1 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
4 docn into separate sections---basically chapters, plus two loose
5 pieces that can be configured to go in different places. This
6 allows GNU m4 to preprocess the manual without coredumping.
8 * Makefile.dist: tell TeX where to find texinfo.
10 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
12 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
13 the new target "rdl-apps.texinfo" which captures the Makefile
14 variable that records where to find the Readline libraries.
16 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
18 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
19 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
20 * defs.h (const, volatile): Only define if not already defined.
21 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
23 * README: Update for release 3.95.
24 * config.gdb: Don't create readline dir in subdir builds.
25 * main.c: Include with "..." form for non-system include files,
26 so "gcc -MM" for "make depend" works.
27 Include readline files with "...h" rather than <readline/...h>.
28 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
30 * coffread.c: Undo minor damage done by Rich Pixley. Use
31 different internal and external representations of COFF
32 data structures. Use new BFD routines for swapping them in and
34 * symfile.c (free_named_symtabs): Avoid freeing file names that
35 are null or empty. Old i960 tools seem to produce files that
36 claim to have empty names, causing each successive file read
37 to blow away the previous one.
38 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
39 Move deferred_stores to top of file, but don't separate its
40 #define's from its variable. Add commentary.
41 * Makefile.dist: Fix Rich damage; undo "configure" changes in
42 favor of keeping the (working) config.gdb. Move readline
45 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
47 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
49 * infptrace.c (fetch_registers): no result, since now void.
50 * tconfig/news: target depends on m68k-tdep too.
52 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
54 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
57 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
58 applied various small fixes due to or inspired by RMS comments
60 * doc/gdb.texinfo: finished using all RMS comments, save those for
61 appendices on readline and cmd history (which are in other source
64 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
66 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
67 chapter 9; (2) documented 'break' command's menu mode for
68 overloaded names, in response to hgs problem report C++ p-31
70 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
72 * doc/gdb.texinfo: (1) better introductory example; (2) more
73 consistent use of @code, @samp, @file, @kbd throughout; small
74 cleanups to first three nodes; (3) new "Contributors" node;
75 (4) Appendix, Renamed Commands; (5) divert specialized startup
76 instructions to "Targets" chapter for generic manuals, while
77 leaving them up front for manuals specific to specialized
78 environments; (6) apply fixes from RMS comments through chapter 4.
80 * pretex.m4: modify explanatory text slightly (and redefine
81 "regexp") to keep GNU m4 from complaining. (It still crashes
82 later, but one step at a time...)
84 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
86 * readline/readline.c (update_line): Avoid dereferencing a pointer
87 before comparing it to its bounds. Saber caught this.
88 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
89 and only set PC if tgetstr returned non-null. Saber caught this.
91 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
93 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
94 stuff for config manual) here where it counts; updated
95 to use new subdir structure (gdb/doc/).
97 * Makefile: generated from above via
101 * gdbint.texinfo: added instructions on generating gdb.info* files
102 locally for release. These are ordinary info
103 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
104 Makefile)---but due to use of texinfo 2, can't count on makeinfo
105 to generate these, so we distribute them already formatted.
107 * gdb.texinfo: included full Info node and menu crud (as generated
108 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
110 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
111 put in comments-for-future gdb.info target (one day makeinfo will
114 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
116 * gdb.texinfo: Updated to include new or old undocumented
117 commands, at least the following (perhaps some others I forgot to
118 record): info f, info float, info path, info program, info s, info
119 set, info source, info terminal, info types, info user, set/show
121 Also covered all recent GDB command renames for v4.
123 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
125 * mipsread.c: Rather than keeping count of how many symtabs
126 and psymtabs we have, for sorting purposes, count them when
127 we need to sort. This fixes bug in rereading of symbol tables.
129 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
131 * infcmd.c: renamed "info path" to "show paths"

146 symtab.h, target.c, target.h: Lint.
147 * core.c: setup and select frame after reading shared libs,
148 else reading shared libs will clobber them. Lint.
149 * utils.c (error): Force out any buffered wrap text.
151 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
153 * remote.c: Remove decls of memory_insert_breakpoint
154 and memory_remove_breakpoint, no longer used. (Suggestion of
157 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
158 to make it easier to interface to "configure"'d libraries.
160 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
162 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
163 aliases for set/show print.

609 before we compile it.

661 * values.c: Rename value_history_info to show_values.
662 (_initialize_values): Rename "info values" to "show values".
664 Sun Apr 14 23:08:34 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
666 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
667 New function to give correct error message.
669 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
671 * target.h: Add to_doc and target_preopen.
672 target.c: Add target_preopen and target_command.
674 (add_target): Call add_cmd and mess with targetlist->doc.
675 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
676 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.

699 * symfile.c (clear_symtab_users_once, cashier_psymtab,
700 free_named_symtabs): Move these routines from symmisc.c.
701 * symmisc.c (same): same.
702 (free_symtab): Make non-static.
703 * symtab.h (free_symtab): Declare as exported void fn now.
704 * dbxread.c (end_symtab, end_psymtab): Change comments.

709 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
711 Permit symbols to be superseded when new symbol files have
712 been read in, particularly for VxWorks.
714 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
715 to the main file, as well as to include files. Also, put global
716 functions into the global psymtab, to make "i fun" work.
717 (end_psymtab): Free named symtabs and psymtabs for a file, once a
718 new psymtab for it has been read.
719 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
720 a file, once a new symtab has been read for it.
721 * mipsread.c: FIXME. We need to do the same for MIPS, but it
722 looks harder to determine the top-level block before it's been
723 queued to the psymtab list.
725 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
726 If we have wiped out any old symbol tables, clean up at end of
728 (symbol_file_command): Don't reference symfile_fns if it's zero.
730 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
731 defines for the blocks of a blockvector that contain global and
732 file-static symbols and the first of the smaller scope contours.
733 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
734 decode_line_1, make_symbol_completion_list): Use the above.
735 * coffread.c (end_symtab, patch_opaque_types): Ditto.
736 * dbxread.c (end_symtab): Ditto.
737 * expread.y (block): Ditto.
738 * mipsread.c (throughout): Ditto.
739 * symmisc.c (free_named_symtabs): Ditto.
741 * symtab.c (list_symbols): Process the first symbol of the
742 static psymbols list.
743 (types_info): Restore this function from its untimely #if 0.
744 It's not perfect, but it is better than nothing.
745 (_initialize_symtab): Restore "info types".
747 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
749 * m68k-stub.c: Remote stub for 680x0's, created from
750 rem-m68k.shar (which is removed).
751 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
752 Remove RCS log stuff now that we use CVS and it blows our diffs.
754 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
756 * symmisc.c (free_named_symtab): Make it work, in its current
757 kludgy fashion. Change result to indicate if we blew away bkpts.
758 * dbxread.c (end_symtab): Accumulate result from
759 free_named_symtab and print warning if we blew user's state.
760 * symfile.h: free_named_symtab now returns an int.
762 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
764 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
765 is the first symbol read, even if not mainline.
766 (dbx_psymtab_to_symtab): symfile might be zero, cope.
767 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
768 (set_section_command): New command ("section xxx yyy" -- should
769 be renamed to "set section xxx yyy" FIXME) which sets the
770 base address of a section of the exec file, overriding the
771 virtual address that BFD reports.
773 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
775 * exec.c: Add add_syms_addr_command to exec_ops, so you can
776 load symbols at any address while examining an exec file.
778 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
780 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
781 for printing the float info is host-dependent, not
782 target-dependent. FIXME.
783 * i386-pinsn.c: Move #includes to top, remove useless ones.
784 * i386-tdep.c: Don't bother including <.../reg.h> since we
785 don't use it (and it doesn't exist on host systems).
787 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
788 Convert negative numbers properly.
789 (ieee_test): Make numbers really random; fix format arg.
791 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
792 * core.c (core_detach): Unpush core_ops, which might not be on
793 top. We used to just pop the top, which broke things. Don't
794 need dont_repeat() any more.
795 (core_file_command): Psst! Don't repeat it.
796 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
797 * expprint.c (print_subexp): Avoid switch fallthru on
798 BINOP_ASSIGN_MODIFY, so we can print += and such.
800 * inflow.c (kill_command): After killing inferior, print our
801 current frame in the core file, if we have one.
802 (generic_mourn_inferior): When inferior dies, either select
803 the current frame (in the new target, e.g. core file), or
804 set both the current and selected frames to NULL.
806 Changes from Peter Schauer.
808 * infptrace.c: Avoid <sys/ptrace.h> on USG.
810 * Make all file names fit in 14 characters (sigh and damn!):
811 mv hp300hpux-xdep.c hp300ux-xdep.c
812 mv symmetry-xdep.c symm-xdep.c
813 mv symmetry-tdep.c symm-tdep.c
814 mv convex-opcode.h convx-opcode.h
815 mv tm-vxworks960.h tm-vx960.h
816 mv tm-vxworks68.h tm-vx68.h
817 mv Makefile.srcdir Makefile.sdir
818 mv gdb-int.texinfo gdbint.texinfo
819 mv remote-sa.m68k.shar rem-m68k.shar
820 mv remote-multi.shar rem-multi.shar
821 * Makefile.dist, README, config.gdb, convex-pinsn.c,
822 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
823 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
826 * command.c (user_info_1, user_info): New command for listing
827 the user-defined commands.
829 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
831 * dbxread.c (really_free_pendings): Clear file_symbols
832 and global_symbols after freeing them; otherwise, running
833 this function twice (if it appears twice on the cleanup
834 chain), we try to free things twice.
836 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
837 based on text_addr (the address of text in core), not on addr (the
838 offset between text in the .o file and in core). This change
839 is from Peter Schauer.
841 * main.c: Define ALL_CLEANUPS as a cast of zero.
842 (return_to_top_level): Use it.
843 (main): Do all cleanups after each command run as part
844 of the gdb startup sequence. Also do all cleanups before
845 entering the command loop, and every time we exit the command
846 loop and reenter. Before, the cleanups from the startup sequence
847 were being left undone until the first error!
848 (command_loop): Rename do_nothing cleanup to command_loop_marker
849 so we can see it easily when examining the cleanup chain.
850 (init_signals): Add another do_nothing for signal handling.
851 (quit_command): Only try to kill target if it has execution.
852 Problems in the target stack got us into a state where
853 inferior_pid was nonzero but none of the targets had execution.
854 In this state you couldn't exit gdb.
856 * dbxread.c: Two changes from Peter Schauer.
857 (echo_command): Fflush output after an echo command.
858 (show_history): Pass all args to cmd_show_list.
860 * utils.c (init_malloc): Call mtrace to turn on tracing
861 if the environment variable MALLOC_TRACE is set to a file name.
862 * mtrace.c: Add source file which provides a log of every malloc,
863 free, and realloc to a trace file.
864 * mtrace.awk: Add source file which analyzes the trace file.
865 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
866 (VERSION): Roll to 3.94.3.
868 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
869 (check_duplicates): Don't bother with watchpoints.
870 (set_raw_breakpoint): Comment about danger of this routine.
871 (watch_command): Parse and eval all args before calling
874 * solib.c (find_solib): Avoid error in referencing memory to
875 see if any more shared libraries have been added. This is
876 particularly useful if the target has terminated. Bug reported
879 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
880 in bringing up 3.94.2 on the Sun-3.
882 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
883 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
884 expression (in scope) before reenabling watchpoint.
885 * signame.c (init_sigs): Add missing declaration of i, fix
886 sys_siglist declaration.
887 * source.c (list_command): Fixed range computation to use
889 * stack.c (backtrace_command): Do not allow command if target has
890 no stack, print informative error message.
891 * target.c (target_command): Do not write into command line
892 because this fails if the target command is used in a user defined
893 command. [This change was enhanced by gnu to support any-
894 unique-prefix matching on target names.]
895 * valops.c (value_struct_elt): Avoid infinite loop on an
896 erroneous attempt to print the member of function (try p main.p).
898 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
900 * expread.y (name_no_typename): Avoid reduce/reduce errors
901 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
902 Since the GDB parser really doesn't use name_no_typename in a
903 name-only context, the parser can't tell the diff between
904 names and numbers here. Avoid allowing a name_no_typename
905 to be a NAME_OR_*INT to resolve the conflict.
907 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
909 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
911 * valprint.c (val_print_fields): bitfield printing didn't handle
912 byte order. Indirect through a few more fns to cope.
914 * values.c (modify_field): also cope with byte order.
916 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
918 Cleanup for release 3.94.2:
920 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
921 include files. Roll version to 3.94.2.
923 * coffread.c (init_stringtab): Read length into unsigned char
924 array before swapping; don't assume 32-bit longs.
926 * target.c (target_info): Don't bother with get_sym_file, just use
927 the symfile global variable.
928 * symtab.h, symfile.c (get_sym_file): Delete it.
930 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
931 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
932 (read_type): Replace one more error() with complain().
934 * mipsread.c (parse_partial_symbols): Replace printf with complain.
936 * i960-tdep.c: Fix copyright attribution.
938 * config.gdb: Quote all backquotes in doublequotes. You can
939 quote me on that. BSD 4.4 shell found this one.
941 * infptrace.c (throughout): The third argument to ptrace is an
944 * infrun.c (wait_for_inferior): When program has terminated, we
945 have to call target_terminal_ours before we pop that target off
946 the stack (e.g. before a call to target_kill or
947 target_mourn_inferior). This fixes problem where a program
948 terminates, then GDB stops for (tty output) and you have to type
949 "fg" to the shell to resume it. FIXME: This code for what to
950 do after termination really should be in normal_stop instead.
952 * gdbcore.h (read_memory_check): Change declaration; it changed
955 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
956 4.4 prereleases, this avoids a bug in their sgtty compatability
958 * remote.c: Use terminal.h rather than hand-rolling the same.
960 * signame.c, signame.h (psignal): Arg is unsigned, not int.
961 * utils.c (strsave, strstr): Fix arg types.
962 * valprint.c (val_print): lint
964 MIPS symbol table support from Per Bothner:
966 * symfile.c (symtab_fns): Remove initializer table that needs to
967 be hacked for each new symbol file format supported.
968 (add_symtab_fns): New function, chains symbol table
969 handlers into the global list.
970 (symfile_init): Search this list.
971 * symfile.h: Add next pointer, declare add_symtab_fns.
972 * coffread.c (_initialize_coffread): Call add_symtab_fns.
973 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
975 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
976 symbol *). Thus, we no longer need the hack to trash
977 pst->filename. Good, since that hack confused code in symfile.c!
979 (reorder_symtabs, destroy_all_symtabs): Removed static
980 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
981 Instead, the latter now uses a temporary array (stack-allocated
982 from an obstack, and then freed).
984 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
985 haven't been set in the outermost stBlock of a procedure. This was
986 a problem with f77 binaries on Ultrix 4.?.
988 (new_symtab, new_symbol, new_type): Continue changing code to use
989 obstacks more and otherwise conform to dbxread internal style.
990 Made the free_code of symtabs be free_linetable (as in dbxread)
991 instead of free_contents. This implies memory leaks when reading
992 a new symbol table, until the conversion is finished. Did change
993 (struct symbol) and (struct type) to be allocated on the
994 symbol_obstack. Blocks and blockvectors are among the things
997 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
998 tested much, but it solved one problem (reported by Meissner), and
999 cleans up some other things. The problem happened when an
1000 included file contains actual code (functions) and not just
1001 definitions. The mips coff is a little inconvenient there, since
1002 it may cause a procedure to be mapped to the wrong psymtab.
1004 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1005 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1006 this will need work for the new core paradigm.
1008 Opcode patches from the net:
1010 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1011 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1012 missing altogether - they are added here. From Bruce Bauman.
1013 * mips-opcode.h: The low mask for C0 instructions was too small.
1014 From Garrett Lau. I modified the fix to check the entire 32-bit
1017 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1020 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1022 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1024 * dbxread.c (read_type): Pointer subtraction (value_sub in
1025 valarith.c) sometimes failed because the types of the
1026 pointers being subtracted were not identical.
1027 These differed because dbxread.c was allocating pointer types
1028 using dbx_alloc_type+smash_to_pointer_type instead of
1029 lookup_pointer_type. I failed to find a justification for the
1030 former, so I changed it to use the latter. Similarly, I
1031 replaced smash_to_function_type by lookup_function_type,
1032 and smash_to_reference_type by lookup_reference_type.
1034 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1035 _initialize_mipsread): corresponding changes.
1037 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1039 * source.c (mod_path): Do tilde_expand on each component of the path,
1040 rather than on the (list of) paths as a whole.
1041 (print_source_lines): Set first_line_listed in addition to
1042 current_source_symtab and current_source_line. If the source was
1043 not findable, after a "dir" command to fix the problem,
1044 a "list" would get the wrong lines.
1046 While I was there... (gnu):
1048 * dbxread.c (read_type): Change error to complaint.
1050 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1052 First attempt at detailed understanding of symbol table memory alloc.
1054 * dbxread.c (dbx_symfile_read): Free our string table if we
1055 aren't the mainline. Free the "info" struct since we're done with
1057 (init_psymbol_list): Free any previously allocated psymbol lists.
1058 (): FIXME: Should realloc-down the psymbol lists when done reading
1059 the main symbol file?
1061 * symmisc.c (free_symtab): Free fullname field too.
1063 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1064 (REGISTER_ADDR): Make result type unsigned int.
1066 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1067 define REGEX must also define REGEX1 (its dependency).
1069 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1071 * tconfig/i960: No longer works, points you at vxworks960 or
1074 * xgdb.c, XGDB-README: Remove file. Users can get the much
1076 * Makefile.dist: Remove all trace of xgdb.
1078 * breakpoint.c (breakpoint_1): Pass demangle arg to
1079 print_address_symbolic.
1080 (clear_breakpoints): Remove unused function.
1081 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1082 (breakpoint_re_set): Use catch_errors to do them all anyway.
1084 * gdb-int.texinfo (Host versus Target): Add section on what is
1085 a "host" feature versus what is a "target" feature.
1087 * infcmd.c (path_command, path_info): Handle the PATH variable
1088 (object search path) as conveniently as the source search path.
1089 * environ.c (set_in_environ): Set some vars in GDB's environment,
1090 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1091 * source.c (mod_path): New function, from guts of
1092 directory_command, modifies a path. Used by path_command.
1093 (directory_command): Call it.
1094 * defs.h (strsave): Declare.

1097 (printchar): Use it.
1098 (strsave): Provide this handy helper routine.
1099 (set_width_command): Rename set_screen_width_command.
1100 (_initialize_utils): "set screen-width" => "set width";
1101 "set screen-height" => "set height"; add sevenbit-strings.
1103 * infcmd.c (do_registers_info): Print floating point registers
1104 in raw hex as well as float format, regardless of whether it is
1105 a "virtual" convertible register.
1106 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1107 regs as a double, just in case it's being used that way.
1108 * values.c (unpack_long): Comment on array/function coercion.
1109 (unpack_double): Argument is in target byte order now. For
1110 integer arguments, just call unpack_long and float the result.
1111 * m68k-tdep.c: include defs.h for "const" handling.
1112 * remote-nindy.c: Use ieee-float stuff.
1113 (nindy_fetch_registers): Unpack double regs to host double, then
1115 (nindy_store_registers): Pack extendeds to host double, flip
1116 around by misusing unpack_double, send as target double.
1118 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1119 zero, as when stopped at the first instruction of a process.
1121 * blockframe.c: Fix filename in comment (param.h => tm.h).
1122 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1123 * tm-68k.h: Fix typos.
1125 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1127 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1129 * coredep.c (fetch_core_registers): Pass end-address of register
1130 section to register_addr as expected. Don't call supply_register
1131 if we'd just pass it garbage.
1133 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1135 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1137 * target.c (push_target, target_info): Cast enums to int for < or
1140 * stack.c (print_frame_info): Identify source file & line
1141 even if we can't print it.
1143 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1145 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1147 Clean up IEEE floating point support.
1149 * ieee-float.h: New file.
1150 * ieee-float.c: Write real routines to convert between host
1151 doubles and various target IEEE extendeds.
1152 * m68k-xdep.c: Eliminate assembler code for extended floats.
1153 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1154 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1155 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1156 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1157 double_to_ieee_extended.
1158 * i960-tdep.c: Define ext_format_i960.
1159 * m68k-tdep.c: Define ext_format_68881.
1160 * sparc-tdep.c: Define ext_format_sparc, though unused.
1161 * Makefile.dist (HFILES): Add ieee-float.h.
1162 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1165 Obsolete the "coffstrip" program in favor of using BFD's strip.
1167 * nindy-share/coffstrip.c: Remove file.
1168 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1169 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1170 * tconfig/nindy960: Remove reference to coffstrip.o.
1172 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1174 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1176 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1177 * dbxread.c: Remove static symfile_bfd.
1178 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1180 * inftarg.c (child_detach): Pop the child_ops vector if the
1181 detach is successful.
1182 * remote-nindy.c (nindy_create_inferior): Don't push a new
1183 nindy_ops since nindy uses the same one for execution and memory
1185 * core.c (core_ops): Use child_attach and child_create_inferior
1186 rather than default attach and create_inferior functions.
1188 Handle floating point registers in core files.
1190 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1191 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1192 This version untested since BFD doesn't yet support sun3 core
1194 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1195 conventions. Fix comments and style. This version has not
1196 been compiled yet, since we have no HP inhouse.
1197 * core.c (get_core_registers): Look for two sections, ".reg"
1198 and ".reg2", and pass both to fetch_core_registers sequentially.
1200 Revise directory path yet again.
1202 * source.c (forget_cached_source_info): Not static any more.
1203 (init_source_path): New default source path is "$cdir:$cwd".
1204 (dir_command): Handle variable arguments ($cdir, $cwd).
1205 (source_info): Print "Compilation directory" rather than
1206 "Originally compiled in" to remind people of $cdir.
1207 (openp): If the path contains $cwd, use current directory.
1208 (open_source_file): If compilation directory is known, replace
1209 first $cdir in path with the compilation directory.
1210 (print_source_lines): Even if we can't print the lines, set the
1211 current symtab and line for future commands like "info source" or
1212 "breakpoint". Also, error message now contains the file name,
1213 line number, and file access error message.
1214 (_initialize_source): Fix help text to describe changes.
1215 * main.c (cd_command): Forget cached source info when we chdir.
1216 * utils.c (strstr): Add simple implementation.
1218 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1220 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1221 Byte-swap COFF symbol tables if necessary when reading them in.
1222 Use complain() to replace error message in one spot. Needs
1223 corresponding change in bfd/coff-code.h to make some symbol
1224 swapping routines non-static.
1226 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1228 Merge changes from Eirik Fuller, for UTek.

1232 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1233 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1234 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,

1236 declarations of errno.
1238 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1240 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1241 <rpc/rpc.h> and <rpc/types.h>.
1243 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1245 * i960-tdep.c (examine_prologue): Add new argument limit,
1246 which stops the scan at the end of the prologue, or at the PC.
1247 This fixes a problem where it walks down into the code for the
1248 user's statements if that code looks like function prologues.
1249 Mark Fox and I have been bouncing this code back and forth, making
1250 small changes to it. Callers changed to match.
1252 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1254 Cleanup for gdb-3.94 release final:
1256 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1257 the .c files from vx-share and nindy-share, from the various
1258 macros, since they are not found via ALLDEPFILES.
1259 (SFILES): Add tm-i960.h.
1260 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1261 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1263 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1264 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

1268 * am29k-tdep.c: Add contribution line.
1269 (examine_prologue): Cache information about function prologues in
1270 the misc-function-vector to avoid lots of references over the
1271 serial line while examining instructions.
1273 * core.c (core_close): New function made from cleanup_core.
1275 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1276 remote-vx.c, remote.c, target.c, target.h,
1277 Update target_ops vector to add attach, close, and load entries.
1278 Use add_syms_addr_command, not add_file_addr_command, for
1279 add_file. Break out close routine from existing code.
1281 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1282 they are in an obstack.
1283 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1285 (define_symbol): Add symbol type parameter; change callers;
1286 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1287 it to influence the symbol class on the i960.
1288 (define_symbol): Swap LOC_CONST's into target byte order.
1290 * exec.c (exec_close): New function.
1291 (exec_file_command): Call it.
1293 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1294 Fix byte order of frame pointer.
1295 (read_var_value): Result of 0 if var's value can't be found,
1296 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1297 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1298 (locate_var_value): Use read_var_value and use its lazy address
1299 as the location of the var's value. Lint.
1301 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1304 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1305 obsolete Intel versions in favor of vxgdb versions.
1306 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1307 code dealing with byte order of values, which Intel did in host byte
1308 order rather than gdb-4's target byte order.
1309 (i960_frame_chain_valid): Move to nindy-tdep.c.
1310 (examine_prologue, skip_prologue, frame_find_saved_regs,
1311 frame_args_address, leafproc_return, saved_pc_after_call,
1312 pop_frame): Add vxgdb versions from Mark Fox.
1313 (examine_prologue, frame_struct_result_address): Add code
1314 to deal with the saved value of G13 (struct return address
1316 (frame_args_address): Modify Mark's version to prefer the
1317 saved value over the current value in the topmost frame.
1318 Cache result in the frame info to avoid performance hair in
1320 (print_fault): Add gdb960 code for printing faults.
1321 (_initialize_i960): Actually call check_host.
1323 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1324 add stub routines. FIXME, these currently just return zero!
1326 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1327 (attach_command): Call target_attach, not target_open, now.
1329 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1330 (child_attach): Rename from child_open.
1331 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1332 don't confuse it with a zero step_resume_break_address.
1334 * inftarg.c (child_detach): Eliminate inferior_pid test.
1335 (child_files_info): Clean up message a bit.
1336 (child_ops): Use child_attach, not child_open, to attach.
1338 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1339 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1340 findvar.c to here, since it depends on the contents of the
1341 shadow_contents of breakpoints, but keep if #if 0 since it is
1344 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1347 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1348 (ptype_command, display_command): Eliminate have_inferior_p and
1349 have_core_file_p in favor of target_has_stack or
1350 target_has_execution.
1351 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1352 code for actually finding the values of arguments, though we still
1353 keep track of the maximum stack offset for use in printing unnamed
1354 arguments. Handle missing FRAME_ARGS_ADDRESS.
1356 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1357 (struct nindy_regs): Define registers passed to/from nindy.
1358 (nindy_fetch_registers, nindy_store-registers): Translate between
1359 nindy and GDB formats for the registers.
1360 (dcache_init): Statically allocate the cache, since it was being
1361 allocated by a malloc that was never freed anyway.
1362 (nindy_create_inferior): Error, not core dump, if no exec file.
1363 (nindy_before_main_loop): Use target_load, not target_add_file.
1365 * remote-vx.c (net_load): Specify large timeout for load
1366 requests. Allow user to break out with INTERRUPT.
1367 (net_break): Remove useless code, clean up. Change callers.
1368 (parse-args, skip_white_space, find_white_space): Clean up arg
1369 parsing to cope with quoted strings.
1370 (net_wait, net_quit): Never call error, just return status.
1371 (vx_read_register, vx_write_register): Cleanup status checking.
1372 #ifdef the code based on which CPU we are using (960 or 68k),
1373 FIXME, this should be completely general but it isn't yet.
1374 (vx_xfer_memory, vx_resume): Cleanup status checking.
1375 (vx_run_files_info): Improve message.
1376 (vx_load_command): Renamed from vx_add_file_command. Allow load
1378 (net_ptrace): Remove unused routine.
1379 (vx_wait): Adopt code from vxgdb960 to cope with broken
1380 connections to target machine and prompt to disconnect. Remove
1381 debug printouts. Map some EVENT_'s to SIGnals.
1382 (add_symbol_stub, vx_open): Print names of object files we found,
1383 and "ok" if we read their symbols OK. Clarify output in general.
1384 (vx_attach, vx_detach, vx_kill): Add these commands.
1385 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1386 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1387 "info files" output, and create_inferior, since we already have
1390 * stack.c (frame_info): Replace Frame_unknown with 0.
1391 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1392 (return_command): Pop until the PC matches as well as the FP,
1393 so it works even if the FP is shared with another function,
1394 as in "frameless" or "leaf" procedures.
1396 * symfile.c (load_command): renamed from add_file_target_command.
1397 (add_syms_addr_command): renamed from add_file_addr_command.
1398 (add_syms_command): Stub to call target_add_syms.
1399 (_initialize_symfile): Change command names and descriptions,
1400 add-file => add-syms, and load from alias to its own command.
1402 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1403 maybe_kill_then_create_inferior): Default for attempts to start
1404 a process, if one is already running, is to ask about killing
1405 it and retry if yes.
1406 (upstack_create_inferior): #if-0 it, strata obsolete it.
1407 (push_target, unpush_target, pop_target): to_close() a target
1408 before unstacking it.
1409 (target_info): Renamed from target_files_info.
1410 (_initialize_targets): Rename "i files" as "i target", accessible
1413 * target.h: Improve comments about the target_ vectored routines.
1415 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
1416 Convert commenting style to standard GNU style.
1417 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
1418 (SKIP_PROLOGUE): No longer a no-op.
1419 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1420 (*_REGNUM): Sort register numbers.
1421 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1422 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1423 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1424 are now 10 byte extendeds, not 8 byte doubles.
1425 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1426 for nindy versus vxworks targets. FIXME, this should possibly go
1427 in the target vector.
1428 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1429 frame_saved_regs and arg pointer with each frame.
1430 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1431 (FRAME_ARGS_ADDRESS): Use cached result.
1432 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1433 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1434 (PRINT_RAMDON_SIGNAL): Call print_fault.
1435 (POP_FRAME): Now works.
1437 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1438 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1439 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1440 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1443 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1444 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1446 * valarith.c (value_subscripted_rvalue): Avoid handling
1447 floats and doubles specially; it gave alignment errors. Lint.
1449 * valops.c (value_of_variable, value_of_this): Error if unknown
1452 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1453 to avoid alignment problems.
1454 (value_print): Handle unknown value address.
1455 (cplus_val_print): Two args are ignored; remove them. Change caller.
1456 (val_print): Use unpack_long rather than pointer-deref.
1459 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1460 to avoid alignment problems.
1461 (value_being_returned): Error if return value unknown.
1462 (set_return_value): Add bogosity warning, FIXME. *
1464 * TODO: A woman's work is never done.
1466 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1467 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1468 Add ieee-float.o to OBS.
1469 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1470 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1471 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1473 Changes to generalize the VxWorks RPC protocol slightly, to handle
1474 i960 as well as 68000.
1476 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1477 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1478 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1479 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1480 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1481 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1482 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1483 so they will move in target byte order rather than network
1484 byte order (happens to be the same).
1486 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1488 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1490 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1493 Add contribution lines to various files, showing where they
1496 * breakpoint.c (break_insn, check_break_insn_size,
1497 read_memory_nobpt): Remove to mem-break.c.
1499 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1502 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1503 entry has bad register number. This change is not
1504 tested in this release, FIXME.
1506 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1509 * value.h: Force value's contents field to be aligned to hold
1510 at least a double or a long long (if supported). This avoids
1511 doing bcopy's in and out of the contents field.
1513 (step_1): Avoid coredump under obscure circumstances when we
1516 * symtab.h (misc_info): Add field to misc function vector for
1517 any kind of cached information the target code desires. AMD
1518 29000 uses this to avoid repeating examine_function_prologue's.
1520 * coffread.c: Lint. Remove static symfile, read_section_header.
1521 core.c (have_core_file_p): Lint: remove.
1522 expprint.c (print_subexp): Lint.
1523 infptrace.c, valops.c, valprint.c: lint.
1525 Roll in changes from vxgdb-5.0.1:
1527 * symtab.h: Comment byte order of each address class. Add
1528 LOC_LOCAL_ARG for frame-relative args (960).
1529 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1530 symtab.c, symmisc.c: ditto.
1532 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1534 * remote.c (remote_resume): Error if resume with a signal.
1536 * symfile.c (prim_record_misc_function): Clear misc_info.
1537 (fill_in_vptr_fieldno): Check stub type of arg.
1539 * valops.c (value_cast): Avoid looking up names of types whose
1540 name we don't know, to prevent coredump. Sun CC produces typedef
1541 rtx and the name of *rtx is zero...
1543 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1545 Roll in changes from final AMD 29000 port (Tiemann).
1547 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
1548 for ../include/a.out.encap.h. This might not work now that BFD
1549 is separately compiled. Instead, BFD support for encap will have
1550 to translate machine type 29k into the right COFF_MAGIC.
1552 * infcmd.c: Remove references to inferior_pid that aren't used
1553 in actual ptrace calls; use target_has_execution, etc.
1554 (have_inferior_p): Remove function.
1555 (program_info): Print target info rather than "process number";
1556 avoid gratuitous messages unless from_tty.
1557 (run_stack_dummy, finish_command): Set proceed_to_finish.
1558 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
1559 main.c: Lint. Lose have_inferior_p().
1560 inferior.h (have_inferior_p): Remove, lint.
1561 (proceed_to_finish): Add flag to ask that all regs be saved
1562 by normal_stop, for the few commands that need it, speeding up
1563 serial I/O. Add comments to stop_registers.
1565 * remote-eb.c: Remove newline from breakpoint message we grep
1566 for. Never time out when running the user program.
1570 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1572 Roll in changes from vxgdb-5.0.1:
1574 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
1575 symbol in its raw form, we are processing an unlinked ".o" file.
1576 See if the target environment has assigned it an address, using
1577 target_lookup_symbol (VxWorks does), and enter it into the symtab
1580 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
1581 68k versions for a simpler version that assumes zero FP at bottom.
1582 Fixes bug of truncated stack reports.
1584 * target.h (target_lookup_symbol): Define this routine's args
1585 and result, finally.
1587 * target.c (nosymbol): Default routine for target_lookup_symbol.
1588 (target_default): Default lookup_symbol and call_function too.
1589 (files_info): Only print has_all_memory warning if a non-dummy
1592 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
1593 vx_convert_from_virtual): If target does not have floating point,
1594 zero register "values", and avoid doing cross-net conversions.
1595 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
1596 (vx_open): Rearrange code that attaches to target and reads
1597 symbols for all loaded modules, to work if some of the modules
1598 are not accessible. Add symbol_stub() and add_symbol_stub()
1599 as callbacks from catch_errors(). Allow connect attempt to be
1600 interrupted painlessly with ^C (FIXME, there are still some bugs
1601 if the interrupt happens during symbol reading.). Print
1602 final message with puts_filtered, since symbol messages are
1607 * main.c (catch_errors): Only print errstring if non-null.
1608 (command_loop): Avoid an ioctl per command to test ISATTY.
1610 * remote-vx.c (net_load): make static; avoid sophomoric msg.
1611 (vx_xfer_memory): Return correct result!
1612 (vx_files_info): Indicate whether target has float or not.
1613 (vx_lookup_symbol): Complain, not error, if target gone.
1614 (vx_open): Print "Connected" msg before disabling immediate-quit.
1615 [FIXME: lookup_symbol and vx_open changes need testing.]
1617 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
1618 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
1619 contributor lines and update copyrights to 1991.
1621 Changes from an attempted H-PUX host port:
1623 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
1624 defines PT_ATTACH and PT_DETACH but not PT_KILL.
1625 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
1626 * remote-vx.c: include <sys/time.h> for HPUX.
1627 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
1628 "core_file_command" routine to BFD regime. May not work yet.
1630 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
1632 * xgdb.c: Replace X10 version with some VJ version.
1633 (FIXME: Its copyright assignment is not on record.)
1634 * xgdb.c: Update include files to X11R4 (Xaw crud).
1635 (xgdb_display_source, create_text_widget): fix call to
1636 get_filename_and_charpos. Rewack source window stuff for X11R4
1637 (gleaned from include files, and "nm's" of binary libraries, since
1638 I had no doc available).
1639 (append_selection, append_selection_word): Disable with FIXME
1640 since R4 changed interface here.
1641 (create_buttons): Add back the old set of buttons.
1642 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
1644 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
1645 Roll VERSION to 3.94 (not yet final though).
1647 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1649 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
1650 obstack_int_grow, obstack_int_grow_fast): Eliminate
1651 cast on left of assignment, which gives MIPS cc fits and is
1654 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
1655 F_ALIAS. Use printf, not fprintf, when not passing a file
1657 (compare_opcodes): Check that identical instructions have
1658 identical opcodes, complain otherwise.
1660 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
1661 was reported by Roland McGrath.
1662 (unimp): Only match if exactly zero instruction. (Roland)
1663 (branches and traps): Generate all variations of these
1664 instructions with macros, based on a single call that defines
1665 each condition name and its binary representation.
1666 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
1668 * valprint.c (val_print_fields): Take, and use, format parameter.
1669 This means that "p/x struct" again prints the elements in the
1670 desired format. Changed callers.
1672 * stack.c (frame_info): Use filtered output, and indicate wrap
1673 points. Remove kludgy formatting designed to avoid line wrap.
1675 * utils.c (wrap_here): If the line is already full (because
1676 we had printed a long indent or long wrapped string), do an
1677 immediate newline-and-indent.
1679 * m68k-pinsn.c (print_insn_arg): Bugfix from
1680 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
1681 instruction is incorrectly disassembled as bkpt #8.
1683 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
1684 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
1685 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
1686 and then will dump core (sometimes). I traced it back to an
1687 uninitialized symfile_name in psymtab_to_symtab.
1688 (const_vol_complaint): Add quotes to message.
1689 (define_symbol): Only believe line number if gcc_compiled.
1690 Avoid allocating symbol if we will not return it.
1692 Add target strata support so that newly established targets go
1693 into their right place in the target stack (e.g. a new exec file
1694 doesn't wipe out the ability to access the running process).
1696 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
1697 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
1698 and initialize it properly in all the targets.
1700 * target.h: Document strata. Change return type of push_target.
1702 * target.c (nomemory): new function for dummy memory access.
1703 (tcomplain): Rename complain, now also used in symfile.c.
1704 (push_target): Push targets within strata. New return value shows
1705 whether new target is on top of stack or not. Always keep dummy
1707 (target_files_info): Ignore dummy target.
1709 * core.c (core_open): Warn user, and skip accessing file, if the
1710 core target is not the topmost target in the stack.
1711 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
1714 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
1715 target_ops, it doesn't belong there since we have no regs there.
1716 Change name of target from machine => memory to clarify.
1718 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
1720 * Freeze version 3.93 for release.
1722 * Makefile.dist: Handle vx-share and nindy-share subdirs
1723 properly when building gdb.tar.Z.
1725 * symtab.c: lint; add no_symtab_msg to consolidate the messages
1726 printed in various places, so I could change just one copy.
1728 * dbxread.c, coffread.c: Change references to bfd->iostream
1729 to cast to FILE *, now that BFD avoids needing types defined
1730 in other header files.
1732 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1734 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
1735 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
1736 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
1737 (actually gcc -Wall).
1739 * dbxread.c: Remove first_global_sym, last_global_sym, since
1740 they are never referenced.
1742 * defs.h (baud_rate): Declare.
1743 main.c: Define it, and add the -b option to set it.
1745 * gdb-int.texinfo: Add text on how to define a new host or target
1746 architecture, prompted by Per Bothner's questions about MIPS
1749 * gdb.texinfo: Document "complaints". Change doc of -q since
1750 gdb no longer prints the copyright and blurb if you specify a file
1751 name to be debugged (just like Emacs). Add doc for Nindy-specific
1752 command line flags for specifying target serial port and such.
1753 Update copyright to 1991.
1755 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
1756 has taken over for us the job of ripping up executable files. The
1757 crud caused Per Bothner's port to not compile.
1759 * infrun.c (normal_stop): Avoid printing "Program exited
1760 normally" if we are in batch mode. This allows a GDB which
1761 executes a program on a target system, to behave like a Unix
1762 command (input from stdin, output to stdout, no extraneous
1765 * main.c (main): Allow additional machine-dependent command line
1766 options to be specified with the ADDITIONAL_OPTIONS,
1767 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
1768 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
1769 processing to occur just before the main loop with
1770 BEFORE_MAIN_LOOP_HOOK.
1771 (main): If a "core file" argument is specified, and it is not a
1772 core file, try it as a process ID to attach.
1773 (symbol_completion_function): Attempt to cope with
1774 "show screen-" TAB, not very successfully. This needs more work,
1776 (batch_file): New function, returns whether we are reading
1777 commands from an interactive tty on stdin, or from somewhere else.
1778 Called by normal_stop since it doesn't get from_tty passed down
1779 to it like many commands do.
1781 * remote-nindy.c: Handle command line options for nindy
1783 (nindy_before_main_loop): Prompt user for tty name if they
1784 don't specify it before getting to the interactive command loop.
1786 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
1787 and -r command line options. Also add hook before main loop
1788 to make it easy to specify a tty.
1790 * TODO: More things to do, one done.
1792 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
1794 * dbxread.c: Make complaint() calls pass pointer, not struct.
1795 Add complaints about badly formatted C++ type information
1796 (const/volatile indicator, and parse errors resulting in
1797 error_type). Fix C++ virtual member fn comment.
1798 (read_struct_type): Avoid bumping pointer if we got a parse
1799 error; this prevents our walking beyond the end of a string.
1800 Terminate loop on null char as well as semicolon.
1801 (process_one_symbol): Fix the LBRAC fix so that it uses the
1802 last previous SLINE, FUN, or SO record's PC address. C++ debug
1803 symbols did not have SLINE records in a useful order compared
1804 to the LBRAC records.
1805 (define_symbol): Handle "catch" records.
1807 * symtab.c (check_stub_type): Added new complain
1808 `stub_noname_complain' and added a consistency check to
1809 keep the debugger from crashing when finishing from an
1810 exception frame. A real fix will be needed later.
1812 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1814 * infcmd.c (attach_command): Make global.
1816 * Makefile.dist (REMOTE_OBS): Make these compile by default,
1817 but make them easy to comment out. Perhaps later they should
1818 be enabled by what CPU you configure for? FIXME.
1819 (VERSION): Roll to 3.93.
1820 (pinsn.o): Remove rule for obsolete file.
1821 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
1823 Run down a problem that manifested by printing the wrong function
1824 name in stack traces of read_ofile_symtab. Turned out that the
1825 problem was the SunOS 4.1.1 (and previous) C compiler outputs
1826 the LBRAC symbol with an address in the *data* segment, which
1827 blew our binary search through the blocks.
1829 * dbxread.c: Use the complain() facility consistently to bitch
1830 about problems in the symbol file we are reading.
1831 (finish_block): Add code to check the nesting of the blocks;
1832 complain and Procrust them to fit if wrong.
1833 (make_blockvector): Check the order of the blocks, complain
1834 [but don't cope] if wrong.
1835 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
1836 symbols to be sure their PC value is greater than the last SLINE
1837 (line number) symbol we've seen, complaining and adopting the
1838 SLINE PC value if wrong.
1840 * symfile.h (struct complaint, complaint_root, complain,
1841 clear_complaints): Add.
1842 * symfile.c (complain, complaint_root, clear_complaints): Add
1843 facility to deal with non-fatal complaints and to regularize their
1845 (symbol_file_add): Clear complaint counters to allow new complaints.
1846 (initialize_symfile): Add 'set complaints' and 'show complaints'.
1848 * dbxread.c (dbx_symfile_read): Remember the address and size
1849 of the string table for the main symbol file, so we won't read it
1851 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
1852 to avoid reading the string table yet again. Lint.
1853 (throughout): Improve filtered output, including word wrap.
1854 (read_range_type): Improve Bothner's fix to handle other types too.
1856 * utils.c: Improve line wrap implementation. Handle unlimited
1857 width by making chars_per_line unsigned.
1858 (puts_filtered): New, easy, function.
1860 * defs.h (puts_filtered): add.
1862 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
1863 call the identical sort_symtab_syms() in symfile.c instead.
1865 * expread.y: Suggest the `file' command rather than `symbol-file'.
1867 * command.h (enum var_types): Add zinteger for seroable
1869 * command.c (do_setshow_command): Handle var_zinteger. Restructure
1870 nested if's into a switch.
1872 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
1873 we did not stop because of a breakpoint (it must have been for
1874 some other reason, like a "stepi"), so don't print anything.
1876 * symtab.c: Include <sys/types.h> all the time. Now that BFD
1877 doesn't include <sys/types.h>, old SunOS's require it for
1880 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
1882 A test port of gdb-3.92.6 to the Sony NEWS.
1885 Don't normally link in remote- or vx stuff.
1886 Some of it doesn't compile, and it wastes space for 99% of the users.
1887 Remove reference to no-longer-used HAVE_VPRINTF.
1888 Fixed BFD_DEP typo to BFD_DIR.
1890 Fix cast in arg to bfd_h_getlong.
1891 Make char *prefix be const.
1892 Fix how certain range types are mapped into builtin unsigned int types.
1894 Remove 2 #includes. They cause errors (on Sony, at least),
1895 and aren't needed (they wern't in earlier versions).
1897 print_address_symbolic should never demangle labels
1898 (since it prints *assembler-level* labels).
1900 [This was superseded by the change to printcmd below.]
1903 Add some "volatile" return types to avoid warnings.
1904 If MISSING_VPRINTF add vprintf function and not just macro
1905 (since vprintf is used in printcmd.c).
1907 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
1908 (The latter isn't grokked by some PCC-based compilers.)
1910 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
1912 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
1913 * nindy-share/coffstrip.c
1914 Added some forward declarations (otherwise, gcc complains
1915 about implicit extern redefined as static).
1917 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1919 Changes inspired by Per Bothner:
1920 * printcmd.c (print_address_symbolic): Take additional parameter
1921 specifying whether to demangle.
1922 (print_address): Pass in asm_demangle to control demangling.
1923 (print_address_demangle): New fn, takes explicit arg to control
1925 * utils.c: Add new vars demangle and asm_demangle, and let them
1927 (fputs_demangled): If !demangle, just print the argument.
1928 (fprint_symbol): If !demangle, just print raw symbol.
1929 * valprint.c (val_print): Call print_address_demangle rather than
1930 print_address, to cause demangling to depend on the global
1931 rather than assembler-level demangling setting.
1932 * WHATS.NEW, gdb.texinfo: Document.
1934 * main.c (show_command): Show all settings if no arg.
1935 (initialize_main): Make "info set" the same as naked "show".
1936 * command.c (cmd_show_list): Handle prefix commands in the
1937 list, and print the name of the setting as well as its English
1938 description and value.
1940 Allow gdb functions to specify where a line should wrap if it
1941 exceeds the size of a terminal line. Use it to make the output
1943 * utils.c (set_screen_width_command): New fn, mallocs a buffer
1944 of the right size when screen width changes.
1945 (set_screensize_command, screensize_info): Remove #if 0'd fns.
1946 (wrap_here): New fn, indicates a point in the output where we
1947 should wrap the line rather than just letting it overflow at a
1949 (fputs_filtered): Implement wrapping.
1950 (n_spaces): New fn, returns a pointer to N spaces.
1951 (print_spaces_filtered): Use n_spaces.
1952 * defs.h (n_spaces): Declare.
1953 * stack.c (print_frame_info): Wrap with 4-space indent after
1954 fn name and before filename and line number.
1955 * printcmd.c (print_frame_args): Wrap with 4-space indent
1956 before each argument name is printed.
1957 * valprint.c (value_print): Wrap with no indentation before
1959 (val_print_fields): Wrap with indentation relative to nesting
1960 level before each field name.
1961 (val_print): Wrap with nesting indentation before array elements.
1962 * command.c (do_setshow_command): Avoid extra newlines,
1963 wrap with 4-space indent around values printed, end with period.
1964 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
1966 * breakpoint.c (breakpoint_1): Implement addressprint for
1967 "info breakpoints" display. Change file name and line number
1968 format to " at file:nnn" rather than " (file line nnn)".
1969 * gdb.texinfo: Document.
1972 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1974 Frozen for gdb-3.92.6 release.
1976 README, WHATS.NEW: Update for 3.92.6 release.
1978 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
1979 coffread.o from configs since it is now built by default.
1980 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
1981 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
1982 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
1983 from configs since it is now built by default.
1985 Makefile.dist: Update for release 3.92.6. Handle files that
1986 have been moved to ../include, ../getopt, or ../bfd. Add
1987 saber.suppress and tests directory. Add config.status to
1988 the release (it will say "none").
1990 coredep.c: Minor formatting fixes.
1992 These changes were made in early December but only checked in now:
1993 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
1994 nindy-share/nindy.c: lint
1995 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
1996 register values coming back from the target; we store values
1997 in target byte order everywhere.
1999 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2001 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2003 * valprint.c (cplus_val_print, val_print_fields): New functions,
2004 which print C++ objects. They conspire to avoid printing a
2005 virtual base class more than once, following all the twists and
2006 turns of C++ virtual base rules.
2007 (val_print): Call the above rather than do it by hand.
2009 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2010 symbol file, not for added files like shared libs. This really
2011 needs to be generalized to a timestamp per file.
2013 * core.c (cleanup_core): Avoid coredump if no core file.
2015 * config.gdb: Accept -host or -target in place of +host or
2018 * coffread.c (find_linenos): Avoid desupported BFD interface
2019 to line numbers. We still read them manually rather than using
2020 BFD's "generic" features.
2022 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2024 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2026 * Makefile.dist: Eliminate use of $< in explicit targets.
2028 * readline/Makefile: Use $< rather than $*.c, which does not
2029 include the VPATH in GNU Make.
2031 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2032 copies of tconfig/i960, added for global configuration
2033 compatability. All i960 versions can read both coff and b.out.
2035 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2036 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2039 * TODO: Think of more things to do.
2041 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2043 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2044 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2045 64-bit float conversion.
2047 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2048 equivalent to sun?os4 so global config works.
2050 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2052 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2054 * main.c: Only declare linesize once; declare pagesize not at
2055 all, since it is never used.
2056 (main): Clear newly allocated line before it is used.
2058 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2060 Further stabilization for the Intel 960.
2062 * Makefile.dist: Parameterize the location of the "include"
2063 and "bfd" directories, as well as "getopt". Add symfile.c.
2064 Link in both dbxread and coffread. Fix up "make depend" to
2065 rewack the locations of include, bfd, and getopt in its output.
2067 * README: Document moving include files, improve some of
2070 * coffread.c: Move common code out to symfile.c. Change
2071 symbol_file_command style interface to use new *_symfile_init
2072 and *_symfile_read interface under BFD. Use BFD internal
2073 info to locate line table, symbols, etc.
2075 * core.c (core_fetch_registers): Rename to get_core_registers
2076 to avoid confusion with fetch_core_registers.
2077 (register_addr): Move to coredep.c, which is already machine
2078 dependent. This leaves core.c pretty clean of dependencies.
2080 * coredep.c (register_addr): Accept this routine from core.c.
2082 * dbxread.c: Move common code (with coffread.c, etc) into new
2083 symfile.c. Each psymtab now contains a pointer to the
2084 format-dependent function that knows how to read it in. Make
2086 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2087 (process_one_symbol): Add code to complain about a "compiler bug
2088 we muzzle here", if we actually see it.
2090 * eval.c (evaluate_subexp): Insert missing "break" statements
2091 in code that determines whether a variable is an lvalue in
2092 memory, register, or whatever. I detected this via a compiler
2093 bug in which it *almost* mashed out the whole switch statement.
2095 * gdb-int.texinfo: Add minor sections on configuring gdb for
2096 release, and about the README file.
2098 * infcmd.c (registers_info): Fix formatting somewhat. Still
2099 not as pretty as before, but it handles byte swapping.
2101 * remote-nindy.c: If data cache routines are interrupted while
2102 waiting for the remote end, be sure that any uninitialized cache
2103 blocks are on the free list, not on the valid list!
2105 * symfile.h: Flesh out this header file with all the various
2106 routines and variables that have been merged in from dbxread.c
2107 coffread.c, and symtab.c to symfile.c.
2109 * symfile.c: New file, containing code common to dbxread.c,
2110 coffread.c, and some code from symtab.c. All generic code for
2111 reading symbol files should be in here now.
2112 (unrecord_misc_function): Remove unused function.
2114 * symtab.h: Remove file-reading things to symfile.h.
2116 * symtab.c: Remove file-reading things to symfile.c.
2118 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2119 to decode i960 fault types.
2121 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2122 target.c: Change type of the "resume" function from int to void,
2123 since its result was never used.
2125 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2127 * main.c: Replace "stupid" with "caution"; you now "set caution
2130 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2132 * infcmd.c (do_registers_info): Call val_print to deal with the
2133 byte order of the registers being printed. FIXME, this makes
2134 the formatting of the output uglier.
2136 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2137 defined, call it for signals the debugger doesn't itself use.
2138 The i960 uses this for more detailed fault information.
2140 * remote.c (remote_open): If arg is null, print help rather than
2143 * sparc-xdep.c (register_valid): Avoid declaring size, since
2144 various modules will think of various sizes depending on the
2145 architecture of their tm-file. FIXME, we need protection against
2146 actually entering one of those modules, which would clobber
2147 storage if not for the target architecture compiled into gdb.
2149 * stack.c (up_command, down_command): Always print the frame
2151 (up_silently_command, down_silently_command): New commands
2154 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2156 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2157 more parameters than it used to.
2159 * findvar.c (registers): Increase slop to 256 bytes, which should
2160 protect us against even most RISC machines with large register
2162 (locate_var_value): Move declaration inside related ifdef.
2164 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2165 throughout, to avoid throwing away buffered input from the board.
2166 (nindy_wait): Supply_register takes addr_of_value, not value.
2167 (i960_print_fault): Renamed from i80960_fault.
2168 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2169 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2171 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2172 we can set the PC in the call to proceed(). Unpush nindy_ops
2173 before pushing it on top, to avoid message to user. Eliminate
2174 commentary from Unix machines that just misleads here.
2175 (reset_command): Fix error message to suggest target command.
2177 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2179 Release 3.92.5 as frozen.
2181 Stabilize the merged release...with help from lint, Saber C,
2184 Everywhere: Add include files needed to declare return types
2185 of functions called.
2187 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2189 * breakpoint.h: Add undeclared breakpoint functions, and some
2190 functions for display handling since I couldn't think of a better
2193 * breakpoint.c (insert_breakpoints): Make code for disabling
2194 shared library bkpts more likely to work. It's used when we
2195 rerun a program and stop before the shared library has been
2197 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2198 cast from pointer, so it squeezes through catch_errors.
2199 (bpstat_stop_status): Fix logic broken some time ago. We now
2200 always create a bpstat if the stop address matches a breakpoint,
2201 even if we don't stop there -- just like the old code used to do
2202 before I got my fingers into it (sigh).
2203 (breakpoint_1): Print "ignore count" after "stop only if"
2204 condition, since that's how it actually works.
2205 (mention): Handle watchpoints as well as breakpoints.
2206 (watch_command): use set_raw_breakpoint and mention to do most
2207 of the work (and initialize all the fields!). Only pass one
2208 arg to parse_c_expression, since that's all it takes.
2210 * command.c (not_just_help_class_command): Rename arg to args
2211 since we ignore "unused argument" warnings on vars named "args".
2212 inflow.c (child_terminal_info): ditto.
2213 infptrace.c (kill_inferior): ditto
2214 main.c (catch_errors, version_info, quit_command, pwd_command,
2215 source_command, dump_me_command, editing_info,
2216 set_history_size_command, set_history, show_history,
2218 stack.c (locals_info): ditto
2219 target.c (target_files_info): ditto
2220 valprint.c (set_input_radix, set_output_radix): ditto
2222 * core.c: Remove old variables for handling core and exec file
2223 sections (data_start, data_end, stack_start, stack_end,
2224 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2225 text_end, exec_data_start, exec_data_end, text_offset,
2226 exec_data_offset, data_offset, stack_offset). They're
2227 superseded the more general build_section_table and
2229 (get_exec_file): Mention the `file' command.
2230 (read_memory_check): Rename to memory_error, and only call it
2231 in the case of an actual error.
2232 (read_memory, write_memory): call memory_error.
2233 (core_fetch_registers): Register section name is ".reg".
2235 coredep.c: Remove a bunch of crud now that all this file does
2236 is pull the registers out of a core file.
2237 (fetch_core_registers): Rewrite to actually work, I hope.
2239 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2240 Replace index() with strchr(). Remove all the pre-BFD macro
2241 definitions for accessing the symbol file.
2242 (struct dbx_symfile_info): Encapsulate the information that
2243 dbx_symfile_init needs to pass to dbx_symfile_read in this
2246 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2247 dbx_symfile_discard): Rearrange symbol file reading to divide
2248 the format-specific part from the format-independent part,
2249 leaving the format-independent part such as file name expansion
2250 and opening in symtab.c. This replaces
2251 partial_symbol_file_open and partial_symbol_file_read.
2252 Symbol_file_read, add_file, add_file_target_command,
2253 add_file_addr_command move to symtab.c. Pass an explicit
2254 "mainline" flag for when reading the main symbol table, rather
2255 than relying on the offset address to be zero or nonzero.
2257 (dbx_symfile_read): Don't allow void *'s to be printed as
2259 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2260 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2261 macro" debug version really work.
2262 (read_dbx_symtab): Remove unref'd parameter inclink.
2263 Avoid swapping N_SLINE symbols, for speed.
2264 Merge N_TEXT!N_EXT case with the other external symbol
2265 definitions' case. Add comments.
2266 (start_psymtab): Allocate the symfile name in the psymtab on
2267 the psymbol_obstack, rather than using the caller's storage.
2268 (end_psymtab): Only allocate a dependencies list if there are
2270 (psymtab_to_symtab_2): Use BFD when reopening file to read
2271 its symbols for real.
2272 (read_struct_type): Add FIXME comments where it needs work
2274 (read_huge_number): Add FIXME about overflows.
2275 (read_range_type): Add FIXME about comparing a long to 1<<32.
2277 * coffread.c: Minor changes to move things closer to the new
2278 regime with symtab.c and dbxread.c Major work is still needed
2281 * exec.c (exec_file_command): Remove old variables (see core.c
2283 (xfer_memory): If memory transfer is right at the end of a
2284 section, don't lose.
2286 * findvar.c (get_saved_register): If value is in a real
2287 register, LVAL is lval_register, not lval_memory.
2289 frame.h: Declare print_sel_frame and record_selected_frame.
2291 gdb-int.texinfo: New file, for GDB internals documentation.
2292 Very simple, unformatted doc of cleanups is there for now.
2294 gdbcore.h: Remove obsolete variables that described a.out
2295 section addresses and offsets. (See core.c above.)
2296 Declare fetch_core_registers and registers_fetched.
2298 getopt.c: Declare char *alloca(); even on SPARC.
2300 infcmd.c (run_command): Call target_kill rather than
2302 (step_command, next_command, stepi_command, nexti_command):
2303 Declare from_tty parameter even though we don't use it.
2304 (run_stack_dummy): argument BUFFER is a char array, not
2305 a pointer to REGISTER_TYPE.
2306 (finish_command): using_struct_return needed a value *,
2307 not a struct symbol *.
2309 * infptrace.c (child_xfer_memory): To avoid dependency on
2310 where sections are in memory, try PT_WRITE_D and if that fails,
2311 try PT_WRITE_I. Most Unixes don't care which you use.
2313 * infrun.c (step_resume_break_shadow): Change to array to
2314 match other breakpoint shadow storage.
2315 (clear_proceed_status): Pass address of bpstat to
2316 bpstat_clear, not the bpstat itself.
2317 (child_create_inferior): FIXME comment about if the child
2319 (start_inferior): Remove old function.
2320 (child_open): Use target_kill rather than kill_inferior.
2321 (wait_for_inferior): Ditto.
2322 (insert_step_breakpoint, remote_step_breakpoint): Use
2323 new step_resume_break_shadow.
2325 * inftarg.c (child_wait): If all child processes die,
2326 pretend that the one being waited for exited with signal 42.
2328 * main.c (command_line_input): When scanning for comments,
2329 don't coredump on unclosed quotes.
2330 (quit_command): Use target_kill rther than kill_inferior.
2331 (_initialize_main): Rename class_user from "user" to
2334 * printcmd.c (print_command_1): Initialize "fmt" if no format
2335 is specified by the user.
2336 (print_frame_args): Only add to args_printed if we are
2337 actually fetching args from the stack (avoiding undefined
2339 (_initialize_printcmd): Remove bogus \{ from string.
2341 * remote-eb.c (eb_open): Avoid coredump on no argument.
2343 * remote-nindy.c: Bring out of Intel environment into new
2344 target environment. Remove all conditional compilation on
2345 I80960. Massive hacking throughout.
2346 (nindy_xfer_inferior_memory): New routine stolen from
2348 (nindy_create_inferior): New routine pieced together, probably
2349 not quite working yet.
2350 (nindy_ops): New target_ops struct for nindy.
2352 * remote-vx.c: Use write_memory rather than target_write_memory
2353 to get error checking.
2354 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2356 (vx_create_inferior): Use target_terminal_ours...
2358 * signame.c (_initialize_signame): Always initialize, since
2359 we need the table for things other than psignal.
2361 * solib.c (solib_add): Use symbol_file_add, not add_file.
2362 (solib_address): Return boolean result rather than struct
2363 pointer which nobody else knows the type of.
2365 * sparc-tdep.c, valops.c: Use write_memory rather than
2366 target_write_memory, to get error checking.
2368 * stack.c (locals_info, catch_info, args_info,
2369 get_selected_block, frame_command, up_command): Use
2370 target_has_stack, rather than have_inferior_p or
2373 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2375 * symfile.h: New file, defining the interface between the
2376 generic and object-file-specific symbol reading code.
2378 * symtab.c: Move generic symbol-reading interface to symtab.c,
2379 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2380 table to map BFD targets to symbol-reading modules in GDB.
2381 Change index to strchr.
2382 (lookup_struct_elt_type): Use error() rather than hand-made
2383 simulations thereof.
2384 (lookup_partial_symbol): Speedup slightly when length == 0.
2385 (symbol_file_add): New function.
2386 (symbol_file_command): Call it.
2387 (symfile_open, symfile_init): New function.
2388 (add_file_target_command, add_file_addr_command): moved from
2391 * target.c (target_command): use target_kill.
2393 * target.h (target_files_info): Don't declare, never called
2396 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2397 files to determine stack end address.
2399 * valarith.c (value_x_binop, value_x_unop): Change error message
2400 to be more useful. Pass proper argument to value_struct_elt.
2402 * valops.c (value_assign): FIXME comment that long long
2403 bitfields will break here.
2405 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2406 Update `make saber_gdb' to work better.
2408 * TODO: A woman's work is never done.
2410 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2411 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2412 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2413 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2414 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2415 valops.c, valprint.c, exec.c: Lint.
2418 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2420 Continuing Intel 960 port merge of GDB.
2422 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2423 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2424 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2425 Wack over "make depend" so it handles files in subdirectories
2426 vx-share, nindy-share, bfd, and in the current directory.
2428 * blockframe.c (get_prev_frame_info): Remove fatal error
2429 if stack not defined.
2431 * core.c (core_open, core_detach): New functions that handle
2432 the old "core-file" command as "target core" and "detach" instead.
2433 (core_file_command): Call them.
2434 (core_xfer_memory): Use common routine xfer_memory.
2436 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2437 dbxread now uses bfd for everything but symbol reading itself.
2438 BFD internals are used to drag out the relevant file offsets.
2439 (partial_symbol_file_open): Change args all around for BFD.
2441 * symtab.c: Rename "value" to "val" everywhere, so we can
2443 (symbol_file_command): New command, moved from dbxread.c
2444 and coffread.c. It uses BFD to read the file, then vectors
2445 based on its type, to dbx or coff symbol readers.
2446 * symtab.h: Extern a few vars for symbol_file_command.
2448 * target.h: Breakpoint takes a char * save area, not a char **.
2450 * valprint.c (val_print): When unpacking bitfields, offset
2451 the address in gdb of the value, if it is declared with a shorter
2452 type. Remove the last "runtime kludge test" of host byte order.
2454 * utils.c: Remove old my_bfd_read routine.
2456 * stack.c (frame_info): Use target_has_stack. Print program counter
2457 register's actual name rather than "pc", since it's called the
2458 "ip" (instruction pointer) on the i960 (sigh).
2460 * target.c (target_command): Add command for selecting a target
2461 type and calling its open routine. This is used for initiating
2462 communication with a particular target, in a generic way.
2464 * tm-i960.h: Update for modern gdb. Remove semicolons from
2465 various macros. Handle reading struct return convention, and
2466 error-out attempts to return structs with the "return" command.
2467 Be sure gdb doesn't think we know how to call functions in the
2470 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2471 to i960_xxx in lower case.
2472 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2473 not being defined yet.

2476 wait_for_inferior during open.
2477 (remote_xfer_inferior_memory): Return length written rather
2480 * remote-vx.c (target_command -> vx_open): Use new generic
2482 * remote-eb.c, inftarg.c, exec.c: ditto.
2484 * infrun.c: Fix comments.
2485 (attach_program -> child_open): Use new generic target command.
2486 (wait_for_inferior): Clear saved register values before target_wait,
2487 so target_wait can set some of them if convenient.
2489 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2490 Return success indicator, not void.
2491 (child_xfer_memory): Avoid fetching initial word if we'll
2492 overwrite it anyway.
2494 * infcmd.c (attach_command): Use new generic target open routine.
2495 (_initialize_infcmd): Update doc on attach and detach commands.
2496 (do_registers_info): Merge in a byte-order problem as a FIXME
2499 * findvar.c (find_saved_register): Avoid problem in current frame.

2515 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
2517 Merge Intel 960 port of gdb, continuing...
2519 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
2520 symbol_file_command): Pass from_tty arg to hush 'em up.
2522 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
2523 Add magic numbers for 960 COFF format.
2525 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
2527 Merge Intel 960 port of gdb, from Intel "1.2" release.

2548 Fri Apr 20 13:47:15 PDT 1990
2551 Thu Apr 19 09:54:28 PDT 1990
2552 Add 'reset' command.
2554 Wed Apr 18 09:48:07 PDT 1990
2555 After opening remote tty, wait for 1 second to go by without input
2556 from it before trying to talk to NINDY (fixes problems with the
2557 Heurikon HK80/V960E).
2559 Mon Apr 4 16:33:05 PDT 1990
2560 Some output was not being suppressed in 'batch' mode.
2562 Thu Mar 22 15:31:11 PST 1990
2563 Ask user if old symbol table should be deleted when new file is
2566 Allow user to run a program downloaded before gdb960 was brought up.
2568 Correct "exec-file" help message for i80960 context.

2593 Mon Oct 2 15:56:31 PDT 1989
2595 Added 960CA disassembly support.
2597 To simplify maintenance:
2598 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
2600 - eliminated opcode.h: incorporates tables into i960-pinsn.c
2601 - moved 960-specific routines from i960-pinsn.c to i960-md.c
2602 - made disassembly interface identical to that in gdmp960.
2606 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
2608 * target.h: Allow targets to stack. Add target_has_memory,
2609 _registers, etc. Restructure memory access and "info files"
2610 to walk the target stack.
2611 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
2612 target.c: Change tables to match target.h.
2613 * inflow.c (child_mourn_inferior): pop child_ops.
2614 (generic_mourn_inferior): Use new has_stack flag.
2615 * infptrace.c (child_xfer_memory): New memory regime.
2616 * inftarg.c (child_files_info): New "info files" regime.
2617 * remote-eb.c: New memory regime, new info files.
2618 * remote-vx.c: New memory regime, new info files. Now use
2619 separate targets for VxWorks attachment to machine, and
2620 actually running a process under VxWorks, since one has
2621 stack & execution & regs and the other doesn't.
2622 * remote.c: New memory regime, new info files.
2623 * sparc-xdep.c (fetch_core-registers): New memory regime.
2624 * target.c: New routines and support for stacked targets,
2625 new memory regime, new info files regime.
2628 Generalize section handling for an arbitrary number of sections,
2629 including use of the new BFD (binary file) library.
2630 * gdbcore.h: Add struct section_table.
2631 * exec.c (build_section_table): Iterate all sections and
2632 record what gdb needs to know about them.
2633 (exec_command): Use it.
2634 (exec_xfer_memory): Use the table.
2635 (exec_files_info): Print the table.
2636 * core.c (core_file_command, core_xfer_memory, core_files_info):
2638 * source.c (find_source_lines): Use bfd_get_mtime.
2639 * dbxread.c: Quick changes to make it compile with new BFD.
2640 * utils.c (error): Avoid using bfd_error in generic routines.
2642 * core.c (core_fetch_registers): Get from the ".regs" section of
2644 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
2646 * inferior.h (attach_flag): Export.
2647 * infcmd.c (run_command): use new target_create_inferior.
2648 * infrun.c (child_create_inferior): Don't return result.
2649 * Makefile.dist (VERSION): 3.91.4.
2651 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
2653 * breakpoint.c (bpstat_num): Handle breakpoints which have
2654 since been deleted, such as temporary breakpoints.
2655 infcmd.c (program_info): ditto.
2657 * core.c (core_file_command): Display the frame where the core
2662 * remote-vx.c (target_command): Merge in target command from
2663 targ-vx.c. A few other cleanups.
2665 * TODO, Projects: Lots more stuff to do...
2667 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
2669 Massive changes to wall off the remote-debugging interface
2670 behind a function vector. The port to handle VxWorks targets
2671 is also part of this.
2673 All files: Replace references to renamed functions,
2674 remove references to remote_debugging, remove references to
2675 have_include_file, have_core_file in favor of target_has_stack,
2676 target_has_memory, etc.
2678 * Modularize the breakpoint interface.
2679 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
2680 a breakpoint instruction.
2681 breakpoint.c: struct breakpoint's shadow_contents now sized as
2683 (insert_breakpoints): Vector to target to install breakpoints.
2684 (remove_breakpoints): Vector to target here too.
2685 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
2686 sparc-tdep.c (single_step): Use new breakpoint interface for
2687 the single-step breakpoints.
2688 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
2689 New file, contains routines to insert and remove breakpoints by
2690 reading out the old contents and later replacing them. This is
2691 how ptrace breakpoints work, and many remote systems as well.
2693 * tm-vxworks68.h: New config file, overrides a few things for
2694 Wind River's preferences.
2696 * target.h: New file, for transfer vector used to talk to the
2697 inferior (child, attached, core, exec, remote, etc). All accesses
2698 to the thing being debugged should come through these vectors.
2699 target.c: New file, routines to handle transfer vector.
2700 (various files): Add transfer vectors XXX_ops for the various
2701 targets and pseudo-targets (core files, etc) we support.
2703 * breakpoint.c (bpstat_stop_status): Further explorations of
2704 watchpoints and why things don't work all the time.
2705 (bpstat_alloc): New fn to allocate a bpstat and chain it.
2707 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
2708 the local gdbinit if it doesn't already have it.
2710 * core.c (core_ops): add and install.
2711 Allow core debugging without exec file.
2713 * dbxread.c (free_and_init_header_files): Merge two fns.
2714 (end_symtab): Free named symbol table when a new version comes in.
2715 (read_dbx_symtab): Relocate all kinds of symbols with base
2716 address. First step toward handling different text, data, bss
2718 (add_file_addr_command): Renamed add_file_command.
2719 (add_file_command): Vector to remote handler.
2720 Add "load" as an alias for "add-file" command.
2722 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
2723 non-returning functions.
2725 * exec.c: Add exec_ops, and push it as a target when an exec
2728 * infcmd.c (run_command): Pass executable file name and arg list
2729 separately when starting an inferior. Permit "run" when no exec
2730 file is specified, for VxWorks.
2731 (detach_command): Move to child_detach in inftarg.c.
2733 * inftarg.c: New file. Unix-child-specific routines, and the
2734 child_ops structure.
2736 * inferior.h (registers): Export "registers" as the way for
2737 target dependent register handlers to find gdb's local copy of
2738 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
2739 since it is now used by places that want wait_for_inferior to
2740 handle the grunge but want to see every trap from the inferior.
2742 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
2743 Eliminate remote_debugging hooks in terminal handling.
2745 * infrun.c: Replace start_inferior with child_create_inferior.
2746 Move all the hair of Unix shells and ptrace idiosyncracies into
2747 child_create_inferior, so remote handlers don't have to deal.
2748 Remove running_in_shell. Rename stop_after_attach to
2749 stop_soon_quietly, and use it in a few other places where we want
2750 to just call wait_for_inferior and get control back on the first
2751 trap. trap_expected now never takes a value > 1.
2752 (init_wait_for_inferior): Initialize static vars when a new
2755 main.c (gdbinit): Add new hook for .gdbinit file name, let
2756 it be overridden by config files as GDBINIT_FILENAME.
2757 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
2758 Both of these are used for VxWorks gdb.
2760 mcheck.c: rename include file "gmalloc.c" to avoid problems
2761 with system include file "malloc.c".
2763 param-no-tm.h: New include file, same as param.h but does not
2764 include the default "tm.h" file. This is used in files where
2765 the target is known, e.g. remote-eb.c or sparc-xdep.c.
2767 param.h: Now just a shell that includes tm.h and param-no-tm.h.
2769 remote-vx.c: New file, VxWorks remote debugging support. Uses
2770 RPC routines that are shared with the target system, in directory
2773 remote.c: Vectorize remote interface.
2775 source.c: Globalize source_path, and make an alias "l" for "list"
2776 since we now have the "load" command.
2778 sparc-xdep.c: Use new param-no-tm.h.
2780 symmisc.c (free_named_symtab): Add new function from Wind River.
2781 However, ifdef it out for now while we think about what it should
2784 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
2786 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
2787 non-Unix-children handle this with their own code in the target
2790 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
2791 source and target lists. Add vx-share to default list of include
2792 directories. Add new files to src and target lists: mem-break,
2793 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
2794 ${srcdir} versions of munch and createtags are used.
2796 * valops.c (find_function_addr): Split out of call_function.
2797 (call_function_by_hand): Rename call_function; this function
2798 calls functions in the target by laboriously patching the target
2799 word-by-word with the right stack, args, regs, etc.
2802 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
2804 Handle AMD 29000 a bit better.
2806 * remote-eb.c (readchar): Mask received char log to make it readable.
2807 (remote_start): Pass arguments down to executing program.
2808 Make startaddr unsigned.
2809 infrun.c (start_inferior): Accept args, pass them to
2811 infcmd.c (run_command): Pass args down to start_inferior.
2813 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
2814 the target object file format.
2815 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
2817 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
2818 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
2820 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
2822 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
2823 * TODO: We did a few things, we have more to do though.
2825 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.

2831 (sparc_frame_find_saved_regs): Simplify and fix what we find.
2832 (sparc_push_dummy_frame): Simplify and fix what we push.
2833 (sparc_pop_frame): Slightly more hair here, deciding whether
2834 we are restoring a saved PC or returning to a return address in %i7.
2835 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
2837 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
2838 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
2839 * obstack.h (chunkfun): ditto.
2840 * defs.h (xmalloc, xrealloc): ditto
2842 * utils.c (quit): Grab the terminal from the child if necessary.
2844 * inflow.c (term_status_command): Rename to term_info, change
2847 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
2848 (is_delayed_branch): Speed up.
2849 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
2850 Still missing some float ops, and needs testing.
2852 * Support for input and output radixes other than base 10
2853 * defs.h (input_radix, output_radix): Declare.
2854 * expread.y (yyparse, parse_number): Handle changes of input
2855 radix, and ambiguous names-or-numbers in radixes >10.
2856 * printcmd.c (print_scalar_formatted): Print formatted hex
2857 numbers in varying column widths.
2858 * valprint.c (val_print): Use output_format to print scalar ints.
2859 (set_input_radix, set_output_radix, set_radix): Create.
2860 (set_output_radix): Set output_format from output_radix.
2861 (_initialize_valprint): add `set radix' but leave the others off.
2863 * main.c (execute_command): Let stupid questions be turned off.
2864 (_initialize_main): Handle "set stupidity", etc.
2866 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
2867 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
2869 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
2871 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
2872 bfd stuff is still screwed up, but with some manual work, it
2875 * breakpoint.c (bpstat_do_actions): Start over if a command
2876 proceeds the inferior, since the inferior will have stopped and
2877 will need to have its new stop-actions taken care of.
2879 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
2880 compiler fits, simplify it.
2882 * gdb.texinfo (directory command): Doc new dir command.
2883 source.c (directory_command): "dir" now puts things on the front
2884 of the path, moves dups up front, and handles multiple names
2885 on the command line, inserting each one in order. It also
2886 blows away cached line and full_filename info.
2888 * stack.c (backtrace_command): Skip "more stack frames follow"
2891 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
2892 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
2893 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
2894 The only odd one was Gould NP1, which had defined vprintf to
2897 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
2898 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
2899 variable, inspect_it.
2900 valprint.c (print_string, val_print): Use the global inspect_it
2901 to indicate whether to print in Epoch style or normal style.
2903 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
2905 * printcmd.c (call_command): add an alias for the "print" command
2906 which runs expressions and doesn't print the result if void.
2907 (print_command_1): implement it.
2909 * command.c: Remove #if 0'd code. Initialize all the fields
2910 in add_cmd (). Rename do_nothing_command to
2911 not_just_help_class_command, and make it externally visible.
2912 command.h: add user_commands to struct.
2913 * main.c (define_command): Don't overload c->function with a char
2914 string as well as a function pointer.
2916 * eval.c (evaluate_subexp): Reinstall tiemann changes to
2917 calling convention of value_struct_elt () that got dropped in
2920 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
2921 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
2923 * tm-sparc.h (POP_FRAME): replace some constants with defines.
2925 * sparc-xdep.c (store_inferior_registers): defer stores to regs
2926 until a good time (e.g. when we are about to run the child),
2927 saving ptrace calls.
2928 * infrun.c (proceed): handle DO_DEFERRED_STORES.
2929 * tm-sparc.h: define DO_DEFERRED_STORES.
2931 * sparc-xdep.c (store_inferior_registers): when storing float
2932 registers, don't store stack regs too. When storing the SP,
2933 however, DO store the stack regs too. This fixes a bug in which
2934 the dummy frame is not recognized when a call_function finishes,
2935 because its frame pointer (in the stack regs) was never
2937 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
2938 even though we don't know how to read them from an inferior.
2939 valops.c (call_function): Comment about storing SP.
2941 * infrun.c (save_inferior_status): Save away the original bpstat
2942 chain so it can be restored later. Install the copied version for
2943 use by whoever saved the status. It will be blow away by
2944 restore_inferior_status, and the original chain restored. This is
2945 important for people who have pointers into the original.
2947 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
2948 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
2949 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
2952 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
2954 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
2955 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
2956 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
2958 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
2960 * Merge Mike Tiemann's multiple inheritance changes from Sun.
2961 Store the baseclasses in a type struct starting from array element
2962 0 rather than from the unusual array element 1.
2964 dbxread.c: the above.
2965 (virtual_context): Add
2966 Read new debug information about which virtual function table
2967 a virtual function is from, and store it in fn_field.fcontext.
2969 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
2970 TYPE_FN_FIELD_STATIC_P.
2972 symtab.c: the above.
2973 valops.c: the above. Handle pointer casts of object *'s.
2974 (search_struct_method): Add.
2975 (value_struct_elt): First arg is now a pointer to a value, and is
2978 valprint.c: the above.
2979 values.c (value_virtual_fn_field): Add type arg. Handle
2980 offsetting to the proper object when calling virtual fns.
2982 (baseclass_addr): Add valuep arg.
2984 * README: Document the current state of BFD config (missing).
2985 * TODO, ChangeLog, Makefile.dist: Roll version.
2986 * WHATS.NEW: Add summary of changes since 3.5.
2988 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
2990 * dbxread.c (read_struct_type): Clear bit vectors whenever
2992 symtab.c (B_CLRALL): define.
2994 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
2995 using == rather than =. Huh... This fixes the dreaded problem
2996 wherein builtin_type_int becomes TYPE_CODE_FLT.
2998 * core.c (info_files): Show the inferior pid.
3000 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3001 already knows how to look in the source directory.
3003 * Remove psymtab hair from many places. Remove duplicated code
3004 for searching symbol tables. Hide psymtabs from most places.
3005 Make it fast to get from a psymtab to its symtab.
3007 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3008 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3009 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3010 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3011 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3012 new symtab completely. New psymtabs get symtab pointer
3013 initialized to zero. Remove MI warning printf.
3014 symtab.h: Comments. Add psymtab to symtab pointer.
3015 (PSYMTAB_TO_SYMTAB): New macro.
3016 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3017 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3019 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3021 (print_frame_info): Avoid special-casing symbols that have not yet
3024 * source.c (open_source_file): Quick path if we have already
3025 located the source file by its full name.
3027 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3028 find_pc_psymtab. When a name is found in the misc function
3029 vector, search the symbol table for its mangled name, not the
3030 name that the user typed.
3032 * bfd.h: Fix missing comment terminators, make #endifs match.
3034 * valarith.c (value_less): Handle unsigned int comparisons.
3035 Add FIXME about pointer compares, which assume host and target
3036 pointers are the same.
3038 * command.c (do_nothing_command): lint
3039 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3040 fix comments on debug symbol format for visibility. Actually set
3041 visibility of symbols.
3042 main.c (echo_command): lint; use <readline/history.h>.
3043 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3044 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3045 pointing past end of allocated memory; saber complains.
3046 obstack.h: Declare the external functions that we use.
3047 valarith.h: use <string.h>
3048 solib.c (solib_add): lint.
3050 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3052 * main.c (initialize_main): Default info_verbose to off, now that
3053 symbol reading is fast.
3054 (quit_command): Avoid clobbering exec_bfd while quitting.
3056 * Initial BFD (binary file diddling library) merger:
3057 coffread.c: Change AOUTHDR to struct exe_hdr.
3059 core.c: initialize initialized data at compile time.
3060 (core_file_command): Move from coredep.c, convert to bfd.
3061 (xfer_core_file): Convert to bfd.
3062 exec.c (exec_file_command): use bfd routines.
3064 mips-tdep.c: Remove exec_file_command and friends.
3067 * coredep.c: (fetch_core_registers) Convert core_file_command to
3068 fetch_core_registers.
3069 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3071 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3072 (my_bfd_read): More bogosity, which I don't think we call.
3073 (program_name): Remove this atrocity asap!
3075 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3078 values.c: allocate_repeat_value was not clearing the
3079 optimized_out field.
3080 (value_static_field): minor stylistic fix (wrong macro was used).
3081 valops.c (value_struct_elt_for_address): didn't work for C++
3084 * signame.c (_initialize_signame): Initialize signal names once.
3086 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3087 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3088 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3090 * remote-eb.c: Support user-settable baud rates on the serial port.
3092 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3094 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3096 * tconfig/sun3os4: Remove warning about native assembler,
3097 since it also occurs in the xconfig file.
3099 * findvar.c (registers): Allocate some slop after `registers'
3100 to prevent stray accesses from trashing the next variable.
3102 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3103 on the sun-3, by changing the #ifdef from `sun3' (which is not
3104 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3105 vars, which happened to follow `registers' in the executable.
3107 * readline/history.c (history_search): Heed gcc-2's advice
3108 and parenthesize && inside ||).
3110 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3111 tm-29k.c: Insert FSF copyright headers.
3113 * remote-eb.c: Better comments.
3115 * Makefile.dist: Update to 3.91.6.
3116 * TODO: note PREPARE_TO_STORE problem.
3118 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3120 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3122 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3124 * infrun.c (wait_for_inferior, at end): Don't set up
3125 prev_* if the inferior no longer exists.
3127 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3128 CANNOT_EXECUTE_STACK.
3129 valops.c (call_function): Use it.
3131 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3133 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3134 infrun.c (wait_for_inferior, 2 places): Use it.
3136 * values.c (value_being_returned): Only use
3137 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3139 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3140 right thing for remote-eb.c.
3142 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3143 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3145 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3146 (FRAME_FIND_SAVED_REGS).
3148 * findvar.c ({fetch,store}_registers): Check for
3149 REMOTE_{FETCH_STORE}_REGISTER macro.
3151 * findvar.c (get_saved_register): Add argument lval and
3152 change meaning of argument addr.
3153 findvar.c: Change calls to get_saved_register to reflect
3154 new calling convention.
3155 valops.c (value_assign): Use get_saved_register instead of
3156 find_saved_register.
3158 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3160 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3161 an (uninitialized) pointer to one. Use "&" when passing it
3164 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3166 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3169 * coffread.c (symbol_file_command): Put semicolon after
3171 Put safe_to_init_tdesc_context in #if defined (TDESC).
3172 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3173 coffread.c: #include <sys/stat.h>.
3174 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3175 Add missing ')' in check for "lc%" and friends. Remove
3177 Declare read_one_sym() at top of file.
3178 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3179 MC68WRMAGIC can have the same value without causing a duplicate
3182 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3184 * Allow a Makefile to be built without building the
3185 tm and xm file links that screw up builds in subdirectories.
3186 This is done with `config.gdb none', then you can do things
3187 like `make gdb.tar.Z'.
3188 * tconfig/none: Config file for no target system
3189 * xconfig/none: Config file for no host system
3190 * config.gdb: If no TM or XM files are called out by the
3191 host or target file, don't make links for them.
3193 * cplus-dem.c: Add documentation.
3195 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3196 simple error, so the user's gdb doesn't crash due to some object
3197 file problem (e.g. somebody is rebuilding the file out from under
3200 * printcmd.c (print_address_symbolic): demangle the symbol.
3202 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3203 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3204 (alldeps.mak): sort and uniq all results from this; duplicates
3205 hose gdb.tar.Z link building. Remove RCS files from
3206 tconfig and xconfig. Add config files for sun386. Add
3207 a few odd files to OTHERS and HFILES.
3209 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3211 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3212 Roll version number to 3.91.5. Make lint work in bindir.
3214 * README: Document cross-debugging and new file structure.
3216 * blockframe.c: Lint. Include "value.h" to declare read_register.
3217 (find_pc_partial_function): remove duplicate line.
3219 * command.h: Lint. Declare error_no_arg and dont_repeat.
3221 * tm-news.h: Remove inadvertently duplicated stuff.
3223 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3224 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3226 * config.gdb: Allow `config.gdb host target' form. Clean
3227 up previous change that printed bogus messages when you just said
3230 * core.c: #include "command.h" for lint.
3233 * main.c: Remove some casts of enums. Lint.
3240 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3242 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3243 read it from memory. This will allow us to save ptrace calls
3244 eventually. Changed caller single_step too.
3246 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3247 that we aren't going to use, saving many ptrace calls, especially
3248 when watchpointing or single stepping. Use some #define's for
3250 (store_inferior_registers): Ditto.
3251 (core_file_command): Use some #define's for constants.
3253 * tm-sparc.h: Add #define's for some register numbers, so we
3254 can eliminate the use of random constants in sparc-xdep.c.
3256 * stack.c (frame_command, print_frame_info, up_command,
3257 down_command) Remove frame_changed, since it
3258 causes a bug and doesn't seem to do anything useful. In some
3259 places it was used as a flag, in others as a stack level (?).
3261 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3262 default is to use the portable (vprintf) version rather than the
3264 * xm-news.h (MISSING_VPRINTF): Add.
3266 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3268 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3270 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3271 about linking debugged programs -Bstatic in the sun?os4 config
3272 files in tconfig and xconfig subdirectories.
3274 * main.c (main): Remove unreached exit(0) now that we exit
3277 * Create TODO file for online bug list. There are too many
3278 "little" bugs to keep track of on paper.
3280 * Change Projects file to refer to bug-gdb@cygnus.com
3281 rather than kingdon@ai.
3283 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3285 * Makefile.dist (VERSION): 3.91.4 now.
3287 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3288 (condense_misc_bunches): Add sanity check that misc_count is
3289 the same as the number of symbols in the bunch.
3291 * coffread.c: rename init_misc_bunches. Pass an argument
3292 to condense_misc_bunches (a zero).
3294 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3295 every time we are called; don't rely on our caller to do it.
3296 (add_file): Remove call to init_misc_bunches.
3298 * mipsread.c: Only warn, don't error, if unknown symbol types.
3299 This keeps an old gdb from falling on its face if it sees newly
3300 extended symbol info. Rename init_misc_bunches.
3302 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3304 * Merge in changes from Per Bothner for DECstations and other
3305 MIPS stuff. The rest is Bothner speaking:
3307 The next message is a merger of Alessando Forin's mips port with
3308 mine. I've tried to use my good if biased judgment to get
3309 the best of both. It *does* need testing.
3311 Some of the changes are general, *not* mips-specific.
3314 Didn't believe in little-endian bit order.
3315 There are still inconsistencies about whether flags
3316 like BITS_BIG_ENDIAN are integer (#if ...) or
3317 boolean (#ifdef ...). I tried to paper over them.
3319 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3320 Moved some misc_function code that was common to
3321 {dbx,coff,mips}read.c to symtab.c.
3322 In the process, I think I cleaned things up a bit.
3323 At the same time, moved obsavestring and obconcat to symtab.c.
3326 Removed obsolete condense_addl_misc_bunches (use
3327 condense_misc_bunches(1) instead).
3330 Needed to include <sys/dir>, at least on DECstations.
3332 valops.c, mips-tdep.c, tm-mips.h:
3333 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3334 conventions (when STACK_ALIGN is insufficient).
3335 Needed on mips, where doubles need 8-byte alignment,
3336 but ints only need 4.
3339 Removed cruft that was not being used.
3340 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3343 Print $ before register-names (I think that makes things a little
3345 Never print two instructions, even if one delays.
3346 Removed hex-disassemble set_cmd. (This is not mips-specific,
3347 so I think the argument is whether it is generally worthwhile or not.
3348 I'm inclined to think not, given how easy it is to
3349 convert between radixes in gdb.)
3352 This is basically Alessando's code.
3353 It doesn't use obstacks; I changed it to use obstacks
3354 in a few minor places where using malloc causes a
3355 memory leak. (Probably, more places could/should be changed.)
3356 I added record_misc_function where it was missing.
3357 In symbol_file_command and add_file_command, I tried
3358 to make the code consistent with more recent versions.
3359 Minor sylistic changes in parse_procedure.
3360 Make a .gdbinfo. psuedo-symbol point back to the real
3361 procedure symbol (using the isym field).
3364 This is basically from my port, but with a lot of details
3365 and a number of routines merged in from Alessando's version.
3366 I basically used my code "raw" backtrace (use heuristics
3367 from the actual code, rather than symbol table info) - though
3368 the idea is Alessandro's. I feel my code is a little cleaner
3369 here, particularly in being a little more flexible, such as being
3370 able to handle gcc-produced code (which it now can).
3371 It also doesn't do frame caching (which is not useful
3372 more recent gdb versions).
3373 I also used my code for push_/pop_dummy, more or less.
3374 I tried to incorporate AF's code for testing sigtramp
3375 while backtracing; I probably got it wrong.
3376 Added mips_print_register, which tries to scrunch as much
3377 information as possible on a screen...
3378 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3379 under mips-pinsn.c), I don't see anything mips-specific here,
3380 and I don't see it being all that useful anyway.
3383 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3384 Use more register names (rather than hard-cases numbers).
3386 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3388 * Hack up 3.90.11 changes:
3390 * Makefile.dist (depend): parameterize $(GCC).
3391 Add solib.c and solib.o.
3392 (readline): Fix vpath for both absolute or relative SRCDIR.
3394 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3395 Also, let the part I didn't understand at least compile so
3396 I can test the rest. FIXME.
3398 * dbxread.c: Fix thinko using strcmp.
3399 (init_psymbol_list): declare static.
3400 (partial_symbol_file_open): Comment cleanups better, avoid
3401 cleaning up the string table since the caller will do that.
3402 Move the stat for mod time into symbol_file_command, temporarily.
3403 (There should be a mod time for each symbol file, eventually,
3404 to control its rereading. FIXME.)
3406 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3407 SunOS, which gives error for shared libs otherwise. (From
3408 Schaefer, probably FIXME needs work for portability.)
3410 * solib.c: Move #include "param.h" to work.
3411 Lowercase all the Uppercase Letters In the Messages.
3412 (find_solib): Clean up inferior_so_name for debug printouts.
3413 Allow no argument, to mean all shared libraries.
3415 * symmisc.c: include param.h to get CLEAR_SOLIB.
3417 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3419 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9

3460 (record_misc_function): Give correct type for N_DATA symbols.
3461 (condense_misc_bunches): do "misc_function_count = j" regardless
3463 Take code which is shared between symbol_file_command and
3464 add_file_command and put it into partial_symbol_file_{open,read}.
3465 Split add_file_command into add_file_command and add_file.
3466 Make psymtab_to_symtab read in the string table if the file
3468 Two new parameters to read_dbx_symtab and start_psymtab.
3469 tm-sunos.h: New file.
3471 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

3488 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3490 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3492 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3494 * tm-news.h: Add CALL_DUMMY_*.
3496 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.

3507 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3509 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
3511 config.gdb: If srcdir != ., create readline directory and
3512 copy a makefile into it.
3514 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
3515 consistency with POSIX.
3517 * breakpoint.c (bpstat_stop_status): Disable watchpoint
3518 when we exit its exp_valid_block.
3520 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
3522 * Makefile.dist: Bump version to 3.91.3.
3524 * Clean up handling of breakpoint commands (somewhat).
3525 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3527 inferior.h: Add breakpoint_proceeded to inferior status struct
3528 and globals; save it and restore it.
3529 (clear_breakpoint_commands): Cleanup, remove old #define.
3531 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3532 (save_inferior_status, restore_inferior_status): handle it also.
3533 (proceed): Remove earlier code that set breakpoint_proceeded.
3534 It is now set only in clear_proceed_status.
3535 (clear_proceed_status): Cleanup, use bpstat_clear rather
3536 than clear_breakpoint_commands. No callers need the stop_bpstat
3537 between clear_proceed_status and proceed.
3539 infcmd.c: Add breakpoint_proceeded definition and comment.
3540 (cont_command, jump_command, signal_command): Move call to
3541 clear_proceed_status right next to call to proceed.
3543 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3544 caller's argument while running down the chain of breakpoints.
3545 Use new variable "breakpoint_proceeded" to determine when
3546 a command that it executes moves the inferior past the
3548 (bpstat_clear): Handle NULL argument.
3549 (bpstat_clear_actions): Avoid useless call to
3550 breakpoint_auto_delete.
3551 (delete_breakpoint): Clean up bpstat's that are pointing to
3552 the deleted breakpoint from the stop_bpstat chain.
3553 (breakpoint_auto_delete): Simplify.
3555 * Clean up handling of EOF, error on stdin, etc. This was
3556 prompted by a network problem that caused gdb to go into an
3557 infinite loop filling up its malloc'd memory.
3559 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
3560 not clear_breakpoints_commands, which is now gone.
3561 (main): If command_loop returns (e.g. from EOF on stdin), do
3562 a quit_command (looping back to command_loop if quit_command
3563 doesn't really quit).
3564 (command_loop): check result from command_line_input and
3565 exit if it returns NULL, rather than passing the NULL to
3567 (gdb_readline): Free malloc'd result space before returning
3570 * utils.c (query): Handle C-d to mean "yes", just as if the
3571 input was not a terminal. Also avoid infinite loop if EOF
3572 occurs in mid-input-line before newline. This allows
3573 query to be used at EOF on stdin with reasonable results.
3575 * infrun.c (proceed): Set breakpoint_proceeded.
3577 * values.c (value_as_long): Avoid infinite recursion for enums.
3578 (_initialize_values): Fix typo in help msg (kingdon).
3580 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
3581 RL_LIB for linking. This allows -lreadline for linking
3582 and nothing for dependencies, once readline is a real library.
3584 * config.gdb: Jim Kingdon: give useful error message if the
3585 host or target type is not recognized.
3587 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
3588 it just defines it. Dumb, but deal with it.
3590 * Jim Kingdon suggests:
3591 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
3593 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
3595 * Makefile.dist (VERSION): Bump version # to 3.91.2.
3597 * Clean up Bothner's changes.
3599 * blockframe.c (clear_pc_function_cache): New function.
3600 * blockframe.c: remake cache_pc_function_* static.
3601 * dbxread.c (symbol_file_command): remove references to
3602 cache_pc_function_* variables.
3603 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
3604 * printcmd.c: Avoid kludging a global variable (addressprint)
3605 to avoid printing the address of a string twice. Instead,
3606 pass the format letter 's' down low enough that it can be seen
3607 to avoid this problem.
3608 (print_formatted): Pass format arg to value_print.
3609 (restore_addressprint): Remove function.
3610 (do_examine): Avoid hacking addressprint, cleanups and such.
3611 (print_frame_args): Add a comment to a Bothner change.
3612 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
3613 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
3614 to wipe out the values cached in blockframe.c.
3615 * symtab.c (find_method): Add comment saying how big you must
3616 allocate to be "big enough". Per being terse again.
3617 * valprint.c (val_print): Handle format letter "s" to print
3618 strings without addresses. Add comment to vtbl printing code
3619 which casts with wild abandon. Rearrange reference-printing
3621 @0xaddr: value (print w/addressprint)
3622 value (print w/~addressprint)
3623 @0xaddr (parameter lists w/addressprint)
3624 or nothing (parameter lists w/o addressprint)
3626 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
3628 * Merge more changes from Per Bothner:
3630 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
3631 annoying) that I tried to improve it. Here are my suggestions.
3633 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
3636 Do automatic de-reference when taking the address of a reference.
3638 Don't deref_ref when printing parameter lists.
3640 More attempts at treating refernences properly.
3642 In val_print, if deref_ref==0, don't print dangling " = ".
3644 Add COERCE_REF macro, which de-references an REF.
3646 * Merge changes from Per Bothner:
3648 * Fixed (Sony news)-specific configuration problems.
3649 * Fixed other problems with using vanilla pcc and libc (enum problems;
3650 assumption that vsprintf exists).
3651 * Some major speed-ups (finc_pc_partial_function now caches a match;
3652 parsing avoids duplicate symbol_lookup calls).
3653 * Changed handling of baseclasses (no longer use baseclasses field
3654 of struct type, use the first n_baseclasses fields instead).
3655 * Various minor changes/fixes, most C++-related.
3658 Cache the most previous match from find_pc_partial_function.
3659 (Save both low and high ends of matching function's pc range.)
3660 This speeds up the loop of infrun.c:wait_for_inferior quite
3661 a bit, and makes step/next commands much zippier.
3663 Added an enum->int cast (otherwise, some compilers barf).
3665 No longer set baseclass offset to 0, since multiple
3666 inheritance now mostly works.
3667 Added a number of casts, to shut up compiler warnings
3668 (after stabs where made enums, not ints).
3669 When discarding a symbol table (in symbol_file_command),
3670 must clear the cache introduced in blockframe.c.
3671 Don't convert $vtbl_ptr_type to vtbl any more.
3672 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
3673 Mask off sign bit emitted by g++ for virtual table offset.
3674 Set voffset to -1 (not 1) for static member functions.
3676 Changed parsing/lexing of names to avoid doing symbol lookup twice
3677 (once when lexing to determine symbol class, once for real).
3678 Now only call symbol_lookup once. Fields of 'this' win especially big.
3680 Subpress printing addr twice in the case of 'x/s addr'.
3682 lookup_basetype_type is no longer used.
3683 Add find_methods as recursive helper function to decode_line_1.
3684 This allows multiple inheritance to work.
3685 Also, once one or more matches has been found, do not look in
3686 base-classes. (Baseclass methods would be overridden, anyway.)
3688 Removed baseclasses array in struct type.
3689 Instead of using baseclasses[i], use fields[i-1].
3690 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
3691 Changed sign convention of voffset (previous was inconsistent).
3693 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
3695 Used to assume existence of vsprintf. Re-written to not need it
3696 if HAVE_VPRINTF is undefined.
3698 typecmp was too pessimistic. Made it less so.
3700 Don't print space after address.
3701 If vtable points to a misc symbol (with 0 offset), print it,
3702 since that indicates the actual class of the object.
3703 Changed ype_print_derivation_info to use new inheritance
3704 scheme (without baseclasses vector).
3706 In value_primitive_field, fixed some bugs left over from previous set of fixes.
3707 Also, changes needed because TYPE_BASECLASSES were removed.
3709 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
3711 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
3714 If there is no path set, and the symbols don't indicate what directory
3715 a file was compiled in, look in the current directory. But either
3716 a path or a known compilation directory will prevent this.
3719 Three independent bug fixes:
3720 * Remove the #if 0 block that breaks some stuff.
3721 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
3722 adapt gdb to either SunOS 4.0.* or 4.1.
3723 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
3726 Instantiate the class T when looking for methods in it. (Tiemann@sun)
3729 (type_print) Demangle the name being printed.
3730 (type_print_base) Handle botched demangling without coredump (tiemann).
3733 (check_stub_method): Document routine.
3734 (tiemann) fix bug for no-arg functions
3735 Avoid clobbering beyond end of malloc'd storage.
3736 Terminate the argument list properly.
3738 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
3740 * Changes merged by John Gilmore:
3743 In breakpoint_1, use new print_address_symbolic instead
3744 of find_pc_partial_function. (This forces use of assembler-level
3745 addresses, and avoids misleading non-mangled source-level names.)
3747 Generalize ansi argument such that -1 means skip arglist totally.
3748 Removed global variable print_ansi_qualifiers (which made
3749 code non-reentrant), in favor of extra explicit arguments
3750 to internal routines.
3752 Add new helper function print_address_symbolic.
3753 Use find_pc_misc_function instead of find_pc_partial_function
3754 (since we want assembler-level symbols here).
3756 Print unknown function as just "f (...)", not "f (...) (...)".
3757 Use new fputs_demangled explicitly.
3759 Fixed a typing violation (problem: value.h cannot be imported
3760 without renaming many variable in this file).
3761 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
3762 decode_line_1: Moved forward some never-reached code.
3763 Made decode_line_2 skip function prologues correctly.
3765 fputs_filtered should not demangle by default.
3766 Add new fputs_demangled to demangle on demand..
3768 Change value_struct_elt to use value_primitive_field (using recursive
3769 utility function search_struct_field). This allows foo.bar to work
3770 for multiple inheritance (so far only for data fields).
3771 Change check_field in the same way (recursive helper function
3772 to support multiple inheritance).
3773 (Note: there are more of these problems that I haven't fixed.
3774 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
3775 value_of_this: 'this' symbol name is now just "this", note "$this".
3777 Don't print static members.
3778 Avoid printing "members of <type>" if there are none.
3779 Simplified type_print_derivation_info by merging duplicate code.
3780 Remove useless blank lines in type_print_base (ptype command).
3782 Added declaration of new routine value_primitive_field.
3784 Added value_primitive_field which is generalized version of
3785 value_field that can handle multiple inheritance (non-zero offsets etc).
3786 Re-implemented value_field to call value_primitive_field.
3788 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
3790 * infcmd.c -- insert else to avoid 'delete env' coredump when you
3791 delete the whole environment. Karl Berry reported the bug.
3792 * source.c - fix openp to avoid //'s in filenames, which
3793 trigger an Emacs bug causing it to not be able to find files
3794 when running gdb in a window.
3795 * dbxread.c - zap the #if 0 that botches the add-file code.
3796 It seems to work a lot better without all the code commented out.
3798 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
3800 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
3803 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
3805 * Makefile - added a ${CFLAGS} to a couple of entries,
3806 added remote-sa.sparc.c
3807 * added remote.sa-sparc.c, a modification of remote.c
3808 which conducts a dialog directly with the SparcStation prom.
3809 * breakpoint.c, infrun.c, sparcdep.c added
3810 remote_insert_breakpoint(), and remote_remove_breakpoint()
3811 to breakpoint.c instead of directly writing breakpoint instructions.
3812 * sparcdep.c on remote_debugging,there is no need
3813 to remove signle step breakpoint instructions.
3814 * main.c added "-epoch" flag and "int epoch_interface" to main.c
3816 * printcmd.c - epoch interface sends lisp expressions to open up
3817 epoch windows on inspection.
3818 * valprint.c - added arrayprint, and addressprint and made adding
3819 format controls easier
3820 * wait.h added a couple of undef's because we were getting
3821 complaints about WSTOPSIG and WTERMSIG begin redefined.
3824 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
3826 * symtab.c (decode_line_1): Add support for handling method stubs
3827 in the type information.
3829 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
3831 * values.c (baseclass_addr): Run loop from INDEX+1 to
3832 N_BASECLASSES; otherwise, we can still get into a loop.
3833 @@ This should be restructured to use a cleaner search strategy.
3835 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
3837 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
3838 abbreviation "Tt" for tags which have the same name as their
3841 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
3843 * symtab.c (list_symbols): add ability to set breakpoints on all
3844 the functions which match a particular regular expression.
3846 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
3848 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
3849 should print ANSI qualifiers (such as `const' and `volatile').
3850 All callers changed to call with ANSI == 1, except from
3851 `check_method_stub', which uses old-style syntax.
3853 * symseg.h (struct fn_field): Remove unneccessary `args' field.
3854 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
3856 * values.c (check_stub_method): New function.
3858 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
3860 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
3861 * valprint (type_print_base): Ditto.
3863 * symtab.c (gdb_mangle_typename): New function.
3865 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
3867 * breakpoint.c (catch_command): New function. Provides a
3868 mechanism to set breakpoints based on catch clauses.
3869 (disable_catch): Similar, but disables breakpoints on catch
3871 (delete_catch): Similar, but deleted breakpoints on catch clauses.
3873 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
3875 * blockframe.c (blockvector_for_pc): New function.
3876 * blockframe.c (block_for_pc): Changed to call
3877 `blockvector_for_pc' and get the block itself.
3879 * stack.c (catch_info): New function. Prints info about
3880 exceptions which can be caught in the current frame.
3881 * stack.c (print_frame_label_vars): New function. Similar to
3882 `print_frame_local_vars'.
3883 * stack.c (print_block_frame_labels): Prints out labels that are
3884 defined in this frame. These labels are exceptions that can be
3887 * dbxread.c: Updated to handle N_CATCH symtab types.
3889 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
3891 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
3892 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
3893 when printing the type.
3895 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
3897 * valprint.c (val_print): Use `baseclass_addr' to access the
3898 baseclasses pointed to via the derived class object at VALADDR.
3900 * values.c (baseclass_addr): New function. Casts derived pointers
3901 to baseclass pointers taking virtual baseclasses and multiple
3902 inheritance into account.
3904 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3908 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3910 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
3911 exp_valid_block field correctly.
3913 * infrun.c (wait_for_inferior): When checking "don't even think
3914 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
3915 also check step_resume_breakpoint.
3916 Insert breakpoints and continue (not step) if
3917 step_resume_break_address != NULL, even if another_trap.
3918 If trap_expected and we enter sigtramp, then set up a
3920 If trap_expected is set when we hit the step_resume_break,
3922 When calling resume and trap_expected says tell resume to step
3923 (2 places), also check step_resume_break_address.
3925 * infrun.c (wait_for_inferior): Don't set
3926 prev_{pc,sp,func_{start,name}} before calling wait ().
3927 Do set them after exiting loop.
3928 Move their declarations outside functions.
3929 (start_inferior): Initialize them.
3931 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3933 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
3934 Restore old code which distinguishes between trap_expected and
3935 running_in_shell, just make the latter take any non-TRAP signal,
3938 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
3940 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
3941 xconfig/3b1 (CC,PINSN_CC): Define.

3960 (printf_command): Add from_tty parameter.
3962 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
3964 * value.h: Add optimized_out field and change lazy field to
3965 char. Add macro VALUE_OPTIMIZED_OUT.
3967 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
3968 instead of stuffing things in buffers (oappend, etc).
3970 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
3971 execute_command, exit both loops.
3973 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
3975 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3977 * Makefile.dist (RAPP_OBS, rapp),
3978 rgdb.c, rserial.c, rudp.c, serial.c, udp.c, xdep.h,
3980 m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
3982 * valops.c (value_struct_elt), values.c (value_static_field):
3983 Change error messages to remove references to `info methods'.

3988 infrun.c (start_inferior): Add START_INFERIOR_HOOK.
3989 infcmd.c [SHIFT_INST_REGS]: New code.
3990 findvar.c (read_relative_register_raw_bytes): Return a value.
3991 infcmd.c (do_registers_info): Check value from
3992 read_relative_register_raw_bytes.
3994 * command.c (delete_cmd): Free the struct cmd_list_element(s)
3997 Mon Apr 23 10:42:21 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4000 findvar.c (get_saved_register): New function.
4001 findvar.c: Rewrite code which called find_saved_register to
4002 call get_saved_register instead.
4004 Sun Apr 22 14:47:51 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4006 * valprint.c (val_print): Change error message printed when
4007 the type has TYPE_FLAG_STUB set.

4020 (store_inferior_registers): Don't call read_register_bytes.
4021 symmetry-xdep.c (store_inferior_registers):
4022 #if 0 out code to fetch registers.
4024 * values.c (value_as_long): Call COERCE_ARRAY.

4033 * coffread.c (have_symbol_file_p): New function.
4034 * coffread.c [COFF_CHECK_X_ZEROES] [TDESC]: New code.
4035 * coffread.c (read_one_sym): If there is more than one
