472 (REGISTER_NAMES): Add entries for "right-half" of FP registers.
473 (REGISTER_RAW_SIZE, MAX_REGISTER_RAW_SIZE): Do not treat FP regs
474 differently. All registers are four bytes.
475 (REGISTER_BYTES, REGISTER_BYTE): Simplify now that all registers are
477 (REGISTER_VIRTUAL_TYPE): Use builtin_type_float for all FP regs.
479 * hppa-tdep.c (pa_print_fp_reg): Update to print even numbered FP
480 registers as both single and double values (fetching 2nd 32bit half
481 as necessary). Annotate each register printed with its precision.
483 * paread.c (read_unwind_info): Fix off-by-one error.
485 Fri Mar 25 08:33:28 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
487 * main.c (complete_command): Deal with it if arg is NULL.
489 Thu Mar 24 07:12:09 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
491 * config/mips/tm-mips.h (SETUP_ARBITRARY_FRAME): Revise comment
492 regarding using the PC--using the PC is necessary and all the
493 FIXME comments in the world won't make it go away.
495 * valops.c (value_at, value_at_lazy): Give error if we dereference
497 * gdbtypes.h: Fix comments regarding TYPE_CODE_VOID.
498 * stabsread.c: Use 1, not 0, for TYPE_LENGTH of void types.
500 * stabsread.c (patch_block_stabs): Add comment about what happens
501 if the definition is in another compilation unit from the stab.
503 * dbxread.c (end_psymtab): Add comment about empty psymtabs.
505 Wed Mar 23 07:50:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
507 * main.c (complete_command): New command, from Rick Sladkey
509 (symbol_completion_function): Don't declare rl_point and
510 rl_line_buffer; they are now declared in readline.h.
511 (show_commands): Don't declare history_base; it is declared in
513 * command.c (lookup_cmd): Don't delete trailing whitespace.
514 Reverts change of 14 May 1989.
516 Wed Mar 23 16:14:52 1994 Stu Grossman (grossman at cygnus.com)
518 * minsyms.c (prim_record_minimal_symbol): Move section deduction
519 code from prim_record_minimal_symbol_and_info() to here. Callers
520 of the latter can legitimately supply a section number of -1.
522 Wed Mar 23 07:50:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
524 * gdbtypes.h, gdbtypes.c: Add comments regarding whether static
525 member functions have an element in args for a (nonexistent) this
528 Tue Mar 22 20:12:53 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

536 for the structure's type. All callers changed.
538 * valops.c (call_function_by_hand): Check REG_STRUCT_HAS_ADDR
539 for each structure argument rather than assuming it's either
540 true or false for all structure arguments.
542 * config/pa/tm-hppa.h (REG_STRUCT_HAS_ADDR): Depend only
543 on the length structure passed, not the compiler used.
545 * config/sparc/tm-sparc.h (REG_STRUCT_HAS_ADDR): Accept additional
546 argument for the structure's type.
548 Tue Mar 22 15:28:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
550 * values.c (set_internalvar): Don't set var->value until we are
551 sure there won't be an error().
553 * remote.c (get_offsets): Reinstate comment which was in
554 remote_wait about use of SECT_OFF_TEXT and so on.
556 Mon Mar 21 13:11:30 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
558 * symmisc.c (maintenance_check_symtabs): New function to check
559 consistency of psymtabs and symtabs.

561 * maint.c: Add new `maint check-symtabs' command.
562 * config/i386/tm-i386aix.h, config/i386/tm-sun386.h,
563 config/i386/tm-symmetry.h (REGISTER_CONVERT_TO_RAW): Fix typo.
564 * config/i386/tm-symmetry.h: Make comment inside #if 0 a real
566 * config/i386/tm-symmetry.h (STORE_STRUCT_RETURN): Cast argument
567 to write_memory to avoid warnings from gcc.
568 * config/i386/xm-symmetry.h: Add missing #endif.
569 * config/i386/nm-symmetry.h (NO_PTRACE_H): Add for Dynix.
570 * config/i386/symmetry.mt (TDEPFILES): Add i386-tdep.o.
571 * config/i386/symmetry.mh (NAT_FILE, NATDEPFILES): Add.
573 Mon Mar 21 11:50:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

576 (hppa_push_arguments): Likewise.
578 Mon Mar 21 11:02:51 1994 Stu Grossman (grossman at cygnus.com)
580 * alpha-tdep.c: Gobs of changes (many imported from mips-tdep) to
581 improve remote debugging efficiency. Also fixed problems with
582 doing function calls for programs with no entry points.
583 * infcmd.c (run_stack_dummy): Use CALL_DUMMY_ADDRESS instead of
585 * inferior.h (PC_IN_CALL_DUMMY): ditto.
586 * mdebugread.c (parse_symbol, parse_procedure, parse_external,
587 parse_lines): Pass section_offsets info to these routines so that
588 we can relocate symbol table entries upon readin.
589 * (psymtab_to_symtab_1): Set symtab->primary to tell
590 objfile_relocate to do relocations for our symbols.
591 * (ecoff_relocate_efi): New routine to relocate adr field of PDRs
592 (which hang off of the symbol table).
593 * Use prim_record_minimal_symbols_and_info instead of
594 prim_record_minimal_symbols to supply section info to make minimal
595 symbol relocations work.
596 * minsyms.c (prim_record_minimal_symbols_and_info): If section is
597 -1, try to deduce it from ms_type.
598 * objfiles.c (objfile_relocate): Use ALL_OBJFILE_SYMTABS where
599 appropriate. Handle relocation of MIPS_EFI symbols special. Also,
600 add code to relocate objfile->sections data structure.
601 * remote.c (get_offsets): Use new protocol message to acquire
602 section offsets from the target.
603 * (remote_wait): Get rid of relocation stuff. That's all handled
604 by objfile_relocate now.
605 * config/alpha/alpha-nw.mt (TM_FILE): Use tm-alphanw.h.
606 * config/alpha/tm-alpha.h: Define CALL_DUMMY_ADDRESS, and
608 * config/alpha/tm-alphanw.h: DECR_PC_AFTER_BREAK=0, VM_MIN_ADDRESS=0.
610 Sun Mar 20 15:21:57 1994 Doug Evans (dje@cygnus.com)
612 * sparc-tdep.c (sparc_frame_find_save_regs): Use REGISTER_RAW_SIZE
616 * sp64-tdep.c (target_ptr_bit, set_target_ptr_bit): Deleted,
617 can no longer set this at run time.
618 * config/sparc/sp64.mt (SIMFILES): Use remote-sim.o now.
619 (TM_CLIBS): Define to -lm, the simulator uses the sqrt() function.
620 * config/sparc/tm-sp64.h (FPS_REGNUM, CPS_REGNUM): Define (so
621 sparc-tdep.c compiles).
622 (TARGET_PTR_BIT): Must be a constant now, fix at 64.
625 Sat Mar 19 08:51:12 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
627 * config/m68k/{cisco.mt,tm-cisco.h}: New files.
628 * Makefile.in (ALLPARAM, ALLCONFIG): Add them.
629 * configure.in: Recognize m68*-cisco*-*.
631 * Makefile.in (TAGS): Use variables directly, rather than using
632 find, to locate TM_FILE, XM_FILE, and NAT_FILE. This is faster
633 and means that these filenames no longer need be unique across all
634 the config/* directories.
635 * configure.in: Put the config/*/ into TM_FILE, etc.
637 * m68k-stub.c (computeSignal): Return SIGFPE, not SIGURG, for chk
638 and trapv exceptions.
640 * target.h (struct section_table), objfiles.h (struct obj_section):
641 Change name of field sec_ptr to the_bfd_section. More mnemonic
642 and avoids the (sort of, for the ptx compiler) name clash with
643 the name of the typedef.
644 * exec.c, xcoffexec.c, sparc-tdep.c, rs6000-nat.c, osfsolib.c,
645 solib.c, irix5-nat.c, objfiles.c, remote.c: Change users.
647 * utils.c: Include readline.h.
648 * Makefile.in (utils.o): Add dependency.
650 * remote.c (getpkt): Add support for run-length encoding.
652 Fri Mar 18 19:11:15 1994 Steve Chamberlain (sac@jonny.cygnus.com)
654 * utils.c (prompt_for_continue): Call readline, not gdb_readline.
656 Fri Mar 18 10:25:55 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
658 * dstread.c (record_minimal_symbol): New arg objfile. Pass it to
659 prim_record_minimal_symbol.
662 * regex.c (EXTEND_BUFFER): Adjust pointers within buffer by
663 computing their offset from the start of the old buffer and adding
664 to the new buffer, rather than by assuming we can add the
665 difference between the old buffer and the new buffer (it might not
666 fit in an int). Merge in cosmetic differences from emacs regex.c
667 version of this macro.
669 Wed Mar 16 15:28:54 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
671 * Makefile.in (install-only): Fix use of program_transform_name.
673 Wed Mar 16 07:18:43 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
675 * printcmd.c: Remove "set print fast-symbolic-addr off" command.
676 The bug which it worked around was fixed on 25 Feb 94 in coffread.c,
677 so I'm nuking the command.
678 * symtab.c (find_addr_symbol): Comment out, no longer used.
680 * main.c (main): Don't init_source_path for the -cd argument. Now
681 that source_path doesn't contain the current_directory from when
682 GDB started up, init_source_path is no longer useful (and is
683 harmful because it clobbers a source_path set in $HOME/.gdbinit).
685 * TODO: Remove item about line numbers being off. It is useless
686 and confusing without a reproducible test case (it mentions
687 proceed(), but I was able to step through proceed without trouble).
689 Tue Mar 15 13:39:23 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
691 For Sunos 4.x targets, enable gdb to set breakpoints in shared
692 library functions before the executable is run. Retrieve dynamic
693 symbols from stripped executables.
694 * symtab.h (minimal_symbol_type): Add mst_solib_trampoline type.
695 * parse.c (write_exp_msymbol), symmisc.c (dump_msymbols),
696 symtab.c (list_symbols): Handle mst_solib_trampoline.
697 * minsyms.c (lookup_minimal_symbol): Handle mst_solib_trampoline
698 for all targets, remove IBM6000_TARGET dependencies.
699 * dbxread.c (read_dbx_dynamic_symtab): New function.
700 * dbxread.c (dbx_symfile_read): Use it.
701 * dbxread.c (SET_NAMESTRING): Set namestring to
702 "<bad string table index>" instead of "foo" if the string index is
704 * xcoffread.c (read_xcoff_symtab): Use mst_solib_trampoline instead
706 * symtab.c (list_symbols): Take from_tty as parameter and pass it
707 to break_command. Handle mst_file_* minimal symbol types.
708 * config/i386/tm-i386bsd.h: Give just macro name, not args, to #undef.
710 Tue Mar 15 11:40:43 1994 Kung Hsu (kung@mexican.cygnus.com)

714 Tue Mar 15 10:33:28 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
716 * environ.c (set_in_environ): Eliminate special handling of PATH and
718 * putenv.c: Removed, conflicts with system declaration of
719 putenv on RS/6000 running AIX 3.2.5, and above change makes it
721 * Makefile.in: Change accordingly.
722 * procfs.c (procfs_create_inferior): Change comment accordingly.
724 Tue Mar 15 10:05:27 1994 Jim Kingdon (kingdon@cygnus.com)

728 Sun Mar 13 09:45:51 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
730 * i386m3-nat.c: Include floatformat.h.
731 (get_i387_state): Use memset not bzero.
735 * Makefile.in: Enable commented out getopt_h, bfd_h, etc. Change
736 ieee-float.h to floatformat.h.
738 * valprint.c (val_print_string): Ignore error if the error
739 happened after a terminating '\0'.
741 * c-valprint.c (c_val_print): Never add 1 to return value from
742 val_print_string; just return what it returns.
744 * target.h (enum target_signal): Add TARGET_SIGNAL_FIRST, for
745 looping through all of the enums.
746 * infrun.c (signals_info): Use it.
748 Fri Mar 11 08:08:50 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
750 * main.c (main): When printing warning about bad baud rate, don't
751 use warning(); it relies on current_target which isn't set up yet.
753 * breakpoint.c (_initialize_breakpoint): Update docstring for
754 tbreak to match what the code actually does. Don't mention tbreak
755 in docstrings for "enable once" or "enable breakpoints once".
757 Thu Mar 10 08:52:38 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
759 * symfile.h (ADD_PSYMBOL_VT_TO_LIST): Don't put a semicolon after
760 while (0). That defeats the whole purpose of using do . . . while (0).
761 * mdebugread.c (parse_partial_symbols): Don't use ?: expression as
762 list for ADD_PSYMBOL_TO_LIST; the macro takes its address and
763 using a ?: expression as an lvalue is not portable.
765 * stabsread.c (define_symbol): If REG_STRUCT_HAS_ADDR, also
766 convert a LOC_ARG to a LOC_REF_ARG. Update code which combines
767 'p' and 'r' symbol descriptors into a single symbol to look for a
769 * README, config/sparc/tm-sparc.h: Update comments.
771 Wed Mar 9 21:43:24 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
773 * mdebugread.c (parse_type): Do not complain for types with
774 an `indexNil' aux index, these are simply undefined types.
775 Remove indexNil check from caller of parse_type.
776 * mdebugread.c (parse_partial_symbols): Do not enter
777 stGlobal, scCommon symbols into the minimal symbol table, their
778 value is the size of the common, not its address.
779 Handle scInit, scFini, scPData and scXData sections.
780 Use minimal symbol type mst_file_* for stLabel symbols, instead of
782 Enter stProc symbols into the global_psymbols list once, not into
783 the static_psymbols_list.
784 Get rid of dummy psymtab if it is empty, to allow proper detection
785 of stripped executables.
786 * mdebugread.c (cross_ref): Allow cross references to Fortran
789 Wed Mar 9 15:23:19 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
791 * stabsread.c (common_block_end, fix_common_block): Stash the
792 struct pending * in the SYMBOL_TYPE, not the SYMBOL_NAMESPACE, so
793 as to not assume that a pointer fits in an enum.
795 Wed Mar 9 18:56:36 1994 Kung Hsu (kung@mexican.cygnus.com)
797 * os9kread.c (fill_sym): check compiler verion number for pre-
799 * os9kread.c (os9k_process_one_symbol): address of symbol is
800 relative to section not module.
801 * stabsread.c (define_symbol): add symbol type 's' as local
803 * remote-os9k.c: add command 'set monitor_log' to turn on or off
805 * remote-os9k.c: fix bug in delete breakpoint, single step trace.
806 * remote-os9k.c: fix bug in 'set remotebaud' function.
807 * remote-os9k.c (rombug_link): minimize checking so to improve
809 * symfile.c (symbol_file_command): check if failed to link, also make
810 the command be able to accept more than one filenames.
811 * target.c (target_link): check if failed to link with rombug.
812 * config/i386/tm-i386os9k.h : add #define DECR_PC_AFTER_BREAK 0.
814 Wed Mar 9 15:23:19 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
816 * remote-es.c (es1800_child_ops): Don't declare it static.
818 Tue Mar 8 11:42:39 1994 Jim Kingdon (kingdon@cygnus.com)
820 * config/i386/tm-i386v4.h: Give just macro name, not args, to #undef.

825 (record_minimal_symbol, read_dbx_symtab): Set it.
826 (read_dbx_symtab): Use lowest_text_address + text_size instead of
828 * config/gould/tm-pn.h: Add comment regarding END_OF_TEXT_DEFAULT.
830 * dbxread.c (end_psymtab): Remove old and commented out
831 capping_global and capping_static. Fix comments regarding
832 N_SO_ADDRESS_MAYBE_MISSING to match the real name of the macro.
834 * parser-defs.h: Add "extern" to start of variable declarations so
835 we don't end up with commons.
836 * parse.c: Define these variables.
838 * irix5-nat.c (find_solib): Cast o_path to CORE_ADDR when using it
841 Mon Mar 7 13:00:50 1994 Jim Kingdon (kingdon@lioth.cygnus.com)

845 Sun Mar 6 17:36:53 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
847 * solib.c (elf_locate_base): New function to locate the address
848 of the dynamic linker's runtime structure in the dynamic info section.
849 * solib.c (locate_base): Use it instead of iterating over the list
850 of mapped address segments.

874 alphabetic character as the start of a name.
876 * sparclite/Makefile.in (all install): Build and install aload.
878 * configure.in: Accept i[34]86-*-*sysv32 because that is what
879 config.guess and config.sub produce.
881 * mips-tdep.c: Change value to value_ptr.
883 Wed Mar 2 09:17:55 1994 Jim Kingdon (kingdon@deneb.cygnus.com)

888 valarith.c, valops.c, valprint.c, value.h, values.c: Replace
889 value with value_ptr. This is for the ptx compiler.
890 * objfiles.h, target.h: Don't declare a "sec_ptr" field using a
892 * symm-nat.c: Add a bunch of stuff for symmetry's ptrace stuff.
893 #if 0 i386_float_info.
894 * symm-tdep.c (round): Remove. Also remove sgttyb.
895 * symm-tdep.c: Remove lots of stuff which duplicates stuff from

897 * i386-tdep.c (i386_frame_find_saved_regs): Put in
898 I386_REGNO_TO_SYMMETRY check in case it is needed for Dynix

902 symm-nat.c. Define CHILD_WAIT and declare child_wait().
903 * config/i386/tm-symmetry.h: Remove call function stuff; stuff in
904 tm-i386v.h is apparently OK.
905 * config/i386/xm-symmetry.h [_SEQUENT_]: Define HAVE_TERMIOS not
906 HAVE_TERMIO. Define MEM_FNS_DECLARED, NEED_POSIX_SETPGID, and

911 * osfsolib.c (xfer_link_map_member): Update to use new
912 target_read_string interface.
914 Wed Mar 2 09:17:55 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
916 * infrun.c (wait_for_inferior): In checking
917 remove_breakpoints_on_following_step, check
918 through_sigtramp_breakpoint as well as step_resume_breakpoint.
920 Tue Mar 1 16:22:56 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
922 * os9kread.c (os9k_process_one_symbol): Rename
923 VARIABLES_INSIDE_BLOCK to OS9K_VARIABLES_INSIDE_BLOCK.
924 * symfile.c (symbol_file_command): Check for (CORE_ADDR)-1, not
925 (CORE_ADDR)0, from target_link, since that is what it uses.
926 Process name at end, not during parsing (like we did before Kung's
927 change), so that -readnow and -mapped can appear anywhere.
928 Make text_relocation a local variable.
929 * config/i386/i386os9k.mt: Fix comment.
930 * Makefile.in (ALLDEPFILES): Add remote-os9k.c.
931 * os9kread.c: Put "comments" after #endif inside /* */.
932 * stabsread.h: Add os9k_stabs variable.
933 * stabsread.c (start_stabs), os9kread.c (os9k_process_one_symbol):
935 * stabsread.c (define_symbol): If os9k_stabs, put a 'V' symbol
936 descriptor in global_symbols not local_symbols.

1068 step_resume_breakpoint, use the through_sigtramp_breakpoint, or
1070 Deal with BPSTAT_WHAT_THROUGH_SIGTRAMP return from bpstat_what.
1071 When setting the frame address of the step resume breakpoint, set

1369 Thu Feb 3 12:38:58 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1371 * m68k-stub.c: Treat mc68332 like mc68020 most places. Provide
1372 a special exceptionSize for the 68332.
1374 * remote-udi.c (udi_attach): If no arguments, print error.
1376 Thu Feb 3 17:34:05 1994 Fred Fish (fnf@cygnus.com)
1378 * Makefile.in (VERSION): Bump to 4.12.1
1379 * NEWS, README: Update to match 4.12 release.
1381 Thu Feb 3 12:38:58 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1383 * command.c (empty_sfunc): New function.
1384 (add_set_cmd): Use it instead of not_just_help_class_command.
1385 (not_just_help_class_command): Change calling convention back to
1386 what it was before yesterday's change.
1388 * stabsread.c (read_sun_builtin_type): Skip the semicolon at the end
1389 of the type if present.
1391 Wed Feb 2 11:16:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1393 * printcmd.c (decode_format): Don't blithely set the size for
1394 an address to 'w'. Make it 'g' or 'h', depending on TARGET_PTR_BIT.
1396 * defs.h: Just typedef CORE_ADDR to bfd_vma. Include bfd.h.
1397 If BFD64, make a LONGEST a BFD_HOST_64_BIT.
1398 * defs.h (longest_to_int): Don't depend on CC_HAS_LONG_LONG; instead
1399 always just check against INT_MIN and INT_MAX (this also fixes things
1400 if sizeof (long) > sizeof (int), e.g. Alpha).
1401 * config/pa/tm-hppa.h, config/i386/sun386.h, config/rs6000/tm-rs6000.h:
1402 Don't define LONGEST or BUILTIN_TYPE_LONGEST.
1403 * gdbtypes.h: Remove BUILTIN_TYPE_LONGEST and
1404 BUILTIN_TYPE_UNSIGNED_LONGEST.
1405 * language.h, c-lang.c, ch-lang.c, m2-lang.c, language.c: Remove
1406 longest_int and longest_unsigned_int.
1407 * value.h (struct value): Just align to LONGEST, rather than worrying
1408 about CC_HAS_LONG_LONG.
1409 * valarith.c (value_binop): Figure out type ourself based on
1410 sizeof (LONGEST) rather than relying on BUILTIN_TYPE_LONGEST. The
1411 point is that we don't depend on CC_HAS_LONG_LONG anymore.
1412 * valprint.c (val_print_type_code_int): Just call
1413 extract_unsigned_integer directly, rather than going through
1415 * printcmd.c (decode_format): Remove code which would sometimes
1416 change 'g' size to 'w' for integers. print_scalar_formatted handles
1417 printing huge integers well enough, thank you.
1419 * command.c (add_set_cmd, not_just_help_class_command): Change
1420 to make this the sfunc, not cfunc, since that is how we call it.
1421 * command.h: Comment difference between sfunc and cfunc.
1422 * demangle.c (set_demangling_command): Add third arg since that
1423 is how it is called.
1424 (_initialize_demangler): Use sfunc, not cfunc, for
1425 set_demangling_command, since that is how it is called.
1426 Remove show_demangling_command; it has no effect.
1428 * command.c (shell_escape): Report errors correctly (with error
1429 message from strerror).
1431 Wed Feb 2 14:35:41 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1433 * xcoffread.c (read_xcoff_symtab): Change CSECT_LEN to use
1434 x_scnlen.l rather than x_scnlen to match corresponding change in
1437 Wed Feb 2 11:16:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1439 * gdbtypes.h, ch-typeprint.c, ch-valprint.c:
1440 Change comments regarding TYPE_CODE_BOOL.
1441 * language.c (boolean_type): Always return 1 for TYPE_CODE_BOOL,
1442 regardless of the language.
1443 (value_true): Just call value_logical_not regardless of language.
1444 * coffread.c (coff_read_enum_type), stabsread.c (read_enum_type):
1445 Remove #if 0'd code which makes some enums TYPE_CODE_BOOL.
1446 * language.h: Improve comment for la_builtin_type_vector.
1447 * m2-lang.c (_initialize_m2_language): Don't add any fields to
1448 builtin_type_m2_bool.
1450 Tue Feb 1 17:13:32 1994 Kevin Buettner (kev@cujo.geg.mot.com)
1452 * config/m88k/{tm-delta88.h,tm-delta88v4.h}, m88k-tdep.c:
1453 Define IN_SIGTRAMP and backtrace correctly through signal handlers.
1455 Tue Feb 1 22:13:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1457 * procfs.c (wait_fd): Handle EINTR error return from PIOCWSTOP ioctl
1458 by restarting the ioctl.
1460 Tue Feb 1 16:16:25 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1462 * target.h (target_wait): Add comment about calling
1463 return_to_top_level.
1465 Tue Feb 1 12:21:00 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1467 * coffread.c (read_one_sym): bfd_coff_swap_aux_in now takes
1468 additional arguments.
1469 * xcoffread.c (read_xcoff_symtab, read_symbol_lineno): Likewise.
1471 Mon Jan 31 16:10:41 1994 Stu Grossman (grossman at cygnus.com)
1473 * sparc-stub.c: Remove unnecessary #include of memory.h.
1475 Mon Jan 31 12:12:34 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1477 * mips-tdep.c: Remove code which sets saved_regs from
1478 init_extra_frame_info and put it in new function mips_find_saved_regs.
1479 (READ_FRAME_REG): Remove macro and replace uses with the expansion.
1480 * mips-tdep.c, config/mips/tm-mips.h: When examining ->saved_regs,
1481 check if it is NULL and call mips_find_saved_regs if so.
1483 * remote-mips.c: Use unfiltered, not filtered, output most places.
1485 * blockframe.c (get_prev_frame_info): Detect and stop an infinite
1486 backtrace. Revise comments.
1488 Mon Jan 31 09:40:33 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1490 * mdebugread.c (parse_procedure): Remove _sigtramp kludges for
1491 alpha and irix. The _sigtramp case has to be handled properly
1492 in the tdep files if we have no ecoff debugging info.
1493 * alpha-tdep.c (alpha_frame_saved_pc, alpha_frame_chain),
1494 mips-tdep.c (mips_frame_saved_pc): Handle signal handler frames
1495 without PC_REGNUM kludge.
1496 * mdebugread.c (fixup_sigtramp), mips-tdep.c (read_next_frame_reg):
1497 Clean up handling of mips sigtramp frames, improve comments.
1499 Sat Jan 29 23:25:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1501 * paread.c (read_unwind_info): Fix typo.
1503 * paread.c (pa_symtab_read): Update the "check_strange_names"
1504 filter to match GCC's current output. Filter out section symbols
1505 (which the HP linker sometimes puts in the wrong place).
1507 Sat Jan 29 07:44:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
1509 * serial.h (SERIAL_SET_TTY_STATE): Comment return value.
1511 * Makefile.in (TAGS): Just echo one line, rather than the whole thing.
1513 * Makefile.in: Remove all references to sparcly-nat.c.
1515 * Makefile.in (HFILES_NO_SRCDIR): Include dcache.h remote-utils.h
1516 remote-sim.h directly, rather than via $(remote_utils_h). This avoids
1517 duplicating serial.h and target.h.
1519 * Makefile.in: Don't set M_INSTALL and M_UNINSTALL. These variables
1520 are not used anywhere (a 5 Oct 1993 change removed the uses).
1522 * config/m68k/monitor.mt (TDEPFILE): Add remote-es.o.
1523 * config/m68k/es1800.mt: Add comment.
1524 * remote-es.c: Extensive changes to update to current conventions.
1526 * ser-unix.c (wait_for, hardwire_readchar) [HAVE_TERMIO, HAVE_TERMIOS]:
1527 If the timeout is too big to fit in c_cc[VTIME], then do multiple reads
1528 to achieve the desired timeout.
1529 * serial.h (serial_t): Add field timeout_remaining.
1531 Fri Jan 28 08:45:02 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
1533 * c-exp.y (yylex): Reenable nested type code.
1535 Fri Jan 28 15:40:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1537 * a29k-tdep.c (examine_tag): Add comment regarding argcount.
1539 * remote-mips.c (mips_ops): Fix docstring.
1541 * remote-bug.c (bug_ops): Remove spurious newline from docstring.
1543 * config/m68k/tm-monitor.h: Changes to bring this into accordance
1544 with the old tm-m68k-em.h:
1545 (GDBINIT_FILENAME, DEFAULT_PROMPT): Remove.
1546 (HAVE_68881): Don't undefine; HAVE_68881 is obsolete.
1547 (REGISTER_NAMES): Don't muck with it; what tm-m68k.h has is fine.
1548 Add FIXME regarding GET_LONGJMP_TARGET.
1550 * remote-udi.c (udi_close, udi_detach, udi_kill): Add comments.
1551 * infptrace.c (kill_inferior): Add comments.
1552 * main.c (quit_command): Call target_close after we kill or
1554 * remote-udi.c (udi_close): Don't error() if QUITTING.
1556 Fri Jan 28 11:55:52 1994 Rob Savoye (rob@darkstar.cygnus.com)
1558 * configure.in: Make m68k-coff and aout add monitor support in
1559 addition to the standard serial support.
1561 Fri Jan 28 08:45:02 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
1563 * mdebugread.c (psymtab_to_symtab_1): Don't complain on stLabel with
1566 Fri Jan 28 10:40:34 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1568 * config/pa/tm-hppa.h: Define macro SMASH_TEXT_ADDRESS.
1569 * elfread.c (record_minimal_symbol_and_info),
1570 dwarfread.c (process_dies), paread.c (pa_symtab_read): Use it.
1572 Thu Jan 27 15:12:23 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1574 * i386-stub.c: Add ".text" right before "mem_fault:".
1576 * main.c (baud_rate): Add FIXME comment about printing -1 value.
1578 * remote-utils.c (usage): Fix message to be accurate and conform
1579 more closely to normal conventions.
1581 * remote-utils.c (gr_files_info): Have the exec_bfd test control
1582 whether to show information about exec_bfd, and not control whether
1583 to show information about device and speed.
1585 * remote-utils.c (gr_open): If sr_get_device returns NULL, give
1586 usage message, don't dump core.
1588 * remote-bug.c (bug_write_memory): Use alloca, not GCC extension
1589 for variable size array.
1590 (bug_fetch_register, bug_store_register): Rename "value" to
1591 "fpreg_buf" because some compilers don't like variables whose
1592 names are the same as types.
1593 (bug_store_register): Use a cast when converting char * to
1596 * symmisc.c (maintenance_print_symbols): Don't refer to the name
1597 of the command in error message (the text was referring to the old
1598 name of the command).
1600 * symmisc.c (dump_symtab): Fix args to fprintf_filtered.
1602 * c-typeprint.c (c_type_print_base): Have SHOW == 0 mean to print
1603 full details on structure elements without names. This partially
1604 reverts the changes of 1 Jul 1993 and 31 Aug 1993; I think this aspect
1605 of those changes was accidental.
1607 * stack.c (parse_frame_specification): If SETUP_ARBITRARY_FRAME is
1608 defined, make it an error to specify a single argument which is not
1611 * Makefile.in (version.c), main.c (print_gdb_version): Use
1612 host_alias and target_alias, not host_canonical and
1613 target_canonical, to print configuration.
1615 Wed Jan 26 10:57:21 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1617 * parse.c (write_exp_msymbol): Use new type msymbol_addr_type instead
1618 of builtin_type_long. It is necessary to get a type which is
1619 TARGET_PTR_BIT bits in size; builtin_type_long might not be big enough.
1621 Fix many sins which will come up in 32 bit x 64 bit GDB, and
1622 various miscellaneous things discovered in the process:
1623 * printcmd.c, defs.h (print_address_numeric): New function.
1624 * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print)
1625 breakpoint.c (describe_other_breakpoints, breakpoint_1, mention),
1626 cp-valprint.c (cplus_print_value), infcmd.c (jump_command),
1627 printcmd.c, stack.c, symfile.c, symmisc.c, valprint.c:
1629 * utils.c, defs.h (gdb_print_address): New function.
1630 * expprint (dump_expression), gdbtypes.h: Use it.
1631 * breakpoint.c (describe_other_breakpoints),
1632 symmisc.c (dump_symtab, print_symbol):
1633 Use filtered not unfiltered I/O.
1634 (remove_breakpoints): Remove BREAKPOINT_DEBUG code. Might as well
1635 just run gdb under a debugger for this (and it had problems with
1636 printing addresses, how to print b->shadow, etc.).
1637 * buildsym.c (make_blockvector), core.c (memory_error),
1638 exec.c (print_section_info), maint.c (print_section_table),
1639 mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
1640 symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
1641 Add comments saying code is broken. Marked with "FIXME-32x64".
1642 * dbxread.c (process_one_symbol), partial-stab.h (default),
1643 remote-vx.c (vx_run_files_info):
1644 Don't cast int being passed to local_hex_string.
1645 * symmisc.c (print_symbol): Don't cast long being passed to %lx.
1646 * symtab.h (general_symbol_info): Add comment about SYMBOL_VALUE
1648 * symmisc.c (print_symbol): Print "offset" in message for LOC_ARG
1650 * printcmd.c (print_address): Remove #if 0 code with ADDR_BITS_REMOVE.
1651 * source.c: Include <sys/types.h> regardless of USG.
1653 Tue Jan 25 12:58:26 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1655 * valops.c (value_assign): Set `type' after coercing toval.
1656 * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print):
1657 Use extract_unsigned_integer to get the address of a reference.
1659 Tue Jan 25 11:31:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1661 * stabsread.c (STABS_CONTINUE, error_type), partial-stab.h:
1662 AIX can use ? instead of \ for continuation. Deal with it.
1664 * paread.c (read_unwind_info): Just assign to objfile->obj_private,
1665 not OBJ_UNWIND_INFO. Assigning to a cast is a GCC-ism which
1666 the HP compiler in ANSI mode doesn't like.
1668 * main.c: When defaulting HAVE_SIGSETMASK based on USG, just do it
1669 based on USG, rather than defining HAVE_SIGSETMASK to an
1670 expression containing defined. Having a macro used in #if expand
1671 to an expression containing "defined" is undefined according to
1672 ANSI, and the HP compiler in ANSI mode doesn't do what we wanted
1675 Mon Jan 24 20:51:29 1994 John Gilmore (gnu@cygnus.com)
1677 * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
1678 Clean up the changes of 11 Jan, as recommended by Peter Schauer.
1680 Fri Jan 21 19:10:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
1682 * ch-exp.y (match_string_literal): Allow a zero-length string.
1683 * ch-lang.c (chill_printstr): Don't print zero-length string funny.
1685 Sat Jan 22 17:08:48 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1687 * i386aix-nat.c (i386_float_info): Reverse order of registers before
1688 passing them to print_387_status.
1689 (print_387_status): Don't subtract top from 7 before using it.
1690 * i387-tdep.c: Remove comment about AIX wanting "top" subtracted
1691 from 7; the above explains it.
1693 Sat Jan 22 20:25:11 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1695 * mips-tdep.c (init_extra_frame_info): Use frame relative stack
1696 pointer value when fixing up the frame at the start of a function.
1698 Sat Jan 22 12:29:13 1994 Stu Grossman (grossman at cygnus.com)
1700 * lynx-nat.c (fetch_core_registers): Load the I & L regs for the
1701 Sparc from the stack.
1703 Sat Jan 22 08:30:42 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
1705 * remote-mips.c (mips_initialize): Clear mips_initializing via
1706 cleanup chain, not directly.
1708 * ser-unix.c (wait_for) [HAVE_TERMIO, HAVE_TERMIOS]: Make a timeout
1709 of -1 mean forever, like in the HAVE_SGTTY case. Warn if we are
1710 munging the timeout due to the limited range of c_cc[VTIME].
1712 * fork-child.c, inferior.h (fork_inferior): New argument shell_file.
1713 * procfs.c (procfs_create_inferior), inftarg.c (child_create_inferior),
1714 m3-nat.c (m3_create_inferior): Pass it.
1715 * procfs.c: Remove ptrace function. It was declared in a way which
1716 conflicted with the prototype in unistd.h on Solaris.
1718 Sat Jan 22 01:37:40 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1720 * sparc-tdep.c (frame_saved_pc): Get the pc from the saved pc
1721 in the sigcontext if it is a signal trampoline frame.
1722 * config/sparc/tm-sun4sol2.h (IN_SIGTRAMP, SIGCONTEXT_PC_OFFSET):
1723 Define for Solaris2.
1725 Sat Jan 22 00:34:47 1994 Stu Grossman (grossman at cygnus.com)
1727 * sparc-tdep.c, lynx-nat.c, config/sparc/tm-sparc.h,
1728 config/sparc/tm-sparclynx.h: Move defs of FRAME_SAVED_I0/L0 to
1729 tm-sparc.h so they can be overridden if necessary.
1731 Fri Jan 21 17:49:28 1994 Stu Grossman (grossman at cygnus.com)
1733 * lynx-nat.c: Add Sparc support.
1734 * sparcly-nat.c: Remove. It's useless.
1735 * config/sparc/nm-sparclynx.h: Rewrite.
1736 * config/sparc/sparclynx.mh (NATDEPFILES): Replace sparcly-nat.o
1738 * config/sparc/tm-sparclynx.h: Rewrite.
1740 Fri Jan 21 19:08:48 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1742 * rs6000-pinsn.c: Use the new disassembler in the opcodes
1743 directory. Old code was discarded, since the new opcode table has
1746 Fri Jan 21 14:28:30 1994 Fred Fish (fnf@cygnus.com)
1748 * Makefile.in (realclean): Remove info files per make-stds.texi.
1750 Fri Jan 21 12:47:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1752 * dbxread.c (end_psymtab): Only patch psymtab textlow and texthigh
1753 if N_SO_ADDRESS_MAYBE_MISSING is defined.
1754 * config/sparc/tm-sun4sol2.h: Define it.
1756 Thu Jan 20 15:04:24 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1758 * printcmd.c (print_address_symbolic): Unconditionally use msymbol
1759 if we did not find a symbol.
1761 Fri Jan 21 08:20:18 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1763 * infptrace.c (child_xfer_memory): Only use if CHILD_XFER_MEMORY
1766 * hppab-nat.c (call_ptrace): Delete redundant function.
1767 (kill_inferior, attach, detach, child_resume): Likewise.
1768 (child_xfer_memory): Likewise.
1770 * hppah-nat.c (call_ptrace): Delete redundant function.
1771 (kill_inferior, attach, detach, child_resume): Likewise.
1773 * config/pa/hppabsd.mh (NATDEPFILES): Add infptrace.o.
1775 * config/pa/hppahpux.mh (NATDEPFILES): Add infptrace.o.
1777 * config/pa/nm-hppab.h (FETCH_INFERIOR_REGISTERS): Define.
1779 * config/pa/nm-hppah.h (FETCH_INFERIOR_REGISTERS): define.
1780 (CHILD_XFER_MEMORY): Define.
1781 (PT_*): Define so that generic infptrace.c code can be used.
1783 Fri Jan 21 09:23:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1785 * xcoffread.c (xcoff_symfile_read): Make second parameter a
1786 struct section_offsets *, not a (nonexistent) struct section_offset *.
1788 * xcoffread.c (read_xcoff_symtab): Make main_aux just a union
1789 internal_xcoff_symtab, not an array of one of them. Change lots of
1790 "main_aux" to "&main_aux" and so on.
1792 * coffread.c, xcoffread.c: Include <coff/internal.h>
1795 Thu Jan 20 17:30:55 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1797 * coffread.c (coff_getfilename): Make it not static.
1799 * xcoffread.c (read_xcoff_symtab): complain() not abort().
1801 * xcoffread.c (struct coff_symbol): Rename c_nsyms to c_naux (removes
1802 a completely gratuitous difference between xcoffread.c and coffread.c).
1804 Wed Jan 19 15:09:44 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1806 * infrun.c (wait_for_inferior): Don't set frame for
1807 step_resume_breakpoint for IN_SIGTRAMP cases.
1809 * infrun.c (wait_for_inferior), breakpoint.h (struct bpstat_what),
1810 breakpoint.c (bpstat_what): Move step_resume from its own field of
1811 the struct bpstat_what into the main_action. Make it override
1812 other breakpoints. This is a conservative change in the sense
1813 that before the step resume breakpoint was a breakpoint.c
1814 breakpoint, hitting the step resume breakpoint overrode even
1815 calling bpstat_stop_status.

1819 * infrun.c (normal_stop): Set stop_pc after popping the dummy frame
1820 in case execution was stopped in the called function.
1821 * stack.c (print_frame_info, frame_info): If backtracing through
1822 a call dummy, handle the starting source line number on a line
1823 boundary like backtracing through sigtramp.
1824 * sparc-tdep.c (sparc_frame_find_saved_regs): Get frame address
1825 for call dummy frame right. Remove old test for dummy frame,
1826 it has been unused at least since gdb-3.5.

1859 * paread.c (compare_unwind_entries): New function for sorting
1860 unwind table entries.
1861 (read_unwind_info): Rewrite to remove dependency on host endianness.
1862 Read in data from the $UNWIND_END$ subspace which contains linker
1863 stub unwind descriptors. Merge that data into the basic unwind
1866 * hppab-nat.c (_initialize_kernel_u_addr): Delete unwanted functions.
1868 Mon Jan 17 22:00:15 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1870 * xcoffread.c (read_xcoff_symtab, case C_FILE): Accept the name
1871 from either the symbol name or the auxent.
1872 * coffread.c, symfile.h (coff_getfilename): Renamed from getfilename,
1875 Mon Jan 17 13:35:01 1994 Fred Fish (fnf@cygnus.com)

1892 * c-exp.y (parse_number): Assign to temporary between the right
1893 shifts, to work around a bug in the SCO compiler.

1907 Sat Jan 15 18:27:34 1994 Per Bothner (bothner@kalessin.cygnus.com)
1909 * main.c (show_commands): Make return type of extern
1910 history_get be HIST_ENTRY, rather than struct _hist_entry.
1911 (The latter loses with the upcoming merged readline.)
1913 Sat Jan 15 10:20:13 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1915 * minsyms.c (prim_record_minimal_symbol_and_info): Make tempstring

1922 * utils.c (fputs_unfiltered): Call fputs, not fputs_maybe_filtered.
1924 * c-exp.y (parse_number): Check for overflow regardless of range
1925 checking. Fix overflow check to use unsigned LONGEST, not
1928 * c-exp.y (parse_number): Make it so that integer constants are
1929 builtin_type_long_long if builtin_type_long isn't big enough or if
1930 an "LL" suffix is used. Properly handle "UL" or "LU" suffixes.
1932 * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
1933 Print our "()" first, then recurse for the target type.
1935 Fri Jan 14 21:55:39 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1937 * remote-udi.c (udi_create_inferior): Quote empty execfile argument.
1939 * gdbserver/low-lynx.c: Include <sys/wait.h> not "/usr/include/wait.h".
1941 Fri Jan 14 14:17:06 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1943 * utils.c (request_quit): Re-establish signal handler regardless
1946 * config/mips/xm-irix4.h: Define HAVE_TERMIOS.
1948 Fri Jan 14 21:55:39 1994 Jim Kingdon (kingdon@lioth.cygnus.com)

1952 Fri Jan 14 17:12:28 1994 Stan Shebs (shebs@andros.cygnus.com)
1954 * lynx-nat.c (sys/wait.h): Don't use absolute pathname.
1956 Fri Jan 14 11:06:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
1958 * lynx-nat.c (child_wait): Fix thinkos in struct target_waitstatus
1959 changes (status -> ourstatus; declare status, etc.).
1960 * config/nm-lynx.h: Fix child_wait prototype and include target.h.
1962 Fri Jan 14 14:17:06 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1964 * Makefile.in (ALLPARAM): Add config/nm-lynx.h.
1966 Fri Jan 14 11:49:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1968 * remote-mips.c (mips_request, mips_wait): Correct prototypes.

1972 * config/i386/xm-linux.h: Define HAVE_TERMIOS.
1974 Fri Jan 14 01:04:36 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)

1980 * remote-vx.c (vx_wait): Only call i960_fault_to_signal if I80960
1981 is defined. Otherwise just report TARGET_SIGNAL_UNKNOWN.
1983 * mips-tdep.c (mips_push_arguments): Byteswap struct_addr before
1986 Add search to target vector (#if 0'd until after 4.12):
1987 * target.h (to_search, target_search): Add.
1988 * gdbcore.h, core.c (generic_search): Add.
1989 * remote.c (remote_search): Add.
1990 * a29k-tdep.c (init_frame_info): Use target_search to find traceback
1993 * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
1994 is on, call find_pc_function rather than relying just on the minimal
1995 symbols (probably only matters for symbol readers which don't put
1996 statics in the minimal symbols, but changing this strikes me as
1997 not conservative enough).
1998 Initialize name_location in all cases.
1999 If no symbol and no msymbol, don't print anything symbolic.
2001 * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
2003 Wed Jan 12 20:53:16 1994 John Gilmore (gnu@cygnus.com)
2005 * printcmd.c (print_address_symbolic): Make it search the
2006 symtabs for variables as well as functions. Add `set print
2007 fast-symbolic-addr' and default it to fast (the old way).
2008 Print line numbers for data items as well as functions.
2010 * symtab.c (find_addr_symbol): Return the symtab and the symbol
2011 address, if a symbol is found (take two more args pointing to
2012 where to store these results).
2014 * symtab.h (find_addr_symbol): Add prototype.
2016 Wed Jan 12 19:32:11 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2018 * objfiles.h: Fix comments to reflect the fact that the phrase
2019 "top of stack" always refers to where the pushing and popping takes
2020 place, regardless of whether it is at the highest or lowest address.
2022 Wed Jan 12 13:23:37 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2024 * mdebugread.c (parse_symbol): Do not set TYPE_TAG_NAME for
2025 compiler generated tag names.
2026 * mdebugread.c (parse_type): Handle cross references to qualified
2028 * valops.c (value_struct_elt): Improve error message if the
2029 address of a method is requested from an object instance.
2030 * valops.c (search_struct_method): Make name_matched non-static
2031 to get it initialized correctly.
2032 * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER): Define to
2033 exclude segment register which are not writable on newer SCO versions.
2035 Wed Jan 12 14:44:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2037 * go32-xdep.c: Remove unused function uerror.
2038 (sigsetmask): Declare return type. Declare argument (to match the
2039 way it is called). Explicitly return 0.
2041 Wed Jan 12 01:44:25 1994 John Gilmore (gnu@cygnus.com)
2043 * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
2044 partial_symbol): Shrink the storage sizes of symbols, by making
2045 enums into 1-byte bitfields when compiled __GNUC__, moving all the
2046 enums and small ints to the end of each struct to improve
2047 alignment, and switching the section number from int to unsigned
2050 Wed Jan 12 00:16:26 1994 John Gilmore (gnu@cygnus.com)
2052 * symtab.c (find_addr_symbol): New routine that will find the nearest
2053 symbol associated with an address. It does so by exhaustive
2054 search of the symtabs, so it's slow but complete.
2056 Tue Jan 11 23:57:30 1994 John Gilmore (gnu@cygnus.com)
2058 * coffread.c (read_coff_symtab): Set PC bounds of _globals_ symtab
2059 to [0,0] rather than [0, end of first source file]. This avoids
2060 problems with other parts of GDB looking for linetables in the
2061 _globals_ symtab. Eliminate variables num_object_files and
2062 first_object_file_end.
2064 Tue Jan 11 00:53:46 1994 John Gilmore (gnu@cygnus.com)
2066 * a29k-tdep.c (init_frame_info): Cast null arg to examine_tag.
2067 (pop_frame): Restore PC2 and LR0 from dummy frames.
2068 (push_dummy_frame): Save PC2 and LR0 into dummy frames.
2069 (setup_arbitrary_frame): Handle 3 args and set up real frames.
2070 * config/a29k/tm-a29k.h (FRAME_NUM_ARGS): Update comments.
2071 (DUMMY_FRAME_RSIZE): Add 2 longwords for PC2 and LR0.
2072 (SETUP_ARBITRARY_FRAME): Define.
2074 Tue Jan 11 06:59:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2076 * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
2078 Tue Jan 11 14:27:03 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2080 * remote-udi.c (udi_resume): Correct prototype.
2082 Tue Jan 11 11:10:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2084 * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
2085 hppa_frame_find_saved_regs.
2086 * hppa-tdep.c (dig_fp_from_stack): Delete function.
2087 (prologue_inst_adjust_sp): New function.
2088 (is_branch, inst_saves_gr, inst_saves_fr): New functions.
2089 (skip_prologue): Completely rewrite to use unwind information.
2090 (hppa_frame_find_saved_regs): Likewise.
2092 Tue Jan 11 06:59:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2094 * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
2095 to convert a signal number with appropriate bounds checking.
2097 * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
2099 Tue Jan 11 00:53:46 1994 John Gilmore (gnu@cygnus.com)
2101 * stack.c (frame_info): If FRAME_FIND_SAVED_REGS isn't defined,
2102 print a newline to end the display anyway.
2104 * sparc-tdep.c (sparc_pop_frame): Pop the fsr and csr (float and
2105 coprocessor status regs) when popping a frame. This fixes
2106 float exceptions that occur after calling inferior functions.
2108 * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
2109 Read and write the fsr (float status register) to/from the child
2110 process along with the float regs. Remove Peter Schauer's change
2111 of May 24 '93, which has higher overhead and doesn't solve the
2112 real problem (which was that FSR wasn't being set).
2114 Mon Jan 10 23:16:42 1994 John Gilmore (gnu@cygnus.com)
2116 * a29k-tdep.c (examine_prologue): Don't worry if the ASGEQ
2117 stack overflow check isn't right after the register stack
2118 adjustment instruction. Metaware R2.3u compiler moves other
2119 things in front of it. This fix isn't perfect but is what's
2122 Mon Jan 10 20:08:23 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2124 * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
2126 * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
2127 character filenames.
2128 * configure.in: Change accordingly.
2130 Mon Jan 10 15:48:36 1994 Tom Lord (lord@rtl.cygnus.com)
2132 * m68k-stub.c, sparc-stub.c: removed spurious introduction of
2133 _filtered io routines from these two files.
2135 Fri Jan 7 12:42:45 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2137 * config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
2138 config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET): Define.
2139 * mdebugread.c (parse_symbol): Handle enum sh.type produced by
2141 * mdebugread.c (add_line): Handle zero linenos produced by DEC c89.
2143 Fri Jan 7 12:55:25 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2145 * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
2146 printing to gdb_stderr.
2148 * remote-udi.c (udi_kill): Don't close the connection, just set
2149 inferior_pid to zero.
2150 (udi_mourn): Call remove_breakpoints.
2152 * remote-udi.c: Remove obsolete need_artificial_traps comment.
2154 * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
2156 Thu Jan 6 07:17:53 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2158 * symtab.c (lookup_symbol): Don't try adding .c to the name.
2160 * remote-bug.c: At the start of each section, reset srec_frame
2163 * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
2164 * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
2165 * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
2166 code which looks for those two waitkinds. Use switch statement.
2167 * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
2168 CHILD_SPECIAL_WAITSTATUS.
2170 * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
2171 * Move target_signal_from_host, target_signal_to_host, and
2172 store_waitstatus from inftarg.c to target.c. procfs needs them.
2173 * target.c: Include "wait.h" and <signal.h>.
2174 * target.h, infrun.c (proceed), proceed callers: Pass new code
2175 TARGET_SIGNAL_DEFAULT instead of -1. This avoids problems with
2176 enums being treated as unsigned and is cleaner.
2177 * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
2179 * infcmd.c (signal_command), infrun.c (signals_info):
2180 Don't allow user to specify numeric equivalent of
2181 TARGET_SIGNAL_DEFAULT.
2183 Tue Jan 4 15:34:36 1994 Stu Grossman (grossman@cygnus.com)
2185 * config/alpha/alpha-netware.mt: New target support for Alpha
2187 * configure.in: Add alpha-*-netware* target.

2191 * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
2193 Tue Jan 4 09:47:14 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2195 * target.h: Add enum target_waitkind, enum target_signal, and
2196 struct target_waitstatus. Change status argument to target_wait to
2197 be struct target_waitstatus * instead of int *.
2198 * target.h, infrun.c, all targets: Change type of signal arguments
2199 to resume(), proceed(), and target_resume() from int to enum
2201 * All targets (*_wait, *_resume): Change accordingly.
2202 * infcmd.c (program_info, signal_command), throughout infrun.c,
2203 * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
2204 * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
2205 signal code stuff right with the new signals would be non-trivial).
2206 * inferior.h (stop_signal): Make it enum target_signal not int.
2207 * target.c, target.h (target_signal_to_string, target_signal_to_name,
2208 target_signal_from_name): New functions.
2209 * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
2210 store_waitstatus): New functions.
2211 * procfs.c (procfs_notice_signals): Use them.
2212 * i960-tdep.c (i960_fault_to_signal): New function, to replace
2214 * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
2216 * objfiles.c (build_objfile_section_table): Don't abort() if
2217 objfile->sections is already set.
2219 * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
2220 to match recent change to exec.c.
2224 * main.c (print_gdb_version): Change year to 1994.
2226 * ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
2227 * Makefile.in (NONSRC): Add ChangeLog-93.
2229 Mon Jan 3 11:57:29 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2231 * stabsread.c (read_type): Allow defining several type numbers
2232 at once (e.g. "(1,2)=(3,4)="...).
2234 * stabsread.c (read_enum_type): Use TARGET_INT_BIT not sizeof (int).
2236 * breakpoint.c (frame_in_dummy): Check PC as well as frame.
2238 Mon Jan 3 02:47:03 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2240 * mdebugread.c (psymtab_to_symtab_1): Only pass N_STAB symbols
2241 to process_one_symbol.
2242 * symtab.c (find_pc_psymbol): Search global_psymbols as well to
2243 avoid caching a bad endaddr in find_pc_partial_function.
2245 Sun Jan 2 21:41:17 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2247 * config/m68k/tm-sun3.h: Don't define BELIEVE_PCC_PROMOTION.
2249 Sat Jan 1 04:35:23 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2251 * infrun.c (wait_for_inferior): Do not step or step resume past
2252 the end of a one-line function we just stepped into.
2254 For older changes see ChangeLog-93
2260 version-control: never
