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

733 symtab.h, target.c, target.h: Lint.
734 * core.c: setup and select frame after reading shared libs,
735 else reading shared libs will clobber them. Lint.
736 * utils.c (error): Force out any buffered wrap text.
738 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
740 * remote.c: Remove decls of memory_insert_breakpoint
741 and memory_remove_breakpoint, no longer used. (Suggestion of
744 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
745 to make it easier to interface to "configure"'d libraries.
747 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
749 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
750 aliases for set/show print.

1301 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
1302 to the main file, as well as to include files. Also, put global
1303 functions into the global psymtab, to make "i fun" work.
1304 (end_psymtab): Free named symtabs and psymtabs for a file, once a
1305 new psymtab for it has been read.
1306 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
1307 a file, once a new symtab has been read for it.
1308 * mipsread.c: FIXME. We need to do the same for MIPS, but it

1310 queued to the psymtab list.
1312 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
1313 If we have wiped out any old symbol tables, clean up at end of

1329 static psymbols list.
1330 (types_info): Restore this function from its untimely #if 0.

1354 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1355 (set_section_command): New command ("section xxx yyy" -- should
1356 be renamed to "set section xxx yyy" FIXME) which sets the
1357 base address of a section of the exec file, overriding the
1358 virtual address that BFD reports.
1360 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1362 * exec.c: Add add_syms_addr_command to exec_ops, so you can

1367 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1368 for printing the float info is host-dependent, not
1369 target-dependent. FIXME.
1370 * i386-pinsn.c: Move #includes to top, remove useless ones.
1371 * i386-tdep.c: Don't bother including <.../reg.h> since we
1372 don't use it (and it doesn't exist on host systems).

1375 Convert negative numbers properly.
1376 (ieee_test): Make numbers really random; fix format arg.
1378 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1379 * core.c (core_detach): Unpush core_ops, which might not be on

1381 need dont_repeat() any more.
1382 (core_file_command): Psst! Don't repeat it.
1383 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1384 * expprint.c (print_subexp): Avoid switch fallthru on
1385 BINOP_ASSIGN_MODIFY, so we can print += and such.
1386 * frame.h: Fix typo.
1387 * inflow.c (kill_command): After killing inferior, print our
1388 current frame in the core file, if we have one.
1389 (generic_mourn_inferior): When inferior dies, either select
1390 the current frame (in the new target, e.g. core file), or
1391 set both the current and selected frames to NULL.
1393 Changes from Peter Schauer.
1395 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1397 * Make all file names fit in 14 characters (sigh and damn!):

1399 mv symmetry-xdep.c symm-xdep.c
1400 mv symmetry-tdep.c symm-tdep.c
1401 mv convex-opcode.h convx-opcode.h
1402 mv tm-vxworks960.h tm-vx960.h
1403 mv tm-vxworks68.h tm-vx68.h
1404 mv Makefile.srcdir Makefile.sdir
1405 mv gdb-int.texinfo gdbint.texinfo
1406 mv remote-sa.m68k.shar rem-m68k.shar
1407 mv remote-multi.shar rem-multi.shar
1408 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1409 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1410 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1413 * command.c (user_info_1, user_info): New command for listing
1414 the user-defined commands.

1418 * dbxread.c (really_free_pendings): Clear file_symbols
1419 and global_symbols after freeing them; otherwise, running
1420 this function twice (if it appears twice on the cleanup
1421 chain), we try to free things twice.
1423 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1424 based on text_addr (the address of text in core), not on addr (the
1425 offset between text in the .o file and in core). This change
1426 is from Peter Schauer.
1428 * main.c: Define ALL_CLEANUPS as a cast of zero.
1429 (return_to_top_level): Use it.
1430 (main): Do all cleanups after each command run as part
1431 of the gdb startup sequence. Also do all cleanups before
1432 entering the command loop, and every time we exit the command
1433 loop and reenter. Before, the cleanups from the startup sequence
1434 were being left undone until the first error!
1435 (command_loop): Rename do_nothing cleanup to command_loop_marker
1436 so we can see it easily when examining the cleanup chain.
1437 (init_signals): Add another do_nothing for signal handling.
1438 (quit_command): Only try to kill target if it has execution.
1439 Problems in the target stack got us into a state where
1440 inferior_pid was nonzero but none of the targets had execution.
1441 In this state you couldn't exit gdb.
1443 * dbxread.c: Two changes from Peter Schauer.
1444 (echo_command): Fflush output after an echo command.
1445 (show_history): Pass all args to cmd_show_list.
1447 * utils.c (init_malloc): Call mtrace to turn on tracing
1448 if the environment variable MALLOC_TRACE is set to a file name.
1449 * mtrace.c: Add source file which provides a log of every malloc,
1450 free, and realloc to a trace file.
1451 * mtrace.awk: Add source file which analyzes the trace file.
1452 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1453 (VERSION): Roll to 3.94.3.
1455 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1456 (check_duplicates): Don't bother with watchpoints.
1457 (set_raw_breakpoint): Comment about danger of this routine.
1458 (watch_command): Parse and eval all args before calling
1461 * solib.c (find_solib): Avoid error in referencing memory to
1462 see if any more shared libraries have been added. This is
1463 particularly useful if the target has terminated. Bug reported
1466 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1467 in bringing up 3.94.2 on the Sun-3.
1469 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1470 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1471 expression (in scope) before reenabling watchpoint.
1472 * signame.c (init_sigs): Add missing declaration of i, fix
1473 sys_siglist declaration.
1474 * source.c (list_command): Fixed range computation to use
1476 * stack.c (backtrace_command): Do not allow command if target has
1477 no stack, print informative error message.
1478 * target.c (target_command): Do not write into command line
1479 because this fails if the target command is used in a user defined
1480 command. [This change was enhanced by gnu to support any-
1481 unique-prefix matching on target names.]
1482 * valops.c (value_struct_elt): Avoid infinite loop on an
1483 erroneous attempt to print the member of function (try p main.p).
1485 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1487 * expread.y (name_no_typename): Avoid reduce/reduce errors
1488 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1489 Since the GDB parser really doesn't use name_no_typename in a
1490 name-only context, the parser can't tell the diff between
1491 names and numbers here. Avoid allowing a name_no_typename
1492 to be a NAME_OR_*INT to resolve the conflict.
1494 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1496 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1498 * valprint.c (val_print_fields): bitfield printing didn't handle
1499 byte order. Indirect through a few more fns to cope.
1501 * values.c (modify_field): also cope with byte order.
1503 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1505 Cleanup for release 3.94.2:
1507 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1508 include files. Roll version to 3.94.2.
1510 * coffread.c (init_stringtab): Read length into unsigned char
1511 array before swapping; don't assume 32-bit longs.
1513 * target.c (target_info): Don't bother with get_sym_file, just use
1514 the symfile global variable.
1515 * symtab.h, symfile.c (get_sym_file): Delete it.
1517 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1518 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1519 (read_type): Replace one more error() with complain().
1521 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1523 * i960-tdep.c: Fix copyright attribution.
1525 * config.gdb: Quote all backquotes in doublequotes. You can
1526 quote me on that. BSD 4.4 shell found this one.
1528 * infptrace.c (throughout): The third argument to ptrace is an
1531 * infrun.c (wait_for_inferior): When program has terminated, we
1532 have to call target_terminal_ours before we pop that target off
1533 the stack (e.g. before a call to target_kill or
1534 target_mourn_inferior). This fixes problem where a program
1535 terminates, then GDB stops for (tty output) and you have to type
1536 "fg" to the shell to resume it. FIXME: This code for what to
1537 do after termination really should be in normal_stop instead.
1539 * gdbcore.h (read_memory_check): Change declaration; it changed
1542 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1543 4.4 prereleases, this avoids a bug in their sgtty compatability
1545 * remote.c: Use terminal.h rather than hand-rolling the same.
1547 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1548 * utils.c (strsave, strstr): Fix arg types.
1549 * valprint.c (val_print): lint
1551 MIPS symbol table support from Per Bothner:
1553 * symfile.c (symtab_fns): Remove initializer table that needs to
1554 be hacked for each new symbol file format supported.
1555 (add_symtab_fns): New function, chains symbol table
1556 handlers into the global list.
1557 (symfile_init): Search this list.
1558 * symfile.h: Add next pointer, declare add_symtab_fns.
1559 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1560 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1562 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1563 symbol *). Thus, we no longer need the hack to trash
1564 pst->filename. Good, since that hack confused code in symfile.c!
1566 (reorder_symtabs, destroy_all_symtabs): Removed static
1567 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1568 Instead, the latter now uses a temporary array (stack-allocated
1569 from an obstack, and then freed).
1571 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1572 haven't been set in the outermost stBlock of a procedure. This was
1573 a problem with f77 binaries on Ultrix 4.?.
1575 (new_symtab, new_symbol, new_type): Continue changing code to use
1576 obstacks more and otherwise conform to dbxread internal style.
1577 Made the free_code of symtabs be free_linetable (as in dbxread)
1578 instead of free_contents. This implies memory leaks when reading
1579 a new symbol table, until the conversion is finished. Did change
1580 (struct symbol) and (struct type) to be allocated on the
1581 symbol_obstack. Blocks and blockvectors are among the things
1584 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1585 tested much, but it solved one problem (reported by Meissner), and
1586 cleans up some other things. The problem happened when an
1587 included file contains actual code (functions) and not just
1588 definitions. The mips coff is a little inconvenient there, since
1589 it may cause a procedure to be mapped to the wrong psymtab.
1591 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1592 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1593 this will need work for the new core paradigm.
1595 Opcode patches from the net:
1597 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1598 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1599 missing altogether - they are added here. From Bruce Bauman.
1600 * mips-opcode.h: The low mask for C0 instructions was too small.
1601 From Garrett Lau. I modified the fix to check the entire 32-bit
1604 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1607 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1609 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1611 * dbxread.c (read_type): Pointer subtraction (value_sub in
1612 valarith.c) sometimes failed because the types of the
1613 pointers being subtracted were not identical.
1614 These differed because dbxread.c was allocating pointer types
1615 using dbx_alloc_type+smash_to_pointer_type instead of
1616 lookup_pointer_type. I failed to find a justification for the
1617 former, so I changed it to use the latter. Similarly, I
1618 replaced smash_to_function_type by lookup_function_type,
1619 and smash_to_reference_type by lookup_reference_type.
1621 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1622 _initialize_mipsread): corresponding changes.
1624 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1626 * source.c (mod_path): Do tilde_expand on each component of the path,
1627 rather than on the (list of) paths as a whole.
1628 (print_source_lines): Set first_line_listed in addition to
1629 current_source_symtab and current_source_line. If the source was
1630 not findable, after a "dir" command to fix the problem,
1631 a "list" would get the wrong lines.
1633 While I was there... (gnu):
1635 * dbxread.c (read_type): Change error to complaint.
1637 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1639 First attempt at detailed understanding of symbol table memory alloc.
1641 * dbxread.c (dbx_symfile_read): Free our string table if we
1642 aren't the mainline. Free the "info" struct since we're done with
1644 (init_psymbol_list): Free any previously allocated psymbol lists.
1645 (): FIXME: Should realloc-down the psymbol lists when done reading
1646 the main symbol file?
1648 * symmisc.c (free_symtab): Free fullname field too.
1650 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1651 (REGISTER_ADDR): Make result type unsigned int.
1653 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1654 define REGEX must also define REGEX1 (its dependency).
1656 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1658 * tconfig/i960: No longer works, points you at vxworks960 or
1661 * xgdb.c, XGDB-README: Remove file. Users can get the much
1663 * Makefile.dist: Remove all trace of xgdb.
1665 * breakpoint.c (breakpoint_1): Pass demangle arg to
1666 print_address_symbolic.
1667 (clear_breakpoints): Remove unused function.
1668 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1669 (breakpoint_re_set): Use catch_errors to do them all anyway.
1671 * gdb-int.texinfo (Host versus Target): Add section on what is
1672 a "host" feature versus what is a "target" feature.
1674 * infcmd.c (path_command, path_info): Handle the PATH variable
1675 (object search path) as conveniently as the source search path.
1676 * environ.c (set_in_environ): Set some vars in GDB's environment,
1677 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1678 * source.c (mod_path): New function, from guts of
1679 directory_command, modifies a path. Used by path_command.
1680 (directory_command): Call it.
1681 * defs.h (strsave): Declare.
1683 * utils.c (sevenbit_strings): Add new printing option.
1684 (printchar): Use it.
1685 (strsave): Provide this handy helper routine.
1686 (set_width_command): Rename set_screen_width_command.
1687 (_initialize_utils): "set screen-width" => "set width";
1688 "set screen-height" => "set height"; add sevenbit-strings.
1690 * infcmd.c (do_registers_info): Print floating point registers
1691 in raw hex as well as float format, regardless of whether it is
1692 a "virtual" convertible register.
1693 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1694 regs as a double, just in case it's being used that way.
1695 * values.c (unpack_long): Comment on array/function coercion.
1696 (unpack_double): Argument is in target byte order now. For
1697 integer arguments, just call unpack_long and float the result.
1698 * m68k-tdep.c: include defs.h for "const" handling.
1699 * remote-nindy.c: Use ieee-float stuff.
1700 (nindy_fetch_registers): Unpack double regs to host double, then
1702 (nindy_store_registers): Pack extendeds to host double, flip
1703 around by misusing unpack_double, send as target double.
1705 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1706 zero, as when stopped at the first instruction of a process.
1708 * blockframe.c: Fix filename in comment (param.h => tm.h).
1709 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1710 * tm-68k.h: Fix typos.
1712 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1714 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1716 * coredep.c (fetch_core_registers): Pass end-address of register
1717 section to register_addr as expected. Don't call supply_register
1718 if we'd just pass it garbage.
1720 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1722 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1724 * target.c (push_target, target_info): Cast enums to int for < or
1727 * stack.c (print_frame_info): Identify source file & line
1728 even if we can't print it.
1730 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1732 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1734 Clean up IEEE floating point support.
1736 * ieee-float.h: New file.
1737 * ieee-float.c: Write real routines to convert between host
1738 doubles and various target IEEE extendeds.
1739 * m68k-xdep.c: Eliminate assembler code for extended floats.
1740 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1741 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1742 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1743 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1744 double_to_ieee_extended.
1745 * i960-tdep.c: Define ext_format_i960.
1746 * m68k-tdep.c: Define ext_format_68881.
1747 * sparc-tdep.c: Define ext_format_sparc, though unused.
1748 * Makefile.dist (HFILES): Add ieee-float.h.
1749 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1752 Obsolete the "coffstrip" program in favor of using BFD's strip.
1754 * nindy-share/coffstrip.c: Remove file.
1755 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1756 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1757 * tconfig/nindy960: Remove reference to coffstrip.o.
1759 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1761 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1763 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1764 * dbxread.c: Remove static symfile_bfd.
1765 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1767 * inftarg.c (child_detach): Pop the child_ops vector if the
1768 detach is successful.
1769 * remote-nindy.c (nindy_create_inferior): Don't push a new
1770 nindy_ops since nindy uses the same one for execution and memory
1772 * core.c (core_ops): Use child_attach and child_create_inferior
1773 rather than default attach and create_inferior functions.
1775 Handle floating point registers in core files.
1777 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1778 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1779 This version untested since BFD doesn't yet support sun3 core
1781 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1782 conventions. Fix comments and style. This version has not
1783 been compiled yet, since we have no HP inhouse.
1784 * core.c (get_core_registers): Look for two sections, ".reg"
1785 and ".reg2", and pass both to fetch_core_registers sequentially.
1787 Revise directory path yet again.
1789 * source.c (forget_cached_source_info): Not static any more.
1790 (init_source_path): New default source path is "$cdir:$cwd".
1791 (dir_command): Handle variable arguments ($cdir, $cwd).
1792 (source_info): Print "Compilation directory" rather than
1793 "Originally compiled in" to remind people of $cdir.
1794 (openp): If the path contains $cwd, use current directory.
1795 (open_source_file): If compilation directory is known, replace
1796 first $cdir in path with the compilation directory.
1797 (print_source_lines): Even if we can't print the lines, set the
1798 current symtab and line for future commands like "info source" or
1799 "breakpoint". Also, error message now contains the file name,
1800 line number, and file access error message.
1801 (_initialize_source): Fix help text to describe changes.
1802 * main.c (cd_command): Forget cached source info when we chdir.
1803 * utils.c (strstr): Add simple implementation.
1805 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1807 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1808 Byte-swap COFF symbol tables if necessary when reading them in.
1809 Use complain() to replace error message in one spot. Needs
1810 corresponding change in bfd/coff-code.h to make some symbol
1811 swapping routines non-static.
1813 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1815 Merge changes from Eirik Fuller, for UTek.
1817 * defs.h (errno): Add declaration.
1818 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
1819 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1820 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1821 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
1822 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
1823 declarations of errno.
1825 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1827 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1828 <rpc/rpc.h> and <rpc/types.h>.
1830 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1832 * i960-tdep.c (examine_prologue): Add new argument limit,
1833 which stops the scan at the end of the prologue, or at the PC.
1834 This fixes a problem where it walks down into the code for the
1835 user's statements if that code looks like function prologues.
1836 Mark Fox and I have been bouncing this code back and forth, making
1837 small changes to it. Callers changed to match.
1839 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1841 Cleanup for gdb-3.94 release final:
1843 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1844 the .c files from vx-share and nindy-share, from the various
1845 macros, since they are not found via ALLDEPFILES.
1846 (SFILES): Add tm-i960.h.
1847 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1848 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1850 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1851 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
1853 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
1855 * am29k-tdep.c: Add contribution line.
1856 (examine_prologue): Cache information about function prologues in
1857 the misc-function-vector to avoid lots of references over the
1858 serial line while examining instructions.
1860 * core.c (core_close): New function made from cleanup_core.
1862 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1863 remote-vx.c, remote.c, target.c, target.h,
1864 Update target_ops vector to add attach, close, and load entries.
1865 Use add_syms_addr_command, not add_file_addr_command, for
1866 add_file. Break out close routine from existing code.
1868 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1869 they are in an obstack.
1870 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1872 (define_symbol): Add symbol type parameter; change callers;
1873 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1874 it to influence the symbol class on the i960.
1875 (define_symbol): Swap LOC_CONST's into target byte order.
1877 * exec.c (exec_close): New function.
1878 (exec_file_command): Call it.
1880 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1881 Fix byte order of frame pointer.
1882 (read_var_value): Result of 0 if var's value can't be found,
1883 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1884 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1885 (locate_var_value): Use read_var_value and use its lazy address
1886 as the location of the var's value. Lint.
1888 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1891 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1892 obsolete Intel versions in favor of vxgdb versions.
1893 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1894 code dealing with byte order of values, which Intel did in host byte
1895 order rather than gdb-4's target byte order.
1896 (i960_frame_chain_valid): Move to nindy-tdep.c.
1897 (examine_prologue, skip_prologue, frame_find_saved_regs,
1898 frame_args_address, leafproc_return, saved_pc_after_call,
1899 pop_frame): Add vxgdb versions from Mark Fox.
1900 (examine_prologue, frame_struct_result_address): Add code
1901 to deal with the saved value of G13 (struct return address
1903 (frame_args_address): Modify Mark's version to prefer the
1904 saved value over the current value in the topmost frame.
1905 Cache result in the frame info to avoid performance hair in
1907 (print_fault): Add gdb960 code for printing faults.
1908 (_initialize_i960): Actually call check_host.
1910 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1911 add stub routines. FIXME, these currently just return zero!
1913 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1914 (attach_command): Call target_attach, not target_open, now.
1916 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1917 (child_attach): Rename from child_open.
1918 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1919 don't confuse it with a zero step_resume_break_address.
1921 * inftarg.c (child_detach): Eliminate inferior_pid test.
1922 (child_files_info): Clean up message a bit.
1923 (child_ops): Use child_attach, not child_open, to attach.
1925 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1926 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1927 findvar.c to here, since it depends on the contents of the
1928 shadow_contents of breakpoints, but keep if #if 0 since it is
1931 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1934 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1935 (ptype_command, display_command): Eliminate have_inferior_p and
1936 have_core_file_p in favor of target_has_stack or
1937 target_has_execution.
1938 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1939 code for actually finding the values of arguments, though we still
1940 keep track of the maximum stack offset for use in printing unnamed
1941 arguments. Handle missing FRAME_ARGS_ADDRESS.
1943 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1944 (struct nindy_regs): Define registers passed to/from nindy.
1945 (nindy_fetch_registers, nindy_store-registers): Translate between
1946 nindy and GDB formats for the registers.
1947 (dcache_init): Statically allocate the cache, since it was being
1948 allocated by a malloc that was never freed anyway.
1949 (nindy_create_inferior): Error, not core dump, if no exec file.
1950 (nindy_before_main_loop): Use target_load, not target_add_file.
1952 * remote-vx.c (net_load): Specify large timeout for load
1953 requests. Allow user to break out with INTERRUPT.
1954 (net_break): Remove useless code, clean up. Change callers.
1955 (parse-args, skip_white_space, find_white_space): Clean up arg
1956 parsing to cope with quoted strings.
1957 (net_wait, net_quit): Never call error, just return status.
1958 (vx_read_register, vx_write_register): Cleanup status checking.
1959 #ifdef the code based on which CPU we are using (960 or 68k),
1960 FIXME, this should be completely general but it isn't yet.
1961 (vx_xfer_memory, vx_resume): Cleanup status checking.
1962 (vx_run_files_info): Improve message.
1963 (vx_load_command): Renamed from vx_add_file_command. Allow load
1965 (net_ptrace): Remove unused routine.
1966 (vx_wait): Adopt code from vxgdb960 to cope with broken
1967 connections to target machine and prompt to disconnect. Remove
1968 debug printouts. Map some EVENT_'s to SIGnals.
1969 (add_symbol_stub, vx_open): Print names of object files we found,
1970 and "ok" if we read their symbols OK. Clarify output in general.
1971 (vx_attach, vx_detach, vx_kill): Add these commands.
1972 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1973 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1974 "info files" output, and create_inferior, since we already have
1977 * stack.c (frame_info): Replace Frame_unknown with 0.
1978 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1979 (return_command): Pop until the PC matches as well as the FP,
1980 so it works even if the FP is shared with another function,
1981 as in "frameless" or "leaf" procedures.
1983 * symfile.c (load_command): renamed from add_file_target_command.
1984 (add_syms_addr_command): renamed from add_file_addr_command.
1985 (add_syms_command): Stub to call target_add_syms.
1986 (_initialize_symfile): Change command names and descriptions,
1987 add-file => add-syms, and load from alias to its own command.
1989 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1990 maybe_kill_then_create_inferior): Default for attempts to start
1991 a process, if one is already running, is to ask about killing
1992 it and retry if yes.
1993 (upstack_create_inferior): #if-0 it, strata obsolete it.
1994 (push_target, unpush_target, pop_target): to_close() a target
1995 before unstacking it.
1996 (target_info): Renamed from target_files_info.
1997 (_initialize_targets): Rename "i files" as "i target", accessible
2000 * target.h: Improve comments about the target_ vectored routines.
2002 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
2003 Convert commenting style to standard GNU style.
2004 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
2005 (SKIP_PROLOGUE): No longer a no-op.
2006 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
2007 (*_REGNUM): Sort register numbers.
2008 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
2009 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
2010 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
2011 are now 10 byte extendeds, not 8 byte doubles.
2012 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
2013 for nindy versus vxworks targets. FIXME, this should possibly go
2014 in the target vector.
2015 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
2016 frame_saved_regs and arg pointer with each frame.
2017 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
2018 (FRAME_ARGS_ADDRESS): Use cached result.
2019 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
2020 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
2021 (PRINT_RAMDON_SIGNAL): Call print_fault.
2022 (POP_FRAME): Now works.
2024 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
2025 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
2026 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
2027 (ADDITIONAL_OPTION_HANDLER): use target_load, not
2030 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
2031 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
2033 * valarith.c (value_subscripted_rvalue): Avoid handling
2034 floats and doubles specially; it gave alignment errors. Lint.
2036 * valops.c (value_of_variable, value_of_this): Error if unknown
2039 * valprint.c (print_floating): Bcopy rather than pointer-deref,
2040 to avoid alignment problems.
2041 (value_print): Handle unknown value address.
2042 (cplus_val_print): Two args are ignored; remove them. Change caller.
2043 (val_print): Use unpack_long rather than pointer-deref.
2046 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
2047 to avoid alignment problems.
2048 (value_being_returned): Error if return value unknown.
2049 (set_return_value): Add bogosity warning, FIXME. *
2051 * TODO: A woman's work is never done.
2053 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
2054 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
2055 Add ieee-float.o to OBS.
2056 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
2057 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
2058 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
2060 Changes to generalize the VxWorks RPC protocol slightly, to handle
2061 i960 as well as 68000.
2063 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
2064 * vx-share/reg.h: Produce i960 regs #ifdef I80960
2065 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
2066 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
2067 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
2068 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
2069 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
2070 so they will move in target byte order rather than network
2071 byte order (happens to be the same).
2073 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2075 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
2077 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2080 Add contribution lines to various files, showing where they
2083 * breakpoint.c (break_insn, check_break_insn_size,
2084 read_memory_nobpt): Remove to mem-break.c.
2086 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
2089 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
2090 entry has bad register number. This change is not
2091 tested in this release, FIXME.
2093 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
2096 * value.h: Force value's contents field to be aligned to hold
2097 at least a double or a long long (if supported). This avoids
2098 doing bcopy's in and out of the contents field.
2100 (step_1): Avoid coredump under obscure circumstances when we
2103 * symtab.h (misc_info): Add field to misc function vector for
2104 any kind of cached information the target code desires. AMD
2105 29000 uses this to avoid repeating examine_function_prologue's.
2107 * coffread.c: Lint. Remove static symfile, read_section_header.
2108 core.c (have_core_file_p): Lint: remove.
2109 expprint.c (print_subexp): Lint.
2110 infptrace.c, valops.c, valprint.c: lint.
2112 Roll in changes from vxgdb-5.0.1:
2114 * symtab.h: Comment byte order of each address class. Add
2115 LOC_LOCAL_ARG for frame-relative args (960).
2116 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
2117 symtab.c, symmisc.c: ditto.
2119 * infrun.c (init_wait_for_inferior): Clear stop_signal.
2121 * remote.c (remote_resume): Error if resume with a signal.
2123 * symfile.c (prim_record_misc_function): Clear misc_info.
2124 (fill_in_vptr_fieldno): Check stub type of arg.
2126 * valops.c (value_cast): Avoid looking up names of types whose
2127 name we don't know, to prevent coredump. Sun CC produces typedef
2128 rtx and the name of *rtx is zero...
2130 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2132 Roll in changes from final AMD 29000 port (Tiemann).
2134 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
2135 for ../include/a.out.encap.h. This might not work now that BFD
2136 is separately compiled. Instead, BFD support for encap will have
2137 to translate machine type 29k into the right COFF_MAGIC.
2139 * infcmd.c: Remove references to inferior_pid that aren't used
2140 in actual ptrace calls; use target_has_execution, etc.
2141 (have_inferior_p): Remove function.
2142 (program_info): Print target info rather than "process number";
2143 avoid gratuitous messages unless from_tty.
2144 (run_stack_dummy, finish_command): Set proceed_to_finish.
2145 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
2146 main.c: Lint. Lose have_inferior_p().
2147 inferior.h (have_inferior_p): Remove, lint.
2148 (proceed_to_finish): Add flag to ask that all regs be saved
2149 by normal_stop, for the few commands that need it, speeding up
2150 serial I/O. Add comments to stop_registers.
2152 * remote-eb.c: Remove newline from breakpoint message we grep
2153 for. Never time out when running the user program.
2157 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2159 Roll in changes from vxgdb-5.0.1:
2161 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
2162 symbol in its raw form, we are processing an unlinked ".o" file.
2163 See if the target environment has assigned it an address, using
2164 target_lookup_symbol (VxWorks does), and enter it into the symtab
2167 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
2168 68k versions for a simpler version that assumes zero FP at bottom.
2169 Fixes bug of truncated stack reports.
2171 * target.h (target_lookup_symbol): Define this routine's args
2172 and result, finally.
2174 * target.c (nosymbol): Default routine for target_lookup_symbol.
2175 (target_default): Default lookup_symbol and call_function too.
2176 (files_info): Only print has_all_memory warning if a non-dummy
2179 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
2180 vx_convert_from_virtual): If target does not have floating point,
2181 zero register "values", and avoid doing cross-net conversions.
2182 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
2183 (vx_open): Rearrange code that attaches to target and reads
2184 symbols for all loaded modules, to work if some of the modules
2185 are not accessible. Add symbol_stub() and add_symbol_stub()
2186 as callbacks from catch_errors(). Allow connect attempt to be
2187 interrupted painlessly with ^C (FIXME, there are still some bugs
2188 if the interrupt happens during symbol reading.). Print
2189 final message with puts_filtered, since symbol messages are
2194 * main.c (catch_errors): Only print errstring if non-null.
2195 (command_loop): Avoid an ioctl per command to test ISATTY.
2197 * remote-vx.c (net_load): make static; avoid sophomoric msg.
2198 (vx_xfer_memory): Return correct result!
2199 (vx_files_info): Indicate whether target has float or not.
2200 (vx_lookup_symbol): Complain, not error, if target gone.
2201 (vx_open): Print "Connected" msg before disabling immediate-quit.
2202 [FIXME: lookup_symbol and vx_open changes need testing.]
2204 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
2205 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
2206 contributor lines and update copyrights to 1991.
2208 Changes from an attempted H-PUX host port:
2210 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
2211 defines PT_ATTACH and PT_DETACH but not PT_KILL.
2212 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
2213 * remote-vx.c: include <sys/time.h> for HPUX.
2214 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
2215 "core_file_command" routine to BFD regime. May not work yet.
2217 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
2219 * xgdb.c: Replace X10 version with some VJ version.
2220 (FIXME: Its copyright assignment is not on record.)
2221 * xgdb.c: Update include files to X11R4 (Xaw crud).
2222 (xgdb_display_source, create_text_widget): fix call to
2223 get_filename_and_charpos. Rewack source window stuff for X11R4
2224 (gleaned from include files, and "nm's" of binary libraries, since
2225 I had no doc available).
2226 (append_selection, append_selection_word): Disable with FIXME
2227 since R4 changed interface here.
2228 (create_buttons): Add back the old set of buttons.
2229 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
2231 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
2232 Roll VERSION to 3.94 (not yet final though).
2234 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2236 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
2237 obstack_int_grow, obstack_int_grow_fast): Eliminate
2238 cast on left of assignment, which gives MIPS cc fits and is
2241 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
2242 F_ALIAS. Use printf, not fprintf, when not passing a file
2244 (compare_opcodes): Check that identical instructions have
2245 identical opcodes, complain otherwise.
2247 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
2248 was reported by Roland McGrath.
2249 (unimp): Only match if exactly zero instruction. (Roland)
2250 (branches and traps): Generate all variations of these
2251 instructions with macros, based on a single call that defines
2252 each condition name and its binary representation.
2253 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
2255 * valprint.c (val_print_fields): Take, and use, format parameter.
2256 This means that "p/x struct" again prints the elements in the
2257 desired format. Changed callers.
2259 * stack.c (frame_info): Use filtered output, and indicate wrap
2260 points. Remove kludgy formatting designed to avoid line wrap.
2262 * utils.c (wrap_here): If the line is already full (because
2263 we had printed a long indent or long wrapped string), do an
2264 immediate newline-and-indent.
2266 * m68k-pinsn.c (print_insn_arg): Bugfix from
2267 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
2268 instruction is incorrectly disassembled as bkpt #8.
2270 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
2271 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
2272 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
2273 and then will dump core (sometimes). I traced it back to an
2274 uninitialized symfile_name in psymtab_to_symtab.
2275 (const_vol_complaint): Add quotes to message.
2276 (define_symbol): Only believe line number if gcc_compiled.
2277 Avoid allocating symbol if we will not return it.
2279 Add target strata support so that newly established targets go
2280 into their right place in the target stack (e.g. a new exec file
2281 doesn't wipe out the ability to access the running process).
2283 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2284 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2285 and initialize it properly in all the targets.
2287 * target.h: Document strata. Change return type of push_target.
2289 * target.c (nomemory): new function for dummy memory access.
2290 (tcomplain): Rename complain, now also used in symfile.c.
2291 (push_target): Push targets within strata. New return value shows
2292 whether new target is on top of stack or not. Always keep dummy
2294 (target_files_info): Ignore dummy target.
2296 * core.c (core_open): Warn user, and skip accessing file, if the
2297 core target is not the topmost target in the stack.
2298 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2301 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2302 target_ops, it doesn't belong there since we have no regs there.
2303 Change name of target from machine => memory to clarify.
2305 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2307 * Freeze version 3.93 for release.
2309 * Makefile.dist: Handle vx-share and nindy-share subdirs
2310 properly when building gdb.tar.Z.
2312 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2313 printed in various places, so I could change just one copy.
2315 * dbxread.c, coffread.c: Change references to bfd->iostream
2316 to cast to FILE *, now that BFD avoids needing types defined
2317 in other header files.
2319 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2321 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2322 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2323 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2324 (actually gcc -Wall).
2326 * dbxread.c: Remove first_global_sym, last_global_sym, since
2327 they are never referenced.
2329 * defs.h (baud_rate): Declare.
2330 main.c: Define it, and add the -b option to set it.
2332 * gdb-int.texinfo: Add text on how to define a new host or target
2333 architecture, prompted by Per Bothner's questions about MIPS
2336 * gdb.texinfo: Document "complaints". Change doc of -q since
2337 gdb no longer prints the copyright and blurb if you specify a file
2338 name to be debugged (just like Emacs). Add doc for Nindy-specific
2339 command line flags for specifying target serial port and such.
2340 Update copyright to 1991.
2342 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2343 has taken over for us the job of ripping up executable files. The
2344 crud caused Per Bothner's port to not compile.
2346 * infrun.c (normal_stop): Avoid printing "Program exited
2347 normally" if we are in batch mode. This allows a GDB which
2348 executes a program on a target system, to behave like a Unix
2349 command (input from stdin, output to stdout, no extraneous
2352 * main.c (main): Allow additional machine-dependent command line
2353 options to be specified with the ADDITIONAL_OPTIONS,
2354 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2355 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2356 processing to occur just before the main loop with
2357 BEFORE_MAIN_LOOP_HOOK.
2358 (main): If a "core file" argument is specified, and it is not a
2359 core file, try it as a process ID to attach.
2360 (symbol_completion_function): Attempt to cope with
2361 "show screen-" TAB, not very successfully. This needs more work,
2363 (batch_file): New function, returns whether we are reading
2364 commands from an interactive tty on stdin, or from somewhere else.
2365 Called by normal_stop since it doesn't get from_tty passed down
2366 to it like many commands do.
2368 * remote-nindy.c: Handle command line options for nindy
2370 (nindy_before_main_loop): Prompt user for tty name if they
2371 don't specify it before getting to the interactive command loop.
2373 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2374 and -r command line options. Also add hook before main loop
2375 to make it easy to specify a tty.
2377 * TODO: More things to do, one done.
2379 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2381 * dbxread.c: Make complaint() calls pass pointer, not struct.
2382 Add complaints about badly formatted C++ type information
2383 (const/volatile indicator, and parse errors resulting in
2384 error_type). Fix C++ virtual member fn comment.
2385 (read_struct_type): Avoid bumping pointer if we got a parse
2386 error; this prevents our walking beyond the end of a string.
2387 Terminate loop on null char as well as semicolon.
2388 (process_one_symbol): Fix the LBRAC fix so that it uses the
2389 last previous SLINE, FUN, or SO record's PC address. C++ debug
2390 symbols did not have SLINE records in a useful order compared
2391 to the LBRAC records.
2392 (define_symbol): Handle "catch" records.
2394 * symtab.c (check_stub_type): Added new complain
2395 `stub_noname_complain' and added a consistency check to
2396 keep the debugger from crashing when finishing from an
2397 exception frame. A real fix will be needed later.
2399 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2401 * infcmd.c (attach_command): Make global.
2403 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2404 but make them easy to comment out. Perhaps later they should
2405 be enabled by what CPU you configure for? FIXME.
2406 (VERSION): Roll to 3.93.
2407 (pinsn.o): Remove rule for obsolete file.
2408 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2410 Run down a problem that manifested by printing the wrong function
2411 name in stack traces of read_ofile_symtab. Turned out that the
2412 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2413 the LBRAC symbol with an address in the *data* segment, which
2414 blew our binary search through the blocks.
2416 * dbxread.c: Use the complain() facility consistently to bitch
2417 about problems in the symbol file we are reading.
2418 (finish_block): Add code to check the nesting of the blocks;
2419 complain and Procrust them to fit if wrong.
2420 (make_blockvector): Check the order of the blocks, complain
2421 [but don't cope] if wrong.
2422 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2423 symbols to be sure their PC value is greater than the last SLINE
2424 (line number) symbol we've seen, complaining and adopting the
2425 SLINE PC value if wrong.
2427 * symfile.h (struct complaint, complaint_root, complain,
2428 clear_complaints): Add.
2429 * symfile.c (complain, complaint_root, clear_complaints): Add
2430 facility to deal with non-fatal complaints and to regularize their
2432 (symbol_file_add): Clear complaint counters to allow new complaints.
2433 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2435 * dbxread.c (dbx_symfile_read): Remember the address and size
2436 of the string table for the main symbol file, so we won't read it
2438 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2439 to avoid reading the string table yet again. Lint.
2440 (throughout): Improve filtered output, including word wrap.
2441 (read_range_type): Improve Bothner's fix to handle other types too.
2443 * utils.c: Improve line wrap implementation. Handle unlimited
2444 width by making chars_per_line unsigned.
2445 (puts_filtered): New, easy, function.
2447 * defs.h (puts_filtered): add.
2449 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2450 call the identical sort_symtab_syms() in symfile.c instead.
2452 * expread.y: Suggest the `file' command rather than `symbol-file'.
2454 * command.h (enum var_types): Add zinteger for seroable
2456 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2457 nested if's into a switch.
2459 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2460 we did not stop because of a breakpoint (it must have been for
2461 some other reason, like a "stepi"), so don't print anything.
2463 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2464 doesn't include <sys/types.h>, old SunOS's require it for
2467 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2469 A test port of gdb-3.92.6 to the Sony NEWS.
2472 Don't normally link in remote- or vx stuff.
2473 Some of it doesn't compile, and it wastes space for 99% of the users.
2474 Remove reference to no-longer-used HAVE_VPRINTF.
2475 Fixed BFD_DEP typo to BFD_DIR.
2477 Fix cast in arg to bfd_h_getlong.
2478 Make char *prefix be const.
2479 Fix how certain range types are mapped into builtin unsigned int types.
2481 Remove 2 #includes. They cause errors (on Sony, at least),
2482 and aren't needed (they wern't in earlier versions).
2484 print_address_symbolic should never demangle labels
2485 (since it prints *assembler-level* labels).
2487 [This was superseded by the change to printcmd below.]
2490 Add some "volatile" return types to avoid warnings.
2491 If MISSING_VPRINTF add vprintf function and not just macro
2492 (since vprintf is used in printcmd.c).
2494 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2495 (The latter isn't grokked by some PCC-based compilers.)
2497 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2499 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2500 * nindy-share/coffstrip.c
2501 Added some forward declarations (otherwise, gcc complains
2502 about implicit extern redefined as static).
2504 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2506 Changes inspired by Per Bothner:
2507 * printcmd.c (print_address_symbolic): Take additional parameter
2508 specifying whether to demangle.
2509 (print_address): Pass in asm_demangle to control demangling.
2510 (print_address_demangle): New fn, takes explicit arg to control
2512 * utils.c: Add new vars demangle and asm_demangle, and let them
2514 (fputs_demangled): If !demangle, just print the argument.
2515 (fprint_symbol): If !demangle, just print raw symbol.
2516 * valprint.c (val_print): Call print_address_demangle rather than
2517 print_address, to cause demangling to depend on the global
2518 rather than assembler-level demangling setting.
2519 * WHATS.NEW, gdb.texinfo: Document.
2521 * main.c (show_command): Show all settings if no arg.
2522 (initialize_main): Make "info set" the same as naked "show".
2523 * command.c (cmd_show_list): Handle prefix commands in the
2524 list, and print the name of the setting as well as its English
2525 description and value.
2527 Allow gdb functions to specify where a line should wrap if it
2528 exceeds the size of a terminal line. Use it to make the output
2530 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2531 of the right size when screen width changes.
2532 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2533 (wrap_here): New fn, indicates a point in the output where we
2534 should wrap the line rather than just letting it overflow at a
2536 (fputs_filtered): Implement wrapping.
2537 (n_spaces): New fn, returns a pointer to N spaces.
2538 (print_spaces_filtered): Use n_spaces.
2539 * defs.h (n_spaces): Declare.
2540 * stack.c (print_frame_info): Wrap with 4-space indent after
2541 fn name and before filename and line number.
2542 * printcmd.c (print_frame_args): Wrap with 4-space indent
2543 before each argument name is printed.
2544 * valprint.c (value_print): Wrap with no indentation before
2546 (val_print_fields): Wrap with indentation relative to nesting
2547 level before each field name.
2548 (val_print): Wrap with nesting indentation before array elements.
2549 * command.c (do_setshow_command): Avoid extra newlines,
2550 wrap with 4-space indent around values printed, end with period.
2551 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2553 * breakpoint.c (breakpoint_1): Implement addressprint for
2554 "info breakpoints" display. Change file name and line number
2555 format to " at file:nnn" rather than " (file line nnn)".
2556 * gdb.texinfo: Document.
2559 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2561 Frozen for gdb-3.92.6 release.
2563 README, WHATS.NEW: Update for 3.92.6 release.
2565 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2566 coffread.o from configs since it is now built by default.
2567 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2568 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2569 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2570 from configs since it is now built by default.
2572 Makefile.dist: Update for release 3.92.6. Handle files that
2573 have been moved to ../include, ../getopt, or ../bfd. Add
2574 saber.suppress and tests directory. Add config.status to
2575 the release (it will say "none").
2577 coredep.c: Minor formatting fixes.
2579 These changes were made in early December but only checked in now:
2580 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2581 nindy-share/nindy.c: lint
2582 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2583 register values coming back from the target; we store values
2584 in target byte order everywhere.
2586 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2588 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2590 * valprint.c (cplus_val_print, val_print_fields): New functions,
2591 which print C++ objects. They conspire to avoid printing a
2592 virtual base class more than once, following all the twists and
2593 turns of C++ virtual base rules.
2594 (val_print): Call the above rather than do it by hand.
2596 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2597 symbol file, not for added files like shared libs. This really
2598 needs to be generalized to a timestamp per file.
2600 * core.c (cleanup_core): Avoid coredump if no core file.
2602 * config.gdb: Accept -host or -target in place of +host or
2605 * coffread.c (find_linenos): Avoid desupported BFD interface
2606 to line numbers. We still read them manually rather than using
2607 BFD's "generic" features.
2609 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2611 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2613 * Makefile.dist: Eliminate use of $< in explicit targets.
2615 * readline/Makefile: Use $< rather than $*.c, which does not
2616 include the VPATH in GNU Make.
2618 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2619 copies of tconfig/i960, added for global configuration
2620 compatability. All i960 versions can read both coff and b.out.
2622 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2623 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2626 * TODO: Think of more things to do.
2628 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2630 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2631 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2632 64-bit float conversion.
2634 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2635 equivalent to sun?os4 so global config works.
2637 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2639 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2641 * main.c: Only declare linesize once; declare pagesize not at
2642 all, since it is never used.
2643 (main): Clear newly allocated line before it is used.
2645 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2647 Further stabilization for the Intel 960.
2649 * Makefile.dist: Parameterize the location of the "include"
2650 and "bfd" directories, as well as "getopt". Add symfile.c.
2651 Link in both dbxread and coffread. Fix up "make depend" to
2652 rewack the locations of include, bfd, and getopt in its output.
2654 * README: Document moving include files, improve some of
2657 * coffread.c: Move common code out to symfile.c. Change
2658 symbol_file_command style interface to use new *_symfile_init
2659 and *_symfile_read interface under BFD. Use BFD internal
2660 info to locate line table, symbols, etc.
2662 * core.c (core_fetch_registers): Rename to get_core_registers
2663 to avoid confusion with fetch_core_registers.
2664 (register_addr): Move to coredep.c, which is already machine
2665 dependent. This leaves core.c pretty clean of dependencies.
2667 * coredep.c (register_addr): Accept this routine from core.c.
2669 * dbxread.c: Move common code (with coffread.c, etc) into new
2670 symfile.c. Each psymtab now contains a pointer to the
2671 format-dependent function that knows how to read it in. Make
2673 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2674 (process_one_symbol): Add code to complain about a "compiler bug
2675 we muzzle here", if we actually see it.
2677 * eval.c (evaluate_subexp): Insert missing "break" statements
2678 in code that determines whether a variable is an lvalue in
2679 memory, register, or whatever. I detected this via a compiler
2680 bug in which it *almost* mashed out the whole switch statement.
2682 * gdb-int.texinfo: Add minor sections on configuring gdb for
2683 release, and about the README file.
2685 * infcmd.c (registers_info): Fix formatting somewhat. Still
2686 not as pretty as before, but it handles byte swapping.
2688 * remote-nindy.c: If data cache routines are interrupted while
2689 waiting for the remote end, be sure that any uninitialized cache
2690 blocks are on the free list, not on the valid list!
2692 * symfile.h: Flesh out this header file with all the various
2693 routines and variables that have been merged in from dbxread.c
2694 coffread.c, and symtab.c to symfile.c.
2696 * symfile.c: New file, containing code common to dbxread.c,
2697 coffread.c, and some code from symtab.c. All generic code for
2698 reading symbol files should be in here now.
2699 (unrecord_misc_function): Remove unused function.
2701 * symtab.h: Remove file-reading things to symfile.h.
2703 * symtab.c: Remove file-reading things to symfile.c.
2705 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2706 to decode i960 fault types.
2708 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2709 target.c: Change type of the "resume" function from int to void,
2710 since its result was never used.
2712 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2714 * main.c: Replace "stupid" with "caution"; you now "set caution
2717 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2719 * infcmd.c (do_registers_info): Call val_print to deal with the
2720 byte order of the registers being printed. FIXME, this makes
2721 the formatting of the output uglier.
2723 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2724 defined, call it for signals the debugger doesn't itself use.
2725 The i960 uses this for more detailed fault information.
2727 * remote.c (remote_open): If arg is null, print help rather than
2730 * sparc-xdep.c (register_valid): Avoid declaring size, since
2731 various modules will think of various sizes depending on the
2732 architecture of their tm-file. FIXME, we need protection against
2733 actually entering one of those modules, which would clobber
2734 storage if not for the target architecture compiled into gdb.
2736 * stack.c (up_command, down_command): Always print the frame
2738 (up_silently_command, down_silently_command): New commands
2741 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2743 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2744 more parameters than it used to.
2746 * findvar.c (registers): Increase slop to 256 bytes, which should
2747 protect us against even most RISC machines with large register
2749 (locate_var_value): Move declaration inside related ifdef.
2751 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2752 throughout, to avoid throwing away buffered input from the board.
2753 (nindy_wait): Supply_register takes addr_of_value, not value.
2754 (i960_print_fault): Renamed from i80960_fault.
2755 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2756 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2758 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2759 we can set the PC in the call to proceed(). Unpush nindy_ops
2760 before pushing it on top, to avoid message to user. Eliminate
2761 commentary from Unix machines that just misleads here.
2762 (reset_command): Fix error message to suggest target command.
2764 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2766 Release 3.92.5 as frozen.
2768 Stabilize the merged release...with help from lint, Saber C,
2771 Everywhere: Add include files needed to declare return types
2772 of functions called.
2774 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2776 * breakpoint.h: Add undeclared breakpoint functions, and some
2777 functions for display handling since I couldn't think of a better
2780 * breakpoint.c (insert_breakpoints): Make code for disabling
2781 shared library bkpts more likely to work. It's used when we
2782 rerun a program and stop before the shared library has been
2784 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2785 cast from pointer, so it squeezes through catch_errors.
2786 (bpstat_stop_status): Fix logic broken some time ago. We now
2787 always create a bpstat if the stop address matches a breakpoint,
2788 even if we don't stop there -- just like the old code used to do
2789 before I got my fingers into it (sigh).
2790 (breakpoint_1): Print "ignore count" after "stop only if"
2791 condition, since that's how it actually works.
2792 (mention): Handle watchpoints as well as breakpoints.
2793 (watch_command): use set_raw_breakpoint and mention to do most
2794 of the work (and initialize all the fields!). Only pass one
2795 arg to parse_c_expression, since that's all it takes.
2797 * command.c (not_just_help_class_command): Rename arg to args
2798 since we ignore "unused argument" warnings on vars named "args".
2799 inflow.c (child_terminal_info): ditto.
2800 infptrace.c (kill_inferior): ditto
2801 main.c (catch_errors, version_info, quit_command, pwd_command,
2802 source_command, dump_me_command, editing_info,
2803 set_history_size_command, set_history, show_history,
2805 stack.c (locals_info): ditto
2806 target.c (target_files_info): ditto
2807 valprint.c (set_input_radix, set_output_radix): ditto
2809 * core.c: Remove old variables for handling core and exec file
2810 sections (data_start, data_end, stack_start, stack_end,
2811 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2812 text_end, exec_data_start, exec_data_end, text_offset,
2813 exec_data_offset, data_offset, stack_offset). They're
2814 superseded the more general build_section_table and
2816 (get_exec_file): Mention the `file' command.
2817 (read_memory_check): Rename to memory_error, and only call it
2818 in the case of an actual error.
2819 (read_memory, write_memory): call memory_error.
2820 (core_fetch_registers): Register section name is ".reg".
2822 coredep.c: Remove a bunch of crud now that all this file does
2823 is pull the registers out of a core file.
2824 (fetch_core_registers): Rewrite to actually work, I hope.
2826 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2827 Replace index() with strchr(). Remove all the pre-BFD macro
2828 definitions for accessing the symbol file.
2829 (struct dbx_symfile_info): Encapsulate the information that
2830 dbx_symfile_init needs to pass to dbx_symfile_read in this
2833 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2834 dbx_symfile_discard): Rearrange symbol file reading to divide
2835 the format-specific part from the format-independent part,
2836 leaving the format-independent part such as file name expansion
2837 and opening in symtab.c. This replaces
2838 partial_symbol_file_open and partial_symbol_file_read.
2839 Symbol_file_read, add_file, add_file_target_command,
2840 add_file_addr_command move to symtab.c. Pass an explicit
2841 "mainline" flag for when reading the main symbol table, rather
2842 than relying on the offset address to be zero or nonzero.
2844 (dbx_symfile_read): Don't allow void *'s to be printed as
2846 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2847 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2848 macro" debug version really work.
2849 (read_dbx_symtab): Remove unref'd parameter inclink.
2850 Avoid swapping N_SLINE symbols, for speed.
2851 Merge N_TEXT!N_EXT case with the other external symbol
2852 definitions' case. Add comments.
2853 (start_psymtab): Allocate the symfile name in the psymtab on
2854 the psymbol_obstack, rather than using the caller's storage.
2855 (end_psymtab): Only allocate a dependencies list if there are
2857 (psymtab_to_symtab_2): Use BFD when reopening file to read
2858 its symbols for real.
2859 (read_struct_type): Add FIXME comments where it needs work
2861 (read_huge_number): Add FIXME about overflows.
2862 (read_range_type): Add FIXME about comparing a long to 1<<32.
2864 * coffread.c: Minor changes to move things closer to the new
2865 regime with symtab.c and dbxread.c Major work is still needed
2868 * exec.c (exec_file_command): Remove old variables (see core.c
2870 (xfer_memory): If memory transfer is right at the end of a
2871 section, don't lose.
2873 * findvar.c (get_saved_register): If value is in a real
2874 register, LVAL is lval_register, not lval_memory.
2876 frame.h: Declare print_sel_frame and record_selected_frame.
2878 gdb-int.texinfo: New file, for GDB internals documentation.
2879 Very simple, unformatted doc of cleanups is there for now.
2881 gdbcore.h: Remove obsolete variables that described a.out
2882 section addresses and offsets. (See core.c above.)
2883 Declare fetch_core_registers and registers_fetched.
2885 getopt.c: Declare char *alloca(); even on SPARC.
2887 infcmd.c (run_command): Call target_kill rather than
2889 (step_command, next_command, stepi_command, nexti_command):
2890 Declare from_tty parameter even though we don't use it.
2891 (run_stack_dummy): argument BUFFER is a char array, not
2892 a pointer to REGISTER_TYPE.
2893 (finish_command): using_struct_return needed a value *,
2894 not a struct symbol *.
2896 * infptrace.c (child_xfer_memory): To avoid dependency on
2897 where sections are in memory, try PT_WRITE_D and if that fails,
2898 try PT_WRITE_I. Most Unixes don't care which you use.
2900 * infrun.c (step_resume_break_shadow): Change to array to
2901 match other breakpoint shadow storage.
2902 (clear_proceed_status): Pass address of bpstat to
2903 bpstat_clear, not the bpstat itself.
2904 (child_create_inferior): FIXME comment about if the child
2906 (start_inferior): Remove old function.
2907 (child_open): Use target_kill rather than kill_inferior.
2908 (wait_for_inferior): Ditto.
2909 (insert_step_breakpoint, remote_step_breakpoint): Use
2910 new step_resume_break_shadow.
2912 * inftarg.c (child_wait): If all child processes die,
2913 pretend that the one being waited for exited with signal 42.
2915 * main.c (command_line_input): When scanning for comments,
2916 don't coredump on unclosed quotes.
2917 (quit_command): Use target_kill rther than kill_inferior.
2918 (_initialize_main): Rename class_user from "user" to
2921 * printcmd.c (print_command_1): Initialize "fmt" if no format
2922 is specified by the user.
2923 (print_frame_args): Only add to args_printed if we are
2924 actually fetching args from the stack (avoiding undefined
2926 (_initialize_printcmd): Remove bogus \{ from string.
2928 * remote-eb.c (eb_open): Avoid coredump on no argument.
2930 * remote-nindy.c: Bring out of Intel environment into new
2931 target environment. Remove all conditional compilation on
2932 I80960. Massive hacking throughout.
2933 (nindy_xfer_inferior_memory): New routine stolen from
2935 (nindy_create_inferior): New routine pieced together, probably
2936 not quite working yet.
2937 (nindy_ops): New target_ops struct for nindy.
2939 * remote-vx.c: Use write_memory rather than target_write_memory
2940 to get error checking.
2941 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2943 (vx_create_inferior): Use target_terminal_ours...
2945 * signame.c (_initialize_signame): Always initialize, since
2946 we need the table for things other than psignal.
2948 * solib.c (solib_add): Use symbol_file_add, not add_file.
2949 (solib_address): Return boolean result rather than struct
2950 pointer which nobody else knows the type of.
2952 * sparc-tdep.c, valops.c: Use write_memory rather than
2953 target_write_memory, to get error checking.
2955 * stack.c (locals_info, catch_info, args_info,
2956 get_selected_block, frame_command, up_command): Use
2957 target_has_stack, rather than have_inferior_p or
2960 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2962 * symfile.h: New file, defining the interface between the
2963 generic and object-file-specific symbol reading code.
2965 * symtab.c: Move generic symbol-reading interface to symtab.c,
2966 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2967 table to map BFD targets to symbol-reading modules in GDB.
2968 Change index to strchr.
2969 (lookup_struct_elt_type): Use error() rather than hand-made
2970 simulations thereof.
2971 (lookup_partial_symbol): Speedup slightly when length == 0.
2972 (symbol_file_add): New function.
2973 (symbol_file_command): Call it.
2974 (symfile_open, symfile_init): New function.
2975 (add_file_target_command, add_file_addr_command): moved from
2978 * target.c (target_command): use target_kill.
2980 * target.h (target_files_info): Don't declare, never called
2983 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2984 files to determine stack end address.
2986 * valarith.c (value_x_binop, value_x_unop): Change error message
2987 to be more useful. Pass proper argument to value_struct_elt.
2989 * valops.c (value_assign): FIXME comment that long long
2990 bitfields will break here.
2992 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2993 Update `make saber_gdb' to work better.
2995 * TODO: A woman's work is never done.
2997 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2998 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2999 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
3000 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
3001 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
3002 valops.c, valprint.c, exec.c: Lint.
3005 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
3007 Continuing Intel 960 port merge of GDB.
3009 * Makefile.dist: Merge i960 "nindy-share" files. Rename
3010 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
3011 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
3012 Wack over "make depend" so it handles files in subdirectories
3013 vx-share, nindy-share, bfd, and in the current directory.
3015 * blockframe.c (get_prev_frame_info): Remove fatal error
3016 if stack not defined.
3018 * core.c (core_open, core_detach): New functions that handle
3019 the old "core-file" command as "target core" and "detach" instead.
3020 (core_file_command): Call them.
3021 (core_xfer_memory): Use common routine xfer_memory.
3023 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
3024 dbxread now uses bfd for everything but symbol reading itself.
3025 BFD internals are used to drag out the relevant file offsets.
3026 (partial_symbol_file_open): Change args all around for BFD.
3028 * symtab.c: Rename "value" to "val" everywhere, so we can
3030 (symbol_file_command): New command, moved from dbxread.c
3031 and coffread.c. It uses BFD to read the file, then vectors
3032 based on its type, to dbx or coff symbol readers.
3033 * symtab.h: Extern a few vars for symbol_file_command.
3035 * target.h: Breakpoint takes a char * save area, not a char **.
3037 * valprint.c (val_print): When unpacking bitfields, offset
3038 the address in gdb of the value, if it is declared with a shorter
3039 type. Remove the last "runtime kludge test" of host byte order.
3041 * utils.c: Remove old my_bfd_read routine.
3043 * stack.c (frame_info): Use target_has_stack. Print program counter
3044 register's actual name rather than "pc", since it's called the
3045 "ip" (instruction pointer) on the i960 (sigh).
3047 * target.c (target_command): Add command for selecting a target
3048 type and calling its open routine. This is used for initiating
3049 communication with a particular target, in a generic way.
3051 * tm-i960.h: Update for modern gdb. Remove semicolons from
3052 various macros. Handle reading struct return convention, and
3053 error-out attempts to return structs with the "return" command.
3054 Be sure gdb doesn't think we know how to call functions in the
3057 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
3058 to i960_xxx in lower case.
3059 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
3060 not being defined yet.
3062 * remote.c (remote_open): Call start_remote to initialize
3063 wait_for_inferior during open.
3064 (remote_xfer_inferior_memory): Return length written rather
3067 * remote-vx.c (target_command -> vx_open): Use new generic
3069 * remote-eb.c, inftarg.c, exec.c: ditto.
3071 * infrun.c: Fix comments.
3072 (attach_program -> child_open): Use new generic target command.
3073 (wait_for_inferior): Clear saved register values before target_wait,
3074 so target_wait can set some of them if convenient.
3076 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
3077 Return success indicator, not void.
3078 (child_xfer_memory): Avoid fetching initial word if we'll
3079 overwrite it anyway.
3081 * infcmd.c (attach_command): Use new generic target open routine.
3082 (_initialize_infcmd): Update doc on attach and detach commands.
3083 (do_registers_info): Merge in a byte-order problem as a FIXME
3086 * findvar.c (find_saved_register): Avoid problem in current frame.
3087 (read_relative_register): Ditto.
3088 (write_register): Convert byte order on the way out.
3090 * exec.c (file_command): Add.
3091 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
3092 (xfer_memory): Common function between core_xfer_memory and
3094 (exec_xfer_memory): Use it.
3096 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
3098 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
3099 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
3100 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
3102 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
3104 Merge Intel 960 port of gdb, continuing...
3106 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
3107 symbol_file_command): Pass from_tty arg to hush 'em up.
3109 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
3110 Add magic numbers for 960 COFF format.
3112 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
3114 Merge Intel 960 port of gdb, from Intel "1.2" release.
3116 CHANGE_LOG entries from their port, which was based on
3119 Thu Sep 6 11:02:22 PDT 1990
3120 Remove temp file if download is interrupted.
3122 Wed Aug 1 09:08:33 PDT 1990
3123 Now uses binary protocol to talk to NINDY.
3124 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
3125 Times out after 5 seconds when trying to talk to NINDY.
3127 Tue May 29 12:54:49 PDT 1990
3128 Added variable baud rate (-b switch).
3129 Source code reorganization.
3131 Thu Apr 26 11:09:55 PDT 1990
3132 More cleanup of batch mode; specifically, execute "-s", "-e", and
3133 "-se" switches as soon as they are encountered on the invocation line.
3135 Fri Apr 20 13:47:15 PDT 1990
3138 Thu Apr 19 09:54:28 PDT 1990
3139 Add 'reset' command.
3141 Wed Apr 18 09:48:07 PDT 1990
3142 After opening remote tty, wait for 1 second to go by without input
3143 from it before trying to talk to NINDY (fixes problems with the
3144 Heurikon HK80/V960E).
3146 Mon Apr 4 16:33:05 PDT 1990
3147 Some output was not being suppressed in 'batch' mode.
3149 Thu Mar 22 15:31:11 PST 1990
3150 Ask user if old symbol table should be deleted when new file is
3153 Allow user to run a program downloaded before gdb960 was brought up.
3155 Correct "exec-file" help message for i80960 context.
3157 Correct bug in calculating user space address: could occasionally
3158 corrupt user program.
3160 Make sure to zero low-order bits in rip's because of bug in 960CA
3161 A-step part: could cause operation faults when "next"ing across
3164 Correct bug that made it impossible to get source line numbers for
3165 code loaded at addresses higher than 0x7fffffff.
3167 Wed Jan 10 12:43:22 PST 1990
3168 Open remote tty for exclusive use.
3170 Fri Jan 5 12:14:42 PST 1990
3171 Correct disassembly (CA manual was right after all):
3172 opcode for sysctl is 0x659
3174 Mon Oct 23 12:03:04 PDT 1989
3175 Use G960BASE and G960BIN environment variables to find 'sx' utility.
3177 Mon Oct 16 14:15:09 PDT 1989
3178 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
3180 Mon Oct 2 15:56:31 PDT 1989
3182 Added 960CA disassembly support.
3184 To simplify maintenance:
3185 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
3187 - eliminated opcode.h: incorporates tables into i960-pinsn.c
3188 - moved 960-specific routines from i960-pinsn.c to i960-md.c
3189 - made disassembly interface identical to that in gdmp960.
3193 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
3195 * target.h: Allow targets to stack. Add target_has_memory,
3196 _registers, etc. Restructure memory access and "info files"
3197 to walk the target stack.
3198 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
3199 target.c: Change tables to match target.h.
3200 * inflow.c (child_mourn_inferior): pop child_ops.
3201 (generic_mourn_inferior): Use new has_stack flag.
3202 * infptrace.c (child_xfer_memory): New memory regime.
3203 * inftarg.c (child_files_info): New "info files" regime.
3204 * remote-eb.c: New memory regime, new info files.
3205 * remote-vx.c: New memory regime, new info files. Now use
3206 separate targets for VxWorks attachment to machine, and
3207 actually running a process under VxWorks, since one has
3208 stack & execution & regs and the other doesn't.
3209 * remote.c: New memory regime, new info files.
3210 * sparc-xdep.c (fetch_core-registers): New memory regime.
3211 * target.c: New routines and support for stacked targets,
3212 new memory regime, new info files regime.
3215 Generalize section handling for an arbitrary number of sections,
3216 including use of the new BFD (binary file) library.
3217 * gdbcore.h: Add struct section_table.
3218 * exec.c (build_section_table): Iterate all sections and
3219 record what gdb needs to know about them.
3220 (exec_command): Use it.
3221 (exec_xfer_memory): Use the table.
3222 (exec_files_info): Print the table.
3223 * core.c (core_file_command, core_xfer_memory, core_files_info):
3225 * source.c (find_source_lines): Use bfd_get_mtime.
3226 * dbxread.c: Quick changes to make it compile with new BFD.
3227 * utils.c (error): Avoid using bfd_error in generic routines.
3229 * core.c (core_fetch_registers): Get from the ".regs" section of
3231 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
3233 * inferior.h (attach_flag): Export.
3234 * infcmd.c (run_command): use new target_create_inferior.
3235 * infrun.c (child_create_inferior): Don't return result.
3236 * Makefile.dist (VERSION): 3.91.4.
3238 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
3240 * breakpoint.c (bpstat_num): Handle breakpoints which have
3241 since been deleted, such as temporary breakpoints.
3242 infcmd.c (program_info): ditto.
3244 * core.c (core_file_command): Display the frame where the core
3249 * remote-vx.c (target_command): Merge in target command from
3250 targ-vx.c. A few other cleanups.
3252 * TODO, Projects: Lots more stuff to do...
3254 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
3256 Massive changes to wall off the remote-debugging interface
3257 behind a function vector. The port to handle VxWorks targets
3258 is also part of this.
3260 All files: Replace references to renamed functions,
3261 remove references to remote_debugging, remove references to
3262 have_include_file, have_core_file in favor of target_has_stack,
3263 target_has_memory, etc.
3265 * Modularize the breakpoint interface.
3266 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
3267 a breakpoint instruction.
3268 breakpoint.c: struct breakpoint's shadow_contents now sized as
3270 (insert_breakpoints): Vector to target to install breakpoints.
3271 (remove_breakpoints): Vector to target here too.
3272 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
3273 sparc-tdep.c (single_step): Use new breakpoint interface for
3274 the single-step breakpoints.
3275 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
3276 New file, contains routines to insert and remove breakpoints by
3277 reading out the old contents and later replacing them. This is
3278 how ptrace breakpoints work, and many remote systems as well.
3280 * tm-vxworks68.h: New config file, overrides a few things for
3281 Wind River's preferences.
3283 * target.h: New file, for transfer vector used to talk to the
3284 inferior (child, attached, core, exec, remote, etc). All accesses
3285 to the thing being debugged should come through these vectors.
3286 target.c: New file, routines to handle transfer vector.
3287 (various files): Add transfer vectors XXX_ops for the various
3288 targets and pseudo-targets (core files, etc) we support.
3290 * breakpoint.c (bpstat_stop_status): Further explorations of
3291 watchpoints and why things don't work all the time.
3292 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3294 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3295 the local gdbinit if it doesn't already have it.
3297 * core.c (core_ops): add and install.
3298 Allow core debugging without exec file.
3300 * dbxread.c (free_and_init_header_files): Merge two fns.
3301 (end_symtab): Free named symbol table when a new version comes in.
3302 (read_dbx_symtab): Relocate all kinds of symbols with base
3303 address. First step toward handling different text, data, bss
3305 (add_file_addr_command): Renamed add_file_command.
3306 (add_file_command): Vector to remote handler.
3307 Add "load" as an alias for "add-file" command.
3309 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3310 non-returning functions.
3312 * exec.c: Add exec_ops, and push it as a target when an exec
3315 * infcmd.c (run_command): Pass executable file name and arg list
3316 separately when starting an inferior. Permit "run" when no exec
3317 file is specified, for VxWorks.
3318 (detach_command): Move to child_detach in inftarg.c.
3320 * inftarg.c: New file. Unix-child-specific routines, and the
3321 child_ops structure.
3323 * inferior.h (registers): Export "registers" as the way for
3324 target dependent register handlers to find gdb's local copy of
3325 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3326 since it is now used by places that want wait_for_inferior to
3327 handle the grunge but want to see every trap from the inferior.
3329 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3330 Eliminate remote_debugging hooks in terminal handling.
3332 * infrun.c: Replace start_inferior with child_create_inferior.
3333 Move all the hair of Unix shells and ptrace idiosyncracies into
3334 child_create_inferior, so remote handlers don't have to deal.
3335 Remove running_in_shell. Rename stop_after_attach to
3336 stop_soon_quietly, and use it in a few other places where we want
3337 to just call wait_for_inferior and get control back on the first
3338 trap. trap_expected now never takes a value > 1.
3339 (init_wait_for_inferior): Initialize static vars when a new
3342 main.c (gdbinit): Add new hook for .gdbinit file name, let
3343 it be overridden by config files as GDBINIT_FILENAME.
3344 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3345 Both of these are used for VxWorks gdb.
3347 mcheck.c: rename include file "gmalloc.c" to avoid problems
3348 with system include file "malloc.c".
3350 param-no-tm.h: New include file, same as param.h but does not
3351 include the default "tm.h" file. This is used in files where
3352 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3354 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3356 remote-vx.c: New file, VxWorks remote debugging support. Uses
3357 RPC routines that are shared with the target system, in directory
3360 remote.c: Vectorize remote interface.
3362 source.c: Globalize source_path, and make an alias "l" for "list"
3363 since we now have the "load" command.
3365 sparc-xdep.c: Use new param-no-tm.h.
3367 symmisc.c (free_named_symtab): Add new function from Wind River.
3368 However, ifdef it out for now while we think about what it should
3371 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3373 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3374 non-Unix-children handle this with their own code in the target
3377 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3378 source and target lists. Add vx-share to default list of include
3379 directories. Add new files to src and target lists: mem-break,
3380 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3381 ${srcdir} versions of munch and createtags are used.
3383 * valops.c (find_function_addr): Split out of call_function.
3384 (call_function_by_hand): Rename call_function; this function
3385 calls functions in the target by laboriously patching the target
3386 word-by-word with the right stack, args, regs, etc.
3389 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3391 Handle AMD 29000 a bit better.
3393 * remote-eb.c (readchar): Mask received char log to make it readable.
3394 (remote_start): Pass arguments down to executing program.
3395 Make startaddr unsigned.
3396 infrun.c (start_inferior): Accept args, pass them to
3398 infcmd.c (run_command): Pass args down to start_inferior.
3400 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3401 the target object file format.
3402 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3404 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3405 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3407 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3409 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3410 * TODO: We did a few things, we have more to do though.
3412 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3413 * inflow.c (inferior_died): Clear deferred stores.
3415 * Debug problems with dummy frames and calls to the inferior.

3418 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3419 (sparc_push_dummy_frame): Simplify and fix what we push.
3420 (sparc_pop_frame): Slightly more hair here, deciding whether
3421 we are restoring a saved PC or returning to a return address in %i7.
3422 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3424 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3425 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3426 * obstack.h (chunkfun): ditto.
3427 * defs.h (xmalloc, xrealloc): ditto
3429 * utils.c (quit): Grab the terminal from the child if necessary.
3431 * inflow.c (term_status_command): Rename to term_info, change
3434 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3435 (is_delayed_branch): Speed up.
3436 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3437 Still missing some float ops, and needs testing.
3439 * Support for input and output radixes other than base 10
3440 * defs.h (input_radix, output_radix): Declare.
3441 * expread.y (yyparse, parse_number): Handle changes of input
3442 radix, and ambiguous names-or-numbers in radixes >10.
3443 * printcmd.c (print_scalar_formatted): Print formatted hex
3444 numbers in varying column widths.
3445 * valprint.c (val_print): Use output_format to print scalar ints.
3446 (set_input_radix, set_output_radix, set_radix): Create.
3447 (set_output_radix): Set output_format from output_radix.
3448 (_initialize_valprint): add `set radix' but leave the others off.
3450 * main.c (execute_command): Let stupid questions be turned off.
3451 (_initialize_main): Handle "set stupidity", etc.
3453 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3454 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3456 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3458 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3459 bfd stuff is still screwed up, but with some manual work, it
3462 * breakpoint.c (bpstat_do_actions): Start over if a command
3463 proceeds the inferior, since the inferior will have stopped and
3464 will need to have its new stop-actions taken care of.
3466 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3467 compiler fits, simplify it.
3469 * gdb.texinfo (directory command): Doc new dir command.
3470 source.c (directory_command): "dir" now puts things on the front
3471 of the path, moves dups up front, and handles multiple names
3472 on the command line, inserting each one in order. It also
3473 blows away cached line and full_filename info.
3475 * stack.c (backtrace_command): Skip "more stack frames follow"
3478 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3479 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3480 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3481 The only odd one was Gould NP1, which had defined vprintf to
3484 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3485 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3486 variable, inspect_it.
3487 valprint.c (print_string, val_print): Use the global inspect_it
3488 to indicate whether to print in Epoch style or normal style.
3490 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3492 * printcmd.c (call_command): add an alias for the "print" command
3493 which runs expressions and doesn't print the result if void.
3494 (print_command_1): implement it.
3496 * command.c: Remove #if 0'd code. Initialize all the fields
3497 in add_cmd (). Rename do_nothing_command to
3498 not_just_help_class_command, and make it externally visible.
3499 command.h: add user_commands to struct.
3500 * main.c (define_command): Don't overload c->function with a char
3501 string as well as a function pointer.
3503 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3504 calling convention of value_struct_elt () that got dropped in
3507 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3508 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3510 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3512 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3513 until a good time (e.g. when we are about to run the child),
3514 saving ptrace calls.
3515 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3516 * tm-sparc.h: define DO_DEFERRED_STORES.
3518 * sparc-xdep.c (store_inferior_registers): when storing float
3519 registers, don't store stack regs too. When storing the SP,
3520 however, DO store the stack regs too. This fixes a bug in which
3521 the dummy frame is not recognized when a call_function finishes,
3522 because its frame pointer (in the stack regs) was never
3524 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3525 even though we don't know how to read them from an inferior.
3526 valops.c (call_function): Comment about storing SP.
3528 * infrun.c (save_inferior_status): Save away the original bpstat
3529 chain so it can be restored later. Install the copied version for
3530 use by whoever saved the status. It will be blow away by
3531 restore_inferior_status, and the original chain restored. This is
3532 important for people who have pointers into the original.
3534 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3535 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3536 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3539 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3541 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3542 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3543 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3545 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3547 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3548 Store the baseclasses in a type struct starting from array element
3549 0 rather than from the unusual array element 1.
3551 dbxread.c: the above.
3552 (virtual_context): Add
3553 Read new debug information about which virtual function table
3554 a virtual function is from, and store it in fn_field.fcontext.
3556 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3557 TYPE_FN_FIELD_STATIC_P.
3559 symtab.c: the above.
3560 valops.c: the above. Handle pointer casts of object *'s.
3561 (search_struct_method): Add.
3562 (value_struct_elt): First arg is now a pointer to a value, and is
3565 valprint.c: the above.
3566 values.c (value_virtual_fn_field): Add type arg. Handle
3567 offsetting to the proper object when calling virtual fns.
3569 (baseclass_addr): Add valuep arg.
3571 * README: Document the current state of BFD config (missing).
3572 * TODO, ChangeLog, Makefile.dist: Roll version.
3573 * WHATS.NEW: Add summary of changes since 3.5.
3575 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3577 * dbxread.c (read_struct_type): Clear bit vectors whenever
3579 symtab.c (B_CLRALL): define.
3581 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3582 using == rather than =. Huh... This fixes the dreaded problem
3583 wherein builtin_type_int becomes TYPE_CODE_FLT.
3585 * core.c (info_files): Show the inferior pid.
3587 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3588 already knows how to look in the source directory.
3590 * Remove psymtab hair from many places. Remove duplicated code
3591 for searching symbol tables. Hide psymtabs from most places.
3592 Make it fast to get from a psymtab to its symtab.
3594 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3595 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3596 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3597 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3598 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3599 new symtab completely. New psymtabs get symtab pointer
3600 initialized to zero. Remove MI warning printf.
3601 symtab.h: Comments. Add psymtab to symtab pointer.
3602 (PSYMTAB_TO_SYMTAB): New macro.
3603 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3604 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3606 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3608 (print_frame_info): Avoid special-casing symbols that have not yet
3611 * source.c (open_source_file): Quick path if we have already
3612 located the source file by its full name.
3614 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3615 find_pc_psymtab. When a name is found in the misc function
3616 vector, search the symbol table for its mangled name, not the
3617 name that the user typed.
3619 * bfd.h: Fix missing comment terminators, make #endifs match.
3621 * valarith.c (value_less): Handle unsigned int comparisons.
3622 Add FIXME about pointer compares, which assume host and target
3623 pointers are the same.
3625 * command.c (do_nothing_command): lint
3626 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3627 fix comments on debug symbol format for visibility. Actually set
3628 visibility of symbols.
3629 main.c (echo_command): lint; use <readline/history.h>.
3630 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3631 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3632 pointing past end of allocated memory; saber complains.
3633 obstack.h: Declare the external functions that we use.
3634 valarith.h: use <string.h>
3635 solib.c (solib_add): lint.
3637 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3639 * main.c (initialize_main): Default info_verbose to off, now that
3640 symbol reading is fast.
3641 (quit_command): Avoid clobbering exec_bfd while quitting.
3643 * Initial BFD (binary file diddling library) merger:
3644 coffread.c: Change AOUTHDR to struct exe_hdr.
3646 core.c: initialize initialized data at compile time.
3647 (core_file_command): Move from coredep.c, convert to bfd.
3648 (xfer_core_file): Convert to bfd.
3649 exec.c (exec_file_command): use bfd routines.
3651 mips-tdep.c: Remove exec_file_command and friends.
3654 * coredep.c: (fetch_core_registers) Convert core_file_command to
3655 fetch_core_registers.
3656 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3658 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3659 (my_bfd_read): More bogosity, which I don't think we call.
3660 (program_name): Remove this atrocity asap!
3662 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3665 values.c: allocate_repeat_value was not clearing the
3666 optimized_out field.
3667 (value_static_field): minor stylistic fix (wrong macro was used).
3668 valops.c (value_struct_elt_for_address): didn't work for C++
3671 * signame.c (_initialize_signame): Initialize signal names once.
3673 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3674 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3675 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3677 * remote-eb.c: Support user-settable baud rates on the serial port.
3679 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3681 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3683 * tconfig/sun3os4: Remove warning about native assembler,
3684 since it also occurs in the xconfig file.
3686 * findvar.c (registers): Allocate some slop after `registers'
3687 to prevent stray accesses from trashing the next variable.
3689 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3690 on the sun-3, by changing the #ifdef from `sun3' (which is not
3691 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3692 vars, which happened to follow `registers' in the executable.
3694 * readline/history.c (history_search): Heed gcc-2's advice
3695 and parenthesize && inside ||).
3697 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3698 tm-29k.c: Insert FSF copyright headers.
3700 * remote-eb.c: Better comments.
3702 * Makefile.dist: Update to 3.91.6.
3703 * TODO: note PREPARE_TO_STORE problem.
3705 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3707 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3709 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3711 * infrun.c (wait_for_inferior, at end): Don't set up
3712 prev_* if the inferior no longer exists.
3714 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3715 CANNOT_EXECUTE_STACK.
3716 valops.c (call_function): Use it.
3718 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3720 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3721 infrun.c (wait_for_inferior, 2 places): Use it.
3723 * values.c (value_being_returned): Only use
3724 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3726 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3727 right thing for remote-eb.c.
3729 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3730 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3732 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3733 (FRAME_FIND_SAVED_REGS).
3735 * findvar.c ({fetch,store}_registers): Check for
3736 REMOTE_{FETCH_STORE}_REGISTER macro.
3738 * findvar.c (get_saved_register): Add argument lval and
3739 change meaning of argument addr.
3740 findvar.c: Change calls to get_saved_register to reflect
3741 new calling convention.
3742 valops.c (value_assign): Use get_saved_register instead of
3743 find_saved_register.
3745 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3747 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3748 an (uninitialized) pointer to one. Use "&" when passing it
3751 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3753 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3756 * coffread.c (symbol_file_command): Put semicolon after
3758 Put safe_to_init_tdesc_context in #if defined (TDESC).
3759 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3760 coffread.c: #include <sys/stat.h>.
3761 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3762 Add missing ')' in check for "lc%" and friends. Remove
3764 Declare read_one_sym() at top of file.
3765 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3766 MC68WRMAGIC can have the same value without causing a duplicate
3769 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3771 * Allow a Makefile to be built without building the
3772 tm and xm file links that screw up builds in subdirectories.
3773 This is done with `config.gdb none', then you can do things
3774 like `make gdb.tar.Z'.
3775 * tconfig/none: Config file for no target system
3776 * xconfig/none: Config file for no host system
3777 * config.gdb: If no TM or XM files are called out by the
3778 host or target file, don't make links for them.
3780 * cplus-dem.c: Add documentation.
3782 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3783 simple error, so the user's gdb doesn't crash due to some object
3784 file problem (e.g. somebody is rebuilding the file out from under
3787 * printcmd.c (print_address_symbolic): demangle the symbol.
3789 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3790 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3791 (alldeps.mak): sort and uniq all results from this; duplicates
3792 hose gdb.tar.Z link building. Remove RCS files from
3793 tconfig and xconfig. Add config files for sun386. Add
3794 a few odd files to OTHERS and HFILES.
3796 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3798 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3799 Roll version number to 3.91.5. Make lint work in bindir.
3801 * README: Document cross-debugging and new file structure.
3803 * blockframe.c: Lint. Include "value.h" to declare read_register.
3804 (find_pc_partial_function): remove duplicate line.
3806 * command.h: Lint. Declare error_no_arg and dont_repeat.
3808 * tm-news.h: Remove inadvertently duplicated stuff.
3810 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3811 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3813 * config.gdb: Allow `config.gdb host target' form. Clean
3814 up previous change that printed bogus messages when you just said
3817 * core.c: #include "command.h" for lint.
3820 * main.c: Remove some casts of enums. Lint.
3827 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3829 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3830 read it from memory. This will allow us to save ptrace calls
3831 eventually. Changed caller single_step too.
3833 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3834 that we aren't going to use, saving many ptrace calls, especially
3835 when watchpointing or single stepping. Use some #define's for
3837 (store_inferior_registers): Ditto.
3838 (core_file_command): Use some #define's for constants.
3840 * tm-sparc.h: Add #define's for some register numbers, so we
3841 can eliminate the use of random constants in sparc-xdep.c.
3843 * stack.c (frame_command, print_frame_info, up_command,
3844 down_command) Remove frame_changed, since it
3845 causes a bug and doesn't seem to do anything useful. In some
3846 places it was used as a flag, in others as a stack level (?).
3848 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3849 default is to use the portable (vprintf) version rather than the
3851 * xm-news.h (MISSING_VPRINTF): Add.
3853 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3855 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3857 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3858 about linking debugged programs -Bstatic in the sun?os4 config
3859 files in tconfig and xconfig subdirectories.
3861 * main.c (main): Remove unreached exit(0) now that we exit
3864 * Create TODO file for online bug list. There are too many
3865 "little" bugs to keep track of on paper.
3867 * Change Projects file to refer to bug-gdb@cygnus.com
3868 rather than kingdon@ai.
3870 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3872 * Makefile.dist (VERSION): 3.91.4 now.
3874 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3875 (condense_misc_bunches): Add sanity check that misc_count is
3876 the same as the number of symbols in the bunch.
3878 * coffread.c: rename init_misc_bunches. Pass an argument
3879 to condense_misc_bunches (a zero).
3881 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3882 every time we are called; don't rely on our caller to do it.
3883 (add_file): Remove call to init_misc_bunches.
3885 * mipsread.c: Only warn, don't error, if unknown symbol types.
3886 This keeps an old gdb from falling on its face if it sees newly
3887 extended symbol info. Rename init_misc_bunches.
3889 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3891 * Merge in changes from Per Bothner for DECstations and other
3892 MIPS stuff. The rest is Bothner speaking:
3894 The next message is a merger of Alessando Forin's mips port with
3895 mine. I've tried to use my good if biased judgment to get
3896 the best of both. It *does* need testing.
3898 Some of the changes are general, *not* mips-specific.
3901 Didn't believe in little-endian bit order.
3902 There are still inconsistencies about whether flags
3903 like BITS_BIG_ENDIAN are integer (#if ...) or
3904 boolean (#ifdef ...). I tried to paper over them.
3906 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3907 Moved some misc_function code that was common to
3908 {dbx,coff,mips}read.c to symtab.c.
3909 In the process, I think I cleaned things up a bit.
3910 At the same time, moved obsavestring and obconcat to symtab.c.
3913 Removed obsolete condense_addl_misc_bunches (use
3914 condense_misc_bunches(1) instead).
3917 Needed to include <sys/dir>, at least on DECstations.
3919 valops.c, mips-tdep.c, tm-mips.h:
3920 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3921 conventions (when STACK_ALIGN is insufficient).
3922 Needed on mips, where doubles need 8-byte alignment,
3923 but ints only need 4.
3926 Removed cruft that was not being used.
3927 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3930 Print $ before register-names (I think that makes things a little
3932 Never print two instructions, even if one delays.
3933 Removed hex-disassemble set_cmd. (This is not mips-specific,
3934 so I think the argument is whether it is generally worthwhile or not.
3935 I'm inclined to think not, given how easy it is to
3936 convert between radixes in gdb.)
3939 This is basically Alessando's code.
3940 It doesn't use obstacks; I changed it to use obstacks
3941 in a few minor places where using malloc causes a
3942 memory leak. (Probably, more places could/should be changed.)
3943 I added record_misc_function where it was missing.
3944 In symbol_file_command and add_file_command, I tried
3945 to make the code consistent with more recent versions.
3946 Minor sylistic changes in parse_procedure.
3947 Make a .gdbinfo. psuedo-symbol point back to the real
3948 procedure symbol (using the isym field).
3951 This is basically from my port, but with a lot of details
3952 and a number of routines merged in from Alessando's version.
3953 I basically used my code "raw" backtrace (use heuristics
3954 from the actual code, rather than symbol table info) - though
3955 the idea is Alessandro's. I feel my code is a little cleaner
3956 here, particularly in being a little more flexible, such as being
3957 able to handle gcc-produced code (which it now can).
3958 It also doesn't do frame caching (which is not useful
3959 more recent gdb versions).
3960 I also used my code for push_/pop_dummy, more or less.
3961 I tried to incorporate AF's code for testing sigtramp
3962 while backtracing; I probably got it wrong.
3963 Added mips_print_register, which tries to scrunch as much
3964 information as possible on a screen...
3965 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3966 under mips-pinsn.c), I don't see anything mips-specific here,
3967 and I don't see it being all that useful anyway.
3970 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3971 Use more register names (rather than hard-cases numbers).
3973 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3975 * Hack up 3.90.11 changes:
3977 * Makefile.dist (depend): parameterize $(GCC).
3978 Add solib.c and solib.o.
3979 (readline): Fix vpath for both absolute or relative SRCDIR.
3981 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3982 Also, let the part I didn't understand at least compile so
3983 I can test the rest. FIXME.
3985 * dbxread.c: Fix thinko using strcmp.
3986 (init_psymbol_list): declare static.
3987 (partial_symbol_file_open): Comment cleanups better, avoid
3988 cleaning up the string table since the caller will do that.
3989 Move the stat for mod time into symbol_file_command, temporarily.
3990 (There should be a mod time for each symbol file, eventually,
3991 to control its rereading. FIXME.)
3993 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3994 SunOS, which gives error for shared libs otherwise. (From
3995 Schaefer, probably FIXME needs work for portability.)
3997 * solib.c: Move #include "param.h" to work.
3998 Lowercase all the Uppercase Letters In the Messages.
3999 (find_solib): Clean up inferior_so_name for debug printouts.
4000 Allow no argument, to mean all shared libraries.
4002 * symmisc.c: include param.h to get CLEAR_SOLIB.
4004 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
4006 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
4007 to 3.90.11. ChangeLog entries below are from this.
4009 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4013 * Makefile.dist (HFILES): Add tm-sunos.h.
4015 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4019 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
4021 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
4023 * sparc-opcode.h Added single-operand version of rett.
4025 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4027 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
4028 Put parens around gcc_p in expansion.
4030 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4032 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
4034 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4036 * Changes for Sun shared libraries:
4037 blockframe.c (find_pc_partial_function): If a non-text symbol
4038 is found, set *address = pc - FUNCTION_START_OFFSET.
4039 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
4040 Disable breakpoints instead of giving an error.
4041 source.c (select_source_symtab): Initialize cs_pst.
4042 symmisc.c: Call CLEAR_SOLIB if defined.
4043 symtab.h: Make text{low,high} CORE_ADDR not int.
4044 (psymtab): New field addr.
4046 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
4047 (record_misc_function): Give correct type for N_DATA symbols.
4048 (condense_misc_bunches): do "misc_function_count = j" regardless
4050 Take code which is shared between symbol_file_command and
4051 add_file_command and put it into partial_symbol_file_{open,read}.
4052 Split add_file_command into add_file_command and add_file.
4053 Make psymtab_to_symtab read in the string table if the file
4055 Two new parameters to read_dbx_symtab and start_psymtab.
4056 tm-sunos.h: New file.
4058 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4060 * infcmd.c: Change cont_command to continue_command and "cont"
4063 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4065 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
4067 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
4069 * values.c (USE_STRUCT_CONVENTION): Check for structures of
4070 size 1,2,4,8 rather than size < 8.
4072 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
4073 as necessary, not just once.
4075 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
4077 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4079 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
4081 * tm-news.h: Add CALL_DUMMY_*.
4083 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
4085 * config.gdb: In list_host, list_target, use ${i}, not $i.
4087 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4089 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
4091 * sparc-opcode.h: Change all store floating-point state register
4092 instructions to have the right match & lose fields.
4094 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4096 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
4098 config.gdb: If srcdir != ., create readline directory and
4099 copy a makefile into it.
4101 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
4102 consistency with POSIX.
4104 * breakpoint.c (bpstat_stop_status): Disable watchpoint
4105 when we exit its exp_valid_block.
4107 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
4109 * Makefile.dist: Bump version to 3.91.3.
4111 * Clean up handling of breakpoint commands (somewhat).
4112 Prompted by Tiemann bug report "cont 10" doesn't work any more.
4114 inferior.h: Add breakpoint_proceeded to inferior status struct
4115 and globals; save it and restore it.
4116 (clear_breakpoint_commands): Cleanup, remove old #define.
4118 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
4119 (save_inferior_status, restore_inferior_status): handle it also.
4120 (proceed): Remove earlier code that set breakpoint_proceeded.
4121 It is now set only in clear_proceed_status.
4122 (clear_proceed_status): Cleanup, use bpstat_clear rather
4123 than clear_breakpoint_commands. No callers need the stop_bpstat
4124 between clear_proceed_status and proceed.
4126 infcmd.c: Add breakpoint_proceeded definition and comment.
4127 (cont_command, jump_command, signal_command): Move call to
4128 clear_proceed_status right next to call to proceed.
4130 breakpoint.c (bpstat_do_actions): Avoid clobbering our
4131 caller's argument while running down the chain of breakpoints.
4132 Use new variable "breakpoint_proceeded" to determine when
4133 a command that it executes moves the inferior past the
4135 (bpstat_clear): Handle NULL argument.
4136 (bpstat_clear_actions): Avoid useless call to
4137 breakpoint_auto_delete.
4138 (delete_breakpoint): Clean up bpstat's that are pointing to
4139 the deleted breakpoint from the stop_bpstat chain.
4140 (breakpoint_auto_delete): Simplify.
4142 * Clean up handling of EOF, error on stdin, etc. This was
4143 prompted by a network problem that caused gdb to go into an
4144 infinite loop filling up its malloc'd memory.
4146 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
4147 not clear_breakpoints_commands, which is now gone.
4148 (main): If command_loop returns (e.g. from EOF on stdin), do
4149 a quit_command (looping back to command_loop if quit_command
4150 doesn't really quit).
4151 (command_loop): check result from command_line_input and
4152 exit if it returns NULL, rather than passing the NULL to
4154 (gdb_readline): Free malloc'd result space before returning
4157 * utils.c (query): Handle C-d to mean "yes", just as if the
4158 input was not a terminal. Also avoid infinite loop if EOF
4159 occurs in mid-input-line before newline. This allows
4160 query to be used at EOF on stdin with reasonable results.
4162 * infrun.c (proceed): Set breakpoint_proceeded.
4164 * values.c (value_as_long): Avoid infinite recursion for enums.
4165 (_initialize_values): Fix typo in help msg (kingdon).
4167 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
4168 RL_LIB for linking. This allows -lreadline for linking
4169 and nothing for dependencies, once readline is a real library.
4171 * config.gdb: Jim Kingdon: give useful error message if the
4172 host or target type is not recognized.
4174 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
4175 it just defines it. Dumb, but deal with it.
4177 * Jim Kingdon suggests:
4178 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
4180 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
4182 * Makefile.dist (VERSION): Bump version # to 3.91.2.
4184 * Clean up Bothner's changes.
4186 * blockframe.c (clear_pc_function_cache): New function.
4187 * blockframe.c: remake cache_pc_function_* static.
4188 * dbxread.c (symbol_file_command): remove references to
4189 cache_pc_function_* variables.
4190 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
4191 * printcmd.c: Avoid kludging a global variable (addressprint)
4192 to avoid printing the address of a string twice. Instead,
4193 pass the format letter 's' down low enough that it can be seen
4194 to avoid this problem.
4195 (print_formatted): Pass format arg to value_print.
4196 (restore_addressprint): Remove function.
4197 (do_examine): Avoid hacking addressprint, cleanups and such.
4198 (print_frame_args): Add a comment to a Bothner change.
4199 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
4200 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
4201 to wipe out the values cached in blockframe.c.
4202 * symtab.c (find_method): Add comment saying how big you must
4203 allocate to be "big enough". Per being terse again.
4204 * valprint.c (val_print): Handle format letter "s" to print
4205 strings without addresses. Add comment to vtbl printing code
4206 which casts with wild abandon. Rearrange reference-printing
4208 @0xaddr: value (print w/addressprint)
4209 value (print w/~addressprint)
4210 @0xaddr (parameter lists w/addressprint)
4211 or nothing (parameter lists w/o addressprint)
4213 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
4215 * Merge more changes from Per Bothner:
4217 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
4218 annoying) that I tried to improve it. Here are my suggestions.
4220 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
4223 Do automatic de-reference when taking the address of a reference.
4225 Don't deref_ref when printing parameter lists.
4227 More attempts at treating refernences properly.
4229 In val_print, if deref_ref==0, don't print dangling " = ".
4231 Add COERCE_REF macro, which de-references an REF.
4233 * Merge changes from Per Bothner:
4235 * Fixed (Sony news)-specific configuration problems.
4236 * Fixed other problems with using vanilla pcc and libc (enum problems;
4237 assumption that vsprintf exists).
4238 * Some major speed-ups (finc_pc_partial_function now caches a match;
4239 parsing avoids duplicate symbol_lookup calls).
4240 * Changed handling of baseclasses (no longer use baseclasses field
4241 of struct type, use the first n_baseclasses fields instead).
4242 * Various minor changes/fixes, most C++-related.
4245 Cache the most previous match from find_pc_partial_function.
4246 (Save both low and high ends of matching function's pc range.)
4247 This speeds up the loop of infrun.c:wait_for_inferior quite
4248 a bit, and makes step/next commands much zippier.
4250 Added an enum->int cast (otherwise, some compilers barf).
4252 No longer set baseclass offset to 0, since multiple
4253 inheritance now mostly works.
4254 Added a number of casts, to shut up compiler warnings
4255 (after stabs where made enums, not ints).
4256 When discarding a symbol table (in symbol_file_command),
4257 must clear the cache introduced in blockframe.c.
4258 Don't convert $vtbl_ptr_type to vtbl any more.
4259 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
4260 Mask off sign bit emitted by g++ for virtual table offset.
4261 Set voffset to -1 (not 1) for static member functions.
4263 Changed parsing/lexing of names to avoid doing symbol lookup twice
4264 (once when lexing to determine symbol class, once for real).
4265 Now only call symbol_lookup once. Fields of 'this' win especially big.
4267 Subpress printing addr twice in the case of 'x/s addr'.
4269 lookup_basetype_type is no longer used.
4270 Add find_methods as recursive helper function to decode_line_1.
4271 This allows multiple inheritance to work.
4272 Also, once one or more matches has been found, do not look in
4273 base-classes. (Baseclass methods would be overridden, anyway.)
4275 Removed baseclasses array in struct type.
4276 Instead of using baseclasses[i], use fields[i-1].
4277 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
4278 Changed sign convention of voffset (previous was inconsistent).
4280 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4282 Used to assume existence of vsprintf. Re-written to not need it
4283 if HAVE_VPRINTF is undefined.
4285 typecmp was too pessimistic. Made it less so.
4287 Don't print space after address.
4288 If vtable points to a misc symbol (with 0 offset), print it,
4289 since that indicates the actual class of the object.
4290 Changed ype_print_derivation_info to use new inheritance
4291 scheme (without baseclasses vector).
4293 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4294 Also, changes needed because TYPE_BASECLASSES were removed.
4296 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4298 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4301 If there is no path set, and the symbols don't indicate what directory
4302 a file was compiled in, look in the current directory. But either
4303 a path or a known compilation directory will prevent this.
4306 Three independent bug fixes:
4307 * Remove the #if 0 block that breaks some stuff.
4308 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4309 adapt gdb to either SunOS 4.0.* or 4.1.
4310 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4313 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4316 (type_print) Demangle the name being printed.
4317 (type_print_base) Handle botched demangling without coredump (tiemann).
4320 (check_stub_method): Document routine.
4321 (tiemann) fix bug for no-arg functions
4322 Avoid clobbering beyond end of malloc'd storage.
4323 Terminate the argument list properly.
4325 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4327 * Changes merged by John Gilmore:
4330 In breakpoint_1, use new print_address_symbolic instead
4331 of find_pc_partial_function. (This forces use of assembler-level
4332 addresses, and avoids misleading non-mangled source-level names.)
4334 Generalize ansi argument such that -1 means skip arglist totally.
4335 Removed global variable print_ansi_qualifiers (which made
4336 code non-reentrant), in favor of extra explicit arguments
4337 to internal routines.
4339 Add new helper function print_address_symbolic.
4340 Use find_pc_misc_function instead of find_pc_partial_function
4341 (since we want assembler-level symbols here).
4343 Print unknown function as just "f (...)", not "f (...) (...)".
4344 Use new fputs_demangled explicitly.
4346 Fixed a typing violation (problem: value.h cannot be imported
4347 without renaming many variable in this file).
4348 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4349 decode_line_1: Moved forward some never-reached code.
4350 Made decode_line_2 skip function prologues correctly.
4352 fputs_filtered should not demangle by default.
4353 Add new fputs_demangled to demangle on demand..
4355 Change value_struct_elt to use value_primitive_field (using recursive
4356 utility function search_struct_field). This allows foo.bar to work
4357 for multiple inheritance (so far only for data fields).
4358 Change check_field in the same way (recursive helper function
4359 to support multiple inheritance).
4360 (Note: there are more of these problems that I haven't fixed.
4361 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4362 value_of_this: 'this' symbol name is now just "this", note "$this".
4364 Don't print static members.
4365 Avoid printing "members of <type>" if there are none.
4366 Simplified type_print_derivation_info by merging duplicate code.
4367 Remove useless blank lines in type_print_base (ptype command).
4369 Added declaration of new routine value_primitive_field.
4371 Added value_primitive_field which is generalized version of
4372 value_field that can handle multiple inheritance (non-zero offsets etc).
4373 Re-implemented value_field to call value_primitive_field.
4375 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
4377 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4378 delete the whole environment. Karl Berry reported the bug.
4379 * source.c - fix openp to avoid //'s in filenames, which
4380 trigger an Emacs bug causing it to not be able to find files
4381 when running gdb in a window.
4382 * dbxread.c - zap the #if 0 that botches the add-file code.
4383 It seems to work a lot better without all the code commented out.
4385 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
4387 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
4390 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
4392 * Makefile - added a ${CFLAGS} to a couple of entries,
4393 added remote-sa.sparc.c
4394 * added remote.sa-sparc.c, a modification of remote.c
4395 which conducts a dialog directly with the SparcStation prom.
4396 * breakpoint.c, infrun.c, sparcdep.c added
4397 remote_insert_breakpoint(), and remote_remove_breakpoint()
4398 to breakpoint.c instead of directly writing breakpoint instructions.
4399 * sparcdep.c on remote_debugging,there is no need
4400 to remove signle step breakpoint instructions.
4401 * main.c added "-epoch" flag and "int epoch_interface" to main.c
4403 * printcmd.c - epoch interface sends lisp expressions to open up
4404 epoch windows on inspection.
4405 * valprint.c - added arrayprint, and addressprint and made adding
4406 format controls easier
4407 * wait.h added a couple of undef's because we were getting
4408 complaints about WSTOPSIG and WTERMSIG begin redefined.
4411 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
4413 * symtab.c (decode_line_1): Add support for handling method stubs
4414 in the type information.
4416 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
4418 * values.c (baseclass_addr): Run loop from INDEX+1 to
4419 N_BASECLASSES; otherwise, we can still get into a loop.
4420 @@ This should be restructured to use a cleaner search strategy.
4422 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
4424 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
4425 abbreviation "Tt" for tags which have the same name as their
4428 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
4430 * symtab.c (list_symbols): add ability to set breakpoints on all
4431 the functions which match a particular regular expression.
4433 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
4435 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
4436 should print ANSI qualifiers (such as `const' and `volatile').
4437 All callers changed to call with ANSI == 1, except from
4438 `check_method_stub', which uses old-style syntax.
4440 * symseg.h (struct fn_field): Remove unneccessary `args' field.
4441 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
4443 * values.c (check_stub_method): New function.
4445 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
4447 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
4448 * valprint (type_print_base): Ditto.
4450 * symtab.c (gdb_mangle_typename): New function.
4452 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
4454 * breakpoint.c (catch_command): New function. Provides a
4455 mechanism to set breakpoints based on catch clauses.
4456 (disable_catch): Similar, but disables breakpoints on catch
4458 (delete_catch): Similar, but deleted breakpoints on catch clauses.
4460 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
4462 * blockframe.c (blockvector_for_pc): New function.
4463 * blockframe.c (block_for_pc): Changed to call
4464 `blockvector_for_pc' and get the block itself.
4466 * stack.c (catch_info): New function. Prints info about
4467 exceptions which can be caught in the current frame.
4468 * stack.c (print_frame_label_vars): New function. Similar to
4469 `print_frame_local_vars'.
4470 * stack.c (print_block_frame_labels): Prints out labels that are
4471 defined in this frame. These labels are exceptions that can be
4474 * dbxread.c: Updated to handle N_CATCH symtab types.
4476 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
4478 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
4479 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
4480 when printing the type.
4482 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
4484 * valprint.c (val_print): Use `baseclass_addr' to access the
4485 baseclasses pointed to via the derived class object at VALADDR.
4487 * values.c (baseclass_addr): New function. Casts derived pointers
4488 to baseclass pointers taking virtual baseclasses and multiple
4489 inheritance into account.
4491 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4495 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4497 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
4498 exp_valid_block field correctly.
4500 * infrun.c (wait_for_inferior): When checking "don't even think
4501 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
