1 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
3 * doc/refcard.tex: permuted Essential Commands sec
5 * doc/gdb.texinfo: new C++ chapter; revised installation appendix.
7 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
9 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
10 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
11 breakpoint.c, main.c: lint.
13 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
15 Install new configuration scheme for GDB and friends.
17 * config.sub: Translate ordinary names to three-part names.
18 * configure: Use three-part names internally.
19 * configure.in: Translate three-part names to filenames.
21 * README, WHATS.NEW: Update for gdb-4.0.
22 * Makefile.in: Roll VERSION to 3.99.
24 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
26 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
27 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
28 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
29 to single structures rather than arrays; when passing
30 their address, use &. This avoids trouble with bdead compilers.
31 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
32 instead. This avoids portability headaches.
33 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
35 * source.c (open_source_file): Avoid ANSI const bdeath by
36 skipping declaration and then casting result value.
37 * tm-hp300bsd.h: Clarify comment.
38 * utils.c (strstr): Result is const char *; ANSI bdeath.
39 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
40 since system include file defines it differently from "defs.h",
41 though the two are equivalent for our purposes.
42 * tconfig/hp300bsd: Add m68k-tdep.o.
44 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
46 * tconfig/sun*4: Remove warnings about system assembler.
48 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
50 * mcheck.c: Avoid warning about undeclared abort fn.
51 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
52 it causes recursive calls to error() when used in cleanups.
53 To do so requires that we make it a function, so we do.
54 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
55 * utils.c (do_cleanups): Remove the current cleanup from the
56 chain *before* calling it, in case error() is called from it.
57 The result won't be pretty, but won't be an infinite loop either.
59 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
61 * dbxread.c (read_struct_type): Grok anon structs for C++.
62 (vb_name, vptr_name): Null terminate these strings.
64 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
66 Minor bug fixes from BSD Net2 gdb:
68 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
69 returns 0, there is no previous frame.
70 * breakpoint.c (commands_command): If !from_tty, don't call
71 input_from_terminal_p().
72 * dbxread.c (record_misc_function): Speed up slightly.
73 (compare_psymbols): Ditto.
74 * infcmd.c (do_registers_info): Take a second argument to
75 determine whether to print float registers. "info registers"
76 does not do so anymore. "info all-registers" does, now.
77 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
79 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
80 * inflow.c (initialize_inflow): Set tflags_ours correctly.
84 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
85 executing_breakpoint_commands if we are interrupted by error.
86 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
87 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
88 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
89 catch_errors() so we can setup the frame regardless of whether
91 * ieee-float.c (double_to_ieee_extended): Get exponent from
92 right place in little-endian systems. From John Carey.
94 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
96 * main.c: Remove unused terminating_signals and catch_termination().
97 (long_options): Terminate with a zero element.
98 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
99 (gdb_readline): Make call-compatible with readline.
100 (init_signals): Improve comments re vfork vs. signal.
102 * utils.c (prompt_for_continue): Use new gdb_readline().
103 If we prompt for continuation, we don't let CR repeat the previous
104 command, once we get back to a prompt. It's too easy to keep
105 hitting CR, expecting "--more--" prompts, and have some long
106 command start repeating on you.
108 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
110 * blockframe.c (frameless_look_for_prologue): Speed up by
111 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
112 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
113 Define two variants, one faster.
114 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
115 and return zero, rather than giving an error.
116 (setup_arbitrary_frame): Initialize the PC in the new frame.
117 (skip_prologue): Add a second arg saying whether we're just
118 checking for a frameless function or not.
120 * core.c (core_open, core_close, core_xfer_memory): Move
121 section table pointers and bfd* into the target_ops.
122 (core_open): Allow errors in shared lib reading, etc.
123 (core_files_info): Describe shared library sections.
125 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
126 exec_files_info, set_section_command): Move section table
127 pointers and bfd* into the target_ops.
128 (add_to_section_table): Add BFD to section table.
130 * target.c (target_xfer_memory, target_info): Pass target to
131 xfer_memory and target_info functions.
134 * gdbcore.h: Move struct section_table.
135 * target.h: New home of struct section_table.
137 * solib.c (solib_add): New argument is the target_ops whose
138 section list is to be added to, if any. Reallocate the
139 sections in that target to add any that come from shared libs.
140 (throughout) so_sections renamed to sections.
141 (solib_xfer_memory): Deleted.
142 * tm-sunos.h (SOLIB_ADD): Add target argument.
143 (SOLIB_XFER_MEMORY): Delete.
145 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
146 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
147 from target_ops. It's the same on all targets. Add two section
148 pointers to target_ops.
150 * stack.c (find_relative_frame): Dump ancient algorithm for
151 "down", just use handy "next" pointers.
152 (frame_command): Don't error if there is no stack; let user
155 * inflow.c (new_tty_prefork, new_tty): New prefork routine
156 modifies static state in the parent process; new_tty itself
157 runs in the child and modifies the child's file descriptors
158 to match the saved static state.
159 * infrun.c (child_create_inferior): Call new_tty_prefork,
162 * infptrace.c (child_xfer_memory): Add ignored target arg.
163 * remote-eb.c (eb_xfer_inferior_memory): ''
164 * remote-nindy.c (nindy_xfer_inferior_memory): ''
165 * remote-vx.c (vx_xfer_memory): ''
166 * remote.c (remote_xfer_memory): ''. Rename from
167 remote_xfer_inferior_memory.
169 * main.c (main): Only try to attach "corefile" argument if
170 it starts with a digit.
172 * symfile.c (symbol_reloading): New "set/show" variable.
173 (symbol_file_add): Shorten message about symbol reading.
174 (add_symbol_file_command): Merge with add_syms_addr_command,
175 since this should work on all targets now.
176 (stop_whining): Default to zero, to shut up complaints
177 about bad symbol tables on many systems.
178 (free_named_symtabs): Just exit unless symbol_reloading.
180 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
181 and add comment explaining shared library screw.
183 * source.c: #if defined => #ifdef.
185 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
187 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
189 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
191 * doc/rdl-apps.texinfo: provide default readline-appendix finder
192 (doc/Makefile knows how to make one for local config)
194 * Makefile.in: use doc/Makefile for doc targets
196 * doc/Makefile: GDB documentation now has its own Makefile
197 doc/refcard.tex: renamed from "gdbrc.tex"
198 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
199 doc/gdbint.texinfo: add markup in "Cleanups" chapter
202 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
204 * values.c (baseclass_addr): When reading target memory, use the
205 length of the basetype, not the upper type. We've only malloc'd
206 enough space for the basetype, leading to errors in free().
208 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
209 ends up as a function specially, since we know the actual type of
210 the pointed-to address. This (somewhat) fixes display of
211 expressions that include misc_function_vector names. Try `cond 1
212 !strcmp("a","b")' then `i b'.
214 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
215 The child can be proceeded from inside wait_for_inferior in
216 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
217 getting skipped in that case.
219 * expprint.c (print_subexp): Use filtered output, since the
220 subroutines we call use it, otherwise the output is horribly
221 mangled, since output of wrappable stuff comes out late.
223 * Makefile.in: Bump VERSION to 3.98.1
225 * infrun.c (child_create_process): Use execlp to find the
226 shell to exec our target program. This requires some fiddling
227 with `environ' since there is no execlpe().
229 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
231 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
232 Minor rearrangement of refcard permits two new make targets--
233 gdbrc.dvi DVI output for refcard, using CM fonts
234 gdbrc.ps PostScript refcard, using PS fonts
236 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
240 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
241 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
243 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
245 * doc/gdb.texinfo: last changes for release.
246 Minor typo and formatting fixes; incorporated most fixes remaining from
247 filed mail commenting on earlier drafts.
249 Added warnings: pipes don't work in run command;
250 conditions are converse of assertions;
251 step over fn without debug info goes to next fn;
252 vars may have "wrong" values near fn entrance, exit
254 Added example from Kingston on printing repeated nonadjacent values
256 Added explicit mention that in Emacs gdb mode C-c and C-z are like
257 shell mode for signals
259 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
260 doesn't sound so much like its parent "Stopping and Continuing"; also
261 moved entries on continue to top of section, so they don't get lost.
263 Improved installation directions in appendix, added manual formatting
266 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
268 * configure.in: Remove xm.h and tm.h even if we aren't linking
269 new ones, so "./configure sun4; ./configure none" does the right
270 thing. Assume that alldeps.mak and depend are already built in
271 srcdir, and avoid running "make" (particularly "make depend",
272 which involves "gcc") from inside configure. Build Makefile
273 directly rather than building Makefile.conf first.
274 * configure: Regenerate with above changes.
275 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
276 to 3.98. Revise gdb.tar.Z procedure to produce a file
277 called gdb-$(VERSION).tar.Z but which unpacks into a
278 directory called "gdb". Move non-source files out of
279 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
280 (depend): Don't try to do "gcc expread.y".
281 (expread.o): Update dependencies by hand.
283 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
286 Fixed a variety of small typos that prevented info from formatting
287 cleanly; altered too-long heading for GPL Appendix, as discussed
288 w/RMS; Changed date on cover to July 91.
290 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
293 (1) Applied some fixes due to comments from Larry Breed (easier ones
295 (2) Eliminated use of @footnote---had my doubts about it anyways, and
296 it's broken in latest texinfo
297 (3) Introduced *some* use of [] for optional arguments, where
298 explanation is not simpler by listing cmd w arg and cmd w/out arg
299 separately. Still not using @deffn.
300 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
301 couple of headings are too long. Need patches to texinfo or revision
304 * Partial update to README (which still needs work for this
305 release!): (1) use of configure corrected for new script,
306 (2) "make gdb.dvi" and "make gdb.info" mentioned.
308 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
310 * symtab.c (lookup_symbol): Don't complain right off about
311 no debug symbols; use the misc function vector first.
312 (list_symbols): Use misc function vector to find symbols
313 that don't have debug info, and print them.
314 (find_pc_symtab): Temporarily avoid fatal() when psymtab
315 PC range doesn't match symtab PC range, as it does on the
316 MIPS because our symtab reading isn't perfect.
318 * dbxread.c (dbx_symfile_read): Make warning about
319 "no debug symbols" slightly nicer.
321 * source.c (select_source_symtab): If "main" symbol exists,
322 but decode_line_spec can't find line info, don't just return
323 a zero; try other source symtabs or give an error.
325 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
326 their low addresses first, then rip through fixing high addrs.
328 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
330 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
332 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
334 * Minor, mostly mechanical, cleanup of doc subdir for clean
335 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
336 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
338 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
340 Mostly MIPS and general symbol-reading fixups.
342 * doc/gdbint.texinfo: Add documentation on symbol-reading
345 * mipsread.c: Remove kludges around #include "ecoff.h".
346 Remove redefinitions of a_magic, etc, no longer used.
347 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
348 Fix global overview comments to match symfile.c protocol.
349 (mipscoff_new_init): Eliminate cur_hdr if we have one.
350 (mipscoff_symfile_read): Eliminate unused code. Avoid
351 sorting all the symtabs, when all we have read here is psymtabs.
352 The symtabs are sorted as they are created anyway. Tell
353 condense_misc_bunches whether we're mainline.
354 (psymtab_to_symtab_1): Pass filename when recursing, to make
355 stack trace more informative.
356 (parse_partial_symbols): Assume cur_hdr as argument.
357 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
358 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
359 the TYPE_NAME of char *, since that's done in symfile.c.
360 (free_numargs, parse_symbol, add_symbol, add_block,
361 shrink_linetable): Declare these fns void.
362 (upgrade_type): Convert tree of if's to switch. Clean up
363 bogus "off == 0" handling with a complaint. Avoid setting
364 field bitpos and bitsize of array with lower and upper bounds.
365 Check specified bitsize of elements against their actual type's
366 bitsize, and complain if different. Complain about unknown
368 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
369 (psymtab_to_symtab_1): Print names of subsidiary files that
370 are being read in. FIXME, we read far too many files. This code
371 is not the problem, the problem is in parse_fdr where the psymtabs
373 (cross_ref): Result should indicate that we used one aux entry
374 normally, or two if we encountered a "next" entry. This used
375 to leave the caller pointing at the wrong aux entry.
376 (add_symbol): If overflowed cur_block, reallocate it larger,
377 chase all pointers to it, and complain(), rather than clobber memory.
378 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
379 (new_field): Only allocate one field initially, not two.
380 Pull ++ out of macro argument. Simplify.
381 (_initialize_mipsread): Avoid initialization of importd
382 global_psymbols and static_psymbols.
384 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
385 to properly set pst->symtab; avoid searching for it.
386 (symfile_fns): Improve comments, add a FIXME.
387 * dbxread.c: Update comments to reflect symfile protocol.
388 (read_ofile_symtab, end_symtab): Return the symtab.
389 (psymtab_to_symtab_1): Set pst->symtab.
391 * coffread.c (coff_symfile_read): tell condense_misc_bunches
392 whether we're mainline.
394 * symfile.h (sym_fns): Remove unused sym_discard member.
395 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
397 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
398 the environment variable is not.
399 * infcmd.c (finish_command): Use filtered printfs.
400 * cplus-dem.c: Add struct tags to a few unnamed structs.
401 * valops.c (value_coerce_array): Improve comments.
402 * valprint.c (type_print_varspec_suffix): Print array size only
403 if greater than zero.
404 * m88k-tdep.c: Shift some lines left by one space, that had
405 apparently been trashed at some point.
406 * TODO: More things to do, a few got done.
408 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
410 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
411 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
413 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
414 * expread.y, findvar.c, symmisc.c: Ditto.
415 * printcmd.c (address_info): Update printed forms of LOC_
416 symbols. Elim LOC_EXTERNAL.
417 (print_frame_args): Keep track of param stack offsets before
418 re-looking up to find the local register param is kept in.
420 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
421 Further integration of mipsread into gdb. Eliminate unused
422 routines, duplicate declarations. Handle static symbols in
423 psymtabs as well as external symbols. When reading symtabs,
424 insert symbols into the correct block (global, static, or a local
426 (read_mips_symtab, parse_partial_symbols): Don't pass useless
428 (mipscoff_symfile_read): Don't call select_source_symtab.
429 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
430 rather than SYMBOL_VALUE.
431 (parse_external): Comment clobbering of top_stack.
432 (parse_partial_symbols): Update comments. Allocate and parse
433 static symbols as well as external symbols. FIXME, enum values
434 are not handled in this pass, but should be. Inline new_psymbol.
435 Use SYMBOL_VALUE_ADDRESS.
436 (psymtab_to_symtab_1): Read symbols into global static block
437 by default (until enter some function's local block context).
438 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
439 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
441 * source.c (select_source_symtab): Select a source symtab
442 from either the symtabs or, failing that, the psymtabs.
443 (list_command): Update error message.
444 (forward_search_command, reverse_search_command): Use getc, not
445 fgetc, for speed. FIXME, add comment about buffers that die if
446 overrun by long line.
448 * values.c (unpack_field_as_long, modify_field): Avoid shifting
449 by an entire word, which is not portable, if we have a 32-bit
450 field. (Code in dbxread.c already turns such bitfields, if
451 aligned, into ordinary ints, but fixing this will help for other
452 symbol formats and for future changes.)
453 * core.c (core_open): Handle ANSI const brain death.
454 * utils.c (vprintf): Fix varargs typo.
456 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
458 * findvar.c (find_var_value): Handle &function better.
459 * TODO: Document work needed on &fn and &array.
460 * printcmd.c (print_address_symbolic): New arg is the prefix
461 to print if a name is printed.
462 (print_address_demangle): Honor "set print address" now.
463 Use new arg above to improve spacing of output.
464 * valprint.c (val_print): When printing function pointers,
465 print symbolic form too.
466 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
468 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
470 * core.c (memory_error): Reword error msg to mislead less.
472 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
474 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
475 parse_partial_symbols): Use newer BFD internals (external_filehdr
476 and external_aouthdr), byte-swap the fields that we care about
477 before using them, and make the file header data local to
478 read_the_mips_symtab rather than global.
480 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
482 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
483 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
485 * main.c (command_line_input): Flush stdout and stderr
486 before every call to readline. This reportedly fixes a bug
487 that comes up in Sys V running emacs-gdb and/or xxgdb,
488 when stdin/out are pipes or sockets.
490 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
492 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
493 Avoid declaring Makefile dependencies, because GNU Make stupidly
494 tries to update it if we do.
496 * coffread.c: Revise for minor changes to bfd internal coff
499 * configure: If -template= is given a relative path, make it
500 absolute before recurring in subdirectories.
502 * configure, configure.in, Makefile.in: Install "configure" script
503 as replacement for config.gdb.
504 * config.gdb, Makefile.dist, Makefile.sdir: Remove
505 * README: Update for configure, mostly. FIXME.
507 * Add dec3100 as equivalent to littlemips. Indicate in all host &
508 target config files that they are for the host. When the lines
509 get copied into the Makefile, this makes it more obvious what's
512 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
514 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
515 tabs, which end up in the disassembler output inadvertently.
517 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
519 Make it compile cleanly in an ANSI GCC2 environment.
521 * blockframe.c: <stdio.h>
522 * cplus-dem.c: free takes a void *, ifdef __STDC__
523 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
525 * defs.h (alloca): Avoid doing anything if alloca already def'd.
526 * stddef.h, stdlib.h: Remove these files.
527 * symtab.c: Avoid declaring qsort, close.
528 * symfile.c: Avoid declaring close.
529 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
530 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
532 Assorted other changes.
533 * dbxread.c: include "libaout.h", not "liba.out.h".
534 * printcmd.c (print_frame_args): Set recurse properly for
535 indentation of struct and array parameters.
536 * valops.c (value_cast): Allow cast to void.
537 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
538 single_step() in a target-independent fashion.
539 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
540 set up to be ready to continue. This makes us target independent.
541 * infptrace.c (child_resume): Remove call to single_step; now
542 can single step a SPARC target of any kind.
544 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
546 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
547 docn into separate sections---basically chapters, plus two loose
548 pieces that can be configured to go in different places. This
549 allows GNU m4 to preprocess the manual without coredumping.
551 * Makefile.dist: tell TeX where to find texinfo.
553 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
555 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
556 the new target "rdl-apps.texinfo" which captures the Makefile
557 variable that records where to find the Readline libraries.
559 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
561 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".

564 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
566 * README: Update for release 3.95.
567 * config.gdb: Don't create readline dir in subdir builds.
568 * main.c: Include with "..." form for non-system include files,
569 so "gcc -MM" for "make depend" works.
570 Include readline files with "...h" rather than <readline/...h>.
571 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
573 * coffread.c: Undo minor damage done by Rich Pixley. Use
574 different internal and external representations of COFF
575 data structures. Use new BFD routines for swapping them in and
577 * symfile.c (free_named_symtabs): Avoid freeing file names that
578 are null or empty. Old i960 tools seem to produce files that
579 claim to have empty names, causing each successive file read
580 to blow away the previous one.
581 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
582 Move deferred_stores to top of file, but don't separate its
583 #define's from its variable. Add commentary.
584 * Makefile.dist: Fix Rich damage; undo "configure" changes in
585 favor of keeping the (working) config.gdb. Move readline

590 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
592 * infptrace.c (fetch_registers): no result, since now void.
593 * tconfig/news: target depends on m68k-tdep too.
595 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
597 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
600 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
601 applied various small fixes due to or inspired by RMS comments
603 * doc/gdb.texinfo: finished using all RMS comments, save those for
604 appendices on readline and cmd history (which are in other source
607 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
609 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
610 chapter 9; (2) documented 'break' command's menu mode for
611 overloaded names, in response to hgs problem report C++ p-31
613 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
615 * doc/gdb.texinfo: (1) better introductory example; (2) more
616 consistent use of @code, @samp, @file, @kbd throughout; small
617 cleanups to first three nodes; (3) new "Contributors" node;
618 (4) Appendix, Renamed Commands; (5) divert specialized startup
619 instructions to "Targets" chapter for generic manuals, while
620 leaving them up front for manuals specific to specialized
621 environments; (6) apply fixes from RMS comments through chapter 4.
623 * pretex.m4: modify explanatory text slightly (and redefine
624 "regexp") to keep GNU m4 from complaining. (It still crashes
625 later, but one step at a time...)
627 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
629 * readline/readline.c (update_line): Avoid dereferencing a pointer
630 before comparing it to its bounds. Saber caught this.
631 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
632 and only set PC if tgetstr returned non-null. Saber caught this.
634 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
636 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
637 stuff for config manual) here where it counts; updated
638 to use new subdir structure (gdb/doc/).
640 * Makefile: generated from above via
644 * gdbint.texinfo: added instructions on generating gdb.info* files
645 locally for release. These are ordinary info
646 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
647 Makefile)---but due to use of texinfo 2, can't count on makeinfo
648 to generate these, so we distribute them already formatted.
650 * gdb.texinfo: included full Info node and menu crud (as generated
651 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
653 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
654 put in comments-for-future gdb.info target (one day makeinfo will
657 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
659 * gdb.texinfo: Updated to include new or old undocumented
660 commands, at least the following (perhaps some others I forgot to
661 record): info f, info float, info path, info program, info s, info
662 set, info source, info terminal, info types, info user, set/show
664 Also covered all recent GDB command renames for v4.
666 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
668 * mipsread.c: Rather than keeping count of how many symtabs
669 and psymtabs we have, for sorting purposes, count them when
670 we need to sort. This fixes bug in rereading of symbol tables.
672 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
674 * infcmd.c: renamed "info path" to "show paths"

689 symtab.h, target.c, target.h: Lint.
690 * core.c: setup and select frame after reading shared libs,
691 else reading shared libs will clobber them. Lint.
692 * utils.c (error): Force out any buffered wrap text.
694 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
696 * remote.c: Remove decls of memory_insert_breakpoint
697 and memory_remove_breakpoint, no longer used. (Suggestion of
700 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
701 to make it easier to interface to "configure"'d libraries.
703 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
705 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
706 aliases for set/show print.

1218 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
1219 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.

1249 command is add-symbols.
1250 * target.c (dummy_target): Permit add_syms_addr_command.
1252 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1254 Permit symbols to be superseded when new symbol files have
1255 been read in, particularly for VxWorks.
1257 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
1258 to the main file, as well as to include files. Also, put global
1259 functions into the global psymtab, to make "i fun" work.
1260 (end_psymtab): Free named symtabs and psymtabs for a file, once a
1261 new psymtab for it has been read.
1262 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
1263 a file, once a new symtab has been read for it.
1264 * mipsread.c: FIXME. We need to do the same for MIPS, but it
1265 looks harder to determine the top-level block before it's been
1266 queued to the psymtab list.
1268 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
1269 If we have wiped out any old symbol tables, clean up at end of
1271 (symbol_file_command): Don't reference symfile_fns if it's zero.
1273 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
1274 defines for the blocks of a blockvector that contain global and
1275 file-static symbols and the first of the smaller scope contours.
1276 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
1277 decode_line_1, make_symbol_completion_list): Use the above.
1278 * coffread.c (end_symtab, patch_opaque_types): Ditto.
1279 * dbxread.c (end_symtab): Ditto.
1280 * expread.y (block): Ditto.
1281 * mipsread.c (throughout): Ditto.
1282 * symmisc.c (free_named_symtabs): Ditto.
1284 * symtab.c (list_symbols): Process the first symbol of the
1285 static psymbols list.
1286 (types_info): Restore this function from its untimely #if 0.
1287 It's not perfect, but it is better than nothing.
1288 (_initialize_symtab): Restore "info types".
1290 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1292 * m68k-stub.c: Remote stub for 680x0's, created from
1293 rem-m68k.shar (which is removed).
1294 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
1295 Remove RCS log stuff now that we use CVS and it blows our diffs.
1297 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1299 * symmisc.c (free_named_symtab): Make it work, in its current
1300 kludgy fashion. Change result to indicate if we blew away bkpts.
1301 * dbxread.c (end_symtab): Accumulate result from
1302 free_named_symtab and print warning if we blew user's state.
1303 * symfile.h: free_named_symtab now returns an int.
1305 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1307 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
1308 is the first symbol read, even if not mainline.
1309 (dbx_psymtab_to_symtab): symfile might be zero, cope.
1310 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1311 (set_section_command): New command ("section xxx yyy" -- should
1312 be renamed to "set section xxx yyy" FIXME) which sets the
1313 base address of a section of the exec file, overriding the
1314 virtual address that BFD reports.
1316 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1318 * exec.c: Add add_syms_addr_command to exec_ops, so you can
1319 load symbols at any address while examining an exec file.
1321 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1323 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1324 for printing the float info is host-dependent, not
1325 target-dependent. FIXME.
1326 * i386-pinsn.c: Move #includes to top, remove useless ones.
1327 * i386-tdep.c: Don't bother including <.../reg.h> since we
1328 don't use it (and it doesn't exist on host systems).
1330 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1331 Convert negative numbers properly.
1332 (ieee_test): Make numbers really random; fix format arg.
1334 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1335 * core.c (core_detach): Unpush core_ops, which might not be on
1336 top. We used to just pop the top, which broke things. Don't
1337 need dont_repeat() any more.
1338 (core_file_command): Psst! Don't repeat it.
1339 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1340 * expprint.c (print_subexp): Avoid switch fallthru on
1341 BINOP_ASSIGN_MODIFY, so we can print += and such.
1342 * frame.h: Fix typo.
1343 * inflow.c (kill_command): After killing inferior, print our
1344 current frame in the core file, if we have one.
1345 (generic_mourn_inferior): When inferior dies, either select
1346 the current frame (in the new target, e.g. core file), or
1347 set both the current and selected frames to NULL.
1349 Changes from Peter Schauer.
1351 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1353 * Make all file names fit in 14 characters (sigh and damn!):
1354 mv hp300hpux-xdep.c hp300ux-xdep.c
1355 mv symmetry-xdep.c symm-xdep.c
1356 mv symmetry-tdep.c symm-tdep.c
1357 mv convex-opcode.h convx-opcode.h
1358 mv tm-vxworks960.h tm-vx960.h
1359 mv tm-vxworks68.h tm-vx68.h
1360 mv Makefile.srcdir Makefile.sdir
1361 mv gdb-int.texinfo gdbint.texinfo
1362 mv remote-sa.m68k.shar rem-m68k.shar
1363 mv remote-multi.shar rem-multi.shar
1364 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1365 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1366 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1369 * command.c (user_info_1, user_info): New command for listing
1370 the user-defined commands.
1372 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1374 * dbxread.c (really_free_pendings): Clear file_symbols
1375 and global_symbols after freeing them; otherwise, running
1376 this function twice (if it appears twice on the cleanup
1377 chain), we try to free things twice.
1379 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1380 based on text_addr (the address of text in core), not on addr (the
1381 offset between text in the .o file and in core). This change
1382 is from Peter Schauer.
1384 * main.c: Define ALL_CLEANUPS as a cast of zero.
1385 (return_to_top_level): Use it.
1386 (main): Do all cleanups after each command run as part
1387 of the gdb startup sequence. Also do all cleanups before
1388 entering the command loop, and every time we exit the command
1389 loop and reenter. Before, the cleanups from the startup sequence
1390 were being left undone until the first error!
1391 (command_loop): Rename do_nothing cleanup to command_loop_marker
1392 so we can see it easily when examining the cleanup chain.
1393 (init_signals): Add another do_nothing for signal handling.
1394 (quit_command): Only try to kill target if it has execution.
1395 Problems in the target stack got us into a state where
1396 inferior_pid was nonzero but none of the targets had execution.
1397 In this state you couldn't exit gdb.
1399 * dbxread.c: Two changes from Peter Schauer.
1400 (echo_command): Fflush output after an echo command.
1401 (show_history): Pass all args to cmd_show_list.
1403 * utils.c (init_malloc): Call mtrace to turn on tracing
1404 if the environment variable MALLOC_TRACE is set to a file name.
1405 * mtrace.c: Add source file which provides a log of every malloc,
1406 free, and realloc to a trace file.
1407 * mtrace.awk: Add source file which analyzes the trace file.
1408 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1409 (VERSION): Roll to 3.94.3.
1411 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1412 (check_duplicates): Don't bother with watchpoints.
1413 (set_raw_breakpoint): Comment about danger of this routine.
1414 (watch_command): Parse and eval all args before calling
1417 * solib.c (find_solib): Avoid error in referencing memory to
1418 see if any more shared libraries have been added. This is
1419 particularly useful if the target has terminated. Bug reported
1422 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1423 in bringing up 3.94.2 on the Sun-3.
1425 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1426 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1427 expression (in scope) before reenabling watchpoint.
1428 * signame.c (init_sigs): Add missing declaration of i, fix
1429 sys_siglist declaration.
1430 * source.c (list_command): Fixed range computation to use
1432 * stack.c (backtrace_command): Do not allow command if target has
1433 no stack, print informative error message.
1434 * target.c (target_command): Do not write into command line
1435 because this fails if the target command is used in a user defined
1436 command. [This change was enhanced by gnu to support any-
1437 unique-prefix matching on target names.]
1438 * valops.c (value_struct_elt): Avoid infinite loop on an
1439 erroneous attempt to print the member of function (try p main.p).
1441 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1443 * expread.y (name_no_typename): Avoid reduce/reduce errors
1444 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1445 Since the GDB parser really doesn't use name_no_typename in a
1446 name-only context, the parser can't tell the diff between
1447 names and numbers here. Avoid allowing a name_no_typename
1448 to be a NAME_OR_*INT to resolve the conflict.
1450 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1452 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1454 * valprint.c (val_print_fields): bitfield printing didn't handle
1455 byte order. Indirect through a few more fns to cope.
1457 * values.c (modify_field): also cope with byte order.
1459 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1461 Cleanup for release 3.94.2:
1463 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1464 include files. Roll version to 3.94.2.
1466 * coffread.c (init_stringtab): Read length into unsigned char
1467 array before swapping; don't assume 32-bit longs.
1469 * target.c (target_info): Don't bother with get_sym_file, just use
1470 the symfile global variable.
1471 * symtab.h, symfile.c (get_sym_file): Delete it.
1473 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1474 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1475 (read_type): Replace one more error() with complain().
1477 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1479 * i960-tdep.c: Fix copyright attribution.
1481 * config.gdb: Quote all backquotes in doublequotes. You can
1482 quote me on that. BSD 4.4 shell found this one.
1484 * infptrace.c (throughout): The third argument to ptrace is an
1487 * infrun.c (wait_for_inferior): When program has terminated, we
1488 have to call target_terminal_ours before we pop that target off
1489 the stack (e.g. before a call to target_kill or
1490 target_mourn_inferior). This fixes problem where a program
1491 terminates, then GDB stops for (tty output) and you have to type
1492 "fg" to the shell to resume it. FIXME: This code for what to
1493 do after termination really should be in normal_stop instead.
1495 * gdbcore.h (read_memory_check): Change declaration; it changed
1498 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1499 4.4 prereleases, this avoids a bug in their sgtty compatability
1501 * remote.c: Use terminal.h rather than hand-rolling the same.
1503 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1504 * utils.c (strsave, strstr): Fix arg types.
1505 * valprint.c (val_print): lint
1507 MIPS symbol table support from Per Bothner:
1509 * symfile.c (symtab_fns): Remove initializer table that needs to
1510 be hacked for each new symbol file format supported.
1511 (add_symtab_fns): New function, chains symbol table
1512 handlers into the global list.
1513 (symfile_init): Search this list.
1514 * symfile.h: Add next pointer, declare add_symtab_fns.
1515 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1516 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1518 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1519 symbol *). Thus, we no longer need the hack to trash
1520 pst->filename. Good, since that hack confused code in symfile.c!
1522 (reorder_symtabs, destroy_all_symtabs): Removed static
1523 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1524 Instead, the latter now uses a temporary array (stack-allocated
1525 from an obstack, and then freed).
1527 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1528 haven't been set in the outermost stBlock of a procedure. This was
1529 a problem with f77 binaries on Ultrix 4.?.
1531 (new_symtab, new_symbol, new_type): Continue changing code to use
1532 obstacks more and otherwise conform to dbxread internal style.
1533 Made the free_code of symtabs be free_linetable (as in dbxread)
1534 instead of free_contents. This implies memory leaks when reading
1535 a new symbol table, until the conversion is finished. Did change
1536 (struct symbol) and (struct type) to be allocated on the
1537 symbol_obstack. Blocks and blockvectors are among the things
1540 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1541 tested much, but it solved one problem (reported by Meissner), and
1542 cleans up some other things. The problem happened when an
1543 included file contains actual code (functions) and not just
1544 definitions. The mips coff is a little inconvenient there, since
1545 it may cause a procedure to be mapped to the wrong psymtab.
1547 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1548 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1549 this will need work for the new core paradigm.
1551 Opcode patches from the net:
1553 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1554 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1555 missing altogether - they are added here. From Bruce Bauman.
1556 * mips-opcode.h: The low mask for C0 instructions was too small.
1557 From Garrett Lau. I modified the fix to check the entire 32-bit
1560 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1563 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1565 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1567 * dbxread.c (read_type): Pointer subtraction (value_sub in
1568 valarith.c) sometimes failed because the types of the
1569 pointers being subtracted were not identical.
1570 These differed because dbxread.c was allocating pointer types
1571 using dbx_alloc_type+smash_to_pointer_type instead of
1572 lookup_pointer_type. I failed to find a justification for the
1573 former, so I changed it to use the latter. Similarly, I
1574 replaced smash_to_function_type by lookup_function_type,
1575 and smash_to_reference_type by lookup_reference_type.
1577 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1578 _initialize_mipsread): corresponding changes.
1580 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1582 * source.c (mod_path): Do tilde_expand on each component of the path,
1583 rather than on the (list of) paths as a whole.
1584 (print_source_lines): Set first_line_listed in addition to
1585 current_source_symtab and current_source_line. If the source was
1586 not findable, after a "dir" command to fix the problem,
1587 a "list" would get the wrong lines.
1589 While I was there... (gnu):
1591 * dbxread.c (read_type): Change error to complaint.
1593 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1595 First attempt at detailed understanding of symbol table memory alloc.
1597 * dbxread.c (dbx_symfile_read): Free our string table if we
1598 aren't the mainline. Free the "info" struct since we're done with
1600 (init_psymbol_list): Free any previously allocated psymbol lists.
1601 (): FIXME: Should realloc-down the psymbol lists when done reading
1602 the main symbol file?
1604 * symmisc.c (free_symtab): Free fullname field too.
1606 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1607 (REGISTER_ADDR): Make result type unsigned int.
1609 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1610 define REGEX must also define REGEX1 (its dependency).
1612 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1614 * tconfig/i960: No longer works, points you at vxworks960 or
1617 * xgdb.c, XGDB-README: Remove file. Users can get the much
1619 * Makefile.dist: Remove all trace of xgdb.
1621 * breakpoint.c (breakpoint_1): Pass demangle arg to
1622 print_address_symbolic.
1623 (clear_breakpoints): Remove unused function.
1624 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1625 (breakpoint_re_set): Use catch_errors to do them all anyway.
1627 * gdb-int.texinfo (Host versus Target): Add section on what is
1628 a "host" feature versus what is a "target" feature.
1630 * infcmd.c (path_command, path_info): Handle the PATH variable
1631 (object search path) as conveniently as the source search path.
1632 * environ.c (set_in_environ): Set some vars in GDB's environment,
1633 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1634 * source.c (mod_path): New function, from guts of
1635 directory_command, modifies a path. Used by path_command.
1636 (directory_command): Call it.
1637 * defs.h (strsave): Declare.
1639 * utils.c (sevenbit_strings): Add new printing option.
1640 (printchar): Use it.
1641 (strsave): Provide this handy helper routine.
1642 (set_width_command): Rename set_screen_width_command.
1643 (_initialize_utils): "set screen-width" => "set width";
1644 "set screen-height" => "set height"; add sevenbit-strings.
1646 * infcmd.c (do_registers_info): Print floating point registers
1647 in raw hex as well as float format, regardless of whether it is
1648 a "virtual" convertible register.
1649 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1650 regs as a double, just in case it's being used that way.
1651 * values.c (unpack_long): Comment on array/function coercion.
1652 (unpack_double): Argument is in target byte order now. For
1653 integer arguments, just call unpack_long and float the result.
1654 * m68k-tdep.c: include defs.h for "const" handling.
1655 * remote-nindy.c: Use ieee-float stuff.
1656 (nindy_fetch_registers): Unpack double regs to host double, then
1658 (nindy_store_registers): Pack extendeds to host double, flip
1659 around by misusing unpack_double, send as target double.
1661 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1662 zero, as when stopped at the first instruction of a process.
1664 * blockframe.c: Fix filename in comment (param.h => tm.h).
1665 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1666 * tm-68k.h: Fix typos.
1668 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1670 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1672 * coredep.c (fetch_core_registers): Pass end-address of register
1673 section to register_addr as expected. Don't call supply_register
1674 if we'd just pass it garbage.
1676 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1678 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1680 * target.c (push_target, target_info): Cast enums to int for < or
1683 * stack.c (print_frame_info): Identify source file & line
1684 even if we can't print it.
1686 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1688 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1690 Clean up IEEE floating point support.
1692 * ieee-float.h: New file.
1693 * ieee-float.c: Write real routines to convert between host
1694 doubles and various target IEEE extendeds.
1695 * m68k-xdep.c: Eliminate assembler code for extended floats.
1696 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1697 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1698 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1699 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1700 double_to_ieee_extended.
1701 * i960-tdep.c: Define ext_format_i960.
1702 * m68k-tdep.c: Define ext_format_68881.
1703 * sparc-tdep.c: Define ext_format_sparc, though unused.
1704 * Makefile.dist (HFILES): Add ieee-float.h.
1705 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1708 Obsolete the "coffstrip" program in favor of using BFD's strip.
1710 * nindy-share/coffstrip.c: Remove file.
1711 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1712 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1713 * tconfig/nindy960: Remove reference to coffstrip.o.
1715 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1717 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1719 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1720 * dbxread.c: Remove static symfile_bfd.
1721 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1723 * inftarg.c (child_detach): Pop the child_ops vector if the
1724 detach is successful.
1725 * remote-nindy.c (nindy_create_inferior): Don't push a new
1726 nindy_ops since nindy uses the same one for execution and memory
1728 * core.c (core_ops): Use child_attach and child_create_inferior
1729 rather than default attach and create_inferior functions.
1731 Handle floating point registers in core files.
1733 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1734 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1735 This version untested since BFD doesn't yet support sun3 core
1737 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1738 conventions. Fix comments and style. This version has not
1739 been compiled yet, since we have no HP inhouse.
1740 * core.c (get_core_registers): Look for two sections, ".reg"
1741 and ".reg2", and pass both to fetch_core_registers sequentially.
1743 Revise directory path yet again.
1745 * source.c (forget_cached_source_info): Not static any more.
1746 (init_source_path): New default source path is "$cdir:$cwd".
1747 (dir_command): Handle variable arguments ($cdir, $cwd).
1748 (source_info): Print "Compilation directory" rather than
1749 "Originally compiled in" to remind people of $cdir.
1750 (openp): If the path contains $cwd, use current directory.
1751 (open_source_file): If compilation directory is known, replace
1752 first $cdir in path with the compilation directory.
1753 (print_source_lines): Even if we can't print the lines, set the
1754 current symtab and line for future commands like "info source" or
1755 "breakpoint". Also, error message now contains the file name,
1756 line number, and file access error message.
1757 (_initialize_source): Fix help text to describe changes.
1758 * main.c (cd_command): Forget cached source info when we chdir.
1759 * utils.c (strstr): Add simple implementation.
1761 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1763 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1764 Byte-swap COFF symbol tables if necessary when reading them in.
1765 Use complain() to replace error message in one spot. Needs
1766 corresponding change in bfd/coff-code.h to make some symbol
1767 swapping routines non-static.
1769 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1771 Merge changes from Eirik Fuller, for UTek.
1773 * defs.h (errno): Add declaration.
1774 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
1775 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1776 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1777 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
1778 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
1779 declarations of errno.
1781 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1783 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1784 <rpc/rpc.h> and <rpc/types.h>.
1786 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1788 * i960-tdep.c (examine_prologue): Add new argument limit,
1789 which stops the scan at the end of the prologue, or at the PC.
1790 This fixes a problem where it walks down into the code for the
1791 user's statements if that code looks like function prologues.
1792 Mark Fox and I have been bouncing this code back and forth, making
1793 small changes to it. Callers changed to match.
1795 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1797 Cleanup for gdb-3.94 release final:
1799 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1800 the .c files from vx-share and nindy-share, from the various
1801 macros, since they are not found via ALLDEPFILES.
1802 (SFILES): Add tm-i960.h.
1803 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1804 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1806 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1807 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
1809 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
1811 * am29k-tdep.c: Add contribution line.
1812 (examine_prologue): Cache information about function prologues in
1813 the misc-function-vector to avoid lots of references over the
1814 serial line while examining instructions.
1816 * core.c (core_close): New function made from cleanup_core.
1818 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1819 remote-vx.c, remote.c, target.c, target.h,
1820 Update target_ops vector to add attach, close, and load entries.
1821 Use add_syms_addr_command, not add_file_addr_command, for
1822 add_file. Break out close routine from existing code.
1824 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1825 they are in an obstack.
1826 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1828 (define_symbol): Add symbol type parameter; change callers;
1829 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1830 it to influence the symbol class on the i960.
1831 (define_symbol): Swap LOC_CONST's into target byte order.
1833 * exec.c (exec_close): New function.
1834 (exec_file_command): Call it.
1836 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1837 Fix byte order of frame pointer.
1838 (read_var_value): Result of 0 if var's value can't be found,
1839 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1840 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1841 (locate_var_value): Use read_var_value and use its lazy address
1842 as the location of the var's value. Lint.
1844 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1847 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1848 obsolete Intel versions in favor of vxgdb versions.
1849 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1850 code dealing with byte order of values, which Intel did in host byte
1851 order rather than gdb-4's target byte order.
1852 (i960_frame_chain_valid): Move to nindy-tdep.c.
1853 (examine_prologue, skip_prologue, frame_find_saved_regs,
1854 frame_args_address, leafproc_return, saved_pc_after_call,
1855 pop_frame): Add vxgdb versions from Mark Fox.
1856 (examine_prologue, frame_struct_result_address): Add code
1857 to deal with the saved value of G13 (struct return address
1859 (frame_args_address): Modify Mark's version to prefer the
1860 saved value over the current value in the topmost frame.
1861 Cache result in the frame info to avoid performance hair in
1863 (print_fault): Add gdb960 code for printing faults.
1864 (_initialize_i960): Actually call check_host.
1866 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1867 add stub routines. FIXME, these currently just return zero!
1869 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1870 (attach_command): Call target_attach, not target_open, now.
1872 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1873 (child_attach): Rename from child_open.
1874 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1875 don't confuse it with a zero step_resume_break_address.
1877 * inftarg.c (child_detach): Eliminate inferior_pid test.
1878 (child_files_info): Clean up message a bit.
1879 (child_ops): Use child_attach, not child_open, to attach.
1881 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1882 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1883 findvar.c to here, since it depends on the contents of the
1884 shadow_contents of breakpoints, but keep if #if 0 since it is
1887 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1890 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1891 (ptype_command, display_command): Eliminate have_inferior_p and
1892 have_core_file_p in favor of target_has_stack or
1893 target_has_execution.
1894 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1895 code for actually finding the values of arguments, though we still
1896 keep track of the maximum stack offset for use in printing unnamed
1897 arguments. Handle missing FRAME_ARGS_ADDRESS.
1899 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1900 (struct nindy_regs): Define registers passed to/from nindy.
1901 (nindy_fetch_registers, nindy_store-registers): Translate between
1902 nindy and GDB formats for the registers.
1903 (dcache_init): Statically allocate the cache, since it was being
1904 allocated by a malloc that was never freed anyway.
1905 (nindy_create_inferior): Error, not core dump, if no exec file.
1906 (nindy_before_main_loop): Use target_load, not target_add_file.
1908 * remote-vx.c (net_load): Specify large timeout for load
1909 requests. Allow user to break out with INTERRUPT.
1910 (net_break): Remove useless code, clean up. Change callers.
1911 (parse-args, skip_white_space, find_white_space): Clean up arg
1912 parsing to cope with quoted strings.
1913 (net_wait, net_quit): Never call error, just return status.
1914 (vx_read_register, vx_write_register): Cleanup status checking.
1915 #ifdef the code based on which CPU we are using (960 or 68k),
1916 FIXME, this should be completely general but it isn't yet.
1917 (vx_xfer_memory, vx_resume): Cleanup status checking.
1918 (vx_run_files_info): Improve message.
1919 (vx_load_command): Renamed from vx_add_file_command. Allow load
1921 (net_ptrace): Remove unused routine.
1922 (vx_wait): Adopt code from vxgdb960 to cope with broken
1923 connections to target machine and prompt to disconnect. Remove
1924 debug printouts. Map some EVENT_'s to SIGnals.
1925 (add_symbol_stub, vx_open): Print names of object files we found,
1926 and "ok" if we read their symbols OK. Clarify output in general.
1927 (vx_attach, vx_detach, vx_kill): Add these commands.
1928 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1929 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1930 "info files" output, and create_inferior, since we already have
1933 * stack.c (frame_info): Replace Frame_unknown with 0.
1934 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1935 (return_command): Pop until the PC matches as well as the FP,
1936 so it works even if the FP is shared with another function,
1937 as in "frameless" or "leaf" procedures.
1939 * symfile.c (load_command): renamed from add_file_target_command.
1940 (add_syms_addr_command): renamed from add_file_addr_command.
1941 (add_syms_command): Stub to call target_add_syms.
1942 (_initialize_symfile): Change command names and descriptions,
1943 add-file => add-syms, and load from alias to its own command.
1945 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1946 maybe_kill_then_create_inferior): Default for attempts to start
1947 a process, if one is already running, is to ask about killing
1948 it and retry if yes.
1949 (upstack_create_inferior): #if-0 it, strata obsolete it.
1950 (push_target, unpush_target, pop_target): to_close() a target
1951 before unstacking it.
1952 (target_info): Renamed from target_files_info.
1953 (_initialize_targets): Rename "i files" as "i target", accessible
1956 * target.h: Improve comments about the target_ vectored routines.
1958 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
1959 Convert commenting style to standard GNU style.
1960 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
1961 (SKIP_PROLOGUE): No longer a no-op.
1962 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1963 (*_REGNUM): Sort register numbers.
1964 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1965 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1966 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1967 are now 10 byte extendeds, not 8 byte doubles.
1968 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1969 for nindy versus vxworks targets. FIXME, this should possibly go
1970 in the target vector.
1971 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1972 frame_saved_regs and arg pointer with each frame.
1973 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1974 (FRAME_ARGS_ADDRESS): Use cached result.
1975 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1976 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1977 (PRINT_RAMDON_SIGNAL): Call print_fault.
1978 (POP_FRAME): Now works.
1980 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1981 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1982 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1983 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1986 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1987 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1989 * valarith.c (value_subscripted_rvalue): Avoid handling
1990 floats and doubles specially; it gave alignment errors. Lint.
1992 * valops.c (value_of_variable, value_of_this): Error if unknown
1995 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1996 to avoid alignment problems.
1997 (value_print): Handle unknown value address.
1998 (cplus_val_print): Two args are ignored; remove them. Change caller.
1999 (val_print): Use unpack_long rather than pointer-deref.
2002 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
2003 to avoid alignment problems.
2004 (value_being_returned): Error if return value unknown.
2005 (set_return_value): Add bogosity warning, FIXME. *
2007 * TODO: A woman's work is never done.
2009 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
2010 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
2011 Add ieee-float.o to OBS.
2012 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
2013 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
2014 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
2016 Changes to generalize the VxWorks RPC protocol slightly, to handle
2017 i960 as well as 68000.
2019 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
2020 * vx-share/reg.h: Produce i960 regs #ifdef I80960
2021 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
2022 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
2023 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
2024 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
2025 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
2026 so they will move in target byte order rather than network
2027 byte order (happens to be the same).
2029 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2031 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
2033 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2036 Add contribution lines to various files, showing where they
2039 * breakpoint.c (break_insn, check_break_insn_size,
2040 read_memory_nobpt): Remove to mem-break.c.
2042 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
2045 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
2046 entry has bad register number. This change is not
2047 tested in this release, FIXME.
2049 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
2052 * value.h: Force value's contents field to be aligned to hold
2053 at least a double or a long long (if supported). This avoids
2054 doing bcopy's in and out of the contents field.
2056 (step_1): Avoid coredump under obscure circumstances when we
2059 * symtab.h (misc_info): Add field to misc function vector for
2060 any kind of cached information the target code desires. AMD
2061 29000 uses this to avoid repeating examine_function_prologue's.
2063 * coffread.c: Lint. Remove static symfile, read_section_header.
2064 core.c (have_core_file_p): Lint: remove.
2065 expprint.c (print_subexp): Lint.
2066 infptrace.c, valops.c, valprint.c: lint.
2068 Roll in changes from vxgdb-5.0.1:
2070 * symtab.h: Comment byte order of each address class. Add
2071 LOC_LOCAL_ARG for frame-relative args (960).
2072 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
2073 symtab.c, symmisc.c: ditto.
2075 * infrun.c (init_wait_for_inferior): Clear stop_signal.
2077 * remote.c (remote_resume): Error if resume with a signal.
2079 * symfile.c (prim_record_misc_function): Clear misc_info.
2080 (fill_in_vptr_fieldno): Check stub type of arg.
2082 * valops.c (value_cast): Avoid looking up names of types whose
2083 name we don't know, to prevent coredump. Sun CC produces typedef
2084 rtx and the name of *rtx is zero...
2086 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2088 Roll in changes from final AMD 29000 port (Tiemann).
2090 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
2091 for ../include/a.out.encap.h. This might not work now that BFD
2092 is separately compiled. Instead, BFD support for encap will have
2093 to translate machine type 29k into the right COFF_MAGIC.
2095 * infcmd.c: Remove references to inferior_pid that aren't used
2096 in actual ptrace calls; use target_has_execution, etc.
2097 (have_inferior_p): Remove function.
2098 (program_info): Print target info rather than "process number";
2099 avoid gratuitous messages unless from_tty.
2100 (run_stack_dummy, finish_command): Set proceed_to_finish.
2101 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
2102 main.c: Lint. Lose have_inferior_p().
2103 inferior.h (have_inferior_p): Remove, lint.
2104 (proceed_to_finish): Add flag to ask that all regs be saved
2105 by normal_stop, for the few commands that need it, speeding up
2106 serial I/O. Add comments to stop_registers.
2108 * remote-eb.c: Remove newline from breakpoint message we grep
2109 for. Never time out when running the user program.
2113 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2115 Roll in changes from vxgdb-5.0.1:
2117 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
2118 symbol in its raw form, we are processing an unlinked ".o" file.
2119 See if the target environment has assigned it an address, using
2120 target_lookup_symbol (VxWorks does), and enter it into the symtab
2123 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
2124 68k versions for a simpler version that assumes zero FP at bottom.
2125 Fixes bug of truncated stack reports.
2127 * target.h (target_lookup_symbol): Define this routine's args
2128 and result, finally.
2130 * target.c (nosymbol): Default routine for target_lookup_symbol.
2131 (target_default): Default lookup_symbol and call_function too.
2132 (files_info): Only print has_all_memory warning if a non-dummy
2135 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
2136 vx_convert_from_virtual): If target does not have floating point,
2137 zero register "values", and avoid doing cross-net conversions.
2138 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
2139 (vx_open): Rearrange code that attaches to target and reads
2140 symbols for all loaded modules, to work if some of the modules
2141 are not accessible. Add symbol_stub() and add_symbol_stub()
2142 as callbacks from catch_errors(). Allow connect attempt to be
2143 interrupted painlessly with ^C (FIXME, there are still some bugs
2144 if the interrupt happens during symbol reading.). Print
2145 final message with puts_filtered, since symbol messages are
2150 * main.c (catch_errors): Only print errstring if non-null.
2151 (command_loop): Avoid an ioctl per command to test ISATTY.
2153 * remote-vx.c (net_load): make static; avoid sophomoric msg.
2154 (vx_xfer_memory): Return correct result!
2155 (vx_files_info): Indicate whether target has float or not.
2156 (vx_lookup_symbol): Complain, not error, if target gone.
2157 (vx_open): Print "Connected" msg before disabling immediate-quit.
2158 [FIXME: lookup_symbol and vx_open changes need testing.]
2160 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
2161 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
2162 contributor lines and update copyrights to 1991.
2164 Changes from an attempted H-PUX host port:
2166 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
2167 defines PT_ATTACH and PT_DETACH but not PT_KILL.
2168 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
2169 * remote-vx.c: include <sys/time.h> for HPUX.
2170 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
2171 "core_file_command" routine to BFD regime. May not work yet.
2173 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
2175 * xgdb.c: Replace X10 version with some VJ version.
2176 (FIXME: Its copyright assignment is not on record.)
2177 * xgdb.c: Update include files to X11R4 (Xaw crud).
2178 (xgdb_display_source, create_text_widget): fix call to
2179 get_filename_and_charpos. Rewack source window stuff for X11R4
2180 (gleaned from include files, and "nm's" of binary libraries, since
2181 I had no doc available).
2182 (append_selection, append_selection_word): Disable with FIXME
2183 since R4 changed interface here.
2184 (create_buttons): Add back the old set of buttons.
2185 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
2187 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
2188 Roll VERSION to 3.94 (not yet final though).
2190 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2192 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
2193 obstack_int_grow, obstack_int_grow_fast): Eliminate
2194 cast on left of assignment, which gives MIPS cc fits and is
2197 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
2198 F_ALIAS. Use printf, not fprintf, when not passing a file
2200 (compare_opcodes): Check that identical instructions have
2201 identical opcodes, complain otherwise.
2203 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
2204 was reported by Roland McGrath.
2205 (unimp): Only match if exactly zero instruction. (Roland)
2206 (branches and traps): Generate all variations of these
2207 instructions with macros, based on a single call that defines
2208 each condition name and its binary representation.
2209 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
2211 * valprint.c (val_print_fields): Take, and use, format parameter.
2212 This means that "p/x struct" again prints the elements in the
2213 desired format. Changed callers.
2215 * stack.c (frame_info): Use filtered output, and indicate wrap
2216 points. Remove kludgy formatting designed to avoid line wrap.
2218 * utils.c (wrap_here): If the line is already full (because
2219 we had printed a long indent or long wrapped string), do an
2220 immediate newline-and-indent.
2222 * m68k-pinsn.c (print_insn_arg): Bugfix from
2223 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
2224 instruction is incorrectly disassembled as bkpt #8.
2226 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
2227 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
2228 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
2229 and then will dump core (sometimes). I traced it back to an
2230 uninitialized symfile_name in psymtab_to_symtab.
2231 (const_vol_complaint): Add quotes to message.
2232 (define_symbol): Only believe line number if gcc_compiled.
2233 Avoid allocating symbol if we will not return it.
2235 Add target strata support so that newly established targets go
2236 into their right place in the target stack (e.g. a new exec file
2237 doesn't wipe out the ability to access the running process).
2239 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2240 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2241 and initialize it properly in all the targets.
2243 * target.h: Document strata. Change return type of push_target.
2245 * target.c (nomemory): new function for dummy memory access.
2246 (tcomplain): Rename complain, now also used in symfile.c.
2247 (push_target): Push targets within strata. New return value shows
2248 whether new target is on top of stack or not. Always keep dummy
2250 (target_files_info): Ignore dummy target.
2252 * core.c (core_open): Warn user, and skip accessing file, if the
2253 core target is not the topmost target in the stack.
2254 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2257 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2258 target_ops, it doesn't belong there since we have no regs there.
2259 Change name of target from machine => memory to clarify.
2261 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2263 * Freeze version 3.93 for release.
2265 * Makefile.dist: Handle vx-share and nindy-share subdirs
2266 properly when building gdb.tar.Z.
2268 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2269 printed in various places, so I could change just one copy.
2271 * dbxread.c, coffread.c: Change references to bfd->iostream
2272 to cast to FILE *, now that BFD avoids needing types defined
2273 in other header files.
2275 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2277 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2278 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2279 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2280 (actually gcc -Wall).
2282 * dbxread.c: Remove first_global_sym, last_global_sym, since
2283 they are never referenced.
2285 * defs.h (baud_rate): Declare.
2286 main.c: Define it, and add the -b option to set it.
2288 * gdb-int.texinfo: Add text on how to define a new host or target
2289 architecture, prompted by Per Bothner's questions about MIPS
2292 * gdb.texinfo: Document "complaints". Change doc of -q since
2293 gdb no longer prints the copyright and blurb if you specify a file
2294 name to be debugged (just like Emacs). Add doc for Nindy-specific
2295 command line flags for specifying target serial port and such.
2296 Update copyright to 1991.
2298 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2299 has taken over for us the job of ripping up executable files. The
2300 crud caused Per Bothner's port to not compile.
2302 * infrun.c (normal_stop): Avoid printing "Program exited
2303 normally" if we are in batch mode. This allows a GDB which
2304 executes a program on a target system, to behave like a Unix
2305 command (input from stdin, output to stdout, no extraneous
2308 * main.c (main): Allow additional machine-dependent command line
2309 options to be specified with the ADDITIONAL_OPTIONS,
2310 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2311 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2312 processing to occur just before the main loop with
2313 BEFORE_MAIN_LOOP_HOOK.
2314 (main): If a "core file" argument is specified, and it is not a
2315 core file, try it as a process ID to attach.
2316 (symbol_completion_function): Attempt to cope with
2317 "show screen-" TAB, not very successfully. This needs more work,
2319 (batch_file): New function, returns whether we are reading
2320 commands from an interactive tty on stdin, or from somewhere else.
2321 Called by normal_stop since it doesn't get from_tty passed down
2322 to it like many commands do.
2324 * remote-nindy.c: Handle command line options for nindy
2326 (nindy_before_main_loop): Prompt user for tty name if they
2327 don't specify it before getting to the interactive command loop.
2329 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2330 and -r command line options. Also add hook before main loop
2331 to make it easy to specify a tty.
2333 * TODO: More things to do, one done.
2335 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2337 * dbxread.c: Make complaint() calls pass pointer, not struct.
2338 Add complaints about badly formatted C++ type information
2339 (const/volatile indicator, and parse errors resulting in
2340 error_type). Fix C++ virtual member fn comment.
2341 (read_struct_type): Avoid bumping pointer if we got a parse
2342 error; this prevents our walking beyond the end of a string.
2343 Terminate loop on null char as well as semicolon.
2344 (process_one_symbol): Fix the LBRAC fix so that it uses the
2345 last previous SLINE, FUN, or SO record's PC address. C++ debug
2346 symbols did not have SLINE records in a useful order compared
2347 to the LBRAC records.
2348 (define_symbol): Handle "catch" records.
2350 * symtab.c (check_stub_type): Added new complain
2351 `stub_noname_complain' and added a consistency check to
2352 keep the debugger from crashing when finishing from an
2353 exception frame. A real fix will be needed later.
2355 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2357 * infcmd.c (attach_command): Make global.
2359 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2360 but make them easy to comment out. Perhaps later they should
2361 be enabled by what CPU you configure for? FIXME.
2362 (VERSION): Roll to 3.93.
2363 (pinsn.o): Remove rule for obsolete file.
2364 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2366 Run down a problem that manifested by printing the wrong function
2367 name in stack traces of read_ofile_symtab. Turned out that the
2368 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2369 the LBRAC symbol with an address in the *data* segment, which
2370 blew our binary search through the blocks.
2372 * dbxread.c: Use the complain() facility consistently to bitch
2373 about problems in the symbol file we are reading.
2374 (finish_block): Add code to check the nesting of the blocks;
2375 complain and Procrust them to fit if wrong.
2376 (make_blockvector): Check the order of the blocks, complain
2377 [but don't cope] if wrong.
2378 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2379 symbols to be sure their PC value is greater than the last SLINE
2380 (line number) symbol we've seen, complaining and adopting the
2381 SLINE PC value if wrong.
2383 * symfile.h (struct complaint, complaint_root, complain,
2384 clear_complaints): Add.
2385 * symfile.c (complain, complaint_root, clear_complaints): Add
2386 facility to deal with non-fatal complaints and to regularize their
2388 (symbol_file_add): Clear complaint counters to allow new complaints.
2389 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2391 * dbxread.c (dbx_symfile_read): Remember the address and size
2392 of the string table for the main symbol file, so we won't read it
2394 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2395 to avoid reading the string table yet again. Lint.
2396 (throughout): Improve filtered output, including word wrap.
2397 (read_range_type): Improve Bothner's fix to handle other types too.
2399 * utils.c: Improve line wrap implementation. Handle unlimited
2400 width by making chars_per_line unsigned.
2401 (puts_filtered): New, easy, function.
2403 * defs.h (puts_filtered): add.
2405 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2406 call the identical sort_symtab_syms() in symfile.c instead.
2408 * expread.y: Suggest the `file' command rather than `symbol-file'.
2410 * command.h (enum var_types): Add zinteger for seroable
2412 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2413 nested if's into a switch.
2415 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2416 we did not stop because of a breakpoint (it must have been for
2417 some other reason, like a "stepi"), so don't print anything.
2419 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2420 doesn't include <sys/types.h>, old SunOS's require it for
2423 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2425 A test port of gdb-3.92.6 to the Sony NEWS.
2428 Don't normally link in remote- or vx stuff.
2429 Some of it doesn't compile, and it wastes space for 99% of the users.
2430 Remove reference to no-longer-used HAVE_VPRINTF.
2431 Fixed BFD_DEP typo to BFD_DIR.
2433 Fix cast in arg to bfd_h_getlong.
2434 Make char *prefix be const.
2435 Fix how certain range types are mapped into builtin unsigned int types.
2437 Remove 2 #includes. They cause errors (on Sony, at least),
2438 and aren't needed (they wern't in earlier versions).
2440 print_address_symbolic should never demangle labels
2441 (since it prints *assembler-level* labels).
2443 [This was superseded by the change to printcmd below.]
2446 Add some "volatile" return types to avoid warnings.
2447 If MISSING_VPRINTF add vprintf function and not just macro
2448 (since vprintf is used in printcmd.c).
2450 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2451 (The latter isn't grokked by some PCC-based compilers.)
2453 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2455 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2456 * nindy-share/coffstrip.c
2457 Added some forward declarations (otherwise, gcc complains
2458 about implicit extern redefined as static).
2460 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2462 Changes inspired by Per Bothner:
2463 * printcmd.c (print_address_symbolic): Take additional parameter
2464 specifying whether to demangle.
2465 (print_address): Pass in asm_demangle to control demangling.
2466 (print_address_demangle): New fn, takes explicit arg to control
2468 * utils.c: Add new vars demangle and asm_demangle, and let them
2470 (fputs_demangled): If !demangle, just print the argument.
2471 (fprint_symbol): If !demangle, just print raw symbol.
2472 * valprint.c (val_print): Call print_address_demangle rather than
2473 print_address, to cause demangling to depend on the global
2474 rather than assembler-level demangling setting.
2475 * WHATS.NEW, gdb.texinfo: Document.
2477 * main.c (show_command): Show all settings if no arg.
2478 (initialize_main): Make "info set" the same as naked "show".
2479 * command.c (cmd_show_list): Handle prefix commands in the
2480 list, and print the name of the setting as well as its English
2481 description and value.
2483 Allow gdb functions to specify where a line should wrap if it
2484 exceeds the size of a terminal line. Use it to make the output
2486 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2487 of the right size when screen width changes.
2488 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2489 (wrap_here): New fn, indicates a point in the output where we
2490 should wrap the line rather than just letting it overflow at a
2492 (fputs_filtered): Implement wrapping.
2493 (n_spaces): New fn, returns a pointer to N spaces.
2494 (print_spaces_filtered): Use n_spaces.
2495 * defs.h (n_spaces): Declare.
2496 * stack.c (print_frame_info): Wrap with 4-space indent after
2497 fn name and before filename and line number.
2498 * printcmd.c (print_frame_args): Wrap with 4-space indent
2499 before each argument name is printed.
2500 * valprint.c (value_print): Wrap with no indentation before
2502 (val_print_fields): Wrap with indentation relative to nesting
2503 level before each field name.
2504 (val_print): Wrap with nesting indentation before array elements.
2505 * command.c (do_setshow_command): Avoid extra newlines,
2506 wrap with 4-space indent around values printed, end with period.
2507 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2509 * breakpoint.c (breakpoint_1): Implement addressprint for
2510 "info breakpoints" display. Change file name and line number
2511 format to " at file:nnn" rather than " (file line nnn)".
2512 * gdb.texinfo: Document.
2515 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2517 Frozen for gdb-3.92.6 release.
2519 README, WHATS.NEW: Update for 3.92.6 release.
2521 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2522 coffread.o from configs since it is now built by default.
2523 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2524 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2525 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2526 from configs since it is now built by default.
2528 Makefile.dist: Update for release 3.92.6. Handle files that
2529 have been moved to ../include, ../getopt, or ../bfd. Add
2530 saber.suppress and tests directory. Add config.status to
2531 the release (it will say "none").
2533 coredep.c: Minor formatting fixes.
2535 These changes were made in early December but only checked in now:
2536 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2537 nindy-share/nindy.c: lint
2538 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2539 register values coming back from the target; we store values
2540 in target byte order everywhere.
2542 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2544 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2546 * valprint.c (cplus_val_print, val_print_fields): New functions,
2547 which print C++ objects. They conspire to avoid printing a
2548 virtual base class more than once, following all the twists and
2549 turns of C++ virtual base rules.
2550 (val_print): Call the above rather than do it by hand.
2552 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2553 symbol file, not for added files like shared libs. This really
2554 needs to be generalized to a timestamp per file.
2556 * core.c (cleanup_core): Avoid coredump if no core file.
2558 * config.gdb: Accept -host or -target in place of +host or
2561 * coffread.c (find_linenos): Avoid desupported BFD interface
2562 to line numbers. We still read them manually rather than using
2563 BFD's "generic" features.
2565 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2567 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2569 * Makefile.dist: Eliminate use of $< in explicit targets.
2571 * readline/Makefile: Use $< rather than $*.c, which does not
2572 include the VPATH in GNU Make.
2574 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2575 copies of tconfig/i960, added for global configuration
2576 compatability. All i960 versions can read both coff and b.out.
2578 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2579 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2582 * TODO: Think of more things to do.
2584 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2586 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2587 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2588 64-bit float conversion.
2590 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2591 equivalent to sun?os4 so global config works.
2593 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2595 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2597 * main.c: Only declare linesize once; declare pagesize not at
2598 all, since it is never used.
2599 (main): Clear newly allocated line before it is used.
2601 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2603 Further stabilization for the Intel 960.
2605 * Makefile.dist: Parameterize the location of the "include"
2606 and "bfd" directories, as well as "getopt". Add symfile.c.
2607 Link in both dbxread and coffread. Fix up "make depend" to
2608 rewack the locations of include, bfd, and getopt in its output.
2610 * README: Document moving include files, improve some of
2613 * coffread.c: Move common code out to symfile.c. Change
2614 symbol_file_command style interface to use new *_symfile_init
2615 and *_symfile_read interface under BFD. Use BFD internal
2616 info to locate line table, symbols, etc.
2618 * core.c (core_fetch_registers): Rename to get_core_registers
2619 to avoid confusion with fetch_core_registers.
2620 (register_addr): Move to coredep.c, which is already machine
2621 dependent. This leaves core.c pretty clean of dependencies.
2623 * coredep.c (register_addr): Accept this routine from core.c.
2625 * dbxread.c: Move common code (with coffread.c, etc) into new
2626 symfile.c. Each psymtab now contains a pointer to the
2627 format-dependent function that knows how to read it in. Make
2629 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2630 (process_one_symbol): Add code to complain about a "compiler bug
2631 we muzzle here", if we actually see it.
2633 * eval.c (evaluate_subexp): Insert missing "break" statements
2634 in code that determines whether a variable is an lvalue in
2635 memory, register, or whatever. I detected this via a compiler
2636 bug in which it *almost* mashed out the whole switch statement.
2638 * gdb-int.texinfo: Add minor sections on configuring gdb for
2639 release, and about the README file.
2641 * infcmd.c (registers_info): Fix formatting somewhat. Still
2642 not as pretty as before, but it handles byte swapping.
2644 * remote-nindy.c: If data cache routines are interrupted while
2645 waiting for the remote end, be sure that any uninitialized cache
2646 blocks are on the free list, not on the valid list!
2648 * symfile.h: Flesh out this header file with all the various
2649 routines and variables that have been merged in from dbxread.c
2650 coffread.c, and symtab.c to symfile.c.
2652 * symfile.c: New file, containing code common to dbxread.c,
2653 coffread.c, and some code from symtab.c. All generic code for
2654 reading symbol files should be in here now.
2655 (unrecord_misc_function): Remove unused function.
2657 * symtab.h: Remove file-reading things to symfile.h.
2659 * symtab.c: Remove file-reading things to symfile.c.
2661 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2662 to decode i960 fault types.
2664 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2665 target.c: Change type of the "resume" function from int to void,
2666 since its result was never used.
2668 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2670 * main.c: Replace "stupid" with "caution"; you now "set caution
2673 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2675 * infcmd.c (do_registers_info): Call val_print to deal with the
2676 byte order of the registers being printed. FIXME, this makes
2677 the formatting of the output uglier.
2679 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2680 defined, call it for signals the debugger doesn't itself use.
2681 The i960 uses this for more detailed fault information.
2683 * remote.c (remote_open): If arg is null, print help rather than
2686 * sparc-xdep.c (register_valid): Avoid declaring size, since
2687 various modules will think of various sizes depending on the
2688 architecture of their tm-file. FIXME, we need protection against
2689 actually entering one of those modules, which would clobber
2690 storage if not for the target architecture compiled into gdb.
2692 * stack.c (up_command, down_command): Always print the frame
2694 (up_silently_command, down_silently_command): New commands
2697 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2699 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2700 more parameters than it used to.
2702 * findvar.c (registers): Increase slop to 256 bytes, which should
2703 protect us against even most RISC machines with large register
2705 (locate_var_value): Move declaration inside related ifdef.
2707 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2708 throughout, to avoid throwing away buffered input from the board.
2709 (nindy_wait): Supply_register takes addr_of_value, not value.
2710 (i960_print_fault): Renamed from i80960_fault.
2711 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2712 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2714 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2715 we can set the PC in the call to proceed(). Unpush nindy_ops
2716 before pushing it on top, to avoid message to user. Eliminate
2717 commentary from Unix machines that just misleads here.
2718 (reset_command): Fix error message to suggest target command.
2720 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2722 Release 3.92.5 as frozen.
2724 Stabilize the merged release...with help from lint, Saber C,
2727 Everywhere: Add include files needed to declare return types
2728 of functions called.
2730 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2732 * breakpoint.h: Add undeclared breakpoint functions, and some
2733 functions for display handling since I couldn't think of a better
2736 * breakpoint.c (insert_breakpoints): Make code for disabling
2737 shared library bkpts more likely to work. It's used when we
2738 rerun a program and stop before the shared library has been
2740 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2741 cast from pointer, so it squeezes through catch_errors.
2742 (bpstat_stop_status): Fix logic broken some time ago. We now
2743 always create a bpstat if the stop address matches a breakpoint,
2744 even if we don't stop there -- just like the old code used to do
2745 before I got my fingers into it (sigh).
2746 (breakpoint_1): Print "ignore count" after "stop only if"
2747 condition, since that's how it actually works.
2748 (mention): Handle watchpoints as well as breakpoints.
2749 (watch_command): use set_raw_breakpoint and mention to do most
2750 of the work (and initialize all the fields!). Only pass one
2751 arg to parse_c_expression, since that's all it takes.
2753 * command.c (not_just_help_class_command): Rename arg to args
2754 since we ignore "unused argument" warnings on vars named "args".
2755 inflow.c (child_terminal_info): ditto.
2756 infptrace.c (kill_inferior): ditto
2757 main.c (catch_errors, version_info, quit_command, pwd_command,
2758 source_command, dump_me_command, editing_info,
2759 set_history_size_command, set_history, show_history,
2761 stack.c (locals_info): ditto
2762 target.c (target_files_info): ditto
2763 valprint.c (set_input_radix, set_output_radix): ditto
2765 * core.c: Remove old variables for handling core and exec file
2766 sections (data_start, data_end, stack_start, stack_end,
2767 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2768 text_end, exec_data_start, exec_data_end, text_offset,
2769 exec_data_offset, data_offset, stack_offset). They're
2770 superseded the more general build_section_table and
2772 (get_exec_file): Mention the `file' command.
2773 (read_memory_check): Rename to memory_error, and only call it
2774 in the case of an actual error.
2775 (read_memory, write_memory): call memory_error.
2776 (core_fetch_registers): Register section name is ".reg".
2778 coredep.c: Remove a bunch of crud now that all this file does
2779 is pull the registers out of a core file.
2780 (fetch_core_registers): Rewrite to actually work, I hope.
2782 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2783 Replace index() with strchr(). Remove all the pre-BFD macro
2784 definitions for accessing the symbol file.
2785 (struct dbx_symfile_info): Encapsulate the information that
2786 dbx_symfile_init needs to pass to dbx_symfile_read in this
2789 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2790 dbx_symfile_discard): Rearrange symbol file reading to divide
2791 the format-specific part from the format-independent part,
2792 leaving the format-independent part such as file name expansion
2793 and opening in symtab.c. This replaces
2794 partial_symbol_file_open and partial_symbol_file_read.
2795 Symbol_file_read, add_file, add_file_target_command,
2796 add_file_addr_command move to symtab.c. Pass an explicit
2797 "mainline" flag for when reading the main symbol table, rather
2798 than relying on the offset address to be zero or nonzero.
2800 (dbx_symfile_read): Don't allow void *'s to be printed as
2802 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2803 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2804 macro" debug version really work.
2805 (read_dbx_symtab): Remove unref'd parameter inclink.
2806 Avoid swapping N_SLINE symbols, for speed.
2807 Merge N_TEXT!N_EXT case with the other external symbol
2808 definitions' case. Add comments.
2809 (start_psymtab): Allocate the symfile name in the psymtab on
2810 the psymbol_obstack, rather than using the caller's storage.
2811 (end_psymtab): Only allocate a dependencies list if there are
2813 (psymtab_to_symtab_2): Use BFD when reopening file to read
2814 its symbols for real.
2815 (read_struct_type): Add FIXME comments where it needs work
2817 (read_huge_number): Add FIXME about overflows.
2818 (read_range_type): Add FIXME about comparing a long to 1<<32.
2820 * coffread.c: Minor changes to move things closer to the new
2821 regime with symtab.c and dbxread.c Major work is still needed
2824 * exec.c (exec_file_command): Remove old variables (see core.c
2826 (xfer_memory): If memory transfer is right at the end of a
2827 section, don't lose.
2829 * findvar.c (get_saved_register): If value is in a real
2830 register, LVAL is lval_register, not lval_memory.
2832 frame.h: Declare print_sel_frame and record_selected_frame.
2834 gdb-int.texinfo: New file, for GDB internals documentation.
2835 Very simple, unformatted doc of cleanups is there for now.
2837 gdbcore.h: Remove obsolete variables that described a.out
2838 section addresses and offsets. (See core.c above.)
2839 Declare fetch_core_registers and registers_fetched.
2841 getopt.c: Declare char *alloca(); even on SPARC.
2843 infcmd.c (run_command): Call target_kill rather than
2845 (step_command, next_command, stepi_command, nexti_command):
2846 Declare from_tty parameter even though we don't use it.
2847 (run_stack_dummy): argument BUFFER is a char array, not
2848 a pointer to REGISTER_TYPE.
2849 (finish_command): using_struct_return needed a value *,
2850 not a struct symbol *.
2852 * infptrace.c (child_xfer_memory): To avoid dependency on
2853 where sections are in memory, try PT_WRITE_D and if that fails,
2854 try PT_WRITE_I. Most Unixes don't care which you use.
2856 * infrun.c (step_resume_break_shadow): Change to array to
2857 match other breakpoint shadow storage.
2858 (clear_proceed_status): Pass address of bpstat to
2859 bpstat_clear, not the bpstat itself.
2860 (child_create_inferior): FIXME comment about if the child
2862 (start_inferior): Remove old function.
2863 (child_open): Use target_kill rather than kill_inferior.
2864 (wait_for_inferior): Ditto.
2865 (insert_step_breakpoint, remote_step_breakpoint): Use
2866 new step_resume_break_shadow.
2868 * inftarg.c (child_wait): If all child processes die,
2869 pretend that the one being waited for exited with signal 42.
2871 * main.c (command_line_input): When scanning for comments,
2872 don't coredump on unclosed quotes.
2873 (quit_command): Use target_kill rther than kill_inferior.
2874 (_initialize_main): Rename class_user from "user" to
2877 * printcmd.c (print_command_1): Initialize "fmt" if no format
2878 is specified by the user.
2879 (print_frame_args): Only add to args_printed if we are
2880 actually fetching args from the stack (avoiding undefined
2882 (_initialize_printcmd): Remove bogus \{ from string.
2884 * remote-eb.c (eb_open): Avoid coredump on no argument.
2886 * remote-nindy.c: Bring out of Intel environment into new
2887 target environment. Remove all conditional compilation on
2888 I80960. Massive hacking throughout.
2889 (nindy_xfer_inferior_memory): New routine stolen from
2891 (nindy_create_inferior): New routine pieced together, probably
2892 not quite working yet.
2893 (nindy_ops): New target_ops struct for nindy.
2895 * remote-vx.c: Use write_memory rather than target_write_memory
2896 to get error checking.
2897 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2899 (vx_create_inferior): Use target_terminal_ours...
2901 * signame.c (_initialize_signame): Always initialize, since
2902 we need the table for things other than psignal.
2904 * solib.c (solib_add): Use symbol_file_add, not add_file.
2905 (solib_address): Return boolean result rather than struct
2906 pointer which nobody else knows the type of.
2908 * sparc-tdep.c, valops.c: Use write_memory rather than
2909 target_write_memory, to get error checking.
2911 * stack.c (locals_info, catch_info, args_info,
2912 get_selected_block, frame_command, up_command): Use
2913 target_has_stack, rather than have_inferior_p or
2916 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2918 * symfile.h: New file, defining the interface between the
2919 generic and object-file-specific symbol reading code.
2921 * symtab.c: Move generic symbol-reading interface to symtab.c,
2922 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2923 table to map BFD targets to symbol-reading modules in GDB.
2924 Change index to strchr.
2925 (lookup_struct_elt_type): Use error() rather than hand-made
2926 simulations thereof.
2927 (lookup_partial_symbol): Speedup slightly when length == 0.
2928 (symbol_file_add): New function.
2929 (symbol_file_command): Call it.
2930 (symfile_open, symfile_init): New function.
2931 (add_file_target_command, add_file_addr_command): moved from
2934 * target.c (target_command): use target_kill.
2936 * target.h (target_files_info): Don't declare, never called
2939 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2940 files to determine stack end address.
2942 * valarith.c (value_x_binop, value_x_unop): Change error message
2943 to be more useful. Pass proper argument to value_struct_elt.
2945 * valops.c (value_assign): FIXME comment that long long
2946 bitfields will break here.
2948 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2949 Update `make saber_gdb' to work better.
2951 * TODO: A woman's work is never done.
2953 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2954 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2955 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2956 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2957 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2958 valops.c, valprint.c, exec.c: Lint.
2961 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2963 Continuing Intel 960 port merge of GDB.
2965 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2966 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2967 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2968 Wack over "make depend" so it handles files in subdirectories
2969 vx-share, nindy-share, bfd, and in the current directory.
2971 * blockframe.c (get_prev_frame_info): Remove fatal error
2972 if stack not defined.
2974 * core.c (core_open, core_detach): New functions that handle
2975 the old "core-file" command as "target core" and "detach" instead.
2976 (core_file_command): Call them.
2977 (core_xfer_memory): Use common routine xfer_memory.
2979 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2980 dbxread now uses bfd for everything but symbol reading itself.
2981 BFD internals are used to drag out the relevant file offsets.
2982 (partial_symbol_file_open): Change args all around for BFD.
2984 * symtab.c: Rename "value" to "val" everywhere, so we can
2986 (symbol_file_command): New command, moved from dbxread.c
2987 and coffread.c. It uses BFD to read the file, then vectors
2988 based on its type, to dbx or coff symbol readers.
2989 * symtab.h: Extern a few vars for symbol_file_command.
2991 * target.h: Breakpoint takes a char * save area, not a char **.
2993 * valprint.c (val_print): When unpacking bitfields, offset
2994 the address in gdb of the value, if it is declared with a shorter
2995 type. Remove the last "runtime kludge test" of host byte order.
2997 * utils.c: Remove old my_bfd_read routine.
2999 * stack.c (frame_info): Use target_has_stack. Print program counter
3000 register's actual name rather than "pc", since it's called the
3001 "ip" (instruction pointer) on the i960 (sigh).
3003 * target.c (target_command): Add command for selecting a target
3004 type and calling its open routine. This is used for initiating
3005 communication with a particular target, in a generic way.
3007 * tm-i960.h: Update for modern gdb. Remove semicolons from
3008 various macros. Handle reading struct return convention, and
3009 error-out attempts to return structs with the "return" command.
3010 Be sure gdb doesn't think we know how to call functions in the
3013 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
3014 to i960_xxx in lower case.
3015 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
3016 not being defined yet.
3018 * remote.c (remote_open): Call start_remote to initialize
3019 wait_for_inferior during open.
3020 (remote_xfer_inferior_memory): Return length written rather
3023 * remote-vx.c (target_command -> vx_open): Use new generic
3025 * remote-eb.c, inftarg.c, exec.c: ditto.
3027 * infrun.c: Fix comments.
3028 (attach_program -> child_open): Use new generic target command.
3029 (wait_for_inferior): Clear saved register values before target_wait,
3030 so target_wait can set some of them if convenient.
3032 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
3033 Return success indicator, not void.
3034 (child_xfer_memory): Avoid fetching initial word if we'll
3035 overwrite it anyway.
3037 * infcmd.c (attach_command): Use new generic target open routine.
3038 (_initialize_infcmd): Update doc on attach and detach commands.
3039 (do_registers_info): Merge in a byte-order problem as a FIXME
3042 * findvar.c (find_saved_register): Avoid problem in current frame.
3043 (read_relative_register): Ditto.
3044 (write_register): Convert byte order on the way out.
3046 * exec.c (file_command): Add.
3047 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
3048 (xfer_memory): Common function between core_xfer_memory and
3050 (exec_xfer_memory): Use it.
3052 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
3054 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
3055 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
3056 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
3058 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
3060 Merge Intel 960 port of gdb, continuing...
3062 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
3063 symbol_file_command): Pass from_tty arg to hush 'em up.
3065 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
3066 Add magic numbers for 960 COFF format.
3068 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
3070 Merge Intel 960 port of gdb, from Intel "1.2" release.
3072 CHANGE_LOG entries from their port, which was based on
3075 Thu Sep 6 11:02:22 PDT 1990
3076 Remove temp file if download is interrupted.
3078 Wed Aug 1 09:08:33 PDT 1990
3079 Now uses binary protocol to talk to NINDY.
3080 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
3081 Times out after 5 seconds when trying to talk to NINDY.
3083 Tue May 29 12:54:49 PDT 1990
3084 Added variable baud rate (-b switch).
3085 Source code reorganization.
3087 Thu Apr 26 11:09:55 PDT 1990
3088 More cleanup of batch mode; specifically, execute "-s", "-e", and
3089 "-se" switches as soon as they are encountered on the invocation line.
3091 Fri Apr 20 13:47:15 PDT 1990
3094 Thu Apr 19 09:54:28 PDT 1990
3095 Add 'reset' command.
3097 Wed Apr 18 09:48:07 PDT 1990
3098 After opening remote tty, wait for 1 second to go by without input
3099 from it before trying to talk to NINDY (fixes problems with the
3100 Heurikon HK80/V960E).
3102 Mon Apr 4 16:33:05 PDT 1990
3103 Some output was not being suppressed in 'batch' mode.
3105 Thu Mar 22 15:31:11 PST 1990
3106 Ask user if old symbol table should be deleted when new file is
3109 Allow user to run a program downloaded before gdb960 was brought up.
3111 Correct "exec-file" help message for i80960 context.
3113 Correct bug in calculating user space address: could occasionally
3114 corrupt user program.
3116 Make sure to zero low-order bits in rip's because of bug in 960CA
3117 A-step part: could cause operation faults when "next"ing across
3120 Correct bug that made it impossible to get source line numbers for
3121 code loaded at addresses higher than 0x7fffffff.
3123 Wed Jan 10 12:43:22 PST 1990
3124 Open remote tty for exclusive use.
3126 Fri Jan 5 12:14:42 PST 1990
3127 Correct disassembly (CA manual was right after all):
3128 opcode for sysctl is 0x659
3130 Mon Oct 23 12:03:04 PDT 1989
3131 Use G960BASE and G960BIN environment variables to find 'sx' utility.
3133 Mon Oct 16 14:15:09 PDT 1989
3134 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
3136 Mon Oct 2 15:56:31 PDT 1989
3138 Added 960CA disassembly support.
3140 To simplify maintenance:
3141 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
3143 - eliminated opcode.h: incorporates tables into i960-pinsn.c
3144 - moved 960-specific routines from i960-pinsn.c to i960-md.c
3145 - made disassembly interface identical to that in gdmp960.
3149 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
3151 * target.h: Allow targets to stack. Add target_has_memory,
3152 _registers, etc. Restructure memory access and "info files"
3153 to walk the target stack.
3154 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
3155 target.c: Change tables to match target.h.
3156 * inflow.c (child_mourn_inferior): pop child_ops.
3157 (generic_mourn_inferior): Use new has_stack flag.
3158 * infptrace.c (child_xfer_memory): New memory regime.
3159 * inftarg.c (child_files_info): New "info files" regime.
3160 * remote-eb.c: New memory regime, new info files.
3161 * remote-vx.c: New memory regime, new info files. Now use
3162 separate targets for VxWorks attachment to machine, and
3163 actually running a process under VxWorks, since one has
3164 stack & execution & regs and the other doesn't.
3165 * remote.c: New memory regime, new info files.
3166 * sparc-xdep.c (fetch_core-registers): New memory regime.
3167 * target.c: New routines and support for stacked targets,
3168 new memory regime, new info files regime.
3171 Generalize section handling for an arbitrary number of sections,
3172 including use of the new BFD (binary file) library.
3173 * gdbcore.h: Add struct section_table.
3174 * exec.c (build_section_table): Iterate all sections and
3175 record what gdb needs to know about them.
3176 (exec_command): Use it.
3177 (exec_xfer_memory): Use the table.
3178 (exec_files_info): Print the table.
3179 * core.c (core_file_command, core_xfer_memory, core_files_info):
3181 * source.c (find_source_lines): Use bfd_get_mtime.
3182 * dbxread.c: Quick changes to make it compile with new BFD.
3183 * utils.c (error): Avoid using bfd_error in generic routines.
3185 * core.c (core_fetch_registers): Get from the ".regs" section of
3187 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
3189 * inferior.h (attach_flag): Export.
3190 * infcmd.c (run_command): use new target_create_inferior.
3191 * infrun.c (child_create_inferior): Don't return result.
3192 * Makefile.dist (VERSION): 3.91.4.
3194 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
3196 * breakpoint.c (bpstat_num): Handle breakpoints which have
3197 since been deleted, such as temporary breakpoints.
3198 infcmd.c (program_info): ditto.
3200 * core.c (core_file_command): Display the frame where the core
3205 * remote-vx.c (target_command): Merge in target command from
3206 targ-vx.c. A few other cleanups.
3208 * TODO, Projects: Lots more stuff to do...
3210 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
3212 Massive changes to wall off the remote-debugging interface
3213 behind a function vector. The port to handle VxWorks targets
3214 is also part of this.
3216 All files: Replace references to renamed functions,
3217 remove references to remote_debugging, remove references to
3218 have_include_file, have_core_file in favor of target_has_stack,
3219 target_has_memory, etc.
3221 * Modularize the breakpoint interface.
3222 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
3223 a breakpoint instruction.
3224 breakpoint.c: struct breakpoint's shadow_contents now sized as
3226 (insert_breakpoints): Vector to target to install breakpoints.
3227 (remove_breakpoints): Vector to target here too.
3228 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
3229 sparc-tdep.c (single_step): Use new breakpoint interface for
3230 the single-step breakpoints.
3231 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
3232 New file, contains routines to insert and remove breakpoints by
3233 reading out the old contents and later replacing them. This is
3234 how ptrace breakpoints work, and many remote systems as well.
3236 * tm-vxworks68.h: New config file, overrides a few things for
3237 Wind River's preferences.
3239 * target.h: New file, for transfer vector used to talk to the
3240 inferior (child, attached, core, exec, remote, etc). All accesses
3241 to the thing being debugged should come through these vectors.
3242 target.c: New file, routines to handle transfer vector.
3243 (various files): Add transfer vectors XXX_ops for the various
3244 targets and pseudo-targets (core files, etc) we support.
3246 * breakpoint.c (bpstat_stop_status): Further explorations of
3247 watchpoints and why things don't work all the time.
3248 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3250 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3251 the local gdbinit if it doesn't already have it.
3253 * core.c (core_ops): add and install.
3254 Allow core debugging without exec file.
3256 * dbxread.c (free_and_init_header_files): Merge two fns.
3257 (end_symtab): Free named symbol table when a new version comes in.
3258 (read_dbx_symtab): Relocate all kinds of symbols with base
3259 address. First step toward handling different text, data, bss
3261 (add_file_addr_command): Renamed add_file_command.
3262 (add_file_command): Vector to remote handler.
3263 Add "load" as an alias for "add-file" command.
3265 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3266 non-returning functions.
3268 * exec.c: Add exec_ops, and push it as a target when an exec
3271 * infcmd.c (run_command): Pass executable file name and arg list
3272 separately when starting an inferior. Permit "run" when no exec
3273 file is specified, for VxWorks.
3274 (detach_command): Move to child_detach in inftarg.c.
3276 * inftarg.c: New file. Unix-child-specific routines, and the
3277 child_ops structure.
3279 * inferior.h (registers): Export "registers" as the way for
3280 target dependent register handlers to find gdb's local copy of
3281 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3282 since it is now used by places that want wait_for_inferior to
3283 handle the grunge but want to see every trap from the inferior.
3285 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3286 Eliminate remote_debugging hooks in terminal handling.
3288 * infrun.c: Replace start_inferior with child_create_inferior.
3289 Move all the hair of Unix shells and ptrace idiosyncracies into
3290 child_create_inferior, so remote handlers don't have to deal.
3291 Remove running_in_shell. Rename stop_after_attach to
3292 stop_soon_quietly, and use it in a few other places where we want
3293 to just call wait_for_inferior and get control back on the first
3294 trap. trap_expected now never takes a value > 1.
3295 (init_wait_for_inferior): Initialize static vars when a new
3298 main.c (gdbinit): Add new hook for .gdbinit file name, let
3299 it be overridden by config files as GDBINIT_FILENAME.
3300 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3301 Both of these are used for VxWorks gdb.
3303 mcheck.c: rename include file "gmalloc.c" to avoid problems
3304 with system include file "malloc.c".
3306 param-no-tm.h: New include file, same as param.h but does not
3307 include the default "tm.h" file. This is used in files where
3308 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3310 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3312 remote-vx.c: New file, VxWorks remote debugging support. Uses
3313 RPC routines that are shared with the target system, in directory
3316 remote.c: Vectorize remote interface.
3318 source.c: Globalize source_path, and make an alias "l" for "list"
3319 since we now have the "load" command.
3321 sparc-xdep.c: Use new param-no-tm.h.
3323 symmisc.c (free_named_symtab): Add new function from Wind River.
3324 However, ifdef it out for now while we think about what it should
3327 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3329 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3330 non-Unix-children handle this with their own code in the target
3333 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3334 source and target lists. Add vx-share to default list of include
3335 directories. Add new files to src and target lists: mem-break,
3336 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3337 ${srcdir} versions of munch and createtags are used.
3339 * valops.c (find_function_addr): Split out of call_function.
3340 (call_function_by_hand): Rename call_function; this function
3341 calls functions in the target by laboriously patching the target
3342 word-by-word with the right stack, args, regs, etc.
3345 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3347 Handle AMD 29000 a bit better.
3349 * remote-eb.c (readchar): Mask received char log to make it readable.
3350 (remote_start): Pass arguments down to executing program.
3351 Make startaddr unsigned.
3352 infrun.c (start_inferior): Accept args, pass them to
3354 infcmd.c (run_command): Pass args down to start_inferior.
3356 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3357 the target object file format.
3358 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3360 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3361 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3363 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3365 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3366 * TODO: We did a few things, we have more to do though.
3368 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3369 * inflow.c (inferior_died): Clear deferred stores.
3371 * Debug problems with dummy frames and calls to the inferior.
3372 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
3373 * sparc-tdep.c (do_restore_insn): Simplify.
3374 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3375 (sparc_push_dummy_frame): Simplify and fix what we push.
3376 (sparc_pop_frame): Slightly more hair here, deciding whether
3377 we are restoring a saved PC or returning to a return address in %i7.
3378 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3380 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3381 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3382 * obstack.h (chunkfun): ditto.
3383 * defs.h (xmalloc, xrealloc): ditto
3385 * utils.c (quit): Grab the terminal from the child if necessary.
3387 * inflow.c (term_status_command): Rename to term_info, change
3390 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3391 (is_delayed_branch): Speed up.
3392 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3393 Still missing some float ops, and needs testing.
3395 * Support for input and output radixes other than base 10
3396 * defs.h (input_radix, output_radix): Declare.
3397 * expread.y (yyparse, parse_number): Handle changes of input
3398 radix, and ambiguous names-or-numbers in radixes >10.
3399 * printcmd.c (print_scalar_formatted): Print formatted hex
3400 numbers in varying column widths.
3401 * valprint.c (val_print): Use output_format to print scalar ints.
3402 (set_input_radix, set_output_radix, set_radix): Create.
3403 (set_output_radix): Set output_format from output_radix.
3404 (_initialize_valprint): add `set radix' but leave the others off.
3406 * main.c (execute_command): Let stupid questions be turned off.
3407 (_initialize_main): Handle "set stupidity", etc.
3409 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3410 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3412 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3414 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3415 bfd stuff is still screwed up, but with some manual work, it
3418 * breakpoint.c (bpstat_do_actions): Start over if a command
3419 proceeds the inferior, since the inferior will have stopped and
3420 will need to have its new stop-actions taken care of.
3422 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3423 compiler fits, simplify it.
3425 * gdb.texinfo (directory command): Doc new dir command.
3426 source.c (directory_command): "dir" now puts things on the front
3427 of the path, moves dups up front, and handles multiple names
3428 on the command line, inserting each one in order. It also
3429 blows away cached line and full_filename info.
3431 * stack.c (backtrace_command): Skip "more stack frames follow"
3434 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3435 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3436 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3437 The only odd one was Gould NP1, which had defined vprintf to
3440 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3441 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3442 variable, inspect_it.
3443 valprint.c (print_string, val_print): Use the global inspect_it
3444 to indicate whether to print in Epoch style or normal style.
3446 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3448 * printcmd.c (call_command): add an alias for the "print" command
3449 which runs expressions and doesn't print the result if void.
3450 (print_command_1): implement it.
3452 * command.c: Remove #if 0'd code. Initialize all the fields
3453 in add_cmd (). Rename do_nothing_command to
3454 not_just_help_class_command, and make it externally visible.
3455 command.h: add user_commands to struct.
3456 * main.c (define_command): Don't overload c->function with a char
3457 string as well as a function pointer.
3459 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3460 calling convention of value_struct_elt () that got dropped in
3463 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3464 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3466 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3468 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3469 until a good time (e.g. when we are about to run the child),
3470 saving ptrace calls.
3471 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3472 * tm-sparc.h: define DO_DEFERRED_STORES.
3474 * sparc-xdep.c (store_inferior_registers): when storing float
3475 registers, don't store stack regs too. When storing the SP,
3476 however, DO store the stack regs too. This fixes a bug in which
3477 the dummy frame is not recognized when a call_function finishes,
3478 because its frame pointer (in the stack regs) was never
3480 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3481 even though we don't know how to read them from an inferior.
3482 valops.c (call_function): Comment about storing SP.
3484 * infrun.c (save_inferior_status): Save away the original bpstat
3485 chain so it can be restored later. Install the copied version for
3486 use by whoever saved the status. It will be blow away by
3487 restore_inferior_status, and the original chain restored. This is
3488 important for people who have pointers into the original.
3490 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3491 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3492 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3495 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3497 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3498 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3499 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3501 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3503 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3504 Store the baseclasses in a type struct starting from array element
3505 0 rather than from the unusual array element 1.
3507 dbxread.c: the above.
3508 (virtual_context): Add
3509 Read new debug information about which virtual function table
3510 a virtual function is from, and store it in fn_field.fcontext.
3512 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3513 TYPE_FN_FIELD_STATIC_P.
3515 symtab.c: the above.
3516 valops.c: the above. Handle pointer casts of object *'s.
3517 (search_struct_method): Add.
3518 (value_struct_elt): First arg is now a pointer to a value, and is
3521 valprint.c: the above.
3522 values.c (value_virtual_fn_field): Add type arg. Handle
3523 offsetting to the proper object when calling virtual fns.
3525 (baseclass_addr): Add valuep arg.
3527 * README: Document the current state of BFD config (missing).
3528 * TODO, ChangeLog, Makefile.dist: Roll version.
3529 * WHATS.NEW: Add summary of changes since 3.5.
3531 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3533 * dbxread.c (read_struct_type): Clear bit vectors whenever
3535 symtab.c (B_CLRALL): define.
3537 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3538 using == rather than =. Huh... This fixes the dreaded problem
3539 wherein builtin_type_int becomes TYPE_CODE_FLT.
3541 * core.c (info_files): Show the inferior pid.
3543 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3544 already knows how to look in the source directory.
3546 * Remove psymtab hair from many places. Remove duplicated code
3547 for searching symbol tables. Hide psymtabs from most places.
3548 Make it fast to get from a psymtab to its symtab.
3550 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3551 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3552 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3553 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3554 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3555 new symtab completely. New psymtabs get symtab pointer
3556 initialized to zero. Remove MI warning printf.
3557 symtab.h: Comments. Add psymtab to symtab pointer.
3558 (PSYMTAB_TO_SYMTAB): New macro.
3559 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3560 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3562 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3564 (print_frame_info): Avoid special-casing symbols that have not yet
3567 * source.c (open_source_file): Quick path if we have already
3568 located the source file by its full name.
3570 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3571 find_pc_psymtab. When a name is found in the misc function
3572 vector, search the symbol table for its mangled name, not the
3573 name that the user typed.
3575 * bfd.h: Fix missing comment terminators, make #endifs match.
3577 * valarith.c (value_less): Handle unsigned int comparisons.
3578 Add FIXME about pointer compares, which assume host and target
3579 pointers are the same.
3581 * command.c (do_nothing_command): lint
3582 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3583 fix comments on debug symbol format for visibility. Actually set
3584 visibility of symbols.
3585 main.c (echo_command): lint; use <readline/history.h>.
3586 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3587 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3588 pointing past end of allocated memory; saber complains.
3589 obstack.h: Declare the external functions that we use.
3590 valarith.h: use <string.h>
3591 solib.c (solib_add): lint.
3593 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3595 * main.c (initialize_main): Default info_verbose to off, now that
3596 symbol reading is fast.
3597 (quit_command): Avoid clobbering exec_bfd while quitting.
3599 * Initial BFD (binary file diddling library) merger:
3600 coffread.c: Change AOUTHDR to struct exe_hdr.
3602 core.c: initialize initialized data at compile time.
3603 (core_file_command): Move from coredep.c, convert to bfd.
3604 (xfer_core_file): Convert to bfd.
3605 exec.c (exec_file_command): use bfd routines.
3607 mips-tdep.c: Remove exec_file_command and friends.
3610 * coredep.c: (fetch_core_registers) Convert core_file_command to
3611 fetch_core_registers.
3612 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3614 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3615 (my_bfd_read): More bogosity, which I don't think we call.
3616 (program_name): Remove this atrocity asap!
3618 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3621 values.c: allocate_repeat_value was not clearing the
3622 optimized_out field.
3623 (value_static_field): minor stylistic fix (wrong macro was used).
3624 valops.c (value_struct_elt_for_address): didn't work for C++
3627 * signame.c (_initialize_signame): Initialize signal names once.
3629 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3630 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3631 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3633 * remote-eb.c: Support user-settable baud rates on the serial port.
3635 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3637 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3639 * tconfig/sun3os4: Remove warning about native assembler,
3640 since it also occurs in the xconfig file.
3642 * findvar.c (registers): Allocate some slop after `registers'
3643 to prevent stray accesses from trashing the next variable.
3645 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3646 on the sun-3, by changing the #ifdef from `sun3' (which is not
3647 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3648 vars, which happened to follow `registers' in the executable.
3650 * readline/history.c (history_search): Heed gcc-2's advice
3651 and parenthesize && inside ||).
3653 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3654 tm-29k.c: Insert FSF copyright headers.
3656 * remote-eb.c: Better comments.
3658 * Makefile.dist: Update to 3.91.6.
3659 * TODO: note PREPARE_TO_STORE problem.
3661 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3663 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3665 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3667 * infrun.c (wait_for_inferior, at end): Don't set up
3668 prev_* if the inferior no longer exists.
3670 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3671 CANNOT_EXECUTE_STACK.
3672 valops.c (call_function): Use it.
3674 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3676 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3677 infrun.c (wait_for_inferior, 2 places): Use it.
3679 * values.c (value_being_returned): Only use
3680 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3682 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3683 right thing for remote-eb.c.
3685 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3686 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3688 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3689 (FRAME_FIND_SAVED_REGS).
3691 * findvar.c ({fetch,store}_registers): Check for
3692 REMOTE_{FETCH_STORE}_REGISTER macro.
3694 * findvar.c (get_saved_register): Add argument lval and
3695 change meaning of argument addr.
3696 findvar.c: Change calls to get_saved_register to reflect
3697 new calling convention.
3698 valops.c (value_assign): Use get_saved_register instead of
3699 find_saved_register.
3701 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3703 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3704 an (uninitialized) pointer to one. Use "&" when passing it
3707 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3709 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3712 * coffread.c (symbol_file_command): Put semicolon after
3714 Put safe_to_init_tdesc_context in #if defined (TDESC).
3715 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3716 coffread.c: #include <sys/stat.h>.
3717 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3718 Add missing ')' in check for "lc%" and friends. Remove
3720 Declare read_one_sym() at top of file.
3721 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3722 MC68WRMAGIC can have the same value without causing a duplicate
3725 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3727 * Allow a Makefile to be built without building the
3728 tm and xm file links that screw up builds in subdirectories.
3729 This is done with `config.gdb none', then you can do things
3730 like `make gdb.tar.Z'.
3731 * tconfig/none: Config file for no target system
3732 * xconfig/none: Config file for no host system
3733 * config.gdb: If no TM or XM files are called out by the
3734 host or target file, don't make links for them.
3736 * cplus-dem.c: Add documentation.
3738 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3739 simple error, so the user's gdb doesn't crash due to some object
3740 file problem (e.g. somebody is rebuilding the file out from under
3743 * printcmd.c (print_address_symbolic): demangle the symbol.
3745 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3746 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3747 (alldeps.mak): sort and uniq all results from this; duplicates
3748 hose gdb.tar.Z link building. Remove RCS files from
3749 tconfig and xconfig. Add config files for sun386. Add
3750 a few odd files to OTHERS and HFILES.
3752 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3754 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3755 Roll version number to 3.91.5. Make lint work in bindir.
3757 * README: Document cross-debugging and new file structure.
3759 * blockframe.c: Lint. Include "value.h" to declare read_register.
3760 (find_pc_partial_function): remove duplicate line.
3762 * command.h: Lint. Declare error_no_arg and dont_repeat.
3764 * tm-news.h: Remove inadvertently duplicated stuff.
3766 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3767 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3769 * config.gdb: Allow `config.gdb host target' form. Clean
3770 up previous change that printed bogus messages when you just said
3773 * core.c: #include "command.h" for lint.
3776 * main.c: Remove some casts of enums. Lint.
3783 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3785 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3786 read it from memory. This will allow us to save ptrace calls
3787 eventually. Changed caller single_step too.
3789 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3790 that we aren't going to use, saving many ptrace calls, especially
3791 when watchpointing or single stepping. Use some #define's for
3793 (store_inferior_registers): Ditto.
3794 (core_file_command): Use some #define's for constants.
3796 * tm-sparc.h: Add #define's for some register numbers, so we
3797 can eliminate the use of random constants in sparc-xdep.c.
3799 * stack.c (frame_command, print_frame_info, up_command,
3800 down_command) Remove frame_changed, since it
3801 causes a bug and doesn't seem to do anything useful. In some
3802 places it was used as a flag, in others as a stack level (?).
3804 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3805 default is to use the portable (vprintf) version rather than the
3807 * xm-news.h (MISSING_VPRINTF): Add.
3809 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3811 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3813 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3814 about linking debugged programs -Bstatic in the sun?os4 config
3815 files in tconfig and xconfig subdirectories.
3817 * main.c (main): Remove unreached exit(0) now that we exit
3820 * Create TODO file for online bug list. There are too many
3821 "little" bugs to keep track of on paper.
3823 * Change Projects file to refer to bug-gdb@cygnus.com
3824 rather than kingdon@ai.
3826 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3828 * Makefile.dist (VERSION): 3.91.4 now.
3830 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3831 (condense_misc_bunches): Add sanity check that misc_count is
3832 the same as the number of symbols in the bunch.
3834 * coffread.c: rename init_misc_bunches. Pass an argument
3835 to condense_misc_bunches (a zero).
3837 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3838 every time we are called; don't rely on our caller to do it.
3839 (add_file): Remove call to init_misc_bunches.
3841 * mipsread.c: Only warn, don't error, if unknown symbol types.
3842 This keeps an old gdb from falling on its face if it sees newly
3843 extended symbol info. Rename init_misc_bunches.
3845 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3847 * Merge in changes from Per Bothner for DECstations and other
3848 MIPS stuff. The rest is Bothner speaking:
3850 The next message is a merger of Alessando Forin's mips port with
3851 mine. I've tried to use my good if biased judgment to get
3852 the best of both. It *does* need testing.
3854 Some of the changes are general, *not* mips-specific.
3857 Didn't believe in little-endian bit order.
3858 There are still inconsistencies about whether flags
3859 like BITS_BIG_ENDIAN are integer (#if ...) or
3860 boolean (#ifdef ...). I tried to paper over them.
3862 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3863 Moved some misc_function code that was common to
3864 {dbx,coff,mips}read.c to symtab.c.
3865 In the process, I think I cleaned things up a bit.
3866 At the same time, moved obsavestring and obconcat to symtab.c.
3869 Removed obsolete condense_addl_misc_bunches (use
3870 condense_misc_bunches(1) instead).
3873 Needed to include <sys/dir>, at least on DECstations.
3875 valops.c, mips-tdep.c, tm-mips.h:
3876 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3877 conventions (when STACK_ALIGN is insufficient).
3878 Needed on mips, where doubles need 8-byte alignment,
3879 but ints only need 4.
3882 Removed cruft that was not being used.
3883 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3886 Print $ before register-names (I think that makes things a little
3888 Never print two instructions, even if one delays.
3889 Removed hex-disassemble set_cmd. (This is not mips-specific,
3890 so I think the argument is whether it is generally worthwhile or not.
3891 I'm inclined to think not, given how easy it is to
3892 convert between radixes in gdb.)
3895 This is basically Alessando's code.
3896 It doesn't use obstacks; I changed it to use obstacks
3897 in a few minor places where using malloc causes a
3898 memory leak. (Probably, more places could/should be changed.)
3899 I added record_misc_function where it was missing.
3900 In symbol_file_command and add_file_command, I tried
3901 to make the code consistent with more recent versions.
3902 Minor sylistic changes in parse_procedure.
3903 Make a .gdbinfo. psuedo-symbol point back to the real
3904 procedure symbol (using the isym field).
3907 This is basically from my port, but with a lot of details
3908 and a number of routines merged in from Alessando's version.
3909 I basically used my code "raw" backtrace (use heuristics
3910 from the actual code, rather than symbol table info) - though
3911 the idea is Alessandro's. I feel my code is a little cleaner
3912 here, particularly in being a little more flexible, such as being
3913 able to handle gcc-produced code (which it now can).
3914 It also doesn't do frame caching (which is not useful
3915 more recent gdb versions).
3916 I also used my code for push_/pop_dummy, more or less.
3917 I tried to incorporate AF's code for testing sigtramp
3918 while backtracing; I probably got it wrong.
3919 Added mips_print_register, which tries to scrunch as much
3920 information as possible on a screen...
3921 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3922 under mips-pinsn.c), I don't see anything mips-specific here,
3923 and I don't see it being all that useful anyway.
3926 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3927 Use more register names (rather than hard-cases numbers).
3929 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3931 * Hack up 3.90.11 changes:
3933 * Makefile.dist (depend): parameterize $(GCC).
3934 Add solib.c and solib.o.
3935 (readline): Fix vpath for both absolute or relative SRCDIR.
3937 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3938 Also, let the part I didn't understand at least compile so
3939 I can test the rest. FIXME.
3941 * dbxread.c: Fix thinko using strcmp.
3942 (init_psymbol_list): declare static.
3943 (partial_symbol_file_open): Comment cleanups better, avoid
3944 cleaning up the string table since the caller will do that.
3945 Move the stat for mod time into symbol_file_command, temporarily.
3946 (There should be a mod time for each symbol file, eventually,
3947 to control its rereading. FIXME.)
3949 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3950 SunOS, which gives error for shared libs otherwise. (From
3951 Schaefer, probably FIXME needs work for portability.)
3953 * solib.c: Move #include "param.h" to work.
3954 Lowercase all the Uppercase Letters In the Messages.
3955 (find_solib): Clean up inferior_so_name for debug printouts.
3956 Allow no argument, to mean all shared libraries.
3958 * symmisc.c: include param.h to get CLEAR_SOLIB.
3960 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3962 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
3963 to 3.90.11. ChangeLog entries below are from this.
3965 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3969 * Makefile.dist (HFILES): Add tm-sunos.h.
3971 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3975 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
3977 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
3979 * sparc-opcode.h Added single-operand version of rett.
3981 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3983 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
3984 Put parens around gcc_p in expansion.
3986 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3988 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
3990 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3992 * Changes for Sun shared libraries:
3993 blockframe.c (find_pc_partial_function): If a non-text symbol
3994 is found, set *address = pc - FUNCTION_START_OFFSET.
3995 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
3996 Disable breakpoints instead of giving an error.
3997 source.c (select_source_symtab): Initialize cs_pst.
3998 symmisc.c: Call CLEAR_SOLIB if defined.
3999 symtab.h: Make text{low,high} CORE_ADDR not int.
4000 (psymtab): New field addr.
4002 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
4003 (record_misc_function): Give correct type for N_DATA symbols.
4004 (condense_misc_bunches): do "misc_function_count = j" regardless
4006 Take code which is shared between symbol_file_command and
4007 add_file_command and put it into partial_symbol_file_{open,read}.
4008 Split add_file_command into add_file_command and add_file.
4009 Make psymtab_to_symtab read in the string table if the file
4011 Two new parameters to read_dbx_symtab and start_psymtab.
4012 tm-sunos.h: New file.
4014 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4016 * infcmd.c: Change cont_command to continue_command and "cont"
4019 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4021 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
4023 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
4025 * values.c (USE_STRUCT_CONVENTION): Check for structures of
4026 size 1,2,4,8 rather than size < 8.
4028 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
4029 as necessary, not just once.
4031 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
4033 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4035 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
4037 * tm-news.h: Add CALL_DUMMY_*.
4039 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
4041 * config.gdb: In list_host, list_target, use ${i}, not $i.
4043 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4045 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
4047 * sparc-opcode.h: Change all store floating-point state register
4048 instructions to have the right match & lose fields.
4050 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4052 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
4054 config.gdb: If srcdir != ., create readline directory and
4055 copy a makefile into it.
4057 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
4058 consistency with POSIX.
4060 * breakpoint.c (bpstat_stop_status): Disable watchpoint
4061 when we exit its exp_valid_block.
4063 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
4065 * Makefile.dist: Bump version to 3.91.3.
4067 * Clean up handling of breakpoint commands (somewhat).
4068 Prompted by Tiemann bug report "cont 10" doesn't work any more.
4070 inferior.h: Add breakpoint_proceeded to inferior status struct
4071 and globals; save it and restore it.
4072 (clear_breakpoint_commands): Cleanup, remove old #define.
4074 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
4075 (save_inferior_status, restore_inferior_status): handle it also.
4076 (proceed): Remove earlier code that set breakpoint_proceeded.
4077 It is now set only in clear_proceed_status.
4078 (clear_proceed_status): Cleanup, use bpstat_clear rather
4079 than clear_breakpoint_commands. No callers need the stop_bpstat
4080 between clear_proceed_status and proceed.
4082 infcmd.c: Add breakpoint_proceeded definition and comment.
4083 (cont_command, jump_command, signal_command): Move call to
4084 clear_proceed_status right next to call to proceed.
4086 breakpoint.c (bpstat_do_actions): Avoid clobbering our
4087 caller's argument while running down the chain of breakpoints.
4088 Use new variable "breakpoint_proceeded" to determine when
4089 a command that it executes moves the inferior past the
4091 (bpstat_clear): Handle NULL argument.
4092 (bpstat_clear_actions): Avoid useless call to
4093 breakpoint_auto_delete.
4094 (delete_breakpoint): Clean up bpstat's that are pointing to
4095 the deleted breakpoint from the stop_bpstat chain.
4096 (breakpoint_auto_delete): Simplify.
4098 * Clean up handling of EOF, error on stdin, etc. This was
4099 prompted by a network problem that caused gdb to go into an
4100 infinite loop filling up its malloc'd memory.
4102 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
4103 not clear_breakpoints_commands, which is now gone.
4104 (main): If command_loop returns (e.g. from EOF on stdin), do
4105 a quit_command (looping back to command_loop if quit_command
4106 doesn't really quit).
4107 (command_loop): check result from command_line_input and
4108 exit if it returns NULL, rather than passing the NULL to
4110 (gdb_readline): Free malloc'd result space before returning
4113 * utils.c (query): Handle C-d to mean "yes", just as if the
4114 input was not a terminal. Also avoid infinite loop if EOF
4115 occurs in mid-input-line before newline. This allows
4116 query to be used at EOF on stdin with reasonable results.
4118 * infrun.c (proceed): Set breakpoint_proceeded.
4120 * values.c (value_as_long): Avoid infinite recursion for enums.
4121 (_initialize_values): Fix typo in help msg (kingdon).
4123 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
4124 RL_LIB for linking. This allows -lreadline for linking
4125 and nothing for dependencies, once readline is a real library.
4127 * config.gdb: Jim Kingdon: give useful error message if the
4128 host or target type is not recognized.
4130 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
4131 it just defines it. Dumb, but deal with it.
4133 * Jim Kingdon suggests:
4134 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
4136 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
4138 * Makefile.dist (VERSION): Bump version # to 3.91.2.
4140 * Clean up Bothner's changes.
4142 * blockframe.c (clear_pc_function_cache): New function.
4143 * blockframe.c: remake cache_pc_function_* static.
4144 * dbxread.c (symbol_file_command): remove references to
4145 cache_pc_function_* variables.
4146 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
4147 * printcmd.c: Avoid kludging a global variable (addressprint)
4148 to avoid printing the address of a string twice. Instead,
4149 pass the format letter 's' down low enough that it can be seen
4150 to avoid this problem.
4151 (print_formatted): Pass format arg to value_print.
4152 (restore_addressprint): Remove function.
4153 (do_examine): Avoid hacking addressprint, cleanups and such.
4154 (print_frame_args): Add a comment to a Bothner change.
4155 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
4156 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
4157 to wipe out the values cached in blockframe.c.
4158 * symtab.c (find_method): Add comment saying how big you must
4159 allocate to be "big enough". Per being terse again.
4160 * valprint.c (val_print): Handle format letter "s" to print
4161 strings without addresses. Add comment to vtbl printing code
4162 which casts with wild abandon. Rearrange reference-printing
4164 @0xaddr: value (print w/addressprint)
4165 value (print w/~addressprint)
4166 @0xaddr (parameter lists w/addressprint)
4167 or nothing (parameter lists w/o addressprint)
4169 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
4171 * Merge more changes from Per Bothner:
4173 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
4174 annoying) that I tried to improve it. Here are my suggestions.
4176 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
4179 Do automatic de-reference when taking the address of a reference.
4181 Don't deref_ref when printing parameter lists.
4183 More attempts at treating refernences properly.
4185 In val_print, if deref_ref==0, don't print dangling " = ".
4187 Add COERCE_REF macro, which de-references an REF.
4189 * Merge changes from Per Bothner:
4191 * Fixed (Sony news)-specific configuration problems.
4192 * Fixed other problems with using vanilla pcc and libc (enum problems;
4193 assumption that vsprintf exists).
4194 * Some major speed-ups (finc_pc_partial_function now caches a match;
4195 parsing avoids duplicate symbol_lookup calls).
4196 * Changed handling of baseclasses (no longer use baseclasses field
4197 of struct type, use the first n_baseclasses fields instead).
4198 * Various minor changes/fixes, most C++-related.
4201 Cache the most previous match from find_pc_partial_function.
4202 (Save both low and high ends of matching function's pc range.)
4203 This speeds up the loop of infrun.c:wait_for_inferior quite
4204 a bit, and makes step/next commands much zippier.
4206 Added an enum->int cast (otherwise, some compilers barf).
4208 No longer set baseclass offset to 0, since multiple
4209 inheritance now mostly works.
4210 Added a number of casts, to shut up compiler warnings
4211 (after stabs where made enums, not ints).
4212 When discarding a symbol table (in symbol_file_command),
4213 must clear the cache introduced in blockframe.c.
4214 Don't convert $vtbl_ptr_type to vtbl any more.
4215 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
4216 Mask off sign bit emitted by g++ for virtual table offset.
4217 Set voffset to -1 (not 1) for static member functions.
4219 Changed parsing/lexing of names to avoid doing symbol lookup twice
4220 (once when lexing to determine symbol class, once for real).
4221 Now only call symbol_lookup once. Fields of 'this' win especially big.
4223 Subpress printing addr twice in the case of 'x/s addr'.
4225 lookup_basetype_type is no longer used.
4226 Add find_methods as recursive helper function to decode_line_1.
4227 This allows multiple inheritance to work.
4228 Also, once one or more matches has been found, do not look in
4229 base-classes. (Baseclass methods would be overridden, anyway.)
4231 Removed baseclasses array in struct type.
4232 Instead of using baseclasses[i], use fields[i-1].
4233 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
4234 Changed sign convention of voffset (previous was inconsistent).
4236 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4238 Used to assume existence of vsprintf. Re-written to not need it
4239 if HAVE_VPRINTF is undefined.
4241 typecmp was too pessimistic. Made it less so.
4243 Don't print space after address.
4244 If vtable points to a misc symbol (with 0 offset), print it,
4245 since that indicates the actual class of the object.
4246 Changed ype_print_derivation_info to use new inheritance
4247 scheme (without baseclasses vector).
4249 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4250 Also, changes needed because TYPE_BASECLASSES were removed.
4252 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4254 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4257 If there is no path set, and the symbols don't indicate what directory
4258 a file was compiled in, look in the current directory. But either
4259 a path or a known compilation directory will prevent this.
4262 Three independent bug fixes:
4263 * Remove the #if 0 block that breaks some stuff.
4264 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4265 adapt gdb to either SunOS 4.0.* or 4.1.
4266 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4269 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4272 (type_print) Demangle the name being printed.
4273 (type_print_base) Handle botched demangling without coredump (tiemann).
4276 (check_stub_method): Document routine.
4277 (tiemann) fix bug for no-arg functions
4278 Avoid clobbering beyond end of malloc'd storage.
4279 Terminate the argument list properly.
4281 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4283 * Changes merged by John Gilmore:
4286 In breakpoint_1, use new print_address_symbolic instead
4287 of find_pc_partial_function. (This forces use of assembler-level
4288 addresses, and avoids misleading non-mangled source-level names.)
4290 Generalize ansi argument such that -1 means skip arglist totally.
4291 Removed global variable print_ansi_qualifiers (which made
4292 code non-reentrant), in favor of extra explicit arguments
4293 to internal routines.
4295 Add new helper function print_address_symbolic.
4296 Use find_pc_misc_function instead of find_pc_partial_function
4297 (since we want assembler-level symbols here).
4299 Print unknown function as just "f (...)", not "f (...) (...)".
4300 Use new fputs_demangled explicitly.
4302 Fixed a typing violation (problem: value.h cannot be imported
4303 without renaming many variable in this file).
4304 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4305 decode_line_1: Moved forward some never-reached code.
4306 Made decode_line_2 skip function prologues correctly.
4308 fputs_filtered should not demangle by default.
4309 Add new fputs_demangled to demangle on demand..
4311 Change value_struct_elt to use value_primitive_field (using recursive
4312 utility function search_struct_field). This allows foo.bar to work
4313 for multiple inheritance (so far only for data fields).
4314 Change check_field in the same way (recursive helper function
4315 to support multiple inheritance).
4316 (Note: there are more of these problems that I haven't fixed.
4317 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4318 value_of_this: 'this' symbol name is now just "this", note "$this".
4320 Don't print static members.
4321 Avoid printing "members of <type>" if there are none.
4322 Simplified type_print_derivation_info by merging duplicate code.
4323 Remove useless blank lines in type_print_base (ptype command).
4325 Added declaration of new routine value_primitive_field.
4327 Added value_primitive_field which is generalized version of
4328 value_field that can handle multiple inheritance (non-zero offsets etc).
4329 Re-implemented value_field to call value_primitive_field.
4331 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
4333 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4334 delete the whole environment. Karl Berry reported the bug.
4335 * source.c - fix openp to avoid //'s in filenames, which
4336 trigger an Emacs bug causing it to not be able to find files
4337 when running gdb in a window.
4338 * dbxread.c - zap the #if 0 that botches the add-file code.
4339 It seems to work a lot better without all the code commented out.
4341 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
4343 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
4346 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
4348 * Makefile - added a ${CFLAGS} to a couple of entries,
4349 added remote-sa.sparc.c
4350 * added remote.sa-sparc.c, a modification of remote.c
4351 which conducts a dialog directly with the SparcStation prom.
4352 * breakpoint.c, infrun.c, sparcdep.c added
4353 remote_insert_breakpoint(), and remote_remove_breakpoint()
4354 to breakpoint.c instead of directly writing breakpoint instructions.
4355 * sparcdep.c on remote_debugging,there is no need
4356 to remove signle step breakpoint instructions.
4357 * main.c added "-epoch" flag and "int epoch_interface" to main.c
4359 * printcmd.c - epoch interface sends lisp expressions to open up
4360 epoch windows on inspection.
4361 * valprint.c - added arrayprint, and addressprint and made adding
4362 format controls easier
4363 * wait.h added a couple of undef's because we were getting
4364 complaints about WSTOPSIG and WTERMSIG begin redefined.
4367 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
4369 * symtab.c (decode_line_1): Add support for handling method stubs
4370 in the type information.
4372 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
4374 * values.c (baseclass_addr): Run loop from INDEX+1 to
4375 N_BASECLASSES; otherwise, we can still get into a loop.
4376 @@ This should be restructured to use a cleaner search strategy.
4378 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
4380 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
4381 abbreviation "Tt" for tags which have the same name as their
4384 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
4386 * symtab.c (list_symbols): add ability to set breakpoints on all
4387 the functions which match a particular regular expression.
4389 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
4391 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
4392 should print ANSI qualifiers (such as `const' and `volatile').
4393 All callers changed to call with ANSI == 1, except from
4394 `check_method_stub', which uses old-style syntax.
4396 * symseg.h (struct fn_field): Remove unneccessary `args' field.
4397 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
4399 * values.c (check_stub_method): New function.
4401 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
4403 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
4404 * valprint (type_print_base): Ditto.
4406 * symtab.c (gdb_mangle_typename): New function.
4408 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
4410 * breakpoint.c (catch_command): New function. Provides a
4411 mechanism to set breakpoints based on catch clauses.
4412 (disable_catch): Similar, but disables breakpoints on catch
4414 (delete_catch): Similar, but deleted breakpoints on catch clauses.
4416 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
4418 * blockframe.c (blockvector_for_pc): New function.
4419 * blockframe.c (block_for_pc): Changed to call
4420 `blockvector_for_pc' and get the block itself.
4422 * stack.c (catch_info): New function. Prints info about
4423 exceptions which can be caught in the current frame.
4424 * stack.c (print_frame_label_vars): New function. Similar to
4425 `print_frame_local_vars'.
4426 * stack.c (print_block_frame_labels): Prints out labels that are
4427 defined in this frame. These labels are exceptions that can be
4430 * dbxread.c: Updated to handle N_CATCH symtab types.
4432 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
4434 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
4435 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
4436 when printing the type.
4438 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
4440 * valprint.c (val_print): Use `baseclass_addr' to access the
4441 baseclasses pointed to via the derived class object at VALADDR.
4443 * values.c (baseclass_addr): New function. Casts derived pointers
4444 to baseclass pointers taking virtual baseclasses and multiple
4445 inheritance into account.
4447 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4451 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4453 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
4454 exp_valid_block field correctly.
4456 * infrun.c (wait_for_inferior): When checking "don't even think
4457 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
4458 also check step_resume_breakpoint.
4459 Insert breakpoints and continue (not step) if
4460 step_resume_break_address != NULL, even if another_trap.
4461 If trap_expected and we enter sigtramp, then set up a
4463 If trap_expected is set when we hit the step_resume_break,
4465 When calling resume and trap_expected says tell resume to step
4466 (2 places), also check step_resume_break_address.
4468 * infrun.c (wait_for_inferior): Don't set
4469 prev_{pc,sp,func_{start,name}} before calling wait ().
4470 Do set them after exiting loop.
4471 Move their declarations outside functions.
4472 (start_inferior): Initialize them.
4474 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4476 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
4477 Restore old code which distinguishes between trap_expected and
4478 running_in_shell, just make the latter take any non-TRAP signal,
4481 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
4483 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
4484 xconfig/3b1 (CC,PINSN_CC): Define.
4486 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.
4490 * breakpoint.c (bpstat_stop_status),
4491 infrun.c (wait_for_inferior) [SHIFT_INST_REGS]: New code.
4493 * param.h, tm-88k.h: Define ADDR_BITS_*.
4494 infcmd.c (jump_command, read_pc), infrun.c (wait_for_inferior),
4495 printcmd.c (do_one_display): Use them.
