1 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
3 * Makefile.in (VERSION): Update to 4.0.3.
5 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
7 * core.c (core_file_command): Print frame at coredump with
8 its level number, by calling print_stack_frame.
9 * frame.h: Add selected_frame_level, print_stack_frame.
10 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
11 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
12 Change print_sel_frame and print_selected_frame callers to
15 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
16 * symfile.c (free_named_symtabs): Ditto.
17 * main.c (main): wrap_here needs an arg.
18 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
19 (solib_add): Avoid noise.
20 (solib_create_inferior_hook): Lint.
21 (sharedlibrary_command): Move dont_repeat to here.
22 * utils.c (error): Call wrap_here to force buffered output.
24 Small patches from Peter Schauer:
26 * coffread.c (start_symtab): Free any existing line_vector before
28 (read_coff_symtab): Ditto for type_vector.
30 * source.c (lines_to_list): New variable, replacing function.
31 (all uses): Use as variable.
32 (_initialize_source): Add 'set listsize' and 'show listsize'.
33 * utils.c (lines_to_list): Remove function.
34 * stack.c (print_frame_info): Use as variable.
35 * defs.h (lines_to_list): Remove declaration.
37 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
39 * breakpoint.c (insert_breakpoints): Restore warning about
40 the program might be running in another process, but only for
41 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
42 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
44 * utils.c (error): if error_pre_print is set, print the string
46 * main.c (main, print_gnu_advertisement, print_gdb_version):
47 Reformat legalese so it always prints, but acts as an "I'm here"
48 message while symbols are being read. If any errors occur,
49 print a few newlines to set off the message and start it at the
50 left margin. Remove mention of "help" command, and don't yak
52 (catch_errors): Error string is now printed first in case of
54 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
55 suggest the "help" command.
57 * Makefile.in (VERSION): Set to 4.0.2.
59 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
61 * .gdbinit: Remove useless "rr" command. Set complaints
62 to 1 for people debugging gdb.
64 * breakpoint.c, remote-vx.c: Reword strings printed by
67 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
69 * WHATS.NEW: "history write -> history save". Doc "write on/off".
70 (Fix from kenc@viewlogic.com.)
72 Fix some infrastructure to be able to cope with host and target
73 machines with different sized basic types (ints, ptrs, etc).
74 (Idea from pierre@la.tce.com (Pierre Willard).)
76 * values.c (value_from_longest): Rename from value_from_long.
77 Handle pointer types as well as integers, so that targets with
78 different pointer sizes from the host can be accomodated.
79 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
80 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
81 uses of value_from_long to value_from_longest.
82 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
83 the correct pointer type to value_from_long{est}.
85 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
87 * remote-vx.c: Remove obsolete code for calling functions via
88 vxworks kludge interface (it referenced value_from_long).
90 * valops.c (value_string): Find malloc with lookup_misc_func, not
93 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
95 Make writing to files work properly. (Fixes to BFD are also needed.)
97 * core.c (core_open): Open file ourselves, read or r/w, depending on
98 write_files. Use bfd_fdopenr.
99 * gdbcore.h (write_files): New variable.
100 * exec.c (write_files): Define variable, add set&show for it.
101 (exec_file_command): Use write_files to open for read or r/write.
103 Make shared library reading happen automatically. These changes
104 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
106 * inferior.h (stop_soon_quietly): Add to exported variables.
107 * infrun.c (child_create_inferior): call solib hook, if defined.
108 (child_attach): call solib hook, if defined.
109 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
110 (find_solib): Use lookup_misc_func rather than hand-rolled.
111 (symbol_add_stub): New stub for catch_errors.
112 (solib_add): Avoid output if !from_tty. Catch errors rather
113 than just calling symbol_file_add and bombing.
114 (solib_create_inferior_hook): Interface with the target process
115 to let it read and alloc shared libs, then figure out what it did.
117 * core.c (validate_files): Fix typo, soften warning.
118 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
120 * utils.c (fputs_demangled): Avoid duplicate printing if
121 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
123 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
124 (Fix from pierre@la.tce.com (Pierre Willard).)
126 * main.c (catch_errors): Change argument to a char * from an int,
127 since a char * can point to a struct full of glop, but an int
128 is not guaranteed to be able to hold a pointer.
129 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
130 breakpoint_re_set_one, breakpoint_re_set): Adapt.
131 * core.c (core_open, solib_add_stub): Adapt.
132 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
134 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
136 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
137 by adding .NOEXPORT target.
139 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
143 * Makefile.in (VERSION): Roll to 4.0.
144 (gdb.tar.Z): Make refcard.ps as well, for shipment.
146 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
148 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
151 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
154 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
156 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
157 reflect above name change
159 * WHATS.NEW: correct pointer to refcard.
161 * doc/gdb.texinfo: update New Features, Installing
163 * doc/gdbint.texinfo: add short description of configure +template
165 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
167 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
169 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
171 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
172 tar file, add dependencies for referenced doc files.
174 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
176 * coffread.c, symfile.c, stack.c: saberized.
178 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
180 * doc/refcard.tex: permuted Essential Commands sec
182 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
184 set/show symbol-reloading
185 default set complaints 0
187 RET-repeat disabled after prompted long displays
188 processID (attach) interpretation of 2nd GDB cmdline arg
190 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
192 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
193 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
194 breakpoint.c, main.c: lint.
196 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
198 Install new configuration scheme for GDB and friends.
200 * config.sub: Translate ordinary names to three-part names.
201 * configure: Use three-part names internally.
202 * configure.in: Translate three-part names to filenames.
204 * README, WHATS.NEW: Update for gdb-4.0.
205 * Makefile.in: Roll VERSION to 3.99.
207 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
209 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
210 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
211 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
212 to single structures rather than arrays; when passing
213 their address, use &. This avoids trouble with bdead compilers.
214 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
215 instead. This avoids portability headaches.
216 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
218 * source.c (open_source_file): Avoid ANSI const bdeath by
219 skipping declaration and then casting result value.
220 * tm-hp300bsd.h: Clarify comment.
221 * utils.c (strstr): Result is const char *; ANSI bdeath.
222 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
223 since system include file defines it differently from "defs.h",
224 though the two are equivalent for our purposes.
225 * tconfig/hp300bsd: Add m68k-tdep.o.
227 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
229 * tconfig/sun*4: Remove warnings about system assembler.
231 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
233 * mcheck.c: Avoid warning about undeclared abort fn.
234 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
235 it causes recursive calls to error() when used in cleanups.
236 To do so requires that we make it a function, so we do.
237 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
238 * utils.c (do_cleanups): Remove the current cleanup from the
239 chain *before* calling it, in case error() is called from it.
240 The result won't be pretty, but won't be an infinite loop either.
242 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
244 * dbxread.c (read_struct_type): Grok anon structs for C++.
245 (vb_name, vptr_name): Null terminate these strings.
247 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
249 Minor bug fixes from BSD Net2 gdb:
251 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
252 returns 0, there is no previous frame.
253 * breakpoint.c (commands_command): If !from_tty, don't call
254 input_from_terminal_p().
255 * dbxread.c (record_misc_function): Speed up slightly.
256 (compare_psymbols): Ditto.
257 * infcmd.c (do_registers_info): Take a second argument to
258 determine whether to print float registers. "info registers"
259 does not do so anymore. "info all-registers" does, now.
260 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
262 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
263 * inflow.c (initialize_inflow): Set tflags_ours correctly.
267 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
268 executing_breakpoint_commands if we are interrupted by error.
269 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
270 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
271 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
272 catch_errors() so we can setup the frame regardless of whether
273 the shared libs work.
274 * ieee-float.c (double_to_ieee_extended): Get exponent from
275 right place in little-endian systems. From John Carey.
277 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
279 * main.c: Remove unused terminating_signals and catch_termination().
280 (long_options): Terminate with a zero element.
281 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
282 (gdb_readline): Make call-compatible with readline.
283 (init_signals): Improve comments re vfork vs. signal.
285 * utils.c (prompt_for_continue): Use new gdb_readline().
286 If we prompt for continuation, we don't let CR repeat the previous
287 command, once we get back to a prompt. It's too easy to keep
288 hitting CR, expecting "--more--" prompts, and have some long
289 command start repeating on you.
291 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
293 * blockframe.c (frameless_look_for_prologue): Speed up by
294 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
295 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
296 Define two variants, one faster.
297 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
298 and return zero, rather than giving an error.
299 (setup_arbitrary_frame): Initialize the PC in the new frame.
300 (skip_prologue): Add a second arg saying whether we're just
301 checking for a frameless function or not.
303 * core.c (core_open, core_close, core_xfer_memory): Move
304 section table pointers and bfd* into the target_ops.
305 (core_open): Allow errors in shared lib reading, etc.
306 (core_files_info): Describe shared library sections.
308 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
309 exec_files_info, set_section_command): Move section table
310 pointers and bfd* into the target_ops.
311 (add_to_section_table): Add BFD to section table.
313 * target.c (target_xfer_memory, target_info): Pass target to
314 xfer_memory and target_info functions.
317 * gdbcore.h: Move struct section_table.
318 * target.h: New home of struct section_table.
320 * solib.c (solib_add): New argument is the target_ops whose
321 section list is to be added to, if any. Reallocate the
322 sections in that target to add any that come from shared libs.
323 (throughout) so_sections renamed to sections.
324 (solib_xfer_memory): Deleted.
325 * tm-sunos.h (SOLIB_ADD): Add target argument.
326 (SOLIB_XFER_MEMORY): Delete.
328 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
329 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
330 from target_ops. It's the same on all targets. Add two section
331 pointers to target_ops.
333 * stack.c (find_relative_frame): Dump ancient algorithm for
334 "down", just use handy "next" pointers.
335 (frame_command): Don't error if there is no stack; let user
338 * inflow.c (new_tty_prefork, new_tty): New prefork routine
339 modifies static state in the parent process; new_tty itself
340 runs in the child and modifies the child's file descriptors
341 to match the saved static state.
342 * infrun.c (child_create_inferior): Call new_tty_prefork,
345 * infptrace.c (child_xfer_memory): Add ignored target arg.
346 * remote-eb.c (eb_xfer_inferior_memory): ''
347 * remote-nindy.c (nindy_xfer_inferior_memory): ''
348 * remote-vx.c (vx_xfer_memory): ''
349 * remote.c (remote_xfer_memory): ''. Rename from
350 remote_xfer_inferior_memory.
352 * main.c (main): Only try to attach "corefile" argument if
353 it starts with a digit.
355 * symfile.c (symbol_reloading): New "set/show" variable.
356 (symbol_file_add): Shorten message about symbol reading.
357 (add_symbol_file_command): Merge with add_syms_addr_command,
358 since this should work on all targets now.
359 (stop_whining): Default to zero, to shut up complaints
360 about bad symbol tables on many systems.
361 (free_named_symtabs): Just exit unless symbol_reloading.
363 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
364 and add comment explaining shared library screw.
366 * source.c: #if defined => #ifdef.
368 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
370 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
372 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
374 * doc/rdl-apps.texinfo: provide default readline-appendix finder
375 (doc/Makefile knows how to make one for local config)
377 * Makefile.in: use doc/Makefile for doc targets
379 * doc/Makefile: GDB documentation now has its own Makefile
380 doc/refcard.tex: renamed from "gdbrc.tex"
381 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
382 doc/gdbint.texinfo: add markup in "Cleanups" chapter
385 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
387 * values.c (baseclass_addr): When reading target memory, use the
388 length of the basetype, not the upper type. We've only malloc'd
389 enough space for the basetype, leading to errors in free().
391 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
392 ends up as a function specially, since we know the actual type of
393 the pointed-to address. This (somewhat) fixes display of
394 expressions that include misc_function_vector names. Try `cond 1
395 !strcmp("a","b")' then `i b'.
397 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
398 The child can be proceeded from inside wait_for_inferior in
399 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
400 getting skipped in that case.
402 * expprint.c (print_subexp): Use filtered output, since the
403 subroutines we call use it, otherwise the output is horribly
404 mangled, since output of wrappable stuff comes out late.
406 * Makefile.in: Bump VERSION to 3.98.1
408 * infrun.c (child_create_process): Use execlp to find the
409 shell to exec our target program. This requires some fiddling
410 with `environ' since there is no execlpe().
412 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
414 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
415 Minor rearrangement of refcard permits two new make targets--
416 gdbrc.dvi DVI output for refcard, using CM fonts
417 gdbrc.ps PostScript refcard, using PS fonts
419 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
423 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
424 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
426 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
428 * doc/gdb.texinfo: last changes for release.
429 Minor typo and formatting fixes; incorporated most fixes remaining from
430 filed mail commenting on earlier drafts.
432 Added warnings: pipes don't work in run command;
433 conditions are converse of assertions;
434 step over fn without debug info goes to next fn;
435 vars may have "wrong" values near fn entrance, exit
437 Added example from Kingston on printing repeated nonadjacent values
439 Added explicit mention that in Emacs gdb mode C-c and C-z are like
440 shell mode for signals
442 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
443 doesn't sound so much like its parent "Stopping and Continuing"; also
444 moved entries on continue to top of section, so they don't get lost.
446 Improved installation directions in appendix, added manual formatting
449 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
451 * configure.in: Remove xm.h and tm.h even if we aren't linking
452 new ones, so "./configure sun4; ./configure none" does the right
453 thing. Assume that alldeps.mak and depend are already built in
454 srcdir, and avoid running "make" (particularly "make depend",
455 which involves "gcc") from inside configure. Build Makefile
456 directly rather than building Makefile.conf first.
457 * configure: Regenerate with above changes.
458 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
459 to 3.98. Revise gdb.tar.Z procedure to produce a file
460 called gdb-$(VERSION).tar.Z but which unpacks into a
461 directory called "gdb". Move non-source files out of
462 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
463 (depend): Don't try to do "gcc expread.y".
464 (expread.o): Update dependencies by hand.
466 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
469 Fixed a variety of small typos that prevented info from formatting
470 cleanly; altered too-long heading for GPL Appendix, as discussed
471 w/RMS; Changed date on cover to July 91.
473 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
476 (1) Applied some fixes due to comments from Larry Breed (easier ones
478 (2) Eliminated use of @footnote---had my doubts about it anyways, and
479 it's broken in latest texinfo
480 (3) Introduced *some* use of [] for optional arguments, where
481 explanation is not simpler by listing cmd w arg and cmd w/out arg
482 separately. Still not using @deffn.
483 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
484 couple of headings are too long. Need patches to texinfo or revision
487 * Partial update to README (which still needs work for this
488 release!): (1) use of configure corrected for new script,
489 (2) "make gdb.dvi" and "make gdb.info" mentioned.
491 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
493 * symtab.c (lookup_symbol): Don't complain right off about
494 no debug symbols; use the misc function vector first.
495 (list_symbols): Use misc function vector to find symbols
496 that don't have debug info, and print them.
497 (find_pc_symtab): Temporarily avoid fatal() when psymtab
498 PC range doesn't match symtab PC range, as it does on the
499 MIPS because our symtab reading isn't perfect.
501 * dbxread.c (dbx_symfile_read): Make warning about
502 "no debug symbols" slightly nicer.
504 * source.c (select_source_symtab): If "main" symbol exists,
505 but decode_line_spec can't find line info, don't just return
506 a zero; try other source symtabs or give an error.
508 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
509 their low addresses first, then rip through fixing high addrs.
511 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
513 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
515 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
517 * Minor, mostly mechanical, cleanup of doc subdir for clean
518 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
519 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
521 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
523 Mostly MIPS and general symbol-reading fixups.
525 * doc/gdbint.texinfo: Add documentation on symbol-reading
528 * mipsread.c: Remove kludges around #include "ecoff.h".
529 Remove redefinitions of a_magic, etc, no longer used.
530 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
531 Fix global overview comments to match symfile.c protocol.
532 (mipscoff_new_init): Eliminate cur_hdr if we have one.
533 (mipscoff_symfile_read): Eliminate unused code. Avoid
534 sorting all the symtabs, when all we have read here is psymtabs.
535 The symtabs are sorted as they are created anyway. Tell
536 condense_misc_bunches whether we're mainline.
537 (psymtab_to_symtab_1): Pass filename when recursing, to make
538 stack trace more informative.
539 (parse_partial_symbols): Assume cur_hdr as argument.
540 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
541 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
542 the TYPE_NAME of char *, since that's done in symfile.c.
543 (free_numargs, parse_symbol, add_symbol, add_block,
544 shrink_linetable): Declare these fns void.
545 (upgrade_type): Convert tree of if's to switch. Clean up
546 bogus "off == 0" handling with a complaint. Avoid setting
547 field bitpos and bitsize of array with lower and upper bounds.
548 Check specified bitsize of elements against their actual type's
549 bitsize, and complain if different. Complain about unknown
551 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
552 (psymtab_to_symtab_1): Print names of subsidiary files that
553 are being read in. FIXME, we read far too many files. This code
554 is not the problem, the problem is in parse_fdr where the psymtabs
556 (cross_ref): Result should indicate that we used one aux entry
557 normally, or two if we encountered a "next" entry. This used
558 to leave the caller pointing at the wrong aux entry.
559 (add_symbol): If overflowed cur_block, reallocate it larger,
560 chase all pointers to it, and complain(), rather than clobber memory.
561 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
562 (new_field): Only allocate one field initially, not two.
563 Pull ++ out of macro argument. Simplify.
564 (_initialize_mipsread): Avoid initialization of importd
565 global_psymbols and static_psymbols.
567 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
568 to properly set pst->symtab; avoid searching for it.
569 (symfile_fns): Improve comments, add a FIXME.
570 * dbxread.c: Update comments to reflect symfile protocol.
571 (read_ofile_symtab, end_symtab): Return the symtab.
572 (psymtab_to_symtab_1): Set pst->symtab.
574 * coffread.c (coff_symfile_read): tell condense_misc_bunches
575 whether we're mainline.
577 * symfile.h (sym_fns): Remove unused sym_discard member.
578 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
580 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
581 the environment variable is not.
582 * infcmd.c (finish_command): Use filtered printfs.
583 * cplus-dem.c: Add struct tags to a few unnamed structs.
584 * valops.c (value_coerce_array): Improve comments.
585 * valprint.c (type_print_varspec_suffix): Print array size only
586 if greater than zero.
587 * m88k-tdep.c: Shift some lines left by one space, that had
588 apparently been trashed at some point.
589 * TODO: More things to do, a few got done.
591 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
593 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
594 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
596 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
597 * expread.y, findvar.c, symmisc.c: Ditto.
598 * printcmd.c (address_info): Update printed forms of LOC_
599 symbols. Elim LOC_EXTERNAL.
600 (print_frame_args): Keep track of param stack offsets before
601 re-looking up to find the local register param is kept in.
603 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
604 Further integration of mipsread into gdb. Eliminate unused
605 routines, duplicate declarations. Handle static symbols in
606 psymtabs as well as external symbols. When reading symtabs,
607 insert symbols into the correct block (global, static, or a local
609 (read_mips_symtab, parse_partial_symbols): Don't pass useless
611 (mipscoff_symfile_read): Don't call select_source_symtab.
612 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
613 rather than SYMBOL_VALUE.
614 (parse_external): Comment clobbering of top_stack.
615 (parse_partial_symbols): Update comments. Allocate and parse
616 static symbols as well as external symbols. FIXME, enum values
617 are not handled in this pass, but should be. Inline new_psymbol.
618 Use SYMBOL_VALUE_ADDRESS.
619 (psymtab_to_symtab_1): Read symbols into global static block
620 by default (until enter some function's local block context).
621 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
622 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
624 * source.c (select_source_symtab): Select a source symtab
625 from either the symtabs or, failing that, the psymtabs.
626 (list_command): Update error message.
627 (forward_search_command, reverse_search_command): Use getc, not
628 fgetc, for speed. FIXME, add comment about buffers that die if
629 overrun by long line.
631 * values.c (unpack_field_as_long, modify_field): Avoid shifting
632 by an entire word, which is not portable, if we have a 32-bit
633 field. (Code in dbxread.c already turns such bitfields, if
634 aligned, into ordinary ints, but fixing this will help for other
635 symbol formats and for future changes.)
636 * core.c (core_open): Handle ANSI const brain death.
637 * utils.c (vprintf): Fix varargs typo.
639 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
641 * findvar.c (find_var_value): Handle &function better.
642 * TODO: Document work needed on &fn and &array.
643 * printcmd.c (print_address_symbolic): New arg is the prefix
644 to print if a name is printed.
645 (print_address_demangle): Honor "set print address" now.
646 Use new arg above to improve spacing of output.
647 * valprint.c (val_print): When printing function pointers,
648 print symbolic form too.
649 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
651 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
653 * core.c (memory_error): Reword error msg to mislead less.
655 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
657 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
658 parse_partial_symbols): Use newer BFD internals (external_filehdr
659 and external_aouthdr), byte-swap the fields that we care about
660 before using them, and make the file header data local to
661 read_the_mips_symtab rather than global.
663 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
665 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
666 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
668 * main.c (command_line_input): Flush stdout and stderr
669 before every call to readline. This reportedly fixes a bug
670 that comes up in Sys V running emacs-gdb and/or xxgdb,
671 when stdin/out are pipes or sockets.
673 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
675 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
676 Avoid declaring Makefile dependencies, because GNU Make stupidly
677 tries to update it if we do.
679 * coffread.c: Revise for minor changes to bfd internal coff
682 * configure: If -template= is given a relative path, make it
683 absolute before recurring in subdirectories.
685 * configure, configure.in, Makefile.in: Install "configure" script
686 as replacement for config.gdb.
687 * config.gdb, Makefile.dist, Makefile.sdir: Remove
688 * README: Update for configure, mostly. FIXME.
690 * Add dec3100 as equivalent to littlemips. Indicate in all host &
691 target config files that they are for the host. When the lines
692 get copied into the Makefile, this makes it more obvious what's
695 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
697 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
698 tabs, which end up in the disassembler output inadvertently.
700 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
702 Make it compile cleanly in an ANSI GCC2 environment.
704 * blockframe.c: <stdio.h>
705 * cplus-dem.c: free takes a void *, ifdef __STDC__
706 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
708 * defs.h (alloca): Avoid doing anything if alloca already def'd.
709 * stddef.h, stdlib.h: Remove these files.
710 * symtab.c: Avoid declaring qsort, close.
711 * symfile.c: Avoid declaring close.
712 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
713 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
715 Assorted other changes.
716 * dbxread.c: include "libaout.h", not "liba.out.h".
717 * printcmd.c (print_frame_args): Set recurse properly for
718 indentation of struct and array parameters.
719 * valops.c (value_cast): Allow cast to void.
720 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
721 single_step() in a target-independent fashion.
722 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
723 set up to be ready to continue. This makes us target independent.
724 * infptrace.c (child_resume): Remove call to single_step; now
725 can single step a SPARC target of any kind.
727 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
729 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
730 docn into separate sections---basically chapters, plus two loose
731 pieces that can be configured to go in different places. This
732 allows GNU m4 to preprocess the manual without coredumping.
734 * Makefile.dist: tell TeX where to find texinfo.
736 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
738 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
739 the new target "rdl-apps.texinfo" which captures the Makefile
740 variable that records where to find the Readline libraries.
742 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
744 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
745 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
746 * defs.h (const, volatile): Only define if not already defined.
747 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
749 * README: Update for release 3.95.
750 * config.gdb: Don't create readline dir in subdir builds.
751 * main.c: Include with "..." form for non-system include files,
752 so "gcc -MM" for "make depend" works.
753 Include readline files with "...h" rather than <readline/...h>.
754 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
756 * coffread.c: Undo minor damage done by Rich Pixley. Use
757 different internal and external representations of COFF
758 data structures. Use new BFD routines for swapping them in and
760 * symfile.c (free_named_symtabs): Avoid freeing file names that
761 are null or empty. Old i960 tools seem to produce files that
762 claim to have empty names, causing each successive file read
763 to blow away the previous one.
764 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
765 Move deferred_stores to top of file, but don't separate its
766 #define's from its variable. Add commentary.
767 * Makefile.dist: Fix Rich damage; undo "configure" changes in
768 favor of keeping the (working) config.gdb. Move readline
771 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
773 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
775 * infptrace.c (fetch_registers): no result, since now void.
776 * tconfig/news: target depends on m68k-tdep too.
778 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
780 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
783 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
784 applied various small fixes due to or inspired by RMS comments
786 * doc/gdb.texinfo: finished using all RMS comments, save those for
787 appendices on readline and cmd history (which are in other source
790 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
792 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
793 chapter 9; (2) documented 'break' command's menu mode for
794 overloaded names, in response to hgs problem report C++ p-31
796 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
798 * doc/gdb.texinfo: (1) better introductory example; (2) more
799 consistent use of @code, @samp, @file, @kbd throughout; small
800 cleanups to first three nodes; (3) new "Contributors" node;
801 (4) Appendix, Renamed Commands; (5) divert specialized startup
802 instructions to "Targets" chapter for generic manuals, while
803 leaving them up front for manuals specific to specialized
804 environments; (6) apply fixes from RMS comments through chapter 4.
806 * pretex.m4: modify explanatory text slightly (and redefine
807 "regexp") to keep GNU m4 from complaining. (It still crashes
808 later, but one step at a time...)
810 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
812 * readline/readline.c (update_line): Avoid dereferencing a pointer
813 before comparing it to its bounds. Saber caught this.
814 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
815 and only set PC if tgetstr returned non-null. Saber caught this.
817 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
819 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
820 stuff for config manual) here where it counts; updated
821 to use new subdir structure (gdb/doc/).
823 * Makefile: generated from above via
827 * gdbint.texinfo: added instructions on generating gdb.info* files
828 locally for release. These are ordinary info
829 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
830 Makefile)---but due to use of texinfo 2, can't count on makeinfo
831 to generate these, so we distribute them already formatted.
833 * gdb.texinfo: included full Info node and menu crud (as generated
834 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
836 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
837 put in comments-for-future gdb.info target (one day makeinfo will
840 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
842 * gdb.texinfo: Updated to include new or old undocumented
843 commands, at least the following (perhaps some others I forgot to
844 record): info f, info float, info path, info program, info s, info
845 set, info source, info terminal, info types, info user, set/show
847 Also covered all recent GDB command renames for v4.
849 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
851 * mipsread.c: Rather than keeping count of how many symtabs
852 and psymtabs we have, for sorting purposes, count them when
853 we need to sort. This fixes bug in rereading of symbol tables.
855 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
857 * infcmd.c: renamed "info path" to "show paths"
858 * gdbrc.tex: documented above.
860 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
862 * remote.c: Fix comments.
863 * utils.c (error): Force out any pending wrap output.
865 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
867 * Makefile.dist: Roll VERSION to 3.95.
868 Fix up "saber_gdb" to work again.
869 * saber.suppress: Update.
871 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
872 symtab.h, target.c, target.h: Lint.
873 * core.c: setup and select frame after reading shared libs,
874 else reading shared libs will clobber them. Lint.
875 * utils.c (error): Force out any buffered wrap text.
877 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
879 * remote.c: Remove decls of memory_insert_breakpoint
880 and memory_remove_breakpoint, no longer used. (Suggestion of
883 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
884 to make it easier to interface to "configure"'d libraries.
886 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
888 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
889 aliases for set/show print.
891 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

950 * signame.c: Cast const char* to char* when assigning to sys_siglist.
952 * utils.c (strsave): Make arg const char* not char*.
954 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use
955 bpstat_explains_signal (stop_bpstat) not stop_breakpoint.

998 can have both ints and enum type_pieces in it.
999 ({push,pop}_type_int): New functions.
1001 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

1469 (types_info): Restore this function from its untimely #if 0.
1470 It's not perfect, but it is better than nothing.
1471 (_initialize_symtab): Restore "info types".
1473 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1475 * m68k-stub.c: Remote stub for 680x0's, created from
1476 rem-m68k.shar (which is removed).
1477 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
1478 Remove RCS log stuff now that we use CVS and it blows our diffs.
1480 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1482 * symmisc.c (free_named_symtab): Make it work, in its current
1483 kludgy fashion. Change result to indicate if we blew away bkpts.
1484 * dbxread.c (end_symtab): Accumulate result from
1485 free_named_symtab and print warning if we blew user's state.
1486 * symfile.h: free_named_symtab now returns an int.
1488 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1490 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
1491 is the first symbol read, even if not mainline.
1492 (dbx_psymtab_to_symtab): symfile might be zero, cope.
1493 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1494 (set_section_command): New command ("section xxx yyy" -- should
1495 be renamed to "set section xxx yyy" FIXME) which sets the
1496 base address of a section of the exec file, overriding the
1497 virtual address that BFD reports.
1499 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1501 * exec.c: Add add_syms_addr_command to exec_ops, so you can
1502 load symbols at any address while examining an exec file.
1504 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1506 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1507 for printing the float info is host-dependent, not
1508 target-dependent. FIXME.
1509 * i386-pinsn.c: Move #includes to top, remove useless ones.
1510 * i386-tdep.c: Don't bother including <.../reg.h> since we
1511 don't use it (and it doesn't exist on host systems).
1513 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1514 Convert negative numbers properly.
1515 (ieee_test): Make numbers really random; fix format arg.
1517 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1518 * core.c (core_detach): Unpush core_ops, which might not be on
1519 top. We used to just pop the top, which broke things. Don't
1520 need dont_repeat() any more.
1521 (core_file_command): Psst! Don't repeat it.
1522 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1523 * expprint.c (print_subexp): Avoid switch fallthru on
1524 BINOP_ASSIGN_MODIFY, so we can print += and such.
1525 * frame.h: Fix typo.
1526 * inflow.c (kill_command): After killing inferior, print our
1527 current frame in the core file, if we have one.
1528 (generic_mourn_inferior): When inferior dies, either select
1529 the current frame (in the new target, e.g. core file), or
1530 set both the current and selected frames to NULL.
1532 Changes from Peter Schauer.
1534 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1536 * Make all file names fit in 14 characters (sigh and damn!):
1537 mv hp300hpux-xdep.c hp300ux-xdep.c
1538 mv symmetry-xdep.c symm-xdep.c
1539 mv symmetry-tdep.c symm-tdep.c
1540 mv convex-opcode.h convx-opcode.h
1541 mv tm-vxworks960.h tm-vx960.h
1542 mv tm-vxworks68.h tm-vx68.h
1543 mv Makefile.srcdir Makefile.sdir
1544 mv gdb-int.texinfo gdbint.texinfo
1545 mv remote-sa.m68k.shar rem-m68k.shar
1546 mv remote-multi.shar rem-multi.shar
1547 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1548 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1549 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1552 * command.c (user_info_1, user_info): New command for listing
1553 the user-defined commands.
1555 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1557 * dbxread.c (really_free_pendings): Clear file_symbols
1558 and global_symbols after freeing them; otherwise, running
1559 this function twice (if it appears twice on the cleanup
1560 chain), we try to free things twice.
1562 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1563 based on text_addr (the address of text in core), not on addr (the
1564 offset between text in the .o file and in core). This change
1565 is from Peter Schauer.
1567 * main.c: Define ALL_CLEANUPS as a cast of zero.
1568 (return_to_top_level): Use it.
1569 (main): Do all cleanups after each command run as part
1570 of the gdb startup sequence. Also do all cleanups before
1571 entering the command loop, and every time we exit the command
1572 loop and reenter. Before, the cleanups from the startup sequence
1573 were being left undone until the first error!
1574 (command_loop): Rename do_nothing cleanup to command_loop_marker
1575 so we can see it easily when examining the cleanup chain.
1576 (init_signals): Add another do_nothing for signal handling.
1577 (quit_command): Only try to kill target if it has execution.
1578 Problems in the target stack got us into a state where
1579 inferior_pid was nonzero but none of the targets had execution.
1580 In this state you couldn't exit gdb.
1582 * dbxread.c: Two changes from Peter Schauer.
1583 (echo_command): Fflush output after an echo command.
1584 (show_history): Pass all args to cmd_show_list.
1586 * utils.c (init_malloc): Call mtrace to turn on tracing
1587 if the environment variable MALLOC_TRACE is set to a file name.
1588 * mtrace.c: Add source file which provides a log of every malloc,
1589 free, and realloc to a trace file.
1590 * mtrace.awk: Add source file which analyzes the trace file.
1591 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1592 (VERSION): Roll to 3.94.3.
1594 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1595 (check_duplicates): Don't bother with watchpoints.
1596 (set_raw_breakpoint): Comment about danger of this routine.
1597 (watch_command): Parse and eval all args before calling
1600 * solib.c (find_solib): Avoid error in referencing memory to
1601 see if any more shared libraries have been added. This is
1602 particularly useful if the target has terminated. Bug reported
1605 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1606 in bringing up 3.94.2 on the Sun-3.
1608 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1609 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1610 expression (in scope) before reenabling watchpoint.
1611 * signame.c (init_sigs): Add missing declaration of i, fix
1612 sys_siglist declaration.
1613 * source.c (list_command): Fixed range computation to use
1615 * stack.c (backtrace_command): Do not allow command if target has
1616 no stack, print informative error message.
1617 * target.c (target_command): Do not write into command line
1618 because this fails if the target command is used in a user defined
1619 command. [This change was enhanced by gnu to support any-
1620 unique-prefix matching on target names.]
1621 * valops.c (value_struct_elt): Avoid infinite loop on an
1622 erroneous attempt to print the member of function (try p main.p).
1624 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1626 * expread.y (name_no_typename): Avoid reduce/reduce errors
1627 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1628 Since the GDB parser really doesn't use name_no_typename in a
1629 name-only context, the parser can't tell the diff between
1630 names and numbers here. Avoid allowing a name_no_typename
1631 to be a NAME_OR_*INT to resolve the conflict.
1633 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1635 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1637 * valprint.c (val_print_fields): bitfield printing didn't handle
1638 byte order. Indirect through a few more fns to cope.
1640 * values.c (modify_field): also cope with byte order.
1642 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1644 Cleanup for release 3.94.2:
1646 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1647 include files. Roll version to 3.94.2.
1649 * coffread.c (init_stringtab): Read length into unsigned char
1650 array before swapping; don't assume 32-bit longs.
1652 * target.c (target_info): Don't bother with get_sym_file, just use
1653 the symfile global variable.
1654 * symtab.h, symfile.c (get_sym_file): Delete it.
1656 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1657 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1658 (read_type): Replace one more error() with complain().
1660 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1662 * i960-tdep.c: Fix copyright attribution.
1664 * config.gdb: Quote all backquotes in doublequotes. You can
1665 quote me on that. BSD 4.4 shell found this one.
1667 * infptrace.c (throughout): The third argument to ptrace is an
1670 * infrun.c (wait_for_inferior): When program has terminated, we
1671 have to call target_terminal_ours before we pop that target off
1672 the stack (e.g. before a call to target_kill or
1673 target_mourn_inferior). This fixes problem where a program
1674 terminates, then GDB stops for (tty output) and you have to type
1675 "fg" to the shell to resume it. FIXME: This code for what to
1676 do after termination really should be in normal_stop instead.
1678 * gdbcore.h (read_memory_check): Change declaration; it changed
1681 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1682 4.4 prereleases, this avoids a bug in their sgtty compatability
1684 * remote.c: Use terminal.h rather than hand-rolling the same.
1686 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1687 * utils.c (strsave, strstr): Fix arg types.
1688 * valprint.c (val_print): lint
1690 MIPS symbol table support from Per Bothner:
1692 * symfile.c (symtab_fns): Remove initializer table that needs to
1693 be hacked for each new symbol file format supported.
1694 (add_symtab_fns): New function, chains symbol table
1695 handlers into the global list.
1696 (symfile_init): Search this list.
1697 * symfile.h: Add next pointer, declare add_symtab_fns.
1698 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1699 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1701 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1702 symbol *). Thus, we no longer need the hack to trash
1703 pst->filename. Good, since that hack confused code in symfile.c!
1705 (reorder_symtabs, destroy_all_symtabs): Removed static
1706 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1707 Instead, the latter now uses a temporary array (stack-allocated
1708 from an obstack, and then freed).
1710 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1711 haven't been set in the outermost stBlock of a procedure. This was
1712 a problem with f77 binaries on Ultrix 4.?.
1714 (new_symtab, new_symbol, new_type): Continue changing code to use
1715 obstacks more and otherwise conform to dbxread internal style.
1716 Made the free_code of symtabs be free_linetable (as in dbxread)
1717 instead of free_contents. This implies memory leaks when reading
1718 a new symbol table, until the conversion is finished. Did change
1719 (struct symbol) and (struct type) to be allocated on the
1720 symbol_obstack. Blocks and blockvectors are among the things
1723 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1724 tested much, but it solved one problem (reported by Meissner), and
1725 cleans up some other things. The problem happened when an
1726 included file contains actual code (functions) and not just
1727 definitions. The mips coff is a little inconvenient there, since
1728 it may cause a procedure to be mapped to the wrong psymtab.
1730 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1731 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1732 this will need work for the new core paradigm.
1734 Opcode patches from the net:
1736 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1737 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1738 missing altogether - they are added here. From Bruce Bauman.
1739 * mips-opcode.h: The low mask for C0 instructions was too small.
1740 From Garrett Lau. I modified the fix to check the entire 32-bit
1743 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1746 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1748 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1750 * dbxread.c (read_type): Pointer subtraction (value_sub in
1751 valarith.c) sometimes failed because the types of the
1752 pointers being subtracted were not identical.
1753 These differed because dbxread.c was allocating pointer types
1754 using dbx_alloc_type+smash_to_pointer_type instead of
1755 lookup_pointer_type. I failed to find a justification for the
1756 former, so I changed it to use the latter. Similarly, I
1757 replaced smash_to_function_type by lookup_function_type,
1758 and smash_to_reference_type by lookup_reference_type.
1760 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1761 _initialize_mipsread): corresponding changes.
1763 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1765 * source.c (mod_path): Do tilde_expand on each component of the path,
1766 rather than on the (list of) paths as a whole.
1767 (print_source_lines): Set first_line_listed in addition to
1768 current_source_symtab and current_source_line. If the source was
1769 not findable, after a "dir" command to fix the problem,
1770 a "list" would get the wrong lines.
1772 While I was there... (gnu):
1774 * dbxread.c (read_type): Change error to complaint.
1776 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1778 First attempt at detailed understanding of symbol table memory alloc.
1780 * dbxread.c (dbx_symfile_read): Free our string table if we
1781 aren't the mainline. Free the "info" struct since we're done with
1783 (init_psymbol_list): Free any previously allocated psymbol lists.
1784 (): FIXME: Should realloc-down the psymbol lists when done reading
1785 the main symbol file?
1787 * symmisc.c (free_symtab): Free fullname field too.
1789 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1790 (REGISTER_ADDR): Make result type unsigned int.
1792 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1793 define REGEX must also define REGEX1 (its dependency).
1795 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1797 * tconfig/i960: No longer works, points you at vxworks960 or
1800 * xgdb.c, XGDB-README: Remove file. Users can get the much
1802 * Makefile.dist: Remove all trace of xgdb.
1804 * breakpoint.c (breakpoint_1): Pass demangle arg to
1805 print_address_symbolic.
1806 (clear_breakpoints): Remove unused function.
1807 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1808 (breakpoint_re_set): Use catch_errors to do them all anyway.
1810 * gdb-int.texinfo (Host versus Target): Add section on what is
1811 a "host" feature versus what is a "target" feature.
1813 * infcmd.c (path_command, path_info): Handle the PATH variable
1814 (object search path) as conveniently as the source search path.
1815 * environ.c (set_in_environ): Set some vars in GDB's environment,
1816 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1817 * source.c (mod_path): New function, from guts of
1818 directory_command, modifies a path. Used by path_command.
1819 (directory_command): Call it.
1820 * defs.h (strsave): Declare.
1822 * utils.c (sevenbit_strings): Add new printing option.
1823 (printchar): Use it.
1824 (strsave): Provide this handy helper routine.
1825 (set_width_command): Rename set_screen_width_command.
1826 (_initialize_utils): "set screen-width" => "set width";
1827 "set screen-height" => "set height"; add sevenbit-strings.
1829 * infcmd.c (do_registers_info): Print floating point registers
1830 in raw hex as well as float format, regardless of whether it is
1831 a "virtual" convertible register.
1832 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1833 regs as a double, just in case it's being used that way.
1834 * values.c (unpack_long): Comment on array/function coercion.
1835 (unpack_double): Argument is in target byte order now. For
1836 integer arguments, just call unpack_long and float the result.
1837 * m68k-tdep.c: include defs.h for "const" handling.
1838 * remote-nindy.c: Use ieee-float stuff.
1839 (nindy_fetch_registers): Unpack double regs to host double, then
1841 (nindy_store_registers): Pack extendeds to host double, flip
1842 around by misusing unpack_double, send as target double.
1844 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1845 zero, as when stopped at the first instruction of a process.
1847 * blockframe.c: Fix filename in comment (param.h => tm.h).
1848 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1849 * tm-68k.h: Fix typos.
1851 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1853 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1855 * coredep.c (fetch_core_registers): Pass end-address of register
1856 section to register_addr as expected. Don't call supply_register
1857 if we'd just pass it garbage.
1859 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1861 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1863 * target.c (push_target, target_info): Cast enums to int for < or
1866 * stack.c (print_frame_info): Identify source file & line
1867 even if we can't print it.
1869 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1871 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1873 Clean up IEEE floating point support.
1875 * ieee-float.h: New file.
1876 * ieee-float.c: Write real routines to convert between host
1877 doubles and various target IEEE extendeds.
1878 * m68k-xdep.c: Eliminate assembler code for extended floats.
1879 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1880 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1881 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1882 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1883 double_to_ieee_extended.
1884 * i960-tdep.c: Define ext_format_i960.
1885 * m68k-tdep.c: Define ext_format_68881.
1886 * sparc-tdep.c: Define ext_format_sparc, though unused.
1887 * Makefile.dist (HFILES): Add ieee-float.h.
1888 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1891 Obsolete the "coffstrip" program in favor of using BFD's strip.
1893 * nindy-share/coffstrip.c: Remove file.
1894 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1895 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1896 * tconfig/nindy960: Remove reference to coffstrip.o.
1898 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1900 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1902 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1903 * dbxread.c: Remove static symfile_bfd.
1904 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1906 * inftarg.c (child_detach): Pop the child_ops vector if the
1907 detach is successful.
1908 * remote-nindy.c (nindy_create_inferior): Don't push a new
1909 nindy_ops since nindy uses the same one for execution and memory
1911 * core.c (core_ops): Use child_attach and child_create_inferior
1912 rather than default attach and create_inferior functions.
1914 Handle floating point registers in core files.
1916 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1917 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1918 This version untested since BFD doesn't yet support sun3 core
1920 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1921 conventions. Fix comments and style. This version has not
1922 been compiled yet, since we have no HP inhouse.
1923 * core.c (get_core_registers): Look for two sections, ".reg"
1924 and ".reg2", and pass both to fetch_core_registers sequentially.
1926 Revise directory path yet again.
1928 * source.c (forget_cached_source_info): Not static any more.
1929 (init_source_path): New default source path is "$cdir:$cwd".
1930 (dir_command): Handle variable arguments ($cdir, $cwd).
1931 (source_info): Print "Compilation directory" rather than
1932 "Originally compiled in" to remind people of $cdir.
1933 (openp): If the path contains $cwd, use current directory.
1934 (open_source_file): If compilation directory is known, replace
1935 first $cdir in path with the compilation directory.
1936 (print_source_lines): Even if we can't print the lines, set the
1937 current symtab and line for future commands like "info source" or
1938 "breakpoint". Also, error message now contains the file name,
1939 line number, and file access error message.
1940 (_initialize_source): Fix help text to describe changes.
1941 * main.c (cd_command): Forget cached source info when we chdir.
1942 * utils.c (strstr): Add simple implementation.
1944 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1946 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1947 Byte-swap COFF symbol tables if necessary when reading them in.
1948 Use complain() to replace error message in one spot. Needs
1949 corresponding change in bfd/coff-code.h to make some symbol
1950 swapping routines non-static.
1952 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1954 Merge changes from Eirik Fuller, for UTek.
1956 * defs.h (errno): Add declaration.
1957 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
1958 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1959 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1960 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
1961 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
1962 declarations of errno.
1964 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1966 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1967 <rpc/rpc.h> and <rpc/types.h>.
1969 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1971 * i960-tdep.c (examine_prologue): Add new argument limit,
1972 which stops the scan at the end of the prologue, or at the PC.
1973 This fixes a problem where it walks down into the code for the
1974 user's statements if that code looks like function prologues.
1975 Mark Fox and I have been bouncing this code back and forth, making
1976 small changes to it. Callers changed to match.
1978 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1980 Cleanup for gdb-3.94 release final:
1982 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1983 the .c files from vx-share and nindy-share, from the various
1984 macros, since they are not found via ALLDEPFILES.
1985 (SFILES): Add tm-i960.h.
1986 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1987 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1989 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1990 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
1992 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
1994 * am29k-tdep.c: Add contribution line.
1995 (examine_prologue): Cache information about function prologues in
1996 the misc-function-vector to avoid lots of references over the
1997 serial line while examining instructions.
1999 * core.c (core_close): New function made from cleanup_core.
2001 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2002 remote-vx.c, remote.c, target.c, target.h,
2003 Update target_ops vector to add attach, close, and load entries.
2004 Use add_syms_addr_command, not add_file_addr_command, for
2005 add_file. Break out close routine from existing code.
2007 * dbxread.c (really_free_pendings): Don't free pending_blocks;
2008 they are in an obstack.
2009 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
2011 (define_symbol): Add symbol type parameter; change callers;
2012 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
2013 it to influence the symbol class on the i960.
2014 (define_symbol): Swap LOC_CONST's into target byte order.
2016 * exec.c (exec_close): New function.
2017 (exec_file_command): Call it.
2019 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
2020 Fix byte order of frame pointer.
2021 (read_var_value): Result of 0 if var's value can't be found,
2022 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
2023 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
2024 (locate_var_value): Use read_var_value and use its lazy address
2025 as the location of the var's value. Lint.
2027 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
2030 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
2031 obsolete Intel versions in favor of vxgdb versions.
2032 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
2033 code dealing with byte order of values, which Intel did in host byte
2034 order rather than gdb-4's target byte order.
2035 (i960_frame_chain_valid): Move to nindy-tdep.c.
2036 (examine_prologue, skip_prologue, frame_find_saved_regs,
2037 frame_args_address, leafproc_return, saved_pc_after_call,
2038 pop_frame): Add vxgdb versions from Mark Fox.
2039 (examine_prologue, frame_struct_result_address): Add code
2040 to deal with the saved value of G13 (struct return address
2042 (frame_args_address): Modify Mark's version to prefer the
2043 saved value over the current value in the topmost frame.
2044 Cache result in the frame info to avoid performance hair in
2046 (print_fault): Add gdb960 code for printing faults.
2047 (_initialize_i960): Actually call check_host.
2049 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
2050 add stub routines. FIXME, these currently just return zero!
2052 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
2053 (attach_command): Call target_attach, not target_open, now.
2055 * infrun.c (normal_stop): Make global, not static, for vx_attach.
2056 (child_attach): Rename from child_open.
2057 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
2058 don't confuse it with a zero step_resume_break_address.
2060 * inftarg.c (child_detach): Eliminate inferior_pid test.
2061 (child_files_info): Clean up message a bit.
2062 (child_ops): Use child_attach, not child_open, to attach.
2064 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
2065 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
2066 findvar.c to here, since it depends on the contents of the
2067 shadow_contents of breakpoints, but keep if #if 0 since it is
2070 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
2073 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
2074 (ptype_command, display_command): Eliminate have_inferior_p and
2075 have_core_file_p in favor of target_has_stack or
2076 target_has_execution.
2077 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
2078 code for actually finding the values of arguments, though we still
2079 keep track of the maximum stack offset for use in printing unnamed
2080 arguments. Handle missing FRAME_ARGS_ADDRESS.
2082 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
2083 (struct nindy_regs): Define registers passed to/from nindy.
2084 (nindy_fetch_registers, nindy_store-registers): Translate between
2085 nindy and GDB formats for the registers.
2086 (dcache_init): Statically allocate the cache, since it was being
2087 allocated by a malloc that was never freed anyway.
2088 (nindy_create_inferior): Error, not core dump, if no exec file.
2089 (nindy_before_main_loop): Use target_load, not target_add_file.
2091 * remote-vx.c (net_load): Specify large timeout for load
2092 requests. Allow user to break out with INTERRUPT.
2093 (net_break): Remove useless code, clean up. Change callers.
2094 (parse-args, skip_white_space, find_white_space): Clean up arg
2095 parsing to cope with quoted strings.
2096 (net_wait, net_quit): Never call error, just return status.
2097 (vx_read_register, vx_write_register): Cleanup status checking.
2098 #ifdef the code based on which CPU we are using (960 or 68k),
2099 FIXME, this should be completely general but it isn't yet.
2100 (vx_xfer_memory, vx_resume): Cleanup status checking.
2101 (vx_run_files_info): Improve message.
2102 (vx_load_command): Renamed from vx_add_file_command. Allow load
2104 (net_ptrace): Remove unused routine.
2105 (vx_wait): Adopt code from vxgdb960 to cope with broken
2106 connections to target machine and prompt to disconnect. Remove
2107 debug printouts. Map some EVENT_'s to SIGnals.
2108 (add_symbol_stub, vx_open): Print names of object files we found,
2109 and "ok" if we read their symbols OK. Clarify output in general.
2110 (vx_attach, vx_detach, vx_kill): Add these commands.
2111 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
2112 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
2113 "info files" output, and create_inferior, since we already have
2116 * stack.c (frame_info): Replace Frame_unknown with 0.
2117 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
2118 (return_command): Pop until the PC matches as well as the FP,
2119 so it works even if the FP is shared with another function,
2120 as in "frameless" or "leaf" procedures.
2122 * symfile.c (load_command): renamed from add_file_target_command.
2123 (add_syms_addr_command): renamed from add_file_addr_command.
2124 (add_syms_command): Stub to call target_add_syms.
2125 (_initialize_symfile): Change command names and descriptions,
2126 add-file => add-syms, and load from alias to its own command.
2128 * target.c (kill_or_be_killed, maybe_kill_then_attach,
2129 maybe_kill_then_create_inferior): Default for attempts to start
2130 a process, if one is already running, is to ask about killing
2131 it and retry if yes.
2132 (upstack_create_inferior): #if-0 it, strata obsolete it.
2133 (push_target, unpush_target, pop_target): to_close() a target
2134 before unstacking it.
2135 (target_info): Renamed from target_files_info.
2136 (_initialize_targets): Rename "i files" as "i target", accessible
2139 * target.h: Improve comments about the target_ vectored routines.
2141 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
2142 Convert commenting style to standard GNU style.
2143 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
2144 (SKIP_PROLOGUE): No longer a no-op.
2145 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
2146 (*_REGNUM): Sort register numbers.
2147 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
2148 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
2149 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
2150 are now 10 byte extendeds, not 8 byte doubles.
2151 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
2152 for nindy versus vxworks targets. FIXME, this should possibly go
2153 in the target vector.
2154 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
2155 frame_saved_regs and arg pointer with each frame.
2156 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
2157 (FRAME_ARGS_ADDRESS): Use cached result.
2158 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
2159 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
2160 (PRINT_RAMDON_SIGNAL): Call print_fault.
2161 (POP_FRAME): Now works.
2163 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
2164 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
2165 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
2166 (ADDITIONAL_OPTION_HANDLER): use target_load, not
2169 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
2170 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
2172 * valarith.c (value_subscripted_rvalue): Avoid handling
2173 floats and doubles specially; it gave alignment errors. Lint.
2175 * valops.c (value_of_variable, value_of_this): Error if unknown
2178 * valprint.c (print_floating): Bcopy rather than pointer-deref,
2179 to avoid alignment problems.
2180 (value_print): Handle unknown value address.
2181 (cplus_val_print): Two args are ignored; remove them. Change caller.
2182 (val_print): Use unpack_long rather than pointer-deref.
2185 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
2186 to avoid alignment problems.
2187 (value_being_returned): Error if return value unknown.
2188 (set_return_value): Add bogosity warning, FIXME. *
2190 * TODO: A woman's work is never done.
2192 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
2193 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
2194 Add ieee-float.o to OBS.
2195 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
2196 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
2197 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
2199 Changes to generalize the VxWorks RPC protocol slightly, to handle
2200 i960 as well as 68000.
2202 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
2203 * vx-share/reg.h: Produce i960 regs #ifdef I80960
2204 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
2205 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
2206 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
2207 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
2208 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
2209 so they will move in target byte order rather than network
2210 byte order (happens to be the same).
2212 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2214 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
2216 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2219 Add contribution lines to various files, showing where they
2222 * breakpoint.c (break_insn, check_break_insn_size,
2223 read_memory_nobpt): Remove to mem-break.c.
2225 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
2228 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
2229 entry has bad register number. This change is not
2230 tested in this release, FIXME.
2232 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
2235 * value.h: Force value's contents field to be aligned to hold
2236 at least a double or a long long (if supported). This avoids
2237 doing bcopy's in and out of the contents field.
2239 (step_1): Avoid coredump under obscure circumstances when we
2242 * symtab.h (misc_info): Add field to misc function vector for
2243 any kind of cached information the target code desires. AMD
2244 29000 uses this to avoid repeating examine_function_prologue's.
2246 * coffread.c: Lint. Remove static symfile, read_section_header.
2247 core.c (have_core_file_p): Lint: remove.
2248 expprint.c (print_subexp): Lint.
2249 infptrace.c, valops.c, valprint.c: lint.
2251 Roll in changes from vxgdb-5.0.1:
2253 * symtab.h: Comment byte order of each address class. Add
2254 LOC_LOCAL_ARG for frame-relative args (960).
2255 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
2256 symtab.c, symmisc.c: ditto.
2258 * infrun.c (init_wait_for_inferior): Clear stop_signal.
2260 * remote.c (remote_resume): Error if resume with a signal.
2262 * symfile.c (prim_record_misc_function): Clear misc_info.
2263 (fill_in_vptr_fieldno): Check stub type of arg.
2265 * valops.c (value_cast): Avoid looking up names of types whose
2266 name we don't know, to prevent coredump. Sun CC produces typedef
2267 rtx and the name of *rtx is zero...
2269 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2271 Roll in changes from final AMD 29000 port (Tiemann).
2273 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
2274 for ../include/a.out.encap.h. This might not work now that BFD
2275 is separately compiled. Instead, BFD support for encap will have
2276 to translate machine type 29k into the right COFF_MAGIC.
2278 * infcmd.c: Remove references to inferior_pid that aren't used
2279 in actual ptrace calls; use target_has_execution, etc.
2280 (have_inferior_p): Remove function.
2281 (program_info): Print target info rather than "process number";
2282 avoid gratuitous messages unless from_tty.
2283 (run_stack_dummy, finish_command): Set proceed_to_finish.
2284 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
2285 main.c: Lint. Lose have_inferior_p().
2286 inferior.h (have_inferior_p): Remove, lint.
2287 (proceed_to_finish): Add flag to ask that all regs be saved
2288 by normal_stop, for the few commands that need it, speeding up
2289 serial I/O. Add comments to stop_registers.
2291 * remote-eb.c: Remove newline from breakpoint message we grep
2292 for. Never time out when running the user program.
2296 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2298 Roll in changes from vxgdb-5.0.1:
2300 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
2301 symbol in its raw form, we are processing an unlinked ".o" file.
2302 See if the target environment has assigned it an address, using
2303 target_lookup_symbol (VxWorks does), and enter it into the symtab
2306 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
2307 68k versions for a simpler version that assumes zero FP at bottom.
2308 Fixes bug of truncated stack reports.
2310 * target.h (target_lookup_symbol): Define this routine's args
2311 and result, finally.
2313 * target.c (nosymbol): Default routine for target_lookup_symbol.
2314 (target_default): Default lookup_symbol and call_function too.
2315 (files_info): Only print has_all_memory warning if a non-dummy
2318 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
2319 vx_convert_from_virtual): If target does not have floating point,
2320 zero register "values", and avoid doing cross-net conversions.
2321 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
2322 (vx_open): Rearrange code that attaches to target and reads
2323 symbols for all loaded modules, to work if some of the modules
2324 are not accessible. Add symbol_stub() and add_symbol_stub()
2325 as callbacks from catch_errors(). Allow connect attempt to be
2326 interrupted painlessly with ^C (FIXME, there are still some bugs
2327 if the interrupt happens during symbol reading.). Print
2328 final message with puts_filtered, since symbol messages are
2333 * main.c (catch_errors): Only print errstring if non-null.
2334 (command_loop): Avoid an ioctl per command to test ISATTY.
2336 * remote-vx.c (net_load): make static; avoid sophomoric msg.
2337 (vx_xfer_memory): Return correct result!
2338 (vx_files_info): Indicate whether target has float or not.
2339 (vx_lookup_symbol): Complain, not error, if target gone.
2340 (vx_open): Print "Connected" msg before disabling immediate-quit.
2341 [FIXME: lookup_symbol and vx_open changes need testing.]
2343 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
2344 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
2345 contributor lines and update copyrights to 1991.
2347 Changes from an attempted H-PUX host port:
2349 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
2350 defines PT_ATTACH and PT_DETACH but not PT_KILL.
2351 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
2352 * remote-vx.c: include <sys/time.h> for HPUX.
2353 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
2354 "core_file_command" routine to BFD regime. May not work yet.
2356 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
2358 * xgdb.c: Replace X10 version with some VJ version.
2359 (FIXME: Its copyright assignment is not on record.)
2360 * xgdb.c: Update include files to X11R4 (Xaw crud).
2361 (xgdb_display_source, create_text_widget): fix call to
2362 get_filename_and_charpos. Rewack source window stuff for X11R4
2363 (gleaned from include files, and "nm's" of binary libraries, since
2364 I had no doc available).
2365 (append_selection, append_selection_word): Disable with FIXME
2366 since R4 changed interface here.
2367 (create_buttons): Add back the old set of buttons.
2368 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
2370 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
2371 Roll VERSION to 3.94 (not yet final though).
2373 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2375 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
2376 obstack_int_grow, obstack_int_grow_fast): Eliminate
2377 cast on left of assignment, which gives MIPS cc fits and is
2380 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
2381 F_ALIAS. Use printf, not fprintf, when not passing a file
2383 (compare_opcodes): Check that identical instructions have
2384 identical opcodes, complain otherwise.
2386 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
2387 was reported by Roland McGrath.
2388 (unimp): Only match if exactly zero instruction. (Roland)
2389 (branches and traps): Generate all variations of these
2390 instructions with macros, based on a single call that defines
2391 each condition name and its binary representation.
2392 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
2394 * valprint.c (val_print_fields): Take, and use, format parameter.
2395 This means that "p/x struct" again prints the elements in the
2396 desired format. Changed callers.
2398 * stack.c (frame_info): Use filtered output, and indicate wrap
2399 points. Remove kludgy formatting designed to avoid line wrap.
2401 * utils.c (wrap_here): If the line is already full (because
2402 we had printed a long indent or long wrapped string), do an
2403 immediate newline-and-indent.
2405 * m68k-pinsn.c (print_insn_arg): Bugfix from
2406 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
2407 instruction is incorrectly disassembled as bkpt #8.
2409 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
2410 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
2411 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
2412 and then will dump core (sometimes). I traced it back to an
2413 uninitialized symfile_name in psymtab_to_symtab.
2414 (const_vol_complaint): Add quotes to message.
2415 (define_symbol): Only believe line number if gcc_compiled.
2416 Avoid allocating symbol if we will not return it.
2418 Add target strata support so that newly established targets go
2419 into their right place in the target stack (e.g. a new exec file
2420 doesn't wipe out the ability to access the running process).
2422 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2423 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2424 and initialize it properly in all the targets.
2426 * target.h: Document strata. Change return type of push_target.
2428 * target.c (nomemory): new function for dummy memory access.
2429 (tcomplain): Rename complain, now also used in symfile.c.
2430 (push_target): Push targets within strata. New return value shows
2431 whether new target is on top of stack or not. Always keep dummy
2433 (target_files_info): Ignore dummy target.
2435 * core.c (core_open): Warn user, and skip accessing file, if the
2436 core target is not the topmost target in the stack.
2437 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2440 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2441 target_ops, it doesn't belong there since we have no regs there.
2442 Change name of target from machine => memory to clarify.
2444 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2446 * Freeze version 3.93 for release.
2448 * Makefile.dist: Handle vx-share and nindy-share subdirs
2449 properly when building gdb.tar.Z.
2451 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2452 printed in various places, so I could change just one copy.
2454 * dbxread.c, coffread.c: Change references to bfd->iostream
2455 to cast to FILE *, now that BFD avoids needing types defined
2456 in other header files.
2458 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2460 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2461 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2462 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2463 (actually gcc -Wall).
2465 * dbxread.c: Remove first_global_sym, last_global_sym, since
2466 they are never referenced.
2468 * defs.h (baud_rate): Declare.
2469 main.c: Define it, and add the -b option to set it.
2471 * gdb-int.texinfo: Add text on how to define a new host or target
2472 architecture, prompted by Per Bothner's questions about MIPS
2475 * gdb.texinfo: Document "complaints". Change doc of -q since
2476 gdb no longer prints the copyright and blurb if you specify a file
2477 name to be debugged (just like Emacs). Add doc for Nindy-specific
2478 command line flags for specifying target serial port and such.
2479 Update copyright to 1991.
2481 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2482 has taken over for us the job of ripping up executable files. The
2483 crud caused Per Bothner's port to not compile.
2485 * infrun.c (normal_stop): Avoid printing "Program exited
2486 normally" if we are in batch mode. This allows a GDB which
2487 executes a program on a target system, to behave like a Unix
2488 command (input from stdin, output to stdout, no extraneous
2491 * main.c (main): Allow additional machine-dependent command line
2492 options to be specified with the ADDITIONAL_OPTIONS,
2493 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2494 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2495 processing to occur just before the main loop with
2496 BEFORE_MAIN_LOOP_HOOK.
2497 (main): If a "core file" argument is specified, and it is not a
2498 core file, try it as a process ID to attach.
2499 (symbol_completion_function): Attempt to cope with
2500 "show screen-" TAB, not very successfully. This needs more work,
2502 (batch_file): New function, returns whether we are reading
2503 commands from an interactive tty on stdin, or from somewhere else.
2504 Called by normal_stop since it doesn't get from_tty passed down
2505 to it like many commands do.
2507 * remote-nindy.c: Handle command line options for nindy
2509 (nindy_before_main_loop): Prompt user for tty name if they
2510 don't specify it before getting to the interactive command loop.
2512 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2513 and -r command line options. Also add hook before main loop
2514 to make it easy to specify a tty.
2516 * TODO: More things to do, one done.
2518 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2520 * dbxread.c: Make complaint() calls pass pointer, not struct.
2521 Add complaints about badly formatted C++ type information
2522 (const/volatile indicator, and parse errors resulting in
2523 error_type). Fix C++ virtual member fn comment.
2524 (read_struct_type): Avoid bumping pointer if we got a parse
2525 error; this prevents our walking beyond the end of a string.
2526 Terminate loop on null char as well as semicolon.
2527 (process_one_symbol): Fix the LBRAC fix so that it uses the
2528 last previous SLINE, FUN, or SO record's PC address. C++ debug
2529 symbols did not have SLINE records in a useful order compared
2530 to the LBRAC records.
2531 (define_symbol): Handle "catch" records.
2533 * symtab.c (check_stub_type): Added new complain
2534 `stub_noname_complain' and added a consistency check to
2535 keep the debugger from crashing when finishing from an
2536 exception frame. A real fix will be needed later.
2538 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2540 * infcmd.c (attach_command): Make global.
2542 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2543 but make them easy to comment out. Perhaps later they should
2544 be enabled by what CPU you configure for? FIXME.
2545 (VERSION): Roll to 3.93.
2546 (pinsn.o): Remove rule for obsolete file.
2547 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2549 Run down a problem that manifested by printing the wrong function
2550 name in stack traces of read_ofile_symtab. Turned out that the
2551 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2552 the LBRAC symbol with an address in the *data* segment, which
2553 blew our binary search through the blocks.
2555 * dbxread.c: Use the complain() facility consistently to bitch
2556 about problems in the symbol file we are reading.
2557 (finish_block): Add code to check the nesting of the blocks;
2558 complain and Procrust them to fit if wrong.
2559 (make_blockvector): Check the order of the blocks, complain
2560 [but don't cope] if wrong.
2561 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2562 symbols to be sure their PC value is greater than the last SLINE
2563 (line number) symbol we've seen, complaining and adopting the
2564 SLINE PC value if wrong.
2566 * symfile.h (struct complaint, complaint_root, complain,
2567 clear_complaints): Add.
2568 * symfile.c (complain, complaint_root, clear_complaints): Add
2569 facility to deal with non-fatal complaints and to regularize their
2571 (symbol_file_add): Clear complaint counters to allow new complaints.
2572 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2574 * dbxread.c (dbx_symfile_read): Remember the address and size
2575 of the string table for the main symbol file, so we won't read it
2577 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2578 to avoid reading the string table yet again. Lint.
2579 (throughout): Improve filtered output, including word wrap.
2580 (read_range_type): Improve Bothner's fix to handle other types too.
2582 * utils.c: Improve line wrap implementation. Handle unlimited
2583 width by making chars_per_line unsigned.
2584 (puts_filtered): New, easy, function.
2586 * defs.h (puts_filtered): add.
2588 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2589 call the identical sort_symtab_syms() in symfile.c instead.
2591 * expread.y: Suggest the `file' command rather than `symbol-file'.
2593 * command.h (enum var_types): Add zinteger for seroable
2595 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2596 nested if's into a switch.
2598 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2599 we did not stop because of a breakpoint (it must have been for
2600 some other reason, like a "stepi"), so don't print anything.
2602 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2603 doesn't include <sys/types.h>, old SunOS's require it for
2606 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2608 A test port of gdb-3.92.6 to the Sony NEWS.
2611 Don't normally link in remote- or vx stuff.
2612 Some of it doesn't compile, and it wastes space for 99% of the users.
2613 Remove reference to no-longer-used HAVE_VPRINTF.
2614 Fixed BFD_DEP typo to BFD_DIR.
2616 Fix cast in arg to bfd_h_getlong.
2617 Make char *prefix be const.
2618 Fix how certain range types are mapped into builtin unsigned int types.
2620 Remove 2 #includes. They cause errors (on Sony, at least),
2621 and aren't needed (they wern't in earlier versions).
2623 print_address_symbolic should never demangle labels
2624 (since it prints *assembler-level* labels).
2626 [This was superseded by the change to printcmd below.]
2629 Add some "volatile" return types to avoid warnings.
2630 If MISSING_VPRINTF add vprintf function and not just macro
2631 (since vprintf is used in printcmd.c).
2633 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2634 (The latter isn't grokked by some PCC-based compilers.)
2636 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2638 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2639 * nindy-share/coffstrip.c
2640 Added some forward declarations (otherwise, gcc complains
2641 about implicit extern redefined as static).
2643 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2645 Changes inspired by Per Bothner:
2646 * printcmd.c (print_address_symbolic): Take additional parameter
2647 specifying whether to demangle.
2648 (print_address): Pass in asm_demangle to control demangling.
2649 (print_address_demangle): New fn, takes explicit arg to control
2651 * utils.c: Add new vars demangle and asm_demangle, and let them
2653 (fputs_demangled): If !demangle, just print the argument.
2654 (fprint_symbol): If !demangle, just print raw symbol.
2655 * valprint.c (val_print): Call print_address_demangle rather than
2656 print_address, to cause demangling to depend on the global
2657 rather than assembler-level demangling setting.
2658 * WHATS.NEW, gdb.texinfo: Document.
2660 * main.c (show_command): Show all settings if no arg.
2661 (initialize_main): Make "info set" the same as naked "show".
2662 * command.c (cmd_show_list): Handle prefix commands in the
2663 list, and print the name of the setting as well as its English
2664 description and value.
2666 Allow gdb functions to specify where a line should wrap if it
2667 exceeds the size of a terminal line. Use it to make the output
2669 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2670 of the right size when screen width changes.
2671 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2672 (wrap_here): New fn, indicates a point in the output where we
2673 should wrap the line rather than just letting it overflow at a
2675 (fputs_filtered): Implement wrapping.
2676 (n_spaces): New fn, returns a pointer to N spaces.
2677 (print_spaces_filtered): Use n_spaces.
2678 * defs.h (n_spaces): Declare.
2679 * stack.c (print_frame_info): Wrap with 4-space indent after
2680 fn name and before filename and line number.
2681 * printcmd.c (print_frame_args): Wrap with 4-space indent
2682 before each argument name is printed.
2683 * valprint.c (value_print): Wrap with no indentation before
2685 (val_print_fields): Wrap with indentation relative to nesting
2686 level before each field name.
2687 (val_print): Wrap with nesting indentation before array elements.
2688 * command.c (do_setshow_command): Avoid extra newlines,
2689 wrap with 4-space indent around values printed, end with period.
2690 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2692 * breakpoint.c (breakpoint_1): Implement addressprint for
2693 "info breakpoints" display. Change file name and line number
2694 format to " at file:nnn" rather than " (file line nnn)".
2695 * gdb.texinfo: Document.
2698 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2700 Frozen for gdb-3.92.6 release.
2702 README, WHATS.NEW: Update for 3.92.6 release.
2704 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2705 coffread.o from configs since it is now built by default.
2706 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2707 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2708 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2709 from configs since it is now built by default.
2711 Makefile.dist: Update for release 3.92.6. Handle files that
2712 have been moved to ../include, ../getopt, or ../bfd. Add
2713 saber.suppress and tests directory. Add config.status to
2714 the release (it will say "none").
2716 coredep.c: Minor formatting fixes.
2718 These changes were made in early December but only checked in now:
2719 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2720 nindy-share/nindy.c: lint
2721 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2722 register values coming back from the target; we store values
2723 in target byte order everywhere.
2725 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2727 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2729 * valprint.c (cplus_val_print, val_print_fields): New functions,
2730 which print C++ objects. They conspire to avoid printing a
2731 virtual base class more than once, following all the twists and
2732 turns of C++ virtual base rules.
2733 (val_print): Call the above rather than do it by hand.
2735 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2736 symbol file, not for added files like shared libs. This really
2737 needs to be generalized to a timestamp per file.
2739 * core.c (cleanup_core): Avoid coredump if no core file.
2741 * config.gdb: Accept -host or -target in place of +host or
2744 * coffread.c (find_linenos): Avoid desupported BFD interface
2745 to line numbers. We still read them manually rather than using
2746 BFD's "generic" features.
2748 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2750 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2752 * Makefile.dist: Eliminate use of $< in explicit targets.
2754 * readline/Makefile: Use $< rather than $*.c, which does not
2755 include the VPATH in GNU Make.
2757 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2758 copies of tconfig/i960, added for global configuration
2759 compatability. All i960 versions can read both coff and b.out.
2761 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2762 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2765 * TODO: Think of more things to do.
2767 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2769 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2770 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2771 64-bit float conversion.
2773 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2774 equivalent to sun?os4 so global config works.
2776 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2778 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2780 * main.c: Only declare linesize once; declare pagesize not at
2781 all, since it is never used.
2782 (main): Clear newly allocated line before it is used.
2784 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2786 Further stabilization for the Intel 960.
2788 * Makefile.dist: Parameterize the location of the "include"
2789 and "bfd" directories, as well as "getopt". Add symfile.c.
2790 Link in both dbxread and coffread. Fix up "make depend" to
2791 rewack the locations of include, bfd, and getopt in its output.
2793 * README: Document moving include files, improve some of
2796 * coffread.c: Move common code out to symfile.c. Change
2797 symbol_file_command style interface to use new *_symfile_init
2798 and *_symfile_read interface under BFD. Use BFD internal
2799 info to locate line table, symbols, etc.
2801 * core.c (core_fetch_registers): Rename to get_core_registers
2802 to avoid confusion with fetch_core_registers.
2803 (register_addr): Move to coredep.c, which is already machine
2804 dependent. This leaves core.c pretty clean of dependencies.
2806 * coredep.c (register_addr): Accept this routine from core.c.
2808 * dbxread.c: Move common code (with coffread.c, etc) into new
2809 symfile.c. Each psymtab now contains a pointer to the
2810 format-dependent function that knows how to read it in. Make
2812 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2813 (process_one_symbol): Add code to complain about a "compiler bug
2814 we muzzle here", if we actually see it.
2816 * eval.c (evaluate_subexp): Insert missing "break" statements
2817 in code that determines whether a variable is an lvalue in
2818 memory, register, or whatever. I detected this via a compiler
2819 bug in which it *almost* mashed out the whole switch statement.
2821 * gdb-int.texinfo: Add minor sections on configuring gdb for
2822 release, and about the README file.
2824 * infcmd.c (registers_info): Fix formatting somewhat. Still
2825 not as pretty as before, but it handles byte swapping.
2827 * remote-nindy.c: If data cache routines are interrupted while
2828 waiting for the remote end, be sure that any uninitialized cache
2829 blocks are on the free list, not on the valid list!
2831 * symfile.h: Flesh out this header file with all the various
2832 routines and variables that have been merged in from dbxread.c
2833 coffread.c, and symtab.c to symfile.c.
2835 * symfile.c: New file, containing code common to dbxread.c,
2836 coffread.c, and some code from symtab.c. All generic code for
2837 reading symbol files should be in here now.
2838 (unrecord_misc_function): Remove unused function.
2840 * symtab.h: Remove file-reading things to symfile.h.
2842 * symtab.c: Remove file-reading things to symfile.c.
2844 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2845 to decode i960 fault types.
2847 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2848 target.c: Change type of the "resume" function from int to void,
2849 since its result was never used.
2851 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2853 * main.c: Replace "stupid" with "caution"; you now "set caution
2856 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2858 * infcmd.c (do_registers_info): Call val_print to deal with the
2859 byte order of the registers being printed. FIXME, this makes
2860 the formatting of the output uglier.
2862 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2863 defined, call it for signals the debugger doesn't itself use.
2864 The i960 uses this for more detailed fault information.
2866 * remote.c (remote_open): If arg is null, print help rather than
2869 * sparc-xdep.c (register_valid): Avoid declaring size, since
2870 various modules will think of various sizes depending on the
2871 architecture of their tm-file. FIXME, we need protection against
2872 actually entering one of those modules, which would clobber
2873 storage if not for the target architecture compiled into gdb.
2875 * stack.c (up_command, down_command): Always print the frame
2877 (up_silently_command, down_silently_command): New commands
2880 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2882 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2883 more parameters than it used to.
2885 * findvar.c (registers): Increase slop to 256 bytes, which should
2886 protect us against even most RISC machines with large register
2888 (locate_var_value): Move declaration inside related ifdef.
2890 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2891 throughout, to avoid throwing away buffered input from the board.
2892 (nindy_wait): Supply_register takes addr_of_value, not value.
2893 (i960_print_fault): Renamed from i80960_fault.
2894 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2895 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2897 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2898 we can set the PC in the call to proceed(). Unpush nindy_ops
2899 before pushing it on top, to avoid message to user. Eliminate
2900 commentary from Unix machines that just misleads here.
2901 (reset_command): Fix error message to suggest target command.
2903 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2905 Release 3.92.5 as frozen.
2907 Stabilize the merged release...with help from lint, Saber C,
2910 Everywhere: Add include files needed to declare return types
2911 of functions called.
2913 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2915 * breakpoint.h: Add undeclared breakpoint functions, and some
2916 functions for display handling since I couldn't think of a better
2919 * breakpoint.c (insert_breakpoints): Make code for disabling
2920 shared library bkpts more likely to work. It's used when we
2921 rerun a program and stop before the shared library has been
2923 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2924 cast from pointer, so it squeezes through catch_errors.
2925 (bpstat_stop_status): Fix logic broken some time ago. We now
2926 always create a bpstat if the stop address matches a breakpoint,
2927 even if we don't stop there -- just like the old code used to do
2928 before I got my fingers into it (sigh).
2929 (breakpoint_1): Print "ignore count" after "stop only if"
2930 condition, since that's how it actually works.
2931 (mention): Handle watchpoints as well as breakpoints.
2932 (watch_command): use set_raw_breakpoint and mention to do most
2933 of the work (and initialize all the fields!). Only pass one
2934 arg to parse_c_expression, since that's all it takes.
2936 * command.c (not_just_help_class_command): Rename arg to args
2937 since we ignore "unused argument" warnings on vars named "args".
2938 inflow.c (child_terminal_info): ditto.
2939 infptrace.c (kill_inferior): ditto
2940 main.c (catch_errors, version_info, quit_command, pwd_command,
2941 source_command, dump_me_command, editing_info,
2942 set_history_size_command, set_history, show_history,
2944 stack.c (locals_info): ditto
2945 target.c (target_files_info): ditto
2946 valprint.c (set_input_radix, set_output_radix): ditto
2948 * core.c: Remove old variables for handling core and exec file
2949 sections (data_start, data_end, stack_start, stack_end,
2950 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2951 text_end, exec_data_start, exec_data_end, text_offset,
2952 exec_data_offset, data_offset, stack_offset). They're
2953 superseded the more general build_section_table and
2955 (get_exec_file): Mention the `file' command.
2956 (read_memory_check): Rename to memory_error, and only call it
2957 in the case of an actual error.
2958 (read_memory, write_memory): call memory_error.
2959 (core_fetch_registers): Register section name is ".reg".
2961 coredep.c: Remove a bunch of crud now that all this file does
2962 is pull the registers out of a core file.
2963 (fetch_core_registers): Rewrite to actually work, I hope.
2965 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2966 Replace index() with strchr(). Remove all the pre-BFD macro
2967 definitions for accessing the symbol file.
2968 (struct dbx_symfile_info): Encapsulate the information that
2969 dbx_symfile_init needs to pass to dbx_symfile_read in this
2972 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2973 dbx_symfile_discard): Rearrange symbol file reading to divide
2974 the format-specific part from the format-independent part,
2975 leaving the format-independent part such as file name expansion
2976 and opening in symtab.c. This replaces
2977 partial_symbol_file_open and partial_symbol_file_read.
2978 Symbol_file_read, add_file, add_file_target_command,
2979 add_file_addr_command move to symtab.c. Pass an explicit
2980 "mainline" flag for when reading the main symbol table, rather
2981 than relying on the offset address to be zero or nonzero.
2983 (dbx_symfile_read): Don't allow void *'s to be printed as
2985 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2986 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2987 macro" debug version really work.
2988 (read_dbx_symtab): Remove unref'd parameter inclink.
2989 Avoid swapping N_SLINE symbols, for speed.
2990 Merge N_TEXT!N_EXT case with the other external symbol
2991 definitions' case. Add comments.
2992 (start_psymtab): Allocate the symfile name in the psymtab on
2993 the psymbol_obstack, rather than using the caller's storage.
2994 (end_psymtab): Only allocate a dependencies list if there are
2996 (psymtab_to_symtab_2): Use BFD when reopening file to read
2997 its symbols for real.
2998 (read_struct_type): Add FIXME comments where it needs work
3000 (read_huge_number): Add FIXME about overflows.
3001 (read_range_type): Add FIXME about comparing a long to 1<<32.
3003 * coffread.c: Minor changes to move things closer to the new
3004 regime with symtab.c and dbxread.c Major work is still needed
3007 * exec.c (exec_file_command): Remove old variables (see core.c
3009 (xfer_memory): If memory transfer is right at the end of a
3010 section, don't lose.
3012 * findvar.c (get_saved_register): If value is in a real
3013 register, LVAL is lval_register, not lval_memory.
3015 frame.h: Declare print_sel_frame and record_selected_frame.
3017 gdb-int.texinfo: New file, for GDB internals documentation.
3018 Very simple, unformatted doc of cleanups is there for now.
3020 gdbcore.h: Remove obsolete variables that described a.out
3021 section addresses and offsets. (See core.c above.)
3022 Declare fetch_core_registers and registers_fetched.
3024 getopt.c: Declare char *alloca(); even on SPARC.
3026 infcmd.c (run_command): Call target_kill rather than
3028 (step_command, next_command, stepi_command, nexti_command):
3029 Declare from_tty parameter even though we don't use it.
3030 (run_stack_dummy): argument BUFFER is a char array, not
3031 a pointer to REGISTER_TYPE.
3032 (finish_command): using_struct_return needed a value *,
3033 not a struct symbol *.
3035 * infptrace.c (child_xfer_memory): To avoid dependency on
3036 where sections are in memory, try PT_WRITE_D and if that fails,
3037 try PT_WRITE_I. Most Unixes don't care which you use.
3039 * infrun.c (step_resume_break_shadow): Change to array to
3040 match other breakpoint shadow storage.
3041 (clear_proceed_status): Pass address of bpstat to
3042 bpstat_clear, not the bpstat itself.
3043 (child_create_inferior): FIXME comment about if the child
3045 (start_inferior): Remove old function.
3046 (child_open): Use target_kill rather than kill_inferior.
3047 (wait_for_inferior): Ditto.
3048 (insert_step_breakpoint, remote_step_breakpoint): Use
3049 new step_resume_break_shadow.
3051 * inftarg.c (child_wait): If all child processes die,
3052 pretend that the one being waited for exited with signal 42.
3054 * main.c (command_line_input): When scanning for comments,
3055 don't coredump on unclosed quotes.
3056 (quit_command): Use target_kill rther than kill_inferior.
3057 (_initialize_main): Rename class_user from "user" to
3060 * printcmd.c (print_command_1): Initialize "fmt" if no format
3061 is specified by the user.
3062 (print_frame_args): Only add to args_printed if we are
3063 actually fetching args from the stack (avoiding undefined
3065 (_initialize_printcmd): Remove bogus \{ from string.
3067 * remote-eb.c (eb_open): Avoid coredump on no argument.
3069 * remote-nindy.c: Bring out of Intel environment into new
3070 target environment. Remove all conditional compilation on
3071 I80960. Massive hacking throughout.
3072 (nindy_xfer_inferior_memory): New routine stolen from
3074 (nindy_create_inferior): New routine pieced together, probably
3075 not quite working yet.
3076 (nindy_ops): New target_ops struct for nindy.
3078 * remote-vx.c: Use write_memory rather than target_write_memory
3079 to get error checking.
3080 (vx_add_file_command, vx_open): Use symbol_file_add rather than
3082 (vx_create_inferior): Use target_terminal_ours...
3084 * signame.c (_initialize_signame): Always initialize, since
3085 we need the table for things other than psignal.
3087 * solib.c (solib_add): Use symbol_file_add, not add_file.
3088 (solib_address): Return boolean result rather than struct
3089 pointer which nobody else knows the type of.
3091 * sparc-tdep.c, valops.c: Use write_memory rather than
3092 target_write_memory, to get error checking.
3094 * stack.c (locals_info, catch_info, args_info,
3095 get_selected_block, frame_command, up_command): Use
3096 target_has_stack, rather than have_inferior_p or
3099 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
3101 * symfile.h: New file, defining the interface between the
3102 generic and object-file-specific symbol reading code.
3104 * symtab.c: Move generic symbol-reading interface to symtab.c,
3105 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
3106 table to map BFD targets to symbol-reading modules in GDB.
3107 Change index to strchr.
3108 (lookup_struct_elt_type): Use error() rather than hand-made
3109 simulations thereof.
3110 (lookup_partial_symbol): Speedup slightly when length == 0.
3111 (symbol_file_add): New function.
3112 (symbol_file_command): Call it.
3113 (symfile_open, symfile_init): New function.
3114 (add_file_target_command, add_file_addr_command): moved from
3117 * target.c (target_command): use target_kill.
3119 * target.h (target_files_info): Don't declare, never called
3122 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
3123 files to determine stack end address.
3125 * valarith.c (value_x_binop, value_x_unop): Change error message
3126 to be more useful. Pass proper argument to value_struct_elt.
3128 * valops.c (value_assign): FIXME comment that long long
3129 bitfields will break here.
3131 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
3132 Update `make saber_gdb' to work better.
3134 * TODO: A woman's work is never done.
3136 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
3137 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
3138 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
3139 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
3140 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
3141 valops.c, valprint.c, exec.c: Lint.
3144 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
3146 Continuing Intel 960 port merge of GDB.
3148 * Makefile.dist: Merge i960 "nindy-share" files. Rename
3149 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
3150 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
3151 Wack over "make depend" so it handles files in subdirectories
3152 vx-share, nindy-share, bfd, and in the current directory.
3154 * blockframe.c (get_prev_frame_info): Remove fatal error
3155 if stack not defined.
3157 * core.c (core_open, core_detach): New functions that handle
3158 the old "core-file" command as "target core" and "detach" instead.
3159 (core_file_command): Call them.
3160 (core_xfer_memory): Use common routine xfer_memory.
3162 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
3163 dbxread now uses bfd for everything but symbol reading itself.
3164 BFD internals are used to drag out the relevant file offsets.
3165 (partial_symbol_file_open): Change args all around for BFD.
3167 * symtab.c: Rename "value" to "val" everywhere, so we can
3169 (symbol_file_command): New command, moved from dbxread.c
3170 and coffread.c. It uses BFD to read the file, then vectors
3171 based on its type, to dbx or coff symbol readers.
3172 * symtab.h: Extern a few vars for symbol_file_command.
3174 * target.h: Breakpoint takes a char * save area, not a char **.
3176 * valprint.c (val_print): When unpacking bitfields, offset
3177 the address in gdb of the value, if it is declared with a shorter
3178 type. Remove the last "runtime kludge test" of host byte order.
3180 * utils.c: Remove old my_bfd_read routine.
3182 * stack.c (frame_info): Use target_has_stack. Print program counter
3183 register's actual name rather than "pc", since it's called the
3184 "ip" (instruction pointer) on the i960 (sigh).
3186 * target.c (target_command): Add command for selecting a target
3187 type and calling its open routine. This is used for initiating
3188 communication with a particular target, in a generic way.
3190 * tm-i960.h: Update for modern gdb. Remove semicolons from
3191 various macros. Handle reading struct return convention, and
3192 error-out attempts to return structs with the "return" command.
3193 Be sure gdb doesn't think we know how to call functions in the
3196 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
3197 to i960_xxx in lower case.
3198 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
3199 not being defined yet.
3201 * remote.c (remote_open): Call start_remote to initialize
3202 wait_for_inferior during open.
3203 (remote_xfer_inferior_memory): Return length written rather
3206 * remote-vx.c (target_command -> vx_open): Use new generic
3208 * remote-eb.c, inftarg.c, exec.c: ditto.
3210 * infrun.c: Fix comments.
3211 (attach_program -> child_open): Use new generic target command.
3212 (wait_for_inferior): Clear saved register values before target_wait,
3213 so target_wait can set some of them if convenient.
3215 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
3216 Return success indicator, not void.
3217 (child_xfer_memory): Avoid fetching initial word if we'll
3218 overwrite it anyway.
3220 * infcmd.c (attach_command): Use new generic target open routine.
3221 (_initialize_infcmd): Update doc on attach and detach commands.
3222 (do_registers_info): Merge in a byte-order problem as a FIXME
3225 * findvar.c (find_saved_register): Avoid problem in current frame.
3226 (read_relative_register): Ditto.
3227 (write_register): Convert byte order on the way out.
3229 * exec.c (file_command): Add.
3230 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
3231 (xfer_memory): Common function between core_xfer_memory and
3233 (exec_xfer_memory): Use it.
3235 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
3237 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
3238 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
3239 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
3241 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
3243 Merge Intel 960 port of gdb, continuing...
3245 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
3246 symbol_file_command): Pass from_tty arg to hush 'em up.
3248 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
3249 Add magic numbers for 960 COFF format.
3251 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
3253 Merge Intel 960 port of gdb, from Intel "1.2" release.
3255 CHANGE_LOG entries from their port, which was based on
3258 Thu Sep 6 11:02:22 PDT 1990
3259 Remove temp file if download is interrupted.
3261 Wed Aug 1 09:08:33 PDT 1990
3262 Now uses binary protocol to talk to NINDY.
3263 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
3264 Times out after 5 seconds when trying to talk to NINDY.
3266 Tue May 29 12:54:49 PDT 1990
3267 Added variable baud rate (-b switch).
3268 Source code reorganization.
3270 Thu Apr 26 11:09:55 PDT 1990
3271 More cleanup of batch mode; specifically, execute "-s", "-e", and
3272 "-se" switches as soon as they are encountered on the invocation line.
3274 Fri Apr 20 13:47:15 PDT 1990
3277 Thu Apr 19 09:54:28 PDT 1990
3278 Add 'reset' command.
3280 Wed Apr 18 09:48:07 PDT 1990
3281 After opening remote tty, wait for 1 second to go by without input
3282 from it before trying to talk to NINDY (fixes problems with the
3283 Heurikon HK80/V960E).
3285 Mon Apr 4 16:33:05 PDT 1990
3286 Some output was not being suppressed in 'batch' mode.
3288 Thu Mar 22 15:31:11 PST 1990
3289 Ask user if old symbol table should be deleted when new file is
3292 Allow user to run a program downloaded before gdb960 was brought up.
3294 Correct "exec-file" help message for i80960 context.
3296 Correct bug in calculating user space address: could occasionally
3297 corrupt user program.
3299 Make sure to zero low-order bits in rip's because of bug in 960CA
3300 A-step part: could cause operation faults when "next"ing across
3303 Correct bug that made it impossible to get source line numbers for
3304 code loaded at addresses higher than 0x7fffffff.
3306 Wed Jan 10 12:43:22 PST 1990
3307 Open remote tty for exclusive use.
3309 Fri Jan 5 12:14:42 PST 1990
3310 Correct disassembly (CA manual was right after all):
3311 opcode for sysctl is 0x659
3313 Mon Oct 23 12:03:04 PDT 1989
3314 Use G960BASE and G960BIN environment variables to find 'sx' utility.
3316 Mon Oct 16 14:15:09 PDT 1989
3317 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
3319 Mon Oct 2 15:56:31 PDT 1989
3321 Added 960CA disassembly support.
3323 To simplify maintenance:
3324 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
3326 - eliminated opcode.h: incorporates tables into i960-pinsn.c
3327 - moved 960-specific routines from i960-pinsn.c to i960-md.c
3328 - made disassembly interface identical to that in gdmp960.
3332 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
3334 * target.h: Allow targets to stack. Add target_has_memory,
3335 _registers, etc. Restructure memory access and "info files"
3336 to walk the target stack.
3337 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
3338 target.c: Change tables to match target.h.

3343 * remote-eb.c: New memory regime, new info files.
3344 * remote-vx.c: New memory regime, new info files. Now use
3345 separate targets for VxWorks attachment to machine, and
3346 actually running a process under VxWorks, since one has
3347 stack & execution & regs and the other doesn't.
3348 * remote.c: New memory regime, new info files.
3349 * sparc-xdep.c (fetch_core-registers): New memory regime.
3350 * target.c: New routines and support for stacked targets,
3351 new memory regime, new info files regime.
3354 Generalize section handling for an arbitrary number of sections,
3355 including use of the new BFD (binary file) library.
3356 * gdbcore.h: Add struct section_table.
3357 * exec.c (build_section_table): Iterate all sections and
3358 record what gdb needs to know about them.

3365 * dbxread.c: Quick changes to make it compile with new BFD.
3366 * utils.c (error): Avoid using bfd_error in generic routines.
3368 * core.c (core_fetch_registers): Get from the ".regs" section of
3370 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
3372 * inferior.h (attach_flag): Export.
3373 * infcmd.c (run_command): use new target_create_inferior.
3374 * infrun.c (child_create_inferior): Don't return result.

3380 since been deleted, such as temporary breakpoints.
3381 infcmd.c (program_info): ditto.
3383 * core.c (core_file_command): Display the frame where the core
3388 * remote-vx.c (target_command): Merge in target command from
3389 targ-vx.c. A few other cleanups.
3391 * TODO, Projects: Lots more stuff to do...
3393 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
3395 Massive changes to wall off the remote-debugging interface
3396 behind a function vector. The port to handle VxWorks targets
3397 is also part of this.
3399 All files: Replace references to renamed functions,
3400 remove references to remote_debugging, remove references to
3401 have_include_file, have_core_file in favor of target_has_stack,
3402 target_has_memory, etc.
3404 * Modularize the breakpoint interface.
3405 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
3406 a breakpoint instruction.
3407 breakpoint.c: struct breakpoint's shadow_contents now sized as
3409 (insert_breakpoints): Vector to target to install breakpoints.
3410 (remove_breakpoints): Vector to target here too.
3411 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
3412 sparc-tdep.c (single_step): Use new breakpoint interface for
3413 the single-step breakpoints.
3414 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
3415 New file, contains routines to insert and remove breakpoints by
3416 reading out the old contents and later replacing them. This is
3417 how ptrace breakpoints work, and many remote systems as well.
3419 * tm-vxworks68.h: New config file, overrides a few things for
3420 Wind River's preferences.
3422 * target.h: New file, for transfer vector used to talk to the
3423 inferior (child, attached, core, exec, remote, etc). All accesses
3424 to the thing being debugged should come through these vectors.
3425 target.c: New file, routines to handle transfer vector.
3426 (various files): Add transfer vectors XXX_ops for the various
3427 targets and pseudo-targets (core files, etc) we support.
3429 * breakpoint.c (bpstat_stop_status): Further explorations of
3430 watchpoints and why things don't work all the time.
3431 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3433 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3434 the local gdbinit if it doesn't already have it.
3436 * core.c (core_ops): add and install.
3437 Allow core debugging without exec file.
3439 * dbxread.c (free_and_init_header_files): Merge two fns.
3440 (end_symtab): Free named symbol table when a new version comes in.
3441 (read_dbx_symtab): Relocate all kinds of symbols with base
3442 address. First step toward handling different text, data, bss
3444 (add_file_addr_command): Renamed add_file_command.
3445 (add_file_command): Vector to remote handler.
3446 Add "load" as an alias for "add-file" command.
3448 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3449 non-returning functions.
3451 * exec.c: Add exec_ops, and push it as a target when an exec
3454 * infcmd.c (run_command): Pass executable file name and arg list
3455 separately when starting an inferior. Permit "run" when no exec
3456 file is specified, for VxWorks.
3457 (detach_command): Move to child_detach in inftarg.c.
3459 * inftarg.c: New file. Unix-child-specific routines, and the
3460 child_ops structure.
3462 * inferior.h (registers): Export "registers" as the way for
3463 target dependent register handlers to find gdb's local copy of
3464 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3465 since it is now used by places that want wait_for_inferior to
3466 handle the grunge but want to see every trap from the inferior.
3468 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3469 Eliminate remote_debugging hooks in terminal handling.
3471 * infrun.c: Replace start_inferior with child_create_inferior.
3472 Move all the hair of Unix shells and ptrace idiosyncracies into
3473 child_create_inferior, so remote handlers don't have to deal.
3474 Remove running_in_shell. Rename stop_after_attach to
3475 stop_soon_quietly, and use it in a few other places where we want
3476 to just call wait_for_inferior and get control back on the first
3477 trap. trap_expected now never takes a value > 1.
3478 (init_wait_for_inferior): Initialize static vars when a new
3481 main.c (gdbinit): Add new hook for .gdbinit file name, let
3482 it be overridden by config files as GDBINIT_FILENAME.
3483 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3484 Both of these are used for VxWorks gdb.
3486 mcheck.c: rename include file "gmalloc.c" to avoid problems
3487 with system include file "malloc.c".
3489 param-no-tm.h: New include file, same as param.h but does not
3490 include the default "tm.h" file. This is used in files where
3491 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3493 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3495 remote-vx.c: New file, VxWorks remote debugging support. Uses
3496 RPC routines that are shared with the target system, in directory
3499 remote.c: Vectorize remote interface.
3501 source.c: Globalize source_path, and make an alias "l" for "list"
3502 since we now have the "load" command.
3504 sparc-xdep.c: Use new param-no-tm.h.
3506 symmisc.c (free_named_symtab): Add new function from Wind River.
3507 However, ifdef it out for now while we think about what it should
3510 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3512 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3513 non-Unix-children handle this with their own code in the target
3516 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3517 source and target lists. Add vx-share to default list of include
3518 directories. Add new files to src and target lists: mem-break,
3519 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3520 ${srcdir} versions of munch and createtags are used.
3522 * valops.c (find_function_addr): Split out of call_function.
3523 (call_function_by_hand): Rename call_function; this function
3524 calls functions in the target by laboriously patching the target
3525 word-by-word with the right stack, args, regs, etc.
3528 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3530 Handle AMD 29000 a bit better.
3532 * remote-eb.c (readchar): Mask received char log to make it readable.
3533 (remote_start): Pass arguments down to executing program.
3534 Make startaddr unsigned.
3535 infrun.c (start_inferior): Accept args, pass them to
3537 infcmd.c (run_command): Pass args down to start_inferior.
3539 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3540 the target object file format.
3541 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3543 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3544 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3546 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3548 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3549 * TODO: We did a few things, we have more to do though.
3551 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3552 * inflow.c (inferior_died): Clear deferred stores.
3554 * Debug problems with dummy frames and calls to the inferior.
3555 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
3556 * sparc-tdep.c (do_restore_insn): Simplify.
3557 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3558 (sparc_push_dummy_frame): Simplify and fix what we push.
3559 (sparc_pop_frame): Slightly more hair here, deciding whether
3560 we are restoring a saved PC or returning to a return address in %i7.
3561 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3563 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3564 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3565 * obstack.h (chunkfun): ditto.
3566 * defs.h (xmalloc, xrealloc): ditto
3568 * utils.c (quit): Grab the terminal from the child if necessary.
3570 * inflow.c (term_status_command): Rename to term_info, change
3573 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3574 (is_delayed_branch): Speed up.
3575 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3576 Still missing some float ops, and needs testing.
3578 * Support for input and output radixes other than base 10
3579 * defs.h (input_radix, output_radix): Declare.
3580 * expread.y (yyparse, parse_number): Handle changes of input
3581 radix, and ambiguous names-or-numbers in radixes >10.
3582 * printcmd.c (print_scalar_formatted): Print formatted hex
3583 numbers in varying column widths.
3584 * valprint.c (val_print): Use output_format to print scalar ints.
3585 (set_input_radix, set_output_radix, set_radix): Create.
3586 (set_output_radix): Set output_format from output_radix.
3587 (_initialize_valprint): add `set radix' but leave the others off.
3589 * main.c (execute_command): Let stupid questions be turned off.
3590 (_initialize_main): Handle "set stupidity", etc.
3592 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3593 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3595 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3597 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3598 bfd stuff is still screwed up, but with some manual work, it
3601 * breakpoint.c (bpstat_do_actions): Start over if a command
3602 proceeds the inferior, since the inferior will have stopped and
3603 will need to have its new stop-actions taken care of.
3605 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3606 compiler fits, simplify it.
3608 * gdb.texinfo (directory command): Doc new dir command.
3609 source.c (directory_command): "dir" now puts things on the front
3610 of the path, moves dups up front, and handles multiple names
3611 on the command line, inserting each one in order. It also
3612 blows away cached line and full_filename info.
3614 * stack.c (backtrace_command): Skip "more stack frames follow"
3617 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3618 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3619 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3620 The only odd one was Gould NP1, which had defined vprintf to
3623 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3624 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3625 variable, inspect_it.
3626 valprint.c (print_string, val_print): Use the global inspect_it
3627 to indicate whether to print in Epoch style or normal style.
3629 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3631 * printcmd.c (call_command): add an alias for the "print" command
3632 which runs expressions and doesn't print the result if void.
3633 (print_command_1): implement it.
3635 * command.c: Remove #if 0'd code. Initialize all the fields
3636 in add_cmd (). Rename do_nothing_command to
3637 not_just_help_class_command, and make it externally visible.
3638 command.h: add user_commands to struct.
3639 * main.c (define_command): Don't overload c->function with a char
3640 string as well as a function pointer.
3642 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3643 calling convention of value_struct_elt () that got dropped in
3646 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3647 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3649 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3651 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3652 until a good time (e.g. when we are about to run the child),
3653 saving ptrace calls.
3654 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3655 * tm-sparc.h: define DO_DEFERRED_STORES.
3657 * sparc-xdep.c (store_inferior_registers): when storing float
3658 registers, don't store stack regs too. When storing the SP,
3659 however, DO store the stack regs too. This fixes a bug in which
3660 the dummy frame is not recognized when a call_function finishes,
3661 because its frame pointer (in the stack regs) was never
3663 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3664 even though we don't know how to read them from an inferior.
3665 valops.c (call_function): Comment about storing SP.
3667 * infrun.c (save_inferior_status): Save away the original bpstat
3668 chain so it can be restored later. Install the copied version for
3669 use by whoever saved the status. It will be blow away by
3670 restore_inferior_status, and the original chain restored. This is
3671 important for people who have pointers into the original.
3673 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3674 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3675 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3678 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3680 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3681 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3682 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3684 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3686 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3687 Store the baseclasses in a type struct starting from array element
3688 0 rather than from the unusual array element 1.
3690 dbxread.c: the above.
3691 (virtual_context): Add
3692 Read new debug information about which virtual function table
3693 a virtual function is from, and store it in fn_field.fcontext.
3695 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3696 TYPE_FN_FIELD_STATIC_P.
3698 symtab.c: the above.
3699 valops.c: the above. Handle pointer casts of object *'s.
3700 (search_struct_method): Add.
3701 (value_struct_elt): First arg is now a pointer to a value, and is
3704 valprint.c: the above.
3705 values.c (value_virtual_fn_field): Add type arg. Handle
3706 offsetting to the proper object when calling virtual fns.
3708 (baseclass_addr): Add valuep arg.
3710 * README: Document the current state of BFD config (missing).
3711 * TODO, ChangeLog, Makefile.dist: Roll version.
3712 * WHATS.NEW: Add summary of changes since 3.5.
3714 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3716 * dbxread.c (read_struct_type): Clear bit vectors whenever
3718 symtab.c (B_CLRALL): define.
3720 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3721 using == rather than =. Huh... This fixes the dreaded problem
3722 wherein builtin_type_int becomes TYPE_CODE_FLT.
3724 * core.c (info_files): Show the inferior pid.
3726 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3727 already knows how to look in the source directory.
3729 * Remove psymtab hair from many places. Remove duplicated code
3730 for searching symbol tables. Hide psymtabs from most places.
3731 Make it fast to get from a psymtab to its symtab.
3733 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3734 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3735 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3736 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3737 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3738 new symtab completely. New psymtabs get symtab pointer
3739 initialized to zero. Remove MI warning printf.
3740 symtab.h: Comments. Add psymtab to symtab pointer.
3741 (PSYMTAB_TO_SYMTAB): New macro.
3742 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3743 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3745 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3747 (print_frame_info): Avoid special-casing symbols that have not yet
3750 * source.c (open_source_file): Quick path if we have already
3751 located the source file by its full name.
3753 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3754 find_pc_psymtab. When a name is found in the misc function
3755 vector, search the symbol table for its mangled name, not the
3756 name that the user typed.
3758 * bfd.h: Fix missing comment terminators, make #endifs match.
3760 * valarith.c (value_less): Handle unsigned int comparisons.
3761 Add FIXME about pointer compares, which assume host and target
3762 pointers are the same.
3764 * command.c (do_nothing_command): lint
3765 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3766 fix comments on debug symbol format for visibility. Actually set
3767 visibility of symbols.
3768 main.c (echo_command): lint; use <readline/history.h>.
3769 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3770 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3771 pointing past end of allocated memory; saber complains.
3772 obstack.h: Declare the external functions that we use.
3773 valarith.h: use <string.h>
3774 solib.c (solib_add): lint.
3776 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3778 * main.c (initialize_main): Default info_verbose to off, now that
3779 symbol reading is fast.
3780 (quit_command): Avoid clobbering exec_bfd while quitting.
3782 * Initial BFD (binary file diddling library) merger:
3783 coffread.c: Change AOUTHDR to struct exe_hdr.
3785 core.c: initialize initialized data at compile time.
3786 (core_file_command): Move from coredep.c, convert to bfd.
3787 (xfer_core_file): Convert to bfd.
3788 exec.c (exec_file_command): use bfd routines.
3790 mips-tdep.c: Remove exec_file_command and friends.
3793 * coredep.c: (fetch_core_registers) Convert core_file_command to
3794 fetch_core_registers.
3795 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3797 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3798 (my_bfd_read): More bogosity, which I don't think we call.
3799 (program_name): Remove this atrocity asap!
3801 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3804 values.c: allocate_repeat_value was not clearing the
3805 optimized_out field.
3806 (value_static_field): minor stylistic fix (wrong macro was used).
3807 valops.c (value_struct_elt_for_address): didn't work for C++
3810 * signame.c (_initialize_signame): Initialize signal names once.
3812 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3813 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3814 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3816 * remote-eb.c: Support user-settable baud rates on the serial port.
3818 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3820 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3822 * tconfig/sun3os4: Remove warning about native assembler,
3823 since it also occurs in the xconfig file.
3825 * findvar.c (registers): Allocate some slop after `registers'
3826 to prevent stray accesses from trashing the next variable.
3828 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3829 on the sun-3, by changing the #ifdef from `sun3' (which is not
3830 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3831 vars, which happened to follow `registers' in the executable.
3833 * readline/history.c (history_search): Heed gcc-2's advice
3834 and parenthesize && inside ||).
3836 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3837 tm-29k.c: Insert FSF copyright headers.
3839 * remote-eb.c: Better comments.
3841 * Makefile.dist: Update to 3.91.6.
3842 * TODO: note PREPARE_TO_STORE problem.
3844 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3846 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3848 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3850 * infrun.c (wait_for_inferior, at end): Don't set up
3851 prev_* if the inferior no longer exists.
3853 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3854 CANNOT_EXECUTE_STACK.
3855 valops.c (call_function): Use it.
3857 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3859 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3860 infrun.c (wait_for_inferior, 2 places): Use it.
3862 * values.c (value_being_returned): Only use
3863 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3865 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3866 right thing for remote-eb.c.
3868 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3869 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3871 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3872 (FRAME_FIND_SAVED_REGS).
3874 * findvar.c ({fetch,store}_registers): Check for
3875 REMOTE_{FETCH_STORE}_REGISTER macro.
3877 * findvar.c (get_saved_register): Add argument lval and
3878 change meaning of argument addr.
3879 findvar.c: Change calls to get_saved_register to reflect
3880 new calling convention.
3881 valops.c (value_assign): Use get_saved_register instead of
3882 find_saved_register.
3884 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3886 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3887 an (uninitialized) pointer to one. Use "&" when passing it
3890 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3892 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3895 * coffread.c (symbol_file_command): Put semicolon after
3897 Put safe_to_init_tdesc_context in #if defined (TDESC).
3898 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3899 coffread.c: #include <sys/stat.h>.
3900 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3901 Add missing ')' in check for "lc%" and friends. Remove
3903 Declare read_one_sym() at top of file.
3904 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3905 MC68WRMAGIC can have the same value without causing a duplicate
3908 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3910 * Allow a Makefile to be built without building the
3911 tm and xm file links that screw up builds in subdirectories.
3912 This is done with `config.gdb none', then you can do things
3913 like `make gdb.tar.Z'.
3914 * tconfig/none: Config file for no target system
3915 * xconfig/none: Config file for no host system
3916 * config.gdb: If no TM or XM files are called out by the
3917 host or target file, don't make links for them.
3919 * cplus-dem.c: Add documentation.
3921 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3922 simple error, so the user's gdb doesn't crash due to some object
3923 file problem (e.g. somebody is rebuilding the file out from under
3926 * printcmd.c (print_address_symbolic): demangle the symbol.
3928 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3929 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3930 (alldeps.mak): sort and uniq all results from this; duplicates
3931 hose gdb.tar.Z link building. Remove RCS files from
3932 tconfig and xconfig. Add config files for sun386. Add
3933 a few odd files to OTHERS and HFILES.
3935 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3937 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3938 Roll version number to 3.91.5. Make lint work in bindir.
3940 * README: Document cross-debugging and new file structure.
3942 * blockframe.c: Lint. Include "value.h" to declare read_register.
3943 (find_pc_partial_function): remove duplicate line.
3945 * command.h: Lint. Declare error_no_arg and dont_repeat.
3947 * tm-news.h: Remove inadvertently duplicated stuff.
3949 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3950 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3952 * config.gdb: Allow `config.gdb host target' form. Clean
3953 up previous change that printed bogus messages when you just said
3956 * core.c: #include "command.h" for lint.
3959 * main.c: Remove some casts of enums. Lint.
3966 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3968 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3969 read it from memory. This will allow us to save ptrace calls
3970 eventually. Changed caller single_step too.
3972 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3973 that we aren't going to use, saving many ptrace calls, especially
3974 when watchpointing or single stepping. Use some #define's for
3976 (store_inferior_registers): Ditto.
3977 (core_file_command): Use some #define's for constants.
3979 * tm-sparc.h: Add #define's for some register numbers, so we
3980 can eliminate the use of random constants in sparc-xdep.c.
3982 * stack.c (frame_command, print_frame_info, up_command,
3983 down_command) Remove frame_changed, since it
3984 causes a bug and doesn't seem to do anything useful. In some
3985 places it was used as a flag, in others as a stack level (?).
3987 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3988 default is to use the portable (vprintf) version rather than the
3990 * xm-news.h (MISSING_VPRINTF): Add.
3992 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3994 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3996 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3997 about linking debugged programs -Bstatic in the sun?os4 config
3998 files in tconfig and xconfig subdirectories.
4000 * main.c (main): Remove unreached exit(0) now that we exit
4003 * Create TODO file for online bug list. There are too many
4004 "little" bugs to keep track of on paper.
4006 * Change Projects file to refer to bug-gdb@cygnus.com
4007 rather than kingdon@ai.
4009 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
4011 * Makefile.dist (VERSION): 3.91.4 now.
4013 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
4014 (condense_misc_bunches): Add sanity check that misc_count is
4015 the same as the number of symbols in the bunch.
4017 * coffread.c: rename init_misc_bunches. Pass an argument
4018 to condense_misc_bunches (a zero).
4020 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
4021 every time we are called; don't rely on our caller to do it.
4022 (add_file): Remove call to init_misc_bunches.
4024 * mipsread.c: Only warn, don't error, if unknown symbol types.
4025 This keeps an old gdb from falling on its face if it sees newly
4026 extended symbol info. Rename init_misc_bunches.
4028 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
4030 * Merge in changes from Per Bothner for DECstations and other
4031 MIPS stuff. The rest is Bothner speaking:
4033 The next message is a merger of Alessando Forin's mips port with
4034 mine. I've tried to use my good if biased judgment to get
4035 the best of both. It *does* need testing.
4037 Some of the changes are general, *not* mips-specific.
4040 Didn't believe in little-endian bit order.
4041 There are still inconsistencies about whether flags
4042 like BITS_BIG_ENDIAN are integer (#if ...) or
4043 boolean (#ifdef ...). I tried to paper over them.
4045 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
4046 Moved some misc_function code that was common to
4047 {dbx,coff,mips}read.c to symtab.c.
4048 In the process, I think I cleaned things up a bit.
4049 At the same time, moved obsavestring and obconcat to symtab.c.
4052 Removed obsolete condense_addl_misc_bunches (use
4053 condense_misc_bunches(1) instead).
4056 Needed to include <sys/dir>, at least on DECstations.
4058 valops.c, mips-tdep.c, tm-mips.h:
4059 Added PUSH_ARGUMENTS macro to support funny argument-pushing
4060 conventions (when STACK_ALIGN is insufficient).
4061 Needed on mips, where doubles need 8-byte alignment,
4062 but ints only need 4.
4065 Removed cruft that was not being used.
4066 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
4069 Print $ before register-names (I think that makes things a little
4071 Never print two instructions, even if one delays.
4072 Removed hex-disassemble set_cmd. (This is not mips-specific,
4073 so I think the argument is whether it is generally worthwhile or not.
4074 I'm inclined to think not, given how easy it is to
4075 convert between radixes in gdb.)
4078 This is basically Alessando's code.
4079 It doesn't use obstacks; I changed it to use obstacks
4080 in a few minor places where using malloc causes a
4081 memory leak. (Probably, more places could/should be changed.)
4082 I added record_misc_function where it was missing.
4083 In symbol_file_command and add_file_command, I tried
4084 to make the code consistent with more recent versions.
4085 Minor sylistic changes in parse_procedure.
4086 Make a .gdbinfo. psuedo-symbol point back to the real
4087 procedure symbol (using the isym field).
4090 This is basically from my port, but with a lot of details
4091 and a number of routines merged in from Alessando's version.
4092 I basically used my code "raw" backtrace (use heuristics
4093 from the actual code, rather than symbol table info) - though
4094 the idea is Alessandro's. I feel my code is a little cleaner
4095 here, particularly in being a little more flexible, such as being
4096 able to handle gcc-produced code (which it now can).
4097 It also doesn't do frame caching (which is not useful
4098 more recent gdb versions).
4099 I also used my code for push_/pop_dummy, more or less.
4100 I tried to incorporate AF's code for testing sigtramp
4101 while backtracing; I probably got it wrong.
4102 Added mips_print_register, which tries to scrunch as much
4103 information as possible on a screen...
4104 Removed the skip-prologue set_cmd. As with hex-disassemble (see
4105 under mips-pinsn.c), I don't see anything mips-specific here,
4106 and I don't see it being all that useful anyway.
4109 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
4110 Use more register names (rather than hard-cases numbers).
4112 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
4114 * Hack up 3.90.11 changes:
4116 * Makefile.dist (depend): parameterize $(GCC).
4117 Add solib.c and solib.o.
4118 (readline): Fix vpath for both absolute or relative SRCDIR.
4120 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
4121 Also, let the part I didn't understand at least compile so
4122 I can test the rest. FIXME.
4124 * dbxread.c: Fix thinko using strcmp.
4125 (init_psymbol_list): declare static.
4126 (partial_symbol_file_open): Comment cleanups better, avoid
4127 cleaning up the string table since the caller will do that.
4128 Move the stat for mod time into symbol_file_command, temporarily.
4129 (There should be a mod time for each symbol file, eventually,
4130 to control its rereading. FIXME.)
4132 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
4133 SunOS, which gives error for shared libs otherwise. (From
4134 Schaefer, probably FIXME needs work for portability.)
4136 * solib.c: Move #include "param.h" to work.
4137 Lowercase all the Uppercase Letters In the Messages.
4138 (find_solib): Clean up inferior_so_name for debug printouts.
4139 Allow no argument, to mean all shared libraries.
4141 * symmisc.c: include param.h to get CLEAR_SOLIB.
4143 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
4145 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
4146 to 3.90.11. ChangeLog entries below are from this.
4148 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4152 * Makefile.dist (HFILES): Add tm-sunos.h.
4154 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4158 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
4160 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
4162 * sparc-opcode.h Added single-operand version of rett.
4164 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4166 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
4167 Put parens around gcc_p in expansion.
4169 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4171 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
4173 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4175 * Changes for Sun shared libraries:
4176 blockframe.c (find_pc_partial_function): If a non-text symbol
4177 is found, set *address = pc - FUNCTION_START_OFFSET.
4178 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
4179 Disable breakpoints instead of giving an error.
4180 source.c (select_source_symtab): Initialize cs_pst.
4181 symmisc.c: Call CLEAR_SOLIB if defined.
4182 symtab.h: Make text{low,high} CORE_ADDR not int.
4183 (psymtab): New field addr.
4185 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
4186 (record_misc_function): Give correct type for N_DATA symbols.
4187 (condense_misc_bunches): do "misc_function_count = j" regardless
4189 Take code which is shared between symbol_file_command and
4190 add_file_command and put it into partial_symbol_file_{open,read}.
4191 Split add_file_command into add_file_command and add_file.
4192 Make psymtab_to_symtab read in the string table if the file
4194 Two new parameters to read_dbx_symtab and start_psymtab.
4195 tm-sunos.h: New file.
4197 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4199 * infcmd.c: Change cont_command to continue_command and "cont"
4202 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4204 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
4206 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
4208 * values.c (USE_STRUCT_CONVENTION): Check for structures of
4209 size 1,2,4,8 rather than size < 8.
4211 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
4212 as necessary, not just once.
4214 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
4216 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4218 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
4220 * tm-news.h: Add CALL_DUMMY_*.
4222 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
4224 * config.gdb: In list_host, list_target, use ${i}, not $i.
4226 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4228 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
4230 * sparc-opcode.h: Change all store floating-point state register
4231 instructions to have the right match & lose fields.
4233 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4235 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
4237 config.gdb: If srcdir != ., create readline directory and
4238 copy a makefile into it.
4240 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
4241 consistency with POSIX.
4243 * breakpoint.c (bpstat_stop_status): Disable watchpoint
4244 when we exit its exp_valid_block.
4246 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
4248 * Makefile.dist: Bump version to 3.91.3.
4250 * Clean up handling of breakpoint commands (somewhat).
4251 Prompted by Tiemann bug report "cont 10" doesn't work any more.
4253 inferior.h: Add breakpoint_proceeded to inferior status struct
4254 and globals; save it and restore it.
4255 (clear_breakpoint_commands): Cleanup, remove old #define.
4257 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
4258 (save_inferior_status, restore_inferior_status): handle it also.
4259 (proceed): Remove earlier code that set breakpoint_proceeded.
4260 It is now set only in clear_proceed_status.
4261 (clear_proceed_status): Cleanup, use bpstat_clear rather
4262 than clear_breakpoint_commands. No callers need the stop_bpstat
4263 between clear_proceed_status and proceed.
4265 infcmd.c: Add breakpoint_proceeded definition and comment.
4266 (cont_command, jump_command, signal_command): Move call to
4267 clear_proceed_status right next to call to proceed.
4269 breakpoint.c (bpstat_do_actions): Avoid clobbering our
4270 caller's argument while running down the chain of breakpoints.
4271 Use new variable "breakpoint_proceeded" to determine when
4272 a command that it executes moves the inferior past the
4274 (bpstat_clear): Handle NULL argument.
4275 (bpstat_clear_actions): Avoid useless call to
4276 breakpoint_auto_delete.
4277 (delete_breakpoint): Clean up bpstat's that are pointing to
4278 the deleted breakpoint from the stop_bpstat chain.
4279 (breakpoint_auto_delete): Simplify.
4281 * Clean up handling of EOF, error on stdin, etc. This was
4282 prompted by a network problem that caused gdb to go into an
4283 infinite loop filling up its malloc'd memory.
4285 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
4286 not clear_breakpoints_commands, which is now gone.
4287 (main): If command_loop returns (e.g. from EOF on stdin), do
4288 a quit_command (looping back to command_loop if quit_command
4289 doesn't really quit).
4290 (command_loop): check result from command_line_input and
4291 exit if it returns NULL, rather than passing the NULL to
4293 (gdb_readline): Free malloc'd result space before returning
4296 * utils.c (query): Handle C-d to mean "yes", just as if the
4297 input was not a terminal. Also avoid infinite loop if EOF
4298 occurs in mid-input-line before newline. This allows
4299 query to be used at EOF on stdin with reasonable results.
4301 * infrun.c (proceed): Set breakpoint_proceeded.
4303 * values.c (value_as_long): Avoid infinite recursion for enums.
4304 (_initialize_values): Fix typo in help msg (kingdon).
4306 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
4307 RL_LIB for linking. This allows -lreadline for linking
4308 and nothing for dependencies, once readline is a real library.
4310 * config.gdb: Jim Kingdon: give useful error message if the
4311 host or target type is not recognized.
4313 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
4314 it just defines it. Dumb, but deal with it.
4316 * Jim Kingdon suggests:
4317 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
4319 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
4321 * Makefile.dist (VERSION): Bump version # to 3.91.2.
4323 * Clean up Bothner's changes.
4325 * blockframe.c (clear_pc_function_cache): New function.
4326 * blockframe.c: remake cache_pc_function_* static.
4327 * dbxread.c (symbol_file_command): remove references to
4328 cache_pc_function_* variables.
4329 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
4330 * printcmd.c: Avoid kludging a global variable (addressprint)
4331 to avoid printing the address of a string twice. Instead,
4332 pass the format letter 's' down low enough that it can be seen
4333 to avoid this problem.
4334 (print_formatted): Pass format arg to value_print.
4335 (restore_addressprint): Remove function.
4336 (do_examine): Avoid hacking addressprint, cleanups and such.
4337 (print_frame_args): Add a comment to a Bothner change.
4338 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
4339 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
4340 to wipe out the values cached in blockframe.c.
4341 * symtab.c (find_method): Add comment saying how big you must
4342 allocate to be "big enough". Per being terse again.
4343 * valprint.c (val_print): Handle format letter "s" to print
4344 strings without addresses. Add comment to vtbl printing code
4345 which casts with wild abandon. Rearrange reference-printing
4347 @0xaddr: value (print w/addressprint)
4348 value (print w/~addressprint)
4349 @0xaddr (parameter lists w/addressprint)
4350 or nothing (parameter lists w/o addressprint)
4352 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
4354 * Merge more changes from Per Bothner:
4356 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
4357 annoying) that I tried to improve it. Here are my suggestions.
4359 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
4362 Do automatic de-reference when taking the address of a reference.
4364 Don't deref_ref when printing parameter lists.
4366 More attempts at treating refernences properly.
4368 In val_print, if deref_ref==0, don't print dangling " = ".
4370 Add COERCE_REF macro, which de-references an REF.
4372 * Merge changes from Per Bothner:
4374 * Fixed (Sony news)-specific configuration problems.
4375 * Fixed other problems with using vanilla pcc and libc (enum problems;
4376 assumption that vsprintf exists).
4377 * Some major speed-ups (finc_pc_partial_function now caches a match;
4378 parsing avoids duplicate symbol_lookup calls).
4379 * Changed handling of baseclasses (no longer use baseclasses field
4380 of struct type, use the first n_baseclasses fields instead).
4381 * Various minor changes/fixes, most C++-related.
4384 Cache the most previous match from find_pc_partial_function.
4385 (Save both low and high ends of matching function's pc range.)
4386 This speeds up the loop of infrun.c:wait_for_inferior quite
4387 a bit, and makes step/next commands much zippier.
4389 Added an enum->int cast (otherwise, some compilers barf).
4391 No longer set baseclass offset to 0, since multiple
4392 inheritance now mostly works.
4393 Added a number of casts, to shut up compiler warnings
4394 (after stabs where made enums, not ints).
4395 When discarding a symbol table (in symbol_file_command),
4396 must clear the cache introduced in blockframe.c.
4397 Don't convert $vtbl_ptr_type to vtbl any more.
4398 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
4399 Mask off sign bit emitted by g++ for virtual table offset.
4400 Set voffset to -1 (not 1) for static member functions.
4402 Changed parsing/lexing of names to avoid doing symbol lookup twice
4403 (once when lexing to determine symbol class, once for real).
4404 Now only call symbol_lookup once. Fields of 'this' win especially big.
4406 Subpress printing addr twice in the case of 'x/s addr'.
4408 lookup_basetype_type is no longer used.
4409 Add find_methods as recursive helper function to decode_line_1.
4410 This allows multiple inheritance to work.
4411 Also, once one or more matches has been found, do not look in
4412 base-classes. (Baseclass methods would be overridden, anyway.)
4414 Removed baseclasses array in struct type.
4415 Instead of using baseclasses[i], use fields[i-1].
4416 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
4417 Changed sign convention of voffset (previous was inconsistent).
4419 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4421 Used to assume existence of vsprintf. Re-written to not need it
4422 if HAVE_VPRINTF is undefined.
4424 typecmp was too pessimistic. Made it less so.
4426 Don't print space after address.
4427 If vtable points to a misc symbol (with 0 offset), print it,
4428 since that indicates the actual class of the object.
4429 Changed ype_print_derivation_info to use new inheritance
4430 scheme (without baseclasses vector).
4432 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4433 Also, changes needed because TYPE_BASECLASSES were removed.
4435 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4437 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4440 If there is no path set, and the symbols don't indicate what directory
4441 a file was compiled in, look in the current directory. But either
4442 a path or a known compilation directory will prevent this.
4445 Three independent bug fixes:
4446 * Remove the #if 0 block that breaks some stuff.
4447 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4448 adapt gdb to either SunOS 4.0.* or 4.1.
4449 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4452 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4455 (type_print) Demangle the name being printed.
4456 (type_print_base) Handle botched demangling without coredump (tiemann).
4459 (check_stub_method): Document routine.
4460 (tiemann) fix bug for no-arg functions
4461 Avoid clobbering beyond end of malloc'd storage.
4462 Terminate the argument list properly.
4464 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4466 * Changes merged by John Gilmore:
4469 In breakpoint_1, use new print_address_symbolic instead
4470 of find_pc_partial_function. (This forces use of assembler-level
4471 addresses, and avoids misleading non-mangled source-level names.)
4473 Generalize ansi argument such that -1 means skip arglist totally.
4474 Removed global variable print_ansi_qualifiers (which made
4475 code non-reentrant), in favor of extra explicit arguments
4476 to internal routines.
4478 Add new helper function print_address_symbolic.
4479 Use find_pc_misc_function instead of find_pc_partial_function
4480 (since we want assembler-level symbols here).
4482 Print unknown function as just "f (...)", not "f (...) (...)".
4483 Use new fputs_demangled explicitly.
4485 Fixed a typing violation (problem: value.h cannot be imported
4486 without renaming many variable in this file).
4487 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4488 decode_line_1: Moved forward some never-reached code.
4489 Made decode_line_2 skip function prologues correctly.
4491 fputs_filtered should not demangle by default.
4492 Add new fputs_demangled to demangle on demand..
4494 Change value_struct_elt to use value_primitive_field (using recursive
4495 utility function search_struct_field). This allows foo.bar to work
4496 for multiple inheritance (so far only for data fields).
4497 Change check_field in the same way (recursive helper function
4498 to support multiple inheritance).
4499 (Note: there are more of these problems that I haven't fixed.
4500 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4501 value_of_this: 'this' symbol name is now just "this", note "$this".
4503 Don't print static members.
4504 Avoid printing "members of <type>" if there are none.
4505 Simplified type_print_derivation_info by merging duplicate code.
4506 Remove useless blank lines in type_print_base (ptype command).
4508 Added declaration of new routine value_primitive_field.
4510 Added value_primitive_field which is generalized version of
4511 value_field that can handle multiple inheritance (non-zero offsets etc).
4512 Re-implemented value_field to call value_primitive_field.

4516 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4517 delete the whole environment. Karl Berry reported the bug.
4518 * source.c - fix openp to avoid //'s in filenames, which
4519 trigger an Emacs bug causing it to not be able to find files
4520 when running gdb in a window.
4521 * dbxread.c - zap the #if 0 that botches the add-file code.
4522 It seems to work a lot better without all the code commented out.

4545 format controls easier
4546 * wait.h added a couple of undef's because we were getting
4547 complaints about WSTOPSIG and WTERMSIG begin redefined.
