5 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
7 * dbxread.c (read_struct_type): Grok anon structs for C++.
8 (vb_name, vptr_name): Null terminate these strings.
10 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
12 Minor bug fixes from BSD Net2 gdb:
14 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
15 returns 0, there is no previous frame.
16 * breakpoint.c (commands_command): If !from_tty, don't call
17 input_from_terminal_p().
18 * dbxread.c (record_misc_function): Speed up slightly.
19 (compare_psymbols): Ditto.
20 * infcmd.c (do_registers_info): Take a second argument to
21 determine whether to print float registers. "info registers"
22 does not do so anymore. "info all-registers" does, now.
23 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
25 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
26 * inflow.c (initialize_inflow): Set tflags_ours correctly.
30 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
31 executing_breakpoint_commands if we are interrupted by error.
32 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
33 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
34 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
35 catch_errors() so we can setup the frame regardless of whether
37 * ieee-float.c (double_to_ieee_extended): Get exponent from
38 right place in little-endian systems. From John Carey.
40 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
42 * main.c: Remove unused terminating_signals and catch_termination().
43 (long_options): Terminate with a zero element.
44 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
45 (gdb_readline): Make call-compatible with readline.
46 (init_signals): Improve comments re vfork vs. signal.
48 * utils.c (prompt_for_continue): Use new gdb_readline().
49 If we prompt for continuation, we don't let CR repeat the previous
50 command, once we get back to a prompt. It's too easy to keep
51 hitting CR, expecting "--more--" prompts, and have some long
52 command start repeating on you.
54 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
56 * blockframe.c (frameless_look_for_prologue): Speed up by
57 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
58 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
59 Define two variants, one faster.
60 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
61 and return zero, rather than giving an error.
62 (setup_arbitrary_frame): Initialize the PC in the new frame.
63 (skip_prologue): Add a second arg saying whether we're just
64 checking for a frameless function or not.
66 * core.c (core_open, core_close, core_xfer_memory): Move
67 section table pointers and bfd* into the target_ops.
68 (core_open): Allow errors in shared lib reading, etc.
69 (core_files_info): Describe shared library sections.
71 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
72 exec_files_info, set_section_command): Move section table
73 pointers and bfd* into the target_ops.
74 (add_to_section_table): Add BFD to section table.
76 * target.c (target_xfer_memory, target_info): Pass target to
77 xfer_memory and target_info functions.
80 * gdbcore.h: Move struct section_table.
81 * target.h: New home of struct section_table.
83 * solib.c (solib_add): New argument is the target_ops whose
84 section list is to be added to, if any. Reallocate the
85 sections in that target to add any that come from shared libs.
86 (throughout) so_sections renamed to sections.
87 (solib_xfer_memory): Deleted.
88 * tm-sunos.h (SOLIB_ADD): Add target argument.
89 (SOLIB_XFER_MEMORY): Delete.
91 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
92 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
93 from target_ops. It's the same on all targets. Add two section
94 pointers to target_ops.
96 * stack.c (find_relative_frame): Dump ancient algorithm for
97 "down", just use handy "next" pointers.
98 (frame_command): Don't error if there is no stack; let user
101 * inflow.c (new_tty_prefork, new_tty): New prefork routine
102 modifies static state in the parent process; new_tty itself
103 runs in the child and modifies the child's file descriptors
104 to match the saved static state.
105 * infrun.c (child_create_inferior): Call new_tty_prefork,
108 * infptrace.c (child_xfer_memory): Add ignored target arg.
109 * remote-eb.c (eb_xfer_inferior_memory): ''
110 * remote-nindy.c (nindy_xfer_inferior_memory): ''
111 * remote-vx.c (vx_xfer_memory): ''
112 * remote.c (remote_xfer_memory): ''. Rename from
113 remote_xfer_inferior_memory.
115 * main.c (main): Only try to attach "corefile" argument if
116 it starts with a digit.
118 * symfile.c (symbol_reloading): New "set/show" variable.
119 (symbol_file_add): Shorten message about symbol reading.
120 (add_symbol_file_command): Merge with add_syms_addr_command,
121 since this should work on all targets now.
122 (stop_whining): Default to zero, to shut up complaints
123 about bad symbol tables on many systems.
124 (free_named_symtabs): Just exit unless symbol_reloading.
126 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
127 and add comment explaining shared library screw.
129 * source.c: #if defined => #ifdef.
131 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
133 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
135 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
137 * doc/rdl-apps.texinfo: provide default readline-appendix finder
138 (doc/Makefile knows how to make one for local config)
140 * Makefile.in: use doc/Makefile for doc targets
142 * doc/Makefile: GDB documentation now has its own Makefile
143 doc/refcard.tex: renamed from "gdbrc.tex"
144 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
145 doc/gdbint.texinfo: add markup in "Cleanups" chapter
148 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
150 * values.c (basetype_addr): When reading target memory, use the
151 length of the basetype, not the upper type. We've only malloc'd
152 enough space for the basetype, leading to errors in free().
154 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
155 ends up as a function specially, since we know the actual type of
156 the pointed-to address. This (somewhat) fixes display of
157 expressions that include misc_function_vector names. Try `cond 1
158 !strcmp("a","b")' then `i b'.
160 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
161 The child can be proceeded from inside wait_for_inferior in
162 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
163 getting skipped in that case.
165 * expprint.c (print_subexp): Use filtered output, since the
166 subroutines we call use it, otherwise the output is horribly
167 mangled, since output of wrappable stuff comes out late.
169 * Makefile.in: Bump VERSION to 3.98.1
171 * infrun.c (child_create_process): Use execlp to find the
172 shell to exec our target program. This requires some fiddling
173 with `environ' since there is no execlpe().
175 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
177 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
178 Minor rearrangement of refcard permits two new make targets--
179 gdbrc.dvi DVI output for refcard, using CM fonts
180 gdbrc.ps PostScript refcard, using PS fonts
182 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
186 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
187 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
189 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
191 * doc/gdb.texinfo: last changes for release.
192 Minor typo and formatting fixes; incorporated most fixes remaining from
193 filed mail commenting on earlier drafts.
195 Added warnings: pipes don't work in run command;
196 conditions are converse of assertions;
197 step over fn without debug info goes to next fn;
198 vars may have "wrong" values near fn entrance, exit
200 Added example from Kingston on printing repeated nonadjacent values
202 Added explicit mention that in Emacs gdb mode C-c and C-z are like
203 shell mode for signals
205 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
206 doesn't sound so much like its parent "Stopping and Continuing"; also
207 moved entries on continue to top of section, so they don't get lost.
209 Improved installation directions in appendix, added manual formatting
212 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
214 * configure.in: Remove xm.h and tm.h even if we aren't linking
215 new ones, so "./configure sun4; ./configure none" does the right
216 thing. Assume that alldeps.mak and depend are already built in
217 srcdir, and avoid running "make" (particularly "make depend",
218 which involves "gcc") from inside configure. Build Makefile
219 directly rather than building Makefile.conf first.
220 * configure: Regenerate with above changes.
221 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
222 to 3.98. Revise gdb.tar.Z procedure to produce a file
223 called gdb-$(VERSION).tar.Z but which unpacks into a
224 directory called "gdb". Move non-source files out of
225 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
226 (depend): Don't try to do "gcc expread.y".
227 (expread.o): Update dependencies by hand.
229 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
232 Fixed a variety of small typos that prevented info from formatting
233 cleanly; altered too-long heading for GPL Appendix, as discussed
234 w/RMS; Changed date on cover to July 91.
236 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
239 (1) Applied some fixes due to comments from Larry Breed (easier ones
241 (2) Eliminated use of @footnote---had my doubts about it anyways, and
242 it's broken in latest texinfo
243 (3) Introduced *some* use of [] for optional arguments, where
244 explanation is not simpler by listing cmd w arg and cmd w/out arg
245 separately. Still not using @deffn.
246 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
247 couple of headings are too long. Need patches to texinfo or revision
250 * Partial update to README (which still needs work for this
251 release!): (1) use of configure corrected for new script,
252 (2) "make gdb.dvi" and "make gdb.info" mentioned.
254 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
256 * symtab.c (lookup_symbol): Don't complain right off about
257 no debug symbols; use the misc function vector first.
258 (list_symbols): Use misc function vector to find symbols
259 that don't have debug info, and print them.
260 (find_pc_symtab): Temporarily avoid fatal() when psymtab
261 PC range doesn't match symtab PC range, as it does on the
262 MIPS because our symtab reading isn't perfect.
264 * dbxread.c (dbx_symfile_read): Make warning about
265 "no debug symbols" slightly nicer.
267 * source.c (select_source_symtab): If "main" symbol exists,
268 but decode_line_spec can't find line info, don't just return
269 a zero; try other source symtabs or give an error.
271 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
272 their low addresses first, then rip through fixing high addrs.
274 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
276 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
278 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
280 * Minor, mostly mechanical, cleanup of doc subdir for clean
281 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
282 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
284 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
286 Mostly MIPS and general symbol-reading fixups.
288 * doc/gdbint.texinfo: Add documentation on symbol-reading
291 * mipsread.c: Remove kludges around #include "ecoff.h".
292 Remove redefinitions of a_magic, etc, no longer used.
293 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
294 Fix global overview comments to match symfile.c protocol.
295 (mipscoff_new_init): Eliminate cur_hdr if we have one.
296 (mipscoff_symfile_read): Eliminate unused code. Avoid
297 sorting all the symtabs, when all we have read here is psymtabs.
298 The symtabs are sorted as they are created anyway. Tell
299 condense_misc_bunches whether we're mainline.
300 (psymtab_to_symtab_1): Pass filename when recursing, to make
301 stack trace more informative.
302 (parse_partial_symbols): Assume cur_hdr as argument.
303 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
304 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
305 the TYPE_NAME of char *, since that's done in symfile.c.
306 (free_numargs, parse_symbol, add_symbol, add_block,
307 shrink_linetable): Declare these fns void.
308 (upgrade_type): Convert tree of if's to switch. Clean up
309 bogus "off == 0" handling with a complaint. Avoid setting
310 field bitpos and bitsize of array with lower and upper bounds.
311 Check specified bitsize of elements against their actual type's
312 bitsize, and complain if different. Complain about unknown
314 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
315 (psymtab_to_symtab_1): Print names of subsidiary files that
316 are being read in. FIXME, we read far too many files. This code
317 is not the problem, the problem is in parse_fdr where the psymtabs
319 (cross_ref): Result should indicate that we used one aux entry
320 normally, or two if we encountered a "next" entry. This used
321 to leave the caller pointing at the wrong aux entry.
322 (add_symbol): If overflowed cur_block, reallocate it larger,
323 chase all pointers to it, and complain(), rather than clobber memory.
324 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
325 (new_field): Only allocate one field initially, not two.
326 Pull ++ out of macro argument. Simplify.
327 (_initialize_mipsread): Avoid initialization of importd
328 global_psymbols and static_psymbols.
330 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
331 to properly set pst->symtab; avoid searching for it.
332 (symfile_fns): Improve comments, add a FIXME.
333 * dbxread.c: Update comments to reflect symfile protocol.
334 (read_ofile_symtab, end_symtab): Return the symtab.
335 (psymtab_to_symtab_1): Set pst->symtab.
337 * coffread.c (coff_symfile_read): tell condense_misc_bunches
338 whether we're mainline.
340 * symfile.h (sym_fns): Remove unused sym_discard member.
341 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
343 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
344 the environment variable is not.
345 * infcmd.c (finish_command): Use filtered printfs.
346 * cplus-dem.c: Add struct tags to a few unnamed structs.
347 * valops.c (value_coerce_array): Improve comments.
348 * valprint.c (type_print_varspec_suffix): Print array size only
349 if greater than zero.
350 * m88k-tdep.c: Shift some lines left by one space, that had
351 apparently been trashed at some point.
352 * TODO: More things to do, a few got done.
354 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
356 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
357 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
359 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
360 * expread.y, findvar.c, symmisc.c: Ditto.
361 * printcmd.c (address_info): Update printed forms of LOC_
362 symbols. Elim LOC_EXTERNAL.
363 (print_frame_args): Keep track of param stack offsets before
364 re-looking up to find the local register param is kept in.
366 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
367 Further integration of mipsread into gdb. Eliminate unused
368 routines, duplicate declarations. Handle static symbols in
369 psymtabs as well as external symbols. When reading symtabs,
370 insert symbols into the correct block (global, static, or a local
372 (read_mips_symtab, parse_partial_symbols): Don't pass useless
374 (mipscoff_symfile_read): Don't call select_source_symtab.
375 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
376 rather than SYMBOL_VALUE.
377 (parse_external): Comment clobbering of top_stack.
378 (parse_partial_symbols): Update comments. Allocate and parse
379 static symbols as well as external symbols. FIXME, enum values
380 are not handled in this pass, but should be. Inline new_psymbol.
381 Use SYMBOL_VALUE_ADDRESS.
382 (psymtab_to_symtab_1): Read symbols into global static block
383 by default (until enter some function's local block context).
384 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
385 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
387 * source.c (select_source_symtab): Select a source symtab
388 from either the symtabs or, failing that, the psymtabs.
389 (list_command): Update error message.
390 (forward_search_command, reverse_search_command): Use getc, not
391 fgetc, for speed. FIXME, add comment about buffers that die if
392 overrun by long line.
394 * values.c (unpack_field_as_long, modify_field): Avoid shifting
395 by an entire word, which is not portable, if we have a 32-bit
396 field. (Code in dbxread.c already turns such bitfields, if
397 aligned, into ordinary ints, but fixing this will help for other
398 symbol formats and for future changes.)
399 * core.c (core_open): Handle ANSI const brain death.
400 * utils.c (vprintf): Fix varargs typo.
402 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
404 * findvar.c (find_var_value): Handle &function better.
405 * TODO: Document work needed on &fn and &array.
406 * printcmd.c (print_address_symbolic): New arg is the prefix
407 to print if a name is printed.
408 (print_address_demangle): Honor "set print address" now.
409 Use new arg above to improve spacing of output.
410 * valprint.c (val_print): When printing function pointers,
411 print symbolic form too.
412 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
414 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
416 * core.c (memory_error): Reword error msg to mislead less.
418 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
420 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
421 parse_partial_symbols): Use newer BFD internals (external_filehdr
422 and external_aouthdr), byte-swap the fields that we care about
423 before using them, and make the file header data local to
424 read_the_mips_symtab rather than global.
426 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
428 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
429 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
431 * main.c (command_line_input): Flush stdout and stderr
432 before every call to readline. This reportedly fixes a bug
433 that comes up in Sys V running emacs-gdb and/or xxgdb,
434 when stdin/out are pipes or sockets.
436 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
438 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
439 Avoid declaring Makefile dependencies, because GNU Make stupidly
440 tries to update it if we do.
442 * coffread.c: Revise for minor changes to bfd internal coff
445 * configure: If -template= is given a relative path, make it
446 absolute before recurring in subdirectories.
448 * configure, configure.in, Makefile.in: Install "configure" script
449 as replacement for config.gdb.
450 * config.gdb, Makefile.dist, Makefile.sdir: Remove
451 * README: Update for configure, mostly. FIXME.
453 * Add dec3100 as equivalent to littlemips. Indicate in all host &
454 target config files that they are for the host. When the lines
455 get copied into the Makefile, this makes it more obvious what's
458 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
460 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
461 tabs, which end up in the disassembler output inadvertently.
463 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
465 Make it compile cleanly in an ANSI GCC2 environment.
467 * blockframe.c: <stdio.h>
468 * cplus-dem.c: free takes a void *, ifdef __STDC__
469 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
471 * defs.h (alloca): Avoid doing anything if alloca already def'd.
472 * stddef.h, stdlib.h: Remove these files.
473 * symtab.c: Avoid declaring qsort, close.
474 * symfile.c: Avoid declaring close.
475 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
476 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
478 Assorted other changes.
479 * dbxread.c: include "libaout.h", not "liba.out.h".
480 * printcmd.c (print_frame_args): Set recurse properly for
481 indentation of struct and array parameters.
482 * valops.c (value_cast): Allow cast to void.
483 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
484 single_step() in a target-independent fashion.
485 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
486 set up to be ready to continue. This makes us target independent.
487 * infptrace.c (child_resume): Remove call to single_step; now
488 can single step a SPARC target of any kind.
490 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
492 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
493 docn into separate sections---basically chapters, plus two loose
494 pieces that can be configured to go in different places. This
495 allows GNU m4 to preprocess the manual without coredumping.
497 * Makefile.dist: tell TeX where to find texinfo.
499 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
501 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
502 the new target "rdl-apps.texinfo" which captures the Makefile
503 variable that records where to find the Readline libraries.
505 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
507 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
508 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
509 * defs.h (const, volatile): Only define if not already defined.
510 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
512 * README: Update for release 3.95.
513 * config.gdb: Don't create readline dir in subdir builds.
514 * main.c: Include with "..." form for non-system include files,
515 so "gcc -MM" for "make depend" works.
516 Include readline files with "...h" rather than <readline/...h>.
517 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
519 * coffread.c: Undo minor damage done by Rich Pixley. Use
520 different internal and external representations of COFF
521 data structures. Use new BFD routines for swapping them in and
523 * symfile.c (free_named_symtabs): Avoid freeing file names that
524 are null or empty. Old i960 tools seem to produce files that
525 claim to have empty names, causing each successive file read
526 to blow away the previous one.
527 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
528 Move deferred_stores to top of file, but don't separate its
529 #define's from its variable. Add commentary.
530 * Makefile.dist: Fix Rich damage; undo "configure" changes in
531 favor of keeping the (working) config.gdb. Move readline

543 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
546 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
547 applied various small fixes due to or inspired by RMS comments
549 * doc/gdb.texinfo: finished using all RMS comments, save those for
550 appendices on readline and cmd history (which are in other source
553 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
555 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
556 chapter 9; (2) documented 'break' command's menu mode for
557 overloaded names, in response to hgs problem report C++ p-31
559 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
561 * doc/gdb.texinfo: (1) better introductory example; (2) more
562 consistent use of @code, @samp, @file, @kbd throughout; small
563 cleanups to first three nodes; (3) new "Contributors" node;
564 (4) Appendix, Renamed Commands; (5) divert specialized startup
565 instructions to "Targets" chapter for generic manuals, while
566 leaving them up front for manuals specific to specialized
567 environments; (6) apply fixes from RMS comments through chapter 4.
569 * pretex.m4: modify explanatory text slightly (and redefine
570 "regexp") to keep GNU m4 from complaining. (It still crashes
571 later, but one step at a time...)
573 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
575 * readline/readline.c (update_line): Avoid dereferencing a pointer
576 before comparing it to its bounds. Saber caught this.
577 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
578 and only set PC if tgetstr returned non-null. Saber caught this.
580 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
582 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
583 stuff for config manual) here where it counts; updated
584 to use new subdir structure (gdb/doc/).
586 * Makefile: generated from above via
590 * gdbint.texinfo: added instructions on generating gdb.info* files
591 locally for release. These are ordinary info
592 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
593 Makefile)---but due to use of texinfo 2, can't count on makeinfo
594 to generate these, so we distribute them already formatted.
596 * gdb.texinfo: included full Info node and menu crud (as generated
597 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
599 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
600 put in comments-for-future gdb.info target (one day makeinfo will
603 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
605 * gdb.texinfo: Updated to include new or old undocumented
606 commands, at least the following (perhaps some others I forgot to
607 record): info f, info float, info path, info program, info s, info
608 set, info source, info terminal, info types, info user, set/show
610 Also covered all recent GDB command renames for v4.
612 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
614 * mipsread.c: Rather than keeping count of how many symtabs
615 and psymtabs we have, for sorting purposes, count them when
616 we need to sort. This fixes bug in rereading of symbol tables.
618 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
620 * infcmd.c: renamed "info path" to "show paths"

635 symtab.h, target.c, target.h: Lint.
636 * core.c: setup and select frame after reading shared libs,
637 else reading shared libs will clobber them. Lint.
638 * utils.c (error): Force out any buffered wrap text.
640 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
642 * remote.c: Remove decls of memory_insert_breakpoint
643 and memory_remove_breakpoint, no longer used. (Suggestion of
646 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
647 to make it easier to interface to "configure"'d libraries.
649 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
651 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
652 aliases for set/show print.

1082 defined, define it to '$'.
1084 * arm-opcode.h: New file (same contents as before; it had
1085 just been left out of the distribution for a long time).

1156 New function to give correct error message.
1158 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

1161 target.c: Add target_preopen and target_command.
1163 (add_target): Call add_cmd and mess with targetlist->doc.
1164 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
1165 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.

1190 * symmisc.c (same): same.
1191 (free_symtab): Make non-static.
1192 * symtab.h (free_symtab): Declare as exported void fn now.
1193 * dbxread.c (end_symtab, end_psymtab): Change comments.
1194 (initialize_dbxread): Call dbx_new_init() in case the first
1195 command is add-symbols.
1196 * target.c (dummy_target): Permit add_syms_addr_command.
1198 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1200 Permit symbols to be superseded when new symbol files have
1201 been read in, particularly for VxWorks.
1203 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
1204 to the main file, as well as to include files. Also, put global
1205 functions into the global psymtab, to make "i fun" work.
1206 (end_psymtab): Free named symtabs and psymtabs for a file, once a
1207 new psymtab for it has been read.
1208 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
1209 a file, once a new symtab has been read for it.
1210 * mipsread.c: FIXME. We need to do the same for MIPS, but it
1211 looks harder to determine the top-level block before it's been
1212 queued to the psymtab list.
1214 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
1215 If we have wiped out any old symbol tables, clean up at end of
1217 (symbol_file_command): Don't reference symfile_fns if it's zero.
1219 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
1220 defines for the blocks of a blockvector that contain global and
1221 file-static symbols and the first of the smaller scope contours.
1222 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
1223 decode_line_1, make_symbol_completion_list): Use the above.
1224 * coffread.c (end_symtab, patch_opaque_types): Ditto.
1225 * dbxread.c (end_symtab): Ditto.
1226 * expread.y (block): Ditto.
1227 * mipsread.c (throughout): Ditto.
1228 * symmisc.c (free_named_symtabs): Ditto.
1230 * symtab.c (list_symbols): Process the first symbol of the
1231 static psymbols list.
1232 (types_info): Restore this function from its untimely #if 0.
1233 It's not perfect, but it is better than nothing.
1234 (_initialize_symtab): Restore "info types".
1236 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1238 * m68k-stub.c: Remote stub for 680x0's, created from
1239 rem-m68k.shar (which is removed).
1240 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
1241 Remove RCS log stuff now that we use CVS and it blows our diffs.
1243 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1245 * symmisc.c (free_named_symtab): Make it work, in its current
1246 kludgy fashion. Change result to indicate if we blew away bkpts.
1247 * dbxread.c (end_symtab): Accumulate result from
1248 free_named_symtab and print warning if we blew user's state.
1249 * symfile.h: free_named_symtab now returns an int.
1251 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1253 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
1254 is the first symbol read, even if not mainline.
1255 (dbx_psymtab_to_symtab): symfile might be zero, cope.
1256 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1257 (set_section_command): New command ("section xxx yyy" -- should
1258 be renamed to "set section xxx yyy" FIXME) which sets the
1259 base address of a section of the exec file, overriding the
1260 virtual address that BFD reports.
1262 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1264 * exec.c: Add add_syms_addr_command to exec_ops, so you can
1265 load symbols at any address while examining an exec file.
1267 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1269 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1270 for printing the float info is host-dependent, not
1271 target-dependent. FIXME.
1272 * i386-pinsn.c: Move #includes to top, remove useless ones.
1273 * i386-tdep.c: Don't bother including <.../reg.h> since we
1274 don't use it (and it doesn't exist on host systems).
1276 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1277 Convert negative numbers properly.
1278 (ieee_test): Make numbers really random; fix format arg.
1280 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1281 * core.c (core_detach): Unpush core_ops, which might not be on
1282 top. We used to just pop the top, which broke things. Don't
1283 need dont_repeat() any more.
1284 (core_file_command): Psst! Don't repeat it.
1285 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1286 * expprint.c (print_subexp): Avoid switch fallthru on
1287 BINOP_ASSIGN_MODIFY, so we can print += and such.
1288 * frame.h: Fix typo.
1289 * inflow.c (kill_command): After killing inferior, print our
1290 current frame in the core file, if we have one.
1291 (generic_mourn_inferior): When inferior dies, either select
1292 the current frame (in the new target, e.g. core file), or
1293 set both the current and selected frames to NULL.
1295 Changes from Peter Schauer.
1297 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1299 * Make all file names fit in 14 characters (sigh and damn!):
1300 mv hp300hpux-xdep.c hp300ux-xdep.c
1301 mv symmetry-xdep.c symm-xdep.c
1302 mv symmetry-tdep.c symm-tdep.c
1303 mv convex-opcode.h convx-opcode.h
1304 mv tm-vxworks960.h tm-vx960.h
1305 mv tm-vxworks68.h tm-vx68.h
1306 mv Makefile.srcdir Makefile.sdir
1307 mv gdb-int.texinfo gdbint.texinfo
1308 mv remote-sa.m68k.shar rem-m68k.shar
1309 mv remote-multi.shar rem-multi.shar
1310 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1311 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1312 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1315 * command.c (user_info_1, user_info): New command for listing
1316 the user-defined commands.
1318 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1320 * dbxread.c (really_free_pendings): Clear file_symbols
1321 and global_symbols after freeing them; otherwise, running
1322 this function twice (if it appears twice on the cleanup
1323 chain), we try to free things twice.
1325 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1326 based on text_addr (the address of text in core), not on addr (the
1327 offset between text in the .o file and in core). This change
1328 is from Peter Schauer.
1330 * main.c: Define ALL_CLEANUPS as a cast of zero.
1331 (return_to_top_level): Use it.
1332 (main): Do all cleanups after each command run as part
1333 of the gdb startup sequence. Also do all cleanups before
1334 entering the command loop, and every time we exit the command
1335 loop and reenter. Before, the cleanups from the startup sequence
1336 were being left undone until the first error!
1337 (command_loop): Rename do_nothing cleanup to command_loop_marker
1338 so we can see it easily when examining the cleanup chain.
1339 (init_signals): Add another do_nothing for signal handling.
1340 (quit_command): Only try to kill target if it has execution.
1341 Problems in the target stack got us into a state where
1342 inferior_pid was nonzero but none of the targets had execution.
1343 In this state you couldn't exit gdb.
1345 * dbxread.c: Two changes from Peter Schauer.
1346 (echo_command): Fflush output after an echo command.
1347 (show_history): Pass all args to cmd_show_list.
1349 * utils.c (init_malloc): Call mtrace to turn on tracing
1350 if the environment variable MALLOC_TRACE is set to a file name.
1351 * mtrace.c: Add source file which provides a log of every malloc,
1352 free, and realloc to a trace file.
1353 * mtrace.awk: Add source file which analyzes the trace file.
1354 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1355 (VERSION): Roll to 3.94.3.
1357 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1358 (check_duplicates): Don't bother with watchpoints.
1359 (set_raw_breakpoint): Comment about danger of this routine.
1360 (watch_command): Parse and eval all args before calling
1363 * solib.c (find_solib): Avoid error in referencing memory to
1364 see if any more shared libraries have been added. This is
1365 particularly useful if the target has terminated. Bug reported
1368 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1369 in bringing up 3.94.2 on the Sun-3.
1371 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1372 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1373 expression (in scope) before reenabling watchpoint.
1374 * signame.c (init_sigs): Add missing declaration of i, fix
1375 sys_siglist declaration.
1376 * source.c (list_command): Fixed range computation to use
1378 * stack.c (backtrace_command): Do not allow command if target has
1379 no stack, print informative error message.
1380 * target.c (target_command): Do not write into command line
1381 because this fails if the target command is used in a user defined
1382 command. [This change was enhanced by gnu to support any-
1383 unique-prefix matching on target names.]
1384 * valops.c (value_struct_elt): Avoid infinite loop on an
1385 erroneous attempt to print the member of function (try p main.p).
1387 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1389 * expread.y (name_no_typename): Avoid reduce/reduce errors
1390 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1391 Since the GDB parser really doesn't use name_no_typename in a
1392 name-only context, the parser can't tell the diff between
1393 names and numbers here. Avoid allowing a name_no_typename
1394 to be a NAME_OR_*INT to resolve the conflict.
1396 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1398 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1400 * valprint.c (val_print_fields): bitfield printing didn't handle
1401 byte order. Indirect through a few more fns to cope.
1403 * values.c (modify_field): also cope with byte order.
1405 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1407 Cleanup for release 3.94.2:
1409 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1410 include files. Roll version to 3.94.2.
1412 * coffread.c (init_stringtab): Read length into unsigned char
1413 array before swapping; don't assume 32-bit longs.
1415 * target.c (target_info): Don't bother with get_sym_file, just use
1416 the symfile global variable.
1417 * symtab.h, symfile.c (get_sym_file): Delete it.
1419 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1420 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1421 (read_type): Replace one more error() with complain().
1423 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1425 * i960-tdep.c: Fix copyright attribution.
1427 * config.gdb: Quote all backquotes in doublequotes. You can
1428 quote me on that. BSD 4.4 shell found this one.
1430 * infptrace.c (throughout): The third argument to ptrace is an
1433 * infrun.c (wait_for_inferior): When program has terminated, we
1434 have to call target_terminal_ours before we pop that target off
1435 the stack (e.g. before a call to target_kill or
1436 target_mourn_inferior). This fixes problem where a program
1437 terminates, then GDB stops for (tty output) and you have to type
1438 "fg" to the shell to resume it. FIXME: This code for what to
1439 do after termination really should be in normal_stop instead.
1441 * gdbcore.h (read_memory_check): Change declaration; it changed
1444 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1445 4.4 prereleases, this avoids a bug in their sgtty compatability
1447 * remote.c: Use terminal.h rather than hand-rolling the same.
1449 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1450 * utils.c (strsave, strstr): Fix arg types.
1451 * valprint.c (val_print): lint
1453 MIPS symbol table support from Per Bothner:
1455 * symfile.c (symtab_fns): Remove initializer table that needs to
1456 be hacked for each new symbol file format supported.
1457 (add_symtab_fns): New function, chains symbol table
1458 handlers into the global list.
1459 (symfile_init): Search this list.
1460 * symfile.h: Add next pointer, declare add_symtab_fns.
1461 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1462 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1464 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1465 symbol *). Thus, we no longer need the hack to trash
1466 pst->filename. Good, since that hack confused code in symfile.c!
1468 (reorder_symtabs, destroy_all_symtabs): Removed static
1469 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1470 Instead, the latter now uses a temporary array (stack-allocated
1471 from an obstack, and then freed).
1473 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1474 haven't been set in the outermost stBlock of a procedure. This was
1475 a problem with f77 binaries on Ultrix 4.?.
1477 (new_symtab, new_symbol, new_type): Continue changing code to use
1478 obstacks more and otherwise conform to dbxread internal style.
1479 Made the free_code of symtabs be free_linetable (as in dbxread)
1480 instead of free_contents. This implies memory leaks when reading
1481 a new symbol table, until the conversion is finished. Did change
1482 (struct symbol) and (struct type) to be allocated on the
1483 symbol_obstack. Blocks and blockvectors are among the things
1486 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1487 tested much, but it solved one problem (reported by Meissner), and
1488 cleans up some other things. The problem happened when an
1489 included file contains actual code (functions) and not just
1490 definitions. The mips coff is a little inconvenient there, since
1491 it may cause a procedure to be mapped to the wrong psymtab.
1493 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1494 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1495 this will need work for the new core paradigm.
1497 Opcode patches from the net:
1499 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1500 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1501 missing altogether - they are added here. From Bruce Bauman.
1502 * mips-opcode.h: The low mask for C0 instructions was too small.
1503 From Garrett Lau. I modified the fix to check the entire 32-bit
1506 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1509 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1511 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1513 * dbxread.c (read_type): Pointer subtraction (value_sub in
1514 valarith.c) sometimes failed because the types of the
1515 pointers being subtracted were not identical.
1516 These differed because dbxread.c was allocating pointer types
1517 using dbx_alloc_type+smash_to_pointer_type instead of
1518 lookup_pointer_type. I failed to find a justification for the
1519 former, so I changed it to use the latter. Similarly, I
1520 replaced smash_to_function_type by lookup_function_type,
1521 and smash_to_reference_type by lookup_reference_type.
1523 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1524 _initialize_mipsread): corresponding changes.
1526 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1528 * source.c (mod_path): Do tilde_expand on each component of the path,
1529 rather than on the (list of) paths as a whole.
1530 (print_source_lines): Set first_line_listed in addition to
1531 current_source_symtab and current_source_line. If the source was
1532 not findable, after a "dir" command to fix the problem,
1533 a "list" would get the wrong lines.
1535 While I was there... (gnu):
1537 * dbxread.c (read_type): Change error to complaint.
1539 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1541 First attempt at detailed understanding of symbol table memory alloc.
1543 * dbxread.c (dbx_symfile_read): Free our string table if we
1544 aren't the mainline. Free the "info" struct since we're done with
1546 (init_psymbol_list): Free any previously allocated psymbol lists.
1547 (): FIXME: Should realloc-down the psymbol lists when done reading
1548 the main symbol file?
1550 * symmisc.c (free_symtab): Free fullname field too.
1552 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1553 (REGISTER_ADDR): Make result type unsigned int.
1555 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1556 define REGEX must also define REGEX1 (its dependency).
1558 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1560 * tconfig/i960: No longer works, points you at vxworks960 or
1563 * xgdb.c, XGDB-README: Remove file. Users can get the much
1565 * Makefile.dist: Remove all trace of xgdb.
1567 * breakpoint.c (breakpoint_1): Pass demangle arg to
1568 print_address_symbolic.
1569 (clear_breakpoints): Remove unused function.
1570 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1571 (breakpoint_re_set): Use catch_errors to do them all anyway.
1573 * gdb-int.texinfo (Host versus Target): Add section on what is
1574 a "host" feature versus what is a "target" feature.
1576 * infcmd.c (path_command, path_info): Handle the PATH variable
1577 (object search path) as conveniently as the source search path.
1578 * environ.c (set_in_environ): Set some vars in GDB's environment,
1579 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1580 * source.c (mod_path): New function, from guts of
1581 directory_command, modifies a path. Used by path_command.
1582 (directory_command): Call it.
1583 * defs.h (strsave): Declare.
1585 * utils.c (sevenbit_strings): Add new printing option.
1586 (printchar): Use it.
1587 (strsave): Provide this handy helper routine.
1588 (set_width_command): Rename set_screen_width_command.
1589 (_initialize_utils): "set screen-width" => "set width";
1590 "set screen-height" => "set height"; add sevenbit-strings.
1592 * infcmd.c (do_registers_info): Print floating point registers
1593 in raw hex as well as float format, regardless of whether it is
1594 a "virtual" convertible register.
1595 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1596 regs as a double, just in case it's being used that way.
1597 * values.c (unpack_long): Comment on array/function coercion.
1598 (unpack_double): Argument is in target byte order now. For
1599 integer arguments, just call unpack_long and float the result.
1600 * m68k-tdep.c: include defs.h for "const" handling.
1601 * remote-nindy.c: Use ieee-float stuff.
1602 (nindy_fetch_registers): Unpack double regs to host double, then
1604 (nindy_store_registers): Pack extendeds to host double, flip
1605 around by misusing unpack_double, send as target double.
1607 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1608 zero, as when stopped at the first instruction of a process.
1610 * blockframe.c: Fix filename in comment (param.h => tm.h).
1611 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1612 * tm-68k.h: Fix typos.
1614 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1616 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1618 * coredep.c (fetch_core_registers): Pass end-address of register
1619 section to register_addr as expected. Don't call supply_register
1620 if we'd just pass it garbage.
1622 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1624 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1626 * target.c (push_target, target_info): Cast enums to int for < or
1629 * stack.c (print_frame_info): Identify source file & line
1630 even if we can't print it.
1632 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1634 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1636 Clean up IEEE floating point support.
1638 * ieee-float.h: New file.
1639 * ieee-float.c: Write real routines to convert between host
1640 doubles and various target IEEE extendeds.
1641 * m68k-xdep.c: Eliminate assembler code for extended floats.
1642 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1643 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1644 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1645 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1646 double_to_ieee_extended.
1647 * i960-tdep.c: Define ext_format_i960.
1648 * m68k-tdep.c: Define ext_format_68881.
1649 * sparc-tdep.c: Define ext_format_sparc, though unused.
1650 * Makefile.dist (HFILES): Add ieee-float.h.
1651 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1654 Obsolete the "coffstrip" program in favor of using BFD's strip.
1656 * nindy-share/coffstrip.c: Remove file.
1657 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1658 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1659 * tconfig/nindy960: Remove reference to coffstrip.o.
1661 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1663 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1665 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1666 * dbxread.c: Remove static symfile_bfd.
1667 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1669 * inftarg.c (child_detach): Pop the child_ops vector if the
1670 detach is successful.
1671 * remote-nindy.c (nindy_create_inferior): Don't push a new
1672 nindy_ops since nindy uses the same one for execution and memory
1674 * core.c (core_ops): Use child_attach and child_create_inferior
1675 rather than default attach and create_inferior functions.
1677 Handle floating point registers in core files.
1679 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1680 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1681 This version untested since BFD doesn't yet support sun3 core
1683 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1684 conventions. Fix comments and style. This version has not
1685 been compiled yet, since we have no HP inhouse.
1686 * core.c (get_core_registers): Look for two sections, ".reg"
1687 and ".reg2", and pass both to fetch_core_registers sequentially.
1689 Revise directory path yet again.
1691 * source.c (forget_cached_source_info): Not static any more.
1692 (init_source_path): New default source path is "$cdir:$cwd".
1693 (dir_command): Handle variable arguments ($cdir, $cwd).
1694 (source_info): Print "Compilation directory" rather than
1695 "Originally compiled in" to remind people of $cdir.
1696 (openp): If the path contains $cwd, use current directory.
1697 (open_source_file): If compilation directory is known, replace
1698 first $cdir in path with the compilation directory.
1699 (print_source_lines): Even if we can't print the lines, set the
1700 current symtab and line for future commands like "info source" or
1701 "breakpoint". Also, error message now contains the file name,
1702 line number, and file access error message.
1703 (_initialize_source): Fix help text to describe changes.
1704 * main.c (cd_command): Forget cached source info when we chdir.
1705 * utils.c (strstr): Add simple implementation.
1707 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1709 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1710 Byte-swap COFF symbol tables if necessary when reading them in.
1711 Use complain() to replace error message in one spot. Needs
1712 corresponding change in bfd/coff-code.h to make some symbol
1713 swapping routines non-static.
1715 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1717 Merge changes from Eirik Fuller, for UTek.

1720 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
1721 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1722 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1723 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,

1725 declarations of errno.
1727 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1729 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1730 <rpc/rpc.h> and <rpc/types.h>.
1732 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1734 * i960-tdep.c (examine_prologue): Add new argument limit,
1735 which stops the scan at the end of the prologue, or at the PC.
1736 This fixes a problem where it walks down into the code for the
1737 user's statements if that code looks like function prologues.
1738 Mark Fox and I have been bouncing this code back and forth, making
1739 small changes to it. Callers changed to match.
1741 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1743 Cleanup for gdb-3.94 release final:
1745 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1746 the .c files from vx-share and nindy-share, from the various
1747 macros, since they are not found via ALLDEPFILES.
1748 (SFILES): Add tm-i960.h.
1749 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1750 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1752 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1753 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

1757 * am29k-tdep.c: Add contribution line.
1758 (examine_prologue): Cache information about function prologues in
1759 the misc-function-vector to avoid lots of references over the
1760 serial line while examining instructions.
1762 * core.c (core_close): New function made from cleanup_core.
1764 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1765 remote-vx.c, remote.c, target.c, target.h,
1766 Update target_ops vector to add attach, close, and load entries.
1767 Use add_syms_addr_command, not add_file_addr_command, for
1768 add_file. Break out close routine from existing code.
1770 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1771 they are in an obstack.
1772 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1774 (define_symbol): Add symbol type parameter; change callers;
1775 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1776 it to influence the symbol class on the i960.
1777 (define_symbol): Swap LOC_CONST's into target byte order.
1779 * exec.c (exec_close): New function.
1780 (exec_file_command): Call it.
1782 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1783 Fix byte order of frame pointer.
1784 (read_var_value): Result of 0 if var's value can't be found,
1785 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1786 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1787 (locate_var_value): Use read_var_value and use its lazy address
1788 as the location of the var's value. Lint.
1790 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1793 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1794 obsolete Intel versions in favor of vxgdb versions.
1795 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1796 code dealing with byte order of values, which Intel did in host byte
1797 order rather than gdb-4's target byte order.
1798 (i960_frame_chain_valid): Move to nindy-tdep.c.
1799 (examine_prologue, skip_prologue, frame_find_saved_regs,
1800 frame_args_address, leafproc_return, saved_pc_after_call,
1801 pop_frame): Add vxgdb versions from Mark Fox.
1802 (examine_prologue, frame_struct_result_address): Add code
1803 to deal with the saved value of G13 (struct return address
1805 (frame_args_address): Modify Mark's version to prefer the
1806 saved value over the current value in the topmost frame.
1807 Cache result in the frame info to avoid performance hair in
1809 (print_fault): Add gdb960 code for printing faults.
1810 (_initialize_i960): Actually call check_host.
1812 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1813 add stub routines. FIXME, these currently just return zero!
1815 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1816 (attach_command): Call target_attach, not target_open, now.
1818 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1819 (child_attach): Rename from child_open.
1820 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1821 don't confuse it with a zero step_resume_break_address.
1823 * inftarg.c (child_detach): Eliminate inferior_pid test.
1824 (child_files_info): Clean up message a bit.
1825 (child_ops): Use child_attach, not child_open, to attach.
1827 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1828 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1829 findvar.c to here, since it depends on the contents of the
1830 shadow_contents of breakpoints, but keep if #if 0 since it is
1833 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1836 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1837 (ptype_command, display_command): Eliminate have_inferior_p and
1838 have_core_file_p in favor of target_has_stack or
1839 target_has_execution.
1840 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1841 code for actually finding the values of arguments, though we still
1842 keep track of the maximum stack offset for use in printing unnamed
1843 arguments. Handle missing FRAME_ARGS_ADDRESS.
1845 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1846 (struct nindy_regs): Define registers passed to/from nindy.
1847 (nindy_fetch_registers, nindy_store-registers): Translate between
1848 nindy and GDB formats for the registers.
1849 (dcache_init): Statically allocate the cache, since it was being
1850 allocated by a malloc that was never freed anyway.
1851 (nindy_create_inferior): Error, not core dump, if no exec file.
1852 (nindy_before_main_loop): Use target_load, not target_add_file.
1854 * remote-vx.c (net_load): Specify large timeout for load
1855 requests. Allow user to break out with INTERRUPT.
1856 (net_break): Remove useless code, clean up. Change callers.
1857 (parse-args, skip_white_space, find_white_space): Clean up arg
1858 parsing to cope with quoted strings.
1859 (net_wait, net_quit): Never call error, just return status.
1860 (vx_read_register, vx_write_register): Cleanup status checking.
1861 #ifdef the code based on which CPU we are using (960 or 68k),
1862 FIXME, this should be completely general but it isn't yet.
1863 (vx_xfer_memory, vx_resume): Cleanup status checking.
1864 (vx_run_files_info): Improve message.
1865 (vx_load_command): Renamed from vx_add_file_command. Allow load
1867 (net_ptrace): Remove unused routine.
1868 (vx_wait): Adopt code from vxgdb960 to cope with broken
1869 connections to target machine and prompt to disconnect. Remove
1870 debug printouts. Map some EVENT_'s to SIGnals.
1871 (add_symbol_stub, vx_open): Print names of object files we found,
1872 and "ok" if we read their symbols OK. Clarify output in general.
1873 (vx_attach, vx_detach, vx_kill): Add these commands.
1874 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1875 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1876 "info files" output, and create_inferior, since we already have
1879 * stack.c (frame_info): Replace Frame_unknown with 0.
1880 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1881 (return_command): Pop until the PC matches as well as the FP,
1882 so it works even if the FP is shared with another function,
1883 as in "frameless" or "leaf" procedures.
1885 * symfile.c (load_command): renamed from add_file_target_command.
1886 (add_syms_addr_command): renamed from add_file_addr_command.
1887 (add_syms_command): Stub to call target_add_syms.
1888 (_initialize_symfile): Change command names and descriptions,
1889 add-file => add-syms, and load from alias to its own command.
1891 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1892 maybe_kill_then_create_inferior): Default for attempts to start
1893 a process, if one is already running, is to ask about killing
1894 it and retry if yes.
1895 (upstack_create_inferior): #if-0 it, strata obsolete it.
1896 (push_target, unpush_target, pop_target): to_close() a target
1897 before unstacking it.
1898 (target_info): Renamed from target_files_info.
1899 (_initialize_targets): Rename "i files" as "i target", accessible
1902 * target.h: Improve comments about the target_ vectored routines.
1904 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
1905 Convert commenting style to standard GNU style.
1906 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
1907 (SKIP_PROLOGUE): No longer a no-op.
1908 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1909 (*_REGNUM): Sort register numbers.
1910 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1911 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1912 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1913 are now 10 byte extendeds, not 8 byte doubles.
1914 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1915 for nindy versus vxworks targets. FIXME, this should possibly go
1916 in the target vector.
1917 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1918 frame_saved_regs and arg pointer with each frame.
1919 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1920 (FRAME_ARGS_ADDRESS): Use cached result.
1921 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1922 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1923 (PRINT_RAMDON_SIGNAL): Call print_fault.
1924 (POP_FRAME): Now works.
1926 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1927 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1928 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1929 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1932 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1933 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1935 * valarith.c (value_subscripted_rvalue): Avoid handling
1936 floats and doubles specially; it gave alignment errors. Lint.
1938 * valops.c (value_of_variable, value_of_this): Error if unknown
1941 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1942 to avoid alignment problems.
1943 (value_print): Handle unknown value address.
1944 (cplus_val_print): Two args are ignored; remove them. Change caller.
1945 (val_print): Use unpack_long rather than pointer-deref.
1948 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1949 to avoid alignment problems.
1950 (value_being_returned): Error if return value unknown.
1951 (set_return_value): Add bogosity warning, FIXME. *
1953 * TODO: A woman's work is never done.
1955 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1956 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1957 Add ieee-float.o to OBS.
1958 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1959 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1960 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1962 Changes to generalize the VxWorks RPC protocol slightly, to handle
1963 i960 as well as 68000.
1965 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1966 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1967 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1968 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1969 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1970 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1971 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1972 so they will move in target byte order rather than network
1973 byte order (happens to be the same).
1975 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1977 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1979 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1982 Add contribution lines to various files, showing where they
1985 * breakpoint.c (break_insn, check_break_insn_size,
1986 read_memory_nobpt): Remove to mem-break.c.
1988 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1991 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1992 entry has bad register number. This change is not
1993 tested in this release, FIXME.
1995 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1998 * value.h: Force value's contents field to be aligned to hold
1999 at least a double or a long long (if supported). This avoids
2000 doing bcopy's in and out of the contents field.
2002 (step_1): Avoid coredump under obscure circumstances when we
2005 * symtab.h (misc_info): Add field to misc function vector for
2006 any kind of cached information the target code desires. AMD
2007 29000 uses this to avoid repeating examine_function_prologue's.
2009 * coffread.c: Lint. Remove static symfile, read_section_header.
2010 core.c (have_core_file_p): Lint: remove.
2011 expprint.c (print_subexp): Lint.
2012 infptrace.c, valops.c, valprint.c: lint.
2014 Roll in changes from vxgdb-5.0.1:
2016 * symtab.h: Comment byte order of each address class. Add
2017 LOC_LOCAL_ARG for frame-relative args (960).
2018 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
2019 symtab.c, symmisc.c: ditto.
2021 * infrun.c (init_wait_for_inferior): Clear stop_signal.
2023 * remote.c (remote_resume): Error if resume with a signal.
2025 * symfile.c (prim_record_misc_function): Clear misc_info.
2026 (fill_in_vptr_fieldno): Check stub type of arg.
2028 * valops.c (value_cast): Avoid looking up names of types whose
2029 name we don't know, to prevent coredump. Sun CC produces typedef
2030 rtx and the name of *rtx is zero...
2032 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2034 Roll in changes from final AMD 29000 port (Tiemann).
2036 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
2037 for ../include/a.out.encap.h. This might not work now that BFD
2038 is separately compiled. Instead, BFD support for encap will have
2039 to translate machine type 29k into the right COFF_MAGIC.
2041 * infcmd.c: Remove references to inferior_pid that aren't used
2042 in actual ptrace calls; use target_has_execution, etc.
2043 (have_inferior_p): Remove function.
2044 (program_info): Print target info rather than "process number";
2045 avoid gratuitous messages unless from_tty.
2046 (run_stack_dummy, finish_command): Set proceed_to_finish.
2047 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
2048 main.c: Lint. Lose have_inferior_p().
2049 inferior.h (have_inferior_p): Remove, lint.
2050 (proceed_to_finish): Add flag to ask that all regs be saved
2051 by normal_stop, for the few commands that need it, speeding up
2052 serial I/O. Add comments to stop_registers.
2054 * remote-eb.c: Remove newline from breakpoint message we grep
2055 for. Never time out when running the user program.
2059 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2061 Roll in changes from vxgdb-5.0.1:
2063 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
2064 symbol in its raw form, we are processing an unlinked ".o" file.
2065 See if the target environment has assigned it an address, using
2066 target_lookup_symbol (VxWorks does), and enter it into the symtab
2069 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
2070 68k versions for a simpler version that assumes zero FP at bottom.
2071 Fixes bug of truncated stack reports.
2073 * target.h (target_lookup_symbol): Define this routine's args
2074 and result, finally.
2076 * target.c (nosymbol): Default routine for target_lookup_symbol.
2077 (target_default): Default lookup_symbol and call_function too.
2078 (files_info): Only print has_all_memory warning if a non-dummy
2081 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
2082 vx_convert_from_virtual): If target does not have floating point,
2083 zero register "values", and avoid doing cross-net conversions.
2084 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
2085 (vx_open): Rearrange code that attaches to target and reads
2086 symbols for all loaded modules, to work if some of the modules
2087 are not accessible. Add symbol_stub() and add_symbol_stub()
2088 as callbacks from catch_errors(). Allow connect attempt to be
2089 interrupted painlessly with ^C (FIXME, there are still some bugs
2090 if the interrupt happens during symbol reading.). Print
2091 final message with puts_filtered, since symbol messages are
2096 * main.c (catch_errors): Only print errstring if non-null.
2097 (command_loop): Avoid an ioctl per command to test ISATTY.
2099 * remote-vx.c (net_load): make static; avoid sophomoric msg.
2100 (vx_xfer_memory): Return correct result!
2101 (vx_files_info): Indicate whether target has float or not.
2102 (vx_lookup_symbol): Complain, not error, if target gone.
2103 (vx_open): Print "Connected" msg before disabling immediate-quit.
2104 [FIXME: lookup_symbol and vx_open changes need testing.]
2106 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
2107 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
2108 contributor lines and update copyrights to 1991.
2110 Changes from an attempted H-PUX host port:
2112 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
2113 defines PT_ATTACH and PT_DETACH but not PT_KILL.
2114 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
2115 * remote-vx.c: include <sys/time.h> for HPUX.
2116 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
2117 "core_file_command" routine to BFD regime. May not work yet.
2119 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
2121 * xgdb.c: Replace X10 version with some VJ version.
2122 (FIXME: Its copyright assignment is not on record.)
2123 * xgdb.c: Update include files to X11R4 (Xaw crud).
2124 (xgdb_display_source, create_text_widget): fix call to
2125 get_filename_and_charpos. Rewack source window stuff for X11R4
2126 (gleaned from include files, and "nm's" of binary libraries, since
2127 I had no doc available).
2128 (append_selection, append_selection_word): Disable with FIXME
2129 since R4 changed interface here.
2130 (create_buttons): Add back the old set of buttons.
2131 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
2133 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
2134 Roll VERSION to 3.94 (not yet final though).
2136 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2138 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
2139 obstack_int_grow, obstack_int_grow_fast): Eliminate
2140 cast on left of assignment, which gives MIPS cc fits and is
2143 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
2144 F_ALIAS. Use printf, not fprintf, when not passing a file
2146 (compare_opcodes): Check that identical instructions have
2147 identical opcodes, complain otherwise.
2149 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
2150 was reported by Roland McGrath.
2151 (unimp): Only match if exactly zero instruction. (Roland)
2152 (branches and traps): Generate all variations of these
2153 instructions with macros, based on a single call that defines
2154 each condition name and its binary representation.
2155 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
2157 * valprint.c (val_print_fields): Take, and use, format parameter.
2158 This means that "p/x struct" again prints the elements in the
2159 desired format. Changed callers.
2161 * stack.c (frame_info): Use filtered output, and indicate wrap
2162 points. Remove kludgy formatting designed to avoid line wrap.
2164 * utils.c (wrap_here): If the line is already full (because
2165 we had printed a long indent or long wrapped string), do an
2166 immediate newline-and-indent.
2168 * m68k-pinsn.c (print_insn_arg): Bugfix from
2169 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
2170 instruction is incorrectly disassembled as bkpt #8.
2172 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
2173 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
2174 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
2175 and then will dump core (sometimes). I traced it back to an
2176 uninitialized symfile_name in psymtab_to_symtab.
2177 (const_vol_complaint): Add quotes to message.
2178 (define_symbol): Only believe line number if gcc_compiled.
2179 Avoid allocating symbol if we will not return it.
2181 Add target strata support so that newly established targets go
2182 into their right place in the target stack (e.g. a new exec file
2183 doesn't wipe out the ability to access the running process).
2185 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2186 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2187 and initialize it properly in all the targets.
2189 * target.h: Document strata. Change return type of push_target.
2191 * target.c (nomemory): new function for dummy memory access.
2192 (tcomplain): Rename complain, now also used in symfile.c.
2193 (push_target): Push targets within strata. New return value shows
2194 whether new target is on top of stack or not. Always keep dummy
2196 (target_files_info): Ignore dummy target.
2198 * core.c (core_open): Warn user, and skip accessing file, if the
2199 core target is not the topmost target in the stack.
2200 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2203 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2204 target_ops, it doesn't belong there since we have no regs there.
2205 Change name of target from machine => memory to clarify.
2207 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2209 * Freeze version 3.93 for release.
2211 * Makefile.dist: Handle vx-share and nindy-share subdirs
2212 properly when building gdb.tar.Z.
2214 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2215 printed in various places, so I could change just one copy.
2217 * dbxread.c, coffread.c: Change references to bfd->iostream
2218 to cast to FILE *, now that BFD avoids needing types defined
2219 in other header files.
2221 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2223 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2224 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2225 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2226 (actually gcc -Wall).
2228 * dbxread.c: Remove first_global_sym, last_global_sym, since
2229 they are never referenced.
2231 * defs.h (baud_rate): Declare.
2232 main.c: Define it, and add the -b option to set it.
2234 * gdb-int.texinfo: Add text on how to define a new host or target
2235 architecture, prompted by Per Bothner's questions about MIPS
2238 * gdb.texinfo: Document "complaints". Change doc of -q since
2239 gdb no longer prints the copyright and blurb if you specify a file
2240 name to be debugged (just like Emacs). Add doc for Nindy-specific
2241 command line flags for specifying target serial port and such.
2242 Update copyright to 1991.
2244 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2245 has taken over for us the job of ripping up executable files. The
2246 crud caused Per Bothner's port to not compile.
2248 * infrun.c (normal_stop): Avoid printing "Program exited
2249 normally" if we are in batch mode. This allows a GDB which
2250 executes a program on a target system, to behave like a Unix
2251 command (input from stdin, output to stdout, no extraneous
2254 * main.c (main): Allow additional machine-dependent command line
2255 options to be specified with the ADDITIONAL_OPTIONS,
2256 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2257 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2258 processing to occur just before the main loop with
2259 BEFORE_MAIN_LOOP_HOOK.
2260 (main): If a "core file" argument is specified, and it is not a
2261 core file, try it as a process ID to attach.
2262 (symbol_completion_function): Attempt to cope with
2263 "show screen-" TAB, not very successfully. This needs more work,
2265 (batch_file): New function, returns whether we are reading
2266 commands from an interactive tty on stdin, or from somewhere else.
2267 Called by normal_stop since it doesn't get from_tty passed down
2268 to it like many commands do.
2270 * remote-nindy.c: Handle command line options for nindy
2272 (nindy_before_main_loop): Prompt user for tty name if they
2273 don't specify it before getting to the interactive command loop.
2275 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2276 and -r command line options. Also add hook before main loop
2277 to make it easy to specify a tty.
2279 * TODO: More things to do, one done.
2281 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2283 * dbxread.c: Make complaint() calls pass pointer, not struct.
2284 Add complaints about badly formatted C++ type information
2285 (const/volatile indicator, and parse errors resulting in
2286 error_type). Fix C++ virtual member fn comment.
2287 (read_struct_type): Avoid bumping pointer if we got a parse
2288 error; this prevents our walking beyond the end of a string.
2289 Terminate loop on null char as well as semicolon.
2290 (process_one_symbol): Fix the LBRAC fix so that it uses the
2291 last previous SLINE, FUN, or SO record's PC address. C++ debug
2292 symbols did not have SLINE records in a useful order compared
2293 to the LBRAC records.
2294 (define_symbol): Handle "catch" records.
2296 * symtab.c (check_stub_type): Added new complain
2297 `stub_noname_complain' and added a consistency check to
2298 keep the debugger from crashing when finishing from an
2299 exception frame. A real fix will be needed later.
2301 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2303 * infcmd.c (attach_command): Make global.
2305 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2306 but make them easy to comment out. Perhaps later they should
2307 be enabled by what CPU you configure for? FIXME.
2308 (VERSION): Roll to 3.93.
2309 (pinsn.o): Remove rule for obsolete file.
2310 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2312 Run down a problem that manifested by printing the wrong function
2313 name in stack traces of read_ofile_symtab. Turned out that the
2314 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2315 the LBRAC symbol with an address in the *data* segment, which
2316 blew our binary search through the blocks.
2318 * dbxread.c: Use the complain() facility consistently to bitch
2319 about problems in the symbol file we are reading.
2320 (finish_block): Add code to check the nesting of the blocks;
2321 complain and Procrust them to fit if wrong.
2322 (make_blockvector): Check the order of the blocks, complain
2323 [but don't cope] if wrong.
2324 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2325 symbols to be sure their PC value is greater than the last SLINE
2326 (line number) symbol we've seen, complaining and adopting the
2327 SLINE PC value if wrong.
2329 * symfile.h (struct complaint, complaint_root, complain,
2330 clear_complaints): Add.
2331 * symfile.c (complain, complaint_root, clear_complaints): Add
2332 facility to deal with non-fatal complaints and to regularize their
2334 (symbol_file_add): Clear complaint counters to allow new complaints.
2335 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2337 * dbxread.c (dbx_symfile_read): Remember the address and size
2338 of the string table for the main symbol file, so we won't read it
2340 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2341 to avoid reading the string table yet again. Lint.
2342 (throughout): Improve filtered output, including word wrap.
2343 (read_range_type): Improve Bothner's fix to handle other types too.
2345 * utils.c: Improve line wrap implementation. Handle unlimited
2346 width by making chars_per_line unsigned.
2347 (puts_filtered): New, easy, function.
2349 * defs.h (puts_filtered): add.
2351 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2352 call the identical sort_symtab_syms() in symfile.c instead.
2354 * expread.y: Suggest the `file' command rather than `symbol-file'.
2356 * command.h (enum var_types): Add zinteger for seroable
2358 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2359 nested if's into a switch.
2361 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2362 we did not stop because of a breakpoint (it must have been for
2363 some other reason, like a "stepi"), so don't print anything.
2365 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2366 doesn't include <sys/types.h>, old SunOS's require it for
2369 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2371 A test port of gdb-3.92.6 to the Sony NEWS.
2374 Don't normally link in remote- or vx stuff.
2375 Some of it doesn't compile, and it wastes space for 99% of the users.
2376 Remove reference to no-longer-used HAVE_VPRINTF.
2377 Fixed BFD_DEP typo to BFD_DIR.
2379 Fix cast in arg to bfd_h_getlong.
2380 Make char *prefix be const.
2381 Fix how certain range types are mapped into builtin unsigned int types.
2383 Remove 2 #includes. They cause errors (on Sony, at least),
2384 and aren't needed (they wern't in earlier versions).
2386 print_address_symbolic should never demangle labels
2387 (since it prints *assembler-level* labels).
2389 [This was superseded by the change to printcmd below.]
2392 Add some "volatile" return types to avoid warnings.
2393 If MISSING_VPRINTF add vprintf function and not just macro
2394 (since vprintf is used in printcmd.c).
2396 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2397 (The latter isn't grokked by some PCC-based compilers.)
2399 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2401 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2402 * nindy-share/coffstrip.c
2403 Added some forward declarations (otherwise, gcc complains
2404 about implicit extern redefined as static).
2406 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2408 Changes inspired by Per Bothner:
2409 * printcmd.c (print_address_symbolic): Take additional parameter
2410 specifying whether to demangle.
2411 (print_address): Pass in asm_demangle to control demangling.
2412 (print_address_demangle): New fn, takes explicit arg to control
2414 * utils.c: Add new vars demangle and asm_demangle, and let them
2416 (fputs_demangled): If !demangle, just print the argument.
2417 (fprint_symbol): If !demangle, just print raw symbol.
2418 * valprint.c (val_print): Call print_address_demangle rather than
2419 print_address, to cause demangling to depend on the global
2420 rather than assembler-level demangling setting.
2421 * WHATS.NEW, gdb.texinfo: Document.
2423 * main.c (show_command): Show all settings if no arg.
2424 (initialize_main): Make "info set" the same as naked "show".
2425 * command.c (cmd_show_list): Handle prefix commands in the
2426 list, and print the name of the setting as well as its English
2427 description and value.
2429 Allow gdb functions to specify where a line should wrap if it
2430 exceeds the size of a terminal line. Use it to make the output
2432 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2433 of the right size when screen width changes.
2434 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2435 (wrap_here): New fn, indicates a point in the output where we
2436 should wrap the line rather than just letting it overflow at a
2438 (fputs_filtered): Implement wrapping.
2439 (n_spaces): New fn, returns a pointer to N spaces.
2440 (print_spaces_filtered): Use n_spaces.
2441 * defs.h (n_spaces): Declare.
2442 * stack.c (print_frame_info): Wrap with 4-space indent after
2443 fn name and before filename and line number.
2444 * printcmd.c (print_frame_args): Wrap with 4-space indent
2445 before each argument name is printed.
2446 * valprint.c (value_print): Wrap with no indentation before
2448 (val_print_fields): Wrap with indentation relative to nesting
2449 level before each field name.
2450 (val_print): Wrap with nesting indentation before array elements.
2451 * command.c (do_setshow_command): Avoid extra newlines,
2452 wrap with 4-space indent around values printed, end with period.
2453 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2455 * breakpoint.c (breakpoint_1): Implement addressprint for
2456 "info breakpoints" display. Change file name and line number
2457 format to " at file:nnn" rather than " (file line nnn)".
2458 * gdb.texinfo: Document.
2461 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2463 Frozen for gdb-3.92.6 release.
2465 README, WHATS.NEW: Update for 3.92.6 release.
2467 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2468 coffread.o from configs since it is now built by default.
2469 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2470 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2471 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2472 from configs since it is now built by default.
2474 Makefile.dist: Update for release 3.92.6. Handle files that
2475 have been moved to ../include, ../getopt, or ../bfd. Add
2476 saber.suppress and tests directory. Add config.status to
2477 the release (it will say "none").
2479 coredep.c: Minor formatting fixes.
2481 These changes were made in early December but only checked in now:
2482 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2483 nindy-share/nindy.c: lint
2484 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2485 register values coming back from the target; we store values
2486 in target byte order everywhere.
2488 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2490 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2492 * valprint.c (cplus_val_print, val_print_fields): New functions,
2493 which print C++ objects. They conspire to avoid printing a
2494 virtual base class more than once, following all the twists and
2495 turns of C++ virtual base rules.
2496 (val_print): Call the above rather than do it by hand.
2498 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2499 symbol file, not for added files like shared libs. This really
2500 needs to be generalized to a timestamp per file.
2502 * core.c (cleanup_core): Avoid coredump if no core file.
2504 * config.gdb: Accept -host or -target in place of +host or
2507 * coffread.c (find_linenos): Avoid desupported BFD interface
2508 to line numbers. We still read them manually rather than using
2509 BFD's "generic" features.
2511 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2513 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2515 * Makefile.dist: Eliminate use of $< in explicit targets.
2517 * readline/Makefile: Use $< rather than $*.c, which does not
2518 include the VPATH in GNU Make.
2520 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2521 copies of tconfig/i960, added for global configuration
2522 compatability. All i960 versions can read both coff and b.out.
2524 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2525 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2528 * TODO: Think of more things to do.
2530 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2532 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2533 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2534 64-bit float conversion.
2536 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2537 equivalent to sun?os4 so global config works.
2539 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2541 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2543 * main.c: Only declare linesize once; declare pagesize not at
2544 all, since it is never used.
2545 (main): Clear newly allocated line before it is used.
2547 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2549 Further stabilization for the Intel 960.
2551 * Makefile.dist: Parameterize the location of the "include"
2552 and "bfd" directories, as well as "getopt". Add symfile.c.
2553 Link in both dbxread and coffread. Fix up "make depend" to
2554 rewack the locations of include, bfd, and getopt in its output.
2556 * README: Document moving include files, improve some of
2559 * coffread.c: Move common code out to symfile.c. Change
2560 symbol_file_command style interface to use new *_symfile_init
2561 and *_symfile_read interface under BFD. Use BFD internal
2562 info to locate line table, symbols, etc.
2564 * core.c (core_fetch_registers): Rename to get_core_registers
2565 to avoid confusion with fetch_core_registers.
2566 (register_addr): Move to coredep.c, which is already machine
2567 dependent. This leaves core.c pretty clean of dependencies.
2569 * coredep.c (register_addr): Accept this routine from core.c.
2571 * dbxread.c: Move common code (with coffread.c, etc) into new
2572 symfile.c. Each psymtab now contains a pointer to the
2573 format-dependent function that knows how to read it in. Make
2575 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2576 (process_one_symbol): Add code to complain about a "compiler bug
2577 we muzzle here", if we actually see it.
2579 * eval.c (evaluate_subexp): Insert missing "break" statements
2580 in code that determines whether a variable is an lvalue in
2581 memory, register, or whatever. I detected this via a compiler
2582 bug in which it *almost* mashed out the whole switch statement.
2584 * gdb-int.texinfo: Add minor sections on configuring gdb for
2585 release, and about the README file.
2587 * infcmd.c (registers_info): Fix formatting somewhat. Still
2588 not as pretty as before, but it handles byte swapping.
2590 * remote-nindy.c: If data cache routines are interrupted while
2591 waiting for the remote end, be sure that any uninitialized cache
2592 blocks are on the free list, not on the valid list!
2594 * symfile.h: Flesh out this header file with all the various
2595 routines and variables that have been merged in from dbxread.c
2596 coffread.c, and symtab.c to symfile.c.
2598 * symfile.c: New file, containing code common to dbxread.c,
2599 coffread.c, and some code from symtab.c. All generic code for
2600 reading symbol files should be in here now.
2601 (unrecord_misc_function): Remove unused function.
2603 * symtab.h: Remove file-reading things to symfile.h.
2605 * symtab.c: Remove file-reading things to symfile.c.
2607 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2608 to decode i960 fault types.
2610 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2611 target.c: Change type of the "resume" function from int to void,
2612 since its result was never used.
2614 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2616 * main.c: Replace "stupid" with "caution"; you now "set caution
2619 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2621 * infcmd.c (do_registers_info): Call val_print to deal with the
2622 byte order of the registers being printed. FIXME, this makes
2623 the formatting of the output uglier.
2625 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2626 defined, call it for signals the debugger doesn't itself use.
2627 The i960 uses this for more detailed fault information.
2629 * remote.c (remote_open): If arg is null, print help rather than
2632 * sparc-xdep.c (register_valid): Avoid declaring size, since
2633 various modules will think of various sizes depending on the
2634 architecture of their tm-file. FIXME, we need protection against
2635 actually entering one of those modules, which would clobber
2636 storage if not for the target architecture compiled into gdb.
2638 * stack.c (up_command, down_command): Always print the frame
2640 (up_silently_command, down_silently_command): New commands
2643 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2645 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2646 more parameters than it used to.
2648 * findvar.c (registers): Increase slop to 256 bytes, which should
2649 protect us against even most RISC machines with large register
2651 (locate_var_value): Move declaration inside related ifdef.
2653 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2654 throughout, to avoid throwing away buffered input from the board.
2655 (nindy_wait): Supply_register takes addr_of_value, not value.
2656 (i960_print_fault): Renamed from i80960_fault.
2657 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2658 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2660 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2661 we can set the PC in the call to proceed(). Unpush nindy_ops
2662 before pushing it on top, to avoid message to user. Eliminate
2663 commentary from Unix machines that just misleads here.
2664 (reset_command): Fix error message to suggest target command.
2666 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2668 Release 3.92.5 as frozen.
2670 Stabilize the merged release...with help from lint, Saber C,
2673 Everywhere: Add include files needed to declare return types
2674 of functions called.
2676 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2678 * breakpoint.h: Add undeclared breakpoint functions, and some
2679 functions for display handling since I couldn't think of a better
2682 * breakpoint.c (insert_breakpoints): Make code for disabling
2683 shared library bkpts more likely to work. It's used when we
2684 rerun a program and stop before the shared library has been
2686 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2687 cast from pointer, so it squeezes through catch_errors.
2688 (bpstat_stop_status): Fix logic broken some time ago. We now
2689 always create a bpstat if the stop address matches a breakpoint,
2690 even if we don't stop there -- just like the old code used to do
2691 before I got my fingers into it (sigh).
2692 (breakpoint_1): Print "ignore count" after "stop only if"
2693 condition, since that's how it actually works.
2694 (mention): Handle watchpoints as well as breakpoints.
2695 (watch_command): use set_raw_breakpoint and mention to do most
2696 of the work (and initialize all the fields!). Only pass one
2697 arg to parse_c_expression, since that's all it takes.
2699 * command.c (not_just_help_class_command): Rename arg to args
2700 since we ignore "unused argument" warnings on vars named "args".
2701 inflow.c (child_terminal_info): ditto.
2702 infptrace.c (kill_inferior): ditto
2703 main.c (catch_errors, version_info, quit_command, pwd_command,
2704 source_command, dump_me_command, editing_info,
2705 set_history_size_command, set_history, show_history,
2707 stack.c (locals_info): ditto
2708 target.c (target_files_info): ditto
2709 valprint.c (set_input_radix, set_output_radix): ditto
2711 * core.c: Remove old variables for handling core and exec file
2712 sections (data_start, data_end, stack_start, stack_end,
2713 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2714 text_end, exec_data_start, exec_data_end, text_offset,
2715 exec_data_offset, data_offset, stack_offset). They're
2716 superseded the more general build_section_table and
2718 (get_exec_file): Mention the `file' command.
2719 (read_memory_check): Rename to memory_error, and only call it
2720 in the case of an actual error.
2721 (read_memory, write_memory): call memory_error.
2722 (core_fetch_registers): Register section name is ".reg".
2724 coredep.c: Remove a bunch of crud now that all this file does
2725 is pull the registers out of a core file.
2726 (fetch_core_registers): Rewrite to actually work, I hope.
2728 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2729 Replace index() with strchr(). Remove all the pre-BFD macro
2730 definitions for accessing the symbol file.
2731 (struct dbx_symfile_info): Encapsulate the information that
2732 dbx_symfile_init needs to pass to dbx_symfile_read in this
2735 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2736 dbx_symfile_discard): Rearrange symbol file reading to divide
2737 the format-specific part from the format-independent part,
2738 leaving the format-independent part such as file name expansion
2739 and opening in symtab.c. This replaces
2740 partial_symbol_file_open and partial_symbol_file_read.
2741 Symbol_file_read, add_file, add_file_target_command,
2742 add_file_addr_command move to symtab.c. Pass an explicit
2743 "mainline" flag for when reading the main symbol table, rather
2744 than relying on the offset address to be zero or nonzero.
2746 (dbx_symfile_read): Don't allow void *'s to be printed as
2748 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2749 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2750 macro" debug version really work.
2751 (read_dbx_symtab): Remove unref'd parameter inclink.
2752 Avoid swapping N_SLINE symbols, for speed.
2753 Merge N_TEXT!N_EXT case with the other external symbol
2754 definitions' case. Add comments.
2755 (start_psymtab): Allocate the symfile name in the psymtab on
2756 the psymbol_obstack, rather than using the caller's storage.
2757 (end_psymtab): Only allocate a dependencies list if there are
2759 (psymtab_to_symtab_2): Use BFD when reopening file to read
2760 its symbols for real.
2761 (read_struct_type): Add FIXME comments where it needs work
2763 (read_huge_number): Add FIXME about overflows.
2764 (read_range_type): Add FIXME about comparing a long to 1<<32.
2766 * coffread.c: Minor changes to move things closer to the new
2767 regime with symtab.c and dbxread.c Major work is still needed
2770 * exec.c (exec_file_command): Remove old variables (see core.c
2772 (xfer_memory): If memory transfer is right at the end of a
2773 section, don't lose.
2775 * findvar.c (get_saved_register): If value is in a real
2776 register, LVAL is lval_register, not lval_memory.
2778 frame.h: Declare print_sel_frame and record_selected_frame.
2780 gdb-int.texinfo: New file, for GDB internals documentation.
2781 Very simple, unformatted doc of cleanups is there for now.
2783 gdbcore.h: Remove obsolete variables that described a.out
2784 section addresses and offsets. (See core.c above.)
2785 Declare fetch_core_registers and registers_fetched.
2787 getopt.c: Declare char *alloca(); even on SPARC.
2789 infcmd.c (run_command): Call target_kill rather than
2791 (step_command, next_command, stepi_command, nexti_command):
2792 Declare from_tty parameter even though we don't use it.
2793 (run_stack_dummy): argument BUFFER is a char array, not
2794 a pointer to REGISTER_TYPE.
2795 (finish_command): using_struct_return needed a value *,
2796 not a struct symbol *.
2798 * infptrace.c (child_xfer_memory): To avoid dependency on
2799 where sections are in memory, try PT_WRITE_D and if that fails,
2800 try PT_WRITE_I. Most Unixes don't care which you use.
2802 * infrun.c (step_resume_break_shadow): Change to array to
2803 match other breakpoint shadow storage.
2804 (clear_proceed_status): Pass address of bpstat to
2805 bpstat_clear, not the bpstat itself.
2806 (child_create_inferior): FIXME comment about if the child
2808 (start_inferior): Remove old function.
2809 (child_open): Use target_kill rather than kill_inferior.
2810 (wait_for_inferior): Ditto.
2811 (insert_step_breakpoint, remote_step_breakpoint): Use
2812 new step_resume_break_shadow.
2814 * inftarg.c (child_wait): If all child processes die,
2815 pretend that the one being waited for exited with signal 42.
2817 * main.c (command_line_input): When scanning for comments,
2818 don't coredump on unclosed quotes.
2819 (quit_command): Use target_kill rther than kill_inferior.
2820 (_initialize_main): Rename class_user from "user" to
2823 * printcmd.c (print_command_1): Initialize "fmt" if no format
2824 is specified by the user.
2825 (print_frame_args): Only add to args_printed if we are
2826 actually fetching args from the stack (avoiding undefined
2828 (_initialize_printcmd): Remove bogus \{ from string.
2830 * remote-eb.c (eb_open): Avoid coredump on no argument.
2832 * remote-nindy.c: Bring out of Intel environment into new
2833 target environment. Remove all conditional compilation on
2834 I80960. Massive hacking throughout.
2835 (nindy_xfer_inferior_memory): New routine stolen from
2837 (nindy_create_inferior): New routine pieced together, probably
2838 not quite working yet.
2839 (nindy_ops): New target_ops struct for nindy.
2841 * remote-vx.c: Use write_memory rather than target_write_memory
2842 to get error checking.
2843 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2845 (vx_create_inferior): Use target_terminal_ours...
2847 * signame.c (_initialize_signame): Always initialize, since
2848 we need the table for things other than psignal.
2850 * solib.c (solib_add): Use symbol_file_add, not add_file.
2851 (solib_address): Return boolean result rather than struct
2852 pointer which nobody else knows the type of.
2854 * sparc-tdep.c, valops.c: Use write_memory rather than
2855 target_write_memory, to get error checking.
2857 * stack.c (locals_info, catch_info, args_info,
2858 get_selected_block, frame_command, up_command): Use
2859 target_has_stack, rather than have_inferior_p or
2862 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2864 * symfile.h: New file, defining the interface between the
2865 generic and object-file-specific symbol reading code.
2867 * symtab.c: Move generic symbol-reading interface to symtab.c,
2868 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2869 table to map BFD targets to symbol-reading modules in GDB.
2870 Change index to strchr.
2871 (lookup_struct_elt_type): Use error() rather than hand-made
2872 simulations thereof.
2873 (lookup_partial_symbol): Speedup slightly when length == 0.
2874 (symbol_file_add): New function.
2875 (symbol_file_command): Call it.
2876 (symfile_open, symfile_init): New function.
2877 (add_file_target_command, add_file_addr_command): moved from
2880 * target.c (target_command): use target_kill.
2882 * target.h (target_files_info): Don't declare, never called
2885 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2886 files to determine stack end address.
2888 * valarith.c (value_x_binop, value_x_unop): Change error message
2889 to be more useful. Pass proper argument to value_struct_elt.
2891 * valops.c (value_assign): FIXME comment that long long
2892 bitfields will break here.
2894 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2895 Update `make saber_gdb' to work better.
2897 * TODO: A woman's work is never done.
2899 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2900 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2901 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2902 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2903 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2904 valops.c, valprint.c, exec.c: Lint.
2907 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2909 Continuing Intel 960 port merge of GDB.
2911 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2912 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2913 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2914 Wack over "make depend" so it handles files in subdirectories
2915 vx-share, nindy-share, bfd, and in the current directory.
2917 * blockframe.c (get_prev_frame_info): Remove fatal error
2918 if stack not defined.
2920 * core.c (core_open, core_detach): New functions that handle
2921 the old "core-file" command as "target core" and "detach" instead.
2922 (core_file_command): Call them.
2923 (core_xfer_memory): Use common routine xfer_memory.
2925 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2926 dbxread now uses bfd for everything but symbol reading itself.
2927 BFD internals are used to drag out the relevant file offsets.
2928 (partial_symbol_file_open): Change args all around for BFD.
2930 * symtab.c: Rename "value" to "val" everywhere, so we can
2932 (symbol_file_command): New command, moved from dbxread.c
2933 and coffread.c. It uses BFD to read the file, then vectors
2934 based on its type, to dbx or coff symbol readers.
2935 * symtab.h: Extern a few vars for symbol_file_command.
2937 * target.h: Breakpoint takes a char * save area, not a char **.
2939 * valprint.c (val_print): When unpacking bitfields, offset
2940 the address in gdb of the value, if it is declared with a shorter
2941 type. Remove the last "runtime kludge test" of host byte order.
2943 * utils.c: Remove old my_bfd_read routine.
2945 * stack.c (frame_info): Use target_has_stack. Print program counter
2946 register's actual name rather than "pc", since it's called the
2947 "ip" (instruction pointer) on the i960 (sigh).
2949 * target.c (target_command): Add command for selecting a target
2950 type and calling its open routine. This is used for initiating
2951 communication with a particular target, in a generic way.
2953 * tm-i960.h: Update for modern gdb. Remove semicolons from
2954 various macros. Handle reading struct return convention, and
2955 error-out attempts to return structs with the "return" command.
2956 Be sure gdb doesn't think we know how to call functions in the
2959 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2960 to i960_xxx in lower case.
2961 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2962 not being defined yet.
2964 * remote.c (remote_open): Call start_remote to initialize
2965 wait_for_inferior during open.
2966 (remote_xfer_inferior_memory): Return length written rather
2969 * remote-vx.c (target_command -> vx_open): Use new generic
2971 * remote-eb.c, inftarg.c, exec.c: ditto.
2973 * infrun.c: Fix comments.
2974 (attach_program -> child_open): Use new generic target command.
2975 (wait_for_inferior): Clear saved register values before target_wait,
2976 so target_wait can set some of them if convenient.
2978 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2979 Return success indicator, not void.
2980 (child_xfer_memory): Avoid fetching initial word if we'll
2981 overwrite it anyway.
2983 * infcmd.c (attach_command): Use new generic target open routine.
2984 (_initialize_infcmd): Update doc on attach and detach commands.
2985 (do_registers_info): Merge in a byte-order problem as a FIXME
2988 * findvar.c (find_saved_register): Avoid problem in current frame.
2989 (read_relative_register): Ditto.
2990 (write_register): Convert byte order on the way out.
2992 * exec.c (file_command): Add.
2993 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
2994 (xfer_memory): Common function between core_xfer_memory and
2996 (exec_xfer_memory): Use it.

3001 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
3002 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
3004 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
3006 Merge Intel 960 port of gdb, continuing...
3008 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
3009 symbol_file_command): Pass from_tty arg to hush 'em up.
3011 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
3012 Add magic numbers for 960 COFF format.
3014 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
3016 Merge Intel 960 port of gdb, from Intel "1.2" release.

3034 More cleanup of batch mode; specifically, execute "-s", "-e", and
3035 "-se" switches as soon as they are encountered on the invocation line.
3037 Fri Apr 20 13:47:15 PDT 1990
3040 Thu Apr 19 09:54:28 PDT 1990
3041 Add 'reset' command.
3043 Wed Apr 18 09:48:07 PDT 1990
3044 After opening remote tty, wait for 1 second to go by without input
3045 from it before trying to talk to NINDY (fixes problems with the
3046 Heurikon HK80/V960E).
3048 Mon Apr 4 16:33:05 PDT 1990
3049 Some output was not being suppressed in 'batch' mode.
3051 Thu Mar 22 15:31:11 PST 1990
3052 Ask user if old symbol table should be deleted when new file is
3055 Allow user to run a program downloaded before gdb960 was brought up.
3057 Correct "exec-file" help message for i80960 context.

3060 corrupt user program.
3062 Make sure to zero low-order bits in rip's because of bug in 960CA
3063 A-step part: could cause operation faults when "next"ing across
3066 Correct bug that made it impossible to get source line numbers for
3067 code loaded at addresses higher than 0x7fffffff.
3069 Wed Jan 10 12:43:22 PST 1990
3070 Open remote tty for exclusive use.
3072 Fri Jan 5 12:14:42 PST 1990
3073 Correct disassembly (CA manual was right after all):
3074 opcode for sysctl is 0x659
3076 Mon Oct 23 12:03:04 PDT 1989
3077 Use G960BASE and G960BIN environment variables to find 'sx' utility.
3079 Mon Oct 16 14:15:09 PDT 1989
3080 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
3082 Mon Oct 2 15:56:31 PDT 1989
3084 Added 960CA disassembly support.
3086 To simplify maintenance:
3087 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
3089 - eliminated opcode.h: incorporates tables into i960-pinsn.c
3090 - moved 960-specific routines from i960-pinsn.c to i960-md.c
3091 - made disassembly interface identical to that in gdmp960.
3095 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
3097 * target.h: Allow targets to stack. Add target_has_memory,
3098 _registers, etc. Restructure memory access and "info files"
3099 to walk the target stack.
3100 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
3101 target.c: Change tables to match target.h.
3102 * inflow.c (child_mourn_inferior): pop child_ops.
3103 (generic_mourn_inferior): Use new has_stack flag.

3105 * inftarg.c (child_files_info): New "info files" regime.
3106 * remote-eb.c: New memory regime, new info files.
3107 * remote-vx.c: New memory regime, new info files. Now use
3108 separate targets for VxWorks attachment to machine, and
3109 actually running a process under VxWorks, since one has
3110 stack & execution & regs and the other doesn't.
3111 * remote.c: New memory regime, new info files.
3112 * sparc-xdep.c (fetch_core-registers): New memory regime.
3113 * target.c: New routines and support for stacked targets,
3114 new memory regime, new info files regime.
3117 Generalize section handling for an arbitrary number of sections,
3118 including use of the new BFD (binary file) library.
3119 * gdbcore.h: Add struct section_table.
3120 * exec.c (build_section_table): Iterate all sections and
3121 record what gdb needs to know about them.
3122 (exec_command): Use it.
3123 (exec_xfer_memory): Use the table.
3124 (exec_files_info): Print the table.
3125 * core.c (core_file_command, core_xfer_memory, core_files_info):
3127 * source.c (find_source_lines): Use bfd_get_mtime.
3128 * dbxread.c: Quick changes to make it compile with new BFD.
3129 * utils.c (error): Avoid using bfd_error in generic routines.
3131 * core.c (core_fetch_registers): Get from the ".regs" section of
3133 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
3135 * inferior.h (attach_flag): Export.
3136 * infcmd.c (run_command): use new target_create_inferior.
3137 * infrun.c (child_create_inferior): Don't return result.
3138 * Makefile.dist (VERSION): 3.91.4.
3140 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
3142 * breakpoint.c (bpstat_num): Handle breakpoints which have
3143 since been deleted, such as temporary breakpoints.
3144 infcmd.c (program_info): ditto.
3146 * core.c (core_file_command): Display the frame where the core
3151 * remote-vx.c (target_command): Merge in target command from
3152 targ-vx.c. A few other cleanups.
3154 * TODO, Projects: Lots more stuff to do...
3156 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
3158 Massive changes to wall off the remote-debugging interface
3159 behind a function vector. The port to handle VxWorks targets
3160 is also part of this.
3162 All files: Replace references to renamed functions,
3163 remove references to remote_debugging, remove references to
3164 have_include_file, have_core_file in favor of target_has_stack,
3165 target_has_memory, etc.
3167 * Modularize the breakpoint interface.
3168 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
3169 a breakpoint instruction.
3170 breakpoint.c: struct breakpoint's shadow_contents now sized as
3172 (insert_breakpoints): Vector to target to install breakpoints.
3173 (remove_breakpoints): Vector to target here too.
3174 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
3175 sparc-tdep.c (single_step): Use new breakpoint interface for
3176 the single-step breakpoints.
3177 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
3178 New file, contains routines to insert and remove breakpoints by
3179 reading out the old contents and later replacing them. This is
3180 how ptrace breakpoints work, and many remote systems as well.
3182 * tm-vxworks68.h: New config file, overrides a few things for
3183 Wind River's preferences.
3185 * target.h: New file, for transfer vector used to talk to the
3186 inferior (child, attached, core, exec, remote, etc). All accesses
3187 to the thing being debugged should come through these vectors.
3188 target.c: New file, routines to handle transfer vector.
3189 (various files): Add transfer vectors XXX_ops for the various
3190 targets and pseudo-targets (core files, etc) we support.
3192 * breakpoint.c (bpstat_stop_status): Further explorations of
3193 watchpoints and why things don't work all the time.
3194 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3196 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3197 the local gdbinit if it doesn't already have it.
3199 * core.c (core_ops): add and install.
3200 Allow core debugging without exec file.
3202 * dbxread.c (free_and_init_header_files): Merge two fns.
3203 (end_symtab): Free named symbol table when a new version comes in.
3204 (read_dbx_symtab): Relocate all kinds of symbols with base
3205 address. First step toward handling different text, data, bss
3207 (add_file_addr_command): Renamed add_file_command.
3208 (add_file_command): Vector to remote handler.
3209 Add "load" as an alias for "add-file" command.
3211 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3212 non-returning functions.
3214 * exec.c: Add exec_ops, and push it as a target when an exec
3217 * infcmd.c (run_command): Pass executable file name and arg list
3218 separately when starting an inferior. Permit "run" when no exec
3219 file is specified, for VxWorks.
3220 (detach_command): Move to child_detach in inftarg.c.
3222 * inftarg.c: New file. Unix-child-specific routines, and the
3223 child_ops structure.
3225 * inferior.h (registers): Export "registers" as the way for
3226 target dependent register handlers to find gdb's local copy of
3227 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3228 since it is now used by places that want wait_for_inferior to
3229 handle the grunge but want to see every trap from the inferior.
3231 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3232 Eliminate remote_debugging hooks in terminal handling.
3234 * infrun.c: Replace start_inferior with child_create_inferior.
3235 Move all the hair of Unix shells and ptrace idiosyncracies into
3236 child_create_inferior, so remote handlers don't have to deal.
3237 Remove running_in_shell. Rename stop_after_attach to
3238 stop_soon_quietly, and use it in a few other places where we want
3239 to just call wait_for_inferior and get control back on the first
3240 trap. trap_expected now never takes a value > 1.
3241 (init_wait_for_inferior): Initialize static vars when a new
3244 main.c (gdbinit): Add new hook for .gdbinit file name, let
3245 it be overridden by config files as GDBINIT_FILENAME.
3246 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3247 Both of these are used for VxWorks gdb.
3249 mcheck.c: rename include file "gmalloc.c" to avoid problems
3250 with system include file "malloc.c".
3252 param-no-tm.h: New include file, same as param.h but does not
3253 include the default "tm.h" file. This is used in files where
3254 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3256 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3258 remote-vx.c: New file, VxWorks remote debugging support. Uses
3259 RPC routines that are shared with the target system, in directory
3262 remote.c: Vectorize remote interface.
3264 source.c: Globalize source_path, and make an alias "l" for "list"
3265 since we now have the "load" command.
3267 sparc-xdep.c: Use new param-no-tm.h.
3269 symmisc.c (free_named_symtab): Add new function from Wind River.
3270 However, ifdef it out for now while we think about what it should
3273 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3275 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3276 non-Unix-children handle this with their own code in the target
3279 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3280 source and target lists. Add vx-share to default list of include
3281 directories. Add new files to src and target lists: mem-break,
3282 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3283 ${srcdir} versions of munch and createtags are used.
3285 * valops.c (find_function_addr): Split out of call_function.
3286 (call_function_by_hand): Rename call_function; this function
3287 calls functions in the target by laboriously patching the target
3288 word-by-word with the right stack, args, regs, etc.
3291 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3293 Handle AMD 29000 a bit better.
3295 * remote-eb.c (readchar): Mask received char log to make it readable.
3296 (remote_start): Pass arguments down to executing program.
3297 Make startaddr unsigned.
3298 infrun.c (start_inferior): Accept args, pass them to
3300 infcmd.c (run_command): Pass args down to start_inferior.
3302 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3303 the target object file format.
3304 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3306 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3307 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3309 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3311 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3312 * TODO: We did a few things, we have more to do though.
3314 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3315 * inflow.c (inferior_died): Clear deferred stores.
3317 * Debug problems with dummy frames and calls to the inferior.

3320 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3321 (sparc_push_dummy_frame): Simplify and fix what we push.
3322 (sparc_pop_frame): Slightly more hair here, deciding whether
3323 we are restoring a saved PC or returning to a return address in %i7.
3324 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3326 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3327 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3328 * obstack.h (chunkfun): ditto.
3329 * defs.h (xmalloc, xrealloc): ditto
3331 * utils.c (quit): Grab the terminal from the child if necessary.
3333 * inflow.c (term_status_command): Rename to term_info, change
3336 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3337 (is_delayed_branch): Speed up.
3338 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3339 Still missing some float ops, and needs testing.
3341 * Support for input and output radixes other than base 10
3342 * defs.h (input_radix, output_radix): Declare.
3343 * expread.y (yyparse, parse_number): Handle changes of input
3344 radix, and ambiguous names-or-numbers in radixes >10.
3345 * printcmd.c (print_scalar_formatted): Print formatted hex
3346 numbers in varying column widths.
3347 * valprint.c (val_print): Use output_format to print scalar ints.
3348 (set_input_radix, set_output_radix, set_radix): Create.
3349 (set_output_radix): Set output_format from output_radix.
3350 (_initialize_valprint): add `set radix' but leave the others off.
3352 * main.c (execute_command): Let stupid questions be turned off.
3353 (_initialize_main): Handle "set stupidity", etc.
3355 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3356 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3358 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3360 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3361 bfd stuff is still screwed up, but with some manual work, it
3364 * breakpoint.c (bpstat_do_actions): Start over if a command
3365 proceeds the inferior, since the inferior will have stopped and
3366 will need to have its new stop-actions taken care of.
3368 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3369 compiler fits, simplify it.
3371 * gdb.texinfo (directory command): Doc new dir command.
3372 source.c (directory_command): "dir" now puts things on the front
3373 of the path, moves dups up front, and handles multiple names
3374 on the command line, inserting each one in order. It also
3375 blows away cached line and full_filename info.
3377 * stack.c (backtrace_command): Skip "more stack frames follow"
3380 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3381 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3382 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3383 The only odd one was Gould NP1, which had defined vprintf to
3386 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3387 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3388 variable, inspect_it.
3389 valprint.c (print_string, val_print): Use the global inspect_it
3390 to indicate whether to print in Epoch style or normal style.
3392 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3394 * printcmd.c (call_command): add an alias for the "print" command
3395 which runs expressions and doesn't print the result if void.
3396 (print_command_1): implement it.
3398 * command.c: Remove #if 0'd code. Initialize all the fields
3399 in add_cmd (). Rename do_nothing_command to
3400 not_just_help_class_command, and make it externally visible.
3401 command.h: add user_commands to struct.
3402 * main.c (define_command): Don't overload c->function with a char
3403 string as well as a function pointer.
3405 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3406 calling convention of value_struct_elt () that got dropped in
3409 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3410 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3412 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3414 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3415 until a good time (e.g. when we are about to run the child),
3416 saving ptrace calls.
3417 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3418 * tm-sparc.h: define DO_DEFERRED_STORES.
3420 * sparc-xdep.c (store_inferior_registers): when storing float
3421 registers, don't store stack regs too. When storing the SP,
3422 however, DO store the stack regs too. This fixes a bug in which
3423 the dummy frame is not recognized when a call_function finishes,
3424 because its frame pointer (in the stack regs) was never
3426 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3427 even though we don't know how to read them from an inferior.
3428 valops.c (call_function): Comment about storing SP.
3430 * infrun.c (save_inferior_status): Save away the original bpstat
3431 chain so it can be restored later. Install the copied version for
3432 use by whoever saved the status. It will be blow away by
3433 restore_inferior_status, and the original chain restored. This is
3434 important for people who have pointers into the original.
3436 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3437 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3438 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3441 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3443 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3444 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3445 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3447 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3449 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3450 Store the baseclasses in a type struct starting from array element
3451 0 rather than from the unusual array element 1.
3453 dbxread.c: the above.
3454 (virtual_context): Add
3455 Read new debug information about which virtual function table
3456 a virtual function is from, and store it in fn_field.fcontext.
3458 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3459 TYPE_FN_FIELD_STATIC_P.
3461 symtab.c: the above.
3462 valops.c: the above. Handle pointer casts of object *'s.
3463 (search_struct_method): Add.
3464 (value_struct_elt): First arg is now a pointer to a value, and is
3467 valprint.c: the above.
3468 values.c (value_virtual_fn_field): Add type arg. Handle
3469 offsetting to the proper object when calling virtual fns.
3471 (baseclass_addr): Add valuep arg.
3473 * README: Document the current state of BFD config (missing).
3474 * TODO, ChangeLog, Makefile.dist: Roll version.
3475 * WHATS.NEW: Add summary of changes since 3.5.
3477 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3479 * dbxread.c (read_struct_type): Clear bit vectors whenever
3481 symtab.c (B_CLRALL): define.
3483 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3484 using == rather than =. Huh... This fixes the dreaded problem
3485 wherein builtin_type_int becomes TYPE_CODE_FLT.
3487 * core.c (info_files): Show the inferior pid.
3489 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3490 already knows how to look in the source directory.
3492 * Remove psymtab hair from many places. Remove duplicated code
3493 for searching symbol tables. Hide psymtabs from most places.
3494 Make it fast to get from a psymtab to its symtab.
3496 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3497 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3498 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3499 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3500 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3501 new symtab completely. New psymtabs get symtab pointer
3502 initialized to zero. Remove MI warning printf.
3503 symtab.h: Comments. Add psymtab to symtab pointer.
3504 (PSYMTAB_TO_SYMTAB): New macro.
3505 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3506 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3508 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3510 (print_frame_info): Avoid special-casing symbols that have not yet
3513 * source.c (open_source_file): Quick path if we have already
3514 located the source file by its full name.
3516 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3517 find_pc_psymtab. When a name is found in the misc function
3518 vector, search the symbol table for its mangled name, not the
3519 name that the user typed.
3521 * bfd.h: Fix missing comment terminators, make #endifs match.
3523 * valarith.c (value_less): Handle unsigned int comparisons.
3524 Add FIXME about pointer compares, which assume host and target
3525 pointers are the same.
3527 * command.c (do_nothing_command): lint
3528 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3529 fix comments on debug symbol format for visibility. Actually set
3530 visibility of symbols.
3531 main.c (echo_command): lint; use <readline/history.h>.
3532 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3533 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3534 pointing past end of allocated memory; saber complains.
3535 obstack.h: Declare the external functions that we use.
3536 valarith.h: use <string.h>
3537 solib.c (solib_add): lint.
3539 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3541 * main.c (initialize_main): Default info_verbose to off, now that
3542 symbol reading is fast.
3543 (quit_command): Avoid clobbering exec_bfd while quitting.
3545 * Initial BFD (binary file diddling library) merger:
3546 coffread.c: Change AOUTHDR to struct exe_hdr.
3548 core.c: initialize initialized data at compile time.
3549 (core_file_command): Move from coredep.c, convert to bfd.
3550 (xfer_core_file): Convert to bfd.
3551 exec.c (exec_file_command): use bfd routines.
3553 mips-tdep.c: Remove exec_file_command and friends.
3556 * coredep.c: (fetch_core_registers) Convert core_file_command to
3557 fetch_core_registers.
3558 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3560 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3561 (my_bfd_read): More bogosity, which I don't think we call.
3562 (program_name): Remove this atrocity asap!
3564 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3567 values.c: allocate_repeat_value was not clearing the
3568 optimized_out field.
3569 (value_static_field): minor stylistic fix (wrong macro was used).
3570 valops.c (value_struct_elt_for_address): didn't work for C++
3573 * signame.c (_initialize_signame): Initialize signal names once.
3575 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3576 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3577 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3579 * remote-eb.c: Support user-settable baud rates on the serial port.
3581 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3583 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3585 * tconfig/sun3os4: Remove warning about native assembler,
3586 since it also occurs in the xconfig file.
3588 * findvar.c (registers): Allocate some slop after `registers'
3589 to prevent stray accesses from trashing the next variable.
3591 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3592 on the sun-3, by changing the #ifdef from `sun3' (which is not
3593 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3594 vars, which happened to follow `registers' in the executable.
3596 * readline/history.c (history_search): Heed gcc-2's advice
3597 and parenthesize && inside ||).
3599 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3600 tm-29k.c: Insert FSF copyright headers.
3602 * remote-eb.c: Better comments.
3604 * Makefile.dist: Update to 3.91.6.
3605 * TODO: note PREPARE_TO_STORE problem.
3607 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3609 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3611 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3613 * infrun.c (wait_for_inferior, at end): Don't set up
3614 prev_* if the inferior no longer exists.
3616 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3617 CANNOT_EXECUTE_STACK.
3618 valops.c (call_function): Use it.
3620 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3622 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3623 infrun.c (wait_for_inferior, 2 places): Use it.
3625 * values.c (value_being_returned): Only use
3626 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3628 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3629 right thing for remote-eb.c.
3631 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3632 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3634 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3635 (FRAME_FIND_SAVED_REGS).
3637 * findvar.c ({fetch,store}_registers): Check for
3638 REMOTE_{FETCH_STORE}_REGISTER macro.
3640 * findvar.c (get_saved_register): Add argument lval and
3641 change meaning of argument addr.
3642 findvar.c: Change calls to get_saved_register to reflect
3643 new calling convention.
3644 valops.c (value_assign): Use get_saved_register instead of
3645 find_saved_register.
3647 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3649 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3650 an (uninitialized) pointer to one. Use "&" when passing it
3653 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3655 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3658 * coffread.c (symbol_file_command): Put semicolon after
3660 Put safe_to_init_tdesc_context in #if defined (TDESC).
3661 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3662 coffread.c: #include <sys/stat.h>.
3663 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3664 Add missing ')' in check for "lc%" and friends. Remove
3666 Declare read_one_sym() at top of file.
3667 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3668 MC68WRMAGIC can have the same value without causing a duplicate
3671 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3673 * Allow a Makefile to be built without building the
3674 tm and xm file links that screw up builds in subdirectories.
3675 This is done with `config.gdb none', then you can do things
3676 like `make gdb.tar.Z'.
3677 * tconfig/none: Config file for no target system
3678 * xconfig/none: Config file for no host system
3679 * config.gdb: If no TM or XM files are called out by the
3680 host or target file, don't make links for them.
3682 * cplus-dem.c: Add documentation.
3684 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3685 simple error, so the user's gdb doesn't crash due to some object
3686 file problem (e.g. somebody is rebuilding the file out from under
3689 * printcmd.c (print_address_symbolic): demangle the symbol.
3691 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3692 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3693 (alldeps.mak): sort and uniq all results from this; duplicates
3694 hose gdb.tar.Z link building. Remove RCS files from
3695 tconfig and xconfig. Add config files for sun386. Add
3696 a few odd files to OTHERS and HFILES.
3698 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3700 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3701 Roll version number to 3.91.5. Make lint work in bindir.
3703 * README: Document cross-debugging and new file structure.
3705 * blockframe.c: Lint. Include "value.h" to declare read_register.
3706 (find_pc_partial_function): remove duplicate line.
3708 * command.h: Lint. Declare error_no_arg and dont_repeat.
3710 * tm-news.h: Remove inadvertently duplicated stuff.
3712 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3713 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3715 * config.gdb: Allow `config.gdb host target' form. Clean
3716 up previous change that printed bogus messages when you just said
3719 * core.c: #include "command.h" for lint.
3722 * main.c: Remove some casts of enums. Lint.
3729 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3731 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3732 read it from memory. This will allow us to save ptrace calls
3733 eventually. Changed caller single_step too.
3735 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3736 that we aren't going to use, saving many ptrace calls, especially
3737 when watchpointing or single stepping. Use some #define's for
3739 (store_inferior_registers): Ditto.
3740 (core_file_command): Use some #define's for constants.
3742 * tm-sparc.h: Add #define's for some register numbers, so we
3743 can eliminate the use of random constants in sparc-xdep.c.
3745 * stack.c (frame_command, print_frame_info, up_command,
3746 down_command) Remove frame_changed, since it
3747 causes a bug and doesn't seem to do anything useful. In some
3748 places it was used as a flag, in others as a stack level (?).
3750 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3751 default is to use the portable (vprintf) version rather than the
3753 * xm-news.h (MISSING_VPRINTF): Add.
3755 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3757 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3759 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3760 about linking debugged programs -Bstatic in the sun?os4 config
3761 files in tconfig and xconfig subdirectories.
3763 * main.c (main): Remove unreached exit(0) now that we exit
3766 * Create TODO file for online bug list. There are too many
3767 "little" bugs to keep track of on paper.
3769 * Change Projects file to refer to bug-gdb@cygnus.com
3770 rather than kingdon@ai.
3772 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3774 * Makefile.dist (VERSION): 3.91.4 now.
3776 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3777 (condense_misc_bunches): Add sanity check that misc_count is
3778 the same as the number of symbols in the bunch.
3780 * coffread.c: rename init_misc_bunches. Pass an argument
3781 to condense_misc_bunches (a zero).
3783 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3784 every time we are called; don't rely on our caller to do it.
3785 (add_file): Remove call to init_misc_bunches.
3787 * mipsread.c: Only warn, don't error, if unknown symbol types.
3788 This keeps an old gdb from falling on its face if it sees newly
3789 extended symbol info. Rename init_misc_bunches.
3791 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3793 * Merge in changes from Per Bothner for DECstations and other
3794 MIPS stuff. The rest is Bothner speaking:
3796 The next message is a merger of Alessando Forin's mips port with
3797 mine. I've tried to use my good if biased judgment to get
3798 the best of both. It *does* need testing.
3800 Some of the changes are general, *not* mips-specific.
3803 Didn't believe in little-endian bit order.
3804 There are still inconsistencies about whether flags
3805 like BITS_BIG_ENDIAN are integer (#if ...) or
3806 boolean (#ifdef ...). I tried to paper over them.
3808 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3809 Moved some misc_function code that was common to
3810 {dbx,coff,mips}read.c to symtab.c.
3811 In the process, I think I cleaned things up a bit.
3812 At the same time, moved obsavestring and obconcat to symtab.c.
3815 Removed obsolete condense_addl_misc_bunches (use
3816 condense_misc_bunches(1) instead).
3819 Needed to include <sys/dir>, at least on DECstations.
3821 valops.c, mips-tdep.c, tm-mips.h:
3822 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3823 conventions (when STACK_ALIGN is insufficient).
3824 Needed on mips, where doubles need 8-byte alignment,
3825 but ints only need 4.
3828 Removed cruft that was not being used.
3829 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3832 Print $ before register-names (I think that makes things a little
3834 Never print two instructions, even if one delays.
3835 Removed hex-disassemble set_cmd. (This is not mips-specific,
3836 so I think the argument is whether it is generally worthwhile or not.
3837 I'm inclined to think not, given how easy it is to
3838 convert between radixes in gdb.)
3841 This is basically Alessando's code.
3842 It doesn't use obstacks; I changed it to use obstacks
3843 in a few minor places where using malloc causes a
3844 memory leak. (Probably, more places could/should be changed.)
3845 I added record_misc_function where it was missing.
3846 In symbol_file_command and add_file_command, I tried
3847 to make the code consistent with more recent versions.
3848 Minor sylistic changes in parse_procedure.
3849 Make a .gdbinfo. psuedo-symbol point back to the real
3850 procedure symbol (using the isym field).
3853 This is basically from my port, but with a lot of details
3854 and a number of routines merged in from Alessando's version.
3855 I basically used my code "raw" backtrace (use heuristics
3856 from the actual code, rather than symbol table info) - though
3857 the idea is Alessandro's. I feel my code is a little cleaner
3858 here, particularly in being a little more flexible, such as being
3859 able to handle gcc-produced code (which it now can).
3860 It also doesn't do frame caching (which is not useful
3861 more recent gdb versions).
3862 I also used my code for push_/pop_dummy, more or less.
3863 I tried to incorporate AF's code for testing sigtramp
3864 while backtracing; I probably got it wrong.
3865 Added mips_print_register, which tries to scrunch as much
3866 information as possible on a screen...
3867 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3868 under mips-pinsn.c), I don't see anything mips-specific here,
3869 and I don't see it being all that useful anyway.
3872 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3873 Use more register names (rather than hard-cases numbers).
3875 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3877 * Hack up 3.90.11 changes:
3879 * Makefile.dist (depend): parameterize $(GCC).
3880 Add solib.c and solib.o.
3881 (readline): Fix vpath for both absolute or relative SRCDIR.
3883 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3884 Also, let the part I didn't understand at least compile so
3885 I can test the rest. FIXME.
3887 * dbxread.c: Fix thinko using strcmp.
3888 (init_psymbol_list): declare static.
3889 (partial_symbol_file_open): Comment cleanups better, avoid
3890 cleaning up the string table since the caller will do that.
3891 Move the stat for mod time into symbol_file_command, temporarily.
3892 (There should be a mod time for each symbol file, eventually,
3893 to control its rereading. FIXME.)
3895 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3896 SunOS, which gives error for shared libs otherwise. (From
3897 Schaefer, probably FIXME needs work for portability.)
3899 * solib.c: Move #include "param.h" to work.
3900 Lowercase all the Uppercase Letters In the Messages.
3901 (find_solib): Clean up inferior_so_name for debug printouts.
3902 Allow no argument, to mean all shared libraries.
3904 * symmisc.c: include param.h to get CLEAR_SOLIB.
3906 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3908 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9

3939 blockframe.c (find_pc_partial_function): If a non-text symbol
3940 is found, set *address = pc - FUNCTION_START_OFFSET.

3948 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
3949 (record_misc_function): Give correct type for N_DATA symbols.
3950 (condense_misc_bunches): do "misc_function_count = j" regardless
3952 Take code which is shared between symbol_file_command and
3953 add_file_command and put it into partial_symbol_file_{open,read}.
3954 Split add_file_command into add_file_command and add_file.
3955 Make psymtab_to_symtab read in the string table if the file
3957 Two new parameters to read_dbx_symtab and start_psymtab.
3958 tm-sunos.h: New file.
3960 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

3975 as necessary, not just once.
3977 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3979 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3981 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3983 * tm-news.h: Add CALL_DUMMY_*.
3985 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
3987 * config.gdb: In list_host, list_target, use ${i}, not $i.
3989 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3991 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
3993 * sparc-opcode.h: Change all store floating-point state register
3994 instructions to have the right match & lose fields.
3996 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3998 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
4000 config.gdb: If srcdir != ., create readline directory and
4001 copy a makefile into it.
4003 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
4004 consistency with POSIX.
4006 * breakpoint.c (bpstat_stop_status): Disable watchpoint
4007 when we exit its exp_valid_block.
4009 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
4011 * Makefile.dist: Bump version to 3.91.3.
4013 * Clean up handling of breakpoint commands (somewhat).
4014 Prompted by Tiemann bug report "cont 10" doesn't work any more.
4016 inferior.h: Add breakpoint_proceeded to inferior status struct
4017 and globals; save it and restore it.
4018 (clear_breakpoint_commands): Cleanup, remove old #define.
4020 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
4021 (save_inferior_status, restore_inferior_status): handle it also.
4022 (proceed): Remove earlier code that set breakpoint_proceeded.
4023 It is now set only in clear_proceed_status.
4024 (clear_proceed_status): Cleanup, use bpstat_clear rather
4025 than clear_breakpoint_commands. No callers need the stop_bpstat
4026 between clear_proceed_status and proceed.
4028 infcmd.c: Add breakpoint_proceeded definition and comment.
4029 (cont_command, jump_command, signal_command): Move call to
4030 clear_proceed_status right next to call to proceed.
4032 breakpoint.c (bpstat_do_actions): Avoid clobbering our
4033 caller's argument while running down the chain of breakpoints.
4034 Use new variable "breakpoint_proceeded" to determine when
4035 a command that it executes moves the inferior past the
4037 (bpstat_clear): Handle NULL argument.
4038 (bpstat_clear_actions): Avoid useless call to
4039 breakpoint_auto_delete.
4040 (delete_breakpoint): Clean up bpstat's that are pointing to
4041 the deleted breakpoint from the stop_bpstat chain.
4042 (breakpoint_auto_delete): Simplify.
4044 * Clean up handling of EOF, error on stdin, etc. This was
4045 prompted by a network problem that caused gdb to go into an
4046 infinite loop filling up its malloc'd memory.
4048 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
4049 not clear_breakpoints_commands, which is now gone.
4050 (main): If command_loop returns (e.g. from EOF on stdin), do
4051 a quit_command (looping back to command_loop if quit_command
4052 doesn't really quit).
4053 (command_loop): check result from command_line_input and
4054 exit if it returns NULL, rather than passing the NULL to
4056 (gdb_readline): Free malloc'd result space before returning
4059 * utils.c (query): Handle C-d to mean "yes", just as if the
4060 input was not a terminal. Also avoid infinite loop if EOF
4061 occurs in mid-input-line before newline. This allows
4062 query to be used at EOF on stdin with reasonable results.
4064 * infrun.c (proceed): Set breakpoint_proceeded.
4066 * values.c (value_as_long): Avoid infinite recursion for enums.
4067 (_initialize_values): Fix typo in help msg (kingdon).
4069 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
4070 RL_LIB for linking. This allows -lreadline for linking
4071 and nothing for dependencies, once readline is a real library.
4073 * config.gdb: Jim Kingdon: give useful error message if the
4074 host or target type is not recognized.
4076 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
4077 it just defines it. Dumb, but deal with it.
4079 * Jim Kingdon suggests:
4080 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
4082 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
4084 * Makefile.dist (VERSION): Bump version # to 3.91.2.
4086 * Clean up Bothner's changes.
4088 * blockframe.c (clear_pc_function_cache): New function.
4089 * blockframe.c: remake cache_pc_function_* static.
4090 * dbxread.c (symbol_file_command): remove references to
4091 cache_pc_function_* variables.
4092 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
4093 * printcmd.c: Avoid kludging a global variable (addressprint)
4094 to avoid printing the address of a string twice. Instead,
4095 pass the format letter 's' down low enough that it can be seen
4096 to avoid this problem.
4097 (print_formatted): Pass format arg to value_print.
4098 (restore_addressprint): Remove function.
4099 (do_examine): Avoid hacking addressprint, cleanups and such.
4100 (print_frame_args): Add a comment to a Bothner change.
4101 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
4102 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
4103 to wipe out the values cached in blockframe.c.
4104 * symtab.c (find_method): Add comment saying how big you must
4105 allocate to be "big enough". Per being terse again.
4106 * valprint.c (val_print): Handle format letter "s" to print
4107 strings without addresses. Add comment to vtbl printing code
4108 which casts with wild abandon. Rearrange reference-printing
4110 @0xaddr: value (print w/addressprint)
4111 value (print w/~addressprint)
4112 @0xaddr (parameter lists w/addressprint)
4113 or nothing (parameter lists w/o addressprint)
4115 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
4117 * Merge more changes from Per Bothner:
4119 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
4120 annoying) that I tried to improve it. Here are my suggestions.
4122 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
4125 Do automatic de-reference when taking the address of a reference.
4127 Don't deref_ref when printing parameter lists.
4129 More attempts at treating refernences properly.
4131 In val_print, if deref_ref==0, don't print dangling " = ".
4133 Add COERCE_REF macro, which de-references an REF.
4135 * Merge changes from Per Bothner:
4137 * Fixed (Sony news)-specific configuration problems.
4138 * Fixed other problems with using vanilla pcc and libc (enum problems;
4139 assumption that vsprintf exists).
4140 * Some major speed-ups (finc_pc_partial_function now caches a match;
4141 parsing avoids duplicate symbol_lookup calls).
4142 * Changed handling of baseclasses (no longer use baseclasses field
4143 of struct type, use the first n_baseclasses fields instead).
4144 * Various minor changes/fixes, most C++-related.
4147 Cache the most previous match from find_pc_partial_function.
4148 (Save both low and high ends of matching function's pc range.)
4149 This speeds up the loop of infrun.c:wait_for_inferior quite
4150 a bit, and makes step/next commands much zippier.
4152 Added an enum->int cast (otherwise, some compilers barf).
4154 No longer set baseclass offset to 0, since multiple
4155 inheritance now mostly works.
4156 Added a number of casts, to shut up compiler warnings
4157 (after stabs where made enums, not ints).
4158 When discarding a symbol table (in symbol_file_command),
4159 must clear the cache introduced in blockframe.c.
4160 Don't convert $vtbl_ptr_type to vtbl any more.
4161 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
4162 Mask off sign bit emitted by g++ for virtual table offset.
4163 Set voffset to -1 (not 1) for static member functions.
4165 Changed parsing/lexing of names to avoid doing symbol lookup twice
4166 (once when lexing to determine symbol class, once for real).
4167 Now only call symbol_lookup once. Fields of 'this' win especially big.
4169 Subpress printing addr twice in the case of 'x/s addr'.
4171 lookup_basetype_type is no longer used.
4172 Add find_methods as recursive helper function to decode_line_1.
4173 This allows multiple inheritance to work.
4174 Also, once one or more matches has been found, do not look in
4175 base-classes. (Baseclass methods would be overridden, anyway.)
4177 Removed baseclasses array in struct type.
4178 Instead of using baseclasses[i], use fields[i-1].
4179 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
4180 Changed sign convention of voffset (previous was inconsistent).
4182 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4184 Used to assume existence of vsprintf. Re-written to not need it
4185 if HAVE_VPRINTF is undefined.
4187 typecmp was too pessimistic. Made it less so.
4189 Don't print space after address.
4190 If vtable points to a misc symbol (with 0 offset), print it,
4191 since that indicates the actual class of the object.
4192 Changed ype_print_derivation_info to use new inheritance
4193 scheme (without baseclasses vector).
4195 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4196 Also, changes needed because TYPE_BASECLASSES were removed.
4198 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4200 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4203 If there is no path set, and the symbols don't indicate what directory
4204 a file was compiled in, look in the current directory. But either
4205 a path or a known compilation directory will prevent this.
4208 Three independent bug fixes:
4209 * Remove the #if 0 block that breaks some stuff.
4210 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4211 adapt gdb to either SunOS 4.0.* or 4.1.
4212 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4215 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4218 (type_print) Demangle the name being printed.
4219 (type_print_base) Handle botched demangling without coredump (tiemann).
4222 (check_stub_method): Document routine.
4223 (tiemann) fix bug for no-arg functions
4224 Avoid clobbering beyond end of malloc'd storage.
4225 Terminate the argument list properly.
4227 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4229 * Changes merged by John Gilmore:
4232 In breakpoint_1, use new print_address_symbolic instead
4233 of find_pc_partial_function. (This forces use of assembler-level
4234 addresses, and avoids misleading non-mangled source-level names.)
4236 Generalize ansi argument such that -1 means skip arglist totally.
4237 Removed global variable print_ansi_qualifiers (which made
4238 code non-reentrant), in favor of extra explicit arguments
4239 to internal routines.
4241 Add new helper function print_address_symbolic.
4242 Use find_pc_misc_function instead of find_pc_partial_function
4243 (since we want assembler-level symbols here).
4245 Print unknown function as just "f (...)", not "f (...) (...)".
4246 Use new fputs_demangled explicitly.
4248 Fixed a typing violation (problem: value.h cannot be imported
4249 without renaming many variable in this file).
4250 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4251 decode_line_1: Moved forward some never-reached code.
4252 Made decode_line_2 skip function prologues correctly.
4254 fputs_filtered should not demangle by default.
4255 Add new fputs_demangled to demangle on demand..
4257 Change value_struct_elt to use value_primitive_field (using recursive
4258 utility function search_struct_field). This allows foo.bar to work
4259 for multiple inheritance (so far only for data fields).
4260 Change check_field in the same way (recursive helper function
4261 to support multiple inheritance).
4262 (Note: there are more of these problems that I haven't fixed.
4263 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4264 value_of_this: 'this' symbol name is now just "this", note "$this".
4266 Don't print static members.
4267 Avoid printing "members of <type>" if there are none.
4268 Simplified type_print_derivation_info by merging duplicate code.
4269 Remove useless blank lines in type_print_base (ptype command).
4271 Added declaration of new routine value_primitive_field.
4273 Added value_primitive_field which is generalized version of
4274 value_field that can handle multiple inheritance (non-zero offsets etc).
4275 Re-implemented value_field to call value_primitive_field.
4277 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
4279 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4280 delete the whole environment. Karl Berry reported the bug.
4281 * source.c - fix openp to avoid //'s in filenames, which
4282 trigger an Emacs bug causing it to not be able to find files
4283 when running gdb in a window.
4284 * dbxread.c - zap the #if 0 that botches the add-file code.
4285 It seems to work a lot better without all the code commented out.
4287 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
4289 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
4292 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
4294 * Makefile - added a ${CFLAGS} to a couple of entries,
4295 added remote-sa.sparc.c
4296 * added remote.sa-sparc.c, a modification of remote.c
4297 which conducts a dialog directly with the SparcStation prom.
4298 * breakpoint.c, infrun.c, sparcdep.c added
4299 remote_insert_breakpoint(), and remote_remove_breakpoint()
4300 to breakpoint.c instead of directly writing breakpoint instructions.
4301 * sparcdep.c on remote_debugging,there is no need
4302 to remove signle step breakpoint instructions.
4303 * main.c added "-epoch" flag and "int epoch_interface" to main.c
4305 * printcmd.c - epoch interface sends lisp expressions to open up
4306 epoch windows on inspection.
4307 * valprint.c - added arrayprint, and addressprint and made adding
4308 format controls easier
4309 * wait.h added a couple of undef's because we were getting
4310 complaints about WSTOPSIG and WTERMSIG begin redefined.
4313 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
4315 * symtab.c (decode_line_1): Add support for handling method stubs
4316 in the type information.
4318 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
4320 * values.c (baseclass_addr): Run loop from INDEX+1 to
4321 N_BASECLASSES; otherwise, we can still get into a loop.
4322 @@ This should be restructured to use a cleaner search strategy.
4324 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
4326 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
4327 abbreviation "Tt" for tags which have the same name as their
4330 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
4332 * symtab.c (list_symbols): add ability to set breakpoints on all
4333 the functions which match a particular regular expression.
4335 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
4337 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
4338 should print ANSI qualifiers (such as `const' and `volatile').
4339 All callers changed to call with ANSI == 1, except from
4340 `check_method_stub', which uses old-style syntax.
4342 * symseg.h (struct fn_field): Remove unneccessary `args' field.
4343 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
4345 * values.c (check_stub_method): New function.
4347 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
4349 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
4350 * valprint (type_print_base): Ditto.
4352 * symtab.c (gdb_mangle_typename): New function.
4354 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
4356 * breakpoint.c (catch_command): New function. Provides a
4357 mechanism to set breakpoints based on catch clauses.
4358 (disable_catch): Similar, but disables breakpoints on catch
4360 (delete_catch): Similar, but deleted breakpoints on catch clauses.
4362 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
4364 * blockframe.c (blockvector_for_pc): New function.
4365 * blockframe.c (block_for_pc): Changed to call
4366 `blockvector_for_pc' and get the block itself.
4368 * stack.c (catch_info): New function. Prints info about
4369 exceptions which can be caught in the current frame.
4370 * stack.c (print_frame_label_vars): New function. Similar to
4371 `print_frame_local_vars'.
4372 * stack.c (print_block_frame_labels): Prints out labels that are
4373 defined in this frame. These labels are exceptions that can be
4376 * dbxread.c: Updated to handle N_CATCH symtab types.
4378 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
4380 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
4381 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
4382 when printing the type.
4384 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
4386 * valprint.c (val_print): Use `baseclass_addr' to access the
4387 baseclasses pointed to via the derived class object at VALADDR.
4389 * values.c (baseclass_addr): New function. Casts derived pointers
4390 to baseclass pointers taking virtual baseclasses and multiple
4391 inheritance into account.
4393 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4397 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4399 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
4400 exp_valid_block field correctly.
4402 * infrun.c (wait_for_inferior): When checking "don't even think
4403 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
4404 also check step_resume_breakpoint.
4405 Insert breakpoints and continue (not step) if
4406 step_resume_break_address != NULL, even if another_trap.
4407 If trap_expected and we enter sigtramp, then set up a
4409 If trap_expected is set when we hit the step_resume_break,
4411 When calling resume and trap_expected says tell resume to step
4412 (2 places), also check step_resume_break_address.
4414 * infrun.c (wait_for_inferior): Don't set
4415 prev_{pc,sp,func_{start,name}} before calling wait ().
4416 Do set them after exiting loop.
4417 Move their declarations outside functions.
4418 (start_inferior): Initialize them.
4420 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4422 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
4423 Restore old code which distinguishes between trap_expected and
4424 running_in_shell, just make the latter take any non-TRAP signal,
4427 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
4429 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
4430 xconfig/3b1 (CC,PINSN_CC): Define.

4449 (printf_command): Add from_tty parameter.
4451 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
4453 * value.h: Add optimized_out field and change lazy field to
4454 char. Add macro VALUE_OPTIMIZED_OUT.
4456 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
4457 instead of stuffing things in buffers (oappend, etc).
4459 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
4460 execute_command, exit both loops.
4462 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
4464 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4466 * Makefile.dist (RAPP_OBS, rapp),
4467 rgdb.c, rserial.c, rudp.c, serial.c, udp.c, xdep.h,
4469 m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
4471 * valops.c (value_struct_elt), values.c (value_static_field):
4472 Change error messages to remove references to `info methods'.
4474 Tue Apr 24 10:25:10 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4477 infrun.c (start_inferior): Add START_INFERIOR_HOOK.
4478 infcmd.c [SHIFT_INST_REGS]: New code.
4479 findvar.c (read_relative_register_raw_bytes): Return a value.
4480 infcmd.c (do_registers_info): Check value from
4481 read_relative_register_raw_bytes.
4483 * command.c (delete_cmd): Free the struct cmd_list_element(s)
4486 Mon Apr 23 10:42:21 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4489 findvar.c (get_saved_register): New function.
4490 findvar.c: Rewrite code which called find_saved_register to
4491 call get_saved_register instead.
4493 Sun Apr 22 14:47:51 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4495 * valprint.c (val_print): Change error message printed when
4496 the type has TYPE_FLAG_STUB set.
