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

446 inside_entry_func, inside_entry_file, inside_main_func,
448 * symfile.c (syms_from_objfile): Common entry point init code
449 moved to init_entry_point_info() and call init_entry_point_info().
450 * symfile.h (init_entry_point_info): Include prototype.
451 * xcoffread.c (aixcoff_symfile_init): Common entry point init code
452 moved to symfiles.c and call init_entry_point_info().

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

515 elfread.c (xxx_symfile_new_init, xxx_symfile_init, xxx_symfile_read):
516 Pass pointer to struct objfile rather than pointer to sym_fns.
517 Change references inside each function accordingly. Allocate any
518 symbol file specific info in the per-objfile memory region.
519 * dbxread.c (free_and_init_header_files): Break function into
520 free_header_files(), called from dbx_symfile_finish(), and
521 init_header_files(), called from dbx_new_init().
522 * dbxread.c (dbx_new_init): Move deallocation things to new
523 dbx_symfile_finish function.
524 * elfread.c (elf_new_init): Call buildsym_new_init().
525 * objfiles.c (free_objfile): Call the appropriate symfile_finish()
526 routine for the objfile before deallocating other stuff.
527 * sparc-tdep.c (get_longjmp_target): Cast target_read_memory arg.
528 * symfile.h: Move struct sym_fns to before struct objfile def.
529 Add sym_finish function pointer and change prototypes of other
530 function pointers to reflect passing struct objfile pointer rather
531 than struct sym_fns pointer.
532 * symfile.c: Remove now obsolete symtab_fns pointer.
533 * symfile.c (symfile_init): Renamed to find_sym_fns, and now only
534 locates the correct sym_fns struct for the given objfile.
535 * symfile.c (syms_from_objfile, symbol_file_add): Restructured
536 for better support of mapped symbol tables.
537 * symfile.c (symbol_file_command): Remove obsolete code using
539 * symfile.h: Remove duplicate declarations for symfile_objfile,
540 entry_point, and object_files.
541 * target.c (target_info): Compare symfile_objfile to NULL.
542 * xcoffread.c (aixcoff_new_init): Move deallocation stuff to
543 aixcoff_symfile_finish().
545 Wed Mar 18 18:22:46 1992 Fred Fish (fnf@cygnus.com)

556 * valprint.c (type_print_base): Fix test for constructor.
557 * values.c (value_static_field): Allow evaluation of
558 CLASS::METHOD, returning a function pointer.

562 * Makefile.in (VERSION): Roll 4.4.6.
563 * exec.c (exec_file_command): Add code to ignore optional args

798 message back on, after cleaning up BFD.
800 * breakpoint.c (breakpoint_re_set): Removed (at least for now)

805 but protected by #ifndef MALLOC_INCOMPATIBLE.
806 * objfiles.c: Undo previous change: Use malloc/realloc
807 for objfile malloc/realloc fields (but add a cast).
808 * xcoffexec.c: Suppress an error message (for now).
810 Sat Feb 29 14:43:02 1992 Per Bothner (bothner@cygnus.com)
812 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
813 [Mail dated Fri, 21 Feb 92 13:14:54 -0800]
814 * buildsym.c: Use smash_to_pointer_type() to handle forward type
816 * xcoffread.c: Modifications to C_DECL storage class handling, and
817 introduction of an old smash_to_pointer_type() routine.
819 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
820 [Mail dated Thu, 20 Feb 92 13:57:16 -0800]
821 * rs6000-xdep.c, rs6000-tdep.c, tm-rs6000.h: function_frame_info()
822 parameters have been modified.
824 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
825 [Mail dated Thu, 20 Feb 92 10:10:05 -0800]
826 * rs6000-tdep.c: Before Feb 5 92, register_valid[] array was not used,
827 and fetch_inferior_registers() always fetched all the registers
828 resulting valid register values at hand all the time. Pushing a dummy
829 frame did not require validating all register values first. After
830 putting the above mechanism into action, we didn't have valid registers
831 values always ready. Thus, all registers need to be fetched before
832 pushing a dummy frame now.
834 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
835 [Mail dated Thu, 13 Feb 92 16:22:44 -0800]
836 * rs6000-xdep.c: frame_initial_stack_address() function to calculate
837 the starting address (actual frame address) of a frame.
838 * rs6000-tdep.c: modifications to function_frame_info() to see if
839 function reserves a frame pointer register (alloca register)

841 FRAME_LOCALS_ADDRESS has been updated to support debugging of
842 functions with alloca() calls.
844 Sun Mar 1 13:13:39 1992 Fred Fish (fnf@cygnus.com)
846 * xm-sysv4.h: Provide definitions/prototypes for host environment
847 functions for which no definitions or prototypes are provided in
848 any currently included gdb or host environment header files.
849 For SVR4, this currently includes malloc and realloc, which cannot
850 be portably prototyped in any gdb include file.
852 Sat Feb 29 14:43:02 1992 Per Bothner (bothner@cygnus.com)
854 * buildsym.h: Remove obsolete variable file_stabs.
856 * Makefile.in: Move place where configure merges in host-
857 and target-dependent fragments later, so the latter
858 can override (say) GNU_MALLOC.
859 * config/mh-rs6000: Use system malloc. Otherwise, I
860 ended up with *two* incompatible versions of malloc
861 (functions in libc would call the malloc in libc).
862 I assume this is a shared library problem.
864 * remote.c: Fix (presumed) typo.
865 * objfiles.c: Use xmalloc/xrealloc instead of
866 malloc/realloc (since the latter are no longer declared).
868 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
869 [Mail dated Thu, 6 Feb 1992 10:22:02 -0800]
870 * rs6000-xdep.c: Improvements to fetch_inferior_registers() to
871 handle individual registers.
872 * tm-rs6000.h: Fix SAVED_PC_AFTER_CALL macro to handle pc value
873 correctly in case it wasn't cached yet. (A problem showed up
874 after fetching individual registers.)
875 * buildsym.c: Disable type_synonym_name's type name overwriting
876 in cases it is unnecesary. rs6000 portation doesn't use
877 type_synonym_name, and it used to nullify type names
878 * xcoffread.c: to handle g++'s typename abbreviation, fill in a
879 type's name as soon as space for that type is allocated.
880 * xcoffread.c: ignore a section's lineno information if it is
881 not `.text'. (In rs6000 bfd portation integration, skipping over
882 `.pad' sections are ignored since it was in machine independent
883 part of the code. Thus, a problem of fake sections with invalid
884 lineno information arised.)
886 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
887 [Mail dated Thu, 6 Feb 1992 13:26:22 -0800]
888 * rs6000-tdep.c: make function_frame_info() work whether or not
889 reading from a core file.
890 * tm-rs6000.h: Implementation of FRAME_FIND_SAVED_REGS macro.
892 * infrun.c. main.c, printcmd.c. symtab.c:
893 More changes from IBM for rs6000.
896 Thu Feb 27 22:57:19 1992 Per Bothner (bothner@cygnus.com)
898 * rs6k-opcode.h, tm-rs6000.h, xm-rs6000.h, rs6000-tdep.c,
899 rs6000-xdep.c, xcoffexec.c, xcoffread.c:
900 Merge in changes (mostly from IBM) for RS6000.
901 * breakpoint.c, buildsym.c, infptrace.c, stack.c, symtab.c:
902 More changes from IBM for RS6000. These are in machine-
903 independent code, and probably could do with some cleaning
904 up. The most questionable of these are #ifdef IBM6000.
905 * infrun.c, sparc-tdep.c: Pass a parameter (signal number)
906 to single_step() (for consistency with rs6000 and i860).
907 * utils.c: Allow the 1st arg to xrealloc to be NULL
908 (in which case do malloc). This removes the need for
909 some tests in xcoff code (and perhaps other places?).
910 * coffread.c: Removed variables last_source_file,
911 type_vector, and type_vector_length as these are now
912 defined by buildsym.[ch].
913 * defs.h: Remove prototypes for malloc and realloc, since
914 these should only be used to implement xmalloc and xrealloc,
915 and they conflict with <stdlib.h> in AIX - where they
916 return void* even when __STDC__ isn't defined. Sigh.
917 * munch: Recognize *initialize* in data as well as text
918 (AIX uses data). Also, incorporate a patch from Garrett
919 Wollman <wollman@uvm-gen.uvm.edu> to make the sed script
920 much more sensible, by only trying to match the name of
921 the initialize_foo function, and not the junk before it.
923 Thu Feb 27 20:07:43 1992 Stu Grossman (grossman at cygnus.com)
925 * breakpoint.c (breakpoint_re_set_one): Don't reset breakpoint
926 unless symbol table indicates that something has changed.
928 Thu Feb 27 11:48:47 1992 John Gilmore (gnu at cygnus.com)
930 * remote.c: Make it work for embedded MIPS. Increase buffer
931 size, and use throughout. Round buffer size up if too many regs.
932 Support baud rate setting and try for an 8-bit path. If
933 interrupted while waiting for target, send a ^C down the wire.
934 Avoid single-byte reads.
935 * tm-mips.h: Add more embedded-system registers to REGISTER_NAMES
937 * mips-xdep.h: Avoid the embedded regs when on Unix.
939 * mipsread.c: Byte-swap the symbol table structures, using
940 routines from ecoff.c, to read a symbol table written in any
941 of the four possible byte orders.
942 * configure.in (mips-big-* target): Same as Sony News.
943 * config/mt-bigmips, config/mt-littlemips: Add ecoff.o.

951 * (breakpoint_1): Reformat display of 'info break' to show new
953 * (create_longjmp_breakpoint, breakpoint_re_set,
954 breakpoint_re_set_one, enable/disable_longjmp_breakpoint),
955 symfile.c (syms_from_objfile): Re-do
956 insertion of longjmp breakpoints. Move all code into
957 breakpoint_re_set, and call that instead of
958 create_longjmp_breakpoint in symfile.c.
960 Thu Feb 27 06:11:05 1992 John Gilmore (gnu at cygnus.com)
962 * breakpoint.h (ALL_BREAKPOINTS_SAFE): Add.

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

994 objfile changes. Probably seriously broken still, but it
997 Sat Feb 22 00:56:39 1992 Stu Grossman (grossman at cygnus.com)

1019 xcoffread.c: Change all callers.

1390 target.c, target.h, valarith.c, valops.c, value.h, xcoffexec.c:
1391 Remove to_call_function and target_call_function, since it
1392 always calls the same thing (call_function_by_hand).
1393 * core.c, exec.c, solib.c: Rename target_ops sections =>
1395 * infcmd.c, inflow.c, infptrace.c, infrun.c, main.c, target.c,
1396 target.h: target_kill takes no args.
1397 * language.c (language_info): Scaffolding to allow briefer
1398 messages when the current language changes. FIXME.
1399 * xm-amix.h, xm-i386v4.h, xm-stratus.h: Define NORETURN to avoid
1400 complaints about volatile functions.
1401 * xm-sysv4.h (HAVE_MMAP): Define.
1403 Thu Feb 20 09:04:18 1992 Fred Fish (fnf at cygnus.com)

1412 * m2-exp.y: Remove unused CONST; Rename OR and AND.
1413 * utils.c: Avoid declaring malloc and realloc. Lint.

1416 Mon Feb 17 07:13:27 1992 Fred Fish (fnf at cygnus.com)
1418 * dwarfread.c (process_dies): Add case to handle TAG_pointer_type
1419 DIE's. Add new function read_tag_pointer_type() to read them.
1421 * dwarfread.c (dwarf_read_array_type, read_subroutine_type):
1422 When creating a new user defined type, check to see if a partial
1423 type already exists, and if so, bash it to fit.
1425 Fri Feb 14 19:00:17 1992 John Gilmore (gnu at cygnus.com)
1427 * coffread.c (decode_base_type): Pass long, not union.

1430 Thu Feb 13 17:14:28 1992 Fred Fish (fnf at cygnus.com)
1432 * elfread.c (elf_symtab_read): Fix code to correctly track
1433 changes in bfd for absolute symbols.
1435 Thu Feb 13 12:43:29 1992 Stu Grossman (grossman at cygnus.com)
1437 * xm-vaxbsd.h: Close off comment.
1439 Thu Feb 13 07:45:19 1992 Fred Fish (fnf at cygnus.com)

1446 number for double pseudo-registers.
1448 Fri Feb 7 07:56:05 1992 John Gilmore (gnu at cygnus.com)
1450 * buildsym.c (read_struct_type): Avoid double-bump of parse ptr
1451 in the op$::OPERATOR. case. From Steven McCanne,
1452 <mccanne@horse.ee.lbl.gov>.
1454 * exec.c (set_section_name): Pass arg to exec_files_info;
1455 only call it if interactive. From Francis Kauth <fk@tv.tv.tek.com>.
1457 Thu Feb 6 17:41:32 1992 John Gilmore (gnu at cygnus.com)
1459 * main.c (print_gdb_version): Copyright msg: only this year.
1460 (cd_command): Avoid changing current_directory on error.
1462 Thu Feb 6 15:14:01 1992 Per Bothner (bothner at cygnus.com)
1464 * mipsread.c (parse_partial_symbols): Handle dependencies
1465 between partial symbol tables (when not doing stabs-in-ecoff).
1466 (This used to be handled by parse_fdr, but parse_fdr was
1467 incompatible with handling stabs-in-ecoff, so the code
1468 was re-written to not use parse_fdr. Unfortunately,
1469 the logic to handle dependencies was overlooked.)
1471 Thu Feb 6 11:51:39 1992 Steve Chamberlain (sac at rtl.cygnus.com)
1473 * coffread.c (read_enum_type): Use the size of a target int when
1475 * defs.h: added new #define for TARGET_PTR_BIT, defaults to size
1477 * h8300-tdep.c, remote-hms.c, tm-h8300.h: too many changes to count
1478 * symtab.c (lookup_reference_type, lookup_ptr_type): use
1479 TARGET_PTR_BIT to determine size of a pointer
1480 * values.c (unpack_long): when unpacking a REF or a PTR don't
1481 assume the size of the type.
1483 Wed Feb 5 22:29:59 1992 John Gilmore (gnu at cygnus.com)
1485 * mipsread.c (parse_symbol): Avoid clobbering enum pointer when
1486 looking at its members. Improve guess between struct and union,
1487 only assuming union if multiple members have offsets of zero.
1489 Tue Feb 4 18:05:44 1992 Per Bothner (bothner at cygnus.com)
1491 * mipsread.c: Use (FP0_REGNUM-32) instead of magic number 6.
1492 (This is just for clarity - and one day permitting us to
1493 change FP0_REGNUM from 38 to 32, which would make more sense.)
1494 * tm-mips.h: Added STAB_REG_TO_REGNUM macro, so that
1495 register numbers in stabs-in-ecoff get handled correctly.
1497 Sat Feb 1 04:45:10 1992 Stu Grossman (grossman at cygnus.com)
1499 * xm-vax.h, xm-vaxult.h, xm-vaxbsd.h, config/mh-vaxult,
1500 config/mh-vaxbsd, configure.in: Split up config stuff for Vaxen
1501 into BSD and Ultrix.
1503 Sat Feb 1 04:39:41 1992 John Gilmore (gnu at cygnus.com)
1505 * dbxread.c (dbx_symfile_init): Call malloc, not xmalloc.
1507 Sat Feb 1 04:15:41 1992 Stu Grossman (grossman at cygnus.com)
1509 * Makefile.in: Increment version to 4.4.1.
1510 * main.c (print_gdb_version): Update copyright notice.
1512 Sat Feb 1 01:43:11 1992 Per Bothner (bothner at cygnus.com)
1514 * mipsread.c: Prepend "struct " to the names of structure
1515 types, and similarly for enums and unions. (This used
1516 to be done, but got lost in the re-write to "guess" the
1517 difference between enum/struct/union.)
1518 Also, guess that a tag is an enum if the first member
1521 Fri Jan 31 21:45:51 1992 Stu Grossman (grossman at cygnus.com)
1523 * xm-vax.h: #ifndef ultrix around #include of endian.h and
1526 Fri Jan 31 00:05:01 1992 John Gilmore (gnu at cygnus.com)
1528 * Projects: Patching executables is done.
1529 * Makefile.in (VERSION): Roll to gdb-4.4.
1530 * README, WHATS.NEW: Update for gdb-4.4.
1532 * symfile.c (reread_symbols): Whenever we reread one object
1533 file's symbols, we must restart the scan, because the object_files
1534 chain has been permuted.
1536 * exec.c (exec_files_info): Split out into print_section_info.
1537 Print BFD filename of each section if it's not the default one.
1538 * core.c (core_files_info): Call print_section_info.
1540 * xm-vax.h: Include a few system header files whose definitions
1541 must precede defs.h.
1542 * language.c, language.h: Make some things const.
1543 * expression.h, main.c: const spreads like ooze.
1545 * mem-break.c (break_insn, break_insn_size): Use unsigned chars,
1546 since BREAKPOINT values can be >0x80.
1548 Thu Jan 30 17:21:14 1992 Stu Grossman (grossman at cygnus.com)
1550 * infrun.c, xm-i386sco.h: SCO needs to use setpgid().
1552 Thu Jan 30 01:04:23 1992 John Gilmore (gnu at cygnus.com)
1554 * sparc-pinsn.c: Remove kludge for preferring architectures.
1555 Remove #ifdef's for SORT_NEEDED. We need to sort the table, now
1556 and forever. Add `add' instruction to the set that get checked
1557 for a preceding `sethi' in order to print an absolute address.
1558 Corresponding changes in ../include/opcode/sparc.h needed
1559 to eliminate garbage instructions.
1561 Wed Jan 29 19:24:34 1992 Per Bothner (bothner at cygnus.com)
1563 * mipsread.c (parse_partial_symbols): Make sure partial
1564 symbols are created for external symbols (as used to be
1565 the case). This is a bit of a pain with the mips-coff.
1566 It uses a table which points to all of the external
1567 symbols belonging to a particular FDR or psymtab.
1568 Once we've generated this table, we might as well save
1569 it, and then use it in psymtab_to_symtab_1 to find
1570 the symbols to pass to parse_external().
1571 * symfile.c, symfile.c: New function start_psymtab_common
1572 to share the common parts of allocating a new psymtab
1573 for dbxread, mipsread (and later dwarfread). Its code
1574 was pulled out from start_psymtab in dbxread.c.
1575 * dbxread.c (start_psymtab): Use start_psymtab_common().
1577 * valprint.c (val_print): If there is an error when trying
1578 to print a string, check to see if there really is a problem
1579 by reading just one character. If that works, assume
1582 Wed Jan 29 18:58:43 1992 Stu Grossman (grossman at cygnus.com)
1584 * sparc-pinsn.c (compare_opcodes): Make it prefer v6, v7,
1585 cypress, v8 mnemonics in that order.
1587 Tue Jan 28 17:32:13 1992 Per Bothner (bothner at cygnus.com)
1589 * sparc-pinsn.c: Put the qsort() back in.
1591 Mon Jan 27 18:51:03 1992 John Gilmore (gnu at cygnus.com)
1593 * findvar.c (read_register, write_register): Handle machines
1594 where REGISTER_TYPE is not the same size as "int".
1596 Handle debug symbols in dynamically loaded (relocated) code:
1598 * dbxread.c (read_ofile_symtab): Fix up N_CATCH better. Pass
1599 offset to process_one_symbol.
1600 (process_one_symbol): Take new offset parameter. Add it into
1601 appropriate symbol types to relocate symbols to loaded addresses.
1602 Handle all possible symbol types, and complain() about types that
1603 we don't expect to see.
1604 * mipsread.c (psymtab_to_symtab_1): Pass offset of zero to
1605 process_one_symbol (FIXME, should pass real offset).
1609 * breakpoint.c (resolve_sal_pc): Split out code to resolve a
1611 (set_breakpoint, break_command_1, until_break_command,
1612 catch_command_1, breakpoint_re_set_one): Use it.
1613 * symtab.h (resolve_sal_pc): Declare.
1614 * infcmd.c (jump_command): Use resolve_sal_pc.
1616 * source.c (list_command): Shorten "FILE, line N" to "FILE:N".
1618 * putenv.c (putenv): Avoid unportably casting pointers to unsigneds.
1620 * c-exp.y (yylex): `this' and `template' are only tokens in C++.
1622 * xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
1623 xm-np1.h, xm-pn.h, xm-pyr.h, xm-rtbsd.h, xm-symmetry.h, xm-umax.h:
1624 Remove MISSING_VPRINTF declaration, and superfluous "kgdb" defines.
1626 Mon Jan 27 15:46:21 1992 Stu Grossman (grossman at cygnus.com)
1628 * dbxread.c (process_one_symbol): Make a first cut at handling
1629 symbol tables generated by Sun's acc. (#ifdef'd out, FIXME.)
1631 * symtab.c (find_pc_line): Fix stepping into and out of #included
1634 Mon Jan 27 13:00:55 1992 Stu Grossman (grossman at cygnus.com)
1636 * Makefile.in (OPCODES): Remove OPCODES defs and refs. There is
1637 no longer any need to copy ../include/opcode/* into gdb.
1639 Mon Jan 27 12:30:38 1992 John Gilmore (gnu at cygnus.com)
1641 * ChangeLog, ChangeLog-9091: Split ChangeLog at 1992.
1643 Sun Jan 26 19:05:40 1992 Per Bothner (bothner at cygnus.com)
1645 * valprint.c (type_print_base, type_print_method_args):
1646 Print C++ constructor methods without bogus "return type."
1648 Sat Jan 25 15:57:59 1992 Fred Fish (fnf at cygnus.com)
1650 * infptrace.c (child_xfer_memory): Parameter "target" should
1651 be a pointer to a structure, not the entire structure.
1653 Fri Jan 24 01:30:27 1992 Fred Fish (fnf at cygnus.com)
1655 * depend: Convert the couple of references to ansidecl.h that
1656 used the local gdb version to use the ../include version.
1658 Thu Jan 23 22:24:43 1992 Fred Fish (fnf at cygnus.com)
1661 (child_xfer_memory): Takes pointer to a struct, not entire struct.
1662 (inferior_proc_init): Fix non-ANSI version of args.
1663 (attach): Call print_sys_errmsg with correct number of args.
1664 (mappingflags): Make static, does not need to be global.
1666 * i386-tdep.c (i386_frame_num_args): Takes a pointer to a struct
1667 not the entire struct itself.
1669 * valops.c (value_assign): Cast some args to modify_field() and
1670 {read,write}_register_bytes() correctly.
1672 * ansidecl.h: Removed, is duplicate of ../include/ansidecl.h
1674 * Makefile.in (MALLOCSRC): Removed reference to removed local
1677 * dwarfread.c (list_in_scope): Needs an initial value, use file
1680 Mon Jan 20 19:06:28 1992 Stu Grossman (grossman at cygnus.com)
1682 * main.c (main): Make option_index local to keep new getopt happy.
1683 main.c, solib.c, Makefile.in: Update copyright notices.
1685 Mon Jan 20 08:54:00 1992 Michael Tiemann (tiemann at cygnus.com)
1687 * cplus-dem.c (cplus_demangle): Correctly demangle destructors.
1689 Sat Jan 18 17:17:45 1992 Stu Grossman (grossman at cygnus.com)

1693 Sat Jan 18 16:45:01 1992 Fred Fish (fnf at cygnus.com)
1695 * config/mh-stratus, config/mt-stratus, tm-stratus.h, xm-stratus.h:
1696 New files for stratus. Not complete enough to actually build
1697 on the Stratus machine; that awaits copyright assignment for
1700 * Makefile.in (USER_CFLAGS): Add macro specifically reserved
1701 for getting custom flags into CFLAGS when doing makes.
1703 * configure.in: Add config information for stratus.
1705 Thu Jan 16 00:51:46 1992 Fred Fish (fnf at cygnus.com)
1707 * dbxread.c (process_one_symbol): Pass address of structure
1708 to complain(), rather than the whole structure.

1712 * solib.c (solib_add_common_symbols): Only compile in when not
1713 using SVR4 style shared libraries.

1717 * dwarfread.c (locval): Add offreg flag to indicate location
1718 values that are computed off a base register.
1720 * dwarfread.c (new_symbol): Rework TAG_global_variable and
1721 TAG_local_variable cases to account for static variables
1722 within function scopes.
1724 Tue Jan 14 12:28:52 1992 Stu Grossman (grossman at cygnus.com)
1726 * inflow.c: remove #include <sys/dir.h>. Not necessary, and
1727 doesn't exist on some systems.
1729 * infrun.c (wait_for_inferior!!!!): Prevent gdb from hanging when
1730 nexting over recursive function calls.
1732 * target.c (target_read_string): Create this routine to read null
1733 terminated strings from the target. It deals with running off the
1734 end of memory elegantly as well. solib.c (find_solib): Use
1735 target_read_string() to avoid problems with running off the end of
1738 * inflow.c (child_terminal_info): #ifdef TIOCPGRP around lines
1739 that reference pgrp_inferior.
1741 Mon Jan 13 14:57:11 1992 Per Bothner (bothner at cygnus.com)
1743 * tm-mips.h: Removed BLOCK_ADDRESS_ABSOLUTE, now that
1744 mips-tfile has been hacked to act more "traditionally."
1745 * dbxread.c: Fixed typo in comment.
1747 Sun Jan 12 13:08:36 1992 Per Bothner (bothner at cygnus.com)
1749 * mips-tdep.c (mips_skip_prologue): Add some number of

1754 * dwarfread.c (start_symtab, end_symtab, scopecount, openscope,
1755 freescope, buildblock closescope, record_line, add_symbol_to_list,
1756 gatherblocks, make_blockvector): Extensive changes to switch
1757 to generic symbol table building code in buildsym.c. Remove
1758 scope tree structures and functions, symbol table building
1759 functions, and lots of other small changes.
1761 * dwarfread.c: Add new macros GCC_PRODUCER and STREQN. Remove
1762 GCC_COMPILED_FLAG_SYMBOL and GCC2_COMPILED_FLAG_SYMBOL.
1764 Tue Jan 7 13:09:57 1992 Stu Grossman (grossman at cygnus.com)
1766 * buildsym.c (cleanup_undefined_types): Add support for enums.

1781 * Makefile.in: Change tm-svr4.h to tm-sysv4.h. Change xm-svr4.h
1782 to xm-sysv4.h. Split OPCODE_DIR into OPCODE_DIR1 and OPCODE_DIR2
1783 to reflect actual locations of opcode files, so TAGS target will
1786 * i386-tdep.c: Change an erroneous 'm68k' reference to 'i386'.
1788 * i386-tdep.c (supply_fpregset, fill_fpregset): Remove m68k
1791 * m68k-tdep.c (supply_fpregset, fill_fpregset): Fix array
1792 dereferencing to access the correct elements.
1794 * valops.c (value_addr): Declare return type of external func
1797 * xcoffread.c: Undefine next_symbol_text before redefining it.
