1 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3 * breakpoint.c (insert_breakpoints): Restore warning about
4 the program might be running in another process, but only for
5 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
6 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
8 * utils.c (error): if error_pre_print is set, print the string
10 * main.c (main, print_gnu_advertisement, print_gdb_version):
11 Reformat legalese so it always prints, but acts as an "I'm here"
12 message while symbols are being read. If any errors occur,
13 print a few newlines to set off the message and start it at the
14 left margin. Remove mention of "help" command, and don't yak
16 (catch_errors): Error string is now printed first in case of
18 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
19 suggest the "help" command.
21 * Makefile.in (VERSION): Set to 4.0.2.
23 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
25 * .gdbinit: Remove useless "rr" command. Set complaints
26 to 1 for people debugging gdb.
28 * breakpoint.c, remote-vx.c: Reword strings printed by
31 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
33 * WHATS.NEW: "history write -> history save". Doc "write on/off".
34 (Fix from kenc@viewlogic.com.)
36 Fix some infrastructure to be able to cope with host and target
37 machines with different sized basic types (ints, ptrs, etc).
38 (Idea from pierre@la.tce.com (Pierre Willard).)
40 * values.c (value_from_longest): Rename from value_from_long.
41 Handle pointer types as well as integers, so that targets with
42 different pointer sizes from the host can be accomodated.
43 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
44 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
45 uses of value_from_long to value_from_longest.
46 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
47 the correct pointer type to value_from_long{est}.
49 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
51 * remote-vx.c: Remove obsolete code for calling functions via
52 vxworks kludge interface (it referenced value_from_long).
54 * valops.c (value_string): Find malloc with lookup_misc_func, not
57 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
59 Make writing to files work properly. (Fixes to BFD are also needed.)
61 * core.c (core_open): Open file ourselves, read or r/w, depending on
62 write_files. Use bfd_fdopenr.
63 * gdbcore.h (write_files): New variable.
64 * exec.c (write_files): Define variable, add set&show for it.
65 (exec_file_command): Use write_files to open for read or r/write.
67 Make shared library reading happen automatically. These changes
68 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
70 * inferior.h (stop_soon_quietly): Add to exported variables.
71 * infrun.c (child_create_inferior): call solib hook, if defined.
72 (child_attach): call solib hook, if defined.
73 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
74 (find_solib): Use lookup_misc_func rather than hand-rolled.
75 (symbol_add_stub): New stub for catch_errors.
76 (solib_add): Avoid output if !from_tty. Catch errors rather
77 than just calling symbol_file_add and bombing.
78 (solib_create_inferior_hook): Interface with the target process
79 to let it read and alloc shared libs, then figure out what it did.
81 * core.c (validate_files): Fix typo, soften warning.
82 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
84 * utils.c (fputs_demangled): Avoid duplicate printing if
85 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
87 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
88 (Fix from pierre@la.tce.com (Pierre Willard).)
90 * main.c (catch_errors): Change argument to a char * from an int,
91 since a char * can point to a struct full of glop, but an int
92 is not guaranteed to be able to hold a pointer.
93 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
94 breakpoint_re_set_one, breakpoint_re_set): Adapt.
95 * core.c (core_open, solib_add_stub): Adapt.
96 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
98 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
100 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
101 by adding .NOEXPORT target.
103 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
107 * Makefile.in (VERSION): Roll to 4.0.
108 (gdb.tar.Z): Make refcard.ps as well, for shipment.
110 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
112 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
115 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
118 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
120 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
121 reflect above name change
123 * WHATS.NEW: correct pointer to refcard.
125 * doc/gdb.texinfo: update New Features, Installing
127 * doc/gdbint.texinfo: add short description of configure +template
129 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
131 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
133 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
135 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
136 tar file, add dependencies for referenced doc files.
138 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
140 * coffread.c, symfile.c, stack.c: saberized.
142 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
144 * doc/refcard.tex: permuted Essential Commands sec
146 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
148 set/show symbol-reloading
149 default set complaints 0
151 RET-repeat disabled after prompted long displays
152 processID (attach) interpretation of 2nd GDB cmdline arg
154 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
156 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
157 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
158 breakpoint.c, main.c: lint.
160 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
162 Install new configuration scheme for GDB and friends.
164 * config.sub: Translate ordinary names to three-part names.
165 * configure: Use three-part names internally.
166 * configure.in: Translate three-part names to filenames.
168 * README, WHATS.NEW: Update for gdb-4.0.
169 * Makefile.in: Roll VERSION to 3.99.
171 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
173 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
174 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
175 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
176 to single structures rather than arrays; when passing
177 their address, use &. This avoids trouble with bdead compilers.
178 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
179 instead. This avoids portability headaches.
180 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
182 * source.c (open_source_file): Avoid ANSI const bdeath by
183 skipping declaration and then casting result value.
184 * tm-hp300bsd.h: Clarify comment.
185 * utils.c (strstr): Result is const char *; ANSI bdeath.
186 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
187 since system include file defines it differently from "defs.h",
188 though the two are equivalent for our purposes.
189 * tconfig/hp300bsd: Add m68k-tdep.o.
191 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
193 * tconfig/sun*4: Remove warnings about system assembler.
195 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
197 * mcheck.c: Avoid warning about undeclared abort fn.
198 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
199 it causes recursive calls to error() when used in cleanups.
200 To do so requires that we make it a function, so we do.
201 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
202 * utils.c (do_cleanups): Remove the current cleanup from the
203 chain *before* calling it, in case error() is called from it.
204 The result won't be pretty, but won't be an infinite loop either.
206 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
208 * dbxread.c (read_struct_type): Grok anon structs for C++.
209 (vb_name, vptr_name): Null terminate these strings.
211 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
213 Minor bug fixes from BSD Net2 gdb:
215 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
216 returns 0, there is no previous frame.
217 * breakpoint.c (commands_command): If !from_tty, don't call
218 input_from_terminal_p().
219 * dbxread.c (record_misc_function): Speed up slightly.
220 (compare_psymbols): Ditto.
221 * infcmd.c (do_registers_info): Take a second argument to
222 determine whether to print float registers. "info registers"
223 does not do so anymore. "info all-registers" does, now.
224 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
226 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
227 * inflow.c (initialize_inflow): Set tflags_ours correctly.
231 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
232 executing_breakpoint_commands if we are interrupted by error.
233 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
234 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
235 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
236 catch_errors() so we can setup the frame regardless of whether
237 the shared libs work.
238 * ieee-float.c (double_to_ieee_extended): Get exponent from
239 right place in little-endian systems. From John Carey.
241 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
243 * main.c: Remove unused terminating_signals and catch_termination().
244 (long_options): Terminate with a zero element.
245 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
246 (gdb_readline): Make call-compatible with readline.
247 (init_signals): Improve comments re vfork vs. signal.
249 * utils.c (prompt_for_continue): Use new gdb_readline().
250 If we prompt for continuation, we don't let CR repeat the previous
251 command, once we get back to a prompt. It's too easy to keep
252 hitting CR, expecting "--more--" prompts, and have some long
253 command start repeating on you.
255 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
257 * blockframe.c (frameless_look_for_prologue): Speed up by
258 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
259 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
260 Define two variants, one faster.
261 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
262 and return zero, rather than giving an error.
263 (setup_arbitrary_frame): Initialize the PC in the new frame.
264 (skip_prologue): Add a second arg saying whether we're just
265 checking for a frameless function or not.
267 * core.c (core_open, core_close, core_xfer_memory): Move
268 section table pointers and bfd* into the target_ops.
269 (core_open): Allow errors in shared lib reading, etc.
270 (core_files_info): Describe shared library sections.
272 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
273 exec_files_info, set_section_command): Move section table
274 pointers and bfd* into the target_ops.
275 (add_to_section_table): Add BFD to section table.
277 * target.c (target_xfer_memory, target_info): Pass target to
278 xfer_memory and target_info functions.
281 * gdbcore.h: Move struct section_table.
282 * target.h: New home of struct section_table.
284 * solib.c (solib_add): New argument is the target_ops whose
285 section list is to be added to, if any. Reallocate the
286 sections in that target to add any that come from shared libs.
287 (throughout) so_sections renamed to sections.
288 (solib_xfer_memory): Deleted.
289 * tm-sunos.h (SOLIB_ADD): Add target argument.
290 (SOLIB_XFER_MEMORY): Delete.
292 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
293 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
294 from target_ops. It's the same on all targets. Add two section
295 pointers to target_ops.
297 * stack.c (find_relative_frame): Dump ancient algorithm for
298 "down", just use handy "next" pointers.
299 (frame_command): Don't error if there is no stack; let user
302 * inflow.c (new_tty_prefork, new_tty): New prefork routine
303 modifies static state in the parent process; new_tty itself
304 runs in the child and modifies the child's file descriptors
305 to match the saved static state.
306 * infrun.c (child_create_inferior): Call new_tty_prefork,
309 * infptrace.c (child_xfer_memory): Add ignored target arg.
310 * remote-eb.c (eb_xfer_inferior_memory): ''
311 * remote-nindy.c (nindy_xfer_inferior_memory): ''
312 * remote-vx.c (vx_xfer_memory): ''
313 * remote.c (remote_xfer_memory): ''. Rename from
314 remote_xfer_inferior_memory.
316 * main.c (main): Only try to attach "corefile" argument if
317 it starts with a digit.
319 * symfile.c (symbol_reloading): New "set/show" variable.
320 (symbol_file_add): Shorten message about symbol reading.
321 (add_symbol_file_command): Merge with add_syms_addr_command,
322 since this should work on all targets now.
323 (stop_whining): Default to zero, to shut up complaints
324 about bad symbol tables on many systems.
325 (free_named_symtabs): Just exit unless symbol_reloading.
327 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
328 and add comment explaining shared library screw.
330 * source.c: #if defined => #ifdef.
332 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
334 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
336 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
338 * doc/rdl-apps.texinfo: provide default readline-appendix finder
339 (doc/Makefile knows how to make one for local config)
341 * Makefile.in: use doc/Makefile for doc targets
343 * doc/Makefile: GDB documentation now has its own Makefile
344 doc/refcard.tex: renamed from "gdbrc.tex"
345 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
346 doc/gdbint.texinfo: add markup in "Cleanups" chapter
349 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
351 * values.c (baseclass_addr): When reading target memory, use the
352 length of the basetype, not the upper type. We've only malloc'd
353 enough space for the basetype, leading to errors in free().
355 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
356 ends up as a function specially, since we know the actual type of
357 the pointed-to address. This (somewhat) fixes display of
358 expressions that include misc_function_vector names. Try `cond 1
359 !strcmp("a","b")' then `i b'.
361 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
362 The child can be proceeded from inside wait_for_inferior in
363 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
364 getting skipped in that case.
366 * expprint.c (print_subexp): Use filtered output, since the
367 subroutines we call use it, otherwise the output is horribly
368 mangled, since output of wrappable stuff comes out late.
370 * Makefile.in: Bump VERSION to 3.98.1
372 * infrun.c (child_create_process): Use execlp to find the
373 shell to exec our target program. This requires some fiddling
374 with `environ' since there is no execlpe().
376 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
378 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
379 Minor rearrangement of refcard permits two new make targets--
380 gdbrc.dvi DVI output for refcard, using CM fonts
381 gdbrc.ps PostScript refcard, using PS fonts
383 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
387 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
388 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
390 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
392 * doc/gdb.texinfo: last changes for release.
393 Minor typo and formatting fixes; incorporated most fixes remaining from
394 filed mail commenting on earlier drafts.
396 Added warnings: pipes don't work in run command;
397 conditions are converse of assertions;
398 step over fn without debug info goes to next fn;
399 vars may have "wrong" values near fn entrance, exit
401 Added example from Kingston on printing repeated nonadjacent values
403 Added explicit mention that in Emacs gdb mode C-c and C-z are like
404 shell mode for signals
406 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
407 doesn't sound so much like its parent "Stopping and Continuing"; also
408 moved entries on continue to top of section, so they don't get lost.
410 Improved installation directions in appendix, added manual formatting
413 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
415 * configure.in: Remove xm.h and tm.h even if we aren't linking
416 new ones, so "./configure sun4; ./configure none" does the right
417 thing. Assume that alldeps.mak and depend are already built in
418 srcdir, and avoid running "make" (particularly "make depend",
419 which involves "gcc") from inside configure. Build Makefile
420 directly rather than building Makefile.conf first.
421 * configure: Regenerate with above changes.
422 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
423 to 3.98. Revise gdb.tar.Z procedure to produce a file
424 called gdb-$(VERSION).tar.Z but which unpacks into a
425 directory called "gdb". Move non-source files out of
426 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
427 (depend): Don't try to do "gcc expread.y".
428 (expread.o): Update dependencies by hand.
430 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
433 Fixed a variety of small typos that prevented info from formatting
434 cleanly; altered too-long heading for GPL Appendix, as discussed
435 w/RMS; Changed date on cover to July 91.
437 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
440 (1) Applied some fixes due to comments from Larry Breed (easier ones
442 (2) Eliminated use of @footnote---had my doubts about it anyways, and
443 it's broken in latest texinfo
444 (3) Introduced *some* use of [] for optional arguments, where
445 explanation is not simpler by listing cmd w arg and cmd w/out arg
446 separately. Still not using @deffn.
447 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
448 couple of headings are too long. Need patches to texinfo or revision
451 * Partial update to README (which still needs work for this
452 release!): (1) use of configure corrected for new script,
453 (2) "make gdb.dvi" and "make gdb.info" mentioned.
455 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
457 * symtab.c (lookup_symbol): Don't complain right off about
458 no debug symbols; use the misc function vector first.
459 (list_symbols): Use misc function vector to find symbols
460 that don't have debug info, and print them.
461 (find_pc_symtab): Temporarily avoid fatal() when psymtab
462 PC range doesn't match symtab PC range, as it does on the
463 MIPS because our symtab reading isn't perfect.
465 * dbxread.c (dbx_symfile_read): Make warning about
466 "no debug symbols" slightly nicer.
468 * source.c (select_source_symtab): If "main" symbol exists,
469 but decode_line_spec can't find line info, don't just return
470 a zero; try other source symtabs or give an error.
472 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
473 their low addresses first, then rip through fixing high addrs.
475 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
477 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
479 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
481 * Minor, mostly mechanical, cleanup of doc subdir for clean
482 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
483 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
485 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
487 Mostly MIPS and general symbol-reading fixups.
489 * doc/gdbint.texinfo: Add documentation on symbol-reading
492 * mipsread.c: Remove kludges around #include "ecoff.h".
493 Remove redefinitions of a_magic, etc, no longer used.
494 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
495 Fix global overview comments to match symfile.c protocol.
496 (mipscoff_new_init): Eliminate cur_hdr if we have one.
497 (mipscoff_symfile_read): Eliminate unused code. Avoid
498 sorting all the symtabs, when all we have read here is psymtabs.
499 The symtabs are sorted as they are created anyway. Tell
500 condense_misc_bunches whether we're mainline.
501 (psymtab_to_symtab_1): Pass filename when recursing, to make
502 stack trace more informative.
503 (parse_partial_symbols): Assume cur_hdr as argument.
504 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
505 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
506 the TYPE_NAME of char *, since that's done in symfile.c.
507 (free_numargs, parse_symbol, add_symbol, add_block,
508 shrink_linetable): Declare these fns void.
509 (upgrade_type): Convert tree of if's to switch. Clean up
510 bogus "off == 0" handling with a complaint. Avoid setting
511 field bitpos and bitsize of array with lower and upper bounds.
512 Check specified bitsize of elements against their actual type's
513 bitsize, and complain if different. Complain about unknown
515 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
516 (psymtab_to_symtab_1): Print names of subsidiary files that
517 are being read in. FIXME, we read far too many files. This code
518 is not the problem, the problem is in parse_fdr where the psymtabs
520 (cross_ref): Result should indicate that we used one aux entry
521 normally, or two if we encountered a "next" entry. This used
522 to leave the caller pointing at the wrong aux entry.
523 (add_symbol): If overflowed cur_block, reallocate it larger,
524 chase all pointers to it, and complain(), rather than clobber memory.
525 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
526 (new_field): Only allocate one field initially, not two.
527 Pull ++ out of macro argument. Simplify.
528 (_initialize_mipsread): Avoid initialization of importd
529 global_psymbols and static_psymbols.
531 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
532 to properly set pst->symtab; avoid searching for it.
533 (symfile_fns): Improve comments, add a FIXME.
534 * dbxread.c: Update comments to reflect symfile protocol.
535 (read_ofile_symtab, end_symtab): Return the symtab.
536 (psymtab_to_symtab_1): Set pst->symtab.
538 * coffread.c (coff_symfile_read): tell condense_misc_bunches
539 whether we're mainline.
541 * symfile.h (sym_fns): Remove unused sym_discard member.
542 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
544 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
545 the environment variable is not.
546 * infcmd.c (finish_command): Use filtered printfs.
547 * cplus-dem.c: Add struct tags to a few unnamed structs.
548 * valops.c (value_coerce_array): Improve comments.
549 * valprint.c (type_print_varspec_suffix): Print array size only
550 if greater than zero.
551 * m88k-tdep.c: Shift some lines left by one space, that had
552 apparently been trashed at some point.
553 * TODO: More things to do, a few got done.
555 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
557 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
558 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
560 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
561 * expread.y, findvar.c, symmisc.c: Ditto.
562 * printcmd.c (address_info): Update printed forms of LOC_
563 symbols. Elim LOC_EXTERNAL.
564 (print_frame_args): Keep track of param stack offsets before
565 re-looking up to find the local register param is kept in.
567 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
568 Further integration of mipsread into gdb. Eliminate unused
569 routines, duplicate declarations. Handle static symbols in
570 psymtabs as well as external symbols. When reading symtabs,
571 insert symbols into the correct block (global, static, or a local
573 (read_mips_symtab, parse_partial_symbols): Don't pass useless
575 (mipscoff_symfile_read): Don't call select_source_symtab.
576 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
577 rather than SYMBOL_VALUE.
578 (parse_external): Comment clobbering of top_stack.
579 (parse_partial_symbols): Update comments. Allocate and parse
580 static symbols as well as external symbols. FIXME, enum values
581 are not handled in this pass, but should be. Inline new_psymbol.
582 Use SYMBOL_VALUE_ADDRESS.
583 (psymtab_to_symtab_1): Read symbols into global static block
584 by default (until enter some function's local block context).
585 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
586 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
588 * source.c (select_source_symtab): Select a source symtab
589 from either the symtabs or, failing that, the psymtabs.
590 (list_command): Update error message.
591 (forward_search_command, reverse_search_command): Use getc, not
592 fgetc, for speed. FIXME, add comment about buffers that die if
593 overrun by long line.
595 * values.c (unpack_field_as_long, modify_field): Avoid shifting
596 by an entire word, which is not portable, if we have a 32-bit
597 field. (Code in dbxread.c already turns such bitfields, if
598 aligned, into ordinary ints, but fixing this will help for other
599 symbol formats and for future changes.)
600 * core.c (core_open): Handle ANSI const brain death.
601 * utils.c (vprintf): Fix varargs typo.
603 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
605 * findvar.c (find_var_value): Handle &function better.
606 * TODO: Document work needed on &fn and &array.
607 * printcmd.c (print_address_symbolic): New arg is the prefix
608 to print if a name is printed.
609 (print_address_demangle): Honor "set print address" now.
610 Use new arg above to improve spacing of output.
611 * valprint.c (val_print): When printing function pointers,
612 print symbolic form too.
613 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
615 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
617 * core.c (memory_error): Reword error msg to mislead less.
619 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
621 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
622 parse_partial_symbols): Use newer BFD internals (external_filehdr
623 and external_aouthdr), byte-swap the fields that we care about
624 before using them, and make the file header data local to
625 read_the_mips_symtab rather than global.
627 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
629 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
630 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
632 * main.c (command_line_input): Flush stdout and stderr
633 before every call to readline. This reportedly fixes a bug
634 that comes up in Sys V running emacs-gdb and/or xxgdb,
635 when stdin/out are pipes or sockets.
637 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
639 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
640 Avoid declaring Makefile dependencies, because GNU Make stupidly
641 tries to update it if we do.
643 * coffread.c: Revise for minor changes to bfd internal coff
646 * configure: If -template= is given a relative path, make it
647 absolute before recurring in subdirectories.
649 * configure, configure.in, Makefile.in: Install "configure" script
650 as replacement for config.gdb.
651 * config.gdb, Makefile.dist, Makefile.sdir: Remove
652 * README: Update for configure, mostly. FIXME.
654 * Add dec3100 as equivalent to littlemips. Indicate in all host &
655 target config files that they are for the host. When the lines
656 get copied into the Makefile, this makes it more obvious what's
659 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
661 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
662 tabs, which end up in the disassembler output inadvertently.
664 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
666 Make it compile cleanly in an ANSI GCC2 environment.
668 * blockframe.c: <stdio.h>
669 * cplus-dem.c: free takes a void *, ifdef __STDC__
670 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
672 * defs.h (alloca): Avoid doing anything if alloca already def'd.
673 * stddef.h, stdlib.h: Remove these files.
674 * symtab.c: Avoid declaring qsort, close.
675 * symfile.c: Avoid declaring close.
676 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
677 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
679 Assorted other changes.
680 * dbxread.c: include "libaout.h", not "liba.out.h".
681 * printcmd.c (print_frame_args): Set recurse properly for
682 indentation of struct and array parameters.
683 * valops.c (value_cast): Allow cast to void.
684 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
685 single_step() in a target-independent fashion.
686 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
687 set up to be ready to continue. This makes us target independent.
688 * infptrace.c (child_resume): Remove call to single_step; now
689 can single step a SPARC target of any kind.
691 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
693 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
694 docn into separate sections---basically chapters, plus two loose
695 pieces that can be configured to go in different places. This
696 allows GNU m4 to preprocess the manual without coredumping.
698 * Makefile.dist: tell TeX where to find texinfo.
700 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
702 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
703 the new target "rdl-apps.texinfo" which captures the Makefile
704 variable that records where to find the Readline libraries.
706 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
708 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
709 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
710 * defs.h (const, volatile): Only define if not already defined.
711 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
713 * README: Update for release 3.95.
714 * config.gdb: Don't create readline dir in subdir builds.
715 * main.c: Include with "..." form for non-system include files,
716 so "gcc -MM" for "make depend" works.
717 Include readline files with "...h" rather than <readline/...h>.
718 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
720 * coffread.c: Undo minor damage done by Rich Pixley. Use
721 different internal and external representations of COFF
722 data structures. Use new BFD routines for swapping them in and
724 * symfile.c (free_named_symtabs): Avoid freeing file names that
725 are null or empty. Old i960 tools seem to produce files that
726 claim to have empty names, causing each successive file read
727 to blow away the previous one.
728 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
729 Move deferred_stores to top of file, but don't separate its
730 #define's from its variable. Add commentary.
731 * Makefile.dist: Fix Rich damage; undo "configure" changes in
732 favor of keeping the (working) config.gdb. Move readline
735 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
737 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
739 * infptrace.c (fetch_registers): no result, since now void.
740 * tconfig/news: target depends on m68k-tdep too.
742 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
744 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
747 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
748 applied various small fixes due to or inspired by RMS comments
750 * doc/gdb.texinfo: finished using all RMS comments, save those for
751 appendices on readline and cmd history (which are in other source
754 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
756 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
757 chapter 9; (2) documented 'break' command's menu mode for
758 overloaded names, in response to hgs problem report C++ p-31
760 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
762 * doc/gdb.texinfo: (1) better introductory example; (2) more
763 consistent use of @code, @samp, @file, @kbd throughout; small
764 cleanups to first three nodes; (3) new "Contributors" node;
765 (4) Appendix, Renamed Commands; (5) divert specialized startup
766 instructions to "Targets" chapter for generic manuals, while
767 leaving them up front for manuals specific to specialized
768 environments; (6) apply fixes from RMS comments through chapter 4.
770 * pretex.m4: modify explanatory text slightly (and redefine
771 "regexp") to keep GNU m4 from complaining. (It still crashes
772 later, but one step at a time...)
774 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
776 * readline/readline.c (update_line): Avoid dereferencing a pointer
777 before comparing it to its bounds. Saber caught this.
778 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
779 and only set PC if tgetstr returned non-null. Saber caught this.
781 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
783 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
784 stuff for config manual) here where it counts; updated
785 to use new subdir structure (gdb/doc/).
787 * Makefile: generated from above via
791 * gdbint.texinfo: added instructions on generating gdb.info* files
792 locally for release. These are ordinary info
793 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
794 Makefile)---but due to use of texinfo 2, can't count on makeinfo
795 to generate these, so we distribute them already formatted.
797 * gdb.texinfo: included full Info node and menu crud (as generated
798 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
800 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
801 put in comments-for-future gdb.info target (one day makeinfo will
804 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
806 * gdb.texinfo: Updated to include new or old undocumented
807 commands, at least the following (perhaps some others I forgot to
808 record): info f, info float, info path, info program, info s, info
809 set, info source, info terminal, info types, info user, set/show
811 Also covered all recent GDB command renames for v4.
813 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
815 * mipsread.c: Rather than keeping count of how many symtabs
816 and psymtabs we have, for sorting purposes, count them when
817 we need to sort. This fixes bug in rereading of symbol tables.
819 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
821 * infcmd.c: renamed "info path" to "show paths"
822 * gdbrc.tex: documented above.

831 * Makefile.dist: Roll VERSION to 3.95.
832 Fix up "saber_gdb" to work again.
833 * saber.suppress: Update.
835 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
836 symtab.h, target.c, target.h: Lint.
837 * core.c: setup and select frame after reading shared libs,
838 else reading shared libs will clobber them. Lint.
839 * utils.c (error): Force out any buffered wrap text.
841 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
843 * remote.c: Remove decls of memory_insert_breakpoint
844 and memory_remove_breakpoint, no longer used. (Suggestion of
847 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
848 to make it easier to interface to "configure"'d libraries.
850 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
852 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
853 aliases for set/show print.
855 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

910 coff_symfile_read to find_linenos and make it work with BFD.
912 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
914 * signame.c: Cast const char* to char* when assigning to sys_siglist.
916 * utils.c (strsave): Make arg const char* not char*.
918 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use
919 bpstat_explains_signal (stop_bpstat) not stop_breakpoint.
921 * tm-88k.h (START_INFERIOR_HOOK): Make tdesc_handle a dc_handle_t.
923 * tm-88k.h (EXTRACT_RETURN_VALUE): Use char * not void *.
925 * findvar.c (read_var_value, case LOC_CONST_BYTES): Put the address
926 in a char *, not a CORE_ADDR. Use SYMBOL_VALUE_BYTES.

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

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

977 symtab.c, cplus-dem.c, value.h, expread.y, valprint.c,
978 copying.awk, solib.c, inflow.c, symmisc.c
979 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
980 Use {value_as,unpack}_pointer (added to values.c)

985 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.
987 * tm-sparc.h: Remove GET_RWINDOW_REG.
988 (FRAME_CHAIN): Call sparc_frame_chain.
989 sparc-tdep.c (sparc_frame_chain): New function.
990 tm-sparc.h (EXTRACT_STRUCT_VALUE_ADDRESS): call
991 sparc_extract_struct_value_address (added to sparc-tdep.c).
993 * xm-sun386.h: Don't define SET_STACK_LIMIT_HUGE.
995 Tue Apr 30 13:13:33 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
997 * valprint.c (type_print_base): If the type being printed is a
998 struct containing undefined types, print "<undefine type>"
999 as the type instead of crashing.

1468 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1470 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1471 for printing the float info is host-dependent, not
1472 target-dependent. FIXME.
1473 * i386-pinsn.c: Move #includes to top, remove useless ones.
1474 * i386-tdep.c: Don't bother including <.../reg.h> since we
1475 don't use it (and it doesn't exist on host systems).
1477 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1478 Convert negative numbers properly.
1479 (ieee_test): Make numbers really random; fix format arg.
1481 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1482 * core.c (core_detach): Unpush core_ops, which might not be on
1483 top. We used to just pop the top, which broke things. Don't
1484 need dont_repeat() any more.
1485 (core_file_command): Psst! Don't repeat it.
1486 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1487 * expprint.c (print_subexp): Avoid switch fallthru on
1488 BINOP_ASSIGN_MODIFY, so we can print += and such.
1489 * frame.h: Fix typo.
1490 * inflow.c (kill_command): After killing inferior, print our
1491 current frame in the core file, if we have one.
1492 (generic_mourn_inferior): When inferior dies, either select
1493 the current frame (in the new target, e.g. core file), or
1494 set both the current and selected frames to NULL.
1496 Changes from Peter Schauer.
1498 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1500 * Make all file names fit in 14 characters (sigh and damn!):
1501 mv hp300hpux-xdep.c hp300ux-xdep.c
1502 mv symmetry-xdep.c symm-xdep.c
1503 mv symmetry-tdep.c symm-tdep.c
1504 mv convex-opcode.h convx-opcode.h
1505 mv tm-vxworks960.h tm-vx960.h
1506 mv tm-vxworks68.h tm-vx68.h
1507 mv Makefile.srcdir Makefile.sdir
1508 mv gdb-int.texinfo gdbint.texinfo
1509 mv remote-sa.m68k.shar rem-m68k.shar
1510 mv remote-multi.shar rem-multi.shar
1511 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1512 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1513 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1516 * command.c (user_info_1, user_info): New command for listing
1517 the user-defined commands.
1519 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1521 * dbxread.c (really_free_pendings): Clear file_symbols
1522 and global_symbols after freeing them; otherwise, running
1523 this function twice (if it appears twice on the cleanup
1524 chain), we try to free things twice.
1526 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1527 based on text_addr (the address of text in core), not on addr (the
1528 offset between text in the .o file and in core). This change
1529 is from Peter Schauer.
1531 * main.c: Define ALL_CLEANUPS as a cast of zero.
1532 (return_to_top_level): Use it.
1533 (main): Do all cleanups after each command run as part
1534 of the gdb startup sequence. Also do all cleanups before
1535 entering the command loop, and every time we exit the command
1536 loop and reenter. Before, the cleanups from the startup sequence
1537 were being left undone until the first error!
1538 (command_loop): Rename do_nothing cleanup to command_loop_marker
1539 so we can see it easily when examining the cleanup chain.
1540 (init_signals): Add another do_nothing for signal handling.
1541 (quit_command): Only try to kill target if it has execution.
1542 Problems in the target stack got us into a state where
1543 inferior_pid was nonzero but none of the targets had execution.
1544 In this state you couldn't exit gdb.
1546 * dbxread.c: Two changes from Peter Schauer.
1547 (echo_command): Fflush output after an echo command.
1548 (show_history): Pass all args to cmd_show_list.
1550 * utils.c (init_malloc): Call mtrace to turn on tracing
1551 if the environment variable MALLOC_TRACE is set to a file name.
1552 * mtrace.c: Add source file which provides a log of every malloc,
1553 free, and realloc to a trace file.
1554 * mtrace.awk: Add source file which analyzes the trace file.
1555 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1556 (VERSION): Roll to 3.94.3.
1558 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1559 (check_duplicates): Don't bother with watchpoints.
1560 (set_raw_breakpoint): Comment about danger of this routine.
1561 (watch_command): Parse and eval all args before calling
1564 * solib.c (find_solib): Avoid error in referencing memory to
1565 see if any more shared libraries have been added. This is
1566 particularly useful if the target has terminated. Bug reported
1569 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1570 in bringing up 3.94.2 on the Sun-3.
1572 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1573 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1574 expression (in scope) before reenabling watchpoint.
1575 * signame.c (init_sigs): Add missing declaration of i, fix
1576 sys_siglist declaration.
1577 * source.c (list_command): Fixed range computation to use
1579 * stack.c (backtrace_command): Do not allow command if target has
1580 no stack, print informative error message.
1581 * target.c (target_command): Do not write into command line
1582 because this fails if the target command is used in a user defined
1583 command. [This change was enhanced by gnu to support any-
1584 unique-prefix matching on target names.]
1585 * valops.c (value_struct_elt): Avoid infinite loop on an
1586 erroneous attempt to print the member of function (try p main.p).
1588 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1590 * expread.y (name_no_typename): Avoid reduce/reduce errors
1591 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1592 Since the GDB parser really doesn't use name_no_typename in a
1593 name-only context, the parser can't tell the diff between
1594 names and numbers here. Avoid allowing a name_no_typename
1595 to be a NAME_OR_*INT to resolve the conflict.
1597 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1599 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1601 * valprint.c (val_print_fields): bitfield printing didn't handle
1602 byte order. Indirect through a few more fns to cope.
1604 * values.c (modify_field): also cope with byte order.
1606 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1608 Cleanup for release 3.94.2:
1610 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1611 include files. Roll version to 3.94.2.
1613 * coffread.c (init_stringtab): Read length into unsigned char
1614 array before swapping; don't assume 32-bit longs.
1616 * target.c (target_info): Don't bother with get_sym_file, just use
1617 the symfile global variable.
1618 * symtab.h, symfile.c (get_sym_file): Delete it.
1620 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1621 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1622 (read_type): Replace one more error() with complain().
1624 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1626 * i960-tdep.c: Fix copyright attribution.
1628 * config.gdb: Quote all backquotes in doublequotes. You can
1629 quote me on that. BSD 4.4 shell found this one.
1631 * infptrace.c (throughout): The third argument to ptrace is an
1634 * infrun.c (wait_for_inferior): When program has terminated, we
1635 have to call target_terminal_ours before we pop that target off
1636 the stack (e.g. before a call to target_kill or
1637 target_mourn_inferior). This fixes problem where a program
1638 terminates, then GDB stops for (tty output) and you have to type
1639 "fg" to the shell to resume it. FIXME: This code for what to
1640 do after termination really should be in normal_stop instead.
1642 * gdbcore.h (read_memory_check): Change declaration; it changed
1645 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1646 4.4 prereleases, this avoids a bug in their sgtty compatability
1648 * remote.c: Use terminal.h rather than hand-rolling the same.
1650 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1651 * utils.c (strsave, strstr): Fix arg types.
1652 * valprint.c (val_print): lint
1654 MIPS symbol table support from Per Bothner:
1656 * symfile.c (symtab_fns): Remove initializer table that needs to
1657 be hacked for each new symbol file format supported.
1658 (add_symtab_fns): New function, chains symbol table
1659 handlers into the global list.
1660 (symfile_init): Search this list.
1661 * symfile.h: Add next pointer, declare add_symtab_fns.
1662 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1663 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1665 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1666 symbol *). Thus, we no longer need the hack to trash
1667 pst->filename. Good, since that hack confused code in symfile.c!
1669 (reorder_symtabs, destroy_all_symtabs): Removed static
1670 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1671 Instead, the latter now uses a temporary array (stack-allocated
1672 from an obstack, and then freed).
1674 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1675 haven't been set in the outermost stBlock of a procedure. This was
1676 a problem with f77 binaries on Ultrix 4.?.
1678 (new_symtab, new_symbol, new_type): Continue changing code to use
1679 obstacks more and otherwise conform to dbxread internal style.
1680 Made the free_code of symtabs be free_linetable (as in dbxread)
1681 instead of free_contents. This implies memory leaks when reading
1682 a new symbol table, until the conversion is finished. Did change
1683 (struct symbol) and (struct type) to be allocated on the
1684 symbol_obstack. Blocks and blockvectors are among the things
1687 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1688 tested much, but it solved one problem (reported by Meissner), and
1689 cleans up some other things. The problem happened when an
1690 included file contains actual code (functions) and not just
1691 definitions. The mips coff is a little inconvenient there, since
1692 it may cause a procedure to be mapped to the wrong psymtab.
1694 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1695 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1696 this will need work for the new core paradigm.
1698 Opcode patches from the net:
1700 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1701 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1702 missing altogether - they are added here. From Bruce Bauman.
1703 * mips-opcode.h: The low mask for C0 instructions was too small.
1704 From Garrett Lau. I modified the fix to check the entire 32-bit
1707 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1710 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1712 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1714 * dbxread.c (read_type): Pointer subtraction (value_sub in
1715 valarith.c) sometimes failed because the types of the
1716 pointers being subtracted were not identical.
1717 These differed because dbxread.c was allocating pointer types
1718 using dbx_alloc_type+smash_to_pointer_type instead of
1719 lookup_pointer_type. I failed to find a justification for the
1720 former, so I changed it to use the latter. Similarly, I
1721 replaced smash_to_function_type by lookup_function_type,
1722 and smash_to_reference_type by lookup_reference_type.
1724 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1725 _initialize_mipsread): corresponding changes.
1727 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1729 * source.c (mod_path): Do tilde_expand on each component of the path,
1730 rather than on the (list of) paths as a whole.
1731 (print_source_lines): Set first_line_listed in addition to
1732 current_source_symtab and current_source_line. If the source was
1733 not findable, after a "dir" command to fix the problem,
1734 a "list" would get the wrong lines.
1736 While I was there... (gnu):
1738 * dbxread.c (read_type): Change error to complaint.
1740 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1742 First attempt at detailed understanding of symbol table memory alloc.
1744 * dbxread.c (dbx_symfile_read): Free our string table if we
1745 aren't the mainline. Free the "info" struct since we're done with
1747 (init_psymbol_list): Free any previously allocated psymbol lists.
1748 (): FIXME: Should realloc-down the psymbol lists when done reading
1749 the main symbol file?
1751 * symmisc.c (free_symtab): Free fullname field too.
1753 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1754 (REGISTER_ADDR): Make result type unsigned int.
1756 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1757 define REGEX must also define REGEX1 (its dependency).
1759 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1761 * tconfig/i960: No longer works, points you at vxworks960 or
1764 * xgdb.c, XGDB-README: Remove file. Users can get the much
1766 * Makefile.dist: Remove all trace of xgdb.
1768 * breakpoint.c (breakpoint_1): Pass demangle arg to
1769 print_address_symbolic.
1770 (clear_breakpoints): Remove unused function.
1771 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1772 (breakpoint_re_set): Use catch_errors to do them all anyway.
1774 * gdb-int.texinfo (Host versus Target): Add section on what is
1775 a "host" feature versus what is a "target" feature.
1777 * infcmd.c (path_command, path_info): Handle the PATH variable
1778 (object search path) as conveniently as the source search path.
1779 * environ.c (set_in_environ): Set some vars in GDB's environment,
1780 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1781 * source.c (mod_path): New function, from guts of
1782 directory_command, modifies a path. Used by path_command.
1783 (directory_command): Call it.
1784 * defs.h (strsave): Declare.
1786 * utils.c (sevenbit_strings): Add new printing option.
1787 (printchar): Use it.
1788 (strsave): Provide this handy helper routine.
1789 (set_width_command): Rename set_screen_width_command.
1790 (_initialize_utils): "set screen-width" => "set width";
1791 "set screen-height" => "set height"; add sevenbit-strings.
1793 * infcmd.c (do_registers_info): Print floating point registers
1794 in raw hex as well as float format, regardless of whether it is
1795 a "virtual" convertible register.
1796 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1797 regs as a double, just in case it's being used that way.
1798 * values.c (unpack_long): Comment on array/function coercion.
1799 (unpack_double): Argument is in target byte order now. For
1800 integer arguments, just call unpack_long and float the result.
1801 * m68k-tdep.c: include defs.h for "const" handling.
1802 * remote-nindy.c: Use ieee-float stuff.
1803 (nindy_fetch_registers): Unpack double regs to host double, then
1805 (nindy_store_registers): Pack extendeds to host double, flip
1806 around by misusing unpack_double, send as target double.
1808 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1809 zero, as when stopped at the first instruction of a process.
1811 * blockframe.c: Fix filename in comment (param.h => tm.h).
1812 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1813 * tm-68k.h: Fix typos.
1815 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1817 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1819 * coredep.c (fetch_core_registers): Pass end-address of register
1820 section to register_addr as expected. Don't call supply_register
1821 if we'd just pass it garbage.
1823 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1825 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1827 * target.c (push_target, target_info): Cast enums to int for < or
1830 * stack.c (print_frame_info): Identify source file & line
1831 even if we can't print it.
1833 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1835 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1837 Clean up IEEE floating point support.
1839 * ieee-float.h: New file.
1840 * ieee-float.c: Write real routines to convert between host
1841 doubles and various target IEEE extendeds.
1842 * m68k-xdep.c: Eliminate assembler code for extended floats.
1843 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1844 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1845 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1846 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1847 double_to_ieee_extended.
1848 * i960-tdep.c: Define ext_format_i960.
1849 * m68k-tdep.c: Define ext_format_68881.
1850 * sparc-tdep.c: Define ext_format_sparc, though unused.
1851 * Makefile.dist (HFILES): Add ieee-float.h.
1852 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1855 Obsolete the "coffstrip" program in favor of using BFD's strip.
1857 * nindy-share/coffstrip.c: Remove file.
1858 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1859 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1860 * tconfig/nindy960: Remove reference to coffstrip.o.
1862 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1864 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1866 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1867 * dbxread.c: Remove static symfile_bfd.
1868 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1870 * inftarg.c (child_detach): Pop the child_ops vector if the
1871 detach is successful.
1872 * remote-nindy.c (nindy_create_inferior): Don't push a new
1873 nindy_ops since nindy uses the same one for execution and memory
1875 * core.c (core_ops): Use child_attach and child_create_inferior
1876 rather than default attach and create_inferior functions.
1878 Handle floating point registers in core files.
1880 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1881 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1882 This version untested since BFD doesn't yet support sun3 core
1884 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1885 conventions. Fix comments and style. This version has not
1886 been compiled yet, since we have no HP inhouse.
1887 * core.c (get_core_registers): Look for two sections, ".reg"
1888 and ".reg2", and pass both to fetch_core_registers sequentially.
1890 Revise directory path yet again.
1892 * source.c (forget_cached_source_info): Not static any more.
1893 (init_source_path): New default source path is "$cdir:$cwd".
1894 (dir_command): Handle variable arguments ($cdir, $cwd).
1895 (source_info): Print "Compilation directory" rather than
1896 "Originally compiled in" to remind people of $cdir.
1897 (openp): If the path contains $cwd, use current directory.
1898 (open_source_file): If compilation directory is known, replace
1899 first $cdir in path with the compilation directory.
1900 (print_source_lines): Even if we can't print the lines, set the
1901 current symtab and line for future commands like "info source" or
1902 "breakpoint". Also, error message now contains the file name,
1903 line number, and file access error message.
1904 (_initialize_source): Fix help text to describe changes.
1905 * main.c (cd_command): Forget cached source info when we chdir.
1906 * utils.c (strstr): Add simple implementation.
1908 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1910 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1911 Byte-swap COFF symbol tables if necessary when reading them in.
1912 Use complain() to replace error message in one spot. Needs
1913 corresponding change in bfd/coff-code.h to make some symbol
1914 swapping routines non-static.
1916 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1918 Merge changes from Eirik Fuller, for UTek.
1920 * defs.h (errno): Add declaration.
1921 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
1922 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1923 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1924 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
1925 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
1926 declarations of errno.
1928 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1930 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1931 <rpc/rpc.h> and <rpc/types.h>.
1933 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1935 * i960-tdep.c (examine_prologue): Add new argument limit,
1936 which stops the scan at the end of the prologue, or at the PC.
1937 This fixes a problem where it walks down into the code for the
1938 user's statements if that code looks like function prologues.
1939 Mark Fox and I have been bouncing this code back and forth, making
1940 small changes to it. Callers changed to match.
1942 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1944 Cleanup for gdb-3.94 release final:
1946 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1947 the .c files from vx-share and nindy-share, from the various
1948 macros, since they are not found via ALLDEPFILES.
1949 (SFILES): Add tm-i960.h.
1950 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1951 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1953 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1954 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
1956 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
1958 * am29k-tdep.c: Add contribution line.
1959 (examine_prologue): Cache information about function prologues in
1960 the misc-function-vector to avoid lots of references over the
1961 serial line while examining instructions.
1963 * core.c (core_close): New function made from cleanup_core.
1965 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1966 remote-vx.c, remote.c, target.c, target.h,
1967 Update target_ops vector to add attach, close, and load entries.
1968 Use add_syms_addr_command, not add_file_addr_command, for
1969 add_file. Break out close routine from existing code.
1971 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1972 they are in an obstack.
1973 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1975 (define_symbol): Add symbol type parameter; change callers;
1976 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1977 it to influence the symbol class on the i960.
1978 (define_symbol): Swap LOC_CONST's into target byte order.
1980 * exec.c (exec_close): New function.
1981 (exec_file_command): Call it.
1983 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1984 Fix byte order of frame pointer.
1985 (read_var_value): Result of 0 if var's value can't be found,
1986 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1987 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1988 (locate_var_value): Use read_var_value and use its lazy address
1989 as the location of the var's value. Lint.
1991 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1994 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1995 obsolete Intel versions in favor of vxgdb versions.
1996 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1997 code dealing with byte order of values, which Intel did in host byte
1998 order rather than gdb-4's target byte order.
1999 (i960_frame_chain_valid): Move to nindy-tdep.c.
2000 (examine_prologue, skip_prologue, frame_find_saved_regs,
2001 frame_args_address, leafproc_return, saved_pc_after_call,
2002 pop_frame): Add vxgdb versions from Mark Fox.
2003 (examine_prologue, frame_struct_result_address): Add code
2004 to deal with the saved value of G13 (struct return address
2006 (frame_args_address): Modify Mark's version to prefer the
2007 saved value over the current value in the topmost frame.
2008 Cache result in the frame info to avoid performance hair in
2010 (print_fault): Add gdb960 code for printing faults.
2011 (_initialize_i960): Actually call check_host.
2013 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
2014 add stub routines. FIXME, these currently just return zero!
2016 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
2017 (attach_command): Call target_attach, not target_open, now.
2019 * infrun.c (normal_stop): Make global, not static, for vx_attach.
2020 (child_attach): Rename from child_open.
2021 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
2022 don't confuse it with a zero step_resume_break_address.
2024 * inftarg.c (child_detach): Eliminate inferior_pid test.
2025 (child_files_info): Clean up message a bit.
2026 (child_ops): Use child_attach, not child_open, to attach.
2028 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
2029 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
2030 findvar.c to here, since it depends on the contents of the
2031 shadow_contents of breakpoints, but keep if #if 0 since it is
2034 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
2037 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
2038 (ptype_command, display_command): Eliminate have_inferior_p and
2039 have_core_file_p in favor of target_has_stack or
2040 target_has_execution.
2041 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
2042 code for actually finding the values of arguments, though we still
2043 keep track of the maximum stack offset for use in printing unnamed
2044 arguments. Handle missing FRAME_ARGS_ADDRESS.
2046 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
2047 (struct nindy_regs): Define registers passed to/from nindy.
2048 (nindy_fetch_registers, nindy_store-registers): Translate between
2049 nindy and GDB formats for the registers.
2050 (dcache_init): Statically allocate the cache, since it was being
2051 allocated by a malloc that was never freed anyway.
2052 (nindy_create_inferior): Error, not core dump, if no exec file.
2053 (nindy_before_main_loop): Use target_load, not target_add_file.
2055 * remote-vx.c (net_load): Specify large timeout for load
2056 requests. Allow user to break out with INTERRUPT.
2057 (net_break): Remove useless code, clean up. Change callers.
2058 (parse-args, skip_white_space, find_white_space): Clean up arg
2059 parsing to cope with quoted strings.
2060 (net_wait, net_quit): Never call error, just return status.
2061 (vx_read_register, vx_write_register): Cleanup status checking.
2062 #ifdef the code based on which CPU we are using (960 or 68k),
2063 FIXME, this should be completely general but it isn't yet.
2064 (vx_xfer_memory, vx_resume): Cleanup status checking.
2065 (vx_run_files_info): Improve message.
2066 (vx_load_command): Renamed from vx_add_file_command. Allow load
2068 (net_ptrace): Remove unused routine.
2069 (vx_wait): Adopt code from vxgdb960 to cope with broken
2070 connections to target machine and prompt to disconnect. Remove
2071 debug printouts. Map some EVENT_'s to SIGnals.
2072 (add_symbol_stub, vx_open): Print names of object files we found,
2073 and "ok" if we read their symbols OK. Clarify output in general.
2074 (vx_attach, vx_detach, vx_kill): Add these commands.
2075 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
2076 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
2077 "info files" output, and create_inferior, since we already have
2080 * stack.c (frame_info): Replace Frame_unknown with 0.
2081 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
2082 (return_command): Pop until the PC matches as well as the FP,
2083 so it works even if the FP is shared with another function,
2084 as in "frameless" or "leaf" procedures.
2086 * symfile.c (load_command): renamed from add_file_target_command.
2087 (add_syms_addr_command): renamed from add_file_addr_command.
2088 (add_syms_command): Stub to call target_add_syms.
2089 (_initialize_symfile): Change command names and descriptions,
2090 add-file => add-syms, and load from alias to its own command.
2092 * target.c (kill_or_be_killed, maybe_kill_then_attach,
2093 maybe_kill_then_create_inferior): Default for attempts to start
2094 a process, if one is already running, is to ask about killing
2095 it and retry if yes.
2096 (upstack_create_inferior): #if-0 it, strata obsolete it.
2097 (push_target, unpush_target, pop_target): to_close() a target
2098 before unstacking it.
2099 (target_info): Renamed from target_files_info.
2100 (_initialize_targets): Rename "i files" as "i target", accessible
2103 * target.h: Improve comments about the target_ vectored routines.
2105 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
2106 Convert commenting style to standard GNU style.
2107 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
2108 (SKIP_PROLOGUE): No longer a no-op.
2109 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
2110 (*_REGNUM): Sort register numbers.
2111 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
2112 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
2113 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
2114 are now 10 byte extendeds, not 8 byte doubles.
2115 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
2116 for nindy versus vxworks targets. FIXME, this should possibly go
2117 in the target vector.
2118 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
2119 frame_saved_regs and arg pointer with each frame.
2120 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
2121 (FRAME_ARGS_ADDRESS): Use cached result.
2122 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
2123 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
2124 (PRINT_RAMDON_SIGNAL): Call print_fault.
2125 (POP_FRAME): Now works.
2127 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
2128 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
2129 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
2130 (ADDITIONAL_OPTION_HANDLER): use target_load, not
2133 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
2134 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
2136 * valarith.c (value_subscripted_rvalue): Avoid handling
2137 floats and doubles specially; it gave alignment errors. Lint.
2139 * valops.c (value_of_variable, value_of_this): Error if unknown
2142 * valprint.c (print_floating): Bcopy rather than pointer-deref,
2143 to avoid alignment problems.
2144 (value_print): Handle unknown value address.
2145 (cplus_val_print): Two args are ignored; remove them. Change caller.
2146 (val_print): Use unpack_long rather than pointer-deref.
2149 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
2150 to avoid alignment problems.
2151 (value_being_returned): Error if return value unknown.
2152 (set_return_value): Add bogosity warning, FIXME. *
2154 * TODO: A woman's work is never done.
2156 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
2157 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
2158 Add ieee-float.o to OBS.
2159 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
2160 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
2161 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
2163 Changes to generalize the VxWorks RPC protocol slightly, to handle
2164 i960 as well as 68000.
2166 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
2167 * vx-share/reg.h: Produce i960 regs #ifdef I80960
2168 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
2169 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
2170 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
2171 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
2172 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
2173 so they will move in target byte order rather than network
2174 byte order (happens to be the same).
2176 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2178 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
2180 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2183 Add contribution lines to various files, showing where they
2186 * breakpoint.c (break_insn, check_break_insn_size,
2187 read_memory_nobpt): Remove to mem-break.c.
2189 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
2192 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
2193 entry has bad register number. This change is not
2194 tested in this release, FIXME.
2196 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
2199 * value.h: Force value's contents field to be aligned to hold
2200 at least a double or a long long (if supported). This avoids
2201 doing bcopy's in and out of the contents field.
2203 (step_1): Avoid coredump under obscure circumstances when we
2206 * symtab.h (misc_info): Add field to misc function vector for
2207 any kind of cached information the target code desires. AMD
2208 29000 uses this to avoid repeating examine_function_prologue's.
2210 * coffread.c: Lint. Remove static symfile, read_section_header.
2211 core.c (have_core_file_p): Lint: remove.
2212 expprint.c (print_subexp): Lint.
2213 infptrace.c, valops.c, valprint.c: lint.
2215 Roll in changes from vxgdb-5.0.1:
2217 * symtab.h: Comment byte order of each address class. Add
2218 LOC_LOCAL_ARG for frame-relative args (960).
2219 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
2220 symtab.c, symmisc.c: ditto.
2222 * infrun.c (init_wait_for_inferior): Clear stop_signal.
2224 * remote.c (remote_resume): Error if resume with a signal.
2226 * symfile.c (prim_record_misc_function): Clear misc_info.
2227 (fill_in_vptr_fieldno): Check stub type of arg.
2229 * valops.c (value_cast): Avoid looking up names of types whose
2230 name we don't know, to prevent coredump. Sun CC produces typedef
2231 rtx and the name of *rtx is zero...
2233 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2235 Roll in changes from final AMD 29000 port (Tiemann).
2237 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
2238 for ../include/a.out.encap.h. This might not work now that BFD
2239 is separately compiled. Instead, BFD support for encap will have
2240 to translate machine type 29k into the right COFF_MAGIC.
2242 * infcmd.c: Remove references to inferior_pid that aren't used
2243 in actual ptrace calls; use target_has_execution, etc.
2244 (have_inferior_p): Remove function.
2245 (program_info): Print target info rather than "process number";
2246 avoid gratuitous messages unless from_tty.
2247 (run_stack_dummy, finish_command): Set proceed_to_finish.
2248 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
2249 main.c: Lint. Lose have_inferior_p().
2250 inferior.h (have_inferior_p): Remove, lint.
2251 (proceed_to_finish): Add flag to ask that all regs be saved
2252 by normal_stop, for the few commands that need it, speeding up
2253 serial I/O. Add comments to stop_registers.
2255 * remote-eb.c: Remove newline from breakpoint message we grep
2256 for. Never time out when running the user program.
2260 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2262 Roll in changes from vxgdb-5.0.1:
2264 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
2265 symbol in its raw form, we are processing an unlinked ".o" file.
2266 See if the target environment has assigned it an address, using
2267 target_lookup_symbol (VxWorks does), and enter it into the symtab
2270 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
2271 68k versions for a simpler version that assumes zero FP at bottom.
2272 Fixes bug of truncated stack reports.
2274 * target.h (target_lookup_symbol): Define this routine's args
2275 and result, finally.
2277 * target.c (nosymbol): Default routine for target_lookup_symbol.
2278 (target_default): Default lookup_symbol and call_function too.
2279 (files_info): Only print has_all_memory warning if a non-dummy
2282 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
2283 vx_convert_from_virtual): If target does not have floating point,
2284 zero register "values", and avoid doing cross-net conversions.
2285 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
2286 (vx_open): Rearrange code that attaches to target and reads
2287 symbols for all loaded modules, to work if some of the modules
2288 are not accessible. Add symbol_stub() and add_symbol_stub()
2289 as callbacks from catch_errors(). Allow connect attempt to be
2290 interrupted painlessly with ^C (FIXME, there are still some bugs
2291 if the interrupt happens during symbol reading.). Print
2292 final message with puts_filtered, since symbol messages are
2297 * main.c (catch_errors): Only print errstring if non-null.
2298 (command_loop): Avoid an ioctl per command to test ISATTY.
2300 * remote-vx.c (net_load): make static; avoid sophomoric msg.
2301 (vx_xfer_memory): Return correct result!
2302 (vx_files_info): Indicate whether target has float or not.
2303 (vx_lookup_symbol): Complain, not error, if target gone.
2304 (vx_open): Print "Connected" msg before disabling immediate-quit.
2305 [FIXME: lookup_symbol and vx_open changes need testing.]
2307 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
2308 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
2309 contributor lines and update copyrights to 1991.
2311 Changes from an attempted H-PUX host port:
2313 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
2314 defines PT_ATTACH and PT_DETACH but not PT_KILL.
2315 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
2316 * remote-vx.c: include <sys/time.h> for HPUX.
2317 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
2318 "core_file_command" routine to BFD regime. May not work yet.
2320 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
2322 * xgdb.c: Replace X10 version with some VJ version.
2323 (FIXME: Its copyright assignment is not on record.)
2324 * xgdb.c: Update include files to X11R4 (Xaw crud).
2325 (xgdb_display_source, create_text_widget): fix call to
2326 get_filename_and_charpos. Rewack source window stuff for X11R4
2327 (gleaned from include files, and "nm's" of binary libraries, since
2328 I had no doc available).
2329 (append_selection, append_selection_word): Disable with FIXME
2330 since R4 changed interface here.
2331 (create_buttons): Add back the old set of buttons.
2332 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
2334 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
2335 Roll VERSION to 3.94 (not yet final though).
2337 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2339 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
2340 obstack_int_grow, obstack_int_grow_fast): Eliminate
2341 cast on left of assignment, which gives MIPS cc fits and is
2344 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
2345 F_ALIAS. Use printf, not fprintf, when not passing a file
2347 (compare_opcodes): Check that identical instructions have
2348 identical opcodes, complain otherwise.
2350 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
2351 was reported by Roland McGrath.
2352 (unimp): Only match if exactly zero instruction. (Roland)
2353 (branches and traps): Generate all variations of these
2354 instructions with macros, based on a single call that defines
2355 each condition name and its binary representation.
2356 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
2358 * valprint.c (val_print_fields): Take, and use, format parameter.
2359 This means that "p/x struct" again prints the elements in the
2360 desired format. Changed callers.
2362 * stack.c (frame_info): Use filtered output, and indicate wrap
2363 points. Remove kludgy formatting designed to avoid line wrap.
2365 * utils.c (wrap_here): If the line is already full (because
2366 we had printed a long indent or long wrapped string), do an
2367 immediate newline-and-indent.
2369 * m68k-pinsn.c (print_insn_arg): Bugfix from
2370 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
2371 instruction is incorrectly disassembled as bkpt #8.
2373 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
2374 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
2375 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
2376 and then will dump core (sometimes). I traced it back to an
2377 uninitialized symfile_name in psymtab_to_symtab.
2378 (const_vol_complaint): Add quotes to message.
2379 (define_symbol): Only believe line number if gcc_compiled.
2380 Avoid allocating symbol if we will not return it.
2382 Add target strata support so that newly established targets go
2383 into their right place in the target stack (e.g. a new exec file
2384 doesn't wipe out the ability to access the running process).
2386 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2387 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2388 and initialize it properly in all the targets.
2390 * target.h: Document strata. Change return type of push_target.
2392 * target.c (nomemory): new function for dummy memory access.
2393 (tcomplain): Rename complain, now also used in symfile.c.
2394 (push_target): Push targets within strata. New return value shows
2395 whether new target is on top of stack or not. Always keep dummy
2397 (target_files_info): Ignore dummy target.
2399 * core.c (core_open): Warn user, and skip accessing file, if the
2400 core target is not the topmost target in the stack.
2401 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2404 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2405 target_ops, it doesn't belong there since we have no regs there.
2406 Change name of target from machine => memory to clarify.
2408 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2410 * Freeze version 3.93 for release.
2412 * Makefile.dist: Handle vx-share and nindy-share subdirs
2413 properly when building gdb.tar.Z.
2415 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2416 printed in various places, so I could change just one copy.
2418 * dbxread.c, coffread.c: Change references to bfd->iostream
2419 to cast to FILE *, now that BFD avoids needing types defined
2420 in other header files.
2422 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2424 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2425 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2426 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2427 (actually gcc -Wall).
2429 * dbxread.c: Remove first_global_sym, last_global_sym, since
2430 they are never referenced.
2432 * defs.h (baud_rate): Declare.
2433 main.c: Define it, and add the -b option to set it.
2435 * gdb-int.texinfo: Add text on how to define a new host or target
2436 architecture, prompted by Per Bothner's questions about MIPS
2439 * gdb.texinfo: Document "complaints". Change doc of -q since
2440 gdb no longer prints the copyright and blurb if you specify a file
2441 name to be debugged (just like Emacs). Add doc for Nindy-specific
2442 command line flags for specifying target serial port and such.
2443 Update copyright to 1991.
2445 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2446 has taken over for us the job of ripping up executable files. The
2447 crud caused Per Bothner's port to not compile.
2449 * infrun.c (normal_stop): Avoid printing "Program exited
2450 normally" if we are in batch mode. This allows a GDB which
2451 executes a program on a target system, to behave like a Unix
2452 command (input from stdin, output to stdout, no extraneous
2455 * main.c (main): Allow additional machine-dependent command line
2456 options to be specified with the ADDITIONAL_OPTIONS,
2457 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2458 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2459 processing to occur just before the main loop with
2460 BEFORE_MAIN_LOOP_HOOK.
2461 (main): If a "core file" argument is specified, and it is not a
2462 core file, try it as a process ID to attach.
2463 (symbol_completion_function): Attempt to cope with
2464 "show screen-" TAB, not very successfully. This needs more work,
2466 (batch_file): New function, returns whether we are reading
2467 commands from an interactive tty on stdin, or from somewhere else.
2468 Called by normal_stop since it doesn't get from_tty passed down
2469 to it like many commands do.
2471 * remote-nindy.c: Handle command line options for nindy
2473 (nindy_before_main_loop): Prompt user for tty name if they
2474 don't specify it before getting to the interactive command loop.
2476 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2477 and -r command line options. Also add hook before main loop
2478 to make it easy to specify a tty.
2480 * TODO: More things to do, one done.
2482 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2484 * dbxread.c: Make complaint() calls pass pointer, not struct.
2485 Add complaints about badly formatted C++ type information
2486 (const/volatile indicator, and parse errors resulting in
2487 error_type). Fix C++ virtual member fn comment.
2488 (read_struct_type): Avoid bumping pointer if we got a parse
2489 error; this prevents our walking beyond the end of a string.
2490 Terminate loop on null char as well as semicolon.
2491 (process_one_symbol): Fix the LBRAC fix so that it uses the
2492 last previous SLINE, FUN, or SO record's PC address. C++ debug
2493 symbols did not have SLINE records in a useful order compared
2494 to the LBRAC records.
2495 (define_symbol): Handle "catch" records.
2497 * symtab.c (check_stub_type): Added new complain
2498 `stub_noname_complain' and added a consistency check to
2499 keep the debugger from crashing when finishing from an
2500 exception frame. A real fix will be needed later.
2502 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2504 * infcmd.c (attach_command): Make global.
2506 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2507 but make them easy to comment out. Perhaps later they should
2508 be enabled by what CPU you configure for? FIXME.
2509 (VERSION): Roll to 3.93.
2510 (pinsn.o): Remove rule for obsolete file.
2511 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2513 Run down a problem that manifested by printing the wrong function
2514 name in stack traces of read_ofile_symtab. Turned out that the
2515 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2516 the LBRAC symbol with an address in the *data* segment, which
2517 blew our binary search through the blocks.
2519 * dbxread.c: Use the complain() facility consistently to bitch
2520 about problems in the symbol file we are reading.
2521 (finish_block): Add code to check the nesting of the blocks;
2522 complain and Procrust them to fit if wrong.
2523 (make_blockvector): Check the order of the blocks, complain
2524 [but don't cope] if wrong.
2525 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2526 symbols to be sure their PC value is greater than the last SLINE
2527 (line number) symbol we've seen, complaining and adopting the
2528 SLINE PC value if wrong.
2530 * symfile.h (struct complaint, complaint_root, complain,
2531 clear_complaints): Add.
2532 * symfile.c (complain, complaint_root, clear_complaints): Add
2533 facility to deal with non-fatal complaints and to regularize their
2535 (symbol_file_add): Clear complaint counters to allow new complaints.
2536 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2538 * dbxread.c (dbx_symfile_read): Remember the address and size
2539 of the string table for the main symbol file, so we won't read it
2541 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2542 to avoid reading the string table yet again. Lint.
2543 (throughout): Improve filtered output, including word wrap.
2544 (read_range_type): Improve Bothner's fix to handle other types too.
2546 * utils.c: Improve line wrap implementation. Handle unlimited
2547 width by making chars_per_line unsigned.
2548 (puts_filtered): New, easy, function.
2550 * defs.h (puts_filtered): add.
2552 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2553 call the identical sort_symtab_syms() in symfile.c instead.
2555 * expread.y: Suggest the `file' command rather than `symbol-file'.
2557 * command.h (enum var_types): Add zinteger for seroable
2559 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2560 nested if's into a switch.
2562 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2563 we did not stop because of a breakpoint (it must have been for
2564 some other reason, like a "stepi"), so don't print anything.
2566 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2567 doesn't include <sys/types.h>, old SunOS's require it for
2570 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2572 A test port of gdb-3.92.6 to the Sony NEWS.
2575 Don't normally link in remote- or vx stuff.
2576 Some of it doesn't compile, and it wastes space for 99% of the users.
2577 Remove reference to no-longer-used HAVE_VPRINTF.
2578 Fixed BFD_DEP typo to BFD_DIR.
2580 Fix cast in arg to bfd_h_getlong.
2581 Make char *prefix be const.
2582 Fix how certain range types are mapped into builtin unsigned int types.
2584 Remove 2 #includes. They cause errors (on Sony, at least),
2585 and aren't needed (they wern't in earlier versions).
2587 print_address_symbolic should never demangle labels
2588 (since it prints *assembler-level* labels).
2590 [This was superseded by the change to printcmd below.]
2593 Add some "volatile" return types to avoid warnings.
2594 If MISSING_VPRINTF add vprintf function and not just macro
2595 (since vprintf is used in printcmd.c).
2597 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2598 (The latter isn't grokked by some PCC-based compilers.)
2600 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2602 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2603 * nindy-share/coffstrip.c
2604 Added some forward declarations (otherwise, gcc complains
2605 about implicit extern redefined as static).
2607 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2609 Changes inspired by Per Bothner:
2610 * printcmd.c (print_address_symbolic): Take additional parameter
2611 specifying whether to demangle.
2612 (print_address): Pass in asm_demangle to control demangling.
2613 (print_address_demangle): New fn, takes explicit arg to control
2615 * utils.c: Add new vars demangle and asm_demangle, and let them
2617 (fputs_demangled): If !demangle, just print the argument.
2618 (fprint_symbol): If !demangle, just print raw symbol.
2619 * valprint.c (val_print): Call print_address_demangle rather than
2620 print_address, to cause demangling to depend on the global
2621 rather than assembler-level demangling setting.
2622 * WHATS.NEW, gdb.texinfo: Document.
2624 * main.c (show_command): Show all settings if no arg.
2625 (initialize_main): Make "info set" the same as naked "show".
2626 * command.c (cmd_show_list): Handle prefix commands in the
2627 list, and print the name of the setting as well as its English
2628 description and value.
2630 Allow gdb functions to specify where a line should wrap if it
2631 exceeds the size of a terminal line. Use it to make the output
2633 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2634 of the right size when screen width changes.
2635 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2636 (wrap_here): New fn, indicates a point in the output where we
2637 should wrap the line rather than just letting it overflow at a
2639 (fputs_filtered): Implement wrapping.
2640 (n_spaces): New fn, returns a pointer to N spaces.
2641 (print_spaces_filtered): Use n_spaces.
2642 * defs.h (n_spaces): Declare.
2643 * stack.c (print_frame_info): Wrap with 4-space indent after
2644 fn name and before filename and line number.
2645 * printcmd.c (print_frame_args): Wrap with 4-space indent
2646 before each argument name is printed.
2647 * valprint.c (value_print): Wrap with no indentation before
2649 (val_print_fields): Wrap with indentation relative to nesting
2650 level before each field name.
2651 (val_print): Wrap with nesting indentation before array elements.
2652 * command.c (do_setshow_command): Avoid extra newlines,
2653 wrap with 4-space indent around values printed, end with period.
2654 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2656 * breakpoint.c (breakpoint_1): Implement addressprint for
2657 "info breakpoints" display. Change file name and line number
2658 format to " at file:nnn" rather than " (file line nnn)".
2659 * gdb.texinfo: Document.
2662 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2664 Frozen for gdb-3.92.6 release.
2666 README, WHATS.NEW: Update for 3.92.6 release.
2668 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2669 coffread.o from configs since it is now built by default.
2670 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2671 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2672 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2673 from configs since it is now built by default.
2675 Makefile.dist: Update for release 3.92.6. Handle files that
2676 have been moved to ../include, ../getopt, or ../bfd. Add
2677 saber.suppress and tests directory. Add config.status to
2678 the release (it will say "none").
2680 coredep.c: Minor formatting fixes.
2682 These changes were made in early December but only checked in now:
2683 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2684 nindy-share/nindy.c: lint
2685 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2686 register values coming back from the target; we store values
2687 in target byte order everywhere.
2689 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2691 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2693 * valprint.c (cplus_val_print, val_print_fields): New functions,
2694 which print C++ objects. They conspire to avoid printing a
2695 virtual base class more than once, following all the twists and
2696 turns of C++ virtual base rules.
2697 (val_print): Call the above rather than do it by hand.
2699 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2700 symbol file, not for added files like shared libs. This really
2701 needs to be generalized to a timestamp per file.
2703 * core.c (cleanup_core): Avoid coredump if no core file.
2705 * config.gdb: Accept -host or -target in place of +host or
2708 * coffread.c (find_linenos): Avoid desupported BFD interface
2709 to line numbers. We still read them manually rather than using
2710 BFD's "generic" features.
2712 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2714 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2716 * Makefile.dist: Eliminate use of $< in explicit targets.
2718 * readline/Makefile: Use $< rather than $*.c, which does not
2719 include the VPATH in GNU Make.
2721 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2722 copies of tconfig/i960, added for global configuration
2723 compatability. All i960 versions can read both coff and b.out.
2725 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2726 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2729 * TODO: Think of more things to do.
2731 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2733 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2734 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2735 64-bit float conversion.
2737 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2738 equivalent to sun?os4 so global config works.
2740 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2742 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2744 * main.c: Only declare linesize once; declare pagesize not at
2745 all, since it is never used.
2746 (main): Clear newly allocated line before it is used.
2748 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2750 Further stabilization for the Intel 960.
2752 * Makefile.dist: Parameterize the location of the "include"
2753 and "bfd" directories, as well as "getopt". Add symfile.c.
2754 Link in both dbxread and coffread. Fix up "make depend" to
2755 rewack the locations of include, bfd, and getopt in its output.
2757 * README: Document moving include files, improve some of
2760 * coffread.c: Move common code out to symfile.c. Change
2761 symbol_file_command style interface to use new *_symfile_init
2762 and *_symfile_read interface under BFD. Use BFD internal
2763 info to locate line table, symbols, etc.
2765 * core.c (core_fetch_registers): Rename to get_core_registers
2766 to avoid confusion with fetch_core_registers.
2767 (register_addr): Move to coredep.c, which is already machine
2768 dependent. This leaves core.c pretty clean of dependencies.
2770 * coredep.c (register_addr): Accept this routine from core.c.
2772 * dbxread.c: Move common code (with coffread.c, etc) into new
2773 symfile.c. Each psymtab now contains a pointer to the
2774 format-dependent function that knows how to read it in. Make
2776 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2777 (process_one_symbol): Add code to complain about a "compiler bug
2778 we muzzle here", if we actually see it.
2780 * eval.c (evaluate_subexp): Insert missing "break" statements
2781 in code that determines whether a variable is an lvalue in
2782 memory, register, or whatever. I detected this via a compiler
2783 bug in which it *almost* mashed out the whole switch statement.
2785 * gdb-int.texinfo: Add minor sections on configuring gdb for
2786 release, and about the README file.
2788 * infcmd.c (registers_info): Fix formatting somewhat. Still
2789 not as pretty as before, but it handles byte swapping.
2791 * remote-nindy.c: If data cache routines are interrupted while
2792 waiting for the remote end, be sure that any uninitialized cache
2793 blocks are on the free list, not on the valid list!
2795 * symfile.h: Flesh out this header file with all the various
2796 routines and variables that have been merged in from dbxread.c
2797 coffread.c, and symtab.c to symfile.c.
2799 * symfile.c: New file, containing code common to dbxread.c,
2800 coffread.c, and some code from symtab.c. All generic code for
2801 reading symbol files should be in here now.
2802 (unrecord_misc_function): Remove unused function.
2804 * symtab.h: Remove file-reading things to symfile.h.
2806 * symtab.c: Remove file-reading things to symfile.c.
2808 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2809 to decode i960 fault types.
2811 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2812 target.c: Change type of the "resume" function from int to void,
2813 since its result was never used.
2815 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2817 * main.c: Replace "stupid" with "caution"; you now "set caution
2820 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2822 * infcmd.c (do_registers_info): Call val_print to deal with the
2823 byte order of the registers being printed. FIXME, this makes
2824 the formatting of the output uglier.
2826 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2827 defined, call it for signals the debugger doesn't itself use.
2828 The i960 uses this for more detailed fault information.
2830 * remote.c (remote_open): If arg is null, print help rather than
2833 * sparc-xdep.c (register_valid): Avoid declaring size, since
2834 various modules will think of various sizes depending on the
2835 architecture of their tm-file. FIXME, we need protection against
2836 actually entering one of those modules, which would clobber
2837 storage if not for the target architecture compiled into gdb.
2839 * stack.c (up_command, down_command): Always print the frame
2841 (up_silently_command, down_silently_command): New commands
2844 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2846 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2847 more parameters than it used to.
2849 * findvar.c (registers): Increase slop to 256 bytes, which should
2850 protect us against even most RISC machines with large register
2852 (locate_var_value): Move declaration inside related ifdef.
2854 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2855 throughout, to avoid throwing away buffered input from the board.
2856 (nindy_wait): Supply_register takes addr_of_value, not value.
2857 (i960_print_fault): Renamed from i80960_fault.
2858 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2859 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2861 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2862 we can set the PC in the call to proceed(). Unpush nindy_ops
2863 before pushing it on top, to avoid message to user. Eliminate
2864 commentary from Unix machines that just misleads here.
2865 (reset_command): Fix error message to suggest target command.
2867 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2869 Release 3.92.5 as frozen.
2871 Stabilize the merged release...with help from lint, Saber C,
2874 Everywhere: Add include files needed to declare return types
2875 of functions called.
2877 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2879 * breakpoint.h: Add undeclared breakpoint functions, and some
2880 functions for display handling since I couldn't think of a better
2883 * breakpoint.c (insert_breakpoints): Make code for disabling
2884 shared library bkpts more likely to work. It's used when we
2885 rerun a program and stop before the shared library has been
2887 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2888 cast from pointer, so it squeezes through catch_errors.
2889 (bpstat_stop_status): Fix logic broken some time ago. We now
2890 always create a bpstat if the stop address matches a breakpoint,
2891 even if we don't stop there -- just like the old code used to do
2892 before I got my fingers into it (sigh).
2893 (breakpoint_1): Print "ignore count" after "stop only if"
2894 condition, since that's how it actually works.
2895 (mention): Handle watchpoints as well as breakpoints.
2896 (watch_command): use set_raw_breakpoint and mention to do most
2897 of the work (and initialize all the fields!). Only pass one
2898 arg to parse_c_expression, since that's all it takes.
2900 * command.c (not_just_help_class_command): Rename arg to args
2901 since we ignore "unused argument" warnings on vars named "args".
2902 inflow.c (child_terminal_info): ditto.
2903 infptrace.c (kill_inferior): ditto
2904 main.c (catch_errors, version_info, quit_command, pwd_command,
2905 source_command, dump_me_command, editing_info,
2906 set_history_size_command, set_history, show_history,
2908 stack.c (locals_info): ditto
2909 target.c (target_files_info): ditto
2910 valprint.c (set_input_radix, set_output_radix): ditto
2912 * core.c: Remove old variables for handling core and exec file
2913 sections (data_start, data_end, stack_start, stack_end,
2914 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2915 text_end, exec_data_start, exec_data_end, text_offset,
2916 exec_data_offset, data_offset, stack_offset). They're
2917 superseded the more general build_section_table and
2919 (get_exec_file): Mention the `file' command.
2920 (read_memory_check): Rename to memory_error, and only call it
2921 in the case of an actual error.
2922 (read_memory, write_memory): call memory_error.
2923 (core_fetch_registers): Register section name is ".reg".
2925 coredep.c: Remove a bunch of crud now that all this file does
2926 is pull the registers out of a core file.
2927 (fetch_core_registers): Rewrite to actually work, I hope.
2929 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2930 Replace index() with strchr(). Remove all the pre-BFD macro
2931 definitions for accessing the symbol file.
2932 (struct dbx_symfile_info): Encapsulate the information that
2933 dbx_symfile_init needs to pass to dbx_symfile_read in this
2936 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2937 dbx_symfile_discard): Rearrange symbol file reading to divide
2938 the format-specific part from the format-independent part,
2939 leaving the format-independent part such as file name expansion
2940 and opening in symtab.c. This replaces
2941 partial_symbol_file_open and partial_symbol_file_read.
2942 Symbol_file_read, add_file, add_file_target_command,
2943 add_file_addr_command move to symtab.c. Pass an explicit
2944 "mainline" flag for when reading the main symbol table, rather
2945 than relying on the offset address to be zero or nonzero.
2947 (dbx_symfile_read): Don't allow void *'s to be printed as
2949 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2950 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2951 macro" debug version really work.
2952 (read_dbx_symtab): Remove unref'd parameter inclink.
2953 Avoid swapping N_SLINE symbols, for speed.
2954 Merge N_TEXT!N_EXT case with the other external symbol
2955 definitions' case. Add comments.
2956 (start_psymtab): Allocate the symfile name in the psymtab on
2957 the psymbol_obstack, rather than using the caller's storage.
2958 (end_psymtab): Only allocate a dependencies list if there are
2960 (psymtab_to_symtab_2): Use BFD when reopening file to read
2961 its symbols for real.
2962 (read_struct_type): Add FIXME comments where it needs work
2964 (read_huge_number): Add FIXME about overflows.
2965 (read_range_type): Add FIXME about comparing a long to 1<<32.
2967 * coffread.c: Minor changes to move things closer to the new
2968 regime with symtab.c and dbxread.c Major work is still needed
2971 * exec.c (exec_file_command): Remove old variables (see core.c
2973 (xfer_memory): If memory transfer is right at the end of a
2974 section, don't lose.
2976 * findvar.c (get_saved_register): If value is in a real
2977 register, LVAL is lval_register, not lval_memory.
2979 frame.h: Declare print_sel_frame and record_selected_frame.
2981 gdb-int.texinfo: New file, for GDB internals documentation.
2982 Very simple, unformatted doc of cleanups is there for now.
2984 gdbcore.h: Remove obsolete variables that described a.out
2985 section addresses and offsets. (See core.c above.)
2986 Declare fetch_core_registers and registers_fetched.
2988 getopt.c: Declare char *alloca(); even on SPARC.
2990 infcmd.c (run_command): Call target_kill rather than
2992 (step_command, next_command, stepi_command, nexti_command):
2993 Declare from_tty parameter even though we don't use it.
2994 (run_stack_dummy): argument BUFFER is a char array, not
2995 a pointer to REGISTER_TYPE.
2996 (finish_command): using_struct_return needed a value *,
2997 not a struct symbol *.
2999 * infptrace.c (child_xfer_memory): To avoid dependency on
3000 where sections are in memory, try PT_WRITE_D and if that fails,
3001 try PT_WRITE_I. Most Unixes don't care which you use.
3003 * infrun.c (step_resume_break_shadow): Change to array to
3004 match other breakpoint shadow storage.
3005 (clear_proceed_status): Pass address of bpstat to
3006 bpstat_clear, not the bpstat itself.
3007 (child_create_inferior): FIXME comment about if the child
3009 (start_inferior): Remove old function.
3010 (child_open): Use target_kill rather than kill_inferior.
3011 (wait_for_inferior): Ditto.
3012 (insert_step_breakpoint, remote_step_breakpoint): Use
3013 new step_resume_break_shadow.
3015 * inftarg.c (child_wait): If all child processes die,
3016 pretend that the one being waited for exited with signal 42.
3018 * main.c (command_line_input): When scanning for comments,
3019 don't coredump on unclosed quotes.
3020 (quit_command): Use target_kill rther than kill_inferior.
3021 (_initialize_main): Rename class_user from "user" to
3024 * printcmd.c (print_command_1): Initialize "fmt" if no format
3025 is specified by the user.
3026 (print_frame_args): Only add to args_printed if we are
3027 actually fetching args from the stack (avoiding undefined
3029 (_initialize_printcmd): Remove bogus \{ from string.
3031 * remote-eb.c (eb_open): Avoid coredump on no argument.
3033 * remote-nindy.c: Bring out of Intel environment into new
3034 target environment. Remove all conditional compilation on
3035 I80960. Massive hacking throughout.
3036 (nindy_xfer_inferior_memory): New routine stolen from
3038 (nindy_create_inferior): New routine pieced together, probably
3039 not quite working yet.
3040 (nindy_ops): New target_ops struct for nindy.
3042 * remote-vx.c: Use write_memory rather than target_write_memory
3043 to get error checking.
3044 (vx_add_file_command, vx_open): Use symbol_file_add rather than
3046 (vx_create_inferior): Use target_terminal_ours...
3048 * signame.c (_initialize_signame): Always initialize, since
3049 we need the table for things other than psignal.
3051 * solib.c (solib_add): Use symbol_file_add, not add_file.
3052 (solib_address): Return boolean result rather than struct
3053 pointer which nobody else knows the type of.
3055 * sparc-tdep.c, valops.c: Use write_memory rather than
3056 target_write_memory, to get error checking.
3058 * stack.c (locals_info, catch_info, args_info,
3059 get_selected_block, frame_command, up_command): Use
3060 target_has_stack, rather than have_inferior_p or
3063 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
3065 * symfile.h: New file, defining the interface between the
3066 generic and object-file-specific symbol reading code.
3068 * symtab.c: Move generic symbol-reading interface to symtab.c,
3069 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
3070 table to map BFD targets to symbol-reading modules in GDB.
3071 Change index to strchr.
3072 (lookup_struct_elt_type): Use error() rather than hand-made
3073 simulations thereof.
3074 (lookup_partial_symbol): Speedup slightly when length == 0.
3075 (symbol_file_add): New function.
3076 (symbol_file_command): Call it.
3077 (symfile_open, symfile_init): New function.
3078 (add_file_target_command, add_file_addr_command): moved from
3081 * target.c (target_command): use target_kill.
3083 * target.h (target_files_info): Don't declare, never called
3086 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
3087 files to determine stack end address.
3089 * valarith.c (value_x_binop, value_x_unop): Change error message
3090 to be more useful. Pass proper argument to value_struct_elt.
3092 * valops.c (value_assign): FIXME comment that long long
3093 bitfields will break here.
3095 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
3096 Update `make saber_gdb' to work better.
3098 * TODO: A woman's work is never done.
3100 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
3101 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
3102 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
3103 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
3104 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
3105 valops.c, valprint.c, exec.c: Lint.
3108 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
3110 Continuing Intel 960 port merge of GDB.
3112 * Makefile.dist: Merge i960 "nindy-share" files. Rename
3113 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
3114 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
3115 Wack over "make depend" so it handles files in subdirectories
3116 vx-share, nindy-share, bfd, and in the current directory.
3118 * blockframe.c (get_prev_frame_info): Remove fatal error
3119 if stack not defined.
3121 * core.c (core_open, core_detach): New functions that handle
3122 the old "core-file" command as "target core" and "detach" instead.
3123 (core_file_command): Call them.
3124 (core_xfer_memory): Use common routine xfer_memory.
3126 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
3127 dbxread now uses bfd for everything but symbol reading itself.
3128 BFD internals are used to drag out the relevant file offsets.
3129 (partial_symbol_file_open): Change args all around for BFD.
3131 * symtab.c: Rename "value" to "val" everywhere, so we can
3133 (symbol_file_command): New command, moved from dbxread.c
3134 and coffread.c. It uses BFD to read the file, then vectors
3135 based on its type, to dbx or coff symbol readers.
3136 * symtab.h: Extern a few vars for symbol_file_command.
3138 * target.h: Breakpoint takes a char * save area, not a char **.
3140 * valprint.c (val_print): When unpacking bitfields, offset
3141 the address in gdb of the value, if it is declared with a shorter
3142 type. Remove the last "runtime kludge test" of host byte order.
3144 * utils.c: Remove old my_bfd_read routine.
3146 * stack.c (frame_info): Use target_has_stack. Print program counter
3147 register's actual name rather than "pc", since it's called the
3148 "ip" (instruction pointer) on the i960 (sigh).
3150 * target.c (target_command): Add command for selecting a target
3151 type and calling its open routine. This is used for initiating
3152 communication with a particular target, in a generic way.
3154 * tm-i960.h: Update for modern gdb. Remove semicolons from
3155 various macros. Handle reading struct return convention, and
3156 error-out attempts to return structs with the "return" command.
3157 Be sure gdb doesn't think we know how to call functions in the
3160 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
3161 to i960_xxx in lower case.
3162 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
3163 not being defined yet.
3165 * remote.c (remote_open): Call start_remote to initialize
3166 wait_for_inferior during open.
3167 (remote_xfer_inferior_memory): Return length written rather
3170 * remote-vx.c (target_command -> vx_open): Use new generic
3172 * remote-eb.c, inftarg.c, exec.c: ditto.
3174 * infrun.c: Fix comments.
3175 (attach_program -> child_open): Use new generic target command.
3176 (wait_for_inferior): Clear saved register values before target_wait,
3177 so target_wait can set some of them if convenient.
3179 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
3180 Return success indicator, not void.
3181 (child_xfer_memory): Avoid fetching initial word if we'll
3182 overwrite it anyway.
3184 * infcmd.c (attach_command): Use new generic target open routine.
3185 (_initialize_infcmd): Update doc on attach and detach commands.
3186 (do_registers_info): Merge in a byte-order problem as a FIXME
3189 * findvar.c (find_saved_register): Avoid problem in current frame.
3190 (read_relative_register): Ditto.
3191 (write_register): Convert byte order on the way out.
3193 * exec.c (file_command): Add.
3194 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
3195 (xfer_memory): Common function between core_xfer_memory and
3197 (exec_xfer_memory): Use it.
3199 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
3201 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
3202 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
3203 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
3205 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
3207 Merge Intel 960 port of gdb, continuing...
3209 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
3210 symbol_file_command): Pass from_tty arg to hush 'em up.
3212 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
3213 Add magic numbers for 960 COFF format.
3215 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
3217 Merge Intel 960 port of gdb, from Intel "1.2" release.
3219 CHANGE_LOG entries from their port, which was based on
3222 Thu Sep 6 11:02:22 PDT 1990
3223 Remove temp file if download is interrupted.
3225 Wed Aug 1 09:08:33 PDT 1990
3226 Now uses binary protocol to talk to NINDY.
3227 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
3228 Times out after 5 seconds when trying to talk to NINDY.
3230 Tue May 29 12:54:49 PDT 1990
3231 Added variable baud rate (-b switch).
3232 Source code reorganization.
3234 Thu Apr 26 11:09:55 PDT 1990
3235 More cleanup of batch mode; specifically, execute "-s", "-e", and
3236 "-se" switches as soon as they are encountered on the invocation line.
3238 Fri Apr 20 13:47:15 PDT 1990
3241 Thu Apr 19 09:54:28 PDT 1990
3242 Add 'reset' command.
3244 Wed Apr 18 09:48:07 PDT 1990
3245 After opening remote tty, wait for 1 second to go by without input
3246 from it before trying to talk to NINDY (fixes problems with the
3247 Heurikon HK80/V960E).
3249 Mon Apr 4 16:33:05 PDT 1990
3250 Some output was not being suppressed in 'batch' mode.
3252 Thu Mar 22 15:31:11 PST 1990
3253 Ask user if old symbol table should be deleted when new file is
3256 Allow user to run a program downloaded before gdb960 was brought up.
3258 Correct "exec-file" help message for i80960 context.
3260 Correct bug in calculating user space address: could occasionally
3261 corrupt user program.
3263 Make sure to zero low-order bits in rip's because of bug in 960CA
3264 A-step part: could cause operation faults when "next"ing across
3267 Correct bug that made it impossible to get source line numbers for
3268 code loaded at addresses higher than 0x7fffffff.
3270 Wed Jan 10 12:43:22 PST 1990
3271 Open remote tty for exclusive use.
3273 Fri Jan 5 12:14:42 PST 1990
3274 Correct disassembly (CA manual was right after all):
3275 opcode for sysctl is 0x659
3277 Mon Oct 23 12:03:04 PDT 1989
3278 Use G960BASE and G960BIN environment variables to find 'sx' utility.
3280 Mon Oct 16 14:15:09 PDT 1989
3281 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
3283 Mon Oct 2 15:56:31 PDT 1989
3285 Added 960CA disassembly support.
3287 To simplify maintenance:
3288 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
3290 - eliminated opcode.h: incorporates tables into i960-pinsn.c
3291 - moved 960-specific routines from i960-pinsn.c to i960-md.c
3292 - made disassembly interface identical to that in gdmp960.
3296 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
3298 * target.h: Allow targets to stack. Add target_has_memory,
3299 _registers, etc. Restructure memory access and "info files"
3300 to walk the target stack.
3301 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
3302 target.c: Change tables to match target.h.
3303 * inflow.c (child_mourn_inferior): pop child_ops.

3307 * remote-eb.c: New memory regime, new info files.
3308 * remote-vx.c: New memory regime, new info files. Now use
3309 separate targets for VxWorks attachment to machine, and
3310 actually running a process under VxWorks, since one has
3311 stack & execution & regs and the other doesn't.
3312 * remote.c: New memory regime, new info files.
3313 * sparc-xdep.c (fetch_core-registers): New memory regime.
3314 * target.c: New routines and support for stacked targets,
3315 new memory regime, new info files regime.

3319 including use of the new BFD (binary file) library.
3320 * gdbcore.h: Add struct section_table.
3321 * exec.c (build_section_table): Iterate all sections and
3322 record what gdb needs to know about them.

3329 * dbxread.c: Quick changes to make it compile with new BFD.
3330 * utils.c (error): Avoid using bfd_error in generic routines.
3332 * core.c (core_fetch_registers): Get from the ".regs" section of
3334 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
3336 * inferior.h (attach_flag): Export.
3337 * infcmd.c (run_command): use new target_create_inferior.
3338 * infrun.c (child_create_inferior): Don't return result.
3339 * Makefile.dist (VERSION): 3.91.4.
3341 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
3343 * breakpoint.c (bpstat_num): Handle breakpoints which have
3344 since been deleted, such as temporary breakpoints.
3345 infcmd.c (program_info): ditto.
3347 * core.c (core_file_command): Display the frame where the core
3352 * remote-vx.c (target_command): Merge in target command from
3353 targ-vx.c. A few other cleanups.
3355 * TODO, Projects: Lots more stuff to do...
3357 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
3359 Massive changes to wall off the remote-debugging interface
3360 behind a function vector. The port to handle VxWorks targets
3361 is also part of this.
3363 All files: Replace references to renamed functions,
3364 remove references to remote_debugging, remove references to
3365 have_include_file, have_core_file in favor of target_has_stack,
3366 target_has_memory, etc.
3368 * Modularize the breakpoint interface.
3369 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
3370 a breakpoint instruction.
3371 breakpoint.c: struct breakpoint's shadow_contents now sized as
3373 (insert_breakpoints): Vector to target to install breakpoints.
3374 (remove_breakpoints): Vector to target here too.
3375 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
3376 sparc-tdep.c (single_step): Use new breakpoint interface for
3377 the single-step breakpoints.
3378 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
3379 New file, contains routines to insert and remove breakpoints by
3380 reading out the old contents and later replacing them. This is
3381 how ptrace breakpoints work, and many remote systems as well.
3383 * tm-vxworks68.h: New config file, overrides a few things for
3384 Wind River's preferences.
3386 * target.h: New file, for transfer vector used to talk to the
3387 inferior (child, attached, core, exec, remote, etc). All accesses
3388 to the thing being debugged should come through these vectors.
3389 target.c: New file, routines to handle transfer vector.
3390 (various files): Add transfer vectors XXX_ops for the various
3391 targets and pseudo-targets (core files, etc) we support.
3393 * breakpoint.c (bpstat_stop_status): Further explorations of
3394 watchpoints and why things don't work all the time.
3395 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3397 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3398 the local gdbinit if it doesn't already have it.
3400 * core.c (core_ops): add and install.
3401 Allow core debugging without exec file.
3403 * dbxread.c (free_and_init_header_files): Merge two fns.
3404 (end_symtab): Free named symbol table when a new version comes in.
3405 (read_dbx_symtab): Relocate all kinds of symbols with base
3406 address. First step toward handling different text, data, bss
3408 (add_file_addr_command): Renamed add_file_command.
3409 (add_file_command): Vector to remote handler.
3410 Add "load" as an alias for "add-file" command.
3412 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3413 non-returning functions.
3415 * exec.c: Add exec_ops, and push it as a target when an exec
3418 * infcmd.c (run_command): Pass executable file name and arg list
3419 separately when starting an inferior. Permit "run" when no exec
3420 file is specified, for VxWorks.
3421 (detach_command): Move to child_detach in inftarg.c.
3423 * inftarg.c: New file. Unix-child-specific routines, and the
3424 child_ops structure.
3426 * inferior.h (registers): Export "registers" as the way for
3427 target dependent register handlers to find gdb's local copy of
3428 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3429 since it is now used by places that want wait_for_inferior to
3430 handle the grunge but want to see every trap from the inferior.
3432 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3433 Eliminate remote_debugging hooks in terminal handling.
3435 * infrun.c: Replace start_inferior with child_create_inferior.
3436 Move all the hair of Unix shells and ptrace idiosyncracies into
3437 child_create_inferior, so remote handlers don't have to deal.
3438 Remove running_in_shell. Rename stop_after_attach to
3439 stop_soon_quietly, and use it in a few other places where we want
3440 to just call wait_for_inferior and get control back on the first
3441 trap. trap_expected now never takes a value > 1.
3442 (init_wait_for_inferior): Initialize static vars when a new
3445 main.c (gdbinit): Add new hook for .gdbinit file name, let
3446 it be overridden by config files as GDBINIT_FILENAME.
3447 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3448 Both of these are used for VxWorks gdb.
3450 mcheck.c: rename include file "gmalloc.c" to avoid problems
3451 with system include file "malloc.c".
3453 param-no-tm.h: New include file, same as param.h but does not
3454 include the default "tm.h" file. This is used in files where
3455 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3457 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3459 remote-vx.c: New file, VxWorks remote debugging support. Uses
3460 RPC routines that are shared with the target system, in directory
3463 remote.c: Vectorize remote interface.
3465 source.c: Globalize source_path, and make an alias "l" for "list"
3466 since we now have the "load" command.
3468 sparc-xdep.c: Use new param-no-tm.h.
3470 symmisc.c (free_named_symtab): Add new function from Wind River.
3471 However, ifdef it out for now while we think about what it should
3474 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3476 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3477 non-Unix-children handle this with their own code in the target
3480 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3481 source and target lists. Add vx-share to default list of include
3482 directories. Add new files to src and target lists: mem-break,
3483 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3484 ${srcdir} versions of munch and createtags are used.
3486 * valops.c (find_function_addr): Split out of call_function.
3487 (call_function_by_hand): Rename call_function; this function
3488 calls functions in the target by laboriously patching the target
3489 word-by-word with the right stack, args, regs, etc.
3492 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3494 Handle AMD 29000 a bit better.
3496 * remote-eb.c (readchar): Mask received char log to make it readable.
3497 (remote_start): Pass arguments down to executing program.
3498 Make startaddr unsigned.
3499 infrun.c (start_inferior): Accept args, pass them to
3501 infcmd.c (run_command): Pass args down to start_inferior.
3503 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3504 the target object file format.
3505 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3507 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3508 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3510 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3512 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3513 * TODO: We did a few things, we have more to do though.
3515 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3516 * inflow.c (inferior_died): Clear deferred stores.
3518 * Debug problems with dummy frames and calls to the inferior.
3519 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
3520 * sparc-tdep.c (do_restore_insn): Simplify.
3521 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3522 (sparc_push_dummy_frame): Simplify and fix what we push.
3523 (sparc_pop_frame): Slightly more hair here, deciding whether
3524 we are restoring a saved PC or returning to a return address in %i7.
3525 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3527 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3528 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3529 * obstack.h (chunkfun): ditto.
3530 * defs.h (xmalloc, xrealloc): ditto
3532 * utils.c (quit): Grab the terminal from the child if necessary.
3534 * inflow.c (term_status_command): Rename to term_info, change
3537 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3538 (is_delayed_branch): Speed up.
3539 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3540 Still missing some float ops, and needs testing.
3542 * Support for input and output radixes other than base 10
3543 * defs.h (input_radix, output_radix): Declare.
3544 * expread.y (yyparse, parse_number): Handle changes of input
3545 radix, and ambiguous names-or-numbers in radixes >10.
3546 * printcmd.c (print_scalar_formatted): Print formatted hex
3547 numbers in varying column widths.
3548 * valprint.c (val_print): Use output_format to print scalar ints.
3549 (set_input_radix, set_output_radix, set_radix): Create.
3550 (set_output_radix): Set output_format from output_radix.
3551 (_initialize_valprint): add `set radix' but leave the others off.
3553 * main.c (execute_command): Let stupid questions be turned off.
3554 (_initialize_main): Handle "set stupidity", etc.
3556 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3557 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3559 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3561 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3562 bfd stuff is still screwed up, but with some manual work, it
3565 * breakpoint.c (bpstat_do_actions): Start over if a command
3566 proceeds the inferior, since the inferior will have stopped and
3567 will need to have its new stop-actions taken care of.
3569 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3570 compiler fits, simplify it.
3572 * gdb.texinfo (directory command): Doc new dir command.
3573 source.c (directory_command): "dir" now puts things on the front
3574 of the path, moves dups up front, and handles multiple names
3575 on the command line, inserting each one in order. It also
3576 blows away cached line and full_filename info.
3578 * stack.c (backtrace_command): Skip "more stack frames follow"
3581 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3582 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3583 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3584 The only odd one was Gould NP1, which had defined vprintf to
3587 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3588 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3589 variable, inspect_it.
3590 valprint.c (print_string, val_print): Use the global inspect_it
3591 to indicate whether to print in Epoch style or normal style.
3593 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3595 * printcmd.c (call_command): add an alias for the "print" command
3596 which runs expressions and doesn't print the result if void.
3597 (print_command_1): implement it.
3599 * command.c: Remove #if 0'd code. Initialize all the fields
3600 in add_cmd (). Rename do_nothing_command to
3601 not_just_help_class_command, and make it externally visible.
3602 command.h: add user_commands to struct.
3603 * main.c (define_command): Don't overload c->function with a char
3604 string as well as a function pointer.
3606 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3607 calling convention of value_struct_elt () that got dropped in
3610 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3611 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3613 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3615 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3616 until a good time (e.g. when we are about to run the child),
3617 saving ptrace calls.
3618 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3619 * tm-sparc.h: define DO_DEFERRED_STORES.
3621 * sparc-xdep.c (store_inferior_registers): when storing float
3622 registers, don't store stack regs too. When storing the SP,
3623 however, DO store the stack regs too. This fixes a bug in which
3624 the dummy frame is not recognized when a call_function finishes,
3625 because its frame pointer (in the stack regs) was never
3627 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3628 even though we don't know how to read them from an inferior.
3629 valops.c (call_function): Comment about storing SP.
3631 * infrun.c (save_inferior_status): Save away the original bpstat
3632 chain so it can be restored later. Install the copied version for
3633 use by whoever saved the status. It will be blow away by
3634 restore_inferior_status, and the original chain restored. This is
3635 important for people who have pointers into the original.
3637 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3638 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3639 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3642 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3644 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3645 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3646 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3648 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3650 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3651 Store the baseclasses in a type struct starting from array element
3652 0 rather than from the unusual array element 1.
3654 dbxread.c: the above.
3655 (virtual_context): Add
3656 Read new debug information about which virtual function table
3657 a virtual function is from, and store it in fn_field.fcontext.
3659 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3660 TYPE_FN_FIELD_STATIC_P.
3662 symtab.c: the above.
3663 valops.c: the above. Handle pointer casts of object *'s.
3664 (search_struct_method): Add.
3665 (value_struct_elt): First arg is now a pointer to a value, and is
3668 valprint.c: the above.
3669 values.c (value_virtual_fn_field): Add type arg. Handle
3670 offsetting to the proper object when calling virtual fns.
3672 (baseclass_addr): Add valuep arg.
3674 * README: Document the current state of BFD config (missing).
3675 * TODO, ChangeLog, Makefile.dist: Roll version.
3676 * WHATS.NEW: Add summary of changes since 3.5.
3678 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3680 * dbxread.c (read_struct_type): Clear bit vectors whenever
3682 symtab.c (B_CLRALL): define.
3684 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3685 using == rather than =. Huh... This fixes the dreaded problem
3686 wherein builtin_type_int becomes TYPE_CODE_FLT.
3688 * core.c (info_files): Show the inferior pid.
3690 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3691 already knows how to look in the source directory.
3693 * Remove psymtab hair from many places. Remove duplicated code
3694 for searching symbol tables. Hide psymtabs from most places.
3695 Make it fast to get from a psymtab to its symtab.
3697 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3698 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3699 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3700 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3701 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3702 new symtab completely. New psymtabs get symtab pointer
3703 initialized to zero. Remove MI warning printf.
3704 symtab.h: Comments. Add psymtab to symtab pointer.
3705 (PSYMTAB_TO_SYMTAB): New macro.
3706 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3707 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3709 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3711 (print_frame_info): Avoid special-casing symbols that have not yet
3714 * source.c (open_source_file): Quick path if we have already
3715 located the source file by its full name.
3717 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3718 find_pc_psymtab. When a name is found in the misc function
3719 vector, search the symbol table for its mangled name, not the
3720 name that the user typed.
3722 * bfd.h: Fix missing comment terminators, make #endifs match.
3724 * valarith.c (value_less): Handle unsigned int comparisons.
3725 Add FIXME about pointer compares, which assume host and target
3726 pointers are the same.
3728 * command.c (do_nothing_command): lint
3729 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3730 fix comments on debug symbol format for visibility. Actually set
3731 visibility of symbols.
3732 main.c (echo_command): lint; use <readline/history.h>.
3733 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3734 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3735 pointing past end of allocated memory; saber complains.
3736 obstack.h: Declare the external functions that we use.
3737 valarith.h: use <string.h>
3738 solib.c (solib_add): lint.
3740 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3742 * main.c (initialize_main): Default info_verbose to off, now that
3743 symbol reading is fast.
3744 (quit_command): Avoid clobbering exec_bfd while quitting.
3746 * Initial BFD (binary file diddling library) merger:
3747 coffread.c: Change AOUTHDR to struct exe_hdr.
3749 core.c: initialize initialized data at compile time.
3750 (core_file_command): Move from coredep.c, convert to bfd.
3751 (xfer_core_file): Convert to bfd.
3752 exec.c (exec_file_command): use bfd routines.
3754 mips-tdep.c: Remove exec_file_command and friends.
3757 * coredep.c: (fetch_core_registers) Convert core_file_command to
3758 fetch_core_registers.
3759 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3761 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3762 (my_bfd_read): More bogosity, which I don't think we call.
3763 (program_name): Remove this atrocity asap!
3765 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3768 values.c: allocate_repeat_value was not clearing the
3769 optimized_out field.
3770 (value_static_field): minor stylistic fix (wrong macro was used).
3771 valops.c (value_struct_elt_for_address): didn't work for C++
3774 * signame.c (_initialize_signame): Initialize signal names once.
3776 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3777 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3778 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3780 * remote-eb.c: Support user-settable baud rates on the serial port.
3782 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3784 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3786 * tconfig/sun3os4: Remove warning about native assembler,
3787 since it also occurs in the xconfig file.
3789 * findvar.c (registers): Allocate some slop after `registers'
3790 to prevent stray accesses from trashing the next variable.
3792 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3793 on the sun-3, by changing the #ifdef from `sun3' (which is not
3794 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3795 vars, which happened to follow `registers' in the executable.
3797 * readline/history.c (history_search): Heed gcc-2's advice
3798 and parenthesize && inside ||).
3800 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3801 tm-29k.c: Insert FSF copyright headers.
3803 * remote-eb.c: Better comments.
3805 * Makefile.dist: Update to 3.91.6.
3806 * TODO: note PREPARE_TO_STORE problem.
3808 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3810 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3812 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3814 * infrun.c (wait_for_inferior, at end): Don't set up
3815 prev_* if the inferior no longer exists.
3817 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3818 CANNOT_EXECUTE_STACK.
3819 valops.c (call_function): Use it.
3821 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3823 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3824 infrun.c (wait_for_inferior, 2 places): Use it.
3826 * values.c (value_being_returned): Only use
3827 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3829 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3830 right thing for remote-eb.c.
3832 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3833 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3835 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3836 (FRAME_FIND_SAVED_REGS).
3838 * findvar.c ({fetch,store}_registers): Check for
3839 REMOTE_{FETCH_STORE}_REGISTER macro.
3841 * findvar.c (get_saved_register): Add argument lval and
3842 change meaning of argument addr.
3843 findvar.c: Change calls to get_saved_register to reflect
3844 new calling convention.
3845 valops.c (value_assign): Use get_saved_register instead of
3846 find_saved_register.
3848 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3850 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3851 an (uninitialized) pointer to one. Use "&" when passing it
3854 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3856 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3859 * coffread.c (symbol_file_command): Put semicolon after
3861 Put safe_to_init_tdesc_context in #if defined (TDESC).
3862 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3863 coffread.c: #include <sys/stat.h>.
3864 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3865 Add missing ')' in check for "lc%" and friends. Remove
3867 Declare read_one_sym() at top of file.
3868 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3869 MC68WRMAGIC can have the same value without causing a duplicate
3872 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3874 * Allow a Makefile to be built without building the
3875 tm and xm file links that screw up builds in subdirectories.
3876 This is done with `config.gdb none', then you can do things
3877 like `make gdb.tar.Z'.
3878 * tconfig/none: Config file for no target system
3879 * xconfig/none: Config file for no host system
3880 * config.gdb: If no TM or XM files are called out by the
3881 host or target file, don't make links for them.
3883 * cplus-dem.c: Add documentation.
3885 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3886 simple error, so the user's gdb doesn't crash due to some object
3887 file problem (e.g. somebody is rebuilding the file out from under
3890 * printcmd.c (print_address_symbolic): demangle the symbol.
3892 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3893 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3894 (alldeps.mak): sort and uniq all results from this; duplicates
3895 hose gdb.tar.Z link building. Remove RCS files from
3896 tconfig and xconfig. Add config files for sun386. Add
3897 a few odd files to OTHERS and HFILES.
3899 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3901 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3902 Roll version number to 3.91.5. Make lint work in bindir.
3904 * README: Document cross-debugging and new file structure.
3906 * blockframe.c: Lint. Include "value.h" to declare read_register.
3907 (find_pc_partial_function): remove duplicate line.
3909 * command.h: Lint. Declare error_no_arg and dont_repeat.
3911 * tm-news.h: Remove inadvertently duplicated stuff.
3913 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3914 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3916 * config.gdb: Allow `config.gdb host target' form. Clean
3917 up previous change that printed bogus messages when you just said
3920 * core.c: #include "command.h" for lint.
3923 * main.c: Remove some casts of enums. Lint.
3930 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3932 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3933 read it from memory. This will allow us to save ptrace calls
3934 eventually. Changed caller single_step too.
3936 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3937 that we aren't going to use, saving many ptrace calls, especially
3938 when watchpointing or single stepping. Use some #define's for
3940 (store_inferior_registers): Ditto.
3941 (core_file_command): Use some #define's for constants.
3943 * tm-sparc.h: Add #define's for some register numbers, so we
3944 can eliminate the use of random constants in sparc-xdep.c.
3946 * stack.c (frame_command, print_frame_info, up_command,
3947 down_command) Remove frame_changed, since it
3948 causes a bug and doesn't seem to do anything useful. In some
3949 places it was used as a flag, in others as a stack level (?).
3951 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3952 default is to use the portable (vprintf) version rather than the
3954 * xm-news.h (MISSING_VPRINTF): Add.
3956 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3958 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3960 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3961 about linking debugged programs -Bstatic in the sun?os4 config
3962 files in tconfig and xconfig subdirectories.
3964 * main.c (main): Remove unreached exit(0) now that we exit
3967 * Create TODO file for online bug list. There are too many
3968 "little" bugs to keep track of on paper.
3970 * Change Projects file to refer to bug-gdb@cygnus.com
3971 rather than kingdon@ai.
3973 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3975 * Makefile.dist (VERSION): 3.91.4 now.
3977 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3978 (condense_misc_bunches): Add sanity check that misc_count is
3979 the same as the number of symbols in the bunch.
3981 * coffread.c: rename init_misc_bunches. Pass an argument
3982 to condense_misc_bunches (a zero).
3984 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3985 every time we are called; don't rely on our caller to do it.
3986 (add_file): Remove call to init_misc_bunches.
3988 * mipsread.c: Only warn, don't error, if unknown symbol types.
3989 This keeps an old gdb from falling on its face if it sees newly
3990 extended symbol info. Rename init_misc_bunches.
3992 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3994 * Merge in changes from Per Bothner for DECstations and other
3995 MIPS stuff. The rest is Bothner speaking:
3997 The next message is a merger of Alessando Forin's mips port with
3998 mine. I've tried to use my good if biased judgment to get
3999 the best of both. It *does* need testing.
4001 Some of the changes are general, *not* mips-specific.
4004 Didn't believe in little-endian bit order.
4005 There are still inconsistencies about whether flags
4006 like BITS_BIG_ENDIAN are integer (#if ...) or
4007 boolean (#ifdef ...). I tried to paper over them.
4009 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
4010 Moved some misc_function code that was common to
4011 {dbx,coff,mips}read.c to symtab.c.
4012 In the process, I think I cleaned things up a bit.
4013 At the same time, moved obsavestring and obconcat to symtab.c.
4016 Removed obsolete condense_addl_misc_bunches (use
4017 condense_misc_bunches(1) instead).
4020 Needed to include <sys/dir>, at least on DECstations.
4022 valops.c, mips-tdep.c, tm-mips.h:
4023 Added PUSH_ARGUMENTS macro to support funny argument-pushing
4024 conventions (when STACK_ALIGN is insufficient).
4025 Needed on mips, where doubles need 8-byte alignment,
4026 but ints only need 4.
4029 Removed cruft that was not being used.
4030 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
4033 Print $ before register-names (I think that makes things a little
4035 Never print two instructions, even if one delays.
4036 Removed hex-disassemble set_cmd. (This is not mips-specific,
4037 so I think the argument is whether it is generally worthwhile or not.
4038 I'm inclined to think not, given how easy it is to
4039 convert between radixes in gdb.)
4042 This is basically Alessando's code.
4043 It doesn't use obstacks; I changed it to use obstacks
4044 in a few minor places where using malloc causes a
4045 memory leak. (Probably, more places could/should be changed.)
4046 I added record_misc_function where it was missing.
4047 In symbol_file_command and add_file_command, I tried
4048 to make the code consistent with more recent versions.
4049 Minor sylistic changes in parse_procedure.
4050 Make a .gdbinfo. psuedo-symbol point back to the real
4051 procedure symbol (using the isym field).
4054 This is basically from my port, but with a lot of details
4055 and a number of routines merged in from Alessando's version.
4056 I basically used my code "raw" backtrace (use heuristics
4057 from the actual code, rather than symbol table info) - though
4058 the idea is Alessandro's. I feel my code is a little cleaner
4059 here, particularly in being a little more flexible, such as being
4060 able to handle gcc-produced code (which it now can).
4061 It also doesn't do frame caching (which is not useful
4062 more recent gdb versions).
4063 I also used my code for push_/pop_dummy, more or less.
4064 I tried to incorporate AF's code for testing sigtramp
4065 while backtracing; I probably got it wrong.
4066 Added mips_print_register, which tries to scrunch as much
4067 information as possible on a screen...
4068 Removed the skip-prologue set_cmd. As with hex-disassemble (see
4069 under mips-pinsn.c), I don't see anything mips-specific here,
4070 and I don't see it being all that useful anyway.
4073 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
4074 Use more register names (rather than hard-cases numbers).
4076 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
4078 * Hack up 3.90.11 changes:
4080 * Makefile.dist (depend): parameterize $(GCC).
4081 Add solib.c and solib.o.
4082 (readline): Fix vpath for both absolute or relative SRCDIR.
4084 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
4085 Also, let the part I didn't understand at least compile so
4086 I can test the rest. FIXME.
4088 * dbxread.c: Fix thinko using strcmp.
4089 (init_psymbol_list): declare static.
4090 (partial_symbol_file_open): Comment cleanups better, avoid
4091 cleaning up the string table since the caller will do that.
4092 Move the stat for mod time into symbol_file_command, temporarily.
4093 (There should be a mod time for each symbol file, eventually,
4094 to control its rereading. FIXME.)
4096 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
4097 SunOS, which gives error for shared libs otherwise. (From
4098 Schaefer, probably FIXME needs work for portability.)
4100 * solib.c: Move #include "param.h" to work.
4101 Lowercase all the Uppercase Letters In the Messages.
4102 (find_solib): Clean up inferior_so_name for debug printouts.
4103 Allow no argument, to mean all shared libraries.
4105 * symmisc.c: include param.h to get CLEAR_SOLIB.
4107 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
4109 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
4110 to 3.90.11. ChangeLog entries below are from this.
4112 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4116 * Makefile.dist (HFILES): Add tm-sunos.h.
4118 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4122 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
4124 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
4126 * sparc-opcode.h Added single-operand version of rett.
4128 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4130 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
4131 Put parens around gcc_p in expansion.
4133 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4135 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
4137 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4139 * Changes for Sun shared libraries:
4140 blockframe.c (find_pc_partial_function): If a non-text symbol
4141 is found, set *address = pc - FUNCTION_START_OFFSET.
4142 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
4143 Disable breakpoints instead of giving an error.
4144 source.c (select_source_symtab): Initialize cs_pst.
4145 symmisc.c: Call CLEAR_SOLIB if defined.
4146 symtab.h: Make text{low,high} CORE_ADDR not int.
4147 (psymtab): New field addr.
4149 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
4150 (record_misc_function): Give correct type for N_DATA symbols.
4151 (condense_misc_bunches): do "misc_function_count = j" regardless
4153 Take code which is shared between symbol_file_command and
4154 add_file_command and put it into partial_symbol_file_{open,read}.
4155 Split add_file_command into add_file_command and add_file.
4156 Make psymtab_to_symtab read in the string table if the file
4158 Two new parameters to read_dbx_symtab and start_psymtab.
4159 tm-sunos.h: New file.
4161 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4163 * infcmd.c: Change cont_command to continue_command and "cont"
4166 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4168 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
4170 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
4172 * values.c (USE_STRUCT_CONVENTION): Check for structures of
4173 size 1,2,4,8 rather than size < 8.
4175 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
4176 as necessary, not just once.
4178 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
4180 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4182 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
4184 * tm-news.h: Add CALL_DUMMY_*.
4186 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
4188 * config.gdb: In list_host, list_target, use ${i}, not $i.
4190 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4192 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
4194 * sparc-opcode.h: Change all store floating-point state register
4195 instructions to have the right match & lose fields.
4197 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4199 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
4201 config.gdb: If srcdir != ., create readline directory and
4202 copy a makefile into it.
4204 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
4205 consistency with POSIX.
4207 * breakpoint.c (bpstat_stop_status): Disable watchpoint
4208 when we exit its exp_valid_block.
4210 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
4212 * Makefile.dist: Bump version to 3.91.3.
4214 * Clean up handling of breakpoint commands (somewhat).
4215 Prompted by Tiemann bug report "cont 10" doesn't work any more.
4217 inferior.h: Add breakpoint_proceeded to inferior status struct
4218 and globals; save it and restore it.
4219 (clear_breakpoint_commands): Cleanup, remove old #define.
4221 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
4222 (save_inferior_status, restore_inferior_status): handle it also.
4223 (proceed): Remove earlier code that set breakpoint_proceeded.
4224 It is now set only in clear_proceed_status.
4225 (clear_proceed_status): Cleanup, use bpstat_clear rather
4226 than clear_breakpoint_commands. No callers need the stop_bpstat
4227 between clear_proceed_status and proceed.
4229 infcmd.c: Add breakpoint_proceeded definition and comment.
4230 (cont_command, jump_command, signal_command): Move call to
4231 clear_proceed_status right next to call to proceed.
4233 breakpoint.c (bpstat_do_actions): Avoid clobbering our
4234 caller's argument while running down the chain of breakpoints.
4235 Use new variable "breakpoint_proceeded" to determine when
4236 a command that it executes moves the inferior past the
4238 (bpstat_clear): Handle NULL argument.
4239 (bpstat_clear_actions): Avoid useless call to
4240 breakpoint_auto_delete.
4241 (delete_breakpoint): Clean up bpstat's that are pointing to
4242 the deleted breakpoint from the stop_bpstat chain.
4243 (breakpoint_auto_delete): Simplify.
4245 * Clean up handling of EOF, error on stdin, etc. This was
4246 prompted by a network problem that caused gdb to go into an
4247 infinite loop filling up its malloc'd memory.
4249 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
4250 not clear_breakpoints_commands, which is now gone.
4251 (main): If command_loop returns (e.g. from EOF on stdin), do
4252 a quit_command (looping back to command_loop if quit_command
4253 doesn't really quit).
4254 (command_loop): check result from command_line_input and
4255 exit if it returns NULL, rather than passing the NULL to
4257 (gdb_readline): Free malloc'd result space before returning
4260 * utils.c (query): Handle C-d to mean "yes", just as if the
4261 input was not a terminal. Also avoid infinite loop if EOF
4262 occurs in mid-input-line before newline. This allows
4263 query to be used at EOF on stdin with reasonable results.
4265 * infrun.c (proceed): Set breakpoint_proceeded.
4267 * values.c (value_as_long): Avoid infinite recursion for enums.
4268 (_initialize_values): Fix typo in help msg (kingdon).
4270 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
4271 RL_LIB for linking. This allows -lreadline for linking
4272 and nothing for dependencies, once readline is a real library.
4274 * config.gdb: Jim Kingdon: give useful error message if the
4275 host or target type is not recognized.
4277 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
4278 it just defines it. Dumb, but deal with it.
4280 * Jim Kingdon suggests:
4281 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
4283 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
4285 * Makefile.dist (VERSION): Bump version # to 3.91.2.
4287 * Clean up Bothner's changes.
4289 * blockframe.c (clear_pc_function_cache): New function.
4290 * blockframe.c: remake cache_pc_function_* static.
4291 * dbxread.c (symbol_file_command): remove references to
4292 cache_pc_function_* variables.
4293 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
4294 * printcmd.c: Avoid kludging a global variable (addressprint)
4295 to avoid printing the address of a string twice. Instead,
4296 pass the format letter 's' down low enough that it can be seen
4297 to avoid this problem.
4298 (print_formatted): Pass format arg to value_print.
4299 (restore_addressprint): Remove function.
4300 (do_examine): Avoid hacking addressprint, cleanups and such.
4301 (print_frame_args): Add a comment to a Bothner change.
4302 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
4303 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
4304 to wipe out the values cached in blockframe.c.
4305 * symtab.c (find_method): Add comment saying how big you must
4306 allocate to be "big enough". Per being terse again.
4307 * valprint.c (val_print): Handle format letter "s" to print
4308 strings without addresses. Add comment to vtbl printing code
4309 which casts with wild abandon. Rearrange reference-printing
4311 @0xaddr: value (print w/addressprint)
4312 value (print w/~addressprint)
4313 @0xaddr (parameter lists w/addressprint)
4314 or nothing (parameter lists w/o addressprint)
4316 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
4318 * Merge more changes from Per Bothner:
4320 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
4321 annoying) that I tried to improve it. Here are my suggestions.
4323 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
4326 Do automatic de-reference when taking the address of a reference.
4328 Don't deref_ref when printing parameter lists.
4330 More attempts at treating refernences properly.
4332 In val_print, if deref_ref==0, don't print dangling " = ".
4334 Add COERCE_REF macro, which de-references an REF.
4336 * Merge changes from Per Bothner:
4338 * Fixed (Sony news)-specific configuration problems.
4339 * Fixed other problems with using vanilla pcc and libc (enum problems;
4340 assumption that vsprintf exists).
4341 * Some major speed-ups (finc_pc_partial_function now caches a match;
4342 parsing avoids duplicate symbol_lookup calls).
4343 * Changed handling of baseclasses (no longer use baseclasses field
4344 of struct type, use the first n_baseclasses fields instead).
4345 * Various minor changes/fixes, most C++-related.
4348 Cache the most previous match from find_pc_partial_function.
4349 (Save both low and high ends of matching function's pc range.)
4350 This speeds up the loop of infrun.c:wait_for_inferior quite
4351 a bit, and makes step/next commands much zippier.
4353 Added an enum->int cast (otherwise, some compilers barf).
4355 No longer set baseclass offset to 0, since multiple
4356 inheritance now mostly works.
4357 Added a number of casts, to shut up compiler warnings
4358 (after stabs where made enums, not ints).
4359 When discarding a symbol table (in symbol_file_command),
4360 must clear the cache introduced in blockframe.c.
4361 Don't convert $vtbl_ptr_type to vtbl any more.
4362 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
4363 Mask off sign bit emitted by g++ for virtual table offset.
4364 Set voffset to -1 (not 1) for static member functions.
4366 Changed parsing/lexing of names to avoid doing symbol lookup twice
4367 (once when lexing to determine symbol class, once for real).
4368 Now only call symbol_lookup once. Fields of 'this' win especially big.
4370 Subpress printing addr twice in the case of 'x/s addr'.
4372 lookup_basetype_type is no longer used.
4373 Add find_methods as recursive helper function to decode_line_1.
4374 This allows multiple inheritance to work.
4375 Also, once one or more matches has been found, do not look in
4376 base-classes. (Baseclass methods would be overridden, anyway.)
4378 Removed baseclasses array in struct type.
4379 Instead of using baseclasses[i], use fields[i-1].
4380 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
4381 Changed sign convention of voffset (previous was inconsistent).
4383 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4385 Used to assume existence of vsprintf. Re-written to not need it
4386 if HAVE_VPRINTF is undefined.
4388 typecmp was too pessimistic. Made it less so.
4390 Don't print space after address.
4391 If vtable points to a misc symbol (with 0 offset), print it,
4392 since that indicates the actual class of the object.
4393 Changed ype_print_derivation_info to use new inheritance
4394 scheme (without baseclasses vector).
4396 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4397 Also, changes needed because TYPE_BASECLASSES were removed.
4399 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4401 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4404 If there is no path set, and the symbols don't indicate what directory
4405 a file was compiled in, look in the current directory. But either
4406 a path or a known compilation directory will prevent this.
4409 Three independent bug fixes:
4410 * Remove the #if 0 block that breaks some stuff.
4411 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4412 adapt gdb to either SunOS 4.0.* or 4.1.
4413 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4416 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4419 (type_print) Demangle the name being printed.
4420 (type_print_base) Handle botched demangling without coredump (tiemann).
4423 (check_stub_method): Document routine.
4424 (tiemann) fix bug for no-arg functions
4425 Avoid clobbering beyond end of malloc'd storage.
4426 Terminate the argument list properly.
4428 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4430 * Changes merged by John Gilmore:
4433 In breakpoint_1, use new print_address_symbolic instead
4434 of find_pc_partial_function. (This forces use of assembler-level
4435 addresses, and avoids misleading non-mangled source-level names.)
4437 Generalize ansi argument such that -1 means skip arglist totally.
4438 Removed global variable print_ansi_qualifiers (which made
4439 code non-reentrant), in favor of extra explicit arguments
4440 to internal routines.
4442 Add new helper function print_address_symbolic.
4443 Use find_pc_misc_function instead of find_pc_partial_function
4444 (since we want assembler-level symbols here).
4446 Print unknown function as just "f (...)", not "f (...) (...)".
4447 Use new fputs_demangled explicitly.
4449 Fixed a typing violation (problem: value.h cannot be imported
4450 without renaming many variable in this file).
4451 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4452 decode_line_1: Moved forward some never-reached code.
4453 Made decode_line_2 skip function prologues correctly.
4455 fputs_filtered should not demangle by default.
4456 Add new fputs_demangled to demangle on demand..
4458 Change value_struct_elt to use value_primitive_field (using recursive
4459 utility function search_struct_field). This allows foo.bar to work
4460 for multiple inheritance (so far only for data fields).
4461 Change check_field in the same way (recursive helper function
4462 to support multiple inheritance).
4463 (Note: there are more of these problems that I haven't fixed.
4464 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4465 value_of_this: 'this' symbol name is now just "this", note "$this".
4467 Don't print static members.
4468 Avoid printing "members of <type>" if there are none.
4469 Simplified type_print_derivation_info by merging duplicate code.
4470 Remove useless blank lines in type_print_base (ptype command).
4472 Added declaration of new routine value_primitive_field.
4474 Added value_primitive_field which is generalized version of
4475 value_field that can handle multiple inheritance (non-zero offsets etc).
4476 Re-implemented value_field to call value_primitive_field.
4478 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
4480 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4481 delete the whole environment. Karl Berry reported the bug.
4482 * source.c - fix openp to avoid //'s in filenames, which
4483 trigger an Emacs bug causing it to not be able to find files
4484 when running gdb in a window.
4485 * dbxread.c - zap the #if 0 that botches the add-file code.
4486 It seems to work a lot better without all the code commented out.

4495 * Makefile - added a ${CFLAGS} to a couple of entries,
4496 added remote-sa.sparc.c
4497 * added remote.sa-sparc.c, a modification of remote.c
4498 which conducts a dialog directly with the SparcStation prom.

4500 remote_insert_breakpoint(), and remote_remove_breakpoint()
4501 to breakpoint.c instead of directly writing breakpoint instructions.
