3 * doc/gdb.texinfo: finished using all RMS comments, save those for
4 appendices on readline and cmd history (which are in other source
7 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
9 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
10 chapter 9; (2) documented 'break' command's menu mode for
11 overloaded names, in response to hgs problem report C++ p-31
13 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
15 * doc/gdb.texinfo: (1) better introductory example; (2) more
16 consistent use of @code, @samp, @file, @kbd throughout; small
17 cleanups to first three nodes; (3) new "Contributors" node;
18 (4) Appendix, Renamed Commands; (5) divert specialized startup
19 instructions to "Targets" chapter for generic manuals, while
20 leaving them up front for manuals specific to specialized
21 environments; (6) apply fixes from RMS comments through chapter 4.
23 * pretex.m4: modify explanatory text slightly (and redefine
24 "regexp") to keep GNU m4 from complaining. (It still crashes
25 later, but one step at a time...)

29 * readline/readline.c (update_line): Avoid dereferencing a pointer
30 before comparing it to its bounds. Saber caught this.

36 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
37 stuff for config manual) here where it counts; updated
38 to use new subdir structure (gdb/doc/).
40 * Makefile: generated from above via
44 * gdbint.texinfo: added instructions on generating gdb.info* files
45 locally for release. These are ordinary info
46 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
47 Makefile)---but due to use of texinfo 2, can't count on makeinfo
48 to generate these, so we distribute them already formatted.
50 * gdb.texinfo: included full Info node and menu crud (as generated
51 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
53 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
54 put in comments-for-future gdb.info target (one day makeinfo will
57 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
59 * gdb.texinfo: Updated to include new or old undocumented
60 commands, at least the following (perhaps some others I forgot to
61 record): info f, info float, info path, info program, info s, info
62 set, info source, info terminal, info types, info user, set/show

68 * mipsread.c: Rather than keeping count of how many symtabs
69 and psymtabs we have, for sorting purposes, count them when
70 we need to sort. This fixes bug in rereading of symbol tables.

96 * remote.c: Remove decls of memory_insert_breakpoint
97 and memory_remove_breakpoint, no longer used. (Suggestion of
100 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
101 to make it easier to interface to "configure"'d libraries.
103 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
105 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as

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

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

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

637 Rename add-syms to add-symbol-file.
639 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
641 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
642 * symfile.c (clear_symtab_users_once, cashier_psymtab,
643 free_named_symtabs): Move these routines from symmisc.c.
644 * symmisc.c (same): same.
645 (free_symtab): Make non-static.
646 * symtab.h (free_symtab): Declare as exported void fn now.
647 * dbxread.c (end_symtab, end_psymtab): Change comments.

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

1001 (): FIXME: Should realloc-down the psymbol lists when done reading
1002 the main symbol file?
1004 * symmisc.c (free_symtab): Free fullname field too.
1006 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1007 (REGISTER_ADDR): Make result type unsigned int.
1009 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1010 define REGEX must also define REGEX1 (its dependency).

1047 in raw hex as well as float format, regardless of whether it is
1048 a "virtual" convertible register.
1049 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1050 regs as a double, just in case it's being used that way.
1051 * values.c (unpack_long): Comment on array/function coercion.
1052 (unpack_double): Argument is in target byte order now. For
1053 integer arguments, just call unpack_long and float the result.

1055 * remote-nindy.c: Use ieee-float stuff.
1056 (nindy_fetch_registers): Unpack double regs to host double, then

1070 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1072 * coredep.c (fetch_core_registers): Pass end-address of register

1123 * inftarg.c (child_detach): Pop the child_ops vector if the
1124 detach is successful.
1125 * remote-nindy.c (nindy_create_inferior): Don't push a new
1126 nindy_ops since nindy uses the same one for execution and memory
1128 * core.c (core_ops): Use child_attach and child_create_inferior
1129 rather than default attach and create_inferior functions.
1131 Handle floating point registers in core files.
1133 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1134 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1135 This version untested since BFD doesn't yet support sun3 core
1137 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1138 conventions. Fix comments and style. This version has not
1139 been compiled yet, since we have no HP inhouse.
1140 * core.c (get_core_registers): Look for two sections, ".reg"
1141 and ".reg2", and pass both to fetch_core_registers sequentially.
1143 Revise directory path yet again.
1145 * source.c (forget_cached_source_info): Not static any more.
1146 (init_source_path): New default source path is "$cdir:$cwd".
1147 (dir_command): Handle variable arguments ($cdir, $cwd).
1148 (source_info): Print "Compilation directory" rather than
1149 "Originally compiled in" to remind people of $cdir.
1150 (openp): If the path contains $cwd, use current directory.
1151 (open_source_file): If compilation directory is known, replace
1152 first $cdir in path with the compilation directory.
1153 (print_source_lines): Even if we can't print the lines, set the
1154 current symtab and line for future commands like "info source" or

1156 line number, and file access error message.
1157 (_initialize_source): Fix help text to describe changes.
1158 * main.c (cd_command): Forget cached source info when we chdir.

1164 Byte-swap COFF symbol tables if necessary when reading them in.
1165 Use complain() to replace error message in one spot. Needs
1166 corresponding change in bfd/coff-code.h to make some symbol
1167 swapping routines non-static.
1169 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)

1181 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1183 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1184 <rpc/rpc.h> and <rpc/types.h>.
1186 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1188 * i960-tdep.c (examine_prologue): Add new argument limit,
1189 which stops the scan at the end of the prologue, or at the PC.
1190 This fixes a problem where it walks down into the code for the
1191 user's statements if that code looks like function prologues.
1192 Mark Fox and I have been bouncing this code back and forth, making
1193 small changes to it. Callers changed to match.
1195 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1197 Cleanup for gdb-3.94 release final:
1199 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1200 the .c files from vx-share and nindy-share, from the various
1201 macros, since they are not found via ALLDEPFILES.
1202 (SFILES): Add tm-i960.h.
1203 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1204 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files

1211 * am29k-tdep.c: Add contribution line.
1212 (examine_prologue): Cache information about function prologues in
1213 the misc-function-vector to avoid lots of references over the
1214 serial line while examining instructions.
1216 * core.c (core_close): New function made from cleanup_core.
1218 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1219 remote-vx.c, remote.c, target.c, target.h,
1220 Update target_ops vector to add attach, close, and load entries.
1221 Use add_syms_addr_command, not add_file_addr_command, for
1222 add_file. Break out close routine from existing code.
1224 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1225 they are in an obstack.
1226 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1228 (define_symbol): Add symbol type parameter; change callers;
1229 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1230 it to influence the symbol class on the i960.
1231 (define_symbol): Swap LOC_CONST's into target byte order.
1233 * exec.c (exec_close): New function.
1234 (exec_file_command): Call it.
1236 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1237 Fix byte order of frame pointer.
1238 (read_var_value): Result of 0 if var's value can't be found,
1239 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1240 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1241 (locate_var_value): Use read_var_value and use its lazy address
1242 as the location of the var's value. Lint.
1244 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1247 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1248 obsolete Intel versions in favor of vxgdb versions.
1249 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1250 code dealing with byte order of values, which Intel did in host byte
1251 order rather than gdb-4's target byte order.
1252 (i960_frame_chain_valid): Move to nindy-tdep.c.
1253 (examine_prologue, skip_prologue, frame_find_saved_regs,
1254 frame_args_address, leafproc_return, saved_pc_after_call,
1255 pop_frame): Add vxgdb versions from Mark Fox.
1256 (examine_prologue, frame_struct_result_address): Add code
1257 to deal with the saved value of G13 (struct return address
1259 (frame_args_address): Modify Mark's version to prefer the
1260 saved value over the current value in the topmost frame.
1261 Cache result in the frame info to avoid performance hair in
1263 (print_fault): Add gdb960 code for printing faults.
1264 (_initialize_i960): Actually call check_host.
1266 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1267 add stub routines. FIXME, these currently just return zero!

1270 (attach_command): Call target_attach, not target_open, now.
1272 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1273 (child_attach): Rename from child_open.
1274 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1275 don't confuse it with a zero step_resume_break_address.
1277 * inftarg.c (child_detach): Eliminate inferior_pid test.
1278 (child_files_info): Clean up message a bit.
1279 (child_ops): Use child_attach, not child_open, to attach.
1281 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1282 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1283 findvar.c to here, since it depends on the contents of the
1284 shadow_contents of breakpoints, but keep if #if 0 since it is
1287 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1290 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1291 (ptype_command, display_command): Eliminate have_inferior_p and
1292 have_core_file_p in favor of target_has_stack or
1293 target_has_execution.
1294 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1295 code for actually finding the values of arguments, though we still
1296 keep track of the maximum stack offset for use in printing unnamed
1297 arguments. Handle missing FRAME_ARGS_ADDRESS.
1299 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1300 (struct nindy_regs): Define registers passed to/from nindy.
1301 (nindy_fetch_registers, nindy_store-registers): Translate between
1302 nindy and GDB formats for the registers.
1303 (dcache_init): Statically allocate the cache, since it was being
1304 allocated by a malloc that was never freed anyway.
1305 (nindy_create_inferior): Error, not core dump, if no exec file.
1306 (nindy_before_main_loop): Use target_load, not target_add_file.
1308 * remote-vx.c (net_load): Specify large timeout for load
1309 requests. Allow user to break out with INTERRUPT.
1310 (net_break): Remove useless code, clean up. Change callers.
1311 (parse-args, skip_white_space, find_white_space): Clean up arg
1312 parsing to cope with quoted strings.
1313 (net_wait, net_quit): Never call error, just return status.
1314 (vx_read_register, vx_write_register): Cleanup status checking.
1315 #ifdef the code based on which CPU we are using (960 or 68k),
1316 FIXME, this should be completely general but it isn't yet.
1317 (vx_xfer_memory, vx_resume): Cleanup status checking.
1318 (vx_run_files_info): Improve message.
1319 (vx_load_command): Renamed from vx_add_file_command. Allow load
1321 (net_ptrace): Remove unused routine.
1322 (vx_wait): Adopt code from vxgdb960 to cope with broken
1323 connections to target machine and prompt to disconnect. Remove
1324 debug printouts. Map some EVENT_'s to SIGnals.
1325 (add_symbol_stub, vx_open): Print names of object files we found,
1326 and "ok" if we read their symbols OK. Clarify output in general.
1327 (vx_attach, vx_detach, vx_kill): Add these commands.
1328 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1329 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1330 "info files" output, and create_inferior, since we already have
1333 * stack.c (frame_info): Replace Frame_unknown with 0.
1334 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1335 (return_command): Pop until the PC matches as well as the FP,
1336 so it works even if the FP is shared with another function,
1337 as in "frameless" or "leaf" procedures.
1339 * symfile.c (load_command): renamed from add_file_target_command.
1340 (add_syms_addr_command): renamed from add_file_addr_command.
1341 (add_syms_command): Stub to call target_add_syms.
1342 (_initialize_symfile): Change command names and descriptions,
1343 add-file => add-syms, and load from alias to its own command.
1345 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1346 maybe_kill_then_create_inferior): Default for attempts to start
1347 a process, if one is already running, is to ask about killing
1348 it and retry if yes.
1349 (upstack_create_inferior): #if-0 it, strata obsolete it.
1350 (push_target, unpush_target, pop_target): to_close() a target
1351 before unstacking it.
1352 (target_info): Renamed from target_files_info.
1353 (_initialize_targets): Rename "i files" as "i target", accessible
1356 * target.h: Improve comments about the target_ vectored routines.
1358 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.

1361 (SKIP_PROLOGUE): No longer a no-op.
1362 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1363 (*_REGNUM): Sort register numbers.
1364 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1365 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1366 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1367 are now 10 byte extendeds, not 8 byte doubles.
1368 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1369 for nindy versus vxworks targets. FIXME, this should possibly go
1370 in the target vector.
1371 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1372 frame_saved_regs and arg pointer with each frame.
1373 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1374 (FRAME_ARGS_ADDRESS): Use cached result.
1375 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1376 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1377 (PRINT_RAMDON_SIGNAL): Call print_fault.
1378 (POP_FRAME): Now works.
1380 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1381 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1382 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1383 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1386 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1387 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1389 * valarith.c (value_subscripted_rvalue): Avoid handling
1390 floats and doubles specially; it gave alignment errors. Lint.
1392 * valops.c (value_of_variable, value_of_this): Error if unknown
1395 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1396 to avoid alignment problems.

1398 (cplus_val_print): Two args are ignored; remove them. Change caller.
1399 (val_print): Use unpack_long rather than pointer-deref.
1402 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1403 to avoid alignment problems.
1404 (value_being_returned): Error if return value unknown.
1405 (set_return_value): Add bogosity warning, FIXME. *
1407 * TODO: A woman's work is never done.
1409 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1410 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1411 Add ieee-float.o to OBS.
1412 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1413 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1414 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1416 Changes to generalize the VxWorks RPC protocol slightly, to handle
1417 i960 as well as 68000.
1419 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1420 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1421 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1422 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1423 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1424 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1425 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1426 so they will move in target byte order rather than network
1427 byte order (happens to be the same).
1429 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1431 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1433 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1436 Add contribution lines to various files, showing where they
1439 * breakpoint.c (break_insn, check_break_insn_size,
1440 read_memory_nobpt): Remove to mem-break.c.
1442 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1445 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1446 entry has bad register number. This change is not
1447 tested in this release, FIXME.
1449 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1452 * value.h: Force value's contents field to be aligned to hold
1453 at least a double or a long long (if supported). This avoids
1454 doing bcopy's in and out of the contents field.
1456 (step_1): Avoid coredump under obscure circumstances when we
1459 * symtab.h (misc_info): Add field to misc function vector for
1460 any kind of cached information the target code desires. AMD
1461 29000 uses this to avoid repeating examine_function_prologue's.
1463 * coffread.c: Lint. Remove static symfile, read_section_header.
1464 core.c (have_core_file_p): Lint: remove.
1465 expprint.c (print_subexp): Lint.
1466 infptrace.c, valops.c, valprint.c: lint.
1468 Roll in changes from vxgdb-5.0.1:
1470 * symtab.h: Comment byte order of each address class. Add
1471 LOC_LOCAL_ARG for frame-relative args (960).
1472 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1473 symtab.c, symmisc.c: ditto.
1475 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1477 * remote.c (remote_resume): Error if resume with a signal.
1479 * symfile.c (prim_record_misc_function): Clear misc_info.
1480 (fill_in_vptr_fieldno): Check stub type of arg.
1482 * valops.c (value_cast): Avoid looking up names of types whose
1483 name we don't know, to prevent coredump. Sun CC produces typedef
1484 rtx and the name of *rtx is zero...
1486 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1488 Roll in changes from final AMD 29000 port (Tiemann).
1490 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
1491 for ../include/a.out.encap.h. This might not work now that BFD
1492 is separately compiled. Instead, BFD support for encap will have
1493 to translate machine type 29k into the right COFF_MAGIC.
1495 * infcmd.c: Remove references to inferior_pid that aren't used
1496 in actual ptrace calls; use target_has_execution, etc.
1497 (have_inferior_p): Remove function.
1498 (program_info): Print target info rather than "process number";
1499 avoid gratuitous messages unless from_tty.
1500 (run_stack_dummy, finish_command): Set proceed_to_finish.
1501 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
1502 main.c: Lint. Lose have_inferior_p().
1503 inferior.h (have_inferior_p): Remove, lint.
1504 (proceed_to_finish): Add flag to ask that all regs be saved
1505 by normal_stop, for the few commands that need it, speeding up
1506 serial I/O. Add comments to stop_registers.
1508 * remote-eb.c: Remove newline from breakpoint message we grep
1509 for. Never time out when running the user program.
1513 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1515 Roll in changes from vxgdb-5.0.1:
1517 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
1518 symbol in its raw form, we are processing an unlinked ".o" file.
1519 See if the target environment has assigned it an address, using
1520 target_lookup_symbol (VxWorks does), and enter it into the symtab
1523 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
1524 68k versions for a simpler version that assumes zero FP at bottom.
1525 Fixes bug of truncated stack reports.
1527 * target.h (target_lookup_symbol): Define this routine's args
1528 and result, finally.
1530 * target.c (nosymbol): Default routine for target_lookup_symbol.
1531 (target_default): Default lookup_symbol and call_function too.
1532 (files_info): Only print has_all_memory warning if a non-dummy
1535 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
1536 vx_convert_from_virtual): If target does not have floating point,
1537 zero register "values", and avoid doing cross-net conversions.
1538 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
1539 (vx_open): Rearrange code that attaches to target and reads
1540 symbols for all loaded modules, to work if some of the modules
1541 are not accessible. Add symbol_stub() and add_symbol_stub()
1542 as callbacks from catch_errors(). Allow connect attempt to be
1543 interrupted painlessly with ^C (FIXME, there are still some bugs
1544 if the interrupt happens during symbol reading.). Print
1545 final message with puts_filtered, since symbol messages are
1550 * main.c (catch_errors): Only print errstring if non-null.
1551 (command_loop): Avoid an ioctl per command to test ISATTY.
1553 * remote-vx.c (net_load): make static; avoid sophomoric msg.
1554 (vx_xfer_memory): Return correct result!
1555 (vx_files_info): Indicate whether target has float or not.
1556 (vx_lookup_symbol): Complain, not error, if target gone.
1557 (vx_open): Print "Connected" msg before disabling immediate-quit.
1558 [FIXME: lookup_symbol and vx_open changes need testing.]
1560 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
1561 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
1562 contributor lines and update copyrights to 1991.
1564 Changes from an attempted H-PUX host port:
1566 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
1567 defines PT_ATTACH and PT_DETACH but not PT_KILL.
1568 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
1569 * remote-vx.c: include <sys/time.h> for HPUX.
1570 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
1571 "core_file_command" routine to BFD regime. May not work yet.
1573 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
1575 * xgdb.c: Replace X10 version with some VJ version.
1576 (FIXME: Its copyright assignment is not on record.)
1577 * xgdb.c: Update include files to X11R4 (Xaw crud).
1578 (xgdb_display_source, create_text_widget): fix call to
1579 get_filename_and_charpos. Rewack source window stuff for X11R4
1580 (gleaned from include files, and "nm's" of binary libraries, since
1581 I had no doc available).
1582 (append_selection, append_selection_word): Disable with FIXME
1583 since R4 changed interface here.
1584 (create_buttons): Add back the old set of buttons.
1585 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
1587 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
1588 Roll VERSION to 3.94 (not yet final though).
1590 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1592 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
1593 obstack_int_grow, obstack_int_grow_fast): Eliminate
1594 cast on left of assignment, which gives MIPS cc fits and is
1597 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
1598 F_ALIAS. Use printf, not fprintf, when not passing a file
1600 (compare_opcodes): Check that identical instructions have
1601 identical opcodes, complain otherwise.
1603 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
1604 was reported by Roland McGrath.
1605 (unimp): Only match if exactly zero instruction. (Roland)
1606 (branches and traps): Generate all variations of these
1607 instructions with macros, based on a single call that defines
1608 each condition name and its binary representation.
1609 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
1611 * valprint.c (val_print_fields): Take, and use, format parameter.
1612 This means that "p/x struct" again prints the elements in the
1613 desired format. Changed callers.
1615 * stack.c (frame_info): Use filtered output, and indicate wrap
1616 points. Remove kludgy formatting designed to avoid line wrap.
1618 * utils.c (wrap_here): If the line is already full (because
1619 we had printed a long indent or long wrapped string), do an
1620 immediate newline-and-indent.
1622 * m68k-pinsn.c (print_insn_arg): Bugfix from
1623 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
1624 instruction is incorrectly disassembled as bkpt #8.
1626 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
1627 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
1628 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
1629 and then will dump core (sometimes). I traced it back to an
1630 uninitialized symfile_name in psymtab_to_symtab.
1631 (const_vol_complaint): Add quotes to message.
1632 (define_symbol): Only believe line number if gcc_compiled.
1633 Avoid allocating symbol if we will not return it.
1635 Add target strata support so that newly established targets go
1636 into their right place in the target stack (e.g. a new exec file
1637 doesn't wipe out the ability to access the running process).
1639 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
1640 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
1641 and initialize it properly in all the targets.
1643 * target.h: Document strata. Change return type of push_target.
1645 * target.c (nomemory): new function for dummy memory access.
1646 (tcomplain): Rename complain, now also used in symfile.c.
1647 (push_target): Push targets within strata. New return value shows
1648 whether new target is on top of stack or not. Always keep dummy
1650 (target_files_info): Ignore dummy target.
1652 * core.c (core_open): Warn user, and skip accessing file, if the
1653 core target is not the topmost target in the stack.
1654 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
1657 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
1658 target_ops, it doesn't belong there since we have no regs there.
1659 Change name of target from machine => memory to clarify.
1661 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
1663 * Freeze version 3.93 for release.
1665 * Makefile.dist: Handle vx-share and nindy-share subdirs
1666 properly when building gdb.tar.Z.
1668 * symtab.c: lint; add no_symtab_msg to consolidate the messages
1669 printed in various places, so I could change just one copy.
1671 * dbxread.c, coffread.c: Change references to bfd->iostream
1672 to cast to FILE *, now that BFD avoids needing types defined
1673 in other header files.
1675 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1677 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
1678 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
1679 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
1680 (actually gcc -Wall).
1682 * dbxread.c: Remove first_global_sym, last_global_sym, since
1683 they are never referenced.
1685 * defs.h (baud_rate): Declare.
1686 main.c: Define it, and add the -b option to set it.
1688 * gdb-int.texinfo: Add text on how to define a new host or target
1689 architecture, prompted by Per Bothner's questions about MIPS
1692 * gdb.texinfo: Document "complaints". Change doc of -q since
1693 gdb no longer prints the copyright and blurb if you specify a file
1694 name to be debugged (just like Emacs). Add doc for Nindy-specific
1695 command line flags for specifying target serial port and such.
1696 Update copyright to 1991.
1698 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
1699 has taken over for us the job of ripping up executable files. The
1700 crud caused Per Bothner's port to not compile.
1702 * infrun.c (normal_stop): Avoid printing "Program exited
1703 normally" if we are in batch mode. This allows a GDB which
1704 executes a program on a target system, to behave like a Unix
1705 command (input from stdin, output to stdout, no extraneous
1708 * main.c (main): Allow additional machine-dependent command line
1709 options to be specified with the ADDITIONAL_OPTIONS,
1710 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
1711 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
1712 processing to occur just before the main loop with
1713 BEFORE_MAIN_LOOP_HOOK.
1714 (main): If a "core file" argument is specified, and it is not a
1715 core file, try it as a process ID to attach.
1716 (symbol_completion_function): Attempt to cope with
1717 "show screen-" TAB, not very successfully. This needs more work,
1719 (batch_file): New function, returns whether we are reading
1720 commands from an interactive tty on stdin, or from somewhere else.
1721 Called by normal_stop since it doesn't get from_tty passed down
1722 to it like many commands do.
1724 * remote-nindy.c: Handle command line options for nindy
1726 (nindy_before_main_loop): Prompt user for tty name if they
1727 don't specify it before getting to the interactive command loop.
1729 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
1730 and -r command line options. Also add hook before main loop
1731 to make it easy to specify a tty.
1733 * TODO: More things to do, one done.
1735 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
1737 * dbxread.c: Make complaint() calls pass pointer, not struct.
1738 Add complaints about badly formatted C++ type information
1739 (const/volatile indicator, and parse errors resulting in
1740 error_type). Fix C++ virtual member fn comment.
1741 (read_struct_type): Avoid bumping pointer if we got a parse
1742 error; this prevents our walking beyond the end of a string.
1743 Terminate loop on null char as well as semicolon.
1744 (process_one_symbol): Fix the LBRAC fix so that it uses the
1745 last previous SLINE, FUN, or SO record's PC address. C++ debug
1746 symbols did not have SLINE records in a useful order compared
1747 to the LBRAC records.
1748 (define_symbol): Handle "catch" records.
1750 * symtab.c (check_stub_type): Added new complain
1751 `stub_noname_complain' and added a consistency check to
1752 keep the debugger from crashing when finishing from an
1753 exception frame. A real fix will be needed later.
1755 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1757 * infcmd.c (attach_command): Make global.
1759 * Makefile.dist (REMOTE_OBS): Make these compile by default,
1760 but make them easy to comment out. Perhaps later they should
1761 be enabled by what CPU you configure for? FIXME.
1762 (VERSION): Roll to 3.93.
1763 (pinsn.o): Remove rule for obsolete file.
1764 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
1766 Run down a problem that manifested by printing the wrong function
1767 name in stack traces of read_ofile_symtab. Turned out that the
1768 problem was the SunOS 4.1.1 (and previous) C compiler outputs
1769 the LBRAC symbol with an address in the *data* segment, which
1770 blew our binary search through the blocks.
1772 * dbxread.c: Use the complain() facility consistently to bitch
1773 about problems in the symbol file we are reading.
1774 (finish_block): Add code to check the nesting of the blocks;
1775 complain and Procrust them to fit if wrong.
1776 (make_blockvector): Check the order of the blocks, complain
1777 [but don't cope] if wrong.
1778 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
1779 symbols to be sure their PC value is greater than the last SLINE
1780 (line number) symbol we've seen, complaining and adopting the
1781 SLINE PC value if wrong.
1783 * symfile.h (struct complaint, complaint_root, complain,
1784 clear_complaints): Add.
1785 * symfile.c (complain, complaint_root, clear_complaints): Add
1786 facility to deal with non-fatal complaints and to regularize their
1788 (symbol_file_add): Clear complaint counters to allow new complaints.
1789 (initialize_symfile): Add 'set complaints' and 'show complaints'.
1791 * dbxread.c (dbx_symfile_read): Remember the address and size
1792 of the string table for the main symbol file, so we won't read it
1794 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
1795 to avoid reading the string table yet again. Lint.
1796 (throughout): Improve filtered output, including word wrap.
1797 (read_range_type): Improve Bothner's fix to handle other types too.
1799 * utils.c: Improve line wrap implementation. Handle unlimited
1800 width by making chars_per_line unsigned.
1801 (puts_filtered): New, easy, function.
1803 * defs.h (puts_filtered): add.
1805 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
1806 call the identical sort_symtab_syms() in symfile.c instead.
1808 * expread.y: Suggest the `file' command rather than `symbol-file'.
1810 * command.h (enum var_types): Add zinteger for seroable
1812 * command.c (do_setshow_command): Handle var_zinteger. Restructure
1813 nested if's into a switch.
1815 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
1816 we did not stop because of a breakpoint (it must have been for
1817 some other reason, like a "stepi"), so don't print anything.
1819 * symtab.c: Include <sys/types.h> all the time. Now that BFD
1820 doesn't include <sys/types.h>, old SunOS's require it for
1823 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
1825 A test port of gdb-3.92.6 to the Sony NEWS.
1828 Don't normally link in remote- or vx stuff.
1829 Some of it doesn't compile, and it wastes space for 99% of the users.
1830 Remove reference to no-longer-used HAVE_VPRINTF.
1831 Fixed BFD_DEP typo to BFD_DIR.
1833 Fix cast in arg to bfd_h_getlong.
1834 Make char *prefix be const.
1835 Fix how certain range types are mapped into builtin unsigned int types.
1837 Remove 2 #includes. They cause errors (on Sony, at least),
1838 and aren't needed (they wern't in earlier versions).
1840 print_address_symbolic should never demangle labels
1841 (since it prints *assembler-level* labels).
1843 [This was superseded by the change to printcmd below.]
1846 Add some "volatile" return types to avoid warnings.
1847 If MISSING_VPRINTF add vprintf function and not just macro
1848 (since vprintf is used in printcmd.c).
1850 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
1851 (The latter isn't grokked by some PCC-based compilers.)
1853 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
1855 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
1856 * nindy-share/coffstrip.c
1857 Added some forward declarations (otherwise, gcc complains
1858 about implicit extern redefined as static).
1860 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1862 Changes inspired by Per Bothner:
1863 * printcmd.c (print_address_symbolic): Take additional parameter
1864 specifying whether to demangle.
1865 (print_address): Pass in asm_demangle to control demangling.
1866 (print_address_demangle): New fn, takes explicit arg to control
1868 * utils.c: Add new vars demangle and asm_demangle, and let them
1870 (fputs_demangled): If !demangle, just print the argument.
1871 (fprint_symbol): If !demangle, just print raw symbol.
1872 * valprint.c (val_print): Call print_address_demangle rather than
1873 print_address, to cause demangling to depend on the global
1874 rather than assembler-level demangling setting.
1875 * WHATS.NEW, gdb.texinfo: Document.
1877 * main.c (show_command): Show all settings if no arg.
1878 (initialize_main): Make "info set" the same as naked "show".
1879 * command.c (cmd_show_list): Handle prefix commands in the
1880 list, and print the name of the setting as well as its English
1881 description and value.
1883 Allow gdb functions to specify where a line should wrap if it
1884 exceeds the size of a terminal line. Use it to make the output
1886 * utils.c (set_screen_width_command): New fn, mallocs a buffer
1887 of the right size when screen width changes.
1888 (set_screensize_command, screensize_info): Remove #if 0'd fns.
1889 (wrap_here): New fn, indicates a point in the output where we
1890 should wrap the line rather than just letting it overflow at a
1892 (fputs_filtered): Implement wrapping.
1893 (n_spaces): New fn, returns a pointer to N spaces.
1894 (print_spaces_filtered): Use n_spaces.
1895 * defs.h (n_spaces): Declare.
1896 * stack.c (print_frame_info): Wrap with 4-space indent after
1897 fn name and before filename and line number.
1898 * printcmd.c (print_frame_args): Wrap with 4-space indent
1899 before each argument name is printed.
1900 * valprint.c (value_print): Wrap with no indentation before
1902 (val_print_fields): Wrap with indentation relative to nesting
1903 level before each field name.
1904 (val_print): Wrap with nesting indentation before array elements.
1905 * command.c (do_setshow_command): Avoid extra newlines,
1906 wrap with 4-space indent around values printed, end with period.
1907 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
1909 * breakpoint.c (breakpoint_1): Implement addressprint for
1910 "info breakpoints" display. Change file name and line number
1911 format to " at file:nnn" rather than " (file line nnn)".
1912 * gdb.texinfo: Document.
1915 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1917 Frozen for gdb-3.92.6 release.
1919 README, WHATS.NEW: Update for 3.92.6 release.
1921 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
1922 coffread.o from configs since it is now built by default.
1923 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
1924 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
1925 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
1926 from configs since it is now built by default.
1928 Makefile.dist: Update for release 3.92.6. Handle files that
1929 have been moved to ../include, ../getopt, or ../bfd. Add
1930 saber.suppress and tests directory. Add config.status to
1931 the release (it will say "none").
1933 coredep.c: Minor formatting fixes.
1935 These changes were made in early December but only checked in now:
1936 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
1937 nindy-share/nindy.c: lint
1938 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
1939 register values coming back from the target; we store values
1940 in target byte order everywhere.
1942 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
1944 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
1946 * valprint.c (cplus_val_print, val_print_fields): New functions,
1947 which print C++ objects. They conspire to avoid printing a
1948 virtual base class more than once, following all the twists and
1949 turns of C++ virtual base rules.
1950 (val_print): Call the above rather than do it by hand.
1952 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
1953 symbol file, not for added files like shared libs. This really
1954 needs to be generalized to a timestamp per file.
1956 * core.c (cleanup_core): Avoid coredump if no core file.
1958 * config.gdb: Accept -host or -target in place of +host or
1961 * coffread.c (find_linenos): Avoid desupported BFD interface
1962 to line numbers. We still read them manually rather than using
1963 BFD's "generic" features.
1965 * gdbrc.tex, threecol.tex: Add GDB reference card and its
1967 Makefile.dist: Add refcard to OTHERS list for creating tar files.
1969 * Makefile.dist: Eliminate use of $< in explicit targets.
1971 * readline/Makefile: Use $< rather than $*.c, which does not
1972 include the VPATH in GNU Make.
1974 * tconfig/i960-bout, tconfig/i960-coff: These are identical
1975 copies of tconfig/i960, added for global configuration
1976 compatability. All i960 versions can read both coff and b.out.
1978 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
1979 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
1982 * TODO: Think of more things to do.
1984 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
1986 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
1987 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
1988 64-bit float conversion.
1990 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
1991 equivalent to sun?os4 so global config works.
1993 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
1995 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
1997 * main.c: Only declare linesize once; declare pagesize not at
1998 all, since it is never used.
1999 (main): Clear newly allocated line before it is used.
2001 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2003 Further stabilization for the Intel 960.
2005 * Makefile.dist: Parameterize the location of the "include"
2006 and "bfd" directories, as well as "getopt". Add symfile.c.
2007 Link in both dbxread and coffread. Fix up "make depend" to
2008 rewack the locations of include, bfd, and getopt in its output.
2010 * README: Document moving include files, improve some of
2013 * coffread.c: Move common code out to symfile.c. Change
2014 symbol_file_command style interface to use new *_symfile_init
2015 and *_symfile_read interface under BFD. Use BFD internal
2016 info to locate line table, symbols, etc.
2018 * core.c (core_fetch_registers): Rename to get_core_registers
2019 to avoid confusion with fetch_core_registers.
2020 (register_addr): Move to coredep.c, which is already machine
2021 dependent. This leaves core.c pretty clean of dependencies.
2023 * coredep.c (register_addr): Accept this routine from core.c.
2025 * dbxread.c: Move common code (with coffread.c, etc) into new
2026 symfile.c. Each psymtab now contains a pointer to the
2027 format-dependent function that knows how to read it in. Make
2029 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2030 (process_one_symbol): Add code to complain about a "compiler bug
2031 we muzzle here", if we actually see it.
2033 * eval.c (evaluate_subexp): Insert missing "break" statements
2034 in code that determines whether a variable is an lvalue in
2035 memory, register, or whatever. I detected this via a compiler
2036 bug in which it *almost* mashed out the whole switch statement.
2038 * gdb-int.texinfo: Add minor sections on configuring gdb for
2039 release, and about the README file.
2041 * infcmd.c (registers_info): Fix formatting somewhat. Still
2042 not as pretty as before, but it handles byte swapping.
2044 * remote-nindy.c: If data cache routines are interrupted while
2045 waiting for the remote end, be sure that any uninitialized cache
2046 blocks are on the free list, not on the valid list!
2048 * symfile.h: Flesh out this header file with all the various
2049 routines and variables that have been merged in from dbxread.c
2050 coffread.c, and symtab.c to symfile.c.
2052 * symfile.c: New file, containing code common to dbxread.c,
2053 coffread.c, and some code from symtab.c. All generic code for
2054 reading symbol files should be in here now.
2055 (unrecord_misc_function): Remove unused function.
2057 * symtab.h: Remove file-reading things to symfile.h.
2059 * symtab.c: Remove file-reading things to symfile.c.
2061 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2062 to decode i960 fault types.
2064 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2065 target.c: Change type of the "resume" function from int to void,
2066 since its result was never used.
2068 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2070 * main.c: Replace "stupid" with "caution"; you now "set caution
2073 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2075 * infcmd.c (do_registers_info): Call val_print to deal with the
2076 byte order of the registers being printed. FIXME, this makes
2077 the formatting of the output uglier.
2079 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2080 defined, call it for signals the debugger doesn't itself use.
2081 The i960 uses this for more detailed fault information.
2083 * remote.c (remote_open): If arg is null, print help rather than
2086 * sparc-xdep.c (register_valid): Avoid declaring size, since
2087 various modules will think of various sizes depending on the
2088 architecture of their tm-file. FIXME, we need protection against
2089 actually entering one of those modules, which would clobber
2090 storage if not for the target architecture compiled into gdb.
2092 * stack.c (up_command, down_command): Always print the frame
2094 (up_silently_command, down_silently_command): New commands
2097 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2099 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2100 more parameters than it used to.
2102 * findvar.c (registers): Increase slop to 256 bytes, which should
2103 protect us against even most RISC machines with large register
2105 (locate_var_value): Move declaration inside related ifdef.
2107 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2108 throughout, to avoid throwing away buffered input from the board.
2109 (nindy_wait): Supply_register takes addr_of_value, not value.
2110 (i960_print_fault): Renamed from i80960_fault.
2111 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2112 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2114 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2115 we can set the PC in the call to proceed(). Unpush nindy_ops
2116 before pushing it on top, to avoid message to user. Eliminate
2117 commentary from Unix machines that just misleads here.
2118 (reset_command): Fix error message to suggest target command.
2120 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2122 Release 3.92.5 as frozen.
2124 Stabilize the merged release...with help from lint, Saber C,
2127 Everywhere: Add include files needed to declare return types
2128 of functions called.
2130 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2132 * breakpoint.h: Add undeclared breakpoint functions, and some
2133 functions for display handling since I couldn't think of a better
2136 * breakpoint.c (insert_breakpoints): Make code for disabling
2137 shared library bkpts more likely to work. It's used when we
2138 rerun a program and stop before the shared library has been
2140 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2141 cast from pointer, so it squeezes through catch_errors.
2142 (bpstat_stop_status): Fix logic broken some time ago. We now
2143 always create a bpstat if the stop address matches a breakpoint,
2144 even if we don't stop there -- just like the old code used to do
2145 before I got my fingers into it (sigh).
2146 (breakpoint_1): Print "ignore count" after "stop only if"
2147 condition, since that's how it actually works.
2148 (mention): Handle watchpoints as well as breakpoints.
2149 (watch_command): use set_raw_breakpoint and mention to do most
2150 of the work (and initialize all the fields!). Only pass one
2151 arg to parse_c_expression, since that's all it takes.
2153 * command.c (not_just_help_class_command): Rename arg to args
2154 since we ignore "unused argument" warnings on vars named "args".
2155 inflow.c (child_terminal_info): ditto.
2156 infptrace.c (kill_inferior): ditto
2157 main.c (catch_errors, version_info, quit_command, pwd_command,
2158 source_command, dump_me_command, editing_info,
2159 set_history_size_command, set_history, show_history,
2161 stack.c (locals_info): ditto
2162 target.c (target_files_info): ditto
2163 valprint.c (set_input_radix, set_output_radix): ditto
2165 * core.c: Remove old variables for handling core and exec file
2166 sections (data_start, data_end, stack_start, stack_end,
2167 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2168 text_end, exec_data_start, exec_data_end, text_offset,
2169 exec_data_offset, data_offset, stack_offset). They're
2170 superseded the more general build_section_table and
2172 (get_exec_file): Mention the `file' command.
2173 (read_memory_check): Rename to memory_error, and only call it
2174 in the case of an actual error.
2175 (read_memory, write_memory): call memory_error.
2176 (core_fetch_registers): Register section name is ".reg".
2178 coredep.c: Remove a bunch of crud now that all this file does
2179 is pull the registers out of a core file.
2180 (fetch_core_registers): Rewrite to actually work, I hope.
2182 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2183 Replace index() with strchr(). Remove all the pre-BFD macro
2184 definitions for accessing the symbol file.
2185 (struct dbx_symfile_info): Encapsulate the information that
2186 dbx_symfile_init needs to pass to dbx_symfile_read in this
2189 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2190 dbx_symfile_discard): Rearrange symbol file reading to divide
2191 the format-specific part from the format-independent part,
2192 leaving the format-independent part such as file name expansion
2193 and opening in symtab.c. This replaces
2194 partial_symbol_file_open and partial_symbol_file_read.
2195 Symbol_file_read, add_file, add_file_target_command,
2196 add_file_addr_command move to symtab.c. Pass an explicit
2197 "mainline" flag for when reading the main symbol table, rather
2198 than relying on the offset address to be zero or nonzero.
2200 (dbx_symfile_read): Don't allow void *'s to be printed as
2202 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2203 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2204 macro" debug version really work.
2205 (read_dbx_symtab): Remove unref'd parameter inclink.
2206 Avoid swapping N_SLINE symbols, for speed.
2207 Merge N_TEXT!N_EXT case with the other external symbol
2208 definitions' case. Add comments.
2209 (start_psymtab): Allocate the symfile name in the psymtab on
2210 the psymbol_obstack, rather than using the caller's storage.
2211 (end_psymtab): Only allocate a dependencies list if there are
2213 (psymtab_to_symtab_2): Use BFD when reopening file to read
2214 its symbols for real.
2215 (read_struct_type): Add FIXME comments where it needs work
2217 (read_huge_number): Add FIXME about overflows.
2218 (read_range_type): Add FIXME about comparing a long to 1<<32.
2220 * coffread.c: Minor changes to move things closer to the new
2221 regime with symtab.c and dbxread.c Major work is still needed
2224 * exec.c (exec_file_command): Remove old variables (see core.c
2226 (xfer_memory): If memory transfer is right at the end of a
2227 section, don't lose.
2229 * findvar.c (get_saved_register): If value is in a real
2230 register, LVAL is lval_register, not lval_memory.
2232 frame.h: Declare print_sel_frame and record_selected_frame.
2234 gdb-int.texinfo: New file, for GDB internals documentation.
2235 Very simple, unformatted doc of cleanups is there for now.
2237 gdbcore.h: Remove obsolete variables that described a.out
2238 section addresses and offsets. (See core.c above.)
2239 Declare fetch_core_registers and registers_fetched.
2241 getopt.c: Declare char *alloca(); even on SPARC.
2243 infcmd.c (run_command): Call target_kill rather than
2245 (step_command, next_command, stepi_command, nexti_command):
2246 Declare from_tty parameter even though we don't use it.
2247 (run_stack_dummy): argument BUFFER is a char array, not
2248 a pointer to REGISTER_TYPE.
2249 (finish_command): using_struct_return needed a value *,
2250 not a struct symbol *.
2252 * infptrace.c (child_xfer_memory): To avoid dependency on
2253 where sections are in memory, try PT_WRITE_D and if that fails,
2254 try PT_WRITE_I. Most Unixes don't care which you use.
2256 * infrun.c (step_resume_break_shadow): Change to array to
2257 match other breakpoint shadow storage.
2258 (clear_proceed_status): Pass address of bpstat to
2259 bpstat_clear, not the bpstat itself.
2260 (child_create_inferior): FIXME comment about if the child
2262 (start_inferior): Remove old function.
2263 (child_open): Use target_kill rather than kill_inferior.
2264 (wait_for_inferior): Ditto.
2265 (insert_step_breakpoint, remote_step_breakpoint): Use
2266 new step_resume_break_shadow.
2268 * inftarg.c (child_wait): If all child processes die,
2269 pretend that the one being waited for exited with signal 42.
2271 * main.c (command_line_input): When scanning for comments,
2272 don't coredump on unclosed quotes.
2273 (quit_command): Use target_kill rther than kill_inferior.
2274 (_initialize_main): Rename class_user from "user" to
2277 * printcmd.c (print_command_1): Initialize "fmt" if no format
2278 is specified by the user.
2279 (print_frame_args): Only add to args_printed if we are
2280 actually fetching args from the stack (avoiding undefined
2282 (_initialize_printcmd): Remove bogus \{ from string.
2284 * remote-eb.c (eb_open): Avoid coredump on no argument.
2286 * remote-nindy.c: Bring out of Intel environment into new
2287 target environment. Remove all conditional compilation on
2288 I80960. Massive hacking throughout.
2289 (nindy_xfer_inferior_memory): New routine stolen from
2291 (nindy_create_inferior): New routine pieced together, probably
2292 not quite working yet.
2293 (nindy_ops): New target_ops struct for nindy.
2295 * remote-vx.c: Use write_memory rather than target_write_memory
2296 to get error checking.
2297 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2299 (vx_create_inferior): Use target_terminal_ours...
2301 * signame.c (_initialize_signame): Always initialize, since
2302 we need the table for things other than psignal.
2304 * solib.c (solib_add): Use symbol_file_add, not add_file.
2305 (solib_address): Return boolean result rather than struct
2306 pointer which nobody else knows the type of.
2308 * sparc-tdep.c, valops.c: Use write_memory rather than
2309 target_write_memory, to get error checking.
2311 * stack.c (locals_info, catch_info, args_info,
2312 get_selected_block, frame_command, up_command): Use
2313 target_has_stack, rather than have_inferior_p or
2316 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2318 * symfile.h: New file, defining the interface between the
2319 generic and object-file-specific symbol reading code.
2321 * symtab.c: Move generic symbol-reading interface to symtab.c,
2322 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2323 table to map BFD targets to symbol-reading modules in GDB.
2324 Change index to strchr.
2325 (lookup_struct_elt_type): Use error() rather than hand-made
2326 simulations thereof.
2327 (lookup_partial_symbol): Speedup slightly when length == 0.
2328 (symbol_file_add): New function.
2329 (symbol_file_command): Call it.
2330 (symfile_open, symfile_init): New function.
2331 (add_file_target_command, add_file_addr_command): moved from
2334 * target.c (target_command): use target_kill.
2336 * target.h (target_files_info): Don't declare, never called
2339 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2340 files to determine stack end address.
2342 * valarith.c (value_x_binop, value_x_unop): Change error message
2343 to be more useful. Pass proper argument to value_struct_elt.
2345 * valops.c (value_assign): FIXME comment that long long
2346 bitfields will break here.
2348 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2349 Update `make saber_gdb' to work better.
2351 * TODO: A woman's work is never done.
2353 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2354 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2355 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2356 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2357 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2358 valops.c, valprint.c, exec.c: Lint.
2361 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2363 Continuing Intel 960 port merge of GDB.
2365 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2366 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2367 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2368 Wack over "make depend" so it handles files in subdirectories
2369 vx-share, nindy-share, bfd, and in the current directory.
2371 * blockframe.c (get_prev_frame_info): Remove fatal error
2372 if stack not defined.
2374 * core.c (core_open, core_detach): New functions that handle
2375 the old "core-file" command as "target core" and "detach" instead.
2376 (core_file_command): Call them.
2377 (core_xfer_memory): Use common routine xfer_memory.
2379 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2380 dbxread now uses bfd for everything but symbol reading itself.
2381 BFD internals are used to drag out the relevant file offsets.
2382 (partial_symbol_file_open): Change args all around for BFD.
2384 * symtab.c: Rename "value" to "val" everywhere, so we can
2386 (symbol_file_command): New command, moved from dbxread.c
2387 and coffread.c. It uses BFD to read the file, then vectors
2388 based on its type, to dbx or coff symbol readers.
2389 * symtab.h: Extern a few vars for symbol_file_command.
2391 * target.h: Breakpoint takes a char * save area, not a char **.
2393 * valprint.c (val_print): When unpacking bitfields, offset
2394 the address in gdb of the value, if it is declared with a shorter
2395 type. Remove the last "runtime kludge test" of host byte order.
2397 * utils.c: Remove old my_bfd_read routine.
2399 * stack.c (frame_info): Use target_has_stack. Print program counter
2400 register's actual name rather than "pc", since it's called the
2401 "ip" (instruction pointer) on the i960 (sigh).
2403 * target.c (target_command): Add command for selecting a target
2404 type and calling its open routine. This is used for initiating
2405 communication with a particular target, in a generic way.
2407 * tm-i960.h: Update for modern gdb. Remove semicolons from
2408 various macros. Handle reading struct return convention, and
2409 error-out attempts to return structs with the "return" command.
2410 Be sure gdb doesn't think we know how to call functions in the
2413 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2414 to i960_xxx in lower case.
2415 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2416 not being defined yet.
2418 * remote.c (remote_open): Call start_remote to initialize
2419 wait_for_inferior during open.
2420 (remote_xfer_inferior_memory): Return length written rather
2423 * remote-vx.c (target_command -> vx_open): Use new generic
2425 * remote-eb.c, inftarg.c, exec.c: ditto.
2427 * infrun.c: Fix comments.
2428 (attach_program -> child_open): Use new generic target command.
2429 (wait_for_inferior): Clear saved register values before target_wait,
2430 so target_wait can set some of them if convenient.
2432 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2433 Return success indicator, not void.
2434 (child_xfer_memory): Avoid fetching initial word if we'll
2435 overwrite it anyway.
2437 * infcmd.c (attach_command): Use new generic target open routine.
2438 (_initialize_infcmd): Update doc on attach and detach commands.
2439 (do_registers_info): Merge in a byte-order problem as a FIXME
2442 * findvar.c (find_saved_register): Avoid problem in current frame.
2443 (read_relative_register): Ditto.
2444 (write_register): Convert byte order on the way out.
2446 * exec.c (file_command): Add.
2447 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
2448 (xfer_memory): Common function between core_xfer_memory and
2450 (exec_xfer_memory): Use it.
2452 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
2454 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
2455 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
2456 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
2458 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
2460 Merge Intel 960 port of gdb, continuing...
2462 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
2463 symbol_file_command): Pass from_tty arg to hush 'em up.
2465 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
2466 Add magic numbers for 960 COFF format.
2468 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)

2476 Remove temp file if download is interrupted.
2478 Wed Aug 1 09:08:33 PDT 1990
2479 Now uses binary protocol to talk to NINDY.
2480 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
2481 Times out after 5 seconds when trying to talk to NINDY.
2483 Tue May 29 12:54:49 PDT 1990
2484 Added variable baud rate (-b switch).
2485 Source code reorganization.
2487 Thu Apr 26 11:09:55 PDT 1990
2488 More cleanup of batch mode; specifically, execute "-s", "-e", and

2491 Fri Apr 20 13:47:15 PDT 1990
2494 Thu Apr 19 09:54:28 PDT 1990
2495 Add 'reset' command.
2497 Wed Apr 18 09:48:07 PDT 1990
2498 After opening remote tty, wait for 1 second to go by without input
2499 from it before trying to talk to NINDY (fixes problems with the
2500 Heurikon HK80/V960E).
2502 Mon Apr 4 16:33:05 PDT 1990
2503 Some output was not being suppressed in 'batch' mode.
2505 Thu Mar 22 15:31:11 PST 1990
2506 Ask user if old symbol table should be deleted when new file is
2509 Allow user to run a program downloaded before gdb960 was brought up.

2536 Mon Oct 2 15:56:31 PDT 1989
2538 Added 960CA disassembly support.
2540 To simplify maintenance:
2541 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
2543 - eliminated opcode.h: incorporates tables into i960-pinsn.c
2544 - moved 960-specific routines from i960-pinsn.c to i960-md.c
2545 - made disassembly interface identical to that in gdmp960.
2549 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
2551 * target.h: Allow targets to stack. Add target_has_memory,
2552 _registers, etc. Restructure memory access and "info files"
2553 to walk the target stack.
2554 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
2555 target.c: Change tables to match target.h.
2556 * inflow.c (child_mourn_inferior): pop child_ops.
2557 (generic_mourn_inferior): Use new has_stack flag.
2558 * infptrace.c (child_xfer_memory): New memory regime.
2559 * inftarg.c (child_files_info): New "info files" regime.
2560 * remote-eb.c: New memory regime, new info files.
2561 * remote-vx.c: New memory regime, new info files. Now use
2562 separate targets for VxWorks attachment to machine, and
2563 actually running a process under VxWorks, since one has
2564 stack & execution & regs and the other doesn't.
2565 * remote.c: New memory regime, new info files.
2566 * sparc-xdep.c (fetch_core-registers): New memory regime.
2567 * target.c: New routines and support for stacked targets,
2568 new memory regime, new info files regime.
2571 Generalize section handling for an arbitrary number of sections,
2572 including use of the new BFD (binary file) library.
2573 * gdbcore.h: Add struct section_table.
2574 * exec.c (build_section_table): Iterate all sections and
2575 record what gdb needs to know about them.
2576 (exec_command): Use it.
2577 (exec_xfer_memory): Use the table.
2578 (exec_files_info): Print the table.
2579 * core.c (core_file_command, core_xfer_memory, core_files_info):
2581 * source.c (find_source_lines): Use bfd_get_mtime.
2582 * dbxread.c: Quick changes to make it compile with new BFD.
2583 * utils.c (error): Avoid using bfd_error in generic routines.
2585 * core.c (core_fetch_registers): Get from the ".regs" section of
2587 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
2589 * inferior.h (attach_flag): Export.
2590 * infcmd.c (run_command): use new target_create_inferior.
2591 * infrun.c (child_create_inferior): Don't return result.
2592 * Makefile.dist (VERSION): 3.91.4.
2594 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
2596 * breakpoint.c (bpstat_num): Handle breakpoints which have
2597 since been deleted, such as temporary breakpoints.
2598 infcmd.c (program_info): ditto.
2600 * core.c (core_file_command): Display the frame where the core
2605 * remote-vx.c (target_command): Merge in target command from
2606 targ-vx.c. A few other cleanups.
2608 * TODO, Projects: Lots more stuff to do...
2610 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
2612 Massive changes to wall off the remote-debugging interface
2613 behind a function vector. The port to handle VxWorks targets
2614 is also part of this.
2616 All files: Replace references to renamed functions,
2617 remove references to remote_debugging, remove references to
2618 have_include_file, have_core_file in favor of target_has_stack,
2619 target_has_memory, etc.
2621 * Modularize the breakpoint interface.
2622 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
2623 a breakpoint instruction.
2624 breakpoint.c: struct breakpoint's shadow_contents now sized as
2626 (insert_breakpoints): Vector to target to install breakpoints.
2627 (remove_breakpoints): Vector to target here too.
2628 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
2629 sparc-tdep.c (single_step): Use new breakpoint interface for
2630 the single-step breakpoints.
2631 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
2632 New file, contains routines to insert and remove breakpoints by
2633 reading out the old contents and later replacing them. This is
2634 how ptrace breakpoints work, and many remote systems as well.
2636 * tm-vxworks68.h: New config file, overrides a few things for
2637 Wind River's preferences.
2639 * target.h: New file, for transfer vector used to talk to the
2640 inferior (child, attached, core, exec, remote, etc). All accesses
2641 to the thing being debugged should come through these vectors.
2642 target.c: New file, routines to handle transfer vector.
2643 (various files): Add transfer vectors XXX_ops for the various
2644 targets and pseudo-targets (core files, etc) we support.
2646 * breakpoint.c (bpstat_stop_status): Further explorations of
2647 watchpoints and why things don't work all the time.
2648 (bpstat_alloc): New fn to allocate a bpstat and chain it.
2650 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
2651 the local gdbinit if it doesn't already have it.
2653 * core.c (core_ops): add and install.
2654 Allow core debugging without exec file.
2656 * dbxread.c (free_and_init_header_files): Merge two fns.
2657 (end_symtab): Free named symbol table when a new version comes in.
2658 (read_dbx_symtab): Relocate all kinds of symbols with base
2659 address. First step toward handling different text, data, bss
2661 (add_file_addr_command): Renamed add_file_command.
2662 (add_file_command): Vector to remote handler.
2663 Add "load" as an alias for "add-file" command.
2665 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
2666 non-returning functions.
2668 * exec.c: Add exec_ops, and push it as a target when an exec
2671 * infcmd.c (run_command): Pass executable file name and arg list
2672 separately when starting an inferior. Permit "run" when no exec
2673 file is specified, for VxWorks.
2674 (detach_command): Move to child_detach in inftarg.c.
2676 * inftarg.c: New file. Unix-child-specific routines, and the
2677 child_ops structure.
2679 * inferior.h (registers): Export "registers" as the way for
2680 target dependent register handlers to find gdb's local copy of
2681 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
2682 since it is now used by places that want wait_for_inferior to
2683 handle the grunge but want to see every trap from the inferior.
2685 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
2686 Eliminate remote_debugging hooks in terminal handling.
2688 * infrun.c: Replace start_inferior with child_create_inferior.
2689 Move all the hair of Unix shells and ptrace idiosyncracies into
2690 child_create_inferior, so remote handlers don't have to deal.
2691 Remove running_in_shell. Rename stop_after_attach to
2692 stop_soon_quietly, and use it in a few other places where we want
2693 to just call wait_for_inferior and get control back on the first
2694 trap. trap_expected now never takes a value > 1.
2695 (init_wait_for_inferior): Initialize static vars when a new
2698 main.c (gdbinit): Add new hook for .gdbinit file name, let
2699 it be overridden by config files as GDBINIT_FILENAME.
2700 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
2701 Both of these are used for VxWorks gdb.
2703 mcheck.c: rename include file "gmalloc.c" to avoid problems
2704 with system include file "malloc.c".
2706 param-no-tm.h: New include file, same as param.h but does not
2707 include the default "tm.h" file. This is used in files where
2708 the target is known, e.g. remote-eb.c or sparc-xdep.c.
2710 param.h: Now just a shell that includes tm.h and param-no-tm.h.
2712 remote-vx.c: New file, VxWorks remote debugging support. Uses
2713 RPC routines that are shared with the target system, in directory
2716 remote.c: Vectorize remote interface.
2718 source.c: Globalize source_path, and make an alias "l" for "list"
2719 since we now have the "load" command.
2721 sparc-xdep.c: Use new param-no-tm.h.
2723 symmisc.c (free_named_symtab): Add new function from Wind River.
2724 However, ifdef it out for now while we think about what it should
2727 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
2729 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
2730 non-Unix-children handle this with their own code in the target
2733 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
2734 source and target lists. Add vx-share to default list of include
2735 directories. Add new files to src and target lists: mem-break,
2736 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
2737 ${srcdir} versions of munch and createtags are used.
2739 * valops.c (find_function_addr): Split out of call_function.
2740 (call_function_by_hand): Rename call_function; this function
2741 calls functions in the target by laboriously patching the target
2742 word-by-word with the right stack, args, regs, etc.
2745 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
2747 Handle AMD 29000 a bit better.
2749 * remote-eb.c (readchar): Mask received char log to make it readable.
2750 (remote_start): Pass arguments down to executing program.
2751 Make startaddr unsigned.
2752 infrun.c (start_inferior): Accept args, pass them to
2754 infcmd.c (run_command): Pass args down to start_inferior.
2756 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
2757 the target object file format.
2758 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
2760 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
2761 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
2763 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
2765 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
2766 * TODO: We did a few things, we have more to do though.
2768 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
2769 * inflow.c (inferior_died): Clear deferred stores.
2771 * Debug problems with dummy frames and calls to the inferior.
2772 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
2773 * sparc-tdep.c (do_restore_insn): Simplify.
2774 (sparc_frame_find_saved_regs): Simplify and fix what we find.
2775 (sparc_push_dummy_frame): Simplify and fix what we push.
2776 (sparc_pop_frame): Slightly more hair here, deciding whether
2777 we are restoring a saved PC or returning to a return address in %i7.
2778 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
2780 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
2781 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
2782 * obstack.h (chunkfun): ditto.
2783 * defs.h (xmalloc, xrealloc): ditto
2785 * utils.c (quit): Grab the terminal from the child if necessary.
2787 * inflow.c (term_status_command): Rename to term_info, change
2790 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
2791 (is_delayed_branch): Speed up.
2792 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
2793 Still missing some float ops, and needs testing.
2795 * Support for input and output radixes other than base 10
2796 * defs.h (input_radix, output_radix): Declare.
2797 * expread.y (yyparse, parse_number): Handle changes of input
2798 radix, and ambiguous names-or-numbers in radixes >10.
2799 * printcmd.c (print_scalar_formatted): Print formatted hex
2800 numbers in varying column widths.
2801 * valprint.c (val_print): Use output_format to print scalar ints.
2802 (set_input_radix, set_output_radix, set_radix): Create.
2803 (set_output_radix): Set output_format from output_radix.
2804 (_initialize_valprint): add `set radix' but leave the others off.
2806 * main.c (execute_command): Let stupid questions be turned off.
2807 (_initialize_main): Handle "set stupidity", etc.
2809 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
2810 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
2812 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
2814 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
2815 bfd stuff is still screwed up, but with some manual work, it
2818 * breakpoint.c (bpstat_do_actions): Start over if a command
2819 proceeds the inferior, since the inferior will have stopped and
2820 will need to have its new stop-actions taken care of.
2822 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
2823 compiler fits, simplify it.
2825 * gdb.texinfo (directory command): Doc new dir command.
2826 source.c (directory_command): "dir" now puts things on the front
2827 of the path, moves dups up front, and handles multiple names
2828 on the command line, inserting each one in order. It also
2829 blows away cached line and full_filename info.
2831 * stack.c (backtrace_command): Skip "more stack frames follow"
2834 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
2835 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
2836 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
2837 The only odd one was Gould NP1, which had defined vprintf to
2840 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
2841 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
2842 variable, inspect_it.
2843 valprint.c (print_string, val_print): Use the global inspect_it
2844 to indicate whether to print in Epoch style or normal style.
2846 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
2848 * printcmd.c (call_command): add an alias for the "print" command
2849 which runs expressions and doesn't print the result if void.
2850 (print_command_1): implement it.
2852 * command.c: Remove #if 0'd code. Initialize all the fields
2853 in add_cmd (). Rename do_nothing_command to
2854 not_just_help_class_command, and make it externally visible.
2855 command.h: add user_commands to struct.
2856 * main.c (define_command): Don't overload c->function with a char
2857 string as well as a function pointer.
2859 * eval.c (evaluate_subexp): Reinstall tiemann changes to
2860 calling convention of value_struct_elt () that got dropped in
2863 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
2864 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
2866 * tm-sparc.h (POP_FRAME): replace some constants with defines.
2868 * sparc-xdep.c (store_inferior_registers): defer stores to regs
2869 until a good time (e.g. when we are about to run the child),
2870 saving ptrace calls.
2871 * infrun.c (proceed): handle DO_DEFERRED_STORES.
2872 * tm-sparc.h: define DO_DEFERRED_STORES.
2874 * sparc-xdep.c (store_inferior_registers): when storing float
2875 registers, don't store stack regs too. When storing the SP,
2876 however, DO store the stack regs too. This fixes a bug in which
2877 the dummy frame is not recognized when a call_function finishes,
2878 because its frame pointer (in the stack regs) was never
2880 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
2881 even though we don't know how to read them from an inferior.
2882 valops.c (call_function): Comment about storing SP.
2884 * infrun.c (save_inferior_status): Save away the original bpstat
2885 chain so it can be restored later. Install the copied version for
2886 use by whoever saved the status. It will be blow away by
2887 restore_inferior_status, and the original chain restored. This is
2888 important for people who have pointers into the original.
2890 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
2891 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
2892 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
2895 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
2897 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
2898 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
2899 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
2901 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
2903 * Merge Mike Tiemann's multiple inheritance changes from Sun.
2904 Store the baseclasses in a type struct starting from array element
2905 0 rather than from the unusual array element 1.
2907 dbxread.c: the above.
2908 (virtual_context): Add
2909 Read new debug information about which virtual function table
2910 a virtual function is from, and store it in fn_field.fcontext.
2912 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
2913 TYPE_FN_FIELD_STATIC_P.
2915 symtab.c: the above.
2916 valops.c: the above. Handle pointer casts of object *'s.
2917 (search_struct_method): Add.
2918 (value_struct_elt): First arg is now a pointer to a value, and is
2921 valprint.c: the above.
2922 values.c (value_virtual_fn_field): Add type arg. Handle
2923 offsetting to the proper object when calling virtual fns.
2925 (baseclass_addr): Add valuep arg.
2927 * README: Document the current state of BFD config (missing).
2928 * TODO, ChangeLog, Makefile.dist: Roll version.
2929 * WHATS.NEW: Add summary of changes since 3.5.
2931 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
2933 * dbxread.c (read_struct_type): Clear bit vectors whenever
2935 symtab.c (B_CLRALL): define.
2937 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
2938 using == rather than =. Huh... This fixes the dreaded problem
2939 wherein builtin_type_int becomes TYPE_CODE_FLT.
2941 * core.c (info_files): Show the inferior pid.
2943 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
2944 already knows how to look in the source directory.
2946 * Remove psymtab hair from many places. Remove duplicated code
2947 for searching symbol tables. Hide psymtabs from most places.
2948 Make it fast to get from a psymtab to its symtab.
2950 blockframe.c (blockvector_for_pc): Remove psymtab hair.
2951 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2952 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2953 dbxread.c: export psymtab_to_symtab, make it work if called N times.
2954 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
2955 new symtab completely. New psymtabs get symtab pointer
2956 initialized to zero. Remove MI warning printf.
2957 symtab.h: Comments. Add psymtab to symtab pointer.
2958 (PSYMTAB_TO_SYMTAB): New macro.
2959 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
2960 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
2962 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
2964 (print_frame_info): Avoid special-casing symbols that have not yet
2967 * source.c (open_source_file): Quick path if we have already
2968 located the source file by its full name.
2970 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
2971 find_pc_psymtab. When a name is found in the misc function
2972 vector, search the symbol table for its mangled name, not the
2973 name that the user typed.
2975 * bfd.h: Fix missing comment terminators, make #endifs match.
2977 * valarith.c (value_less): Handle unsigned int comparisons.
2978 Add FIXME about pointer compares, which assume host and target
2979 pointers are the same.
2981 * command.c (do_nothing_command): lint
2982 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
2983 fix comments on debug symbol format for visibility. Actually set
2984 visibility of symbols.
2985 main.c (echo_command): lint; use <readline/history.h>.
2986 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
2987 obstack.h (_obstack_blank): Rearrange pointer math to avoid
2988 pointing past end of allocated memory; saber complains.
2989 obstack.h: Declare the external functions that we use.
2990 valarith.h: use <string.h>
2991 solib.c (solib_add): lint.
2993 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
2995 * main.c (initialize_main): Default info_verbose to off, now that
2996 symbol reading is fast.
2997 (quit_command): Avoid clobbering exec_bfd while quitting.
2999 * Initial BFD (binary file diddling library) merger:
3000 coffread.c: Change AOUTHDR to struct exe_hdr.
3002 core.c: initialize initialized data at compile time.
3003 (core_file_command): Move from coredep.c, convert to bfd.
3004 (xfer_core_file): Convert to bfd.
3005 exec.c (exec_file_command): use bfd routines.
3007 mips-tdep.c: Remove exec_file_command and friends.
3010 * coredep.c: (fetch_core_registers) Convert core_file_command to
3011 fetch_core_registers.
3012 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3014 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3015 (my_bfd_read): More bogosity, which I don't think we call.
3016 (program_name): Remove this atrocity asap!
3018 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3021 values.c: allocate_repeat_value was not clearing the
3022 optimized_out field.
3023 (value_static_field): minor stylistic fix (wrong macro was used).
3024 valops.c (value_struct_elt_for_address): didn't work for C++
3027 * signame.c (_initialize_signame): Initialize signal names once.
3029 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3030 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3031 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3033 * remote-eb.c: Support user-settable baud rates on the serial port.
3035 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3037 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3039 * tconfig/sun3os4: Remove warning about native assembler,
3040 since it also occurs in the xconfig file.
3042 * findvar.c (registers): Allocate some slop after `registers'
3043 to prevent stray accesses from trashing the next variable.
3045 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3046 on the sun-3, by changing the #ifdef from `sun3' (which is not
3047 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3048 vars, which happened to follow `registers' in the executable.
3050 * readline/history.c (history_search): Heed gcc-2's advice
3051 and parenthesize && inside ||).
3053 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3054 tm-29k.c: Insert FSF copyright headers.
3056 * remote-eb.c: Better comments.
3058 * Makefile.dist: Update to 3.91.6.
3059 * TODO: note PREPARE_TO_STORE problem.
3061 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3063 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3065 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3067 * infrun.c (wait_for_inferior, at end): Don't set up
3068 prev_* if the inferior no longer exists.
3070 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3071 CANNOT_EXECUTE_STACK.
3072 valops.c (call_function): Use it.
3074 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3076 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3077 infrun.c (wait_for_inferior, 2 places): Use it.
3079 * values.c (value_being_returned): Only use
3080 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3082 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3083 right thing for remote-eb.c.
3085 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3086 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3088 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3089 (FRAME_FIND_SAVED_REGS).
3091 * findvar.c ({fetch,store}_registers): Check for
3092 REMOTE_{FETCH_STORE}_REGISTER macro.
3094 * findvar.c (get_saved_register): Add argument lval and
3095 change meaning of argument addr.
3096 findvar.c: Change calls to get_saved_register to reflect
3097 new calling convention.
3098 valops.c (value_assign): Use get_saved_register instead of
3099 find_saved_register.
3101 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3103 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3104 an (uninitialized) pointer to one. Use "&" when passing it
3107 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3109 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3112 * coffread.c (symbol_file_command): Put semicolon after
3114 Put safe_to_init_tdesc_context in #if defined (TDESC).
3115 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3116 coffread.c: #include <sys/stat.h>.
3117 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3118 Add missing ')' in check for "lc%" and friends. Remove
3120 Declare read_one_sym() at top of file.
3121 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3122 MC68WRMAGIC can have the same value without causing a duplicate
3125 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3127 * Allow a Makefile to be built without building the
3128 tm and xm file links that screw up builds in subdirectories.
3129 This is done with `config.gdb none', then you can do things
3130 like `make gdb.tar.Z'.
3131 * tconfig/none: Config file for no target system
3132 * xconfig/none: Config file for no host system
3133 * config.gdb: If no TM or XM files are called out by the
3134 host or target file, don't make links for them.
3136 * cplus-dem.c: Add documentation.
3138 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3139 simple error, so the user's gdb doesn't crash due to some object
3140 file problem (e.g. somebody is rebuilding the file out from under
3143 * printcmd.c (print_address_symbolic): demangle the symbol.
3145 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3146 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3147 (alldeps.mak): sort and uniq all results from this; duplicates
3148 hose gdb.tar.Z link building. Remove RCS files from
3149 tconfig and xconfig. Add config files for sun386. Add
3150 a few odd files to OTHERS and HFILES.
3152 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3154 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3155 Roll version number to 3.91.5. Make lint work in bindir.
3157 * README: Document cross-debugging and new file structure.
3159 * blockframe.c: Lint. Include "value.h" to declare read_register.
3160 (find_pc_partial_function): remove duplicate line.
3162 * command.h: Lint. Declare error_no_arg and dont_repeat.
3164 * tm-news.h: Remove inadvertently duplicated stuff.
3166 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3167 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3169 * config.gdb: Allow `config.gdb host target' form. Clean
3170 up previous change that printed bogus messages when you just said
3173 * core.c: #include "command.h" for lint.
3176 * main.c: Remove some casts of enums. Lint.
3183 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3185 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3186 read it from memory. This will allow us to save ptrace calls
3187 eventually. Changed caller single_step too.
3189 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3190 that we aren't going to use, saving many ptrace calls, especially
3191 when watchpointing or single stepping. Use some #define's for
3193 (store_inferior_registers): Ditto.
3194 (core_file_command): Use some #define's for constants.
3196 * tm-sparc.h: Add #define's for some register numbers, so we
3197 can eliminate the use of random constants in sparc-xdep.c.
3199 * stack.c (frame_command, print_frame_info, up_command,
3200 down_command) Remove frame_changed, since it
3201 causes a bug and doesn't seem to do anything useful. In some
3202 places it was used as a flag, in others as a stack level (?).
3204 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3205 default is to use the portable (vprintf) version rather than the
3207 * xm-news.h (MISSING_VPRINTF): Add.
3209 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3211 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3213 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3214 about linking debugged programs -Bstatic in the sun?os4 config
3215 files in tconfig and xconfig subdirectories.
3217 * main.c (main): Remove unreached exit(0) now that we exit
3220 * Create TODO file for online bug list. There are too many
3221 "little" bugs to keep track of on paper.
3223 * Change Projects file to refer to bug-gdb@cygnus.com
3224 rather than kingdon@ai.
3226 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3228 * Makefile.dist (VERSION): 3.91.4 now.
3230 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3231 (condense_misc_bunches): Add sanity check that misc_count is
3232 the same as the number of symbols in the bunch.
3234 * coffread.c: rename init_misc_bunches. Pass an argument
3235 to condense_misc_bunches (a zero).
3237 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3238 every time we are called; don't rely on our caller to do it.
3239 (add_file): Remove call to init_misc_bunches.
3241 * mipsread.c: Only warn, don't error, if unknown symbol types.
3242 This keeps an old gdb from falling on its face if it sees newly
3243 extended symbol info. Rename init_misc_bunches.
3245 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3247 * Merge in changes from Per Bothner for DECstations and other
3248 MIPS stuff. The rest is Bothner speaking:
3250 The next message is a merger of Alessando Forin's mips port with
3251 mine. I've tried to use my good if biased judgment to get
3252 the best of both. It *does* need testing.
3254 Some of the changes are general, *not* mips-specific.
3257 Didn't believe in little-endian bit order.
3258 There are still inconsistencies about whether flags
3259 like BITS_BIG_ENDIAN are integer (#if ...) or
3260 boolean (#ifdef ...). I tried to paper over them.
3262 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3263 Moved some misc_function code that was common to
3264 {dbx,coff,mips}read.c to symtab.c.
3265 In the process, I think I cleaned things up a bit.
3266 At the same time, moved obsavestring and obconcat to symtab.c.
3269 Removed obsolete condense_addl_misc_bunches (use
3270 condense_misc_bunches(1) instead).
3273 Needed to include <sys/dir>, at least on DECstations.
3275 valops.c, mips-tdep.c, tm-mips.h:
3276 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3277 conventions (when STACK_ALIGN is insufficient).
3278 Needed on mips, where doubles need 8-byte alignment,
3279 but ints only need 4.
3282 Removed cruft that was not being used.
3283 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3286 Print $ before register-names (I think that makes things a little
3288 Never print two instructions, even if one delays.
3289 Removed hex-disassemble set_cmd. (This is not mips-specific,
3290 so I think the argument is whether it is generally worthwhile or not.
3291 I'm inclined to think not, given how easy it is to
3292 convert between radixes in gdb.)
3295 This is basically Alessando's code.
3296 It doesn't use obstacks; I changed it to use obstacks
3297 in a few minor places where using malloc causes a
3298 memory leak. (Probably, more places could/should be changed.)
3299 I added record_misc_function where it was missing.
3300 In symbol_file_command and add_file_command, I tried
3301 to make the code consistent with more recent versions.
3302 Minor sylistic changes in parse_procedure.
3303 Make a .gdbinfo. psuedo-symbol point back to the real
3304 procedure symbol (using the isym field).
3307 This is basically from my port, but with a lot of details
3308 and a number of routines merged in from Alessando's version.
3309 I basically used my code "raw" backtrace (use heuristics
3310 from the actual code, rather than symbol table info) - though
3311 the idea is Alessandro's. I feel my code is a little cleaner
3312 here, particularly in being a little more flexible, such as being
3313 able to handle gcc-produced code (which it now can).
3314 It also doesn't do frame caching (which is not useful
3315 more recent gdb versions).
3316 I also used my code for push_/pop_dummy, more or less.
3317 I tried to incorporate AF's code for testing sigtramp
3318 while backtracing; I probably got it wrong.
3319 Added mips_print_register, which tries to scrunch as much
3320 information as possible on a screen...
3321 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3322 under mips-pinsn.c), I don't see anything mips-specific here,
3323 and I don't see it being all that useful anyway.
3326 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3327 Use more register names (rather than hard-cases numbers).
3329 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3331 * Hack up 3.90.11 changes:
3333 * Makefile.dist (depend): parameterize $(GCC).
3334 Add solib.c and solib.o.
3335 (readline): Fix vpath for both absolute or relative SRCDIR.
3337 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3338 Also, let the part I didn't understand at least compile so
3339 I can test the rest. FIXME.
3341 * dbxread.c: Fix thinko using strcmp.
3342 (init_psymbol_list): declare static.
3343 (partial_symbol_file_open): Comment cleanups better, avoid
3344 cleaning up the string table since the caller will do that.
3345 Move the stat for mod time into symbol_file_command, temporarily.
3346 (There should be a mod time for each symbol file, eventually,
3347 to control its rereading. FIXME.)
3349 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3350 SunOS, which gives error for shared libs otherwise. (From
3351 Schaefer, probably FIXME needs work for portability.)
3353 * solib.c: Move #include "param.h" to work.
3354 Lowercase all the Uppercase Letters In the Messages.
3355 (find_solib): Clean up inferior_so_name for debug printouts.
3356 Allow no argument, to mean all shared libraries.
3358 * symmisc.c: include param.h to get CLEAR_SOLIB.
3360 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3362 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
3363 to 3.90.11. ChangeLog entries below are from this.
3365 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)

3371 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3375 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
3377 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)

3381 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3383 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
3384 Put parens around gcc_p in expansion.
3386 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3388 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
3390 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3392 * Changes for Sun shared libraries:
3393 blockframe.c (find_pc_partial_function): If a non-text symbol
3394 is found, set *address = pc - FUNCTION_START_OFFSET.
3395 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
3396 Disable breakpoints instead of giving an error.
3397 source.c (select_source_symtab): Initialize cs_pst.
3398 symmisc.c: Call CLEAR_SOLIB if defined.
3399 symtab.h: Make text{low,high} CORE_ADDR not int.
3400 (psymtab): New field addr.
3402 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
3403 (record_misc_function): Give correct type for N_DATA symbols.
3404 (condense_misc_bunches): do "misc_function_count = j" regardless
3406 Take code which is shared between symbol_file_command and
3407 add_file_command and put it into partial_symbol_file_{open,read}.
3408 Split add_file_command into add_file_command and add_file.
3409 Make psymtab_to_symtab read in the string table if the file
3411 Two new parameters to read_dbx_symtab and start_psymtab.
3412 tm-sunos.h: New file.
3414 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3416 * infcmd.c: Change cont_command to continue_command and "cont"
3419 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3421 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
3423 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
3425 * values.c (USE_STRUCT_CONVENTION): Check for structures of
3426 size 1,2,4,8 rather than size < 8.
3428 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
3429 as necessary, not just once.
3431 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3433 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3435 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3437 * tm-news.h: Add CALL_DUMMY_*.
3439 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
3441 * config.gdb: In list_host, list_target, use ${i}, not $i.
3443 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3445 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
3447 * sparc-opcode.h: Change all store floating-point state register
3448 instructions to have the right match & lose fields.
3450 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3452 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
3454 config.gdb: If srcdir != ., create readline directory and
3455 copy a makefile into it.
3457 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
3458 consistency with POSIX.
3460 * breakpoint.c (bpstat_stop_status): Disable watchpoint
3461 when we exit its exp_valid_block.
3463 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
3465 * Makefile.dist: Bump version to 3.91.3.
3467 * Clean up handling of breakpoint commands (somewhat).
3468 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3470 inferior.h: Add breakpoint_proceeded to inferior status struct
3471 and globals; save it and restore it.
3472 (clear_breakpoint_commands): Cleanup, remove old #define.
3474 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3475 (save_inferior_status, restore_inferior_status): handle it also.
3476 (proceed): Remove earlier code that set breakpoint_proceeded.
3477 It is now set only in clear_proceed_status.
3478 (clear_proceed_status): Cleanup, use bpstat_clear rather
3479 than clear_breakpoint_commands. No callers need the stop_bpstat
3480 between clear_proceed_status and proceed.
3482 infcmd.c: Add breakpoint_proceeded definition and comment.
3483 (cont_command, jump_command, signal_command): Move call to
3484 clear_proceed_status right next to call to proceed.
3486 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3487 caller's argument while running down the chain of breakpoints.
3488 Use new variable "breakpoint_proceeded" to determine when
3489 a command that it executes moves the inferior past the
3491 (bpstat_clear): Handle NULL argument.
3492 (bpstat_clear_actions): Avoid useless call to
3493 breakpoint_auto_delete.
3494 (delete_breakpoint): Clean up bpstat's that are pointing to
3495 the deleted breakpoint from the stop_bpstat chain.
3496 (breakpoint_auto_delete): Simplify.
3498 * Clean up handling of EOF, error on stdin, etc. This was
3499 prompted by a network problem that caused gdb to go into an
3500 infinite loop filling up its malloc'd memory.
3502 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
3503 not clear_breakpoints_commands, which is now gone.
3504 (main): If command_loop returns (e.g. from EOF on stdin), do
3505 a quit_command (looping back to command_loop if quit_command
3506 doesn't really quit).
3507 (command_loop): check result from command_line_input and
3508 exit if it returns NULL, rather than passing the NULL to
3510 (gdb_readline): Free malloc'd result space before returning
3513 * utils.c (query): Handle C-d to mean "yes", just as if the
3514 input was not a terminal. Also avoid infinite loop if EOF
3515 occurs in mid-input-line before newline. This allows
3516 query to be used at EOF on stdin with reasonable results.
3518 * infrun.c (proceed): Set breakpoint_proceeded.
3520 * values.c (value_as_long): Avoid infinite recursion for enums.
3521 (_initialize_values): Fix typo in help msg (kingdon).
3523 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
3524 RL_LIB for linking. This allows -lreadline for linking
3525 and nothing for dependencies, once readline is a real library.
3527 * config.gdb: Jim Kingdon: give useful error message if the
3528 host or target type is not recognized.
3530 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
3531 it just defines it. Dumb, but deal with it.
3533 * Jim Kingdon suggests:
3534 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
3536 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
3538 * Makefile.dist (VERSION): Bump version # to 3.91.2.
3540 * Clean up Bothner's changes.
3542 * blockframe.c (clear_pc_function_cache): New function.
3543 * blockframe.c: remake cache_pc_function_* static.
3544 * dbxread.c (symbol_file_command): remove references to
3545 cache_pc_function_* variables.
3546 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
3547 * printcmd.c: Avoid kludging a global variable (addressprint)
3548 to avoid printing the address of a string twice. Instead,
3549 pass the format letter 's' down low enough that it can be seen
3550 to avoid this problem.
3551 (print_formatted): Pass format arg to value_print.
3552 (restore_addressprint): Remove function.
3553 (do_examine): Avoid hacking addressprint, cleanups and such.
3554 (print_frame_args): Add a comment to a Bothner change.
3555 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
3556 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
3557 to wipe out the values cached in blockframe.c.
3558 * symtab.c (find_method): Add comment saying how big you must
3559 allocate to be "big enough". Per being terse again.
3560 * valprint.c (val_print): Handle format letter "s" to print
3561 strings without addresses. Add comment to vtbl printing code
3562 which casts with wild abandon. Rearrange reference-printing
3564 @0xaddr: value (print w/addressprint)
3565 value (print w/~addressprint)
3566 @0xaddr (parameter lists w/addressprint)
3567 or nothing (parameter lists w/o addressprint)
3569 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
3571 * Merge more changes from Per Bothner:
3573 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
3574 annoying) that I tried to improve it. Here are my suggestions.
3576 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
3579 Do automatic de-reference when taking the address of a reference.
3581 Don't deref_ref when printing parameter lists.
3583 More attempts at treating refernences properly.
3585 In val_print, if deref_ref==0, don't print dangling " = ".
3587 Add COERCE_REF macro, which de-references an REF.
3589 * Merge changes from Per Bothner:
3591 * Fixed (Sony news)-specific configuration problems.
3592 * Fixed other problems with using vanilla pcc and libc (enum problems;
3593 assumption that vsprintf exists).
3594 * Some major speed-ups (finc_pc_partial_function now caches a match;
3595 parsing avoids duplicate symbol_lookup calls).
3596 * Changed handling of baseclasses (no longer use baseclasses field
3597 of struct type, use the first n_baseclasses fields instead).
3598 * Various minor changes/fixes, most C++-related.
3601 Cache the most previous match from find_pc_partial_function.
3602 (Save both low and high ends of matching function's pc range.)
3603 This speeds up the loop of infrun.c:wait_for_inferior quite
3604 a bit, and makes step/next commands much zippier.
3606 Added an enum->int cast (otherwise, some compilers barf).
3608 No longer set baseclass offset to 0, since multiple
3609 inheritance now mostly works.
3610 Added a number of casts, to shut up compiler warnings
3611 (after stabs where made enums, not ints).
3612 When discarding a symbol table (in symbol_file_command),
3613 must clear the cache introduced in blockframe.c.
3614 Don't convert $vtbl_ptr_type to vtbl any more.
3615 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
3616 Mask off sign bit emitted by g++ for virtual table offset.
3617 Set voffset to -1 (not 1) for static member functions.
3619 Changed parsing/lexing of names to avoid doing symbol lookup twice
3620 (once when lexing to determine symbol class, once for real).
3621 Now only call symbol_lookup once. Fields of 'this' win especially big.
3623 Subpress printing addr twice in the case of 'x/s addr'.
3625 lookup_basetype_type is no longer used.
3626 Add find_methods as recursive helper function to decode_line_1.
3627 This allows multiple inheritance to work.
3628 Also, once one or more matches has been found, do not look in
3629 base-classes. (Baseclass methods would be overridden, anyway.)
3631 Removed baseclasses array in struct type.
3632 Instead of using baseclasses[i], use fields[i-1].
3633 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
3634 Changed sign convention of voffset (previous was inconsistent).
3636 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
3638 Used to assume existence of vsprintf. Re-written to not need it
3639 if HAVE_VPRINTF is undefined.
3641 typecmp was too pessimistic. Made it less so.
3643 Don't print space after address.
3644 If vtable points to a misc symbol (with 0 offset), print it,
3645 since that indicates the actual class of the object.
3646 Changed ype_print_derivation_info to use new inheritance
3647 scheme (without baseclasses vector).
3649 In value_primitive_field, fixed some bugs left over from previous set of fixes.
3650 Also, changes needed because TYPE_BASECLASSES were removed.
3652 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
3654 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
3657 If there is no path set, and the symbols don't indicate what directory
3658 a file was compiled in, look in the current directory. But either
3659 a path or a known compilation directory will prevent this.
3662 Three independent bug fixes:
3663 * Remove the #if 0 block that breaks some stuff.
3664 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
3665 adapt gdb to either SunOS 4.0.* or 4.1.
3666 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
3669 Instantiate the class T when looking for methods in it. (Tiemann@sun)
3672 (type_print) Demangle the name being printed.
3673 (type_print_base) Handle botched demangling without coredump (tiemann).
3676 (check_stub_method): Document routine.
3677 (tiemann) fix bug for no-arg functions
3678 Avoid clobbering beyond end of malloc'd storage.
3679 Terminate the argument list properly.
3681 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
3683 * Changes merged by John Gilmore:
3686 In breakpoint_1, use new print_address_symbolic instead
3687 of find_pc_partial_function. (This forces use of assembler-level
3688 addresses, and avoids misleading non-mangled source-level names.)
3690 Generalize ansi argument such that -1 means skip arglist totally.
3691 Removed global variable print_ansi_qualifiers (which made
3692 code non-reentrant), in favor of extra explicit arguments
3693 to internal routines.
3695 Add new helper function print_address_symbolic.
3696 Use find_pc_misc_function instead of find_pc_partial_function
3697 (since we want assembler-level symbols here).
3699 Print unknown function as just "f (...)", not "f (...) (...)".
3700 Use new fputs_demangled explicitly.
3702 Fixed a typing violation (problem: value.h cannot be imported
3703 without renaming many variable in this file).
3704 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
3705 decode_line_1: Moved forward some never-reached code.
3706 Made decode_line_2 skip function prologues correctly.
3708 fputs_filtered should not demangle by default.
3709 Add new fputs_demangled to demangle on demand..
3711 Change value_struct_elt to use value_primitive_field (using recursive
3712 utility function search_struct_field). This allows foo.bar to work
3713 for multiple inheritance (so far only for data fields).
3714 Change check_field in the same way (recursive helper function
3715 to support multiple inheritance).
3716 (Note: there are more of these problems that I haven't fixed.
3717 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
3718 value_of_this: 'this' symbol name is now just "this", note "$this".
3720 Don't print static members.
3721 Avoid printing "members of <type>" if there are none.
3722 Simplified type_print_derivation_info by merging duplicate code.
3723 Remove useless blank lines in type_print_base (ptype command).
3725 Added declaration of new routine value_primitive_field.
3727 Added value_primitive_field which is generalized version of
3728 value_field that can handle multiple inheritance (non-zero offsets etc).
3729 Re-implemented value_field to call value_primitive_field.
3731 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
3733 * infcmd.c -- insert else to avoid 'delete env' coredump when you
3734 delete the whole environment. Karl Berry reported the bug.
3735 * source.c - fix openp to avoid //'s in filenames, which
3736 trigger an Emacs bug causing it to not be able to find files
3737 when running gdb in a window.
3738 * dbxread.c - zap the #if 0 that botches the add-file code.
3739 It seems to work a lot better without all the code commented out.
3741 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
3743 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
3746 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
3748 * Makefile - added a ${CFLAGS} to a couple of entries,
3749 added remote-sa.sparc.c
3750 * added remote.sa-sparc.c, a modification of remote.c
3751 which conducts a dialog directly with the SparcStation prom.
3752 * breakpoint.c, infrun.c, sparcdep.c added
3753 remote_insert_breakpoint(), and remote_remove_breakpoint()
3754 to breakpoint.c instead of directly writing breakpoint instructions.
3755 * sparcdep.c on remote_debugging,there is no need
3756 to remove signle step breakpoint instructions.
3757 * main.c added "-epoch" flag and "int epoch_interface" to main.c
3759 * printcmd.c - epoch interface sends lisp expressions to open up
3760 epoch windows on inspection.
3761 * valprint.c - added arrayprint, and addressprint and made adding
3762 format controls easier
3763 * wait.h added a couple of undef's because we were getting
3764 complaints about WSTOPSIG and WTERMSIG begin redefined.
3767 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)

3789 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
3791 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
3792 should print ANSI qualifiers (such as `const' and `volatile').
3793 All callers changed to call with ANSI == 1, except from
3794 `check_method_stub', which uses old-style syntax.
3796 * symseg.h (struct fn_field): Remove unneccessary `args' field.
3797 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
3799 * values.c (check_stub_method): New function.

3816 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
3818 * blockframe.c (blockvector_for_pc): New function.
3819 * blockframe.c (block_for_pc): Changed to call
3820 `blockvector_for_pc' and get the block itself.
3822 * stack.c (catch_info): New function. Prints info about
3823 exceptions which can be caught in the current frame.
3824 * stack.c (print_frame_label_vars): New function. Similar to
3825 `print_frame_local_vars'.
3826 * stack.c (print_block_frame_labels): Prints out labels that are
3827 defined in this frame. These labels are exceptions that can be

3832 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
3834 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
3835 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
3836 when printing the type.
3838 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
3840 * valprint.c (val_print): Use `baseclass_addr' to access the
3841 baseclasses pointed to via the derived class object at VALADDR.
3843 * values.c (baseclass_addr): New function. Casts derived pointers

3851 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3853 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
3854 exp_valid_block field correctly.
3856 * infrun.c (wait_for_inferior): When checking "don't even think
3857 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
3858 also check step_resume_breakpoint.
3859 Insert breakpoints and continue (not step) if
3860 step_resume_break_address != NULL, even if another_trap.
3861 If trap_expected and we enter sigtramp, then set up a
3863 If trap_expected is set when we hit the step_resume_break,
3865 When calling resume and trap_expected says tell resume to step
3866 (2 places), also check step_resume_break_address.

3877 Restore old code which distinguishes between trap_expected and
3878 running_in_shell, just make the latter take any non-TRAP signal,
3881 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
3883 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.

4027 to remote_fetch_registers.
4029 * mips-tdep.c (_initialize_mipsdep): Remove hex_disassembler
4030 and re-write skip_prologue to use add_set_cmd.
