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

729 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
730 symtab.h, target.c, target.h: Lint.
731 * core.c: setup and select frame after reading shared libs,
732 else reading shared libs will clobber them. Lint.
733 * utils.c (error): Force out any buffered wrap text.
735 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
737 * remote.c: Remove decls of memory_insert_breakpoint
738 and memory_remove_breakpoint, no longer used. (Suggestion of
741 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
742 to make it easier to interface to "configure"'d libraries.
744 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
746 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
747 aliases for set/show print.

1298 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
1299 to the main file, as well as to include files. Also, put global
1300 functions into the global psymtab, to make "i fun" work.
1301 (end_psymtab): Free named symtabs and psymtabs for a file, once a
1302 new psymtab for it has been read.
1303 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
1304 a file, once a new symtab has been read for it.
1305 * mipsread.c: FIXME. We need to do the same for MIPS, but it
1306 looks harder to determine the top-level block before it's been
1307 queued to the psymtab list.
1309 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
1310 If we have wiped out any old symbol tables, clean up at end of

1326 static psymbols list.
1327 (types_info): Restore this function from its untimely #if 0.

1344 * symfile.h: free_named_symtab now returns an int.
1346 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)

1349 is the first symbol read, even if not mainline.
1350 (dbx_psymtab_to_symtab): symfile might be zero, cope.
1351 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1352 (set_section_command): New command ("section xxx yyy" -- should
1353 be renamed to "set section xxx yyy" FIXME) which sets the
1354 base address of a section of the exec file, overriding the
1355 virtual address that BFD reports.
1357 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1359 * exec.c: Add add_syms_addr_command to exec_ops, so you can

1364 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1365 for printing the float info is host-dependent, not
1366 target-dependent. FIXME.
1367 * i386-pinsn.c: Move #includes to top, remove useless ones.
1368 * i386-tdep.c: Don't bother including <.../reg.h> since we
1369 don't use it (and it doesn't exist on host systems).
1371 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1372 Convert negative numbers properly.
1373 (ieee_test): Make numbers really random; fix format arg.
1375 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1376 * core.c (core_detach): Unpush core_ops, which might not be on
1377 top. We used to just pop the top, which broke things. Don't
1378 need dont_repeat() any more.
1379 (core_file_command): Psst! Don't repeat it.
1380 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1381 * expprint.c (print_subexp): Avoid switch fallthru on
1382 BINOP_ASSIGN_MODIFY, so we can print += and such.
1383 * frame.h: Fix typo.
1384 * inflow.c (kill_command): After killing inferior, print our
1385 current frame in the core file, if we have one.
1386 (generic_mourn_inferior): When inferior dies, either select
1387 the current frame (in the new target, e.g. core file), or
1388 set both the current and selected frames to NULL.
1390 Changes from Peter Schauer.
1392 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1394 * Make all file names fit in 14 characters (sigh and damn!):
1395 mv hp300hpux-xdep.c hp300ux-xdep.c
1396 mv symmetry-xdep.c symm-xdep.c
1397 mv symmetry-tdep.c symm-tdep.c
1398 mv convex-opcode.h convx-opcode.h
1399 mv tm-vxworks960.h tm-vx960.h
1400 mv tm-vxworks68.h tm-vx68.h
1401 mv Makefile.srcdir Makefile.sdir
1402 mv gdb-int.texinfo gdbint.texinfo
1403 mv remote-sa.m68k.shar rem-m68k.shar
1404 mv remote-multi.shar rem-multi.shar
1405 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1406 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1407 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1410 * command.c (user_info_1, user_info): New command for listing
1411 the user-defined commands.
1413 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1415 * dbxread.c (really_free_pendings): Clear file_symbols
1416 and global_symbols after freeing them; otherwise, running
1417 this function twice (if it appears twice on the cleanup
1418 chain), we try to free things twice.
1420 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1421 based on text_addr (the address of text in core), not on addr (the
1422 offset between text in the .o file and in core). This change
1423 is from Peter Schauer.
1425 * main.c: Define ALL_CLEANUPS as a cast of zero.
1426 (return_to_top_level): Use it.
1427 (main): Do all cleanups after each command run as part
1428 of the gdb startup sequence. Also do all cleanups before
1429 entering the command loop, and every time we exit the command
1430 loop and reenter. Before, the cleanups from the startup sequence
1431 were being left undone until the first error!
1432 (command_loop): Rename do_nothing cleanup to command_loop_marker
1433 so we can see it easily when examining the cleanup chain.
1434 (init_signals): Add another do_nothing for signal handling.
1435 (quit_command): Only try to kill target if it has execution.
1436 Problems in the target stack got us into a state where
1437 inferior_pid was nonzero but none of the targets had execution.
1438 In this state you couldn't exit gdb.
1440 * dbxread.c: Two changes from Peter Schauer.
1441 (echo_command): Fflush output after an echo command.
1442 (show_history): Pass all args to cmd_show_list.
1444 * utils.c (init_malloc): Call mtrace to turn on tracing
1445 if the environment variable MALLOC_TRACE is set to a file name.
1446 * mtrace.c: Add source file which provides a log of every malloc,
1447 free, and realloc to a trace file.
1448 * mtrace.awk: Add source file which analyzes the trace file.
1449 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1450 (VERSION): Roll to 3.94.3.
1452 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1453 (check_duplicates): Don't bother with watchpoints.
1454 (set_raw_breakpoint): Comment about danger of this routine.
1455 (watch_command): Parse and eval all args before calling
1458 * solib.c (find_solib): Avoid error in referencing memory to
1459 see if any more shared libraries have been added. This is
1460 particularly useful if the target has terminated. Bug reported
1463 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1464 in bringing up 3.94.2 on the Sun-3.
1466 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1467 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1468 expression (in scope) before reenabling watchpoint.
1469 * signame.c (init_sigs): Add missing declaration of i, fix
1470 sys_siglist declaration.
1471 * source.c (list_command): Fixed range computation to use
1473 * stack.c (backtrace_command): Do not allow command if target has
1474 no stack, print informative error message.
1475 * target.c (target_command): Do not write into command line
1476 because this fails if the target command is used in a user defined
1477 command. [This change was enhanced by gnu to support any-
1478 unique-prefix matching on target names.]
1479 * valops.c (value_struct_elt): Avoid infinite loop on an
1480 erroneous attempt to print the member of function (try p main.p).
1482 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1484 * expread.y (name_no_typename): Avoid reduce/reduce errors
1485 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1486 Since the GDB parser really doesn't use name_no_typename in a
1487 name-only context, the parser can't tell the diff between
1488 names and numbers here. Avoid allowing a name_no_typename
1489 to be a NAME_OR_*INT to resolve the conflict.
1491 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1493 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1495 * valprint.c (val_print_fields): bitfield printing didn't handle
1496 byte order. Indirect through a few more fns to cope.
1498 * values.c (modify_field): also cope with byte order.
1500 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1502 Cleanup for release 3.94.2:
1504 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1505 include files. Roll version to 3.94.2.
1507 * coffread.c (init_stringtab): Read length into unsigned char
1508 array before swapping; don't assume 32-bit longs.
1510 * target.c (target_info): Don't bother with get_sym_file, just use
1511 the symfile global variable.
1512 * symtab.h, symfile.c (get_sym_file): Delete it.
1514 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1515 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1516 (read_type): Replace one more error() with complain().
1518 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1520 * i960-tdep.c: Fix copyright attribution.
1522 * config.gdb: Quote all backquotes in doublequotes. You can
1523 quote me on that. BSD 4.4 shell found this one.
1525 * infptrace.c (throughout): The third argument to ptrace is an
1528 * infrun.c (wait_for_inferior): When program has terminated, we
1529 have to call target_terminal_ours before we pop that target off
1530 the stack (e.g. before a call to target_kill or
1531 target_mourn_inferior). This fixes problem where a program
1532 terminates, then GDB stops for (tty output) and you have to type
1533 "fg" to the shell to resume it. FIXME: This code for what to
1534 do after termination really should be in normal_stop instead.
1536 * gdbcore.h (read_memory_check): Change declaration; it changed
1539 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1540 4.4 prereleases, this avoids a bug in their sgtty compatability
1542 * remote.c: Use terminal.h rather than hand-rolling the same.
1544 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1545 * utils.c (strsave, strstr): Fix arg types.
1546 * valprint.c (val_print): lint
1548 MIPS symbol table support from Per Bothner:
1550 * symfile.c (symtab_fns): Remove initializer table that needs to
1551 be hacked for each new symbol file format supported.
1552 (add_symtab_fns): New function, chains symbol table
1553 handlers into the global list.
1554 (symfile_init): Search this list.
1555 * symfile.h: Add next pointer, declare add_symtab_fns.
1556 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1557 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1559 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1560 symbol *). Thus, we no longer need the hack to trash
1561 pst->filename. Good, since that hack confused code in symfile.c!
1563 (reorder_symtabs, destroy_all_symtabs): Removed static
1564 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1565 Instead, the latter now uses a temporary array (stack-allocated
1566 from an obstack, and then freed).
1568 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1569 haven't been set in the outermost stBlock of a procedure. This was
1570 a problem with f77 binaries on Ultrix 4.?.
1572 (new_symtab, new_symbol, new_type): Continue changing code to use
1573 obstacks more and otherwise conform to dbxread internal style.
1574 Made the free_code of symtabs be free_linetable (as in dbxread)
1575 instead of free_contents. This implies memory leaks when reading
1576 a new symbol table, until the conversion is finished. Did change
1577 (struct symbol) and (struct type) to be allocated on the
1578 symbol_obstack. Blocks and blockvectors are among the things
1581 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1582 tested much, but it solved one problem (reported by Meissner), and
1583 cleans up some other things. The problem happened when an
1584 included file contains actual code (functions) and not just
1585 definitions. The mips coff is a little inconvenient there, since
1586 it may cause a procedure to be mapped to the wrong psymtab.
1588 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1589 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1590 this will need work for the new core paradigm.
1592 Opcode patches from the net:
1594 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1595 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1596 missing altogether - they are added here. From Bruce Bauman.
1597 * mips-opcode.h: The low mask for C0 instructions was too small.
1598 From Garrett Lau. I modified the fix to check the entire 32-bit
1601 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1604 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1606 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1608 * dbxread.c (read_type): Pointer subtraction (value_sub in
1609 valarith.c) sometimes failed because the types of the
1610 pointers being subtracted were not identical.
1611 These differed because dbxread.c was allocating pointer types
1612 using dbx_alloc_type+smash_to_pointer_type instead of
1613 lookup_pointer_type. I failed to find a justification for the
1614 former, so I changed it to use the latter. Similarly, I
1615 replaced smash_to_function_type by lookup_function_type,
1616 and smash_to_reference_type by lookup_reference_type.
1618 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1619 _initialize_mipsread): corresponding changes.
1621 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1623 * source.c (mod_path): Do tilde_expand on each component of the path,
1624 rather than on the (list of) paths as a whole.
1625 (print_source_lines): Set first_line_listed in addition to
1626 current_source_symtab and current_source_line. If the source was
1627 not findable, after a "dir" command to fix the problem,
1628 a "list" would get the wrong lines.
1630 While I was there... (gnu):
1632 * dbxread.c (read_type): Change error to complaint.
1634 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1636 First attempt at detailed understanding of symbol table memory alloc.
1638 * dbxread.c (dbx_symfile_read): Free our string table if we
1639 aren't the mainline. Free the "info" struct since we're done with
1641 (init_psymbol_list): Free any previously allocated psymbol lists.
1642 (): FIXME: Should realloc-down the psymbol lists when done reading
1643 the main symbol file?
1645 * symmisc.c (free_symtab): Free fullname field too.
1647 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1648 (REGISTER_ADDR): Make result type unsigned int.
1650 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1651 define REGEX must also define REGEX1 (its dependency).
1653 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1655 * tconfig/i960: No longer works, points you at vxworks960 or
1658 * xgdb.c, XGDB-README: Remove file. Users can get the much
1660 * Makefile.dist: Remove all trace of xgdb.
1662 * breakpoint.c (breakpoint_1): Pass demangle arg to
1663 print_address_symbolic.
1664 (clear_breakpoints): Remove unused function.
1665 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1666 (breakpoint_re_set): Use catch_errors to do them all anyway.
1668 * gdb-int.texinfo (Host versus Target): Add section on what is
1669 a "host" feature versus what is a "target" feature.
1671 * infcmd.c (path_command, path_info): Handle the PATH variable
1672 (object search path) as conveniently as the source search path.
1673 * environ.c (set_in_environ): Set some vars in GDB's environment,
1674 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1675 * source.c (mod_path): New function, from guts of
1676 directory_command, modifies a path. Used by path_command.
1677 (directory_command): Call it.
1678 * defs.h (strsave): Declare.
1680 * utils.c (sevenbit_strings): Add new printing option.
1681 (printchar): Use it.
1682 (strsave): Provide this handy helper routine.
1683 (set_width_command): Rename set_screen_width_command.
1684 (_initialize_utils): "set screen-width" => "set width";
1685 "set screen-height" => "set height"; add sevenbit-strings.
1687 * infcmd.c (do_registers_info): Print floating point registers
1688 in raw hex as well as float format, regardless of whether it is
1689 a "virtual" convertible register.
1690 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1691 regs as a double, just in case it's being used that way.
1692 * values.c (unpack_long): Comment on array/function coercion.
1693 (unpack_double): Argument is in target byte order now. For
1694 integer arguments, just call unpack_long and float the result.
1695 * m68k-tdep.c: include defs.h for "const" handling.
1696 * remote-nindy.c: Use ieee-float stuff.
1697 (nindy_fetch_registers): Unpack double regs to host double, then
1699 (nindy_store_registers): Pack extendeds to host double, flip
1700 around by misusing unpack_double, send as target double.
1702 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1703 zero, as when stopped at the first instruction of a process.
1705 * blockframe.c: Fix filename in comment (param.h => tm.h).
1706 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1707 * tm-68k.h: Fix typos.
1709 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1711 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1713 * coredep.c (fetch_core_registers): Pass end-address of register
1714 section to register_addr as expected. Don't call supply_register
1715 if we'd just pass it garbage.
1717 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1719 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1721 * target.c (push_target, target_info): Cast enums to int for < or
1724 * stack.c (print_frame_info): Identify source file & line
1725 even if we can't print it.
1727 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1729 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1731 Clean up IEEE floating point support.
1733 * ieee-float.h: New file.
1734 * ieee-float.c: Write real routines to convert between host
1735 doubles and various target IEEE extendeds.
1736 * m68k-xdep.c: Eliminate assembler code for extended floats.
1737 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1738 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1739 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1740 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1741 double_to_ieee_extended.
1742 * i960-tdep.c: Define ext_format_i960.
1743 * m68k-tdep.c: Define ext_format_68881.
1744 * sparc-tdep.c: Define ext_format_sparc, though unused.
1745 * Makefile.dist (HFILES): Add ieee-float.h.
1746 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1749 Obsolete the "coffstrip" program in favor of using BFD's strip.
1751 * nindy-share/coffstrip.c: Remove file.
1752 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1753 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1754 * tconfig/nindy960: Remove reference to coffstrip.o.
1756 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1758 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1760 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1761 * dbxread.c: Remove static symfile_bfd.
1762 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1764 * inftarg.c (child_detach): Pop the child_ops vector if the
1765 detach is successful.
1766 * remote-nindy.c (nindy_create_inferior): Don't push a new
1767 nindy_ops since nindy uses the same one for execution and memory
1769 * core.c (core_ops): Use child_attach and child_create_inferior
1770 rather than default attach and create_inferior functions.
1772 Handle floating point registers in core files.
1774 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1775 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1776 This version untested since BFD doesn't yet support sun3 core
1778 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1779 conventions. Fix comments and style. This version has not
1780 been compiled yet, since we have no HP inhouse.
1781 * core.c (get_core_registers): Look for two sections, ".reg"
1782 and ".reg2", and pass both to fetch_core_registers sequentially.
1784 Revise directory path yet again.
1786 * source.c (forget_cached_source_info): Not static any more.
1787 (init_source_path): New default source path is "$cdir:$cwd".
1788 (dir_command): Handle variable arguments ($cdir, $cwd).
1789 (source_info): Print "Compilation directory" rather than
1790 "Originally compiled in" to remind people of $cdir.
1791 (openp): If the path contains $cwd, use current directory.
1792 (open_source_file): If compilation directory is known, replace
1793 first $cdir in path with the compilation directory.
1794 (print_source_lines): Even if we can't print the lines, set the
1795 current symtab and line for future commands like "info source" or
1796 "breakpoint". Also, error message now contains the file name,
1797 line number, and file access error message.
1798 (_initialize_source): Fix help text to describe changes.
1799 * main.c (cd_command): Forget cached source info when we chdir.
1800 * utils.c (strstr): Add simple implementation.
1802 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1804 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1805 Byte-swap COFF symbol tables if necessary when reading them in.
1806 Use complain() to replace error message in one spot. Needs
1807 corresponding change in bfd/coff-code.h to make some symbol
1808 swapping routines non-static.
1810 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1812 Merge changes from Eirik Fuller, for UTek.
1814 * defs.h (errno): Add declaration.
1815 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
1816 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1817 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1818 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
1819 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
1820 declarations of errno.
1822 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1824 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1825 <rpc/rpc.h> and <rpc/types.h>.
1827 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1829 * i960-tdep.c (examine_prologue): Add new argument limit,
1830 which stops the scan at the end of the prologue, or at the PC.
1831 This fixes a problem where it walks down into the code for the
1832 user's statements if that code looks like function prologues.
1833 Mark Fox and I have been bouncing this code back and forth, making
1834 small changes to it. Callers changed to match.
1836 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1838 Cleanup for gdb-3.94 release final:
1840 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1841 the .c files from vx-share and nindy-share, from the various
1842 macros, since they are not found via ALLDEPFILES.
1843 (SFILES): Add tm-i960.h.
1844 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1845 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1847 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1848 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
1850 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
1852 * am29k-tdep.c: Add contribution line.
1853 (examine_prologue): Cache information about function prologues in
1854 the misc-function-vector to avoid lots of references over the
1855 serial line while examining instructions.
1857 * core.c (core_close): New function made from cleanup_core.
1859 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1860 remote-vx.c, remote.c, target.c, target.h,
1861 Update target_ops vector to add attach, close, and load entries.
1862 Use add_syms_addr_command, not add_file_addr_command, for
1863 add_file. Break out close routine from existing code.
1865 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1866 they are in an obstack.
1867 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1869 (define_symbol): Add symbol type parameter; change callers;
1870 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1871 it to influence the symbol class on the i960.
1872 (define_symbol): Swap LOC_CONST's into target byte order.
1874 * exec.c (exec_close): New function.
1875 (exec_file_command): Call it.
1877 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1878 Fix byte order of frame pointer.
1879 (read_var_value): Result of 0 if var's value can't be found,
1880 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1881 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1882 (locate_var_value): Use read_var_value and use its lazy address
1883 as the location of the var's value. Lint.
1885 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1888 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1889 obsolete Intel versions in favor of vxgdb versions.
1890 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1891 code dealing with byte order of values, which Intel did in host byte
1892 order rather than gdb-4's target byte order.
1893 (i960_frame_chain_valid): Move to nindy-tdep.c.
1894 (examine_prologue, skip_prologue, frame_find_saved_regs,
1895 frame_args_address, leafproc_return, saved_pc_after_call,
1896 pop_frame): Add vxgdb versions from Mark Fox.
1897 (examine_prologue, frame_struct_result_address): Add code
1898 to deal with the saved value of G13 (struct return address
1900 (frame_args_address): Modify Mark's version to prefer the
1901 saved value over the current value in the topmost frame.
1902 Cache result in the frame info to avoid performance hair in
1904 (print_fault): Add gdb960 code for printing faults.
1905 (_initialize_i960): Actually call check_host.
1907 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1908 add stub routines. FIXME, these currently just return zero!
1910 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1911 (attach_command): Call target_attach, not target_open, now.
1913 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1914 (child_attach): Rename from child_open.
1915 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1916 don't confuse it with a zero step_resume_break_address.
1918 * inftarg.c (child_detach): Eliminate inferior_pid test.
1919 (child_files_info): Clean up message a bit.
1920 (child_ops): Use child_attach, not child_open, to attach.
1922 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1923 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1924 findvar.c to here, since it depends on the contents of the
1925 shadow_contents of breakpoints, but keep if #if 0 since it is
1928 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1931 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1932 (ptype_command, display_command): Eliminate have_inferior_p and
1933 have_core_file_p in favor of target_has_stack or
1934 target_has_execution.
1935 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1936 code for actually finding the values of arguments, though we still
1937 keep track of the maximum stack offset for use in printing unnamed
1938 arguments. Handle missing FRAME_ARGS_ADDRESS.
1940 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1941 (struct nindy_regs): Define registers passed to/from nindy.
1942 (nindy_fetch_registers, nindy_store-registers): Translate between
1943 nindy and GDB formats for the registers.
1944 (dcache_init): Statically allocate the cache, since it was being
1945 allocated by a malloc that was never freed anyway.
1946 (nindy_create_inferior): Error, not core dump, if no exec file.
1947 (nindy_before_main_loop): Use target_load, not target_add_file.
1949 * remote-vx.c (net_load): Specify large timeout for load
1950 requests. Allow user to break out with INTERRUPT.
1951 (net_break): Remove useless code, clean up. Change callers.
1952 (parse-args, skip_white_space, find_white_space): Clean up arg
1953 parsing to cope with quoted strings.
1954 (net_wait, net_quit): Never call error, just return status.
1955 (vx_read_register, vx_write_register): Cleanup status checking.
1956 #ifdef the code based on which CPU we are using (960 or 68k),
1957 FIXME, this should be completely general but it isn't yet.
1958 (vx_xfer_memory, vx_resume): Cleanup status checking.
1959 (vx_run_files_info): Improve message.
1960 (vx_load_command): Renamed from vx_add_file_command. Allow load
1962 (net_ptrace): Remove unused routine.
1963 (vx_wait): Adopt code from vxgdb960 to cope with broken
1964 connections to target machine and prompt to disconnect. Remove
1965 debug printouts. Map some EVENT_'s to SIGnals.
1966 (add_symbol_stub, vx_open): Print names of object files we found,
1967 and "ok" if we read their symbols OK. Clarify output in general.
1968 (vx_attach, vx_detach, vx_kill): Add these commands.
1969 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1970 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1971 "info files" output, and create_inferior, since we already have
1974 * stack.c (frame_info): Replace Frame_unknown with 0.
1975 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1976 (return_command): Pop until the PC matches as well as the FP,
1977 so it works even if the FP is shared with another function,
1978 as in "frameless" or "leaf" procedures.
1980 * symfile.c (load_command): renamed from add_file_target_command.
1981 (add_syms_addr_command): renamed from add_file_addr_command.
1982 (add_syms_command): Stub to call target_add_syms.
1983 (_initialize_symfile): Change command names and descriptions,
1984 add-file => add-syms, and load from alias to its own command.
1986 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1987 maybe_kill_then_create_inferior): Default for attempts to start
1988 a process, if one is already running, is to ask about killing
1989 it and retry if yes.
1990 (upstack_create_inferior): #if-0 it, strata obsolete it.
1991 (push_target, unpush_target, pop_target): to_close() a target
1992 before unstacking it.
1993 (target_info): Renamed from target_files_info.
1994 (_initialize_targets): Rename "i files" as "i target", accessible
1997 * target.h: Improve comments about the target_ vectored routines.
1999 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
2000 Convert commenting style to standard GNU style.
2001 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
2002 (SKIP_PROLOGUE): No longer a no-op.
2003 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
2004 (*_REGNUM): Sort register numbers.
2005 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
2006 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
2007 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
2008 are now 10 byte extendeds, not 8 byte doubles.
2009 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
2010 for nindy versus vxworks targets. FIXME, this should possibly go
2011 in the target vector.
2012 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
2013 frame_saved_regs and arg pointer with each frame.
2014 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
2015 (FRAME_ARGS_ADDRESS): Use cached result.
2016 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
2017 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
2018 (PRINT_RAMDON_SIGNAL): Call print_fault.
2019 (POP_FRAME): Now works.
2021 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
2022 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
2023 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
2024 (ADDITIONAL_OPTION_HANDLER): use target_load, not
2027 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
2028 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
2030 * valarith.c (value_subscripted_rvalue): Avoid handling
2031 floats and doubles specially; it gave alignment errors. Lint.
2033 * valops.c (value_of_variable, value_of_this): Error if unknown
2036 * valprint.c (print_floating): Bcopy rather than pointer-deref,
2037 to avoid alignment problems.
2038 (value_print): Handle unknown value address.
2039 (cplus_val_print): Two args are ignored; remove them. Change caller.
2040 (val_print): Use unpack_long rather than pointer-deref.
2043 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
2044 to avoid alignment problems.
2045 (value_being_returned): Error if return value unknown.
2046 (set_return_value): Add bogosity warning, FIXME. *
2048 * TODO: A woman's work is never done.
2050 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
2051 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
2052 Add ieee-float.o to OBS.
2053 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
2054 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
2055 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
2057 Changes to generalize the VxWorks RPC protocol slightly, to handle
2058 i960 as well as 68000.
2060 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
2061 * vx-share/reg.h: Produce i960 regs #ifdef I80960
2062 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
2063 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
2064 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
2065 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
2066 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
2067 so they will move in target byte order rather than network
2068 byte order (happens to be the same).
2070 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2072 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
2074 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2077 Add contribution lines to various files, showing where they
2080 * breakpoint.c (break_insn, check_break_insn_size,
2081 read_memory_nobpt): Remove to mem-break.c.
2083 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
2086 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
2087 entry has bad register number. This change is not
2088 tested in this release, FIXME.
2090 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
2093 * value.h: Force value's contents field to be aligned to hold
2094 at least a double or a long long (if supported). This avoids
2095 doing bcopy's in and out of the contents field.
2097 (step_1): Avoid coredump under obscure circumstances when we
2100 * symtab.h (misc_info): Add field to misc function vector for
2101 any kind of cached information the target code desires. AMD
2102 29000 uses this to avoid repeating examine_function_prologue's.
2104 * coffread.c: Lint. Remove static symfile, read_section_header.
2105 core.c (have_core_file_p): Lint: remove.
2106 expprint.c (print_subexp): Lint.
2107 infptrace.c, valops.c, valprint.c: lint.
2109 Roll in changes from vxgdb-5.0.1:
2111 * symtab.h: Comment byte order of each address class. Add
2112 LOC_LOCAL_ARG for frame-relative args (960).
2113 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
2114 symtab.c, symmisc.c: ditto.
2116 * infrun.c (init_wait_for_inferior): Clear stop_signal.
2118 * remote.c (remote_resume): Error if resume with a signal.
2120 * symfile.c (prim_record_misc_function): Clear misc_info.
2121 (fill_in_vptr_fieldno): Check stub type of arg.
2123 * valops.c (value_cast): Avoid looking up names of types whose
2124 name we don't know, to prevent coredump. Sun CC produces typedef
2125 rtx and the name of *rtx is zero...
2127 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2129 Roll in changes from final AMD 29000 port (Tiemann).
2131 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
2132 for ../include/a.out.encap.h. This might not work now that BFD
2133 is separately compiled. Instead, BFD support for encap will have
2134 to translate machine type 29k into the right COFF_MAGIC.
2136 * infcmd.c: Remove references to inferior_pid that aren't used
2137 in actual ptrace calls; use target_has_execution, etc.
2138 (have_inferior_p): Remove function.
2139 (program_info): Print target info rather than "process number";
2140 avoid gratuitous messages unless from_tty.
2141 (run_stack_dummy, finish_command): Set proceed_to_finish.
2142 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
2143 main.c: Lint. Lose have_inferior_p().
2144 inferior.h (have_inferior_p): Remove, lint.
2145 (proceed_to_finish): Add flag to ask that all regs be saved
2146 by normal_stop, for the few commands that need it, speeding up
2147 serial I/O. Add comments to stop_registers.
2149 * remote-eb.c: Remove newline from breakpoint message we grep
2150 for. Never time out when running the user program.
2154 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2156 Roll in changes from vxgdb-5.0.1:
2158 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
2159 symbol in its raw form, we are processing an unlinked ".o" file.
2160 See if the target environment has assigned it an address, using
2161 target_lookup_symbol (VxWorks does), and enter it into the symtab
2164 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
2165 68k versions for a simpler version that assumes zero FP at bottom.
2166 Fixes bug of truncated stack reports.
2168 * target.h (target_lookup_symbol): Define this routine's args
2169 and result, finally.
2171 * target.c (nosymbol): Default routine for target_lookup_symbol.
2172 (target_default): Default lookup_symbol and call_function too.
2173 (files_info): Only print has_all_memory warning if a non-dummy
2176 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
2177 vx_convert_from_virtual): If target does not have floating point,
2178 zero register "values", and avoid doing cross-net conversions.
2179 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
2180 (vx_open): Rearrange code that attaches to target and reads
2181 symbols for all loaded modules, to work if some of the modules
2182 are not accessible. Add symbol_stub() and add_symbol_stub()
2183 as callbacks from catch_errors(). Allow connect attempt to be
2184 interrupted painlessly with ^C (FIXME, there are still some bugs
2185 if the interrupt happens during symbol reading.). Print
2186 final message with puts_filtered, since symbol messages are
2191 * main.c (catch_errors): Only print errstring if non-null.
2192 (command_loop): Avoid an ioctl per command to test ISATTY.
2194 * remote-vx.c (net_load): make static; avoid sophomoric msg.
2195 (vx_xfer_memory): Return correct result!
2196 (vx_files_info): Indicate whether target has float or not.
2197 (vx_lookup_symbol): Complain, not error, if target gone.
2198 (vx_open): Print "Connected" msg before disabling immediate-quit.
2199 [FIXME: lookup_symbol and vx_open changes need testing.]
2201 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
2202 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
2203 contributor lines and update copyrights to 1991.
2205 Changes from an attempted H-PUX host port:
2207 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
2208 defines PT_ATTACH and PT_DETACH but not PT_KILL.
2209 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
2210 * remote-vx.c: include <sys/time.h> for HPUX.
2211 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
2212 "core_file_command" routine to BFD regime. May not work yet.
2214 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
2216 * xgdb.c: Replace X10 version with some VJ version.
2217 (FIXME: Its copyright assignment is not on record.)
2218 * xgdb.c: Update include files to X11R4 (Xaw crud).
2219 (xgdb_display_source, create_text_widget): fix call to
2220 get_filename_and_charpos. Rewack source window stuff for X11R4
2221 (gleaned from include files, and "nm's" of binary libraries, since
2222 I had no doc available).
2223 (append_selection, append_selection_word): Disable with FIXME
2224 since R4 changed interface here.
2225 (create_buttons): Add back the old set of buttons.
2226 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
2228 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
2229 Roll VERSION to 3.94 (not yet final though).
2231 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2233 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
2234 obstack_int_grow, obstack_int_grow_fast): Eliminate
2235 cast on left of assignment, which gives MIPS cc fits and is
2238 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
2239 F_ALIAS. Use printf, not fprintf, when not passing a file
2241 (compare_opcodes): Check that identical instructions have
2242 identical opcodes, complain otherwise.
2244 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
2245 was reported by Roland McGrath.
2246 (unimp): Only match if exactly zero instruction. (Roland)
2247 (branches and traps): Generate all variations of these
2248 instructions with macros, based on a single call that defines
2249 each condition name and its binary representation.
2250 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
2252 * valprint.c (val_print_fields): Take, and use, format parameter.
2253 This means that "p/x struct" again prints the elements in the
2254 desired format. Changed callers.
2256 * stack.c (frame_info): Use filtered output, and indicate wrap
2257 points. Remove kludgy formatting designed to avoid line wrap.
2259 * utils.c (wrap_here): If the line is already full (because
2260 we had printed a long indent or long wrapped string), do an
2261 immediate newline-and-indent.
2263 * m68k-pinsn.c (print_insn_arg): Bugfix from
2264 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
2265 instruction is incorrectly disassembled as bkpt #8.
2267 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
2268 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
2269 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
2270 and then will dump core (sometimes). I traced it back to an
2271 uninitialized symfile_name in psymtab_to_symtab.
2272 (const_vol_complaint): Add quotes to message.
2273 (define_symbol): Only believe line number if gcc_compiled.
2274 Avoid allocating symbol if we will not return it.
2276 Add target strata support so that newly established targets go
2277 into their right place in the target stack (e.g. a new exec file
2278 doesn't wipe out the ability to access the running process).
2280 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2281 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2282 and initialize it properly in all the targets.
2284 * target.h: Document strata. Change return type of push_target.
2286 * target.c (nomemory): new function for dummy memory access.
2287 (tcomplain): Rename complain, now also used in symfile.c.
2288 (push_target): Push targets within strata. New return value shows
2289 whether new target is on top of stack or not. Always keep dummy
2291 (target_files_info): Ignore dummy target.
2293 * core.c (core_open): Warn user, and skip accessing file, if the
2294 core target is not the topmost target in the stack.
2295 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2298 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2299 target_ops, it doesn't belong there since we have no regs there.
2300 Change name of target from machine => memory to clarify.
2302 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2304 * Freeze version 3.93 for release.
2306 * Makefile.dist: Handle vx-share and nindy-share subdirs
2307 properly when building gdb.tar.Z.
2309 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2310 printed in various places, so I could change just one copy.
2312 * dbxread.c, coffread.c: Change references to bfd->iostream
2313 to cast to FILE *, now that BFD avoids needing types defined
2314 in other header files.
2316 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2318 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2319 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2320 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2321 (actually gcc -Wall).
2323 * dbxread.c: Remove first_global_sym, last_global_sym, since
2324 they are never referenced.
2326 * defs.h (baud_rate): Declare.
2327 main.c: Define it, and add the -b option to set it.
2329 * gdb-int.texinfo: Add text on how to define a new host or target
2330 architecture, prompted by Per Bothner's questions about MIPS
2333 * gdb.texinfo: Document "complaints". Change doc of -q since
2334 gdb no longer prints the copyright and blurb if you specify a file
2335 name to be debugged (just like Emacs). Add doc for Nindy-specific
2336 command line flags for specifying target serial port and such.
2337 Update copyright to 1991.
2339 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2340 has taken over for us the job of ripping up executable files. The
2341 crud caused Per Bothner's port to not compile.
2343 * infrun.c (normal_stop): Avoid printing "Program exited
2344 normally" if we are in batch mode. This allows a GDB which
2345 executes a program on a target system, to behave like a Unix
2346 command (input from stdin, output to stdout, no extraneous
2349 * main.c (main): Allow additional machine-dependent command line
2350 options to be specified with the ADDITIONAL_OPTIONS,
2351 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2352 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2353 processing to occur just before the main loop with
2354 BEFORE_MAIN_LOOP_HOOK.
2355 (main): If a "core file" argument is specified, and it is not a
2356 core file, try it as a process ID to attach.
2357 (symbol_completion_function): Attempt to cope with
2358 "show screen-" TAB, not very successfully. This needs more work,
2360 (batch_file): New function, returns whether we are reading
2361 commands from an interactive tty on stdin, or from somewhere else.
2362 Called by normal_stop since it doesn't get from_tty passed down
2363 to it like many commands do.
2365 * remote-nindy.c: Handle command line options for nindy
2367 (nindy_before_main_loop): Prompt user for tty name if they
2368 don't specify it before getting to the interactive command loop.
2370 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2371 and -r command line options. Also add hook before main loop
2372 to make it easy to specify a tty.
2374 * TODO: More things to do, one done.
2376 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2378 * dbxread.c: Make complaint() calls pass pointer, not struct.
2379 Add complaints about badly formatted C++ type information
2380 (const/volatile indicator, and parse errors resulting in
2381 error_type). Fix C++ virtual member fn comment.
2382 (read_struct_type): Avoid bumping pointer if we got a parse
2383 error; this prevents our walking beyond the end of a string.
2384 Terminate loop on null char as well as semicolon.
2385 (process_one_symbol): Fix the LBRAC fix so that it uses the
2386 last previous SLINE, FUN, or SO record's PC address. C++ debug
2387 symbols did not have SLINE records in a useful order compared
2388 to the LBRAC records.
2389 (define_symbol): Handle "catch" records.
2391 * symtab.c (check_stub_type): Added new complain
2392 `stub_noname_complain' and added a consistency check to
2393 keep the debugger from crashing when finishing from an
2394 exception frame. A real fix will be needed later.
2396 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2398 * infcmd.c (attach_command): Make global.
2400 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2401 but make them easy to comment out. Perhaps later they should
2402 be enabled by what CPU you configure for? FIXME.
2403 (VERSION): Roll to 3.93.
2404 (pinsn.o): Remove rule for obsolete file.
2405 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2407 Run down a problem that manifested by printing the wrong function
2408 name in stack traces of read_ofile_symtab. Turned out that the
2409 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2410 the LBRAC symbol with an address in the *data* segment, which
2411 blew our binary search through the blocks.
2413 * dbxread.c: Use the complain() facility consistently to bitch
2414 about problems in the symbol file we are reading.
2415 (finish_block): Add code to check the nesting of the blocks;
2416 complain and Procrust them to fit if wrong.
2417 (make_blockvector): Check the order of the blocks, complain
2418 [but don't cope] if wrong.
2419 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2420 symbols to be sure their PC value is greater than the last SLINE
2421 (line number) symbol we've seen, complaining and adopting the
2422 SLINE PC value if wrong.
2424 * symfile.h (struct complaint, complaint_root, complain,
2425 clear_complaints): Add.
2426 * symfile.c (complain, complaint_root, clear_complaints): Add
2427 facility to deal with non-fatal complaints and to regularize their
2429 (symbol_file_add): Clear complaint counters to allow new complaints.
2430 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2432 * dbxread.c (dbx_symfile_read): Remember the address and size
2433 of the string table for the main symbol file, so we won't read it
2435 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2436 to avoid reading the string table yet again. Lint.
2437 (throughout): Improve filtered output, including word wrap.
2438 (read_range_type): Improve Bothner's fix to handle other types too.
2440 * utils.c: Improve line wrap implementation. Handle unlimited
2441 width by making chars_per_line unsigned.
2442 (puts_filtered): New, easy, function.
2444 * defs.h (puts_filtered): add.
2446 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2447 call the identical sort_symtab_syms() in symfile.c instead.
2449 * expread.y: Suggest the `file' command rather than `symbol-file'.
2451 * command.h (enum var_types): Add zinteger for seroable
2453 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2454 nested if's into a switch.
2456 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2457 we did not stop because of a breakpoint (it must have been for
2458 some other reason, like a "stepi"), so don't print anything.
2460 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2461 doesn't include <sys/types.h>, old SunOS's require it for
2464 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2466 A test port of gdb-3.92.6 to the Sony NEWS.
2469 Don't normally link in remote- or vx stuff.
2470 Some of it doesn't compile, and it wastes space for 99% of the users.
2471 Remove reference to no-longer-used HAVE_VPRINTF.
2472 Fixed BFD_DEP typo to BFD_DIR.
2474 Fix cast in arg to bfd_h_getlong.
2475 Make char *prefix be const.
2476 Fix how certain range types are mapped into builtin unsigned int types.
2478 Remove 2 #includes. They cause errors (on Sony, at least),
2479 and aren't needed (they wern't in earlier versions).
2481 print_address_symbolic should never demangle labels
2482 (since it prints *assembler-level* labels).
2484 [This was superseded by the change to printcmd below.]
2487 Add some "volatile" return types to avoid warnings.
2488 If MISSING_VPRINTF add vprintf function and not just macro
2489 (since vprintf is used in printcmd.c).
2491 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2492 (The latter isn't grokked by some PCC-based compilers.)
2494 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2496 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2497 * nindy-share/coffstrip.c
2498 Added some forward declarations (otherwise, gcc complains
2499 about implicit extern redefined as static).
2501 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2503 Changes inspired by Per Bothner:
2504 * printcmd.c (print_address_symbolic): Take additional parameter
2505 specifying whether to demangle.
2506 (print_address): Pass in asm_demangle to control demangling.
2507 (print_address_demangle): New fn, takes explicit arg to control
2509 * utils.c: Add new vars demangle and asm_demangle, and let them
2511 (fputs_demangled): If !demangle, just print the argument.
2512 (fprint_symbol): If !demangle, just print raw symbol.
2513 * valprint.c (val_print): Call print_address_demangle rather than
2514 print_address, to cause demangling to depend on the global
2515 rather than assembler-level demangling setting.
2516 * WHATS.NEW, gdb.texinfo: Document.
2518 * main.c (show_command): Show all settings if no arg.
2519 (initialize_main): Make "info set" the same as naked "show".
2520 * command.c (cmd_show_list): Handle prefix commands in the
2521 list, and print the name of the setting as well as its English
2522 description and value.
2524 Allow gdb functions to specify where a line should wrap if it
2525 exceeds the size of a terminal line. Use it to make the output
2527 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2528 of the right size when screen width changes.
2529 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2530 (wrap_here): New fn, indicates a point in the output where we
2531 should wrap the line rather than just letting it overflow at a
2533 (fputs_filtered): Implement wrapping.
2534 (n_spaces): New fn, returns a pointer to N spaces.
2535 (print_spaces_filtered): Use n_spaces.
2536 * defs.h (n_spaces): Declare.
2537 * stack.c (print_frame_info): Wrap with 4-space indent after
2538 fn name and before filename and line number.
2539 * printcmd.c (print_frame_args): Wrap with 4-space indent
2540 before each argument name is printed.
2541 * valprint.c (value_print): Wrap with no indentation before
2543 (val_print_fields): Wrap with indentation relative to nesting
2544 level before each field name.
2545 (val_print): Wrap with nesting indentation before array elements.
2546 * command.c (do_setshow_command): Avoid extra newlines,
2547 wrap with 4-space indent around values printed, end with period.
2548 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2550 * breakpoint.c (breakpoint_1): Implement addressprint for
2551 "info breakpoints" display. Change file name and line number
2552 format to " at file:nnn" rather than " (file line nnn)".
2553 * gdb.texinfo: Document.
2556 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2558 Frozen for gdb-3.92.6 release.
2560 README, WHATS.NEW: Update for 3.92.6 release.
2562 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2563 coffread.o from configs since it is now built by default.
2564 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2565 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2566 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2567 from configs since it is now built by default.
2569 Makefile.dist: Update for release 3.92.6. Handle files that
2570 have been moved to ../include, ../getopt, or ../bfd. Add
2571 saber.suppress and tests directory. Add config.status to
2572 the release (it will say "none").
2574 coredep.c: Minor formatting fixes.
2576 These changes were made in early December but only checked in now:
2577 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2578 nindy-share/nindy.c: lint
2579 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2580 register values coming back from the target; we store values
2581 in target byte order everywhere.
2583 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2585 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2587 * valprint.c (cplus_val_print, val_print_fields): New functions,
2588 which print C++ objects. They conspire to avoid printing a
2589 virtual base class more than once, following all the twists and
2590 turns of C++ virtual base rules.
2591 (val_print): Call the above rather than do it by hand.
2593 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2594 symbol file, not for added files like shared libs. This really
2595 needs to be generalized to a timestamp per file.
2597 * core.c (cleanup_core): Avoid coredump if no core file.
2599 * config.gdb: Accept -host or -target in place of +host or
2602 * coffread.c (find_linenos): Avoid desupported BFD interface
2603 to line numbers. We still read them manually rather than using
2604 BFD's "generic" features.
2606 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2608 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2610 * Makefile.dist: Eliminate use of $< in explicit targets.
2612 * readline/Makefile: Use $< rather than $*.c, which does not
2613 include the VPATH in GNU Make.
2615 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2616 copies of tconfig/i960, added for global configuration
2617 compatability. All i960 versions can read both coff and b.out.
2619 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2620 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2623 * TODO: Think of more things to do.
2625 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2627 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2628 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2629 64-bit float conversion.
2631 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2632 equivalent to sun?os4 so global config works.
2634 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2636 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2638 * main.c: Only declare linesize once; declare pagesize not at
2639 all, since it is never used.
2640 (main): Clear newly allocated line before it is used.
2642 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2644 Further stabilization for the Intel 960.
2646 * Makefile.dist: Parameterize the location of the "include"
2647 and "bfd" directories, as well as "getopt". Add symfile.c.
2648 Link in both dbxread and coffread. Fix up "make depend" to
2649 rewack the locations of include, bfd, and getopt in its output.
2651 * README: Document moving include files, improve some of
2654 * coffread.c: Move common code out to symfile.c. Change
2655 symbol_file_command style interface to use new *_symfile_init
2656 and *_symfile_read interface under BFD. Use BFD internal
2657 info to locate line table, symbols, etc.
2659 * core.c (core_fetch_registers): Rename to get_core_registers
2660 to avoid confusion with fetch_core_registers.
2661 (register_addr): Move to coredep.c, which is already machine
2662 dependent. This leaves core.c pretty clean of dependencies.
2664 * coredep.c (register_addr): Accept this routine from core.c.
2666 * dbxread.c: Move common code (with coffread.c, etc) into new
2667 symfile.c. Each psymtab now contains a pointer to the
2668 format-dependent function that knows how to read it in. Make
2670 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2671 (process_one_symbol): Add code to complain about a "compiler bug
2672 we muzzle here", if we actually see it.
2674 * eval.c (evaluate_subexp): Insert missing "break" statements
2675 in code that determines whether a variable is an lvalue in
2676 memory, register, or whatever. I detected this via a compiler
2677 bug in which it *almost* mashed out the whole switch statement.
2679 * gdb-int.texinfo: Add minor sections on configuring gdb for
2680 release, and about the README file.
2682 * infcmd.c (registers_info): Fix formatting somewhat. Still
2683 not as pretty as before, but it handles byte swapping.
2685 * remote-nindy.c: If data cache routines are interrupted while
2686 waiting for the remote end, be sure that any uninitialized cache
2687 blocks are on the free list, not on the valid list!
2689 * symfile.h: Flesh out this header file with all the various
2690 routines and variables that have been merged in from dbxread.c
2691 coffread.c, and symtab.c to symfile.c.
2693 * symfile.c: New file, containing code common to dbxread.c,
2694 coffread.c, and some code from symtab.c. All generic code for
2695 reading symbol files should be in here now.
2696 (unrecord_misc_function): Remove unused function.
2698 * symtab.h: Remove file-reading things to symfile.h.
2700 * symtab.c: Remove file-reading things to symfile.c.
2702 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2703 to decode i960 fault types.
2705 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2706 target.c: Change type of the "resume" function from int to void,
2707 since its result was never used.
2709 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2711 * main.c: Replace "stupid" with "caution"; you now "set caution
2714 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2716 * infcmd.c (do_registers_info): Call val_print to deal with the
2717 byte order of the registers being printed. FIXME, this makes
2718 the formatting of the output uglier.
2720 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2721 defined, call it for signals the debugger doesn't itself use.
2722 The i960 uses this for more detailed fault information.
2724 * remote.c (remote_open): If arg is null, print help rather than
2727 * sparc-xdep.c (register_valid): Avoid declaring size, since
2728 various modules will think of various sizes depending on the
2729 architecture of their tm-file. FIXME, we need protection against
2730 actually entering one of those modules, which would clobber
2731 storage if not for the target architecture compiled into gdb.
2733 * stack.c (up_command, down_command): Always print the frame
2735 (up_silently_command, down_silently_command): New commands
2738 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2740 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2741 more parameters than it used to.
2743 * findvar.c (registers): Increase slop to 256 bytes, which should
2744 protect us against even most RISC machines with large register
2746 (locate_var_value): Move declaration inside related ifdef.
2748 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2749 throughout, to avoid throwing away buffered input from the board.
2750 (nindy_wait): Supply_register takes addr_of_value, not value.
2751 (i960_print_fault): Renamed from i80960_fault.
2752 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2753 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2755 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2756 we can set the PC in the call to proceed(). Unpush nindy_ops
2757 before pushing it on top, to avoid message to user. Eliminate
2758 commentary from Unix machines that just misleads here.
2759 (reset_command): Fix error message to suggest target command.
2761 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2763 Release 3.92.5 as frozen.
2765 Stabilize the merged release...with help from lint, Saber C,
2768 Everywhere: Add include files needed to declare return types
2769 of functions called.
2771 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2773 * breakpoint.h: Add undeclared breakpoint functions, and some
2774 functions for display handling since I couldn't think of a better
2777 * breakpoint.c (insert_breakpoints): Make code for disabling
2778 shared library bkpts more likely to work. It's used when we
2779 rerun a program and stop before the shared library has been
2781 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2782 cast from pointer, so it squeezes through catch_errors.
2783 (bpstat_stop_status): Fix logic broken some time ago. We now
2784 always create a bpstat if the stop address matches a breakpoint,
2785 even if we don't stop there -- just like the old code used to do
2786 before I got my fingers into it (sigh).
2787 (breakpoint_1): Print "ignore count" after "stop only if"
2788 condition, since that's how it actually works.
2789 (mention): Handle watchpoints as well as breakpoints.
2790 (watch_command): use set_raw_breakpoint and mention to do most
2791 of the work (and initialize all the fields!). Only pass one
2792 arg to parse_c_expression, since that's all it takes.
2794 * command.c (not_just_help_class_command): Rename arg to args
2795 since we ignore "unused argument" warnings on vars named "args".
2796 inflow.c (child_terminal_info): ditto.
2797 infptrace.c (kill_inferior): ditto
2798 main.c (catch_errors, version_info, quit_command, pwd_command,
2799 source_command, dump_me_command, editing_info,
2800 set_history_size_command, set_history, show_history,
2802 stack.c (locals_info): ditto
2803 target.c (target_files_info): ditto
2804 valprint.c (set_input_radix, set_output_radix): ditto
2806 * core.c: Remove old variables for handling core and exec file
2807 sections (data_start, data_end, stack_start, stack_end,
2808 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2809 text_end, exec_data_start, exec_data_end, text_offset,
2810 exec_data_offset, data_offset, stack_offset). They're
2811 superseded the more general build_section_table and
2813 (get_exec_file): Mention the `file' command.
2814 (read_memory_check): Rename to memory_error, and only call it
2815 in the case of an actual error.
2816 (read_memory, write_memory): call memory_error.
2817 (core_fetch_registers): Register section name is ".reg".
2819 coredep.c: Remove a bunch of crud now that all this file does
2820 is pull the registers out of a core file.
2821 (fetch_core_registers): Rewrite to actually work, I hope.
2823 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2824 Replace index() with strchr(). Remove all the pre-BFD macro
2825 definitions for accessing the symbol file.
2826 (struct dbx_symfile_info): Encapsulate the information that
2827 dbx_symfile_init needs to pass to dbx_symfile_read in this
2830 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2831 dbx_symfile_discard): Rearrange symbol file reading to divide
2832 the format-specific part from the format-independent part,
2833 leaving the format-independent part such as file name expansion
2834 and opening in symtab.c. This replaces
2835 partial_symbol_file_open and partial_symbol_file_read.
2836 Symbol_file_read, add_file, add_file_target_command,
2837 add_file_addr_command move to symtab.c. Pass an explicit
2838 "mainline" flag for when reading the main symbol table, rather
2839 than relying on the offset address to be zero or nonzero.
2841 (dbx_symfile_read): Don't allow void *'s to be printed as
2843 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2844 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2845 macro" debug version really work.
2846 (read_dbx_symtab): Remove unref'd parameter inclink.
2847 Avoid swapping N_SLINE symbols, for speed.
2848 Merge N_TEXT!N_EXT case with the other external symbol
2849 definitions' case. Add comments.
2850 (start_psymtab): Allocate the symfile name in the psymtab on
2851 the psymbol_obstack, rather than using the caller's storage.
2852 (end_psymtab): Only allocate a dependencies list if there are
2854 (psymtab_to_symtab_2): Use BFD when reopening file to read
2855 its symbols for real.
2856 (read_struct_type): Add FIXME comments where it needs work
2858 (read_huge_number): Add FIXME about overflows.
2859 (read_range_type): Add FIXME about comparing a long to 1<<32.
2861 * coffread.c: Minor changes to move things closer to the new
2862 regime with symtab.c and dbxread.c Major work is still needed
2865 * exec.c (exec_file_command): Remove old variables (see core.c
2867 (xfer_memory): If memory transfer is right at the end of a
2868 section, don't lose.
2870 * findvar.c (get_saved_register): If value is in a real
2871 register, LVAL is lval_register, not lval_memory.
2873 frame.h: Declare print_sel_frame and record_selected_frame.
2875 gdb-int.texinfo: New file, for GDB internals documentation.
2876 Very simple, unformatted doc of cleanups is there for now.
2878 gdbcore.h: Remove obsolete variables that described a.out
2879 section addresses and offsets. (See core.c above.)
2880 Declare fetch_core_registers and registers_fetched.
2882 getopt.c: Declare char *alloca(); even on SPARC.
2884 infcmd.c (run_command): Call target_kill rather than
2886 (step_command, next_command, stepi_command, nexti_command):
2887 Declare from_tty parameter even though we don't use it.
2888 (run_stack_dummy): argument BUFFER is a char array, not
2889 a pointer to REGISTER_TYPE.
2890 (finish_command): using_struct_return needed a value *,
2891 not a struct symbol *.
2893 * infptrace.c (child_xfer_memory): To avoid dependency on
2894 where sections are in memory, try PT_WRITE_D and if that fails,
2895 try PT_WRITE_I. Most Unixes don't care which you use.
2897 * infrun.c (step_resume_break_shadow): Change to array to
2898 match other breakpoint shadow storage.
2899 (clear_proceed_status): Pass address of bpstat to
2900 bpstat_clear, not the bpstat itself.
2901 (child_create_inferior): FIXME comment about if the child
2903 (start_inferior): Remove old function.
2904 (child_open): Use target_kill rather than kill_inferior.
2905 (wait_for_inferior): Ditto.
2906 (insert_step_breakpoint, remote_step_breakpoint): Use
2907 new step_resume_break_shadow.
2909 * inftarg.c (child_wait): If all child processes die,
2910 pretend that the one being waited for exited with signal 42.
2912 * main.c (command_line_input): When scanning for comments,
2913 don't coredump on unclosed quotes.
2914 (quit_command): Use target_kill rther than kill_inferior.
2915 (_initialize_main): Rename class_user from "user" to
2918 * printcmd.c (print_command_1): Initialize "fmt" if no format
2919 is specified by the user.
2920 (print_frame_args): Only add to args_printed if we are
2921 actually fetching args from the stack (avoiding undefined
2923 (_initialize_printcmd): Remove bogus \{ from string.
2925 * remote-eb.c (eb_open): Avoid coredump on no argument.
2927 * remote-nindy.c: Bring out of Intel environment into new
2928 target environment. Remove all conditional compilation on
2929 I80960. Massive hacking throughout.
2930 (nindy_xfer_inferior_memory): New routine stolen from
2932 (nindy_create_inferior): New routine pieced together, probably
2933 not quite working yet.
2934 (nindy_ops): New target_ops struct for nindy.
2936 * remote-vx.c: Use write_memory rather than target_write_memory
2937 to get error checking.
2938 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2940 (vx_create_inferior): Use target_terminal_ours...
2942 * signame.c (_initialize_signame): Always initialize, since
2943 we need the table for things other than psignal.
2945 * solib.c (solib_add): Use symbol_file_add, not add_file.
2946 (solib_address): Return boolean result rather than struct
2947 pointer which nobody else knows the type of.
2949 * sparc-tdep.c, valops.c: Use write_memory rather than
2950 target_write_memory, to get error checking.
2952 * stack.c (locals_info, catch_info, args_info,
2953 get_selected_block, frame_command, up_command): Use
2954 target_has_stack, rather than have_inferior_p or
2957 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2959 * symfile.h: New file, defining the interface between the
2960 generic and object-file-specific symbol reading code.
2962 * symtab.c: Move generic symbol-reading interface to symtab.c,
2963 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2964 table to map BFD targets to symbol-reading modules in GDB.
2965 Change index to strchr.
2966 (lookup_struct_elt_type): Use error() rather than hand-made
2967 simulations thereof.
2968 (lookup_partial_symbol): Speedup slightly when length == 0.
2969 (symbol_file_add): New function.
2970 (symbol_file_command): Call it.
2971 (symfile_open, symfile_init): New function.
2972 (add_file_target_command, add_file_addr_command): moved from
2975 * target.c (target_command): use target_kill.
2977 * target.h (target_files_info): Don't declare, never called
2980 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2981 files to determine stack end address.
2983 * valarith.c (value_x_binop, value_x_unop): Change error message
2984 to be more useful. Pass proper argument to value_struct_elt.
2986 * valops.c (value_assign): FIXME comment that long long
2987 bitfields will break here.
2989 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2990 Update `make saber_gdb' to work better.
2992 * TODO: A woman's work is never done.
2994 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2995 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2996 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2997 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2998 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2999 valops.c, valprint.c, exec.c: Lint.
3002 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
3004 Continuing Intel 960 port merge of GDB.
3006 * Makefile.dist: Merge i960 "nindy-share" files. Rename
3007 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
3008 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
3009 Wack over "make depend" so it handles files in subdirectories
3010 vx-share, nindy-share, bfd, and in the current directory.
3012 * blockframe.c (get_prev_frame_info): Remove fatal error
3013 if stack not defined.
3015 * core.c (core_open, core_detach): New functions that handle
3016 the old "core-file" command as "target core" and "detach" instead.
3017 (core_file_command): Call them.
3018 (core_xfer_memory): Use common routine xfer_memory.
3020 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
3021 dbxread now uses bfd for everything but symbol reading itself.
3022 BFD internals are used to drag out the relevant file offsets.
3023 (partial_symbol_file_open): Change args all around for BFD.
3025 * symtab.c: Rename "value" to "val" everywhere, so we can
3027 (symbol_file_command): New command, moved from dbxread.c
3028 and coffread.c. It uses BFD to read the file, then vectors
3029 based on its type, to dbx or coff symbol readers.
3030 * symtab.h: Extern a few vars for symbol_file_command.
3032 * target.h: Breakpoint takes a char * save area, not a char **.
3034 * valprint.c (val_print): When unpacking bitfields, offset
3035 the address in gdb of the value, if it is declared with a shorter
3036 type. Remove the last "runtime kludge test" of host byte order.
3038 * utils.c: Remove old my_bfd_read routine.
3040 * stack.c (frame_info): Use target_has_stack. Print program counter
3041 register's actual name rather than "pc", since it's called the
3042 "ip" (instruction pointer) on the i960 (sigh).
3044 * target.c (target_command): Add command for selecting a target
3045 type and calling its open routine. This is used for initiating
3046 communication with a particular target, in a generic way.
3048 * tm-i960.h: Update for modern gdb. Remove semicolons from
3049 various macros. Handle reading struct return convention, and
3050 error-out attempts to return structs with the "return" command.
3051 Be sure gdb doesn't think we know how to call functions in the
3054 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
3055 to i960_xxx in lower case.
3056 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
3057 not being defined yet.
3059 * remote.c (remote_open): Call start_remote to initialize
3060 wait_for_inferior during open.
3061 (remote_xfer_inferior_memory): Return length written rather
3064 * remote-vx.c (target_command -> vx_open): Use new generic
3066 * remote-eb.c, inftarg.c, exec.c: ditto.
3068 * infrun.c: Fix comments.
3069 (attach_program -> child_open): Use new generic target command.
3070 (wait_for_inferior): Clear saved register values before target_wait,
3071 so target_wait can set some of them if convenient.
3073 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
3074 Return success indicator, not void.
3075 (child_xfer_memory): Avoid fetching initial word if we'll
3076 overwrite it anyway.
3078 * infcmd.c (attach_command): Use new generic target open routine.
3079 (_initialize_infcmd): Update doc on attach and detach commands.
3080 (do_registers_info): Merge in a byte-order problem as a FIXME
3083 * findvar.c (find_saved_register): Avoid problem in current frame.
3084 (read_relative_register): Ditto.
3085 (write_register): Convert byte order on the way out.
3087 * exec.c (file_command): Add.
3088 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
3089 (xfer_memory): Common function between core_xfer_memory and
3091 (exec_xfer_memory): Use it.
3093 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
3095 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
3096 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
3097 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
3099 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
3101 Merge Intel 960 port of gdb, continuing...
3103 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
3104 symbol_file_command): Pass from_tty arg to hush 'em up.
3106 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
3107 Add magic numbers for 960 COFF format.
3109 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
3111 Merge Intel 960 port of gdb, from Intel "1.2" release.
3113 CHANGE_LOG entries from their port, which was based on
3116 Thu Sep 6 11:02:22 PDT 1990
3117 Remove temp file if download is interrupted.
3119 Wed Aug 1 09:08:33 PDT 1990
3120 Now uses binary protocol to talk to NINDY.
3121 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
3122 Times out after 5 seconds when trying to talk to NINDY.
3124 Tue May 29 12:54:49 PDT 1990
3125 Added variable baud rate (-b switch).
3126 Source code reorganization.
3128 Thu Apr 26 11:09:55 PDT 1990
3129 More cleanup of batch mode; specifically, execute "-s", "-e", and
3130 "-se" switches as soon as they are encountered on the invocation line.
3132 Fri Apr 20 13:47:15 PDT 1990
3135 Thu Apr 19 09:54:28 PDT 1990
3136 Add 'reset' command.
3138 Wed Apr 18 09:48:07 PDT 1990
3139 After opening remote tty, wait for 1 second to go by without input
3140 from it before trying to talk to NINDY (fixes problems with the
3141 Heurikon HK80/V960E).
3143 Mon Apr 4 16:33:05 PDT 1990
3144 Some output was not being suppressed in 'batch' mode.
3146 Thu Mar 22 15:31:11 PST 1990
3147 Ask user if old symbol table should be deleted when new file is
3150 Allow user to run a program downloaded before gdb960 was brought up.
3152 Correct "exec-file" help message for i80960 context.
3154 Correct bug in calculating user space address: could occasionally
3155 corrupt user program.
3157 Make sure to zero low-order bits in rip's because of bug in 960CA
3158 A-step part: could cause operation faults when "next"ing across
3161 Correct bug that made it impossible to get source line numbers for
3162 code loaded at addresses higher than 0x7fffffff.
3164 Wed Jan 10 12:43:22 PST 1990
3165 Open remote tty for exclusive use.
3167 Fri Jan 5 12:14:42 PST 1990
3168 Correct disassembly (CA manual was right after all):
3169 opcode for sysctl is 0x659
3171 Mon Oct 23 12:03:04 PDT 1989
3172 Use G960BASE and G960BIN environment variables to find 'sx' utility.
3174 Mon Oct 16 14:15:09 PDT 1989
3175 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
3177 Mon Oct 2 15:56:31 PDT 1989
3179 Added 960CA disassembly support.
3181 To simplify maintenance:
3182 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
3184 - eliminated opcode.h: incorporates tables into i960-pinsn.c
3185 - moved 960-specific routines from i960-pinsn.c to i960-md.c
3186 - made disassembly interface identical to that in gdmp960.
3190 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
3192 * target.h: Allow targets to stack. Add target_has_memory,
3193 _registers, etc. Restructure memory access and "info files"
3194 to walk the target stack.
3195 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
3196 target.c: Change tables to match target.h.
3197 * inflow.c (child_mourn_inferior): pop child_ops.
3198 (generic_mourn_inferior): Use new has_stack flag.
3199 * infptrace.c (child_xfer_memory): New memory regime.
3200 * inftarg.c (child_files_info): New "info files" regime.
3201 * remote-eb.c: New memory regime, new info files.
3202 * remote-vx.c: New memory regime, new info files. Now use
3203 separate targets for VxWorks attachment to machine, and
3204 actually running a process under VxWorks, since one has
3205 stack & execution & regs and the other doesn't.
3206 * remote.c: New memory regime, new info files.
3207 * sparc-xdep.c (fetch_core-registers): New memory regime.
3208 * target.c: New routines and support for stacked targets,
3209 new memory regime, new info files regime.
3212 Generalize section handling for an arbitrary number of sections,
3213 including use of the new BFD (binary file) library.
3214 * gdbcore.h: Add struct section_table.
3215 * exec.c (build_section_table): Iterate all sections and
3216 record what gdb needs to know about them.
3217 (exec_command): Use it.
3218 (exec_xfer_memory): Use the table.
3219 (exec_files_info): Print the table.
3220 * core.c (core_file_command, core_xfer_memory, core_files_info):
3222 * source.c (find_source_lines): Use bfd_get_mtime.
3223 * dbxread.c: Quick changes to make it compile with new BFD.
3224 * utils.c (error): Avoid using bfd_error in generic routines.
3226 * core.c (core_fetch_registers): Get from the ".regs" section of
3228 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
3230 * inferior.h (attach_flag): Export.
3231 * infcmd.c (run_command): use new target_create_inferior.
3232 * infrun.c (child_create_inferior): Don't return result.
3233 * Makefile.dist (VERSION): 3.91.4.
3235 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
3237 * breakpoint.c (bpstat_num): Handle breakpoints which have
3238 since been deleted, such as temporary breakpoints.
3239 infcmd.c (program_info): ditto.
3241 * core.c (core_file_command): Display the frame where the core
3246 * remote-vx.c (target_command): Merge in target command from
3247 targ-vx.c. A few other cleanups.
3249 * TODO, Projects: Lots more stuff to do...
3251 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
3253 Massive changes to wall off the remote-debugging interface
3254 behind a function vector. The port to handle VxWorks targets
3255 is also part of this.
3257 All files: Replace references to renamed functions,
3258 remove references to remote_debugging, remove references to
3259 have_include_file, have_core_file in favor of target_has_stack,
3260 target_has_memory, etc.
3262 * Modularize the breakpoint interface.
3263 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
3264 a breakpoint instruction.
3265 breakpoint.c: struct breakpoint's shadow_contents now sized as
3267 (insert_breakpoints): Vector to target to install breakpoints.
3268 (remove_breakpoints): Vector to target here too.
3269 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
3270 sparc-tdep.c (single_step): Use new breakpoint interface for
3271 the single-step breakpoints.
3272 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
3273 New file, contains routines to insert and remove breakpoints by
3274 reading out the old contents and later replacing them. This is
3275 how ptrace breakpoints work, and many remote systems as well.
3277 * tm-vxworks68.h: New config file, overrides a few things for
3278 Wind River's preferences.
3280 * target.h: New file, for transfer vector used to talk to the
3281 inferior (child, attached, core, exec, remote, etc). All accesses
3282 to the thing being debugged should come through these vectors.
3283 target.c: New file, routines to handle transfer vector.
3284 (various files): Add transfer vectors XXX_ops for the various
3285 targets and pseudo-targets (core files, etc) we support.
3287 * breakpoint.c (bpstat_stop_status): Further explorations of
3288 watchpoints and why things don't work all the time.
3289 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3291 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3292 the local gdbinit if it doesn't already have it.
3294 * core.c (core_ops): add and install.
3295 Allow core debugging without exec file.
3297 * dbxread.c (free_and_init_header_files): Merge two fns.
3298 (end_symtab): Free named symbol table when a new version comes in.
3299 (read_dbx_symtab): Relocate all kinds of symbols with base
3300 address. First step toward handling different text, data, bss
3302 (add_file_addr_command): Renamed add_file_command.
3303 (add_file_command): Vector to remote handler.
3304 Add "load" as an alias for "add-file" command.
3306 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3307 non-returning functions.
3309 * exec.c: Add exec_ops, and push it as a target when an exec
3312 * infcmd.c (run_command): Pass executable file name and arg list
3313 separately when starting an inferior. Permit "run" when no exec
3314 file is specified, for VxWorks.
3315 (detach_command): Move to child_detach in inftarg.c.
3317 * inftarg.c: New file. Unix-child-specific routines, and the
3318 child_ops structure.
3320 * inferior.h (registers): Export "registers" as the way for
3321 target dependent register handlers to find gdb's local copy of
3322 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3323 since it is now used by places that want wait_for_inferior to
3324 handle the grunge but want to see every trap from the inferior.
3326 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3327 Eliminate remote_debugging hooks in terminal handling.
3329 * infrun.c: Replace start_inferior with child_create_inferior.
3330 Move all the hair of Unix shells and ptrace idiosyncracies into
3331 child_create_inferior, so remote handlers don't have to deal.
3332 Remove running_in_shell. Rename stop_after_attach to
3333 stop_soon_quietly, and use it in a few other places where we want
3334 to just call wait_for_inferior and get control back on the first
3335 trap. trap_expected now never takes a value > 1.
3336 (init_wait_for_inferior): Initialize static vars when a new
3339 main.c (gdbinit): Add new hook for .gdbinit file name, let
3340 it be overridden by config files as GDBINIT_FILENAME.
3341 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3342 Both of these are used for VxWorks gdb.
3344 mcheck.c: rename include file "gmalloc.c" to avoid problems
3345 with system include file "malloc.c".
3347 param-no-tm.h: New include file, same as param.h but does not
3348 include the default "tm.h" file. This is used in files where
3349 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3351 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3353 remote-vx.c: New file, VxWorks remote debugging support. Uses
3354 RPC routines that are shared with the target system, in directory
3357 remote.c: Vectorize remote interface.
3359 source.c: Globalize source_path, and make an alias "l" for "list"
3360 since we now have the "load" command.
3362 sparc-xdep.c: Use new param-no-tm.h.
3364 symmisc.c (free_named_symtab): Add new function from Wind River.
3365 However, ifdef it out for now while we think about what it should
3368 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3370 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3371 non-Unix-children handle this with their own code in the target
3374 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3375 source and target lists. Add vx-share to default list of include
3376 directories. Add new files to src and target lists: mem-break,
3377 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3378 ${srcdir} versions of munch and createtags are used.
3380 * valops.c (find_function_addr): Split out of call_function.
3381 (call_function_by_hand): Rename call_function; this function
3382 calls functions in the target by laboriously patching the target
3383 word-by-word with the right stack, args, regs, etc.
3386 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3388 Handle AMD 29000 a bit better.
3390 * remote-eb.c (readchar): Mask received char log to make it readable.
3391 (remote_start): Pass arguments down to executing program.
3392 Make startaddr unsigned.
3393 infrun.c (start_inferior): Accept args, pass them to
3395 infcmd.c (run_command): Pass args down to start_inferior.
3397 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3398 the target object file format.
3399 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3401 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3402 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3404 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3406 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3407 * TODO: We did a few things, we have more to do though.
3409 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3410 * inflow.c (inferior_died): Clear deferred stores.
3412 * Debug problems with dummy frames and calls to the inferior.
3413 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
3414 * sparc-tdep.c (do_restore_insn): Simplify.
3415 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3416 (sparc_push_dummy_frame): Simplify and fix what we push.
3417 (sparc_pop_frame): Slightly more hair here, deciding whether
3418 we are restoring a saved PC or returning to a return address in %i7.
3419 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3421 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3422 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3423 * obstack.h (chunkfun): ditto.
3424 * defs.h (xmalloc, xrealloc): ditto
3426 * utils.c (quit): Grab the terminal from the child if necessary.
3428 * inflow.c (term_status_command): Rename to term_info, change
3431 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3432 (is_delayed_branch): Speed up.
3433 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3434 Still missing some float ops, and needs testing.
3436 * Support for input and output radixes other than base 10
3437 * defs.h (input_radix, output_radix): Declare.
3438 * expread.y (yyparse, parse_number): Handle changes of input
3439 radix, and ambiguous names-or-numbers in radixes >10.
3440 * printcmd.c (print_scalar_formatted): Print formatted hex
3441 numbers in varying column widths.
3442 * valprint.c (val_print): Use output_format to print scalar ints.
3443 (set_input_radix, set_output_radix, set_radix): Create.
3444 (set_output_radix): Set output_format from output_radix.
3445 (_initialize_valprint): add `set radix' but leave the others off.
3447 * main.c (execute_command): Let stupid questions be turned off.
3448 (_initialize_main): Handle "set stupidity", etc.
3450 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3451 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3453 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3455 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3456 bfd stuff is still screwed up, but with some manual work, it
3459 * breakpoint.c (bpstat_do_actions): Start over if a command
3460 proceeds the inferior, since the inferior will have stopped and
3461 will need to have its new stop-actions taken care of.
3463 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3464 compiler fits, simplify it.
3466 * gdb.texinfo (directory command): Doc new dir command.
3467 source.c (directory_command): "dir" now puts things on the front
3468 of the path, moves dups up front, and handles multiple names
3469 on the command line, inserting each one in order. It also
3470 blows away cached line and full_filename info.
3472 * stack.c (backtrace_command): Skip "more stack frames follow"
3475 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3476 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3477 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3478 The only odd one was Gould NP1, which had defined vprintf to
3481 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3482 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3483 variable, inspect_it.
3484 valprint.c (print_string, val_print): Use the global inspect_it
3485 to indicate whether to print in Epoch style or normal style.
3487 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3489 * printcmd.c (call_command): add an alias for the "print" command
3490 which runs expressions and doesn't print the result if void.
3491 (print_command_1): implement it.
3493 * command.c: Remove #if 0'd code. Initialize all the fields
3494 in add_cmd (). Rename do_nothing_command to
3495 not_just_help_class_command, and make it externally visible.
3496 command.h: add user_commands to struct.
3497 * main.c (define_command): Don't overload c->function with a char
3498 string as well as a function pointer.
3500 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3501 calling convention of value_struct_elt () that got dropped in
3504 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3505 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3507 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3509 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3510 until a good time (e.g. when we are about to run the child),
3511 saving ptrace calls.
3512 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3513 * tm-sparc.h: define DO_DEFERRED_STORES.
3515 * sparc-xdep.c (store_inferior_registers): when storing float
3516 registers, don't store stack regs too. When storing the SP,
3517 however, DO store the stack regs too. This fixes a bug in which
3518 the dummy frame is not recognized when a call_function finishes,
3519 because its frame pointer (in the stack regs) was never
3521 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3522 even though we don't know how to read them from an inferior.
3523 valops.c (call_function): Comment about storing SP.
3525 * infrun.c (save_inferior_status): Save away the original bpstat
3526 chain so it can be restored later. Install the copied version for
3527 use by whoever saved the status. It will be blow away by
3528 restore_inferior_status, and the original chain restored. This is
3529 important for people who have pointers into the original.
3531 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3532 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3533 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3536 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3538 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3539 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3540 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3542 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3544 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3545 Store the baseclasses in a type struct starting from array element
3546 0 rather than from the unusual array element 1.
3548 dbxread.c: the above.
3549 (virtual_context): Add
3550 Read new debug information about which virtual function table
3551 a virtual function is from, and store it in fn_field.fcontext.
3553 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3554 TYPE_FN_FIELD_STATIC_P.
3556 symtab.c: the above.
3557 valops.c: the above. Handle pointer casts of object *'s.
3558 (search_struct_method): Add.
3559 (value_struct_elt): First arg is now a pointer to a value, and is
3562 valprint.c: the above.
3563 values.c (value_virtual_fn_field): Add type arg. Handle
3564 offsetting to the proper object when calling virtual fns.
3566 (baseclass_addr): Add valuep arg.
3568 * README: Document the current state of BFD config (missing).
3569 * TODO, ChangeLog, Makefile.dist: Roll version.
3570 * WHATS.NEW: Add summary of changes since 3.5.
3572 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3574 * dbxread.c (read_struct_type): Clear bit vectors whenever
3576 symtab.c (B_CLRALL): define.
3578 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3579 using == rather than =. Huh... This fixes the dreaded problem
3580 wherein builtin_type_int becomes TYPE_CODE_FLT.
3582 * core.c (info_files): Show the inferior pid.
3584 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3585 already knows how to look in the source directory.
3587 * Remove psymtab hair from many places. Remove duplicated code
3588 for searching symbol tables. Hide psymtabs from most places.
3589 Make it fast to get from a psymtab to its symtab.
3591 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3592 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3593 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3594 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3595 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3596 new symtab completely. New psymtabs get symtab pointer
3597 initialized to zero. Remove MI warning printf.
3598 symtab.h: Comments. Add psymtab to symtab pointer.
3599 (PSYMTAB_TO_SYMTAB): New macro.
3600 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3601 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3603 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3605 (print_frame_info): Avoid special-casing symbols that have not yet
3608 * source.c (open_source_file): Quick path if we have already
3609 located the source file by its full name.
3611 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3612 find_pc_psymtab. When a name is found in the misc function
3613 vector, search the symbol table for its mangled name, not the
3614 name that the user typed.
3616 * bfd.h: Fix missing comment terminators, make #endifs match.
3618 * valarith.c (value_less): Handle unsigned int comparisons.
3619 Add FIXME about pointer compares, which assume host and target
3620 pointers are the same.
3622 * command.c (do_nothing_command): lint
3623 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3624 fix comments on debug symbol format for visibility. Actually set
3625 visibility of symbols.
3626 main.c (echo_command): lint; use <readline/history.h>.
3627 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3628 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3629 pointing past end of allocated memory; saber complains.
3630 obstack.h: Declare the external functions that we use.
3631 valarith.h: use <string.h>
3632 solib.c (solib_add): lint.
3634 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3636 * main.c (initialize_main): Default info_verbose to off, now that
3637 symbol reading is fast.
3638 (quit_command): Avoid clobbering exec_bfd while quitting.
3640 * Initial BFD (binary file diddling library) merger:
3641 coffread.c: Change AOUTHDR to struct exe_hdr.
3643 core.c: initialize initialized data at compile time.
3644 (core_file_command): Move from coredep.c, convert to bfd.
3645 (xfer_core_file): Convert to bfd.
3646 exec.c (exec_file_command): use bfd routines.
3648 mips-tdep.c: Remove exec_file_command and friends.
3651 * coredep.c: (fetch_core_registers) Convert core_file_command to
3652 fetch_core_registers.
3653 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3655 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3656 (my_bfd_read): More bogosity, which I don't think we call.
3657 (program_name): Remove this atrocity asap!
3659 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3662 values.c: allocate_repeat_value was not clearing the
3663 optimized_out field.
3664 (value_static_field): minor stylistic fix (wrong macro was used).
3665 valops.c (value_struct_elt_for_address): didn't work for C++
3668 * signame.c (_initialize_signame): Initialize signal names once.
3670 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3671 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3672 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3674 * remote-eb.c: Support user-settable baud rates on the serial port.
3676 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3678 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3680 * tconfig/sun3os4: Remove warning about native assembler,
3681 since it also occurs in the xconfig file.
3683 * findvar.c (registers): Allocate some slop after `registers'
3684 to prevent stray accesses from trashing the next variable.
3686 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3687 on the sun-3, by changing the #ifdef from `sun3' (which is not
3688 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3689 vars, which happened to follow `registers' in the executable.
3691 * readline/history.c (history_search): Heed gcc-2's advice
3692 and parenthesize && inside ||).
3694 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3695 tm-29k.c: Insert FSF copyright headers.
3697 * remote-eb.c: Better comments.
3699 * Makefile.dist: Update to 3.91.6.
3700 * TODO: note PREPARE_TO_STORE problem.
3702 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3704 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3706 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3708 * infrun.c (wait_for_inferior, at end): Don't set up
3709 prev_* if the inferior no longer exists.
3711 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3712 CANNOT_EXECUTE_STACK.
3713 valops.c (call_function): Use it.
3715 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3717 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3718 infrun.c (wait_for_inferior, 2 places): Use it.
3720 * values.c (value_being_returned): Only use
3721 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3723 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3724 right thing for remote-eb.c.
3726 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3727 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3729 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3730 (FRAME_FIND_SAVED_REGS).
3732 * findvar.c ({fetch,store}_registers): Check for
3733 REMOTE_{FETCH_STORE}_REGISTER macro.
3735 * findvar.c (get_saved_register): Add argument lval and
3736 change meaning of argument addr.
3737 findvar.c: Change calls to get_saved_register to reflect
3738 new calling convention.
3739 valops.c (value_assign): Use get_saved_register instead of
3740 find_saved_register.
3742 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3744 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3745 an (uninitialized) pointer to one. Use "&" when passing it
3748 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3750 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3753 * coffread.c (symbol_file_command): Put semicolon after
3755 Put safe_to_init_tdesc_context in #if defined (TDESC).
3756 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3757 coffread.c: #include <sys/stat.h>.
3758 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3759 Add missing ')' in check for "lc%" and friends. Remove
3761 Declare read_one_sym() at top of file.
3762 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3763 MC68WRMAGIC can have the same value without causing a duplicate
3766 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3768 * Allow a Makefile to be built without building the
3769 tm and xm file links that screw up builds in subdirectories.
3770 This is done with `config.gdb none', then you can do things
3771 like `make gdb.tar.Z'.
3772 * tconfig/none: Config file for no target system
3773 * xconfig/none: Config file for no host system
3774 * config.gdb: If no TM or XM files are called out by the
3775 host or target file, don't make links for them.
3777 * cplus-dem.c: Add documentation.
3779 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3780 simple error, so the user's gdb doesn't crash due to some object
3781 file problem (e.g. somebody is rebuilding the file out from under
3784 * printcmd.c (print_address_symbolic): demangle the symbol.
3786 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3787 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3788 (alldeps.mak): sort and uniq all results from this; duplicates
3789 hose gdb.tar.Z link building. Remove RCS files from
3790 tconfig and xconfig. Add config files for sun386. Add
3791 a few odd files to OTHERS and HFILES.
3793 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3795 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3796 Roll version number to 3.91.5. Make lint work in bindir.
3798 * README: Document cross-debugging and new file structure.
3800 * blockframe.c: Lint. Include "value.h" to declare read_register.
3801 (find_pc_partial_function): remove duplicate line.
3803 * command.h: Lint. Declare error_no_arg and dont_repeat.
3805 * tm-news.h: Remove inadvertently duplicated stuff.
3807 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3808 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3810 * config.gdb: Allow `config.gdb host target' form. Clean
3811 up previous change that printed bogus messages when you just said
3814 * core.c: #include "command.h" for lint.
3817 * main.c: Remove some casts of enums. Lint.
3824 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3826 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3827 read it from memory. This will allow us to save ptrace calls
3828 eventually. Changed caller single_step too.
3830 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3831 that we aren't going to use, saving many ptrace calls, especially
3832 when watchpointing or single stepping. Use some #define's for
3834 (store_inferior_registers): Ditto.
3835 (core_file_command): Use some #define's for constants.
3837 * tm-sparc.h: Add #define's for some register numbers, so we
3838 can eliminate the use of random constants in sparc-xdep.c.
3840 * stack.c (frame_command, print_frame_info, up_command,
3841 down_command) Remove frame_changed, since it
3842 causes a bug and doesn't seem to do anything useful. In some
3843 places it was used as a flag, in others as a stack level (?).
3845 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3846 default is to use the portable (vprintf) version rather than the
3848 * xm-news.h (MISSING_VPRINTF): Add.
3850 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3852 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3854 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3855 about linking debugged programs -Bstatic in the sun?os4 config
3856 files in tconfig and xconfig subdirectories.
3858 * main.c (main): Remove unreached exit(0) now that we exit
3861 * Create TODO file for online bug list. There are too many
3862 "little" bugs to keep track of on paper.
3864 * Change Projects file to refer to bug-gdb@cygnus.com
3865 rather than kingdon@ai.
3867 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3869 * Makefile.dist (VERSION): 3.91.4 now.
3871 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3872 (condense_misc_bunches): Add sanity check that misc_count is
3873 the same as the number of symbols in the bunch.
3875 * coffread.c: rename init_misc_bunches. Pass an argument
3876 to condense_misc_bunches (a zero).
3878 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3879 every time we are called; don't rely on our caller to do it.
3880 (add_file): Remove call to init_misc_bunches.
3882 * mipsread.c: Only warn, don't error, if unknown symbol types.
3883 This keeps an old gdb from falling on its face if it sees newly
3884 extended symbol info. Rename init_misc_bunches.
3886 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3888 * Merge in changes from Per Bothner for DECstations and other
3889 MIPS stuff. The rest is Bothner speaking:
3891 The next message is a merger of Alessando Forin's mips port with
3892 mine. I've tried to use my good if biased judgment to get
3893 the best of both. It *does* need testing.
3895 Some of the changes are general, *not* mips-specific.
3898 Didn't believe in little-endian bit order.
3899 There are still inconsistencies about whether flags
3900 like BITS_BIG_ENDIAN are integer (#if ...) or
3901 boolean (#ifdef ...). I tried to paper over them.
3903 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3904 Moved some misc_function code that was common to
3905 {dbx,coff,mips}read.c to symtab.c.
3906 In the process, I think I cleaned things up a bit.
3907 At the same time, moved obsavestring and obconcat to symtab.c.
3910 Removed obsolete condense_addl_misc_bunches (use
3911 condense_misc_bunches(1) instead).
3914 Needed to include <sys/dir>, at least on DECstations.
3916 valops.c, mips-tdep.c, tm-mips.h:
3917 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3918 conventions (when STACK_ALIGN is insufficient).
3919 Needed on mips, where doubles need 8-byte alignment,
3920 but ints only need 4.
3923 Removed cruft that was not being used.
3924 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3927 Print $ before register-names (I think that makes things a little
3929 Never print two instructions, even if one delays.
3930 Removed hex-disassemble set_cmd. (This is not mips-specific,
3931 so I think the argument is whether it is generally worthwhile or not.
3932 I'm inclined to think not, given how easy it is to
3933 convert between radixes in gdb.)
3936 This is basically Alessando's code.
3937 It doesn't use obstacks; I changed it to use obstacks
3938 in a few minor places where using malloc causes a
3939 memory leak. (Probably, more places could/should be changed.)
3940 I added record_misc_function where it was missing.
3941 In symbol_file_command and add_file_command, I tried
3942 to make the code consistent with more recent versions.
3943 Minor sylistic changes in parse_procedure.
3944 Make a .gdbinfo. psuedo-symbol point back to the real
3945 procedure symbol (using the isym field).
3948 This is basically from my port, but with a lot of details
3949 and a number of routines merged in from Alessando's version.
3950 I basically used my code "raw" backtrace (use heuristics
3951 from the actual code, rather than symbol table info) - though
3952 the idea is Alessandro's. I feel my code is a little cleaner
3953 here, particularly in being a little more flexible, such as being
3954 able to handle gcc-produced code (which it now can).
3955 It also doesn't do frame caching (which is not useful
3956 more recent gdb versions).
3957 I also used my code for push_/pop_dummy, more or less.
3958 I tried to incorporate AF's code for testing sigtramp
3959 while backtracing; I probably got it wrong.
3960 Added mips_print_register, which tries to scrunch as much
3961 information as possible on a screen...
3962 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3963 under mips-pinsn.c), I don't see anything mips-specific here,
3964 and I don't see it being all that useful anyway.
3967 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3968 Use more register names (rather than hard-cases numbers).
3970 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3972 * Hack up 3.90.11 changes:
3974 * Makefile.dist (depend): parameterize $(GCC).
3975 Add solib.c and solib.o.
3976 (readline): Fix vpath for both absolute or relative SRCDIR.
3978 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3979 Also, let the part I didn't understand at least compile so
3980 I can test the rest. FIXME.
3982 * dbxread.c: Fix thinko using strcmp.
3983 (init_psymbol_list): declare static.
3984 (partial_symbol_file_open): Comment cleanups better, avoid
3985 cleaning up the string table since the caller will do that.
3986 Move the stat for mod time into symbol_file_command, temporarily.
3987 (There should be a mod time for each symbol file, eventually,
3988 to control its rereading. FIXME.)
3990 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3991 SunOS, which gives error for shared libs otherwise. (From
3992 Schaefer, probably FIXME needs work for portability.)
3994 * solib.c: Move #include "param.h" to work.
3995 Lowercase all the Uppercase Letters In the Messages.
3996 (find_solib): Clean up inferior_so_name for debug printouts.
3997 Allow no argument, to mean all shared libraries.
3999 * symmisc.c: include param.h to get CLEAR_SOLIB.
4001 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
4003 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
4004 to 3.90.11. ChangeLog entries below are from this.
4006 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)

4012 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4016 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
4018 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
4020 * sparc-opcode.h Added single-operand version of rett.
4022 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4024 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
4025 Put parens around gcc_p in expansion.
4027 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4029 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
4031 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4033 * Changes for Sun shared libraries:
4034 blockframe.c (find_pc_partial_function): If a non-text symbol
4035 is found, set *address = pc - FUNCTION_START_OFFSET.
4036 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
4037 Disable breakpoints instead of giving an error.
4038 source.c (select_source_symtab): Initialize cs_pst.
4039 symmisc.c: Call CLEAR_SOLIB if defined.
4040 symtab.h: Make text{low,high} CORE_ADDR not int.
4041 (psymtab): New field addr.
4043 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
4044 (record_misc_function): Give correct type for N_DATA symbols.
4045 (condense_misc_bunches): do "misc_function_count = j" regardless
4047 Take code which is shared between symbol_file_command and
4048 add_file_command and put it into partial_symbol_file_{open,read}.
4049 Split add_file_command into add_file_command and add_file.
4050 Make psymtab_to_symtab read in the string table if the file
4052 Two new parameters to read_dbx_symtab and start_psymtab.
4053 tm-sunos.h: New file.
4055 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4057 * infcmd.c: Change cont_command to continue_command and "cont"
4060 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4062 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
4064 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
4066 * values.c (USE_STRUCT_CONVENTION): Check for structures of
4067 size 1,2,4,8 rather than size < 8.
4069 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
4070 as necessary, not just once.
4072 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
4074 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4076 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
4078 * tm-news.h: Add CALL_DUMMY_*.
4080 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
4082 * config.gdb: In list_host, list_target, use ${i}, not $i.
4084 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4086 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
4088 * sparc-opcode.h: Change all store floating-point state register
4089 instructions to have the right match & lose fields.
4091 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4093 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
4095 config.gdb: If srcdir != ., create readline directory and
4096 copy a makefile into it.
4098 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
4099 consistency with POSIX.
4101 * breakpoint.c (bpstat_stop_status): Disable watchpoint
4102 when we exit its exp_valid_block.
4104 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
4106 * Makefile.dist: Bump version to 3.91.3.
4108 * Clean up handling of breakpoint commands (somewhat).
4109 Prompted by Tiemann bug report "cont 10" doesn't work any more.
4111 inferior.h: Add breakpoint_proceeded to inferior status struct
4112 and globals; save it and restore it.
4113 (clear_breakpoint_commands): Cleanup, remove old #define.
4115 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
4116 (save_inferior_status, restore_inferior_status): handle it also.
4117 (proceed): Remove earlier code that set breakpoint_proceeded.
4118 It is now set only in clear_proceed_status.
4119 (clear_proceed_status): Cleanup, use bpstat_clear rather
4120 than clear_breakpoint_commands. No callers need the stop_bpstat
4121 between clear_proceed_status and proceed.
4123 infcmd.c: Add breakpoint_proceeded definition and comment.
4124 (cont_command, jump_command, signal_command): Move call to
4125 clear_proceed_status right next to call to proceed.
4127 breakpoint.c (bpstat_do_actions): Avoid clobbering our
4128 caller's argument while running down the chain of breakpoints.
4129 Use new variable "breakpoint_proceeded" to determine when
4130 a command that it executes moves the inferior past the
4132 (bpstat_clear): Handle NULL argument.
4133 (bpstat_clear_actions): Avoid useless call to
4134 breakpoint_auto_delete.
4135 (delete_breakpoint): Clean up bpstat's that are pointing to
4136 the deleted breakpoint from the stop_bpstat chain.
4137 (breakpoint_auto_delete): Simplify.
4139 * Clean up handling of EOF, error on stdin, etc. This was
4140 prompted by a network problem that caused gdb to go into an
4141 infinite loop filling up its malloc'd memory.
4143 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
4144 not clear_breakpoints_commands, which is now gone.
4145 (main): If command_loop returns (e.g. from EOF on stdin), do
4146 a quit_command (looping back to command_loop if quit_command
4147 doesn't really quit).
4148 (command_loop): check result from command_line_input and
4149 exit if it returns NULL, rather than passing the NULL to
4151 (gdb_readline): Free malloc'd result space before returning
4154 * utils.c (query): Handle C-d to mean "yes", just as if the
4155 input was not a terminal. Also avoid infinite loop if EOF
4156 occurs in mid-input-line before newline. This allows
4157 query to be used at EOF on stdin with reasonable results.
4159 * infrun.c (proceed): Set breakpoint_proceeded.
4161 * values.c (value_as_long): Avoid infinite recursion for enums.
4162 (_initialize_values): Fix typo in help msg (kingdon).
4164 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
4165 RL_LIB for linking. This allows -lreadline for linking
4166 and nothing for dependencies, once readline is a real library.
4168 * config.gdb: Jim Kingdon: give useful error message if the
4169 host or target type is not recognized.
4171 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
4172 it just defines it. Dumb, but deal with it.
4174 * Jim Kingdon suggests:
4175 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
4177 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
4179 * Makefile.dist (VERSION): Bump version # to 3.91.2.
4181 * Clean up Bothner's changes.
4183 * blockframe.c (clear_pc_function_cache): New function.
4184 * blockframe.c: remake cache_pc_function_* static.
4185 * dbxread.c (symbol_file_command): remove references to
4186 cache_pc_function_* variables.
4187 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
4188 * printcmd.c: Avoid kludging a global variable (addressprint)
4189 to avoid printing the address of a string twice. Instead,
4190 pass the format letter 's' down low enough that it can be seen
4191 to avoid this problem.
4192 (print_formatted): Pass format arg to value_print.
4193 (restore_addressprint): Remove function.
4194 (do_examine): Avoid hacking addressprint, cleanups and such.
4195 (print_frame_args): Add a comment to a Bothner change.
4196 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
4197 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
4198 to wipe out the values cached in blockframe.c.
4199 * symtab.c (find_method): Add comment saying how big you must
4200 allocate to be "big enough". Per being terse again.
4201 * valprint.c (val_print): Handle format letter "s" to print
4202 strings without addresses. Add comment to vtbl printing code
4203 which casts with wild abandon. Rearrange reference-printing
4205 @0xaddr: value (print w/addressprint)
4206 value (print w/~addressprint)
4207 @0xaddr (parameter lists w/addressprint)
4208 or nothing (parameter lists w/o addressprint)
4210 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
4212 * Merge more changes from Per Bothner:
4214 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
4215 annoying) that I tried to improve it. Here are my suggestions.
4217 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
4220 Do automatic de-reference when taking the address of a reference.
4222 Don't deref_ref when printing parameter lists.
4224 More attempts at treating refernences properly.
4226 In val_print, if deref_ref==0, don't print dangling " = ".
4228 Add COERCE_REF macro, which de-references an REF.
4230 * Merge changes from Per Bothner:
4232 * Fixed (Sony news)-specific configuration problems.
4233 * Fixed other problems with using vanilla pcc and libc (enum problems;
4234 assumption that vsprintf exists).
4235 * Some major speed-ups (finc_pc_partial_function now caches a match;
4236 parsing avoids duplicate symbol_lookup calls).
4237 * Changed handling of baseclasses (no longer use baseclasses field
4238 of struct type, use the first n_baseclasses fields instead).
4239 * Various minor changes/fixes, most C++-related.
4242 Cache the most previous match from find_pc_partial_function.
4243 (Save both low and high ends of matching function's pc range.)
4244 This speeds up the loop of infrun.c:wait_for_inferior quite
4245 a bit, and makes step/next commands much zippier.
4247 Added an enum->int cast (otherwise, some compilers barf).
4249 No longer set baseclass offset to 0, since multiple
4250 inheritance now mostly works.
4251 Added a number of casts, to shut up compiler warnings
4252 (after stabs where made enums, not ints).
4253 When discarding a symbol table (in symbol_file_command),
4254 must clear the cache introduced in blockframe.c.
4255 Don't convert $vtbl_ptr_type to vtbl any more.
4256 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
4257 Mask off sign bit emitted by g++ for virtual table offset.
4258 Set voffset to -1 (not 1) for static member functions.
4260 Changed parsing/lexing of names to avoid doing symbol lookup twice
4261 (once when lexing to determine symbol class, once for real).
4262 Now only call symbol_lookup once. Fields of 'this' win especially big.
4264 Subpress printing addr twice in the case of 'x/s addr'.
4266 lookup_basetype_type is no longer used.
4267 Add find_methods as recursive helper function to decode_line_1.
4268 This allows multiple inheritance to work.
4269 Also, once one or more matches has been found, do not look in
4270 base-classes. (Baseclass methods would be overridden, anyway.)
4272 Removed baseclasses array in struct type.
4273 Instead of using baseclasses[i], use fields[i-1].
4274 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
4275 Changed sign convention of voffset (previous was inconsistent).
4277 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4279 Used to assume existence of vsprintf. Re-written to not need it
4280 if HAVE_VPRINTF is undefined.
4282 typecmp was too pessimistic. Made it less so.
4284 Don't print space after address.
4285 If vtable points to a misc symbol (with 0 offset), print it,
4286 since that indicates the actual class of the object.
4287 Changed ype_print_derivation_info to use new inheritance
4288 scheme (without baseclasses vector).
4290 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4291 Also, changes needed because TYPE_BASECLASSES were removed.
4293 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4295 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4298 If there is no path set, and the symbols don't indicate what directory
4299 a file was compiled in, look in the current directory. But either
4300 a path or a known compilation directory will prevent this.
4303 Three independent bug fixes:
4304 * Remove the #if 0 block that breaks some stuff.
4305 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4306 adapt gdb to either SunOS 4.0.* or 4.1.
4307 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4310 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4313 (type_print) Demangle the name being printed.
4314 (type_print_base) Handle botched demangling without coredump (tiemann).
4317 (check_stub_method): Document routine.
4318 (tiemann) fix bug for no-arg functions
4319 Avoid clobbering beyond end of malloc'd storage.
4320 Terminate the argument list properly.
4322 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4324 * Changes merged by John Gilmore:
4327 In breakpoint_1, use new print_address_symbolic instead
4328 of find_pc_partial_function. (This forces use of assembler-level
4329 addresses, and avoids misleading non-mangled source-level names.)
4331 Generalize ansi argument such that -1 means skip arglist totally.
4332 Removed global variable print_ansi_qualifiers (which made
4333 code non-reentrant), in favor of extra explicit arguments
4334 to internal routines.
4336 Add new helper function print_address_symbolic.
4337 Use find_pc_misc_function instead of find_pc_partial_function
4338 (since we want assembler-level symbols here).
4340 Print unknown function as just "f (...)", not "f (...) (...)".
4341 Use new fputs_demangled explicitly.
4343 Fixed a typing violation (problem: value.h cannot be imported
4344 without renaming many variable in this file).
4345 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4346 decode_line_1: Moved forward some never-reached code.
4347 Made decode_line_2 skip function prologues correctly.
4349 fputs_filtered should not demangle by default.
4350 Add new fputs_demangled to demangle on demand..
4352 Change value_struct_elt to use value_primitive_field (using recursive
4353 utility function search_struct_field). This allows foo.bar to work
4354 for multiple inheritance (so far only for data fields).
4355 Change check_field in the same way (recursive helper function
4356 to support multiple inheritance).
4357 (Note: there are more of these problems that I haven't fixed.
4358 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4359 value_of_this: 'this' symbol name is now just "this", note "$this".
4361 Don't print static members.
4362 Avoid printing "members of <type>" if there are none.
4363 Simplified type_print_derivation_info by merging duplicate code.
4364 Remove useless blank lines in type_print_base (ptype command).
4366 Added declaration of new routine value_primitive_field.
4368 Added value_primitive_field which is generalized version of
4369 value_field that can handle multiple inheritance (non-zero offsets etc).
4370 Re-implemented value_field to call value_primitive_field.
4372 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
4374 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4375 delete the whole environment. Karl Berry reported the bug.
4376 * source.c - fix openp to avoid //'s in filenames, which
4377 trigger an Emacs bug causing it to not be able to find files
4378 when running gdb in a window.
4379 * dbxread.c - zap the #if 0 that botches the add-file code.
4380 It seems to work a lot better without all the code commented out.
4382 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
4384 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
4387 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
4389 * Makefile - added a ${CFLAGS} to a couple of entries,
4390 added remote-sa.sparc.c
4391 * added remote.sa-sparc.c, a modification of remote.c
4392 which conducts a dialog directly with the SparcStation prom.
4393 * breakpoint.c, infrun.c, sparcdep.c added
4394 remote_insert_breakpoint(), and remote_remove_breakpoint()
4395 to breakpoint.c instead of directly writing breakpoint instructions.
4396 * sparcdep.c on remote_debugging,there is no need
4397 to remove signle step breakpoint instructions.
4398 * main.c added "-epoch" flag and "int epoch_interface" to main.c
4400 * printcmd.c - epoch interface sends lisp expressions to open up
4401 epoch windows on inspection.
4402 * valprint.c - added arrayprint, and addressprint and made adding
4403 format controls easier
4404 * wait.h added a couple of undef's because we were getting
4405 complaints about WSTOPSIG and WTERMSIG begin redefined.
4408 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
4410 * symtab.c (decode_line_1): Add support for handling method stubs
4411 in the type information.
4413 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
4415 * values.c (baseclass_addr): Run loop from INDEX+1 to
4416 N_BASECLASSES; otherwise, we can still get into a loop.
4417 @@ This should be restructured to use a cleaner search strategy.
4419 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
4421 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
4422 abbreviation "Tt" for tags which have the same name as their
4425 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
4427 * symtab.c (list_symbols): add ability to set breakpoints on all
4428 the functions which match a particular regular expression.
4430 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
4432 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
4433 should print ANSI qualifiers (such as `const' and `volatile').
4434 All callers changed to call with ANSI == 1, except from
4435 `check_method_stub', which uses old-style syntax.
4437 * symseg.h (struct fn_field): Remove unneccessary `args' field.
4438 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
4440 * values.c (check_stub_method): New function.
4442 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
4444 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
4445 * valprint (type_print_base): Ditto.
4447 * symtab.c (gdb_mangle_typename): New function.
4449 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
4451 * breakpoint.c (catch_command): New function. Provides a
4452 mechanism to set breakpoints based on catch clauses.
4453 (disable_catch): Similar, but disables breakpoints on catch
4455 (delete_catch): Similar, but deleted breakpoints on catch clauses.
4457 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
4459 * blockframe.c (blockvector_for_pc): New function.
4460 * blockframe.c (block_for_pc): Changed to call
4461 `blockvector_for_pc' and get the block itself.
4463 * stack.c (catch_info): New function. Prints info about
4464 exceptions which can be caught in the current frame.
4465 * stack.c (print_frame_label_vars): New function. Similar to
4466 `print_frame_local_vars'.
4467 * stack.c (print_block_frame_labels): Prints out labels that are
4468 defined in this frame. These labels are exceptions that can be
4471 * dbxread.c: Updated to handle N_CATCH symtab types.
4473 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
4475 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
4476 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
4477 when printing the type.
4479 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
4481 * valprint.c (val_print): Use `baseclass_addr' to access the
4482 baseclasses pointed to via the derived class object at VALADDR.
4484 * values.c (baseclass_addr): New function. Casts derived pointers
4485 to baseclass pointers taking virtual baseclasses and multiple
4486 inheritance into account.
4488 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4492 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4494 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
4495 exp_valid_block field correctly.
4497 * infrun.c (wait_for_inferior): When checking "don't even think
4498 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
4499 also check step_resume_breakpoint.
4500 Insert breakpoints and continue (not step) if
4501 step_resume_break_address != NULL, even if another_trap.
4502 If trap_expected and we enter sigtramp, then set up a
