330 * main.c (defined_command): Lower-case the user's
331 new command before entering it. Needed because
332 command lookup is case-insensitive (and also lower-cases).

430 * symfile.h (struct objfile): Removed, moved to objfiles.h.
431 * symfile.h, objfiles.h (allocate_objfile, free_objfile,
432 free_all_objfiles, iterate_over_objfiles, iterate_over_symtabs,
433 iterate_over_psymtabs, have_partial_symbols, have_full_symbols,
434 have_minimal_symbols): Prototypes moved to objfiles.h.
435 * symfile.h, objfiles.h (ALL_OBJFILES, ALL_OBJFILES_SAFE):
436 Macros moved to objfiles.h.
437 * tm-h8300.h, tm-i386v4.h (FRAME_CHAIN_VALID_ALTERNATE): Define.
439 Thu Mar 19 18:49:45 1992 Per Bothner (bothner@cygnus.com)
441 More C++ improvements (pointers to members, qualified names).
442 * c-exp.y: Support exp.type::name and exp->type::name
443 syntaxes. (Unfortunately, doesn't work for static members.)
444 * c-exp.y, eval.c: Make type::~type work better.
445 * eval.c (evaluate_subexp: OP_SCOPE): Replace use of
446 value_static_field by value_struct_elt_for_reference.
447 * eval.c (evaluate_subexp): Merge code for STRUCTOP_MEMBER
448 and STRUCTOP_MPTR; cast arg1 to domain-type of arg2.
449 * eval.c (evaluate_subexp): Remove special case for UNOP_ADDR
450 for OP_SCOPE operand; no point in it now that we use lazy
451 reading of values, and use "reference to member" objects.
452 * gdbtypes.h: Clarify comment.
453 * valops.c: Change value_struct_elt_for_address to return
454 a reference (or variable), rather than a pointer. Change
455 the name to value_struct_elt_for_reference to reflect this.
456 Returning a reference instead of a address provides a
457 generalization, since we can use the routine for both
458 class::name as well as &class::name.
459 Also, recurse to handle multiple inheritance properly.
460 * valprint.c: Moved code to print pointer-to-members
461 to new function point_class_member. This allows a
462 "reference-to-member" to be printed using the same code.
463 * valprint.c (type_print_varspec_prefix): Avoid printing
464 "struct " for domains of class-member types.
465 * valops.c (search_struct_field): Inline code for simplified
466 version of value_static_field (which can then be deleted).
467 * value.h: Rename value_struct_elt_for_address to
468 value_struct_elt_for_reference. Delete value_static_field.
469 * values.c: Remove no longer used function value_static_field.

478 elfread.c (xxx_symfile_new_init, xxx_symfile_init, xxx_symfile_read):
479 Pass pointer to struct objfile rather than pointer to sym_fns.
480 Change references inside each function accordingly. Allocate any
481 symbol file specific info in the per-objfile memory region.
482 * dbxread.c (free_and_init_header_files): Break function into
483 free_header_files(), called from dbx_symfile_finish(), and
484 init_header_files(), called from dbx_new_init().
485 * dbxread.c (dbx_new_init): Move deallocation things to new
486 dbx_symfile_finish function.
487 * elfread.c (elf_new_init): Call buildsym_new_init().
488 * objfiles.c (free_objfile): Call the appropriate symfile_finish()
489 routine for the objfile before deallocating other stuff.
490 * sparc-tdep.c (get_longjmp_target): Cast target_read_memory arg.
491 * symfile.h: Move struct sym_fns to before struct objfile def.
492 Add sym_finish function pointer and change prototypes of other
493 function pointers to reflect passing struct objfile pointer rather
494 than struct sym_fns pointer.
495 * symfile.c: Remove now obsolete symtab_fns pointer.
496 * symfile.c (symfile_init): Renamed to find_sym_fns, and now only
497 locates the correct sym_fns struct for the given objfile.
498 * symfile.c (syms_from_objfile, symbol_file_add): Restructured
499 for better support of mapped symbol tables.
500 * symfile.c (symbol_file_command): Remove obsolete code using
502 * symfile.h: Remove duplicate declarations for symfile_objfile,
503 entry_point, and object_files.
504 * target.c (target_info): Compare symfile_objfile to NULL.
505 * xcoffread.c (aixcoff_new_init): Move deallocation stuff to
506 aixcoff_symfile_finish().
508 Wed Mar 18 18:22:46 1992 Fred Fish (fnf@cygnus.com)
510 * infrun.c (IN_SOLIB_TRAMPOLINE): Add default definition.
511 * infrun.c (wait_for_inferior): Use IN_SOLIB_TRAMPOLINE.
512 * tm-sysv4.h (IN_SOLIB_TRAMPOLINE): Add SVR4 definition.
514 Wed Mar 18 15:51:15 1992 Per Bothner (bothner@cygnus.com)
516 Some improvements to g++ debugging.

518 * symtab.c: Other fixes to improve handing of operators.
519 * valprint.c (type_print_base): Fix test for constructor.
520 * values.c (value_static_field): Allow evaluation of
521 CLASS::METHOD, returning a function pointer.
523 Wed Mar 18 08:39:52 1992 Fred Fish (fnf@cygnus.com)
525 * Makefile.in (VERSION): Roll 4.4.6.
526 * exec.c (exec_file_command): Add code to ignore optional args
527 passed in by file_command() for use in symbol_file_command().
528 * main.c (main): Document -mapped and -readnow in help summary.
529 * objfiles.c (open_mapped_file): Cosmetic change, arg renamed.
530 * objfiles.c (allocate_objfile): Filename arg removed. Changes
531 to get filename from bfd with bfd_get_filename(). Test mapto
532 against 0, not NULL. Use mstrsave() to make copy of filename.
533 * remote-mm.c (mm_load): Symbol_file_add() takes an additional
535 * remote-vx.c (vx_load_command, add_symbol_stub):
536 Symbol_file_add() takes an additional arg.
537 * solib.c (symbol_add_stub): Symbol_file_add() takes an

542 * symfile.c (symbol_file_add): Takes an additional arg (readnow).
543 Change to eliminate local bfd and use symfile_bfd_open() plus
544 allocate_objfile(). Add code to implement readnow option.
545 * symfile.c (symbol_file_command): Changes to option handling,
546 readnow functionality moved to symbol_file_add().
547 * symfile.c (symfile_init): Eliminate local copy of bfd.

596 and using warning() instead of printfs.
597 * m2-exp.y: Define malloc to xmalloc and realloc to xrealloc.
598 * main.c (main): Add declaration for warning_pre_print and set it
599 similarly to error_pre_print. Add declarations for
600 mapped_symbol_files and readnow_symbol_files. Add appropriate
601 definitions to long_options[].
602 * minsyms.c: Trivial fix to comment.
603 * objfiles.c (allocate_objfile): Substantially rewritten for
604 using mapped symbol files.
605 * objfiles.c (throughout): Change from using per-objfile
606 xmalloc/xrealloc/free functions to xmmalloc/xmrealloc/mfree.

625 xmalloc/xrealloc/free functions to xmmalloc/xmrealloc/mfree.
626 * symtab.c (cplus_mangled_symbol): Cast return value to avoid
627 Sun compiler grumblings when PTR is char *.
628 * symtab.c (lookup_symbol): Cast return value of iterate_over_
629 msymbols() to correct pointer type.
630 * utils.c (warning_pre_print): Initialize to "\nwarning: ".
631 * utils.c (fatal, fatal_dump_core): Ensure that the fatal

651 * xcoffread.c: Only enable compilation of debugging functions
652 if IBM6000 is defined. Fails to compile otherwise.
654 Fri Mar 13 15:51:11 1992 K. Richard Pixley (rich@cygnus.com)
656 * Makefile.in: pass MAKEINFO down on info.
658 Fri Mar 13 12:56:36 1992 John Gilmore (gnu at cygnus.com)
660 * mipsread.c (mipscoff_symfile_read): Eliminate a lot of
661 useless code, including an lseek to an uninitialized variable.

666 Merged in patches from metin@ibmpa.awdpa.ibm.com (Metin G.
667 Ozisik) (dated Fri, 6 Mar 92 17:51) for the rs6000.
668 * minsyms.c, symfile.c: Changes that may be generally
669 applicable, but are #ifdef IBM6000 for now.
670 * rs6000-xdep.c: Fixed typo in comment.
671 * rs6000-tdep.c: Non-substatial changes.
672 * xoffread.c: The main change here is addition of some

679 to SOLIB_CREATE_INFERIOR_HOOK macro.
681 Sun Mar 8 21:17:48 1992 Fred Fish (fnf@cygnus.com)
683 * symfile.h: Add prototype for iterate_over_msymbols().
684 * symtab.c (cplus_mangled_symbol): Add function.
685 * symtab.c (lookup_symbol): Call cplus_mangled_symbol via
686 iterate_over_msymbols to find demangled C++ symbol.
687 * xcoffexec.c (relocate_minimal_symbol): Return meaningful
688 value to iterate_over_msymbols().

696 Thu Mar 5 23:56:01 1992 John Gilmore (gnu at cygnus.com)
698 * ecoff.c: Move to ../bfd/coff-msym.c.
699 * config/mt-*mips: Remove ecoff.o from the configuration.
700 * remote.c (): Add newline to initial +.
701 (remote_resume): Mention how to cope with signals.
702 (remote_interrupt): Add debug msg.
703 (remote-wait): Implement new 'T' reply, which includes
704 status, PC, and FP all in a single short message.
705 (putpkt): Add further debugging of packet acks.
706 * mipsread.c (fixup_symtab): Also swap RFD's.
707 (parse_partial_symbols): Avoid bug on unknown symbol types.
708 * Makefile.in (VERSION): Roll to 4.4.5.
709 * mips-tdep.c (heuristic_proc_start): Avoid long delays
710 for remote MIPS by limiting heuristic to 200 byte search.
711 (heuristic_proc_desc): Byte-swapping.
712 (mips_print_register): Cope with failure of
713 read_relative_register_raw_bytes. Byte-swap integers for

725 Wed Mar 4 11:56:42 1992 Fred Fish (fnf@cygnus.com)
727 * defs.h, utils.c: xrealloc takes PTR as first arg.
728 * defs.h: Reword confusing comment about ANSI prototypes.
729 * defs.h: Some minor whitespace changes.
730 * infrun.c (wait_for_inferior): Compare int tmp to int 0,
731 not NULL, which can be (void *).
732 * tm-amix.h, tm-i386v4.h: Add defines for setjmp/longjmp handling.
733 * tm-i386v.h (SP_ARG0): Define
734 * xm-sysv4.h: Back out of change for missing prototypes.
735 * i386-tdep.c (get_longjmp_target): Add function.
737 Wed Mar 4 05:46:11 1992 K. Richard Pixley (rich@rtl.cygnus.com)
739 * Makefile.in: install man page too.
741 Tue Mar 3 15:11:52 1992 Michael Tiemann (tiemann@cygnus.com)
743 * All GDB files that #include defs.h: Removed stdio.h.
744 (defs.h): #include stdio.h.
746 Mon Mar 2 23:00:12 1992 Steve Chamberlain (sac@thepub.cygnus.com)
748 * gdbtypes.c (lookup_pointer_type): initialize the TYPE_LENGTH of
749 a ptype to reflect the setting of TARGET_PTR_BIT. Set the

755 Sun Mar 1 17:41:09 1992 Per Bothner (bothner@cygnus.com)
757 * rs6000-xdep.c (frame_initial_stack_address): Move
758 code to set frame->cache_fsr into new separate function
759 frame_get_cacahe_fsr. This allows fixing a fatal error.
760 * xcoffexec.c: Turn previously suppressed error
761 message back on, after cleaning up BFD.
763 * breakpoint.c (breakpoint_re_set): Removed (at least for now)
764 printing of blank line, since it cases printing of an
765 extra blank line. Is this intended? It does mess up
767 * defs.h: Put back declarations of malloc and realloc,
768 but protected by #ifndef MALLOC_INCOMPATIBLE.
769 * objfiles.c: Undo previous change: Use malloc/realloc
770 for objfile malloc/realloc fields (but add a cast).
771 * xcoffexec.c: Suppress an error message (for now).
773 Sat Feb 29 14:43:02 1992 Per Bothner (bothner@cygnus.com)
775 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
776 [Mail dated Fri, 21 Feb 92 13:14:54 -0800]
777 * buildsym.c: Use smash_to_pointer_type() to handle forward type
779 * xcoffread.c: Modifications to C_DECL storage class handling, and
780 introduction of an old smash_to_pointer_type() routine.
782 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
783 [Mail dated Thu, 20 Feb 92 13:57:16 -0800]
784 * rs6000-xdep.c, rs6000-tdep.c, tm-rs6000.h: function_frame_info()
785 parameters have been modified.
787 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
788 [Mail dated Thu, 20 Feb 92 10:10:05 -0800]
789 * rs6000-tdep.c: Before Feb 5 92, register_valid[] array was not used,
790 and fetch_inferior_registers() always fetched all the registers
791 resulting valid register values at hand all the time. Pushing a dummy
792 frame did not require validating all register values first. After
793 putting the above mechanism into action, we didn't have valid registers
794 values always ready. Thus, all registers need to be fetched before
795 pushing a dummy frame now.
797 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
798 [Mail dated Thu, 13 Feb 92 16:22:44 -0800]
799 * rs6000-xdep.c: frame_initial_stack_address() function to calculate
800 the starting address (actual frame address) of a frame.
801 * rs6000-tdep.c: modifications to function_frame_info() to see if
802 function reserves a frame pointer register (alloca register)
803 * tm-rs6000.h: EXTRA_FRAME_INFO, FRAME_ARGS_ADDRESS and
804 FRAME_LOCALS_ADDRESS has been updated to support debugging of
805 functions with alloca() calls.
807 Sun Mar 1 13:13:39 1992 Fred Fish (fnf@cygnus.com)
809 * xm-sysv4.h: Provide definitions/prototypes for host environment
810 functions for which no definitions or prototypes are provided in
811 any currently included gdb or host environment header files.
812 For SVR4, this currently includes malloc and realloc, which cannot
813 be portably prototyped in any gdb include file.
815 Sat Feb 29 14:43:02 1992 Per Bothner (bothner@cygnus.com)
817 * buildsym.h: Remove obsolete variable file_stabs.
819 * Makefile.in: Move place where configure merges in host-
820 and target-dependent fragments later, so the latter
821 can override (say) GNU_MALLOC.
822 * config/mh-rs6000: Use system malloc. Otherwise, I
823 ended up with *two* incompatible versions of malloc
824 (functions in libc would call the malloc in libc).
825 I assume this is a shared library problem.
827 * remote.c: Fix (presumed) typo.
828 * objfiles.c: Use xmalloc/xrealloc instead of
829 malloc/realloc (since the latter are no longer declared).
831 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
832 [Mail dated Thu, 6 Feb 1992 10:22:02 -0800]
833 * rs6000-xdep.c: Improvements to fetch_inferior_registers() to
834 handle individual registers.
835 * tm-rs6000.h: Fix SAVED_PC_AFTER_CALL macro to handle pc value
836 correctly in case it wasn't cached yet. (A problem showed up
837 after fetching individual registers.)
838 * buildsym.c: Disable type_synonym_name's type name overwriting
839 in cases it is unnecesary. rs6000 portation doesn't use
840 type_synonym_name, and it used to nullify type names
841 * xcoffread.c: to handle g++'s typename abbreviation, fill in a
842 type's name as soon as space for that type is allocated.
843 * xcoffread.c: ignore a section's lineno information if it is
844 not `.text'. (In rs6000 bfd portation integration, skipping over
845 `.pad' sections are ignored since it was in machine independent
846 part of the code. Thus, a problem of fake sections with invalid
847 lineno information arised.)
849 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
850 [Mail dated Thu, 6 Feb 1992 13:26:22 -0800]
851 * rs6000-tdep.c: make function_frame_info() work whether or not
852 reading from a core file.
853 * tm-rs6000.h: Implementation of FRAME_FIND_SAVED_REGS macro.
855 * infrun.c. main.c, printcmd.c. symtab.c:
856 More changes from IBM for rs6000.
859 Thu Feb 27 22:57:19 1992 Per Bothner (bothner@cygnus.com)
861 * rs6k-opcode.h, tm-rs6000.h, xm-rs6000.h, rs6000-tdep.c,
862 rs6000-xdep.c, xcoffexec.c, xcoffread.c:
863 Merge in changes (mostly from IBM) for RS6000.
864 * breakpoint.c, buildsym.c, infptrace.c, stack.c, symtab.c:
865 More changes from IBM for RS6000. These are in machine-
866 independent code, and probably could do with some cleaning
867 up. The most questionable of these are #ifdef IBM6000.
868 * infrun.c, sparc-tdep.c: Pass a parameter (signal number)
869 to single_step() (for consistency with rs6000 and i860).
870 * utils.c: Allow the 1st arg to xrealloc to be NULL
871 (in which case do malloc). This removes the need for
872 some tests in xcoff code (and perhaps other places?).
873 * coffread.c: Removed variables last_source_file,
874 type_vector, and type_vector_length as these are now
875 defined by buildsym.[ch].
876 * defs.h: Remove prototypes for malloc and realloc, since
877 these should only be used to implement xmalloc and xrealloc,
878 and they conflict with <stdlib.h> in AIX - where they
879 return void* even when __STDC__ isn't defined. Sigh.
880 * munch: Recognize *initialize* in data as well as text
881 (AIX uses data). Also, incorporate a patch from Garrett
882 Wollman <wollman@uvm-gen.uvm.edu> to make the sed script
883 much more sensible, by only trying to match the name of
884 the initialize_foo function, and not the junk before it.
886 Thu Feb 27 20:07:43 1992 Stu Grossman (grossman at cygnus.com)
888 * breakpoint.c (breakpoint_re_set_one): Don't reset breakpoint
889 unless symbol table indicates that something has changed.

893 * remote.c: Make it work for embedded MIPS. Increase buffer
894 size, and use throughout. Round buffer size up if too many regs.
895 Support baud rate setting and try for an 8-bit path. If
896 interrupted while waiting for target, send a ^C down the wire.
897 Avoid single-byte reads.
898 * tm-mips.h: Add more embedded-system registers to REGISTER_NAMES
900 * mips-xdep.h: Avoid the embedded regs when on Unix.

903 routines from ecoff.c, to read a symbol table written in any
904 of the four possible byte orders.
905 * configure.in (mips-big-* target): Same as Sony News.

916 * (create_longjmp_breakpoint, breakpoint_re_set,
917 breakpoint_re_set_one, enable/disable_longjmp_breakpoint),
918 symfile.c (syms_from_objfile): Re-do
919 insertion of longjmp breakpoints. Move all code into
920 breakpoint_re_set, and call that instead of
921 create_longjmp_breakpoint in symfile.c.
923 Thu Feb 27 06:11:05 1992 John Gilmore (gnu at cygnus.com)
925 * breakpoint.h (ALL_BREAKPOINTS_SAFE): Add.

935 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)

938 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced

952 * breakpoint.h: Move prototypes to follow enum definition they need.
953 * breakpoint.c, infrun.c: Lint.
954 * printcmd.c: Use `enum enable' rather than `enum
956 * mipsread.c: First pass at making it compile with the new
957 objfile changes. Probably seriously broken still, but it
960 Sat Feb 22 00:56:39 1992 Stu Grossman (grossman at cygnus.com)

1338 value.h: Prototypes for static functions; lint.
1339 * gdbtypes.h: Empty file to ease transition.
1341 Thu Feb 20 16:43:13 1992 Fred Fish (fnf at cygnus.com)

1352 remote-hms.c, remote-mm.c, remote-nindy.c, remote-vx.c, remote.c,
1353 target.c, target.h, valarith.c, valops.c, value.h, xcoffexec.c:
1354 Remove to_call_function and target_call_function, since it
1355 always calls the same thing (call_function_by_hand).
1356 * core.c, exec.c, solib.c: Rename target_ops sections =>
1358 * infcmd.c, inflow.c, infptrace.c, infrun.c, main.c, target.c,
1359 target.h: target_kill takes no args.
1360 * language.c (language_info): Scaffolding to allow briefer
1361 messages when the current language changes. FIXME.
1362 * xm-amix.h, xm-i386v4.h, xm-stratus.h: Define NORETURN to avoid
1363 complaints about volatile functions.
1364 * xm-sysv4.h (HAVE_MMAP): Define.
1366 Thu Feb 20 09:04:18 1992 Fred Fish (fnf at cygnus.com)

1373 * ieee-float.h: Use PARAMS for prototypes; make some params const.
1374 * ieee-float.c, valarith.c: Include <stdio.h>. Lint. b*=>mem*.
1375 * m2-exp.y: Remove unused CONST; Rename OR and AND.
1376 * utils.c: Avoid declaring malloc and realloc. Lint.

1379 Mon Feb 17 07:13:27 1992 Fred Fish (fnf at cygnus.com)
1381 * dwarfread.c (process_dies): Add case to handle TAG_pointer_type
1382 DIE's. Add new function read_tag_pointer_type() to read them.
1384 * dwarfread.c (dwarf_read_array_type, read_subroutine_type):
1385 When creating a new user defined type, check to see if a partial
1386 type already exists, and if so, bash it to fit.
1388 Fri Feb 14 19:00:17 1992 John Gilmore (gnu at cygnus.com)
1390 * coffread.c (decode_base_type): Pass long, not union.
1391 Fix by Eric Valette, ev@chorus.fr.
1393 Thu Feb 13 17:14:28 1992 Fred Fish (fnf at cygnus.com)
1395 * elfread.c (elf_symtab_read): Fix code to correctly track
1396 changes in bfd for absolute symbols.
1398 Thu Feb 13 12:43:29 1992 Stu Grossman (grossman at cygnus.com)
1400 * xm-vaxbsd.h: Close off comment.
1402 Thu Feb 13 07:45:19 1992 Fred Fish (fnf at cygnus.com)
1404 * xm-sysv4.h: Define NEED_POSIX_SETPGID.
1406 Fri Feb 7 11:51:12 1992 Per Bothner (bothner at cygnus.com)
1408 * mips-tdep.c (mips_print_registers): Print correct register
1409 number for double pseudo-registers.
1411 Fri Feb 7 07:56:05 1992 John Gilmore (gnu at cygnus.com)
1413 * buildsym.c (read_struct_type): Avoid double-bump of parse ptr
1414 in the op$::OPERATOR. case. From Steven McCanne,
1415 <mccanne@horse.ee.lbl.gov>.
1417 * exec.c (set_section_name): Pass arg to exec_files_info;
1418 only call it if interactive. From Francis Kauth <fk@tv.tv.tek.com>.
1420 Thu Feb 6 17:41:32 1992 John Gilmore (gnu at cygnus.com)
1422 * main.c (print_gdb_version): Copyright msg: only this year.
1423 (cd_command): Avoid changing current_directory on error.
1425 Thu Feb 6 15:14:01 1992 Per Bothner (bothner at cygnus.com)
1427 * mipsread.c (parse_partial_symbols): Handle dependencies
1428 between partial symbol tables (when not doing stabs-in-ecoff).
1429 (This used to be handled by parse_fdr, but parse_fdr was
1430 incompatible with handling stabs-in-ecoff, so the code
1431 was re-written to not use parse_fdr. Unfortunately,
1432 the logic to handle dependencies was overlooked.)
1434 Thu Feb 6 11:51:39 1992 Steve Chamberlain (sac at rtl.cygnus.com)
1436 * coffread.c (read_enum_type): Use the size of a target int when
1438 * defs.h: added new #define for TARGET_PTR_BIT, defaults to size
1440 * h8300-tdep.c, remote-hms.c, tm-h8300.h: too many changes to count
1441 * symtab.c (lookup_reference_type, lookup_ptr_type): use
1442 TARGET_PTR_BIT to determine size of a pointer
1443 * values.c (unpack_long): when unpacking a REF or a PTR don't
1444 assume the size of the type.
1446 Wed Feb 5 22:29:59 1992 John Gilmore (gnu at cygnus.com)
1448 * mipsread.c (parse_symbol): Avoid clobbering enum pointer when
1449 looking at its members. Improve guess between struct and union,
1450 only assuming union if multiple members have offsets of zero.
1452 Tue Feb 4 18:05:44 1992 Per Bothner (bothner at cygnus.com)
1454 * mipsread.c: Use (FP0_REGNUM-32) instead of magic number 6.
1455 (This is just for clarity - and one day permitting us to
1456 change FP0_REGNUM from 38 to 32, which would make more sense.)
1457 * tm-mips.h: Added STAB_REG_TO_REGNUM macro, so that
1458 register numbers in stabs-in-ecoff get handled correctly.
1460 Sat Feb 1 04:45:10 1992 Stu Grossman (grossman at cygnus.com)
1462 * xm-vax.h, xm-vaxult.h, xm-vaxbsd.h, config/mh-vaxult,
1463 config/mh-vaxbsd, configure.in: Split up config stuff for Vaxen
1464 into BSD and Ultrix.
1466 Sat Feb 1 04:39:41 1992 John Gilmore (gnu at cygnus.com)
1468 * dbxread.c (dbx_symfile_init): Call malloc, not xmalloc.
1470 Sat Feb 1 04:15:41 1992 Stu Grossman (grossman at cygnus.com)
1472 * Makefile.in: Increment version to 4.4.1.
1473 * main.c (print_gdb_version): Update copyright notice.
1475 Sat Feb 1 01:43:11 1992 Per Bothner (bothner at cygnus.com)
1477 * mipsread.c: Prepend "struct " to the names of structure
1478 types, and similarly for enums and unions. (This used
1479 to be done, but got lost in the re-write to "guess" the
1480 difference between enum/struct/union.)
1481 Also, guess that a tag is an enum if the first member
1484 Fri Jan 31 21:45:51 1992 Stu Grossman (grossman at cygnus.com)
1486 * xm-vax.h: #ifndef ultrix around #include of endian.h and
1489 Fri Jan 31 00:05:01 1992 John Gilmore (gnu at cygnus.com)
1491 * Projects: Patching executables is done.
1492 * Makefile.in (VERSION): Roll to gdb-4.4.
1493 * README, WHATS.NEW: Update for gdb-4.4.
1495 * symfile.c (reread_symbols): Whenever we reread one object
1496 file's symbols, we must restart the scan, because the object_files
1497 chain has been permuted.
1499 * exec.c (exec_files_info): Split out into print_section_info.
1500 Print BFD filename of each section if it's not the default one.
1501 * core.c (core_files_info): Call print_section_info.
1503 * xm-vax.h: Include a few system header files whose definitions
1504 must precede defs.h.
1505 * language.c, language.h: Make some things const.
1506 * expression.h, main.c: const spreads like ooze.
1508 * mem-break.c (break_insn, break_insn_size): Use unsigned chars,
1509 since BREAKPOINT values can be >0x80.
1511 Thu Jan 30 17:21:14 1992 Stu Grossman (grossman at cygnus.com)
1513 * infrun.c, xm-i386sco.h: SCO needs to use setpgid().
1515 Thu Jan 30 01:04:23 1992 John Gilmore (gnu at cygnus.com)
1517 * sparc-pinsn.c: Remove kludge for preferring architectures.
1518 Remove #ifdef's for SORT_NEEDED. We need to sort the table, now
1519 and forever. Add `add' instruction to the set that get checked
1520 for a preceding `sethi' in order to print an absolute address.
1521 Corresponding changes in ../include/opcode/sparc.h needed
1522 to eliminate garbage instructions.
1524 Wed Jan 29 19:24:34 1992 Per Bothner (bothner at cygnus.com)
1526 * mipsread.c (parse_partial_symbols): Make sure partial
1527 symbols are created for external symbols (as used to be
1528 the case). This is a bit of a pain with the mips-coff.
1529 It uses a table which points to all of the external
1530 symbols belonging to a particular FDR or psymtab.
1531 Once we've generated this table, we might as well save
1532 it, and then use it in psymtab_to_symtab_1 to find
1533 the symbols to pass to parse_external().
1534 * symfile.c, symfile.c: New function start_psymtab_common
1535 to share the common parts of allocating a new psymtab
1536 for dbxread, mipsread (and later dwarfread). Its code
1537 was pulled out from start_psymtab in dbxread.c.
1538 * dbxread.c (start_psymtab): Use start_psymtab_common().
1540 * valprint.c (val_print): If there is an error when trying
1541 to print a string, check to see if there really is a problem
1542 by reading just one character. If that works, assume
1545 Wed Jan 29 18:58:43 1992 Stu Grossman (grossman at cygnus.com)
1547 * sparc-pinsn.c (compare_opcodes): Make it prefer v6, v7,
1548 cypress, v8 mnemonics in that order.
1550 Tue Jan 28 17:32:13 1992 Per Bothner (bothner at cygnus.com)
1552 * sparc-pinsn.c: Put the qsort() back in.
1554 Mon Jan 27 18:51:03 1992 John Gilmore (gnu at cygnus.com)
1556 * findvar.c (read_register, write_register): Handle machines
1557 where REGISTER_TYPE is not the same size as "int".
1559 Handle debug symbols in dynamically loaded (relocated) code:
1561 * dbxread.c (read_ofile_symtab): Fix up N_CATCH better. Pass
1562 offset to process_one_symbol.
1563 (process_one_symbol): Take new offset parameter. Add it into
1564 appropriate symbol types to relocate symbols to loaded addresses.
1565 Handle all possible symbol types, and complain() about types that
1566 we don't expect to see.
1567 * mipsread.c (psymtab_to_symtab_1): Pass offset of zero to
1568 process_one_symbol (FIXME, should pass real offset).
1572 * breakpoint.c (resolve_sal_pc): Split out code to resolve a
1574 (set_breakpoint, break_command_1, until_break_command,
1575 catch_command_1, breakpoint_re_set_one): Use it.
1576 * symtab.h (resolve_sal_pc): Declare.
1577 * infcmd.c (jump_command): Use resolve_sal_pc.
1579 * source.c (list_command): Shorten "FILE, line N" to "FILE:N".
1581 * putenv.c (putenv): Avoid unportably casting pointers to unsigneds.
1583 * c-exp.y (yylex): `this' and `template' are only tokens in C++.
1585 * xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
1586 xm-np1.h, xm-pn.h, xm-pyr.h, xm-rtbsd.h, xm-symmetry.h, xm-umax.h:
1587 Remove MISSING_VPRINTF declaration, and superfluous "kgdb" defines.
1589 Mon Jan 27 15:46:21 1992 Stu Grossman (grossman at cygnus.com)
1591 * dbxread.c (process_one_symbol): Make a first cut at handling
1592 symbol tables generated by Sun's acc. (#ifdef'd out, FIXME.)
1594 * symtab.c (find_pc_line): Fix stepping into and out of #included
1597 Mon Jan 27 13:00:55 1992 Stu Grossman (grossman at cygnus.com)
1599 * Makefile.in (OPCODES): Remove OPCODES defs and refs. There is
1600 no longer any need to copy ../include/opcode/* into gdb.
1602 Mon Jan 27 12:30:38 1992 John Gilmore (gnu at cygnus.com)
1604 * ChangeLog, ChangeLog-9091: Split ChangeLog at 1992.
1606 Sun Jan 26 19:05:40 1992 Per Bothner (bothner at cygnus.com)
1608 * valprint.c (type_print_base, type_print_method_args):
1609 Print C++ constructor methods without bogus "return type."
1611 Sat Jan 25 15:57:59 1992 Fred Fish (fnf at cygnus.com)
1613 * infptrace.c (child_xfer_memory): Parameter "target" should
1614 be a pointer to a structure, not the entire structure.
1616 Fri Jan 24 01:30:27 1992 Fred Fish (fnf at cygnus.com)
1618 * depend: Convert the couple of references to ansidecl.h that
1619 used the local gdb version to use the ../include version.
1621 Thu Jan 23 22:24:43 1992 Fred Fish (fnf at cygnus.com)
1624 (child_xfer_memory): Takes pointer to a struct, not entire struct.
1625 (inferior_proc_init): Fix non-ANSI version of args.
1626 (attach): Call print_sys_errmsg with correct number of args.
1627 (mappingflags): Make static, does not need to be global.
1629 * i386-tdep.c (i386_frame_num_args): Takes a pointer to a struct
1630 not the entire struct itself.
1632 * valops.c (value_assign): Cast some args to modify_field() and
1633 {read,write}_register_bytes() correctly.
1635 * ansidecl.h: Removed, is duplicate of ../include/ansidecl.h
1637 * Makefile.in (MALLOCSRC): Removed reference to removed local
1640 * dwarfread.c (list_in_scope): Needs an initial value, use file
1643 Mon Jan 20 19:06:28 1992 Stu Grossman (grossman at cygnus.com)
1645 * main.c (main): Make option_index local to keep new getopt happy.
1646 main.c, solib.c, Makefile.in: Update copyright notices.
1648 Mon Jan 20 08:54:00 1992 Michael Tiemann (tiemann at cygnus.com)
1650 * cplus-dem.c (cplus_demangle): Correctly demangle destructors.
1652 Sat Jan 18 17:17:45 1992 Stu Grossman (grossman at cygnus.com)
1654 * Makefile.in (HFILES): Add partial-stab.h.
1656 Sat Jan 18 16:45:01 1992 Fred Fish (fnf at cygnus.com)
1658 * config/mh-stratus, config/mt-stratus, tm-stratus.h, xm-stratus.h:
1659 New files for stratus. Not complete enough to actually build
1660 on the Stratus machine; that awaits copyright assignment for
1663 * Makefile.in (USER_CFLAGS): Add macro specifically reserved
1664 for getting custom flags into CFLAGS when doing makes.
1666 * configure.in: Add config information for stratus.
1668 Thu Jan 16 00:51:46 1992 Fred Fish (fnf at cygnus.com)
1670 * dbxread.c (process_one_symbol): Pass address of structure
1671 to complain(), rather than the whole structure.

1681 values that are computed off a base register.
1683 * dwarfread.c (new_symbol): Rework TAG_global_variable and
1684 TAG_local_variable cases to account for static variables
1685 within function scopes.
1687 Tue Jan 14 12:28:52 1992 Stu Grossman (grossman at cygnus.com)
1689 * inflow.c: remove #include <sys/dir.h>. Not necessary, and
1690 doesn't exist on some systems.
1692 * infrun.c (wait_for_inferior!!!!): Prevent gdb from hanging when
1693 nexting over recursive function calls.
1695 * target.c (target_read_string): Create this routine to read null
