1 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3 * Makefile.in: Bump VERSION to 3.98.1
4 * infrun.c (child_create_process): Use execlp to find the
5 shell to exec our target program. This requires some fiddling
6 with `environ' since there is no execlpe().
8 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
10 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
11 Minor rearrangement of refcard permits two new make targets--
12 gdbrc.dvi DVI output for refcard, using CM fonts
13 gdbrc.ps PostScript refcard, using PS fonts
15 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
19 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
20 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
22 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
24 * doc/gdb.texinfo: last changes for release.
25 Minor typo and formatting fixes; incorporated most fixes remaining from
26 filed mail commenting on earlier drafts.
28 Added warnings: pipes don't work in run command;
29 conditions are converse of assertions;
30 step over fn without debug info goes to next fn;
31 vars may have "wrong" values near fn entrance, exit
33 Added example from Kingston on printing repeated nonadjacent values
35 Added explicit mention that in Emacs gdb mode C-c and C-z are like
36 shell mode for signals
38 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
39 doesn't sound so much like its parent "Stopping and Continuing"; also
40 moved entries on continue to top of section, so they don't get lost.
42 Improved installation directions in appendix, added manual formatting
45 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
47 * configure.in: Remove xm.h and tm.h even if we aren't linking
48 new ones, so "./configure sun4; ./configure none" does the right
49 thing. Assume that alldeps.mak and depend are already built in
50 srcdir, and avoid running "make" (particularly "make depend",
51 which involves "gcc") from inside configure. Build Makefile
52 directly rather than building Makefile.conf first.
53 * configure: Regenerate with above changes.
54 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
55 to 3.98. Revise gdb.tar.Z procedure to produce a file
56 called gdb-$(VERSION).tar.Z but which unpacks into a
57 directory called "gdb". Move non-source files out of
58 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
59 (depend): Don't try to do "gcc expread.y".
60 (expread.o): Update dependencies by hand.
62 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
65 Fixed a variety of small typos that prevented info from formatting
66 cleanly; altered too-long heading for GPL Appendix, as discussed
67 w/RMS; Changed date on cover to July 91.
69 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
72 (1) Applied some fixes due to comments from Larry Breed (easier ones
74 (2) Eliminated use of @footnote---had my doubts about it anyways, and
75 it's broken in latest texinfo
76 (3) Introduced *some* use of [] for optional arguments, where
77 explanation is not simpler by listing cmd w arg and cmd w/out arg
78 separately. Still not using @deffn.
79 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
80 couple of headings are too long. Need patches to texinfo or revision
83 * Partial update to README (which still needs work for this
84 release!): (1) use of configure corrected for new script,
85 (2) "make gdb.dvi" and "make gdb.info" mentioned.
87 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
89 * symtab.c (lookup_symbol): Don't complain right off about
90 no debug symbols; use the misc function vector first.
91 (list_symbols): Use misc function vector to find symbols
92 that don't have debug info, and print them.
93 (find_pc_symtab): Temporarily avoid fatal() when psymtab
94 PC range doesn't match symtab PC range, as it does on the
95 MIPS because our symtab reading isn't perfect.
97 * dbxread.c (dbx_symfile_read): Make warning about
98 "no debug symbols" slightly nicer.
100 * source.c (select_source_symtab): If "main" symbol exists,
101 but decode_line_spec can't find line info, don't just return
102 a zero; try other source symtabs or give an error.
104 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
105 their low addresses first, then rip through fixing high addrs.
107 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
109 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
111 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
113 * Minor, mostly mechanical, cleanup of doc subdir for clean
114 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
115 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
117 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
119 Mostly MIPS and general symbol-reading fixups.
121 * doc/gdbint.texinfo: Add documentation on symbol-reading
124 * mipsread.c: Remove kludges around #include "ecoff.h".
125 Remove redefinitions of a_magic, etc, no longer used.
126 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
127 Fix global overview comments to match symfile.c protocol.
128 (mipscoff_new_init): Eliminate cur_hdr if we have one.
129 (mipscoff_symfile_read): Eliminate unused code. Avoid
130 sorting all the symtabs, when all we have read here is psymtabs.
131 The symtabs are sorted as they are created anyway. Tell
132 condense_misc_bunches whether we're mainline.
133 (psymtab_to_symtab_1): Pass filename when recursing, to make
134 stack trace more informative.
135 (parse_partial_symbols): Assume cur_hdr as argument.
136 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
137 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
138 the TYPE_NAME of char *, since that's done in symfile.c.
139 (free_numargs, parse_symbol, add_symbol, add_block,
140 shrink_linetable): Declare these fns void.
141 (upgrade_type): Convert tree of if's to switch. Clean up
142 bogus "off == 0" handling with a complaint. Avoid setting
143 field bitpos and bitsize of array with lower and upper bounds.
144 Check specified bitsize of elements against their actual type's
145 bitsize, and complain if different. Complain about unknown
147 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
148 (psymtab_to_symtab_1): Print names of subsidiary files that
149 are being read in. FIXME, we read far too many files. This code
150 is not the problem, the problem is in parse_fdr where the psymtabs
152 (cross_ref): Result should indicate that we used one aux entry
153 normally, or two if we encountered a "next" entry. This used
154 to leave the caller pointing at the wrong aux entry.
155 (add_symbol): If overflowed cur_block, reallocate it larger,
156 chase all pointers to it, and complain(), rather than clobber memory.
157 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
158 (new_field): Only allocate one field initially, not two.
159 Pull ++ out of macro argument. Simplify.
160 (_initialize_mipsread): Avoid initialization of importd
161 global_psymbols and static_psymbols.
163 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
164 to properly set pst->symtab; avoid searching for it.
165 (symfile_fns): Improve comments, add a FIXME.
166 * dbxread.c: Update comments to reflect symfile protocol.
167 (read_ofile_symtab, end_symtab): Return the symtab.
168 (psymtab_to_symtab_1): Set pst->symtab.
170 * coffread.c (coff_symfile_read): tell condense_misc_bunches
171 whether we're mainline.
173 * symfile.h (sym_fns): Remove unused sym_discard member.
174 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
176 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
177 the environment variable is not.
178 * infcmd.c (finish_command): Use filtered printfs.
179 * cplus-dem.c: Add struct tags to a few unnamed structs.
180 * valops.c (value_coerce_array): Improve comments.
181 * valprint.c (type_print_varspec_suffix): Print array size only
182 if greater than zero.
183 * m88k-tdep.c: Shift some lines left by one space, that had
184 apparently been trashed at some point.
185 * TODO: More things to do, a few got done.
187 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
189 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
190 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
192 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
193 * expread.y, findvar.c, symmisc.c: Ditto.
194 * printcmd.c (address_info): Update printed forms of LOC_
195 symbols. Elim LOC_EXTERNAL.
196 (print_frame_args): Keep track of param stack offsets before
197 re-looking up to find the local register param is kept in.
199 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
200 Further integration of mipsread into gdb. Eliminate unused
201 routines, duplicate declarations. Handle static symbols in
202 psymtabs as well as external symbols. When reading symtabs,
203 insert symbols into the correct block (global, static, or a local
205 (read_mips_symtab, parse_partial_symbols): Don't pass useless
207 (mipscoff_symfile_read): Don't call select_source_symtab.
208 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
209 rather than SYMBOL_VALUE.
210 (parse_external): Comment clobbering of top_stack.
211 (parse_partial_symbols): Update comments. Allocate and parse
212 static symbols as well as external symbols. FIXME, enum values
213 are not handled in this pass, but should be. Inline new_psymbol.
214 Use SYMBOL_VALUE_ADDRESS.
215 (psymtab_to_symtab_1): Read symbols into global static block
216 by default (until enter some function's local block context).
217 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
218 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
220 * source.c (select_source_symtab): Select a source symtab
221 from either the symtabs or, failing that, the psymtabs.
222 (list_command): Update error message.
223 (forward_search_command, reverse_search_command): Use getc, not
224 fgetc, for speed. FIXME, add comment about buffers that die if
225 overrun by long line.
227 * values.c (unpack_field_as_long, modify_field): Avoid shifting
228 by an entire word, which is not portable, if we have a 32-bit
229 field. (Code in dbxread.c already turns such bitfields, if
230 aligned, into ordinary ints, but fixing this will help for other
231 symbol formats and for future changes.)
232 * core.c (core_open): Handle ANSI const brain death.
233 * utils.c (vprintf): Fix varargs typo.
235 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
237 * findvar.c (find_var_value): Handle &function better.
238 * TODO: Document work needed on &fn and &array.
239 * printcmd.c (print_address_symbolic): New arg is the prefix
240 to print if a name is printed.
241 (print_address_demangle): Honor "set print address" now.
242 Use new arg above to improve spacing of output.
243 * valprint.c (val_print): When printing function pointers,
244 print symbolic form too.
245 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
247 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
249 * core.c (memory_error): Reword error msg to mislead less.
251 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
253 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
254 parse_partial_symbols): Use newer BFD internals (external_filehdr
255 and external_aouthdr), byte-swap the fields that we care about
256 before using them, and make the file header data local to
257 read_the_mips_symtab rather than global.
259 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
261 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
262 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
264 * main.c (command_line_input): Flush stdout and stderr
265 before every call to readline. This reportedly fixes a bug
266 that comes up in Sys V running emacs-gdb and/or xxgdb,
267 when stdin/out are pipes or sockets.
269 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
271 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
272 Avoid declaring Makefile dependencies, because GNU Make stupidly
273 tries to update it if we do.
275 * coffread.c: Revise for minor changes to bfd internal coff
278 * configure: If -template= is given a relative path, make it
279 absolute before recurring in subdirectories.
281 * configure, configure.in, Makefile.in: Install "configure" script
282 as replacement for config.gdb.
283 * config.gdb, Makefile.dist, Makefile.sdir: Remove
284 * README: Update for configure, mostly. FIXME.
286 * Add dec3100 as equivalent to littlemips. Indicate in all host &
287 target config files that they are for the host. When the lines
288 get copied into the Makefile, this makes it more obvious what's
291 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
293 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
294 tabs, which end up in the disassembler output inadvertently.
296 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
298 Make it compile cleanly in an ANSI GCC2 environment.
300 * blockframe.c: <stdio.h>
301 * cplus-dem.c: free takes a void *, ifdef __STDC__
302 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
304 * defs.h (alloca): Avoid doing anything if alloca already def'd.
305 * stddef.h, stdlib.h: Remove these files.
306 * symtab.c: Avoid declaring qsort, close.
307 * symfile.c: Avoid declaring close.
308 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
309 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
311 Assorted other changes.
312 * dbxread.c: include "libaout.h", not "liba.out.h".
313 * printcmd.c (print_frame_args): Set recurse properly for
314 indentation of struct and array parameters.
315 * valops.c (value_cast): Allow cast to void.
316 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
317 single_step() in a target-independent fashion.
318 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
319 set up to be ready to continue. This makes us target independent.
320 * infptrace.c (child_resume): Remove call to single_step; now
321 can single step a SPARC target of any kind.
323 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
325 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
326 docn into separate sections---basically chapters, plus two loose
327 pieces that can be configured to go in different places. This
328 allows GNU m4 to preprocess the manual without coredumping.
330 * Makefile.dist: tell TeX where to find texinfo.
332 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
334 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
335 the new target "rdl-apps.texinfo" which captures the Makefile
336 variable that records where to find the Readline libraries.
338 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
340 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
341 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
342 * defs.h (const, volatile): Only define if not already defined.
343 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
345 * README: Update for release 3.95.
346 * config.gdb: Don't create readline dir in subdir builds.
347 * main.c: Include with "..." form for non-system include files,
348 so "gcc -MM" for "make depend" works.
349 Include readline files with "...h" rather than <readline/...h>.
350 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
352 * coffread.c: Undo minor damage done by Rich Pixley. Use
353 different internal and external representations of COFF
354 data structures. Use new BFD routines for swapping them in and
356 * symfile.c (free_named_symtabs): Avoid freeing file names that
357 are null or empty. Old i960 tools seem to produce files that
358 claim to have empty names, causing each successive file read
359 to blow away the previous one.
360 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
361 Move deferred_stores to top of file, but don't separate its
362 #define's from its variable. Add commentary.
363 * Makefile.dist: Fix Rich damage; undo "configure" changes in
364 favor of keeping the (working) config.gdb. Move readline
367 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
369 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
371 * infptrace.c (fetch_registers): no result, since now void.
372 * tconfig/news: target depends on m68k-tdep too.
374 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
376 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
379 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
380 applied various small fixes due to or inspired by RMS comments
382 * doc/gdb.texinfo: finished using all RMS comments, save those for
383 appendices on readline and cmd history (which are in other source
386 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
388 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
389 chapter 9; (2) documented 'break' command's menu mode for
390 overloaded names, in response to hgs problem report C++ p-31
392 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
394 * doc/gdb.texinfo: (1) better introductory example; (2) more
395 consistent use of @code, @samp, @file, @kbd throughout; small
396 cleanups to first three nodes; (3) new "Contributors" node;
397 (4) Appendix, Renamed Commands; (5) divert specialized startup
398 instructions to "Targets" chapter for generic manuals, while
399 leaving them up front for manuals specific to specialized
400 environments; (6) apply fixes from RMS comments through chapter 4.
402 * pretex.m4: modify explanatory text slightly (and redefine
403 "regexp") to keep GNU m4 from complaining. (It still crashes
404 later, but one step at a time...)
406 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
408 * readline/readline.c (update_line): Avoid dereferencing a pointer
409 before comparing it to its bounds. Saber caught this.
410 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
411 and only set PC if tgetstr returned non-null. Saber caught this.
413 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
415 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
416 stuff for config manual) here where it counts; updated
417 to use new subdir structure (gdb/doc/).
419 * Makefile: generated from above via
423 * gdbint.texinfo: added instructions on generating gdb.info* files
424 locally for release. These are ordinary info
425 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
426 Makefile)---but due to use of texinfo 2, can't count on makeinfo
427 to generate these, so we distribute them already formatted.
429 * gdb.texinfo: included full Info node and menu crud (as generated
430 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
432 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
433 put in comments-for-future gdb.info target (one day makeinfo will
436 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
438 * gdb.texinfo: Updated to include new or old undocumented
439 commands, at least the following (perhaps some others I forgot to
440 record): info f, info float, info path, info program, info s, info
441 set, info source, info terminal, info types, info user, set/show
443 Also covered all recent GDB command renames for v4.
445 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
447 * mipsread.c: Rather than keeping count of how many symtabs
448 and psymtabs we have, for sorting purposes, count them when
449 we need to sort. This fixes bug in rereading of symbol tables.
451 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
453 * infcmd.c: renamed "info path" to "show paths"
454 * gdbrc.tex: documented above.
456 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
458 * remote.c: Fix comments.
459 * utils.c (error): Force out any pending wrap output.
461 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
463 * Makefile.dist: Roll VERSION to 3.95.
464 Fix up "saber_gdb" to work again.
465 * saber.suppress: Update.
467 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
468 symtab.h, target.c, target.h: Lint.
469 * core.c: setup and select frame after reading shared libs,
470 else reading shared libs will clobber them. Lint.
471 * utils.c (error): Force out any buffered wrap text.
473 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
475 * remote.c: Remove decls of memory_insert_breakpoint
476 and memory_remove_breakpoint, no longer used. (Suggestion of
479 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
480 to make it easier to interface to "configure"'d libraries.
482 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
484 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
485 aliases for set/show print.
487 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
489 * coffread.c (coff_sym_fns) [TDESC]: Make the type be m88kbcs.
491 * m88k-tdep.c (IEEE_isNAN): New function.
493 * infrun.c, m88k-tdep.c, m88k-xdep.c: Change
494 initialize_{tdesc,dcontext} to init_{tdesc,dcontext}.
496 * infrun.c [TDESC]: Add a bunch of crud.
498 * xm-88k.h [__GNUC__]: Don't define memset.
500 * m88k-xdep.c: #if 0 out push_breakpoint.
502 * tm-88k.h: Define GET_SAVED_REGISTER.

997 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
998 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
999 Call target_preopen from open routine.
1001 * main.c: Rename editing_info to show_commands.
1002 (_initialize_main): Rename "info editing" to "show commands".
1004 * source.c: Rename directories_info to show_directories.
1005 (_initialize_values): Rename "info directories" to "show directories".
1007 * values.c: Rename convenience_info to show_convenience.
1008 (_initialize_values): Rename "info convenience" to "show convenience".
1010 * copying.awk (_initialize_copying): Rename "info copying" to
1011 "show copying" and "info warranty" to "show warranty".
1012 Rename {copying,warranty}_info to show_{copying,warranty}.
1014 * symfile.c: Rename add_syms_command to add_symbol_file_command.
1015 (_initialize_symfile, add_syms_addr_command):
1016 Rename add-syms to add-symbol-file.
1018 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
1020 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
1021 * symfile.c (clear_symtab_users_once, cashier_psymtab,
1022 free_named_symtabs): Move these routines from symmisc.c.
1023 * symmisc.c (same): same.
1024 (free_symtab): Make non-static.
1025 * symtab.h (free_symtab): Declare as exported void fn now.
1026 * dbxread.c (end_symtab, end_psymtab): Change comments.
1027 (initialize_dbxread): Call dbx_new_init() in case the first
1028 command is add-symbols.
1029 * target.c (dummy_target): Permit add_syms_addr_command.
1031 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1033 Permit symbols to be superseded when new symbol files have
1034 been read in, particularly for VxWorks.
1036 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
1037 to the main file, as well as to include files. Also, put global
1038 functions into the global psymtab, to make "i fun" work.
1039 (end_psymtab): Free named symtabs and psymtabs for a file, once a
1040 new psymtab for it has been read.
1041 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
1042 a file, once a new symtab has been read for it.
1043 * mipsread.c: FIXME. We need to do the same for MIPS, but it
1044 looks harder to determine the top-level block before it's been
1045 queued to the psymtab list.
1047 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
1048 If we have wiped out any old symbol tables, clean up at end of
1050 (symbol_file_command): Don't reference symfile_fns if it's zero.
1052 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
1053 defines for the blocks of a blockvector that contain global and
1054 file-static symbols and the first of the smaller scope contours.
1055 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
1056 decode_line_1, make_symbol_completion_list): Use the above.
1057 * coffread.c (end_symtab, patch_opaque_types): Ditto.
1058 * dbxread.c (end_symtab): Ditto.
1059 * expread.y (block): Ditto.
1060 * mipsread.c (throughout): Ditto.
1061 * symmisc.c (free_named_symtabs): Ditto.
1063 * symtab.c (list_symbols): Process the first symbol of the
1064 static psymbols list.
1065 (types_info): Restore this function from its untimely #if 0.
1066 It's not perfect, but it is better than nothing.
1067 (_initialize_symtab): Restore "info types".
1069 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1071 * m68k-stub.c: Remote stub for 680x0's, created from
1072 rem-m68k.shar (which is removed).
1073 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
1074 Remove RCS log stuff now that we use CVS and it blows our diffs.
1076 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1078 * symmisc.c (free_named_symtab): Make it work, in its current
1079 kludgy fashion. Change result to indicate if we blew away bkpts.
1080 * dbxread.c (end_symtab): Accumulate result from
1081 free_named_symtab and print warning if we blew user's state.
1082 * symfile.h: free_named_symtab now returns an int.
1084 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1086 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
1087 is the first symbol read, even if not mainline.
1088 (dbx_psymtab_to_symtab): symfile might be zero, cope.
1089 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1090 (set_section_command): New command ("section xxx yyy" -- should
1091 be renamed to "set section xxx yyy" FIXME) which sets the
1092 base address of a section of the exec file, overriding the
1093 virtual address that BFD reports.
1095 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1097 * exec.c: Add add_syms_addr_command to exec_ops, so you can
1098 load symbols at any address while examining an exec file.
1100 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1102 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1103 for printing the float info is host-dependent, not
1104 target-dependent. FIXME.
1105 * i386-pinsn.c: Move #includes to top, remove useless ones.
1106 * i386-tdep.c: Don't bother including <.../reg.h> since we
1107 don't use it (and it doesn't exist on host systems).
1109 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1110 Convert negative numbers properly.
1111 (ieee_test): Make numbers really random; fix format arg.
1113 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1114 * core.c (core_detach): Unpush core_ops, which might not be on
1115 top. We used to just pop the top, which broke things. Don't
1116 need dont_repeat() any more.
1117 (core_file_command): Psst! Don't repeat it.
1118 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1119 * expprint.c (print_subexp): Avoid switch fallthru on
1120 BINOP_ASSIGN_MODIFY, so we can print += and such.
1121 * frame.h: Fix typo.
1122 * inflow.c (kill_command): After killing inferior, print our
1123 current frame in the core file, if we have one.
1124 (generic_mourn_inferior): When inferior dies, either select
1125 the current frame (in the new target, e.g. core file), or
1126 set both the current and selected frames to NULL.
1128 Changes from Peter Schauer.
1130 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1132 * Make all file names fit in 14 characters (sigh and damn!):
1133 mv hp300hpux-xdep.c hp300ux-xdep.c
1134 mv symmetry-xdep.c symm-xdep.c
1135 mv symmetry-tdep.c symm-tdep.c
1136 mv convex-opcode.h convx-opcode.h
1137 mv tm-vxworks960.h tm-vx960.h
1138 mv tm-vxworks68.h tm-vx68.h
1139 mv Makefile.srcdir Makefile.sdir
1140 mv gdb-int.texinfo gdbint.texinfo
1141 mv remote-sa.m68k.shar rem-m68k.shar
1142 mv remote-multi.shar rem-multi.shar
1143 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1144 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1145 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1148 * command.c (user_info_1, user_info): New command for listing
1149 the user-defined commands.
1151 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1153 * dbxread.c (really_free_pendings): Clear file_symbols
1154 and global_symbols after freeing them; otherwise, running
1155 this function twice (if it appears twice on the cleanup
1156 chain), we try to free things twice.
1158 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1159 based on text_addr (the address of text in core), not on addr (the
1160 offset between text in the .o file and in core). This change
1161 is from Peter Schauer.
1163 * main.c: Define ALL_CLEANUPS as a cast of zero.
1164 (return_to_top_level): Use it.
1165 (main): Do all cleanups after each command run as part
1166 of the gdb startup sequence. Also do all cleanups before
1167 entering the command loop, and every time we exit the command
1168 loop and reenter. Before, the cleanups from the startup sequence
1169 were being left undone until the first error!
1170 (command_loop): Rename do_nothing cleanup to command_loop_marker
1171 so we can see it easily when examining the cleanup chain.
1172 (init_signals): Add another do_nothing for signal handling.
1173 (quit_command): Only try to kill target if it has execution.
1174 Problems in the target stack got us into a state where
1175 inferior_pid was nonzero but none of the targets had execution.
1176 In this state you couldn't exit gdb.
1178 * dbxread.c: Two changes from Peter Schauer.
1179 (echo_command): Fflush output after an echo command.
1180 (show_history): Pass all args to cmd_show_list.
1182 * utils.c (init_malloc): Call mtrace to turn on tracing
1183 if the environment variable MALLOC_TRACE is set to a file name.
1184 * mtrace.c: Add source file which provides a log of every malloc,
1185 free, and realloc to a trace file.
1186 * mtrace.awk: Add source file which analyzes the trace file.
1187 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1188 (VERSION): Roll to 3.94.3.
1190 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1191 (check_duplicates): Don't bother with watchpoints.
1192 (set_raw_breakpoint): Comment about danger of this routine.
1193 (watch_command): Parse and eval all args before calling
1196 * solib.c (find_solib): Avoid error in referencing memory to
1197 see if any more shared libraries have been added. This is
1198 particularly useful if the target has terminated. Bug reported
1201 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1202 in bringing up 3.94.2 on the Sun-3.
1204 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1205 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1206 expression (in scope) before reenabling watchpoint.
1207 * signame.c (init_sigs): Add missing declaration of i, fix
1208 sys_siglist declaration.
1209 * source.c (list_command): Fixed range computation to use
1211 * stack.c (backtrace_command): Do not allow command if target has
1212 no stack, print informative error message.
1213 * target.c (target_command): Do not write into command line
1214 because this fails if the target command is used in a user defined
1215 command. [This change was enhanced by gnu to support any-
1216 unique-prefix matching on target names.]
1217 * valops.c (value_struct_elt): Avoid infinite loop on an
1218 erroneous attempt to print the member of function (try p main.p).
1220 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1222 * expread.y (name_no_typename): Avoid reduce/reduce errors
1223 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1224 Since the GDB parser really doesn't use name_no_typename in a
1225 name-only context, the parser can't tell the diff between
1226 names and numbers here. Avoid allowing a name_no_typename
1227 to be a NAME_OR_*INT to resolve the conflict.
1229 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1231 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1233 * valprint.c (val_print_fields): bitfield printing didn't handle
1234 byte order. Indirect through a few more fns to cope.
1236 * values.c (modify_field): also cope with byte order.
1238 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1240 Cleanup for release 3.94.2:
1242 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1243 include files. Roll version to 3.94.2.
1245 * coffread.c (init_stringtab): Read length into unsigned char
1246 array before swapping; don't assume 32-bit longs.
1248 * target.c (target_info): Don't bother with get_sym_file, just use
1249 the symfile global variable.
1250 * symtab.h, symfile.c (get_sym_file): Delete it.
1252 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1253 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1254 (read_type): Replace one more error() with complain().
1256 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1258 * i960-tdep.c: Fix copyright attribution.
1260 * config.gdb: Quote all backquotes in doublequotes. You can
1261 quote me on that. BSD 4.4 shell found this one.
1263 * infptrace.c (throughout): The third argument to ptrace is an
1266 * infrun.c (wait_for_inferior): When program has terminated, we
1267 have to call target_terminal_ours before we pop that target off
1268 the stack (e.g. before a call to target_kill or
1269 target_mourn_inferior). This fixes problem where a program
1270 terminates, then GDB stops for (tty output) and you have to type
1271 "fg" to the shell to resume it. FIXME: This code for what to
1272 do after termination really should be in normal_stop instead.
1274 * gdbcore.h (read_memory_check): Change declaration; it changed
1277 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1278 4.4 prereleases, this avoids a bug in their sgtty compatability
1280 * remote.c: Use terminal.h rather than hand-rolling the same.
1282 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1283 * utils.c (strsave, strstr): Fix arg types.
1284 * valprint.c (val_print): lint
1286 MIPS symbol table support from Per Bothner:
1288 * symfile.c (symtab_fns): Remove initializer table that needs to
1289 be hacked for each new symbol file format supported.
1290 (add_symtab_fns): New function, chains symbol table
1291 handlers into the global list.
1292 (symfile_init): Search this list.
1293 * symfile.h: Add next pointer, declare add_symtab_fns.
1294 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1295 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1297 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1298 symbol *). Thus, we no longer need the hack to trash
1299 pst->filename. Good, since that hack confused code in symfile.c!
1301 (reorder_symtabs, destroy_all_symtabs): Removed static
1302 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1303 Instead, the latter now uses a temporary array (stack-allocated
1304 from an obstack, and then freed).
1306 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1307 haven't been set in the outermost stBlock of a procedure. This was
1308 a problem with f77 binaries on Ultrix 4.?.
1310 (new_symtab, new_symbol, new_type): Continue changing code to use
1311 obstacks more and otherwise conform to dbxread internal style.
1312 Made the free_code of symtabs be free_linetable (as in dbxread)
1313 instead of free_contents. This implies memory leaks when reading
1314 a new symbol table, until the conversion is finished. Did change
1315 (struct symbol) and (struct type) to be allocated on the
1316 symbol_obstack. Blocks and blockvectors are among the things
1319 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1320 tested much, but it solved one problem (reported by Meissner), and
1321 cleans up some other things. The problem happened when an
1322 included file contains actual code (functions) and not just
1323 definitions. The mips coff is a little inconvenient there, since
1324 it may cause a procedure to be mapped to the wrong psymtab.
1326 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1327 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1328 this will need work for the new core paradigm.
1330 Opcode patches from the net:
1332 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1333 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1334 missing altogether - they are added here. From Bruce Bauman.
1335 * mips-opcode.h: The low mask for C0 instructions was too small.
1336 From Garrett Lau. I modified the fix to check the entire 32-bit
1339 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1342 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1344 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1346 * dbxread.c (read_type): Pointer subtraction (value_sub in
1347 valarith.c) sometimes failed because the types of the
1348 pointers being subtracted were not identical.
1349 These differed because dbxread.c was allocating pointer types
1350 using dbx_alloc_type+smash_to_pointer_type instead of
1351 lookup_pointer_type. I failed to find a justification for the
1352 former, so I changed it to use the latter. Similarly, I
1353 replaced smash_to_function_type by lookup_function_type,
1354 and smash_to_reference_type by lookup_reference_type.
1356 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1357 _initialize_mipsread): corresponding changes.
1359 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1361 * source.c (mod_path): Do tilde_expand on each component of the path,
1362 rather than on the (list of) paths as a whole.
1363 (print_source_lines): Set first_line_listed in addition to
1364 current_source_symtab and current_source_line. If the source was
1365 not findable, after a "dir" command to fix the problem,
1366 a "list" would get the wrong lines.
1368 While I was there... (gnu):
1370 * dbxread.c (read_type): Change error to complaint.
1372 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1374 First attempt at detailed understanding of symbol table memory alloc.
1376 * dbxread.c (dbx_symfile_read): Free our string table if we
1377 aren't the mainline. Free the "info" struct since we're done with
1379 (init_psymbol_list): Free any previously allocated psymbol lists.
1380 (): FIXME: Should realloc-down the psymbol lists when done reading
1381 the main symbol file?
1383 * symmisc.c (free_symtab): Free fullname field too.
1385 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1386 (REGISTER_ADDR): Make result type unsigned int.
1388 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1389 define REGEX must also define REGEX1 (its dependency).
1391 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1393 * tconfig/i960: No longer works, points you at vxworks960 or
1396 * xgdb.c, XGDB-README: Remove file. Users can get the much
1398 * Makefile.dist: Remove all trace of xgdb.
1400 * breakpoint.c (breakpoint_1): Pass demangle arg to
1401 print_address_symbolic.
1402 (clear_breakpoints): Remove unused function.
1403 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1404 (breakpoint_re_set): Use catch_errors to do them all anyway.
1406 * gdb-int.texinfo (Host versus Target): Add section on what is
1407 a "host" feature versus what is a "target" feature.
1409 * infcmd.c (path_command, path_info): Handle the PATH variable
1410 (object search path) as conveniently as the source search path.
1411 * environ.c (set_in_environ): Set some vars in GDB's environment,
1412 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1413 * source.c (mod_path): New function, from guts of
1414 directory_command, modifies a path. Used by path_command.
1415 (directory_command): Call it.
1416 * defs.h (strsave): Declare.
1418 * utils.c (sevenbit_strings): Add new printing option.
1419 (printchar): Use it.
1420 (strsave): Provide this handy helper routine.
1421 (set_width_command): Rename set_screen_width_command.
1422 (_initialize_utils): "set screen-width" => "set width";
1423 "set screen-height" => "set height"; add sevenbit-strings.
1425 * infcmd.c (do_registers_info): Print floating point registers
1426 in raw hex as well as float format, regardless of whether it is
1427 a "virtual" convertible register.
1428 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1429 regs as a double, just in case it's being used that way.
1430 * values.c (unpack_long): Comment on array/function coercion.
1431 (unpack_double): Argument is in target byte order now. For
1432 integer arguments, just call unpack_long and float the result.
1433 * m68k-tdep.c: include defs.h for "const" handling.
1434 * remote-nindy.c: Use ieee-float stuff.
1435 (nindy_fetch_registers): Unpack double regs to host double, then
1437 (nindy_store_registers): Pack extendeds to host double, flip
1438 around by misusing unpack_double, send as target double.
1440 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1441 zero, as when stopped at the first instruction of a process.
1443 * blockframe.c: Fix filename in comment (param.h => tm.h).
1444 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1445 * tm-68k.h: Fix typos.
1447 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1449 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1451 * coredep.c (fetch_core_registers): Pass end-address of register
1452 section to register_addr as expected. Don't call supply_register
1453 if we'd just pass it garbage.
1455 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1457 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1459 * target.c (push_target, target_info): Cast enums to int for < or
1462 * stack.c (print_frame_info): Identify source file & line
1463 even if we can't print it.
1465 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1467 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1469 Clean up IEEE floating point support.

1473 doubles and various target IEEE extendeds.
1474 * m68k-xdep.c: Eliminate assembler code for extended floats.
1475 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1476 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1477 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1478 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1479 double_to_ieee_extended.
1480 * i960-tdep.c: Define ext_format_i960.
1481 * m68k-tdep.c: Define ext_format_68881.
1482 * sparc-tdep.c: Define ext_format_sparc, though unused.
1483 * Makefile.dist (HFILES): Add ieee-float.h.
1484 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1487 Obsolete the "coffstrip" program in favor of using BFD's strip.
1489 * nindy-share/coffstrip.c: Remove file.
1490 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1491 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1492 * tconfig/nindy960: Remove reference to coffstrip.o.
1494 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1496 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1498 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1499 * dbxread.c: Remove static symfile_bfd.
1500 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1502 * inftarg.c (child_detach): Pop the child_ops vector if the
1503 detach is successful.
1504 * remote-nindy.c (nindy_create_inferior): Don't push a new
1505 nindy_ops since nindy uses the same one for execution and memory
1507 * core.c (core_ops): Use child_attach and child_create_inferior
1508 rather than default attach and create_inferior functions.
1510 Handle floating point registers in core files.
1512 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1513 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1514 This version untested since BFD doesn't yet support sun3 core
1516 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1517 conventions. Fix comments and style. This version has not
1518 been compiled yet, since we have no HP inhouse.
1519 * core.c (get_core_registers): Look for two sections, ".reg"
1520 and ".reg2", and pass both to fetch_core_registers sequentially.
1522 Revise directory path yet again.
1524 * source.c (forget_cached_source_info): Not static any more.
1525 (init_source_path): New default source path is "$cdir:$cwd".
1526 (dir_command): Handle variable arguments ($cdir, $cwd).
1527 (source_info): Print "Compilation directory" rather than
1528 "Originally compiled in" to remind people of $cdir.
1529 (openp): If the path contains $cwd, use current directory.
1530 (open_source_file): If compilation directory is known, replace
1531 first $cdir in path with the compilation directory.
1532 (print_source_lines): Even if we can't print the lines, set the
1533 current symtab and line for future commands like "info source" or
1534 "breakpoint". Also, error message now contains the file name,
1535 line number, and file access error message.
1536 (_initialize_source): Fix help text to describe changes.
1537 * main.c (cd_command): Forget cached source info when we chdir.
1538 * utils.c (strstr): Add simple implementation.
1540 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1542 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1543 Byte-swap COFF symbol tables if necessary when reading them in.
1544 Use complain() to replace error message in one spot. Needs
1545 corresponding change in bfd/coff-code.h to make some symbol
1546 swapping routines non-static.
1548 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1550 Merge changes from Eirik Fuller, for UTek.

1557 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
1558 declarations of errno.
1560 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1562 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1563 <rpc/rpc.h> and <rpc/types.h>.
1565 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1567 * i960-tdep.c (examine_prologue): Add new argument limit,
1568 which stops the scan at the end of the prologue, or at the PC.
1569 This fixes a problem where it walks down into the code for the
1570 user's statements if that code looks like function prologues.
1571 Mark Fox and I have been bouncing this code back and forth, making
1572 small changes to it. Callers changed to match.
1574 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1576 Cleanup for gdb-3.94 release final:
1578 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1579 the .c files from vx-share and nindy-share, from the various
1580 macros, since they are not found via ALLDEPFILES.
1581 (SFILES): Add tm-i960.h.
1582 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1583 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1585 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1586 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

1590 * am29k-tdep.c: Add contribution line.
1591 (examine_prologue): Cache information about function prologues in
1592 the misc-function-vector to avoid lots of references over the
1593 serial line while examining instructions.
1595 * core.c (core_close): New function made from cleanup_core.
1597 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1598 remote-vx.c, remote.c, target.c, target.h,
1599 Update target_ops vector to add attach, close, and load entries.
1600 Use add_syms_addr_command, not add_file_addr_command, for
1601 add_file. Break out close routine from existing code.
1603 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1604 they are in an obstack.
1605 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1607 (define_symbol): Add symbol type parameter; change callers;
1608 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1609 it to influence the symbol class on the i960.
1610 (define_symbol): Swap LOC_CONST's into target byte order.
1612 * exec.c (exec_close): New function.
1613 (exec_file_command): Call it.
1615 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1616 Fix byte order of frame pointer.
1617 (read_var_value): Result of 0 if var's value can't be found,
1618 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1619 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1620 (locate_var_value): Use read_var_value and use its lazy address
1621 as the location of the var's value. Lint.
1623 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1626 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1627 obsolete Intel versions in favor of vxgdb versions.
1628 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1629 code dealing with byte order of values, which Intel did in host byte
1630 order rather than gdb-4's target byte order.
1631 (i960_frame_chain_valid): Move to nindy-tdep.c.
1632 (examine_prologue, skip_prologue, frame_find_saved_regs,
1633 frame_args_address, leafproc_return, saved_pc_after_call,
1634 pop_frame): Add vxgdb versions from Mark Fox.
1635 (examine_prologue, frame_struct_result_address): Add code
1636 to deal with the saved value of G13 (struct return address
1638 (frame_args_address): Modify Mark's version to prefer the
1639 saved value over the current value in the topmost frame.
1640 Cache result in the frame info to avoid performance hair in
1642 (print_fault): Add gdb960 code for printing faults.
1643 (_initialize_i960): Actually call check_host.
1645 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1646 add stub routines. FIXME, these currently just return zero!
1648 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1649 (attach_command): Call target_attach, not target_open, now.
1651 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1652 (child_attach): Rename from child_open.
1653 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1654 don't confuse it with a zero step_resume_break_address.
1656 * inftarg.c (child_detach): Eliminate inferior_pid test.
1657 (child_files_info): Clean up message a bit.
1658 (child_ops): Use child_attach, not child_open, to attach.
1660 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1661 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1662 findvar.c to here, since it depends on the contents of the
1663 shadow_contents of breakpoints, but keep if #if 0 since it is
1666 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1669 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1670 (ptype_command, display_command): Eliminate have_inferior_p and
1671 have_core_file_p in favor of target_has_stack or
1672 target_has_execution.
1673 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1674 code for actually finding the values of arguments, though we still
1675 keep track of the maximum stack offset for use in printing unnamed
1676 arguments. Handle missing FRAME_ARGS_ADDRESS.
1678 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1679 (struct nindy_regs): Define registers passed to/from nindy.
1680 (nindy_fetch_registers, nindy_store-registers): Translate between
1681 nindy and GDB formats for the registers.
1682 (dcache_init): Statically allocate the cache, since it was being
1683 allocated by a malloc that was never freed anyway.
1684 (nindy_create_inferior): Error, not core dump, if no exec file.
1685 (nindy_before_main_loop): Use target_load, not target_add_file.
1687 * remote-vx.c (net_load): Specify large timeout for load
1688 requests. Allow user to break out with INTERRUPT.
1689 (net_break): Remove useless code, clean up. Change callers.
1690 (parse-args, skip_white_space, find_white_space): Clean up arg
1691 parsing to cope with quoted strings.
1692 (net_wait, net_quit): Never call error, just return status.
1693 (vx_read_register, vx_write_register): Cleanup status checking.
1694 #ifdef the code based on which CPU we are using (960 or 68k),
1695 FIXME, this should be completely general but it isn't yet.
1696 (vx_xfer_memory, vx_resume): Cleanup status checking.
1697 (vx_run_files_info): Improve message.
1698 (vx_load_command): Renamed from vx_add_file_command. Allow load
1700 (net_ptrace): Remove unused routine.
1701 (vx_wait): Adopt code from vxgdb960 to cope with broken
1702 connections to target machine and prompt to disconnect. Remove
1703 debug printouts. Map some EVENT_'s to SIGnals.
1704 (add_symbol_stub, vx_open): Print names of object files we found,
1705 and "ok" if we read their symbols OK. Clarify output in general.
1706 (vx_attach, vx_detach, vx_kill): Add these commands.
1707 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1708 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1709 "info files" output, and create_inferior, since we already have
1712 * stack.c (frame_info): Replace Frame_unknown with 0.
1713 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1714 (return_command): Pop until the PC matches as well as the FP,
1715 so it works even if the FP is shared with another function,
1716 as in "frameless" or "leaf" procedures.
1718 * symfile.c (load_command): renamed from add_file_target_command.
1719 (add_syms_addr_command): renamed from add_file_addr_command.
1720 (add_syms_command): Stub to call target_add_syms.
1721 (_initialize_symfile): Change command names and descriptions,
1722 add-file => add-syms, and load from alias to its own command.
1724 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1725 maybe_kill_then_create_inferior): Default for attempts to start
1726 a process, if one is already running, is to ask about killing
1727 it and retry if yes.
1728 (upstack_create_inferior): #if-0 it, strata obsolete it.
1729 (push_target, unpush_target, pop_target): to_close() a target
1730 before unstacking it.
1731 (target_info): Renamed from target_files_info.
1732 (_initialize_targets): Rename "i files" as "i target", accessible
1735 * target.h: Improve comments about the target_ vectored routines.
1737 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
1738 Convert commenting style to standard GNU style.
1739 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
1740 (SKIP_PROLOGUE): No longer a no-op.
1741 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1742 (*_REGNUM): Sort register numbers.
1743 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1744 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1745 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1746 are now 10 byte extendeds, not 8 byte doubles.
1747 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1748 for nindy versus vxworks targets. FIXME, this should possibly go
1749 in the target vector.
1750 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1751 frame_saved_regs and arg pointer with each frame.
1752 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1753 (FRAME_ARGS_ADDRESS): Use cached result.
1754 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1755 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1756 (PRINT_RAMDON_SIGNAL): Call print_fault.
1757 (POP_FRAME): Now works.
1759 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1760 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1761 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1762 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1765 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1766 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1768 * valarith.c (value_subscripted_rvalue): Avoid handling
1769 floats and doubles specially; it gave alignment errors. Lint.
1771 * valops.c (value_of_variable, value_of_this): Error if unknown
1774 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1775 to avoid alignment problems.
1776 (value_print): Handle unknown value address.
1777 (cplus_val_print): Two args are ignored; remove them. Change caller.
1778 (val_print): Use unpack_long rather than pointer-deref.
1781 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1782 to avoid alignment problems.
1783 (value_being_returned): Error if return value unknown.
1784 (set_return_value): Add bogosity warning, FIXME. *
1786 * TODO: A woman's work is never done.
1788 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1789 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1790 Add ieee-float.o to OBS.
1791 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1792 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1793 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1795 Changes to generalize the VxWorks RPC protocol slightly, to handle
1796 i960 as well as 68000.
1798 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1799 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1800 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1801 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1802 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1803 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1804 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1805 so they will move in target byte order rather than network
1806 byte order (happens to be the same).
1808 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1810 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1812 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1815 Add contribution lines to various files, showing where they
1818 * breakpoint.c (break_insn, check_break_insn_size,
1819 read_memory_nobpt): Remove to mem-break.c.
1821 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1824 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1825 entry has bad register number. This change is not
1826 tested in this release, FIXME.
1828 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1831 * value.h: Force value's contents field to be aligned to hold
1832 at least a double or a long long (if supported). This avoids
1833 doing bcopy's in and out of the contents field.
1835 (step_1): Avoid coredump under obscure circumstances when we
1838 * symtab.h (misc_info): Add field to misc function vector for
1839 any kind of cached information the target code desires. AMD
1840 29000 uses this to avoid repeating examine_function_prologue's.
1842 * coffread.c: Lint. Remove static symfile, read_section_header.
1843 core.c (have_core_file_p): Lint: remove.
1844 expprint.c (print_subexp): Lint.
1845 infptrace.c, valops.c, valprint.c: lint.
1847 Roll in changes from vxgdb-5.0.1:
1849 * symtab.h: Comment byte order of each address class. Add
1850 LOC_LOCAL_ARG for frame-relative args (960).
1851 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1852 symtab.c, symmisc.c: ditto.
1854 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1856 * remote.c (remote_resume): Error if resume with a signal.
1858 * symfile.c (prim_record_misc_function): Clear misc_info.
1859 (fill_in_vptr_fieldno): Check stub type of arg.
1861 * valops.c (value_cast): Avoid looking up names of types whose
1862 name we don't know, to prevent coredump. Sun CC produces typedef
1863 rtx and the name of *rtx is zero...
1865 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1867 Roll in changes from final AMD 29000 port (Tiemann).
1869 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
1870 for ../include/a.out.encap.h. This might not work now that BFD
1871 is separately compiled. Instead, BFD support for encap will have
1872 to translate machine type 29k into the right COFF_MAGIC.
1874 * infcmd.c: Remove references to inferior_pid that aren't used
1875 in actual ptrace calls; use target_has_execution, etc.
1876 (have_inferior_p): Remove function.
1877 (program_info): Print target info rather than "process number";
1878 avoid gratuitous messages unless from_tty.
1879 (run_stack_dummy, finish_command): Set proceed_to_finish.
1880 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
1881 main.c: Lint. Lose have_inferior_p().
1882 inferior.h (have_inferior_p): Remove, lint.
1883 (proceed_to_finish): Add flag to ask that all regs be saved
1884 by normal_stop, for the few commands that need it, speeding up
1885 serial I/O. Add comments to stop_registers.
1887 * remote-eb.c: Remove newline from breakpoint message we grep
1888 for. Never time out when running the user program.
1892 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1894 Roll in changes from vxgdb-5.0.1:
1896 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
1897 symbol in its raw form, we are processing an unlinked ".o" file.
1898 See if the target environment has assigned it an address, using
1899 target_lookup_symbol (VxWorks does), and enter it into the symtab
1902 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
1903 68k versions for a simpler version that assumes zero FP at bottom.
1904 Fixes bug of truncated stack reports.
1906 * target.h (target_lookup_symbol): Define this routine's args
1907 and result, finally.
1909 * target.c (nosymbol): Default routine for target_lookup_symbol.
1910 (target_default): Default lookup_symbol and call_function too.
1911 (files_info): Only print has_all_memory warning if a non-dummy
1914 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
1915 vx_convert_from_virtual): If target does not have floating point,
1916 zero register "values", and avoid doing cross-net conversions.
1917 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
1918 (vx_open): Rearrange code that attaches to target and reads
1919 symbols for all loaded modules, to work if some of the modules
1920 are not accessible. Add symbol_stub() and add_symbol_stub()
1921 as callbacks from catch_errors(). Allow connect attempt to be
1922 interrupted painlessly with ^C (FIXME, there are still some bugs
1923 if the interrupt happens during symbol reading.). Print
1924 final message with puts_filtered, since symbol messages are
1929 * main.c (catch_errors): Only print errstring if non-null.
1930 (command_loop): Avoid an ioctl per command to test ISATTY.
1932 * remote-vx.c (net_load): make static; avoid sophomoric msg.
1933 (vx_xfer_memory): Return correct result!
1934 (vx_files_info): Indicate whether target has float or not.
1935 (vx_lookup_symbol): Complain, not error, if target gone.
1936 (vx_open): Print "Connected" msg before disabling immediate-quit.
1937 [FIXME: lookup_symbol and vx_open changes need testing.]
1939 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
1940 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
1941 contributor lines and update copyrights to 1991.
1943 Changes from an attempted H-PUX host port:
1945 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
1946 defines PT_ATTACH and PT_DETACH but not PT_KILL.
1947 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
1948 * remote-vx.c: include <sys/time.h> for HPUX.
1949 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
1950 "core_file_command" routine to BFD regime. May not work yet.
1952 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
1954 * xgdb.c: Replace X10 version with some VJ version.
1955 (FIXME: Its copyright assignment is not on record.)
1956 * xgdb.c: Update include files to X11R4 (Xaw crud).
1957 (xgdb_display_source, create_text_widget): fix call to
1958 get_filename_and_charpos. Rewack source window stuff for X11R4
1959 (gleaned from include files, and "nm's" of binary libraries, since
1960 I had no doc available).
1961 (append_selection, append_selection_word): Disable with FIXME
1962 since R4 changed interface here.
1963 (create_buttons): Add back the old set of buttons.
1964 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
1966 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
1967 Roll VERSION to 3.94 (not yet final though).
1969 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1971 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
1972 obstack_int_grow, obstack_int_grow_fast): Eliminate
1973 cast on left of assignment, which gives MIPS cc fits and is
1976 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
1977 F_ALIAS. Use printf, not fprintf, when not passing a file
1979 (compare_opcodes): Check that identical instructions have
1980 identical opcodes, complain otherwise.
1982 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
1983 was reported by Roland McGrath.
1984 (unimp): Only match if exactly zero instruction. (Roland)
1985 (branches and traps): Generate all variations of these
1986 instructions with macros, based on a single call that defines
1987 each condition name and its binary representation.
1988 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
1990 * valprint.c (val_print_fields): Take, and use, format parameter.
1991 This means that "p/x struct" again prints the elements in the
1992 desired format. Changed callers.
1994 * stack.c (frame_info): Use filtered output, and indicate wrap
1995 points. Remove kludgy formatting designed to avoid line wrap.
1997 * utils.c (wrap_here): If the line is already full (because
1998 we had printed a long indent or long wrapped string), do an
1999 immediate newline-and-indent.
2001 * m68k-pinsn.c (print_insn_arg): Bugfix from
2002 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
2003 instruction is incorrectly disassembled as bkpt #8.
2005 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
2006 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
2007 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
2008 and then will dump core (sometimes). I traced it back to an
2009 uninitialized symfile_name in psymtab_to_symtab.
2010 (const_vol_complaint): Add quotes to message.
2011 (define_symbol): Only believe line number if gcc_compiled.
2012 Avoid allocating symbol if we will not return it.
2014 Add target strata support so that newly established targets go
2015 into their right place in the target stack (e.g. a new exec file
2016 doesn't wipe out the ability to access the running process).
2018 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2019 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2020 and initialize it properly in all the targets.
2022 * target.h: Document strata. Change return type of push_target.
2024 * target.c (nomemory): new function for dummy memory access.
2025 (tcomplain): Rename complain, now also used in symfile.c.
2026 (push_target): Push targets within strata. New return value shows
2027 whether new target is on top of stack or not. Always keep dummy
2029 (target_files_info): Ignore dummy target.
2031 * core.c (core_open): Warn user, and skip accessing file, if the
2032 core target is not the topmost target in the stack.
2033 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2036 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2037 target_ops, it doesn't belong there since we have no regs there.
2038 Change name of target from machine => memory to clarify.
2040 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2042 * Freeze version 3.93 for release.
2044 * Makefile.dist: Handle vx-share and nindy-share subdirs
2045 properly when building gdb.tar.Z.
2047 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2048 printed in various places, so I could change just one copy.
2050 * dbxread.c, coffread.c: Change references to bfd->iostream
2051 to cast to FILE *, now that BFD avoids needing types defined
2052 in other header files.
2054 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2056 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2057 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2058 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2059 (actually gcc -Wall).
2061 * dbxread.c: Remove first_global_sym, last_global_sym, since
2062 they are never referenced.
2064 * defs.h (baud_rate): Declare.
2065 main.c: Define it, and add the -b option to set it.
2067 * gdb-int.texinfo: Add text on how to define a new host or target
2068 architecture, prompted by Per Bothner's questions about MIPS
2071 * gdb.texinfo: Document "complaints". Change doc of -q since
2072 gdb no longer prints the copyright and blurb if you specify a file
2073 name to be debugged (just like Emacs). Add doc for Nindy-specific
2074 command line flags for specifying target serial port and such.
2075 Update copyright to 1991.
2077 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2078 has taken over for us the job of ripping up executable files. The
2079 crud caused Per Bothner's port to not compile.
2081 * infrun.c (normal_stop): Avoid printing "Program exited
2082 normally" if we are in batch mode. This allows a GDB which
2083 executes a program on a target system, to behave like a Unix
2084 command (input from stdin, output to stdout, no extraneous
2087 * main.c (main): Allow additional machine-dependent command line
2088 options to be specified with the ADDITIONAL_OPTIONS,
2089 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2090 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2091 processing to occur just before the main loop with
2092 BEFORE_MAIN_LOOP_HOOK.
2093 (main): If a "core file" argument is specified, and it is not a
2094 core file, try it as a process ID to attach.
2095 (symbol_completion_function): Attempt to cope with
2096 "show screen-" TAB, not very successfully. This needs more work,
2098 (batch_file): New function, returns whether we are reading
2099 commands from an interactive tty on stdin, or from somewhere else.
2100 Called by normal_stop since it doesn't get from_tty passed down
2101 to it like many commands do.
2103 * remote-nindy.c: Handle command line options for nindy
2105 (nindy_before_main_loop): Prompt user for tty name if they
2106 don't specify it before getting to the interactive command loop.
2108 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2109 and -r command line options. Also add hook before main loop
2110 to make it easy to specify a tty.
2112 * TODO: More things to do, one done.
2114 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2116 * dbxread.c: Make complaint() calls pass pointer, not struct.
2117 Add complaints about badly formatted C++ type information
2118 (const/volatile indicator, and parse errors resulting in
2119 error_type). Fix C++ virtual member fn comment.
2120 (read_struct_type): Avoid bumping pointer if we got a parse
2121 error; this prevents our walking beyond the end of a string.
2122 Terminate loop on null char as well as semicolon.
2123 (process_one_symbol): Fix the LBRAC fix so that it uses the
2124 last previous SLINE, FUN, or SO record's PC address. C++ debug
2125 symbols did not have SLINE records in a useful order compared
2126 to the LBRAC records.
2127 (define_symbol): Handle "catch" records.
2129 * symtab.c (check_stub_type): Added new complain
2130 `stub_noname_complain' and added a consistency check to
2131 keep the debugger from crashing when finishing from an
2132 exception frame. A real fix will be needed later.
2134 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2136 * infcmd.c (attach_command): Make global.
2138 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2139 but make them easy to comment out. Perhaps later they should
2140 be enabled by what CPU you configure for? FIXME.
2141 (VERSION): Roll to 3.93.
2142 (pinsn.o): Remove rule for obsolete file.
2143 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2145 Run down a problem that manifested by printing the wrong function
2146 name in stack traces of read_ofile_symtab. Turned out that the
2147 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2148 the LBRAC symbol with an address in the *data* segment, which
2149 blew our binary search through the blocks.
2151 * dbxread.c: Use the complain() facility consistently to bitch
2152 about problems in the symbol file we are reading.
2153 (finish_block): Add code to check the nesting of the blocks;
2154 complain and Procrust them to fit if wrong.
2155 (make_blockvector): Check the order of the blocks, complain
2156 [but don't cope] if wrong.
2157 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2158 symbols to be sure their PC value is greater than the last SLINE
2159 (line number) symbol we've seen, complaining and adopting the
2160 SLINE PC value if wrong.
2162 * symfile.h (struct complaint, complaint_root, complain,
2163 clear_complaints): Add.
2164 * symfile.c (complain, complaint_root, clear_complaints): Add
2165 facility to deal with non-fatal complaints and to regularize their
2167 (symbol_file_add): Clear complaint counters to allow new complaints.
2168 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2170 * dbxread.c (dbx_symfile_read): Remember the address and size
2171 of the string table for the main symbol file, so we won't read it
2173 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2174 to avoid reading the string table yet again. Lint.
2175 (throughout): Improve filtered output, including word wrap.
2176 (read_range_type): Improve Bothner's fix to handle other types too.
2178 * utils.c: Improve line wrap implementation. Handle unlimited
2179 width by making chars_per_line unsigned.
2180 (puts_filtered): New, easy, function.
2182 * defs.h (puts_filtered): add.
2184 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2185 call the identical sort_symtab_syms() in symfile.c instead.
2187 * expread.y: Suggest the `file' command rather than `symbol-file'.
2189 * command.h (enum var_types): Add zinteger for seroable
2191 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2192 nested if's into a switch.
2194 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2195 we did not stop because of a breakpoint (it must have been for
2196 some other reason, like a "stepi"), so don't print anything.
2198 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2199 doesn't include <sys/types.h>, old SunOS's require it for
2202 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2204 A test port of gdb-3.92.6 to the Sony NEWS.
2207 Don't normally link in remote- or vx stuff.
2208 Some of it doesn't compile, and it wastes space for 99% of the users.
2209 Remove reference to no-longer-used HAVE_VPRINTF.
2210 Fixed BFD_DEP typo to BFD_DIR.
2212 Fix cast in arg to bfd_h_getlong.
2213 Make char *prefix be const.
2214 Fix how certain range types are mapped into builtin unsigned int types.
2216 Remove 2 #includes. They cause errors (on Sony, at least),
2217 and aren't needed (they wern't in earlier versions).
2219 print_address_symbolic should never demangle labels
2220 (since it prints *assembler-level* labels).
2222 [This was superseded by the change to printcmd below.]
2225 Add some "volatile" return types to avoid warnings.
2226 If MISSING_VPRINTF add vprintf function and not just macro
2227 (since vprintf is used in printcmd.c).
2229 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2230 (The latter isn't grokked by some PCC-based compilers.)
2232 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2234 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2235 * nindy-share/coffstrip.c
2236 Added some forward declarations (otherwise, gcc complains
2237 about implicit extern redefined as static).
2239 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2241 Changes inspired by Per Bothner:
2242 * printcmd.c (print_address_symbolic): Take additional parameter
2243 specifying whether to demangle.
2244 (print_address): Pass in asm_demangle to control demangling.
2245 (print_address_demangle): New fn, takes explicit arg to control
2247 * utils.c: Add new vars demangle and asm_demangle, and let them
2249 (fputs_demangled): If !demangle, just print the argument.
2250 (fprint_symbol): If !demangle, just print raw symbol.
2251 * valprint.c (val_print): Call print_address_demangle rather than
2252 print_address, to cause demangling to depend on the global
2253 rather than assembler-level demangling setting.
2254 * WHATS.NEW, gdb.texinfo: Document.
2256 * main.c (show_command): Show all settings if no arg.
2257 (initialize_main): Make "info set" the same as naked "show".
2258 * command.c (cmd_show_list): Handle prefix commands in the
2259 list, and print the name of the setting as well as its English
2260 description and value.
2262 Allow gdb functions to specify where a line should wrap if it
2263 exceeds the size of a terminal line. Use it to make the output
2265 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2266 of the right size when screen width changes.
2267 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2268 (wrap_here): New fn, indicates a point in the output where we
2269 should wrap the line rather than just letting it overflow at a
2271 (fputs_filtered): Implement wrapping.
2272 (n_spaces): New fn, returns a pointer to N spaces.
2273 (print_spaces_filtered): Use n_spaces.
2274 * defs.h (n_spaces): Declare.
2275 * stack.c (print_frame_info): Wrap with 4-space indent after
2276 fn name and before filename and line number.
2277 * printcmd.c (print_frame_args): Wrap with 4-space indent
2278 before each argument name is printed.
2279 * valprint.c (value_print): Wrap with no indentation before
2281 (val_print_fields): Wrap with indentation relative to nesting
2282 level before each field name.
2283 (val_print): Wrap with nesting indentation before array elements.
2284 * command.c (do_setshow_command): Avoid extra newlines,
2285 wrap with 4-space indent around values printed, end with period.
2286 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2288 * breakpoint.c (breakpoint_1): Implement addressprint for
2289 "info breakpoints" display. Change file name and line number
2290 format to " at file:nnn" rather than " (file line nnn)".
2291 * gdb.texinfo: Document.
2294 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2296 Frozen for gdb-3.92.6 release.
2298 README, WHATS.NEW: Update for 3.92.6 release.
2300 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2301 coffread.o from configs since it is now built by default.
2302 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2303 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2304 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2305 from configs since it is now built by default.
2307 Makefile.dist: Update for release 3.92.6. Handle files that
2308 have been moved to ../include, ../getopt, or ../bfd. Add
2309 saber.suppress and tests directory. Add config.status to
2310 the release (it will say "none").
2312 coredep.c: Minor formatting fixes.
2314 These changes were made in early December but only checked in now:
2315 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2316 nindy-share/nindy.c: lint
2317 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2318 register values coming back from the target; we store values
2319 in target byte order everywhere.
2321 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2323 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2325 * valprint.c (cplus_val_print, val_print_fields): New functions,
2326 which print C++ objects. They conspire to avoid printing a
2327 virtual base class more than once, following all the twists and
2328 turns of C++ virtual base rules.
2329 (val_print): Call the above rather than do it by hand.
2331 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2332 symbol file, not for added files like shared libs. This really
2333 needs to be generalized to a timestamp per file.
2335 * core.c (cleanup_core): Avoid coredump if no core file.
2337 * config.gdb: Accept -host or -target in place of +host or
2340 * coffread.c (find_linenos): Avoid desupported BFD interface
2341 to line numbers. We still read them manually rather than using
2342 BFD's "generic" features.
2344 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2346 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2348 * Makefile.dist: Eliminate use of $< in explicit targets.
2350 * readline/Makefile: Use $< rather than $*.c, which does not
2351 include the VPATH in GNU Make.
2353 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2354 copies of tconfig/i960, added for global configuration
2355 compatability. All i960 versions can read both coff and b.out.
2357 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2358 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2361 * TODO: Think of more things to do.
2363 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2365 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2366 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2367 64-bit float conversion.
2369 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2370 equivalent to sun?os4 so global config works.
2372 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2374 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2376 * main.c: Only declare linesize once; declare pagesize not at
2377 all, since it is never used.
2378 (main): Clear newly allocated line before it is used.
2380 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2382 Further stabilization for the Intel 960.
2384 * Makefile.dist: Parameterize the location of the "include"
2385 and "bfd" directories, as well as "getopt". Add symfile.c.
2386 Link in both dbxread and coffread. Fix up "make depend" to
2387 rewack the locations of include, bfd, and getopt in its output.
2389 * README: Document moving include files, improve some of
2392 * coffread.c: Move common code out to symfile.c. Change
2393 symbol_file_command style interface to use new *_symfile_init
2394 and *_symfile_read interface under BFD. Use BFD internal
2395 info to locate line table, symbols, etc.
2397 * core.c (core_fetch_registers): Rename to get_core_registers
2398 to avoid confusion with fetch_core_registers.
2399 (register_addr): Move to coredep.c, which is already machine
2400 dependent. This leaves core.c pretty clean of dependencies.
2402 * coredep.c (register_addr): Accept this routine from core.c.
2404 * dbxread.c: Move common code (with coffread.c, etc) into new
2405 symfile.c. Each psymtab now contains a pointer to the
2406 format-dependent function that knows how to read it in. Make
2408 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2409 (process_one_symbol): Add code to complain about a "compiler bug
2410 we muzzle here", if we actually see it.
2412 * eval.c (evaluate_subexp): Insert missing "break" statements
2413 in code that determines whether a variable is an lvalue in
2414 memory, register, or whatever. I detected this via a compiler
2415 bug in which it *almost* mashed out the whole switch statement.
2417 * gdb-int.texinfo: Add minor sections on configuring gdb for
2418 release, and about the README file.
2420 * infcmd.c (registers_info): Fix formatting somewhat. Still
2421 not as pretty as before, but it handles byte swapping.
2423 * remote-nindy.c: If data cache routines are interrupted while
2424 waiting for the remote end, be sure that any uninitialized cache
2425 blocks are on the free list, not on the valid list!
2427 * symfile.h: Flesh out this header file with all the various
2428 routines and variables that have been merged in from dbxread.c
2429 coffread.c, and symtab.c to symfile.c.
2431 * symfile.c: New file, containing code common to dbxread.c,
2432 coffread.c, and some code from symtab.c. All generic code for
2433 reading symbol files should be in here now.
2434 (unrecord_misc_function): Remove unused function.
2436 * symtab.h: Remove file-reading things to symfile.h.
2438 * symtab.c: Remove file-reading things to symfile.c.
2440 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2441 to decode i960 fault types.
2443 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2444 target.c: Change type of the "resume" function from int to void,
2445 since its result was never used.
2447 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2449 * main.c: Replace "stupid" with "caution"; you now "set caution
2452 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2454 * infcmd.c (do_registers_info): Call val_print to deal with the
2455 byte order of the registers being printed. FIXME, this makes
2456 the formatting of the output uglier.
2458 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2459 defined, call it for signals the debugger doesn't itself use.
2460 The i960 uses this for more detailed fault information.
2462 * remote.c (remote_open): If arg is null, print help rather than
2465 * sparc-xdep.c (register_valid): Avoid declaring size, since
2466 various modules will think of various sizes depending on the
2467 architecture of their tm-file. FIXME, we need protection against
2468 actually entering one of those modules, which would clobber
2469 storage if not for the target architecture compiled into gdb.
2471 * stack.c (up_command, down_command): Always print the frame
2473 (up_silently_command, down_silently_command): New commands
2476 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2478 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2479 more parameters than it used to.
2481 * findvar.c (registers): Increase slop to 256 bytes, which should
2482 protect us against even most RISC machines with large register
2484 (locate_var_value): Move declaration inside related ifdef.
2486 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2487 throughout, to avoid throwing away buffered input from the board.
2488 (nindy_wait): Supply_register takes addr_of_value, not value.
2489 (i960_print_fault): Renamed from i80960_fault.
2490 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2491 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2493 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2494 we can set the PC in the call to proceed(). Unpush nindy_ops
2495 before pushing it on top, to avoid message to user. Eliminate
2496 commentary from Unix machines that just misleads here.
2497 (reset_command): Fix error message to suggest target command.
2499 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2501 Release 3.92.5 as frozen.
2503 Stabilize the merged release...with help from lint, Saber C,
2506 Everywhere: Add include files needed to declare return types
2507 of functions called.
2509 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2511 * breakpoint.h: Add undeclared breakpoint functions, and some
2512 functions for display handling since I couldn't think of a better
2515 * breakpoint.c (insert_breakpoints): Make code for disabling
2516 shared library bkpts more likely to work. It's used when we
2517 rerun a program and stop before the shared library has been
2519 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2520 cast from pointer, so it squeezes through catch_errors.
2521 (bpstat_stop_status): Fix logic broken some time ago. We now
2522 always create a bpstat if the stop address matches a breakpoint,
2523 even if we don't stop there -- just like the old code used to do
2524 before I got my fingers into it (sigh).
2525 (breakpoint_1): Print "ignore count" after "stop only if"
2526 condition, since that's how it actually works.
2527 (mention): Handle watchpoints as well as breakpoints.
2528 (watch_command): use set_raw_breakpoint and mention to do most
2529 of the work (and initialize all the fields!). Only pass one
2530 arg to parse_c_expression, since that's all it takes.
2532 * command.c (not_just_help_class_command): Rename arg to args
2533 since we ignore "unused argument" warnings on vars named "args".
2534 inflow.c (child_terminal_info): ditto.
2535 infptrace.c (kill_inferior): ditto
2536 main.c (catch_errors, version_info, quit_command, pwd_command,
2537 source_command, dump_me_command, editing_info,
2538 set_history_size_command, set_history, show_history,
2540 stack.c (locals_info): ditto
2541 target.c (target_files_info): ditto
2542 valprint.c (set_input_radix, set_output_radix): ditto
2544 * core.c: Remove old variables for handling core and exec file
2545 sections (data_start, data_end, stack_start, stack_end,
2546 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2547 text_end, exec_data_start, exec_data_end, text_offset,
2548 exec_data_offset, data_offset, stack_offset). They're
2549 superseded the more general build_section_table and
2551 (get_exec_file): Mention the `file' command.
2552 (read_memory_check): Rename to memory_error, and only call it
2553 in the case of an actual error.
2554 (read_memory, write_memory): call memory_error.
2555 (core_fetch_registers): Register section name is ".reg".
2557 coredep.c: Remove a bunch of crud now that all this file does
2558 is pull the registers out of a core file.
2559 (fetch_core_registers): Rewrite to actually work, I hope.
2561 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2562 Replace index() with strchr(). Remove all the pre-BFD macro
2563 definitions for accessing the symbol file.
2564 (struct dbx_symfile_info): Encapsulate the information that
2565 dbx_symfile_init needs to pass to dbx_symfile_read in this
2568 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2569 dbx_symfile_discard): Rearrange symbol file reading to divide
2570 the format-specific part from the format-independent part,
2571 leaving the format-independent part such as file name expansion
2572 and opening in symtab.c. This replaces
2573 partial_symbol_file_open and partial_symbol_file_read.
2574 Symbol_file_read, add_file, add_file_target_command,
2575 add_file_addr_command move to symtab.c. Pass an explicit
2576 "mainline" flag for when reading the main symbol table, rather
2577 than relying on the offset address to be zero or nonzero.
2579 (dbx_symfile_read): Don't allow void *'s to be printed as
2581 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2582 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2583 macro" debug version really work.
2584 (read_dbx_symtab): Remove unref'd parameter inclink.
2585 Avoid swapping N_SLINE symbols, for speed.
2586 Merge N_TEXT!N_EXT case with the other external symbol
2587 definitions' case. Add comments.
2588 (start_psymtab): Allocate the symfile name in the psymtab on
2589 the psymbol_obstack, rather than using the caller's storage.
2590 (end_psymtab): Only allocate a dependencies list if there are
2592 (psymtab_to_symtab_2): Use BFD when reopening file to read
2593 its symbols for real.
2594 (read_struct_type): Add FIXME comments where it needs work
2596 (read_huge_number): Add FIXME about overflows.
2597 (read_range_type): Add FIXME about comparing a long to 1<<32.
2599 * coffread.c: Minor changes to move things closer to the new
2600 regime with symtab.c and dbxread.c Major work is still needed
2603 * exec.c (exec_file_command): Remove old variables (see core.c
2605 (xfer_memory): If memory transfer is right at the end of a
2606 section, don't lose.
2608 * findvar.c (get_saved_register): If value is in a real
2609 register, LVAL is lval_register, not lval_memory.
2611 frame.h: Declare print_sel_frame and record_selected_frame.
2613 gdb-int.texinfo: New file, for GDB internals documentation.
2614 Very simple, unformatted doc of cleanups is there for now.
2616 gdbcore.h: Remove obsolete variables that described a.out
2617 section addresses and offsets. (See core.c above.)
2618 Declare fetch_core_registers and registers_fetched.
2620 getopt.c: Declare char *alloca(); even on SPARC.
2622 infcmd.c (run_command): Call target_kill rather than
2624 (step_command, next_command, stepi_command, nexti_command):
2625 Declare from_tty parameter even though we don't use it.
2626 (run_stack_dummy): argument BUFFER is a char array, not
2627 a pointer to REGISTER_TYPE.
2628 (finish_command): using_struct_return needed a value *,
2629 not a struct symbol *.
2631 * infptrace.c (child_xfer_memory): To avoid dependency on
2632 where sections are in memory, try PT_WRITE_D and if that fails,
2633 try PT_WRITE_I. Most Unixes don't care which you use.
2635 * infrun.c (step_resume_break_shadow): Change to array to
2636 match other breakpoint shadow storage.
2637 (clear_proceed_status): Pass address of bpstat to
2638 bpstat_clear, not the bpstat itself.
2639 (child_create_inferior): FIXME comment about if the child
2641 (start_inferior): Remove old function.
2642 (child_open): Use target_kill rather than kill_inferior.
2643 (wait_for_inferior): Ditto.
2644 (insert_step_breakpoint, remote_step_breakpoint): Use
2645 new step_resume_break_shadow.
2647 * inftarg.c (child_wait): If all child processes die,
2648 pretend that the one being waited for exited with signal 42.
2650 * main.c (command_line_input): When scanning for comments,
2651 don't coredump on unclosed quotes.
2652 (quit_command): Use target_kill rther than kill_inferior.
2653 (_initialize_main): Rename class_user from "user" to
2656 * printcmd.c (print_command_1): Initialize "fmt" if no format
2657 is specified by the user.
2658 (print_frame_args): Only add to args_printed if we are
2659 actually fetching args from the stack (avoiding undefined
2661 (_initialize_printcmd): Remove bogus \{ from string.
2663 * remote-eb.c (eb_open): Avoid coredump on no argument.
2665 * remote-nindy.c: Bring out of Intel environment into new
2666 target environment. Remove all conditional compilation on
2667 I80960. Massive hacking throughout.
2668 (nindy_xfer_inferior_memory): New routine stolen from
2670 (nindy_create_inferior): New routine pieced together, probably
2671 not quite working yet.
2672 (nindy_ops): New target_ops struct for nindy.
2674 * remote-vx.c: Use write_memory rather than target_write_memory
2675 to get error checking.
2676 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2678 (vx_create_inferior): Use target_terminal_ours...
2680 * signame.c (_initialize_signame): Always initialize, since
2681 we need the table for things other than psignal.
2683 * solib.c (solib_add): Use symbol_file_add, not add_file.
2684 (solib_address): Return boolean result rather than struct
2685 pointer which nobody else knows the type of.
2687 * sparc-tdep.c, valops.c: Use write_memory rather than
2688 target_write_memory, to get error checking.
2690 * stack.c (locals_info, catch_info, args_info,
2691 get_selected_block, frame_command, up_command): Use
2692 target_has_stack, rather than have_inferior_p or
2695 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2697 * symfile.h: New file, defining the interface between the
2698 generic and object-file-specific symbol reading code.
2700 * symtab.c: Move generic symbol-reading interface to symtab.c,
2701 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2702 table to map BFD targets to symbol-reading modules in GDB.
2703 Change index to strchr.
2704 (lookup_struct_elt_type): Use error() rather than hand-made
2705 simulations thereof.
2706 (lookup_partial_symbol): Speedup slightly when length == 0.
2707 (symbol_file_add): New function.
2708 (symbol_file_command): Call it.
2709 (symfile_open, symfile_init): New function.
2710 (add_file_target_command, add_file_addr_command): moved from
2713 * target.c (target_command): use target_kill.
2715 * target.h (target_files_info): Don't declare, never called
2718 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2719 files to determine stack end address.
2721 * valarith.c (value_x_binop, value_x_unop): Change error message
2722 to be more useful. Pass proper argument to value_struct_elt.
2724 * valops.c (value_assign): FIXME comment that long long
2725 bitfields will break here.
2727 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2728 Update `make saber_gdb' to work better.
2730 * TODO: A woman's work is never done.
2732 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2733 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2734 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2735 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2736 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2737 valops.c, valprint.c, exec.c: Lint.
2740 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2742 Continuing Intel 960 port merge of GDB.
2744 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2745 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2746 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2747 Wack over "make depend" so it handles files in subdirectories
2748 vx-share, nindy-share, bfd, and in the current directory.
2750 * blockframe.c (get_prev_frame_info): Remove fatal error
2751 if stack not defined.
2753 * core.c (core_open, core_detach): New functions that handle
2754 the old "core-file" command as "target core" and "detach" instead.
2755 (core_file_command): Call them.
2756 (core_xfer_memory): Use common routine xfer_memory.
2758 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2759 dbxread now uses bfd for everything but symbol reading itself.
2760 BFD internals are used to drag out the relevant file offsets.
2761 (partial_symbol_file_open): Change args all around for BFD.
2763 * symtab.c: Rename "value" to "val" everywhere, so we can
2765 (symbol_file_command): New command, moved from dbxread.c
2766 and coffread.c. It uses BFD to read the file, then vectors
2767 based on its type, to dbx or coff symbol readers.
2768 * symtab.h: Extern a few vars for symbol_file_command.
2770 * target.h: Breakpoint takes a char * save area, not a char **.
2772 * valprint.c (val_print): When unpacking bitfields, offset
2773 the address in gdb of the value, if it is declared with a shorter
2774 type. Remove the last "runtime kludge test" of host byte order.
2776 * utils.c: Remove old my_bfd_read routine.
2778 * stack.c (frame_info): Use target_has_stack. Print program counter
2779 register's actual name rather than "pc", since it's called the
2780 "ip" (instruction pointer) on the i960 (sigh).
2782 * target.c (target_command): Add command for selecting a target
2783 type and calling its open routine. This is used for initiating
2784 communication with a particular target, in a generic way.
2786 * tm-i960.h: Update for modern gdb. Remove semicolons from
2787 various macros. Handle reading struct return convention, and
2788 error-out attempts to return structs with the "return" command.
2789 Be sure gdb doesn't think we know how to call functions in the
2792 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2793 to i960_xxx in lower case.
2794 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2795 not being defined yet.
2797 * remote.c (remote_open): Call start_remote to initialize
2798 wait_for_inferior during open.
2799 (remote_xfer_inferior_memory): Return length written rather
2802 * remote-vx.c (target_command -> vx_open): Use new generic
2804 * remote-eb.c, inftarg.c, exec.c: ditto.
2806 * infrun.c: Fix comments.
2807 (attach_program -> child_open): Use new generic target command.
2808 (wait_for_inferior): Clear saved register values before target_wait,
2809 so target_wait can set some of them if convenient.
2811 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2812 Return success indicator, not void.
2813 (child_xfer_memory): Avoid fetching initial word if we'll
2814 overwrite it anyway.
2816 * infcmd.c (attach_command): Use new generic target open routine.
2817 (_initialize_infcmd): Update doc on attach and detach commands.
2818 (do_registers_info): Merge in a byte-order problem as a FIXME
2821 * findvar.c (find_saved_register): Avoid problem in current frame.
2822 (read_relative_register): Ditto.
2823 (write_register): Convert byte order on the way out.
2825 * exec.c (file_command): Add.
2826 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
2827 (xfer_memory): Common function between core_xfer_memory and
2829 (exec_xfer_memory): Use it.
2831 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
2833 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
2834 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
2835 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
2837 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
2839 Merge Intel 960 port of gdb, continuing...
2841 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
2842 symbol_file_command): Pass from_tty arg to hush 'em up.
2844 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
2845 Add magic numbers for 960 COFF format.
2847 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
2849 Merge Intel 960 port of gdb, from Intel "1.2" release.
2851 CHANGE_LOG entries from their port, which was based on

2855 Remove temp file if download is interrupted.
2857 Wed Aug 1 09:08:33 PDT 1990
2858 Now uses binary protocol to talk to NINDY.
2859 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
2860 Times out after 5 seconds when trying to talk to NINDY.
2862 Tue May 29 12:54:49 PDT 1990
2863 Added variable baud rate (-b switch).
2864 Source code reorganization.
2866 Thu Apr 26 11:09:55 PDT 1990
2867 More cleanup of batch mode; specifically, execute "-s", "-e", and
2868 "-se" switches as soon as they are encountered on the invocation line.
2870 Fri Apr 20 13:47:15 PDT 1990
2873 Thu Apr 19 09:54:28 PDT 1990
2874 Add 'reset' command.
2876 Wed Apr 18 09:48:07 PDT 1990
2877 After opening remote tty, wait for 1 second to go by without input
2878 from it before trying to talk to NINDY (fixes problems with the
2879 Heurikon HK80/V960E).
2881 Mon Apr 4 16:33:05 PDT 1990
2882 Some output was not being suppressed in 'batch' mode.
2884 Thu Mar 22 15:31:11 PST 1990
2885 Ask user if old symbol table should be deleted when new file is
2888 Allow user to run a program downloaded before gdb960 was brought up.
2890 Correct "exec-file" help message for i80960 context.
2892 Correct bug in calculating user space address: could occasionally
2893 corrupt user program.
2895 Make sure to zero low-order bits in rip's because of bug in 960CA
2896 A-step part: could cause operation faults when "next"ing across
2899 Correct bug that made it impossible to get source line numbers for
2900 code loaded at addresses higher than 0x7fffffff.
2902 Wed Jan 10 12:43:22 PST 1990
2903 Open remote tty for exclusive use.
2905 Fri Jan 5 12:14:42 PST 1990
2906 Correct disassembly (CA manual was right after all):
2907 opcode for sysctl is 0x659
2909 Mon Oct 23 12:03:04 PDT 1989
2910 Use G960BASE and G960BIN environment variables to find 'sx' utility.
2912 Mon Oct 16 14:15:09 PDT 1989
2913 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
2915 Mon Oct 2 15:56:31 PDT 1989
2917 Added 960CA disassembly support.
2919 To simplify maintenance:
2920 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
2922 - eliminated opcode.h: incorporates tables into i960-pinsn.c
2923 - moved 960-specific routines from i960-pinsn.c to i960-md.c
2924 - made disassembly interface identical to that in gdmp960.
2928 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
2930 * target.h: Allow targets to stack. Add target_has_memory,
2931 _registers, etc. Restructure memory access and "info files"
2932 to walk the target stack.
2933 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
2934 target.c: Change tables to match target.h.
2935 * inflow.c (child_mourn_inferior): pop child_ops.
2936 (generic_mourn_inferior): Use new has_stack flag.
2937 * infptrace.c (child_xfer_memory): New memory regime.
2938 * inftarg.c (child_files_info): New "info files" regime.
2939 * remote-eb.c: New memory regime, new info files.
2940 * remote-vx.c: New memory regime, new info files. Now use
2941 separate targets for VxWorks attachment to machine, and
2942 actually running a process under VxWorks, since one has
2943 stack & execution & regs and the other doesn't.
2944 * remote.c: New memory regime, new info files.
2945 * sparc-xdep.c (fetch_core-registers): New memory regime.
2946 * target.c: New routines and support for stacked targets,
2947 new memory regime, new info files regime.
2950 Generalize section handling for an arbitrary number of sections,
2951 including use of the new BFD (binary file) library.
2952 * gdbcore.h: Add struct section_table.
2953 * exec.c (build_section_table): Iterate all sections and
2954 record what gdb needs to know about them.
2955 (exec_command): Use it.
2956 (exec_xfer_memory): Use the table.
2957 (exec_files_info): Print the table.
2958 * core.c (core_file_command, core_xfer_memory, core_files_info):
2960 * source.c (find_source_lines): Use bfd_get_mtime.
2961 * dbxread.c: Quick changes to make it compile with new BFD.
2962 * utils.c (error): Avoid using bfd_error in generic routines.
2964 * core.c (core_fetch_registers): Get from the ".regs" section of
2966 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
2968 * inferior.h (attach_flag): Export.
2969 * infcmd.c (run_command): use new target_create_inferior.
2970 * infrun.c (child_create_inferior): Don't return result.
2971 * Makefile.dist (VERSION): 3.91.4.
2973 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
2975 * breakpoint.c (bpstat_num): Handle breakpoints which have
2976 since been deleted, such as temporary breakpoints.
2977 infcmd.c (program_info): ditto.
2979 * core.c (core_file_command): Display the frame where the core
2984 * remote-vx.c (target_command): Merge in target command from
2985 targ-vx.c. A few other cleanups.
2987 * TODO, Projects: Lots more stuff to do...
2989 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
2991 Massive changes to wall off the remote-debugging interface
2992 behind a function vector. The port to handle VxWorks targets
2993 is also part of this.
2995 All files: Replace references to renamed functions,
2996 remove references to remote_debugging, remove references to
2997 have_include_file, have_core_file in favor of target_has_stack,
2998 target_has_memory, etc.
3000 * Modularize the breakpoint interface.
3001 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
3002 a breakpoint instruction.
3003 breakpoint.c: struct breakpoint's shadow_contents now sized as
3005 (insert_breakpoints): Vector to target to install breakpoints.
3006 (remove_breakpoints): Vector to target here too.
3007 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
3008 sparc-tdep.c (single_step): Use new breakpoint interface for
3009 the single-step breakpoints.
3010 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
3011 New file, contains routines to insert and remove breakpoints by
3012 reading out the old contents and later replacing them. This is
3013 how ptrace breakpoints work, and many remote systems as well.
3015 * tm-vxworks68.h: New config file, overrides a few things for
3016 Wind River's preferences.
3018 * target.h: New file, for transfer vector used to talk to the
3019 inferior (child, attached, core, exec, remote, etc). All accesses
3020 to the thing being debugged should come through these vectors.
3021 target.c: New file, routines to handle transfer vector.
3022 (various files): Add transfer vectors XXX_ops for the various
3023 targets and pseudo-targets (core files, etc) we support.
3025 * breakpoint.c (bpstat_stop_status): Further explorations of
3026 watchpoints and why things don't work all the time.
3027 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3029 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3030 the local gdbinit if it doesn't already have it.
3032 * core.c (core_ops): add and install.
3033 Allow core debugging without exec file.
3035 * dbxread.c (free_and_init_header_files): Merge two fns.
3036 (end_symtab): Free named symbol table when a new version comes in.
3037 (read_dbx_symtab): Relocate all kinds of symbols with base
3038 address. First step toward handling different text, data, bss
3040 (add_file_addr_command): Renamed add_file_command.
3041 (add_file_command): Vector to remote handler.
3042 Add "load" as an alias for "add-file" command.
3044 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3045 non-returning functions.
3047 * exec.c: Add exec_ops, and push it as a target when an exec
3050 * infcmd.c (run_command): Pass executable file name and arg list
3051 separately when starting an inferior. Permit "run" when no exec
3052 file is specified, for VxWorks.
3053 (detach_command): Move to child_detach in inftarg.c.
3055 * inftarg.c: New file. Unix-child-specific routines, and the
3056 child_ops structure.
3058 * inferior.h (registers): Export "registers" as the way for
3059 target dependent register handlers to find gdb's local copy of
3060 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3061 since it is now used by places that want wait_for_inferior to
3062 handle the grunge but want to see every trap from the inferior.
3064 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3065 Eliminate remote_debugging hooks in terminal handling.
3067 * infrun.c: Replace start_inferior with child_create_inferior.
3068 Move all the hair of Unix shells and ptrace idiosyncracies into
3069 child_create_inferior, so remote handlers don't have to deal.
3070 Remove running_in_shell. Rename stop_after_attach to
3071 stop_soon_quietly, and use it in a few other places where we want
3072 to just call wait_for_inferior and get control back on the first
3073 trap. trap_expected now never takes a value > 1.
3074 (init_wait_for_inferior): Initialize static vars when a new
3077 main.c (gdbinit): Add new hook for .gdbinit file name, let
3078 it be overridden by config files as GDBINIT_FILENAME.
3079 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3080 Both of these are used for VxWorks gdb.
3082 mcheck.c: rename include file "gmalloc.c" to avoid problems
3083 with system include file "malloc.c".
3085 param-no-tm.h: New include file, same as param.h but does not
3086 include the default "tm.h" file. This is used in files where
3087 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3089 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3091 remote-vx.c: New file, VxWorks remote debugging support. Uses
3092 RPC routines that are shared with the target system, in directory
3095 remote.c: Vectorize remote interface.
3097 source.c: Globalize source_path, and make an alias "l" for "list"
3098 since we now have the "load" command.
3100 sparc-xdep.c: Use new param-no-tm.h.
3102 symmisc.c (free_named_symtab): Add new function from Wind River.
3103 However, ifdef it out for now while we think about what it should
3106 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3108 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3109 non-Unix-children handle this with their own code in the target
3112 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3113 source and target lists. Add vx-share to default list of include
3114 directories. Add new files to src and target lists: mem-break,
3115 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3116 ${srcdir} versions of munch and createtags are used.
3118 * valops.c (find_function_addr): Split out of call_function.
3119 (call_function_by_hand): Rename call_function; this function
3120 calls functions in the target by laboriously patching the target
3121 word-by-word with the right stack, args, regs, etc.
3124 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3126 Handle AMD 29000 a bit better.
3128 * remote-eb.c (readchar): Mask received char log to make it readable.
3129 (remote_start): Pass arguments down to executing program.
3130 Make startaddr unsigned.
3131 infrun.c (start_inferior): Accept args, pass them to
3133 infcmd.c (run_command): Pass args down to start_inferior.
3135 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3136 the target object file format.
3137 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3139 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3140 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3142 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3144 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3145 * TODO: We did a few things, we have more to do though.
3147 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3148 * inflow.c (inferior_died): Clear deferred stores.
3150 * Debug problems with dummy frames and calls to the inferior.
3151 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
3152 * sparc-tdep.c (do_restore_insn): Simplify.
3153 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3154 (sparc_push_dummy_frame): Simplify and fix what we push.
3155 (sparc_pop_frame): Slightly more hair here, deciding whether
3156 we are restoring a saved PC or returning to a return address in %i7.
3157 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3159 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3160 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3161 * obstack.h (chunkfun): ditto.
3162 * defs.h (xmalloc, xrealloc): ditto
3164 * utils.c (quit): Grab the terminal from the child if necessary.
3166 * inflow.c (term_status_command): Rename to term_info, change
3169 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3170 (is_delayed_branch): Speed up.
3171 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3172 Still missing some float ops, and needs testing.
3174 * Support for input and output radixes other than base 10
3175 * defs.h (input_radix, output_radix): Declare.
3176 * expread.y (yyparse, parse_number): Handle changes of input
3177 radix, and ambiguous names-or-numbers in radixes >10.
3178 * printcmd.c (print_scalar_formatted): Print formatted hex
3179 numbers in varying column widths.
3180 * valprint.c (val_print): Use output_format to print scalar ints.
3181 (set_input_radix, set_output_radix, set_radix): Create.
3182 (set_output_radix): Set output_format from output_radix.
3183 (_initialize_valprint): add `set radix' but leave the others off.
3185 * main.c (execute_command): Let stupid questions be turned off.
3186 (_initialize_main): Handle "set stupidity", etc.
3188 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3189 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3191 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3193 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3194 bfd stuff is still screwed up, but with some manual work, it
3197 * breakpoint.c (bpstat_do_actions): Start over if a command
3198 proceeds the inferior, since the inferior will have stopped and
3199 will need to have its new stop-actions taken care of.
3201 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3202 compiler fits, simplify it.
3204 * gdb.texinfo (directory command): Doc new dir command.
3205 source.c (directory_command): "dir" now puts things on the front
3206 of the path, moves dups up front, and handles multiple names
3207 on the command line, inserting each one in order. It also
3208 blows away cached line and full_filename info.
3210 * stack.c (backtrace_command): Skip "more stack frames follow"
3213 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3214 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3215 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3216 The only odd one was Gould NP1, which had defined vprintf to
3219 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3220 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3221 variable, inspect_it.
3222 valprint.c (print_string, val_print): Use the global inspect_it
3223 to indicate whether to print in Epoch style or normal style.
3225 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3227 * printcmd.c (call_command): add an alias for the "print" command
3228 which runs expressions and doesn't print the result if void.
3229 (print_command_1): implement it.
3231 * command.c: Remove #if 0'd code. Initialize all the fields
3232 in add_cmd (). Rename do_nothing_command to
3233 not_just_help_class_command, and make it externally visible.
3234 command.h: add user_commands to struct.
3235 * main.c (define_command): Don't overload c->function with a char
3236 string as well as a function pointer.
3238 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3239 calling convention of value_struct_elt () that got dropped in
3242 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3243 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3245 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3247 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3248 until a good time (e.g. when we are about to run the child),
3249 saving ptrace calls.
3250 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3251 * tm-sparc.h: define DO_DEFERRED_STORES.
3253 * sparc-xdep.c (store_inferior_registers): when storing float
3254 registers, don't store stack regs too. When storing the SP,
3255 however, DO store the stack regs too. This fixes a bug in which
3256 the dummy frame is not recognized when a call_function finishes,
3257 because its frame pointer (in the stack regs) was never
3259 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3260 even though we don't know how to read them from an inferior.
3261 valops.c (call_function): Comment about storing SP.
3263 * infrun.c (save_inferior_status): Save away the original bpstat
3264 chain so it can be restored later. Install the copied version for
3265 use by whoever saved the status. It will be blow away by
3266 restore_inferior_status, and the original chain restored. This is
3267 important for people who have pointers into the original.
3269 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3270 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3271 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3274 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3276 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3277 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3278 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3280 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3282 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3283 Store the baseclasses in a type struct starting from array element
3284 0 rather than from the unusual array element 1.
3286 dbxread.c: the above.
3287 (virtual_context): Add
3288 Read new debug information about which virtual function table
3289 a virtual function is from, and store it in fn_field.fcontext.
3291 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3292 TYPE_FN_FIELD_STATIC_P.
3294 symtab.c: the above.
3295 valops.c: the above. Handle pointer casts of object *'s.
3296 (search_struct_method): Add.
3297 (value_struct_elt): First arg is now a pointer to a value, and is
3300 valprint.c: the above.
3301 values.c (value_virtual_fn_field): Add type arg. Handle
3302 offsetting to the proper object when calling virtual fns.
3304 (baseclass_addr): Add valuep arg.
3306 * README: Document the current state of BFD config (missing).
3307 * TODO, ChangeLog, Makefile.dist: Roll version.
3308 * WHATS.NEW: Add summary of changes since 3.5.
3310 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3312 * dbxread.c (read_struct_type): Clear bit vectors whenever
3314 symtab.c (B_CLRALL): define.
3316 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3317 using == rather than =. Huh... This fixes the dreaded problem
3318 wherein builtin_type_int becomes TYPE_CODE_FLT.
3320 * core.c (info_files): Show the inferior pid.
3322 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3323 already knows how to look in the source directory.
3325 * Remove psymtab hair from many places. Remove duplicated code
3326 for searching symbol tables. Hide psymtabs from most places.
3327 Make it fast to get from a psymtab to its symtab.
3329 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3330 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3331 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3332 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3333 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3334 new symtab completely. New psymtabs get symtab pointer
3335 initialized to zero. Remove MI warning printf.
3336 symtab.h: Comments. Add psymtab to symtab pointer.
3337 (PSYMTAB_TO_SYMTAB): New macro.
3338 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3339 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3341 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3343 (print_frame_info): Avoid special-casing symbols that have not yet
3346 * source.c (open_source_file): Quick path if we have already
3347 located the source file by its full name.
3349 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3350 find_pc_psymtab. When a name is found in the misc function
3351 vector, search the symbol table for its mangled name, not the
3352 name that the user typed.
3354 * bfd.h: Fix missing comment terminators, make #endifs match.
3356 * valarith.c (value_less): Handle unsigned int comparisons.
3357 Add FIXME about pointer compares, which assume host and target
3358 pointers are the same.
3360 * command.c (do_nothing_command): lint
3361 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3362 fix comments on debug symbol format for visibility. Actually set
3363 visibility of symbols.
3364 main.c (echo_command): lint; use <readline/history.h>.
3365 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3366 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3367 pointing past end of allocated memory; saber complains.
3368 obstack.h: Declare the external functions that we use.
3369 valarith.h: use <string.h>
3370 solib.c (solib_add): lint.
3372 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3374 * main.c (initialize_main): Default info_verbose to off, now that
3375 symbol reading is fast.
3376 (quit_command): Avoid clobbering exec_bfd while quitting.
3378 * Initial BFD (binary file diddling library) merger:
3379 coffread.c: Change AOUTHDR to struct exe_hdr.
3381 core.c: initialize initialized data at compile time.
3382 (core_file_command): Move from coredep.c, convert to bfd.
3383 (xfer_core_file): Convert to bfd.
3384 exec.c (exec_file_command): use bfd routines.
3386 mips-tdep.c: Remove exec_file_command and friends.
3389 * coredep.c: (fetch_core_registers) Convert core_file_command to
3390 fetch_core_registers.
3391 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3393 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3394 (my_bfd_read): More bogosity, which I don't think we call.
3395 (program_name): Remove this atrocity asap!
3397 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3400 values.c: allocate_repeat_value was not clearing the
3401 optimized_out field.
3402 (value_static_field): minor stylistic fix (wrong macro was used).
3403 valops.c (value_struct_elt_for_address): didn't work for C++
3406 * signame.c (_initialize_signame): Initialize signal names once.
3408 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3409 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3410 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3412 * remote-eb.c: Support user-settable baud rates on the serial port.
3414 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3416 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3418 * tconfig/sun3os4: Remove warning about native assembler,
3419 since it also occurs in the xconfig file.
3421 * findvar.c (registers): Allocate some slop after `registers'
3422 to prevent stray accesses from trashing the next variable.
3424 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3425 on the sun-3, by changing the #ifdef from `sun3' (which is not
3426 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3427 vars, which happened to follow `registers' in the executable.
3429 * readline/history.c (history_search): Heed gcc-2's advice
3430 and parenthesize && inside ||).
3432 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3433 tm-29k.c: Insert FSF copyright headers.
3435 * remote-eb.c: Better comments.
3437 * Makefile.dist: Update to 3.91.6.
3438 * TODO: note PREPARE_TO_STORE problem.
3440 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3442 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3444 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3446 * infrun.c (wait_for_inferior, at end): Don't set up
3447 prev_* if the inferior no longer exists.
3449 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3450 CANNOT_EXECUTE_STACK.
3451 valops.c (call_function): Use it.
3453 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3455 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3456 infrun.c (wait_for_inferior, 2 places): Use it.
3458 * values.c (value_being_returned): Only use
3459 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3461 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3462 right thing for remote-eb.c.
3464 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3465 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3467 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3468 (FRAME_FIND_SAVED_REGS).
3470 * findvar.c ({fetch,store}_registers): Check for
3471 REMOTE_{FETCH_STORE}_REGISTER macro.
3473 * findvar.c (get_saved_register): Add argument lval and
3474 change meaning of argument addr.
3475 findvar.c: Change calls to get_saved_register to reflect
3476 new calling convention.
3477 valops.c (value_assign): Use get_saved_register instead of
3478 find_saved_register.
3480 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3482 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3483 an (uninitialized) pointer to one. Use "&" when passing it
3486 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3488 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3491 * coffread.c (symbol_file_command): Put semicolon after
3493 Put safe_to_init_tdesc_context in #if defined (TDESC).
3494 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3495 coffread.c: #include <sys/stat.h>.
3496 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3497 Add missing ')' in check for "lc%" and friends. Remove
3499 Declare read_one_sym() at top of file.
3500 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3501 MC68WRMAGIC can have the same value without causing a duplicate
3504 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3506 * Allow a Makefile to be built without building the
3507 tm and xm file links that screw up builds in subdirectories.
3508 This is done with `config.gdb none', then you can do things
3509 like `make gdb.tar.Z'.
3510 * tconfig/none: Config file for no target system
3511 * xconfig/none: Config file for no host system
3512 * config.gdb: If no TM or XM files are called out by the
3513 host or target file, don't make links for them.
3515 * cplus-dem.c: Add documentation.
3517 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3518 simple error, so the user's gdb doesn't crash due to some object
3519 file problem (e.g. somebody is rebuilding the file out from under
3522 * printcmd.c (print_address_symbolic): demangle the symbol.
3524 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3525 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3526 (alldeps.mak): sort and uniq all results from this; duplicates
3527 hose gdb.tar.Z link building. Remove RCS files from
3528 tconfig and xconfig. Add config files for sun386. Add
3529 a few odd files to OTHERS and HFILES.
3531 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3533 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3534 Roll version number to 3.91.5. Make lint work in bindir.
3536 * README: Document cross-debugging and new file structure.
3538 * blockframe.c: Lint. Include "value.h" to declare read_register.
3539 (find_pc_partial_function): remove duplicate line.
3541 * command.h: Lint. Declare error_no_arg and dont_repeat.
3543 * tm-news.h: Remove inadvertently duplicated stuff.
3545 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3546 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3548 * config.gdb: Allow `config.gdb host target' form. Clean
3549 up previous change that printed bogus messages when you just said
3552 * core.c: #include "command.h" for lint.
3555 * main.c: Remove some casts of enums. Lint.
3562 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3564 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3565 read it from memory. This will allow us to save ptrace calls
3566 eventually. Changed caller single_step too.
3568 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3569 that we aren't going to use, saving many ptrace calls, especially
3570 when watchpointing or single stepping. Use some #define's for
3572 (store_inferior_registers): Ditto.
3573 (core_file_command): Use some #define's for constants.
3575 * tm-sparc.h: Add #define's for some register numbers, so we
3576 can eliminate the use of random constants in sparc-xdep.c.
3578 * stack.c (frame_command, print_frame_info, up_command,
3579 down_command) Remove frame_changed, since it
3580 causes a bug and doesn't seem to do anything useful. In some
3581 places it was used as a flag, in others as a stack level (?).
3583 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3584 default is to use the portable (vprintf) version rather than the
3586 * xm-news.h (MISSING_VPRINTF): Add.
3588 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3590 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3592 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3593 about linking debugged programs -Bstatic in the sun?os4 config
3594 files in tconfig and xconfig subdirectories.
3596 * main.c (main): Remove unreached exit(0) now that we exit
3599 * Create TODO file for online bug list. There are too many
3600 "little" bugs to keep track of on paper.
3602 * Change Projects file to refer to bug-gdb@cygnus.com
3603 rather than kingdon@ai.
3605 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3607 * Makefile.dist (VERSION): 3.91.4 now.
3609 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3610 (condense_misc_bunches): Add sanity check that misc_count is
3611 the same as the number of symbols in the bunch.
3613 * coffread.c: rename init_misc_bunches. Pass an argument
3614 to condense_misc_bunches (a zero).
3616 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3617 every time we are called; don't rely on our caller to do it.
3618 (add_file): Remove call to init_misc_bunches.
3620 * mipsread.c: Only warn, don't error, if unknown symbol types.
3621 This keeps an old gdb from falling on its face if it sees newly
3622 extended symbol info. Rename init_misc_bunches.
3624 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3626 * Merge in changes from Per Bothner for DECstations and other
3627 MIPS stuff. The rest is Bothner speaking:
3629 The next message is a merger of Alessando Forin's mips port with
3630 mine. I've tried to use my good if biased judgment to get
3631 the best of both. It *does* need testing.
3633 Some of the changes are general, *not* mips-specific.
3636 Didn't believe in little-endian bit order.
3637 There are still inconsistencies about whether flags
3638 like BITS_BIG_ENDIAN are integer (#if ...) or
3639 boolean (#ifdef ...). I tried to paper over them.
3641 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3642 Moved some misc_function code that was common to
3643 {dbx,coff,mips}read.c to symtab.c.
3644 In the process, I think I cleaned things up a bit.
3645 At the same time, moved obsavestring and obconcat to symtab.c.
3648 Removed obsolete condense_addl_misc_bunches (use
3649 condense_misc_bunches(1) instead).
3652 Needed to include <sys/dir>, at least on DECstations.
3654 valops.c, mips-tdep.c, tm-mips.h:
3655 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3656 conventions (when STACK_ALIGN is insufficient).
3657 Needed on mips, where doubles need 8-byte alignment,
3658 but ints only need 4.
3661 Removed cruft that was not being used.
3662 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3665 Print $ before register-names (I think that makes things a little
3667 Never print two instructions, even if one delays.
3668 Removed hex-disassemble set_cmd. (This is not mips-specific,
3669 so I think the argument is whether it is generally worthwhile or not.
3670 I'm inclined to think not, given how easy it is to
3671 convert between radixes in gdb.)
3674 This is basically Alessando's code.
3675 It doesn't use obstacks; I changed it to use obstacks
3676 in a few minor places where using malloc causes a
3677 memory leak. (Probably, more places could/should be changed.)
3678 I added record_misc_function where it was missing.
3679 In symbol_file_command and add_file_command, I tried
3680 to make the code consistent with more recent versions.
3681 Minor sylistic changes in parse_procedure.
3682 Make a .gdbinfo. psuedo-symbol point back to the real
3683 procedure symbol (using the isym field).
3686 This is basically from my port, but with a lot of details
3687 and a number of routines merged in from Alessando's version.
3688 I basically used my code "raw" backtrace (use heuristics
3689 from the actual code, rather than symbol table info) - though
3690 the idea is Alessandro's. I feel my code is a little cleaner
3691 here, particularly in being a little more flexible, such as being
3692 able to handle gcc-produced code (which it now can).
3693 It also doesn't do frame caching (which is not useful
3694 more recent gdb versions).
3695 I also used my code for push_/pop_dummy, more or less.
3696 I tried to incorporate AF's code for testing sigtramp
3697 while backtracing; I probably got it wrong.
3698 Added mips_print_register, which tries to scrunch as much
3699 information as possible on a screen...
3700 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3701 under mips-pinsn.c), I don't see anything mips-specific here,
3702 and I don't see it being all that useful anyway.
3705 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3706 Use more register names (rather than hard-cases numbers).
3708 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3710 * Hack up 3.90.11 changes:
3712 * Makefile.dist (depend): parameterize $(GCC).
3713 Add solib.c and solib.o.
3714 (readline): Fix vpath for both absolute or relative SRCDIR.
3716 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3717 Also, let the part I didn't understand at least compile so
3718 I can test the rest. FIXME.
3720 * dbxread.c: Fix thinko using strcmp.
3721 (init_psymbol_list): declare static.
3722 (partial_symbol_file_open): Comment cleanups better, avoid
3723 cleaning up the string table since the caller will do that.
3724 Move the stat for mod time into symbol_file_command, temporarily.
3725 (There should be a mod time for each symbol file, eventually,
3726 to control its rereading. FIXME.)
3728 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3729 SunOS, which gives error for shared libs otherwise. (From
3730 Schaefer, probably FIXME needs work for portability.)
3732 * solib.c: Move #include "param.h" to work.
3733 Lowercase all the Uppercase Letters In the Messages.
3734 (find_solib): Clean up inferior_so_name for debug printouts.
3735 Allow no argument, to mean all shared libraries.
3737 * symmisc.c: include param.h to get CLEAR_SOLIB.
3739 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3741 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
3742 to 3.90.11. ChangeLog entries below are from this.
3744 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3748 * Makefile.dist (HFILES): Add tm-sunos.h.
3750 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3754 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
3756 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
3758 * sparc-opcode.h Added single-operand version of rett.
3760 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3762 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
3763 Put parens around gcc_p in expansion.
3765 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3767 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
3769 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3771 * Changes for Sun shared libraries:
3772 blockframe.c (find_pc_partial_function): If a non-text symbol
3773 is found, set *address = pc - FUNCTION_START_OFFSET.
3774 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
3775 Disable breakpoints instead of giving an error.
3776 source.c (select_source_symtab): Initialize cs_pst.
3777 symmisc.c: Call CLEAR_SOLIB if defined.
3778 symtab.h: Make text{low,high} CORE_ADDR not int.
3779 (psymtab): New field addr.
3781 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
3782 (record_misc_function): Give correct type for N_DATA symbols.
3783 (condense_misc_bunches): do "misc_function_count = j" regardless
3785 Take code which is shared between symbol_file_command and
3786 add_file_command and put it into partial_symbol_file_{open,read}.
3787 Split add_file_command into add_file_command and add_file.
3788 Make psymtab_to_symtab read in the string table if the file
3790 Two new parameters to read_dbx_symtab and start_psymtab.
3791 tm-sunos.h: New file.
3793 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3795 * infcmd.c: Change cont_command to continue_command and "cont"
3798 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3800 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
3802 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
3804 * values.c (USE_STRUCT_CONVENTION): Check for structures of
3805 size 1,2,4,8 rather than size < 8.
3807 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
3808 as necessary, not just once.
3810 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3812 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3814 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3816 * tm-news.h: Add CALL_DUMMY_*.
3818 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
3820 * config.gdb: In list_host, list_target, use ${i}, not $i.
3822 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3824 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
3826 * sparc-opcode.h: Change all store floating-point state register
3827 instructions to have the right match & lose fields.
3829 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3831 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
3833 config.gdb: If srcdir != ., create readline directory and
3834 copy a makefile into it.
3836 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
3837 consistency with POSIX.
3839 * breakpoint.c (bpstat_stop_status): Disable watchpoint
3840 when we exit its exp_valid_block.
3842 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
3844 * Makefile.dist: Bump version to 3.91.3.
3846 * Clean up handling of breakpoint commands (somewhat).
3847 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3849 inferior.h: Add breakpoint_proceeded to inferior status struct
3850 and globals; save it and restore it.
3851 (clear_breakpoint_commands): Cleanup, remove old #define.
3853 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3854 (save_inferior_status, restore_inferior_status): handle it also.
3855 (proceed): Remove earlier code that set breakpoint_proceeded.
3856 It is now set only in clear_proceed_status.
3857 (clear_proceed_status): Cleanup, use bpstat_clear rather
3858 than clear_breakpoint_commands. No callers need the stop_bpstat
3859 between clear_proceed_status and proceed.
3861 infcmd.c: Add breakpoint_proceeded definition and comment.
3862 (cont_command, jump_command, signal_command): Move call to
3863 clear_proceed_status right next to call to proceed.
3865 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3866 caller's argument while running down the chain of breakpoints.
3867 Use new variable "breakpoint_proceeded" to determine when
3868 a command that it executes moves the inferior past the
3870 (bpstat_clear): Handle NULL argument.
3871 (bpstat_clear_actions): Avoid useless call to
3872 breakpoint_auto_delete.
3873 (delete_breakpoint): Clean up bpstat's that are pointing to
3874 the deleted breakpoint from the stop_bpstat chain.
3875 (breakpoint_auto_delete): Simplify.
3877 * Clean up handling of EOF, error on stdin, etc. This was
3878 prompted by a network problem that caused gdb to go into an
3879 infinite loop filling up its malloc'd memory.
3881 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
3882 not clear_breakpoints_commands, which is now gone.
3883 (main): If command_loop returns (e.g. from EOF on stdin), do
3884 a quit_command (looping back to command_loop if quit_command
3885 doesn't really quit).
3886 (command_loop): check result from command_line_input and
3887 exit if it returns NULL, rather than passing the NULL to
3889 (gdb_readline): Free malloc'd result space before returning
3892 * utils.c (query): Handle C-d to mean "yes", just as if the
3893 input was not a terminal. Also avoid infinite loop if EOF
3894 occurs in mid-input-line before newline. This allows
3895 query to be used at EOF on stdin with reasonable results.
3897 * infrun.c (proceed): Set breakpoint_proceeded.
3899 * values.c (value_as_long): Avoid infinite recursion for enums.
3900 (_initialize_values): Fix typo in help msg (kingdon).
3902 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
3903 RL_LIB for linking. This allows -lreadline for linking
3904 and nothing for dependencies, once readline is a real library.
3906 * config.gdb: Jim Kingdon: give useful error message if the
3907 host or target type is not recognized.
3909 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
3910 it just defines it. Dumb, but deal with it.
3912 * Jim Kingdon suggests:
3913 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
3915 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
3917 * Makefile.dist (VERSION): Bump version # to 3.91.2.
3919 * Clean up Bothner's changes.
3921 * blockframe.c (clear_pc_function_cache): New function.
3922 * blockframe.c: remake cache_pc_function_* static.
3923 * dbxread.c (symbol_file_command): remove references to
3924 cache_pc_function_* variables.
3925 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
3926 * printcmd.c: Avoid kludging a global variable (addressprint)
3927 to avoid printing the address of a string twice. Instead,
3928 pass the format letter 's' down low enough that it can be seen
3929 to avoid this problem.
3930 (print_formatted): Pass format arg to value_print.
3931 (restore_addressprint): Remove function.
3932 (do_examine): Avoid hacking addressprint, cleanups and such.
3933 (print_frame_args): Add a comment to a Bothner change.
3934 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
3935 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
3936 to wipe out the values cached in blockframe.c.
3937 * symtab.c (find_method): Add comment saying how big you must
3938 allocate to be "big enough". Per being terse again.
3939 * valprint.c (val_print): Handle format letter "s" to print
3940 strings without addresses. Add comment to vtbl printing code
3941 which casts with wild abandon. Rearrange reference-printing
3943 @0xaddr: value (print w/addressprint)
3944 value (print w/~addressprint)
3945 @0xaddr (parameter lists w/addressprint)
3946 or nothing (parameter lists w/o addressprint)
3948 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
3950 * Merge more changes from Per Bothner:
3952 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
3953 annoying) that I tried to improve it. Here are my suggestions.
3955 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
3958 Do automatic de-reference when taking the address of a reference.
3960 Don't deref_ref when printing parameter lists.
3962 More attempts at treating refernences properly.
3964 In val_print, if deref_ref==0, don't print dangling " = ".
3966 Add COERCE_REF macro, which de-references an REF.
3968 * Merge changes from Per Bothner:
3970 * Fixed (Sony news)-specific configuration problems.
3971 * Fixed other problems with using vanilla pcc and libc (enum problems;
3972 assumption that vsprintf exists).
3973 * Some major speed-ups (finc_pc_partial_function now caches a match;
3974 parsing avoids duplicate symbol_lookup calls).
3975 * Changed handling of baseclasses (no longer use baseclasses field
3976 of struct type, use the first n_baseclasses fields instead).
3977 * Various minor changes/fixes, most C++-related.
3980 Cache the most previous match from find_pc_partial_function.
3981 (Save both low and high ends of matching function's pc range.)
3982 This speeds up the loop of infrun.c:wait_for_inferior quite
3983 a bit, and makes step/next commands much zippier.
3985 Added an enum->int cast (otherwise, some compilers barf).
3987 No longer set baseclass offset to 0, since multiple
3988 inheritance now mostly works.
3989 Added a number of casts, to shut up compiler warnings
3990 (after stabs where made enums, not ints).
3991 When discarding a symbol table (in symbol_file_command),
3992 must clear the cache introduced in blockframe.c.
3993 Don't convert $vtbl_ptr_type to vtbl any more.
3994 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
3995 Mask off sign bit emitted by g++ for virtual table offset.
3996 Set voffset to -1 (not 1) for static member functions.
3998 Changed parsing/lexing of names to avoid doing symbol lookup twice
3999 (once when lexing to determine symbol class, once for real).
4000 Now only call symbol_lookup once. Fields of 'this' win especially big.
4002 Subpress printing addr twice in the case of 'x/s addr'.
4004 lookup_basetype_type is no longer used.
4005 Add find_methods as recursive helper function to decode_line_1.
4006 This allows multiple inheritance to work.
4007 Also, once one or more matches has been found, do not look in
4008 base-classes. (Baseclass methods would be overridden, anyway.)
4010 Removed baseclasses array in struct type.
4011 Instead of using baseclasses[i], use fields[i-1].
4012 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
4013 Changed sign convention of voffset (previous was inconsistent).
4015 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4017 Used to assume existence of vsprintf. Re-written to not need it
4018 if HAVE_VPRINTF is undefined.
4020 typecmp was too pessimistic. Made it less so.
4022 Don't print space after address.
4023 If vtable points to a misc symbol (with 0 offset), print it,
4024 since that indicates the actual class of the object.
4025 Changed ype_print_derivation_info to use new inheritance
4026 scheme (without baseclasses vector).
4028 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4029 Also, changes needed because TYPE_BASECLASSES were removed.
4031 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4033 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4036 If there is no path set, and the symbols don't indicate what directory
4037 a file was compiled in, look in the current directory. But either
4038 a path or a known compilation directory will prevent this.
4041 Three independent bug fixes:
4042 * Remove the #if 0 block that breaks some stuff.
4043 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4044 adapt gdb to either SunOS 4.0.* or 4.1.
4045 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4048 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4051 (type_print) Demangle the name being printed.
4052 (type_print_base) Handle botched demangling without coredump (tiemann).
4055 (check_stub_method): Document routine.
4056 (tiemann) fix bug for no-arg functions
4057 Avoid clobbering beyond end of malloc'd storage.
4058 Terminate the argument list properly.
4060 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4062 * Changes merged by John Gilmore:
4065 In breakpoint_1, use new print_address_symbolic instead
4066 of find_pc_partial_function. (This forces use of assembler-level
4067 addresses, and avoids misleading non-mangled source-level names.)
4069 Generalize ansi argument such that -1 means skip arglist totally.
4070 Removed global variable print_ansi_qualifiers (which made
4071 code non-reentrant), in favor of extra explicit arguments
4072 to internal routines.
4074 Add new helper function print_address_symbolic.
4075 Use find_pc_misc_function instead of find_pc_partial_function
4076 (since we want assembler-level symbols here).
4078 Print unknown function as just "f (...)", not "f (...) (...)".
4079 Use new fputs_demangled explicitly.
4081 Fixed a typing violation (problem: value.h cannot be imported
4082 without renaming many variable in this file).
4083 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4084 decode_line_1: Moved forward some never-reached code.
4085 Made decode_line_2 skip function prologues correctly.
4087 fputs_filtered should not demangle by default.
4088 Add new fputs_demangled to demangle on demand..
4090 Change value_struct_elt to use value_primitive_field (using recursive
4091 utility function search_struct_field). This allows foo.bar to work
4092 for multiple inheritance (so far only for data fields).
4093 Change check_field in the same way (recursive helper function
4094 to support multiple inheritance).
4095 (Note: there are more of these problems that I haven't fixed.
4096 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4097 value_of_this: 'this' symbol name is now just "this", note "$this".
4099 Don't print static members.
4100 Avoid printing "members of <type>" if there are none.
4101 Simplified type_print_derivation_info by merging duplicate code.
4102 Remove useless blank lines in type_print_base (ptype command).
4104 Added declaration of new routine value_primitive_field.
4106 Added value_primitive_field which is generalized version of
4107 value_field that can handle multiple inheritance (non-zero offsets etc).
4108 Re-implemented value_field to call value_primitive_field.
4110 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
4112 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4113 delete the whole environment. Karl Berry reported the bug.
4114 * source.c - fix openp to avoid //'s in filenames, which
4115 trigger an Emacs bug causing it to not be able to find files
4116 when running gdb in a window.
4117 * dbxread.c - zap the #if 0 that botches the add-file code.
4118 It seems to work a lot better without all the code commented out.

4122 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
4125 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
4127 * Makefile - added a ${CFLAGS} to a couple of entries,
4128 added remote-sa.sparc.c
4129 * added remote.sa-sparc.c, a modification of remote.c
4130 which conducts a dialog directly with the SparcStation prom.
4131 * breakpoint.c, infrun.c, sparcdep.c added
4132 remote_insert_breakpoint(), and remote_remove_breakpoint()
4133 to breakpoint.c instead of directly writing breakpoint instructions.
4134 * sparcdep.c on remote_debugging,there is no need
4135 to remove signle step breakpoint instructions.
4136 * main.c added "-epoch" flag and "int epoch_interface" to main.c
4138 * printcmd.c - epoch interface sends lisp expressions to open up
4139 epoch windows on inspection.
4140 * valprint.c - added arrayprint, and addressprint and made adding
4141 format controls easier
4142 * wait.h added a couple of undef's because we were getting
4143 complaints about WSTOPSIG and WTERMSIG begin redefined.

4213 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
4214 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
4215 when printing the type.

4239 step_resume_break_address != NULL, even if another_trap.
4240 If trap_expected and we enter sigtramp, then set up a
4242 If trap_expected is set when we hit the step_resume_break,
