dbxread, mipsread (and later dwarfread). Its code
1489 was pulled out from start_psymtab in dbxread.c.
1490 * dbxread.c (start_psymtab): Use start_psymtab_common().
1492 * valprint.c (val_print): If there is an error when trying
1493 to print a string, check to see if there really is a problem
1494 by reading just one character. If that works, assume
1497 Wed Jan 29 18:58:43 1992 Stu Grossman (grossman at cygnus.com)
1499 * sparc-pinsn.c (compare_opcodes): Make it prefer v6, v7,
1500 cypress, v8 mnemonics in that order.
1502 Tue Jan 28 17:32:13 1992 Per Bothner (bothner at cygnus.com)
1504 * sparc-pinsn.c: Put the qsort() back in.
1506 Mon Jan 27 18:51:03 1992 John Gilmore (gnu at cygnus.com)
1508 * findvar.c (read_register, write_register): Handle machines
1509 where REGISTER_TYPE is not the same size as "int".
1511 Handle debug symbols in dynamically loaded (relocated) code:
1513 * dbxread.c (read_ofile_symtab): Fix up N_CATCH better. Pass
1514 offset to process_one_symbol.
1515 (process_one_symbol): Take new offset parameter. Add it into
1516 appropriate symbol types to relocate symbols to loaded addresses.
1517 Handle all possible symbol types, and complain() about types that
1518 we don't expect to see.
1519 * mipsread.c (psymtab_to_symtab_1): Pass offset of zero to
1520 process_one_symbol (FIXME, should pass real offset).
1524 * breakpoint.c (resolve_sal_pc): Split out code to resolve a
1526 (set_breakpoint, break_command_1, until_break_command,
1527 catch_command_1, breakpoint_re_set_one): Use it.
1528 * symtab.h (resolve_sal_pc): Declare.
1529 * infcmd.c (jump_command): Use resolve_sal_pc.
1531 * source.c (list_command): Shorten "FILE, line N" to "FILE:N".
1533 * putenv.c (putenv): Avoid unportably casting pointers to unsigneds.
1535 * c-exp.y (yylex): `this' and `template' are only tokens in C++.
1537 * xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
1538 xm-np1.h, xm-pn.h, xm-pyr.h, xm-rtbsd.h, xm-symmetry.h, xm-umax.h:
1539 Remove MISSING_VPRINTF declaration, and superfluous "kgdb" defines.
1541 Mon Jan 27 15:46:21 1992 Stu Grossman (grossman at cygnus.com)
1543 * dbxread.c (process_one_symbol): Make a first cut at handling
1544 symbol tables generated by Sun's acc. (#ifdef'd out, FIXME.)
1546 * symtab.c (find_pc_line): Fix stepping into and out of #included
1549 Mon Jan 27 13:00:55 1992 Stu Grossman (grossman at cygnus.com)
1551 * Makefile.in (OPCODES): Remove OPCODES defs and refs. There is
1552 no longer any need to copy ../include/opcode/* into gdb.
1554 Mon Jan 27 12:30:38 1992 John Gilmore (gnu at cygnus.com)
1556 * ChangeLog, ChangeLog-9091: Split ChangeLog at 1992.
1558 Sun Jan 26 19:05:40 1992 Per Bothner (bothner at cygnus.com)
1560 * valprint.c (type_print_base, type_print_method_args):
1561 Print C++ constructor methods without bogus "return type."
1563 Sat Jan 25 15:57:59 1992 Fred Fish (fnf at cygnus.com)
1565 * infptrace.c (child_xfer_memory): Parameter "target" should
1566 be a pointer to a structure, not the entire structure.
1568 Fri Jan 24 01:30:27 1992 Fred Fish (fnf at cygnus.com)
1570 * depend: Convert the couple of references to ansidecl.h that
1571 used the local gdb version to use the ../include version.
1573 Thu Jan 23 22:24:43 1992 Fred Fish (fnf at cygnus.com)
1576 (child_xfer_memory): Takes pointer to a struct, not entire struct.
1577 (inferior_proc_init): Fix non-ANSI version of args.
1578 (attach): Call print_sys_errmsg with correct number of args.
1579 (mappingflags): Make static, does not need to be global.
1581 * i386-tdep.c (i386_frame_num_args): Takes a pointer to a struct
1582 not the entire struct itself.
1584 * valops.c (value_assign): Cast some args to modify_field() and
1585 {read,write}_register_bytes() correctly.
1587 * ansidecl.h: Removed, is duplicate of ../include/ansidecl.h
1589 * Makefile.in (MALLOCSRC): Removed reference to removed local
1592 * dwarfread.c (list_in_scope): Needs an initial value, use file
1595 Mon Jan 20 19:06:28 1992 Stu Grossman (grossman at cygnus.com)
1597 * main.c (main): Make option_index local to keep new getopt happy.
1598 main.c, solib.c, Makefile.in: Update copyright notices.
1600 Mon Jan 20 08:54:00 1992 Michael Tiemann (tiemann at cygnus.com)
1602 * cplus-dem.c (cplus_demangle): Correctly demangle destructors.
1604 Sat Jan 18 17:17:45 1992 Stu Grossman (grossman at cygnus.com)
1606 * Makefile.in (HFILES): Add partial-stab.h.
1608 Sat Jan 18 16:45:01 1992 Fred Fish (fnf at cygnus.com)
1610 * config/mh-stratus, config/mt-stratus, tm-stratus.h, xm-stratus.h:
1611 New files for stratus. Not complete enough to actually build
1612 on the Stratus machine; that awaits copyright assignment for
1615 * Makefile.in (USER_CFLAGS): Add macro specifically reserved
1616 for getting custom flags into CFLAGS when doing makes.
1618 * configure.in: Add config information for stratus.
1620 Thu Jan 16 00:51:46 1992 Fred Fish (fnf at cygnus.com)
1622 * dbxread.c (process_one_symbol): Pass address of structure

1632 * dwarfread.c (locval): Add offreg flag to indicate location
1633 values that are computed off a base register.
1635 * dwarfread.c (new_symbol): Rework TAG_global_variable and
1636 TAG_local_variable cases to account for static variables
1637 within function scopes.
1639 Tue Jan 14 12:28:52 1992 Stu Grossman (grossman at cygnus.com)
1641 * inflow.c: remove #include <sys/dir.h>. Not necessary, and
1642 doesn't exist on some systems.
1644 * infrun.c (wait_for_inferior!!!!): Prevent gdb from hanging when
1645 nexting over recursive function calls.
1647 * target.c (target_read_string): Create this routine to read null
1648 terminated strings from the target. It deals with running off the
1649 end of memory elegantly as well. solib.c (find_solib): Use
1650 target_read_string() to avoid problems with running off the end of
1653 * inflow.c (child_terminal_info): #ifdef TIOCPGRP around lines
1654 that reference pgrp_inferior.
1656 Mon Jan 13 14:57:11 1992 Per Bothner (bothner at cygnus.com)
1658 * tm-mips.h: Removed BLOCK_ADDRESS_ABSOLUTE, now that
1659 mips-tfile has been hacked to act more "traditionally."
1660 * dbxread.c: Fixed typo in comment.
1662 Sun Jan 12 13:08:36 1992 Per Bothner (bothner at cygnus.com)
1664 * mips-tdep.c (mips_skip_prologue): Add some number of
1665 'sw' instructions before 'addiu' adjusts the stack.
1667 Fri Jan 10 13:47:06 1992 Fred Fish (fnf at cygnus.com)
1669 * dwarfread.c (start_symtab, end_symtab, scopecount, openscope,
1670 freescope, buildblock closescope, record_line, add_symbol_to_list,
1671 gatherblocks, make_blockvector): Extensive changes to switch
1672 to generic symbol table building code in buildsym.c. Remove
1673 scope tree structures and functions, symbol table building
1674 functions, and lots of other small changes.
1676 * dwarfread.c: Add new macros GCC_PRODUCER and STREQN. Remove
1677 GCC_COMPILED_FLAG_SYMBOL and GCC2_COMPILED_FLAG_SYMBOL.
1679 Tue Jan 7 13:09:57 1992 Stu Grossman (grossman at cygnus.com)

1696 * Makefile.in: Change tm-svr4.h to tm-sysv4.h. Change xm-svr4.h
1697 to xm-sysv4.h. Split OPCODE_DIR into OPCODE_DIR1 and OPCODE_DIR2
1698 to reflect actual locations of opcode files, so TAGS target will
1701 * i386-tdep.c: Change an erroneous 'm68k' reference to 'i386'.
1703 * i386-tdep.c (supply_fpregset, fill_fpregset): Remove m68k
