1 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
3 * Partial update to README (which still needs work for this
4 release!): (1) use of configure corrected for new script,
5 (2) "make gdb.dvi" and "make gdb.info" mentioned.
7 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
9 * symtab.c (lookup_symbol): Don't complain right off about
10 no debug symbols; use the misc function vector first.
11 (list_symbols): Use misc function vector to find symbols
12 that don't have debug info, and print them.
13 (find_pc_symtab): Temporarily avoid fatal() when psymtab
14 PC range doesn't match symtab PC range, as it does on the
15 MIPS because our symtab reading isn't perfect.
17 * dbxread.c (dbx_symfile_read): Make warning about
18 "no debug symbols" slightly nicer.
20 * source.c (select_source_symtab): If "main" symbol exists,
21 but decode_line_spec can't find line info, don't just return
22 a zero; try other source symtabs or give an error.
24 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
25 their low addresses first, then rip through fixing high addrs.
27 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
29 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
31 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
33 * Minor, mostly mechanical, cleanup of doc subdir for clean
34 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
35 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
37 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
39 Mostly MIPS and general symbol-reading fixups.
41 * doc/gdbint.texinfo: Add documentation on symbol-reading
44 * mipsread.c: Remove kludges around #include "ecoff.h".
45 Remove redefinitions of a_magic, etc, no longer used.
46 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
47 Fix global overview comments to match symfile.c protocol.
48 (mipscoff_new_init): Eliminate cur_hdr if we have one.
49 (mipscoff_symfile_read): Eliminate unused code. Avoid
50 sorting all the symtabs, when all we have read here is psymtabs.
51 The symtabs are sorted as they are created anyway. Tell
52 condense_misc_bunches whether we're mainline.
53 (psymtab_to_symtab_1): Pass filename when recursing, to make
54 stack trace more informative.
55 (parse_partial_symbols): Assume cur_hdr as argument.
56 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
57 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
58 the TYPE_NAME of char *, since that's done in symfile.c.
59 (free_numargs, parse_symbol, add_symbol, add_block,
60 shrink_linetable): Declare these fns void.
61 (upgrade_type): Convert tree of if's to switch. Clean up
62 bogus "off == 0" handling with a complaint. Avoid setting
63 field bitpos and bitsize of array with lower and upper bounds.
64 Check specified bitsize of elements against their actual type's
65 bitsize, and complain if different. Complain about unknown
67 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
68 (psymtab_to_symtab_1): Print names of subsidiary files that
69 are being read in. FIXME, we read far too many files. This code
70 is not the problem, the problem is in parse_fdr where the psymtabs
72 (cross_ref): Result should indicate that we used one aux entry
73 normally, or two if we encountered a "next" entry. This used
74 to leave the caller pointing at the wrong aux entry.
75 (add_symbol): If overflowed cur_block, reallocate it larger,
76 chase all pointers to it, and complain(), rather than clobber memory.
77 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
78 (new_field): Only allocate one field initially, not two.
79 Pull ++ out of macro argument. Simplify.
80 (_initialize_mipsread): Avoid initialization of importd
81 global_psymbols and static_psymbols.
83 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
84 to properly set pst->symtab; avoid searching for it.
85 (symfile_fns): Improve comments, add a FIXME.
86 * dbxread.c: Update comments to reflect symfile protocol.
87 (read_ofile_symtab, end_symtab): Return the symtab.
88 (psymtab_to_symtab_1): Set pst->symtab.
90 * coffread.c (coff_symfile_read): tell condense_misc_bunches
91 whether we're mainline.
93 * symfile.h (sym_fns): Remove unused sym_discard member.
94 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
96 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
97 the environment variable is not.
98 * infcmd.c (finish_command): Use filtered printfs.
99 * cplus-dem.c: Add struct tags to a few unnamed structs.
100 * valops.c (value_coerce_array): Improve comments.
101 * valprint.c (type_print_varspec_suffix): Print array size only
102 if greater than zero.
103 * m88k-tdep.c: Shift some lines left by one space, that had
104 apparently been trashed at some point.
105 * TODO: More things to do, a few got done.
107 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
109 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
110 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
112 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
113 * expread.y, findvar.c, symmisc.c: Ditto.
114 * printcmd.c (address_info): Update printed forms of LOC_
115 symbols. Elim LOC_EXTERNAL.
116 (print_frame_args): Keep track of param stack offsets before
117 re-looking up to find the local register param is kept in.
119 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
120 Further integration of mipsread into gdb. Eliminate unused
121 routines, duplicate declarations. Handle static symbols in
122 psymtabs as well as external symbols. When reading symtabs,
123 insert symbols into the correct block (global, static, or a local
125 (read_mips_symtab, parse_partial_symbols): Don't pass useless
127 (mipscoff_symfile_read): Don't call select_source_symtab.
128 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
129 rather than SYMBOL_VALUE.
130 (parse_external): Comment clobbering of top_stack.
131 (parse_partial_symbols): Update comments. Allocate and parse
132 static symbols as well as external symbols. FIXME, enum values
133 are not handled in this pass, but should be. Inline new_psymbol.
134 Use SYMBOL_VALUE_ADDRESS.
135 (psymtab_to_symtab_1): Read symbols into global static block
136 by default (until enter some function's local block context).
137 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
138 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
140 * source.c (select_source_symtab): Select a source symtab
141 from either the symtabs or, failing that, the psymtabs.
142 (list_command): Update error message.
143 (forward_search_command, reverse_search_command): Use getc, not
144 fgetc, for speed. FIXME, add comment about buffers that die if
145 overrun by long line.
147 * values.c (unpack_field_as_long, modify_field): Avoid shifting
148 by an entire word, which is not portable, if we have a 32-bit
149 field. (Code in dbxread.c already turns such bitfields, if
150 aligned, into ordinary ints, but fixing this will help for other
151 symbol formats and for future changes.)
152 * core.c (core_open): Handle ANSI const brain death.
153 * utils.c (vprintf): Fix varargs typo.
155 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
157 * findvar.c (find_var_value): Handle &function better.
158 * TODO: Document work needed on &fn and &array.
159 * printcmd.c (print_address_symbolic): New arg is the prefix
160 to print if a name is printed.
161 (print_address_demangle): Honor "set print address" now.
162 Use new arg above to improve spacing of output.
163 * valprint.c (val_print): When printing function pointers,
164 print symbolic form too.
165 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
167 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
169 * core.c (memory_error): Reword error msg to mislead less.
171 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
173 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
174 parse_partial_symbols): Use newer BFD internals (external_filehdr
175 and external_aouthdr), byte-swap the fields that we care about
176 before using them, and make the file header data local to
177 read_the_mips_symtab rather than global.
179 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
181 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
182 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
184 * main.c (command_line_input): Flush stdout and stderr
185 before every call to readline. This reportedly fixes a bug
186 that comes up in Sys V running emacs-gdb and/or xxgdb,
187 when stdin/out are pipes or sockets.
189 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
191 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
192 Avoid declaring Makefile dependencies, because GNU Make stupidly
193 tries to update it if we do.
195 * coffread.c: Revise for minor changes to bfd internal coff
198 * configure: If -template= is given a relative path, make it
199 absolute before recurring in subdirectories.
201 * configure, configure.in, Makefile.in: Install "configure" script
202 as replacement for config.gdb.
203 * config.gdb, Makefile.dist, Makefile.sdir: Remove
204 * README: Update for configure, mostly. FIXME.
206 * Add dec3100 as equivalent to littlemips. Indicate in all host &
207 target config files that they are for the host. When the lines
208 get copied into the Makefile, this makes it more obvious what's
211 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
213 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
214 tabs, which end up in the disassembler output inadvertently.
216 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
218 Make it compile cleanly in an ANSI GCC2 environment.
220 * blockframe.c: <stdio.h>
221 * cplus-dem.c: free takes a void *, ifdef __STDC__
222 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
224 * defs.h (alloca): Avoid doing anything if alloca already def'd.
225 * stddef.h, stdlib.h: Remove these files.
226 * symtab.c: Avoid declaring qsort, close.
227 * symfile.c: Avoid declaring close.
228 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
229 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
231 Assorted other changes.
232 * dbxread.c: include "libaout.h", not "liba.out.h".
233 * printcmd.c (print_frame_args): Set recurse properly for
234 indentation of struct and array parameters.
235 * valops.c (value_cast): Allow cast to void.
236 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
237 single_step() in a target-independent fashion.
238 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
239 set up to be ready to continue. This makes us target independent.
240 * infptrace.c (child_resume): Remove call to single_step; now
241 can single step a SPARC target of any kind.
243 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
245 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
246 docn into separate sections---basically chapters, plus two loose
247 pieces that can be configured to go in different places. This
248 allows GNU m4 to preprocess the manual without coredumping.
250 * Makefile.dist: tell TeX where to find texinfo.
252 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
254 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
255 the new target "rdl-apps.texinfo" which captures the Makefile
256 variable that records where to find the Readline libraries.
258 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
260 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
261 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
262 * defs.h (const, volatile): Only define if not already defined.
263 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
265 * README: Update for release 3.95.
266 * config.gdb: Don't create readline dir in subdir builds.
267 * main.c: Include with "..." form for non-system include files,
268 so "gcc -MM" for "make depend" works.
269 Include readline files with "...h" rather than <readline/...h>.
270 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
272 * coffread.c: Undo minor damage done by Rich Pixley. Use
273 different internal and external representations of COFF
274 data structures. Use new BFD routines for swapping them in and
276 * symfile.c (free_named_symtabs): Avoid freeing file names that
277 are null or empty. Old i960 tools seem to produce files that
278 claim to have empty names, causing each successive file read
279 to blow away the previous one.
280 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
281 Move deferred_stores to top of file, but don't separate its
282 #define's from its variable. Add commentary.
283 * Makefile.dist: Fix Rich damage; undo "configure" changes in
284 favor of keeping the (working) config.gdb. Move readline
287 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
289 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
291 * infptrace.c (fetch_registers): no result, since now void.
292 * tconfig/news: target depends on m68k-tdep too.
294 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
296 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
299 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
300 applied various small fixes due to or inspired by RMS comments
302 * doc/gdb.texinfo: finished using all RMS comments, save those for
303 appendices on readline and cmd history (which are in other source
306 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
308 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
309 chapter 9; (2) documented 'break' command's menu mode for
310 overloaded names, in response to hgs problem report C++ p-31
312 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
314 * doc/gdb.texinfo: (1) better introductory example; (2) more
315 consistent use of @code, @samp, @file, @kbd throughout; small
316 cleanups to first three nodes; (3) new "Contributors" node;
317 (4) Appendix, Renamed Commands; (5) divert specialized startup
318 instructions to "Targets" chapter for generic manuals, while
319 leaving them up front for manuals specific to specialized
320 environments; (6) apply fixes from RMS comments through chapter 4.
322 * pretex.m4: modify explanatory text slightly (and redefine
323 "regexp") to keep GNU m4 from complaining. (It still crashes
324 later, but one step at a time...)
326 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
328 * readline/readline.c (update_line): Avoid dereferencing a pointer
329 before comparing it to its bounds. Saber caught this.
330 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
331 and only set PC if tgetstr returned non-null. Saber caught this.
333 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
335 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
336 stuff for config manual) here where it counts; updated
337 to use new subdir structure (gdb/doc/).
339 * Makefile: generated from above via
343 * gdbint.texinfo: added instructions on generating gdb.info* files
344 locally for release. These are ordinary info
345 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
346 Makefile)---but due to use of texinfo 2, can't count on makeinfo
347 to generate these, so we distribute them already formatted.
349 * gdb.texinfo: included full Info node and menu crud (as generated
350 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
352 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
353 put in comments-for-future gdb.info target (one day makeinfo will
356 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
358 * gdb.texinfo: Updated to include new or old undocumented
359 commands, at least the following (perhaps some others I forgot to
360 record): info f, info float, info path, info program, info s, info
361 set, info source, info terminal, info types, info user, set/show
363 Also covered all recent GDB command renames for v4.
365 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
367 * mipsread.c: Rather than keeping count of how many symtabs
368 and psymtabs we have, for sorting purposes, count them when
369 we need to sort. This fixes bug in rereading of symbol tables.
371 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
373 * infcmd.c: renamed "info path" to "show paths"
374 * gdbrc.tex: documented above.
376 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
378 * remote.c: Fix comments.
379 * utils.c (error): Force out any pending wrap output.
381 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
383 * Makefile.dist: Roll VERSION to 3.95.
384 Fix up "saber_gdb" to work again.
385 * saber.suppress: Update.
387 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
388 symtab.h, target.c, target.h: Lint.
389 * core.c: setup and select frame after reading shared libs,
390 else reading shared libs will clobber them. Lint.
391 * utils.c (error): Force out any buffered wrap text.
393 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
395 * remote.c: Remove decls of memory_insert_breakpoint
396 and memory_remove_breakpoint, no longer used. (Suggestion of
399 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
400 to make it easier to interface to "configure"'d libraries.
402 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
404 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
405 aliases for set/show print.
407 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

447 * {x,t}config/m88k ({X,T}DEPFILES): Add missing files.
449 * mtrace.c: Don't typedef things like size_t, just #define them.
451 * coffread.c [TDESC]: #if 0 out references to coffsyn.
453 * symtab.h (struct symtab): Include EXTRA_SYMTAB_INFO.
454 tm-88k.h: Define EXTRA_SYMTAB_INFO.
456 * coffread.c [TDESC]: Include "tdesc.h" and make tdesc_handle
457 dc_dcontext_t not int.
459 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
461 * coffread.c [TDESC]: Move setting of debug_info from
462 coff_symfile_read to find_linenos and make it work with BFD.
464 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
466 * signame.c: Cast const char* to char* when assigning to sys_siglist.
468 * utils.c (strsave): Make arg const char* not char*.
470 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use
471 bpstat_explains_signal (stop_bpstat) not stop_breakpoint.
473 * tm-88k.h (START_INFERIOR_HOOK): Make tdesc_handle a dc_handle_t.
475 * tm-88k.h (EXTRACT_RETURN_VALUE): Use char * not void *.
477 * findvar.c (read_var_value, case LOC_CONST_BYTES): Put the address
478 in a char *, not a CORE_ADDR. Use SYMBOL_VALUE_BYTES.

491 Mips bringup and general cleanup
493 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
494 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
495 (This still doesn't seem to make MIPS bkpts work.)
496 * mipsread.c: Remove dup "Reading symbol data..." msg.
497 (symbol_file_command, add_file_command): Remove, obsol.
498 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
499 Wrap output appropriately.
500 * stack.c (locals_info, catch_info, args_info): Check

987 (_initialize_symtab): Restore "info types".
989 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
991 * m68k-stub.c: Remote stub for 680x0's, created from
992 rem-m68k.shar (which is removed).
993 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
994 Remove RCS log stuff now that we use CVS and it blows our diffs.
996 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
998 * symmisc.c (free_named_symtab): Make it work, in its current
999 kludgy fashion. Change result to indicate if we blew away bkpts.
1000 * dbxread.c (end_symtab): Accumulate result from
1001 free_named_symtab and print warning if we blew user's state.
1002 * symfile.h: free_named_symtab now returns an int.
1004 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1006 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
1007 is the first symbol read, even if not mainline.
1008 (dbx_psymtab_to_symtab): symfile might be zero, cope.
1009 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1010 (set_section_command): New command ("section xxx yyy" -- should
1011 be renamed to "set section xxx yyy" FIXME) which sets the
1012 base address of a section of the exec file, overriding the
1013 virtual address that BFD reports.
1015 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1017 * exec.c: Add add_syms_addr_command to exec_ops, so you can
1018 load symbols at any address while examining an exec file.
1020 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1022 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1023 for printing the float info is host-dependent, not
1024 target-dependent. FIXME.
1025 * i386-pinsn.c: Move #includes to top, remove useless ones.
1026 * i386-tdep.c: Don't bother including <.../reg.h> since we
1027 don't use it (and it doesn't exist on host systems).
1029 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1030 Convert negative numbers properly.
1031 (ieee_test): Make numbers really random; fix format arg.
1033 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1034 * core.c (core_detach): Unpush core_ops, which might not be on
1035 top. We used to just pop the top, which broke things. Don't
1036 need dont_repeat() any more.
1037 (core_file_command): Psst! Don't repeat it.
1038 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1039 * expprint.c (print_subexp): Avoid switch fallthru on
1040 BINOP_ASSIGN_MODIFY, so we can print += and such.
1041 * frame.h: Fix typo.
1042 * inflow.c (kill_command): After killing inferior, print our
1043 current frame in the core file, if we have one.
1044 (generic_mourn_inferior): When inferior dies, either select
1045 the current frame (in the new target, e.g. core file), or
1046 set both the current and selected frames to NULL.
1048 Changes from Peter Schauer.
1050 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1052 * Make all file names fit in 14 characters (sigh and damn!):
1053 mv hp300hpux-xdep.c hp300ux-xdep.c
1054 mv symmetry-xdep.c symm-xdep.c
1055 mv symmetry-tdep.c symm-tdep.c
1056 mv convex-opcode.h convx-opcode.h
1057 mv tm-vxworks960.h tm-vx960.h
1058 mv tm-vxworks68.h tm-vx68.h
1059 mv Makefile.srcdir Makefile.sdir
1060 mv gdb-int.texinfo gdbint.texinfo
1061 mv remote-sa.m68k.shar rem-m68k.shar
1062 mv remote-multi.shar rem-multi.shar
1063 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1064 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1065 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1068 * command.c (user_info_1, user_info): New command for listing
1069 the user-defined commands.
1071 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1073 * dbxread.c (really_free_pendings): Clear file_symbols
1074 and global_symbols after freeing them; otherwise, running
1075 this function twice (if it appears twice on the cleanup
1076 chain), we try to free things twice.
1078 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1079 based on text_addr (the address of text in core), not on addr (the
1080 offset between text in the .o file and in core). This change
1081 is from Peter Schauer.
1083 * main.c: Define ALL_CLEANUPS as a cast of zero.
1084 (return_to_top_level): Use it.
1085 (main): Do all cleanups after each command run as part
1086 of the gdb startup sequence. Also do all cleanups before
1087 entering the command loop, and every time we exit the command
1088 loop and reenter. Before, the cleanups from the startup sequence
1089 were being left undone until the first error!
1090 (command_loop): Rename do_nothing cleanup to command_loop_marker
1091 so we can see it easily when examining the cleanup chain.
1092 (init_signals): Add another do_nothing for signal handling.
1093 (quit_command): Only try to kill target if it has execution.
1094 Problems in the target stack got us into a state where
1095 inferior_pid was nonzero but none of the targets had execution.
1096 In this state you couldn't exit gdb.
1098 * dbxread.c: Two changes from Peter Schauer.
1099 (echo_command): Fflush output after an echo command.
1100 (show_history): Pass all args to cmd_show_list.
1102 * utils.c (init_malloc): Call mtrace to turn on tracing
1103 if the environment variable MALLOC_TRACE is set to a file name.
1104 * mtrace.c: Add source file which provides a log of every malloc,
1105 free, and realloc to a trace file.
1106 * mtrace.awk: Add source file which analyzes the trace file.
1107 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1108 (VERSION): Roll to 3.94.3.
1110 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1111 (check_duplicates): Don't bother with watchpoints.
1112 (set_raw_breakpoint): Comment about danger of this routine.
1113 (watch_command): Parse and eval all args before calling
1116 * solib.c (find_solib): Avoid error in referencing memory to
1117 see if any more shared libraries have been added. This is
1118 particularly useful if the target has terminated. Bug reported
1121 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1122 in bringing up 3.94.2 on the Sun-3.
1124 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1125 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1126 expression (in scope) before reenabling watchpoint.
1127 * signame.c (init_sigs): Add missing declaration of i, fix
1128 sys_siglist declaration.
1129 * source.c (list_command): Fixed range computation to use
1131 * stack.c (backtrace_command): Do not allow command if target has
1132 no stack, print informative error message.
1133 * target.c (target_command): Do not write into command line
1134 because this fails if the target command is used in a user defined
1135 command. [This change was enhanced by gnu to support any-
1136 unique-prefix matching on target names.]
1137 * valops.c (value_struct_elt): Avoid infinite loop on an
1138 erroneous attempt to print the member of function (try p main.p).
1140 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1142 * expread.y (name_no_typename): Avoid reduce/reduce errors
1143 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1144 Since the GDB parser really doesn't use name_no_typename in a
1145 name-only context, the parser can't tell the diff between
1146 names and numbers here. Avoid allowing a name_no_typename
1147 to be a NAME_OR_*INT to resolve the conflict.
1149 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1151 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1153 * valprint.c (val_print_fields): bitfield printing didn't handle
1154 byte order. Indirect through a few more fns to cope.
1156 * values.c (modify_field): also cope with byte order.
1158 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1160 Cleanup for release 3.94.2:
1162 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1163 include files. Roll version to 3.94.2.
1165 * coffread.c (init_stringtab): Read length into unsigned char
1166 array before swapping; don't assume 32-bit longs.
1168 * target.c (target_info): Don't bother with get_sym_file, just use
1169 the symfile global variable.
1170 * symtab.h, symfile.c (get_sym_file): Delete it.
1172 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1173 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1174 (read_type): Replace one more error() with complain().
1176 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1178 * i960-tdep.c: Fix copyright attribution.
1180 * config.gdb: Quote all backquotes in doublequotes. You can
1181 quote me on that. BSD 4.4 shell found this one.
1183 * infptrace.c (throughout): The third argument to ptrace is an
1186 * infrun.c (wait_for_inferior): When program has terminated, we
1187 have to call target_terminal_ours before we pop that target off
1188 the stack (e.g. before a call to target_kill or
1189 target_mourn_inferior). This fixes problem where a program
1190 terminates, then GDB stops for (tty output) and you have to type
1191 "fg" to the shell to resume it. FIXME: This code for what to
1192 do after termination really should be in normal_stop instead.
1194 * gdbcore.h (read_memory_check): Change declaration; it changed
1197 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1198 4.4 prereleases, this avoids a bug in their sgtty compatability
1200 * remote.c: Use terminal.h rather than hand-rolling the same.
1202 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1203 * utils.c (strsave, strstr): Fix arg types.
1204 * valprint.c (val_print): lint
1206 MIPS symbol table support from Per Bothner:
1208 * symfile.c (symtab_fns): Remove initializer table that needs to
1209 be hacked for each new symbol file format supported.
1210 (add_symtab_fns): New function, chains symbol table
1211 handlers into the global list.
1212 (symfile_init): Search this list.
1213 * symfile.h: Add next pointer, declare add_symtab_fns.
1214 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1215 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1217 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1218 symbol *). Thus, we no longer need the hack to trash
1219 pst->filename. Good, since that hack confused code in symfile.c!
1221 (reorder_symtabs, destroy_all_symtabs): Removed static
1222 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1223 Instead, the latter now uses a temporary array (stack-allocated
1224 from an obstack, and then freed).
1226 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1227 haven't been set in the outermost stBlock of a procedure. This was
1228 a problem with f77 binaries on Ultrix 4.?.
1230 (new_symtab, new_symbol, new_type): Continue changing code to use
1231 obstacks more and otherwise conform to dbxread internal style.
1232 Made the free_code of symtabs be free_linetable (as in dbxread)
1233 instead of free_contents. This implies memory leaks when reading
1234 a new symbol table, until the conversion is finished. Did change
1235 (struct symbol) and (struct type) to be allocated on the
1236 symbol_obstack. Blocks and blockvectors are among the things
1239 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1240 tested much, but it solved one problem (reported by Meissner), and
1241 cleans up some other things. The problem happened when an
1242 included file contains actual code (functions) and not just
1243 definitions. The mips coff is a little inconvenient there, since
1244 it may cause a procedure to be mapped to the wrong psymtab.
1246 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1247 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1248 this will need work for the new core paradigm.
1250 Opcode patches from the net:
1252 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1253 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1254 missing altogether - they are added here. From Bruce Bauman.
1255 * mips-opcode.h: The low mask for C0 instructions was too small.
1256 From Garrett Lau. I modified the fix to check the entire 32-bit
1259 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1262 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1264 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1266 * dbxread.c (read_type): Pointer subtraction (value_sub in
1267 valarith.c) sometimes failed because the types of the
1268 pointers being subtracted were not identical.
1269 These differed because dbxread.c was allocating pointer types
1270 using dbx_alloc_type+smash_to_pointer_type instead of
1271 lookup_pointer_type. I failed to find a justification for the
1272 former, so I changed it to use the latter. Similarly, I
1273 replaced smash_to_function_type by lookup_function_type,
1274 and smash_to_reference_type by lookup_reference_type.
1276 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1277 _initialize_mipsread): corresponding changes.
1279 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1281 * source.c (mod_path): Do tilde_expand on each component of the path,
1282 rather than on the (list of) paths as a whole.
1283 (print_source_lines): Set first_line_listed in addition to
1284 current_source_symtab and current_source_line. If the source was
1285 not findable, after a "dir" command to fix the problem,
1286 a "list" would get the wrong lines.
1288 While I was there... (gnu):
1290 * dbxread.c (read_type): Change error to complaint.
1292 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1294 First attempt at detailed understanding of symbol table memory alloc.
1296 * dbxread.c (dbx_symfile_read): Free our string table if we
1297 aren't the mainline. Free the "info" struct since we're done with
1299 (init_psymbol_list): Free any previously allocated psymbol lists.
1300 (): FIXME: Should realloc-down the psymbol lists when done reading
1301 the main symbol file?
1303 * symmisc.c (free_symtab): Free fullname field too.
1305 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1306 (REGISTER_ADDR): Make result type unsigned int.
1308 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1309 define REGEX must also define REGEX1 (its dependency).
1311 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1313 * tconfig/i960: No longer works, points you at vxworks960 or
1316 * xgdb.c, XGDB-README: Remove file. Users can get the much
1318 * Makefile.dist: Remove all trace of xgdb.
1320 * breakpoint.c (breakpoint_1): Pass demangle arg to
1321 print_address_symbolic.
1322 (clear_breakpoints): Remove unused function.
1323 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1324 (breakpoint_re_set): Use catch_errors to do them all anyway.
1326 * gdb-int.texinfo (Host versus Target): Add section on what is
1327 a "host" feature versus what is a "target" feature.
1329 * infcmd.c (path_command, path_info): Handle the PATH variable
1330 (object search path) as conveniently as the source search path.
1331 * environ.c (set_in_environ): Set some vars in GDB's environment,
1332 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1333 * source.c (mod_path): New function, from guts of
1334 directory_command, modifies a path. Used by path_command.
1335 (directory_command): Call it.
1336 * defs.h (strsave): Declare.
1338 * utils.c (sevenbit_strings): Add new printing option.
1339 (printchar): Use it.
1340 (strsave): Provide this handy helper routine.
1341 (set_width_command): Rename set_screen_width_command.
1342 (_initialize_utils): "set screen-width" => "set width";
1343 "set screen-height" => "set height"; add sevenbit-strings.
1345 * infcmd.c (do_registers_info): Print floating point registers
1346 in raw hex as well as float format, regardless of whether it is
1347 a "virtual" convertible register.
1348 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1349 regs as a double, just in case it's being used that way.
1350 * values.c (unpack_long): Comment on array/function coercion.
1351 (unpack_double): Argument is in target byte order now. For
1352 integer arguments, just call unpack_long and float the result.
1353 * m68k-tdep.c: include defs.h for "const" handling.
1354 * remote-nindy.c: Use ieee-float stuff.
1355 (nindy_fetch_registers): Unpack double regs to host double, then
1357 (nindy_store_registers): Pack extendeds to host double, flip
1358 around by misusing unpack_double, send as target double.
1360 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1361 zero, as when stopped at the first instruction of a process.
1363 * blockframe.c: Fix filename in comment (param.h => tm.h).
1364 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1365 * tm-68k.h: Fix typos.
1367 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1369 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1371 * coredep.c (fetch_core_registers): Pass end-address of register
1372 section to register_addr as expected. Don't call supply_register
1373 if we'd just pass it garbage.
1375 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1377 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1379 * target.c (push_target, target_info): Cast enums to int for < or
1382 * stack.c (print_frame_info): Identify source file & line
1383 even if we can't print it.
1385 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1387 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1389 Clean up IEEE floating point support.
1391 * ieee-float.h: New file.
1392 * ieee-float.c: Write real routines to convert between host
1393 doubles and various target IEEE extendeds.
1394 * m68k-xdep.c: Eliminate assembler code for extended floats.
1395 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1396 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1397 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1398 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1399 double_to_ieee_extended.
1400 * i960-tdep.c: Define ext_format_i960.
1401 * m68k-tdep.c: Define ext_format_68881.
1402 * sparc-tdep.c: Define ext_format_sparc, though unused.
1403 * Makefile.dist (HFILES): Add ieee-float.h.
1404 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1407 Obsolete the "coffstrip" program in favor of using BFD's strip.
1409 * nindy-share/coffstrip.c: Remove file.
1410 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1411 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1412 * tconfig/nindy960: Remove reference to coffstrip.o.
1414 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1416 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1418 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1419 * dbxread.c: Remove static symfile_bfd.
1420 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1422 * inftarg.c (child_detach): Pop the child_ops vector if the
1423 detach is successful.
1424 * remote-nindy.c (nindy_create_inferior): Don't push a new
1425 nindy_ops since nindy uses the same one for execution and memory
1427 * core.c (core_ops): Use child_attach and child_create_inferior
1428 rather than default attach and create_inferior functions.
1430 Handle floating point registers in core files.
1432 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1433 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1434 This version untested since BFD doesn't yet support sun3 core
1436 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1437 conventions. Fix comments and style. This version has not
1438 been compiled yet, since we have no HP inhouse.
1439 * core.c (get_core_registers): Look for two sections, ".reg"
1440 and ".reg2", and pass both to fetch_core_registers sequentially.
1442 Revise directory path yet again.
1444 * source.c (forget_cached_source_info): Not static any more.
1445 (init_source_path): New default source path is "$cdir:$cwd".
1446 (dir_command): Handle variable arguments ($cdir, $cwd).
1447 (source_info): Print "Compilation directory" rather than
1448 "Originally compiled in" to remind people of $cdir.
1449 (openp): If the path contains $cwd, use current directory.
1450 (open_source_file): If compilation directory is known, replace
1451 first $cdir in path with the compilation directory.
1452 (print_source_lines): Even if we can't print the lines, set the
1453 current symtab and line for future commands like "info source" or
1454 "breakpoint". Also, error message now contains the file name,
1455 line number, and file access error message.
1456 (_initialize_source): Fix help text to describe changes.
1457 * main.c (cd_command): Forget cached source info when we chdir.
1458 * utils.c (strstr): Add simple implementation.
1460 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1462 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1463 Byte-swap COFF symbol tables if necessary when reading them in.
1464 Use complain() to replace error message in one spot. Needs
1465 corresponding change in bfd/coff-code.h to make some symbol
1466 swapping routines non-static.
1468 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1470 Merge changes from Eirik Fuller, for UTek.
1472 * defs.h (errno): Add declaration.
1473 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
1474 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1475 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1476 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
1477 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
1478 declarations of errno.
1480 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1482 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1483 <rpc/rpc.h> and <rpc/types.h>.
1485 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1487 * i960-tdep.c (examine_prologue): Add new argument limit,
1488 which stops the scan at the end of the prologue, or at the PC.
1489 This fixes a problem where it walks down into the code for the
1490 user's statements if that code looks like function prologues.
1491 Mark Fox and I have been bouncing this code back and forth, making
1492 small changes to it. Callers changed to match.
1494 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1496 Cleanup for gdb-3.94 release final:
1498 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1499 the .c files from vx-share and nindy-share, from the various
1500 macros, since they are not found via ALLDEPFILES.
1501 (SFILES): Add tm-i960.h.
1502 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1503 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1505 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1506 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
1508 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
1510 * am29k-tdep.c: Add contribution line.
1511 (examine_prologue): Cache information about function prologues in
1512 the misc-function-vector to avoid lots of references over the
1513 serial line while examining instructions.
1515 * core.c (core_close): New function made from cleanup_core.
1517 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1518 remote-vx.c, remote.c, target.c, target.h,
1519 Update target_ops vector to add attach, close, and load entries.
1520 Use add_syms_addr_command, not add_file_addr_command, for
1521 add_file. Break out close routine from existing code.
1523 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1524 they are in an obstack.
1525 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1527 (define_symbol): Add symbol type parameter; change callers;
1528 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1529 it to influence the symbol class on the i960.
1530 (define_symbol): Swap LOC_CONST's into target byte order.
1532 * exec.c (exec_close): New function.
1533 (exec_file_command): Call it.
1535 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1536 Fix byte order of frame pointer.
1537 (read_var_value): Result of 0 if var's value can't be found,
1538 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1539 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1540 (locate_var_value): Use read_var_value and use its lazy address
1541 as the location of the var's value. Lint.
1543 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1546 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1547 obsolete Intel versions in favor of vxgdb versions.
1548 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1549 code dealing with byte order of values, which Intel did in host byte
1550 order rather than gdb-4's target byte order.
1551 (i960_frame_chain_valid): Move to nindy-tdep.c.
1552 (examine_prologue, skip_prologue, frame_find_saved_regs,
1553 frame_args_address, leafproc_return, saved_pc_after_call,
1554 pop_frame): Add vxgdb versions from Mark Fox.
1555 (examine_prologue, frame_struct_result_address): Add code
1556 to deal with the saved value of G13 (struct return address
1558 (frame_args_address): Modify Mark's version to prefer the
1559 saved value over the current value in the topmost frame.
1560 Cache result in the frame info to avoid performance hair in
1562 (print_fault): Add gdb960 code for printing faults.
1563 (_initialize_i960): Actually call check_host.
1565 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1566 add stub routines. FIXME, these currently just return zero!
1568 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1569 (attach_command): Call target_attach, not target_open, now.
1571 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1572 (child_attach): Rename from child_open.
1573 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1574 don't confuse it with a zero step_resume_break_address.
1576 * inftarg.c (child_detach): Eliminate inferior_pid test.
1577 (child_files_info): Clean up message a bit.
1578 (child_ops): Use child_attach, not child_open, to attach.
1580 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1581 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1582 findvar.c to here, since it depends on the contents of the
1583 shadow_contents of breakpoints, but keep if #if 0 since it is
1586 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1589 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1590 (ptype_command, display_command): Eliminate have_inferior_p and
1591 have_core_file_p in favor of target_has_stack or
1592 target_has_execution.
1593 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1594 code for actually finding the values of arguments, though we still
1595 keep track of the maximum stack offset for use in printing unnamed
1596 arguments. Handle missing FRAME_ARGS_ADDRESS.
1598 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1599 (struct nindy_regs): Define registers passed to/from nindy.
1600 (nindy_fetch_registers, nindy_store-registers): Translate between
1601 nindy and GDB formats for the registers.
1602 (dcache_init): Statically allocate the cache, since it was being
1603 allocated by a malloc that was never freed anyway.
1604 (nindy_create_inferior): Error, not core dump, if no exec file.
1605 (nindy_before_main_loop): Use target_load, not target_add_file.
1607 * remote-vx.c (net_load): Specify large timeout for load
1608 requests. Allow user to break out with INTERRUPT.
1609 (net_break): Remove useless code, clean up. Change callers.
1610 (parse-args, skip_white_space, find_white_space): Clean up arg
1611 parsing to cope with quoted strings.
1612 (net_wait, net_quit): Never call error, just return status.
1613 (vx_read_register, vx_write_register): Cleanup status checking.
1614 #ifdef the code based on which CPU we are using (960 or 68k),
1615 FIXME, this should be completely general but it isn't yet.
1616 (vx_xfer_memory, vx_resume): Cleanup status checking.
1617 (vx_run_files_info): Improve message.
1618 (vx_load_command): Renamed from vx_add_file_command. Allow load
1620 (net_ptrace): Remove unused routine.
1621 (vx_wait): Adopt code from vxgdb960 to cope with broken
1622 connections to target machine and prompt to disconnect. Remove
1623 debug printouts. Map some EVENT_'s to SIGnals.
1624 (add_symbol_stub, vx_open): Print names of object files we found,
1625 and "ok" if we read their symbols OK. Clarify output in general.
1626 (vx_attach, vx_detach, vx_kill): Add these commands.
1627 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1628 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1629 "info files" output, and create_inferior, since we already have
1632 * stack.c (frame_info): Replace Frame_unknown with 0.
1633 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1634 (return_command): Pop until the PC matches as well as the FP,
1635 so it works even if the FP is shared with another function,
1636 as in "frameless" or "leaf" procedures.
1638 * symfile.c (load_command): renamed from add_file_target_command.
1639 (add_syms_addr_command): renamed from add_file_addr_command.
1640 (add_syms_command): Stub to call target_add_syms.
1641 (_initialize_symfile): Change command names and descriptions,
1642 add-file => add-syms, and load from alias to its own command.
1644 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1645 maybe_kill_then_create_inferior): Default for attempts to start
1646 a process, if one is already running, is to ask about killing
1647 it and retry if yes.
1648 (upstack_create_inferior): #if-0 it, strata obsolete it.
1649 (push_target, unpush_target, pop_target): to_close() a target
1650 before unstacking it.
1651 (target_info): Renamed from target_files_info.
1652 (_initialize_targets): Rename "i files" as "i target", accessible
1655 * target.h: Improve comments about the target_ vectored routines.
1657 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
1658 Convert commenting style to standard GNU style.
1659 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
1660 (SKIP_PROLOGUE): No longer a no-op.
1661 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1662 (*_REGNUM): Sort register numbers.
1663 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1664 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1665 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1666 are now 10 byte extendeds, not 8 byte doubles.
1667 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1668 for nindy versus vxworks targets. FIXME, this should possibly go
1669 in the target vector.
1670 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1671 frame_saved_regs and arg pointer with each frame.
1672 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1673 (FRAME_ARGS_ADDRESS): Use cached result.
1674 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1675 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1676 (PRINT_RAMDON_SIGNAL): Call print_fault.
1677 (POP_FRAME): Now works.
1679 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1680 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1681 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1682 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1685 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1686 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1688 * valarith.c (value_subscripted_rvalue): Avoid handling
1689 floats and doubles specially; it gave alignment errors. Lint.
1691 * valops.c (value_of_variable, value_of_this): Error if unknown
1694 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1695 to avoid alignment problems.
1696 (value_print): Handle unknown value address.
1697 (cplus_val_print): Two args are ignored; remove them. Change caller.
1698 (val_print): Use unpack_long rather than pointer-deref.
1701 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1702 to avoid alignment problems.
1703 (value_being_returned): Error if return value unknown.
1704 (set_return_value): Add bogosity warning, FIXME. *
1706 * TODO: A woman's work is never done.
1708 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1709 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1710 Add ieee-float.o to OBS.
1711 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1712 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1713 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1715 Changes to generalize the VxWorks RPC protocol slightly, to handle
1716 i960 as well as 68000.
1718 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1719 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1720 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1721 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1722 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1723 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1724 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1725 so they will move in target byte order rather than network
1726 byte order (happens to be the same).
1728 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1730 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1732 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1735 Add contribution lines to various files, showing where they
1738 * breakpoint.c (break_insn, check_break_insn_size,
1739 read_memory_nobpt): Remove to mem-break.c.
1741 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1744 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1745 entry has bad register number. This change is not
1746 tested in this release, FIXME.
1748 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1751 * value.h: Force value's contents field to be aligned to hold
1752 at least a double or a long long (if supported). This avoids
1753 doing bcopy's in and out of the contents field.
1755 (step_1): Avoid coredump under obscure circumstances when we
1758 * symtab.h (misc_info): Add field to misc function vector for
1759 any kind of cached information the target code desires. AMD
1760 29000 uses this to avoid repeating examine_function_prologue's.
1762 * coffread.c: Lint. Remove static symfile, read_section_header.
1763 core.c (have_core_file_p): Lint: remove.
1764 expprint.c (print_subexp): Lint.
1765 infptrace.c, valops.c, valprint.c: lint.
1767 Roll in changes from vxgdb-5.0.1:
1769 * symtab.h: Comment byte order of each address class. Add
1770 LOC_LOCAL_ARG for frame-relative args (960).
1771 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1772 symtab.c, symmisc.c: ditto.
1774 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1776 * remote.c (remote_resume): Error if resume with a signal.
1778 * symfile.c (prim_record_misc_function): Clear misc_info.
1779 (fill_in_vptr_fieldno): Check stub type of arg.
1781 * valops.c (value_cast): Avoid looking up names of types whose
1782 name we don't know, to prevent coredump. Sun CC produces typedef
1783 rtx and the name of *rtx is zero...
1785 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1787 Roll in changes from final AMD 29000 port (Tiemann).
1789 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
1790 for ../include/a.out.encap.h. This might not work now that BFD
1791 is separately compiled. Instead, BFD support for encap will have
1792 to translate machine type 29k into the right COFF_MAGIC.
1794 * infcmd.c: Remove references to inferior_pid that aren't used
1795 in actual ptrace calls; use target_has_execution, etc.
1796 (have_inferior_p): Remove function.
1797 (program_info): Print target info rather than "process number";
1798 avoid gratuitous messages unless from_tty.
1799 (run_stack_dummy, finish_command): Set proceed_to_finish.
1800 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
1801 main.c: Lint. Lose have_inferior_p().
1802 inferior.h (have_inferior_p): Remove, lint.
1803 (proceed_to_finish): Add flag to ask that all regs be saved
1804 by normal_stop, for the few commands that need it, speeding up
1805 serial I/O. Add comments to stop_registers.
1807 * remote-eb.c: Remove newline from breakpoint message we grep
1808 for. Never time out when running the user program.
1812 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1814 Roll in changes from vxgdb-5.0.1:
1816 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
1817 symbol in its raw form, we are processing an unlinked ".o" file.
1818 See if the target environment has assigned it an address, using
1819 target_lookup_symbol (VxWorks does), and enter it into the symtab
1822 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
1823 68k versions for a simpler version that assumes zero FP at bottom.
1824 Fixes bug of truncated stack reports.
1826 * target.h (target_lookup_symbol): Define this routine's args
1827 and result, finally.
1829 * target.c (nosymbol): Default routine for target_lookup_symbol.
1830 (target_default): Default lookup_symbol and call_function too.
1831 (files_info): Only print has_all_memory warning if a non-dummy
1834 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
1835 vx_convert_from_virtual): If target does not have floating point,
1836 zero register "values", and avoid doing cross-net conversions.
1837 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
1838 (vx_open): Rearrange code that attaches to target and reads
1839 symbols for all loaded modules, to work if some of the modules
1840 are not accessible. Add symbol_stub() and add_symbol_stub()
1841 as callbacks from catch_errors(). Allow connect attempt to be
1842 interrupted painlessly with ^C (FIXME, there are still some bugs
1843 if the interrupt happens during symbol reading.). Print
1844 final message with puts_filtered, since symbol messages are
1849 * main.c (catch_errors): Only print errstring if non-null.
1850 (command_loop): Avoid an ioctl per command to test ISATTY.
1852 * remote-vx.c (net_load): make static; avoid sophomoric msg.
1853 (vx_xfer_memory): Return correct result!
1854 (vx_files_info): Indicate whether target has float or not.
1855 (vx_lookup_symbol): Complain, not error, if target gone.
1856 (vx_open): Print "Connected" msg before disabling immediate-quit.
1857 [FIXME: lookup_symbol and vx_open changes need testing.]
1859 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
1860 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
1861 contributor lines and update copyrights to 1991.
1863 Changes from an attempted H-PUX host port:
1865 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
1866 defines PT_ATTACH and PT_DETACH but not PT_KILL.
1867 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
1868 * remote-vx.c: include <sys/time.h> for HPUX.
1869 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
1870 "core_file_command" routine to BFD regime. May not work yet.
1872 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
1874 * xgdb.c: Replace X10 version with some VJ version.
1875 (FIXME: Its copyright assignment is not on record.)
1876 * xgdb.c: Update include files to X11R4 (Xaw crud).
1877 (xgdb_display_source, create_text_widget): fix call to
1878 get_filename_and_charpos. Rewack source window stuff for X11R4
1879 (gleaned from include files, and "nm's" of binary libraries, since
1880 I had no doc available).
1881 (append_selection, append_selection_word): Disable with FIXME
1882 since R4 changed interface here.
1883 (create_buttons): Add back the old set of buttons.
1884 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
1886 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
1887 Roll VERSION to 3.94 (not yet final though).
1889 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1891 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
1892 obstack_int_grow, obstack_int_grow_fast): Eliminate
1893 cast on left of assignment, which gives MIPS cc fits and is
1896 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
1897 F_ALIAS. Use printf, not fprintf, when not passing a file
1899 (compare_opcodes): Check that identical instructions have
1900 identical opcodes, complain otherwise.
1902 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
1903 was reported by Roland McGrath.
1904 (unimp): Only match if exactly zero instruction. (Roland)
1905 (branches and traps): Generate all variations of these
1906 instructions with macros, based on a single call that defines
1907 each condition name and its binary representation.
1908 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
1910 * valprint.c (val_print_fields): Take, and use, format parameter.
1911 This means that "p/x struct" again prints the elements in the
1912 desired format. Changed callers.
1914 * stack.c (frame_info): Use filtered output, and indicate wrap
1915 points. Remove kludgy formatting designed to avoid line wrap.
1917 * utils.c (wrap_here): If the line is already full (because
1918 we had printed a long indent or long wrapped string), do an
1919 immediate newline-and-indent.
1921 * m68k-pinsn.c (print_insn_arg): Bugfix from
1922 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
1923 instruction is incorrectly disassembled as bkpt #8.
1925 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
1926 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
1927 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
1928 and then will dump core (sometimes). I traced it back to an
1929 uninitialized symfile_name in psymtab_to_symtab.
1930 (const_vol_complaint): Add quotes to message.
1931 (define_symbol): Only believe line number if gcc_compiled.
1932 Avoid allocating symbol if we will not return it.
1934 Add target strata support so that newly established targets go
1935 into their right place in the target stack (e.g. a new exec file
1936 doesn't wipe out the ability to access the running process).
1938 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
1939 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
1940 and initialize it properly in all the targets.
1942 * target.h: Document strata. Change return type of push_target.
1944 * target.c (nomemory): new function for dummy memory access.
1945 (tcomplain): Rename complain, now also used in symfile.c.
1946 (push_target): Push targets within strata. New return value shows
1947 whether new target is on top of stack or not. Always keep dummy
1949 (target_files_info): Ignore dummy target.
1951 * core.c (core_open): Warn user, and skip accessing file, if the
1952 core target is not the topmost target in the stack.
1953 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
1956 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
1957 target_ops, it doesn't belong there since we have no regs there.
1958 Change name of target from machine => memory to clarify.
1960 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
1962 * Freeze version 3.93 for release.
1964 * Makefile.dist: Handle vx-share and nindy-share subdirs
1965 properly when building gdb.tar.Z.
1967 * symtab.c: lint; add no_symtab_msg to consolidate the messages
1968 printed in various places, so I could change just one copy.
1970 * dbxread.c, coffread.c: Change references to bfd->iostream
1971 to cast to FILE *, now that BFD avoids needing types defined
1972 in other header files.
1974 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1976 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
1977 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
1978 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
1979 (actually gcc -Wall).
1981 * dbxread.c: Remove first_global_sym, last_global_sym, since
1982 they are never referenced.
1984 * defs.h (baud_rate): Declare.
1985 main.c: Define it, and add the -b option to set it.
1987 * gdb-int.texinfo: Add text on how to define a new host or target
1988 architecture, prompted by Per Bothner's questions about MIPS
1991 * gdb.texinfo: Document "complaints". Change doc of -q since
1992 gdb no longer prints the copyright and blurb if you specify a file
1993 name to be debugged (just like Emacs). Add doc for Nindy-specific
1994 command line flags for specifying target serial port and such.
1995 Update copyright to 1991.
1997 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
1998 has taken over for us the job of ripping up executable files. The
1999 crud caused Per Bothner's port to not compile.
2001 * infrun.c (normal_stop): Avoid printing "Program exited
2002 normally" if we are in batch mode. This allows a GDB which
2003 executes a program on a target system, to behave like a Unix
2004 command (input from stdin, output to stdout, no extraneous
2007 * main.c (main): Allow additional machine-dependent command line
2008 options to be specified with the ADDITIONAL_OPTIONS,
2009 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2010 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2011 processing to occur just before the main loop with
2012 BEFORE_MAIN_LOOP_HOOK.
2013 (main): If a "core file" argument is specified, and it is not a
2014 core file, try it as a process ID to attach.
2015 (symbol_completion_function): Attempt to cope with
2016 "show screen-" TAB, not very successfully. This needs more work,
2018 (batch_file): New function, returns whether we are reading
2019 commands from an interactive tty on stdin, or from somewhere else.
2020 Called by normal_stop since it doesn't get from_tty passed down
2021 to it like many commands do.
2023 * remote-nindy.c: Handle command line options for nindy
2025 (nindy_before_main_loop): Prompt user for tty name if they
2026 don't specify it before getting to the interactive command loop.
2028 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2029 and -r command line options. Also add hook before main loop
2030 to make it easy to specify a tty.
2032 * TODO: More things to do, one done.
2034 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2036 * dbxread.c: Make complaint() calls pass pointer, not struct.
2037 Add complaints about badly formatted C++ type information
2038 (const/volatile indicator, and parse errors resulting in
2039 error_type). Fix C++ virtual member fn comment.
2040 (read_struct_type): Avoid bumping pointer if we got a parse
2041 error; this prevents our walking beyond the end of a string.
2042 Terminate loop on null char as well as semicolon.
2043 (process_one_symbol): Fix the LBRAC fix so that it uses the
2044 last previous SLINE, FUN, or SO record's PC address. C++ debug
2045 symbols did not have SLINE records in a useful order compared
2046 to the LBRAC records.
2047 (define_symbol): Handle "catch" records.
2049 * symtab.c (check_stub_type): Added new complain
2050 `stub_noname_complain' and added a consistency check to
2051 keep the debugger from crashing when finishing from an
2052 exception frame. A real fix will be needed later.
2054 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2056 * infcmd.c (attach_command): Make global.
2058 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2059 but make them easy to comment out. Perhaps later they should
2060 be enabled by what CPU you configure for? FIXME.
2061 (VERSION): Roll to 3.93.
2062 (pinsn.o): Remove rule for obsolete file.
2063 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2065 Run down a problem that manifested by printing the wrong function
2066 name in stack traces of read_ofile_symtab. Turned out that the
2067 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2068 the LBRAC symbol with an address in the *data* segment, which
2069 blew our binary search through the blocks.
2071 * dbxread.c: Use the complain() facility consistently to bitch
2072 about problems in the symbol file we are reading.
2073 (finish_block): Add code to check the nesting of the blocks;
2074 complain and Procrust them to fit if wrong.
2075 (make_blockvector): Check the order of the blocks, complain
2076 [but don't cope] if wrong.
2077 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2078 symbols to be sure their PC value is greater than the last SLINE
2079 (line number) symbol we've seen, complaining and adopting the
2080 SLINE PC value if wrong.
2082 * symfile.h (struct complaint, complaint_root, complain,
2083 clear_complaints): Add.
2084 * symfile.c (complain, complaint_root, clear_complaints): Add
2085 facility to deal with non-fatal complaints and to regularize their
2087 (symbol_file_add): Clear complaint counters to allow new complaints.
2088 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2090 * dbxread.c (dbx_symfile_read): Remember the address and size
2091 of the string table for the main symbol file, so we won't read it
2093 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2094 to avoid reading the string table yet again. Lint.
2095 (throughout): Improve filtered output, including word wrap.
2096 (read_range_type): Improve Bothner's fix to handle other types too.
2098 * utils.c: Improve line wrap implementation. Handle unlimited
2099 width by making chars_per_line unsigned.
2100 (puts_filtered): New, easy, function.
2102 * defs.h (puts_filtered): add.
2104 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2105 call the identical sort_symtab_syms() in symfile.c instead.
2107 * expread.y: Suggest the `file' command rather than `symbol-file'.
2109 * command.h (enum var_types): Add zinteger for seroable
2111 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2112 nested if's into a switch.
2114 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2115 we did not stop because of a breakpoint (it must have been for
2116 some other reason, like a "stepi"), so don't print anything.
2118 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2119 doesn't include <sys/types.h>, old SunOS's require it for
2122 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2124 A test port of gdb-3.92.6 to the Sony NEWS.
2127 Don't normally link in remote- or vx stuff.
2128 Some of it doesn't compile, and it wastes space for 99% of the users.
2129 Remove reference to no-longer-used HAVE_VPRINTF.
2130 Fixed BFD_DEP typo to BFD_DIR.
2132 Fix cast in arg to bfd_h_getlong.
2133 Make char *prefix be const.
2134 Fix how certain range types are mapped into builtin unsigned int types.
2136 Remove 2 #includes. They cause errors (on Sony, at least),
2137 and aren't needed (they wern't in earlier versions).
2139 print_address_symbolic should never demangle labels
2140 (since it prints *assembler-level* labels).
2142 [This was superseded by the change to printcmd below.]
2145 Add some "volatile" return types to avoid warnings.
2146 If MISSING_VPRINTF add vprintf function and not just macro
2147 (since vprintf is used in printcmd.c).
2149 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2150 (The latter isn't grokked by some PCC-based compilers.)
2152 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2154 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2155 * nindy-share/coffstrip.c
2156 Added some forward declarations (otherwise, gcc complains
2157 about implicit extern redefined as static).
2159 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2161 Changes inspired by Per Bothner:
2162 * printcmd.c (print_address_symbolic): Take additional parameter
2163 specifying whether to demangle.
2164 (print_address): Pass in asm_demangle to control demangling.
2165 (print_address_demangle): New fn, takes explicit arg to control
2167 * utils.c: Add new vars demangle and asm_demangle, and let them
2169 (fputs_demangled): If !demangle, just print the argument.
2170 (fprint_symbol): If !demangle, just print raw symbol.
2171 * valprint.c (val_print): Call print_address_demangle rather than
2172 print_address, to cause demangling to depend on the global
2173 rather than assembler-level demangling setting.
2174 * WHATS.NEW, gdb.texinfo: Document.
2176 * main.c (show_command): Show all settings if no arg.
2177 (initialize_main): Make "info set" the same as naked "show".
2178 * command.c (cmd_show_list): Handle prefix commands in the
2179 list, and print the name of the setting as well as its English
2180 description and value.
2182 Allow gdb functions to specify where a line should wrap if it
2183 exceeds the size of a terminal line. Use it to make the output
2185 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2186 of the right size when screen width changes.
2187 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2188 (wrap_here): New fn, indicates a point in the output where we
2189 should wrap the line rather than just letting it overflow at a
2191 (fputs_filtered): Implement wrapping.
2192 (n_spaces): New fn, returns a pointer to N spaces.
2193 (print_spaces_filtered): Use n_spaces.
2194 * defs.h (n_spaces): Declare.
2195 * stack.c (print_frame_info): Wrap with 4-space indent after
2196 fn name and before filename and line number.
2197 * printcmd.c (print_frame_args): Wrap with 4-space indent
2198 before each argument name is printed.
2199 * valprint.c (value_print): Wrap with no indentation before
2201 (val_print_fields): Wrap with indentation relative to nesting
2202 level before each field name.
2203 (val_print): Wrap with nesting indentation before array elements.
2204 * command.c (do_setshow_command): Avoid extra newlines,
2205 wrap with 4-space indent around values printed, end with period.
2206 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2208 * breakpoint.c (breakpoint_1): Implement addressprint for
2209 "info breakpoints" display. Change file name and line number
2210 format to " at file:nnn" rather than " (file line nnn)".
2211 * gdb.texinfo: Document.
2214 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2216 Frozen for gdb-3.92.6 release.
2218 README, WHATS.NEW: Update for 3.92.6 release.
2220 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2221 coffread.o from configs since it is now built by default.
2222 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2223 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2224 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2225 from configs since it is now built by default.
2227 Makefile.dist: Update for release 3.92.6. Handle files that
2228 have been moved to ../include, ../getopt, or ../bfd. Add
2229 saber.suppress and tests directory. Add config.status to
2230 the release (it will say "none").
2232 coredep.c: Minor formatting fixes.
2234 These changes were made in early December but only checked in now:
2235 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2236 nindy-share/nindy.c: lint
2237 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2238 register values coming back from the target; we store values
2239 in target byte order everywhere.
2241 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2243 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2245 * valprint.c (cplus_val_print, val_print_fields): New functions,
2246 which print C++ objects. They conspire to avoid printing a
2247 virtual base class more than once, following all the twists and
2248 turns of C++ virtual base rules.
2249 (val_print): Call the above rather than do it by hand.
2251 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2252 symbol file, not for added files like shared libs. This really
2253 needs to be generalized to a timestamp per file.
2255 * core.c (cleanup_core): Avoid coredump if no core file.
2257 * config.gdb: Accept -host or -target in place of +host or
2260 * coffread.c (find_linenos): Avoid desupported BFD interface
2261 to line numbers. We still read them manually rather than using
2262 BFD's "generic" features.
2264 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2266 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2268 * Makefile.dist: Eliminate use of $< in explicit targets.
2270 * readline/Makefile: Use $< rather than $*.c, which does not
2271 include the VPATH in GNU Make.
2273 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2274 copies of tconfig/i960, added for global configuration
2275 compatability. All i960 versions can read both coff and b.out.
2277 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2278 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2281 * TODO: Think of more things to do.
2283 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2285 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2286 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2287 64-bit float conversion.
2289 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2290 equivalent to sun?os4 so global config works.
2292 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2294 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2296 * main.c: Only declare linesize once; declare pagesize not at
2297 all, since it is never used.
2298 (main): Clear newly allocated line before it is used.
2300 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2302 Further stabilization for the Intel 960.
2304 * Makefile.dist: Parameterize the location of the "include"
2305 and "bfd" directories, as well as "getopt". Add symfile.c.
2306 Link in both dbxread and coffread. Fix up "make depend" to
2307 rewack the locations of include, bfd, and getopt in its output.
2309 * README: Document moving include files, improve some of
2312 * coffread.c: Move common code out to symfile.c. Change
2313 symbol_file_command style interface to use new *_symfile_init
2314 and *_symfile_read interface under BFD. Use BFD internal
2315 info to locate line table, symbols, etc.
2317 * core.c (core_fetch_registers): Rename to get_core_registers
2318 to avoid confusion with fetch_core_registers.
2319 (register_addr): Move to coredep.c, which is already machine
2320 dependent. This leaves core.c pretty clean of dependencies.
2322 * coredep.c (register_addr): Accept this routine from core.c.
2324 * dbxread.c: Move common code (with coffread.c, etc) into new
2325 symfile.c. Each psymtab now contains a pointer to the
2326 format-dependent function that knows how to read it in. Make
2328 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2329 (process_one_symbol): Add code to complain about a "compiler bug
2330 we muzzle here", if we actually see it.
2332 * eval.c (evaluate_subexp): Insert missing "break" statements
2333 in code that determines whether a variable is an lvalue in
2334 memory, register, or whatever. I detected this via a compiler
2335 bug in which it *almost* mashed out the whole switch statement.
2337 * gdb-int.texinfo: Add minor sections on configuring gdb for
2338 release, and about the README file.
2340 * infcmd.c (registers_info): Fix formatting somewhat. Still
2341 not as pretty as before, but it handles byte swapping.
2343 * remote-nindy.c: If data cache routines are interrupted while
2344 waiting for the remote end, be sure that any uninitialized cache
2345 blocks are on the free list, not on the valid list!
2347 * symfile.h: Flesh out this header file with all the various
2348 routines and variables that have been merged in from dbxread.c
2349 coffread.c, and symtab.c to symfile.c.
2351 * symfile.c: New file, containing code common to dbxread.c,
2352 coffread.c, and some code from symtab.c. All generic code for
2353 reading symbol files should be in here now.
2354 (unrecord_misc_function): Remove unused function.
2356 * symtab.h: Remove file-reading things to symfile.h.
2358 * symtab.c: Remove file-reading things to symfile.c.
2360 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2361 to decode i960 fault types.
2363 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2364 target.c: Change type of the "resume" function from int to void,
2365 since its result was never used.
2367 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2369 * main.c: Replace "stupid" with "caution"; you now "set caution
2372 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2374 * infcmd.c (do_registers_info): Call val_print to deal with the
2375 byte order of the registers being printed. FIXME, this makes
2376 the formatting of the output uglier.
2378 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2379 defined, call it for signals the debugger doesn't itself use.
2380 The i960 uses this for more detailed fault information.
2382 * remote.c (remote_open): If arg is null, print help rather than
2385 * sparc-xdep.c (register_valid): Avoid declaring size, since
2386 various modules will think of various sizes depending on the
2387 architecture of their tm-file. FIXME, we need protection against
2388 actually entering one of those modules, which would clobber
2389 storage if not for the target architecture compiled into gdb.
2391 * stack.c (up_command, down_command): Always print the frame
2393 (up_silently_command, down_silently_command): New commands
2396 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2398 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2399 more parameters than it used to.
2401 * findvar.c (registers): Increase slop to 256 bytes, which should
2402 protect us against even most RISC machines with large register
2404 (locate_var_value): Move declaration inside related ifdef.
2406 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2407 throughout, to avoid throwing away buffered input from the board.
2408 (nindy_wait): Supply_register takes addr_of_value, not value.
2409 (i960_print_fault): Renamed from i80960_fault.
2410 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2411 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2413 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2414 we can set the PC in the call to proceed(). Unpush nindy_ops
2415 before pushing it on top, to avoid message to user. Eliminate
2416 commentary from Unix machines that just misleads here.
2417 (reset_command): Fix error message to suggest target command.
2419 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2421 Release 3.92.5 as frozen.
2423 Stabilize the merged release...with help from lint, Saber C,
2426 Everywhere: Add include files needed to declare return types
2427 of functions called.
2429 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2431 * breakpoint.h: Add undeclared breakpoint functions, and some
2432 functions for display handling since I couldn't think of a better
2435 * breakpoint.c (insert_breakpoints): Make code for disabling
2436 shared library bkpts more likely to work. It's used when we
2437 rerun a program and stop before the shared library has been
2439 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2440 cast from pointer, so it squeezes through catch_errors.
2441 (bpstat_stop_status): Fix logic broken some time ago. We now
2442 always create a bpstat if the stop address matches a breakpoint,
2443 even if we don't stop there -- just like the old code used to do
2444 before I got my fingers into it (sigh).
2445 (breakpoint_1): Print "ignore count" after "stop only if"
2446 condition, since that's how it actually works.
2447 (mention): Handle watchpoints as well as breakpoints.
2448 (watch_command): use set_raw_breakpoint and mention to do most
2449 of the work (and initialize all the fields!). Only pass one
2450 arg to parse_c_expression, since that's all it takes.
2452 * command.c (not_just_help_class_command): Rename arg to args
2453 since we ignore "unused argument" warnings on vars named "args".
2454 inflow.c (child_terminal_info): ditto.
2455 infptrace.c (kill_inferior): ditto
2456 main.c (catch_errors, version_info, quit_command, pwd_command,
2457 source_command, dump_me_command, editing_info,
2458 set_history_size_command, set_history, show_history,
2460 stack.c (locals_info): ditto
2461 target.c (target_files_info): ditto
2462 valprint.c (set_input_radix, set_output_radix): ditto
2464 * core.c: Remove old variables for handling core and exec file
2465 sections (data_start, data_end, stack_start, stack_end,
2466 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2467 text_end, exec_data_start, exec_data_end, text_offset,
2468 exec_data_offset, data_offset, stack_offset). They're
2469 superseded the more general build_section_table and
2471 (get_exec_file): Mention the `file' command.
2472 (read_memory_check): Rename to memory_error, and only call it
2473 in the case of an actual error.
2474 (read_memory, write_memory): call memory_error.
2475 (core_fetch_registers): Register section name is ".reg".
2477 coredep.c: Remove a bunch of crud now that all this file does
2478 is pull the registers out of a core file.
2479 (fetch_core_registers): Rewrite to actually work, I hope.
2481 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2482 Replace index() with strchr(). Remove all the pre-BFD macro
2483 definitions for accessing the symbol file.
2484 (struct dbx_symfile_info): Encapsulate the information that
2485 dbx_symfile_init needs to pass to dbx_symfile_read in this
2488 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2489 dbx_symfile_discard): Rearrange symbol file reading to divide
2490 the format-specific part from the format-independent part,
2491 leaving the format-independent part such as file name expansion
2492 and opening in symtab.c. This replaces
2493 partial_symbol_file_open and partial_symbol_file_read.
2494 Symbol_file_read, add_file, add_file_target_command,
2495 add_file_addr_command move to symtab.c. Pass an explicit
2496 "mainline" flag for when reading the main symbol table, rather
2497 than relying on the offset address to be zero or nonzero.
2499 (dbx_symfile_read): Don't allow void *'s to be printed as
2501 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2502 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2503 macro" debug version really work.
2504 (read_dbx_symtab): Remove unref'd parameter inclink.
2505 Avoid swapping N_SLINE symbols, for speed.
2506 Merge N_TEXT!N_EXT case with the other external symbol
2507 definitions' case. Add comments.
2508 (start_psymtab): Allocate the symfile name in the psymtab on
2509 the psymbol_obstack, rather than using the caller's storage.
2510 (end_psymtab): Only allocate a dependencies list if there are
2512 (psymtab_to_symtab_2): Use BFD when reopening file to read
2513 its symbols for real.
2514 (read_struct_type): Add FIXME comments where it needs work
2516 (read_huge_number): Add FIXME about overflows.
2517 (read_range_type): Add FIXME about comparing a long to 1<<32.
2519 * coffread.c: Minor changes to move things closer to the new
2520 regime with symtab.c and dbxread.c Major work is still needed
2523 * exec.c (exec_file_command): Remove old variables (see core.c
2525 (xfer_memory): If memory transfer is right at the end of a
2526 section, don't lose.
2528 * findvar.c (get_saved_register): If value is in a real
2529 register, LVAL is lval_register, not lval_memory.
2531 frame.h: Declare print_sel_frame and record_selected_frame.
2533 gdb-int.texinfo: New file, for GDB internals documentation.
2534 Very simple, unformatted doc of cleanups is there for now.
2536 gdbcore.h: Remove obsolete variables that described a.out
2537 section addresses and offsets. (See core.c above.)
2538 Declare fetch_core_registers and registers_fetched.
2540 getopt.c: Declare char *alloca(); even on SPARC.
2542 infcmd.c (run_command): Call target_kill rather than
2544 (step_command, next_command, stepi_command, nexti_command):
2545 Declare from_tty parameter even though we don't use it.
2546 (run_stack_dummy): argument BUFFER is a char array, not
2547 a pointer to REGISTER_TYPE.
2548 (finish_command): using_struct_return needed a value *,
2549 not a struct symbol *.
2551 * infptrace.c (child_xfer_memory): To avoid dependency on
2552 where sections are in memory, try PT_WRITE_D and if that fails,
2553 try PT_WRITE_I. Most Unixes don't care which you use.
2555 * infrun.c (step_resume_break_shadow): Change to array to
2556 match other breakpoint shadow storage.
2557 (clear_proceed_status): Pass address of bpstat to
2558 bpstat_clear, not the bpstat itself.
2559 (child_create_inferior): FIXME comment about if the child
2561 (start_inferior): Remove old function.
2562 (child_open): Use target_kill rather than kill_inferior.
2563 (wait_for_inferior): Ditto.
2564 (insert_step_breakpoint, remote_step_breakpoint): Use
2565 new step_resume_break_shadow.
2567 * inftarg.c (child_wait): If all child processes die,
2568 pretend that the one being waited for exited with signal 42.
2570 * main.c (command_line_input): When scanning for comments,
2571 don't coredump on unclosed quotes.
2572 (quit_command): Use target_kill rther than kill_inferior.
2573 (_initialize_main): Rename class_user from "user" to
2576 * printcmd.c (print_command_1): Initialize "fmt" if no format
2577 is specified by the user.
2578 (print_frame_args): Only add to args_printed if we are
2579 actually fetching args from the stack (avoiding undefined
2581 (_initialize_printcmd): Remove bogus \{ from string.
2583 * remote-eb.c (eb_open): Avoid coredump on no argument.
2585 * remote-nindy.c: Bring out of Intel environment into new
2586 target environment. Remove all conditional compilation on
2587 I80960. Massive hacking throughout.
2588 (nindy_xfer_inferior_memory): New routine stolen from
2590 (nindy_create_inferior): New routine pieced together, probably
2591 not quite working yet.
2592 (nindy_ops): New target_ops struct for nindy.
2594 * remote-vx.c: Use write_memory rather than target_write_memory
2595 to get error checking.
2596 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2598 (vx_create_inferior): Use target_terminal_ours...
2600 * signame.c (_initialize_signame): Always initialize, since
2601 we need the table for things other than psignal.
2603 * solib.c (solib_add): Use symbol_file_add, not add_file.
2604 (solib_address): Return boolean result rather than struct
2605 pointer which nobody else knows the type of.
2607 * sparc-tdep.c, valops.c: Use write_memory rather than
2608 target_write_memory, to get error checking.
2610 * stack.c (locals_info, catch_info, args_info,
2611 get_selected_block, frame_command, up_command): Use
2612 target_has_stack, rather than have_inferior_p or
2615 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2617 * symfile.h: New file, defining the interface between the
2618 generic and object-file-specific symbol reading code.
2620 * symtab.c: Move generic symbol-reading interface to symtab.c,
2621 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2622 table to map BFD targets to symbol-reading modules in GDB.
2623 Change index to strchr.
2624 (lookup_struct_elt_type): Use error() rather than hand-made
2625 simulations thereof.
2626 (lookup_partial_symbol): Speedup slightly when length == 0.
2627 (symbol_file_add): New function.
2628 (symbol_file_command): Call it.
2629 (symfile_open, symfile_init): New function.
2630 (add_file_target_command, add_file_addr_command): moved from
2633 * target.c (target_command): use target_kill.
2635 * target.h (target_files_info): Don't declare, never called
2638 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2639 files to determine stack end address.
2641 * valarith.c (value_x_binop, value_x_unop): Change error message
2642 to be more useful. Pass proper argument to value_struct_elt.
2644 * valops.c (value_assign): FIXME comment that long long
2645 bitfields will break here.
2647 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2648 Update `make saber_gdb' to work better.
2650 * TODO: A woman's work is never done.
2652 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2653 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2654 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2655 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2656 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2657 valops.c, valprint.c, exec.c: Lint.
2660 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2662 Continuing Intel 960 port merge of GDB.
2664 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2665 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2666 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2667 Wack over "make depend" so it handles files in subdirectories
2668 vx-share, nindy-share, bfd, and in the current directory.
2670 * blockframe.c (get_prev_frame_info): Remove fatal error
2671 if stack not defined.
2673 * core.c (core_open, core_detach): New functions that handle
2674 the old "core-file" command as "target core" and "detach" instead.
2675 (core_file_command): Call them.
2676 (core_xfer_memory): Use common routine xfer_memory.
2678 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2679 dbxread now uses bfd for everything but symbol reading itself.
2680 BFD internals are used to drag out the relevant file offsets.
2681 (partial_symbol_file_open): Change args all around for BFD.
2683 * symtab.c: Rename "value" to "val" everywhere, so we can
2685 (symbol_file_command): New command, moved from dbxread.c
2686 and coffread.c. It uses BFD to read the file, then vectors
2687 based on its type, to dbx or coff symbol readers.
2688 * symtab.h: Extern a few vars for symbol_file_command.
2690 * target.h: Breakpoint takes a char * save area, not a char **.
2692 * valprint.c (val_print): When unpacking bitfields, offset
2693 the address in gdb of the value, if it is declared with a shorter
2694 type. Remove the last "runtime kludge test" of host byte order.
2696 * utils.c: Remove old my_bfd_read routine.
2698 * stack.c (frame_info): Use target_has_stack. Print program counter
2699 register's actual name rather than "pc", since it's called the
2700 "ip" (instruction pointer) on the i960 (sigh).
2702 * target.c (target_command): Add command for selecting a target
2703 type and calling its open routine. This is used for initiating
2704 communication with a particular target, in a generic way.
2706 * tm-i960.h: Update for modern gdb. Remove semicolons from
2707 various macros. Handle reading struct return convention, and
2708 error-out attempts to return structs with the "return" command.
2709 Be sure gdb doesn't think we know how to call functions in the
2712 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2713 to i960_xxx in lower case.
2714 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2715 not being defined yet.
2717 * remote.c (remote_open): Call start_remote to initialize
2718 wait_for_inferior during open.
2719 (remote_xfer_inferior_memory): Return length written rather
2722 * remote-vx.c (target_command -> vx_open): Use new generic
2724 * remote-eb.c, inftarg.c, exec.c: ditto.
2726 * infrun.c: Fix comments.
2727 (attach_program -> child_open): Use new generic target command.
2728 (wait_for_inferior): Clear saved register values before target_wait,
2729 so target_wait can set some of them if convenient.
2731 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2732 Return success indicator, not void.
2733 (child_xfer_memory): Avoid fetching initial word if we'll
2734 overwrite it anyway.
2736 * infcmd.c (attach_command): Use new generic target open routine.
2737 (_initialize_infcmd): Update doc on attach and detach commands.
2738 (do_registers_info): Merge in a byte-order problem as a FIXME
2741 * findvar.c (find_saved_register): Avoid problem in current frame.
2742 (read_relative_register): Ditto.
2743 (write_register): Convert byte order on the way out.
2745 * exec.c (file_command): Add.
2746 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
2747 (xfer_memory): Common function between core_xfer_memory and
2749 (exec_xfer_memory): Use it.
2751 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
2753 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
2754 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
2755 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
2757 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
2759 Merge Intel 960 port of gdb, continuing...
2761 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
2762 symbol_file_command): Pass from_tty arg to hush 'em up.
2764 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
2765 Add magic numbers for 960 COFF format.
2767 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
2769 Merge Intel 960 port of gdb, from Intel "1.2" release.
2771 CHANGE_LOG entries from their port, which was based on
2774 Thu Sep 6 11:02:22 PDT 1990
2775 Remove temp file if download is interrupted.
2777 Wed Aug 1 09:08:33 PDT 1990
2778 Now uses binary protocol to talk to NINDY.
2779 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
2780 Times out after 5 seconds when trying to talk to NINDY.
2782 Tue May 29 12:54:49 PDT 1990
2783 Added variable baud rate (-b switch).
2784 Source code reorganization.
2786 Thu Apr 26 11:09:55 PDT 1990
2787 More cleanup of batch mode; specifically, execute "-s", "-e", and
2788 "-se" switches as soon as they are encountered on the invocation line.
2790 Fri Apr 20 13:47:15 PDT 1990
2793 Thu Apr 19 09:54:28 PDT 1990
2794 Add 'reset' command.
2796 Wed Apr 18 09:48:07 PDT 1990
2797 After opening remote tty, wait for 1 second to go by without input
2798 from it before trying to talk to NINDY (fixes problems with the
2799 Heurikon HK80/V960E).
2801 Mon Apr 4 16:33:05 PDT 1990
2802 Some output was not being suppressed in 'batch' mode.
2804 Thu Mar 22 15:31:11 PST 1990
2805 Ask user if old symbol table should be deleted when new file is
2808 Allow user to run a program downloaded before gdb960 was brought up.
2810 Correct "exec-file" help message for i80960 context.
2812 Correct bug in calculating user space address: could occasionally
2813 corrupt user program.
2815 Make sure to zero low-order bits in rip's because of bug in 960CA
2816 A-step part: could cause operation faults when "next"ing across
2819 Correct bug that made it impossible to get source line numbers for
2820 code loaded at addresses higher than 0x7fffffff.
2822 Wed Jan 10 12:43:22 PST 1990
2823 Open remote tty for exclusive use.
2825 Fri Jan 5 12:14:42 PST 1990
2826 Correct disassembly (CA manual was right after all):
2827 opcode for sysctl is 0x659
2829 Mon Oct 23 12:03:04 PDT 1989
2830 Use G960BASE and G960BIN environment variables to find 'sx' utility.
2832 Mon Oct 16 14:15:09 PDT 1989
2833 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
2835 Mon Oct 2 15:56:31 PDT 1989
2837 Added 960CA disassembly support.
2839 To simplify maintenance:
2840 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
2842 - eliminated opcode.h: incorporates tables into i960-pinsn.c
2843 - moved 960-specific routines from i960-pinsn.c to i960-md.c
2844 - made disassembly interface identical to that in gdmp960.
2848 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
2850 * target.h: Allow targets to stack. Add target_has_memory,
2851 _registers, etc. Restructure memory access and "info files"
2852 to walk the target stack.
2853 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
2854 target.c: Change tables to match target.h.

2859 * remote-eb.c: New memory regime, new info files.
2860 * remote-vx.c: New memory regime, new info files. Now use
2861 separate targets for VxWorks attachment to machine, and
2862 actually running a process under VxWorks, since one has
2863 stack & execution & regs and the other doesn't.
2864 * remote.c: New memory regime, new info files.
2865 * sparc-xdep.c (fetch_core-registers): New memory regime.
2866 * target.c: New routines and support for stacked targets,
2867 new memory regime, new info files regime.

2873 * exec.c (build_section_table): Iterate all sections and
2874 record what gdb needs to know about them.

2881 * dbxread.c: Quick changes to make it compile with new BFD.
2882 * utils.c (error): Avoid using bfd_error in generic routines.
2884 * core.c (core_fetch_registers): Get from the ".regs" section of
2886 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
2888 * inferior.h (attach_flag): Export.

2896 since been deleted, such as temporary breakpoints.
2897 infcmd.c (program_info): ditto.
2899 * core.c (core_file_command): Display the frame where the core
2904 * remote-vx.c (target_command): Merge in target command from
2905 targ-vx.c. A few other cleanups.
2907 * TODO, Projects: Lots more stuff to do...
2909 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
2911 Massive changes to wall off the remote-debugging interface
2912 behind a function vector. The port to handle VxWorks targets
2913 is also part of this.
2915 All files: Replace references to renamed functions,
2916 remove references to remote_debugging, remove references to
2917 have_include_file, have_core_file in favor of target_has_stack,
2918 target_has_memory, etc.
2920 * Modularize the breakpoint interface.
2921 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
2922 a breakpoint instruction.
2923 breakpoint.c: struct breakpoint's shadow_contents now sized as
2925 (insert_breakpoints): Vector to target to install breakpoints.
2926 (remove_breakpoints): Vector to target here too.
2927 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
2928 sparc-tdep.c (single_step): Use new breakpoint interface for
2929 the single-step breakpoints.
2930 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
2931 New file, contains routines to insert and remove breakpoints by
2932 reading out the old contents and later replacing them. This is
2933 how ptrace breakpoints work, and many remote systems as well.
2935 * tm-vxworks68.h: New config file, overrides a few things for
2936 Wind River's preferences.
2938 * target.h: New file, for transfer vector used to talk to the
2939 inferior (child, attached, core, exec, remote, etc). All accesses
2940 to the thing being debugged should come through these vectors.
2941 target.c: New file, routines to handle transfer vector.
2942 (various files): Add transfer vectors XXX_ops for the various
2943 targets and pseudo-targets (core files, etc) we support.
2945 * breakpoint.c (bpstat_stop_status): Further explorations of
2946 watchpoints and why things don't work all the time.
2947 (bpstat_alloc): New fn to allocate a bpstat and chain it.
2949 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
2950 the local gdbinit if it doesn't already have it.
2952 * core.c (core_ops): add and install.
2953 Allow core debugging without exec file.
2955 * dbxread.c (free_and_init_header_files): Merge two fns.
2956 (end_symtab): Free named symbol table when a new version comes in.
2957 (read_dbx_symtab): Relocate all kinds of symbols with base
2958 address. First step toward handling different text, data, bss
2960 (add_file_addr_command): Renamed add_file_command.
2961 (add_file_command): Vector to remote handler.
2962 Add "load" as an alias for "add-file" command.
2964 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
2965 non-returning functions.
2967 * exec.c: Add exec_ops, and push it as a target when an exec
2970 * infcmd.c (run_command): Pass executable file name and arg list
2971 separately when starting an inferior. Permit "run" when no exec
2972 file is specified, for VxWorks.
2973 (detach_command): Move to child_detach in inftarg.c.
2975 * inftarg.c: New file. Unix-child-specific routines, and the
2976 child_ops structure.
2978 * inferior.h (registers): Export "registers" as the way for
2979 target dependent register handlers to find gdb's local copy of
2980 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
2981 since it is now used by places that want wait_for_inferior to
2982 handle the grunge but want to see every trap from the inferior.
2984 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
2985 Eliminate remote_debugging hooks in terminal handling.
2987 * infrun.c: Replace start_inferior with child_create_inferior.
2988 Move all the hair of Unix shells and ptrace idiosyncracies into
2989 child_create_inferior, so remote handlers don't have to deal.
2990 Remove running_in_shell. Rename stop_after_attach to
2991 stop_soon_quietly, and use it in a few other places where we want
2992 to just call wait_for_inferior and get control back on the first
2993 trap. trap_expected now never takes a value > 1.
2994 (init_wait_for_inferior): Initialize static vars when a new
2997 main.c (gdbinit): Add new hook for .gdbinit file name, let
2998 it be overridden by config files as GDBINIT_FILENAME.
2999 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3000 Both of these are used for VxWorks gdb.
3002 mcheck.c: rename include file "gmalloc.c" to avoid problems
3003 with system include file "malloc.c".
3005 param-no-tm.h: New include file, same as param.h but does not
3006 include the default "tm.h" file. This is used in files where
3007 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3009 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3011 remote-vx.c: New file, VxWorks remote debugging support. Uses
3012 RPC routines that are shared with the target system, in directory
3015 remote.c: Vectorize remote interface.
3017 source.c: Globalize source_path, and make an alias "l" for "list"
3018 since we now have the "load" command.
3020 sparc-xdep.c: Use new param-no-tm.h.
3022 symmisc.c (free_named_symtab): Add new function from Wind River.
3023 However, ifdef it out for now while we think about what it should
3026 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3028 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3029 non-Unix-children handle this with their own code in the target
3032 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3033 source and target lists. Add vx-share to default list of include
3034 directories. Add new files to src and target lists: mem-break,
3035 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3036 ${srcdir} versions of munch and createtags are used.
3038 * valops.c (find_function_addr): Split out of call_function.
3039 (call_function_by_hand): Rename call_function; this function
3040 calls functions in the target by laboriously patching the target
3041 word-by-word with the right stack, args, regs, etc.
3044 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3046 Handle AMD 29000 a bit better.
3048 * remote-eb.c (readchar): Mask received char log to make it readable.
3049 (remote_start): Pass arguments down to executing program.
3050 Make startaddr unsigned.
3051 infrun.c (start_inferior): Accept args, pass them to
3053 infcmd.c (run_command): Pass args down to start_inferior.
3055 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3056 the target object file format.
3057 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3059 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3060 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3062 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3064 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3065 * TODO: We did a few things, we have more to do though.
3067 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3068 * inflow.c (inferior_died): Clear deferred stores.
3070 * Debug problems with dummy frames and calls to the inferior.
3071 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
3072 * sparc-tdep.c (do_restore_insn): Simplify.
3073 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3074 (sparc_push_dummy_frame): Simplify and fix what we push.
3075 (sparc_pop_frame): Slightly more hair here, deciding whether
3076 we are restoring a saved PC or returning to a return address in %i7.
3077 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3079 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3080 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3081 * obstack.h (chunkfun): ditto.
3082 * defs.h (xmalloc, xrealloc): ditto
3084 * utils.c (quit): Grab the terminal from the child if necessary.
3086 * inflow.c (term_status_command): Rename to term_info, change
3089 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3090 (is_delayed_branch): Speed up.
3091 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3092 Still missing some float ops, and needs testing.
3094 * Support for input and output radixes other than base 10
3095 * defs.h (input_radix, output_radix): Declare.
3096 * expread.y (yyparse, parse_number): Handle changes of input
3097 radix, and ambiguous names-or-numbers in radixes >10.
3098 * printcmd.c (print_scalar_formatted): Print formatted hex
3099 numbers in varying column widths.
3100 * valprint.c (val_print): Use output_format to print scalar ints.
3101 (set_input_radix, set_output_radix, set_radix): Create.
3102 (set_output_radix): Set output_format from output_radix.
3103 (_initialize_valprint): add `set radix' but leave the others off.
3105 * main.c (execute_command): Let stupid questions be turned off.
3106 (_initialize_main): Handle "set stupidity", etc.
3108 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3109 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3111 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3113 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3114 bfd stuff is still screwed up, but with some manual work, it
3117 * breakpoint.c (bpstat_do_actions): Start over if a command
3118 proceeds the inferior, since the inferior will have stopped and
3119 will need to have its new stop-actions taken care of.
3121 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3122 compiler fits, simplify it.
3124 * gdb.texinfo (directory command): Doc new dir command.
3125 source.c (directory_command): "dir" now puts things on the front
3126 of the path, moves dups up front, and handles multiple names
3127 on the command line, inserting each one in order. It also
3128 blows away cached line and full_filename info.
3130 * stack.c (backtrace_command): Skip "more stack frames follow"
3133 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3134 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3135 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3136 The only odd one was Gould NP1, which had defined vprintf to
3139 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3140 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3141 variable, inspect_it.
3142 valprint.c (print_string, val_print): Use the global inspect_it
3143 to indicate whether to print in Epoch style or normal style.
3145 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3147 * printcmd.c (call_command): add an alias for the "print" command
3148 which runs expressions and doesn't print the result if void.
3149 (print_command_1): implement it.
3151 * command.c: Remove #if 0'd code. Initialize all the fields
3152 in add_cmd (). Rename do_nothing_command to
3153 not_just_help_class_command, and make it externally visible.
3154 command.h: add user_commands to struct.
3155 * main.c (define_command): Don't overload c->function with a char
3156 string as well as a function pointer.
3158 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3159 calling convention of value_struct_elt () that got dropped in
3162 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3163 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3165 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3167 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3168 until a good time (e.g. when we are about to run the child),
3169 saving ptrace calls.
3170 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3171 * tm-sparc.h: define DO_DEFERRED_STORES.
3173 * sparc-xdep.c (store_inferior_registers): when storing float
3174 registers, don't store stack regs too. When storing the SP,
3175 however, DO store the stack regs too. This fixes a bug in which
3176 the dummy frame is not recognized when a call_function finishes,
3177 because its frame pointer (in the stack regs) was never
3179 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3180 even though we don't know how to read them from an inferior.
3181 valops.c (call_function): Comment about storing SP.
3183 * infrun.c (save_inferior_status): Save away the original bpstat
3184 chain so it can be restored later. Install the copied version for
3185 use by whoever saved the status. It will be blow away by
3186 restore_inferior_status, and the original chain restored. This is
3187 important for people who have pointers into the original.
3189 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3190 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3191 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3194 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3196 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3197 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3198 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3200 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3202 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3203 Store the baseclasses in a type struct starting from array element
3204 0 rather than from the unusual array element 1.
3206 dbxread.c: the above.
3207 (virtual_context): Add
3208 Read new debug information about which virtual function table
3209 a virtual function is from, and store it in fn_field.fcontext.
3211 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3212 TYPE_FN_FIELD_STATIC_P.
3214 symtab.c: the above.
3215 valops.c: the above. Handle pointer casts of object *'s.
3216 (search_struct_method): Add.
3217 (value_struct_elt): First arg is now a pointer to a value, and is
3220 valprint.c: the above.
3221 values.c (value_virtual_fn_field): Add type arg. Handle
3222 offsetting to the proper object when calling virtual fns.
3224 (baseclass_addr): Add valuep arg.
3226 * README: Document the current state of BFD config (missing).
3227 * TODO, ChangeLog, Makefile.dist: Roll version.
3228 * WHATS.NEW: Add summary of changes since 3.5.
3230 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3232 * dbxread.c (read_struct_type): Clear bit vectors whenever
3234 symtab.c (B_CLRALL): define.
3236 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3237 using == rather than =. Huh... This fixes the dreaded problem
3238 wherein builtin_type_int becomes TYPE_CODE_FLT.
3240 * core.c (info_files): Show the inferior pid.
3242 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3243 already knows how to look in the source directory.
3245 * Remove psymtab hair from many places. Remove duplicated code
3246 for searching symbol tables. Hide psymtabs from most places.
3247 Make it fast to get from a psymtab to its symtab.
3249 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3250 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3251 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3252 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3253 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3254 new symtab completely. New psymtabs get symtab pointer
3255 initialized to zero. Remove MI warning printf.
3256 symtab.h: Comments. Add psymtab to symtab pointer.
3257 (PSYMTAB_TO_SYMTAB): New macro.
3258 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3259 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3261 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3263 (print_frame_info): Avoid special-casing symbols that have not yet
3266 * source.c (open_source_file): Quick path if we have already
3267 located the source file by its full name.
3269 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3270 find_pc_psymtab. When a name is found in the misc function
3271 vector, search the symbol table for its mangled name, not the
3272 name that the user typed.
3274 * bfd.h: Fix missing comment terminators, make #endifs match.
3276 * valarith.c (value_less): Handle unsigned int comparisons.
3277 Add FIXME about pointer compares, which assume host and target
3278 pointers are the same.
3280 * command.c (do_nothing_command): lint
3281 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3282 fix comments on debug symbol format for visibility. Actually set
3283 visibility of symbols.
3284 main.c (echo_command): lint; use <readline/history.h>.
3285 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3286 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3287 pointing past end of allocated memory; saber complains.
3288 obstack.h: Declare the external functions that we use.
3289 valarith.h: use <string.h>
3290 solib.c (solib_add): lint.
3292 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3294 * main.c (initialize_main): Default info_verbose to off, now that
3295 symbol reading is fast.
3296 (quit_command): Avoid clobbering exec_bfd while quitting.
3298 * Initial BFD (binary file diddling library) merger:
3299 coffread.c: Change AOUTHDR to struct exe_hdr.
3301 core.c: initialize initialized data at compile time.
3302 (core_file_command): Move from coredep.c, convert to bfd.
3303 (xfer_core_file): Convert to bfd.
3304 exec.c (exec_file_command): use bfd routines.
3306 mips-tdep.c: Remove exec_file_command and friends.
3309 * coredep.c: (fetch_core_registers) Convert core_file_command to
3310 fetch_core_registers.
3311 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3313 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3314 (my_bfd_read): More bogosity, which I don't think we call.
3315 (program_name): Remove this atrocity asap!
3317 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3320 values.c: allocate_repeat_value was not clearing the
3321 optimized_out field.
3322 (value_static_field): minor stylistic fix (wrong macro was used).
3323 valops.c (value_struct_elt_for_address): didn't work for C++
3326 * signame.c (_initialize_signame): Initialize signal names once.
3328 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3329 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3330 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3332 * remote-eb.c: Support user-settable baud rates on the serial port.
3334 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3336 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3338 * tconfig/sun3os4: Remove warning about native assembler,
3339 since it also occurs in the xconfig file.
3341 * findvar.c (registers): Allocate some slop after `registers'
3342 to prevent stray accesses from trashing the next variable.
3344 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3345 on the sun-3, by changing the #ifdef from `sun3' (which is not
3346 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3347 vars, which happened to follow `registers' in the executable.
3349 * readline/history.c (history_search): Heed gcc-2's advice
3350 and parenthesize && inside ||).
3352 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3353 tm-29k.c: Insert FSF copyright headers.
3355 * remote-eb.c: Better comments.
3357 * Makefile.dist: Update to 3.91.6.
3358 * TODO: note PREPARE_TO_STORE problem.
3360 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3362 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3364 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3366 * infrun.c (wait_for_inferior, at end): Don't set up
3367 prev_* if the inferior no longer exists.
3369 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3370 CANNOT_EXECUTE_STACK.
3371 valops.c (call_function): Use it.
3373 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3375 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3376 infrun.c (wait_for_inferior, 2 places): Use it.
3378 * values.c (value_being_returned): Only use
3379 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3381 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3382 right thing for remote-eb.c.
3384 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3385 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3387 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3388 (FRAME_FIND_SAVED_REGS).
3390 * findvar.c ({fetch,store}_registers): Check for
3391 REMOTE_{FETCH_STORE}_REGISTER macro.
3393 * findvar.c (get_saved_register): Add argument lval and
3394 change meaning of argument addr.
3395 findvar.c: Change calls to get_saved_register to reflect
3396 new calling convention.
3397 valops.c (value_assign): Use get_saved_register instead of
3398 find_saved_register.
3400 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3402 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3403 an (uninitialized) pointer to one. Use "&" when passing it
3406 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3408 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3411 * coffread.c (symbol_file_command): Put semicolon after
3413 Put safe_to_init_tdesc_context in #if defined (TDESC).
3414 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3415 coffread.c: #include <sys/stat.h>.
3416 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3417 Add missing ')' in check for "lc%" and friends. Remove
3419 Declare read_one_sym() at top of file.
3420 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3421 MC68WRMAGIC can have the same value without causing a duplicate
3424 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3426 * Allow a Makefile to be built without building the
3427 tm and xm file links that screw up builds in subdirectories.
3428 This is done with `config.gdb none', then you can do things
3429 like `make gdb.tar.Z'.
3430 * tconfig/none: Config file for no target system
3431 * xconfig/none: Config file for no host system
3432 * config.gdb: If no TM or XM files are called out by the
3433 host or target file, don't make links for them.
3435 * cplus-dem.c: Add documentation.
3437 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3438 simple error, so the user's gdb doesn't crash due to some object
3439 file problem (e.g. somebody is rebuilding the file out from under
3442 * printcmd.c (print_address_symbolic): demangle the symbol.
3444 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3445 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3446 (alldeps.mak): sort and uniq all results from this; duplicates
3447 hose gdb.tar.Z link building. Remove RCS files from
3448 tconfig and xconfig. Add config files for sun386. Add
3449 a few odd files to OTHERS and HFILES.
3451 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3453 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3454 Roll version number to 3.91.5. Make lint work in bindir.
3456 * README: Document cross-debugging and new file structure.
3458 * blockframe.c: Lint. Include "value.h" to declare read_register.
3459 (find_pc_partial_function): remove duplicate line.
3461 * command.h: Lint. Declare error_no_arg and dont_repeat.
3463 * tm-news.h: Remove inadvertently duplicated stuff.
3465 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3466 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3468 * config.gdb: Allow `config.gdb host target' form. Clean
3469 up previous change that printed bogus messages when you just said
3472 * core.c: #include "command.h" for lint.
3475 * main.c: Remove some casts of enums. Lint.
3482 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3484 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3485 read it from memory. This will allow us to save ptrace calls
3486 eventually. Changed caller single_step too.
3488 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3489 that we aren't going to use, saving many ptrace calls, especially
3490 when watchpointing or single stepping. Use some #define's for
3492 (store_inferior_registers): Ditto.
3493 (core_file_command): Use some #define's for constants.
3495 * tm-sparc.h: Add #define's for some register numbers, so we
3496 can eliminate the use of random constants in sparc-xdep.c.
3498 * stack.c (frame_command, print_frame_info, up_command,
3499 down_command) Remove frame_changed, since it
3500 causes a bug and doesn't seem to do anything useful. In some
3501 places it was used as a flag, in others as a stack level (?).
3503 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3504 default is to use the portable (vprintf) version rather than the
3506 * xm-news.h (MISSING_VPRINTF): Add.
3508 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3510 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3512 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3513 about linking debugged programs -Bstatic in the sun?os4 config
3514 files in tconfig and xconfig subdirectories.
3516 * main.c (main): Remove unreached exit(0) now that we exit
3519 * Create TODO file for online bug list. There are too many
3520 "little" bugs to keep track of on paper.
3522 * Change Projects file to refer to bug-gdb@cygnus.com
3523 rather than kingdon@ai.
3525 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3527 * Makefile.dist (VERSION): 3.91.4 now.
3529 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3530 (condense_misc_bunches): Add sanity check that misc_count is
3531 the same as the number of symbols in the bunch.
3533 * coffread.c: rename init_misc_bunches. Pass an argument
3534 to condense_misc_bunches (a zero).
3536 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3537 every time we are called; don't rely on our caller to do it.
3538 (add_file): Remove call to init_misc_bunches.
3540 * mipsread.c: Only warn, don't error, if unknown symbol types.
3541 This keeps an old gdb from falling on its face if it sees newly
3542 extended symbol info. Rename init_misc_bunches.
3544 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3546 * Merge in changes from Per Bothner for DECstations and other
3547 MIPS stuff. The rest is Bothner speaking:
3549 The next message is a merger of Alessando Forin's mips port with
3550 mine. I've tried to use my good if biased judgment to get
3551 the best of both. It *does* need testing.
3553 Some of the changes are general, *not* mips-specific.
3556 Didn't believe in little-endian bit order.
3557 There are still inconsistencies about whether flags
3558 like BITS_BIG_ENDIAN are integer (#if ...) or
3559 boolean (#ifdef ...). I tried to paper over them.
3561 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3562 Moved some misc_function code that was common to
3563 {dbx,coff,mips}read.c to symtab.c.
3564 In the process, I think I cleaned things up a bit.
3565 At the same time, moved obsavestring and obconcat to symtab.c.
3568 Removed obsolete condense_addl_misc_bunches (use
3569 condense_misc_bunches(1) instead).
3572 Needed to include <sys/dir>, at least on DECstations.
3574 valops.c, mips-tdep.c, tm-mips.h:
3575 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3576 conventions (when STACK_ALIGN is insufficient).
3577 Needed on mips, where doubles need 8-byte alignment,
3578 but ints only need 4.
3581 Removed cruft that was not being used.
3582 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3585 Print $ before register-names (I think that makes things a little
3587 Never print two instructions, even if one delays.
3588 Removed hex-disassemble set_cmd. (This is not mips-specific,
3589 so I think the argument is whether it is generally worthwhile or not.
3590 I'm inclined to think not, given how easy it is to
3591 convert between radixes in gdb.)
3594 This is basically Alessando's code.
3595 It doesn't use obstacks; I changed it to use obstacks
3596 in a few minor places where using malloc causes a
3597 memory leak. (Probably, more places could/should be changed.)
3598 I added record_misc_function where it was missing.
3599 In symbol_file_command and add_file_command, I tried
3600 to make the code consistent with more recent versions.
3601 Minor sylistic changes in parse_procedure.
3602 Make a .gdbinfo. psuedo-symbol point back to the real
3603 procedure symbol (using the isym field).
3606 This is basically from my port, but with a lot of details
3607 and a number of routines merged in from Alessando's version.
3608 I basically used my code "raw" backtrace (use heuristics
3609 from the actual code, rather than symbol table info) - though
3610 the idea is Alessandro's. I feel my code is a little cleaner
3611 here, particularly in being a little more flexible, such as being
3612 able to handle gcc-produced code (which it now can).
3613 It also doesn't do frame caching (which is not useful
3614 more recent gdb versions).
3615 I also used my code for push_/pop_dummy, more or less.
3616 I tried to incorporate AF's code for testing sigtramp
3617 while backtracing; I probably got it wrong.
3618 Added mips_print_register, which tries to scrunch as much
3619 information as possible on a screen...
3620 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3621 under mips-pinsn.c), I don't see anything mips-specific here,
3622 and I don't see it being all that useful anyway.
3625 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3626 Use more register names (rather than hard-cases numbers).
3628 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3630 * Hack up 3.90.11 changes:
3632 * Makefile.dist (depend): parameterize $(GCC).
3633 Add solib.c and solib.o.
3634 (readline): Fix vpath for both absolute or relative SRCDIR.
3636 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3637 Also, let the part I didn't understand at least compile so
3638 I can test the rest. FIXME.
3640 * dbxread.c: Fix thinko using strcmp.
3641 (init_psymbol_list): declare static.
3642 (partial_symbol_file_open): Comment cleanups better, avoid
3643 cleaning up the string table since the caller will do that.
3644 Move the stat for mod time into symbol_file_command, temporarily.
3645 (There should be a mod time for each symbol file, eventually,
3646 to control its rereading. FIXME.)
3648 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3649 SunOS, which gives error for shared libs otherwise. (From
3650 Schaefer, probably FIXME needs work for portability.)
3652 * solib.c: Move #include "param.h" to work.
3653 Lowercase all the Uppercase Letters In the Messages.
3654 (find_solib): Clean up inferior_so_name for debug printouts.
3655 Allow no argument, to mean all shared libraries.
3657 * symmisc.c: include param.h to get CLEAR_SOLIB.
3659 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3661 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
3662 to 3.90.11. ChangeLog entries below are from this.
3664 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3668 * Makefile.dist (HFILES): Add tm-sunos.h.
3670 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3674 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
3676 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
3678 * sparc-opcode.h Added single-operand version of rett.
3680 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3682 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
3683 Put parens around gcc_p in expansion.
3685 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3687 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
3689 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3691 * Changes for Sun shared libraries:
3692 blockframe.c (find_pc_partial_function): If a non-text symbol
3693 is found, set *address = pc - FUNCTION_START_OFFSET.
3694 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
3695 Disable breakpoints instead of giving an error.
3696 source.c (select_source_symtab): Initialize cs_pst.
3697 symmisc.c: Call CLEAR_SOLIB if defined.
3698 symtab.h: Make text{low,high} CORE_ADDR not int.
3699 (psymtab): New field addr.
3701 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
3702 (record_misc_function): Give correct type for N_DATA symbols.
3703 (condense_misc_bunches): do "misc_function_count = j" regardless
3705 Take code which is shared between symbol_file_command and
3706 add_file_command and put it into partial_symbol_file_{open,read}.
3707 Split add_file_command into add_file_command and add_file.
3708 Make psymtab_to_symtab read in the string table if the file
3710 Two new parameters to read_dbx_symtab and start_psymtab.
3711 tm-sunos.h: New file.
3713 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3715 * infcmd.c: Change cont_command to continue_command and "cont"
3718 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3720 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
3722 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
3724 * values.c (USE_STRUCT_CONVENTION): Check for structures of
3725 size 1,2,4,8 rather than size < 8.
3727 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
3728 as necessary, not just once.
3730 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3732 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3734 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3736 * tm-news.h: Add CALL_DUMMY_*.
3738 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
3740 * config.gdb: In list_host, list_target, use ${i}, not $i.
3742 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3744 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
3746 * sparc-opcode.h: Change all store floating-point state register
3747 instructions to have the right match & lose fields.
3749 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3751 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
3753 config.gdb: If srcdir != ., create readline directory and
3754 copy a makefile into it.
3756 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
3757 consistency with POSIX.
3759 * breakpoint.c (bpstat_stop_status): Disable watchpoint
3760 when we exit its exp_valid_block.
3762 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
3764 * Makefile.dist: Bump version to 3.91.3.
3766 * Clean up handling of breakpoint commands (somewhat).
3767 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3769 inferior.h: Add breakpoint_proceeded to inferior status struct
3770 and globals; save it and restore it.
3771 (clear_breakpoint_commands): Cleanup, remove old #define.
3773 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3774 (save_inferior_status, restore_inferior_status): handle it also.
3775 (proceed): Remove earlier code that set breakpoint_proceeded.
3776 It is now set only in clear_proceed_status.
3777 (clear_proceed_status): Cleanup, use bpstat_clear rather
3778 than clear_breakpoint_commands. No callers need the stop_bpstat
3779 between clear_proceed_status and proceed.
3781 infcmd.c: Add breakpoint_proceeded definition and comment.
3782 (cont_command, jump_command, signal_command): Move call to
3783 clear_proceed_status right next to call to proceed.
3785 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3786 caller's argument while running down the chain of breakpoints.
3787 Use new variable "breakpoint_proceeded" to determine when
3788 a command that it executes moves the inferior past the
3790 (bpstat_clear): Handle NULL argument.
3791 (bpstat_clear_actions): Avoid useless call to
3792 breakpoint_auto_delete.
3793 (delete_breakpoint): Clean up bpstat's that are pointing to
3794 the deleted breakpoint from the stop_bpstat chain.
3795 (breakpoint_auto_delete): Simplify.
3797 * Clean up handling of EOF, error on stdin, etc. This was
3798 prompted by a network problem that caused gdb to go into an
3799 infinite loop filling up its malloc'd memory.
3801 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
3802 not clear_breakpoints_commands, which is now gone.
3803 (main): If command_loop returns (e.g. from EOF on stdin), do
3804 a quit_command (looping back to command_loop if quit_command
3805 doesn't really quit).
3806 (command_loop): check result from command_line_input and
3807 exit if it returns NULL, rather than passing the NULL to
3809 (gdb_readline): Free malloc'd result space before returning
3812 * utils.c (query): Handle C-d to mean "yes", just as if the
3813 input was not a terminal. Also avoid infinite loop if EOF
3814 occurs in mid-input-line before newline. This allows
3815 query to be used at EOF on stdin with reasonable results.
3817 * infrun.c (proceed): Set breakpoint_proceeded.
3819 * values.c (value_as_long): Avoid infinite recursion for enums.
3820 (_initialize_values): Fix typo in help msg (kingdon).
3822 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
3823 RL_LIB for linking. This allows -lreadline for linking
3824 and nothing for dependencies, once readline is a real library.
3826 * config.gdb: Jim Kingdon: give useful error message if the
3827 host or target type is not recognized.
3829 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
3830 it just defines it. Dumb, but deal with it.
3832 * Jim Kingdon suggests:
3833 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
3835 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
3837 * Makefile.dist (VERSION): Bump version # to 3.91.2.
3839 * Clean up Bothner's changes.
3841 * blockframe.c (clear_pc_function_cache): New function.
3842 * blockframe.c: remake cache_pc_function_* static.
3843 * dbxread.c (symbol_file_command): remove references to
3844 cache_pc_function_* variables.
3845 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
3846 * printcmd.c: Avoid kludging a global variable (addressprint)
3847 to avoid printing the address of a string twice. Instead,
3848 pass the format letter 's' down low enough that it can be seen
3849 to avoid this problem.
3850 (print_formatted): Pass format arg to value_print.
3851 (restore_addressprint): Remove function.
3852 (do_examine): Avoid hacking addressprint, cleanups and such.
3853 (print_frame_args): Add a comment to a Bothner change.
3854 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
3855 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
3856 to wipe out the values cached in blockframe.c.
3857 * symtab.c (find_method): Add comment saying how big you must
3858 allocate to be "big enough". Per being terse again.
3859 * valprint.c (val_print): Handle format letter "s" to print
3860 strings without addresses. Add comment to vtbl printing code
3861 which casts with wild abandon. Rearrange reference-printing
3863 @0xaddr: value (print w/addressprint)
3864 value (print w/~addressprint)
3865 @0xaddr (parameter lists w/addressprint)
3866 or nothing (parameter lists w/o addressprint)
3868 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
3870 * Merge more changes from Per Bothner:
3872 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
3873 annoying) that I tried to improve it. Here are my suggestions.
3875 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
3878 Do automatic de-reference when taking the address of a reference.
3880 Don't deref_ref when printing parameter lists.
3882 More attempts at treating refernences properly.
3884 In val_print, if deref_ref==0, don't print dangling " = ".
3886 Add COERCE_REF macro, which de-references an REF.
3888 * Merge changes from Per Bothner:
3890 * Fixed (Sony news)-specific configuration problems.
3891 * Fixed other problems with using vanilla pcc and libc (enum problems;
3892 assumption that vsprintf exists).
3893 * Some major speed-ups (finc_pc_partial_function now caches a match;
3894 parsing avoids duplicate symbol_lookup calls).
3895 * Changed handling of baseclasses (no longer use baseclasses field
3896 of struct type, use the first n_baseclasses fields instead).
3897 * Various minor changes/fixes, most C++-related.
3900 Cache the most previous match from find_pc_partial_function.
3901 (Save both low and high ends of matching function's pc range.)
3902 This speeds up the loop of infrun.c:wait_for_inferior quite
3903 a bit, and makes step/next commands much zippier.
3905 Added an enum->int cast (otherwise, some compilers barf).
3907 No longer set baseclass offset to 0, since multiple
3908 inheritance now mostly works.
3909 Added a number of casts, to shut up compiler warnings
3910 (after stabs where made enums, not ints).
3911 When discarding a symbol table (in symbol_file_command),
3912 must clear the cache introduced in blockframe.c.
3913 Don't convert $vtbl_ptr_type to vtbl any more.
3914 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
3915 Mask off sign bit emitted by g++ for virtual table offset.
3916 Set voffset to -1 (not 1) for static member functions.
3918 Changed parsing/lexing of names to avoid doing symbol lookup twice
3919 (once when lexing to determine symbol class, once for real).
3920 Now only call symbol_lookup once. Fields of 'this' win especially big.
3922 Subpress printing addr twice in the case of 'x/s addr'.
3924 lookup_basetype_type is no longer used.
3925 Add find_methods as recursive helper function to decode_line_1.
3926 This allows multiple inheritance to work.
3927 Also, once one or more matches has been found, do not look in
3928 base-classes. (Baseclass methods would be overridden, anyway.)
3930 Removed baseclasses array in struct type.
3931 Instead of using baseclasses[i], use fields[i-1].
3932 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
3933 Changed sign convention of voffset (previous was inconsistent).
3935 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
3937 Used to assume existence of vsprintf. Re-written to not need it
3938 if HAVE_VPRINTF is undefined.
3940 typecmp was too pessimistic. Made it less so.
3942 Don't print space after address.
3943 If vtable points to a misc symbol (with 0 offset), print it,
3944 since that indicates the actual class of the object.
3945 Changed ype_print_derivation_info to use new inheritance
3946 scheme (without baseclasses vector).
3948 In value_primitive_field, fixed some bugs left over from previous set of fixes.
3949 Also, changes needed because TYPE_BASECLASSES were removed.
3951 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
3953 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
3956 If there is no path set, and the symbols don't indicate what directory
3957 a file was compiled in, look in the current directory. But either
3958 a path or a known compilation directory will prevent this.
3961 Three independent bug fixes:
3962 * Remove the #if 0 block that breaks some stuff.
3963 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
3964 adapt gdb to either SunOS 4.0.* or 4.1.
3965 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
3968 Instantiate the class T when looking for methods in it. (Tiemann@sun)
3971 (type_print) Demangle the name being printed.
3972 (type_print_base) Handle botched demangling without coredump (tiemann).
3975 (check_stub_method): Document routine.
3976 (tiemann) fix bug for no-arg functions
3977 Avoid clobbering beyond end of malloc'd storage.
3978 Terminate the argument list properly.
3980 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
3982 * Changes merged by John Gilmore:
3985 In breakpoint_1, use new print_address_symbolic instead
3986 of find_pc_partial_function. (This forces use of assembler-level
3987 addresses, and avoids misleading non-mangled source-level names.)
3989 Generalize ansi argument such that -1 means skip arglist totally.
3990 Removed global variable print_ansi_qualifiers (which made
3991 code non-reentrant), in favor of extra explicit arguments
3992 to internal routines.
3994 Add new helper function print_address_symbolic.
3995 Use find_pc_misc_function instead of find_pc_partial_function
3996 (since we want assembler-level symbols here).
3998 Print unknown function as just "f (...)", not "f (...) (...)".
3999 Use new fputs_demangled explicitly.
4001 Fixed a typing violation (problem: value.h cannot be imported
4002 without renaming many variable in this file).
4003 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4004 decode_line_1: Moved forward some never-reached code.
4005 Made decode_line_2 skip function prologues correctly.
4007 fputs_filtered should not demangle by default.
4008 Add new fputs_demangled to demangle on demand..
4010 Change value_struct_elt to use value_primitive_field (using recursive
4011 utility function search_struct_field). This allows foo.bar to work
4012 for multiple inheritance (so far only for data fields).
4013 Change check_field in the same way (recursive helper function
4014 to support multiple inheritance).
4015 (Note: there are more of these problems that I haven't fixed.
4016 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4017 value_of_this: 'this' symbol name is now just "this", note "$this".
4019 Don't print static members.
4020 Avoid printing "members of <type>" if there are none.
4021 Simplified type_print_derivation_info by merging duplicate code.
4022 Remove useless blank lines in type_print_base (ptype command).
4024 Added declaration of new routine value_primitive_field.
4026 Added value_primitive_field which is generalized version of
4027 value_field that can handle multiple inheritance (non-zero offsets etc).
4028 Re-implemented value_field to call value_primitive_field.

4032 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4033 delete the whole environment. Karl Berry reported the bug.
4034 * source.c - fix openp to avoid //'s in filenames, which
4035 trigger an Emacs bug causing it to not be able to find files
4036 when running gdb in a window.
4037 * dbxread.c - zap the #if 0 that botches the add-file code.
