3 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
4 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
6 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
7 * expread.y, findvar.c, symmisc.c: Ditto.
8 * printcmd.c (address_info): Update printed forms of LOC_
9 symbols. Elim LOC_EXTERNAL.
10 (print_frame_args): Keep track of param stack offsets before
11 re-looking up to find the local register param is kept in.
13 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
14 Further integration of mipsread into gdb. Eliminate unused
15 routines, duplicate declarations. Handle static symbols in
16 psymtabs as well as external symbols. When reading symtabs,
17 insert symbols into the correct block (global, static, or a local
19 (read_mips_symtab, parse_partial_symbols): Don't pass useless
21 (mipscoff_symfile_read): Don't call select_source_symtab.
22 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
23 rather than SYMBOL_VALUE.
24 (parse_external): Comment clobbering of top_stack.
25 (parse_partial_symbols): Update comments. Allocate and parse
26 static symbols as well as external symbols. FIXME, enum values
27 are not handled in this pass, but should be. Inline new_psymbol.
28 Use SYMBOL_VALUE_ADDRESS.
29 (psymtab_to_symtab_1): Read symbols into global static block
30 by default (until enter some function's local block context).
31 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
32 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
34 * source.c (select_source_symtab): Select a source symtab
35 from either the symtabs or, failing that, the psymtabs.
36 (list_command): Update error message.
37 (forward_search_command, reverse_search_command): Use getc, not
38 fgetc, for speed. FIXME, add comment about buffers that die if
41 * values.c (unpack_field_as_long, modify_field): Avoid shifting
42 by an entire word, which is not portable, if we have a 32-bit
43 field. (Code in dbxread.c already turns such bitfields, if
44 aligned, into ordinary ints, but fixing this will help for other
45 symbol formats and for future changes.)
46 * core.c (core_open): Handle ANSI const brain death.
47 * utils.c (vprintf): Fix varargs typo.
49 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
51 * findvar.c (find_var_value): Handle &function better.
52 * TODO: Document work needed on &fn and &array.
53 * printcmd.c (print_address_symbolic): New arg is the prefix
54 to print if a name is printed.
55 (print_address_demangle): Honor "set print address" now.
56 Use new arg above to improve spacing of output.
57 * valprint.c (val_print): When printing function pointers,
58 print symbolic form too.
59 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
61 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
63 * core.c (memory_error): Reword error msg to mislead less.
65 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
67 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
68 parse_partial_symbols): Use newer BFD internals (external_filehdr
69 and external_aouthdr), byte-swap the fields that we care about
70 before using them, and make the file header data local to
71 read_the_mips_symtab rather than global.
73 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
75 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
76 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
78 * main.c (command_line_input): Flush stdout and stderr
79 before every call to readline. This reportedly fixes a bug
80 that comes up in Sys V running emacs-gdb and/or xxgdb,
81 when stdin/out are pipes or sockets.
83 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
85 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
86 Avoid declaring Makefile dependencies, because GNU Make stupidly
87 tries to update it if we do.
89 * coffread.c: Revise for minor changes to bfd internal coff
92 * configure: If -template= is given a relative path, make it
93 absolute before recurring in subdirectories.
95 * configure, configure.in, Makefile.in: Install "configure" script
96 as replacement for config.gdb.
97 * config.gdb, Makefile.dist, Makefile.sdir: Remove
98 * README: Update for configure, mostly. FIXME.
100 * Add dec3100 as equivalent to littlemips. Indicate in all host &
101 target config files that they are for the host. When the lines
102 get copied into the Makefile, this makes it more obvious what's
105 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
107 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
108 tabs, which end up in the disassembler output inadvertently.
110 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
112 Make it compile cleanly in an ANSI GCC2 environment.
114 * blockframe.c: <stdio.h>
115 * cplus-dem.c: free takes a void *, ifdef __STDC__
116 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
118 * defs.h (alloca): Avoid doing anything if alloca already def'd.
119 * stddef.h, stdlib.h: Remove these files.
120 * symtab.c: Avoid declaring qsort, close.
121 * symfile.c: Avoid declaring close.
122 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
123 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
125 Assorted other changes.
126 * dbxread.c: include "libaout.h", not "liba.out.h".
127 * printcmd.c (print_frame_args): Set recurse properly for
128 indentation of struct and array parameters.
129 * valops.c (value_cast): Allow cast to void.
130 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
131 single_step() in a target-independent fashion.
132 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
133 set up to be ready to continue. This makes us target independent.
134 * infptrace.c (child_resume): Remove call to single_step; now
135 can single step a SPARC target of any kind.
137 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
139 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
140 docn into separate sections---basically chapters, plus two loose
141 pieces that can be configured to go in different places. This
142 allows GNU m4 to preprocess the manual without coredumping.
144 * Makefile.dist: tell TeX where to find texinfo.
146 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
148 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
149 the new target "rdl-apps.texinfo" which captures the Makefile
150 variable that records where to find the Readline libraries.
152 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
154 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
155 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
156 * defs.h (const, volatile): Only define if not already defined.
157 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
159 * README: Update for release 3.95.
160 * config.gdb: Don't create readline dir in subdir builds.
161 * main.c: Include with "..." form for non-system include files,
162 so "gcc -MM" for "make depend" works.
163 Include readline files with "...h" rather than <readline/...h>.
164 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
166 * coffread.c: Undo minor damage done by Rich Pixley. Use
167 different internal and external representations of COFF
168 data structures. Use new BFD routines for swapping them in and
170 * symfile.c (free_named_symtabs): Avoid freeing file names that
171 are null or empty. Old i960 tools seem to produce files that
172 claim to have empty names, causing each successive file read
173 to blow away the previous one.
174 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
175 Move deferred_stores to top of file, but don't separate its
176 #define's from its variable. Add commentary.
177 * Makefile.dist: Fix Rich damage; undo "configure" changes in
178 favor of keeping the (working) config.gdb. Move readline
181 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
183 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
185 * infptrace.c (fetch_registers): no result, since now void.
186 * tconfig/news: target depends on m68k-tdep too.
188 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
190 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
193 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
194 applied various small fixes due to or inspired by RMS comments
196 * doc/gdb.texinfo: finished using all RMS comments, save those for
197 appendices on readline and cmd history (which are in other source
200 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
202 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
203 chapter 9; (2) documented 'break' command's menu mode for
204 overloaded names, in response to hgs problem report C++ p-31
206 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
208 * doc/gdb.texinfo: (1) better introductory example; (2) more
209 consistent use of @code, @samp, @file, @kbd throughout; small
210 cleanups to first three nodes; (3) new "Contributors" node;
211 (4) Appendix, Renamed Commands; (5) divert specialized startup
212 instructions to "Targets" chapter for generic manuals, while
213 leaving them up front for manuals specific to specialized
214 environments; (6) apply fixes from RMS comments through chapter 4.
216 * pretex.m4: modify explanatory text slightly (and redefine
217 "regexp") to keep GNU m4 from complaining. (It still crashes
218 later, but one step at a time...)
220 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
222 * readline/readline.c (update_line): Avoid dereferencing a pointer
223 before comparing it to its bounds. Saber caught this.
224 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
225 and only set PC if tgetstr returned non-null. Saber caught this.
227 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
229 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
230 stuff for config manual) here where it counts; updated
231 to use new subdir structure (gdb/doc/).
233 * Makefile: generated from above via
237 * gdbint.texinfo: added instructions on generating gdb.info* files
238 locally for release. These are ordinary info
239 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
240 Makefile)---but due to use of texinfo 2, can't count on makeinfo
241 to generate these, so we distribute them already formatted.
243 * gdb.texinfo: included full Info node and menu crud (as generated
244 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
246 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
247 put in comments-for-future gdb.info target (one day makeinfo will
250 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
252 * gdb.texinfo: Updated to include new or old undocumented
253 commands, at least the following (perhaps some others I forgot to
254 record): info f, info float, info path, info program, info s, info
255 set, info source, info terminal, info types, info user, set/show
257 Also covered all recent GDB command renames for v4.
259 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
261 * mipsread.c: Rather than keeping count of how many symtabs
262 and psymtabs we have, for sorting purposes, count them when
263 we need to sort. This fixes bug in rereading of symbol tables.
265 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
267 * infcmd.c: renamed "info path" to "show paths"

279 * saber.suppress: Update.
281 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
282 symtab.h, target.c, target.h: Lint.
283 * core.c: setup and select frame after reading shared libs,
284 else reading shared libs will clobber them. Lint.
285 * utils.c (error): Force out any buffered wrap text.
287 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
289 * remote.c: Remove decls of memory_insert_breakpoint
290 and memory_remove_breakpoint, no longer used. (Suggestion of
293 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
294 to make it easier to interface to "configure"'d libraries.
296 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
298 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
299 aliases for set/show print.

408 can have both ints and enum type_pieces in it.
409 ({push,pop}_type_int): New functions.
411 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

434 (FRAME_CHAIN): Call sparc_frame_chain.
435 sparc-tdep.c (sparc_frame_chain): New function.
436 tm-sparc.h (EXTRACT_STRUCT_VALUE_ADDRESS): call

439 * xm-sun386.h: Don't define SET_STACK_LIMIT_HUGE.
441 Tue Apr 30 13:13:33 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
443 * valprint.c (type_print_base): If the type being printed is a

472 Sun Apr 28 22:04:47 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
474 * param-no-tm.h: Make BITS_BIG_ENDIAN defined to 0/1, not defined

850 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
851 to the main file, as well as to include files. Also, put global

859 queued to the psymtab list.

904 (set_section_command): New command ("section xxx yyy" -- should
905 be renamed to "set section xxx yyy" FIXME) which sets the
906 base address of a section of the exec file, overriding the
907 virtual address that BFD reports.
909 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
911 * exec.c: Add add_syms_addr_command to exec_ops, so you can

914 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
916 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
917 for printing the float info is host-dependent, not
918 target-dependent. FIXME.
919 * i386-pinsn.c: Move #includes to top, remove useless ones.
920 * i386-tdep.c: Don't bother including <.../reg.h> since we
921 don't use it (and it doesn't exist on host systems).

924 Convert negative numbers properly.
925 (ieee_test): Make numbers really random; fix format arg.
927 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
928 * core.c (core_detach): Unpush core_ops, which might not be on

932 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
933 * expprint.c (print_subexp): Avoid switch fallthru on

937 current frame in the core file, if we have one.
938 (generic_mourn_inferior): When inferior dies, either select
939 the current frame (in the new target, e.g. core file), or
940 set both the current and selected frames to NULL.
942 Changes from Peter Schauer.
944 * infptrace.c: Avoid <sys/ptrace.h> on USG.
946 * Make all file names fit in 14 characters (sigh and damn!):

963 the user-defined commands.
965 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
967 * dbxread.c (really_free_pendings): Clear file_symbols
968 and global_symbols after freeing them; otherwise, running
969 this function twice (if it appears twice on the cleanup
970 chain), we try to free things twice.
972 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
973 based on text_addr (the address of text in core), not on addr (the
974 offset between text in the .o file and in core). This change
975 is from Peter Schauer.
977 * main.c: Define ALL_CLEANUPS as a cast of zero.
978 (return_to_top_level): Use it.
979 (main): Do all cleanups after each command run as part
980 of the gdb startup sequence. Also do all cleanups before
981 entering the command loop, and every time we exit the command
982 loop and reenter. Before, the cleanups from the startup sequence
983 were being left undone until the first error!
984 (command_loop): Rename do_nothing cleanup to command_loop_marker
985 so we can see it easily when examining the cleanup chain.
986 (init_signals): Add another do_nothing for signal handling.
987 (quit_command): Only try to kill target if it has execution.
988 Problems in the target stack got us into a state where
989 inferior_pid was nonzero but none of the targets had execution.
990 In this state you couldn't exit gdb.
992 * dbxread.c: Two changes from Peter Schauer.
993 (echo_command): Fflush output after an echo command.
994 (show_history): Pass all args to cmd_show_list.
996 * utils.c (init_malloc): Call mtrace to turn on tracing
997 if the environment variable MALLOC_TRACE is set to a file name.
998 * mtrace.c: Add source file which provides a log of every malloc,
999 free, and realloc to a trace file.
1000 * mtrace.awk: Add source file which analyzes the trace file.
1001 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1002 (VERSION): Roll to 3.94.3.
1004 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1005 (check_duplicates): Don't bother with watchpoints.
1006 (set_raw_breakpoint): Comment about danger of this routine.
1007 (watch_command): Parse and eval all args before calling
1010 * solib.c (find_solib): Avoid error in referencing memory to
1011 see if any more shared libraries have been added. This is
1012 particularly useful if the target has terminated. Bug reported
1015 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1016 in bringing up 3.94.2 on the Sun-3.
1018 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1019 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1020 expression (in scope) before reenabling watchpoint.
1021 * signame.c (init_sigs): Add missing declaration of i, fix
1022 sys_siglist declaration.
1023 * source.c (list_command): Fixed range computation to use
1025 * stack.c (backtrace_command): Do not allow command if target has
1026 no stack, print informative error message.
1027 * target.c (target_command): Do not write into command line
1028 because this fails if the target command is used in a user defined
1029 command. [This change was enhanced by gnu to support any-
1030 unique-prefix matching on target names.]
1031 * valops.c (value_struct_elt): Avoid infinite loop on an
1032 erroneous attempt to print the member of function (try p main.p).
1034 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1036 * expread.y (name_no_typename): Avoid reduce/reduce errors
1037 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1038 Since the GDB parser really doesn't use name_no_typename in a
1039 name-only context, the parser can't tell the diff between
1040 names and numbers here. Avoid allowing a name_no_typename
1041 to be a NAME_OR_*INT to resolve the conflict.
1043 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1045 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1047 * valprint.c (val_print_fields): bitfield printing didn't handle
1048 byte order. Indirect through a few more fns to cope.
1050 * values.c (modify_field): also cope with byte order.
1052 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1054 Cleanup for release 3.94.2:
1056 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1057 include files. Roll version to 3.94.2.
1059 * coffread.c (init_stringtab): Read length into unsigned char
1060 array before swapping; don't assume 32-bit longs.
1062 * target.c (target_info): Don't bother with get_sym_file, just use
1063 the symfile global variable.
1064 * symtab.h, symfile.c (get_sym_file): Delete it.
1066 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1067 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1068 (read_type): Replace one more error() with complain().
1070 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1072 * i960-tdep.c: Fix copyright attribution.
1074 * config.gdb: Quote all backquotes in doublequotes. You can
1075 quote me on that. BSD 4.4 shell found this one.
1077 * infptrace.c (throughout): The third argument to ptrace is an
1080 * infrun.c (wait_for_inferior): When program has terminated, we
1081 have to call target_terminal_ours before we pop that target off
1082 the stack (e.g. before a call to target_kill or
1083 target_mourn_inferior). This fixes problem where a program
1084 terminates, then GDB stops for (tty output) and you have to type
1085 "fg" to the shell to resume it. FIXME: This code for what to
1086 do after termination really should be in normal_stop instead.
1088 * gdbcore.h (read_memory_check): Change declaration; it changed
1091 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1092 4.4 prereleases, this avoids a bug in their sgtty compatability
1094 * remote.c: Use terminal.h rather than hand-rolling the same.
1096 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1097 * utils.c (strsave, strstr): Fix arg types.
1098 * valprint.c (val_print): lint
1100 MIPS symbol table support from Per Bothner:
1102 * symfile.c (symtab_fns): Remove initializer table that needs to
1103 be hacked for each new symbol file format supported.
1104 (add_symtab_fns): New function, chains symbol table
1105 handlers into the global list.
1106 (symfile_init): Search this list.
1107 * symfile.h: Add next pointer, declare add_symtab_fns.
1108 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1109 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1111 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1112 symbol *). Thus, we no longer need the hack to trash
1113 pst->filename. Good, since that hack confused code in symfile.c!
1115 (reorder_symtabs, destroy_all_symtabs): Removed static
1116 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1117 Instead, the latter now uses a temporary array (stack-allocated
1118 from an obstack, and then freed).
1120 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1121 haven't been set in the outermost stBlock of a procedure. This was
1122 a problem with f77 binaries on Ultrix 4.?.
1124 (new_symtab, new_symbol, new_type): Continue changing code to use
1125 obstacks more and otherwise conform to dbxread internal style.
1126 Made the free_code of symtabs be free_linetable (as in dbxread)
1127 instead of free_contents. This implies memory leaks when reading
1128 a new symbol table, until the conversion is finished. Did change
1129 (struct symbol) and (struct type) to be allocated on the
1130 symbol_obstack. Blocks and blockvectors are among the things
1133 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1134 tested much, but it solved one problem (reported by Meissner), and
1135 cleans up some other things. The problem happened when an
1136 included file contains actual code (functions) and not just
1137 definitions. The mips coff is a little inconvenient there, since
1138 it may cause a procedure to be mapped to the wrong psymtab.
1140 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1141 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1142 this will need work for the new core paradigm.
1144 Opcode patches from the net:
1146 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1147 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1148 missing altogether - they are added here. From Bruce Bauman.
1149 * mips-opcode.h: The low mask for C0 instructions was too small.
1150 From Garrett Lau. I modified the fix to check the entire 32-bit
1153 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1156 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1158 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1160 * dbxread.c (read_type): Pointer subtraction (value_sub in
1161 valarith.c) sometimes failed because the types of the
1162 pointers being subtracted were not identical.
1163 These differed because dbxread.c was allocating pointer types
1164 using dbx_alloc_type+smash_to_pointer_type instead of
1165 lookup_pointer_type. I failed to find a justification for the
1166 former, so I changed it to use the latter. Similarly, I
1167 replaced smash_to_function_type by lookup_function_type,
1168 and smash_to_reference_type by lookup_reference_type.
1170 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1171 _initialize_mipsread): corresponding changes.
1173 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1175 * source.c (mod_path): Do tilde_expand on each component of the path,
1176 rather than on the (list of) paths as a whole.
1177 (print_source_lines): Set first_line_listed in addition to
1178 current_source_symtab and current_source_line. If the source was
1179 not findable, after a "dir" command to fix the problem,
1180 a "list" would get the wrong lines.
1182 While I was there... (gnu):
1184 * dbxread.c (read_type): Change error to complaint.
1186 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1188 First attempt at detailed understanding of symbol table memory alloc.
1190 * dbxread.c (dbx_symfile_read): Free our string table if we
1191 aren't the mainline. Free the "info" struct since we're done with
1193 (init_psymbol_list): Free any previously allocated psymbol lists.
1194 (): FIXME: Should realloc-down the psymbol lists when done reading
1195 the main symbol file?
1197 * symmisc.c (free_symtab): Free fullname field too.
1199 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1200 (REGISTER_ADDR): Make result type unsigned int.
1202 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1203 define REGEX must also define REGEX1 (its dependency).
1205 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1207 * tconfig/i960: No longer works, points you at vxworks960 or
1210 * xgdb.c, XGDB-README: Remove file. Users can get the much
1212 * Makefile.dist: Remove all trace of xgdb.
1214 * breakpoint.c (breakpoint_1): Pass demangle arg to
1215 print_address_symbolic.
1216 (clear_breakpoints): Remove unused function.
1217 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1218 (breakpoint_re_set): Use catch_errors to do them all anyway.
1220 * gdb-int.texinfo (Host versus Target): Add section on what is
1221 a "host" feature versus what is a "target" feature.
1223 * infcmd.c (path_command, path_info): Handle the PATH variable
1224 (object search path) as conveniently as the source search path.
1225 * environ.c (set_in_environ): Set some vars in GDB's environment,
1226 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1227 * source.c (mod_path): New function, from guts of
1228 directory_command, modifies a path. Used by path_command.
1229 (directory_command): Call it.
1230 * defs.h (strsave): Declare.
1232 * utils.c (sevenbit_strings): Add new printing option.
1233 (printchar): Use it.
1234 (strsave): Provide this handy helper routine.
1235 (set_width_command): Rename set_screen_width_command.
1236 (_initialize_utils): "set screen-width" => "set width";
1237 "set screen-height" => "set height"; add sevenbit-strings.
1239 * infcmd.c (do_registers_info): Print floating point registers
1240 in raw hex as well as float format, regardless of whether it is
1241 a "virtual" convertible register.
1242 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1243 regs as a double, just in case it's being used that way.
1244 * values.c (unpack_long): Comment on array/function coercion.
1245 (unpack_double): Argument is in target byte order now. For
1246 integer arguments, just call unpack_long and float the result.
1247 * m68k-tdep.c: include defs.h for "const" handling.
1248 * remote-nindy.c: Use ieee-float stuff.
1249 (nindy_fetch_registers): Unpack double regs to host double, then
1251 (nindy_store_registers): Pack extendeds to host double, flip
1252 around by misusing unpack_double, send as target double.
1254 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1255 zero, as when stopped at the first instruction of a process.
1257 * blockframe.c: Fix filename in comment (param.h => tm.h).
1258 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1259 * tm-68k.h: Fix typos.
1261 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1263 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1265 * coredep.c (fetch_core_registers): Pass end-address of register
1266 section to register_addr as expected. Don't call supply_register
1267 if we'd just pass it garbage.
1269 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1271 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1273 * target.c (push_target, target_info): Cast enums to int for < or
1276 * stack.c (print_frame_info): Identify source file & line
1277 even if we can't print it.
1279 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1281 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1283 Clean up IEEE floating point support.
1285 * ieee-float.h: New file.
1286 * ieee-float.c: Write real routines to convert between host
1287 doubles and various target IEEE extendeds.
1288 * m68k-xdep.c: Eliminate assembler code for extended floats.
1289 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1290 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1291 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1292 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1293 double_to_ieee_extended.
1294 * i960-tdep.c: Define ext_format_i960.
1295 * m68k-tdep.c: Define ext_format_68881.
1296 * sparc-tdep.c: Define ext_format_sparc, though unused.
1297 * Makefile.dist (HFILES): Add ieee-float.h.
1298 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1301 Obsolete the "coffstrip" program in favor of using BFD's strip.
1303 * nindy-share/coffstrip.c: Remove file.
1304 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1305 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1306 * tconfig/nindy960: Remove reference to coffstrip.o.
1308 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1310 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1312 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1313 * dbxread.c: Remove static symfile_bfd.
1314 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1316 * inftarg.c (child_detach): Pop the child_ops vector if the
1317 detach is successful.
1318 * remote-nindy.c (nindy_create_inferior): Don't push a new
1319 nindy_ops since nindy uses the same one for execution and memory
1321 * core.c (core_ops): Use child_attach and child_create_inferior
1322 rather than default attach and create_inferior functions.
1324 Handle floating point registers in core files.
1326 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1327 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1328 This version untested since BFD doesn't yet support sun3 core
1330 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1331 conventions. Fix comments and style. This version has not
1332 been compiled yet, since we have no HP inhouse.
1333 * core.c (get_core_registers): Look for two sections, ".reg"
1334 and ".reg2", and pass both to fetch_core_registers sequentially.
1336 Revise directory path yet again.
1338 * source.c (forget_cached_source_info): Not static any more.
1339 (init_source_path): New default source path is "$cdir:$cwd".
1340 (dir_command): Handle variable arguments ($cdir, $cwd).
1341 (source_info): Print "Compilation directory" rather than
1342 "Originally compiled in" to remind people of $cdir.
1343 (openp): If the path contains $cwd, use current directory.
1344 (open_source_file): If compilation directory is known, replace
1345 first $cdir in path with the compilation directory.
1346 (print_source_lines): Even if we can't print the lines, set the
1347 current symtab and line for future commands like "info source" or
1348 "breakpoint". Also, error message now contains the file name,
1349 line number, and file access error message.
1350 (_initialize_source): Fix help text to describe changes.
1351 * main.c (cd_command): Forget cached source info when we chdir.
1352 * utils.c (strstr): Add simple implementation.
1354 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1356 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1357 Byte-swap COFF symbol tables if necessary when reading them in.
1358 Use complain() to replace error message in one spot. Needs
1359 corresponding change in bfd/coff-code.h to make some symbol
1360 swapping routines non-static.
1362 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1364 Merge changes from Eirik Fuller, for UTek.
1366 * defs.h (errno): Add declaration.
1367 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
1368 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1369 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1370 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
1371 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
1372 declarations of errno.
1374 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1376 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1377 <rpc/rpc.h> and <rpc/types.h>.
1379 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1381 * i960-tdep.c (examine_prologue): Add new argument limit,
1382 which stops the scan at the end of the prologue, or at the PC.
1383 This fixes a problem where it walks down into the code for the
1384 user's statements if that code looks like function prologues.
1385 Mark Fox and I have been bouncing this code back and forth, making
1386 small changes to it. Callers changed to match.
1388 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1390 Cleanup for gdb-3.94 release final:
1392 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1393 the .c files from vx-share and nindy-share, from the various
1394 macros, since they are not found via ALLDEPFILES.
1395 (SFILES): Add tm-i960.h.
1396 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1397 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1399 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1400 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
1402 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
1404 * am29k-tdep.c: Add contribution line.
1405 (examine_prologue): Cache information about function prologues in
1406 the misc-function-vector to avoid lots of references over the
1407 serial line while examining instructions.
1409 * core.c (core_close): New function made from cleanup_core.
1411 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1412 remote-vx.c, remote.c, target.c, target.h,
1413 Update target_ops vector to add attach, close, and load entries.
1414 Use add_syms_addr_command, not add_file_addr_command, for
1415 add_file. Break out close routine from existing code.
1417 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1418 they are in an obstack.
1419 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1421 (define_symbol): Add symbol type parameter; change callers;
1422 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1423 it to influence the symbol class on the i960.
1424 (define_symbol): Swap LOC_CONST's into target byte order.
1426 * exec.c (exec_close): New function.
1427 (exec_file_command): Call it.
1429 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1430 Fix byte order of frame pointer.
1431 (read_var_value): Result of 0 if var's value can't be found,
1432 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1433 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1434 (locate_var_value): Use read_var_value and use its lazy address
1435 as the location of the var's value. Lint.
1437 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1440 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1441 obsolete Intel versions in favor of vxgdb versions.
1442 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1443 code dealing with byte order of values, which Intel did in host byte
1444 order rather than gdb-4's target byte order.
1445 (i960_frame_chain_valid): Move to nindy-tdep.c.
1446 (examine_prologue, skip_prologue, frame_find_saved_regs,
1447 frame_args_address, leafproc_return, saved_pc_after_call,
1448 pop_frame): Add vxgdb versions from Mark Fox.
1449 (examine_prologue, frame_struct_result_address): Add code
1450 to deal with the saved value of G13 (struct return address
1452 (frame_args_address): Modify Mark's version to prefer the
1453 saved value over the current value in the topmost frame.
1454 Cache result in the frame info to avoid performance hair in
1456 (print_fault): Add gdb960 code for printing faults.
1457 (_initialize_i960): Actually call check_host.
1459 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1460 add stub routines. FIXME, these currently just return zero!
1462 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1463 (attach_command): Call target_attach, not target_open, now.
1465 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1466 (child_attach): Rename from child_open.
1467 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1468 don't confuse it with a zero step_resume_break_address.
1470 * inftarg.c (child_detach): Eliminate inferior_pid test.
1471 (child_files_info): Clean up message a bit.
1472 (child_ops): Use child_attach, not child_open, to attach.
1474 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1475 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1476 findvar.c to here, since it depends on the contents of the
1477 shadow_contents of breakpoints, but keep if #if 0 since it is
1480 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1483 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1484 (ptype_command, display_command): Eliminate have_inferior_p and
1485 have_core_file_p in favor of target_has_stack or
1486 target_has_execution.
1487 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1488 code for actually finding the values of arguments, though we still
1489 keep track of the maximum stack offset for use in printing unnamed
1490 arguments. Handle missing FRAME_ARGS_ADDRESS.
1492 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1493 (struct nindy_regs): Define registers passed to/from nindy.
1494 (nindy_fetch_registers, nindy_store-registers): Translate between
1495 nindy and GDB formats for the registers.
1496 (dcache_init): Statically allocate the cache, since it was being
1497 allocated by a malloc that was never freed anyway.
1498 (nindy_create_inferior): Error, not core dump, if no exec file.
1499 (nindy_before_main_loop): Use target_load, not target_add_file.
1501 * remote-vx.c (net_load): Specify large timeout for load
1502 requests. Allow user to break out with INTERRUPT.
1503 (net_break): Remove useless code, clean up. Change callers.
1504 (parse-args, skip_white_space, find_white_space): Clean up arg
1505 parsing to cope with quoted strings.
1506 (net_wait, net_quit): Never call error, just return status.
1507 (vx_read_register, vx_write_register): Cleanup status checking.
1508 #ifdef the code based on which CPU we are using (960 or 68k),
1509 FIXME, this should be completely general but it isn't yet.
1510 (vx_xfer_memory, vx_resume): Cleanup status checking.
1511 (vx_run_files_info): Improve message.
1512 (vx_load_command): Renamed from vx_add_file_command. Allow load
1514 (net_ptrace): Remove unused routine.
1515 (vx_wait): Adopt code from vxgdb960 to cope with broken
1516 connections to target machine and prompt to disconnect. Remove
1517 debug printouts. Map some EVENT_'s to SIGnals.
1518 (add_symbol_stub, vx_open): Print names of object files we found,
1519 and "ok" if we read their symbols OK. Clarify output in general.
1520 (vx_attach, vx_detach, vx_kill): Add these commands.
1521 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1522 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1523 "info files" output, and create_inferior, since we already have
1526 * stack.c (frame_info): Replace Frame_unknown with 0.
1527 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1528 (return_command): Pop until the PC matches as well as the FP,
1529 so it works even if the FP is shared with another function,
1530 as in "frameless" or "leaf" procedures.
1532 * symfile.c (load_command): renamed from add_file_target_command.
1533 (add_syms_addr_command): renamed from add_file_addr_command.
1534 (add_syms_command): Stub to call target_add_syms.
1535 (_initialize_symfile): Change command names and descriptions,
1536 add-file => add-syms, and load from alias to its own command.
1538 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1539 maybe_kill_then_create_inferior): Default for attempts to start
1540 a process, if one is already running, is to ask about killing
1541 it and retry if yes.
1542 (upstack_create_inferior): #if-0 it, strata obsolete it.
1543 (push_target, unpush_target, pop_target): to_close() a target
1544 before unstacking it.
1545 (target_info): Renamed from target_files_info.
1546 (_initialize_targets): Rename "i files" as "i target", accessible
1549 * target.h: Improve comments about the target_ vectored routines.
1551 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
1552 Convert commenting style to standard GNU style.
1553 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
1554 (SKIP_PROLOGUE): No longer a no-op.
1555 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1556 (*_REGNUM): Sort register numbers.
1557 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1558 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1559 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1560 are now 10 byte extendeds, not 8 byte doubles.
1561 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1562 for nindy versus vxworks targets. FIXME, this should possibly go
1563 in the target vector.
1564 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1565 frame_saved_regs and arg pointer with each frame.
1566 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1567 (FRAME_ARGS_ADDRESS): Use cached result.
1568 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1569 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1570 (PRINT_RAMDON_SIGNAL): Call print_fault.
1571 (POP_FRAME): Now works.
1573 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1574 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1575 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1576 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1579 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1580 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1582 * valarith.c (value_subscripted_rvalue): Avoid handling
1583 floats and doubles specially; it gave alignment errors. Lint.
1585 * valops.c (value_of_variable, value_of_this): Error if unknown
1588 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1589 to avoid alignment problems.
1590 (value_print): Handle unknown value address.
1591 (cplus_val_print): Two args are ignored; remove them. Change caller.
1592 (val_print): Use unpack_long rather than pointer-deref.
1595 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1596 to avoid alignment problems.
1597 (value_being_returned): Error if return value unknown.
1598 (set_return_value): Add bogosity warning, FIXME. *
1600 * TODO: A woman's work is never done.
1602 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1603 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1604 Add ieee-float.o to OBS.
1605 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1606 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1607 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1609 Changes to generalize the VxWorks RPC protocol slightly, to handle
1610 i960 as well as 68000.
1612 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1613 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1614 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1615 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1616 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1617 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1618 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1619 so they will move in target byte order rather than network
1620 byte order (happens to be the same).
1622 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1624 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1626 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1629 Add contribution lines to various files, showing where they
1632 * breakpoint.c (break_insn, check_break_insn_size,
1633 read_memory_nobpt): Remove to mem-break.c.
1635 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1638 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1639 entry has bad register number. This change is not
1640 tested in this release, FIXME.
1642 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1645 * value.h: Force value's contents field to be aligned to hold
1646 at least a double or a long long (if supported). This avoids
1647 doing bcopy's in and out of the contents field.
1649 (step_1): Avoid coredump under obscure circumstances when we
1652 * symtab.h (misc_info): Add field to misc function vector for
1653 any kind of cached information the target code desires. AMD
1654 29000 uses this to avoid repeating examine_function_prologue's.
1656 * coffread.c: Lint. Remove static symfile, read_section_header.
1657 core.c (have_core_file_p): Lint: remove.
1658 expprint.c (print_subexp): Lint.
1659 infptrace.c, valops.c, valprint.c: lint.
1661 Roll in changes from vxgdb-5.0.1:
1663 * symtab.h: Comment byte order of each address class. Add
1664 LOC_LOCAL_ARG for frame-relative args (960).
1665 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1666 symtab.c, symmisc.c: ditto.
1668 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1670 * remote.c (remote_resume): Error if resume with a signal.
1672 * symfile.c (prim_record_misc_function): Clear misc_info.
1673 (fill_in_vptr_fieldno): Check stub type of arg.
1675 * valops.c (value_cast): Avoid looking up names of types whose
1676 name we don't know, to prevent coredump. Sun CC produces typedef
1677 rtx and the name of *rtx is zero...
1679 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1681 Roll in changes from final AMD 29000 port (Tiemann).
1683 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
1684 for ../include/a.out.encap.h. This might not work now that BFD
1685 is separately compiled. Instead, BFD support for encap will have
1686 to translate machine type 29k into the right COFF_MAGIC.
1688 * infcmd.c: Remove references to inferior_pid that aren't used
1689 in actual ptrace calls; use target_has_execution, etc.
1690 (have_inferior_p): Remove function.
1691 (program_info): Print target info rather than "process number";
1692 avoid gratuitous messages unless from_tty.
1693 (run_stack_dummy, finish_command): Set proceed_to_finish.
1694 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
1695 main.c: Lint. Lose have_inferior_p().
1696 inferior.h (have_inferior_p): Remove, lint.
1697 (proceed_to_finish): Add flag to ask that all regs be saved
1698 by normal_stop, for the few commands that need it, speeding up
1699 serial I/O. Add comments to stop_registers.
1701 * remote-eb.c: Remove newline from breakpoint message we grep
1702 for. Never time out when running the user program.
1706 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1708 Roll in changes from vxgdb-5.0.1:
1710 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
1711 symbol in its raw form, we are processing an unlinked ".o" file.
1712 See if the target environment has assigned it an address, using
1713 target_lookup_symbol (VxWorks does), and enter it into the symtab
1716 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
1717 68k versions for a simpler version that assumes zero FP at bottom.
1718 Fixes bug of truncated stack reports.
1720 * target.h (target_lookup_symbol): Define this routine's args
1721 and result, finally.
1723 * target.c (nosymbol): Default routine for target_lookup_symbol.
1724 (target_default): Default lookup_symbol and call_function too.
1725 (files_info): Only print has_all_memory warning if a non-dummy
1728 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
1729 vx_convert_from_virtual): If target does not have floating point,
1730 zero register "values", and avoid doing cross-net conversions.
1731 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
1732 (vx_open): Rearrange code that attaches to target and reads
1733 symbols for all loaded modules, to work if some of the modules
1734 are not accessible. Add symbol_stub() and add_symbol_stub()
1735 as callbacks from catch_errors(). Allow connect attempt to be
1736 interrupted painlessly with ^C (FIXME, there are still some bugs
1737 if the interrupt happens during symbol reading.). Print
1738 final message with puts_filtered, since symbol messages are
1743 * main.c (catch_errors): Only print errstring if non-null.
1744 (command_loop): Avoid an ioctl per command to test ISATTY.
1746 * remote-vx.c (net_load): make static; avoid sophomoric msg.
1747 (vx_xfer_memory): Return correct result!
1748 (vx_files_info): Indicate whether target has float or not.
1749 (vx_lookup_symbol): Complain, not error, if target gone.
1750 (vx_open): Print "Connected" msg before disabling immediate-quit.
1751 [FIXME: lookup_symbol and vx_open changes need testing.]
1753 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
1754 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
1755 contributor lines and update copyrights to 1991.
1757 Changes from an attempted H-PUX host port:
1759 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
1760 defines PT_ATTACH and PT_DETACH but not PT_KILL.
1761 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
1762 * remote-vx.c: include <sys/time.h> for HPUX.
1763 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
1764 "core_file_command" routine to BFD regime. May not work yet.
1766 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
1768 * xgdb.c: Replace X10 version with some VJ version.
1769 (FIXME: Its copyright assignment is not on record.)
1770 * xgdb.c: Update include files to X11R4 (Xaw crud).
1771 (xgdb_display_source, create_text_widget): fix call to
1772 get_filename_and_charpos. Rewack source window stuff for X11R4
1773 (gleaned from include files, and "nm's" of binary libraries, since
1774 I had no doc available).
1775 (append_selection, append_selection_word): Disable with FIXME
1776 since R4 changed interface here.
1777 (create_buttons): Add back the old set of buttons.
1778 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
1780 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
1781 Roll VERSION to 3.94 (not yet final though).
1783 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1785 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
1786 obstack_int_grow, obstack_int_grow_fast): Eliminate
1787 cast on left of assignment, which gives MIPS cc fits and is
1790 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
1791 F_ALIAS. Use printf, not fprintf, when not passing a file
1793 (compare_opcodes): Check that identical instructions have
1794 identical opcodes, complain otherwise.
1796 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
1797 was reported by Roland McGrath.
1798 (unimp): Only match if exactly zero instruction. (Roland)
1799 (branches and traps): Generate all variations of these
1800 instructions with macros, based on a single call that defines
1801 each condition name and its binary representation.
1802 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
1804 * valprint.c (val_print_fields): Take, and use, format parameter.
1805 This means that "p/x struct" again prints the elements in the
1806 desired format. Changed callers.
1808 * stack.c (frame_info): Use filtered output, and indicate wrap
1809 points. Remove kludgy formatting designed to avoid line wrap.
1811 * utils.c (wrap_here): If the line is already full (because
1812 we had printed a long indent or long wrapped string), do an
1813 immediate newline-and-indent.
1815 * m68k-pinsn.c (print_insn_arg): Bugfix from
1816 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
1817 instruction is incorrectly disassembled as bkpt #8.
1819 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
1820 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
1821 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
1822 and then will dump core (sometimes). I traced it back to an
1823 uninitialized symfile_name in psymtab_to_symtab.
1824 (const_vol_complaint): Add quotes to message.
1825 (define_symbol): Only believe line number if gcc_compiled.
1826 Avoid allocating symbol if we will not return it.
1828 Add target strata support so that newly established targets go
1829 into their right place in the target stack (e.g. a new exec file
1830 doesn't wipe out the ability to access the running process).
1832 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
1833 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
1834 and initialize it properly in all the targets.
1836 * target.h: Document strata. Change return type of push_target.
1838 * target.c (nomemory): new function for dummy memory access.
1839 (tcomplain): Rename complain, now also used in symfile.c.
1840 (push_target): Push targets within strata. New return value shows
1841 whether new target is on top of stack or not. Always keep dummy
1843 (target_files_info): Ignore dummy target.
1845 * core.c (core_open): Warn user, and skip accessing file, if the
1846 core target is not the topmost target in the stack.
1847 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
1850 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
1851 target_ops, it doesn't belong there since we have no regs there.
1852 Change name of target from machine => memory to clarify.
1854 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
1856 * Freeze version 3.93 for release.
1858 * Makefile.dist: Handle vx-share and nindy-share subdirs
1859 properly when building gdb.tar.Z.
1861 * symtab.c: lint; add no_symtab_msg to consolidate the messages
1862 printed in various places, so I could change just one copy.
1864 * dbxread.c, coffread.c: Change references to bfd->iostream
1865 to cast to FILE *, now that BFD avoids needing types defined
1866 in other header files.
1868 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1870 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
1871 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
1872 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
1873 (actually gcc -Wall).
1875 * dbxread.c: Remove first_global_sym, last_global_sym, since
1876 they are never referenced.
1878 * defs.h (baud_rate): Declare.
1879 main.c: Define it, and add the -b option to set it.
1881 * gdb-int.texinfo: Add text on how to define a new host or target
1882 architecture, prompted by Per Bothner's questions about MIPS
1885 * gdb.texinfo: Document "complaints". Change doc of -q since
1886 gdb no longer prints the copyright and blurb if you specify a file
1887 name to be debugged (just like Emacs). Add doc for Nindy-specific
1888 command line flags for specifying target serial port and such.
1889 Update copyright to 1991.
1891 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
1892 has taken over for us the job of ripping up executable files. The
1893 crud caused Per Bothner's port to not compile.
1895 * infrun.c (normal_stop): Avoid printing "Program exited
1896 normally" if we are in batch mode. This allows a GDB which
1897 executes a program on a target system, to behave like a Unix
1898 command (input from stdin, output to stdout, no extraneous
1901 * main.c (main): Allow additional machine-dependent command line
1902 options to be specified with the ADDITIONAL_OPTIONS,
1903 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
1904 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
1905 processing to occur just before the main loop with
1906 BEFORE_MAIN_LOOP_HOOK.
1907 (main): If a "core file" argument is specified, and it is not a
1908 core file, try it as a process ID to attach.
1909 (symbol_completion_function): Attempt to cope with
1910 "show screen-" TAB, not very successfully. This needs more work,
1912 (batch_file): New function, returns whether we are reading
1913 commands from an interactive tty on stdin, or from somewhere else.
1914 Called by normal_stop since it doesn't get from_tty passed down
1915 to it like many commands do.
1917 * remote-nindy.c: Handle command line options for nindy
1919 (nindy_before_main_loop): Prompt user for tty name if they
1920 don't specify it before getting to the interactive command loop.
1922 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
1923 and -r command line options. Also add hook before main loop
1924 to make it easy to specify a tty.
1926 * TODO: More things to do, one done.
1928 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
1930 * dbxread.c: Make complaint() calls pass pointer, not struct.
1931 Add complaints about badly formatted C++ type information
1932 (const/volatile indicator, and parse errors resulting in
1933 error_type). Fix C++ virtual member fn comment.
1934 (read_struct_type): Avoid bumping pointer if we got a parse
1935 error; this prevents our walking beyond the end of a string.
1936 Terminate loop on null char as well as semicolon.
1937 (process_one_symbol): Fix the LBRAC fix so that it uses the
1938 last previous SLINE, FUN, or SO record's PC address. C++ debug
1939 symbols did not have SLINE records in a useful order compared
1940 to the LBRAC records.
1941 (define_symbol): Handle "catch" records.
1943 * symtab.c (check_stub_type): Added new complain
1944 `stub_noname_complain' and added a consistency check to
1945 keep the debugger from crashing when finishing from an
1946 exception frame. A real fix will be needed later.
1948 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1950 * infcmd.c (attach_command): Make global.
1952 * Makefile.dist (REMOTE_OBS): Make these compile by default,
1953 but make them easy to comment out. Perhaps later they should
1954 be enabled by what CPU you configure for? FIXME.
1955 (VERSION): Roll to 3.93.
1956 (pinsn.o): Remove rule for obsolete file.
1957 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
1959 Run down a problem that manifested by printing the wrong function
1960 name in stack traces of read_ofile_symtab. Turned out that the
1961 problem was the SunOS 4.1.1 (and previous) C compiler outputs
1962 the LBRAC symbol with an address in the *data* segment, which
1963 blew our binary search through the blocks.
1965 * dbxread.c: Use the complain() facility consistently to bitch
1966 about problems in the symbol file we are reading.
1967 (finish_block): Add code to check the nesting of the blocks;
1968 complain and Procrust them to fit if wrong.
1969 (make_blockvector): Check the order of the blocks, complain
1970 [but don't cope] if wrong.
1971 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
1972 symbols to be sure their PC value is greater than the last SLINE
1973 (line number) symbol we've seen, complaining and adopting the
1974 SLINE PC value if wrong.
1976 * symfile.h (struct complaint, complaint_root, complain,
1977 clear_complaints): Add.
1978 * symfile.c (complain, complaint_root, clear_complaints): Add
1979 facility to deal with non-fatal complaints and to regularize their
1981 (symbol_file_add): Clear complaint counters to allow new complaints.
1982 (initialize_symfile): Add 'set complaints' and 'show complaints'.
1984 * dbxread.c (dbx_symfile_read): Remember the address and size
1985 of the string table for the main symbol file, so we won't read it
1987 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
1988 to avoid reading the string table yet again. Lint.
1989 (throughout): Improve filtered output, including word wrap.
1990 (read_range_type): Improve Bothner's fix to handle other types too.
1992 * utils.c: Improve line wrap implementation. Handle unlimited
1993 width by making chars_per_line unsigned.
1994 (puts_filtered): New, easy, function.
1996 * defs.h (puts_filtered): add.
1998 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
1999 call the identical sort_symtab_syms() in symfile.c instead.
2001 * expread.y: Suggest the `file' command rather than `symbol-file'.
2003 * command.h (enum var_types): Add zinteger for seroable
2005 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2006 nested if's into a switch.
2008 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2009 we did not stop because of a breakpoint (it must have been for
2010 some other reason, like a "stepi"), so don't print anything.
2012 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2013 doesn't include <sys/types.h>, old SunOS's require it for
2016 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2018 A test port of gdb-3.92.6 to the Sony NEWS.
2021 Don't normally link in remote- or vx stuff.
2022 Some of it doesn't compile, and it wastes space for 99% of the users.
2023 Remove reference to no-longer-used HAVE_VPRINTF.
2024 Fixed BFD_DEP typo to BFD_DIR.
2026 Fix cast in arg to bfd_h_getlong.
2027 Make char *prefix be const.
2028 Fix how certain range types are mapped into builtin unsigned int types.
2030 Remove 2 #includes. They cause errors (on Sony, at least),
2031 and aren't needed (they wern't in earlier versions).
2033 print_address_symbolic should never demangle labels
2034 (since it prints *assembler-level* labels).
2036 [This was superseded by the change to printcmd below.]
2039 Add some "volatile" return types to avoid warnings.
2040 If MISSING_VPRINTF add vprintf function and not just macro
2041 (since vprintf is used in printcmd.c).
2043 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2044 (The latter isn't grokked by some PCC-based compilers.)
2046 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2048 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2049 * nindy-share/coffstrip.c
2050 Added some forward declarations (otherwise, gcc complains
2051 about implicit extern redefined as static).
2053 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2055 Changes inspired by Per Bothner:
2056 * printcmd.c (print_address_symbolic): Take additional parameter
2057 specifying whether to demangle.
2058 (print_address): Pass in asm_demangle to control demangling.
2059 (print_address_demangle): New fn, takes explicit arg to control
2061 * utils.c: Add new vars demangle and asm_demangle, and let them
2063 (fputs_demangled): If !demangle, just print the argument.
2064 (fprint_symbol): If !demangle, just print raw symbol.
2065 * valprint.c (val_print): Call print_address_demangle rather than
2066 print_address, to cause demangling to depend on the global
2067 rather than assembler-level demangling setting.
2068 * WHATS.NEW, gdb.texinfo: Document.
2070 * main.c (show_command): Show all settings if no arg.
2071 (initialize_main): Make "info set" the same as naked "show".
2072 * command.c (cmd_show_list): Handle prefix commands in the
2073 list, and print the name of the setting as well as its English
2074 description and value.
2076 Allow gdb functions to specify where a line should wrap if it
2077 exceeds the size of a terminal line. Use it to make the output
2079 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2080 of the right size when screen width changes.
2081 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2082 (wrap_here): New fn, indicates a point in the output where we
2083 should wrap the line rather than just letting it overflow at a
2085 (fputs_filtered): Implement wrapping.
2086 (n_spaces): New fn, returns a pointer to N spaces.
2087 (print_spaces_filtered): Use n_spaces.
2088 * defs.h (n_spaces): Declare.
2089 * stack.c (print_frame_info): Wrap with 4-space indent after
2090 fn name and before filename and line number.
2091 * printcmd.c (print_frame_args): Wrap with 4-space indent
2092 before each argument name is printed.
2093 * valprint.c (value_print): Wrap with no indentation before
2095 (val_print_fields): Wrap with indentation relative to nesting
2096 level before each field name.
2097 (val_print): Wrap with nesting indentation before array elements.
2098 * command.c (do_setshow_command): Avoid extra newlines,
2099 wrap with 4-space indent around values printed, end with period.
2100 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2102 * breakpoint.c (breakpoint_1): Implement addressprint for
2103 "info breakpoints" display. Change file name and line number
2104 format to " at file:nnn" rather than " (file line nnn)".
2105 * gdb.texinfo: Document.
2108 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2110 Frozen for gdb-3.92.6 release.
2112 README, WHATS.NEW: Update for 3.92.6 release.
2114 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2115 coffread.o from configs since it is now built by default.
2116 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2117 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2118 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2119 from configs since it is now built by default.
2121 Makefile.dist: Update for release 3.92.6. Handle files that
2122 have been moved to ../include, ../getopt, or ../bfd. Add
2123 saber.suppress and tests directory. Add config.status to
2124 the release (it will say "none").
2126 coredep.c: Minor formatting fixes.
2128 These changes were made in early December but only checked in now:
2129 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2130 nindy-share/nindy.c: lint
2131 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2132 register values coming back from the target; we store values
2133 in target byte order everywhere.
2135 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2137 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2139 * valprint.c (cplus_val_print, val_print_fields): New functions,
2140 which print C++ objects. They conspire to avoid printing a
2141 virtual base class more than once, following all the twists and
2142 turns of C++ virtual base rules.
2143 (val_print): Call the above rather than do it by hand.
2145 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2146 symbol file, not for added files like shared libs. This really
2147 needs to be generalized to a timestamp per file.
2149 * core.c (cleanup_core): Avoid coredump if no core file.
2151 * config.gdb: Accept -host or -target in place of +host or
2154 * coffread.c (find_linenos): Avoid desupported BFD interface
2155 to line numbers. We still read them manually rather than using
2156 BFD's "generic" features.
2158 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2160 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2162 * Makefile.dist: Eliminate use of $< in explicit targets.
2164 * readline/Makefile: Use $< rather than $*.c, which does not
2165 include the VPATH in GNU Make.
2167 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2168 copies of tconfig/i960, added for global configuration
2169 compatability. All i960 versions can read both coff and b.out.
2171 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2172 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2175 * TODO: Think of more things to do.
2177 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2179 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2180 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2181 64-bit float conversion.
2183 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2184 equivalent to sun?os4 so global config works.
2186 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2188 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2190 * main.c: Only declare linesize once; declare pagesize not at
2191 all, since it is never used.
2192 (main): Clear newly allocated line before it is used.
2194 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2196 Further stabilization for the Intel 960.
2198 * Makefile.dist: Parameterize the location of the "include"
2199 and "bfd" directories, as well as "getopt". Add symfile.c.
2200 Link in both dbxread and coffread. Fix up "make depend" to
2201 rewack the locations of include, bfd, and getopt in its output.
2203 * README: Document moving include files, improve some of
2206 * coffread.c: Move common code out to symfile.c. Change
2207 symbol_file_command style interface to use new *_symfile_init
2208 and *_symfile_read interface under BFD. Use BFD internal
2209 info to locate line table, symbols, etc.
2211 * core.c (core_fetch_registers): Rename to get_core_registers
2212 to avoid confusion with fetch_core_registers.
2213 (register_addr): Move to coredep.c, which is already machine
2214 dependent. This leaves core.c pretty clean of dependencies.
2216 * coredep.c (register_addr): Accept this routine from core.c.
2218 * dbxread.c: Move common code (with coffread.c, etc) into new
2219 symfile.c. Each psymtab now contains a pointer to the
2220 format-dependent function that knows how to read it in. Make
2222 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2223 (process_one_symbol): Add code to complain about a "compiler bug
2224 we muzzle here", if we actually see it.
2226 * eval.c (evaluate_subexp): Insert missing "break" statements
2227 in code that determines whether a variable is an lvalue in
2228 memory, register, or whatever. I detected this via a compiler
2229 bug in which it *almost* mashed out the whole switch statement.
2231 * gdb-int.texinfo: Add minor sections on configuring gdb for
2232 release, and about the README file.
2234 * infcmd.c (registers_info): Fix formatting somewhat. Still
2235 not as pretty as before, but it handles byte swapping.
2237 * remote-nindy.c: If data cache routines are interrupted while
2238 waiting for the remote end, be sure that any uninitialized cache
2239 blocks are on the free list, not on the valid list!
2241 * symfile.h: Flesh out this header file with all the various
2242 routines and variables that have been merged in from dbxread.c
2243 coffread.c, and symtab.c to symfile.c.
2245 * symfile.c: New file, containing code common to dbxread.c,
2246 coffread.c, and some code from symtab.c. All generic code for
2247 reading symbol files should be in here now.
2248 (unrecord_misc_function): Remove unused function.
2250 * symtab.h: Remove file-reading things to symfile.h.
2252 * symtab.c: Remove file-reading things to symfile.c.
2254 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2255 to decode i960 fault types.
2257 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2258 target.c: Change type of the "resume" function from int to void,
2259 since its result was never used.
2261 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2263 * main.c: Replace "stupid" with "caution"; you now "set caution
2266 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2268 * infcmd.c (do_registers_info): Call val_print to deal with the
2269 byte order of the registers being printed. FIXME, this makes
2270 the formatting of the output uglier.
2272 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2273 defined, call it for signals the debugger doesn't itself use.
2274 The i960 uses this for more detailed fault information.
2276 * remote.c (remote_open): If arg is null, print help rather than
2279 * sparc-xdep.c (register_valid): Avoid declaring size, since
2280 various modules will think of various sizes depending on the
2281 architecture of their tm-file. FIXME, we need protection against
2282 actually entering one of those modules, which would clobber
2283 storage if not for the target architecture compiled into gdb.
2285 * stack.c (up_command, down_command): Always print the frame
2287 (up_silently_command, down_silently_command): New commands
2290 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2292 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2293 more parameters than it used to.
2295 * findvar.c (registers): Increase slop to 256 bytes, which should
2296 protect us against even most RISC machines with large register
2298 (locate_var_value): Move declaration inside related ifdef.
2300 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2301 throughout, to avoid throwing away buffered input from the board.
2302 (nindy_wait): Supply_register takes addr_of_value, not value.
2303 (i960_print_fault): Renamed from i80960_fault.
2304 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2305 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2307 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2308 we can set the PC in the call to proceed(). Unpush nindy_ops
2309 before pushing it on top, to avoid message to user. Eliminate
2310 commentary from Unix machines that just misleads here.
2311 (reset_command): Fix error message to suggest target command.
2313 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2315 Release 3.92.5 as frozen.
2317 Stabilize the merged release...with help from lint, Saber C,
2320 Everywhere: Add include files needed to declare return types
2321 of functions called.
2323 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2325 * breakpoint.h: Add undeclared breakpoint functions, and some
2326 functions for display handling since I couldn't think of a better
2329 * breakpoint.c (insert_breakpoints): Make code for disabling
2330 shared library bkpts more likely to work. It's used when we
2331 rerun a program and stop before the shared library has been
2333 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2334 cast from pointer, so it squeezes through catch_errors.
2335 (bpstat_stop_status): Fix logic broken some time ago. We now
2336 always create a bpstat if the stop address matches a breakpoint,
2337 even if we don't stop there -- just like the old code used to do
2338 before I got my fingers into it (sigh).
2339 (breakpoint_1): Print "ignore count" after "stop only if"
2340 condition, since that's how it actually works.
2341 (mention): Handle watchpoints as well as breakpoints.
2342 (watch_command): use set_raw_breakpoint and mention to do most
2343 of the work (and initialize all the fields!). Only pass one
2344 arg to parse_c_expression, since that's all it takes.
2346 * command.c (not_just_help_class_command): Rename arg to args
2347 since we ignore "unused argument" warnings on vars named "args".
2348 inflow.c (child_terminal_info): ditto.
2349 infptrace.c (kill_inferior): ditto
2350 main.c (catch_errors, version_info, quit_command, pwd_command,
2351 source_command, dump_me_command, editing_info,
2352 set_history_size_command, set_history, show_history,
2354 stack.c (locals_info): ditto
2355 target.c (target_files_info): ditto
2356 valprint.c (set_input_radix, set_output_radix): ditto
2358 * core.c: Remove old variables for handling core and exec file
2359 sections (data_start, data_end, stack_start, stack_end,
2360 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2361 text_end, exec_data_start, exec_data_end, text_offset,
2362 exec_data_offset, data_offset, stack_offset). They're
2363 superseded the more general build_section_table and
2365 (get_exec_file): Mention the `file' command.
2366 (read_memory_check): Rename to memory_error, and only call it
2367 in the case of an actual error.
2368 (read_memory, write_memory): call memory_error.
2369 (core_fetch_registers): Register section name is ".reg".
2371 coredep.c: Remove a bunch of crud now that all this file does
2372 is pull the registers out of a core file.
2373 (fetch_core_registers): Rewrite to actually work, I hope.
2375 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2376 Replace index() with strchr(). Remove all the pre-BFD macro
2377 definitions for accessing the symbol file.
2378 (struct dbx_symfile_info): Encapsulate the information that
2379 dbx_symfile_init needs to pass to dbx_symfile_read in this
2382 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2383 dbx_symfile_discard): Rearrange symbol file reading to divide
2384 the format-specific part from the format-independent part,
2385 leaving the format-independent part such as file name expansion
2386 and opening in symtab.c. This replaces
2387 partial_symbol_file_open and partial_symbol_file_read.
2388 Symbol_file_read, add_file, add_file_target_command,
2389 add_file_addr_command move to symtab.c. Pass an explicit
2390 "mainline" flag for when reading the main symbol table, rather
2391 than relying on the offset address to be zero or nonzero.
2393 (dbx_symfile_read): Don't allow void *'s to be printed as
2395 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2396 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2397 macro" debug version really work.
2398 (read_dbx_symtab): Remove unref'd parameter inclink.
2399 Avoid swapping N_SLINE symbols, for speed.
2400 Merge N_TEXT!N_EXT case with the other external symbol
2401 definitions' case. Add comments.
2402 (start_psymtab): Allocate the symfile name in the psymtab on
2403 the psymbol_obstack, rather than using the caller's storage.
2404 (end_psymtab): Only allocate a dependencies list if there are
2406 (psymtab_to_symtab_2): Use BFD when reopening file to read
2407 its symbols for real.
2408 (read_struct_type): Add FIXME comments where it needs work
2410 (read_huge_number): Add FIXME about overflows.
2411 (read_range_type): Add FIXME about comparing a long to 1<<32.
2413 * coffread.c: Minor changes to move things closer to the new
2414 regime with symtab.c and dbxread.c Major work is still needed
2417 * exec.c (exec_file_command): Remove old variables (see core.c
2419 (xfer_memory): If memory transfer is right at the end of a
2420 section, don't lose.
2422 * findvar.c (get_saved_register): If value is in a real
2423 register, LVAL is lval_register, not lval_memory.
2425 frame.h: Declare print_sel_frame and record_selected_frame.
2427 gdb-int.texinfo: New file, for GDB internals documentation.
2428 Very simple, unformatted doc of cleanups is there for now.
2430 gdbcore.h: Remove obsolete variables that described a.out
2431 section addresses and offsets. (See core.c above.)
2432 Declare fetch_core_registers and registers_fetched.
2434 getopt.c: Declare char *alloca(); even on SPARC.
2436 infcmd.c (run_command): Call target_kill rather than
2438 (step_command, next_command, stepi_command, nexti_command):
2439 Declare from_tty parameter even though we don't use it.
2440 (run_stack_dummy): argument BUFFER is a char array, not
2441 a pointer to REGISTER_TYPE.
2442 (finish_command): using_struct_return needed a value *,
2443 not a struct symbol *.
2445 * infptrace.c (child_xfer_memory): To avoid dependency on
2446 where sections are in memory, try PT_WRITE_D and if that fails,
2447 try PT_WRITE_I. Most Unixes don't care which you use.
2449 * infrun.c (step_resume_break_shadow): Change to array to
2450 match other breakpoint shadow storage.
2451 (clear_proceed_status): Pass address of bpstat to
2452 bpstat_clear, not the bpstat itself.
2453 (child_create_inferior): FIXME comment about if the child
2455 (start_inferior): Remove old function.
2456 (child_open): Use target_kill rather than kill_inferior.
2457 (wait_for_inferior): Ditto.
2458 (insert_step_breakpoint, remote_step_breakpoint): Use
2459 new step_resume_break_shadow.
2461 * inftarg.c (child_wait): If all child processes die,
2462 pretend that the one being waited for exited with signal 42.
2464 * main.c (command_line_input): When scanning for comments,
2465 don't coredump on unclosed quotes.
2466 (quit_command): Use target_kill rther than kill_inferior.
2467 (_initialize_main): Rename class_user from "user" to
2470 * printcmd.c (print_command_1): Initialize "fmt" if no format
2471 is specified by the user.
2472 (print_frame_args): Only add to args_printed if we are
2473 actually fetching args from the stack (avoiding undefined
2475 (_initialize_printcmd): Remove bogus \{ from string.
2477 * remote-eb.c (eb_open): Avoid coredump on no argument.
2479 * remote-nindy.c: Bring out of Intel environment into new
2480 target environment. Remove all conditional compilation on
2481 I80960. Massive hacking throughout.
2482 (nindy_xfer_inferior_memory): New routine stolen from
2484 (nindy_create_inferior): New routine pieced together, probably
2485 not quite working yet.
2486 (nindy_ops): New target_ops struct for nindy.
2488 * remote-vx.c: Use write_memory rather than target_write_memory
2489 to get error checking.
2490 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2492 (vx_create_inferior): Use target_terminal_ours...
2494 * signame.c (_initialize_signame): Always initialize, since
2495 we need the table for things other than psignal.
2497 * solib.c (solib_add): Use symbol_file_add, not add_file.
2498 (solib_address): Return boolean result rather than struct
2499 pointer which nobody else knows the type of.
2501 * sparc-tdep.c, valops.c: Use write_memory rather than
2502 target_write_memory, to get error checking.
2504 * stack.c (locals_info, catch_info, args_info,
2505 get_selected_block, frame_command, up_command): Use
2506 target_has_stack, rather than have_inferior_p or
2509 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2511 * symfile.h: New file, defining the interface between the
2512 generic and object-file-specific symbol reading code.
2514 * symtab.c: Move generic symbol-reading interface to symtab.c,
2515 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2516 table to map BFD targets to symbol-reading modules in GDB.
2517 Change index to strchr.
2518 (lookup_struct_elt_type): Use error() rather than hand-made
2519 simulations thereof.
2520 (lookup_partial_symbol): Speedup slightly when length == 0.
2521 (symbol_file_add): New function.
2522 (symbol_file_command): Call it.
2523 (symfile_open, symfile_init): New function.
2524 (add_file_target_command, add_file_addr_command): moved from
2527 * target.c (target_command): use target_kill.
2529 * target.h (target_files_info): Don't declare, never called
2532 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2533 files to determine stack end address.
2535 * valarith.c (value_x_binop, value_x_unop): Change error message
2536 to be more useful. Pass proper argument to value_struct_elt.
2538 * valops.c (value_assign): FIXME comment that long long
2539 bitfields will break here.
2541 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2542 Update `make saber_gdb' to work better.
2544 * TODO: A woman's work is never done.
2546 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2547 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2548 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2549 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2550 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2551 valops.c, valprint.c, exec.c: Lint.
2554 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2556 Continuing Intel 960 port merge of GDB.
2558 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2559 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2560 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2561 Wack over "make depend" so it handles files in subdirectories
2562 vx-share, nindy-share, bfd, and in the current directory.
2564 * blockframe.c (get_prev_frame_info): Remove fatal error
2565 if stack not defined.
2567 * core.c (core_open, core_detach): New functions that handle
2568 the old "core-file" command as "target core" and "detach" instead.
2569 (core_file_command): Call them.
2570 (core_xfer_memory): Use common routine xfer_memory.
2572 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2573 dbxread now uses bfd for everything but symbol reading itself.
2574 BFD internals are used to drag out the relevant file offsets.
2575 (partial_symbol_file_open): Change args all around for BFD.
2577 * symtab.c: Rename "value" to "val" everywhere, so we can
2579 (symbol_file_command): New command, moved from dbxread.c
2580 and coffread.c. It uses BFD to read the file, then vectors
2581 based on its type, to dbx or coff symbol readers.
2582 * symtab.h: Extern a few vars for symbol_file_command.
2584 * target.h: Breakpoint takes a char * save area, not a char **.
2586 * valprint.c (val_print): When unpacking bitfields, offset
2587 the address in gdb of the value, if it is declared with a shorter
2588 type. Remove the last "runtime kludge test" of host byte order.
2590 * utils.c: Remove old my_bfd_read routine.
2592 * stack.c (frame_info): Use target_has_stack. Print program counter
2593 register's actual name rather than "pc", since it's called the
2594 "ip" (instruction pointer) on the i960 (sigh).
2596 * target.c (target_command): Add command for selecting a target
2597 type and calling its open routine. This is used for initiating
2598 communication with a particular target, in a generic way.
2600 * tm-i960.h: Update for modern gdb. Remove semicolons from
2601 various macros. Handle reading struct return convention, and
2602 error-out attempts to return structs with the "return" command.
2603 Be sure gdb doesn't think we know how to call functions in the
2606 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2607 to i960_xxx in lower case.
2608 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2609 not being defined yet.
2611 * remote.c (remote_open): Call start_remote to initialize
2612 wait_for_inferior during open.
2613 (remote_xfer_inferior_memory): Return length written rather
2616 * remote-vx.c (target_command -> vx_open): Use new generic
2618 * remote-eb.c, inftarg.c, exec.c: ditto.
2620 * infrun.c: Fix comments.
2621 (attach_program -> child_open): Use new generic target command.
2622 (wait_for_inferior): Clear saved register values before target_wait,
2623 so target_wait can set some of them if convenient.
2625 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2626 Return success indicator, not void.
2627 (child_xfer_memory): Avoid fetching initial word if we'll
2628 overwrite it anyway.
2630 * infcmd.c (attach_command): Use new generic target open routine.
2631 (_initialize_infcmd): Update doc on attach and detach commands.
2632 (do_registers_info): Merge in a byte-order problem as a FIXME
2635 * findvar.c (find_saved_register): Avoid problem in current frame.
2636 (read_relative_register): Ditto.
2637 (write_register): Convert byte order on the way out.
2639 * exec.c (file_command): Add.
2640 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
2641 (xfer_memory): Common function between core_xfer_memory and
2643 (exec_xfer_memory): Use it.
2645 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
2647 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
2648 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
2649 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
2651 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
2653 Merge Intel 960 port of gdb, continuing...
2655 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
2656 symbol_file_command): Pass from_tty arg to hush 'em up.
2658 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
2659 Add magic numbers for 960 COFF format.
2661 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
2663 Merge Intel 960 port of gdb, from Intel "1.2" release.
2665 CHANGE_LOG entries from their port, which was based on
2668 Thu Sep 6 11:02:22 PDT 1990
2669 Remove temp file if download is interrupted.
2671 Wed Aug 1 09:08:33 PDT 1990
2672 Now uses binary protocol to talk to NINDY.
2673 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
2674 Times out after 5 seconds when trying to talk to NINDY.
2676 Tue May 29 12:54:49 PDT 1990
2677 Added variable baud rate (-b switch).
2678 Source code reorganization.
2680 Thu Apr 26 11:09:55 PDT 1990
2681 More cleanup of batch mode; specifically, execute "-s", "-e", and
2682 "-se" switches as soon as they are encountered on the invocation line.
2684 Fri Apr 20 13:47:15 PDT 1990
2687 Thu Apr 19 09:54:28 PDT 1990
2688 Add 'reset' command.
2690 Wed Apr 18 09:48:07 PDT 1990
2691 After opening remote tty, wait for 1 second to go by without input
2692 from it before trying to talk to NINDY (fixes problems with the
2693 Heurikon HK80/V960E).
2695 Mon Apr 4 16:33:05 PDT 1990
2696 Some output was not being suppressed in 'batch' mode.
2698 Thu Mar 22 15:31:11 PST 1990
2699 Ask user if old symbol table should be deleted when new file is
2702 Allow user to run a program downloaded before gdb960 was brought up.
2704 Correct "exec-file" help message for i80960 context.
2706 Correct bug in calculating user space address: could occasionally
2707 corrupt user program.
2709 Make sure to zero low-order bits in rip's because of bug in 960CA
2710 A-step part: could cause operation faults when "next"ing across
2713 Correct bug that made it impossible to get source line numbers for
2714 code loaded at addresses higher than 0x7fffffff.
2716 Wed Jan 10 12:43:22 PST 1990
2717 Open remote tty for exclusive use.
2719 Fri Jan 5 12:14:42 PST 1990
2720 Correct disassembly (CA manual was right after all):
2721 opcode for sysctl is 0x659
2723 Mon Oct 23 12:03:04 PDT 1989
2724 Use G960BASE and G960BIN environment variables to find 'sx' utility.
2726 Mon Oct 16 14:15:09 PDT 1989
2727 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
2729 Mon Oct 2 15:56:31 PDT 1989
2731 Added 960CA disassembly support.
2733 To simplify maintenance:
2734 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
2736 - eliminated opcode.h: incorporates tables into i960-pinsn.c
2737 - moved 960-specific routines from i960-pinsn.c to i960-md.c
2738 - made disassembly interface identical to that in gdmp960.
2742 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
2744 * target.h: Allow targets to stack. Add target_has_memory,
2745 _registers, etc. Restructure memory access and "info files"
2746 to walk the target stack.
2747 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
2748 target.c: Change tables to match target.h.
2749 * inflow.c (child_mourn_inferior): pop child_ops.
2750 (generic_mourn_inferior): Use new has_stack flag.
2751 * infptrace.c (child_xfer_memory): New memory regime.
2752 * inftarg.c (child_files_info): New "info files" regime.
2753 * remote-eb.c: New memory regime, new info files.
2754 * remote-vx.c: New memory regime, new info files. Now use
2755 separate targets for VxWorks attachment to machine, and
2756 actually running a process under VxWorks, since one has
2757 stack & execution & regs and the other doesn't.
2758 * remote.c: New memory regime, new info files.
2759 * sparc-xdep.c (fetch_core-registers): New memory regime.
2760 * target.c: New routines and support for stacked targets,
2761 new memory regime, new info files regime.
2764 Generalize section handling for an arbitrary number of sections,
2765 including use of the new BFD (binary file) library.
2766 * gdbcore.h: Add struct section_table.
2767 * exec.c (build_section_table): Iterate all sections and
2768 record what gdb needs to know about them.
2769 (exec_command): Use it.
2770 (exec_xfer_memory): Use the table.
2771 (exec_files_info): Print the table.
2772 * core.c (core_file_command, core_xfer_memory, core_files_info):
2774 * source.c (find_source_lines): Use bfd_get_mtime.
2775 * dbxread.c: Quick changes to make it compile with new BFD.
2776 * utils.c (error): Avoid using bfd_error in generic routines.
2778 * core.c (core_fetch_registers): Get from the ".regs" section of
2780 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
2782 * inferior.h (attach_flag): Export.
2783 * infcmd.c (run_command): use new target_create_inferior.
2784 * infrun.c (child_create_inferior): Don't return result.
2785 * Makefile.dist (VERSION): 3.91.4.
2787 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
2789 * breakpoint.c (bpstat_num): Handle breakpoints which have
2790 since been deleted, such as temporary breakpoints.
2791 infcmd.c (program_info): ditto.
2793 * core.c (core_file_command): Display the frame where the core
2798 * remote-vx.c (target_command): Merge in target command from
2799 targ-vx.c. A few other cleanups.
2801 * TODO, Projects: Lots more stuff to do...
2803 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
2805 Massive changes to wall off the remote-debugging interface
2806 behind a function vector. The port to handle VxWorks targets
2807 is also part of this.
2809 All files: Replace references to renamed functions,
2810 remove references to remote_debugging, remove references to
2811 have_include_file, have_core_file in favor of target_has_stack,
2812 target_has_memory, etc.
2814 * Modularize the breakpoint interface.
2815 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
2816 a breakpoint instruction.
2817 breakpoint.c: struct breakpoint's shadow_contents now sized as
2819 (insert_breakpoints): Vector to target to install breakpoints.
2820 (remove_breakpoints): Vector to target here too.
2821 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
2822 sparc-tdep.c (single_step): Use new breakpoint interface for
2823 the single-step breakpoints.
2824 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
2825 New file, contains routines to insert and remove breakpoints by
2826 reading out the old contents and later replacing them. This is
2827 how ptrace breakpoints work, and many remote systems as well.
2829 * tm-vxworks68.h: New config file, overrides a few things for
2830 Wind River's preferences.
2832 * target.h: New file, for transfer vector used to talk to the
2833 inferior (child, attached, core, exec, remote, etc). All accesses
2834 to the thing being debugged should come through these vectors.
2835 target.c: New file, routines to handle transfer vector.
2836 (various files): Add transfer vectors XXX_ops for the various
2837 targets and pseudo-targets (core files, etc) we support.
2839 * breakpoint.c (bpstat_stop_status): Further explorations of
2840 watchpoints and why things don't work all the time.
2841 (bpstat_alloc): New fn to allocate a bpstat and chain it.
2843 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
2844 the local gdbinit if it doesn't already have it.
2846 * core.c (core_ops): add and install.
2847 Allow core debugging without exec file.
2849 * dbxread.c (free_and_init_header_files): Merge two fns.
2850 (end_symtab): Free named symbol table when a new version comes in.
2851 (read_dbx_symtab): Relocate all kinds of symbols with base
2852 address. First step toward handling different text, data, bss
2854 (add_file_addr_command): Renamed add_file_command.
2855 (add_file_command): Vector to remote handler.
2856 Add "load" as an alias for "add-file" command.
2858 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
2859 non-returning functions.
2861 * exec.c: Add exec_ops, and push it as a target when an exec
2864 * infcmd.c (run_command): Pass executable file name and arg list
2865 separately when starting an inferior. Permit "run" when no exec
2866 file is specified, for VxWorks.
2867 (detach_command): Move to child_detach in inftarg.c.
2869 * inftarg.c: New file. Unix-child-specific routines, and the
2870 child_ops structure.
2872 * inferior.h (registers): Export "registers" as the way for
2873 target dependent register handlers to find gdb's local copy of
2874 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
2875 since it is now used by places that want wait_for_inferior to
2876 handle the grunge but want to see every trap from the inferior.
2878 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
2879 Eliminate remote_debugging hooks in terminal handling.
2881 * infrun.c: Replace start_inferior with child_create_inferior.
2882 Move all the hair of Unix shells and ptrace idiosyncracies into
2883 child_create_inferior, so remote handlers don't have to deal.
2884 Remove running_in_shell. Rename stop_after_attach to
2885 stop_soon_quietly, and use it in a few other places where we want
2886 to just call wait_for_inferior and get control back on the first
2887 trap. trap_expected now never takes a value > 1.
2888 (init_wait_for_inferior): Initialize static vars when a new
2891 main.c (gdbinit): Add new hook for .gdbinit file name, let
2892 it be overridden by config files as GDBINIT_FILENAME.
2893 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
2894 Both of these are used for VxWorks gdb.
2896 mcheck.c: rename include file "gmalloc.c" to avoid problems
2897 with system include file "malloc.c".
2899 param-no-tm.h: New include file, same as param.h but does not
2900 include the default "tm.h" file. This is used in files where
2901 the target is known, e.g. remote-eb.c or sparc-xdep.c.
2903 param.h: Now just a shell that includes tm.h and param-no-tm.h.
2905 remote-vx.c: New file, VxWorks remote debugging support. Uses
2906 RPC routines that are shared with the target system, in directory
2909 remote.c: Vectorize remote interface.
2911 source.c: Globalize source_path, and make an alias "l" for "list"
2912 since we now have the "load" command.
2914 sparc-xdep.c: Use new param-no-tm.h.
2916 symmisc.c (free_named_symtab): Add new function from Wind River.
2917 However, ifdef it out for now while we think about what it should
2920 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
2922 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
2923 non-Unix-children handle this with their own code in the target
2926 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
2927 source and target lists. Add vx-share to default list of include
2928 directories. Add new files to src and target lists: mem-break,
2929 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
2930 ${srcdir} versions of munch and createtags are used.
2932 * valops.c (find_function_addr): Split out of call_function.
2933 (call_function_by_hand): Rename call_function; this function
2934 calls functions in the target by laboriously patching the target
2935 word-by-word with the right stack, args, regs, etc.
2938 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
2940 Handle AMD 29000 a bit better.
2942 * remote-eb.c (readchar): Mask received char log to make it readable.
2943 (remote_start): Pass arguments down to executing program.
2944 Make startaddr unsigned.
2945 infrun.c (start_inferior): Accept args, pass them to
2947 infcmd.c (run_command): Pass args down to start_inferior.
2949 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
2950 the target object file format.
2951 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
2953 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
2954 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
2956 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
2958 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
2959 * TODO: We did a few things, we have more to do though.
2961 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
2962 * inflow.c (inferior_died): Clear deferred stores.
2964 * Debug problems with dummy frames and calls to the inferior.
2965 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
2966 * sparc-tdep.c (do_restore_insn): Simplify.
2967 (sparc_frame_find_saved_regs): Simplify and fix what we find.
2968 (sparc_push_dummy_frame): Simplify and fix what we push.
2969 (sparc_pop_frame): Slightly more hair here, deciding whether
2970 we are restoring a saved PC or returning to a return address in %i7.
2971 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
2973 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
2974 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
2975 * obstack.h (chunkfun): ditto.
2976 * defs.h (xmalloc, xrealloc): ditto
2978 * utils.c (quit): Grab the terminal from the child if necessary.
2980 * inflow.c (term_status_command): Rename to term_info, change
2983 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
2984 (is_delayed_branch): Speed up.
2985 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
2986 Still missing some float ops, and needs testing.
2988 * Support for input and output radixes other than base 10
2989 * defs.h (input_radix, output_radix): Declare.
2990 * expread.y (yyparse, parse_number): Handle changes of input
2991 radix, and ambiguous names-or-numbers in radixes >10.
2992 * printcmd.c (print_scalar_formatted): Print formatted hex
2993 numbers in varying column widths.
2994 * valprint.c (val_print): Use output_format to print scalar ints.
2995 (set_input_radix, set_output_radix, set_radix): Create.
2996 (set_output_radix): Set output_format from output_radix.
2997 (_initialize_valprint): add `set radix' but leave the others off.
2999 * main.c (execute_command): Let stupid questions be turned off.
3000 (_initialize_main): Handle "set stupidity", etc.
3002 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3003 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3005 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3007 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3008 bfd stuff is still screwed up, but with some manual work, it
3011 * breakpoint.c (bpstat_do_actions): Start over if a command
3012 proceeds the inferior, since the inferior will have stopped and
3013 will need to have its new stop-actions taken care of.
3015 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3016 compiler fits, simplify it.
3018 * gdb.texinfo (directory command): Doc new dir command.
3019 source.c (directory_command): "dir" now puts things on the front
3020 of the path, moves dups up front, and handles multiple names
3021 on the command line, inserting each one in order. It also
3022 blows away cached line and full_filename info.
3024 * stack.c (backtrace_command): Skip "more stack frames follow"
3027 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3028 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3029 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3030 The only odd one was Gould NP1, which had defined vprintf to
3033 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3034 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3035 variable, inspect_it.
3036 valprint.c (print_string, val_print): Use the global inspect_it
3037 to indicate whether to print in Epoch style or normal style.
3039 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3041 * printcmd.c (call_command): add an alias for the "print" command
3042 which runs expressions and doesn't print the result if void.
3043 (print_command_1): implement it.
3045 * command.c: Remove #if 0'd code. Initialize all the fields
3046 in add_cmd (). Rename do_nothing_command to
3047 not_just_help_class_command, and make it externally visible.
3048 command.h: add user_commands to struct.
3049 * main.c (define_command): Don't overload c->function with a char
3050 string as well as a function pointer.
3052 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3053 calling convention of value_struct_elt () that got dropped in
3056 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3057 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3059 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3061 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3062 until a good time (e.g. when we are about to run the child),
3063 saving ptrace calls.
3064 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3065 * tm-sparc.h: define DO_DEFERRED_STORES.
3067 * sparc-xdep.c (store_inferior_registers): when storing float
3068 registers, don't store stack regs too. When storing the SP,
3069 however, DO store the stack regs too. This fixes a bug in which
3070 the dummy frame is not recognized when a call_function finishes,
3071 because its frame pointer (in the stack regs) was never
3073 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3074 even though we don't know how to read them from an inferior.
3075 valops.c (call_function): Comment about storing SP.
3077 * infrun.c (save_inferior_status): Save away the original bpstat
3078 chain so it can be restored later. Install the copied version for
3079 use by whoever saved the status. It will be blow away by
3080 restore_inferior_status, and the original chain restored. This is
3081 important for people who have pointers into the original.
3083 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3084 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3085 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3088 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3090 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3091 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3092 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3094 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3096 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3097 Store the baseclasses in a type struct starting from array element
3098 0 rather than from the unusual array element 1.
3100 dbxread.c: the above.
3101 (virtual_context): Add
3102 Read new debug information about which virtual function table
3103 a virtual function is from, and store it in fn_field.fcontext.
3105 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3106 TYPE_FN_FIELD_STATIC_P.
3108 symtab.c: the above.
3109 valops.c: the above. Handle pointer casts of object *'s.
3110 (search_struct_method): Add.
3111 (value_struct_elt): First arg is now a pointer to a value, and is
3114 valprint.c: the above.
3115 values.c (value_virtual_fn_field): Add type arg. Handle
3116 offsetting to the proper object when calling virtual fns.
3118 (baseclass_addr): Add valuep arg.
3120 * README: Document the current state of BFD config (missing).
3121 * TODO, ChangeLog, Makefile.dist: Roll version.
3122 * WHATS.NEW: Add summary of changes since 3.5.
3124 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3126 * dbxread.c (read_struct_type): Clear bit vectors whenever
3128 symtab.c (B_CLRALL): define.
3130 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3131 using == rather than =. Huh... This fixes the dreaded problem
3132 wherein builtin_type_int becomes TYPE_CODE_FLT.
3134 * core.c (info_files): Show the inferior pid.
3136 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3137 already knows how to look in the source directory.
3139 * Remove psymtab hair from many places. Remove duplicated code
3140 for searching symbol tables. Hide psymtabs from most places.
3141 Make it fast to get from a psymtab to its symtab.
3143 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3144 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3145 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3146 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3147 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3148 new symtab completely. New psymtabs get symtab pointer
3149 initialized to zero. Remove MI warning printf.
3150 symtab.h: Comments. Add psymtab to symtab pointer.
3151 (PSYMTAB_TO_SYMTAB): New macro.
3152 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3153 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3155 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3157 (print_frame_info): Avoid special-casing symbols that have not yet
3160 * source.c (open_source_file): Quick path if we have already
3161 located the source file by its full name.
3163 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3164 find_pc_psymtab. When a name is found in the misc function
3165 vector, search the symbol table for its mangled name, not the
3166 name that the user typed.
3168 * bfd.h: Fix missing comment terminators, make #endifs match.
3170 * valarith.c (value_less): Handle unsigned int comparisons.
3171 Add FIXME about pointer compares, which assume host and target
3172 pointers are the same.
3174 * command.c (do_nothing_command): lint
3175 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3176 fix comments on debug symbol format for visibility. Actually set
3177 visibility of symbols.
3178 main.c (echo_command): lint; use <readline/history.h>.
3179 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3180 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3181 pointing past end of allocated memory; saber complains.
3182 obstack.h: Declare the external functions that we use.
3183 valarith.h: use <string.h>
3184 solib.c (solib_add): lint.
3186 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3188 * main.c (initialize_main): Default info_verbose to off, now that
3189 symbol reading is fast.
3190 (quit_command): Avoid clobbering exec_bfd while quitting.
3192 * Initial BFD (binary file diddling library) merger:
3193 coffread.c: Change AOUTHDR to struct exe_hdr.
3195 core.c: initialize initialized data at compile time.
3196 (core_file_command): Move from coredep.c, convert to bfd.
3197 (xfer_core_file): Convert to bfd.
3198 exec.c (exec_file_command): use bfd routines.
3200 mips-tdep.c: Remove exec_file_command and friends.
3203 * coredep.c: (fetch_core_registers) Convert core_file_command to
3204 fetch_core_registers.
3205 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3207 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3208 (my_bfd_read): More bogosity, which I don't think we call.
3209 (program_name): Remove this atrocity asap!
3211 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3214 values.c: allocate_repeat_value was not clearing the
3215 optimized_out field.
3216 (value_static_field): minor stylistic fix (wrong macro was used).
3217 valops.c (value_struct_elt_for_address): didn't work for C++
3220 * signame.c (_initialize_signame): Initialize signal names once.
3222 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3223 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3224 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3226 * remote-eb.c: Support user-settable baud rates on the serial port.
3228 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3230 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3232 * tconfig/sun3os4: Remove warning about native assembler,
3233 since it also occurs in the xconfig file.
3235 * findvar.c (registers): Allocate some slop after `registers'
3236 to prevent stray accesses from trashing the next variable.
3238 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3239 on the sun-3, by changing the #ifdef from `sun3' (which is not
3240 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3241 vars, which happened to follow `registers' in the executable.
3243 * readline/history.c (history_search): Heed gcc-2's advice
3244 and parenthesize && inside ||).
3246 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3247 tm-29k.c: Insert FSF copyright headers.
3249 * remote-eb.c: Better comments.
3251 * Makefile.dist: Update to 3.91.6.
3252 * TODO: note PREPARE_TO_STORE problem.
3254 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3256 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3258 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3260 * infrun.c (wait_for_inferior, at end): Don't set up
3261 prev_* if the inferior no longer exists.
3263 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3264 CANNOT_EXECUTE_STACK.
3265 valops.c (call_function): Use it.
3267 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3269 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3270 infrun.c (wait_for_inferior, 2 places): Use it.
3272 * values.c (value_being_returned): Only use
3273 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3275 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3276 right thing for remote-eb.c.
3278 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3279 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3281 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3282 (FRAME_FIND_SAVED_REGS).
3284 * findvar.c ({fetch,store}_registers): Check for
3285 REMOTE_{FETCH_STORE}_REGISTER macro.
3287 * findvar.c (get_saved_register): Add argument lval and
3288 change meaning of argument addr.
3289 findvar.c: Change calls to get_saved_register to reflect
3290 new calling convention.
3291 valops.c (value_assign): Use get_saved_register instead of
3292 find_saved_register.
3294 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3296 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3297 an (uninitialized) pointer to one. Use "&" when passing it
3300 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3302 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3305 * coffread.c (symbol_file_command): Put semicolon after
3307 Put safe_to_init_tdesc_context in #if defined (TDESC).
3308 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3309 coffread.c: #include <sys/stat.h>.
3310 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3311 Add missing ')' in check for "lc%" and friends. Remove
3313 Declare read_one_sym() at top of file.
3314 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3315 MC68WRMAGIC can have the same value without causing a duplicate
3318 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3320 * Allow a Makefile to be built without building the
3321 tm and xm file links that screw up builds in subdirectories.
3322 This is done with `config.gdb none', then you can do things
3323 like `make gdb.tar.Z'.
3324 * tconfig/none: Config file for no target system
3325 * xconfig/none: Config file for no host system
3326 * config.gdb: If no TM or XM files are called out by the
3327 host or target file, don't make links for them.
3329 * cplus-dem.c: Add documentation.
3331 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3332 simple error, so the user's gdb doesn't crash due to some object
3333 file problem (e.g. somebody is rebuilding the file out from under
3336 * printcmd.c (print_address_symbolic): demangle the symbol.
3338 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3339 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3340 (alldeps.mak): sort and uniq all results from this; duplicates
3341 hose gdb.tar.Z link building. Remove RCS files from
3342 tconfig and xconfig. Add config files for sun386. Add
3343 a few odd files to OTHERS and HFILES.
3345 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3347 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3348 Roll version number to 3.91.5. Make lint work in bindir.
3350 * README: Document cross-debugging and new file structure.
3352 * blockframe.c: Lint. Include "value.h" to declare read_register.
3353 (find_pc_partial_function): remove duplicate line.
3355 * command.h: Lint. Declare error_no_arg and dont_repeat.
3357 * tm-news.h: Remove inadvertently duplicated stuff.
3359 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3360 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3362 * config.gdb: Allow `config.gdb host target' form. Clean
3363 up previous change that printed bogus messages when you just said
3366 * core.c: #include "command.h" for lint.
3369 * main.c: Remove some casts of enums. Lint.
3376 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3378 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3379 read it from memory. This will allow us to save ptrace calls
3380 eventually. Changed caller single_step too.
3382 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3383 that we aren't going to use, saving many ptrace calls, especially
3384 when watchpointing or single stepping. Use some #define's for
3386 (store_inferior_registers): Ditto.
3387 (core_file_command): Use some #define's for constants.
3389 * tm-sparc.h: Add #define's for some register numbers, so we
3390 can eliminate the use of random constants in sparc-xdep.c.
3392 * stack.c (frame_command, print_frame_info, up_command,
3393 down_command) Remove frame_changed, since it
3394 causes a bug and doesn't seem to do anything useful. In some
3395 places it was used as a flag, in others as a stack level (?).
3397 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3398 default is to use the portable (vprintf) version rather than the
3400 * xm-news.h (MISSING_VPRINTF): Add.
3402 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3404 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3406 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3407 about linking debugged programs -Bstatic in the sun?os4 config
3408 files in tconfig and xconfig subdirectories.
3410 * main.c (main): Remove unreached exit(0) now that we exit
3413 * Create TODO file for online bug list. There are too many
3414 "little" bugs to keep track of on paper.
3416 * Change Projects file to refer to bug-gdb@cygnus.com
3417 rather than kingdon@ai.
3419 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3421 * Makefile.dist (VERSION): 3.91.4 now.
3423 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3424 (condense_misc_bunches): Add sanity check that misc_count is
3425 the same as the number of symbols in the bunch.
3427 * coffread.c: rename init_misc_bunches. Pass an argument
3428 to condense_misc_bunches (a zero).
3430 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3431 every time we are called; don't rely on our caller to do it.
3432 (add_file): Remove call to init_misc_bunches.
3434 * mipsread.c: Only warn, don't error, if unknown symbol types.
3435 This keeps an old gdb from falling on its face if it sees newly
3436 extended symbol info. Rename init_misc_bunches.
3438 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3440 * Merge in changes from Per Bothner for DECstations and other
3441 MIPS stuff. The rest is Bothner speaking:
3443 The next message is a merger of Alessando Forin's mips port with
3444 mine. I've tried to use my good if biased judgment to get
3445 the best of both. It *does* need testing.
3447 Some of the changes are general, *not* mips-specific.
3450 Didn't believe in little-endian bit order.
3451 There are still inconsistencies about whether flags
3452 like BITS_BIG_ENDIAN are integer (#if ...) or
3453 boolean (#ifdef ...). I tried to paper over them.
3455 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3456 Moved some misc_function code that was common to
3457 {dbx,coff,mips}read.c to symtab.c.
3458 In the process, I think I cleaned things up a bit.
3459 At the same time, moved obsavestring and obconcat to symtab.c.
3462 Removed obsolete condense_addl_misc_bunches (use
3463 condense_misc_bunches(1) instead).
3466 Needed to include <sys/dir>, at least on DECstations.
3468 valops.c, mips-tdep.c, tm-mips.h:
3469 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3470 conventions (when STACK_ALIGN is insufficient).
3471 Needed on mips, where doubles need 8-byte alignment,
3472 but ints only need 4.
3475 Removed cruft that was not being used.
3476 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3479 Print $ before register-names (I think that makes things a little
3481 Never print two instructions, even if one delays.
3482 Removed hex-disassemble set_cmd. (This is not mips-specific,
3483 so I think the argument is whether it is generally worthwhile or not.
3484 I'm inclined to think not, given how easy it is to
3485 convert between radixes in gdb.)
3488 This is basically Alessando's code.
3489 It doesn't use obstacks; I changed it to use obstacks
3490 in a few minor places where using malloc causes a
3491 memory leak. (Probably, more places could/should be changed.)
3492 I added record_misc_function where it was missing.
3493 In symbol_file_command and add_file_command, I tried
3494 to make the code consistent with more recent versions.
3495 Minor sylistic changes in parse_procedure.
3496 Make a .gdbinfo. psuedo-symbol point back to the real
3497 procedure symbol (using the isym field).
3500 This is basically from my port, but with a lot of details
3501 and a number of routines merged in from Alessando's version.
3502 I basically used my code "raw" backtrace (use heuristics
3503 from the actual code, rather than symbol table info) - though
3504 the idea is Alessandro's. I feel my code is a little cleaner
3505 here, particularly in being a little more flexible, such as being
3506 able to handle gcc-produced code (which it now can).
3507 It also doesn't do frame caching (which is not useful
3508 more recent gdb versions).
3509 I also used my code for push_/pop_dummy, more or less.
3510 I tried to incorporate AF's code for testing sigtramp
3511 while backtracing; I probably got it wrong.
3512 Added mips_print_register, which tries to scrunch as much
3513 information as possible on a screen...
3514 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3515 under mips-pinsn.c), I don't see anything mips-specific here,
3516 and I don't see it being all that useful anyway.
3519 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3520 Use more register names (rather than hard-cases numbers).
3522 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3524 * Hack up 3.90.11 changes:
3526 * Makefile.dist (depend): parameterize $(GCC).
3527 Add solib.c and solib.o.
3528 (readline): Fix vpath for both absolute or relative SRCDIR.
3530 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3531 Also, let the part I didn't understand at least compile so
3532 I can test the rest. FIXME.
3534 * dbxread.c: Fix thinko using strcmp.
3535 (init_psymbol_list): declare static.
3536 (partial_symbol_file_open): Comment cleanups better, avoid
3537 cleaning up the string table since the caller will do that.
3538 Move the stat for mod time into symbol_file_command, temporarily.
3539 (There should be a mod time for each symbol file, eventually,
3540 to control its rereading. FIXME.)
3542 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3543 SunOS, which gives error for shared libs otherwise. (From
3544 Schaefer, probably FIXME needs work for portability.)
3546 * solib.c: Move #include "param.h" to work.
3547 Lowercase all the Uppercase Letters In the Messages.
3548 (find_solib): Clean up inferior_so_name for debug printouts.
3549 Allow no argument, to mean all shared libraries.
3551 * symmisc.c: include param.h to get CLEAR_SOLIB.
3553 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3555 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
3556 to 3.90.11. ChangeLog entries below are from this.
3558 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3562 * Makefile.dist (HFILES): Add tm-sunos.h.
3564 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3568 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
3570 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
3572 * sparc-opcode.h Added single-operand version of rett.
3574 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3576 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
3577 Put parens around gcc_p in expansion.
3579 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3581 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
3583 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3585 * Changes for Sun shared libraries:
3586 blockframe.c (find_pc_partial_function): If a non-text symbol
3587 is found, set *address = pc - FUNCTION_START_OFFSET.
3588 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
3589 Disable breakpoints instead of giving an error.
3590 source.c (select_source_symtab): Initialize cs_pst.
3591 symmisc.c: Call CLEAR_SOLIB if defined.
3592 symtab.h: Make text{low,high} CORE_ADDR not int.
3593 (psymtab): New field addr.
3595 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
3596 (record_misc_function): Give correct type for N_DATA symbols.
3597 (condense_misc_bunches): do "misc_function_count = j" regardless
3599 Take code which is shared between symbol_file_command and
3600 add_file_command and put it into partial_symbol_file_{open,read}.
3601 Split add_file_command into add_file_command and add_file.
3602 Make psymtab_to_symtab read in the string table if the file
3604 Two new parameters to read_dbx_symtab and start_psymtab.
3605 tm-sunos.h: New file.
3607 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3609 * infcmd.c: Change cont_command to continue_command and "cont"
3612 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3614 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
3616 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
3618 * values.c (USE_STRUCT_CONVENTION): Check for structures of
3619 size 1,2,4,8 rather than size < 8.
3621 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
3622 as necessary, not just once.
3624 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3626 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3628 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3630 * tm-news.h: Add CALL_DUMMY_*.
3632 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
3634 * config.gdb: In list_host, list_target, use ${i}, not $i.
3636 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3638 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
3640 * sparc-opcode.h: Change all store floating-point state register
3641 instructions to have the right match & lose fields.
3643 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3645 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
3647 config.gdb: If srcdir != ., create readline directory and
3648 copy a makefile into it.
3650 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
3651 consistency with POSIX.
3653 * breakpoint.c (bpstat_stop_status): Disable watchpoint
3654 when we exit its exp_valid_block.
3656 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
3658 * Makefile.dist: Bump version to 3.91.3.
3660 * Clean up handling of breakpoint commands (somewhat).
3661 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3663 inferior.h: Add breakpoint_proceeded to inferior status struct
3664 and globals; save it and restore it.
3665 (clear_breakpoint_commands): Cleanup, remove old #define.
3667 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3668 (save_inferior_status, restore_inferior_status): handle it also.
3669 (proceed): Remove earlier code that set breakpoint_proceeded.
3670 It is now set only in clear_proceed_status.
3671 (clear_proceed_status): Cleanup, use bpstat_clear rather
3672 than clear_breakpoint_commands. No callers need the stop_bpstat
3673 between clear_proceed_status and proceed.
3675 infcmd.c: Add breakpoint_proceeded definition and comment.
3676 (cont_command, jump_command, signal_command): Move call to
3677 clear_proceed_status right next to call to proceed.
3679 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3680 caller's argument while running down the chain of breakpoints.
3681 Use new variable "breakpoint_proceeded" to determine when
3682 a command that it executes moves the inferior past the
3684 (bpstat_clear): Handle NULL argument.
3685 (bpstat_clear_actions): Avoid useless call to
3686 breakpoint_auto_delete.
3687 (delete_breakpoint): Clean up bpstat's that are pointing to
3688 the deleted breakpoint from the stop_bpstat chain.
3689 (breakpoint_auto_delete): Simplify.
3691 * Clean up handling of EOF, error on stdin, etc. This was
3692 prompted by a network problem that caused gdb to go into an
3693 infinite loop filling up its malloc'd memory.
3695 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
3696 not clear_breakpoints_commands, which is now gone.
3697 (main): If command_loop returns (e.g. from EOF on stdin), do
3698 a quit_command (looping back to command_loop if quit_command
3699 doesn't really quit).
3700 (command_loop): check result from command_line_input and
3701 exit if it returns NULL, rather than passing the NULL to
3703 (gdb_readline): Free malloc'd result space before returning
3706 * utils.c (query): Handle C-d to mean "yes", just as if the
3707 input was not a terminal. Also avoid infinite loop if EOF
3708 occurs in mid-input-line before newline. This allows
3709 query to be used at EOF on stdin with reasonable results.
3711 * infrun.c (proceed): Set breakpoint_proceeded.
3713 * values.c (value_as_long): Avoid infinite recursion for enums.
3714 (_initialize_values): Fix typo in help msg (kingdon).
3716 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
3717 RL_LIB for linking. This allows -lreadline for linking
3718 and nothing for dependencies, once readline is a real library.
3720 * config.gdb: Jim Kingdon: give useful error message if the
3721 host or target type is not recognized.
3723 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
3724 it just defines it. Dumb, but deal with it.
3726 * Jim Kingdon suggests:
3727 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
3729 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
3731 * Makefile.dist (VERSION): Bump version # to 3.91.2.
3733 * Clean up Bothner's changes.
3735 * blockframe.c (clear_pc_function_cache): New function.
3736 * blockframe.c: remake cache_pc_function_* static.
3737 * dbxread.c (symbol_file_command): remove references to
3738 cache_pc_function_* variables.
3739 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
3740 * printcmd.c: Avoid kludging a global variable (addressprint)
3741 to avoid printing the address of a string twice. Instead,
3742 pass the format letter 's' down low enough that it can be seen
3743 to avoid this problem.
3744 (print_formatted): Pass format arg to value_print.
3745 (restore_addressprint): Remove function.
3746 (do_examine): Avoid hacking addressprint, cleanups and such.
3747 (print_frame_args): Add a comment to a Bothner change.
3748 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
3749 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
3750 to wipe out the values cached in blockframe.c.
3751 * symtab.c (find_method): Add comment saying how big you must
3752 allocate to be "big enough". Per being terse again.
3753 * valprint.c (val_print): Handle format letter "s" to print
3754 strings without addresses. Add comment to vtbl printing code
3755 which casts with wild abandon. Rearrange reference-printing
3757 @0xaddr: value (print w/addressprint)
3758 value (print w/~addressprint)
3759 @0xaddr (parameter lists w/addressprint)
3760 or nothing (parameter lists w/o addressprint)
3762 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
3764 * Merge more changes from Per Bothner:
3766 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
3767 annoying) that I tried to improve it. Here are my suggestions.
3769 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
3772 Do automatic de-reference when taking the address of a reference.
3774 Don't deref_ref when printing parameter lists.
3776 More attempts at treating refernences properly.
3778 In val_print, if deref_ref==0, don't print dangling " = ".
3780 Add COERCE_REF macro, which de-references an REF.
3782 * Merge changes from Per Bothner:
3784 * Fixed (Sony news)-specific configuration problems.
3785 * Fixed other problems with using vanilla pcc and libc (enum problems;
3786 assumption that vsprintf exists).
3787 * Some major speed-ups (finc_pc_partial_function now caches a match;
3788 parsing avoids duplicate symbol_lookup calls).
3789 * Changed handling of baseclasses (no longer use baseclasses field
3790 of struct type, use the first n_baseclasses fields instead).
3791 * Various minor changes/fixes, most C++-related.
3794 Cache the most previous match from find_pc_partial_function.
3795 (Save both low and high ends of matching function's pc range.)
3796 This speeds up the loop of infrun.c:wait_for_inferior quite
3797 a bit, and makes step/next commands much zippier.
3799 Added an enum->int cast (otherwise, some compilers barf).
3801 No longer set baseclass offset to 0, since multiple
3802 inheritance now mostly works.
3803 Added a number of casts, to shut up compiler warnings
3804 (after stabs where made enums, not ints).
3805 When discarding a symbol table (in symbol_file_command),
3806 must clear the cache introduced in blockframe.c.
3807 Don't convert $vtbl_ptr_type to vtbl any more.
3808 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
3809 Mask off sign bit emitted by g++ for virtual table offset.
3810 Set voffset to -1 (not 1) for static member functions.
3812 Changed parsing/lexing of names to avoid doing symbol lookup twice
3813 (once when lexing to determine symbol class, once for real).
3814 Now only call symbol_lookup once. Fields of 'this' win especially big.
3816 Subpress printing addr twice in the case of 'x/s addr'.
3818 lookup_basetype_type is no longer used.
3819 Add find_methods as recursive helper function to decode_line_1.
3820 This allows multiple inheritance to work.
3821 Also, once one or more matches has been found, do not look in
3822 base-classes. (Baseclass methods would be overridden, anyway.)
3824 Removed baseclasses array in struct type.
3825 Instead of using baseclasses[i], use fields[i-1].
3826 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
3827 Changed sign convention of voffset (previous was inconsistent).
3829 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
3831 Used to assume existence of vsprintf. Re-written to not need it
3832 if HAVE_VPRINTF is undefined.
3834 typecmp was too pessimistic. Made it less so.
3836 Don't print space after address.
3837 If vtable points to a misc symbol (with 0 offset), print it,
3838 since that indicates the actual class of the object.
3839 Changed ype_print_derivation_info to use new inheritance
3840 scheme (without baseclasses vector).
3842 In value_primitive_field, fixed some bugs left over from previous set of fixes.
3843 Also, changes needed because TYPE_BASECLASSES were removed.
3845 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
3847 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
3850 If there is no path set, and the symbols don't indicate what directory
3851 a file was compiled in, look in the current directory. But either
3852 a path or a known compilation directory will prevent this.
3855 Three independent bug fixes:
3856 * Remove the #if 0 block that breaks some stuff.
3857 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
3858 adapt gdb to either SunOS 4.0.* or 4.1.
3859 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
3862 Instantiate the class T when looking for methods in it. (Tiemann@sun)
3865 (type_print) Demangle the name being printed.
3866 (type_print_base) Handle botched demangling without coredump (tiemann).
3869 (check_stub_method): Document routine.
3870 (tiemann) fix bug for no-arg functions
3871 Avoid clobbering beyond end of malloc'd storage.
3872 Terminate the argument list properly.
3874 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
3876 * Changes merged by John Gilmore:
3879 In breakpoint_1, use new print_address_symbolic instead
3880 of find_pc_partial_function. (This forces use of assembler-level
3881 addresses, and avoids misleading non-mangled source-level names.)
3883 Generalize ansi argument such that -1 means skip arglist totally.
3884 Removed global variable print_ansi_qualifiers (which made
3885 code non-reentrant), in favor of extra explicit arguments
3886 to internal routines.
3888 Add new helper function print_address_symbolic.
3889 Use find_pc_misc_function instead of find_pc_partial_function
3890 (since we want assembler-level symbols here).
3892 Print unknown function as just "f (...)", not "f (...) (...)".
3893 Use new fputs_demangled explicitly.
3895 Fixed a typing violation (problem: value.h cannot be imported
3896 without renaming many variable in this file).
3897 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
3898 decode_line_1: Moved forward some never-reached code.
3899 Made decode_line_2 skip function prologues correctly.
3901 fputs_filtered should not demangle by default.
3902 Add new fputs_demangled to demangle on demand..
3904 Change value_struct_elt to use value_primitive_field (using recursive
3905 utility function search_struct_field). This allows foo.bar to work
3906 for multiple inheritance (so far only for data fields).
3907 Change check_field in the same way (recursive helper function
3908 to support multiple inheritance).
3909 (Note: there are more of these problems that I haven't fixed.
3910 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
3911 value_of_this: 'this' symbol name is now just "this", note "$this".
3913 Don't print static members.
3914 Avoid printing "members of <type>" if there are none.
3915 Simplified type_print_derivation_info by merging duplicate code.
3916 Remove useless blank lines in type_print_base (ptype command).
3918 Added declaration of new routine value_primitive_field.
3920 Added value_primitive_field which is generalized version of
3921 value_field that can handle multiple inheritance (non-zero offsets etc).
3922 Re-implemented value_field to call value_primitive_field.
3924 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
3926 * infcmd.c -- insert else to avoid 'delete env' coredump when you
3927 delete the whole environment. Karl Berry reported the bug.
3928 * source.c - fix openp to avoid //'s in filenames, which
3929 trigger an Emacs bug causing it to not be able to find files
3930 when running gdb in a window.
3931 * dbxread.c - zap the #if 0 that botches the add-file code.
3932 It seems to work a lot better without all the code commented out.
3934 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
3936 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
3939 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
3941 * Makefile - added a ${CFLAGS} to a couple of entries,
3942 added remote-sa.sparc.c
3943 * added remote.sa-sparc.c, a modification of remote.c
3944 which conducts a dialog directly with the SparcStation prom.
3945 * breakpoint.c, infrun.c, sparcdep.c added
3946 remote_insert_breakpoint(), and remote_remove_breakpoint()
3947 to breakpoint.c instead of directly writing breakpoint instructions.
3948 * sparcdep.c on remote_debugging,there is no need
3949 to remove signle step breakpoint instructions.
3950 * main.c added "-epoch" flag and "int epoch_interface" to main.c
3952 * printcmd.c - epoch interface sends lisp expressions to open up
3953 epoch windows on inspection.
3954 * valprint.c - added arrayprint, and addressprint and made adding
3955 format controls easier
3956 * wait.h added a couple of undef's because we were getting
3957 complaints about WSTOPSIG and WTERMSIG begin redefined.
3960 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
3962 * symtab.c (decode_line_1): Add support for handling method stubs
3963 in the type information.
3965 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
3967 * values.c (baseclass_addr): Run loop from INDEX+1 to
3968 N_BASECLASSES; otherwise, we can still get into a loop.
3969 @@ This should be restructured to use a cleaner search strategy.
3971 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
3973 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
3974 abbreviation "Tt" for tags which have the same name as their
3977 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
3979 * symtab.c (list_symbols): add ability to set breakpoints on all
3980 the functions which match a particular regular expression.
3982 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
3984 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
3985 should print ANSI qualifiers (such as `const' and `volatile').
3986 All callers changed to call with ANSI == 1, except from
3987 `check_method_stub', which uses old-style syntax.
3989 * symseg.h (struct fn_field): Remove unneccessary `args' field.
3990 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
3992 * values.c (check_stub_method): New function.
3994 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
3996 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
3997 * valprint (type_print_base): Ditto.
3999 * symtab.c (gdb_mangle_typename): New function.
4001 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
4003 * breakpoint.c (catch_command): New function. Provides a
4004 mechanism to set breakpoints based on catch clauses.
4005 (disable_catch): Similar, but disables breakpoints on catch
4007 (delete_catch): Similar, but deleted breakpoints on catch clauses.
4009 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
4011 * blockframe.c (blockvector_for_pc): New function.
4012 * blockframe.c (block_for_pc): Changed to call
4013 `blockvector_for_pc' and get the block itself.
4015 * stack.c (catch_info): New function. Prints info about
4016 exceptions which can be caught in the current frame.
4017 * stack.c (print_frame_label_vars): New function. Similar to
4018 `print_frame_local_vars'.
4019 * stack.c (print_block_frame_labels): Prints out labels that are
