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

1000 * symfile.c: Rename add_syms_command to add_symbol_file_command.
1001 (_initialize_symfile, add_syms_addr_command):
1002 Rename add-syms to add-symbol-file.
1004 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
1006 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
1007 * symfile.c (clear_symtab_users_once, cashier_psymtab,
1008 free_named_symtabs): Move these routines from symmisc.c.
1009 * symmisc.c (same): same.
1010 (free_symtab): Make non-static.
1011 * symtab.h (free_symtab): Declare as exported void fn now.
1012 * dbxread.c (end_symtab, end_psymtab): Change comments.
1013 (initialize_dbxread): Call dbx_new_init() in case the first
1014 command is add-symbols.
1015 * target.c (dummy_target): Permit add_syms_addr_command.
1017 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1019 Permit symbols to be superseded when new symbol files have
1020 been read in, particularly for VxWorks.
1022 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
1023 to the main file, as well as to include files. Also, put global
1024 functions into the global psymtab, to make "i fun" work.
1025 (end_psymtab): Free named symtabs and psymtabs for a file, once a
1026 new psymtab for it has been read.
1027 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
1028 a file, once a new symtab has been read for it.
1029 * mipsread.c: FIXME. We need to do the same for MIPS, but it
1030 looks harder to determine the top-level block before it's been
1031 queued to the psymtab list.
1033 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
1034 If we have wiped out any old symbol tables, clean up at end of
1036 (symbol_file_command): Don't reference symfile_fns if it's zero.
1038 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
1039 defines for the blocks of a blockvector that contain global and
1040 file-static symbols and the first of the smaller scope contours.
1041 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
1042 decode_line_1, make_symbol_completion_list): Use the above.
1043 * coffread.c (end_symtab, patch_opaque_types): Ditto.
1044 * dbxread.c (end_symtab): Ditto.
1045 * expread.y (block): Ditto.
1046 * mipsread.c (throughout): Ditto.
1047 * symmisc.c (free_named_symtabs): Ditto.
1049 * symtab.c (list_symbols): Process the first symbol of the
1050 static psymbols list.
1051 (types_info): Restore this function from its untimely #if 0.
1052 It's not perfect, but it is better than nothing.
1053 (_initialize_symtab): Restore "info types".
1055 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1057 * m68k-stub.c: Remote stub for 680x0's, created from
1058 rem-m68k.shar (which is removed).
1059 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
1060 Remove RCS log stuff now that we use CVS and it blows our diffs.
1062 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1064 * symmisc.c (free_named_symtab): Make it work, in its current
1065 kludgy fashion. Change result to indicate if we blew away bkpts.
1066 * dbxread.c (end_symtab): Accumulate result from
1067 free_named_symtab and print warning if we blew user's state.
1068 * symfile.h: free_named_symtab now returns an int.
1070 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1072 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
1073 is the first symbol read, even if not mainline.
1074 (dbx_psymtab_to_symtab): symfile might be zero, cope.
1075 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1076 (set_section_command): New command ("section xxx yyy" -- should
1077 be renamed to "set section xxx yyy" FIXME) which sets the
1078 base address of a section of the exec file, overriding the
1079 virtual address that BFD reports.
1081 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1083 * exec.c: Add add_syms_addr_command to exec_ops, so you can
1084 load symbols at any address while examining an exec file.
1086 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1088 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1089 for printing the float info is host-dependent, not
1090 target-dependent. FIXME.
1091 * i386-pinsn.c: Move #includes to top, remove useless ones.
1092 * i386-tdep.c: Don't bother including <.../reg.h> since we
1093 don't use it (and it doesn't exist on host systems).
1095 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1096 Convert negative numbers properly.
1097 (ieee_test): Make numbers really random; fix format arg.
1099 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1100 * core.c (core_detach): Unpush core_ops, which might not be on
1101 top. We used to just pop the top, which broke things. Don't
1102 need dont_repeat() any more.
1103 (core_file_command): Psst! Don't repeat it.
1104 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1105 * expprint.c (print_subexp): Avoid switch fallthru on
1106 BINOP_ASSIGN_MODIFY, so we can print += and such.
1107 * frame.h: Fix typo.
1108 * inflow.c (kill_command): After killing inferior, print our
1109 current frame in the core file, if we have one.
1110 (generic_mourn_inferior): When inferior dies, either select
1111 the current frame (in the new target, e.g. core file), or
1112 set both the current and selected frames to NULL.
1114 Changes from Peter Schauer.
1116 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1118 * Make all file names fit in 14 characters (sigh and damn!):
1119 mv hp300hpux-xdep.c hp300ux-xdep.c
1120 mv symmetry-xdep.c symm-xdep.c
1121 mv symmetry-tdep.c symm-tdep.c
1122 mv convex-opcode.h convx-opcode.h
1123 mv tm-vxworks960.h tm-vx960.h
1124 mv tm-vxworks68.h tm-vx68.h
1125 mv Makefile.srcdir Makefile.sdir
1126 mv gdb-int.texinfo gdbint.texinfo
1127 mv remote-sa.m68k.shar rem-m68k.shar
1128 mv remote-multi.shar rem-multi.shar
1129 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1130 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1131 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1134 * command.c (user_info_1, user_info): New command for listing
1135 the user-defined commands.
1137 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1139 * dbxread.c (really_free_pendings): Clear file_symbols
1140 and global_symbols after freeing them; otherwise, running
1141 this function twice (if it appears twice on the cleanup
1142 chain), we try to free things twice.
1144 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1145 based on text_addr (the address of text in core), not on addr (the
1146 offset between text in the .o file and in core). This change
1147 is from Peter Schauer.
1149 * main.c: Define ALL_CLEANUPS as a cast of zero.
1150 (return_to_top_level): Use it.
1151 (main): Do all cleanups after each command run as part
1152 of the gdb startup sequence. Also do all cleanups before
1153 entering the command loop, and every time we exit the command
1154 loop and reenter. Before, the cleanups from the startup sequence
1155 were being left undone until the first error!
1156 (command_loop): Rename do_nothing cleanup to command_loop_marker
1157 so we can see it easily when examining the cleanup chain.
1158 (init_signals): Add another do_nothing for signal handling.
1159 (quit_command): Only try to kill target if it has execution.
1160 Problems in the target stack got us into a state where
1161 inferior_pid was nonzero but none of the targets had execution.
1162 In this state you couldn't exit gdb.
1164 * dbxread.c: Two changes from Peter Schauer.
1165 (echo_command): Fflush output after an echo command.
1166 (show_history): Pass all args to cmd_show_list.
1168 * utils.c (init_malloc): Call mtrace to turn on tracing
1169 if the environment variable MALLOC_TRACE is set to a file name.
1170 * mtrace.c: Add source file which provides a log of every malloc,
1171 free, and realloc to a trace file.
1172 * mtrace.awk: Add source file which analyzes the trace file.
1173 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1174 (VERSION): Roll to 3.94.3.
1176 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1177 (check_duplicates): Don't bother with watchpoints.
1178 (set_raw_breakpoint): Comment about danger of this routine.
1179 (watch_command): Parse and eval all args before calling
1182 * solib.c (find_solib): Avoid error in referencing memory to
1183 see if any more shared libraries have been added. This is
1184 particularly useful if the target has terminated. Bug reported
1187 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1188 in bringing up 3.94.2 on the Sun-3.
1190 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1191 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1192 expression (in scope) before reenabling watchpoint.
1193 * signame.c (init_sigs): Add missing declaration of i, fix
1194 sys_siglist declaration.
1195 * source.c (list_command): Fixed range computation to use
1197 * stack.c (backtrace_command): Do not allow command if target has
1198 no stack, print informative error message.
1199 * target.c (target_command): Do not write into command line
1200 because this fails if the target command is used in a user defined
1201 command. [This change was enhanced by gnu to support any-
1202 unique-prefix matching on target names.]
1203 * valops.c (value_struct_elt): Avoid infinite loop on an
1204 erroneous attempt to print the member of function (try p main.p).
1206 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1208 * expread.y (name_no_typename): Avoid reduce/reduce errors
1209 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1210 Since the GDB parser really doesn't use name_no_typename in a
1211 name-only context, the parser can't tell the diff between
1212 names and numbers here. Avoid allowing a name_no_typename
1213 to be a NAME_OR_*INT to resolve the conflict.
1215 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1217 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1219 * valprint.c (val_print_fields): bitfield printing didn't handle
1220 byte order. Indirect through a few more fns to cope.
1222 * values.c (modify_field): also cope with byte order.
1224 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1226 Cleanup for release 3.94.2:
1228 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1229 include files. Roll version to 3.94.2.
1231 * coffread.c (init_stringtab): Read length into unsigned char
1232 array before swapping; don't assume 32-bit longs.
1234 * target.c (target_info): Don't bother with get_sym_file, just use
1235 the symfile global variable.
1236 * symtab.h, symfile.c (get_sym_file): Delete it.
1238 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1239 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1240 (read_type): Replace one more error() with complain().
1242 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1244 * i960-tdep.c: Fix copyright attribution.
1246 * config.gdb: Quote all backquotes in doublequotes. You can
1247 quote me on that. BSD 4.4 shell found this one.
1249 * infptrace.c (throughout): The third argument to ptrace is an
1252 * infrun.c (wait_for_inferior): When program has terminated, we
1253 have to call target_terminal_ours before we pop that target off
1254 the stack (e.g. before a call to target_kill or
1255 target_mourn_inferior). This fixes problem where a program
1256 terminates, then GDB stops for (tty output) and you have to type
1257 "fg" to the shell to resume it. FIXME: This code for what to
1258 do after termination really should be in normal_stop instead.
1260 * gdbcore.h (read_memory_check): Change declaration; it changed
1263 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1264 4.4 prereleases, this avoids a bug in their sgtty compatability
1266 * remote.c: Use terminal.h rather than hand-rolling the same.
1268 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1269 * utils.c (strsave, strstr): Fix arg types.
1270 * valprint.c (val_print): lint
1272 MIPS symbol table support from Per Bothner:
1274 * symfile.c (symtab_fns): Remove initializer table that needs to
1275 be hacked for each new symbol file format supported.
1276 (add_symtab_fns): New function, chains symbol table
1277 handlers into the global list.
1278 (symfile_init): Search this list.
1279 * symfile.h: Add next pointer, declare add_symtab_fns.
1280 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1281 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1283 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1284 symbol *). Thus, we no longer need the hack to trash
1285 pst->filename. Good, since that hack confused code in symfile.c!
1287 (reorder_symtabs, destroy_all_symtabs): Removed static
1288 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1289 Instead, the latter now uses a temporary array (stack-allocated
1290 from an obstack, and then freed).
1292 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1293 haven't been set in the outermost stBlock of a procedure. This was
1294 a problem with f77 binaries on Ultrix 4.?.
1296 (new_symtab, new_symbol, new_type): Continue changing code to use
1297 obstacks more and otherwise conform to dbxread internal style.
1298 Made the free_code of symtabs be free_linetable (as in dbxread)
1299 instead of free_contents. This implies memory leaks when reading
1300 a new symbol table, until the conversion is finished. Did change
1301 (struct symbol) and (struct type) to be allocated on the
1302 symbol_obstack. Blocks and blockvectors are among the things
1305 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1306 tested much, but it solved one problem (reported by Meissner), and
1307 cleans up some other things. The problem happened when an
1308 included file contains actual code (functions) and not just
1309 definitions. The mips coff is a little inconvenient there, since
1310 it may cause a procedure to be mapped to the wrong psymtab.
1312 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1313 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1314 this will need work for the new core paradigm.
1316 Opcode patches from the net:
1318 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1319 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1320 missing altogether - they are added here. From Bruce Bauman.
1321 * mips-opcode.h: The low mask for C0 instructions was too small.
1322 From Garrett Lau. I modified the fix to check the entire 32-bit
1325 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1328 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1330 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1332 * dbxread.c (read_type): Pointer subtraction (value_sub in
1333 valarith.c) sometimes failed because the types of the
1334 pointers being subtracted were not identical.
1335 These differed because dbxread.c was allocating pointer types
1336 using dbx_alloc_type+smash_to_pointer_type instead of
1337 lookup_pointer_type. I failed to find a justification for the
1338 former, so I changed it to use the latter. Similarly, I
1339 replaced smash_to_function_type by lookup_function_type,
1340 and smash_to_reference_type by lookup_reference_type.
1342 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1343 _initialize_mipsread): corresponding changes.
1345 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1347 * source.c (mod_path): Do tilde_expand on each component of the path,
1348 rather than on the (list of) paths as a whole.
1349 (print_source_lines): Set first_line_listed in addition to
1350 current_source_symtab and current_source_line. If the source was
1351 not findable, after a "dir" command to fix the problem,
1352 a "list" would get the wrong lines.
1354 While I was there... (gnu):
1356 * dbxread.c (read_type): Change error to complaint.
1358 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1360 First attempt at detailed understanding of symbol table memory alloc.
1362 * dbxread.c (dbx_symfile_read): Free our string table if we
1363 aren't the mainline. Free the "info" struct since we're done with
1365 (init_psymbol_list): Free any previously allocated psymbol lists.
1366 (): FIXME: Should realloc-down the psymbol lists when done reading
1367 the main symbol file?
1369 * symmisc.c (free_symtab): Free fullname field too.
1371 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1372 (REGISTER_ADDR): Make result type unsigned int.
1374 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1375 define REGEX must also define REGEX1 (its dependency).
1377 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1379 * tconfig/i960: No longer works, points you at vxworks960 or
1382 * xgdb.c, XGDB-README: Remove file. Users can get the much
1384 * Makefile.dist: Remove all trace of xgdb.
1386 * breakpoint.c (breakpoint_1): Pass demangle arg to
1387 print_address_symbolic.
1388 (clear_breakpoints): Remove unused function.
1389 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1390 (breakpoint_re_set): Use catch_errors to do them all anyway.
1392 * gdb-int.texinfo (Host versus Target): Add section on what is
1393 a "host" feature versus what is a "target" feature.
1395 * infcmd.c (path_command, path_info): Handle the PATH variable
1396 (object search path) as conveniently as the source search path.
1397 * environ.c (set_in_environ): Set some vars in GDB's environment,
1398 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1399 * source.c (mod_path): New function, from guts of
1400 directory_command, modifies a path. Used by path_command.
1401 (directory_command): Call it.
1402 * defs.h (strsave): Declare.
1404 * utils.c (sevenbit_strings): Add new printing option.
1405 (printchar): Use it.
1406 (strsave): Provide this handy helper routine.
1407 (set_width_command): Rename set_screen_width_command.
1408 (_initialize_utils): "set screen-width" => "set width";
1409 "set screen-height" => "set height"; add sevenbit-strings.
1411 * infcmd.c (do_registers_info): Print floating point registers
1412 in raw hex as well as float format, regardless of whether it is
1413 a "virtual" convertible register.
1414 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1415 regs as a double, just in case it's being used that way.
1416 * values.c (unpack_long): Comment on array/function coercion.
1417 (unpack_double): Argument is in target byte order now. For
1418 integer arguments, just call unpack_long and float the result.
1419 * m68k-tdep.c: include defs.h for "const" handling.
1420 * remote-nindy.c: Use ieee-float stuff.
1421 (nindy_fetch_registers): Unpack double regs to host double, then
1423 (nindy_store_registers): Pack extendeds to host double, flip
1424 around by misusing unpack_double, send as target double.
1426 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1427 zero, as when stopped at the first instruction of a process.
1429 * blockframe.c: Fix filename in comment (param.h => tm.h).
1430 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1431 * tm-68k.h: Fix typos.
1433 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1435 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1437 * coredep.c (fetch_core_registers): Pass end-address of register
1438 section to register_addr as expected. Don't call supply_register
1439 if we'd just pass it garbage.
1441 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1443 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1445 * target.c (push_target, target_info): Cast enums to int for < or
1448 * stack.c (print_frame_info): Identify source file & line
1449 even if we can't print it.
1451 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1453 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1455 Clean up IEEE floating point support.
1457 * ieee-float.h: New file.
1458 * ieee-float.c: Write real routines to convert between host
1459 doubles and various target IEEE extendeds.
1460 * m68k-xdep.c: Eliminate assembler code for extended floats.
1461 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1462 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1463 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1464 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1465 double_to_ieee_extended.
1466 * i960-tdep.c: Define ext_format_i960.
1467 * m68k-tdep.c: Define ext_format_68881.
1468 * sparc-tdep.c: Define ext_format_sparc, though unused.
1469 * Makefile.dist (HFILES): Add ieee-float.h.
1470 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1473 Obsolete the "coffstrip" program in favor of using BFD's strip.
1475 * nindy-share/coffstrip.c: Remove file.
1476 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1477 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1478 * tconfig/nindy960: Remove reference to coffstrip.o.
1480 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1482 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1484 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1485 * dbxread.c: Remove static symfile_bfd.
1486 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1488 * inftarg.c (child_detach): Pop the child_ops vector if the
1489 detach is successful.
1490 * remote-nindy.c (nindy_create_inferior): Don't push a new
1491 nindy_ops since nindy uses the same one for execution and memory
1493 * core.c (core_ops): Use child_attach and child_create_inferior
1494 rather than default attach and create_inferior functions.
1496 Handle floating point registers in core files.
1498 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1499 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1500 This version untested since BFD doesn't yet support sun3 core
1502 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1503 conventions. Fix comments and style. This version has not
1504 been compiled yet, since we have no HP inhouse.
1505 * core.c (get_core_registers): Look for two sections, ".reg"
1506 and ".reg2", and pass both to fetch_core_registers sequentially.
1508 Revise directory path yet again.
1510 * source.c (forget_cached_source_info): Not static any more.
1511 (init_source_path): New default source path is "$cdir:$cwd".
1512 (dir_command): Handle variable arguments ($cdir, $cwd).
1513 (source_info): Print "Compilation directory" rather than
1514 "Originally compiled in" to remind people of $cdir.
1515 (openp): If the path contains $cwd, use current directory.
1516 (open_source_file): If compilation directory is known, replace
1517 first $cdir in path with the compilation directory.
1518 (print_source_lines): Even if we can't print the lines, set the
1519 current symtab and line for future commands like "info source" or
1520 "breakpoint". Also, error message now contains the file name,
1521 line number, and file access error message.
1522 (_initialize_source): Fix help text to describe changes.
1523 * main.c (cd_command): Forget cached source info when we chdir.
1524 * utils.c (strstr): Add simple implementation.
1526 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1528 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1529 Byte-swap COFF symbol tables if necessary when reading them in.
1530 Use complain() to replace error message in one spot. Needs
1531 corresponding change in bfd/coff-code.h to make some symbol
1532 swapping routines non-static.
1534 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1536 Merge changes from Eirik Fuller, for UTek.
1538 * defs.h (errno): Add declaration.
1539 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
1540 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1541 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1542 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
1543 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
1544 declarations of errno.
1546 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1548 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1549 <rpc/rpc.h> and <rpc/types.h>.
1551 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1553 * i960-tdep.c (examine_prologue): Add new argument limit,
1554 which stops the scan at the end of the prologue, or at the PC.
1555 This fixes a problem where it walks down into the code for the
1556 user's statements if that code looks like function prologues.
1557 Mark Fox and I have been bouncing this code back and forth, making
1558 small changes to it. Callers changed to match.
1560 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1562 Cleanup for gdb-3.94 release final:
1564 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1565 the .c files from vx-share and nindy-share, from the various
1566 macros, since they are not found via ALLDEPFILES.
1567 (SFILES): Add tm-i960.h.
1568 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1569 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1571 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1572 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
1574 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
1576 * am29k-tdep.c: Add contribution line.
1577 (examine_prologue): Cache information about function prologues in
1578 the misc-function-vector to avoid lots of references over the
1579 serial line while examining instructions.
1581 * core.c (core_close): New function made from cleanup_core.
1583 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1584 remote-vx.c, remote.c, target.c, target.h,
1585 Update target_ops vector to add attach, close, and load entries.
1586 Use add_syms_addr_command, not add_file_addr_command, for
1587 add_file. Break out close routine from existing code.
1589 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1590 they are in an obstack.
1591 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1593 (define_symbol): Add symbol type parameter; change callers;
1594 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1595 it to influence the symbol class on the i960.
1596 (define_symbol): Swap LOC_CONST's into target byte order.
1598 * exec.c (exec_close): New function.
1599 (exec_file_command): Call it.
1601 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1602 Fix byte order of frame pointer.
1603 (read_var_value): Result of 0 if var's value can't be found,
1604 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1605 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1606 (locate_var_value): Use read_var_value and use its lazy address
1607 as the location of the var's value. Lint.
1609 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1612 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1613 obsolete Intel versions in favor of vxgdb versions.
1614 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1615 code dealing with byte order of values, which Intel did in host byte
1616 order rather than gdb-4's target byte order.
1617 (i960_frame_chain_valid): Move to nindy-tdep.c.
1618 (examine_prologue, skip_prologue, frame_find_saved_regs,
1619 frame_args_address, leafproc_return, saved_pc_after_call,
1620 pop_frame): Add vxgdb versions from Mark Fox.
1621 (examine_prologue, frame_struct_result_address): Add code
1622 to deal with the saved value of G13 (struct return address
1624 (frame_args_address): Modify Mark's version to prefer the
1625 saved value over the current value in the topmost frame.
1626 Cache result in the frame info to avoid performance hair in
1628 (print_fault): Add gdb960 code for printing faults.
1629 (_initialize_i960): Actually call check_host.
1631 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1632 add stub routines. FIXME, these currently just return zero!
1634 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1635 (attach_command): Call target_attach, not target_open, now.
1637 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1638 (child_attach): Rename from child_open.
1639 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1640 don't confuse it with a zero step_resume_break_address.
1642 * inftarg.c (child_detach): Eliminate inferior_pid test.
1643 (child_files_info): Clean up message a bit.
1644 (child_ops): Use child_attach, not child_open, to attach.
1646 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1647 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1648 findvar.c to here, since it depends on the contents of the
1649 shadow_contents of breakpoints, but keep if #if 0 since it is
1652 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1655 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1656 (ptype_command, display_command): Eliminate have_inferior_p and
1657 have_core_file_p in favor of target_has_stack or
1658 target_has_execution.
1659 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1660 code for actually finding the values of arguments, though we still
1661 keep track of the maximum stack offset for use in printing unnamed
1662 arguments. Handle missing FRAME_ARGS_ADDRESS.
1664 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1665 (struct nindy_regs): Define registers passed to/from nindy.
1666 (nindy_fetch_registers, nindy_store-registers): Translate between
1667 nindy and GDB formats for the registers.
1668 (dcache_init): Statically allocate the cache, since it was being
1669 allocated by a malloc that was never freed anyway.
1670 (nindy_create_inferior): Error, not core dump, if no exec file.
1671 (nindy_before_main_loop): Use target_load, not target_add_file.
1673 * remote-vx.c (net_load): Specify large timeout for load
1674 requests. Allow user to break out with INTERRUPT.
1675 (net_break): Remove useless code, clean up. Change callers.
1676 (parse-args, skip_white_space, find_white_space): Clean up arg
1677 parsing to cope with quoted strings.
1678 (net_wait, net_quit): Never call error, just return status.
1679 (vx_read_register, vx_write_register): Cleanup status checking.
1680 #ifdef the code based on which CPU we are using (960 or 68k),
1681 FIXME, this should be completely general but it isn't yet.
1682 (vx_xfer_memory, vx_resume): Cleanup status checking.
1683 (vx_run_files_info): Improve message.
1684 (vx_load_command): Renamed from vx_add_file_command. Allow load
1686 (net_ptrace): Remove unused routine.
1687 (vx_wait): Adopt code from vxgdb960 to cope with broken
1688 connections to target machine and prompt to disconnect. Remove
1689 debug printouts. Map some EVENT_'s to SIGnals.
1690 (add_symbol_stub, vx_open): Print names of object files we found,
1691 and "ok" if we read their symbols OK. Clarify output in general.
1692 (vx_attach, vx_detach, vx_kill): Add these commands.
1693 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1694 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1695 "info files" output, and create_inferior, since we already have
1698 * stack.c (frame_info): Replace Frame_unknown with 0.
1699 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1700 (return_command): Pop until the PC matches as well as the FP,
1701 so it works even if the FP is shared with another function,
1702 as in "frameless" or "leaf" procedures.
1704 * symfile.c (load_command): renamed from add_file_target_command.
1705 (add_syms_addr_command): renamed from add_file_addr_command.
1706 (add_syms_command): Stub to call target_add_syms.
1707 (_initialize_symfile): Change command names and descriptions,
1708 add-file => add-syms, and load from alias to its own command.
1710 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1711 maybe_kill_then_create_inferior): Default for attempts to start
1712 a process, if one is already running, is to ask about killing
1713 it and retry if yes.
1714 (upstack_create_inferior): #if-0 it, strata obsolete it.
1715 (push_target, unpush_target, pop_target): to_close() a target
1716 before unstacking it.
1717 (target_info): Renamed from target_files_info.
1718 (_initialize_targets): Rename "i files" as "i target", accessible
1721 * target.h: Improve comments about the target_ vectored routines.
1723 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
1724 Convert commenting style to standard GNU style.
1725 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
1726 (SKIP_PROLOGUE): No longer a no-op.
1727 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1728 (*_REGNUM): Sort register numbers.
1729 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1730 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1731 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1732 are now 10 byte extendeds, not 8 byte doubles.
1733 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1734 for nindy versus vxworks targets. FIXME, this should possibly go
1735 in the target vector.
1736 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1737 frame_saved_regs and arg pointer with each frame.
1738 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1739 (FRAME_ARGS_ADDRESS): Use cached result.
1740 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1741 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1742 (PRINT_RAMDON_SIGNAL): Call print_fault.
1743 (POP_FRAME): Now works.
1745 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1746 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1747 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1748 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1751 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1752 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1754 * valarith.c (value_subscripted_rvalue): Avoid handling
1755 floats and doubles specially; it gave alignment errors. Lint.
1757 * valops.c (value_of_variable, value_of_this): Error if unknown
1760 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1761 to avoid alignment problems.
1762 (value_print): Handle unknown value address.
1763 (cplus_val_print): Two args are ignored; remove them. Change caller.
1764 (val_print): Use unpack_long rather than pointer-deref.
1767 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1768 to avoid alignment problems.
1769 (value_being_returned): Error if return value unknown.
1770 (set_return_value): Add bogosity warning, FIXME. *
1772 * TODO: A woman's work is never done.
1774 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1775 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1776 Add ieee-float.o to OBS.
1777 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1778 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1779 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1781 Changes to generalize the VxWorks RPC protocol slightly, to handle
1782 i960 as well as 68000.
1784 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1785 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1786 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1787 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1788 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1789 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1790 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1791 so they will move in target byte order rather than network
1792 byte order (happens to be the same).
1794 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1796 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1798 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1801 Add contribution lines to various files, showing where they
1804 * breakpoint.c (break_insn, check_break_insn_size,
1805 read_memory_nobpt): Remove to mem-break.c.
1807 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1810 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1811 entry has bad register number. This change is not
1812 tested in this release, FIXME.
1814 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1817 * value.h: Force value's contents field to be aligned to hold
1818 at least a double or a long long (if supported). This avoids
1819 doing bcopy's in and out of the contents field.
1821 (step_1): Avoid coredump under obscure circumstances when we
1824 * symtab.h (misc_info): Add field to misc function vector for
1825 any kind of cached information the target code desires. AMD
1826 29000 uses this to avoid repeating examine_function_prologue's.
1828 * coffread.c: Lint. Remove static symfile, read_section_header.
1829 core.c (have_core_file_p): Lint: remove.
1830 expprint.c (print_subexp): Lint.
1831 infptrace.c, valops.c, valprint.c: lint.
1833 Roll in changes from vxgdb-5.0.1:
1835 * symtab.h: Comment byte order of each address class. Add
1836 LOC_LOCAL_ARG for frame-relative args (960).
1837 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1838 symtab.c, symmisc.c: ditto.
1840 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1842 * remote.c (remote_resume): Error if resume with a signal.
1844 * symfile.c (prim_record_misc_function): Clear misc_info.
1845 (fill_in_vptr_fieldno): Check stub type of arg.
1847 * valops.c (value_cast): Avoid looking up names of types whose
1848 name we don't know, to prevent coredump. Sun CC produces typedef
1849 rtx and the name of *rtx is zero...
1851 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1853 Roll in changes from final AMD 29000 port (Tiemann).
1855 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
1856 for ../include/a.out.encap.h. This might not work now that BFD
1857 is separately compiled. Instead, BFD support for encap will have
1858 to translate machine type 29k into the right COFF_MAGIC.
1860 * infcmd.c: Remove references to inferior_pid that aren't used
1861 in actual ptrace calls; use target_has_execution, etc.
1862 (have_inferior_p): Remove function.
1863 (program_info): Print target info rather than "process number";
1864 avoid gratuitous messages unless from_tty.
1865 (run_stack_dummy, finish_command): Set proceed_to_finish.
1866 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
1867 main.c: Lint. Lose have_inferior_p().
1868 inferior.h (have_inferior_p): Remove, lint.
1869 (proceed_to_finish): Add flag to ask that all regs be saved
1870 by normal_stop, for the few commands that need it, speeding up
1871 serial I/O. Add comments to stop_registers.
1873 * remote-eb.c: Remove newline from breakpoint message we grep
1874 for. Never time out when running the user program.
1878 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1880 Roll in changes from vxgdb-5.0.1:
1882 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
1883 symbol in its raw form, we are processing an unlinked ".o" file.
1884 See if the target environment has assigned it an address, using
1885 target_lookup_symbol (VxWorks does), and enter it into the symtab
1888 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
1889 68k versions for a simpler version that assumes zero FP at bottom.
1890 Fixes bug of truncated stack reports.
1892 * target.h (target_lookup_symbol): Define this routine's args
1893 and result, finally.
1895 * target.c (nosymbol): Default routine for target_lookup_symbol.
1896 (target_default): Default lookup_symbol and call_function too.
1897 (files_info): Only print has_all_memory warning if a non-dummy
1900 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
1901 vx_convert_from_virtual): If target does not have floating point,
1902 zero register "values", and avoid doing cross-net conversions.
1903 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
1904 (vx_open): Rearrange code that attaches to target and reads
1905 symbols for all loaded modules, to work if some of the modules
1906 are not accessible. Add symbol_stub() and add_symbol_stub()
1907 as callbacks from catch_errors(). Allow connect attempt to be
1908 interrupted painlessly with ^C (FIXME, there are still some bugs
1909 if the interrupt happens during symbol reading.). Print
1910 final message with puts_filtered, since symbol messages are
1915 * main.c (catch_errors): Only print errstring if non-null.
1916 (command_loop): Avoid an ioctl per command to test ISATTY.
1918 * remote-vx.c (net_load): make static; avoid sophomoric msg.
1919 (vx_xfer_memory): Return correct result!
1920 (vx_files_info): Indicate whether target has float or not.
1921 (vx_lookup_symbol): Complain, not error, if target gone.
1922 (vx_open): Print "Connected" msg before disabling immediate-quit.
1923 [FIXME: lookup_symbol and vx_open changes need testing.]
1925 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
1926 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
1927 contributor lines and update copyrights to 1991.
1929 Changes from an attempted H-PUX host port:
1931 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
1932 defines PT_ATTACH and PT_DETACH but not PT_KILL.
1933 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
1934 * remote-vx.c: include <sys/time.h> for HPUX.
1935 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
1936 "core_file_command" routine to BFD regime. May not work yet.
1938 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
1940 * xgdb.c: Replace X10 version with some VJ version.
1941 (FIXME: Its copyright assignment is not on record.)
1942 * xgdb.c: Update include files to X11R4 (Xaw crud).
1943 (xgdb_display_source, create_text_widget): fix call to
1944 get_filename_and_charpos. Rewack source window stuff for X11R4
1945 (gleaned from include files, and "nm's" of binary libraries, since
1946 I had no doc available).
1947 (append_selection, append_selection_word): Disable with FIXME
1948 since R4 changed interface here.
1949 (create_buttons): Add back the old set of buttons.
1950 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
1952 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
1953 Roll VERSION to 3.94 (not yet final though).
1955 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1957 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
1958 obstack_int_grow, obstack_int_grow_fast): Eliminate
1959 cast on left of assignment, which gives MIPS cc fits and is
1962 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
1963 F_ALIAS. Use printf, not fprintf, when not passing a file
1965 (compare_opcodes): Check that identical instructions have
1966 identical opcodes, complain otherwise.
1968 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
1969 was reported by Roland McGrath.
1970 (unimp): Only match if exactly zero instruction. (Roland)
1971 (branches and traps): Generate all variations of these
1972 instructions with macros, based on a single call that defines
1973 each condition name and its binary representation.
1974 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
1976 * valprint.c (val_print_fields): Take, and use, format parameter.
1977 This means that "p/x struct" again prints the elements in the
1978 desired format. Changed callers.
1980 * stack.c (frame_info): Use filtered output, and indicate wrap
1981 points. Remove kludgy formatting designed to avoid line wrap.
1983 * utils.c (wrap_here): If the line is already full (because
1984 we had printed a long indent or long wrapped string), do an
1985 immediate newline-and-indent.
1987 * m68k-pinsn.c (print_insn_arg): Bugfix from
1988 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
1989 instruction is incorrectly disassembled as bkpt #8.
1991 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
1992 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
1993 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
1994 and then will dump core (sometimes). I traced it back to an
1995 uninitialized symfile_name in psymtab_to_symtab.
1996 (const_vol_complaint): Add quotes to message.
1997 (define_symbol): Only believe line number if gcc_compiled.
1998 Avoid allocating symbol if we will not return it.
2000 Add target strata support so that newly established targets go
2001 into their right place in the target stack (e.g. a new exec file
2002 doesn't wipe out the ability to access the running process).
2004 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2005 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2006 and initialize it properly in all the targets.
2008 * target.h: Document strata. Change return type of push_target.
2010 * target.c (nomemory): new function for dummy memory access.
2011 (tcomplain): Rename complain, now also used in symfile.c.
2012 (push_target): Push targets within strata. New return value shows
2013 whether new target is on top of stack or not. Always keep dummy
2015 (target_files_info): Ignore dummy target.
2017 * core.c (core_open): Warn user, and skip accessing file, if the
2018 core target is not the topmost target in the stack.
2019 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2022 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2023 target_ops, it doesn't belong there since we have no regs there.
2024 Change name of target from machine => memory to clarify.
2026 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2028 * Freeze version 3.93 for release.
2030 * Makefile.dist: Handle vx-share and nindy-share subdirs
2031 properly when building gdb.tar.Z.
2033 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2034 printed in various places, so I could change just one copy.
2036 * dbxread.c, coffread.c: Change references to bfd->iostream
2037 to cast to FILE *, now that BFD avoids needing types defined
2038 in other header files.
2040 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2042 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2043 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2044 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2045 (actually gcc -Wall).
2047 * dbxread.c: Remove first_global_sym, last_global_sym, since
2048 they are never referenced.
2050 * defs.h (baud_rate): Declare.
2051 main.c: Define it, and add the -b option to set it.
2053 * gdb-int.texinfo: Add text on how to define a new host or target
2054 architecture, prompted by Per Bothner's questions about MIPS
2057 * gdb.texinfo: Document "complaints". Change doc of -q since
2058 gdb no longer prints the copyright and blurb if you specify a file
2059 name to be debugged (just like Emacs). Add doc for Nindy-specific
2060 command line flags for specifying target serial port and such.
2061 Update copyright to 1991.
2063 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2064 has taken over for us the job of ripping up executable files. The
2065 crud caused Per Bothner's port to not compile.
2067 * infrun.c (normal_stop): Avoid printing "Program exited
2068 normally" if we are in batch mode. This allows a GDB which
2069 executes a program on a target system, to behave like a Unix
2070 command (input from stdin, output to stdout, no extraneous
2073 * main.c (main): Allow additional machine-dependent command line
2074 options to be specified with the ADDITIONAL_OPTIONS,
2075 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2076 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2077 processing to occur just before the main loop with
2078 BEFORE_MAIN_LOOP_HOOK.
2079 (main): If a "core file" argument is specified, and it is not a
2080 core file, try it as a process ID to attach.
2081 (symbol_completion_function): Attempt to cope with
2082 "show screen-" TAB, not very successfully. This needs more work,
2084 (batch_file): New function, returns whether we are reading
2085 commands from an interactive tty on stdin, or from somewhere else.
2086 Called by normal_stop since it doesn't get from_tty passed down
2087 to it like many commands do.
2089 * remote-nindy.c: Handle command line options for nindy
2091 (nindy_before_main_loop): Prompt user for tty name if they
2092 don't specify it before getting to the interactive command loop.
2094 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2095 and -r command line options. Also add hook before main loop
2096 to make it easy to specify a tty.
2098 * TODO: More things to do, one done.
2100 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2102 * dbxread.c: Make complaint() calls pass pointer, not struct.
2103 Add complaints about badly formatted C++ type information
2104 (const/volatile indicator, and parse errors resulting in
2105 error_type). Fix C++ virtual member fn comment.
2106 (read_struct_type): Avoid bumping pointer if we got a parse
2107 error; this prevents our walking beyond the end of a string.
2108 Terminate loop on null char as well as semicolon.
2109 (process_one_symbol): Fix the LBRAC fix so that it uses the
2110 last previous SLINE, FUN, or SO record's PC address. C++ debug
2111 symbols did not have SLINE records in a useful order compared
2112 to the LBRAC records.
2113 (define_symbol): Handle "catch" records.
2115 * symtab.c (check_stub_type): Added new complain
2116 `stub_noname_complain' and added a consistency check to
2117 keep the debugger from crashing when finishing from an
2118 exception frame. A real fix will be needed later.
2120 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2122 * infcmd.c (attach_command): Make global.
2124 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2125 but make them easy to comment out. Perhaps later they should
2126 be enabled by what CPU you configure for? FIXME.
2127 (VERSION): Roll to 3.93.
2128 (pinsn.o): Remove rule for obsolete file.
2129 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2131 Run down a problem that manifested by printing the wrong function
2132 name in stack traces of read_ofile_symtab. Turned out that the
2133 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2134 the LBRAC symbol with an address in the *data* segment, which
2135 blew our binary search through the blocks.
2137 * dbxread.c: Use the complain() facility consistently to bitch
2138 about problems in the symbol file we are reading.
2139 (finish_block): Add code to check the nesting of the blocks;
2140 complain and Procrust them to fit if wrong.
2141 (make_blockvector): Check the order of the blocks, complain
2142 [but don't cope] if wrong.
2143 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2144 symbols to be sure their PC value is greater than the last SLINE
2145 (line number) symbol we've seen, complaining and adopting the
2146 SLINE PC value if wrong.
2148 * symfile.h (struct complaint, complaint_root, complain,
2149 clear_complaints): Add.
2150 * symfile.c (complain, complaint_root, clear_complaints): Add
2151 facility to deal with non-fatal complaints and to regularize their
2153 (symbol_file_add): Clear complaint counters to allow new complaints.
2154 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2156 * dbxread.c (dbx_symfile_read): Remember the address and size
2157 of the string table for the main symbol file, so we won't read it
2159 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2160 to avoid reading the string table yet again. Lint.
2161 (throughout): Improve filtered output, including word wrap.
2162 (read_range_type): Improve Bothner's fix to handle other types too.
2164 * utils.c: Improve line wrap implementation. Handle unlimited
2165 width by making chars_per_line unsigned.
2166 (puts_filtered): New, easy, function.
2168 * defs.h (puts_filtered): add.
2170 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2171 call the identical sort_symtab_syms() in symfile.c instead.
2173 * expread.y: Suggest the `file' command rather than `symbol-file'.
2175 * command.h (enum var_types): Add zinteger for seroable
2177 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2178 nested if's into a switch.
2180 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2181 we did not stop because of a breakpoint (it must have been for
2182 some other reason, like a "stepi"), so don't print anything.
2184 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2185 doesn't include <sys/types.h>, old SunOS's require it for
2188 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2190 A test port of gdb-3.92.6 to the Sony NEWS.
2193 Don't normally link in remote- or vx stuff.
2194 Some of it doesn't compile, and it wastes space for 99% of the users.
2195 Remove reference to no-longer-used HAVE_VPRINTF.
2196 Fixed BFD_DEP typo to BFD_DIR.
2198 Fix cast in arg to bfd_h_getlong.
2199 Make char *prefix be const.
2200 Fix how certain range types are mapped into builtin unsigned int types.
2202 Remove 2 #includes. They cause errors (on Sony, at least),
2203 and aren't needed (they wern't in earlier versions).
2205 print_address_symbolic should never demangle labels
2206 (since it prints *assembler-level* labels).
2208 [This was superseded by the change to printcmd below.]
2211 Add some "volatile" return types to avoid warnings.
2212 If MISSING_VPRINTF add vprintf function and not just macro
2213 (since vprintf is used in printcmd.c).
2215 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2216 (The latter isn't grokked by some PCC-based compilers.)
2218 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2220 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2221 * nindy-share/coffstrip.c
2222 Added some forward declarations (otherwise, gcc complains
2223 about implicit extern redefined as static).
2225 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2227 Changes inspired by Per Bothner:
2228 * printcmd.c (print_address_symbolic): Take additional parameter
2229 specifying whether to demangle.
2230 (print_address): Pass in asm_demangle to control demangling.
2231 (print_address_demangle): New fn, takes explicit arg to control
2233 * utils.c: Add new vars demangle and asm_demangle, and let them
2235 (fputs_demangled): If !demangle, just print the argument.
2236 (fprint_symbol): If !demangle, just print raw symbol.
2237 * valprint.c (val_print): Call print_address_demangle rather than
2238 print_address, to cause demangling to depend on the global
2239 rather than assembler-level demangling setting.
2240 * WHATS.NEW, gdb.texinfo: Document.
2242 * main.c (show_command): Show all settings if no arg.
2243 (initialize_main): Make "info set" the same as naked "show".
2244 * command.c (cmd_show_list): Handle prefix commands in the
2245 list, and print the name of the setting as well as its English
2246 description and value.
2248 Allow gdb functions to specify where a line should wrap if it
2249 exceeds the size of a terminal line. Use it to make the output
2251 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2252 of the right size when screen width changes.
2253 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2254 (wrap_here): New fn, indicates a point in the output where we
2255 should wrap the line rather than just letting it overflow at a
2257 (fputs_filtered): Implement wrapping.
2258 (n_spaces): New fn, returns a pointer to N spaces.
2259 (print_spaces_filtered): Use n_spaces.
2260 * defs.h (n_spaces): Declare.
2261 * stack.c (print_frame_info): Wrap with 4-space indent after
2262 fn name and before filename and line number.
2263 * printcmd.c (print_frame_args): Wrap with 4-space indent
2264 before each argument name is printed.
2265 * valprint.c (value_print): Wrap with no indentation before
2267 (val_print_fields): Wrap with indentation relative to nesting
2268 level before each field name.
2269 (val_print): Wrap with nesting indentation before array elements.
2270 * command.c (do_setshow_command): Avoid extra newlines,
2271 wrap with 4-space indent around values printed, end with period.
2272 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2274 * breakpoint.c (breakpoint_1): Implement addressprint for
2275 "info breakpoints" display. Change file name and line number
2276 format to " at file:nnn" rather than " (file line nnn)".
2277 * gdb.texinfo: Document.
2280 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2282 Frozen for gdb-3.92.6 release.
2284 README, WHATS.NEW: Update for 3.92.6 release.
2286 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2287 coffread.o from configs since it is now built by default.
2288 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2289 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2290 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2291 from configs since it is now built by default.
2293 Makefile.dist: Update for release 3.92.6. Handle files that
2294 have been moved to ../include, ../getopt, or ../bfd. Add
2295 saber.suppress and tests directory. Add config.status to
2296 the release (it will say "none").
2298 coredep.c: Minor formatting fixes.
2300 These changes were made in early December but only checked in now:
2301 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2302 nindy-share/nindy.c: lint
2303 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2304 register values coming back from the target; we store values
2305 in target byte order everywhere.
2307 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2309 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2311 * valprint.c (cplus_val_print, val_print_fields): New functions,
2312 which print C++ objects. They conspire to avoid printing a
2313 virtual base class more than once, following all the twists and
2314 turns of C++ virtual base rules.
2315 (val_print): Call the above rather than do it by hand.
2317 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2318 symbol file, not for added files like shared libs. This really
2319 needs to be generalized to a timestamp per file.
2321 * core.c (cleanup_core): Avoid coredump if no core file.
2323 * config.gdb: Accept -host or -target in place of +host or
2326 * coffread.c (find_linenos): Avoid desupported BFD interface
2327 to line numbers. We still read them manually rather than using
2328 BFD's "generic" features.
2330 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2332 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2334 * Makefile.dist: Eliminate use of $< in explicit targets.
2336 * readline/Makefile: Use $< rather than $*.c, which does not
2337 include the VPATH in GNU Make.
2339 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2340 copies of tconfig/i960, added for global configuration
2341 compatability. All i960 versions can read both coff and b.out.
2343 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2344 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2347 * TODO: Think of more things to do.
2349 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2351 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2352 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2353 64-bit float conversion.
2355 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2356 equivalent to sun?os4 so global config works.
2358 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2360 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2362 * main.c: Only declare linesize once; declare pagesize not at
2363 all, since it is never used.
2364 (main): Clear newly allocated line before it is used.
2366 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2368 Further stabilization for the Intel 960.
2370 * Makefile.dist: Parameterize the location of the "include"
2371 and "bfd" directories, as well as "getopt". Add symfile.c.
2372 Link in both dbxread and coffread. Fix up "make depend" to
2373 rewack the locations of include, bfd, and getopt in its output.
2375 * README: Document moving include files, improve some of
2378 * coffread.c: Move common code out to symfile.c. Change
2379 symbol_file_command style interface to use new *_symfile_init
2380 and *_symfile_read interface under BFD. Use BFD internal
2381 info to locate line table, symbols, etc.
2383 * core.c (core_fetch_registers): Rename to get_core_registers
2384 to avoid confusion with fetch_core_registers.
2385 (register_addr): Move to coredep.c, which is already machine
2386 dependent. This leaves core.c pretty clean of dependencies.
2388 * coredep.c (register_addr): Accept this routine from core.c.
2390 * dbxread.c: Move common code (with coffread.c, etc) into new
2391 symfile.c. Each psymtab now contains a pointer to the
2392 format-dependent function that knows how to read it in. Make
2394 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2395 (process_one_symbol): Add code to complain about a "compiler bug
2396 we muzzle here", if we actually see it.
2398 * eval.c (evaluate_subexp): Insert missing "break" statements
2399 in code that determines whether a variable is an lvalue in
2400 memory, register, or whatever. I detected this via a compiler
2401 bug in which it *almost* mashed out the whole switch statement.
2403 * gdb-int.texinfo: Add minor sections on configuring gdb for
2404 release, and about the README file.
2406 * infcmd.c (registers_info): Fix formatting somewhat. Still
2407 not as pretty as before, but it handles byte swapping.
2409 * remote-nindy.c: If data cache routines are interrupted while
2410 waiting for the remote end, be sure that any uninitialized cache
2411 blocks are on the free list, not on the valid list!
2413 * symfile.h: Flesh out this header file with all the various
2414 routines and variables that have been merged in from dbxread.c
2415 coffread.c, and symtab.c to symfile.c.
2417 * symfile.c: New file, containing code common to dbxread.c,
2418 coffread.c, and some code from symtab.c. All generic code for
2419 reading symbol files should be in here now.
2420 (unrecord_misc_function): Remove unused function.
2422 * symtab.h: Remove file-reading things to symfile.h.
2424 * symtab.c: Remove file-reading things to symfile.c.
2426 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2427 to decode i960 fault types.
2429 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2430 target.c: Change type of the "resume" function from int to void,
2431 since its result was never used.
2433 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2435 * main.c: Replace "stupid" with "caution"; you now "set caution
2438 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2440 * infcmd.c (do_registers_info): Call val_print to deal with the
2441 byte order of the registers being printed. FIXME, this makes
2442 the formatting of the output uglier.
2444 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2445 defined, call it for signals the debugger doesn't itself use.
2446 The i960 uses this for more detailed fault information.
2448 * remote.c (remote_open): If arg is null, print help rather than
2451 * sparc-xdep.c (register_valid): Avoid declaring size, since
2452 various modules will think of various sizes depending on the
2453 architecture of their tm-file. FIXME, we need protection against
2454 actually entering one of those modules, which would clobber
2455 storage if not for the target architecture compiled into gdb.
2457 * stack.c (up_command, down_command): Always print the frame
2459 (up_silently_command, down_silently_command): New commands
2462 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2464 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2465 more parameters than it used to.
2467 * findvar.c (registers): Increase slop to 256 bytes, which should
2468 protect us against even most RISC machines with large register
2470 (locate_var_value): Move declaration inside related ifdef.
2472 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2473 throughout, to avoid throwing away buffered input from the board.
2474 (nindy_wait): Supply_register takes addr_of_value, not value.
2475 (i960_print_fault): Renamed from i80960_fault.
2476 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2477 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2479 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2480 we can set the PC in the call to proceed(). Unpush nindy_ops
2481 before pushing it on top, to avoid message to user. Eliminate
2482 commentary from Unix machines that just misleads here.
2483 (reset_command): Fix error message to suggest target command.
2485 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2487 Release 3.92.5 as frozen.
2489 Stabilize the merged release...with help from lint, Saber C,
2492 Everywhere: Add include files needed to declare return types
2493 of functions called.
2495 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2497 * breakpoint.h: Add undeclared breakpoint functions, and some
2498 functions for display handling since I couldn't think of a better
2501 * breakpoint.c (insert_breakpoints): Make code for disabling
2502 shared library bkpts more likely to work. It's used when we
2503 rerun a program and stop before the shared library has been
2505 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2506 cast from pointer, so it squeezes through catch_errors.
2507 (bpstat_stop_status): Fix logic broken some time ago. We now
2508 always create a bpstat if the stop address matches a breakpoint,
2509 even if we don't stop there -- just like the old code used to do
2510 before I got my fingers into it (sigh).
2511 (breakpoint_1): Print "ignore count" after "stop only if"
2512 condition, since that's how it actually works.
2513 (mention): Handle watchpoints as well as breakpoints.
2514 (watch_command): use set_raw_breakpoint and mention to do most
2515 of the work (and initialize all the fields!). Only pass one
2516 arg to parse_c_expression, since that's all it takes.
2518 * command.c (not_just_help_class_command): Rename arg to args
2519 since we ignore "unused argument" warnings on vars named "args".
2520 inflow.c (child_terminal_info): ditto.
2521 infptrace.c (kill_inferior): ditto
2522 main.c (catch_errors, version_info, quit_command, pwd_command,
2523 source_command, dump_me_command, editing_info,
2524 set_history_size_command, set_history, show_history,
2526 stack.c (locals_info): ditto
2527 target.c (target_files_info): ditto
2528 valprint.c (set_input_radix, set_output_radix): ditto
2530 * core.c: Remove old variables for handling core and exec file
2531 sections (data_start, data_end, stack_start, stack_end,
2532 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2533 text_end, exec_data_start, exec_data_end, text_offset,
2534 exec_data_offset, data_offset, stack_offset). They're
2535 superseded the more general build_section_table and
2537 (get_exec_file): Mention the `file' command.
2538 (read_memory_check): Rename to memory_error, and only call it
2539 in the case of an actual error.
2540 (read_memory, write_memory): call memory_error.
2541 (core_fetch_registers): Register section name is ".reg".
2543 coredep.c: Remove a bunch of crud now that all this file does
2544 is pull the registers out of a core file.
2545 (fetch_core_registers): Rewrite to actually work, I hope.
2547 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2548 Replace index() with strchr(). Remove all the pre-BFD macro
2549 definitions for accessing the symbol file.
2550 (struct dbx_symfile_info): Encapsulate the information that
2551 dbx_symfile_init needs to pass to dbx_symfile_read in this
2554 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2555 dbx_symfile_discard): Rearrange symbol file reading to divide
2556 the format-specific part from the format-independent part,
2557 leaving the format-independent part such as file name expansion
2558 and opening in symtab.c. This replaces
2559 partial_symbol_file_open and partial_symbol_file_read.
2560 Symbol_file_read, add_file, add_file_target_command,
2561 add_file_addr_command move to symtab.c. Pass an explicit
2562 "mainline" flag for when reading the main symbol table, rather
2563 than relying on the offset address to be zero or nonzero.
2565 (dbx_symfile_read): Don't allow void *'s to be printed as
2567 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2568 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2569 macro" debug version really work.
2570 (read_dbx_symtab): Remove unref'd parameter inclink.
2571 Avoid swapping N_SLINE symbols, for speed.
2572 Merge N_TEXT!N_EXT case with the other external symbol
2573 definitions' case. Add comments.
2574 (start_psymtab): Allocate the symfile name in the psymtab on
2575 the psymbol_obstack, rather than using the caller's storage.
2576 (end_psymtab): Only allocate a dependencies list if there are
2578 (psymtab_to_symtab_2): Use BFD when reopening file to read
2579 its symbols for real.
2580 (read_struct_type): Add FIXME comments where it needs work
2582 (read_huge_number): Add FIXME about overflows.
2583 (read_range_type): Add FIXME about comparing a long to 1<<32.
2585 * coffread.c: Minor changes to move things closer to the new
2586 regime with symtab.c and dbxread.c Major work is still needed
2589 * exec.c (exec_file_command): Remove old variables (see core.c
2591 (xfer_memory): If memory transfer is right at the end of a
2592 section, don't lose.
2594 * findvar.c (get_saved_register): If value is in a real
2595 register, LVAL is lval_register, not lval_memory.
2597 frame.h: Declare print_sel_frame and record_selected_frame.
2599 gdb-int.texinfo: New file, for GDB internals documentation.
2600 Very simple, unformatted doc of cleanups is there for now.
2602 gdbcore.h: Remove obsolete variables that described a.out
2603 section addresses and offsets. (See core.c above.)
2604 Declare fetch_core_registers and registers_fetched.
2606 getopt.c: Declare char *alloca(); even on SPARC.
2608 infcmd.c (run_command): Call target_kill rather than
2610 (step_command, next_command, stepi_command, nexti_command):
2611 Declare from_tty parameter even though we don't use it.
2612 (run_stack_dummy): argument BUFFER is a char array, not
2613 a pointer to REGISTER_TYPE.
2614 (finish_command): using_struct_return needed a value *,
2615 not a struct symbol *.
2617 * infptrace.c (child_xfer_memory): To avoid dependency on
2618 where sections are in memory, try PT_WRITE_D and if that fails,
2619 try PT_WRITE_I. Most Unixes don't care which you use.
2621 * infrun.c (step_resume_break_shadow): Change to array to
2622 match other breakpoint shadow storage.
2623 (clear_proceed_status): Pass address of bpstat to
2624 bpstat_clear, not the bpstat itself.
2625 (child_create_inferior): FIXME comment about if the child
2627 (start_inferior): Remove old function.
2628 (child_open): Use target_kill rather than kill_inferior.
2629 (wait_for_inferior): Ditto.
2630 (insert_step_breakpoint, remote_step_breakpoint): Use
2631 new step_resume_break_shadow.
2633 * inftarg.c (child_wait): If all child processes die,
2634 pretend that the one being waited for exited with signal 42.
2636 * main.c (command_line_input): When scanning for comments,
2637 don't coredump on unclosed quotes.
2638 (quit_command): Use target_kill rther than kill_inferior.
2639 (_initialize_main): Rename class_user from "user" to
2642 * printcmd.c (print_command_1): Initialize "fmt" if no format
2643 is specified by the user.
2644 (print_frame_args): Only add to args_printed if we are
2645 actually fetching args from the stack (avoiding undefined
2647 (_initialize_printcmd): Remove bogus \{ from string.
2649 * remote-eb.c (eb_open): Avoid coredump on no argument.
2651 * remote-nindy.c: Bring out of Intel environment into new
2652 target environment. Remove all conditional compilation on
2653 I80960. Massive hacking throughout.
2654 (nindy_xfer_inferior_memory): New routine stolen from
2656 (nindy_create_inferior): New routine pieced together, probably
2657 not quite working yet.
2658 (nindy_ops): New target_ops struct for nindy.
2660 * remote-vx.c: Use write_memory rather than target_write_memory
2661 to get error checking.
2662 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2664 (vx_create_inferior): Use target_terminal_ours...
2666 * signame.c (_initialize_signame): Always initialize, since
2667 we need the table for things other than psignal.
2669 * solib.c (solib_add): Use symbol_file_add, not add_file.
2670 (solib_address): Return boolean result rather than struct
2671 pointer which nobody else knows the type of.
2673 * sparc-tdep.c, valops.c: Use write_memory rather than
2674 target_write_memory, to get error checking.
2676 * stack.c (locals_info, catch_info, args_info,
2677 get_selected_block, frame_command, up_command): Use
2678 target_has_stack, rather than have_inferior_p or
2681 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2683 * symfile.h: New file, defining the interface between the
2684 generic and object-file-specific symbol reading code.
2686 * symtab.c: Move generic symbol-reading interface to symtab.c,
2687 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2688 table to map BFD targets to symbol-reading modules in GDB.
2689 Change index to strchr.
2690 (lookup_struct_elt_type): Use error() rather than hand-made
2691 simulations thereof.
2692 (lookup_partial_symbol): Speedup slightly when length == 0.
2693 (symbol_file_add): New function.
2694 (symbol_file_command): Call it.
2695 (symfile_open, symfile_init): New function.
2696 (add_file_target_command, add_file_addr_command): moved from
2699 * target.c (target_command): use target_kill.
2701 * target.h (target_files_info): Don't declare, never called
2704 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2705 files to determine stack end address.
2707 * valarith.c (value_x_binop, value_x_unop): Change error message
2708 to be more useful. Pass proper argument to value_struct_elt.
2710 * valops.c (value_assign): FIXME comment that long long
2711 bitfields will break here.
2713 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2714 Update `make saber_gdb' to work better.
2716 * TODO: A woman's work is never done.
2718 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2719 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2720 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2721 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2722 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2723 valops.c, valprint.c, exec.c: Lint.
2726 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2728 Continuing Intel 960 port merge of GDB.
2730 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2731 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2732 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2733 Wack over "make depend" so it handles files in subdirectories
2734 vx-share, nindy-share, bfd, and in the current directory.
2736 * blockframe.c (get_prev_frame_info): Remove fatal error
2737 if stack not defined.
2739 * core.c (core_open, core_detach): New functions that handle
2740 the old "core-file" command as "target core" and "detach" instead.
2741 (core_file_command): Call them.
2742 (core_xfer_memory): Use common routine xfer_memory.
2744 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2745 dbxread now uses bfd for everything but symbol reading itself.
2746 BFD internals are used to drag out the relevant file offsets.
2747 (partial_symbol_file_open): Change args all around for BFD.
2749 * symtab.c: Rename "value" to "val" everywhere, so we can
2751 (symbol_file_command): New command, moved from dbxread.c
2752 and coffread.c. It uses BFD to read the file, then vectors
2753 based on its type, to dbx or coff symbol readers.
2754 * symtab.h: Extern a few vars for symbol_file_command.
2756 * target.h: Breakpoint takes a char * save area, not a char **.
2758 * valprint.c (val_print): When unpacking bitfields, offset
2759 the address in gdb of the value, if it is declared with a shorter
2760 type. Remove the last "runtime kludge test" of host byte order.
2762 * utils.c: Remove old my_bfd_read routine.
2764 * stack.c (frame_info): Use target_has_stack. Print program counter
2765 register's actual name rather than "pc", since it's called the
2766 "ip" (instruction pointer) on the i960 (sigh).
2768 * target.c (target_command): Add command for selecting a target
2769 type and calling its open routine. This is used for initiating
2770 communication with a particular target, in a generic way.
2772 * tm-i960.h: Update for modern gdb. Remove semicolons from
2773 various macros. Handle reading struct return convention, and
2774 error-out attempts to return structs with the "return" command.
2775 Be sure gdb doesn't think we know how to call functions in the
2778 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2779 to i960_xxx in lower case.
2780 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2781 not being defined yet.
2783 * remote.c (remote_open): Call start_remote to initialize
2784 wait_for_inferior during open.
2785 (remote_xfer_inferior_memory): Return length written rather
2788 * remote-vx.c (target_command -> vx_open): Use new generic
2790 * remote-eb.c, inftarg.c, exec.c: ditto.
2792 * infrun.c: Fix comments.
2793 (attach_program -> child_open): Use new generic target command.
2794 (wait_for_inferior): Clear saved register values before target_wait,
2795 so target_wait can set some of them if convenient.
2797 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2798 Return success indicator, not void.
2799 (child_xfer_memory): Avoid fetching initial word if we'll
2800 overwrite it anyway.
2802 * infcmd.c (attach_command): Use new generic target open routine.
2803 (_initialize_infcmd): Update doc on attach and detach commands.
2804 (do_registers_info): Merge in a byte-order problem as a FIXME
2807 * findvar.c (find_saved_register): Avoid problem in current frame.
2808 (read_relative_register): Ditto.
2809 (write_register): Convert byte order on the way out.
2811 * exec.c (file_command): Add.
2812 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
2813 (xfer_memory): Common function between core_xfer_memory and
2815 (exec_xfer_memory): Use it.
2817 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
2819 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
2820 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
2821 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
2823 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
2825 Merge Intel 960 port of gdb, continuing...
2827 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
2828 symbol_file_command): Pass from_tty arg to hush 'em up.
2830 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
2831 Add magic numbers for 960 COFF format.
2833 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
2835 Merge Intel 960 port of gdb, from Intel "1.2" release.
2837 CHANGE_LOG entries from their port, which was based on

2841 Remove temp file if download is interrupted.
2843 Wed Aug 1 09:08:33 PDT 1990
2844 Now uses binary protocol to talk to NINDY.
2845 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
2846 Times out after 5 seconds when trying to talk to NINDY.
2848 Tue May 29 12:54:49 PDT 1990
2849 Added variable baud rate (-b switch).
2850 Source code reorganization.
2852 Thu Apr 26 11:09:55 PDT 1990
2853 More cleanup of batch mode; specifically, execute "-s", "-e", and
2854 "-se" switches as soon as they are encountered on the invocation line.
2856 Fri Apr 20 13:47:15 PDT 1990
2859 Thu Apr 19 09:54:28 PDT 1990
2860 Add 'reset' command.
2862 Wed Apr 18 09:48:07 PDT 1990
2863 After opening remote tty, wait for 1 second to go by without input
2864 from it before trying to talk to NINDY (fixes problems with the
2865 Heurikon HK80/V960E).
2867 Mon Apr 4 16:33:05 PDT 1990
2868 Some output was not being suppressed in 'batch' mode.
2870 Thu Mar 22 15:31:11 PST 1990
2871 Ask user if old symbol table should be deleted when new file is
2874 Allow user to run a program downloaded before gdb960 was brought up.
2876 Correct "exec-file" help message for i80960 context.
2878 Correct bug in calculating user space address: could occasionally
2879 corrupt user program.
2881 Make sure to zero low-order bits in rip's because of bug in 960CA
2882 A-step part: could cause operation faults when "next"ing across
2885 Correct bug that made it impossible to get source line numbers for
2886 code loaded at addresses higher than 0x7fffffff.
2888 Wed Jan 10 12:43:22 PST 1990
2889 Open remote tty for exclusive use.
2891 Fri Jan 5 12:14:42 PST 1990
2892 Correct disassembly (CA manual was right after all):
2893 opcode for sysctl is 0x659
2895 Mon Oct 23 12:03:04 PDT 1989
2896 Use G960BASE and G960BIN environment variables to find 'sx' utility.
2898 Mon Oct 16 14:15:09 PDT 1989
2899 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
2901 Mon Oct 2 15:56:31 PDT 1989
2903 Added 960CA disassembly support.
2905 To simplify maintenance:
2906 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
2908 - eliminated opcode.h: incorporates tables into i960-pinsn.c
2909 - moved 960-specific routines from i960-pinsn.c to i960-md.c
2910 - made disassembly interface identical to that in gdmp960.
2914 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
2916 * target.h: Allow targets to stack. Add target_has_memory,
2917 _registers, etc. Restructure memory access and "info files"
2918 to walk the target stack.
2919 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
2920 target.c: Change tables to match target.h.
2921 * inflow.c (child_mourn_inferior): pop child_ops.
2922 (generic_mourn_inferior): Use new has_stack flag.
2923 * infptrace.c (child_xfer_memory): New memory regime.
2924 * inftarg.c (child_files_info): New "info files" regime.
2925 * remote-eb.c: New memory regime, new info files.
2926 * remote-vx.c: New memory regime, new info files. Now use
2927 separate targets for VxWorks attachment to machine, and
2928 actually running a process under VxWorks, since one has
2929 stack & execution & regs and the other doesn't.
2930 * remote.c: New memory regime, new info files.
2931 * sparc-xdep.c (fetch_core-registers): New memory regime.
2932 * target.c: New routines and support for stacked targets,
2933 new memory regime, new info files regime.
2936 Generalize section handling for an arbitrary number of sections,
2937 including use of the new BFD (binary file) library.
2938 * gdbcore.h: Add struct section_table.
2939 * exec.c (build_section_table): Iterate all sections and
2940 record what gdb needs to know about them.
2941 (exec_command): Use it.
2942 (exec_xfer_memory): Use the table.
2943 (exec_files_info): Print the table.
2944 * core.c (core_file_command, core_xfer_memory, core_files_info):
2946 * source.c (find_source_lines): Use bfd_get_mtime.
2947 * dbxread.c: Quick changes to make it compile with new BFD.
2948 * utils.c (error): Avoid using bfd_error in generic routines.
2950 * core.c (core_fetch_registers): Get from the ".regs" section of
2952 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
2954 * inferior.h (attach_flag): Export.
2955 * infcmd.c (run_command): use new target_create_inferior.
2956 * infrun.c (child_create_inferior): Don't return result.
2957 * Makefile.dist (VERSION): 3.91.4.
2959 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
2961 * breakpoint.c (bpstat_num): Handle breakpoints which have
2962 since been deleted, such as temporary breakpoints.
2963 infcmd.c (program_info): ditto.
2965 * core.c (core_file_command): Display the frame where the core
2970 * remote-vx.c (target_command): Merge in target command from
2971 targ-vx.c. A few other cleanups.
2973 * TODO, Projects: Lots more stuff to do...
2975 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
2977 Massive changes to wall off the remote-debugging interface
2978 behind a function vector. The port to handle VxWorks targets
2979 is also part of this.
2981 All files: Replace references to renamed functions,
2982 remove references to remote_debugging, remove references to
2983 have_include_file, have_core_file in favor of target_has_stack,
2984 target_has_memory, etc.
2986 * Modularize the breakpoint interface.
2987 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
2988 a breakpoint instruction.
2989 breakpoint.c: struct breakpoint's shadow_contents now sized as
2991 (insert_breakpoints): Vector to target to install breakpoints.
2992 (remove_breakpoints): Vector to target here too.
2993 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
2994 sparc-tdep.c (single_step): Use new breakpoint interface for
2995 the single-step breakpoints.
2996 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
2997 New file, contains routines to insert and remove breakpoints by
2998 reading out the old contents and later replacing them. This is
2999 how ptrace breakpoints work, and many remote systems as well.
3001 * tm-vxworks68.h: New config file, overrides a few things for
3002 Wind River's preferences.
3004 * target.h: New file, for transfer vector used to talk to the
3005 inferior (child, attached, core, exec, remote, etc). All accesses
3006 to the thing being debugged should come through these vectors.
3007 target.c: New file, routines to handle transfer vector.
3008 (various files): Add transfer vectors XXX_ops for the various
3009 targets and pseudo-targets (core files, etc) we support.
3011 * breakpoint.c (bpstat_stop_status): Further explorations of
3012 watchpoints and why things don't work all the time.
3013 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3015 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3016 the local gdbinit if it doesn't already have it.
3018 * core.c (core_ops): add and install.
3019 Allow core debugging without exec file.
3021 * dbxread.c (free_and_init_header_files): Merge two fns.
3022 (end_symtab): Free named symbol table when a new version comes in.
3023 (read_dbx_symtab): Relocate all kinds of symbols with base
3024 address. First step toward handling different text, data, bss
3026 (add_file_addr_command): Renamed add_file_command.
3027 (add_file_command): Vector to remote handler.
3028 Add "load" as an alias for "add-file" command.
3030 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3031 non-returning functions.
3033 * exec.c: Add exec_ops, and push it as a target when an exec
3036 * infcmd.c (run_command): Pass executable file name and arg list
3037 separately when starting an inferior. Permit "run" when no exec
3038 file is specified, for VxWorks.
3039 (detach_command): Move to child_detach in inftarg.c.
3041 * inftarg.c: New file. Unix-child-specific routines, and the
3042 child_ops structure.
3044 * inferior.h (registers): Export "registers" as the way for
3045 target dependent register handlers to find gdb's local copy of
3046 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3047 since it is now used by places that want wait_for_inferior to
3048 handle the grunge but want to see every trap from the inferior.
3050 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3051 Eliminate remote_debugging hooks in terminal handling.
3053 * infrun.c: Replace start_inferior with child_create_inferior.
3054 Move all the hair of Unix shells and ptrace idiosyncracies into
3055 child_create_inferior, so remote handlers don't have to deal.
3056 Remove running_in_shell. Rename stop_after_attach to
3057 stop_soon_quietly, and use it in a few other places where we want
3058 to just call wait_for_inferior and get control back on the first
3059 trap. trap_expected now never takes a value > 1.
3060 (init_wait_for_inferior): Initialize static vars when a new
3063 main.c (gdbinit): Add new hook for .gdbinit file name, let
3064 it be overridden by config files as GDBINIT_FILENAME.
3065 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3066 Both of these are used for VxWorks gdb.
3068 mcheck.c: rename include file "gmalloc.c" to avoid problems
3069 with system include file "malloc.c".
3071 param-no-tm.h: New include file, same as param.h but does not
3072 include the default "tm.h" file. This is used in files where
3073 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3075 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3077 remote-vx.c: New file, VxWorks remote debugging support. Uses
3078 RPC routines that are shared with the target system, in directory
3081 remote.c: Vectorize remote interface.
3083 source.c: Globalize source_path, and make an alias "l" for "list"
3084 since we now have the "load" command.
3086 sparc-xdep.c: Use new param-no-tm.h.
3088 symmisc.c (free_named_symtab): Add new function from Wind River.
3089 However, ifdef it out for now while we think about what it should
3092 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3094 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3095 non-Unix-children handle this with their own code in the target
3098 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3099 source and target lists. Add vx-share to default list of include
3100 directories. Add new files to src and target lists: mem-break,
3101 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3102 ${srcdir} versions of munch and createtags are used.
3104 * valops.c (find_function_addr): Split out of call_function.
3105 (call_function_by_hand): Rename call_function; this function
3106 calls functions in the target by laboriously patching the target
3107 word-by-word with the right stack, args, regs, etc.
3110 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3112 Handle AMD 29000 a bit better.
3114 * remote-eb.c (readchar): Mask received char log to make it readable.
3115 (remote_start): Pass arguments down to executing program.
3116 Make startaddr unsigned.
3117 infrun.c (start_inferior): Accept args, pass them to
3119 infcmd.c (run_command): Pass args down to start_inferior.
3121 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3122 the target object file format.
3123 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3125 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3126 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3128 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3130 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3131 * TODO: We did a few things, we have more to do though.
3133 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3134 * inflow.c (inferior_died): Clear deferred stores.
3136 * Debug problems with dummy frames and calls to the inferior.
3137 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
3138 * sparc-tdep.c (do_restore_insn): Simplify.
3139 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3140 (sparc_push_dummy_frame): Simplify and fix what we push.
3141 (sparc_pop_frame): Slightly more hair here, deciding whether
3142 we are restoring a saved PC or returning to a return address in %i7.
3143 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3145 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3146 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3147 * obstack.h (chunkfun): ditto.
3148 * defs.h (xmalloc, xrealloc): ditto
3150 * utils.c (quit): Grab the terminal from the child if necessary.
3152 * inflow.c (term_status_command): Rename to term_info, change
3155 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3156 (is_delayed_branch): Speed up.
3157 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3158 Still missing some float ops, and needs testing.
3160 * Support for input and output radixes other than base 10
3161 * defs.h (input_radix, output_radix): Declare.
3162 * expread.y (yyparse, parse_number): Handle changes of input
3163 radix, and ambiguous names-or-numbers in radixes >10.
3164 * printcmd.c (print_scalar_formatted): Print formatted hex
3165 numbers in varying column widths.
3166 * valprint.c (val_print): Use output_format to print scalar ints.
3167 (set_input_radix, set_output_radix, set_radix): Create.
3168 (set_output_radix): Set output_format from output_radix.
3169 (_initialize_valprint): add `set radix' but leave the others off.
3171 * main.c (execute_command): Let stupid questions be turned off.
3172 (_initialize_main): Handle "set stupidity", etc.
3174 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3175 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3177 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3179 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3180 bfd stuff is still screwed up, but with some manual work, it
3183 * breakpoint.c (bpstat_do_actions): Start over if a command
3184 proceeds the inferior, since the inferior will have stopped and
3185 will need to have its new stop-actions taken care of.
3187 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3188 compiler fits, simplify it.
3190 * gdb.texinfo (directory command): Doc new dir command.
3191 source.c (directory_command): "dir" now puts things on the front
3192 of the path, moves dups up front, and handles multiple names
3193 on the command line, inserting each one in order. It also
3194 blows away cached line and full_filename info.
3196 * stack.c (backtrace_command): Skip "more stack frames follow"
3199 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3200 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3201 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3202 The only odd one was Gould NP1, which had defined vprintf to
3205 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3206 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3207 variable, inspect_it.
3208 valprint.c (print_string, val_print): Use the global inspect_it
3209 to indicate whether to print in Epoch style or normal style.
3211 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3213 * printcmd.c (call_command): add an alias for the "print" command
3214 which runs expressions and doesn't print the result if void.
3215 (print_command_1): implement it.
3217 * command.c: Remove #if 0'd code. Initialize all the fields
3218 in add_cmd (). Rename do_nothing_command to
3219 not_just_help_class_command, and make it externally visible.
3220 command.h: add user_commands to struct.
3221 * main.c (define_command): Don't overload c->function with a char
3222 string as well as a function pointer.
3224 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3225 calling convention of value_struct_elt () that got dropped in
3228 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3229 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3231 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3233 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3234 until a good time (e.g. when we are about to run the child),
3235 saving ptrace calls.
3236 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3237 * tm-sparc.h: define DO_DEFERRED_STORES.
3239 * sparc-xdep.c (store_inferior_registers): when storing float
3240 registers, don't store stack regs too. When storing the SP,
3241 however, DO store the stack regs too. This fixes a bug in which
3242 the dummy frame is not recognized when a call_function finishes,
3243 because its frame pointer (in the stack regs) was never
3245 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3246 even though we don't know how to read them from an inferior.
3247 valops.c (call_function): Comment about storing SP.
3249 * infrun.c (save_inferior_status): Save away the original bpstat
3250 chain so it can be restored later. Install the copied version for
3251 use by whoever saved the status. It will be blow away by
3252 restore_inferior_status, and the original chain restored. This is
3253 important for people who have pointers into the original.
3255 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3256 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3257 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3260 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3262 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3263 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3264 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3266 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3268 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3269 Store the baseclasses in a type struct starting from array element
3270 0 rather than from the unusual array element 1.
3272 dbxread.c: the above.
3273 (virtual_context): Add
3274 Read new debug information about which virtual function table
3275 a virtual function is from, and store it in fn_field.fcontext.
3277 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3278 TYPE_FN_FIELD_STATIC_P.
3280 symtab.c: the above.
3281 valops.c: the above. Handle pointer casts of object *'s.
3282 (search_struct_method): Add.
3283 (value_struct_elt): First arg is now a pointer to a value, and is
3286 valprint.c: the above.
3287 values.c (value_virtual_fn_field): Add type arg. Handle
3288 offsetting to the proper object when calling virtual fns.
3290 (baseclass_addr): Add valuep arg.
3292 * README: Document the current state of BFD config (missing).
3293 * TODO, ChangeLog, Makefile.dist: Roll version.
3294 * WHATS.NEW: Add summary of changes since 3.5.
3296 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3298 * dbxread.c (read_struct_type): Clear bit vectors whenever
3300 symtab.c (B_CLRALL): define.
3302 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3303 using == rather than =. Huh... This fixes the dreaded problem
3304 wherein builtin_type_int becomes TYPE_CODE_FLT.
3306 * core.c (info_files): Show the inferior pid.
3308 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3309 already knows how to look in the source directory.
3311 * Remove psymtab hair from many places. Remove duplicated code
3312 for searching symbol tables. Hide psymtabs from most places.
3313 Make it fast to get from a psymtab to its symtab.
3315 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3316 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3317 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3318 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3319 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3320 new symtab completely. New psymtabs get symtab pointer
3321 initialized to zero. Remove MI warning printf.
3322 symtab.h: Comments. Add psymtab to symtab pointer.
3323 (PSYMTAB_TO_SYMTAB): New macro.
3324 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3325 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3327 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3329 (print_frame_info): Avoid special-casing symbols that have not yet
3332 * source.c (open_source_file): Quick path if we have already
3333 located the source file by its full name.
3335 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3336 find_pc_psymtab. When a name is found in the misc function
3337 vector, search the symbol table for its mangled name, not the
3338 name that the user typed.
3340 * bfd.h: Fix missing comment terminators, make #endifs match.
3342 * valarith.c (value_less): Handle unsigned int comparisons.
3343 Add FIXME about pointer compares, which assume host and target
3344 pointers are the same.
3346 * command.c (do_nothing_command): lint
3347 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3348 fix comments on debug symbol format for visibility. Actually set
3349 visibility of symbols.
3350 main.c (echo_command): lint; use <readline/history.h>.
3351 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3352 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3353 pointing past end of allocated memory; saber complains.
3354 obstack.h: Declare the external functions that we use.
3355 valarith.h: use <string.h>
3356 solib.c (solib_add): lint.
3358 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3360 * main.c (initialize_main): Default info_verbose to off, now that
3361 symbol reading is fast.
3362 (quit_command): Avoid clobbering exec_bfd while quitting.
3364 * Initial BFD (binary file diddling library) merger:
3365 coffread.c: Change AOUTHDR to struct exe_hdr.
3367 core.c: initialize initialized data at compile time.
3368 (core_file_command): Move from coredep.c, convert to bfd.
3369 (xfer_core_file): Convert to bfd.
3370 exec.c (exec_file_command): use bfd routines.
3372 mips-tdep.c: Remove exec_file_command and friends.
3375 * coredep.c: (fetch_core_registers) Convert core_file_command to
3376 fetch_core_registers.
3377 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3379 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3380 (my_bfd_read): More bogosity, which I don't think we call.
3381 (program_name): Remove this atrocity asap!
3383 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3386 values.c: allocate_repeat_value was not clearing the
3387 optimized_out field.
3388 (value_static_field): minor stylistic fix (wrong macro was used).
3389 valops.c (value_struct_elt_for_address): didn't work for C++
3392 * signame.c (_initialize_signame): Initialize signal names once.
3394 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3395 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3396 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3398 * remote-eb.c: Support user-settable baud rates on the serial port.
3400 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3402 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3404 * tconfig/sun3os4: Remove warning about native assembler,
3405 since it also occurs in the xconfig file.
3407 * findvar.c (registers): Allocate some slop after `registers'
3408 to prevent stray accesses from trashing the next variable.
3410 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3411 on the sun-3, by changing the #ifdef from `sun3' (which is not
3412 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3413 vars, which happened to follow `registers' in the executable.
3415 * readline/history.c (history_search): Heed gcc-2's advice
3416 and parenthesize && inside ||).
3418 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3419 tm-29k.c: Insert FSF copyright headers.
3421 * remote-eb.c: Better comments.
3423 * Makefile.dist: Update to 3.91.6.
3424 * TODO: note PREPARE_TO_STORE problem.
3426 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3428 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3430 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3432 * infrun.c (wait_for_inferior, at end): Don't set up
3433 prev_* if the inferior no longer exists.
3435 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3436 CANNOT_EXECUTE_STACK.
3437 valops.c (call_function): Use it.
3439 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3441 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3442 infrun.c (wait_for_inferior, 2 places): Use it.
3444 * values.c (value_being_returned): Only use
3445 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3447 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3448 right thing for remote-eb.c.
3450 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3451 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3453 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3454 (FRAME_FIND_SAVED_REGS).
3456 * findvar.c ({fetch,store}_registers): Check for
3457 REMOTE_{FETCH_STORE}_REGISTER macro.
3459 * findvar.c (get_saved_register): Add argument lval and
3460 change meaning of argument addr.
3461 findvar.c: Change calls to get_saved_register to reflect
3462 new calling convention.
3463 valops.c (value_assign): Use get_saved_register instead of
3464 find_saved_register.
3466 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3468 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3469 an (uninitialized) pointer to one. Use "&" when passing it
3472 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3474 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3477 * coffread.c (symbol_file_command): Put semicolon after
3479 Put safe_to_init_tdesc_context in #if defined (TDESC).
3480 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3481 coffread.c: #include <sys/stat.h>.
3482 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3483 Add missing ')' in check for "lc%" and friends. Remove
3485 Declare read_one_sym() at top of file.
3486 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3487 MC68WRMAGIC can have the same value without causing a duplicate
3490 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3492 * Allow a Makefile to be built without building the
3493 tm and xm file links that screw up builds in subdirectories.
3494 This is done with `config.gdb none', then you can do things
3495 like `make gdb.tar.Z'.
3496 * tconfig/none: Config file for no target system
3497 * xconfig/none: Config file for no host system
3498 * config.gdb: If no TM or XM files are called out by the
3499 host or target file, don't make links for them.
3501 * cplus-dem.c: Add documentation.
3503 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3504 simple error, so the user's gdb doesn't crash due to some object
3505 file problem (e.g. somebody is rebuilding the file out from under
3508 * printcmd.c (print_address_symbolic): demangle the symbol.
3510 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3511 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3512 (alldeps.mak): sort and uniq all results from this; duplicates
3513 hose gdb.tar.Z link building. Remove RCS files from
3514 tconfig and xconfig. Add config files for sun386. Add
3515 a few odd files to OTHERS and HFILES.
3517 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3519 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3520 Roll version number to 3.91.5. Make lint work in bindir.
3522 * README: Document cross-debugging and new file structure.
3524 * blockframe.c: Lint. Include "value.h" to declare read_register.
3525 (find_pc_partial_function): remove duplicate line.
3527 * command.h: Lint. Declare error_no_arg and dont_repeat.
3529 * tm-news.h: Remove inadvertently duplicated stuff.
3531 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3532 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3534 * config.gdb: Allow `config.gdb host target' form. Clean
3535 up previous change that printed bogus messages when you just said
3538 * core.c: #include "command.h" for lint.
3541 * main.c: Remove some casts of enums. Lint.
3548 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3550 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3551 read it from memory. This will allow us to save ptrace calls
3552 eventually. Changed caller single_step too.
3554 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3555 that we aren't going to use, saving many ptrace calls, especially
3556 when watchpointing or single stepping. Use some #define's for
3558 (store_inferior_registers): Ditto.
3559 (core_file_command): Use some #define's for constants.
3561 * tm-sparc.h: Add #define's for some register numbers, so we
3562 can eliminate the use of random constants in sparc-xdep.c.
3564 * stack.c (frame_command, print_frame_info, up_command,
3565 down_command) Remove frame_changed, since it
3566 causes a bug and doesn't seem to do anything useful. In some
3567 places it was used as a flag, in others as a stack level (?).
3569 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3570 default is to use the portable (vprintf) version rather than the
3572 * xm-news.h (MISSING_VPRINTF): Add.
3574 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3576 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3578 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3579 about linking debugged programs -Bstatic in the sun?os4 config
3580 files in tconfig and xconfig subdirectories.
3582 * main.c (main): Remove unreached exit(0) now that we exit
3585 * Create TODO file for online bug list. There are too many
3586 "little" bugs to keep track of on paper.
3588 * Change Projects file to refer to bug-gdb@cygnus.com
3589 rather than kingdon@ai.
3591 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3593 * Makefile.dist (VERSION): 3.91.4 now.
3595 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3596 (condense_misc_bunches): Add sanity check that misc_count is
3597 the same as the number of symbols in the bunch.
3599 * coffread.c: rename init_misc_bunches. Pass an argument
3600 to condense_misc_bunches (a zero).
3602 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3603 every time we are called; don't rely on our caller to do it.
3604 (add_file): Remove call to init_misc_bunches.
3606 * mipsread.c: Only warn, don't error, if unknown symbol types.
3607 This keeps an old gdb from falling on its face if it sees newly
3608 extended symbol info. Rename init_misc_bunches.
3610 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3612 * Merge in changes from Per Bothner for DECstations and other
3613 MIPS stuff. The rest is Bothner speaking:
3615 The next message is a merger of Alessando Forin's mips port with
3616 mine. I've tried to use my good if biased judgment to get
3617 the best of both. It *does* need testing.
3619 Some of the changes are general, *not* mips-specific.
3622 Didn't believe in little-endian bit order.
3623 There are still inconsistencies about whether flags
3624 like BITS_BIG_ENDIAN are integer (#if ...) or
3625 boolean (#ifdef ...). I tried to paper over them.
3627 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3628 Moved some misc_function code that was common to
3629 {dbx,coff,mips}read.c to symtab.c.
3630 In the process, I think I cleaned things up a bit.
3631 At the same time, moved obsavestring and obconcat to symtab.c.
3634 Removed obsolete condense_addl_misc_bunches (use
3635 condense_misc_bunches(1) instead).
3638 Needed to include <sys/dir>, at least on DECstations.
3640 valops.c, mips-tdep.c, tm-mips.h:
3641 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3642 conventions (when STACK_ALIGN is insufficient).
3643 Needed on mips, where doubles need 8-byte alignment,
3644 but ints only need 4.
3647 Removed cruft that was not being used.
3648 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3651 Print $ before register-names (I think that makes things a little
3653 Never print two instructions, even if one delays.
3654 Removed hex-disassemble set_cmd. (This is not mips-specific,
3655 so I think the argument is whether it is generally worthwhile or not.
3656 I'm inclined to think not, given how easy it is to
3657 convert between radixes in gdb.)
3660 This is basically Alessando's code.
3661 It doesn't use obstacks; I changed it to use obstacks
3662 in a few minor places where using malloc causes a
3663 memory leak. (Probably, more places could/should be changed.)
3664 I added record_misc_function where it was missing.
3665 In symbol_file_command and add_file_command, I tried
3666 to make the code consistent with more recent versions.
3667 Minor sylistic changes in parse_procedure.
3668 Make a .gdbinfo. psuedo-symbol point back to the real
3669 procedure symbol (using the isym field).
3672 This is basically from my port, but with a lot of details
3673 and a number of routines merged in from Alessando's version.
3674 I basically used my code "raw" backtrace (use heuristics
3675 from the actual code, rather than symbol table info) - though
3676 the idea is Alessandro's. I feel my code is a little cleaner
3677 here, particularly in being a little more flexible, such as being
3678 able to handle gcc-produced code (which it now can).
3679 It also doesn't do frame caching (which is not useful
3680 more recent gdb versions).
3681 I also used my code for push_/pop_dummy, more or less.
3682 I tried to incorporate AF's code for testing sigtramp
3683 while backtracing; I probably got it wrong.
3684 Added mips_print_register, which tries to scrunch as much
3685 information as possible on a screen...
3686 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3687 under mips-pinsn.c), I don't see anything mips-specific here,
3688 and I don't see it being all that useful anyway.
3691 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3692 Use more register names (rather than hard-cases numbers).
3694 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3696 * Hack up 3.90.11 changes:
3698 * Makefile.dist (depend): parameterize $(GCC).
3699 Add solib.c and solib.o.
3700 (readline): Fix vpath for both absolute or relative SRCDIR.
3702 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3703 Also, let the part I didn't understand at least compile so
3704 I can test the rest. FIXME.
3706 * dbxread.c: Fix thinko using strcmp.
3707 (init_psymbol_list): declare static.
3708 (partial_symbol_file_open): Comment cleanups better, avoid
3709 cleaning up the string table since the caller will do that.
3710 Move the stat for mod time into symbol_file_command, temporarily.
3711 (There should be a mod time for each symbol file, eventually,
3712 to control its rereading. FIXME.)
3714 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3715 SunOS, which gives error for shared libs otherwise. (From
3716 Schaefer, probably FIXME needs work for portability.)
3718 * solib.c: Move #include "param.h" to work.
3719 Lowercase all the Uppercase Letters In the Messages.
3720 (find_solib): Clean up inferior_so_name for debug printouts.
3721 Allow no argument, to mean all shared libraries.
3723 * symmisc.c: include param.h to get CLEAR_SOLIB.
3725 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3727 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
3728 to 3.90.11. ChangeLog entries below are from this.
3730 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3734 * Makefile.dist (HFILES): Add tm-sunos.h.
3736 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3740 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
3742 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
3744 * sparc-opcode.h Added single-operand version of rett.
3746 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3748 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
3749 Put parens around gcc_p in expansion.
3751 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3753 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
3755 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3757 * Changes for Sun shared libraries:
3758 blockframe.c (find_pc_partial_function): If a non-text symbol
3759 is found, set *address = pc - FUNCTION_START_OFFSET.
3760 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
3761 Disable breakpoints instead of giving an error.
3762 source.c (select_source_symtab): Initialize cs_pst.
3763 symmisc.c: Call CLEAR_SOLIB if defined.
3764 symtab.h: Make text{low,high} CORE_ADDR not int.
3765 (psymtab): New field addr.
3767 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
3768 (record_misc_function): Give correct type for N_DATA symbols.
3769 (condense_misc_bunches): do "misc_function_count = j" regardless
3771 Take code which is shared between symbol_file_command and
3772 add_file_command and put it into partial_symbol_file_{open,read}.
3773 Split add_file_command into add_file_command and add_file.
3774 Make psymtab_to_symtab read in the string table if the file
3776 Two new parameters to read_dbx_symtab and start_psymtab.
3777 tm-sunos.h: New file.
3779 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3781 * infcmd.c: Change cont_command to continue_command and "cont"
3784 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3786 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
3788 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
3790 * values.c (USE_STRUCT_CONVENTION): Check for structures of
3791 size 1,2,4,8 rather than size < 8.
3793 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
3794 as necessary, not just once.
3796 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3798 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3800 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3802 * tm-news.h: Add CALL_DUMMY_*.
3804 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
3806 * config.gdb: In list_host, list_target, use ${i}, not $i.
3808 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3810 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
3812 * sparc-opcode.h: Change all store floating-point state register
3813 instructions to have the right match & lose fields.
3815 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3817 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
3819 config.gdb: If srcdir != ., create readline directory and
3820 copy a makefile into it.
3822 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
3823 consistency with POSIX.
3825 * breakpoint.c (bpstat_stop_status): Disable watchpoint
3826 when we exit its exp_valid_block.
3828 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
3830 * Makefile.dist: Bump version to 3.91.3.
3832 * Clean up handling of breakpoint commands (somewhat).
3833 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3835 inferior.h: Add breakpoint_proceeded to inferior status struct
3836 and globals; save it and restore it.
3837 (clear_breakpoint_commands): Cleanup, remove old #define.
3839 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3840 (save_inferior_status, restore_inferior_status): handle it also.
3841 (proceed): Remove earlier code that set breakpoint_proceeded.
3842 It is now set only in clear_proceed_status.
3843 (clear_proceed_status): Cleanup, use bpstat_clear rather
3844 than clear_breakpoint_commands. No callers need the stop_bpstat
3845 between clear_proceed_status and proceed.
3847 infcmd.c: Add breakpoint_proceeded definition and comment.
3848 (cont_command, jump_command, signal_command): Move call to
3849 clear_proceed_status right next to call to proceed.
3851 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3852 caller's argument while running down the chain of breakpoints.
3853 Use new variable "breakpoint_proceeded" to determine when
3854 a command that it executes moves the inferior past the
3856 (bpstat_clear): Handle NULL argument.
3857 (bpstat_clear_actions): Avoid useless call to
3858 breakpoint_auto_delete.
3859 (delete_breakpoint): Clean up bpstat's that are pointing to
3860 the deleted breakpoint from the stop_bpstat chain.
3861 (breakpoint_auto_delete): Simplify.
3863 * Clean up handling of EOF, error on stdin, etc. This was
3864 prompted by a network problem that caused gdb to go into an
3865 infinite loop filling up its malloc'd memory.
3867 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
3868 not clear_breakpoints_commands, which is now gone.
3869 (main): If command_loop returns (e.g. from EOF on stdin), do
3870 a quit_command (looping back to command_loop if quit_command
3871 doesn't really quit).
3872 (command_loop): check result from command_line_input and
3873 exit if it returns NULL, rather than passing the NULL to
3875 (gdb_readline): Free malloc'd result space before returning
3878 * utils.c (query): Handle C-d to mean "yes", just as if the
3879 input was not a terminal. Also avoid infinite loop if EOF
3880 occurs in mid-input-line before newline. This allows
3881 query to be used at EOF on stdin with reasonable results.
3883 * infrun.c (proceed): Set breakpoint_proceeded.
3885 * values.c (value_as_long): Avoid infinite recursion for enums.
3886 (_initialize_values): Fix typo in help msg (kingdon).
3888 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
3889 RL_LIB for linking. This allows -lreadline for linking
3890 and nothing for dependencies, once readline is a real library.
3892 * config.gdb: Jim Kingdon: give useful error message if the
3893 host or target type is not recognized.
3895 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
3896 it just defines it. Dumb, but deal with it.
3898 * Jim Kingdon suggests:
3899 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
3901 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
3903 * Makefile.dist (VERSION): Bump version # to 3.91.2.
3905 * Clean up Bothner's changes.
3907 * blockframe.c (clear_pc_function_cache): New function.
3908 * blockframe.c: remake cache_pc_function_* static.
3909 * dbxread.c (symbol_file_command): remove references to
3910 cache_pc_function_* variables.
3911 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
3912 * printcmd.c: Avoid kludging a global variable (addressprint)
3913 to avoid printing the address of a string twice. Instead,
3914 pass the format letter 's' down low enough that it can be seen
3915 to avoid this problem.
3916 (print_formatted): Pass format arg to value_print.
3917 (restore_addressprint): Remove function.
3918 (do_examine): Avoid hacking addressprint, cleanups and such.
3919 (print_frame_args): Add a comment to a Bothner change.
3920 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
3921 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
3922 to wipe out the values cached in blockframe.c.
3923 * symtab.c (find_method): Add comment saying how big you must
3924 allocate to be "big enough". Per being terse again.
3925 * valprint.c (val_print): Handle format letter "s" to print
3926 strings without addresses. Add comment to vtbl printing code
3927 which casts with wild abandon. Rearrange reference-printing
3929 @0xaddr: value (print w/addressprint)
3930 value (print w/~addressprint)
3931 @0xaddr (parameter lists w/addressprint)
3932 or nothing (parameter lists w/o addressprint)
3934 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
3936 * Merge more changes from Per Bothner:
3938 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
3939 annoying) that I tried to improve it. Here are my suggestions.
3941 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
3944 Do automatic de-reference when taking the address of a reference.
3946 Don't deref_ref when printing parameter lists.
3948 More attempts at treating refernences properly.
3950 In val_print, if deref_ref==0, don't print dangling " = ".
3952 Add COERCE_REF macro, which de-references an REF.
3954 * Merge changes from Per Bothner:
3956 * Fixed (Sony news)-specific configuration problems.
3957 * Fixed other problems with using vanilla pcc and libc (enum problems;
3958 assumption that vsprintf exists).
3959 * Some major speed-ups (finc_pc_partial_function now caches a match;
3960 parsing avoids duplicate symbol_lookup calls).
3961 * Changed handling of baseclasses (no longer use baseclasses field
3962 of struct type, use the first n_baseclasses fields instead).
3963 * Various minor changes/fixes, most C++-related.
3966 Cache the most previous match from find_pc_partial_function.
3967 (Save both low and high ends of matching function's pc range.)
3968 This speeds up the loop of infrun.c:wait_for_inferior quite
3969 a bit, and makes step/next commands much zippier.
3971 Added an enum->int cast (otherwise, some compilers barf).
3973 No longer set baseclass offset to 0, since multiple
3974 inheritance now mostly works.
3975 Added a number of casts, to shut up compiler warnings
3976 (after stabs where made enums, not ints).
3977 When discarding a symbol table (in symbol_file_command),
3978 must clear the cache introduced in blockframe.c.
3979 Don't convert $vtbl_ptr_type to vtbl any more.
3980 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
3981 Mask off sign bit emitted by g++ for virtual table offset.
3982 Set voffset to -1 (not 1) for static member functions.
3984 Changed parsing/lexing of names to avoid doing symbol lookup twice
3985 (once when lexing to determine symbol class, once for real).
3986 Now only call symbol_lookup once. Fields of 'this' win especially big.
3988 Subpress printing addr twice in the case of 'x/s addr'.
3990 lookup_basetype_type is no longer used.
3991 Add find_methods as recursive helper function to decode_line_1.
3992 This allows multiple inheritance to work.
3993 Also, once one or more matches has been found, do not look in
3994 base-classes. (Baseclass methods would be overridden, anyway.)
3996 Removed baseclasses array in struct type.
3997 Instead of using baseclasses[i], use fields[i-1].
3998 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
3999 Changed sign convention of voffset (previous was inconsistent).
4001 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4003 Used to assume existence of vsprintf. Re-written to not need it
4004 if HAVE_VPRINTF is undefined.
4006 typecmp was too pessimistic. Made it less so.
4008 Don't print space after address.
4009 If vtable points to a misc symbol (with 0 offset), print it,
4010 since that indicates the actual class of the object.
4011 Changed ype_print_derivation_info to use new inheritance
4012 scheme (without baseclasses vector).
4014 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4015 Also, changes needed because TYPE_BASECLASSES were removed.
4017 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4019 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4022 If there is no path set, and the symbols don't indicate what directory
4023 a file was compiled in, look in the current directory. But either
4024 a path or a known compilation directory will prevent this.
4027 Three independent bug fixes:
4028 * Remove the #if 0 block that breaks some stuff.
4029 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4030 adapt gdb to either SunOS 4.0.* or 4.1.
4031 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4034 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4037 (type_print) Demangle the name being printed.
4038 (type_print_base) Handle botched demangling without coredump (tiemann).
4041 (check_stub_method): Document routine.
4042 (tiemann) fix bug for no-arg functions
4043 Avoid clobbering beyond end of malloc'd storage.
4044 Terminate the argument list properly.
4046 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4048 * Changes merged by John Gilmore:
4051 In breakpoint_1, use new print_address_symbolic instead
4052 of find_pc_partial_function. (This forces use of assembler-level
4053 addresses, and avoids misleading non-mangled source-level names.)
4055 Generalize ansi argument such that -1 means skip arglist totally.
4056 Removed global variable print_ansi_qualifiers (which made
4057 code non-reentrant), in favor of extra explicit arguments
4058 to internal routines.
4060 Add new helper function print_address_symbolic.
4061 Use find_pc_misc_function instead of find_pc_partial_function
4062 (since we want assembler-level symbols here).
4064 Print unknown function as just "f (...)", not "f (...) (...)".
4065 Use new fputs_demangled explicitly.
4067 Fixed a typing violation (problem: value.h cannot be imported
4068 without renaming many variable in this file).
4069 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4070 decode_line_1: Moved forward some never-reached code.
4071 Made decode_line_2 skip function prologues correctly.
4073 fputs_filtered should not demangle by default.
4074 Add new fputs_demangled to demangle on demand..
4076 Change value_struct_elt to use value_primitive_field (using recursive
4077 utility function search_struct_field). This allows foo.bar to work
4078 for multiple inheritance (so far only for data fields).
4079 Change check_field in the same way (recursive helper function
4080 to support multiple inheritance).
4081 (Note: there are more of these problems that I haven't fixed.
4082 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4083 value_of_this: 'this' symbol name is now just "this", note "$this".
4085 Don't print static members.
4086 Avoid printing "members of <type>" if there are none.
4087 Simplified type_print_derivation_info by merging duplicate code.
4088 Remove useless blank lines in type_print_base (ptype command).
4090 Added declaration of new routine value_primitive_field.
4092 Added value_primitive_field which is generalized version of
4093 value_field that can handle multiple inheritance (non-zero offsets etc).
4094 Re-implemented value_field to call value_primitive_field.
4096 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
4098 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4099 delete the whole environment. Karl Berry reported the bug.
4100 * source.c - fix openp to avoid //'s in filenames, which
4101 trigger an Emacs bug causing it to not be able to find files
4102 when running gdb in a window.
4103 * dbxread.c - zap the #if 0 that botches the add-file code.
4104 It seems to work a lot better without all the code commented out.
4106 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
4108 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
4111 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
4113 * Makefile - added a ${CFLAGS} to a couple of entries,
4114 added remote-sa.sparc.c
4115 * added remote.sa-sparc.c, a modification of remote.c
4116 which conducts a dialog directly with the SparcStation prom.
4117 * breakpoint.c, infrun.c, sparcdep.c added
4118 remote_insert_breakpoint(), and remote_remove_breakpoint()
4119 to breakpoint.c instead of directly writing breakpoint instructions.
4120 * sparcdep.c on remote_debugging,there is no need
4121 to remove signle step breakpoint instructions.
4122 * main.c added "-epoch" flag and "int epoch_interface" to main.c
4124 * printcmd.c - epoch interface sends lisp expressions to open up
4125 epoch windows on inspection.
4126 * valprint.c - added arrayprint, and addressprint and made adding
4127 format controls easier
4128 * wait.h added a couple of undef's because we were getting
4129 complaints about WSTOPSIG and WTERMSIG begin redefined.

4199 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
4200 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
4201 when printing the type.
4203 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)

4225 step_resume_break_address != NULL, even if another_trap.
4226 If trap_expected and we enter sigtramp, then set up a
4228 If trap_expected is set when we hit the step_resume_break,
