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

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

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

1089 defined, define it to '$'.
1091 * arm-opcode.h: New file (same contents as before; it had
1092 just been left out of the distribution for a long time).

1163 New function to give correct error message.
1165 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

1168 target.c: Add target_preopen and target_command.
1170 (add_target): Call add_cmd and mess with targetlist->doc.
1171 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
1172 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
1173 Call target_preopen from open routine.

1197 * symmisc.c (same): same.
1198 (free_symtab): Make non-static.
1199 * symtab.h (free_symtab): Declare as exported void fn now.
1200 * dbxread.c (end_symtab, end_psymtab): Change comments.
1201 (initialize_dbxread): Call dbx_new_init() in case the first
1202 command is add-symbols.
1203 * target.c (dummy_target): Permit add_syms_addr_command.
1205 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1207 Permit symbols to be superseded when new symbol files have
1208 been read in, particularly for VxWorks.
1210 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
1211 to the main file, as well as to include files. Also, put global
1212 functions into the global psymtab, to make "i fun" work.
1213 (end_psymtab): Free named symtabs and psymtabs for a file, once a
1214 new psymtab for it has been read.
1215 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
1216 a file, once a new symtab has been read for it.
1217 * mipsread.c: FIXME. We need to do the same for MIPS, but it
1218 looks harder to determine the top-level block before it's been
1219 queued to the psymtab list.
1221 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
1222 If we have wiped out any old symbol tables, clean up at end of
1224 (symbol_file_command): Don't reference symfile_fns if it's zero.
1226 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
1227 defines for the blocks of a blockvector that contain global and
1228 file-static symbols and the first of the smaller scope contours.
1229 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
1230 decode_line_1, make_symbol_completion_list): Use the above.
1231 * coffread.c (end_symtab, patch_opaque_types): Ditto.
1232 * dbxread.c (end_symtab): Ditto.
1233 * expread.y (block): Ditto.
1234 * mipsread.c (throughout): Ditto.
1235 * symmisc.c (free_named_symtabs): Ditto.
1237 * symtab.c (list_symbols): Process the first symbol of the
1238 static psymbols list.
1239 (types_info): Restore this function from its untimely #if 0.
1240 It's not perfect, but it is better than nothing.
1241 (_initialize_symtab): Restore "info types".
1243 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1245 * m68k-stub.c: Remote stub for 680x0's, created from
1246 rem-m68k.shar (which is removed).
1247 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
1248 Remove RCS log stuff now that we use CVS and it blows our diffs.
1250 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1252 * symmisc.c (free_named_symtab): Make it work, in its current
1253 kludgy fashion. Change result to indicate if we blew away bkpts.
1254 * dbxread.c (end_symtab): Accumulate result from
1255 free_named_symtab and print warning if we blew user's state.
1256 * symfile.h: free_named_symtab now returns an int.
1258 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1260 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
1261 is the first symbol read, even if not mainline.
1262 (dbx_psymtab_to_symtab): symfile might be zero, cope.
1263 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1264 (set_section_command): New command ("section xxx yyy" -- should
1265 be renamed to "set section xxx yyy" FIXME) which sets the
1266 base address of a section of the exec file, overriding the
1267 virtual address that BFD reports.
1269 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1271 * exec.c: Add add_syms_addr_command to exec_ops, so you can
1272 load symbols at any address while examining an exec file.
1274 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1276 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1277 for printing the float info is host-dependent, not
1278 target-dependent. FIXME.
1279 * i386-pinsn.c: Move #includes to top, remove useless ones.
1280 * i386-tdep.c: Don't bother including <.../reg.h> since we
1281 don't use it (and it doesn't exist on host systems).
1283 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1284 Convert negative numbers properly.
1285 (ieee_test): Make numbers really random; fix format arg.
1287 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1288 * core.c (core_detach): Unpush core_ops, which might not be on
1289 top. We used to just pop the top, which broke things. Don't
1290 need dont_repeat() any more.
1291 (core_file_command): Psst! Don't repeat it.
1292 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1293 * expprint.c (print_subexp): Avoid switch fallthru on
1294 BINOP_ASSIGN_MODIFY, so we can print += and such.
1295 * frame.h: Fix typo.
1296 * inflow.c (kill_command): After killing inferior, print our
1297 current frame in the core file, if we have one.
1298 (generic_mourn_inferior): When inferior dies, either select
1299 the current frame (in the new target, e.g. core file), or
1300 set both the current and selected frames to NULL.
1302 Changes from Peter Schauer.
1304 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1306 * Make all file names fit in 14 characters (sigh and damn!):
1307 mv hp300hpux-xdep.c hp300ux-xdep.c
1308 mv symmetry-xdep.c symm-xdep.c
1309 mv symmetry-tdep.c symm-tdep.c
1310 mv convex-opcode.h convx-opcode.h
1311 mv tm-vxworks960.h tm-vx960.h
1312 mv tm-vxworks68.h tm-vx68.h
1313 mv Makefile.srcdir Makefile.sdir
1314 mv gdb-int.texinfo gdbint.texinfo
1315 mv remote-sa.m68k.shar rem-m68k.shar
1316 mv remote-multi.shar rem-multi.shar
1317 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1318 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1319 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1322 * command.c (user_info_1, user_info): New command for listing
1323 the user-defined commands.
1325 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1327 * dbxread.c (really_free_pendings): Clear file_symbols
1328 and global_symbols after freeing them; otherwise, running
1329 this function twice (if it appears twice on the cleanup
1330 chain), we try to free things twice.
1332 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1333 based on text_addr (the address of text in core), not on addr (the
1334 offset between text in the .o file and in core). This change
1335 is from Peter Schauer.
1337 * main.c: Define ALL_CLEANUPS as a cast of zero.
1338 (return_to_top_level): Use it.
1339 (main): Do all cleanups after each command run as part
1340 of the gdb startup sequence. Also do all cleanups before
1341 entering the command loop, and every time we exit the command
1342 loop and reenter. Before, the cleanups from the startup sequence
1343 were being left undone until the first error!
1344 (command_loop): Rename do_nothing cleanup to command_loop_marker
1345 so we can see it easily when examining the cleanup chain.
1346 (init_signals): Add another do_nothing for signal handling.
1347 (quit_command): Only try to kill target if it has execution.
1348 Problems in the target stack got us into a state where
1349 inferior_pid was nonzero but none of the targets had execution.
1350 In this state you couldn't exit gdb.
1352 * dbxread.c: Two changes from Peter Schauer.
1353 (echo_command): Fflush output after an echo command.
1354 (show_history): Pass all args to cmd_show_list.
1356 * utils.c (init_malloc): Call mtrace to turn on tracing
1357 if the environment variable MALLOC_TRACE is set to a file name.
1358 * mtrace.c: Add source file which provides a log of every malloc,
1359 free, and realloc to a trace file.
1360 * mtrace.awk: Add source file which analyzes the trace file.
1361 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1362 (VERSION): Roll to 3.94.3.
1364 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1365 (check_duplicates): Don't bother with watchpoints.
1366 (set_raw_breakpoint): Comment about danger of this routine.
1367 (watch_command): Parse and eval all args before calling
1370 * solib.c (find_solib): Avoid error in referencing memory to
1371 see if any more shared libraries have been added. This is
1372 particularly useful if the target has terminated. Bug reported
1375 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1376 in bringing up 3.94.2 on the Sun-3.
1378 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1379 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1380 expression (in scope) before reenabling watchpoint.
1381 * signame.c (init_sigs): Add missing declaration of i, fix
1382 sys_siglist declaration.
1383 * source.c (list_command): Fixed range computation to use
1385 * stack.c (backtrace_command): Do not allow command if target has
1386 no stack, print informative error message.
1387 * target.c (target_command): Do not write into command line
1388 because this fails if the target command is used in a user defined
1389 command. [This change was enhanced by gnu to support any-
1390 unique-prefix matching on target names.]
1391 * valops.c (value_struct_elt): Avoid infinite loop on an
1392 erroneous attempt to print the member of function (try p main.p).
1394 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1396 * expread.y (name_no_typename): Avoid reduce/reduce errors
1397 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1398 Since the GDB parser really doesn't use name_no_typename in a
1399 name-only context, the parser can't tell the diff between
1400 names and numbers here. Avoid allowing a name_no_typename
1401 to be a NAME_OR_*INT to resolve the conflict.
1403 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1405 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1407 * valprint.c (val_print_fields): bitfield printing didn't handle
1408 byte order. Indirect through a few more fns to cope.
1410 * values.c (modify_field): also cope with byte order.
1412 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1414 Cleanup for release 3.94.2:
1416 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1417 include files. Roll version to 3.94.2.
1419 * coffread.c (init_stringtab): Read length into unsigned char
1420 array before swapping; don't assume 32-bit longs.
1422 * target.c (target_info): Don't bother with get_sym_file, just use
1423 the symfile global variable.
1424 * symtab.h, symfile.c (get_sym_file): Delete it.
1426 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1427 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1428 (read_type): Replace one more error() with complain().
1430 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1432 * i960-tdep.c: Fix copyright attribution.
1434 * config.gdb: Quote all backquotes in doublequotes. You can
1435 quote me on that. BSD 4.4 shell found this one.
1437 * infptrace.c (throughout): The third argument to ptrace is an
1440 * infrun.c (wait_for_inferior): When program has terminated, we
1441 have to call target_terminal_ours before we pop that target off
1442 the stack (e.g. before a call to target_kill or
1443 target_mourn_inferior). This fixes problem where a program
1444 terminates, then GDB stops for (tty output) and you have to type
1445 "fg" to the shell to resume it. FIXME: This code for what to
1446 do after termination really should be in normal_stop instead.
1448 * gdbcore.h (read_memory_check): Change declaration; it changed
1451 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1452 4.4 prereleases, this avoids a bug in their sgtty compatability
1454 * remote.c: Use terminal.h rather than hand-rolling the same.
1456 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1457 * utils.c (strsave, strstr): Fix arg types.
1458 * valprint.c (val_print): lint
1460 MIPS symbol table support from Per Bothner:
1462 * symfile.c (symtab_fns): Remove initializer table that needs to
1463 be hacked for each new symbol file format supported.
1464 (add_symtab_fns): New function, chains symbol table
1465 handlers into the global list.
1466 (symfile_init): Search this list.
1467 * symfile.h: Add next pointer, declare add_symtab_fns.
1468 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1469 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1471 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1472 symbol *). Thus, we no longer need the hack to trash
1473 pst->filename. Good, since that hack confused code in symfile.c!
1475 (reorder_symtabs, destroy_all_symtabs): Removed static
1476 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1477 Instead, the latter now uses a temporary array (stack-allocated
1478 from an obstack, and then freed).
1480 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1481 haven't been set in the outermost stBlock of a procedure. This was
1482 a problem with f77 binaries on Ultrix 4.?.
1484 (new_symtab, new_symbol, new_type): Continue changing code to use
1485 obstacks more and otherwise conform to dbxread internal style.
1486 Made the free_code of symtabs be free_linetable (as in dbxread)
1487 instead of free_contents. This implies memory leaks when reading
1488 a new symbol table, until the conversion is finished. Did change
1489 (struct symbol) and (struct type) to be allocated on the
1490 symbol_obstack. Blocks and blockvectors are among the things
1493 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1494 tested much, but it solved one problem (reported by Meissner), and
1495 cleans up some other things. The problem happened when an
1496 included file contains actual code (functions) and not just
1497 definitions. The mips coff is a little inconvenient there, since
1498 it may cause a procedure to be mapped to the wrong psymtab.
1500 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1501 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1502 this will need work for the new core paradigm.
1504 Opcode patches from the net:
1506 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1507 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1508 missing altogether - they are added here. From Bruce Bauman.
1509 * mips-opcode.h: The low mask for C0 instructions was too small.
1510 From Garrett Lau. I modified the fix to check the entire 32-bit
1513 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1516 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1518 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1520 * dbxread.c (read_type): Pointer subtraction (value_sub in
1521 valarith.c) sometimes failed because the types of the
1522 pointers being subtracted were not identical.
1523 These differed because dbxread.c was allocating pointer types
1524 using dbx_alloc_type+smash_to_pointer_type instead of
1525 lookup_pointer_type. I failed to find a justification for the
1526 former, so I changed it to use the latter. Similarly, I
1527 replaced smash_to_function_type by lookup_function_type,
1528 and smash_to_reference_type by lookup_reference_type.
1530 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1531 _initialize_mipsread): corresponding changes.
1533 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1535 * source.c (mod_path): Do tilde_expand on each component of the path,
1536 rather than on the (list of) paths as a whole.
1537 (print_source_lines): Set first_line_listed in addition to
1538 current_source_symtab and current_source_line. If the source was
1539 not findable, after a "dir" command to fix the problem,
1540 a "list" would get the wrong lines.
1542 While I was there... (gnu):
1544 * dbxread.c (read_type): Change error to complaint.
1546 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1548 First attempt at detailed understanding of symbol table memory alloc.
1550 * dbxread.c (dbx_symfile_read): Free our string table if we
1551 aren't the mainline. Free the "info" struct since we're done with
1553 (init_psymbol_list): Free any previously allocated psymbol lists.
1554 (): FIXME: Should realloc-down the psymbol lists when done reading
1555 the main symbol file?
1557 * symmisc.c (free_symtab): Free fullname field too.
1559 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1560 (REGISTER_ADDR): Make result type unsigned int.
1562 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1563 define REGEX must also define REGEX1 (its dependency).
1565 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1567 * tconfig/i960: No longer works, points you at vxworks960 or
1570 * xgdb.c, XGDB-README: Remove file. Users can get the much
1572 * Makefile.dist: Remove all trace of xgdb.
1574 * breakpoint.c (breakpoint_1): Pass demangle arg to
1575 print_address_symbolic.
1576 (clear_breakpoints): Remove unused function.
1577 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1578 (breakpoint_re_set): Use catch_errors to do them all anyway.
1580 * gdb-int.texinfo (Host versus Target): Add section on what is
1581 a "host" feature versus what is a "target" feature.
1583 * infcmd.c (path_command, path_info): Handle the PATH variable
1584 (object search path) as conveniently as the source search path.
1585 * environ.c (set_in_environ): Set some vars in GDB's environment,
1586 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1587 * source.c (mod_path): New function, from guts of
1588 directory_command, modifies a path. Used by path_command.
1589 (directory_command): Call it.
1590 * defs.h (strsave): Declare.
1592 * utils.c (sevenbit_strings): Add new printing option.
1593 (printchar): Use it.
1594 (strsave): Provide this handy helper routine.
1595 (set_width_command): Rename set_screen_width_command.
1596 (_initialize_utils): "set screen-width" => "set width";
1597 "set screen-height" => "set height"; add sevenbit-strings.
1599 * infcmd.c (do_registers_info): Print floating point registers
1600 in raw hex as well as float format, regardless of whether it is
1601 a "virtual" convertible register.
1602 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1603 regs as a double, just in case it's being used that way.
1604 * values.c (unpack_long): Comment on array/function coercion.
1605 (unpack_double): Argument is in target byte order now. For
1606 integer arguments, just call unpack_long and float the result.
1607 * m68k-tdep.c: include defs.h for "const" handling.
1608 * remote-nindy.c: Use ieee-float stuff.
1609 (nindy_fetch_registers): Unpack double regs to host double, then
1611 (nindy_store_registers): Pack extendeds to host double, flip
1612 around by misusing unpack_double, send as target double.
1614 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1615 zero, as when stopped at the first instruction of a process.
1617 * blockframe.c: Fix filename in comment (param.h => tm.h).
1618 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1619 * tm-68k.h: Fix typos.
1621 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1623 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1625 * coredep.c (fetch_core_registers): Pass end-address of register
1626 section to register_addr as expected. Don't call supply_register
1627 if we'd just pass it garbage.
1629 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1631 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1633 * target.c (push_target, target_info): Cast enums to int for < or
1636 * stack.c (print_frame_info): Identify source file & line
1637 even if we can't print it.
1639 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1641 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1643 Clean up IEEE floating point support.
1645 * ieee-float.h: New file.
1646 * ieee-float.c: Write real routines to convert between host
1647 doubles and various target IEEE extendeds.
1648 * m68k-xdep.c: Eliminate assembler code for extended floats.
1649 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1650 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1651 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1652 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1653 double_to_ieee_extended.
1654 * i960-tdep.c: Define ext_format_i960.
1655 * m68k-tdep.c: Define ext_format_68881.
1656 * sparc-tdep.c: Define ext_format_sparc, though unused.
1657 * Makefile.dist (HFILES): Add ieee-float.h.
1658 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1661 Obsolete the "coffstrip" program in favor of using BFD's strip.
1663 * nindy-share/coffstrip.c: Remove file.
1664 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1665 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1666 * tconfig/nindy960: Remove reference to coffstrip.o.
1668 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1670 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1672 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1673 * dbxread.c: Remove static symfile_bfd.
1674 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1676 * inftarg.c (child_detach): Pop the child_ops vector if the
1677 detach is successful.
1678 * remote-nindy.c (nindy_create_inferior): Don't push a new
1679 nindy_ops since nindy uses the same one for execution and memory
1681 * core.c (core_ops): Use child_attach and child_create_inferior
1682 rather than default attach and create_inferior functions.
1684 Handle floating point registers in core files.
1686 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1687 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1688 This version untested since BFD doesn't yet support sun3 core
1690 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1691 conventions. Fix comments and style. This version has not
1692 been compiled yet, since we have no HP inhouse.
1693 * core.c (get_core_registers): Look for two sections, ".reg"
1694 and ".reg2", and pass both to fetch_core_registers sequentially.
1696 Revise directory path yet again.
1698 * source.c (forget_cached_source_info): Not static any more.
1699 (init_source_path): New default source path is "$cdir:$cwd".
1700 (dir_command): Handle variable arguments ($cdir, $cwd).
1701 (source_info): Print "Compilation directory" rather than
1702 "Originally compiled in" to remind people of $cdir.
1703 (openp): If the path contains $cwd, use current directory.
1704 (open_source_file): If compilation directory is known, replace
1705 first $cdir in path with the compilation directory.
1706 (print_source_lines): Even if we can't print the lines, set the
1707 current symtab and line for future commands like "info source" or
1708 "breakpoint". Also, error message now contains the file name,
1709 line number, and file access error message.
1710 (_initialize_source): Fix help text to describe changes.
1711 * main.c (cd_command): Forget cached source info when we chdir.
1712 * utils.c (strstr): Add simple implementation.
1714 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1716 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1717 Byte-swap COFF symbol tables if necessary when reading them in.
1718 Use complain() to replace error message in one spot. Needs
1719 corresponding change in bfd/coff-code.h to make some symbol
1720 swapping routines non-static.
1722 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1724 Merge changes from Eirik Fuller, for UTek.

1727 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
1728 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1729 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1730 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
1731 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
1732 declarations of errno.
1734 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1736 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1737 <rpc/rpc.h> and <rpc/types.h>.
1739 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1741 * i960-tdep.c (examine_prologue): Add new argument limit,
1742 which stops the scan at the end of the prologue, or at the PC.
1743 This fixes a problem where it walks down into the code for the
1744 user's statements if that code looks like function prologues.
1745 Mark Fox and I have been bouncing this code back and forth, making
1746 small changes to it. Callers changed to match.
1748 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1750 Cleanup for gdb-3.94 release final:
1752 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1753 the .c files from vx-share and nindy-share, from the various
1754 macros, since they are not found via ALLDEPFILES.
1755 (SFILES): Add tm-i960.h.
1756 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1757 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1759 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1760 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

1764 * am29k-tdep.c: Add contribution line.
1765 (examine_prologue): Cache information about function prologues in
1766 the misc-function-vector to avoid lots of references over the
1767 serial line while examining instructions.
1769 * core.c (core_close): New function made from cleanup_core.
1771 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1772 remote-vx.c, remote.c, target.c, target.h,
1773 Update target_ops vector to add attach, close, and load entries.
1774 Use add_syms_addr_command, not add_file_addr_command, for
1775 add_file. Break out close routine from existing code.
1777 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1778 they are in an obstack.
1779 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1781 (define_symbol): Add symbol type parameter; change callers;
1782 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1783 it to influence the symbol class on the i960.
1784 (define_symbol): Swap LOC_CONST's into target byte order.
1786 * exec.c (exec_close): New function.
1787 (exec_file_command): Call it.
1789 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1790 Fix byte order of frame pointer.
1791 (read_var_value): Result of 0 if var's value can't be found,
1792 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1793 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1794 (locate_var_value): Use read_var_value and use its lazy address
1795 as the location of the var's value. Lint.
1797 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1800 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1801 obsolete Intel versions in favor of vxgdb versions.
1802 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1803 code dealing with byte order of values, which Intel did in host byte
1804 order rather than gdb-4's target byte order.
1805 (i960_frame_chain_valid): Move to nindy-tdep.c.
1806 (examine_prologue, skip_prologue, frame_find_saved_regs,
1807 frame_args_address, leafproc_return, saved_pc_after_call,
1808 pop_frame): Add vxgdb versions from Mark Fox.
1809 (examine_prologue, frame_struct_result_address): Add code
1810 to deal with the saved value of G13 (struct return address
1812 (frame_args_address): Modify Mark's version to prefer the
1813 saved value over the current value in the topmost frame.
1814 Cache result in the frame info to avoid performance hair in
1816 (print_fault): Add gdb960 code for printing faults.
1817 (_initialize_i960): Actually call check_host.
1819 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1820 add stub routines. FIXME, these currently just return zero!
1822 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1823 (attach_command): Call target_attach, not target_open, now.
1825 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1826 (child_attach): Rename from child_open.
1827 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1828 don't confuse it with a zero step_resume_break_address.
1830 * inftarg.c (child_detach): Eliminate inferior_pid test.
1831 (child_files_info): Clean up message a bit.
1832 (child_ops): Use child_attach, not child_open, to attach.
1834 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1835 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1836 findvar.c to here, since it depends on the contents of the
1837 shadow_contents of breakpoints, but keep if #if 0 since it is
1840 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1843 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1844 (ptype_command, display_command): Eliminate have_inferior_p and
1845 have_core_file_p in favor of target_has_stack or
1846 target_has_execution.
1847 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1848 code for actually finding the values of arguments, though we still
1849 keep track of the maximum stack offset for use in printing unnamed
1850 arguments. Handle missing FRAME_ARGS_ADDRESS.
1852 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1853 (struct nindy_regs): Define registers passed to/from nindy.
1854 (nindy_fetch_registers, nindy_store-registers): Translate between
1855 nindy and GDB formats for the registers.
1856 (dcache_init): Statically allocate the cache, since it was being
1857 allocated by a malloc that was never freed anyway.
1858 (nindy_create_inferior): Error, not core dump, if no exec file.
1859 (nindy_before_main_loop): Use target_load, not target_add_file.
1861 * remote-vx.c (net_load): Specify large timeout for load
1862 requests. Allow user to break out with INTERRUPT.
1863 (net_break): Remove useless code, clean up. Change callers.
1864 (parse-args, skip_white_space, find_white_space): Clean up arg
1865 parsing to cope with quoted strings.
1866 (net_wait, net_quit): Never call error, just return status.
1867 (vx_read_register, vx_write_register): Cleanup status checking.
1868 #ifdef the code based on which CPU we are using (960 or 68k),
1869 FIXME, this should be completely general but it isn't yet.
1870 (vx_xfer_memory, vx_resume): Cleanup status checking.
1871 (vx_run_files_info): Improve message.
1872 (vx_load_command): Renamed from vx_add_file_command. Allow load
1874 (net_ptrace): Remove unused routine.
1875 (vx_wait): Adopt code from vxgdb960 to cope with broken
1876 connections to target machine and prompt to disconnect. Remove
1877 debug printouts. Map some EVENT_'s to SIGnals.
1878 (add_symbol_stub, vx_open): Print names of object files we found,
1879 and "ok" if we read their symbols OK. Clarify output in general.
1880 (vx_attach, vx_detach, vx_kill): Add these commands.
1881 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1882 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1883 "info files" output, and create_inferior, since we already have
1886 * stack.c (frame_info): Replace Frame_unknown with 0.
1887 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1888 (return_command): Pop until the PC matches as well as the FP,
1889 so it works even if the FP is shared with another function,
1890 as in "frameless" or "leaf" procedures.
1892 * symfile.c (load_command): renamed from add_file_target_command.
1893 (add_syms_addr_command): renamed from add_file_addr_command.
1894 (add_syms_command): Stub to call target_add_syms.
1895 (_initialize_symfile): Change command names and descriptions,
1896 add-file => add-syms, and load from alias to its own command.
1898 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1899 maybe_kill_then_create_inferior): Default for attempts to start
1900 a process, if one is already running, is to ask about killing
1901 it and retry if yes.
1902 (upstack_create_inferior): #if-0 it, strata obsolete it.
1903 (push_target, unpush_target, pop_target): to_close() a target
1904 before unstacking it.
1905 (target_info): Renamed from target_files_info.
1906 (_initialize_targets): Rename "i files" as "i target", accessible
1909 * target.h: Improve comments about the target_ vectored routines.
1911 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
1912 Convert commenting style to standard GNU style.
1913 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
1914 (SKIP_PROLOGUE): No longer a no-op.
1915 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1916 (*_REGNUM): Sort register numbers.
1917 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1918 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1919 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1920 are now 10 byte extendeds, not 8 byte doubles.
1921 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1922 for nindy versus vxworks targets. FIXME, this should possibly go
1923 in the target vector.
1924 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1925 frame_saved_regs and arg pointer with each frame.
1926 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1927 (FRAME_ARGS_ADDRESS): Use cached result.
1928 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1929 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1930 (PRINT_RAMDON_SIGNAL): Call print_fault.
1931 (POP_FRAME): Now works.
1933 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1934 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1935 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1936 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1939 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1940 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1942 * valarith.c (value_subscripted_rvalue): Avoid handling
1943 floats and doubles specially; it gave alignment errors. Lint.
1945 * valops.c (value_of_variable, value_of_this): Error if unknown
1948 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1949 to avoid alignment problems.
1950 (value_print): Handle unknown value address.
1951 (cplus_val_print): Two args are ignored; remove them. Change caller.
1952 (val_print): Use unpack_long rather than pointer-deref.
1955 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1956 to avoid alignment problems.
1957 (value_being_returned): Error if return value unknown.
1958 (set_return_value): Add bogosity warning, FIXME. *
1960 * TODO: A woman's work is never done.
1962 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1963 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1964 Add ieee-float.o to OBS.
1965 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1966 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1967 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1969 Changes to generalize the VxWorks RPC protocol slightly, to handle
1970 i960 as well as 68000.
1972 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1973 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1974 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1975 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1976 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1977 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1978 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1979 so they will move in target byte order rather than network
1980 byte order (happens to be the same).
1982 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1984 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1986 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1989 Add contribution lines to various files, showing where they
1992 * breakpoint.c (break_insn, check_break_insn_size,
1993 read_memory_nobpt): Remove to mem-break.c.
1995 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1998 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1999 entry has bad register number. This change is not
2000 tested in this release, FIXME.
2002 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
2005 * value.h: Force value's contents field to be aligned to hold
2006 at least a double or a long long (if supported). This avoids
2007 doing bcopy's in and out of the contents field.
2009 (step_1): Avoid coredump under obscure circumstances when we
2012 * symtab.h (misc_info): Add field to misc function vector for
2013 any kind of cached information the target code desires. AMD
2014 29000 uses this to avoid repeating examine_function_prologue's.
2016 * coffread.c: Lint. Remove static symfile, read_section_header.
2017 core.c (have_core_file_p): Lint: remove.
2018 expprint.c (print_subexp): Lint.
2019 infptrace.c, valops.c, valprint.c: lint.
2021 Roll in changes from vxgdb-5.0.1:
2023 * symtab.h: Comment byte order of each address class. Add
2024 LOC_LOCAL_ARG for frame-relative args (960).
2025 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
2026 symtab.c, symmisc.c: ditto.
2028 * infrun.c (init_wait_for_inferior): Clear stop_signal.
2030 * remote.c (remote_resume): Error if resume with a signal.
2032 * symfile.c (prim_record_misc_function): Clear misc_info.
2033 (fill_in_vptr_fieldno): Check stub type of arg.
2035 * valops.c (value_cast): Avoid looking up names of types whose
2036 name we don't know, to prevent coredump. Sun CC produces typedef
2037 rtx and the name of *rtx is zero...
2039 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2041 Roll in changes from final AMD 29000 port (Tiemann).
2043 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
2044 for ../include/a.out.encap.h. This might not work now that BFD
2045 is separately compiled. Instead, BFD support for encap will have
2046 to translate machine type 29k into the right COFF_MAGIC.
2048 * infcmd.c: Remove references to inferior_pid that aren't used
2049 in actual ptrace calls; use target_has_execution, etc.
2050 (have_inferior_p): Remove function.
2051 (program_info): Print target info rather than "process number";
2052 avoid gratuitous messages unless from_tty.
2053 (run_stack_dummy, finish_command): Set proceed_to_finish.
2054 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
2055 main.c: Lint. Lose have_inferior_p().
2056 inferior.h (have_inferior_p): Remove, lint.
2057 (proceed_to_finish): Add flag to ask that all regs be saved
2058 by normal_stop, for the few commands that need it, speeding up
2059 serial I/O. Add comments to stop_registers.
2061 * remote-eb.c: Remove newline from breakpoint message we grep
2062 for. Never time out when running the user program.
2066 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2068 Roll in changes from vxgdb-5.0.1:
2070 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
2071 symbol in its raw form, we are processing an unlinked ".o" file.
2072 See if the target environment has assigned it an address, using
2073 target_lookup_symbol (VxWorks does), and enter it into the symtab
2076 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
2077 68k versions for a simpler version that assumes zero FP at bottom.
2078 Fixes bug of truncated stack reports.
2080 * target.h (target_lookup_symbol): Define this routine's args
2081 and result, finally.
2083 * target.c (nosymbol): Default routine for target_lookup_symbol.
2084 (target_default): Default lookup_symbol and call_function too.
2085 (files_info): Only print has_all_memory warning if a non-dummy
2088 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
2089 vx_convert_from_virtual): If target does not have floating point,
2090 zero register "values", and avoid doing cross-net conversions.
2091 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
2092 (vx_open): Rearrange code that attaches to target and reads
2093 symbols for all loaded modules, to work if some of the modules
2094 are not accessible. Add symbol_stub() and add_symbol_stub()
2095 as callbacks from catch_errors(). Allow connect attempt to be
2096 interrupted painlessly with ^C (FIXME, there are still some bugs
2097 if the interrupt happens during symbol reading.). Print
2098 final message with puts_filtered, since symbol messages are
2103 * main.c (catch_errors): Only print errstring if non-null.
2104 (command_loop): Avoid an ioctl per command to test ISATTY.
2106 * remote-vx.c (net_load): make static; avoid sophomoric msg.
2107 (vx_xfer_memory): Return correct result!
2108 (vx_files_info): Indicate whether target has float or not.
2109 (vx_lookup_symbol): Complain, not error, if target gone.
2110 (vx_open): Print "Connected" msg before disabling immediate-quit.
2111 [FIXME: lookup_symbol and vx_open changes need testing.]
2113 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
2114 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
2115 contributor lines and update copyrights to 1991.
2117 Changes from an attempted H-PUX host port:
2119 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
2120 defines PT_ATTACH and PT_DETACH but not PT_KILL.
2121 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
2122 * remote-vx.c: include <sys/time.h> for HPUX.
2123 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
2124 "core_file_command" routine to BFD regime. May not work yet.
2126 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
2128 * xgdb.c: Replace X10 version with some VJ version.
2129 (FIXME: Its copyright assignment is not on record.)
2130 * xgdb.c: Update include files to X11R4 (Xaw crud).
2131 (xgdb_display_source, create_text_widget): fix call to
2132 get_filename_and_charpos. Rewack source window stuff for X11R4
2133 (gleaned from include files, and "nm's" of binary libraries, since
2134 I had no doc available).
2135 (append_selection, append_selection_word): Disable with FIXME
2136 since R4 changed interface here.
2137 (create_buttons): Add back the old set of buttons.
2138 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
2140 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
2141 Roll VERSION to 3.94 (not yet final though).
2143 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2145 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
2146 obstack_int_grow, obstack_int_grow_fast): Eliminate
2147 cast on left of assignment, which gives MIPS cc fits and is
2150 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
2151 F_ALIAS. Use printf, not fprintf, when not passing a file
2153 (compare_opcodes): Check that identical instructions have
2154 identical opcodes, complain otherwise.
2156 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
2157 was reported by Roland McGrath.
2158 (unimp): Only match if exactly zero instruction. (Roland)
2159 (branches and traps): Generate all variations of these
2160 instructions with macros, based on a single call that defines
2161 each condition name and its binary representation.
2162 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
2164 * valprint.c (val_print_fields): Take, and use, format parameter.
2165 This means that "p/x struct" again prints the elements in the
2166 desired format. Changed callers.
2168 * stack.c (frame_info): Use filtered output, and indicate wrap
2169 points. Remove kludgy formatting designed to avoid line wrap.
2171 * utils.c (wrap_here): If the line is already full (because
2172 we had printed a long indent or long wrapped string), do an
2173 immediate newline-and-indent.
2175 * m68k-pinsn.c (print_insn_arg): Bugfix from
2176 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
2177 instruction is incorrectly disassembled as bkpt #8.
2179 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
2180 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
2181 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
2182 and then will dump core (sometimes). I traced it back to an
2183 uninitialized symfile_name in psymtab_to_symtab.
2184 (const_vol_complaint): Add quotes to message.
2185 (define_symbol): Only believe line number if gcc_compiled.
2186 Avoid allocating symbol if we will not return it.
2188 Add target strata support so that newly established targets go
2189 into their right place in the target stack (e.g. a new exec file
2190 doesn't wipe out the ability to access the running process).
2192 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2193 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2194 and initialize it properly in all the targets.
2196 * target.h: Document strata. Change return type of push_target.
2198 * target.c (nomemory): new function for dummy memory access.
2199 (tcomplain): Rename complain, now also used in symfile.c.
2200 (push_target): Push targets within strata. New return value shows
2201 whether new target is on top of stack or not. Always keep dummy
2203 (target_files_info): Ignore dummy target.
2205 * core.c (core_open): Warn user, and skip accessing file, if the
2206 core target is not the topmost target in the stack.
2207 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2210 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2211 target_ops, it doesn't belong there since we have no regs there.
2212 Change name of target from machine => memory to clarify.
2214 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2216 * Freeze version 3.93 for release.
2218 * Makefile.dist: Handle vx-share and nindy-share subdirs
2219 properly when building gdb.tar.Z.
2221 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2222 printed in various places, so I could change just one copy.
2224 * dbxread.c, coffread.c: Change references to bfd->iostream
2225 to cast to FILE *, now that BFD avoids needing types defined
2226 in other header files.
2228 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2230 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2231 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2232 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2233 (actually gcc -Wall).
2235 * dbxread.c: Remove first_global_sym, last_global_sym, since
2236 they are never referenced.
2238 * defs.h (baud_rate): Declare.
2239 main.c: Define it, and add the -b option to set it.
2241 * gdb-int.texinfo: Add text on how to define a new host or target
2242 architecture, prompted by Per Bothner's questions about MIPS
2245 * gdb.texinfo: Document "complaints". Change doc of -q since
2246 gdb no longer prints the copyright and blurb if you specify a file
2247 name to be debugged (just like Emacs). Add doc for Nindy-specific
2248 command line flags for specifying target serial port and such.
2249 Update copyright to 1991.
2251 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2252 has taken over for us the job of ripping up executable files. The
2253 crud caused Per Bothner's port to not compile.
2255 * infrun.c (normal_stop): Avoid printing "Program exited
2256 normally" if we are in batch mode. This allows a GDB which
2257 executes a program on a target system, to behave like a Unix
2258 command (input from stdin, output to stdout, no extraneous
2261 * main.c (main): Allow additional machine-dependent command line
2262 options to be specified with the ADDITIONAL_OPTIONS,
2263 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2264 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2265 processing to occur just before the main loop with
2266 BEFORE_MAIN_LOOP_HOOK.
2267 (main): If a "core file" argument is specified, and it is not a
2268 core file, try it as a process ID to attach.
2269 (symbol_completion_function): Attempt to cope with
2270 "show screen-" TAB, not very successfully. This needs more work,
2272 (batch_file): New function, returns whether we are reading
2273 commands from an interactive tty on stdin, or from somewhere else.
2274 Called by normal_stop since it doesn't get from_tty passed down
2275 to it like many commands do.
2277 * remote-nindy.c: Handle command line options for nindy
2279 (nindy_before_main_loop): Prompt user for tty name if they
2280 don't specify it before getting to the interactive command loop.
2282 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2283 and -r command line options. Also add hook before main loop
2284 to make it easy to specify a tty.
2286 * TODO: More things to do, one done.
2288 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2290 * dbxread.c: Make complaint() calls pass pointer, not struct.
2291 Add complaints about badly formatted C++ type information
2292 (const/volatile indicator, and parse errors resulting in
2293 error_type). Fix C++ virtual member fn comment.
2294 (read_struct_type): Avoid bumping pointer if we got a parse
2295 error; this prevents our walking beyond the end of a string.
2296 Terminate loop on null char as well as semicolon.
2297 (process_one_symbol): Fix the LBRAC fix so that it uses the
2298 last previous SLINE, FUN, or SO record's PC address. C++ debug
2299 symbols did not have SLINE records in a useful order compared
2300 to the LBRAC records.
2301 (define_symbol): Handle "catch" records.
2303 * symtab.c (check_stub_type): Added new complain
2304 `stub_noname_complain' and added a consistency check to
2305 keep the debugger from crashing when finishing from an
2306 exception frame. A real fix will be needed later.
2308 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2310 * infcmd.c (attach_command): Make global.
2312 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2313 but make them easy to comment out. Perhaps later they should
2314 be enabled by what CPU you configure for? FIXME.
2315 (VERSION): Roll to 3.93.
2316 (pinsn.o): Remove rule for obsolete file.
2317 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2319 Run down a problem that manifested by printing the wrong function
2320 name in stack traces of read_ofile_symtab. Turned out that the
2321 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2322 the LBRAC symbol with an address in the *data* segment, which
2323 blew our binary search through the blocks.
2325 * dbxread.c: Use the complain() facility consistently to bitch
2326 about problems in the symbol file we are reading.
2327 (finish_block): Add code to check the nesting of the blocks;
2328 complain and Procrust them to fit if wrong.
2329 (make_blockvector): Check the order of the blocks, complain
2330 [but don't cope] if wrong.
2331 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2332 symbols to be sure their PC value is greater than the last SLINE
2333 (line number) symbol we've seen, complaining and adopting the
2334 SLINE PC value if wrong.
2336 * symfile.h (struct complaint, complaint_root, complain,
2337 clear_complaints): Add.
2338 * symfile.c (complain, complaint_root, clear_complaints): Add
2339 facility to deal with non-fatal complaints and to regularize their
2341 (symbol_file_add): Clear complaint counters to allow new complaints.
2342 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2344 * dbxread.c (dbx_symfile_read): Remember the address and size
2345 of the string table for the main symbol file, so we won't read it
2347 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2348 to avoid reading the string table yet again. Lint.
2349 (throughout): Improve filtered output, including word wrap.
2350 (read_range_type): Improve Bothner's fix to handle other types too.
2352 * utils.c: Improve line wrap implementation. Handle unlimited
2353 width by making chars_per_line unsigned.
2354 (puts_filtered): New, easy, function.
2356 * defs.h (puts_filtered): add.
2358 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2359 call the identical sort_symtab_syms() in symfile.c instead.
2361 * expread.y: Suggest the `file' command rather than `symbol-file'.
2363 * command.h (enum var_types): Add zinteger for seroable
2365 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2366 nested if's into a switch.
2368 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2369 we did not stop because of a breakpoint (it must have been for
2370 some other reason, like a "stepi"), so don't print anything.
2372 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2373 doesn't include <sys/types.h>, old SunOS's require it for
2376 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2378 A test port of gdb-3.92.6 to the Sony NEWS.
2381 Don't normally link in remote- or vx stuff.
2382 Some of it doesn't compile, and it wastes space for 99% of the users.
2383 Remove reference to no-longer-used HAVE_VPRINTF.
2384 Fixed BFD_DEP typo to BFD_DIR.
2386 Fix cast in arg to bfd_h_getlong.
2387 Make char *prefix be const.
2388 Fix how certain range types are mapped into builtin unsigned int types.
2390 Remove 2 #includes. They cause errors (on Sony, at least),
2391 and aren't needed (they wern't in earlier versions).
2393 print_address_symbolic should never demangle labels
2394 (since it prints *assembler-level* labels).
2396 [This was superseded by the change to printcmd below.]
2399 Add some "volatile" return types to avoid warnings.
2400 If MISSING_VPRINTF add vprintf function and not just macro
2401 (since vprintf is used in printcmd.c).
2403 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2404 (The latter isn't grokked by some PCC-based compilers.)
2406 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2408 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2409 * nindy-share/coffstrip.c
2410 Added some forward declarations (otherwise, gcc complains
2411 about implicit extern redefined as static).
2413 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2415 Changes inspired by Per Bothner:
2416 * printcmd.c (print_address_symbolic): Take additional parameter
2417 specifying whether to demangle.
2418 (print_address): Pass in asm_demangle to control demangling.
2419 (print_address_demangle): New fn, takes explicit arg to control
2421 * utils.c: Add new vars demangle and asm_demangle, and let them
2423 (fputs_demangled): If !demangle, just print the argument.
2424 (fprint_symbol): If !demangle, just print raw symbol.
2425 * valprint.c (val_print): Call print_address_demangle rather than
2426 print_address, to cause demangling to depend on the global
2427 rather than assembler-level demangling setting.
2428 * WHATS.NEW, gdb.texinfo: Document.
2430 * main.c (show_command): Show all settings if no arg.
2431 (initialize_main): Make "info set" the same as naked "show".
2432 * command.c (cmd_show_list): Handle prefix commands in the
2433 list, and print the name of the setting as well as its English
2434 description and value.
2436 Allow gdb functions to specify where a line should wrap if it
2437 exceeds the size of a terminal line. Use it to make the output
2439 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2440 of the right size when screen width changes.
2441 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2442 (wrap_here): New fn, indicates a point in the output where we
2443 should wrap the line rather than just letting it overflow at a
2445 (fputs_filtered): Implement wrapping.
2446 (n_spaces): New fn, returns a pointer to N spaces.
2447 (print_spaces_filtered): Use n_spaces.
2448 * defs.h (n_spaces): Declare.
2449 * stack.c (print_frame_info): Wrap with 4-space indent after
2450 fn name and before filename and line number.
2451 * printcmd.c (print_frame_args): Wrap with 4-space indent
2452 before each argument name is printed.
2453 * valprint.c (value_print): Wrap with no indentation before
2455 (val_print_fields): Wrap with indentation relative to nesting
2456 level before each field name.
2457 (val_print): Wrap with nesting indentation before array elements.
2458 * command.c (do_setshow_command): Avoid extra newlines,
2459 wrap with 4-space indent around values printed, end with period.
2460 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2462 * breakpoint.c (breakpoint_1): Implement addressprint for
2463 "info breakpoints" display. Change file name and line number
2464 format to " at file:nnn" rather than " (file line nnn)".
2465 * gdb.texinfo: Document.
2468 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2470 Frozen for gdb-3.92.6 release.
2472 README, WHATS.NEW: Update for 3.92.6 release.
2474 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2475 coffread.o from configs since it is now built by default.
2476 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2477 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2478 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2479 from configs since it is now built by default.
2481 Makefile.dist: Update for release 3.92.6. Handle files that
2482 have been moved to ../include, ../getopt, or ../bfd. Add
2483 saber.suppress and tests directory. Add config.status to
2484 the release (it will say "none").
2486 coredep.c: Minor formatting fixes.
2488 These changes were made in early December but only checked in now:
2489 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2490 nindy-share/nindy.c: lint
2491 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2492 register values coming back from the target; we store values
2493 in target byte order everywhere.
2495 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2497 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2499 * valprint.c (cplus_val_print, val_print_fields): New functions,
2500 which print C++ objects. They conspire to avoid printing a
2501 virtual base class more than once, following all the twists and
2502 turns of C++ virtual base rules.
2503 (val_print): Call the above rather than do it by hand.
2505 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2506 symbol file, not for added files like shared libs. This really
2507 needs to be generalized to a timestamp per file.
2509 * core.c (cleanup_core): Avoid coredump if no core file.
2511 * config.gdb: Accept -host or -target in place of +host or
2514 * coffread.c (find_linenos): Avoid desupported BFD interface
2515 to line numbers. We still read them manually rather than using
2516 BFD's "generic" features.
2518 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2520 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2522 * Makefile.dist: Eliminate use of $< in explicit targets.
2524 * readline/Makefile: Use $< rather than $*.c, which does not
2525 include the VPATH in GNU Make.
2527 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2528 copies of tconfig/i960, added for global configuration
2529 compatability. All i960 versions can read both coff and b.out.
2531 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2532 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2535 * TODO: Think of more things to do.
2537 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2539 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2540 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2541 64-bit float conversion.
2543 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2544 equivalent to sun?os4 so global config works.
2546 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2548 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2550 * main.c: Only declare linesize once; declare pagesize not at
2551 all, since it is never used.
2552 (main): Clear newly allocated line before it is used.
2554 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2556 Further stabilization for the Intel 960.
2558 * Makefile.dist: Parameterize the location of the "include"
2559 and "bfd" directories, as well as "getopt". Add symfile.c.
2560 Link in both dbxread and coffread. Fix up "make depend" to
2561 rewack the locations of include, bfd, and getopt in its output.
2563 * README: Document moving include files, improve some of
2566 * coffread.c: Move common code out to symfile.c. Change
2567 symbol_file_command style interface to use new *_symfile_init
2568 and *_symfile_read interface under BFD. Use BFD internal
2569 info to locate line table, symbols, etc.
2571 * core.c (core_fetch_registers): Rename to get_core_registers
2572 to avoid confusion with fetch_core_registers.
2573 (register_addr): Move to coredep.c, which is already machine
2574 dependent. This leaves core.c pretty clean of dependencies.
2576 * coredep.c (register_addr): Accept this routine from core.c.
2578 * dbxread.c: Move common code (with coffread.c, etc) into new
2579 symfile.c. Each psymtab now contains a pointer to the
2580 format-dependent function that knows how to read it in. Make
2582 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2583 (process_one_symbol): Add code to complain about a "compiler bug
2584 we muzzle here", if we actually see it.
2586 * eval.c (evaluate_subexp): Insert missing "break" statements
2587 in code that determines whether a variable is an lvalue in
2588 memory, register, or whatever. I detected this via a compiler
2589 bug in which it *almost* mashed out the whole switch statement.
2591 * gdb-int.texinfo: Add minor sections on configuring gdb for
2592 release, and about the README file.
2594 * infcmd.c (registers_info): Fix formatting somewhat. Still
2595 not as pretty as before, but it handles byte swapping.
2597 * remote-nindy.c: If data cache routines are interrupted while
2598 waiting for the remote end, be sure that any uninitialized cache
2599 blocks are on the free list, not on the valid list!
2601 * symfile.h: Flesh out this header file with all the various
2602 routines and variables that have been merged in from dbxread.c
2603 coffread.c, and symtab.c to symfile.c.
2605 * symfile.c: New file, containing code common to dbxread.c,
2606 coffread.c, and some code from symtab.c. All generic code for
2607 reading symbol files should be in here now.
2608 (unrecord_misc_function): Remove unused function.
2610 * symtab.h: Remove file-reading things to symfile.h.
2612 * symtab.c: Remove file-reading things to symfile.c.
2614 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2615 to decode i960 fault types.
2617 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2618 target.c: Change type of the "resume" function from int to void,
2619 since its result was never used.
2621 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2623 * main.c: Replace "stupid" with "caution"; you now "set caution
2626 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2628 * infcmd.c (do_registers_info): Call val_print to deal with the
2629 byte order of the registers being printed. FIXME, this makes
2630 the formatting of the output uglier.
2632 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2633 defined, call it for signals the debugger doesn't itself use.
2634 The i960 uses this for more detailed fault information.
2636 * remote.c (remote_open): If arg is null, print help rather than
2639 * sparc-xdep.c (register_valid): Avoid declaring size, since
2640 various modules will think of various sizes depending on the
2641 architecture of their tm-file. FIXME, we need protection against
2642 actually entering one of those modules, which would clobber
2643 storage if not for the target architecture compiled into gdb.
2645 * stack.c (up_command, down_command): Always print the frame
2647 (up_silently_command, down_silently_command): New commands
2650 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2652 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2653 more parameters than it used to.
2655 * findvar.c (registers): Increase slop to 256 bytes, which should
2656 protect us against even most RISC machines with large register
2658 (locate_var_value): Move declaration inside related ifdef.
2660 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2661 throughout, to avoid throwing away buffered input from the board.
2662 (nindy_wait): Supply_register takes addr_of_value, not value.
2663 (i960_print_fault): Renamed from i80960_fault.
2664 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2665 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2667 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2668 we can set the PC in the call to proceed(). Unpush nindy_ops
2669 before pushing it on top, to avoid message to user. Eliminate
2670 commentary from Unix machines that just misleads here.
2671 (reset_command): Fix error message to suggest target command.
2673 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2675 Release 3.92.5 as frozen.
2677 Stabilize the merged release...with help from lint, Saber C,
2680 Everywhere: Add include files needed to declare return types
2681 of functions called.
2683 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2685 * breakpoint.h: Add undeclared breakpoint functions, and some
2686 functions for display handling since I couldn't think of a better
2689 * breakpoint.c (insert_breakpoints): Make code for disabling
2690 shared library bkpts more likely to work. It's used when we
2691 rerun a program and stop before the shared library has been
2693 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2694 cast from pointer, so it squeezes through catch_errors.
2695 (bpstat_stop_status): Fix logic broken some time ago. We now
2696 always create a bpstat if the stop address matches a breakpoint,
2697 even if we don't stop there -- just like the old code used to do
2698 before I got my fingers into it (sigh).
2699 (breakpoint_1): Print "ignore count" after "stop only if"
2700 condition, since that's how it actually works.
2701 (mention): Handle watchpoints as well as breakpoints.
2702 (watch_command): use set_raw_breakpoint and mention to do most
2703 of the work (and initialize all the fields!). Only pass one
2704 arg to parse_c_expression, since that's all it takes.
2706 * command.c (not_just_help_class_command): Rename arg to args
2707 since we ignore "unused argument" warnings on vars named "args".
2708 inflow.c (child_terminal_info): ditto.
2709 infptrace.c (kill_inferior): ditto
2710 main.c (catch_errors, version_info, quit_command, pwd_command,
2711 source_command, dump_me_command, editing_info,
2712 set_history_size_command, set_history, show_history,
2714 stack.c (locals_info): ditto
2715 target.c (target_files_info): ditto
2716 valprint.c (set_input_radix, set_output_radix): ditto
2718 * core.c: Remove old variables for handling core and exec file
2719 sections (data_start, data_end, stack_start, stack_end,
2720 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2721 text_end, exec_data_start, exec_data_end, text_offset,
2722 exec_data_offset, data_offset, stack_offset). They're
2723 superseded the more general build_section_table and
2725 (get_exec_file): Mention the `file' command.
2726 (read_memory_check): Rename to memory_error, and only call it
2727 in the case of an actual error.
2728 (read_memory, write_memory): call memory_error.
2729 (core_fetch_registers): Register section name is ".reg".
2731 coredep.c: Remove a bunch of crud now that all this file does
2732 is pull the registers out of a core file.
2733 (fetch_core_registers): Rewrite to actually work, I hope.
2735 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2736 Replace index() with strchr(). Remove all the pre-BFD macro
2737 definitions for accessing the symbol file.
2738 (struct dbx_symfile_info): Encapsulate the information that
2739 dbx_symfile_init needs to pass to dbx_symfile_read in this
2742 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2743 dbx_symfile_discard): Rearrange symbol file reading to divide
2744 the format-specific part from the format-independent part,
2745 leaving the format-independent part such as file name expansion
2746 and opening in symtab.c. This replaces
2747 partial_symbol_file_open and partial_symbol_file_read.
2748 Symbol_file_read, add_file, add_file_target_command,
2749 add_file_addr_command move to symtab.c. Pass an explicit
2750 "mainline" flag for when reading the main symbol table, rather
2751 than relying on the offset address to be zero or nonzero.
2753 (dbx_symfile_read): Don't allow void *'s to be printed as
2755 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2756 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2757 macro" debug version really work.
2758 (read_dbx_symtab): Remove unref'd parameter inclink.
2759 Avoid swapping N_SLINE symbols, for speed.
2760 Merge N_TEXT!N_EXT case with the other external symbol
2761 definitions' case. Add comments.
2762 (start_psymtab): Allocate the symfile name in the psymtab on
2763 the psymbol_obstack, rather than using the caller's storage.
2764 (end_psymtab): Only allocate a dependencies list if there are
2766 (psymtab_to_symtab_2): Use BFD when reopening file to read
2767 its symbols for real.
2768 (read_struct_type): Add FIXME comments where it needs work
2770 (read_huge_number): Add FIXME about overflows.
2771 (read_range_type): Add FIXME about comparing a long to 1<<32.
2773 * coffread.c: Minor changes to move things closer to the new
2774 regime with symtab.c and dbxread.c Major work is still needed
2777 * exec.c (exec_file_command): Remove old variables (see core.c
2779 (xfer_memory): If memory transfer is right at the end of a
2780 section, don't lose.
2782 * findvar.c (get_saved_register): If value is in a real
2783 register, LVAL is lval_register, not lval_memory.
2785 frame.h: Declare print_sel_frame and record_selected_frame.
2787 gdb-int.texinfo: New file, for GDB internals documentation.
2788 Very simple, unformatted doc of cleanups is there for now.
2790 gdbcore.h: Remove obsolete variables that described a.out
2791 section addresses and offsets. (See core.c above.)
2792 Declare fetch_core_registers and registers_fetched.
2794 getopt.c: Declare char *alloca(); even on SPARC.
2796 infcmd.c (run_command): Call target_kill rather than
2798 (step_command, next_command, stepi_command, nexti_command):
2799 Declare from_tty parameter even though we don't use it.
2800 (run_stack_dummy): argument BUFFER is a char array, not
2801 a pointer to REGISTER_TYPE.
2802 (finish_command): using_struct_return needed a value *,
2803 not a struct symbol *.
2805 * infptrace.c (child_xfer_memory): To avoid dependency on
2806 where sections are in memory, try PT_WRITE_D and if that fails,
2807 try PT_WRITE_I. Most Unixes don't care which you use.
2809 * infrun.c (step_resume_break_shadow): Change to array to
2810 match other breakpoint shadow storage.
2811 (clear_proceed_status): Pass address of bpstat to
2812 bpstat_clear, not the bpstat itself.
2813 (child_create_inferior): FIXME comment about if the child
2815 (start_inferior): Remove old function.
2816 (child_open): Use target_kill rather than kill_inferior.
2817 (wait_for_inferior): Ditto.
2818 (insert_step_breakpoint, remote_step_breakpoint): Use
2819 new step_resume_break_shadow.
2821 * inftarg.c (child_wait): If all child processes die,
2822 pretend that the one being waited for exited with signal 42.
2824 * main.c (command_line_input): When scanning for comments,
2825 don't coredump on unclosed quotes.
2826 (quit_command): Use target_kill rther than kill_inferior.
2827 (_initialize_main): Rename class_user from "user" to
2830 * printcmd.c (print_command_1): Initialize "fmt" if no format
2831 is specified by the user.
2832 (print_frame_args): Only add to args_printed if we are
2833 actually fetching args from the stack (avoiding undefined
2835 (_initialize_printcmd): Remove bogus \{ from string.
2837 * remote-eb.c (eb_open): Avoid coredump on no argument.
2839 * remote-nindy.c: Bring out of Intel environment into new
2840 target environment. Remove all conditional compilation on
2841 I80960. Massive hacking throughout.
2842 (nindy_xfer_inferior_memory): New routine stolen from
2844 (nindy_create_inferior): New routine pieced together, probably
2845 not quite working yet.
2846 (nindy_ops): New target_ops struct for nindy.
2848 * remote-vx.c: Use write_memory rather than target_write_memory
2849 to get error checking.
2850 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2852 (vx_create_inferior): Use target_terminal_ours...
2854 * signame.c (_initialize_signame): Always initialize, since
2855 we need the table for things other than psignal.
2857 * solib.c (solib_add): Use symbol_file_add, not add_file.
2858 (solib_address): Return boolean result rather than struct
2859 pointer which nobody else knows the type of.
2861 * sparc-tdep.c, valops.c: Use write_memory rather than
2862 target_write_memory, to get error checking.
2864 * stack.c (locals_info, catch_info, args_info,
2865 get_selected_block, frame_command, up_command): Use
2866 target_has_stack, rather than have_inferior_p or
2869 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2871 * symfile.h: New file, defining the interface between the
2872 generic and object-file-specific symbol reading code.
2874 * symtab.c: Move generic symbol-reading interface to symtab.c,
2875 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2876 table to map BFD targets to symbol-reading modules in GDB.
2877 Change index to strchr.
2878 (lookup_struct_elt_type): Use error() rather than hand-made
2879 simulations thereof.
2880 (lookup_partial_symbol): Speedup slightly when length == 0.
2881 (symbol_file_add): New function.
2882 (symbol_file_command): Call it.
2883 (symfile_open, symfile_init): New function.
2884 (add_file_target_command, add_file_addr_command): moved from
2887 * target.c (target_command): use target_kill.
2889 * target.h (target_files_info): Don't declare, never called
2892 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2893 files to determine stack end address.
2895 * valarith.c (value_x_binop, value_x_unop): Change error message
2896 to be more useful. Pass proper argument to value_struct_elt.
2898 * valops.c (value_assign): FIXME comment that long long
2899 bitfields will break here.
2901 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2902 Update `make saber_gdb' to work better.
2904 * TODO: A woman's work is never done.
2906 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2907 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2908 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2909 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2910 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2911 valops.c, valprint.c, exec.c: Lint.
2914 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2916 Continuing Intel 960 port merge of GDB.
2918 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2919 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2920 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2921 Wack over "make depend" so it handles files in subdirectories
2922 vx-share, nindy-share, bfd, and in the current directory.
2924 * blockframe.c (get_prev_frame_info): Remove fatal error
2925 if stack not defined.
2927 * core.c (core_open, core_detach): New functions that handle
2928 the old "core-file" command as "target core" and "detach" instead.
2929 (core_file_command): Call them.
2930 (core_xfer_memory): Use common routine xfer_memory.
2932 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2933 dbxread now uses bfd for everything but symbol reading itself.
2934 BFD internals are used to drag out the relevant file offsets.
2935 (partial_symbol_file_open): Change args all around for BFD.
2937 * symtab.c: Rename "value" to "val" everywhere, so we can
2939 (symbol_file_command): New command, moved from dbxread.c
2940 and coffread.c. It uses BFD to read the file, then vectors
2941 based on its type, to dbx or coff symbol readers.
2942 * symtab.h: Extern a few vars for symbol_file_command.
2944 * target.h: Breakpoint takes a char * save area, not a char **.
2946 * valprint.c (val_print): When unpacking bitfields, offset
2947 the address in gdb of the value, if it is declared with a shorter
2948 type. Remove the last "runtime kludge test" of host byte order.
2950 * utils.c: Remove old my_bfd_read routine.
2952 * stack.c (frame_info): Use target_has_stack. Print program counter
2953 register's actual name rather than "pc", since it's called the
2954 "ip" (instruction pointer) on the i960 (sigh).
2956 * target.c (target_command): Add command for selecting a target
2957 type and calling its open routine. This is used for initiating
2958 communication with a particular target, in a generic way.
2960 * tm-i960.h: Update for modern gdb. Remove semicolons from
2961 various macros. Handle reading struct return convention, and
2962 error-out attempts to return structs with the "return" command.
2963 Be sure gdb doesn't think we know how to call functions in the
2966 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2967 to i960_xxx in lower case.
2968 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2969 not being defined yet.
2971 * remote.c (remote_open): Call start_remote to initialize
2972 wait_for_inferior during open.
2973 (remote_xfer_inferior_memory): Return length written rather
2976 * remote-vx.c (target_command -> vx_open): Use new generic
2978 * remote-eb.c, inftarg.c, exec.c: ditto.
2980 * infrun.c: Fix comments.
2981 (attach_program -> child_open): Use new generic target command.
2982 (wait_for_inferior): Clear saved register values before target_wait,
2983 so target_wait can set some of them if convenient.
2985 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2986 Return success indicator, not void.
2987 (child_xfer_memory): Avoid fetching initial word if we'll
2988 overwrite it anyway.
2990 * infcmd.c (attach_command): Use new generic target open routine.
2991 (_initialize_infcmd): Update doc on attach and detach commands.
2992 (do_registers_info): Merge in a byte-order problem as a FIXME
2995 * findvar.c (find_saved_register): Avoid problem in current frame.
2996 (read_relative_register): Ditto.
2997 (write_register): Convert byte order on the way out.
2999 * exec.c (file_command): Add.
3000 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
3001 (xfer_memory): Common function between core_xfer_memory and
3003 (exec_xfer_memory): Use it.
3005 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
3007 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
3008 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
3009 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
3011 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
3013 Merge Intel 960 port of gdb, continuing...
3015 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
3016 symbol_file_command): Pass from_tty arg to hush 'em up.
3018 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
3019 Add magic numbers for 960 COFF format.
3021 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
3023 Merge Intel 960 port of gdb, from Intel "1.2" release.

3042 "-se" switches as soon as they are encountered on the invocation line.
3044 Fri Apr 20 13:47:15 PDT 1990
3047 Thu Apr 19 09:54:28 PDT 1990
3048 Add 'reset' command.
3050 Wed Apr 18 09:48:07 PDT 1990
3051 After opening remote tty, wait for 1 second to go by without input
3052 from it before trying to talk to NINDY (fixes problems with the
3053 Heurikon HK80/V960E).
3055 Mon Apr 4 16:33:05 PDT 1990
3056 Some output was not being suppressed in 'batch' mode.
3058 Thu Mar 22 15:31:11 PST 1990
3059 Ask user if old symbol table should be deleted when new file is
3062 Allow user to run a program downloaded before gdb960 was brought up.
3064 Correct "exec-file" help message for i80960 context.

3074 code loaded at addresses higher than 0x7fffffff.
3076 Wed Jan 10 12:43:22 PST 1990
3077 Open remote tty for exclusive use.
3079 Fri Jan 5 12:14:42 PST 1990

3081 opcode for sysctl is 0x659
3083 Mon Oct 23 12:03:04 PDT 1989
3084 Use G960BASE and G960BIN environment variables to find 'sx' utility.
3086 Mon Oct 16 14:15:09 PDT 1989
3087 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
3089 Mon Oct 2 15:56:31 PDT 1989
3091 Added 960CA disassembly support.
3093 To simplify maintenance:
3094 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
3096 - eliminated opcode.h: incorporates tables into i960-pinsn.c
3097 - moved 960-specific routines from i960-pinsn.c to i960-md.c
3098 - made disassembly interface identical to that in gdmp960.
3102 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
3104 * target.h: Allow targets to stack. Add target_has_memory,
3105 _registers, etc. Restructure memory access and "info files"
3106 to walk the target stack.
3107 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
3108 target.c: Change tables to match target.h.
3109 * inflow.c (child_mourn_inferior): pop child_ops.
3110 (generic_mourn_inferior): Use new has_stack flag.
3111 * infptrace.c (child_xfer_memory): New memory regime.
3112 * inftarg.c (child_files_info): New "info files" regime.
3113 * remote-eb.c: New memory regime, new info files.
3114 * remote-vx.c: New memory regime, new info files. Now use
3115 separate targets for VxWorks attachment to machine, and
3116 actually running a process under VxWorks, since one has
3117 stack & execution & regs and the other doesn't.
3118 * remote.c: New memory regime, new info files.
3119 * sparc-xdep.c (fetch_core-registers): New memory regime.
3120 * target.c: New routines and support for stacked targets,
3121 new memory regime, new info files regime.
3124 Generalize section handling for an arbitrary number of sections,
3125 including use of the new BFD (binary file) library.
3126 * gdbcore.h: Add struct section_table.
3127 * exec.c (build_section_table): Iterate all sections and
3128 record what gdb needs to know about them.
3129 (exec_command): Use it.
3130 (exec_xfer_memory): Use the table.
3131 (exec_files_info): Print the table.
3132 * core.c (core_file_command, core_xfer_memory, core_files_info):
3134 * source.c (find_source_lines): Use bfd_get_mtime.
3135 * dbxread.c: Quick changes to make it compile with new BFD.
3136 * utils.c (error): Avoid using bfd_error in generic routines.
3138 * core.c (core_fetch_registers): Get from the ".regs" section of
3140 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
3142 * inferior.h (attach_flag): Export.
3143 * infcmd.c (run_command): use new target_create_inferior.
3144 * infrun.c (child_create_inferior): Don't return result.
3145 * Makefile.dist (VERSION): 3.91.4.
3147 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
3149 * breakpoint.c (bpstat_num): Handle breakpoints which have
3150 since been deleted, such as temporary breakpoints.
3151 infcmd.c (program_info): ditto.
3153 * core.c (core_file_command): Display the frame where the core
3158 * remote-vx.c (target_command): Merge in target command from
3159 targ-vx.c. A few other cleanups.
3161 * TODO, Projects: Lots more stuff to do...
3163 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
3165 Massive changes to wall off the remote-debugging interface
3166 behind a function vector. The port to handle VxWorks targets
3167 is also part of this.
3169 All files: Replace references to renamed functions,
3170 remove references to remote_debugging, remove references to
3171 have_include_file, have_core_file in favor of target_has_stack,
3172 target_has_memory, etc.
3174 * Modularize the breakpoint interface.
3175 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
3176 a breakpoint instruction.
3177 breakpoint.c: struct breakpoint's shadow_contents now sized as
3179 (insert_breakpoints): Vector to target to install breakpoints.
3180 (remove_breakpoints): Vector to target here too.
3181 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
3182 sparc-tdep.c (single_step): Use new breakpoint interface for
3183 the single-step breakpoints.
3184 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
3185 New file, contains routines to insert and remove breakpoints by
3186 reading out the old contents and later replacing them. This is
3187 how ptrace breakpoints work, and many remote systems as well.
3189 * tm-vxworks68.h: New config file, overrides a few things for
3190 Wind River's preferences.
3192 * target.h: New file, for transfer vector used to talk to the
3193 inferior (child, attached, core, exec, remote, etc). All accesses
3194 to the thing being debugged should come through these vectors.
3195 target.c: New file, routines to handle transfer vector.
3196 (various files): Add transfer vectors XXX_ops for the various
3197 targets and pseudo-targets (core files, etc) we support.
3199 * breakpoint.c (bpstat_stop_status): Further explorations of
3200 watchpoints and why things don't work all the time.
3201 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3203 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3204 the local gdbinit if it doesn't already have it.
3206 * core.c (core_ops): add and install.
3207 Allow core debugging without exec file.
3209 * dbxread.c (free_and_init_header_files): Merge two fns.
3210 (end_symtab): Free named symbol table when a new version comes in.
3211 (read_dbx_symtab): Relocate all kinds of symbols with base
3212 address. First step toward handling different text, data, bss
3214 (add_file_addr_command): Renamed add_file_command.
3215 (add_file_command): Vector to remote handler.
3216 Add "load" as an alias for "add-file" command.
3218 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3219 non-returning functions.
3221 * exec.c: Add exec_ops, and push it as a target when an exec
3224 * infcmd.c (run_command): Pass executable file name and arg list
3225 separately when starting an inferior. Permit "run" when no exec
3226 file is specified, for VxWorks.
3227 (detach_command): Move to child_detach in inftarg.c.
3229 * inftarg.c: New file. Unix-child-specific routines, and the
3230 child_ops structure.
3232 * inferior.h (registers): Export "registers" as the way for
3233 target dependent register handlers to find gdb's local copy of
3234 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3235 since it is now used by places that want wait_for_inferior to
3236 handle the grunge but want to see every trap from the inferior.
3238 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3239 Eliminate remote_debugging hooks in terminal handling.
3241 * infrun.c: Replace start_inferior with child_create_inferior.
3242 Move all the hair of Unix shells and ptrace idiosyncracies into
3243 child_create_inferior, so remote handlers don't have to deal.
3244 Remove running_in_shell. Rename stop_after_attach to
3245 stop_soon_quietly, and use it in a few other places where we want
3246 to just call wait_for_inferior and get control back on the first
3247 trap. trap_expected now never takes a value > 1.
3248 (init_wait_for_inferior): Initialize static vars when a new
3251 main.c (gdbinit): Add new hook for .gdbinit file name, let
3252 it be overridden by config files as GDBINIT_FILENAME.
3253 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3254 Both of these are used for VxWorks gdb.
3256 mcheck.c: rename include file "gmalloc.c" to avoid problems
3257 with system include file "malloc.c".
3259 param-no-tm.h: New include file, same as param.h but does not
3260 include the default "tm.h" file. This is used in files where
3261 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3263 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3265 remote-vx.c: New file, VxWorks remote debugging support. Uses
3266 RPC routines that are shared with the target system, in directory
3269 remote.c: Vectorize remote interface.
3271 source.c: Globalize source_path, and make an alias "l" for "list"
3272 since we now have the "load" command.
3274 sparc-xdep.c: Use new param-no-tm.h.
3276 symmisc.c (free_named_symtab): Add new function from Wind River.
3277 However, ifdef it out for now while we think about what it should
3280 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3282 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3283 non-Unix-children handle this with their own code in the target
3286 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3287 source and target lists. Add vx-share to default list of include
3288 directories. Add new files to src and target lists: mem-break,
3289 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3290 ${srcdir} versions of munch and createtags are used.
3292 * valops.c (find_function_addr): Split out of call_function.
3293 (call_function_by_hand): Rename call_function; this function
3294 calls functions in the target by laboriously patching the target
3295 word-by-word with the right stack, args, regs, etc.
3298 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3300 Handle AMD 29000 a bit better.
3302 * remote-eb.c (readchar): Mask received char log to make it readable.
3303 (remote_start): Pass arguments down to executing program.
3304 Make startaddr unsigned.
3305 infrun.c (start_inferior): Accept args, pass them to
3307 infcmd.c (run_command): Pass args down to start_inferior.
3309 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3310 the target object file format.
3311 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3313 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3314 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3316 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3318 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3319 * TODO: We did a few things, we have more to do though.
3321 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3322 * inflow.c (inferior_died): Clear deferred stores.
3324 * Debug problems with dummy frames and calls to the inferior.
3325 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
3326 * sparc-tdep.c (do_restore_insn): Simplify.
3327 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3328 (sparc_push_dummy_frame): Simplify and fix what we push.
3329 (sparc_pop_frame): Slightly more hair here, deciding whether
3330 we are restoring a saved PC or returning to a return address in %i7.
3331 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3333 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3334 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3335 * obstack.h (chunkfun): ditto.
3336 * defs.h (xmalloc, xrealloc): ditto
3338 * utils.c (quit): Grab the terminal from the child if necessary.
3340 * inflow.c (term_status_command): Rename to term_info, change
3343 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3344 (is_delayed_branch): Speed up.
3345 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3346 Still missing some float ops, and needs testing.
3348 * Support for input and output radixes other than base 10
3349 * defs.h (input_radix, output_radix): Declare.
3350 * expread.y (yyparse, parse_number): Handle changes of input
3351 radix, and ambiguous names-or-numbers in radixes >10.
3352 * printcmd.c (print_scalar_formatted): Print formatted hex
3353 numbers in varying column widths.
3354 * valprint.c (val_print): Use output_format to print scalar ints.
3355 (set_input_radix, set_output_radix, set_radix): Create.
3356 (set_output_radix): Set output_format from output_radix.
3357 (_initialize_valprint): add `set radix' but leave the others off.
3359 * main.c (execute_command): Let stupid questions be turned off.
3360 (_initialize_main): Handle "set stupidity", etc.
3362 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3363 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3365 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3367 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3368 bfd stuff is still screwed up, but with some manual work, it
3371 * breakpoint.c (bpstat_do_actions): Start over if a command
3372 proceeds the inferior, since the inferior will have stopped and
3373 will need to have its new stop-actions taken care of.
3375 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3376 compiler fits, simplify it.
3378 * gdb.texinfo (directory command): Doc new dir command.
3379 source.c (directory_command): "dir" now puts things on the front
3380 of the path, moves dups up front, and handles multiple names
3381 on the command line, inserting each one in order. It also
3382 blows away cached line and full_filename info.
3384 * stack.c (backtrace_command): Skip "more stack frames follow"
3387 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3388 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3389 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3390 The only odd one was Gould NP1, which had defined vprintf to
3393 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3394 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3395 variable, inspect_it.
3396 valprint.c (print_string, val_print): Use the global inspect_it
3397 to indicate whether to print in Epoch style or normal style.
3399 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3401 * printcmd.c (call_command): add an alias for the "print" command
3402 which runs expressions and doesn't print the result if void.
3403 (print_command_1): implement it.
3405 * command.c: Remove #if 0'd code. Initialize all the fields
3406 in add_cmd (). Rename do_nothing_command to
3407 not_just_help_class_command, and make it externally visible.
3408 command.h: add user_commands to struct.
3409 * main.c (define_command): Don't overload c->function with a char
3410 string as well as a function pointer.
3412 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3413 calling convention of value_struct_elt () that got dropped in
3416 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3417 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3419 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3421 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3422 until a good time (e.g. when we are about to run the child),
3423 saving ptrace calls.
3424 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3425 * tm-sparc.h: define DO_DEFERRED_STORES.
3427 * sparc-xdep.c (store_inferior_registers): when storing float
3428 registers, don't store stack regs too. When storing the SP,
3429 however, DO store the stack regs too. This fixes a bug in which
3430 the dummy frame is not recognized when a call_function finishes,
3431 because its frame pointer (in the stack regs) was never
3433 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3434 even though we don't know how to read them from an inferior.
3435 valops.c (call_function): Comment about storing SP.
3437 * infrun.c (save_inferior_status): Save away the original bpstat
3438 chain so it can be restored later. Install the copied version for
3439 use by whoever saved the status. It will be blow away by
3440 restore_inferior_status, and the original chain restored. This is
3441 important for people who have pointers into the original.
3443 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3444 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3445 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3448 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3450 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3451 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3452 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3454 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3456 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3457 Store the baseclasses in a type struct starting from array element
3458 0 rather than from the unusual array element 1.
3460 dbxread.c: the above.
3461 (virtual_context): Add
3462 Read new debug information about which virtual function table
3463 a virtual function is from, and store it in fn_field.fcontext.
3465 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3466 TYPE_FN_FIELD_STATIC_P.
3468 symtab.c: the above.
3469 valops.c: the above. Handle pointer casts of object *'s.
3470 (search_struct_method): Add.
3471 (value_struct_elt): First arg is now a pointer to a value, and is
3474 valprint.c: the above.
3475 values.c (value_virtual_fn_field): Add type arg. Handle
3476 offsetting to the proper object when calling virtual fns.
3478 (baseclass_addr): Add valuep arg.
3480 * README: Document the current state of BFD config (missing).
3481 * TODO, ChangeLog, Makefile.dist: Roll version.
3482 * WHATS.NEW: Add summary of changes since 3.5.
3484 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3486 * dbxread.c (read_struct_type): Clear bit vectors whenever
3488 symtab.c (B_CLRALL): define.
3490 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3491 using == rather than =. Huh... This fixes the dreaded problem
3492 wherein builtin_type_int becomes TYPE_CODE_FLT.
3494 * core.c (info_files): Show the inferior pid.
3496 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3497 already knows how to look in the source directory.
3499 * Remove psymtab hair from many places. Remove duplicated code
3500 for searching symbol tables. Hide psymtabs from most places.
3501 Make it fast to get from a psymtab to its symtab.
3503 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3504 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3505 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3506 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3507 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3508 new symtab completely. New psymtabs get symtab pointer
3509 initialized to zero. Remove MI warning printf.
3510 symtab.h: Comments. Add psymtab to symtab pointer.
3511 (PSYMTAB_TO_SYMTAB): New macro.
3512 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3513 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3515 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3517 (print_frame_info): Avoid special-casing symbols that have not yet
3520 * source.c (open_source_file): Quick path if we have already
3521 located the source file by its full name.
3523 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3524 find_pc_psymtab. When a name is found in the misc function
3525 vector, search the symbol table for its mangled name, not the
3526 name that the user typed.
3528 * bfd.h: Fix missing comment terminators, make #endifs match.
3530 * valarith.c (value_less): Handle unsigned int comparisons.
3531 Add FIXME about pointer compares, which assume host and target
3532 pointers are the same.
3534 * command.c (do_nothing_command): lint
3535 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3536 fix comments on debug symbol format for visibility. Actually set
3537 visibility of symbols.
3538 main.c (echo_command): lint; use <readline/history.h>.
3539 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3540 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3541 pointing past end of allocated memory; saber complains.
3542 obstack.h: Declare the external functions that we use.
3543 valarith.h: use <string.h>
3544 solib.c (solib_add): lint.
3546 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3548 * main.c (initialize_main): Default info_verbose to off, now that
3549 symbol reading is fast.
3550 (quit_command): Avoid clobbering exec_bfd while quitting.
3552 * Initial BFD (binary file diddling library) merger:
3553 coffread.c: Change AOUTHDR to struct exe_hdr.
3555 core.c: initialize initialized data at compile time.
3556 (core_file_command): Move from coredep.c, convert to bfd.
3557 (xfer_core_file): Convert to bfd.
3558 exec.c (exec_file_command): use bfd routines.
3560 mips-tdep.c: Remove exec_file_command and friends.
3563 * coredep.c: (fetch_core_registers) Convert core_file_command to
3564 fetch_core_registers.
3565 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3567 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3568 (my_bfd_read): More bogosity, which I don't think we call.
3569 (program_name): Remove this atrocity asap!
3571 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3574 values.c: allocate_repeat_value was not clearing the
3575 optimized_out field.
3576 (value_static_field): minor stylistic fix (wrong macro was used).
3577 valops.c (value_struct_elt_for_address): didn't work for C++
3580 * signame.c (_initialize_signame): Initialize signal names once.
3582 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3583 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3584 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3586 * remote-eb.c: Support user-settable baud rates on the serial port.
3588 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3590 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3592 * tconfig/sun3os4: Remove warning about native assembler,
3593 since it also occurs in the xconfig file.
3595 * findvar.c (registers): Allocate some slop after `registers'
3596 to prevent stray accesses from trashing the next variable.
3598 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3599 on the sun-3, by changing the #ifdef from `sun3' (which is not
3600 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3601 vars, which happened to follow `registers' in the executable.
3603 * readline/history.c (history_search): Heed gcc-2's advice
3604 and parenthesize && inside ||).
3606 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3607 tm-29k.c: Insert FSF copyright headers.
3609 * remote-eb.c: Better comments.
3611 * Makefile.dist: Update to 3.91.6.
3612 * TODO: note PREPARE_TO_STORE problem.
3614 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3616 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3618 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3620 * infrun.c (wait_for_inferior, at end): Don't set up
3621 prev_* if the inferior no longer exists.
3623 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3624 CANNOT_EXECUTE_STACK.
3625 valops.c (call_function): Use it.
3627 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3629 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3630 infrun.c (wait_for_inferior, 2 places): Use it.
3632 * values.c (value_being_returned): Only use
3633 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3635 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3636 right thing for remote-eb.c.
3638 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3639 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3641 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3642 (FRAME_FIND_SAVED_REGS).
3644 * findvar.c ({fetch,store}_registers): Check for
3645 REMOTE_{FETCH_STORE}_REGISTER macro.
3647 * findvar.c (get_saved_register): Add argument lval and
3648 change meaning of argument addr.
3649 findvar.c: Change calls to get_saved_register to reflect
3650 new calling convention.
3651 valops.c (value_assign): Use get_saved_register instead of
3652 find_saved_register.
3654 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3656 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3657 an (uninitialized) pointer to one. Use "&" when passing it
3660 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3662 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3665 * coffread.c (symbol_file_command): Put semicolon after
3667 Put safe_to_init_tdesc_context in #if defined (TDESC).
3668 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3669 coffread.c: #include <sys/stat.h>.
3670 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3671 Add missing ')' in check for "lc%" and friends. Remove
3673 Declare read_one_sym() at top of file.
3674 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3675 MC68WRMAGIC can have the same value without causing a duplicate
3678 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3680 * Allow a Makefile to be built without building the
3681 tm and xm file links that screw up builds in subdirectories.
3682 This is done with `config.gdb none', then you can do things
3683 like `make gdb.tar.Z'.
3684 * tconfig/none: Config file for no target system
3685 * xconfig/none: Config file for no host system
3686 * config.gdb: If no TM or XM files are called out by the
3687 host or target file, don't make links for them.
3689 * cplus-dem.c: Add documentation.
3691 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3692 simple error, so the user's gdb doesn't crash due to some object
3693 file problem (e.g. somebody is rebuilding the file out from under
3696 * printcmd.c (print_address_symbolic): demangle the symbol.
3698 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3699 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3700 (alldeps.mak): sort and uniq all results from this; duplicates
3701 hose gdb.tar.Z link building. Remove RCS files from
3702 tconfig and xconfig. Add config files for sun386. Add
3703 a few odd files to OTHERS and HFILES.
3705 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3707 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3708 Roll version number to 3.91.5. Make lint work in bindir.
3710 * README: Document cross-debugging and new file structure.
3712 * blockframe.c: Lint. Include "value.h" to declare read_register.
3713 (find_pc_partial_function): remove duplicate line.
3715 * command.h: Lint. Declare error_no_arg and dont_repeat.
3717 * tm-news.h: Remove inadvertently duplicated stuff.
3719 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3720 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3722 * config.gdb: Allow `config.gdb host target' form. Clean
3723 up previous change that printed bogus messages when you just said
3726 * core.c: #include "command.h" for lint.
3729 * main.c: Remove some casts of enums. Lint.
3736 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3738 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3739 read it from memory. This will allow us to save ptrace calls
3740 eventually. Changed caller single_step too.
3742 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3743 that we aren't going to use, saving many ptrace calls, especially
3744 when watchpointing or single stepping. Use some #define's for
3746 (store_inferior_registers): Ditto.
3747 (core_file_command): Use some #define's for constants.
3749 * tm-sparc.h: Add #define's for some register numbers, so we
3750 can eliminate the use of random constants in sparc-xdep.c.
3752 * stack.c (frame_command, print_frame_info, up_command,
3753 down_command) Remove frame_changed, since it
3754 causes a bug and doesn't seem to do anything useful. In some
3755 places it was used as a flag, in others as a stack level (?).
3757 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3758 default is to use the portable (vprintf) version rather than the
3760 * xm-news.h (MISSING_VPRINTF): Add.
3762 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3764 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3766 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3767 about linking debugged programs -Bstatic in the sun?os4 config
3768 files in tconfig and xconfig subdirectories.
3770 * main.c (main): Remove unreached exit(0) now that we exit
3773 * Create TODO file for online bug list. There are too many
3774 "little" bugs to keep track of on paper.
3776 * Change Projects file to refer to bug-gdb@cygnus.com
3777 rather than kingdon@ai.
3779 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3781 * Makefile.dist (VERSION): 3.91.4 now.
3783 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3784 (condense_misc_bunches): Add sanity check that misc_count is
3785 the same as the number of symbols in the bunch.
3787 * coffread.c: rename init_misc_bunches. Pass an argument
3788 to condense_misc_bunches (a zero).
3790 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3791 every time we are called; don't rely on our caller to do it.
3792 (add_file): Remove call to init_misc_bunches.
3794 * mipsread.c: Only warn, don't error, if unknown symbol types.
3795 This keeps an old gdb from falling on its face if it sees newly
3796 extended symbol info. Rename init_misc_bunches.
3798 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3800 * Merge in changes from Per Bothner for DECstations and other
3801 MIPS stuff. The rest is Bothner speaking:
3803 The next message is a merger of Alessando Forin's mips port with
3804 mine. I've tried to use my good if biased judgment to get
3805 the best of both. It *does* need testing.
3807 Some of the changes are general, *not* mips-specific.
3810 Didn't believe in little-endian bit order.
3811 There are still inconsistencies about whether flags
3812 like BITS_BIG_ENDIAN are integer (#if ...) or
3813 boolean (#ifdef ...). I tried to paper over them.
3815 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3816 Moved some misc_function code that was common to
3817 {dbx,coff,mips}read.c to symtab.c.
3818 In the process, I think I cleaned things up a bit.
3819 At the same time, moved obsavestring and obconcat to symtab.c.
3822 Removed obsolete condense_addl_misc_bunches (use
3823 condense_misc_bunches(1) instead).
3826 Needed to include <sys/dir>, at least on DECstations.
3828 valops.c, mips-tdep.c, tm-mips.h:
3829 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3830 conventions (when STACK_ALIGN is insufficient).
3831 Needed on mips, where doubles need 8-byte alignment,
3832 but ints only need 4.
3835 Removed cruft that was not being used.
3836 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3839 Print $ before register-names (I think that makes things a little
3841 Never print two instructions, even if one delays.
3842 Removed hex-disassemble set_cmd. (This is not mips-specific,
3843 so I think the argument is whether it is generally worthwhile or not.
3844 I'm inclined to think not, given how easy it is to
3845 convert between radixes in gdb.)
3848 This is basically Alessando's code.
3849 It doesn't use obstacks; I changed it to use obstacks
3850 in a few minor places where using malloc causes a
3851 memory leak. (Probably, more places could/should be changed.)
3852 I added record_misc_function where it was missing.
3853 In symbol_file_command and add_file_command, I tried
3854 to make the code consistent with more recent versions.
3855 Minor sylistic changes in parse_procedure.
3856 Make a .gdbinfo. psuedo-symbol point back to the real
3857 procedure symbol (using the isym field).
3860 This is basically from my port, but with a lot of details
3861 and a number of routines merged in from Alessando's version.
3862 I basically used my code "raw" backtrace (use heuristics
3863 from the actual code, rather than symbol table info) - though
3864 the idea is Alessandro's. I feel my code is a little cleaner
3865 here, particularly in being a little more flexible, such as being
3866 able to handle gcc-produced code (which it now can).
3867 It also doesn't do frame caching (which is not useful
3868 more recent gdb versions).
3869 I also used my code for push_/pop_dummy, more or less.
3870 I tried to incorporate AF's code for testing sigtramp
3871 while backtracing; I probably got it wrong.
3872 Added mips_print_register, which tries to scrunch as much
3873 information as possible on a screen...
3874 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3875 under mips-pinsn.c), I don't see anything mips-specific here,
3876 and I don't see it being all that useful anyway.
3879 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3880 Use more register names (rather than hard-cases numbers).
3882 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3884 * Hack up 3.90.11 changes:
3886 * Makefile.dist (depend): parameterize $(GCC).
3887 Add solib.c and solib.o.
3888 (readline): Fix vpath for both absolute or relative SRCDIR.
3890 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3891 Also, let the part I didn't understand at least compile so
3892 I can test the rest. FIXME.
3894 * dbxread.c: Fix thinko using strcmp.
3895 (init_psymbol_list): declare static.
3896 (partial_symbol_file_open): Comment cleanups better, avoid
3897 cleaning up the string table since the caller will do that.
3898 Move the stat for mod time into symbol_file_command, temporarily.
3899 (There should be a mod time for each symbol file, eventually,
3900 to control its rereading. FIXME.)
3902 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3903 SunOS, which gives error for shared libs otherwise. (From
3904 Schaefer, probably FIXME needs work for portability.)
3906 * solib.c: Move #include "param.h" to work.
3907 Lowercase all the Uppercase Letters In the Messages.
3908 (find_solib): Clean up inferior_so_name for debug printouts.
3909 Allow no argument, to mean all shared libraries.
3911 * symmisc.c: include param.h to get CLEAR_SOLIB.
3913 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3915 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
3916 to 3.90.11. ChangeLog entries below are from this.

3945 * Changes for Sun shared libraries:
3946 blockframe.c (find_pc_partial_function): If a non-text symbol
3947 is found, set *address = pc - FUNCTION_START_OFFSET.
3948 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
3949 Disable breakpoints instead of giving an error.
3950 source.c (select_source_symtab): Initialize cs_pst.

3953 (psymtab): New field addr.
3955 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
3956 (record_misc_function): Give correct type for N_DATA symbols.
3957 (condense_misc_bunches): do "misc_function_count = j" regardless
3959 Take code which is shared between symbol_file_command and
3960 add_file_command and put it into partial_symbol_file_{open,read}.
3961 Split add_file_command into add_file_command and add_file.
3962 Make psymtab_to_symtab read in the string table if the file
3964 Two new parameters to read_dbx_symtab and start_psymtab.
3965 tm-sunos.h: New file.
3967 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3969 * infcmd.c: Change cont_command to continue_command and "cont"
3972 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3974 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
3976 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
3978 * values.c (USE_STRUCT_CONVENTION): Check for structures of
3979 size 1,2,4,8 rather than size < 8.
3981 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
3982 as necessary, not just once.
3984 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3986 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3988 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3990 * tm-news.h: Add CALL_DUMMY_*.
3992 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
3994 * config.gdb: In list_host, list_target, use ${i}, not $i.
3996 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3998 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
4000 * sparc-opcode.h: Change all store floating-point state register
4001 instructions to have the right match & lose fields.
4003 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4005 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
4007 config.gdb: If srcdir != ., create readline directory and
4008 copy a makefile into it.
4010 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
4011 consistency with POSIX.
4013 * breakpoint.c (bpstat_stop_status): Disable watchpoint
4014 when we exit its exp_valid_block.
4016 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
4018 * Makefile.dist: Bump version to 3.91.3.
4020 * Clean up handling of breakpoint commands (somewhat).
4021 Prompted by Tiemann bug report "cont 10" doesn't work any more.
4023 inferior.h: Add breakpoint_proceeded to inferior status struct
4024 and globals; save it and restore it.
4025 (clear_breakpoint_commands): Cleanup, remove old #define.
4027 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
4028 (save_inferior_status, restore_inferior_status): handle it also.
4029 (proceed): Remove earlier code that set breakpoint_proceeded.
4030 It is now set only in clear_proceed_status.
4031 (clear_proceed_status): Cleanup, use bpstat_clear rather
4032 than clear_breakpoint_commands. No callers need the stop_bpstat
4033 between clear_proceed_status and proceed.
4035 infcmd.c: Add breakpoint_proceeded definition and comment.
4036 (cont_command, jump_command, signal_command): Move call to
4037 clear_proceed_status right next to call to proceed.
4039 breakpoint.c (bpstat_do_actions): Avoid clobbering our
4040 caller's argument while running down the chain of breakpoints.
4041 Use new variable "breakpoint_proceeded" to determine when
4042 a command that it executes moves the inferior past the
4044 (bpstat_clear): Handle NULL argument.
4045 (bpstat_clear_actions): Avoid useless call to
4046 breakpoint_auto_delete.
4047 (delete_breakpoint): Clean up bpstat's that are pointing to
4048 the deleted breakpoint from the stop_bpstat chain.
4049 (breakpoint_auto_delete): Simplify.
4051 * Clean up handling of EOF, error on stdin, etc. This was
4052 prompted by a network problem that caused gdb to go into an
4053 infinite loop filling up its malloc'd memory.
4055 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
4056 not clear_breakpoints_commands, which is now gone.
4057 (main): If command_loop returns (e.g. from EOF on stdin), do
4058 a quit_command (looping back to command_loop if quit_command
4059 doesn't really quit).
4060 (command_loop): check result from command_line_input and
4061 exit if it returns NULL, rather than passing the NULL to
4063 (gdb_readline): Free malloc'd result space before returning
4066 * utils.c (query): Handle C-d to mean "yes", just as if the
4067 input was not a terminal. Also avoid infinite loop if EOF
4068 occurs in mid-input-line before newline. This allows
4069 query to be used at EOF on stdin with reasonable results.
4071 * infrun.c (proceed): Set breakpoint_proceeded.
4073 * values.c (value_as_long): Avoid infinite recursion for enums.
4074 (_initialize_values): Fix typo in help msg (kingdon).
4076 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
4077 RL_LIB for linking. This allows -lreadline for linking
4078 and nothing for dependencies, once readline is a real library.
4080 * config.gdb: Jim Kingdon: give useful error message if the
4081 host or target type is not recognized.
4083 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
4084 it just defines it. Dumb, but deal with it.
4086 * Jim Kingdon suggests:
4087 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
4089 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
4091 * Makefile.dist (VERSION): Bump version # to 3.91.2.
4093 * Clean up Bothner's changes.
4095 * blockframe.c (clear_pc_function_cache): New function.
4096 * blockframe.c: remake cache_pc_function_* static.
4097 * dbxread.c (symbol_file_command): remove references to
4098 cache_pc_function_* variables.
4099 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
4100 * printcmd.c: Avoid kludging a global variable (addressprint)
4101 to avoid printing the address of a string twice. Instead,
4102 pass the format letter 's' down low enough that it can be seen
4103 to avoid this problem.
4104 (print_formatted): Pass format arg to value_print.
4105 (restore_addressprint): Remove function.
4106 (do_examine): Avoid hacking addressprint, cleanups and such.
4107 (print_frame_args): Add a comment to a Bothner change.
4108 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
4109 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
4110 to wipe out the values cached in blockframe.c.
4111 * symtab.c (find_method): Add comment saying how big you must
4112 allocate to be "big enough". Per being terse again.
4113 * valprint.c (val_print): Handle format letter "s" to print
4114 strings without addresses. Add comment to vtbl printing code
4115 which casts with wild abandon. Rearrange reference-printing
4117 @0xaddr: value (print w/addressprint)
4118 value (print w/~addressprint)
4119 @0xaddr (parameter lists w/addressprint)
4120 or nothing (parameter lists w/o addressprint)
4122 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
4124 * Merge more changes from Per Bothner:
4126 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
4127 annoying) that I tried to improve it. Here are my suggestions.
4129 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
4132 Do automatic de-reference when taking the address of a reference.
4134 Don't deref_ref when printing parameter lists.
4136 More attempts at treating refernences properly.
4138 In val_print, if deref_ref==0, don't print dangling " = ".
4140 Add COERCE_REF macro, which de-references an REF.
4142 * Merge changes from Per Bothner:
4144 * Fixed (Sony news)-specific configuration problems.
4145 * Fixed other problems with using vanilla pcc and libc (enum problems;
4146 assumption that vsprintf exists).
4147 * Some major speed-ups (finc_pc_partial_function now caches a match;
4148 parsing avoids duplicate symbol_lookup calls).
4149 * Changed handling of baseclasses (no longer use baseclasses field
4150 of struct type, use the first n_baseclasses fields instead).
4151 * Various minor changes/fixes, most C++-related.
4154 Cache the most previous match from find_pc_partial_function.
4155 (Save both low and high ends of matching function's pc range.)
4156 This speeds up the loop of infrun.c:wait_for_inferior quite
4157 a bit, and makes step/next commands much zippier.
4159 Added an enum->int cast (otherwise, some compilers barf).
4161 No longer set baseclass offset to 0, since multiple
4162 inheritance now mostly works.
4163 Added a number of casts, to shut up compiler warnings
4164 (after stabs where made enums, not ints).
4165 When discarding a symbol table (in symbol_file_command),
4166 must clear the cache introduced in blockframe.c.
4167 Don't convert $vtbl_ptr_type to vtbl any more.
4168 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
4169 Mask off sign bit emitted by g++ for virtual table offset.
4170 Set voffset to -1 (not 1) for static member functions.
4172 Changed parsing/lexing of names to avoid doing symbol lookup twice
4173 (once when lexing to determine symbol class, once for real).
4174 Now only call symbol_lookup once. Fields of 'this' win especially big.
4176 Subpress printing addr twice in the case of 'x/s addr'.
4178 lookup_basetype_type is no longer used.
4179 Add find_methods as recursive helper function to decode_line_1.
4180 This allows multiple inheritance to work.
4181 Also, once one or more matches has been found, do not look in
4182 base-classes. (Baseclass methods would be overridden, anyway.)
4184 Removed baseclasses array in struct type.
4185 Instead of using baseclasses[i], use fields[i-1].
4186 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
4187 Changed sign convention of voffset (previous was inconsistent).
4189 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4191 Used to assume existence of vsprintf. Re-written to not need it
4192 if HAVE_VPRINTF is undefined.
4194 typecmp was too pessimistic. Made it less so.
4196 Don't print space after address.
4197 If vtable points to a misc symbol (with 0 offset), print it,
4198 since that indicates the actual class of the object.
4199 Changed ype_print_derivation_info to use new inheritance
4200 scheme (without baseclasses vector).
4202 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4203 Also, changes needed because TYPE_BASECLASSES were removed.
4205 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4207 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4210 If there is no path set, and the symbols don't indicate what directory
4211 a file was compiled in, look in the current directory. But either
4212 a path or a known compilation directory will prevent this.
4215 Three independent bug fixes:
4216 * Remove the #if 0 block that breaks some stuff.
4217 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4218 adapt gdb to either SunOS 4.0.* or 4.1.
4219 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4222 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4225 (type_print) Demangle the name being printed.
4226 (type_print_base) Handle botched demangling without coredump (tiemann).
4229 (check_stub_method): Document routine.
4230 (tiemann) fix bug for no-arg functions
4231 Avoid clobbering beyond end of malloc'd storage.
4232 Terminate the argument list properly.
4234 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4236 * Changes merged by John Gilmore:
4239 In breakpoint_1, use new print_address_symbolic instead
4240 of find_pc_partial_function. (This forces use of assembler-level
4241 addresses, and avoids misleading non-mangled source-level names.)
4243 Generalize ansi argument such that -1 means skip arglist totally.
4244 Removed global variable print_ansi_qualifiers (which made
4245 code non-reentrant), in favor of extra explicit arguments
4246 to internal routines.
4248 Add new helper function print_address_symbolic.
4249 Use find_pc_misc_function instead of find_pc_partial_function
4250 (since we want assembler-level symbols here).
4252 Print unknown function as just "f (...)", not "f (...) (...)".
4253 Use new fputs_demangled explicitly.
4255 Fixed a typing violation (problem: value.h cannot be imported
4256 without renaming many variable in this file).
4257 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4258 decode_line_1: Moved forward some never-reached code.
4259 Made decode_line_2 skip function prologues correctly.
4261 fputs_filtered should not demangle by default.
4262 Add new fputs_demangled to demangle on demand..
4264 Change value_struct_elt to use value_primitive_field (using recursive
4265 utility function search_struct_field). This allows foo.bar to work
4266 for multiple inheritance (so far only for data fields).
4267 Change check_field in the same way (recursive helper function
4268 to support multiple inheritance).
4269 (Note: there are more of these problems that I haven't fixed.
4270 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4271 value_of_this: 'this' symbol name is now just "this", note "$this".
4273 Don't print static members.
4274 Avoid printing "members of <type>" if there are none.
4275 Simplified type_print_derivation_info by merging duplicate code.
4276 Remove useless blank lines in type_print_base (ptype command).
4278 Added declaration of new routine value_primitive_field.
4280 Added value_primitive_field which is generalized version of
4281 value_field that can handle multiple inheritance (non-zero offsets etc).
4282 Re-implemented value_field to call value_primitive_field.
4284 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
4286 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4287 delete the whole environment. Karl Berry reported the bug.
4288 * source.c - fix openp to avoid //'s in filenames, which
4289 trigger an Emacs bug causing it to not be able to find files
4290 when running gdb in a window.
4291 * dbxread.c - zap the #if 0 that botches the add-file code.
4292 It seems to work a lot better without all the code commented out.
4294 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
4296 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
4299 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
4301 * Makefile - added a ${CFLAGS} to a couple of entries,
4302 added remote-sa.sparc.c
4303 * added remote.sa-sparc.c, a modification of remote.c
4304 which conducts a dialog directly with the SparcStation prom.
4305 * breakpoint.c, infrun.c, sparcdep.c added
4306 remote_insert_breakpoint(), and remote_remove_breakpoint()
4307 to breakpoint.c instead of directly writing breakpoint instructions.
4308 * sparcdep.c on remote_debugging,there is no need
4309 to remove signle step breakpoint instructions.
4310 * main.c added "-epoch" flag and "int epoch_interface" to main.c
4312 * printcmd.c - epoch interface sends lisp expressions to open up
4313 epoch windows on inspection.
4314 * valprint.c - added arrayprint, and addressprint and made adding
4315 format controls easier
4316 * wait.h added a couple of undef's because we were getting
4317 complaints about WSTOPSIG and WTERMSIG begin redefined.
4320 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
4322 * symtab.c (decode_line_1): Add support for handling method stubs
4323 in the type information.
4325 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
4327 * values.c (baseclass_addr): Run loop from INDEX+1 to
4328 N_BASECLASSES; otherwise, we can still get into a loop.
4329 @@ This should be restructured to use a cleaner search strategy.
4331 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
4333 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
4334 abbreviation "Tt" for tags which have the same name as their
4337 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
4339 * symtab.c (list_symbols): add ability to set breakpoints on all
4340 the functions which match a particular regular expression.
4342 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
4344 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
4345 should print ANSI qualifiers (such as `const' and `volatile').
4346 All callers changed to call with ANSI == 1, except from
4347 `check_method_stub', which uses old-style syntax.
4349 * symseg.h (struct fn_field): Remove unneccessary `args' field.
4350 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
4352 * values.c (check_stub_method): New function.
4354 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
4356 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
4357 * valprint (type_print_base): Ditto.
4359 * symtab.c (gdb_mangle_typename): New function.
4361 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
4363 * breakpoint.c (catch_command): New function. Provides a
4364 mechanism to set breakpoints based on catch clauses.
4365 (disable_catch): Similar, but disables breakpoints on catch
4367 (delete_catch): Similar, but deleted breakpoints on catch clauses.
4369 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
4371 * blockframe.c (blockvector_for_pc): New function.
4372 * blockframe.c (block_for_pc): Changed to call
4373 `blockvector_for_pc' and get the block itself.
4375 * stack.c (catch_info): New function. Prints info about
4376 exceptions which can be caught in the current frame.
4377 * stack.c (print_frame_label_vars): New function. Similar to
4378 `print_frame_local_vars'.
4379 * stack.c (print_block_frame_labels): Prints out labels that are
4380 defined in this frame. These labels are exceptions that can be
4383 * dbxread.c: Updated to handle N_CATCH symtab types.
4385 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
4387 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
4388 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
4389 when printing the type.
4391 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
4393 * valprint.c (val_print): Use `baseclass_addr' to access the
4394 baseclasses pointed to via the derived class object at VALADDR.
4396 * values.c (baseclass_addr): New function. Casts derived pointers
4397 to baseclass pointers taking virtual baseclasses and multiple
4398 inheritance into account.
4400 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4404 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4406 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
4407 exp_valid_block field correctly.
4409 * infrun.c (wait_for_inferior): When checking "don't even think
4410 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
4411 also check step_resume_breakpoint.
4412 Insert breakpoints and continue (not step) if
4413 step_resume_break_address != NULL, even if another_trap.
4414 If trap_expected and we enter sigtramp, then set up a
4416 If trap_expected is set when we hit the step_resume_break,
4418 When calling resume and trap_expected says tell resume to step
4419 (2 places), also check step_resume_break_address.
4421 * infrun.c (wait_for_inferior): Don't set
4422 prev_{pc,sp,func_{start,name}} before calling wait ().
4423 Do set them after exiting loop.
4424 Move their declarations outside functions.
4425 (start_inferior): Initialize them.
4427 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4429 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
4430 Restore old code which distinguishes between trap_expected and
4431 running_in_shell, just make the latter take any non-TRAP signal,
4434 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
4436 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
4437 xconfig/3b1 (CC,PINSN_CC): Define.

4456 (printf_command): Add from_tty parameter.
4458 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
4460 * value.h: Add optimized_out field and change lazy field to
4461 char. Add macro VALUE_OPTIMIZED_OUT.
4463 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
4464 instead of stuffing things in buffers (oappend, etc).
4466 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
4467 execute_command, exit both loops.
4469 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
4471 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4473 * Makefile.dist (RAPP_OBS, rapp),
4474 rgdb.c, rserial.c, rudp.c, serial.c, udp.c, xdep.h,
4476 m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
4478 * valops.c (value_struct_elt), values.c (value_static_field):
4479 Change error messages to remove references to `info methods'.
4481 Tue Apr 24 10:25:10 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4484 infrun.c (start_inferior): Add START_INFERIOR_HOOK.
4485 infcmd.c [SHIFT_INST_REGS]: New code.
4486 findvar.c (read_relative_register_raw_bytes): Return a value.

4488 read_relative_register_raw_bytes.
4490 * command.c (delete_cmd): Free the struct cmd_list_element(s)
4493 Mon Apr 23 10:42:21 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4496 findvar.c (get_saved_register): New function.
4497 findvar.c: Rewrite code which called find_saved_register to
4498 call get_saved_register instead.
4500 Sun Apr 22 14:47:51 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4502 * valprint.c (val_print): Change error message printed when
4503 the type has TYPE_FLAG_STUB set.
4505 * valprint.c (val_print): Check for TYPE_CODE_UNDEF.
