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

428 More C++ improvements (pointers to members, qualified names).
429 * c-exp.y: Support exp.type::name and exp->type::name
430 syntaxes. (Unfortunately, doesn't work for static members.)
431 * c-exp.y, eval.c: Make type::~type work better.
432 * eval.c (evaluate_subexp: OP_SCOPE): Replace use of
433 value_static_field by value_struct_elt_for_reference.
434 * eval.c (evaluate_subexp): Merge code for STRUCTOP_MEMBER
435 and STRUCTOP_MPTR; cast arg1 to domain-type of arg2.
436 * eval.c (evaluate_subexp): Remove special case for UNOP_ADDR
437 for OP_SCOPE operand; no point in it now that we use lazy
438 reading of values, and use "reference to member" objects.
439 * gdbtypes.h: Clarify comment.
440 * valops.c: Change value_struct_elt_for_address to return
441 a reference (or variable), rather than a pointer. Change
442 the name to value_struct_elt_for_reference to reflect this.
443 Returning a reference instead of a address provides a
444 generalization, since we can use the routine for both
445 class::name as well as &class::name.
446 Also, recurse to handle multiple inheritance properly.
447 * valprint.c: Moved code to print pointer-to-members
448 to new function point_class_member. This allows a
449 "reference-to-member" to be printed using the same code.
450 * valprint.c (type_print_varspec_prefix): Avoid printing
451 "struct " for domains of class-member types.
452 * valops.c (search_struct_field): Inline code for simplified
453 version of value_static_field (which can then be deleted).
454 * value.h: Rename value_struct_elt_for_address to
455 value_struct_elt_for_reference. Delete value_static_field.
456 * values.c: Remove no longer used function value_static_field.

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

505 * symtab.c: Other fixes to improve handing of operators.
506 * valprint.c (type_print_base): Fix test for constructor.
507 * values.c (value_static_field): Allow evaluation of
508 CLASS::METHOD, returning a function pointer.
510 Wed Mar 18 08:39:52 1992 Fred Fish (fnf@cygnus.com)
512 * Makefile.in (VERSION): Roll 4.4.6.
513 * exec.c (exec_file_command): Add code to ignore optional args
514 passed in by file_command() for use in symbol_file_command().

532 * symfile.c (symbol_file_command): Changes to option handling,
533 readnow functionality moved to symbol_file_add().
534 * symfile.c (symfile_init): Eliminate local copy of bfd.

583 and using warning() instead of printfs.
584 * m2-exp.y: Define malloc to xmalloc and realloc to xrealloc.
585 * main.c (main): Add declaration for warning_pre_print and set it
586 similarly to error_pre_print. Add declarations for
587 mapped_symbol_files and readnow_symbol_files. Add appropriate
588 definitions to long_options[].
589 * minsyms.c: Trivial fix to comment.
590 * objfiles.c (allocate_objfile): Substantially rewritten for
591 using mapped symbol files.
592 * objfiles.c (throughout): Change from using per-objfile
593 xmalloc/xrealloc/free functions to xmmalloc/xmrealloc/mfree.

612 xmalloc/xrealloc/free functions to xmmalloc/xmrealloc/mfree.
613 * symtab.c (cplus_mangled_symbol): Cast return value to avoid
614 Sun compiler grumblings when PTR is char *.
615 * symtab.c (lookup_symbol): Cast return value of iterate_over_
616 msymbols() to correct pointer type.
617 * utils.c (warning_pre_print): Initialize to "\nwarning: ".
618 * utils.c (fatal, fatal_dump_core): Ensure that the fatal

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

653 Merged in patches from metin@ibmpa.awdpa.ibm.com (Metin G.
654 Ozisik) (dated Fri, 6 Mar 92 17:51) for the rs6000.
655 * minsyms.c, symfile.c: Changes that may be generally
656 applicable, but are #ifdef IBM6000 for now.
657 * rs6000-xdep.c: Fixed typo in comment.
658 * rs6000-tdep.c: Non-substatial changes.
659 * xoffread.c: The main change here is addition of some
661 * xoffexec.c: More changes.
663 * xcoffread.c: Fixed two too-few-parameters bugs.
665 * solib.h, infrun.c, tm-rs6000.h: Add a PID parameter
666 to SOLIB_CREATE_INFERIOR_HOOK macro.
668 Sun Mar 8 21:17:48 1992 Fred Fish (fnf@cygnus.com)
670 * symfile.h: Add prototype for iterate_over_msymbols().
671 * symtab.c (cplus_mangled_symbol): Add function.
672 * symtab.c (lookup_symbol): Call cplus_mangled_symbol via
673 iterate_over_msymbols to find demangled C++ symbol.
674 * xcoffexec.c (relocate_minimal_symbol): Return meaningful
675 value to iterate_over_msymbols().

681 * Makefile.in: added check target.
683 Thu Mar 5 23:56:01 1992 John Gilmore (gnu at cygnus.com)
685 * ecoff.c: Move to ../bfd/coff-msym.c.
686 * config/mt-*mips: Remove ecoff.o from the configuration.
687 * remote.c (): Add newline to initial +.
688 (remote_resume): Mention how to cope with signals.
689 (remote_interrupt): Add debug msg.
690 (remote-wait): Implement new 'T' reply, which includes
691 status, PC, and FP all in a single short message.
692 (putpkt): Add further debugging of packet acks.
693 * mipsread.c (fixup_symtab): Also swap RFD's.
694 (parse_partial_symbols): Avoid bug on unknown symbol types.
695 * Makefile.in (VERSION): Roll to 4.4.5.
696 * mips-tdep.c (heuristic_proc_start): Avoid long delays
697 for remote MIPS by limiting heuristic to 200 byte search.
698 (heuristic_proc_desc): Byte-swapping.
699 (mips_print_register): Cope with failure of
700 read_relative_register_raw_bytes. Byte-swap integers for

704 Thu Mar 5 12:32:09 1992 Stu Grossman (grossman at cygnus.com)
706 * config.sub configure.in config/.Sanitize config/mh-irix4
707 gdb/.Sanitize gdb/configure.in gdb/mips-tdep.c gdb/mipsread.c

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

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

905 symfile.c (syms_from_objfile): Re-do
906 insertion of longjmp breakpoints. Move all code into

1325 value.h: Prototypes for static functions; lint.
1326 * gdbtypes.h: Empty file to ease transition.
1328 Thu Feb 20 16:43:13 1992 Fred Fish (fnf at cygnus.com)

1340 target.c, target.h, valarith.c, valops.c, value.h, xcoffexec.c:
1341 Remove to_call_function and target_call_function, since it
1342 always calls the same thing (call_function_by_hand).
1343 * core.c, exec.c, solib.c: Rename target_ops sections =>
1345 * infcmd.c, inflow.c, infptrace.c, infrun.c, main.c, target.c,
1346 target.h: target_kill takes no args.
1347 * language.c (language_info): Scaffolding to allow briefer
1348 messages when the current language changes. FIXME.
1349 * xm-amix.h, xm-i386v4.h, xm-stratus.h: Define NORETURN to avoid
1350 complaints about volatile functions.
1351 * xm-sysv4.h (HAVE_MMAP): Define.
1353 Thu Feb 20 09:04:18 1992 Fred Fish (fnf at cygnus.com)
1355 * defs.h: Include ansidecl.h and PARAMS macro. Use PARAMS

1360 * ieee-float.h: Use PARAMS for prototypes; make some params const.
1361 * ieee-float.c, valarith.c: Include <stdio.h>. Lint. b*=>mem*.
1362 * m2-exp.y: Remove unused CONST; Rename OR and AND.
1363 * utils.c: Avoid declaring malloc and realloc. Lint.

1366 Mon Feb 17 07:13:27 1992 Fred Fish (fnf at cygnus.com)
1368 * dwarfread.c (process_dies): Add case to handle TAG_pointer_type
1369 DIE's. Add new function read_tag_pointer_type() to read them.
1371 * dwarfread.c (dwarf_read_array_type, read_subroutine_type):
1372 When creating a new user defined type, check to see if a partial
1373 type already exists, and if so, bash it to fit.
1375 Fri Feb 14 19:00:17 1992 John Gilmore (gnu at cygnus.com)
1377 * coffread.c (decode_base_type): Pass long, not union.
1378 Fix by Eric Valette, ev@chorus.fr.
1380 Thu Feb 13 17:14:28 1992 Fred Fish (fnf at cygnus.com)
1382 * elfread.c (elf_symtab_read): Fix code to correctly track
1383 changes in bfd for absolute symbols.
1385 Thu Feb 13 12:43:29 1992 Stu Grossman (grossman at cygnus.com)
1387 * xm-vaxbsd.h: Close off comment.
1389 Thu Feb 13 07:45:19 1992 Fred Fish (fnf at cygnus.com)
1391 * xm-sysv4.h: Define NEED_POSIX_SETPGID.
1393 Fri Feb 7 11:51:12 1992 Per Bothner (bothner at cygnus.com)
1395 * mips-tdep.c (mips_print_registers): Print correct register
1396 number for double pseudo-registers.
1398 Fri Feb 7 07:56:05 1992 John Gilmore (gnu at cygnus.com)
1400 * buildsym.c (read_struct_type): Avoid double-bump of parse ptr
1401 in the op$::OPERATOR. case. From Steven McCanne,
1402 <mccanne@horse.ee.lbl.gov>.
1404 * exec.c (set_section_name): Pass arg to exec_files_info;
1405 only call it if interactive. From Francis Kauth <fk@tv.tv.tek.com>.
1407 Thu Feb 6 17:41:32 1992 John Gilmore (gnu at cygnus.com)
1409 * main.c (print_gdb_version): Copyright msg: only this year.
1410 (cd_command): Avoid changing current_directory on error.
1412 Thu Feb 6 15:14:01 1992 Per Bothner (bothner at cygnus.com)
1414 * mipsread.c (parse_partial_symbols): Handle dependencies
1415 between partial symbol tables (when not doing stabs-in-ecoff).
1416 (This used to be handled by parse_fdr, but parse_fdr was
1417 incompatible with handling stabs-in-ecoff, so the code
1418 was re-written to not use parse_fdr. Unfortunately,
1419 the logic to handle dependencies was overlooked.)
1421 Thu Feb 6 11:51:39 1992 Steve Chamberlain (sac at rtl.cygnus.com)
1423 * coffread.c (read_enum_type): Use the size of a target int when
1425 * defs.h: added new #define for TARGET_PTR_BIT, defaults to size
1427 * h8300-tdep.c, remote-hms.c, tm-h8300.h: too many changes to count
1428 * symtab.c (lookup_reference_type, lookup_ptr_type): use
1429 TARGET_PTR_BIT to determine size of a pointer
1430 * values.c (unpack_long): when unpacking a REF or a PTR don't
1431 assume the size of the type.
1433 Wed Feb 5 22:29:59 1992 John Gilmore (gnu at cygnus.com)
1435 * mipsread.c (parse_symbol): Avoid clobbering enum pointer when
1436 looking at its members. Improve guess between struct and union,
1437 only assuming union if multiple members have offsets of zero.
1439 Tue Feb 4 18:05:44 1992 Per Bothner (bothner at cygnus.com)
1441 * mipsread.c: Use (FP0_REGNUM-32) instead of magic number 6.
1442 (This is just for clarity - and one day permitting us to
1443 change FP0_REGNUM from 38 to 32, which would make more sense.)
1444 * tm-mips.h: Added STAB_REG_TO_REGNUM macro, so that
1445 register numbers in stabs-in-ecoff get handled correctly.
1447 Sat Feb 1 04:45:10 1992 Stu Grossman (grossman at cygnus.com)
1449 * xm-vax.h, xm-vaxult.h, xm-vaxbsd.h, config/mh-vaxult,
1450 config/mh-vaxbsd, configure.in: Split up config stuff for Vaxen
1451 into BSD and Ultrix.
1453 Sat Feb 1 04:39:41 1992 John Gilmore (gnu at cygnus.com)
1455 * dbxread.c (dbx_symfile_init): Call malloc, not xmalloc.
1457 Sat Feb 1 04:15:41 1992 Stu Grossman (grossman at cygnus.com)
1459 * Makefile.in: Increment version to 4.4.1.
1460 * main.c (print_gdb_version): Update copyright notice.
1462 Sat Feb 1 01:43:11 1992 Per Bothner (bothner at cygnus.com)
1464 * mipsread.c: Prepend "struct " to the names of structure
1465 types, and similarly for enums and unions. (This used
1466 to be done, but got lost in the re-write to "guess" the
1467 difference between enum/struct/union.)
1468 Also, guess that a tag is an enum if the first member
1471 Fri Jan 31 21:45:51 1992 Stu Grossman (grossman at cygnus.com)
1473 * xm-vax.h: #ifndef ultrix around #include of endian.h and
1476 Fri Jan 31 00:05:01 1992 John Gilmore (gnu at cygnus.com)
1478 * Projects: Patching executables is done.
1479 * Makefile.in (VERSION): Roll to gdb-4.4.
1480 * README, WHATS.NEW: Update for gdb-4.4.
1482 * symfile.c (reread_symbols): Whenever we reread one object
1483 file's symbols, we must restart the scan, because the object_files
1484 chain has been permuted.
1486 * exec.c (exec_files_info): Split out into print_section_info.
1487 Print BFD filename of each section if it's not the default one.
1488 * core.c (core_files_info): Call print_section_info.
1490 * xm-vax.h: Include a few system header files whose definitions
1491 must precede defs.h.
1492 * language.c, language.h: Make some things const.
1493 * expression.h, main.c: const spreads like ooze.
1495 * mem-break.c (break_insn, break_insn_size): Use unsigned chars,
1496 since BREAKPOINT values can be >0x80.
1498 Thu Jan 30 17:21:14 1992 Stu Grossman (grossman at cygnus.com)
1500 * infrun.c, xm-i386sco.h: SCO needs to use setpgid().
1502 Thu Jan 30 01:04:23 1992 John Gilmore (gnu at cygnus.com)
1504 * sparc-pinsn.c: Remove kludge for preferring architectures.
1505 Remove #ifdef's for SORT_NEEDED. We need to sort the table, now
1506 and forever. Add `add' instruction to the set that get checked
1507 for a preceding `sethi' in order to print an absolute address.
1508 Corresponding changes in ../include/opcode/sparc.h needed
1509 to eliminate garbage instructions.
1511 Wed Jan 29 19:24:34 1992 Per Bothner (bothner at cygnus.com)
1513 * mipsread.c (parse_partial_symbols): Make sure partial
1514 symbols are created for external symbols (as used to be
1515 the case). This is a bit of a pain with the mips-coff.
1516 It uses a table which points to all of the external
1517 symbols belonging to a particular FDR or psymtab.
1518 Once we've generated this table, we might as well save
1519 it, and then use it in psymtab_to_symtab_1 to find
1520 the symbols to pass to parse_external().
1521 * symfile.c, symfile.c: New function start_psymtab_common
1522 to share the common parts of allocating a new psymtab
1523 for dbxread, mipsread (and later dwarfread). Its code
1524 was pulled out from start_psymtab in dbxread.c.
1525 * dbxread.c (start_psymtab): Use start_psymtab_common().
1527 * valprint.c (val_print): If there is an error when trying
1528 to print a string, check to see if there really is a problem
1529 by reading just one character. If that works, assume
1532 Wed Jan 29 18:58:43 1992 Stu Grossman (grossman at cygnus.com)
1534 * sparc-pinsn.c (compare_opcodes): Make it prefer v6, v7,
1535 cypress, v8 mnemonics in that order.
1537 Tue Jan 28 17:32:13 1992 Per Bothner (bothner at cygnus.com)
1539 * sparc-pinsn.c: Put the qsort() back in.
1541 Mon Jan 27 18:51:03 1992 John Gilmore (gnu at cygnus.com)
1543 * findvar.c (read_register, write_register): Handle machines
1544 where REGISTER_TYPE is not the same size as "int".
1546 Handle debug symbols in dynamically loaded (relocated) code:
1548 * dbxread.c (read_ofile_symtab): Fix up N_CATCH better. Pass
1549 offset to process_one_symbol.
1550 (process_one_symbol): Take new offset parameter. Add it into
1551 appropriate symbol types to relocate symbols to loaded addresses.
1552 Handle all possible symbol types, and complain() about types that
1553 we don't expect to see.
1554 * mipsread.c (psymtab_to_symtab_1): Pass offset of zero to
1555 process_one_symbol (FIXME, should pass real offset).
1559 * breakpoint.c (resolve_sal_pc): Split out code to resolve a
1561 (set_breakpoint, break_command_1, until_break_command,
1562 catch_command_1, breakpoint_re_set_one): Use it.
1563 * symtab.h (resolve_sal_pc): Declare.
1564 * infcmd.c (jump_command): Use resolve_sal_pc.
1566 * source.c (list_command): Shorten "FILE, line N" to "FILE:N".
1568 * putenv.c (putenv): Avoid unportably casting pointers to unsigneds.
1570 * c-exp.y (yylex): `this' and `template' are only tokens in C++.
1572 * xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
1573 xm-np1.h, xm-pn.h, xm-pyr.h, xm-rtbsd.h, xm-symmetry.h, xm-umax.h:
1574 Remove MISSING_VPRINTF declaration, and superfluous "kgdb" defines.
1576 Mon Jan 27 15:46:21 1992 Stu Grossman (grossman at cygnus.com)
1578 * dbxread.c (process_one_symbol): Make a first cut at handling
1579 symbol tables generated by Sun's acc. (#ifdef'd out, FIXME.)
1581 * symtab.c (find_pc_line): Fix stepping into and out of #included
1584 Mon Jan 27 13:00:55 1992 Stu Grossman (grossman at cygnus.com)
1586 * Makefile.in (OPCODES): Remove OPCODES defs and refs. There is
1587 no longer any need to copy ../include/opcode/* into gdb.
1589 Mon Jan 27 12:30:38 1992 John Gilmore (gnu at cygnus.com)
1591 * ChangeLog, ChangeLog-9091: Split ChangeLog at 1992.
1593 Sun Jan 26 19:05:40 1992 Per Bothner (bothner at cygnus.com)
1595 * valprint.c (type_print_base, type_print_method_args):
1596 Print C++ constructor methods without bogus "return type."
1598 Sat Jan 25 15:57:59 1992 Fred Fish (fnf at cygnus.com)
1600 * infptrace.c (child_xfer_memory): Parameter "target" should
1601 be a pointer to a structure, not the entire structure.
1603 Fri Jan 24 01:30:27 1992 Fred Fish (fnf at cygnus.com)
1605 * depend: Convert the couple of references to ansidecl.h that
1606 used the local gdb version to use the ../include version.
1608 Thu Jan 23 22:24:43 1992 Fred Fish (fnf at cygnus.com)
1611 (child_xfer_memory): Takes pointer to a struct, not entire struct.
1612 (inferior_proc_init): Fix non-ANSI version of args.
1613 (attach): Call print_sys_errmsg with correct number of args.
1614 (mappingflags): Make static, does not need to be global.
1616 * i386-tdep.c (i386_frame_num_args): Takes a pointer to a struct
1617 not the entire struct itself.
1619 * valops.c (value_assign): Cast some args to modify_field() and
1620 {read,write}_register_bytes() correctly.
1622 * ansidecl.h: Removed, is duplicate of ../include/ansidecl.h
1624 * Makefile.in (MALLOCSRC): Removed reference to removed local
1627 * dwarfread.c (list_in_scope): Needs an initial value, use file
1630 Mon Jan 20 19:06:28 1992 Stu Grossman (grossman at cygnus.com)
1632 * main.c (main): Make option_index local to keep new getopt happy.
1633 main.c, solib.c, Makefile.in: Update copyright notices.
1635 Mon Jan 20 08:54:00 1992 Michael Tiemann (tiemann at cygnus.com)
1637 * cplus-dem.c (cplus_demangle): Correctly demangle destructors.
1639 Sat Jan 18 17:17:45 1992 Stu Grossman (grossman at cygnus.com)
1641 * Makefile.in (HFILES): Add partial-stab.h.
1643 Sat Jan 18 16:45:01 1992 Fred Fish (fnf at cygnus.com)
1645 * config/mh-stratus, config/mt-stratus, tm-stratus.h, xm-stratus.h:
1646 New files for stratus. Not complete enough to actually build
1647 on the Stratus machine; that awaits copyright assignment for
1650 * Makefile.in (USER_CFLAGS): Add macro specifically reserved
1651 for getting custom flags into CFLAGS when doing makes.
1653 * configure.in: Add config information for stratus.
1655 Thu Jan 16 00:51:46 1992 Fred Fish (fnf at cygnus.com)
1657 * dbxread.c (process_one_symbol): Pass address of structure
1658 to complain(), rather than the whole structure.

1668 values that are computed off a base register.
1670 * dwarfread.c (new_symbol): Rework TAG_global_variable and
1671 TAG_local_variable cases to account for static variables
1672 within function scopes.
1674 Tue Jan 14 12:28:52 1992 Stu Grossman (grossman at cygnus.com)
1676 * inflow.c: remove #include <sys/dir.h>. Not necessary, and
1677 doesn't exist on some systems.
1679 * infrun.c (wait_for_inferior!!!!): Prevent gdb from hanging when
1680 nexting over recursive function calls.
1682 * target.c (target_read_string): Create this routine to read null
1683 terminated strings from the target. It deals with running off the
1684 end of memory elegantly as well. solib.c (find_solib): Use
1685 target_read_string() to avoid problems with running off the end of
1688 * inflow.c (child_terminal_info): #ifdef TIOCPGRP around lines
1689 that reference pgrp_inferior.
1691 Mon Jan 13 14:57:11 1992 Per Bothner (bothner at cygnus.com)
1693 * tm-mips.h: Removed BLOCK_ADDRESS_ABSOLUTE, now that
1694 mips-tfile has been hacked to act more "traditionally."
1695 * dbxread.c: Fixed typo in comment.
