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

435 * frame.h (FRAME_CHAIN_VALID): Provide default definition that
436 works for the majority of targets.
437 * tm-68k.h, tm-convex.h, tm-h8300.h, tm-i386v.h, tm-irix3.h,
438 tm-merlin.h, tm-mips.h, tm-pyr.h, tm-rs6000.h, tm-sparc.h,
439 tm-sun386.h, tm-tahoe.h, tm-umax.h, tm-vax.h (FRAME_CHAIN_VALID):
440 Use default definition in frame.h.
441 * frame.h (selected_frame_level): Make decl extern.
442 * objfiles.c, symfile.c (current_objfile): Moved to objfiles.c
443 * objfiles.c, symfile.c (symfile_objfile): Moved to objfiles.c
444 * partial-stab.h: Use new per-objfile entry info.
445 * symfile.h (struct objfile): Removed, moved to objfiles.h.
446 * symfile.h, objfiles.h (allocate_objfile, free_objfile,
447 free_all_objfiles, iterate_over_objfiles, iterate_over_symtabs,
448 iterate_over_psymtabs, have_partial_symbols, have_full_symbols,
449 have_minimal_symbols): Prototypes moved to objfiles.h.
450 * symfile.h, objfiles.h (ALL_OBJFILES, ALL_OBJFILES_SAFE):
451 Macros moved to objfiles.h.
452 * tm-h8300.h, tm-i386v4.h (FRAME_CHAIN_VALID_ALTERNATE): Define.
454 Thu Mar 19 18:49:45 1992 Per Bothner (bothner@cygnus.com)
456 More C++ improvements (pointers to members, qualified names).
457 * c-exp.y: Support exp.type::name and exp->type::name
458 syntaxes. (Unfortunately, doesn't work for static members.)
459 * c-exp.y, eval.c: Make type::~type work better.
460 * eval.c (evaluate_subexp: OP_SCOPE): Replace use of
461 value_static_field by value_struct_elt_for_reference.
462 * eval.c (evaluate_subexp): Merge code for STRUCTOP_MEMBER
463 and STRUCTOP_MPTR; cast arg1 to domain-type of arg2.
464 * eval.c (evaluate_subexp): Remove special case for UNOP_ADDR
465 for OP_SCOPE operand; no point in it now that we use lazy
466 reading of values, and use "reference to member" objects.
467 * gdbtypes.h: Clarify comment.
468 * valops.c: Change value_struct_elt_for_address to return
469 a reference (or variable), rather than a pointer. Change
470 the name to value_struct_elt_for_reference to reflect this.
471 Returning a reference instead of a address provides a
472 generalization, since we can use the routine for both
473 class::name as well as &class::name.
474 Also, recurse to handle multiple inheritance properly.
475 * valprint.c: Moved code to print pointer-to-members
476 to new function point_class_member. This allows a
477 "reference-to-member" to be printed using the same code.
478 * valprint.c (type_print_varspec_prefix): Avoid printing
479 "struct " for domains of class-member types.
480 * valops.c (search_struct_field): Inline code for simplified
481 version of value_static_field (which can then be deleted).
482 * value.h: Rename value_struct_elt_for_address to
483 value_struct_elt_for_reference. Delete value_static_field.
484 * values.c: Remove no longer used function value_static_field.

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

533 * symtab.c: Other fixes to improve handing of operators.
534 * valprint.c (type_print_base): Fix test for constructor.
535 * values.c (value_static_field): Allow evaluation of
536 CLASS::METHOD, returning a function pointer.
538 Wed Mar 18 08:39:52 1992 Fred Fish (fnf@cygnus.com)
540 * Makefile.in (VERSION): Roll 4.4.6.
541 * exec.c (exec_file_command): Add code to ignore optional args
542 passed in by file_command() for use in symbol_file_command().

550 * remote-vx.c (vx_load_command, add_symbol_stub):
551 Symbol_file_add() takes an additional arg.
552 * solib.c (symbol_add_stub): Symbol_file_add() takes an

561 readnow functionality moved to symbol_file_add().
562 * symfile.c (symfile_init): Eliminate local copy of bfd.

611 and using warning() instead of printfs.
612 * m2-exp.y: Define malloc to xmalloc and realloc to xrealloc.
613 * main.c (main): Add declaration for warning_pre_print and set it
614 similarly to error_pre_print. Add declarations for
615 mapped_symbol_files and readnow_symbol_files. Add appropriate
616 definitions to long_options[].
617 * minsyms.c: Trivial fix to comment.
618 * objfiles.c (allocate_objfile): Substantially rewritten for
619 using mapped symbol files.
620 * objfiles.c (throughout): Change from using per-objfile
621 xmalloc/xrealloc/free functions to xmmalloc/xmrealloc/mfree.

642 Sun compiler grumblings when PTR is char *.
643 * symtab.c (lookup_symbol): Cast return value of iterate_over_
644 msymbols() to correct pointer type.

666 * xcoffread.c: Only enable compilation of debugging functions
667 if IBM6000 is defined. Fails to compile otherwise.
669 Fri Mar 13 15:51:11 1992 K. Richard Pixley (rich@cygnus.com)
671 * Makefile.in: pass MAKEINFO down on info.

683 * minsyms.c, symfile.c: Changes that may be generally
684 applicable, but are #ifdef IBM6000 for now.
685 * rs6000-xdep.c: Fixed typo in comment.
686 * rs6000-tdep.c: Non-substatial changes.
687 * xoffread.c: The main change here is addition of some

696 Sun Mar 8 21:17:48 1992 Fred Fish (fnf@cygnus.com)
698 * symfile.h: Add prototype for iterate_over_msymbols().
699 * symtab.c (cplus_mangled_symbol): Add function.
700 * symtab.c (lookup_symbol): Call cplus_mangled_symbol via
701 iterate_over_msymbols to find demangled C++ symbol.
702 * xcoffexec.c (relocate_minimal_symbol): Return meaningful

758 * All GDB files that #include defs.h: Removed stdio.h.
759 (defs.h): #include stdio.h.
761 Mon Mar 2 23:00:12 1992 Steve Chamberlain (sac@thepub.cygnus.com)
763 * gdbtypes.c (lookup_pointer_type): initialize the TYPE_LENGTH of

770 Sun Mar 1 17:41:09 1992 Per Bothner (bothner@cygnus.com)
772 * rs6000-xdep.c (frame_initial_stack_address): Move
773 code to set frame->cache_fsr into new separate function

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

915 * mips-xdep.h: Avoid the embedded regs when on Unix.

933 symfile.c (syms_from_objfile): Re-do
934 insertion of longjmp breakpoints. Move all code into
935 breakpoint_re_set, and call that instead of
936 create_longjmp_breakpoint in symfile.c.
938 Thu Feb 27 06:11:05 1992 John Gilmore (gnu at cygnus.com)

1353 value.h: Prototypes for static functions; lint.
1354 * gdbtypes.h: Empty file to ease transition.
1356 Thu Feb 20 16:43:13 1992 Fred Fish (fnf at cygnus.com)

1368 target.c, target.h, valarith.c, valops.c, value.h, xcoffexec.c:
1369 Remove to_call_function and target_call_function, since it
1370 always calls the same thing (call_function_by_hand).
1371 * core.c, exec.c, solib.c: Rename target_ops sections =>
1373 * infcmd.c, inflow.c, infptrace.c, infrun.c, main.c, target.c,
1374 target.h: target_kill takes no args.
1375 * language.c (language_info): Scaffolding to allow briefer
1376 messages when the current language changes. FIXME.
1377 * xm-amix.h, xm-i386v4.h, xm-stratus.h: Define NORETURN to avoid
1378 complaints about volatile functions.
1379 * xm-sysv4.h (HAVE_MMAP): Define.
1381 Thu Feb 20 09:04:18 1992 Fred Fish (fnf at cygnus.com)

1394 Mon Feb 17 07:13:27 1992 Fred Fish (fnf at cygnus.com)
1396 * dwarfread.c (process_dies): Add case to handle TAG_pointer_type
1397 DIE's. Add new function read_tag_pointer_type() to read them.
1399 * dwarfread.c (dwarf_read_array_type, read_subroutine_type):
1400 When creating a new user defined type, check to see if a partial
1401 type already exists, and if so, bash it to fit.
1403 Fri Feb 14 19:00:17 1992 John Gilmore (gnu at cygnus.com)
1405 * coffread.c (decode_base_type): Pass long, not union.

1408 Thu Feb 13 17:14:28 1992 Fred Fish (fnf at cygnus.com)
1410 * elfread.c (elf_symtab_read): Fix code to correctly track
1411 changes in bfd for absolute symbols.

1421 Fri Feb 7 11:51:12 1992 Per Bothner (bothner at cygnus.com)
1423 * mips-tdep.c (mips_print_registers): Print correct register
1424 number for double pseudo-registers.
1426 Fri Feb 7 07:56:05 1992 John Gilmore (gnu at cygnus.com)
1428 * buildsym.c (read_struct_type): Avoid double-bump of parse ptr
1429 in the op$::OPERATOR. case. From Steven McCanne,
1430 <mccanne@horse.ee.lbl.gov>.
1432 * exec.c (set_section_name): Pass arg to exec_files_info;
1433 only call it if interactive. From Francis Kauth <fk@tv.tv.tek.com>.
1435 Thu Feb 6 17:41:32 1992 John Gilmore (gnu at cygnus.com)
1437 * main.c (print_gdb_version): Copyright msg: only this year.
1438 (cd_command): Avoid changing current_directory on error.
1440 Thu Feb 6 15:14:01 1992 Per Bothner (bothner at cygnus.com)
1442 * mipsread.c (parse_partial_symbols): Handle dependencies
1443 between partial symbol tables (when not doing stabs-in-ecoff).
1444 (This used to be handled by parse_fdr, but parse_fdr was
1445 incompatible with handling stabs-in-ecoff, so the code
1446 was re-written to not use parse_fdr. Unfortunately,
1447 the logic to handle dependencies was overlooked.)
1449 Thu Feb 6 11:51:39 1992 Steve Chamberlain (sac at rtl.cygnus.com)
1451 * coffread.c (read_enum_type): Use the size of a target int when
1453 * defs.h: added new #define for TARGET_PTR_BIT, defaults to size
1455 * h8300-tdep.c, remote-hms.c, tm-h8300.h: too many changes to count
1456 * symtab.c (lookup_reference_type, lookup_ptr_type): use
1457 TARGET_PTR_BIT to determine size of a pointer
1458 * values.c (unpack_long): when unpacking a REF or a PTR don't
1459 assume the size of the type.
1461 Wed Feb 5 22:29:59 1992 John Gilmore (gnu at cygnus.com)
1463 * mipsread.c (parse_symbol): Avoid clobbering enum pointer when
1464 looking at its members. Improve guess between struct and union,
1465 only assuming union if multiple members have offsets of zero.
1467 Tue Feb 4 18:05:44 1992 Per Bothner (bothner at cygnus.com)
1469 * mipsread.c: Use (FP0_REGNUM-32) instead of magic number 6.
1470 (This is just for clarity - and one day permitting us to
1471 change FP0_REGNUM from 38 to 32, which would make more sense.)
1472 * tm-mips.h: Added STAB_REG_TO_REGNUM macro, so that
1473 register numbers in stabs-in-ecoff get handled correctly.
1475 Sat Feb 1 04:45:10 1992 Stu Grossman (grossman at cygnus.com)
1477 * xm-vax.h, xm-vaxult.h, xm-vaxbsd.h, config/mh-vaxult,
1478 config/mh-vaxbsd, configure.in: Split up config stuff for Vaxen
1479 into BSD and Ultrix.
1481 Sat Feb 1 04:39:41 1992 John Gilmore (gnu at cygnus.com)
1483 * dbxread.c (dbx_symfile_init): Call malloc, not xmalloc.
1485 Sat Feb 1 04:15:41 1992 Stu Grossman (grossman at cygnus.com)
1487 * Makefile.in: Increment version to 4.4.1.
1488 * main.c (print_gdb_version): Update copyright notice.
1490 Sat Feb 1 01:43:11 1992 Per Bothner (bothner at cygnus.com)
1492 * mipsread.c: Prepend "struct " to the names of structure
1493 types, and similarly for enums and unions. (This used
1494 to be done, but got lost in the re-write to "guess" the
1495 difference between enum/struct/union.)
1496 Also, guess that a tag is an enum if the first member
1499 Fri Jan 31 21:45:51 1992 Stu Grossman (grossman at cygnus.com)
1501 * xm-vax.h: #ifndef ultrix around #include of endian.h and
1504 Fri Jan 31 00:05:01 1992 John Gilmore (gnu at cygnus.com)
1506 * Projects: Patching executables is done.
1507 * Makefile.in (VERSION): Roll to gdb-4.4.
1508 * README, WHATS.NEW: Update for gdb-4.4.
1510 * symfile.c (reread_symbols): Whenever we reread one object
1511 file's symbols, we must restart the scan, because the object_files
1512 chain has been permuted.
1514 * exec.c (exec_files_info): Split out into print_section_info.
1515 Print BFD filename of each section if it's not the default one.
1516 * core.c (core_files_info): Call print_section_info.
1518 * xm-vax.h: Include a few system header files whose definitions
1519 must precede defs.h.
1520 * language.c, language.h: Make some things const.
1521 * expression.h, main.c: const spreads like ooze.
1523 * mem-break.c (break_insn, break_insn_size): Use unsigned chars,
1524 since BREAKPOINT values can be >0x80.
1526 Thu Jan 30 17:21:14 1992 Stu Grossman (grossman at cygnus.com)
1528 * infrun.c, xm-i386sco.h: SCO needs to use setpgid().
1530 Thu Jan 30 01:04:23 1992 John Gilmore (gnu at cygnus.com)
1532 * sparc-pinsn.c: Remove kludge for preferring architectures.
1533 Remove #ifdef's for SORT_NEEDED. We need to sort the table, now
1534 and forever. Add `add' instruction to the set that get checked
1535 for a preceding `sethi' in order to print an absolute address.
1536 Corresponding changes in ../include/opcode/sparc.h needed
1537 to eliminate garbage instructions.
1539 Wed Jan 29 19:24:34 1992 Per Bothner (bothner at cygnus.com)
1541 * mipsread.c (parse_partial_symbols): Make sure partial
1542 symbols are created for external symbols (as used to be
1543 the case). This is a bit of a pain with the mips-coff.
1544 It uses a table which points to all of the external
1545 symbols belonging to a particular FDR or psymtab.
1546 Once we've generated this table, we might as well save
1547 it, and then use it in psymtab_to_symtab_1 to find
1548 the symbols to pass to parse_external().
1549 * symfile.c, symfile.c: New function start_psymtab_common
1550 to share the common parts of allocating a new psymtab
1551 for dbxread, mipsread (and later dwarfread). Its code
1552 was pulled out from start_psymtab in dbxread.c.
1553 * dbxread.c (start_psymtab): Use start_psymtab_common().
1555 * valprint.c (val_print): If there is an error when trying
1556 to print a string, check to see if there really is a problem
1557 by reading just one character. If that works, assume
1560 Wed Jan 29 18:58:43 1992 Stu Grossman (grossman at cygnus.com)
1562 * sparc-pinsn.c (compare_opcodes): Make it prefer v6, v7,
1563 cypress, v8 mnemonics in that order.
1565 Tue Jan 28 17:32:13 1992 Per Bothner (bothner at cygnus.com)
1567 * sparc-pinsn.c: Put the qsort() back in.
1569 Mon Jan 27 18:51:03 1992 John Gilmore (gnu at cygnus.com)
1571 * findvar.c (read_register, write_register): Handle machines
1572 where REGISTER_TYPE is not the same size as "int".
1574 Handle debug symbols in dynamically loaded (relocated) code:
1576 * dbxread.c (read_ofile_symtab): Fix up N_CATCH better. Pass
1577 offset to process_one_symbol.
1578 (process_one_symbol): Take new offset parameter. Add it into
1579 appropriate symbol types to relocate symbols to loaded addresses.
1580 Handle all possible symbol types, and complain() about types that
1581 we don't expect to see.
1582 * mipsread.c (psymtab_to_symtab_1): Pass offset of zero to
1583 process_one_symbol (FIXME, should pass real offset).
1587 * breakpoint.c (resolve_sal_pc): Split out code to resolve a
1589 (set_breakpoint, break_command_1, until_break_command,
1590 catch_command_1, breakpoint_re_set_one): Use it.
1591 * symtab.h (resolve_sal_pc): Declare.
1592 * infcmd.c (jump_command): Use resolve_sal_pc.
1594 * source.c (list_command): Shorten "FILE, line N" to "FILE:N".
1596 * putenv.c (putenv): Avoid unportably casting pointers to unsigneds.
1598 * c-exp.y (yylex): `this' and `template' are only tokens in C++.
1600 * xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
1601 xm-np1.h, xm-pn.h, xm-pyr.h, xm-rtbsd.h, xm-symmetry.h, xm-umax.h:
1602 Remove MISSING_VPRINTF declaration, and superfluous "kgdb" defines.
1604 Mon Jan 27 15:46:21 1992 Stu Grossman (grossman at cygnus.com)
1606 * dbxread.c (process_one_symbol): Make a first cut at handling
1607 symbol tables generated by Sun's acc. (#ifdef'd out, FIXME.)
1609 * symtab.c (find_pc_line): Fix stepping into and out of #included
1612 Mon Jan 27 13:00:55 1992 Stu Grossman (grossman at cygnus.com)
1614 * Makefile.in (OPCODES): Remove OPCODES defs and refs. There is
1615 no longer any need to copy ../include/opcode/* into gdb.
1617 Mon Jan 27 12:30:38 1992 John Gilmore (gnu at cygnus.com)
1619 * ChangeLog, ChangeLog-9091: Split ChangeLog at 1992.
1621 Sun Jan 26 19:05:40 1992 Per Bothner (bothner at cygnus.com)
1623 * valprint.c (type_print_base, type_print_method_args):
1624 Print C++ constructor methods without bogus "return type."
1626 Sat Jan 25 15:57:59 1992 Fred Fish (fnf at cygnus.com)
1628 * infptrace.c (child_xfer_memory): Parameter "target" should
1629 be a pointer to a structure, not the entire structure.
1631 Fri Jan 24 01:30:27 1992 Fred Fish (fnf at cygnus.com)
1633 * depend: Convert the couple of references to ansidecl.h that
1634 used the local gdb version to use the ../include version.
1636 Thu Jan 23 22:24:43 1992 Fred Fish (fnf at cygnus.com)
1639 (child_xfer_memory): Takes pointer to a struct, not entire struct.
1640 (inferior_proc_init): Fix non-ANSI version of args.
1641 (attach): Call print_sys_errmsg with correct number of args.
1642 (mappingflags): Make static, does not need to be global.
1644 * i386-tdep.c (i386_frame_num_args): Takes a pointer to a struct
1645 not the entire struct itself.
1647 * valops.c (value_assign): Cast some args to modify_field() and
1648 {read,write}_register_bytes() correctly.
1650 * ansidecl.h: Removed, is duplicate of ../include/ansidecl.h
1652 * Makefile.in (MALLOCSRC): Removed reference to removed local
1655 * dwarfread.c (list_in_scope): Needs an initial value, use file
1658 Mon Jan 20 19:06:28 1992 Stu Grossman (grossman at cygnus.com)
1660 * main.c (main): Make option_index local to keep new getopt happy.
1661 main.c, solib.c, Makefile.in: Update copyright notices.
1663 Mon Jan 20 08:54:00 1992 Michael Tiemann (tiemann at cygnus.com)
1665 * cplus-dem.c (cplus_demangle): Correctly demangle destructors.
1667 Sat Jan 18 17:17:45 1992 Stu Grossman (grossman at cygnus.com)
1669 * Makefile.in (HFILES): Add partial-stab.h.
1671 Sat Jan 18 16:45:01 1992 Fred Fish (fnf at cygnus.com)
1673 * config/mh-stratus, config/mt-stratus, tm-stratus.h, xm-stratus.h:
1674 New files for stratus. Not complete enough to actually build
1675 on the Stratus machine; that awaits copyright assignment for
1678 * Makefile.in (USER_CFLAGS): Add macro specifically reserved
1679 for getting custom flags into CFLAGS when doing makes.
1681 * configure.in: Add config information for stratus.
1683 Thu Jan 16 00:51:46 1992 Fred Fish (fnf at cygnus.com)

1696 values that are computed off a base register.
1698 * dwarfread.c (new_symbol): Rework TAG_global_variable and
1699 TAG_local_variable cases to account for static variables
1700 within function scopes.
1702 Tue Jan 14 12:28:52 1992 Stu Grossman (grossman at cygnus.com)
1704 * inflow.c: remove #include <sys/dir.h>. Not necessary, and
1705 doesn't exist on some systems.
1707 * infrun.c (wait_for_inferior!!!!): Prevent gdb from hanging when
1708 nexting over recursive function calls.
1710 * target.c (target_read_string): Create this routine to read null
1711 terminated strings from the target. It deals with running off the
1712 end of memory elegantly as well. solib.c (find_solib): Use
1713 target_read_string() to avoid problems with running off the end of
1716 * inflow.c (child_terminal_info): #ifdef TIOCPGRP around lines
1717 that reference pgrp_inferior.

1721 * tm-mips.h: Removed BLOCK_ADDRESS_ABSOLUTE, now that
1722 mips-tfile has been hacked to act more "traditionally."
1723 * dbxread.c: Fixed typo in comment.
1725 Sun Jan 12 13:08:36 1992 Per Bothner (bothner at cygnus.com)
1727 * mips-tdep.c (mips_skip_prologue): Add some number of
1728 'sw' instructions before 'addiu' adjusts the stack.

1732 * dwarfread.c (start_symtab, end_symtab, scopecount, openscope,
1733 freescope, buildblock closescope, record_line, add_symbol_to_list,
1734 gatherblocks, make_blockvector): Extensive changes to switch
1735 to generic symbol table building code in buildsym.c. Remove
1736 scope tree structures and functions, symbol table building
1737 functions, and lots of other small changes.
1739 * dwarfread.c: Add new macros GCC_PRODUCER and STREQN. Remove
1740 GCC_COMPILED_FLAG_SYMBOL and GCC2_COMPILED_FLAG_SYMBOL.
1742 Tue Jan 7 13:09:57 1992 Stu Grossman (grossman at cygnus.com)
1744 * buildsym.c (cleanup_undefined_types): Add support for enums.
1745 This fixes the 'GDB internal error. cleanup_undefined_types with

1754 * sparc-pinsn.c: Rename bitfields that overlap with macro names
1755 in ../include/opcode/sparc.h.
1757 Wed Jan 1 04:29:00 1992 Fred Fish (fnf at cygnus.com)
1759 * Makefile.in: Change tm-svr4.h to tm-sysv4.h. Change xm-svr4.h
1760 to xm-sysv4.h. Split OPCODE_DIR into OPCODE_DIR1 and OPCODE_DIR2
1761 to reflect actual locations of opcode files, so TAGS target will
1764 * i386-tdep.c: Change an erroneous 'm68k' reference to 'i386'.
1766 * i386-tdep.c (supply_fpregset, fill_fpregset): Remove m68k
1769 * m68k-tdep.c (supply_fpregset, fill_fpregset): Fix array
1770 dereferencing to access the correct elements.
1772 * valops.c (value_addr): Declare return type of external func
1775 * xcoffread.c: Undefine next_symbol_text before redefining it.
