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

44 * gdb.texinfo: Updated to include new or old undocumented
45 commands, at least the following (perhaps some others I forgot to

81 * remote.c: Remove decls of memory_insert_breakpoint
82 and memory_remove_breakpoint, no longer used. (Suggestion of
85 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
86 to make it easier to interface to "configure"'d libraries.
88 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
90 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
91 aliases for set/show print.

520 * cplus-dem.c: Use CPLUS_MARKER not '$'. If CPLUS_MARKER isn't
521 defined, define it to '$'.

536 * Makefile.dist (cplus-dem.o): Hack in an #include "param.h"
537 before we compile it.
538 defs.h: Protect against multiple inclusion.

589 * values.c: Rename value_history_info to show_values.
590 (_initialize_values): Rename "info values" to "show values".
592 Sun Apr 14 23:08:34 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
594 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
595 New function to give correct error message.
597 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
599 * target.h: Add to_doc and target_preopen.
600 target.c: Add target_preopen and target_command.
602 (add_target): Call add_cmd and mess with targetlist->doc.
603 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
604 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.

622 Rename add-syms to add-symbol-file.
624 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
626 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
627 * symfile.c (clear_symtab_users_once, cashier_psymtab,
628 free_named_symtabs): Move these routines from symmisc.c.
629 * symmisc.c (same): same.
630 (free_symtab): Make non-static.
631 * symtab.h (free_symtab): Declare as exported void fn now.
632 * dbxread.c (end_symtab, end_psymtab): Change comments.

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

1016 (object search path) as conveniently as the source search path.
1017 * environ.c (set_in_environ): Set some vars in GDB's environment,
1018 in addition to the child's. PATH, G960BASE, G960BIN for starters.

1032 in raw hex as well as float format, regardless of whether it is
1033 a "virtual" convertible register.

1035 regs as a double, just in case it's being used that way.
1036 * values.c (unpack_long): Comment on array/function coercion.
1037 (unpack_double): Argument is in target byte order now. For
1038 integer arguments, just call unpack_long and float the result.
1039 * m68k-tdep.c: include defs.h for "const" handling.
1040 * remote-nindy.c: Use ieee-float stuff.
1041 (nindy_fetch_registers): Unpack double regs to host double, then
1043 (nindy_store_registers): Pack extendeds to host double, flip

1055 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1057 * coredep.c (fetch_core_registers): Pass end-address of register
1058 section to register_addr as expected. Don't call supply_register
1059 if we'd just pass it garbage.
1061 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1063 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.

1108 * inftarg.c (child_detach): Pop the child_ops vector if the
1109 detach is successful.
1110 * remote-nindy.c (nindy_create_inferior): Don't push a new
1111 nindy_ops since nindy uses the same one for execution and memory
1113 * core.c (core_ops): Use child_attach and child_create_inferior
1114 rather than default attach and create_inferior functions.
1116 Handle floating point registers in core files.
1118 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1119 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1120 This version untested since BFD doesn't yet support sun3 core
1122 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1123 conventions. Fix comments and style. This version has not
1124 been compiled yet, since we have no HP inhouse.
1125 * core.c (get_core_registers): Look for two sections, ".reg"
1126 and ".reg2", and pass both to fetch_core_registers sequentially.
1128 Revise directory path yet again.
1130 * source.c (forget_cached_source_info): Not static any more.
1131 (init_source_path): New default source path is "$cdir:$cwd".
1132 (dir_command): Handle variable arguments ($cdir, $cwd).
1133 (source_info): Print "Compilation directory" rather than
1134 "Originally compiled in" to remind people of $cdir.
1135 (openp): If the path contains $cwd, use current directory.
1136 (open_source_file): If compilation directory is known, replace
1137 first $cdir in path with the compilation directory.
1138 (print_source_lines): Even if we can't print the lines, set the
1139 current symtab and line for future commands like "info source" or
1140 "breakpoint". Also, error message now contains the file name,
1141 line number, and file access error message.
1142 (_initialize_source): Fix help text to describe changes.
1143 * main.c (cd_command): Forget cached source info when we chdir.

1149 Byte-swap COFF symbol tables if necessary when reading them in.
1150 Use complain() to replace error message in one spot. Needs
1151 corresponding change in bfd/coff-code.h to make some symbol
1152 swapping routines non-static.
1154 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)

1164 declarations of errno.
1166 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1168 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1169 <rpc/rpc.h> and <rpc/types.h>.
1171 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1173 * i960-tdep.c (examine_prologue): Add new argument limit,
1174 which stops the scan at the end of the prologue, or at the PC.
1175 This fixes a problem where it walks down into the code for the
1176 user's statements if that code looks like function prologues.
1177 Mark Fox and I have been bouncing this code back and forth, making
1178 small changes to it. Callers changed to match.
1180 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1182 Cleanup for gdb-3.94 release final:
1184 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1185 the .c files from vx-share and nindy-share, from the various
1186 macros, since they are not found via ALLDEPFILES.
1187 (SFILES): Add tm-i960.h.
1188 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1189 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files

1196 * am29k-tdep.c: Add contribution line.
1197 (examine_prologue): Cache information about function prologues in
1198 the misc-function-vector to avoid lots of references over the
1199 serial line while examining instructions.
1201 * core.c (core_close): New function made from cleanup_core.
1203 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1204 remote-vx.c, remote.c, target.c, target.h,
1205 Update target_ops vector to add attach, close, and load entries.
1206 Use add_syms_addr_command, not add_file_addr_command, for
1207 add_file. Break out close routine from existing code.
1209 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1210 they are in an obstack.
1211 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1213 (define_symbol): Add symbol type parameter; change callers;
1214 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1215 it to influence the symbol class on the i960.
1216 (define_symbol): Swap LOC_CONST's into target byte order.
1218 * exec.c (exec_close): New function.
1219 (exec_file_command): Call it.
1221 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1222 Fix byte order of frame pointer.
1223 (read_var_value): Result of 0 if var's value can't be found,
1224 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1225 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1226 (locate_var_value): Use read_var_value and use its lazy address
1227 as the location of the var's value. Lint.
1229 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1232 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1233 obsolete Intel versions in favor of vxgdb versions.
1234 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1235 code dealing with byte order of values, which Intel did in host byte
1236 order rather than gdb-4's target byte order.
1237 (i960_frame_chain_valid): Move to nindy-tdep.c.
1238 (examine_prologue, skip_prologue, frame_find_saved_regs,
1239 frame_args_address, leafproc_return, saved_pc_after_call,
1240 pop_frame): Add vxgdb versions from Mark Fox.
1241 (examine_prologue, frame_struct_result_address): Add code
1242 to deal with the saved value of G13 (struct return address
1244 (frame_args_address): Modify Mark's version to prefer the
1245 saved value over the current value in the topmost frame.
1246 Cache result in the frame info to avoid performance hair in
1248 (print_fault): Add gdb960 code for printing faults.
1249 (_initialize_i960): Actually call check_host.
1251 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1252 add stub routines. FIXME, these currently just return zero!
1254 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1255 (attach_command): Call target_attach, not target_open, now.
1257 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1258 (child_attach): Rename from child_open.
1259 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1260 don't confuse it with a zero step_resume_break_address.
1262 * inftarg.c (child_detach): Eliminate inferior_pid test.
1263 (child_files_info): Clean up message a bit.
1264 (child_ops): Use child_attach, not child_open, to attach.
1266 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1267 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1268 findvar.c to here, since it depends on the contents of the
1269 shadow_contents of breakpoints, but keep if #if 0 since it is
1272 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1275 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1276 (ptype_command, display_command): Eliminate have_inferior_p and
1277 have_core_file_p in favor of target_has_stack or
1278 target_has_execution.
1279 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1280 code for actually finding the values of arguments, though we still
1281 keep track of the maximum stack offset for use in printing unnamed
1282 arguments. Handle missing FRAME_ARGS_ADDRESS.
1284 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1285 (struct nindy_regs): Define registers passed to/from nindy.
1286 (nindy_fetch_registers, nindy_store-registers): Translate between
1287 nindy and GDB formats for the registers.
1288 (dcache_init): Statically allocate the cache, since it was being
1289 allocated by a malloc that was never freed anyway.
1290 (nindy_create_inferior): Error, not core dump, if no exec file.
1291 (nindy_before_main_loop): Use target_load, not target_add_file.
1293 * remote-vx.c (net_load): Specify large timeout for load
1294 requests. Allow user to break out with INTERRUPT.
1295 (net_break): Remove useless code, clean up. Change callers.
1296 (parse-args, skip_white_space, find_white_space): Clean up arg
1297 parsing to cope with quoted strings.
1298 (net_wait, net_quit): Never call error, just return status.
1299 (vx_read_register, vx_write_register): Cleanup status checking.
1300 #ifdef the code based on which CPU we are using (960 or 68k),
1301 FIXME, this should be completely general but it isn't yet.
1302 (vx_xfer_memory, vx_resume): Cleanup status checking.
1303 (vx_run_files_info): Improve message.
1304 (vx_load_command): Renamed from vx_add_file_command. Allow load
1306 (net_ptrace): Remove unused routine.
1307 (vx_wait): Adopt code from vxgdb960 to cope with broken
1308 connections to target machine and prompt to disconnect. Remove
1309 debug printouts. Map some EVENT_'s to SIGnals.
1310 (add_symbol_stub, vx_open): Print names of object files we found,
1311 and "ok" if we read their symbols OK. Clarify output in general.
1312 (vx_attach, vx_detach, vx_kill): Add these commands.
1313 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1314 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1315 "info files" output, and create_inferior, since we already have
1318 * stack.c (frame_info): Replace Frame_unknown with 0.
1319 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1320 (return_command): Pop until the PC matches as well as the FP,
1321 so it works even if the FP is shared with another function,
1322 as in "frameless" or "leaf" procedures.
1324 * symfile.c (load_command): renamed from add_file_target_command.
1325 (add_syms_addr_command): renamed from add_file_addr_command.
1326 (add_syms_command): Stub to call target_add_syms.
1327 (_initialize_symfile): Change command names and descriptions,
1328 add-file => add-syms, and load from alias to its own command.
1330 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1331 maybe_kill_then_create_inferior): Default for attempts to start
1332 a process, if one is already running, is to ask about killing
1333 it and retry if yes.
1334 (upstack_create_inferior): #if-0 it, strata obsolete it.
1335 (push_target, unpush_target, pop_target): to_close() a target
1336 before unstacking it.
1337 (target_info): Renamed from target_files_info.
1338 (_initialize_targets): Rename "i files" as "i target", accessible
1341 * target.h: Improve comments about the target_ vectored routines.
1343 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.

1346 (SKIP_PROLOGUE): No longer a no-op.
1347 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1348 (*_REGNUM): Sort register numbers.
1349 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1350 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1351 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1352 are now 10 byte extendeds, not 8 byte doubles.
1353 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1354 for nindy versus vxworks targets. FIXME, this should possibly go
1355 in the target vector.
1356 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1357 frame_saved_regs and arg pointer with each frame.
1358 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1359 (FRAME_ARGS_ADDRESS): Use cached result.
1360 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1361 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1362 (PRINT_RAMDON_SIGNAL): Call print_fault.
1363 (POP_FRAME): Now works.
1365 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1366 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1367 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1368 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1371 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1372 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1374 * valarith.c (value_subscripted_rvalue): Avoid handling
1375 floats and doubles specially; it gave alignment errors. Lint.
1377 * valops.c (value_of_variable, value_of_this): Error if unknown
1380 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1381 to avoid alignment problems.
1382 (value_print): Handle unknown value address.
1383 (cplus_val_print): Two args are ignored; remove them. Change caller.
1384 (val_print): Use unpack_long rather than pointer-deref.
1387 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1388 to avoid alignment problems.
1389 (value_being_returned): Error if return value unknown.
1390 (set_return_value): Add bogosity warning, FIXME. *
1392 * TODO: A woman's work is never done.
1394 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1395 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1396 Add ieee-float.o to OBS.
1397 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1398 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1399 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1401 Changes to generalize the VxWorks RPC protocol slightly, to handle
1402 i960 as well as 68000.
1404 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1405 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1406 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1407 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1408 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1409 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1410 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1411 so they will move in target byte order rather than network
1412 byte order (happens to be the same).
1414 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1416 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1418 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1421 Add contribution lines to various files, showing where they
1424 * breakpoint.c (break_insn, check_break_insn_size,
1425 read_memory_nobpt): Remove to mem-break.c.
1427 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1430 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1431 entry has bad register number. This change is not
1432 tested in this release, FIXME.
1434 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1437 * value.h: Force value's contents field to be aligned to hold
1438 at least a double or a long long (if supported). This avoids
1439 doing bcopy's in and out of the contents field.
1441 (step_1): Avoid coredump under obscure circumstances when we
1444 * symtab.h (misc_info): Add field to misc function vector for
1445 any kind of cached information the target code desires. AMD
1446 29000 uses this to avoid repeating examine_function_prologue's.
1448 * coffread.c: Lint. Remove static symfile, read_section_header.
1449 core.c (have_core_file_p): Lint: remove.
1450 expprint.c (print_subexp): Lint.
1451 infptrace.c, valops.c, valprint.c: lint.
1453 Roll in changes from vxgdb-5.0.1:
1455 * symtab.h: Comment byte order of each address class. Add
1456 LOC_LOCAL_ARG for frame-relative args (960).
1457 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1458 symtab.c, symmisc.c: ditto.
1460 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1462 * remote.c (remote_resume): Error if resume with a signal.
1464 * symfile.c (prim_record_misc_function): Clear misc_info.
1465 (fill_in_vptr_fieldno): Check stub type of arg.
1467 * valops.c (value_cast): Avoid looking up names of types whose
1468 name we don't know, to prevent coredump. Sun CC produces typedef
1469 rtx and the name of *rtx is zero...
1471 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1473 Roll in changes from final AMD 29000 port (Tiemann).
1475 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
1476 for ../include/a.out.encap.h. This might not work now that BFD
1477 is separately compiled. Instead, BFD support for encap will have
1478 to translate machine type 29k into the right COFF_MAGIC.
1480 * infcmd.c: Remove references to inferior_pid that aren't used
1481 in actual ptrace calls; use target_has_execution, etc.
1482 (have_inferior_p): Remove function.
1483 (program_info): Print target info rather than "process number";
1484 avoid gratuitous messages unless from_tty.
1485 (run_stack_dummy, finish_command): Set proceed_to_finish.
1486 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
1487 main.c: Lint. Lose have_inferior_p().
1488 inferior.h (have_inferior_p): Remove, lint.
1489 (proceed_to_finish): Add flag to ask that all regs be saved
1490 by normal_stop, for the few commands that need it, speeding up
1491 serial I/O. Add comments to stop_registers.
1493 * remote-eb.c: Remove newline from breakpoint message we grep
1494 for. Never time out when running the user program.
1498 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1500 Roll in changes from vxgdb-5.0.1:
1502 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
1503 symbol in its raw form, we are processing an unlinked ".o" file.
1504 See if the target environment has assigned it an address, using
1505 target_lookup_symbol (VxWorks does), and enter it into the symtab
1508 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
1509 68k versions for a simpler version that assumes zero FP at bottom.
1510 Fixes bug of truncated stack reports.
1512 * target.h (target_lookup_symbol): Define this routine's args
1513 and result, finally.
1515 * target.c (nosymbol): Default routine for target_lookup_symbol.
1516 (target_default): Default lookup_symbol and call_function too.
1517 (files_info): Only print has_all_memory warning if a non-dummy
1520 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
1521 vx_convert_from_virtual): If target does not have floating point,
1522 zero register "values", and avoid doing cross-net conversions.
1523 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
1524 (vx_open): Rearrange code that attaches to target and reads
1525 symbols for all loaded modules, to work if some of the modules
1526 are not accessible. Add symbol_stub() and add_symbol_stub()
1527 as callbacks from catch_errors(). Allow connect attempt to be
1528 interrupted painlessly with ^C (FIXME, there are still some bugs
1529 if the interrupt happens during symbol reading.). Print
1530 final message with puts_filtered, since symbol messages are
1535 * main.c (catch_errors): Only print errstring if non-null.
1536 (command_loop): Avoid an ioctl per command to test ISATTY.
1538 * remote-vx.c (net_load): make static; avoid sophomoric msg.
1539 (vx_xfer_memory): Return correct result!
1540 (vx_files_info): Indicate whether target has float or not.
1541 (vx_lookup_symbol): Complain, not error, if target gone.
1542 (vx_open): Print "Connected" msg before disabling immediate-quit.
1543 [FIXME: lookup_symbol and vx_open changes need testing.]
1545 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
1546 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
1547 contributor lines and update copyrights to 1991.
1549 Changes from an attempted H-PUX host port:
1551 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
1552 defines PT_ATTACH and PT_DETACH but not PT_KILL.
1553 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
1554 * remote-vx.c: include <sys/time.h> for HPUX.
1555 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
1556 "core_file_command" routine to BFD regime. May not work yet.
1558 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
1560 * xgdb.c: Replace X10 version with some VJ version.
1561 (FIXME: Its copyright assignment is not on record.)
1562 * xgdb.c: Update include files to X11R4 (Xaw crud).
1563 (xgdb_display_source, create_text_widget): fix call to
1564 get_filename_and_charpos. Rewack source window stuff for X11R4
1565 (gleaned from include files, and "nm's" of binary libraries, since
1566 I had no doc available).
1567 (append_selection, append_selection_word): Disable with FIXME
1568 since R4 changed interface here.
1569 (create_buttons): Add back the old set of buttons.
1570 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
1572 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
1573 Roll VERSION to 3.94 (not yet final though).
1575 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1577 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
1578 obstack_int_grow, obstack_int_grow_fast): Eliminate
1579 cast on left of assignment, which gives MIPS cc fits and is
1582 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
1583 F_ALIAS. Use printf, not fprintf, when not passing a file
1585 (compare_opcodes): Check that identical instructions have
1586 identical opcodes, complain otherwise.
1588 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
1589 was reported by Roland McGrath.
1590 (unimp): Only match if exactly zero instruction. (Roland)
1591 (branches and traps): Generate all variations of these
1592 instructions with macros, based on a single call that defines
1593 each condition name and its binary representation.
1594 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
1596 * valprint.c (val_print_fields): Take, and use, format parameter.
1597 This means that "p/x struct" again prints the elements in the
1598 desired format. Changed callers.
1600 * stack.c (frame_info): Use filtered output, and indicate wrap
1601 points. Remove kludgy formatting designed to avoid line wrap.
1603 * utils.c (wrap_here): If the line is already full (because
1604 we had printed a long indent or long wrapped string), do an
1605 immediate newline-and-indent.
1607 * m68k-pinsn.c (print_insn_arg): Bugfix from
1608 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
1609 instruction is incorrectly disassembled as bkpt #8.
1611 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
1612 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
1613 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
1614 and then will dump core (sometimes). I traced it back to an
1615 uninitialized symfile_name in psymtab_to_symtab.
1616 (const_vol_complaint): Add quotes to message.
1617 (define_symbol): Only believe line number if gcc_compiled.
1618 Avoid allocating symbol if we will not return it.
1620 Add target strata support so that newly established targets go
1621 into their right place in the target stack (e.g. a new exec file
1622 doesn't wipe out the ability to access the running process).
1624 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
1625 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
1626 and initialize it properly in all the targets.
1628 * target.h: Document strata. Change return type of push_target.
1630 * target.c (nomemory): new function for dummy memory access.
1631 (tcomplain): Rename complain, now also used in symfile.c.
1632 (push_target): Push targets within strata. New return value shows
1633 whether new target is on top of stack or not. Always keep dummy
1635 (target_files_info): Ignore dummy target.
1637 * core.c (core_open): Warn user, and skip accessing file, if the
1638 core target is not the topmost target in the stack.
1639 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
1642 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
1643 target_ops, it doesn't belong there since we have no regs there.
1644 Change name of target from machine => memory to clarify.
1646 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
1648 * Freeze version 3.93 for release.
1650 * Makefile.dist: Handle vx-share and nindy-share subdirs
1651 properly when building gdb.tar.Z.
1653 * symtab.c: lint; add no_symtab_msg to consolidate the messages
1654 printed in various places, so I could change just one copy.
1656 * dbxread.c, coffread.c: Change references to bfd->iostream
1657 to cast to FILE *, now that BFD avoids needing types defined
1658 in other header files.
1660 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1662 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
1663 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
1664 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
1665 (actually gcc -Wall).
1667 * dbxread.c: Remove first_global_sym, last_global_sym, since
1668 they are never referenced.
1670 * defs.h (baud_rate): Declare.
1671 main.c: Define it, and add the -b option to set it.
1673 * gdb-int.texinfo: Add text on how to define a new host or target
1674 architecture, prompted by Per Bothner's questions about MIPS
1677 * gdb.texinfo: Document "complaints". Change doc of -q since
1678 gdb no longer prints the copyright and blurb if you specify a file
1679 name to be debugged (just like Emacs). Add doc for Nindy-specific
1680 command line flags for specifying target serial port and such.
1681 Update copyright to 1991.
1683 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
1684 has taken over for us the job of ripping up executable files. The
1685 crud caused Per Bothner's port to not compile.
1687 * infrun.c (normal_stop): Avoid printing "Program exited
1688 normally" if we are in batch mode. This allows a GDB which
1689 executes a program on a target system, to behave like a Unix
1690 command (input from stdin, output to stdout, no extraneous
1693 * main.c (main): Allow additional machine-dependent command line
1694 options to be specified with the ADDITIONAL_OPTIONS,
1695 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
1696 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
1697 processing to occur just before the main loop with
1698 BEFORE_MAIN_LOOP_HOOK.
1699 (main): If a "core file" argument is specified, and it is not a
1700 core file, try it as a process ID to attach.
1701 (symbol_completion_function): Attempt to cope with
1702 "show screen-" TAB, not very successfully. This needs more work,
1704 (batch_file): New function, returns whether we are reading
1705 commands from an interactive tty on stdin, or from somewhere else.
1706 Called by normal_stop since it doesn't get from_tty passed down
1707 to it like many commands do.
1709 * remote-nindy.c: Handle command line options for nindy
1711 (nindy_before_main_loop): Prompt user for tty name if they
1712 don't specify it before getting to the interactive command loop.
1714 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
1715 and -r command line options. Also add hook before main loop
1716 to make it easy to specify a tty.
1718 * TODO: More things to do, one done.
1720 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
1722 * dbxread.c: Make complaint() calls pass pointer, not struct.
1723 Add complaints about badly formatted C++ type information
1724 (const/volatile indicator, and parse errors resulting in
1725 error_type). Fix C++ virtual member fn comment.
1726 (read_struct_type): Avoid bumping pointer if we got a parse
1727 error; this prevents our walking beyond the end of a string.
1728 Terminate loop on null char as well as semicolon.
1729 (process_one_symbol): Fix the LBRAC fix so that it uses the
1730 last previous SLINE, FUN, or SO record's PC address. C++ debug
1731 symbols did not have SLINE records in a useful order compared
1732 to the LBRAC records.
1733 (define_symbol): Handle "catch" records.
1735 * symtab.c (check_stub_type): Added new complain
1736 `stub_noname_complain' and added a consistency check to
1737 keep the debugger from crashing when finishing from an
1738 exception frame. A real fix will be needed later.
1740 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1742 * infcmd.c (attach_command): Make global.
1744 * Makefile.dist (REMOTE_OBS): Make these compile by default,
1745 but make them easy to comment out. Perhaps later they should
1746 be enabled by what CPU you configure for? FIXME.
1747 (VERSION): Roll to 3.93.
1748 (pinsn.o): Remove rule for obsolete file.
1749 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
1751 Run down a problem that manifested by printing the wrong function
1752 name in stack traces of read_ofile_symtab. Turned out that the
1753 problem was the SunOS 4.1.1 (and previous) C compiler outputs
1754 the LBRAC symbol with an address in the *data* segment, which
1755 blew our binary search through the blocks.
1757 * dbxread.c: Use the complain() facility consistently to bitch
1758 about problems in the symbol file we are reading.
1759 (finish_block): Add code to check the nesting of the blocks;
1760 complain and Procrust them to fit if wrong.
1761 (make_blockvector): Check the order of the blocks, complain
1762 [but don't cope] if wrong.
1763 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
1764 symbols to be sure their PC value is greater than the last SLINE
1765 (line number) symbol we've seen, complaining and adopting the
1766 SLINE PC value if wrong.
1768 * symfile.h (struct complaint, complaint_root, complain,
1769 clear_complaints): Add.
1770 * symfile.c (complain, complaint_root, clear_complaints): Add
1771 facility to deal with non-fatal complaints and to regularize their
1773 (symbol_file_add): Clear complaint counters to allow new complaints.
1774 (initialize_symfile): Add 'set complaints' and 'show complaints'.
1776 * dbxread.c (dbx_symfile_read): Remember the address and size
1777 of the string table for the main symbol file, so we won't read it
1779 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
1780 to avoid reading the string table yet again. Lint.
1781 (throughout): Improve filtered output, including word wrap.
1782 (read_range_type): Improve Bothner's fix to handle other types too.
1784 * utils.c: Improve line wrap implementation. Handle unlimited
1785 width by making chars_per_line unsigned.
1786 (puts_filtered): New, easy, function.
1788 * defs.h (puts_filtered): add.
1790 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
1791 call the identical sort_symtab_syms() in symfile.c instead.
1793 * expread.y: Suggest the `file' command rather than `symbol-file'.
1795 * command.h (enum var_types): Add zinteger for seroable
1797 * command.c (do_setshow_command): Handle var_zinteger. Restructure
1798 nested if's into a switch.
1800 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
1801 we did not stop because of a breakpoint (it must have been for
1802 some other reason, like a "stepi"), so don't print anything.
1804 * symtab.c: Include <sys/types.h> all the time. Now that BFD
1805 doesn't include <sys/types.h>, old SunOS's require it for
1808 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
1810 A test port of gdb-3.92.6 to the Sony NEWS.
1813 Don't normally link in remote- or vx stuff.
1814 Some of it doesn't compile, and it wastes space for 99% of the users.
1815 Remove reference to no-longer-used HAVE_VPRINTF.
1816 Fixed BFD_DEP typo to BFD_DIR.
1818 Fix cast in arg to bfd_h_getlong.
1819 Make char *prefix be const.
1820 Fix how certain range types are mapped into builtin unsigned int types.
1822 Remove 2 #includes. They cause errors (on Sony, at least),
1823 and aren't needed (they wern't in earlier versions).
1825 print_address_symbolic should never demangle labels
1826 (since it prints *assembler-level* labels).
1828 [This was superseded by the change to printcmd below.]
1831 Add some "volatile" return types to avoid warnings.
1832 If MISSING_VPRINTF add vprintf function and not just macro
1833 (since vprintf is used in printcmd.c).
1835 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
1836 (The latter isn't grokked by some PCC-based compilers.)
1838 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
1840 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
1841 * nindy-share/coffstrip.c
1842 Added some forward declarations (otherwise, gcc complains
1843 about implicit extern redefined as static).
1845 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1847 Changes inspired by Per Bothner:
1848 * printcmd.c (print_address_symbolic): Take additional parameter
1849 specifying whether to demangle.
1850 (print_address): Pass in asm_demangle to control demangling.
1851 (print_address_demangle): New fn, takes explicit arg to control
1853 * utils.c: Add new vars demangle and asm_demangle, and let them
1855 (fputs_demangled): If !demangle, just print the argument.
1856 (fprint_symbol): If !demangle, just print raw symbol.
1857 * valprint.c (val_print): Call print_address_demangle rather than
1858 print_address, to cause demangling to depend on the global
1859 rather than assembler-level demangling setting.
1860 * WHATS.NEW, gdb.texinfo: Document.
1862 * main.c (show_command): Show all settings if no arg.
1863 (initialize_main): Make "info set" the same as naked "show".
1864 * command.c (cmd_show_list): Handle prefix commands in the
1865 list, and print the name of the setting as well as its English
1866 description and value.
1868 Allow gdb functions to specify where a line should wrap if it
1869 exceeds the size of a terminal line. Use it to make the output
1871 * utils.c (set_screen_width_command): New fn, mallocs a buffer
1872 of the right size when screen width changes.
1873 (set_screensize_command, screensize_info): Remove #if 0'd fns.
1874 (wrap_here): New fn, indicates a point in the output where we
1875 should wrap the line rather than just letting it overflow at a
1877 (fputs_filtered): Implement wrapping.
1878 (n_spaces): New fn, returns a pointer to N spaces.
1879 (print_spaces_filtered): Use n_spaces.
1880 * defs.h (n_spaces): Declare.
1881 * stack.c (print_frame_info): Wrap with 4-space indent after
1882 fn name and before filename and line number.
1883 * printcmd.c (print_frame_args): Wrap with 4-space indent
1884 before each argument name is printed.
1885 * valprint.c (value_print): Wrap with no indentation before
1887 (val_print_fields): Wrap with indentation relative to nesting
1888 level before each field name.
1889 (val_print): Wrap with nesting indentation before array elements.
1890 * command.c (do_setshow_command): Avoid extra newlines,
1891 wrap with 4-space indent around values printed, end with period.
1892 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
1894 * breakpoint.c (breakpoint_1): Implement addressprint for
1895 "info breakpoints" display. Change file name and line number
1896 format to " at file:nnn" rather than " (file line nnn)".
1897 * gdb.texinfo: Document.
1900 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1902 Frozen for gdb-3.92.6 release.
1904 README, WHATS.NEW: Update for 3.92.6 release.
1906 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
1907 coffread.o from configs since it is now built by default.
1908 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
1909 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
1910 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
1911 from configs since it is now built by default.
1913 Makefile.dist: Update for release 3.92.6. Handle files that
1914 have been moved to ../include, ../getopt, or ../bfd. Add
1915 saber.suppress and tests directory. Add config.status to
1916 the release (it will say "none").
1918 coredep.c: Minor formatting fixes.
1920 These changes were made in early December but only checked in now:
1921 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
1922 nindy-share/nindy.c: lint
1923 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
1924 register values coming back from the target; we store values
1925 in target byte order everywhere.
1927 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
1929 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
1931 * valprint.c (cplus_val_print, val_print_fields): New functions,
1932 which print C++ objects. They conspire to avoid printing a
1933 virtual base class more than once, following all the twists and
1934 turns of C++ virtual base rules.
1935 (val_print): Call the above rather than do it by hand.
1937 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
1938 symbol file, not for added files like shared libs. This really
1939 needs to be generalized to a timestamp per file.
1941 * core.c (cleanup_core): Avoid coredump if no core file.
1943 * config.gdb: Accept -host or -target in place of +host or
1946 * coffread.c (find_linenos): Avoid desupported BFD interface
1947 to line numbers. We still read them manually rather than using
1948 BFD's "generic" features.
1950 * gdbrc.tex, threecol.tex: Add GDB reference card and its
1952 Makefile.dist: Add refcard to OTHERS list for creating tar files.
1954 * Makefile.dist: Eliminate use of $< in explicit targets.
1956 * readline/Makefile: Use $< rather than $*.c, which does not
1957 include the VPATH in GNU Make.
1959 * tconfig/i960-bout, tconfig/i960-coff: These are identical
1960 copies of tconfig/i960, added for global configuration
1961 compatability. All i960 versions can read both coff and b.out.
1963 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
1964 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
1967 * TODO: Think of more things to do.
1969 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
1971 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
1972 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
1973 64-bit float conversion.
1975 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
1976 equivalent to sun?os4 so global config works.
1978 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
1980 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
1982 * main.c: Only declare linesize once; declare pagesize not at
1983 all, since it is never used.
1984 (main): Clear newly allocated line before it is used.
1986 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
1988 Further stabilization for the Intel 960.
1990 * Makefile.dist: Parameterize the location of the "include"
1991 and "bfd" directories, as well as "getopt". Add symfile.c.
1992 Link in both dbxread and coffread. Fix up "make depend" to
1993 rewack the locations of include, bfd, and getopt in its output.
1995 * README: Document moving include files, improve some of
1998 * coffread.c: Move common code out to symfile.c. Change
1999 symbol_file_command style interface to use new *_symfile_init
2000 and *_symfile_read interface under BFD. Use BFD internal
2001 info to locate line table, symbols, etc.
2003 * core.c (core_fetch_registers): Rename to get_core_registers
2004 to avoid confusion with fetch_core_registers.
2005 (register_addr): Move to coredep.c, which is already machine
2006 dependent. This leaves core.c pretty clean of dependencies.
2008 * coredep.c (register_addr): Accept this routine from core.c.
2010 * dbxread.c: Move common code (with coffread.c, etc) into new
2011 symfile.c. Each psymtab now contains a pointer to the
2012 format-dependent function that knows how to read it in. Make
2014 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2015 (process_one_symbol): Add code to complain about a "compiler bug
2016 we muzzle here", if we actually see it.
2018 * eval.c (evaluate_subexp): Insert missing "break" statements
2019 in code that determines whether a variable is an lvalue in
2020 memory, register, or whatever. I detected this via a compiler
2021 bug in which it *almost* mashed out the whole switch statement.
2023 * gdb-int.texinfo: Add minor sections on configuring gdb for
2024 release, and about the README file.
2026 * infcmd.c (registers_info): Fix formatting somewhat. Still
2027 not as pretty as before, but it handles byte swapping.
2029 * remote-nindy.c: If data cache routines are interrupted while
2030 waiting for the remote end, be sure that any uninitialized cache
2031 blocks are on the free list, not on the valid list!
2033 * symfile.h: Flesh out this header file with all the various
2034 routines and variables that have been merged in from dbxread.c
2035 coffread.c, and symtab.c to symfile.c.
2037 * symfile.c: New file, containing code common to dbxread.c,
2038 coffread.c, and some code from symtab.c. All generic code for
2039 reading symbol files should be in here now.
2040 (unrecord_misc_function): Remove unused function.
2042 * symtab.h: Remove file-reading things to symfile.h.
2044 * symtab.c: Remove file-reading things to symfile.c.
2046 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2047 to decode i960 fault types.
2049 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2050 target.c: Change type of the "resume" function from int to void,
2051 since its result was never used.
2053 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2055 * main.c: Replace "stupid" with "caution"; you now "set caution
2058 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2060 * infcmd.c (do_registers_info): Call val_print to deal with the
2061 byte order of the registers being printed. FIXME, this makes
2062 the formatting of the output uglier.
2064 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2065 defined, call it for signals the debugger doesn't itself use.
2066 The i960 uses this for more detailed fault information.
2068 * remote.c (remote_open): If arg is null, print help rather than
2071 * sparc-xdep.c (register_valid): Avoid declaring size, since
2072 various modules will think of various sizes depending on the
2073 architecture of their tm-file. FIXME, we need protection against
2074 actually entering one of those modules, which would clobber
2075 storage if not for the target architecture compiled into gdb.
2077 * stack.c (up_command, down_command): Always print the frame
2079 (up_silently_command, down_silently_command): New commands
2082 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2084 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2085 more parameters than it used to.
2087 * findvar.c (registers): Increase slop to 256 bytes, which should
2088 protect us against even most RISC machines with large register
2090 (locate_var_value): Move declaration inside related ifdef.
2092 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2093 throughout, to avoid throwing away buffered input from the board.
2094 (nindy_wait): Supply_register takes addr_of_value, not value.
2095 (i960_print_fault): Renamed from i80960_fault.
2096 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2097 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2099 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2100 we can set the PC in the call to proceed(). Unpush nindy_ops
2101 before pushing it on top, to avoid message to user. Eliminate
2102 commentary from Unix machines that just misleads here.
2103 (reset_command): Fix error message to suggest target command.
2105 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2107 Release 3.92.5 as frozen.
2109 Stabilize the merged release...with help from lint, Saber C,
2112 Everywhere: Add include files needed to declare return types
2113 of functions called.
2115 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2117 * breakpoint.h: Add undeclared breakpoint functions, and some
2118 functions for display handling since I couldn't think of a better
2121 * breakpoint.c (insert_breakpoints): Make code for disabling
2122 shared library bkpts more likely to work. It's used when we
2123 rerun a program and stop before the shared library has been
2125 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2126 cast from pointer, so it squeezes through catch_errors.
2127 (bpstat_stop_status): Fix logic broken some time ago. We now
2128 always create a bpstat if the stop address matches a breakpoint,
2129 even if we don't stop there -- just like the old code used to do
2130 before I got my fingers into it (sigh).
2131 (breakpoint_1): Print "ignore count" after "stop only if"
2132 condition, since that's how it actually works.
2133 (mention): Handle watchpoints as well as breakpoints.
2134 (watch_command): use set_raw_breakpoint and mention to do most
2135 of the work (and initialize all the fields!). Only pass one
2136 arg to parse_c_expression, since that's all it takes.
2138 * command.c (not_just_help_class_command): Rename arg to args
2139 since we ignore "unused argument" warnings on vars named "args".
2140 inflow.c (child_terminal_info): ditto.
2141 infptrace.c (kill_inferior): ditto
2142 main.c (catch_errors, version_info, quit_command, pwd_command,
2143 source_command, dump_me_command, editing_info,
2144 set_history_size_command, set_history, show_history,
2146 stack.c (locals_info): ditto
2147 target.c (target_files_info): ditto
2148 valprint.c (set_input_radix, set_output_radix): ditto
2150 * core.c: Remove old variables for handling core and exec file
2151 sections (data_start, data_end, stack_start, stack_end,
2152 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2153 text_end, exec_data_start, exec_data_end, text_offset,
2154 exec_data_offset, data_offset, stack_offset). They're
2155 superseded the more general build_section_table and
2157 (get_exec_file): Mention the `file' command.
2158 (read_memory_check): Rename to memory_error, and only call it
2159 in the case of an actual error.
2160 (read_memory, write_memory): call memory_error.
2161 (core_fetch_registers): Register section name is ".reg".
2163 coredep.c: Remove a bunch of crud now that all this file does
2164 is pull the registers out of a core file.
2165 (fetch_core_registers): Rewrite to actually work, I hope.
2167 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2168 Replace index() with strchr(). Remove all the pre-BFD macro
2169 definitions for accessing the symbol file.
2170 (struct dbx_symfile_info): Encapsulate the information that
2171 dbx_symfile_init needs to pass to dbx_symfile_read in this
2174 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2175 dbx_symfile_discard): Rearrange symbol file reading to divide
2176 the format-specific part from the format-independent part,
2177 leaving the format-independent part such as file name expansion
2178 and opening in symtab.c. This replaces
2179 partial_symbol_file_open and partial_symbol_file_read.
2180 Symbol_file_read, add_file, add_file_target_command,
2181 add_file_addr_command move to symtab.c. Pass an explicit
2182 "mainline" flag for when reading the main symbol table, rather
2183 than relying on the offset address to be zero or nonzero.
2185 (dbx_symfile_read): Don't allow void *'s to be printed as
2187 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2188 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2189 macro" debug version really work.
2190 (read_dbx_symtab): Remove unref'd parameter inclink.
2191 Avoid swapping N_SLINE symbols, for speed.
2192 Merge N_TEXT!N_EXT case with the other external symbol
2193 definitions' case. Add comments.
2194 (start_psymtab): Allocate the symfile name in the psymtab on
2195 the psymbol_obstack, rather than using the caller's storage.
2196 (end_psymtab): Only allocate a dependencies list if there are
2198 (psymtab_to_symtab_2): Use BFD when reopening file to read
2199 its symbols for real.
2200 (read_struct_type): Add FIXME comments where it needs work
2202 (read_huge_number): Add FIXME about overflows.
2203 (read_range_type): Add FIXME about comparing a long to 1<<32.
2205 * coffread.c: Minor changes to move things closer to the new
2206 regime with symtab.c and dbxread.c Major work is still needed
2209 * exec.c (exec_file_command): Remove old variables (see core.c
2211 (xfer_memory): If memory transfer is right at the end of a
2212 section, don't lose.
2214 * findvar.c (get_saved_register): If value is in a real
2215 register, LVAL is lval_register, not lval_memory.
2217 frame.h: Declare print_sel_frame and record_selected_frame.
2219 gdb-int.texinfo: New file, for GDB internals documentation.
2220 Very simple, unformatted doc of cleanups is there for now.
2222 gdbcore.h: Remove obsolete variables that described a.out
2223 section addresses and offsets. (See core.c above.)
2224 Declare fetch_core_registers and registers_fetched.
2226 getopt.c: Declare char *alloca(); even on SPARC.
2228 infcmd.c (run_command): Call target_kill rather than
2230 (step_command, next_command, stepi_command, nexti_command):
2231 Declare from_tty parameter even though we don't use it.
2232 (run_stack_dummy): argument BUFFER is a char array, not
2233 a pointer to REGISTER_TYPE.
2234 (finish_command): using_struct_return needed a value *,
2235 not a struct symbol *.
2237 * infptrace.c (child_xfer_memory): To avoid dependency on
2238 where sections are in memory, try PT_WRITE_D and if that fails,
2239 try PT_WRITE_I. Most Unixes don't care which you use.
2241 * infrun.c (step_resume_break_shadow): Change to array to
2242 match other breakpoint shadow storage.
2243 (clear_proceed_status): Pass address of bpstat to
2244 bpstat_clear, not the bpstat itself.
2245 (child_create_inferior): FIXME comment about if the child
2247 (start_inferior): Remove old function.
2248 (child_open): Use target_kill rather than kill_inferior.
2249 (wait_for_inferior): Ditto.
2250 (insert_step_breakpoint, remote_step_breakpoint): Use
2251 new step_resume_break_shadow.
2253 * inftarg.c (child_wait): If all child processes die,
2254 pretend that the one being waited for exited with signal 42.
2256 * main.c (command_line_input): When scanning for comments,
2257 don't coredump on unclosed quotes.
2258 (quit_command): Use target_kill rther than kill_inferior.
2259 (_initialize_main): Rename class_user from "user" to
2262 * printcmd.c (print_command_1): Initialize "fmt" if no format
2263 is specified by the user.
2264 (print_frame_args): Only add to args_printed if we are
2265 actually fetching args from the stack (avoiding undefined
2267 (_initialize_printcmd): Remove bogus \{ from string.
2269 * remote-eb.c (eb_open): Avoid coredump on no argument.
2271 * remote-nindy.c: Bring out of Intel environment into new
2272 target environment. Remove all conditional compilation on
2273 I80960. Massive hacking throughout.
2274 (nindy_xfer_inferior_memory): New routine stolen from
2276 (nindy_create_inferior): New routine pieced together, probably
2277 not quite working yet.
2278 (nindy_ops): New target_ops struct for nindy.
2280 * remote-vx.c: Use write_memory rather than target_write_memory
2281 to get error checking.
2282 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2284 (vx_create_inferior): Use target_terminal_ours...
2286 * signame.c (_initialize_signame): Always initialize, since
2287 we need the table for things other than psignal.
2289 * solib.c (solib_add): Use symbol_file_add, not add_file.
2290 (solib_address): Return boolean result rather than struct
2291 pointer which nobody else knows the type of.
2293 * sparc-tdep.c, valops.c: Use write_memory rather than
2294 target_write_memory, to get error checking.
2296 * stack.c (locals_info, catch_info, args_info,
2297 get_selected_block, frame_command, up_command): Use
2298 target_has_stack, rather than have_inferior_p or
2301 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2303 * symfile.h: New file, defining the interface between the
2304 generic and object-file-specific symbol reading code.
2306 * symtab.c: Move generic symbol-reading interface to symtab.c,
2307 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2308 table to map BFD targets to symbol-reading modules in GDB.
2309 Change index to strchr.
2310 (lookup_struct_elt_type): Use error() rather than hand-made
2311 simulations thereof.
2312 (lookup_partial_symbol): Speedup slightly when length == 0.
2313 (symbol_file_add): New function.
2314 (symbol_file_command): Call it.
2315 (symfile_open, symfile_init): New function.
2316 (add_file_target_command, add_file_addr_command): moved from
2319 * target.c (target_command): use target_kill.
2321 * target.h (target_files_info): Don't declare, never called
2324 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2325 files to determine stack end address.
2327 * valarith.c (value_x_binop, value_x_unop): Change error message
2328 to be more useful. Pass proper argument to value_struct_elt.
2330 * valops.c (value_assign): FIXME comment that long long
2331 bitfields will break here.
2333 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2334 Update `make saber_gdb' to work better.
2336 * TODO: A woman's work is never done.
2338 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2339 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2340 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2341 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2342 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2343 valops.c, valprint.c, exec.c: Lint.
2346 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2348 Continuing Intel 960 port merge of GDB.
2350 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2351 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2352 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2353 Wack over "make depend" so it handles files in subdirectories
2354 vx-share, nindy-share, bfd, and in the current directory.
2356 * blockframe.c (get_prev_frame_info): Remove fatal error
2357 if stack not defined.
2359 * core.c (core_open, core_detach): New functions that handle
2360 the old "core-file" command as "target core" and "detach" instead.
2361 (core_file_command): Call them.
2362 (core_xfer_memory): Use common routine xfer_memory.
2364 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2365 dbxread now uses bfd for everything but symbol reading itself.
2366 BFD internals are used to drag out the relevant file offsets.
2367 (partial_symbol_file_open): Change args all around for BFD.
2369 * symtab.c: Rename "value" to "val" everywhere, so we can
2371 (symbol_file_command): New command, moved from dbxread.c
2372 and coffread.c. It uses BFD to read the file, then vectors
2373 based on its type, to dbx or coff symbol readers.
2374 * symtab.h: Extern a few vars for symbol_file_command.
2376 * target.h: Breakpoint takes a char * save area, not a char **.
2378 * valprint.c (val_print): When unpacking bitfields, offset
2379 the address in gdb of the value, if it is declared with a shorter
2380 type. Remove the last "runtime kludge test" of host byte order.
2382 * utils.c: Remove old my_bfd_read routine.
2384 * stack.c (frame_info): Use target_has_stack. Print program counter
2385 register's actual name rather than "pc", since it's called the
2386 "ip" (instruction pointer) on the i960 (sigh).
2388 * target.c (target_command): Add command for selecting a target
2389 type and calling its open routine. This is used for initiating
2390 communication with a particular target, in a generic way.
2392 * tm-i960.h: Update for modern gdb. Remove semicolons from
2393 various macros. Handle reading struct return convention, and
2394 error-out attempts to return structs with the "return" command.
2395 Be sure gdb doesn't think we know how to call functions in the
2398 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2399 to i960_xxx in lower case.
2400 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2401 not being defined yet.
2403 * remote.c (remote_open): Call start_remote to initialize
2404 wait_for_inferior during open.
2405 (remote_xfer_inferior_memory): Return length written rather
2408 * remote-vx.c (target_command -> vx_open): Use new generic
2410 * remote-eb.c, inftarg.c, exec.c: ditto.
2412 * infrun.c: Fix comments.
2413 (attach_program -> child_open): Use new generic target command.
2414 (wait_for_inferior): Clear saved register values before target_wait,
2415 so target_wait can set some of them if convenient.
2417 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2418 Return success indicator, not void.
2419 (child_xfer_memory): Avoid fetching initial word if we'll
2420 overwrite it anyway.
2422 * infcmd.c (attach_command): Use new generic target open routine.
2423 (_initialize_infcmd): Update doc on attach and detach commands.
2424 (do_registers_info): Merge in a byte-order problem as a FIXME
2427 * findvar.c (find_saved_register): Avoid problem in current frame.
2428 (read_relative_register): Ditto.
2429 (write_register): Convert byte order on the way out.
2431 * exec.c (file_command): Add.
2432 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
2433 (xfer_memory): Common function between core_xfer_memory and
2435 (exec_xfer_memory): Use it.
2437 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
2439 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
2440 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
2441 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
2443 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
2445 Merge Intel 960 port of gdb, continuing...
2447 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
2448 symbol_file_command): Pass from_tty arg to hush 'em up.
2450 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
2451 Add magic numbers for 960 COFF format.
2453 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
2455 Merge Intel 960 port of gdb, from Intel "1.2" release.
2457 CHANGE_LOG entries from their port, which was based on
2460 Thu Sep 6 11:02:22 PDT 1990
2461 Remove temp file if download is interrupted.
2463 Wed Aug 1 09:08:33 PDT 1990
2464 Now uses binary protocol to talk to NINDY.
2465 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
2466 Times out after 5 seconds when trying to talk to NINDY.
2468 Tue May 29 12:54:49 PDT 1990
2469 Added variable baud rate (-b switch).
2470 Source code reorganization.
2472 Thu Apr 26 11:09:55 PDT 1990
2473 More cleanup of batch mode; specifically, execute "-s", "-e", and
2474 "-se" switches as soon as they are encountered on the invocation line.
2476 Fri Apr 20 13:47:15 PDT 1990
2479 Thu Apr 19 09:54:28 PDT 1990
2480 Add 'reset' command.
2482 Wed Apr 18 09:48:07 PDT 1990
2483 After opening remote tty, wait for 1 second to go by without input
2484 from it before trying to talk to NINDY (fixes problems with the
2485 Heurikon HK80/V960E).
2487 Mon Apr 4 16:33:05 PDT 1990
2488 Some output was not being suppressed in 'batch' mode.
2490 Thu Mar 22 15:31:11 PST 1990
2491 Ask user if old symbol table should be deleted when new file is
2494 Allow user to run a program downloaded before gdb960 was brought up.
2496 Correct "exec-file" help message for i80960 context.
2498 Correct bug in calculating user space address: could occasionally
2499 corrupt user program.
2501 Make sure to zero low-order bits in rip's because of bug in 960CA
2502 A-step part: could cause operation faults when "next"ing across
2505 Correct bug that made it impossible to get source line numbers for
2506 code loaded at addresses higher than 0x7fffffff.
2508 Wed Jan 10 12:43:22 PST 1990
2509 Open remote tty for exclusive use.
2511 Fri Jan 5 12:14:42 PST 1990

2513 opcode for sysctl is 0x659
2515 Mon Oct 23 12:03:04 PDT 1989
2516 Use G960BASE and G960BIN environment variables to find 'sx' utility.
2518 Mon Oct 16 14:15:09 PDT 1989
2519 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
2521 Mon Oct 2 15:56:31 PDT 1989
2523 Added 960CA disassembly support.
2525 To simplify maintenance:
2526 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
2528 - eliminated opcode.h: incorporates tables into i960-pinsn.c
2529 - moved 960-specific routines from i960-pinsn.c to i960-md.c
2530 - made disassembly interface identical to that in gdmp960.
2534 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
2536 * target.h: Allow targets to stack. Add target_has_memory,
2537 _registers, etc. Restructure memory access and "info files"
2538 to walk the target stack.
2539 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
2540 target.c: Change tables to match target.h.
2541 * inflow.c (child_mourn_inferior): pop child_ops.
2542 (generic_mourn_inferior): Use new has_stack flag.
2543 * infptrace.c (child_xfer_memory): New memory regime.
2544 * inftarg.c (child_files_info): New "info files" regime.
2545 * remote-eb.c: New memory regime, new info files.
2546 * remote-vx.c: New memory regime, new info files. Now use
2547 separate targets for VxWorks attachment to machine, and
2548 actually running a process under VxWorks, since one has
2549 stack & execution & regs and the other doesn't.
2550 * remote.c: New memory regime, new info files.
2551 * sparc-xdep.c (fetch_core-registers): New memory regime.
2552 * target.c: New routines and support for stacked targets,
2553 new memory regime, new info files regime.
2556 Generalize section handling for an arbitrary number of sections,
2557 including use of the new BFD (binary file) library.
2558 * gdbcore.h: Add struct section_table.
2559 * exec.c (build_section_table): Iterate all sections and
2560 record what gdb needs to know about them.
2561 (exec_command): Use it.
2562 (exec_xfer_memory): Use the table.
2563 (exec_files_info): Print the table.
2564 * core.c (core_file_command, core_xfer_memory, core_files_info):
2566 * source.c (find_source_lines): Use bfd_get_mtime.
2567 * dbxread.c: Quick changes to make it compile with new BFD.
2568 * utils.c (error): Avoid using bfd_error in generic routines.
2570 * core.c (core_fetch_registers): Get from the ".regs" section of
2572 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
2574 * inferior.h (attach_flag): Export.
2575 * infcmd.c (run_command): use new target_create_inferior.
2576 * infrun.c (child_create_inferior): Don't return result.
2577 * Makefile.dist (VERSION): 3.91.4.
2579 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
2581 * breakpoint.c (bpstat_num): Handle breakpoints which have
2582 since been deleted, such as temporary breakpoints.
2583 infcmd.c (program_info): ditto.
2585 * core.c (core_file_command): Display the frame where the core
2590 * remote-vx.c (target_command): Merge in target command from
2591 targ-vx.c. A few other cleanups.
2593 * TODO, Projects: Lots more stuff to do...
2595 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
2597 Massive changes to wall off the remote-debugging interface
2598 behind a function vector. The port to handle VxWorks targets
2599 is also part of this.
2601 All files: Replace references to renamed functions,
2602 remove references to remote_debugging, remove references to
2603 have_include_file, have_core_file in favor of target_has_stack,
2604 target_has_memory, etc.
2606 * Modularize the breakpoint interface.
2607 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
2608 a breakpoint instruction.
2609 breakpoint.c: struct breakpoint's shadow_contents now sized as
2611 (insert_breakpoints): Vector to target to install breakpoints.
2612 (remove_breakpoints): Vector to target here too.
2613 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
2614 sparc-tdep.c (single_step): Use new breakpoint interface for
2615 the single-step breakpoints.
2616 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
2617 New file, contains routines to insert and remove breakpoints by
2618 reading out the old contents and later replacing them. This is
2619 how ptrace breakpoints work, and many remote systems as well.
2621 * tm-vxworks68.h: New config file, overrides a few things for
2622 Wind River's preferences.
2624 * target.h: New file, for transfer vector used to talk to the
2625 inferior (child, attached, core, exec, remote, etc). All accesses
2626 to the thing being debugged should come through these vectors.
2627 target.c: New file, routines to handle transfer vector.
2628 (various files): Add transfer vectors XXX_ops for the various
2629 targets and pseudo-targets (core files, etc) we support.
2631 * breakpoint.c (bpstat_stop_status): Further explorations of
2632 watchpoints and why things don't work all the time.
2633 (bpstat_alloc): New fn to allocate a bpstat and chain it.
2635 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
2636 the local gdbinit if it doesn't already have it.
2638 * core.c (core_ops): add and install.
2639 Allow core debugging without exec file.
2641 * dbxread.c (free_and_init_header_files): Merge two fns.
2642 (end_symtab): Free named symbol table when a new version comes in.
2643 (read_dbx_symtab): Relocate all kinds of symbols with base
2644 address. First step toward handling different text, data, bss
2646 (add_file_addr_command): Renamed add_file_command.
2647 (add_file_command): Vector to remote handler.
2648 Add "load" as an alias for "add-file" command.
2650 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
2651 non-returning functions.
2653 * exec.c: Add exec_ops, and push it as a target when an exec
2656 * infcmd.c (run_command): Pass executable file name and arg list
2657 separately when starting an inferior. Permit "run" when no exec
2658 file is specified, for VxWorks.
2659 (detach_command): Move to child_detach in inftarg.c.
2661 * inftarg.c: New file. Unix-child-specific routines, and the
2662 child_ops structure.
2664 * inferior.h (registers): Export "registers" as the way for
2665 target dependent register handlers to find gdb's local copy of
2666 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
2667 since it is now used by places that want wait_for_inferior to
2668 handle the grunge but want to see every trap from the inferior.
2670 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
2671 Eliminate remote_debugging hooks in terminal handling.
2673 * infrun.c: Replace start_inferior with child_create_inferior.
2674 Move all the hair of Unix shells and ptrace idiosyncracies into
2675 child_create_inferior, so remote handlers don't have to deal.
2676 Remove running_in_shell. Rename stop_after_attach to
2677 stop_soon_quietly, and use it in a few other places where we want
2678 to just call wait_for_inferior and get control back on the first
2679 trap. trap_expected now never takes a value > 1.
2680 (init_wait_for_inferior): Initialize static vars when a new
2683 main.c (gdbinit): Add new hook for .gdbinit file name, let
2684 it be overridden by config files as GDBINIT_FILENAME.
2685 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
2686 Both of these are used for VxWorks gdb.
2688 mcheck.c: rename include file "gmalloc.c" to avoid problems
2689 with system include file "malloc.c".
2691 param-no-tm.h: New include file, same as param.h but does not
2692 include the default "tm.h" file. This is used in files where
2693 the target is known, e.g. remote-eb.c or sparc-xdep.c.
2695 param.h: Now just a shell that includes tm.h and param-no-tm.h.
2697 remote-vx.c: New file, VxWorks remote debugging support. Uses
2698 RPC routines that are shared with the target system, in directory
2701 remote.c: Vectorize remote interface.
2703 source.c: Globalize source_path, and make an alias "l" for "list"
2704 since we now have the "load" command.
2706 sparc-xdep.c: Use new param-no-tm.h.
2708 symmisc.c (free_named_symtab): Add new function from Wind River.
2709 However, ifdef it out for now while we think about what it should
2712 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
2714 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
2715 non-Unix-children handle this with their own code in the target
2718 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
2719 source and target lists. Add vx-share to default list of include
2720 directories. Add new files to src and target lists: mem-break,
2721 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
2722 ${srcdir} versions of munch and createtags are used.
2724 * valops.c (find_function_addr): Split out of call_function.
2725 (call_function_by_hand): Rename call_function; this function
2726 calls functions in the target by laboriously patching the target
2727 word-by-word with the right stack, args, regs, etc.
2730 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
2732 Handle AMD 29000 a bit better.
2734 * remote-eb.c (readchar): Mask received char log to make it readable.
2735 (remote_start): Pass arguments down to executing program.
2736 Make startaddr unsigned.
2737 infrun.c (start_inferior): Accept args, pass them to
2739 infcmd.c (run_command): Pass args down to start_inferior.
2741 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
2742 the target object file format.
2743 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
2745 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
2746 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
2748 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
2750 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
2751 * TODO: We did a few things, we have more to do though.

2754 * inflow.c (inferior_died): Clear deferred stores.
2756 * Debug problems with dummy frames and calls to the inferior.
2757 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
2758 * sparc-tdep.c (do_restore_insn): Simplify.
2759 (sparc_frame_find_saved_regs): Simplify and fix what we find.
2760 (sparc_push_dummy_frame): Simplify and fix what we push.
2761 (sparc_pop_frame): Slightly more hair here, deciding whether
2762 we are restoring a saved PC or returning to a return address in %i7.
2763 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
2765 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
2766 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
2767 * obstack.h (chunkfun): ditto.
2768 * defs.h (xmalloc, xrealloc): ditto
2770 * utils.c (quit): Grab the terminal from the child if necessary.
2772 * inflow.c (term_status_command): Rename to term_info, change
2775 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
2776 (is_delayed_branch): Speed up.
2777 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
2778 Still missing some float ops, and needs testing.
2780 * Support for input and output radixes other than base 10
2781 * defs.h (input_radix, output_radix): Declare.
2782 * expread.y (yyparse, parse_number): Handle changes of input
2783 radix, and ambiguous names-or-numbers in radixes >10.
2784 * printcmd.c (print_scalar_formatted): Print formatted hex
2785 numbers in varying column widths.
2786 * valprint.c (val_print): Use output_format to print scalar ints.
2787 (set_input_radix, set_output_radix, set_radix): Create.
2788 (set_output_radix): Set output_format from output_radix.
2789 (_initialize_valprint): add `set radix' but leave the others off.
2791 * main.c (execute_command): Let stupid questions be turned off.
2792 (_initialize_main): Handle "set stupidity", etc.
2794 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
2795 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
2797 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
2799 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
2800 bfd stuff is still screwed up, but with some manual work, it
2803 * breakpoint.c (bpstat_do_actions): Start over if a command
2804 proceeds the inferior, since the inferior will have stopped and
2805 will need to have its new stop-actions taken care of.
2807 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
2808 compiler fits, simplify it.
2810 * gdb.texinfo (directory command): Doc new dir command.
2811 source.c (directory_command): "dir" now puts things on the front
2812 of the path, moves dups up front, and handles multiple names
2813 on the command line, inserting each one in order. It also
2814 blows away cached line and full_filename info.
2816 * stack.c (backtrace_command): Skip "more stack frames follow"
2819 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
2820 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
2821 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
2822 The only odd one was Gould NP1, which had defined vprintf to
2825 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
2826 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
2827 variable, inspect_it.
2828 valprint.c (print_string, val_print): Use the global inspect_it
2829 to indicate whether to print in Epoch style or normal style.
2831 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
2833 * printcmd.c (call_command): add an alias for the "print" command
2834 which runs expressions and doesn't print the result if void.
2835 (print_command_1): implement it.
2837 * command.c: Remove #if 0'd code. Initialize all the fields
2838 in add_cmd (). Rename do_nothing_command to
2839 not_just_help_class_command, and make it externally visible.
2840 command.h: add user_commands to struct.
2841 * main.c (define_command): Don't overload c->function with a char
2842 string as well as a function pointer.
2844 * eval.c (evaluate_subexp): Reinstall tiemann changes to
2845 calling convention of value_struct_elt () that got dropped in
2848 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
2849 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
2851 * tm-sparc.h (POP_FRAME): replace some constants with defines.
2853 * sparc-xdep.c (store_inferior_registers): defer stores to regs
2854 until a good time (e.g. when we are about to run the child),
2855 saving ptrace calls.
2856 * infrun.c (proceed): handle DO_DEFERRED_STORES.
2857 * tm-sparc.h: define DO_DEFERRED_STORES.
2859 * sparc-xdep.c (store_inferior_registers): when storing float
2860 registers, don't store stack regs too. When storing the SP,
2861 however, DO store the stack regs too. This fixes a bug in which
2862 the dummy frame is not recognized when a call_function finishes,
2863 because its frame pointer (in the stack regs) was never
2865 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
2866 even though we don't know how to read them from an inferior.
2867 valops.c (call_function): Comment about storing SP.
2869 * infrun.c (save_inferior_status): Save away the original bpstat
2870 chain so it can be restored later. Install the copied version for
2871 use by whoever saved the status. It will be blow away by
2872 restore_inferior_status, and the original chain restored. This is
2873 important for people who have pointers into the original.
2875 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
2876 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
2877 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
2880 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
2882 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
2883 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
2884 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
2886 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
2888 * Merge Mike Tiemann's multiple inheritance changes from Sun.
2889 Store the baseclasses in a type struct starting from array element
2890 0 rather than from the unusual array element 1.
2892 dbxread.c: the above.
2893 (virtual_context): Add
2894 Read new debug information about which virtual function table
2895 a virtual function is from, and store it in fn_field.fcontext.
2897 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
2898 TYPE_FN_FIELD_STATIC_P.
2900 symtab.c: the above.
2901 valops.c: the above. Handle pointer casts of object *'s.
2902 (search_struct_method): Add.
2903 (value_struct_elt): First arg is now a pointer to a value, and is
2906 valprint.c: the above.
2907 values.c (value_virtual_fn_field): Add type arg. Handle
2908 offsetting to the proper object when calling virtual fns.
2910 (baseclass_addr): Add valuep arg.
2912 * README: Document the current state of BFD config (missing).
2913 * TODO, ChangeLog, Makefile.dist: Roll version.
2914 * WHATS.NEW: Add summary of changes since 3.5.
2916 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
2918 * dbxread.c (read_struct_type): Clear bit vectors whenever
2920 symtab.c (B_CLRALL): define.
2922 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
2923 using == rather than =. Huh... This fixes the dreaded problem
2924 wherein builtin_type_int becomes TYPE_CODE_FLT.
2926 * core.c (info_files): Show the inferior pid.
2928 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
2929 already knows how to look in the source directory.
2931 * Remove psymtab hair from many places. Remove duplicated code
2932 for searching symbol tables. Hide psymtabs from most places.
2933 Make it fast to get from a psymtab to its symtab.
2935 blockframe.c (blockvector_for_pc): Remove psymtab hair.
2936 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2937 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2938 dbxread.c: export psymtab_to_symtab, make it work if called N times.
2939 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
2940 new symtab completely. New psymtabs get symtab pointer
2941 initialized to zero. Remove MI warning printf.
2942 symtab.h: Comments. Add psymtab to symtab pointer.
2943 (PSYMTAB_TO_SYMTAB): New macro.
2944 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
2945 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
2947 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
2949 (print_frame_info): Avoid special-casing symbols that have not yet
2952 * source.c (open_source_file): Quick path if we have already
2953 located the source file by its full name.
2955 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
2956 find_pc_psymtab. When a name is found in the misc function
2957 vector, search the symbol table for its mangled name, not the
2958 name that the user typed.
2960 * bfd.h: Fix missing comment terminators, make #endifs match.
2962 * valarith.c (value_less): Handle unsigned int comparisons.
2963 Add FIXME about pointer compares, which assume host and target
2964 pointers are the same.
2966 * command.c (do_nothing_command): lint
2967 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
2968 fix comments on debug symbol format for visibility. Actually set
2969 visibility of symbols.
2970 main.c (echo_command): lint; use <readline/history.h>.
2971 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
2972 obstack.h (_obstack_blank): Rearrange pointer math to avoid
2973 pointing past end of allocated memory; saber complains.
2974 obstack.h: Declare the external functions that we use.
2975 valarith.h: use <string.h>
2976 solib.c (solib_add): lint.
2978 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
2980 * main.c (initialize_main): Default info_verbose to off, now that
2981 symbol reading is fast.
2982 (quit_command): Avoid clobbering exec_bfd while quitting.
2984 * Initial BFD (binary file diddling library) merger:
2985 coffread.c: Change AOUTHDR to struct exe_hdr.
2987 core.c: initialize initialized data at compile time.
2988 (core_file_command): Move from coredep.c, convert to bfd.
2989 (xfer_core_file): Convert to bfd.
2990 exec.c (exec_file_command): use bfd routines.
2992 mips-tdep.c: Remove exec_file_command and friends.
2995 * coredep.c: (fetch_core_registers) Convert core_file_command to
2996 fetch_core_registers.
2997 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
2999 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3000 (my_bfd_read): More bogosity, which I don't think we call.
3001 (program_name): Remove this atrocity asap!
3003 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3006 values.c: allocate_repeat_value was not clearing the
3007 optimized_out field.
3008 (value_static_field): minor stylistic fix (wrong macro was used).
3009 valops.c (value_struct_elt_for_address): didn't work for C++
3012 * signame.c (_initialize_signame): Initialize signal names once.
3014 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3015 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3016 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3018 * remote-eb.c: Support user-settable baud rates on the serial port.
3020 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3022 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3024 * tconfig/sun3os4: Remove warning about native assembler,
3025 since it also occurs in the xconfig file.
3027 * findvar.c (registers): Allocate some slop after `registers'
3028 to prevent stray accesses from trashing the next variable.
3030 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3031 on the sun-3, by changing the #ifdef from `sun3' (which is not
3032 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3033 vars, which happened to follow `registers' in the executable.
3035 * readline/history.c (history_search): Heed gcc-2's advice
3036 and parenthesize && inside ||).
3038 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3039 tm-29k.c: Insert FSF copyright headers.
3041 * remote-eb.c: Better comments.
3043 * Makefile.dist: Update to 3.91.6.
3044 * TODO: note PREPARE_TO_STORE problem.
3046 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3048 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3050 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3052 * infrun.c (wait_for_inferior, at end): Don't set up
3053 prev_* if the inferior no longer exists.
3055 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3056 CANNOT_EXECUTE_STACK.
3057 valops.c (call_function): Use it.
3059 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3061 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3062 infrun.c (wait_for_inferior, 2 places): Use it.
3064 * values.c (value_being_returned): Only use
3065 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3067 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3068 right thing for remote-eb.c.
3070 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3071 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3073 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3074 (FRAME_FIND_SAVED_REGS).
3076 * findvar.c ({fetch,store}_registers): Check for
3077 REMOTE_{FETCH_STORE}_REGISTER macro.
3079 * findvar.c (get_saved_register): Add argument lval and
3080 change meaning of argument addr.
3081 findvar.c: Change calls to get_saved_register to reflect
3082 new calling convention.
3083 valops.c (value_assign): Use get_saved_register instead of
3084 find_saved_register.
3086 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3088 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3089 an (uninitialized) pointer to one. Use "&" when passing it
3092 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3094 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3097 * coffread.c (symbol_file_command): Put semicolon after
3099 Put safe_to_init_tdesc_context in #if defined (TDESC).
3100 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3101 coffread.c: #include <sys/stat.h>.
3102 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3103 Add missing ')' in check for "lc%" and friends. Remove
3105 Declare read_one_sym() at top of file.
3106 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3107 MC68WRMAGIC can have the same value without causing a duplicate
3110 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3112 * Allow a Makefile to be built without building the
3113 tm and xm file links that screw up builds in subdirectories.
3114 This is done with `config.gdb none', then you can do things
3115 like `make gdb.tar.Z'.
3116 * tconfig/none: Config file for no target system
3117 * xconfig/none: Config file for no host system
3118 * config.gdb: If no TM or XM files are called out by the
3119 host or target file, don't make links for them.
3121 * cplus-dem.c: Add documentation.
3123 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3124 simple error, so the user's gdb doesn't crash due to some object
3125 file problem (e.g. somebody is rebuilding the file out from under
3128 * printcmd.c (print_address_symbolic): demangle the symbol.
3130 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3131 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3132 (alldeps.mak): sort and uniq all results from this; duplicates
3133 hose gdb.tar.Z link building. Remove RCS files from
3134 tconfig and xconfig. Add config files for sun386. Add
3135 a few odd files to OTHERS and HFILES.
3137 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3139 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3140 Roll version number to 3.91.5. Make lint work in bindir.
3142 * README: Document cross-debugging and new file structure.
3144 * blockframe.c: Lint. Include "value.h" to declare read_register.
3145 (find_pc_partial_function): remove duplicate line.
3147 * command.h: Lint. Declare error_no_arg and dont_repeat.
3149 * tm-news.h: Remove inadvertently duplicated stuff.
3151 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3152 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3154 * config.gdb: Allow `config.gdb host target' form. Clean
3155 up previous change that printed bogus messages when you just said
3158 * core.c: #include "command.h" for lint.
3161 * main.c: Remove some casts of enums. Lint.
3168 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3170 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3171 read it from memory. This will allow us to save ptrace calls
3172 eventually. Changed caller single_step too.
3174 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3175 that we aren't going to use, saving many ptrace calls, especially
3176 when watchpointing or single stepping. Use some #define's for
3178 (store_inferior_registers): Ditto.
3179 (core_file_command): Use some #define's for constants.
3181 * tm-sparc.h: Add #define's for some register numbers, so we
3182 can eliminate the use of random constants in sparc-xdep.c.
3184 * stack.c (frame_command, print_frame_info, up_command,
3185 down_command) Remove frame_changed, since it
3186 causes a bug and doesn't seem to do anything useful. In some
3187 places it was used as a flag, in others as a stack level (?).
3189 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3190 default is to use the portable (vprintf) version rather than the
3192 * xm-news.h (MISSING_VPRINTF): Add.
3194 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3196 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3198 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3199 about linking debugged programs -Bstatic in the sun?os4 config
3200 files in tconfig and xconfig subdirectories.
3202 * main.c (main): Remove unreached exit(0) now that we exit
3205 * Create TODO file for online bug list. There are too many
3206 "little" bugs to keep track of on paper.
3208 * Change Projects file to refer to bug-gdb@cygnus.com
3209 rather than kingdon@ai.
3211 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3213 * Makefile.dist (VERSION): 3.91.4 now.
3215 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3216 (condense_misc_bunches): Add sanity check that misc_count is
3217 the same as the number of symbols in the bunch.
3219 * coffread.c: rename init_misc_bunches. Pass an argument
3220 to condense_misc_bunches (a zero).
3222 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3223 every time we are called; don't rely on our caller to do it.
3224 (add_file): Remove call to init_misc_bunches.
3226 * mipsread.c: Only warn, don't error, if unknown symbol types.
3227 This keeps an old gdb from falling on its face if it sees newly
3228 extended symbol info. Rename init_misc_bunches.
3230 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3232 * Merge in changes from Per Bothner for DECstations and other
3233 MIPS stuff. The rest is Bothner speaking:
3235 The next message is a merger of Alessando Forin's mips port with
3236 mine. I've tried to use my good if biased judgment to get
3237 the best of both. It *does* need testing.
3239 Some of the changes are general, *not* mips-specific.
3242 Didn't believe in little-endian bit order.
3243 There are still inconsistencies about whether flags
3244 like BITS_BIG_ENDIAN are integer (#if ...) or
3245 boolean (#ifdef ...). I tried to paper over them.
3247 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3248 Moved some misc_function code that was common to
3249 {dbx,coff,mips}read.c to symtab.c.
3250 In the process, I think I cleaned things up a bit.
3251 At the same time, moved obsavestring and obconcat to symtab.c.
3254 Removed obsolete condense_addl_misc_bunches (use
3255 condense_misc_bunches(1) instead).
3258 Needed to include <sys/dir>, at least on DECstations.
3260 valops.c, mips-tdep.c, tm-mips.h:
3261 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3262 conventions (when STACK_ALIGN is insufficient).
3263 Needed on mips, where doubles need 8-byte alignment,
3264 but ints only need 4.
3267 Removed cruft that was not being used.
3268 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3271 Print $ before register-names (I think that makes things a little
3273 Never print two instructions, even if one delays.
3274 Removed hex-disassemble set_cmd. (This is not mips-specific,
3275 so I think the argument is whether it is generally worthwhile or not.
3276 I'm inclined to think not, given how easy it is to
3277 convert between radixes in gdb.)
3280 This is basically Alessando's code.
3281 It doesn't use obstacks; I changed it to use obstacks
3282 in a few minor places where using malloc causes a
3283 memory leak. (Probably, more places could/should be changed.)
3284 I added record_misc_function where it was missing.
3285 In symbol_file_command and add_file_command, I tried
3286 to make the code consistent with more recent versions.
3287 Minor sylistic changes in parse_procedure.
3288 Make a .gdbinfo. psuedo-symbol point back to the real
3289 procedure symbol (using the isym field).
3292 This is basically from my port, but with a lot of details
3293 and a number of routines merged in from Alessando's version.
3294 I basically used my code "raw" backtrace (use heuristics
3295 from the actual code, rather than symbol table info) - though
3296 the idea is Alessandro's. I feel my code is a little cleaner
3297 here, particularly in being a little more flexible, such as being
3298 able to handle gcc-produced code (which it now can).
3299 It also doesn't do frame caching (which is not useful
3300 more recent gdb versions).
3301 I also used my code for push_/pop_dummy, more or less.
3302 I tried to incorporate AF's code for testing sigtramp
3303 while backtracing; I probably got it wrong.
3304 Added mips_print_register, which tries to scrunch as much
3305 information as possible on a screen...
3306 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3307 under mips-pinsn.c), I don't see anything mips-specific here,
3308 and I don't see it being all that useful anyway.
3311 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3312 Use more register names (rather than hard-cases numbers).
3314 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3316 * Hack up 3.90.11 changes:
3318 * Makefile.dist (depend): parameterize $(GCC).
3319 Add solib.c and solib.o.
3320 (readline): Fix vpath for both absolute or relative SRCDIR.
3322 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3323 Also, let the part I didn't understand at least compile so
3324 I can test the rest. FIXME.
3326 * dbxread.c: Fix thinko using strcmp.
3327 (init_psymbol_list): declare static.
3328 (partial_symbol_file_open): Comment cleanups better, avoid
3329 cleaning up the string table since the caller will do that.
3330 Move the stat for mod time into symbol_file_command, temporarily.
3331 (There should be a mod time for each symbol file, eventually,
3332 to control its rereading. FIXME.)
3334 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3335 SunOS, which gives error for shared libs otherwise. (From
3336 Schaefer, probably FIXME needs work for portability.)
3338 * solib.c: Move #include "param.h" to work.
3339 Lowercase all the Uppercase Letters In the Messages.
3340 (find_solib): Clean up inferior_so_name for debug printouts.
3341 Allow no argument, to mean all shared libraries.
3343 * symmisc.c: include param.h to get CLEAR_SOLIB.
3345 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3347 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
3348 to 3.90.11. ChangeLog entries below are from this.
3350 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3354 * Makefile.dist (HFILES): Add tm-sunos.h.
3356 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3360 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
3362 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
3364 * sparc-opcode.h Added single-operand version of rett.
3366 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3368 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
3369 Put parens around gcc_p in expansion.
3371 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3373 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
3375 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3377 * Changes for Sun shared libraries:
3378 blockframe.c (find_pc_partial_function): If a non-text symbol
3379 is found, set *address = pc - FUNCTION_START_OFFSET.
3380 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
3381 Disable breakpoints instead of giving an error.
3382 source.c (select_source_symtab): Initialize cs_pst.
3383 symmisc.c: Call CLEAR_SOLIB if defined.
3384 symtab.h: Make text{low,high} CORE_ADDR not int.
3385 (psymtab): New field addr.
3387 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
3388 (record_misc_function): Give correct type for N_DATA symbols.
3389 (condense_misc_bunches): do "misc_function_count = j" regardless
3391 Take code which is shared between symbol_file_command and
3392 add_file_command and put it into partial_symbol_file_{open,read}.
3393 Split add_file_command into add_file_command and add_file.
3394 Make psymtab_to_symtab read in the string table if the file
3396 Two new parameters to read_dbx_symtab and start_psymtab.
3397 tm-sunos.h: New file.
3399 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3401 * infcmd.c: Change cont_command to continue_command and "cont"
3404 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3406 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
3408 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
3410 * values.c (USE_STRUCT_CONVENTION): Check for structures of
3411 size 1,2,4,8 rather than size < 8.
3413 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
3414 as necessary, not just once.
3416 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3418 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3420 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3422 * tm-news.h: Add CALL_DUMMY_*.
3424 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
3426 * config.gdb: In list_host, list_target, use ${i}, not $i.
3428 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3430 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
3432 * sparc-opcode.h: Change all store floating-point state register
3433 instructions to have the right match & lose fields.
3435 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3437 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
3439 config.gdb: If srcdir != ., create readline directory and
3440 copy a makefile into it.
3442 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
3443 consistency with POSIX.
3445 * breakpoint.c (bpstat_stop_status): Disable watchpoint
3446 when we exit its exp_valid_block.
3448 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
3450 * Makefile.dist: Bump version to 3.91.3.
3452 * Clean up handling of breakpoint commands (somewhat).
3453 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3455 inferior.h: Add breakpoint_proceeded to inferior status struct
3456 and globals; save it and restore it.
3457 (clear_breakpoint_commands): Cleanup, remove old #define.
3459 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3460 (save_inferior_status, restore_inferior_status): handle it also.
3461 (proceed): Remove earlier code that set breakpoint_proceeded.
3462 It is now set only in clear_proceed_status.
3463 (clear_proceed_status): Cleanup, use bpstat_clear rather
3464 than clear_breakpoint_commands. No callers need the stop_bpstat
3465 between clear_proceed_status and proceed.
3467 infcmd.c: Add breakpoint_proceeded definition and comment.
3468 (cont_command, jump_command, signal_command): Move call to
3469 clear_proceed_status right next to call to proceed.
3471 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3472 caller's argument while running down the chain of breakpoints.
3473 Use new variable "breakpoint_proceeded" to determine when
3474 a command that it executes moves the inferior past the
3476 (bpstat_clear): Handle NULL argument.
3477 (bpstat_clear_actions): Avoid useless call to
3478 breakpoint_auto_delete.
3479 (delete_breakpoint): Clean up bpstat's that are pointing to
3480 the deleted breakpoint from the stop_bpstat chain.
3481 (breakpoint_auto_delete): Simplify.
3483 * Clean up handling of EOF, error on stdin, etc. This was
3484 prompted by a network problem that caused gdb to go into an
3485 infinite loop filling up its malloc'd memory.
3487 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
3488 not clear_breakpoints_commands, which is now gone.
3489 (main): If command_loop returns (e.g. from EOF on stdin), do
3490 a quit_command (looping back to command_loop if quit_command
3491 doesn't really quit).
3492 (command_loop): check result from command_line_input and
3493 exit if it returns NULL, rather than passing the NULL to
3495 (gdb_readline): Free malloc'd result space before returning
3498 * utils.c (query): Handle C-d to mean "yes", just as if the
3499 input was not a terminal. Also avoid infinite loop if EOF
3500 occurs in mid-input-line before newline. This allows
3501 query to be used at EOF on stdin with reasonable results.
3503 * infrun.c (proceed): Set breakpoint_proceeded.
3505 * values.c (value_as_long): Avoid infinite recursion for enums.
3506 (_initialize_values): Fix typo in help msg (kingdon).
3508 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
3509 RL_LIB for linking. This allows -lreadline for linking
3510 and nothing for dependencies, once readline is a real library.
3512 * config.gdb: Jim Kingdon: give useful error message if the
3513 host or target type is not recognized.
3515 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
3516 it just defines it. Dumb, but deal with it.
3518 * Jim Kingdon suggests:
3519 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
3521 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
3523 * Makefile.dist (VERSION): Bump version # to 3.91.2.
3525 * Clean up Bothner's changes.
3527 * blockframe.c (clear_pc_function_cache): New function.
3528 * blockframe.c: remake cache_pc_function_* static.
3529 * dbxread.c (symbol_file_command): remove references to
3530 cache_pc_function_* variables.
3531 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
3532 * printcmd.c: Avoid kludging a global variable (addressprint)
3533 to avoid printing the address of a string twice. Instead,
3534 pass the format letter 's' down low enough that it can be seen
3535 to avoid this problem.
3536 (print_formatted): Pass format arg to value_print.
3537 (restore_addressprint): Remove function.
3538 (do_examine): Avoid hacking addressprint, cleanups and such.
3539 (print_frame_args): Add a comment to a Bothner change.
3540 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
3541 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
3542 to wipe out the values cached in blockframe.c.
3543 * symtab.c (find_method): Add comment saying how big you must
3544 allocate to be "big enough". Per being terse again.
3545 * valprint.c (val_print): Handle format letter "s" to print
3546 strings without addresses. Add comment to vtbl printing code
3547 which casts with wild abandon. Rearrange reference-printing
3549 @0xaddr: value (print w/addressprint)
3550 value (print w/~addressprint)
3551 @0xaddr (parameter lists w/addressprint)
3552 or nothing (parameter lists w/o addressprint)
3554 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
3556 * Merge more changes from Per Bothner:
3558 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
3559 annoying) that I tried to improve it. Here are my suggestions.
3561 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
3564 Do automatic de-reference when taking the address of a reference.
3566 Don't deref_ref when printing parameter lists.
3568 More attempts at treating refernences properly.
3570 In val_print, if deref_ref==0, don't print dangling " = ".
3572 Add COERCE_REF macro, which de-references an REF.
3574 * Merge changes from Per Bothner:
3576 * Fixed (Sony news)-specific configuration problems.
3577 * Fixed other problems with using vanilla pcc and libc (enum problems;
3578 assumption that vsprintf exists).
3579 * Some major speed-ups (finc_pc_partial_function now caches a match;
3580 parsing avoids duplicate symbol_lookup calls).
3581 * Changed handling of baseclasses (no longer use baseclasses field
3582 of struct type, use the first n_baseclasses fields instead).
3583 * Various minor changes/fixes, most C++-related.
3586 Cache the most previous match from find_pc_partial_function.
3587 (Save both low and high ends of matching function's pc range.)
3588 This speeds up the loop of infrun.c:wait_for_inferior quite
3589 a bit, and makes step/next commands much zippier.
3591 Added an enum->int cast (otherwise, some compilers barf).
3593 No longer set baseclass offset to 0, since multiple
3594 inheritance now mostly works.
3595 Added a number of casts, to shut up compiler warnings
3596 (after stabs where made enums, not ints).
3597 When discarding a symbol table (in symbol_file_command),
3598 must clear the cache introduced in blockframe.c.
3599 Don't convert $vtbl_ptr_type to vtbl any more.
3600 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
3601 Mask off sign bit emitted by g++ for virtual table offset.
3602 Set voffset to -1 (not 1) for static member functions.
3604 Changed parsing/lexing of names to avoid doing symbol lookup twice
3605 (once when lexing to determine symbol class, once for real).
3606 Now only call symbol_lookup once. Fields of 'this' win especially big.
3608 Subpress printing addr twice in the case of 'x/s addr'.
3610 lookup_basetype_type is no longer used.
3611 Add find_methods as recursive helper function to decode_line_1.
3612 This allows multiple inheritance to work.
3613 Also, once one or more matches has been found, do not look in
3614 base-classes. (Baseclass methods would be overridden, anyway.)
3616 Removed baseclasses array in struct type.
3617 Instead of using baseclasses[i], use fields[i-1].
3618 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
3619 Changed sign convention of voffset (previous was inconsistent).
3621 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
3623 Used to assume existence of vsprintf. Re-written to not need it
3624 if HAVE_VPRINTF is undefined.
3626 typecmp was too pessimistic. Made it less so.
3628 Don't print space after address.
3629 If vtable points to a misc symbol (with 0 offset), print it,
3630 since that indicates the actual class of the object.
3631 Changed ype_print_derivation_info to use new inheritance
3632 scheme (without baseclasses vector).
3634 In value_primitive_field, fixed some bugs left over from previous set of fixes.
3635 Also, changes needed because TYPE_BASECLASSES were removed.
3637 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
3639 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
3642 If there is no path set, and the symbols don't indicate what directory
3643 a file was compiled in, look in the current directory. But either
3644 a path or a known compilation directory will prevent this.
3647 Three independent bug fixes:
3648 * Remove the #if 0 block that breaks some stuff.
3649 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
3650 adapt gdb to either SunOS 4.0.* or 4.1.
3651 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
3654 Instantiate the class T when looking for methods in it. (Tiemann@sun)
3657 (type_print) Demangle the name being printed.
3658 (type_print_base) Handle botched demangling without coredump (tiemann).
3661 (check_stub_method): Document routine.
3662 (tiemann) fix bug for no-arg functions
3663 Avoid clobbering beyond end of malloc'd storage.
3664 Terminate the argument list properly.
3666 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
3668 * Changes merged by John Gilmore:
3671 In breakpoint_1, use new print_address_symbolic instead
3672 of find_pc_partial_function. (This forces use of assembler-level
3673 addresses, and avoids misleading non-mangled source-level names.)
3675 Generalize ansi argument such that -1 means skip arglist totally.
3676 Removed global variable print_ansi_qualifiers (which made
3677 code non-reentrant), in favor of extra explicit arguments
3678 to internal routines.
3680 Add new helper function print_address_symbolic.
3681 Use find_pc_misc_function instead of find_pc_partial_function
3682 (since we want assembler-level symbols here).
3684 Print unknown function as just "f (...)", not "f (...) (...)".
3685 Use new fputs_demangled explicitly.
3687 Fixed a typing violation (problem: value.h cannot be imported
3688 without renaming many variable in this file).
3689 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
3690 decode_line_1: Moved forward some never-reached code.
3691 Made decode_line_2 skip function prologues correctly.
3693 fputs_filtered should not demangle by default.
3694 Add new fputs_demangled to demangle on demand..
3696 Change value_struct_elt to use value_primitive_field (using recursive
3697 utility function search_struct_field). This allows foo.bar to work
3698 for multiple inheritance (so far only for data fields).
3699 Change check_field in the same way (recursive helper function
3700 to support multiple inheritance).
3701 (Note: there are more of these problems that I haven't fixed.
3702 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
3703 value_of_this: 'this' symbol name is now just "this", note "$this".
3705 Don't print static members.
3706 Avoid printing "members of <type>" if there are none.
3707 Simplified type_print_derivation_info by merging duplicate code.
3708 Remove useless blank lines in type_print_base (ptype command).
3710 Added declaration of new routine value_primitive_field.
3712 Added value_primitive_field which is generalized version of
3713 value_field that can handle multiple inheritance (non-zero offsets etc).
3714 Re-implemented value_field to call value_primitive_field.
3716 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
3718 * infcmd.c -- insert else to avoid 'delete env' coredump when you
3719 delete the whole environment. Karl Berry reported the bug.
3720 * source.c - fix openp to avoid //'s in filenames, which
3721 trigger an Emacs bug causing it to not be able to find files
3722 when running gdb in a window.
3723 * dbxread.c - zap the #if 0 that botches the add-file code.
3724 It seems to work a lot better without all the code commented out.
3726 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
3728 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
3731 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
3733 * Makefile - added a ${CFLAGS} to a couple of entries,
3734 added remote-sa.sparc.c
3735 * added remote.sa-sparc.c, a modification of remote.c
3736 which conducts a dialog directly with the SparcStation prom.
3737 * breakpoint.c, infrun.c, sparcdep.c added
3738 remote_insert_breakpoint(), and remote_remove_breakpoint()
3739 to breakpoint.c instead of directly writing breakpoint instructions.
3740 * sparcdep.c on remote_debugging,there is no need
3741 to remove signle step breakpoint instructions.
3742 * main.c added "-epoch" flag and "int epoch_interface" to main.c
3744 * printcmd.c - epoch interface sends lisp expressions to open up
3745 epoch windows on inspection.
3746 * valprint.c - added arrayprint, and addressprint and made adding
3747 format controls easier
3748 * wait.h added a couple of undef's because we were getting
3749 complaints about WSTOPSIG and WTERMSIG begin redefined.

3779 `check_method_stub', which uses old-style syntax.
3781 * symseg.h (struct fn_field): Remove unneccessary `args' field.
3782 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
3784 * values.c (check_stub_method): New function.

3819 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
3820 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
3821 when printing the type.
3823 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)

3845 step_resume_break_address != NULL, even if another_trap.
3846 If trap_expected and we enter sigtramp, then set up a
3848 If trap_expected is set when we hit the step_resume_break,
