10 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
11 stuff for config manual) here where it counts; updated
12 to use new subdir structure (gdb/doc/).
14 * Makefile: generated from above via
18 * gdbint.texinfo: added instructions on generating gdb.info* files
19 locally for release. These are ordinary info
20 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
21 Makefile)---but due to use of texinfo 2, can't count on makeinfo
22 to generate these, so we distribute them already formatted.
24 * gdb.texinfo: included full Info node and menu crud (as generated
25 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
27 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
28 put in comments-for-future gdb.info target (one day makeinfo will

75 to make it easier to interface to "configure"'d libraries.
77 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
79 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as

494 infrun.c (start_remote): Also call wait_for_inferior & normal_stop.
496 Sat Apr 13 22:11:42 1991 Jim Kingdon (kingdon at spiff.cygnus.com)
498 * exec.c: Include <ctype.h>.
500 * sun3-xdep.c (fetch_core_registers): Add #ifdef FP0_REGNUM.
502 Fri Apr 19 09:36:50 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

505 tm-sun3.h: Define TARGET_SUN3.
507 * utils.c: Use CPLUS_MARKER not '$'.
509 * cplus-dem.c: Use CPLUS_MARKER not '$'. If CPLUS_MARKER isn't
510 defined, define it to '$'.
512 * arm-opcode.h: New file (same contents as before; it had
513 just been left out of the distribution for a long time).
515 * tm-68k.h: Put declaration of ext_format_68881 outside the macros.
517 * main.c: New HAVE_SIGSETMASK #ifdefs.
519 * coffread.c (read_coff_symtab): Check for "LF%" with all the
522 * coffread.c (SDB_TYPE): New macro.
523 various: Use it instead of checking against T_NULL.
525 * Makefile.dist (cplus-dem.o): Hack in an #include "param.h"
526 before we compile it.
527 defs.h: Protect against multiple inclusion.
528 param.h: Include defs.h.
529 signame.c: Change #ifdef SYS_SIGLIST_MISSING to #if.

541 * mips-xdep.c (fetch_core_registers): #if 0 out the whole function.
543 * Move read_memory_nobpt from mem-break.c to breakpoint.c.
545 Mon Apr 15 21:45:35 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
547 * utils.c (_initialize_utils): Rename "set demangle" to
548 "set print demangle", "set asm-demangle" to "set print

576 (_initialize_main): Rename "info version" to "show version".
578 * values.c: Rename value_history_info to show_values.
579 (_initialize_values): Rename "info values" to "show values".
581 Sun Apr 14 23:08:34 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
583 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
584 New function to give correct error message.
586 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
588 * target.h: Add to_doc and target_preopen.
589 target.c: Add target_preopen and target_command.
591 (add_target): Call add_cmd and mess with targetlist->doc.
592 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
593 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.

611 Rename add-syms to add-symbol-file.
613 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
615 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
616 * symfile.c (clear_symtab_users_once, cashier_psymtab,
617 free_named_symtabs): Move these routines from symmisc.c.
618 * symmisc.c (same): same.
619 (free_symtab): Make non-static.
620 * symtab.h (free_symtab): Declare as exported void fn now.
621 * dbxread.c (end_symtab, end_psymtab): Change comments.
622 (initialize_dbxread): Call dbx_new_init() in case the first
623 command is add-symbols.
624 * target.c (dummy_target): Permit add_syms_addr_command.
626 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
628 Permit symbols to be superseded when new symbol files have
629 been read in, particularly for VxWorks.
631 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
632 to the main file, as well as to include files. Also, put global
633 functions into the global psymtab, to make "i fun" work.
634 (end_psymtab): Free named symtabs and psymtabs for a file, once a
635 new psymtab for it has been read.
636 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
637 a file, once a new symtab has been read for it.
638 * mipsread.c: FIXME. We need to do the same for MIPS, but it
639 looks harder to determine the top-level block before it's been
640 queued to the psymtab list.
642 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
643 If we have wiped out any old symbol tables, clean up at end of
645 (symbol_file_command): Don't reference symfile_fns if it's zero.
647 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
648 defines for the blocks of a blockvector that contain global and
649 file-static symbols and the first of the smaller scope contours.
650 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
651 decode_line_1, make_symbol_completion_list): Use the above.
652 * coffread.c (end_symtab, patch_opaque_types): Ditto.
653 * dbxread.c (end_symtab): Ditto.
654 * expread.y (block): Ditto.
655 * mipsread.c (throughout): Ditto.
656 * symmisc.c (free_named_symtabs): Ditto.
658 * symtab.c (list_symbols): Process the first symbol of the
659 static psymbols list.
660 (types_info): Restore this function from its untimely #if 0.
661 It's not perfect, but it is better than nothing.
662 (_initialize_symtab): Restore "info types".
664 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
666 * m68k-stub.c: Remote stub for 680x0's, created from
667 rem-m68k.shar (which is removed).
668 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
669 Remove RCS log stuff now that we use CVS and it blows our diffs.
671 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
673 * symmisc.c (free_named_symtab): Make it work, in its current
674 kludgy fashion. Change result to indicate if we blew away bkpts.
675 * dbxread.c (end_symtab): Accumulate result from
676 free_named_symtab and print warning if we blew user's state.
677 * symfile.h: free_named_symtab now returns an int.
679 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
681 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
682 is the first symbol read, even if not mainline.
683 (dbx_psymtab_to_symtab): symfile might be zero, cope.
684 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
685 (set_section_command): New command ("section xxx yyy" -- should
686 be renamed to "set section xxx yyy" FIXME) which sets the
687 base address of a section of the exec file, overriding the
688 virtual address that BFD reports.
690 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
692 * exec.c: Add add_syms_addr_command to exec_ops, so you can
693 load symbols at any address while examining an exec file.
695 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
697 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
698 for printing the float info is host-dependent, not
699 target-dependent. FIXME.
700 * i386-pinsn.c: Move #includes to top, remove useless ones.
701 * i386-tdep.c: Don't bother including <.../reg.h> since we
702 don't use it (and it doesn't exist on host systems).
704 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
705 Convert negative numbers properly.
706 (ieee_test): Make numbers really random; fix format arg.
708 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
709 * core.c (core_detach): Unpush core_ops, which might not be on
710 top. We used to just pop the top, which broke things. Don't
711 need dont_repeat() any more.
712 (core_file_command): Psst! Don't repeat it.
713 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
714 * expprint.c (print_subexp): Avoid switch fallthru on
715 BINOP_ASSIGN_MODIFY, so we can print += and such.
717 * inflow.c (kill_command): After killing inferior, print our
718 current frame in the core file, if we have one.
719 (generic_mourn_inferior): When inferior dies, either select
720 the current frame (in the new target, e.g. core file), or
721 set both the current and selected frames to NULL.
723 Changes from Peter Schauer.
725 * infptrace.c: Avoid <sys/ptrace.h> on USG.
727 * Make all file names fit in 14 characters (sigh and damn!):
728 mv hp300hpux-xdep.c hp300ux-xdep.c
729 mv symmetry-xdep.c symm-xdep.c
730 mv symmetry-tdep.c symm-tdep.c
731 mv convex-opcode.h convx-opcode.h
732 mv tm-vxworks960.h tm-vx960.h
733 mv tm-vxworks68.h tm-vx68.h
734 mv Makefile.srcdir Makefile.sdir
735 mv gdb-int.texinfo gdbint.texinfo
736 mv remote-sa.m68k.shar rem-m68k.shar
737 mv remote-multi.shar rem-multi.shar
738 * Makefile.dist, README, config.gdb, convex-pinsn.c,
739 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
740 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
743 * command.c (user_info_1, user_info): New command for listing
744 the user-defined commands.
746 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
748 * dbxread.c (really_free_pendings): Clear file_symbols
749 and global_symbols after freeing them; otherwise, running
750 this function twice (if it appears twice on the cleanup
751 chain), we try to free things twice.
753 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
754 based on text_addr (the address of text in core), not on addr (the
755 offset between text in the .o file and in core). This change
756 is from Peter Schauer.
758 * main.c: Define ALL_CLEANUPS as a cast of zero.
759 (return_to_top_level): Use it.
760 (main): Do all cleanups after each command run as part
761 of the gdb startup sequence. Also do all cleanups before
762 entering the command loop, and every time we exit the command
763 loop and reenter. Before, the cleanups from the startup sequence
764 were being left undone until the first error!
765 (command_loop): Rename do_nothing cleanup to command_loop_marker
766 so we can see it easily when examining the cleanup chain.
767 (init_signals): Add another do_nothing for signal handling.
768 (quit_command): Only try to kill target if it has execution.
769 Problems in the target stack got us into a state where
770 inferior_pid was nonzero but none of the targets had execution.
771 In this state you couldn't exit gdb.
773 * dbxread.c: Two changes from Peter Schauer.
774 (echo_command): Fflush output after an echo command.
775 (show_history): Pass all args to cmd_show_list.
777 * utils.c (init_malloc): Call mtrace to turn on tracing
778 if the environment variable MALLOC_TRACE is set to a file name.
779 * mtrace.c: Add source file which provides a log of every malloc,
780 free, and realloc to a trace file.
781 * mtrace.awk: Add source file which analyzes the trace file.
782 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
783 (VERSION): Roll to 3.94.3.
785 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
786 (check_duplicates): Don't bother with watchpoints.
787 (set_raw_breakpoint): Comment about danger of this routine.
788 (watch_command): Parse and eval all args before calling
791 * solib.c (find_solib): Avoid error in referencing memory to
792 see if any more shared libraries have been added. This is
793 particularly useful if the target has terminated. Bug reported
797 in bringing up 3.94.2 on the Sun-3.
799 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
800 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
801 expression (in scope) before reenabling watchpoint.
802 * signame.c (init_sigs): Add missing declaration of i, fix
803 sys_siglist declaration.
804 * source.c (list_command): Fixed range computation to use
806 * stack.c (backtrace_command): Do not allow command if target has
807 no stack, print informative error message.
808 * target.c (target_command): Do not write into command line
809 because this fails if the target command is used in a user defined
810 command. [This change was enhanced by gnu to support any-
811 unique-prefix matching on target names.]
812 * valops.c (value_struct_elt): Avoid infinite loop on an
813 erroneous attempt to print the member of function (try p main.p).
815 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
817 * expread.y (name_no_typename): Avoid reduce/reduce errors
818 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
819 Since the GDB parser really doesn't use name_no_typename in a
820 name-only context, the parser can't tell the diff between
821 names and numbers here. Avoid allowing a name_no_typename
822 to be a NAME_OR_*INT to resolve the conflict.
824 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
828 * valprint.c (val_print_fields): bitfield printing didn't handle
829 byte order. Indirect through a few more fns to cope.
831 * values.c (modify_field): also cope with byte order.
833 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
835 Cleanup for release 3.94.2:
837 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
838 include files. Roll version to 3.94.2.
840 * coffread.c (init_stringtab): Read length into unsigned char
841 array before swapping; don't assume 32-bit longs.
843 * target.c (target_info): Don't bother with get_sym_file, just use
844 the symfile global variable.
845 * symtab.h, symfile.c (get_sym_file): Delete it.
847 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
848 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
849 (read_type): Replace one more error() with complain().
851 * mipsread.c (parse_partial_symbols): Replace printf with complain.
853 * i960-tdep.c: Fix copyright attribution.
855 * config.gdb: Quote all backquotes in doublequotes. You can
856 quote me on that. BSD 4.4 shell found this one.
858 * infptrace.c (throughout): The third argument to ptrace is an
861 * infrun.c (wait_for_inferior): When program has terminated, we
862 have to call target_terminal_ours before we pop that target off
863 the stack (e.g. before a call to target_kill or
864 target_mourn_inferior). This fixes problem where a program
865 terminates, then GDB stops for (tty output) and you have to type
866 "fg" to the shell to resume it. FIXME: This code for what to
867 do after termination really should be in normal_stop instead.
869 * gdbcore.h (read_memory_check): Change declaration; it changed
872 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
873 4.4 prereleases, this avoids a bug in their sgtty compatability
875 * remote.c: Use terminal.h rather than hand-rolling the same.
877 * signame.c, signame.h (psignal): Arg is unsigned, not int.
878 * utils.c (strsave, strstr): Fix arg types.
879 * valprint.c (val_print): lint
881 MIPS symbol table support from Per Bothner:
883 * symfile.c (symtab_fns): Remove initializer table that needs to
884 be hacked for each new symbol file format supported.
885 (add_symtab_fns): New function, chains symbol table
886 handlers into the global list.
887 (symfile_init): Search this list.
888 * symfile.h: Add next pointer, declare add_symtab_fns.
889 * coffread.c (_initialize_coffread): Call add_symtab_fns.
890 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
892 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
893 symbol *). Thus, we no longer need the hack to trash
894 pst->filename. Good, since that hack confused code in symfile.c!
896 (reorder_symtabs, destroy_all_symtabs): Removed static
897 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
898 Instead, the latter now uses a temporary array (stack-allocated
899 from an obstack, and then freed).
901 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
902 haven't been set in the outermost stBlock of a procedure. This was
903 a problem with f77 binaries on Ultrix 4.?.
905 (new_symtab, new_symbol, new_type): Continue changing code to use
906 obstacks more and otherwise conform to dbxread internal style.
907 Made the free_code of symtabs be free_linetable (as in dbxread)
908 instead of free_contents. This implies memory leaks when reading
909 a new symbol table, until the conversion is finished. Did change
910 (struct symbol) and (struct type) to be allocated on the
911 symbol_obstack. Blocks and blockvectors are among the things
914 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
915 tested much, but it solved one problem (reported by Meissner), and
916 cleans up some other things. The problem happened when an
917 included file contains actual code (functions) and not just
918 definitions. The mips coff is a little inconvenient there, since
919 it may cause a procedure to be mapped to the wrong psymtab.
921 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
922 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
923 this will need work for the new core paradigm.
925 Opcode patches from the net:
927 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
928 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
929 missing altogether - they are added here. From Bruce Bauman.
930 * mips-opcode.h: The low mask for C0 instructions was too small.
931 From Garrett Lau. I modified the fix to check the entire 32-bit
934 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
937 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
939 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
941 * dbxread.c (read_type): Pointer subtraction (value_sub in
942 valarith.c) sometimes failed because the types of the
943 pointers being subtracted were not identical.
944 These differed because dbxread.c was allocating pointer types
945 using dbx_alloc_type+smash_to_pointer_type instead of
946 lookup_pointer_type. I failed to find a justification for the
947 former, so I changed it to use the latter. Similarly, I
948 replaced smash_to_function_type by lookup_function_type,
949 and smash_to_reference_type by lookup_reference_type.
951 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
952 _initialize_mipsread): corresponding changes.
954 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
956 * source.c (mod_path): Do tilde_expand on each component of the path,
957 rather than on the (list of) paths as a whole.
958 (print_source_lines): Set first_line_listed in addition to
959 current_source_symtab and current_source_line. If the source was
960 not findable, after a "dir" command to fix the problem,
961 a "list" would get the wrong lines.
963 While I was there... (gnu):
965 * dbxread.c (read_type): Change error to complaint.
967 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
969 First attempt at detailed understanding of symbol table memory alloc.
971 * dbxread.c (dbx_symfile_read): Free our string table if we
972 aren't the mainline. Free the "info" struct since we're done with
974 (init_psymbol_list): Free any previously allocated psymbol lists.
975 (): FIXME: Should realloc-down the psymbol lists when done reading
976 the main symbol file?
978 * symmisc.c (free_symtab): Free fullname field too.
980 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
981 (REGISTER_ADDR): Make result type unsigned int.
983 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
984 define REGEX must also define REGEX1 (its dependency).
986 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
988 * tconfig/i960: No longer works, points you at vxworks960 or
991 * xgdb.c, XGDB-README: Remove file. Users can get the much
993 * Makefile.dist: Remove all trace of xgdb.
995 * breakpoint.c (breakpoint_1): Pass demangle arg to
996 print_address_symbolic.
997 (clear_breakpoints): Remove unused function.
998 (breakpoint_re_set_one): Guts of breakpoint_re_set.
999 (breakpoint_re_set): Use catch_errors to do them all anyway.
1001 * gdb-int.texinfo (Host versus Target): Add section on what is
1002 a "host" feature versus what is a "target" feature.
1004 * infcmd.c (path_command, path_info): Handle the PATH variable
1005 (object search path) as conveniently as the source search path.
1006 * environ.c (set_in_environ): Set some vars in GDB's environment,
1007 in addition to the child's. PATH, G960BASE, G960BIN for starters.

1020 * infcmd.c (do_registers_info): Print floating point registers
1021 in raw hex as well as float format, regardless of whether it is
1022 a "virtual" convertible register.
1023 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1024 regs as a double, just in case it's being used that way.
1025 * values.c (unpack_long): Comment on array/function coercion.
1026 (unpack_double): Argument is in target byte order now. For
1027 integer arguments, just call unpack_long and float the result.
1028 * m68k-tdep.c: include defs.h for "const" handling.
1029 * remote-nindy.c: Use ieee-float stuff.
1030 (nindy_fetch_registers): Unpack double regs to host double, then
1032 (nindy_store_registers): Pack extendeds to host double, flip
1033 around by misusing unpack_double, send as target double.

1044 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1046 * coredep.c (fetch_core_registers): Pass end-address of register
1047 section to register_addr as expected. Don't call supply_register
1048 if we'd just pass it garbage.
1050 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1052 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.

1097 * inftarg.c (child_detach): Pop the child_ops vector if the
1098 detach is successful.
1099 * remote-nindy.c (nindy_create_inferior): Don't push a new
1100 nindy_ops since nindy uses the same one for execution and memory
1102 * core.c (core_ops): Use child_attach and child_create_inferior
1103 rather than default attach and create_inferior functions.
1105 Handle floating point registers in core files.
1107 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1108 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1109 This version untested since BFD doesn't yet support sun3 core
1111 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1112 conventions. Fix comments and style. This version has not
1113 been compiled yet, since we have no HP inhouse.
1114 * core.c (get_core_registers): Look for two sections, ".reg"
1115 and ".reg2", and pass both to fetch_core_registers sequentially.
1117 Revise directory path yet again.
1119 * source.c (forget_cached_source_info): Not static any more.
1120 (init_source_path): New default source path is "$cdir:$cwd".
1121 (dir_command): Handle variable arguments ($cdir, $cwd).
1122 (source_info): Print "Compilation directory" rather than
1123 "Originally compiled in" to remind people of $cdir.
1124 (openp): If the path contains $cwd, use current directory.
1125 (open_source_file): If compilation directory is known, replace
1126 first $cdir in path with the compilation directory.
1127 (print_source_lines): Even if we can't print the lines, set the
1128 current symtab and line for future commands like "info source" or
1129 "breakpoint". Also, error message now contains the file name,
1130 line number, and file access error message.
1131 (_initialize_source): Fix help text to describe changes.
1132 * main.c (cd_command): Forget cached source info when we chdir.

1138 Byte-swap COFF symbol tables if necessary when reading them in.
1139 Use complain() to replace error message in one spot. Needs
1140 corresponding change in bfd/coff-code.h to make some symbol
1141 swapping routines non-static.
1143 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)

1153 declarations of errno.
1155 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1157 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1158 <rpc/rpc.h> and <rpc/types.h>.
1160 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1162 * i960-tdep.c (examine_prologue): Add new argument limit,
1163 which stops the scan at the end of the prologue, or at the PC.
1164 This fixes a problem where it walks down into the code for the
1165 user's statements if that code looks like function prologues.
1166 Mark Fox and I have been bouncing this code back and forth, making
1167 small changes to it. Callers changed to match.
1169 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1171 Cleanup for gdb-3.94 release final:
1173 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1174 the .c files from vx-share and nindy-share, from the various
1175 macros, since they are not found via ALLDEPFILES.
1176 (SFILES): Add tm-i960.h.
1177 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1178 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1180 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1181 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

1185 * am29k-tdep.c: Add contribution line.
1186 (examine_prologue): Cache information about function prologues in
1187 the misc-function-vector to avoid lots of references over the
1188 serial line while examining instructions.
1190 * core.c (core_close): New function made from cleanup_core.
1192 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1193 remote-vx.c, remote.c, target.c, target.h,
1194 Update target_ops vector to add attach, close, and load entries.
1195 Use add_syms_addr_command, not add_file_addr_command, for
1196 add_file. Break out close routine from existing code.
1198 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1199 they are in an obstack.
1200 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1202 (define_symbol): Add symbol type parameter; change callers;
1203 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1204 it to influence the symbol class on the i960.
1205 (define_symbol): Swap LOC_CONST's into target byte order.
1207 * exec.c (exec_close): New function.
1208 (exec_file_command): Call it.
1210 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1211 Fix byte order of frame pointer.
1212 (read_var_value): Result of 0 if var's value can't be found,
1213 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1214 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1215 (locate_var_value): Use read_var_value and use its lazy address
1216 as the location of the var's value. Lint.
1218 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1221 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1222 obsolete Intel versions in favor of vxgdb versions.
1223 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1224 code dealing with byte order of values, which Intel did in host byte
1225 order rather than gdb-4's target byte order.
1226 (i960_frame_chain_valid): Move to nindy-tdep.c.
1227 (examine_prologue, skip_prologue, frame_find_saved_regs,
1228 frame_args_address, leafproc_return, saved_pc_after_call,
1229 pop_frame): Add vxgdb versions from Mark Fox.
1230 (examine_prologue, frame_struct_result_address): Add code
1231 to deal with the saved value of G13 (struct return address
1233 (frame_args_address): Modify Mark's version to prefer the
1234 saved value over the current value in the topmost frame.
1235 Cache result in the frame info to avoid performance hair in
1237 (print_fault): Add gdb960 code for printing faults.
1238 (_initialize_i960): Actually call check_host.
1240 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1241 add stub routines. FIXME, these currently just return zero!
1243 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1244 (attach_command): Call target_attach, not target_open, now.
1246 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1247 (child_attach): Rename from child_open.
1248 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1249 don't confuse it with a zero step_resume_break_address.
1251 * inftarg.c (child_detach): Eliminate inferior_pid test.
1252 (child_files_info): Clean up message a bit.
1253 (child_ops): Use child_attach, not child_open, to attach.
1255 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1256 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1257 findvar.c to here, since it depends on the contents of the
1258 shadow_contents of breakpoints, but keep if #if 0 since it is
1261 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1264 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1265 (ptype_command, display_command): Eliminate have_inferior_p and
1266 have_core_file_p in favor of target_has_stack or
1267 target_has_execution.
1268 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1269 code for actually finding the values of arguments, though we still
1270 keep track of the maximum stack offset for use in printing unnamed
1271 arguments. Handle missing FRAME_ARGS_ADDRESS.
1273 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1274 (struct nindy_regs): Define registers passed to/from nindy.
1275 (nindy_fetch_registers, nindy_store-registers): Translate between
1276 nindy and GDB formats for the registers.
1277 (dcache_init): Statically allocate the cache, since it was being
1278 allocated by a malloc that was never freed anyway.
1279 (nindy_create_inferior): Error, not core dump, if no exec file.
1280 (nindy_before_main_loop): Use target_load, not target_add_file.
1282 * remote-vx.c (net_load): Specify large timeout for load
1283 requests. Allow user to break out with INTERRUPT.
1284 (net_break): Remove useless code, clean up. Change callers.
1285 (parse-args, skip_white_space, find_white_space): Clean up arg
1286 parsing to cope with quoted strings.
1287 (net_wait, net_quit): Never call error, just return status.
1288 (vx_read_register, vx_write_register): Cleanup status checking.
1289 #ifdef the code based on which CPU we are using (960 or 68k),
1290 FIXME, this should be completely general but it isn't yet.
1291 (vx_xfer_memory, vx_resume): Cleanup status checking.
1292 (vx_run_files_info): Improve message.
1293 (vx_load_command): Renamed from vx_add_file_command. Allow load
1295 (net_ptrace): Remove unused routine.
1296 (vx_wait): Adopt code from vxgdb960 to cope with broken
1297 connections to target machine and prompt to disconnect. Remove
1298 debug printouts. Map some EVENT_'s to SIGnals.
1299 (add_symbol_stub, vx_open): Print names of object files we found,
1300 and "ok" if we read their symbols OK. Clarify output in general.
1301 (vx_attach, vx_detach, vx_kill): Add these commands.
1302 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1303 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1304 "info files" output, and create_inferior, since we already have
1307 * stack.c (frame_info): Replace Frame_unknown with 0.
1308 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1309 (return_command): Pop until the PC matches as well as the FP,
1310 so it works even if the FP is shared with another function,
1311 as in "frameless" or "leaf" procedures.
1313 * symfile.c (load_command): renamed from add_file_target_command.
1314 (add_syms_addr_command): renamed from add_file_addr_command.
1315 (add_syms_command): Stub to call target_add_syms.
1316 (_initialize_symfile): Change command names and descriptions,
1317 add-file => add-syms, and load from alias to its own command.
1319 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1320 maybe_kill_then_create_inferior): Default for attempts to start
1321 a process, if one is already running, is to ask about killing
1322 it and retry if yes.
1323 (upstack_create_inferior): #if-0 it, strata obsolete it.
1324 (push_target, unpush_target, pop_target): to_close() a target
1325 before unstacking it.
1326 (target_info): Renamed from target_files_info.
1327 (_initialize_targets): Rename "i files" as "i target", accessible
1330 * target.h: Improve comments about the target_ vectored routines.
1332 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
1333 Convert commenting style to standard GNU style.

1335 (SKIP_PROLOGUE): No longer a no-op.
1336 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1337 (*_REGNUM): Sort register numbers.
1338 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1339 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1340 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1341 are now 10 byte extendeds, not 8 byte doubles.
1342 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1343 for nindy versus vxworks targets. FIXME, this should possibly go
1344 in the target vector.
1345 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1346 frame_saved_regs and arg pointer with each frame.
1347 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1348 (FRAME_ARGS_ADDRESS): Use cached result.
1349 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1350 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1351 (PRINT_RAMDON_SIGNAL): Call print_fault.
1352 (POP_FRAME): Now works.
1354 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1355 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1356 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1357 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1360 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1361 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1363 * valarith.c (value_subscripted_rvalue): Avoid handling
1364 floats and doubles specially; it gave alignment errors. Lint.
1366 * valops.c (value_of_variable, value_of_this): Error if unknown
1369 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1370 to avoid alignment problems.
1371 (value_print): Handle unknown value address.
1372 (cplus_val_print): Two args are ignored; remove them. Change caller.
1373 (val_print): Use unpack_long rather than pointer-deref.
1376 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1377 to avoid alignment problems.
1378 (value_being_returned): Error if return value unknown.
1379 (set_return_value): Add bogosity warning, FIXME. *
1381 * TODO: A woman's work is never done.
1383 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1384 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1385 Add ieee-float.o to OBS.
1386 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1387 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1388 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1390 Changes to generalize the VxWorks RPC protocol slightly, to handle
1391 i960 as well as 68000.
1393 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1394 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1395 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1396 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1397 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1398 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1399 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1400 so they will move in target byte order rather than network
1401 byte order (happens to be the same).
1403 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1405 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1407 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1410 Add contribution lines to various files, showing where they
1413 * breakpoint.c (break_insn, check_break_insn_size,
1414 read_memory_nobpt): Remove to mem-break.c.
1416 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1419 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1420 entry has bad register number. This change is not
1421 tested in this release, FIXME.
1423 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1426 * value.h: Force value's contents field to be aligned to hold
1427 at least a double or a long long (if supported). This avoids
1428 doing bcopy's in and out of the contents field.
1430 (step_1): Avoid coredump under obscure circumstances when we
1433 * symtab.h (misc_info): Add field to misc function vector for
1434 any kind of cached information the target code desires. AMD
1435 29000 uses this to avoid repeating examine_function_prologue's.
1437 * coffread.c: Lint. Remove static symfile, read_section_header.
1438 core.c (have_core_file_p): Lint: remove.
1439 expprint.c (print_subexp): Lint.
1440 infptrace.c, valops.c, valprint.c: lint.
1442 Roll in changes from vxgdb-5.0.1:
1444 * symtab.h: Comment byte order of each address class. Add
1445 LOC_LOCAL_ARG for frame-relative args (960).
1446 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1447 symtab.c, symmisc.c: ditto.
1449 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1451 * remote.c (remote_resume): Error if resume with a signal.
1453 * symfile.c (prim_record_misc_function): Clear misc_info.
1454 (fill_in_vptr_fieldno): Check stub type of arg.
1456 * valops.c (value_cast): Avoid looking up names of types whose
1457 name we don't know, to prevent coredump. Sun CC produces typedef
1458 rtx and the name of *rtx is zero...
1460 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1462 Roll in changes from final AMD 29000 port (Tiemann).
1464 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
1465 for ../include/a.out.encap.h. This might not work now that BFD
1466 is separately compiled. Instead, BFD support for encap will have
1467 to translate machine type 29k into the right COFF_MAGIC.
1469 * infcmd.c: Remove references to inferior_pid that aren't used
1470 in actual ptrace calls; use target_has_execution, etc.
1471 (have_inferior_p): Remove function.
1472 (program_info): Print target info rather than "process number";
1473 avoid gratuitous messages unless from_tty.
1474 (run_stack_dummy, finish_command): Set proceed_to_finish.
1475 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
1476 main.c: Lint. Lose have_inferior_p().
1477 inferior.h (have_inferior_p): Remove, lint.
1478 (proceed_to_finish): Add flag to ask that all regs be saved
1479 by normal_stop, for the few commands that need it, speeding up
1480 serial I/O. Add comments to stop_registers.
1482 * remote-eb.c: Remove newline from breakpoint message we grep
1483 for. Never time out when running the user program.
1487 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1489 Roll in changes from vxgdb-5.0.1:
1491 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
1492 symbol in its raw form, we are processing an unlinked ".o" file.
1493 See if the target environment has assigned it an address, using
1494 target_lookup_symbol (VxWorks does), and enter it into the symtab
1497 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
1498 68k versions for a simpler version that assumes zero FP at bottom.
1499 Fixes bug of truncated stack reports.
1501 * target.h (target_lookup_symbol): Define this routine's args
1502 and result, finally.
1504 * target.c (nosymbol): Default routine for target_lookup_symbol.
1505 (target_default): Default lookup_symbol and call_function too.
1506 (files_info): Only print has_all_memory warning if a non-dummy
1509 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
1510 vx_convert_from_virtual): If target does not have floating point,
1511 zero register "values", and avoid doing cross-net conversions.
1512 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
1513 (vx_open): Rearrange code that attaches to target and reads
1514 symbols for all loaded modules, to work if some of the modules
1515 are not accessible. Add symbol_stub() and add_symbol_stub()
1516 as callbacks from catch_errors(). Allow connect attempt to be
1517 interrupted painlessly with ^C (FIXME, there are still some bugs
1518 if the interrupt happens during symbol reading.). Print
1519 final message with puts_filtered, since symbol messages are
1524 * main.c (catch_errors): Only print errstring if non-null.
1525 (command_loop): Avoid an ioctl per command to test ISATTY.
1527 * remote-vx.c (net_load): make static; avoid sophomoric msg.
1528 (vx_xfer_memory): Return correct result!
1529 (vx_files_info): Indicate whether target has float or not.
1530 (vx_lookup_symbol): Complain, not error, if target gone.
1531 (vx_open): Print "Connected" msg before disabling immediate-quit.
1532 [FIXME: lookup_symbol and vx_open changes need testing.]
1534 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
1535 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
1536 contributor lines and update copyrights to 1991.
1538 Changes from an attempted H-PUX host port:
1540 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
1541 defines PT_ATTACH and PT_DETACH but not PT_KILL.
1542 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
1543 * remote-vx.c: include <sys/time.h> for HPUX.
1544 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
1545 "core_file_command" routine to BFD regime. May not work yet.
1547 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
1549 * xgdb.c: Replace X10 version with some VJ version.
1550 (FIXME: Its copyright assignment is not on record.)
1551 * xgdb.c: Update include files to X11R4 (Xaw crud).
1552 (xgdb_display_source, create_text_widget): fix call to
1553 get_filename_and_charpos. Rewack source window stuff for X11R4
1554 (gleaned from include files, and "nm's" of binary libraries, since
1555 I had no doc available).
1556 (append_selection, append_selection_word): Disable with FIXME
1557 since R4 changed interface here.
1558 (create_buttons): Add back the old set of buttons.
1559 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
1561 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
1562 Roll VERSION to 3.94 (not yet final though).
1564 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1566 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
1567 obstack_int_grow, obstack_int_grow_fast): Eliminate
1568 cast on left of assignment, which gives MIPS cc fits and is
1571 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
1572 F_ALIAS. Use printf, not fprintf, when not passing a file
1574 (compare_opcodes): Check that identical instructions have
1575 identical opcodes, complain otherwise.
1577 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
1578 was reported by Roland McGrath.
1579 (unimp): Only match if exactly zero instruction. (Roland)
1580 (branches and traps): Generate all variations of these
1581 instructions with macros, based on a single call that defines
1582 each condition name and its binary representation.
1583 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
1585 * valprint.c (val_print_fields): Take, and use, format parameter.
1586 This means that "p/x struct" again prints the elements in the
1587 desired format. Changed callers.
1589 * stack.c (frame_info): Use filtered output, and indicate wrap
1590 points. Remove kludgy formatting designed to avoid line wrap.
1592 * utils.c (wrap_here): If the line is already full (because
1593 we had printed a long indent or long wrapped string), do an
1594 immediate newline-and-indent.
1596 * m68k-pinsn.c (print_insn_arg): Bugfix from
1598 instruction is incorrectly disassembled as bkpt #8.
1600 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
1602 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
1603 and then will dump core (sometimes). I traced it back to an
1604 uninitialized symfile_name in psymtab_to_symtab.
1605 (const_vol_complaint): Add quotes to message.
1606 (define_symbol): Only believe line number if gcc_compiled.
1607 Avoid allocating symbol if we will not return it.
1609 Add target strata support so that newly established targets go
1610 into their right place in the target stack (e.g. a new exec file
1611 doesn't wipe out the ability to access the running process).
1613 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
1614 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
1615 and initialize it properly in all the targets.
1617 * target.h: Document strata. Change return type of push_target.
1619 * target.c (nomemory): new function for dummy memory access.
1620 (tcomplain): Rename complain, now also used in symfile.c.
1621 (push_target): Push targets within strata. New return value shows
1622 whether new target is on top of stack or not. Always keep dummy
1624 (target_files_info): Ignore dummy target.
1626 * core.c (core_open): Warn user, and skip accessing file, if the
1627 core target is not the topmost target in the stack.
1628 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
1631 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
1632 target_ops, it doesn't belong there since we have no regs there.
1633 Change name of target from machine => memory to clarify.
1635 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
1637 * Freeze version 3.93 for release.
1639 * Makefile.dist: Handle vx-share and nindy-share subdirs
1640 properly when building gdb.tar.Z.
1642 * symtab.c: lint; add no_symtab_msg to consolidate the messages
1643 printed in various places, so I could change just one copy.
1645 * dbxread.c, coffread.c: Change references to bfd->iostream
1646 to cast to FILE *, now that BFD avoids needing types defined
1647 in other header files.
1649 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1651 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
1652 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
1653 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
1654 (actually gcc -Wall).
1656 * dbxread.c: Remove first_global_sym, last_global_sym, since
1657 they are never referenced.
1659 * defs.h (baud_rate): Declare.
1660 main.c: Define it, and add the -b option to set it.
1662 * gdb-int.texinfo: Add text on how to define a new host or target
1663 architecture, prompted by Per Bothner's questions about MIPS
1666 * gdb.texinfo: Document "complaints". Change doc of -q since
1667 gdb no longer prints the copyright and blurb if you specify a file
1668 name to be debugged (just like Emacs). Add doc for Nindy-specific
1669 command line flags for specifying target serial port and such.
1670 Update copyright to 1991.
1672 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
1673 has taken over for us the job of ripping up executable files. The
1674 crud caused Per Bothner's port to not compile.
1676 * infrun.c (normal_stop): Avoid printing "Program exited
1677 normally" if we are in batch mode. This allows a GDB which
1678 executes a program on a target system, to behave like a Unix
1679 command (input from stdin, output to stdout, no extraneous
1682 * main.c (main): Allow additional machine-dependent command line
1683 options to be specified with the ADDITIONAL_OPTIONS,
1684 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
1685 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
1686 processing to occur just before the main loop with
1687 BEFORE_MAIN_LOOP_HOOK.
1688 (main): If a "core file" argument is specified, and it is not a
1689 core file, try it as a process ID to attach.
1690 (symbol_completion_function): Attempt to cope with
1691 "show screen-" TAB, not very successfully. This needs more work,
1693 (batch_file): New function, returns whether we are reading
1694 commands from an interactive tty on stdin, or from somewhere else.
1695 Called by normal_stop since it doesn't get from_tty passed down
1696 to it like many commands do.
1698 * remote-nindy.c: Handle command line options for nindy
1700 (nindy_before_main_loop): Prompt user for tty name if they
1701 don't specify it before getting to the interactive command loop.
1703 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
1704 and -r command line options. Also add hook before main loop
1705 to make it easy to specify a tty.
1707 * TODO: More things to do, one done.
1709 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
1711 * dbxread.c: Make complaint() calls pass pointer, not struct.
1712 Add complaints about badly formatted C++ type information
1713 (const/volatile indicator, and parse errors resulting in
1714 error_type). Fix C++ virtual member fn comment.
1715 (read_struct_type): Avoid bumping pointer if we got a parse
1716 error; this prevents our walking beyond the end of a string.
1717 Terminate loop on null char as well as semicolon.
1718 (process_one_symbol): Fix the LBRAC fix so that it uses the
1719 last previous SLINE, FUN, or SO record's PC address. C++ debug
1720 symbols did not have SLINE records in a useful order compared
1721 to the LBRAC records.
1722 (define_symbol): Handle "catch" records.
1724 * symtab.c (check_stub_type): Added new complain
1725 `stub_noname_complain' and added a consistency check to
1726 keep the debugger from crashing when finishing from an
1727 exception frame. A real fix will be needed later.
1729 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1731 * infcmd.c (attach_command): Make global.
1733 * Makefile.dist (REMOTE_OBS): Make these compile by default,
1734 but make them easy to comment out. Perhaps later they should
1735 be enabled by what CPU you configure for? FIXME.
1736 (VERSION): Roll to 3.93.
1737 (pinsn.o): Remove rule for obsolete file.
1738 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
1740 Run down a problem that manifested by printing the wrong function
1741 name in stack traces of read_ofile_symtab. Turned out that the
1742 problem was the SunOS 4.1.1 (and previous) C compiler outputs
1743 the LBRAC symbol with an address in the *data* segment, which
1744 blew our binary search through the blocks.
1746 * dbxread.c: Use the complain() facility consistently to bitch
1747 about problems in the symbol file we are reading.
1748 (finish_block): Add code to check the nesting of the blocks;
1749 complain and Procrust them to fit if wrong.
1750 (make_blockvector): Check the order of the blocks, complain
1751 [but don't cope] if wrong.
1752 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
1753 symbols to be sure their PC value is greater than the last SLINE
1754 (line number) symbol we've seen, complaining and adopting the
1755 SLINE PC value if wrong.
1757 * symfile.h (struct complaint, complaint_root, complain,
1758 clear_complaints): Add.
1759 * symfile.c (complain, complaint_root, clear_complaints): Add
1760 facility to deal with non-fatal complaints and to regularize their
1762 (symbol_file_add): Clear complaint counters to allow new complaints.
1763 (initialize_symfile): Add 'set complaints' and 'show complaints'.
1765 * dbxread.c (dbx_symfile_read): Remember the address and size
1766 of the string table for the main symbol file, so we won't read it
1768 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
1769 to avoid reading the string table yet again. Lint.
1770 (throughout): Improve filtered output, including word wrap.
1771 (read_range_type): Improve Bothner's fix to handle other types too.
1773 * utils.c: Improve line wrap implementation. Handle unlimited
1774 width by making chars_per_line unsigned.
1775 (puts_filtered): New, easy, function.
1777 * defs.h (puts_filtered): add.
1779 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
1780 call the identical sort_symtab_syms() in symfile.c instead.
1782 * expread.y: Suggest the `file' command rather than `symbol-file'.
1784 * command.h (enum var_types): Add zinteger for seroable
1786 * command.c (do_setshow_command): Handle var_zinteger. Restructure
1787 nested if's into a switch.
1789 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
1790 we did not stop because of a breakpoint (it must have been for
1791 some other reason, like a "stepi"), so don't print anything.
1793 * symtab.c: Include <sys/types.h> all the time. Now that BFD
1794 doesn't include <sys/types.h>, old SunOS's require it for
1799 A test port of gdb-3.92.6 to the Sony NEWS.
1802 Don't normally link in remote- or vx stuff.
1803 Some of it doesn't compile, and it wastes space for 99% of the users.
1804 Remove reference to no-longer-used HAVE_VPRINTF.
1805 Fixed BFD_DEP typo to BFD_DIR.
1807 Fix cast in arg to bfd_h_getlong.
1808 Make char *prefix be const.
1809 Fix how certain range types are mapped into builtin unsigned int types.
1811 Remove 2 #includes. They cause errors (on Sony, at least),
1812 and aren't needed (they wern't in earlier versions).
1814 print_address_symbolic should never demangle labels
1815 (since it prints *assembler-level* labels).
1817 [This was superseded by the change to printcmd below.]
1820 Add some "volatile" return types to avoid warnings.
1821 If MISSING_VPRINTF add vprintf function and not just macro
1822 (since vprintf is used in printcmd.c).
1824 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
1825 (The latter isn't grokked by some PCC-based compilers.)
1827 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
1829 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
1830 * nindy-share/coffstrip.c
1831 Added some forward declarations (otherwise, gcc complains
1832 about implicit extern redefined as static).
1834 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1836 Changes inspired by Per Bothner:
1837 * printcmd.c (print_address_symbolic): Take additional parameter
1838 specifying whether to demangle.
1839 (print_address): Pass in asm_demangle to control demangling.
1840 (print_address_demangle): New fn, takes explicit arg to control
1842 * utils.c: Add new vars demangle and asm_demangle, and let them
1844 (fputs_demangled): If !demangle, just print the argument.
1845 (fprint_symbol): If !demangle, just print raw symbol.
1846 * valprint.c (val_print): Call print_address_demangle rather than
1847 print_address, to cause demangling to depend on the global
1848 rather than assembler-level demangling setting.
1849 * WHATS.NEW, gdb.texinfo: Document.
1851 * main.c (show_command): Show all settings if no arg.
1852 (initialize_main): Make "info set" the same as naked "show".
1853 * command.c (cmd_show_list): Handle prefix commands in the
1854 list, and print the name of the setting as well as its English
1855 description and value.
1857 Allow gdb functions to specify where a line should wrap if it
1858 exceeds the size of a terminal line. Use it to make the output
1860 * utils.c (set_screen_width_command): New fn, mallocs a buffer
1861 of the right size when screen width changes.
1862 (set_screensize_command, screensize_info): Remove #if 0'd fns.
1863 (wrap_here): New fn, indicates a point in the output where we
1864 should wrap the line rather than just letting it overflow at a
1866 (fputs_filtered): Implement wrapping.
1867 (n_spaces): New fn, returns a pointer to N spaces.
1868 (print_spaces_filtered): Use n_spaces.
1869 * defs.h (n_spaces): Declare.
1870 * stack.c (print_frame_info): Wrap with 4-space indent after
1871 fn name and before filename and line number.
1872 * printcmd.c (print_frame_args): Wrap with 4-space indent
1873 before each argument name is printed.
1874 * valprint.c (value_print): Wrap with no indentation before
1876 (val_print_fields): Wrap with indentation relative to nesting
1877 level before each field name.
1878 (val_print): Wrap with nesting indentation before array elements.
1879 * command.c (do_setshow_command): Avoid extra newlines,
1880 wrap with 4-space indent around values printed, end with period.
1881 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
1883 * breakpoint.c (breakpoint_1): Implement addressprint for
1884 "info breakpoints" display. Change file name and line number
1885 format to " at file:nnn" rather than " (file line nnn)".
1886 * gdb.texinfo: Document.
1889 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1891 Frozen for gdb-3.92.6 release.
1893 README, WHATS.NEW: Update for 3.92.6 release.
1895 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
1896 coffread.o from configs since it is now built by default.
1897 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
1898 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
1899 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
1900 from configs since it is now built by default.
1902 Makefile.dist: Update for release 3.92.6. Handle files that
1903 have been moved to ../include, ../getopt, or ../bfd. Add
1904 saber.suppress and tests directory. Add config.status to
1905 the release (it will say "none").
1907 coredep.c: Minor formatting fixes.
1909 These changes were made in early December but only checked in now:
1910 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
1911 nindy-share/nindy.c: lint
1912 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
1913 register values coming back from the target; we store values
1914 in target byte order everywhere.
1916 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
1918 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
1920 * valprint.c (cplus_val_print, val_print_fields): New functions,
1921 which print C++ objects. They conspire to avoid printing a
1922 virtual base class more than once, following all the twists and
1923 turns of C++ virtual base rules.
1924 (val_print): Call the above rather than do it by hand.
1926 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
1927 symbol file, not for added files like shared libs. This really
1928 needs to be generalized to a timestamp per file.
1930 * core.c (cleanup_core): Avoid coredump if no core file.
1932 * config.gdb: Accept -host or -target in place of +host or
1935 * coffread.c (find_linenos): Avoid desupported BFD interface
1936 to line numbers. We still read them manually rather than using
1937 BFD's "generic" features.
1939 * gdbrc.tex, threecol.tex: Add GDB reference card and its
1941 Makefile.dist: Add refcard to OTHERS list for creating tar files.
1943 * Makefile.dist: Eliminate use of $< in explicit targets.
1945 * readline/Makefile: Use $< rather than $*.c, which does not
1946 include the VPATH in GNU Make.
1948 * tconfig/i960-bout, tconfig/i960-coff: These are identical
1949 copies of tconfig/i960, added for global configuration
1950 compatability. All i960 versions can read both coff and b.out.
1952 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
1953 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
1956 * TODO: Think of more things to do.
1958 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
1960 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
1961 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
1962 64-bit float conversion.
1964 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
1965 equivalent to sun?os4 so global config works.
1967 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
1971 * main.c: Only declare linesize once; declare pagesize not at
1972 all, since it is never used.
1973 (main): Clear newly allocated line before it is used.
1975 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
1977 Further stabilization for the Intel 960.
1979 * Makefile.dist: Parameterize the location of the "include"
1980 and "bfd" directories, as well as "getopt". Add symfile.c.
1981 Link in both dbxread and coffread. Fix up "make depend" to
1982 rewack the locations of include, bfd, and getopt in its output.
1984 * README: Document moving include files, improve some of
1987 * coffread.c: Move common code out to symfile.c. Change
1988 symbol_file_command style interface to use new *_symfile_init
1989 and *_symfile_read interface under BFD. Use BFD internal
1990 info to locate line table, symbols, etc.
1992 * core.c (core_fetch_registers): Rename to get_core_registers
1993 to avoid confusion with fetch_core_registers.
1994 (register_addr): Move to coredep.c, which is already machine
1995 dependent. This leaves core.c pretty clean of dependencies.
1997 * coredep.c (register_addr): Accept this routine from core.c.
1999 * dbxread.c: Move common code (with coffread.c, etc) into new
2000 symfile.c. Each psymtab now contains a pointer to the
2001 format-dependent function that knows how to read it in. Make
2003 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2004 (process_one_symbol): Add code to complain about a "compiler bug
2005 we muzzle here", if we actually see it.
2007 * eval.c (evaluate_subexp): Insert missing "break" statements
2008 in code that determines whether a variable is an lvalue in
2009 memory, register, or whatever. I detected this via a compiler
2010 bug in which it *almost* mashed out the whole switch statement.
2012 * gdb-int.texinfo: Add minor sections on configuring gdb for
2013 release, and about the README file.
2015 * infcmd.c (registers_info): Fix formatting somewhat. Still
2016 not as pretty as before, but it handles byte swapping.
2018 * remote-nindy.c: If data cache routines are interrupted while
2019 waiting for the remote end, be sure that any uninitialized cache
2020 blocks are on the free list, not on the valid list!
2022 * symfile.h: Flesh out this header file with all the various
2023 routines and variables that have been merged in from dbxread.c
2024 coffread.c, and symtab.c to symfile.c.
2026 * symfile.c: New file, containing code common to dbxread.c,
2027 coffread.c, and some code from symtab.c. All generic code for
2028 reading symbol files should be in here now.
2029 (unrecord_misc_function): Remove unused function.
2031 * symtab.h: Remove file-reading things to symfile.h.
2033 * symtab.c: Remove file-reading things to symfile.c.
2035 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2036 to decode i960 fault types.
2038 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2039 target.c: Change type of the "resume" function from int to void,
2040 since its result was never used.
2042 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2044 * main.c: Replace "stupid" with "caution"; you now "set caution
2047 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2049 * infcmd.c (do_registers_info): Call val_print to deal with the
2050 byte order of the registers being printed. FIXME, this makes
2051 the formatting of the output uglier.
2053 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2054 defined, call it for signals the debugger doesn't itself use.
2055 The i960 uses this for more detailed fault information.
2057 * remote.c (remote_open): If arg is null, print help rather than
2060 * sparc-xdep.c (register_valid): Avoid declaring size, since
2061 various modules will think of various sizes depending on the
2062 architecture of their tm-file. FIXME, we need protection against
2063 actually entering one of those modules, which would clobber
2064 storage if not for the target architecture compiled into gdb.
2066 * stack.c (up_command, down_command): Always print the frame
2068 (up_silently_command, down_silently_command): New commands
2071 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2073 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2074 more parameters than it used to.
2076 * findvar.c (registers): Increase slop to 256 bytes, which should
2077 protect us against even most RISC machines with large register
2079 (locate_var_value): Move declaration inside related ifdef.
2081 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2082 throughout, to avoid throwing away buffered input from the board.
2083 (nindy_wait): Supply_register takes addr_of_value, not value.
2084 (i960_print_fault): Renamed from i80960_fault.
2085 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2086 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2088 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2089 we can set the PC in the call to proceed(). Unpush nindy_ops
2090 before pushing it on top, to avoid message to user. Eliminate
2091 commentary from Unix machines that just misleads here.
2092 (reset_command): Fix error message to suggest target command.
2094 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2096 Release 3.92.5 as frozen.
2098 Stabilize the merged release...with help from lint, Saber C,
2101 Everywhere: Add include files needed to declare return types
2102 of functions called.
2104 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2106 * breakpoint.h: Add undeclared breakpoint functions, and some
2107 functions for display handling since I couldn't think of a better
2110 * breakpoint.c (insert_breakpoints): Make code for disabling
2111 shared library bkpts more likely to work. It's used when we
2112 rerun a program and stop before the shared library has been
2114 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2115 cast from pointer, so it squeezes through catch_errors.
2116 (bpstat_stop_status): Fix logic broken some time ago. We now
2117 always create a bpstat if the stop address matches a breakpoint,
2118 even if we don't stop there -- just like the old code used to do
2119 before I got my fingers into it (sigh).
2120 (breakpoint_1): Print "ignore count" after "stop only if"
2121 condition, since that's how it actually works.
2122 (mention): Handle watchpoints as well as breakpoints.
2123 (watch_command): use set_raw_breakpoint and mention to do most
2124 of the work (and initialize all the fields!). Only pass one
2125 arg to parse_c_expression, since that's all it takes.
2127 * command.c (not_just_help_class_command): Rename arg to args
2128 since we ignore "unused argument" warnings on vars named "args".
2129 inflow.c (child_terminal_info): ditto.
2130 infptrace.c (kill_inferior): ditto
2131 main.c (catch_errors, version_info, quit_command, pwd_command,
2132 source_command, dump_me_command, editing_info,
2133 set_history_size_command, set_history, show_history,
2135 stack.c (locals_info): ditto
2136 target.c (target_files_info): ditto
2137 valprint.c (set_input_radix, set_output_radix): ditto
2139 * core.c: Remove old variables for handling core and exec file
2140 sections (data_start, data_end, stack_start, stack_end,
2141 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2142 text_end, exec_data_start, exec_data_end, text_offset,
2143 exec_data_offset, data_offset, stack_offset). They're
2144 superseded the more general build_section_table and
2146 (get_exec_file): Mention the `file' command.
2147 (read_memory_check): Rename to memory_error, and only call it
2148 in the case of an actual error.
2149 (read_memory, write_memory): call memory_error.
2150 (core_fetch_registers): Register section name is ".reg".
2152 coredep.c: Remove a bunch of crud now that all this file does
2153 is pull the registers out of a core file.
2154 (fetch_core_registers): Rewrite to actually work, I hope.
2156 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2157 Replace index() with strchr(). Remove all the pre-BFD macro
2158 definitions for accessing the symbol file.
2159 (struct dbx_symfile_info): Encapsulate the information that
2160 dbx_symfile_init needs to pass to dbx_symfile_read in this
2163 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2164 dbx_symfile_discard): Rearrange symbol file reading to divide
2165 the format-specific part from the format-independent part,
2166 leaving the format-independent part such as file name expansion
2167 and opening in symtab.c. This replaces
2168 partial_symbol_file_open and partial_symbol_file_read.
2169 Symbol_file_read, add_file, add_file_target_command,
2170 add_file_addr_command move to symtab.c. Pass an explicit
2171 "mainline" flag for when reading the main symbol table, rather
2172 than relying on the offset address to be zero or nonzero.
2174 (dbx_symfile_read): Don't allow void *'s to be printed as
2176 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2177 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2178 macro" debug version really work.
2179 (read_dbx_symtab): Remove unref'd parameter inclink.
2180 Avoid swapping N_SLINE symbols, for speed.
2181 Merge N_TEXT!N_EXT case with the other external symbol
2182 definitions' case. Add comments.
2183 (start_psymtab): Allocate the symfile name in the psymtab on
2184 the psymbol_obstack, rather than using the caller's storage.
2185 (end_psymtab): Only allocate a dependencies list if there are
2187 (psymtab_to_symtab_2): Use BFD when reopening file to read
2188 its symbols for real.
2189 (read_struct_type): Add FIXME comments where it needs work
2191 (read_huge_number): Add FIXME about overflows.
2192 (read_range_type): Add FIXME about comparing a long to 1<<32.
2194 * coffread.c: Minor changes to move things closer to the new
2195 regime with symtab.c and dbxread.c Major work is still needed
2198 * exec.c (exec_file_command): Remove old variables (see core.c
2200 (xfer_memory): If memory transfer is right at the end of a
2201 section, don't lose.
2203 * findvar.c (get_saved_register): If value is in a real
2204 register, LVAL is lval_register, not lval_memory.
2206 frame.h: Declare print_sel_frame and record_selected_frame.
2208 gdb-int.texinfo: New file, for GDB internals documentation.
2209 Very simple, unformatted doc of cleanups is there for now.
2211 gdbcore.h: Remove obsolete variables that described a.out
2212 section addresses and offsets. (See core.c above.)
2213 Declare fetch_core_registers and registers_fetched.
2215 getopt.c: Declare char *alloca(); even on SPARC.
2217 infcmd.c (run_command): Call target_kill rather than
2219 (step_command, next_command, stepi_command, nexti_command):
2220 Declare from_tty parameter even though we don't use it.
2221 (run_stack_dummy): argument BUFFER is a char array, not
2222 a pointer to REGISTER_TYPE.
2223 (finish_command): using_struct_return needed a value *,
2224 not a struct symbol *.
2226 * infptrace.c (child_xfer_memory): To avoid dependency on
2227 where sections are in memory, try PT_WRITE_D and if that fails,
2228 try PT_WRITE_I. Most Unixes don't care which you use.
2230 * infrun.c (step_resume_break_shadow): Change to array to
2231 match other breakpoint shadow storage.
2232 (clear_proceed_status): Pass address of bpstat to
2233 bpstat_clear, not the bpstat itself.
2234 (child_create_inferior): FIXME comment about if the child
2236 (start_inferior): Remove old function.
2237 (child_open): Use target_kill rather than kill_inferior.
2238 (wait_for_inferior): Ditto.
2239 (insert_step_breakpoint, remote_step_breakpoint): Use
2240 new step_resume_break_shadow.
2242 * inftarg.c (child_wait): If all child processes die,
2243 pretend that the one being waited for exited with signal 42.
2245 * main.c (command_line_input): When scanning for comments,
2246 don't coredump on unclosed quotes.
2247 (quit_command): Use target_kill rther than kill_inferior.
2248 (_initialize_main): Rename class_user from "user" to
2251 * printcmd.c (print_command_1): Initialize "fmt" if no format
2252 is specified by the user.
2253 (print_frame_args): Only add to args_printed if we are
2254 actually fetching args from the stack (avoiding undefined
2256 (_initialize_printcmd): Remove bogus \{ from string.
2258 * remote-eb.c (eb_open): Avoid coredump on no argument.
2260 * remote-nindy.c: Bring out of Intel environment into new
2261 target environment. Remove all conditional compilation on
2262 I80960. Massive hacking throughout.
2263 (nindy_xfer_inferior_memory): New routine stolen from
2265 (nindy_create_inferior): New routine pieced together, probably
2266 not quite working yet.
2267 (nindy_ops): New target_ops struct for nindy.
2269 * remote-vx.c: Use write_memory rather than target_write_memory
2270 to get error checking.
2271 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2273 (vx_create_inferior): Use target_terminal_ours...
2275 * signame.c (_initialize_signame): Always initialize, since
2276 we need the table for things other than psignal.
2278 * solib.c (solib_add): Use symbol_file_add, not add_file.
2279 (solib_address): Return boolean result rather than struct
2280 pointer which nobody else knows the type of.
2282 * sparc-tdep.c, valops.c: Use write_memory rather than
2283 target_write_memory, to get error checking.
2285 * stack.c (locals_info, catch_info, args_info,
2286 get_selected_block, frame_command, up_command): Use
2287 target_has_stack, rather than have_inferior_p or
2290 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2292 * symfile.h: New file, defining the interface between the
2293 generic and object-file-specific symbol reading code.
2295 * symtab.c: Move generic symbol-reading interface to symtab.c,
2296 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2297 table to map BFD targets to symbol-reading modules in GDB.
2298 Change index to strchr.
2299 (lookup_struct_elt_type): Use error() rather than hand-made
2300 simulations thereof.
2301 (lookup_partial_symbol): Speedup slightly when length == 0.
2302 (symbol_file_add): New function.
2303 (symbol_file_command): Call it.
2304 (symfile_open, symfile_init): New function.
2305 (add_file_target_command, add_file_addr_command): moved from
2308 * target.c (target_command): use target_kill.
2310 * target.h (target_files_info): Don't declare, never called
2313 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2314 files to determine stack end address.
2316 * valarith.c (value_x_binop, value_x_unop): Change error message
2317 to be more useful. Pass proper argument to value_struct_elt.
2319 * valops.c (value_assign): FIXME comment that long long
2320 bitfields will break here.
2322 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2323 Update `make saber_gdb' to work better.
2325 * TODO: A woman's work is never done.
2327 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2328 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2329 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2330 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2331 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2332 valops.c, valprint.c, exec.c: Lint.
2335 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2337 Continuing Intel 960 port merge of GDB.
2339 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2340 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2341 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2342 Wack over "make depend" so it handles files in subdirectories
2343 vx-share, nindy-share, bfd, and in the current directory.
2345 * blockframe.c (get_prev_frame_info): Remove fatal error
2346 if stack not defined.
2348 * core.c (core_open, core_detach): New functions that handle
2349 the old "core-file" command as "target core" and "detach" instead.
2350 (core_file_command): Call them.
2351 (core_xfer_memory): Use common routine xfer_memory.
2353 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2354 dbxread now uses bfd for everything but symbol reading itself.
2355 BFD internals are used to drag out the relevant file offsets.
2356 (partial_symbol_file_open): Change args all around for BFD.
2358 * symtab.c: Rename "value" to "val" everywhere, so we can
2360 (symbol_file_command): New command, moved from dbxread.c
2361 and coffread.c. It uses BFD to read the file, then vectors
2362 based on its type, to dbx or coff symbol readers.
2363 * symtab.h: Extern a few vars for symbol_file_command.
2365 * target.h: Breakpoint takes a char * save area, not a char **.
2367 * valprint.c (val_print): When unpacking bitfields, offset
2368 the address in gdb of the value, if it is declared with a shorter
2369 type. Remove the last "runtime kludge test" of host byte order.
2371 * utils.c: Remove old my_bfd_read routine.
2373 * stack.c (frame_info): Use target_has_stack. Print program counter
2374 register's actual name rather than "pc", since it's called the
2375 "ip" (instruction pointer) on the i960 (sigh).
2377 * target.c (target_command): Add command for selecting a target
2378 type and calling its open routine. This is used for initiating
2379 communication with a particular target, in a generic way.
2381 * tm-i960.h: Update for modern gdb. Remove semicolons from
2382 various macros. Handle reading struct return convention, and
2383 error-out attempts to return structs with the "return" command.
2384 Be sure gdb doesn't think we know how to call functions in the
2387 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2388 to i960_xxx in lower case.
2389 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2390 not being defined yet.
2392 * remote.c (remote_open): Call start_remote to initialize
2393 wait_for_inferior during open.
2394 (remote_xfer_inferior_memory): Return length written rather
2397 * remote-vx.c (target_command -> vx_open): Use new generic
2399 * remote-eb.c, inftarg.c, exec.c: ditto.
2401 * infrun.c: Fix comments.
2402 (attach_program -> child_open): Use new generic target command.
2403 (wait_for_inferior): Clear saved register values before target_wait,
2404 so target_wait can set some of them if convenient.
2406 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2407 Return success indicator, not void.
2408 (child_xfer_memory): Avoid fetching initial word if we'll
2409 overwrite it anyway.
2411 * infcmd.c (attach_command): Use new generic target open routine.
2412 (_initialize_infcmd): Update doc on attach and detach commands.
2413 (do_registers_info): Merge in a byte-order problem as a FIXME
2416 * findvar.c (find_saved_register): Avoid problem in current frame.
2417 (read_relative_register): Ditto.
2418 (write_register): Convert byte order on the way out.
2420 * exec.c (file_command): Add.
2421 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
2422 (xfer_memory): Common function between core_xfer_memory and
2424 (exec_xfer_memory): Use it.
2426 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
2428 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
2429 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
2430 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
2432 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
2434 Merge Intel 960 port of gdb, continuing...
2436 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
2437 symbol_file_command): Pass from_tty arg to hush 'em up.
2439 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
2440 Add magic numbers for 960 COFF format.
2442 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
2444 Merge Intel 960 port of gdb, from Intel "1.2" release.
2446 CHANGE_LOG entries from their port, which was based on
2449 Thu Sep 6 11:02:22 PDT 1990
2450 Remove temp file if download is interrupted.
2452 Wed Aug 1 09:08:33 PDT 1990
2453 Now uses binary protocol to talk to NINDY.
2454 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
2455 Times out after 5 seconds when trying to talk to NINDY.
2457 Tue May 29 12:54:49 PDT 1990
2458 Added variable baud rate (-b switch).
2459 Source code reorganization.
2461 Thu Apr 26 11:09:55 PDT 1990
2462 More cleanup of batch mode; specifically, execute "-s", "-e", and
2463 "-se" switches as soon as they are encountered on the invocation line.
2465 Fri Apr 20 13:47:15 PDT 1990
2468 Thu Apr 19 09:54:28 PDT 1990
2469 Add 'reset' command.
2471 Wed Apr 18 09:48:07 PDT 1990
2472 After opening remote tty, wait for 1 second to go by without input
2473 from it before trying to talk to NINDY (fixes problems with the
2474 Heurikon HK80/V960E).
2476 Mon Apr 4 16:33:05 PDT 1990
2477 Some output was not being suppressed in 'batch' mode.
2479 Thu Mar 22 15:31:11 PST 1990
2480 Ask user if old symbol table should be deleted when new file is
2483 Allow user to run a program downloaded before gdb960 was brought up.
2485 Correct "exec-file" help message for i80960 context.
2487 Correct bug in calculating user space address: could occasionally
2488 corrupt user program.
2490 Make sure to zero low-order bits in rip's because of bug in 960CA
2491 A-step part: could cause operation faults when "next"ing across
2494 Correct bug that made it impossible to get source line numbers for
2495 code loaded at addresses higher than 0x7fffffff.
2497 Wed Jan 10 12:43:22 PST 1990
2498 Open remote tty for exclusive use.
2500 Fri Jan 5 12:14:42 PST 1990
2501 Correct disassembly (CA manual was right after all):
2502 opcode for sysctl is 0x659
2504 Mon Oct 23 12:03:04 PDT 1989
2505 Use G960BASE and G960BIN environment variables to find 'sx' utility.
2507 Mon Oct 16 14:15:09 PDT 1989
2508 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
2510 Mon Oct 2 15:56:31 PDT 1989
2512 Added 960CA disassembly support.
2514 To simplify maintenance:
2515 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
2517 - eliminated opcode.h: incorporates tables into i960-pinsn.c
2518 - moved 960-specific routines from i960-pinsn.c to i960-md.c
2519 - made disassembly interface identical to that in gdmp960.
2523 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
2525 * target.h: Allow targets to stack. Add target_has_memory,
2526 _registers, etc. Restructure memory access and "info files"
2527 to walk the target stack.
2528 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
2529 target.c: Change tables to match target.h.
2530 * inflow.c (child_mourn_inferior): pop child_ops.
2531 (generic_mourn_inferior): Use new has_stack flag.
2532 * infptrace.c (child_xfer_memory): New memory regime.
2533 * inftarg.c (child_files_info): New "info files" regime.
2534 * remote-eb.c: New memory regime, new info files.
2535 * remote-vx.c: New memory regime, new info files. Now use
2536 separate targets for VxWorks attachment to machine, and
2537 actually running a process under VxWorks, since one has
2538 stack & execution & regs and the other doesn't.
2539 * remote.c: New memory regime, new info files.
2540 * sparc-xdep.c (fetch_core-registers): New memory regime.
2541 * target.c: New routines and support for stacked targets,
2542 new memory regime, new info files regime.
2545 Generalize section handling for an arbitrary number of sections,
2546 including use of the new BFD (binary file) library.
2547 * gdbcore.h: Add struct section_table.
2548 * exec.c (build_section_table): Iterate all sections and
2549 record what gdb needs to know about them.
2550 (exec_command): Use it.
2551 (exec_xfer_memory): Use the table.
2552 (exec_files_info): Print the table.
2553 * core.c (core_file_command, core_xfer_memory, core_files_info):
2555 * source.c (find_source_lines): Use bfd_get_mtime.
2556 * dbxread.c: Quick changes to make it compile with new BFD.
2557 * utils.c (error): Avoid using bfd_error in generic routines.
2559 * core.c (core_fetch_registers): Get from the ".regs" section of
2561 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
2563 * inferior.h (attach_flag): Export.
2564 * infcmd.c (run_command): use new target_create_inferior.
2565 * infrun.c (child_create_inferior): Don't return result.
2566 * Makefile.dist (VERSION): 3.91.4.
2568 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
2570 * breakpoint.c (bpstat_num): Handle breakpoints which have
2571 since been deleted, such as temporary breakpoints.
2572 infcmd.c (program_info): ditto.
2574 * core.c (core_file_command): Display the frame where the core
2579 * remote-vx.c (target_command): Merge in target command from
2580 targ-vx.c. A few other cleanups.
2582 * TODO, Projects: Lots more stuff to do...
2584 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
2586 Massive changes to wall off the remote-debugging interface
2587 behind a function vector. The port to handle VxWorks targets
2588 is also part of this.
2590 All files: Replace references to renamed functions,
2591 remove references to remote_debugging, remove references to
2592 have_include_file, have_core_file in favor of target_has_stack,
2593 target_has_memory, etc.
2595 * Modularize the breakpoint interface.
2596 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
2597 a breakpoint instruction.
2598 breakpoint.c: struct breakpoint's shadow_contents now sized as
2600 (insert_breakpoints): Vector to target to install breakpoints.
2601 (remove_breakpoints): Vector to target here too.
2602 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
2603 sparc-tdep.c (single_step): Use new breakpoint interface for
2604 the single-step breakpoints.
2605 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
2606 New file, contains routines to insert and remove breakpoints by
2607 reading out the old contents and later replacing them. This is
2608 how ptrace breakpoints work, and many remote systems as well.
2610 * tm-vxworks68.h: New config file, overrides a few things for
2611 Wind River's preferences.
2613 * target.h: New file, for transfer vector used to talk to the
2614 inferior (child, attached, core, exec, remote, etc). All accesses
2615 to the thing being debugged should come through these vectors.
2616 target.c: New file, routines to handle transfer vector.
2617 (various files): Add transfer vectors XXX_ops for the various
2618 targets and pseudo-targets (core files, etc) we support.
2620 * breakpoint.c (bpstat_stop_status): Further explorations of
2621 watchpoints and why things don't work all the time.
2622 (bpstat_alloc): New fn to allocate a bpstat and chain it.
2624 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
2625 the local gdbinit if it doesn't already have it.
2627 * core.c (core_ops): add and install.
2628 Allow core debugging without exec file.
2630 * dbxread.c (free_and_init_header_files): Merge two fns.
2631 (end_symtab): Free named symbol table when a new version comes in.
2632 (read_dbx_symtab): Relocate all kinds of symbols with base
2633 address. First step toward handling different text, data, bss
2635 (add_file_addr_command): Renamed add_file_command.
2636 (add_file_command): Vector to remote handler.
2637 Add "load" as an alias for "add-file" command.
2639 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
2640 non-returning functions.
2642 * exec.c: Add exec_ops, and push it as a target when an exec
2645 * infcmd.c (run_command): Pass executable file name and arg list
2646 separately when starting an inferior. Permit "run" when no exec
2647 file is specified, for VxWorks.
2648 (detach_command): Move to child_detach in inftarg.c.
2650 * inftarg.c: New file. Unix-child-specific routines, and the
2651 child_ops structure.
2653 * inferior.h (registers): Export "registers" as the way for
2654 target dependent register handlers to find gdb's local copy of
2655 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
2656 since it is now used by places that want wait_for_inferior to
2657 handle the grunge but want to see every trap from the inferior.
2659 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
2660 Eliminate remote_debugging hooks in terminal handling.
2662 * infrun.c: Replace start_inferior with child_create_inferior.
2663 Move all the hair of Unix shells and ptrace idiosyncracies into
2664 child_create_inferior, so remote handlers don't have to deal.
2665 Remove running_in_shell. Rename stop_after_attach to
2666 stop_soon_quietly, and use it in a few other places where we want
2667 to just call wait_for_inferior and get control back on the first
2668 trap. trap_expected now never takes a value > 1.
2669 (init_wait_for_inferior): Initialize static vars when a new
2672 main.c (gdbinit): Add new hook for .gdbinit file name, let
2673 it be overridden by config files as GDBINIT_FILENAME.
2674 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
2675 Both of these are used for VxWorks gdb.
2677 mcheck.c: rename include file "gmalloc.c" to avoid problems
2678 with system include file "malloc.c".
2680 param-no-tm.h: New include file, same as param.h but does not
2681 include the default "tm.h" file. This is used in files where
2682 the target is known, e.g. remote-eb.c or sparc-xdep.c.
2684 param.h: Now just a shell that includes tm.h and param-no-tm.h.
2686 remote-vx.c: New file, VxWorks remote debugging support. Uses
2687 RPC routines that are shared with the target system, in directory
2690 remote.c: Vectorize remote interface.
2692 source.c: Globalize source_path, and make an alias "l" for "list"
2693 since we now have the "load" command.
2695 sparc-xdep.c: Use new param-no-tm.h.
2697 symmisc.c (free_named_symtab): Add new function from Wind River.
2698 However, ifdef it out for now while we think about what it should
2701 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
2703 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
2704 non-Unix-children handle this with their own code in the target
2707 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
2708 source and target lists. Add vx-share to default list of include
2709 directories. Add new files to src and target lists: mem-break,
2710 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
2711 ${srcdir} versions of munch and createtags are used.
2713 * valops.c (find_function_addr): Split out of call_function.
2714 (call_function_by_hand): Rename call_function; this function
2715 calls functions in the target by laboriously patching the target
2716 word-by-word with the right stack, args, regs, etc.
2719 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
2721 Handle AMD 29000 a bit better.
2723 * remote-eb.c (readchar): Mask received char log to make it readable.
2724 (remote_start): Pass arguments down to executing program.
2725 Make startaddr unsigned.
2726 infrun.c (start_inferior): Accept args, pass them to
2728 infcmd.c (run_command): Pass args down to start_inferior.
2730 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
2731 the target object file format.
2732 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
2734 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
2735 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
2737 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
2739 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
2740 * TODO: We did a few things, we have more to do though.
2742 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
2743 * inflow.c (inferior_died): Clear deferred stores.
2745 * Debug problems with dummy frames and calls to the inferior.
2746 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
2747 * sparc-tdep.c (do_restore_insn): Simplify.
2748 (sparc_frame_find_saved_regs): Simplify and fix what we find.
2749 (sparc_push_dummy_frame): Simplify and fix what we push.
2750 (sparc_pop_frame): Slightly more hair here, deciding whether
2751 we are restoring a saved PC or returning to a return address in %i7.
2752 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
2754 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
2755 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
2756 * obstack.h (chunkfun): ditto.
2757 * defs.h (xmalloc, xrealloc): ditto
2759 * utils.c (quit): Grab the terminal from the child if necessary.
2761 * inflow.c (term_status_command): Rename to term_info, change
2764 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
2765 (is_delayed_branch): Speed up.
2766 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
2767 Still missing some float ops, and needs testing.
2769 * Support for input and output radixes other than base 10
2770 * defs.h (input_radix, output_radix): Declare.
2771 * expread.y (yyparse, parse_number): Handle changes of input
2772 radix, and ambiguous names-or-numbers in radixes >10.
2773 * printcmd.c (print_scalar_formatted): Print formatted hex
2774 numbers in varying column widths.
2775 * valprint.c (val_print): Use output_format to print scalar ints.
2776 (set_input_radix, set_output_radix, set_radix): Create.
2777 (set_output_radix): Set output_format from output_radix.
2778 (_initialize_valprint): add `set radix' but leave the others off.
2780 * main.c (execute_command): Let stupid questions be turned off.
2781 (_initialize_main): Handle "set stupidity", etc.
2783 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
2784 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
2786 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
2788 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
2789 bfd stuff is still screwed up, but with some manual work, it
2792 * breakpoint.c (bpstat_do_actions): Start over if a command
2793 proceeds the inferior, since the inferior will have stopped and
2794 will need to have its new stop-actions taken care of.
2796 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
2797 compiler fits, simplify it.
2799 * gdb.texinfo (directory command): Doc new dir command.
2800 source.c (directory_command): "dir" now puts things on the front
2801 of the path, moves dups up front, and handles multiple names
2802 on the command line, inserting each one in order. It also
2803 blows away cached line and full_filename info.
2805 * stack.c (backtrace_command): Skip "more stack frames follow"
2808 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
2809 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
2810 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
2811 The only odd one was Gould NP1, which had defined vprintf to
2815 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
2816 variable, inspect_it.
2817 valprint.c (print_string, val_print): Use the global inspect_it
2818 to indicate whether to print in Epoch style or normal style.
2820 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
2822 * printcmd.c (call_command): add an alias for the "print" command
2823 which runs expressions and doesn't print the result if void.
2824 (print_command_1): implement it.
2826 * command.c: Remove #if 0'd code. Initialize all the fields
2827 in add_cmd (). Rename do_nothing_command to
2828 not_just_help_class_command, and make it externally visible.
2829 command.h: add user_commands to struct.
2830 * main.c (define_command): Don't overload c->function with a char
2831 string as well as a function pointer.
2833 * eval.c (evaluate_subexp): Reinstall tiemann changes to
2834 calling convention of value_struct_elt () that got dropped in
2837 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
2838 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
2840 * tm-sparc.h (POP_FRAME): replace some constants with defines.
2842 * sparc-xdep.c (store_inferior_registers): defer stores to regs
2843 until a good time (e.g. when we are about to run the child),
2844 saving ptrace calls.
2845 * infrun.c (proceed): handle DO_DEFERRED_STORES.
2846 * tm-sparc.h: define DO_DEFERRED_STORES.
2848 * sparc-xdep.c (store_inferior_registers): when storing float
2849 registers, don't store stack regs too. When storing the SP,
2850 however, DO store the stack regs too. This fixes a bug in which
2851 the dummy frame is not recognized when a call_function finishes,
2852 because its frame pointer (in the stack regs) was never
2854 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
2855 even though we don't know how to read them from an inferior.
2856 valops.c (call_function): Comment about storing SP.
2858 * infrun.c (save_inferior_status): Save away the original bpstat
2859 chain so it can be restored later. Install the copied version for
2860 use by whoever saved the status. It will be blow away by
2861 restore_inferior_status, and the original chain restored. This is
2862 important for people who have pointers into the original.
2864 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
2865 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
2866 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
2869 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
2871 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
2872 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
2873 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
2875 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
2877 * Merge Mike Tiemann's multiple inheritance changes from Sun.
2878 Store the baseclasses in a type struct starting from array element
2879 0 rather than from the unusual array element 1.
2881 dbxread.c: the above.
2882 (virtual_context): Add
2883 Read new debug information about which virtual function table
2884 a virtual function is from, and store it in fn_field.fcontext.
2886 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
2887 TYPE_FN_FIELD_STATIC_P.
2889 symtab.c: the above.
2890 valops.c: the above. Handle pointer casts of object *'s.
2891 (search_struct_method): Add.
2892 (value_struct_elt): First arg is now a pointer to a value, and is
2895 valprint.c: the above.
2896 values.c (value_virtual_fn_field): Add type arg. Handle
2897 offsetting to the proper object when calling virtual fns.
2899 (baseclass_addr): Add valuep arg.
2901 * README: Document the current state of BFD config (missing).
2902 * TODO, ChangeLog, Makefile.dist: Roll version.
2903 * WHATS.NEW: Add summary of changes since 3.5.
2905 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
2907 * dbxread.c (read_struct_type): Clear bit vectors whenever
2909 symtab.c (B_CLRALL): define.
2911 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
2912 using == rather than =. Huh... This fixes the dreaded problem
2913 wherein builtin_type_int becomes TYPE_CODE_FLT.
2915 * core.c (info_files): Show the inferior pid.
2917 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
2918 already knows how to look in the source directory.
2920 * Remove psymtab hair from many places. Remove duplicated code
2921 for searching symbol tables. Hide psymtabs from most places.
2922 Make it fast to get from a psymtab to its symtab.
2924 blockframe.c (blockvector_for_pc): Remove psymtab hair.
2925 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2926 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2927 dbxread.c: export psymtab_to_symtab, make it work if called N times.
2928 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
2929 new symtab completely. New psymtabs get symtab pointer
2930 initialized to zero. Remove MI warning printf.
2931 symtab.h: Comments. Add psymtab to symtab pointer.
2932 (PSYMTAB_TO_SYMTAB): New macro.
2933 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
2934 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
2936 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
2938 (print_frame_info): Avoid special-casing symbols that have not yet
2941 * source.c (open_source_file): Quick path if we have already
2942 located the source file by its full name.
2944 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
2945 find_pc_psymtab. When a name is found in the misc function
2946 vector, search the symbol table for its mangled name, not the
2947 name that the user typed.
2949 * bfd.h: Fix missing comment terminators, make #endifs match.
2951 * valarith.c (value_less): Handle unsigned int comparisons.
2952 Add FIXME about pointer compares, which assume host and target
2953 pointers are the same.
2955 * command.c (do_nothing_command): lint
2956 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
2957 fix comments on debug symbol format for visibility. Actually set
2958 visibility of symbols.
2959 main.c (echo_command): lint; use <readline/history.h>.
2960 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
2961 obstack.h (_obstack_blank): Rearrange pointer math to avoid
2962 pointing past end of allocated memory; saber complains.
2963 obstack.h: Declare the external functions that we use.
2964 valarith.h: use <string.h>
2965 solib.c (solib_add): lint.
2967 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
2969 * main.c (initialize_main): Default info_verbose to off, now that
2970 symbol reading is fast.
2971 (quit_command): Avoid clobbering exec_bfd while quitting.
2973 * Initial BFD (binary file diddling library) merger:
2974 coffread.c: Change AOUTHDR to struct exe_hdr.
2976 core.c: initialize initialized data at compile time.
2977 (core_file_command): Move from coredep.c, convert to bfd.
2978 (xfer_core_file): Convert to bfd.
2979 exec.c (exec_file_command): use bfd routines.
2981 mips-tdep.c: Remove exec_file_command and friends.
2984 * coredep.c: (fetch_core_registers) Convert core_file_command to
2985 fetch_core_registers.
2986 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
2988 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
2989 (my_bfd_read): More bogosity, which I don't think we call.
2990 (program_name): Remove this atrocity asap!
2992 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
2995 values.c: allocate_repeat_value was not clearing the
2996 optimized_out field.
2997 (value_static_field): minor stylistic fix (wrong macro was used).
2998 valops.c (value_struct_elt_for_address): didn't work for C++
3001 * signame.c (_initialize_signame): Initialize signal names once.
3003 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3004 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3005 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3007 * remote-eb.c: Support user-settable baud rates on the serial port.
3009 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3011 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3013 * tconfig/sun3os4: Remove warning about native assembler,
3014 since it also occurs in the xconfig file.
3016 * findvar.c (registers): Allocate some slop after `registers'
3017 to prevent stray accesses from trashing the next variable.
3019 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3020 on the sun-3, by changing the #ifdef from `sun3' (which is not
3021 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3022 vars, which happened to follow `registers' in the executable.
3024 * readline/history.c (history_search): Heed gcc-2's advice
3025 and parenthesize && inside ||).
3027 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3028 tm-29k.c: Insert FSF copyright headers.
3030 * remote-eb.c: Better comments.
3032 * Makefile.dist: Update to 3.91.6.
3033 * TODO: note PREPARE_TO_STORE problem.
3035 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3037 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3039 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3041 * infrun.c (wait_for_inferior, at end): Don't set up
3042 prev_* if the inferior no longer exists.
3044 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3045 CANNOT_EXECUTE_STACK.
3046 valops.c (call_function): Use it.
3048 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3050 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3051 infrun.c (wait_for_inferior, 2 places): Use it.
3053 * values.c (value_being_returned): Only use
3054 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3056 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3057 right thing for remote-eb.c.
3059 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3060 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3062 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3063 (FRAME_FIND_SAVED_REGS).
3065 * findvar.c ({fetch,store}_registers): Check for
3066 REMOTE_{FETCH_STORE}_REGISTER macro.
3068 * findvar.c (get_saved_register): Add argument lval and
3069 change meaning of argument addr.
3070 findvar.c: Change calls to get_saved_register to reflect
3071 new calling convention.
3072 valops.c (value_assign): Use get_saved_register instead of
3073 find_saved_register.
3075 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3077 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3078 an (uninitialized) pointer to one. Use "&" when passing it
3081 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3083 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3086 * coffread.c (symbol_file_command): Put semicolon after
3088 Put safe_to_init_tdesc_context in #if defined (TDESC).
3089 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3090 coffread.c: #include <sys/stat.h>.
3091 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3092 Add missing ')' in check for "lc%" and friends. Remove
3094 Declare read_one_sym() at top of file.
3095 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3096 MC68WRMAGIC can have the same value without causing a duplicate
3099 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3101 * Allow a Makefile to be built without building the
3102 tm and xm file links that screw up builds in subdirectories.
3103 This is done with `config.gdb none', then you can do things
3104 like `make gdb.tar.Z'.
3105 * tconfig/none: Config file for no target system
3106 * xconfig/none: Config file for no host system
3107 * config.gdb: If no TM or XM files are called out by the
3108 host or target file, don't make links for them.
3110 * cplus-dem.c: Add documentation.
3112 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3113 simple error, so the user's gdb doesn't crash due to some object
3114 file problem (e.g. somebody is rebuilding the file out from under
3117 * printcmd.c (print_address_symbolic): demangle the symbol.
3119 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3120 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3121 (alldeps.mak): sort and uniq all results from this; duplicates
3122 hose gdb.tar.Z link building. Remove RCS files from
3123 tconfig and xconfig. Add config files for sun386. Add
3124 a few odd files to OTHERS and HFILES.
3126 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3128 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3129 Roll version number to 3.91.5. Make lint work in bindir.
3131 * README: Document cross-debugging and new file structure.
3133 * blockframe.c: Lint. Include "value.h" to declare read_register.
3134 (find_pc_partial_function): remove duplicate line.
3136 * command.h: Lint. Declare error_no_arg and dont_repeat.
3138 * tm-news.h: Remove inadvertently duplicated stuff.
3140 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3141 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3143 * config.gdb: Allow `config.gdb host target' form. Clean
3144 up previous change that printed bogus messages when you just said
3147 * core.c: #include "command.h" for lint.
3150 * main.c: Remove some casts of enums. Lint.
3157 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3159 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3160 read it from memory. This will allow us to save ptrace calls
3161 eventually. Changed caller single_step too.
3163 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3164 that we aren't going to use, saving many ptrace calls, especially
3165 when watchpointing or single stepping. Use some #define's for
3167 (store_inferior_registers): Ditto.
3168 (core_file_command): Use some #define's for constants.
3170 * tm-sparc.h: Add #define's for some register numbers, so we
3171 can eliminate the use of random constants in sparc-xdep.c.
3173 * stack.c (frame_command, print_frame_info, up_command,
3174 down_command) Remove frame_changed, since it
3175 causes a bug and doesn't seem to do anything useful. In some
3176 places it was used as a flag, in others as a stack level (?).
3178 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3179 default is to use the portable (vprintf) version rather than the
3181 * xm-news.h (MISSING_VPRINTF): Add.
3183 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3185 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3187 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3188 about linking debugged programs -Bstatic in the sun?os4 config
3189 files in tconfig and xconfig subdirectories.
3191 * main.c (main): Remove unreached exit(0) now that we exit
3194 * Create TODO file for online bug list. There are too many
3195 "little" bugs to keep track of on paper.
3198 rather than kingdon@ai.
3200 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3202 * Makefile.dist (VERSION): 3.91.4 now.
3204 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3205 (condense_misc_bunches): Add sanity check that misc_count is
3206 the same as the number of symbols in the bunch.
3208 * coffread.c: rename init_misc_bunches. Pass an argument
3209 to condense_misc_bunches (a zero).
3211 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3212 every time we are called; don't rely on our caller to do it.
3213 (add_file): Remove call to init_misc_bunches.
3215 * mipsread.c: Only warn, don't error, if unknown symbol types.
3216 This keeps an old gdb from falling on its face if it sees newly
3217 extended symbol info. Rename init_misc_bunches.
3219 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3221 * Merge in changes from Per Bothner for DECstations and other
3222 MIPS stuff. The rest is Bothner speaking:
3224 The next message is a merger of Alessando Forin's mips port with
3225 mine. I've tried to use my good if biased judgment to get
3226 the best of both. It *does* need testing.
3228 Some of the changes are general, *not* mips-specific.
3231 Didn't believe in little-endian bit order.
3232 There are still inconsistencies about whether flags
3233 like BITS_BIG_ENDIAN are integer (#if ...) or
3234 boolean (#ifdef ...). I tried to paper over them.
3236 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3237 Moved some misc_function code that was common to
3238 {dbx,coff,mips}read.c to symtab.c.
3239 In the process, I think I cleaned things up a bit.
3240 At the same time, moved obsavestring and obconcat to symtab.c.
3243 Removed obsolete condense_addl_misc_bunches (use
3244 condense_misc_bunches(1) instead).
3247 Needed to include <sys/dir>, at least on DECstations.
3249 valops.c, mips-tdep.c, tm-mips.h:
3250 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3251 conventions (when STACK_ALIGN is insufficient).
3252 Needed on mips, where doubles need 8-byte alignment,
3253 but ints only need 4.
3256 Removed cruft that was not being used.
3260 Print $ before register-names (I think that makes things a little
3262 Never print two instructions, even if one delays.
3263 Removed hex-disassemble set_cmd. (This is not mips-specific,
3264 so I think the argument is whether it is generally worthwhile or not.
3265 I'm inclined to think not, given how easy it is to
3266 convert between radixes in gdb.)
3269 This is basically Alessando's code.
3270 It doesn't use obstacks; I changed it to use obstacks
3271 in a few minor places where using malloc causes a
3272 memory leak. (Probably, more places could/should be changed.)
3273 I added record_misc_function where it was missing.
3274 In symbol_file_command and add_file_command, I tried
3275 to make the code consistent with more recent versions.
3276 Minor sylistic changes in parse_procedure.
3277 Make a .gdbinfo. psuedo-symbol point back to the real
3278 procedure symbol (using the isym field).
3281 This is basically from my port, but with a lot of details
3282 and a number of routines merged in from Alessando's version.
3283 I basically used my code "raw" backtrace (use heuristics
3284 from the actual code, rather than symbol table info) - though
3285 the idea is Alessandro's. I feel my code is a little cleaner
3286 here, particularly in being a little more flexible, such as being
3287 able to handle gcc-produced code (which it now can).
3288 It also doesn't do frame caching (which is not useful
3289 more recent gdb versions).
3290 I also used my code for push_/pop_dummy, more or less.
3291 I tried to incorporate AF's code for testing sigtramp
3292 while backtracing; I probably got it wrong.
3293 Added mips_print_register, which tries to scrunch as much
3294 information as possible on a screen...
3295 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3296 under mips-pinsn.c), I don't see anything mips-specific here,
3297 and I don't see it being all that useful anyway.
3300 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3301 Use more register names (rather than hard-cases numbers).
3303 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3305 * Hack up 3.90.11 changes:
3307 * Makefile.dist (depend): parameterize $(GCC).
3308 Add solib.c and solib.o.
3309 (readline): Fix vpath for both absolute or relative SRCDIR.
3312 Also, let the part I didn't understand at least compile so
3313 I can test the rest. FIXME.
3315 * dbxread.c: Fix thinko using strcmp.
3316 (init_psymbol_list): declare static.
3317 (partial_symbol_file_open): Comment cleanups better, avoid
3318 cleaning up the string table since the caller will do that.
3319 Move the stat for mod time into symbol_file_command, temporarily.
3320 (There should be a mod time for each symbol file, eventually,
3321 to control its rereading. FIXME.)
3323 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3324 SunOS, which gives error for shared libs otherwise. (From
3325 Schaefer, probably FIXME needs work for portability.)
3327 * solib.c: Move #include "param.h" to work.
3328 Lowercase all the Uppercase Letters In the Messages.
3329 (find_solib): Clean up inferior_so_name for debug printouts.
3330 Allow no argument, to mean all shared libraries.
3332 * symmisc.c: include param.h to get CLEAR_SOLIB.
3334 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3336 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
3337 to 3.90.11. ChangeLog entries below are from this.
3339 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3343 * Makefile.dist (HFILES): Add tm-sunos.h.
3345 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3349 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
3353 * sparc-opcode.h Added single-operand version of rett.
3355 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3357 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
3358 Put parens around gcc_p in expansion.
3360 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3362 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
3364 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3366 * Changes for Sun shared libraries:
3367 blockframe.c (find_pc_partial_function): If a non-text symbol
3368 is found, set *address = pc - FUNCTION_START_OFFSET.
3369 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
3370 Disable breakpoints instead of giving an error.
3371 source.c (select_source_symtab): Initialize cs_pst.
3372 symmisc.c: Call CLEAR_SOLIB if defined.
3373 symtab.h: Make text{low,high} CORE_ADDR not int.
3374 (psymtab): New field addr.
3376 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
3377 (record_misc_function): Give correct type for N_DATA symbols.
3378 (condense_misc_bunches): do "misc_function_count = j" regardless
3380 Take code which is shared between symbol_file_command and
3381 add_file_command and put it into partial_symbol_file_{open,read}.
3382 Split add_file_command into add_file_command and add_file.
3383 Make psymtab_to_symtab read in the string table if the file
3385 Two new parameters to read_dbx_symtab and start_psymtab.
3386 tm-sunos.h: New file.
3388 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3390 * infcmd.c: Change cont_command to continue_command and "cont"
3393 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3395 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
3397 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
3399 * values.c (USE_STRUCT_CONVENTION): Check for structures of
3400 size 1,2,4,8 rather than size < 8.
3402 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
3403 as necessary, not just once.
3405 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3407 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3409 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3411 * tm-news.h: Add CALL_DUMMY_*.
3413 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
3415 * config.gdb: In list_host, list_target, use ${i}, not $i.
3417 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3419 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
3421 * sparc-opcode.h: Change all store floating-point state register
3422 instructions to have the right match & lose fields.
3424 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3426 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
3428 config.gdb: If srcdir != ., create readline directory and
3429 copy a makefile into it.
3431 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
3432 consistency with POSIX.
3434 * breakpoint.c (bpstat_stop_status): Disable watchpoint
3435 when we exit its exp_valid_block.
3437 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
3439 * Makefile.dist: Bump version to 3.91.3.
3441 * Clean up handling of breakpoint commands (somewhat).
3442 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3444 inferior.h: Add breakpoint_proceeded to inferior status struct
3445 and globals; save it and restore it.
3446 (clear_breakpoint_commands): Cleanup, remove old #define.
3448 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3449 (save_inferior_status, restore_inferior_status): handle it also.
3450 (proceed): Remove earlier code that set breakpoint_proceeded.
3451 It is now set only in clear_proceed_status.
3452 (clear_proceed_status): Cleanup, use bpstat_clear rather
3453 than clear_breakpoint_commands. No callers need the stop_bpstat
3454 between clear_proceed_status and proceed.
3456 infcmd.c: Add breakpoint_proceeded definition and comment.
3457 (cont_command, jump_command, signal_command): Move call to
3458 clear_proceed_status right next to call to proceed.
3460 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3461 caller's argument while running down the chain of breakpoints.
3462 Use new variable "breakpoint_proceeded" to determine when
3463 a command that it executes moves the inferior past the
3465 (bpstat_clear): Handle NULL argument.
3466 (bpstat_clear_actions): Avoid useless call to
3467 breakpoint_auto_delete.
3468 (delete_breakpoint): Clean up bpstat's that are pointing to
3469 the deleted breakpoint from the stop_bpstat chain.
3470 (breakpoint_auto_delete): Simplify.
3472 * Clean up handling of EOF, error on stdin, etc. This was
3473 prompted by a network problem that caused gdb to go into an
3474 infinite loop filling up its malloc'd memory.
3476 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
3477 not clear_breakpoints_commands, which is now gone.
3478 (main): If command_loop returns (e.g. from EOF on stdin), do
3479 a quit_command (looping back to command_loop if quit_command
3480 doesn't really quit).
3481 (command_loop): check result from command_line_input and
3482 exit if it returns NULL, rather than passing the NULL to
3484 (gdb_readline): Free malloc'd result space before returning
3487 * utils.c (query): Handle C-d to mean "yes", just as if the
3488 input was not a terminal. Also avoid infinite loop if EOF
3489 occurs in mid-input-line before newline. This allows
3490 query to be used at EOF on stdin with reasonable results.
3492 * infrun.c (proceed): Set breakpoint_proceeded.
3494 * values.c (value_as_long): Avoid infinite recursion for enums.
3495 (_initialize_values): Fix typo in help msg (kingdon).
3497 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
3498 RL_LIB for linking. This allows -lreadline for linking
3499 and nothing for dependencies, once readline is a real library.
3501 * config.gdb: Jim Kingdon: give useful error message if the
3502 host or target type is not recognized.
3504 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
3505 it just defines it. Dumb, but deal with it.
3507 * Jim Kingdon suggests:
3508 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
3510 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
3512 * Makefile.dist (VERSION): Bump version # to 3.91.2.
3514 * Clean up Bothner's changes.
3516 * blockframe.c (clear_pc_function_cache): New function.
3517 * blockframe.c: remake cache_pc_function_* static.
3518 * dbxread.c (symbol_file_command): remove references to
3519 cache_pc_function_* variables.
3520 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
3521 * printcmd.c: Avoid kludging a global variable (addressprint)
3522 to avoid printing the address of a string twice. Instead,
3523 pass the format letter 's' down low enough that it can be seen
3524 to avoid this problem.
3525 (print_formatted): Pass format arg to value_print.
3526 (restore_addressprint): Remove function.
3527 (do_examine): Avoid hacking addressprint, cleanups and such.
3528 (print_frame_args): Add a comment to a Bothner change.
3529 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
3530 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
3531 to wipe out the values cached in blockframe.c.
3532 * symtab.c (find_method): Add comment saying how big you must
3533 allocate to be "big enough". Per being terse again.
3534 * valprint.c (val_print): Handle format letter "s" to print
3535 strings without addresses. Add comment to vtbl printing code
3536 which casts with wild abandon. Rearrange reference-printing
3538 @0xaddr: value (print w/addressprint)
3539 value (print w/~addressprint)
3540 @0xaddr (parameter lists w/addressprint)
3541 or nothing (parameter lists w/o addressprint)

3545 * Merge more changes from Per Bothner:
3547 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
3548 annoying) that I tried to improve it. Here are my suggestions.
3550 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
3553 Do automatic de-reference when taking the address of a reference.
3555 Don't deref_ref when printing parameter lists.
3557 More attempts at treating refernences properly.
3559 In val_print, if deref_ref==0, don't print dangling " = ".
3561 Add COERCE_REF macro, which de-references an REF.
3563 * Merge changes from Per Bothner:
3565 * Fixed (Sony news)-specific configuration problems.
3566 * Fixed other problems with using vanilla pcc and libc (enum problems;
3567 assumption that vsprintf exists).
3568 * Some major speed-ups (finc_pc_partial_function now caches a match;
3569 parsing avoids duplicate symbol_lookup calls).
3570 * Changed handling of baseclasses (no longer use baseclasses field
3571 of struct type, use the first n_baseclasses fields instead).
3572 * Various minor changes/fixes, most C++-related.
3575 Cache the most previous match from find_pc_partial_function.
3576 (Save both low and high ends of matching function's pc range.)
3577 This speeds up the loop of infrun.c:wait_for_inferior quite
3578 a bit, and makes step/next commands much zippier.
3580 Added an enum->int cast (otherwise, some compilers barf).
3582 No longer set baseclass offset to 0, since multiple
3583 inheritance now mostly works.
3584 Added a number of casts, to shut up compiler warnings
3585 (after stabs where made enums, not ints).
3586 When discarding a symbol table (in symbol_file_command),
3587 must clear the cache introduced in blockframe.c.
3588 Don't convert $vtbl_ptr_type to vtbl any more.
3589 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
3590 Mask off sign bit emitted by g++ for virtual table offset.
3591 Set voffset to -1 (not 1) for static member functions.
3593 Changed parsing/lexing of names to avoid doing symbol lookup twice
3594 (once when lexing to determine symbol class, once for real).
3595 Now only call symbol_lookup once. Fields of 'this' win especially big.
3597 Subpress printing addr twice in the case of 'x/s addr'.
3599 lookup_basetype_type is no longer used.
3600 Add find_methods as recursive helper function to decode_line_1.
3601 This allows multiple inheritance to work.
3602 Also, once one or more matches has been found, do not look in
3603 base-classes. (Baseclass methods would be overridden, anyway.)
3605 Removed baseclasses array in struct type.
3606 Instead of using baseclasses[i], use fields[i-1].
3607 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
3608 Changed sign convention of voffset (previous was inconsistent).
3610 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
3612 Used to assume existence of vsprintf. Re-written to not need it
3613 if HAVE_VPRINTF is undefined.
3615 typecmp was too pessimistic. Made it less so.
3617 Don't print space after address.
3618 If vtable points to a misc symbol (with 0 offset), print it,
3619 since that indicates the actual class of the object.
3620 Changed ype_print_derivation_info to use new inheritance
3621 scheme (without baseclasses vector).
3623 In value_primitive_field, fixed some bugs left over from previous set of fixes.
3624 Also, changes needed because TYPE_BASECLASSES were removed.
3626 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
3628 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
3631 If there is no path set, and the symbols don't indicate what directory
3632 a file was compiled in, look in the current directory. But either
3633 a path or a known compilation directory will prevent this.
3636 Three independent bug fixes:
3637 * Remove the #if 0 block that breaks some stuff.
3638 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
3639 adapt gdb to either SunOS 4.0.* or 4.1.
3640 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
3643 Instantiate the class T when looking for methods in it. (Tiemann@sun)
3646 (type_print) Demangle the name being printed.
3647 (type_print_base) Handle botched demangling without coredump (tiemann).
3650 (check_stub_method): Document routine.
3651 (tiemann) fix bug for no-arg functions
3652 Avoid clobbering beyond end of malloc'd storage.
3653 Terminate the argument list properly.
3657 * Changes merged by John Gilmore:
3660 In breakpoint_1, use new print_address_symbolic instead
3661 of find_pc_partial_function. (This forces use of assembler-level
3662 addresses, and avoids misleading non-mangled source-level names.)
3664 Generalize ansi argument such that -1 means skip arglist totally.
3665 Removed global variable print_ansi_qualifiers (which made
3666 code non-reentrant), in favor of extra explicit arguments
3667 to internal routines.
3669 Add new helper function print_address_symbolic.
3670 Use find_pc_misc_function instead of find_pc_partial_function
3671 (since we want assembler-level symbols here).
3673 Print unknown function as just "f (...)", not "f (...) (...)".
3674 Use new fputs_demangled explicitly.
3676 Fixed a typing violation (problem: value.h cannot be imported
3677 without renaming many variable in this file).
3678 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
3679 decode_line_1: Moved forward some never-reached code.
3680 Made decode_line_2 skip function prologues correctly.
3682 fputs_filtered should not demangle by default.
3683 Add new fputs_demangled to demangle on demand..
3685 Change value_struct_elt to use value_primitive_field (using recursive
3686 utility function search_struct_field). This allows foo.bar to work
3687 for multiple inheritance (so far only for data fields).
3688 Change check_field in the same way (recursive helper function
3689 to support multiple inheritance).
3690 (Note: there are more of these problems that I haven't fixed.
3691 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
3692 value_of_this: 'this' symbol name is now just "this", note "$this".
3694 Don't print static members.
3695 Avoid printing "members of <type>" if there are none.
3696 Simplified type_print_derivation_info by merging duplicate code.
3697 Remove useless blank lines in type_print_base (ptype command).
3699 Added declaration of new routine value_primitive_field.
3701 Added value_primitive_field which is generalized version of
3702 value_field that can handle multiple inheritance (non-zero offsets etc).
3703 Re-implemented value_field to call value_primitive_field.
3705 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
3707 * infcmd.c -- insert else to avoid 'delete env' coredump when you
3708 delete the whole environment. Karl Berry reported the bug.
3709 * source.c - fix openp to avoid //'s in filenames, which
3710 trigger an Emacs bug causing it to not be able to find files
3711 when running gdb in a window.
3712 * dbxread.c - zap the #if 0 that botches the add-file code.
3713 It seems to work a lot better without all the code commented out.
3715 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
3717 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
3720 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
3722 * Makefile - added a ${CFLAGS} to a couple of entries,
3723 added remote-sa.sparc.c
3724 * added remote.sa-sparc.c, a modification of remote.c
3725 which conducts a dialog directly with the SparcStation prom.
3726 * breakpoint.c, infrun.c, sparcdep.c added
3727 remote_insert_breakpoint(), and remote_remove_breakpoint()
3728 to breakpoint.c instead of directly writing breakpoint instructions.
3729 * sparcdep.c on remote_debugging,there is no need
3730 to remove signle step breakpoint instructions.
3731 * main.c added "-epoch" flag and "int epoch_interface" to main.c
3733 * printcmd.c - epoch interface sends lisp expressions to open up
3734 epoch windows on inspection.
3735 * valprint.c - added arrayprint, and addressprint and made adding
3736 format controls easier
3737 * wait.h added a couple of undef's because we were getting
3738 complaints about WSTOPSIG and WTERMSIG begin redefined.

3834 step_resume_break_address != NULL, even if another_trap.
3835 If trap_expected and we enter sigtramp, then set up a
