3 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
5 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
6 Pass MUNCH_DEFINE to munch whenever we run it.
7 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
8 format string; use 0x%x instead.
9 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
10 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
11 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
12 * inflow.c: Handle `short' process group IDs.
13 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
14 and check for ptrace errors.
15 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
16 (coff_symfile_init): Initialize text_bfd_scnum.
17 (read_coff_symtab): Use it to find the text [and absolute?] sections.
18 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
19 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
20 Merge target arm case with other "easy" cases. Add target
21 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
22 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
24 * minimon.h, remote-adapt.c, remote-mm.c: Add.
25 * munch: Cope with RT/PC putting fns in data segment.
26 Restore ability to override `nm' by specifying MUNCH_NM.
27 * xconfig/rtbsd, xconfig/ultra3: New host systems.
28 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
29 and remote-adapt. Remove encapsulated coff #define's (the
30 support should go in BFD, and gdb shouldn't know or care).
31 * tconfig/a29k-kern: Same, but for remote kernel debugging.
32 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
33 * tm-29k.h: Update BADMAG (though it should go away).
34 Allow the register definitions to be overridden in another
35 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
36 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
37 DUMMY_SAVE_GR96, for handling kernel calling conventions
38 that use GR64+ rather than GR96+.
39 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
40 remote debugging of Ultra3 kernel. Includes tm-29k.h and
41 overrides various things.
43 * remote-mm.c (mm_attach, mm_wait): Handle attach like
44 child_attach does, making a clean stop in the newly attached
48 * coffread.c: Make coffread independent of any particular
49 variant of COFF. Avoid #include-ing any particular one except
50 internalcoff.h. BFD now passes key values for symbol reading
51 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
52 and the symbol masks and shifts); use them.
53 Remove obsolete end_of_text_addr.
55 * exec.c: Remove unused include files.
57 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
59 * Makefile.in (documentation targets): Pass $(M4).
60 Bugfix from eggert@twinsun.com (Paul Eggert).
62 * stack.c (down_silently_command): Check for stack existence.
64 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
66 * Makefile.in (VERSION): Update to 4.0.3.
68 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
70 * core.c (core_file_command): Print frame at coredump with
71 its level number, by calling print_stack_frame.
72 * frame.h: Add selected_frame_level, print_stack_frame.
73 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
74 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
75 Change print_sel_frame and print_selected_frame callers to
78 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
79 * symfile.c (free_named_symtabs): Ditto.
80 * main.c (main): wrap_here needs an arg.
81 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
82 (solib_add): Avoid noise.
83 (solib_create_inferior_hook): Lint.
84 (sharedlibrary_command): Move dont_repeat to here.
85 * utils.c (error): Call wrap_here to force buffered output.
87 Small patches from Peter Schauer:
89 * coffread.c (start_symtab): Free any existing line_vector before
91 (read_coff_symtab): Ditto for type_vector.
93 * source.c (lines_to_list): New variable, replacing function.
94 (all uses): Use as variable.
95 (_initialize_source): Add 'set listsize' and 'show listsize'.
96 * utils.c (lines_to_list): Remove function.
97 * stack.c (print_frame_info): Use as variable.
98 * defs.h (lines_to_list): Remove declaration.
100 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
102 * breakpoint.c (insert_breakpoints): Restore warning about
103 the program might be running in another process, but only for
104 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
105 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
107 * utils.c (error): if error_pre_print is set, print the string
109 * main.c (main, print_gnu_advertisement, print_gdb_version):
110 Reformat legalese so it always prints, but acts as an "I'm here"
111 message while symbols are being read. If any errors occur,
112 print a few newlines to set off the message and start it at the
113 left margin. Remove mention of "help" command, and don't yak
114 about symbol reading.
115 (catch_errors): Error string is now printed first in case of
117 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
118 suggest the "help" command.
120 * Makefile.in (VERSION): Set to 4.0.2.
122 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
124 * .gdbinit: Remove useless "rr" command. Set complaints
125 to 1 for people debugging gdb.
127 * breakpoint.c, remote-vx.c: Reword strings printed by
128 catch_errors callers.
130 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
132 * WHATS.NEW: "history write -> history save". Doc "write on/off".
133 (Fix from kenc@viewlogic.com.)
135 Fix some infrastructure to be able to cope with host and target
136 machines with different sized basic types (ints, ptrs, etc).
137 (Idea from pierre@la.tce.com (Pierre Willard).)
139 * values.c (value_from_longest): Rename from value_from_long.
140 Handle pointer types as well as integers, so that targets with
141 different pointer sizes from the host can be accomodated.
142 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
143 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
144 uses of value_from_long to value_from_longest.
145 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
146 the correct pointer type to value_from_long{est}.
148 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
150 * remote-vx.c: Remove obsolete code for calling functions via
151 vxworks kludge interface (it referenced value_from_long).
153 * valops.c (value_string): Find malloc with lookup_misc_func, not
156 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
158 Make writing to files work properly. (Fixes to BFD are also needed.)
160 * core.c (core_open): Open file ourselves, read or r/w, depending on
161 write_files. Use bfd_fdopenr.
162 * gdbcore.h (write_files): New variable.
163 * exec.c (write_files): Define variable, add set&show for it.
164 (exec_file_command): Use write_files to open for read or r/write.
166 Make shared library reading happen automatically. These changes
167 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
169 * inferior.h (stop_soon_quietly): Add to exported variables.
170 * infrun.c (child_create_inferior): call solib hook, if defined.
171 (child_attach): call solib hook, if defined.
172 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
173 (find_solib): Use lookup_misc_func rather than hand-rolled.
174 (symbol_add_stub): New stub for catch_errors.
175 (solib_add): Avoid output if !from_tty. Catch errors rather
176 than just calling symbol_file_add and bombing.
177 (solib_create_inferior_hook): Interface with the target process
178 to let it read and alloc shared libs, then figure out what it did.
180 * core.c (validate_files): Fix typo, soften warning.
181 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
183 * utils.c (fputs_demangled): Avoid duplicate printing if
184 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
186 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
187 (Fix from pierre@la.tce.com (Pierre Willard).)
189 * main.c (catch_errors): Change argument to a char * from an int,
190 since a char * can point to a struct full of glop, but an int
191 is not guaranteed to be able to hold a pointer.
192 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
193 breakpoint_re_set_one, breakpoint_re_set): Adapt.
194 * core.c (core_open, solib_add_stub): Adapt.
195 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
197 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
199 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
200 by adding .NOEXPORT target.
202 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
206 * Makefile.in (VERSION): Roll to 4.0.
207 (gdb.tar.Z): Make refcard.ps as well, for shipment.
209 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
211 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
214 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
217 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
219 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
220 reflect above name change
222 * WHATS.NEW: correct pointer to refcard.
224 * doc/gdb.texinfo: update New Features, Installing
226 * doc/gdbint.texinfo: add short description of configure +template
228 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
230 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
232 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
234 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
235 tar file, add dependencies for referenced doc files.
237 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
239 * coffread.c, symfile.c, stack.c: saberized.
241 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
243 * doc/refcard.tex: permuted Essential Commands sec
245 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
247 set/show symbol-reloading
248 default set complaints 0
250 RET-repeat disabled after prompted long displays
251 processID (attach) interpretation of 2nd GDB cmdline arg
253 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
255 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
256 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
257 breakpoint.c, main.c: lint.
259 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
261 Install new configuration scheme for GDB and friends.
263 * config.sub: Translate ordinary names to three-part names.
264 * configure: Use three-part names internally.
265 * configure.in: Translate three-part names to filenames.
267 * README, WHATS.NEW: Update for gdb-4.0.
268 * Makefile.in: Roll VERSION to 3.99.
270 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
272 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
273 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
274 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
275 to single structures rather than arrays; when passing
276 their address, use &. This avoids trouble with bdead compilers.
277 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
278 instead. This avoids portability headaches.
279 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
281 * source.c (open_source_file): Avoid ANSI const bdeath by
282 skipping declaration and then casting result value.
283 * tm-hp300bsd.h: Clarify comment.
284 * utils.c (strstr): Result is const char *; ANSI bdeath.
285 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
286 since system include file defines it differently from "defs.h",
287 though the two are equivalent for our purposes.
288 * tconfig/hp300bsd: Add m68k-tdep.o.
290 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
292 * tconfig/sun*4: Remove warnings about system assembler.
294 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
296 * mcheck.c: Avoid warning about undeclared abort fn.
297 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
298 it causes recursive calls to error() when used in cleanups.
299 To do so requires that we make it a function, so we do.
300 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
301 * utils.c (do_cleanups): Remove the current cleanup from the
302 chain *before* calling it, in case error() is called from it.
303 The result won't be pretty, but won't be an infinite loop either.
305 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
307 * dbxread.c (read_struct_type): Grok anon structs for C++.
308 (vb_name, vptr_name): Null terminate these strings.
310 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
312 Minor bug fixes from BSD Net2 gdb:
314 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
315 returns 0, there is no previous frame.
316 * breakpoint.c (commands_command): If !from_tty, don't call
317 input_from_terminal_p().
318 * dbxread.c (record_misc_function): Speed up slightly.
319 (compare_psymbols): Ditto.
320 * infcmd.c (do_registers_info): Take a second argument to
321 determine whether to print float registers. "info registers"
322 does not do so anymore. "info all-registers" does, now.
323 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
325 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
326 * inflow.c (initialize_inflow): Set tflags_ours correctly.
330 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
331 executing_breakpoint_commands if we are interrupted by error.
332 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
333 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
334 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
335 catch_errors() so we can setup the frame regardless of whether
336 the shared libs work.
337 * ieee-float.c (double_to_ieee_extended): Get exponent from
338 right place in little-endian systems. From John Carey.
340 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
342 * main.c: Remove unused terminating_signals and catch_termination().
343 (long_options): Terminate with a zero element.
344 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
345 (gdb_readline): Make call-compatible with readline.
346 (init_signals): Improve comments re vfork vs. signal.
348 * utils.c (prompt_for_continue): Use new gdb_readline().
349 If we prompt for continuation, we don't let CR repeat the previous
350 command, once we get back to a prompt. It's too easy to keep
351 hitting CR, expecting "--more--" prompts, and have some long
352 command start repeating on you.
354 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
356 * blockframe.c (frameless_look_for_prologue): Speed up by
357 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
358 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
359 Define two variants, one faster.
360 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
361 and return zero, rather than giving an error.
362 (setup_arbitrary_frame): Initialize the PC in the new frame.
363 (skip_prologue): Add a second arg saying whether we're just
364 checking for a frameless function or not.
366 * core.c (core_open, core_close, core_xfer_memory): Move
367 section table pointers and bfd* into the target_ops.
368 (core_open): Allow errors in shared lib reading, etc.
369 (core_files_info): Describe shared library sections.
371 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
372 exec_files_info, set_section_command): Move section table
373 pointers and bfd* into the target_ops.
374 (add_to_section_table): Add BFD to section table.
376 * target.c (target_xfer_memory, target_info): Pass target to
377 xfer_memory and target_info functions.
380 * gdbcore.h: Move struct section_table.
381 * target.h: New home of struct section_table.
383 * solib.c (solib_add): New argument is the target_ops whose
384 section list is to be added to, if any. Reallocate the
385 sections in that target to add any that come from shared libs.
386 (throughout) so_sections renamed to sections.
387 (solib_xfer_memory): Deleted.
388 * tm-sunos.h (SOLIB_ADD): Add target argument.
389 (SOLIB_XFER_MEMORY): Delete.
391 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
392 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
393 from target_ops. It's the same on all targets. Add two section
394 pointers to target_ops.
396 * stack.c (find_relative_frame): Dump ancient algorithm for
397 "down", just use handy "next" pointers.
398 (frame_command): Don't error if there is no stack; let user
401 * inflow.c (new_tty_prefork, new_tty): New prefork routine
402 modifies static state in the parent process; new_tty itself
403 runs in the child and modifies the child's file descriptors
404 to match the saved static state.
405 * infrun.c (child_create_inferior): Call new_tty_prefork,
408 * infptrace.c (child_xfer_memory): Add ignored target arg.
409 * remote-eb.c (eb_xfer_inferior_memory): ''
410 * remote-nindy.c (nindy_xfer_inferior_memory): ''
411 * remote-vx.c (vx_xfer_memory): ''
412 * remote.c (remote_xfer_memory): ''. Rename from
413 remote_xfer_inferior_memory.
415 * main.c (main): Only try to attach "corefile" argument if
416 it starts with a digit.
418 * symfile.c (symbol_reloading): New "set/show" variable.
419 (symbol_file_add): Shorten message about symbol reading.
420 (add_symbol_file_command): Merge with add_syms_addr_command,
421 since this should work on all targets now.
422 (stop_whining): Default to zero, to shut up complaints
423 about bad symbol tables on many systems.
424 (free_named_symtabs): Just exit unless symbol_reloading.
426 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
427 and add comment explaining shared library screw.
429 * source.c: #if defined => #ifdef.
431 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
433 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
435 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
437 * doc/rdl-apps.texinfo: provide default readline-appendix finder
438 (doc/Makefile knows how to make one for local config)
440 * Makefile.in: use doc/Makefile for doc targets
442 * doc/Makefile: GDB documentation now has its own Makefile
443 doc/refcard.tex: renamed from "gdbrc.tex"
444 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
445 doc/gdbint.texinfo: add markup in "Cleanups" chapter
448 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
450 * values.c (baseclass_addr): When reading target memory, use the
451 length of the basetype, not the upper type. We've only malloc'd
452 enough space for the basetype, leading to errors in free().
454 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
455 ends up as a function specially, since we know the actual type of
456 the pointed-to address. This (somewhat) fixes display of
457 expressions that include misc_function_vector names. Try `cond 1
458 !strcmp("a","b")' then `i b'.
460 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
461 The child can be proceeded from inside wait_for_inferior in
462 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
463 getting skipped in that case.
465 * expprint.c (print_subexp): Use filtered output, since the
466 subroutines we call use it, otherwise the output is horribly
467 mangled, since output of wrappable stuff comes out late.
469 * Makefile.in: Bump VERSION to 3.98.1
471 * infrun.c (child_create_process): Use execlp to find the
472 shell to exec our target program. This requires some fiddling
473 with `environ' since there is no execlpe().
475 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
477 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
478 Minor rearrangement of refcard permits two new make targets--
479 gdbrc.dvi DVI output for refcard, using CM fonts
480 gdbrc.ps PostScript refcard, using PS fonts
482 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
486 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
487 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
489 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
491 * doc/gdb.texinfo: last changes for release.
492 Minor typo and formatting fixes; incorporated most fixes remaining from
493 filed mail commenting on earlier drafts.
495 Added warnings: pipes don't work in run command;
496 conditions are converse of assertions;
497 step over fn without debug info goes to next fn;
498 vars may have "wrong" values near fn entrance, exit
500 Added example from Kingston on printing repeated nonadjacent values
502 Added explicit mention that in Emacs gdb mode C-c and C-z are like
503 shell mode for signals
505 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
506 doesn't sound so much like its parent "Stopping and Continuing"; also
507 moved entries on continue to top of section, so they don't get lost.
509 Improved installation directions in appendix, added manual formatting
512 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
514 * configure.in: Remove xm.h and tm.h even if we aren't linking
515 new ones, so "./configure sun4; ./configure none" does the right
516 thing. Assume that alldeps.mak and depend are already built in
517 srcdir, and avoid running "make" (particularly "make depend",
518 which involves "gcc") from inside configure. Build Makefile
519 directly rather than building Makefile.conf first.
520 * configure: Regenerate with above changes.
521 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
522 to 3.98. Revise gdb.tar.Z procedure to produce a file
523 called gdb-$(VERSION).tar.Z but which unpacks into a
524 directory called "gdb". Move non-source files out of
525 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
526 (depend): Don't try to do "gcc expread.y".
527 (expread.o): Update dependencies by hand.
529 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
532 Fixed a variety of small typos that prevented info from formatting
533 cleanly; altered too-long heading for GPL Appendix, as discussed
534 w/RMS; Changed date on cover to July 91.
536 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
539 (1) Applied some fixes due to comments from Larry Breed (easier ones
541 (2) Eliminated use of @footnote---had my doubts about it anyways, and
542 it's broken in latest texinfo
543 (3) Introduced *some* use of [] for optional arguments, where
544 explanation is not simpler by listing cmd w arg and cmd w/out arg
545 separately. Still not using @deffn.
546 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
547 couple of headings are too long. Need patches to texinfo or revision
550 * Partial update to README (which still needs work for this
551 release!): (1) use of configure corrected for new script,
552 (2) "make gdb.dvi" and "make gdb.info" mentioned.
554 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
556 * symtab.c (lookup_symbol): Don't complain right off about
557 no debug symbols; use the misc function vector first.
558 (list_symbols): Use misc function vector to find symbols
559 that don't have debug info, and print them.
560 (find_pc_symtab): Temporarily avoid fatal() when psymtab
561 PC range doesn't match symtab PC range, as it does on the
562 MIPS because our symtab reading isn't perfect.
564 * dbxread.c (dbx_symfile_read): Make warning about
565 "no debug symbols" slightly nicer.
567 * source.c (select_source_symtab): If "main" symbol exists,
568 but decode_line_spec can't find line info, don't just return
569 a zero; try other source symtabs or give an error.
571 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
572 their low addresses first, then rip through fixing high addrs.
574 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
576 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
578 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
580 * Minor, mostly mechanical, cleanup of doc subdir for clean
581 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
582 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
584 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
586 Mostly MIPS and general symbol-reading fixups.
588 * doc/gdbint.texinfo: Add documentation on symbol-reading
591 * mipsread.c: Remove kludges around #include "ecoff.h".
592 Remove redefinitions of a_magic, etc, no longer used.
593 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
594 Fix global overview comments to match symfile.c protocol.
595 (mipscoff_new_init): Eliminate cur_hdr if we have one.
596 (mipscoff_symfile_read): Eliminate unused code. Avoid
597 sorting all the symtabs, when all we have read here is psymtabs.
598 The symtabs are sorted as they are created anyway. Tell
599 condense_misc_bunches whether we're mainline.
600 (psymtab_to_symtab_1): Pass filename when recursing, to make
601 stack trace more informative.
602 (parse_partial_symbols): Assume cur_hdr as argument.
603 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
604 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
605 the TYPE_NAME of char *, since that's done in symfile.c.
606 (free_numargs, parse_symbol, add_symbol, add_block,
607 shrink_linetable): Declare these fns void.
608 (upgrade_type): Convert tree of if's to switch. Clean up
609 bogus "off == 0" handling with a complaint. Avoid setting
610 field bitpos and bitsize of array with lower and upper bounds.
611 Check specified bitsize of elements against their actual type's
612 bitsize, and complain if different. Complain about unknown
614 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
615 (psymtab_to_symtab_1): Print names of subsidiary files that
616 are being read in. FIXME, we read far too many files. This code
617 is not the problem, the problem is in parse_fdr where the psymtabs
619 (cross_ref): Result should indicate that we used one aux entry
620 normally, or two if we encountered a "next" entry. This used
621 to leave the caller pointing at the wrong aux entry.
622 (add_symbol): If overflowed cur_block, reallocate it larger,
623 chase all pointers to it, and complain(), rather than clobber memory.
624 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
625 (new_field): Only allocate one field initially, not two.
626 Pull ++ out of macro argument. Simplify.
627 (_initialize_mipsread): Avoid initialization of importd
628 global_psymbols and static_psymbols.
630 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
631 to properly set pst->symtab; avoid searching for it.
632 (symfile_fns): Improve comments, add a FIXME.
633 * dbxread.c: Update comments to reflect symfile protocol.
634 (read_ofile_symtab, end_symtab): Return the symtab.
635 (psymtab_to_symtab_1): Set pst->symtab.
637 * coffread.c (coff_symfile_read): tell condense_misc_bunches
638 whether we're mainline.
640 * symfile.h (sym_fns): Remove unused sym_discard member.
641 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
643 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
644 the environment variable is not.
645 * infcmd.c (finish_command): Use filtered printfs.
646 * cplus-dem.c: Add struct tags to a few unnamed structs.
647 * valops.c (value_coerce_array): Improve comments.
648 * valprint.c (type_print_varspec_suffix): Print array size only
649 if greater than zero.
650 * m88k-tdep.c: Shift some lines left by one space, that had
651 apparently been trashed at some point.
652 * TODO: More things to do, a few got done.
654 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
656 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
657 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
659 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
660 * expread.y, findvar.c, symmisc.c: Ditto.
661 * printcmd.c (address_info): Update printed forms of LOC_
662 symbols. Elim LOC_EXTERNAL.
663 (print_frame_args): Keep track of param stack offsets before
664 re-looking up to find the local register param is kept in.
666 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
667 Further integration of mipsread into gdb. Eliminate unused
668 routines, duplicate declarations. Handle static symbols in
669 psymtabs as well as external symbols. When reading symtabs,
670 insert symbols into the correct block (global, static, or a local
672 (read_mips_symtab, parse_partial_symbols): Don't pass useless
674 (mipscoff_symfile_read): Don't call select_source_symtab.
675 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
676 rather than SYMBOL_VALUE.
677 (parse_external): Comment clobbering of top_stack.
678 (parse_partial_symbols): Update comments. Allocate and parse
679 static symbols as well as external symbols. FIXME, enum values
680 are not handled in this pass, but should be. Inline new_psymbol.
681 Use SYMBOL_VALUE_ADDRESS.
682 (psymtab_to_symtab_1): Read symbols into global static block
683 by default (until enter some function's local block context).
684 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
685 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
687 * source.c (select_source_symtab): Select a source symtab
688 from either the symtabs or, failing that, the psymtabs.
689 (list_command): Update error message.
690 (forward_search_command, reverse_search_command): Use getc, not
691 fgetc, for speed. FIXME, add comment about buffers that die if
692 overrun by long line.
694 * values.c (unpack_field_as_long, modify_field): Avoid shifting
695 by an entire word, which is not portable, if we have a 32-bit
696 field. (Code in dbxread.c already turns such bitfields, if
697 aligned, into ordinary ints, but fixing this will help for other
698 symbol formats and for future changes.)
699 * core.c (core_open): Handle ANSI const brain death.
700 * utils.c (vprintf): Fix varargs typo.
702 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
704 * findvar.c (find_var_value): Handle &function better.
705 * TODO: Document work needed on &fn and &array.
706 * printcmd.c (print_address_symbolic): New arg is the prefix
707 to print if a name is printed.
708 (print_address_demangle): Honor "set print address" now.
709 Use new arg above to improve spacing of output.
710 * valprint.c (val_print): When printing function pointers,
711 print symbolic form too.
712 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
714 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
716 * core.c (memory_error): Reword error msg to mislead less.
718 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
720 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
721 parse_partial_symbols): Use newer BFD internals (external_filehdr
722 and external_aouthdr), byte-swap the fields that we care about
723 before using them, and make the file header data local to
724 read_the_mips_symtab rather than global.
726 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
728 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
729 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
731 * main.c (command_line_input): Flush stdout and stderr
732 before every call to readline. This reportedly fixes a bug
733 that comes up in Sys V running emacs-gdb and/or xxgdb,
734 when stdin/out are pipes or sockets.
736 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
738 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
739 Avoid declaring Makefile dependencies, because GNU Make stupidly
740 tries to update it if we do.
742 * coffread.c: Revise for minor changes to bfd internal coff
745 * configure: If -template= is given a relative path, make it
746 absolute before recurring in subdirectories.
748 * configure, configure.in, Makefile.in: Install "configure" script
749 as replacement for config.gdb.
750 * config.gdb, Makefile.dist, Makefile.sdir: Remove
751 * README: Update for configure, mostly. FIXME.
753 * Add dec3100 as equivalent to littlemips. Indicate in all host &
754 target config files that they are for the host. When the lines
755 get copied into the Makefile, this makes it more obvious what's
758 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
760 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
761 tabs, which end up in the disassembler output inadvertently.
763 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
765 Make it compile cleanly in an ANSI GCC2 environment.
767 * blockframe.c: <stdio.h>
768 * cplus-dem.c: free takes a void *, ifdef __STDC__
769 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
771 * defs.h (alloca): Avoid doing anything if alloca already def'd.
772 * stddef.h, stdlib.h: Remove these files.
773 * symtab.c: Avoid declaring qsort, close.
774 * symfile.c: Avoid declaring close.
775 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
776 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
778 Assorted other changes.
779 * dbxread.c: include "libaout.h", not "liba.out.h".
780 * printcmd.c (print_frame_args): Set recurse properly for
781 indentation of struct and array parameters.
782 * valops.c (value_cast): Allow cast to void.
783 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
784 single_step() in a target-independent fashion.
785 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
786 set up to be ready to continue. This makes us target independent.
787 * infptrace.c (child_resume): Remove call to single_step; now
788 can single step a SPARC target of any kind.
790 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
792 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
793 docn into separate sections---basically chapters, plus two loose
794 pieces that can be configured to go in different places. This
795 allows GNU m4 to preprocess the manual without coredumping.
797 * Makefile.dist: tell TeX where to find texinfo.
799 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
801 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
802 the new target "rdl-apps.texinfo" which captures the Makefile
803 variable that records where to find the Readline libraries.
805 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
807 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
808 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
809 * defs.h (const, volatile): Only define if not already defined.
810 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
812 * README: Update for release 3.95.
813 * config.gdb: Don't create readline dir in subdir builds.
814 * main.c: Include with "..." form for non-system include files,
815 so "gcc -MM" for "make depend" works.
816 Include readline files with "...h" rather than <readline/...h>.
817 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
819 * coffread.c: Undo minor damage done by Rich Pixley. Use
820 different internal and external representations of COFF
821 data structures. Use new BFD routines for swapping them in and
823 * symfile.c (free_named_symtabs): Avoid freeing file names that
824 are null or empty. Old i960 tools seem to produce files that
825 claim to have empty names, causing each successive file read
826 to blow away the previous one.
827 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
828 Move deferred_stores to top of file, but don't separate its
829 #define's from its variable. Add commentary.
830 * Makefile.dist: Fix Rich damage; undo "configure" changes in
831 favor of keeping the (working) config.gdb. Move readline
834 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
836 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
838 * infptrace.c (fetch_registers): no result, since now void.
839 * tconfig/news: target depends on m68k-tdep too.
841 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
843 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
846 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
847 applied various small fixes due to or inspired by RMS comments
849 * doc/gdb.texinfo: finished using all RMS comments, save those for
850 appendices on readline and cmd history (which are in other source
853 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
855 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
856 chapter 9; (2) documented 'break' command's menu mode for
857 overloaded names, in response to hgs problem report C++ p-31
859 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
861 * doc/gdb.texinfo: (1) better introductory example; (2) more
862 consistent use of @code, @samp, @file, @kbd throughout; small
863 cleanups to first three nodes; (3) new "Contributors" node;
864 (4) Appendix, Renamed Commands; (5) divert specialized startup
865 instructions to "Targets" chapter for generic manuals, while
866 leaving them up front for manuals specific to specialized
867 environments; (6) apply fixes from RMS comments through chapter 4.
869 * pretex.m4: modify explanatory text slightly (and redefine
870 "regexp") to keep GNU m4 from complaining. (It still crashes
871 later, but one step at a time...)
873 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
875 * readline/readline.c (update_line): Avoid dereferencing a pointer
876 before comparing it to its bounds. Saber caught this.
877 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
878 and only set PC if tgetstr returned non-null. Saber caught this.
880 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
882 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
883 stuff for config manual) here where it counts; updated
884 to use new subdir structure (gdb/doc/).
886 * Makefile: generated from above via
890 * gdbint.texinfo: added instructions on generating gdb.info* files
891 locally for release. These are ordinary info
892 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
893 Makefile)---but due to use of texinfo 2, can't count on makeinfo
894 to generate these, so we distribute them already formatted.
896 * gdb.texinfo: included full Info node and menu crud (as generated
897 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
899 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
900 put in comments-for-future gdb.info target (one day makeinfo will
903 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
905 * gdb.texinfo: Updated to include new or old undocumented
906 commands, at least the following (perhaps some others I forgot to
907 record): info f, info float, info path, info program, info s, info
908 set, info source, info terminal, info types, info user, set/show
910 Also covered all recent GDB command renames for v4.
912 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
914 * mipsread.c: Rather than keeping count of how many symtabs
915 and psymtabs we have, for sorting purposes, count them when
916 we need to sort. This fixes bug in rereading of symbol tables.
918 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
920 * infcmd.c: renamed "info path" to "show paths"
921 * gdbrc.tex: documented above.
923 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
925 * remote.c: Fix comments.
926 * utils.c (error): Force out any pending wrap output.
928 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
930 * Makefile.dist: Roll VERSION to 3.95.
931 Fix up "saber_gdb" to work again.
932 * saber.suppress: Update.
934 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
935 symtab.h, target.c, target.h: Lint.
936 * core.c: setup and select frame after reading shared libs,
937 else reading shared libs will clobber them. Lint.
938 * utils.c (error): Force out any buffered wrap text.
940 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
942 * remote.c: Remove decls of memory_insert_breakpoint
943 and memory_remove_breakpoint, no longer used. (Suggestion of
946 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
947 to make it easier to interface to "configure"'d libraries.
949 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
951 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
952 aliases for set/show print.
954 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
956 * coffread.c (coff_sym_fns) [TDESC]: Make the type be m88kbcs.
958 * m88k-tdep.c (IEEE_isNAN): New function.
960 * infrun.c, m88k-tdep.c, m88k-xdep.c: Change
961 initialize_{tdesc,dcontext} to init_{tdesc,dcontext}.
963 * infrun.c [TDESC]: Add a bunch of crud.
965 * xm-88k.h [__GNUC__]: Don't define memset.
967 * m88k-xdep.c: #if 0 out push_breakpoint.
969 * tm-88k.h: Define GET_SAVED_REGISTER.
971 * tm-88k.h: Define DGUX.
973 * m88k-opcode.h (UEXT, SEXT, MAKE): Put parentheses around arguments.
975 * m88k-pinsn.c (sprint_address): Declare at top of file.
977 * m88k-xdep.c: #if 0 out core_file_command.
979 * values.c ({unpack_,value_as_}pointer): Just call
980 {unpack_,value_as_}long (for now anyway).
982 * m88k-tdep.c (get_saved_register): Make get_reg a dc_word_t (*)().
983 (psr_register): Change return type to dc_word_t.
985 * m88k-tdep.c (tdesc_read_function): Comment out call to ptrace.
987 * m88k-tdep.c (get_saved_register): Add lvalp parameter.
989 * gdbcore.h (write_memory): Don't prototype it.
991 * tm-88k.h, m88k-tdep.c: Make stack_error, stack_jmp global.
992 m88k-xdep.c: Don't mention stack_error.
994 * {x,t}config/m88k ({X,T}DEPFILES): Add missing files.
996 * mtrace.c: Don't typedef things like size_t, just #define them.

1465 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
1466 Call target_preopen from open routine.
1468 * main.c: Rename editing_info to show_commands.
1469 (_initialize_main): Rename "info editing" to "show commands".
1471 * source.c: Rename directories_info to show_directories.
1472 (_initialize_values): Rename "info directories" to "show directories".
1474 * values.c: Rename convenience_info to show_convenience.
1475 (_initialize_values): Rename "info convenience" to "show convenience".
1477 * copying.awk (_initialize_copying): Rename "info copying" to
1478 "show copying" and "info warranty" to "show warranty".
1479 Rename {copying,warranty}_info to show_{copying,warranty}.
1481 * symfile.c: Rename add_syms_command to add_symbol_file_command.
1482 (_initialize_symfile, add_syms_addr_command):
1483 Rename add-syms to add-symbol-file.
1485 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
1487 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
1488 * symfile.c (clear_symtab_users_once, cashier_psymtab,
1489 free_named_symtabs): Move these routines from symmisc.c.
1490 * symmisc.c (same): same.
1491 (free_symtab): Make non-static.
1492 * symtab.h (free_symtab): Declare as exported void fn now.
1493 * dbxread.c (end_symtab, end_psymtab): Change comments.
1494 (initialize_dbxread): Call dbx_new_init() in case the first
1495 command is add-symbols.
1496 * target.c (dummy_target): Permit add_syms_addr_command.
1498 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1500 Permit symbols to be superseded when new symbol files have
1501 been read in, particularly for VxWorks.
1503 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
1504 to the main file, as well as to include files. Also, put global
1505 functions into the global psymtab, to make "i fun" work.
1506 (end_psymtab): Free named symtabs and psymtabs for a file, once a
1507 new psymtab for it has been read.
1508 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
1509 a file, once a new symtab has been read for it.
1510 * mipsread.c: FIXME. We need to do the same for MIPS, but it
1511 looks harder to determine the top-level block before it's been
1512 queued to the psymtab list.
1514 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
1515 If we have wiped out any old symbol tables, clean up at end of
1517 (symbol_file_command): Don't reference symfile_fns if it's zero.
1519 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
1520 defines for the blocks of a blockvector that contain global and
1521 file-static symbols and the first of the smaller scope contours.
1522 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
1523 decode_line_1, make_symbol_completion_list): Use the above.
1524 * coffread.c (end_symtab, patch_opaque_types): Ditto.
1525 * dbxread.c (end_symtab): Ditto.
1526 * expread.y (block): Ditto.
1527 * mipsread.c (throughout): Ditto.
1528 * symmisc.c (free_named_symtabs): Ditto.
1530 * symtab.c (list_symbols): Process the first symbol of the
1531 static psymbols list.
1532 (types_info): Restore this function from its untimely #if 0.
1533 It's not perfect, but it is better than nothing.
1534 (_initialize_symtab): Restore "info types".
1536 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1538 * m68k-stub.c: Remote stub for 680x0's, created from
1539 rem-m68k.shar (which is removed).
1540 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
1541 Remove RCS log stuff now that we use CVS and it blows our diffs.
1543 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1545 * symmisc.c (free_named_symtab): Make it work, in its current
1546 kludgy fashion. Change result to indicate if we blew away bkpts.
1547 * dbxread.c (end_symtab): Accumulate result from
1548 free_named_symtab and print warning if we blew user's state.
1549 * symfile.h: free_named_symtab now returns an int.
1551 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1553 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
1554 is the first symbol read, even if not mainline.
1555 (dbx_psymtab_to_symtab): symfile might be zero, cope.
1556 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1557 (set_section_command): New command ("section xxx yyy" -- should
1558 be renamed to "set section xxx yyy" FIXME) which sets the
1559 base address of a section of the exec file, overriding the
1560 virtual address that BFD reports.
1562 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1564 * exec.c: Add add_syms_addr_command to exec_ops, so you can
1565 load symbols at any address while examining an exec file.
1567 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1569 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1570 for printing the float info is host-dependent, not
1571 target-dependent. FIXME.
1572 * i386-pinsn.c: Move #includes to top, remove useless ones.
1573 * i386-tdep.c: Don't bother including <.../reg.h> since we
1574 don't use it (and it doesn't exist on host systems).
1576 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1577 Convert negative numbers properly.
1578 (ieee_test): Make numbers really random; fix format arg.
1580 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1581 * core.c (core_detach): Unpush core_ops, which might not be on
1582 top. We used to just pop the top, which broke things. Don't
1583 need dont_repeat() any more.
1584 (core_file_command): Psst! Don't repeat it.
1585 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1586 * expprint.c (print_subexp): Avoid switch fallthru on
1587 BINOP_ASSIGN_MODIFY, so we can print += and such.
1588 * frame.h: Fix typo.
1589 * inflow.c (kill_command): After killing inferior, print our
1590 current frame in the core file, if we have one.
1591 (generic_mourn_inferior): When inferior dies, either select
1592 the current frame (in the new target, e.g. core file), or
1593 set both the current and selected frames to NULL.
1595 Changes from Peter Schauer.
1597 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1599 * Make all file names fit in 14 characters (sigh and damn!):
1600 mv hp300hpux-xdep.c hp300ux-xdep.c
1601 mv symmetry-xdep.c symm-xdep.c
1602 mv symmetry-tdep.c symm-tdep.c
1603 mv convex-opcode.h convx-opcode.h
1604 mv tm-vxworks960.h tm-vx960.h
1605 mv tm-vxworks68.h tm-vx68.h
1606 mv Makefile.srcdir Makefile.sdir
1607 mv gdb-int.texinfo gdbint.texinfo
1608 mv remote-sa.m68k.shar rem-m68k.shar
1609 mv remote-multi.shar rem-multi.shar
1610 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1611 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1612 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1615 * command.c (user_info_1, user_info): New command for listing
1616 the user-defined commands.
1618 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1620 * dbxread.c (really_free_pendings): Clear file_symbols
1621 and global_symbols after freeing them; otherwise, running
1622 this function twice (if it appears twice on the cleanup
1623 chain), we try to free things twice.
1625 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1626 based on text_addr (the address of text in core), not on addr (the
1627 offset between text in the .o file and in core). This change
1628 is from Peter Schauer.
1630 * main.c: Define ALL_CLEANUPS as a cast of zero.
1631 (return_to_top_level): Use it.
1632 (main): Do all cleanups after each command run as part
1633 of the gdb startup sequence. Also do all cleanups before
1634 entering the command loop, and every time we exit the command
1635 loop and reenter. Before, the cleanups from the startup sequence
1636 were being left undone until the first error!
1637 (command_loop): Rename do_nothing cleanup to command_loop_marker
1638 so we can see it easily when examining the cleanup chain.
1639 (init_signals): Add another do_nothing for signal handling.
1640 (quit_command): Only try to kill target if it has execution.
1641 Problems in the target stack got us into a state where
1642 inferior_pid was nonzero but none of the targets had execution.
1643 In this state you couldn't exit gdb.
1645 * dbxread.c: Two changes from Peter Schauer.
1646 (echo_command): Fflush output after an echo command.
1647 (show_history): Pass all args to cmd_show_list.
1649 * utils.c (init_malloc): Call mtrace to turn on tracing
1650 if the environment variable MALLOC_TRACE is set to a file name.
1651 * mtrace.c: Add source file which provides a log of every malloc,
1652 free, and realloc to a trace file.
1653 * mtrace.awk: Add source file which analyzes the trace file.
1654 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1655 (VERSION): Roll to 3.94.3.
1657 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1658 (check_duplicates): Don't bother with watchpoints.
1659 (set_raw_breakpoint): Comment about danger of this routine.
1660 (watch_command): Parse and eval all args before calling
1663 * solib.c (find_solib): Avoid error in referencing memory to
1664 see if any more shared libraries have been added. This is
1665 particularly useful if the target has terminated. Bug reported
1668 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1669 in bringing up 3.94.2 on the Sun-3.
1671 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1672 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1673 expression (in scope) before reenabling watchpoint.
1674 * signame.c (init_sigs): Add missing declaration of i, fix
1675 sys_siglist declaration.
1676 * source.c (list_command): Fixed range computation to use
1678 * stack.c (backtrace_command): Do not allow command if target has
1679 no stack, print informative error message.
1680 * target.c (target_command): Do not write into command line
1681 because this fails if the target command is used in a user defined
1682 command. [This change was enhanced by gnu to support any-
1683 unique-prefix matching on target names.]
1684 * valops.c (value_struct_elt): Avoid infinite loop on an
1685 erroneous attempt to print the member of function (try p main.p).
1687 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1689 * expread.y (name_no_typename): Avoid reduce/reduce errors
1690 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1691 Since the GDB parser really doesn't use name_no_typename in a
1692 name-only context, the parser can't tell the diff between
1693 names and numbers here. Avoid allowing a name_no_typename
1694 to be a NAME_OR_*INT to resolve the conflict.
1696 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1698 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1700 * valprint.c (val_print_fields): bitfield printing didn't handle
1701 byte order. Indirect through a few more fns to cope.
1703 * values.c (modify_field): also cope with byte order.
1705 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1707 Cleanup for release 3.94.2:
1709 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1710 include files. Roll version to 3.94.2.
1712 * coffread.c (init_stringtab): Read length into unsigned char
1713 array before swapping; don't assume 32-bit longs.
1715 * target.c (target_info): Don't bother with get_sym_file, just use
1716 the symfile global variable.
1717 * symtab.h, symfile.c (get_sym_file): Delete it.
1719 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1720 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1721 (read_type): Replace one more error() with complain().
1723 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1725 * i960-tdep.c: Fix copyright attribution.
1727 * config.gdb: Quote all backquotes in doublequotes. You can
1728 quote me on that. BSD 4.4 shell found this one.
1730 * infptrace.c (throughout): The third argument to ptrace is an
1733 * infrun.c (wait_for_inferior): When program has terminated, we
1734 have to call target_terminal_ours before we pop that target off
1735 the stack (e.g. before a call to target_kill or
1736 target_mourn_inferior). This fixes problem where a program
1737 terminates, then GDB stops for (tty output) and you have to type
1738 "fg" to the shell to resume it. FIXME: This code for what to
1739 do after termination really should be in normal_stop instead.
1741 * gdbcore.h (read_memory_check): Change declaration; it changed
1744 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1745 4.4 prereleases, this avoids a bug in their sgtty compatability
1747 * remote.c: Use terminal.h rather than hand-rolling the same.
1749 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1750 * utils.c (strsave, strstr): Fix arg types.
1751 * valprint.c (val_print): lint
1753 MIPS symbol table support from Per Bothner:
1755 * symfile.c (symtab_fns): Remove initializer table that needs to
1756 be hacked for each new symbol file format supported.
1757 (add_symtab_fns): New function, chains symbol table
1758 handlers into the global list.
1759 (symfile_init): Search this list.
1760 * symfile.h: Add next pointer, declare add_symtab_fns.
1761 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1762 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1764 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1765 symbol *). Thus, we no longer need the hack to trash
1766 pst->filename. Good, since that hack confused code in symfile.c!
1768 (reorder_symtabs, destroy_all_symtabs): Removed static
1769 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1770 Instead, the latter now uses a temporary array (stack-allocated
1771 from an obstack, and then freed).
1773 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1774 haven't been set in the outermost stBlock of a procedure. This was
1775 a problem with f77 binaries on Ultrix 4.?.
1777 (new_symtab, new_symbol, new_type): Continue changing code to use
1778 obstacks more and otherwise conform to dbxread internal style.
1779 Made the free_code of symtabs be free_linetable (as in dbxread)
1780 instead of free_contents. This implies memory leaks when reading
1781 a new symbol table, until the conversion is finished. Did change
1782 (struct symbol) and (struct type) to be allocated on the
1783 symbol_obstack. Blocks and blockvectors are among the things
1786 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1787 tested much, but it solved one problem (reported by Meissner), and
1788 cleans up some other things. The problem happened when an
1789 included file contains actual code (functions) and not just
1790 definitions. The mips coff is a little inconvenient there, since
1791 it may cause a procedure to be mapped to the wrong psymtab.
1793 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1794 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1795 this will need work for the new core paradigm.
1797 Opcode patches from the net:
1799 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1800 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1801 missing altogether - they are added here. From Bruce Bauman.
1802 * mips-opcode.h: The low mask for C0 instructions was too small.
1803 From Garrett Lau. I modified the fix to check the entire 32-bit
1806 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1809 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1811 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1813 * dbxread.c (read_type): Pointer subtraction (value_sub in
1814 valarith.c) sometimes failed because the types of the
1815 pointers being subtracted were not identical.
1816 These differed because dbxread.c was allocating pointer types
1817 using dbx_alloc_type+smash_to_pointer_type instead of
1818 lookup_pointer_type. I failed to find a justification for the
1819 former, so I changed it to use the latter. Similarly, I
1820 replaced smash_to_function_type by lookup_function_type,
1821 and smash_to_reference_type by lookup_reference_type.
1823 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1824 _initialize_mipsread): corresponding changes.
1826 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1828 * source.c (mod_path): Do tilde_expand on each component of the path,
1829 rather than on the (list of) paths as a whole.
1830 (print_source_lines): Set first_line_listed in addition to
1831 current_source_symtab and current_source_line. If the source was
1832 not findable, after a "dir" command to fix the problem,
1833 a "list" would get the wrong lines.
1835 While I was there... (gnu):
1837 * dbxread.c (read_type): Change error to complaint.
1839 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1841 First attempt at detailed understanding of symbol table memory alloc.
1843 * dbxread.c (dbx_symfile_read): Free our string table if we
1844 aren't the mainline. Free the "info" struct since we're done with
1846 (init_psymbol_list): Free any previously allocated psymbol lists.
1847 (): FIXME: Should realloc-down the psymbol lists when done reading
1848 the main symbol file?
1850 * symmisc.c (free_symtab): Free fullname field too.
1852 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1853 (REGISTER_ADDR): Make result type unsigned int.
1855 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1856 define REGEX must also define REGEX1 (its dependency).
1858 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1860 * tconfig/i960: No longer works, points you at vxworks960 or
1863 * xgdb.c, XGDB-README: Remove file. Users can get the much
1865 * Makefile.dist: Remove all trace of xgdb.
1867 * breakpoint.c (breakpoint_1): Pass demangle arg to
1868 print_address_symbolic.
1869 (clear_breakpoints): Remove unused function.
1870 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1871 (breakpoint_re_set): Use catch_errors to do them all anyway.
1873 * gdb-int.texinfo (Host versus Target): Add section on what is
1874 a "host" feature versus what is a "target" feature.
1876 * infcmd.c (path_command, path_info): Handle the PATH variable
1877 (object search path) as conveniently as the source search path.
1878 * environ.c (set_in_environ): Set some vars in GDB's environment,
1879 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1880 * source.c (mod_path): New function, from guts of
1881 directory_command, modifies a path. Used by path_command.
1882 (directory_command): Call it.
1883 * defs.h (strsave): Declare.
1885 * utils.c (sevenbit_strings): Add new printing option.
1886 (printchar): Use it.
1887 (strsave): Provide this handy helper routine.
1888 (set_width_command): Rename set_screen_width_command.
1889 (_initialize_utils): "set screen-width" => "set width";
1890 "set screen-height" => "set height"; add sevenbit-strings.
1892 * infcmd.c (do_registers_info): Print floating point registers
1893 in raw hex as well as float format, regardless of whether it is
1894 a "virtual" convertible register.
1895 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1896 regs as a double, just in case it's being used that way.
1897 * values.c (unpack_long): Comment on array/function coercion.
1898 (unpack_double): Argument is in target byte order now. For
1899 integer arguments, just call unpack_long and float the result.
1900 * m68k-tdep.c: include defs.h for "const" handling.
1901 * remote-nindy.c: Use ieee-float stuff.
1902 (nindy_fetch_registers): Unpack double regs to host double, then
1904 (nindy_store_registers): Pack extendeds to host double, flip
1905 around by misusing unpack_double, send as target double.
1907 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1908 zero, as when stopped at the first instruction of a process.
1910 * blockframe.c: Fix filename in comment (param.h => tm.h).
1911 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1912 * tm-68k.h: Fix typos.
1914 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1916 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1918 * coredep.c (fetch_core_registers): Pass end-address of register
1919 section to register_addr as expected. Don't call supply_register
1920 if we'd just pass it garbage.
1922 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1924 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1926 * target.c (push_target, target_info): Cast enums to int for < or
1929 * stack.c (print_frame_info): Identify source file & line
1930 even if we can't print it.
1932 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1934 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)

1957 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1958 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1959 * tconfig/nindy960: Remove reference to coffstrip.o.
1961 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1963 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)

1969 * inftarg.c (child_detach): Pop the child_ops vector if the
1970 detach is successful.
1971 * remote-nindy.c (nindy_create_inferior): Don't push a new
1972 nindy_ops since nindy uses the same one for execution and memory
1974 * core.c (core_ops): Use child_attach and child_create_inferior
1975 rather than default attach and create_inferior functions.
1977 Handle floating point registers in core files.
1979 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1980 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1981 This version untested since BFD doesn't yet support sun3 core
1983 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1984 conventions. Fix comments and style. This version has not
1985 been compiled yet, since we have no HP inhouse.
1986 * core.c (get_core_registers): Look for two sections, ".reg"
1987 and ".reg2", and pass both to fetch_core_registers sequentially.
1989 Revise directory path yet again.
1991 * source.c (forget_cached_source_info): Not static any more.
1992 (init_source_path): New default source path is "$cdir:$cwd".
1993 (dir_command): Handle variable arguments ($cdir, $cwd).
1994 (source_info): Print "Compilation directory" rather than
1995 "Originally compiled in" to remind people of $cdir.
1996 (openp): If the path contains $cwd, use current directory.
1997 (open_source_file): If compilation directory is known, replace
1998 first $cdir in path with the compilation directory.
1999 (print_source_lines): Even if we can't print the lines, set the
2000 current symtab and line for future commands like "info source" or
2001 "breakpoint". Also, error message now contains the file name,
2002 line number, and file access error message.
2003 (_initialize_source): Fix help text to describe changes.
2004 * main.c (cd_command): Forget cached source info when we chdir.
2005 * utils.c (strstr): Add simple implementation.

2010 Byte-swap COFF symbol tables if necessary when reading them in.
2011 Use complain() to replace error message in one spot. Needs
2012 corresponding change in bfd/coff-code.h to make some symbol
2013 swapping routines non-static.
2015 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2017 Merge changes from Eirik Fuller, for UTek.

2025 declarations of errno.
2027 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2029 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2030 <rpc/rpc.h> and <rpc/types.h>.
2032 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2034 * i960-tdep.c (examine_prologue): Add new argument limit,
2035 which stops the scan at the end of the prologue, or at the PC.
2036 This fixes a problem where it walks down into the code for the
2037 user's statements if that code looks like function prologues.
2038 Mark Fox and I have been bouncing this code back and forth, making
2039 small changes to it. Callers changed to match.
2041 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2043 Cleanup for gdb-3.94 release final:
2045 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2046 the .c files from vx-share and nindy-share, from the various
2047 macros, since they are not found via ALLDEPFILES.
2048 (SFILES): Add tm-i960.h.
2049 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2050 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2052 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2053 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

2057 * am29k-tdep.c: Add contribution line.
2058 (examine_prologue): Cache information about function prologues in
2059 the misc-function-vector to avoid lots of references over the
2060 serial line while examining instructions.
2062 * core.c (core_close): New function made from cleanup_core.
2064 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2065 remote-vx.c, remote.c, target.c, target.h,
2066 Update target_ops vector to add attach, close, and load entries.
2067 Use add_syms_addr_command, not add_file_addr_command, for
2068 add_file. Break out close routine from existing code.
2070 * dbxread.c (really_free_pendings): Don't free pending_blocks;
2071 they are in an obstack.
2072 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
2074 (define_symbol): Add symbol type parameter; change callers;
2075 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
2076 it to influence the symbol class on the i960.
2077 (define_symbol): Swap LOC_CONST's into target byte order.
2079 * exec.c (exec_close): New function.
2080 (exec_file_command): Call it.
2082 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
2083 Fix byte order of frame pointer.
2084 (read_var_value): Result of 0 if var's value can't be found,
2085 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
2086 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
2087 (locate_var_value): Use read_var_value and use its lazy address
2088 as the location of the var's value. Lint.
2090 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
2093 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
2094 obsolete Intel versions in favor of vxgdb versions.
2095 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
2096 code dealing with byte order of values, which Intel did in host byte
2097 order rather than gdb-4's target byte order.
2098 (i960_frame_chain_valid): Move to nindy-tdep.c.
2099 (examine_prologue, skip_prologue, frame_find_saved_regs,
2100 frame_args_address, leafproc_return, saved_pc_after_call,
2101 pop_frame): Add vxgdb versions from Mark Fox.
2102 (examine_prologue, frame_struct_result_address): Add code
2103 to deal with the saved value of G13 (struct return address
2105 (frame_args_address): Modify Mark's version to prefer the
2106 saved value over the current value in the topmost frame.
2107 Cache result in the frame info to avoid performance hair in
2109 (print_fault): Add gdb960 code for printing faults.
2110 (_initialize_i960): Actually call check_host.
2112 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
2113 add stub routines. FIXME, these currently just return zero!
2115 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
2116 (attach_command): Call target_attach, not target_open, now.
2118 * infrun.c (normal_stop): Make global, not static, for vx_attach.
2119 (child_attach): Rename from child_open.
2120 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
2121 don't confuse it with a zero step_resume_break_address.
2123 * inftarg.c (child_detach): Eliminate inferior_pid test.
2124 (child_files_info): Clean up message a bit.
2125 (child_ops): Use child_attach, not child_open, to attach.
2127 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
2128 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
2129 findvar.c to here, since it depends on the contents of the
2130 shadow_contents of breakpoints, but keep if #if 0 since it is
2133 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
2136 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
2137 (ptype_command, display_command): Eliminate have_inferior_p and
2138 have_core_file_p in favor of target_has_stack or
2139 target_has_execution.
2140 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
2141 code for actually finding the values of arguments, though we still
2142 keep track of the maximum stack offset for use in printing unnamed
2143 arguments. Handle missing FRAME_ARGS_ADDRESS.
2145 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
2146 (struct nindy_regs): Define registers passed to/from nindy.
2147 (nindy_fetch_registers, nindy_store-registers): Translate between
2148 nindy and GDB formats for the registers.
2149 (dcache_init): Statically allocate the cache, since it was being
2150 allocated by a malloc that was never freed anyway.
2151 (nindy_create_inferior): Error, not core dump, if no exec file.
2152 (nindy_before_main_loop): Use target_load, not target_add_file.
2154 * remote-vx.c (net_load): Specify large timeout for load
2155 requests. Allow user to break out with INTERRUPT.
2156 (net_break): Remove useless code, clean up. Change callers.
2157 (parse-args, skip_white_space, find_white_space): Clean up arg
2158 parsing to cope with quoted strings.
2159 (net_wait, net_quit): Never call error, just return status.
2160 (vx_read_register, vx_write_register): Cleanup status checking.
2161 #ifdef the code based on which CPU we are using (960 or 68k),
2162 FIXME, this should be completely general but it isn't yet.
2163 (vx_xfer_memory, vx_resume): Cleanup status checking.
2164 (vx_run_files_info): Improve message.
2165 (vx_load_command): Renamed from vx_add_file_command. Allow load
2167 (net_ptrace): Remove unused routine.
2168 (vx_wait): Adopt code from vxgdb960 to cope with broken
2169 connections to target machine and prompt to disconnect. Remove
2170 debug printouts. Map some EVENT_'s to SIGnals.
2171 (add_symbol_stub, vx_open): Print names of object files we found,
2172 and "ok" if we read their symbols OK. Clarify output in general.
2173 (vx_attach, vx_detach, vx_kill): Add these commands.
2174 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
2175 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
2176 "info files" output, and create_inferior, since we already have
2179 * stack.c (frame_info): Replace Frame_unknown with 0.
2180 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
2181 (return_command): Pop until the PC matches as well as the FP,
2182 so it works even if the FP is shared with another function,
2183 as in "frameless" or "leaf" procedures.
2185 * symfile.c (load_command): renamed from add_file_target_command.
2186 (add_syms_addr_command): renamed from add_file_addr_command.
2187 (add_syms_command): Stub to call target_add_syms.
2188 (_initialize_symfile): Change command names and descriptions,
2189 add-file => add-syms, and load from alias to its own command.
2191 * target.c (kill_or_be_killed, maybe_kill_then_attach,
2192 maybe_kill_then_create_inferior): Default for attempts to start
2193 a process, if one is already running, is to ask about killing
2194 it and retry if yes.
2195 (upstack_create_inferior): #if-0 it, strata obsolete it.
2196 (push_target, unpush_target, pop_target): to_close() a target
2197 before unstacking it.
2198 (target_info): Renamed from target_files_info.
2199 (_initialize_targets): Rename "i files" as "i target", accessible
2202 * target.h: Improve comments about the target_ vectored routines.
2204 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
2205 Convert commenting style to standard GNU style.
2206 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
2207 (SKIP_PROLOGUE): No longer a no-op.
2208 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
2209 (*_REGNUM): Sort register numbers.
2210 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
2211 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
2212 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
2213 are now 10 byte extendeds, not 8 byte doubles.
2214 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
2215 for nindy versus vxworks targets. FIXME, this should possibly go
2216 in the target vector.
2217 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
2218 frame_saved_regs and arg pointer with each frame.
2219 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
2220 (FRAME_ARGS_ADDRESS): Use cached result.
2221 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
2222 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
2223 (PRINT_RAMDON_SIGNAL): Call print_fault.
2224 (POP_FRAME): Now works.
2226 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
2227 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
2228 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
2229 (ADDITIONAL_OPTION_HANDLER): use target_load, not
2232 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
2233 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
2235 * valarith.c (value_subscripted_rvalue): Avoid handling
2236 floats and doubles specially; it gave alignment errors. Lint.
2238 * valops.c (value_of_variable, value_of_this): Error if unknown
2241 * valprint.c (print_floating): Bcopy rather than pointer-deref,
2242 to avoid alignment problems.
2243 (value_print): Handle unknown value address.
2244 (cplus_val_print): Two args are ignored; remove them. Change caller.
2245 (val_print): Use unpack_long rather than pointer-deref.
2248 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
2249 to avoid alignment problems.
2250 (value_being_returned): Error if return value unknown.
2251 (set_return_value): Add bogosity warning, FIXME. *
2253 * TODO: A woman's work is never done.
2255 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
2256 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
2257 Add ieee-float.o to OBS.
2258 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
2259 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
2260 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
2262 Changes to generalize the VxWorks RPC protocol slightly, to handle
2263 i960 as well as 68000.
2265 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
2266 * vx-share/reg.h: Produce i960 regs #ifdef I80960
2267 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
2268 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
2269 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
2270 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
2271 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
2272 so they will move in target byte order rather than network
2273 byte order (happens to be the same).
2275 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2277 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
2279 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2282 Add contribution lines to various files, showing where they
2285 * breakpoint.c (break_insn, check_break_insn_size,
2286 read_memory_nobpt): Remove to mem-break.c.
2288 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
2291 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
2292 entry has bad register number. This change is not
2293 tested in this release, FIXME.
2295 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
2298 * value.h: Force value's contents field to be aligned to hold
2299 at least a double or a long long (if supported). This avoids
2300 doing bcopy's in and out of the contents field.
2302 (step_1): Avoid coredump under obscure circumstances when we
2305 * symtab.h (misc_info): Add field to misc function vector for
2306 any kind of cached information the target code desires. AMD
2307 29000 uses this to avoid repeating examine_function_prologue's.
2309 * coffread.c: Lint. Remove static symfile, read_section_header.
2310 core.c (have_core_file_p): Lint: remove.
2311 expprint.c (print_subexp): Lint.
2312 infptrace.c, valops.c, valprint.c: lint.
2314 Roll in changes from vxgdb-5.0.1:
2316 * symtab.h: Comment byte order of each address class. Add
2317 LOC_LOCAL_ARG for frame-relative args (960).
2318 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
2319 symtab.c, symmisc.c: ditto.
2321 * infrun.c (init_wait_for_inferior): Clear stop_signal.
2323 * remote.c (remote_resume): Error if resume with a signal.
2325 * symfile.c (prim_record_misc_function): Clear misc_info.
2326 (fill_in_vptr_fieldno): Check stub type of arg.
2328 * valops.c (value_cast): Avoid looking up names of types whose
2329 name we don't know, to prevent coredump. Sun CC produces typedef
2330 rtx and the name of *rtx is zero...
2332 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2334 Roll in changes from final AMD 29000 port (Tiemann).
2336 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
2337 for ../include/a.out.encap.h. This might not work now that BFD
2338 is separately compiled. Instead, BFD support for encap will have
2339 to translate machine type 29k into the right COFF_MAGIC.
2341 * infcmd.c: Remove references to inferior_pid that aren't used
2342 in actual ptrace calls; use target_has_execution, etc.
2343 (have_inferior_p): Remove function.
2344 (program_info): Print target info rather than "process number";
2345 avoid gratuitous messages unless from_tty.
2346 (run_stack_dummy, finish_command): Set proceed_to_finish.
2347 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
2348 main.c: Lint. Lose have_inferior_p().
2349 inferior.h (have_inferior_p): Remove, lint.
2350 (proceed_to_finish): Add flag to ask that all regs be saved
2351 by normal_stop, for the few commands that need it, speeding up
2352 serial I/O. Add comments to stop_registers.
2354 * remote-eb.c: Remove newline from breakpoint message we grep
2355 for. Never time out when running the user program.
2359 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2361 Roll in changes from vxgdb-5.0.1:
2363 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
2364 symbol in its raw form, we are processing an unlinked ".o" file.
2365 See if the target environment has assigned it an address, using
2366 target_lookup_symbol (VxWorks does), and enter it into the symtab
2369 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
2370 68k versions for a simpler version that assumes zero FP at bottom.
2371 Fixes bug of truncated stack reports.
2373 * target.h (target_lookup_symbol): Define this routine's args
2374 and result, finally.
2376 * target.c (nosymbol): Default routine for target_lookup_symbol.
2377 (target_default): Default lookup_symbol and call_function too.
2378 (files_info): Only print has_all_memory warning if a non-dummy
2381 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
2382 vx_convert_from_virtual): If target does not have floating point,
2383 zero register "values", and avoid doing cross-net conversions.
2384 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
2385 (vx_open): Rearrange code that attaches to target and reads
2386 symbols for all loaded modules, to work if some of the modules
2387 are not accessible. Add symbol_stub() and add_symbol_stub()
2388 as callbacks from catch_errors(). Allow connect attempt to be
2389 interrupted painlessly with ^C (FIXME, there are still some bugs
2390 if the interrupt happens during symbol reading.). Print
2391 final message with puts_filtered, since symbol messages are
2396 * main.c (catch_errors): Only print errstring if non-null.
2397 (command_loop): Avoid an ioctl per command to test ISATTY.
2399 * remote-vx.c (net_load): make static; avoid sophomoric msg.
2400 (vx_xfer_memory): Return correct result!
2401 (vx_files_info): Indicate whether target has float or not.
2402 (vx_lookup_symbol): Complain, not error, if target gone.
2403 (vx_open): Print "Connected" msg before disabling immediate-quit.
2404 [FIXME: lookup_symbol and vx_open changes need testing.]
2406 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
2407 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
2408 contributor lines and update copyrights to 1991.
2410 Changes from an attempted H-PUX host port:
2412 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
2413 defines PT_ATTACH and PT_DETACH but not PT_KILL.
2414 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
2415 * remote-vx.c: include <sys/time.h> for HPUX.
2416 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
2417 "core_file_command" routine to BFD regime. May not work yet.
2419 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
2421 * xgdb.c: Replace X10 version with some VJ version.
2422 (FIXME: Its copyright assignment is not on record.)
2423 * xgdb.c: Update include files to X11R4 (Xaw crud).
2424 (xgdb_display_source, create_text_widget): fix call to
2425 get_filename_and_charpos. Rewack source window stuff for X11R4
2426 (gleaned from include files, and "nm's" of binary libraries, since
2427 I had no doc available).
2428 (append_selection, append_selection_word): Disable with FIXME
2429 since R4 changed interface here.
2430 (create_buttons): Add back the old set of buttons.
2431 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
2433 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
2434 Roll VERSION to 3.94 (not yet final though).
2436 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2438 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
2439 obstack_int_grow, obstack_int_grow_fast): Eliminate
2440 cast on left of assignment, which gives MIPS cc fits and is
2443 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
2444 F_ALIAS. Use printf, not fprintf, when not passing a file
2446 (compare_opcodes): Check that identical instructions have
2447 identical opcodes, complain otherwise.
2449 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
2450 was reported by Roland McGrath.
2451 (unimp): Only match if exactly zero instruction. (Roland)
2452 (branches and traps): Generate all variations of these
2453 instructions with macros, based on a single call that defines
2454 each condition name and its binary representation.
2455 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
2457 * valprint.c (val_print_fields): Take, and use, format parameter.
2458 This means that "p/x struct" again prints the elements in the
2459 desired format. Changed callers.
2461 * stack.c (frame_info): Use filtered output, and indicate wrap
2462 points. Remove kludgy formatting designed to avoid line wrap.
2464 * utils.c (wrap_here): If the line is already full (because
2465 we had printed a long indent or long wrapped string), do an
2466 immediate newline-and-indent.
2468 * m68k-pinsn.c (print_insn_arg): Bugfix from
2469 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
2470 instruction is incorrectly disassembled as bkpt #8.
2472 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
2473 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
2474 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
2475 and then will dump core (sometimes). I traced it back to an
2476 uninitialized symfile_name in psymtab_to_symtab.
2477 (const_vol_complaint): Add quotes to message.
2478 (define_symbol): Only believe line number if gcc_compiled.
2479 Avoid allocating symbol if we will not return it.
2481 Add target strata support so that newly established targets go
2482 into their right place in the target stack (e.g. a new exec file
2483 doesn't wipe out the ability to access the running process).
2485 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2486 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2487 and initialize it properly in all the targets.
2489 * target.h: Document strata. Change return type of push_target.
2491 * target.c (nomemory): new function for dummy memory access.
2492 (tcomplain): Rename complain, now also used in symfile.c.
2493 (push_target): Push targets within strata. New return value shows
2494 whether new target is on top of stack or not. Always keep dummy
2496 (target_files_info): Ignore dummy target.
2498 * core.c (core_open): Warn user, and skip accessing file, if the
2499 core target is not the topmost target in the stack.
2500 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2503 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2504 target_ops, it doesn't belong there since we have no regs there.
2505 Change name of target from machine => memory to clarify.
2507 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2509 * Freeze version 3.93 for release.
2511 * Makefile.dist: Handle vx-share and nindy-share subdirs
2512 properly when building gdb.tar.Z.
2514 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2515 printed in various places, so I could change just one copy.
2517 * dbxread.c, coffread.c: Change references to bfd->iostream
2518 to cast to FILE *, now that BFD avoids needing types defined
2519 in other header files.
2521 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2523 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2524 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2525 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2526 (actually gcc -Wall).
2528 * dbxread.c: Remove first_global_sym, last_global_sym, since
2529 they are never referenced.
2531 * defs.h (baud_rate): Declare.
2532 main.c: Define it, and add the -b option to set it.
2534 * gdb-int.texinfo: Add text on how to define a new host or target
2535 architecture, prompted by Per Bothner's questions about MIPS
2538 * gdb.texinfo: Document "complaints". Change doc of -q since
2539 gdb no longer prints the copyright and blurb if you specify a file
2540 name to be debugged (just like Emacs). Add doc for Nindy-specific
2541 command line flags for specifying target serial port and such.
2542 Update copyright to 1991.
2544 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2545 has taken over for us the job of ripping up executable files. The
2546 crud caused Per Bothner's port to not compile.
2548 * infrun.c (normal_stop): Avoid printing "Program exited
2549 normally" if we are in batch mode. This allows a GDB which
2550 executes a program on a target system, to behave like a Unix
2551 command (input from stdin, output to stdout, no extraneous
2554 * main.c (main): Allow additional machine-dependent command line
2555 options to be specified with the ADDITIONAL_OPTIONS,
2556 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2557 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2558 processing to occur just before the main loop with
2559 BEFORE_MAIN_LOOP_HOOK.
2560 (main): If a "core file" argument is specified, and it is not a
2561 core file, try it as a process ID to attach.
2562 (symbol_completion_function): Attempt to cope with
2563 "show screen-" TAB, not very successfully. This needs more work,
2565 (batch_file): New function, returns whether we are reading
2566 commands from an interactive tty on stdin, or from somewhere else.
2567 Called by normal_stop since it doesn't get from_tty passed down
2568 to it like many commands do.
2570 * remote-nindy.c: Handle command line options for nindy
2572 (nindy_before_main_loop): Prompt user for tty name if they
2573 don't specify it before getting to the interactive command loop.
2575 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2576 and -r command line options. Also add hook before main loop
2577 to make it easy to specify a tty.
2579 * TODO: More things to do, one done.
2581 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2583 * dbxread.c: Make complaint() calls pass pointer, not struct.
2584 Add complaints about badly formatted C++ type information
2585 (const/volatile indicator, and parse errors resulting in
2586 error_type). Fix C++ virtual member fn comment.
2587 (read_struct_type): Avoid bumping pointer if we got a parse
2588 error; this prevents our walking beyond the end of a string.
2589 Terminate loop on null char as well as semicolon.
2590 (process_one_symbol): Fix the LBRAC fix so that it uses the
2591 last previous SLINE, FUN, or SO record's PC address. C++ debug
2592 symbols did not have SLINE records in a useful order compared
2593 to the LBRAC records.
2594 (define_symbol): Handle "catch" records.
2596 * symtab.c (check_stub_type): Added new complain
2597 `stub_noname_complain' and added a consistency check to
2598 keep the debugger from crashing when finishing from an
2599 exception frame. A real fix will be needed later.
2601 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2603 * infcmd.c (attach_command): Make global.
2605 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2606 but make them easy to comment out. Perhaps later they should
2607 be enabled by what CPU you configure for? FIXME.
2608 (VERSION): Roll to 3.93.
2609 (pinsn.o): Remove rule for obsolete file.
2610 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2612 Run down a problem that manifested by printing the wrong function
2613 name in stack traces of read_ofile_symtab. Turned out that the
2614 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2615 the LBRAC symbol with an address in the *data* segment, which
2616 blew our binary search through the blocks.
2618 * dbxread.c: Use the complain() facility consistently to bitch
2619 about problems in the symbol file we are reading.
2620 (finish_block): Add code to check the nesting of the blocks;
2621 complain and Procrust them to fit if wrong.
2622 (make_blockvector): Check the order of the blocks, complain
2623 [but don't cope] if wrong.
2624 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2625 symbols to be sure their PC value is greater than the last SLINE
2626 (line number) symbol we've seen, complaining and adopting the
2627 SLINE PC value if wrong.
2629 * symfile.h (struct complaint, complaint_root, complain,
2630 clear_complaints): Add.
2631 * symfile.c (complain, complaint_root, clear_complaints): Add
2632 facility to deal with non-fatal complaints and to regularize their
2634 (symbol_file_add): Clear complaint counters to allow new complaints.
2635 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2637 * dbxread.c (dbx_symfile_read): Remember the address and size
2638 of the string table for the main symbol file, so we won't read it
2640 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2641 to avoid reading the string table yet again. Lint.
2642 (throughout): Improve filtered output, including word wrap.
2643 (read_range_type): Improve Bothner's fix to handle other types too.
2645 * utils.c: Improve line wrap implementation. Handle unlimited
2646 width by making chars_per_line unsigned.
2647 (puts_filtered): New, easy, function.
2649 * defs.h (puts_filtered): add.
2651 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2652 call the identical sort_symtab_syms() in symfile.c instead.
2654 * expread.y: Suggest the `file' command rather than `symbol-file'.
2656 * command.h (enum var_types): Add zinteger for seroable
2658 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2659 nested if's into a switch.
2661 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2662 we did not stop because of a breakpoint (it must have been for
2663 some other reason, like a "stepi"), so don't print anything.
2665 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2666 doesn't include <sys/types.h>, old SunOS's require it for
2669 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2671 A test port of gdb-3.92.6 to the Sony NEWS.
2674 Don't normally link in remote- or vx stuff.
2675 Some of it doesn't compile, and it wastes space for 99% of the users.
2676 Remove reference to no-longer-used HAVE_VPRINTF.
2677 Fixed BFD_DEP typo to BFD_DIR.
2679 Fix cast in arg to bfd_h_getlong.
2680 Make char *prefix be const.
2681 Fix how certain range types are mapped into builtin unsigned int types.
2683 Remove 2 #includes. They cause errors (on Sony, at least),
2684 and aren't needed (they wern't in earlier versions).
2686 print_address_symbolic should never demangle labels
2687 (since it prints *assembler-level* labels).
2689 [This was superseded by the change to printcmd below.]
2692 Add some "volatile" return types to avoid warnings.
2693 If MISSING_VPRINTF add vprintf function and not just macro
2694 (since vprintf is used in printcmd.c).
2696 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2697 (The latter isn't grokked by some PCC-based compilers.)
2699 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2701 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2702 * nindy-share/coffstrip.c
2703 Added some forward declarations (otherwise, gcc complains
2704 about implicit extern redefined as static).
2706 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2708 Changes inspired by Per Bothner:
2709 * printcmd.c (print_address_symbolic): Take additional parameter
2710 specifying whether to demangle.
2711 (print_address): Pass in asm_demangle to control demangling.
2712 (print_address_demangle): New fn, takes explicit arg to control
2714 * utils.c: Add new vars demangle and asm_demangle, and let them
2716 (fputs_demangled): If !demangle, just print the argument.
2717 (fprint_symbol): If !demangle, just print raw symbol.
2718 * valprint.c (val_print): Call print_address_demangle rather than
2719 print_address, to cause demangling to depend on the global
2720 rather than assembler-level demangling setting.
2721 * WHATS.NEW, gdb.texinfo: Document.
2723 * main.c (show_command): Show all settings if no arg.
2724 (initialize_main): Make "info set" the same as naked "show".
2725 * command.c (cmd_show_list): Handle prefix commands in the
2726 list, and print the name of the setting as well as its English
2727 description and value.
2729 Allow gdb functions to specify where a line should wrap if it
2730 exceeds the size of a terminal line. Use it to make the output
2732 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2733 of the right size when screen width changes.
2734 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2735 (wrap_here): New fn, indicates a point in the output where we
2736 should wrap the line rather than just letting it overflow at a
2738 (fputs_filtered): Implement wrapping.
2739 (n_spaces): New fn, returns a pointer to N spaces.
2740 (print_spaces_filtered): Use n_spaces.
2741 * defs.h (n_spaces): Declare.
2742 * stack.c (print_frame_info): Wrap with 4-space indent after
2743 fn name and before filename and line number.
2744 * printcmd.c (print_frame_args): Wrap with 4-space indent
2745 before each argument name is printed.
2746 * valprint.c (value_print): Wrap with no indentation before
2748 (val_print_fields): Wrap with indentation relative to nesting
2749 level before each field name.
2750 (val_print): Wrap with nesting indentation before array elements.
2751 * command.c (do_setshow_command): Avoid extra newlines,
2752 wrap with 4-space indent around values printed, end with period.
2753 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2755 * breakpoint.c (breakpoint_1): Implement addressprint for
2756 "info breakpoints" display. Change file name and line number
2757 format to " at file:nnn" rather than " (file line nnn)".
2758 * gdb.texinfo: Document.
2761 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2763 Frozen for gdb-3.92.6 release.
2765 README, WHATS.NEW: Update for 3.92.6 release.
2767 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2768 coffread.o from configs since it is now built by default.
2769 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2770 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2771 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2772 from configs since it is now built by default.
2774 Makefile.dist: Update for release 3.92.6. Handle files that
2775 have been moved to ../include, ../getopt, or ../bfd. Add
2776 saber.suppress and tests directory. Add config.status to
2777 the release (it will say "none").
2779 coredep.c: Minor formatting fixes.
2781 These changes were made in early December but only checked in now:
2782 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2783 nindy-share/nindy.c: lint
2784 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2785 register values coming back from the target; we store values
2786 in target byte order everywhere.
2788 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2790 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2792 * valprint.c (cplus_val_print, val_print_fields): New functions,
2793 which print C++ objects. They conspire to avoid printing a
2794 virtual base class more than once, following all the twists and
2795 turns of C++ virtual base rules.
2796 (val_print): Call the above rather than do it by hand.
2798 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2799 symbol file, not for added files like shared libs. This really
2800 needs to be generalized to a timestamp per file.
2802 * core.c (cleanup_core): Avoid coredump if no core file.
2804 * config.gdb: Accept -host or -target in place of +host or
2807 * coffread.c (find_linenos): Avoid desupported BFD interface
2808 to line numbers. We still read them manually rather than using
2809 BFD's "generic" features.
2811 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2813 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2815 * Makefile.dist: Eliminate use of $< in explicit targets.
2817 * readline/Makefile: Use $< rather than $*.c, which does not
2818 include the VPATH in GNU Make.
2820 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2821 copies of tconfig/i960, added for global configuration
2822 compatability. All i960 versions can read both coff and b.out.
2824 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2825 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2828 * TODO: Think of more things to do.
2830 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2832 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2833 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2834 64-bit float conversion.
2836 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2837 equivalent to sun?os4 so global config works.
2839 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2841 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2843 * main.c: Only declare linesize once; declare pagesize not at
2844 all, since it is never used.
2845 (main): Clear newly allocated line before it is used.
2847 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2849 Further stabilization for the Intel 960.
2851 * Makefile.dist: Parameterize the location of the "include"
2852 and "bfd" directories, as well as "getopt". Add symfile.c.
2853 Link in both dbxread and coffread. Fix up "make depend" to
2854 rewack the locations of include, bfd, and getopt in its output.
2856 * README: Document moving include files, improve some of
2859 * coffread.c: Move common code out to symfile.c. Change
2860 symbol_file_command style interface to use new *_symfile_init
2861 and *_symfile_read interface under BFD. Use BFD internal
2862 info to locate line table, symbols, etc.
2864 * core.c (core_fetch_registers): Rename to get_core_registers
2865 to avoid confusion with fetch_core_registers.
2866 (register_addr): Move to coredep.c, which is already machine
2867 dependent. This leaves core.c pretty clean of dependencies.
2869 * coredep.c (register_addr): Accept this routine from core.c.
2871 * dbxread.c: Move common code (with coffread.c, etc) into new
2872 symfile.c. Each psymtab now contains a pointer to the
2873 format-dependent function that knows how to read it in. Make
2875 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2876 (process_one_symbol): Add code to complain about a "compiler bug
2877 we muzzle here", if we actually see it.
2879 * eval.c (evaluate_subexp): Insert missing "break" statements
2880 in code that determines whether a variable is an lvalue in
2881 memory, register, or whatever. I detected this via a compiler
2882 bug in which it *almost* mashed out the whole switch statement.
2884 * gdb-int.texinfo: Add minor sections on configuring gdb for
2885 release, and about the README file.
2887 * infcmd.c (registers_info): Fix formatting somewhat. Still
2888 not as pretty as before, but it handles byte swapping.
2890 * remote-nindy.c: If data cache routines are interrupted while
2891 waiting for the remote end, be sure that any uninitialized cache
2892 blocks are on the free list, not on the valid list!
2894 * symfile.h: Flesh out this header file with all the various
2895 routines and variables that have been merged in from dbxread.c
2896 coffread.c, and symtab.c to symfile.c.
2898 * symfile.c: New file, containing code common to dbxread.c,
2899 coffread.c, and some code from symtab.c. All generic code for
2900 reading symbol files should be in here now.
2901 (unrecord_misc_function): Remove unused function.
2903 * symtab.h: Remove file-reading things to symfile.h.
2905 * symtab.c: Remove file-reading things to symfile.c.
2907 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2908 to decode i960 fault types.
2910 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2911 target.c: Change type of the "resume" function from int to void,
2912 since its result was never used.
2914 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2916 * main.c: Replace "stupid" with "caution"; you now "set caution
2919 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2921 * infcmd.c (do_registers_info): Call val_print to deal with the
2922 byte order of the registers being printed. FIXME, this makes
2923 the formatting of the output uglier.
2925 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2926 defined, call it for signals the debugger doesn't itself use.
2927 The i960 uses this for more detailed fault information.
2929 * remote.c (remote_open): If arg is null, print help rather than
2932 * sparc-xdep.c (register_valid): Avoid declaring size, since
2933 various modules will think of various sizes depending on the
2934 architecture of their tm-file. FIXME, we need protection against
2935 actually entering one of those modules, which would clobber
2936 storage if not for the target architecture compiled into gdb.
2938 * stack.c (up_command, down_command): Always print the frame
2940 (up_silently_command, down_silently_command): New commands
2943 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2945 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2946 more parameters than it used to.
2948 * findvar.c (registers): Increase slop to 256 bytes, which should
2949 protect us against even most RISC machines with large register
2951 (locate_var_value): Move declaration inside related ifdef.
2953 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2954 throughout, to avoid throwing away buffered input from the board.
2955 (nindy_wait): Supply_register takes addr_of_value, not value.
2956 (i960_print_fault): Renamed from i80960_fault.
2957 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2958 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2960 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2961 we can set the PC in the call to proceed(). Unpush nindy_ops
2962 before pushing it on top, to avoid message to user. Eliminate
2963 commentary from Unix machines that just misleads here.
2964 (reset_command): Fix error message to suggest target command.
2966 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2968 Release 3.92.5 as frozen.
2970 Stabilize the merged release...with help from lint, Saber C,
2973 Everywhere: Add include files needed to declare return types
2974 of functions called.
2976 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2978 * breakpoint.h: Add undeclared breakpoint functions, and some
2979 functions for display handling since I couldn't think of a better
2982 * breakpoint.c (insert_breakpoints): Make code for disabling
2983 shared library bkpts more likely to work. It's used when we
2984 rerun a program and stop before the shared library has been
2986 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2987 cast from pointer, so it squeezes through catch_errors.
2988 (bpstat_stop_status): Fix logic broken some time ago. We now
2989 always create a bpstat if the stop address matches a breakpoint,
2990 even if we don't stop there -- just like the old code used to do
2991 before I got my fingers into it (sigh).
2992 (breakpoint_1): Print "ignore count" after "stop only if"
2993 condition, since that's how it actually works.
2994 (mention): Handle watchpoints as well as breakpoints.
2995 (watch_command): use set_raw_breakpoint and mention to do most
2996 of the work (and initialize all the fields!). Only pass one
2997 arg to parse_c_expression, since that's all it takes.
2999 * command.c (not_just_help_class_command): Rename arg to args
3000 since we ignore "unused argument" warnings on vars named "args".
3001 inflow.c (child_terminal_info): ditto.
3002 infptrace.c (kill_inferior): ditto
3003 main.c (catch_errors, version_info, quit_command, pwd_command,
3004 source_command, dump_me_command, editing_info,
3005 set_history_size_command, set_history, show_history,
3007 stack.c (locals_info): ditto
3008 target.c (target_files_info): ditto
3009 valprint.c (set_input_radix, set_output_radix): ditto
3011 * core.c: Remove old variables for handling core and exec file
3012 sections (data_start, data_end, stack_start, stack_end,
3013 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3014 text_end, exec_data_start, exec_data_end, text_offset,
3015 exec_data_offset, data_offset, stack_offset). They're
3016 superseded the more general build_section_table and
3018 (get_exec_file): Mention the `file' command.
3019 (read_memory_check): Rename to memory_error, and only call it
3020 in the case of an actual error.
3021 (read_memory, write_memory): call memory_error.
3022 (core_fetch_registers): Register section name is ".reg".
3024 coredep.c: Remove a bunch of crud now that all this file does
3025 is pull the registers out of a core file.
3026 (fetch_core_registers): Rewrite to actually work, I hope.
3028 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3029 Replace index() with strchr(). Remove all the pre-BFD macro
3030 definitions for accessing the symbol file.
3031 (struct dbx_symfile_info): Encapsulate the information that
3032 dbx_symfile_init needs to pass to dbx_symfile_read in this
3035 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3036 dbx_symfile_discard): Rearrange symbol file reading to divide
3037 the format-specific part from the format-independent part,
3038 leaving the format-independent part such as file name expansion
3039 and opening in symtab.c. This replaces
3040 partial_symbol_file_open and partial_symbol_file_read.
3041 Symbol_file_read, add_file, add_file_target_command,
3042 add_file_addr_command move to symtab.c. Pass an explicit
3043 "mainline" flag for when reading the main symbol table, rather
3044 than relying on the offset address to be zero or nonzero.
3046 (dbx_symfile_read): Don't allow void *'s to be printed as
3048 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3049 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3050 macro" debug version really work.
3051 (read_dbx_symtab): Remove unref'd parameter inclink.
3052 Avoid swapping N_SLINE symbols, for speed.
3053 Merge N_TEXT!N_EXT case with the other external symbol
3054 definitions' case. Add comments.
3055 (start_psymtab): Allocate the symfile name in the psymtab on
3056 the psymbol_obstack, rather than using the caller's storage.
3057 (end_psymtab): Only allocate a dependencies list if there are
3059 (psymtab_to_symtab_2): Use BFD when reopening file to read
3060 its symbols for real.
3061 (read_struct_type): Add FIXME comments where it needs work
3063 (read_huge_number): Add FIXME about overflows.
3064 (read_range_type): Add FIXME about comparing a long to 1<<32.
3066 * coffread.c: Minor changes to move things closer to the new
3067 regime with symtab.c and dbxread.c Major work is still needed
3070 * exec.c (exec_file_command): Remove old variables (see core.c
3072 (xfer_memory): If memory transfer is right at the end of a
3073 section, don't lose.
3075 * findvar.c (get_saved_register): If value is in a real
3076 register, LVAL is lval_register, not lval_memory.
3078 frame.h: Declare print_sel_frame and record_selected_frame.
3080 gdb-int.texinfo: New file, for GDB internals documentation.
3081 Very simple, unformatted doc of cleanups is there for now.
3083 gdbcore.h: Remove obsolete variables that described a.out
3084 section addresses and offsets. (See core.c above.)
3085 Declare fetch_core_registers and registers_fetched.
3087 getopt.c: Declare char *alloca(); even on SPARC.
3089 infcmd.c (run_command): Call target_kill rather than
3091 (step_command, next_command, stepi_command, nexti_command):
3092 Declare from_tty parameter even though we don't use it.
3093 (run_stack_dummy): argument BUFFER is a char array, not
3094 a pointer to REGISTER_TYPE.
3095 (finish_command): using_struct_return needed a value *,
3096 not a struct symbol *.
3098 * infptrace.c (child_xfer_memory): To avoid dependency on
3099 where sections are in memory, try PT_WRITE_D and if that fails,
3100 try PT_WRITE_I. Most Unixes don't care which you use.
3102 * infrun.c (step_resume_break_shadow): Change to array to
3103 match other breakpoint shadow storage.
3104 (clear_proceed_status): Pass address of bpstat to
3105 bpstat_clear, not the bpstat itself.
3106 (child_create_inferior): FIXME comment about if the child
3108 (start_inferior): Remove old function.
3109 (child_open): Use target_kill rather than kill_inferior.
3110 (wait_for_inferior): Ditto.
3111 (insert_step_breakpoint, remote_step_breakpoint): Use
3112 new step_resume_break_shadow.
3114 * inftarg.c (child_wait): If all child processes die,
3115 pretend that the one being waited for exited with signal 42.
3117 * main.c (command_line_input): When scanning for comments,
3118 don't coredump on unclosed quotes.
3119 (quit_command): Use target_kill rther than kill_inferior.
3120 (_initialize_main): Rename class_user from "user" to
3123 * printcmd.c (print_command_1): Initialize "fmt" if no format
3124 is specified by the user.
3125 (print_frame_args): Only add to args_printed if we are
3126 actually fetching args from the stack (avoiding undefined
3128 (_initialize_printcmd): Remove bogus \{ from string.
3130 * remote-eb.c (eb_open): Avoid coredump on no argument.
3132 * remote-nindy.c: Bring out of Intel environment into new
3133 target environment. Remove all conditional compilation on
3134 I80960. Massive hacking throughout.
3135 (nindy_xfer_inferior_memory): New routine stolen from
3137 (nindy_create_inferior): New routine pieced together, probably
3138 not quite working yet.
3139 (nindy_ops): New target_ops struct for nindy.
3141 * remote-vx.c: Use write_memory rather than target_write_memory
3142 to get error checking.
3143 (vx_add_file_command, vx_open): Use symbol_file_add rather than
3145 (vx_create_inferior): Use target_terminal_ours...
3147 * signame.c (_initialize_signame): Always initialize, since
3148 we need the table for things other than psignal.
3150 * solib.c (solib_add): Use symbol_file_add, not add_file.
3151 (solib_address): Return boolean result rather than struct
3152 pointer which nobody else knows the type of.
3154 * sparc-tdep.c, valops.c: Use write_memory rather than
3155 target_write_memory, to get error checking.
3157 * stack.c (locals_info, catch_info, args_info,
3158 get_selected_block, frame_command, up_command): Use
3159 target_has_stack, rather than have_inferior_p or
3162 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
3164 * symfile.h: New file, defining the interface between the
3165 generic and object-file-specific symbol reading code.
3167 * symtab.c: Move generic symbol-reading interface to symtab.c,
3168 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
3169 table to map BFD targets to symbol-reading modules in GDB.
3170 Change index to strchr.
3171 (lookup_struct_elt_type): Use error() rather than hand-made
3172 simulations thereof.
3173 (lookup_partial_symbol): Speedup slightly when length == 0.
3174 (symbol_file_add): New function.
3175 (symbol_file_command): Call it.
3176 (symfile_open, symfile_init): New function.
3177 (add_file_target_command, add_file_addr_command): moved from
3180 * target.c (target_command): use target_kill.
3182 * target.h (target_files_info): Don't declare, never called
3185 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
3186 files to determine stack end address.
3188 * valarith.c (value_x_binop, value_x_unop): Change error message
3189 to be more useful. Pass proper argument to value_struct_elt.
3191 * valops.c (value_assign): FIXME comment that long long
3192 bitfields will break here.
3194 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
3195 Update `make saber_gdb' to work better.
3197 * TODO: A woman's work is never done.
3199 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
3200 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
3201 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
3202 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
3203 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
3204 valops.c, valprint.c, exec.c: Lint.
3207 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
3209 Continuing Intel 960 port merge of GDB.
3211 * Makefile.dist: Merge i960 "nindy-share" files. Rename
3212 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
3213 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
3214 Wack over "make depend" so it handles files in subdirectories
3215 vx-share, nindy-share, bfd, and in the current directory.
3217 * blockframe.c (get_prev_frame_info): Remove fatal error
3218 if stack not defined.
3220 * core.c (core_open, core_detach): New functions that handle
3221 the old "core-file" command as "target core" and "detach" instead.
3222 (core_file_command): Call them.
3223 (core_xfer_memory): Use common routine xfer_memory.
3225 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
3226 dbxread now uses bfd for everything but symbol reading itself.
3227 BFD internals are used to drag out the relevant file offsets.
3228 (partial_symbol_file_open): Change args all around for BFD.
3230 * symtab.c: Rename "value" to "val" everywhere, so we can
3232 (symbol_file_command): New command, moved from dbxread.c
3233 and coffread.c. It uses BFD to read the file, then vectors
3234 based on its type, to dbx or coff symbol readers.
3235 * symtab.h: Extern a few vars for symbol_file_command.
3237 * target.h: Breakpoint takes a char * save area, not a char **.
3239 * valprint.c (val_print): When unpacking bitfields, offset
3240 the address in gdb of the value, if it is declared with a shorter
3241 type. Remove the last "runtime kludge test" of host byte order.
3243 * utils.c: Remove old my_bfd_read routine.
3245 * stack.c (frame_info): Use target_has_stack. Print program counter
3246 register's actual name rather than "pc", since it's called the
3247 "ip" (instruction pointer) on the i960 (sigh).
3249 * target.c (target_command): Add command for selecting a target
3250 type and calling its open routine. This is used for initiating
3251 communication with a particular target, in a generic way.
3253 * tm-i960.h: Update for modern gdb. Remove semicolons from
3254 various macros. Handle reading struct return convention, and
3255 error-out attempts to return structs with the "return" command.
3256 Be sure gdb doesn't think we know how to call functions in the
3259 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
3260 to i960_xxx in lower case.
3261 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
3262 not being defined yet.
3264 * remote.c (remote_open): Call start_remote to initialize
3265 wait_for_inferior during open.
3266 (remote_xfer_inferior_memory): Return length written rather
3269 * remote-vx.c (target_command -> vx_open): Use new generic
3271 * remote-eb.c, inftarg.c, exec.c: ditto.
3273 * infrun.c: Fix comments.
3274 (attach_program -> child_open): Use new generic target command.
3275 (wait_for_inferior): Clear saved register values before target_wait,
3276 so target_wait can set some of them if convenient.
3278 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
3279 Return success indicator, not void.
3280 (child_xfer_memory): Avoid fetching initial word if we'll
3281 overwrite it anyway.
3283 * infcmd.c (attach_command): Use new generic target open routine.
3284 (_initialize_infcmd): Update doc on attach and detach commands.
3285 (do_registers_info): Merge in a byte-order problem as a FIXME
3288 * findvar.c (find_saved_register): Avoid problem in current frame.
3289 (read_relative_register): Ditto.
3290 (write_register): Convert byte order on the way out.
3292 * exec.c (file_command): Add.
3293 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
3294 (xfer_memory): Common function between core_xfer_memory and
3296 (exec_xfer_memory): Use it.
3298 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
3300 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
3301 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
3302 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
3304 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
3306 Merge Intel 960 port of gdb, continuing...
3308 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
3309 symbol_file_command): Pass from_tty arg to hush 'em up.
3311 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
3312 Add magic numbers for 960 COFF format.
3314 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
3316 Merge Intel 960 port of gdb, from Intel "1.2" release.
3318 CHANGE_LOG entries from their port, which was based on
3321 Thu Sep 6 11:02:22 PDT 1990
3322 Remove temp file if download is interrupted.
3324 Wed Aug 1 09:08:33 PDT 1990
3325 Now uses binary protocol to talk to NINDY.
3326 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
3327 Times out after 5 seconds when trying to talk to NINDY.
3329 Tue May 29 12:54:49 PDT 1990
3330 Added variable baud rate (-b switch).
3331 Source code reorganization.
3333 Thu Apr 26 11:09:55 PDT 1990
3334 More cleanup of batch mode; specifically, execute "-s", "-e", and
3335 "-se" switches as soon as they are encountered on the invocation line.
3337 Fri Apr 20 13:47:15 PDT 1990
3340 Thu Apr 19 09:54:28 PDT 1990
3341 Add 'reset' command.
3343 Wed Apr 18 09:48:07 PDT 1990
3344 After opening remote tty, wait for 1 second to go by without input
3345 from it before trying to talk to NINDY (fixes problems with the
3346 Heurikon HK80/V960E).
3348 Mon Apr 4 16:33:05 PDT 1990
3349 Some output was not being suppressed in 'batch' mode.
3351 Thu Mar 22 15:31:11 PST 1990
3352 Ask user if old symbol table should be deleted when new file is
3355 Allow user to run a program downloaded before gdb960 was brought up.
3357 Correct "exec-file" help message for i80960 context.
3359 Correct bug in calculating user space address: could occasionally
3360 corrupt user program.
3362 Make sure to zero low-order bits in rip's because of bug in 960CA
3363 A-step part: could cause operation faults when "next"ing across
3366 Correct bug that made it impossible to get source line numbers for
3367 code loaded at addresses higher than 0x7fffffff.
3369 Wed Jan 10 12:43:22 PST 1990
3370 Open remote tty for exclusive use.
3372 Fri Jan 5 12:14:42 PST 1990
3373 Correct disassembly (CA manual was right after all):
3374 opcode for sysctl is 0x659
3376 Mon Oct 23 12:03:04 PDT 1989
3377 Use G960BASE and G960BIN environment variables to find 'sx' utility.
3379 Mon Oct 16 14:15:09 PDT 1989
3380 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
3382 Mon Oct 2 15:56:31 PDT 1989
3384 Added 960CA disassembly support.
3386 To simplify maintenance:
3387 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
3389 - eliminated opcode.h: incorporates tables into i960-pinsn.c
3390 - moved 960-specific routines from i960-pinsn.c to i960-md.c
3391 - made disassembly interface identical to that in gdmp960.
3395 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
3397 * target.h: Allow targets to stack. Add target_has_memory,
3398 _registers, etc. Restructure memory access and "info files"
3399 to walk the target stack.
3400 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
3401 target.c: Change tables to match target.h.
3402 * inflow.c (child_mourn_inferior): pop child_ops.
3403 (generic_mourn_inferior): Use new has_stack flag.
3404 * infptrace.c (child_xfer_memory): New memory regime.
3405 * inftarg.c (child_files_info): New "info files" regime.
3406 * remote-eb.c: New memory regime, new info files.
3407 * remote-vx.c: New memory regime, new info files. Now use
3408 separate targets for VxWorks attachment to machine, and
3409 actually running a process under VxWorks, since one has
3410 stack & execution & regs and the other doesn't.
3411 * remote.c: New memory regime, new info files.
3412 * sparc-xdep.c (fetch_core-registers): New memory regime.
3413 * target.c: New routines and support for stacked targets,
3414 new memory regime, new info files regime.
3417 Generalize section handling for an arbitrary number of sections,
3418 including use of the new BFD (binary file) library.
3419 * gdbcore.h: Add struct section_table.
3420 * exec.c (build_section_table): Iterate all sections and
3421 record what gdb needs to know about them.
3422 (exec_command): Use it.
3423 (exec_xfer_memory): Use the table.
3424 (exec_files_info): Print the table.
3425 * core.c (core_file_command, core_xfer_memory, core_files_info):
3427 * source.c (find_source_lines): Use bfd_get_mtime.
3428 * dbxread.c: Quick changes to make it compile with new BFD.
3429 * utils.c (error): Avoid using bfd_error in generic routines.
3431 * core.c (core_fetch_registers): Get from the ".regs" section of
3433 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
3435 * inferior.h (attach_flag): Export.
3436 * infcmd.c (run_command): use new target_create_inferior.
3437 * infrun.c (child_create_inferior): Don't return result.
3438 * Makefile.dist (VERSION): 3.91.4.
3440 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
3442 * breakpoint.c (bpstat_num): Handle breakpoints which have
3443 since been deleted, such as temporary breakpoints.
3444 infcmd.c (program_info): ditto.
3446 * core.c (core_file_command): Display the frame where the core
3451 * remote-vx.c (target_command): Merge in target command from
3452 targ-vx.c. A few other cleanups.
3454 * TODO, Projects: Lots more stuff to do...
3456 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
3458 Massive changes to wall off the remote-debugging interface
3459 behind a function vector. The port to handle VxWorks targets
3460 is also part of this.
3462 All files: Replace references to renamed functions,
3463 remove references to remote_debugging, remove references to
3464 have_include_file, have_core_file in favor of target_has_stack,
3465 target_has_memory, etc.
3467 * Modularize the breakpoint interface.
3468 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
3469 a breakpoint instruction.
3470 breakpoint.c: struct breakpoint's shadow_contents now sized as
3472 (insert_breakpoints): Vector to target to install breakpoints.
3473 (remove_breakpoints): Vector to target here too.
3474 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
3475 sparc-tdep.c (single_step): Use new breakpoint interface for
3476 the single-step breakpoints.
3477 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
3478 New file, contains routines to insert and remove breakpoints by
3479 reading out the old contents and later replacing them. This is
3480 how ptrace breakpoints work, and many remote systems as well.
3482 * tm-vxworks68.h: New config file, overrides a few things for
3483 Wind River's preferences.
3485 * target.h: New file, for transfer vector used to talk to the
3486 inferior (child, attached, core, exec, remote, etc). All accesses
3487 to the thing being debugged should come through these vectors.
3488 target.c: New file, routines to handle transfer vector.
3489 (various files): Add transfer vectors XXX_ops for the various
3490 targets and pseudo-targets (core files, etc) we support.
3492 * breakpoint.c (bpstat_stop_status): Further explorations of
3493 watchpoints and why things don't work all the time.
3494 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3496 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3497 the local gdbinit if it doesn't already have it.
3499 * core.c (core_ops): add and install.
3500 Allow core debugging without exec file.
3502 * dbxread.c (free_and_init_header_files): Merge two fns.
3503 (end_symtab): Free named symbol table when a new version comes in.
3504 (read_dbx_symtab): Relocate all kinds of symbols with base
3505 address. First step toward handling different text, data, bss
3507 (add_file_addr_command): Renamed add_file_command.
3508 (add_file_command): Vector to remote handler.
3509 Add "load" as an alias for "add-file" command.
3511 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3512 non-returning functions.
3514 * exec.c: Add exec_ops, and push it as a target when an exec
3517 * infcmd.c (run_command): Pass executable file name and arg list
3518 separately when starting an inferior. Permit "run" when no exec
3519 file is specified, for VxWorks.
3520 (detach_command): Move to child_detach in inftarg.c.
3522 * inftarg.c: New file. Unix-child-specific routines, and the
3523 child_ops structure.
3525 * inferior.h (registers): Export "registers" as the way for
3526 target dependent register handlers to find gdb's local copy of
3527 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3528 since it is now used by places that want wait_for_inferior to
3529 handle the grunge but want to see every trap from the inferior.
3531 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3532 Eliminate remote_debugging hooks in terminal handling.
3534 * infrun.c: Replace start_inferior with child_create_inferior.
3535 Move all the hair of Unix shells and ptrace idiosyncracies into
3536 child_create_inferior, so remote handlers don't have to deal.
3537 Remove running_in_shell. Rename stop_after_attach to
3538 stop_soon_quietly, and use it in a few other places where we want
3539 to just call wait_for_inferior and get control back on the first
3540 trap. trap_expected now never takes a value > 1.
3541 (init_wait_for_inferior): Initialize static vars when a new
3544 main.c (gdbinit): Add new hook for .gdbinit file name, let
3545 it be overridden by config files as GDBINIT_FILENAME.
3546 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3547 Both of these are used for VxWorks gdb.
3549 mcheck.c: rename include file "gmalloc.c" to avoid problems
3550 with system include file "malloc.c".
3552 param-no-tm.h: New include file, same as param.h but does not
3553 include the default "tm.h" file. This is used in files where
3554 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3556 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3558 remote-vx.c: New file, VxWorks remote debugging support. Uses
3559 RPC routines that are shared with the target system, in directory
3562 remote.c: Vectorize remote interface.
3564 source.c: Globalize source_path, and make an alias "l" for "list"
3565 since we now have the "load" command.
3567 sparc-xdep.c: Use new param-no-tm.h.
3569 symmisc.c (free_named_symtab): Add new function from Wind River.
3570 However, ifdef it out for now while we think about what it should
3573 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3575 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3576 non-Unix-children handle this with their own code in the target
3579 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3580 source and target lists. Add vx-share to default list of include
3581 directories. Add new files to src and target lists: mem-break,
3582 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3583 ${srcdir} versions of munch and createtags are used.
3585 * valops.c (find_function_addr): Split out of call_function.
3586 (call_function_by_hand): Rename call_function; this function
3587 calls functions in the target by laboriously patching the target
3588 word-by-word with the right stack, args, regs, etc.
3591 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3593 Handle AMD 29000 a bit better.
3595 * remote-eb.c (readchar): Mask received char log to make it readable.
3596 (remote_start): Pass arguments down to executing program.
3597 Make startaddr unsigned.
3598 infrun.c (start_inferior): Accept args, pass them to
3600 infcmd.c (run_command): Pass args down to start_inferior.
3602 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3603 the target object file format.
3604 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3606 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3607 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3609 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3611 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3612 * TODO: We did a few things, we have more to do though.
3614 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3615 * inflow.c (inferior_died): Clear deferred stores.
3617 * Debug problems with dummy frames and calls to the inferior.
3618 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
3619 * sparc-tdep.c (do_restore_insn): Simplify.
3620 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3621 (sparc_push_dummy_frame): Simplify and fix what we push.
3622 (sparc_pop_frame): Slightly more hair here, deciding whether
3623 we are restoring a saved PC or returning to a return address in %i7.
3624 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3626 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3627 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3628 * obstack.h (chunkfun): ditto.
3629 * defs.h (xmalloc, xrealloc): ditto
3631 * utils.c (quit): Grab the terminal from the child if necessary.
3633 * inflow.c (term_status_command): Rename to term_info, change
3636 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3637 (is_delayed_branch): Speed up.
3638 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3639 Still missing some float ops, and needs testing.
3641 * Support for input and output radixes other than base 10
3642 * defs.h (input_radix, output_radix): Declare.
3643 * expread.y (yyparse, parse_number): Handle changes of input
3644 radix, and ambiguous names-or-numbers in radixes >10.
3645 * printcmd.c (print_scalar_formatted): Print formatted hex
3646 numbers in varying column widths.
3647 * valprint.c (val_print): Use output_format to print scalar ints.
3648 (set_input_radix, set_output_radix, set_radix): Create.
3649 (set_output_radix): Set output_format from output_radix.
3650 (_initialize_valprint): add `set radix' but leave the others off.
3652 * main.c (execute_command): Let stupid questions be turned off.
3653 (_initialize_main): Handle "set stupidity", etc.
3655 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3656 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3658 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3660 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3661 bfd stuff is still screwed up, but with some manual work, it
3664 * breakpoint.c (bpstat_do_actions): Start over if a command
3665 proceeds the inferior, since the inferior will have stopped and
3666 will need to have its new stop-actions taken care of.
3668 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3669 compiler fits, simplify it.
3671 * gdb.texinfo (directory command): Doc new dir command.
3672 source.c (directory_command): "dir" now puts things on the front
3673 of the path, moves dups up front, and handles multiple names
3674 on the command line, inserting each one in order. It also
3675 blows away cached line and full_filename info.
3677 * stack.c (backtrace_command): Skip "more stack frames follow"
3680 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3681 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3682 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3683 The only odd one was Gould NP1, which had defined vprintf to
3686 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3687 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3688 variable, inspect_it.
3689 valprint.c (print_string, val_print): Use the global inspect_it
3690 to indicate whether to print in Epoch style or normal style.
3692 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3694 * printcmd.c (call_command): add an alias for the "print" command
3695 which runs expressions and doesn't print the result if void.
3696 (print_command_1): implement it.
3698 * command.c: Remove #if 0'd code. Initialize all the fields
3699 in add_cmd (). Rename do_nothing_command to
3700 not_just_help_class_command, and make it externally visible.
3701 command.h: add user_commands to struct.
3702 * main.c (define_command): Don't overload c->function with a char
3703 string as well as a function pointer.
3705 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3706 calling convention of value_struct_elt () that got dropped in
3709 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3710 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3712 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3714 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3715 until a good time (e.g. when we are about to run the child),
3716 saving ptrace calls.
3717 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3718 * tm-sparc.h: define DO_DEFERRED_STORES.
3720 * sparc-xdep.c (store_inferior_registers): when storing float
3721 registers, don't store stack regs too. When storing the SP,
3722 however, DO store the stack regs too. This fixes a bug in which
3723 the dummy frame is not recognized when a call_function finishes,
3724 because its frame pointer (in the stack regs) was never
3726 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3727 even though we don't know how to read them from an inferior.
3728 valops.c (call_function): Comment about storing SP.
3730 * infrun.c (save_inferior_status): Save away the original bpstat
3731 chain so it can be restored later. Install the copied version for
3732 use by whoever saved the status. It will be blow away by
3733 restore_inferior_status, and the original chain restored. This is
3734 important for people who have pointers into the original.
3736 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3737 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3738 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3741 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3743 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3744 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3745 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3747 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3749 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3750 Store the baseclasses in a type struct starting from array element
3751 0 rather than from the unusual array element 1.
3753 dbxread.c: the above.
3754 (virtual_context): Add
3755 Read new debug information about which virtual function table
3756 a virtual function is from, and store it in fn_field.fcontext.
3758 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3759 TYPE_FN_FIELD_STATIC_P.
3761 symtab.c: the above.
3762 valops.c: the above. Handle pointer casts of object *'s.
3763 (search_struct_method): Add.
3764 (value_struct_elt): First arg is now a pointer to a value, and is
3767 valprint.c: the above.
3768 values.c (value_virtual_fn_field): Add type arg. Handle
3769 offsetting to the proper object when calling virtual fns.
3771 (baseclass_addr): Add valuep arg.
3773 * README: Document the current state of BFD config (missing).
3774 * TODO, ChangeLog, Makefile.dist: Roll version.
3775 * WHATS.NEW: Add summary of changes since 3.5.
3777 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3779 * dbxread.c (read_struct_type): Clear bit vectors whenever
3781 symtab.c (B_CLRALL): define.
3783 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3784 using == rather than =. Huh... This fixes the dreaded problem
3785 wherein builtin_type_int becomes TYPE_CODE_FLT.
3787 * core.c (info_files): Show the inferior pid.
3789 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3790 already knows how to look in the source directory.
3792 * Remove psymtab hair from many places. Remove duplicated code
3793 for searching symbol tables. Hide psymtabs from most places.
3794 Make it fast to get from a psymtab to its symtab.
3796 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3797 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3798 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3799 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3800 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3801 new symtab completely. New psymtabs get symtab pointer
3802 initialized to zero. Remove MI warning printf.
3803 symtab.h: Comments. Add psymtab to symtab pointer.
3804 (PSYMTAB_TO_SYMTAB): New macro.
3805 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3806 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3808 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3810 (print_frame_info): Avoid special-casing symbols that have not yet
3813 * source.c (open_source_file): Quick path if we have already
3814 located the source file by its full name.
3816 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3817 find_pc_psymtab. When a name is found in the misc function
3818 vector, search the symbol table for its mangled name, not the
3819 name that the user typed.
3821 * bfd.h: Fix missing comment terminators, make #endifs match.
3823 * valarith.c (value_less): Handle unsigned int comparisons.
3824 Add FIXME about pointer compares, which assume host and target
3825 pointers are the same.
3827 * command.c (do_nothing_command): lint
3828 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3829 fix comments on debug symbol format for visibility. Actually set
3830 visibility of symbols.
3831 main.c (echo_command): lint; use <readline/history.h>.
3832 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3833 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3834 pointing past end of allocated memory; saber complains.
3835 obstack.h: Declare the external functions that we use.
3836 valarith.h: use <string.h>
3837 solib.c (solib_add): lint.
3839 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3841 * main.c (initialize_main): Default info_verbose to off, now that
3842 symbol reading is fast.
3843 (quit_command): Avoid clobbering exec_bfd while quitting.
3845 * Initial BFD (binary file diddling library) merger:
3846 coffread.c: Change AOUTHDR to struct exe_hdr.
3848 core.c: initialize initialized data at compile time.
3849 (core_file_command): Move from coredep.c, convert to bfd.
3850 (xfer_core_file): Convert to bfd.
3851 exec.c (exec_file_command): use bfd routines.
3853 mips-tdep.c: Remove exec_file_command and friends.
3856 * coredep.c: (fetch_core_registers) Convert core_file_command to
3857 fetch_core_registers.
3858 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3860 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3861 (my_bfd_read): More bogosity, which I don't think we call.
3862 (program_name): Remove this atrocity asap!
3864 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3867 values.c: allocate_repeat_value was not clearing the
3868 optimized_out field.
3869 (value_static_field): minor stylistic fix (wrong macro was used).
3870 valops.c (value_struct_elt_for_address): didn't work for C++
3873 * signame.c (_initialize_signame): Initialize signal names once.
3875 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3876 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3877 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3879 * remote-eb.c: Support user-settable baud rates on the serial port.
3881 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3883 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3885 * tconfig/sun3os4: Remove warning about native assembler,
3886 since it also occurs in the xconfig file.
3888 * findvar.c (registers): Allocate some slop after `registers'
3889 to prevent stray accesses from trashing the next variable.
3891 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3892 on the sun-3, by changing the #ifdef from `sun3' (which is not
3893 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3894 vars, which happened to follow `registers' in the executable.
3896 * readline/history.c (history_search): Heed gcc-2's advice
3897 and parenthesize && inside ||).
3899 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3900 tm-29k.c: Insert FSF copyright headers.
3902 * remote-eb.c: Better comments.
3904 * Makefile.dist: Update to 3.91.6.
3905 * TODO: note PREPARE_TO_STORE problem.
3907 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3909 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3911 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3913 * infrun.c (wait_for_inferior, at end): Don't set up
3914 prev_* if the inferior no longer exists.
3916 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3917 CANNOT_EXECUTE_STACK.
3918 valops.c (call_function): Use it.
3920 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3922 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3923 infrun.c (wait_for_inferior, 2 places): Use it.
3925 * values.c (value_being_returned): Only use
3926 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3928 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3929 right thing for remote-eb.c.
3931 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3932 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3934 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3935 (FRAME_FIND_SAVED_REGS).
3937 * findvar.c ({fetch,store}_registers): Check for
3938 REMOTE_{FETCH_STORE}_REGISTER macro.
3940 * findvar.c (get_saved_register): Add argument lval and
3941 change meaning of argument addr.
3942 findvar.c: Change calls to get_saved_register to reflect
3943 new calling convention.
3944 valops.c (value_assign): Use get_saved_register instead of
3945 find_saved_register.
3947 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3949 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3950 an (uninitialized) pointer to one. Use "&" when passing it
3953 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3955 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3958 * coffread.c (symbol_file_command): Put semicolon after
3960 Put safe_to_init_tdesc_context in #if defined (TDESC).
3961 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3962 coffread.c: #include <sys/stat.h>.
3963 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3964 Add missing ')' in check for "lc%" and friends. Remove
3966 Declare read_one_sym() at top of file.
3967 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3968 MC68WRMAGIC can have the same value without causing a duplicate
3971 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3973 * Allow a Makefile to be built without building the
3974 tm and xm file links that screw up builds in subdirectories.
3975 This is done with `config.gdb none', then you can do things
3976 like `make gdb.tar.Z'.
3977 * tconfig/none: Config file for no target system
3978 * xconfig/none: Config file for no host system
3979 * config.gdb: If no TM or XM files are called out by the
3980 host or target file, don't make links for them.
3982 * cplus-dem.c: Add documentation.
3984 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3985 simple error, so the user's gdb doesn't crash due to some object
3986 file problem (e.g. somebody is rebuilding the file out from under
3989 * printcmd.c (print_address_symbolic): demangle the symbol.
3991 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3992 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3993 (alldeps.mak): sort and uniq all results from this; duplicates
3994 hose gdb.tar.Z link building. Remove RCS files from
3995 tconfig and xconfig. Add config files for sun386. Add
3996 a few odd files to OTHERS and HFILES.
3998 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4000 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4001 Roll version number to 3.91.5. Make lint work in bindir.
4003 * README: Document cross-debugging and new file structure.
4005 * blockframe.c: Lint. Include "value.h" to declare read_register.
4006 (find_pc_partial_function): remove duplicate line.
4008 * command.h: Lint. Declare error_no_arg and dont_repeat.
4010 * tm-news.h: Remove inadvertently duplicated stuff.
4012 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4013 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4015 * config.gdb: Allow `config.gdb host target' form. Clean
4016 up previous change that printed bogus messages when you just said
4019 * core.c: #include "command.h" for lint.
4022 * main.c: Remove some casts of enums. Lint.
4029 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4031 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4032 read it from memory. This will allow us to save ptrace calls
4033 eventually. Changed caller single_step too.
4035 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4036 that we aren't going to use, saving many ptrace calls, especially
4037 when watchpointing or single stepping. Use some #define's for
4039 (store_inferior_registers): Ditto.
4040 (core_file_command): Use some #define's for constants.
4042 * tm-sparc.h: Add #define's for some register numbers, so we
4043 can eliminate the use of random constants in sparc-xdep.c.
4045 * stack.c (frame_command, print_frame_info, up_command,
4046 down_command) Remove frame_changed, since it
4047 causes a bug and doesn't seem to do anything useful. In some
4048 places it was used as a flag, in others as a stack level (?).
4050 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4051 default is to use the portable (vprintf) version rather than the
4053 * xm-news.h (MISSING_VPRINTF): Add.
4055 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
4057 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
4059 * Remove stuff that forces -Bstatic linking of gdb, and warnings
4060 about linking debugged programs -Bstatic in the sun?os4 config
4061 files in tconfig and xconfig subdirectories.
4063 * main.c (main): Remove unreached exit(0) now that we exit
4066 * Create TODO file for online bug list. There are too many
4067 "little" bugs to keep track of on paper.
4069 * Change Projects file to refer to bug-gdb@cygnus.com
4070 rather than kingdon@ai.
4072 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
4074 * Makefile.dist (VERSION): 3.91.4 now.
4076 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
4077 (condense_misc_bunches): Add sanity check that misc_count is
4078 the same as the number of symbols in the bunch.
4080 * coffread.c: rename init_misc_bunches. Pass an argument
4081 to condense_misc_bunches (a zero).
4083 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
4084 every time we are called; don't rely on our caller to do it.
4085 (add_file): Remove call to init_misc_bunches.
4087 * mipsread.c: Only warn, don't error, if unknown symbol types.
4088 This keeps an old gdb from falling on its face if it sees newly
4089 extended symbol info. Rename init_misc_bunches.
4091 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
4093 * Merge in changes from Per Bothner for DECstations and other
4094 MIPS stuff. The rest is Bothner speaking:
4096 The next message is a merger of Alessando Forin's mips port with
4097 mine. I've tried to use my good if biased judgment to get
4098 the best of both. It *does* need testing.
4100 Some of the changes are general, *not* mips-specific.
4103 Didn't believe in little-endian bit order.
4104 There are still inconsistencies about whether flags
4105 like BITS_BIG_ENDIAN are integer (#if ...) or
4106 boolean (#ifdef ...). I tried to paper over them.
4108 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
4109 Moved some misc_function code that was common to
4110 {dbx,coff,mips}read.c to symtab.c.
4111 In the process, I think I cleaned things up a bit.
4112 At the same time, moved obsavestring and obconcat to symtab.c.
4115 Removed obsolete condense_addl_misc_bunches (use
4116 condense_misc_bunches(1) instead).
4119 Needed to include <sys/dir>, at least on DECstations.
4121 valops.c, mips-tdep.c, tm-mips.h:
4122 Added PUSH_ARGUMENTS macro to support funny argument-pushing
4123 conventions (when STACK_ALIGN is insufficient).
4124 Needed on mips, where doubles need 8-byte alignment,
4125 but ints only need 4.
4128 Removed cruft that was not being used.
4129 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
4132 Print $ before register-names (I think that makes things a little
4134 Never print two instructions, even if one delays.
4135 Removed hex-disassemble set_cmd. (This is not mips-specific,
4136 so I think the argument is whether it is generally worthwhile or not.
4137 I'm inclined to think not, given how easy it is to
4138 convert between radixes in gdb.)
4141 This is basically Alessando's code.
4142 It doesn't use obstacks; I changed it to use obstacks
4143 in a few minor places where using malloc causes a
4144 memory leak. (Probably, more places could/should be changed.)
4145 I added record_misc_function where it was missing.
4146 In symbol_file_command and add_file_command, I tried
4147 to make the code consistent with more recent versions.
4148 Minor sylistic changes in parse_procedure.
4149 Make a .gdbinfo. psuedo-symbol point back to the real
4150 procedure symbol (using the isym field).
4153 This is basically from my port, but with a lot of details
4154 and a number of routines merged in from Alessando's version.
4155 I basically used my code "raw" backtrace (use heuristics
4156 from the actual code, rather than symbol table info) - though
4157 the idea is Alessandro's. I feel my code is a little cleaner
4158 here, particularly in being a little more flexible, such as being
4159 able to handle gcc-produced code (which it now can).
4160 It also doesn't do frame caching (which is not useful
4161 more recent gdb versions).
4162 I also used my code for push_/pop_dummy, more or less.
4163 I tried to incorporate AF's code for testing sigtramp
4164 while backtracing; I probably got it wrong.
4165 Added mips_print_register, which tries to scrunch as much
4166 information as possible on a screen...
4167 Removed the skip-prologue set_cmd. As with hex-disassemble (see
4168 under mips-pinsn.c), I don't see anything mips-specific here,
4169 and I don't see it being all that useful anyway.
4172 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
4173 Use more register names (rather than hard-cases numbers).
4175 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
4177 * Hack up 3.90.11 changes:
4179 * Makefile.dist (depend): parameterize $(GCC).
4180 Add solib.c and solib.o.
4181 (readline): Fix vpath for both absolute or relative SRCDIR.
4183 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
4184 Also, let the part I didn't understand at least compile so
4185 I can test the rest. FIXME.
4187 * dbxread.c: Fix thinko using strcmp.
4188 (init_psymbol_list): declare static.
4189 (partial_symbol_file_open): Comment cleanups better, avoid
4190 cleaning up the string table since the caller will do that.
4191 Move the stat for mod time into symbol_file_command, temporarily.
4192 (There should be a mod time for each symbol file, eventually,
4193 to control its rereading. FIXME.)
4195 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
4196 SunOS, which gives error for shared libs otherwise. (From
4197 Schaefer, probably FIXME needs work for portability.)
4199 * solib.c: Move #include "param.h" to work.
4200 Lowercase all the Uppercase Letters In the Messages.
4201 (find_solib): Clean up inferior_so_name for debug printouts.
4202 Allow no argument, to mean all shared libraries.
4204 * symmisc.c: include param.h to get CLEAR_SOLIB.
4206 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
4208 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
4209 to 3.90.11. ChangeLog entries below are from this.
4211 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4215 * Makefile.dist (HFILES): Add tm-sunos.h.
4217 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4221 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
4223 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
4225 * sparc-opcode.h Added single-operand version of rett.
4227 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4229 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
4230 Put parens around gcc_p in expansion.
4232 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4234 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
4236 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4238 * Changes for Sun shared libraries:
4239 blockframe.c (find_pc_partial_function): If a non-text symbol
4240 is found, set *address = pc - FUNCTION_START_OFFSET.
4241 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
4242 Disable breakpoints instead of giving an error.
4243 source.c (select_source_symtab): Initialize cs_pst.
4244 symmisc.c: Call CLEAR_SOLIB if defined.
4245 symtab.h: Make text{low,high} CORE_ADDR not int.
4246 (psymtab): New field addr.
4248 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
4249 (record_misc_function): Give correct type for N_DATA symbols.
4250 (condense_misc_bunches): do "misc_function_count = j" regardless
4252 Take code which is shared between symbol_file_command and
4253 add_file_command and put it into partial_symbol_file_{open,read}.
4254 Split add_file_command into add_file_command and add_file.
4255 Make psymtab_to_symtab read in the string table if the file
4257 Two new parameters to read_dbx_symtab and start_psymtab.
4258 tm-sunos.h: New file.
4260 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4262 * infcmd.c: Change cont_command to continue_command and "cont"
4265 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4267 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
4269 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
4271 * values.c (USE_STRUCT_CONVENTION): Check for structures of
4272 size 1,2,4,8 rather than size < 8.
4274 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
4275 as necessary, not just once.
4277 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
4279 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4281 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
4283 * tm-news.h: Add CALL_DUMMY_*.
4285 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
4287 * config.gdb: In list_host, list_target, use ${i}, not $i.
4289 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4291 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
4293 * sparc-opcode.h: Change all store floating-point state register
4294 instructions to have the right match & lose fields.
4296 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4298 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
4300 config.gdb: If srcdir != ., create readline directory and
4301 copy a makefile into it.
4303 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
4304 consistency with POSIX.
4306 * breakpoint.c (bpstat_stop_status): Disable watchpoint
4307 when we exit its exp_valid_block.
4309 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
4311 * Makefile.dist: Bump version to 3.91.3.
4313 * Clean up handling of breakpoint commands (somewhat).
4314 Prompted by Tiemann bug report "cont 10" doesn't work any more.
4316 inferior.h: Add breakpoint_proceeded to inferior status struct
4317 and globals; save it and restore it.
4318 (clear_breakpoint_commands): Cleanup, remove old #define.
4320 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
4321 (save_inferior_status, restore_inferior_status): handle it also.
4322 (proceed): Remove earlier code that set breakpoint_proceeded.
4323 It is now set only in clear_proceed_status.
4324 (clear_proceed_status): Cleanup, use bpstat_clear rather
4325 than clear_breakpoint_commands. No callers need the stop_bpstat
4326 between clear_proceed_status and proceed.
4328 infcmd.c: Add breakpoint_proceeded definition and comment.
4329 (cont_command, jump_command, signal_command): Move call to
4330 clear_proceed_status right next to call to proceed.
4332 breakpoint.c (bpstat_do_actions): Avoid clobbering our
4333 caller's argument while running down the chain of breakpoints.
4334 Use new variable "breakpoint_proceeded" to determine when
4335 a command that it executes moves the inferior past the
4337 (bpstat_clear): Handle NULL argument.
4338 (bpstat_clear_actions): Avoid useless call to
4339 breakpoint_auto_delete.
4340 (delete_breakpoint): Clean up bpstat's that are pointing to
4341 the deleted breakpoint from the stop_bpstat chain.
4342 (breakpoint_auto_delete): Simplify.
4344 * Clean up handling of EOF, error on stdin, etc. This was
4345 prompted by a network problem that caused gdb to go into an
4346 infinite loop filling up its malloc'd memory.
4348 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
4349 not clear_breakpoints_commands, which is now gone.
4350 (main): If command_loop returns (e.g. from EOF on stdin), do
4351 a quit_command (looping back to command_loop if quit_command
4352 doesn't really quit).
4353 (command_loop): check result from command_line_input and
4354 exit if it returns NULL, rather than passing the NULL to
4356 (gdb_readline): Free malloc'd result space before returning
4359 * utils.c (query): Handle C-d to mean "yes", just as if the
4360 input was not a terminal. Also avoid infinite loop if EOF
4361 occurs in mid-input-line before newline. This allows
4362 query to be used at EOF on stdin with reasonable results.
4364 * infrun.c (proceed): Set breakpoint_proceeded.
4366 * values.c (value_as_long): Avoid infinite recursion for enums.
4367 (_initialize_values): Fix typo in help msg (kingdon).
4369 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
4370 RL_LIB for linking. This allows -lreadline for linking
4371 and nothing for dependencies, once readline is a real library.
4373 * config.gdb: Jim Kingdon: give useful error message if the
4374 host or target type is not recognized.
4376 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
4377 it just defines it. Dumb, but deal with it.
4379 * Jim Kingdon suggests:
4380 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
4382 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
4384 * Makefile.dist (VERSION): Bump version # to 3.91.2.
4386 * Clean up Bothner's changes.
4388 * blockframe.c (clear_pc_function_cache): New function.
4389 * blockframe.c: remake cache_pc_function_* static.
4390 * dbxread.c (symbol_file_command): remove references to
4391 cache_pc_function_* variables.
4392 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
4393 * printcmd.c: Avoid kludging a global variable (addressprint)
4394 to avoid printing the address of a string twice. Instead,
4395 pass the format letter 's' down low enough that it can be seen
4396 to avoid this problem.
4397 (print_formatted): Pass format arg to value_print.
4398 (restore_addressprint): Remove function.
4399 (do_examine): Avoid hacking addressprint, cleanups and such.
4400 (print_frame_args): Add a comment to a Bothner change.
4401 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
4402 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
4403 to wipe out the values cached in blockframe.c.
4404 * symtab.c (find_method): Add comment saying how big you must
4405 allocate to be "big enough". Per being terse again.
4406 * valprint.c (val_print): Handle format letter "s" to print
4407 strings without addresses. Add comment to vtbl printing code
4408 which casts with wild abandon. Rearrange reference-printing
4410 @0xaddr: value (print w/addressprint)
4411 value (print w/~addressprint)
4412 @0xaddr (parameter lists w/addressprint)
4413 or nothing (parameter lists w/o addressprint)
4415 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
4417 * Merge more changes from Per Bothner:
4419 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
4420 annoying) that I tried to improve it. Here are my suggestions.
4422 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
4425 Do automatic de-reference when taking the address of a reference.
4427 Don't deref_ref when printing parameter lists.
4429 More attempts at treating refernences properly.
4431 In val_print, if deref_ref==0, don't print dangling " = ".
4433 Add COERCE_REF macro, which de-references an REF.
4435 * Merge changes from Per Bothner:
4437 * Fixed (Sony news)-specific configuration problems.
4438 * Fixed other problems with using vanilla pcc and libc (enum problems;
4439 assumption that vsprintf exists).
4440 * Some major speed-ups (finc_pc_partial_function now caches a match;
4441 parsing avoids duplicate symbol_lookup calls).
4442 * Changed handling of baseclasses (no longer use baseclasses field
4443 of struct type, use the first n_baseclasses fields instead).
4444 * Various minor changes/fixes, most C++-related.
4447 Cache the most previous match from find_pc_partial_function.
4448 (Save both low and high ends of matching function's pc range.)
4449 This speeds up the loop of infrun.c:wait_for_inferior quite
4450 a bit, and makes step/next commands much zippier.
4452 Added an enum->int cast (otherwise, some compilers barf).
4454 No longer set baseclass offset to 0, since multiple
4455 inheritance now mostly works.
4456 Added a number of casts, to shut up compiler warnings
4457 (after stabs where made enums, not ints).
4458 When discarding a symbol table (in symbol_file_command),
4459 must clear the cache introduced in blockframe.c.
4460 Don't convert $vtbl_ptr_type to vtbl any more.
4461 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
4462 Mask off sign bit emitted by g++ for virtual table offset.
4463 Set voffset to -1 (not 1) for static member functions.
4465 Changed parsing/lexing of names to avoid doing symbol lookup twice
4466 (once when lexing to determine symbol class, once for real).
4467 Now only call symbol_lookup once. Fields of 'this' win especially big.
4469 Subpress printing addr twice in the case of 'x/s addr'.
4471 lookup_basetype_type is no longer used.
4472 Add find_methods as recursive helper function to decode_line_1.
4473 This allows multiple inheritance to work.
4474 Also, once one or more matches has been found, do not look in
4475 base-classes. (Baseclass methods would be overridden, anyway.)
4477 Removed baseclasses array in struct type.
4478 Instead of using baseclasses[i], use fields[i-1].
4479 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
4480 Changed sign convention of voffset (previous was inconsistent).
4482 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4484 Used to assume existence of vsprintf. Re-written to not need it
4485 if HAVE_VPRINTF is undefined.
4487 typecmp was too pessimistic. Made it less so.
4489 Don't print space after address.
4490 If vtable points to a misc symbol (with 0 offset), print it,
4491 since that indicates the actual class of the object.
4492 Changed ype_print_derivation_info to use new inheritance
4493 scheme (without baseclasses vector).
4495 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4496 Also, changes needed because TYPE_BASECLASSES were removed.
4498 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4500 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4503 If there is no path set, and the symbols don't indicate what directory
4504 a file was compiled in, look in the current directory. But either
4505 a path or a known compilation directory will prevent this.
4508 Three independent bug fixes:
4509 * Remove the #if 0 block that breaks some stuff.
4510 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4511 adapt gdb to either SunOS 4.0.* or 4.1.
4512 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4515 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4518 (type_print) Demangle the name being printed.
4519 (type_print_base) Handle botched demangling without coredump (tiemann).
4522 (check_stub_method): Document routine.
4523 (tiemann) fix bug for no-arg functions
4524 Avoid clobbering beyond end of malloc'd storage.
4525 Terminate the argument list properly.
4527 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4529 * Changes merged by John Gilmore:
4532 In breakpoint_1, use new print_address_symbolic instead
4533 of find_pc_partial_function. (This forces use of assembler-level
4534 addresses, and avoids misleading non-mangled source-level names.)
4536 Generalize ansi argument such that -1 means skip arglist totally.
4537 Removed global variable print_ansi_qualifiers (which made
4538 code non-reentrant), in favor of extra explicit arguments
4539 to internal routines.
4541 Add new helper function print_address_symbolic.
4542 Use find_pc_misc_function instead of find_pc_partial_function
4543 (since we want assembler-level symbols here).
4545 Print unknown function as just "f (...)", not "f (...) (...)".
4546 Use new fputs_demangled explicitly.
4548 Fixed a typing violation (problem: value.h cannot be imported
4549 without renaming many variable in this file).
4550 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4551 decode_line_1: Moved forward some never-reached code.
4552 Made decode_line_2 skip function prologues correctly.
4554 fputs_filtered should not demangle by default.
4555 Add new fputs_demangled to demangle on demand..
4557 Change value_struct_elt to use value_primitive_field (using recursive
4558 utility function search_struct_field). This allows foo.bar to work
4559 for multiple inheritance (so far only for data fields).
4560 Change check_field in the same way (recursive helper function
4561 to support multiple inheritance).
4562 (Note: there are more of these problems that I haven't fixed.
4563 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4564 value_of_this: 'this' symbol name is now just "this", note "$this".
4566 Don't print static members.
4567 Avoid printing "members of <type>" if there are none.
4568 Simplified type_print_derivation_info by merging duplicate code.
4569 Remove useless blank lines in type_print_base (ptype command).
4571 Added declaration of new routine value_primitive_field.
4573 Added value_primitive_field which is generalized version of
4574 value_field that can handle multiple inheritance (non-zero offsets etc).
4575 Re-implemented value_field to call value_primitive_field.
4577 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
4579 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4580 delete the whole environment. Karl Berry reported the bug.
4581 * source.c - fix openp to avoid //'s in filenames, which
4582 trigger an Emacs bug causing it to not be able to find files
4583 when running gdb in a window.
4584 * dbxread.c - zap the #if 0 that botches the add-file code.
4585 It seems to work a lot better without all the code commented out.
4587 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
4589 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
4592 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
4594 * Makefile - added a ${CFLAGS} to a couple of entries,
4595 added remote-sa.sparc.c
4596 * added remote.sa-sparc.c, a modification of remote.c
4597 which conducts a dialog directly with the SparcStation prom.
4598 * breakpoint.c, infrun.c, sparcdep.c added
4599 remote_insert_breakpoint(), and remote_remove_breakpoint()
4600 to breakpoint.c instead of directly writing breakpoint instructions.
4601 * sparcdep.c on remote_debugging,there is no need
4602 to remove signle step breakpoint instructions.
4603 * main.c added "-epoch" flag and "int epoch_interface" to main.c
4605 * printcmd.c - epoch interface sends lisp expressions to open up
4606 epoch windows on inspection.
4607 * valprint.c - added arrayprint, and addressprint and made adding
4608 format controls easier
4609 * wait.h added a couple of undef's because we were getting
4610 complaints about WSTOPSIG and WTERMSIG begin redefined.

4680 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
4681 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
4682 when printing the type.

4706 step_resume_break_address != NULL, even if another_trap.
4707 If trap_expected and we enter sigtramp, then set up a
4709 If trap_expected is set when we hit the step_resume_break,
