3 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
4 applied various small fixes due to or inspired by RMS comments
6 * doc/gdb.texinfo: finished using all RMS comments, save those for
7 appendices on readline and cmd history (which are in other source
10 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
12 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
13 chapter 9; (2) documented 'break' command's menu mode for
14 overloaded names, in response to hgs problem report C++ p-31

22 instructions to "Targets" chapter for generic manuals, while
23 leaving them up front for manuals specific to specialized
24 environments; (6) apply fixes from RMS comments through chapter 4.
26 * pretex.m4: modify explanatory text slightly (and redefine
27 "regexp") to keep GNU m4 from complaining. (It still crashes

48 locally for release. These are ordinary info
49 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
50 Makefile)---but due to use of texinfo 2, can't count on makeinfo
51 to generate these, so we distribute them already formatted.
53 * gdb.texinfo: included full Info node and menu crud (as generated
54 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
56 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
57 put in comments-for-future gdb.info target (one day makeinfo will

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

500 before returning locals or slocals.
502 * i386-tdep.c (i386_follow_jump): Do not add data16 to pos in
503 call to codestream_seek; add one to pos if (and only if)
504 we are dealing with a jump with data16 == 1 (i.e. 0x66, 0xe9).
506 Mon Apr 15 12:04:32 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
508 * valops.c (call_function_by_hand): Put dummy1 in target order

534 tm-sun3.h: Define TARGET_SUN3.
536 * utils.c: Use CPLUS_MARKER not '$'.
538 * cplus-dem.c: Use CPLUS_MARKER not '$'. If CPLUS_MARKER isn't
539 defined, define it to '$'.
541 * arm-opcode.h: New file (same contents as before; it had
542 just been left out of the distribution for a long time).
544 * tm-68k.h: Put declaration of ext_format_68881 outside the macros.

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

605 (_initialize_main): Rename "info version" to "show version".
607 * values.c: Rename value_history_info to show_values.
608 (_initialize_values): Rename "info values" to "show values".
610 Sun Apr 14 23:08:34 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
612 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
613 New function to give correct error message.
615 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
617 * target.h: Add to_doc and target_preopen.
618 target.c: Add target_preopen and target_command.
620 (add_target): Call add_cmd and mess with targetlist->doc.
621 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
622 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.

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

1001 aren't the mainline. Free the "info" struct since we're done with
1003 (init_psymbol_list): Free any previously allocated psymbol lists.
1004 (): FIXME: Should realloc-down the psymbol lists when done reading
1005 the main symbol file?
1007 * symmisc.c (free_symtab): Free fullname field too.
1009 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1010 (REGISTER_ADDR): Make result type unsigned int.
1012 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1013 define REGEX must also define REGEX1 (its dependency).
1015 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1017 * tconfig/i960: No longer works, points you at vxworks960 or

1034 (object search path) as conveniently as the source search path.
1035 * environ.c (set_in_environ): Set some vars in GDB's environment,
1036 in addition to the child's. PATH, G960BASE, G960BIN for starters.

1050 in raw hex as well as float format, regardless of whether it is
1051 a "virtual" convertible register.
1052 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1053 regs as a double, just in case it's being used that way.
1054 * values.c (unpack_long): Comment on array/function coercion.
1055 (unpack_double): Argument is in target byte order now. For
1056 integer arguments, just call unpack_long and float the result.
1057 * m68k-tdep.c: include defs.h for "const" handling.
1058 * remote-nindy.c: Use ieee-float stuff.
1059 (nindy_fetch_registers): Unpack double regs to host double, then

1073 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1075 * coredep.c (fetch_core_registers): Pass end-address of register
1076 section to register_addr as expected. Don't call supply_register
1077 if we'd just pass it garbage.
1079 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.

1126 * inftarg.c (child_detach): Pop the child_ops vector if the
1127 detach is successful.
1128 * remote-nindy.c (nindy_create_inferior): Don't push a new
1129 nindy_ops since nindy uses the same one for execution and memory
1131 * core.c (core_ops): Use child_attach and child_create_inferior
1132 rather than default attach and create_inferior functions.
1134 Handle floating point registers in core files.
1136 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1137 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1138 This version untested since BFD doesn't yet support sun3 core
1140 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1141 conventions. Fix comments and style. This version has not
1142 been compiled yet, since we have no HP inhouse.
1143 * core.c (get_core_registers): Look for two sections, ".reg"
1144 and ".reg2", and pass both to fetch_core_registers sequentially.
1146 Revise directory path yet again.
1148 * source.c (forget_cached_source_info): Not static any more.
1149 (init_source_path): New default source path is "$cdir:$cwd".
1150 (dir_command): Handle variable arguments ($cdir, $cwd).
1151 (source_info): Print "Compilation directory" rather than
1152 "Originally compiled in" to remind people of $cdir.
1153 (openp): If the path contains $cwd, use current directory.
1154 (open_source_file): If compilation directory is known, replace
1155 first $cdir in path with the compilation directory.
1156 (print_source_lines): Even if we can't print the lines, set the
1157 current symtab and line for future commands like "info source" or
1158 "breakpoint". Also, error message now contains the file name,
1159 line number, and file access error message.
1160 (_initialize_source): Fix help text to describe changes.
1161 * main.c (cd_command): Forget cached source info when we chdir.
1162 * utils.c (strstr): Add simple implementation.

1166 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1167 Byte-swap COFF symbol tables if necessary when reading them in.
1168 Use complain() to replace error message in one spot. Needs
1169 corresponding change in bfd/coff-code.h to make some symbol
1170 swapping routines non-static.
1172 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)

1182 declarations of errno.
1184 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1186 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1187 <rpc/rpc.h> and <rpc/types.h>.
1189 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1191 * i960-tdep.c (examine_prologue): Add new argument limit,
1192 which stops the scan at the end of the prologue, or at the PC.
1193 This fixes a problem where it walks down into the code for the
1194 user's statements if that code looks like function prologues.
1195 Mark Fox and I have been bouncing this code back and forth, making
1196 small changes to it. Callers changed to match.
1198 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1200 Cleanup for gdb-3.94 release final:
1202 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1203 the .c files from vx-share and nindy-share, from the various
1204 macros, since they are not found via ALLDEPFILES.
1205 (SFILES): Add tm-i960.h.
1206 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1207 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files

1214 * am29k-tdep.c: Add contribution line.
1215 (examine_prologue): Cache information about function prologues in
1216 the misc-function-vector to avoid lots of references over the
1217 serial line while examining instructions.
1219 * core.c (core_close): New function made from cleanup_core.
1221 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1222 remote-vx.c, remote.c, target.c, target.h,
1223 Update target_ops vector to add attach, close, and load entries.
1224 Use add_syms_addr_command, not add_file_addr_command, for
1225 add_file. Break out close routine from existing code.
1227 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1228 they are in an obstack.
1229 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1231 (define_symbol): Add symbol type parameter; change callers;
1232 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1233 it to influence the symbol class on the i960.
1234 (define_symbol): Swap LOC_CONST's into target byte order.
1236 * exec.c (exec_close): New function.
1237 (exec_file_command): Call it.
1239 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1240 Fix byte order of frame pointer.
1241 (read_var_value): Result of 0 if var's value can't be found,
1242 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1243 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1244 (locate_var_value): Use read_var_value and use its lazy address
1245 as the location of the var's value. Lint.
1247 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1250 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1251 obsolete Intel versions in favor of vxgdb versions.
1252 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1253 code dealing with byte order of values, which Intel did in host byte
1254 order rather than gdb-4's target byte order.
1255 (i960_frame_chain_valid): Move to nindy-tdep.c.
1256 (examine_prologue, skip_prologue, frame_find_saved_regs,
1257 frame_args_address, leafproc_return, saved_pc_after_call,
1258 pop_frame): Add vxgdb versions from Mark Fox.
1259 (examine_prologue, frame_struct_result_address): Add code
1260 to deal with the saved value of G13 (struct return address
1262 (frame_args_address): Modify Mark's version to prefer the
1263 saved value over the current value in the topmost frame.
1264 Cache result in the frame info to avoid performance hair in
1266 (print_fault): Add gdb960 code for printing faults.
1267 (_initialize_i960): Actually call check_host.
1269 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1270 add stub routines. FIXME, these currently just return zero!

1273 (attach_command): Call target_attach, not target_open, now.
1275 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1276 (child_attach): Rename from child_open.
1277 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1278 don't confuse it with a zero step_resume_break_address.
1280 * inftarg.c (child_detach): Eliminate inferior_pid test.
1281 (child_files_info): Clean up message a bit.
1282 (child_ops): Use child_attach, not child_open, to attach.
1284 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1285 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1286 findvar.c to here, since it depends on the contents of the
1287 shadow_contents of breakpoints, but keep if #if 0 since it is
1290 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1293 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1294 (ptype_command, display_command): Eliminate have_inferior_p and
1295 have_core_file_p in favor of target_has_stack or
1296 target_has_execution.
1297 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1298 code for actually finding the values of arguments, though we still
1299 keep track of the maximum stack offset for use in printing unnamed
1300 arguments. Handle missing FRAME_ARGS_ADDRESS.
1302 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1303 (struct nindy_regs): Define registers passed to/from nindy.
1304 (nindy_fetch_registers, nindy_store-registers): Translate between
1305 nindy and GDB formats for the registers.
1306 (dcache_init): Statically allocate the cache, since it was being
1307 allocated by a malloc that was never freed anyway.
1308 (nindy_create_inferior): Error, not core dump, if no exec file.
1309 (nindy_before_main_loop): Use target_load, not target_add_file.
1311 * remote-vx.c (net_load): Specify large timeout for load
1312 requests. Allow user to break out with INTERRUPT.
1313 (net_break): Remove useless code, clean up. Change callers.
1314 (parse-args, skip_white_space, find_white_space): Clean up arg
1315 parsing to cope with quoted strings.
1316 (net_wait, net_quit): Never call error, just return status.
1317 (vx_read_register, vx_write_register): Cleanup status checking.
1318 #ifdef the code based on which CPU we are using (960 or 68k),
1319 FIXME, this should be completely general but it isn't yet.
1320 (vx_xfer_memory, vx_resume): Cleanup status checking.
1321 (vx_run_files_info): Improve message.
1322 (vx_load_command): Renamed from vx_add_file_command. Allow load
1324 (net_ptrace): Remove unused routine.
1325 (vx_wait): Adopt code from vxgdb960 to cope with broken
1326 connections to target machine and prompt to disconnect. Remove
1327 debug printouts. Map some EVENT_'s to SIGnals.
1328 (add_symbol_stub, vx_open): Print names of object files we found,
1329 and "ok" if we read their symbols OK. Clarify output in general.
1330 (vx_attach, vx_detach, vx_kill): Add these commands.
1331 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1332 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1333 "info files" output, and create_inferior, since we already have
1336 * stack.c (frame_info): Replace Frame_unknown with 0.
1337 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1338 (return_command): Pop until the PC matches as well as the FP,
1339 so it works even if the FP is shared with another function,
1340 as in "frameless" or "leaf" procedures.
1342 * symfile.c (load_command): renamed from add_file_target_command.
1343 (add_syms_addr_command): renamed from add_file_addr_command.
1344 (add_syms_command): Stub to call target_add_syms.
1345 (_initialize_symfile): Change command names and descriptions,
1346 add-file => add-syms, and load from alias to its own command.
1348 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1349 maybe_kill_then_create_inferior): Default for attempts to start
1350 a process, if one is already running, is to ask about killing
1351 it and retry if yes.
1352 (upstack_create_inferior): #if-0 it, strata obsolete it.
1353 (push_target, unpush_target, pop_target): to_close() a target
1354 before unstacking it.
1355 (target_info): Renamed from target_files_info.
1356 (_initialize_targets): Rename "i files" as "i target", accessible
1359 * target.h: Improve comments about the target_ vectored routines.
1361 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.

1364 (SKIP_PROLOGUE): No longer a no-op.
1365 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1366 (*_REGNUM): Sort register numbers.
1367 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1368 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1369 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1370 are now 10 byte extendeds, not 8 byte doubles.
1371 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1372 for nindy versus vxworks targets. FIXME, this should possibly go
1373 in the target vector.
1374 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1375 frame_saved_regs and arg pointer with each frame.
1376 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1377 (FRAME_ARGS_ADDRESS): Use cached result.
1378 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1379 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1380 (PRINT_RAMDON_SIGNAL): Call print_fault.
1381 (POP_FRAME): Now works.
1383 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1384 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1385 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1386 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1389 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1390 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1392 * valarith.c (value_subscripted_rvalue): Avoid handling
1393 floats and doubles specially; it gave alignment errors. Lint.
1395 * valops.c (value_of_variable, value_of_this): Error if unknown
1398 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1399 to avoid alignment problems.

1402 (val_print): Use unpack_long rather than pointer-deref.
1405 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1406 to avoid alignment problems.
1407 (value_being_returned): Error if return value unknown.
1408 (set_return_value): Add bogosity warning, FIXME. *
1410 * TODO: A woman's work is never done.
1412 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1413 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1414 Add ieee-float.o to OBS.
1415 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1416 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1417 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1419 Changes to generalize the VxWorks RPC protocol slightly, to handle
1420 i960 as well as 68000.
1422 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1423 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1424 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1425 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1426 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1427 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1428 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1429 so they will move in target byte order rather than network
1430 byte order (happens to be the same).
1432 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1434 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1436 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1439 Add contribution lines to various files, showing where they
1442 * breakpoint.c (break_insn, check_break_insn_size,
1443 read_memory_nobpt): Remove to mem-break.c.
1445 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1448 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1449 entry has bad register number. This change is not
1450 tested in this release, FIXME.
1452 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1455 * value.h: Force value's contents field to be aligned to hold
1456 at least a double or a long long (if supported). This avoids
1457 doing bcopy's in and out of the contents field.
1459 (step_1): Avoid coredump under obscure circumstances when we
1462 * symtab.h (misc_info): Add field to misc function vector for
1463 any kind of cached information the target code desires. AMD
1464 29000 uses this to avoid repeating examine_function_prologue's.
1466 * coffread.c: Lint. Remove static symfile, read_section_header.
1467 core.c (have_core_file_p): Lint: remove.
1468 expprint.c (print_subexp): Lint.
1469 infptrace.c, valops.c, valprint.c: lint.
1471 Roll in changes from vxgdb-5.0.1:
1473 * symtab.h: Comment byte order of each address class. Add
1474 LOC_LOCAL_ARG for frame-relative args (960).
1475 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1476 symtab.c, symmisc.c: ditto.
1478 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1480 * remote.c (remote_resume): Error if resume with a signal.
1482 * symfile.c (prim_record_misc_function): Clear misc_info.
1483 (fill_in_vptr_fieldno): Check stub type of arg.
1485 * valops.c (value_cast): Avoid looking up names of types whose
1486 name we don't know, to prevent coredump. Sun CC produces typedef
1487 rtx and the name of *rtx is zero...
1489 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1491 Roll in changes from final AMD 29000 port (Tiemann).
1493 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
1494 for ../include/a.out.encap.h. This might not work now that BFD
1495 is separately compiled. Instead, BFD support for encap will have
1496 to translate machine type 29k into the right COFF_MAGIC.
1498 * infcmd.c: Remove references to inferior_pid that aren't used
1499 in actual ptrace calls; use target_has_execution, etc.
1500 (have_inferior_p): Remove function.
1501 (program_info): Print target info rather than "process number";
1502 avoid gratuitous messages unless from_tty.
1503 (run_stack_dummy, finish_command): Set proceed_to_finish.
1504 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
1505 main.c: Lint. Lose have_inferior_p().
1506 inferior.h (have_inferior_p): Remove, lint.
1507 (proceed_to_finish): Add flag to ask that all regs be saved
1508 by normal_stop, for the few commands that need it, speeding up
1509 serial I/O. Add comments to stop_registers.
1511 * remote-eb.c: Remove newline from breakpoint message we grep
1512 for. Never time out when running the user program.
1516 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1518 Roll in changes from vxgdb-5.0.1:
1520 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
1521 symbol in its raw form, we are processing an unlinked ".o" file.
1522 See if the target environment has assigned it an address, using
1523 target_lookup_symbol (VxWorks does), and enter it into the symtab
1526 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
1527 68k versions for a simpler version that assumes zero FP at bottom.
1528 Fixes bug of truncated stack reports.
1530 * target.h (target_lookup_symbol): Define this routine's args
1531 and result, finally.
1533 * target.c (nosymbol): Default routine for target_lookup_symbol.
1534 (target_default): Default lookup_symbol and call_function too.
1535 (files_info): Only print has_all_memory warning if a non-dummy
1538 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
1539 vx_convert_from_virtual): If target does not have floating point,
1540 zero register "values", and avoid doing cross-net conversions.
1541 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
1542 (vx_open): Rearrange code that attaches to target and reads
1543 symbols for all loaded modules, to work if some of the modules
1544 are not accessible. Add symbol_stub() and add_symbol_stub()
1545 as callbacks from catch_errors(). Allow connect attempt to be
1546 interrupted painlessly with ^C (FIXME, there are still some bugs
1547 if the interrupt happens during symbol reading.). Print
1548 final message with puts_filtered, since symbol messages are
1553 * main.c (catch_errors): Only print errstring if non-null.
1554 (command_loop): Avoid an ioctl per command to test ISATTY.
1556 * remote-vx.c (net_load): make static; avoid sophomoric msg.
1557 (vx_xfer_memory): Return correct result!
1558 (vx_files_info): Indicate whether target has float or not.
1559 (vx_lookup_symbol): Complain, not error, if target gone.
1560 (vx_open): Print "Connected" msg before disabling immediate-quit.
1561 [FIXME: lookup_symbol and vx_open changes need testing.]
1563 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
1564 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
1565 contributor lines and update copyrights to 1991.
1567 Changes from an attempted H-PUX host port:
1569 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
1570 defines PT_ATTACH and PT_DETACH but not PT_KILL.
1571 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
1572 * remote-vx.c: include <sys/time.h> for HPUX.
1573 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
1574 "core_file_command" routine to BFD regime. May not work yet.
1576 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
1578 * xgdb.c: Replace X10 version with some VJ version.
1579 (FIXME: Its copyright assignment is not on record.)
1580 * xgdb.c: Update include files to X11R4 (Xaw crud).
1581 (xgdb_display_source, create_text_widget): fix call to
1582 get_filename_and_charpos. Rewack source window stuff for X11R4
1583 (gleaned from include files, and "nm's" of binary libraries, since
1584 I had no doc available).
1585 (append_selection, append_selection_word): Disable with FIXME
1586 since R4 changed interface here.
1587 (create_buttons): Add back the old set of buttons.
1588 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
1590 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
1591 Roll VERSION to 3.94 (not yet final though).
1593 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1595 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
1596 obstack_int_grow, obstack_int_grow_fast): Eliminate
1597 cast on left of assignment, which gives MIPS cc fits and is
1600 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
1601 F_ALIAS. Use printf, not fprintf, when not passing a file
1603 (compare_opcodes): Check that identical instructions have
1604 identical opcodes, complain otherwise.
1606 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
1607 was reported by Roland McGrath.
1608 (unimp): Only match if exactly zero instruction. (Roland)
1609 (branches and traps): Generate all variations of these
1610 instructions with macros, based on a single call that defines
1611 each condition name and its binary representation.
1612 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
1614 * valprint.c (val_print_fields): Take, and use, format parameter.
1615 This means that "p/x struct" again prints the elements in the
1616 desired format. Changed callers.
1618 * stack.c (frame_info): Use filtered output, and indicate wrap
1619 points. Remove kludgy formatting designed to avoid line wrap.
1621 * utils.c (wrap_here): If the line is already full (because
1622 we had printed a long indent or long wrapped string), do an
1623 immediate newline-and-indent.
1625 * m68k-pinsn.c (print_insn_arg): Bugfix from
1626 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
1627 instruction is incorrectly disassembled as bkpt #8.
1629 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
1630 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
1631 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
1632 and then will dump core (sometimes). I traced it back to an
1633 uninitialized symfile_name in psymtab_to_symtab.
1634 (const_vol_complaint): Add quotes to message.
1635 (define_symbol): Only believe line number if gcc_compiled.
1636 Avoid allocating symbol if we will not return it.
1638 Add target strata support so that newly established targets go
1639 into their right place in the target stack (e.g. a new exec file
1640 doesn't wipe out the ability to access the running process).
1642 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
1643 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
1644 and initialize it properly in all the targets.
1646 * target.h: Document strata. Change return type of push_target.
1648 * target.c (nomemory): new function for dummy memory access.
1649 (tcomplain): Rename complain, now also used in symfile.c.
1650 (push_target): Push targets within strata. New return value shows
1651 whether new target is on top of stack or not. Always keep dummy
1653 (target_files_info): Ignore dummy target.
1655 * core.c (core_open): Warn user, and skip accessing file, if the
1656 core target is not the topmost target in the stack.
1657 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
1660 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
1661 target_ops, it doesn't belong there since we have no regs there.
1662 Change name of target from machine => memory to clarify.
1664 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
1666 * Freeze version 3.93 for release.
1668 * Makefile.dist: Handle vx-share and nindy-share subdirs
1669 properly when building gdb.tar.Z.
1671 * symtab.c: lint; add no_symtab_msg to consolidate the messages
1672 printed in various places, so I could change just one copy.
1674 * dbxread.c, coffread.c: Change references to bfd->iostream
1675 to cast to FILE *, now that BFD avoids needing types defined
1676 in other header files.
1678 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1680 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
1681 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
1682 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
1683 (actually gcc -Wall).
1685 * dbxread.c: Remove first_global_sym, last_global_sym, since
1686 they are never referenced.
1688 * defs.h (baud_rate): Declare.
1689 main.c: Define it, and add the -b option to set it.
1691 * gdb-int.texinfo: Add text on how to define a new host or target
1692 architecture, prompted by Per Bothner's questions about MIPS
1695 * gdb.texinfo: Document "complaints". Change doc of -q since
1696 gdb no longer prints the copyright and blurb if you specify a file
1697 name to be debugged (just like Emacs). Add doc for Nindy-specific
1698 command line flags for specifying target serial port and such.
1699 Update copyright to 1991.
1701 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
1702 has taken over for us the job of ripping up executable files. The
1703 crud caused Per Bothner's port to not compile.
1705 * infrun.c (normal_stop): Avoid printing "Program exited
1706 normally" if we are in batch mode. This allows a GDB which
1707 executes a program on a target system, to behave like a Unix
1708 command (input from stdin, output to stdout, no extraneous
1711 * main.c (main): Allow additional machine-dependent command line
1712 options to be specified with the ADDITIONAL_OPTIONS,
1713 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
1714 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
1715 processing to occur just before the main loop with
1716 BEFORE_MAIN_LOOP_HOOK.
1717 (main): If a "core file" argument is specified, and it is not a
1718 core file, try it as a process ID to attach.
1719 (symbol_completion_function): Attempt to cope with
1720 "show screen-" TAB, not very successfully. This needs more work,
1722 (batch_file): New function, returns whether we are reading
1723 commands from an interactive tty on stdin, or from somewhere else.
1724 Called by normal_stop since it doesn't get from_tty passed down
1725 to it like many commands do.
1727 * remote-nindy.c: Handle command line options for nindy
1729 (nindy_before_main_loop): Prompt user for tty name if they
1730 don't specify it before getting to the interactive command loop.
1732 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
1733 and -r command line options. Also add hook before main loop
1734 to make it easy to specify a tty.
1736 * TODO: More things to do, one done.
1738 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
1740 * dbxread.c: Make complaint() calls pass pointer, not struct.
1741 Add complaints about badly formatted C++ type information
1742 (const/volatile indicator, and parse errors resulting in
1743 error_type). Fix C++ virtual member fn comment.
1744 (read_struct_type): Avoid bumping pointer if we got a parse
1745 error; this prevents our walking beyond the end of a string.
1746 Terminate loop on null char as well as semicolon.
1747 (process_one_symbol): Fix the LBRAC fix so that it uses the
1748 last previous SLINE, FUN, or SO record's PC address. C++ debug
1749 symbols did not have SLINE records in a useful order compared
1750 to the LBRAC records.
1751 (define_symbol): Handle "catch" records.
1753 * symtab.c (check_stub_type): Added new complain
1754 `stub_noname_complain' and added a consistency check to
1755 keep the debugger from crashing when finishing from an
1756 exception frame. A real fix will be needed later.
1758 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1760 * infcmd.c (attach_command): Make global.
1762 * Makefile.dist (REMOTE_OBS): Make these compile by default,
1763 but make them easy to comment out. Perhaps later they should
1764 be enabled by what CPU you configure for? FIXME.
1765 (VERSION): Roll to 3.93.
1766 (pinsn.o): Remove rule for obsolete file.
1767 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
1769 Run down a problem that manifested by printing the wrong function
1770 name in stack traces of read_ofile_symtab. Turned out that the
1771 problem was the SunOS 4.1.1 (and previous) C compiler outputs
1772 the LBRAC symbol with an address in the *data* segment, which
1773 blew our binary search through the blocks.
1775 * dbxread.c: Use the complain() facility consistently to bitch
1776 about problems in the symbol file we are reading.
1777 (finish_block): Add code to check the nesting of the blocks;
1778 complain and Procrust them to fit if wrong.
1779 (make_blockvector): Check the order of the blocks, complain
1780 [but don't cope] if wrong.
1781 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
1782 symbols to be sure their PC value is greater than the last SLINE
1783 (line number) symbol we've seen, complaining and adopting the
1784 SLINE PC value if wrong.
1786 * symfile.h (struct complaint, complaint_root, complain,
1787 clear_complaints): Add.
1788 * symfile.c (complain, complaint_root, clear_complaints): Add
1789 facility to deal with non-fatal complaints and to regularize their
1791 (symbol_file_add): Clear complaint counters to allow new complaints.
1792 (initialize_symfile): Add 'set complaints' and 'show complaints'.
1794 * dbxread.c (dbx_symfile_read): Remember the address and size
1795 of the string table for the main symbol file, so we won't read it
1797 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
1798 to avoid reading the string table yet again. Lint.
1799 (throughout): Improve filtered output, including word wrap.
1800 (read_range_type): Improve Bothner's fix to handle other types too.
1802 * utils.c: Improve line wrap implementation. Handle unlimited
1803 width by making chars_per_line unsigned.
1804 (puts_filtered): New, easy, function.
1806 * defs.h (puts_filtered): add.
1808 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
1809 call the identical sort_symtab_syms() in symfile.c instead.
1811 * expread.y: Suggest the `file' command rather than `symbol-file'.
1813 * command.h (enum var_types): Add zinteger for seroable
1815 * command.c (do_setshow_command): Handle var_zinteger. Restructure
1816 nested if's into a switch.
1818 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
1819 we did not stop because of a breakpoint (it must have been for
1820 some other reason, like a "stepi"), so don't print anything.
1822 * symtab.c: Include <sys/types.h> all the time. Now that BFD
1823 doesn't include <sys/types.h>, old SunOS's require it for
1826 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
1828 A test port of gdb-3.92.6 to the Sony NEWS.
1831 Don't normally link in remote- or vx stuff.
1832 Some of it doesn't compile, and it wastes space for 99% of the users.
1833 Remove reference to no-longer-used HAVE_VPRINTF.
1834 Fixed BFD_DEP typo to BFD_DIR.
1836 Fix cast in arg to bfd_h_getlong.
1837 Make char *prefix be const.
1838 Fix how certain range types are mapped into builtin unsigned int types.
1840 Remove 2 #includes. They cause errors (on Sony, at least),
1841 and aren't needed (they wern't in earlier versions).
1843 print_address_symbolic should never demangle labels
1844 (since it prints *assembler-level* labels).
1846 [This was superseded by the change to printcmd below.]
1849 Add some "volatile" return types to avoid warnings.
1850 If MISSING_VPRINTF add vprintf function and not just macro
1851 (since vprintf is used in printcmd.c).
1853 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
1854 (The latter isn't grokked by some PCC-based compilers.)
1856 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
1858 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
1859 * nindy-share/coffstrip.c
1860 Added some forward declarations (otherwise, gcc complains
1861 about implicit extern redefined as static).
1863 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1865 Changes inspired by Per Bothner:
1866 * printcmd.c (print_address_symbolic): Take additional parameter
1867 specifying whether to demangle.
1868 (print_address): Pass in asm_demangle to control demangling.
1869 (print_address_demangle): New fn, takes explicit arg to control
1871 * utils.c: Add new vars demangle and asm_demangle, and let them
1873 (fputs_demangled): If !demangle, just print the argument.
1874 (fprint_symbol): If !demangle, just print raw symbol.
1875 * valprint.c (val_print): Call print_address_demangle rather than
1876 print_address, to cause demangling to depend on the global
1877 rather than assembler-level demangling setting.
1878 * WHATS.NEW, gdb.texinfo: Document.
1880 * main.c (show_command): Show all settings if no arg.
1881 (initialize_main): Make "info set" the same as naked "show".
1882 * command.c (cmd_show_list): Handle prefix commands in the
1883 list, and print the name of the setting as well as its English
1884 description and value.
1886 Allow gdb functions to specify where a line should wrap if it
1887 exceeds the size of a terminal line. Use it to make the output
1889 * utils.c (set_screen_width_command): New fn, mallocs a buffer
1890 of the right size when screen width changes.
1891 (set_screensize_command, screensize_info): Remove #if 0'd fns.
1892 (wrap_here): New fn, indicates a point in the output where we
1893 should wrap the line rather than just letting it overflow at a
1895 (fputs_filtered): Implement wrapping.
1896 (n_spaces): New fn, returns a pointer to N spaces.
1897 (print_spaces_filtered): Use n_spaces.
1898 * defs.h (n_spaces): Declare.
1899 * stack.c (print_frame_info): Wrap with 4-space indent after
1900 fn name and before filename and line number.
1901 * printcmd.c (print_frame_args): Wrap with 4-space indent
1902 before each argument name is printed.
1903 * valprint.c (value_print): Wrap with no indentation before
1905 (val_print_fields): Wrap with indentation relative to nesting
1906 level before each field name.
1907 (val_print): Wrap with nesting indentation before array elements.
1908 * command.c (do_setshow_command): Avoid extra newlines,
1909 wrap with 4-space indent around values printed, end with period.
1910 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
1912 * breakpoint.c (breakpoint_1): Implement addressprint for
1913 "info breakpoints" display. Change file name and line number
1914 format to " at file:nnn" rather than " (file line nnn)".
1915 * gdb.texinfo: Document.
1918 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1920 Frozen for gdb-3.92.6 release.
1922 README, WHATS.NEW: Update for 3.92.6 release.
1924 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
1925 coffread.o from configs since it is now built by default.
1926 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
1927 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
1928 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
1929 from configs since it is now built by default.
1931 Makefile.dist: Update for release 3.92.6. Handle files that
1932 have been moved to ../include, ../getopt, or ../bfd. Add
1933 saber.suppress and tests directory. Add config.status to
1934 the release (it will say "none").
1936 coredep.c: Minor formatting fixes.
1938 These changes were made in early December but only checked in now:
1939 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
1940 nindy-share/nindy.c: lint
1941 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
1942 register values coming back from the target; we store values
1943 in target byte order everywhere.
1945 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
1947 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
1949 * valprint.c (cplus_val_print, val_print_fields): New functions,
1950 which print C++ objects. They conspire to avoid printing a
1951 virtual base class more than once, following all the twists and
1952 turns of C++ virtual base rules.
1953 (val_print): Call the above rather than do it by hand.
1955 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
1956 symbol file, not for added files like shared libs. This really
1957 needs to be generalized to a timestamp per file.
1959 * core.c (cleanup_core): Avoid coredump if no core file.
1961 * config.gdb: Accept -host or -target in place of +host or
1964 * coffread.c (find_linenos): Avoid desupported BFD interface
1965 to line numbers. We still read them manually rather than using
1966 BFD's "generic" features.
1968 * gdbrc.tex, threecol.tex: Add GDB reference card and its
1970 Makefile.dist: Add refcard to OTHERS list for creating tar files.
1972 * Makefile.dist: Eliminate use of $< in explicit targets.
1974 * readline/Makefile: Use $< rather than $*.c, which does not
1975 include the VPATH in GNU Make.
1977 * tconfig/i960-bout, tconfig/i960-coff: These are identical
1978 copies of tconfig/i960, added for global configuration
1979 compatability. All i960 versions can read both coff and b.out.
1981 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
1982 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
1985 * TODO: Think of more things to do.
1987 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
1989 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
1990 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
1991 64-bit float conversion.
1993 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
1994 equivalent to sun?os4 so global config works.
1996 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
1998 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2000 * main.c: Only declare linesize once; declare pagesize not at
2001 all, since it is never used.
2002 (main): Clear newly allocated line before it is used.
2004 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2006 Further stabilization for the Intel 960.
2008 * Makefile.dist: Parameterize the location of the "include"
2009 and "bfd" directories, as well as "getopt". Add symfile.c.
2010 Link in both dbxread and coffread. Fix up "make depend" to
2011 rewack the locations of include, bfd, and getopt in its output.
2013 * README: Document moving include files, improve some of
2016 * coffread.c: Move common code out to symfile.c. Change
2017 symbol_file_command style interface to use new *_symfile_init
2018 and *_symfile_read interface under BFD. Use BFD internal
2019 info to locate line table, symbols, etc.
2021 * core.c (core_fetch_registers): Rename to get_core_registers
2022 to avoid confusion with fetch_core_registers.
2023 (register_addr): Move to coredep.c, which is already machine
2024 dependent. This leaves core.c pretty clean of dependencies.
2026 * coredep.c (register_addr): Accept this routine from core.c.
2028 * dbxread.c: Move common code (with coffread.c, etc) into new
2029 symfile.c. Each psymtab now contains a pointer to the
2030 format-dependent function that knows how to read it in. Make
2032 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2033 (process_one_symbol): Add code to complain about a "compiler bug
2034 we muzzle here", if we actually see it.
2036 * eval.c (evaluate_subexp): Insert missing "break" statements
2037 in code that determines whether a variable is an lvalue in
2038 memory, register, or whatever. I detected this via a compiler
2039 bug in which it *almost* mashed out the whole switch statement.
2041 * gdb-int.texinfo: Add minor sections on configuring gdb for
2042 release, and about the README file.
2044 * infcmd.c (registers_info): Fix formatting somewhat. Still
2045 not as pretty as before, but it handles byte swapping.
2047 * remote-nindy.c: If data cache routines are interrupted while
2048 waiting for the remote end, be sure that any uninitialized cache
2049 blocks are on the free list, not on the valid list!
2051 * symfile.h: Flesh out this header file with all the various
2052 routines and variables that have been merged in from dbxread.c
2053 coffread.c, and symtab.c to symfile.c.
2055 * symfile.c: New file, containing code common to dbxread.c,
2056 coffread.c, and some code from symtab.c. All generic code for
2057 reading symbol files should be in here now.
2058 (unrecord_misc_function): Remove unused function.
2060 * symtab.h: Remove file-reading things to symfile.h.
2062 * symtab.c: Remove file-reading things to symfile.c.
2064 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2065 to decode i960 fault types.
2067 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2068 target.c: Change type of the "resume" function from int to void,
2069 since its result was never used.
2071 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2073 * main.c: Replace "stupid" with "caution"; you now "set caution
2076 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2078 * infcmd.c (do_registers_info): Call val_print to deal with the
2079 byte order of the registers being printed. FIXME, this makes
2080 the formatting of the output uglier.
2082 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2083 defined, call it for signals the debugger doesn't itself use.
2084 The i960 uses this for more detailed fault information.
2086 * remote.c (remote_open): If arg is null, print help rather than
2089 * sparc-xdep.c (register_valid): Avoid declaring size, since
2090 various modules will think of various sizes depending on the
2091 architecture of their tm-file. FIXME, we need protection against
2092 actually entering one of those modules, which would clobber
2093 storage if not for the target architecture compiled into gdb.
2095 * stack.c (up_command, down_command): Always print the frame
2097 (up_silently_command, down_silently_command): New commands
2100 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2102 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2103 more parameters than it used to.
2105 * findvar.c (registers): Increase slop to 256 bytes, which should
2106 protect us against even most RISC machines with large register
2108 (locate_var_value): Move declaration inside related ifdef.
2110 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2111 throughout, to avoid throwing away buffered input from the board.
2112 (nindy_wait): Supply_register takes addr_of_value, not value.
2113 (i960_print_fault): Renamed from i80960_fault.
2114 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2115 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2117 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2118 we can set the PC in the call to proceed(). Unpush nindy_ops
2119 before pushing it on top, to avoid message to user. Eliminate
2120 commentary from Unix machines that just misleads here.
2121 (reset_command): Fix error message to suggest target command.
2123 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2125 Release 3.92.5 as frozen.
2127 Stabilize the merged release...with help from lint, Saber C,
2130 Everywhere: Add include files needed to declare return types
2131 of functions called.
2133 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2135 * breakpoint.h: Add undeclared breakpoint functions, and some
2136 functions for display handling since I couldn't think of a better
2139 * breakpoint.c (insert_breakpoints): Make code for disabling
2140 shared library bkpts more likely to work. It's used when we
2141 rerun a program and stop before the shared library has been
2143 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2144 cast from pointer, so it squeezes through catch_errors.
2145 (bpstat_stop_status): Fix logic broken some time ago. We now
2146 always create a bpstat if the stop address matches a breakpoint,
2147 even if we don't stop there -- just like the old code used to do
2148 before I got my fingers into it (sigh).
2149 (breakpoint_1): Print "ignore count" after "stop only if"
2150 condition, since that's how it actually works.
2151 (mention): Handle watchpoints as well as breakpoints.
2152 (watch_command): use set_raw_breakpoint and mention to do most
2153 of the work (and initialize all the fields!). Only pass one
2154 arg to parse_c_expression, since that's all it takes.
2156 * command.c (not_just_help_class_command): Rename arg to args
2157 since we ignore "unused argument" warnings on vars named "args".
2158 inflow.c (child_terminal_info): ditto.
2159 infptrace.c (kill_inferior): ditto
2160 main.c (catch_errors, version_info, quit_command, pwd_command,
2161 source_command, dump_me_command, editing_info,
2162 set_history_size_command, set_history, show_history,
2164 stack.c (locals_info): ditto
2165 target.c (target_files_info): ditto
2166 valprint.c (set_input_radix, set_output_radix): ditto
2168 * core.c: Remove old variables for handling core and exec file
2169 sections (data_start, data_end, stack_start, stack_end,
2170 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2171 text_end, exec_data_start, exec_data_end, text_offset,
2172 exec_data_offset, data_offset, stack_offset). They're
2173 superseded the more general build_section_table and
2175 (get_exec_file): Mention the `file' command.
2176 (read_memory_check): Rename to memory_error, and only call it
2177 in the case of an actual error.
2178 (read_memory, write_memory): call memory_error.
2179 (core_fetch_registers): Register section name is ".reg".
2181 coredep.c: Remove a bunch of crud now that all this file does
2182 is pull the registers out of a core file.
2183 (fetch_core_registers): Rewrite to actually work, I hope.
2185 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2186 Replace index() with strchr(). Remove all the pre-BFD macro
2187 definitions for accessing the symbol file.
2188 (struct dbx_symfile_info): Encapsulate the information that
2189 dbx_symfile_init needs to pass to dbx_symfile_read in this
2192 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2193 dbx_symfile_discard): Rearrange symbol file reading to divide
2194 the format-specific part from the format-independent part,
2195 leaving the format-independent part such as file name expansion
2196 and opening in symtab.c. This replaces
2197 partial_symbol_file_open and partial_symbol_file_read.
2198 Symbol_file_read, add_file, add_file_target_command,
2199 add_file_addr_command move to symtab.c. Pass an explicit
2200 "mainline" flag for when reading the main symbol table, rather
2201 than relying on the offset address to be zero or nonzero.
2203 (dbx_symfile_read): Don't allow void *'s to be printed as
2205 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2206 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2207 macro" debug version really work.
2208 (read_dbx_symtab): Remove unref'd parameter inclink.
2209 Avoid swapping N_SLINE symbols, for speed.
2210 Merge N_TEXT!N_EXT case with the other external symbol
2211 definitions' case. Add comments.
2212 (start_psymtab): Allocate the symfile name in the psymtab on
2213 the psymbol_obstack, rather than using the caller's storage.
2214 (end_psymtab): Only allocate a dependencies list if there are
2216 (psymtab_to_symtab_2): Use BFD when reopening file to read
2217 its symbols for real.
2218 (read_struct_type): Add FIXME comments where it needs work
2220 (read_huge_number): Add FIXME about overflows.
2221 (read_range_type): Add FIXME about comparing a long to 1<<32.
2223 * coffread.c: Minor changes to move things closer to the new
2224 regime with symtab.c and dbxread.c Major work is still needed
2227 * exec.c (exec_file_command): Remove old variables (see core.c
2229 (xfer_memory): If memory transfer is right at the end of a
2230 section, don't lose.
2232 * findvar.c (get_saved_register): If value is in a real
2233 register, LVAL is lval_register, not lval_memory.
2235 frame.h: Declare print_sel_frame and record_selected_frame.
2237 gdb-int.texinfo: New file, for GDB internals documentation.
2238 Very simple, unformatted doc of cleanups is there for now.
2240 gdbcore.h: Remove obsolete variables that described a.out
2241 section addresses and offsets. (See core.c above.)
2242 Declare fetch_core_registers and registers_fetched.
2244 getopt.c: Declare char *alloca(); even on SPARC.
2246 infcmd.c (run_command): Call target_kill rather than
2248 (step_command, next_command, stepi_command, nexti_command):
2249 Declare from_tty parameter even though we don't use it.
2250 (run_stack_dummy): argument BUFFER is a char array, not
2251 a pointer to REGISTER_TYPE.
2252 (finish_command): using_struct_return needed a value *,
2253 not a struct symbol *.
2255 * infptrace.c (child_xfer_memory): To avoid dependency on
2256 where sections are in memory, try PT_WRITE_D and if that fails,
2257 try PT_WRITE_I. Most Unixes don't care which you use.
2259 * infrun.c (step_resume_break_shadow): Change to array to
2260 match other breakpoint shadow storage.
2261 (clear_proceed_status): Pass address of bpstat to
2262 bpstat_clear, not the bpstat itself.
2263 (child_create_inferior): FIXME comment about if the child
2265 (start_inferior): Remove old function.
2266 (child_open): Use target_kill rather than kill_inferior.
2267 (wait_for_inferior): Ditto.
2268 (insert_step_breakpoint, remote_step_breakpoint): Use
2269 new step_resume_break_shadow.
2271 * inftarg.c (child_wait): If all child processes die,
2272 pretend that the one being waited for exited with signal 42.
2274 * main.c (command_line_input): When scanning for comments,
2275 don't coredump on unclosed quotes.
2276 (quit_command): Use target_kill rther than kill_inferior.
2277 (_initialize_main): Rename class_user from "user" to
2280 * printcmd.c (print_command_1): Initialize "fmt" if no format
2281 is specified by the user.
2282 (print_frame_args): Only add to args_printed if we are
2283 actually fetching args from the stack (avoiding undefined
2285 (_initialize_printcmd): Remove bogus \{ from string.
2287 * remote-eb.c (eb_open): Avoid coredump on no argument.
2289 * remote-nindy.c: Bring out of Intel environment into new
2290 target environment. Remove all conditional compilation on
2291 I80960. Massive hacking throughout.
2292 (nindy_xfer_inferior_memory): New routine stolen from
2294 (nindy_create_inferior): New routine pieced together, probably
2295 not quite working yet.
2296 (nindy_ops): New target_ops struct for nindy.
2298 * remote-vx.c: Use write_memory rather than target_write_memory
2299 to get error checking.
2300 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2302 (vx_create_inferior): Use target_terminal_ours...
2304 * signame.c (_initialize_signame): Always initialize, since
2305 we need the table for things other than psignal.
2307 * solib.c (solib_add): Use symbol_file_add, not add_file.
2308 (solib_address): Return boolean result rather than struct
2309 pointer which nobody else knows the type of.
2311 * sparc-tdep.c, valops.c: Use write_memory rather than
2312 target_write_memory, to get error checking.
2314 * stack.c (locals_info, catch_info, args_info,
2315 get_selected_block, frame_command, up_command): Use
2316 target_has_stack, rather than have_inferior_p or
2319 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2321 * symfile.h: New file, defining the interface between the
2322 generic and object-file-specific symbol reading code.
2324 * symtab.c: Move generic symbol-reading interface to symtab.c,
2325 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2326 table to map BFD targets to symbol-reading modules in GDB.
2327 Change index to strchr.
2328 (lookup_struct_elt_type): Use error() rather than hand-made
2329 simulations thereof.
2330 (lookup_partial_symbol): Speedup slightly when length == 0.
2331 (symbol_file_add): New function.
2332 (symbol_file_command): Call it.
2333 (symfile_open, symfile_init): New function.
2334 (add_file_target_command, add_file_addr_command): moved from
2337 * target.c (target_command): use target_kill.
2339 * target.h (target_files_info): Don't declare, never called
2342 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2343 files to determine stack end address.
2345 * valarith.c (value_x_binop, value_x_unop): Change error message
2346 to be more useful. Pass proper argument to value_struct_elt.
2348 * valops.c (value_assign): FIXME comment that long long
2349 bitfields will break here.
2351 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2352 Update `make saber_gdb' to work better.
2354 * TODO: A woman's work is never done.
2356 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2357 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2358 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2359 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2360 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2361 valops.c, valprint.c, exec.c: Lint.
2364 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2366 Continuing Intel 960 port merge of GDB.
2368 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2369 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2370 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2371 Wack over "make depend" so it handles files in subdirectories
2372 vx-share, nindy-share, bfd, and in the current directory.
2374 * blockframe.c (get_prev_frame_info): Remove fatal error
2375 if stack not defined.
2377 * core.c (core_open, core_detach): New functions that handle
2378 the old "core-file" command as "target core" and "detach" instead.
2379 (core_file_command): Call them.
2380 (core_xfer_memory): Use common routine xfer_memory.
2382 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2383 dbxread now uses bfd for everything but symbol reading itself.
2384 BFD internals are used to drag out the relevant file offsets.
2385 (partial_symbol_file_open): Change args all around for BFD.
2387 * symtab.c: Rename "value" to "val" everywhere, so we can
2389 (symbol_file_command): New command, moved from dbxread.c
2390 and coffread.c. It uses BFD to read the file, then vectors
2391 based on its type, to dbx or coff symbol readers.
2392 * symtab.h: Extern a few vars for symbol_file_command.
2394 * target.h: Breakpoint takes a char * save area, not a char **.
2396 * valprint.c (val_print): When unpacking bitfields, offset
2397 the address in gdb of the value, if it is declared with a shorter
2398 type. Remove the last "runtime kludge test" of host byte order.
2400 * utils.c: Remove old my_bfd_read routine.
2402 * stack.c (frame_info): Use target_has_stack. Print program counter
2403 register's actual name rather than "pc", since it's called the
2404 "ip" (instruction pointer) on the i960 (sigh).
2406 * target.c (target_command): Add command for selecting a target
2407 type and calling its open routine. This is used for initiating
2408 communication with a particular target, in a generic way.
2410 * tm-i960.h: Update for modern gdb. Remove semicolons from
2411 various macros. Handle reading struct return convention, and
2412 error-out attempts to return structs with the "return" command.
2413 Be sure gdb doesn't think we know how to call functions in the
2416 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2417 to i960_xxx in lower case.
2418 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2419 not being defined yet.
2421 * remote.c (remote_open): Call start_remote to initialize
2422 wait_for_inferior during open.
2423 (remote_xfer_inferior_memory): Return length written rather
2426 * remote-vx.c (target_command -> vx_open): Use new generic
2428 * remote-eb.c, inftarg.c, exec.c: ditto.
2430 * infrun.c: Fix comments.
2431 (attach_program -> child_open): Use new generic target command.
2432 (wait_for_inferior): Clear saved register values before target_wait,
2433 so target_wait can set some of them if convenient.
2435 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2436 Return success indicator, not void.
2437 (child_xfer_memory): Avoid fetching initial word if we'll
2438 overwrite it anyway.
2440 * infcmd.c (attach_command): Use new generic target open routine.
2441 (_initialize_infcmd): Update doc on attach and detach commands.
2442 (do_registers_info): Merge in a byte-order problem as a FIXME
2445 * findvar.c (find_saved_register): Avoid problem in current frame.
2446 (read_relative_register): Ditto.
2447 (write_register): Convert byte order on the way out.
2449 * exec.c (file_command): Add.
2450 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
2451 (xfer_memory): Common function between core_xfer_memory and
2453 (exec_xfer_memory): Use it.
2455 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
2457 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
2458 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
2459 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
2461 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
2463 Merge Intel 960 port of gdb, continuing...
2465 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
2466 symbol_file_command): Pass from_tty arg to hush 'em up.
2468 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
2469 Add magic numbers for 960 COFF format.
2471 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
2473 Merge Intel 960 port of gdb, from Intel "1.2" release.

2486 Tue May 29 12:54:49 PDT 1990
2487 Added variable baud rate (-b switch).
2488 Source code reorganization.
2490 Thu Apr 26 11:09:55 PDT 1990

2494 Fri Apr 20 13:47:15 PDT 1990
2497 Thu Apr 19 09:54:28 PDT 1990
2498 Add 'reset' command.
2500 Wed Apr 18 09:48:07 PDT 1990
2501 After opening remote tty, wait for 1 second to go by without input
2502 from it before trying to talk to NINDY (fixes problems with the
2503 Heurikon HK80/V960E).
2505 Mon Apr 4 16:33:05 PDT 1990
2506 Some output was not being suppressed in 'batch' mode.
2508 Thu Mar 22 15:31:11 PST 1990
2509 Ask user if old symbol table should be deleted when new file is
2512 Allow user to run a program downloaded before gdb960 was brought up.

2523 Correct bug that made it impossible to get source line numbers for
2524 code loaded at addresses higher than 0x7fffffff.
2526 Wed Jan 10 12:43:22 PST 1990
2527 Open remote tty for exclusive use.
2529 Fri Jan 5 12:14:42 PST 1990

2539 Mon Oct 2 15:56:31 PDT 1989
2541 Added 960CA disassembly support.
2543 To simplify maintenance:
2544 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
2546 - eliminated opcode.h: incorporates tables into i960-pinsn.c
2547 - moved 960-specific routines from i960-pinsn.c to i960-md.c
2548 - made disassembly interface identical to that in gdmp960.
2552 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
2554 * target.h: Allow targets to stack. Add target_has_memory,
2555 _registers, etc. Restructure memory access and "info files"
2556 to walk the target stack.
2557 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
2558 target.c: Change tables to match target.h.
2559 * inflow.c (child_mourn_inferior): pop child_ops.
2560 (generic_mourn_inferior): Use new has_stack flag.
2561 * infptrace.c (child_xfer_memory): New memory regime.
2562 * inftarg.c (child_files_info): New "info files" regime.
2563 * remote-eb.c: New memory regime, new info files.
2564 * remote-vx.c: New memory regime, new info files. Now use
2565 separate targets for VxWorks attachment to machine, and
2566 actually running a process under VxWorks, since one has
2567 stack & execution & regs and the other doesn't.
2568 * remote.c: New memory regime, new info files.
2569 * sparc-xdep.c (fetch_core-registers): New memory regime.
2570 * target.c: New routines and support for stacked targets,
2571 new memory regime, new info files regime.
2574 Generalize section handling for an arbitrary number of sections,
2575 including use of the new BFD (binary file) library.
2576 * gdbcore.h: Add struct section_table.
2577 * exec.c (build_section_table): Iterate all sections and
2578 record what gdb needs to know about them.
2579 (exec_command): Use it.
2580 (exec_xfer_memory): Use the table.
2581 (exec_files_info): Print the table.
2582 * core.c (core_file_command, core_xfer_memory, core_files_info):
2584 * source.c (find_source_lines): Use bfd_get_mtime.
2585 * dbxread.c: Quick changes to make it compile with new BFD.
2586 * utils.c (error): Avoid using bfd_error in generic routines.
2588 * core.c (core_fetch_registers): Get from the ".regs" section of
2590 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
2592 * inferior.h (attach_flag): Export.
2593 * infcmd.c (run_command): use new target_create_inferior.
2594 * infrun.c (child_create_inferior): Don't return result.
2595 * Makefile.dist (VERSION): 3.91.4.
2597 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
2599 * breakpoint.c (bpstat_num): Handle breakpoints which have
2600 since been deleted, such as temporary breakpoints.
2601 infcmd.c (program_info): ditto.
2603 * core.c (core_file_command): Display the frame where the core
2608 * remote-vx.c (target_command): Merge in target command from
2609 targ-vx.c. A few other cleanups.
2611 * TODO, Projects: Lots more stuff to do...
2613 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
2615 Massive changes to wall off the remote-debugging interface
2616 behind a function vector. The port to handle VxWorks targets
2617 is also part of this.
2619 All files: Replace references to renamed functions,
2620 remove references to remote_debugging, remove references to
2621 have_include_file, have_core_file in favor of target_has_stack,
2622 target_has_memory, etc.
2624 * Modularize the breakpoint interface.
2625 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
2626 a breakpoint instruction.
2627 breakpoint.c: struct breakpoint's shadow_contents now sized as
2629 (insert_breakpoints): Vector to target to install breakpoints.
2630 (remove_breakpoints): Vector to target here too.
2631 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
2632 sparc-tdep.c (single_step): Use new breakpoint interface for
2633 the single-step breakpoints.
2634 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
2635 New file, contains routines to insert and remove breakpoints by
2636 reading out the old contents and later replacing them. This is
2637 how ptrace breakpoints work, and many remote systems as well.
2639 * tm-vxworks68.h: New config file, overrides a few things for
2640 Wind River's preferences.
2642 * target.h: New file, for transfer vector used to talk to the
2643 inferior (child, attached, core, exec, remote, etc). All accesses
2644 to the thing being debugged should come through these vectors.
2645 target.c: New file, routines to handle transfer vector.
2646 (various files): Add transfer vectors XXX_ops for the various
2647 targets and pseudo-targets (core files, etc) we support.
2649 * breakpoint.c (bpstat_stop_status): Further explorations of
2650 watchpoints and why things don't work all the time.
2651 (bpstat_alloc): New fn to allocate a bpstat and chain it.
2653 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
2654 the local gdbinit if it doesn't already have it.
2656 * core.c (core_ops): add and install.
2657 Allow core debugging without exec file.
2659 * dbxread.c (free_and_init_header_files): Merge two fns.
2660 (end_symtab): Free named symbol table when a new version comes in.
2661 (read_dbx_symtab): Relocate all kinds of symbols with base
2662 address. First step toward handling different text, data, bss
2664 (add_file_addr_command): Renamed add_file_command.
2665 (add_file_command): Vector to remote handler.
2666 Add "load" as an alias for "add-file" command.
2668 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
2669 non-returning functions.
2671 * exec.c: Add exec_ops, and push it as a target when an exec
2674 * infcmd.c (run_command): Pass executable file name and arg list
2675 separately when starting an inferior. Permit "run" when no exec
2676 file is specified, for VxWorks.
2677 (detach_command): Move to child_detach in inftarg.c.
2679 * inftarg.c: New file. Unix-child-specific routines, and the
2680 child_ops structure.
2682 * inferior.h (registers): Export "registers" as the way for
2683 target dependent register handlers to find gdb's local copy of
2684 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
2685 since it is now used by places that want wait_for_inferior to
2686 handle the grunge but want to see every trap from the inferior.
2688 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
2689 Eliminate remote_debugging hooks in terminal handling.
2691 * infrun.c: Replace start_inferior with child_create_inferior.
2692 Move all the hair of Unix shells and ptrace idiosyncracies into
2693 child_create_inferior, so remote handlers don't have to deal.
2694 Remove running_in_shell. Rename stop_after_attach to
2695 stop_soon_quietly, and use it in a few other places where we want
2696 to just call wait_for_inferior and get control back on the first
2697 trap. trap_expected now never takes a value > 1.
2698 (init_wait_for_inferior): Initialize static vars when a new
2701 main.c (gdbinit): Add new hook for .gdbinit file name, let
2702 it be overridden by config files as GDBINIT_FILENAME.
2703 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
2704 Both of these are used for VxWorks gdb.
2706 mcheck.c: rename include file "gmalloc.c" to avoid problems
2707 with system include file "malloc.c".
2709 param-no-tm.h: New include file, same as param.h but does not
2710 include the default "tm.h" file. This is used in files where
2711 the target is known, e.g. remote-eb.c or sparc-xdep.c.
2713 param.h: Now just a shell that includes tm.h and param-no-tm.h.
2715 remote-vx.c: New file, VxWorks remote debugging support. Uses
2716 RPC routines that are shared with the target system, in directory
2719 remote.c: Vectorize remote interface.
2721 source.c: Globalize source_path, and make an alias "l" for "list"
2722 since we now have the "load" command.
2724 sparc-xdep.c: Use new param-no-tm.h.
2726 symmisc.c (free_named_symtab): Add new function from Wind River.
2727 However, ifdef it out for now while we think about what it should
2730 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
2732 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
2733 non-Unix-children handle this with their own code in the target
2736 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
2737 source and target lists. Add vx-share to default list of include
2738 directories. Add new files to src and target lists: mem-break,
2739 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
2740 ${srcdir} versions of munch and createtags are used.
2742 * valops.c (find_function_addr): Split out of call_function.
2743 (call_function_by_hand): Rename call_function; this function
2744 calls functions in the target by laboriously patching the target
2745 word-by-word with the right stack, args, regs, etc.
2748 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
2750 Handle AMD 29000 a bit better.
2752 * remote-eb.c (readchar): Mask received char log to make it readable.
2753 (remote_start): Pass arguments down to executing program.
2754 Make startaddr unsigned.
2755 infrun.c (start_inferior): Accept args, pass them to
2757 infcmd.c (run_command): Pass args down to start_inferior.
2759 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
2760 the target object file format.
2761 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
2763 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
2764 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
2766 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
2768 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
2769 * TODO: We did a few things, we have more to do though.

2772 * inflow.c (inferior_died): Clear deferred stores.
2774 * Debug problems with dummy frames and calls to the inferior.
2775 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
2776 * sparc-tdep.c (do_restore_insn): Simplify.
2777 (sparc_frame_find_saved_regs): Simplify and fix what we find.
2778 (sparc_push_dummy_frame): Simplify and fix what we push.
2779 (sparc_pop_frame): Slightly more hair here, deciding whether
2780 we are restoring a saved PC or returning to a return address in %i7.
2781 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
2783 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
2784 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
2785 * obstack.h (chunkfun): ditto.
2786 * defs.h (xmalloc, xrealloc): ditto
2788 * utils.c (quit): Grab the terminal from the child if necessary.
2790 * inflow.c (term_status_command): Rename to term_info, change
2793 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
2794 (is_delayed_branch): Speed up.
2795 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
2796 Still missing some float ops, and needs testing.
2798 * Support for input and output radixes other than base 10
2799 * defs.h (input_radix, output_radix): Declare.
2800 * expread.y (yyparse, parse_number): Handle changes of input
2801 radix, and ambiguous names-or-numbers in radixes >10.
2802 * printcmd.c (print_scalar_formatted): Print formatted hex
2803 numbers in varying column widths.
2804 * valprint.c (val_print): Use output_format to print scalar ints.
2805 (set_input_radix, set_output_radix, set_radix): Create.
2806 (set_output_radix): Set output_format from output_radix.
2807 (_initialize_valprint): add `set radix' but leave the others off.
2809 * main.c (execute_command): Let stupid questions be turned off.
2810 (_initialize_main): Handle "set stupidity", etc.
2812 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
2813 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
2815 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
2817 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
2818 bfd stuff is still screwed up, but with some manual work, it
2821 * breakpoint.c (bpstat_do_actions): Start over if a command
2822 proceeds the inferior, since the inferior will have stopped and
2823 will need to have its new stop-actions taken care of.
2825 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
2826 compiler fits, simplify it.
2828 * gdb.texinfo (directory command): Doc new dir command.
2829 source.c (directory_command): "dir" now puts things on the front
2830 of the path, moves dups up front, and handles multiple names
2831 on the command line, inserting each one in order. It also
2832 blows away cached line and full_filename info.
2834 * stack.c (backtrace_command): Skip "more stack frames follow"
2837 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
2838 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
2839 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
2840 The only odd one was Gould NP1, which had defined vprintf to
2843 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
2844 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
2845 variable, inspect_it.
2846 valprint.c (print_string, val_print): Use the global inspect_it
2847 to indicate whether to print in Epoch style or normal style.
2849 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
2851 * printcmd.c (call_command): add an alias for the "print" command
2852 which runs expressions and doesn't print the result if void.
2853 (print_command_1): implement it.
2855 * command.c: Remove #if 0'd code. Initialize all the fields
2856 in add_cmd (). Rename do_nothing_command to
2857 not_just_help_class_command, and make it externally visible.
2858 command.h: add user_commands to struct.
2859 * main.c (define_command): Don't overload c->function with a char
2860 string as well as a function pointer.
2862 * eval.c (evaluate_subexp): Reinstall tiemann changes to
2863 calling convention of value_struct_elt () that got dropped in
2866 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
2867 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
2869 * tm-sparc.h (POP_FRAME): replace some constants with defines.
2871 * sparc-xdep.c (store_inferior_registers): defer stores to regs
2872 until a good time (e.g. when we are about to run the child),
2873 saving ptrace calls.
2874 * infrun.c (proceed): handle DO_DEFERRED_STORES.
2875 * tm-sparc.h: define DO_DEFERRED_STORES.
2877 * sparc-xdep.c (store_inferior_registers): when storing float
2878 registers, don't store stack regs too. When storing the SP,
2879 however, DO store the stack regs too. This fixes a bug in which
2880 the dummy frame is not recognized when a call_function finishes,
2881 because its frame pointer (in the stack regs) was never
2883 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
2884 even though we don't know how to read them from an inferior.
2885 valops.c (call_function): Comment about storing SP.
2887 * infrun.c (save_inferior_status): Save away the original bpstat
2888 chain so it can be restored later. Install the copied version for
2889 use by whoever saved the status. It will be blow away by
2890 restore_inferior_status, and the original chain restored. This is
2891 important for people who have pointers into the original.
2893 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
2894 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
2895 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
2898 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
2900 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
2901 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
2902 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
2904 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
2906 * Merge Mike Tiemann's multiple inheritance changes from Sun.
2907 Store the baseclasses in a type struct starting from array element
2908 0 rather than from the unusual array element 1.
2910 dbxread.c: the above.
2911 (virtual_context): Add
2912 Read new debug information about which virtual function table
2913 a virtual function is from, and store it in fn_field.fcontext.
2915 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
2916 TYPE_FN_FIELD_STATIC_P.
2918 symtab.c: the above.
2919 valops.c: the above. Handle pointer casts of object *'s.
2920 (search_struct_method): Add.
2921 (value_struct_elt): First arg is now a pointer to a value, and is
2924 valprint.c: the above.
2925 values.c (value_virtual_fn_field): Add type arg. Handle
2926 offsetting to the proper object when calling virtual fns.
2928 (baseclass_addr): Add valuep arg.
2930 * README: Document the current state of BFD config (missing).
2931 * TODO, ChangeLog, Makefile.dist: Roll version.
2932 * WHATS.NEW: Add summary of changes since 3.5.
2934 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
2936 * dbxread.c (read_struct_type): Clear bit vectors whenever
2938 symtab.c (B_CLRALL): define.
2940 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
2941 using == rather than =. Huh... This fixes the dreaded problem
2942 wherein builtin_type_int becomes TYPE_CODE_FLT.
2944 * core.c (info_files): Show the inferior pid.
2946 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
2947 already knows how to look in the source directory.
2949 * Remove psymtab hair from many places. Remove duplicated code
2950 for searching symbol tables. Hide psymtabs from most places.
2951 Make it fast to get from a psymtab to its symtab.
2953 blockframe.c (blockvector_for_pc): Remove psymtab hair.
2954 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2955 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2956 dbxread.c: export psymtab_to_symtab, make it work if called N times.
2957 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
2958 new symtab completely. New psymtabs get symtab pointer
2959 initialized to zero. Remove MI warning printf.
2960 symtab.h: Comments. Add psymtab to symtab pointer.
2961 (PSYMTAB_TO_SYMTAB): New macro.
2962 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
2963 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
2965 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
2967 (print_frame_info): Avoid special-casing symbols that have not yet
2970 * source.c (open_source_file): Quick path if we have already
2971 located the source file by its full name.
2973 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
2974 find_pc_psymtab. When a name is found in the misc function
2975 vector, search the symbol table for its mangled name, not the
2976 name that the user typed.
2978 * bfd.h: Fix missing comment terminators, make #endifs match.
2980 * valarith.c (value_less): Handle unsigned int comparisons.
2981 Add FIXME about pointer compares, which assume host and target
2982 pointers are the same.
2984 * command.c (do_nothing_command): lint
2985 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
2986 fix comments on debug symbol format for visibility. Actually set
2987 visibility of symbols.
2988 main.c (echo_command): lint; use <readline/history.h>.
2989 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
2990 obstack.h (_obstack_blank): Rearrange pointer math to avoid
2991 pointing past end of allocated memory; saber complains.
2992 obstack.h: Declare the external functions that we use.
2993 valarith.h: use <string.h>
2994 solib.c (solib_add): lint.
2996 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
2998 * main.c (initialize_main): Default info_verbose to off, now that
2999 symbol reading is fast.
3000 (quit_command): Avoid clobbering exec_bfd while quitting.
3002 * Initial BFD (binary file diddling library) merger:
3003 coffread.c: Change AOUTHDR to struct exe_hdr.
3005 core.c: initialize initialized data at compile time.
3006 (core_file_command): Move from coredep.c, convert to bfd.
3007 (xfer_core_file): Convert to bfd.
3008 exec.c (exec_file_command): use bfd routines.
3010 mips-tdep.c: Remove exec_file_command and friends.
3013 * coredep.c: (fetch_core_registers) Convert core_file_command to
3014 fetch_core_registers.
3015 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3017 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3018 (my_bfd_read): More bogosity, which I don't think we call.
3019 (program_name): Remove this atrocity asap!
3021 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3024 values.c: allocate_repeat_value was not clearing the
3025 optimized_out field.
3026 (value_static_field): minor stylistic fix (wrong macro was used).
3027 valops.c (value_struct_elt_for_address): didn't work for C++
3030 * signame.c (_initialize_signame): Initialize signal names once.
3032 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3033 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3034 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3036 * remote-eb.c: Support user-settable baud rates on the serial port.
3038 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3040 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3042 * tconfig/sun3os4: Remove warning about native assembler,
3043 since it also occurs in the xconfig file.
3045 * findvar.c (registers): Allocate some slop after `registers'
3046 to prevent stray accesses from trashing the next variable.
3048 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3049 on the sun-3, by changing the #ifdef from `sun3' (which is not
3050 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3051 vars, which happened to follow `registers' in the executable.
3053 * readline/history.c (history_search): Heed gcc-2's advice
3054 and parenthesize && inside ||).
3056 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3057 tm-29k.c: Insert FSF copyright headers.
3059 * remote-eb.c: Better comments.
3061 * Makefile.dist: Update to 3.91.6.
3062 * TODO: note PREPARE_TO_STORE problem.
3064 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3066 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3068 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3070 * infrun.c (wait_for_inferior, at end): Don't set up
3071 prev_* if the inferior no longer exists.
3073 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3074 CANNOT_EXECUTE_STACK.
3075 valops.c (call_function): Use it.
3077 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3079 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3080 infrun.c (wait_for_inferior, 2 places): Use it.
3082 * values.c (value_being_returned): Only use
3083 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3085 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3086 right thing for remote-eb.c.
3088 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3089 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3091 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3092 (FRAME_FIND_SAVED_REGS).
3094 * findvar.c ({fetch,store}_registers): Check for
3095 REMOTE_{FETCH_STORE}_REGISTER macro.
3097 * findvar.c (get_saved_register): Add argument lval and
3098 change meaning of argument addr.
3099 findvar.c: Change calls to get_saved_register to reflect
3100 new calling convention.
3101 valops.c (value_assign): Use get_saved_register instead of
3102 find_saved_register.
3104 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3106 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3107 an (uninitialized) pointer to one. Use "&" when passing it
3110 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3112 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3115 * coffread.c (symbol_file_command): Put semicolon after
3117 Put safe_to_init_tdesc_context in #if defined (TDESC).
3118 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3119 coffread.c: #include <sys/stat.h>.
3120 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3121 Add missing ')' in check for "lc%" and friends. Remove
3123 Declare read_one_sym() at top of file.
3124 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3125 MC68WRMAGIC can have the same value without causing a duplicate
3128 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3130 * Allow a Makefile to be built without building the
3131 tm and xm file links that screw up builds in subdirectories.
3132 This is done with `config.gdb none', then you can do things
3133 like `make gdb.tar.Z'.
3134 * tconfig/none: Config file for no target system
3135 * xconfig/none: Config file for no host system
3136 * config.gdb: If no TM or XM files are called out by the
3137 host or target file, don't make links for them.
3139 * cplus-dem.c: Add documentation.
3141 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3142 simple error, so the user's gdb doesn't crash due to some object
3143 file problem (e.g. somebody is rebuilding the file out from under
3146 * printcmd.c (print_address_symbolic): demangle the symbol.
3148 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3149 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3150 (alldeps.mak): sort and uniq all results from this; duplicates
3151 hose gdb.tar.Z link building. Remove RCS files from
3152 tconfig and xconfig. Add config files for sun386. Add
3153 a few odd files to OTHERS and HFILES.
3155 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3157 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3158 Roll version number to 3.91.5. Make lint work in bindir.
3160 * README: Document cross-debugging and new file structure.
3162 * blockframe.c: Lint. Include "value.h" to declare read_register.
3163 (find_pc_partial_function): remove duplicate line.
3165 * command.h: Lint. Declare error_no_arg and dont_repeat.
3167 * tm-news.h: Remove inadvertently duplicated stuff.
3169 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3170 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3172 * config.gdb: Allow `config.gdb host target' form. Clean
3173 up previous change that printed bogus messages when you just said
3176 * core.c: #include "command.h" for lint.
3179 * main.c: Remove some casts of enums. Lint.
3186 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3188 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3189 read it from memory. This will allow us to save ptrace calls
3190 eventually. Changed caller single_step too.
3192 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3193 that we aren't going to use, saving many ptrace calls, especially
3194 when watchpointing or single stepping. Use some #define's for
3196 (store_inferior_registers): Ditto.
3197 (core_file_command): Use some #define's for constants.
3199 * tm-sparc.h: Add #define's for some register numbers, so we
3200 can eliminate the use of random constants in sparc-xdep.c.
3202 * stack.c (frame_command, print_frame_info, up_command,
3203 down_command) Remove frame_changed, since it
3204 causes a bug and doesn't seem to do anything useful. In some
3205 places it was used as a flag, in others as a stack level (?).
3207 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3208 default is to use the portable (vprintf) version rather than the
3210 * xm-news.h (MISSING_VPRINTF): Add.
3212 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3214 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3216 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3217 about linking debugged programs -Bstatic in the sun?os4 config
3218 files in tconfig and xconfig subdirectories.
3220 * main.c (main): Remove unreached exit(0) now that we exit
3223 * Create TODO file for online bug list. There are too many
3224 "little" bugs to keep track of on paper.
3226 * Change Projects file to refer to bug-gdb@cygnus.com
3227 rather than kingdon@ai.
3229 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3231 * Makefile.dist (VERSION): 3.91.4 now.
3233 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3234 (condense_misc_bunches): Add sanity check that misc_count is
3235 the same as the number of symbols in the bunch.
3237 * coffread.c: rename init_misc_bunches. Pass an argument
3238 to condense_misc_bunches (a zero).
3240 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3241 every time we are called; don't rely on our caller to do it.
3242 (add_file): Remove call to init_misc_bunches.
3244 * mipsread.c: Only warn, don't error, if unknown symbol types.
3245 This keeps an old gdb from falling on its face if it sees newly
3246 extended symbol info. Rename init_misc_bunches.
3248 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3250 * Merge in changes from Per Bothner for DECstations and other
3251 MIPS stuff. The rest is Bothner speaking:
3253 The next message is a merger of Alessando Forin's mips port with
3254 mine. I've tried to use my good if biased judgment to get
3255 the best of both. It *does* need testing.
3257 Some of the changes are general, *not* mips-specific.
3260 Didn't believe in little-endian bit order.
3261 There are still inconsistencies about whether flags
3262 like BITS_BIG_ENDIAN are integer (#if ...) or
3263 boolean (#ifdef ...). I tried to paper over them.
3265 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3266 Moved some misc_function code that was common to
3267 {dbx,coff,mips}read.c to symtab.c.
3268 In the process, I think I cleaned things up a bit.
3269 At the same time, moved obsavestring and obconcat to symtab.c.
3272 Removed obsolete condense_addl_misc_bunches (use
3273 condense_misc_bunches(1) instead).
3276 Needed to include <sys/dir>, at least on DECstations.
3278 valops.c, mips-tdep.c, tm-mips.h:
3279 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3280 conventions (when STACK_ALIGN is insufficient).
3281 Needed on mips, where doubles need 8-byte alignment,
3282 but ints only need 4.
3285 Removed cruft that was not being used.
3286 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3289 Print $ before register-names (I think that makes things a little
3291 Never print two instructions, even if one delays.
3292 Removed hex-disassemble set_cmd. (This is not mips-specific,
3293 so I think the argument is whether it is generally worthwhile or not.
3294 I'm inclined to think not, given how easy it is to
3295 convert between radixes in gdb.)
3298 This is basically Alessando's code.
3299 It doesn't use obstacks; I changed it to use obstacks
3300 in a few minor places where using malloc causes a
3301 memory leak. (Probably, more places could/should be changed.)
3302 I added record_misc_function where it was missing.
3303 In symbol_file_command and add_file_command, I tried
3304 to make the code consistent with more recent versions.
3305 Minor sylistic changes in parse_procedure.
3306 Make a .gdbinfo. psuedo-symbol point back to the real
3307 procedure symbol (using the isym field).
3310 This is basically from my port, but with a lot of details
3311 and a number of routines merged in from Alessando's version.
3312 I basically used my code "raw" backtrace (use heuristics
3313 from the actual code, rather than symbol table info) - though
3314 the idea is Alessandro's. I feel my code is a little cleaner
3315 here, particularly in being a little more flexible, such as being
3316 able to handle gcc-produced code (which it now can).
3317 It also doesn't do frame caching (which is not useful
3318 more recent gdb versions).
3319 I also used my code for push_/pop_dummy, more or less.
3320 I tried to incorporate AF's code for testing sigtramp
3321 while backtracing; I probably got it wrong.
3322 Added mips_print_register, which tries to scrunch as much
3323 information as possible on a screen...
3324 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3325 under mips-pinsn.c), I don't see anything mips-specific here,
3326 and I don't see it being all that useful anyway.
3329 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3330 Use more register names (rather than hard-cases numbers).
3332 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3334 * Hack up 3.90.11 changes:
3336 * Makefile.dist (depend): parameterize $(GCC).
3337 Add solib.c and solib.o.
3338 (readline): Fix vpath for both absolute or relative SRCDIR.
3340 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3341 Also, let the part I didn't understand at least compile so
3342 I can test the rest. FIXME.
3344 * dbxread.c: Fix thinko using strcmp.
3345 (init_psymbol_list): declare static.
3346 (partial_symbol_file_open): Comment cleanups better, avoid
3347 cleaning up the string table since the caller will do that.
3348 Move the stat for mod time into symbol_file_command, temporarily.
3349 (There should be a mod time for each symbol file, eventually,
3350 to control its rereading. FIXME.)
3352 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3353 SunOS, which gives error for shared libs otherwise. (From
3354 Schaefer, probably FIXME needs work for portability.)
3356 * solib.c: Move #include "param.h" to work.
3357 Lowercase all the Uppercase Letters In the Messages.
3358 (find_solib): Clean up inferior_so_name for debug printouts.
3359 Allow no argument, to mean all shared libraries.
3361 * symmisc.c: include param.h to get CLEAR_SOLIB.
3363 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3365 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
3366 to 3.90.11. ChangeLog entries below are from this.
3368 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)

3374 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3378 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
3380 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)

3384 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3386 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
3387 Put parens around gcc_p in expansion.
3389 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3391 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
3393 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3395 * Changes for Sun shared libraries:
3396 blockframe.c (find_pc_partial_function): If a non-text symbol
3397 is found, set *address = pc - FUNCTION_START_OFFSET.
3398 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
3399 Disable breakpoints instead of giving an error.
3400 source.c (select_source_symtab): Initialize cs_pst.
3401 symmisc.c: Call CLEAR_SOLIB if defined.
3402 symtab.h: Make text{low,high} CORE_ADDR not int.
3403 (psymtab): New field addr.
3405 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
3406 (record_misc_function): Give correct type for N_DATA symbols.
3407 (condense_misc_bunches): do "misc_function_count = j" regardless
3409 Take code which is shared between symbol_file_command and
3410 add_file_command and put it into partial_symbol_file_{open,read}.
3411 Split add_file_command into add_file_command and add_file.
3412 Make psymtab_to_symtab read in the string table if the file
3414 Two new parameters to read_dbx_symtab and start_psymtab.
3415 tm-sunos.h: New file.
3417 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3419 * infcmd.c: Change cont_command to continue_command and "cont"
3422 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3424 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
3426 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
3428 * values.c (USE_STRUCT_CONVENTION): Check for structures of
3429 size 1,2,4,8 rather than size < 8.
3431 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
3432 as necessary, not just once.
3434 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3436 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3438 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3440 * tm-news.h: Add CALL_DUMMY_*.
3442 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
3444 * config.gdb: In list_host, list_target, use ${i}, not $i.
3446 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3448 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
3450 * sparc-opcode.h: Change all store floating-point state register
3451 instructions to have the right match & lose fields.
3453 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3455 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
3457 config.gdb: If srcdir != ., create readline directory and
3458 copy a makefile into it.
3460 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
3461 consistency with POSIX.
3463 * breakpoint.c (bpstat_stop_status): Disable watchpoint
3464 when we exit its exp_valid_block.
3466 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
3468 * Makefile.dist: Bump version to 3.91.3.
3470 * Clean up handling of breakpoint commands (somewhat).
3471 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3473 inferior.h: Add breakpoint_proceeded to inferior status struct
3474 and globals; save it and restore it.
3475 (clear_breakpoint_commands): Cleanup, remove old #define.
3477 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3478 (save_inferior_status, restore_inferior_status): handle it also.
3479 (proceed): Remove earlier code that set breakpoint_proceeded.
3480 It is now set only in clear_proceed_status.
3481 (clear_proceed_status): Cleanup, use bpstat_clear rather
3482 than clear_breakpoint_commands. No callers need the stop_bpstat
3483 between clear_proceed_status and proceed.
3485 infcmd.c: Add breakpoint_proceeded definition and comment.
3486 (cont_command, jump_command, signal_command): Move call to
3487 clear_proceed_status right next to call to proceed.
3489 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3490 caller's argument while running down the chain of breakpoints.
3491 Use new variable "breakpoint_proceeded" to determine when
3492 a command that it executes moves the inferior past the
3494 (bpstat_clear): Handle NULL argument.
3495 (bpstat_clear_actions): Avoid useless call to
3496 breakpoint_auto_delete.
3497 (delete_breakpoint): Clean up bpstat's that are pointing to
3498 the deleted breakpoint from the stop_bpstat chain.
3499 (breakpoint_auto_delete): Simplify.
3501 * Clean up handling of EOF, error on stdin, etc. This was
3502 prompted by a network problem that caused gdb to go into an
3503 infinite loop filling up its malloc'd memory.
3505 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
3506 not clear_breakpoints_commands, which is now gone.
3507 (main): If command_loop returns (e.g. from EOF on stdin), do
3508 a quit_command (looping back to command_loop if quit_command
3509 doesn't really quit).
3510 (command_loop): check result from command_line_input and
3511 exit if it returns NULL, rather than passing the NULL to
3513 (gdb_readline): Free malloc'd result space before returning
3516 * utils.c (query): Handle C-d to mean "yes", just as if the
3517 input was not a terminal. Also avoid infinite loop if EOF
3518 occurs in mid-input-line before newline. This allows
3519 query to be used at EOF on stdin with reasonable results.
3521 * infrun.c (proceed): Set breakpoint_proceeded.
3523 * values.c (value_as_long): Avoid infinite recursion for enums.
3524 (_initialize_values): Fix typo in help msg (kingdon).
3526 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
3527 RL_LIB for linking. This allows -lreadline for linking
3528 and nothing for dependencies, once readline is a real library.
3530 * config.gdb: Jim Kingdon: give useful error message if the
3531 host or target type is not recognized.
3533 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
3534 it just defines it. Dumb, but deal with it.
3536 * Jim Kingdon suggests:
3537 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
3539 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
3541 * Makefile.dist (VERSION): Bump version # to 3.91.2.
3543 * Clean up Bothner's changes.
3545 * blockframe.c (clear_pc_function_cache): New function.
3546 * blockframe.c: remake cache_pc_function_* static.
3547 * dbxread.c (symbol_file_command): remove references to
3548 cache_pc_function_* variables.
3549 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
3550 * printcmd.c: Avoid kludging a global variable (addressprint)
3551 to avoid printing the address of a string twice. Instead,
3552 pass the format letter 's' down low enough that it can be seen
3553 to avoid this problem.
3554 (print_formatted): Pass format arg to value_print.
3555 (restore_addressprint): Remove function.
3556 (do_examine): Avoid hacking addressprint, cleanups and such.
3557 (print_frame_args): Add a comment to a Bothner change.
3558 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
3559 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
3560 to wipe out the values cached in blockframe.c.
3561 * symtab.c (find_method): Add comment saying how big you must
3562 allocate to be "big enough". Per being terse again.
3563 * valprint.c (val_print): Handle format letter "s" to print
3564 strings without addresses. Add comment to vtbl printing code
3565 which casts with wild abandon. Rearrange reference-printing
3567 @0xaddr: value (print w/addressprint)
3568 value (print w/~addressprint)
3569 @0xaddr (parameter lists w/addressprint)
3570 or nothing (parameter lists w/o addressprint)
3572 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
3574 * Merge more changes from Per Bothner:
3576 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
3577 annoying) that I tried to improve it. Here are my suggestions.
3579 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
3582 Do automatic de-reference when taking the address of a reference.
3584 Don't deref_ref when printing parameter lists.
3586 More attempts at treating refernences properly.
3588 In val_print, if deref_ref==0, don't print dangling " = ".
3590 Add COERCE_REF macro, which de-references an REF.
3592 * Merge changes from Per Bothner:
3594 * Fixed (Sony news)-specific configuration problems.
3595 * Fixed other problems with using vanilla pcc and libc (enum problems;
3596 assumption that vsprintf exists).
3597 * Some major speed-ups (finc_pc_partial_function now caches a match;
3598 parsing avoids duplicate symbol_lookup calls).
3599 * Changed handling of baseclasses (no longer use baseclasses field
3600 of struct type, use the first n_baseclasses fields instead).
3601 * Various minor changes/fixes, most C++-related.
3604 Cache the most previous match from find_pc_partial_function.
3605 (Save both low and high ends of matching function's pc range.)
3606 This speeds up the loop of infrun.c:wait_for_inferior quite
3607 a bit, and makes step/next commands much zippier.
3609 Added an enum->int cast (otherwise, some compilers barf).
3611 No longer set baseclass offset to 0, since multiple
3612 inheritance now mostly works.
3613 Added a number of casts, to shut up compiler warnings
3614 (after stabs where made enums, not ints).
3615 When discarding a symbol table (in symbol_file_command),
3616 must clear the cache introduced in blockframe.c.
3617 Don't convert $vtbl_ptr_type to vtbl any more.
3618 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
3619 Mask off sign bit emitted by g++ for virtual table offset.
3620 Set voffset to -1 (not 1) for static member functions.
3622 Changed parsing/lexing of names to avoid doing symbol lookup twice
3623 (once when lexing to determine symbol class, once for real).
3624 Now only call symbol_lookup once. Fields of 'this' win especially big.
3626 Subpress printing addr twice in the case of 'x/s addr'.
3628 lookup_basetype_type is no longer used.
3629 Add find_methods as recursive helper function to decode_line_1.
3630 This allows multiple inheritance to work.
3631 Also, once one or more matches has been found, do not look in
3632 base-classes. (Baseclass methods would be overridden, anyway.)
3634 Removed baseclasses array in struct type.
3635 Instead of using baseclasses[i], use fields[i-1].
3636 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
3637 Changed sign convention of voffset (previous was inconsistent).
3639 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
3641 Used to assume existence of vsprintf. Re-written to not need it
3642 if HAVE_VPRINTF is undefined.
3644 typecmp was too pessimistic. Made it less so.
3646 Don't print space after address.
3647 If vtable points to a misc symbol (with 0 offset), print it,
3648 since that indicates the actual class of the object.
3649 Changed ype_print_derivation_info to use new inheritance
3650 scheme (without baseclasses vector).
3652 In value_primitive_field, fixed some bugs left over from previous set of fixes.
3653 Also, changes needed because TYPE_BASECLASSES were removed.
3655 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
3657 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
3660 If there is no path set, and the symbols don't indicate what directory
3661 a file was compiled in, look in the current directory. But either
3662 a path or a known compilation directory will prevent this.
3665 Three independent bug fixes:
3666 * Remove the #if 0 block that breaks some stuff.
3667 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
3668 adapt gdb to either SunOS 4.0.* or 4.1.
3669 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
3672 Instantiate the class T when looking for methods in it. (Tiemann@sun)
3675 (type_print) Demangle the name being printed.
3676 (type_print_base) Handle botched demangling without coredump (tiemann).
3679 (check_stub_method): Document routine.
3680 (tiemann) fix bug for no-arg functions
3681 Avoid clobbering beyond end of malloc'd storage.
3682 Terminate the argument list properly.
3684 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
3686 * Changes merged by John Gilmore:
3689 In breakpoint_1, use new print_address_symbolic instead
3690 of find_pc_partial_function. (This forces use of assembler-level
3691 addresses, and avoids misleading non-mangled source-level names.)
3693 Generalize ansi argument such that -1 means skip arglist totally.
3694 Removed global variable print_ansi_qualifiers (which made
3695 code non-reentrant), in favor of extra explicit arguments
3696 to internal routines.
3698 Add new helper function print_address_symbolic.
3699 Use find_pc_misc_function instead of find_pc_partial_function
3700 (since we want assembler-level symbols here).
3702 Print unknown function as just "f (...)", not "f (...) (...)".
3703 Use new fputs_demangled explicitly.
3705 Fixed a typing violation (problem: value.h cannot be imported
3706 without renaming many variable in this file).
3707 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
3708 decode_line_1: Moved forward some never-reached code.
3709 Made decode_line_2 skip function prologues correctly.
3711 fputs_filtered should not demangle by default.
3712 Add new fputs_demangled to demangle on demand..
3714 Change value_struct_elt to use value_primitive_field (using recursive
3715 utility function search_struct_field). This allows foo.bar to work
3716 for multiple inheritance (so far only for data fields).
3717 Change check_field in the same way (recursive helper function
3718 to support multiple inheritance).
3719 (Note: there are more of these problems that I haven't fixed.
3720 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
3721 value_of_this: 'this' symbol name is now just "this", note "$this".
3723 Don't print static members.
3724 Avoid printing "members of <type>" if there are none.
3725 Simplified type_print_derivation_info by merging duplicate code.
3726 Remove useless blank lines in type_print_base (ptype command).
3728 Added declaration of new routine value_primitive_field.
3730 Added value_primitive_field which is generalized version of
3731 value_field that can handle multiple inheritance (non-zero offsets etc).
3732 Re-implemented value_field to call value_primitive_field.
3734 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
3736 * infcmd.c -- insert else to avoid 'delete env' coredump when you
3737 delete the whole environment. Karl Berry reported the bug.
3738 * source.c - fix openp to avoid //'s in filenames, which
3739 trigger an Emacs bug causing it to not be able to find files
3740 when running gdb in a window.
3741 * dbxread.c - zap the #if 0 that botches the add-file code.
3742 It seems to work a lot better without all the code commented out.
3744 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
3746 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
3749 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
3751 * Makefile - added a ${CFLAGS} to a couple of entries,
3752 added remote-sa.sparc.c
3753 * added remote.sa-sparc.c, a modification of remote.c
3754 which conducts a dialog directly with the SparcStation prom.
3755 * breakpoint.c, infrun.c, sparcdep.c added
3756 remote_insert_breakpoint(), and remote_remove_breakpoint()
3757 to breakpoint.c instead of directly writing breakpoint instructions.
3758 * sparcdep.c on remote_debugging,there is no need
3759 to remove signle step breakpoint instructions.
3760 * main.c added "-epoch" flag and "int epoch_interface" to main.c
3762 * printcmd.c - epoch interface sends lisp expressions to open up
3763 epoch windows on inspection.
3764 * valprint.c - added arrayprint, and addressprint and made adding
3765 format controls easier
3766 * wait.h added a couple of undef's because we were getting
3767 complaints about WSTOPSIG and WTERMSIG begin redefined.

3792 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
3794 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
3795 should print ANSI qualifiers (such as `const' and `volatile').
3796 All callers changed to call with ANSI == 1, except from
3797 `check_method_stub', which uses old-style syntax.
3799 * symseg.h (struct fn_field): Remove unneccessary `args' field.
3800 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
3802 * values.c (check_stub_method): New function.

3819 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
3821 * blockframe.c (blockvector_for_pc): New function.
3822 * blockframe.c (block_for_pc): Changed to call
3823 `blockvector_for_pc' and get the block itself.
3825 * stack.c (catch_info): New function. Prints info about
3826 exceptions which can be caught in the current frame.
3827 * stack.c (print_frame_label_vars): New function. Similar to
3828 `print_frame_local_vars'.
3829 * stack.c (print_block_frame_labels): Prints out labels that are
3830 defined in this frame. These labels are exceptions that can be

3835 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
3837 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
3838 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
3839 when printing the type.
3841 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
3843 * valprint.c (val_print): Use `baseclass_addr' to access the
3844 baseclasses pointed to via the derived class object at VALADDR.
3846 * values.c (baseclass_addr): New function. Casts derived pointers

3854 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3856 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
3857 exp_valid_block field correctly.
3859 * infrun.c (wait_for_inferior): When checking "don't even think
3860 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
3861 also check step_resume_breakpoint.
3862 Insert breakpoints and continue (not step) if
3863 step_resume_break_address != NULL, even if another_trap.
3864 If trap_expected and we enter sigtramp, then set up a
3866 If trap_expected is set when we hit the step_resume_break,

4030 to remote_fetch_registers.
4032 * mips-tdep.c (_initialize_mipsdep): Remove hex_disassembler
4033 and re-write skip_prologue to use add_set_cmd.
