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

944 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
946 * signame.c: Cast const char* to char* when assigning to sys_siglist.
948 * utils.c (strsave): Make arg const char* not char*.
950 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use
951 bpstat_explains_signal (stop_bpstat) not stop_breakpoint.

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

1469 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1471 * m68k-stub.c: Remote stub for 680x0's, created from
1472 rem-m68k.shar (which is removed).
1473 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
1474 Remove RCS log stuff now that we use CVS and it blows our diffs.
1476 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1478 * symmisc.c (free_named_symtab): Make it work, in its current
1479 kludgy fashion. Change result to indicate if we blew away bkpts.
1480 * dbxread.c (end_symtab): Accumulate result from
1481 free_named_symtab and print warning if we blew user's state.
1482 * symfile.h: free_named_symtab now returns an int.
1484 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1486 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
1487 is the first symbol read, even if not mainline.
1488 (dbx_psymtab_to_symtab): symfile might be zero, cope.
1489 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1490 (set_section_command): New command ("section xxx yyy" -- should
1491 be renamed to "set section xxx yyy" FIXME) which sets the
1492 base address of a section of the exec file, overriding the
1493 virtual address that BFD reports.
1495 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1497 * exec.c: Add add_syms_addr_command to exec_ops, so you can
1498 load symbols at any address while examining an exec file.
1500 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1502 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1503 for printing the float info is host-dependent, not
1504 target-dependent. FIXME.
1505 * i386-pinsn.c: Move #includes to top, remove useless ones.
1506 * i386-tdep.c: Don't bother including <.../reg.h> since we
1507 don't use it (and it doesn't exist on host systems).
1509 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1510 Convert negative numbers properly.
1511 (ieee_test): Make numbers really random; fix format arg.
1513 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1514 * core.c (core_detach): Unpush core_ops, which might not be on
1515 top. We used to just pop the top, which broke things. Don't
1516 need dont_repeat() any more.
1517 (core_file_command): Psst! Don't repeat it.
1518 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1519 * expprint.c (print_subexp): Avoid switch fallthru on
1520 BINOP_ASSIGN_MODIFY, so we can print += and such.
1521 * frame.h: Fix typo.
1522 * inflow.c (kill_command): After killing inferior, print our
1523 current frame in the core file, if we have one.
1524 (generic_mourn_inferior): When inferior dies, either select
1525 the current frame (in the new target, e.g. core file), or
1526 set both the current and selected frames to NULL.
1528 Changes from Peter Schauer.
1530 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1532 * Make all file names fit in 14 characters (sigh and damn!):
1533 mv hp300hpux-xdep.c hp300ux-xdep.c
1534 mv symmetry-xdep.c symm-xdep.c
1535 mv symmetry-tdep.c symm-tdep.c
1536 mv convex-opcode.h convx-opcode.h
1537 mv tm-vxworks960.h tm-vx960.h
1538 mv tm-vxworks68.h tm-vx68.h
1539 mv Makefile.srcdir Makefile.sdir
1540 mv gdb-int.texinfo gdbint.texinfo
1541 mv remote-sa.m68k.shar rem-m68k.shar
1542 mv remote-multi.shar rem-multi.shar
1543 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1544 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1545 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1548 * command.c (user_info_1, user_info): New command for listing
1549 the user-defined commands.
1551 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1553 * dbxread.c (really_free_pendings): Clear file_symbols
1554 and global_symbols after freeing them; otherwise, running
1555 this function twice (if it appears twice on the cleanup
1556 chain), we try to free things twice.
1558 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1559 based on text_addr (the address of text in core), not on addr (the
1560 offset between text in the .o file and in core). This change
1561 is from Peter Schauer.
1563 * main.c: Define ALL_CLEANUPS as a cast of zero.
1564 (return_to_top_level): Use it.
1565 (main): Do all cleanups after each command run as part
1566 of the gdb startup sequence. Also do all cleanups before
1567 entering the command loop, and every time we exit the command
1568 loop and reenter. Before, the cleanups from the startup sequence
1569 were being left undone until the first error!
1570 (command_loop): Rename do_nothing cleanup to command_loop_marker
1571 so we can see it easily when examining the cleanup chain.
1572 (init_signals): Add another do_nothing for signal handling.
1573 (quit_command): Only try to kill target if it has execution.
1574 Problems in the target stack got us into a state where
1575 inferior_pid was nonzero but none of the targets had execution.
1576 In this state you couldn't exit gdb.
1578 * dbxread.c: Two changes from Peter Schauer.
1579 (echo_command): Fflush output after an echo command.
1580 (show_history): Pass all args to cmd_show_list.
1582 * utils.c (init_malloc): Call mtrace to turn on tracing
1583 if the environment variable MALLOC_TRACE is set to a file name.
1584 * mtrace.c: Add source file which provides a log of every malloc,
1585 free, and realloc to a trace file.
1586 * mtrace.awk: Add source file which analyzes the trace file.
1587 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1588 (VERSION): Roll to 3.94.3.
1590 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1591 (check_duplicates): Don't bother with watchpoints.
1592 (set_raw_breakpoint): Comment about danger of this routine.
1593 (watch_command): Parse and eval all args before calling
1596 * solib.c (find_solib): Avoid error in referencing memory to
1597 see if any more shared libraries have been added. This is
1598 particularly useful if the target has terminated. Bug reported
1601 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1602 in bringing up 3.94.2 on the Sun-3.
1604 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1605 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1606 expression (in scope) before reenabling watchpoint.
1607 * signame.c (init_sigs): Add missing declaration of i, fix
1608 sys_siglist declaration.
1609 * source.c (list_command): Fixed range computation to use
1611 * stack.c (backtrace_command): Do not allow command if target has
1612 no stack, print informative error message.
1613 * target.c (target_command): Do not write into command line
1614 because this fails if the target command is used in a user defined
1615 command. [This change was enhanced by gnu to support any-
1616 unique-prefix matching on target names.]
1617 * valops.c (value_struct_elt): Avoid infinite loop on an
1618 erroneous attempt to print the member of function (try p main.p).
1620 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1622 * expread.y (name_no_typename): Avoid reduce/reduce errors
1623 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1624 Since the GDB parser really doesn't use name_no_typename in a
1625 name-only context, the parser can't tell the diff between
1626 names and numbers here. Avoid allowing a name_no_typename
1627 to be a NAME_OR_*INT to resolve the conflict.
1629 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1631 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1633 * valprint.c (val_print_fields): bitfield printing didn't handle
1634 byte order. Indirect through a few more fns to cope.
1636 * values.c (modify_field): also cope with byte order.
1638 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1640 Cleanup for release 3.94.2:
1642 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1643 include files. Roll version to 3.94.2.
1645 * coffread.c (init_stringtab): Read length into unsigned char
1646 array before swapping; don't assume 32-bit longs.
1648 * target.c (target_info): Don't bother with get_sym_file, just use
1649 the symfile global variable.
1650 * symtab.h, symfile.c (get_sym_file): Delete it.
1652 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1653 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1654 (read_type): Replace one more error() with complain().
1656 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1658 * i960-tdep.c: Fix copyright attribution.
1660 * config.gdb: Quote all backquotes in doublequotes. You can
1661 quote me on that. BSD 4.4 shell found this one.
1663 * infptrace.c (throughout): The third argument to ptrace is an
1666 * infrun.c (wait_for_inferior): When program has terminated, we
1667 have to call target_terminal_ours before we pop that target off
1668 the stack (e.g. before a call to target_kill or
1669 target_mourn_inferior). This fixes problem where a program
1670 terminates, then GDB stops for (tty output) and you have to type
1671 "fg" to the shell to resume it. FIXME: This code for what to
1672 do after termination really should be in normal_stop instead.
1674 * gdbcore.h (read_memory_check): Change declaration; it changed
1677 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1678 4.4 prereleases, this avoids a bug in their sgtty compatability
1680 * remote.c: Use terminal.h rather than hand-rolling the same.
1682 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1683 * utils.c (strsave, strstr): Fix arg types.
1684 * valprint.c (val_print): lint
1686 MIPS symbol table support from Per Bothner:
1688 * symfile.c (symtab_fns): Remove initializer table that needs to
1689 be hacked for each new symbol file format supported.
1690 (add_symtab_fns): New function, chains symbol table
1691 handlers into the global list.
1692 (symfile_init): Search this list.
1693 * symfile.h: Add next pointer, declare add_symtab_fns.
1694 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1695 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1697 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1698 symbol *). Thus, we no longer need the hack to trash
1699 pst->filename. Good, since that hack confused code in symfile.c!
1701 (reorder_symtabs, destroy_all_symtabs): Removed static
1702 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1703 Instead, the latter now uses a temporary array (stack-allocated
1704 from an obstack, and then freed).
1706 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1707 haven't been set in the outermost stBlock of a procedure. This was
1708 a problem with f77 binaries on Ultrix 4.?.
1710 (new_symtab, new_symbol, new_type): Continue changing code to use
1711 obstacks more and otherwise conform to dbxread internal style.
1712 Made the free_code of symtabs be free_linetable (as in dbxread)
1713 instead of free_contents. This implies memory leaks when reading
1714 a new symbol table, until the conversion is finished. Did change
1715 (struct symbol) and (struct type) to be allocated on the
1716 symbol_obstack. Blocks and blockvectors are among the things
1719 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1720 tested much, but it solved one problem (reported by Meissner), and
1721 cleans up some other things. The problem happened when an
1722 included file contains actual code (functions) and not just
1723 definitions. The mips coff is a little inconvenient there, since
1724 it may cause a procedure to be mapped to the wrong psymtab.
1726 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1727 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1728 this will need work for the new core paradigm.
1730 Opcode patches from the net:
1732 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1733 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1734 missing altogether - they are added here. From Bruce Bauman.
1735 * mips-opcode.h: The low mask for C0 instructions was too small.
1736 From Garrett Lau. I modified the fix to check the entire 32-bit
1739 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1742 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1744 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1746 * dbxread.c (read_type): Pointer subtraction (value_sub in
1747 valarith.c) sometimes failed because the types of the
1748 pointers being subtracted were not identical.
1749 These differed because dbxread.c was allocating pointer types
1750 using dbx_alloc_type+smash_to_pointer_type instead of
1751 lookup_pointer_type. I failed to find a justification for the
1752 former, so I changed it to use the latter. Similarly, I
1753 replaced smash_to_function_type by lookup_function_type,
1754 and smash_to_reference_type by lookup_reference_type.
1756 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1757 _initialize_mipsread): corresponding changes.
1759 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1761 * source.c (mod_path): Do tilde_expand on each component of the path,
1762 rather than on the (list of) paths as a whole.
1763 (print_source_lines): Set first_line_listed in addition to
1764 current_source_symtab and current_source_line. If the source was
1765 not findable, after a "dir" command to fix the problem,
1766 a "list" would get the wrong lines.
1768 While I was there... (gnu):
1770 * dbxread.c (read_type): Change error to complaint.
1772 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1774 First attempt at detailed understanding of symbol table memory alloc.
1776 * dbxread.c (dbx_symfile_read): Free our string table if we
1777 aren't the mainline. Free the "info" struct since we're done with
1779 (init_psymbol_list): Free any previously allocated psymbol lists.
1780 (): FIXME: Should realloc-down the psymbol lists when done reading
1781 the main symbol file?
1783 * symmisc.c (free_symtab): Free fullname field too.
1785 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1786 (REGISTER_ADDR): Make result type unsigned int.
1788 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1789 define REGEX must also define REGEX1 (its dependency).
1791 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1793 * tconfig/i960: No longer works, points you at vxworks960 or
1796 * xgdb.c, XGDB-README: Remove file. Users can get the much
1798 * Makefile.dist: Remove all trace of xgdb.
1800 * breakpoint.c (breakpoint_1): Pass demangle arg to
1801 print_address_symbolic.
1802 (clear_breakpoints): Remove unused function.
1803 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1804 (breakpoint_re_set): Use catch_errors to do them all anyway.
1806 * gdb-int.texinfo (Host versus Target): Add section on what is
1807 a "host" feature versus what is a "target" feature.
1809 * infcmd.c (path_command, path_info): Handle the PATH variable
1810 (object search path) as conveniently as the source search path.
1811 * environ.c (set_in_environ): Set some vars in GDB's environment,
1812 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1813 * source.c (mod_path): New function, from guts of
1814 directory_command, modifies a path. Used by path_command.
1815 (directory_command): Call it.
1816 * defs.h (strsave): Declare.
1818 * utils.c (sevenbit_strings): Add new printing option.
1819 (printchar): Use it.
1820 (strsave): Provide this handy helper routine.
1821 (set_width_command): Rename set_screen_width_command.
1822 (_initialize_utils): "set screen-width" => "set width";
1823 "set screen-height" => "set height"; add sevenbit-strings.
1825 * infcmd.c (do_registers_info): Print floating point registers
1826 in raw hex as well as float format, regardless of whether it is
1827 a "virtual" convertible register.
1828 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1829 regs as a double, just in case it's being used that way.
1830 * values.c (unpack_long): Comment on array/function coercion.
1831 (unpack_double): Argument is in target byte order now. For
1832 integer arguments, just call unpack_long and float the result.
1833 * m68k-tdep.c: include defs.h for "const" handling.
1834 * remote-nindy.c: Use ieee-float stuff.
1835 (nindy_fetch_registers): Unpack double regs to host double, then
1837 (nindy_store_registers): Pack extendeds to host double, flip
1838 around by misusing unpack_double, send as target double.
1840 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1841 zero, as when stopped at the first instruction of a process.
1843 * blockframe.c: Fix filename in comment (param.h => tm.h).
1844 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1845 * tm-68k.h: Fix typos.
1847 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1849 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1851 * coredep.c (fetch_core_registers): Pass end-address of register
1852 section to register_addr as expected. Don't call supply_register
1853 if we'd just pass it garbage.
1855 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1857 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1859 * target.c (push_target, target_info): Cast enums to int for < or
1862 * stack.c (print_frame_info): Identify source file & line
1863 even if we can't print it.
1865 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1867 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1869 Clean up IEEE floating point support.
1871 * ieee-float.h: New file.
1872 * ieee-float.c: Write real routines to convert between host
1873 doubles and various target IEEE extendeds.
1874 * m68k-xdep.c: Eliminate assembler code for extended floats.
1875 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1876 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1877 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1878 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1879 double_to_ieee_extended.
1880 * i960-tdep.c: Define ext_format_i960.
1881 * m68k-tdep.c: Define ext_format_68881.
1882 * sparc-tdep.c: Define ext_format_sparc, though unused.
1883 * Makefile.dist (HFILES): Add ieee-float.h.
1884 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1887 Obsolete the "coffstrip" program in favor of using BFD's strip.
1889 * nindy-share/coffstrip.c: Remove file.
1890 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1891 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1892 * tconfig/nindy960: Remove reference to coffstrip.o.
1894 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1896 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1898 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1899 * dbxread.c: Remove static symfile_bfd.
1900 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1902 * inftarg.c (child_detach): Pop the child_ops vector if the
1903 detach is successful.
1904 * remote-nindy.c (nindy_create_inferior): Don't push a new
1905 nindy_ops since nindy uses the same one for execution and memory
1907 * core.c (core_ops): Use child_attach and child_create_inferior
1908 rather than default attach and create_inferior functions.
1910 Handle floating point registers in core files.
1912 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1913 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1914 This version untested since BFD doesn't yet support sun3 core
1916 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1917 conventions. Fix comments and style. This version has not
1918 been compiled yet, since we have no HP inhouse.
1919 * core.c (get_core_registers): Look for two sections, ".reg"
1920 and ".reg2", and pass both to fetch_core_registers sequentially.
1922 Revise directory path yet again.
1924 * source.c (forget_cached_source_info): Not static any more.
1925 (init_source_path): New default source path is "$cdir:$cwd".
1926 (dir_command): Handle variable arguments ($cdir, $cwd).
1927 (source_info): Print "Compilation directory" rather than
1928 "Originally compiled in" to remind people of $cdir.
1929 (openp): If the path contains $cwd, use current directory.
1930 (open_source_file): If compilation directory is known, replace
1931 first $cdir in path with the compilation directory.
1932 (print_source_lines): Even if we can't print the lines, set the
1933 current symtab and line for future commands like "info source" or
1934 "breakpoint". Also, error message now contains the file name,
1935 line number, and file access error message.
1936 (_initialize_source): Fix help text to describe changes.
1937 * main.c (cd_command): Forget cached source info when we chdir.
1938 * utils.c (strstr): Add simple implementation.
1940 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1942 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1943 Byte-swap COFF symbol tables if necessary when reading them in.
1944 Use complain() to replace error message in one spot. Needs
1945 corresponding change in bfd/coff-code.h to make some symbol
1946 swapping routines non-static.
1948 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1950 Merge changes from Eirik Fuller, for UTek.
1952 * defs.h (errno): Add declaration.
1953 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
1954 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1955 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,

1958 declarations of errno.
1960 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1962 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1963 <rpc/rpc.h> and <rpc/types.h>.
1965 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1967 * i960-tdep.c (examine_prologue): Add new argument limit,
1968 which stops the scan at the end of the prologue, or at the PC.
1969 This fixes a problem where it walks down into the code for the
1970 user's statements if that code looks like function prologues.
1971 Mark Fox and I have been bouncing this code back and forth, making
1972 small changes to it. Callers changed to match.
1974 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1976 Cleanup for gdb-3.94 release final:
1978 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1979 the .c files from vx-share and nindy-share, from the various
1980 macros, since they are not found via ALLDEPFILES.
1981 (SFILES): Add tm-i960.h.
1982 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1983 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1985 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1986 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

1990 * am29k-tdep.c: Add contribution line.
1991 (examine_prologue): Cache information about function prologues in
1992 the misc-function-vector to avoid lots of references over the
1993 serial line while examining instructions.
1995 * core.c (core_close): New function made from cleanup_core.
1997 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1998 remote-vx.c, remote.c, target.c, target.h,
1999 Update target_ops vector to add attach, close, and load entries.
2000 Use add_syms_addr_command, not add_file_addr_command, for
2001 add_file. Break out close routine from existing code.
2003 * dbxread.c (really_free_pendings): Don't free pending_blocks;
2004 they are in an obstack.
2005 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
2007 (define_symbol): Add symbol type parameter; change callers;
2008 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
2009 it to influence the symbol class on the i960.
2010 (define_symbol): Swap LOC_CONST's into target byte order.
2012 * exec.c (exec_close): New function.
2013 (exec_file_command): Call it.
2015 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
2016 Fix byte order of frame pointer.
2017 (read_var_value): Result of 0 if var's value can't be found,
2018 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
2019 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
2020 (locate_var_value): Use read_var_value and use its lazy address
2021 as the location of the var's value. Lint.
2023 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
2026 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
2027 obsolete Intel versions in favor of vxgdb versions.
2028 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
2029 code dealing with byte order of values, which Intel did in host byte
2030 order rather than gdb-4's target byte order.
2031 (i960_frame_chain_valid): Move to nindy-tdep.c.
2032 (examine_prologue, skip_prologue, frame_find_saved_regs,
2033 frame_args_address, leafproc_return, saved_pc_after_call,
2034 pop_frame): Add vxgdb versions from Mark Fox.
2035 (examine_prologue, frame_struct_result_address): Add code
2036 to deal with the saved value of G13 (struct return address
2038 (frame_args_address): Modify Mark's version to prefer the
2039 saved value over the current value in the topmost frame.
2040 Cache result in the frame info to avoid performance hair in
2042 (print_fault): Add gdb960 code for printing faults.
2043 (_initialize_i960): Actually call check_host.
2045 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
2046 add stub routines. FIXME, these currently just return zero!
2048 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
2049 (attach_command): Call target_attach, not target_open, now.
2051 * infrun.c (normal_stop): Make global, not static, for vx_attach.
2052 (child_attach): Rename from child_open.
2053 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
2054 don't confuse it with a zero step_resume_break_address.
2056 * inftarg.c (child_detach): Eliminate inferior_pid test.
2057 (child_files_info): Clean up message a bit.
2058 (child_ops): Use child_attach, not child_open, to attach.
2060 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
2061 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
2062 findvar.c to here, since it depends on the contents of the
2063 shadow_contents of breakpoints, but keep if #if 0 since it is
2066 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
2069 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
2070 (ptype_command, display_command): Eliminate have_inferior_p and
2071 have_core_file_p in favor of target_has_stack or
2072 target_has_execution.
2073 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
2074 code for actually finding the values of arguments, though we still
2075 keep track of the maximum stack offset for use in printing unnamed
2076 arguments. Handle missing FRAME_ARGS_ADDRESS.
2078 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
2079 (struct nindy_regs): Define registers passed to/from nindy.
2080 (nindy_fetch_registers, nindy_store-registers): Translate between
2081 nindy and GDB formats for the registers.
2082 (dcache_init): Statically allocate the cache, since it was being
2083 allocated by a malloc that was never freed anyway.
2084 (nindy_create_inferior): Error, not core dump, if no exec file.
2085 (nindy_before_main_loop): Use target_load, not target_add_file.
2087 * remote-vx.c (net_load): Specify large timeout for load
2088 requests. Allow user to break out with INTERRUPT.
2089 (net_break): Remove useless code, clean up. Change callers.
2090 (parse-args, skip_white_space, find_white_space): Clean up arg
2091 parsing to cope with quoted strings.
2092 (net_wait, net_quit): Never call error, just return status.
2093 (vx_read_register, vx_write_register): Cleanup status checking.
2094 #ifdef the code based on which CPU we are using (960 or 68k),
2095 FIXME, this should be completely general but it isn't yet.
2096 (vx_xfer_memory, vx_resume): Cleanup status checking.
2097 (vx_run_files_info): Improve message.
2098 (vx_load_command): Renamed from vx_add_file_command. Allow load
2100 (net_ptrace): Remove unused routine.
2101 (vx_wait): Adopt code from vxgdb960 to cope with broken
2102 connections to target machine and prompt to disconnect. Remove
2103 debug printouts. Map some EVENT_'s to SIGnals.
2104 (add_symbol_stub, vx_open): Print names of object files we found,
2105 and "ok" if we read their symbols OK. Clarify output in general.
2106 (vx_attach, vx_detach, vx_kill): Add these commands.
2107 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
2108 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
2109 "info files" output, and create_inferior, since we already have
2112 * stack.c (frame_info): Replace Frame_unknown with 0.
2113 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
2114 (return_command): Pop until the PC matches as well as the FP,
2115 so it works even if the FP is shared with another function,
2116 as in "frameless" or "leaf" procedures.
2118 * symfile.c (load_command): renamed from add_file_target_command.
2119 (add_syms_addr_command): renamed from add_file_addr_command.
2120 (add_syms_command): Stub to call target_add_syms.
2121 (_initialize_symfile): Change command names and descriptions,
2122 add-file => add-syms, and load from alias to its own command.
2124 * target.c (kill_or_be_killed, maybe_kill_then_attach,
2125 maybe_kill_then_create_inferior): Default for attempts to start
2126 a process, if one is already running, is to ask about killing
2127 it and retry if yes.
2128 (upstack_create_inferior): #if-0 it, strata obsolete it.
2129 (push_target, unpush_target, pop_target): to_close() a target
2130 before unstacking it.
2131 (target_info): Renamed from target_files_info.
2132 (_initialize_targets): Rename "i files" as "i target", accessible
2135 * target.h: Improve comments about the target_ vectored routines.
2137 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
2138 Convert commenting style to standard GNU style.
2139 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
2140 (SKIP_PROLOGUE): No longer a no-op.
2141 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
2142 (*_REGNUM): Sort register numbers.
2143 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
2144 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
2145 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
2146 are now 10 byte extendeds, not 8 byte doubles.
2147 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
2148 for nindy versus vxworks targets. FIXME, this should possibly go
2149 in the target vector.
2150 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
2151 frame_saved_regs and arg pointer with each frame.
2152 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
2153 (FRAME_ARGS_ADDRESS): Use cached result.
2154 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
2155 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
2156 (PRINT_RAMDON_SIGNAL): Call print_fault.
2157 (POP_FRAME): Now works.
2159 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
2160 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
2161 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
2162 (ADDITIONAL_OPTION_HANDLER): use target_load, not
2165 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
2166 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
2168 * valarith.c (value_subscripted_rvalue): Avoid handling
2169 floats and doubles specially; it gave alignment errors. Lint.
2171 * valops.c (value_of_variable, value_of_this): Error if unknown
2174 * valprint.c (print_floating): Bcopy rather than pointer-deref,
2175 to avoid alignment problems.
2176 (value_print): Handle unknown value address.
2177 (cplus_val_print): Two args are ignored; remove them. Change caller.
2178 (val_print): Use unpack_long rather than pointer-deref.
2181 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
2182 to avoid alignment problems.
2183 (value_being_returned): Error if return value unknown.
2184 (set_return_value): Add bogosity warning, FIXME. *
2186 * TODO: A woman's work is never done.
2188 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
2189 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
2190 Add ieee-float.o to OBS.
2191 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
2192 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
2193 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
2195 Changes to generalize the VxWorks RPC protocol slightly, to handle
2196 i960 as well as 68000.
2198 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
2199 * vx-share/reg.h: Produce i960 regs #ifdef I80960
2200 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
2201 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
2202 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
2203 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
2204 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
2205 so they will move in target byte order rather than network
2206 byte order (happens to be the same).
2208 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2210 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
2212 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2215 Add contribution lines to various files, showing where they
2218 * breakpoint.c (break_insn, check_break_insn_size,
2219 read_memory_nobpt): Remove to mem-break.c.
2221 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
2224 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
2225 entry has bad register number. This change is not
2226 tested in this release, FIXME.
2228 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
2231 * value.h: Force value's contents field to be aligned to hold
2232 at least a double or a long long (if supported). This avoids
2233 doing bcopy's in and out of the contents field.
2235 (step_1): Avoid coredump under obscure circumstances when we
2238 * symtab.h (misc_info): Add field to misc function vector for
2239 any kind of cached information the target code desires. AMD
2240 29000 uses this to avoid repeating examine_function_prologue's.
2242 * coffread.c: Lint. Remove static symfile, read_section_header.
2243 core.c (have_core_file_p): Lint: remove.
2244 expprint.c (print_subexp): Lint.
2245 infptrace.c, valops.c, valprint.c: lint.
2247 Roll in changes from vxgdb-5.0.1:
2249 * symtab.h: Comment byte order of each address class. Add
2250 LOC_LOCAL_ARG for frame-relative args (960).
2251 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
2252 symtab.c, symmisc.c: ditto.
2254 * infrun.c (init_wait_for_inferior): Clear stop_signal.
2256 * remote.c (remote_resume): Error if resume with a signal.
2258 * symfile.c (prim_record_misc_function): Clear misc_info.
2259 (fill_in_vptr_fieldno): Check stub type of arg.
2261 * valops.c (value_cast): Avoid looking up names of types whose
2262 name we don't know, to prevent coredump. Sun CC produces typedef
2263 rtx and the name of *rtx is zero...
2265 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2267 Roll in changes from final AMD 29000 port (Tiemann).
2269 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
2270 for ../include/a.out.encap.h. This might not work now that BFD
2271 is separately compiled. Instead, BFD support for encap will have
2272 to translate machine type 29k into the right COFF_MAGIC.
2274 * infcmd.c: Remove references to inferior_pid that aren't used
2275 in actual ptrace calls; use target_has_execution, etc.
2276 (have_inferior_p): Remove function.
2277 (program_info): Print target info rather than "process number";
2278 avoid gratuitous messages unless from_tty.
2279 (run_stack_dummy, finish_command): Set proceed_to_finish.
2280 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
2281 main.c: Lint. Lose have_inferior_p().
2282 inferior.h (have_inferior_p): Remove, lint.
2283 (proceed_to_finish): Add flag to ask that all regs be saved
2284 by normal_stop, for the few commands that need it, speeding up
2285 serial I/O. Add comments to stop_registers.
2287 * remote-eb.c: Remove newline from breakpoint message we grep
2288 for. Never time out when running the user program.
2292 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2294 Roll in changes from vxgdb-5.0.1:
2296 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
2297 symbol in its raw form, we are processing an unlinked ".o" file.
2298 See if the target environment has assigned it an address, using
2299 target_lookup_symbol (VxWorks does), and enter it into the symtab
2302 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
2303 68k versions for a simpler version that assumes zero FP at bottom.
2304 Fixes bug of truncated stack reports.
2306 * target.h (target_lookup_symbol): Define this routine's args
2307 and result, finally.
2309 * target.c (nosymbol): Default routine for target_lookup_symbol.
2310 (target_default): Default lookup_symbol and call_function too.
2311 (files_info): Only print has_all_memory warning if a non-dummy
2314 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
2315 vx_convert_from_virtual): If target does not have floating point,
2316 zero register "values", and avoid doing cross-net conversions.
2317 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
2318 (vx_open): Rearrange code that attaches to target and reads
2319 symbols for all loaded modules, to work if some of the modules
2320 are not accessible. Add symbol_stub() and add_symbol_stub()
2321 as callbacks from catch_errors(). Allow connect attempt to be
2322 interrupted painlessly with ^C (FIXME, there are still some bugs
2323 if the interrupt happens during symbol reading.). Print
2324 final message with puts_filtered, since symbol messages are
2329 * main.c (catch_errors): Only print errstring if non-null.
2330 (command_loop): Avoid an ioctl per command to test ISATTY.
2332 * remote-vx.c (net_load): make static; avoid sophomoric msg.
2333 (vx_xfer_memory): Return correct result!
2334 (vx_files_info): Indicate whether target has float or not.
2335 (vx_lookup_symbol): Complain, not error, if target gone.
2336 (vx_open): Print "Connected" msg before disabling immediate-quit.
2337 [FIXME: lookup_symbol and vx_open changes need testing.]
2339 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
2340 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
2341 contributor lines and update copyrights to 1991.
2343 Changes from an attempted H-PUX host port:
2345 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
2346 defines PT_ATTACH and PT_DETACH but not PT_KILL.
2347 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
2348 * remote-vx.c: include <sys/time.h> for HPUX.
2349 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
2350 "core_file_command" routine to BFD regime. May not work yet.
2352 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
2354 * xgdb.c: Replace X10 version with some VJ version.
2355 (FIXME: Its copyright assignment is not on record.)
2356 * xgdb.c: Update include files to X11R4 (Xaw crud).
2357 (xgdb_display_source, create_text_widget): fix call to
2358 get_filename_and_charpos. Rewack source window stuff for X11R4
2359 (gleaned from include files, and "nm's" of binary libraries, since
2360 I had no doc available).
2361 (append_selection, append_selection_word): Disable with FIXME
2362 since R4 changed interface here.
2363 (create_buttons): Add back the old set of buttons.
2364 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
2366 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
2367 Roll VERSION to 3.94 (not yet final though).
2369 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2371 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
2372 obstack_int_grow, obstack_int_grow_fast): Eliminate
2373 cast on left of assignment, which gives MIPS cc fits and is
2376 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
2377 F_ALIAS. Use printf, not fprintf, when not passing a file
2379 (compare_opcodes): Check that identical instructions have
2380 identical opcodes, complain otherwise.
2382 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
2383 was reported by Roland McGrath.
2384 (unimp): Only match if exactly zero instruction. (Roland)
2385 (branches and traps): Generate all variations of these
2386 instructions with macros, based on a single call that defines
2387 each condition name and its binary representation.
2388 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
2390 * valprint.c (val_print_fields): Take, and use, format parameter.
2391 This means that "p/x struct" again prints the elements in the
2392 desired format. Changed callers.
2394 * stack.c (frame_info): Use filtered output, and indicate wrap
2395 points. Remove kludgy formatting designed to avoid line wrap.
2397 * utils.c (wrap_here): If the line is already full (because
2398 we had printed a long indent or long wrapped string), do an
2399 immediate newline-and-indent.
2401 * m68k-pinsn.c (print_insn_arg): Bugfix from
2402 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
2403 instruction is incorrectly disassembled as bkpt #8.
2405 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
2406 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
2407 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
2408 and then will dump core (sometimes). I traced it back to an
2409 uninitialized symfile_name in psymtab_to_symtab.
2410 (const_vol_complaint): Add quotes to message.
2411 (define_symbol): Only believe line number if gcc_compiled.
2412 Avoid allocating symbol if we will not return it.
2414 Add target strata support so that newly established targets go
2415 into their right place in the target stack (e.g. a new exec file
2416 doesn't wipe out the ability to access the running process).
2418 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2419 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2420 and initialize it properly in all the targets.
2422 * target.h: Document strata. Change return type of push_target.
2424 * target.c (nomemory): new function for dummy memory access.
2425 (tcomplain): Rename complain, now also used in symfile.c.
2426 (push_target): Push targets within strata. New return value shows
2427 whether new target is on top of stack or not. Always keep dummy
2429 (target_files_info): Ignore dummy target.
2431 * core.c (core_open): Warn user, and skip accessing file, if the
2432 core target is not the topmost target in the stack.
2433 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2436 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2437 target_ops, it doesn't belong there since we have no regs there.
2438 Change name of target from machine => memory to clarify.
2440 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2442 * Freeze version 3.93 for release.
2444 * Makefile.dist: Handle vx-share and nindy-share subdirs
2445 properly when building gdb.tar.Z.
2447 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2448 printed in various places, so I could change just one copy.
2450 * dbxread.c, coffread.c: Change references to bfd->iostream
2451 to cast to FILE *, now that BFD avoids needing types defined
2452 in other header files.
2454 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2456 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2457 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2458 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2459 (actually gcc -Wall).
2461 * dbxread.c: Remove first_global_sym, last_global_sym, since
2462 they are never referenced.
2464 * defs.h (baud_rate): Declare.
2465 main.c: Define it, and add the -b option to set it.
2467 * gdb-int.texinfo: Add text on how to define a new host or target
2468 architecture, prompted by Per Bothner's questions about MIPS
2471 * gdb.texinfo: Document "complaints". Change doc of -q since
2472 gdb no longer prints the copyright and blurb if you specify a file
2473 name to be debugged (just like Emacs). Add doc for Nindy-specific
2474 command line flags for specifying target serial port and such.
2475 Update copyright to 1991.
2477 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2478 has taken over for us the job of ripping up executable files. The
2479 crud caused Per Bothner's port to not compile.
2481 * infrun.c (normal_stop): Avoid printing "Program exited
2482 normally" if we are in batch mode. This allows a GDB which
2483 executes a program on a target system, to behave like a Unix
2484 command (input from stdin, output to stdout, no extraneous
2487 * main.c (main): Allow additional machine-dependent command line
2488 options to be specified with the ADDITIONAL_OPTIONS,
2489 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2490 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2491 processing to occur just before the main loop with
2492 BEFORE_MAIN_LOOP_HOOK.
2493 (main): If a "core file" argument is specified, and it is not a
2494 core file, try it as a process ID to attach.
2495 (symbol_completion_function): Attempt to cope with
2496 "show screen-" TAB, not very successfully. This needs more work,
2498 (batch_file): New function, returns whether we are reading
2499 commands from an interactive tty on stdin, or from somewhere else.
2500 Called by normal_stop since it doesn't get from_tty passed down
2501 to it like many commands do.
2503 * remote-nindy.c: Handle command line options for nindy
2505 (nindy_before_main_loop): Prompt user for tty name if they
2506 don't specify it before getting to the interactive command loop.
2508 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2509 and -r command line options. Also add hook before main loop
2510 to make it easy to specify a tty.
2512 * TODO: More things to do, one done.
2514 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2516 * dbxread.c: Make complaint() calls pass pointer, not struct.
2517 Add complaints about badly formatted C++ type information
2518 (const/volatile indicator, and parse errors resulting in
2519 error_type). Fix C++ virtual member fn comment.
2520 (read_struct_type): Avoid bumping pointer if we got a parse
2521 error; this prevents our walking beyond the end of a string.
2522 Terminate loop on null char as well as semicolon.
2523 (process_one_symbol): Fix the LBRAC fix so that it uses the
2524 last previous SLINE, FUN, or SO record's PC address. C++ debug
2525 symbols did not have SLINE records in a useful order compared
2526 to the LBRAC records.
2527 (define_symbol): Handle "catch" records.
2529 * symtab.c (check_stub_type): Added new complain
2530 `stub_noname_complain' and added a consistency check to
2531 keep the debugger from crashing when finishing from an
2532 exception frame. A real fix will be needed later.
2534 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2536 * infcmd.c (attach_command): Make global.
2538 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2539 but make them easy to comment out. Perhaps later they should
2540 be enabled by what CPU you configure for? FIXME.
2541 (VERSION): Roll to 3.93.
2542 (pinsn.o): Remove rule for obsolete file.
2543 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2545 Run down a problem that manifested by printing the wrong function
2546 name in stack traces of read_ofile_symtab. Turned out that the
2547 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2548 the LBRAC symbol with an address in the *data* segment, which
2549 blew our binary search through the blocks.
2551 * dbxread.c: Use the complain() facility consistently to bitch
2552 about problems in the symbol file we are reading.
2553 (finish_block): Add code to check the nesting of the blocks;
2554 complain and Procrust them to fit if wrong.
2555 (make_blockvector): Check the order of the blocks, complain
2556 [but don't cope] if wrong.
2557 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2558 symbols to be sure their PC value is greater than the last SLINE
2559 (line number) symbol we've seen, complaining and adopting the
2560 SLINE PC value if wrong.
2562 * symfile.h (struct complaint, complaint_root, complain,
2563 clear_complaints): Add.
2564 * symfile.c (complain, complaint_root, clear_complaints): Add
2565 facility to deal with non-fatal complaints and to regularize their
2567 (symbol_file_add): Clear complaint counters to allow new complaints.
2568 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2570 * dbxread.c (dbx_symfile_read): Remember the address and size
2571 of the string table for the main symbol file, so we won't read it
2573 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2574 to avoid reading the string table yet again. Lint.
2575 (throughout): Improve filtered output, including word wrap.
2576 (read_range_type): Improve Bothner's fix to handle other types too.
2578 * utils.c: Improve line wrap implementation. Handle unlimited
2579 width by making chars_per_line unsigned.
2580 (puts_filtered): New, easy, function.
2582 * defs.h (puts_filtered): add.
2584 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2585 call the identical sort_symtab_syms() in symfile.c instead.
2587 * expread.y: Suggest the `file' command rather than `symbol-file'.
2589 * command.h (enum var_types): Add zinteger for seroable
2591 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2592 nested if's into a switch.
2594 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2595 we did not stop because of a breakpoint (it must have been for
2596 some other reason, like a "stepi"), so don't print anything.
2598 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2599 doesn't include <sys/types.h>, old SunOS's require it for
2602 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2604 A test port of gdb-3.92.6 to the Sony NEWS.
2607 Don't normally link in remote- or vx stuff.
2608 Some of it doesn't compile, and it wastes space for 99% of the users.
2609 Remove reference to no-longer-used HAVE_VPRINTF.
2610 Fixed BFD_DEP typo to BFD_DIR.
2612 Fix cast in arg to bfd_h_getlong.
2613 Make char *prefix be const.
2614 Fix how certain range types are mapped into builtin unsigned int types.
2616 Remove 2 #includes. They cause errors (on Sony, at least),
2617 and aren't needed (they wern't in earlier versions).
2619 print_address_symbolic should never demangle labels
2620 (since it prints *assembler-level* labels).
2622 [This was superseded by the change to printcmd below.]
2625 Add some "volatile" return types to avoid warnings.
2626 If MISSING_VPRINTF add vprintf function and not just macro
2627 (since vprintf is used in printcmd.c).
2629 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2630 (The latter isn't grokked by some PCC-based compilers.)
2632 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2634 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2635 * nindy-share/coffstrip.c
2636 Added some forward declarations (otherwise, gcc complains
2637 about implicit extern redefined as static).
2639 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2641 Changes inspired by Per Bothner:
2642 * printcmd.c (print_address_symbolic): Take additional parameter
2643 specifying whether to demangle.
2644 (print_address): Pass in asm_demangle to control demangling.
2645 (print_address_demangle): New fn, takes explicit arg to control
2647 * utils.c: Add new vars demangle and asm_demangle, and let them
2649 (fputs_demangled): If !demangle, just print the argument.
2650 (fprint_symbol): If !demangle, just print raw symbol.
2651 * valprint.c (val_print): Call print_address_demangle rather than
2652 print_address, to cause demangling to depend on the global
2653 rather than assembler-level demangling setting.
2654 * WHATS.NEW, gdb.texinfo: Document.
2656 * main.c (show_command): Show all settings if no arg.
2657 (initialize_main): Make "info set" the same as naked "show".
2658 * command.c (cmd_show_list): Handle prefix commands in the
2659 list, and print the name of the setting as well as its English
2660 description and value.
2662 Allow gdb functions to specify where a line should wrap if it
2663 exceeds the size of a terminal line. Use it to make the output
2665 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2666 of the right size when screen width changes.
2667 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2668 (wrap_here): New fn, indicates a point in the output where we
2669 should wrap the line rather than just letting it overflow at a
2671 (fputs_filtered): Implement wrapping.
2672 (n_spaces): New fn, returns a pointer to N spaces.
2673 (print_spaces_filtered): Use n_spaces.
2674 * defs.h (n_spaces): Declare.
2675 * stack.c (print_frame_info): Wrap with 4-space indent after
2676 fn name and before filename and line number.
2677 * printcmd.c (print_frame_args): Wrap with 4-space indent
2678 before each argument name is printed.
2679 * valprint.c (value_print): Wrap with no indentation before
2681 (val_print_fields): Wrap with indentation relative to nesting
2682 level before each field name.
2683 (val_print): Wrap with nesting indentation before array elements.
2684 * command.c (do_setshow_command): Avoid extra newlines,
2685 wrap with 4-space indent around values printed, end with period.
2686 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2688 * breakpoint.c (breakpoint_1): Implement addressprint for
2689 "info breakpoints" display. Change file name and line number
2690 format to " at file:nnn" rather than " (file line nnn)".
2691 * gdb.texinfo: Document.
2694 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2696 Frozen for gdb-3.92.6 release.
2698 README, WHATS.NEW: Update for 3.92.6 release.
2700 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2701 coffread.o from configs since it is now built by default.
2702 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2703 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2704 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2705 from configs since it is now built by default.
2707 Makefile.dist: Update for release 3.92.6. Handle files that
2708 have been moved to ../include, ../getopt, or ../bfd. Add
2709 saber.suppress and tests directory. Add config.status to
2710 the release (it will say "none").
2712 coredep.c: Minor formatting fixes.
2714 These changes were made in early December but only checked in now:
2715 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2716 nindy-share/nindy.c: lint
2717 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2718 register values coming back from the target; we store values
2719 in target byte order everywhere.
2721 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2723 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2725 * valprint.c (cplus_val_print, val_print_fields): New functions,
2726 which print C++ objects. They conspire to avoid printing a
2727 virtual base class more than once, following all the twists and
2728 turns of C++ virtual base rules.
2729 (val_print): Call the above rather than do it by hand.
2731 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2732 symbol file, not for added files like shared libs. This really
2733 needs to be generalized to a timestamp per file.
2735 * core.c (cleanup_core): Avoid coredump if no core file.
2737 * config.gdb: Accept -host or -target in place of +host or
2740 * coffread.c (find_linenos): Avoid desupported BFD interface
2741 to line numbers. We still read them manually rather than using
2742 BFD's "generic" features.
2744 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2746 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2748 * Makefile.dist: Eliminate use of $< in explicit targets.
2750 * readline/Makefile: Use $< rather than $*.c, which does not
2751 include the VPATH in GNU Make.
2753 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2754 copies of tconfig/i960, added for global configuration
2755 compatability. All i960 versions can read both coff and b.out.
2757 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2758 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2761 * TODO: Think of more things to do.
2763 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2765 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2766 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2767 64-bit float conversion.
2769 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2770 equivalent to sun?os4 so global config works.
2772 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2774 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2776 * main.c: Only declare linesize once; declare pagesize not at
2777 all, since it is never used.
2778 (main): Clear newly allocated line before it is used.
2780 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2782 Further stabilization for the Intel 960.
2784 * Makefile.dist: Parameterize the location of the "include"
2785 and "bfd" directories, as well as "getopt". Add symfile.c.
2786 Link in both dbxread and coffread. Fix up "make depend" to
2787 rewack the locations of include, bfd, and getopt in its output.
2789 * README: Document moving include files, improve some of
2792 * coffread.c: Move common code out to symfile.c. Change
2793 symbol_file_command style interface to use new *_symfile_init
2794 and *_symfile_read interface under BFD. Use BFD internal
2795 info to locate line table, symbols, etc.
2797 * core.c (core_fetch_registers): Rename to get_core_registers
2798 to avoid confusion with fetch_core_registers.
2799 (register_addr): Move to coredep.c, which is already machine
2800 dependent. This leaves core.c pretty clean of dependencies.
2802 * coredep.c (register_addr): Accept this routine from core.c.
2804 * dbxread.c: Move common code (with coffread.c, etc) into new
2805 symfile.c. Each psymtab now contains a pointer to the
2806 format-dependent function that knows how to read it in. Make
2808 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2809 (process_one_symbol): Add code to complain about a "compiler bug
2810 we muzzle here", if we actually see it.
2812 * eval.c (evaluate_subexp): Insert missing "break" statements
2813 in code that determines whether a variable is an lvalue in
2814 memory, register, or whatever. I detected this via a compiler
2815 bug in which it *almost* mashed out the whole switch statement.
2817 * gdb-int.texinfo: Add minor sections on configuring gdb for
2818 release, and about the README file.
2820 * infcmd.c (registers_info): Fix formatting somewhat. Still
2821 not as pretty as before, but it handles byte swapping.
2823 * remote-nindy.c: If data cache routines are interrupted while
2824 waiting for the remote end, be sure that any uninitialized cache
2825 blocks are on the free list, not on the valid list!
2827 * symfile.h: Flesh out this header file with all the various
2828 routines and variables that have been merged in from dbxread.c
2829 coffread.c, and symtab.c to symfile.c.
2831 * symfile.c: New file, containing code common to dbxread.c,
2832 coffread.c, and some code from symtab.c. All generic code for
2833 reading symbol files should be in here now.
2834 (unrecord_misc_function): Remove unused function.
2836 * symtab.h: Remove file-reading things to symfile.h.
2838 * symtab.c: Remove file-reading things to symfile.c.
2840 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2841 to decode i960 fault types.
2843 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2844 target.c: Change type of the "resume" function from int to void,
2845 since its result was never used.
2847 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2849 * main.c: Replace "stupid" with "caution"; you now "set caution
2852 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2854 * infcmd.c (do_registers_info): Call val_print to deal with the
2855 byte order of the registers being printed. FIXME, this makes
2856 the formatting of the output uglier.
2858 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2859 defined, call it for signals the debugger doesn't itself use.
2860 The i960 uses this for more detailed fault information.
2862 * remote.c (remote_open): If arg is null, print help rather than
2865 * sparc-xdep.c (register_valid): Avoid declaring size, since
2866 various modules will think of various sizes depending on the
2867 architecture of their tm-file. FIXME, we need protection against
2868 actually entering one of those modules, which would clobber
2869 storage if not for the target architecture compiled into gdb.
2871 * stack.c (up_command, down_command): Always print the frame
2873 (up_silently_command, down_silently_command): New commands
2876 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2878 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2879 more parameters than it used to.
2881 * findvar.c (registers): Increase slop to 256 bytes, which should
2882 protect us against even most RISC machines with large register
2884 (locate_var_value): Move declaration inside related ifdef.
2886 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2887 throughout, to avoid throwing away buffered input from the board.
2888 (nindy_wait): Supply_register takes addr_of_value, not value.
2889 (i960_print_fault): Renamed from i80960_fault.
2890 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2891 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2893 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2894 we can set the PC in the call to proceed(). Unpush nindy_ops
2895 before pushing it on top, to avoid message to user. Eliminate
2896 commentary from Unix machines that just misleads here.
2897 (reset_command): Fix error message to suggest target command.
2899 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2901 Release 3.92.5 as frozen.
2903 Stabilize the merged release...with help from lint, Saber C,
2906 Everywhere: Add include files needed to declare return types
2907 of functions called.
2909 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2911 * breakpoint.h: Add undeclared breakpoint functions, and some
2912 functions for display handling since I couldn't think of a better
2915 * breakpoint.c (insert_breakpoints): Make code for disabling
2916 shared library bkpts more likely to work. It's used when we
2917 rerun a program and stop before the shared library has been
2919 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2920 cast from pointer, so it squeezes through catch_errors.
2921 (bpstat_stop_status): Fix logic broken some time ago. We now
2922 always create a bpstat if the stop address matches a breakpoint,
2923 even if we don't stop there -- just like the old code used to do
2924 before I got my fingers into it (sigh).
2925 (breakpoint_1): Print "ignore count" after "stop only if"
2926 condition, since that's how it actually works.
2927 (mention): Handle watchpoints as well as breakpoints.
2928 (watch_command): use set_raw_breakpoint and mention to do most
2929 of the work (and initialize all the fields!). Only pass one
2930 arg to parse_c_expression, since that's all it takes.
2932 * command.c (not_just_help_class_command): Rename arg to args
2933 since we ignore "unused argument" warnings on vars named "args".
2934 inflow.c (child_terminal_info): ditto.
2935 infptrace.c (kill_inferior): ditto
2936 main.c (catch_errors, version_info, quit_command, pwd_command,
2937 source_command, dump_me_command, editing_info,
2938 set_history_size_command, set_history, show_history,
2940 stack.c (locals_info): ditto
2941 target.c (target_files_info): ditto
2942 valprint.c (set_input_radix, set_output_radix): ditto
2944 * core.c: Remove old variables for handling core and exec file
2945 sections (data_start, data_end, stack_start, stack_end,
2946 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2947 text_end, exec_data_start, exec_data_end, text_offset,
2948 exec_data_offset, data_offset, stack_offset). They're
2949 superseded the more general build_section_table and
2951 (get_exec_file): Mention the `file' command.
2952 (read_memory_check): Rename to memory_error, and only call it
2953 in the case of an actual error.
2954 (read_memory, write_memory): call memory_error.
2955 (core_fetch_registers): Register section name is ".reg".
2957 coredep.c: Remove a bunch of crud now that all this file does
2958 is pull the registers out of a core file.
2959 (fetch_core_registers): Rewrite to actually work, I hope.
2961 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2962 Replace index() with strchr(). Remove all the pre-BFD macro
2963 definitions for accessing the symbol file.
2964 (struct dbx_symfile_info): Encapsulate the information that
2965 dbx_symfile_init needs to pass to dbx_symfile_read in this
2968 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2969 dbx_symfile_discard): Rearrange symbol file reading to divide
2970 the format-specific part from the format-independent part,
2971 leaving the format-independent part such as file name expansion
2972 and opening in symtab.c. This replaces
2973 partial_symbol_file_open and partial_symbol_file_read.
2974 Symbol_file_read, add_file, add_file_target_command,
2975 add_file_addr_command move to symtab.c. Pass an explicit
2976 "mainline" flag for when reading the main symbol table, rather
2977 than relying on the offset address to be zero or nonzero.
2979 (dbx_symfile_read): Don't allow void *'s to be printed as
2981 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2982 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2983 macro" debug version really work.
2984 (read_dbx_symtab): Remove unref'd parameter inclink.
2985 Avoid swapping N_SLINE symbols, for speed.
2986 Merge N_TEXT!N_EXT case with the other external symbol
2987 definitions' case. Add comments.
2988 (start_psymtab): Allocate the symfile name in the psymtab on
2989 the psymbol_obstack, rather than using the caller's storage.
2990 (end_psymtab): Only allocate a dependencies list if there are
2992 (psymtab_to_symtab_2): Use BFD when reopening file to read
2993 its symbols for real.
2994 (read_struct_type): Add FIXME comments where it needs work
2996 (read_huge_number): Add FIXME about overflows.
2997 (read_range_type): Add FIXME about comparing a long to 1<<32.
2999 * coffread.c: Minor changes to move things closer to the new
3000 regime with symtab.c and dbxread.c Major work is still needed
3003 * exec.c (exec_file_command): Remove old variables (see core.c
3005 (xfer_memory): If memory transfer is right at the end of a
3006 section, don't lose.
3008 * findvar.c (get_saved_register): If value is in a real
3009 register, LVAL is lval_register, not lval_memory.
3011 frame.h: Declare print_sel_frame and record_selected_frame.
3013 gdb-int.texinfo: New file, for GDB internals documentation.
3014 Very simple, unformatted doc of cleanups is there for now.
3016 gdbcore.h: Remove obsolete variables that described a.out
3017 section addresses and offsets. (See core.c above.)
3018 Declare fetch_core_registers and registers_fetched.
3020 getopt.c: Declare char *alloca(); even on SPARC.
3022 infcmd.c (run_command): Call target_kill rather than
3024 (step_command, next_command, stepi_command, nexti_command):
3025 Declare from_tty parameter even though we don't use it.
3026 (run_stack_dummy): argument BUFFER is a char array, not
3027 a pointer to REGISTER_TYPE.
3028 (finish_command): using_struct_return needed a value *,
3029 not a struct symbol *.
3031 * infptrace.c (child_xfer_memory): To avoid dependency on
3032 where sections are in memory, try PT_WRITE_D and if that fails,
3033 try PT_WRITE_I. Most Unixes don't care which you use.
3035 * infrun.c (step_resume_break_shadow): Change to array to
3036 match other breakpoint shadow storage.
3037 (clear_proceed_status): Pass address of bpstat to
3038 bpstat_clear, not the bpstat itself.
3039 (child_create_inferior): FIXME comment about if the child
3041 (start_inferior): Remove old function.
3042 (child_open): Use target_kill rather than kill_inferior.
3043 (wait_for_inferior): Ditto.
3044 (insert_step_breakpoint, remote_step_breakpoint): Use
3045 new step_resume_break_shadow.
3047 * inftarg.c (child_wait): If all child processes die,
3048 pretend that the one being waited for exited with signal 42.
3050 * main.c (command_line_input): When scanning for comments,
3051 don't coredump on unclosed quotes.
3052 (quit_command): Use target_kill rther than kill_inferior.
3053 (_initialize_main): Rename class_user from "user" to
3056 * printcmd.c (print_command_1): Initialize "fmt" if no format
3057 is specified by the user.
3058 (print_frame_args): Only add to args_printed if we are
3059 actually fetching args from the stack (avoiding undefined
3061 (_initialize_printcmd): Remove bogus \{ from string.
3063 * remote-eb.c (eb_open): Avoid coredump on no argument.
3065 * remote-nindy.c: Bring out of Intel environment into new
3066 target environment. Remove all conditional compilation on
3067 I80960. Massive hacking throughout.
3068 (nindy_xfer_inferior_memory): New routine stolen from
3070 (nindy_create_inferior): New routine pieced together, probably
3071 not quite working yet.
3072 (nindy_ops): New target_ops struct for nindy.
3074 * remote-vx.c: Use write_memory rather than target_write_memory
3075 to get error checking.
3076 (vx_add_file_command, vx_open): Use symbol_file_add rather than
3078 (vx_create_inferior): Use target_terminal_ours...
3080 * signame.c (_initialize_signame): Always initialize, since
3081 we need the table for things other than psignal.
3083 * solib.c (solib_add): Use symbol_file_add, not add_file.
3084 (solib_address): Return boolean result rather than struct
3085 pointer which nobody else knows the type of.
3087 * sparc-tdep.c, valops.c: Use write_memory rather than
3088 target_write_memory, to get error checking.
3090 * stack.c (locals_info, catch_info, args_info,
3091 get_selected_block, frame_command, up_command): Use
3092 target_has_stack, rather than have_inferior_p or
3095 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
3097 * symfile.h: New file, defining the interface between the
3098 generic and object-file-specific symbol reading code.
3100 * symtab.c: Move generic symbol-reading interface to symtab.c,
3101 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
3102 table to map BFD targets to symbol-reading modules in GDB.
3103 Change index to strchr.
3104 (lookup_struct_elt_type): Use error() rather than hand-made
3105 simulations thereof.
3106 (lookup_partial_symbol): Speedup slightly when length == 0.
3107 (symbol_file_add): New function.
3108 (symbol_file_command): Call it.
3109 (symfile_open, symfile_init): New function.
3110 (add_file_target_command, add_file_addr_command): moved from
3113 * target.c (target_command): use target_kill.
3115 * target.h (target_files_info): Don't declare, never called
3118 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
3119 files to determine stack end address.
3121 * valarith.c (value_x_binop, value_x_unop): Change error message
3122 to be more useful. Pass proper argument to value_struct_elt.
3124 * valops.c (value_assign): FIXME comment that long long
3125 bitfields will break here.
3127 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
3128 Update `make saber_gdb' to work better.
3130 * TODO: A woman's work is never done.
3132 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
3133 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
3134 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
3135 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
3136 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
3137 valops.c, valprint.c, exec.c: Lint.
3140 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
3142 Continuing Intel 960 port merge of GDB.
3144 * Makefile.dist: Merge i960 "nindy-share" files. Rename
3145 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
3146 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
3147 Wack over "make depend" so it handles files in subdirectories
3148 vx-share, nindy-share, bfd, and in the current directory.
3150 * blockframe.c (get_prev_frame_info): Remove fatal error
3151 if stack not defined.
3153 * core.c (core_open, core_detach): New functions that handle
3154 the old "core-file" command as "target core" and "detach" instead.
3155 (core_file_command): Call them.
3156 (core_xfer_memory): Use common routine xfer_memory.
3158 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
3159 dbxread now uses bfd for everything but symbol reading itself.
3160 BFD internals are used to drag out the relevant file offsets.
3161 (partial_symbol_file_open): Change args all around for BFD.
3163 * symtab.c: Rename "value" to "val" everywhere, so we can
3165 (symbol_file_command): New command, moved from dbxread.c
3166 and coffread.c. It uses BFD to read the file, then vectors
3167 based on its type, to dbx or coff symbol readers.
3168 * symtab.h: Extern a few vars for symbol_file_command.
3170 * target.h: Breakpoint takes a char * save area, not a char **.
3172 * valprint.c (val_print): When unpacking bitfields, offset
3173 the address in gdb of the value, if it is declared with a shorter
3174 type. Remove the last "runtime kludge test" of host byte order.
3176 * utils.c: Remove old my_bfd_read routine.
3178 * stack.c (frame_info): Use target_has_stack. Print program counter
3179 register's actual name rather than "pc", since it's called the
3180 "ip" (instruction pointer) on the i960 (sigh).
3182 * target.c (target_command): Add command for selecting a target
3183 type and calling its open routine. This is used for initiating
3184 communication with a particular target, in a generic way.
3186 * tm-i960.h: Update for modern gdb. Remove semicolons from
3187 various macros. Handle reading struct return convention, and
3188 error-out attempts to return structs with the "return" command.
3189 Be sure gdb doesn't think we know how to call functions in the
3192 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
3193 to i960_xxx in lower case.
3194 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
3195 not being defined yet.
3197 * remote.c (remote_open): Call start_remote to initialize
3198 wait_for_inferior during open.
3199 (remote_xfer_inferior_memory): Return length written rather
3202 * remote-vx.c (target_command -> vx_open): Use new generic
3204 * remote-eb.c, inftarg.c, exec.c: ditto.
3206 * infrun.c: Fix comments.
3207 (attach_program -> child_open): Use new generic target command.
3208 (wait_for_inferior): Clear saved register values before target_wait,
3209 so target_wait can set some of them if convenient.
3211 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
3212 Return success indicator, not void.
3213 (child_xfer_memory): Avoid fetching initial word if we'll
3214 overwrite it anyway.
3216 * infcmd.c (attach_command): Use new generic target open routine.
3217 (_initialize_infcmd): Update doc on attach and detach commands.
3218 (do_registers_info): Merge in a byte-order problem as a FIXME
3221 * findvar.c (find_saved_register): Avoid problem in current frame.
3222 (read_relative_register): Ditto.
3223 (write_register): Convert byte order on the way out.
3225 * exec.c (file_command): Add.
3226 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
3227 (xfer_memory): Common function between core_xfer_memory and
3229 (exec_xfer_memory): Use it.
3231 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
3233 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
3234 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
3235 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
3237 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
3239 Merge Intel 960 port of gdb, continuing...
3241 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
3242 symbol_file_command): Pass from_tty arg to hush 'em up.
3244 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
3245 Add magic numbers for 960 COFF format.
3247 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
3249 Merge Intel 960 port of gdb, from Intel "1.2" release.
3251 CHANGE_LOG entries from their port, which was based on
3254 Thu Sep 6 11:02:22 PDT 1990
3255 Remove temp file if download is interrupted.
3257 Wed Aug 1 09:08:33 PDT 1990
3258 Now uses binary protocol to talk to NINDY.
3259 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
3260 Times out after 5 seconds when trying to talk to NINDY.
3262 Tue May 29 12:54:49 PDT 1990
3263 Added variable baud rate (-b switch).
3264 Source code reorganization.
3266 Thu Apr 26 11:09:55 PDT 1990
3267 More cleanup of batch mode; specifically, execute "-s", "-e", and
3268 "-se" switches as soon as they are encountered on the invocation line.
3270 Fri Apr 20 13:47:15 PDT 1990
3273 Thu Apr 19 09:54:28 PDT 1990
3274 Add 'reset' command.
3276 Wed Apr 18 09:48:07 PDT 1990
3277 After opening remote tty, wait for 1 second to go by without input
3278 from it before trying to talk to NINDY (fixes problems with the
3279 Heurikon HK80/V960E).
3281 Mon Apr 4 16:33:05 PDT 1990
3282 Some output was not being suppressed in 'batch' mode.
3284 Thu Mar 22 15:31:11 PST 1990
3285 Ask user if old symbol table should be deleted when new file is
3288 Allow user to run a program downloaded before gdb960 was brought up.
3290 Correct "exec-file" help message for i80960 context.
3292 Correct bug in calculating user space address: could occasionally
3293 corrupt user program.
3295 Make sure to zero low-order bits in rip's because of bug in 960CA
3296 A-step part: could cause operation faults when "next"ing across
3299 Correct bug that made it impossible to get source line numbers for
3300 code loaded at addresses higher than 0x7fffffff.
3302 Wed Jan 10 12:43:22 PST 1990
3303 Open remote tty for exclusive use.
3305 Fri Jan 5 12:14:42 PST 1990
3306 Correct disassembly (CA manual was right after all):
3307 opcode for sysctl is 0x659
3309 Mon Oct 23 12:03:04 PDT 1989
3310 Use G960BASE and G960BIN environment variables to find 'sx' utility.
3312 Mon Oct 16 14:15:09 PDT 1989
3313 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
3315 Mon Oct 2 15:56:31 PDT 1989
3317 Added 960CA disassembly support.
3319 To simplify maintenance:
3320 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
3322 - eliminated opcode.h: incorporates tables into i960-pinsn.c
3323 - moved 960-specific routines from i960-pinsn.c to i960-md.c
3324 - made disassembly interface identical to that in gdmp960.
3328 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
3330 * target.h: Allow targets to stack. Add target_has_memory,
3331 _registers, etc. Restructure memory access and "info files"
3332 to walk the target stack.
3333 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
3334 target.c: Change tables to match target.h.

3339 * remote-eb.c: New memory regime, new info files.
3340 * remote-vx.c: New memory regime, new info files. Now use
3341 separate targets for VxWorks attachment to machine, and
3342 actually running a process under VxWorks, since one has
3343 stack & execution & regs and the other doesn't.
3344 * remote.c: New memory regime, new info files.
3345 * sparc-xdep.c (fetch_core-registers): New memory regime.
3346 * target.c: New routines and support for stacked targets,
3347 new memory regime, new info files regime.
3350 Generalize section handling for an arbitrary number of sections,
3351 including use of the new BFD (binary file) library.
3352 * gdbcore.h: Add struct section_table.
3353 * exec.c (build_section_table): Iterate all sections and
3354 record what gdb needs to know about them.

3361 * dbxread.c: Quick changes to make it compile with new BFD.
3362 * utils.c (error): Avoid using bfd_error in generic routines.
3364 * core.c (core_fetch_registers): Get from the ".regs" section of
3366 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
3368 * inferior.h (attach_flag): Export.
3369 * infcmd.c (run_command): use new target_create_inferior.
3370 * infrun.c (child_create_inferior): Don't return result.

3376 since been deleted, such as temporary breakpoints.
3377 infcmd.c (program_info): ditto.
3379 * core.c (core_file_command): Display the frame where the core
3384 * remote-vx.c (target_command): Merge in target command from
3385 targ-vx.c. A few other cleanups.
3387 * TODO, Projects: Lots more stuff to do...
3389 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
3391 Massive changes to wall off the remote-debugging interface
3392 behind a function vector. The port to handle VxWorks targets
3393 is also part of this.
3395 All files: Replace references to renamed functions,
3396 remove references to remote_debugging, remove references to
3397 have_include_file, have_core_file in favor of target_has_stack,
3398 target_has_memory, etc.
3400 * Modularize the breakpoint interface.
3401 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
3402 a breakpoint instruction.
3403 breakpoint.c: struct breakpoint's shadow_contents now sized as
3405 (insert_breakpoints): Vector to target to install breakpoints.
3406 (remove_breakpoints): Vector to target here too.
3407 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
3408 sparc-tdep.c (single_step): Use new breakpoint interface for
3409 the single-step breakpoints.
3410 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
3411 New file, contains routines to insert and remove breakpoints by
3412 reading out the old contents and later replacing them. This is
3413 how ptrace breakpoints work, and many remote systems as well.
3415 * tm-vxworks68.h: New config file, overrides a few things for
3416 Wind River's preferences.
3418 * target.h: New file, for transfer vector used to talk to the
3419 inferior (child, attached, core, exec, remote, etc). All accesses
3420 to the thing being debugged should come through these vectors.
3421 target.c: New file, routines to handle transfer vector.
3422 (various files): Add transfer vectors XXX_ops for the various
3423 targets and pseudo-targets (core files, etc) we support.
3425 * breakpoint.c (bpstat_stop_status): Further explorations of
3426 watchpoints and why things don't work all the time.
3427 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3429 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3430 the local gdbinit if it doesn't already have it.
3432 * core.c (core_ops): add and install.
3433 Allow core debugging without exec file.
3435 * dbxread.c (free_and_init_header_files): Merge two fns.
3436 (end_symtab): Free named symbol table when a new version comes in.
3437 (read_dbx_symtab): Relocate all kinds of symbols with base
3438 address. First step toward handling different text, data, bss
3440 (add_file_addr_command): Renamed add_file_command.
3441 (add_file_command): Vector to remote handler.
3442 Add "load" as an alias for "add-file" command.
3444 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3445 non-returning functions.
3447 * exec.c: Add exec_ops, and push it as a target when an exec
3450 * infcmd.c (run_command): Pass executable file name and arg list
3451 separately when starting an inferior. Permit "run" when no exec
3452 file is specified, for VxWorks.
3453 (detach_command): Move to child_detach in inftarg.c.
3455 * inftarg.c: New file. Unix-child-specific routines, and the
3456 child_ops structure.
3458 * inferior.h (registers): Export "registers" as the way for
3459 target dependent register handlers to find gdb's local copy of
3460 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3461 since it is now used by places that want wait_for_inferior to
3462 handle the grunge but want to see every trap from the inferior.
3464 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3465 Eliminate remote_debugging hooks in terminal handling.
3467 * infrun.c: Replace start_inferior with child_create_inferior.
3468 Move all the hair of Unix shells and ptrace idiosyncracies into
3469 child_create_inferior, so remote handlers don't have to deal.
3470 Remove running_in_shell. Rename stop_after_attach to
3471 stop_soon_quietly, and use it in a few other places where we want
3472 to just call wait_for_inferior and get control back on the first
3473 trap. trap_expected now never takes a value > 1.
3474 (init_wait_for_inferior): Initialize static vars when a new
3477 main.c (gdbinit): Add new hook for .gdbinit file name, let
3478 it be overridden by config files as GDBINIT_FILENAME.
3479 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3480 Both of these are used for VxWorks gdb.
3482 mcheck.c: rename include file "gmalloc.c" to avoid problems
3483 with system include file "malloc.c".
3485 param-no-tm.h: New include file, same as param.h but does not
3486 include the default "tm.h" file. This is used in files where
3487 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3489 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3491 remote-vx.c: New file, VxWorks remote debugging support. Uses
3492 RPC routines that are shared with the target system, in directory
3495 remote.c: Vectorize remote interface.
3497 source.c: Globalize source_path, and make an alias "l" for "list"
3498 since we now have the "load" command.
3500 sparc-xdep.c: Use new param-no-tm.h.
3502 symmisc.c (free_named_symtab): Add new function from Wind River.
3503 However, ifdef it out for now while we think about what it should
3506 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3508 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3509 non-Unix-children handle this with their own code in the target
3512 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3513 source and target lists. Add vx-share to default list of include
3514 directories. Add new files to src and target lists: mem-break,
3515 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3516 ${srcdir} versions of munch and createtags are used.
3518 * valops.c (find_function_addr): Split out of call_function.
3519 (call_function_by_hand): Rename call_function; this function
3520 calls functions in the target by laboriously patching the target
3521 word-by-word with the right stack, args, regs, etc.
3524 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3526 Handle AMD 29000 a bit better.
3528 * remote-eb.c (readchar): Mask received char log to make it readable.
3529 (remote_start): Pass arguments down to executing program.
3530 Make startaddr unsigned.
3531 infrun.c (start_inferior): Accept args, pass them to
3533 infcmd.c (run_command): Pass args down to start_inferior.
3535 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3536 the target object file format.
3537 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3539 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3540 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3542 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3544 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3545 * TODO: We did a few things, we have more to do though.
3547 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3548 * inflow.c (inferior_died): Clear deferred stores.
3550 * Debug problems with dummy frames and calls to the inferior.
3551 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
3552 * sparc-tdep.c (do_restore_insn): Simplify.
3553 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3554 (sparc_push_dummy_frame): Simplify and fix what we push.
3555 (sparc_pop_frame): Slightly more hair here, deciding whether
3556 we are restoring a saved PC or returning to a return address in %i7.
3557 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3559 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3560 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3561 * obstack.h (chunkfun): ditto.
3562 * defs.h (xmalloc, xrealloc): ditto
3564 * utils.c (quit): Grab the terminal from the child if necessary.
3566 * inflow.c (term_status_command): Rename to term_info, change
3569 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3570 (is_delayed_branch): Speed up.
3571 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3572 Still missing some float ops, and needs testing.
3574 * Support for input and output radixes other than base 10
3575 * defs.h (input_radix, output_radix): Declare.
3576 * expread.y (yyparse, parse_number): Handle changes of input
3577 radix, and ambiguous names-or-numbers in radixes >10.
3578 * printcmd.c (print_scalar_formatted): Print formatted hex
3579 numbers in varying column widths.
3580 * valprint.c (val_print): Use output_format to print scalar ints.
3581 (set_input_radix, set_output_radix, set_radix): Create.
3582 (set_output_radix): Set output_format from output_radix.
3583 (_initialize_valprint): add `set radix' but leave the others off.
3585 * main.c (execute_command): Let stupid questions be turned off.
3586 (_initialize_main): Handle "set stupidity", etc.
3588 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3589 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3591 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3593 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3594 bfd stuff is still screwed up, but with some manual work, it
3597 * breakpoint.c (bpstat_do_actions): Start over if a command
3598 proceeds the inferior, since the inferior will have stopped and
3599 will need to have its new stop-actions taken care of.
3601 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3602 compiler fits, simplify it.
3604 * gdb.texinfo (directory command): Doc new dir command.
3605 source.c (directory_command): "dir" now puts things on the front
3606 of the path, moves dups up front, and handles multiple names
3607 on the command line, inserting each one in order. It also
3608 blows away cached line and full_filename info.
3610 * stack.c (backtrace_command): Skip "more stack frames follow"
3613 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3614 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3615 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3616 The only odd one was Gould NP1, which had defined vprintf to
3619 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3620 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3621 variable, inspect_it.
3622 valprint.c (print_string, val_print): Use the global inspect_it
3623 to indicate whether to print in Epoch style or normal style.
3625 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3627 * printcmd.c (call_command): add an alias for the "print" command
3628 which runs expressions and doesn't print the result if void.
3629 (print_command_1): implement it.
3631 * command.c: Remove #if 0'd code. Initialize all the fields
3632 in add_cmd (). Rename do_nothing_command to
3633 not_just_help_class_command, and make it externally visible.
3634 command.h: add user_commands to struct.
3635 * main.c (define_command): Don't overload c->function with a char
3636 string as well as a function pointer.
3638 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3639 calling convention of value_struct_elt () that got dropped in
3642 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3643 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3645 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3647 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3648 until a good time (e.g. when we are about to run the child),
3649 saving ptrace calls.
3650 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3651 * tm-sparc.h: define DO_DEFERRED_STORES.
3653 * sparc-xdep.c (store_inferior_registers): when storing float
3654 registers, don't store stack regs too. When storing the SP,
3655 however, DO store the stack regs too. This fixes a bug in which
3656 the dummy frame is not recognized when a call_function finishes,
3657 because its frame pointer (in the stack regs) was never
3659 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3660 even though we don't know how to read them from an inferior.
3661 valops.c (call_function): Comment about storing SP.
3663 * infrun.c (save_inferior_status): Save away the original bpstat
3664 chain so it can be restored later. Install the copied version for
3665 use by whoever saved the status. It will be blow away by
3666 restore_inferior_status, and the original chain restored. This is
3667 important for people who have pointers into the original.
3669 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3670 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3671 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3674 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3676 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3677 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3678 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3680 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3682 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3683 Store the baseclasses in a type struct starting from array element
3684 0 rather than from the unusual array element 1.
3686 dbxread.c: the above.
3687 (virtual_context): Add
3688 Read new debug information about which virtual function table
3689 a virtual function is from, and store it in fn_field.fcontext.
3691 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3692 TYPE_FN_FIELD_STATIC_P.
3694 symtab.c: the above.
3695 valops.c: the above. Handle pointer casts of object *'s.
3696 (search_struct_method): Add.
3697 (value_struct_elt): First arg is now a pointer to a value, and is
3700 valprint.c: the above.
3701 values.c (value_virtual_fn_field): Add type arg. Handle
3702 offsetting to the proper object when calling virtual fns.
3704 (baseclass_addr): Add valuep arg.
3706 * README: Document the current state of BFD config (missing).
3707 * TODO, ChangeLog, Makefile.dist: Roll version.
3708 * WHATS.NEW: Add summary of changes since 3.5.
3710 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3712 * dbxread.c (read_struct_type): Clear bit vectors whenever
3714 symtab.c (B_CLRALL): define.
3716 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3717 using == rather than =. Huh... This fixes the dreaded problem
3718 wherein builtin_type_int becomes TYPE_CODE_FLT.
3720 * core.c (info_files): Show the inferior pid.
3722 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3723 already knows how to look in the source directory.
3725 * Remove psymtab hair from many places. Remove duplicated code
3726 for searching symbol tables. Hide psymtabs from most places.
3727 Make it fast to get from a psymtab to its symtab.
3729 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3730 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3731 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3732 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3733 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3734 new symtab completely. New psymtabs get symtab pointer
3735 initialized to zero. Remove MI warning printf.
3736 symtab.h: Comments. Add psymtab to symtab pointer.
3737 (PSYMTAB_TO_SYMTAB): New macro.
3738 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3739 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3741 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3743 (print_frame_info): Avoid special-casing symbols that have not yet
3746 * source.c (open_source_file): Quick path if we have already
3747 located the source file by its full name.
3749 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3750 find_pc_psymtab. When a name is found in the misc function
3751 vector, search the symbol table for its mangled name, not the
3752 name that the user typed.
3754 * bfd.h: Fix missing comment terminators, make #endifs match.
3756 * valarith.c (value_less): Handle unsigned int comparisons.
3757 Add FIXME about pointer compares, which assume host and target
3758 pointers are the same.
3760 * command.c (do_nothing_command): lint
3761 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3762 fix comments on debug symbol format for visibility. Actually set
3763 visibility of symbols.
3764 main.c (echo_command): lint; use <readline/history.h>.
3765 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3766 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3767 pointing past end of allocated memory; saber complains.
3768 obstack.h: Declare the external functions that we use.
3769 valarith.h: use <string.h>
3770 solib.c (solib_add): lint.
3772 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3774 * main.c (initialize_main): Default info_verbose to off, now that
3775 symbol reading is fast.
3776 (quit_command): Avoid clobbering exec_bfd while quitting.
3778 * Initial BFD (binary file diddling library) merger:
3779 coffread.c: Change AOUTHDR to struct exe_hdr.
3781 core.c: initialize initialized data at compile time.
3782 (core_file_command): Move from coredep.c, convert to bfd.
3783 (xfer_core_file): Convert to bfd.
3784 exec.c (exec_file_command): use bfd routines.
3786 mips-tdep.c: Remove exec_file_command and friends.
3789 * coredep.c: (fetch_core_registers) Convert core_file_command to
3790 fetch_core_registers.
3791 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3793 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3794 (my_bfd_read): More bogosity, which I don't think we call.
3795 (program_name): Remove this atrocity asap!
3797 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3800 values.c: allocate_repeat_value was not clearing the
3801 optimized_out field.
3802 (value_static_field): minor stylistic fix (wrong macro was used).
3803 valops.c (value_struct_elt_for_address): didn't work for C++
3806 * signame.c (_initialize_signame): Initialize signal names once.
3808 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3809 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3810 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3812 * remote-eb.c: Support user-settable baud rates on the serial port.
3814 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3816 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3818 * tconfig/sun3os4: Remove warning about native assembler,
3819 since it also occurs in the xconfig file.
3821 * findvar.c (registers): Allocate some slop after `registers'
3822 to prevent stray accesses from trashing the next variable.
3824 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3825 on the sun-3, by changing the #ifdef from `sun3' (which is not
3826 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3827 vars, which happened to follow `registers' in the executable.
3829 * readline/history.c (history_search): Heed gcc-2's advice
3830 and parenthesize && inside ||).
3832 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3833 tm-29k.c: Insert FSF copyright headers.
3835 * remote-eb.c: Better comments.
3837 * Makefile.dist: Update to 3.91.6.
3838 * TODO: note PREPARE_TO_STORE problem.
3840 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3842 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3844 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3846 * infrun.c (wait_for_inferior, at end): Don't set up
3847 prev_* if the inferior no longer exists.
3849 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3850 CANNOT_EXECUTE_STACK.
3851 valops.c (call_function): Use it.
3853 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3855 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3856 infrun.c (wait_for_inferior, 2 places): Use it.
3858 * values.c (value_being_returned): Only use
3859 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3861 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3862 right thing for remote-eb.c.
3864 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3865 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3867 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3868 (FRAME_FIND_SAVED_REGS).
3870 * findvar.c ({fetch,store}_registers): Check for
3871 REMOTE_{FETCH_STORE}_REGISTER macro.
3873 * findvar.c (get_saved_register): Add argument lval and
3874 change meaning of argument addr.
3875 findvar.c: Change calls to get_saved_register to reflect
3876 new calling convention.
3877 valops.c (value_assign): Use get_saved_register instead of
3878 find_saved_register.
3880 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3882 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3883 an (uninitialized) pointer to one. Use "&" when passing it
3886 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3888 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3891 * coffread.c (symbol_file_command): Put semicolon after
3893 Put safe_to_init_tdesc_context in #if defined (TDESC).
3894 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3895 coffread.c: #include <sys/stat.h>.
3896 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3897 Add missing ')' in check for "lc%" and friends. Remove
3899 Declare read_one_sym() at top of file.
3900 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3901 MC68WRMAGIC can have the same value without causing a duplicate
3904 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3906 * Allow a Makefile to be built without building the
3907 tm and xm file links that screw up builds in subdirectories.
3908 This is done with `config.gdb none', then you can do things
3909 like `make gdb.tar.Z'.
3910 * tconfig/none: Config file for no target system
3911 * xconfig/none: Config file for no host system
3912 * config.gdb: If no TM or XM files are called out by the
3913 host or target file, don't make links for them.
3915 * cplus-dem.c: Add documentation.
3917 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3918 simple error, so the user's gdb doesn't crash due to some object
3919 file problem (e.g. somebody is rebuilding the file out from under
3922 * printcmd.c (print_address_symbolic): demangle the symbol.
3924 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3925 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3926 (alldeps.mak): sort and uniq all results from this; duplicates
3927 hose gdb.tar.Z link building. Remove RCS files from
3928 tconfig and xconfig. Add config files for sun386. Add
3929 a few odd files to OTHERS and HFILES.
3931 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3933 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3934 Roll version number to 3.91.5. Make lint work in bindir.
3936 * README: Document cross-debugging and new file structure.
3938 * blockframe.c: Lint. Include "value.h" to declare read_register.
3939 (find_pc_partial_function): remove duplicate line.
3941 * command.h: Lint. Declare error_no_arg and dont_repeat.
3943 * tm-news.h: Remove inadvertently duplicated stuff.
3945 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3946 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3948 * config.gdb: Allow `config.gdb host target' form. Clean
3949 up previous change that printed bogus messages when you just said
3952 * core.c: #include "command.h" for lint.
3955 * main.c: Remove some casts of enums. Lint.
3962 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3964 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3965 read it from memory. This will allow us to save ptrace calls
3966 eventually. Changed caller single_step too.
3968 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3969 that we aren't going to use, saving many ptrace calls, especially
3970 when watchpointing or single stepping. Use some #define's for
3972 (store_inferior_registers): Ditto.
3973 (core_file_command): Use some #define's for constants.
3975 * tm-sparc.h: Add #define's for some register numbers, so we
3976 can eliminate the use of random constants in sparc-xdep.c.
3978 * stack.c (frame_command, print_frame_info, up_command,
3979 down_command) Remove frame_changed, since it
3980 causes a bug and doesn't seem to do anything useful. In some
3981 places it was used as a flag, in others as a stack level (?).
3983 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3984 default is to use the portable (vprintf) version rather than the
3986 * xm-news.h (MISSING_VPRINTF): Add.
3988 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3990 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3992 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3993 about linking debugged programs -Bstatic in the sun?os4 config
3994 files in tconfig and xconfig subdirectories.
3996 * main.c (main): Remove unreached exit(0) now that we exit
3999 * Create TODO file for online bug list. There are too many
4000 "little" bugs to keep track of on paper.
4002 * Change Projects file to refer to bug-gdb@cygnus.com
4003 rather than kingdon@ai.
4005 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
4007 * Makefile.dist (VERSION): 3.91.4 now.
4009 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
4010 (condense_misc_bunches): Add sanity check that misc_count is
4011 the same as the number of symbols in the bunch.
4013 * coffread.c: rename init_misc_bunches. Pass an argument
4014 to condense_misc_bunches (a zero).
4016 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
4017 every time we are called; don't rely on our caller to do it.
4018 (add_file): Remove call to init_misc_bunches.
4020 * mipsread.c: Only warn, don't error, if unknown symbol types.
4021 This keeps an old gdb from falling on its face if it sees newly
4022 extended symbol info. Rename init_misc_bunches.
4024 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
4026 * Merge in changes from Per Bothner for DECstations and other
4027 MIPS stuff. The rest is Bothner speaking:
4029 The next message is a merger of Alessando Forin's mips port with
4030 mine. I've tried to use my good if biased judgment to get
4031 the best of both. It *does* need testing.
4033 Some of the changes are general, *not* mips-specific.
4036 Didn't believe in little-endian bit order.
4037 There are still inconsistencies about whether flags
4038 like BITS_BIG_ENDIAN are integer (#if ...) or
4039 boolean (#ifdef ...). I tried to paper over them.
4041 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
4042 Moved some misc_function code that was common to
4043 {dbx,coff,mips}read.c to symtab.c.
4044 In the process, I think I cleaned things up a bit.
4045 At the same time, moved obsavestring and obconcat to symtab.c.
4048 Removed obsolete condense_addl_misc_bunches (use
4049 condense_misc_bunches(1) instead).
4052 Needed to include <sys/dir>, at least on DECstations.
4054 valops.c, mips-tdep.c, tm-mips.h:
4055 Added PUSH_ARGUMENTS macro to support funny argument-pushing
4056 conventions (when STACK_ALIGN is insufficient).
4057 Needed on mips, where doubles need 8-byte alignment,
4058 but ints only need 4.
4061 Removed cruft that was not being used.
4062 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
4065 Print $ before register-names (I think that makes things a little
4067 Never print two instructions, even if one delays.
4068 Removed hex-disassemble set_cmd. (This is not mips-specific,
4069 so I think the argument is whether it is generally worthwhile or not.
4070 I'm inclined to think not, given how easy it is to
4071 convert between radixes in gdb.)
4074 This is basically Alessando's code.
4075 It doesn't use obstacks; I changed it to use obstacks
4076 in a few minor places where using malloc causes a
4077 memory leak. (Probably, more places could/should be changed.)
4078 I added record_misc_function where it was missing.
4079 In symbol_file_command and add_file_command, I tried
4080 to make the code consistent with more recent versions.
4081 Minor sylistic changes in parse_procedure.
4082 Make a .gdbinfo. psuedo-symbol point back to the real
4083 procedure symbol (using the isym field).
4086 This is basically from my port, but with a lot of details
4087 and a number of routines merged in from Alessando's version.
4088 I basically used my code "raw" backtrace (use heuristics
4089 from the actual code, rather than symbol table info) - though
4090 the idea is Alessandro's. I feel my code is a little cleaner
4091 here, particularly in being a little more flexible, such as being
4092 able to handle gcc-produced code (which it now can).
4093 It also doesn't do frame caching (which is not useful
4094 more recent gdb versions).
4095 I also used my code for push_/pop_dummy, more or less.
4096 I tried to incorporate AF's code for testing sigtramp
4097 while backtracing; I probably got it wrong.
4098 Added mips_print_register, which tries to scrunch as much
4099 information as possible on a screen...
4100 Removed the skip-prologue set_cmd. As with hex-disassemble (see
4101 under mips-pinsn.c), I don't see anything mips-specific here,
4102 and I don't see it being all that useful anyway.
4105 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
4106 Use more register names (rather than hard-cases numbers).
4108 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
4110 * Hack up 3.90.11 changes:
4112 * Makefile.dist (depend): parameterize $(GCC).
4113 Add solib.c and solib.o.
4114 (readline): Fix vpath for both absolute or relative SRCDIR.
4116 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
4117 Also, let the part I didn't understand at least compile so
4118 I can test the rest. FIXME.
4120 * dbxread.c: Fix thinko using strcmp.
4121 (init_psymbol_list): declare static.
4122 (partial_symbol_file_open): Comment cleanups better, avoid
4123 cleaning up the string table since the caller will do that.
4124 Move the stat for mod time into symbol_file_command, temporarily.
4125 (There should be a mod time for each symbol file, eventually,
4126 to control its rereading. FIXME.)
4128 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
4129 SunOS, which gives error for shared libs otherwise. (From
4130 Schaefer, probably FIXME needs work for portability.)
4132 * solib.c: Move #include "param.h" to work.
4133 Lowercase all the Uppercase Letters In the Messages.
4134 (find_solib): Clean up inferior_so_name for debug printouts.
4135 Allow no argument, to mean all shared libraries.
4137 * symmisc.c: include param.h to get CLEAR_SOLIB.
4139 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
4141 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
4142 to 3.90.11. ChangeLog entries below are from this.
4144 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4148 * Makefile.dist (HFILES): Add tm-sunos.h.
4150 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4154 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
4156 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
4158 * sparc-opcode.h Added single-operand version of rett.
4160 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4162 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
4163 Put parens around gcc_p in expansion.
4165 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4167 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
4169 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4171 * Changes for Sun shared libraries:
4172 blockframe.c (find_pc_partial_function): If a non-text symbol
4173 is found, set *address = pc - FUNCTION_START_OFFSET.
4174 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
4175 Disable breakpoints instead of giving an error.
4176 source.c (select_source_symtab): Initialize cs_pst.
4177 symmisc.c: Call CLEAR_SOLIB if defined.
4178 symtab.h: Make text{low,high} CORE_ADDR not int.
4179 (psymtab): New field addr.
4181 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
4182 (record_misc_function): Give correct type for N_DATA symbols.
4183 (condense_misc_bunches): do "misc_function_count = j" regardless
4185 Take code which is shared between symbol_file_command and
4186 add_file_command and put it into partial_symbol_file_{open,read}.
4187 Split add_file_command into add_file_command and add_file.
4188 Make psymtab_to_symtab read in the string table if the file
4190 Two new parameters to read_dbx_symtab and start_psymtab.
4191 tm-sunos.h: New file.
4193 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4195 * infcmd.c: Change cont_command to continue_command and "cont"
4198 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4200 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
4202 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
4204 * values.c (USE_STRUCT_CONVENTION): Check for structures of
4205 size 1,2,4,8 rather than size < 8.
4207 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
4208 as necessary, not just once.
4210 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
4212 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4214 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
4216 * tm-news.h: Add CALL_DUMMY_*.
4218 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
4220 * config.gdb: In list_host, list_target, use ${i}, not $i.
4222 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4224 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
4226 * sparc-opcode.h: Change all store floating-point state register
4227 instructions to have the right match & lose fields.
4229 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4231 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
4233 config.gdb: If srcdir != ., create readline directory and
4234 copy a makefile into it.
4236 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
4237 consistency with POSIX.
4239 * breakpoint.c (bpstat_stop_status): Disable watchpoint
4240 when we exit its exp_valid_block.
4242 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
4244 * Makefile.dist: Bump version to 3.91.3.
4246 * Clean up handling of breakpoint commands (somewhat).
4247 Prompted by Tiemann bug report "cont 10" doesn't work any more.
4249 inferior.h: Add breakpoint_proceeded to inferior status struct
4250 and globals; save it and restore it.
4251 (clear_breakpoint_commands): Cleanup, remove old #define.
4253 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
4254 (save_inferior_status, restore_inferior_status): handle it also.
4255 (proceed): Remove earlier code that set breakpoint_proceeded.
4256 It is now set only in clear_proceed_status.
4257 (clear_proceed_status): Cleanup, use bpstat_clear rather
4258 than clear_breakpoint_commands. No callers need the stop_bpstat
4259 between clear_proceed_status and proceed.
4261 infcmd.c: Add breakpoint_proceeded definition and comment.
4262 (cont_command, jump_command, signal_command): Move call to
4263 clear_proceed_status right next to call to proceed.
4265 breakpoint.c (bpstat_do_actions): Avoid clobbering our
4266 caller's argument while running down the chain of breakpoints.
4267 Use new variable "breakpoint_proceeded" to determine when
4268 a command that it executes moves the inferior past the
4270 (bpstat_clear): Handle NULL argument.
4271 (bpstat_clear_actions): Avoid useless call to
4272 breakpoint_auto_delete.
4273 (delete_breakpoint): Clean up bpstat's that are pointing to
4274 the deleted breakpoint from the stop_bpstat chain.
4275 (breakpoint_auto_delete): Simplify.
4277 * Clean up handling of EOF, error on stdin, etc. This was
4278 prompted by a network problem that caused gdb to go into an
4279 infinite loop filling up its malloc'd memory.
4281 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
4282 not clear_breakpoints_commands, which is now gone.
4283 (main): If command_loop returns (e.g. from EOF on stdin), do
4284 a quit_command (looping back to command_loop if quit_command
4285 doesn't really quit).
4286 (command_loop): check result from command_line_input and
4287 exit if it returns NULL, rather than passing the NULL to
4289 (gdb_readline): Free malloc'd result space before returning
4292 * utils.c (query): Handle C-d to mean "yes", just as if the
4293 input was not a terminal. Also avoid infinite loop if EOF
4294 occurs in mid-input-line before newline. This allows
4295 query to be used at EOF on stdin with reasonable results.
4297 * infrun.c (proceed): Set breakpoint_proceeded.
4299 * values.c (value_as_long): Avoid infinite recursion for enums.
4300 (_initialize_values): Fix typo in help msg (kingdon).
4302 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
4303 RL_LIB for linking. This allows -lreadline for linking
4304 and nothing for dependencies, once readline is a real library.
4306 * config.gdb: Jim Kingdon: give useful error message if the
4307 host or target type is not recognized.
4309 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
4310 it just defines it. Dumb, but deal with it.
4312 * Jim Kingdon suggests:
4313 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
4315 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
4317 * Makefile.dist (VERSION): Bump version # to 3.91.2.
4319 * Clean up Bothner's changes.
4321 * blockframe.c (clear_pc_function_cache): New function.
4322 * blockframe.c: remake cache_pc_function_* static.
4323 * dbxread.c (symbol_file_command): remove references to
4324 cache_pc_function_* variables.
4325 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
4326 * printcmd.c: Avoid kludging a global variable (addressprint)
4327 to avoid printing the address of a string twice. Instead,
4328 pass the format letter 's' down low enough that it can be seen
4329 to avoid this problem.
4330 (print_formatted): Pass format arg to value_print.
4331 (restore_addressprint): Remove function.
4332 (do_examine): Avoid hacking addressprint, cleanups and such.
4333 (print_frame_args): Add a comment to a Bothner change.
4334 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
4335 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
4336 to wipe out the values cached in blockframe.c.
4337 * symtab.c (find_method): Add comment saying how big you must
4338 allocate to be "big enough". Per being terse again.
4339 * valprint.c (val_print): Handle format letter "s" to print
4340 strings without addresses. Add comment to vtbl printing code
4341 which casts with wild abandon. Rearrange reference-printing
4343 @0xaddr: value (print w/addressprint)
4344 value (print w/~addressprint)
4345 @0xaddr (parameter lists w/addressprint)
4346 or nothing (parameter lists w/o addressprint)
4348 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
4350 * Merge more changes from Per Bothner:
4352 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
4353 annoying) that I tried to improve it. Here are my suggestions.
4355 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
4358 Do automatic de-reference when taking the address of a reference.
4360 Don't deref_ref when printing parameter lists.
4362 More attempts at treating refernences properly.
4364 In val_print, if deref_ref==0, don't print dangling " = ".
4366 Add COERCE_REF macro, which de-references an REF.
4368 * Merge changes from Per Bothner:
4370 * Fixed (Sony news)-specific configuration problems.
4371 * Fixed other problems with using vanilla pcc and libc (enum problems;
4372 assumption that vsprintf exists).
4373 * Some major speed-ups (finc_pc_partial_function now caches a match;
4374 parsing avoids duplicate symbol_lookup calls).
4375 * Changed handling of baseclasses (no longer use baseclasses field
4376 of struct type, use the first n_baseclasses fields instead).
4377 * Various minor changes/fixes, most C++-related.
4380 Cache the most previous match from find_pc_partial_function.
4381 (Save both low and high ends of matching function's pc range.)
4382 This speeds up the loop of infrun.c:wait_for_inferior quite
4383 a bit, and makes step/next commands much zippier.
4385 Added an enum->int cast (otherwise, some compilers barf).
4387 No longer set baseclass offset to 0, since multiple
4388 inheritance now mostly works.
4389 Added a number of casts, to shut up compiler warnings
4390 (after stabs where made enums, not ints).
4391 When discarding a symbol table (in symbol_file_command),
4392 must clear the cache introduced in blockframe.c.
4393 Don't convert $vtbl_ptr_type to vtbl any more.
4394 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
4395 Mask off sign bit emitted by g++ for virtual table offset.
4396 Set voffset to -1 (not 1) for static member functions.
4398 Changed parsing/lexing of names to avoid doing symbol lookup twice
4399 (once when lexing to determine symbol class, once for real).
4400 Now only call symbol_lookup once. Fields of 'this' win especially big.
4402 Subpress printing addr twice in the case of 'x/s addr'.
4404 lookup_basetype_type is no longer used.
4405 Add find_methods as recursive helper function to decode_line_1.
4406 This allows multiple inheritance to work.
4407 Also, once one or more matches has been found, do not look in
4408 base-classes. (Baseclass methods would be overridden, anyway.)
4410 Removed baseclasses array in struct type.
4411 Instead of using baseclasses[i], use fields[i-1].
4412 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
4413 Changed sign convention of voffset (previous was inconsistent).
4415 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4417 Used to assume existence of vsprintf. Re-written to not need it
4418 if HAVE_VPRINTF is undefined.
4420 typecmp was too pessimistic. Made it less so.
4422 Don't print space after address.
4423 If vtable points to a misc symbol (with 0 offset), print it,
4424 since that indicates the actual class of the object.
4425 Changed ype_print_derivation_info to use new inheritance
4426 scheme (without baseclasses vector).
4428 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4429 Also, changes needed because TYPE_BASECLASSES were removed.
4431 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4433 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4436 If there is no path set, and the symbols don't indicate what directory
4437 a file was compiled in, look in the current directory. But either
4438 a path or a known compilation directory will prevent this.
4441 Three independent bug fixes:
4442 * Remove the #if 0 block that breaks some stuff.
4443 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4444 adapt gdb to either SunOS 4.0.* or 4.1.
4445 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4448 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4451 (type_print) Demangle the name being printed.
4452 (type_print_base) Handle botched demangling without coredump (tiemann).
4455 (check_stub_method): Document routine.
4456 (tiemann) fix bug for no-arg functions
4457 Avoid clobbering beyond end of malloc'd storage.
4458 Terminate the argument list properly.
4460 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4462 * Changes merged by John Gilmore:
4465 In breakpoint_1, use new print_address_symbolic instead
4466 of find_pc_partial_function. (This forces use of assembler-level
4467 addresses, and avoids misleading non-mangled source-level names.)
4469 Generalize ansi argument such that -1 means skip arglist totally.
4470 Removed global variable print_ansi_qualifiers (which made
4471 code non-reentrant), in favor of extra explicit arguments
4472 to internal routines.
4474 Add new helper function print_address_symbolic.
4475 Use find_pc_misc_function instead of find_pc_partial_function
4476 (since we want assembler-level symbols here).
4478 Print unknown function as just "f (...)", not "f (...) (...)".
4479 Use new fputs_demangled explicitly.
4481 Fixed a typing violation (problem: value.h cannot be imported
4482 without renaming many variable in this file).
4483 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4484 decode_line_1: Moved forward some never-reached code.
4485 Made decode_line_2 skip function prologues correctly.
4487 fputs_filtered should not demangle by default.
4488 Add new fputs_demangled to demangle on demand..
4490 Change value_struct_elt to use value_primitive_field (using recursive
4491 utility function search_struct_field). This allows foo.bar to work
4492 for multiple inheritance (so far only for data fields).
4493 Change check_field in the same way (recursive helper function
4494 to support multiple inheritance).
4495 (Note: there are more of these problems that I haven't fixed.
4496 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4497 value_of_this: 'this' symbol name is now just "this", note "$this".
4499 Don't print static members.
4500 Avoid printing "members of <type>" if there are none.
4501 Simplified type_print_derivation_info by merging duplicate code.
4502 Remove useless blank lines in type_print_base (ptype command).
4504 Added declaration of new routine value_primitive_field.
4506 Added value_primitive_field which is generalized version of
4507 value_field that can handle multiple inheritance (non-zero offsets etc).
4508 Re-implemented value_field to call value_primitive_field.

4512 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4513 delete the whole environment. Karl Berry reported the bug.
4514 * source.c - fix openp to avoid //'s in filenames, which
4515 trigger an Emacs bug causing it to not be able to find files
4516 when running gdb in a window.
4517 * dbxread.c - zap the #if 0 that botches the add-file code.

4541 format controls easier
4542 * wait.h added a couple of undef's because we were getting
4543 complaints about WSTOPSIG and WTERMSIG begin redefined.
