1 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
4 tabs, which end up in the disassembler output inadvertently.
6 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
8 Make it compile cleanly in an ANSI GCC2 environment.
10 * blockframe.c: <stdio.h>
11 * cplus-dem.c: free takes a void *, ifdef __STDC__
12 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
14 * defs.h (alloca): Avoid doing anything if alloca already def'd.
15 * stddef.h, stdlib.h: Remove these files.
16 * symtab.c: Avoid declaring qsort, close.
17 * symfile.c: Avoid declaring close.
18 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
19 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
21 Assorted other changes.
22 * dbxread.c: include "libaout.h", not "liba.out.h".
23 * printcmd.c (print_frame_args): Set recurse properly for
24 indentation of struct and array parameters.
25 * valops.c (value_cast): Allow cast to void.
26 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
27 single_step() in a target-independent fashion.
28 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
29 set up to be ready to continue. This makes us target independent.
30 * infptrace.c (child_resume): Remove call to single_step; now
31 can single step a SPARC target of any kind.
33 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
35 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
36 docn into separate sections---basically chapters, plus two loose
37 pieces that can be configured to go in different places. This
38 allows GNU m4 to preprocess the manual without coredumping.
40 * Makefile.dist: tell TeX where to find texinfo.
42 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
44 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
45 the new target "rdl-apps.texinfo" which captures the Makefile
46 variable that records where to find the Readline libraries.
48 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)

53 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
55 * README: Update for release 3.95.
56 * config.gdb: Don't create readline dir in subdir builds.
57 * main.c: Include with "..." form for non-system include files,
58 so "gcc -MM" for "make depend" works.
59 Include readline files with "...h" rather than <readline/...h>.
60 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
62 * coffread.c: Undo minor damage done by Rich Pixley. Use
63 different internal and external representations of COFF
64 data structures. Use new BFD routines for swapping them in and
66 * symfile.c (free_named_symtabs): Avoid freeing file names that
67 are null or empty. Old i960 tools seem to produce files that
68 claim to have empty names, causing each successive file read
69 to blow away the previous one.
70 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
71 Move deferred_stores to top of file, but don't separate its
72 #define's from its variable. Add commentary.
73 * Makefile.dist: Fix Rich damage; undo "configure" changes in
74 favor of keeping the (working) config.gdb. Move readline

82 * tconfig/news: target depends on m68k-tdep too.
84 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
86 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
89 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
90 applied various small fixes due to or inspired by RMS comments
92 * doc/gdb.texinfo: finished using all RMS comments, save those for
93 appendices on readline and cmd history (which are in other source
96 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
98 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
99 chapter 9; (2) documented 'break' command's menu mode for
100 overloaded names, in response to hgs problem report C++ p-31
102 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
104 * doc/gdb.texinfo: (1) better introductory example; (2) more
105 consistent use of @code, @samp, @file, @kbd throughout; small
106 cleanups to first three nodes; (3) new "Contributors" node;
107 (4) Appendix, Renamed Commands; (5) divert specialized startup
108 instructions to "Targets" chapter for generic manuals, while
109 leaving them up front for manuals specific to specialized
110 environments; (6) apply fixes from RMS comments through chapter 4.
112 * pretex.m4: modify explanatory text slightly (and redefine
113 "regexp") to keep GNU m4 from complaining. (It still crashes
114 later, but one step at a time...)
116 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
118 * readline/readline.c (update_line): Avoid dereferencing a pointer
119 before comparing it to its bounds. Saber caught this.
120 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
121 and only set PC if tgetstr returned non-null. Saber caught this.
123 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
125 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
126 stuff for config manual) here where it counts; updated
127 to use new subdir structure (gdb/doc/).
129 * Makefile: generated from above via
133 * gdbint.texinfo: added instructions on generating gdb.info* files
134 locally for release. These are ordinary info
135 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
136 Makefile)---but due to use of texinfo 2, can't count on makeinfo
137 to generate these, so we distribute them already formatted.
139 * gdb.texinfo: included full Info node and menu crud (as generated
140 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
142 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
143 put in comments-for-future gdb.info target (one day makeinfo will
146 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
148 * gdb.texinfo: Updated to include new or old undocumented
149 commands, at least the following (perhaps some others I forgot to
150 record): info f, info float, info path, info program, info s, info
151 set, info source, info terminal, info types, info user, set/show
153 Also covered all recent GDB command renames for v4.
155 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
157 * mipsread.c: Rather than keeping count of how many symtabs
158 and psymtabs we have, for sorting purposes, count them when
159 we need to sort. This fixes bug in rereading of symbol tables.
161 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
163 * infcmd.c: renamed "info path" to "show paths"

178 symtab.h, target.c, target.h: Lint.
179 * core.c: setup and select frame after reading shared libs,
180 else reading shared libs will clobber them. Lint.
181 * utils.c (error): Force out any buffered wrap text.
183 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
185 * remote.c: Remove decls of memory_insert_breakpoint
186 and memory_remove_breakpoint, no longer used. (Suggestion of
189 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
190 to make it easier to interface to "configure"'d libraries.
192 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
194 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
195 aliases for set/show print.

703 * target.h: Add to_doc and target_preopen.
704 target.c: Add target_preopen and target_command.

743 Permit symbols to be superseded when new symbol files have
744 been read in, particularly for VxWorks.
746 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
747 to the main file, as well as to include files. Also, put global
748 functions into the global psymtab, to make "i fun" work.
749 (end_psymtab): Free named symtabs and psymtabs for a file, once a
750 new psymtab for it has been read.
751 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
752 a file, once a new symtab has been read for it.
753 * mipsread.c: FIXME. We need to do the same for MIPS, but it
754 looks harder to determine the top-level block before it's been
755 queued to the psymtab list.
757 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
758 If we have wiped out any old symbol tables, clean up at end of
760 (symbol_file_command): Don't reference symfile_fns if it's zero.
762 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
763 defines for the blocks of a blockvector that contain global and
764 file-static symbols and the first of the smaller scope contours.
765 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
766 decode_line_1, make_symbol_completion_list): Use the above.
767 * coffread.c (end_symtab, patch_opaque_types): Ditto.

773 * symtab.c (list_symbols): Process the first symbol of the
774 static psymbols list.
775 (types_info): Restore this function from its untimely #if 0.
776 It's not perfect, but it is better than nothing.
777 (_initialize_symtab): Restore "info types".
779 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
781 * m68k-stub.c: Remote stub for 680x0's, created from
782 rem-m68k.shar (which is removed).
783 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
784 Remove RCS log stuff now that we use CVS and it blows our diffs.
786 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
788 * symmisc.c (free_named_symtab): Make it work, in its current
789 kludgy fashion. Change result to indicate if we blew away bkpts.
790 * dbxread.c (end_symtab): Accumulate result from
791 free_named_symtab and print warning if we blew user's state.
792 * symfile.h: free_named_symtab now returns an int.
794 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
796 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
797 is the first symbol read, even if not mainline.
798 (dbx_psymtab_to_symtab): symfile might be zero, cope.
799 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
800 (set_section_command): New command ("section xxx yyy" -- should
801 be renamed to "set section xxx yyy" FIXME) which sets the
802 base address of a section of the exec file, overriding the
803 virtual address that BFD reports.
805 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
807 * exec.c: Add add_syms_addr_command to exec_ops, so you can
808 load symbols at any address while examining an exec file.
810 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
812 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
813 for printing the float info is host-dependent, not
814 target-dependent. FIXME.
815 * i386-pinsn.c: Move #includes to top, remove useless ones.
816 * i386-tdep.c: Don't bother including <.../reg.h> since we
817 don't use it (and it doesn't exist on host systems).
819 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
820 Convert negative numbers properly.
821 (ieee_test): Make numbers really random; fix format arg.
823 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
824 * core.c (core_detach): Unpush core_ops, which might not be on
825 top. We used to just pop the top, which broke things. Don't
826 need dont_repeat() any more.
827 (core_file_command): Psst! Don't repeat it.
828 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
829 * expprint.c (print_subexp): Avoid switch fallthru on
830 BINOP_ASSIGN_MODIFY, so we can print += and such.
832 * inflow.c (kill_command): After killing inferior, print our
833 current frame in the core file, if we have one.
834 (generic_mourn_inferior): When inferior dies, either select
835 the current frame (in the new target, e.g. core file), or
836 set both the current and selected frames to NULL.
838 Changes from Peter Schauer.
840 * infptrace.c: Avoid <sys/ptrace.h> on USG.
842 * Make all file names fit in 14 characters (sigh and damn!):
843 mv hp300hpux-xdep.c hp300ux-xdep.c
844 mv symmetry-xdep.c symm-xdep.c
845 mv symmetry-tdep.c symm-tdep.c
846 mv convex-opcode.h convx-opcode.h
847 mv tm-vxworks960.h tm-vx960.h
848 mv tm-vxworks68.h tm-vx68.h
849 mv Makefile.srcdir Makefile.sdir
850 mv gdb-int.texinfo gdbint.texinfo
851 mv remote-sa.m68k.shar rem-m68k.shar
852 mv remote-multi.shar rem-multi.shar
853 * Makefile.dist, README, config.gdb, convex-pinsn.c,
854 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
855 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
858 * command.c (user_info_1, user_info): New command for listing
859 the user-defined commands.
861 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
863 * dbxread.c (really_free_pendings): Clear file_symbols
864 and global_symbols after freeing them; otherwise, running
865 this function twice (if it appears twice on the cleanup
866 chain), we try to free things twice.
868 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
869 based on text_addr (the address of text in core), not on addr (the
870 offset between text in the .o file and in core). This change
871 is from Peter Schauer.
873 * main.c: Define ALL_CLEANUPS as a cast of zero.
874 (return_to_top_level): Use it.
875 (main): Do all cleanups after each command run as part
876 of the gdb startup sequence. Also do all cleanups before
877 entering the command loop, and every time we exit the command
878 loop and reenter. Before, the cleanups from the startup sequence
879 were being left undone until the first error!
880 (command_loop): Rename do_nothing cleanup to command_loop_marker
881 so we can see it easily when examining the cleanup chain.
882 (init_signals): Add another do_nothing for signal handling.
883 (quit_command): Only try to kill target if it has execution.
884 Problems in the target stack got us into a state where
885 inferior_pid was nonzero but none of the targets had execution.
886 In this state you couldn't exit gdb.
888 * dbxread.c: Two changes from Peter Schauer.
889 (echo_command): Fflush output after an echo command.
890 (show_history): Pass all args to cmd_show_list.
892 * utils.c (init_malloc): Call mtrace to turn on tracing
893 if the environment variable MALLOC_TRACE is set to a file name.
894 * mtrace.c: Add source file which provides a log of every malloc,
895 free, and realloc to a trace file.
896 * mtrace.awk: Add source file which analyzes the trace file.
897 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
898 (VERSION): Roll to 3.94.3.
900 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
901 (check_duplicates): Don't bother with watchpoints.
902 (set_raw_breakpoint): Comment about danger of this routine.
903 (watch_command): Parse and eval all args before calling
906 * solib.c (find_solib): Avoid error in referencing memory to
907 see if any more shared libraries have been added. This is
908 particularly useful if the target has terminated. Bug reported
911 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
912 in bringing up 3.94.2 on the Sun-3.
914 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
915 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
916 expression (in scope) before reenabling watchpoint.
917 * signame.c (init_sigs): Add missing declaration of i, fix
918 sys_siglist declaration.
919 * source.c (list_command): Fixed range computation to use
921 * stack.c (backtrace_command): Do not allow command if target has
922 no stack, print informative error message.
923 * target.c (target_command): Do not write into command line
924 because this fails if the target command is used in a user defined
925 command. [This change was enhanced by gnu to support any-
926 unique-prefix matching on target names.]
927 * valops.c (value_struct_elt): Avoid infinite loop on an
928 erroneous attempt to print the member of function (try p main.p).
930 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
932 * expread.y (name_no_typename): Avoid reduce/reduce errors
933 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
934 Since the GDB parser really doesn't use name_no_typename in a
935 name-only context, the parser can't tell the diff between
936 names and numbers here. Avoid allowing a name_no_typename
937 to be a NAME_OR_*INT to resolve the conflict.
939 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
941 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
943 * valprint.c (val_print_fields): bitfield printing didn't handle
944 byte order. Indirect through a few more fns to cope.
946 * values.c (modify_field): also cope with byte order.
948 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
950 Cleanup for release 3.94.2:
952 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
953 include files. Roll version to 3.94.2.
955 * coffread.c (init_stringtab): Read length into unsigned char
956 array before swapping; don't assume 32-bit longs.
958 * target.c (target_info): Don't bother with get_sym_file, just use
959 the symfile global variable.
960 * symtab.h, symfile.c (get_sym_file): Delete it.
962 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
963 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
964 (read_type): Replace one more error() with complain().
966 * mipsread.c (parse_partial_symbols): Replace printf with complain.
968 * i960-tdep.c: Fix copyright attribution.
970 * config.gdb: Quote all backquotes in doublequotes. You can
971 quote me on that. BSD 4.4 shell found this one.
973 * infptrace.c (throughout): The third argument to ptrace is an
976 * infrun.c (wait_for_inferior): When program has terminated, we
977 have to call target_terminal_ours before we pop that target off
978 the stack (e.g. before a call to target_kill or
979 target_mourn_inferior). This fixes problem where a program
980 terminates, then GDB stops for (tty output) and you have to type
981 "fg" to the shell to resume it. FIXME: This code for what to
982 do after termination really should be in normal_stop instead.
984 * gdbcore.h (read_memory_check): Change declaration; it changed
987 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
988 4.4 prereleases, this avoids a bug in their sgtty compatability
990 * remote.c: Use terminal.h rather than hand-rolling the same.
992 * signame.c, signame.h (psignal): Arg is unsigned, not int.
993 * utils.c (strsave, strstr): Fix arg types.
994 * valprint.c (val_print): lint
996 MIPS symbol table support from Per Bothner:
998 * symfile.c (symtab_fns): Remove initializer table that needs to
999 be hacked for each new symbol file format supported.
1000 (add_symtab_fns): New function, chains symbol table
1001 handlers into the global list.
1002 (symfile_init): Search this list.
1003 * symfile.h: Add next pointer, declare add_symtab_fns.
1004 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1005 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1007 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1008 symbol *). Thus, we no longer need the hack to trash
1009 pst->filename. Good, since that hack confused code in symfile.c!
1011 (reorder_symtabs, destroy_all_symtabs): Removed static
1012 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1013 Instead, the latter now uses a temporary array (stack-allocated
1014 from an obstack, and then freed).
1016 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1017 haven't been set in the outermost stBlock of a procedure. This was
1018 a problem with f77 binaries on Ultrix 4.?.
1020 (new_symtab, new_symbol, new_type): Continue changing code to use
1021 obstacks more and otherwise conform to dbxread internal style.
1022 Made the free_code of symtabs be free_linetable (as in dbxread)
1023 instead of free_contents. This implies memory leaks when reading
1024 a new symbol table, until the conversion is finished. Did change
1025 (struct symbol) and (struct type) to be allocated on the
1026 symbol_obstack. Blocks and blockvectors are among the things
1029 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1030 tested much, but it solved one problem (reported by Meissner), and
1031 cleans up some other things. The problem happened when an
1032 included file contains actual code (functions) and not just
1033 definitions. The mips coff is a little inconvenient there, since
1034 it may cause a procedure to be mapped to the wrong psymtab.
1036 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1037 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1038 this will need work for the new core paradigm.
1040 Opcode patches from the net:
1042 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1043 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1044 missing altogether - they are added here. From Bruce Bauman.
1045 * mips-opcode.h: The low mask for C0 instructions was too small.
1046 From Garrett Lau. I modified the fix to check the entire 32-bit
1049 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1052 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1054 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1056 * dbxread.c (read_type): Pointer subtraction (value_sub in
1057 valarith.c) sometimes failed because the types of the
1058 pointers being subtracted were not identical.
1059 These differed because dbxread.c was allocating pointer types
1060 using dbx_alloc_type+smash_to_pointer_type instead of
1061 lookup_pointer_type. I failed to find a justification for the
1062 former, so I changed it to use the latter. Similarly, I
1063 replaced smash_to_function_type by lookup_function_type,
1064 and smash_to_reference_type by lookup_reference_type.
1066 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1067 _initialize_mipsread): corresponding changes.
1069 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1071 * source.c (mod_path): Do tilde_expand on each component of the path,
1072 rather than on the (list of) paths as a whole.
1073 (print_source_lines): Set first_line_listed in addition to
1074 current_source_symtab and current_source_line. If the source was
1075 not findable, after a "dir" command to fix the problem,
1076 a "list" would get the wrong lines.
1078 While I was there... (gnu):
1080 * dbxread.c (read_type): Change error to complaint.
1082 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1084 First attempt at detailed understanding of symbol table memory alloc.
1086 * dbxread.c (dbx_symfile_read): Free our string table if we
1087 aren't the mainline. Free the "info" struct since we're done with
1089 (init_psymbol_list): Free any previously allocated psymbol lists.
1090 (): FIXME: Should realloc-down the psymbol lists when done reading
1091 the main symbol file?
1093 * symmisc.c (free_symtab): Free fullname field too.
1095 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1096 (REGISTER_ADDR): Make result type unsigned int.
1098 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1099 define REGEX must also define REGEX1 (its dependency).
1101 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1103 * tconfig/i960: No longer works, points you at vxworks960 or
1106 * xgdb.c, XGDB-README: Remove file. Users can get the much
1108 * Makefile.dist: Remove all trace of xgdb.
1110 * breakpoint.c (breakpoint_1): Pass demangle arg to
1111 print_address_symbolic.
1112 (clear_breakpoints): Remove unused function.
1113 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1114 (breakpoint_re_set): Use catch_errors to do them all anyway.
1116 * gdb-int.texinfo (Host versus Target): Add section on what is
1117 a "host" feature versus what is a "target" feature.
1119 * infcmd.c (path_command, path_info): Handle the PATH variable
1120 (object search path) as conveniently as the source search path.
1121 * environ.c (set_in_environ): Set some vars in GDB's environment,
1122 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1123 * source.c (mod_path): New function, from guts of
1124 directory_command, modifies a path. Used by path_command.
1125 (directory_command): Call it.
1126 * defs.h (strsave): Declare.
1128 * utils.c (sevenbit_strings): Add new printing option.
1129 (printchar): Use it.
1130 (strsave): Provide this handy helper routine.
1131 (set_width_command): Rename set_screen_width_command.
1132 (_initialize_utils): "set screen-width" => "set width";
1133 "set screen-height" => "set height"; add sevenbit-strings.
1135 * infcmd.c (do_registers_info): Print floating point registers
1136 in raw hex as well as float format, regardless of whether it is
1137 a "virtual" convertible register.
1138 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1139 regs as a double, just in case it's being used that way.
1140 * values.c (unpack_long): Comment on array/function coercion.
1141 (unpack_double): Argument is in target byte order now. For
1142 integer arguments, just call unpack_long and float the result.
1143 * m68k-tdep.c: include defs.h for "const" handling.
1144 * remote-nindy.c: Use ieee-float stuff.
1145 (nindy_fetch_registers): Unpack double regs to host double, then
1147 (nindy_store_registers): Pack extendeds to host double, flip
1148 around by misusing unpack_double, send as target double.
1150 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1151 zero, as when stopped at the first instruction of a process.
1153 * blockframe.c: Fix filename in comment (param.h => tm.h).
1154 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1155 * tm-68k.h: Fix typos.
1157 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1159 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1161 * coredep.c (fetch_core_registers): Pass end-address of register
1162 section to register_addr as expected. Don't call supply_register
1163 if we'd just pass it garbage.
1165 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1167 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1169 * target.c (push_target, target_info): Cast enums to int for < or
1172 * stack.c (print_frame_info): Identify source file & line
1173 even if we can't print it.
1175 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1177 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1179 Clean up IEEE floating point support.
1181 * ieee-float.h: New file.
1182 * ieee-float.c: Write real routines to convert between host
1183 doubles and various target IEEE extendeds.
1184 * m68k-xdep.c: Eliminate assembler code for extended floats.
1185 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1186 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1187 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1188 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1189 double_to_ieee_extended.
1190 * i960-tdep.c: Define ext_format_i960.
1191 * m68k-tdep.c: Define ext_format_68881.
1192 * sparc-tdep.c: Define ext_format_sparc, though unused.
1193 * Makefile.dist (HFILES): Add ieee-float.h.
1194 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1197 Obsolete the "coffstrip" program in favor of using BFD's strip.
1199 * nindy-share/coffstrip.c: Remove file.
1200 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1201 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1202 * tconfig/nindy960: Remove reference to coffstrip.o.
1204 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1206 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1208 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1209 * dbxread.c: Remove static symfile_bfd.
1210 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1212 * inftarg.c (child_detach): Pop the child_ops vector if the
1213 detach is successful.
1214 * remote-nindy.c (nindy_create_inferior): Don't push a new
1215 nindy_ops since nindy uses the same one for execution and memory
1217 * core.c (core_ops): Use child_attach and child_create_inferior
1218 rather than default attach and create_inferior functions.
1220 Handle floating point registers in core files.
1222 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1223 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1224 This version untested since BFD doesn't yet support sun3 core
1226 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1227 conventions. Fix comments and style. This version has not
1228 been compiled yet, since we have no HP inhouse.
1229 * core.c (get_core_registers): Look for two sections, ".reg"
1230 and ".reg2", and pass both to fetch_core_registers sequentially.
1232 Revise directory path yet again.
1234 * source.c (forget_cached_source_info): Not static any more.
1235 (init_source_path): New default source path is "$cdir:$cwd".
1236 (dir_command): Handle variable arguments ($cdir, $cwd).
1237 (source_info): Print "Compilation directory" rather than
1238 "Originally compiled in" to remind people of $cdir.
1239 (openp): If the path contains $cwd, use current directory.
1240 (open_source_file): If compilation directory is known, replace
1241 first $cdir in path with the compilation directory.
1242 (print_source_lines): Even if we can't print the lines, set the
1243 current symtab and line for future commands like "info source" or
1244 "breakpoint". Also, error message now contains the file name,
1245 line number, and file access error message.
1246 (_initialize_source): Fix help text to describe changes.
1247 * main.c (cd_command): Forget cached source info when we chdir.
1248 * utils.c (strstr): Add simple implementation.
1250 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1252 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1253 Byte-swap COFF symbol tables if necessary when reading them in.
1254 Use complain() to replace error message in one spot. Needs
1255 corresponding change in bfd/coff-code.h to make some symbol
1256 swapping routines non-static.
1258 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1260 Merge changes from Eirik Fuller, for UTek.

1263 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
1264 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1265 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1266 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
1267 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
1268 declarations of errno.
1270 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1272 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1273 <rpc/rpc.h> and <rpc/types.h>.
1275 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1277 * i960-tdep.c (examine_prologue): Add new argument limit,
1278 which stops the scan at the end of the prologue, or at the PC.
1279 This fixes a problem where it walks down into the code for the
1280 user's statements if that code looks like function prologues.
1281 Mark Fox and I have been bouncing this code back and forth, making
1282 small changes to it. Callers changed to match.
1284 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1286 Cleanup for gdb-3.94 release final:
1288 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1289 the .c files from vx-share and nindy-share, from the various
1290 macros, since they are not found via ALLDEPFILES.
1291 (SFILES): Add tm-i960.h.
1292 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1293 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1295 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1296 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

1300 * am29k-tdep.c: Add contribution line.
1301 (examine_prologue): Cache information about function prologues in
1302 the misc-function-vector to avoid lots of references over the
1303 serial line while examining instructions.
1305 * core.c (core_close): New function made from cleanup_core.
1307 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1308 remote-vx.c, remote.c, target.c, target.h,
1309 Update target_ops vector to add attach, close, and load entries.
1310 Use add_syms_addr_command, not add_file_addr_command, for
1311 add_file. Break out close routine from existing code.
1313 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1314 they are in an obstack.
1315 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1317 (define_symbol): Add symbol type parameter; change callers;
1318 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1319 it to influence the symbol class on the i960.
1320 (define_symbol): Swap LOC_CONST's into target byte order.
1322 * exec.c (exec_close): New function.
1323 (exec_file_command): Call it.
1325 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1326 Fix byte order of frame pointer.
1327 (read_var_value): Result of 0 if var's value can't be found,
1328 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1329 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1330 (locate_var_value): Use read_var_value and use its lazy address
1331 as the location of the var's value. Lint.
1333 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1336 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1337 obsolete Intel versions in favor of vxgdb versions.
1338 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1339 code dealing with byte order of values, which Intel did in host byte
1340 order rather than gdb-4's target byte order.
1341 (i960_frame_chain_valid): Move to nindy-tdep.c.
1342 (examine_prologue, skip_prologue, frame_find_saved_regs,
1343 frame_args_address, leafproc_return, saved_pc_after_call,
1344 pop_frame): Add vxgdb versions from Mark Fox.
1345 (examine_prologue, frame_struct_result_address): Add code
1346 to deal with the saved value of G13 (struct return address
1348 (frame_args_address): Modify Mark's version to prefer the
1349 saved value over the current value in the topmost frame.
1350 Cache result in the frame info to avoid performance hair in
1352 (print_fault): Add gdb960 code for printing faults.
1353 (_initialize_i960): Actually call check_host.
1355 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1356 add stub routines. FIXME, these currently just return zero!
1358 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1359 (attach_command): Call target_attach, not target_open, now.
1361 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1362 (child_attach): Rename from child_open.
1363 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1364 don't confuse it with a zero step_resume_break_address.
1366 * inftarg.c (child_detach): Eliminate inferior_pid test.
1367 (child_files_info): Clean up message a bit.
1368 (child_ops): Use child_attach, not child_open, to attach.
1370 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1371 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1372 findvar.c to here, since it depends on the contents of the
1373 shadow_contents of breakpoints, but keep if #if 0 since it is
1376 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1379 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1380 (ptype_command, display_command): Eliminate have_inferior_p and
1381 have_core_file_p in favor of target_has_stack or
1382 target_has_execution.
1383 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1384 code for actually finding the values of arguments, though we still
1385 keep track of the maximum stack offset for use in printing unnamed
1386 arguments. Handle missing FRAME_ARGS_ADDRESS.
1388 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1389 (struct nindy_regs): Define registers passed to/from nindy.
1390 (nindy_fetch_registers, nindy_store-registers): Translate between
1391 nindy and GDB formats for the registers.
1392 (dcache_init): Statically allocate the cache, since it was being
1393 allocated by a malloc that was never freed anyway.
1394 (nindy_create_inferior): Error, not core dump, if no exec file.
1395 (nindy_before_main_loop): Use target_load, not target_add_file.
1397 * remote-vx.c (net_load): Specify large timeout for load
1398 requests. Allow user to break out with INTERRUPT.
1399 (net_break): Remove useless code, clean up. Change callers.
1400 (parse-args, skip_white_space, find_white_space): Clean up arg
1401 parsing to cope with quoted strings.
1402 (net_wait, net_quit): Never call error, just return status.
1403 (vx_read_register, vx_write_register): Cleanup status checking.
1404 #ifdef the code based on which CPU we are using (960 or 68k),
1405 FIXME, this should be completely general but it isn't yet.
1406 (vx_xfer_memory, vx_resume): Cleanup status checking.
1407 (vx_run_files_info): Improve message.
1408 (vx_load_command): Renamed from vx_add_file_command. Allow load
1410 (net_ptrace): Remove unused routine.
1411 (vx_wait): Adopt code from vxgdb960 to cope with broken
1412 connections to target machine and prompt to disconnect. Remove
1413 debug printouts. Map some EVENT_'s to SIGnals.
1414 (add_symbol_stub, vx_open): Print names of object files we found,
1415 and "ok" if we read their symbols OK. Clarify output in general.
1416 (vx_attach, vx_detach, vx_kill): Add these commands.
1417 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1418 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1419 "info files" output, and create_inferior, since we already have
1422 * stack.c (frame_info): Replace Frame_unknown with 0.
1423 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1424 (return_command): Pop until the PC matches as well as the FP,
1425 so it works even if the FP is shared with another function,
1426 as in "frameless" or "leaf" procedures.
1428 * symfile.c (load_command): renamed from add_file_target_command.
1429 (add_syms_addr_command): renamed from add_file_addr_command.
1430 (add_syms_command): Stub to call target_add_syms.
1431 (_initialize_symfile): Change command names and descriptions,
1432 add-file => add-syms, and load from alias to its own command.
1434 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1435 maybe_kill_then_create_inferior): Default for attempts to start
1436 a process, if one is already running, is to ask about killing
1437 it and retry if yes.
1438 (upstack_create_inferior): #if-0 it, strata obsolete it.
1439 (push_target, unpush_target, pop_target): to_close() a target
1440 before unstacking it.
1441 (target_info): Renamed from target_files_info.
1442 (_initialize_targets): Rename "i files" as "i target", accessible
1445 * target.h: Improve comments about the target_ vectored routines.
1447 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
1448 Convert commenting style to standard GNU style.
1449 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
1450 (SKIP_PROLOGUE): No longer a no-op.
1451 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1452 (*_REGNUM): Sort register numbers.
1453 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1454 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1455 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1456 are now 10 byte extendeds, not 8 byte doubles.
1457 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1458 for nindy versus vxworks targets. FIXME, this should possibly go
1459 in the target vector.
1460 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1461 frame_saved_regs and arg pointer with each frame.
1462 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1463 (FRAME_ARGS_ADDRESS): Use cached result.
1464 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1465 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1466 (PRINT_RAMDON_SIGNAL): Call print_fault.
1467 (POP_FRAME): Now works.
1469 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1470 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1471 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1472 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1475 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1476 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1478 * valarith.c (value_subscripted_rvalue): Avoid handling
1479 floats and doubles specially; it gave alignment errors. Lint.
1481 * valops.c (value_of_variable, value_of_this): Error if unknown
1484 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1485 to avoid alignment problems.
1486 (value_print): Handle unknown value address.
1487 (cplus_val_print): Two args are ignored; remove them. Change caller.
1488 (val_print): Use unpack_long rather than pointer-deref.
1491 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1492 to avoid alignment problems.
1493 (value_being_returned): Error if return value unknown.
1494 (set_return_value): Add bogosity warning, FIXME. *
1496 * TODO: A woman's work is never done.
1498 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1499 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1500 Add ieee-float.o to OBS.
1501 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1502 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1503 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1505 Changes to generalize the VxWorks RPC protocol slightly, to handle
1506 i960 as well as 68000.
1508 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1509 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1510 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1511 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1512 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1513 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1514 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1515 so they will move in target byte order rather than network
1516 byte order (happens to be the same).
1518 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1520 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1522 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1525 Add contribution lines to various files, showing where they
1528 * breakpoint.c (break_insn, check_break_insn_size,
1529 read_memory_nobpt): Remove to mem-break.c.
1531 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1534 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1535 entry has bad register number. This change is not
1536 tested in this release, FIXME.
1538 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1541 * value.h: Force value's contents field to be aligned to hold
1542 at least a double or a long long (if supported). This avoids
1543 doing bcopy's in and out of the contents field.
1545 (step_1): Avoid coredump under obscure circumstances when we
1548 * symtab.h (misc_info): Add field to misc function vector for
1549 any kind of cached information the target code desires. AMD
1550 29000 uses this to avoid repeating examine_function_prologue's.
1552 * coffread.c: Lint. Remove static symfile, read_section_header.
1553 core.c (have_core_file_p): Lint: remove.
1554 expprint.c (print_subexp): Lint.
1555 infptrace.c, valops.c, valprint.c: lint.
1557 Roll in changes from vxgdb-5.0.1:
1559 * symtab.h: Comment byte order of each address class. Add
1560 LOC_LOCAL_ARG for frame-relative args (960).
1561 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1562 symtab.c, symmisc.c: ditto.
1564 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1566 * remote.c (remote_resume): Error if resume with a signal.
1568 * symfile.c (prim_record_misc_function): Clear misc_info.
1569 (fill_in_vptr_fieldno): Check stub type of arg.
1571 * valops.c (value_cast): Avoid looking up names of types whose
1572 name we don't know, to prevent coredump. Sun CC produces typedef
1573 rtx and the name of *rtx is zero...
1575 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1577 Roll in changes from final AMD 29000 port (Tiemann).
1579 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
1580 for ../include/a.out.encap.h. This might not work now that BFD
1581 is separately compiled. Instead, BFD support for encap will have
1582 to translate machine type 29k into the right COFF_MAGIC.
1584 * infcmd.c: Remove references to inferior_pid that aren't used
1585 in actual ptrace calls; use target_has_execution, etc.
1586 (have_inferior_p): Remove function.
1587 (program_info): Print target info rather than "process number";
1588 avoid gratuitous messages unless from_tty.
1589 (run_stack_dummy, finish_command): Set proceed_to_finish.
1590 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
1591 main.c: Lint. Lose have_inferior_p().
1592 inferior.h (have_inferior_p): Remove, lint.
1593 (proceed_to_finish): Add flag to ask that all regs be saved
1594 by normal_stop, for the few commands that need it, speeding up
1595 serial I/O. Add comments to stop_registers.
1597 * remote-eb.c: Remove newline from breakpoint message we grep
1598 for. Never time out when running the user program.
1602 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1604 Roll in changes from vxgdb-5.0.1:
1606 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
1607 symbol in its raw form, we are processing an unlinked ".o" file.
1608 See if the target environment has assigned it an address, using
1609 target_lookup_symbol (VxWorks does), and enter it into the symtab
1612 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
1613 68k versions for a simpler version that assumes zero FP at bottom.
1614 Fixes bug of truncated stack reports.
1616 * target.h (target_lookup_symbol): Define this routine's args
1617 and result, finally.
1619 * target.c (nosymbol): Default routine for target_lookup_symbol.
1620 (target_default): Default lookup_symbol and call_function too.
1621 (files_info): Only print has_all_memory warning if a non-dummy
1624 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
1625 vx_convert_from_virtual): If target does not have floating point,
1626 zero register "values", and avoid doing cross-net conversions.
1627 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
1628 (vx_open): Rearrange code that attaches to target and reads
1629 symbols for all loaded modules, to work if some of the modules
1630 are not accessible. Add symbol_stub() and add_symbol_stub()
1631 as callbacks from catch_errors(). Allow connect attempt to be
1632 interrupted painlessly with ^C (FIXME, there are still some bugs
1633 if the interrupt happens during symbol reading.). Print
1634 final message with puts_filtered, since symbol messages are
1639 * main.c (catch_errors): Only print errstring if non-null.
1640 (command_loop): Avoid an ioctl per command to test ISATTY.
1642 * remote-vx.c (net_load): make static; avoid sophomoric msg.
1643 (vx_xfer_memory): Return correct result!
1644 (vx_files_info): Indicate whether target has float or not.
1645 (vx_lookup_symbol): Complain, not error, if target gone.
1646 (vx_open): Print "Connected" msg before disabling immediate-quit.
1647 [FIXME: lookup_symbol and vx_open changes need testing.]
1649 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
1650 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
1651 contributor lines and update copyrights to 1991.
1653 Changes from an attempted H-PUX host port:
1655 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
1656 defines PT_ATTACH and PT_DETACH but not PT_KILL.
1657 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
1658 * remote-vx.c: include <sys/time.h> for HPUX.
1659 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
1660 "core_file_command" routine to BFD regime. May not work yet.
1662 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
1664 * xgdb.c: Replace X10 version with some VJ version.
1665 (FIXME: Its copyright assignment is not on record.)
1666 * xgdb.c: Update include files to X11R4 (Xaw crud).
1667 (xgdb_display_source, create_text_widget): fix call to
1668 get_filename_and_charpos. Rewack source window stuff for X11R4
1669 (gleaned from include files, and "nm's" of binary libraries, since
1670 I had no doc available).
1671 (append_selection, append_selection_word): Disable with FIXME
1672 since R4 changed interface here.
1673 (create_buttons): Add back the old set of buttons.
1674 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
1676 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
1677 Roll VERSION to 3.94 (not yet final though).
1679 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1681 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
1682 obstack_int_grow, obstack_int_grow_fast): Eliminate
1683 cast on left of assignment, which gives MIPS cc fits and is
1686 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
1687 F_ALIAS. Use printf, not fprintf, when not passing a file
1689 (compare_opcodes): Check that identical instructions have
1690 identical opcodes, complain otherwise.
1692 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
1693 was reported by Roland McGrath.
1694 (unimp): Only match if exactly zero instruction. (Roland)
1695 (branches and traps): Generate all variations of these
1696 instructions with macros, based on a single call that defines
1697 each condition name and its binary representation.
1698 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
1700 * valprint.c (val_print_fields): Take, and use, format parameter.
1701 This means that "p/x struct" again prints the elements in the
1702 desired format. Changed callers.
1704 * stack.c (frame_info): Use filtered output, and indicate wrap
1705 points. Remove kludgy formatting designed to avoid line wrap.
1707 * utils.c (wrap_here): If the line is already full (because
1708 we had printed a long indent or long wrapped string), do an
1709 immediate newline-and-indent.
1711 * m68k-pinsn.c (print_insn_arg): Bugfix from
1712 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
1713 instruction is incorrectly disassembled as bkpt #8.
1715 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
1716 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
1717 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
1718 and then will dump core (sometimes). I traced it back to an
1719 uninitialized symfile_name in psymtab_to_symtab.
1720 (const_vol_complaint): Add quotes to message.
1721 (define_symbol): Only believe line number if gcc_compiled.
1722 Avoid allocating symbol if we will not return it.
1724 Add target strata support so that newly established targets go
1725 into their right place in the target stack (e.g. a new exec file
1726 doesn't wipe out the ability to access the running process).
1728 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
1729 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
1730 and initialize it properly in all the targets.
1732 * target.h: Document strata. Change return type of push_target.
1734 * target.c (nomemory): new function for dummy memory access.
1735 (tcomplain): Rename complain, now also used in symfile.c.
1736 (push_target): Push targets within strata. New return value shows
1737 whether new target is on top of stack or not. Always keep dummy
1739 (target_files_info): Ignore dummy target.
1741 * core.c (core_open): Warn user, and skip accessing file, if the
1742 core target is not the topmost target in the stack.
1743 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
1746 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
1747 target_ops, it doesn't belong there since we have no regs there.
1748 Change name of target from machine => memory to clarify.
1750 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
1752 * Freeze version 3.93 for release.
1754 * Makefile.dist: Handle vx-share and nindy-share subdirs
1755 properly when building gdb.tar.Z.
1757 * symtab.c: lint; add no_symtab_msg to consolidate the messages
1758 printed in various places, so I could change just one copy.
1760 * dbxread.c, coffread.c: Change references to bfd->iostream
1761 to cast to FILE *, now that BFD avoids needing types defined
1762 in other header files.
1764 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1766 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
1767 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
1768 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
1769 (actually gcc -Wall).
1771 * dbxread.c: Remove first_global_sym, last_global_sym, since
1772 they are never referenced.
1774 * defs.h (baud_rate): Declare.
1775 main.c: Define it, and add the -b option to set it.
1777 * gdb-int.texinfo: Add text on how to define a new host or target
1778 architecture, prompted by Per Bothner's questions about MIPS
1781 * gdb.texinfo: Document "complaints". Change doc of -q since
1782 gdb no longer prints the copyright and blurb if you specify a file
1783 name to be debugged (just like Emacs). Add doc for Nindy-specific
1784 command line flags for specifying target serial port and such.
1785 Update copyright to 1991.
1787 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
1788 has taken over for us the job of ripping up executable files. The
1789 crud caused Per Bothner's port to not compile.
1791 * infrun.c (normal_stop): Avoid printing "Program exited
1792 normally" if we are in batch mode. This allows a GDB which
1793 executes a program on a target system, to behave like a Unix
1794 command (input from stdin, output to stdout, no extraneous
1797 * main.c (main): Allow additional machine-dependent command line
1798 options to be specified with the ADDITIONAL_OPTIONS,
1799 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
1800 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
1801 processing to occur just before the main loop with
1802 BEFORE_MAIN_LOOP_HOOK.
1803 (main): If a "core file" argument is specified, and it is not a
1804 core file, try it as a process ID to attach.
1805 (symbol_completion_function): Attempt to cope with
1806 "show screen-" TAB, not very successfully. This needs more work,
1808 (batch_file): New function, returns whether we are reading
1809 commands from an interactive tty on stdin, or from somewhere else.
1810 Called by normal_stop since it doesn't get from_tty passed down
1811 to it like many commands do.
1813 * remote-nindy.c: Handle command line options for nindy
1815 (nindy_before_main_loop): Prompt user for tty name if they
1816 don't specify it before getting to the interactive command loop.
1818 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
1819 and -r command line options. Also add hook before main loop
1820 to make it easy to specify a tty.
1822 * TODO: More things to do, one done.
1824 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
1826 * dbxread.c: Make complaint() calls pass pointer, not struct.
1827 Add complaints about badly formatted C++ type information
1828 (const/volatile indicator, and parse errors resulting in
1829 error_type). Fix C++ virtual member fn comment.
1830 (read_struct_type): Avoid bumping pointer if we got a parse
1831 error; this prevents our walking beyond the end of a string.
1832 Terminate loop on null char as well as semicolon.
1833 (process_one_symbol): Fix the LBRAC fix so that it uses the
1834 last previous SLINE, FUN, or SO record's PC address. C++ debug
1835 symbols did not have SLINE records in a useful order compared
1836 to the LBRAC records.
1837 (define_symbol): Handle "catch" records.
1839 * symtab.c (check_stub_type): Added new complain
1840 `stub_noname_complain' and added a consistency check to
1841 keep the debugger from crashing when finishing from an
1842 exception frame. A real fix will be needed later.
1844 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1846 * infcmd.c (attach_command): Make global.
1848 * Makefile.dist (REMOTE_OBS): Make these compile by default,
1849 but make them easy to comment out. Perhaps later they should
1850 be enabled by what CPU you configure for? FIXME.
1851 (VERSION): Roll to 3.93.
1852 (pinsn.o): Remove rule for obsolete file.
1853 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
1855 Run down a problem that manifested by printing the wrong function
1856 name in stack traces of read_ofile_symtab. Turned out that the
1857 problem was the SunOS 4.1.1 (and previous) C compiler outputs
1858 the LBRAC symbol with an address in the *data* segment, which
1859 blew our binary search through the blocks.
1861 * dbxread.c: Use the complain() facility consistently to bitch
1862 about problems in the symbol file we are reading.
1863 (finish_block): Add code to check the nesting of the blocks;
1864 complain and Procrust them to fit if wrong.
1865 (make_blockvector): Check the order of the blocks, complain
1866 [but don't cope] if wrong.
1867 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
1868 symbols to be sure their PC value is greater than the last SLINE
1869 (line number) symbol we've seen, complaining and adopting the
1870 SLINE PC value if wrong.
1872 * symfile.h (struct complaint, complaint_root, complain,
1873 clear_complaints): Add.
1874 * symfile.c (complain, complaint_root, clear_complaints): Add
1875 facility to deal with non-fatal complaints and to regularize their
1877 (symbol_file_add): Clear complaint counters to allow new complaints.
1878 (initialize_symfile): Add 'set complaints' and 'show complaints'.
1880 * dbxread.c (dbx_symfile_read): Remember the address and size
1881 of the string table for the main symbol file, so we won't read it
1883 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
1884 to avoid reading the string table yet again. Lint.
1885 (throughout): Improve filtered output, including word wrap.
1886 (read_range_type): Improve Bothner's fix to handle other types too.
1888 * utils.c: Improve line wrap implementation. Handle unlimited
1889 width by making chars_per_line unsigned.
1890 (puts_filtered): New, easy, function.
1892 * defs.h (puts_filtered): add.
1894 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
1895 call the identical sort_symtab_syms() in symfile.c instead.
1897 * expread.y: Suggest the `file' command rather than `symbol-file'.
1899 * command.h (enum var_types): Add zinteger for seroable
1901 * command.c (do_setshow_command): Handle var_zinteger. Restructure
1902 nested if's into a switch.
1904 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
1905 we did not stop because of a breakpoint (it must have been for
1906 some other reason, like a "stepi"), so don't print anything.
1908 * symtab.c: Include <sys/types.h> all the time. Now that BFD
1909 doesn't include <sys/types.h>, old SunOS's require it for
1912 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
1914 A test port of gdb-3.92.6 to the Sony NEWS.
1917 Don't normally link in remote- or vx stuff.
1918 Some of it doesn't compile, and it wastes space for 99% of the users.
1919 Remove reference to no-longer-used HAVE_VPRINTF.
1920 Fixed BFD_DEP typo to BFD_DIR.
1922 Fix cast in arg to bfd_h_getlong.
1923 Make char *prefix be const.
1924 Fix how certain range types are mapped into builtin unsigned int types.
1926 Remove 2 #includes. They cause errors (on Sony, at least),
1927 and aren't needed (they wern't in earlier versions).
1929 print_address_symbolic should never demangle labels
1930 (since it prints *assembler-level* labels).
1932 [This was superseded by the change to printcmd below.]
1935 Add some "volatile" return types to avoid warnings.
1936 If MISSING_VPRINTF add vprintf function and not just macro
1937 (since vprintf is used in printcmd.c).
1939 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
1940 (The latter isn't grokked by some PCC-based compilers.)
1942 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
1944 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
1945 * nindy-share/coffstrip.c
1946 Added some forward declarations (otherwise, gcc complains
1947 about implicit extern redefined as static).
1949 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1951 Changes inspired by Per Bothner:
1952 * printcmd.c (print_address_symbolic): Take additional parameter
1953 specifying whether to demangle.
1954 (print_address): Pass in asm_demangle to control demangling.
1955 (print_address_demangle): New fn, takes explicit arg to control
1957 * utils.c: Add new vars demangle and asm_demangle, and let them
1959 (fputs_demangled): If !demangle, just print the argument.
1960 (fprint_symbol): If !demangle, just print raw symbol.
1961 * valprint.c (val_print): Call print_address_demangle rather than
1962 print_address, to cause demangling to depend on the global
1963 rather than assembler-level demangling setting.
1964 * WHATS.NEW, gdb.texinfo: Document.
1966 * main.c (show_command): Show all settings if no arg.
1967 (initialize_main): Make "info set" the same as naked "show".
1968 * command.c (cmd_show_list): Handle prefix commands in the
1969 list, and print the name of the setting as well as its English
1970 description and value.
1972 Allow gdb functions to specify where a line should wrap if it
1973 exceeds the size of a terminal line. Use it to make the output
1975 * utils.c (set_screen_width_command): New fn, mallocs a buffer
1976 of the right size when screen width changes.
1977 (set_screensize_command, screensize_info): Remove #if 0'd fns.
1978 (wrap_here): New fn, indicates a point in the output where we
1979 should wrap the line rather than just letting it overflow at a
1981 (fputs_filtered): Implement wrapping.
1982 (n_spaces): New fn, returns a pointer to N spaces.
1983 (print_spaces_filtered): Use n_spaces.
1984 * defs.h (n_spaces): Declare.
1985 * stack.c (print_frame_info): Wrap with 4-space indent after
1986 fn name and before filename and line number.
1987 * printcmd.c (print_frame_args): Wrap with 4-space indent
1988 before each argument name is printed.
1989 * valprint.c (value_print): Wrap with no indentation before
1991 (val_print_fields): Wrap with indentation relative to nesting
1992 level before each field name.
1993 (val_print): Wrap with nesting indentation before array elements.
1994 * command.c (do_setshow_command): Avoid extra newlines,
1995 wrap with 4-space indent around values printed, end with period.
1996 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
1998 * breakpoint.c (breakpoint_1): Implement addressprint for
1999 "info breakpoints" display. Change file name and line number
2000 format to " at file:nnn" rather than " (file line nnn)".
2001 * gdb.texinfo: Document.
2004 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2006 Frozen for gdb-3.92.6 release.
2008 README, WHATS.NEW: Update for 3.92.6 release.
2010 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2011 coffread.o from configs since it is now built by default.
2012 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2013 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2014 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2015 from configs since it is now built by default.
2017 Makefile.dist: Update for release 3.92.6. Handle files that
2018 have been moved to ../include, ../getopt, or ../bfd. Add
2019 saber.suppress and tests directory. Add config.status to
2020 the release (it will say "none").
2022 coredep.c: Minor formatting fixes.
2024 These changes were made in early December but only checked in now:
2025 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2026 nindy-share/nindy.c: lint
2027 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2028 register values coming back from the target; we store values
2029 in target byte order everywhere.
2031 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2033 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2035 * valprint.c (cplus_val_print, val_print_fields): New functions,
2036 which print C++ objects. They conspire to avoid printing a
2037 virtual base class more than once, following all the twists and
2038 turns of C++ virtual base rules.
2039 (val_print): Call the above rather than do it by hand.
2041 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2042 symbol file, not for added files like shared libs. This really
2043 needs to be generalized to a timestamp per file.
2045 * core.c (cleanup_core): Avoid coredump if no core file.
2047 * config.gdb: Accept -host or -target in place of +host or
2050 * coffread.c (find_linenos): Avoid desupported BFD interface
2051 to line numbers. We still read them manually rather than using
2052 BFD's "generic" features.
2054 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2056 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2058 * Makefile.dist: Eliminate use of $< in explicit targets.
2060 * readline/Makefile: Use $< rather than $*.c, which does not
2061 include the VPATH in GNU Make.
2063 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2064 copies of tconfig/i960, added for global configuration
2065 compatability. All i960 versions can read both coff and b.out.
2067 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2068 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2071 * TODO: Think of more things to do.
2073 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2075 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2076 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2077 64-bit float conversion.
2079 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2080 equivalent to sun?os4 so global config works.
2082 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2084 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2086 * main.c: Only declare linesize once; declare pagesize not at
2087 all, since it is never used.
2088 (main): Clear newly allocated line before it is used.
2090 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2092 Further stabilization for the Intel 960.
2094 * Makefile.dist: Parameterize the location of the "include"
2095 and "bfd" directories, as well as "getopt". Add symfile.c.
2096 Link in both dbxread and coffread. Fix up "make depend" to
2097 rewack the locations of include, bfd, and getopt in its output.
2099 * README: Document moving include files, improve some of
2102 * coffread.c: Move common code out to symfile.c. Change
2103 symbol_file_command style interface to use new *_symfile_init
2104 and *_symfile_read interface under BFD. Use BFD internal
2105 info to locate line table, symbols, etc.
2107 * core.c (core_fetch_registers): Rename to get_core_registers
2108 to avoid confusion with fetch_core_registers.
2109 (register_addr): Move to coredep.c, which is already machine
2110 dependent. This leaves core.c pretty clean of dependencies.
2112 * coredep.c (register_addr): Accept this routine from core.c.
2114 * dbxread.c: Move common code (with coffread.c, etc) into new
2115 symfile.c. Each psymtab now contains a pointer to the
2116 format-dependent function that knows how to read it in. Make
2118 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2119 (process_one_symbol): Add code to complain about a "compiler bug
2120 we muzzle here", if we actually see it.
2122 * eval.c (evaluate_subexp): Insert missing "break" statements
2123 in code that determines whether a variable is an lvalue in
2124 memory, register, or whatever. I detected this via a compiler
2125 bug in which it *almost* mashed out the whole switch statement.
2127 * gdb-int.texinfo: Add minor sections on configuring gdb for
2128 release, and about the README file.
2130 * infcmd.c (registers_info): Fix formatting somewhat. Still
2131 not as pretty as before, but it handles byte swapping.
2133 * remote-nindy.c: If data cache routines are interrupted while
2134 waiting for the remote end, be sure that any uninitialized cache
2135 blocks are on the free list, not on the valid list!
2137 * symfile.h: Flesh out this header file with all the various
2138 routines and variables that have been merged in from dbxread.c
2139 coffread.c, and symtab.c to symfile.c.
2141 * symfile.c: New file, containing code common to dbxread.c,
2142 coffread.c, and some code from symtab.c. All generic code for
2143 reading symbol files should be in here now.
2144 (unrecord_misc_function): Remove unused function.
2146 * symtab.h: Remove file-reading things to symfile.h.
2148 * symtab.c: Remove file-reading things to symfile.c.
2150 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2151 to decode i960 fault types.
2153 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2154 target.c: Change type of the "resume" function from int to void,
2155 since its result was never used.
2157 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2159 * main.c: Replace "stupid" with "caution"; you now "set caution
2162 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2164 * infcmd.c (do_registers_info): Call val_print to deal with the
2165 byte order of the registers being printed. FIXME, this makes
2166 the formatting of the output uglier.
2168 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2169 defined, call it for signals the debugger doesn't itself use.
2170 The i960 uses this for more detailed fault information.
2172 * remote.c (remote_open): If arg is null, print help rather than
2175 * sparc-xdep.c (register_valid): Avoid declaring size, since
2176 various modules will think of various sizes depending on the
2177 architecture of their tm-file. FIXME, we need protection against
2178 actually entering one of those modules, which would clobber
2179 storage if not for the target architecture compiled into gdb.
2181 * stack.c (up_command, down_command): Always print the frame
2183 (up_silently_command, down_silently_command): New commands
2186 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2188 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2189 more parameters than it used to.
2191 * findvar.c (registers): Increase slop to 256 bytes, which should
2192 protect us against even most RISC machines with large register
2194 (locate_var_value): Move declaration inside related ifdef.
2196 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2197 throughout, to avoid throwing away buffered input from the board.
2198 (nindy_wait): Supply_register takes addr_of_value, not value.
2199 (i960_print_fault): Renamed from i80960_fault.
2200 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2201 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2203 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2204 we can set the PC in the call to proceed(). Unpush nindy_ops
2205 before pushing it on top, to avoid message to user. Eliminate
2206 commentary from Unix machines that just misleads here.
2207 (reset_command): Fix error message to suggest target command.
2209 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2211 Release 3.92.5 as frozen.
2213 Stabilize the merged release...with help from lint, Saber C,
2216 Everywhere: Add include files needed to declare return types
2217 of functions called.
2219 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2221 * breakpoint.h: Add undeclared breakpoint functions, and some
2222 functions for display handling since I couldn't think of a better
2225 * breakpoint.c (insert_breakpoints): Make code for disabling
2226 shared library bkpts more likely to work. It's used when we
2227 rerun a program and stop before the shared library has been
2229 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2230 cast from pointer, so it squeezes through catch_errors.
2231 (bpstat_stop_status): Fix logic broken some time ago. We now
2232 always create a bpstat if the stop address matches a breakpoint,
2233 even if we don't stop there -- just like the old code used to do
2234 before I got my fingers into it (sigh).
2235 (breakpoint_1): Print "ignore count" after "stop only if"
2236 condition, since that's how it actually works.
2237 (mention): Handle watchpoints as well as breakpoints.
2238 (watch_command): use set_raw_breakpoint and mention to do most
2239 of the work (and initialize all the fields!). Only pass one
2240 arg to parse_c_expression, since that's all it takes.
2242 * command.c (not_just_help_class_command): Rename arg to args
2243 since we ignore "unused argument" warnings on vars named "args".
2244 inflow.c (child_terminal_info): ditto.
2245 infptrace.c (kill_inferior): ditto
2246 main.c (catch_errors, version_info, quit_command, pwd_command,
2247 source_command, dump_me_command, editing_info,
2248 set_history_size_command, set_history, show_history,
2250 stack.c (locals_info): ditto
2251 target.c (target_files_info): ditto
2252 valprint.c (set_input_radix, set_output_radix): ditto
2254 * core.c: Remove old variables for handling core and exec file
2255 sections (data_start, data_end, stack_start, stack_end,
2256 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2257 text_end, exec_data_start, exec_data_end, text_offset,
2258 exec_data_offset, data_offset, stack_offset). They're
2259 superseded the more general build_section_table and
2261 (get_exec_file): Mention the `file' command.
2262 (read_memory_check): Rename to memory_error, and only call it
2263 in the case of an actual error.
2264 (read_memory, write_memory): call memory_error.
2265 (core_fetch_registers): Register section name is ".reg".
2267 coredep.c: Remove a bunch of crud now that all this file does
2268 is pull the registers out of a core file.
2269 (fetch_core_registers): Rewrite to actually work, I hope.
2271 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2272 Replace index() with strchr(). Remove all the pre-BFD macro
2273 definitions for accessing the symbol file.
2274 (struct dbx_symfile_info): Encapsulate the information that
2275 dbx_symfile_init needs to pass to dbx_symfile_read in this
2278 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2279 dbx_symfile_discard): Rearrange symbol file reading to divide
2280 the format-specific part from the format-independent part,
2281 leaving the format-independent part such as file name expansion
2282 and opening in symtab.c. This replaces
2283 partial_symbol_file_open and partial_symbol_file_read.
2284 Symbol_file_read, add_file, add_file_target_command,
2285 add_file_addr_command move to symtab.c. Pass an explicit
2286 "mainline" flag for when reading the main symbol table, rather
2287 than relying on the offset address to be zero or nonzero.
2289 (dbx_symfile_read): Don't allow void *'s to be printed as
2291 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2292 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2293 macro" debug version really work.
2294 (read_dbx_symtab): Remove unref'd parameter inclink.
2295 Avoid swapping N_SLINE symbols, for speed.
2296 Merge N_TEXT!N_EXT case with the other external symbol
2297 definitions' case. Add comments.
2298 (start_psymtab): Allocate the symfile name in the psymtab on
2299 the psymbol_obstack, rather than using the caller's storage.
2300 (end_psymtab): Only allocate a dependencies list if there are
2302 (psymtab_to_symtab_2): Use BFD when reopening file to read
2303 its symbols for real.
2304 (read_struct_type): Add FIXME comments where it needs work
2306 (read_huge_number): Add FIXME about overflows.
2307 (read_range_type): Add FIXME about comparing a long to 1<<32.
2309 * coffread.c: Minor changes to move things closer to the new
2310 regime with symtab.c and dbxread.c Major work is still needed
2313 * exec.c (exec_file_command): Remove old variables (see core.c
2315 (xfer_memory): If memory transfer is right at the end of a
2316 section, don't lose.
2318 * findvar.c (get_saved_register): If value is in a real
2319 register, LVAL is lval_register, not lval_memory.
2321 frame.h: Declare print_sel_frame and record_selected_frame.
2323 gdb-int.texinfo: New file, for GDB internals documentation.
2324 Very simple, unformatted doc of cleanups is there for now.
2326 gdbcore.h: Remove obsolete variables that described a.out
2327 section addresses and offsets. (See core.c above.)
2328 Declare fetch_core_registers and registers_fetched.
2330 getopt.c: Declare char *alloca(); even on SPARC.
2332 infcmd.c (run_command): Call target_kill rather than
2334 (step_command, next_command, stepi_command, nexti_command):
2335 Declare from_tty parameter even though we don't use it.
2336 (run_stack_dummy): argument BUFFER is a char array, not
2337 a pointer to REGISTER_TYPE.
2338 (finish_command): using_struct_return needed a value *,
2339 not a struct symbol *.
2341 * infptrace.c (child_xfer_memory): To avoid dependency on
2342 where sections are in memory, try PT_WRITE_D and if that fails,
2343 try PT_WRITE_I. Most Unixes don't care which you use.
2345 * infrun.c (step_resume_break_shadow): Change to array to
2346 match other breakpoint shadow storage.
2347 (clear_proceed_status): Pass address of bpstat to
2348 bpstat_clear, not the bpstat itself.
2349 (child_create_inferior): FIXME comment about if the child
2351 (start_inferior): Remove old function.
2352 (child_open): Use target_kill rather than kill_inferior.
2353 (wait_for_inferior): Ditto.
2354 (insert_step_breakpoint, remote_step_breakpoint): Use
2355 new step_resume_break_shadow.
2357 * inftarg.c (child_wait): If all child processes die,
2358 pretend that the one being waited for exited with signal 42.
2360 * main.c (command_line_input): When scanning for comments,
2361 don't coredump on unclosed quotes.
2362 (quit_command): Use target_kill rther than kill_inferior.
2363 (_initialize_main): Rename class_user from "user" to
2366 * printcmd.c (print_command_1): Initialize "fmt" if no format
2367 is specified by the user.
2368 (print_frame_args): Only add to args_printed if we are
2369 actually fetching args from the stack (avoiding undefined
2371 (_initialize_printcmd): Remove bogus \{ from string.
2373 * remote-eb.c (eb_open): Avoid coredump on no argument.
2375 * remote-nindy.c: Bring out of Intel environment into new
2376 target environment. Remove all conditional compilation on
2377 I80960. Massive hacking throughout.
2378 (nindy_xfer_inferior_memory): New routine stolen from
2380 (nindy_create_inferior): New routine pieced together, probably
2381 not quite working yet.
2382 (nindy_ops): New target_ops struct for nindy.
2384 * remote-vx.c: Use write_memory rather than target_write_memory
2385 to get error checking.
2386 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2388 (vx_create_inferior): Use target_terminal_ours...
2390 * signame.c (_initialize_signame): Always initialize, since
2391 we need the table for things other than psignal.
2393 * solib.c (solib_add): Use symbol_file_add, not add_file.
2394 (solib_address): Return boolean result rather than struct
2395 pointer which nobody else knows the type of.
2397 * sparc-tdep.c, valops.c: Use write_memory rather than
2398 target_write_memory, to get error checking.
2400 * stack.c (locals_info, catch_info, args_info,
2401 get_selected_block, frame_command, up_command): Use
2402 target_has_stack, rather than have_inferior_p or
2405 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2407 * symfile.h: New file, defining the interface between the
2408 generic and object-file-specific symbol reading code.
2410 * symtab.c: Move generic symbol-reading interface to symtab.c,
2411 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2412 table to map BFD targets to symbol-reading modules in GDB.
2413 Change index to strchr.
2414 (lookup_struct_elt_type): Use error() rather than hand-made
2415 simulations thereof.
2416 (lookup_partial_symbol): Speedup slightly when length == 0.
2417 (symbol_file_add): New function.
2418 (symbol_file_command): Call it.
2419 (symfile_open, symfile_init): New function.
2420 (add_file_target_command, add_file_addr_command): moved from
2423 * target.c (target_command): use target_kill.
2425 * target.h (target_files_info): Don't declare, never called
2428 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2429 files to determine stack end address.
2431 * valarith.c (value_x_binop, value_x_unop): Change error message
2432 to be more useful. Pass proper argument to value_struct_elt.
2434 * valops.c (value_assign): FIXME comment that long long
2435 bitfields will break here.
2437 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2438 Update `make saber_gdb' to work better.
2440 * TODO: A woman's work is never done.
2442 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2443 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2444 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2445 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2446 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2447 valops.c, valprint.c, exec.c: Lint.
2450 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2452 Continuing Intel 960 port merge of GDB.
2454 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2455 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2456 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2457 Wack over "make depend" so it handles files in subdirectories
2458 vx-share, nindy-share, bfd, and in the current directory.
2460 * blockframe.c (get_prev_frame_info): Remove fatal error
2461 if stack not defined.
2463 * core.c (core_open, core_detach): New functions that handle
2464 the old "core-file" command as "target core" and "detach" instead.
2465 (core_file_command): Call them.
2466 (core_xfer_memory): Use common routine xfer_memory.
2468 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2469 dbxread now uses bfd for everything but symbol reading itself.
2470 BFD internals are used to drag out the relevant file offsets.
2471 (partial_symbol_file_open): Change args all around for BFD.
2473 * symtab.c: Rename "value" to "val" everywhere, so we can
2475 (symbol_file_command): New command, moved from dbxread.c
2476 and coffread.c. It uses BFD to read the file, then vectors
2477 based on its type, to dbx or coff symbol readers.
2478 * symtab.h: Extern a few vars for symbol_file_command.
2480 * target.h: Breakpoint takes a char * save area, not a char **.
2482 * valprint.c (val_print): When unpacking bitfields, offset
2483 the address in gdb of the value, if it is declared with a shorter
2484 type. Remove the last "runtime kludge test" of host byte order.
2486 * utils.c: Remove old my_bfd_read routine.
2488 * stack.c (frame_info): Use target_has_stack. Print program counter
2489 register's actual name rather than "pc", since it's called the
2490 "ip" (instruction pointer) on the i960 (sigh).
2492 * target.c (target_command): Add command for selecting a target
2493 type and calling its open routine. This is used for initiating
2494 communication with a particular target, in a generic way.
2496 * tm-i960.h: Update for modern gdb. Remove semicolons from
2497 various macros. Handle reading struct return convention, and
2498 error-out attempts to return structs with the "return" command.
2499 Be sure gdb doesn't think we know how to call functions in the
2502 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2503 to i960_xxx in lower case.
2504 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2505 not being defined yet.
2507 * remote.c (remote_open): Call start_remote to initialize
2508 wait_for_inferior during open.
2509 (remote_xfer_inferior_memory): Return length written rather
2512 * remote-vx.c (target_command -> vx_open): Use new generic
2514 * remote-eb.c, inftarg.c, exec.c: ditto.
2516 * infrun.c: Fix comments.
2517 (attach_program -> child_open): Use new generic target command.
2518 (wait_for_inferior): Clear saved register values before target_wait,
2519 so target_wait can set some of them if convenient.
2521 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2522 Return success indicator, not void.
2523 (child_xfer_memory): Avoid fetching initial word if we'll
2524 overwrite it anyway.
2526 * infcmd.c (attach_command): Use new generic target open routine.
2527 (_initialize_infcmd): Update doc on attach and detach commands.
2528 (do_registers_info): Merge in a byte-order problem as a FIXME
2531 * findvar.c (find_saved_register): Avoid problem in current frame.
2532 (read_relative_register): Ditto.
2533 (write_register): Convert byte order on the way out.
2535 * exec.c (file_command): Add.
2536 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
2537 (xfer_memory): Common function between core_xfer_memory and
2539 (exec_xfer_memory): Use it.
2541 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
2543 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
2544 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
2545 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
2547 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
2549 Merge Intel 960 port of gdb, continuing...
2551 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
2552 symbol_file_command): Pass from_tty arg to hush 'em up.
2554 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
2555 Add magic numbers for 960 COFF format.
2557 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
2559 Merge Intel 960 port of gdb, from Intel "1.2" release.

2572 Tue May 29 12:54:49 PDT 1990
2573 Added variable baud rate (-b switch).
2574 Source code reorganization.
2576 Thu Apr 26 11:09:55 PDT 1990
2577 More cleanup of batch mode; specifically, execute "-s", "-e", and
2578 "-se" switches as soon as they are encountered on the invocation line.
2580 Fri Apr 20 13:47:15 PDT 1990
2583 Thu Apr 19 09:54:28 PDT 1990
2584 Add 'reset' command.
2586 Wed Apr 18 09:48:07 PDT 1990
2587 After opening remote tty, wait for 1 second to go by without input
2588 from it before trying to talk to NINDY (fixes problems with the
2589 Heurikon HK80/V960E).
2591 Mon Apr 4 16:33:05 PDT 1990
2592 Some output was not being suppressed in 'batch' mode.
2594 Thu Mar 22 15:31:11 PST 1990
2595 Ask user if old symbol table should be deleted when new file is
2598 Allow user to run a program downloaded before gdb960 was brought up.
2600 Correct "exec-file" help message for i80960 context.
2602 Correct bug in calculating user space address: could occasionally
2603 corrupt user program.
2605 Make sure to zero low-order bits in rip's because of bug in 960CA

2610 code loaded at addresses higher than 0x7fffffff.
2612 Wed Jan 10 12:43:22 PST 1990
2613 Open remote tty for exclusive use.
2615 Fri Jan 5 12:14:42 PST 1990

2619 Mon Oct 23 12:03:04 PDT 1989
2620 Use G960BASE and G960BIN environment variables to find 'sx' utility.
2622 Mon Oct 16 14:15:09 PDT 1989
2623 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
2625 Mon Oct 2 15:56:31 PDT 1989
2627 Added 960CA disassembly support.
2629 To simplify maintenance:
2630 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
2632 - eliminated opcode.h: incorporates tables into i960-pinsn.c
2633 - moved 960-specific routines from i960-pinsn.c to i960-md.c
2634 - made disassembly interface identical to that in gdmp960.
2638 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
2640 * target.h: Allow targets to stack. Add target_has_memory,
2641 _registers, etc. Restructure memory access and "info files"
2642 to walk the target stack.
2643 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
2644 target.c: Change tables to match target.h.
2645 * inflow.c (child_mourn_inferior): pop child_ops.
2646 (generic_mourn_inferior): Use new has_stack flag.
2647 * infptrace.c (child_xfer_memory): New memory regime.
2648 * inftarg.c (child_files_info): New "info files" regime.
2649 * remote-eb.c: New memory regime, new info files.
2650 * remote-vx.c: New memory regime, new info files. Now use
2651 separate targets for VxWorks attachment to machine, and
2652 actually running a process under VxWorks, since one has
2653 stack & execution & regs and the other doesn't.
2654 * remote.c: New memory regime, new info files.
2655 * sparc-xdep.c (fetch_core-registers): New memory regime.
2656 * target.c: New routines and support for stacked targets,
2657 new memory regime, new info files regime.
2660 Generalize section handling for an arbitrary number of sections,
2661 including use of the new BFD (binary file) library.
2662 * gdbcore.h: Add struct section_table.
2663 * exec.c (build_section_table): Iterate all sections and
2664 record what gdb needs to know about them.
2665 (exec_command): Use it.
2666 (exec_xfer_memory): Use the table.
2667 (exec_files_info): Print the table.
2668 * core.c (core_file_command, core_xfer_memory, core_files_info):
2670 * source.c (find_source_lines): Use bfd_get_mtime.
2671 * dbxread.c: Quick changes to make it compile with new BFD.
2672 * utils.c (error): Avoid using bfd_error in generic routines.
2674 * core.c (core_fetch_registers): Get from the ".regs" section of
2676 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
2678 * inferior.h (attach_flag): Export.
2679 * infcmd.c (run_command): use new target_create_inferior.
2680 * infrun.c (child_create_inferior): Don't return result.
2681 * Makefile.dist (VERSION): 3.91.4.
2683 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
2685 * breakpoint.c (bpstat_num): Handle breakpoints which have
2686 since been deleted, such as temporary breakpoints.
2687 infcmd.c (program_info): ditto.
2689 * core.c (core_file_command): Display the frame where the core
2694 * remote-vx.c (target_command): Merge in target command from
2695 targ-vx.c. A few other cleanups.
2697 * TODO, Projects: Lots more stuff to do...
2699 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
2701 Massive changes to wall off the remote-debugging interface
2702 behind a function vector. The port to handle VxWorks targets
2703 is also part of this.
2705 All files: Replace references to renamed functions,
2706 remove references to remote_debugging, remove references to
2707 have_include_file, have_core_file in favor of target_has_stack,
2708 target_has_memory, etc.
2710 * Modularize the breakpoint interface.
2711 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
2712 a breakpoint instruction.
2713 breakpoint.c: struct breakpoint's shadow_contents now sized as
2715 (insert_breakpoints): Vector to target to install breakpoints.
2716 (remove_breakpoints): Vector to target here too.
2717 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
2718 sparc-tdep.c (single_step): Use new breakpoint interface for
2719 the single-step breakpoints.
2720 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
2721 New file, contains routines to insert and remove breakpoints by
2722 reading out the old contents and later replacing them. This is
2723 how ptrace breakpoints work, and many remote systems as well.
2725 * tm-vxworks68.h: New config file, overrides a few things for
2726 Wind River's preferences.
2728 * target.h: New file, for transfer vector used to talk to the
2729 inferior (child, attached, core, exec, remote, etc). All accesses
2730 to the thing being debugged should come through these vectors.
2731 target.c: New file, routines to handle transfer vector.
2732 (various files): Add transfer vectors XXX_ops for the various
2733 targets and pseudo-targets (core files, etc) we support.
2735 * breakpoint.c (bpstat_stop_status): Further explorations of
2736 watchpoints and why things don't work all the time.
2737 (bpstat_alloc): New fn to allocate a bpstat and chain it.
2739 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
2740 the local gdbinit if it doesn't already have it.
2742 * core.c (core_ops): add and install.
2743 Allow core debugging without exec file.
2745 * dbxread.c (free_and_init_header_files): Merge two fns.
2746 (end_symtab): Free named symbol table when a new version comes in.
2747 (read_dbx_symtab): Relocate all kinds of symbols with base
2748 address. First step toward handling different text, data, bss
2750 (add_file_addr_command): Renamed add_file_command.
2751 (add_file_command): Vector to remote handler.
2752 Add "load" as an alias for "add-file" command.
2754 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
2755 non-returning functions.
2757 * exec.c: Add exec_ops, and push it as a target when an exec
2760 * infcmd.c (run_command): Pass executable file name and arg list
2761 separately when starting an inferior. Permit "run" when no exec
2762 file is specified, for VxWorks.
2763 (detach_command): Move to child_detach in inftarg.c.
2765 * inftarg.c: New file. Unix-child-specific routines, and the
2766 child_ops structure.
2768 * inferior.h (registers): Export "registers" as the way for
2769 target dependent register handlers to find gdb's local copy of
2770 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
2771 since it is now used by places that want wait_for_inferior to
2772 handle the grunge but want to see every trap from the inferior.
2774 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
2775 Eliminate remote_debugging hooks in terminal handling.
2777 * infrun.c: Replace start_inferior with child_create_inferior.
2778 Move all the hair of Unix shells and ptrace idiosyncracies into
2779 child_create_inferior, so remote handlers don't have to deal.
2780 Remove running_in_shell. Rename stop_after_attach to
2781 stop_soon_quietly, and use it in a few other places where we want
2782 to just call wait_for_inferior and get control back on the first
2783 trap. trap_expected now never takes a value > 1.
2784 (init_wait_for_inferior): Initialize static vars when a new
2787 main.c (gdbinit): Add new hook for .gdbinit file name, let
2788 it be overridden by config files as GDBINIT_FILENAME.
2789 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
2790 Both of these are used for VxWorks gdb.
2792 mcheck.c: rename include file "gmalloc.c" to avoid problems
2793 with system include file "malloc.c".
2795 param-no-tm.h: New include file, same as param.h but does not
2796 include the default "tm.h" file. This is used in files where
2797 the target is known, e.g. remote-eb.c or sparc-xdep.c.
2799 param.h: Now just a shell that includes tm.h and param-no-tm.h.
2801 remote-vx.c: New file, VxWorks remote debugging support. Uses
2802 RPC routines that are shared with the target system, in directory
2805 remote.c: Vectorize remote interface.
2807 source.c: Globalize source_path, and make an alias "l" for "list"
2808 since we now have the "load" command.
2810 sparc-xdep.c: Use new param-no-tm.h.
2812 symmisc.c (free_named_symtab): Add new function from Wind River.
2813 However, ifdef it out for now while we think about what it should
2816 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
2818 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
2819 non-Unix-children handle this with their own code in the target
2822 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
2823 source and target lists. Add vx-share to default list of include
2824 directories. Add new files to src and target lists: mem-break,
2825 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
2826 ${srcdir} versions of munch and createtags are used.
2828 * valops.c (find_function_addr): Split out of call_function.
2829 (call_function_by_hand): Rename call_function; this function
2830 calls functions in the target by laboriously patching the target
2831 word-by-word with the right stack, args, regs, etc.
2834 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
2836 Handle AMD 29000 a bit better.
2838 * remote-eb.c (readchar): Mask received char log to make it readable.
2839 (remote_start): Pass arguments down to executing program.
2840 Make startaddr unsigned.
2841 infrun.c (start_inferior): Accept args, pass them to
2843 infcmd.c (run_command): Pass args down to start_inferior.
2845 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
2846 the target object file format.
2847 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
2849 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
2850 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
2852 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
2854 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
2855 * TODO: We did a few things, we have more to do though.
2857 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
2858 * inflow.c (inferior_died): Clear deferred stores.
2860 * Debug problems with dummy frames and calls to the inferior.

2862 * sparc-tdep.c (do_restore_insn): Simplify.
2863 (sparc_frame_find_saved_regs): Simplify and fix what we find.
2864 (sparc_push_dummy_frame): Simplify and fix what we push.
2865 (sparc_pop_frame): Slightly more hair here, deciding whether
2866 we are restoring a saved PC or returning to a return address in %i7.
2867 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
2869 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
2870 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
2871 * obstack.h (chunkfun): ditto.
2872 * defs.h (xmalloc, xrealloc): ditto
2874 * utils.c (quit): Grab the terminal from the child if necessary.
2876 * inflow.c (term_status_command): Rename to term_info, change
2879 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
2880 (is_delayed_branch): Speed up.
2881 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
2882 Still missing some float ops, and needs testing.
2884 * Support for input and output radixes other than base 10
2885 * defs.h (input_radix, output_radix): Declare.
2886 * expread.y (yyparse, parse_number): Handle changes of input
2887 radix, and ambiguous names-or-numbers in radixes >10.
2888 * printcmd.c (print_scalar_formatted): Print formatted hex
2889 numbers in varying column widths.
2890 * valprint.c (val_print): Use output_format to print scalar ints.
2891 (set_input_radix, set_output_radix, set_radix): Create.
2892 (set_output_radix): Set output_format from output_radix.
2893 (_initialize_valprint): add `set radix' but leave the others off.
2895 * main.c (execute_command): Let stupid questions be turned off.
2896 (_initialize_main): Handle "set stupidity", etc.
2898 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
2899 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
2901 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
2903 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
2904 bfd stuff is still screwed up, but with some manual work, it
2907 * breakpoint.c (bpstat_do_actions): Start over if a command
2908 proceeds the inferior, since the inferior will have stopped and
2909 will need to have its new stop-actions taken care of.
2911 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
2912 compiler fits, simplify it.
2914 * gdb.texinfo (directory command): Doc new dir command.
2915 source.c (directory_command): "dir" now puts things on the front
2916 of the path, moves dups up front, and handles multiple names
2917 on the command line, inserting each one in order. It also
2918 blows away cached line and full_filename info.
2920 * stack.c (backtrace_command): Skip "more stack frames follow"
2923 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
2924 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
2925 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
2926 The only odd one was Gould NP1, which had defined vprintf to
2929 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
2930 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
2931 variable, inspect_it.
2932 valprint.c (print_string, val_print): Use the global inspect_it
2933 to indicate whether to print in Epoch style or normal style.
2935 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
2937 * printcmd.c (call_command): add an alias for the "print" command
2938 which runs expressions and doesn't print the result if void.
2939 (print_command_1): implement it.
2941 * command.c: Remove #if 0'd code. Initialize all the fields
2942 in add_cmd (). Rename do_nothing_command to
2943 not_just_help_class_command, and make it externally visible.
2944 command.h: add user_commands to struct.
2945 * main.c (define_command): Don't overload c->function with a char
2946 string as well as a function pointer.
2948 * eval.c (evaluate_subexp): Reinstall tiemann changes to
2949 calling convention of value_struct_elt () that got dropped in
2952 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
2953 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
2955 * tm-sparc.h (POP_FRAME): replace some constants with defines.
2957 * sparc-xdep.c (store_inferior_registers): defer stores to regs
2958 until a good time (e.g. when we are about to run the child),
2959 saving ptrace calls.
2960 * infrun.c (proceed): handle DO_DEFERRED_STORES.
2961 * tm-sparc.h: define DO_DEFERRED_STORES.
2963 * sparc-xdep.c (store_inferior_registers): when storing float
2964 registers, don't store stack regs too. When storing the SP,
2965 however, DO store the stack regs too. This fixes a bug in which
2966 the dummy frame is not recognized when a call_function finishes,
2967 because its frame pointer (in the stack regs) was never
2969 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
2970 even though we don't know how to read them from an inferior.
2971 valops.c (call_function): Comment about storing SP.
2973 * infrun.c (save_inferior_status): Save away the original bpstat
2974 chain so it can be restored later. Install the copied version for
2975 use by whoever saved the status. It will be blow away by
2976 restore_inferior_status, and the original chain restored. This is
2977 important for people who have pointers into the original.
2979 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
2980 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
2981 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
2984 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
2986 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
2987 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
2988 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
2990 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
2992 * Merge Mike Tiemann's multiple inheritance changes from Sun.
2993 Store the baseclasses in a type struct starting from array element
2994 0 rather than from the unusual array element 1.
2996 dbxread.c: the above.
2997 (virtual_context): Add
2998 Read new debug information about which virtual function table
2999 a virtual function is from, and store it in fn_field.fcontext.
3001 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3002 TYPE_FN_FIELD_STATIC_P.
3004 symtab.c: the above.
3005 valops.c: the above. Handle pointer casts of object *'s.
3006 (search_struct_method): Add.
3007 (value_struct_elt): First arg is now a pointer to a value, and is
3010 valprint.c: the above.
3011 values.c (value_virtual_fn_field): Add type arg. Handle
3012 offsetting to the proper object when calling virtual fns.
3014 (baseclass_addr): Add valuep arg.
3016 * README: Document the current state of BFD config (missing).
3017 * TODO, ChangeLog, Makefile.dist: Roll version.
3018 * WHATS.NEW: Add summary of changes since 3.5.
3020 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3022 * dbxread.c (read_struct_type): Clear bit vectors whenever
3024 symtab.c (B_CLRALL): define.
3026 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3027 using == rather than =. Huh... This fixes the dreaded problem
3028 wherein builtin_type_int becomes TYPE_CODE_FLT.
3030 * core.c (info_files): Show the inferior pid.
3032 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3033 already knows how to look in the source directory.
3035 * Remove psymtab hair from many places. Remove duplicated code
3036 for searching symbol tables. Hide psymtabs from most places.
3037 Make it fast to get from a psymtab to its symtab.
3039 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3040 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3041 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3042 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3043 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3044 new symtab completely. New psymtabs get symtab pointer
3045 initialized to zero. Remove MI warning printf.
3046 symtab.h: Comments. Add psymtab to symtab pointer.
3047 (PSYMTAB_TO_SYMTAB): New macro.
3048 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3049 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3051 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3053 (print_frame_info): Avoid special-casing symbols that have not yet
3056 * source.c (open_source_file): Quick path if we have already
3057 located the source file by its full name.
3059 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3060 find_pc_psymtab. When a name is found in the misc function
3061 vector, search the symbol table for its mangled name, not the
3062 name that the user typed.
3064 * bfd.h: Fix missing comment terminators, make #endifs match.
3066 * valarith.c (value_less): Handle unsigned int comparisons.
3067 Add FIXME about pointer compares, which assume host and target
3068 pointers are the same.
3070 * command.c (do_nothing_command): lint
3071 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3072 fix comments on debug symbol format for visibility. Actually set
3073 visibility of symbols.
3074 main.c (echo_command): lint; use <readline/history.h>.
3075 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3076 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3077 pointing past end of allocated memory; saber complains.
3078 obstack.h: Declare the external functions that we use.
3079 valarith.h: use <string.h>
3080 solib.c (solib_add): lint.
3082 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3084 * main.c (initialize_main): Default info_verbose to off, now that
3085 symbol reading is fast.
3086 (quit_command): Avoid clobbering exec_bfd while quitting.
3088 * Initial BFD (binary file diddling library) merger:
3089 coffread.c: Change AOUTHDR to struct exe_hdr.
3091 core.c: initialize initialized data at compile time.
3092 (core_file_command): Move from coredep.c, convert to bfd.
3093 (xfer_core_file): Convert to bfd.
3094 exec.c (exec_file_command): use bfd routines.
3096 mips-tdep.c: Remove exec_file_command and friends.
3099 * coredep.c: (fetch_core_registers) Convert core_file_command to
3100 fetch_core_registers.
3101 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3103 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3104 (my_bfd_read): More bogosity, which I don't think we call.
3105 (program_name): Remove this atrocity asap!
3107 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3110 values.c: allocate_repeat_value was not clearing the
3111 optimized_out field.
3112 (value_static_field): minor stylistic fix (wrong macro was used).
3113 valops.c (value_struct_elt_for_address): didn't work for C++
3116 * signame.c (_initialize_signame): Initialize signal names once.
3118 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3119 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3120 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3122 * remote-eb.c: Support user-settable baud rates on the serial port.
3124 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3126 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3128 * tconfig/sun3os4: Remove warning about native assembler,
3129 since it also occurs in the xconfig file.
3131 * findvar.c (registers): Allocate some slop after `registers'
3132 to prevent stray accesses from trashing the next variable.
3134 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3135 on the sun-3, by changing the #ifdef from `sun3' (which is not
3136 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3137 vars, which happened to follow `registers' in the executable.
3139 * readline/history.c (history_search): Heed gcc-2's advice
3140 and parenthesize && inside ||).
3142 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3143 tm-29k.c: Insert FSF copyright headers.
3145 * remote-eb.c: Better comments.
3147 * Makefile.dist: Update to 3.91.6.
3148 * TODO: note PREPARE_TO_STORE problem.
3150 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3152 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3154 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3156 * infrun.c (wait_for_inferior, at end): Don't set up
3157 prev_* if the inferior no longer exists.
3159 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3160 CANNOT_EXECUTE_STACK.
3161 valops.c (call_function): Use it.
3163 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3165 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3166 infrun.c (wait_for_inferior, 2 places): Use it.
3168 * values.c (value_being_returned): Only use
3169 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3171 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3172 right thing for remote-eb.c.
3174 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3175 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3177 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3178 (FRAME_FIND_SAVED_REGS).
3180 * findvar.c ({fetch,store}_registers): Check for
3181 REMOTE_{FETCH_STORE}_REGISTER macro.
3183 * findvar.c (get_saved_register): Add argument lval and
3184 change meaning of argument addr.
3185 findvar.c: Change calls to get_saved_register to reflect
3186 new calling convention.
3187 valops.c (value_assign): Use get_saved_register instead of
3188 find_saved_register.
3190 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3192 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3193 an (uninitialized) pointer to one. Use "&" when passing it
3196 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3198 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3201 * coffread.c (symbol_file_command): Put semicolon after
3203 Put safe_to_init_tdesc_context in #if defined (TDESC).
3204 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3205 coffread.c: #include <sys/stat.h>.
3206 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3207 Add missing ')' in check for "lc%" and friends. Remove
3209 Declare read_one_sym() at top of file.
3210 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3211 MC68WRMAGIC can have the same value without causing a duplicate
3214 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3216 * Allow a Makefile to be built without building the
3217 tm and xm file links that screw up builds in subdirectories.
3218 This is done with `config.gdb none', then you can do things
3219 like `make gdb.tar.Z'.
3220 * tconfig/none: Config file for no target system
3221 * xconfig/none: Config file for no host system
3222 * config.gdb: If no TM or XM files are called out by the
3223 host or target file, don't make links for them.
3225 * cplus-dem.c: Add documentation.
3227 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3228 simple error, so the user's gdb doesn't crash due to some object
3229 file problem (e.g. somebody is rebuilding the file out from under
3232 * printcmd.c (print_address_symbolic): demangle the symbol.
3234 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3235 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3236 (alldeps.mak): sort and uniq all results from this; duplicates
3237 hose gdb.tar.Z link building. Remove RCS files from
3238 tconfig and xconfig. Add config files for sun386. Add
3239 a few odd files to OTHERS and HFILES.
3241 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3243 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3244 Roll version number to 3.91.5. Make lint work in bindir.
3246 * README: Document cross-debugging and new file structure.
3248 * blockframe.c: Lint. Include "value.h" to declare read_register.
3249 (find_pc_partial_function): remove duplicate line.
3251 * command.h: Lint. Declare error_no_arg and dont_repeat.
3253 * tm-news.h: Remove inadvertently duplicated stuff.
3255 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3256 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3258 * config.gdb: Allow `config.gdb host target' form. Clean
3259 up previous change that printed bogus messages when you just said
3262 * core.c: #include "command.h" for lint.
3265 * main.c: Remove some casts of enums. Lint.
3272 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3274 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3275 read it from memory. This will allow us to save ptrace calls
3276 eventually. Changed caller single_step too.
3278 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3279 that we aren't going to use, saving many ptrace calls, especially
3280 when watchpointing or single stepping. Use some #define's for
3282 (store_inferior_registers): Ditto.
3283 (core_file_command): Use some #define's for constants.
3285 * tm-sparc.h: Add #define's for some register numbers, so we
3286 can eliminate the use of random constants in sparc-xdep.c.
3288 * stack.c (frame_command, print_frame_info, up_command,
3289 down_command) Remove frame_changed, since it
3290 causes a bug and doesn't seem to do anything useful. In some
3291 places it was used as a flag, in others as a stack level (?).
3293 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3294 default is to use the portable (vprintf) version rather than the
3296 * xm-news.h (MISSING_VPRINTF): Add.
3298 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3300 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3302 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3303 about linking debugged programs -Bstatic in the sun?os4 config
3304 files in tconfig and xconfig subdirectories.
3306 * main.c (main): Remove unreached exit(0) now that we exit
3309 * Create TODO file for online bug list. There are too many
3310 "little" bugs to keep track of on paper.
3312 * Change Projects file to refer to bug-gdb@cygnus.com
3313 rather than kingdon@ai.
3315 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3317 * Makefile.dist (VERSION): 3.91.4 now.
3319 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3320 (condense_misc_bunches): Add sanity check that misc_count is
3321 the same as the number of symbols in the bunch.
3323 * coffread.c: rename init_misc_bunches. Pass an argument
3324 to condense_misc_bunches (a zero).
3326 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3327 every time we are called; don't rely on our caller to do it.
3328 (add_file): Remove call to init_misc_bunches.
3330 * mipsread.c: Only warn, don't error, if unknown symbol types.
3331 This keeps an old gdb from falling on its face if it sees newly
3332 extended symbol info. Rename init_misc_bunches.
3334 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3336 * Merge in changes from Per Bothner for DECstations and other
3337 MIPS stuff. The rest is Bothner speaking:
3339 The next message is a merger of Alessando Forin's mips port with
3340 mine. I've tried to use my good if biased judgment to get
3341 the best of both. It *does* need testing.
3343 Some of the changes are general, *not* mips-specific.
3346 Didn't believe in little-endian bit order.
3347 There are still inconsistencies about whether flags
3348 like BITS_BIG_ENDIAN are integer (#if ...) or
3349 boolean (#ifdef ...). I tried to paper over them.
3351 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3352 Moved some misc_function code that was common to
3353 {dbx,coff,mips}read.c to symtab.c.
3354 In the process, I think I cleaned things up a bit.
3355 At the same time, moved obsavestring and obconcat to symtab.c.
3358 Removed obsolete condense_addl_misc_bunches (use
3359 condense_misc_bunches(1) instead).
3362 Needed to include <sys/dir>, at least on DECstations.
3364 valops.c, mips-tdep.c, tm-mips.h:
3365 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3366 conventions (when STACK_ALIGN is insufficient).
3367 Needed on mips, where doubles need 8-byte alignment,
3368 but ints only need 4.
3371 Removed cruft that was not being used.
3372 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3375 Print $ before register-names (I think that makes things a little
3377 Never print two instructions, even if one delays.
3378 Removed hex-disassemble set_cmd. (This is not mips-specific,
3379 so I think the argument is whether it is generally worthwhile or not.
3380 I'm inclined to think not, given how easy it is to
3381 convert between radixes in gdb.)
3384 This is basically Alessando's code.
3385 It doesn't use obstacks; I changed it to use obstacks
3386 in a few minor places where using malloc causes a
3387 memory leak. (Probably, more places could/should be changed.)
3388 I added record_misc_function where it was missing.
3389 In symbol_file_command and add_file_command, I tried
3390 to make the code consistent with more recent versions.
3391 Minor sylistic changes in parse_procedure.
3392 Make a .gdbinfo. psuedo-symbol point back to the real
3393 procedure symbol (using the isym field).
3396 This is basically from my port, but with a lot of details
3397 and a number of routines merged in from Alessando's version.
3398 I basically used my code "raw" backtrace (use heuristics
3399 from the actual code, rather than symbol table info) - though
3400 the idea is Alessandro's. I feel my code is a little cleaner
3401 here, particularly in being a little more flexible, such as being
3402 able to handle gcc-produced code (which it now can).
3403 It also doesn't do frame caching (which is not useful
3404 more recent gdb versions).
3405 I also used my code for push_/pop_dummy, more or less.
3406 I tried to incorporate AF's code for testing sigtramp
3407 while backtracing; I probably got it wrong.
3408 Added mips_print_register, which tries to scrunch as much
3409 information as possible on a screen...
3410 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3411 under mips-pinsn.c), I don't see anything mips-specific here,
3412 and I don't see it being all that useful anyway.
3415 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3416 Use more register names (rather than hard-cases numbers).
3418 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3420 * Hack up 3.90.11 changes:
3422 * Makefile.dist (depend): parameterize $(GCC).
3423 Add solib.c and solib.o.
3424 (readline): Fix vpath for both absolute or relative SRCDIR.
3426 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3427 Also, let the part I didn't understand at least compile so
3428 I can test the rest. FIXME.
3430 * dbxread.c: Fix thinko using strcmp.
3431 (init_psymbol_list): declare static.
3432 (partial_symbol_file_open): Comment cleanups better, avoid
3433 cleaning up the string table since the caller will do that.
3434 Move the stat for mod time into symbol_file_command, temporarily.
3435 (There should be a mod time for each symbol file, eventually,
3436 to control its rereading. FIXME.)
3438 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3439 SunOS, which gives error for shared libs otherwise. (From
3440 Schaefer, probably FIXME needs work for portability.)
3442 * solib.c: Move #include "param.h" to work.
3443 Lowercase all the Uppercase Letters In the Messages.
3444 (find_solib): Clean up inferior_so_name for debug printouts.
3445 Allow no argument, to mean all shared libraries.
3447 * symmisc.c: include param.h to get CLEAR_SOLIB.
3449 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3451 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
3452 to 3.90.11. ChangeLog entries below are from this.
3454 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)

3460 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3464 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
3466 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
3468 * sparc-opcode.h Added single-operand version of rett.
3470 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3472 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
3473 Put parens around gcc_p in expansion.
3475 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3477 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
3479 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3481 * Changes for Sun shared libraries:
3482 blockframe.c (find_pc_partial_function): If a non-text symbol
3483 is found, set *address = pc - FUNCTION_START_OFFSET.
3484 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
3485 Disable breakpoints instead of giving an error.
3486 source.c (select_source_symtab): Initialize cs_pst.
3487 symmisc.c: Call CLEAR_SOLIB if defined.
3488 symtab.h: Make text{low,high} CORE_ADDR not int.
3489 (psymtab): New field addr.
3491 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
3492 (record_misc_function): Give correct type for N_DATA symbols.
3493 (condense_misc_bunches): do "misc_function_count = j" regardless
3495 Take code which is shared between symbol_file_command and
3496 add_file_command and put it into partial_symbol_file_{open,read}.
3497 Split add_file_command into add_file_command and add_file.
3498 Make psymtab_to_symtab read in the string table if the file
3500 Two new parameters to read_dbx_symtab and start_psymtab.
3501 tm-sunos.h: New file.
3503 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3505 * infcmd.c: Change cont_command to continue_command and "cont"
3508 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3510 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
3512 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
3514 * values.c (USE_STRUCT_CONVENTION): Check for structures of
3515 size 1,2,4,8 rather than size < 8.
3517 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
3518 as necessary, not just once.
3520 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3522 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3524 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3526 * tm-news.h: Add CALL_DUMMY_*.
3528 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
3530 * config.gdb: In list_host, list_target, use ${i}, not $i.
3532 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3534 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
3536 * sparc-opcode.h: Change all store floating-point state register
3537 instructions to have the right match & lose fields.
3539 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3541 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
3543 config.gdb: If srcdir != ., create readline directory and
3544 copy a makefile into it.
3546 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
3547 consistency with POSIX.
3549 * breakpoint.c (bpstat_stop_status): Disable watchpoint
3550 when we exit its exp_valid_block.
3552 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
3554 * Makefile.dist: Bump version to 3.91.3.
3556 * Clean up handling of breakpoint commands (somewhat).
3557 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3559 inferior.h: Add breakpoint_proceeded to inferior status struct
3560 and globals; save it and restore it.
3561 (clear_breakpoint_commands): Cleanup, remove old #define.
3563 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3564 (save_inferior_status, restore_inferior_status): handle it also.
3565 (proceed): Remove earlier code that set breakpoint_proceeded.
3566 It is now set only in clear_proceed_status.
3567 (clear_proceed_status): Cleanup, use bpstat_clear rather
3568 than clear_breakpoint_commands. No callers need the stop_bpstat
3569 between clear_proceed_status and proceed.
3571 infcmd.c: Add breakpoint_proceeded definition and comment.
3572 (cont_command, jump_command, signal_command): Move call to
3573 clear_proceed_status right next to call to proceed.
3575 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3576 caller's argument while running down the chain of breakpoints.
3577 Use new variable "breakpoint_proceeded" to determine when
3578 a command that it executes moves the inferior past the
3580 (bpstat_clear): Handle NULL argument.
3581 (bpstat_clear_actions): Avoid useless call to
3582 breakpoint_auto_delete.
3583 (delete_breakpoint): Clean up bpstat's that are pointing to
3584 the deleted breakpoint from the stop_bpstat chain.
3585 (breakpoint_auto_delete): Simplify.
3587 * Clean up handling of EOF, error on stdin, etc. This was
3588 prompted by a network problem that caused gdb to go into an
3589 infinite loop filling up its malloc'd memory.
3591 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
3592 not clear_breakpoints_commands, which is now gone.
3593 (main): If command_loop returns (e.g. from EOF on stdin), do
3594 a quit_command (looping back to command_loop if quit_command
3595 doesn't really quit).
3596 (command_loop): check result from command_line_input and
3597 exit if it returns NULL, rather than passing the NULL to
3599 (gdb_readline): Free malloc'd result space before returning
3602 * utils.c (query): Handle C-d to mean "yes", just as if the
3603 input was not a terminal. Also avoid infinite loop if EOF
3604 occurs in mid-input-line before newline. This allows
3605 query to be used at EOF on stdin with reasonable results.
3607 * infrun.c (proceed): Set breakpoint_proceeded.
3609 * values.c (value_as_long): Avoid infinite recursion for enums.
3610 (_initialize_values): Fix typo in help msg (kingdon).
3612 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
3613 RL_LIB for linking. This allows -lreadline for linking
3614 and nothing for dependencies, once readline is a real library.
3616 * config.gdb: Jim Kingdon: give useful error message if the
3617 host or target type is not recognized.
3619 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
3620 it just defines it. Dumb, but deal with it.
3622 * Jim Kingdon suggests:
3623 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
3625 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
3627 * Makefile.dist (VERSION): Bump version # to 3.91.2.
3629 * Clean up Bothner's changes.
3631 * blockframe.c (clear_pc_function_cache): New function.
3632 * blockframe.c: remake cache_pc_function_* static.
3633 * dbxread.c (symbol_file_command): remove references to
3634 cache_pc_function_* variables.
3635 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
3636 * printcmd.c: Avoid kludging a global variable (addressprint)
3637 to avoid printing the address of a string twice. Instead,
3638 pass the format letter 's' down low enough that it can be seen
3639 to avoid this problem.
3640 (print_formatted): Pass format arg to value_print.
3641 (restore_addressprint): Remove function.
3642 (do_examine): Avoid hacking addressprint, cleanups and such.
3643 (print_frame_args): Add a comment to a Bothner change.
3644 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
3645 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
3646 to wipe out the values cached in blockframe.c.
3647 * symtab.c (find_method): Add comment saying how big you must
3648 allocate to be "big enough". Per being terse again.
3649 * valprint.c (val_print): Handle format letter "s" to print
3650 strings without addresses. Add comment to vtbl printing code
3651 which casts with wild abandon. Rearrange reference-printing
3653 @0xaddr: value (print w/addressprint)
3654 value (print w/~addressprint)
3655 @0xaddr (parameter lists w/addressprint)
3656 or nothing (parameter lists w/o addressprint)
3658 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
3660 * Merge more changes from Per Bothner:
3662 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
3663 annoying) that I tried to improve it. Here are my suggestions.
3665 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
3668 Do automatic de-reference when taking the address of a reference.
3670 Don't deref_ref when printing parameter lists.
3672 More attempts at treating refernences properly.
3674 In val_print, if deref_ref==0, don't print dangling " = ".
3676 Add COERCE_REF macro, which de-references an REF.
3678 * Merge changes from Per Bothner:
3680 * Fixed (Sony news)-specific configuration problems.
3681 * Fixed other problems with using vanilla pcc and libc (enum problems;
3682 assumption that vsprintf exists).
3683 * Some major speed-ups (finc_pc_partial_function now caches a match;
3684 parsing avoids duplicate symbol_lookup calls).
3685 * Changed handling of baseclasses (no longer use baseclasses field
3686 of struct type, use the first n_baseclasses fields instead).
3687 * Various minor changes/fixes, most C++-related.
3690 Cache the most previous match from find_pc_partial_function.
3691 (Save both low and high ends of matching function's pc range.)
3692 This speeds up the loop of infrun.c:wait_for_inferior quite
3693 a bit, and makes step/next commands much zippier.
3695 Added an enum->int cast (otherwise, some compilers barf).
3697 No longer set baseclass offset to 0, since multiple
3698 inheritance now mostly works.
3699 Added a number of casts, to shut up compiler warnings
3700 (after stabs where made enums, not ints).
3701 When discarding a symbol table (in symbol_file_command),
3702 must clear the cache introduced in blockframe.c.
3703 Don't convert $vtbl_ptr_type to vtbl any more.
3704 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
3705 Mask off sign bit emitted by g++ for virtual table offset.
3706 Set voffset to -1 (not 1) for static member functions.
3708 Changed parsing/lexing of names to avoid doing symbol lookup twice
3709 (once when lexing to determine symbol class, once for real).
3710 Now only call symbol_lookup once. Fields of 'this' win especially big.
3712 Subpress printing addr twice in the case of 'x/s addr'.
3714 lookup_basetype_type is no longer used.
3715 Add find_methods as recursive helper function to decode_line_1.
3716 This allows multiple inheritance to work.
3717 Also, once one or more matches has been found, do not look in
3718 base-classes. (Baseclass methods would be overridden, anyway.)
3720 Removed baseclasses array in struct type.
3721 Instead of using baseclasses[i], use fields[i-1].
3722 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
3723 Changed sign convention of voffset (previous was inconsistent).
3725 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
3727 Used to assume existence of vsprintf. Re-written to not need it
3728 if HAVE_VPRINTF is undefined.
3730 typecmp was too pessimistic. Made it less so.
3732 Don't print space after address.
3733 If vtable points to a misc symbol (with 0 offset), print it,
3734 since that indicates the actual class of the object.
3735 Changed ype_print_derivation_info to use new inheritance
3736 scheme (without baseclasses vector).
3738 In value_primitive_field, fixed some bugs left over from previous set of fixes.
3739 Also, changes needed because TYPE_BASECLASSES were removed.
3741 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
3743 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
3746 If there is no path set, and the symbols don't indicate what directory
3747 a file was compiled in, look in the current directory. But either
3748 a path or a known compilation directory will prevent this.
3751 Three independent bug fixes:
3752 * Remove the #if 0 block that breaks some stuff.
3753 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
3754 adapt gdb to either SunOS 4.0.* or 4.1.
3755 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
3758 Instantiate the class T when looking for methods in it. (Tiemann@sun)
3761 (type_print) Demangle the name being printed.
3762 (type_print_base) Handle botched demangling without coredump (tiemann).
3765 (check_stub_method): Document routine.
3766 (tiemann) fix bug for no-arg functions
3767 Avoid clobbering beyond end of malloc'd storage.
3768 Terminate the argument list properly.
3770 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
3772 * Changes merged by John Gilmore:
3775 In breakpoint_1, use new print_address_symbolic instead
3776 of find_pc_partial_function. (This forces use of assembler-level
3777 addresses, and avoids misleading non-mangled source-level names.)
3779 Generalize ansi argument such that -1 means skip arglist totally.
3780 Removed global variable print_ansi_qualifiers (which made
3781 code non-reentrant), in favor of extra explicit arguments
3782 to internal routines.
3784 Add new helper function print_address_symbolic.
3785 Use find_pc_misc_function instead of find_pc_partial_function
3786 (since we want assembler-level symbols here).
3788 Print unknown function as just "f (...)", not "f (...) (...)".
3789 Use new fputs_demangled explicitly.
3791 Fixed a typing violation (problem: value.h cannot be imported
3792 without renaming many variable in this file).
3793 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
3794 decode_line_1: Moved forward some never-reached code.
3795 Made decode_line_2 skip function prologues correctly.
3797 fputs_filtered should not demangle by default.
3798 Add new fputs_demangled to demangle on demand..
3800 Change value_struct_elt to use value_primitive_field (using recursive
3801 utility function search_struct_field). This allows foo.bar to work
3802 for multiple inheritance (so far only for data fields).
3803 Change check_field in the same way (recursive helper function
3804 to support multiple inheritance).
3805 (Note: there are more of these problems that I haven't fixed.
3806 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
3807 value_of_this: 'this' symbol name is now just "this", note "$this".
3809 Don't print static members.
3810 Avoid printing "members of <type>" if there are none.
3811 Simplified type_print_derivation_info by merging duplicate code.
3812 Remove useless blank lines in type_print_base (ptype command).
3814 Added declaration of new routine value_primitive_field.
3816 Added value_primitive_field which is generalized version of
3817 value_field that can handle multiple inheritance (non-zero offsets etc).
3818 Re-implemented value_field to call value_primitive_field.
3820 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
3822 * infcmd.c -- insert else to avoid 'delete env' coredump when you
3823 delete the whole environment. Karl Berry reported the bug.
3824 * source.c - fix openp to avoid //'s in filenames, which
3825 trigger an Emacs bug causing it to not be able to find files
3826 when running gdb in a window.
3827 * dbxread.c - zap the #if 0 that botches the add-file code.
3828 It seems to work a lot better without all the code commented out.
3830 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
3832 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
3835 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
3837 * Makefile - added a ${CFLAGS} to a couple of entries,
3838 added remote-sa.sparc.c
3839 * added remote.sa-sparc.c, a modification of remote.c
3840 which conducts a dialog directly with the SparcStation prom.
3841 * breakpoint.c, infrun.c, sparcdep.c added
3842 remote_insert_breakpoint(), and remote_remove_breakpoint()
3843 to breakpoint.c instead of directly writing breakpoint instructions.
3844 * sparcdep.c on remote_debugging,there is no need
3845 to remove signle step breakpoint instructions.
3846 * main.c added "-epoch" flag and "int epoch_interface" to main.c
3848 * printcmd.c - epoch interface sends lisp expressions to open up
3849 epoch windows on inspection.
3850 * valprint.c - added arrayprint, and addressprint and made adding
3851 format controls easier
3852 * wait.h added a couple of undef's because we were getting
3853 complaints about WSTOPSIG and WTERMSIG begin redefined.
3856 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
3858 * symtab.c (decode_line_1): Add support for handling method stubs
3859 in the type information.
3861 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
3863 * values.c (baseclass_addr): Run loop from INDEX+1 to
3864 N_BASECLASSES; otherwise, we can still get into a loop.
3865 @@ This should be restructured to use a cleaner search strategy.
3867 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
3869 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
3870 abbreviation "Tt" for tags which have the same name as their
3873 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
3875 * symtab.c (list_symbols): add ability to set breakpoints on all
3876 the functions which match a particular regular expression.
3878 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
3880 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
3881 should print ANSI qualifiers (such as `const' and `volatile').
3882 All callers changed to call with ANSI == 1, except from
3883 `check_method_stub', which uses old-style syntax.
3885 * symseg.h (struct fn_field): Remove unneccessary `args' field.
3886 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
3888 * values.c (check_stub_method): New function.
3890 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
3892 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
3893 * valprint (type_print_base): Ditto.
3895 * symtab.c (gdb_mangle_typename): New function.
3897 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
3899 * breakpoint.c (catch_command): New function. Provides a
3900 mechanism to set breakpoints based on catch clauses.
3901 (disable_catch): Similar, but disables breakpoints on catch
3903 (delete_catch): Similar, but deleted breakpoints on catch clauses.
3905 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
3907 * blockframe.c (blockvector_for_pc): New function.
3908 * blockframe.c (block_for_pc): Changed to call
3909 `blockvector_for_pc' and get the block itself.
3911 * stack.c (catch_info): New function. Prints info about
3912 exceptions which can be caught in the current frame.
3913 * stack.c (print_frame_label_vars): New function. Similar to
3914 `print_frame_local_vars'.
3915 * stack.c (print_block_frame_labels): Prints out labels that are
3916 defined in this frame. These labels are exceptions that can be
3919 * dbxread.c: Updated to handle N_CATCH symtab types.
3921 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
3923 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
3924 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
3925 when printing the type.
3927 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
3929 * valprint.c (val_print): Use `baseclass_addr' to access the
3930 baseclasses pointed to via the derived class object at VALADDR.
3932 * values.c (baseclass_addr): New function. Casts derived pointers
3933 to baseclass pointers taking virtual baseclasses and multiple
3934 inheritance into account.
3936 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3940 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3942 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
3943 exp_valid_block field correctly.
3945 * infrun.c (wait_for_inferior): When checking "don't even think
3946 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
3947 also check step_resume_breakpoint.
3948 Insert breakpoints and continue (not step) if
3949 step_resume_break_address != NULL, even if another_trap.
3950 If trap_expected and we enter sigtramp, then set up a
3952 If trap_expected is set when we hit the step_resume_break,
3954 When calling resume and trap_expected says tell resume to step
3955 (2 places), also check step_resume_break_address.
3957 * infrun.c (wait_for_inferior): Don't set
3958 prev_{pc,sp,func_{start,name}} before calling wait ().
3959 Do set them after exiting loop.
3960 Move their declarations outside functions.
3961 (start_inferior): Initialize them.
3963 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3965 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
3966 Restore old code which distinguishes between trap_expected and
3967 running_in_shell, just make the latter take any non-TRAP signal,
3970 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
3972 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
3973 xconfig/3b1 (CC,PINSN_CC): Define.
3975 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.

3980 infrun.c (wait_for_inferior) [SHIFT_INST_REGS]: New code.
3982 * param.h, tm-88k.h: Define ADDR_BITS_*.
3983 infcmd.c (jump_command, read_pc), infrun.c (wait_for_inferior),
3984 printcmd.c (do_one_display): Use them.
3986 * utils.c: Split #ifdef USG into a USG_UTILS and a QUEUE_MISSING.
3987 xm-88k.h: Define USG_UTILS.
3989 Wed May 2 00:05:33 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3991 * printcmd.c (printf_command) [__INT_VARARGS_H]: New code.
3992 (printf_command): Add from_tty parameter.
3994 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
3996 * value.h: Add optimized_out field and change lazy field to
3997 char. Add macro VALUE_OPTIMIZED_OUT.
3999 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
4000 instead of stuffing things in buffers (oappend, etc).
4002 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
4003 execute_command, exit both loops.
4005 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
4007 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4009 * Makefile.dist (RAPP_OBS, rapp),
4010 rgdb.c, rserial.c, rudp.c, serial.c, udp.c, xdep.h,
4012 m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
4014 * valops.c (value_struct_elt), values.c (value_static_field):
4015 Change error messages to remove references to `info methods'.
4017 Tue Apr 24 10:25:10 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4020 infrun.c (start_inferior): Add START_INFERIOR_HOOK.
4021 infcmd.c [SHIFT_INST_REGS]: New code.
4022 findvar.c (read_relative_register_raw_bytes): Return a value.
4023 infcmd.c (do_registers_info): Check value from
4024 read_relative_register_raw_bytes.
