596 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
598 Permit symbols to be superseded when new symbol files have
599 been read in, particularly for VxWorks.
601 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
602 to the main file, as well as to include files. Also, put global
603 functions into the global psymtab, to make "i fun" work.
604 (end_psymtab): Free named symtabs and psymtabs for a file, once a
605 new psymtab for it has been read.
606 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
607 a file, once a new symtab has been read for it.
608 * mipsread.c: FIXME. We need to do the same for MIPS, but it
609 looks harder to determine the top-level block before it's been
610 queued to the psymtab list.
612 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
613 If we have wiped out any old symbol tables, clean up at end of
615 (symbol_file_command): Don't reference symfile_fns if it's zero.
617 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
618 defines for the blocks of a blockvector that contain global and
619 file-static symbols and the first of the smaller scope contours.
620 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
621 decode_line_1, make_symbol_completion_list): Use the above.
622 * coffread.c (end_symtab, patch_opaque_types): Ditto.

628 * symtab.c (list_symbols): Process the first symbol of the
629 static psymbols list.
630 (types_info): Restore this function from its untimely #if 0.
631 It's not perfect, but it is better than nothing.
632 (_initialize_symtab): Restore "info types".
634 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
636 * m68k-stub.c: Remote stub for 680x0's, created from
637 rem-m68k.shar (which is removed).
638 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
639 Remove RCS log stuff now that we use CVS and it blows our diffs.
641 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
643 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
644 * symfile.c (clear_symtab_users_once, cashier_psymtab,
645 free_named_symtabs): Move these routines from symmisc.c.
646 (free_symtab): Make non-static.

650 (initialize_dbxread): Call dbx_new_init() in case the first
651 command is add-symbols.
652 * target.c (dummy_target): Permit add_syms_addr_command.
654 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
656 Permit symbols to be superseded when new symbol files have
657 been read in, particularly for VxWorks.
659 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
660 to the main file, as well as to include files. Also, put global
661 functions into the global psymtab, to make "i fun" work.
662 (end_psymtab): Free named symtabs and psymtabs for a file, once a
663 new psymtab for it has been read.
664 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
665 a file, once a new symtab has been read for it.
666 * mipsread.c: FIXME. We need to do the same for MIPS, but it
667 looks harder to determine the top-level block before it's been
668 queued to the psymtab list.
670 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
671 If we have wiped out any old symbol tables, clean up at end of
673 (symbol_file_command): Don't reference symfile_fns if it's zero.
675 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
676 defines for the blocks of a blockvector that contain global and
677 file-static symbols and the first of the smaller scope contours.
678 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
679 decode_line_1, make_symbol_completion_list): Use the above.
680 * coffread.c (end_symtab, patch_opaque_types): Ditto.

688 (types_info): Restore this function from its untimely #if 0.
689 It's not perfect, but it is better than nothing.
690 (_initialize_symtab): Restore "info types".
692 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
694 * m68k-stub.c: Remote stub for 680x0's, created from
695 rem-m68k.shar (which is removed).
696 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
697 Remove RCS log stuff now that we use CVS and it blows our diffs.
699 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
701 * symmisc.c (free_named_symtab): Make it work, in its current
702 kludgy fashion. Change result to indicate if we blew away bkpts.
703 * dbxread.c (end_symtab): Accumulate result from
704 free_named_symtab and print warning if we blew user's state.
705 * symfile.h: free_named_symtab now returns an int.
707 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
709 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
710 is the first symbol read, even if not mainline.
711 (dbx_psymtab_to_symtab): symfile might be zero, cope.
712 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
713 (set_section_command): New command ("section xxx yyy" -- should
714 be renamed to "set section xxx yyy" FIXME) which sets the
715 base address of a section of the exec file, overriding the
716 virtual address that BFD reports.
718 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
720 * exec.c: Add add_syms_addr_command to exec_ops, so you can
721 load symbols at any address while examining an exec file.
723 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
725 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
726 for printing the float info is host-dependent, not
727 target-dependent. FIXME.
728 * i386-pinsn.c: Move #includes to top, remove useless ones.
729 * i386-tdep.c: Don't bother including <.../reg.h> since we
730 don't use it (and it doesn't exist on host systems).
732 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
733 Convert negative numbers properly.
734 (ieee_test): Make numbers really random; fix format arg.
736 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
737 * core.c (core_detach): Unpush core_ops, which might not be on
738 top. We used to just pop the top, which broke things. Don't
739 need dont_repeat() any more.
740 (core_file_command): Psst! Don't repeat it.
741 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
742 * expprint.c (print_subexp): Avoid switch fallthru on
743 BINOP_ASSIGN_MODIFY, so we can print += and such.
745 * inflow.c (kill_command): After killing inferior, print our
746 current frame in the core file, if we have one.
747 (generic_mourn_inferior): When inferior dies, either select
748 the current frame (in the new target, e.g. core file), or
749 set both the current and selected frames to NULL.
751 Changes from Peter Schauer.
753 * infptrace.c: Avoid <sys/ptrace.h> on USG.
755 * Make all file names fit in 14 characters (sigh and damn!):
756 mv hp300hpux-xdep.c hp300ux-xdep.c
757 mv symmetry-xdep.c symm-xdep.c
758 mv symmetry-tdep.c symm-tdep.c
759 mv convex-opcode.h convx-opcode.h
760 mv tm-vxworks960.h tm-vx960.h
761 mv tm-vxworks68.h tm-vx68.h
762 mv Makefile.srcdir Makefile.sdir
763 mv gdb-int.texinfo gdbint.texinfo
764 mv remote-sa.m68k.shar rem-m68k.shar
765 mv remote-multi.shar rem-multi.shar
766 * Makefile.dist, README, config.gdb, convex-pinsn.c,
767 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
768 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
771 * command.c (user_info_1, user_info): New command for listing
772 the user-defined commands.
774 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
776 * dbxread.c (really_free_pendings): Clear file_symbols
777 and global_symbols after freeing them; otherwise, running
778 this function twice (if it appears twice on the cleanup
779 chain), we try to free things twice.
781 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
782 based on text_addr (the address of text in core), not on addr (the
783 offset between text in the .o file and in core). This change
784 is from Peter Schauer.
786 * main.c: Define ALL_CLEANUPS as a cast of zero.
787 (return_to_top_level): Use it.
788 (main): Do all cleanups after each command run as part
789 of the gdb startup sequence. Also do all cleanups before
790 entering the command loop, and every time we exit the command
791 loop and reenter. Before, the cleanups from the startup sequence
792 were being left undone until the first error!
793 (command_loop): Rename do_nothing cleanup to command_loop_marker
794 so we can see it easily when examining the cleanup chain.
795 (init_signals): Add another do_nothing for signal handling.
796 (quit_command): Only try to kill target if it has execution.
797 Problems in the target stack got us into a state where
798 inferior_pid was nonzero but none of the targets had execution.
799 In this state you couldn't exit gdb.
801 * dbxread.c: Two changes from Peter Schauer.
802 (echo_command): Fflush output after an echo command.
803 (show_history): Pass all args to cmd_show_list.
805 * utils.c (init_malloc): Call mtrace to turn on tracing
806 if the environment variable MALLOC_TRACE is set to a file name.
807 * mtrace.c: Add source file which provides a log of every malloc,
808 free, and realloc to a trace file.
809 * mtrace.awk: Add source file which analyzes the trace file.
810 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
811 (VERSION): Roll to 3.94.3.
813 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
814 (check_duplicates): Don't bother with watchpoints.
815 (set_raw_breakpoint): Comment about danger of this routine.
816 (watch_command): Parse and eval all args before calling
819 * solib.c (find_solib): Avoid error in referencing memory to
820 see if any more shared libraries have been added. This is
821 particularly useful if the target has terminated. Bug reported
825 in bringing up 3.94.2 on the Sun-3.
827 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
828 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
829 expression (in scope) before reenabling watchpoint.
830 * signame.c (init_sigs): Add missing declaration of i, fix
831 sys_siglist declaration.
832 * source.c (list_command): Fixed range computation to use
834 * stack.c (backtrace_command): Do not allow command if target has
835 no stack, print informative error message.
836 * target.c (target_command): Do not write into command line
837 because this fails if the target command is used in a user defined
838 command. [This change was enhanced by gnu to support any-
839 unique-prefix matching on target names.]
840 * valops.c (value_struct_elt): Avoid infinite loop on an
841 erroneous attempt to print the member of function (try p main.p).
843 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
845 * expread.y (name_no_typename): Avoid reduce/reduce errors
846 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
847 Since the GDB parser really doesn't use name_no_typename in a
848 name-only context, the parser can't tell the diff between
849 names and numbers here. Avoid allowing a name_no_typename
850 to be a NAME_OR_*INT to resolve the conflict.
852 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
856 * valprint.c (val_print_fields): bitfield printing didn't handle
857 byte order. Indirect through a few more fns to cope.
859 * values.c (modify_field): also cope with byte order.
861 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
863 Cleanup for release 3.94.2:
865 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
866 include files. Roll version to 3.94.2.
868 * coffread.c (init_stringtab): Read length into unsigned char
869 array before swapping; don't assume 32-bit longs.
871 * target.c (target_info): Don't bother with get_sym_file, just use
872 the symfile global variable.
873 * symtab.h, symfile.c (get_sym_file): Delete it.
875 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
876 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
877 (read_type): Replace one more error() with complain().
879 * mipsread.c (parse_partial_symbols): Replace printf with complain.
881 * i960-tdep.c: Fix copyright attribution.
883 * config.gdb: Quote all backquotes in doublequotes. You can
884 quote me on that. BSD 4.4 shell found this one.
886 * infptrace.c (throughout): The third argument to ptrace is an
889 * infrun.c (wait_for_inferior): When program has terminated, we
890 have to call target_terminal_ours before we pop that target off
891 the stack (e.g. before a call to target_kill or
892 target_mourn_inferior). This fixes problem where a program
893 terminates, then GDB stops for (tty output) and you have to type
894 "fg" to the shell to resume it. FIXME: This code for what to
895 do after termination really should be in normal_stop instead.
897 * gdbcore.h (read_memory_check): Change declaration; it changed
900 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
901 4.4 prereleases, this avoids a bug in their sgtty compatability
903 * remote.c: Use terminal.h rather than hand-rolling the same.
905 * signame.c, signame.h (psignal): Arg is unsigned, not int.
906 * utils.c (strsave, strstr): Fix arg types.
907 * valprint.c (val_print): lint
909 MIPS symbol table support from Per Bothner:
911 * symfile.c (symtab_fns): Remove initializer table that needs to
912 be hacked for each new symbol file format supported.
913 (add_symtab_fns): New function, chains symbol table
914 handlers into the global list.
915 (symfile_init): Search this list.
916 * symfile.h: Add next pointer, declare add_symtab_fns.
917 * coffread.c (_initialize_coffread): Call add_symtab_fns.
918 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
920 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
921 symbol *). Thus, we no longer need the hack to trash
922 pst->filename. Good, since that hack confused code in symfile.c!
924 (reorder_symtabs, destroy_all_symtabs): Removed static
925 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
926 Instead, the latter now uses a temporary array (stack-allocated
927 from an obstack, and then freed).
929 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
930 haven't been set in the outermost stBlock of a procedure. This was
931 a problem with f77 binaries on Ultrix 4.?.
933 (new_symtab, new_symbol, new_type): Continue changing code to use
934 obstacks more and otherwise conform to dbxread internal style.
935 Made the free_code of symtabs be free_linetable (as in dbxread)
936 instead of free_contents. This implies memory leaks when reading
937 a new symbol table, until the conversion is finished. Did change
938 (struct symbol) and (struct type) to be allocated on the
939 symbol_obstack. Blocks and blockvectors are among the things
942 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
943 tested much, but it solved one problem (reported by Meissner), and
944 cleans up some other things. The problem happened when an
945 included file contains actual code (functions) and not just
946 definitions. The mips coff is a little inconvenient there, since
947 it may cause a procedure to be mapped to the wrong psymtab.
949 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
950 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
951 this will need work for the new core paradigm.
953 Opcode patches from the net:
955 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
956 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
957 missing altogether - they are added here. From Bruce Bauman.
958 * mips-opcode.h: The low mask for C0 instructions was too small.
959 From Garrett Lau. I modified the fix to check the entire 32-bit
962 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
965 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
967 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
969 * dbxread.c (read_type): Pointer subtraction (value_sub in
970 valarith.c) sometimes failed because the types of the
971 pointers being subtracted were not identical.
972 These differed because dbxread.c was allocating pointer types
973 using dbx_alloc_type+smash_to_pointer_type instead of
974 lookup_pointer_type. I failed to find a justification for the
975 former, so I changed it to use the latter. Similarly, I
976 replaced smash_to_function_type by lookup_function_type,
977 and smash_to_reference_type by lookup_reference_type.
979 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
980 _initialize_mipsread): corresponding changes.
982 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
984 * source.c (mod_path): Do tilde_expand on each component of the path,
985 rather than on the (list of) paths as a whole.
986 (print_source_lines): Set first_line_listed in addition to
987 current_source_symtab and current_source_line. If the source was
988 not findable, after a "dir" command to fix the problem,
989 a "list" would get the wrong lines.
991 While I was there... (gnu):
993 * dbxread.c (read_type): Change error to complaint.

1003 (): FIXME: Should realloc-down the psymbol lists when done reading
1004 the main symbol file?
1006 * symmisc.c (free_symtab): Free fullname field too.
1008 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1009 (REGISTER_ADDR): Make result type unsigned int.
1011 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1012 define REGEX must also define REGEX1 (its dependency).
1014 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1016 * tconfig/i960: No longer works, points you at vxworks960 or

1033 (object search path) as conveniently as the source search path.
1034 * environ.c (set_in_environ): Set some vars in GDB's environment,
1035 in addition to the child's. PATH, G960BASE, G960BIN for starters.

1042 (printchar): Use it.
1043 (strsave): Provide this handy helper routine.
1044 (set_width_command): Rename set_screen_width_command.
1045 (_initialize_utils): "set screen-width" => "set width";
1046 "set screen-height" => "set height"; add sevenbit-strings.
1048 * infcmd.c (do_registers_info): Print floating point registers
1049 in raw hex as well as float format, regardless of whether it is
1050 a "virtual" convertible register.
1051 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1052 regs as a double, just in case it's being used that way.
1053 * values.c (unpack_long): Comment on array/function coercion.
1054 (unpack_double): Argument is in target byte order now. For
1055 integer arguments, just call unpack_long and float the result.
1056 * m68k-tdep.c: include defs.h for "const" handling.
1057 * remote-nindy.c: Use ieee-float stuff.
1058 (nindy_fetch_registers): Unpack double regs to host double, then
1060 (nindy_store_registers): Pack extendeds to host double, flip
1061 around by misusing unpack_double, send as target double.

1070 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1072 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1074 * coredep.c (fetch_core_registers): Pass end-address of register
1075 section to register_addr as expected. Don't call supply_register
1076 if we'd just pass it garbage.
1078 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1080 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.

1125 * inftarg.c (child_detach): Pop the child_ops vector if the
1126 detach is successful.
1127 * remote-nindy.c (nindy_create_inferior): Don't push a new
1128 nindy_ops since nindy uses the same one for execution and memory
1130 * core.c (core_ops): Use child_attach and child_create_inferior
1131 rather than default attach and create_inferior functions.
1133 Handle floating point registers in core files.
1135 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1136 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1137 This version untested since BFD doesn't yet support sun3 core
1139 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1140 conventions. Fix comments and style. This version has not
1141 been compiled yet, since we have no HP inhouse.
1142 * core.c (get_core_registers): Look for two sections, ".reg"
1143 and ".reg2", and pass both to fetch_core_registers sequentially.
1145 Revise directory path yet again.
1147 * source.c (forget_cached_source_info): Not static any more.
1148 (init_source_path): New default source path is "$cdir:$cwd".
1149 (dir_command): Handle variable arguments ($cdir, $cwd).
1150 (source_info): Print "Compilation directory" rather than
1151 "Originally compiled in" to remind people of $cdir.
1152 (openp): If the path contains $cwd, use current directory.
1153 (open_source_file): If compilation directory is known, replace
1154 first $cdir in path with the compilation directory.
1155 (print_source_lines): Even if we can't print the lines, set the
1156 current symtab and line for future commands like "info source" or
1157 "breakpoint". Also, error message now contains the file name,
1158 line number, and file access error message.
1159 (_initialize_source): Fix help text to describe changes.
1160 * main.c (cd_command): Forget cached source info when we chdir.

1165 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1166 Byte-swap COFF symbol tables if necessary when reading them in.
1167 Use complain() to replace error message in one spot. Needs
1168 corresponding change in bfd/coff-code.h to make some symbol
1169 swapping routines non-static.
1171 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)

1181 declarations of errno.
1183 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1185 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1186 <rpc/rpc.h> and <rpc/types.h>.
1188 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1190 * i960-tdep.c (examine_prologue): Add new argument limit,
1191 which stops the scan at the end of the prologue, or at the PC.
1192 This fixes a problem where it walks down into the code for the
1193 user's statements if that code looks like function prologues.
1194 Mark Fox and I have been bouncing this code back and forth, making
1195 small changes to it. Callers changed to match.
1197 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1199 Cleanup for gdb-3.94 release final:
1201 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1202 the .c files from vx-share and nindy-share, from the various
1203 macros, since they are not found via ALLDEPFILES.
1204 (SFILES): Add tm-i960.h.
1205 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1206 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files

1213 * am29k-tdep.c: Add contribution line.
1214 (examine_prologue): Cache information about function prologues in
1215 the misc-function-vector to avoid lots of references over the
1216 serial line while examining instructions.
1218 * core.c (core_close): New function made from cleanup_core.
1220 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1221 remote-vx.c, remote.c, target.c, target.h,
1222 Update target_ops vector to add attach, close, and load entries.
1223 Use add_syms_addr_command, not add_file_addr_command, for
1224 add_file. Break out close routine from existing code.
1226 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1227 they are in an obstack.
1228 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1230 (define_symbol): Add symbol type parameter; change callers;
1231 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1232 it to influence the symbol class on the i960.
1233 (define_symbol): Swap LOC_CONST's into target byte order.
1235 * exec.c (exec_close): New function.
1236 (exec_file_command): Call it.
1238 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1239 Fix byte order of frame pointer.
1240 (read_var_value): Result of 0 if var's value can't be found,
1241 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1242 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1243 (locate_var_value): Use read_var_value and use its lazy address
1244 as the location of the var's value. Lint.
1246 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1249 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1250 obsolete Intel versions in favor of vxgdb versions.
1251 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1252 code dealing with byte order of values, which Intel did in host byte
1253 order rather than gdb-4's target byte order.
1254 (i960_frame_chain_valid): Move to nindy-tdep.c.
1255 (examine_prologue, skip_prologue, frame_find_saved_regs,
1256 frame_args_address, leafproc_return, saved_pc_after_call,
1257 pop_frame): Add vxgdb versions from Mark Fox.
1258 (examine_prologue, frame_struct_result_address): Add code
1259 to deal with the saved value of G13 (struct return address
1261 (frame_args_address): Modify Mark's version to prefer the
1262 saved value over the current value in the topmost frame.
1263 Cache result in the frame info to avoid performance hair in
1265 (print_fault): Add gdb960 code for printing faults.
1266 (_initialize_i960): Actually call check_host.
1268 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1269 add stub routines. FIXME, these currently just return zero!

1274 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1275 (child_attach): Rename from child_open.
1276 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1277 don't confuse it with a zero step_resume_break_address.
1279 * inftarg.c (child_detach): Eliminate inferior_pid test.
1280 (child_files_info): Clean up message a bit.
1281 (child_ops): Use child_attach, not child_open, to attach.
1283 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1284 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1285 findvar.c to here, since it depends on the contents of the
1286 shadow_contents of breakpoints, but keep if #if 0 since it is
1289 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1292 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1293 (ptype_command, display_command): Eliminate have_inferior_p and
1294 have_core_file_p in favor of target_has_stack or
1295 target_has_execution.
1296 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1297 code for actually finding the values of arguments, though we still
1298 keep track of the maximum stack offset for use in printing unnamed
1299 arguments. Handle missing FRAME_ARGS_ADDRESS.
1301 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1302 (struct nindy_regs): Define registers passed to/from nindy.
1303 (nindy_fetch_registers, nindy_store-registers): Translate between
1304 nindy and GDB formats for the registers.
1305 (dcache_init): Statically allocate the cache, since it was being
1306 allocated by a malloc that was never freed anyway.
1307 (nindy_create_inferior): Error, not core dump, if no exec file.
1308 (nindy_before_main_loop): Use target_load, not target_add_file.
1310 * remote-vx.c (net_load): Specify large timeout for load
1311 requests. Allow user to break out with INTERRUPT.
1312 (net_break): Remove useless code, clean up. Change callers.
1313 (parse-args, skip_white_space, find_white_space): Clean up arg
1314 parsing to cope with quoted strings.
1315 (net_wait, net_quit): Never call error, just return status.
1316 (vx_read_register, vx_write_register): Cleanup status checking.
1317 #ifdef the code based on which CPU we are using (960 or 68k),
1318 FIXME, this should be completely general but it isn't yet.
1319 (vx_xfer_memory, vx_resume): Cleanup status checking.
1320 (vx_run_files_info): Improve message.
1321 (vx_load_command): Renamed from vx_add_file_command. Allow load
1323 (net_ptrace): Remove unused routine.
1324 (vx_wait): Adopt code from vxgdb960 to cope with broken
1325 connections to target machine and prompt to disconnect. Remove
1326 debug printouts. Map some EVENT_'s to SIGnals.
1327 (add_symbol_stub, vx_open): Print names of object files we found,
1328 and "ok" if we read their symbols OK. Clarify output in general.
1329 (vx_attach, vx_detach, vx_kill): Add these commands.
1330 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1331 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1332 "info files" output, and create_inferior, since we already have
1335 * stack.c (frame_info): Replace Frame_unknown with 0.
1336 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1337 (return_command): Pop until the PC matches as well as the FP,
1338 so it works even if the FP is shared with another function,
1339 as in "frameless" or "leaf" procedures.
1341 * symfile.c (load_command): renamed from add_file_target_command.
1342 (add_syms_addr_command): renamed from add_file_addr_command.
1343 (add_syms_command): Stub to call target_add_syms.
1344 (_initialize_symfile): Change command names and descriptions,
1345 add-file => add-syms, and load from alias to its own command.
1347 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1348 maybe_kill_then_create_inferior): Default for attempts to start
1349 a process, if one is already running, is to ask about killing
1350 it and retry if yes.
1351 (upstack_create_inferior): #if-0 it, strata obsolete it.
1352 (push_target, unpush_target, pop_target): to_close() a target
1353 before unstacking it.
1354 (target_info): Renamed from target_files_info.
1355 (_initialize_targets): Rename "i files" as "i target", accessible
1358 * target.h: Improve comments about the target_ vectored routines.
1360 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.

1363 (SKIP_PROLOGUE): No longer a no-op.
1364 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.

1366 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1367 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1368 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1369 are now 10 byte extendeds, not 8 byte doubles.
1370 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1371 for nindy versus vxworks targets. FIXME, this should possibly go
1372 in the target vector.
1373 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1374 frame_saved_regs and arg pointer with each frame.
1375 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1376 (FRAME_ARGS_ADDRESS): Use cached result.
1377 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1378 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1379 (PRINT_RAMDON_SIGNAL): Call print_fault.
1380 (POP_FRAME): Now works.
1382 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1383 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1384 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1385 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1388 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1389 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1391 * valarith.c (value_subscripted_rvalue): Avoid handling
1392 floats and doubles specially; it gave alignment errors. Lint.
1394 * valops.c (value_of_variable, value_of_this): Error if unknown
1397 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1398 to avoid alignment problems.

1401 (val_print): Use unpack_long rather than pointer-deref.
1404 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1405 to avoid alignment problems.
1406 (value_being_returned): Error if return value unknown.
1407 (set_return_value): Add bogosity warning, FIXME. *
1409 * TODO: A woman's work is never done.
1411 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1412 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1413 Add ieee-float.o to OBS.
1414 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1415 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1416 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1418 Changes to generalize the VxWorks RPC protocol slightly, to handle
1419 i960 as well as 68000.
1421 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1422 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1423 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1424 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1425 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1426 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1427 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1428 so they will move in target byte order rather than network
1429 byte order (happens to be the same).
1431 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1433 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1435 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1438 Add contribution lines to various files, showing where they
1441 * breakpoint.c (break_insn, check_break_insn_size,
1442 read_memory_nobpt): Remove to mem-break.c.
1444 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1447 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1448 entry has bad register number. This change is not
1449 tested in this release, FIXME.
1451 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1454 * value.h: Force value's contents field to be aligned to hold
1455 at least a double or a long long (if supported). This avoids
1456 doing bcopy's in and out of the contents field.
1458 (step_1): Avoid coredump under obscure circumstances when we
1461 * symtab.h (misc_info): Add field to misc function vector for
1462 any kind of cached information the target code desires. AMD
1463 29000 uses this to avoid repeating examine_function_prologue's.
1465 * coffread.c: Lint. Remove static symfile, read_section_header.
1466 core.c (have_core_file_p): Lint: remove.
1467 expprint.c (print_subexp): Lint.
1468 infptrace.c, valops.c, valprint.c: lint.
1470 Roll in changes from vxgdb-5.0.1:
1472 * symtab.h: Comment byte order of each address class. Add
1473 LOC_LOCAL_ARG for frame-relative args (960).
1474 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1475 symtab.c, symmisc.c: ditto.
1477 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1479 * remote.c (remote_resume): Error if resume with a signal.
1481 * symfile.c (prim_record_misc_function): Clear misc_info.
1482 (fill_in_vptr_fieldno): Check stub type of arg.
1484 * valops.c (value_cast): Avoid looking up names of types whose
1485 name we don't know, to prevent coredump. Sun CC produces typedef
1486 rtx and the name of *rtx is zero...
1488 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1490 Roll in changes from final AMD 29000 port (Tiemann).
1492 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
1493 for ../include/a.out.encap.h. This might not work now that BFD
1494 is separately compiled. Instead, BFD support for encap will have
1495 to translate machine type 29k into the right COFF_MAGIC.
1497 * infcmd.c: Remove references to inferior_pid that aren't used
1498 in actual ptrace calls; use target_has_execution, etc.
1499 (have_inferior_p): Remove function.
1500 (program_info): Print target info rather than "process number";
1501 avoid gratuitous messages unless from_tty.
1502 (run_stack_dummy, finish_command): Set proceed_to_finish.
1503 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
1504 main.c: Lint. Lose have_inferior_p().
1505 inferior.h (have_inferior_p): Remove, lint.
1506 (proceed_to_finish): Add flag to ask that all regs be saved
1507 by normal_stop, for the few commands that need it, speeding up
1508 serial I/O. Add comments to stop_registers.
1510 * remote-eb.c: Remove newline from breakpoint message we grep
1511 for. Never time out when running the user program.
1515 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1517 Roll in changes from vxgdb-5.0.1:
1519 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
1520 symbol in its raw form, we are processing an unlinked ".o" file.
1521 See if the target environment has assigned it an address, using
1522 target_lookup_symbol (VxWorks does), and enter it into the symtab
1525 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
1526 68k versions for a simpler version that assumes zero FP at bottom.
1527 Fixes bug of truncated stack reports.
1529 * target.h (target_lookup_symbol): Define this routine's args
1530 and result, finally.
1532 * target.c (nosymbol): Default routine for target_lookup_symbol.
1533 (target_default): Default lookup_symbol and call_function too.
1534 (files_info): Only print has_all_memory warning if a non-dummy
1537 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
1538 vx_convert_from_virtual): If target does not have floating point,
1539 zero register "values", and avoid doing cross-net conversions.
1540 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
1541 (vx_open): Rearrange code that attaches to target and reads
1542 symbols for all loaded modules, to work if some of the modules
1543 are not accessible. Add symbol_stub() and add_symbol_stub()
1544 as callbacks from catch_errors(). Allow connect attempt to be
1545 interrupted painlessly with ^C (FIXME, there are still some bugs
1546 if the interrupt happens during symbol reading.). Print
1547 final message with puts_filtered, since symbol messages are
1552 * main.c (catch_errors): Only print errstring if non-null.
1553 (command_loop): Avoid an ioctl per command to test ISATTY.
1555 * remote-vx.c (net_load): make static; avoid sophomoric msg.
1556 (vx_xfer_memory): Return correct result!
1557 (vx_files_info): Indicate whether target has float or not.
1558 (vx_lookup_symbol): Complain, not error, if target gone.
1559 (vx_open): Print "Connected" msg before disabling immediate-quit.
1560 [FIXME: lookup_symbol and vx_open changes need testing.]
1562 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
1563 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
1564 contributor lines and update copyrights to 1991.
1566 Changes from an attempted H-PUX host port:
1568 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
1569 defines PT_ATTACH and PT_DETACH but not PT_KILL.
1570 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
1571 * remote-vx.c: include <sys/time.h> for HPUX.
1572 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
1573 "core_file_command" routine to BFD regime. May not work yet.
1575 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
1577 * xgdb.c: Replace X10 version with some VJ version.
1578 (FIXME: Its copyright assignment is not on record.)
1579 * xgdb.c: Update include files to X11R4 (Xaw crud).
1580 (xgdb_display_source, create_text_widget): fix call to
1581 get_filename_and_charpos. Rewack source window stuff for X11R4
1582 (gleaned from include files, and "nm's" of binary libraries, since
1583 I had no doc available).
1584 (append_selection, append_selection_word): Disable with FIXME
1585 since R4 changed interface here.
1586 (create_buttons): Add back the old set of buttons.
1587 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
1589 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
1590 Roll VERSION to 3.94 (not yet final though).
1592 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1594 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
1595 obstack_int_grow, obstack_int_grow_fast): Eliminate
1596 cast on left of assignment, which gives MIPS cc fits and is
1599 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
1600 F_ALIAS. Use printf, not fprintf, when not passing a file
1602 (compare_opcodes): Check that identical instructions have
1603 identical opcodes, complain otherwise.
1605 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
1606 was reported by Roland McGrath.
1607 (unimp): Only match if exactly zero instruction. (Roland)
1608 (branches and traps): Generate all variations of these
1609 instructions with macros, based on a single call that defines
1610 each condition name and its binary representation.
1611 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
1613 * valprint.c (val_print_fields): Take, and use, format parameter.
1614 This means that "p/x struct" again prints the elements in the
1615 desired format. Changed callers.
1617 * stack.c (frame_info): Use filtered output, and indicate wrap
1618 points. Remove kludgy formatting designed to avoid line wrap.
1620 * utils.c (wrap_here): If the line is already full (because
1621 we had printed a long indent or long wrapped string), do an
1622 immediate newline-and-indent.
1624 * m68k-pinsn.c (print_insn_arg): Bugfix from
1626 instruction is incorrectly disassembled as bkpt #8.
1628 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
1630 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
1631 and then will dump core (sometimes). I traced it back to an
1632 uninitialized symfile_name in psymtab_to_symtab.
1633 (const_vol_complaint): Add quotes to message.
1634 (define_symbol): Only believe line number if gcc_compiled.
1635 Avoid allocating symbol if we will not return it.
1637 Add target strata support so that newly established targets go
1638 into their right place in the target stack (e.g. a new exec file
1639 doesn't wipe out the ability to access the running process).
1641 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
1642 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
1643 and initialize it properly in all the targets.
1645 * target.h: Document strata. Change return type of push_target.
1647 * target.c (nomemory): new function for dummy memory access.
1648 (tcomplain): Rename complain, now also used in symfile.c.
1649 (push_target): Push targets within strata. New return value shows
1650 whether new target is on top of stack or not. Always keep dummy
1652 (target_files_info): Ignore dummy target.
1654 * core.c (core_open): Warn user, and skip accessing file, if the
1655 core target is not the topmost target in the stack.
1656 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
1659 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
1660 target_ops, it doesn't belong there since we have no regs there.
1661 Change name of target from machine => memory to clarify.
1663 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
1665 * Freeze version 3.93 for release.
1667 * Makefile.dist: Handle vx-share and nindy-share subdirs
1668 properly when building gdb.tar.Z.
1670 * symtab.c: lint; add no_symtab_msg to consolidate the messages
1671 printed in various places, so I could change just one copy.
1673 * dbxread.c, coffread.c: Change references to bfd->iostream
1674 to cast to FILE *, now that BFD avoids needing types defined
1675 in other header files.
1677 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1679 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
1680 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
1681 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
1682 (actually gcc -Wall).
1684 * dbxread.c: Remove first_global_sym, last_global_sym, since
1685 they are never referenced.
1687 * defs.h (baud_rate): Declare.
1688 main.c: Define it, and add the -b option to set it.
1690 * gdb-int.texinfo: Add text on how to define a new host or target
1691 architecture, prompted by Per Bothner's questions about MIPS
1694 * gdb.texinfo: Document "complaints". Change doc of -q since
1695 gdb no longer prints the copyright and blurb if you specify a file
1696 name to be debugged (just like Emacs). Add doc for Nindy-specific
1697 command line flags for specifying target serial port and such.
1698 Update copyright to 1991.
1700 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
1701 has taken over for us the job of ripping up executable files. The
1702 crud caused Per Bothner's port to not compile.
1704 * infrun.c (normal_stop): Avoid printing "Program exited
1705 normally" if we are in batch mode. This allows a GDB which
1706 executes a program on a target system, to behave like a Unix
1707 command (input from stdin, output to stdout, no extraneous
1710 * main.c (main): Allow additional machine-dependent command line
1711 options to be specified with the ADDITIONAL_OPTIONS,
1712 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
1713 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
1714 processing to occur just before the main loop with
1715 BEFORE_MAIN_LOOP_HOOK.
1716 (main): If a "core file" argument is specified, and it is not a
1717 core file, try it as a process ID to attach.
1718 (symbol_completion_function): Attempt to cope with
1719 "show screen-" TAB, not very successfully. This needs more work,
1721 (batch_file): New function, returns whether we are reading
1722 commands from an interactive tty on stdin, or from somewhere else.
1723 Called by normal_stop since it doesn't get from_tty passed down
1724 to it like many commands do.
1726 * remote-nindy.c: Handle command line options for nindy
1728 (nindy_before_main_loop): Prompt user for tty name if they
1729 don't specify it before getting to the interactive command loop.
1731 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
1732 and -r command line options. Also add hook before main loop
1733 to make it easy to specify a tty.
1735 * TODO: More things to do, one done.
1737 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
1739 * dbxread.c: Make complaint() calls pass pointer, not struct.
1740 Add complaints about badly formatted C++ type information
1741 (const/volatile indicator, and parse errors resulting in
1742 error_type). Fix C++ virtual member fn comment.
1743 (read_struct_type): Avoid bumping pointer if we got a parse
1744 error; this prevents our walking beyond the end of a string.
1745 Terminate loop on null char as well as semicolon.
1746 (process_one_symbol): Fix the LBRAC fix so that it uses the
1747 last previous SLINE, FUN, or SO record's PC address. C++ debug
1748 symbols did not have SLINE records in a useful order compared
1749 to the LBRAC records.
1750 (define_symbol): Handle "catch" records.
1752 * symtab.c (check_stub_type): Added new complain
1753 `stub_noname_complain' and added a consistency check to
1754 keep the debugger from crashing when finishing from an
1755 exception frame. A real fix will be needed later.
1757 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1759 * infcmd.c (attach_command): Make global.
1761 * Makefile.dist (REMOTE_OBS): Make these compile by default,
1762 but make them easy to comment out. Perhaps later they should
1763 be enabled by what CPU you configure for? FIXME.
1764 (VERSION): Roll to 3.93.
1765 (pinsn.o): Remove rule for obsolete file.
1766 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
1768 Run down a problem that manifested by printing the wrong function
1769 name in stack traces of read_ofile_symtab. Turned out that the
1770 problem was the SunOS 4.1.1 (and previous) C compiler outputs
1771 the LBRAC symbol with an address in the *data* segment, which
1772 blew our binary search through the blocks.
1774 * dbxread.c: Use the complain() facility consistently to bitch
1775 about problems in the symbol file we are reading.
1776 (finish_block): Add code to check the nesting of the blocks;
1777 complain and Procrust them to fit if wrong.
1778 (make_blockvector): Check the order of the blocks, complain
1779 [but don't cope] if wrong.
1780 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
1781 symbols to be sure their PC value is greater than the last SLINE
1782 (line number) symbol we've seen, complaining and adopting the
1783 SLINE PC value if wrong.
1785 * symfile.h (struct complaint, complaint_root, complain,
1786 clear_complaints): Add.
1787 * symfile.c (complain, complaint_root, clear_complaints): Add
1788 facility to deal with non-fatal complaints and to regularize their
1790 (symbol_file_add): Clear complaint counters to allow new complaints.
1791 (initialize_symfile): Add 'set complaints' and 'show complaints'.
1793 * dbxread.c (dbx_symfile_read): Remember the address and size
1794 of the string table for the main symbol file, so we won't read it
1796 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
1797 to avoid reading the string table yet again. Lint.
1798 (throughout): Improve filtered output, including word wrap.
1799 (read_range_type): Improve Bothner's fix to handle other types too.
1801 * utils.c: Improve line wrap implementation. Handle unlimited
1802 width by making chars_per_line unsigned.
1803 (puts_filtered): New, easy, function.
1805 * defs.h (puts_filtered): add.
1807 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
1808 call the identical sort_symtab_syms() in symfile.c instead.
1810 * expread.y: Suggest the `file' command rather than `symbol-file'.
1812 * command.h (enum var_types): Add zinteger for seroable
1814 * command.c (do_setshow_command): Handle var_zinteger. Restructure
1815 nested if's into a switch.
1817 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
1818 we did not stop because of a breakpoint (it must have been for
1819 some other reason, like a "stepi"), so don't print anything.
1821 * symtab.c: Include <sys/types.h> all the time. Now that BFD
1822 doesn't include <sys/types.h>, old SunOS's require it for
1827 A test port of gdb-3.92.6 to the Sony NEWS.
1830 Don't normally link in remote- or vx stuff.
1831 Some of it doesn't compile, and it wastes space for 99% of the users.
1832 Remove reference to no-longer-used HAVE_VPRINTF.
1833 Fixed BFD_DEP typo to BFD_DIR.
1835 Fix cast in arg to bfd_h_getlong.
1836 Make char *prefix be const.
1837 Fix how certain range types are mapped into builtin unsigned int types.
1839 Remove 2 #includes. They cause errors (on Sony, at least),
1840 and aren't needed (they wern't in earlier versions).
1842 print_address_symbolic should never demangle labels
1843 (since it prints *assembler-level* labels).
1845 [This was superseded by the change to printcmd below.]
1848 Add some "volatile" return types to avoid warnings.
1849 If MISSING_VPRINTF add vprintf function and not just macro
1850 (since vprintf is used in printcmd.c).
1852 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
1853 (The latter isn't grokked by some PCC-based compilers.)
1855 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
1857 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
1858 * nindy-share/coffstrip.c
1859 Added some forward declarations (otherwise, gcc complains
1860 about implicit extern redefined as static).
1862 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1864 Changes inspired by Per Bothner:
1865 * printcmd.c (print_address_symbolic): Take additional parameter
1866 specifying whether to demangle.
1867 (print_address): Pass in asm_demangle to control demangling.
1868 (print_address_demangle): New fn, takes explicit arg to control
1870 * utils.c: Add new vars demangle and asm_demangle, and let them
1872 (fputs_demangled): If !demangle, just print the argument.
1873 (fprint_symbol): If !demangle, just print raw symbol.
1874 * valprint.c (val_print): Call print_address_demangle rather than
1875 print_address, to cause demangling to depend on the global
1876 rather than assembler-level demangling setting.
1877 * WHATS.NEW, gdb.texinfo: Document.
1879 * main.c (show_command): Show all settings if no arg.
1880 (initialize_main): Make "info set" the same as naked "show".
1881 * command.c (cmd_show_list): Handle prefix commands in the
1882 list, and print the name of the setting as well as its English
1883 description and value.
1885 Allow gdb functions to specify where a line should wrap if it
1886 exceeds the size of a terminal line. Use it to make the output
1888 * utils.c (set_screen_width_command): New fn, mallocs a buffer
1889 of the right size when screen width changes.
1890 (set_screensize_command, screensize_info): Remove #if 0'd fns.
1891 (wrap_here): New fn, indicates a point in the output where we
1892 should wrap the line rather than just letting it overflow at a
1894 (fputs_filtered): Implement wrapping.
1895 (n_spaces): New fn, returns a pointer to N spaces.
1896 (print_spaces_filtered): Use n_spaces.
1897 * defs.h (n_spaces): Declare.
1898 * stack.c (print_frame_info): Wrap with 4-space indent after
1899 fn name and before filename and line number.
1900 * printcmd.c (print_frame_args): Wrap with 4-space indent
1901 before each argument name is printed.
1902 * valprint.c (value_print): Wrap with no indentation before
1904 (val_print_fields): Wrap with indentation relative to nesting
1905 level before each field name.
1906 (val_print): Wrap with nesting indentation before array elements.
1907 * command.c (do_setshow_command): Avoid extra newlines,
1908 wrap with 4-space indent around values printed, end with period.
1909 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
1911 * breakpoint.c (breakpoint_1): Implement addressprint for
1912 "info breakpoints" display. Change file name and line number
1913 format to " at file:nnn" rather than " (file line nnn)".
1914 * gdb.texinfo: Document.
1917 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1919 Frozen for gdb-3.92.6 release.
1921 README, WHATS.NEW: Update for 3.92.6 release.
1923 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
1924 coffread.o from configs since it is now built by default.
1925 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
1926 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
1927 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
1928 from configs since it is now built by default.
1930 Makefile.dist: Update for release 3.92.6. Handle files that
1931 have been moved to ../include, ../getopt, or ../bfd. Add
1932 saber.suppress and tests directory. Add config.status to
1933 the release (it will say "none").
1935 coredep.c: Minor formatting fixes.
1937 These changes were made in early December but only checked in now:
1938 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
1939 nindy-share/nindy.c: lint
1940 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
1941 register values coming back from the target; we store values
1942 in target byte order everywhere.
1944 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
1946 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
1948 * valprint.c (cplus_val_print, val_print_fields): New functions,
1949 which print C++ objects. They conspire to avoid printing a
1950 virtual base class more than once, following all the twists and
1951 turns of C++ virtual base rules.
1952 (val_print): Call the above rather than do it by hand.
1954 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
1955 symbol file, not for added files like shared libs. This really
1956 needs to be generalized to a timestamp per file.
1958 * core.c (cleanup_core): Avoid coredump if no core file.
1960 * config.gdb: Accept -host or -target in place of +host or
1963 * coffread.c (find_linenos): Avoid desupported BFD interface
1964 to line numbers. We still read them manually rather than using
1965 BFD's "generic" features.
1967 * gdbrc.tex, threecol.tex: Add GDB reference card and its
1969 Makefile.dist: Add refcard to OTHERS list for creating tar files.
1971 * Makefile.dist: Eliminate use of $< in explicit targets.
1973 * readline/Makefile: Use $< rather than $*.c, which does not
1974 include the VPATH in GNU Make.
1976 * tconfig/i960-bout, tconfig/i960-coff: These are identical
1977 copies of tconfig/i960, added for global configuration
1978 compatability. All i960 versions can read both coff and b.out.
1980 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
1981 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
1984 * TODO: Think of more things to do.
1986 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
1988 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
1989 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
1990 64-bit float conversion.
1992 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
1993 equivalent to sun?os4 so global config works.
1995 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
1999 * main.c: Only declare linesize once; declare pagesize not at
2000 all, since it is never used.
2001 (main): Clear newly allocated line before it is used.
2003 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2005 Further stabilization for the Intel 960.
2007 * Makefile.dist: Parameterize the location of the "include"
2008 and "bfd" directories, as well as "getopt". Add symfile.c.
2009 Link in both dbxread and coffread. Fix up "make depend" to
2010 rewack the locations of include, bfd, and getopt in its output.
2012 * README: Document moving include files, improve some of
2015 * coffread.c: Move common code out to symfile.c. Change
2016 symbol_file_command style interface to use new *_symfile_init
2017 and *_symfile_read interface under BFD. Use BFD internal
2018 info to locate line table, symbols, etc.
2020 * core.c (core_fetch_registers): Rename to get_core_registers
2021 to avoid confusion with fetch_core_registers.
2022 (register_addr): Move to coredep.c, which is already machine
2023 dependent. This leaves core.c pretty clean of dependencies.
2025 * coredep.c (register_addr): Accept this routine from core.c.
2027 * dbxread.c: Move common code (with coffread.c, etc) into new
2028 symfile.c. Each psymtab now contains a pointer to the
2029 format-dependent function that knows how to read it in. Make
2031 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2032 (process_one_symbol): Add code to complain about a "compiler bug
2033 we muzzle here", if we actually see it.
2035 * eval.c (evaluate_subexp): Insert missing "break" statements
2036 in code that determines whether a variable is an lvalue in
2037 memory, register, or whatever. I detected this via a compiler
2038 bug in which it *almost* mashed out the whole switch statement.
2040 * gdb-int.texinfo: Add minor sections on configuring gdb for
2041 release, and about the README file.
2043 * infcmd.c (registers_info): Fix formatting somewhat. Still
2044 not as pretty as before, but it handles byte swapping.
2046 * remote-nindy.c: If data cache routines are interrupted while
2047 waiting for the remote end, be sure that any uninitialized cache
2048 blocks are on the free list, not on the valid list!
2050 * symfile.h: Flesh out this header file with all the various
2051 routines and variables that have been merged in from dbxread.c
2052 coffread.c, and symtab.c to symfile.c.
2054 * symfile.c: New file, containing code common to dbxread.c,
2055 coffread.c, and some code from symtab.c. All generic code for
2056 reading symbol files should be in here now.
2057 (unrecord_misc_function): Remove unused function.
2059 * symtab.h: Remove file-reading things to symfile.h.
2061 * symtab.c: Remove file-reading things to symfile.c.
2063 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2064 to decode i960 fault types.
2066 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2067 target.c: Change type of the "resume" function from int to void,
2068 since its result was never used.
2070 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2072 * main.c: Replace "stupid" with "caution"; you now "set caution
2075 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2077 * infcmd.c (do_registers_info): Call val_print to deal with the
2078 byte order of the registers being printed. FIXME, this makes
2079 the formatting of the output uglier.
2081 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2082 defined, call it for signals the debugger doesn't itself use.
2083 The i960 uses this for more detailed fault information.
2085 * remote.c (remote_open): If arg is null, print help rather than
2088 * sparc-xdep.c (register_valid): Avoid declaring size, since
2089 various modules will think of various sizes depending on the
2090 architecture of their tm-file. FIXME, we need protection against
2091 actually entering one of those modules, which would clobber
2092 storage if not for the target architecture compiled into gdb.
2094 * stack.c (up_command, down_command): Always print the frame
2096 (up_silently_command, down_silently_command): New commands
2099 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2101 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2102 more parameters than it used to.
2104 * findvar.c (registers): Increase slop to 256 bytes, which should
2105 protect us against even most RISC machines with large register
2107 (locate_var_value): Move declaration inside related ifdef.
2109 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2110 throughout, to avoid throwing away buffered input from the board.
2111 (nindy_wait): Supply_register takes addr_of_value, not value.
2112 (i960_print_fault): Renamed from i80960_fault.
2113 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2114 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2116 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2117 we can set the PC in the call to proceed(). Unpush nindy_ops
2118 before pushing it on top, to avoid message to user. Eliminate
2119 commentary from Unix machines that just misleads here.
2120 (reset_command): Fix error message to suggest target command.
2122 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2124 Release 3.92.5 as frozen.
2126 Stabilize the merged release...with help from lint, Saber C,
2129 Everywhere: Add include files needed to declare return types
2130 of functions called.
2132 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2134 * breakpoint.h: Add undeclared breakpoint functions, and some
2135 functions for display handling since I couldn't think of a better
2138 * breakpoint.c (insert_breakpoints): Make code for disabling
2139 shared library bkpts more likely to work. It's used when we
2140 rerun a program and stop before the shared library has been
2142 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2143 cast from pointer, so it squeezes through catch_errors.
2144 (bpstat_stop_status): Fix logic broken some time ago. We now
2145 always create a bpstat if the stop address matches a breakpoint,
2146 even if we don't stop there -- just like the old code used to do
2147 before I got my fingers into it (sigh).
2148 (breakpoint_1): Print "ignore count" after "stop only if"
2149 condition, since that's how it actually works.
2150 (mention): Handle watchpoints as well as breakpoints.
2151 (watch_command): use set_raw_breakpoint and mention to do most
2152 of the work (and initialize all the fields!). Only pass one
2153 arg to parse_c_expression, since that's all it takes.
2155 * command.c (not_just_help_class_command): Rename arg to args
2156 since we ignore "unused argument" warnings on vars named "args".
2157 inflow.c (child_terminal_info): ditto.
2158 infptrace.c (kill_inferior): ditto
2159 main.c (catch_errors, version_info, quit_command, pwd_command,
2160 source_command, dump_me_command, editing_info,
2161 set_history_size_command, set_history, show_history,
2163 stack.c (locals_info): ditto
2164 target.c (target_files_info): ditto
2165 valprint.c (set_input_radix, set_output_radix): ditto
2167 * core.c: Remove old variables for handling core and exec file
2168 sections (data_start, data_end, stack_start, stack_end,
2169 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2170 text_end, exec_data_start, exec_data_end, text_offset,
2171 exec_data_offset, data_offset, stack_offset). They're
2172 superseded the more general build_section_table and
2174 (get_exec_file): Mention the `file' command.
2175 (read_memory_check): Rename to memory_error, and only call it
2176 in the case of an actual error.
2177 (read_memory, write_memory): call memory_error.
2178 (core_fetch_registers): Register section name is ".reg".
2180 coredep.c: Remove a bunch of crud now that all this file does
2181 is pull the registers out of a core file.
2182 (fetch_core_registers): Rewrite to actually work, I hope.
2184 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2185 Replace index() with strchr(). Remove all the pre-BFD macro
2186 definitions for accessing the symbol file.
2187 (struct dbx_symfile_info): Encapsulate the information that
2188 dbx_symfile_init needs to pass to dbx_symfile_read in this
2191 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2192 dbx_symfile_discard): Rearrange symbol file reading to divide
2193 the format-specific part from the format-independent part,
2194 leaving the format-independent part such as file name expansion
2195 and opening in symtab.c. This replaces
2196 partial_symbol_file_open and partial_symbol_file_read.
2197 Symbol_file_read, add_file, add_file_target_command,
2198 add_file_addr_command move to symtab.c. Pass an explicit
2199 "mainline" flag for when reading the main symbol table, rather
2200 than relying on the offset address to be zero or nonzero.
2202 (dbx_symfile_read): Don't allow void *'s to be printed as
2204 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2205 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2206 macro" debug version really work.
2207 (read_dbx_symtab): Remove unref'd parameter inclink.
2208 Avoid swapping N_SLINE symbols, for speed.
2209 Merge N_TEXT!N_EXT case with the other external symbol
2210 definitions' case. Add comments.
2211 (start_psymtab): Allocate the symfile name in the psymtab on
2212 the psymbol_obstack, rather than using the caller's storage.
2213 (end_psymtab): Only allocate a dependencies list if there are
2215 (psymtab_to_symtab_2): Use BFD when reopening file to read
2216 its symbols for real.
2217 (read_struct_type): Add FIXME comments where it needs work
2219 (read_huge_number): Add FIXME about overflows.
2220 (read_range_type): Add FIXME about comparing a long to 1<<32.
2222 * coffread.c: Minor changes to move things closer to the new
2223 regime with symtab.c and dbxread.c Major work is still needed
2226 * exec.c (exec_file_command): Remove old variables (see core.c
2228 (xfer_memory): If memory transfer is right at the end of a
2229 section, don't lose.
2231 * findvar.c (get_saved_register): If value is in a real
2232 register, LVAL is lval_register, not lval_memory.
2234 frame.h: Declare print_sel_frame and record_selected_frame.
2236 gdb-int.texinfo: New file, for GDB internals documentation.
2237 Very simple, unformatted doc of cleanups is there for now.
2239 gdbcore.h: Remove obsolete variables that described a.out
2240 section addresses and offsets. (See core.c above.)
2241 Declare fetch_core_registers and registers_fetched.
2243 getopt.c: Declare char *alloca(); even on SPARC.
2245 infcmd.c (run_command): Call target_kill rather than
2247 (step_command, next_command, stepi_command, nexti_command):
2248 Declare from_tty parameter even though we don't use it.
2249 (run_stack_dummy): argument BUFFER is a char array, not
2250 a pointer to REGISTER_TYPE.
2251 (finish_command): using_struct_return needed a value *,
2252 not a struct symbol *.
2254 * infptrace.c (child_xfer_memory): To avoid dependency on
2255 where sections are in memory, try PT_WRITE_D and if that fails,
2256 try PT_WRITE_I. Most Unixes don't care which you use.
2258 * infrun.c (step_resume_break_shadow): Change to array to
2259 match other breakpoint shadow storage.
2260 (clear_proceed_status): Pass address of bpstat to
2261 bpstat_clear, not the bpstat itself.
2262 (child_create_inferior): FIXME comment about if the child
2264 (start_inferior): Remove old function.
2265 (child_open): Use target_kill rather than kill_inferior.
2266 (wait_for_inferior): Ditto.
2267 (insert_step_breakpoint, remote_step_breakpoint): Use
2268 new step_resume_break_shadow.
2270 * inftarg.c (child_wait): If all child processes die,
2271 pretend that the one being waited for exited with signal 42.
2273 * main.c (command_line_input): When scanning for comments,
2274 don't coredump on unclosed quotes.
2275 (quit_command): Use target_kill rther than kill_inferior.
2276 (_initialize_main): Rename class_user from "user" to
2279 * printcmd.c (print_command_1): Initialize "fmt" if no format
2280 is specified by the user.
2281 (print_frame_args): Only add to args_printed if we are
2282 actually fetching args from the stack (avoiding undefined
2284 (_initialize_printcmd): Remove bogus \{ from string.
2286 * remote-eb.c (eb_open): Avoid coredump on no argument.
2288 * remote-nindy.c: Bring out of Intel environment into new
2289 target environment. Remove all conditional compilation on
2290 I80960. Massive hacking throughout.
2291 (nindy_xfer_inferior_memory): New routine stolen from
2293 (nindy_create_inferior): New routine pieced together, probably
2294 not quite working yet.
2295 (nindy_ops): New target_ops struct for nindy.
2297 * remote-vx.c: Use write_memory rather than target_write_memory
2298 to get error checking.
2299 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2301 (vx_create_inferior): Use target_terminal_ours...
2303 * signame.c (_initialize_signame): Always initialize, since
2304 we need the table for things other than psignal.
2306 * solib.c (solib_add): Use symbol_file_add, not add_file.
2307 (solib_address): Return boolean result rather than struct
2308 pointer which nobody else knows the type of.
2310 * sparc-tdep.c, valops.c: Use write_memory rather than
2311 target_write_memory, to get error checking.
2313 * stack.c (locals_info, catch_info, args_info,
2314 get_selected_block, frame_command, up_command): Use
2315 target_has_stack, rather than have_inferior_p or
2318 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2320 * symfile.h: New file, defining the interface between the
2321 generic and object-file-specific symbol reading code.
2323 * symtab.c: Move generic symbol-reading interface to symtab.c,
2324 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2325 table to map BFD targets to symbol-reading modules in GDB.
2326 Change index to strchr.
2327 (lookup_struct_elt_type): Use error() rather than hand-made
2328 simulations thereof.
2329 (lookup_partial_symbol): Speedup slightly when length == 0.
2330 (symbol_file_add): New function.
2331 (symbol_file_command): Call it.
2332 (symfile_open, symfile_init): New function.
2333 (add_file_target_command, add_file_addr_command): moved from
2336 * target.c (target_command): use target_kill.
2338 * target.h (target_files_info): Don't declare, never called
2341 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2342 files to determine stack end address.
2344 * valarith.c (value_x_binop, value_x_unop): Change error message
2345 to be more useful. Pass proper argument to value_struct_elt.
2347 * valops.c (value_assign): FIXME comment that long long
2348 bitfields will break here.
2350 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2351 Update `make saber_gdb' to work better.
2353 * TODO: A woman's work is never done.
2355 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2356 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2357 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2358 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2359 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2360 valops.c, valprint.c, exec.c: Lint.
2363 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2365 Continuing Intel 960 port merge of GDB.
2367 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2368 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2369 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2370 Wack over "make depend" so it handles files in subdirectories
2371 vx-share, nindy-share, bfd, and in the current directory.
2373 * blockframe.c (get_prev_frame_info): Remove fatal error
2374 if stack not defined.
2376 * core.c (core_open, core_detach): New functions that handle
2377 the old "core-file" command as "target core" and "detach" instead.
2378 (core_file_command): Call them.
2379 (core_xfer_memory): Use common routine xfer_memory.
2381 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2382 dbxread now uses bfd for everything but symbol reading itself.
2383 BFD internals are used to drag out the relevant file offsets.
2384 (partial_symbol_file_open): Change args all around for BFD.
2386 * symtab.c: Rename "value" to "val" everywhere, so we can
2388 (symbol_file_command): New command, moved from dbxread.c
2389 and coffread.c. It uses BFD to read the file, then vectors
2390 based on its type, to dbx or coff symbol readers.
2391 * symtab.h: Extern a few vars for symbol_file_command.
2393 * target.h: Breakpoint takes a char * save area, not a char **.
2395 * valprint.c (val_print): When unpacking bitfields, offset
2396 the address in gdb of the value, if it is declared with a shorter
2397 type. Remove the last "runtime kludge test" of host byte order.
2399 * utils.c: Remove old my_bfd_read routine.
2401 * stack.c (frame_info): Use target_has_stack. Print program counter
2402 register's actual name rather than "pc", since it's called the
2403 "ip" (instruction pointer) on the i960 (sigh).
2405 * target.c (target_command): Add command for selecting a target
2406 type and calling its open routine. This is used for initiating
2407 communication with a particular target, in a generic way.
2409 * tm-i960.h: Update for modern gdb. Remove semicolons from
2410 various macros. Handle reading struct return convention, and
2411 error-out attempts to return structs with the "return" command.
2412 Be sure gdb doesn't think we know how to call functions in the
2415 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2416 to i960_xxx in lower case.
2417 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2418 not being defined yet.
2420 * remote.c (remote_open): Call start_remote to initialize
2421 wait_for_inferior during open.
2422 (remote_xfer_inferior_memory): Return length written rather
2425 * remote-vx.c (target_command -> vx_open): Use new generic
2427 * remote-eb.c, inftarg.c, exec.c: ditto.
2429 * infrun.c: Fix comments.
2430 (attach_program -> child_open): Use new generic target command.
2431 (wait_for_inferior): Clear saved register values before target_wait,
2432 so target_wait can set some of them if convenient.
2434 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2435 Return success indicator, not void.
2436 (child_xfer_memory): Avoid fetching initial word if we'll
2437 overwrite it anyway.
2439 * infcmd.c (attach_command): Use new generic target open routine.
2440 (_initialize_infcmd): Update doc on attach and detach commands.
2441 (do_registers_info): Merge in a byte-order problem as a FIXME
2444 * findvar.c (find_saved_register): Avoid problem in current frame.
2445 (read_relative_register): Ditto.
2446 (write_register): Convert byte order on the way out.
2448 * exec.c (file_command): Add.
2449 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
2450 (xfer_memory): Common function between core_xfer_memory and
2452 (exec_xfer_memory): Use it.
2454 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
2456 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
2457 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
2458 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
2460 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
2462 Merge Intel 960 port of gdb, continuing...
2464 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
2465 symbol_file_command): Pass from_tty arg to hush 'em up.
2467 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
2468 Add magic numbers for 960 COFF format.

2485 Tue May 29 12:54:49 PDT 1990
2486 Added variable baud rate (-b switch).
2487 Source code reorganization.
2489 Thu Apr 26 11:09:55 PDT 1990

2493 Fri Apr 20 13:47:15 PDT 1990
2496 Thu Apr 19 09:54:28 PDT 1990
2497 Add 'reset' command.
2499 Wed Apr 18 09:48:07 PDT 1990
2500 After opening remote tty, wait for 1 second to go by without input
2501 from it before trying to talk to NINDY (fixes problems with the
2502 Heurikon HK80/V960E).
2504 Mon Apr 4 16:33:05 PDT 1990
2505 Some output was not being suppressed in 'batch' mode.
2507 Thu Mar 22 15:31:11 PST 1990
2508 Ask user if old symbol table should be deleted when new file is

2538 Mon Oct 2 15:56:31 PDT 1989
2540 Added 960CA disassembly support.
2542 To simplify maintenance:
2543 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
2545 - eliminated opcode.h: incorporates tables into i960-pinsn.c
2546 - moved 960-specific routines from i960-pinsn.c to i960-md.c
2547 - made disassembly interface identical to that in gdmp960.
2551 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
2553 * target.h: Allow targets to stack. Add target_has_memory,
2554 _registers, etc. Restructure memory access and "info files"
2555 to walk the target stack.
2556 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
2557 target.c: Change tables to match target.h.
2558 * inflow.c (child_mourn_inferior): pop child_ops.
2559 (generic_mourn_inferior): Use new has_stack flag.
2560 * infptrace.c (child_xfer_memory): New memory regime.
2561 * inftarg.c (child_files_info): New "info files" regime.
2562 * remote-eb.c: New memory regime, new info files.
2563 * remote-vx.c: New memory regime, new info files. Now use
2564 separate targets for VxWorks attachment to machine, and
2565 actually running a process under VxWorks, since one has
2566 stack & execution & regs and the other doesn't.
2567 * remote.c: New memory regime, new info files.
2568 * sparc-xdep.c (fetch_core-registers): New memory regime.
2569 * target.c: New routines and support for stacked targets,
2570 new memory regime, new info files regime.
2573 Generalize section handling for an arbitrary number of sections,
2574 including use of the new BFD (binary file) library.
2575 * gdbcore.h: Add struct section_table.
2576 * exec.c (build_section_table): Iterate all sections and
2577 record what gdb needs to know about them.
2578 (exec_command): Use it.
2579 (exec_xfer_memory): Use the table.
2580 (exec_files_info): Print the table.
2581 * core.c (core_file_command, core_xfer_memory, core_files_info):
2583 * source.c (find_source_lines): Use bfd_get_mtime.
2584 * dbxread.c: Quick changes to make it compile with new BFD.
2585 * utils.c (error): Avoid using bfd_error in generic routines.
2587 * core.c (core_fetch_registers): Get from the ".regs" section of
2589 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
2591 * inferior.h (attach_flag): Export.
2592 * infcmd.c (run_command): use new target_create_inferior.
2593 * infrun.c (child_create_inferior): Don't return result.
2594 * Makefile.dist (VERSION): 3.91.4.
2596 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
2598 * breakpoint.c (bpstat_num): Handle breakpoints which have
2599 since been deleted, such as temporary breakpoints.
2600 infcmd.c (program_info): ditto.
2602 * core.c (core_file_command): Display the frame where the core
2607 * remote-vx.c (target_command): Merge in target command from
2608 targ-vx.c. A few other cleanups.
2610 * TODO, Projects: Lots more stuff to do...
2612 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
2614 Massive changes to wall off the remote-debugging interface
2615 behind a function vector. The port to handle VxWorks targets
2616 is also part of this.
2618 All files: Replace references to renamed functions,
2619 remove references to remote_debugging, remove references to
2620 have_include_file, have_core_file in favor of target_has_stack,
2621 target_has_memory, etc.
2623 * Modularize the breakpoint interface.
2624 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
2625 a breakpoint instruction.
2626 breakpoint.c: struct breakpoint's shadow_contents now sized as
2628 (insert_breakpoints): Vector to target to install breakpoints.
2629 (remove_breakpoints): Vector to target here too.
2630 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
2631 sparc-tdep.c (single_step): Use new breakpoint interface for
2632 the single-step breakpoints.
2633 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
2634 New file, contains routines to insert and remove breakpoints by
2635 reading out the old contents and later replacing them. This is
2636 how ptrace breakpoints work, and many remote systems as well.
2638 * tm-vxworks68.h: New config file, overrides a few things for
2639 Wind River's preferences.
2641 * target.h: New file, for transfer vector used to talk to the
2642 inferior (child, attached, core, exec, remote, etc). All accesses
2643 to the thing being debugged should come through these vectors.
2644 target.c: New file, routines to handle transfer vector.
2645 (various files): Add transfer vectors XXX_ops for the various
2646 targets and pseudo-targets (core files, etc) we support.
2648 * breakpoint.c (bpstat_stop_status): Further explorations of
2649 watchpoints and why things don't work all the time.
2650 (bpstat_alloc): New fn to allocate a bpstat and chain it.
2652 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
2653 the local gdbinit if it doesn't already have it.
2655 * core.c (core_ops): add and install.
2656 Allow core debugging without exec file.
2658 * dbxread.c (free_and_init_header_files): Merge two fns.
2659 (end_symtab): Free named symbol table when a new version comes in.
2660 (read_dbx_symtab): Relocate all kinds of symbols with base
2661 address. First step toward handling different text, data, bss
2663 (add_file_addr_command): Renamed add_file_command.
2664 (add_file_command): Vector to remote handler.
2665 Add "load" as an alias for "add-file" command.
2667 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
2668 non-returning functions.
2670 * exec.c: Add exec_ops, and push it as a target when an exec
2673 * infcmd.c (run_command): Pass executable file name and arg list
2674 separately when starting an inferior. Permit "run" when no exec
2675 file is specified, for VxWorks.
2676 (detach_command): Move to child_detach in inftarg.c.
2678 * inftarg.c: New file. Unix-child-specific routines, and the
2679 child_ops structure.
2681 * inferior.h (registers): Export "registers" as the way for
2682 target dependent register handlers to find gdb's local copy of
2683 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
2684 since it is now used by places that want wait_for_inferior to
2685 handle the grunge but want to see every trap from the inferior.
2687 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
2688 Eliminate remote_debugging hooks in terminal handling.
2690 * infrun.c: Replace start_inferior with child_create_inferior.
2691 Move all the hair of Unix shells and ptrace idiosyncracies into
2692 child_create_inferior, so remote handlers don't have to deal.
2693 Remove running_in_shell. Rename stop_after_attach to
2694 stop_soon_quietly, and use it in a few other places where we want
2695 to just call wait_for_inferior and get control back on the first
2696 trap. trap_expected now never takes a value > 1.
2697 (init_wait_for_inferior): Initialize static vars when a new
2700 main.c (gdbinit): Add new hook for .gdbinit file name, let
2701 it be overridden by config files as GDBINIT_FILENAME.
2702 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
2703 Both of these are used for VxWorks gdb.
2705 mcheck.c: rename include file "gmalloc.c" to avoid problems
2706 with system include file "malloc.c".
2708 param-no-tm.h: New include file, same as param.h but does not
2709 include the default "tm.h" file. This is used in files where
2710 the target is known, e.g. remote-eb.c or sparc-xdep.c.
2712 param.h: Now just a shell that includes tm.h and param-no-tm.h.
2714 remote-vx.c: New file, VxWorks remote debugging support. Uses
2715 RPC routines that are shared with the target system, in directory
2718 remote.c: Vectorize remote interface.
2720 source.c: Globalize source_path, and make an alias "l" for "list"
2721 since we now have the "load" command.
2723 sparc-xdep.c: Use new param-no-tm.h.
2725 symmisc.c (free_named_symtab): Add new function from Wind River.
2726 However, ifdef it out for now while we think about what it should
2729 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
2731 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
2732 non-Unix-children handle this with their own code in the target
2735 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
2736 source and target lists. Add vx-share to default list of include
2737 directories. Add new files to src and target lists: mem-break,
2738 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
2739 ${srcdir} versions of munch and createtags are used.
2741 * valops.c (find_function_addr): Split out of call_function.
2742 (call_function_by_hand): Rename call_function; this function
2743 calls functions in the target by laboriously patching the target
2744 word-by-word with the right stack, args, regs, etc.
2747 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
2749 Handle AMD 29000 a bit better.
2751 * remote-eb.c (readchar): Mask received char log to make it readable.
2752 (remote_start): Pass arguments down to executing program.
2753 Make startaddr unsigned.
2754 infrun.c (start_inferior): Accept args, pass them to
2756 infcmd.c (run_command): Pass args down to start_inferior.
2758 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
2759 the target object file format.
2760 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
2762 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
2763 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
2765 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
2767 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
2768 * TODO: We did a few things, we have more to do though.
2770 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
2771 * inflow.c (inferior_died): Clear deferred stores.
2773 * Debug problems with dummy frames and calls to the inferior.
2774 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
2775 * sparc-tdep.c (do_restore_insn): Simplify.
2776 (sparc_frame_find_saved_regs): Simplify and fix what we find.
2777 (sparc_push_dummy_frame): Simplify and fix what we push.
2778 (sparc_pop_frame): Slightly more hair here, deciding whether
2779 we are restoring a saved PC or returning to a return address in %i7.
2780 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
2782 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
2783 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
2784 * obstack.h (chunkfun): ditto.
2785 * defs.h (xmalloc, xrealloc): ditto
2787 * utils.c (quit): Grab the terminal from the child if necessary.
2789 * inflow.c (term_status_command): Rename to term_info, change
2792 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
2793 (is_delayed_branch): Speed up.
2794 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
2795 Still missing some float ops, and needs testing.
2797 * Support for input and output radixes other than base 10
2798 * defs.h (input_radix, output_radix): Declare.
2799 * expread.y (yyparse, parse_number): Handle changes of input
2800 radix, and ambiguous names-or-numbers in radixes >10.
2801 * printcmd.c (print_scalar_formatted): Print formatted hex
2802 numbers in varying column widths.
2803 * valprint.c (val_print): Use output_format to print scalar ints.
2804 (set_input_radix, set_output_radix, set_radix): Create.
2805 (set_output_radix): Set output_format from output_radix.
2806 (_initialize_valprint): add `set radix' but leave the others off.
2808 * main.c (execute_command): Let stupid questions be turned off.
2809 (_initialize_main): Handle "set stupidity", etc.
2811 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
2812 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
2814 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
2816 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
2817 bfd stuff is still screwed up, but with some manual work, it
2820 * breakpoint.c (bpstat_do_actions): Start over if a command
2821 proceeds the inferior, since the inferior will have stopped and
2822 will need to have its new stop-actions taken care of.
2824 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
2825 compiler fits, simplify it.
2827 * gdb.texinfo (directory command): Doc new dir command.
2828 source.c (directory_command): "dir" now puts things on the front
2829 of the path, moves dups up front, and handles multiple names
2830 on the command line, inserting each one in order. It also
2831 blows away cached line and full_filename info.
2833 * stack.c (backtrace_command): Skip "more stack frames follow"
2836 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
2837 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
2838 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
2839 The only odd one was Gould NP1, which had defined vprintf to
2843 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
2844 variable, inspect_it.
2845 valprint.c (print_string, val_print): Use the global inspect_it
2846 to indicate whether to print in Epoch style or normal style.
2848 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
2850 * printcmd.c (call_command): add an alias for the "print" command
2851 which runs expressions and doesn't print the result if void.
2852 (print_command_1): implement it.
2854 * command.c: Remove #if 0'd code. Initialize all the fields
2855 in add_cmd (). Rename do_nothing_command to
2856 not_just_help_class_command, and make it externally visible.
2857 command.h: add user_commands to struct.
2858 * main.c (define_command): Don't overload c->function with a char
2859 string as well as a function pointer.
2861 * eval.c (evaluate_subexp): Reinstall tiemann changes to
2862 calling convention of value_struct_elt () that got dropped in
2865 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
2866 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
2868 * tm-sparc.h (POP_FRAME): replace some constants with defines.
2870 * sparc-xdep.c (store_inferior_registers): defer stores to regs
2871 until a good time (e.g. when we are about to run the child),
2872 saving ptrace calls.
2873 * infrun.c (proceed): handle DO_DEFERRED_STORES.
2874 * tm-sparc.h: define DO_DEFERRED_STORES.
2876 * sparc-xdep.c (store_inferior_registers): when storing float
2877 registers, don't store stack regs too. When storing the SP,
2878 however, DO store the stack regs too. This fixes a bug in which
2879 the dummy frame is not recognized when a call_function finishes,
2880 because its frame pointer (in the stack regs) was never
2882 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
2883 even though we don't know how to read them from an inferior.
2884 valops.c (call_function): Comment about storing SP.
2886 * infrun.c (save_inferior_status): Save away the original bpstat
2887 chain so it can be restored later. Install the copied version for
2888 use by whoever saved the status. It will be blow away by
2889 restore_inferior_status, and the original chain restored. This is
2890 important for people who have pointers into the original.
2892 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
2893 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
2894 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
2897 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
2899 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
2900 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
2901 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
2903 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
2905 * Merge Mike Tiemann's multiple inheritance changes from Sun.
2906 Store the baseclasses in a type struct starting from array element
2907 0 rather than from the unusual array element 1.
2909 dbxread.c: the above.
2910 (virtual_context): Add
2911 Read new debug information about which virtual function table
2912 a virtual function is from, and store it in fn_field.fcontext.
2914 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
2915 TYPE_FN_FIELD_STATIC_P.
2917 symtab.c: the above.
2918 valops.c: the above. Handle pointer casts of object *'s.
2919 (search_struct_method): Add.
2920 (value_struct_elt): First arg is now a pointer to a value, and is
2923 valprint.c: the above.
2924 values.c (value_virtual_fn_field): Add type arg. Handle
2925 offsetting to the proper object when calling virtual fns.
2927 (baseclass_addr): Add valuep arg.
2929 * README: Document the current state of BFD config (missing).
2930 * TODO, ChangeLog, Makefile.dist: Roll version.
2931 * WHATS.NEW: Add summary of changes since 3.5.
2933 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
2935 * dbxread.c (read_struct_type): Clear bit vectors whenever
2937 symtab.c (B_CLRALL): define.
2939 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
2940 using == rather than =. Huh... This fixes the dreaded problem
2941 wherein builtin_type_int becomes TYPE_CODE_FLT.
2943 * core.c (info_files): Show the inferior pid.
2945 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
2946 already knows how to look in the source directory.
2948 * Remove psymtab hair from many places. Remove duplicated code
2949 for searching symbol tables. Hide psymtabs from most places.
2950 Make it fast to get from a psymtab to its symtab.
2952 blockframe.c (blockvector_for_pc): Remove psymtab hair.
2953 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2954 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2955 dbxread.c: export psymtab_to_symtab, make it work if called N times.
2956 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
2957 new symtab completely. New psymtabs get symtab pointer
2958 initialized to zero. Remove MI warning printf.
2959 symtab.h: Comments. Add psymtab to symtab pointer.
2960 (PSYMTAB_TO_SYMTAB): New macro.
2961 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
2962 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
2964 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
2966 (print_frame_info): Avoid special-casing symbols that have not yet
2969 * source.c (open_source_file): Quick path if we have already
2970 located the source file by its full name.
2972 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
2973 find_pc_psymtab. When a name is found in the misc function
2974 vector, search the symbol table for its mangled name, not the
2975 name that the user typed.
2977 * bfd.h: Fix missing comment terminators, make #endifs match.
2979 * valarith.c (value_less): Handle unsigned int comparisons.
2980 Add FIXME about pointer compares, which assume host and target
2981 pointers are the same.
2983 * command.c (do_nothing_command): lint
2984 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
2985 fix comments on debug symbol format for visibility. Actually set
2986 visibility of symbols.
2987 main.c (echo_command): lint; use <readline/history.h>.
2988 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
2989 obstack.h (_obstack_blank): Rearrange pointer math to avoid
2990 pointing past end of allocated memory; saber complains.
2991 obstack.h: Declare the external functions that we use.
2992 valarith.h: use <string.h>
2993 solib.c (solib_add): lint.
2995 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
2997 * main.c (initialize_main): Default info_verbose to off, now that
2998 symbol reading is fast.
2999 (quit_command): Avoid clobbering exec_bfd while quitting.
3001 * Initial BFD (binary file diddling library) merger:
3002 coffread.c: Change AOUTHDR to struct exe_hdr.
3004 core.c: initialize initialized data at compile time.
3005 (core_file_command): Move from coredep.c, convert to bfd.
3006 (xfer_core_file): Convert to bfd.
3007 exec.c (exec_file_command): use bfd routines.
3009 mips-tdep.c: Remove exec_file_command and friends.
3012 * coredep.c: (fetch_core_registers) Convert core_file_command to
3013 fetch_core_registers.
3014 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3016 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3017 (my_bfd_read): More bogosity, which I don't think we call.
3018 (program_name): Remove this atrocity asap!
3020 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3023 values.c: allocate_repeat_value was not clearing the
3024 optimized_out field.
3025 (value_static_field): minor stylistic fix (wrong macro was used).
3026 valops.c (value_struct_elt_for_address): didn't work for C++
3029 * signame.c (_initialize_signame): Initialize signal names once.
3031 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3032 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3033 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3035 * remote-eb.c: Support user-settable baud rates on the serial port.
3037 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3039 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3041 * tconfig/sun3os4: Remove warning about native assembler,
3042 since it also occurs in the xconfig file.
3044 * findvar.c (registers): Allocate some slop after `registers'
3045 to prevent stray accesses from trashing the next variable.
3047 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3048 on the sun-3, by changing the #ifdef from `sun3' (which is not
3049 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3050 vars, which happened to follow `registers' in the executable.
3052 * readline/history.c (history_search): Heed gcc-2's advice
3053 and parenthesize && inside ||).
3055 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3056 tm-29k.c: Insert FSF copyright headers.
3058 * remote-eb.c: Better comments.
3060 * Makefile.dist: Update to 3.91.6.
3061 * TODO: note PREPARE_TO_STORE problem.
3063 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3065 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3067 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3069 * infrun.c (wait_for_inferior, at end): Don't set up
3070 prev_* if the inferior no longer exists.
3072 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3073 CANNOT_EXECUTE_STACK.
3074 valops.c (call_function): Use it.
3076 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3078 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3079 infrun.c (wait_for_inferior, 2 places): Use it.
3081 * values.c (value_being_returned): Only use
3082 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3084 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3085 right thing for remote-eb.c.
3087 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3088 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3090 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3091 (FRAME_FIND_SAVED_REGS).
3093 * findvar.c ({fetch,store}_registers): Check for
3094 REMOTE_{FETCH_STORE}_REGISTER macro.
3096 * findvar.c (get_saved_register): Add argument lval and
3097 change meaning of argument addr.
3098 findvar.c: Change calls to get_saved_register to reflect
3099 new calling convention.
3100 valops.c (value_assign): Use get_saved_register instead of
3101 find_saved_register.
3103 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3105 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3106 an (uninitialized) pointer to one. Use "&" when passing it
3109 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3111 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3114 * coffread.c (symbol_file_command): Put semicolon after
3116 Put safe_to_init_tdesc_context in #if defined (TDESC).
3117 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3118 coffread.c: #include <sys/stat.h>.
3119 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3120 Add missing ')' in check for "lc%" and friends. Remove
3122 Declare read_one_sym() at top of file.
3123 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3124 MC68WRMAGIC can have the same value without causing a duplicate
3127 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3129 * Allow a Makefile to be built without building the
3130 tm and xm file links that screw up builds in subdirectories.
3131 This is done with `config.gdb none', then you can do things
3132 like `make gdb.tar.Z'.
3133 * tconfig/none: Config file for no target system
3134 * xconfig/none: Config file for no host system
3135 * config.gdb: If no TM or XM files are called out by the
3136 host or target file, don't make links for them.
3138 * cplus-dem.c: Add documentation.
3140 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3141 simple error, so the user's gdb doesn't crash due to some object
3142 file problem (e.g. somebody is rebuilding the file out from under
3145 * printcmd.c (print_address_symbolic): demangle the symbol.
3147 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3148 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3149 (alldeps.mak): sort and uniq all results from this; duplicates
3150 hose gdb.tar.Z link building. Remove RCS files from
3151 tconfig and xconfig. Add config files for sun386. Add
3152 a few odd files to OTHERS and HFILES.
3154 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3156 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3157 Roll version number to 3.91.5. Make lint work in bindir.
3159 * README: Document cross-debugging and new file structure.
3161 * blockframe.c: Lint. Include "value.h" to declare read_register.
3162 (find_pc_partial_function): remove duplicate line.
3164 * command.h: Lint. Declare error_no_arg and dont_repeat.
3166 * tm-news.h: Remove inadvertently duplicated stuff.
3168 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3169 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3171 * config.gdb: Allow `config.gdb host target' form. Clean
3172 up previous change that printed bogus messages when you just said
3175 * core.c: #include "command.h" for lint.
3178 * main.c: Remove some casts of enums. Lint.
3185 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3187 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3188 read it from memory. This will allow us to save ptrace calls
3189 eventually. Changed caller single_step too.
3191 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3192 that we aren't going to use, saving many ptrace calls, especially
3193 when watchpointing or single stepping. Use some #define's for
3195 (store_inferior_registers): Ditto.
3196 (core_file_command): Use some #define's for constants.
3198 * tm-sparc.h: Add #define's for some register numbers, so we
3199 can eliminate the use of random constants in sparc-xdep.c.
3201 * stack.c (frame_command, print_frame_info, up_command,
3202 down_command) Remove frame_changed, since it
3203 causes a bug and doesn't seem to do anything useful. In some
3204 places it was used as a flag, in others as a stack level (?).
3206 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3207 default is to use the portable (vprintf) version rather than the
3209 * xm-news.h (MISSING_VPRINTF): Add.
3211 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3213 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3215 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3216 about linking debugged programs -Bstatic in the sun?os4 config
3217 files in tconfig and xconfig subdirectories.
3219 * main.c (main): Remove unreached exit(0) now that we exit
3222 * Create TODO file for online bug list. There are too many
3223 "little" bugs to keep track of on paper.
3226 rather than kingdon@ai.
3228 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3230 * Makefile.dist (VERSION): 3.91.4 now.
3232 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3233 (condense_misc_bunches): Add sanity check that misc_count is
3234 the same as the number of symbols in the bunch.
3236 * coffread.c: rename init_misc_bunches. Pass an argument
3237 to condense_misc_bunches (a zero).
3239 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3240 every time we are called; don't rely on our caller to do it.
3241 (add_file): Remove call to init_misc_bunches.
3243 * mipsread.c: Only warn, don't error, if unknown symbol types.
3244 This keeps an old gdb from falling on its face if it sees newly
3245 extended symbol info. Rename init_misc_bunches.
3247 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3249 * Merge in changes from Per Bothner for DECstations and other
3250 MIPS stuff. The rest is Bothner speaking:
3252 The next message is a merger of Alessando Forin's mips port with
3253 mine. I've tried to use my good if biased judgment to get
3254 the best of both. It *does* need testing.
3256 Some of the changes are general, *not* mips-specific.
3259 Didn't believe in little-endian bit order.
3260 There are still inconsistencies about whether flags
3261 like BITS_BIG_ENDIAN are integer (#if ...) or
3262 boolean (#ifdef ...). I tried to paper over them.
3264 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3265 Moved some misc_function code that was common to
3266 {dbx,coff,mips}read.c to symtab.c.
3267 In the process, I think I cleaned things up a bit.
3268 At the same time, moved obsavestring and obconcat to symtab.c.
3271 Removed obsolete condense_addl_misc_bunches (use
3272 condense_misc_bunches(1) instead).
3275 Needed to include <sys/dir>, at least on DECstations.
3277 valops.c, mips-tdep.c, tm-mips.h:
3278 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3279 conventions (when STACK_ALIGN is insufficient).
3280 Needed on mips, where doubles need 8-byte alignment,
3281 but ints only need 4.
3284 Removed cruft that was not being used.
3288 Print $ before register-names (I think that makes things a little
3290 Never print two instructions, even if one delays.
3291 Removed hex-disassemble set_cmd. (This is not mips-specific,
3292 so I think the argument is whether it is generally worthwhile or not.
3293 I'm inclined to think not, given how easy it is to
3294 convert between radixes in gdb.)
3297 This is basically Alessando's code.
3298 It doesn't use obstacks; I changed it to use obstacks
3299 in a few minor places where using malloc causes a
3300 memory leak. (Probably, more places could/should be changed.)
3301 I added record_misc_function where it was missing.
3302 In symbol_file_command and add_file_command, I tried
3303 to make the code consistent with more recent versions.
3304 Minor sylistic changes in parse_procedure.
3305 Make a .gdbinfo. psuedo-symbol point back to the real
3306 procedure symbol (using the isym field).
3309 This is basically from my port, but with a lot of details
3310 and a number of routines merged in from Alessando's version.
3311 I basically used my code "raw" backtrace (use heuristics
3312 from the actual code, rather than symbol table info) - though
3313 the idea is Alessandro's. I feel my code is a little cleaner
3314 here, particularly in being a little more flexible, such as being
3315 able to handle gcc-produced code (which it now can).
3316 It also doesn't do frame caching (which is not useful
3317 more recent gdb versions).
3318 I also used my code for push_/pop_dummy, more or less.
3319 I tried to incorporate AF's code for testing sigtramp
3320 while backtracing; I probably got it wrong.
3321 Added mips_print_register, which tries to scrunch as much
3322 information as possible on a screen...
3323 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3324 under mips-pinsn.c), I don't see anything mips-specific here,
3325 and I don't see it being all that useful anyway.
3328 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3329 Use more register names (rather than hard-cases numbers).
3331 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3333 * Hack up 3.90.11 changes:
3335 * Makefile.dist (depend): parameterize $(GCC).
3336 Add solib.c and solib.o.
3337 (readline): Fix vpath for both absolute or relative SRCDIR.
3340 Also, let the part I didn't understand at least compile so
3341 I can test the rest. FIXME.
3343 * dbxread.c: Fix thinko using strcmp.
3344 (init_psymbol_list): declare static.
3345 (partial_symbol_file_open): Comment cleanups better, avoid
3346 cleaning up the string table since the caller will do that.
3347 Move the stat for mod time into symbol_file_command, temporarily.
3348 (There should be a mod time for each symbol file, eventually,
3349 to control its rereading. FIXME.)
3351 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3352 SunOS, which gives error for shared libs otherwise. (From
3353 Schaefer, probably FIXME needs work for portability.)
3355 * solib.c: Move #include "param.h" to work.
3356 Lowercase all the Uppercase Letters In the Messages.
3357 (find_solib): Clean up inferior_so_name for debug printouts.
3358 Allow no argument, to mean all shared libraries.
3360 * symmisc.c: include param.h to get CLEAR_SOLIB.
3362 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3364 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
3365 to 3.90.11. ChangeLog entries below are from this.
3367 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3371 * Makefile.dist (HFILES): Add tm-sunos.h.
3373 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3377 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
3381 * sparc-opcode.h Added single-operand version of rett.
3383 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3385 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
3386 Put parens around gcc_p in expansion.
3388 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3390 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
3392 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3394 * Changes for Sun shared libraries:
3395 blockframe.c (find_pc_partial_function): If a non-text symbol
3396 is found, set *address = pc - FUNCTION_START_OFFSET.
3397 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
3398 Disable breakpoints instead of giving an error.
3399 source.c (select_source_symtab): Initialize cs_pst.
3400 symmisc.c: Call CLEAR_SOLIB if defined.
3401 symtab.h: Make text{low,high} CORE_ADDR not int.
3402 (psymtab): New field addr.
3404 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
3405 (record_misc_function): Give correct type for N_DATA symbols.
3406 (condense_misc_bunches): do "misc_function_count = j" regardless
3408 Take code which is shared between symbol_file_command and
3409 add_file_command and put it into partial_symbol_file_{open,read}.
3410 Split add_file_command into add_file_command and add_file.
3411 Make psymtab_to_symtab read in the string table if the file
3413 Two new parameters to read_dbx_symtab and start_psymtab.
3414 tm-sunos.h: New file.
3416 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3418 * infcmd.c: Change cont_command to continue_command and "cont"
3421 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3423 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
3425 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
3427 * values.c (USE_STRUCT_CONVENTION): Check for structures of
3428 size 1,2,4,8 rather than size < 8.
3430 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
3431 as necessary, not just once.
3433 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3435 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3437 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3439 * tm-news.h: Add CALL_DUMMY_*.
3441 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
3443 * config.gdb: In list_host, list_target, use ${i}, not $i.
3445 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3447 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
3449 * sparc-opcode.h: Change all store floating-point state register
3450 instructions to have the right match & lose fields.
3452 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3454 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
3456 config.gdb: If srcdir != ., create readline directory and
3457 copy a makefile into it.
3459 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
3460 consistency with POSIX.
3462 * breakpoint.c (bpstat_stop_status): Disable watchpoint
3463 when we exit its exp_valid_block.
3465 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
3467 * Makefile.dist: Bump version to 3.91.3.
3469 * Clean up handling of breakpoint commands (somewhat).
3470 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3472 inferior.h: Add breakpoint_proceeded to inferior status struct
3473 and globals; save it and restore it.
3474 (clear_breakpoint_commands): Cleanup, remove old #define.
3476 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3477 (save_inferior_status, restore_inferior_status): handle it also.
3478 (proceed): Remove earlier code that set breakpoint_proceeded.
3479 It is now set only in clear_proceed_status.
3480 (clear_proceed_status): Cleanup, use bpstat_clear rather
3481 than clear_breakpoint_commands. No callers need the stop_bpstat
3482 between clear_proceed_status and proceed.
3484 infcmd.c: Add breakpoint_proceeded definition and comment.
3485 (cont_command, jump_command, signal_command): Move call to
3486 clear_proceed_status right next to call to proceed.
3488 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3489 caller's argument while running down the chain of breakpoints.
3490 Use new variable "breakpoint_proceeded" to determine when
3491 a command that it executes moves the inferior past the
3493 (bpstat_clear): Handle NULL argument.
3494 (bpstat_clear_actions): Avoid useless call to
3495 breakpoint_auto_delete.
3496 (delete_breakpoint): Clean up bpstat's that are pointing to
3497 the deleted breakpoint from the stop_bpstat chain.
3498 (breakpoint_auto_delete): Simplify.
3500 * Clean up handling of EOF, error on stdin, etc. This was
3501 prompted by a network problem that caused gdb to go into an
3502 infinite loop filling up its malloc'd memory.
3504 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
3505 not clear_breakpoints_commands, which is now gone.
3506 (main): If command_loop returns (e.g. from EOF on stdin), do
3507 a quit_command (looping back to command_loop if quit_command
3508 doesn't really quit).
3509 (command_loop): check result from command_line_input and
3510 exit if it returns NULL, rather than passing the NULL to
3512 (gdb_readline): Free malloc'd result space before returning
3515 * utils.c (query): Handle C-d to mean "yes", just as if the
3516 input was not a terminal. Also avoid infinite loop if EOF
3517 occurs in mid-input-line before newline. This allows
3518 query to be used at EOF on stdin with reasonable results.
3520 * infrun.c (proceed): Set breakpoint_proceeded.
3522 * values.c (value_as_long): Avoid infinite recursion for enums.
3523 (_initialize_values): Fix typo in help msg (kingdon).
3525 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
3526 RL_LIB for linking. This allows -lreadline for linking
3527 and nothing for dependencies, once readline is a real library.
3529 * config.gdb: Jim Kingdon: give useful error message if the
3530 host or target type is not recognized.
3532 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
3533 it just defines it. Dumb, but deal with it.
3535 * Jim Kingdon suggests:
3536 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
3538 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
3540 * Makefile.dist (VERSION): Bump version # to 3.91.2.
3542 * Clean up Bothner's changes.
3544 * blockframe.c (clear_pc_function_cache): New function.
3545 * blockframe.c: remake cache_pc_function_* static.
3546 * dbxread.c (symbol_file_command): remove references to
3547 cache_pc_function_* variables.
3548 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
3549 * printcmd.c: Avoid kludging a global variable (addressprint)
3550 to avoid printing the address of a string twice. Instead,
3551 pass the format letter 's' down low enough that it can be seen
3552 to avoid this problem.
3553 (print_formatted): Pass format arg to value_print.
3554 (restore_addressprint): Remove function.
3555 (do_examine): Avoid hacking addressprint, cleanups and such.
3556 (print_frame_args): Add a comment to a Bothner change.
3557 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
3558 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
3559 to wipe out the values cached in blockframe.c.
3560 * symtab.c (find_method): Add comment saying how big you must
3561 allocate to be "big enough". Per being terse again.
3562 * valprint.c (val_print): Handle format letter "s" to print
3563 strings without addresses. Add comment to vtbl printing code
3564 which casts with wild abandon. Rearrange reference-printing
3566 @0xaddr: value (print w/addressprint)
3567 value (print w/~addressprint)
3568 @0xaddr (parameter lists w/addressprint)
3569 or nothing (parameter lists w/o addressprint)
3571 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
3573 * Merge more changes from Per Bothner:
3575 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
3576 annoying) that I tried to improve it. Here are my suggestions.
3578 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
3581 Do automatic de-reference when taking the address of a reference.
3583 Don't deref_ref when printing parameter lists.
3585 More attempts at treating refernences properly.
3587 In val_print, if deref_ref==0, don't print dangling " = ".
3589 Add COERCE_REF macro, which de-references an REF.
3591 * Merge changes from Per Bothner:
3593 * Fixed (Sony news)-specific configuration problems.
3594 * Fixed other problems with using vanilla pcc and libc (enum problems;
3595 assumption that vsprintf exists).
3596 * Some major speed-ups (finc_pc_partial_function now caches a match;
3597 parsing avoids duplicate symbol_lookup calls).
3598 * Changed handling of baseclasses (no longer use baseclasses field
3599 of struct type, use the first n_baseclasses fields instead).
3600 * Various minor changes/fixes, most C++-related.
3603 Cache the most previous match from find_pc_partial_function.
3604 (Save both low and high ends of matching function's pc range.)
3605 This speeds up the loop of infrun.c:wait_for_inferior quite
3606 a bit, and makes step/next commands much zippier.
3608 Added an enum->int cast (otherwise, some compilers barf).
3610 No longer set baseclass offset to 0, since multiple
3611 inheritance now mostly works.
3612 Added a number of casts, to shut up compiler warnings
3613 (after stabs where made enums, not ints).
3614 When discarding a symbol table (in symbol_file_command),
3615 must clear the cache introduced in blockframe.c.
3616 Don't convert $vtbl_ptr_type to vtbl any more.
3617 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
3618 Mask off sign bit emitted by g++ for virtual table offset.
3619 Set voffset to -1 (not 1) for static member functions.
3621 Changed parsing/lexing of names to avoid doing symbol lookup twice
3622 (once when lexing to determine symbol class, once for real).
3623 Now only call symbol_lookup once. Fields of 'this' win especially big.
3625 Subpress printing addr twice in the case of 'x/s addr'.
3627 lookup_basetype_type is no longer used.
3628 Add find_methods as recursive helper function to decode_line_1.
3629 This allows multiple inheritance to work.
3630 Also, once one or more matches has been found, do not look in
3631 base-classes. (Baseclass methods would be overridden, anyway.)
3633 Removed baseclasses array in struct type.
3634 Instead of using baseclasses[i], use fields[i-1].
3635 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
3636 Changed sign convention of voffset (previous was inconsistent).
3638 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
3640 Used to assume existence of vsprintf. Re-written to not need it
3641 if HAVE_VPRINTF is undefined.
3643 typecmp was too pessimistic. Made it less so.
3645 Don't print space after address.
3646 If vtable points to a misc symbol (with 0 offset), print it,
3647 since that indicates the actual class of the object.
3648 Changed ype_print_derivation_info to use new inheritance
3649 scheme (without baseclasses vector).
3651 In value_primitive_field, fixed some bugs left over from previous set of fixes.
3652 Also, changes needed because TYPE_BASECLASSES were removed.
3654 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
3656 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
3659 If there is no path set, and the symbols don't indicate what directory
3660 a file was compiled in, look in the current directory. But either
3661 a path or a known compilation directory will prevent this.
3664 Three independent bug fixes:
3665 * Remove the #if 0 block that breaks some stuff.
3666 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
3667 adapt gdb to either SunOS 4.0.* or 4.1.
3668 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
3671 Instantiate the class T when looking for methods in it. (Tiemann@sun)
3674 (type_print) Demangle the name being printed.
3675 (type_print_base) Handle botched demangling without coredump (tiemann).
3678 (check_stub_method): Document routine.
3679 (tiemann) fix bug for no-arg functions
3680 Avoid clobbering beyond end of malloc'd storage.
3681 Terminate the argument list properly.
3685 * Changes merged by John Gilmore:
3688 In breakpoint_1, use new print_address_symbolic instead
3689 of find_pc_partial_function. (This forces use of assembler-level
3690 addresses, and avoids misleading non-mangled source-level names.)
3692 Generalize ansi argument such that -1 means skip arglist totally.
3693 Removed global variable print_ansi_qualifiers (which made
3694 code non-reentrant), in favor of extra explicit arguments
3695 to internal routines.
3697 Add new helper function print_address_symbolic.
3698 Use find_pc_misc_function instead of find_pc_partial_function
3699 (since we want assembler-level symbols here).
3701 Print unknown function as just "f (...)", not "f (...) (...)".
3702 Use new fputs_demangled explicitly.
3704 Fixed a typing violation (problem: value.h cannot be imported
3705 without renaming many variable in this file).
3706 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
3707 decode_line_1: Moved forward some never-reached code.
3708 Made decode_line_2 skip function prologues correctly.
3710 fputs_filtered should not demangle by default.
3711 Add new fputs_demangled to demangle on demand..
3713 Change value_struct_elt to use value_primitive_field (using recursive
3714 utility function search_struct_field). This allows foo.bar to work
3715 for multiple inheritance (so far only for data fields).
3716 Change check_field in the same way (recursive helper function
3717 to support multiple inheritance).
3718 (Note: there are more of these problems that I haven't fixed.
3719 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
3720 value_of_this: 'this' symbol name is now just "this", note "$this".
3722 Don't print static members.
3723 Avoid printing "members of <type>" if there are none.
3724 Simplified type_print_derivation_info by merging duplicate code.
3725 Remove useless blank lines in type_print_base (ptype command).
3727 Added declaration of new routine value_primitive_field.
3729 Added value_primitive_field which is generalized version of
3730 value_field that can handle multiple inheritance (non-zero offsets etc).
3731 Re-implemented value_field to call value_primitive_field.
3733 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
3735 * infcmd.c -- insert else to avoid 'delete env' coredump when you
3736 delete the whole environment. Karl Berry reported the bug.
3737 * source.c - fix openp to avoid //'s in filenames, which
3738 trigger an Emacs bug causing it to not be able to find files
3739 when running gdb in a window.
3740 * dbxread.c - zap the #if 0 that botches the add-file code.
3741 It seems to work a lot better without all the code commented out.
3743 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
3745 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
3748 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
3750 * Makefile - added a ${CFLAGS} to a couple of entries,
3751 added remote-sa.sparc.c
3752 * added remote.sa-sparc.c, a modification of remote.c
3753 which conducts a dialog directly with the SparcStation prom.
3754 * breakpoint.c, infrun.c, sparcdep.c added
3755 remote_insert_breakpoint(), and remote_remove_breakpoint()
3756 to breakpoint.c instead of directly writing breakpoint instructions.
3757 * sparcdep.c on remote_debugging,there is no need
3758 to remove signle step breakpoint instructions.
3759 * main.c added "-epoch" flag and "int epoch_interface" to main.c
3761 * printcmd.c - epoch interface sends lisp expressions to open up
3762 epoch windows on inspection.
3763 * valprint.c - added arrayprint, and addressprint and made adding
3764 format controls easier
3765 * wait.h added a couple of undef's because we were getting
3766 complaints about WSTOPSIG and WTERMSIG begin redefined.

3791 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
3793 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
3794 should print ANSI qualifiers (such as `const' and `volatile').
3795 All callers changed to call with ANSI == 1, except from
3796 `check_method_stub', which uses old-style syntax.
3798 * symseg.h (struct fn_field): Remove unneccessary `args' field.
3799 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
3801 * values.c (check_stub_method): New function.

3820 * blockframe.c (blockvector_for_pc): New function.
3821 * blockframe.c (block_for_pc): Changed to call
3822 `blockvector_for_pc' and get the block itself.
3824 * stack.c (catch_info): New function. Prints info about
3825 exceptions which can be caught in the current frame.
3826 * stack.c (print_frame_label_vars): New function. Similar to
3827 `print_frame_local_vars'.
3828 * stack.c (print_block_frame_labels): Prints out labels that are

3836 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
3837 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
3838 when printing the type.
3840 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
3842 * valprint.c (val_print): Use `baseclass_addr' to access the
3843 baseclasses pointed to via the derived class object at VALADDR.
3845 * values.c (baseclass_addr): New function. Casts derived pointers

3855 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
3856 exp_valid_block field correctly.
3858 * infrun.c (wait_for_inferior): When checking "don't even think
3859 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
3860 also check step_resume_breakpoint.
3861 Insert breakpoints and continue (not step) if
3862 step_resume_break_address != NULL, even if another_trap.
3863 If trap_expected and we enter sigtramp, then set up a
