1 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3 Make writing to files work properly. (Fixes to BFD are also needed.)
5 * core.c (core_open): Open file ourselves, read or r/w, depending on
6 write_files. Use bfd_fdopenr.
7 * gdbcore.h (write_files): New variable.
8 * exec.c (write_files): Define variable, add set&show for it.
9 (exec_file_command): Use write_files to open for read or r/write.
11 Make shared library reading happen automatically. These changes
12 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
14 * inferior.h (stop_soon_quietly): Add to exported variables.
15 * infrun.c (child_create_inferior): call solib hook, if defined.
16 (child_attach): call solib hook, if defined.
17 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
18 (find_solib): Use lookup_misc_func rather than hand-rolled.
19 (symbol_add_stub): New stub for catch_errors.
20 (solib_add): Avoid output if !from_tty. Catch errors rather
21 than just calling symbol_file_add and bombing.
22 (solib_create_inferior_hook): Interface with the target process
23 to let it read and alloc shared libs, then figure out what it did.
25 * core.c (validate_files): Fix typo, soften warning.
26 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
28 * utils.c (fputs_demangled): Avoid duplicate printing if
29 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
31 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
32 (Fix from pierre@la.tce.com (Pierre Willard).)
34 * main.c (catch_errors): Change argument to a char * from an int,
35 since a char * can point to a struct full of glop, but an int
36 is not guaranteed to be able to hold a pointer.
37 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
38 breakpoint_re_set_one, breakpoint_re_set): Adapt.
39 * core.c (core_open, solib_add_stub): Adapt.
40 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
42 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
44 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
45 by adding .NOEXPORT target.
47 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
51 * Makefile.in (VERSION): Roll to 4.0.
52 (gdb.tar.Z): Make refcard.ps as well, for shipment.
54 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
56 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
59 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
62 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
64 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
65 reflect above name change
67 * WHATS.NEW: correct pointer to refcard.
69 * doc/gdb.texinfo: update New Features, Installing
71 * doc/gdbint.texinfo: add short description of configure +template
73 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
75 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
77 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
79 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
80 tar file, add dependencies for referenced doc files.
82 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
84 * coffread.c, symfile.c, stack.c: saberized.
86 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
88 * doc/refcard.tex: permuted Essential Commands sec
90 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
92 set/show symbol-reloading
93 default set complaints 0
95 RET-repeat disabled after prompted long displays
96 processID (attach) interpretation of 2nd GDB cmdline arg
98 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
100 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
101 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
102 breakpoint.c, main.c: lint.
104 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
106 Install new configuration scheme for GDB and friends.
108 * config.sub: Translate ordinary names to three-part names.
109 * configure: Use three-part names internally.
110 * configure.in: Translate three-part names to filenames.
112 * README, WHATS.NEW: Update for gdb-4.0.
113 * Makefile.in: Roll VERSION to 3.99.
115 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
117 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
118 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
119 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
120 to single structures rather than arrays; when passing
121 their address, use &. This avoids trouble with bdead compilers.
122 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
123 instead. This avoids portability headaches.
124 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
126 * source.c (open_source_file): Avoid ANSI const bdeath by
127 skipping declaration and then casting result value.
128 * tm-hp300bsd.h: Clarify comment.
129 * utils.c (strstr): Result is const char *; ANSI bdeath.
130 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
131 since system include file defines it differently from "defs.h",
132 though the two are equivalent for our purposes.
133 * tconfig/hp300bsd: Add m68k-tdep.o.
135 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
137 * tconfig/sun*4: Remove warnings about system assembler.
139 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
141 * mcheck.c: Avoid warning about undeclared abort fn.
142 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
143 it causes recursive calls to error() when used in cleanups.
144 To do so requires that we make it a function, so we do.
145 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
146 * utils.c (do_cleanups): Remove the current cleanup from the
147 chain *before* calling it, in case error() is called from it.
148 The result won't be pretty, but won't be an infinite loop either.
150 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
152 * dbxread.c (read_struct_type): Grok anon structs for C++.
153 (vb_name, vptr_name): Null terminate these strings.
155 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
157 Minor bug fixes from BSD Net2 gdb:
159 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
160 returns 0, there is no previous frame.
161 * breakpoint.c (commands_command): If !from_tty, don't call
162 input_from_terminal_p().
163 * dbxread.c (record_misc_function): Speed up slightly.
164 (compare_psymbols): Ditto.
165 * infcmd.c (do_registers_info): Take a second argument to
166 determine whether to print float registers. "info registers"
167 does not do so anymore. "info all-registers" does, now.
168 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
170 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
171 * inflow.c (initialize_inflow): Set tflags_ours correctly.
175 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
176 executing_breakpoint_commands if we are interrupted by error.
177 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
178 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
179 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
180 catch_errors() so we can setup the frame regardless of whether
181 the shared libs work.
182 * ieee-float.c (double_to_ieee_extended): Get exponent from
183 right place in little-endian systems. From John Carey.
185 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
187 * main.c: Remove unused terminating_signals and catch_termination().
188 (long_options): Terminate with a zero element.
189 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
190 (gdb_readline): Make call-compatible with readline.
191 (init_signals): Improve comments re vfork vs. signal.
193 * utils.c (prompt_for_continue): Use new gdb_readline().
194 If we prompt for continuation, we don't let CR repeat the previous
195 command, once we get back to a prompt. It's too easy to keep
196 hitting CR, expecting "--more--" prompts, and have some long
197 command start repeating on you.
199 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
201 * blockframe.c (frameless_look_for_prologue): Speed up by
202 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
203 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
204 Define two variants, one faster.
205 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
206 and return zero, rather than giving an error.
207 (setup_arbitrary_frame): Initialize the PC in the new frame.
208 (skip_prologue): Add a second arg saying whether we're just
209 checking for a frameless function or not.
211 * core.c (core_open, core_close, core_xfer_memory): Move
212 section table pointers and bfd* into the target_ops.
213 (core_open): Allow errors in shared lib reading, etc.
214 (core_files_info): Describe shared library sections.
216 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
217 exec_files_info, set_section_command): Move section table
218 pointers and bfd* into the target_ops.
219 (add_to_section_table): Add BFD to section table.
221 * target.c (target_xfer_memory, target_info): Pass target to
222 xfer_memory and target_info functions.
225 * gdbcore.h: Move struct section_table.
226 * target.h: New home of struct section_table.
228 * solib.c (solib_add): New argument is the target_ops whose
229 section list is to be added to, if any. Reallocate the
230 sections in that target to add any that come from shared libs.
231 (throughout) so_sections renamed to sections.
232 (solib_xfer_memory): Deleted.
233 * tm-sunos.h (SOLIB_ADD): Add target argument.
234 (SOLIB_XFER_MEMORY): Delete.
236 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
237 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
238 from target_ops. It's the same on all targets. Add two section
239 pointers to target_ops.
241 * stack.c (find_relative_frame): Dump ancient algorithm for
242 "down", just use handy "next" pointers.
243 (frame_command): Don't error if there is no stack; let user
246 * inflow.c (new_tty_prefork, new_tty): New prefork routine
247 modifies static state in the parent process; new_tty itself
248 runs in the child and modifies the child's file descriptors
249 to match the saved static state.
250 * infrun.c (child_create_inferior): Call new_tty_prefork,
253 * infptrace.c (child_xfer_memory): Add ignored target arg.
254 * remote-eb.c (eb_xfer_inferior_memory): ''
255 * remote-nindy.c (nindy_xfer_inferior_memory): ''
256 * remote-vx.c (vx_xfer_memory): ''
257 * remote.c (remote_xfer_memory): ''. Rename from
258 remote_xfer_inferior_memory.
260 * main.c (main): Only try to attach "corefile" argument if
261 it starts with a digit.
263 * symfile.c (symbol_reloading): New "set/show" variable.
264 (symbol_file_add): Shorten message about symbol reading.
265 (add_symbol_file_command): Merge with add_syms_addr_command,
266 since this should work on all targets now.
267 (stop_whining): Default to zero, to shut up complaints
268 about bad symbol tables on many systems.
269 (free_named_symtabs): Just exit unless symbol_reloading.
271 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
272 and add comment explaining shared library screw.
274 * source.c: #if defined => #ifdef.
276 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
278 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
280 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
282 * doc/rdl-apps.texinfo: provide default readline-appendix finder
283 (doc/Makefile knows how to make one for local config)
285 * Makefile.in: use doc/Makefile for doc targets
287 * doc/Makefile: GDB documentation now has its own Makefile
288 doc/refcard.tex: renamed from "gdbrc.tex"
289 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
290 doc/gdbint.texinfo: add markup in "Cleanups" chapter
293 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
295 * values.c (baseclass_addr): When reading target memory, use the
296 length of the basetype, not the upper type. We've only malloc'd
297 enough space for the basetype, leading to errors in free().
299 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
300 ends up as a function specially, since we know the actual type of
301 the pointed-to address. This (somewhat) fixes display of
302 expressions that include misc_function_vector names. Try `cond 1
303 !strcmp("a","b")' then `i b'.
305 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
306 The child can be proceeded from inside wait_for_inferior in
307 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
308 getting skipped in that case.
310 * expprint.c (print_subexp): Use filtered output, since the
311 subroutines we call use it, otherwise the output is horribly
312 mangled, since output of wrappable stuff comes out late.
314 * Makefile.in: Bump VERSION to 3.98.1
316 * infrun.c (child_create_process): Use execlp to find the
317 shell to exec our target program. This requires some fiddling
318 with `environ' since there is no execlpe().
320 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
322 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
323 Minor rearrangement of refcard permits two new make targets--
324 gdbrc.dvi DVI output for refcard, using CM fonts
325 gdbrc.ps PostScript refcard, using PS fonts
327 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
331 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
332 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
334 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
336 * doc/gdb.texinfo: last changes for release.
337 Minor typo and formatting fixes; incorporated most fixes remaining from
338 filed mail commenting on earlier drafts.
340 Added warnings: pipes don't work in run command;
341 conditions are converse of assertions;
342 step over fn without debug info goes to next fn;
343 vars may have "wrong" values near fn entrance, exit
345 Added example from Kingston on printing repeated nonadjacent values
347 Added explicit mention that in Emacs gdb mode C-c and C-z are like
348 shell mode for signals
350 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
351 doesn't sound so much like its parent "Stopping and Continuing"; also
352 moved entries on continue to top of section, so they don't get lost.
354 Improved installation directions in appendix, added manual formatting
357 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
359 * configure.in: Remove xm.h and tm.h even if we aren't linking
360 new ones, so "./configure sun4; ./configure none" does the right
361 thing. Assume that alldeps.mak and depend are already built in
362 srcdir, and avoid running "make" (particularly "make depend",
363 which involves "gcc") from inside configure. Build Makefile
364 directly rather than building Makefile.conf first.
365 * configure: Regenerate with above changes.
366 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
367 to 3.98. Revise gdb.tar.Z procedure to produce a file
368 called gdb-$(VERSION).tar.Z but which unpacks into a
369 directory called "gdb". Move non-source files out of
370 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
371 (depend): Don't try to do "gcc expread.y".
372 (expread.o): Update dependencies by hand.
374 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
377 Fixed a variety of small typos that prevented info from formatting
378 cleanly; altered too-long heading for GPL Appendix, as discussed
379 w/RMS; Changed date on cover to July 91.
381 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
384 (1) Applied some fixes due to comments from Larry Breed (easier ones
386 (2) Eliminated use of @footnote---had my doubts about it anyways, and
387 it's broken in latest texinfo
388 (3) Introduced *some* use of [] for optional arguments, where
389 explanation is not simpler by listing cmd w arg and cmd w/out arg
390 separately. Still not using @deffn.
391 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
392 couple of headings are too long. Need patches to texinfo or revision
395 * Partial update to README (which still needs work for this
396 release!): (1) use of configure corrected for new script,
397 (2) "make gdb.dvi" and "make gdb.info" mentioned.
399 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
401 * symtab.c (lookup_symbol): Don't complain right off about
402 no debug symbols; use the misc function vector first.
403 (list_symbols): Use misc function vector to find symbols
404 that don't have debug info, and print them.
405 (find_pc_symtab): Temporarily avoid fatal() when psymtab
406 PC range doesn't match symtab PC range, as it does on the
407 MIPS because our symtab reading isn't perfect.
409 * dbxread.c (dbx_symfile_read): Make warning about
410 "no debug symbols" slightly nicer.
412 * source.c (select_source_symtab): If "main" symbol exists,
413 but decode_line_spec can't find line info, don't just return
414 a zero; try other source symtabs or give an error.
416 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
417 their low addresses first, then rip through fixing high addrs.
419 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
421 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
423 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
425 * Minor, mostly mechanical, cleanup of doc subdir for clean
426 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
427 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
429 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
431 Mostly MIPS and general symbol-reading fixups.
433 * doc/gdbint.texinfo: Add documentation on symbol-reading
436 * mipsread.c: Remove kludges around #include "ecoff.h".
437 Remove redefinitions of a_magic, etc, no longer used.
438 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
439 Fix global overview comments to match symfile.c protocol.
440 (mipscoff_new_init): Eliminate cur_hdr if we have one.
441 (mipscoff_symfile_read): Eliminate unused code. Avoid
442 sorting all the symtabs, when all we have read here is psymtabs.
443 The symtabs are sorted as they are created anyway. Tell
444 condense_misc_bunches whether we're mainline.
445 (psymtab_to_symtab_1): Pass filename when recursing, to make
446 stack trace more informative.
447 (parse_partial_symbols): Assume cur_hdr as argument.
448 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
449 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
450 the TYPE_NAME of char *, since that's done in symfile.c.
451 (free_numargs, parse_symbol, add_symbol, add_block,
452 shrink_linetable): Declare these fns void.
453 (upgrade_type): Convert tree of if's to switch. Clean up
454 bogus "off == 0" handling with a complaint. Avoid setting
455 field bitpos and bitsize of array with lower and upper bounds.
456 Check specified bitsize of elements against their actual type's
457 bitsize, and complain if different. Complain about unknown
459 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
460 (psymtab_to_symtab_1): Print names of subsidiary files that
461 are being read in. FIXME, we read far too many files. This code
462 is not the problem, the problem is in parse_fdr where the psymtabs
464 (cross_ref): Result should indicate that we used one aux entry
465 normally, or two if we encountered a "next" entry. This used
466 to leave the caller pointing at the wrong aux entry.
467 (add_symbol): If overflowed cur_block, reallocate it larger,
468 chase all pointers to it, and complain(), rather than clobber memory.
469 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
470 (new_field): Only allocate one field initially, not two.
471 Pull ++ out of macro argument. Simplify.
472 (_initialize_mipsread): Avoid initialization of importd
473 global_psymbols and static_psymbols.
475 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
476 to properly set pst->symtab; avoid searching for it.
477 (symfile_fns): Improve comments, add a FIXME.
478 * dbxread.c: Update comments to reflect symfile protocol.
479 (read_ofile_symtab, end_symtab): Return the symtab.
480 (psymtab_to_symtab_1): Set pst->symtab.
482 * coffread.c (coff_symfile_read): tell condense_misc_bunches
483 whether we're mainline.
485 * symfile.h (sym_fns): Remove unused sym_discard member.
486 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
488 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
489 the environment variable is not.
490 * infcmd.c (finish_command): Use filtered printfs.
491 * cplus-dem.c: Add struct tags to a few unnamed structs.
492 * valops.c (value_coerce_array): Improve comments.
493 * valprint.c (type_print_varspec_suffix): Print array size only
494 if greater than zero.
495 * m88k-tdep.c: Shift some lines left by one space, that had
496 apparently been trashed at some point.
497 * TODO: More things to do, a few got done.
499 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
501 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
502 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
504 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
505 * expread.y, findvar.c, symmisc.c: Ditto.
506 * printcmd.c (address_info): Update printed forms of LOC_
507 symbols. Elim LOC_EXTERNAL.
508 (print_frame_args): Keep track of param stack offsets before
509 re-looking up to find the local register param is kept in.
511 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
512 Further integration of mipsread into gdb. Eliminate unused
513 routines, duplicate declarations. Handle static symbols in
514 psymtabs as well as external symbols. When reading symtabs,
515 insert symbols into the correct block (global, static, or a local
517 (read_mips_symtab, parse_partial_symbols): Don't pass useless
519 (mipscoff_symfile_read): Don't call select_source_symtab.
520 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
521 rather than SYMBOL_VALUE.
522 (parse_external): Comment clobbering of top_stack.
523 (parse_partial_symbols): Update comments. Allocate and parse
524 static symbols as well as external symbols. FIXME, enum values
525 are not handled in this pass, but should be. Inline new_psymbol.
526 Use SYMBOL_VALUE_ADDRESS.
527 (psymtab_to_symtab_1): Read symbols into global static block
528 by default (until enter some function's local block context).
529 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
530 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
532 * source.c (select_source_symtab): Select a source symtab
533 from either the symtabs or, failing that, the psymtabs.
534 (list_command): Update error message.
535 (forward_search_command, reverse_search_command): Use getc, not
536 fgetc, for speed. FIXME, add comment about buffers that die if
537 overrun by long line.
539 * values.c (unpack_field_as_long, modify_field): Avoid shifting
540 by an entire word, which is not portable, if we have a 32-bit
541 field. (Code in dbxread.c already turns such bitfields, if
542 aligned, into ordinary ints, but fixing this will help for other
543 symbol formats and for future changes.)
544 * core.c (core_open): Handle ANSI const brain death.
545 * utils.c (vprintf): Fix varargs typo.
547 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
549 * findvar.c (find_var_value): Handle &function better.
550 * TODO: Document work needed on &fn and &array.
551 * printcmd.c (print_address_symbolic): New arg is the prefix
552 to print if a name is printed.
553 (print_address_demangle): Honor "set print address" now.
554 Use new arg above to improve spacing of output.
555 * valprint.c (val_print): When printing function pointers,
556 print symbolic form too.
557 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
559 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
561 * core.c (memory_error): Reword error msg to mislead less.
563 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
565 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
566 parse_partial_symbols): Use newer BFD internals (external_filehdr
567 and external_aouthdr), byte-swap the fields that we care about
568 before using them, and make the file header data local to
569 read_the_mips_symtab rather than global.
571 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
573 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
574 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
576 * main.c (command_line_input): Flush stdout and stderr
577 before every call to readline. This reportedly fixes a bug
578 that comes up in Sys V running emacs-gdb and/or xxgdb,
579 when stdin/out are pipes or sockets.
581 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
583 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
584 Avoid declaring Makefile dependencies, because GNU Make stupidly
585 tries to update it if we do.
587 * coffread.c: Revise for minor changes to bfd internal coff
590 * configure: If -template= is given a relative path, make it
591 absolute before recurring in subdirectories.
593 * configure, configure.in, Makefile.in: Install "configure" script
594 as replacement for config.gdb.
595 * config.gdb, Makefile.dist, Makefile.sdir: Remove
596 * README: Update for configure, mostly. FIXME.
598 * Add dec3100 as equivalent to littlemips. Indicate in all host &
599 target config files that they are for the host. When the lines
600 get copied into the Makefile, this makes it more obvious what's
603 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
605 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
606 tabs, which end up in the disassembler output inadvertently.
608 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
610 Make it compile cleanly in an ANSI GCC2 environment.
612 * blockframe.c: <stdio.h>
613 * cplus-dem.c: free takes a void *, ifdef __STDC__
614 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
616 * defs.h (alloca): Avoid doing anything if alloca already def'd.
617 * stddef.h, stdlib.h: Remove these files.
618 * symtab.c: Avoid declaring qsort, close.
619 * symfile.c: Avoid declaring close.
620 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
621 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
623 Assorted other changes.
624 * dbxread.c: include "libaout.h", not "liba.out.h".
625 * printcmd.c (print_frame_args): Set recurse properly for
626 indentation of struct and array parameters.
627 * valops.c (value_cast): Allow cast to void.
628 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
629 single_step() in a target-independent fashion.
630 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
631 set up to be ready to continue. This makes us target independent.
632 * infptrace.c (child_resume): Remove call to single_step; now
633 can single step a SPARC target of any kind.
635 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
637 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
638 docn into separate sections---basically chapters, plus two loose
639 pieces that can be configured to go in different places. This
640 allows GNU m4 to preprocess the manual without coredumping.
642 * Makefile.dist: tell TeX where to find texinfo.
644 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
646 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
647 the new target "rdl-apps.texinfo" which captures the Makefile
648 variable that records where to find the Readline libraries.
650 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
652 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
653 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
654 * defs.h (const, volatile): Only define if not already defined.
655 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
657 * README: Update for release 3.95.
658 * config.gdb: Don't create readline dir in subdir builds.
659 * main.c: Include with "..." form for non-system include files,
660 so "gcc -MM" for "make depend" works.
661 Include readline files with "...h" rather than <readline/...h>.
662 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
664 * coffread.c: Undo minor damage done by Rich Pixley. Use
665 different internal and external representations of COFF
666 data structures. Use new BFD routines for swapping them in and
668 * symfile.c (free_named_symtabs): Avoid freeing file names that
669 are null or empty. Old i960 tools seem to produce files that
670 claim to have empty names, causing each successive file read
671 to blow away the previous one.
672 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
673 Move deferred_stores to top of file, but don't separate its
674 #define's from its variable. Add commentary.
675 * Makefile.dist: Fix Rich damage; undo "configure" changes in
676 favor of keeping the (working) config.gdb. Move readline
679 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
681 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
683 * infptrace.c (fetch_registers): no result, since now void.
684 * tconfig/news: target depends on m68k-tdep too.
686 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
688 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
691 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
692 applied various small fixes due to or inspired by RMS comments
694 * doc/gdb.texinfo: finished using all RMS comments, save those for
695 appendices on readline and cmd history (which are in other source
698 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
700 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
701 chapter 9; (2) documented 'break' command's menu mode for
702 overloaded names, in response to hgs problem report C++ p-31
704 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
706 * doc/gdb.texinfo: (1) better introductory example; (2) more
707 consistent use of @code, @samp, @file, @kbd throughout; small
708 cleanups to first three nodes; (3) new "Contributors" node;
709 (4) Appendix, Renamed Commands; (5) divert specialized startup
710 instructions to "Targets" chapter for generic manuals, while
711 leaving them up front for manuals specific to specialized
712 environments; (6) apply fixes from RMS comments through chapter 4.
714 * pretex.m4: modify explanatory text slightly (and redefine
715 "regexp") to keep GNU m4 from complaining. (It still crashes
716 later, but one step at a time...)
718 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
720 * readline/readline.c (update_line): Avoid dereferencing a pointer
721 before comparing it to its bounds. Saber caught this.
722 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
723 and only set PC if tgetstr returned non-null. Saber caught this.
725 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
727 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
728 stuff for config manual) here where it counts; updated
729 to use new subdir structure (gdb/doc/).
731 * Makefile: generated from above via
735 * gdbint.texinfo: added instructions on generating gdb.info* files
736 locally for release. These are ordinary info
737 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
738 Makefile)---but due to use of texinfo 2, can't count on makeinfo
739 to generate these, so we distribute them already formatted.
741 * gdb.texinfo: included full Info node and menu crud (as generated
742 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
744 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
745 put in comments-for-future gdb.info target (one day makeinfo will
748 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
750 * gdb.texinfo: Updated to include new or old undocumented
751 commands, at least the following (perhaps some others I forgot to
752 record): info f, info float, info path, info program, info s, info
753 set, info source, info terminal, info types, info user, set/show
755 Also covered all recent GDB command renames for v4.
757 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
759 * mipsread.c: Rather than keeping count of how many symtabs
760 and psymtabs we have, for sorting purposes, count them when
761 we need to sort. This fixes bug in rereading of symbol tables.
763 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
765 * infcmd.c: renamed "info path" to "show paths"
766 * gdbrc.tex: documented above.

776 Fix up "saber_gdb" to work again.
777 * saber.suppress: Update.
779 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
780 symtab.h, target.c, target.h: Lint.
781 * core.c: setup and select frame after reading shared libs,
782 else reading shared libs will clobber them. Lint.
783 * utils.c (error): Force out any buffered wrap text.
785 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
787 * remote.c: Remove decls of memory_insert_breakpoint
788 and memory_remove_breakpoint, no longer used. (Suggestion of
791 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
792 to make it easier to interface to "configure"'d libraries.
794 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
796 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
797 aliases for set/show print.
799 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

856 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
858 * signame.c: Cast const char* to char* when assigning to sys_siglist.
860 * utils.c (strsave): Make arg const char* not char*.

867 * tm-88k.h (EXTRACT_RETURN_VALUE): Use char * not void *.
869 * findvar.c (read_var_value, case LOC_CONST_BYTES): Put the address
870 in a char *, not a CORE_ADDR. Use SYMBOL_VALUE_BYTES.

885 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
886 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
887 (This still doesn't seem to make MIPS bkpts work.)

889 (symbol_file_command, add_file_command): Remove, obsol.
890 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".

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

929 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.
931 * tm-sparc.h: Remove GET_RWINDOW_REG.
932 (FRAME_CHAIN): Call sparc_frame_chain.
933 sparc-tdep.c (sparc_frame_chain): New function.
934 tm-sparc.h (EXTRACT_STRUCT_VALUE_ADDRESS): call
935 sparc_extract_struct_value_address (added to sparc-tdep.c).
937 * xm-sun386.h: Don't define SET_STACK_LIMIT_HUGE.
939 Tue Apr 30 13:13:33 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
941 * valprint.c (type_print_base): If the type being printed is a

1402 (set_section_command): New command ("section xxx yyy" -- should
1403 be renamed to "set section xxx yyy" FIXME) which sets the

1417 * i386-pinsn.c: Move #includes to top, remove useless ones.
1418 * i386-tdep.c: Don't bother including <.../reg.h> since we

1435 current frame in the core file, if we have one.

1456 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1457 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1460 * command.c (user_info_1, user_info): New command for listing
1461 the user-defined commands.
1463 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1465 * dbxread.c (really_free_pendings): Clear file_symbols
1466 and global_symbols after freeing them; otherwise, running
1467 this function twice (if it appears twice on the cleanup
1468 chain), we try to free things twice.
1470 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1471 based on text_addr (the address of text in core), not on addr (the
1472 offset between text in the .o file and in core). This change
1473 is from Peter Schauer.
1475 * main.c: Define ALL_CLEANUPS as a cast of zero.
1476 (return_to_top_level): Use it.
1477 (main): Do all cleanups after each command run as part
1478 of the gdb startup sequence. Also do all cleanups before
1479 entering the command loop, and every time we exit the command
1480 loop and reenter. Before, the cleanups from the startup sequence
1481 were being left undone until the first error!
1482 (command_loop): Rename do_nothing cleanup to command_loop_marker
1483 so we can see it easily when examining the cleanup chain.
1484 (init_signals): Add another do_nothing for signal handling.
1485 (quit_command): Only try to kill target if it has execution.
1486 Problems in the target stack got us into a state where
1487 inferior_pid was nonzero but none of the targets had execution.
1488 In this state you couldn't exit gdb.
1490 * dbxread.c: Two changes from Peter Schauer.
1491 (echo_command): Fflush output after an echo command.
1492 (show_history): Pass all args to cmd_show_list.
1494 * utils.c (init_malloc): Call mtrace to turn on tracing
1495 if the environment variable MALLOC_TRACE is set to a file name.
1496 * mtrace.c: Add source file which provides a log of every malloc,
1497 free, and realloc to a trace file.
1498 * mtrace.awk: Add source file which analyzes the trace file.
1499 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1500 (VERSION): Roll to 3.94.3.
1502 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1503 (check_duplicates): Don't bother with watchpoints.
1504 (set_raw_breakpoint): Comment about danger of this routine.
1505 (watch_command): Parse and eval all args before calling
1508 * solib.c (find_solib): Avoid error in referencing memory to
1509 see if any more shared libraries have been added. This is
1510 particularly useful if the target has terminated. Bug reported
1513 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1514 in bringing up 3.94.2 on the Sun-3.
1516 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1517 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1518 expression (in scope) before reenabling watchpoint.
1519 * signame.c (init_sigs): Add missing declaration of i, fix
1520 sys_siglist declaration.
1521 * source.c (list_command): Fixed range computation to use
1523 * stack.c (backtrace_command): Do not allow command if target has
1524 no stack, print informative error message.
1525 * target.c (target_command): Do not write into command line
1526 because this fails if the target command is used in a user defined
1527 command. [This change was enhanced by gnu to support any-
1528 unique-prefix matching on target names.]
1529 * valops.c (value_struct_elt): Avoid infinite loop on an
1530 erroneous attempt to print the member of function (try p main.p).
1532 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1534 * expread.y (name_no_typename): Avoid reduce/reduce errors
1535 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1536 Since the GDB parser really doesn't use name_no_typename in a
1537 name-only context, the parser can't tell the diff between
1538 names and numbers here. Avoid allowing a name_no_typename
1539 to be a NAME_OR_*INT to resolve the conflict.
1541 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1543 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1545 * valprint.c (val_print_fields): bitfield printing didn't handle
1546 byte order. Indirect through a few more fns to cope.
1548 * values.c (modify_field): also cope with byte order.
1550 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1552 Cleanup for release 3.94.2:
1554 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1555 include files. Roll version to 3.94.2.
1557 * coffread.c (init_stringtab): Read length into unsigned char
1558 array before swapping; don't assume 32-bit longs.
1560 * target.c (target_info): Don't bother with get_sym_file, just use
1561 the symfile global variable.
1562 * symtab.h, symfile.c (get_sym_file): Delete it.
1564 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1565 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1566 (read_type): Replace one more error() with complain().
1568 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1570 * i960-tdep.c: Fix copyright attribution.
1572 * config.gdb: Quote all backquotes in doublequotes. You can
1573 quote me on that. BSD 4.4 shell found this one.
1575 * infptrace.c (throughout): The third argument to ptrace is an
1578 * infrun.c (wait_for_inferior): When program has terminated, we
1579 have to call target_terminal_ours before we pop that target off
1580 the stack (e.g. before a call to target_kill or
1581 target_mourn_inferior). This fixes problem where a program
1582 terminates, then GDB stops for (tty output) and you have to type
1583 "fg" to the shell to resume it. FIXME: This code for what to
1584 do after termination really should be in normal_stop instead.
1586 * gdbcore.h (read_memory_check): Change declaration; it changed
1589 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1590 4.4 prereleases, this avoids a bug in their sgtty compatability
1592 * remote.c: Use terminal.h rather than hand-rolling the same.
1594 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1595 * utils.c (strsave, strstr): Fix arg types.
1596 * valprint.c (val_print): lint
1598 MIPS symbol table support from Per Bothner:
1600 * symfile.c (symtab_fns): Remove initializer table that needs to
1601 be hacked for each new symbol file format supported.
1602 (add_symtab_fns): New function, chains symbol table
1603 handlers into the global list.
1604 (symfile_init): Search this list.
1605 * symfile.h: Add next pointer, declare add_symtab_fns.
1606 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1607 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1609 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1610 symbol *). Thus, we no longer need the hack to trash
1611 pst->filename. Good, since that hack confused code in symfile.c!
1613 (reorder_symtabs, destroy_all_symtabs): Removed static
1614 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1615 Instead, the latter now uses a temporary array (stack-allocated
1616 from an obstack, and then freed).
1618 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1619 haven't been set in the outermost stBlock of a procedure. This was
1620 a problem with f77 binaries on Ultrix 4.?.
1622 (new_symtab, new_symbol, new_type): Continue changing code to use
1623 obstacks more and otherwise conform to dbxread internal style.
1624 Made the free_code of symtabs be free_linetable (as in dbxread)
1625 instead of free_contents. This implies memory leaks when reading
1626 a new symbol table, until the conversion is finished. Did change
1627 (struct symbol) and (struct type) to be allocated on the
1628 symbol_obstack. Blocks and blockvectors are among the things
1631 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1632 tested much, but it solved one problem (reported by Meissner), and
1633 cleans up some other things. The problem happened when an
1634 included file contains actual code (functions) and not just
1635 definitions. The mips coff is a little inconvenient there, since
1636 it may cause a procedure to be mapped to the wrong psymtab.
1638 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1639 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1640 this will need work for the new core paradigm.
1642 Opcode patches from the net:
1644 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1645 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1646 missing altogether - they are added here. From Bruce Bauman.
1647 * mips-opcode.h: The low mask for C0 instructions was too small.
1648 From Garrett Lau. I modified the fix to check the entire 32-bit
1651 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1654 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1656 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1658 * dbxread.c (read_type): Pointer subtraction (value_sub in
1659 valarith.c) sometimes failed because the types of the
1660 pointers being subtracted were not identical.
1661 These differed because dbxread.c was allocating pointer types
1662 using dbx_alloc_type+smash_to_pointer_type instead of
1663 lookup_pointer_type. I failed to find a justification for the
1664 former, so I changed it to use the latter. Similarly, I
1665 replaced smash_to_function_type by lookup_function_type,
1666 and smash_to_reference_type by lookup_reference_type.
1668 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1669 _initialize_mipsread): corresponding changes.
1671 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1673 * source.c (mod_path): Do tilde_expand on each component of the path,
1674 rather than on the (list of) paths as a whole.
1675 (print_source_lines): Set first_line_listed in addition to
1676 current_source_symtab and current_source_line. If the source was
1677 not findable, after a "dir" command to fix the problem,
1678 a "list" would get the wrong lines.
1680 While I was there... (gnu):
1682 * dbxread.c (read_type): Change error to complaint.
1684 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1686 First attempt at detailed understanding of symbol table memory alloc.
1688 * dbxread.c (dbx_symfile_read): Free our string table if we
1689 aren't the mainline. Free the "info" struct since we're done with
1691 (init_psymbol_list): Free any previously allocated psymbol lists.
1692 (): FIXME: Should realloc-down the psymbol lists when done reading
1693 the main symbol file?
1695 * symmisc.c (free_symtab): Free fullname field too.
1697 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1698 (REGISTER_ADDR): Make result type unsigned int.
1700 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1701 define REGEX must also define REGEX1 (its dependency).
1703 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1705 * tconfig/i960: No longer works, points you at vxworks960 or
1708 * xgdb.c, XGDB-README: Remove file. Users can get the much
1710 * Makefile.dist: Remove all trace of xgdb.
1712 * breakpoint.c (breakpoint_1): Pass demangle arg to
1713 print_address_symbolic.
1714 (clear_breakpoints): Remove unused function.
1715 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1716 (breakpoint_re_set): Use catch_errors to do them all anyway.
1718 * gdb-int.texinfo (Host versus Target): Add section on what is
1719 a "host" feature versus what is a "target" feature.
1721 * infcmd.c (path_command, path_info): Handle the PATH variable
1722 (object search path) as conveniently as the source search path.
1723 * environ.c (set_in_environ): Set some vars in GDB's environment,
1724 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1725 * source.c (mod_path): New function, from guts of
1726 directory_command, modifies a path. Used by path_command.
1727 (directory_command): Call it.
1728 * defs.h (strsave): Declare.
1730 * utils.c (sevenbit_strings): Add new printing option.
1731 (printchar): Use it.
1732 (strsave): Provide this handy helper routine.
1733 (set_width_command): Rename set_screen_width_command.
1734 (_initialize_utils): "set screen-width" => "set width";
1735 "set screen-height" => "set height"; add sevenbit-strings.
1737 * infcmd.c (do_registers_info): Print floating point registers
1738 in raw hex as well as float format, regardless of whether it is
1739 a "virtual" convertible register.
1740 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1741 regs as a double, just in case it's being used that way.
1742 * values.c (unpack_long): Comment on array/function coercion.
1743 (unpack_double): Argument is in target byte order now. For
1744 integer arguments, just call unpack_long and float the result.
1745 * m68k-tdep.c: include defs.h for "const" handling.
1746 * remote-nindy.c: Use ieee-float stuff.
1747 (nindy_fetch_registers): Unpack double regs to host double, then
1749 (nindy_store_registers): Pack extendeds to host double, flip
1750 around by misusing unpack_double, send as target double.
1752 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1753 zero, as when stopped at the first instruction of a process.
1755 * blockframe.c: Fix filename in comment (param.h => tm.h).
1756 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1757 * tm-68k.h: Fix typos.
1759 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1761 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1763 * coredep.c (fetch_core_registers): Pass end-address of register
1764 section to register_addr as expected. Don't call supply_register
1765 if we'd just pass it garbage.
1767 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1769 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1771 * target.c (push_target, target_info): Cast enums to int for < or
1774 * stack.c (print_frame_info): Identify source file & line
1775 even if we can't print it.
1777 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1779 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1781 Clean up IEEE floating point support.
1783 * ieee-float.h: New file.
1784 * ieee-float.c: Write real routines to convert between host
1785 doubles and various target IEEE extendeds.
1786 * m68k-xdep.c: Eliminate assembler code for extended floats.
1787 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1788 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1789 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1790 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1791 double_to_ieee_extended.
1792 * i960-tdep.c: Define ext_format_i960.
1793 * m68k-tdep.c: Define ext_format_68881.
1794 * sparc-tdep.c: Define ext_format_sparc, though unused.
1795 * Makefile.dist (HFILES): Add ieee-float.h.
1796 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1799 Obsolete the "coffstrip" program in favor of using BFD's strip.
1801 * nindy-share/coffstrip.c: Remove file.
1802 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1803 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1804 * tconfig/nindy960: Remove reference to coffstrip.o.
1806 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1808 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1810 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1811 * dbxread.c: Remove static symfile_bfd.
1812 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1814 * inftarg.c (child_detach): Pop the child_ops vector if the
1815 detach is successful.
1816 * remote-nindy.c (nindy_create_inferior): Don't push a new
1817 nindy_ops since nindy uses the same one for execution and memory
1819 * core.c (core_ops): Use child_attach and child_create_inferior
1820 rather than default attach and create_inferior functions.
1822 Handle floating point registers in core files.
1824 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1825 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1826 This version untested since BFD doesn't yet support sun3 core
1828 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1829 conventions. Fix comments and style. This version has not
1830 been compiled yet, since we have no HP inhouse.
1831 * core.c (get_core_registers): Look for two sections, ".reg"
1832 and ".reg2", and pass both to fetch_core_registers sequentially.
1834 Revise directory path yet again.
1836 * source.c (forget_cached_source_info): Not static any more.
1837 (init_source_path): New default source path is "$cdir:$cwd".
1838 (dir_command): Handle variable arguments ($cdir, $cwd).
1839 (source_info): Print "Compilation directory" rather than
1840 "Originally compiled in" to remind people of $cdir.
1841 (openp): If the path contains $cwd, use current directory.
1842 (open_source_file): If compilation directory is known, replace
1843 first $cdir in path with the compilation directory.
1844 (print_source_lines): Even if we can't print the lines, set the
1845 current symtab and line for future commands like "info source" or
1846 "breakpoint". Also, error message now contains the file name,
1847 line number, and file access error message.
1848 (_initialize_source): Fix help text to describe changes.
1849 * main.c (cd_command): Forget cached source info when we chdir.
1850 * utils.c (strstr): Add simple implementation.
1852 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1854 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1855 Byte-swap COFF symbol tables if necessary when reading them in.
1856 Use complain() to replace error message in one spot. Needs
1857 corresponding change in bfd/coff-code.h to make some symbol
1858 swapping routines non-static.
1860 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1862 Merge changes from Eirik Fuller, for UTek.
1864 * defs.h (errno): Add declaration.
1865 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
1866 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1867 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1868 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
1869 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
1870 declarations of errno.
1872 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1874 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1875 <rpc/rpc.h> and <rpc/types.h>.
1877 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1879 * i960-tdep.c (examine_prologue): Add new argument limit,
1880 which stops the scan at the end of the prologue, or at the PC.
1881 This fixes a problem where it walks down into the code for the
1882 user's statements if that code looks like function prologues.
1883 Mark Fox and I have been bouncing this code back and forth, making
1884 small changes to it. Callers changed to match.
1886 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1888 Cleanup for gdb-3.94 release final:
1890 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1891 the .c files from vx-share and nindy-share, from the various
1892 macros, since they are not found via ALLDEPFILES.
1893 (SFILES): Add tm-i960.h.
1894 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1895 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1897 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1898 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
1900 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
1902 * am29k-tdep.c: Add contribution line.
1903 (examine_prologue): Cache information about function prologues in
1904 the misc-function-vector to avoid lots of references over the
1905 serial line while examining instructions.
1907 * core.c (core_close): New function made from cleanup_core.
1909 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1910 remote-vx.c, remote.c, target.c, target.h,
1911 Update target_ops vector to add attach, close, and load entries.
1912 Use add_syms_addr_command, not add_file_addr_command, for
1913 add_file. Break out close routine from existing code.
1915 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1916 they are in an obstack.
1917 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1919 (define_symbol): Add symbol type parameter; change callers;
1920 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1921 it to influence the symbol class on the i960.
1922 (define_symbol): Swap LOC_CONST's into target byte order.
1924 * exec.c (exec_close): New function.
1925 (exec_file_command): Call it.
1927 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1928 Fix byte order of frame pointer.
1929 (read_var_value): Result of 0 if var's value can't be found,
1930 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1931 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1932 (locate_var_value): Use read_var_value and use its lazy address
1933 as the location of the var's value. Lint.
1935 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1938 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1939 obsolete Intel versions in favor of vxgdb versions.
1940 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1941 code dealing with byte order of values, which Intel did in host byte
1942 order rather than gdb-4's target byte order.
1943 (i960_frame_chain_valid): Move to nindy-tdep.c.
1944 (examine_prologue, skip_prologue, frame_find_saved_regs,
1945 frame_args_address, leafproc_return, saved_pc_after_call,
1946 pop_frame): Add vxgdb versions from Mark Fox.
1947 (examine_prologue, frame_struct_result_address): Add code
1948 to deal with the saved value of G13 (struct return address
1950 (frame_args_address): Modify Mark's version to prefer the
1951 saved value over the current value in the topmost frame.
1952 Cache result in the frame info to avoid performance hair in
1954 (print_fault): Add gdb960 code for printing faults.
1955 (_initialize_i960): Actually call check_host.
1957 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1958 add stub routines. FIXME, these currently just return zero!
1960 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1961 (attach_command): Call target_attach, not target_open, now.
1963 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1964 (child_attach): Rename from child_open.
1965 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1966 don't confuse it with a zero step_resume_break_address.
1968 * inftarg.c (child_detach): Eliminate inferior_pid test.
1969 (child_files_info): Clean up message a bit.
1970 (child_ops): Use child_attach, not child_open, to attach.
1972 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1973 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1974 findvar.c to here, since it depends on the contents of the
1975 shadow_contents of breakpoints, but keep if #if 0 since it is
1978 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1981 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1982 (ptype_command, display_command): Eliminate have_inferior_p and
1983 have_core_file_p in favor of target_has_stack or
1984 target_has_execution.
1985 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1986 code for actually finding the values of arguments, though we still
1987 keep track of the maximum stack offset for use in printing unnamed
1988 arguments. Handle missing FRAME_ARGS_ADDRESS.
1990 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1991 (struct nindy_regs): Define registers passed to/from nindy.
1992 (nindy_fetch_registers, nindy_store-registers): Translate between
1993 nindy and GDB formats for the registers.
1994 (dcache_init): Statically allocate the cache, since it was being
1995 allocated by a malloc that was never freed anyway.
1996 (nindy_create_inferior): Error, not core dump, if no exec file.
1997 (nindy_before_main_loop): Use target_load, not target_add_file.
1999 * remote-vx.c (net_load): Specify large timeout for load
2000 requests. Allow user to break out with INTERRUPT.
2001 (net_break): Remove useless code, clean up. Change callers.
2002 (parse-args, skip_white_space, find_white_space): Clean up arg
2003 parsing to cope with quoted strings.
2004 (net_wait, net_quit): Never call error, just return status.
2005 (vx_read_register, vx_write_register): Cleanup status checking.
2006 #ifdef the code based on which CPU we are using (960 or 68k),
2007 FIXME, this should be completely general but it isn't yet.
2008 (vx_xfer_memory, vx_resume): Cleanup status checking.
2009 (vx_run_files_info): Improve message.
2010 (vx_load_command): Renamed from vx_add_file_command. Allow load
2012 (net_ptrace): Remove unused routine.
2013 (vx_wait): Adopt code from vxgdb960 to cope with broken
2014 connections to target machine and prompt to disconnect. Remove
2015 debug printouts. Map some EVENT_'s to SIGnals.
2016 (add_symbol_stub, vx_open): Print names of object files we found,
2017 and "ok" if we read their symbols OK. Clarify output in general.
2018 (vx_attach, vx_detach, vx_kill): Add these commands.
2019 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
2020 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
2021 "info files" output, and create_inferior, since we already have
2024 * stack.c (frame_info): Replace Frame_unknown with 0.
2025 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
2026 (return_command): Pop until the PC matches as well as the FP,
2027 so it works even if the FP is shared with another function,
2028 as in "frameless" or "leaf" procedures.
2030 * symfile.c (load_command): renamed from add_file_target_command.
2031 (add_syms_addr_command): renamed from add_file_addr_command.
2032 (add_syms_command): Stub to call target_add_syms.
2033 (_initialize_symfile): Change command names and descriptions,
2034 add-file => add-syms, and load from alias to its own command.
2036 * target.c (kill_or_be_killed, maybe_kill_then_attach,
2037 maybe_kill_then_create_inferior): Default for attempts to start
2038 a process, if one is already running, is to ask about killing
2039 it and retry if yes.
2040 (upstack_create_inferior): #if-0 it, strata obsolete it.
2041 (push_target, unpush_target, pop_target): to_close() a target
2042 before unstacking it.
2043 (target_info): Renamed from target_files_info.
2044 (_initialize_targets): Rename "i files" as "i target", accessible
2047 * target.h: Improve comments about the target_ vectored routines.
2049 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
2050 Convert commenting style to standard GNU style.
2051 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
2052 (SKIP_PROLOGUE): No longer a no-op.
2053 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
2054 (*_REGNUM): Sort register numbers.
2055 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
2056 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
2057 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
2058 are now 10 byte extendeds, not 8 byte doubles.
2059 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
2060 for nindy versus vxworks targets. FIXME, this should possibly go
2061 in the target vector.
2062 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
2063 frame_saved_regs and arg pointer with each frame.
2064 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
2065 (FRAME_ARGS_ADDRESS): Use cached result.
2066 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
2067 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
2068 (PRINT_RAMDON_SIGNAL): Call print_fault.
2069 (POP_FRAME): Now works.
2071 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
2072 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
2073 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
2074 (ADDITIONAL_OPTION_HANDLER): use target_load, not
2077 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
2078 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
2080 * valarith.c (value_subscripted_rvalue): Avoid handling
2081 floats and doubles specially; it gave alignment errors. Lint.
2083 * valops.c (value_of_variable, value_of_this): Error if unknown
2086 * valprint.c (print_floating): Bcopy rather than pointer-deref,
2087 to avoid alignment problems.
2088 (value_print): Handle unknown value address.
2089 (cplus_val_print): Two args are ignored; remove them. Change caller.
2090 (val_print): Use unpack_long rather than pointer-deref.
2093 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
2094 to avoid alignment problems.
2095 (value_being_returned): Error if return value unknown.
2096 (set_return_value): Add bogosity warning, FIXME. *
2098 * TODO: A woman's work is never done.
2100 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
2101 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
2102 Add ieee-float.o to OBS.
2103 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
2104 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
2105 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
2107 Changes to generalize the VxWorks RPC protocol slightly, to handle
2108 i960 as well as 68000.
2110 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
2111 * vx-share/reg.h: Produce i960 regs #ifdef I80960
2112 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
2113 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
2114 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
2115 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
2116 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
2117 so they will move in target byte order rather than network
2118 byte order (happens to be the same).
2120 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2122 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
2124 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2127 Add contribution lines to various files, showing where they
2130 * breakpoint.c (break_insn, check_break_insn_size,
2131 read_memory_nobpt): Remove to mem-break.c.
2133 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
2136 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
2137 entry has bad register number. This change is not
2138 tested in this release, FIXME.
2140 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
2143 * value.h: Force value's contents field to be aligned to hold
2144 at least a double or a long long (if supported). This avoids
2145 doing bcopy's in and out of the contents field.
2147 (step_1): Avoid coredump under obscure circumstances when we
2150 * symtab.h (misc_info): Add field to misc function vector for
2151 any kind of cached information the target code desires. AMD
2152 29000 uses this to avoid repeating examine_function_prologue's.
2154 * coffread.c: Lint. Remove static symfile, read_section_header.
2155 core.c (have_core_file_p): Lint: remove.
2156 expprint.c (print_subexp): Lint.
2157 infptrace.c, valops.c, valprint.c: lint.
2159 Roll in changes from vxgdb-5.0.1:
2161 * symtab.h: Comment byte order of each address class. Add
2162 LOC_LOCAL_ARG for frame-relative args (960).
2163 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
2164 symtab.c, symmisc.c: ditto.
2166 * infrun.c (init_wait_for_inferior): Clear stop_signal.
2168 * remote.c (remote_resume): Error if resume with a signal.
2170 * symfile.c (prim_record_misc_function): Clear misc_info.
2171 (fill_in_vptr_fieldno): Check stub type of arg.
2173 * valops.c (value_cast): Avoid looking up names of types whose
2174 name we don't know, to prevent coredump. Sun CC produces typedef
2175 rtx and the name of *rtx is zero...
2177 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2179 Roll in changes from final AMD 29000 port (Tiemann).
2181 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
2182 for ../include/a.out.encap.h. This might not work now that BFD
2183 is separately compiled. Instead, BFD support for encap will have
2184 to translate machine type 29k into the right COFF_MAGIC.
2186 * infcmd.c: Remove references to inferior_pid that aren't used
2187 in actual ptrace calls; use target_has_execution, etc.
2188 (have_inferior_p): Remove function.
2189 (program_info): Print target info rather than "process number";
2190 avoid gratuitous messages unless from_tty.
2191 (run_stack_dummy, finish_command): Set proceed_to_finish.
2192 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
2193 main.c: Lint. Lose have_inferior_p().
2194 inferior.h (have_inferior_p): Remove, lint.
2195 (proceed_to_finish): Add flag to ask that all regs be saved
2196 by normal_stop, for the few commands that need it, speeding up
2197 serial I/O. Add comments to stop_registers.
2199 * remote-eb.c: Remove newline from breakpoint message we grep
2200 for. Never time out when running the user program.
2204 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2206 Roll in changes from vxgdb-5.0.1:
2208 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
2209 symbol in its raw form, we are processing an unlinked ".o" file.
2210 See if the target environment has assigned it an address, using
2211 target_lookup_symbol (VxWorks does), and enter it into the symtab
2214 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
2215 68k versions for a simpler version that assumes zero FP at bottom.
2216 Fixes bug of truncated stack reports.
2218 * target.h (target_lookup_symbol): Define this routine's args
2219 and result, finally.
2221 * target.c (nosymbol): Default routine for target_lookup_symbol.
2222 (target_default): Default lookup_symbol and call_function too.
2223 (files_info): Only print has_all_memory warning if a non-dummy
2226 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
2227 vx_convert_from_virtual): If target does not have floating point,
2228 zero register "values", and avoid doing cross-net conversions.
2229 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
2230 (vx_open): Rearrange code that attaches to target and reads
2231 symbols for all loaded modules, to work if some of the modules
2232 are not accessible. Add symbol_stub() and add_symbol_stub()
2233 as callbacks from catch_errors(). Allow connect attempt to be
2234 interrupted painlessly with ^C (FIXME, there are still some bugs
2235 if the interrupt happens during symbol reading.). Print
2236 final message with puts_filtered, since symbol messages are
2241 * main.c (catch_errors): Only print errstring if non-null.
2242 (command_loop): Avoid an ioctl per command to test ISATTY.
2244 * remote-vx.c (net_load): make static; avoid sophomoric msg.
2245 (vx_xfer_memory): Return correct result!
2246 (vx_files_info): Indicate whether target has float or not.
2247 (vx_lookup_symbol): Complain, not error, if target gone.
2248 (vx_open): Print "Connected" msg before disabling immediate-quit.
2249 [FIXME: lookup_symbol and vx_open changes need testing.]
2251 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
2252 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
2253 contributor lines and update copyrights to 1991.
2255 Changes from an attempted H-PUX host port:
2257 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
2258 defines PT_ATTACH and PT_DETACH but not PT_KILL.
2259 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
2260 * remote-vx.c: include <sys/time.h> for HPUX.
2261 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
2262 "core_file_command" routine to BFD regime. May not work yet.
2264 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
2266 * xgdb.c: Replace X10 version with some VJ version.
2267 (FIXME: Its copyright assignment is not on record.)
2268 * xgdb.c: Update include files to X11R4 (Xaw crud).
2269 (xgdb_display_source, create_text_widget): fix call to
2270 get_filename_and_charpos. Rewack source window stuff for X11R4
2271 (gleaned from include files, and "nm's" of binary libraries, since
2272 I had no doc available).
2273 (append_selection, append_selection_word): Disable with FIXME
2274 since R4 changed interface here.
2275 (create_buttons): Add back the old set of buttons.
2276 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
2278 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
2279 Roll VERSION to 3.94 (not yet final though).
2281 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2283 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
2284 obstack_int_grow, obstack_int_grow_fast): Eliminate
2285 cast on left of assignment, which gives MIPS cc fits and is
2288 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
2289 F_ALIAS. Use printf, not fprintf, when not passing a file
2291 (compare_opcodes): Check that identical instructions have
2292 identical opcodes, complain otherwise.
2294 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
2295 was reported by Roland McGrath.
2296 (unimp): Only match if exactly zero instruction. (Roland)
2297 (branches and traps): Generate all variations of these
2298 instructions with macros, based on a single call that defines
2299 each condition name and its binary representation.
2300 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
2302 * valprint.c (val_print_fields): Take, and use, format parameter.
2303 This means that "p/x struct" again prints the elements in the
2304 desired format. Changed callers.
2306 * stack.c (frame_info): Use filtered output, and indicate wrap
2307 points. Remove kludgy formatting designed to avoid line wrap.
2309 * utils.c (wrap_here): If the line is already full (because
2310 we had printed a long indent or long wrapped string), do an
2311 immediate newline-and-indent.
2313 * m68k-pinsn.c (print_insn_arg): Bugfix from
2314 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
2315 instruction is incorrectly disassembled as bkpt #8.
2317 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
2318 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
2319 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
2320 and then will dump core (sometimes). I traced it back to an
2321 uninitialized symfile_name in psymtab_to_symtab.
2322 (const_vol_complaint): Add quotes to message.
2323 (define_symbol): Only believe line number if gcc_compiled.
2324 Avoid allocating symbol if we will not return it.
2326 Add target strata support so that newly established targets go
2327 into their right place in the target stack (e.g. a new exec file
2328 doesn't wipe out the ability to access the running process).
2330 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2331 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2332 and initialize it properly in all the targets.
2334 * target.h: Document strata. Change return type of push_target.
2336 * target.c (nomemory): new function for dummy memory access.
2337 (tcomplain): Rename complain, now also used in symfile.c.
2338 (push_target): Push targets within strata. New return value shows
2339 whether new target is on top of stack or not. Always keep dummy
2341 (target_files_info): Ignore dummy target.
2343 * core.c (core_open): Warn user, and skip accessing file, if the
2344 core target is not the topmost target in the stack.
2345 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2348 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2349 target_ops, it doesn't belong there since we have no regs there.
2350 Change name of target from machine => memory to clarify.
2352 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2354 * Freeze version 3.93 for release.
2356 * Makefile.dist: Handle vx-share and nindy-share subdirs
2357 properly when building gdb.tar.Z.
2359 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2360 printed in various places, so I could change just one copy.
2362 * dbxread.c, coffread.c: Change references to bfd->iostream
2363 to cast to FILE *, now that BFD avoids needing types defined
2364 in other header files.
2366 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2368 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2369 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2370 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2371 (actually gcc -Wall).
2373 * dbxread.c: Remove first_global_sym, last_global_sym, since
2374 they are never referenced.
2376 * defs.h (baud_rate): Declare.
2377 main.c: Define it, and add the -b option to set it.
2379 * gdb-int.texinfo: Add text on how to define a new host or target
2380 architecture, prompted by Per Bothner's questions about MIPS
2383 * gdb.texinfo: Document "complaints". Change doc of -q since
2384 gdb no longer prints the copyright and blurb if you specify a file
2385 name to be debugged (just like Emacs). Add doc for Nindy-specific
2386 command line flags for specifying target serial port and such.
2387 Update copyright to 1991.
2389 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2390 has taken over for us the job of ripping up executable files. The
2391 crud caused Per Bothner's port to not compile.
2393 * infrun.c (normal_stop): Avoid printing "Program exited
2394 normally" if we are in batch mode. This allows a GDB which
2395 executes a program on a target system, to behave like a Unix
2396 command (input from stdin, output to stdout, no extraneous
2399 * main.c (main): Allow additional machine-dependent command line
2400 options to be specified with the ADDITIONAL_OPTIONS,
2401 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2402 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2403 processing to occur just before the main loop with
2404 BEFORE_MAIN_LOOP_HOOK.
2405 (main): If a "core file" argument is specified, and it is not a
2406 core file, try it as a process ID to attach.
2407 (symbol_completion_function): Attempt to cope with
2408 "show screen-" TAB, not very successfully. This needs more work,
2410 (batch_file): New function, returns whether we are reading
2411 commands from an interactive tty on stdin, or from somewhere else.
2412 Called by normal_stop since it doesn't get from_tty passed down
2413 to it like many commands do.
2415 * remote-nindy.c: Handle command line options for nindy
2417 (nindy_before_main_loop): Prompt user for tty name if they
2418 don't specify it before getting to the interactive command loop.
2420 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2421 and -r command line options. Also add hook before main loop
2422 to make it easy to specify a tty.
2424 * TODO: More things to do, one done.
2426 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2428 * dbxread.c: Make complaint() calls pass pointer, not struct.
2429 Add complaints about badly formatted C++ type information
2430 (const/volatile indicator, and parse errors resulting in
2431 error_type). Fix C++ virtual member fn comment.
2432 (read_struct_type): Avoid bumping pointer if we got a parse
2433 error; this prevents our walking beyond the end of a string.
2434 Terminate loop on null char as well as semicolon.
2435 (process_one_symbol): Fix the LBRAC fix so that it uses the
2436 last previous SLINE, FUN, or SO record's PC address. C++ debug
2437 symbols did not have SLINE records in a useful order compared
2438 to the LBRAC records.
2439 (define_symbol): Handle "catch" records.
2441 * symtab.c (check_stub_type): Added new complain
2442 `stub_noname_complain' and added a consistency check to
2443 keep the debugger from crashing when finishing from an
2444 exception frame. A real fix will be needed later.
2446 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2448 * infcmd.c (attach_command): Make global.
2450 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2451 but make them easy to comment out. Perhaps later they should
2452 be enabled by what CPU you configure for? FIXME.
2453 (VERSION): Roll to 3.93.
2454 (pinsn.o): Remove rule for obsolete file.
2455 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2457 Run down a problem that manifested by printing the wrong function
2458 name in stack traces of read_ofile_symtab. Turned out that the
2459 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2460 the LBRAC symbol with an address in the *data* segment, which
2461 blew our binary search through the blocks.
2463 * dbxread.c: Use the complain() facility consistently to bitch
2464 about problems in the symbol file we are reading.
2465 (finish_block): Add code to check the nesting of the blocks;
2466 complain and Procrust them to fit if wrong.
2467 (make_blockvector): Check the order of the blocks, complain
2468 [but don't cope] if wrong.
2469 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2470 symbols to be sure their PC value is greater than the last SLINE
2471 (line number) symbol we've seen, complaining and adopting the
2472 SLINE PC value if wrong.
2474 * symfile.h (struct complaint, complaint_root, complain,
2475 clear_complaints): Add.
2476 * symfile.c (complain, complaint_root, clear_complaints): Add
2477 facility to deal with non-fatal complaints and to regularize their
2479 (symbol_file_add): Clear complaint counters to allow new complaints.
2480 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2482 * dbxread.c (dbx_symfile_read): Remember the address and size
2483 of the string table for the main symbol file, so we won't read it
2485 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2486 to avoid reading the string table yet again. Lint.
2487 (throughout): Improve filtered output, including word wrap.
2488 (read_range_type): Improve Bothner's fix to handle other types too.
2490 * utils.c: Improve line wrap implementation. Handle unlimited
2491 width by making chars_per_line unsigned.
2492 (puts_filtered): New, easy, function.
2494 * defs.h (puts_filtered): add.
2496 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2497 call the identical sort_symtab_syms() in symfile.c instead.
2499 * expread.y: Suggest the `file' command rather than `symbol-file'.
2501 * command.h (enum var_types): Add zinteger for seroable
2503 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2504 nested if's into a switch.
2506 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2507 we did not stop because of a breakpoint (it must have been for
2508 some other reason, like a "stepi"), so don't print anything.
2510 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2511 doesn't include <sys/types.h>, old SunOS's require it for
2514 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2516 A test port of gdb-3.92.6 to the Sony NEWS.
2519 Don't normally link in remote- or vx stuff.
2520 Some of it doesn't compile, and it wastes space for 99% of the users.
2521 Remove reference to no-longer-used HAVE_VPRINTF.
2522 Fixed BFD_DEP typo to BFD_DIR.
2524 Fix cast in arg to bfd_h_getlong.
2525 Make char *prefix be const.
2526 Fix how certain range types are mapped into builtin unsigned int types.
2528 Remove 2 #includes. They cause errors (on Sony, at least),
2529 and aren't needed (they wern't in earlier versions).
2531 print_address_symbolic should never demangle labels
2532 (since it prints *assembler-level* labels).
2534 [This was superseded by the change to printcmd below.]
2537 Add some "volatile" return types to avoid warnings.
2538 If MISSING_VPRINTF add vprintf function and not just macro
2539 (since vprintf is used in printcmd.c).
2541 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2542 (The latter isn't grokked by some PCC-based compilers.)
2544 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2546 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2547 * nindy-share/coffstrip.c
2548 Added some forward declarations (otherwise, gcc complains
2549 about implicit extern redefined as static).
2551 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2553 Changes inspired by Per Bothner:
2554 * printcmd.c (print_address_symbolic): Take additional parameter
2555 specifying whether to demangle.
2556 (print_address): Pass in asm_demangle to control demangling.
2557 (print_address_demangle): New fn, takes explicit arg to control
2559 * utils.c: Add new vars demangle and asm_demangle, and let them
2561 (fputs_demangled): If !demangle, just print the argument.
2562 (fprint_symbol): If !demangle, just print raw symbol.
2563 * valprint.c (val_print): Call print_address_demangle rather than
2564 print_address, to cause demangling to depend on the global
2565 rather than assembler-level demangling setting.
2566 * WHATS.NEW, gdb.texinfo: Document.
2568 * main.c (show_command): Show all settings if no arg.
2569 (initialize_main): Make "info set" the same as naked "show".
2570 * command.c (cmd_show_list): Handle prefix commands in the
2571 list, and print the name of the setting as well as its English
2572 description and value.
2574 Allow gdb functions to specify where a line should wrap if it
2575 exceeds the size of a terminal line. Use it to make the output
2577 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2578 of the right size when screen width changes.
2579 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2580 (wrap_here): New fn, indicates a point in the output where we
2581 should wrap the line rather than just letting it overflow at a
2583 (fputs_filtered): Implement wrapping.
2584 (n_spaces): New fn, returns a pointer to N spaces.
2585 (print_spaces_filtered): Use n_spaces.
2586 * defs.h (n_spaces): Declare.
2587 * stack.c (print_frame_info): Wrap with 4-space indent after
2588 fn name and before filename and line number.
2589 * printcmd.c (print_frame_args): Wrap with 4-space indent
2590 before each argument name is printed.
2591 * valprint.c (value_print): Wrap with no indentation before
2593 (val_print_fields): Wrap with indentation relative to nesting
2594 level before each field name.
2595 (val_print): Wrap with nesting indentation before array elements.
2596 * command.c (do_setshow_command): Avoid extra newlines,
2597 wrap with 4-space indent around values printed, end with period.
2598 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2600 * breakpoint.c (breakpoint_1): Implement addressprint for
2601 "info breakpoints" display. Change file name and line number
2602 format to " at file:nnn" rather than " (file line nnn)".
2603 * gdb.texinfo: Document.
2606 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2608 Frozen for gdb-3.92.6 release.
2610 README, WHATS.NEW: Update for 3.92.6 release.
2612 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2613 coffread.o from configs since it is now built by default.
2614 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2615 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2616 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2617 from configs since it is now built by default.
2619 Makefile.dist: Update for release 3.92.6. Handle files that
2620 have been moved to ../include, ../getopt, or ../bfd. Add
2621 saber.suppress and tests directory. Add config.status to
2622 the release (it will say "none").
2624 coredep.c: Minor formatting fixes.
2626 These changes were made in early December but only checked in now:
2627 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2628 nindy-share/nindy.c: lint
2629 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2630 register values coming back from the target; we store values
2631 in target byte order everywhere.
2633 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2635 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2637 * valprint.c (cplus_val_print, val_print_fields): New functions,
2638 which print C++ objects. They conspire to avoid printing a
2639 virtual base class more than once, following all the twists and
2640 turns of C++ virtual base rules.
2641 (val_print): Call the above rather than do it by hand.
2643 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2644 symbol file, not for added files like shared libs. This really
2645 needs to be generalized to a timestamp per file.
2647 * core.c (cleanup_core): Avoid coredump if no core file.
2649 * config.gdb: Accept -host or -target in place of +host or
2652 * coffread.c (find_linenos): Avoid desupported BFD interface
2653 to line numbers. We still read them manually rather than using
2654 BFD's "generic" features.
2656 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2658 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2660 * Makefile.dist: Eliminate use of $< in explicit targets.
2662 * readline/Makefile: Use $< rather than $*.c, which does not
2663 include the VPATH in GNU Make.
2665 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2666 copies of tconfig/i960, added for global configuration
2667 compatability. All i960 versions can read both coff and b.out.
2669 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2670 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2673 * TODO: Think of more things to do.
2675 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2677 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2678 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2679 64-bit float conversion.
2681 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2682 equivalent to sun?os4 so global config works.
2684 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2686 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2688 * main.c: Only declare linesize once; declare pagesize not at
2689 all, since it is never used.
2690 (main): Clear newly allocated line before it is used.
2692 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2694 Further stabilization for the Intel 960.
2696 * Makefile.dist: Parameterize the location of the "include"
2697 and "bfd" directories, as well as "getopt". Add symfile.c.
2698 Link in both dbxread and coffread. Fix up "make depend" to
2699 rewack the locations of include, bfd, and getopt in its output.
2701 * README: Document moving include files, improve some of
2704 * coffread.c: Move common code out to symfile.c. Change
2705 symbol_file_command style interface to use new *_symfile_init
2706 and *_symfile_read interface under BFD. Use BFD internal
2707 info to locate line table, symbols, etc.
2709 * core.c (core_fetch_registers): Rename to get_core_registers
2710 to avoid confusion with fetch_core_registers.
2711 (register_addr): Move to coredep.c, which is already machine
2712 dependent. This leaves core.c pretty clean of dependencies.
2714 * coredep.c (register_addr): Accept this routine from core.c.
2716 * dbxread.c: Move common code (with coffread.c, etc) into new
2717 symfile.c. Each psymtab now contains a pointer to the
2718 format-dependent function that knows how to read it in. Make
2720 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2721 (process_one_symbol): Add code to complain about a "compiler bug
2722 we muzzle here", if we actually see it.
2724 * eval.c (evaluate_subexp): Insert missing "break" statements
2725 in code that determines whether a variable is an lvalue in
2726 memory, register, or whatever. I detected this via a compiler
2727 bug in which it *almost* mashed out the whole switch statement.
2729 * gdb-int.texinfo: Add minor sections on configuring gdb for
2730 release, and about the README file.
2732 * infcmd.c (registers_info): Fix formatting somewhat. Still
2733 not as pretty as before, but it handles byte swapping.
2735 * remote-nindy.c: If data cache routines are interrupted while
2736 waiting for the remote end, be sure that any uninitialized cache
2737 blocks are on the free list, not on the valid list!
2739 * symfile.h: Flesh out this header file with all the various
2740 routines and variables that have been merged in from dbxread.c
2741 coffread.c, and symtab.c to symfile.c.
2743 * symfile.c: New file, containing code common to dbxread.c,
2744 coffread.c, and some code from symtab.c. All generic code for
2745 reading symbol files should be in here now.
2746 (unrecord_misc_function): Remove unused function.
2748 * symtab.h: Remove file-reading things to symfile.h.
2750 * symtab.c: Remove file-reading things to symfile.c.
2752 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2753 to decode i960 fault types.
2755 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2756 target.c: Change type of the "resume" function from int to void,
2757 since its result was never used.
2759 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2761 * main.c: Replace "stupid" with "caution"; you now "set caution
2764 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2766 * infcmd.c (do_registers_info): Call val_print to deal with the
2767 byte order of the registers being printed. FIXME, this makes
2768 the formatting of the output uglier.
2770 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2771 defined, call it for signals the debugger doesn't itself use.
2772 The i960 uses this for more detailed fault information.
2774 * remote.c (remote_open): If arg is null, print help rather than
2777 * sparc-xdep.c (register_valid): Avoid declaring size, since
2778 various modules will think of various sizes depending on the
2779 architecture of their tm-file. FIXME, we need protection against
2780 actually entering one of those modules, which would clobber
2781 storage if not for the target architecture compiled into gdb.
2783 * stack.c (up_command, down_command): Always print the frame
2785 (up_silently_command, down_silently_command): New commands
2788 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2790 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2791 more parameters than it used to.
2793 * findvar.c (registers): Increase slop to 256 bytes, which should
2794 protect us against even most RISC machines with large register
2796 (locate_var_value): Move declaration inside related ifdef.
2798 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2799 throughout, to avoid throwing away buffered input from the board.
2800 (nindy_wait): Supply_register takes addr_of_value, not value.
2801 (i960_print_fault): Renamed from i80960_fault.
2802 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2803 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2805 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2806 we can set the PC in the call to proceed(). Unpush nindy_ops
2807 before pushing it on top, to avoid message to user. Eliminate
2808 commentary from Unix machines that just misleads here.
2809 (reset_command): Fix error message to suggest target command.
2811 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2813 Release 3.92.5 as frozen.
2815 Stabilize the merged release...with help from lint, Saber C,
2818 Everywhere: Add include files needed to declare return types
2819 of functions called.
2821 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2823 * breakpoint.h: Add undeclared breakpoint functions, and some
2824 functions for display handling since I couldn't think of a better
2827 * breakpoint.c (insert_breakpoints): Make code for disabling
2828 shared library bkpts more likely to work. It's used when we
2829 rerun a program and stop before the shared library has been
2831 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2832 cast from pointer, so it squeezes through catch_errors.
2833 (bpstat_stop_status): Fix logic broken some time ago. We now
2834 always create a bpstat if the stop address matches a breakpoint,
2835 even if we don't stop there -- just like the old code used to do
2836 before I got my fingers into it (sigh).
2837 (breakpoint_1): Print "ignore count" after "stop only if"
2838 condition, since that's how it actually works.
2839 (mention): Handle watchpoints as well as breakpoints.
2840 (watch_command): use set_raw_breakpoint and mention to do most
2841 of the work (and initialize all the fields!). Only pass one
2842 arg to parse_c_expression, since that's all it takes.
2844 * command.c (not_just_help_class_command): Rename arg to args
2845 since we ignore "unused argument" warnings on vars named "args".
2846 inflow.c (child_terminal_info): ditto.
2847 infptrace.c (kill_inferior): ditto
2848 main.c (catch_errors, version_info, quit_command, pwd_command,
2849 source_command, dump_me_command, editing_info,
2850 set_history_size_command, set_history, show_history,
2852 stack.c (locals_info): ditto
2853 target.c (target_files_info): ditto
2854 valprint.c (set_input_radix, set_output_radix): ditto
2856 * core.c: Remove old variables for handling core and exec file
2857 sections (data_start, data_end, stack_start, stack_end,
2858 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2859 text_end, exec_data_start, exec_data_end, text_offset,
2860 exec_data_offset, data_offset, stack_offset). They're
2861 superseded the more general build_section_table and
2863 (get_exec_file): Mention the `file' command.
2864 (read_memory_check): Rename to memory_error, and only call it
2865 in the case of an actual error.
2866 (read_memory, write_memory): call memory_error.
2867 (core_fetch_registers): Register section name is ".reg".
2869 coredep.c: Remove a bunch of crud now that all this file does
2870 is pull the registers out of a core file.
2871 (fetch_core_registers): Rewrite to actually work, I hope.
2873 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2874 Replace index() with strchr(). Remove all the pre-BFD macro
2875 definitions for accessing the symbol file.
2876 (struct dbx_symfile_info): Encapsulate the information that
2877 dbx_symfile_init needs to pass to dbx_symfile_read in this
2880 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2881 dbx_symfile_discard): Rearrange symbol file reading to divide
2882 the format-specific part from the format-independent part,
2883 leaving the format-independent part such as file name expansion
2884 and opening in symtab.c. This replaces
2885 partial_symbol_file_open and partial_symbol_file_read.
2886 Symbol_file_read, add_file, add_file_target_command,
2887 add_file_addr_command move to symtab.c. Pass an explicit
2888 "mainline" flag for when reading the main symbol table, rather
2889 than relying on the offset address to be zero or nonzero.
2891 (dbx_symfile_read): Don't allow void *'s to be printed as
2893 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2894 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2895 macro" debug version really work.
2896 (read_dbx_symtab): Remove unref'd parameter inclink.
2897 Avoid swapping N_SLINE symbols, for speed.
2898 Merge N_TEXT!N_EXT case with the other external symbol
2899 definitions' case. Add comments.
2900 (start_psymtab): Allocate the symfile name in the psymtab on
2901 the psymbol_obstack, rather than using the caller's storage.
2902 (end_psymtab): Only allocate a dependencies list if there are
2904 (psymtab_to_symtab_2): Use BFD when reopening file to read
2905 its symbols for real.
2906 (read_struct_type): Add FIXME comments where it needs work
2908 (read_huge_number): Add FIXME about overflows.
2909 (read_range_type): Add FIXME about comparing a long to 1<<32.
2911 * coffread.c: Minor changes to move things closer to the new
2912 regime with symtab.c and dbxread.c Major work is still needed
2915 * exec.c (exec_file_command): Remove old variables (see core.c
2917 (xfer_memory): If memory transfer is right at the end of a
2918 section, don't lose.
2920 * findvar.c (get_saved_register): If value is in a real
2921 register, LVAL is lval_register, not lval_memory.
2923 frame.h: Declare print_sel_frame and record_selected_frame.
2925 gdb-int.texinfo: New file, for GDB internals documentation.
2926 Very simple, unformatted doc of cleanups is there for now.
2928 gdbcore.h: Remove obsolete variables that described a.out
2929 section addresses and offsets. (See core.c above.)
2930 Declare fetch_core_registers and registers_fetched.
2932 getopt.c: Declare char *alloca(); even on SPARC.
2934 infcmd.c (run_command): Call target_kill rather than
2936 (step_command, next_command, stepi_command, nexti_command):
2937 Declare from_tty parameter even though we don't use it.
2938 (run_stack_dummy): argument BUFFER is a char array, not
2939 a pointer to REGISTER_TYPE.
2940 (finish_command): using_struct_return needed a value *,
2941 not a struct symbol *.
2943 * infptrace.c (child_xfer_memory): To avoid dependency on
2944 where sections are in memory, try PT_WRITE_D and if that fails,
2945 try PT_WRITE_I. Most Unixes don't care which you use.
2947 * infrun.c (step_resume_break_shadow): Change to array to
2948 match other breakpoint shadow storage.
2949 (clear_proceed_status): Pass address of bpstat to
2950 bpstat_clear, not the bpstat itself.
2951 (child_create_inferior): FIXME comment about if the child
2953 (start_inferior): Remove old function.
2954 (child_open): Use target_kill rather than kill_inferior.
2955 (wait_for_inferior): Ditto.
2956 (insert_step_breakpoint, remote_step_breakpoint): Use
2957 new step_resume_break_shadow.
2959 * inftarg.c (child_wait): If all child processes die,
2960 pretend that the one being waited for exited with signal 42.
2962 * main.c (command_line_input): When scanning for comments,
2963 don't coredump on unclosed quotes.
2964 (quit_command): Use target_kill rther than kill_inferior.
2965 (_initialize_main): Rename class_user from "user" to
2968 * printcmd.c (print_command_1): Initialize "fmt" if no format
2969 is specified by the user.
2970 (print_frame_args): Only add to args_printed if we are
2971 actually fetching args from the stack (avoiding undefined
2973 (_initialize_printcmd): Remove bogus \{ from string.
2975 * remote-eb.c (eb_open): Avoid coredump on no argument.
2977 * remote-nindy.c: Bring out of Intel environment into new
2978 target environment. Remove all conditional compilation on
2979 I80960. Massive hacking throughout.
2980 (nindy_xfer_inferior_memory): New routine stolen from
2982 (nindy_create_inferior): New routine pieced together, probably
2983 not quite working yet.
2984 (nindy_ops): New target_ops struct for nindy.
2986 * remote-vx.c: Use write_memory rather than target_write_memory
2987 to get error checking.
2988 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2990 (vx_create_inferior): Use target_terminal_ours...
2992 * signame.c (_initialize_signame): Always initialize, since
2993 we need the table for things other than psignal.
2995 * solib.c (solib_add): Use symbol_file_add, not add_file.
2996 (solib_address): Return boolean result rather than struct
2997 pointer which nobody else knows the type of.
2999 * sparc-tdep.c, valops.c: Use write_memory rather than
3000 target_write_memory, to get error checking.
3002 * stack.c (locals_info, catch_info, args_info,
3003 get_selected_block, frame_command, up_command): Use
3004 target_has_stack, rather than have_inferior_p or
3007 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
3009 * symfile.h: New file, defining the interface between the
3010 generic and object-file-specific symbol reading code.
3012 * symtab.c: Move generic symbol-reading interface to symtab.c,
3013 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
3014 table to map BFD targets to symbol-reading modules in GDB.
3015 Change index to strchr.
3016 (lookup_struct_elt_type): Use error() rather than hand-made
3017 simulations thereof.
3018 (lookup_partial_symbol): Speedup slightly when length == 0.
3019 (symbol_file_add): New function.
3020 (symbol_file_command): Call it.
3021 (symfile_open, symfile_init): New function.
3022 (add_file_target_command, add_file_addr_command): moved from
3025 * target.c (target_command): use target_kill.
3027 * target.h (target_files_info): Don't declare, never called
3030 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
3031 files to determine stack end address.
3033 * valarith.c (value_x_binop, value_x_unop): Change error message
3034 to be more useful. Pass proper argument to value_struct_elt.
3036 * valops.c (value_assign): FIXME comment that long long
3037 bitfields will break here.
3039 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
3040 Update `make saber_gdb' to work better.
3042 * TODO: A woman's work is never done.
3044 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
3045 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
3046 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
3047 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
3048 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
3049 valops.c, valprint.c, exec.c: Lint.
3052 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
3054 Continuing Intel 960 port merge of GDB.
3056 * Makefile.dist: Merge i960 "nindy-share" files. Rename
3057 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
3058 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
3059 Wack over "make depend" so it handles files in subdirectories
3060 vx-share, nindy-share, bfd, and in the current directory.
3062 * blockframe.c (get_prev_frame_info): Remove fatal error
3063 if stack not defined.
3065 * core.c (core_open, core_detach): New functions that handle
3066 the old "core-file" command as "target core" and "detach" instead.
3067 (core_file_command): Call them.
3068 (core_xfer_memory): Use common routine xfer_memory.
3070 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
3071 dbxread now uses bfd for everything but symbol reading itself.
3072 BFD internals are used to drag out the relevant file offsets.
3073 (partial_symbol_file_open): Change args all around for BFD.
3075 * symtab.c: Rename "value" to "val" everywhere, so we can
3077 (symbol_file_command): New command, moved from dbxread.c
3078 and coffread.c. It uses BFD to read the file, then vectors
3079 based on its type, to dbx or coff symbol readers.
3080 * symtab.h: Extern a few vars for symbol_file_command.
3082 * target.h: Breakpoint takes a char * save area, not a char **.
3084 * valprint.c (val_print): When unpacking bitfields, offset
3085 the address in gdb of the value, if it is declared with a shorter
3086 type. Remove the last "runtime kludge test" of host byte order.
3088 * utils.c: Remove old my_bfd_read routine.
3090 * stack.c (frame_info): Use target_has_stack. Print program counter
3091 register's actual name rather than "pc", since it's called the
3092 "ip" (instruction pointer) on the i960 (sigh).
3094 * target.c (target_command): Add command for selecting a target
3095 type and calling its open routine. This is used for initiating
3096 communication with a particular target, in a generic way.
3098 * tm-i960.h: Update for modern gdb. Remove semicolons from
3099 various macros. Handle reading struct return convention, and
3100 error-out attempts to return structs with the "return" command.
3101 Be sure gdb doesn't think we know how to call functions in the
3104 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
3105 to i960_xxx in lower case.
3106 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
3107 not being defined yet.
3109 * remote.c (remote_open): Call start_remote to initialize
3110 wait_for_inferior during open.
3111 (remote_xfer_inferior_memory): Return length written rather
3114 * remote-vx.c (target_command -> vx_open): Use new generic
3116 * remote-eb.c, inftarg.c, exec.c: ditto.
3118 * infrun.c: Fix comments.
3119 (attach_program -> child_open): Use new generic target command.
3120 (wait_for_inferior): Clear saved register values before target_wait,
3121 so target_wait can set some of them if convenient.
3123 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
3124 Return success indicator, not void.
3125 (child_xfer_memory): Avoid fetching initial word if we'll
3126 overwrite it anyway.
3128 * infcmd.c (attach_command): Use new generic target open routine.
3129 (_initialize_infcmd): Update doc on attach and detach commands.
3130 (do_registers_info): Merge in a byte-order problem as a FIXME
3133 * findvar.c (find_saved_register): Avoid problem in current frame.
3134 (read_relative_register): Ditto.
3135 (write_register): Convert byte order on the way out.
3137 * exec.c (file_command): Add.
3138 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
3139 (xfer_memory): Common function between core_xfer_memory and
3141 (exec_xfer_memory): Use it.
3143 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
3145 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
3146 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
3147 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
3149 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
3151 Merge Intel 960 port of gdb, continuing...
3153 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
3154 symbol_file_command): Pass from_tty arg to hush 'em up.
3156 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
3157 Add magic numbers for 960 COFF format.
3159 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
3161 Merge Intel 960 port of gdb, from Intel "1.2" release.
3163 CHANGE_LOG entries from their port, which was based on
3166 Thu Sep 6 11:02:22 PDT 1990
3167 Remove temp file if download is interrupted.
3169 Wed Aug 1 09:08:33 PDT 1990
3170 Now uses binary protocol to talk to NINDY.
3171 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
3172 Times out after 5 seconds when trying to talk to NINDY.
3174 Tue May 29 12:54:49 PDT 1990
3175 Added variable baud rate (-b switch).
3176 Source code reorganization.
3178 Thu Apr 26 11:09:55 PDT 1990
3179 More cleanup of batch mode; specifically, execute "-s", "-e", and
3180 "-se" switches as soon as they are encountered on the invocation line.
3182 Fri Apr 20 13:47:15 PDT 1990
3185 Thu Apr 19 09:54:28 PDT 1990
3186 Add 'reset' command.
3188 Wed Apr 18 09:48:07 PDT 1990
3189 After opening remote tty, wait for 1 second to go by without input
3190 from it before trying to talk to NINDY (fixes problems with the
3191 Heurikon HK80/V960E).
3193 Mon Apr 4 16:33:05 PDT 1990
3194 Some output was not being suppressed in 'batch' mode.
3196 Thu Mar 22 15:31:11 PST 1990
3197 Ask user if old symbol table should be deleted when new file is
3200 Allow user to run a program downloaded before gdb960 was brought up.
3202 Correct "exec-file" help message for i80960 context.
3204 Correct bug in calculating user space address: could occasionally
3205 corrupt user program.
3207 Make sure to zero low-order bits in rip's because of bug in 960CA
3208 A-step part: could cause operation faults when "next"ing across
3211 Correct bug that made it impossible to get source line numbers for
3212 code loaded at addresses higher than 0x7fffffff.
3214 Wed Jan 10 12:43:22 PST 1990
3215 Open remote tty for exclusive use.
3217 Fri Jan 5 12:14:42 PST 1990
3218 Correct disassembly (CA manual was right after all):
3219 opcode for sysctl is 0x659
3221 Mon Oct 23 12:03:04 PDT 1989
3222 Use G960BASE and G960BIN environment variables to find 'sx' utility.
3224 Mon Oct 16 14:15:09 PDT 1989
3225 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
3227 Mon Oct 2 15:56:31 PDT 1989
3229 Added 960CA disassembly support.
3231 To simplify maintenance:
3232 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
3234 - eliminated opcode.h: incorporates tables into i960-pinsn.c
3235 - moved 960-specific routines from i960-pinsn.c to i960-md.c
3236 - made disassembly interface identical to that in gdmp960.
3240 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
3242 * target.h: Allow targets to stack. Add target_has_memory,
3243 _registers, etc. Restructure memory access and "info files"
3244 to walk the target stack.
3245 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
3246 target.c: Change tables to match target.h.
3247 * inflow.c (child_mourn_inferior): pop child_ops.
3248 (generic_mourn_inferior): Use new has_stack flag.
3249 * infptrace.c (child_xfer_memory): New memory regime.
3250 * inftarg.c (child_files_info): New "info files" regime.
3251 * remote-eb.c: New memory regime, new info files.
3252 * remote-vx.c: New memory regime, new info files. Now use
3253 separate targets for VxWorks attachment to machine, and
3254 actually running a process under VxWorks, since one has
3255 stack & execution & regs and the other doesn't.
3256 * remote.c: New memory regime, new info files.
3257 * sparc-xdep.c (fetch_core-registers): New memory regime.
3258 * target.c: New routines and support for stacked targets,
3259 new memory regime, new info files regime.
3262 Generalize section handling for an arbitrary number of sections,
3263 including use of the new BFD (binary file) library.
3264 * gdbcore.h: Add struct section_table.
3265 * exec.c (build_section_table): Iterate all sections and
3266 record what gdb needs to know about them.
3267 (exec_command): Use it.
3268 (exec_xfer_memory): Use the table.
3269 (exec_files_info): Print the table.
3270 * core.c (core_file_command, core_xfer_memory, core_files_info):
3272 * source.c (find_source_lines): Use bfd_get_mtime.
3273 * dbxread.c: Quick changes to make it compile with new BFD.
3274 * utils.c (error): Avoid using bfd_error in generic routines.
3276 * core.c (core_fetch_registers): Get from the ".regs" section of
3278 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
3280 * inferior.h (attach_flag): Export.
3281 * infcmd.c (run_command): use new target_create_inferior.
3282 * infrun.c (child_create_inferior): Don't return result.
3283 * Makefile.dist (VERSION): 3.91.4.
3285 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
3287 * breakpoint.c (bpstat_num): Handle breakpoints which have
3288 since been deleted, such as temporary breakpoints.
3289 infcmd.c (program_info): ditto.
3291 * core.c (core_file_command): Display the frame where the core
3296 * remote-vx.c (target_command): Merge in target command from
3297 targ-vx.c. A few other cleanups.
3299 * TODO, Projects: Lots more stuff to do...
3301 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
3303 Massive changes to wall off the remote-debugging interface
3304 behind a function vector. The port to handle VxWorks targets
3305 is also part of this.
3307 All files: Replace references to renamed functions,
3308 remove references to remote_debugging, remove references to
3309 have_include_file, have_core_file in favor of target_has_stack,
3310 target_has_memory, etc.
3312 * Modularize the breakpoint interface.
3313 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
3314 a breakpoint instruction.
3315 breakpoint.c: struct breakpoint's shadow_contents now sized as
3317 (insert_breakpoints): Vector to target to install breakpoints.
3318 (remove_breakpoints): Vector to target here too.
3319 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
3320 sparc-tdep.c (single_step): Use new breakpoint interface for
3321 the single-step breakpoints.
3322 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
3323 New file, contains routines to insert and remove breakpoints by
3324 reading out the old contents and later replacing them. This is
3325 how ptrace breakpoints work, and many remote systems as well.
3327 * tm-vxworks68.h: New config file, overrides a few things for
3328 Wind River's preferences.
3330 * target.h: New file, for transfer vector used to talk to the
3331 inferior (child, attached, core, exec, remote, etc). All accesses
3332 to the thing being debugged should come through these vectors.
3333 target.c: New file, routines to handle transfer vector.
3334 (various files): Add transfer vectors XXX_ops for the various
3335 targets and pseudo-targets (core files, etc) we support.
3337 * breakpoint.c (bpstat_stop_status): Further explorations of
3338 watchpoints and why things don't work all the time.
3339 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3341 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3342 the local gdbinit if it doesn't already have it.
3344 * core.c (core_ops): add and install.
3345 Allow core debugging without exec file.
3347 * dbxread.c (free_and_init_header_files): Merge two fns.
3348 (end_symtab): Free named symbol table when a new version comes in.
3349 (read_dbx_symtab): Relocate all kinds of symbols with base
3350 address. First step toward handling different text, data, bss
3352 (add_file_addr_command): Renamed add_file_command.
3353 (add_file_command): Vector to remote handler.
3354 Add "load" as an alias for "add-file" command.
3356 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3357 non-returning functions.
3359 * exec.c: Add exec_ops, and push it as a target when an exec
3362 * infcmd.c (run_command): Pass executable file name and arg list
3363 separately when starting an inferior. Permit "run" when no exec
3364 file is specified, for VxWorks.
3365 (detach_command): Move to child_detach in inftarg.c.
3367 * inftarg.c: New file. Unix-child-specific routines, and the
3368 child_ops structure.
3370 * inferior.h (registers): Export "registers" as the way for
3371 target dependent register handlers to find gdb's local copy of
3372 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3373 since it is now used by places that want wait_for_inferior to
3374 handle the grunge but want to see every trap from the inferior.
3376 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3377 Eliminate remote_debugging hooks in terminal handling.
3379 * infrun.c: Replace start_inferior with child_create_inferior.
3380 Move all the hair of Unix shells and ptrace idiosyncracies into
3381 child_create_inferior, so remote handlers don't have to deal.
3382 Remove running_in_shell. Rename stop_after_attach to
3383 stop_soon_quietly, and use it in a few other places where we want
3384 to just call wait_for_inferior and get control back on the first
3385 trap. trap_expected now never takes a value > 1.
3386 (init_wait_for_inferior): Initialize static vars when a new
3389 main.c (gdbinit): Add new hook for .gdbinit file name, let
3390 it be overridden by config files as GDBINIT_FILENAME.
3391 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3392 Both of these are used for VxWorks gdb.
3394 mcheck.c: rename include file "gmalloc.c" to avoid problems
3395 with system include file "malloc.c".
3397 param-no-tm.h: New include file, same as param.h but does not
3398 include the default "tm.h" file. This is used in files where
3399 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3401 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3403 remote-vx.c: New file, VxWorks remote debugging support. Uses
3404 RPC routines that are shared with the target system, in directory
3407 remote.c: Vectorize remote interface.
3409 source.c: Globalize source_path, and make an alias "l" for "list"
3410 since we now have the "load" command.
3412 sparc-xdep.c: Use new param-no-tm.h.
3414 symmisc.c (free_named_symtab): Add new function from Wind River.
3415 However, ifdef it out for now while we think about what it should
3418 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3420 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3421 non-Unix-children handle this with their own code in the target
3424 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3425 source and target lists. Add vx-share to default list of include
3426 directories. Add new files to src and target lists: mem-break,
3427 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3428 ${srcdir} versions of munch and createtags are used.
3430 * valops.c (find_function_addr): Split out of call_function.
3431 (call_function_by_hand): Rename call_function; this function
3432 calls functions in the target by laboriously patching the target
3433 word-by-word with the right stack, args, regs, etc.
3436 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3438 Handle AMD 29000 a bit better.
3440 * remote-eb.c (readchar): Mask received char log to make it readable.
3441 (remote_start): Pass arguments down to executing program.
3442 Make startaddr unsigned.
3443 infrun.c (start_inferior): Accept args, pass them to
3445 infcmd.c (run_command): Pass args down to start_inferior.
3447 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3448 the target object file format.
3449 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3451 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3452 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3454 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3456 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3457 * TODO: We did a few things, we have more to do though.
3459 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3460 * inflow.c (inferior_died): Clear deferred stores.
3462 * Debug problems with dummy frames and calls to the inferior.
3463 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
3464 * sparc-tdep.c (do_restore_insn): Simplify.
3465 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3466 (sparc_push_dummy_frame): Simplify and fix what we push.
3467 (sparc_pop_frame): Slightly more hair here, deciding whether
3468 we are restoring a saved PC or returning to a return address in %i7.
3469 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3471 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3472 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3473 * obstack.h (chunkfun): ditto.
3474 * defs.h (xmalloc, xrealloc): ditto
3476 * utils.c (quit): Grab the terminal from the child if necessary.
3478 * inflow.c (term_status_command): Rename to term_info, change
3481 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3482 (is_delayed_branch): Speed up.
3483 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3484 Still missing some float ops, and needs testing.
3486 * Support for input and output radixes other than base 10
3487 * defs.h (input_radix, output_radix): Declare.
3488 * expread.y (yyparse, parse_number): Handle changes of input
3489 radix, and ambiguous names-or-numbers in radixes >10.
3490 * printcmd.c (print_scalar_formatted): Print formatted hex
3491 numbers in varying column widths.
3492 * valprint.c (val_print): Use output_format to print scalar ints.
3493 (set_input_radix, set_output_radix, set_radix): Create.
3494 (set_output_radix): Set output_format from output_radix.
3495 (_initialize_valprint): add `set radix' but leave the others off.
3497 * main.c (execute_command): Let stupid questions be turned off.
3498 (_initialize_main): Handle "set stupidity", etc.
3500 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3501 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3503 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3505 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3506 bfd stuff is still screwed up, but with some manual work, it
3509 * breakpoint.c (bpstat_do_actions): Start over if a command
3510 proceeds the inferior, since the inferior will have stopped and
3511 will need to have its new stop-actions taken care of.
3513 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3514 compiler fits, simplify it.
3516 * gdb.texinfo (directory command): Doc new dir command.
3517 source.c (directory_command): "dir" now puts things on the front
3518 of the path, moves dups up front, and handles multiple names
3519 on the command line, inserting each one in order. It also
3520 blows away cached line and full_filename info.
3522 * stack.c (backtrace_command): Skip "more stack frames follow"
3525 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3526 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3527 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3528 The only odd one was Gould NP1, which had defined vprintf to
3531 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3532 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3533 variable, inspect_it.
3534 valprint.c (print_string, val_print): Use the global inspect_it
3535 to indicate whether to print in Epoch style or normal style.
3537 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3539 * printcmd.c (call_command): add an alias for the "print" command
3540 which runs expressions and doesn't print the result if void.
3541 (print_command_1): implement it.
3543 * command.c: Remove #if 0'd code. Initialize all the fields
3544 in add_cmd (). Rename do_nothing_command to
3545 not_just_help_class_command, and make it externally visible.
3546 command.h: add user_commands to struct.
3547 * main.c (define_command): Don't overload c->function with a char
3548 string as well as a function pointer.
3550 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3551 calling convention of value_struct_elt () that got dropped in
3554 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3555 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3557 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3559 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3560 until a good time (e.g. when we are about to run the child),
3561 saving ptrace calls.
3562 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3563 * tm-sparc.h: define DO_DEFERRED_STORES.
3565 * sparc-xdep.c (store_inferior_registers): when storing float
3566 registers, don't store stack regs too. When storing the SP,
3567 however, DO store the stack regs too. This fixes a bug in which
3568 the dummy frame is not recognized when a call_function finishes,
3569 because its frame pointer (in the stack regs) was never
3571 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3572 even though we don't know how to read them from an inferior.
3573 valops.c (call_function): Comment about storing SP.
3575 * infrun.c (save_inferior_status): Save away the original bpstat
3576 chain so it can be restored later. Install the copied version for
3577 use by whoever saved the status. It will be blow away by
3578 restore_inferior_status, and the original chain restored. This is
3579 important for people who have pointers into the original.
3581 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3582 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3583 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3586 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3588 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3589 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3590 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3592 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3594 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3595 Store the baseclasses in a type struct starting from array element
3596 0 rather than from the unusual array element 1.
3598 dbxread.c: the above.
3599 (virtual_context): Add
3600 Read new debug information about which virtual function table
3601 a virtual function is from, and store it in fn_field.fcontext.
3603 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3604 TYPE_FN_FIELD_STATIC_P.
3606 symtab.c: the above.
3607 valops.c: the above. Handle pointer casts of object *'s.
3608 (search_struct_method): Add.
3609 (value_struct_elt): First arg is now a pointer to a value, and is
3612 valprint.c: the above.
3613 values.c (value_virtual_fn_field): Add type arg. Handle
3614 offsetting to the proper object when calling virtual fns.
3616 (baseclass_addr): Add valuep arg.
3618 * README: Document the current state of BFD config (missing).
3619 * TODO, ChangeLog, Makefile.dist: Roll version.
3620 * WHATS.NEW: Add summary of changes since 3.5.
3622 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3624 * dbxread.c (read_struct_type): Clear bit vectors whenever
3626 symtab.c (B_CLRALL): define.
3628 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3629 using == rather than =. Huh... This fixes the dreaded problem
3630 wherein builtin_type_int becomes TYPE_CODE_FLT.
3632 * core.c (info_files): Show the inferior pid.
3634 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3635 already knows how to look in the source directory.
3637 * Remove psymtab hair from many places. Remove duplicated code
3638 for searching symbol tables. Hide psymtabs from most places.
3639 Make it fast to get from a psymtab to its symtab.
3641 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3642 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3643 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3644 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3645 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3646 new symtab completely. New psymtabs get symtab pointer
3647 initialized to zero. Remove MI warning printf.
3648 symtab.h: Comments. Add psymtab to symtab pointer.
3649 (PSYMTAB_TO_SYMTAB): New macro.
3650 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3651 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3653 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3655 (print_frame_info): Avoid special-casing symbols that have not yet
3658 * source.c (open_source_file): Quick path if we have already
3659 located the source file by its full name.
3661 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3662 find_pc_psymtab. When a name is found in the misc function
3663 vector, search the symbol table for its mangled name, not the
3664 name that the user typed.
3666 * bfd.h: Fix missing comment terminators, make #endifs match.
3668 * valarith.c (value_less): Handle unsigned int comparisons.
3669 Add FIXME about pointer compares, which assume host and target
3670 pointers are the same.
3672 * command.c (do_nothing_command): lint
3673 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3674 fix comments on debug symbol format for visibility. Actually set
3675 visibility of symbols.
3676 main.c (echo_command): lint; use <readline/history.h>.
3677 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3678 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3679 pointing past end of allocated memory; saber complains.
3680 obstack.h: Declare the external functions that we use.
3681 valarith.h: use <string.h>
3682 solib.c (solib_add): lint.
3684 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3686 * main.c (initialize_main): Default info_verbose to off, now that
3687 symbol reading is fast.
3688 (quit_command): Avoid clobbering exec_bfd while quitting.
3690 * Initial BFD (binary file diddling library) merger:
3691 coffread.c: Change AOUTHDR to struct exe_hdr.
3693 core.c: initialize initialized data at compile time.
3694 (core_file_command): Move from coredep.c, convert to bfd.
3695 (xfer_core_file): Convert to bfd.
3696 exec.c (exec_file_command): use bfd routines.
3698 mips-tdep.c: Remove exec_file_command and friends.
3701 * coredep.c: (fetch_core_registers) Convert core_file_command to
3702 fetch_core_registers.
3703 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3705 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3706 (my_bfd_read): More bogosity, which I don't think we call.
3707 (program_name): Remove this atrocity asap!
3709 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3712 values.c: allocate_repeat_value was not clearing the
3713 optimized_out field.
3714 (value_static_field): minor stylistic fix (wrong macro was used).
3715 valops.c (value_struct_elt_for_address): didn't work for C++
3718 * signame.c (_initialize_signame): Initialize signal names once.
3720 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3721 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3722 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3724 * remote-eb.c: Support user-settable baud rates on the serial port.
3726 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3728 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3730 * tconfig/sun3os4: Remove warning about native assembler,
3731 since it also occurs in the xconfig file.
3733 * findvar.c (registers): Allocate some slop after `registers'
3734 to prevent stray accesses from trashing the next variable.
3736 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3737 on the sun-3, by changing the #ifdef from `sun3' (which is not
3738 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3739 vars, which happened to follow `registers' in the executable.
3741 * readline/history.c (history_search): Heed gcc-2's advice
3742 and parenthesize && inside ||).
3744 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3745 tm-29k.c: Insert FSF copyright headers.
3747 * remote-eb.c: Better comments.
3749 * Makefile.dist: Update to 3.91.6.
3750 * TODO: note PREPARE_TO_STORE problem.
3752 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3754 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3756 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3758 * infrun.c (wait_for_inferior, at end): Don't set up
3759 prev_* if the inferior no longer exists.
3761 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3762 CANNOT_EXECUTE_STACK.
3763 valops.c (call_function): Use it.
3765 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3767 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3768 infrun.c (wait_for_inferior, 2 places): Use it.
3770 * values.c (value_being_returned): Only use
3771 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3773 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3774 right thing for remote-eb.c.
3776 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3777 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3779 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3780 (FRAME_FIND_SAVED_REGS).
3782 * findvar.c ({fetch,store}_registers): Check for
3783 REMOTE_{FETCH_STORE}_REGISTER macro.
3785 * findvar.c (get_saved_register): Add argument lval and
3786 change meaning of argument addr.
3787 findvar.c: Change calls to get_saved_register to reflect
3788 new calling convention.
3789 valops.c (value_assign): Use get_saved_register instead of
3790 find_saved_register.
3792 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3794 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3795 an (uninitialized) pointer to one. Use "&" when passing it
3798 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3800 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3803 * coffread.c (symbol_file_command): Put semicolon after
3805 Put safe_to_init_tdesc_context in #if defined (TDESC).
3806 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3807 coffread.c: #include <sys/stat.h>.
3808 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3809 Add missing ')' in check for "lc%" and friends. Remove
3811 Declare read_one_sym() at top of file.
3812 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3813 MC68WRMAGIC can have the same value without causing a duplicate
3816 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3818 * Allow a Makefile to be built without building the
3819 tm and xm file links that screw up builds in subdirectories.
3820 This is done with `config.gdb none', then you can do things
3821 like `make gdb.tar.Z'.
3822 * tconfig/none: Config file for no target system
3823 * xconfig/none: Config file for no host system
3824 * config.gdb: If no TM or XM files are called out by the
3825 host or target file, don't make links for them.
3827 * cplus-dem.c: Add documentation.
3829 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3830 simple error, so the user's gdb doesn't crash due to some object
3831 file problem (e.g. somebody is rebuilding the file out from under
3834 * printcmd.c (print_address_symbolic): demangle the symbol.
3836 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3837 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3838 (alldeps.mak): sort and uniq all results from this; duplicates
3839 hose gdb.tar.Z link building. Remove RCS files from
3840 tconfig and xconfig. Add config files for sun386. Add
3841 a few odd files to OTHERS and HFILES.
3843 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3845 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3846 Roll version number to 3.91.5. Make lint work in bindir.
3848 * README: Document cross-debugging and new file structure.
3850 * blockframe.c: Lint. Include "value.h" to declare read_register.
3851 (find_pc_partial_function): remove duplicate line.
3853 * command.h: Lint. Declare error_no_arg and dont_repeat.
3855 * tm-news.h: Remove inadvertently duplicated stuff.
3857 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3858 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3860 * config.gdb: Allow `config.gdb host target' form. Clean
3861 up previous change that printed bogus messages when you just said
3864 * core.c: #include "command.h" for lint.
3867 * main.c: Remove some casts of enums. Lint.
3874 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3876 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3877 read it from memory. This will allow us to save ptrace calls
3878 eventually. Changed caller single_step too.
3880 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3881 that we aren't going to use, saving many ptrace calls, especially
3882 when watchpointing or single stepping. Use some #define's for
3884 (store_inferior_registers): Ditto.
3885 (core_file_command): Use some #define's for constants.
3887 * tm-sparc.h: Add #define's for some register numbers, so we
3888 can eliminate the use of random constants in sparc-xdep.c.
3890 * stack.c (frame_command, print_frame_info, up_command,
3891 down_command) Remove frame_changed, since it
3892 causes a bug and doesn't seem to do anything useful. In some
3893 places it was used as a flag, in others as a stack level (?).
3895 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3896 default is to use the portable (vprintf) version rather than the
3898 * xm-news.h (MISSING_VPRINTF): Add.
3900 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3902 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3904 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3905 about linking debugged programs -Bstatic in the sun?os4 config
3906 files in tconfig and xconfig subdirectories.
3908 * main.c (main): Remove unreached exit(0) now that we exit
3911 * Create TODO file for online bug list. There are too many
3912 "little" bugs to keep track of on paper.
3914 * Change Projects file to refer to bug-gdb@cygnus.com
3915 rather than kingdon@ai.
3917 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3919 * Makefile.dist (VERSION): 3.91.4 now.
3921 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3922 (condense_misc_bunches): Add sanity check that misc_count is
3923 the same as the number of symbols in the bunch.
3925 * coffread.c: rename init_misc_bunches. Pass an argument
3926 to condense_misc_bunches (a zero).
3928 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3929 every time we are called; don't rely on our caller to do it.
3930 (add_file): Remove call to init_misc_bunches.
3932 * mipsread.c: Only warn, don't error, if unknown symbol types.
3933 This keeps an old gdb from falling on its face if it sees newly
3934 extended symbol info. Rename init_misc_bunches.
3936 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3938 * Merge in changes from Per Bothner for DECstations and other
3939 MIPS stuff. The rest is Bothner speaking:
3941 The next message is a merger of Alessando Forin's mips port with
3942 mine. I've tried to use my good if biased judgment to get
3943 the best of both. It *does* need testing.
3945 Some of the changes are general, *not* mips-specific.
3948 Didn't believe in little-endian bit order.
3949 There are still inconsistencies about whether flags
3950 like BITS_BIG_ENDIAN are integer (#if ...) or
3951 boolean (#ifdef ...). I tried to paper over them.
3953 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3954 Moved some misc_function code that was common to
3955 {dbx,coff,mips}read.c to symtab.c.
3956 In the process, I think I cleaned things up a bit.
3957 At the same time, moved obsavestring and obconcat to symtab.c.
3960 Removed obsolete condense_addl_misc_bunches (use
3961 condense_misc_bunches(1) instead).
3964 Needed to include <sys/dir>, at least on DECstations.
3966 valops.c, mips-tdep.c, tm-mips.h:
3967 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3968 conventions (when STACK_ALIGN is insufficient).
3969 Needed on mips, where doubles need 8-byte alignment,
3970 but ints only need 4.
3973 Removed cruft that was not being used.
3974 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3977 Print $ before register-names (I think that makes things a little
3979 Never print two instructions, even if one delays.
3980 Removed hex-disassemble set_cmd. (This is not mips-specific,
3981 so I think the argument is whether it is generally worthwhile or not.
3982 I'm inclined to think not, given how easy it is to
3983 convert between radixes in gdb.)
3986 This is basically Alessando's code.
3987 It doesn't use obstacks; I changed it to use obstacks
3988 in a few minor places where using malloc causes a
3989 memory leak. (Probably, more places could/should be changed.)
3990 I added record_misc_function where it was missing.
3991 In symbol_file_command and add_file_command, I tried
3992 to make the code consistent with more recent versions.
3993 Minor sylistic changes in parse_procedure.
3994 Make a .gdbinfo. psuedo-symbol point back to the real
3995 procedure symbol (using the isym field).
3998 This is basically from my port, but with a lot of details
3999 and a number of routines merged in from Alessando's version.
4000 I basically used my code "raw" backtrace (use heuristics
4001 from the actual code, rather than symbol table info) - though
4002 the idea is Alessandro's. I feel my code is a little cleaner
4003 here, particularly in being a little more flexible, such as being
4004 able to handle gcc-produced code (which it now can).
4005 It also doesn't do frame caching (which is not useful
4006 more recent gdb versions).
4007 I also used my code for push_/pop_dummy, more or less.
4008 I tried to incorporate AF's code for testing sigtramp
4009 while backtracing; I probably got it wrong.
4010 Added mips_print_register, which tries to scrunch as much
4011 information as possible on a screen...
4012 Removed the skip-prologue set_cmd. As with hex-disassemble (see
4013 under mips-pinsn.c), I don't see anything mips-specific here,
4014 and I don't see it being all that useful anyway.
4017 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
4018 Use more register names (rather than hard-cases numbers).
4020 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
4022 * Hack up 3.90.11 changes:
4024 * Makefile.dist (depend): parameterize $(GCC).
4025 Add solib.c and solib.o.
4026 (readline): Fix vpath for both absolute or relative SRCDIR.
4028 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
4029 Also, let the part I didn't understand at least compile so
4030 I can test the rest. FIXME.
4032 * dbxread.c: Fix thinko using strcmp.
4033 (init_psymbol_list): declare static.
4034 (partial_symbol_file_open): Comment cleanups better, avoid
4035 cleaning up the string table since the caller will do that.
4036 Move the stat for mod time into symbol_file_command, temporarily.
4037 (There should be a mod time for each symbol file, eventually,
4038 to control its rereading. FIXME.)
4040 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
4041 SunOS, which gives error for shared libs otherwise. (From
4042 Schaefer, probably FIXME needs work for portability.)
4044 * solib.c: Move #include "param.h" to work.
4045 Lowercase all the Uppercase Letters In the Messages.
4046 (find_solib): Clean up inferior_so_name for debug printouts.
4047 Allow no argument, to mean all shared libraries.
4049 * symmisc.c: include param.h to get CLEAR_SOLIB.
4051 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
4053 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
4054 to 3.90.11. ChangeLog entries below are from this.
4056 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4060 * Makefile.dist (HFILES): Add tm-sunos.h.
4062 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4066 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
4068 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
4070 * sparc-opcode.h Added single-operand version of rett.
4072 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4074 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
4075 Put parens around gcc_p in expansion.
4077 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4079 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
4081 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4083 * Changes for Sun shared libraries:
4084 blockframe.c (find_pc_partial_function): If a non-text symbol
4085 is found, set *address = pc - FUNCTION_START_OFFSET.
4086 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
4087 Disable breakpoints instead of giving an error.
4088 source.c (select_source_symtab): Initialize cs_pst.
4089 symmisc.c: Call CLEAR_SOLIB if defined.
4090 symtab.h: Make text{low,high} CORE_ADDR not int.
4091 (psymtab): New field addr.
4093 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
4094 (record_misc_function): Give correct type for N_DATA symbols.
4095 (condense_misc_bunches): do "misc_function_count = j" regardless
4097 Take code which is shared between symbol_file_command and
4098 add_file_command and put it into partial_symbol_file_{open,read}.
4099 Split add_file_command into add_file_command and add_file.
4100 Make psymtab_to_symtab read in the string table if the file
4102 Two new parameters to read_dbx_symtab and start_psymtab.
4103 tm-sunos.h: New file.
4105 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4107 * infcmd.c: Change cont_command to continue_command and "cont"
4110 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4112 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
4114 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
4116 * values.c (USE_STRUCT_CONVENTION): Check for structures of
4117 size 1,2,4,8 rather than size < 8.
4119 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
4120 as necessary, not just once.
4122 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
4124 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4126 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
4128 * tm-news.h: Add CALL_DUMMY_*.
4130 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
4132 * config.gdb: In list_host, list_target, use ${i}, not $i.
4134 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4136 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
4138 * sparc-opcode.h: Change all store floating-point state register
4139 instructions to have the right match & lose fields.
4141 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4143 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
4145 config.gdb: If srcdir != ., create readline directory and
4146 copy a makefile into it.
4148 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
4149 consistency with POSIX.
4151 * breakpoint.c (bpstat_stop_status): Disable watchpoint
4152 when we exit its exp_valid_block.
4154 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
4156 * Makefile.dist: Bump version to 3.91.3.
4158 * Clean up handling of breakpoint commands (somewhat).
4159 Prompted by Tiemann bug report "cont 10" doesn't work any more.
4161 inferior.h: Add breakpoint_proceeded to inferior status struct
4162 and globals; save it and restore it.
4163 (clear_breakpoint_commands): Cleanup, remove old #define.
4165 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
4166 (save_inferior_status, restore_inferior_status): handle it also.
4167 (proceed): Remove earlier code that set breakpoint_proceeded.
4168 It is now set only in clear_proceed_status.
4169 (clear_proceed_status): Cleanup, use bpstat_clear rather
4170 than clear_breakpoint_commands. No callers need the stop_bpstat
4171 between clear_proceed_status and proceed.
4173 infcmd.c: Add breakpoint_proceeded definition and comment.
4174 (cont_command, jump_command, signal_command): Move call to
4175 clear_proceed_status right next to call to proceed.
4177 breakpoint.c (bpstat_do_actions): Avoid clobbering our
4178 caller's argument while running down the chain of breakpoints.
4179 Use new variable "breakpoint_proceeded" to determine when
4180 a command that it executes moves the inferior past the
4182 (bpstat_clear): Handle NULL argument.
4183 (bpstat_clear_actions): Avoid useless call to
4184 breakpoint_auto_delete.
4185 (delete_breakpoint): Clean up bpstat's that are pointing to
4186 the deleted breakpoint from the stop_bpstat chain.
4187 (breakpoint_auto_delete): Simplify.
4189 * Clean up handling of EOF, error on stdin, etc. This was
4190 prompted by a network problem that caused gdb to go into an
4191 infinite loop filling up its malloc'd memory.
4193 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
4194 not clear_breakpoints_commands, which is now gone.
4195 (main): If command_loop returns (e.g. from EOF on stdin), do
4196 a quit_command (looping back to command_loop if quit_command
4197 doesn't really quit).
4198 (command_loop): check result from command_line_input and
4199 exit if it returns NULL, rather than passing the NULL to
4201 (gdb_readline): Free malloc'd result space before returning
4204 * utils.c (query): Handle C-d to mean "yes", just as if the
4205 input was not a terminal. Also avoid infinite loop if EOF
4206 occurs in mid-input-line before newline. This allows
4207 query to be used at EOF on stdin with reasonable results.
4209 * infrun.c (proceed): Set breakpoint_proceeded.
4211 * values.c (value_as_long): Avoid infinite recursion for enums.
4212 (_initialize_values): Fix typo in help msg (kingdon).
4214 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
4215 RL_LIB for linking. This allows -lreadline for linking
4216 and nothing for dependencies, once readline is a real library.
4218 * config.gdb: Jim Kingdon: give useful error message if the
4219 host or target type is not recognized.
4221 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
4222 it just defines it. Dumb, but deal with it.
4224 * Jim Kingdon suggests:
4225 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
4227 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
4229 * Makefile.dist (VERSION): Bump version # to 3.91.2.
4231 * Clean up Bothner's changes.
4233 * blockframe.c (clear_pc_function_cache): New function.
4234 * blockframe.c: remake cache_pc_function_* static.
4235 * dbxread.c (symbol_file_command): remove references to
4236 cache_pc_function_* variables.
4237 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
4238 * printcmd.c: Avoid kludging a global variable (addressprint)
4239 to avoid printing the address of a string twice. Instead,
4240 pass the format letter 's' down low enough that it can be seen
4241 to avoid this problem.
4242 (print_formatted): Pass format arg to value_print.
4243 (restore_addressprint): Remove function.
4244 (do_examine): Avoid hacking addressprint, cleanups and such.
4245 (print_frame_args): Add a comment to a Bothner change.
4246 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
4247 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
4248 to wipe out the values cached in blockframe.c.
4249 * symtab.c (find_method): Add comment saying how big you must
4250 allocate to be "big enough". Per being terse again.
4251 * valprint.c (val_print): Handle format letter "s" to print
4252 strings without addresses. Add comment to vtbl printing code
4253 which casts with wild abandon. Rearrange reference-printing
4255 @0xaddr: value (print w/addressprint)
4256 value (print w/~addressprint)
4257 @0xaddr (parameter lists w/addressprint)
4258 or nothing (parameter lists w/o addressprint)
4260 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
4262 * Merge more changes from Per Bothner:
4264 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
4265 annoying) that I tried to improve it. Here are my suggestions.
4267 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
4270 Do automatic de-reference when taking the address of a reference.
4272 Don't deref_ref when printing parameter lists.
4274 More attempts at treating refernences properly.
4276 In val_print, if deref_ref==0, don't print dangling " = ".
4278 Add COERCE_REF macro, which de-references an REF.
4280 * Merge changes from Per Bothner:
4282 * Fixed (Sony news)-specific configuration problems.
4283 * Fixed other problems with using vanilla pcc and libc (enum problems;
4284 assumption that vsprintf exists).
4285 * Some major speed-ups (finc_pc_partial_function now caches a match;
4286 parsing avoids duplicate symbol_lookup calls).
4287 * Changed handling of baseclasses (no longer use baseclasses field
4288 of struct type, use the first n_baseclasses fields instead).
4289 * Various minor changes/fixes, most C++-related.
4292 Cache the most previous match from find_pc_partial_function.
4293 (Save both low and high ends of matching function's pc range.)
4294 This speeds up the loop of infrun.c:wait_for_inferior quite
4295 a bit, and makes step/next commands much zippier.
4297 Added an enum->int cast (otherwise, some compilers barf).
4299 No longer set baseclass offset to 0, since multiple
4300 inheritance now mostly works.
4301 Added a number of casts, to shut up compiler warnings
4302 (after stabs where made enums, not ints).
4303 When discarding a symbol table (in symbol_file_command),
4304 must clear the cache introduced in blockframe.c.
4305 Don't convert $vtbl_ptr_type to vtbl any more.
4306 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
4307 Mask off sign bit emitted by g++ for virtual table offset.
4308 Set voffset to -1 (not 1) for static member functions.
4310 Changed parsing/lexing of names to avoid doing symbol lookup twice
4311 (once when lexing to determine symbol class, once for real).
4312 Now only call symbol_lookup once. Fields of 'this' win especially big.
4314 Subpress printing addr twice in the case of 'x/s addr'.
4316 lookup_basetype_type is no longer used.
4317 Add find_methods as recursive helper function to decode_line_1.
4318 This allows multiple inheritance to work.
4319 Also, once one or more matches has been found, do not look in
4320 base-classes. (Baseclass methods would be overridden, anyway.)
4322 Removed baseclasses array in struct type.
4323 Instead of using baseclasses[i], use fields[i-1].
4324 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
4325 Changed sign convention of voffset (previous was inconsistent).
4327 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4329 Used to assume existence of vsprintf. Re-written to not need it
4330 if HAVE_VPRINTF is undefined.
4332 typecmp was too pessimistic. Made it less so.
4334 Don't print space after address.
4335 If vtable points to a misc symbol (with 0 offset), print it,
4336 since that indicates the actual class of the object.
4337 Changed ype_print_derivation_info to use new inheritance
4338 scheme (without baseclasses vector).
4340 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4341 Also, changes needed because TYPE_BASECLASSES were removed.
4343 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4345 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4348 If there is no path set, and the symbols don't indicate what directory
4349 a file was compiled in, look in the current directory. But either
4350 a path or a known compilation directory will prevent this.
4353 Three independent bug fixes:
4354 * Remove the #if 0 block that breaks some stuff.
4355 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4356 adapt gdb to either SunOS 4.0.* or 4.1.
4357 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4360 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4363 (type_print) Demangle the name being printed.
4364 (type_print_base) Handle botched demangling without coredump (tiemann).
4367 (check_stub_method): Document routine.
4368 (tiemann) fix bug for no-arg functions
4369 Avoid clobbering beyond end of malloc'd storage.
4370 Terminate the argument list properly.
4372 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4374 * Changes merged by John Gilmore:
4377 In breakpoint_1, use new print_address_symbolic instead
4378 of find_pc_partial_function. (This forces use of assembler-level
4379 addresses, and avoids misleading non-mangled source-level names.)
4381 Generalize ansi argument such that -1 means skip arglist totally.
4382 Removed global variable print_ansi_qualifiers (which made
4383 code non-reentrant), in favor of extra explicit arguments
4384 to internal routines.
4386 Add new helper function print_address_symbolic.
4387 Use find_pc_misc_function instead of find_pc_partial_function
4388 (since we want assembler-level symbols here).
4390 Print unknown function as just "f (...)", not "f (...) (...)".
4391 Use new fputs_demangled explicitly.
4393 Fixed a typing violation (problem: value.h cannot be imported
4394 without renaming many variable in this file).
4395 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4396 decode_line_1: Moved forward some never-reached code.
4397 Made decode_line_2 skip function prologues correctly.
4399 fputs_filtered should not demangle by default.
4400 Add new fputs_demangled to demangle on demand..
4402 Change value_struct_elt to use value_primitive_field (using recursive
4403 utility function search_struct_field). This allows foo.bar to work
4404 for multiple inheritance (so far only for data fields).
4405 Change check_field in the same way (recursive helper function
4406 to support multiple inheritance).
4407 (Note: there are more of these problems that I haven't fixed.
4408 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4409 value_of_this: 'this' symbol name is now just "this", note "$this".
4411 Don't print static members.
4412 Avoid printing "members of <type>" if there are none.
4413 Simplified type_print_derivation_info by merging duplicate code.
4414 Remove useless blank lines in type_print_base (ptype command).
4416 Added declaration of new routine value_primitive_field.
4418 Added value_primitive_field which is generalized version of
4419 value_field that can handle multiple inheritance (non-zero offsets etc).
4420 Re-implemented value_field to call value_primitive_field.
4422 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
4424 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4425 delete the whole environment. Karl Berry reported the bug.
4426 * source.c - fix openp to avoid //'s in filenames, which
4427 trigger an Emacs bug causing it to not be able to find files
4428 when running gdb in a window.
4429 * dbxread.c - zap the #if 0 that botches the add-file code.
4430 It seems to work a lot better without all the code commented out.
4432 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
4434 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
4437 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
4439 * Makefile - added a ${CFLAGS} to a couple of entries,
4440 added remote-sa.sparc.c
4441 * added remote.sa-sparc.c, a modification of remote.c
4442 which conducts a dialog directly with the SparcStation prom.
4443 * breakpoint.c, infrun.c, sparcdep.c added
4444 remote_insert_breakpoint(), and remote_remove_breakpoint()
4445 to breakpoint.c instead of directly writing breakpoint instructions.
4446 * sparcdep.c on remote_debugging,there is no need
4447 to remove signle step breakpoint instructions.
4448 * main.c added "-epoch" flag and "int epoch_interface" to main.c
4450 * printcmd.c - epoch interface sends lisp expressions to open up
4451 epoch windows on inspection.
4452 * valprint.c - added arrayprint, and addressprint and made adding
4453 format controls easier
4454 * wait.h added a couple of undef's because we were getting
4455 complaints about WSTOPSIG and WTERMSIG begin redefined.
4458 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
4460 * symtab.c (decode_line_1): Add support for handling method stubs
4461 in the type information.
4463 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
4465 * values.c (baseclass_addr): Run loop from INDEX+1 to
4466 N_BASECLASSES; otherwise, we can still get into a loop.
4467 @@ This should be restructured to use a cleaner search strategy.
4469 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
4471 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
4472 abbreviation "Tt" for tags which have the same name as their
4475 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
4477 * symtab.c (list_symbols): add ability to set breakpoints on all
4478 the functions which match a particular regular expression.
4480 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
4482 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
4483 should print ANSI qualifiers (such as `const' and `volatile').
4484 All callers changed to call with ANSI == 1, except from
4485 `check_method_stub', which uses old-style syntax.
4487 * symseg.h (struct fn_field): Remove unneccessary `args' field.
