1 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
4 Minor rearrangement of refcard permits two new make targets--
5 gdbrc.dvi DVI output for refcard, using CM fonts
6 gdbrc.ps PostScript refcard, using PS fonts
8 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
12 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
13 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
15 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
17 * doc/gdb.texinfo: last changes for release.
18 Minor typo and formatting fixes; incorporated most fixes remaining from
19 filed mail commenting on earlier drafts.
21 Added warnings: pipes don't work in run command;
22 conditions are converse of assertions;
23 step over fn without debug info goes to next fn;
24 vars may have "wrong" values near fn entrance, exit
26 Added example from Kingston on printing repeated nonadjacent values
28 Added explicit mention that in Emacs gdb mode C-c and C-z are like
29 shell mode for signals
31 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
32 doesn't sound so much like its parent "Stopping and Continuing"; also
33 moved entries on continue to top of section, so they don't get lost.
35 Improved installation directions in appendix, added manual formatting
38 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
40 * configure.in: Remove xm.h and tm.h even if we aren't linking
41 new ones, so "./configure sun4; ./configure none" does the right
42 thing. Assume that alldeps.mak and depend are already built in
43 srcdir, and avoid running "make" (particularly "make depend",
44 which involves "gcc") from inside configure. Build Makefile
45 directly rather than building Makefile.conf first.
46 * configure: Regenerate with above changes.
47 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
48 to 3.98. Revise gdb.tar.Z procedure to produce a file
49 called gdb-$(VERSION).tar.Z but which unpacks into a
50 directory called "gdb". Move non-source files out of
51 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
52 (depend): Don't try to do "gcc expread.y".
53 (expread.o): Update dependencies by hand.
55 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
58 Fixed a variety of small typos that prevented info from formatting
59 cleanly; altered too-long heading for GPL Appendix, as discussed
60 w/RMS; Changed date on cover to July 91.
62 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
65 (1) Applied some fixes due to comments from Larry Breed (easier ones
67 (2) Eliminated use of @footnote---had my doubts about it anyways, and
68 it's broken in latest texinfo
69 (3) Introduced *some* use of [] for optional arguments, where
70 explanation is not simpler by listing cmd w arg and cmd w/out arg
71 separately. Still not using @deffn.
72 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
73 couple of headings are too long. Need patches to texinfo or revision
76 * Partial update to README (which still needs work for this
77 release!): (1) use of configure corrected for new script,
78 (2) "make gdb.dvi" and "make gdb.info" mentioned.
80 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
82 * symtab.c (lookup_symbol): Don't complain right off about
83 no debug symbols; use the misc function vector first.
84 (list_symbols): Use misc function vector to find symbols
85 that don't have debug info, and print them.
86 (find_pc_symtab): Temporarily avoid fatal() when psymtab
87 PC range doesn't match symtab PC range, as it does on the
88 MIPS because our symtab reading isn't perfect.
90 * dbxread.c (dbx_symfile_read): Make warning about
91 "no debug symbols" slightly nicer.
93 * source.c (select_source_symtab): If "main" symbol exists,
94 but decode_line_spec can't find line info, don't just return
95 a zero; try other source symtabs or give an error.
97 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
98 their low addresses first, then rip through fixing high addrs.
100 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
102 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
104 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
106 * Minor, mostly mechanical, cleanup of doc subdir for clean
107 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
108 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
110 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
112 Mostly MIPS and general symbol-reading fixups.
114 * doc/gdbint.texinfo: Add documentation on symbol-reading
117 * mipsread.c: Remove kludges around #include "ecoff.h".
118 Remove redefinitions of a_magic, etc, no longer used.
119 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
120 Fix global overview comments to match symfile.c protocol.
121 (mipscoff_new_init): Eliminate cur_hdr if we have one.
122 (mipscoff_symfile_read): Eliminate unused code. Avoid
123 sorting all the symtabs, when all we have read here is psymtabs.
124 The symtabs are sorted as they are created anyway. Tell
125 condense_misc_bunches whether we're mainline.
126 (psymtab_to_symtab_1): Pass filename when recursing, to make
127 stack trace more informative.
128 (parse_partial_symbols): Assume cur_hdr as argument.
129 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
130 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
131 the TYPE_NAME of char *, since that's done in symfile.c.
132 (free_numargs, parse_symbol, add_symbol, add_block,
133 shrink_linetable): Declare these fns void.
134 (upgrade_type): Convert tree of if's to switch. Clean up
135 bogus "off == 0" handling with a complaint. Avoid setting
136 field bitpos and bitsize of array with lower and upper bounds.
137 Check specified bitsize of elements against their actual type's
138 bitsize, and complain if different. Complain about unknown
140 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
141 (psymtab_to_symtab_1): Print names of subsidiary files that
142 are being read in. FIXME, we read far too many files. This code
143 is not the problem, the problem is in parse_fdr where the psymtabs
145 (cross_ref): Result should indicate that we used one aux entry
146 normally, or two if we encountered a "next" entry. This used
147 to leave the caller pointing at the wrong aux entry.
148 (add_symbol): If overflowed cur_block, reallocate it larger,
149 chase all pointers to it, and complain(), rather than clobber memory.
150 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
151 (new_field): Only allocate one field initially, not two.
152 Pull ++ out of macro argument. Simplify.
153 (_initialize_mipsread): Avoid initialization of importd
154 global_psymbols and static_psymbols.
156 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
157 to properly set pst->symtab; avoid searching for it.
158 (symfile_fns): Improve comments, add a FIXME.
159 * dbxread.c: Update comments to reflect symfile protocol.
160 (read_ofile_symtab, end_symtab): Return the symtab.
161 (psymtab_to_symtab_1): Set pst->symtab.
163 * coffread.c (coff_symfile_read): tell condense_misc_bunches
164 whether we're mainline.
166 * symfile.h (sym_fns): Remove unused sym_discard member.
167 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
169 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
170 the environment variable is not.
171 * infcmd.c (finish_command): Use filtered printfs.
172 * cplus-dem.c: Add struct tags to a few unnamed structs.
173 * valops.c (value_coerce_array): Improve comments.
174 * valprint.c (type_print_varspec_suffix): Print array size only
175 if greater than zero.
176 * m88k-tdep.c: Shift some lines left by one space, that had
177 apparently been trashed at some point.
178 * TODO: More things to do, a few got done.
180 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
182 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
183 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
185 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
186 * expread.y, findvar.c, symmisc.c: Ditto.
187 * printcmd.c (address_info): Update printed forms of LOC_
188 symbols. Elim LOC_EXTERNAL.
189 (print_frame_args): Keep track of param stack offsets before
190 re-looking up to find the local register param is kept in.
192 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
193 Further integration of mipsread into gdb. Eliminate unused
194 routines, duplicate declarations. Handle static symbols in
195 psymtabs as well as external symbols. When reading symtabs,
196 insert symbols into the correct block (global, static, or a local
198 (read_mips_symtab, parse_partial_symbols): Don't pass useless
200 (mipscoff_symfile_read): Don't call select_source_symtab.
201 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
202 rather than SYMBOL_VALUE.
203 (parse_external): Comment clobbering of top_stack.
204 (parse_partial_symbols): Update comments. Allocate and parse
205 static symbols as well as external symbols. FIXME, enum values
206 are not handled in this pass, but should be. Inline new_psymbol.
207 Use SYMBOL_VALUE_ADDRESS.
208 (psymtab_to_symtab_1): Read symbols into global static block
209 by default (until enter some function's local block context).
210 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
211 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
213 * source.c (select_source_symtab): Select a source symtab
214 from either the symtabs or, failing that, the psymtabs.
215 (list_command): Update error message.
216 (forward_search_command, reverse_search_command): Use getc, not
217 fgetc, for speed. FIXME, add comment about buffers that die if
218 overrun by long line.
220 * values.c (unpack_field_as_long, modify_field): Avoid shifting
221 by an entire word, which is not portable, if we have a 32-bit
222 field. (Code in dbxread.c already turns such bitfields, if
223 aligned, into ordinary ints, but fixing this will help for other
224 symbol formats and for future changes.)
225 * core.c (core_open): Handle ANSI const brain death.
226 * utils.c (vprintf): Fix varargs typo.
228 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
230 * findvar.c (find_var_value): Handle &function better.
231 * TODO: Document work needed on &fn and &array.
232 * printcmd.c (print_address_symbolic): New arg is the prefix
233 to print if a name is printed.
234 (print_address_demangle): Honor "set print address" now.
235 Use new arg above to improve spacing of output.
236 * valprint.c (val_print): When printing function pointers,
237 print symbolic form too.
238 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
240 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
242 * core.c (memory_error): Reword error msg to mislead less.
244 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
246 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
247 parse_partial_symbols): Use newer BFD internals (external_filehdr
248 and external_aouthdr), byte-swap the fields that we care about
249 before using them, and make the file header data local to
250 read_the_mips_symtab rather than global.
252 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
254 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
255 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
257 * main.c (command_line_input): Flush stdout and stderr
258 before every call to readline. This reportedly fixes a bug
259 that comes up in Sys V running emacs-gdb and/or xxgdb,
260 when stdin/out are pipes or sockets.
262 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
264 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
265 Avoid declaring Makefile dependencies, because GNU Make stupidly
266 tries to update it if we do.
268 * coffread.c: Revise for minor changes to bfd internal coff
271 * configure: If -template= is given a relative path, make it
272 absolute before recurring in subdirectories.
274 * configure, configure.in, Makefile.in: Install "configure" script
275 as replacement for config.gdb.
276 * config.gdb, Makefile.dist, Makefile.sdir: Remove
277 * README: Update for configure, mostly. FIXME.
279 * Add dec3100 as equivalent to littlemips. Indicate in all host &
280 target config files that they are for the host. When the lines
281 get copied into the Makefile, this makes it more obvious what's
284 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
286 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
287 tabs, which end up in the disassembler output inadvertently.
289 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
291 Make it compile cleanly in an ANSI GCC2 environment.
293 * blockframe.c: <stdio.h>
294 * cplus-dem.c: free takes a void *, ifdef __STDC__
295 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
297 * defs.h (alloca): Avoid doing anything if alloca already def'd.
298 * stddef.h, stdlib.h: Remove these files.
299 * symtab.c: Avoid declaring qsort, close.
300 * symfile.c: Avoid declaring close.
301 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
302 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
304 Assorted other changes.
305 * dbxread.c: include "libaout.h", not "liba.out.h".
306 * printcmd.c (print_frame_args): Set recurse properly for
307 indentation of struct and array parameters.
308 * valops.c (value_cast): Allow cast to void.
309 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
310 single_step() in a target-independent fashion.
311 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
312 set up to be ready to continue. This makes us target independent.
313 * infptrace.c (child_resume): Remove call to single_step; now
314 can single step a SPARC target of any kind.
316 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
318 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
319 docn into separate sections---basically chapters, plus two loose
320 pieces that can be configured to go in different places. This
321 allows GNU m4 to preprocess the manual without coredumping.
323 * Makefile.dist: tell TeX where to find texinfo.
325 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
327 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
328 the new target "rdl-apps.texinfo" which captures the Makefile
329 variable that records where to find the Readline libraries.
331 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
333 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
334 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
335 * defs.h (const, volatile): Only define if not already defined.
336 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
338 * README: Update for release 3.95.
339 * config.gdb: Don't create readline dir in subdir builds.
340 * main.c: Include with "..." form for non-system include files,
341 so "gcc -MM" for "make depend" works.
342 Include readline files with "...h" rather than <readline/...h>.
343 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
345 * coffread.c: Undo minor damage done by Rich Pixley. Use
346 different internal and external representations of COFF
347 data structures. Use new BFD routines for swapping them in and
349 * symfile.c (free_named_symtabs): Avoid freeing file names that
350 are null or empty. Old i960 tools seem to produce files that
351 claim to have empty names, causing each successive file read
352 to blow away the previous one.
353 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
354 Move deferred_stores to top of file, but don't separate its
355 #define's from its variable. Add commentary.
356 * Makefile.dist: Fix Rich damage; undo "configure" changes in
357 favor of keeping the (working) config.gdb. Move readline
360 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
362 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
364 * infptrace.c (fetch_registers): no result, since now void.
365 * tconfig/news: target depends on m68k-tdep too.
367 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
369 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
372 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
373 applied various small fixes due to or inspired by RMS comments
375 * doc/gdb.texinfo: finished using all RMS comments, save those for
376 appendices on readline and cmd history (which are in other source
379 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
381 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
382 chapter 9; (2) documented 'break' command's menu mode for
383 overloaded names, in response to hgs problem report C++ p-31
385 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
387 * doc/gdb.texinfo: (1) better introductory example; (2) more
388 consistent use of @code, @samp, @file, @kbd throughout; small
389 cleanups to first three nodes; (3) new "Contributors" node;
390 (4) Appendix, Renamed Commands; (5) divert specialized startup
391 instructions to "Targets" chapter for generic manuals, while
392 leaving them up front for manuals specific to specialized
393 environments; (6) apply fixes from RMS comments through chapter 4.
395 * pretex.m4: modify explanatory text slightly (and redefine
396 "regexp") to keep GNU m4 from complaining. (It still crashes
397 later, but one step at a time...)
399 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
401 * readline/readline.c (update_line): Avoid dereferencing a pointer
402 before comparing it to its bounds. Saber caught this.
403 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
404 and only set PC if tgetstr returned non-null. Saber caught this.
406 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
408 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
409 stuff for config manual) here where it counts; updated
410 to use new subdir structure (gdb/doc/).
412 * Makefile: generated from above via
416 * gdbint.texinfo: added instructions on generating gdb.info* files
417 locally for release. These are ordinary info
418 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
419 Makefile)---but due to use of texinfo 2, can't count on makeinfo
420 to generate these, so we distribute them already formatted.
422 * gdb.texinfo: included full Info node and menu crud (as generated
423 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
425 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
426 put in comments-for-future gdb.info target (one day makeinfo will
429 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
431 * gdb.texinfo: Updated to include new or old undocumented
432 commands, at least the following (perhaps some others I forgot to
433 record): info f, info float, info path, info program, info s, info
434 set, info source, info terminal, info types, info user, set/show
436 Also covered all recent GDB command renames for v4.
438 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
440 * mipsread.c: Rather than keeping count of how many symtabs
441 and psymtabs we have, for sorting purposes, count them when
442 we need to sort. This fixes bug in rereading of symbol tables.
444 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
446 * infcmd.c: renamed "info path" to "show paths"
447 * gdbrc.tex: documented above.
449 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
451 * remote.c: Fix comments.
452 * utils.c (error): Force out any pending wrap output.
454 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
456 * Makefile.dist: Roll VERSION to 3.95.
457 Fix up "saber_gdb" to work again.
458 * saber.suppress: Update.
460 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
461 symtab.h, target.c, target.h: Lint.
462 * core.c: setup and select frame after reading shared libs,
463 else reading shared libs will clobber them. Lint.
464 * utils.c (error): Force out any buffered wrap text.
466 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
468 * remote.c: Remove decls of memory_insert_breakpoint
469 and memory_remove_breakpoint, no longer used. (Suggestion of
472 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
473 to make it easier to interface to "configure"'d libraries.
475 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
477 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
478 aliases for set/show print.
480 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
482 * coffread.c (coff_sym_fns) [TDESC]: Make the type be m88kbcs.
484 * m88k-tdep.c (IEEE_isNAN): New function.
486 * infrun.c, m88k-tdep.c, m88k-xdep.c: Change
487 initialize_{tdesc,dcontext} to init_{tdesc,dcontext}.
489 * infrun.c [TDESC]: Add a bunch of crud.
491 * xm-88k.h [__GNUC__]: Don't define memset.
493 * m88k-xdep.c: #if 0 out push_breakpoint.
495 * tm-88k.h: Define GET_SAVED_REGISTER.
497 * tm-88k.h: Define DGUX.
499 * m88k-opcode.h (UEXT, SEXT, MAKE): Put parentheses around arguments.
501 * m88k-pinsn.c (sprint_address): Declare at top of file.
503 * m88k-xdep.c: #if 0 out core_file_command.
505 * values.c ({unpack_,value_as_}pointer): Just call

998 (_initialize_values): Rename "info directories" to "show directories".
1000 * values.c: Rename convenience_info to show_convenience.
1001 (_initialize_values): Rename "info convenience" to "show convenience".
1003 * copying.awk (_initialize_copying): Rename "info copying" to
1004 "show copying" and "info warranty" to "show warranty".
1005 Rename {copying,warranty}_info to show_{copying,warranty}.
1007 * symfile.c: Rename add_syms_command to add_symbol_file_command.
1008 (_initialize_symfile, add_syms_addr_command):
1009 Rename add-syms to add-symbol-file.
1011 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
1013 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
1014 * symfile.c (clear_symtab_users_once, cashier_psymtab,
1015 free_named_symtabs): Move these routines from symmisc.c.
1016 * symmisc.c (same): same.
1017 (free_symtab): Make non-static.
1018 * symtab.h (free_symtab): Declare as exported void fn now.
1019 * dbxread.c (end_symtab, end_psymtab): Change comments.
1020 (initialize_dbxread): Call dbx_new_init() in case the first
1021 command is add-symbols.
1022 * target.c (dummy_target): Permit add_syms_addr_command.
1024 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1026 Permit symbols to be superseded when new symbol files have
1027 been read in, particularly for VxWorks.
1029 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
1030 to the main file, as well as to include files. Also, put global
1031 functions into the global psymtab, to make "i fun" work.
1032 (end_psymtab): Free named symtabs and psymtabs for a file, once a
1033 new psymtab for it has been read.
1034 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
1035 a file, once a new symtab has been read for it.
1036 * mipsread.c: FIXME. We need to do the same for MIPS, but it
1037 looks harder to determine the top-level block before it's been
1038 queued to the psymtab list.
1040 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
1041 If we have wiped out any old symbol tables, clean up at end of
1043 (symbol_file_command): Don't reference symfile_fns if it's zero.
1045 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
1046 defines for the blocks of a blockvector that contain global and
1047 file-static symbols and the first of the smaller scope contours.
1048 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
1049 decode_line_1, make_symbol_completion_list): Use the above.
1050 * coffread.c (end_symtab, patch_opaque_types): Ditto.
1051 * dbxread.c (end_symtab): Ditto.
1052 * expread.y (block): Ditto.
1053 * mipsread.c (throughout): Ditto.
1054 * symmisc.c (free_named_symtabs): Ditto.
1056 * symtab.c (list_symbols): Process the first symbol of the
1057 static psymbols list.
1058 (types_info): Restore this function from its untimely #if 0.
1059 It's not perfect, but it is better than nothing.
1060 (_initialize_symtab): Restore "info types".
1062 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1064 * m68k-stub.c: Remote stub for 680x0's, created from
1065 rem-m68k.shar (which is removed).
1066 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
1067 Remove RCS log stuff now that we use CVS and it blows our diffs.
1069 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1071 * symmisc.c (free_named_symtab): Make it work, in its current
1072 kludgy fashion. Change result to indicate if we blew away bkpts.
1073 * dbxread.c (end_symtab): Accumulate result from
1074 free_named_symtab and print warning if we blew user's state.
1075 * symfile.h: free_named_symtab now returns an int.
1077 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1079 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
1080 is the first symbol read, even if not mainline.
1081 (dbx_psymtab_to_symtab): symfile might be zero, cope.
1082 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1083 (set_section_command): New command ("section xxx yyy" -- should
1084 be renamed to "set section xxx yyy" FIXME) which sets the
1085 base address of a section of the exec file, overriding the
1086 virtual address that BFD reports.
1088 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1090 * exec.c: Add add_syms_addr_command to exec_ops, so you can
1091 load symbols at any address while examining an exec file.
1093 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1095 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1096 for printing the float info is host-dependent, not
1097 target-dependent. FIXME.
1098 * i386-pinsn.c: Move #includes to top, remove useless ones.
1099 * i386-tdep.c: Don't bother including <.../reg.h> since we
1100 don't use it (and it doesn't exist on host systems).
1102 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1103 Convert negative numbers properly.
1104 (ieee_test): Make numbers really random; fix format arg.
1106 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1107 * core.c (core_detach): Unpush core_ops, which might not be on
1108 top. We used to just pop the top, which broke things. Don't
1109 need dont_repeat() any more.
1110 (core_file_command): Psst! Don't repeat it.
1111 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1112 * expprint.c (print_subexp): Avoid switch fallthru on
1113 BINOP_ASSIGN_MODIFY, so we can print += and such.
1114 * frame.h: Fix typo.
1115 * inflow.c (kill_command): After killing inferior, print our
1116 current frame in the core file, if we have one.
1117 (generic_mourn_inferior): When inferior dies, either select
1118 the current frame (in the new target, e.g. core file), or
1119 set both the current and selected frames to NULL.
1121 Changes from Peter Schauer.
1123 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1125 * Make all file names fit in 14 characters (sigh and damn!):
1126 mv hp300hpux-xdep.c hp300ux-xdep.c
1127 mv symmetry-xdep.c symm-xdep.c
1128 mv symmetry-tdep.c symm-tdep.c
1129 mv convex-opcode.h convx-opcode.h
1130 mv tm-vxworks960.h tm-vx960.h
1131 mv tm-vxworks68.h tm-vx68.h
1132 mv Makefile.srcdir Makefile.sdir
1133 mv gdb-int.texinfo gdbint.texinfo
1134 mv remote-sa.m68k.shar rem-m68k.shar
1135 mv remote-multi.shar rem-multi.shar
1136 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1137 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1138 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1141 * command.c (user_info_1, user_info): New command for listing
1142 the user-defined commands.
1144 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1146 * dbxread.c (really_free_pendings): Clear file_symbols
1147 and global_symbols after freeing them; otherwise, running
1148 this function twice (if it appears twice on the cleanup
1149 chain), we try to free things twice.
1151 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1152 based on text_addr (the address of text in core), not on addr (the
1153 offset between text in the .o file and in core). This change
1154 is from Peter Schauer.
1156 * main.c: Define ALL_CLEANUPS as a cast of zero.
1157 (return_to_top_level): Use it.
1158 (main): Do all cleanups after each command run as part
1159 of the gdb startup sequence. Also do all cleanups before
1160 entering the command loop, and every time we exit the command
1161 loop and reenter. Before, the cleanups from the startup sequence
1162 were being left undone until the first error!
1163 (command_loop): Rename do_nothing cleanup to command_loop_marker
1164 so we can see it easily when examining the cleanup chain.
1165 (init_signals): Add another do_nothing for signal handling.
1166 (quit_command): Only try to kill target if it has execution.
1167 Problems in the target stack got us into a state where
1168 inferior_pid was nonzero but none of the targets had execution.
1169 In this state you couldn't exit gdb.
1171 * dbxread.c: Two changes from Peter Schauer.
1172 (echo_command): Fflush output after an echo command.
1173 (show_history): Pass all args to cmd_show_list.
1175 * utils.c (init_malloc): Call mtrace to turn on tracing
1176 if the environment variable MALLOC_TRACE is set to a file name.
1177 * mtrace.c: Add source file which provides a log of every malloc,
1178 free, and realloc to a trace file.
1179 * mtrace.awk: Add source file which analyzes the trace file.
1180 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1181 (VERSION): Roll to 3.94.3.
1183 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1184 (check_duplicates): Don't bother with watchpoints.
1185 (set_raw_breakpoint): Comment about danger of this routine.
1186 (watch_command): Parse and eval all args before calling
1189 * solib.c (find_solib): Avoid error in referencing memory to
1190 see if any more shared libraries have been added. This is
1191 particularly useful if the target has terminated. Bug reported
1194 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1195 in bringing up 3.94.2 on the Sun-3.
1197 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1198 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1199 expression (in scope) before reenabling watchpoint.
1200 * signame.c (init_sigs): Add missing declaration of i, fix
1201 sys_siglist declaration.
1202 * source.c (list_command): Fixed range computation to use
1204 * stack.c (backtrace_command): Do not allow command if target has
1205 no stack, print informative error message.
1206 * target.c (target_command): Do not write into command line
1207 because this fails if the target command is used in a user defined
1208 command. [This change was enhanced by gnu to support any-
1209 unique-prefix matching on target names.]
1210 * valops.c (value_struct_elt): Avoid infinite loop on an
1211 erroneous attempt to print the member of function (try p main.p).
1213 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1215 * expread.y (name_no_typename): Avoid reduce/reduce errors
1216 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1217 Since the GDB parser really doesn't use name_no_typename in a
1218 name-only context, the parser can't tell the diff between
1219 names and numbers here. Avoid allowing a name_no_typename
1220 to be a NAME_OR_*INT to resolve the conflict.
1222 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1224 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1226 * valprint.c (val_print_fields): bitfield printing didn't handle
1227 byte order. Indirect through a few more fns to cope.
1229 * values.c (modify_field): also cope with byte order.
1231 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1233 Cleanup for release 3.94.2:
1235 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1236 include files. Roll version to 3.94.2.
1238 * coffread.c (init_stringtab): Read length into unsigned char
1239 array before swapping; don't assume 32-bit longs.
1241 * target.c (target_info): Don't bother with get_sym_file, just use
1242 the symfile global variable.
1243 * symtab.h, symfile.c (get_sym_file): Delete it.
1245 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1246 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1247 (read_type): Replace one more error() with complain().
1249 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1251 * i960-tdep.c: Fix copyright attribution.
1253 * config.gdb: Quote all backquotes in doublequotes. You can
1254 quote me on that. BSD 4.4 shell found this one.
1256 * infptrace.c (throughout): The third argument to ptrace is an
1259 * infrun.c (wait_for_inferior): When program has terminated, we
1260 have to call target_terminal_ours before we pop that target off
1261 the stack (e.g. before a call to target_kill or
1262 target_mourn_inferior). This fixes problem where a program
1263 terminates, then GDB stops for (tty output) and you have to type
1264 "fg" to the shell to resume it. FIXME: This code for what to
1265 do after termination really should be in normal_stop instead.
1267 * gdbcore.h (read_memory_check): Change declaration; it changed
1270 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1271 4.4 prereleases, this avoids a bug in their sgtty compatability
1273 * remote.c: Use terminal.h rather than hand-rolling the same.
1275 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1276 * utils.c (strsave, strstr): Fix arg types.
1277 * valprint.c (val_print): lint
1279 MIPS symbol table support from Per Bothner:
1281 * symfile.c (symtab_fns): Remove initializer table that needs to
1282 be hacked for each new symbol file format supported.
1283 (add_symtab_fns): New function, chains symbol table
1284 handlers into the global list.
1285 (symfile_init): Search this list.
1286 * symfile.h: Add next pointer, declare add_symtab_fns.
1287 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1288 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1290 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1291 symbol *). Thus, we no longer need the hack to trash
1292 pst->filename. Good, since that hack confused code in symfile.c!
1294 (reorder_symtabs, destroy_all_symtabs): Removed static
1295 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1296 Instead, the latter now uses a temporary array (stack-allocated
1297 from an obstack, and then freed).
1299 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1300 haven't been set in the outermost stBlock of a procedure. This was
1301 a problem with f77 binaries on Ultrix 4.?.
1303 (new_symtab, new_symbol, new_type): Continue changing code to use
1304 obstacks more and otherwise conform to dbxread internal style.
1305 Made the free_code of symtabs be free_linetable (as in dbxread)
1306 instead of free_contents. This implies memory leaks when reading
1307 a new symbol table, until the conversion is finished. Did change
1308 (struct symbol) and (struct type) to be allocated on the
1309 symbol_obstack. Blocks and blockvectors are among the things
1312 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1313 tested much, but it solved one problem (reported by Meissner), and
1314 cleans up some other things. The problem happened when an
1315 included file contains actual code (functions) and not just
1316 definitions. The mips coff is a little inconvenient there, since
1317 it may cause a procedure to be mapped to the wrong psymtab.
1319 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1320 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1321 this will need work for the new core paradigm.
1323 Opcode patches from the net:
1325 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1326 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1327 missing altogether - they are added here. From Bruce Bauman.
1328 * mips-opcode.h: The low mask for C0 instructions was too small.
1329 From Garrett Lau. I modified the fix to check the entire 32-bit
1332 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1335 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1337 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1339 * dbxread.c (read_type): Pointer subtraction (value_sub in
1340 valarith.c) sometimes failed because the types of the
1341 pointers being subtracted were not identical.
1342 These differed because dbxread.c was allocating pointer types
1343 using dbx_alloc_type+smash_to_pointer_type instead of
1344 lookup_pointer_type. I failed to find a justification for the
1345 former, so I changed it to use the latter. Similarly, I
1346 replaced smash_to_function_type by lookup_function_type,
1347 and smash_to_reference_type by lookup_reference_type.
1349 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1350 _initialize_mipsread): corresponding changes.
1352 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1354 * source.c (mod_path): Do tilde_expand on each component of the path,
1355 rather than on the (list of) paths as a whole.
1356 (print_source_lines): Set first_line_listed in addition to
1357 current_source_symtab and current_source_line. If the source was
1358 not findable, after a "dir" command to fix the problem,
1359 a "list" would get the wrong lines.
1361 While I was there... (gnu):
1363 * dbxread.c (read_type): Change error to complaint.
1365 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1367 First attempt at detailed understanding of symbol table memory alloc.
1369 * dbxread.c (dbx_symfile_read): Free our string table if we
1370 aren't the mainline. Free the "info" struct since we're done with
1372 (init_psymbol_list): Free any previously allocated psymbol lists.
1373 (): FIXME: Should realloc-down the psymbol lists when done reading
1374 the main symbol file?
1376 * symmisc.c (free_symtab): Free fullname field too.
1378 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1379 (REGISTER_ADDR): Make result type unsigned int.
1381 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1382 define REGEX must also define REGEX1 (its dependency).
1384 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1386 * tconfig/i960: No longer works, points you at vxworks960 or
1389 * xgdb.c, XGDB-README: Remove file. Users can get the much
1391 * Makefile.dist: Remove all trace of xgdb.
1393 * breakpoint.c (breakpoint_1): Pass demangle arg to
1394 print_address_symbolic.
1395 (clear_breakpoints): Remove unused function.
1396 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1397 (breakpoint_re_set): Use catch_errors to do them all anyway.
1399 * gdb-int.texinfo (Host versus Target): Add section on what is
1400 a "host" feature versus what is a "target" feature.
1402 * infcmd.c (path_command, path_info): Handle the PATH variable
1403 (object search path) as conveniently as the source search path.
1404 * environ.c (set_in_environ): Set some vars in GDB's environment,
1405 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1406 * source.c (mod_path): New function, from guts of
1407 directory_command, modifies a path. Used by path_command.
1408 (directory_command): Call it.
1409 * defs.h (strsave): Declare.
1411 * utils.c (sevenbit_strings): Add new printing option.
1412 (printchar): Use it.
1413 (strsave): Provide this handy helper routine.
1414 (set_width_command): Rename set_screen_width_command.
1415 (_initialize_utils): "set screen-width" => "set width";
1416 "set screen-height" => "set height"; add sevenbit-strings.
1418 * infcmd.c (do_registers_info): Print floating point registers
1419 in raw hex as well as float format, regardless of whether it is
1420 a "virtual" convertible register.
1421 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1422 regs as a double, just in case it's being used that way.
1423 * values.c (unpack_long): Comment on array/function coercion.
1424 (unpack_double): Argument is in target byte order now. For
1425 integer arguments, just call unpack_long and float the result.
1426 * m68k-tdep.c: include defs.h for "const" handling.
1427 * remote-nindy.c: Use ieee-float stuff.
1428 (nindy_fetch_registers): Unpack double regs to host double, then
1430 (nindy_store_registers): Pack extendeds to host double, flip
1431 around by misusing unpack_double, send as target double.
1433 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1434 zero, as when stopped at the first instruction of a process.
1436 * blockframe.c: Fix filename in comment (param.h => tm.h).
1437 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1438 * tm-68k.h: Fix typos.
1440 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1442 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1444 * coredep.c (fetch_core_registers): Pass end-address of register
1445 section to register_addr as expected. Don't call supply_register
1446 if we'd just pass it garbage.
1448 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1450 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1452 * target.c (push_target, target_info): Cast enums to int for < or
1455 * stack.c (print_frame_info): Identify source file & line
1456 even if we can't print it.
1458 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1460 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1462 Clean up IEEE floating point support.
1464 * ieee-float.h: New file.
1465 * ieee-float.c: Write real routines to convert between host
1466 doubles and various target IEEE extendeds.
1467 * m68k-xdep.c: Eliminate assembler code for extended floats.
1468 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,

1470 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1471 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1472 double_to_ieee_extended.
1473 * i960-tdep.c: Define ext_format_i960.
1474 * m68k-tdep.c: Define ext_format_68881.
1475 * sparc-tdep.c: Define ext_format_sparc, though unused.
1476 * Makefile.dist (HFILES): Add ieee-float.h.
1477 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1480 Obsolete the "coffstrip" program in favor of using BFD's strip.
1482 * nindy-share/coffstrip.c: Remove file.
1483 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1484 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1485 * tconfig/nindy960: Remove reference to coffstrip.o.
1487 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1489 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1491 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1492 * dbxread.c: Remove static symfile_bfd.
1493 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1495 * inftarg.c (child_detach): Pop the child_ops vector if the
1496 detach is successful.
1497 * remote-nindy.c (nindy_create_inferior): Don't push a new
1498 nindy_ops since nindy uses the same one for execution and memory
1500 * core.c (core_ops): Use child_attach and child_create_inferior
1501 rather than default attach and create_inferior functions.
1503 Handle floating point registers in core files.
1505 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1506 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1507 This version untested since BFD doesn't yet support sun3 core
1509 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1510 conventions. Fix comments and style. This version has not
1511 been compiled yet, since we have no HP inhouse.
1512 * core.c (get_core_registers): Look for two sections, ".reg"
1513 and ".reg2", and pass both to fetch_core_registers sequentially.
1515 Revise directory path yet again.
1517 * source.c (forget_cached_source_info): Not static any more.
1518 (init_source_path): New default source path is "$cdir:$cwd".
1519 (dir_command): Handle variable arguments ($cdir, $cwd).
1520 (source_info): Print "Compilation directory" rather than
1521 "Originally compiled in" to remind people of $cdir.
1522 (openp): If the path contains $cwd, use current directory.
1523 (open_source_file): If compilation directory is known, replace
1524 first $cdir in path with the compilation directory.
1525 (print_source_lines): Even if we can't print the lines, set the
1526 current symtab and line for future commands like "info source" or
1527 "breakpoint". Also, error message now contains the file name,
1528 line number, and file access error message.
1529 (_initialize_source): Fix help text to describe changes.
1530 * main.c (cd_command): Forget cached source info when we chdir.
1531 * utils.c (strstr): Add simple implementation.
1533 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1535 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1536 Byte-swap COFF symbol tables if necessary when reading them in.
1537 Use complain() to replace error message in one spot. Needs
1538 corresponding change in bfd/coff-code.h to make some symbol
1539 swapping routines non-static.
1541 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1543 Merge changes from Eirik Fuller, for UTek.
1545 * defs.h (errno): Add declaration.
1546 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
1547 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1548 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1549 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
1550 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
1551 declarations of errno.
1553 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1555 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1556 <rpc/rpc.h> and <rpc/types.h>.
1558 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1560 * i960-tdep.c (examine_prologue): Add new argument limit,
1561 which stops the scan at the end of the prologue, or at the PC.
1562 This fixes a problem where it walks down into the code for the
1563 user's statements if that code looks like function prologues.
1564 Mark Fox and I have been bouncing this code back and forth, making
1565 small changes to it. Callers changed to match.
1567 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1569 Cleanup for gdb-3.94 release final:
1571 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1572 the .c files from vx-share and nindy-share, from the various
1573 macros, since they are not found via ALLDEPFILES.
1574 (SFILES): Add tm-i960.h.
1575 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1576 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1578 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1579 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

1583 * am29k-tdep.c: Add contribution line.
1584 (examine_prologue): Cache information about function prologues in
1585 the misc-function-vector to avoid lots of references over the
1586 serial line while examining instructions.
1588 * core.c (core_close): New function made from cleanup_core.
1590 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1591 remote-vx.c, remote.c, target.c, target.h,
1592 Update target_ops vector to add attach, close, and load entries.
1593 Use add_syms_addr_command, not add_file_addr_command, for
1594 add_file. Break out close routine from existing code.
1596 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1597 they are in an obstack.
1598 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1600 (define_symbol): Add symbol type parameter; change callers;
1601 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1602 it to influence the symbol class on the i960.
1603 (define_symbol): Swap LOC_CONST's into target byte order.
1605 * exec.c (exec_close): New function.
1606 (exec_file_command): Call it.
1608 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1609 Fix byte order of frame pointer.
1610 (read_var_value): Result of 0 if var's value can't be found,
1611 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1612 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1613 (locate_var_value): Use read_var_value and use its lazy address
1614 as the location of the var's value. Lint.
1616 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1619 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1620 obsolete Intel versions in favor of vxgdb versions.
1621 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1622 code dealing with byte order of values, which Intel did in host byte
1623 order rather than gdb-4's target byte order.
1624 (i960_frame_chain_valid): Move to nindy-tdep.c.
1625 (examine_prologue, skip_prologue, frame_find_saved_regs,
1626 frame_args_address, leafproc_return, saved_pc_after_call,
1627 pop_frame): Add vxgdb versions from Mark Fox.
1628 (examine_prologue, frame_struct_result_address): Add code
1629 to deal with the saved value of G13 (struct return address
1631 (frame_args_address): Modify Mark's version to prefer the
1632 saved value over the current value in the topmost frame.
1633 Cache result in the frame info to avoid performance hair in
1635 (print_fault): Add gdb960 code for printing faults.
1636 (_initialize_i960): Actually call check_host.
1638 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1639 add stub routines. FIXME, these currently just return zero!
1641 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1642 (attach_command): Call target_attach, not target_open, now.
1644 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1645 (child_attach): Rename from child_open.
1646 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1647 don't confuse it with a zero step_resume_break_address.
1649 * inftarg.c (child_detach): Eliminate inferior_pid test.
1650 (child_files_info): Clean up message a bit.
1651 (child_ops): Use child_attach, not child_open, to attach.
1653 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1654 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1655 findvar.c to here, since it depends on the contents of the
1656 shadow_contents of breakpoints, but keep if #if 0 since it is
1659 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1662 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1663 (ptype_command, display_command): Eliminate have_inferior_p and
1664 have_core_file_p in favor of target_has_stack or
1665 target_has_execution.
1666 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1667 code for actually finding the values of arguments, though we still
1668 keep track of the maximum stack offset for use in printing unnamed
1669 arguments. Handle missing FRAME_ARGS_ADDRESS.
1671 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1672 (struct nindy_regs): Define registers passed to/from nindy.
1673 (nindy_fetch_registers, nindy_store-registers): Translate between
1674 nindy and GDB formats for the registers.
1675 (dcache_init): Statically allocate the cache, since it was being
1676 allocated by a malloc that was never freed anyway.
1677 (nindy_create_inferior): Error, not core dump, if no exec file.
1678 (nindy_before_main_loop): Use target_load, not target_add_file.
1680 * remote-vx.c (net_load): Specify large timeout for load
1681 requests. Allow user to break out with INTERRUPT.
1682 (net_break): Remove useless code, clean up. Change callers.
1683 (parse-args, skip_white_space, find_white_space): Clean up arg
1684 parsing to cope with quoted strings.
1685 (net_wait, net_quit): Never call error, just return status.
1686 (vx_read_register, vx_write_register): Cleanup status checking.
1687 #ifdef the code based on which CPU we are using (960 or 68k),
1688 FIXME, this should be completely general but it isn't yet.
1689 (vx_xfer_memory, vx_resume): Cleanup status checking.
1690 (vx_run_files_info): Improve message.
1691 (vx_load_command): Renamed from vx_add_file_command. Allow load
1693 (net_ptrace): Remove unused routine.
1694 (vx_wait): Adopt code from vxgdb960 to cope with broken
1695 connections to target machine and prompt to disconnect. Remove
1696 debug printouts. Map some EVENT_'s to SIGnals.
1697 (add_symbol_stub, vx_open): Print names of object files we found,
1698 and "ok" if we read their symbols OK. Clarify output in general.
1699 (vx_attach, vx_detach, vx_kill): Add these commands.
1700 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1701 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1702 "info files" output, and create_inferior, since we already have
1705 * stack.c (frame_info): Replace Frame_unknown with 0.
1706 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1707 (return_command): Pop until the PC matches as well as the FP,
1708 so it works even if the FP is shared with another function,
1709 as in "frameless" or "leaf" procedures.
1711 * symfile.c (load_command): renamed from add_file_target_command.
1712 (add_syms_addr_command): renamed from add_file_addr_command.
1713 (add_syms_command): Stub to call target_add_syms.
1714 (_initialize_symfile): Change command names and descriptions,
1715 add-file => add-syms, and load from alias to its own command.
1717 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1718 maybe_kill_then_create_inferior): Default for attempts to start
1719 a process, if one is already running, is to ask about killing
1720 it and retry if yes.
1721 (upstack_create_inferior): #if-0 it, strata obsolete it.
1722 (push_target, unpush_target, pop_target): to_close() a target
1723 before unstacking it.
1724 (target_info): Renamed from target_files_info.
1725 (_initialize_targets): Rename "i files" as "i target", accessible
1728 * target.h: Improve comments about the target_ vectored routines.
1730 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
1731 Convert commenting style to standard GNU style.
1732 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
1733 (SKIP_PROLOGUE): No longer a no-op.
1734 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1735 (*_REGNUM): Sort register numbers.
1736 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1737 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1738 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1739 are now 10 byte extendeds, not 8 byte doubles.
1740 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1741 for nindy versus vxworks targets. FIXME, this should possibly go
1742 in the target vector.
1743 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1744 frame_saved_regs and arg pointer with each frame.
1745 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1746 (FRAME_ARGS_ADDRESS): Use cached result.
1747 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1748 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1749 (PRINT_RAMDON_SIGNAL): Call print_fault.
1750 (POP_FRAME): Now works.
1752 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1753 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1754 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1755 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1758 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1759 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1761 * valarith.c (value_subscripted_rvalue): Avoid handling
1762 floats and doubles specially; it gave alignment errors. Lint.
1764 * valops.c (value_of_variable, value_of_this): Error if unknown
1767 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1768 to avoid alignment problems.
1769 (value_print): Handle unknown value address.
1770 (cplus_val_print): Two args are ignored; remove them. Change caller.
1771 (val_print): Use unpack_long rather than pointer-deref.
1774 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1775 to avoid alignment problems.
1776 (value_being_returned): Error if return value unknown.
1777 (set_return_value): Add bogosity warning, FIXME. *
1779 * TODO: A woman's work is never done.
1781 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1782 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1783 Add ieee-float.o to OBS.
1784 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1785 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1786 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1788 Changes to generalize the VxWorks RPC protocol slightly, to handle
1789 i960 as well as 68000.
1791 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1792 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1793 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1794 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1795 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1796 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1797 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1798 so they will move in target byte order rather than network
1799 byte order (happens to be the same).
1801 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1803 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1805 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1808 Add contribution lines to various files, showing where they
1811 * breakpoint.c (break_insn, check_break_insn_size,
1812 read_memory_nobpt): Remove to mem-break.c.
1814 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1817 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1818 entry has bad register number. This change is not
1819 tested in this release, FIXME.
1821 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1824 * value.h: Force value's contents field to be aligned to hold
1825 at least a double or a long long (if supported). This avoids
1826 doing bcopy's in and out of the contents field.
1828 (step_1): Avoid coredump under obscure circumstances when we
1831 * symtab.h (misc_info): Add field to misc function vector for
1832 any kind of cached information the target code desires. AMD
1833 29000 uses this to avoid repeating examine_function_prologue's.
1835 * coffread.c: Lint. Remove static symfile, read_section_header.
1836 core.c (have_core_file_p): Lint: remove.
1837 expprint.c (print_subexp): Lint.
1838 infptrace.c, valops.c, valprint.c: lint.
1840 Roll in changes from vxgdb-5.0.1:
1842 * symtab.h: Comment byte order of each address class. Add
1843 LOC_LOCAL_ARG for frame-relative args (960).
1844 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1845 symtab.c, symmisc.c: ditto.
1847 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1849 * remote.c (remote_resume): Error if resume with a signal.
1851 * symfile.c (prim_record_misc_function): Clear misc_info.
1852 (fill_in_vptr_fieldno): Check stub type of arg.
1854 * valops.c (value_cast): Avoid looking up names of types whose
1855 name we don't know, to prevent coredump. Sun CC produces typedef
1856 rtx and the name of *rtx is zero...
1858 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1860 Roll in changes from final AMD 29000 port (Tiemann).
1862 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
1863 for ../include/a.out.encap.h. This might not work now that BFD
1864 is separately compiled. Instead, BFD support for encap will have
1865 to translate machine type 29k into the right COFF_MAGIC.
1867 * infcmd.c: Remove references to inferior_pid that aren't used
1868 in actual ptrace calls; use target_has_execution, etc.
1869 (have_inferior_p): Remove function.
1870 (program_info): Print target info rather than "process number";
1871 avoid gratuitous messages unless from_tty.
1872 (run_stack_dummy, finish_command): Set proceed_to_finish.
1873 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
1874 main.c: Lint. Lose have_inferior_p().
1875 inferior.h (have_inferior_p): Remove, lint.
1876 (proceed_to_finish): Add flag to ask that all regs be saved
1877 by normal_stop, for the few commands that need it, speeding up
1878 serial I/O. Add comments to stop_registers.
1880 * remote-eb.c: Remove newline from breakpoint message we grep
1881 for. Never time out when running the user program.
1885 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1887 Roll in changes from vxgdb-5.0.1:
1889 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
1890 symbol in its raw form, we are processing an unlinked ".o" file.
1891 See if the target environment has assigned it an address, using
1892 target_lookup_symbol (VxWorks does), and enter it into the symtab
1895 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
1896 68k versions for a simpler version that assumes zero FP at bottom.
1897 Fixes bug of truncated stack reports.
1899 * target.h (target_lookup_symbol): Define this routine's args
1900 and result, finally.
1902 * target.c (nosymbol): Default routine for target_lookup_symbol.
1903 (target_default): Default lookup_symbol and call_function too.
1904 (files_info): Only print has_all_memory warning if a non-dummy
1907 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
1908 vx_convert_from_virtual): If target does not have floating point,
1909 zero register "values", and avoid doing cross-net conversions.
1910 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
1911 (vx_open): Rearrange code that attaches to target and reads
1912 symbols for all loaded modules, to work if some of the modules
1913 are not accessible. Add symbol_stub() and add_symbol_stub()
1914 as callbacks from catch_errors(). Allow connect attempt to be
1915 interrupted painlessly with ^C (FIXME, there are still some bugs
1916 if the interrupt happens during symbol reading.). Print
1917 final message with puts_filtered, since symbol messages are
1922 * main.c (catch_errors): Only print errstring if non-null.
1923 (command_loop): Avoid an ioctl per command to test ISATTY.
1925 * remote-vx.c (net_load): make static; avoid sophomoric msg.
1926 (vx_xfer_memory): Return correct result!
1927 (vx_files_info): Indicate whether target has float or not.
1928 (vx_lookup_symbol): Complain, not error, if target gone.
1929 (vx_open): Print "Connected" msg before disabling immediate-quit.
1930 [FIXME: lookup_symbol and vx_open changes need testing.]
1932 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
1933 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
1934 contributor lines and update copyrights to 1991.
1936 Changes from an attempted H-PUX host port:
1938 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
1939 defines PT_ATTACH and PT_DETACH but not PT_KILL.
1940 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
1941 * remote-vx.c: include <sys/time.h> for HPUX.
1942 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
1943 "core_file_command" routine to BFD regime. May not work yet.
1945 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
1947 * xgdb.c: Replace X10 version with some VJ version.
1948 (FIXME: Its copyright assignment is not on record.)
1949 * xgdb.c: Update include files to X11R4 (Xaw crud).
1950 (xgdb_display_source, create_text_widget): fix call to
1951 get_filename_and_charpos. Rewack source window stuff for X11R4
1952 (gleaned from include files, and "nm's" of binary libraries, since
1953 I had no doc available).
1954 (append_selection, append_selection_word): Disable with FIXME
1955 since R4 changed interface here.
1956 (create_buttons): Add back the old set of buttons.
1957 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
1959 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
1960 Roll VERSION to 3.94 (not yet final though).
1962 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1964 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
1965 obstack_int_grow, obstack_int_grow_fast): Eliminate
1966 cast on left of assignment, which gives MIPS cc fits and is
1969 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
1970 F_ALIAS. Use printf, not fprintf, when not passing a file
1972 (compare_opcodes): Check that identical instructions have
1973 identical opcodes, complain otherwise.
1975 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
1976 was reported by Roland McGrath.
1977 (unimp): Only match if exactly zero instruction. (Roland)
1978 (branches and traps): Generate all variations of these
1979 instructions with macros, based on a single call that defines
1980 each condition name and its binary representation.
1981 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
1983 * valprint.c (val_print_fields): Take, and use, format parameter.
1984 This means that "p/x struct" again prints the elements in the
1985 desired format. Changed callers.
1987 * stack.c (frame_info): Use filtered output, and indicate wrap
1988 points. Remove kludgy formatting designed to avoid line wrap.
1990 * utils.c (wrap_here): If the line is already full (because
1991 we had printed a long indent or long wrapped string), do an
1992 immediate newline-and-indent.
1994 * m68k-pinsn.c (print_insn_arg): Bugfix from
1995 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
1996 instruction is incorrectly disassembled as bkpt #8.
1998 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
1999 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
2000 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
2001 and then will dump core (sometimes). I traced it back to an
2002 uninitialized symfile_name in psymtab_to_symtab.
2003 (const_vol_complaint): Add quotes to message.
2004 (define_symbol): Only believe line number if gcc_compiled.
2005 Avoid allocating symbol if we will not return it.
2007 Add target strata support so that newly established targets go
2008 into their right place in the target stack (e.g. a new exec file
2009 doesn't wipe out the ability to access the running process).
2011 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2012 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2013 and initialize it properly in all the targets.
2015 * target.h: Document strata. Change return type of push_target.
2017 * target.c (nomemory): new function for dummy memory access.
2018 (tcomplain): Rename complain, now also used in symfile.c.
2019 (push_target): Push targets within strata. New return value shows
2020 whether new target is on top of stack or not. Always keep dummy
2022 (target_files_info): Ignore dummy target.
2024 * core.c (core_open): Warn user, and skip accessing file, if the
2025 core target is not the topmost target in the stack.
2026 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2029 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2030 target_ops, it doesn't belong there since we have no regs there.
2031 Change name of target from machine => memory to clarify.
2033 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2035 * Freeze version 3.93 for release.
2037 * Makefile.dist: Handle vx-share and nindy-share subdirs
2038 properly when building gdb.tar.Z.
2040 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2041 printed in various places, so I could change just one copy.
2043 * dbxread.c, coffread.c: Change references to bfd->iostream
2044 to cast to FILE *, now that BFD avoids needing types defined
2045 in other header files.
2047 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2049 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2050 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2051 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2052 (actually gcc -Wall).
2054 * dbxread.c: Remove first_global_sym, last_global_sym, since
2055 they are never referenced.
2057 * defs.h (baud_rate): Declare.
2058 main.c: Define it, and add the -b option to set it.
2060 * gdb-int.texinfo: Add text on how to define a new host or target
2061 architecture, prompted by Per Bothner's questions about MIPS
2064 * gdb.texinfo: Document "complaints". Change doc of -q since
2065 gdb no longer prints the copyright and blurb if you specify a file
2066 name to be debugged (just like Emacs). Add doc for Nindy-specific
2067 command line flags for specifying target serial port and such.
2068 Update copyright to 1991.
2070 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2071 has taken over for us the job of ripping up executable files. The
2072 crud caused Per Bothner's port to not compile.
2074 * infrun.c (normal_stop): Avoid printing "Program exited
2075 normally" if we are in batch mode. This allows a GDB which
2076 executes a program on a target system, to behave like a Unix
2077 command (input from stdin, output to stdout, no extraneous
2080 * main.c (main): Allow additional machine-dependent command line
2081 options to be specified with the ADDITIONAL_OPTIONS,
2082 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2083 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2084 processing to occur just before the main loop with
2085 BEFORE_MAIN_LOOP_HOOK.
2086 (main): If a "core file" argument is specified, and it is not a
2087 core file, try it as a process ID to attach.
2088 (symbol_completion_function): Attempt to cope with
2089 "show screen-" TAB, not very successfully. This needs more work,
2091 (batch_file): New function, returns whether we are reading
2092 commands from an interactive tty on stdin, or from somewhere else.
2093 Called by normal_stop since it doesn't get from_tty passed down
2094 to it like many commands do.
2096 * remote-nindy.c: Handle command line options for nindy
2098 (nindy_before_main_loop): Prompt user for tty name if they
2099 don't specify it before getting to the interactive command loop.
2101 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2102 and -r command line options. Also add hook before main loop
2103 to make it easy to specify a tty.
2105 * TODO: More things to do, one done.
2107 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2109 * dbxread.c: Make complaint() calls pass pointer, not struct.
2110 Add complaints about badly formatted C++ type information
2111 (const/volatile indicator, and parse errors resulting in
2112 error_type). Fix C++ virtual member fn comment.
2113 (read_struct_type): Avoid bumping pointer if we got a parse
2114 error; this prevents our walking beyond the end of a string.
2115 Terminate loop on null char as well as semicolon.
2116 (process_one_symbol): Fix the LBRAC fix so that it uses the
2117 last previous SLINE, FUN, or SO record's PC address. C++ debug
2118 symbols did not have SLINE records in a useful order compared
2119 to the LBRAC records.
2120 (define_symbol): Handle "catch" records.
2122 * symtab.c (check_stub_type): Added new complain
2123 `stub_noname_complain' and added a consistency check to
2124 keep the debugger from crashing when finishing from an
2125 exception frame. A real fix will be needed later.
2127 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2129 * infcmd.c (attach_command): Make global.
2131 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2132 but make them easy to comment out. Perhaps later they should
2133 be enabled by what CPU you configure for? FIXME.
2134 (VERSION): Roll to 3.93.
2135 (pinsn.o): Remove rule for obsolete file.
2136 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2138 Run down a problem that manifested by printing the wrong function
2139 name in stack traces of read_ofile_symtab. Turned out that the
2140 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2141 the LBRAC symbol with an address in the *data* segment, which
2142 blew our binary search through the blocks.
2144 * dbxread.c: Use the complain() facility consistently to bitch
2145 about problems in the symbol file we are reading.
2146 (finish_block): Add code to check the nesting of the blocks;
2147 complain and Procrust them to fit if wrong.
2148 (make_blockvector): Check the order of the blocks, complain
2149 [but don't cope] if wrong.
2150 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2151 symbols to be sure their PC value is greater than the last SLINE
2152 (line number) symbol we've seen, complaining and adopting the
2153 SLINE PC value if wrong.
2155 * symfile.h (struct complaint, complaint_root, complain,
2156 clear_complaints): Add.
2157 * symfile.c (complain, complaint_root, clear_complaints): Add
2158 facility to deal with non-fatal complaints and to regularize their
2160 (symbol_file_add): Clear complaint counters to allow new complaints.
2161 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2163 * dbxread.c (dbx_symfile_read): Remember the address and size
2164 of the string table for the main symbol file, so we won't read it
2166 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2167 to avoid reading the string table yet again. Lint.
2168 (throughout): Improve filtered output, including word wrap.
2169 (read_range_type): Improve Bothner's fix to handle other types too.
2171 * utils.c: Improve line wrap implementation. Handle unlimited
2172 width by making chars_per_line unsigned.
2173 (puts_filtered): New, easy, function.
2175 * defs.h (puts_filtered): add.
2177 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2178 call the identical sort_symtab_syms() in symfile.c instead.
2180 * expread.y: Suggest the `file' command rather than `symbol-file'.
2182 * command.h (enum var_types): Add zinteger for seroable
2184 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2185 nested if's into a switch.
2187 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2188 we did not stop because of a breakpoint (it must have been for
2189 some other reason, like a "stepi"), so don't print anything.
2191 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2192 doesn't include <sys/types.h>, old SunOS's require it for
2195 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2197 A test port of gdb-3.92.6 to the Sony NEWS.
2200 Don't normally link in remote- or vx stuff.
2201 Some of it doesn't compile, and it wastes space for 99% of the users.
2202 Remove reference to no-longer-used HAVE_VPRINTF.
2203 Fixed BFD_DEP typo to BFD_DIR.
2205 Fix cast in arg to bfd_h_getlong.
2206 Make char *prefix be const.
2207 Fix how certain range types are mapped into builtin unsigned int types.
2209 Remove 2 #includes. They cause errors (on Sony, at least),
2210 and aren't needed (they wern't in earlier versions).
2212 print_address_symbolic should never demangle labels
2213 (since it prints *assembler-level* labels).
2215 [This was superseded by the change to printcmd below.]
2218 Add some "volatile" return types to avoid warnings.
2219 If MISSING_VPRINTF add vprintf function and not just macro
2220 (since vprintf is used in printcmd.c).
2222 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2223 (The latter isn't grokked by some PCC-based compilers.)
2225 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2227 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2228 * nindy-share/coffstrip.c
2229 Added some forward declarations (otherwise, gcc complains
2230 about implicit extern redefined as static).
2232 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2234 Changes inspired by Per Bothner:
2235 * printcmd.c (print_address_symbolic): Take additional parameter
2236 specifying whether to demangle.
2237 (print_address): Pass in asm_demangle to control demangling.
2238 (print_address_demangle): New fn, takes explicit arg to control
2240 * utils.c: Add new vars demangle and asm_demangle, and let them
2242 (fputs_demangled): If !demangle, just print the argument.
2243 (fprint_symbol): If !demangle, just print raw symbol.
2244 * valprint.c (val_print): Call print_address_demangle rather than
2245 print_address, to cause demangling to depend on the global
2246 rather than assembler-level demangling setting.
2247 * WHATS.NEW, gdb.texinfo: Document.
2249 * main.c (show_command): Show all settings if no arg.
2250 (initialize_main): Make "info set" the same as naked "show".
2251 * command.c (cmd_show_list): Handle prefix commands in the
2252 list, and print the name of the setting as well as its English
2253 description and value.
2255 Allow gdb functions to specify where a line should wrap if it
2256 exceeds the size of a terminal line. Use it to make the output
2258 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2259 of the right size when screen width changes.
2260 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2261 (wrap_here): New fn, indicates a point in the output where we
2262 should wrap the line rather than just letting it overflow at a
2264 (fputs_filtered): Implement wrapping.
2265 (n_spaces): New fn, returns a pointer to N spaces.
2266 (print_spaces_filtered): Use n_spaces.
2267 * defs.h (n_spaces): Declare.
2268 * stack.c (print_frame_info): Wrap with 4-space indent after
2269 fn name and before filename and line number.
2270 * printcmd.c (print_frame_args): Wrap with 4-space indent
2271 before each argument name is printed.
2272 * valprint.c (value_print): Wrap with no indentation before
2274 (val_print_fields): Wrap with indentation relative to nesting
2275 level before each field name.
2276 (val_print): Wrap with nesting indentation before array elements.
2277 * command.c (do_setshow_command): Avoid extra newlines,
2278 wrap with 4-space indent around values printed, end with period.
2279 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2281 * breakpoint.c (breakpoint_1): Implement addressprint for
2282 "info breakpoints" display. Change file name and line number
2283 format to " at file:nnn" rather than " (file line nnn)".
2284 * gdb.texinfo: Document.
2287 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2289 Frozen for gdb-3.92.6 release.
2291 README, WHATS.NEW: Update for 3.92.6 release.
2293 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2294 coffread.o from configs since it is now built by default.
2295 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2296 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2297 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2298 from configs since it is now built by default.
2300 Makefile.dist: Update for release 3.92.6. Handle files that
2301 have been moved to ../include, ../getopt, or ../bfd. Add
2302 saber.suppress and tests directory. Add config.status to
2303 the release (it will say "none").
2305 coredep.c: Minor formatting fixes.
2307 These changes were made in early December but only checked in now:
2308 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2309 nindy-share/nindy.c: lint
2310 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2311 register values coming back from the target; we store values
2312 in target byte order everywhere.
2314 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2316 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2318 * valprint.c (cplus_val_print, val_print_fields): New functions,
2319 which print C++ objects. They conspire to avoid printing a
2320 virtual base class more than once, following all the twists and
2321 turns of C++ virtual base rules.
2322 (val_print): Call the above rather than do it by hand.
2324 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2325 symbol file, not for added files like shared libs. This really
2326 needs to be generalized to a timestamp per file.
2328 * core.c (cleanup_core): Avoid coredump if no core file.
2330 * config.gdb: Accept -host or -target in place of +host or
2333 * coffread.c (find_linenos): Avoid desupported BFD interface
2334 to line numbers. We still read them manually rather than using
2335 BFD's "generic" features.
2337 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2339 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2341 * Makefile.dist: Eliminate use of $< in explicit targets.
2343 * readline/Makefile: Use $< rather than $*.c, which does not
2344 include the VPATH in GNU Make.
2346 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2347 copies of tconfig/i960, added for global configuration
2348 compatability. All i960 versions can read both coff and b.out.
2350 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2351 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2354 * TODO: Think of more things to do.
2356 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2358 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2359 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2360 64-bit float conversion.
2362 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2363 equivalent to sun?os4 so global config works.
2365 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2367 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2369 * main.c: Only declare linesize once; declare pagesize not at
2370 all, since it is never used.
2371 (main): Clear newly allocated line before it is used.
2373 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2375 Further stabilization for the Intel 960.
2377 * Makefile.dist: Parameterize the location of the "include"
2378 and "bfd" directories, as well as "getopt". Add symfile.c.
2379 Link in both dbxread and coffread. Fix up "make depend" to
2380 rewack the locations of include, bfd, and getopt in its output.
2382 * README: Document moving include files, improve some of
2385 * coffread.c: Move common code out to symfile.c. Change
2386 symbol_file_command style interface to use new *_symfile_init
2387 and *_symfile_read interface under BFD. Use BFD internal
2388 info to locate line table, symbols, etc.
2390 * core.c (core_fetch_registers): Rename to get_core_registers
2391 to avoid confusion with fetch_core_registers.
2392 (register_addr): Move to coredep.c, which is already machine
2393 dependent. This leaves core.c pretty clean of dependencies.
2395 * coredep.c (register_addr): Accept this routine from core.c.
2397 * dbxread.c: Move common code (with coffread.c, etc) into new
2398 symfile.c. Each psymtab now contains a pointer to the
2399 format-dependent function that knows how to read it in. Make
2401 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2402 (process_one_symbol): Add code to complain about a "compiler bug
2403 we muzzle here", if we actually see it.
2405 * eval.c (evaluate_subexp): Insert missing "break" statements
2406 in code that determines whether a variable is an lvalue in
2407 memory, register, or whatever. I detected this via a compiler
2408 bug in which it *almost* mashed out the whole switch statement.
2410 * gdb-int.texinfo: Add minor sections on configuring gdb for
2411 release, and about the README file.
2413 * infcmd.c (registers_info): Fix formatting somewhat. Still
2414 not as pretty as before, but it handles byte swapping.
2416 * remote-nindy.c: If data cache routines are interrupted while
2417 waiting for the remote end, be sure that any uninitialized cache
2418 blocks are on the free list, not on the valid list!
2420 * symfile.h: Flesh out this header file with all the various
2421 routines and variables that have been merged in from dbxread.c
2422 coffread.c, and symtab.c to symfile.c.
2424 * symfile.c: New file, containing code common to dbxread.c,
2425 coffread.c, and some code from symtab.c. All generic code for
2426 reading symbol files should be in here now.
2427 (unrecord_misc_function): Remove unused function.
2429 * symtab.h: Remove file-reading things to symfile.h.
2431 * symtab.c: Remove file-reading things to symfile.c.
2433 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2434 to decode i960 fault types.
2436 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2437 target.c: Change type of the "resume" function from int to void,
2438 since its result was never used.
2440 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2442 * main.c: Replace "stupid" with "caution"; you now "set caution
2445 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2447 * infcmd.c (do_registers_info): Call val_print to deal with the
2448 byte order of the registers being printed. FIXME, this makes
2449 the formatting of the output uglier.
2451 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2452 defined, call it for signals the debugger doesn't itself use.
2453 The i960 uses this for more detailed fault information.
2455 * remote.c (remote_open): If arg is null, print help rather than
2458 * sparc-xdep.c (register_valid): Avoid declaring size, since
2459 various modules will think of various sizes depending on the
2460 architecture of their tm-file. FIXME, we need protection against
2461 actually entering one of those modules, which would clobber
2462 storage if not for the target architecture compiled into gdb.
2464 * stack.c (up_command, down_command): Always print the frame
2466 (up_silently_command, down_silently_command): New commands
2469 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2471 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2472 more parameters than it used to.
2474 * findvar.c (registers): Increase slop to 256 bytes, which should
2475 protect us against even most RISC machines with large register
2477 (locate_var_value): Move declaration inside related ifdef.
2479 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2480 throughout, to avoid throwing away buffered input from the board.
2481 (nindy_wait): Supply_register takes addr_of_value, not value.
2482 (i960_print_fault): Renamed from i80960_fault.
2483 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2484 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2486 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2487 we can set the PC in the call to proceed(). Unpush nindy_ops
2488 before pushing it on top, to avoid message to user. Eliminate
2489 commentary from Unix machines that just misleads here.
2490 (reset_command): Fix error message to suggest target command.
2492 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2494 Release 3.92.5 as frozen.
2496 Stabilize the merged release...with help from lint, Saber C,
2499 Everywhere: Add include files needed to declare return types
2500 of functions called.
2502 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2504 * breakpoint.h: Add undeclared breakpoint functions, and some
2505 functions for display handling since I couldn't think of a better
2508 * breakpoint.c (insert_breakpoints): Make code for disabling
2509 shared library bkpts more likely to work. It's used when we
2510 rerun a program and stop before the shared library has been
2512 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2513 cast from pointer, so it squeezes through catch_errors.
2514 (bpstat_stop_status): Fix logic broken some time ago. We now
2515 always create a bpstat if the stop address matches a breakpoint,
2516 even if we don't stop there -- just like the old code used to do
2517 before I got my fingers into it (sigh).
2518 (breakpoint_1): Print "ignore count" after "stop only if"
2519 condition, since that's how it actually works.
2520 (mention): Handle watchpoints as well as breakpoints.
2521 (watch_command): use set_raw_breakpoint and mention to do most
2522 of the work (and initialize all the fields!). Only pass one
2523 arg to parse_c_expression, since that's all it takes.
2525 * command.c (not_just_help_class_command): Rename arg to args
2526 since we ignore "unused argument" warnings on vars named "args".
2527 inflow.c (child_terminal_info): ditto.
2528 infptrace.c (kill_inferior): ditto
2529 main.c (catch_errors, version_info, quit_command, pwd_command,
2530 source_command, dump_me_command, editing_info,
2531 set_history_size_command, set_history, show_history,
2533 stack.c (locals_info): ditto
2534 target.c (target_files_info): ditto
2535 valprint.c (set_input_radix, set_output_radix): ditto
2537 * core.c: Remove old variables for handling core and exec file
2538 sections (data_start, data_end, stack_start, stack_end,
2539 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2540 text_end, exec_data_start, exec_data_end, text_offset,
2541 exec_data_offset, data_offset, stack_offset). They're
2542 superseded the more general build_section_table and
2544 (get_exec_file): Mention the `file' command.
2545 (read_memory_check): Rename to memory_error, and only call it
2546 in the case of an actual error.
2547 (read_memory, write_memory): call memory_error.
2548 (core_fetch_registers): Register section name is ".reg".
2550 coredep.c: Remove a bunch of crud now that all this file does
2551 is pull the registers out of a core file.
2552 (fetch_core_registers): Rewrite to actually work, I hope.
2554 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2555 Replace index() with strchr(). Remove all the pre-BFD macro
2556 definitions for accessing the symbol file.
2557 (struct dbx_symfile_info): Encapsulate the information that
2558 dbx_symfile_init needs to pass to dbx_symfile_read in this
2561 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2562 dbx_symfile_discard): Rearrange symbol file reading to divide
2563 the format-specific part from the format-independent part,
2564 leaving the format-independent part such as file name expansion
2565 and opening in symtab.c. This replaces
2566 partial_symbol_file_open and partial_symbol_file_read.
2567 Symbol_file_read, add_file, add_file_target_command,
2568 add_file_addr_command move to symtab.c. Pass an explicit
2569 "mainline" flag for when reading the main symbol table, rather
2570 than relying on the offset address to be zero or nonzero.
2572 (dbx_symfile_read): Don't allow void *'s to be printed as
2574 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2575 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2576 macro" debug version really work.
2577 (read_dbx_symtab): Remove unref'd parameter inclink.
2578 Avoid swapping N_SLINE symbols, for speed.
2579 Merge N_TEXT!N_EXT case with the other external symbol
2580 definitions' case. Add comments.
2581 (start_psymtab): Allocate the symfile name in the psymtab on
2582 the psymbol_obstack, rather than using the caller's storage.
2583 (end_psymtab): Only allocate a dependencies list if there are
2585 (psymtab_to_symtab_2): Use BFD when reopening file to read
2586 its symbols for real.
2587 (read_struct_type): Add FIXME comments where it needs work
2589 (read_huge_number): Add FIXME about overflows.
2590 (read_range_type): Add FIXME about comparing a long to 1<<32.
2592 * coffread.c: Minor changes to move things closer to the new
2593 regime with symtab.c and dbxread.c Major work is still needed
2596 * exec.c (exec_file_command): Remove old variables (see core.c
2598 (xfer_memory): If memory transfer is right at the end of a
2599 section, don't lose.
2601 * findvar.c (get_saved_register): If value is in a real
2602 register, LVAL is lval_register, not lval_memory.
2604 frame.h: Declare print_sel_frame and record_selected_frame.
2606 gdb-int.texinfo: New file, for GDB internals documentation.
2607 Very simple, unformatted doc of cleanups is there for now.
2609 gdbcore.h: Remove obsolete variables that described a.out
2610 section addresses and offsets. (See core.c above.)
2611 Declare fetch_core_registers and registers_fetched.
2613 getopt.c: Declare char *alloca(); even on SPARC.
2615 infcmd.c (run_command): Call target_kill rather than
2617 (step_command, next_command, stepi_command, nexti_command):
2618 Declare from_tty parameter even though we don't use it.
2619 (run_stack_dummy): argument BUFFER is a char array, not
2620 a pointer to REGISTER_TYPE.
2621 (finish_command): using_struct_return needed a value *,
2622 not a struct symbol *.
2624 * infptrace.c (child_xfer_memory): To avoid dependency on
2625 where sections are in memory, try PT_WRITE_D and if that fails,
2626 try PT_WRITE_I. Most Unixes don't care which you use.
2628 * infrun.c (step_resume_break_shadow): Change to array to
2629 match other breakpoint shadow storage.
2630 (clear_proceed_status): Pass address of bpstat to
2631 bpstat_clear, not the bpstat itself.
2632 (child_create_inferior): FIXME comment about if the child
2634 (start_inferior): Remove old function.
2635 (child_open): Use target_kill rather than kill_inferior.
2636 (wait_for_inferior): Ditto.
2637 (insert_step_breakpoint, remote_step_breakpoint): Use
2638 new step_resume_break_shadow.
2640 * inftarg.c (child_wait): If all child processes die,
2641 pretend that the one being waited for exited with signal 42.
2643 * main.c (command_line_input): When scanning for comments,
2644 don't coredump on unclosed quotes.
2645 (quit_command): Use target_kill rther than kill_inferior.
2646 (_initialize_main): Rename class_user from "user" to
2649 * printcmd.c (print_command_1): Initialize "fmt" if no format
2650 is specified by the user.
2651 (print_frame_args): Only add to args_printed if we are
2652 actually fetching args from the stack (avoiding undefined
2654 (_initialize_printcmd): Remove bogus \{ from string.
2656 * remote-eb.c (eb_open): Avoid coredump on no argument.
2658 * remote-nindy.c: Bring out of Intel environment into new
2659 target environment. Remove all conditional compilation on
2660 I80960. Massive hacking throughout.
2661 (nindy_xfer_inferior_memory): New routine stolen from
2663 (nindy_create_inferior): New routine pieced together, probably
2664 not quite working yet.
2665 (nindy_ops): New target_ops struct for nindy.
2667 * remote-vx.c: Use write_memory rather than target_write_memory
2668 to get error checking.
2669 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2671 (vx_create_inferior): Use target_terminal_ours...
2673 * signame.c (_initialize_signame): Always initialize, since
2674 we need the table for things other than psignal.
2676 * solib.c (solib_add): Use symbol_file_add, not add_file.
2677 (solib_address): Return boolean result rather than struct
2678 pointer which nobody else knows the type of.
2680 * sparc-tdep.c, valops.c: Use write_memory rather than
2681 target_write_memory, to get error checking.
2683 * stack.c (locals_info, catch_info, args_info,
2684 get_selected_block, frame_command, up_command): Use
2685 target_has_stack, rather than have_inferior_p or
2688 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2690 * symfile.h: New file, defining the interface between the
2691 generic and object-file-specific symbol reading code.
2693 * symtab.c: Move generic symbol-reading interface to symtab.c,
2694 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2695 table to map BFD targets to symbol-reading modules in GDB.
2696 Change index to strchr.
2697 (lookup_struct_elt_type): Use error() rather than hand-made
2698 simulations thereof.
2699 (lookup_partial_symbol): Speedup slightly when length == 0.
2700 (symbol_file_add): New function.
2701 (symbol_file_command): Call it.
2702 (symfile_open, symfile_init): New function.
2703 (add_file_target_command, add_file_addr_command): moved from
2706 * target.c (target_command): use target_kill.
2708 * target.h (target_files_info): Don't declare, never called
2711 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2712 files to determine stack end address.
2714 * valarith.c (value_x_binop, value_x_unop): Change error message
2715 to be more useful. Pass proper argument to value_struct_elt.
2717 * valops.c (value_assign): FIXME comment that long long
2718 bitfields will break here.
2720 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2721 Update `make saber_gdb' to work better.
2723 * TODO: A woman's work is never done.
2725 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2726 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2727 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2728 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2729 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2730 valops.c, valprint.c, exec.c: Lint.
2733 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2735 Continuing Intel 960 port merge of GDB.
2737 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2738 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2739 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2740 Wack over "make depend" so it handles files in subdirectories
2741 vx-share, nindy-share, bfd, and in the current directory.
2743 * blockframe.c (get_prev_frame_info): Remove fatal error
2744 if stack not defined.
2746 * core.c (core_open, core_detach): New functions that handle
2747 the old "core-file" command as "target core" and "detach" instead.
2748 (core_file_command): Call them.
2749 (core_xfer_memory): Use common routine xfer_memory.
2751 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2752 dbxread now uses bfd for everything but symbol reading itself.
2753 BFD internals are used to drag out the relevant file offsets.
2754 (partial_symbol_file_open): Change args all around for BFD.
2756 * symtab.c: Rename "value" to "val" everywhere, so we can
2758 (symbol_file_command): New command, moved from dbxread.c
2759 and coffread.c. It uses BFD to read the file, then vectors
2760 based on its type, to dbx or coff symbol readers.
2761 * symtab.h: Extern a few vars for symbol_file_command.
2763 * target.h: Breakpoint takes a char * save area, not a char **.
2765 * valprint.c (val_print): When unpacking bitfields, offset
2766 the address in gdb of the value, if it is declared with a shorter
2767 type. Remove the last "runtime kludge test" of host byte order.
2769 * utils.c: Remove old my_bfd_read routine.
2771 * stack.c (frame_info): Use target_has_stack. Print program counter
2772 register's actual name rather than "pc", since it's called the
2773 "ip" (instruction pointer) on the i960 (sigh).
2775 * target.c (target_command): Add command for selecting a target
2776 type and calling its open routine. This is used for initiating
2777 communication with a particular target, in a generic way.
2779 * tm-i960.h: Update for modern gdb. Remove semicolons from
2780 various macros. Handle reading struct return convention, and
2781 error-out attempts to return structs with the "return" command.
2782 Be sure gdb doesn't think we know how to call functions in the
2785 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2786 to i960_xxx in lower case.
2787 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2788 not being defined yet.
2790 * remote.c (remote_open): Call start_remote to initialize
2791 wait_for_inferior during open.
2792 (remote_xfer_inferior_memory): Return length written rather
2795 * remote-vx.c (target_command -> vx_open): Use new generic
2797 * remote-eb.c, inftarg.c, exec.c: ditto.
2799 * infrun.c: Fix comments.
2800 (attach_program -> child_open): Use new generic target command.
2801 (wait_for_inferior): Clear saved register values before target_wait,
2802 so target_wait can set some of them if convenient.
2804 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2805 Return success indicator, not void.
2806 (child_xfer_memory): Avoid fetching initial word if we'll
2807 overwrite it anyway.
2809 * infcmd.c (attach_command): Use new generic target open routine.
2810 (_initialize_infcmd): Update doc on attach and detach commands.
2811 (do_registers_info): Merge in a byte-order problem as a FIXME
2814 * findvar.c (find_saved_register): Avoid problem in current frame.
2815 (read_relative_register): Ditto.
2816 (write_register): Convert byte order on the way out.
2818 * exec.c (file_command): Add.
2819 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
2820 (xfer_memory): Common function between core_xfer_memory and
2822 (exec_xfer_memory): Use it.
2824 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
2826 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
2827 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
2828 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
2830 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
2832 Merge Intel 960 port of gdb, continuing...
2834 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
2835 symbol_file_command): Pass from_tty arg to hush 'em up.
2837 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
2838 Add magic numbers for 960 COFF format.
2840 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
2842 Merge Intel 960 port of gdb, from Intel "1.2" release.
2844 CHANGE_LOG entries from their port, which was based on
2847 Thu Sep 6 11:02:22 PDT 1990
2848 Remove temp file if download is interrupted.
2850 Wed Aug 1 09:08:33 PDT 1990
2851 Now uses binary protocol to talk to NINDY.
2852 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
2853 Times out after 5 seconds when trying to talk to NINDY.
2855 Tue May 29 12:54:49 PDT 1990
2856 Added variable baud rate (-b switch).
2857 Source code reorganization.
2859 Thu Apr 26 11:09:55 PDT 1990
2860 More cleanup of batch mode; specifically, execute "-s", "-e", and
2861 "-se" switches as soon as they are encountered on the invocation line.
2863 Fri Apr 20 13:47:15 PDT 1990
2866 Thu Apr 19 09:54:28 PDT 1990
2867 Add 'reset' command.
2869 Wed Apr 18 09:48:07 PDT 1990
2870 After opening remote tty, wait for 1 second to go by without input
2871 from it before trying to talk to NINDY (fixes problems with the
2872 Heurikon HK80/V960E).
2874 Mon Apr 4 16:33:05 PDT 1990
2875 Some output was not being suppressed in 'batch' mode.
2877 Thu Mar 22 15:31:11 PST 1990
2878 Ask user if old symbol table should be deleted when new file is
2881 Allow user to run a program downloaded before gdb960 was brought up.
2883 Correct "exec-file" help message for i80960 context.
2885 Correct bug in calculating user space address: could occasionally
2886 corrupt user program.
2888 Make sure to zero low-order bits in rip's because of bug in 960CA
2889 A-step part: could cause operation faults when "next"ing across
2892 Correct bug that made it impossible to get source line numbers for
2893 code loaded at addresses higher than 0x7fffffff.
2895 Wed Jan 10 12:43:22 PST 1990
2896 Open remote tty for exclusive use.
2898 Fri Jan 5 12:14:42 PST 1990
2899 Correct disassembly (CA manual was right after all):
2900 opcode for sysctl is 0x659
2902 Mon Oct 23 12:03:04 PDT 1989
2903 Use G960BASE and G960BIN environment variables to find 'sx' utility.
2905 Mon Oct 16 14:15:09 PDT 1989
2906 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
2908 Mon Oct 2 15:56:31 PDT 1989
2910 Added 960CA disassembly support.
2912 To simplify maintenance:
2913 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
2915 - eliminated opcode.h: incorporates tables into i960-pinsn.c
2916 - moved 960-specific routines from i960-pinsn.c to i960-md.c
2917 - made disassembly interface identical to that in gdmp960.
2921 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
2923 * target.h: Allow targets to stack. Add target_has_memory,
2924 _registers, etc. Restructure memory access and "info files"
2925 to walk the target stack.
2926 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
2927 target.c: Change tables to match target.h.
2928 * inflow.c (child_mourn_inferior): pop child_ops.
2929 (generic_mourn_inferior): Use new has_stack flag.
2930 * infptrace.c (child_xfer_memory): New memory regime.
2931 * inftarg.c (child_files_info): New "info files" regime.
2932 * remote-eb.c: New memory regime, new info files.
2933 * remote-vx.c: New memory regime, new info files. Now use
2934 separate targets for VxWorks attachment to machine, and
2935 actually running a process under VxWorks, since one has
2936 stack & execution & regs and the other doesn't.
2937 * remote.c: New memory regime, new info files.
2938 * sparc-xdep.c (fetch_core-registers): New memory regime.
2939 * target.c: New routines and support for stacked targets,
2940 new memory regime, new info files regime.
2943 Generalize section handling for an arbitrary number of sections,
2944 including use of the new BFD (binary file) library.
2945 * gdbcore.h: Add struct section_table.
2946 * exec.c (build_section_table): Iterate all sections and
2947 record what gdb needs to know about them.
2948 (exec_command): Use it.
2949 (exec_xfer_memory): Use the table.
2950 (exec_files_info): Print the table.
2951 * core.c (core_file_command, core_xfer_memory, core_files_info):
2953 * source.c (find_source_lines): Use bfd_get_mtime.
2954 * dbxread.c: Quick changes to make it compile with new BFD.
2955 * utils.c (error): Avoid using bfd_error in generic routines.
2957 * core.c (core_fetch_registers): Get from the ".regs" section of
2959 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
2961 * inferior.h (attach_flag): Export.
2962 * infcmd.c (run_command): use new target_create_inferior.
2963 * infrun.c (child_create_inferior): Don't return result.
2964 * Makefile.dist (VERSION): 3.91.4.
2966 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
2968 * breakpoint.c (bpstat_num): Handle breakpoints which have
2969 since been deleted, such as temporary breakpoints.
2970 infcmd.c (program_info): ditto.
2972 * core.c (core_file_command): Display the frame where the core
2977 * remote-vx.c (target_command): Merge in target command from
2978 targ-vx.c. A few other cleanups.
2980 * TODO, Projects: Lots more stuff to do...
2982 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
2984 Massive changes to wall off the remote-debugging interface
2985 behind a function vector. The port to handle VxWorks targets
2986 is also part of this.
2988 All files: Replace references to renamed functions,
2989 remove references to remote_debugging, remove references to
2990 have_include_file, have_core_file in favor of target_has_stack,
2991 target_has_memory, etc.
2993 * Modularize the breakpoint interface.
2994 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
2995 a breakpoint instruction.
2996 breakpoint.c: struct breakpoint's shadow_contents now sized as
2998 (insert_breakpoints): Vector to target to install breakpoints.
2999 (remove_breakpoints): Vector to target here too.
3000 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
3001 sparc-tdep.c (single_step): Use new breakpoint interface for
3002 the single-step breakpoints.
3003 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
3004 New file, contains routines to insert and remove breakpoints by
3005 reading out the old contents and later replacing them. This is
3006 how ptrace breakpoints work, and many remote systems as well.
3008 * tm-vxworks68.h: New config file, overrides a few things for
3009 Wind River's preferences.
3011 * target.h: New file, for transfer vector used to talk to the
3012 inferior (child, attached, core, exec, remote, etc). All accesses
3013 to the thing being debugged should come through these vectors.
3014 target.c: New file, routines to handle transfer vector.
3015 (various files): Add transfer vectors XXX_ops for the various
3016 targets and pseudo-targets (core files, etc) we support.
3018 * breakpoint.c (bpstat_stop_status): Further explorations of
3019 watchpoints and why things don't work all the time.
3020 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3022 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3023 the local gdbinit if it doesn't already have it.
3025 * core.c (core_ops): add and install.
3026 Allow core debugging without exec file.
3028 * dbxread.c (free_and_init_header_files): Merge two fns.
3029 (end_symtab): Free named symbol table when a new version comes in.
3030 (read_dbx_symtab): Relocate all kinds of symbols with base
3031 address. First step toward handling different text, data, bss
3033 (add_file_addr_command): Renamed add_file_command.
3034 (add_file_command): Vector to remote handler.
3035 Add "load" as an alias for "add-file" command.
3037 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3038 non-returning functions.
3040 * exec.c: Add exec_ops, and push it as a target when an exec
3043 * infcmd.c (run_command): Pass executable file name and arg list
3044 separately when starting an inferior. Permit "run" when no exec
3045 file is specified, for VxWorks.
3046 (detach_command): Move to child_detach in inftarg.c.
3048 * inftarg.c: New file. Unix-child-specific routines, and the
3049 child_ops structure.
3051 * inferior.h (registers): Export "registers" as the way for
3052 target dependent register handlers to find gdb's local copy of
3053 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3054 since it is now used by places that want wait_for_inferior to
3055 handle the grunge but want to see every trap from the inferior.
3057 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3058 Eliminate remote_debugging hooks in terminal handling.
3060 * infrun.c: Replace start_inferior with child_create_inferior.
3061 Move all the hair of Unix shells and ptrace idiosyncracies into
3062 child_create_inferior, so remote handlers don't have to deal.
3063 Remove running_in_shell. Rename stop_after_attach to
3064 stop_soon_quietly, and use it in a few other places where we want
3065 to just call wait_for_inferior and get control back on the first
3066 trap. trap_expected now never takes a value > 1.
3067 (init_wait_for_inferior): Initialize static vars when a new
3070 main.c (gdbinit): Add new hook for .gdbinit file name, let
3071 it be overridden by config files as GDBINIT_FILENAME.
3072 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3073 Both of these are used for VxWorks gdb.
3075 mcheck.c: rename include file "gmalloc.c" to avoid problems
3076 with system include file "malloc.c".
3078 param-no-tm.h: New include file, same as param.h but does not
3079 include the default "tm.h" file. This is used in files where
3080 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3082 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3084 remote-vx.c: New file, VxWorks remote debugging support. Uses
3085 RPC routines that are shared with the target system, in directory
3088 remote.c: Vectorize remote interface.
3090 source.c: Globalize source_path, and make an alias "l" for "list"
3091 since we now have the "load" command.
3093 sparc-xdep.c: Use new param-no-tm.h.
3095 symmisc.c (free_named_symtab): Add new function from Wind River.
3096 However, ifdef it out for now while we think about what it should
3099 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3101 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3102 non-Unix-children handle this with their own code in the target
3105 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3106 source and target lists. Add vx-share to default list of include
3107 directories. Add new files to src and target lists: mem-break,
3108 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3109 ${srcdir} versions of munch and createtags are used.
3111 * valops.c (find_function_addr): Split out of call_function.
3112 (call_function_by_hand): Rename call_function; this function
3113 calls functions in the target by laboriously patching the target
3114 word-by-word with the right stack, args, regs, etc.
3117 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3119 Handle AMD 29000 a bit better.
3121 * remote-eb.c (readchar): Mask received char log to make it readable.
3122 (remote_start): Pass arguments down to executing program.
3123 Make startaddr unsigned.
3124 infrun.c (start_inferior): Accept args, pass them to
3126 infcmd.c (run_command): Pass args down to start_inferior.
3128 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3129 the target object file format.
3130 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3132 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3133 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3135 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3137 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3138 * TODO: We did a few things, we have more to do though.
3140 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3141 * inflow.c (inferior_died): Clear deferred stores.
3143 * Debug problems with dummy frames and calls to the inferior.
3144 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
3145 * sparc-tdep.c (do_restore_insn): Simplify.
3146 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3147 (sparc_push_dummy_frame): Simplify and fix what we push.
3148 (sparc_pop_frame): Slightly more hair here, deciding whether
3149 we are restoring a saved PC or returning to a return address in %i7.
3150 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3152 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3153 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3154 * obstack.h (chunkfun): ditto.
3155 * defs.h (xmalloc, xrealloc): ditto
3157 * utils.c (quit): Grab the terminal from the child if necessary.
3159 * inflow.c (term_status_command): Rename to term_info, change
3162 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3163 (is_delayed_branch): Speed up.
3164 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3165 Still missing some float ops, and needs testing.
3167 * Support for input and output radixes other than base 10
3168 * defs.h (input_radix, output_radix): Declare.
3169 * expread.y (yyparse, parse_number): Handle changes of input
3170 radix, and ambiguous names-or-numbers in radixes >10.
3171 * printcmd.c (print_scalar_formatted): Print formatted hex
3172 numbers in varying column widths.
3173 * valprint.c (val_print): Use output_format to print scalar ints.
3174 (set_input_radix, set_output_radix, set_radix): Create.
3175 (set_output_radix): Set output_format from output_radix.
3176 (_initialize_valprint): add `set radix' but leave the others off.
3178 * main.c (execute_command): Let stupid questions be turned off.
3179 (_initialize_main): Handle "set stupidity", etc.
3181 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3182 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3184 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3186 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3187 bfd stuff is still screwed up, but with some manual work, it
3190 * breakpoint.c (bpstat_do_actions): Start over if a command
3191 proceeds the inferior, since the inferior will have stopped and
3192 will need to have its new stop-actions taken care of.
3194 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3195 compiler fits, simplify it.
3197 * gdb.texinfo (directory command): Doc new dir command.
3198 source.c (directory_command): "dir" now puts things on the front
3199 of the path, moves dups up front, and handles multiple names
3200 on the command line, inserting each one in order. It also
3201 blows away cached line and full_filename info.
3203 * stack.c (backtrace_command): Skip "more stack frames follow"
3206 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3207 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3208 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3209 The only odd one was Gould NP1, which had defined vprintf to
3212 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3213 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3214 variable, inspect_it.
3215 valprint.c (print_string, val_print): Use the global inspect_it
3216 to indicate whether to print in Epoch style or normal style.
3218 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3220 * printcmd.c (call_command): add an alias for the "print" command
3221 which runs expressions and doesn't print the result if void.
3222 (print_command_1): implement it.
3224 * command.c: Remove #if 0'd code. Initialize all the fields
3225 in add_cmd (). Rename do_nothing_command to
3226 not_just_help_class_command, and make it externally visible.
3227 command.h: add user_commands to struct.
3228 * main.c (define_command): Don't overload c->function with a char
3229 string as well as a function pointer.
3231 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3232 calling convention of value_struct_elt () that got dropped in
3235 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3236 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3238 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3240 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3241 until a good time (e.g. when we are about to run the child),
3242 saving ptrace calls.
3243 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3244 * tm-sparc.h: define DO_DEFERRED_STORES.
3246 * sparc-xdep.c (store_inferior_registers): when storing float
3247 registers, don't store stack regs too. When storing the SP,
3248 however, DO store the stack regs too. This fixes a bug in which
3249 the dummy frame is not recognized when a call_function finishes,
3250 because its frame pointer (in the stack regs) was never
3252 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3253 even though we don't know how to read them from an inferior.
3254 valops.c (call_function): Comment about storing SP.
3256 * infrun.c (save_inferior_status): Save away the original bpstat
3257 chain so it can be restored later. Install the copied version for
3258 use by whoever saved the status. It will be blow away by
3259 restore_inferior_status, and the original chain restored. This is
3260 important for people who have pointers into the original.
3262 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3263 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3264 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3267 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3269 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3270 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3271 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3273 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3275 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3276 Store the baseclasses in a type struct starting from array element
3277 0 rather than from the unusual array element 1.
3279 dbxread.c: the above.
3280 (virtual_context): Add
3281 Read new debug information about which virtual function table
3282 a virtual function is from, and store it in fn_field.fcontext.
3284 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3285 TYPE_FN_FIELD_STATIC_P.
3287 symtab.c: the above.
3288 valops.c: the above. Handle pointer casts of object *'s.
3289 (search_struct_method): Add.
3290 (value_struct_elt): First arg is now a pointer to a value, and is
3293 valprint.c: the above.
3294 values.c (value_virtual_fn_field): Add type arg. Handle
3295 offsetting to the proper object when calling virtual fns.
3297 (baseclass_addr): Add valuep arg.
3299 * README: Document the current state of BFD config (missing).
3300 * TODO, ChangeLog, Makefile.dist: Roll version.
3301 * WHATS.NEW: Add summary of changes since 3.5.
3303 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3305 * dbxread.c (read_struct_type): Clear bit vectors whenever
3307 symtab.c (B_CLRALL): define.
3309 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3310 using == rather than =. Huh... This fixes the dreaded problem
3311 wherein builtin_type_int becomes TYPE_CODE_FLT.
3313 * core.c (info_files): Show the inferior pid.
3315 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3316 already knows how to look in the source directory.
3318 * Remove psymtab hair from many places. Remove duplicated code
3319 for searching symbol tables. Hide psymtabs from most places.
3320 Make it fast to get from a psymtab to its symtab.
3322 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3323 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3324 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3325 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3326 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3327 new symtab completely. New psymtabs get symtab pointer
3328 initialized to zero. Remove MI warning printf.
3329 symtab.h: Comments. Add psymtab to symtab pointer.
3330 (PSYMTAB_TO_SYMTAB): New macro.
3331 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3332 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3334 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3336 (print_frame_info): Avoid special-casing symbols that have not yet
3339 * source.c (open_source_file): Quick path if we have already
3340 located the source file by its full name.
3342 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3343 find_pc_psymtab. When a name is found in the misc function
3344 vector, search the symbol table for its mangled name, not the
3345 name that the user typed.
3347 * bfd.h: Fix missing comment terminators, make #endifs match.
3349 * valarith.c (value_less): Handle unsigned int comparisons.
3350 Add FIXME about pointer compares, which assume host and target
3351 pointers are the same.
3353 * command.c (do_nothing_command): lint
3354 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3355 fix comments on debug symbol format for visibility. Actually set
3356 visibility of symbols.
3357 main.c (echo_command): lint; use <readline/history.h>.
3358 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3359 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3360 pointing past end of allocated memory; saber complains.
3361 obstack.h: Declare the external functions that we use.
3362 valarith.h: use <string.h>
3363 solib.c (solib_add): lint.
3365 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3367 * main.c (initialize_main): Default info_verbose to off, now that
3368 symbol reading is fast.
3369 (quit_command): Avoid clobbering exec_bfd while quitting.
3371 * Initial BFD (binary file diddling library) merger:
3372 coffread.c: Change AOUTHDR to struct exe_hdr.
3374 core.c: initialize initialized data at compile time.
3375 (core_file_command): Move from coredep.c, convert to bfd.
3376 (xfer_core_file): Convert to bfd.
3377 exec.c (exec_file_command): use bfd routines.
3379 mips-tdep.c: Remove exec_file_command and friends.
3382 * coredep.c: (fetch_core_registers) Convert core_file_command to
3383 fetch_core_registers.
3384 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3386 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3387 (my_bfd_read): More bogosity, which I don't think we call.
3388 (program_name): Remove this atrocity asap!
3390 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3393 values.c: allocate_repeat_value was not clearing the
3394 optimized_out field.
3395 (value_static_field): minor stylistic fix (wrong macro was used).
3396 valops.c (value_struct_elt_for_address): didn't work for C++
3399 * signame.c (_initialize_signame): Initialize signal names once.
3401 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3402 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3403 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3405 * remote-eb.c: Support user-settable baud rates on the serial port.
3407 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3409 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3411 * tconfig/sun3os4: Remove warning about native assembler,
3412 since it also occurs in the xconfig file.
3414 * findvar.c (registers): Allocate some slop after `registers'
3415 to prevent stray accesses from trashing the next variable.
3417 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3418 on the sun-3, by changing the #ifdef from `sun3' (which is not
3419 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3420 vars, which happened to follow `registers' in the executable.
3422 * readline/history.c (history_search): Heed gcc-2's advice
3423 and parenthesize && inside ||).
3425 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3426 tm-29k.c: Insert FSF copyright headers.
3428 * remote-eb.c: Better comments.
3430 * Makefile.dist: Update to 3.91.6.
3431 * TODO: note PREPARE_TO_STORE problem.
3433 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3435 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3437 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3439 * infrun.c (wait_for_inferior, at end): Don't set up
3440 prev_* if the inferior no longer exists.
3442 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3443 CANNOT_EXECUTE_STACK.
3444 valops.c (call_function): Use it.
3446 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3448 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3449 infrun.c (wait_for_inferior, 2 places): Use it.
3451 * values.c (value_being_returned): Only use
3452 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3454 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3455 right thing for remote-eb.c.
3457 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3458 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3460 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3461 (FRAME_FIND_SAVED_REGS).
3463 * findvar.c ({fetch,store}_registers): Check for
3464 REMOTE_{FETCH_STORE}_REGISTER macro.
3466 * findvar.c (get_saved_register): Add argument lval and
3467 change meaning of argument addr.
3468 findvar.c: Change calls to get_saved_register to reflect
3469 new calling convention.
3470 valops.c (value_assign): Use get_saved_register instead of
3471 find_saved_register.
3473 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3475 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3476 an (uninitialized) pointer to one. Use "&" when passing it
3479 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3481 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3484 * coffread.c (symbol_file_command): Put semicolon after
3486 Put safe_to_init_tdesc_context in #if defined (TDESC).
3487 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3488 coffread.c: #include <sys/stat.h>.
3489 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3490 Add missing ')' in check for "lc%" and friends. Remove
3492 Declare read_one_sym() at top of file.
3493 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3494 MC68WRMAGIC can have the same value without causing a duplicate
3497 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3499 * Allow a Makefile to be built without building the
3500 tm and xm file links that screw up builds in subdirectories.
3501 This is done with `config.gdb none', then you can do things
3502 like `make gdb.tar.Z'.
3503 * tconfig/none: Config file for no target system
3504 * xconfig/none: Config file for no host system
3505 * config.gdb: If no TM or XM files are called out by the
3506 host or target file, don't make links for them.
3508 * cplus-dem.c: Add documentation.
3510 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3511 simple error, so the user's gdb doesn't crash due to some object
3512 file problem (e.g. somebody is rebuilding the file out from under
3515 * printcmd.c (print_address_symbolic): demangle the symbol.
3517 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3518 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3519 (alldeps.mak): sort and uniq all results from this; duplicates
3520 hose gdb.tar.Z link building. Remove RCS files from
3521 tconfig and xconfig. Add config files for sun386. Add
3522 a few odd files to OTHERS and HFILES.
3524 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3526 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3527 Roll version number to 3.91.5. Make lint work in bindir.
3529 * README: Document cross-debugging and new file structure.
3531 * blockframe.c: Lint. Include "value.h" to declare read_register.
3532 (find_pc_partial_function): remove duplicate line.
3534 * command.h: Lint. Declare error_no_arg and dont_repeat.
3536 * tm-news.h: Remove inadvertently duplicated stuff.
3538 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3539 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3541 * config.gdb: Allow `config.gdb host target' form. Clean
3542 up previous change that printed bogus messages when you just said
3545 * core.c: #include "command.h" for lint.
3548 * main.c: Remove some casts of enums. Lint.
3555 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3557 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3558 read it from memory. This will allow us to save ptrace calls
3559 eventually. Changed caller single_step too.
3561 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3562 that we aren't going to use, saving many ptrace calls, especially
3563 when watchpointing or single stepping. Use some #define's for
3565 (store_inferior_registers): Ditto.
3566 (core_file_command): Use some #define's for constants.
3568 * tm-sparc.h: Add #define's for some register numbers, so we
3569 can eliminate the use of random constants in sparc-xdep.c.
3571 * stack.c (frame_command, print_frame_info, up_command,
3572 down_command) Remove frame_changed, since it
3573 causes a bug and doesn't seem to do anything useful. In some
3574 places it was used as a flag, in others as a stack level (?).
3576 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3577 default is to use the portable (vprintf) version rather than the
3579 * xm-news.h (MISSING_VPRINTF): Add.
3581 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3583 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3585 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3586 about linking debugged programs -Bstatic in the sun?os4 config
3587 files in tconfig and xconfig subdirectories.
3589 * main.c (main): Remove unreached exit(0) now that we exit
3592 * Create TODO file for online bug list. There are too many
3593 "little" bugs to keep track of on paper.
3595 * Change Projects file to refer to bug-gdb@cygnus.com
3596 rather than kingdon@ai.
3598 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3600 * Makefile.dist (VERSION): 3.91.4 now.
3602 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3603 (condense_misc_bunches): Add sanity check that misc_count is
3604 the same as the number of symbols in the bunch.
3606 * coffread.c: rename init_misc_bunches. Pass an argument
3607 to condense_misc_bunches (a zero).
3609 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3610 every time we are called; don't rely on our caller to do it.
3611 (add_file): Remove call to init_misc_bunches.
3613 * mipsread.c: Only warn, don't error, if unknown symbol types.
3614 This keeps an old gdb from falling on its face if it sees newly
3615 extended symbol info. Rename init_misc_bunches.
3617 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3619 * Merge in changes from Per Bothner for DECstations and other
3620 MIPS stuff. The rest is Bothner speaking:
3622 The next message is a merger of Alessando Forin's mips port with
3623 mine. I've tried to use my good if biased judgment to get
3624 the best of both. It *does* need testing.
3626 Some of the changes are general, *not* mips-specific.
3629 Didn't believe in little-endian bit order.
3630 There are still inconsistencies about whether flags
3631 like BITS_BIG_ENDIAN are integer (#if ...) or
3632 boolean (#ifdef ...). I tried to paper over them.
3634 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3635 Moved some misc_function code that was common to
3636 {dbx,coff,mips}read.c to symtab.c.
3637 In the process, I think I cleaned things up a bit.
3638 At the same time, moved obsavestring and obconcat to symtab.c.
3641 Removed obsolete condense_addl_misc_bunches (use
3642 condense_misc_bunches(1) instead).
3645 Needed to include <sys/dir>, at least on DECstations.
3647 valops.c, mips-tdep.c, tm-mips.h:
3648 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3649 conventions (when STACK_ALIGN is insufficient).
3650 Needed on mips, where doubles need 8-byte alignment,
3651 but ints only need 4.
3654 Removed cruft that was not being used.
3655 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3658 Print $ before register-names (I think that makes things a little
3660 Never print two instructions, even if one delays.
3661 Removed hex-disassemble set_cmd. (This is not mips-specific,
3662 so I think the argument is whether it is generally worthwhile or not.
3663 I'm inclined to think not, given how easy it is to
3664 convert between radixes in gdb.)
3667 This is basically Alessando's code.
3668 It doesn't use obstacks; I changed it to use obstacks
3669 in a few minor places where using malloc causes a
3670 memory leak. (Probably, more places could/should be changed.)
3671 I added record_misc_function where it was missing.
3672 In symbol_file_command and add_file_command, I tried
3673 to make the code consistent with more recent versions.
3674 Minor sylistic changes in parse_procedure.
3675 Make a .gdbinfo. psuedo-symbol point back to the real
3676 procedure symbol (using the isym field).
3679 This is basically from my port, but with a lot of details
3680 and a number of routines merged in from Alessando's version.
3681 I basically used my code "raw" backtrace (use heuristics
3682 from the actual code, rather than symbol table info) - though
3683 the idea is Alessandro's. I feel my code is a little cleaner
3684 here, particularly in being a little more flexible, such as being
3685 able to handle gcc-produced code (which it now can).
3686 It also doesn't do frame caching (which is not useful
3687 more recent gdb versions).
3688 I also used my code for push_/pop_dummy, more or less.
3689 I tried to incorporate AF's code for testing sigtramp
3690 while backtracing; I probably got it wrong.
3691 Added mips_print_register, which tries to scrunch as much
3692 information as possible on a screen...
3693 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3694 under mips-pinsn.c), I don't see anything mips-specific here,
3695 and I don't see it being all that useful anyway.
3698 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3699 Use more register names (rather than hard-cases numbers).
3701 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3703 * Hack up 3.90.11 changes:
3705 * Makefile.dist (depend): parameterize $(GCC).
3706 Add solib.c and solib.o.
3707 (readline): Fix vpath for both absolute or relative SRCDIR.
3709 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3710 Also, let the part I didn't understand at least compile so
3711 I can test the rest. FIXME.
3713 * dbxread.c: Fix thinko using strcmp.
3714 (init_psymbol_list): declare static.
3715 (partial_symbol_file_open): Comment cleanups better, avoid
3716 cleaning up the string table since the caller will do that.
3717 Move the stat for mod time into symbol_file_command, temporarily.
3718 (There should be a mod time for each symbol file, eventually,
3719 to control its rereading. FIXME.)
3721 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3722 SunOS, which gives error for shared libs otherwise. (From
3723 Schaefer, probably FIXME needs work for portability.)
3725 * solib.c: Move #include "param.h" to work.
3726 Lowercase all the Uppercase Letters In the Messages.
3727 (find_solib): Clean up inferior_so_name for debug printouts.
3728 Allow no argument, to mean all shared libraries.
3730 * symmisc.c: include param.h to get CLEAR_SOLIB.
3732 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3734 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
3735 to 3.90.11. ChangeLog entries below are from this.
3737 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3741 * Makefile.dist (HFILES): Add tm-sunos.h.
3743 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3747 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
3749 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
3751 * sparc-opcode.h Added single-operand version of rett.
3753 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3755 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
3756 Put parens around gcc_p in expansion.
3758 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3760 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
3762 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3764 * Changes for Sun shared libraries:
3765 blockframe.c (find_pc_partial_function): If a non-text symbol
3766 is found, set *address = pc - FUNCTION_START_OFFSET.
3767 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
3768 Disable breakpoints instead of giving an error.
3769 source.c (select_source_symtab): Initialize cs_pst.
3770 symmisc.c: Call CLEAR_SOLIB if defined.
3771 symtab.h: Make text{low,high} CORE_ADDR not int.
3772 (psymtab): New field addr.
3774 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
3775 (record_misc_function): Give correct type for N_DATA symbols.
3776 (condense_misc_bunches): do "misc_function_count = j" regardless
3778 Take code which is shared between symbol_file_command and
3779 add_file_command and put it into partial_symbol_file_{open,read}.
3780 Split add_file_command into add_file_command and add_file.
3781 Make psymtab_to_symtab read in the string table if the file
3783 Two new parameters to read_dbx_symtab and start_psymtab.
3784 tm-sunos.h: New file.
3786 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3788 * infcmd.c: Change cont_command to continue_command and "cont"
3791 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3793 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
3795 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
3797 * values.c (USE_STRUCT_CONVENTION): Check for structures of
3798 size 1,2,4,8 rather than size < 8.
3800 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
3801 as necessary, not just once.
3803 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3805 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3807 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3809 * tm-news.h: Add CALL_DUMMY_*.
3811 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
3813 * config.gdb: In list_host, list_target, use ${i}, not $i.
3815 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3817 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
3819 * sparc-opcode.h: Change all store floating-point state register
3820 instructions to have the right match & lose fields.
3822 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3824 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
3826 config.gdb: If srcdir != ., create readline directory and
3827 copy a makefile into it.
3829 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
3830 consistency with POSIX.
3832 * breakpoint.c (bpstat_stop_status): Disable watchpoint
3833 when we exit its exp_valid_block.
3835 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
3837 * Makefile.dist: Bump version to 3.91.3.
3839 * Clean up handling of breakpoint commands (somewhat).
3840 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3842 inferior.h: Add breakpoint_proceeded to inferior status struct
3843 and globals; save it and restore it.
3844 (clear_breakpoint_commands): Cleanup, remove old #define.
3846 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3847 (save_inferior_status, restore_inferior_status): handle it also.
3848 (proceed): Remove earlier code that set breakpoint_proceeded.
3849 It is now set only in clear_proceed_status.
3850 (clear_proceed_status): Cleanup, use bpstat_clear rather
3851 than clear_breakpoint_commands. No callers need the stop_bpstat
3852 between clear_proceed_status and proceed.
3854 infcmd.c: Add breakpoint_proceeded definition and comment.
3855 (cont_command, jump_command, signal_command): Move call to
3856 clear_proceed_status right next to call to proceed.
3858 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3859 caller's argument while running down the chain of breakpoints.
3860 Use new variable "breakpoint_proceeded" to determine when
3861 a command that it executes moves the inferior past the
3863 (bpstat_clear): Handle NULL argument.
3864 (bpstat_clear_actions): Avoid useless call to
3865 breakpoint_auto_delete.
3866 (delete_breakpoint): Clean up bpstat's that are pointing to
3867 the deleted breakpoint from the stop_bpstat chain.
3868 (breakpoint_auto_delete): Simplify.
3870 * Clean up handling of EOF, error on stdin, etc. This was
3871 prompted by a network problem that caused gdb to go into an
3872 infinite loop filling up its malloc'd memory.
3874 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
3875 not clear_breakpoints_commands, which is now gone.
3876 (main): If command_loop returns (e.g. from EOF on stdin), do
3877 a quit_command (looping back to command_loop if quit_command
3878 doesn't really quit).
3879 (command_loop): check result from command_line_input and
3880 exit if it returns NULL, rather than passing the NULL to
3882 (gdb_readline): Free malloc'd result space before returning
3885 * utils.c (query): Handle C-d to mean "yes", just as if the
3886 input was not a terminal. Also avoid infinite loop if EOF
3887 occurs in mid-input-line before newline. This allows
3888 query to be used at EOF on stdin with reasonable results.
3890 * infrun.c (proceed): Set breakpoint_proceeded.
3892 * values.c (value_as_long): Avoid infinite recursion for enums.
3893 (_initialize_values): Fix typo in help msg (kingdon).
3895 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
3896 RL_LIB for linking. This allows -lreadline for linking
3897 and nothing for dependencies, once readline is a real library.
3899 * config.gdb: Jim Kingdon: give useful error message if the
3900 host or target type is not recognized.
3902 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
3903 it just defines it. Dumb, but deal with it.
3905 * Jim Kingdon suggests:
3906 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
3908 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
3910 * Makefile.dist (VERSION): Bump version # to 3.91.2.
3912 * Clean up Bothner's changes.
3914 * blockframe.c (clear_pc_function_cache): New function.
3915 * blockframe.c: remake cache_pc_function_* static.
3916 * dbxread.c (symbol_file_command): remove references to
3917 cache_pc_function_* variables.
3918 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
3919 * printcmd.c: Avoid kludging a global variable (addressprint)
3920 to avoid printing the address of a string twice. Instead,
3921 pass the format letter 's' down low enough that it can be seen
3922 to avoid this problem.
3923 (print_formatted): Pass format arg to value_print.
3924 (restore_addressprint): Remove function.
3925 (do_examine): Avoid hacking addressprint, cleanups and such.
3926 (print_frame_args): Add a comment to a Bothner change.
3927 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
3928 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
3929 to wipe out the values cached in blockframe.c.
3930 * symtab.c (find_method): Add comment saying how big you must
3931 allocate to be "big enough". Per being terse again.
3932 * valprint.c (val_print): Handle format letter "s" to print
3933 strings without addresses. Add comment to vtbl printing code
3934 which casts with wild abandon. Rearrange reference-printing
3936 @0xaddr: value (print w/addressprint)
3937 value (print w/~addressprint)
3938 @0xaddr (parameter lists w/addressprint)
3939 or nothing (parameter lists w/o addressprint)
3941 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
3943 * Merge more changes from Per Bothner:
3945 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
3946 annoying) that I tried to improve it. Here are my suggestions.
3948 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
3951 Do automatic de-reference when taking the address of a reference.
3953 Don't deref_ref when printing parameter lists.
3955 More attempts at treating refernences properly.
3957 In val_print, if deref_ref==0, don't print dangling " = ".
3959 Add COERCE_REF macro, which de-references an REF.
3961 * Merge changes from Per Bothner:
3963 * Fixed (Sony news)-specific configuration problems.
3964 * Fixed other problems with using vanilla pcc and libc (enum problems;
3965 assumption that vsprintf exists).
3966 * Some major speed-ups (finc_pc_partial_function now caches a match;
3967 parsing avoids duplicate symbol_lookup calls).
3968 * Changed handling of baseclasses (no longer use baseclasses field
3969 of struct type, use the first n_baseclasses fields instead).
3970 * Various minor changes/fixes, most C++-related.
3973 Cache the most previous match from find_pc_partial_function.
3974 (Save both low and high ends of matching function's pc range.)
3975 This speeds up the loop of infrun.c:wait_for_inferior quite
3976 a bit, and makes step/next commands much zippier.
3978 Added an enum->int cast (otherwise, some compilers barf).
3980 No longer set baseclass offset to 0, since multiple
3981 inheritance now mostly works.
3982 Added a number of casts, to shut up compiler warnings
3983 (after stabs where made enums, not ints).
3984 When discarding a symbol table (in symbol_file_command),
3985 must clear the cache introduced in blockframe.c.
3986 Don't convert $vtbl_ptr_type to vtbl any more.
3987 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
3988 Mask off sign bit emitted by g++ for virtual table offset.
3989 Set voffset to -1 (not 1) for static member functions.
3991 Changed parsing/lexing of names to avoid doing symbol lookup twice
3992 (once when lexing to determine symbol class, once for real).
3993 Now only call symbol_lookup once. Fields of 'this' win especially big.
3995 Subpress printing addr twice in the case of 'x/s addr'.
3997 lookup_basetype_type is no longer used.
3998 Add find_methods as recursive helper function to decode_line_1.
3999 This allows multiple inheritance to work.
4000 Also, once one or more matches has been found, do not look in
4001 base-classes. (Baseclass methods would be overridden, anyway.)
4003 Removed baseclasses array in struct type.
4004 Instead of using baseclasses[i], use fields[i-1].
4005 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
4006 Changed sign convention of voffset (previous was inconsistent).
4008 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4010 Used to assume existence of vsprintf. Re-written to not need it
4011 if HAVE_VPRINTF is undefined.
4013 typecmp was too pessimistic. Made it less so.
4015 Don't print space after address.
4016 If vtable points to a misc symbol (with 0 offset), print it,
4017 since that indicates the actual class of the object.
4018 Changed ype_print_derivation_info to use new inheritance
4019 scheme (without baseclasses vector).
4021 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4022 Also, changes needed because TYPE_BASECLASSES were removed.
4024 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4026 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4029 If there is no path set, and the symbols don't indicate what directory
4030 a file was compiled in, look in the current directory. But either
4031 a path or a known compilation directory will prevent this.
4034 Three independent bug fixes:
4035 * Remove the #if 0 block that breaks some stuff.
4036 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4037 adapt gdb to either SunOS 4.0.* or 4.1.
4038 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4041 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4044 (type_print) Demangle the name being printed.
4045 (type_print_base) Handle botched demangling without coredump (tiemann).
4048 (check_stub_method): Document routine.
4049 (tiemann) fix bug for no-arg functions
4050 Avoid clobbering beyond end of malloc'd storage.
4051 Terminate the argument list properly.
4053 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4055 * Changes merged by John Gilmore:
4058 In breakpoint_1, use new print_address_symbolic instead
4059 of find_pc_partial_function. (This forces use of assembler-level
4060 addresses, and avoids misleading non-mangled source-level names.)
4062 Generalize ansi argument such that -1 means skip arglist totally.
4063 Removed global variable print_ansi_qualifiers (which made
4064 code non-reentrant), in favor of extra explicit arguments
4065 to internal routines.
4067 Add new helper function print_address_symbolic.
4068 Use find_pc_misc_function instead of find_pc_partial_function
4069 (since we want assembler-level symbols here).
4071 Print unknown function as just "f (...)", not "f (...) (...)".
4072 Use new fputs_demangled explicitly.
4074 Fixed a typing violation (problem: value.h cannot be imported
4075 without renaming many variable in this file).
4076 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4077 decode_line_1: Moved forward some never-reached code.
4078 Made decode_line_2 skip function prologues correctly.
4080 fputs_filtered should not demangle by default.
4081 Add new fputs_demangled to demangle on demand..
4083 Change value_struct_elt to use value_primitive_field (using recursive
4084 utility function search_struct_field). This allows foo.bar to work
4085 for multiple inheritance (so far only for data fields).
4086 Change check_field in the same way (recursive helper function
4087 to support multiple inheritance).
4088 (Note: there are more of these problems that I haven't fixed.
4089 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4090 value_of_this: 'this' symbol name is now just "this", note "$this".
4092 Don't print static members.
4093 Avoid printing "members of <type>" if there are none.
4094 Simplified type_print_derivation_info by merging duplicate code.
4095 Remove useless blank lines in type_print_base (ptype command).
4097 Added declaration of new routine value_primitive_field.
4099 Added value_primitive_field which is generalized version of
4100 value_field that can handle multiple inheritance (non-zero offsets etc).
4101 Re-implemented value_field to call value_primitive_field.
4103 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
4105 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4106 delete the whole environment. Karl Berry reported the bug.
4107 * source.c - fix openp to avoid //'s in filenames, which
4108 trigger an Emacs bug causing it to not be able to find files
4109 when running gdb in a window.
4110 * dbxread.c - zap the #if 0 that botches the add-file code.
4111 It seems to work a lot better without all the code commented out.
4113 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
4115 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
4118 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
4120 * Makefile - added a ${CFLAGS} to a couple of entries,
4121 added remote-sa.sparc.c
4122 * added remote.sa-sparc.c, a modification of remote.c
4123 which conducts a dialog directly with the SparcStation prom.
4124 * breakpoint.c, infrun.c, sparcdep.c added
4125 remote_insert_breakpoint(), and remote_remove_breakpoint()
4126 to breakpoint.c instead of directly writing breakpoint instructions.
4127 * sparcdep.c on remote_debugging,there is no need
4128 to remove signle step breakpoint instructions.
4129 * main.c added "-epoch" flag and "int epoch_interface" to main.c
4131 * printcmd.c - epoch interface sends lisp expressions to open up
4132 epoch windows on inspection.
4133 * valprint.c - added arrayprint, and addressprint and made adding
4134 format controls easier
4135 * wait.h added a couple of undef's because we were getting
4136 complaints about WSTOPSIG and WTERMSIG begin redefined.

4164 should print ANSI qualifiers (such as `const' and `volatile').
4165 All callers changed to call with ANSI == 1, except from
4166 `check_method_stub', which uses old-style syntax.

4206 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
4207 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
4208 when printing the type.
4210 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)

4232 step_resume_break_address != NULL, even if another_trap.
4233 If trap_expected and we enter sigtramp, then set up a
4235 If trap_expected is set when we hit the step_resume_break,
