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

509 Thu Mar 19 18:49:45 1992 Per Bothner (bothner@cygnus.com)
511 More C++ improvements (pointers to members, qualified names).
512 * c-exp.y: Support exp.type::name and exp->type::name
513 syntaxes. (Unfortunately, doesn't work for static members.)
514 * c-exp.y, eval.c: Make type::~type work better.
515 * eval.c (evaluate_subexp: OP_SCOPE): Replace use of
516 value_static_field by value_struct_elt_for_reference.
517 * eval.c (evaluate_subexp): Merge code for STRUCTOP_MEMBER
518 and STRUCTOP_MPTR; cast arg1 to domain-type of arg2.
519 * eval.c (evaluate_subexp): Remove special case for UNOP_ADDR
520 for OP_SCOPE operand; no point in it now that we use lazy
521 reading of values, and use "reference to member" objects.
522 * gdbtypes.h: Clarify comment.
523 * valops.c: Change value_struct_elt_for_address to return
524 a reference (or variable), rather than a pointer. Change
525 the name to value_struct_elt_for_reference to reflect this.
526 Returning a reference instead of a address provides a
527 generalization, since we can use the routine for both
528 class::name as well as &class::name.
529 Also, recurse to handle multiple inheritance properly.
530 * valprint.c: Moved code to print pointer-to-members
531 to new function point_class_member. This allows a
532 "reference-to-member" to be printed using the same code.
533 * valprint.c (type_print_varspec_prefix): Avoid printing
534 "struct " for domains of class-member types.
535 * valops.c (search_struct_field): Inline code for simplified
536 version of value_static_field (which can then be deleted).
537 * value.h: Rename value_struct_elt_for_address to
538 value_struct_elt_for_reference. Delete value_static_field.
539 * values.c: Remove no longer used function value_static_field.

548 elfread.c (xxx_symfile_new_init, xxx_symfile_init, xxx_symfile_read):
549 Pass pointer to struct objfile rather than pointer to sym_fns.
550 Change references inside each function accordingly. Allocate any
551 symbol file specific info in the per-objfile memory region.
552 * dbxread.c (free_and_init_header_files): Break function into
553 free_header_files(), called from dbx_symfile_finish(), and
554 init_header_files(), called from dbx_new_init().
555 * dbxread.c (dbx_new_init): Move deallocation things to new
556 dbx_symfile_finish function.
557 * elfread.c (elf_new_init): Call buildsym_new_init().
558 * objfiles.c (free_objfile): Call the appropriate symfile_finish()
559 routine for the objfile before deallocating other stuff.
560 * sparc-tdep.c (get_longjmp_target): Cast target_read_memory arg.
561 * symfile.h: Move struct sym_fns to before struct objfile def.
562 Add sym_finish function pointer and change prototypes of other
563 function pointers to reflect passing struct objfile pointer rather
564 than struct sym_fns pointer.
565 * symfile.c: Remove now obsolete symtab_fns pointer.
566 * symfile.c (symfile_init): Renamed to find_sym_fns, and now only
567 locates the correct sym_fns struct for the given objfile.
568 * symfile.c (syms_from_objfile, symbol_file_add): Restructured
569 for better support of mapped symbol tables.
570 * symfile.c (symbol_file_command): Remove obsolete code using
572 * symfile.h: Remove duplicate declarations for symfile_objfile,
573 entry_point, and object_files.
574 * target.c (target_info): Compare symfile_objfile to NULL.
575 * xcoffread.c (aixcoff_new_init): Move deallocation stuff to
576 aixcoff_symfile_finish().

859 * rs6000-tdep.c: Before Feb 5 92, register_valid[] array was not used,
860 and fetch_inferior_registers() always fetched all the registers
861 resulting valid register values at hand all the time. Pushing a dummy
862 frame did not require validating all register values first. After
863 putting the above mechanism into action, we didn't have valid registers
864 values always ready. Thus, all registers need to be fetched before
865 pushing a dummy frame now.

868 [Mail dated Thu, 13 Feb 92 16:22:44 -0800]
869 * rs6000-xdep.c: frame_initial_stack_address() function to calculate
870 the starting address (actual frame address) of a frame.
871 * rs6000-tdep.c: modifications to function_frame_info() to see if
872 function reserves a frame pointer register (alloca register)
873 * tm-rs6000.h: EXTRA_FRAME_INFO, FRAME_ARGS_ADDRESS and
874 FRAME_LOCALS_ADDRESS has been updated to support debugging of
875 functions with alloca() calls.
877 Sun Mar 1 13:13:39 1992 Fred Fish (fnf@cygnus.com)
879 * xm-sysv4.h: Provide definitions/prototypes for host environment
880 functions for which no definitions or prototypes are provided in
881 any currently included gdb or host environment header files.
882 For SVR4, this currently includes malloc and realloc, which cannot
883 be portably prototyped in any gdb include file.
885 Sat Feb 29 14:43:02 1992 Per Bothner (bothner@cygnus.com)
887 * buildsym.h: Remove obsolete variable file_stabs.
889 * Makefile.in: Move place where configure merges in host-
890 and target-dependent fragments later, so the latter
891 can override (say) GNU_MALLOC.
892 * config/mh-rs6000: Use system malloc. Otherwise, I
893 ended up with *two* incompatible versions of malloc
894 (functions in libc would call the malloc in libc).
895 I assume this is a shared library problem.
897 * remote.c: Fix (presumed) typo.
898 * objfiles.c: Use xmalloc/xrealloc instead of
899 malloc/realloc (since the latter are no longer declared).
901 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
902 [Mail dated Thu, 6 Feb 1992 10:22:02 -0800]
903 * rs6000-xdep.c: Improvements to fetch_inferior_registers() to
904 handle individual registers.
905 * tm-rs6000.h: Fix SAVED_PC_AFTER_CALL macro to handle pc value
906 correctly in case it wasn't cached yet. (A problem showed up
907 after fetching individual registers.)
908 * buildsym.c: Disable type_synonym_name's type name overwriting
909 in cases it is unnecesary. rs6000 portation doesn't use
910 type_synonym_name, and it used to nullify type names
911 * xcoffread.c: to handle g++'s typename abbreviation, fill in a
912 type's name as soon as space for that type is allocated.
913 * xcoffread.c: ignore a section's lineno information if it is
914 not `.text'. (In rs6000 bfd portation integration, skipping over
915 `.pad' sections are ignored since it was in machine independent
916 part of the code. Thus, a problem of fake sections with invalid
917 lineno information arised.)
919 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
920 [Mail dated Thu, 6 Feb 1992 13:26:22 -0800]
921 * rs6000-tdep.c: make function_frame_info() work whether or not
922 reading from a core file.
923 * tm-rs6000.h: Implementation of FRAME_FIND_SAVED_REGS macro.
925 * infrun.c. main.c, printcmd.c. symtab.c:
926 More changes from IBM for rs6000.
929 Thu Feb 27 22:57:19 1992 Per Bothner (bothner@cygnus.com)
931 * rs6k-opcode.h, tm-rs6000.h, xm-rs6000.h, rs6000-tdep.c,
932 rs6000-xdep.c, xcoffexec.c, xcoffread.c:
933 Merge in changes (mostly from IBM) for RS6000.
934 * breakpoint.c, buildsym.c, infptrace.c, stack.c, symtab.c:
935 More changes from IBM for RS6000. These are in machine-
936 independent code, and probably could do with some cleaning
937 up. The most questionable of these are #ifdef IBM6000.
938 * infrun.c, sparc-tdep.c: Pass a parameter (signal number)
939 to single_step() (for consistency with rs6000 and i860).
940 * utils.c: Allow the 1st arg to xrealloc to be NULL
941 (in which case do malloc). This removes the need for
942 some tests in xcoff code (and perhaps other places?).
943 * coffread.c: Removed variables last_source_file,
944 type_vector, and type_vector_length as these are now
945 defined by buildsym.[ch].
946 * defs.h: Remove prototypes for malloc and realloc, since
947 these should only be used to implement xmalloc and xrealloc,
948 and they conflict with <stdlib.h> in AIX - where they
949 return void* even when __STDC__ isn't defined. Sigh.
950 * munch: Recognize *initialize* in data as well as text
951 (AIX uses data). Also, incorporate a patch from Garrett
952 Wollman <wollman@uvm-gen.uvm.edu> to make the sed script
953 much more sensible, by only trying to match the name of
954 the initialize_foo function, and not the junk before it.
956 Thu Feb 27 20:07:43 1992 Stu Grossman (grossman at cygnus.com)
958 * breakpoint.c (breakpoint_re_set_one): Don't reset breakpoint
959 unless symbol table indicates that something has changed.
961 Thu Feb 27 11:48:47 1992 John Gilmore (gnu at cygnus.com)
963 * remote.c: Make it work for embedded MIPS. Increase buffer
964 size, and use throughout. Round buffer size up if too many regs.
965 Support baud rate setting and try for an 8-bit path. If
966 interrupted while waiting for target, send a ^C down the wire.
967 Avoid single-byte reads.
968 * tm-mips.h: Add more embedded-system registers to REGISTER_NAMES
970 * mips-xdep.h: Avoid the embedded regs when on Unix.
972 * mipsread.c: Byte-swap the symbol table structures, using
973 routines from ecoff.c, to read a symbol table written in any
974 of the four possible byte orders.
975 * configure.in (mips-big-* target): Same as Sony News.
976 * config/mt-bigmips, config/mt-littlemips: Add ecoff.o.
977 * ecoff.c: New file for symbol swapping routines.

983 * (get_number): Allow users to enter negative breakpoint numbers.
984 * (breakpoint_1): Reformat display of 'info break' to show new
986 * (create_longjmp_breakpoint, breakpoint_re_set,
987 breakpoint_re_set_one, enable/disable_longjmp_breakpoint),
988 symfile.c (syms_from_objfile): Re-do
989 insertion of longjmp breakpoints. Move all code into
990 breakpoint_re_set, and call that instead of
991 create_longjmp_breakpoint in symfile.c.
993 Thu Feb 27 06:11:05 1992 John Gilmore (gnu at cygnus.com)
995 * breakpoint.h (ALL_BREAKPOINTS_SAFE): Add.

1002 specifying a new symbol file.
1003 (reread_symbols): Stat the file name, don't fstat the descriptor.
1005 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)

1008 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
1009 copyrights to '92, changed some from Cygnus to FSF.

1019 * Makefile.in (VERSION): Roll to gdb-4.4.4.
1021 * symfile.c (symbol_file_command): strcmp => !strcmp.
1022 * breakpoint.h: Move prototypes to follow enum definition they need.
1023 * breakpoint.c, infrun.c: Lint.
1024 * printcmd.c: Use `enum enable' rather than `enum
1026 * mipsread.c: First pass at making it compile with the new
1027 objfile changes. Probably seriously broken still, but it
1030 Sat Feb 22 00:56:39 1992 Stu Grossman (grossman at cygnus.com)

1048 * minsyms.c (install_minimal_symbols): Add bunches to any
1049 existing minsyms in the objfile. Avoid extra mallocation
1050 by working directly in the obstack. Remove ignored `mainline' parm.

1052 xcoffread.c: Change all callers.
1053 * FIXME: We should be able to eliminate MAINLINE from all the
1054 symbol readers now, with a small bit of work.
1056 * valops.c, value.h: Lint.
1057 * remote-vx.c: Add missing break; statement. Bugfix by

1423 target.c, target.h, valarith.c, valops.c, value.h, xcoffexec.c:
1424 Remove to_call_function and target_call_function, since it
1425 always calls the same thing (call_function_by_hand).
1426 * core.c, exec.c, solib.c: Rename target_ops sections =>
1428 * infcmd.c, inflow.c, infptrace.c, infrun.c, main.c, target.c,
1429 target.h: target_kill takes no args.
1430 * language.c (language_info): Scaffolding to allow briefer
1431 messages when the current language changes. FIXME.
1432 * xm-amix.h, xm-i386v4.h, xm-stratus.h: Define NORETURN to avoid
1433 complaints about volatile functions.
1434 * xm-sysv4.h (HAVE_MMAP): Define.
1436 Thu Feb 20 09:04:18 1992 Fred Fish (fnf at cygnus.com)

1445 * m2-exp.y: Remove unused CONST; Rename OR and AND.
1446 * utils.c: Avoid declaring malloc and realloc. Lint.

1449 Mon Feb 17 07:13:27 1992 Fred Fish (fnf at cygnus.com)
1451 * dwarfread.c (process_dies): Add case to handle TAG_pointer_type
1452 DIE's. Add new function read_tag_pointer_type() to read them.
1454 * dwarfread.c (dwarf_read_array_type, read_subroutine_type):
1455 When creating a new user defined type, check to see if a partial
1456 type already exists, and if so, bash it to fit.
1458 Fri Feb 14 19:00:17 1992 John Gilmore (gnu at cygnus.com)
1460 * coffread.c (decode_base_type): Pass long, not union.

1479 number for double pseudo-registers.
1481 Fri Feb 7 07:56:05 1992 John Gilmore (gnu at cygnus.com)
1483 * buildsym.c (read_struct_type): Avoid double-bump of parse ptr

1485 <mccanne@horse.ee.lbl.gov>.
1487 * exec.c (set_section_name): Pass arg to exec_files_info;
1488 only call it if interactive. From Francis Kauth <fk@tv.tv.tek.com>.
1490 Thu Feb 6 17:41:32 1992 John Gilmore (gnu at cygnus.com)
1492 * main.c (print_gdb_version): Copyright msg: only this year.
1493 (cd_command): Avoid changing current_directory on error.
1495 Thu Feb 6 15:14:01 1992 Per Bothner (bothner at cygnus.com)
1497 * mipsread.c (parse_partial_symbols): Handle dependencies
1498 between partial symbol tables (when not doing stabs-in-ecoff).
1499 (This used to be handled by parse_fdr, but parse_fdr was
1500 incompatible with handling stabs-in-ecoff, so the code
1501 was re-written to not use parse_fdr. Unfortunately,
1502 the logic to handle dependencies was overlooked.)
1504 Thu Feb 6 11:51:39 1992 Steve Chamberlain (sac at rtl.cygnus.com)
1506 * coffread.c (read_enum_type): Use the size of a target int when
1508 * defs.h: added new #define for TARGET_PTR_BIT, defaults to size
1510 * h8300-tdep.c, remote-hms.c, tm-h8300.h: too many changes to count
1511 * symtab.c (lookup_reference_type, lookup_ptr_type): use
1512 TARGET_PTR_BIT to determine size of a pointer
1513 * values.c (unpack_long): when unpacking a REF or a PTR don't
1514 assume the size of the type.
1516 Wed Feb 5 22:29:59 1992 John Gilmore (gnu at cygnus.com)
1518 * mipsread.c (parse_symbol): Avoid clobbering enum pointer when
1519 looking at its members. Improve guess between struct and union,
1520 only assuming union if multiple members have offsets of zero.
1522 Tue Feb 4 18:05:44 1992 Per Bothner (bothner at cygnus.com)
1524 * mipsread.c: Use (FP0_REGNUM-32) instead of magic number 6.
1525 (This is just for clarity - and one day permitting us to
1526 change FP0_REGNUM from 38 to 32, which would make more sense.)
1527 * tm-mips.h: Added STAB_REG_TO_REGNUM macro, so that
1528 register numbers in stabs-in-ecoff get handled correctly.
1530 Sat Feb 1 04:45:10 1992 Stu Grossman (grossman at cygnus.com)
1532 * xm-vax.h, xm-vaxult.h, xm-vaxbsd.h, config/mh-vaxult,
1533 config/mh-vaxbsd, configure.in: Split up config stuff for Vaxen
1534 into BSD and Ultrix.
1536 Sat Feb 1 04:39:41 1992 John Gilmore (gnu at cygnus.com)
1538 * dbxread.c (dbx_symfile_init): Call malloc, not xmalloc.
1540 Sat Feb 1 04:15:41 1992 Stu Grossman (grossman at cygnus.com)
1542 * Makefile.in: Increment version to 4.4.1.
1543 * main.c (print_gdb_version): Update copyright notice.
1545 Sat Feb 1 01:43:11 1992 Per Bothner (bothner at cygnus.com)
1547 * mipsread.c: Prepend "struct " to the names of structure
1548 types, and similarly for enums and unions. (This used
1549 to be done, but got lost in the re-write to "guess" the
1550 difference between enum/struct/union.)
1551 Also, guess that a tag is an enum if the first member
1554 Fri Jan 31 21:45:51 1992 Stu Grossman (grossman at cygnus.com)
1556 * xm-vax.h: #ifndef ultrix around #include of endian.h and
1559 Fri Jan 31 00:05:01 1992 John Gilmore (gnu at cygnus.com)
1561 * Projects: Patching executables is done.
1562 * Makefile.in (VERSION): Roll to gdb-4.4.
1563 * README, WHATS.NEW: Update for gdb-4.4.
1565 * symfile.c (reread_symbols): Whenever we reread one object
1566 file's symbols, we must restart the scan, because the object_files
1567 chain has been permuted.
1569 * exec.c (exec_files_info): Split out into print_section_info.
1570 Print BFD filename of each section if it's not the default one.
1571 * core.c (core_files_info): Call print_section_info.
1573 * xm-vax.h: Include a few system header files whose definitions
1574 must precede defs.h.
1575 * language.c, language.h: Make some things const.
1576 * expression.h, main.c: const spreads like ooze.
1578 * mem-break.c (break_insn, break_insn_size): Use unsigned chars,
1579 since BREAKPOINT values can be >0x80.
1581 Thu Jan 30 17:21:14 1992 Stu Grossman (grossman at cygnus.com)
1583 * infrun.c, xm-i386sco.h: SCO needs to use setpgid().
1585 Thu Jan 30 01:04:23 1992 John Gilmore (gnu at cygnus.com)
1587 * sparc-pinsn.c: Remove kludge for preferring architectures.
1588 Remove #ifdef's for SORT_NEEDED. We need to sort the table, now
1589 and forever. Add `add' instruction to the set that get checked
1590 for a preceding `sethi' in order to print an absolute address.
1591 Corresponding changes in ../include/opcode/sparc.h needed
1592 to eliminate garbage instructions.
1594 Wed Jan 29 19:24:34 1992 Per Bothner (bothner at cygnus.com)
1596 * mipsread.c (parse_partial_symbols): Make sure partial
1597 symbols are created for external symbols (as used to be
1598 the case). This is a bit of a pain with the mips-coff.
1599 It uses a table which points to all of the external
1600 symbols belonging to a particular FDR or psymtab.
1601 Once we've generated this table, we might as well save
1602 it, and then use it in psymtab_to_symtab_1 to find
1603 the symbols to pass to parse_external().
1604 * symfile.c, symfile.c: New function start_psymtab_common
1605 to share the common parts of allocating a new psymtab
1606 for dbxread, mipsread (and later dwarfread). Its code
1607 was pulled out from start_psymtab in dbxread.c.
1608 * dbxread.c (start_psymtab): Use start_psymtab_common().
1610 * valprint.c (val_print): If there is an error when trying
1611 to print a string, check to see if there really is a problem
1612 by reading just one character. If that works, assume
1615 Wed Jan 29 18:58:43 1992 Stu Grossman (grossman at cygnus.com)
1617 * sparc-pinsn.c (compare_opcodes): Make it prefer v6, v7,
1618 cypress, v8 mnemonics in that order.
1620 Tue Jan 28 17:32:13 1992 Per Bothner (bothner at cygnus.com)
1622 * sparc-pinsn.c: Put the qsort() back in.
1624 Mon Jan 27 18:51:03 1992 John Gilmore (gnu at cygnus.com)
1626 * findvar.c (read_register, write_register): Handle machines
1627 where REGISTER_TYPE is not the same size as "int".
1629 Handle debug symbols in dynamically loaded (relocated) code:
1631 * dbxread.c (read_ofile_symtab): Fix up N_CATCH better. Pass
1632 offset to process_one_symbol.
1633 (process_one_symbol): Take new offset parameter. Add it into
1634 appropriate symbol types to relocate symbols to loaded addresses.
1635 Handle all possible symbol types, and complain() about types that
1636 we don't expect to see.
1637 * mipsread.c (psymtab_to_symtab_1): Pass offset of zero to
1638 process_one_symbol (FIXME, should pass real offset).
1642 * breakpoint.c (resolve_sal_pc): Split out code to resolve a
1644 (set_breakpoint, break_command_1, until_break_command,
1645 catch_command_1, breakpoint_re_set_one): Use it.
1646 * symtab.h (resolve_sal_pc): Declare.
1647 * infcmd.c (jump_command): Use resolve_sal_pc.
1649 * source.c (list_command): Shorten "FILE, line N" to "FILE:N".
1651 * putenv.c (putenv): Avoid unportably casting pointers to unsigneds.
1653 * c-exp.y (yylex): `this' and `template' are only tokens in C++.
1655 * xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
1656 xm-np1.h, xm-pn.h, xm-pyr.h, xm-rtbsd.h, xm-symmetry.h, xm-umax.h:
1657 Remove MISSING_VPRINTF declaration, and superfluous "kgdb" defines.
1659 Mon Jan 27 15:46:21 1992 Stu Grossman (grossman at cygnus.com)
1661 * dbxread.c (process_one_symbol): Make a first cut at handling
1662 symbol tables generated by Sun's acc. (#ifdef'd out, FIXME.)
1664 * symtab.c (find_pc_line): Fix stepping into and out of #included
1667 Mon Jan 27 13:00:55 1992 Stu Grossman (grossman at cygnus.com)
1669 * Makefile.in (OPCODES): Remove OPCODES defs and refs. There is
1670 no longer any need to copy ../include/opcode/* into gdb.
1672 Mon Jan 27 12:30:38 1992 John Gilmore (gnu at cygnus.com)
1674 * ChangeLog, ChangeLog-9091: Split ChangeLog at 1992.
1676 Sun Jan 26 19:05:40 1992 Per Bothner (bothner at cygnus.com)
1678 * valprint.c (type_print_base, type_print_method_args):
1679 Print C++ constructor methods without bogus "return type."
1681 Sat Jan 25 15:57:59 1992 Fred Fish (fnf at cygnus.com)

1734 for getting custom flags into CFLAGS when doing makes.
1736 * configure.in: Add config information for stratus.

1763 nexting over recursive function calls.
1765 * target.c (target_read_string): Create this routine to read null
1766 terminated strings from the target. It deals with running off the

1789 gatherblocks, make_blockvector): Extensive changes to switch
1790 to generic symbol table building code in buildsym.c. Remove
1791 scope tree structures and functions, symbol table building
1792 functions, and lots of other small changes.

1815 to xm-sysv4.h. Split OPCODE_DIR into OPCODE_DIR1 and OPCODE_DIR2
1816 to reflect actual locations of opcode files, so TAGS target will
