3 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
4 chapter 9; (2) documented 'break' command's menu mode for

10 consistent use of @code, @samp, @file, @kbd throughout; small
11 cleanups to first three nodes; (3) new "Contributors" node;
12 (4) Appendix, Renamed Commands; (5) divert specialized startup
13 instructions to "Targets" chapter for generic manuals, while
14 leaving them up front for manuals specific to specialized
15 environments; (6) apply fixes from RMS comments through chapter 4.
17 * pretex.m4: modify explanatory text slightly (and redefine
18 "regexp") to keep GNU m4 from complaining. (It still crashes

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

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

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

491 before returning locals or slocals.
493 * i386-tdep.c (i386_follow_jump): Do not add data16 to pos in
494 call to codestream_seek; add one to pos if (and only if)
495 we are dealing with a jump with data16 == 1 (i.e. 0x66, 0xe9).

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

539 * coffread.c (read_coff_symtab): Check for "LF%" with all the
542 * coffread.c (SDB_TYPE): New macro.
543 various: Use it instead of checking against T_NULL.
545 * Makefile.dist (cplus-dem.o): Hack in an #include "param.h"
546 before we compile it.
547 defs.h: Protect against multiple inclusion.
548 param.h: Include defs.h.
549 signame.c: Change #ifdef SYS_SIGLIST_MISSING to #if.

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

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

643 command is add-symbols.
644 * target.c (dummy_target): Permit add_syms_addr_command.
646 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
648 Permit symbols to be superseded when new symbol files have
649 been read in, particularly for VxWorks.
651 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
652 to the main file, as well as to include files. Also, put global
653 functions into the global psymtab, to make "i fun" work.
654 (end_psymtab): Free named symtabs and psymtabs for a file, once a
655 new psymtab for it has been read.
656 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
657 a file, once a new symtab has been read for it.
658 * mipsread.c: FIXME. We need to do the same for MIPS, but it
659 looks harder to determine the top-level block before it's been
660 queued to the psymtab list.
662 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
663 If we have wiped out any old symbol tables, clean up at end of
665 (symbol_file_command): Don't reference symfile_fns if it's zero.
667 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
668 defines for the blocks of a blockvector that contain global and
669 file-static symbols and the first of the smaller scope contours.
670 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
671 decode_line_1, make_symbol_completion_list): Use the above.
672 * coffread.c (end_symtab, patch_opaque_types): Ditto.
673 * dbxread.c (end_symtab): Ditto.
674 * expread.y (block): Ditto.
675 * mipsread.c (throughout): Ditto.
676 * symmisc.c (free_named_symtabs): Ditto.
678 * symtab.c (list_symbols): Process the first symbol of the
679 static psymbols list.
680 (types_info): Restore this function from its untimely #if 0.
681 It's not perfect, but it is better than nothing.
682 (_initialize_symtab): Restore "info types".
684 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
686 * m68k-stub.c: Remote stub for 680x0's, created from
687 rem-m68k.shar (which is removed).
688 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
689 Remove RCS log stuff now that we use CVS and it blows our diffs.
691 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
693 * symmisc.c (free_named_symtab): Make it work, in its current
694 kludgy fashion. Change result to indicate if we blew away bkpts.
695 * dbxread.c (end_symtab): Accumulate result from
696 free_named_symtab and print warning if we blew user's state.
697 * symfile.h: free_named_symtab now returns an int.
699 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
701 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
702 is the first symbol read, even if not mainline.
703 (dbx_psymtab_to_symtab): symfile might be zero, cope.
704 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
705 (set_section_command): New command ("section xxx yyy" -- should
706 be renamed to "set section xxx yyy" FIXME) which sets the
707 base address of a section of the exec file, overriding the
708 virtual address that BFD reports.
710 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
712 * exec.c: Add add_syms_addr_command to exec_ops, so you can
713 load symbols at any address while examining an exec file.
715 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
717 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
718 for printing the float info is host-dependent, not
719 target-dependent. FIXME.
720 * i386-pinsn.c: Move #includes to top, remove useless ones.
721 * i386-tdep.c: Don't bother including <.../reg.h> since we
722 don't use it (and it doesn't exist on host systems).
724 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
725 Convert negative numbers properly.
726 (ieee_test): Make numbers really random; fix format arg.
728 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
729 * core.c (core_detach): Unpush core_ops, which might not be on
730 top. We used to just pop the top, which broke things. Don't
731 need dont_repeat() any more.
732 (core_file_command): Psst! Don't repeat it.
733 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
734 * expprint.c (print_subexp): Avoid switch fallthru on
735 BINOP_ASSIGN_MODIFY, so we can print += and such.
737 * inflow.c (kill_command): After killing inferior, print our
738 current frame in the core file, if we have one.
739 (generic_mourn_inferior): When inferior dies, either select
740 the current frame (in the new target, e.g. core file), or
741 set both the current and selected frames to NULL.
743 Changes from Peter Schauer.
745 * infptrace.c: Avoid <sys/ptrace.h> on USG.
747 * Make all file names fit in 14 characters (sigh and damn!):
748 mv hp300hpux-xdep.c hp300ux-xdep.c
749 mv symmetry-xdep.c symm-xdep.c
750 mv symmetry-tdep.c symm-tdep.c
751 mv convex-opcode.h convx-opcode.h
752 mv tm-vxworks960.h tm-vx960.h
753 mv tm-vxworks68.h tm-vx68.h
754 mv Makefile.srcdir Makefile.sdir
755 mv gdb-int.texinfo gdbint.texinfo
756 mv remote-sa.m68k.shar rem-m68k.shar
757 mv remote-multi.shar rem-multi.shar
758 * Makefile.dist, README, config.gdb, convex-pinsn.c,
759 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
760 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
763 * command.c (user_info_1, user_info): New command for listing
764 the user-defined commands.
766 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
768 * dbxread.c (really_free_pendings): Clear file_symbols
769 and global_symbols after freeing them; otherwise, running
770 this function twice (if it appears twice on the cleanup
771 chain), we try to free things twice.
773 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
774 based on text_addr (the address of text in core), not on addr (the
775 offset between text in the .o file and in core). This change
776 is from Peter Schauer.
778 * main.c: Define ALL_CLEANUPS as a cast of zero.
779 (return_to_top_level): Use it.
780 (main): Do all cleanups after each command run as part
781 of the gdb startup sequence. Also do all cleanups before
782 entering the command loop, and every time we exit the command
783 loop and reenter. Before, the cleanups from the startup sequence
784 were being left undone until the first error!
785 (command_loop): Rename do_nothing cleanup to command_loop_marker
786 so we can see it easily when examining the cleanup chain.
787 (init_signals): Add another do_nothing for signal handling.
788 (quit_command): Only try to kill target if it has execution.
789 Problems in the target stack got us into a state where
790 inferior_pid was nonzero but none of the targets had execution.
791 In this state you couldn't exit gdb.
793 * dbxread.c: Two changes from Peter Schauer.
794 (echo_command): Fflush output after an echo command.
795 (show_history): Pass all args to cmd_show_list.
797 * utils.c (init_malloc): Call mtrace to turn on tracing
798 if the environment variable MALLOC_TRACE is set to a file name.
799 * mtrace.c: Add source file which provides a log of every malloc,
800 free, and realloc to a trace file.
801 * mtrace.awk: Add source file which analyzes the trace file.
802 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
803 (VERSION): Roll to 3.94.3.
805 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
806 (check_duplicates): Don't bother with watchpoints.
807 (set_raw_breakpoint): Comment about danger of this routine.
808 (watch_command): Parse and eval all args before calling
811 * solib.c (find_solib): Avoid error in referencing memory to
812 see if any more shared libraries have been added. This is
813 particularly useful if the target has terminated. Bug reported
817 in bringing up 3.94.2 on the Sun-3.
819 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
820 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
821 expression (in scope) before reenabling watchpoint.
822 * signame.c (init_sigs): Add missing declaration of i, fix
823 sys_siglist declaration.
824 * source.c (list_command): Fixed range computation to use
826 * stack.c (backtrace_command): Do not allow command if target has
827 no stack, print informative error message.
828 * target.c (target_command): Do not write into command line
829 because this fails if the target command is used in a user defined
830 command. [This change was enhanced by gnu to support any-
831 unique-prefix matching on target names.]
832 * valops.c (value_struct_elt): Avoid infinite loop on an
833 erroneous attempt to print the member of function (try p main.p).
835 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
837 * expread.y (name_no_typename): Avoid reduce/reduce errors
838 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
839 Since the GDB parser really doesn't use name_no_typename in a
840 name-only context, the parser can't tell the diff between
841 names and numbers here. Avoid allowing a name_no_typename
842 to be a NAME_OR_*INT to resolve the conflict.
844 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
848 * valprint.c (val_print_fields): bitfield printing didn't handle
849 byte order. Indirect through a few more fns to cope.
851 * values.c (modify_field): also cope with byte order.
853 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
855 Cleanup for release 3.94.2:
857 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
858 include files. Roll version to 3.94.2.
860 * coffread.c (init_stringtab): Read length into unsigned char
861 array before swapping; don't assume 32-bit longs.
863 * target.c (target_info): Don't bother with get_sym_file, just use
864 the symfile global variable.
865 * symtab.h, symfile.c (get_sym_file): Delete it.
867 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
868 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
869 (read_type): Replace one more error() with complain().
871 * mipsread.c (parse_partial_symbols): Replace printf with complain.
873 * i960-tdep.c: Fix copyright attribution.
875 * config.gdb: Quote all backquotes in doublequotes. You can
876 quote me on that. BSD 4.4 shell found this one.
878 * infptrace.c (throughout): The third argument to ptrace is an
881 * infrun.c (wait_for_inferior): When program has terminated, we
882 have to call target_terminal_ours before we pop that target off
883 the stack (e.g. before a call to target_kill or
884 target_mourn_inferior). This fixes problem where a program
885 terminates, then GDB stops for (tty output) and you have to type
886 "fg" to the shell to resume it. FIXME: This code for what to
887 do after termination really should be in normal_stop instead.
889 * gdbcore.h (read_memory_check): Change declaration; it changed
892 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
893 4.4 prereleases, this avoids a bug in their sgtty compatability
895 * remote.c: Use terminal.h rather than hand-rolling the same.
897 * signame.c, signame.h (psignal): Arg is unsigned, not int.
898 * utils.c (strsave, strstr): Fix arg types.
899 * valprint.c (val_print): lint
901 MIPS symbol table support from Per Bothner:
903 * symfile.c (symtab_fns): Remove initializer table that needs to
904 be hacked for each new symbol file format supported.
905 (add_symtab_fns): New function, chains symbol table
906 handlers into the global list.
907 (symfile_init): Search this list.
908 * symfile.h: Add next pointer, declare add_symtab_fns.
909 * coffread.c (_initialize_coffread): Call add_symtab_fns.
910 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
912 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
913 symbol *). Thus, we no longer need the hack to trash
914 pst->filename. Good, since that hack confused code in symfile.c!
916 (reorder_symtabs, destroy_all_symtabs): Removed static
917 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
918 Instead, the latter now uses a temporary array (stack-allocated
919 from an obstack, and then freed).
921 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
922 haven't been set in the outermost stBlock of a procedure. This was
923 a problem with f77 binaries on Ultrix 4.?.
925 (new_symtab, new_symbol, new_type): Continue changing code to use
926 obstacks more and otherwise conform to dbxread internal style.
927 Made the free_code of symtabs be free_linetable (as in dbxread)
928 instead of free_contents. This implies memory leaks when reading
929 a new symbol table, until the conversion is finished. Did change
930 (struct symbol) and (struct type) to be allocated on the
931 symbol_obstack. Blocks and blockvectors are among the things
934 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
935 tested much, but it solved one problem (reported by Meissner), and
936 cleans up some other things. The problem happened when an
937 included file contains actual code (functions) and not just
938 definitions. The mips coff is a little inconvenient there, since
939 it may cause a procedure to be mapped to the wrong psymtab.
941 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
942 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
943 this will need work for the new core paradigm.
945 Opcode patches from the net:
947 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
948 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
949 missing altogether - they are added here. From Bruce Bauman.
950 * mips-opcode.h: The low mask for C0 instructions was too small.
951 From Garrett Lau. I modified the fix to check the entire 32-bit
954 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
957 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
959 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
961 * dbxread.c (read_type): Pointer subtraction (value_sub in
962 valarith.c) sometimes failed because the types of the
963 pointers being subtracted were not identical.
964 These differed because dbxread.c was allocating pointer types
965 using dbx_alloc_type+smash_to_pointer_type instead of
966 lookup_pointer_type. I failed to find a justification for the
967 former, so I changed it to use the latter. Similarly, I
968 replaced smash_to_function_type by lookup_function_type,
969 and smash_to_reference_type by lookup_reference_type.
971 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
972 _initialize_mipsread): corresponding changes.
974 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
976 * source.c (mod_path): Do tilde_expand on each component of the path,
977 rather than on the (list of) paths as a whole.
978 (print_source_lines): Set first_line_listed in addition to
979 current_source_symtab and current_source_line. If the source was
980 not findable, after a "dir" command to fix the problem,
981 a "list" would get the wrong lines.
983 While I was there... (gnu):
985 * dbxread.c (read_type): Change error to complaint.
987 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
989 First attempt at detailed understanding of symbol table memory alloc.
991 * dbxread.c (dbx_symfile_read): Free our string table if we
992 aren't the mainline. Free the "info" struct since we're done with
994 (init_psymbol_list): Free any previously allocated psymbol lists.
995 (): FIXME: Should realloc-down the psymbol lists when done reading
996 the main symbol file?
998 * symmisc.c (free_symtab): Free fullname field too.
1000 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1001 (REGISTER_ADDR): Make result type unsigned int.
1003 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1004 define REGEX must also define REGEX1 (its dependency).

1021 * gdb-int.texinfo (Host versus Target): Add section on what is
1022 a "host" feature versus what is a "target" feature.

1025 (object search path) as conveniently as the source search path.
1026 * environ.c (set_in_environ): Set some vars in GDB's environment,
1027 in addition to the child's. PATH, G960BASE, G960BIN for starters.

1041 in raw hex as well as float format, regardless of whether it is
1042 a "virtual" convertible register.
1043 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1044 regs as a double, just in case it's being used that way.
1045 * values.c (unpack_long): Comment on array/function coercion.
1046 (unpack_double): Argument is in target byte order now. For
1047 integer arguments, just call unpack_long and float the result.
1048 * m68k-tdep.c: include defs.h for "const" handling.
1049 * remote-nindy.c: Use ieee-float stuff.
1050 (nindy_fetch_registers): Unpack double regs to host double, then
1052 (nindy_store_registers): Pack extendeds to host double, flip

1064 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1066 * coredep.c (fetch_core_registers): Pass end-address of register
1067 section to register_addr as expected. Don't call supply_register
1068 if we'd just pass it garbage.
1070 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1072 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.

1105 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1106 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1107 * tconfig/nindy960: Remove reference to coffstrip.o.
1109 * Makefile.dist: Roll version number to 3.94.1 (not yet final).

1117 * inftarg.c (child_detach): Pop the child_ops vector if the
1118 detach is successful.
1119 * remote-nindy.c (nindy_create_inferior): Don't push a new
1120 nindy_ops since nindy uses the same one for execution and memory
1122 * core.c (core_ops): Use child_attach and child_create_inferior
1123 rather than default attach and create_inferior functions.
1125 Handle floating point registers in core files.
1127 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1128 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1129 This version untested since BFD doesn't yet support sun3 core
1131 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1132 conventions. Fix comments and style. This version has not
1133 been compiled yet, since we have no HP inhouse.
1134 * core.c (get_core_registers): Look for two sections, ".reg"
1135 and ".reg2", and pass both to fetch_core_registers sequentially.
1137 Revise directory path yet again.
1139 * source.c (forget_cached_source_info): Not static any more.
1140 (init_source_path): New default source path is "$cdir:$cwd".
1141 (dir_command): Handle variable arguments ($cdir, $cwd).
1142 (source_info): Print "Compilation directory" rather than
1143 "Originally compiled in" to remind people of $cdir.
1144 (openp): If the path contains $cwd, use current directory.
1145 (open_source_file): If compilation directory is known, replace
1146 first $cdir in path with the compilation directory.
1147 (print_source_lines): Even if we can't print the lines, set the
1148 current symtab and line for future commands like "info source" or
1149 "breakpoint". Also, error message now contains the file name,
1150 line number, and file access error message.
1151 (_initialize_source): Fix help text to describe changes.
1152 * main.c (cd_command): Forget cached source info when we chdir.
1153 * utils.c (strstr): Add simple implementation.

1157 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1158 Byte-swap COFF symbol tables if necessary when reading them in.
1159 Use complain() to replace error message in one spot. Needs
1160 corresponding change in bfd/coff-code.h to make some symbol
1161 swapping routines non-static.
1163 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)

1173 declarations of errno.
1175 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1177 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1178 <rpc/rpc.h> and <rpc/types.h>.
1180 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1182 * i960-tdep.c (examine_prologue): Add new argument limit,
1183 which stops the scan at the end of the prologue, or at the PC.
1184 This fixes a problem where it walks down into the code for the
1185 user's statements if that code looks like function prologues.
1186 Mark Fox and I have been bouncing this code back and forth, making
1187 small changes to it. Callers changed to match.
1189 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1191 Cleanup for gdb-3.94 release final:
1193 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1194 the .c files from vx-share and nindy-share, from the various
1195 macros, since they are not found via ALLDEPFILES.
1196 (SFILES): Add tm-i960.h.
1197 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1198 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1200 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1201 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

1205 * am29k-tdep.c: Add contribution line.
1206 (examine_prologue): Cache information about function prologues in
1207 the misc-function-vector to avoid lots of references over the
1208 serial line while examining instructions.
1210 * core.c (core_close): New function made from cleanup_core.
1212 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1213 remote-vx.c, remote.c, target.c, target.h,
1214 Update target_ops vector to add attach, close, and load entries.
1215 Use add_syms_addr_command, not add_file_addr_command, for
1216 add_file. Break out close routine from existing code.
1218 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1219 they are in an obstack.
1220 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1222 (define_symbol): Add symbol type parameter; change callers;
1223 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1224 it to influence the symbol class on the i960.
1225 (define_symbol): Swap LOC_CONST's into target byte order.
1227 * exec.c (exec_close): New function.
1228 (exec_file_command): Call it.
1230 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1231 Fix byte order of frame pointer.
1232 (read_var_value): Result of 0 if var's value can't be found,
1233 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1234 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1235 (locate_var_value): Use read_var_value and use its lazy address
1236 as the location of the var's value. Lint.
1238 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1241 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1242 obsolete Intel versions in favor of vxgdb versions.
1243 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1244 code dealing with byte order of values, which Intel did in host byte
1245 order rather than gdb-4's target byte order.
1246 (i960_frame_chain_valid): Move to nindy-tdep.c.
1247 (examine_prologue, skip_prologue, frame_find_saved_regs,
1248 frame_args_address, leafproc_return, saved_pc_after_call,
1249 pop_frame): Add vxgdb versions from Mark Fox.
1250 (examine_prologue, frame_struct_result_address): Add code
1251 to deal with the saved value of G13 (struct return address
1253 (frame_args_address): Modify Mark's version to prefer the
1254 saved value over the current value in the topmost frame.
1255 Cache result in the frame info to avoid performance hair in
1257 (print_fault): Add gdb960 code for printing faults.
1258 (_initialize_i960): Actually call check_host.
1260 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1261 add stub routines. FIXME, these currently just return zero!
1263 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1264 (attach_command): Call target_attach, not target_open, now.
1266 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1267 (child_attach): Rename from child_open.
1268 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1269 don't confuse it with a zero step_resume_break_address.
1271 * inftarg.c (child_detach): Eliminate inferior_pid test.
1272 (child_files_info): Clean up message a bit.
1273 (child_ops): Use child_attach, not child_open, to attach.
1275 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1276 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1277 findvar.c to here, since it depends on the contents of the
1278 shadow_contents of breakpoints, but keep if #if 0 since it is
1281 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1284 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1285 (ptype_command, display_command): Eliminate have_inferior_p and
1286 have_core_file_p in favor of target_has_stack or
1287 target_has_execution.
1288 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1289 code for actually finding the values of arguments, though we still
1290 keep track of the maximum stack offset for use in printing unnamed
1291 arguments. Handle missing FRAME_ARGS_ADDRESS.
1293 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1294 (struct nindy_regs): Define registers passed to/from nindy.
1295 (nindy_fetch_registers, nindy_store-registers): Translate between
1296 nindy and GDB formats for the registers.
1297 (dcache_init): Statically allocate the cache, since it was being
1298 allocated by a malloc that was never freed anyway.
1299 (nindy_create_inferior): Error, not core dump, if no exec file.
1300 (nindy_before_main_loop): Use target_load, not target_add_file.
1302 * remote-vx.c (net_load): Specify large timeout for load
1303 requests. Allow user to break out with INTERRUPT.
1304 (net_break): Remove useless code, clean up. Change callers.
1305 (parse-args, skip_white_space, find_white_space): Clean up arg
1306 parsing to cope with quoted strings.
1307 (net_wait, net_quit): Never call error, just return status.
1308 (vx_read_register, vx_write_register): Cleanup status checking.
1309 #ifdef the code based on which CPU we are using (960 or 68k),
1310 FIXME, this should be completely general but it isn't yet.
1311 (vx_xfer_memory, vx_resume): Cleanup status checking.
1312 (vx_run_files_info): Improve message.
1313 (vx_load_command): Renamed from vx_add_file_command. Allow load
1315 (net_ptrace): Remove unused routine.
1316 (vx_wait): Adopt code from vxgdb960 to cope with broken
1317 connections to target machine and prompt to disconnect. Remove
1318 debug printouts. Map some EVENT_'s to SIGnals.
1319 (add_symbol_stub, vx_open): Print names of object files we found,
1320 and "ok" if we read their symbols OK. Clarify output in general.
1321 (vx_attach, vx_detach, vx_kill): Add these commands.
1322 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1323 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1324 "info files" output, and create_inferior, since we already have
1327 * stack.c (frame_info): Replace Frame_unknown with 0.
1328 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1329 (return_command): Pop until the PC matches as well as the FP,
1330 so it works even if the FP is shared with another function,
1331 as in "frameless" or "leaf" procedures.
1333 * symfile.c (load_command): renamed from add_file_target_command.
1334 (add_syms_addr_command): renamed from add_file_addr_command.
1335 (add_syms_command): Stub to call target_add_syms.
1336 (_initialize_symfile): Change command names and descriptions,
1337 add-file => add-syms, and load from alias to its own command.
1339 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1340 maybe_kill_then_create_inferior): Default for attempts to start
1341 a process, if one is already running, is to ask about killing
1342 it and retry if yes.
1343 (upstack_create_inferior): #if-0 it, strata obsolete it.
1344 (push_target, unpush_target, pop_target): to_close() a target
1345 before unstacking it.
1346 (target_info): Renamed from target_files_info.
1347 (_initialize_targets): Rename "i files" as "i target", accessible
1350 * target.h: Improve comments about the target_ vectored routines.
1352 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
1353 Convert commenting style to standard GNU style.

1355 (SKIP_PROLOGUE): No longer a no-op.
1356 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1357 (*_REGNUM): Sort register numbers.
1358 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1359 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1360 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1361 are now 10 byte extendeds, not 8 byte doubles.
1362 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1363 for nindy versus vxworks targets. FIXME, this should possibly go
1364 in the target vector.
1365 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1366 frame_saved_regs and arg pointer with each frame.
1367 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1368 (FRAME_ARGS_ADDRESS): Use cached result.
1369 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1370 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1371 (PRINT_RAMDON_SIGNAL): Call print_fault.
1372 (POP_FRAME): Now works.
1374 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1375 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1376 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1377 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1380 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1381 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1383 * valarith.c (value_subscripted_rvalue): Avoid handling
1384 floats and doubles specially; it gave alignment errors. Lint.
1386 * valops.c (value_of_variable, value_of_this): Error if unknown
1389 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1390 to avoid alignment problems.
1391 (value_print): Handle unknown value address.
1392 (cplus_val_print): Two args are ignored; remove them. Change caller.
1393 (val_print): Use unpack_long rather than pointer-deref.
1396 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1397 to avoid alignment problems.
1398 (value_being_returned): Error if return value unknown.
1399 (set_return_value): Add bogosity warning, FIXME. *
1401 * TODO: A woman's work is never done.
1403 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1404 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1405 Add ieee-float.o to OBS.
1406 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1407 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1408 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1410 Changes to generalize the VxWorks RPC protocol slightly, to handle
1411 i960 as well as 68000.
1413 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1414 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1415 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1416 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1417 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1418 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1419 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1420 so they will move in target byte order rather than network
1421 byte order (happens to be the same).
1423 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1425 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1427 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1430 Add contribution lines to various files, showing where they
1433 * breakpoint.c (break_insn, check_break_insn_size,
1434 read_memory_nobpt): Remove to mem-break.c.
1436 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1439 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1440 entry has bad register number. This change is not
1441 tested in this release, FIXME.
1443 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1446 * value.h: Force value's contents field to be aligned to hold
1447 at least a double or a long long (if supported). This avoids
1448 doing bcopy's in and out of the contents field.
1450 (step_1): Avoid coredump under obscure circumstances when we
1453 * symtab.h (misc_info): Add field to misc function vector for
1454 any kind of cached information the target code desires. AMD
1455 29000 uses this to avoid repeating examine_function_prologue's.
1457 * coffread.c: Lint. Remove static symfile, read_section_header.
1458 core.c (have_core_file_p): Lint: remove.
1459 expprint.c (print_subexp): Lint.
1460 infptrace.c, valops.c, valprint.c: lint.
1462 Roll in changes from vxgdb-5.0.1:
1464 * symtab.h: Comment byte order of each address class. Add
1465 LOC_LOCAL_ARG for frame-relative args (960).
1466 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1467 symtab.c, symmisc.c: ditto.
1469 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1471 * remote.c (remote_resume): Error if resume with a signal.
1473 * symfile.c (prim_record_misc_function): Clear misc_info.
1474 (fill_in_vptr_fieldno): Check stub type of arg.
1476 * valops.c (value_cast): Avoid looking up names of types whose
1477 name we don't know, to prevent coredump. Sun CC produces typedef
1478 rtx and the name of *rtx is zero...
1480 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1482 Roll in changes from final AMD 29000 port (Tiemann).
1484 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
1485 for ../include/a.out.encap.h. This might not work now that BFD
1486 is separately compiled. Instead, BFD support for encap will have
1487 to translate machine type 29k into the right COFF_MAGIC.
1489 * infcmd.c: Remove references to inferior_pid that aren't used
1490 in actual ptrace calls; use target_has_execution, etc.
1491 (have_inferior_p): Remove function.
1492 (program_info): Print target info rather than "process number";
1493 avoid gratuitous messages unless from_tty.
1494 (run_stack_dummy, finish_command): Set proceed_to_finish.
1495 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
1496 main.c: Lint. Lose have_inferior_p().
1497 inferior.h (have_inferior_p): Remove, lint.
1498 (proceed_to_finish): Add flag to ask that all regs be saved
1499 by normal_stop, for the few commands that need it, speeding up
1500 serial I/O. Add comments to stop_registers.
1502 * remote-eb.c: Remove newline from breakpoint message we grep
1503 for. Never time out when running the user program.
1507 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1509 Roll in changes from vxgdb-5.0.1:
1511 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
1512 symbol in its raw form, we are processing an unlinked ".o" file.
1513 See if the target environment has assigned it an address, using
1514 target_lookup_symbol (VxWorks does), and enter it into the symtab
1517 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
1518 68k versions for a simpler version that assumes zero FP at bottom.
1519 Fixes bug of truncated stack reports.
1521 * target.h (target_lookup_symbol): Define this routine's args
1522 and result, finally.
1524 * target.c (nosymbol): Default routine for target_lookup_symbol.
1525 (target_default): Default lookup_symbol and call_function too.
1526 (files_info): Only print has_all_memory warning if a non-dummy
1529 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
1530 vx_convert_from_virtual): If target does not have floating point,
1531 zero register "values", and avoid doing cross-net conversions.
1532 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
1533 (vx_open): Rearrange code that attaches to target and reads
1534 symbols for all loaded modules, to work if some of the modules
1535 are not accessible. Add symbol_stub() and add_symbol_stub()
1536 as callbacks from catch_errors(). Allow connect attempt to be
1537 interrupted painlessly with ^C (FIXME, there are still some bugs
1538 if the interrupt happens during symbol reading.). Print
1539 final message with puts_filtered, since symbol messages are
1544 * main.c (catch_errors): Only print errstring if non-null.
1545 (command_loop): Avoid an ioctl per command to test ISATTY.
1547 * remote-vx.c (net_load): make static; avoid sophomoric msg.
1548 (vx_xfer_memory): Return correct result!
1549 (vx_files_info): Indicate whether target has float or not.
1550 (vx_lookup_symbol): Complain, not error, if target gone.
1551 (vx_open): Print "Connected" msg before disabling immediate-quit.
1552 [FIXME: lookup_symbol and vx_open changes need testing.]
1554 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
1555 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
1556 contributor lines and update copyrights to 1991.
1558 Changes from an attempted H-PUX host port:
1560 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
1561 defines PT_ATTACH and PT_DETACH but not PT_KILL.
1562 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
1563 * remote-vx.c: include <sys/time.h> for HPUX.
1564 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
1565 "core_file_command" routine to BFD regime. May not work yet.
1567 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
1569 * xgdb.c: Replace X10 version with some VJ version.
1570 (FIXME: Its copyright assignment is not on record.)
1571 * xgdb.c: Update include files to X11R4 (Xaw crud).
1572 (xgdb_display_source, create_text_widget): fix call to
1573 get_filename_and_charpos. Rewack source window stuff for X11R4
1574 (gleaned from include files, and "nm's" of binary libraries, since
1575 I had no doc available).
1576 (append_selection, append_selection_word): Disable with FIXME
1577 since R4 changed interface here.
1578 (create_buttons): Add back the old set of buttons.
1579 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
1581 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
1582 Roll VERSION to 3.94 (not yet final though).
1584 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1586 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
1587 obstack_int_grow, obstack_int_grow_fast): Eliminate
1588 cast on left of assignment, which gives MIPS cc fits and is
1591 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
1592 F_ALIAS. Use printf, not fprintf, when not passing a file
1594 (compare_opcodes): Check that identical instructions have
1595 identical opcodes, complain otherwise.
1597 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
1598 was reported by Roland McGrath.
1599 (unimp): Only match if exactly zero instruction. (Roland)
1600 (branches and traps): Generate all variations of these
1601 instructions with macros, based on a single call that defines
1602 each condition name and its binary representation.
1603 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
1605 * valprint.c (val_print_fields): Take, and use, format parameter.
1606 This means that "p/x struct" again prints the elements in the
1607 desired format. Changed callers.
1609 * stack.c (frame_info): Use filtered output, and indicate wrap
1610 points. Remove kludgy formatting designed to avoid line wrap.
1612 * utils.c (wrap_here): If the line is already full (because
1613 we had printed a long indent or long wrapped string), do an
1614 immediate newline-and-indent.
1616 * m68k-pinsn.c (print_insn_arg): Bugfix from
1618 instruction is incorrectly disassembled as bkpt #8.
1620 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
1622 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
1623 and then will dump core (sometimes). I traced it back to an
1624 uninitialized symfile_name in psymtab_to_symtab.
1625 (const_vol_complaint): Add quotes to message.
1626 (define_symbol): Only believe line number if gcc_compiled.
1627 Avoid allocating symbol if we will not return it.
1629 Add target strata support so that newly established targets go
1630 into their right place in the target stack (e.g. a new exec file
1631 doesn't wipe out the ability to access the running process).
1633 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
1634 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
1635 and initialize it properly in all the targets.
1637 * target.h: Document strata. Change return type of push_target.
1639 * target.c (nomemory): new function for dummy memory access.
1640 (tcomplain): Rename complain, now also used in symfile.c.
1641 (push_target): Push targets within strata. New return value shows
1642 whether new target is on top of stack or not. Always keep dummy
1644 (target_files_info): Ignore dummy target.
1646 * core.c (core_open): Warn user, and skip accessing file, if the
1647 core target is not the topmost target in the stack.
1648 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
1651 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
1652 target_ops, it doesn't belong there since we have no regs there.
1653 Change name of target from machine => memory to clarify.
1655 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
1657 * Freeze version 3.93 for release.
1659 * Makefile.dist: Handle vx-share and nindy-share subdirs
1660 properly when building gdb.tar.Z.
1662 * symtab.c: lint; add no_symtab_msg to consolidate the messages
1663 printed in various places, so I could change just one copy.
1665 * dbxread.c, coffread.c: Change references to bfd->iostream
1666 to cast to FILE *, now that BFD avoids needing types defined
1667 in other header files.
1669 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1671 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
1672 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
1673 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
1674 (actually gcc -Wall).
1676 * dbxread.c: Remove first_global_sym, last_global_sym, since
1677 they are never referenced.
1679 * defs.h (baud_rate): Declare.
1680 main.c: Define it, and add the -b option to set it.
1682 * gdb-int.texinfo: Add text on how to define a new host or target
1683 architecture, prompted by Per Bothner's questions about MIPS
1686 * gdb.texinfo: Document "complaints". Change doc of -q since
1687 gdb no longer prints the copyright and blurb if you specify a file
1688 name to be debugged (just like Emacs). Add doc for Nindy-specific
1689 command line flags for specifying target serial port and such.
1690 Update copyright to 1991.
1692 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
1693 has taken over for us the job of ripping up executable files. The
1694 crud caused Per Bothner's port to not compile.
1696 * infrun.c (normal_stop): Avoid printing "Program exited
1697 normally" if we are in batch mode. This allows a GDB which
1698 executes a program on a target system, to behave like a Unix
1699 command (input from stdin, output to stdout, no extraneous
1702 * main.c (main): Allow additional machine-dependent command line
1703 options to be specified with the ADDITIONAL_OPTIONS,
1704 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
1705 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
1706 processing to occur just before the main loop with
1707 BEFORE_MAIN_LOOP_HOOK.
1708 (main): If a "core file" argument is specified, and it is not a
1709 core file, try it as a process ID to attach.
1710 (symbol_completion_function): Attempt to cope with
1711 "show screen-" TAB, not very successfully. This needs more work,
1713 (batch_file): New function, returns whether we are reading
1714 commands from an interactive tty on stdin, or from somewhere else.
1715 Called by normal_stop since it doesn't get from_tty passed down
1716 to it like many commands do.
1718 * remote-nindy.c: Handle command line options for nindy
1720 (nindy_before_main_loop): Prompt user for tty name if they
1721 don't specify it before getting to the interactive command loop.
1723 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
1724 and -r command line options. Also add hook before main loop
1725 to make it easy to specify a tty.
1727 * TODO: More things to do, one done.
1729 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
1731 * dbxread.c: Make complaint() calls pass pointer, not struct.
1732 Add complaints about badly formatted C++ type information
1733 (const/volatile indicator, and parse errors resulting in
1734 error_type). Fix C++ virtual member fn comment.
1735 (read_struct_type): Avoid bumping pointer if we got a parse
1736 error; this prevents our walking beyond the end of a string.
1737 Terminate loop on null char as well as semicolon.
1738 (process_one_symbol): Fix the LBRAC fix so that it uses the
1739 last previous SLINE, FUN, or SO record's PC address. C++ debug
1740 symbols did not have SLINE records in a useful order compared
1741 to the LBRAC records.
1742 (define_symbol): Handle "catch" records.
1744 * symtab.c (check_stub_type): Added new complain
1745 `stub_noname_complain' and added a consistency check to
1746 keep the debugger from crashing when finishing from an
1747 exception frame. A real fix will be needed later.
1749 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1751 * infcmd.c (attach_command): Make global.
1753 * Makefile.dist (REMOTE_OBS): Make these compile by default,
1754 but make them easy to comment out. Perhaps later they should
1755 be enabled by what CPU you configure for? FIXME.
1756 (VERSION): Roll to 3.93.
1757 (pinsn.o): Remove rule for obsolete file.
1758 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
1760 Run down a problem that manifested by printing the wrong function
1761 name in stack traces of read_ofile_symtab. Turned out that the
1762 problem was the SunOS 4.1.1 (and previous) C compiler outputs
1763 the LBRAC symbol with an address in the *data* segment, which
1764 blew our binary search through the blocks.
1766 * dbxread.c: Use the complain() facility consistently to bitch
1767 about problems in the symbol file we are reading.
1768 (finish_block): Add code to check the nesting of the blocks;
1769 complain and Procrust them to fit if wrong.
1770 (make_blockvector): Check the order of the blocks, complain
1771 [but don't cope] if wrong.
1772 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
1773 symbols to be sure their PC value is greater than the last SLINE
1774 (line number) symbol we've seen, complaining and adopting the
1775 SLINE PC value if wrong.
1777 * symfile.h (struct complaint, complaint_root, complain,
1778 clear_complaints): Add.
1779 * symfile.c (complain, complaint_root, clear_complaints): Add
1780 facility to deal with non-fatal complaints and to regularize their
1782 (symbol_file_add): Clear complaint counters to allow new complaints.
1783 (initialize_symfile): Add 'set complaints' and 'show complaints'.
1785 * dbxread.c (dbx_symfile_read): Remember the address and size
1786 of the string table for the main symbol file, so we won't read it
1788 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
1789 to avoid reading the string table yet again. Lint.
1790 (throughout): Improve filtered output, including word wrap.
1791 (read_range_type): Improve Bothner's fix to handle other types too.
1793 * utils.c: Improve line wrap implementation. Handle unlimited
1794 width by making chars_per_line unsigned.
1795 (puts_filtered): New, easy, function.
1797 * defs.h (puts_filtered): add.
1799 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
1800 call the identical sort_symtab_syms() in symfile.c instead.
1802 * expread.y: Suggest the `file' command rather than `symbol-file'.
1804 * command.h (enum var_types): Add zinteger for seroable
1806 * command.c (do_setshow_command): Handle var_zinteger. Restructure
1807 nested if's into a switch.
1809 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
1810 we did not stop because of a breakpoint (it must have been for
1811 some other reason, like a "stepi"), so don't print anything.
1813 * symtab.c: Include <sys/types.h> all the time. Now that BFD
1814 doesn't include <sys/types.h>, old SunOS's require it for
1819 A test port of gdb-3.92.6 to the Sony NEWS.
1822 Don't normally link in remote- or vx stuff.
1823 Some of it doesn't compile, and it wastes space for 99% of the users.
1824 Remove reference to no-longer-used HAVE_VPRINTF.
1825 Fixed BFD_DEP typo to BFD_DIR.
1827 Fix cast in arg to bfd_h_getlong.
1828 Make char *prefix be const.
1829 Fix how certain range types are mapped into builtin unsigned int types.
1831 Remove 2 #includes. They cause errors (on Sony, at least),
1832 and aren't needed (they wern't in earlier versions).
1834 print_address_symbolic should never demangle labels
1835 (since it prints *assembler-level* labels).
1837 [This was superseded by the change to printcmd below.]
1840 Add some "volatile" return types to avoid warnings.
1841 If MISSING_VPRINTF add vprintf function and not just macro
1842 (since vprintf is used in printcmd.c).
1844 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
1845 (The latter isn't grokked by some PCC-based compilers.)
1847 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
1849 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
1850 * nindy-share/coffstrip.c
1851 Added some forward declarations (otherwise, gcc complains
1852 about implicit extern redefined as static).
1854 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1856 Changes inspired by Per Bothner:
1857 * printcmd.c (print_address_symbolic): Take additional parameter
1858 specifying whether to demangle.
1859 (print_address): Pass in asm_demangle to control demangling.
1860 (print_address_demangle): New fn, takes explicit arg to control
1862 * utils.c: Add new vars demangle and asm_demangle, and let them
1864 (fputs_demangled): If !demangle, just print the argument.
1865 (fprint_symbol): If !demangle, just print raw symbol.
1866 * valprint.c (val_print): Call print_address_demangle rather than
1867 print_address, to cause demangling to depend on the global
1868 rather than assembler-level demangling setting.
1869 * WHATS.NEW, gdb.texinfo: Document.
1871 * main.c (show_command): Show all settings if no arg.
1872 (initialize_main): Make "info set" the same as naked "show".
1873 * command.c (cmd_show_list): Handle prefix commands in the
1874 list, and print the name of the setting as well as its English
1875 description and value.
1877 Allow gdb functions to specify where a line should wrap if it
1878 exceeds the size of a terminal line. Use it to make the output
1880 * utils.c (set_screen_width_command): New fn, mallocs a buffer
1881 of the right size when screen width changes.
1882 (set_screensize_command, screensize_info): Remove #if 0'd fns.
1883 (wrap_here): New fn, indicates a point in the output where we
1884 should wrap the line rather than just letting it overflow at a
1886 (fputs_filtered): Implement wrapping.
1887 (n_spaces): New fn, returns a pointer to N spaces.
1888 (print_spaces_filtered): Use n_spaces.
1889 * defs.h (n_spaces): Declare.
1890 * stack.c (print_frame_info): Wrap with 4-space indent after
1891 fn name and before filename and line number.
1892 * printcmd.c (print_frame_args): Wrap with 4-space indent
1893 before each argument name is printed.
1894 * valprint.c (value_print): Wrap with no indentation before
1896 (val_print_fields): Wrap with indentation relative to nesting
1897 level before each field name.
1898 (val_print): Wrap with nesting indentation before array elements.
1899 * command.c (do_setshow_command): Avoid extra newlines,
1900 wrap with 4-space indent around values printed, end with period.
1901 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
1903 * breakpoint.c (breakpoint_1): Implement addressprint for
1904 "info breakpoints" display. Change file name and line number
1905 format to " at file:nnn" rather than " (file line nnn)".
1906 * gdb.texinfo: Document.
1909 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1911 Frozen for gdb-3.92.6 release.
1913 README, WHATS.NEW: Update for 3.92.6 release.
1915 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
1916 coffread.o from configs since it is now built by default.
1917 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
1918 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
1919 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
1920 from configs since it is now built by default.
1922 Makefile.dist: Update for release 3.92.6. Handle files that
1923 have been moved to ../include, ../getopt, or ../bfd. Add
1924 saber.suppress and tests directory. Add config.status to
1925 the release (it will say "none").
1927 coredep.c: Minor formatting fixes.
1929 These changes were made in early December but only checked in now:
1930 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
1931 nindy-share/nindy.c: lint
1932 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
1933 register values coming back from the target; we store values
1934 in target byte order everywhere.
1936 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
1938 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
1940 * valprint.c (cplus_val_print, val_print_fields): New functions,
1941 which print C++ objects. They conspire to avoid printing a
1942 virtual base class more than once, following all the twists and
1943 turns of C++ virtual base rules.
1944 (val_print): Call the above rather than do it by hand.
1946 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
1947 symbol file, not for added files like shared libs. This really
1948 needs to be generalized to a timestamp per file.
1950 * core.c (cleanup_core): Avoid coredump if no core file.
1952 * config.gdb: Accept -host or -target in place of +host or
1955 * coffread.c (find_linenos): Avoid desupported BFD interface
1956 to line numbers. We still read them manually rather than using
1957 BFD's "generic" features.
1959 * gdbrc.tex, threecol.tex: Add GDB reference card and its
1961 Makefile.dist: Add refcard to OTHERS list for creating tar files.
1963 * Makefile.dist: Eliminate use of $< in explicit targets.
1965 * readline/Makefile: Use $< rather than $*.c, which does not
1966 include the VPATH in GNU Make.
1968 * tconfig/i960-bout, tconfig/i960-coff: These are identical
1969 copies of tconfig/i960, added for global configuration
1970 compatability. All i960 versions can read both coff and b.out.
1972 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
1973 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
1976 * TODO: Think of more things to do.
1978 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
1980 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
1981 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
1982 64-bit float conversion.
1984 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
1985 equivalent to sun?os4 so global config works.
1987 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
1991 * main.c: Only declare linesize once; declare pagesize not at
1992 all, since it is never used.
1993 (main): Clear newly allocated line before it is used.
1995 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
1997 Further stabilization for the Intel 960.
1999 * Makefile.dist: Parameterize the location of the "include"
2000 and "bfd" directories, as well as "getopt". Add symfile.c.
2001 Link in both dbxread and coffread. Fix up "make depend" to
2002 rewack the locations of include, bfd, and getopt in its output.
2004 * README: Document moving include files, improve some of
2007 * coffread.c: Move common code out to symfile.c. Change
2008 symbol_file_command style interface to use new *_symfile_init
2009 and *_symfile_read interface under BFD. Use BFD internal
2010 info to locate line table, symbols, etc.
2012 * core.c (core_fetch_registers): Rename to get_core_registers
2013 to avoid confusion with fetch_core_registers.
2014 (register_addr): Move to coredep.c, which is already machine
2015 dependent. This leaves core.c pretty clean of dependencies.
2017 * coredep.c (register_addr): Accept this routine from core.c.
2019 * dbxread.c: Move common code (with coffread.c, etc) into new
2020 symfile.c. Each psymtab now contains a pointer to the
2021 format-dependent function that knows how to read it in. Make
2023 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2024 (process_one_symbol): Add code to complain about a "compiler bug
2025 we muzzle here", if we actually see it.
2027 * eval.c (evaluate_subexp): Insert missing "break" statements
2028 in code that determines whether a variable is an lvalue in
2029 memory, register, or whatever. I detected this via a compiler
2030 bug in which it *almost* mashed out the whole switch statement.
2032 * gdb-int.texinfo: Add minor sections on configuring gdb for
2033 release, and about the README file.
2035 * infcmd.c (registers_info): Fix formatting somewhat. Still
2036 not as pretty as before, but it handles byte swapping.
2038 * remote-nindy.c: If data cache routines are interrupted while
2039 waiting for the remote end, be sure that any uninitialized cache
2040 blocks are on the free list, not on the valid list!
2042 * symfile.h: Flesh out this header file with all the various
2043 routines and variables that have been merged in from dbxread.c
2044 coffread.c, and symtab.c to symfile.c.
2046 * symfile.c: New file, containing code common to dbxread.c,
2047 coffread.c, and some code from symtab.c. All generic code for
2048 reading symbol files should be in here now.
2049 (unrecord_misc_function): Remove unused function.
2051 * symtab.h: Remove file-reading things to symfile.h.
2053 * symtab.c: Remove file-reading things to symfile.c.
2055 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2056 to decode i960 fault types.
2058 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2059 target.c: Change type of the "resume" function from int to void,
2060 since its result was never used.
2062 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2064 * main.c: Replace "stupid" with "caution"; you now "set caution
2067 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2069 * infcmd.c (do_registers_info): Call val_print to deal with the
2070 byte order of the registers being printed. FIXME, this makes
2071 the formatting of the output uglier.
2073 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2074 defined, call it for signals the debugger doesn't itself use.
2075 The i960 uses this for more detailed fault information.
2077 * remote.c (remote_open): If arg is null, print help rather than
2080 * sparc-xdep.c (register_valid): Avoid declaring size, since
2081 various modules will think of various sizes depending on the
2082 architecture of their tm-file. FIXME, we need protection against
2083 actually entering one of those modules, which would clobber
2084 storage if not for the target architecture compiled into gdb.
2086 * stack.c (up_command, down_command): Always print the frame
2088 (up_silently_command, down_silently_command): New commands
2091 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2093 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2094 more parameters than it used to.
2096 * findvar.c (registers): Increase slop to 256 bytes, which should
2097 protect us against even most RISC machines with large register
2099 (locate_var_value): Move declaration inside related ifdef.
2101 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2102 throughout, to avoid throwing away buffered input from the board.
2103 (nindy_wait): Supply_register takes addr_of_value, not value.
2104 (i960_print_fault): Renamed from i80960_fault.
2105 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2106 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2108 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2109 we can set the PC in the call to proceed(). Unpush nindy_ops
2110 before pushing it on top, to avoid message to user. Eliminate
2111 commentary from Unix machines that just misleads here.
2112 (reset_command): Fix error message to suggest target command.
2114 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2116 Release 3.92.5 as frozen.
2118 Stabilize the merged release...with help from lint, Saber C,
2121 Everywhere: Add include files needed to declare return types
2122 of functions called.
2124 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2126 * breakpoint.h: Add undeclared breakpoint functions, and some
2127 functions for display handling since I couldn't think of a better
2130 * breakpoint.c (insert_breakpoints): Make code for disabling
2131 shared library bkpts more likely to work. It's used when we
2132 rerun a program and stop before the shared library has been
2134 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2135 cast from pointer, so it squeezes through catch_errors.
2136 (bpstat_stop_status): Fix logic broken some time ago. We now
2137 always create a bpstat if the stop address matches a breakpoint,
2138 even if we don't stop there -- just like the old code used to do
2139 before I got my fingers into it (sigh).
2140 (breakpoint_1): Print "ignore count" after "stop only if"
2141 condition, since that's how it actually works.
2142 (mention): Handle watchpoints as well as breakpoints.
2143 (watch_command): use set_raw_breakpoint and mention to do most
2144 of the work (and initialize all the fields!). Only pass one
2145 arg to parse_c_expression, since that's all it takes.
2147 * command.c (not_just_help_class_command): Rename arg to args
2148 since we ignore "unused argument" warnings on vars named "args".
2149 inflow.c (child_terminal_info): ditto.
2150 infptrace.c (kill_inferior): ditto
2151 main.c (catch_errors, version_info, quit_command, pwd_command,
2152 source_command, dump_me_command, editing_info,
2153 set_history_size_command, set_history, show_history,
2155 stack.c (locals_info): ditto
2156 target.c (target_files_info): ditto
2157 valprint.c (set_input_radix, set_output_radix): ditto
2159 * core.c: Remove old variables for handling core and exec file
2160 sections (data_start, data_end, stack_start, stack_end,
2161 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2162 text_end, exec_data_start, exec_data_end, text_offset,
2163 exec_data_offset, data_offset, stack_offset). They're
2164 superseded the more general build_section_table and
2166 (get_exec_file): Mention the `file' command.
2167 (read_memory_check): Rename to memory_error, and only call it
2168 in the case of an actual error.
2169 (read_memory, write_memory): call memory_error.
2170 (core_fetch_registers): Register section name is ".reg".
2172 coredep.c: Remove a bunch of crud now that all this file does
2173 is pull the registers out of a core file.
2174 (fetch_core_registers): Rewrite to actually work, I hope.
2176 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2177 Replace index() with strchr(). Remove all the pre-BFD macro
2178 definitions for accessing the symbol file.
2179 (struct dbx_symfile_info): Encapsulate the information that
2180 dbx_symfile_init needs to pass to dbx_symfile_read in this
2183 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2184 dbx_symfile_discard): Rearrange symbol file reading to divide
2185 the format-specific part from the format-independent part,
2186 leaving the format-independent part such as file name expansion
2187 and opening in symtab.c. This replaces
2188 partial_symbol_file_open and partial_symbol_file_read.
2189 Symbol_file_read, add_file, add_file_target_command,
2190 add_file_addr_command move to symtab.c. Pass an explicit
2191 "mainline" flag for when reading the main symbol table, rather
2192 than relying on the offset address to be zero or nonzero.
2194 (dbx_symfile_read): Don't allow void *'s to be printed as
2196 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2197 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2198 macro" debug version really work.
2199 (read_dbx_symtab): Remove unref'd parameter inclink.
2200 Avoid swapping N_SLINE symbols, for speed.
2201 Merge N_TEXT!N_EXT case with the other external symbol
2202 definitions' case. Add comments.
2203 (start_psymtab): Allocate the symfile name in the psymtab on
2204 the psymbol_obstack, rather than using the caller's storage.
2205 (end_psymtab): Only allocate a dependencies list if there are
2207 (psymtab_to_symtab_2): Use BFD when reopening file to read
2208 its symbols for real.
2209 (read_struct_type): Add FIXME comments where it needs work
2211 (read_huge_number): Add FIXME about overflows.
2212 (read_range_type): Add FIXME about comparing a long to 1<<32.
2214 * coffread.c: Minor changes to move things closer to the new
2215 regime with symtab.c and dbxread.c Major work is still needed
2218 * exec.c (exec_file_command): Remove old variables (see core.c
2220 (xfer_memory): If memory transfer is right at the end of a
2221 section, don't lose.
2223 * findvar.c (get_saved_register): If value is in a real
2224 register, LVAL is lval_register, not lval_memory.
2226 frame.h: Declare print_sel_frame and record_selected_frame.
2228 gdb-int.texinfo: New file, for GDB internals documentation.
2229 Very simple, unformatted doc of cleanups is there for now.
2231 gdbcore.h: Remove obsolete variables that described a.out
2232 section addresses and offsets. (See core.c above.)
2233 Declare fetch_core_registers and registers_fetched.
2235 getopt.c: Declare char *alloca(); even on SPARC.
2237 infcmd.c (run_command): Call target_kill rather than
2239 (step_command, next_command, stepi_command, nexti_command):
2240 Declare from_tty parameter even though we don't use it.
2241 (run_stack_dummy): argument BUFFER is a char array, not
2242 a pointer to REGISTER_TYPE.
2243 (finish_command): using_struct_return needed a value *,
2244 not a struct symbol *.
2246 * infptrace.c (child_xfer_memory): To avoid dependency on
2247 where sections are in memory, try PT_WRITE_D and if that fails,
2248 try PT_WRITE_I. Most Unixes don't care which you use.
2250 * infrun.c (step_resume_break_shadow): Change to array to
2251 match other breakpoint shadow storage.
2252 (clear_proceed_status): Pass address of bpstat to
2253 bpstat_clear, not the bpstat itself.
2254 (child_create_inferior): FIXME comment about if the child
2256 (start_inferior): Remove old function.
2257 (child_open): Use target_kill rather than kill_inferior.
2258 (wait_for_inferior): Ditto.
2259 (insert_step_breakpoint, remote_step_breakpoint): Use
2260 new step_resume_break_shadow.
2262 * inftarg.c (child_wait): If all child processes die,
2263 pretend that the one being waited for exited with signal 42.
2265 * main.c (command_line_input): When scanning for comments,
2266 don't coredump on unclosed quotes.
2267 (quit_command): Use target_kill rther than kill_inferior.
2268 (_initialize_main): Rename class_user from "user" to
2271 * printcmd.c (print_command_1): Initialize "fmt" if no format
2272 is specified by the user.
2273 (print_frame_args): Only add to args_printed if we are
2274 actually fetching args from the stack (avoiding undefined
2276 (_initialize_printcmd): Remove bogus \{ from string.
2278 * remote-eb.c (eb_open): Avoid coredump on no argument.
2280 * remote-nindy.c: Bring out of Intel environment into new
2281 target environment. Remove all conditional compilation on
2282 I80960. Massive hacking throughout.
2283 (nindy_xfer_inferior_memory): New routine stolen from
2285 (nindy_create_inferior): New routine pieced together, probably
2286 not quite working yet.
2287 (nindy_ops): New target_ops struct for nindy.
2289 * remote-vx.c: Use write_memory rather than target_write_memory
2290 to get error checking.
2291 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2293 (vx_create_inferior): Use target_terminal_ours...
2295 * signame.c (_initialize_signame): Always initialize, since
2296 we need the table for things other than psignal.
2298 * solib.c (solib_add): Use symbol_file_add, not add_file.
2299 (solib_address): Return boolean result rather than struct
2300 pointer which nobody else knows the type of.
2302 * sparc-tdep.c, valops.c: Use write_memory rather than
2303 target_write_memory, to get error checking.
2305 * stack.c (locals_info, catch_info, args_info,
2306 get_selected_block, frame_command, up_command): Use
2307 target_has_stack, rather than have_inferior_p or
2310 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2312 * symfile.h: New file, defining the interface between the
2313 generic and object-file-specific symbol reading code.
2315 * symtab.c: Move generic symbol-reading interface to symtab.c,
2316 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2317 table to map BFD targets to symbol-reading modules in GDB.
2318 Change index to strchr.
2319 (lookup_struct_elt_type): Use error() rather than hand-made
2320 simulations thereof.
2321 (lookup_partial_symbol): Speedup slightly when length == 0.
2322 (symbol_file_add): New function.
2323 (symbol_file_command): Call it.
2324 (symfile_open, symfile_init): New function.
2325 (add_file_target_command, add_file_addr_command): moved from
2328 * target.c (target_command): use target_kill.
2330 * target.h (target_files_info): Don't declare, never called
2333 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2334 files to determine stack end address.
2336 * valarith.c (value_x_binop, value_x_unop): Change error message
2337 to be more useful. Pass proper argument to value_struct_elt.
2339 * valops.c (value_assign): FIXME comment that long long
2340 bitfields will break here.
2342 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2343 Update `make saber_gdb' to work better.
2345 * TODO: A woman's work is never done.
2347 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2348 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2349 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2350 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2351 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2352 valops.c, valprint.c, exec.c: Lint.
2355 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2357 Continuing Intel 960 port merge of GDB.
2359 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2360 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2361 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2362 Wack over "make depend" so it handles files in subdirectories
2363 vx-share, nindy-share, bfd, and in the current directory.
2365 * blockframe.c (get_prev_frame_info): Remove fatal error
2366 if stack not defined.
2368 * core.c (core_open, core_detach): New functions that handle
2369 the old "core-file" command as "target core" and "detach" instead.
2370 (core_file_command): Call them.
2371 (core_xfer_memory): Use common routine xfer_memory.
2373 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2374 dbxread now uses bfd for everything but symbol reading itself.
2375 BFD internals are used to drag out the relevant file offsets.
2376 (partial_symbol_file_open): Change args all around for BFD.
2378 * symtab.c: Rename "value" to "val" everywhere, so we can
2380 (symbol_file_command): New command, moved from dbxread.c
2381 and coffread.c. It uses BFD to read the file, then vectors
2382 based on its type, to dbx or coff symbol readers.
2383 * symtab.h: Extern a few vars for symbol_file_command.
2385 * target.h: Breakpoint takes a char * save area, not a char **.
2387 * valprint.c (val_print): When unpacking bitfields, offset
2388 the address in gdb of the value, if it is declared with a shorter
2389 type. Remove the last "runtime kludge test" of host byte order.
2391 * utils.c: Remove old my_bfd_read routine.
2393 * stack.c (frame_info): Use target_has_stack. Print program counter
2394 register's actual name rather than "pc", since it's called the
2395 "ip" (instruction pointer) on the i960 (sigh).
2397 * target.c (target_command): Add command for selecting a target
2398 type and calling its open routine. This is used for initiating
2399 communication with a particular target, in a generic way.
2401 * tm-i960.h: Update for modern gdb. Remove semicolons from
2402 various macros. Handle reading struct return convention, and
2403 error-out attempts to return structs with the "return" command.
2404 Be sure gdb doesn't think we know how to call functions in the
2407 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2408 to i960_xxx in lower case.
2409 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2410 not being defined yet.
2412 * remote.c (remote_open): Call start_remote to initialize
2413 wait_for_inferior during open.
2414 (remote_xfer_inferior_memory): Return length written rather
2417 * remote-vx.c (target_command -> vx_open): Use new generic
2419 * remote-eb.c, inftarg.c, exec.c: ditto.
2421 * infrun.c: Fix comments.
2422 (attach_program -> child_open): Use new generic target command.
2423 (wait_for_inferior): Clear saved register values before target_wait,
2424 so target_wait can set some of them if convenient.
2426 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2427 Return success indicator, not void.
2428 (child_xfer_memory): Avoid fetching initial word if we'll
2429 overwrite it anyway.
2431 * infcmd.c (attach_command): Use new generic target open routine.
2432 (_initialize_infcmd): Update doc on attach and detach commands.
2433 (do_registers_info): Merge in a byte-order problem as a FIXME
2436 * findvar.c (find_saved_register): Avoid problem in current frame.
2437 (read_relative_register): Ditto.
2438 (write_register): Convert byte order on the way out.
2440 * exec.c (file_command): Add.
2441 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
2442 (xfer_memory): Common function between core_xfer_memory and
2444 (exec_xfer_memory): Use it.
2446 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
2448 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
2449 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
2450 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
2452 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
2454 Merge Intel 960 port of gdb, continuing...
2456 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
2457 symbol_file_command): Pass from_tty arg to hush 'em up.
2459 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
2460 Add magic numbers for 960 COFF format.
2462 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
2464 Merge Intel 960 port of gdb, from Intel "1.2" release.
2466 CHANGE_LOG entries from their port, which was based on
2469 Thu Sep 6 11:02:22 PDT 1990
2470 Remove temp file if download is interrupted.
2472 Wed Aug 1 09:08:33 PDT 1990
2473 Now uses binary protocol to talk to NINDY.
2474 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
2475 Times out after 5 seconds when trying to talk to NINDY.
2477 Tue May 29 12:54:49 PDT 1990
2478 Added variable baud rate (-b switch).
2479 Source code reorganization.
2481 Thu Apr 26 11:09:55 PDT 1990
2482 More cleanup of batch mode; specifically, execute "-s", "-e", and
2483 "-se" switches as soon as they are encountered on the invocation line.
2485 Fri Apr 20 13:47:15 PDT 1990
2488 Thu Apr 19 09:54:28 PDT 1990
2489 Add 'reset' command.
2491 Wed Apr 18 09:48:07 PDT 1990
2492 After opening remote tty, wait for 1 second to go by without input
2493 from it before trying to talk to NINDY (fixes problems with the
2494 Heurikon HK80/V960E).
2496 Mon Apr 4 16:33:05 PDT 1990
2497 Some output was not being suppressed in 'batch' mode.
2499 Thu Mar 22 15:31:11 PST 1990
2500 Ask user if old symbol table should be deleted when new file is
2503 Allow user to run a program downloaded before gdb960 was brought up.
2505 Correct "exec-file" help message for i80960 context.
2507 Correct bug in calculating user space address: could occasionally
2508 corrupt user program.
2510 Make sure to zero low-order bits in rip's because of bug in 960CA
2511 A-step part: could cause operation faults when "next"ing across
2514 Correct bug that made it impossible to get source line numbers for
2515 code loaded at addresses higher than 0x7fffffff.
2517 Wed Jan 10 12:43:22 PST 1990
2518 Open remote tty for exclusive use.
2520 Fri Jan 5 12:14:42 PST 1990
2521 Correct disassembly (CA manual was right after all):
2522 opcode for sysctl is 0x659
2524 Mon Oct 23 12:03:04 PDT 1989
2525 Use G960BASE and G960BIN environment variables to find 'sx' utility.
2527 Mon Oct 16 14:15:09 PDT 1989
2528 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
2530 Mon Oct 2 15:56:31 PDT 1989
2532 Added 960CA disassembly support.
2534 To simplify maintenance:
2535 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
2537 - eliminated opcode.h: incorporates tables into i960-pinsn.c
2538 - moved 960-specific routines from i960-pinsn.c to i960-md.c
2539 - made disassembly interface identical to that in gdmp960.
2543 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
2545 * target.h: Allow targets to stack. Add target_has_memory,
2546 _registers, etc. Restructure memory access and "info files"
2547 to walk the target stack.
2548 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
2549 target.c: Change tables to match target.h.
2550 * inflow.c (child_mourn_inferior): pop child_ops.
2551 (generic_mourn_inferior): Use new has_stack flag.
2552 * infptrace.c (child_xfer_memory): New memory regime.
2553 * inftarg.c (child_files_info): New "info files" regime.
2554 * remote-eb.c: New memory regime, new info files.
2555 * remote-vx.c: New memory regime, new info files. Now use
2556 separate targets for VxWorks attachment to machine, and
2557 actually running a process under VxWorks, since one has
2558 stack & execution & regs and the other doesn't.
2559 * remote.c: New memory regime, new info files.
2560 * sparc-xdep.c (fetch_core-registers): New memory regime.
2561 * target.c: New routines and support for stacked targets,
2562 new memory regime, new info files regime.
2565 Generalize section handling for an arbitrary number of sections,
2566 including use of the new BFD (binary file) library.
2567 * gdbcore.h: Add struct section_table.
2568 * exec.c (build_section_table): Iterate all sections and
2569 record what gdb needs to know about them.
2570 (exec_command): Use it.
2571 (exec_xfer_memory): Use the table.
2572 (exec_files_info): Print the table.
2573 * core.c (core_file_command, core_xfer_memory, core_files_info):
2575 * source.c (find_source_lines): Use bfd_get_mtime.
2576 * dbxread.c: Quick changes to make it compile with new BFD.
2577 * utils.c (error): Avoid using bfd_error in generic routines.
2579 * core.c (core_fetch_registers): Get from the ".regs" section of
2581 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
2583 * inferior.h (attach_flag): Export.
2584 * infcmd.c (run_command): use new target_create_inferior.
2585 * infrun.c (child_create_inferior): Don't return result.
2586 * Makefile.dist (VERSION): 3.91.4.
2588 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
2590 * breakpoint.c (bpstat_num): Handle breakpoints which have
2591 since been deleted, such as temporary breakpoints.
2592 infcmd.c (program_info): ditto.
2594 * core.c (core_file_command): Display the frame where the core
2599 * remote-vx.c (target_command): Merge in target command from
2600 targ-vx.c. A few other cleanups.
2602 * TODO, Projects: Lots more stuff to do...
2604 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
2606 Massive changes to wall off the remote-debugging interface
2607 behind a function vector. The port to handle VxWorks targets
2608 is also part of this.
2610 All files: Replace references to renamed functions,
2611 remove references to remote_debugging, remove references to
2612 have_include_file, have_core_file in favor of target_has_stack,
2613 target_has_memory, etc.
2615 * Modularize the breakpoint interface.
2616 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
2617 a breakpoint instruction.
2618 breakpoint.c: struct breakpoint's shadow_contents now sized as
2620 (insert_breakpoints): Vector to target to install breakpoints.
2621 (remove_breakpoints): Vector to target here too.
2622 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
2623 sparc-tdep.c (single_step): Use new breakpoint interface for
2624 the single-step breakpoints.
2625 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
2626 New file, contains routines to insert and remove breakpoints by
2627 reading out the old contents and later replacing them. This is
2628 how ptrace breakpoints work, and many remote systems as well.
2630 * tm-vxworks68.h: New config file, overrides a few things for
2631 Wind River's preferences.
2633 * target.h: New file, for transfer vector used to talk to the
2634 inferior (child, attached, core, exec, remote, etc). All accesses
2635 to the thing being debugged should come through these vectors.
2636 target.c: New file, routines to handle transfer vector.
2637 (various files): Add transfer vectors XXX_ops for the various
2638 targets and pseudo-targets (core files, etc) we support.
2640 * breakpoint.c (bpstat_stop_status): Further explorations of
2641 watchpoints and why things don't work all the time.
2642 (bpstat_alloc): New fn to allocate a bpstat and chain it.
2644 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
2645 the local gdbinit if it doesn't already have it.
2647 * core.c (core_ops): add and install.
2648 Allow core debugging without exec file.
2650 * dbxread.c (free_and_init_header_files): Merge two fns.
2651 (end_symtab): Free named symbol table when a new version comes in.
2652 (read_dbx_symtab): Relocate all kinds of symbols with base
2653 address. First step toward handling different text, data, bss
2655 (add_file_addr_command): Renamed add_file_command.
2656 (add_file_command): Vector to remote handler.
2657 Add "load" as an alias for "add-file" command.
2659 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
2660 non-returning functions.
2662 * exec.c: Add exec_ops, and push it as a target when an exec
2665 * infcmd.c (run_command): Pass executable file name and arg list
2666 separately when starting an inferior. Permit "run" when no exec
2667 file is specified, for VxWorks.
2668 (detach_command): Move to child_detach in inftarg.c.
2670 * inftarg.c: New file. Unix-child-specific routines, and the
2671 child_ops structure.
2673 * inferior.h (registers): Export "registers" as the way for
2674 target dependent register handlers to find gdb's local copy of
2675 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
2676 since it is now used by places that want wait_for_inferior to
2677 handle the grunge but want to see every trap from the inferior.
2679 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
2680 Eliminate remote_debugging hooks in terminal handling.
2682 * infrun.c: Replace start_inferior with child_create_inferior.
2683 Move all the hair of Unix shells and ptrace idiosyncracies into
2684 child_create_inferior, so remote handlers don't have to deal.
2685 Remove running_in_shell. Rename stop_after_attach to
2686 stop_soon_quietly, and use it in a few other places where we want
2687 to just call wait_for_inferior and get control back on the first
2688 trap. trap_expected now never takes a value > 1.
2689 (init_wait_for_inferior): Initialize static vars when a new
2692 main.c (gdbinit): Add new hook for .gdbinit file name, let
2693 it be overridden by config files as GDBINIT_FILENAME.
2694 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
2695 Both of these are used for VxWorks gdb.
2697 mcheck.c: rename include file "gmalloc.c" to avoid problems
2698 with system include file "malloc.c".
2700 param-no-tm.h: New include file, same as param.h but does not
2701 include the default "tm.h" file. This is used in files where
2702 the target is known, e.g. remote-eb.c or sparc-xdep.c.
2704 param.h: Now just a shell that includes tm.h and param-no-tm.h.
2706 remote-vx.c: New file, VxWorks remote debugging support. Uses
2707 RPC routines that are shared with the target system, in directory
2710 remote.c: Vectorize remote interface.
2712 source.c: Globalize source_path, and make an alias "l" for "list"
2713 since we now have the "load" command.
2715 sparc-xdep.c: Use new param-no-tm.h.
2717 symmisc.c (free_named_symtab): Add new function from Wind River.
2718 However, ifdef it out for now while we think about what it should
2721 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
2723 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
2724 non-Unix-children handle this with their own code in the target
2727 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
2728 source and target lists. Add vx-share to default list of include
2729 directories. Add new files to src and target lists: mem-break,
2730 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
2731 ${srcdir} versions of munch and createtags are used.
2733 * valops.c (find_function_addr): Split out of call_function.
2734 (call_function_by_hand): Rename call_function; this function
2735 calls functions in the target by laboriously patching the target
2736 word-by-word with the right stack, args, regs, etc.
2739 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
2741 Handle AMD 29000 a bit better.
2743 * remote-eb.c (readchar): Mask received char log to make it readable.
2744 (remote_start): Pass arguments down to executing program.
2745 Make startaddr unsigned.
2746 infrun.c (start_inferior): Accept args, pass them to
2748 infcmd.c (run_command): Pass args down to start_inferior.
2750 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
2751 the target object file format.
2752 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
2754 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
2755 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
2757 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
2759 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
2760 * TODO: We did a few things, we have more to do though.
2762 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
2763 * inflow.c (inferior_died): Clear deferred stores.
2765 * Debug problems with dummy frames and calls to the inferior.
2766 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
2767 * sparc-tdep.c (do_restore_insn): Simplify.
2768 (sparc_frame_find_saved_regs): Simplify and fix what we find.
2769 (sparc_push_dummy_frame): Simplify and fix what we push.
2770 (sparc_pop_frame): Slightly more hair here, deciding whether
2771 we are restoring a saved PC or returning to a return address in %i7.
2772 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
2774 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
2775 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
2776 * obstack.h (chunkfun): ditto.
2777 * defs.h (xmalloc, xrealloc): ditto
2779 * utils.c (quit): Grab the terminal from the child if necessary.
2781 * inflow.c (term_status_command): Rename to term_info, change
2784 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
2785 (is_delayed_branch): Speed up.
2786 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
2787 Still missing some float ops, and needs testing.
2789 * Support for input and output radixes other than base 10
2790 * defs.h (input_radix, output_radix): Declare.
2791 * expread.y (yyparse, parse_number): Handle changes of input
2792 radix, and ambiguous names-or-numbers in radixes >10.
2793 * printcmd.c (print_scalar_formatted): Print formatted hex
2794 numbers in varying column widths.
2795 * valprint.c (val_print): Use output_format to print scalar ints.
2796 (set_input_radix, set_output_radix, set_radix): Create.
2797 (set_output_radix): Set output_format from output_radix.
2798 (_initialize_valprint): add `set radix' but leave the others off.
2800 * main.c (execute_command): Let stupid questions be turned off.
2801 (_initialize_main): Handle "set stupidity", etc.
2803 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
2804 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
2806 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
2808 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
2809 bfd stuff is still screwed up, but with some manual work, it
2812 * breakpoint.c (bpstat_do_actions): Start over if a command
2813 proceeds the inferior, since the inferior will have stopped and
2814 will need to have its new stop-actions taken care of.
2816 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
2817 compiler fits, simplify it.
2819 * gdb.texinfo (directory command): Doc new dir command.
2820 source.c (directory_command): "dir" now puts things on the front
2821 of the path, moves dups up front, and handles multiple names
2822 on the command line, inserting each one in order. It also
2823 blows away cached line and full_filename info.
2825 * stack.c (backtrace_command): Skip "more stack frames follow"
2828 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
2829 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
2830 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
2831 The only odd one was Gould NP1, which had defined vprintf to
2835 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
2836 variable, inspect_it.
2837 valprint.c (print_string, val_print): Use the global inspect_it
2838 to indicate whether to print in Epoch style or normal style.
2840 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
2842 * printcmd.c (call_command): add an alias for the "print" command
2843 which runs expressions and doesn't print the result if void.
2844 (print_command_1): implement it.
2846 * command.c: Remove #if 0'd code. Initialize all the fields
2847 in add_cmd (). Rename do_nothing_command to
2848 not_just_help_class_command, and make it externally visible.
2849 command.h: add user_commands to struct.
2850 * main.c (define_command): Don't overload c->function with a char
2851 string as well as a function pointer.
2853 * eval.c (evaluate_subexp): Reinstall tiemann changes to
2854 calling convention of value_struct_elt () that got dropped in
2857 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
2858 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
2860 * tm-sparc.h (POP_FRAME): replace some constants with defines.
2862 * sparc-xdep.c (store_inferior_registers): defer stores to regs
2863 until a good time (e.g. when we are about to run the child),
2864 saving ptrace calls.
2865 * infrun.c (proceed): handle DO_DEFERRED_STORES.
2866 * tm-sparc.h: define DO_DEFERRED_STORES.
2868 * sparc-xdep.c (store_inferior_registers): when storing float
2869 registers, don't store stack regs too. When storing the SP,
2870 however, DO store the stack regs too. This fixes a bug in which
2871 the dummy frame is not recognized when a call_function finishes,
2872 because its frame pointer (in the stack regs) was never
2874 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
2875 even though we don't know how to read them from an inferior.
2876 valops.c (call_function): Comment about storing SP.
2878 * infrun.c (save_inferior_status): Save away the original bpstat
2879 chain so it can be restored later. Install the copied version for
2880 use by whoever saved the status. It will be blow away by
2881 restore_inferior_status, and the original chain restored. This is
2882 important for people who have pointers into the original.
2884 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
2885 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
2886 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
2889 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
2891 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
2892 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
2893 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
2895 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
2897 * Merge Mike Tiemann's multiple inheritance changes from Sun.
2898 Store the baseclasses in a type struct starting from array element
2899 0 rather than from the unusual array element 1.
2901 dbxread.c: the above.
2902 (virtual_context): Add
2903 Read new debug information about which virtual function table
2904 a virtual function is from, and store it in fn_field.fcontext.
2906 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
2907 TYPE_FN_FIELD_STATIC_P.
2909 symtab.c: the above.
2910 valops.c: the above. Handle pointer casts of object *'s.
2911 (search_struct_method): Add.
2912 (value_struct_elt): First arg is now a pointer to a value, and is
2915 valprint.c: the above.
2916 values.c (value_virtual_fn_field): Add type arg. Handle
2917 offsetting to the proper object when calling virtual fns.
2919 (baseclass_addr): Add valuep arg.
2921 * README: Document the current state of BFD config (missing).
2922 * TODO, ChangeLog, Makefile.dist: Roll version.
2923 * WHATS.NEW: Add summary of changes since 3.5.
2925 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
2927 * dbxread.c (read_struct_type): Clear bit vectors whenever
2929 symtab.c (B_CLRALL): define.
2931 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
2932 using == rather than =. Huh... This fixes the dreaded problem
2933 wherein builtin_type_int becomes TYPE_CODE_FLT.
2935 * core.c (info_files): Show the inferior pid.
2937 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
2938 already knows how to look in the source directory.
2940 * Remove psymtab hair from many places. Remove duplicated code
2941 for searching symbol tables. Hide psymtabs from most places.
2942 Make it fast to get from a psymtab to its symtab.
2944 blockframe.c (blockvector_for_pc): Remove psymtab hair.
2945 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2946 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2947 dbxread.c: export psymtab_to_symtab, make it work if called N times.
2948 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
2949 new symtab completely. New psymtabs get symtab pointer
2950 initialized to zero. Remove MI warning printf.
2951 symtab.h: Comments. Add psymtab to symtab pointer.
2952 (PSYMTAB_TO_SYMTAB): New macro.
2953 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
2954 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
2956 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
2958 (print_frame_info): Avoid special-casing symbols that have not yet
2961 * source.c (open_source_file): Quick path if we have already
2962 located the source file by its full name.
2964 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
2965 find_pc_psymtab. When a name is found in the misc function
2966 vector, search the symbol table for its mangled name, not the
2967 name that the user typed.
2969 * bfd.h: Fix missing comment terminators, make #endifs match.
2971 * valarith.c (value_less): Handle unsigned int comparisons.
2972 Add FIXME about pointer compares, which assume host and target
2973 pointers are the same.
2975 * command.c (do_nothing_command): lint
2976 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
2977 fix comments on debug symbol format for visibility. Actually set
2978 visibility of symbols.
2979 main.c (echo_command): lint; use <readline/history.h>.
2980 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
2981 obstack.h (_obstack_blank): Rearrange pointer math to avoid
2982 pointing past end of allocated memory; saber complains.
2983 obstack.h: Declare the external functions that we use.
2984 valarith.h: use <string.h>
2985 solib.c (solib_add): lint.
2987 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
2989 * main.c (initialize_main): Default info_verbose to off, now that
2990 symbol reading is fast.
2991 (quit_command): Avoid clobbering exec_bfd while quitting.
2993 * Initial BFD (binary file diddling library) merger:
2994 coffread.c: Change AOUTHDR to struct exe_hdr.
2996 core.c: initialize initialized data at compile time.
2997 (core_file_command): Move from coredep.c, convert to bfd.
2998 (xfer_core_file): Convert to bfd.
2999 exec.c (exec_file_command): use bfd routines.
3001 mips-tdep.c: Remove exec_file_command and friends.
3004 * coredep.c: (fetch_core_registers) Convert core_file_command to
3005 fetch_core_registers.
3006 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3008 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3009 (my_bfd_read): More bogosity, which I don't think we call.
3010 (program_name): Remove this atrocity asap!
3012 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3015 values.c: allocate_repeat_value was not clearing the
3016 optimized_out field.
3017 (value_static_field): minor stylistic fix (wrong macro was used).
3018 valops.c (value_struct_elt_for_address): didn't work for C++
3021 * signame.c (_initialize_signame): Initialize signal names once.
3023 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3024 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3025 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3027 * remote-eb.c: Support user-settable baud rates on the serial port.
3029 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3031 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3033 * tconfig/sun3os4: Remove warning about native assembler,
3034 since it also occurs in the xconfig file.
3036 * findvar.c (registers): Allocate some slop after `registers'
3037 to prevent stray accesses from trashing the next variable.
3039 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3040 on the sun-3, by changing the #ifdef from `sun3' (which is not
3041 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3042 vars, which happened to follow `registers' in the executable.
3044 * readline/history.c (history_search): Heed gcc-2's advice
3045 and parenthesize && inside ||).
3047 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3048 tm-29k.c: Insert FSF copyright headers.
3050 * remote-eb.c: Better comments.
3052 * Makefile.dist: Update to 3.91.6.
3053 * TODO: note PREPARE_TO_STORE problem.
3055 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3057 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3059 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3061 * infrun.c (wait_for_inferior, at end): Don't set up
3062 prev_* if the inferior no longer exists.
3064 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3065 CANNOT_EXECUTE_STACK.
3066 valops.c (call_function): Use it.
3068 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3070 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3071 infrun.c (wait_for_inferior, 2 places): Use it.
3073 * values.c (value_being_returned): Only use
3074 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3076 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3077 right thing for remote-eb.c.
3079 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3080 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3082 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3083 (FRAME_FIND_SAVED_REGS).
3085 * findvar.c ({fetch,store}_registers): Check for
3086 REMOTE_{FETCH_STORE}_REGISTER macro.
3088 * findvar.c (get_saved_register): Add argument lval and
3089 change meaning of argument addr.
3090 findvar.c: Change calls to get_saved_register to reflect
3091 new calling convention.
3092 valops.c (value_assign): Use get_saved_register instead of
3093 find_saved_register.
3095 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3097 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3098 an (uninitialized) pointer to one. Use "&" when passing it
3101 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3103 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3106 * coffread.c (symbol_file_command): Put semicolon after
3108 Put safe_to_init_tdesc_context in #if defined (TDESC).
3109 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3110 coffread.c: #include <sys/stat.h>.
3111 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3112 Add missing ')' in check for "lc%" and friends. Remove
3114 Declare read_one_sym() at top of file.
3115 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3116 MC68WRMAGIC can have the same value without causing a duplicate
3119 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3121 * Allow a Makefile to be built without building the
3122 tm and xm file links that screw up builds in subdirectories.
3123 This is done with `config.gdb none', then you can do things
3124 like `make gdb.tar.Z'.
3125 * tconfig/none: Config file for no target system
3126 * xconfig/none: Config file for no host system
3127 * config.gdb: If no TM or XM files are called out by the
3128 host or target file, don't make links for them.
3130 * cplus-dem.c: Add documentation.
3132 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3133 simple error, so the user's gdb doesn't crash due to some object
3134 file problem (e.g. somebody is rebuilding the file out from under
3137 * printcmd.c (print_address_symbolic): demangle the symbol.
3139 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3140 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3141 (alldeps.mak): sort and uniq all results from this; duplicates
3142 hose gdb.tar.Z link building. Remove RCS files from
3143 tconfig and xconfig. Add config files for sun386. Add
3144 a few odd files to OTHERS and HFILES.
3146 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3148 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3149 Roll version number to 3.91.5. Make lint work in bindir.
3151 * README: Document cross-debugging and new file structure.
3153 * blockframe.c: Lint. Include "value.h" to declare read_register.
3154 (find_pc_partial_function): remove duplicate line.
3156 * command.h: Lint. Declare error_no_arg and dont_repeat.
3158 * tm-news.h: Remove inadvertently duplicated stuff.
3160 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3161 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3163 * config.gdb: Allow `config.gdb host target' form. Clean
3164 up previous change that printed bogus messages when you just said
3167 * core.c: #include "command.h" for lint.
3170 * main.c: Remove some casts of enums. Lint.
3177 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3179 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3180 read it from memory. This will allow us to save ptrace calls
3181 eventually. Changed caller single_step too.
3183 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3184 that we aren't going to use, saving many ptrace calls, especially
3185 when watchpointing or single stepping. Use some #define's for
3187 (store_inferior_registers): Ditto.
3188 (core_file_command): Use some #define's for constants.
3190 * tm-sparc.h: Add #define's for some register numbers, so we
3191 can eliminate the use of random constants in sparc-xdep.c.
3193 * stack.c (frame_command, print_frame_info, up_command,
3194 down_command) Remove frame_changed, since it
3195 causes a bug and doesn't seem to do anything useful. In some
3196 places it was used as a flag, in others as a stack level (?).
3198 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3199 default is to use the portable (vprintf) version rather than the
3201 * xm-news.h (MISSING_VPRINTF): Add.
3203 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3205 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3207 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3208 about linking debugged programs -Bstatic in the sun?os4 config
3209 files in tconfig and xconfig subdirectories.
3211 * main.c (main): Remove unreached exit(0) now that we exit
3214 * Create TODO file for online bug list. There are too many
3215 "little" bugs to keep track of on paper.
3218 rather than kingdon@ai.
3220 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3222 * Makefile.dist (VERSION): 3.91.4 now.
3224 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3225 (condense_misc_bunches): Add sanity check that misc_count is
3226 the same as the number of symbols in the bunch.
3228 * coffread.c: rename init_misc_bunches. Pass an argument
3229 to condense_misc_bunches (a zero).
3231 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3232 every time we are called; don't rely on our caller to do it.
3233 (add_file): Remove call to init_misc_bunches.
3235 * mipsread.c: Only warn, don't error, if unknown symbol types.
3236 This keeps an old gdb from falling on its face if it sees newly
3237 extended symbol info. Rename init_misc_bunches.
3239 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3241 * Merge in changes from Per Bothner for DECstations and other
3242 MIPS stuff. The rest is Bothner speaking:
3244 The next message is a merger of Alessando Forin's mips port with
3245 mine. I've tried to use my good if biased judgment to get
3246 the best of both. It *does* need testing.
3248 Some of the changes are general, *not* mips-specific.
3251 Didn't believe in little-endian bit order.
3252 There are still inconsistencies about whether flags
3253 like BITS_BIG_ENDIAN are integer (#if ...) or
3254 boolean (#ifdef ...). I tried to paper over them.
3256 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3257 Moved some misc_function code that was common to
3258 {dbx,coff,mips}read.c to symtab.c.
3259 In the process, I think I cleaned things up a bit.
3260 At the same time, moved obsavestring and obconcat to symtab.c.
3263 Removed obsolete condense_addl_misc_bunches (use
3264 condense_misc_bunches(1) instead).
3267 Needed to include <sys/dir>, at least on DECstations.
3269 valops.c, mips-tdep.c, tm-mips.h:
3270 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3271 conventions (when STACK_ALIGN is insufficient).
3272 Needed on mips, where doubles need 8-byte alignment,
3273 but ints only need 4.
3276 Removed cruft that was not being used.
3280 Print $ before register-names (I think that makes things a little
3282 Never print two instructions, even if one delays.
3283 Removed hex-disassemble set_cmd. (This is not mips-specific,
3284 so I think the argument is whether it is generally worthwhile or not.
3285 I'm inclined to think not, given how easy it is to
3286 convert between radixes in gdb.)
3289 This is basically Alessando's code.
3290 It doesn't use obstacks; I changed it to use obstacks
3291 in a few minor places where using malloc causes a
3292 memory leak. (Probably, more places could/should be changed.)
3293 I added record_misc_function where it was missing.
3294 In symbol_file_command and add_file_command, I tried
3295 to make the code consistent with more recent versions.
3296 Minor sylistic changes in parse_procedure.
3297 Make a .gdbinfo. psuedo-symbol point back to the real
3298 procedure symbol (using the isym field).
3301 This is basically from my port, but with a lot of details
3302 and a number of routines merged in from Alessando's version.
3303 I basically used my code "raw" backtrace (use heuristics
3304 from the actual code, rather than symbol table info) - though
3305 the idea is Alessandro's. I feel my code is a little cleaner
3306 here, particularly in being a little more flexible, such as being
3307 able to handle gcc-produced code (which it now can).
3308 It also doesn't do frame caching (which is not useful
3309 more recent gdb versions).
3310 I also used my code for push_/pop_dummy, more or less.
3311 I tried to incorporate AF's code for testing sigtramp
3312 while backtracing; I probably got it wrong.
3313 Added mips_print_register, which tries to scrunch as much
3314 information as possible on a screen...
3315 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3316 under mips-pinsn.c), I don't see anything mips-specific here,
3317 and I don't see it being all that useful anyway.
3320 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3321 Use more register names (rather than hard-cases numbers).
3323 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3325 * Hack up 3.90.11 changes:
3327 * Makefile.dist (depend): parameterize $(GCC).
3328 Add solib.c and solib.o.
3329 (readline): Fix vpath for both absolute or relative SRCDIR.
3332 Also, let the part I didn't understand at least compile so
3333 I can test the rest. FIXME.
3335 * dbxread.c: Fix thinko using strcmp.
3336 (init_psymbol_list): declare static.
3337 (partial_symbol_file_open): Comment cleanups better, avoid
3338 cleaning up the string table since the caller will do that.
3339 Move the stat for mod time into symbol_file_command, temporarily.
3340 (There should be a mod time for each symbol file, eventually,
3341 to control its rereading. FIXME.)
3343 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3344 SunOS, which gives error for shared libs otherwise. (From
3345 Schaefer, probably FIXME needs work for portability.)
3347 * solib.c: Move #include "param.h" to work.
3348 Lowercase all the Uppercase Letters In the Messages.
3349 (find_solib): Clean up inferior_so_name for debug printouts.
3350 Allow no argument, to mean all shared libraries.
3352 * symmisc.c: include param.h to get CLEAR_SOLIB.
3354 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3356 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
3357 to 3.90.11. ChangeLog entries below are from this.
3359 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3363 * Makefile.dist (HFILES): Add tm-sunos.h.
3365 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3369 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
3373 * sparc-opcode.h Added single-operand version of rett.
3375 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3377 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
3378 Put parens around gcc_p in expansion.
3380 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3382 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
3384 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3386 * Changes for Sun shared libraries:
3387 blockframe.c (find_pc_partial_function): If a non-text symbol
3388 is found, set *address = pc - FUNCTION_START_OFFSET.
3389 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
3390 Disable breakpoints instead of giving an error.
3391 source.c (select_source_symtab): Initialize cs_pst.
3392 symmisc.c: Call CLEAR_SOLIB if defined.
3393 symtab.h: Make text{low,high} CORE_ADDR not int.
3394 (psymtab): New field addr.
3396 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
3397 (record_misc_function): Give correct type for N_DATA symbols.
3398 (condense_misc_bunches): do "misc_function_count = j" regardless
3400 Take code which is shared between symbol_file_command and
3401 add_file_command and put it into partial_symbol_file_{open,read}.
3402 Split add_file_command into add_file_command and add_file.
3403 Make psymtab_to_symtab read in the string table if the file
3405 Two new parameters to read_dbx_symtab and start_psymtab.
3406 tm-sunos.h: New file.
3408 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3410 * infcmd.c: Change cont_command to continue_command and "cont"
3413 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3415 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
3417 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
3419 * values.c (USE_STRUCT_CONVENTION): Check for structures of
3420 size 1,2,4,8 rather than size < 8.
3422 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
3423 as necessary, not just once.
3425 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3427 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3429 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3431 * tm-news.h: Add CALL_DUMMY_*.
3433 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
3435 * config.gdb: In list_host, list_target, use ${i}, not $i.
3437 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3439 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
3441 * sparc-opcode.h: Change all store floating-point state register
3442 instructions to have the right match & lose fields.
3444 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3446 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
3448 config.gdb: If srcdir != ., create readline directory and
3449 copy a makefile into it.
3451 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
3452 consistency with POSIX.
3454 * breakpoint.c (bpstat_stop_status): Disable watchpoint
3455 when we exit its exp_valid_block.
3457 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
3459 * Makefile.dist: Bump version to 3.91.3.
3461 * Clean up handling of breakpoint commands (somewhat).
3462 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3464 inferior.h: Add breakpoint_proceeded to inferior status struct
3465 and globals; save it and restore it.
3466 (clear_breakpoint_commands): Cleanup, remove old #define.
3468 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3469 (save_inferior_status, restore_inferior_status): handle it also.
3470 (proceed): Remove earlier code that set breakpoint_proceeded.
3471 It is now set only in clear_proceed_status.
3472 (clear_proceed_status): Cleanup, use bpstat_clear rather
3473 than clear_breakpoint_commands. No callers need the stop_bpstat
3474 between clear_proceed_status and proceed.
3476 infcmd.c: Add breakpoint_proceeded definition and comment.
3477 (cont_command, jump_command, signal_command): Move call to
3478 clear_proceed_status right next to call to proceed.
3480 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3481 caller's argument while running down the chain of breakpoints.
3482 Use new variable "breakpoint_proceeded" to determine when
3483 a command that it executes moves the inferior past the
3485 (bpstat_clear): Handle NULL argument.
3486 (bpstat_clear_actions): Avoid useless call to
3487 breakpoint_auto_delete.
3488 (delete_breakpoint): Clean up bpstat's that are pointing to
3489 the deleted breakpoint from the stop_bpstat chain.
3490 (breakpoint_auto_delete): Simplify.
3492 * Clean up handling of EOF, error on stdin, etc. This was
3493 prompted by a network problem that caused gdb to go into an
3494 infinite loop filling up its malloc'd memory.
3496 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
3497 not clear_breakpoints_commands, which is now gone.
3498 (main): If command_loop returns (e.g. from EOF on stdin), do
3499 a quit_command (looping back to command_loop if quit_command
3500 doesn't really quit).
3501 (command_loop): check result from command_line_input and
3502 exit if it returns NULL, rather than passing the NULL to
3504 (gdb_readline): Free malloc'd result space before returning
3507 * utils.c (query): Handle C-d to mean "yes", just as if the
3508 input was not a terminal. Also avoid infinite loop if EOF
3509 occurs in mid-input-line before newline. This allows
3510 query to be used at EOF on stdin with reasonable results.
3512 * infrun.c (proceed): Set breakpoint_proceeded.
3514 * values.c (value_as_long): Avoid infinite recursion for enums.
3515 (_initialize_values): Fix typo in help msg (kingdon).
3517 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
3518 RL_LIB for linking. This allows -lreadline for linking
3519 and nothing for dependencies, once readline is a real library.
3521 * config.gdb: Jim Kingdon: give useful error message if the
3522 host or target type is not recognized.
3524 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
3525 it just defines it. Dumb, but deal with it.
3527 * Jim Kingdon suggests:
3528 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
3530 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
3532 * Makefile.dist (VERSION): Bump version # to 3.91.2.
3534 * Clean up Bothner's changes.
3536 * blockframe.c (clear_pc_function_cache): New function.
3537 * blockframe.c: remake cache_pc_function_* static.
3538 * dbxread.c (symbol_file_command): remove references to
3539 cache_pc_function_* variables.
3540 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
3541 * printcmd.c: Avoid kludging a global variable (addressprint)
3542 to avoid printing the address of a string twice. Instead,
3543 pass the format letter 's' down low enough that it can be seen
3544 to avoid this problem.
3545 (print_formatted): Pass format arg to value_print.
3546 (restore_addressprint): Remove function.
3547 (do_examine): Avoid hacking addressprint, cleanups and such.
3548 (print_frame_args): Add a comment to a Bothner change.
3549 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
3550 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
3551 to wipe out the values cached in blockframe.c.
3552 * symtab.c (find_method): Add comment saying how big you must
3553 allocate to be "big enough". Per being terse again.
3554 * valprint.c (val_print): Handle format letter "s" to print
3555 strings without addresses. Add comment to vtbl printing code
3556 which casts with wild abandon. Rearrange reference-printing
3558 @0xaddr: value (print w/addressprint)
3559 value (print w/~addressprint)
3560 @0xaddr (parameter lists w/addressprint)
3561 or nothing (parameter lists w/o addressprint)
3563 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
3565 * Merge more changes from Per Bothner:
3567 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
3568 annoying) that I tried to improve it. Here are my suggestions.
3570 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
3573 Do automatic de-reference when taking the address of a reference.
3575 Don't deref_ref when printing parameter lists.
3577 More attempts at treating refernences properly.
3579 In val_print, if deref_ref==0, don't print dangling " = ".
3581 Add COERCE_REF macro, which de-references an REF.
3583 * Merge changes from Per Bothner:
3585 * Fixed (Sony news)-specific configuration problems.
3586 * Fixed other problems with using vanilla pcc and libc (enum problems;
3587 assumption that vsprintf exists).
3588 * Some major speed-ups (finc_pc_partial_function now caches a match;
3589 parsing avoids duplicate symbol_lookup calls).
3590 * Changed handling of baseclasses (no longer use baseclasses field
3591 of struct type, use the first n_baseclasses fields instead).
3592 * Various minor changes/fixes, most C++-related.
3595 Cache the most previous match from find_pc_partial_function.
3596 (Save both low and high ends of matching function's pc range.)
3597 This speeds up the loop of infrun.c:wait_for_inferior quite
3598 a bit, and makes step/next commands much zippier.
3600 Added an enum->int cast (otherwise, some compilers barf).
3602 No longer set baseclass offset to 0, since multiple
3603 inheritance now mostly works.
3604 Added a number of casts, to shut up compiler warnings
3605 (after stabs where made enums, not ints).
3606 When discarding a symbol table (in symbol_file_command),
3607 must clear the cache introduced in blockframe.c.
3608 Don't convert $vtbl_ptr_type to vtbl any more.
3609 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
3610 Mask off sign bit emitted by g++ for virtual table offset.
3611 Set voffset to -1 (not 1) for static member functions.
3613 Changed parsing/lexing of names to avoid doing symbol lookup twice
3614 (once when lexing to determine symbol class, once for real).
3615 Now only call symbol_lookup once. Fields of 'this' win especially big.
3617 Subpress printing addr twice in the case of 'x/s addr'.
3619 lookup_basetype_type is no longer used.
3620 Add find_methods as recursive helper function to decode_line_1.
3621 This allows multiple inheritance to work.
3622 Also, once one or more matches has been found, do not look in
3623 base-classes. (Baseclass methods would be overridden, anyway.)
3625 Removed baseclasses array in struct type.
3626 Instead of using baseclasses[i], use fields[i-1].
3627 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
3628 Changed sign convention of voffset (previous was inconsistent).
3630 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
3632 Used to assume existence of vsprintf. Re-written to not need it
3633 if HAVE_VPRINTF is undefined.
3635 typecmp was too pessimistic. Made it less so.
3637 Don't print space after address.
3638 If vtable points to a misc symbol (with 0 offset), print it,
3639 since that indicates the actual class of the object.
3640 Changed ype_print_derivation_info to use new inheritance
3641 scheme (without baseclasses vector).
3643 In value_primitive_field, fixed some bugs left over from previous set of fixes.
3644 Also, changes needed because TYPE_BASECLASSES were removed.
3646 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
3648 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
3651 If there is no path set, and the symbols don't indicate what directory
3652 a file was compiled in, look in the current directory. But either
3653 a path or a known compilation directory will prevent this.
3656 Three independent bug fixes:
3657 * Remove the #if 0 block that breaks some stuff.
3658 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
3659 adapt gdb to either SunOS 4.0.* or 4.1.
3660 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
3663 Instantiate the class T when looking for methods in it. (Tiemann@sun)
3666 (type_print) Demangle the name being printed.
3667 (type_print_base) Handle botched demangling without coredump (tiemann).
3670 (check_stub_method): Document routine.
3671 (tiemann) fix bug for no-arg functions
3672 Avoid clobbering beyond end of malloc'd storage.
3673 Terminate the argument list properly.
3677 * Changes merged by John Gilmore:
3680 In breakpoint_1, use new print_address_symbolic instead
3681 of find_pc_partial_function. (This forces use of assembler-level
3682 addresses, and avoids misleading non-mangled source-level names.)
3684 Generalize ansi argument such that -1 means skip arglist totally.
3685 Removed global variable print_ansi_qualifiers (which made
3686 code non-reentrant), in favor of extra explicit arguments
3687 to internal routines.
3689 Add new helper function print_address_symbolic.
3690 Use find_pc_misc_function instead of find_pc_partial_function
3691 (since we want assembler-level symbols here).
3693 Print unknown function as just "f (...)", not "f (...) (...)".
3694 Use new fputs_demangled explicitly.
3696 Fixed a typing violation (problem: value.h cannot be imported
3697 without renaming many variable in this file).
3698 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
3699 decode_line_1: Moved forward some never-reached code.
3700 Made decode_line_2 skip function prologues correctly.
3702 fputs_filtered should not demangle by default.
3703 Add new fputs_demangled to demangle on demand..
3705 Change value_struct_elt to use value_primitive_field (using recursive
3706 utility function search_struct_field). This allows foo.bar to work
3707 for multiple inheritance (so far only for data fields).
3708 Change check_field in the same way (recursive helper function
3709 to support multiple inheritance).
3710 (Note: there are more of these problems that I haven't fixed.
3711 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
3712 value_of_this: 'this' symbol name is now just "this", note "$this".
3714 Don't print static members.
3715 Avoid printing "members of <type>" if there are none.
3716 Simplified type_print_derivation_info by merging duplicate code.
3717 Remove useless blank lines in type_print_base (ptype command).
3719 Added declaration of new routine value_primitive_field.
3721 Added value_primitive_field which is generalized version of
3722 value_field that can handle multiple inheritance (non-zero offsets etc).
3723 Re-implemented value_field to call value_primitive_field.
3725 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
3727 * infcmd.c -- insert else to avoid 'delete env' coredump when you
3728 delete the whole environment. Karl Berry reported the bug.
3729 * source.c - fix openp to avoid //'s in filenames, which
3730 trigger an Emacs bug causing it to not be able to find files
3731 when running gdb in a window.
3732 * dbxread.c - zap the #if 0 that botches the add-file code.
3733 It seems to work a lot better without all the code commented out.
3735 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
3737 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
3740 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
3742 * Makefile - added a ${CFLAGS} to a couple of entries,
3743 added remote-sa.sparc.c
3744 * added remote.sa-sparc.c, a modification of remote.c
3745 which conducts a dialog directly with the SparcStation prom.
3746 * breakpoint.c, infrun.c, sparcdep.c added
3747 remote_insert_breakpoint(), and remote_remove_breakpoint()
3748 to breakpoint.c instead of directly writing breakpoint instructions.
3749 * sparcdep.c on remote_debugging,there is no need
3750 to remove signle step breakpoint instructions.
3751 * main.c added "-epoch" flag and "int epoch_interface" to main.c
3753 * printcmd.c - epoch interface sends lisp expressions to open up
3754 epoch windows on inspection.
3755 * valprint.c - added arrayprint, and addressprint and made adding
3756 format controls easier
3757 * wait.h added a couple of undef's because we were getting
3758 complaints about WSTOPSIG and WTERMSIG begin redefined.

3783 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
3785 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
3786 should print ANSI qualifiers (such as `const' and `volatile').
3787 All callers changed to call with ANSI == 1, except from
3788 `check_method_stub', which uses old-style syntax.

3828 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
3829 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
3830 when printing the type.
3832 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)

3854 step_resume_break_address != NULL, even if another_trap.
3855 If trap_expected and we enter sigtramp, then set up a
