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

73 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as

621 Permit symbols to be superseded when new symbol files have
622 been read in, particularly for VxWorks.
624 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
625 to the main file, as well as to include files. Also, put global
626 functions into the global psymtab, to make "i fun" work.
627 (end_psymtab): Free named symtabs and psymtabs for a file, once a
628 new psymtab for it has been read.
629 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
630 a file, once a new symtab has been read for it.
631 * mipsread.c: FIXME. We need to do the same for MIPS, but it
632 looks harder to determine the top-level block before it's been
633 queued to the psymtab list.
635 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
636 If we have wiped out any old symbol tables, clean up at end of
638 (symbol_file_command): Don't reference symfile_fns if it's zero.
640 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
641 defines for the blocks of a blockvector that contain global and
642 file-static symbols and the first of the smaller scope contours.
643 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
644 decode_line_1, make_symbol_completion_list): Use the above.
645 * coffread.c (end_symtab, patch_opaque_types): Ditto.

651 * symtab.c (list_symbols): Process the first symbol of the
652 static psymbols list.
653 (types_info): Restore this function from its untimely #if 0.
654 It's not perfect, but it is better than nothing.
655 (_initialize_symtab): Restore "info types".
657 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
659 * m68k-stub.c: Remote stub for 680x0's, created from
660 rem-m68k.shar (which is removed).
661 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
662 Remove RCS log stuff now that we use CVS and it blows our diffs.
664 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
666 * symfile.h (free_named_symtabs): Rename from free_named_symtab.

679 Permit symbols to be superseded when new symbol files have
680 been read in, particularly for VxWorks.
682 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
683 to the main file, as well as to include files. Also, put global
684 functions into the global psymtab, to make "i fun" work.
685 (end_psymtab): Free named symtabs and psymtabs for a file, once a
686 new psymtab for it has been read.
687 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
688 a file, once a new symtab has been read for it.
689 * mipsread.c: FIXME. We need to do the same for MIPS, but it
690 looks harder to determine the top-level block before it's been
691 queued to the psymtab list.
693 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
694 If we have wiped out any old symbol tables, clean up at end of
696 (symbol_file_command): Don't reference symfile_fns if it's zero.
698 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
699 defines for the blocks of a blockvector that contain global and
700 file-static symbols and the first of the smaller scope contours.
701 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
702 decode_line_1, make_symbol_completion_list): Use the above.
703 * coffread.c (end_symtab, patch_opaque_types): Ditto.

715 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
717 * m68k-stub.c: Remote stub for 680x0's, created from
718 rem-m68k.shar (which is removed).
719 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
720 Remove RCS log stuff now that we use CVS and it blows our diffs.
722 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
724 * symmisc.c (free_named_symtab): Make it work, in its current
725 kludgy fashion. Change result to indicate if we blew away bkpts.
726 * dbxread.c (end_symtab): Accumulate result from
727 free_named_symtab and print warning if we blew user's state.
728 * symfile.h: free_named_symtab now returns an int.
730 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
732 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
733 is the first symbol read, even if not mainline.
734 (dbx_psymtab_to_symtab): symfile might be zero, cope.
735 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
736 (set_section_command): New command ("section xxx yyy" -- should
737 be renamed to "set section xxx yyy" FIXME) which sets the
738 base address of a section of the exec file, overriding the
739 virtual address that BFD reports.
741 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
743 * exec.c: Add add_syms_addr_command to exec_ops, so you can
744 load symbols at any address while examining an exec file.
746 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
748 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
749 for printing the float info is host-dependent, not
750 target-dependent. FIXME.
751 * i386-pinsn.c: Move #includes to top, remove useless ones.
752 * i386-tdep.c: Don't bother including <.../reg.h> since we
753 don't use it (and it doesn't exist on host systems).
755 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
756 Convert negative numbers properly.
757 (ieee_test): Make numbers really random; fix format arg.
759 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
760 * core.c (core_detach): Unpush core_ops, which might not be on
761 top. We used to just pop the top, which broke things. Don't
762 need dont_repeat() any more.
763 (core_file_command): Psst! Don't repeat it.
764 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
765 * expprint.c (print_subexp): Avoid switch fallthru on
766 BINOP_ASSIGN_MODIFY, so we can print += and such.
768 * inflow.c (kill_command): After killing inferior, print our
769 current frame in the core file, if we have one.
770 (generic_mourn_inferior): When inferior dies, either select
771 the current frame (in the new target, e.g. core file), or
772 set both the current and selected frames to NULL.
774 Changes from Peter Schauer.
776 * infptrace.c: Avoid <sys/ptrace.h> on USG.
778 * Make all file names fit in 14 characters (sigh and damn!):
779 mv hp300hpux-xdep.c hp300ux-xdep.c
780 mv symmetry-xdep.c symm-xdep.c
781 mv symmetry-tdep.c symm-tdep.c
782 mv convex-opcode.h convx-opcode.h
783 mv tm-vxworks960.h tm-vx960.h
784 mv tm-vxworks68.h tm-vx68.h
785 mv Makefile.srcdir Makefile.sdir
786 mv gdb-int.texinfo gdbint.texinfo
787 mv remote-sa.m68k.shar rem-m68k.shar
788 mv remote-multi.shar rem-multi.shar
789 * Makefile.dist, README, config.gdb, convex-pinsn.c,
790 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
791 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
794 * command.c (user_info_1, user_info): New command for listing
795 the user-defined commands.
797 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
799 * dbxread.c (really_free_pendings): Clear file_symbols
800 and global_symbols after freeing them; otherwise, running
801 this function twice (if it appears twice on the cleanup
802 chain), we try to free things twice.
804 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
805 based on text_addr (the address of text in core), not on addr (the
806 offset between text in the .o file and in core). This change
807 is from Peter Schauer.
809 * main.c: Define ALL_CLEANUPS as a cast of zero.
810 (return_to_top_level): Use it.
811 (main): Do all cleanups after each command run as part
812 of the gdb startup sequence. Also do all cleanups before
813 entering the command loop, and every time we exit the command
814 loop and reenter. Before, the cleanups from the startup sequence
815 were being left undone until the first error!
816 (command_loop): Rename do_nothing cleanup to command_loop_marker
817 so we can see it easily when examining the cleanup chain.
818 (init_signals): Add another do_nothing for signal handling.
819 (quit_command): Only try to kill target if it has execution.
820 Problems in the target stack got us into a state where
821 inferior_pid was nonzero but none of the targets had execution.
822 In this state you couldn't exit gdb.
824 * dbxread.c: Two changes from Peter Schauer.
825 (echo_command): Fflush output after an echo command.
826 (show_history): Pass all args to cmd_show_list.
828 * utils.c (init_malloc): Call mtrace to turn on tracing
829 if the environment variable MALLOC_TRACE is set to a file name.
830 * mtrace.c: Add source file which provides a log of every malloc,
831 free, and realloc to a trace file.
832 * mtrace.awk: Add source file which analyzes the trace file.
833 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
834 (VERSION): Roll to 3.94.3.
836 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
837 (check_duplicates): Don't bother with watchpoints.
838 (set_raw_breakpoint): Comment about danger of this routine.
839 (watch_command): Parse and eval all args before calling
842 * solib.c (find_solib): Avoid error in referencing memory to
843 see if any more shared libraries have been added. This is
844 particularly useful if the target has terminated. Bug reported
847 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
848 in bringing up 3.94.2 on the Sun-3.
850 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
851 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
852 expression (in scope) before reenabling watchpoint.
853 * signame.c (init_sigs): Add missing declaration of i, fix
854 sys_siglist declaration.
855 * source.c (list_command): Fixed range computation to use
857 * stack.c (backtrace_command): Do not allow command if target has
858 no stack, print informative error message.
859 * target.c (target_command): Do not write into command line
860 because this fails if the target command is used in a user defined
861 command. [This change was enhanced by gnu to support any-
862 unique-prefix matching on target names.]
863 * valops.c (value_struct_elt): Avoid infinite loop on an
864 erroneous attempt to print the member of function (try p main.p).
866 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
868 * expread.y (name_no_typename): Avoid reduce/reduce errors
869 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
870 Since the GDB parser really doesn't use name_no_typename in a
871 name-only context, the parser can't tell the diff between
872 names and numbers here. Avoid allowing a name_no_typename
873 to be a NAME_OR_*INT to resolve the conflict.
875 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
877 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
879 * valprint.c (val_print_fields): bitfield printing didn't handle
880 byte order. Indirect through a few more fns to cope.
882 * values.c (modify_field): also cope with byte order.
884 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
886 Cleanup for release 3.94.2:
888 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
889 include files. Roll version to 3.94.2.
891 * coffread.c (init_stringtab): Read length into unsigned char
892 array before swapping; don't assume 32-bit longs.
894 * target.c (target_info): Don't bother with get_sym_file, just use
895 the symfile global variable.
896 * symtab.h, symfile.c (get_sym_file): Delete it.
898 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
899 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
900 (read_type): Replace one more error() with complain().
902 * mipsread.c (parse_partial_symbols): Replace printf with complain.
904 * i960-tdep.c: Fix copyright attribution.
906 * config.gdb: Quote all backquotes in doublequotes. You can
907 quote me on that. BSD 4.4 shell found this one.
909 * infptrace.c (throughout): The third argument to ptrace is an
912 * infrun.c (wait_for_inferior): When program has terminated, we
913 have to call target_terminal_ours before we pop that target off
914 the stack (e.g. before a call to target_kill or
915 target_mourn_inferior). This fixes problem where a program
916 terminates, then GDB stops for (tty output) and you have to type
917 "fg" to the shell to resume it. FIXME: This code for what to
918 do after termination really should be in normal_stop instead.
920 * gdbcore.h (read_memory_check): Change declaration; it changed
923 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
924 4.4 prereleases, this avoids a bug in their sgtty compatability
926 * remote.c: Use terminal.h rather than hand-rolling the same.
928 * signame.c, signame.h (psignal): Arg is unsigned, not int.
929 * utils.c (strsave, strstr): Fix arg types.
930 * valprint.c (val_print): lint
932 MIPS symbol table support from Per Bothner:
934 * symfile.c (symtab_fns): Remove initializer table that needs to
935 be hacked for each new symbol file format supported.
936 (add_symtab_fns): New function, chains symbol table
937 handlers into the global list.
938 (symfile_init): Search this list.
939 * symfile.h: Add next pointer, declare add_symtab_fns.
940 * coffread.c (_initialize_coffread): Call add_symtab_fns.
941 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
943 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
944 symbol *). Thus, we no longer need the hack to trash
945 pst->filename. Good, since that hack confused code in symfile.c!
947 (reorder_symtabs, destroy_all_symtabs): Removed static
948 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
949 Instead, the latter now uses a temporary array (stack-allocated
950 from an obstack, and then freed).
952 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
953 haven't been set in the outermost stBlock of a procedure. This was
954 a problem with f77 binaries on Ultrix 4.?.
956 (new_symtab, new_symbol, new_type): Continue changing code to use
957 obstacks more and otherwise conform to dbxread internal style.
958 Made the free_code of symtabs be free_linetable (as in dbxread)
959 instead of free_contents. This implies memory leaks when reading
960 a new symbol table, until the conversion is finished. Did change
961 (struct symbol) and (struct type) to be allocated on the
962 symbol_obstack. Blocks and blockvectors are among the things
965 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
966 tested much, but it solved one problem (reported by Meissner), and
967 cleans up some other things. The problem happened when an
968 included file contains actual code (functions) and not just
969 definitions. The mips coff is a little inconvenient there, since
970 it may cause a procedure to be mapped to the wrong psymtab.
972 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
973 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
974 this will need work for the new core paradigm.
976 Opcode patches from the net:
978 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
979 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
980 missing altogether - they are added here. From Bruce Bauman.
981 * mips-opcode.h: The low mask for C0 instructions was too small.
982 From Garrett Lau. I modified the fix to check the entire 32-bit
985 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
988 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
990 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
992 * dbxread.c (read_type): Pointer subtraction (value_sub in
993 valarith.c) sometimes failed because the types of the
994 pointers being subtracted were not identical.
995 These differed because dbxread.c was allocating pointer types
996 using dbx_alloc_type+smash_to_pointer_type instead of
997 lookup_pointer_type. I failed to find a justification for the
998 former, so I changed it to use the latter. Similarly, I
999 replaced smash_to_function_type by lookup_function_type,
1000 and smash_to_reference_type by lookup_reference_type.
1002 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1003 _initialize_mipsread): corresponding changes.
1005 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1007 * source.c (mod_path): Do tilde_expand on each component of the path,
1008 rather than on the (list of) paths as a whole.
1009 (print_source_lines): Set first_line_listed in addition to
1010 current_source_symtab and current_source_line. If the source was
1011 not findable, after a "dir" command to fix the problem,
1012 a "list" would get the wrong lines.
1014 While I was there... (gnu):
1016 * dbxread.c (read_type): Change error to complaint.
1018 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1020 First attempt at detailed understanding of symbol table memory alloc.
1022 * dbxread.c (dbx_symfile_read): Free our string table if we
1023 aren't the mainline. Free the "info" struct since we're done with
1025 (init_psymbol_list): Free any previously allocated psymbol lists.
1026 (): FIXME: Should realloc-down the psymbol lists when done reading
1027 the main symbol file?
1029 * symmisc.c (free_symtab): Free fullname field too.
1031 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1032 (REGISTER_ADDR): Make result type unsigned int.
1034 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1035 define REGEX must also define REGEX1 (its dependency).
1037 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1039 * tconfig/i960: No longer works, points you at vxworks960 or
1042 * xgdb.c, XGDB-README: Remove file. Users can get the much
1044 * Makefile.dist: Remove all trace of xgdb.
1046 * breakpoint.c (breakpoint_1): Pass demangle arg to
1047 print_address_symbolic.
1048 (clear_breakpoints): Remove unused function.
1049 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1050 (breakpoint_re_set): Use catch_errors to do them all anyway.
1052 * gdb-int.texinfo (Host versus Target): Add section on what is
1053 a "host" feature versus what is a "target" feature.
1055 * infcmd.c (path_command, path_info): Handle the PATH variable
1056 (object search path) as conveniently as the source search path.
1057 * environ.c (set_in_environ): Set some vars in GDB's environment,
1058 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1059 * source.c (mod_path): New function, from guts of
1060 directory_command, modifies a path. Used by path_command.
1061 (directory_command): Call it.
1062 * defs.h (strsave): Declare.
1064 * utils.c (sevenbit_strings): Add new printing option.
1065 (printchar): Use it.
1066 (strsave): Provide this handy helper routine.
1067 (set_width_command): Rename set_screen_width_command.
1068 (_initialize_utils): "set screen-width" => "set width";
1069 "set screen-height" => "set height"; add sevenbit-strings.
1071 * infcmd.c (do_registers_info): Print floating point registers
1072 in raw hex as well as float format, regardless of whether it is
1073 a "virtual" convertible register.
1074 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1075 regs as a double, just in case it's being used that way.
1076 * values.c (unpack_long): Comment on array/function coercion.
1077 (unpack_double): Argument is in target byte order now. For
1078 integer arguments, just call unpack_long and float the result.
1079 * m68k-tdep.c: include defs.h for "const" handling.
1080 * remote-nindy.c: Use ieee-float stuff.
1081 (nindy_fetch_registers): Unpack double regs to host double, then
1083 (nindy_store_registers): Pack extendeds to host double, flip
1084 around by misusing unpack_double, send as target double.
1086 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1087 zero, as when stopped at the first instruction of a process.
1089 * blockframe.c: Fix filename in comment (param.h => tm.h).
1090 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1091 * tm-68k.h: Fix typos.
1093 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1095 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1097 * coredep.c (fetch_core_registers): Pass end-address of register
1098 section to register_addr as expected. Don't call supply_register
1099 if we'd just pass it garbage.
1101 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1103 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1105 * target.c (push_target, target_info): Cast enums to int for < or

1109 even if we can't print it.
1111 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1113 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1115 Clean up IEEE floating point support.
1117 * ieee-float.h: New file.

1122 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1123 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1124 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1125 double_to_ieee_extended.
1126 * i960-tdep.c: Define ext_format_i960.
1127 * m68k-tdep.c: Define ext_format_68881.
1128 * sparc-tdep.c: Define ext_format_sparc, though unused.
1129 * Makefile.dist (HFILES): Add ieee-float.h.
1130 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT

1136 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1137 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1138 * tconfig/nindy960: Remove reference to coffstrip.o.
1140 * Makefile.dist: Roll version number to 3.94.1 (not yet final).

1145 * dbxread.c: Remove static symfile_bfd.
1146 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1148 * inftarg.c (child_detach): Pop the child_ops vector if the
1149 detach is successful.
1150 * remote-nindy.c (nindy_create_inferior): Don't push a new
1151 nindy_ops since nindy uses the same one for execution and memory
1153 * core.c (core_ops): Use child_attach and child_create_inferior
1154 rather than default attach and create_inferior functions.
1156 Handle floating point registers in core files.
1158 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1159 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1160 This version untested since BFD doesn't yet support sun3 core
1162 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1163 conventions. Fix comments and style. This version has not
1164 been compiled yet, since we have no HP inhouse.
1165 * core.c (get_core_registers): Look for two sections, ".reg"
1166 and ".reg2", and pass both to fetch_core_registers sequentially.
1168 Revise directory path yet again.
1170 * source.c (forget_cached_source_info): Not static any more.
1171 (init_source_path): New default source path is "$cdir:$cwd".
1172 (dir_command): Handle variable arguments ($cdir, $cwd).
1173 (source_info): Print "Compilation directory" rather than
1174 "Originally compiled in" to remind people of $cdir.
1175 (openp): If the path contains $cwd, use current directory.
1176 (open_source_file): If compilation directory is known, replace
1177 first $cdir in path with the compilation directory.
1178 (print_source_lines): Even if we can't print the lines, set the
1179 current symtab and line for future commands like "info source" or
1180 "breakpoint". Also, error message now contains the file name,
1181 line number, and file access error message.
1182 (_initialize_source): Fix help text to describe changes.
1183 * main.c (cd_command): Forget cached source info when we chdir.
1184 * utils.c (strstr): Add simple implementation.

1188 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1189 Byte-swap COFF symbol tables if necessary when reading them in.
1190 Use complain() to replace error message in one spot. Needs
1191 corresponding change in bfd/coff-code.h to make some symbol
1192 swapping routines non-static.
1194 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)

1204 declarations of errno.
1206 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1208 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1209 <rpc/rpc.h> and <rpc/types.h>.
1211 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1213 * i960-tdep.c (examine_prologue): Add new argument limit,
1214 which stops the scan at the end of the prologue, or at the PC.
1215 This fixes a problem where it walks down into the code for the
1216 user's statements if that code looks like function prologues.
1217 Mark Fox and I have been bouncing this code back and forth, making
1218 small changes to it. Callers changed to match.
1220 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1222 Cleanup for gdb-3.94 release final:
1224 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1225 the .c files from vx-share and nindy-share, from the various
1226 macros, since they are not found via ALLDEPFILES.
1227 (SFILES): Add tm-i960.h.
1228 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1229 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1231 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1232 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

1236 * am29k-tdep.c: Add contribution line.
1237 (examine_prologue): Cache information about function prologues in
1238 the misc-function-vector to avoid lots of references over the
1239 serial line while examining instructions.
1241 * core.c (core_close): New function made from cleanup_core.
1243 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1244 remote-vx.c, remote.c, target.c, target.h,
1245 Update target_ops vector to add attach, close, and load entries.
1246 Use add_syms_addr_command, not add_file_addr_command, for
1247 add_file. Break out close routine from existing code.
1249 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1250 they are in an obstack.
1251 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1253 (define_symbol): Add symbol type parameter; change callers;
1254 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1255 it to influence the symbol class on the i960.
1256 (define_symbol): Swap LOC_CONST's into target byte order.
1258 * exec.c (exec_close): New function.
1259 (exec_file_command): Call it.
1261 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1262 Fix byte order of frame pointer.
1263 (read_var_value): Result of 0 if var's value can't be found,
1264 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1265 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1266 (locate_var_value): Use read_var_value and use its lazy address
1267 as the location of the var's value. Lint.
1269 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1272 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1273 obsolete Intel versions in favor of vxgdb versions.
1274 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1275 code dealing with byte order of values, which Intel did in host byte
1276 order rather than gdb-4's target byte order.
1277 (i960_frame_chain_valid): Move to nindy-tdep.c.
1278 (examine_prologue, skip_prologue, frame_find_saved_regs,
1279 frame_args_address, leafproc_return, saved_pc_after_call,
1280 pop_frame): Add vxgdb versions from Mark Fox.

1282 to deal with the saved value of G13 (struct return address
1284 (frame_args_address): Modify Mark's version to prefer the
1285 saved value over the current value in the topmost frame.
1286 Cache result in the frame info to avoid performance hair in
1288 (print_fault): Add gdb960 code for printing faults.
1289 (_initialize_i960): Actually call check_host.
1291 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1292 add stub routines. FIXME, these currently just return zero!

1295 (attach_command): Call target_attach, not target_open, now.
1297 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1298 (child_attach): Rename from child_open.
1299 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1300 don't confuse it with a zero step_resume_break_address.
1302 * inftarg.c (child_detach): Eliminate inferior_pid test.
1303 (child_files_info): Clean up message a bit.
1304 (child_ops): Use child_attach, not child_open, to attach.
1306 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1307 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1308 findvar.c to here, since it depends on the contents of the
1309 shadow_contents of breakpoints, but keep if #if 0 since it is
1312 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1315 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1316 (ptype_command, display_command): Eliminate have_inferior_p and
1317 have_core_file_p in favor of target_has_stack or
1318 target_has_execution.
1319 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1320 code for actually finding the values of arguments, though we still
1321 keep track of the maximum stack offset for use in printing unnamed
1322 arguments. Handle missing FRAME_ARGS_ADDRESS.
1324 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1325 (struct nindy_regs): Define registers passed to/from nindy.
1326 (nindy_fetch_registers, nindy_store-registers): Translate between
1327 nindy and GDB formats for the registers.
1328 (dcache_init): Statically allocate the cache, since it was being
1329 allocated by a malloc that was never freed anyway.
1330 (nindy_create_inferior): Error, not core dump, if no exec file.
1331 (nindy_before_main_loop): Use target_load, not target_add_file.
1333 * remote-vx.c (net_load): Specify large timeout for load
1334 requests. Allow user to break out with INTERRUPT.
1335 (net_break): Remove useless code, clean up. Change callers.
1336 (parse-args, skip_white_space, find_white_space): Clean up arg
1337 parsing to cope with quoted strings.
1338 (net_wait, net_quit): Never call error, just return status.
1339 (vx_read_register, vx_write_register): Cleanup status checking.
1340 #ifdef the code based on which CPU we are using (960 or 68k),
1341 FIXME, this should be completely general but it isn't yet.
1342 (vx_xfer_memory, vx_resume): Cleanup status checking.
1343 (vx_run_files_info): Improve message.
1344 (vx_load_command): Renamed from vx_add_file_command. Allow load
1346 (net_ptrace): Remove unused routine.
1347 (vx_wait): Adopt code from vxgdb960 to cope with broken
1348 connections to target machine and prompt to disconnect. Remove
1349 debug printouts. Map some EVENT_'s to SIGnals.
1350 (add_symbol_stub, vx_open): Print names of object files we found,
1351 and "ok" if we read their symbols OK. Clarify output in general.
1352 (vx_attach, vx_detach, vx_kill): Add these commands.
1353 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1354 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1355 "info files" output, and create_inferior, since we already have
1358 * stack.c (frame_info): Replace Frame_unknown with 0.
1359 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1360 (return_command): Pop until the PC matches as well as the FP,
1361 so it works even if the FP is shared with another function,
1362 as in "frameless" or "leaf" procedures.
1364 * symfile.c (load_command): renamed from add_file_target_command.
1365 (add_syms_addr_command): renamed from add_file_addr_command.
1366 (add_syms_command): Stub to call target_add_syms.
1367 (_initialize_symfile): Change command names and descriptions,
1368 add-file => add-syms, and load from alias to its own command.
1370 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1371 maybe_kill_then_create_inferior): Default for attempts to start
1372 a process, if one is already running, is to ask about killing
1373 it and retry if yes.
1374 (upstack_create_inferior): #if-0 it, strata obsolete it.
1375 (push_target, unpush_target, pop_target): to_close() a target
1376 before unstacking it.
1377 (target_info): Renamed from target_files_info.
1378 (_initialize_targets): Rename "i files" as "i target", accessible
1381 * target.h: Improve comments about the target_ vectored routines.
1383 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.

1386 (SKIP_PROLOGUE): No longer a no-op.
1387 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1388 (*_REGNUM): Sort register numbers.
1389 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1390 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1391 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1392 are now 10 byte extendeds, not 8 byte doubles.
1393 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1394 for nindy versus vxworks targets. FIXME, this should possibly go
1395 in the target vector.
1396 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1397 frame_saved_regs and arg pointer with each frame.
1398 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1399 (FRAME_ARGS_ADDRESS): Use cached result.
1400 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1401 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1402 (PRINT_RAMDON_SIGNAL): Call print_fault.
1403 (POP_FRAME): Now works.
1405 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1406 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1407 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1408 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1411 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1412 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1414 * valarith.c (value_subscripted_rvalue): Avoid handling
1415 floats and doubles specially; it gave alignment errors. Lint.
1417 * valops.c (value_of_variable, value_of_this): Error if unknown
1420 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1421 to avoid alignment problems.
1422 (value_print): Handle unknown value address.
1423 (cplus_val_print): Two args are ignored; remove them. Change caller.
1424 (val_print): Use unpack_long rather than pointer-deref.
1427 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1428 to avoid alignment problems.
1429 (value_being_returned): Error if return value unknown.
1430 (set_return_value): Add bogosity warning, FIXME. *
1432 * TODO: A woman's work is never done.
1434 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1435 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1436 Add ieee-float.o to OBS.
1437 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1438 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1439 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1441 Changes to generalize the VxWorks RPC protocol slightly, to handle
1442 i960 as well as 68000.
1444 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1445 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1446 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1447 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1448 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1449 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1450 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1451 so they will move in target byte order rather than network
1452 byte order (happens to be the same).
1454 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1456 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1458 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1461 Add contribution lines to various files, showing where they
1464 * breakpoint.c (break_insn, check_break_insn_size,
1465 read_memory_nobpt): Remove to mem-break.c.
1467 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1470 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1471 entry has bad register number. This change is not
1472 tested in this release, FIXME.
1474 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1477 * value.h: Force value's contents field to be aligned to hold
1478 at least a double or a long long (if supported). This avoids
1479 doing bcopy's in and out of the contents field.
1481 (step_1): Avoid coredump under obscure circumstances when we
1484 * symtab.h (misc_info): Add field to misc function vector for
1485 any kind of cached information the target code desires. AMD
1486 29000 uses this to avoid repeating examine_function_prologue's.
1488 * coffread.c: Lint. Remove static symfile, read_section_header.
1489 core.c (have_core_file_p): Lint: remove.
1490 expprint.c (print_subexp): Lint.
1491 infptrace.c, valops.c, valprint.c: lint.
1493 Roll in changes from vxgdb-5.0.1:
1495 * symtab.h: Comment byte order of each address class. Add
1496 LOC_LOCAL_ARG for frame-relative args (960).
1497 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1498 symtab.c, symmisc.c: ditto.
1500 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1502 * remote.c (remote_resume): Error if resume with a signal.
1504 * symfile.c (prim_record_misc_function): Clear misc_info.
1505 (fill_in_vptr_fieldno): Check stub type of arg.
1507 * valops.c (value_cast): Avoid looking up names of types whose
1508 name we don't know, to prevent coredump. Sun CC produces typedef
1509 rtx and the name of *rtx is zero...
1511 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1513 Roll in changes from final AMD 29000 port (Tiemann).
1515 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
1516 for ../include/a.out.encap.h. This might not work now that BFD
1517 is separately compiled. Instead, BFD support for encap will have
1518 to translate machine type 29k into the right COFF_MAGIC.
1520 * infcmd.c: Remove references to inferior_pid that aren't used
1521 in actual ptrace calls; use target_has_execution, etc.
1522 (have_inferior_p): Remove function.
1523 (program_info): Print target info rather than "process number";
1524 avoid gratuitous messages unless from_tty.
1525 (run_stack_dummy, finish_command): Set proceed_to_finish.
1526 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
1527 main.c: Lint. Lose have_inferior_p().
1528 inferior.h (have_inferior_p): Remove, lint.
1529 (proceed_to_finish): Add flag to ask that all regs be saved
1530 by normal_stop, for the few commands that need it, speeding up
1531 serial I/O. Add comments to stop_registers.
1533 * remote-eb.c: Remove newline from breakpoint message we grep
1534 for. Never time out when running the user program.
1538 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1540 Roll in changes from vxgdb-5.0.1:
1542 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
1543 symbol in its raw form, we are processing an unlinked ".o" file.
1544 See if the target environment has assigned it an address, using
1545 target_lookup_symbol (VxWorks does), and enter it into the symtab
1548 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
1549 68k versions for a simpler version that assumes zero FP at bottom.
1550 Fixes bug of truncated stack reports.
1552 * target.h (target_lookup_symbol): Define this routine's args
1553 and result, finally.
1555 * target.c (nosymbol): Default routine for target_lookup_symbol.
1556 (target_default): Default lookup_symbol and call_function too.
1557 (files_info): Only print has_all_memory warning if a non-dummy
1560 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
1561 vx_convert_from_virtual): If target does not have floating point,
1562 zero register "values", and avoid doing cross-net conversions.
1563 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
1564 (vx_open): Rearrange code that attaches to target and reads
1565 symbols for all loaded modules, to work if some of the modules
1566 are not accessible. Add symbol_stub() and add_symbol_stub()
1567 as callbacks from catch_errors(). Allow connect attempt to be
1568 interrupted painlessly with ^C (FIXME, there are still some bugs
1569 if the interrupt happens during symbol reading.). Print
1570 final message with puts_filtered, since symbol messages are
1575 * main.c (catch_errors): Only print errstring if non-null.
1576 (command_loop): Avoid an ioctl per command to test ISATTY.
1578 * remote-vx.c (net_load): make static; avoid sophomoric msg.
1579 (vx_xfer_memory): Return correct result!
1580 (vx_files_info): Indicate whether target has float or not.
1581 (vx_lookup_symbol): Complain, not error, if target gone.
1582 (vx_open): Print "Connected" msg before disabling immediate-quit.
1583 [FIXME: lookup_symbol and vx_open changes need testing.]
1585 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
1586 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
1587 contributor lines and update copyrights to 1991.
1589 Changes from an attempted H-PUX host port:
1591 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
1592 defines PT_ATTACH and PT_DETACH but not PT_KILL.
1593 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
1594 * remote-vx.c: include <sys/time.h> for HPUX.
1595 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
1596 "core_file_command" routine to BFD regime. May not work yet.
1598 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
1600 * xgdb.c: Replace X10 version with some VJ version.
1601 (FIXME: Its copyright assignment is not on record.)
1602 * xgdb.c: Update include files to X11R4 (Xaw crud).
1603 (xgdb_display_source, create_text_widget): fix call to
1604 get_filename_and_charpos. Rewack source window stuff for X11R4
1605 (gleaned from include files, and "nm's" of binary libraries, since
1606 I had no doc available).
1607 (append_selection, append_selection_word): Disable with FIXME
1608 since R4 changed interface here.
1609 (create_buttons): Add back the old set of buttons.
1610 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
1612 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
1613 Roll VERSION to 3.94 (not yet final though).
1615 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1617 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
1618 obstack_int_grow, obstack_int_grow_fast): Eliminate
1619 cast on left of assignment, which gives MIPS cc fits and is
1622 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
1623 F_ALIAS. Use printf, not fprintf, when not passing a file
1625 (compare_opcodes): Check that identical instructions have
1626 identical opcodes, complain otherwise.
1628 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
1629 was reported by Roland McGrath.
1630 (unimp): Only match if exactly zero instruction. (Roland)
1631 (branches and traps): Generate all variations of these
1632 instructions with macros, based on a single call that defines
1633 each condition name and its binary representation.
1634 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
1636 * valprint.c (val_print_fields): Take, and use, format parameter.
1637 This means that "p/x struct" again prints the elements in the
1638 desired format. Changed callers.
1640 * stack.c (frame_info): Use filtered output, and indicate wrap
1641 points. Remove kludgy formatting designed to avoid line wrap.
1643 * utils.c (wrap_here): If the line is already full (because
1644 we had printed a long indent or long wrapped string), do an
1645 immediate newline-and-indent.
1647 * m68k-pinsn.c (print_insn_arg): Bugfix from
1648 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
1649 instruction is incorrectly disassembled as bkpt #8.
1651 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
1652 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
1653 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
1654 and then will dump core (sometimes). I traced it back to an
1655 uninitialized symfile_name in psymtab_to_symtab.
1656 (const_vol_complaint): Add quotes to message.
1657 (define_symbol): Only believe line number if gcc_compiled.
1658 Avoid allocating symbol if we will not return it.
1660 Add target strata support so that newly established targets go
1661 into their right place in the target stack (e.g. a new exec file
1662 doesn't wipe out the ability to access the running process).
1664 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
1665 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
1666 and initialize it properly in all the targets.
1668 * target.h: Document strata. Change return type of push_target.
1670 * target.c (nomemory): new function for dummy memory access.
1671 (tcomplain): Rename complain, now also used in symfile.c.
1672 (push_target): Push targets within strata. New return value shows
1673 whether new target is on top of stack or not. Always keep dummy
1675 (target_files_info): Ignore dummy target.
1677 * core.c (core_open): Warn user, and skip accessing file, if the
1678 core target is not the topmost target in the stack.
1679 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
1682 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
1683 target_ops, it doesn't belong there since we have no regs there.
1684 Change name of target from machine => memory to clarify.
1686 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
1688 * Freeze version 3.93 for release.
1690 * Makefile.dist: Handle vx-share and nindy-share subdirs
1691 properly when building gdb.tar.Z.
1693 * symtab.c: lint; add no_symtab_msg to consolidate the messages
1694 printed in various places, so I could change just one copy.
1696 * dbxread.c, coffread.c: Change references to bfd->iostream
1697 to cast to FILE *, now that BFD avoids needing types defined
1698 in other header files.
1700 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1702 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
1703 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
1704 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
1705 (actually gcc -Wall).
1707 * dbxread.c: Remove first_global_sym, last_global_sym, since
1708 they are never referenced.
1710 * defs.h (baud_rate): Declare.
1711 main.c: Define it, and add the -b option to set it.
1713 * gdb-int.texinfo: Add text on how to define a new host or target
1714 architecture, prompted by Per Bothner's questions about MIPS
1717 * gdb.texinfo: Document "complaints". Change doc of -q since
1718 gdb no longer prints the copyright and blurb if you specify a file
1719 name to be debugged (just like Emacs). Add doc for Nindy-specific
1720 command line flags for specifying target serial port and such.
1721 Update copyright to 1991.
1723 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
1724 has taken over for us the job of ripping up executable files. The
1725 crud caused Per Bothner's port to not compile.
1727 * infrun.c (normal_stop): Avoid printing "Program exited
1728 normally" if we are in batch mode. This allows a GDB which
1729 executes a program on a target system, to behave like a Unix
1730 command (input from stdin, output to stdout, no extraneous
1733 * main.c (main): Allow additional machine-dependent command line
1734 options to be specified with the ADDITIONAL_OPTIONS,
1735 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
1736 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
1737 processing to occur just before the main loop with
1738 BEFORE_MAIN_LOOP_HOOK.
1739 (main): If a "core file" argument is specified, and it is not a
1740 core file, try it as a process ID to attach.
1741 (symbol_completion_function): Attempt to cope with
1742 "show screen-" TAB, not very successfully. This needs more work,
1744 (batch_file): New function, returns whether we are reading
1745 commands from an interactive tty on stdin, or from somewhere else.
1746 Called by normal_stop since it doesn't get from_tty passed down
1747 to it like many commands do.
1749 * remote-nindy.c: Handle command line options for nindy
1751 (nindy_before_main_loop): Prompt user for tty name if they
1752 don't specify it before getting to the interactive command loop.
1754 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
1755 and -r command line options. Also add hook before main loop
1756 to make it easy to specify a tty.
1758 * TODO: More things to do, one done.
1760 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
1762 * dbxread.c: Make complaint() calls pass pointer, not struct.
1763 Add complaints about badly formatted C++ type information
1764 (const/volatile indicator, and parse errors resulting in
1765 error_type). Fix C++ virtual member fn comment.
1766 (read_struct_type): Avoid bumping pointer if we got a parse
1767 error; this prevents our walking beyond the end of a string.
1768 Terminate loop on null char as well as semicolon.
1769 (process_one_symbol): Fix the LBRAC fix so that it uses the
1770 last previous SLINE, FUN, or SO record's PC address. C++ debug
1771 symbols did not have SLINE records in a useful order compared
1772 to the LBRAC records.
1773 (define_symbol): Handle "catch" records.
1775 * symtab.c (check_stub_type): Added new complain
1776 `stub_noname_complain' and added a consistency check to
1777 keep the debugger from crashing when finishing from an
1778 exception frame. A real fix will be needed later.
1780 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1782 * infcmd.c (attach_command): Make global.
1784 * Makefile.dist (REMOTE_OBS): Make these compile by default,
1785 but make them easy to comment out. Perhaps later they should
1786 be enabled by what CPU you configure for? FIXME.
1787 (VERSION): Roll to 3.93.
1788 (pinsn.o): Remove rule for obsolete file.
1789 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
1791 Run down a problem that manifested by printing the wrong function
1792 name in stack traces of read_ofile_symtab. Turned out that the
1793 problem was the SunOS 4.1.1 (and previous) C compiler outputs
1794 the LBRAC symbol with an address in the *data* segment, which
1795 blew our binary search through the blocks.
1797 * dbxread.c: Use the complain() facility consistently to bitch
1798 about problems in the symbol file we are reading.
1799 (finish_block): Add code to check the nesting of the blocks;
1800 complain and Procrust them to fit if wrong.
1801 (make_blockvector): Check the order of the blocks, complain
1802 [but don't cope] if wrong.
1803 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
1804 symbols to be sure their PC value is greater than the last SLINE
1805 (line number) symbol we've seen, complaining and adopting the
1806 SLINE PC value if wrong.
1808 * symfile.h (struct complaint, complaint_root, complain,
1809 clear_complaints): Add.
1810 * symfile.c (complain, complaint_root, clear_complaints): Add
1811 facility to deal with non-fatal complaints and to regularize their
1813 (symbol_file_add): Clear complaint counters to allow new complaints.
1814 (initialize_symfile): Add 'set complaints' and 'show complaints'.
1816 * dbxread.c (dbx_symfile_read): Remember the address and size
1817 of the string table for the main symbol file, so we won't read it
1819 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
1820 to avoid reading the string table yet again. Lint.
1821 (throughout): Improve filtered output, including word wrap.
1822 (read_range_type): Improve Bothner's fix to handle other types too.
1824 * utils.c: Improve line wrap implementation. Handle unlimited
1825 width by making chars_per_line unsigned.
1826 (puts_filtered): New, easy, function.
1828 * defs.h (puts_filtered): add.
1830 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
1831 call the identical sort_symtab_syms() in symfile.c instead.
1833 * expread.y: Suggest the `file' command rather than `symbol-file'.
1835 * command.h (enum var_types): Add zinteger for seroable
1837 * command.c (do_setshow_command): Handle var_zinteger. Restructure
1838 nested if's into a switch.
1840 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
1841 we did not stop because of a breakpoint (it must have been for
1842 some other reason, like a "stepi"), so don't print anything.
1844 * symtab.c: Include <sys/types.h> all the time. Now that BFD
1845 doesn't include <sys/types.h>, old SunOS's require it for
1848 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
1850 A test port of gdb-3.92.6 to the Sony NEWS.
1853 Don't normally link in remote- or vx stuff.
1854 Some of it doesn't compile, and it wastes space for 99% of the users.
1855 Remove reference to no-longer-used HAVE_VPRINTF.
1856 Fixed BFD_DEP typo to BFD_DIR.
1858 Fix cast in arg to bfd_h_getlong.
1859 Make char *prefix be const.
1860 Fix how certain range types are mapped into builtin unsigned int types.
1862 Remove 2 #includes. They cause errors (on Sony, at least),
1863 and aren't needed (they wern't in earlier versions).
1865 print_address_symbolic should never demangle labels
1866 (since it prints *assembler-level* labels).
1868 [This was superseded by the change to printcmd below.]
1871 Add some "volatile" return types to avoid warnings.
1872 If MISSING_VPRINTF add vprintf function and not just macro
1873 (since vprintf is used in printcmd.c).
1875 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
1876 (The latter isn't grokked by some PCC-based compilers.)
1878 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
1880 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
1881 * nindy-share/coffstrip.c
1882 Added some forward declarations (otherwise, gcc complains
1883 about implicit extern redefined as static).
1885 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1887 Changes inspired by Per Bothner:
1888 * printcmd.c (print_address_symbolic): Take additional parameter
1889 specifying whether to demangle.
1890 (print_address): Pass in asm_demangle to control demangling.
1891 (print_address_demangle): New fn, takes explicit arg to control
1893 * utils.c: Add new vars demangle and asm_demangle, and let them
1895 (fputs_demangled): If !demangle, just print the argument.
1896 (fprint_symbol): If !demangle, just print raw symbol.
1897 * valprint.c (val_print): Call print_address_demangle rather than
1898 print_address, to cause demangling to depend on the global
1899 rather than assembler-level demangling setting.
1900 * WHATS.NEW, gdb.texinfo: Document.
1902 * main.c (show_command): Show all settings if no arg.
1903 (initialize_main): Make "info set" the same as naked "show".
1904 * command.c (cmd_show_list): Handle prefix commands in the
1905 list, and print the name of the setting as well as its English
1906 description and value.
1908 Allow gdb functions to specify where a line should wrap if it
1909 exceeds the size of a terminal line. Use it to make the output
1911 * utils.c (set_screen_width_command): New fn, mallocs a buffer
1912 of the right size when screen width changes.
1913 (set_screensize_command, screensize_info): Remove #if 0'd fns.
1914 (wrap_here): New fn, indicates a point in the output where we
1915 should wrap the line rather than just letting it overflow at a
1917 (fputs_filtered): Implement wrapping.
1918 (n_spaces): New fn, returns a pointer to N spaces.
1919 (print_spaces_filtered): Use n_spaces.
1920 * defs.h (n_spaces): Declare.
1921 * stack.c (print_frame_info): Wrap with 4-space indent after
1922 fn name and before filename and line number.
1923 * printcmd.c (print_frame_args): Wrap with 4-space indent
1924 before each argument name is printed.
1925 * valprint.c (value_print): Wrap with no indentation before
1927 (val_print_fields): Wrap with indentation relative to nesting
1928 level before each field name.
1929 (val_print): Wrap with nesting indentation before array elements.
1930 * command.c (do_setshow_command): Avoid extra newlines,
1931 wrap with 4-space indent around values printed, end with period.
1932 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
1934 * breakpoint.c (breakpoint_1): Implement addressprint for
1935 "info breakpoints" display. Change file name and line number
1936 format to " at file:nnn" rather than " (file line nnn)".
1937 * gdb.texinfo: Document.
1940 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1942 Frozen for gdb-3.92.6 release.
1944 README, WHATS.NEW: Update for 3.92.6 release.
1946 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
1947 coffread.o from configs since it is now built by default.
1948 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
1949 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
1950 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
1951 from configs since it is now built by default.
1953 Makefile.dist: Update for release 3.92.6. Handle files that
1954 have been moved to ../include, ../getopt, or ../bfd. Add
1955 saber.suppress and tests directory. Add config.status to
1956 the release (it will say "none").
1958 coredep.c: Minor formatting fixes.
1960 These changes were made in early December but only checked in now:
1961 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
1962 nindy-share/nindy.c: lint
1963 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
1964 register values coming back from the target; we store values
1965 in target byte order everywhere.
1967 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
1969 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
1971 * valprint.c (cplus_val_print, val_print_fields): New functions,
1972 which print C++ objects. They conspire to avoid printing a
1973 virtual base class more than once, following all the twists and
1974 turns of C++ virtual base rules.
1975 (val_print): Call the above rather than do it by hand.
1977 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
1978 symbol file, not for added files like shared libs. This really
1979 needs to be generalized to a timestamp per file.
1981 * core.c (cleanup_core): Avoid coredump if no core file.
1983 * config.gdb: Accept -host or -target in place of +host or
1986 * coffread.c (find_linenos): Avoid desupported BFD interface
1987 to line numbers. We still read them manually rather than using
1988 BFD's "generic" features.
1990 * gdbrc.tex, threecol.tex: Add GDB reference card and its
1992 Makefile.dist: Add refcard to OTHERS list for creating tar files.
1994 * Makefile.dist: Eliminate use of $< in explicit targets.
1996 * readline/Makefile: Use $< rather than $*.c, which does not
1997 include the VPATH in GNU Make.
1999 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2000 copies of tconfig/i960, added for global configuration
2001 compatability. All i960 versions can read both coff and b.out.
2003 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2004 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2007 * TODO: Think of more things to do.
2009 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2011 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2012 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2013 64-bit float conversion.
2015 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2016 equivalent to sun?os4 so global config works.
2018 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2020 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2022 * main.c: Only declare linesize once; declare pagesize not at
2023 all, since it is never used.
2024 (main): Clear newly allocated line before it is used.
2026 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2028 Further stabilization for the Intel 960.
2030 * Makefile.dist: Parameterize the location of the "include"
2031 and "bfd" directories, as well as "getopt". Add symfile.c.
2032 Link in both dbxread and coffread. Fix up "make depend" to
2033 rewack the locations of include, bfd, and getopt in its output.
2035 * README: Document moving include files, improve some of
2038 * coffread.c: Move common code out to symfile.c. Change
2039 symbol_file_command style interface to use new *_symfile_init
2040 and *_symfile_read interface under BFD. Use BFD internal
2041 info to locate line table, symbols, etc.
2043 * core.c (core_fetch_registers): Rename to get_core_registers
2044 to avoid confusion with fetch_core_registers.
2045 (register_addr): Move to coredep.c, which is already machine
2046 dependent. This leaves core.c pretty clean of dependencies.
2048 * coredep.c (register_addr): Accept this routine from core.c.
2050 * dbxread.c: Move common code (with coffread.c, etc) into new
2051 symfile.c. Each psymtab now contains a pointer to the
2052 format-dependent function that knows how to read it in. Make
2054 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2055 (process_one_symbol): Add code to complain about a "compiler bug
2056 we muzzle here", if we actually see it.
2058 * eval.c (evaluate_subexp): Insert missing "break" statements
2059 in code that determines whether a variable is an lvalue in
2060 memory, register, or whatever. I detected this via a compiler
2061 bug in which it *almost* mashed out the whole switch statement.
2063 * gdb-int.texinfo: Add minor sections on configuring gdb for
2064 release, and about the README file.
2066 * infcmd.c (registers_info): Fix formatting somewhat. Still
2067 not as pretty as before, but it handles byte swapping.
2069 * remote-nindy.c: If data cache routines are interrupted while
2070 waiting for the remote end, be sure that any uninitialized cache
2071 blocks are on the free list, not on the valid list!
2073 * symfile.h: Flesh out this header file with all the various
2074 routines and variables that have been merged in from dbxread.c
2075 coffread.c, and symtab.c to symfile.c.
2077 * symfile.c: New file, containing code common to dbxread.c,
2078 coffread.c, and some code from symtab.c. All generic code for
2079 reading symbol files should be in here now.
2080 (unrecord_misc_function): Remove unused function.
2082 * symtab.h: Remove file-reading things to symfile.h.
2084 * symtab.c: Remove file-reading things to symfile.c.
2086 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2087 to decode i960 fault types.
2089 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2090 target.c: Change type of the "resume" function from int to void,
2091 since its result was never used.
2093 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2095 * main.c: Replace "stupid" with "caution"; you now "set caution
2098 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2100 * infcmd.c (do_registers_info): Call val_print to deal with the
2101 byte order of the registers being printed. FIXME, this makes
2102 the formatting of the output uglier.
2104 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2105 defined, call it for signals the debugger doesn't itself use.
2106 The i960 uses this for more detailed fault information.
2108 * remote.c (remote_open): If arg is null, print help rather than
2111 * sparc-xdep.c (register_valid): Avoid declaring size, since
2112 various modules will think of various sizes depending on the
2113 architecture of their tm-file. FIXME, we need protection against
2114 actually entering one of those modules, which would clobber
2115 storage if not for the target architecture compiled into gdb.
2117 * stack.c (up_command, down_command): Always print the frame
2119 (up_silently_command, down_silently_command): New commands
2122 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2124 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2125 more parameters than it used to.
2127 * findvar.c (registers): Increase slop to 256 bytes, which should
2128 protect us against even most RISC machines with large register
2130 (locate_var_value): Move declaration inside related ifdef.
2132 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2133 throughout, to avoid throwing away buffered input from the board.
2134 (nindy_wait): Supply_register takes addr_of_value, not value.
2135 (i960_print_fault): Renamed from i80960_fault.
2136 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2137 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2139 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2140 we can set the PC in the call to proceed(). Unpush nindy_ops
2141 before pushing it on top, to avoid message to user. Eliminate
2142 commentary from Unix machines that just misleads here.
2143 (reset_command): Fix error message to suggest target command.
2145 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2147 Release 3.92.5 as frozen.
2149 Stabilize the merged release...with help from lint, Saber C,
2152 Everywhere: Add include files needed to declare return types
2153 of functions called.
2155 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2157 * breakpoint.h: Add undeclared breakpoint functions, and some
2158 functions for display handling since I couldn't think of a better
2161 * breakpoint.c (insert_breakpoints): Make code for disabling
2162 shared library bkpts more likely to work. It's used when we
2163 rerun a program and stop before the shared library has been
2165 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2166 cast from pointer, so it squeezes through catch_errors.
2167 (bpstat_stop_status): Fix logic broken some time ago. We now
2168 always create a bpstat if the stop address matches a breakpoint,
2169 even if we don't stop there -- just like the old code used to do
2170 before I got my fingers into it (sigh).
2171 (breakpoint_1): Print "ignore count" after "stop only if"
2172 condition, since that's how it actually works.
2173 (mention): Handle watchpoints as well as breakpoints.
2174 (watch_command): use set_raw_breakpoint and mention to do most
2175 of the work (and initialize all the fields!). Only pass one
2176 arg to parse_c_expression, since that's all it takes.
2178 * command.c (not_just_help_class_command): Rename arg to args
2179 since we ignore "unused argument" warnings on vars named "args".
2180 inflow.c (child_terminal_info): ditto.
2181 infptrace.c (kill_inferior): ditto
2182 main.c (catch_errors, version_info, quit_command, pwd_command,
2183 source_command, dump_me_command, editing_info,
2184 set_history_size_command, set_history, show_history,
2186 stack.c (locals_info): ditto
2187 target.c (target_files_info): ditto
2188 valprint.c (set_input_radix, set_output_radix): ditto
2190 * core.c: Remove old variables for handling core and exec file
2191 sections (data_start, data_end, stack_start, stack_end,
2192 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2193 text_end, exec_data_start, exec_data_end, text_offset,
2194 exec_data_offset, data_offset, stack_offset). They're
2195 superseded the more general build_section_table and
2197 (get_exec_file): Mention the `file' command.
2198 (read_memory_check): Rename to memory_error, and only call it
2199 in the case of an actual error.
2200 (read_memory, write_memory): call memory_error.
2201 (core_fetch_registers): Register section name is ".reg".
2203 coredep.c: Remove a bunch of crud now that all this file does
2204 is pull the registers out of a core file.
2205 (fetch_core_registers): Rewrite to actually work, I hope.
2207 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2208 Replace index() with strchr(). Remove all the pre-BFD macro
2209 definitions for accessing the symbol file.
2210 (struct dbx_symfile_info): Encapsulate the information that
2211 dbx_symfile_init needs to pass to dbx_symfile_read in this
2214 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2215 dbx_symfile_discard): Rearrange symbol file reading to divide
2216 the format-specific part from the format-independent part,
2217 leaving the format-independent part such as file name expansion
2218 and opening in symtab.c. This replaces
2219 partial_symbol_file_open and partial_symbol_file_read.
2220 Symbol_file_read, add_file, add_file_target_command,
2221 add_file_addr_command move to symtab.c. Pass an explicit
2222 "mainline" flag for when reading the main symbol table, rather
2223 than relying on the offset address to be zero or nonzero.
2225 (dbx_symfile_read): Don't allow void *'s to be printed as
2227 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2228 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2229 macro" debug version really work.
2230 (read_dbx_symtab): Remove unref'd parameter inclink.
2231 Avoid swapping N_SLINE symbols, for speed.
2232 Merge N_TEXT!N_EXT case with the other external symbol
2233 definitions' case. Add comments.
2234 (start_psymtab): Allocate the symfile name in the psymtab on
2235 the psymbol_obstack, rather than using the caller's storage.
2236 (end_psymtab): Only allocate a dependencies list if there are
2238 (psymtab_to_symtab_2): Use BFD when reopening file to read
2239 its symbols for real.
2240 (read_struct_type): Add FIXME comments where it needs work
2242 (read_huge_number): Add FIXME about overflows.
2243 (read_range_type): Add FIXME about comparing a long to 1<<32.
2245 * coffread.c: Minor changes to move things closer to the new
2246 regime with symtab.c and dbxread.c Major work is still needed
2249 * exec.c (exec_file_command): Remove old variables (see core.c
2251 (xfer_memory): If memory transfer is right at the end of a
2252 section, don't lose.
2254 * findvar.c (get_saved_register): If value is in a real
2255 register, LVAL is lval_register, not lval_memory.
2257 frame.h: Declare print_sel_frame and record_selected_frame.
2259 gdb-int.texinfo: New file, for GDB internals documentation.
2260 Very simple, unformatted doc of cleanups is there for now.
2262 gdbcore.h: Remove obsolete variables that described a.out
2263 section addresses and offsets. (See core.c above.)
2264 Declare fetch_core_registers and registers_fetched.
2266 getopt.c: Declare char *alloca(); even on SPARC.
2268 infcmd.c (run_command): Call target_kill rather than
2270 (step_command, next_command, stepi_command, nexti_command):
2271 Declare from_tty parameter even though we don't use it.
2272 (run_stack_dummy): argument BUFFER is a char array, not
2273 a pointer to REGISTER_TYPE.
2274 (finish_command): using_struct_return needed a value *,
2275 not a struct symbol *.
2277 * infptrace.c (child_xfer_memory): To avoid dependency on
2278 where sections are in memory, try PT_WRITE_D and if that fails,
2279 try PT_WRITE_I. Most Unixes don't care which you use.
2281 * infrun.c (step_resume_break_shadow): Change to array to
2282 match other breakpoint shadow storage.
2283 (clear_proceed_status): Pass address of bpstat to
2284 bpstat_clear, not the bpstat itself.
2285 (child_create_inferior): FIXME comment about if the child
2287 (start_inferior): Remove old function.
2288 (child_open): Use target_kill rather than kill_inferior.
2289 (wait_for_inferior): Ditto.
2290 (insert_step_breakpoint, remote_step_breakpoint): Use
2291 new step_resume_break_shadow.
2293 * inftarg.c (child_wait): If all child processes die,
2294 pretend that the one being waited for exited with signal 42.
2296 * main.c (command_line_input): When scanning for comments,
2297 don't coredump on unclosed quotes.
2298 (quit_command): Use target_kill rther than kill_inferior.
2299 (_initialize_main): Rename class_user from "user" to
2302 * printcmd.c (print_command_1): Initialize "fmt" if no format
2303 is specified by the user.
2304 (print_frame_args): Only add to args_printed if we are
2305 actually fetching args from the stack (avoiding undefined
2307 (_initialize_printcmd): Remove bogus \{ from string.
2309 * remote-eb.c (eb_open): Avoid coredump on no argument.
2311 * remote-nindy.c: Bring out of Intel environment into new
2312 target environment. Remove all conditional compilation on
2313 I80960. Massive hacking throughout.
2314 (nindy_xfer_inferior_memory): New routine stolen from
2316 (nindy_create_inferior): New routine pieced together, probably
2317 not quite working yet.
2318 (nindy_ops): New target_ops struct for nindy.
2320 * remote-vx.c: Use write_memory rather than target_write_memory
2321 to get error checking.
2322 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2324 (vx_create_inferior): Use target_terminal_ours...
2326 * signame.c (_initialize_signame): Always initialize, since
2327 we need the table for things other than psignal.
2329 * solib.c (solib_add): Use symbol_file_add, not add_file.
2330 (solib_address): Return boolean result rather than struct
2331 pointer which nobody else knows the type of.
2333 * sparc-tdep.c, valops.c: Use write_memory rather than
2334 target_write_memory, to get error checking.
2336 * stack.c (locals_info, catch_info, args_info,
2337 get_selected_block, frame_command, up_command): Use
2338 target_has_stack, rather than have_inferior_p or
2341 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2343 * symfile.h: New file, defining the interface between the
2344 generic and object-file-specific symbol reading code.
2346 * symtab.c: Move generic symbol-reading interface to symtab.c,
2347 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2348 table to map BFD targets to symbol-reading modules in GDB.
2349 Change index to strchr.
2350 (lookup_struct_elt_type): Use error() rather than hand-made
2351 simulations thereof.
2352 (lookup_partial_symbol): Speedup slightly when length == 0.
2353 (symbol_file_add): New function.
2354 (symbol_file_command): Call it.
2355 (symfile_open, symfile_init): New function.
2356 (add_file_target_command, add_file_addr_command): moved from
2359 * target.c (target_command): use target_kill.
2361 * target.h (target_files_info): Don't declare, never called
2364 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2365 files to determine stack end address.
2367 * valarith.c (value_x_binop, value_x_unop): Change error message
2368 to be more useful. Pass proper argument to value_struct_elt.
2370 * valops.c (value_assign): FIXME comment that long long
2371 bitfields will break here.
2373 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2374 Update `make saber_gdb' to work better.
2376 * TODO: A woman's work is never done.
2378 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2379 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2380 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2381 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2382 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2383 valops.c, valprint.c, exec.c: Lint.
2386 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2388 Continuing Intel 960 port merge of GDB.
2390 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2391 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2392 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2393 Wack over "make depend" so it handles files in subdirectories
2394 vx-share, nindy-share, bfd, and in the current directory.
2396 * blockframe.c (get_prev_frame_info): Remove fatal error
2397 if stack not defined.
2399 * core.c (core_open, core_detach): New functions that handle
2400 the old "core-file" command as "target core" and "detach" instead.
2401 (core_file_command): Call them.
2402 (core_xfer_memory): Use common routine xfer_memory.
2404 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2405 dbxread now uses bfd for everything but symbol reading itself.
2406 BFD internals are used to drag out the relevant file offsets.
2407 (partial_symbol_file_open): Change args all around for BFD.
2409 * symtab.c: Rename "value" to "val" everywhere, so we can
2411 (symbol_file_command): New command, moved from dbxread.c
2412 and coffread.c. It uses BFD to read the file, then vectors
2413 based on its type, to dbx or coff symbol readers.
2414 * symtab.h: Extern a few vars for symbol_file_command.
2416 * target.h: Breakpoint takes a char * save area, not a char **.
2418 * valprint.c (val_print): When unpacking bitfields, offset
2419 the address in gdb of the value, if it is declared with a shorter
2420 type. Remove the last "runtime kludge test" of host byte order.
2422 * utils.c: Remove old my_bfd_read routine.
2424 * stack.c (frame_info): Use target_has_stack. Print program counter
2425 register's actual name rather than "pc", since it's called the
2426 "ip" (instruction pointer) on the i960 (sigh).
2428 * target.c (target_command): Add command for selecting a target
2429 type and calling its open routine. This is used for initiating
2430 communication with a particular target, in a generic way.
2432 * tm-i960.h: Update for modern gdb. Remove semicolons from
2433 various macros. Handle reading struct return convention, and
2434 error-out attempts to return structs with the "return" command.
2435 Be sure gdb doesn't think we know how to call functions in the
2438 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2439 to i960_xxx in lower case.
2440 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2441 not being defined yet.
2443 * remote.c (remote_open): Call start_remote to initialize
2444 wait_for_inferior during open.
2445 (remote_xfer_inferior_memory): Return length written rather
2448 * remote-vx.c (target_command -> vx_open): Use new generic
2450 * remote-eb.c, inftarg.c, exec.c: ditto.
2452 * infrun.c: Fix comments.
2453 (attach_program -> child_open): Use new generic target command.
2454 (wait_for_inferior): Clear saved register values before target_wait,
2455 so target_wait can set some of them if convenient.
2457 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2458 Return success indicator, not void.
2459 (child_xfer_memory): Avoid fetching initial word if we'll
2460 overwrite it anyway.
2462 * infcmd.c (attach_command): Use new generic target open routine.
2463 (_initialize_infcmd): Update doc on attach and detach commands.
2464 (do_registers_info): Merge in a byte-order problem as a FIXME
2467 * findvar.c (find_saved_register): Avoid problem in current frame.

2480 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
2481 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.

2485 Merge Intel 960 port of gdb, continuing...
2487 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
2488 symbol_file_command): Pass from_tty arg to hush 'em up.
2490 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
2491 Add magic numbers for 960 COFF format.
2493 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
2495 Merge Intel 960 port of gdb, from Intel "1.2" release.
2497 CHANGE_LOG entries from their port, which was based on

2516 Fri Apr 20 13:47:15 PDT 1990
2519 Thu Apr 19 09:54:28 PDT 1990
2520 Add 'reset' command.
2522 Wed Apr 18 09:48:07 PDT 1990
2523 After opening remote tty, wait for 1 second to go by without input
2524 from it before trying to talk to NINDY (fixes problems with the
2525 Heurikon HK80/V960E).
2527 Mon Apr 4 16:33:05 PDT 1990
2528 Some output was not being suppressed in 'batch' mode.
2530 Thu Mar 22 15:31:11 PST 1990
2531 Ask user if old symbol table should be deleted when new file is
2534 Allow user to run a program downloaded before gdb960 was brought up.
2536 Correct "exec-file" help message for i80960 context.

2546 code loaded at addresses higher than 0x7fffffff.
2548 Wed Jan 10 12:43:22 PST 1990
2549 Open remote tty for exclusive use.
2551 Fri Jan 5 12:14:42 PST 1990

2561 Mon Oct 2 15:56:31 PDT 1989
2563 Added 960CA disassembly support.
2565 To simplify maintenance:
2566 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
2568 - eliminated opcode.h: incorporates tables into i960-pinsn.c
2569 - moved 960-specific routines from i960-pinsn.c to i960-md.c
2570 - made disassembly interface identical to that in gdmp960.
2574 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
2576 * target.h: Allow targets to stack. Add target_has_memory,
2577 _registers, etc. Restructure memory access and "info files"
2578 to walk the target stack.
2579 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
2580 target.c: Change tables to match target.h.
2581 * inflow.c (child_mourn_inferior): pop child_ops.
2582 (generic_mourn_inferior): Use new has_stack flag.
2583 * infptrace.c (child_xfer_memory): New memory regime.
2584 * inftarg.c (child_files_info): New "info files" regime.
2585 * remote-eb.c: New memory regime, new info files.
2586 * remote-vx.c: New memory regime, new info files. Now use
2587 separate targets for VxWorks attachment to machine, and
2588 actually running a process under VxWorks, since one has
2589 stack & execution & regs and the other doesn't.
2590 * remote.c: New memory regime, new info files.
2591 * sparc-xdep.c (fetch_core-registers): New memory regime.
2592 * target.c: New routines and support for stacked targets,
2593 new memory regime, new info files regime.
2596 Generalize section handling for an arbitrary number of sections,
2597 including use of the new BFD (binary file) library.
2598 * gdbcore.h: Add struct section_table.
2599 * exec.c (build_section_table): Iterate all sections and
2600 record what gdb needs to know about them.
2601 (exec_command): Use it.
2602 (exec_xfer_memory): Use the table.
2603 (exec_files_info): Print the table.
2604 * core.c (core_file_command, core_xfer_memory, core_files_info):
2606 * source.c (find_source_lines): Use bfd_get_mtime.
2607 * dbxread.c: Quick changes to make it compile with new BFD.
2608 * utils.c (error): Avoid using bfd_error in generic routines.
2610 * core.c (core_fetch_registers): Get from the ".regs" section of
2612 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
2614 * inferior.h (attach_flag): Export.
2615 * infcmd.c (run_command): use new target_create_inferior.
2616 * infrun.c (child_create_inferior): Don't return result.
2617 * Makefile.dist (VERSION): 3.91.4.
2619 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
2621 * breakpoint.c (bpstat_num): Handle breakpoints which have
2622 since been deleted, such as temporary breakpoints.
2623 infcmd.c (program_info): ditto.
2625 * core.c (core_file_command): Display the frame where the core
2630 * remote-vx.c (target_command): Merge in target command from
2631 targ-vx.c. A few other cleanups.
2633 * TODO, Projects: Lots more stuff to do...
2635 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
2637 Massive changes to wall off the remote-debugging interface
2638 behind a function vector. The port to handle VxWorks targets
2639 is also part of this.
2641 All files: Replace references to renamed functions,
2642 remove references to remote_debugging, remove references to
2643 have_include_file, have_core_file in favor of target_has_stack,
2644 target_has_memory, etc.
2646 * Modularize the breakpoint interface.
2647 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
2648 a breakpoint instruction.
2649 breakpoint.c: struct breakpoint's shadow_contents now sized as
2651 (insert_breakpoints): Vector to target to install breakpoints.
2652 (remove_breakpoints): Vector to target here too.
2653 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
2654 sparc-tdep.c (single_step): Use new breakpoint interface for
2655 the single-step breakpoints.
2656 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
2657 New file, contains routines to insert and remove breakpoints by
2658 reading out the old contents and later replacing them. This is
2659 how ptrace breakpoints work, and many remote systems as well.
2661 * tm-vxworks68.h: New config file, overrides a few things for
2662 Wind River's preferences.
2664 * target.h: New file, for transfer vector used to talk to the
2665 inferior (child, attached, core, exec, remote, etc). All accesses
2666 to the thing being debugged should come through these vectors.
2667 target.c: New file, routines to handle transfer vector.
2668 (various files): Add transfer vectors XXX_ops for the various
2669 targets and pseudo-targets (core files, etc) we support.
2671 * breakpoint.c (bpstat_stop_status): Further explorations of
2672 watchpoints and why things don't work all the time.
2673 (bpstat_alloc): New fn to allocate a bpstat and chain it.
2675 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
2676 the local gdbinit if it doesn't already have it.
2678 * core.c (core_ops): add and install.
2679 Allow core debugging without exec file.
2681 * dbxread.c (free_and_init_header_files): Merge two fns.
2682 (end_symtab): Free named symbol table when a new version comes in.
2683 (read_dbx_symtab): Relocate all kinds of symbols with base
2684 address. First step toward handling different text, data, bss
2686 (add_file_addr_command): Renamed add_file_command.
2687 (add_file_command): Vector to remote handler.
2688 Add "load" as an alias for "add-file" command.
2690 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
2691 non-returning functions.
2693 * exec.c: Add exec_ops, and push it as a target when an exec
2696 * infcmd.c (run_command): Pass executable file name and arg list
2697 separately when starting an inferior. Permit "run" when no exec
2698 file is specified, for VxWorks.
2699 (detach_command): Move to child_detach in inftarg.c.
2701 * inftarg.c: New file. Unix-child-specific routines, and the
2702 child_ops structure.
2704 * inferior.h (registers): Export "registers" as the way for
2705 target dependent register handlers to find gdb's local copy of
2706 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
2707 since it is now used by places that want wait_for_inferior to
2708 handle the grunge but want to see every trap from the inferior.
2710 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
2711 Eliminate remote_debugging hooks in terminal handling.
2713 * infrun.c: Replace start_inferior with child_create_inferior.
2714 Move all the hair of Unix shells and ptrace idiosyncracies into
2715 child_create_inferior, so remote handlers don't have to deal.
2716 Remove running_in_shell. Rename stop_after_attach to
2717 stop_soon_quietly, and use it in a few other places where we want
2718 to just call wait_for_inferior and get control back on the first
2719 trap. trap_expected now never takes a value > 1.
2720 (init_wait_for_inferior): Initialize static vars when a new
2723 main.c (gdbinit): Add new hook for .gdbinit file name, let
2724 it be overridden by config files as GDBINIT_FILENAME.
2725 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
2726 Both of these are used for VxWorks gdb.
2728 mcheck.c: rename include file "gmalloc.c" to avoid problems
2729 with system include file "malloc.c".
2731 param-no-tm.h: New include file, same as param.h but does not
2732 include the default "tm.h" file. This is used in files where
2733 the target is known, e.g. remote-eb.c or sparc-xdep.c.
2735 param.h: Now just a shell that includes tm.h and param-no-tm.h.
2737 remote-vx.c: New file, VxWorks remote debugging support. Uses
2738 RPC routines that are shared with the target system, in directory
2741 remote.c: Vectorize remote interface.
2743 source.c: Globalize source_path, and make an alias "l" for "list"
2744 since we now have the "load" command.
2746 sparc-xdep.c: Use new param-no-tm.h.
2748 symmisc.c (free_named_symtab): Add new function from Wind River.
2749 However, ifdef it out for now while we think about what it should
2752 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
2754 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
2755 non-Unix-children handle this with their own code in the target
2758 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
2759 source and target lists. Add vx-share to default list of include
2760 directories. Add new files to src and target lists: mem-break,
2761 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
2762 ${srcdir} versions of munch and createtags are used.
2764 * valops.c (find_function_addr): Split out of call_function.
2765 (call_function_by_hand): Rename call_function; this function
2766 calls functions in the target by laboriously patching the target
2767 word-by-word with the right stack, args, regs, etc.
2770 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
2772 Handle AMD 29000 a bit better.
2774 * remote-eb.c (readchar): Mask received char log to make it readable.
2775 (remote_start): Pass arguments down to executing program.
2776 Make startaddr unsigned.
2777 infrun.c (start_inferior): Accept args, pass them to
2779 infcmd.c (run_command): Pass args down to start_inferior.
2781 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
2782 the target object file format.
2783 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
2785 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
2786 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
2788 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
2790 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
2791 * TODO: We did a few things, we have more to do though.
2793 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
2794 * inflow.c (inferior_died): Clear deferred stores.
2796 * Debug problems with dummy frames and calls to the inferior.
2797 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
2798 * sparc-tdep.c (do_restore_insn): Simplify.
2799 (sparc_frame_find_saved_regs): Simplify and fix what we find.
2800 (sparc_push_dummy_frame): Simplify and fix what we push.
2801 (sparc_pop_frame): Slightly more hair here, deciding whether
2802 we are restoring a saved PC or returning to a return address in %i7.
2803 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
2805 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
2806 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
2807 * obstack.h (chunkfun): ditto.
2808 * defs.h (xmalloc, xrealloc): ditto
2810 * utils.c (quit): Grab the terminal from the child if necessary.
2812 * inflow.c (term_status_command): Rename to term_info, change
2815 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
2816 (is_delayed_branch): Speed up.
2817 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
2818 Still missing some float ops, and needs testing.
2820 * Support for input and output radixes other than base 10
2821 * defs.h (input_radix, output_radix): Declare.
2822 * expread.y (yyparse, parse_number): Handle changes of input
2823 radix, and ambiguous names-or-numbers in radixes >10.
2824 * printcmd.c (print_scalar_formatted): Print formatted hex
2825 numbers in varying column widths.
2826 * valprint.c (val_print): Use output_format to print scalar ints.
2827 (set_input_radix, set_output_radix, set_radix): Create.
2828 (set_output_radix): Set output_format from output_radix.
2829 (_initialize_valprint): add `set radix' but leave the others off.
2831 * main.c (execute_command): Let stupid questions be turned off.
2832 (_initialize_main): Handle "set stupidity", etc.
2834 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
2835 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
2837 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
2839 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
2840 bfd stuff is still screwed up, but with some manual work, it
2843 * breakpoint.c (bpstat_do_actions): Start over if a command
2844 proceeds the inferior, since the inferior will have stopped and
2845 will need to have its new stop-actions taken care of.
2847 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
2848 compiler fits, simplify it.
2850 * gdb.texinfo (directory command): Doc new dir command.
2851 source.c (directory_command): "dir" now puts things on the front
2852 of the path, moves dups up front, and handles multiple names
2853 on the command line, inserting each one in order. It also
2854 blows away cached line and full_filename info.
2856 * stack.c (backtrace_command): Skip "more stack frames follow"
2859 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
2860 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
2861 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
2862 The only odd one was Gould NP1, which had defined vprintf to
2865 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
2866 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
2867 variable, inspect_it.
2868 valprint.c (print_string, val_print): Use the global inspect_it
2869 to indicate whether to print in Epoch style or normal style.
2871 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
2873 * printcmd.c (call_command): add an alias for the "print" command
2874 which runs expressions and doesn't print the result if void.
2875 (print_command_1): implement it.
2877 * command.c: Remove #if 0'd code. Initialize all the fields
2878 in add_cmd (). Rename do_nothing_command to
2879 not_just_help_class_command, and make it externally visible.
2880 command.h: add user_commands to struct.
2881 * main.c (define_command): Don't overload c->function with a char
2882 string as well as a function pointer.
2884 * eval.c (evaluate_subexp): Reinstall tiemann changes to
2885 calling convention of value_struct_elt () that got dropped in
2888 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
2889 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
2891 * tm-sparc.h (POP_FRAME): replace some constants with defines.
2893 * sparc-xdep.c (store_inferior_registers): defer stores to regs
2894 until a good time (e.g. when we are about to run the child),
2895 saving ptrace calls.
2896 * infrun.c (proceed): handle DO_DEFERRED_STORES.
2897 * tm-sparc.h: define DO_DEFERRED_STORES.
2899 * sparc-xdep.c (store_inferior_registers): when storing float
2900 registers, don't store stack regs too. When storing the SP,
2901 however, DO store the stack regs too. This fixes a bug in which
2902 the dummy frame is not recognized when a call_function finishes,
2903 because its frame pointer (in the stack regs) was never
2905 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
2906 even though we don't know how to read them from an inferior.
2907 valops.c (call_function): Comment about storing SP.
2909 * infrun.c (save_inferior_status): Save away the original bpstat
2910 chain so it can be restored later. Install the copied version for
2911 use by whoever saved the status. It will be blow away by
2912 restore_inferior_status, and the original chain restored. This is
2913 important for people who have pointers into the original.
2915 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
2916 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
2917 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
2920 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
2922 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
2923 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
2924 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
2926 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
2928 * Merge Mike Tiemann's multiple inheritance changes from Sun.
2929 Store the baseclasses in a type struct starting from array element
2930 0 rather than from the unusual array element 1.
2932 dbxread.c: the above.
2933 (virtual_context): Add
2934 Read new debug information about which virtual function table
2935 a virtual function is from, and store it in fn_field.fcontext.
2937 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
2938 TYPE_FN_FIELD_STATIC_P.
2940 symtab.c: the above.
2941 valops.c: the above. Handle pointer casts of object *'s.
2942 (search_struct_method): Add.
2943 (value_struct_elt): First arg is now a pointer to a value, and is
2946 valprint.c: the above.
2947 values.c (value_virtual_fn_field): Add type arg. Handle
2948 offsetting to the proper object when calling virtual fns.
2950 (baseclass_addr): Add valuep arg.
2952 * README: Document the current state of BFD config (missing).
2953 * TODO, ChangeLog, Makefile.dist: Roll version.
2954 * WHATS.NEW: Add summary of changes since 3.5.
2956 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
2958 * dbxread.c (read_struct_type): Clear bit vectors whenever
2960 symtab.c (B_CLRALL): define.
2962 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
2963 using == rather than =. Huh... This fixes the dreaded problem
2964 wherein builtin_type_int becomes TYPE_CODE_FLT.
2966 * core.c (info_files): Show the inferior pid.
2968 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
2969 already knows how to look in the source directory.
2971 * Remove psymtab hair from many places. Remove duplicated code
2972 for searching symbol tables. Hide psymtabs from most places.
2973 Make it fast to get from a psymtab to its symtab.
2975 blockframe.c (blockvector_for_pc): Remove psymtab hair.
2976 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2977 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2978 dbxread.c: export psymtab_to_symtab, make it work if called N times.
2979 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
2980 new symtab completely. New psymtabs get symtab pointer
2981 initialized to zero. Remove MI warning printf.
2982 symtab.h: Comments. Add psymtab to symtab pointer.
2983 (PSYMTAB_TO_SYMTAB): New macro.
2984 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
2985 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
2987 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
2989 (print_frame_info): Avoid special-casing symbols that have not yet
2992 * source.c (open_source_file): Quick path if we have already
2993 located the source file by its full name.
2995 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
2996 find_pc_psymtab. When a name is found in the misc function
2997 vector, search the symbol table for its mangled name, not the
2998 name that the user typed.
3000 * bfd.h: Fix missing comment terminators, make #endifs match.
3002 * valarith.c (value_less): Handle unsigned int comparisons.
3003 Add FIXME about pointer compares, which assume host and target
3004 pointers are the same.
3006 * command.c (do_nothing_command): lint
3007 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3008 fix comments on debug symbol format for visibility. Actually set
3009 visibility of symbols.
3010 main.c (echo_command): lint; use <readline/history.h>.
3011 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3012 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3013 pointing past end of allocated memory; saber complains.
3014 obstack.h: Declare the external functions that we use.
3015 valarith.h: use <string.h>
3016 solib.c (solib_add): lint.
3018 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3020 * main.c (initialize_main): Default info_verbose to off, now that
3021 symbol reading is fast.
3022 (quit_command): Avoid clobbering exec_bfd while quitting.
3024 * Initial BFD (binary file diddling library) merger:
3025 coffread.c: Change AOUTHDR to struct exe_hdr.
3027 core.c: initialize initialized data at compile time.
3028 (core_file_command): Move from coredep.c, convert to bfd.
3029 (xfer_core_file): Convert to bfd.
3030 exec.c (exec_file_command): use bfd routines.
3032 mips-tdep.c: Remove exec_file_command and friends.
3035 * coredep.c: (fetch_core_registers) Convert core_file_command to
3036 fetch_core_registers.
3037 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3039 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3040 (my_bfd_read): More bogosity, which I don't think we call.
3041 (program_name): Remove this atrocity asap!
3043 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3046 values.c: allocate_repeat_value was not clearing the
3047 optimized_out field.
3048 (value_static_field): minor stylistic fix (wrong macro was used).
3049 valops.c (value_struct_elt_for_address): didn't work for C++
3052 * signame.c (_initialize_signame): Initialize signal names once.
3054 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3055 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3056 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3058 * remote-eb.c: Support user-settable baud rates on the serial port.
3060 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3062 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3064 * tconfig/sun3os4: Remove warning about native assembler,
3065 since it also occurs in the xconfig file.
3067 * findvar.c (registers): Allocate some slop after `registers'
3068 to prevent stray accesses from trashing the next variable.
3070 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3071 on the sun-3, by changing the #ifdef from `sun3' (which is not
3072 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3073 vars, which happened to follow `registers' in the executable.
3075 * readline/history.c (history_search): Heed gcc-2's advice
3076 and parenthesize && inside ||).
3078 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3079 tm-29k.c: Insert FSF copyright headers.
3081 * remote-eb.c: Better comments.
3083 * Makefile.dist: Update to 3.91.6.
3084 * TODO: note PREPARE_TO_STORE problem.
3086 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3088 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3090 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3092 * infrun.c (wait_for_inferior, at end): Don't set up
3093 prev_* if the inferior no longer exists.
3095 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3096 CANNOT_EXECUTE_STACK.
3097 valops.c (call_function): Use it.
3099 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3101 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3102 infrun.c (wait_for_inferior, 2 places): Use it.
3104 * values.c (value_being_returned): Only use
3105 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3107 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3108 right thing for remote-eb.c.
3110 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3111 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3113 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3114 (FRAME_FIND_SAVED_REGS).
3116 * findvar.c ({fetch,store}_registers): Check for
3117 REMOTE_{FETCH_STORE}_REGISTER macro.
3119 * findvar.c (get_saved_register): Add argument lval and
3120 change meaning of argument addr.
3121 findvar.c: Change calls to get_saved_register to reflect
3122 new calling convention.
3123 valops.c (value_assign): Use get_saved_register instead of
3124 find_saved_register.
3126 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3128 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3129 an (uninitialized) pointer to one. Use "&" when passing it
3132 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3134 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3137 * coffread.c (symbol_file_command): Put semicolon after
3139 Put safe_to_init_tdesc_context in #if defined (TDESC).
3140 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3141 coffread.c: #include <sys/stat.h>.
3142 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3143 Add missing ')' in check for "lc%" and friends. Remove
3145 Declare read_one_sym() at top of file.
3146 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3147 MC68WRMAGIC can have the same value without causing a duplicate
3150 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3152 * Allow a Makefile to be built without building the
3153 tm and xm file links that screw up builds in subdirectories.
3154 This is done with `config.gdb none', then you can do things
3155 like `make gdb.tar.Z'.
3156 * tconfig/none: Config file for no target system
3157 * xconfig/none: Config file for no host system
3158 * config.gdb: If no TM or XM files are called out by the
3159 host or target file, don't make links for them.
3161 * cplus-dem.c: Add documentation.
3163 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3164 simple error, so the user's gdb doesn't crash due to some object
3165 file problem (e.g. somebody is rebuilding the file out from under
3168 * printcmd.c (print_address_symbolic): demangle the symbol.
3170 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3171 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3172 (alldeps.mak): sort and uniq all results from this; duplicates
3173 hose gdb.tar.Z link building. Remove RCS files from
3174 tconfig and xconfig. Add config files for sun386. Add
3175 a few odd files to OTHERS and HFILES.
3177 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3179 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3180 Roll version number to 3.91.5. Make lint work in bindir.
3182 * README: Document cross-debugging and new file structure.
3184 * blockframe.c: Lint. Include "value.h" to declare read_register.
3185 (find_pc_partial_function): remove duplicate line.
3187 * command.h: Lint. Declare error_no_arg and dont_repeat.
3189 * tm-news.h: Remove inadvertently duplicated stuff.
3191 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3192 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3194 * config.gdb: Allow `config.gdb host target' form. Clean
3195 up previous change that printed bogus messages when you just said
3198 * core.c: #include "command.h" for lint.
3201 * main.c: Remove some casts of enums. Lint.
3208 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3210 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3211 read it from memory. This will allow us to save ptrace calls
3212 eventually. Changed caller single_step too.
3214 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3215 that we aren't going to use, saving many ptrace calls, especially
3216 when watchpointing or single stepping. Use some #define's for
3218 (store_inferior_registers): Ditto.
3219 (core_file_command): Use some #define's for constants.
3221 * tm-sparc.h: Add #define's for some register numbers, so we
3222 can eliminate the use of random constants in sparc-xdep.c.
3224 * stack.c (frame_command, print_frame_info, up_command,
3225 down_command) Remove frame_changed, since it
3226 causes a bug and doesn't seem to do anything useful. In some
3227 places it was used as a flag, in others as a stack level (?).
3229 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3230 default is to use the portable (vprintf) version rather than the
3232 * xm-news.h (MISSING_VPRINTF): Add.
3234 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3236 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3238 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3239 about linking debugged programs -Bstatic in the sun?os4 config
3240 files in tconfig and xconfig subdirectories.
3242 * main.c (main): Remove unreached exit(0) now that we exit
3245 * Create TODO file for online bug list. There are too many
3246 "little" bugs to keep track of on paper.
3248 * Change Projects file to refer to bug-gdb@cygnus.com
3249 rather than kingdon@ai.
3251 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3253 * Makefile.dist (VERSION): 3.91.4 now.
3255 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3256 (condense_misc_bunches): Add sanity check that misc_count is
3257 the same as the number of symbols in the bunch.
3259 * coffread.c: rename init_misc_bunches. Pass an argument
3260 to condense_misc_bunches (a zero).
3262 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3263 every time we are called; don't rely on our caller to do it.
3264 (add_file): Remove call to init_misc_bunches.
3266 * mipsread.c: Only warn, don't error, if unknown symbol types.
3267 This keeps an old gdb from falling on its face if it sees newly
3268 extended symbol info. Rename init_misc_bunches.
3270 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3272 * Merge in changes from Per Bothner for DECstations and other
3273 MIPS stuff. The rest is Bothner speaking:
3275 The next message is a merger of Alessando Forin's mips port with
3276 mine. I've tried to use my good if biased judgment to get
3277 the best of both. It *does* need testing.
3279 Some of the changes are general, *not* mips-specific.
3282 Didn't believe in little-endian bit order.
3283 There are still inconsistencies about whether flags
3284 like BITS_BIG_ENDIAN are integer (#if ...) or
3285 boolean (#ifdef ...). I tried to paper over them.
3287 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3288 Moved some misc_function code that was common to
3289 {dbx,coff,mips}read.c to symtab.c.
3290 In the process, I think I cleaned things up a bit.
3291 At the same time, moved obsavestring and obconcat to symtab.c.
3294 Removed obsolete condense_addl_misc_bunches (use
3295 condense_misc_bunches(1) instead).
3298 Needed to include <sys/dir>, at least on DECstations.
3300 valops.c, mips-tdep.c, tm-mips.h:
3301 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3302 conventions (when STACK_ALIGN is insufficient).
3303 Needed on mips, where doubles need 8-byte alignment,
3304 but ints only need 4.
3307 Removed cruft that was not being used.
3308 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3311 Print $ before register-names (I think that makes things a little
3313 Never print two instructions, even if one delays.
3314 Removed hex-disassemble set_cmd. (This is not mips-specific,
3315 so I think the argument is whether it is generally worthwhile or not.
3316 I'm inclined to think not, given how easy it is to
3317 convert between radixes in gdb.)
3320 This is basically Alessando's code.
3321 It doesn't use obstacks; I changed it to use obstacks
3322 in a few minor places where using malloc causes a
3323 memory leak. (Probably, more places could/should be changed.)
3324 I added record_misc_function where it was missing.
3325 In symbol_file_command and add_file_command, I tried
3326 to make the code consistent with more recent versions.
3327 Minor sylistic changes in parse_procedure.
3328 Make a .gdbinfo. psuedo-symbol point back to the real
3329 procedure symbol (using the isym field).
3332 This is basically from my port, but with a lot of details
3333 and a number of routines merged in from Alessando's version.
3334 I basically used my code "raw" backtrace (use heuristics
3335 from the actual code, rather than symbol table info) - though
3336 the idea is Alessandro's. I feel my code is a little cleaner
3337 here, particularly in being a little more flexible, such as being
3338 able to handle gcc-produced code (which it now can).
3339 It also doesn't do frame caching (which is not useful
3340 more recent gdb versions).
3341 I also used my code for push_/pop_dummy, more or less.
3342 I tried to incorporate AF's code for testing sigtramp
3343 while backtracing; I probably got it wrong.
3344 Added mips_print_register, which tries to scrunch as much
3345 information as possible on a screen...
3346 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3347 under mips-pinsn.c), I don't see anything mips-specific here,
3348 and I don't see it being all that useful anyway.
3351 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3352 Use more register names (rather than hard-cases numbers).
3354 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3356 * Hack up 3.90.11 changes:
3358 * Makefile.dist (depend): parameterize $(GCC).
3359 Add solib.c and solib.o.
3360 (readline): Fix vpath for both absolute or relative SRCDIR.
3362 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3363 Also, let the part I didn't understand at least compile so
3364 I can test the rest. FIXME.
3366 * dbxread.c: Fix thinko using strcmp.
3367 (init_psymbol_list): declare static.
3368 (partial_symbol_file_open): Comment cleanups better, avoid
3369 cleaning up the string table since the caller will do that.
3370 Move the stat for mod time into symbol_file_command, temporarily.
3371 (There should be a mod time for each symbol file, eventually,
3372 to control its rereading. FIXME.)
3374 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3375 SunOS, which gives error for shared libs otherwise. (From
3376 Schaefer, probably FIXME needs work for portability.)
3378 * solib.c: Move #include "param.h" to work.
3379 Lowercase all the Uppercase Letters In the Messages.
3380 (find_solib): Clean up inferior_so_name for debug printouts.
3381 Allow no argument, to mean all shared libraries.
3383 * symmisc.c: include param.h to get CLEAR_SOLIB.
3385 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)

3428 (record_misc_function): Give correct type for N_DATA symbols.
3429 (condense_misc_bunches): do "misc_function_count = j" regardless
3431 Take code which is shared between symbol_file_command and
3432 add_file_command and put it into partial_symbol_file_{open,read}.
3433 Split add_file_command into add_file_command and add_file.
3434 Make psymtab_to_symtab read in the string table if the file
3436 Two new parameters to read_dbx_symtab and start_psymtab.
3437 tm-sunos.h: New file.
3439 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

3456 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3458 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3460 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3462 * tm-news.h: Add CALL_DUMMY_*.
3464 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.

3483 consistency with POSIX.
3485 * breakpoint.c (bpstat_stop_status): Disable watchpoint

3488 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
3490 * Makefile.dist: Bump version to 3.91.3.
3492 * Clean up handling of breakpoint commands (somewhat).
3493 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3495 inferior.h: Add breakpoint_proceeded to inferior status struct
3496 and globals; save it and restore it.
3497 (clear_breakpoint_commands): Cleanup, remove old #define.
3499 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3500 (save_inferior_status, restore_inferior_status): handle it also.
3501 (proceed): Remove earlier code that set breakpoint_proceeded.
3502 It is now set only in clear_proceed_status.
3503 (clear_proceed_status): Cleanup, use bpstat_clear rather
3504 than clear_breakpoint_commands. No callers need the stop_bpstat
3505 between clear_proceed_status and proceed.
3507 infcmd.c: Add breakpoint_proceeded definition and comment.
3508 (cont_command, jump_command, signal_command): Move call to
3509 clear_proceed_status right next to call to proceed.
3511 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3512 caller's argument while running down the chain of breakpoints.
3513 Use new variable "breakpoint_proceeded" to determine when
3514 a command that it executes moves the inferior past the
3516 (bpstat_clear): Handle NULL argument.
3517 (bpstat_clear_actions): Avoid useless call to
3518 breakpoint_auto_delete.
3519 (delete_breakpoint): Clean up bpstat's that are pointing to
3520 the deleted breakpoint from the stop_bpstat chain.
3521 (breakpoint_auto_delete): Simplify.
3523 * Clean up handling of EOF, error on stdin, etc. This was
3524 prompted by a network problem that caused gdb to go into an
3525 infinite loop filling up its malloc'd memory.
3527 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
3528 not clear_breakpoints_commands, which is now gone.
3529 (main): If command_loop returns (e.g. from EOF on stdin), do
3530 a quit_command (looping back to command_loop if quit_command
3531 doesn't really quit).
3532 (command_loop): check result from command_line_input and
3533 exit if it returns NULL, rather than passing the NULL to
3535 (gdb_readline): Free malloc'd result space before returning
3538 * utils.c (query): Handle C-d to mean "yes", just as if the
3539 input was not a terminal. Also avoid infinite loop if EOF
3540 occurs in mid-input-line before newline. This allows
3541 query to be used at EOF on stdin with reasonable results.
3543 * infrun.c (proceed): Set breakpoint_proceeded.
3545 * values.c (value_as_long): Avoid infinite recursion for enums.
3546 (_initialize_values): Fix typo in help msg (kingdon).
3548 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
3549 RL_LIB for linking. This allows -lreadline for linking
3550 and nothing for dependencies, once readline is a real library.
3552 * config.gdb: Jim Kingdon: give useful error message if the
3553 host or target type is not recognized.
3555 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
3556 it just defines it. Dumb, but deal with it.
3558 * Jim Kingdon suggests:
3559 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
3561 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
3563 * Makefile.dist (VERSION): Bump version # to 3.91.2.
3565 * Clean up Bothner's changes.
3567 * blockframe.c (clear_pc_function_cache): New function.
3568 * blockframe.c: remake cache_pc_function_* static.
3569 * dbxread.c (symbol_file_command): remove references to
3570 cache_pc_function_* variables.
3571 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
3572 * printcmd.c: Avoid kludging a global variable (addressprint)
3573 to avoid printing the address of a string twice. Instead,
3574 pass the format letter 's' down low enough that it can be seen
3575 to avoid this problem.
3576 (print_formatted): Pass format arg to value_print.
3577 (restore_addressprint): Remove function.
3578 (do_examine): Avoid hacking addressprint, cleanups and such.
3579 (print_frame_args): Add a comment to a Bothner change.
3580 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
3581 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
3582 to wipe out the values cached in blockframe.c.
3583 * symtab.c (find_method): Add comment saying how big you must
3584 allocate to be "big enough". Per being terse again.
3585 * valprint.c (val_print): Handle format letter "s" to print
3586 strings without addresses. Add comment to vtbl printing code
3587 which casts with wild abandon. Rearrange reference-printing
3589 @0xaddr: value (print w/addressprint)
3590 value (print w/~addressprint)
3591 @0xaddr (parameter lists w/addressprint)
3592 or nothing (parameter lists w/o addressprint)
3594 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
3596 * Merge more changes from Per Bothner:
3598 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
3599 annoying) that I tried to improve it. Here are my suggestions.
3601 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
3604 Do automatic de-reference when taking the address of a reference.
3606 Don't deref_ref when printing parameter lists.
3608 More attempts at treating refernences properly.
3610 In val_print, if deref_ref==0, don't print dangling " = ".
3612 Add COERCE_REF macro, which de-references an REF.
3614 * Merge changes from Per Bothner:
3616 * Fixed (Sony news)-specific configuration problems.
3617 * Fixed other problems with using vanilla pcc and libc (enum problems;
3618 assumption that vsprintf exists).
3619 * Some major speed-ups (finc_pc_partial_function now caches a match;
3620 parsing avoids duplicate symbol_lookup calls).
3621 * Changed handling of baseclasses (no longer use baseclasses field
3622 of struct type, use the first n_baseclasses fields instead).
3623 * Various minor changes/fixes, most C++-related.
3626 Cache the most previous match from find_pc_partial_function.
3627 (Save both low and high ends of matching function's pc range.)
3628 This speeds up the loop of infrun.c:wait_for_inferior quite
3629 a bit, and makes step/next commands much zippier.
3631 Added an enum->int cast (otherwise, some compilers barf).
3633 No longer set baseclass offset to 0, since multiple
3634 inheritance now mostly works.
3635 Added a number of casts, to shut up compiler warnings
3636 (after stabs where made enums, not ints).
3637 When discarding a symbol table (in symbol_file_command),
3638 must clear the cache introduced in blockframe.c.
3639 Don't convert $vtbl_ptr_type to vtbl any more.
3640 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
3641 Mask off sign bit emitted by g++ for virtual table offset.
3642 Set voffset to -1 (not 1) for static member functions.
3644 Changed parsing/lexing of names to avoid doing symbol lookup twice
3645 (once when lexing to determine symbol class, once for real).
3646 Now only call symbol_lookup once. Fields of 'this' win especially big.
3648 Subpress printing addr twice in the case of 'x/s addr'.
3650 lookup_basetype_type is no longer used.
3651 Add find_methods as recursive helper function to decode_line_1.
3652 This allows multiple inheritance to work.
3653 Also, once one or more matches has been found, do not look in
3654 base-classes. (Baseclass methods would be overridden, anyway.)
3656 Removed baseclasses array in struct type.
3657 Instead of using baseclasses[i], use fields[i-1].
3658 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
3659 Changed sign convention of voffset (previous was inconsistent).
3661 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
3663 Used to assume existence of vsprintf. Re-written to not need it
3664 if HAVE_VPRINTF is undefined.
3666 typecmp was too pessimistic. Made it less so.
3668 Don't print space after address.
3669 If vtable points to a misc symbol (with 0 offset), print it,
3670 since that indicates the actual class of the object.
3671 Changed ype_print_derivation_info to use new inheritance
3672 scheme (without baseclasses vector).
3674 In value_primitive_field, fixed some bugs left over from previous set of fixes.
3675 Also, changes needed because TYPE_BASECLASSES were removed.
3677 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
3679 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
3682 If there is no path set, and the symbols don't indicate what directory
3683 a file was compiled in, look in the current directory. But either
3684 a path or a known compilation directory will prevent this.
3687 Three independent bug fixes:
3688 * Remove the #if 0 block that breaks some stuff.
3689 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
3690 adapt gdb to either SunOS 4.0.* or 4.1.
3691 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
3694 Instantiate the class T when looking for methods in it. (Tiemann@sun)
3697 (type_print) Demangle the name being printed.
3698 (type_print_base) Handle botched demangling without coredump (tiemann).
3701 (check_stub_method): Document routine.
3702 (tiemann) fix bug for no-arg functions
3703 Avoid clobbering beyond end of malloc'd storage.
3704 Terminate the argument list properly.
3706 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
3708 * Changes merged by John Gilmore:
3711 In breakpoint_1, use new print_address_symbolic instead
3712 of find_pc_partial_function. (This forces use of assembler-level
3713 addresses, and avoids misleading non-mangled source-level names.)
3715 Generalize ansi argument such that -1 means skip arglist totally.
3716 Removed global variable print_ansi_qualifiers (which made
3717 code non-reentrant), in favor of extra explicit arguments
3718 to internal routines.
3720 Add new helper function print_address_symbolic.
3721 Use find_pc_misc_function instead of find_pc_partial_function
3722 (since we want assembler-level symbols here).
3724 Print unknown function as just "f (...)", not "f (...) (...)".
3725 Use new fputs_demangled explicitly.
3727 Fixed a typing violation (problem: value.h cannot be imported
3728 without renaming many variable in this file).
3729 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
3730 decode_line_1: Moved forward some never-reached code.
3731 Made decode_line_2 skip function prologues correctly.
3733 fputs_filtered should not demangle by default.
3734 Add new fputs_demangled to demangle on demand..
3736 Change value_struct_elt to use value_primitive_field (using recursive
3737 utility function search_struct_field). This allows foo.bar to work
3738 for multiple inheritance (so far only for data fields).
3739 Change check_field in the same way (recursive helper function
3740 to support multiple inheritance).
3741 (Note: there are more of these problems that I haven't fixed.
3742 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
3743 value_of_this: 'this' symbol name is now just "this", note "$this".
3745 Don't print static members.
3746 Avoid printing "members of <type>" if there are none.
3747 Simplified type_print_derivation_info by merging duplicate code.
3748 Remove useless blank lines in type_print_base (ptype command).
3750 Added declaration of new routine value_primitive_field.
3752 Added value_primitive_field which is generalized version of
3753 value_field that can handle multiple inheritance (non-zero offsets etc).
3754 Re-implemented value_field to call value_primitive_field.
3756 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
3758 * infcmd.c -- insert else to avoid 'delete env' coredump when you
3759 delete the whole environment. Karl Berry reported the bug.
3760 * source.c - fix openp to avoid //'s in filenames, which
3761 trigger an Emacs bug causing it to not be able to find files
3762 when running gdb in a window.
3763 * dbxread.c - zap the #if 0 that botches the add-file code.
3764 It seems to work a lot better without all the code commented out.
3766 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
3768 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
3771 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
3773 * Makefile - added a ${CFLAGS} to a couple of entries,
3774 added remote-sa.sparc.c
3775 * added remote.sa-sparc.c, a modification of remote.c
3776 which conducts a dialog directly with the SparcStation prom.
3777 * breakpoint.c, infrun.c, sparcdep.c added
3778 remote_insert_breakpoint(), and remote_remove_breakpoint()
3779 to breakpoint.c instead of directly writing breakpoint instructions.
3780 * sparcdep.c on remote_debugging,there is no need
3781 to remove signle step breakpoint instructions.
3782 * main.c added "-epoch" flag and "int epoch_interface" to main.c
3784 * printcmd.c - epoch interface sends lisp expressions to open up
3785 epoch windows on inspection.
3786 * valprint.c - added arrayprint, and addressprint and made adding
3787 format controls easier
3788 * wait.h added a couple of undef's because we were getting
3789 complaints about WSTOPSIG and WTERMSIG begin redefined.
3792 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
3794 * symtab.c (decode_line_1): Add support for handling method stubs

3799 * values.c (baseclass_addr): Run loop from INDEX+1 to
3800 N_BASECLASSES; otherwise, we can still get into a loop.
3801 @@ This should be restructured to use a cleaner search strategy.
3803 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
3805 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
3806 abbreviation "Tt" for tags which have the same name as their
3809 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
3811 * symtab.c (list_symbols): add ability to set breakpoints on all
3812 the functions which match a particular regular expression.
3814 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
3816 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
3817 should print ANSI qualifiers (such as `const' and `volatile').
3818 All callers changed to call with ANSI == 1, except from
3819 `check_method_stub', which uses old-style syntax.
3821 * symseg.h (struct fn_field): Remove unneccessary `args' field.
3822 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
3824 * values.c (check_stub_method): New function.
3826 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
3828 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
3829 * valprint (type_print_base): Ditto.
3831 * symtab.c (gdb_mangle_typename): New function.
3833 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
3835 * breakpoint.c (catch_command): New function. Provides a
3836 mechanism to set breakpoints based on catch clauses.
3837 (disable_catch): Similar, but disables breakpoints on catch
3839 (delete_catch): Similar, but deleted breakpoints on catch clauses.
3841 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
3843 * blockframe.c (blockvector_for_pc): New function.
3844 * blockframe.c (block_for_pc): Changed to call
3845 `blockvector_for_pc' and get the block itself.
3847 * stack.c (catch_info): New function. Prints info about
3848 exceptions which can be caught in the current frame.
3849 * stack.c (print_frame_label_vars): New function. Similar to
3850 `print_frame_local_vars'.
3851 * stack.c (print_block_frame_labels): Prints out labels that are
3852 defined in this frame. These labels are exceptions that can be
3855 * dbxread.c: Updated to handle N_CATCH symtab types.
3857 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
3859 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
3860 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
3861 when printing the type.
3863 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
3865 * valprint.c (val_print): Use `baseclass_addr' to access the
3866 baseclasses pointed to via the derived class object at VALADDR.
3868 * values.c (baseclass_addr): New function. Casts derived pointers
3869 to baseclass pointers taking virtual baseclasses and multiple
3870 inheritance into account.
3872 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3876 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3878 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
3879 exp_valid_block field correctly.
3881 * infrun.c (wait_for_inferior): When checking "don't even think
3882 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
3883 also check step_resume_breakpoint.
3884 Insert breakpoints and continue (not step) if
3885 step_resume_break_address != NULL, even if another_trap.
3886 If trap_expected and we enter sigtramp, then set up a
3888 If trap_expected is set when we hit the step_resume_break,
3890 When calling resume and trap_expected says tell resume to step
3891 (2 places), also check step_resume_break_address.
3893 * infrun.c (wait_for_inferior): Don't set
3894 prev_{pc,sp,func_{start,name}} before calling wait ().
3895 Do set them after exiting loop.

3901 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
3902 Restore old code which distinguishes between trap_expected and
3903 running_in_shell, just make the latter take any non-TRAP signal,
3906 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
3908 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.

3933 char. Add macro VALUE_OPTIMIZED_OUT.
3935 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
3936 instead of stuffing things in buffers (oappend, etc).

3968 findvar.c (get_saved_register): New function.
3969 findvar.c: Rewrite code which called find_saved_register to
3970 call get_saved_register instead.
3972 Sun Apr 22 14:47:51 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

4008 * coffread.c: Define L_LNNO32 if not defined.
4009 (enter_linenos): Use it.
4010 * blockframe.c: Add INIT_FRAME_PC hook and use it in
4011 get_prev_frame_info.
4012 m-m88k.h: Use INIT_{FRAME_PC,EXTRA_FRAME_INFO} to do tdesc stuff.
4013 Use dummy versions of FRAME_CHAIN_*.
