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

1468 * source.c: Rename directories_info to show_directories.
1469 (_initialize_values): Rename "info directories" to "show directories".
1471 * values.c: Rename convenience_info to show_convenience.
1472 (_initialize_values): Rename "info convenience" to "show convenience".
1474 * copying.awk (_initialize_copying): Rename "info copying" to
1475 "show copying" and "info warranty" to "show warranty".
1476 Rename {copying,warranty}_info to show_{copying,warranty}.
1478 * symfile.c: Rename add_syms_command to add_symbol_file_command.
1479 (_initialize_symfile, add_syms_addr_command):
1480 Rename add-syms to add-symbol-file.
1482 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
1484 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
1485 * symfile.c (clear_symtab_users_once, cashier_psymtab,
1486 free_named_symtabs): Move these routines from symmisc.c.
1487 * symmisc.c (same): same.
1488 (free_symtab): Make non-static.
1489 * symtab.h (free_symtab): Declare as exported void fn now.
1490 * dbxread.c (end_symtab, end_psymtab): Change comments.
1491 (initialize_dbxread): Call dbx_new_init() in case the first
1492 command is add-symbols.
1493 * target.c (dummy_target): Permit add_syms_addr_command.
1495 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1497 Permit symbols to be superseded when new symbol files have
1498 been read in, particularly for VxWorks.
1500 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
1501 to the main file, as well as to include files. Also, put global
1502 functions into the global psymtab, to make "i fun" work.
1503 (end_psymtab): Free named symtabs and psymtabs for a file, once a
1504 new psymtab for it has been read.
1505 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
1506 a file, once a new symtab has been read for it.
1507 * mipsread.c: FIXME. We need to do the same for MIPS, but it
1508 looks harder to determine the top-level block before it's been
1509 queued to the psymtab list.
1511 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
1512 If we have wiped out any old symbol tables, clean up at end of
1514 (symbol_file_command): Don't reference symfile_fns if it's zero.
1516 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
1517 defines for the blocks of a blockvector that contain global and
1518 file-static symbols and the first of the smaller scope contours.
1519 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
1520 decode_line_1, make_symbol_completion_list): Use the above.
1521 * coffread.c (end_symtab, patch_opaque_types): Ditto.
1522 * dbxread.c (end_symtab): Ditto.
1523 * expread.y (block): Ditto.
1524 * mipsread.c (throughout): Ditto.
1525 * symmisc.c (free_named_symtabs): Ditto.
1527 * symtab.c (list_symbols): Process the first symbol of the
1528 static psymbols list.
1529 (types_info): Restore this function from its untimely #if 0.
1530 It's not perfect, but it is better than nothing.
1531 (_initialize_symtab): Restore "info types".
1533 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1535 * m68k-stub.c: Remote stub for 680x0's, created from
1536 rem-m68k.shar (which is removed).
1537 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
1538 Remove RCS log stuff now that we use CVS and it blows our diffs.
1540 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1542 * symmisc.c (free_named_symtab): Make it work, in its current
1543 kludgy fashion. Change result to indicate if we blew away bkpts.
1544 * dbxread.c (end_symtab): Accumulate result from
1545 free_named_symtab and print warning if we blew user's state.
1546 * symfile.h: free_named_symtab now returns an int.
1548 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1550 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
1551 is the first symbol read, even if not mainline.
1552 (dbx_psymtab_to_symtab): symfile might be zero, cope.
1553 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1554 (set_section_command): New command ("section xxx yyy" -- should
1555 be renamed to "set section xxx yyy" FIXME) which sets the
1556 base address of a section of the exec file, overriding the
1557 virtual address that BFD reports.
1559 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1561 * exec.c: Add add_syms_addr_command to exec_ops, so you can
1562 load symbols at any address while examining an exec file.
1564 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1566 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1567 for printing the float info is host-dependent, not
1568 target-dependent. FIXME.
1569 * i386-pinsn.c: Move #includes to top, remove useless ones.
1570 * i386-tdep.c: Don't bother including <.../reg.h> since we
1571 don't use it (and it doesn't exist on host systems).
1573 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1574 Convert negative numbers properly.
1575 (ieee_test): Make numbers really random; fix format arg.
1577 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1578 * core.c (core_detach): Unpush core_ops, which might not be on
1579 top. We used to just pop the top, which broke things. Don't
1580 need dont_repeat() any more.
1581 (core_file_command): Psst! Don't repeat it.
1582 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1583 * expprint.c (print_subexp): Avoid switch fallthru on
1584 BINOP_ASSIGN_MODIFY, so we can print += and such.
1585 * frame.h: Fix typo.
1586 * inflow.c (kill_command): After killing inferior, print our
1587 current frame in the core file, if we have one.
1588 (generic_mourn_inferior): When inferior dies, either select
1589 the current frame (in the new target, e.g. core file), or
1590 set both the current and selected frames to NULL.
1592 Changes from Peter Schauer.
1594 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1596 * Make all file names fit in 14 characters (sigh and damn!):
1597 mv hp300hpux-xdep.c hp300ux-xdep.c
1598 mv symmetry-xdep.c symm-xdep.c
1599 mv symmetry-tdep.c symm-tdep.c
1600 mv convex-opcode.h convx-opcode.h
1601 mv tm-vxworks960.h tm-vx960.h
1602 mv tm-vxworks68.h tm-vx68.h
1603 mv Makefile.srcdir Makefile.sdir
1604 mv gdb-int.texinfo gdbint.texinfo
1605 mv remote-sa.m68k.shar rem-m68k.shar
1606 mv remote-multi.shar rem-multi.shar
1607 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1608 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1609 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1612 * command.c (user_info_1, user_info): New command for listing
1613 the user-defined commands.
1615 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1617 * dbxread.c (really_free_pendings): Clear file_symbols
1618 and global_symbols after freeing them; otherwise, running
1619 this function twice (if it appears twice on the cleanup
1620 chain), we try to free things twice.
1622 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1623 based on text_addr (the address of text in core), not on addr (the
1624 offset between text in the .o file and in core). This change
1625 is from Peter Schauer.
1627 * main.c: Define ALL_CLEANUPS as a cast of zero.
1628 (return_to_top_level): Use it.
1629 (main): Do all cleanups after each command run as part
1630 of the gdb startup sequence. Also do all cleanups before
1631 entering the command loop, and every time we exit the command
1632 loop and reenter. Before, the cleanups from the startup sequence
1633 were being left undone until the first error!
1634 (command_loop): Rename do_nothing cleanup to command_loop_marker
1635 so we can see it easily when examining the cleanup chain.
1636 (init_signals): Add another do_nothing for signal handling.
1637 (quit_command): Only try to kill target if it has execution.
1638 Problems in the target stack got us into a state where
1639 inferior_pid was nonzero but none of the targets had execution.
1640 In this state you couldn't exit gdb.
1642 * dbxread.c: Two changes from Peter Schauer.
1643 (echo_command): Fflush output after an echo command.
1644 (show_history): Pass all args to cmd_show_list.
1646 * utils.c (init_malloc): Call mtrace to turn on tracing
1647 if the environment variable MALLOC_TRACE is set to a file name.
1648 * mtrace.c: Add source file which provides a log of every malloc,
1649 free, and realloc to a trace file.
1650 * mtrace.awk: Add source file which analyzes the trace file.
1651 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1652 (VERSION): Roll to 3.94.3.
1654 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1655 (check_duplicates): Don't bother with watchpoints.
1656 (set_raw_breakpoint): Comment about danger of this routine.
1657 (watch_command): Parse and eval all args before calling
1660 * solib.c (find_solib): Avoid error in referencing memory to
1661 see if any more shared libraries have been added. This is
1662 particularly useful if the target has terminated. Bug reported
1665 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1666 in bringing up 3.94.2 on the Sun-3.
1668 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1669 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1670 expression (in scope) before reenabling watchpoint.
1671 * signame.c (init_sigs): Add missing declaration of i, fix
1672 sys_siglist declaration.
1673 * source.c (list_command): Fixed range computation to use
1675 * stack.c (backtrace_command): Do not allow command if target has
1676 no stack, print informative error message.
1677 * target.c (target_command): Do not write into command line
1678 because this fails if the target command is used in a user defined
1679 command. [This change was enhanced by gnu to support any-
1680 unique-prefix matching on target names.]
1681 * valops.c (value_struct_elt): Avoid infinite loop on an
1682 erroneous attempt to print the member of function (try p main.p).
1684 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1686 * expread.y (name_no_typename): Avoid reduce/reduce errors
1687 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1688 Since the GDB parser really doesn't use name_no_typename in a
1689 name-only context, the parser can't tell the diff between
1690 names and numbers here. Avoid allowing a name_no_typename
1691 to be a NAME_OR_*INT to resolve the conflict.
1693 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1695 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1697 * valprint.c (val_print_fields): bitfield printing didn't handle
1698 byte order. Indirect through a few more fns to cope.
1700 * values.c (modify_field): also cope with byte order.
1702 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1704 Cleanup for release 3.94.2:
1706 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1707 include files. Roll version to 3.94.2.
1709 * coffread.c (init_stringtab): Read length into unsigned char
1710 array before swapping; don't assume 32-bit longs.
1712 * target.c (target_info): Don't bother with get_sym_file, just use
1713 the symfile global variable.
1714 * symtab.h, symfile.c (get_sym_file): Delete it.
1716 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1717 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1718 (read_type): Replace one more error() with complain().
1720 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1722 * i960-tdep.c: Fix copyright attribution.
1724 * config.gdb: Quote all backquotes in doublequotes. You can
1725 quote me on that. BSD 4.4 shell found this one.
1727 * infptrace.c (throughout): The third argument to ptrace is an
1730 * infrun.c (wait_for_inferior): When program has terminated, we
1731 have to call target_terminal_ours before we pop that target off
1732 the stack (e.g. before a call to target_kill or
1733 target_mourn_inferior). This fixes problem where a program
1734 terminates, then GDB stops for (tty output) and you have to type
1735 "fg" to the shell to resume it. FIXME: This code for what to
1736 do after termination really should be in normal_stop instead.
1738 * gdbcore.h (read_memory_check): Change declaration; it changed
1741 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1742 4.4 prereleases, this avoids a bug in their sgtty compatability
1744 * remote.c: Use terminal.h rather than hand-rolling the same.
1746 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1747 * utils.c (strsave, strstr): Fix arg types.
1748 * valprint.c (val_print): lint
1750 MIPS symbol table support from Per Bothner:
1752 * symfile.c (symtab_fns): Remove initializer table that needs to
1753 be hacked for each new symbol file format supported.
1754 (add_symtab_fns): New function, chains symbol table
1755 handlers into the global list.
1756 (symfile_init): Search this list.
1757 * symfile.h: Add next pointer, declare add_symtab_fns.
1758 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1759 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1761 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1762 symbol *). Thus, we no longer need the hack to trash
1763 pst->filename. Good, since that hack confused code in symfile.c!
1765 (reorder_symtabs, destroy_all_symtabs): Removed static
1766 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1767 Instead, the latter now uses a temporary array (stack-allocated
1768 from an obstack, and then freed).
1770 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1771 haven't been set in the outermost stBlock of a procedure. This was
1772 a problem with f77 binaries on Ultrix 4.?.
1774 (new_symtab, new_symbol, new_type): Continue changing code to use
1775 obstacks more and otherwise conform to dbxread internal style.
1776 Made the free_code of symtabs be free_linetable (as in dbxread)
1777 instead of free_contents. This implies memory leaks when reading
1778 a new symbol table, until the conversion is finished. Did change
1779 (struct symbol) and (struct type) to be allocated on the
1780 symbol_obstack. Blocks and blockvectors are among the things
1783 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1784 tested much, but it solved one problem (reported by Meissner), and
1785 cleans up some other things. The problem happened when an
1786 included file contains actual code (functions) and not just
1787 definitions. The mips coff is a little inconvenient there, since
1788 it may cause a procedure to be mapped to the wrong psymtab.
1790 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1791 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1792 this will need work for the new core paradigm.
1794 Opcode patches from the net:
1796 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1797 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1798 missing altogether - they are added here. From Bruce Bauman.
1799 * mips-opcode.h: The low mask for C0 instructions was too small.
1800 From Garrett Lau. I modified the fix to check the entire 32-bit
1803 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1806 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1808 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1810 * dbxread.c (read_type): Pointer subtraction (value_sub in
1811 valarith.c) sometimes failed because the types of the
1812 pointers being subtracted were not identical.
1813 These differed because dbxread.c was allocating pointer types
1814 using dbx_alloc_type+smash_to_pointer_type instead of
1815 lookup_pointer_type. I failed to find a justification for the
1816 former, so I changed it to use the latter. Similarly, I
1817 replaced smash_to_function_type by lookup_function_type,
1818 and smash_to_reference_type by lookup_reference_type.
1820 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1821 _initialize_mipsread): corresponding changes.
1823 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1825 * source.c (mod_path): Do tilde_expand on each component of the path,
1826 rather than on the (list of) paths as a whole.
1827 (print_source_lines): Set first_line_listed in addition to
1828 current_source_symtab and current_source_line. If the source was
1829 not findable, after a "dir" command to fix the problem,
1830 a "list" would get the wrong lines.
1832 While I was there... (gnu):
1834 * dbxread.c (read_type): Change error to complaint.
1836 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1838 First attempt at detailed understanding of symbol table memory alloc.
1840 * dbxread.c (dbx_symfile_read): Free our string table if we
1841 aren't the mainline. Free the "info" struct since we're done with
1843 (init_psymbol_list): Free any previously allocated psymbol lists.
1844 (): FIXME: Should realloc-down the psymbol lists when done reading
1845 the main symbol file?
1847 * symmisc.c (free_symtab): Free fullname field too.
1849 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1850 (REGISTER_ADDR): Make result type unsigned int.
1852 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1853 define REGEX must also define REGEX1 (its dependency).
1855 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1857 * tconfig/i960: No longer works, points you at vxworks960 or
1860 * xgdb.c, XGDB-README: Remove file. Users can get the much
1862 * Makefile.dist: Remove all trace of xgdb.
1864 * breakpoint.c (breakpoint_1): Pass demangle arg to
1865 print_address_symbolic.
1866 (clear_breakpoints): Remove unused function.
1867 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1868 (breakpoint_re_set): Use catch_errors to do them all anyway.
1870 * gdb-int.texinfo (Host versus Target): Add section on what is
1871 a "host" feature versus what is a "target" feature.
1873 * infcmd.c (path_command, path_info): Handle the PATH variable
1874 (object search path) as conveniently as the source search path.
1875 * environ.c (set_in_environ): Set some vars in GDB's environment,
1876 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1877 * source.c (mod_path): New function, from guts of
1878 directory_command, modifies a path. Used by path_command.
1879 (directory_command): Call it.
1880 * defs.h (strsave): Declare.
1882 * utils.c (sevenbit_strings): Add new printing option.
1883 (printchar): Use it.
1884 (strsave): Provide this handy helper routine.
1885 (set_width_command): Rename set_screen_width_command.
1886 (_initialize_utils): "set screen-width" => "set width";
1887 "set screen-height" => "set height"; add sevenbit-strings.
1889 * infcmd.c (do_registers_info): Print floating point registers
1890 in raw hex as well as float format, regardless of whether it is
1891 a "virtual" convertible register.
1892 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1893 regs as a double, just in case it's being used that way.
1894 * values.c (unpack_long): Comment on array/function coercion.
1895 (unpack_double): Argument is in target byte order now. For
1896 integer arguments, just call unpack_long and float the result.
1897 * m68k-tdep.c: include defs.h for "const" handling.
1898 * remote-nindy.c: Use ieee-float stuff.
1899 (nindy_fetch_registers): Unpack double regs to host double, then
1901 (nindy_store_registers): Pack extendeds to host double, flip
1902 around by misusing unpack_double, send as target double.
1904 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1905 zero, as when stopped at the first instruction of a process.
1907 * blockframe.c: Fix filename in comment (param.h => tm.h).
1908 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1909 * tm-68k.h: Fix typos.
1911 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1913 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1915 * coredep.c (fetch_core_registers): Pass end-address of register
1916 section to register_addr as expected. Don't call supply_register
1917 if we'd just pass it garbage.
1919 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1921 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1923 * target.c (push_target, target_info): Cast enums to int for < or
1926 * stack.c (print_frame_info): Identify source file & line
1927 even if we can't print it.
1929 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1931 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1933 Clean up IEEE floating point support.
1935 * ieee-float.h: New file.
1936 * ieee-float.c: Write real routines to convert between host
1937 doubles and various target IEEE extendeds.

1941 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1942 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1943 double_to_ieee_extended.

1945 * m68k-tdep.c: Define ext_format_68881.
1946 * sparc-tdep.c: Define ext_format_sparc, though unused.
1947 * Makefile.dist (HFILES): Add ieee-float.h.
1948 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1951 Obsolete the "coffstrip" program in favor of using BFD's strip.
1953 * nindy-share/coffstrip.c: Remove file.
1954 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1955 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1956 * tconfig/nindy960: Remove reference to coffstrip.o.
1958 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1960 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1962 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1963 * dbxread.c: Remove static symfile_bfd.
1964 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1966 * inftarg.c (child_detach): Pop the child_ops vector if the
1967 detach is successful.
1968 * remote-nindy.c (nindy_create_inferior): Don't push a new
1969 nindy_ops since nindy uses the same one for execution and memory
1971 * core.c (core_ops): Use child_attach and child_create_inferior
1972 rather than default attach and create_inferior functions.
1974 Handle floating point registers in core files.
1976 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1977 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1978 This version untested since BFD doesn't yet support sun3 core
1980 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1981 conventions. Fix comments and style. This version has not
1982 been compiled yet, since we have no HP inhouse.
1983 * core.c (get_core_registers): Look for two sections, ".reg"
1984 and ".reg2", and pass both to fetch_core_registers sequentially.
1986 Revise directory path yet again.
1988 * source.c (forget_cached_source_info): Not static any more.
1989 (init_source_path): New default source path is "$cdir:$cwd".
1990 (dir_command): Handle variable arguments ($cdir, $cwd).
1991 (source_info): Print "Compilation directory" rather than
1992 "Originally compiled in" to remind people of $cdir.
1993 (openp): If the path contains $cwd, use current directory.
1994 (open_source_file): If compilation directory is known, replace
1995 first $cdir in path with the compilation directory.
1996 (print_source_lines): Even if we can't print the lines, set the
1997 current symtab and line for future commands like "info source" or
1998 "breakpoint". Also, error message now contains the file name,
1999 line number, and file access error message.
2000 (_initialize_source): Fix help text to describe changes.
2001 * main.c (cd_command): Forget cached source info when we chdir.
2002 * utils.c (strstr): Add simple implementation.

2006 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2007 Byte-swap COFF symbol tables if necessary when reading them in.
2008 Use complain() to replace error message in one spot. Needs
2009 corresponding change in bfd/coff-code.h to make some symbol
2010 swapping routines non-static.
2012 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2014 Merge changes from Eirik Fuller, for UTek.

2022 declarations of errno.
2024 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2026 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2027 <rpc/rpc.h> and <rpc/types.h>.
2029 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2031 * i960-tdep.c (examine_prologue): Add new argument limit,
2032 which stops the scan at the end of the prologue, or at the PC.
2033 This fixes a problem where it walks down into the code for the
2034 user's statements if that code looks like function prologues.
2035 Mark Fox and I have been bouncing this code back and forth, making
2036 small changes to it. Callers changed to match.
2038 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2040 Cleanup for gdb-3.94 release final:
2042 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2043 the .c files from vx-share and nindy-share, from the various
2044 macros, since they are not found via ALLDEPFILES.
2045 (SFILES): Add tm-i960.h.
2046 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2047 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2049 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2050 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

2054 * am29k-tdep.c: Add contribution line.
2055 (examine_prologue): Cache information about function prologues in
2056 the misc-function-vector to avoid lots of references over the
2057 serial line while examining instructions.
2059 * core.c (core_close): New function made from cleanup_core.
2061 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2062 remote-vx.c, remote.c, target.c, target.h,
2063 Update target_ops vector to add attach, close, and load entries.
2064 Use add_syms_addr_command, not add_file_addr_command, for
2065 add_file. Break out close routine from existing code.
2067 * dbxread.c (really_free_pendings): Don't free pending_blocks;
2068 they are in an obstack.
2069 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
2071 (define_symbol): Add symbol type parameter; change callers;
2072 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
2073 it to influence the symbol class on the i960.
2074 (define_symbol): Swap LOC_CONST's into target byte order.
2076 * exec.c (exec_close): New function.
2077 (exec_file_command): Call it.
2079 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
2080 Fix byte order of frame pointer.
2081 (read_var_value): Result of 0 if var's value can't be found,
2082 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
2083 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
2084 (locate_var_value): Use read_var_value and use its lazy address
2085 as the location of the var's value. Lint.
2087 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
2090 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
2091 obsolete Intel versions in favor of vxgdb versions.
2092 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
2093 code dealing with byte order of values, which Intel did in host byte
2094 order rather than gdb-4's target byte order.
2095 (i960_frame_chain_valid): Move to nindy-tdep.c.
2096 (examine_prologue, skip_prologue, frame_find_saved_regs,
2097 frame_args_address, leafproc_return, saved_pc_after_call,
2098 pop_frame): Add vxgdb versions from Mark Fox.
2099 (examine_prologue, frame_struct_result_address): Add code
2100 to deal with the saved value of G13 (struct return address
2102 (frame_args_address): Modify Mark's version to prefer the
2103 saved value over the current value in the topmost frame.
2104 Cache result in the frame info to avoid performance hair in
2106 (print_fault): Add gdb960 code for printing faults.
2107 (_initialize_i960): Actually call check_host.
2109 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
2110 add stub routines. FIXME, these currently just return zero!
2112 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
2113 (attach_command): Call target_attach, not target_open, now.
2115 * infrun.c (normal_stop): Make global, not static, for vx_attach.
2116 (child_attach): Rename from child_open.
2117 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
2118 don't confuse it with a zero step_resume_break_address.
2120 * inftarg.c (child_detach): Eliminate inferior_pid test.
2121 (child_files_info): Clean up message a bit.
2122 (child_ops): Use child_attach, not child_open, to attach.
2124 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
2125 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
2126 findvar.c to here, since it depends on the contents of the
2127 shadow_contents of breakpoints, but keep if #if 0 since it is
2130 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
2133 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
2134 (ptype_command, display_command): Eliminate have_inferior_p and
2135 have_core_file_p in favor of target_has_stack or
2136 target_has_execution.
2137 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
2138 code for actually finding the values of arguments, though we still
2139 keep track of the maximum stack offset for use in printing unnamed
2140 arguments. Handle missing FRAME_ARGS_ADDRESS.
2142 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
2143 (struct nindy_regs): Define registers passed to/from nindy.
2144 (nindy_fetch_registers, nindy_store-registers): Translate between
2145 nindy and GDB formats for the registers.
2146 (dcache_init): Statically allocate the cache, since it was being
2147 allocated by a malloc that was never freed anyway.
2148 (nindy_create_inferior): Error, not core dump, if no exec file.
2149 (nindy_before_main_loop): Use target_load, not target_add_file.
2151 * remote-vx.c (net_load): Specify large timeout for load
2152 requests. Allow user to break out with INTERRUPT.
2153 (net_break): Remove useless code, clean up. Change callers.
2154 (parse-args, skip_white_space, find_white_space): Clean up arg
2155 parsing to cope with quoted strings.
2156 (net_wait, net_quit): Never call error, just return status.
2157 (vx_read_register, vx_write_register): Cleanup status checking.
2158 #ifdef the code based on which CPU we are using (960 or 68k),
2159 FIXME, this should be completely general but it isn't yet.
2160 (vx_xfer_memory, vx_resume): Cleanup status checking.
2161 (vx_run_files_info): Improve message.
2162 (vx_load_command): Renamed from vx_add_file_command. Allow load
2164 (net_ptrace): Remove unused routine.
2165 (vx_wait): Adopt code from vxgdb960 to cope with broken
2166 connections to target machine and prompt to disconnect. Remove
2167 debug printouts. Map some EVENT_'s to SIGnals.
2168 (add_symbol_stub, vx_open): Print names of object files we found,
2169 and "ok" if we read their symbols OK. Clarify output in general.
2170 (vx_attach, vx_detach, vx_kill): Add these commands.
2171 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
2172 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
2173 "info files" output, and create_inferior, since we already have
2176 * stack.c (frame_info): Replace Frame_unknown with 0.
2177 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
2178 (return_command): Pop until the PC matches as well as the FP,
2179 so it works even if the FP is shared with another function,
2180 as in "frameless" or "leaf" procedures.
2182 * symfile.c (load_command): renamed from add_file_target_command.
2183 (add_syms_addr_command): renamed from add_file_addr_command.
2184 (add_syms_command): Stub to call target_add_syms.
2185 (_initialize_symfile): Change command names and descriptions,
2186 add-file => add-syms, and load from alias to its own command.
2188 * target.c (kill_or_be_killed, maybe_kill_then_attach,
2189 maybe_kill_then_create_inferior): Default for attempts to start
2190 a process, if one is already running, is to ask about killing
2191 it and retry if yes.
2192 (upstack_create_inferior): #if-0 it, strata obsolete it.
2193 (push_target, unpush_target, pop_target): to_close() a target
2194 before unstacking it.
2195 (target_info): Renamed from target_files_info.
2196 (_initialize_targets): Rename "i files" as "i target", accessible
2199 * target.h: Improve comments about the target_ vectored routines.
2201 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
2202 Convert commenting style to standard GNU style.
2203 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
2204 (SKIP_PROLOGUE): No longer a no-op.
2205 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
2206 (*_REGNUM): Sort register numbers.
2207 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
2208 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
2209 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
2210 are now 10 byte extendeds, not 8 byte doubles.
2211 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
2212 for nindy versus vxworks targets. FIXME, this should possibly go
2213 in the target vector.
2214 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
2215 frame_saved_regs and arg pointer with each frame.
2216 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
2217 (FRAME_ARGS_ADDRESS): Use cached result.
2218 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
2219 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
2220 (PRINT_RAMDON_SIGNAL): Call print_fault.
2221 (POP_FRAME): Now works.
2223 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
2224 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
2225 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
2226 (ADDITIONAL_OPTION_HANDLER): use target_load, not
2229 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
2230 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
2232 * valarith.c (value_subscripted_rvalue): Avoid handling
2233 floats and doubles specially; it gave alignment errors. Lint.
2235 * valops.c (value_of_variable, value_of_this): Error if unknown
2238 * valprint.c (print_floating): Bcopy rather than pointer-deref,
2239 to avoid alignment problems.
2240 (value_print): Handle unknown value address.
2241 (cplus_val_print): Two args are ignored; remove them. Change caller.
2242 (val_print): Use unpack_long rather than pointer-deref.
2245 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
2246 to avoid alignment problems.
2247 (value_being_returned): Error if return value unknown.
2248 (set_return_value): Add bogosity warning, FIXME. *
2250 * TODO: A woman's work is never done.
2252 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
2253 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
2254 Add ieee-float.o to OBS.
2255 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
2256 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
2257 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
2259 Changes to generalize the VxWorks RPC protocol slightly, to handle
2260 i960 as well as 68000.
2262 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
2263 * vx-share/reg.h: Produce i960 regs #ifdef I80960
2264 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
2265 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
2266 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
2267 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
2268 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
2269 so they will move in target byte order rather than network
2270 byte order (happens to be the same).
2272 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2274 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
2276 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2279 Add contribution lines to various files, showing where they
2282 * breakpoint.c (break_insn, check_break_insn_size,
2283 read_memory_nobpt): Remove to mem-break.c.
2285 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
2288 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
2289 entry has bad register number. This change is not
2290 tested in this release, FIXME.
2292 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
2295 * value.h: Force value's contents field to be aligned to hold
2296 at least a double or a long long (if supported). This avoids
2297 doing bcopy's in and out of the contents field.
2299 (step_1): Avoid coredump under obscure circumstances when we
2302 * symtab.h (misc_info): Add field to misc function vector for
2303 any kind of cached information the target code desires. AMD
2304 29000 uses this to avoid repeating examine_function_prologue's.
2306 * coffread.c: Lint. Remove static symfile, read_section_header.
2307 core.c (have_core_file_p): Lint: remove.
2308 expprint.c (print_subexp): Lint.
2309 infptrace.c, valops.c, valprint.c: lint.
2311 Roll in changes from vxgdb-5.0.1:
2313 * symtab.h: Comment byte order of each address class. Add
2314 LOC_LOCAL_ARG for frame-relative args (960).
2315 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
2316 symtab.c, symmisc.c: ditto.
2318 * infrun.c (init_wait_for_inferior): Clear stop_signal.
2320 * remote.c (remote_resume): Error if resume with a signal.
2322 * symfile.c (prim_record_misc_function): Clear misc_info.
2323 (fill_in_vptr_fieldno): Check stub type of arg.
2325 * valops.c (value_cast): Avoid looking up names of types whose
2326 name we don't know, to prevent coredump. Sun CC produces typedef
2327 rtx and the name of *rtx is zero...
2329 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2331 Roll in changes from final AMD 29000 port (Tiemann).
2333 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
2334 for ../include/a.out.encap.h. This might not work now that BFD
2335 is separately compiled. Instead, BFD support for encap will have
2336 to translate machine type 29k into the right COFF_MAGIC.
2338 * infcmd.c: Remove references to inferior_pid that aren't used
2339 in actual ptrace calls; use target_has_execution, etc.
2340 (have_inferior_p): Remove function.
2341 (program_info): Print target info rather than "process number";
2342 avoid gratuitous messages unless from_tty.
2343 (run_stack_dummy, finish_command): Set proceed_to_finish.
2344 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
2345 main.c: Lint. Lose have_inferior_p().
2346 inferior.h (have_inferior_p): Remove, lint.
2347 (proceed_to_finish): Add flag to ask that all regs be saved
2348 by normal_stop, for the few commands that need it, speeding up
2349 serial I/O. Add comments to stop_registers.
2351 * remote-eb.c: Remove newline from breakpoint message we grep
2352 for. Never time out when running the user program.
2356 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2358 Roll in changes from vxgdb-5.0.1:
2360 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
2361 symbol in its raw form, we are processing an unlinked ".o" file.
2362 See if the target environment has assigned it an address, using
2363 target_lookup_symbol (VxWorks does), and enter it into the symtab
2366 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
2367 68k versions for a simpler version that assumes zero FP at bottom.
2368 Fixes bug of truncated stack reports.
2370 * target.h (target_lookup_symbol): Define this routine's args
2371 and result, finally.
2373 * target.c (nosymbol): Default routine for target_lookup_symbol.
2374 (target_default): Default lookup_symbol and call_function too.
2375 (files_info): Only print has_all_memory warning if a non-dummy
2378 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
2379 vx_convert_from_virtual): If target does not have floating point,
2380 zero register "values", and avoid doing cross-net conversions.
2381 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
2382 (vx_open): Rearrange code that attaches to target and reads
2383 symbols for all loaded modules, to work if some of the modules
2384 are not accessible. Add symbol_stub() and add_symbol_stub()
2385 as callbacks from catch_errors(). Allow connect attempt to be
2386 interrupted painlessly with ^C (FIXME, there are still some bugs
2387 if the interrupt happens during symbol reading.). Print
2388 final message with puts_filtered, since symbol messages are
2393 * main.c (catch_errors): Only print errstring if non-null.
2394 (command_loop): Avoid an ioctl per command to test ISATTY.
2396 * remote-vx.c (net_load): make static; avoid sophomoric msg.
2397 (vx_xfer_memory): Return correct result!
2398 (vx_files_info): Indicate whether target has float or not.
2399 (vx_lookup_symbol): Complain, not error, if target gone.
2400 (vx_open): Print "Connected" msg before disabling immediate-quit.
2401 [FIXME: lookup_symbol and vx_open changes need testing.]
2403 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
2404 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
2405 contributor lines and update copyrights to 1991.
2407 Changes from an attempted H-PUX host port:
2409 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
2410 defines PT_ATTACH and PT_DETACH but not PT_KILL.
2411 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
2412 * remote-vx.c: include <sys/time.h> for HPUX.
2413 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
2414 "core_file_command" routine to BFD regime. May not work yet.
2416 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
2418 * xgdb.c: Replace X10 version with some VJ version.
2419 (FIXME: Its copyright assignment is not on record.)
2420 * xgdb.c: Update include files to X11R4 (Xaw crud).
2421 (xgdb_display_source, create_text_widget): fix call to
2422 get_filename_and_charpos. Rewack source window stuff for X11R4
2423 (gleaned from include files, and "nm's" of binary libraries, since
2424 I had no doc available).
2425 (append_selection, append_selection_word): Disable with FIXME
2426 since R4 changed interface here.
2427 (create_buttons): Add back the old set of buttons.
2428 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
2430 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
2431 Roll VERSION to 3.94 (not yet final though).
2433 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2435 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
2436 obstack_int_grow, obstack_int_grow_fast): Eliminate
2437 cast on left of assignment, which gives MIPS cc fits and is
2440 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
2441 F_ALIAS. Use printf, not fprintf, when not passing a file
2443 (compare_opcodes): Check that identical instructions have
2444 identical opcodes, complain otherwise.
2446 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
2447 was reported by Roland McGrath.
2448 (unimp): Only match if exactly zero instruction. (Roland)
2449 (branches and traps): Generate all variations of these
2450 instructions with macros, based on a single call that defines
2451 each condition name and its binary representation.
2452 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
2454 * valprint.c (val_print_fields): Take, and use, format parameter.
2455 This means that "p/x struct" again prints the elements in the
2456 desired format. Changed callers.
2458 * stack.c (frame_info): Use filtered output, and indicate wrap
2459 points. Remove kludgy formatting designed to avoid line wrap.
2461 * utils.c (wrap_here): If the line is already full (because
2462 we had printed a long indent or long wrapped string), do an
2463 immediate newline-and-indent.
2465 * m68k-pinsn.c (print_insn_arg): Bugfix from
2466 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
2467 instruction is incorrectly disassembled as bkpt #8.
2469 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
2470 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
2471 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
2472 and then will dump core (sometimes). I traced it back to an
2473 uninitialized symfile_name in psymtab_to_symtab.
2474 (const_vol_complaint): Add quotes to message.
2475 (define_symbol): Only believe line number if gcc_compiled.
2476 Avoid allocating symbol if we will not return it.
2478 Add target strata support so that newly established targets go
2479 into their right place in the target stack (e.g. a new exec file
2480 doesn't wipe out the ability to access the running process).
2482 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2483 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2484 and initialize it properly in all the targets.
2486 * target.h: Document strata. Change return type of push_target.
2488 * target.c (nomemory): new function for dummy memory access.
2489 (tcomplain): Rename complain, now also used in symfile.c.
2490 (push_target): Push targets within strata. New return value shows
2491 whether new target is on top of stack or not. Always keep dummy
2493 (target_files_info): Ignore dummy target.
2495 * core.c (core_open): Warn user, and skip accessing file, if the
2496 core target is not the topmost target in the stack.
2497 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2500 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2501 target_ops, it doesn't belong there since we have no regs there.
2502 Change name of target from machine => memory to clarify.
2504 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2506 * Freeze version 3.93 for release.
2508 * Makefile.dist: Handle vx-share and nindy-share subdirs
2509 properly when building gdb.tar.Z.
2511 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2512 printed in various places, so I could change just one copy.
2514 * dbxread.c, coffread.c: Change references to bfd->iostream
2515 to cast to FILE *, now that BFD avoids needing types defined
2516 in other header files.
2518 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2520 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2521 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2522 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2523 (actually gcc -Wall).
2525 * dbxread.c: Remove first_global_sym, last_global_sym, since
2526 they are never referenced.
2528 * defs.h (baud_rate): Declare.
2529 main.c: Define it, and add the -b option to set it.
2531 * gdb-int.texinfo: Add text on how to define a new host or target
2532 architecture, prompted by Per Bothner's questions about MIPS
2535 * gdb.texinfo: Document "complaints". Change doc of -q since
2536 gdb no longer prints the copyright and blurb if you specify a file
2537 name to be debugged (just like Emacs). Add doc for Nindy-specific
2538 command line flags for specifying target serial port and such.
2539 Update copyright to 1991.
2541 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2542 has taken over for us the job of ripping up executable files. The
2543 crud caused Per Bothner's port to not compile.
2545 * infrun.c (normal_stop): Avoid printing "Program exited
2546 normally" if we are in batch mode. This allows a GDB which
2547 executes a program on a target system, to behave like a Unix
2548 command (input from stdin, output to stdout, no extraneous
2551 * main.c (main): Allow additional machine-dependent command line
2552 options to be specified with the ADDITIONAL_OPTIONS,
2553 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2554 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2555 processing to occur just before the main loop with
2556 BEFORE_MAIN_LOOP_HOOK.
2557 (main): If a "core file" argument is specified, and it is not a
2558 core file, try it as a process ID to attach.
2559 (symbol_completion_function): Attempt to cope with
2560 "show screen-" TAB, not very successfully. This needs more work,
2562 (batch_file): New function, returns whether we are reading
2563 commands from an interactive tty on stdin, or from somewhere else.
2564 Called by normal_stop since it doesn't get from_tty passed down
2565 to it like many commands do.
2567 * remote-nindy.c: Handle command line options for nindy
2569 (nindy_before_main_loop): Prompt user for tty name if they
2570 don't specify it before getting to the interactive command loop.
2572 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2573 and -r command line options. Also add hook before main loop
2574 to make it easy to specify a tty.
2576 * TODO: More things to do, one done.
2578 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2580 * dbxread.c: Make complaint() calls pass pointer, not struct.
2581 Add complaints about badly formatted C++ type information
2582 (const/volatile indicator, and parse errors resulting in
2583 error_type). Fix C++ virtual member fn comment.
2584 (read_struct_type): Avoid bumping pointer if we got a parse
2585 error; this prevents our walking beyond the end of a string.
2586 Terminate loop on null char as well as semicolon.
2587 (process_one_symbol): Fix the LBRAC fix so that it uses the
2588 last previous SLINE, FUN, or SO record's PC address. C++ debug
2589 symbols did not have SLINE records in a useful order compared
2590 to the LBRAC records.
2591 (define_symbol): Handle "catch" records.
2593 * symtab.c (check_stub_type): Added new complain
2594 `stub_noname_complain' and added a consistency check to
2595 keep the debugger from crashing when finishing from an
2596 exception frame. A real fix will be needed later.
2598 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2600 * infcmd.c (attach_command): Make global.
2602 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2603 but make them easy to comment out. Perhaps later they should
2604 be enabled by what CPU you configure for? FIXME.
2605 (VERSION): Roll to 3.93.
2606 (pinsn.o): Remove rule for obsolete file.
2607 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2609 Run down a problem that manifested by printing the wrong function
2610 name in stack traces of read_ofile_symtab. Turned out that the
2611 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2612 the LBRAC symbol with an address in the *data* segment, which
2613 blew our binary search through the blocks.
2615 * dbxread.c: Use the complain() facility consistently to bitch
2616 about problems in the symbol file we are reading.
2617 (finish_block): Add code to check the nesting of the blocks;
2618 complain and Procrust them to fit if wrong.
2619 (make_blockvector): Check the order of the blocks, complain
2620 [but don't cope] if wrong.
2621 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2622 symbols to be sure their PC value is greater than the last SLINE
2623 (line number) symbol we've seen, complaining and adopting the
2624 SLINE PC value if wrong.
2626 * symfile.h (struct complaint, complaint_root, complain,
2627 clear_complaints): Add.
2628 * symfile.c (complain, complaint_root, clear_complaints): Add
2629 facility to deal with non-fatal complaints and to regularize their
2631 (symbol_file_add): Clear complaint counters to allow new complaints.
2632 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2634 * dbxread.c (dbx_symfile_read): Remember the address and size
2635 of the string table for the main symbol file, so we won't read it
2637 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2638 to avoid reading the string table yet again. Lint.
2639 (throughout): Improve filtered output, including word wrap.
2640 (read_range_type): Improve Bothner's fix to handle other types too.
2642 * utils.c: Improve line wrap implementation. Handle unlimited
2643 width by making chars_per_line unsigned.
2644 (puts_filtered): New, easy, function.
2646 * defs.h (puts_filtered): add.
2648 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2649 call the identical sort_symtab_syms() in symfile.c instead.
2651 * expread.y: Suggest the `file' command rather than `symbol-file'.
2653 * command.h (enum var_types): Add zinteger for seroable
2655 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2656 nested if's into a switch.
2658 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2659 we did not stop because of a breakpoint (it must have been for
2660 some other reason, like a "stepi"), so don't print anything.
2662 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2663 doesn't include <sys/types.h>, old SunOS's require it for
2666 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2668 A test port of gdb-3.92.6 to the Sony NEWS.
2671 Don't normally link in remote- or vx stuff.
2672 Some of it doesn't compile, and it wastes space for 99% of the users.
2673 Remove reference to no-longer-used HAVE_VPRINTF.
2674 Fixed BFD_DEP typo to BFD_DIR.
2676 Fix cast in arg to bfd_h_getlong.
2677 Make char *prefix be const.
2678 Fix how certain range types are mapped into builtin unsigned int types.
2680 Remove 2 #includes. They cause errors (on Sony, at least),
2681 and aren't needed (they wern't in earlier versions).
2683 print_address_symbolic should never demangle labels
2684 (since it prints *assembler-level* labels).
2686 [This was superseded by the change to printcmd below.]
2689 Add some "volatile" return types to avoid warnings.
2690 If MISSING_VPRINTF add vprintf function and not just macro
2691 (since vprintf is used in printcmd.c).
2693 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2694 (The latter isn't grokked by some PCC-based compilers.)
2696 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2698 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2699 * nindy-share/coffstrip.c
2700 Added some forward declarations (otherwise, gcc complains
2701 about implicit extern redefined as static).
2703 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2705 Changes inspired by Per Bothner:
2706 * printcmd.c (print_address_symbolic): Take additional parameter
2707 specifying whether to demangle.
2708 (print_address): Pass in asm_demangle to control demangling.
2709 (print_address_demangle): New fn, takes explicit arg to control
2711 * utils.c: Add new vars demangle and asm_demangle, and let them
2713 (fputs_demangled): If !demangle, just print the argument.
2714 (fprint_symbol): If !demangle, just print raw symbol.
2715 * valprint.c (val_print): Call print_address_demangle rather than
2716 print_address, to cause demangling to depend on the global
2717 rather than assembler-level demangling setting.
2718 * WHATS.NEW, gdb.texinfo: Document.
2720 * main.c (show_command): Show all settings if no arg.
2721 (initialize_main): Make "info set" the same as naked "show".
2722 * command.c (cmd_show_list): Handle prefix commands in the
2723 list, and print the name of the setting as well as its English
2724 description and value.
2726 Allow gdb functions to specify where a line should wrap if it
2727 exceeds the size of a terminal line. Use it to make the output
2729 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2730 of the right size when screen width changes.
2731 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2732 (wrap_here): New fn, indicates a point in the output where we
2733 should wrap the line rather than just letting it overflow at a
2735 (fputs_filtered): Implement wrapping.
2736 (n_spaces): New fn, returns a pointer to N spaces.
2737 (print_spaces_filtered): Use n_spaces.
2738 * defs.h (n_spaces): Declare.
2739 * stack.c (print_frame_info): Wrap with 4-space indent after
2740 fn name and before filename and line number.
2741 * printcmd.c (print_frame_args): Wrap with 4-space indent
2742 before each argument name is printed.
2743 * valprint.c (value_print): Wrap with no indentation before
2745 (val_print_fields): Wrap with indentation relative to nesting
2746 level before each field name.
2747 (val_print): Wrap with nesting indentation before array elements.
2748 * command.c (do_setshow_command): Avoid extra newlines,
2749 wrap with 4-space indent around values printed, end with period.
2750 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2752 * breakpoint.c (breakpoint_1): Implement addressprint for
2753 "info breakpoints" display. Change file name and line number
2754 format to " at file:nnn" rather than " (file line nnn)".
2755 * gdb.texinfo: Document.
2758 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2760 Frozen for gdb-3.92.6 release.
2762 README, WHATS.NEW: Update for 3.92.6 release.
2764 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2765 coffread.o from configs since it is now built by default.
2766 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2767 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2768 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2769 from configs since it is now built by default.
2771 Makefile.dist: Update for release 3.92.6. Handle files that
2772 have been moved to ../include, ../getopt, or ../bfd. Add
2773 saber.suppress and tests directory. Add config.status to
2774 the release (it will say "none").
2776 coredep.c: Minor formatting fixes.
2778 These changes were made in early December but only checked in now:
2779 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2780 nindy-share/nindy.c: lint
2781 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2782 register values coming back from the target; we store values
2783 in target byte order everywhere.
2785 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2787 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2789 * valprint.c (cplus_val_print, val_print_fields): New functions,
2790 which print C++ objects. They conspire to avoid printing a
2791 virtual base class more than once, following all the twists and
2792 turns of C++ virtual base rules.
2793 (val_print): Call the above rather than do it by hand.
2795 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2796 symbol file, not for added files like shared libs. This really
2797 needs to be generalized to a timestamp per file.
2799 * core.c (cleanup_core): Avoid coredump if no core file.
2801 * config.gdb: Accept -host or -target in place of +host or
2804 * coffread.c (find_linenos): Avoid desupported BFD interface
2805 to line numbers. We still read them manually rather than using
2806 BFD's "generic" features.
2808 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2810 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2812 * Makefile.dist: Eliminate use of $< in explicit targets.
2814 * readline/Makefile: Use $< rather than $*.c, which does not
2815 include the VPATH in GNU Make.
2817 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2818 copies of tconfig/i960, added for global configuration
2819 compatability. All i960 versions can read both coff and b.out.
2821 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2822 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2825 * TODO: Think of more things to do.
2827 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2829 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2830 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2831 64-bit float conversion.
2833 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2834 equivalent to sun?os4 so global config works.
2836 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2838 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2840 * main.c: Only declare linesize once; declare pagesize not at
2841 all, since it is never used.
2842 (main): Clear newly allocated line before it is used.
2844 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2846 Further stabilization for the Intel 960.
2848 * Makefile.dist: Parameterize the location of the "include"
2849 and "bfd" directories, as well as "getopt". Add symfile.c.
2850 Link in both dbxread and coffread. Fix up "make depend" to
2851 rewack the locations of include, bfd, and getopt in its output.
2853 * README: Document moving include files, improve some of
2856 * coffread.c: Move common code out to symfile.c. Change
2857 symbol_file_command style interface to use new *_symfile_init
2858 and *_symfile_read interface under BFD. Use BFD internal
2859 info to locate line table, symbols, etc.
2861 * core.c (core_fetch_registers): Rename to get_core_registers
2862 to avoid confusion with fetch_core_registers.
2863 (register_addr): Move to coredep.c, which is already machine
2864 dependent. This leaves core.c pretty clean of dependencies.
2866 * coredep.c (register_addr): Accept this routine from core.c.
2868 * dbxread.c: Move common code (with coffread.c, etc) into new
2869 symfile.c. Each psymtab now contains a pointer to the
2870 format-dependent function that knows how to read it in. Make
2872 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2873 (process_one_symbol): Add code to complain about a "compiler bug
2874 we muzzle here", if we actually see it.
2876 * eval.c (evaluate_subexp): Insert missing "break" statements
2877 in code that determines whether a variable is an lvalue in
2878 memory, register, or whatever. I detected this via a compiler
2879 bug in which it *almost* mashed out the whole switch statement.
2881 * gdb-int.texinfo: Add minor sections on configuring gdb for
2882 release, and about the README file.
2884 * infcmd.c (registers_info): Fix formatting somewhat. Still
2885 not as pretty as before, but it handles byte swapping.
2887 * remote-nindy.c: If data cache routines are interrupted while
2888 waiting for the remote end, be sure that any uninitialized cache
2889 blocks are on the free list, not on the valid list!
2891 * symfile.h: Flesh out this header file with all the various
2892 routines and variables that have been merged in from dbxread.c
2893 coffread.c, and symtab.c to symfile.c.
2895 * symfile.c: New file, containing code common to dbxread.c,
2896 coffread.c, and some code from symtab.c. All generic code for
2897 reading symbol files should be in here now.
2898 (unrecord_misc_function): Remove unused function.
2900 * symtab.h: Remove file-reading things to symfile.h.
2902 * symtab.c: Remove file-reading things to symfile.c.
2904 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2905 to decode i960 fault types.
2907 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2908 target.c: Change type of the "resume" function from int to void,
2909 since its result was never used.
2911 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2913 * main.c: Replace "stupid" with "caution"; you now "set caution
2916 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2918 * infcmd.c (do_registers_info): Call val_print to deal with the
2919 byte order of the registers being printed. FIXME, this makes
2920 the formatting of the output uglier.
2922 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2923 defined, call it for signals the debugger doesn't itself use.
2924 The i960 uses this for more detailed fault information.
2926 * remote.c (remote_open): If arg is null, print help rather than
2929 * sparc-xdep.c (register_valid): Avoid declaring size, since
2930 various modules will think of various sizes depending on the
2931 architecture of their tm-file. FIXME, we need protection against
2932 actually entering one of those modules, which would clobber
2933 storage if not for the target architecture compiled into gdb.
2935 * stack.c (up_command, down_command): Always print the frame
2937 (up_silently_command, down_silently_command): New commands
2940 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2942 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2943 more parameters than it used to.
2945 * findvar.c (registers): Increase slop to 256 bytes, which should
2946 protect us against even most RISC machines with large register
2948 (locate_var_value): Move declaration inside related ifdef.
2950 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2951 throughout, to avoid throwing away buffered input from the board.
2952 (nindy_wait): Supply_register takes addr_of_value, not value.
2953 (i960_print_fault): Renamed from i80960_fault.
2954 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2955 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2957 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2958 we can set the PC in the call to proceed(). Unpush nindy_ops
2959 before pushing it on top, to avoid message to user. Eliminate
2960 commentary from Unix machines that just misleads here.
2961 (reset_command): Fix error message to suggest target command.
2963 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2965 Release 3.92.5 as frozen.
2967 Stabilize the merged release...with help from lint, Saber C,
2970 Everywhere: Add include files needed to declare return types
2971 of functions called.
2973 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2975 * breakpoint.h: Add undeclared breakpoint functions, and some
2976 functions for display handling since I couldn't think of a better
2979 * breakpoint.c (insert_breakpoints): Make code for disabling
2980 shared library bkpts more likely to work. It's used when we
2981 rerun a program and stop before the shared library has been
2983 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2984 cast from pointer, so it squeezes through catch_errors.
2985 (bpstat_stop_status): Fix logic broken some time ago. We now
2986 always create a bpstat if the stop address matches a breakpoint,
2987 even if we don't stop there -- just like the old code used to do
2988 before I got my fingers into it (sigh).
2989 (breakpoint_1): Print "ignore count" after "stop only if"
2990 condition, since that's how it actually works.
2991 (mention): Handle watchpoints as well as breakpoints.
2992 (watch_command): use set_raw_breakpoint and mention to do most
2993 of the work (and initialize all the fields!). Only pass one
2994 arg to parse_c_expression, since that's all it takes.
2996 * command.c (not_just_help_class_command): Rename arg to args
2997 since we ignore "unused argument" warnings on vars named "args".
2998 inflow.c (child_terminal_info): ditto.
2999 infptrace.c (kill_inferior): ditto
3000 main.c (catch_errors, version_info, quit_command, pwd_command,
3001 source_command, dump_me_command, editing_info,
3002 set_history_size_command, set_history, show_history,
3004 stack.c (locals_info): ditto
3005 target.c (target_files_info): ditto
3006 valprint.c (set_input_radix, set_output_radix): ditto
3008 * core.c: Remove old variables for handling core and exec file
3009 sections (data_start, data_end, stack_start, stack_end,
3010 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3011 text_end, exec_data_start, exec_data_end, text_offset,
3012 exec_data_offset, data_offset, stack_offset). They're
3013 superseded the more general build_section_table and
3015 (get_exec_file): Mention the `file' command.
3016 (read_memory_check): Rename to memory_error, and only call it
3017 in the case of an actual error.
3018 (read_memory, write_memory): call memory_error.
3019 (core_fetch_registers): Register section name is ".reg".
3021 coredep.c: Remove a bunch of crud now that all this file does
3022 is pull the registers out of a core file.
3023 (fetch_core_registers): Rewrite to actually work, I hope.
3025 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3026 Replace index() with strchr(). Remove all the pre-BFD macro
3027 definitions for accessing the symbol file.
3028 (struct dbx_symfile_info): Encapsulate the information that
3029 dbx_symfile_init needs to pass to dbx_symfile_read in this
3032 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3033 dbx_symfile_discard): Rearrange symbol file reading to divide
3034 the format-specific part from the format-independent part,
3035 leaving the format-independent part such as file name expansion
3036 and opening in symtab.c. This replaces
3037 partial_symbol_file_open and partial_symbol_file_read.
3038 Symbol_file_read, add_file, add_file_target_command,
3039 add_file_addr_command move to symtab.c. Pass an explicit
3040 "mainline" flag for when reading the main symbol table, rather
3041 than relying on the offset address to be zero or nonzero.
3043 (dbx_symfile_read): Don't allow void *'s to be printed as
3045 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3046 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3047 macro" debug version really work.
3048 (read_dbx_symtab): Remove unref'd parameter inclink.
3049 Avoid swapping N_SLINE symbols, for speed.
3050 Merge N_TEXT!N_EXT case with the other external symbol
3051 definitions' case. Add comments.
3052 (start_psymtab): Allocate the symfile name in the psymtab on
3053 the psymbol_obstack, rather than using the caller's storage.
3054 (end_psymtab): Only allocate a dependencies list if there are
3056 (psymtab_to_symtab_2): Use BFD when reopening file to read
3057 its symbols for real.
3058 (read_struct_type): Add FIXME comments where it needs work
3060 (read_huge_number): Add FIXME about overflows.
3061 (read_range_type): Add FIXME about comparing a long to 1<<32.
3063 * coffread.c: Minor changes to move things closer to the new
3064 regime with symtab.c and dbxread.c Major work is still needed
3067 * exec.c (exec_file_command): Remove old variables (see core.c
3069 (xfer_memory): If memory transfer is right at the end of a
3070 section, don't lose.
3072 * findvar.c (get_saved_register): If value is in a real
3073 register, LVAL is lval_register, not lval_memory.
3075 frame.h: Declare print_sel_frame and record_selected_frame.
3077 gdb-int.texinfo: New file, for GDB internals documentation.
3078 Very simple, unformatted doc of cleanups is there for now.
3080 gdbcore.h: Remove obsolete variables that described a.out
3081 section addresses and offsets. (See core.c above.)
3082 Declare fetch_core_registers and registers_fetched.
3084 getopt.c: Declare char *alloca(); even on SPARC.
3086 infcmd.c (run_command): Call target_kill rather than
3088 (step_command, next_command, stepi_command, nexti_command):
3089 Declare from_tty parameter even though we don't use it.
3090 (run_stack_dummy): argument BUFFER is a char array, not
3091 a pointer to REGISTER_TYPE.
3092 (finish_command): using_struct_return needed a value *,
3093 not a struct symbol *.
3095 * infptrace.c (child_xfer_memory): To avoid dependency on
3096 where sections are in memory, try PT_WRITE_D and if that fails,
3097 try PT_WRITE_I. Most Unixes don't care which you use.
3099 * infrun.c (step_resume_break_shadow): Change to array to
3100 match other breakpoint shadow storage.
3101 (clear_proceed_status): Pass address of bpstat to
3102 bpstat_clear, not the bpstat itself.
3103 (child_create_inferior): FIXME comment about if the child
3105 (start_inferior): Remove old function.
3106 (child_open): Use target_kill rather than kill_inferior.
3107 (wait_for_inferior): Ditto.
3108 (insert_step_breakpoint, remote_step_breakpoint): Use
3109 new step_resume_break_shadow.
3111 * inftarg.c (child_wait): If all child processes die,
3112 pretend that the one being waited for exited with signal 42.
3114 * main.c (command_line_input): When scanning for comments,
3115 don't coredump on unclosed quotes.
3116 (quit_command): Use target_kill rther than kill_inferior.
3117 (_initialize_main): Rename class_user from "user" to
3120 * printcmd.c (print_command_1): Initialize "fmt" if no format
3121 is specified by the user.
3122 (print_frame_args): Only add to args_printed if we are
3123 actually fetching args from the stack (avoiding undefined
3125 (_initialize_printcmd): Remove bogus \{ from string.
3127 * remote-eb.c (eb_open): Avoid coredump on no argument.
3129 * remote-nindy.c: Bring out of Intel environment into new
3130 target environment. Remove all conditional compilation on
3131 I80960. Massive hacking throughout.
3132 (nindy_xfer_inferior_memory): New routine stolen from
3134 (nindy_create_inferior): New routine pieced together, probably
3135 not quite working yet.
3136 (nindy_ops): New target_ops struct for nindy.
3138 * remote-vx.c: Use write_memory rather than target_write_memory
3139 to get error checking.
3140 (vx_add_file_command, vx_open): Use symbol_file_add rather than
3142 (vx_create_inferior): Use target_terminal_ours...
3144 * signame.c (_initialize_signame): Always initialize, since
3145 we need the table for things other than psignal.
3147 * solib.c (solib_add): Use symbol_file_add, not add_file.
3148 (solib_address): Return boolean result rather than struct
3149 pointer which nobody else knows the type of.
3151 * sparc-tdep.c, valops.c: Use write_memory rather than
3152 target_write_memory, to get error checking.
3154 * stack.c (locals_info, catch_info, args_info,
3155 get_selected_block, frame_command, up_command): Use
3156 target_has_stack, rather than have_inferior_p or
3159 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
3161 * symfile.h: New file, defining the interface between the
3162 generic and object-file-specific symbol reading code.
3164 * symtab.c: Move generic symbol-reading interface to symtab.c,
3165 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
3166 table to map BFD targets to symbol-reading modules in GDB.
3167 Change index to strchr.
3168 (lookup_struct_elt_type): Use error() rather than hand-made
3169 simulations thereof.
3170 (lookup_partial_symbol): Speedup slightly when length == 0.
3171 (symbol_file_add): New function.
3172 (symbol_file_command): Call it.
3173 (symfile_open, symfile_init): New function.
3174 (add_file_target_command, add_file_addr_command): moved from
3177 * target.c (target_command): use target_kill.
3179 * target.h (target_files_info): Don't declare, never called
3182 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
3183 files to determine stack end address.
3185 * valarith.c (value_x_binop, value_x_unop): Change error message
3186 to be more useful. Pass proper argument to value_struct_elt.
3188 * valops.c (value_assign): FIXME comment that long long
3189 bitfields will break here.
3191 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
3192 Update `make saber_gdb' to work better.
3194 * TODO: A woman's work is never done.
3196 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
3197 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
3198 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
3199 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
3200 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
3201 valops.c, valprint.c, exec.c: Lint.
3204 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
3206 Continuing Intel 960 port merge of GDB.
3208 * Makefile.dist: Merge i960 "nindy-share" files. Rename
3209 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
3210 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
3211 Wack over "make depend" so it handles files in subdirectories
3212 vx-share, nindy-share, bfd, and in the current directory.
3214 * blockframe.c (get_prev_frame_info): Remove fatal error
3215 if stack not defined.
3217 * core.c (core_open, core_detach): New functions that handle
3218 the old "core-file" command as "target core" and "detach" instead.
3219 (core_file_command): Call them.
3220 (core_xfer_memory): Use common routine xfer_memory.
3222 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
3223 dbxread now uses bfd for everything but symbol reading itself.
3224 BFD internals are used to drag out the relevant file offsets.
3225 (partial_symbol_file_open): Change args all around for BFD.
3227 * symtab.c: Rename "value" to "val" everywhere, so we can
3229 (symbol_file_command): New command, moved from dbxread.c
3230 and coffread.c. It uses BFD to read the file, then vectors
3231 based on its type, to dbx or coff symbol readers.
3232 * symtab.h: Extern a few vars for symbol_file_command.
3234 * target.h: Breakpoint takes a char * save area, not a char **.
3236 * valprint.c (val_print): When unpacking bitfields, offset
3237 the address in gdb of the value, if it is declared with a shorter
3238 type. Remove the last "runtime kludge test" of host byte order.
3240 * utils.c: Remove old my_bfd_read routine.
3242 * stack.c (frame_info): Use target_has_stack. Print program counter
3243 register's actual name rather than "pc", since it's called the
3244 "ip" (instruction pointer) on the i960 (sigh).
3246 * target.c (target_command): Add command for selecting a target
3247 type and calling its open routine. This is used for initiating
3248 communication with a particular target, in a generic way.
3250 * tm-i960.h: Update for modern gdb. Remove semicolons from
3251 various macros. Handle reading struct return convention, and
3252 error-out attempts to return structs with the "return" command.
3253 Be sure gdb doesn't think we know how to call functions in the
3256 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
3257 to i960_xxx in lower case.
3258 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
3259 not being defined yet.
3261 * remote.c (remote_open): Call start_remote to initialize
3262 wait_for_inferior during open.
3263 (remote_xfer_inferior_memory): Return length written rather
3266 * remote-vx.c (target_command -> vx_open): Use new generic
3268 * remote-eb.c, inftarg.c, exec.c: ditto.
3270 * infrun.c: Fix comments.
3271 (attach_program -> child_open): Use new generic target command.
3272 (wait_for_inferior): Clear saved register values before target_wait,
3273 so target_wait can set some of them if convenient.
3275 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
3276 Return success indicator, not void.
3277 (child_xfer_memory): Avoid fetching initial word if we'll
3278 overwrite it anyway.
3280 * infcmd.c (attach_command): Use new generic target open routine.
3281 (_initialize_infcmd): Update doc on attach and detach commands.
3282 (do_registers_info): Merge in a byte-order problem as a FIXME
3285 * findvar.c (find_saved_register): Avoid problem in current frame.
3286 (read_relative_register): Ditto.
3287 (write_register): Convert byte order on the way out.
3289 * exec.c (file_command): Add.
3290 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
3291 (xfer_memory): Common function between core_xfer_memory and
3293 (exec_xfer_memory): Use it.
3295 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
3297 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
3298 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
3299 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
3301 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
3303 Merge Intel 960 port of gdb, continuing...
3305 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
3306 symbol_file_command): Pass from_tty arg to hush 'em up.
3308 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
3309 Add magic numbers for 960 COFF format.
3311 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
3313 Merge Intel 960 port of gdb, from Intel "1.2" release.
3315 CHANGE_LOG entries from their port, which was based on
3318 Thu Sep 6 11:02:22 PDT 1990
3319 Remove temp file if download is interrupted.
3321 Wed Aug 1 09:08:33 PDT 1990
3322 Now uses binary protocol to talk to NINDY.
3323 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
3324 Times out after 5 seconds when trying to talk to NINDY.
3326 Tue May 29 12:54:49 PDT 1990
3327 Added variable baud rate (-b switch).
3328 Source code reorganization.
3330 Thu Apr 26 11:09:55 PDT 1990
3331 More cleanup of batch mode; specifically, execute "-s", "-e", and
3332 "-se" switches as soon as they are encountered on the invocation line.
3334 Fri Apr 20 13:47:15 PDT 1990
3337 Thu Apr 19 09:54:28 PDT 1990
3338 Add 'reset' command.
3340 Wed Apr 18 09:48:07 PDT 1990
3341 After opening remote tty, wait for 1 second to go by without input
3342 from it before trying to talk to NINDY (fixes problems with the
3343 Heurikon HK80/V960E).
3345 Mon Apr 4 16:33:05 PDT 1990
3346 Some output was not being suppressed in 'batch' mode.
3348 Thu Mar 22 15:31:11 PST 1990
3349 Ask user if old symbol table should be deleted when new file is
3352 Allow user to run a program downloaded before gdb960 was brought up.
3354 Correct "exec-file" help message for i80960 context.
3356 Correct bug in calculating user space address: could occasionally
3357 corrupt user program.
3359 Make sure to zero low-order bits in rip's because of bug in 960CA
3360 A-step part: could cause operation faults when "next"ing across
3363 Correct bug that made it impossible to get source line numbers for
3364 code loaded at addresses higher than 0x7fffffff.
3366 Wed Jan 10 12:43:22 PST 1990
3367 Open remote tty for exclusive use.
3369 Fri Jan 5 12:14:42 PST 1990
3370 Correct disassembly (CA manual was right after all):
3371 opcode for sysctl is 0x659
3373 Mon Oct 23 12:03:04 PDT 1989
3374 Use G960BASE and G960BIN environment variables to find 'sx' utility.
3376 Mon Oct 16 14:15:09 PDT 1989
3377 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
3379 Mon Oct 2 15:56:31 PDT 1989
3381 Added 960CA disassembly support.
3383 To simplify maintenance:
3384 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
3386 - eliminated opcode.h: incorporates tables into i960-pinsn.c
3387 - moved 960-specific routines from i960-pinsn.c to i960-md.c
3388 - made disassembly interface identical to that in gdmp960.
3392 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
3394 * target.h: Allow targets to stack. Add target_has_memory,
3395 _registers, etc. Restructure memory access and "info files"
3396 to walk the target stack.
3397 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
3398 target.c: Change tables to match target.h.
3399 * inflow.c (child_mourn_inferior): pop child_ops.
3400 (generic_mourn_inferior): Use new has_stack flag.
3401 * infptrace.c (child_xfer_memory): New memory regime.
3402 * inftarg.c (child_files_info): New "info files" regime.
3403 * remote-eb.c: New memory regime, new info files.
3404 * remote-vx.c: New memory regime, new info files. Now use
3405 separate targets for VxWorks attachment to machine, and
3406 actually running a process under VxWorks, since one has
3407 stack & execution & regs and the other doesn't.
3408 * remote.c: New memory regime, new info files.
3409 * sparc-xdep.c (fetch_core-registers): New memory regime.
3410 * target.c: New routines and support for stacked targets,
3411 new memory regime, new info files regime.
3414 Generalize section handling for an arbitrary number of sections,
3415 including use of the new BFD (binary file) library.
3416 * gdbcore.h: Add struct section_table.
3417 * exec.c (build_section_table): Iterate all sections and
3418 record what gdb needs to know about them.
3419 (exec_command): Use it.
3420 (exec_xfer_memory): Use the table.
3421 (exec_files_info): Print the table.
3422 * core.c (core_file_command, core_xfer_memory, core_files_info):
3424 * source.c (find_source_lines): Use bfd_get_mtime.
3425 * dbxread.c: Quick changes to make it compile with new BFD.
3426 * utils.c (error): Avoid using bfd_error in generic routines.
3428 * core.c (core_fetch_registers): Get from the ".regs" section of
3430 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
3432 * inferior.h (attach_flag): Export.
3433 * infcmd.c (run_command): use new target_create_inferior.
3434 * infrun.c (child_create_inferior): Don't return result.
3435 * Makefile.dist (VERSION): 3.91.4.
3437 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
3439 * breakpoint.c (bpstat_num): Handle breakpoints which have
3440 since been deleted, such as temporary breakpoints.
3441 infcmd.c (program_info): ditto.
3443 * core.c (core_file_command): Display the frame where the core
3448 * remote-vx.c (target_command): Merge in target command from
3449 targ-vx.c. A few other cleanups.
3451 * TODO, Projects: Lots more stuff to do...
3453 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
3455 Massive changes to wall off the remote-debugging interface
3456 behind a function vector. The port to handle VxWorks targets
3457 is also part of this.
3459 All files: Replace references to renamed functions,
3460 remove references to remote_debugging, remove references to
3461 have_include_file, have_core_file in favor of target_has_stack,
3462 target_has_memory, etc.
3464 * Modularize the breakpoint interface.
3465 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
3466 a breakpoint instruction.
3467 breakpoint.c: struct breakpoint's shadow_contents now sized as
3469 (insert_breakpoints): Vector to target to install breakpoints.
3470 (remove_breakpoints): Vector to target here too.
3471 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
3472 sparc-tdep.c (single_step): Use new breakpoint interface for
3473 the single-step breakpoints.
3474 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
3475 New file, contains routines to insert and remove breakpoints by
3476 reading out the old contents and later replacing them. This is
3477 how ptrace breakpoints work, and many remote systems as well.
3479 * tm-vxworks68.h: New config file, overrides a few things for
3480 Wind River's preferences.
3482 * target.h: New file, for transfer vector used to talk to the
3483 inferior (child, attached, core, exec, remote, etc). All accesses
3484 to the thing being debugged should come through these vectors.
3485 target.c: New file, routines to handle transfer vector.
3486 (various files): Add transfer vectors XXX_ops for the various
3487 targets and pseudo-targets (core files, etc) we support.
3489 * breakpoint.c (bpstat_stop_status): Further explorations of
3490 watchpoints and why things don't work all the time.
3491 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3493 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3494 the local gdbinit if it doesn't already have it.
3496 * core.c (core_ops): add and install.
3497 Allow core debugging without exec file.
3499 * dbxread.c (free_and_init_header_files): Merge two fns.
3500 (end_symtab): Free named symbol table when a new version comes in.
3501 (read_dbx_symtab): Relocate all kinds of symbols with base
3502 address. First step toward handling different text, data, bss
3504 (add_file_addr_command): Renamed add_file_command.
3505 (add_file_command): Vector to remote handler.
3506 Add "load" as an alias for "add-file" command.
3508 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3509 non-returning functions.
3511 * exec.c: Add exec_ops, and push it as a target when an exec
3514 * infcmd.c (run_command): Pass executable file name and arg list
3515 separately when starting an inferior. Permit "run" when no exec
3516 file is specified, for VxWorks.
3517 (detach_command): Move to child_detach in inftarg.c.
3519 * inftarg.c: New file. Unix-child-specific routines, and the
3520 child_ops structure.
3522 * inferior.h (registers): Export "registers" as the way for
3523 target dependent register handlers to find gdb's local copy of
3524 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3525 since it is now used by places that want wait_for_inferior to
3526 handle the grunge but want to see every trap from the inferior.
3528 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3529 Eliminate remote_debugging hooks in terminal handling.
3531 * infrun.c: Replace start_inferior with child_create_inferior.
3532 Move all the hair of Unix shells and ptrace idiosyncracies into
3533 child_create_inferior, so remote handlers don't have to deal.
3534 Remove running_in_shell. Rename stop_after_attach to
3535 stop_soon_quietly, and use it in a few other places where we want
3536 to just call wait_for_inferior and get control back on the first
3537 trap. trap_expected now never takes a value > 1.
3538 (init_wait_for_inferior): Initialize static vars when a new
3541 main.c (gdbinit): Add new hook for .gdbinit file name, let
3542 it be overridden by config files as GDBINIT_FILENAME.
3543 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3544 Both of these are used for VxWorks gdb.
3546 mcheck.c: rename include file "gmalloc.c" to avoid problems
3547 with system include file "malloc.c".
3549 param-no-tm.h: New include file, same as param.h but does not
3550 include the default "tm.h" file. This is used in files where
3551 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3553 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3555 remote-vx.c: New file, VxWorks remote debugging support. Uses
3556 RPC routines that are shared with the target system, in directory
3559 remote.c: Vectorize remote interface.
3561 source.c: Globalize source_path, and make an alias "l" for "list"
3562 since we now have the "load" command.
3564 sparc-xdep.c: Use new param-no-tm.h.
3566 symmisc.c (free_named_symtab): Add new function from Wind River.
3567 However, ifdef it out for now while we think about what it should
3570 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3572 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3573 non-Unix-children handle this with their own code in the target
3576 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3577 source and target lists. Add vx-share to default list of include
3578 directories. Add new files to src and target lists: mem-break,
3579 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3580 ${srcdir} versions of munch and createtags are used.
3582 * valops.c (find_function_addr): Split out of call_function.
3583 (call_function_by_hand): Rename call_function; this function
3584 calls functions in the target by laboriously patching the target
3585 word-by-word with the right stack, args, regs, etc.
3588 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3590 Handle AMD 29000 a bit better.
3592 * remote-eb.c (readchar): Mask received char log to make it readable.
3593 (remote_start): Pass arguments down to executing program.
3594 Make startaddr unsigned.
3595 infrun.c (start_inferior): Accept args, pass them to
3597 infcmd.c (run_command): Pass args down to start_inferior.
3599 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3600 the target object file format.
3601 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3603 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3604 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3606 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3608 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3609 * TODO: We did a few things, we have more to do though.
3611 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3612 * inflow.c (inferior_died): Clear deferred stores.
3614 * Debug problems with dummy frames and calls to the inferior.
3615 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
3616 * sparc-tdep.c (do_restore_insn): Simplify.
3617 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3618 (sparc_push_dummy_frame): Simplify and fix what we push.
3619 (sparc_pop_frame): Slightly more hair here, deciding whether
3620 we are restoring a saved PC or returning to a return address in %i7.
3621 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3623 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3624 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3625 * obstack.h (chunkfun): ditto.
3626 * defs.h (xmalloc, xrealloc): ditto
3628 * utils.c (quit): Grab the terminal from the child if necessary.
3630 * inflow.c (term_status_command): Rename to term_info, change
3633 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3634 (is_delayed_branch): Speed up.
3635 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3636 Still missing some float ops, and needs testing.
3638 * Support for input and output radixes other than base 10
3639 * defs.h (input_radix, output_radix): Declare.
3640 * expread.y (yyparse, parse_number): Handle changes of input
3641 radix, and ambiguous names-or-numbers in radixes >10.
3642 * printcmd.c (print_scalar_formatted): Print formatted hex
3643 numbers in varying column widths.
3644 * valprint.c (val_print): Use output_format to print scalar ints.
3645 (set_input_radix, set_output_radix, set_radix): Create.
3646 (set_output_radix): Set output_format from output_radix.
3647 (_initialize_valprint): add `set radix' but leave the others off.
3649 * main.c (execute_command): Let stupid questions be turned off.
3650 (_initialize_main): Handle "set stupidity", etc.
3652 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3653 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3655 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3657 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3658 bfd stuff is still screwed up, but with some manual work, it
3661 * breakpoint.c (bpstat_do_actions): Start over if a command
3662 proceeds the inferior, since the inferior will have stopped and
3663 will need to have its new stop-actions taken care of.
3665 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3666 compiler fits, simplify it.
3668 * gdb.texinfo (directory command): Doc new dir command.
3669 source.c (directory_command): "dir" now puts things on the front
3670 of the path, moves dups up front, and handles multiple names
3671 on the command line, inserting each one in order. It also
3672 blows away cached line and full_filename info.
3674 * stack.c (backtrace_command): Skip "more stack frames follow"
3677 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3678 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3679 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3680 The only odd one was Gould NP1, which had defined vprintf to
3683 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3684 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3685 variable, inspect_it.
3686 valprint.c (print_string, val_print): Use the global inspect_it
3687 to indicate whether to print in Epoch style or normal style.
3689 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3691 * printcmd.c (call_command): add an alias for the "print" command
3692 which runs expressions and doesn't print the result if void.
3693 (print_command_1): implement it.
3695 * command.c: Remove #if 0'd code. Initialize all the fields
3696 in add_cmd (). Rename do_nothing_command to
3697 not_just_help_class_command, and make it externally visible.
3698 command.h: add user_commands to struct.
3699 * main.c (define_command): Don't overload c->function with a char
3700 string as well as a function pointer.
3702 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3703 calling convention of value_struct_elt () that got dropped in
3706 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3707 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3709 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3711 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3712 until a good time (e.g. when we are about to run the child),
3713 saving ptrace calls.
3714 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3715 * tm-sparc.h: define DO_DEFERRED_STORES.
3717 * sparc-xdep.c (store_inferior_registers): when storing float
3718 registers, don't store stack regs too. When storing the SP,
3719 however, DO store the stack regs too. This fixes a bug in which
3720 the dummy frame is not recognized when a call_function finishes,
3721 because its frame pointer (in the stack regs) was never
3723 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3724 even though we don't know how to read them from an inferior.
3725 valops.c (call_function): Comment about storing SP.
3727 * infrun.c (save_inferior_status): Save away the original bpstat
3728 chain so it can be restored later. Install the copied version for
3729 use by whoever saved the status. It will be blow away by
3730 restore_inferior_status, and the original chain restored. This is
3731 important for people who have pointers into the original.
3733 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3734 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3735 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3738 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3740 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3741 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3742 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3744 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3746 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3747 Store the baseclasses in a type struct starting from array element
3748 0 rather than from the unusual array element 1.
3750 dbxread.c: the above.
3751 (virtual_context): Add
3752 Read new debug information about which virtual function table
3753 a virtual function is from, and store it in fn_field.fcontext.
3755 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3756 TYPE_FN_FIELD_STATIC_P.
3758 symtab.c: the above.
3759 valops.c: the above. Handle pointer casts of object *'s.
3760 (search_struct_method): Add.
3761 (value_struct_elt): First arg is now a pointer to a value, and is
3764 valprint.c: the above.
3765 values.c (value_virtual_fn_field): Add type arg. Handle
3766 offsetting to the proper object when calling virtual fns.
3768 (baseclass_addr): Add valuep arg.
3770 * README: Document the current state of BFD config (missing).
3771 * TODO, ChangeLog, Makefile.dist: Roll version.
3772 * WHATS.NEW: Add summary of changes since 3.5.
3774 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3776 * dbxread.c (read_struct_type): Clear bit vectors whenever
3778 symtab.c (B_CLRALL): define.
3780 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3781 using == rather than =. Huh... This fixes the dreaded problem
3782 wherein builtin_type_int becomes TYPE_CODE_FLT.
3784 * core.c (info_files): Show the inferior pid.
3786 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3787 already knows how to look in the source directory.
3789 * Remove psymtab hair from many places. Remove duplicated code
3790 for searching symbol tables. Hide psymtabs from most places.
3791 Make it fast to get from a psymtab to its symtab.
3793 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3794 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3795 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3796 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3797 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3798 new symtab completely. New psymtabs get symtab pointer
3799 initialized to zero. Remove MI warning printf.
3800 symtab.h: Comments. Add psymtab to symtab pointer.
3801 (PSYMTAB_TO_SYMTAB): New macro.
3802 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3803 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3805 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3807 (print_frame_info): Avoid special-casing symbols that have not yet
3810 * source.c (open_source_file): Quick path if we have already
3811 located the source file by its full name.
3813 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3814 find_pc_psymtab. When a name is found in the misc function
3815 vector, search the symbol table for its mangled name, not the
3816 name that the user typed.
3818 * bfd.h: Fix missing comment terminators, make #endifs match.
3820 * valarith.c (value_less): Handle unsigned int comparisons.
3821 Add FIXME about pointer compares, which assume host and target
3822 pointers are the same.
3824 * command.c (do_nothing_command): lint
3825 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3826 fix comments on debug symbol format for visibility. Actually set
3827 visibility of symbols.
3828 main.c (echo_command): lint; use <readline/history.h>.
3829 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3830 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3831 pointing past end of allocated memory; saber complains.
3832 obstack.h: Declare the external functions that we use.
3833 valarith.h: use <string.h>
3834 solib.c (solib_add): lint.
3836 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3838 * main.c (initialize_main): Default info_verbose to off, now that
3839 symbol reading is fast.
3840 (quit_command): Avoid clobbering exec_bfd while quitting.
3842 * Initial BFD (binary file diddling library) merger:
3843 coffread.c: Change AOUTHDR to struct exe_hdr.
3845 core.c: initialize initialized data at compile time.
3846 (core_file_command): Move from coredep.c, convert to bfd.
3847 (xfer_core_file): Convert to bfd.
3848 exec.c (exec_file_command): use bfd routines.
3850 mips-tdep.c: Remove exec_file_command and friends.
3853 * coredep.c: (fetch_core_registers) Convert core_file_command to
3854 fetch_core_registers.
3855 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3857 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3858 (my_bfd_read): More bogosity, which I don't think we call.
3859 (program_name): Remove this atrocity asap!
3861 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3864 values.c: allocate_repeat_value was not clearing the
3865 optimized_out field.
3866 (value_static_field): minor stylistic fix (wrong macro was used).
3867 valops.c (value_struct_elt_for_address): didn't work for C++
3870 * signame.c (_initialize_signame): Initialize signal names once.
3872 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3873 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3874 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3876 * remote-eb.c: Support user-settable baud rates on the serial port.
3878 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3880 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3882 * tconfig/sun3os4: Remove warning about native assembler,
3883 since it also occurs in the xconfig file.
3885 * findvar.c (registers): Allocate some slop after `registers'
3886 to prevent stray accesses from trashing the next variable.
3888 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3889 on the sun-3, by changing the #ifdef from `sun3' (which is not
3890 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3891 vars, which happened to follow `registers' in the executable.
3893 * readline/history.c (history_search): Heed gcc-2's advice
3894 and parenthesize && inside ||).
3896 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3897 tm-29k.c: Insert FSF copyright headers.
3899 * remote-eb.c: Better comments.
3901 * Makefile.dist: Update to 3.91.6.
3902 * TODO: note PREPARE_TO_STORE problem.
3904 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3906 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3908 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3910 * infrun.c (wait_for_inferior, at end): Don't set up
3911 prev_* if the inferior no longer exists.
3913 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3914 CANNOT_EXECUTE_STACK.
3915 valops.c (call_function): Use it.
3917 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3919 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3920 infrun.c (wait_for_inferior, 2 places): Use it.
3922 * values.c (value_being_returned): Only use
3923 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3925 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3926 right thing for remote-eb.c.
3928 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3929 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3931 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3932 (FRAME_FIND_SAVED_REGS).
3934 * findvar.c ({fetch,store}_registers): Check for
3935 REMOTE_{FETCH_STORE}_REGISTER macro.
3937 * findvar.c (get_saved_register): Add argument lval and
3938 change meaning of argument addr.
3939 findvar.c: Change calls to get_saved_register to reflect
3940 new calling convention.
3941 valops.c (value_assign): Use get_saved_register instead of
3942 find_saved_register.
3944 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3946 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3947 an (uninitialized) pointer to one. Use "&" when passing it
3950 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3952 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3955 * coffread.c (symbol_file_command): Put semicolon after
3957 Put safe_to_init_tdesc_context in #if defined (TDESC).
3958 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3959 coffread.c: #include <sys/stat.h>.
3960 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3961 Add missing ')' in check for "lc%" and friends. Remove
3963 Declare read_one_sym() at top of file.
3964 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3965 MC68WRMAGIC can have the same value without causing a duplicate
3968 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3970 * Allow a Makefile to be built without building the
3971 tm and xm file links that screw up builds in subdirectories.
3972 This is done with `config.gdb none', then you can do things
3973 like `make gdb.tar.Z'.
3974 * tconfig/none: Config file for no target system
3975 * xconfig/none: Config file for no host system
3976 * config.gdb: If no TM or XM files are called out by the
3977 host or target file, don't make links for them.
3979 * cplus-dem.c: Add documentation.
3981 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3982 simple error, so the user's gdb doesn't crash due to some object
3983 file problem (e.g. somebody is rebuilding the file out from under
3986 * printcmd.c (print_address_symbolic): demangle the symbol.
3988 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3989 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3990 (alldeps.mak): sort and uniq all results from this; duplicates
3991 hose gdb.tar.Z link building. Remove RCS files from
3992 tconfig and xconfig. Add config files for sun386. Add
3993 a few odd files to OTHERS and HFILES.
3995 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3997 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3998 Roll version number to 3.91.5. Make lint work in bindir.
4000 * README: Document cross-debugging and new file structure.
4002 * blockframe.c: Lint. Include "value.h" to declare read_register.
4003 (find_pc_partial_function): remove duplicate line.
4005 * command.h: Lint. Declare error_no_arg and dont_repeat.
4007 * tm-news.h: Remove inadvertently duplicated stuff.
4009 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4010 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4012 * config.gdb: Allow `config.gdb host target' form. Clean
4013 up previous change that printed bogus messages when you just said
4016 * core.c: #include "command.h" for lint.
4019 * main.c: Remove some casts of enums. Lint.
4026 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4028 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4029 read it from memory. This will allow us to save ptrace calls
4030 eventually. Changed caller single_step too.
4032 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4033 that we aren't going to use, saving many ptrace calls, especially
4034 when watchpointing or single stepping. Use some #define's for
4036 (store_inferior_registers): Ditto.
4037 (core_file_command): Use some #define's for constants.
4039 * tm-sparc.h: Add #define's for some register numbers, so we
4040 can eliminate the use of random constants in sparc-xdep.c.
4042 * stack.c (frame_command, print_frame_info, up_command,
4043 down_command) Remove frame_changed, since it
4044 causes a bug and doesn't seem to do anything useful. In some
4045 places it was used as a flag, in others as a stack level (?).
4047 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4048 default is to use the portable (vprintf) version rather than the
4050 * xm-news.h (MISSING_VPRINTF): Add.
4052 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
4054 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
4056 * Remove stuff that forces -Bstatic linking of gdb, and warnings
4057 about linking debugged programs -Bstatic in the sun?os4 config
4058 files in tconfig and xconfig subdirectories.
4060 * main.c (main): Remove unreached exit(0) now that we exit
4063 * Create TODO file for online bug list. There are too many
4064 "little" bugs to keep track of on paper.
4066 * Change Projects file to refer to bug-gdb@cygnus.com
4067 rather than kingdon@ai.
4069 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
4071 * Makefile.dist (VERSION): 3.91.4 now.
4073 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
4074 (condense_misc_bunches): Add sanity check that misc_count is
4075 the same as the number of symbols in the bunch.
4077 * coffread.c: rename init_misc_bunches. Pass an argument
4078 to condense_misc_bunches (a zero).
4080 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
4081 every time we are called; don't rely on our caller to do it.
4082 (add_file): Remove call to init_misc_bunches.
4084 * mipsread.c: Only warn, don't error, if unknown symbol types.
4085 This keeps an old gdb from falling on its face if it sees newly
4086 extended symbol info. Rename init_misc_bunches.
4088 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
4090 * Merge in changes from Per Bothner for DECstations and other
4091 MIPS stuff. The rest is Bothner speaking:
4093 The next message is a merger of Alessando Forin's mips port with
4094 mine. I've tried to use my good if biased judgment to get
4095 the best of both. It *does* need testing.
4097 Some of the changes are general, *not* mips-specific.
4100 Didn't believe in little-endian bit order.
4101 There are still inconsistencies about whether flags
4102 like BITS_BIG_ENDIAN are integer (#if ...) or
4103 boolean (#ifdef ...). I tried to paper over them.
4105 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
4106 Moved some misc_function code that was common to
4107 {dbx,coff,mips}read.c to symtab.c.
4108 In the process, I think I cleaned things up a bit.
4109 At the same time, moved obsavestring and obconcat to symtab.c.
4112 Removed obsolete condense_addl_misc_bunches (use
4113 condense_misc_bunches(1) instead).
4116 Needed to include <sys/dir>, at least on DECstations.
4118 valops.c, mips-tdep.c, tm-mips.h:
4119 Added PUSH_ARGUMENTS macro to support funny argument-pushing
4120 conventions (when STACK_ALIGN is insufficient).
4121 Needed on mips, where doubles need 8-byte alignment,
4122 but ints only need 4.
4125 Removed cruft that was not being used.
4126 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
4129 Print $ before register-names (I think that makes things a little
4131 Never print two instructions, even if one delays.
4132 Removed hex-disassemble set_cmd. (This is not mips-specific,
4133 so I think the argument is whether it is generally worthwhile or not.
4134 I'm inclined to think not, given how easy it is to
4135 convert between radixes in gdb.)
4138 This is basically Alessando's code.
4139 It doesn't use obstacks; I changed it to use obstacks
4140 in a few minor places where using malloc causes a
4141 memory leak. (Probably, more places could/should be changed.)
4142 I added record_misc_function where it was missing.
4143 In symbol_file_command and add_file_command, I tried
4144 to make the code consistent with more recent versions.
4145 Minor sylistic changes in parse_procedure.
4146 Make a .gdbinfo. psuedo-symbol point back to the real
4147 procedure symbol (using the isym field).
4150 This is basically from my port, but with a lot of details
4151 and a number of routines merged in from Alessando's version.
4152 I basically used my code "raw" backtrace (use heuristics
4153 from the actual code, rather than symbol table info) - though
4154 the idea is Alessandro's. I feel my code is a little cleaner
4155 here, particularly in being a little more flexible, such as being
4156 able to handle gcc-produced code (which it now can).
4157 It also doesn't do frame caching (which is not useful
4158 more recent gdb versions).
4159 I also used my code for push_/pop_dummy, more or less.
4160 I tried to incorporate AF's code for testing sigtramp
4161 while backtracing; I probably got it wrong.
4162 Added mips_print_register, which tries to scrunch as much
4163 information as possible on a screen...
4164 Removed the skip-prologue set_cmd. As with hex-disassemble (see
4165 under mips-pinsn.c), I don't see anything mips-specific here,
4166 and I don't see it being all that useful anyway.
4169 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
4170 Use more register names (rather than hard-cases numbers).
4172 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
4174 * Hack up 3.90.11 changes:
4176 * Makefile.dist (depend): parameterize $(GCC).
4177 Add solib.c and solib.o.
4178 (readline): Fix vpath for both absolute or relative SRCDIR.
4180 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
4181 Also, let the part I didn't understand at least compile so
4182 I can test the rest. FIXME.
4184 * dbxread.c: Fix thinko using strcmp.
4185 (init_psymbol_list): declare static.
4186 (partial_symbol_file_open): Comment cleanups better, avoid
4187 cleaning up the string table since the caller will do that.
4188 Move the stat for mod time into symbol_file_command, temporarily.
4189 (There should be a mod time for each symbol file, eventually,
4190 to control its rereading. FIXME.)
4192 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
4193 SunOS, which gives error for shared libs otherwise. (From
4194 Schaefer, probably FIXME needs work for portability.)
4196 * solib.c: Move #include "param.h" to work.
4197 Lowercase all the Uppercase Letters In the Messages.
4198 (find_solib): Clean up inferior_so_name for debug printouts.
4199 Allow no argument, to mean all shared libraries.
4201 * symmisc.c: include param.h to get CLEAR_SOLIB.
4203 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
4205 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
4206 to 3.90.11. ChangeLog entries below are from this.
4208 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4212 * Makefile.dist (HFILES): Add tm-sunos.h.
4214 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4218 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
4220 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
4222 * sparc-opcode.h Added single-operand version of rett.
4224 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4226 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
4227 Put parens around gcc_p in expansion.
4229 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4231 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
4233 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4235 * Changes for Sun shared libraries:
4236 blockframe.c (find_pc_partial_function): If a non-text symbol
4237 is found, set *address = pc - FUNCTION_START_OFFSET.
4238 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
4239 Disable breakpoints instead of giving an error.
4240 source.c (select_source_symtab): Initialize cs_pst.
4241 symmisc.c: Call CLEAR_SOLIB if defined.
4242 symtab.h: Make text{low,high} CORE_ADDR not int.
4243 (psymtab): New field addr.
4245 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
4246 (record_misc_function): Give correct type for N_DATA symbols.
4247 (condense_misc_bunches): do "misc_function_count = j" regardless
4249 Take code which is shared between symbol_file_command and
4250 add_file_command and put it into partial_symbol_file_{open,read}.
4251 Split add_file_command into add_file_command and add_file.
4252 Make psymtab_to_symtab read in the string table if the file
4254 Two new parameters to read_dbx_symtab and start_psymtab.
4255 tm-sunos.h: New file.
4257 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4259 * infcmd.c: Change cont_command to continue_command and "cont"
4262 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4264 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
4266 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
4268 * values.c (USE_STRUCT_CONVENTION): Check for structures of
4269 size 1,2,4,8 rather than size < 8.
4271 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
4272 as necessary, not just once.
4274 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
4276 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4278 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
4280 * tm-news.h: Add CALL_DUMMY_*.
4282 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
4284 * config.gdb: In list_host, list_target, use ${i}, not $i.
4286 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4288 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
4290 * sparc-opcode.h: Change all store floating-point state register
4291 instructions to have the right match & lose fields.
4293 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4295 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
4297 config.gdb: If srcdir != ., create readline directory and
4298 copy a makefile into it.
4300 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
4301 consistency with POSIX.
4303 * breakpoint.c (bpstat_stop_status): Disable watchpoint
4304 when we exit its exp_valid_block.
4306 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
4308 * Makefile.dist: Bump version to 3.91.3.
4310 * Clean up handling of breakpoint commands (somewhat).
4311 Prompted by Tiemann bug report "cont 10" doesn't work any more.
4313 inferior.h: Add breakpoint_proceeded to inferior status struct
4314 and globals; save it and restore it.
4315 (clear_breakpoint_commands): Cleanup, remove old #define.
4317 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
4318 (save_inferior_status, restore_inferior_status): handle it also.
4319 (proceed): Remove earlier code that set breakpoint_proceeded.
4320 It is now set only in clear_proceed_status.
4321 (clear_proceed_status): Cleanup, use bpstat_clear rather
4322 than clear_breakpoint_commands. No callers need the stop_bpstat
4323 between clear_proceed_status and proceed.
4325 infcmd.c: Add breakpoint_proceeded definition and comment.
4326 (cont_command, jump_command, signal_command): Move call to
4327 clear_proceed_status right next to call to proceed.
4329 breakpoint.c (bpstat_do_actions): Avoid clobbering our
4330 caller's argument while running down the chain of breakpoints.
4331 Use new variable "breakpoint_proceeded" to determine when
4332 a command that it executes moves the inferior past the
4334 (bpstat_clear): Handle NULL argument.
4335 (bpstat_clear_actions): Avoid useless call to
4336 breakpoint_auto_delete.
4337 (delete_breakpoint): Clean up bpstat's that are pointing to
4338 the deleted breakpoint from the stop_bpstat chain.
4339 (breakpoint_auto_delete): Simplify.
4341 * Clean up handling of EOF, error on stdin, etc. This was
4342 prompted by a network problem that caused gdb to go into an
4343 infinite loop filling up its malloc'd memory.
4345 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
4346 not clear_breakpoints_commands, which is now gone.
4347 (main): If command_loop returns (e.g. from EOF on stdin), do
4348 a quit_command (looping back to command_loop if quit_command
4349 doesn't really quit).
4350 (command_loop): check result from command_line_input and
4351 exit if it returns NULL, rather than passing the NULL to
4353 (gdb_readline): Free malloc'd result space before returning
4356 * utils.c (query): Handle C-d to mean "yes", just as if the
4357 input was not a terminal. Also avoid infinite loop if EOF
4358 occurs in mid-input-line before newline. This allows
4359 query to be used at EOF on stdin with reasonable results.
4361 * infrun.c (proceed): Set breakpoint_proceeded.
4363 * values.c (value_as_long): Avoid infinite recursion for enums.
4364 (_initialize_values): Fix typo in help msg (kingdon).
4366 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
4367 RL_LIB for linking. This allows -lreadline for linking
4368 and nothing for dependencies, once readline is a real library.
4370 * config.gdb: Jim Kingdon: give useful error message if the
4371 host or target type is not recognized.
4373 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
4374 it just defines it. Dumb, but deal with it.
4376 * Jim Kingdon suggests:
4377 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
4379 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
4381 * Makefile.dist (VERSION): Bump version # to 3.91.2.
4383 * Clean up Bothner's changes.
4385 * blockframe.c (clear_pc_function_cache): New function.
4386 * blockframe.c: remake cache_pc_function_* static.
4387 * dbxread.c (symbol_file_command): remove references to
4388 cache_pc_function_* variables.
4389 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
4390 * printcmd.c: Avoid kludging a global variable (addressprint)
4391 to avoid printing the address of a string twice. Instead,
4392 pass the format letter 's' down low enough that it can be seen
4393 to avoid this problem.
4394 (print_formatted): Pass format arg to value_print.
4395 (restore_addressprint): Remove function.
4396 (do_examine): Avoid hacking addressprint, cleanups and such.
4397 (print_frame_args): Add a comment to a Bothner change.
4398 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
4399 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
4400 to wipe out the values cached in blockframe.c.
4401 * symtab.c (find_method): Add comment saying how big you must
4402 allocate to be "big enough". Per being terse again.
4403 * valprint.c (val_print): Handle format letter "s" to print
4404 strings without addresses. Add comment to vtbl printing code
4405 which casts with wild abandon. Rearrange reference-printing
4407 @0xaddr: value (print w/addressprint)
4408 value (print w/~addressprint)
4409 @0xaddr (parameter lists w/addressprint)
4410 or nothing (parameter lists w/o addressprint)
4412 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
4414 * Merge more changes from Per Bothner:
4416 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
4417 annoying) that I tried to improve it. Here are my suggestions.
4419 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
4422 Do automatic de-reference when taking the address of a reference.
4424 Don't deref_ref when printing parameter lists.
4426 More attempts at treating refernences properly.
4428 In val_print, if deref_ref==0, don't print dangling " = ".
4430 Add COERCE_REF macro, which de-references an REF.
4432 * Merge changes from Per Bothner:
4434 * Fixed (Sony news)-specific configuration problems.
4435 * Fixed other problems with using vanilla pcc and libc (enum problems;
4436 assumption that vsprintf exists).
4437 * Some major speed-ups (finc_pc_partial_function now caches a match;
4438 parsing avoids duplicate symbol_lookup calls).
4439 * Changed handling of baseclasses (no longer use baseclasses field
4440 of struct type, use the first n_baseclasses fields instead).
4441 * Various minor changes/fixes, most C++-related.
4444 Cache the most previous match from find_pc_partial_function.
4445 (Save both low and high ends of matching function's pc range.)
4446 This speeds up the loop of infrun.c:wait_for_inferior quite
4447 a bit, and makes step/next commands much zippier.
4449 Added an enum->int cast (otherwise, some compilers barf).
4451 No longer set baseclass offset to 0, since multiple
4452 inheritance now mostly works.
4453 Added a number of casts, to shut up compiler warnings
4454 (after stabs where made enums, not ints).
4455 When discarding a symbol table (in symbol_file_command),
4456 must clear the cache introduced in blockframe.c.
4457 Don't convert $vtbl_ptr_type to vtbl any more.
4458 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
4459 Mask off sign bit emitted by g++ for virtual table offset.
4460 Set voffset to -1 (not 1) for static member functions.
4462 Changed parsing/lexing of names to avoid doing symbol lookup twice
4463 (once when lexing to determine symbol class, once for real).
4464 Now only call symbol_lookup once. Fields of 'this' win especially big.
4466 Subpress printing addr twice in the case of 'x/s addr'.
4468 lookup_basetype_type is no longer used.
4469 Add find_methods as recursive helper function to decode_line_1.
4470 This allows multiple inheritance to work.
4471 Also, once one or more matches has been found, do not look in
4472 base-classes. (Baseclass methods would be overridden, anyway.)
4474 Removed baseclasses array in struct type.
4475 Instead of using baseclasses[i], use fields[i-1].
4476 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
4477 Changed sign convention of voffset (previous was inconsistent).
4479 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4481 Used to assume existence of vsprintf. Re-written to not need it
4482 if HAVE_VPRINTF is undefined.
4484 typecmp was too pessimistic. Made it less so.
4486 Don't print space after address.
4487 If vtable points to a misc symbol (with 0 offset), print it,
4488 since that indicates the actual class of the object.
4489 Changed ype_print_derivation_info to use new inheritance
4490 scheme (without baseclasses vector).
4492 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4493 Also, changes needed because TYPE_BASECLASSES were removed.
4495 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4497 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4500 If there is no path set, and the symbols don't indicate what directory
4501 a file was compiled in, look in the current directory. But either
4502 a path or a known compilation directory will prevent this.
4505 Three independent bug fixes:
4506 * Remove the #if 0 block that breaks some stuff.
4507 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4508 adapt gdb to either SunOS 4.0.* or 4.1.
4509 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4512 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4515 (type_print) Demangle the name being printed.
4516 (type_print_base) Handle botched demangling without coredump (tiemann).
4519 (check_stub_method): Document routine.
4520 (tiemann) fix bug for no-arg functions
4521 Avoid clobbering beyond end of malloc'd storage.
4522 Terminate the argument list properly.
4524 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4526 * Changes merged by John Gilmore:
4529 In breakpoint_1, use new print_address_symbolic instead
4530 of find_pc_partial_function. (This forces use of assembler-level
4531 addresses, and avoids misleading non-mangled source-level names.)
4533 Generalize ansi argument such that -1 means skip arglist totally.
4534 Removed global variable print_ansi_qualifiers (which made
4535 code non-reentrant), in favor of extra explicit arguments
4536 to internal routines.
4538 Add new helper function print_address_symbolic.
4539 Use find_pc_misc_function instead of find_pc_partial_function
4540 (since we want assembler-level symbols here).
4542 Print unknown function as just "f (...)", not "f (...) (...)".
4543 Use new fputs_demangled explicitly.
4545 Fixed a typing violation (problem: value.h cannot be imported
4546 without renaming many variable in this file).
4547 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4548 decode_line_1: Moved forward some never-reached code.
4549 Made decode_line_2 skip function prologues correctly.
4551 fputs_filtered should not demangle by default.
4552 Add new fputs_demangled to demangle on demand..
4554 Change value_struct_elt to use value_primitive_field (using recursive
4555 utility function search_struct_field). This allows foo.bar to work
4556 for multiple inheritance (so far only for data fields).
4557 Change check_field in the same way (recursive helper function
4558 to support multiple inheritance).
4559 (Note: there are more of these problems that I haven't fixed.
4560 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4561 value_of_this: 'this' symbol name is now just "this", note "$this".
4563 Don't print static members.
4564 Avoid printing "members of <type>" if there are none.
4565 Simplified type_print_derivation_info by merging duplicate code.
4566 Remove useless blank lines in type_print_base (ptype command).
4568 Added declaration of new routine value_primitive_field.
4570 Added value_primitive_field which is generalized version of
4571 value_field that can handle multiple inheritance (non-zero offsets etc).
4572 Re-implemented value_field to call value_primitive_field.
4574 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
4576 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4577 delete the whole environment. Karl Berry reported the bug.
4578 * source.c - fix openp to avoid //'s in filenames, which
4579 trigger an Emacs bug causing it to not be able to find files
4580 when running gdb in a window.
4581 * dbxread.c - zap the #if 0 that botches the add-file code.
4582 It seems to work a lot better without all the code commented out.
4584 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
4586 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
4589 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
4591 * Makefile - added a ${CFLAGS} to a couple of entries,
4592 added remote-sa.sparc.c
4593 * added remote.sa-sparc.c, a modification of remote.c
4594 which conducts a dialog directly with the SparcStation prom.
4595 * breakpoint.c, infrun.c, sparcdep.c added
4596 remote_insert_breakpoint(), and remote_remove_breakpoint()
4597 to breakpoint.c instead of directly writing breakpoint instructions.
4598 * sparcdep.c on remote_debugging,there is no need
4599 to remove signle step breakpoint instructions.
4600 * main.c added "-epoch" flag and "int epoch_interface" to main.c
4602 * printcmd.c - epoch interface sends lisp expressions to open up
4603 epoch windows on inspection.
4604 * valprint.c - added arrayprint, and addressprint and made adding
4605 format controls easier
4606 * wait.h added a couple of undef's because we were getting
4607 complaints about WSTOPSIG and WTERMSIG begin redefined.

4677 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
4678 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
4679 when printing the type.
4681 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)

4703 step_resume_break_address != NULL, even if another_trap.
4704 If trap_expected and we enter sigtramp, then set up a
4706 If trap_expected is set when we hit the step_resume_break,
