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

502 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
504 * infptrace.c (fetch_registers): no result, since now void.
505 * tconfig/news: target depends on m68k-tdep too.
507 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
509 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
512 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
513 applied various small fixes due to or inspired by RMS comments
515 * doc/gdb.texinfo: finished using all RMS comments, save those for
516 appendices on readline and cmd history (which are in other source
519 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
521 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
522 chapter 9; (2) documented 'break' command's menu mode for
523 overloaded names, in response to hgs problem report C++ p-31
525 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
527 * doc/gdb.texinfo: (1) better introductory example; (2) more
528 consistent use of @code, @samp, @file, @kbd throughout; small
529 cleanups to first three nodes; (3) new "Contributors" node;
530 (4) Appendix, Renamed Commands; (5) divert specialized startup
531 instructions to "Targets" chapter for generic manuals, while
532 leaving them up front for manuals specific to specialized
533 environments; (6) apply fixes from RMS comments through chapter 4.
535 * pretex.m4: modify explanatory text slightly (and redefine
536 "regexp") to keep GNU m4 from complaining. (It still crashes
537 later, but one step at a time...)

541 * readline/readline.c (update_line): Avoid dereferencing a pointer
542 before comparing it to its bounds. Saber caught this.

549 stuff for config manual) here where it counts; updated
550 to use new subdir structure (gdb/doc/).
552 * Makefile: generated from above via
556 * gdbint.texinfo: added instructions on generating gdb.info* files
557 locally for release. These are ordinary info
558 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
559 Makefile)---but due to use of texinfo 2, can't count on makeinfo
560 to generate these, so we distribute them already formatted.
562 * gdb.texinfo: included full Info node and menu crud (as generated
563 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
565 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
566 put in comments-for-future gdb.info target (one day makeinfo will
569 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
571 * gdb.texinfo: Updated to include new or old undocumented
572 commands, at least the following (perhaps some others I forgot to
573 record): info f, info float, info path, info program, info s, info
574 set, info source, info terminal, info types, info user, set/show
576 Also covered all recent GDB command renames for v4.
578 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
580 * mipsread.c: Rather than keeping count of how many symtabs
581 and psymtabs we have, for sorting purposes, count them when
582 we need to sort. This fixes bug in rereading of symbol tables.
584 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)

601 symtab.h, target.c, target.h: Lint.
602 * core.c: setup and select frame after reading shared libs,
603 else reading shared libs will clobber them. Lint.
604 * utils.c (error): Force out any buffered wrap text.
606 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
608 * remote.c: Remove decls of memory_insert_breakpoint
609 and memory_remove_breakpoint, no longer used. (Suggestion of
612 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
613 to make it easier to interface to "configure"'d libraries.
615 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
617 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
618 aliases for set/show print.

1009 before returning locals or slocals.
1011 * i386-tdep.c (i386_follow_jump): Do not add data16 to pos in
1012 call to codestream_seek; add one to pos if (and only if)
1013 we are dealing with a jump with data16 == 1 (i.e. 0x66, 0xe9).
1015 Mon Apr 15 12:04:32 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
1017 * valops.c (call_function_by_hand): Put dummy1 in target order

1043 tm-sun3.h: Define TARGET_SUN3.
1045 * utils.c: Use CPLUS_MARKER not '$'.
1047 * cplus-dem.c: Use CPLUS_MARKER not '$'. If CPLUS_MARKER isn't
1048 defined, define it to '$'.
1050 * arm-opcode.h: New file (same contents as before; it had
1051 just been left out of the distribution for a long time).
1053 * tm-68k.h: Put declaration of ext_format_68881 outside the macros.
1055 * main.c: New HAVE_SIGSETMASK #ifdefs.

1121 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
1122 New function to give correct error message.
1124 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
1126 * target.h: Add to_doc and target_preopen.
1127 target.c: Add target_preopen and target_command.
1129 (add_target): Call add_cmd and mess with targetlist->doc.
1130 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
1131 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
1132 Call target_preopen from open routine.
1134 * main.c: Rename editing_info to show_commands.

1151 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
1153 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
1154 * symfile.c (clear_symtab_users_once, cashier_psymtab,
1155 free_named_symtabs): Move these routines from symmisc.c.
1156 * symmisc.c (same): same.
1157 (free_symtab): Make non-static.
1158 * symtab.h (free_symtab): Declare as exported void fn now.
1159 * dbxread.c (end_symtab, end_psymtab): Change comments.
1160 (initialize_dbxread): Call dbx_new_init() in case the first
1161 command is add-symbols.
1162 * target.c (dummy_target): Permit add_syms_addr_command.
1164 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1166 Permit symbols to be superseded when new symbol files have
1167 been read in, particularly for VxWorks.
1169 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
1170 to the main file, as well as to include files. Also, put global
1171 functions into the global psymtab, to make "i fun" work.
1172 (end_psymtab): Free named symtabs and psymtabs for a file, once a
1173 new psymtab for it has been read.
1174 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
1175 a file, once a new symtab has been read for it.
1176 * mipsread.c: FIXME. We need to do the same for MIPS, but it
1177 looks harder to determine the top-level block before it's been
1178 queued to the psymtab list.
1180 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
1181 If we have wiped out any old symbol tables, clean up at end of
1183 (symbol_file_command): Don't reference symfile_fns if it's zero.
1185 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
1186 defines for the blocks of a blockvector that contain global and
1187 file-static symbols and the first of the smaller scope contours.
1188 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
1189 decode_line_1, make_symbol_completion_list): Use the above.
1190 * coffread.c (end_symtab, patch_opaque_types): Ditto.
1191 * dbxread.c (end_symtab): Ditto.
1192 * expread.y (block): Ditto.
1193 * mipsread.c (throughout): Ditto.
1194 * symmisc.c (free_named_symtabs): Ditto.
1196 * symtab.c (list_symbols): Process the first symbol of the
1197 static psymbols list.
1198 (types_info): Restore this function from its untimely #if 0.
1199 It's not perfect, but it is better than nothing.
1200 (_initialize_symtab): Restore "info types".
1202 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1204 * m68k-stub.c: Remote stub for 680x0's, created from
1205 rem-m68k.shar (which is removed).
1206 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
1207 Remove RCS log stuff now that we use CVS and it blows our diffs.
1209 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1211 * symmisc.c (free_named_symtab): Make it work, in its current
1212 kludgy fashion. Change result to indicate if we blew away bkpts.
1213 * dbxread.c (end_symtab): Accumulate result from
1214 free_named_symtab and print warning if we blew user's state.
1215 * symfile.h: free_named_symtab now returns an int.
1217 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1219 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
1220 is the first symbol read, even if not mainline.
1221 (dbx_psymtab_to_symtab): symfile might be zero, cope.
1222 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1223 (set_section_command): New command ("section xxx yyy" -- should
1224 be renamed to "set section xxx yyy" FIXME) which sets the
1225 base address of a section of the exec file, overriding the
1226 virtual address that BFD reports.
1228 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1230 * exec.c: Add add_syms_addr_command to exec_ops, so you can
1231 load symbols at any address while examining an exec file.
1233 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1235 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1236 for printing the float info is host-dependent, not
1237 target-dependent. FIXME.
1238 * i386-pinsn.c: Move #includes to top, remove useless ones.
1239 * i386-tdep.c: Don't bother including <.../reg.h> since we
1240 don't use it (and it doesn't exist on host systems).
1242 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1243 Convert negative numbers properly.
1244 (ieee_test): Make numbers really random; fix format arg.
1246 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1247 * core.c (core_detach): Unpush core_ops, which might not be on
1248 top. We used to just pop the top, which broke things. Don't
1249 need dont_repeat() any more.
1250 (core_file_command): Psst! Don't repeat it.
1251 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1252 * expprint.c (print_subexp): Avoid switch fallthru on
1253 BINOP_ASSIGN_MODIFY, so we can print += and such.
1254 * frame.h: Fix typo.
1255 * inflow.c (kill_command): After killing inferior, print our
1256 current frame in the core file, if we have one.
1257 (generic_mourn_inferior): When inferior dies, either select
1258 the current frame (in the new target, e.g. core file), or
1259 set both the current and selected frames to NULL.
1261 Changes from Peter Schauer.
1263 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1265 * Make all file names fit in 14 characters (sigh and damn!):
1266 mv hp300hpux-xdep.c hp300ux-xdep.c
1267 mv symmetry-xdep.c symm-xdep.c
1268 mv symmetry-tdep.c symm-tdep.c
1269 mv convex-opcode.h convx-opcode.h
1270 mv tm-vxworks960.h tm-vx960.h
1271 mv tm-vxworks68.h tm-vx68.h
1272 mv Makefile.srcdir Makefile.sdir
1273 mv gdb-int.texinfo gdbint.texinfo
1274 mv remote-sa.m68k.shar rem-m68k.shar
1275 mv remote-multi.shar rem-multi.shar
1276 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1277 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1278 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1281 * command.c (user_info_1, user_info): New command for listing
1282 the user-defined commands.
1284 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1286 * dbxread.c (really_free_pendings): Clear file_symbols
1287 and global_symbols after freeing them; otherwise, running
1288 this function twice (if it appears twice on the cleanup
1289 chain), we try to free things twice.
1291 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1292 based on text_addr (the address of text in core), not on addr (the
1293 offset between text in the .o file and in core). This change
1294 is from Peter Schauer.
1296 * main.c: Define ALL_CLEANUPS as a cast of zero.
1297 (return_to_top_level): Use it.
1298 (main): Do all cleanups after each command run as part
1299 of the gdb startup sequence. Also do all cleanups before
1300 entering the command loop, and every time we exit the command
1301 loop and reenter. Before, the cleanups from the startup sequence
1302 were being left undone until the first error!
1303 (command_loop): Rename do_nothing cleanup to command_loop_marker
1304 so we can see it easily when examining the cleanup chain.
1305 (init_signals): Add another do_nothing for signal handling.
1306 (quit_command): Only try to kill target if it has execution.
1307 Problems in the target stack got us into a state where
1308 inferior_pid was nonzero but none of the targets had execution.
1309 In this state you couldn't exit gdb.
1311 * dbxread.c: Two changes from Peter Schauer.
1312 (echo_command): Fflush output after an echo command.
1313 (show_history): Pass all args to cmd_show_list.
1315 * utils.c (init_malloc): Call mtrace to turn on tracing
1316 if the environment variable MALLOC_TRACE is set to a file name.
1317 * mtrace.c: Add source file which provides a log of every malloc,
1318 free, and realloc to a trace file.
1319 * mtrace.awk: Add source file which analyzes the trace file.
1320 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1321 (VERSION): Roll to 3.94.3.
1323 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1324 (check_duplicates): Don't bother with watchpoints.
1325 (set_raw_breakpoint): Comment about danger of this routine.
1326 (watch_command): Parse and eval all args before calling
1329 * solib.c (find_solib): Avoid error in referencing memory to
1330 see if any more shared libraries have been added. This is
1331 particularly useful if the target has terminated. Bug reported
1334 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1335 in bringing up 3.94.2 on the Sun-3.
1337 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1338 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1339 expression (in scope) before reenabling watchpoint.
1340 * signame.c (init_sigs): Add missing declaration of i, fix
1341 sys_siglist declaration.
1342 * source.c (list_command): Fixed range computation to use
1344 * stack.c (backtrace_command): Do not allow command if target has
1345 no stack, print informative error message.
1346 * target.c (target_command): Do not write into command line
1347 because this fails if the target command is used in a user defined
1348 command. [This change was enhanced by gnu to support any-
1349 unique-prefix matching on target names.]
1350 * valops.c (value_struct_elt): Avoid infinite loop on an
1351 erroneous attempt to print the member of function (try p main.p).
1353 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1355 * expread.y (name_no_typename): Avoid reduce/reduce errors
1356 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1357 Since the GDB parser really doesn't use name_no_typename in a
1358 name-only context, the parser can't tell the diff between
1359 names and numbers here. Avoid allowing a name_no_typename
1360 to be a NAME_OR_*INT to resolve the conflict.
1362 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1364 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1366 * valprint.c (val_print_fields): bitfield printing didn't handle
1367 byte order. Indirect through a few more fns to cope.
1369 * values.c (modify_field): also cope with byte order.
1371 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1373 Cleanup for release 3.94.2:
1375 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1376 include files. Roll version to 3.94.2.
1378 * coffread.c (init_stringtab): Read length into unsigned char
1379 array before swapping; don't assume 32-bit longs.
1381 * target.c (target_info): Don't bother with get_sym_file, just use
1382 the symfile global variable.
1383 * symtab.h, symfile.c (get_sym_file): Delete it.
1385 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1386 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1387 (read_type): Replace one more error() with complain().
1389 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1391 * i960-tdep.c: Fix copyright attribution.
1393 * config.gdb: Quote all backquotes in doublequotes. You can
1394 quote me on that. BSD 4.4 shell found this one.
1396 * infptrace.c (throughout): The third argument to ptrace is an
1399 * infrun.c (wait_for_inferior): When program has terminated, we
1400 have to call target_terminal_ours before we pop that target off
1401 the stack (e.g. before a call to target_kill or
1402 target_mourn_inferior). This fixes problem where a program
1403 terminates, then GDB stops for (tty output) and you have to type
1404 "fg" to the shell to resume it. FIXME: This code for what to
1405 do after termination really should be in normal_stop instead.
1407 * gdbcore.h (read_memory_check): Change declaration; it changed
1410 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1411 4.4 prereleases, this avoids a bug in their sgtty compatability
1413 * remote.c: Use terminal.h rather than hand-rolling the same.
1415 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1416 * utils.c (strsave, strstr): Fix arg types.
1417 * valprint.c (val_print): lint
1419 MIPS symbol table support from Per Bothner:
1421 * symfile.c (symtab_fns): Remove initializer table that needs to
1422 be hacked for each new symbol file format supported.
1423 (add_symtab_fns): New function, chains symbol table
1424 handlers into the global list.
1425 (symfile_init): Search this list.
1426 * symfile.h: Add next pointer, declare add_symtab_fns.
1427 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1428 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1430 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1431 symbol *). Thus, we no longer need the hack to trash
1432 pst->filename. Good, since that hack confused code in symfile.c!
1434 (reorder_symtabs, destroy_all_symtabs): Removed static
1435 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1436 Instead, the latter now uses a temporary array (stack-allocated
1437 from an obstack, and then freed).
1439 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1440 haven't been set in the outermost stBlock of a procedure. This was
1441 a problem with f77 binaries on Ultrix 4.?.
1443 (new_symtab, new_symbol, new_type): Continue changing code to use
1444 obstacks more and otherwise conform to dbxread internal style.
1445 Made the free_code of symtabs be free_linetable (as in dbxread)
1446 instead of free_contents. This implies memory leaks when reading
1447 a new symbol table, until the conversion is finished. Did change
1448 (struct symbol) and (struct type) to be allocated on the
1449 symbol_obstack. Blocks and blockvectors are among the things
1452 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1453 tested much, but it solved one problem (reported by Meissner), and
1454 cleans up some other things. The problem happened when an
1455 included file contains actual code (functions) and not just
1456 definitions. The mips coff is a little inconvenient there, since
1457 it may cause a procedure to be mapped to the wrong psymtab.
1459 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1460 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1461 this will need work for the new core paradigm.
1463 Opcode patches from the net:
1465 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1466 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1467 missing altogether - they are added here. From Bruce Bauman.
1468 * mips-opcode.h: The low mask for C0 instructions was too small.
1469 From Garrett Lau. I modified the fix to check the entire 32-bit
1472 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1475 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1477 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1479 * dbxread.c (read_type): Pointer subtraction (value_sub in
1480 valarith.c) sometimes failed because the types of the
1481 pointers being subtracted were not identical.
1482 These differed because dbxread.c was allocating pointer types
1483 using dbx_alloc_type+smash_to_pointer_type instead of
1484 lookup_pointer_type. I failed to find a justification for the
1485 former, so I changed it to use the latter. Similarly, I
1486 replaced smash_to_function_type by lookup_function_type,
1487 and smash_to_reference_type by lookup_reference_type.
1489 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1490 _initialize_mipsread): corresponding changes.
1492 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1494 * source.c (mod_path): Do tilde_expand on each component of the path,
1495 rather than on the (list of) paths as a whole.
1496 (print_source_lines): Set first_line_listed in addition to
1497 current_source_symtab and current_source_line. If the source was
1498 not findable, after a "dir" command to fix the problem,
1499 a "list" would get the wrong lines.
1501 While I was there... (gnu):
1503 * dbxread.c (read_type): Change error to complaint.
1505 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1507 First attempt at detailed understanding of symbol table memory alloc.
1509 * dbxread.c (dbx_symfile_read): Free our string table if we
1510 aren't the mainline. Free the "info" struct since we're done with
1512 (init_psymbol_list): Free any previously allocated psymbol lists.
1513 (): FIXME: Should realloc-down the psymbol lists when done reading
1514 the main symbol file?
1516 * symmisc.c (free_symtab): Free fullname field too.
1518 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1519 (REGISTER_ADDR): Make result type unsigned int.
1521 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1522 define REGEX must also define REGEX1 (its dependency).
1524 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1526 * tconfig/i960: No longer works, points you at vxworks960 or

1531 * Makefile.dist: Remove all trace of xgdb.
1533 * breakpoint.c (breakpoint_1): Pass demangle arg to
1534 print_address_symbolic.
1535 (clear_breakpoints): Remove unused function.
1536 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1537 (breakpoint_re_set): Use catch_errors to do them all anyway.
1539 * gdb-int.texinfo (Host versus Target): Add section on what is
1540 a "host" feature versus what is a "target" feature.
1542 * infcmd.c (path_command, path_info): Handle the PATH variable
1543 (object search path) as conveniently as the source search path.
1544 * environ.c (set_in_environ): Set some vars in GDB's environment,
1545 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1546 * source.c (mod_path): New function, from guts of
1547 directory_command, modifies a path. Used by path_command.
1548 (directory_command): Call it.
1549 * defs.h (strsave): Declare.

1552 (printchar): Use it.
1553 (strsave): Provide this handy helper routine.
1554 (set_width_command): Rename set_screen_width_command.
1555 (_initialize_utils): "set screen-width" => "set width";
1556 "set screen-height" => "set height"; add sevenbit-strings.
1558 * infcmd.c (do_registers_info): Print floating point registers
1559 in raw hex as well as float format, regardless of whether it is
1560 a "virtual" convertible register.
1561 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1562 regs as a double, just in case it's being used that way.
1563 * values.c (unpack_long): Comment on array/function coercion.
1564 (unpack_double): Argument is in target byte order now. For
1565 integer arguments, just call unpack_long and float the result.
1566 * m68k-tdep.c: include defs.h for "const" handling.
1567 * remote-nindy.c: Use ieee-float stuff.
1568 (nindy_fetch_registers): Unpack double regs to host double, then
1570 (nindy_store_registers): Pack extendeds to host double, flip
1571 around by misusing unpack_double, send as target double.
1573 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1574 zero, as when stopped at the first instruction of a process.
1576 * blockframe.c: Fix filename in comment (param.h => tm.h).
1577 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1578 * tm-68k.h: Fix typos.
1580 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1582 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1584 * coredep.c (fetch_core_registers): Pass end-address of register
1585 section to register_addr as expected. Don't call supply_register
1586 if we'd just pass it garbage.
1588 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1590 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1592 * target.c (push_target, target_info): Cast enums to int for < or

1596 even if we can't print it.
1598 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1600 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1602 Clean up IEEE floating point support.
1604 * ieee-float.h: New file.

1614 * m68k-tdep.c: Define ext_format_68881.
1615 * sparc-tdep.c: Define ext_format_sparc, though unused.
1616 * Makefile.dist (HFILES): Add ieee-float.h.
1617 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT

1623 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1624 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1625 * tconfig/nindy960: Remove reference to coffstrip.o.
1627 * Makefile.dist: Roll version number to 3.94.1 (not yet final).

1632 * dbxread.c: Remove static symfile_bfd.
1633 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1635 * inftarg.c (child_detach): Pop the child_ops vector if the
1636 detach is successful.
1637 * remote-nindy.c (nindy_create_inferior): Don't push a new
1638 nindy_ops since nindy uses the same one for execution and memory
1640 * core.c (core_ops): Use child_attach and child_create_inferior
1641 rather than default attach and create_inferior functions.
1643 Handle floating point registers in core files.
1645 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1646 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1647 This version untested since BFD doesn't yet support sun3 core
1649 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1650 conventions. Fix comments and style. This version has not
1651 been compiled yet, since we have no HP inhouse.
1652 * core.c (get_core_registers): Look for two sections, ".reg"
1653 and ".reg2", and pass both to fetch_core_registers sequentially.
1655 Revise directory path yet again.
1657 * source.c (forget_cached_source_info): Not static any more.
1658 (init_source_path): New default source path is "$cdir:$cwd".
1659 (dir_command): Handle variable arguments ($cdir, $cwd).
1660 (source_info): Print "Compilation directory" rather than
1661 "Originally compiled in" to remind people of $cdir.
1662 (openp): If the path contains $cwd, use current directory.
1663 (open_source_file): If compilation directory is known, replace
1664 first $cdir in path with the compilation directory.
1665 (print_source_lines): Even if we can't print the lines, set the
1666 current symtab and line for future commands like "info source" or
1667 "breakpoint". Also, error message now contains the file name,
1668 line number, and file access error message.
1669 (_initialize_source): Fix help text to describe changes.
1670 * main.c (cd_command): Forget cached source info when we chdir.
1671 * utils.c (strstr): Add simple implementation.

1675 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1676 Byte-swap COFF symbol tables if necessary when reading them in.
1677 Use complain() to replace error message in one spot. Needs
1678 corresponding change in bfd/coff-code.h to make some symbol
1679 swapping routines non-static.
1681 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)

1696 <rpc/rpc.h> and <rpc/types.h>.
1698 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1700 * i960-tdep.c (examine_prologue): Add new argument limit,
1701 which stops the scan at the end of the prologue, or at the PC.
1702 This fixes a problem where it walks down into the code for the
1703 user's statements if that code looks like function prologues.
1704 Mark Fox and I have been bouncing this code back and forth, making
1705 small changes to it. Callers changed to match.
1707 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1709 Cleanup for gdb-3.94 release final:
1711 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1712 the .c files from vx-share and nindy-share, from the various
1713 macros, since they are not found via ALLDEPFILES.
1714 (SFILES): Add tm-i960.h.
1715 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1716 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files

1723 * am29k-tdep.c: Add contribution line.
1724 (examine_prologue): Cache information about function prologues in
1725 the misc-function-vector to avoid lots of references over the
1726 serial line while examining instructions.
1728 * core.c (core_close): New function made from cleanup_core.
1730 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1731 remote-vx.c, remote.c, target.c, target.h,
1732 Update target_ops vector to add attach, close, and load entries.
1733 Use add_syms_addr_command, not add_file_addr_command, for
1734 add_file. Break out close routine from existing code.
1736 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1737 they are in an obstack.
1738 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1740 (define_symbol): Add symbol type parameter; change callers;
1741 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1742 it to influence the symbol class on the i960.
1743 (define_symbol): Swap LOC_CONST's into target byte order.
1745 * exec.c (exec_close): New function.
1746 (exec_file_command): Call it.
1748 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1749 Fix byte order of frame pointer.
1750 (read_var_value): Result of 0 if var's value can't be found,
1751 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1752 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1753 (locate_var_value): Use read_var_value and use its lazy address
1754 as the location of the var's value. Lint.
1756 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1759 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1760 obsolete Intel versions in favor of vxgdb versions.
1761 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1762 code dealing with byte order of values, which Intel did in host byte
1763 order rather than gdb-4's target byte order.
1764 (i960_frame_chain_valid): Move to nindy-tdep.c.
1765 (examine_prologue, skip_prologue, frame_find_saved_regs,
1766 frame_args_address, leafproc_return, saved_pc_after_call,

1772 saved value over the current value in the topmost frame.
1773 Cache result in the frame info to avoid performance hair in
1775 (print_fault): Add gdb960 code for printing faults.
1776 (_initialize_i960): Actually call check_host.
1778 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):

1784 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1785 (child_attach): Rename from child_open.
1786 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1787 don't confuse it with a zero step_resume_break_address.
1789 * inftarg.c (child_detach): Eliminate inferior_pid test.
1790 (child_files_info): Clean up message a bit.
1791 (child_ops): Use child_attach, not child_open, to attach.
1793 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1794 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1795 findvar.c to here, since it depends on the contents of the
1796 shadow_contents of breakpoints, but keep if #if 0 since it is
1799 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1802 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1803 (ptype_command, display_command): Eliminate have_inferior_p and
1804 have_core_file_p in favor of target_has_stack or
1805 target_has_execution.
1806 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1807 code for actually finding the values of arguments, though we still
1808 keep track of the maximum stack offset for use in printing unnamed
1809 arguments. Handle missing FRAME_ARGS_ADDRESS.
1811 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1812 (struct nindy_regs): Define registers passed to/from nindy.
1813 (nindy_fetch_registers, nindy_store-registers): Translate between
1814 nindy and GDB formats for the registers.
1815 (dcache_init): Statically allocate the cache, since it was being
1816 allocated by a malloc that was never freed anyway.
1817 (nindy_create_inferior): Error, not core dump, if no exec file.
1818 (nindy_before_main_loop): Use target_load, not target_add_file.
1820 * remote-vx.c (net_load): Specify large timeout for load
1821 requests. Allow user to break out with INTERRUPT.
1822 (net_break): Remove useless code, clean up. Change callers.
1823 (parse-args, skip_white_space, find_white_space): Clean up arg
1824 parsing to cope with quoted strings.
1825 (net_wait, net_quit): Never call error, just return status.
1826 (vx_read_register, vx_write_register): Cleanup status checking.
1827 #ifdef the code based on which CPU we are using (960 or 68k),
1828 FIXME, this should be completely general but it isn't yet.
1829 (vx_xfer_memory, vx_resume): Cleanup status checking.
1830 (vx_run_files_info): Improve message.
1831 (vx_load_command): Renamed from vx_add_file_command. Allow load
1833 (net_ptrace): Remove unused routine.
1834 (vx_wait): Adopt code from vxgdb960 to cope with broken
1835 connections to target machine and prompt to disconnect. Remove
1836 debug printouts. Map some EVENT_'s to SIGnals.
1837 (add_symbol_stub, vx_open): Print names of object files we found,
1838 and "ok" if we read their symbols OK. Clarify output in general.
1839 (vx_attach, vx_detach, vx_kill): Add these commands.
1840 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1841 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1842 "info files" output, and create_inferior, since we already have
1845 * stack.c (frame_info): Replace Frame_unknown with 0.
1846 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1847 (return_command): Pop until the PC matches as well as the FP,
1848 so it works even if the FP is shared with another function,
1849 as in "frameless" or "leaf" procedures.
1851 * symfile.c (load_command): renamed from add_file_target_command.
1852 (add_syms_addr_command): renamed from add_file_addr_command.
1853 (add_syms_command): Stub to call target_add_syms.
1854 (_initialize_symfile): Change command names and descriptions,
1855 add-file => add-syms, and load from alias to its own command.
1857 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1858 maybe_kill_then_create_inferior): Default for attempts to start
1859 a process, if one is already running, is to ask about killing
1860 it and retry if yes.
1861 (upstack_create_inferior): #if-0 it, strata obsolete it.
1862 (push_target, unpush_target, pop_target): to_close() a target
1863 before unstacking it.
1864 (target_info): Renamed from target_files_info.
1865 (_initialize_targets): Rename "i files" as "i target", accessible
1868 * target.h: Improve comments about the target_ vectored routines.
1870 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.

1873 (SKIP_PROLOGUE): No longer a no-op.
1874 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1875 (*_REGNUM): Sort register numbers.
1876 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1877 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1878 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1879 are now 10 byte extendeds, not 8 byte doubles.
1880 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1881 for nindy versus vxworks targets. FIXME, this should possibly go
1882 in the target vector.
1883 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1884 frame_saved_regs and arg pointer with each frame.
1885 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1886 (FRAME_ARGS_ADDRESS): Use cached result.
1887 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1888 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1889 (PRINT_RAMDON_SIGNAL): Call print_fault.
1890 (POP_FRAME): Now works.
1892 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1893 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1894 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1895 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1898 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1899 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1901 * valarith.c (value_subscripted_rvalue): Avoid handling
1902 floats and doubles specially; it gave alignment errors. Lint.
1904 * valops.c (value_of_variable, value_of_this): Error if unknown
1907 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1908 to avoid alignment problems.
1909 (value_print): Handle unknown value address.
1910 (cplus_val_print): Two args are ignored; remove them. Change caller.
1911 (val_print): Use unpack_long rather than pointer-deref.
1914 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1915 to avoid alignment problems.
1916 (value_being_returned): Error if return value unknown.
1917 (set_return_value): Add bogosity warning, FIXME. *
1919 * TODO: A woman's work is never done.
1921 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1922 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1923 Add ieee-float.o to OBS.
1924 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1925 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1926 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1928 Changes to generalize the VxWorks RPC protocol slightly, to handle
1929 i960 as well as 68000.
1931 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1932 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1933 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1934 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1935 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1936 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1937 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1938 so they will move in target byte order rather than network
1939 byte order (happens to be the same).
1941 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1943 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1945 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1948 Add contribution lines to various files, showing where they
1951 * breakpoint.c (break_insn, check_break_insn_size,
1952 read_memory_nobpt): Remove to mem-break.c.
1954 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1957 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1958 entry has bad register number. This change is not
1959 tested in this release, FIXME.
1961 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1964 * value.h: Force value's contents field to be aligned to hold
1965 at least a double or a long long (if supported). This avoids
1966 doing bcopy's in and out of the contents field.
1968 (step_1): Avoid coredump under obscure circumstances when we
1971 * symtab.h (misc_info): Add field to misc function vector for
1972 any kind of cached information the target code desires. AMD
1973 29000 uses this to avoid repeating examine_function_prologue's.
1975 * coffread.c: Lint. Remove static symfile, read_section_header.
1976 core.c (have_core_file_p): Lint: remove.
1977 expprint.c (print_subexp): Lint.
1978 infptrace.c, valops.c, valprint.c: lint.
1980 Roll in changes from vxgdb-5.0.1:
1982 * symtab.h: Comment byte order of each address class. Add
1983 LOC_LOCAL_ARG for frame-relative args (960).
1984 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1985 symtab.c, symmisc.c: ditto.
1987 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1989 * remote.c (remote_resume): Error if resume with a signal.
1991 * symfile.c (prim_record_misc_function): Clear misc_info.
1992 (fill_in_vptr_fieldno): Check stub type of arg.
1994 * valops.c (value_cast): Avoid looking up names of types whose
1995 name we don't know, to prevent coredump. Sun CC produces typedef
1996 rtx and the name of *rtx is zero...
1998 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2000 Roll in changes from final AMD 29000 port (Tiemann).
2002 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
2003 for ../include/a.out.encap.h. This might not work now that BFD
2004 is separately compiled. Instead, BFD support for encap will have
2005 to translate machine type 29k into the right COFF_MAGIC.
2007 * infcmd.c: Remove references to inferior_pid that aren't used
2008 in actual ptrace calls; use target_has_execution, etc.
2009 (have_inferior_p): Remove function.
2010 (program_info): Print target info rather than "process number";
2011 avoid gratuitous messages unless from_tty.
2012 (run_stack_dummy, finish_command): Set proceed_to_finish.
2013 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
2014 main.c: Lint. Lose have_inferior_p().
2015 inferior.h (have_inferior_p): Remove, lint.
2016 (proceed_to_finish): Add flag to ask that all regs be saved
2017 by normal_stop, for the few commands that need it, speeding up
2018 serial I/O. Add comments to stop_registers.
2020 * remote-eb.c: Remove newline from breakpoint message we grep
2021 for. Never time out when running the user program.
2025 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2027 Roll in changes from vxgdb-5.0.1:
2029 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
2030 symbol in its raw form, we are processing an unlinked ".o" file.
2031 See if the target environment has assigned it an address, using
2032 target_lookup_symbol (VxWorks does), and enter it into the symtab
2035 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
2036 68k versions for a simpler version that assumes zero FP at bottom.
2037 Fixes bug of truncated stack reports.
2039 * target.h (target_lookup_symbol): Define this routine's args
2040 and result, finally.
2042 * target.c (nosymbol): Default routine for target_lookup_symbol.
2043 (target_default): Default lookup_symbol and call_function too.
2044 (files_info): Only print has_all_memory warning if a non-dummy
2047 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
2048 vx_convert_from_virtual): If target does not have floating point,
2049 zero register "values", and avoid doing cross-net conversions.
2050 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
2051 (vx_open): Rearrange code that attaches to target and reads
2052 symbols for all loaded modules, to work if some of the modules
2053 are not accessible. Add symbol_stub() and add_symbol_stub()
2054 as callbacks from catch_errors(). Allow connect attempt to be
2055 interrupted painlessly with ^C (FIXME, there are still some bugs
2056 if the interrupt happens during symbol reading.). Print
2057 final message with puts_filtered, since symbol messages are
2062 * main.c (catch_errors): Only print errstring if non-null.
2063 (command_loop): Avoid an ioctl per command to test ISATTY.
2065 * remote-vx.c (net_load): make static; avoid sophomoric msg.
2066 (vx_xfer_memory): Return correct result!
2067 (vx_files_info): Indicate whether target has float or not.
2068 (vx_lookup_symbol): Complain, not error, if target gone.
2069 (vx_open): Print "Connected" msg before disabling immediate-quit.
2070 [FIXME: lookup_symbol and vx_open changes need testing.]
2072 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
2073 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
2074 contributor lines and update copyrights to 1991.
2076 Changes from an attempted H-PUX host port:
2078 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
2079 defines PT_ATTACH and PT_DETACH but not PT_KILL.
2080 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
2081 * remote-vx.c: include <sys/time.h> for HPUX.
2082 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
2083 "core_file_command" routine to BFD regime. May not work yet.
2085 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
2087 * xgdb.c: Replace X10 version with some VJ version.
2088 (FIXME: Its copyright assignment is not on record.)
2089 * xgdb.c: Update include files to X11R4 (Xaw crud).
2090 (xgdb_display_source, create_text_widget): fix call to
2091 get_filename_and_charpos. Rewack source window stuff for X11R4
2092 (gleaned from include files, and "nm's" of binary libraries, since
2093 I had no doc available).
2094 (append_selection, append_selection_word): Disable with FIXME
2095 since R4 changed interface here.
2096 (create_buttons): Add back the old set of buttons.
2097 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
2099 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
2100 Roll VERSION to 3.94 (not yet final though).
2102 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2104 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
2105 obstack_int_grow, obstack_int_grow_fast): Eliminate
2106 cast on left of assignment, which gives MIPS cc fits and is
2109 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
2110 F_ALIAS. Use printf, not fprintf, when not passing a file
2112 (compare_opcodes): Check that identical instructions have
2113 identical opcodes, complain otherwise.
2115 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
2116 was reported by Roland McGrath.
2117 (unimp): Only match if exactly zero instruction. (Roland)
2118 (branches and traps): Generate all variations of these
2119 instructions with macros, based on a single call that defines
2120 each condition name and its binary representation.
2121 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
2123 * valprint.c (val_print_fields): Take, and use, format parameter.
2124 This means that "p/x struct" again prints the elements in the
2125 desired format. Changed callers.
2127 * stack.c (frame_info): Use filtered output, and indicate wrap
2128 points. Remove kludgy formatting designed to avoid line wrap.
2130 * utils.c (wrap_here): If the line is already full (because
2131 we had printed a long indent or long wrapped string), do an
2132 immediate newline-and-indent.
2134 * m68k-pinsn.c (print_insn_arg): Bugfix from
2135 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
2136 instruction is incorrectly disassembled as bkpt #8.
2138 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
2139 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
2140 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
2141 and then will dump core (sometimes). I traced it back to an
2142 uninitialized symfile_name in psymtab_to_symtab.
2143 (const_vol_complaint): Add quotes to message.
2144 (define_symbol): Only believe line number if gcc_compiled.
2145 Avoid allocating symbol if we will not return it.
2147 Add target strata support so that newly established targets go
2148 into their right place in the target stack (e.g. a new exec file
2149 doesn't wipe out the ability to access the running process).
2151 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2152 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2153 and initialize it properly in all the targets.
2155 * target.h: Document strata. Change return type of push_target.
2157 * target.c (nomemory): new function for dummy memory access.
2158 (tcomplain): Rename complain, now also used in symfile.c.
2159 (push_target): Push targets within strata. New return value shows
2160 whether new target is on top of stack or not. Always keep dummy
2162 (target_files_info): Ignore dummy target.
2164 * core.c (core_open): Warn user, and skip accessing file, if the
2165 core target is not the topmost target in the stack.
2166 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2169 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2170 target_ops, it doesn't belong there since we have no regs there.
2171 Change name of target from machine => memory to clarify.
2173 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2175 * Freeze version 3.93 for release.
2177 * Makefile.dist: Handle vx-share and nindy-share subdirs
2178 properly when building gdb.tar.Z.
2180 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2181 printed in various places, so I could change just one copy.
2183 * dbxread.c, coffread.c: Change references to bfd->iostream
2184 to cast to FILE *, now that BFD avoids needing types defined
2185 in other header files.
2187 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2189 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2190 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2191 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2192 (actually gcc -Wall).
2194 * dbxread.c: Remove first_global_sym, last_global_sym, since
2195 they are never referenced.
2197 * defs.h (baud_rate): Declare.
2198 main.c: Define it, and add the -b option to set it.
2200 * gdb-int.texinfo: Add text on how to define a new host or target
2201 architecture, prompted by Per Bothner's questions about MIPS
2204 * gdb.texinfo: Document "complaints". Change doc of -q since
2205 gdb no longer prints the copyright and blurb if you specify a file
2206 name to be debugged (just like Emacs). Add doc for Nindy-specific
2207 command line flags for specifying target serial port and such.
2208 Update copyright to 1991.
2210 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2211 has taken over for us the job of ripping up executable files. The
2212 crud caused Per Bothner's port to not compile.
2214 * infrun.c (normal_stop): Avoid printing "Program exited
2215 normally" if we are in batch mode. This allows a GDB which
2216 executes a program on a target system, to behave like a Unix
2217 command (input from stdin, output to stdout, no extraneous
2220 * main.c (main): Allow additional machine-dependent command line
2221 options to be specified with the ADDITIONAL_OPTIONS,
2222 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2223 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2224 processing to occur just before the main loop with
2225 BEFORE_MAIN_LOOP_HOOK.
2226 (main): If a "core file" argument is specified, and it is not a
2227 core file, try it as a process ID to attach.
2228 (symbol_completion_function): Attempt to cope with
2229 "show screen-" TAB, not very successfully. This needs more work,
2231 (batch_file): New function, returns whether we are reading
2232 commands from an interactive tty on stdin, or from somewhere else.
2233 Called by normal_stop since it doesn't get from_tty passed down
2234 to it like many commands do.
2236 * remote-nindy.c: Handle command line options for nindy
2238 (nindy_before_main_loop): Prompt user for tty name if they
2239 don't specify it before getting to the interactive command loop.
2241 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2242 and -r command line options. Also add hook before main loop
2243 to make it easy to specify a tty.
2245 * TODO: More things to do, one done.
2247 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2249 * dbxread.c: Make complaint() calls pass pointer, not struct.
2250 Add complaints about badly formatted C++ type information
2251 (const/volatile indicator, and parse errors resulting in
2252 error_type). Fix C++ virtual member fn comment.
2253 (read_struct_type): Avoid bumping pointer if we got a parse
2254 error; this prevents our walking beyond the end of a string.
2255 Terminate loop on null char as well as semicolon.
2256 (process_one_symbol): Fix the LBRAC fix so that it uses the
2257 last previous SLINE, FUN, or SO record's PC address. C++ debug
2258 symbols did not have SLINE records in a useful order compared
2259 to the LBRAC records.
2260 (define_symbol): Handle "catch" records.
2262 * symtab.c (check_stub_type): Added new complain
2263 `stub_noname_complain' and added a consistency check to
2264 keep the debugger from crashing when finishing from an
2265 exception frame. A real fix will be needed later.
2267 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2269 * infcmd.c (attach_command): Make global.
2271 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2272 but make them easy to comment out. Perhaps later they should
2273 be enabled by what CPU you configure for? FIXME.
2274 (VERSION): Roll to 3.93.
2275 (pinsn.o): Remove rule for obsolete file.
2276 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2278 Run down a problem that manifested by printing the wrong function
2279 name in stack traces of read_ofile_symtab. Turned out that the
2280 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2281 the LBRAC symbol with an address in the *data* segment, which
2282 blew our binary search through the blocks.
2284 * dbxread.c: Use the complain() facility consistently to bitch
2285 about problems in the symbol file we are reading.
2286 (finish_block): Add code to check the nesting of the blocks;
2287 complain and Procrust them to fit if wrong.
2288 (make_blockvector): Check the order of the blocks, complain
2289 [but don't cope] if wrong.
2290 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2291 symbols to be sure their PC value is greater than the last SLINE
2292 (line number) symbol we've seen, complaining and adopting the
2293 SLINE PC value if wrong.
2295 * symfile.h (struct complaint, complaint_root, complain,
2296 clear_complaints): Add.
2297 * symfile.c (complain, complaint_root, clear_complaints): Add
2298 facility to deal with non-fatal complaints and to regularize their
2300 (symbol_file_add): Clear complaint counters to allow new complaints.
2301 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2303 * dbxread.c (dbx_symfile_read): Remember the address and size
2304 of the string table for the main symbol file, so we won't read it
2306 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2307 to avoid reading the string table yet again. Lint.
2308 (throughout): Improve filtered output, including word wrap.
2309 (read_range_type): Improve Bothner's fix to handle other types too.
2311 * utils.c: Improve line wrap implementation. Handle unlimited
2312 width by making chars_per_line unsigned.
2313 (puts_filtered): New, easy, function.
2315 * defs.h (puts_filtered): add.
2317 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2318 call the identical sort_symtab_syms() in symfile.c instead.
2320 * expread.y: Suggest the `file' command rather than `symbol-file'.
2322 * command.h (enum var_types): Add zinteger for seroable
2324 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2325 nested if's into a switch.
2327 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2328 we did not stop because of a breakpoint (it must have been for
2329 some other reason, like a "stepi"), so don't print anything.
2331 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2332 doesn't include <sys/types.h>, old SunOS's require it for
2335 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2337 A test port of gdb-3.92.6 to the Sony NEWS.
2340 Don't normally link in remote- or vx stuff.
2341 Some of it doesn't compile, and it wastes space for 99% of the users.
2342 Remove reference to no-longer-used HAVE_VPRINTF.
2343 Fixed BFD_DEP typo to BFD_DIR.
2345 Fix cast in arg to bfd_h_getlong.
2346 Make char *prefix be const.
2347 Fix how certain range types are mapped into builtin unsigned int types.
2349 Remove 2 #includes. They cause errors (on Sony, at least),
2350 and aren't needed (they wern't in earlier versions).
2352 print_address_symbolic should never demangle labels
2353 (since it prints *assembler-level* labels).
2355 [This was superseded by the change to printcmd below.]
2358 Add some "volatile" return types to avoid warnings.
2359 If MISSING_VPRINTF add vprintf function and not just macro
2360 (since vprintf is used in printcmd.c).
2362 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2363 (The latter isn't grokked by some PCC-based compilers.)
2365 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2367 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2368 * nindy-share/coffstrip.c
2369 Added some forward declarations (otherwise, gcc complains
2370 about implicit extern redefined as static).
2372 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2374 Changes inspired by Per Bothner:
2375 * printcmd.c (print_address_symbolic): Take additional parameter
2376 specifying whether to demangle.
2377 (print_address): Pass in asm_demangle to control demangling.
2378 (print_address_demangle): New fn, takes explicit arg to control
2380 * utils.c: Add new vars demangle and asm_demangle, and let them
2382 (fputs_demangled): If !demangle, just print the argument.
2383 (fprint_symbol): If !demangle, just print raw symbol.
2384 * valprint.c (val_print): Call print_address_demangle rather than
2385 print_address, to cause demangling to depend on the global
2386 rather than assembler-level demangling setting.
2387 * WHATS.NEW, gdb.texinfo: Document.
2389 * main.c (show_command): Show all settings if no arg.
2390 (initialize_main): Make "info set" the same as naked "show".
2391 * command.c (cmd_show_list): Handle prefix commands in the
2392 list, and print the name of the setting as well as its English
2393 description and value.
2395 Allow gdb functions to specify where a line should wrap if it
2396 exceeds the size of a terminal line. Use it to make the output
2398 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2399 of the right size when screen width changes.
2400 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2401 (wrap_here): New fn, indicates a point in the output where we
2402 should wrap the line rather than just letting it overflow at a
2404 (fputs_filtered): Implement wrapping.
2405 (n_spaces): New fn, returns a pointer to N spaces.
2406 (print_spaces_filtered): Use n_spaces.
2407 * defs.h (n_spaces): Declare.
2408 * stack.c (print_frame_info): Wrap with 4-space indent after
2409 fn name and before filename and line number.
2410 * printcmd.c (print_frame_args): Wrap with 4-space indent
2411 before each argument name is printed.
2412 * valprint.c (value_print): Wrap with no indentation before
2414 (val_print_fields): Wrap with indentation relative to nesting
2415 level before each field name.
2416 (val_print): Wrap with nesting indentation before array elements.
2417 * command.c (do_setshow_command): Avoid extra newlines,
2418 wrap with 4-space indent around values printed, end with period.
2419 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2421 * breakpoint.c (breakpoint_1): Implement addressprint for
2422 "info breakpoints" display. Change file name and line number
2423 format to " at file:nnn" rather than " (file line nnn)".
2424 * gdb.texinfo: Document.
2427 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2429 Frozen for gdb-3.92.6 release.
2431 README, WHATS.NEW: Update for 3.92.6 release.
2433 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2434 coffread.o from configs since it is now built by default.
2435 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2436 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2437 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2438 from configs since it is now built by default.
2440 Makefile.dist: Update for release 3.92.6. Handle files that
2441 have been moved to ../include, ../getopt, or ../bfd. Add
2442 saber.suppress and tests directory. Add config.status to
2443 the release (it will say "none").
2445 coredep.c: Minor formatting fixes.
2447 These changes were made in early December but only checked in now:
2448 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2449 nindy-share/nindy.c: lint
2450 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2451 register values coming back from the target; we store values
2452 in target byte order everywhere.
2454 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2456 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2458 * valprint.c (cplus_val_print, val_print_fields): New functions,
2459 which print C++ objects. They conspire to avoid printing a
2460 virtual base class more than once, following all the twists and
2461 turns of C++ virtual base rules.
2462 (val_print): Call the above rather than do it by hand.
2464 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2465 symbol file, not for added files like shared libs. This really
2466 needs to be generalized to a timestamp per file.
2468 * core.c (cleanup_core): Avoid coredump if no core file.
2470 * config.gdb: Accept -host or -target in place of +host or
2473 * coffread.c (find_linenos): Avoid desupported BFD interface
2474 to line numbers. We still read them manually rather than using
2475 BFD's "generic" features.
2477 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2479 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2481 * Makefile.dist: Eliminate use of $< in explicit targets.
2483 * readline/Makefile: Use $< rather than $*.c, which does not
2484 include the VPATH in GNU Make.
2486 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2487 copies of tconfig/i960, added for global configuration
2488 compatability. All i960 versions can read both coff and b.out.
2490 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2491 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2494 * TODO: Think of more things to do.
2496 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2498 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2499 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2500 64-bit float conversion.
2502 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2503 equivalent to sun?os4 so global config works.
2505 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2507 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2509 * main.c: Only declare linesize once; declare pagesize not at
2510 all, since it is never used.
2511 (main): Clear newly allocated line before it is used.
2513 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2515 Further stabilization for the Intel 960.
2517 * Makefile.dist: Parameterize the location of the "include"
2518 and "bfd" directories, as well as "getopt". Add symfile.c.
2519 Link in both dbxread and coffread. Fix up "make depend" to
2520 rewack the locations of include, bfd, and getopt in its output.
2522 * README: Document moving include files, improve some of
2525 * coffread.c: Move common code out to symfile.c. Change
2526 symbol_file_command style interface to use new *_symfile_init
2527 and *_symfile_read interface under BFD. Use BFD internal
2528 info to locate line table, symbols, etc.
2530 * core.c (core_fetch_registers): Rename to get_core_registers
2531 to avoid confusion with fetch_core_registers.
2532 (register_addr): Move to coredep.c, which is already machine
2533 dependent. This leaves core.c pretty clean of dependencies.
2535 * coredep.c (register_addr): Accept this routine from core.c.
2537 * dbxread.c: Move common code (with coffread.c, etc) into new
2538 symfile.c. Each psymtab now contains a pointer to the
2539 format-dependent function that knows how to read it in. Make
2541 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2542 (process_one_symbol): Add code to complain about a "compiler bug
2543 we muzzle here", if we actually see it.
2545 * eval.c (evaluate_subexp): Insert missing "break" statements
2546 in code that determines whether a variable is an lvalue in
2547 memory, register, or whatever. I detected this via a compiler
2548 bug in which it *almost* mashed out the whole switch statement.
2550 * gdb-int.texinfo: Add minor sections on configuring gdb for
2551 release, and about the README file.
2553 * infcmd.c (registers_info): Fix formatting somewhat. Still
2554 not as pretty as before, but it handles byte swapping.
2556 * remote-nindy.c: If data cache routines are interrupted while
2557 waiting for the remote end, be sure that any uninitialized cache
2558 blocks are on the free list, not on the valid list!
2560 * symfile.h: Flesh out this header file with all the various
2561 routines and variables that have been merged in from dbxread.c
2562 coffread.c, and symtab.c to symfile.c.
2564 * symfile.c: New file, containing code common to dbxread.c,
2565 coffread.c, and some code from symtab.c. All generic code for
2566 reading symbol files should be in here now.
2567 (unrecord_misc_function): Remove unused function.
2569 * symtab.h: Remove file-reading things to symfile.h.
2571 * symtab.c: Remove file-reading things to symfile.c.
2573 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2574 to decode i960 fault types.
2576 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2577 target.c: Change type of the "resume" function from int to void,
2578 since its result was never used.
2580 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2582 * main.c: Replace "stupid" with "caution"; you now "set caution
2585 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2587 * infcmd.c (do_registers_info): Call val_print to deal with the
2588 byte order of the registers being printed. FIXME, this makes
2589 the formatting of the output uglier.
2591 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2592 defined, call it for signals the debugger doesn't itself use.
2593 The i960 uses this for more detailed fault information.
2595 * remote.c (remote_open): If arg is null, print help rather than
2598 * sparc-xdep.c (register_valid): Avoid declaring size, since
2599 various modules will think of various sizes depending on the
2600 architecture of their tm-file. FIXME, we need protection against
2601 actually entering one of those modules, which would clobber
2602 storage if not for the target architecture compiled into gdb.
2604 * stack.c (up_command, down_command): Always print the frame
2606 (up_silently_command, down_silently_command): New commands
2609 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2611 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2612 more parameters than it used to.
2614 * findvar.c (registers): Increase slop to 256 bytes, which should
2615 protect us against even most RISC machines with large register
2617 (locate_var_value): Move declaration inside related ifdef.
2619 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2620 throughout, to avoid throwing away buffered input from the board.
2621 (nindy_wait): Supply_register takes addr_of_value, not value.
2622 (i960_print_fault): Renamed from i80960_fault.
2623 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2624 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2626 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2627 we can set the PC in the call to proceed(). Unpush nindy_ops
2628 before pushing it on top, to avoid message to user. Eliminate
2629 commentary from Unix machines that just misleads here.
2630 (reset_command): Fix error message to suggest target command.
2632 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2634 Release 3.92.5 as frozen.
2636 Stabilize the merged release...with help from lint, Saber C,
2639 Everywhere: Add include files needed to declare return types
2640 of functions called.
2642 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2644 * breakpoint.h: Add undeclared breakpoint functions, and some
2645 functions for display handling since I couldn't think of a better
2648 * breakpoint.c (insert_breakpoints): Make code for disabling
2649 shared library bkpts more likely to work. It's used when we
2650 rerun a program and stop before the shared library has been
2652 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2653 cast from pointer, so it squeezes through catch_errors.
2654 (bpstat_stop_status): Fix logic broken some time ago. We now
2655 always create a bpstat if the stop address matches a breakpoint,
2656 even if we don't stop there -- just like the old code used to do
2657 before I got my fingers into it (sigh).
2658 (breakpoint_1): Print "ignore count" after "stop only if"
2659 condition, since that's how it actually works.
2660 (mention): Handle watchpoints as well as breakpoints.
2661 (watch_command): use set_raw_breakpoint and mention to do most
2662 of the work (and initialize all the fields!). Only pass one
2663 arg to parse_c_expression, since that's all it takes.
2665 * command.c (not_just_help_class_command): Rename arg to args
2666 since we ignore "unused argument" warnings on vars named "args".
2667 inflow.c (child_terminal_info): ditto.
2668 infptrace.c (kill_inferior): ditto
2669 main.c (catch_errors, version_info, quit_command, pwd_command,
2670 source_command, dump_me_command, editing_info,
2671 set_history_size_command, set_history, show_history,
2673 stack.c (locals_info): ditto
2674 target.c (target_files_info): ditto
2675 valprint.c (set_input_radix, set_output_radix): ditto
2677 * core.c: Remove old variables for handling core and exec file
2678 sections (data_start, data_end, stack_start, stack_end,
2679 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2680 text_end, exec_data_start, exec_data_end, text_offset,
2681 exec_data_offset, data_offset, stack_offset). They're
2682 superseded the more general build_section_table and
2684 (get_exec_file): Mention the `file' command.
2685 (read_memory_check): Rename to memory_error, and only call it
2686 in the case of an actual error.
2687 (read_memory, write_memory): call memory_error.
2688 (core_fetch_registers): Register section name is ".reg".
2690 coredep.c: Remove a bunch of crud now that all this file does
2691 is pull the registers out of a core file.
2692 (fetch_core_registers): Rewrite to actually work, I hope.
2694 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2695 Replace index() with strchr(). Remove all the pre-BFD macro
2696 definitions for accessing the symbol file.
2697 (struct dbx_symfile_info): Encapsulate the information that
2698 dbx_symfile_init needs to pass to dbx_symfile_read in this
2701 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2702 dbx_symfile_discard): Rearrange symbol file reading to divide
2703 the format-specific part from the format-independent part,
2704 leaving the format-independent part such as file name expansion
2705 and opening in symtab.c. This replaces
2706 partial_symbol_file_open and partial_symbol_file_read.
2707 Symbol_file_read, add_file, add_file_target_command,
2708 add_file_addr_command move to symtab.c. Pass an explicit
2709 "mainline" flag for when reading the main symbol table, rather
2710 than relying on the offset address to be zero or nonzero.
2712 (dbx_symfile_read): Don't allow void *'s to be printed as
2714 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2715 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2716 macro" debug version really work.
2717 (read_dbx_symtab): Remove unref'd parameter inclink.
2718 Avoid swapping N_SLINE symbols, for speed.
2719 Merge N_TEXT!N_EXT case with the other external symbol
2720 definitions' case. Add comments.
2721 (start_psymtab): Allocate the symfile name in the psymtab on
2722 the psymbol_obstack, rather than using the caller's storage.
2723 (end_psymtab): Only allocate a dependencies list if there are
2725 (psymtab_to_symtab_2): Use BFD when reopening file to read
2726 its symbols for real.
2727 (read_struct_type): Add FIXME comments where it needs work
2729 (read_huge_number): Add FIXME about overflows.
2730 (read_range_type): Add FIXME about comparing a long to 1<<32.
2732 * coffread.c: Minor changes to move things closer to the new
2733 regime with symtab.c and dbxread.c Major work is still needed
2736 * exec.c (exec_file_command): Remove old variables (see core.c
2738 (xfer_memory): If memory transfer is right at the end of a
2739 section, don't lose.
2741 * findvar.c (get_saved_register): If value is in a real
2742 register, LVAL is lval_register, not lval_memory.
2744 frame.h: Declare print_sel_frame and record_selected_frame.
2746 gdb-int.texinfo: New file, for GDB internals documentation.
2747 Very simple, unformatted doc of cleanups is there for now.
2749 gdbcore.h: Remove obsolete variables that described a.out
2750 section addresses and offsets. (See core.c above.)
2751 Declare fetch_core_registers and registers_fetched.
2753 getopt.c: Declare char *alloca(); even on SPARC.
2755 infcmd.c (run_command): Call target_kill rather than
2757 (step_command, next_command, stepi_command, nexti_command):
2758 Declare from_tty parameter even though we don't use it.
2759 (run_stack_dummy): argument BUFFER is a char array, not
2760 a pointer to REGISTER_TYPE.
2761 (finish_command): using_struct_return needed a value *,
2762 not a struct symbol *.
2764 * infptrace.c (child_xfer_memory): To avoid dependency on
2765 where sections are in memory, try PT_WRITE_D and if that fails,
2766 try PT_WRITE_I. Most Unixes don't care which you use.
2768 * infrun.c (step_resume_break_shadow): Change to array to
2769 match other breakpoint shadow storage.
2770 (clear_proceed_status): Pass address of bpstat to
2771 bpstat_clear, not the bpstat itself.
2772 (child_create_inferior): FIXME comment about if the child
2774 (start_inferior): Remove old function.
2775 (child_open): Use target_kill rather than kill_inferior.
2776 (wait_for_inferior): Ditto.
2777 (insert_step_breakpoint, remote_step_breakpoint): Use
2778 new step_resume_break_shadow.
2780 * inftarg.c (child_wait): If all child processes die,
2781 pretend that the one being waited for exited with signal 42.
2783 * main.c (command_line_input): When scanning for comments,
2784 don't coredump on unclosed quotes.
2785 (quit_command): Use target_kill rther than kill_inferior.
2786 (_initialize_main): Rename class_user from "user" to
2789 * printcmd.c (print_command_1): Initialize "fmt" if no format
2790 is specified by the user.
2791 (print_frame_args): Only add to args_printed if we are
2792 actually fetching args from the stack (avoiding undefined
2794 (_initialize_printcmd): Remove bogus \{ from string.
2796 * remote-eb.c (eb_open): Avoid coredump on no argument.
2798 * remote-nindy.c: Bring out of Intel environment into new
2799 target environment. Remove all conditional compilation on
2800 I80960. Massive hacking throughout.
2801 (nindy_xfer_inferior_memory): New routine stolen from
2803 (nindy_create_inferior): New routine pieced together, probably
2804 not quite working yet.
2805 (nindy_ops): New target_ops struct for nindy.
2807 * remote-vx.c: Use write_memory rather than target_write_memory
2808 to get error checking.
2809 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2811 (vx_create_inferior): Use target_terminal_ours...
2813 * signame.c (_initialize_signame): Always initialize, since
2814 we need the table for things other than psignal.
2816 * solib.c (solib_add): Use symbol_file_add, not add_file.
2817 (solib_address): Return boolean result rather than struct
2818 pointer which nobody else knows the type of.
2820 * sparc-tdep.c, valops.c: Use write_memory rather than
2821 target_write_memory, to get error checking.
2823 * stack.c (locals_info, catch_info, args_info,
2824 get_selected_block, frame_command, up_command): Use
2825 target_has_stack, rather than have_inferior_p or
2828 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2830 * symfile.h: New file, defining the interface between the
2831 generic and object-file-specific symbol reading code.
2833 * symtab.c: Move generic symbol-reading interface to symtab.c,
2834 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2835 table to map BFD targets to symbol-reading modules in GDB.
2836 Change index to strchr.
2837 (lookup_struct_elt_type): Use error() rather than hand-made
2838 simulations thereof.
2839 (lookup_partial_symbol): Speedup slightly when length == 0.
2840 (symbol_file_add): New function.
2841 (symbol_file_command): Call it.
2842 (symfile_open, symfile_init): New function.
2843 (add_file_target_command, add_file_addr_command): moved from
2846 * target.c (target_command): use target_kill.
2848 * target.h (target_files_info): Don't declare, never called
2851 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2852 files to determine stack end address.
2854 * valarith.c (value_x_binop, value_x_unop): Change error message
2855 to be more useful. Pass proper argument to value_struct_elt.
2857 * valops.c (value_assign): FIXME comment that long long
2858 bitfields will break here.
2860 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2861 Update `make saber_gdb' to work better.
2863 * TODO: A woman's work is never done.
2865 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2866 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2867 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2868 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2869 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2870 valops.c, valprint.c, exec.c: Lint.
2873 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2875 Continuing Intel 960 port merge of GDB.
2877 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2878 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2879 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2880 Wack over "make depend" so it handles files in subdirectories
2881 vx-share, nindy-share, bfd, and in the current directory.
2883 * blockframe.c (get_prev_frame_info): Remove fatal error
2884 if stack not defined.
2886 * core.c (core_open, core_detach): New functions that handle
2887 the old "core-file" command as "target core" and "detach" instead.
2888 (core_file_command): Call them.
2889 (core_xfer_memory): Use common routine xfer_memory.
2891 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2892 dbxread now uses bfd for everything but symbol reading itself.
2893 BFD internals are used to drag out the relevant file offsets.
2894 (partial_symbol_file_open): Change args all around for BFD.
2896 * symtab.c: Rename "value" to "val" everywhere, so we can
2898 (symbol_file_command): New command, moved from dbxread.c
2899 and coffread.c. It uses BFD to read the file, then vectors
2900 based on its type, to dbx or coff symbol readers.
2901 * symtab.h: Extern a few vars for symbol_file_command.
2903 * target.h: Breakpoint takes a char * save area, not a char **.
2905 * valprint.c (val_print): When unpacking bitfields, offset
2906 the address in gdb of the value, if it is declared with a shorter
2907 type. Remove the last "runtime kludge test" of host byte order.
2909 * utils.c: Remove old my_bfd_read routine.
2911 * stack.c (frame_info): Use target_has_stack. Print program counter
2912 register's actual name rather than "pc", since it's called the
2913 "ip" (instruction pointer) on the i960 (sigh).
2915 * target.c (target_command): Add command for selecting a target
2916 type and calling its open routine. This is used for initiating
2917 communication with a particular target, in a generic way.
2919 * tm-i960.h: Update for modern gdb. Remove semicolons from
2920 various macros. Handle reading struct return convention, and
2921 error-out attempts to return structs with the "return" command.
2922 Be sure gdb doesn't think we know how to call functions in the
2925 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2926 to i960_xxx in lower case.
2927 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2928 not being defined yet.
2930 * remote.c (remote_open): Call start_remote to initialize
2931 wait_for_inferior during open.

2941 (wait_for_inferior): Clear saved register values before target_wait,
2942 so target_wait can set some of them if convenient.
2944 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2945 Return success indicator, not void.
2946 (child_xfer_memory): Avoid fetching initial word if we'll
2947 overwrite it anyway.

3006 Thu Apr 19 09:54:28 PDT 1990
3007 Add 'reset' command.
3009 Wed Apr 18 09:48:07 PDT 1990
3010 After opening remote tty, wait for 1 second to go by without input
3011 from it before trying to talk to NINDY (fixes problems with the
3012 Heurikon HK80/V960E).
3014 Mon Apr 4 16:33:05 PDT 1990
3015 Some output was not being suppressed in 'batch' mode.
3017 Thu Mar 22 15:31:11 PST 1990
3018 Ask user if old symbol table should be deleted when new file is
3021 Allow user to run a program downloaded before gdb960 was brought up.
3023 Correct "exec-file" help message for i80960 context.

3056 - moved 960-specific routines from i960-pinsn.c to i960-md.c
3057 - made disassembly interface identical to that in gdmp960.
3061 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
3063 * target.h: Allow targets to stack. Add target_has_memory,
3064 _registers, etc. Restructure memory access and "info files"
3065 to walk the target stack.
3066 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
3067 target.c: Change tables to match target.h.
3068 * inflow.c (child_mourn_inferior): pop child_ops.
3069 (generic_mourn_inferior): Use new has_stack flag.

3072 * remote-eb.c: New memory regime, new info files.
3073 * remote-vx.c: New memory regime, new info files. Now use
3074 separate targets for VxWorks attachment to machine, and
3075 actually running a process under VxWorks, since one has
3076 stack & execution & regs and the other doesn't.
3077 * remote.c: New memory regime, new info files.
3078 * sparc-xdep.c (fetch_core-registers): New memory regime.
3079 * target.c: New routines and support for stacked targets,
3080 new memory regime, new info files regime.
3083 Generalize section handling for an arbitrary number of sections,
3084 including use of the new BFD (binary file) library.
3085 * gdbcore.h: Add struct section_table.
3086 * exec.c (build_section_table): Iterate all sections and
3087 record what gdb needs to know about them.
3088 (exec_command): Use it.
3089 (exec_xfer_memory): Use the table.
3090 (exec_files_info): Print the table.
3091 * core.c (core_file_command, core_xfer_memory, core_files_info):
3093 * source.c (find_source_lines): Use bfd_get_mtime.
3094 * dbxread.c: Quick changes to make it compile with new BFD.
3095 * utils.c (error): Avoid using bfd_error in generic routines.

3099 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
3101 * inferior.h (attach_flag): Export.
3102 * infcmd.c (run_command): use new target_create_inferior.
3103 * infrun.c (child_create_inferior): Don't return result.
3104 * Makefile.dist (VERSION): 3.91.4.

3112 * core.c (core_file_command): Display the frame where the core
3117 * remote-vx.c (target_command): Merge in target command from
3118 targ-vx.c. A few other cleanups.
3120 * TODO, Projects: Lots more stuff to do...
3122 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
3124 Massive changes to wall off the remote-debugging interface
3125 behind a function vector. The port to handle VxWorks targets
3126 is also part of this.
3128 All files: Replace references to renamed functions,
3129 remove references to remote_debugging, remove references to
3130 have_include_file, have_core_file in favor of target_has_stack,
3131 target_has_memory, etc.
3133 * Modularize the breakpoint interface.
3134 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
3135 a breakpoint instruction.
3136 breakpoint.c: struct breakpoint's shadow_contents now sized as
3138 (insert_breakpoints): Vector to target to install breakpoints.
3139 (remove_breakpoints): Vector to target here too.
3140 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
3141 sparc-tdep.c (single_step): Use new breakpoint interface for
3142 the single-step breakpoints.
3143 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
3144 New file, contains routines to insert and remove breakpoints by
3145 reading out the old contents and later replacing them. This is
3146 how ptrace breakpoints work, and many remote systems as well.
3148 * tm-vxworks68.h: New config file, overrides a few things for
3149 Wind River's preferences.
3151 * target.h: New file, for transfer vector used to talk to the
3152 inferior (child, attached, core, exec, remote, etc). All accesses
3153 to the thing being debugged should come through these vectors.
3154 target.c: New file, routines to handle transfer vector.
3155 (various files): Add transfer vectors XXX_ops for the various
3156 targets and pseudo-targets (core files, etc) we support.
3158 * breakpoint.c (bpstat_stop_status): Further explorations of
3159 watchpoints and why things don't work all the time.
3160 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3162 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3163 the local gdbinit if it doesn't already have it.
3165 * core.c (core_ops): add and install.
3166 Allow core debugging without exec file.
3168 * dbxread.c (free_and_init_header_files): Merge two fns.
3169 (end_symtab): Free named symbol table when a new version comes in.
3170 (read_dbx_symtab): Relocate all kinds of symbols with base
3171 address. First step toward handling different text, data, bss
3173 (add_file_addr_command): Renamed add_file_command.
3174 (add_file_command): Vector to remote handler.
3175 Add "load" as an alias for "add-file" command.
3177 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3178 non-returning functions.
3180 * exec.c: Add exec_ops, and push it as a target when an exec
3183 * infcmd.c (run_command): Pass executable file name and arg list
3184 separately when starting an inferior. Permit "run" when no exec
3185 file is specified, for VxWorks.
3186 (detach_command): Move to child_detach in inftarg.c.
3188 * inftarg.c: New file. Unix-child-specific routines, and the
3189 child_ops structure.
3191 * inferior.h (registers): Export "registers" as the way for
3192 target dependent register handlers to find gdb's local copy of
3193 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3194 since it is now used by places that want wait_for_inferior to
3195 handle the grunge but want to see every trap from the inferior.
3197 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3198 Eliminate remote_debugging hooks in terminal handling.
3200 * infrun.c: Replace start_inferior with child_create_inferior.
3201 Move all the hair of Unix shells and ptrace idiosyncracies into
3202 child_create_inferior, so remote handlers don't have to deal.
3203 Remove running_in_shell. Rename stop_after_attach to
3204 stop_soon_quietly, and use it in a few other places where we want
3205 to just call wait_for_inferior and get control back on the first
3206 trap. trap_expected now never takes a value > 1.
3207 (init_wait_for_inferior): Initialize static vars when a new
3210 main.c (gdbinit): Add new hook for .gdbinit file name, let
3211 it be overridden by config files as GDBINIT_FILENAME.
3212 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3213 Both of these are used for VxWorks gdb.
3215 mcheck.c: rename include file "gmalloc.c" to avoid problems
3216 with system include file "malloc.c".
3218 param-no-tm.h: New include file, same as param.h but does not
3219 include the default "tm.h" file. This is used in files where
3220 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3222 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3224 remote-vx.c: New file, VxWorks remote debugging support. Uses
3225 RPC routines that are shared with the target system, in directory
3228 remote.c: Vectorize remote interface.
3230 source.c: Globalize source_path, and make an alias "l" for "list"
3231 since we now have the "load" command.
3233 sparc-xdep.c: Use new param-no-tm.h.
3235 symmisc.c (free_named_symtab): Add new function from Wind River.
3236 However, ifdef it out for now while we think about what it should
3239 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3241 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3242 non-Unix-children handle this with their own code in the target
3245 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3246 source and target lists. Add vx-share to default list of include
3247 directories. Add new files to src and target lists: mem-break,
3248 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3249 ${srcdir} versions of munch and createtags are used.
3251 * valops.c (find_function_addr): Split out of call_function.
3252 (call_function_by_hand): Rename call_function; this function
3253 calls functions in the target by laboriously patching the target
3254 word-by-word with the right stack, args, regs, etc.
3257 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3259 Handle AMD 29000 a bit better.
3261 * remote-eb.c (readchar): Mask received char log to make it readable.
3262 (remote_start): Pass arguments down to executing program.
3263 Make startaddr unsigned.
3264 infrun.c (start_inferior): Accept args, pass them to
3266 infcmd.c (run_command): Pass args down to start_inferior.
3268 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3269 the target object file format.
3270 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3272 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3273 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3275 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3277 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3278 * TODO: We did a few things, we have more to do though.

3286 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3287 (sparc_push_dummy_frame): Simplify and fix what we push.
3288 (sparc_pop_frame): Slightly more hair here, deciding whether
3289 we are restoring a saved PC or returning to a return address in %i7.
3290 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3292 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3293 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3294 * obstack.h (chunkfun): ditto.
3295 * defs.h (xmalloc, xrealloc): ditto
3297 * utils.c (quit): Grab the terminal from the child if necessary.
3299 * inflow.c (term_status_command): Rename to term_info, change
3302 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3303 (is_delayed_branch): Speed up.
3304 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3305 Still missing some float ops, and needs testing.
3307 * Support for input and output radixes other than base 10
3308 * defs.h (input_radix, output_radix): Declare.
3309 * expread.y (yyparse, parse_number): Handle changes of input
3310 radix, and ambiguous names-or-numbers in radixes >10.
3311 * printcmd.c (print_scalar_formatted): Print formatted hex
3312 numbers in varying column widths.
3313 * valprint.c (val_print): Use output_format to print scalar ints.
3314 (set_input_radix, set_output_radix, set_radix): Create.
3315 (set_output_radix): Set output_format from output_radix.
3316 (_initialize_valprint): add `set radix' but leave the others off.
3318 * main.c (execute_command): Let stupid questions be turned off.
3319 (_initialize_main): Handle "set stupidity", etc.
3321 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3322 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3324 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3326 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3327 bfd stuff is still screwed up, but with some manual work, it
3330 * breakpoint.c (bpstat_do_actions): Start over if a command
3331 proceeds the inferior, since the inferior will have stopped and
3332 will need to have its new stop-actions taken care of.
3334 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3335 compiler fits, simplify it.
3337 * gdb.texinfo (directory command): Doc new dir command.
3338 source.c (directory_command): "dir" now puts things on the front
3339 of the path, moves dups up front, and handles multiple names
3340 on the command line, inserting each one in order. It also
3341 blows away cached line and full_filename info.
3343 * stack.c (backtrace_command): Skip "more stack frames follow"
3346 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3347 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3348 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3349 The only odd one was Gould NP1, which had defined vprintf to
3352 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3353 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3354 variable, inspect_it.
3355 valprint.c (print_string, val_print): Use the global inspect_it
3356 to indicate whether to print in Epoch style or normal style.
3358 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3360 * printcmd.c (call_command): add an alias for the "print" command
3361 which runs expressions and doesn't print the result if void.
3362 (print_command_1): implement it.
3364 * command.c: Remove #if 0'd code. Initialize all the fields
3365 in add_cmd (). Rename do_nothing_command to
3366 not_just_help_class_command, and make it externally visible.
3367 command.h: add user_commands to struct.
3368 * main.c (define_command): Don't overload c->function with a char
3369 string as well as a function pointer.
3371 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3372 calling convention of value_struct_elt () that got dropped in
3375 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3376 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3378 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3380 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3381 until a good time (e.g. when we are about to run the child),
3382 saving ptrace calls.
3383 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3384 * tm-sparc.h: define DO_DEFERRED_STORES.
3386 * sparc-xdep.c (store_inferior_registers): when storing float
3387 registers, don't store stack regs too. When storing the SP,
3388 however, DO store the stack regs too. This fixes a bug in which
3389 the dummy frame is not recognized when a call_function finishes,
3390 because its frame pointer (in the stack regs) was never
3392 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3393 even though we don't know how to read them from an inferior.
3394 valops.c (call_function): Comment about storing SP.
3396 * infrun.c (save_inferior_status): Save away the original bpstat
3397 chain so it can be restored later. Install the copied version for
3398 use by whoever saved the status. It will be blow away by
3399 restore_inferior_status, and the original chain restored. This is
3400 important for people who have pointers into the original.
3402 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3403 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3404 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3407 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3409 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3410 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3411 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3413 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3415 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3416 Store the baseclasses in a type struct starting from array element
3417 0 rather than from the unusual array element 1.
3419 dbxread.c: the above.
3420 (virtual_context): Add
3421 Read new debug information about which virtual function table
3422 a virtual function is from, and store it in fn_field.fcontext.
3424 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3425 TYPE_FN_FIELD_STATIC_P.
3427 symtab.c: the above.
3428 valops.c: the above. Handle pointer casts of object *'s.
3429 (search_struct_method): Add.
3430 (value_struct_elt): First arg is now a pointer to a value, and is
3433 valprint.c: the above.
3434 values.c (value_virtual_fn_field): Add type arg. Handle
3435 offsetting to the proper object when calling virtual fns.
3437 (baseclass_addr): Add valuep arg.
3439 * README: Document the current state of BFD config (missing).
3440 * TODO, ChangeLog, Makefile.dist: Roll version.
3441 * WHATS.NEW: Add summary of changes since 3.5.
3443 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3445 * dbxread.c (read_struct_type): Clear bit vectors whenever
3447 symtab.c (B_CLRALL): define.
3449 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3450 using == rather than =. Huh... This fixes the dreaded problem
3451 wherein builtin_type_int becomes TYPE_CODE_FLT.
3453 * core.c (info_files): Show the inferior pid.
3455 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3456 already knows how to look in the source directory.
3458 * Remove psymtab hair from many places. Remove duplicated code
3459 for searching symbol tables. Hide psymtabs from most places.
3460 Make it fast to get from a psymtab to its symtab.
3462 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3463 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3464 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3465 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3466 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3467 new symtab completely. New psymtabs get symtab pointer
3468 initialized to zero. Remove MI warning printf.
3469 symtab.h: Comments. Add psymtab to symtab pointer.
3470 (PSYMTAB_TO_SYMTAB): New macro.
3471 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3472 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3474 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3476 (print_frame_info): Avoid special-casing symbols that have not yet
3479 * source.c (open_source_file): Quick path if we have already
3480 located the source file by its full name.
3482 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3483 find_pc_psymtab. When a name is found in the misc function
3484 vector, search the symbol table for its mangled name, not the
3485 name that the user typed.
3487 * bfd.h: Fix missing comment terminators, make #endifs match.
3489 * valarith.c (value_less): Handle unsigned int comparisons.
3490 Add FIXME about pointer compares, which assume host and target
3491 pointers are the same.
3493 * command.c (do_nothing_command): lint
3494 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3495 fix comments on debug symbol format for visibility. Actually set
3496 visibility of symbols.
3497 main.c (echo_command): lint; use <readline/history.h>.
3498 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3499 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3500 pointing past end of allocated memory; saber complains.
3501 obstack.h: Declare the external functions that we use.
3502 valarith.h: use <string.h>
3503 solib.c (solib_add): lint.
3505 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3507 * main.c (initialize_main): Default info_verbose to off, now that
3508 symbol reading is fast.
3509 (quit_command): Avoid clobbering exec_bfd while quitting.
3511 * Initial BFD (binary file diddling library) merger:
3512 coffread.c: Change AOUTHDR to struct exe_hdr.
3514 core.c: initialize initialized data at compile time.
3515 (core_file_command): Move from coredep.c, convert to bfd.
3516 (xfer_core_file): Convert to bfd.
3517 exec.c (exec_file_command): use bfd routines.
3519 mips-tdep.c: Remove exec_file_command and friends.
3522 * coredep.c: (fetch_core_registers) Convert core_file_command to
3523 fetch_core_registers.
3524 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3526 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3527 (my_bfd_read): More bogosity, which I don't think we call.
3528 (program_name): Remove this atrocity asap!
3530 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3533 values.c: allocate_repeat_value was not clearing the
3534 optimized_out field.
3535 (value_static_field): minor stylistic fix (wrong macro was used).
3536 valops.c (value_struct_elt_for_address): didn't work for C++
3539 * signame.c (_initialize_signame): Initialize signal names once.
3541 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3542 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3543 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3545 * remote-eb.c: Support user-settable baud rates on the serial port.
3547 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3549 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3551 * tconfig/sun3os4: Remove warning about native assembler,
3552 since it also occurs in the xconfig file.
3554 * findvar.c (registers): Allocate some slop after `registers'
3555 to prevent stray accesses from trashing the next variable.
3557 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3558 on the sun-3, by changing the #ifdef from `sun3' (which is not
3559 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3560 vars, which happened to follow `registers' in the executable.
3562 * readline/history.c (history_search): Heed gcc-2's advice
3563 and parenthesize && inside ||).
3565 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3566 tm-29k.c: Insert FSF copyright headers.
3568 * remote-eb.c: Better comments.
3570 * Makefile.dist: Update to 3.91.6.
3571 * TODO: note PREPARE_TO_STORE problem.
3573 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3575 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3577 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3579 * infrun.c (wait_for_inferior, at end): Don't set up
3580 prev_* if the inferior no longer exists.
3582 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3583 CANNOT_EXECUTE_STACK.
3584 valops.c (call_function): Use it.
3586 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3588 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3589 infrun.c (wait_for_inferior, 2 places): Use it.
3591 * values.c (value_being_returned): Only use
3592 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3594 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3595 right thing for remote-eb.c.
3597 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3598 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3600 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3601 (FRAME_FIND_SAVED_REGS).
3603 * findvar.c ({fetch,store}_registers): Check for
3604 REMOTE_{FETCH_STORE}_REGISTER macro.
3606 * findvar.c (get_saved_register): Add argument lval and
3607 change meaning of argument addr.
3608 findvar.c: Change calls to get_saved_register to reflect
3609 new calling convention.
3610 valops.c (value_assign): Use get_saved_register instead of
3611 find_saved_register.
3613 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3615 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3616 an (uninitialized) pointer to one. Use "&" when passing it
3619 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3621 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3624 * coffread.c (symbol_file_command): Put semicolon after
3626 Put safe_to_init_tdesc_context in #if defined (TDESC).
3627 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3628 coffread.c: #include <sys/stat.h>.
3629 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3630 Add missing ')' in check for "lc%" and friends. Remove
3632 Declare read_one_sym() at top of file.
3633 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3634 MC68WRMAGIC can have the same value without causing a duplicate
3637 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3639 * Allow a Makefile to be built without building the
3640 tm and xm file links that screw up builds in subdirectories.
3641 This is done with `config.gdb none', then you can do things
3642 like `make gdb.tar.Z'.
3643 * tconfig/none: Config file for no target system
3644 * xconfig/none: Config file for no host system
3645 * config.gdb: If no TM or XM files are called out by the
3646 host or target file, don't make links for them.
3648 * cplus-dem.c: Add documentation.
3650 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3651 simple error, so the user's gdb doesn't crash due to some object
3652 file problem (e.g. somebody is rebuilding the file out from under
3655 * printcmd.c (print_address_symbolic): demangle the symbol.
3657 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3658 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3659 (alldeps.mak): sort and uniq all results from this; duplicates
3660 hose gdb.tar.Z link building. Remove RCS files from
3661 tconfig and xconfig. Add config files for sun386. Add
3662 a few odd files to OTHERS and HFILES.
3664 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3666 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3667 Roll version number to 3.91.5. Make lint work in bindir.
3669 * README: Document cross-debugging and new file structure.
3671 * blockframe.c: Lint. Include "value.h" to declare read_register.
3672 (find_pc_partial_function): remove duplicate line.
3674 * command.h: Lint. Declare error_no_arg and dont_repeat.
3676 * tm-news.h: Remove inadvertently duplicated stuff.
3678 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3679 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3681 * config.gdb: Allow `config.gdb host target' form. Clean
3682 up previous change that printed bogus messages when you just said
3685 * core.c: #include "command.h" for lint.
3688 * main.c: Remove some casts of enums. Lint.
3695 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3697 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3698 read it from memory. This will allow us to save ptrace calls
3699 eventually. Changed caller single_step too.
3701 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3702 that we aren't going to use, saving many ptrace calls, especially
3703 when watchpointing or single stepping. Use some #define's for
3705 (store_inferior_registers): Ditto.
3706 (core_file_command): Use some #define's for constants.
3708 * tm-sparc.h: Add #define's for some register numbers, so we
3709 can eliminate the use of random constants in sparc-xdep.c.
3711 * stack.c (frame_command, print_frame_info, up_command,
3712 down_command) Remove frame_changed, since it
3713 causes a bug and doesn't seem to do anything useful. In some
3714 places it was used as a flag, in others as a stack level (?).
3716 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3717 default is to use the portable (vprintf) version rather than the
3719 * xm-news.h (MISSING_VPRINTF): Add.
3721 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3723 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3725 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3726 about linking debugged programs -Bstatic in the sun?os4 config
3727 files in tconfig and xconfig subdirectories.
3729 * main.c (main): Remove unreached exit(0) now that we exit
3732 * Create TODO file for online bug list. There are too many
3733 "little" bugs to keep track of on paper.
3735 * Change Projects file to refer to bug-gdb@cygnus.com
3736 rather than kingdon@ai.
3738 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3740 * Makefile.dist (VERSION): 3.91.4 now.
3742 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3743 (condense_misc_bunches): Add sanity check that misc_count is
3744 the same as the number of symbols in the bunch.
3746 * coffread.c: rename init_misc_bunches. Pass an argument
3747 to condense_misc_bunches (a zero).
3749 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3750 every time we are called; don't rely on our caller to do it.
3751 (add_file): Remove call to init_misc_bunches.
3753 * mipsread.c: Only warn, don't error, if unknown symbol types.
3754 This keeps an old gdb from falling on its face if it sees newly
3755 extended symbol info. Rename init_misc_bunches.
3757 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3759 * Merge in changes from Per Bothner for DECstations and other
3760 MIPS stuff. The rest is Bothner speaking:
3762 The next message is a merger of Alessando Forin's mips port with
3763 mine. I've tried to use my good if biased judgment to get
3764 the best of both. It *does* need testing.
3766 Some of the changes are general, *not* mips-specific.
3769 Didn't believe in little-endian bit order.
3770 There are still inconsistencies about whether flags
3771 like BITS_BIG_ENDIAN are integer (#if ...) or
3772 boolean (#ifdef ...). I tried to paper over them.
3774 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3775 Moved some misc_function code that was common to
3776 {dbx,coff,mips}read.c to symtab.c.
3777 In the process, I think I cleaned things up a bit.
3778 At the same time, moved obsavestring and obconcat to symtab.c.
3781 Removed obsolete condense_addl_misc_bunches (use
3782 condense_misc_bunches(1) instead).
3785 Needed to include <sys/dir>, at least on DECstations.
3787 valops.c, mips-tdep.c, tm-mips.h:
3788 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3789 conventions (when STACK_ALIGN is insufficient).
3790 Needed on mips, where doubles need 8-byte alignment,
3791 but ints only need 4.
3794 Removed cruft that was not being used.
3795 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3798 Print $ before register-names (I think that makes things a little
3800 Never print two instructions, even if one delays.
3801 Removed hex-disassemble set_cmd. (This is not mips-specific,
3802 so I think the argument is whether it is generally worthwhile or not.
3803 I'm inclined to think not, given how easy it is to
3804 convert between radixes in gdb.)
3807 This is basically Alessando's code.
3808 It doesn't use obstacks; I changed it to use obstacks
3809 in a few minor places where using malloc causes a
3810 memory leak. (Probably, more places could/should be changed.)
3811 I added record_misc_function where it was missing.
3812 In symbol_file_command and add_file_command, I tried
3813 to make the code consistent with more recent versions.
3814 Minor sylistic changes in parse_procedure.
3815 Make a .gdbinfo. psuedo-symbol point back to the real
3816 procedure symbol (using the isym field).
3819 This is basically from my port, but with a lot of details
3820 and a number of routines merged in from Alessando's version.
3821 I basically used my code "raw" backtrace (use heuristics
3822 from the actual code, rather than symbol table info) - though
3823 the idea is Alessandro's. I feel my code is a little cleaner
3824 here, particularly in being a little more flexible, such as being
3825 able to handle gcc-produced code (which it now can).
3826 It also doesn't do frame caching (which is not useful
3827 more recent gdb versions).
3828 I also used my code for push_/pop_dummy, more or less.
3829 I tried to incorporate AF's code for testing sigtramp
3830 while backtracing; I probably got it wrong.
3831 Added mips_print_register, which tries to scrunch as much
3832 information as possible on a screen...
3833 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3834 under mips-pinsn.c), I don't see anything mips-specific here,
3835 and I don't see it being all that useful anyway.
3838 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3839 Use more register names (rather than hard-cases numbers).
3841 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3843 * Hack up 3.90.11 changes:
3845 * Makefile.dist (depend): parameterize $(GCC).
3846 Add solib.c and solib.o.
3847 (readline): Fix vpath for both absolute or relative SRCDIR.
3849 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3850 Also, let the part I didn't understand at least compile so
3851 I can test the rest. FIXME.
3853 * dbxread.c: Fix thinko using strcmp.
3854 (init_psymbol_list): declare static.
3855 (partial_symbol_file_open): Comment cleanups better, avoid
3856 cleaning up the string table since the caller will do that.
3857 Move the stat for mod time into symbol_file_command, temporarily.
3858 (There should be a mod time for each symbol file, eventually,
3859 to control its rereading. FIXME.)
3861 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3862 SunOS, which gives error for shared libs otherwise. (From
3863 Schaefer, probably FIXME needs work for portability.)
3865 * solib.c: Move #include "param.h" to work.
3866 Lowercase all the Uppercase Letters In the Messages.
3867 (find_solib): Clean up inferior_so_name for debug printouts.
3868 Allow no argument, to mean all shared libraries.
3870 * symmisc.c: include param.h to get CLEAR_SOLIB.
3872 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)

3918 Take code which is shared between symbol_file_command and
3919 add_file_command and put it into partial_symbol_file_{open,read}.
3920 Split add_file_command into add_file_command and add_file.
3921 Make psymtab_to_symtab read in the string table if the file
3923 Two new parameters to read_dbx_symtab and start_psymtab.

3943 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3945 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3947 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386

3970 consistency with POSIX.
3972 * breakpoint.c (bpstat_stop_status): Disable watchpoint

3977 * Makefile.dist: Bump version to 3.91.3.
3979 * Clean up handling of breakpoint commands (somewhat).
3980 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3982 inferior.h: Add breakpoint_proceeded to inferior status struct
3983 and globals; save it and restore it.
3984 (clear_breakpoint_commands): Cleanup, remove old #define.
3986 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3987 (save_inferior_status, restore_inferior_status): handle it also.
3988 (proceed): Remove earlier code that set breakpoint_proceeded.
3989 It is now set only in clear_proceed_status.
3990 (clear_proceed_status): Cleanup, use bpstat_clear rather
3991 than clear_breakpoint_commands. No callers need the stop_bpstat
3992 between clear_proceed_status and proceed.
3994 infcmd.c: Add breakpoint_proceeded definition and comment.
3995 (cont_command, jump_command, signal_command): Move call to
3996 clear_proceed_status right next to call to proceed.
3998 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3999 caller's argument while running down the chain of breakpoints.
4000 Use new variable "breakpoint_proceeded" to determine when
4001 a command that it executes moves the inferior past the
4003 (bpstat_clear): Handle NULL argument.
4004 (bpstat_clear_actions): Avoid useless call to
4005 breakpoint_auto_delete.
4006 (delete_breakpoint): Clean up bpstat's that are pointing to
4007 the deleted breakpoint from the stop_bpstat chain.
4008 (breakpoint_auto_delete): Simplify.
4010 * Clean up handling of EOF, error on stdin, etc. This was
4011 prompted by a network problem that caused gdb to go into an
4012 infinite loop filling up its malloc'd memory.
4014 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
4015 not clear_breakpoints_commands, which is now gone.
4016 (main): If command_loop returns (e.g. from EOF on stdin), do
4017 a quit_command (looping back to command_loop if quit_command
4018 doesn't really quit).
4019 (command_loop): check result from command_line_input and
4020 exit if it returns NULL, rather than passing the NULL to
4022 (gdb_readline): Free malloc'd result space before returning
4025 * utils.c (query): Handle C-d to mean "yes", just as if the
4026 input was not a terminal. Also avoid infinite loop if EOF
4027 occurs in mid-input-line before newline. This allows
4028 query to be used at EOF on stdin with reasonable results.
4030 * infrun.c (proceed): Set breakpoint_proceeded.
4032 * values.c (value_as_long): Avoid infinite recursion for enums.
4033 (_initialize_values): Fix typo in help msg (kingdon).
4035 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
4036 RL_LIB for linking. This allows -lreadline for linking
4037 and nothing for dependencies, once readline is a real library.
4039 * config.gdb: Jim Kingdon: give useful error message if the
4040 host or target type is not recognized.
4042 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
4043 it just defines it. Dumb, but deal with it.
4045 * Jim Kingdon suggests:
4046 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
4048 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
4050 * Makefile.dist (VERSION): Bump version # to 3.91.2.
4052 * Clean up Bothner's changes.
4054 * blockframe.c (clear_pc_function_cache): New function.
4055 * blockframe.c: remake cache_pc_function_* static.
4056 * dbxread.c (symbol_file_command): remove references to
4057 cache_pc_function_* variables.
4058 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
4059 * printcmd.c: Avoid kludging a global variable (addressprint)
4060 to avoid printing the address of a string twice. Instead,
4061 pass the format letter 's' down low enough that it can be seen
4062 to avoid this problem.
4063 (print_formatted): Pass format arg to value_print.
4064 (restore_addressprint): Remove function.
4065 (do_examine): Avoid hacking addressprint, cleanups and such.
4066 (print_frame_args): Add a comment to a Bothner change.
4067 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
4068 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
4069 to wipe out the values cached in blockframe.c.
4070 * symtab.c (find_method): Add comment saying how big you must
4071 allocate to be "big enough". Per being terse again.
4072 * valprint.c (val_print): Handle format letter "s" to print
4073 strings without addresses. Add comment to vtbl printing code
4074 which casts with wild abandon. Rearrange reference-printing
4076 @0xaddr: value (print w/addressprint)
4077 value (print w/~addressprint)
4078 @0xaddr (parameter lists w/addressprint)
4079 or nothing (parameter lists w/o addressprint)
4081 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
4083 * Merge more changes from Per Bothner:
4085 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
4086 annoying) that I tried to improve it. Here are my suggestions.
4088 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
4091 Do automatic de-reference when taking the address of a reference.
4093 Don't deref_ref when printing parameter lists.
4095 More attempts at treating refernences properly.
4097 In val_print, if deref_ref==0, don't print dangling " = ".
4099 Add COERCE_REF macro, which de-references an REF.
4101 * Merge changes from Per Bothner:
4103 * Fixed (Sony news)-specific configuration problems.
4104 * Fixed other problems with using vanilla pcc and libc (enum problems;
4105 assumption that vsprintf exists).
4106 * Some major speed-ups (finc_pc_partial_function now caches a match;
4107 parsing avoids duplicate symbol_lookup calls).
4108 * Changed handling of baseclasses (no longer use baseclasses field
4109 of struct type, use the first n_baseclasses fields instead).
4110 * Various minor changes/fixes, most C++-related.
4113 Cache the most previous match from find_pc_partial_function.
4114 (Save both low and high ends of matching function's pc range.)
4115 This speeds up the loop of infrun.c:wait_for_inferior quite
4116 a bit, and makes step/next commands much zippier.
4118 Added an enum->int cast (otherwise, some compilers barf).
4120 No longer set baseclass offset to 0, since multiple
4121 inheritance now mostly works.
4122 Added a number of casts, to shut up compiler warnings
4123 (after stabs where made enums, not ints).
4124 When discarding a symbol table (in symbol_file_command),
4125 must clear the cache introduced in blockframe.c.
4126 Don't convert $vtbl_ptr_type to vtbl any more.
4127 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
4128 Mask off sign bit emitted by g++ for virtual table offset.
4129 Set voffset to -1 (not 1) for static member functions.
4131 Changed parsing/lexing of names to avoid doing symbol lookup twice
4132 (once when lexing to determine symbol class, once for real).
4133 Now only call symbol_lookup once. Fields of 'this' win especially big.
4135 Subpress printing addr twice in the case of 'x/s addr'.
4137 lookup_basetype_type is no longer used.
4138 Add find_methods as recursive helper function to decode_line_1.
4139 This allows multiple inheritance to work.
4140 Also, once one or more matches has been found, do not look in
4141 base-classes. (Baseclass methods would be overridden, anyway.)
4143 Removed baseclasses array in struct type.
4144 Instead of using baseclasses[i], use fields[i-1].
4145 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
4146 Changed sign convention of voffset (previous was inconsistent).
4148 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4150 Used to assume existence of vsprintf. Re-written to not need it
4151 if HAVE_VPRINTF is undefined.
4153 typecmp was too pessimistic. Made it less so.
4155 Don't print space after address.
4156 If vtable points to a misc symbol (with 0 offset), print it,
4157 since that indicates the actual class of the object.
4158 Changed ype_print_derivation_info to use new inheritance
4159 scheme (without baseclasses vector).
4161 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4162 Also, changes needed because TYPE_BASECLASSES were removed.
4164 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4166 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4169 If there is no path set, and the symbols don't indicate what directory
4170 a file was compiled in, look in the current directory. But either
4171 a path or a known compilation directory will prevent this.
4174 Three independent bug fixes:
4175 * Remove the #if 0 block that breaks some stuff.
4176 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4177 adapt gdb to either SunOS 4.0.* or 4.1.
4178 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4181 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4184 (type_print) Demangle the name being printed.
4185 (type_print_base) Handle botched demangling without coredump (tiemann).
4188 (check_stub_method): Document routine.
4189 (tiemann) fix bug for no-arg functions
4190 Avoid clobbering beyond end of malloc'd storage.
4191 Terminate the argument list properly.
4193 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4195 * Changes merged by John Gilmore:
4198 In breakpoint_1, use new print_address_symbolic instead
4199 of find_pc_partial_function. (This forces use of assembler-level
4200 addresses, and avoids misleading non-mangled source-level names.)
4202 Generalize ansi argument such that -1 means skip arglist totally.
4203 Removed global variable print_ansi_qualifiers (which made
4204 code non-reentrant), in favor of extra explicit arguments
4205 to internal routines.
4207 Add new helper function print_address_symbolic.
4208 Use find_pc_misc_function instead of find_pc_partial_function
4209 (since we want assembler-level symbols here).
4211 Print unknown function as just "f (...)", not "f (...) (...)".
4212 Use new fputs_demangled explicitly.
4214 Fixed a typing violation (problem: value.h cannot be imported
4215 without renaming many variable in this file).
4216 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4217 decode_line_1: Moved forward some never-reached code.
4218 Made decode_line_2 skip function prologues correctly.
4220 fputs_filtered should not demangle by default.
4221 Add new fputs_demangled to demangle on demand..
4223 Change value_struct_elt to use value_primitive_field (using recursive
4224 utility function search_struct_field). This allows foo.bar to work
4225 for multiple inheritance (so far only for data fields).
4226 Change check_field in the same way (recursive helper function
4227 to support multiple inheritance).
4228 (Note: there are more of these problems that I haven't fixed.
4229 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4230 value_of_this: 'this' symbol name is now just "this", note "$this".
4232 Don't print static members.
4233 Avoid printing "members of <type>" if there are none.
4234 Simplified type_print_derivation_info by merging duplicate code.
4235 Remove useless blank lines in type_print_base (ptype command).
4237 Added declaration of new routine value_primitive_field.
4239 Added value_primitive_field which is generalized version of
4240 value_field that can handle multiple inheritance (non-zero offsets etc).
4241 Re-implemented value_field to call value_primitive_field.
4243 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
4245 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4246 delete the whole environment. Karl Berry reported the bug.
4247 * source.c - fix openp to avoid //'s in filenames, which
4248 trigger an Emacs bug causing it to not be able to find files
4249 when running gdb in a window.
4250 * dbxread.c - zap the #if 0 that botches the add-file code.
4251 It seems to work a lot better without all the code commented out.
4253 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
4255 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
4258 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
4260 * Makefile - added a ${CFLAGS} to a couple of entries,
4261 added remote-sa.sparc.c
4262 * added remote.sa-sparc.c, a modification of remote.c
4263 which conducts a dialog directly with the SparcStation prom.
4264 * breakpoint.c, infrun.c, sparcdep.c added
4265 remote_insert_breakpoint(), and remote_remove_breakpoint()
4266 to breakpoint.c instead of directly writing breakpoint instructions.
4267 * sparcdep.c on remote_debugging,there is no need
4268 to remove signle step breakpoint instructions.
4269 * main.c added "-epoch" flag and "int epoch_interface" to main.c
4271 * printcmd.c - epoch interface sends lisp expressions to open up
4272 epoch windows on inspection.
4273 * valprint.c - added arrayprint, and addressprint and made adding
4274 format controls easier
4275 * wait.h added a couple of undef's because we were getting
4276 complaints about WSTOPSIG and WTERMSIG begin redefined.
4279 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
4281 * symtab.c (decode_line_1): Add support for handling method stubs

4286 * values.c (baseclass_addr): Run loop from INDEX+1 to
4287 N_BASECLASSES; otherwise, we can still get into a loop.
4288 @@ This should be restructured to use a cleaner search strategy.
4290 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
4292 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
4293 abbreviation "Tt" for tags which have the same name as their
4296 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
4298 * symtab.c (list_symbols): add ability to set breakpoints on all
4299 the functions which match a particular regular expression.
4301 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
4303 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
4304 should print ANSI qualifiers (such as `const' and `volatile').
4305 All callers changed to call with ANSI == 1, except from
4306 `check_method_stub', which uses old-style syntax.
4308 * symseg.h (struct fn_field): Remove unneccessary `args' field.
4309 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
4311 * values.c (check_stub_method): New function.
4313 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
4315 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
4316 * valprint (type_print_base): Ditto.
4318 * symtab.c (gdb_mangle_typename): New function.
4320 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
4322 * breakpoint.c (catch_command): New function. Provides a
4323 mechanism to set breakpoints based on catch clauses.
4324 (disable_catch): Similar, but disables breakpoints on catch
4326 (delete_catch): Similar, but deleted breakpoints on catch clauses.
4328 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
4330 * blockframe.c (blockvector_for_pc): New function.
4331 * blockframe.c (block_for_pc): Changed to call
4332 `blockvector_for_pc' and get the block itself.
4334 * stack.c (catch_info): New function. Prints info about
4335 exceptions which can be caught in the current frame.
4336 * stack.c (print_frame_label_vars): New function. Similar to
4337 `print_frame_local_vars'.
4338 * stack.c (print_block_frame_labels): Prints out labels that are
4339 defined in this frame. These labels are exceptions that can be
4342 * dbxread.c: Updated to handle N_CATCH symtab types.
4344 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
4346 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
4347 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
4348 when printing the type.
4350 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
4352 * valprint.c (val_print): Use `baseclass_addr' to access the
4353 baseclasses pointed to via the derived class object at VALADDR.
4355 * values.c (baseclass_addr): New function. Casts derived pointers
4356 to baseclass pointers taking virtual baseclasses and multiple
4357 inheritance into account.
4359 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4363 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4365 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
4366 exp_valid_block field correctly.
4368 * infrun.c (wait_for_inferior): When checking "don't even think
4369 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
4370 also check step_resume_breakpoint.
4371 Insert breakpoints and continue (not step) if
4372 step_resume_break_address != NULL, even if another_trap.
4373 If trap_expected and we enter sigtramp, then set up a
4375 If trap_expected is set when we hit the step_resume_break,
4377 When calling resume and trap_expected says tell resume to step
4378 (2 places), also check step_resume_break_address.
4380 * infrun.c (wait_for_inferior): Don't set
4381 prev_{pc,sp,func_{start,name}} before calling wait ().
4382 Do set them after exiting loop.

4386 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4388 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
4389 Restore old code which distinguishes between trap_expected and
4390 running_in_shell, just make the latter take any non-TRAP signal,
4393 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
4395 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
4396 xconfig/3b1 (CC,PINSN_CC): Define.

4420 char. Add macro VALUE_OPTIMIZED_OUT.
4422 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
4423 instead of stuffing things in buffers (oappend, etc).

4456 findvar.c: Rewrite code which called find_saved_register to
4457 call get_saved_register instead.
4459 Sun Apr 22 14:47:51 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

4499 m-m88k.h: Use INIT_{FRAME_PC,EXTRA_FRAME_INFO} to do tdesc stuff.
4500 Use dummy versions of FRAME_CHAIN_*.
