13 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
15 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
16 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
17 breakpoint.c, main.c: lint.
19 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
21 Install new configuration scheme for GDB and friends.
23 * config.sub: Translate ordinary names to three-part names.
24 * configure: Use three-part names internally.
25 * configure.in: Translate three-part names to filenames.
27 * README, WHATS.NEW: Update for gdb-4.0.
28 * Makefile.in: Roll VERSION to 3.99.
30 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
32 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
33 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
34 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
35 to single structures rather than arrays; when passing
36 their address, use &. This avoids trouble with bdead compilers.
37 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
38 instead. This avoids portability headaches.
39 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
41 * source.c (open_source_file): Avoid ANSI const bdeath by
42 skipping declaration and then casting result value.
43 * tm-hp300bsd.h: Clarify comment.
44 * utils.c (strstr): Result is const char *; ANSI bdeath.
45 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
46 since system include file defines it differently from "defs.h",
47 though the two are equivalent for our purposes.
48 * tconfig/hp300bsd: Add m68k-tdep.o.
50 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
52 * tconfig/sun*4: Remove warnings about system assembler.
54 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
56 * mcheck.c: Avoid warning about undeclared abort fn.
57 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
58 it causes recursive calls to error() when used in cleanups.
59 To do so requires that we make it a function, so we do.
60 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
61 * utils.c (do_cleanups): Remove the current cleanup from the
62 chain *before* calling it, in case error() is called from it.
63 The result won't be pretty, but won't be an infinite loop either.
65 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
67 * dbxread.c (read_struct_type): Grok anon structs for C++.
68 (vb_name, vptr_name): Null terminate these strings.
70 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
72 Minor bug fixes from BSD Net2 gdb:
74 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
75 returns 0, there is no previous frame.
76 * breakpoint.c (commands_command): If !from_tty, don't call
77 input_from_terminal_p().
78 * dbxread.c (record_misc_function): Speed up slightly.
79 (compare_psymbols): Ditto.
80 * infcmd.c (do_registers_info): Take a second argument to
81 determine whether to print float registers. "info registers"
82 does not do so anymore. "info all-registers" does, now.
83 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
85 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
86 * inflow.c (initialize_inflow): Set tflags_ours correctly.
90 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
91 executing_breakpoint_commands if we are interrupted by error.
92 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
93 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
94 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
95 catch_errors() so we can setup the frame regardless of whether
97 * ieee-float.c (double_to_ieee_extended): Get exponent from
98 right place in little-endian systems. From John Carey.
100 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
102 * main.c: Remove unused terminating_signals and catch_termination().
103 (long_options): Terminate with a zero element.
104 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
105 (gdb_readline): Make call-compatible with readline.
106 (init_signals): Improve comments re vfork vs. signal.
108 * utils.c (prompt_for_continue): Use new gdb_readline().
109 If we prompt for continuation, we don't let CR repeat the previous
110 command, once we get back to a prompt. It's too easy to keep
111 hitting CR, expecting "--more--" prompts, and have some long
112 command start repeating on you.
114 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
116 * blockframe.c (frameless_look_for_prologue): Speed up by
117 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
118 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
119 Define two variants, one faster.
120 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
121 and return zero, rather than giving an error.
122 (setup_arbitrary_frame): Initialize the PC in the new frame.
123 (skip_prologue): Add a second arg saying whether we're just
124 checking for a frameless function or not.
126 * core.c (core_open, core_close, core_xfer_memory): Move
127 section table pointers and bfd* into the target_ops.
128 (core_open): Allow errors in shared lib reading, etc.
129 (core_files_info): Describe shared library sections.
131 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
132 exec_files_info, set_section_command): Move section table
133 pointers and bfd* into the target_ops.
134 (add_to_section_table): Add BFD to section table.
136 * target.c (target_xfer_memory, target_info): Pass target to
137 xfer_memory and target_info functions.
140 * gdbcore.h: Move struct section_table.
141 * target.h: New home of struct section_table.
143 * solib.c (solib_add): New argument is the target_ops whose
144 section list is to be added to, if any. Reallocate the
145 sections in that target to add any that come from shared libs.
146 (throughout) so_sections renamed to sections.
147 (solib_xfer_memory): Deleted.
148 * tm-sunos.h (SOLIB_ADD): Add target argument.
149 (SOLIB_XFER_MEMORY): Delete.
151 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
152 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
153 from target_ops. It's the same on all targets. Add two section
154 pointers to target_ops.
156 * stack.c (find_relative_frame): Dump ancient algorithm for
157 "down", just use handy "next" pointers.
158 (frame_command): Don't error if there is no stack; let user
161 * inflow.c (new_tty_prefork, new_tty): New prefork routine
162 modifies static state in the parent process; new_tty itself
163 runs in the child and modifies the child's file descriptors
164 to match the saved static state.
165 * infrun.c (child_create_inferior): Call new_tty_prefork,
168 * infptrace.c (child_xfer_memory): Add ignored target arg.
169 * remote-eb.c (eb_xfer_inferior_memory): ''
170 * remote-nindy.c (nindy_xfer_inferior_memory): ''
171 * remote-vx.c (vx_xfer_memory): ''
172 * remote.c (remote_xfer_memory): ''. Rename from
173 remote_xfer_inferior_memory.
175 * main.c (main): Only try to attach "corefile" argument if
176 it starts with a digit.
178 * symfile.c (symbol_reloading): New "set/show" variable.
179 (symbol_file_add): Shorten message about symbol reading.
180 (add_symbol_file_command): Merge with add_syms_addr_command,
181 since this should work on all targets now.
182 (stop_whining): Default to zero, to shut up complaints
183 about bad symbol tables on many systems.
184 (free_named_symtabs): Just exit unless symbol_reloading.
186 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
187 and add comment explaining shared library screw.
189 * source.c: #if defined => #ifdef.
191 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
193 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
195 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
197 * doc/rdl-apps.texinfo: provide default readline-appendix finder
198 (doc/Makefile knows how to make one for local config)
200 * Makefile.in: use doc/Makefile for doc targets
202 * doc/Makefile: GDB documentation now has its own Makefile
203 doc/refcard.tex: renamed from "gdbrc.tex"
204 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
205 doc/gdbint.texinfo: add markup in "Cleanups" chapter
208 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
210 * values.c (baseclass_addr): When reading target memory, use the
211 length of the basetype, not the upper type. We've only malloc'd
212 enough space for the basetype, leading to errors in free().
214 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
215 ends up as a function specially, since we know the actual type of
216 the pointed-to address. This (somewhat) fixes display of
217 expressions that include misc_function_vector names. Try `cond 1
218 !strcmp("a","b")' then `i b'.
220 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
221 The child can be proceeded from inside wait_for_inferior in
222 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
223 getting skipped in that case.
225 * expprint.c (print_subexp): Use filtered output, since the
226 subroutines we call use it, otherwise the output is horribly
227 mangled, since output of wrappable stuff comes out late.
229 * Makefile.in: Bump VERSION to 3.98.1
231 * infrun.c (child_create_process): Use execlp to find the
232 shell to exec our target program. This requires some fiddling
233 with `environ' since there is no execlpe().
235 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
237 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
238 Minor rearrangement of refcard permits two new make targets--
239 gdbrc.dvi DVI output for refcard, using CM fonts
240 gdbrc.ps PostScript refcard, using PS fonts
242 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
246 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
247 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
249 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
251 * doc/gdb.texinfo: last changes for release.
252 Minor typo and formatting fixes; incorporated most fixes remaining from
253 filed mail commenting on earlier drafts.
255 Added warnings: pipes don't work in run command;
256 conditions are converse of assertions;
257 step over fn without debug info goes to next fn;
258 vars may have "wrong" values near fn entrance, exit
260 Added example from Kingston on printing repeated nonadjacent values
262 Added explicit mention that in Emacs gdb mode C-c and C-z are like
263 shell mode for signals
265 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
266 doesn't sound so much like its parent "Stopping and Continuing"; also
267 moved entries on continue to top of section, so they don't get lost.
269 Improved installation directions in appendix, added manual formatting
272 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
274 * configure.in: Remove xm.h and tm.h even if we aren't linking
275 new ones, so "./configure sun4; ./configure none" does the right
276 thing. Assume that alldeps.mak and depend are already built in
277 srcdir, and avoid running "make" (particularly "make depend",
278 which involves "gcc") from inside configure. Build Makefile
279 directly rather than building Makefile.conf first.
280 * configure: Regenerate with above changes.
281 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
282 to 3.98. Revise gdb.tar.Z procedure to produce a file
283 called gdb-$(VERSION).tar.Z but which unpacks into a
284 directory called "gdb". Move non-source files out of
285 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
286 (depend): Don't try to do "gcc expread.y".
287 (expread.o): Update dependencies by hand.
289 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
292 Fixed a variety of small typos that prevented info from formatting
293 cleanly; altered too-long heading for GPL Appendix, as discussed
294 w/RMS; Changed date on cover to July 91.
296 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
299 (1) Applied some fixes due to comments from Larry Breed (easier ones
301 (2) Eliminated use of @footnote---had my doubts about it anyways, and
302 it's broken in latest texinfo
303 (3) Introduced *some* use of [] for optional arguments, where
304 explanation is not simpler by listing cmd w arg and cmd w/out arg
305 separately. Still not using @deffn.
306 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
307 couple of headings are too long. Need patches to texinfo or revision
310 * Partial update to README (which still needs work for this
311 release!): (1) use of configure corrected for new script,
312 (2) "make gdb.dvi" and "make gdb.info" mentioned.
314 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
316 * symtab.c (lookup_symbol): Don't complain right off about
317 no debug symbols; use the misc function vector first.
318 (list_symbols): Use misc function vector to find symbols
319 that don't have debug info, and print them.
320 (find_pc_symtab): Temporarily avoid fatal() when psymtab
321 PC range doesn't match symtab PC range, as it does on the
322 MIPS because our symtab reading isn't perfect.
324 * dbxread.c (dbx_symfile_read): Make warning about
325 "no debug symbols" slightly nicer.
327 * source.c (select_source_symtab): If "main" symbol exists,
328 but decode_line_spec can't find line info, don't just return
329 a zero; try other source symtabs or give an error.
331 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
332 their low addresses first, then rip through fixing high addrs.
334 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
336 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
338 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
340 * Minor, mostly mechanical, cleanup of doc subdir for clean
341 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
342 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
344 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
346 Mostly MIPS and general symbol-reading fixups.
348 * doc/gdbint.texinfo: Add documentation on symbol-reading
351 * mipsread.c: Remove kludges around #include "ecoff.h".
352 Remove redefinitions of a_magic, etc, no longer used.
353 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
354 Fix global overview comments to match symfile.c protocol.
355 (mipscoff_new_init): Eliminate cur_hdr if we have one.
356 (mipscoff_symfile_read): Eliminate unused code. Avoid
357 sorting all the symtabs, when all we have read here is psymtabs.
358 The symtabs are sorted as they are created anyway. Tell
359 condense_misc_bunches whether we're mainline.
360 (psymtab_to_symtab_1): Pass filename when recursing, to make
361 stack trace more informative.
362 (parse_partial_symbols): Assume cur_hdr as argument.
363 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
364 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
365 the TYPE_NAME of char *, since that's done in symfile.c.
366 (free_numargs, parse_symbol, add_symbol, add_block,
367 shrink_linetable): Declare these fns void.
368 (upgrade_type): Convert tree of if's to switch. Clean up
369 bogus "off == 0" handling with a complaint. Avoid setting
370 field bitpos and bitsize of array with lower and upper bounds.
371 Check specified bitsize of elements against their actual type's
372 bitsize, and complain if different. Complain about unknown
374 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
375 (psymtab_to_symtab_1): Print names of subsidiary files that
376 are being read in. FIXME, we read far too many files. This code
377 is not the problem, the problem is in parse_fdr where the psymtabs
379 (cross_ref): Result should indicate that we used one aux entry
380 normally, or two if we encountered a "next" entry. This used
381 to leave the caller pointing at the wrong aux entry.
382 (add_symbol): If overflowed cur_block, reallocate it larger,
383 chase all pointers to it, and complain(), rather than clobber memory.
384 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
385 (new_field): Only allocate one field initially, not two.
386 Pull ++ out of macro argument. Simplify.
387 (_initialize_mipsread): Avoid initialization of importd
388 global_psymbols and static_psymbols.
390 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
391 to properly set pst->symtab; avoid searching for it.
392 (symfile_fns): Improve comments, add a FIXME.
393 * dbxread.c: Update comments to reflect symfile protocol.
394 (read_ofile_symtab, end_symtab): Return the symtab.
395 (psymtab_to_symtab_1): Set pst->symtab.
397 * coffread.c (coff_symfile_read): tell condense_misc_bunches
398 whether we're mainline.
400 * symfile.h (sym_fns): Remove unused sym_discard member.
401 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
403 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
404 the environment variable is not.
405 * infcmd.c (finish_command): Use filtered printfs.
406 * cplus-dem.c: Add struct tags to a few unnamed structs.
407 * valops.c (value_coerce_array): Improve comments.
408 * valprint.c (type_print_varspec_suffix): Print array size only
409 if greater than zero.
410 * m88k-tdep.c: Shift some lines left by one space, that had
411 apparently been trashed at some point.
412 * TODO: More things to do, a few got done.
414 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
416 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
417 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
419 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
420 * expread.y, findvar.c, symmisc.c: Ditto.
421 * printcmd.c (address_info): Update printed forms of LOC_
422 symbols. Elim LOC_EXTERNAL.
423 (print_frame_args): Keep track of param stack offsets before
424 re-looking up to find the local register param is kept in.
426 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
427 Further integration of mipsread into gdb. Eliminate unused
428 routines, duplicate declarations. Handle static symbols in
429 psymtabs as well as external symbols. When reading symtabs,
430 insert symbols into the correct block (global, static, or a local
432 (read_mips_symtab, parse_partial_symbols): Don't pass useless
434 (mipscoff_symfile_read): Don't call select_source_symtab.
435 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
436 rather than SYMBOL_VALUE.
437 (parse_external): Comment clobbering of top_stack.
438 (parse_partial_symbols): Update comments. Allocate and parse
439 static symbols as well as external symbols. FIXME, enum values
440 are not handled in this pass, but should be. Inline new_psymbol.
441 Use SYMBOL_VALUE_ADDRESS.
442 (psymtab_to_symtab_1): Read symbols into global static block
443 by default (until enter some function's local block context).
444 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
445 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
447 * source.c (select_source_symtab): Select a source symtab
448 from either the symtabs or, failing that, the psymtabs.
449 (list_command): Update error message.
450 (forward_search_command, reverse_search_command): Use getc, not
451 fgetc, for speed. FIXME, add comment about buffers that die if
452 overrun by long line.
454 * values.c (unpack_field_as_long, modify_field): Avoid shifting
455 by an entire word, which is not portable, if we have a 32-bit
456 field. (Code in dbxread.c already turns such bitfields, if
457 aligned, into ordinary ints, but fixing this will help for other
458 symbol formats and for future changes.)
459 * core.c (core_open): Handle ANSI const brain death.
460 * utils.c (vprintf): Fix varargs typo.
462 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
464 * findvar.c (find_var_value): Handle &function better.
465 * TODO: Document work needed on &fn and &array.
466 * printcmd.c (print_address_symbolic): New arg is the prefix
467 to print if a name is printed.
468 (print_address_demangle): Honor "set print address" now.
469 Use new arg above to improve spacing of output.
470 * valprint.c (val_print): When printing function pointers,
471 print symbolic form too.
472 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
474 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
476 * core.c (memory_error): Reword error msg to mislead less.
478 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
480 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
481 parse_partial_symbols): Use newer BFD internals (external_filehdr
482 and external_aouthdr), byte-swap the fields that we care about
483 before using them, and make the file header data local to
484 read_the_mips_symtab rather than global.
486 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
488 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
489 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
491 * main.c (command_line_input): Flush stdout and stderr
492 before every call to readline. This reportedly fixes a bug
493 that comes up in Sys V running emacs-gdb and/or xxgdb,
494 when stdin/out are pipes or sockets.
496 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
498 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
499 Avoid declaring Makefile dependencies, because GNU Make stupidly
500 tries to update it if we do.
502 * coffread.c: Revise for minor changes to bfd internal coff
505 * configure: If -template= is given a relative path, make it
506 absolute before recurring in subdirectories.
508 * configure, configure.in, Makefile.in: Install "configure" script
509 as replacement for config.gdb.
510 * config.gdb, Makefile.dist, Makefile.sdir: Remove
511 * README: Update for configure, mostly. FIXME.
513 * Add dec3100 as equivalent to littlemips. Indicate in all host &
514 target config files that they are for the host. When the lines
515 get copied into the Makefile, this makes it more obvious what's
518 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
520 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
521 tabs, which end up in the disassembler output inadvertently.
523 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
525 Make it compile cleanly in an ANSI GCC2 environment.
527 * blockframe.c: <stdio.h>
528 * cplus-dem.c: free takes a void *, ifdef __STDC__
529 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
531 * defs.h (alloca): Avoid doing anything if alloca already def'd.
532 * stddef.h, stdlib.h: Remove these files.
533 * symtab.c: Avoid declaring qsort, close.
534 * symfile.c: Avoid declaring close.
535 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
536 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
538 Assorted other changes.
539 * dbxread.c: include "libaout.h", not "liba.out.h".
540 * printcmd.c (print_frame_args): Set recurse properly for
541 indentation of struct and array parameters.
542 * valops.c (value_cast): Allow cast to void.
543 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
544 single_step() in a target-independent fashion.
545 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
546 set up to be ready to continue. This makes us target independent.
547 * infptrace.c (child_resume): Remove call to single_step; now
548 can single step a SPARC target of any kind.
550 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
552 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
553 docn into separate sections---basically chapters, plus two loose
554 pieces that can be configured to go in different places. This
555 allows GNU m4 to preprocess the manual without coredumping.
557 * Makefile.dist: tell TeX where to find texinfo.
559 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
561 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
562 the new target "rdl-apps.texinfo" which captures the Makefile
563 variable that records where to find the Readline libraries.
565 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
567 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".

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

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

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

1223 (add_target): Call add_cmd and mess with targetlist->doc.
1224 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
1225 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.

1258 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1260 Permit symbols to be superseded when new symbol files have
1261 been read in, particularly for VxWorks.
1263 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
1264 to the main file, as well as to include files. Also, put global
1265 functions into the global psymtab, to make "i fun" work.
1266 (end_psymtab): Free named symtabs and psymtabs for a file, once a
1267 new psymtab for it has been read.
1268 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
1269 a file, once a new symtab has been read for it.
1270 * mipsread.c: FIXME. We need to do the same for MIPS, but it
1271 looks harder to determine the top-level block before it's been
1272 queued to the psymtab list.
1274 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
1275 If we have wiped out any old symbol tables, clean up at end of
1277 (symbol_file_command): Don't reference symfile_fns if it's zero.
1279 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
1280 defines for the blocks of a blockvector that contain global and
1281 file-static symbols and the first of the smaller scope contours.
1282 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
1283 decode_line_1, make_symbol_completion_list): Use the above.
1284 * coffread.c (end_symtab, patch_opaque_types): Ditto.
1285 * dbxread.c (end_symtab): Ditto.
1286 * expread.y (block): Ditto.
1287 * mipsread.c (throughout): Ditto.
1288 * symmisc.c (free_named_symtabs): Ditto.
1290 * symtab.c (list_symbols): Process the first symbol of the
1291 static psymbols list.
1292 (types_info): Restore this function from its untimely #if 0.
1293 It's not perfect, but it is better than nothing.
1294 (_initialize_symtab): Restore "info types".
1296 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1298 * m68k-stub.c: Remote stub for 680x0's, created from
1299 rem-m68k.shar (which is removed).
1300 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
1301 Remove RCS log stuff now that we use CVS and it blows our diffs.
1303 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1305 * symmisc.c (free_named_symtab): Make it work, in its current
1306 kludgy fashion. Change result to indicate if we blew away bkpts.
1307 * dbxread.c (end_symtab): Accumulate result from
1308 free_named_symtab and print warning if we blew user's state.
1309 * symfile.h: free_named_symtab now returns an int.
1311 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1313 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
1314 is the first symbol read, even if not mainline.
1315 (dbx_psymtab_to_symtab): symfile might be zero, cope.
1316 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1317 (set_section_command): New command ("section xxx yyy" -- should
1318 be renamed to "set section xxx yyy" FIXME) which sets the
1319 base address of a section of the exec file, overriding the
1320 virtual address that BFD reports.
1322 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1324 * exec.c: Add add_syms_addr_command to exec_ops, so you can
1325 load symbols at any address while examining an exec file.
1327 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1329 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1330 for printing the float info is host-dependent, not
1331 target-dependent. FIXME.
1332 * i386-pinsn.c: Move #includes to top, remove useless ones.
1333 * i386-tdep.c: Don't bother including <.../reg.h> since we
1334 don't use it (and it doesn't exist on host systems).
1336 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1337 Convert negative numbers properly.
1338 (ieee_test): Make numbers really random; fix format arg.
1340 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1341 * core.c (core_detach): Unpush core_ops, which might not be on
1342 top. We used to just pop the top, which broke things. Don't
1343 need dont_repeat() any more.
1344 (core_file_command): Psst! Don't repeat it.
1345 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1346 * expprint.c (print_subexp): Avoid switch fallthru on
1347 BINOP_ASSIGN_MODIFY, so we can print += and such.
1348 * frame.h: Fix typo.
1349 * inflow.c (kill_command): After killing inferior, print our
1350 current frame in the core file, if we have one.
1351 (generic_mourn_inferior): When inferior dies, either select
1352 the current frame (in the new target, e.g. core file), or
1353 set both the current and selected frames to NULL.
1355 Changes from Peter Schauer.
1357 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1359 * Make all file names fit in 14 characters (sigh and damn!):
1360 mv hp300hpux-xdep.c hp300ux-xdep.c
1361 mv symmetry-xdep.c symm-xdep.c
1362 mv symmetry-tdep.c symm-tdep.c
1363 mv convex-opcode.h convx-opcode.h
1364 mv tm-vxworks960.h tm-vx960.h
1365 mv tm-vxworks68.h tm-vx68.h
1366 mv Makefile.srcdir Makefile.sdir
1367 mv gdb-int.texinfo gdbint.texinfo
1368 mv remote-sa.m68k.shar rem-m68k.shar
1369 mv remote-multi.shar rem-multi.shar
1370 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1371 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1372 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1375 * command.c (user_info_1, user_info): New command for listing
1376 the user-defined commands.
1378 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1380 * dbxread.c (really_free_pendings): Clear file_symbols
1381 and global_symbols after freeing them; otherwise, running
1382 this function twice (if it appears twice on the cleanup
1383 chain), we try to free things twice.
1385 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1386 based on text_addr (the address of text in core), not on addr (the
1387 offset between text in the .o file and in core). This change
1388 is from Peter Schauer.
1390 * main.c: Define ALL_CLEANUPS as a cast of zero.
1391 (return_to_top_level): Use it.
1392 (main): Do all cleanups after each command run as part
1393 of the gdb startup sequence. Also do all cleanups before
1394 entering the command loop, and every time we exit the command
1395 loop and reenter. Before, the cleanups from the startup sequence
1396 were being left undone until the first error!
1397 (command_loop): Rename do_nothing cleanup to command_loop_marker
1398 so we can see it easily when examining the cleanup chain.
1399 (init_signals): Add another do_nothing for signal handling.
1400 (quit_command): Only try to kill target if it has execution.
1401 Problems in the target stack got us into a state where
1402 inferior_pid was nonzero but none of the targets had execution.
1403 In this state you couldn't exit gdb.
1405 * dbxread.c: Two changes from Peter Schauer.
1406 (echo_command): Fflush output after an echo command.
1407 (show_history): Pass all args to cmd_show_list.
1409 * utils.c (init_malloc): Call mtrace to turn on tracing
1410 if the environment variable MALLOC_TRACE is set to a file name.
1411 * mtrace.c: Add source file which provides a log of every malloc,
1412 free, and realloc to a trace file.
1413 * mtrace.awk: Add source file which analyzes the trace file.
1414 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1415 (VERSION): Roll to 3.94.3.
1417 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1418 (check_duplicates): Don't bother with watchpoints.
1419 (set_raw_breakpoint): Comment about danger of this routine.
1420 (watch_command): Parse and eval all args before calling
1423 * solib.c (find_solib): Avoid error in referencing memory to
1424 see if any more shared libraries have been added. This is
1425 particularly useful if the target has terminated. Bug reported
1428 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1429 in bringing up 3.94.2 on the Sun-3.
1431 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1432 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1433 expression (in scope) before reenabling watchpoint.
1434 * signame.c (init_sigs): Add missing declaration of i, fix
1435 sys_siglist declaration.
1436 * source.c (list_command): Fixed range computation to use
1438 * stack.c (backtrace_command): Do not allow command if target has
1439 no stack, print informative error message.
1440 * target.c (target_command): Do not write into command line
1441 because this fails if the target command is used in a user defined
1442 command. [This change was enhanced by gnu to support any-
1443 unique-prefix matching on target names.]
1444 * valops.c (value_struct_elt): Avoid infinite loop on an
1445 erroneous attempt to print the member of function (try p main.p).
1447 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1449 * expread.y (name_no_typename): Avoid reduce/reduce errors
1450 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1451 Since the GDB parser really doesn't use name_no_typename in a
1452 name-only context, the parser can't tell the diff between
1453 names and numbers here. Avoid allowing a name_no_typename
1454 to be a NAME_OR_*INT to resolve the conflict.

1458 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1460 * valprint.c (val_print_fields): bitfield printing didn't handle
1461 byte order. Indirect through a few more fns to cope.
1463 * values.c (modify_field): also cope with byte order.
1465 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1467 Cleanup for release 3.94.2:
1469 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1470 include files. Roll version to 3.94.2.
1472 * coffread.c (init_stringtab): Read length into unsigned char
1473 array before swapping; don't assume 32-bit longs.
1475 * target.c (target_info): Don't bother with get_sym_file, just use
1476 the symfile global variable.
1477 * symtab.h, symfile.c (get_sym_file): Delete it.
1479 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1480 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1481 (read_type): Replace one more error() with complain().
1483 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1485 * i960-tdep.c: Fix copyright attribution.
1487 * config.gdb: Quote all backquotes in doublequotes. You can
1488 quote me on that. BSD 4.4 shell found this one.
1490 * infptrace.c (throughout): The third argument to ptrace is an
1493 * infrun.c (wait_for_inferior): When program has terminated, we
1494 have to call target_terminal_ours before we pop that target off
1495 the stack (e.g. before a call to target_kill or
1496 target_mourn_inferior). This fixes problem where a program
1497 terminates, then GDB stops for (tty output) and you have to type
1498 "fg" to the shell to resume it. FIXME: This code for what to
1499 do after termination really should be in normal_stop instead.
1501 * gdbcore.h (read_memory_check): Change declaration; it changed
1504 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1505 4.4 prereleases, this avoids a bug in their sgtty compatability
1507 * remote.c: Use terminal.h rather than hand-rolling the same.
1509 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1510 * utils.c (strsave, strstr): Fix arg types.
1511 * valprint.c (val_print): lint
1513 MIPS symbol table support from Per Bothner:
1515 * symfile.c (symtab_fns): Remove initializer table that needs to
1516 be hacked for each new symbol file format supported.
1517 (add_symtab_fns): New function, chains symbol table
1518 handlers into the global list.
1519 (symfile_init): Search this list.
1520 * symfile.h: Add next pointer, declare add_symtab_fns.
1521 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1522 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1524 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1525 symbol *). Thus, we no longer need the hack to trash
1526 pst->filename. Good, since that hack confused code in symfile.c!
1528 (reorder_symtabs, destroy_all_symtabs): Removed static
1529 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1530 Instead, the latter now uses a temporary array (stack-allocated
1531 from an obstack, and then freed).
1533 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1534 haven't been set in the outermost stBlock of a procedure. This was
1535 a problem with f77 binaries on Ultrix 4.?.
1537 (new_symtab, new_symbol, new_type): Continue changing code to use
1538 obstacks more and otherwise conform to dbxread internal style.
1539 Made the free_code of symtabs be free_linetable (as in dbxread)
1540 instead of free_contents. This implies memory leaks when reading
1541 a new symbol table, until the conversion is finished. Did change
1542 (struct symbol) and (struct type) to be allocated on the
1543 symbol_obstack. Blocks and blockvectors are among the things
1546 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1547 tested much, but it solved one problem (reported by Meissner), and
1548 cleans up some other things. The problem happened when an
1549 included file contains actual code (functions) and not just
1550 definitions. The mips coff is a little inconvenient there, since
1551 it may cause a procedure to be mapped to the wrong psymtab.
1553 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1554 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1555 this will need work for the new core paradigm.
1557 Opcode patches from the net:
1559 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1560 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1561 missing altogether - they are added here. From Bruce Bauman.
1562 * mips-opcode.h: The low mask for C0 instructions was too small.
1563 From Garrett Lau. I modified the fix to check the entire 32-bit
1566 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1569 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1571 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1573 * dbxread.c (read_type): Pointer subtraction (value_sub in
1574 valarith.c) sometimes failed because the types of the
1575 pointers being subtracted were not identical.
1576 These differed because dbxread.c was allocating pointer types
1577 using dbx_alloc_type+smash_to_pointer_type instead of
1578 lookup_pointer_type. I failed to find a justification for the
1579 former, so I changed it to use the latter. Similarly, I
1580 replaced smash_to_function_type by lookup_function_type,
1581 and smash_to_reference_type by lookup_reference_type.
1583 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1584 _initialize_mipsread): corresponding changes.
1586 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1588 * source.c (mod_path): Do tilde_expand on each component of the path,
1589 rather than on the (list of) paths as a whole.
1590 (print_source_lines): Set first_line_listed in addition to
1591 current_source_symtab and current_source_line. If the source was
1592 not findable, after a "dir" command to fix the problem,
1593 a "list" would get the wrong lines.
1595 While I was there... (gnu):
1597 * dbxread.c (read_type): Change error to complaint.
1599 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1601 First attempt at detailed understanding of symbol table memory alloc.
1603 * dbxread.c (dbx_symfile_read): Free our string table if we
1604 aren't the mainline. Free the "info" struct since we're done with
1606 (init_psymbol_list): Free any previously allocated psymbol lists.
1607 (): FIXME: Should realloc-down the psymbol lists when done reading
1608 the main symbol file?
1610 * symmisc.c (free_symtab): Free fullname field too.
1612 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1613 (REGISTER_ADDR): Make result type unsigned int.
1615 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1616 define REGEX must also define REGEX1 (its dependency).
1618 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1620 * tconfig/i960: No longer works, points you at vxworks960 or
1623 * xgdb.c, XGDB-README: Remove file. Users can get the much
1625 * Makefile.dist: Remove all trace of xgdb.
1627 * breakpoint.c (breakpoint_1): Pass demangle arg to
1628 print_address_symbolic.
1629 (clear_breakpoints): Remove unused function.
1630 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1631 (breakpoint_re_set): Use catch_errors to do them all anyway.
1633 * gdb-int.texinfo (Host versus Target): Add section on what is
1634 a "host" feature versus what is a "target" feature.
1636 * infcmd.c (path_command, path_info): Handle the PATH variable
1637 (object search path) as conveniently as the source search path.
1638 * environ.c (set_in_environ): Set some vars in GDB's environment,
1639 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1640 * source.c (mod_path): New function, from guts of
1641 directory_command, modifies a path. Used by path_command.
1642 (directory_command): Call it.
1643 * defs.h (strsave): Declare.
1645 * utils.c (sevenbit_strings): Add new printing option.
1646 (printchar): Use it.
1647 (strsave): Provide this handy helper routine.
1648 (set_width_command): Rename set_screen_width_command.
1649 (_initialize_utils): "set screen-width" => "set width";
1650 "set screen-height" => "set height"; add sevenbit-strings.
1652 * infcmd.c (do_registers_info): Print floating point registers
1653 in raw hex as well as float format, regardless of whether it is
1654 a "virtual" convertible register.
1655 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1656 regs as a double, just in case it's being used that way.
1657 * values.c (unpack_long): Comment on array/function coercion.
1658 (unpack_double): Argument is in target byte order now. For
1659 integer arguments, just call unpack_long and float the result.
1660 * m68k-tdep.c: include defs.h for "const" handling.
1661 * remote-nindy.c: Use ieee-float stuff.
1662 (nindy_fetch_registers): Unpack double regs to host double, then
1664 (nindy_store_registers): Pack extendeds to host double, flip
1665 around by misusing unpack_double, send as target double.
1667 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1668 zero, as when stopped at the first instruction of a process.
1670 * blockframe.c: Fix filename in comment (param.h => tm.h).
1671 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1672 * tm-68k.h: Fix typos.
1674 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1676 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1678 * coredep.c (fetch_core_registers): Pass end-address of register
1679 section to register_addr as expected. Don't call supply_register
1680 if we'd just pass it garbage.
1682 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1684 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1686 * target.c (push_target, target_info): Cast enums to int for < or
1689 * stack.c (print_frame_info): Identify source file & line
1690 even if we can't print it.
1692 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1694 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1696 Clean up IEEE floating point support.
1698 * ieee-float.h: New file.
1699 * ieee-float.c: Write real routines to convert between host
1700 doubles and various target IEEE extendeds.
1701 * m68k-xdep.c: Eliminate assembler code for extended floats.
1702 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1703 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1704 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1705 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1706 double_to_ieee_extended.
1707 * i960-tdep.c: Define ext_format_i960.
1708 * m68k-tdep.c: Define ext_format_68881.
1709 * sparc-tdep.c: Define ext_format_sparc, though unused.
1710 * Makefile.dist (HFILES): Add ieee-float.h.
1711 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1714 Obsolete the "coffstrip" program in favor of using BFD's strip.
1716 * nindy-share/coffstrip.c: Remove file.
1717 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1718 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1719 * tconfig/nindy960: Remove reference to coffstrip.o.
1721 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1723 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1725 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1726 * dbxread.c: Remove static symfile_bfd.
1727 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1729 * inftarg.c (child_detach): Pop the child_ops vector if the
1730 detach is successful.
1731 * remote-nindy.c (nindy_create_inferior): Don't push a new
1732 nindy_ops since nindy uses the same one for execution and memory
1734 * core.c (core_ops): Use child_attach and child_create_inferior
1735 rather than default attach and create_inferior functions.
1737 Handle floating point registers in core files.
1739 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1740 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1741 This version untested since BFD doesn't yet support sun3 core
1743 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1744 conventions. Fix comments and style. This version has not
1745 been compiled yet, since we have no HP inhouse.
1746 * core.c (get_core_registers): Look for two sections, ".reg"
1747 and ".reg2", and pass both to fetch_core_registers sequentially.
1749 Revise directory path yet again.
1751 * source.c (forget_cached_source_info): Not static any more.
1752 (init_source_path): New default source path is "$cdir:$cwd".
1753 (dir_command): Handle variable arguments ($cdir, $cwd).
1754 (source_info): Print "Compilation directory" rather than
1755 "Originally compiled in" to remind people of $cdir.
1756 (openp): If the path contains $cwd, use current directory.
1757 (open_source_file): If compilation directory is known, replace
1758 first $cdir in path with the compilation directory.
1759 (print_source_lines): Even if we can't print the lines, set the
1760 current symtab and line for future commands like "info source" or
1761 "breakpoint". Also, error message now contains the file name,
1762 line number, and file access error message.
1763 (_initialize_source): Fix help text to describe changes.
1764 * main.c (cd_command): Forget cached source info when we chdir.
1765 * utils.c (strstr): Add simple implementation.
1767 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1769 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1770 Byte-swap COFF symbol tables if necessary when reading them in.
1771 Use complain() to replace error message in one spot. Needs
1772 corresponding change in bfd/coff-code.h to make some symbol
1773 swapping routines non-static.
1775 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1777 Merge changes from Eirik Fuller, for UTek.
1779 * defs.h (errno): Add declaration.
1780 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
1781 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1782 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1783 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
1784 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
1785 declarations of errno.
1787 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1789 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1790 <rpc/rpc.h> and <rpc/types.h>.
1792 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1794 * i960-tdep.c (examine_prologue): Add new argument limit,
1795 which stops the scan at the end of the prologue, or at the PC.
1796 This fixes a problem where it walks down into the code for the
1797 user's statements if that code looks like function prologues.
1798 Mark Fox and I have been bouncing this code back and forth, making
1799 small changes to it. Callers changed to match.
1801 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1803 Cleanup for gdb-3.94 release final:
1805 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1806 the .c files from vx-share and nindy-share, from the various
1807 macros, since they are not found via ALLDEPFILES.
1808 (SFILES): Add tm-i960.h.
1809 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1810 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1812 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1813 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
1815 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
1817 * am29k-tdep.c: Add contribution line.
1818 (examine_prologue): Cache information about function prologues in
1819 the misc-function-vector to avoid lots of references over the
1820 serial line while examining instructions.
1822 * core.c (core_close): New function made from cleanup_core.
1824 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1825 remote-vx.c, remote.c, target.c, target.h,
1826 Update target_ops vector to add attach, close, and load entries.
1827 Use add_syms_addr_command, not add_file_addr_command, for
1828 add_file. Break out close routine from existing code.
1830 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1831 they are in an obstack.
1832 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1834 (define_symbol): Add symbol type parameter; change callers;
1835 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1836 it to influence the symbol class on the i960.
1837 (define_symbol): Swap LOC_CONST's into target byte order.
1839 * exec.c (exec_close): New function.
1840 (exec_file_command): Call it.
1842 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1843 Fix byte order of frame pointer.
1844 (read_var_value): Result of 0 if var's value can't be found,
1845 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1846 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1847 (locate_var_value): Use read_var_value and use its lazy address
1848 as the location of the var's value. Lint.
1850 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1853 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1854 obsolete Intel versions in favor of vxgdb versions.
1855 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1856 code dealing with byte order of values, which Intel did in host byte
1857 order rather than gdb-4's target byte order.
1858 (i960_frame_chain_valid): Move to nindy-tdep.c.
1859 (examine_prologue, skip_prologue, frame_find_saved_regs,
1860 frame_args_address, leafproc_return, saved_pc_after_call,
1861 pop_frame): Add vxgdb versions from Mark Fox.
1862 (examine_prologue, frame_struct_result_address): Add code
1863 to deal with the saved value of G13 (struct return address
1865 (frame_args_address): Modify Mark's version to prefer the
1866 saved value over the current value in the topmost frame.
1867 Cache result in the frame info to avoid performance hair in
1869 (print_fault): Add gdb960 code for printing faults.
1870 (_initialize_i960): Actually call check_host.
1872 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1873 add stub routines. FIXME, these currently just return zero!
1875 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1876 (attach_command): Call target_attach, not target_open, now.
1878 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1879 (child_attach): Rename from child_open.
1880 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1881 don't confuse it with a zero step_resume_break_address.
1883 * inftarg.c (child_detach): Eliminate inferior_pid test.
1884 (child_files_info): Clean up message a bit.
1885 (child_ops): Use child_attach, not child_open, to attach.
1887 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1888 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1889 findvar.c to here, since it depends on the contents of the
1890 shadow_contents of breakpoints, but keep if #if 0 since it is
1893 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1896 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1897 (ptype_command, display_command): Eliminate have_inferior_p and
1898 have_core_file_p in favor of target_has_stack or
1899 target_has_execution.
1900 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1901 code for actually finding the values of arguments, though we still
1902 keep track of the maximum stack offset for use in printing unnamed
1903 arguments. Handle missing FRAME_ARGS_ADDRESS.
1905 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1906 (struct nindy_regs): Define registers passed to/from nindy.
1907 (nindy_fetch_registers, nindy_store-registers): Translate between
1908 nindy and GDB formats for the registers.
1909 (dcache_init): Statically allocate the cache, since it was being
1910 allocated by a malloc that was never freed anyway.
1911 (nindy_create_inferior): Error, not core dump, if no exec file.
1912 (nindy_before_main_loop): Use target_load, not target_add_file.
1914 * remote-vx.c (net_load): Specify large timeout for load
1915 requests. Allow user to break out with INTERRUPT.
1916 (net_break): Remove useless code, clean up. Change callers.
1917 (parse-args, skip_white_space, find_white_space): Clean up arg
1918 parsing to cope with quoted strings.
1919 (net_wait, net_quit): Never call error, just return status.
1920 (vx_read_register, vx_write_register): Cleanup status checking.
1921 #ifdef the code based on which CPU we are using (960 or 68k),
1922 FIXME, this should be completely general but it isn't yet.
1923 (vx_xfer_memory, vx_resume): Cleanup status checking.
1924 (vx_run_files_info): Improve message.
1925 (vx_load_command): Renamed from vx_add_file_command. Allow load
1927 (net_ptrace): Remove unused routine.
1928 (vx_wait): Adopt code from vxgdb960 to cope with broken
1929 connections to target machine and prompt to disconnect. Remove
1930 debug printouts. Map some EVENT_'s to SIGnals.
1931 (add_symbol_stub, vx_open): Print names of object files we found,
1932 and "ok" if we read their symbols OK. Clarify output in general.
1933 (vx_attach, vx_detach, vx_kill): Add these commands.
1934 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1935 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1936 "info files" output, and create_inferior, since we already have
1939 * stack.c (frame_info): Replace Frame_unknown with 0.
1940 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1941 (return_command): Pop until the PC matches as well as the FP,
1942 so it works even if the FP is shared with another function,
1943 as in "frameless" or "leaf" procedures.
1945 * symfile.c (load_command): renamed from add_file_target_command.
1946 (add_syms_addr_command): renamed from add_file_addr_command.
1947 (add_syms_command): Stub to call target_add_syms.
1948 (_initialize_symfile): Change command names and descriptions,
1949 add-file => add-syms, and load from alias to its own command.
1951 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1952 maybe_kill_then_create_inferior): Default for attempts to start
1953 a process, if one is already running, is to ask about killing
1954 it and retry if yes.
1955 (upstack_create_inferior): #if-0 it, strata obsolete it.
1956 (push_target, unpush_target, pop_target): to_close() a target
1957 before unstacking it.
1958 (target_info): Renamed from target_files_info.
1959 (_initialize_targets): Rename "i files" as "i target", accessible
1962 * target.h: Improve comments about the target_ vectored routines.
1964 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
1965 Convert commenting style to standard GNU style.
1966 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
1967 (SKIP_PROLOGUE): No longer a no-op.
1968 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1969 (*_REGNUM): Sort register numbers.
1970 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1971 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1972 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1973 are now 10 byte extendeds, not 8 byte doubles.
1974 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1975 for nindy versus vxworks targets. FIXME, this should possibly go
1976 in the target vector.
1977 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1978 frame_saved_regs and arg pointer with each frame.
1979 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1980 (FRAME_ARGS_ADDRESS): Use cached result.
1981 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1982 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1983 (PRINT_RAMDON_SIGNAL): Call print_fault.
1984 (POP_FRAME): Now works.
1986 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1987 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1988 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1989 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1992 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1993 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1995 * valarith.c (value_subscripted_rvalue): Avoid handling
1996 floats and doubles specially; it gave alignment errors. Lint.
1998 * valops.c (value_of_variable, value_of_this): Error if unknown
2001 * valprint.c (print_floating): Bcopy rather than pointer-deref,
2002 to avoid alignment problems.
2003 (value_print): Handle unknown value address.
2004 (cplus_val_print): Two args are ignored; remove them. Change caller.
2005 (val_print): Use unpack_long rather than pointer-deref.
2008 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
2009 to avoid alignment problems.
2010 (value_being_returned): Error if return value unknown.
2011 (set_return_value): Add bogosity warning, FIXME. *
2013 * TODO: A woman's work is never done.
2015 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
2016 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
2017 Add ieee-float.o to OBS.
2018 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
2019 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
2020 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
2022 Changes to generalize the VxWorks RPC protocol slightly, to handle
2023 i960 as well as 68000.
2025 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
2026 * vx-share/reg.h: Produce i960 regs #ifdef I80960
2027 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
2028 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
2029 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
2030 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
2031 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
2032 so they will move in target byte order rather than network
2033 byte order (happens to be the same).
2035 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2037 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
2039 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2042 Add contribution lines to various files, showing where they
2045 * breakpoint.c (break_insn, check_break_insn_size,
2046 read_memory_nobpt): Remove to mem-break.c.
2048 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
2051 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
2052 entry has bad register number. This change is not
2053 tested in this release, FIXME.
2055 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
2058 * value.h: Force value's contents field to be aligned to hold
2059 at least a double or a long long (if supported). This avoids
2060 doing bcopy's in and out of the contents field.
2062 (step_1): Avoid coredump under obscure circumstances when we
2065 * symtab.h (misc_info): Add field to misc function vector for
2066 any kind of cached information the target code desires. AMD
2067 29000 uses this to avoid repeating examine_function_prologue's.
2069 * coffread.c: Lint. Remove static symfile, read_section_header.
2070 core.c (have_core_file_p): Lint: remove.
2071 expprint.c (print_subexp): Lint.
2072 infptrace.c, valops.c, valprint.c: lint.
2074 Roll in changes from vxgdb-5.0.1:
2076 * symtab.h: Comment byte order of each address class. Add
2077 LOC_LOCAL_ARG for frame-relative args (960).
2078 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
2079 symtab.c, symmisc.c: ditto.
2081 * infrun.c (init_wait_for_inferior): Clear stop_signal.
2083 * remote.c (remote_resume): Error if resume with a signal.
2085 * symfile.c (prim_record_misc_function): Clear misc_info.
2086 (fill_in_vptr_fieldno): Check stub type of arg.
2088 * valops.c (value_cast): Avoid looking up names of types whose
2089 name we don't know, to prevent coredump. Sun CC produces typedef
2090 rtx and the name of *rtx is zero...
2092 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2094 Roll in changes from final AMD 29000 port (Tiemann).
2096 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
2097 for ../include/a.out.encap.h. This might not work now that BFD
2098 is separately compiled. Instead, BFD support for encap will have
2099 to translate machine type 29k into the right COFF_MAGIC.
2101 * infcmd.c: Remove references to inferior_pid that aren't used
2102 in actual ptrace calls; use target_has_execution, etc.
2103 (have_inferior_p): Remove function.
2104 (program_info): Print target info rather than "process number";
2105 avoid gratuitous messages unless from_tty.
2106 (run_stack_dummy, finish_command): Set proceed_to_finish.
2107 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
2108 main.c: Lint. Lose have_inferior_p().
2109 inferior.h (have_inferior_p): Remove, lint.
2110 (proceed_to_finish): Add flag to ask that all regs be saved
2111 by normal_stop, for the few commands that need it, speeding up
2112 serial I/O. Add comments to stop_registers.
2114 * remote-eb.c: Remove newline from breakpoint message we grep
2115 for. Never time out when running the user program.
2119 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2121 Roll in changes from vxgdb-5.0.1:
2123 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
2124 symbol in its raw form, we are processing an unlinked ".o" file.
2125 See if the target environment has assigned it an address, using
2126 target_lookup_symbol (VxWorks does), and enter it into the symtab
2129 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
2130 68k versions for a simpler version that assumes zero FP at bottom.
2131 Fixes bug of truncated stack reports.
2133 * target.h (target_lookup_symbol): Define this routine's args
2134 and result, finally.
2136 * target.c (nosymbol): Default routine for target_lookup_symbol.
2137 (target_default): Default lookup_symbol and call_function too.
2138 (files_info): Only print has_all_memory warning if a non-dummy
2141 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
2142 vx_convert_from_virtual): If target does not have floating point,
2143 zero register "values", and avoid doing cross-net conversions.
2144 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
2145 (vx_open): Rearrange code that attaches to target and reads
2146 symbols for all loaded modules, to work if some of the modules
2147 are not accessible. Add symbol_stub() and add_symbol_stub()
2148 as callbacks from catch_errors(). Allow connect attempt to be
2149 interrupted painlessly with ^C (FIXME, there are still some bugs
2150 if the interrupt happens during symbol reading.). Print
2151 final message with puts_filtered, since symbol messages are
2156 * main.c (catch_errors): Only print errstring if non-null.
2157 (command_loop): Avoid an ioctl per command to test ISATTY.
2159 * remote-vx.c (net_load): make static; avoid sophomoric msg.
2160 (vx_xfer_memory): Return correct result!
2161 (vx_files_info): Indicate whether target has float or not.
2162 (vx_lookup_symbol): Complain, not error, if target gone.
2163 (vx_open): Print "Connected" msg before disabling immediate-quit.
2164 [FIXME: lookup_symbol and vx_open changes need testing.]
2166 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
2167 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
2168 contributor lines and update copyrights to 1991.
2170 Changes from an attempted H-PUX host port:
2172 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
2173 defines PT_ATTACH and PT_DETACH but not PT_KILL.
2174 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
2175 * remote-vx.c: include <sys/time.h> for HPUX.
2176 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
2177 "core_file_command" routine to BFD regime. May not work yet.
2179 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
2181 * xgdb.c: Replace X10 version with some VJ version.
2182 (FIXME: Its copyright assignment is not on record.)
2183 * xgdb.c: Update include files to X11R4 (Xaw crud).
2184 (xgdb_display_source, create_text_widget): fix call to
2185 get_filename_and_charpos. Rewack source window stuff for X11R4
2186 (gleaned from include files, and "nm's" of binary libraries, since
2187 I had no doc available).
2188 (append_selection, append_selection_word): Disable with FIXME
2189 since R4 changed interface here.
2190 (create_buttons): Add back the old set of buttons.
2191 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
2193 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
2194 Roll VERSION to 3.94 (not yet final though).
2196 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2198 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
2199 obstack_int_grow, obstack_int_grow_fast): Eliminate
2200 cast on left of assignment, which gives MIPS cc fits and is
2203 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
2204 F_ALIAS. Use printf, not fprintf, when not passing a file
2206 (compare_opcodes): Check that identical instructions have
2207 identical opcodes, complain otherwise.
2209 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
2210 was reported by Roland McGrath.
2211 (unimp): Only match if exactly zero instruction. (Roland)
2212 (branches and traps): Generate all variations of these
2213 instructions with macros, based on a single call that defines
2214 each condition name and its binary representation.
2215 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
2217 * valprint.c (val_print_fields): Take, and use, format parameter.
2218 This means that "p/x struct" again prints the elements in the
2219 desired format. Changed callers.
2221 * stack.c (frame_info): Use filtered output, and indicate wrap
2222 points. Remove kludgy formatting designed to avoid line wrap.
2224 * utils.c (wrap_here): If the line is already full (because
2225 we had printed a long indent or long wrapped string), do an
2226 immediate newline-and-indent.
2228 * m68k-pinsn.c (print_insn_arg): Bugfix from
2229 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
2230 instruction is incorrectly disassembled as bkpt #8.
2232 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
2233 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
2234 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
2235 and then will dump core (sometimes). I traced it back to an
2236 uninitialized symfile_name in psymtab_to_symtab.
2237 (const_vol_complaint): Add quotes to message.
2238 (define_symbol): Only believe line number if gcc_compiled.
2239 Avoid allocating symbol if we will not return it.
2241 Add target strata support so that newly established targets go
2242 into their right place in the target stack (e.g. a new exec file
2243 doesn't wipe out the ability to access the running process).
2245 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2246 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2247 and initialize it properly in all the targets.
2249 * target.h: Document strata. Change return type of push_target.
2251 * target.c (nomemory): new function for dummy memory access.
2252 (tcomplain): Rename complain, now also used in symfile.c.
2253 (push_target): Push targets within strata. New return value shows
2254 whether new target is on top of stack or not. Always keep dummy
2256 (target_files_info): Ignore dummy target.
2258 * core.c (core_open): Warn user, and skip accessing file, if the
2259 core target is not the topmost target in the stack.
2260 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2263 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2264 target_ops, it doesn't belong there since we have no regs there.
2265 Change name of target from machine => memory to clarify.
2267 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2269 * Freeze version 3.93 for release.
2271 * Makefile.dist: Handle vx-share and nindy-share subdirs
2272 properly when building gdb.tar.Z.
2274 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2275 printed in various places, so I could change just one copy.
2277 * dbxread.c, coffread.c: Change references to bfd->iostream
2278 to cast to FILE *, now that BFD avoids needing types defined
2279 in other header files.
2281 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2283 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2284 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2285 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2286 (actually gcc -Wall).
2288 * dbxread.c: Remove first_global_sym, last_global_sym, since
2289 they are never referenced.
2291 * defs.h (baud_rate): Declare.
2292 main.c: Define it, and add the -b option to set it.
2294 * gdb-int.texinfo: Add text on how to define a new host or target
2295 architecture, prompted by Per Bothner's questions about MIPS
2298 * gdb.texinfo: Document "complaints". Change doc of -q since
2299 gdb no longer prints the copyright and blurb if you specify a file
2300 name to be debugged (just like Emacs). Add doc for Nindy-specific
2301 command line flags for specifying target serial port and such.
2302 Update copyright to 1991.
2304 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2305 has taken over for us the job of ripping up executable files. The
2306 crud caused Per Bothner's port to not compile.
2308 * infrun.c (normal_stop): Avoid printing "Program exited
2309 normally" if we are in batch mode. This allows a GDB which
2310 executes a program on a target system, to behave like a Unix
2311 command (input from stdin, output to stdout, no extraneous
2314 * main.c (main): Allow additional machine-dependent command line
2315 options to be specified with the ADDITIONAL_OPTIONS,
2316 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2317 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2318 processing to occur just before the main loop with
2319 BEFORE_MAIN_LOOP_HOOK.
2320 (main): If a "core file" argument is specified, and it is not a
2321 core file, try it as a process ID to attach.
2322 (symbol_completion_function): Attempt to cope with
2323 "show screen-" TAB, not very successfully. This needs more work,
2325 (batch_file): New function, returns whether we are reading
2326 commands from an interactive tty on stdin, or from somewhere else.
2327 Called by normal_stop since it doesn't get from_tty passed down
2328 to it like many commands do.
2330 * remote-nindy.c: Handle command line options for nindy
2332 (nindy_before_main_loop): Prompt user for tty name if they
2333 don't specify it before getting to the interactive command loop.
2335 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2336 and -r command line options. Also add hook before main loop
2337 to make it easy to specify a tty.
2339 * TODO: More things to do, one done.
2341 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2343 * dbxread.c: Make complaint() calls pass pointer, not struct.
2344 Add complaints about badly formatted C++ type information
2345 (const/volatile indicator, and parse errors resulting in
2346 error_type). Fix C++ virtual member fn comment.
2347 (read_struct_type): Avoid bumping pointer if we got a parse
2348 error; this prevents our walking beyond the end of a string.
2349 Terminate loop on null char as well as semicolon.
2350 (process_one_symbol): Fix the LBRAC fix so that it uses the
2351 last previous SLINE, FUN, or SO record's PC address. C++ debug
2352 symbols did not have SLINE records in a useful order compared
2353 to the LBRAC records.
2354 (define_symbol): Handle "catch" records.
2356 * symtab.c (check_stub_type): Added new complain
2357 `stub_noname_complain' and added a consistency check to
2358 keep the debugger from crashing when finishing from an
2359 exception frame. A real fix will be needed later.
2361 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2363 * infcmd.c (attach_command): Make global.
2365 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2366 but make them easy to comment out. Perhaps later they should
2367 be enabled by what CPU you configure for? FIXME.
2368 (VERSION): Roll to 3.93.
2369 (pinsn.o): Remove rule for obsolete file.
2370 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2372 Run down a problem that manifested by printing the wrong function
2373 name in stack traces of read_ofile_symtab. Turned out that the
2374 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2375 the LBRAC symbol with an address in the *data* segment, which
2376 blew our binary search through the blocks.
2378 * dbxread.c: Use the complain() facility consistently to bitch
2379 about problems in the symbol file we are reading.
2380 (finish_block): Add code to check the nesting of the blocks;
2381 complain and Procrust them to fit if wrong.
2382 (make_blockvector): Check the order of the blocks, complain
2383 [but don't cope] if wrong.
2384 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2385 symbols to be sure their PC value is greater than the last SLINE
2386 (line number) symbol we've seen, complaining and adopting the
2387 SLINE PC value if wrong.
2389 * symfile.h (struct complaint, complaint_root, complain,
2390 clear_complaints): Add.
2391 * symfile.c (complain, complaint_root, clear_complaints): Add
2392 facility to deal with non-fatal complaints and to regularize their
2394 (symbol_file_add): Clear complaint counters to allow new complaints.
2395 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2397 * dbxread.c (dbx_symfile_read): Remember the address and size
2398 of the string table for the main symbol file, so we won't read it
2400 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2401 to avoid reading the string table yet again. Lint.
2402 (throughout): Improve filtered output, including word wrap.
2403 (read_range_type): Improve Bothner's fix to handle other types too.
2405 * utils.c: Improve line wrap implementation. Handle unlimited
2406 width by making chars_per_line unsigned.
2407 (puts_filtered): New, easy, function.
2409 * defs.h (puts_filtered): add.
2411 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2412 call the identical sort_symtab_syms() in symfile.c instead.
2414 * expread.y: Suggest the `file' command rather than `symbol-file'.
2416 * command.h (enum var_types): Add zinteger for seroable
2418 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2419 nested if's into a switch.
2421 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2422 we did not stop because of a breakpoint (it must have been for
2423 some other reason, like a "stepi"), so don't print anything.
2425 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2426 doesn't include <sys/types.h>, old SunOS's require it for
2429 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2431 A test port of gdb-3.92.6 to the Sony NEWS.
2434 Don't normally link in remote- or vx stuff.
2435 Some of it doesn't compile, and it wastes space for 99% of the users.
2436 Remove reference to no-longer-used HAVE_VPRINTF.
2437 Fixed BFD_DEP typo to BFD_DIR.
2439 Fix cast in arg to bfd_h_getlong.
2440 Make char *prefix be const.
2441 Fix how certain range types are mapped into builtin unsigned int types.
2443 Remove 2 #includes. They cause errors (on Sony, at least),
2444 and aren't needed (they wern't in earlier versions).
2446 print_address_symbolic should never demangle labels
2447 (since it prints *assembler-level* labels).
2449 [This was superseded by the change to printcmd below.]
2452 Add some "volatile" return types to avoid warnings.
2453 If MISSING_VPRINTF add vprintf function and not just macro
2454 (since vprintf is used in printcmd.c).
2456 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2457 (The latter isn't grokked by some PCC-based compilers.)
2459 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2461 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2462 * nindy-share/coffstrip.c
2463 Added some forward declarations (otherwise, gcc complains
2464 about implicit extern redefined as static).
2466 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2468 Changes inspired by Per Bothner:
2469 * printcmd.c (print_address_symbolic): Take additional parameter
2470 specifying whether to demangle.
2471 (print_address): Pass in asm_demangle to control demangling.
2472 (print_address_demangle): New fn, takes explicit arg to control
2474 * utils.c: Add new vars demangle and asm_demangle, and let them
2476 (fputs_demangled): If !demangle, just print the argument.
2477 (fprint_symbol): If !demangle, just print raw symbol.
2478 * valprint.c (val_print): Call print_address_demangle rather than
2479 print_address, to cause demangling to depend on the global
2480 rather than assembler-level demangling setting.
2481 * WHATS.NEW, gdb.texinfo: Document.
2483 * main.c (show_command): Show all settings if no arg.
2484 (initialize_main): Make "info set" the same as naked "show".
2485 * command.c (cmd_show_list): Handle prefix commands in the
2486 list, and print the name of the setting as well as its English
2487 description and value.
2489 Allow gdb functions to specify where a line should wrap if it
2490 exceeds the size of a terminal line. Use it to make the output
2492 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2493 of the right size when screen width changes.
2494 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2495 (wrap_here): New fn, indicates a point in the output where we
2496 should wrap the line rather than just letting it overflow at a
2498 (fputs_filtered): Implement wrapping.
2499 (n_spaces): New fn, returns a pointer to N spaces.
2500 (print_spaces_filtered): Use n_spaces.
2501 * defs.h (n_spaces): Declare.
2502 * stack.c (print_frame_info): Wrap with 4-space indent after
2503 fn name and before filename and line number.
2504 * printcmd.c (print_frame_args): Wrap with 4-space indent
2505 before each argument name is printed.
2506 * valprint.c (value_print): Wrap with no indentation before
2508 (val_print_fields): Wrap with indentation relative to nesting
2509 level before each field name.
2510 (val_print): Wrap with nesting indentation before array elements.
2511 * command.c (do_setshow_command): Avoid extra newlines,
2512 wrap with 4-space indent around values printed, end with period.
2513 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2515 * breakpoint.c (breakpoint_1): Implement addressprint for
2516 "info breakpoints" display. Change file name and line number
2517 format to " at file:nnn" rather than " (file line nnn)".
2518 * gdb.texinfo: Document.
2521 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2523 Frozen for gdb-3.92.6 release.
2525 README, WHATS.NEW: Update for 3.92.6 release.
2527 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2528 coffread.o from configs since it is now built by default.
2529 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2530 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2531 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2532 from configs since it is now built by default.
2534 Makefile.dist: Update for release 3.92.6. Handle files that
2535 have been moved to ../include, ../getopt, or ../bfd. Add
2536 saber.suppress and tests directory. Add config.status to
2537 the release (it will say "none").
2539 coredep.c: Minor formatting fixes.
2541 These changes were made in early December but only checked in now:
2542 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2543 nindy-share/nindy.c: lint
2544 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2545 register values coming back from the target; we store values
2546 in target byte order everywhere.
2548 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2550 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2552 * valprint.c (cplus_val_print, val_print_fields): New functions,
2553 which print C++ objects. They conspire to avoid printing a
2554 virtual base class more than once, following all the twists and
2555 turns of C++ virtual base rules.
2556 (val_print): Call the above rather than do it by hand.
2558 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2559 symbol file, not for added files like shared libs. This really
2560 needs to be generalized to a timestamp per file.
2562 * core.c (cleanup_core): Avoid coredump if no core file.
2564 * config.gdb: Accept -host or -target in place of +host or
2567 * coffread.c (find_linenos): Avoid desupported BFD interface
2568 to line numbers. We still read them manually rather than using
2569 BFD's "generic" features.
2571 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2573 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2575 * Makefile.dist: Eliminate use of $< in explicit targets.
2577 * readline/Makefile: Use $< rather than $*.c, which does not
2578 include the VPATH in GNU Make.
2580 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2581 copies of tconfig/i960, added for global configuration
2582 compatability. All i960 versions can read both coff and b.out.
2584 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2585 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2588 * TODO: Think of more things to do.
2590 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2592 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2593 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2594 64-bit float conversion.
2596 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2597 equivalent to sun?os4 so global config works.
2599 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2601 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2603 * main.c: Only declare linesize once; declare pagesize not at
2604 all, since it is never used.
2605 (main): Clear newly allocated line before it is used.
2607 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2609 Further stabilization for the Intel 960.
2611 * Makefile.dist: Parameterize the location of the "include"
2612 and "bfd" directories, as well as "getopt". Add symfile.c.
2613 Link in both dbxread and coffread. Fix up "make depend" to
2614 rewack the locations of include, bfd, and getopt in its output.
2616 * README: Document moving include files, improve some of
2619 * coffread.c: Move common code out to symfile.c. Change
2620 symbol_file_command style interface to use new *_symfile_init
2621 and *_symfile_read interface under BFD. Use BFD internal
2622 info to locate line table, symbols, etc.
2624 * core.c (core_fetch_registers): Rename to get_core_registers
2625 to avoid confusion with fetch_core_registers.
2626 (register_addr): Move to coredep.c, which is already machine
2627 dependent. This leaves core.c pretty clean of dependencies.
2629 * coredep.c (register_addr): Accept this routine from core.c.
2631 * dbxread.c: Move common code (with coffread.c, etc) into new
2632 symfile.c. Each psymtab now contains a pointer to the
2633 format-dependent function that knows how to read it in. Make
2635 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2636 (process_one_symbol): Add code to complain about a "compiler bug
2637 we muzzle here", if we actually see it.
2639 * eval.c (evaluate_subexp): Insert missing "break" statements
2640 in code that determines whether a variable is an lvalue in
2641 memory, register, or whatever. I detected this via a compiler
2642 bug in which it *almost* mashed out the whole switch statement.
2644 * gdb-int.texinfo: Add minor sections on configuring gdb for
2645 release, and about the README file.
2647 * infcmd.c (registers_info): Fix formatting somewhat. Still
2648 not as pretty as before, but it handles byte swapping.
2650 * remote-nindy.c: If data cache routines are interrupted while
2651 waiting for the remote end, be sure that any uninitialized cache
2652 blocks are on the free list, not on the valid list!
2654 * symfile.h: Flesh out this header file with all the various
2655 routines and variables that have been merged in from dbxread.c
2656 coffread.c, and symtab.c to symfile.c.
2658 * symfile.c: New file, containing code common to dbxread.c,
2659 coffread.c, and some code from symtab.c. All generic code for
2660 reading symbol files should be in here now.
2661 (unrecord_misc_function): Remove unused function.
2663 * symtab.h: Remove file-reading things to symfile.h.
2665 * symtab.c: Remove file-reading things to symfile.c.
2667 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2668 to decode i960 fault types.
2670 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2671 target.c: Change type of the "resume" function from int to void,
2672 since its result was never used.
2674 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2676 * main.c: Replace "stupid" with "caution"; you now "set caution
2679 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2681 * infcmd.c (do_registers_info): Call val_print to deal with the
2682 byte order of the registers being printed. FIXME, this makes
2683 the formatting of the output uglier.
2685 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2686 defined, call it for signals the debugger doesn't itself use.
2687 The i960 uses this for more detailed fault information.
2689 * remote.c (remote_open): If arg is null, print help rather than
2692 * sparc-xdep.c (register_valid): Avoid declaring size, since
2693 various modules will think of various sizes depending on the
2694 architecture of their tm-file. FIXME, we need protection against
2695 actually entering one of those modules, which would clobber
2696 storage if not for the target architecture compiled into gdb.
2698 * stack.c (up_command, down_command): Always print the frame
2700 (up_silently_command, down_silently_command): New commands
2703 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2705 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2706 more parameters than it used to.
2708 * findvar.c (registers): Increase slop to 256 bytes, which should
2709 protect us against even most RISC machines with large register
2711 (locate_var_value): Move declaration inside related ifdef.
2713 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2714 throughout, to avoid throwing away buffered input from the board.
2715 (nindy_wait): Supply_register takes addr_of_value, not value.
2716 (i960_print_fault): Renamed from i80960_fault.
2717 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2718 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2720 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2721 we can set the PC in the call to proceed(). Unpush nindy_ops
2722 before pushing it on top, to avoid message to user. Eliminate
2723 commentary from Unix machines that just misleads here.
2724 (reset_command): Fix error message to suggest target command.
2726 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2728 Release 3.92.5 as frozen.
2730 Stabilize the merged release...with help from lint, Saber C,
2733 Everywhere: Add include files needed to declare return types
2734 of functions called.
2736 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2738 * breakpoint.h: Add undeclared breakpoint functions, and some
2739 functions for display handling since I couldn't think of a better
2742 * breakpoint.c (insert_breakpoints): Make code for disabling
2743 shared library bkpts more likely to work. It's used when we
2744 rerun a program and stop before the shared library has been
2746 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2747 cast from pointer, so it squeezes through catch_errors.
2748 (bpstat_stop_status): Fix logic broken some time ago. We now
2749 always create a bpstat if the stop address matches a breakpoint,
2750 even if we don't stop there -- just like the old code used to do
2751 before I got my fingers into it (sigh).
2752 (breakpoint_1): Print "ignore count" after "stop only if"
2753 condition, since that's how it actually works.
2754 (mention): Handle watchpoints as well as breakpoints.
2755 (watch_command): use set_raw_breakpoint and mention to do most
2756 of the work (and initialize all the fields!). Only pass one
2757 arg to parse_c_expression, since that's all it takes.
2759 * command.c (not_just_help_class_command): Rename arg to args
2760 since we ignore "unused argument" warnings on vars named "args".
2761 inflow.c (child_terminal_info): ditto.
2762 infptrace.c (kill_inferior): ditto
2763 main.c (catch_errors, version_info, quit_command, pwd_command,
2764 source_command, dump_me_command, editing_info,
2765 set_history_size_command, set_history, show_history,
2767 stack.c (locals_info): ditto
2768 target.c (target_files_info): ditto
2769 valprint.c (set_input_radix, set_output_radix): ditto
2771 * core.c: Remove old variables for handling core and exec file
2772 sections (data_start, data_end, stack_start, stack_end,
2773 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2774 text_end, exec_data_start, exec_data_end, text_offset,
2775 exec_data_offset, data_offset, stack_offset). They're
2776 superseded the more general build_section_table and
2778 (get_exec_file): Mention the `file' command.
2779 (read_memory_check): Rename to memory_error, and only call it
2780 in the case of an actual error.
2781 (read_memory, write_memory): call memory_error.
2782 (core_fetch_registers): Register section name is ".reg".
2784 coredep.c: Remove a bunch of crud now that all this file does
2785 is pull the registers out of a core file.
2786 (fetch_core_registers): Rewrite to actually work, I hope.
2788 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2789 Replace index() with strchr(). Remove all the pre-BFD macro
2790 definitions for accessing the symbol file.
2791 (struct dbx_symfile_info): Encapsulate the information that
2792 dbx_symfile_init needs to pass to dbx_symfile_read in this
2795 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2796 dbx_symfile_discard): Rearrange symbol file reading to divide
2797 the format-specific part from the format-independent part,
2798 leaving the format-independent part such as file name expansion
2799 and opening in symtab.c. This replaces
2800 partial_symbol_file_open and partial_symbol_file_read.
2801 Symbol_file_read, add_file, add_file_target_command,
2802 add_file_addr_command move to symtab.c. Pass an explicit
2803 "mainline" flag for when reading the main symbol table, rather
2804 than relying on the offset address to be zero or nonzero.
2806 (dbx_symfile_read): Don't allow void *'s to be printed as
2808 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2809 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2810 macro" debug version really work.
2811 (read_dbx_symtab): Remove unref'd parameter inclink.
2812 Avoid swapping N_SLINE symbols, for speed.
2813 Merge N_TEXT!N_EXT case with the other external symbol
2814 definitions' case. Add comments.
2815 (start_psymtab): Allocate the symfile name in the psymtab on
2816 the psymbol_obstack, rather than using the caller's storage.
2817 (end_psymtab): Only allocate a dependencies list if there are
2819 (psymtab_to_symtab_2): Use BFD when reopening file to read
2820 its symbols for real.
2821 (read_struct_type): Add FIXME comments where it needs work
2823 (read_huge_number): Add FIXME about overflows.
2824 (read_range_type): Add FIXME about comparing a long to 1<<32.
2826 * coffread.c: Minor changes to move things closer to the new
2827 regime with symtab.c and dbxread.c Major work is still needed
2830 * exec.c (exec_file_command): Remove old variables (see core.c
2832 (xfer_memory): If memory transfer is right at the end of a
2833 section, don't lose.
2835 * findvar.c (get_saved_register): If value is in a real
2836 register, LVAL is lval_register, not lval_memory.
2838 frame.h: Declare print_sel_frame and record_selected_frame.
2840 gdb-int.texinfo: New file, for GDB internals documentation.
2841 Very simple, unformatted doc of cleanups is there for now.
2843 gdbcore.h: Remove obsolete variables that described a.out
2844 section addresses and offsets. (See core.c above.)
2845 Declare fetch_core_registers and registers_fetched.
2847 getopt.c: Declare char *alloca(); even on SPARC.
2849 infcmd.c (run_command): Call target_kill rather than
2851 (step_command, next_command, stepi_command, nexti_command):
2852 Declare from_tty parameter even though we don't use it.
2853 (run_stack_dummy): argument BUFFER is a char array, not
2854 a pointer to REGISTER_TYPE.
2855 (finish_command): using_struct_return needed a value *,
2856 not a struct symbol *.
2858 * infptrace.c (child_xfer_memory): To avoid dependency on
2859 where sections are in memory, try PT_WRITE_D and if that fails,
2860 try PT_WRITE_I. Most Unixes don't care which you use.
2862 * infrun.c (step_resume_break_shadow): Change to array to
2863 match other breakpoint shadow storage.
2864 (clear_proceed_status): Pass address of bpstat to
2865 bpstat_clear, not the bpstat itself.
2866 (child_create_inferior): FIXME comment about if the child
2868 (start_inferior): Remove old function.
2869 (child_open): Use target_kill rather than kill_inferior.
2870 (wait_for_inferior): Ditto.
2871 (insert_step_breakpoint, remote_step_breakpoint): Use
2872 new step_resume_break_shadow.
2874 * inftarg.c (child_wait): If all child processes die,
2875 pretend that the one being waited for exited with signal 42.
2877 * main.c (command_line_input): When scanning for comments,
2878 don't coredump on unclosed quotes.
2879 (quit_command): Use target_kill rther than kill_inferior.
2880 (_initialize_main): Rename class_user from "user" to
2883 * printcmd.c (print_command_1): Initialize "fmt" if no format
2884 is specified by the user.
2885 (print_frame_args): Only add to args_printed if we are
2886 actually fetching args from the stack (avoiding undefined
2888 (_initialize_printcmd): Remove bogus \{ from string.
2890 * remote-eb.c (eb_open): Avoid coredump on no argument.
2892 * remote-nindy.c: Bring out of Intel environment into new
2893 target environment. Remove all conditional compilation on
2894 I80960. Massive hacking throughout.
2895 (nindy_xfer_inferior_memory): New routine stolen from
2897 (nindy_create_inferior): New routine pieced together, probably
2898 not quite working yet.
2899 (nindy_ops): New target_ops struct for nindy.
2901 * remote-vx.c: Use write_memory rather than target_write_memory
2902 to get error checking.
2903 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2905 (vx_create_inferior): Use target_terminal_ours...
2907 * signame.c (_initialize_signame): Always initialize, since
2908 we need the table for things other than psignal.
2910 * solib.c (solib_add): Use symbol_file_add, not add_file.
2911 (solib_address): Return boolean result rather than struct
2912 pointer which nobody else knows the type of.
2914 * sparc-tdep.c, valops.c: Use write_memory rather than
2915 target_write_memory, to get error checking.
2917 * stack.c (locals_info, catch_info, args_info,
2918 get_selected_block, frame_command, up_command): Use
2919 target_has_stack, rather than have_inferior_p or
2922 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2924 * symfile.h: New file, defining the interface between the
2925 generic and object-file-specific symbol reading code.
2927 * symtab.c: Move generic symbol-reading interface to symtab.c,
2928 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2929 table to map BFD targets to symbol-reading modules in GDB.
2930 Change index to strchr.
2931 (lookup_struct_elt_type): Use error() rather than hand-made
2932 simulations thereof.
2933 (lookup_partial_symbol): Speedup slightly when length == 0.
2934 (symbol_file_add): New function.
2935 (symbol_file_command): Call it.
2936 (symfile_open, symfile_init): New function.
2937 (add_file_target_command, add_file_addr_command): moved from
2940 * target.c (target_command): use target_kill.
2942 * target.h (target_files_info): Don't declare, never called
2945 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2946 files to determine stack end address.
2948 * valarith.c (value_x_binop, value_x_unop): Change error message
2949 to be more useful. Pass proper argument to value_struct_elt.
2951 * valops.c (value_assign): FIXME comment that long long
2952 bitfields will break here.
2954 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2955 Update `make saber_gdb' to work better.
2957 * TODO: A woman's work is never done.
2959 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2960 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2961 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2962 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2963 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2964 valops.c, valprint.c, exec.c: Lint.
2967 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2969 Continuing Intel 960 port merge of GDB.
2971 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2972 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2973 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2974 Wack over "make depend" so it handles files in subdirectories
2975 vx-share, nindy-share, bfd, and in the current directory.
2977 * blockframe.c (get_prev_frame_info): Remove fatal error
2978 if stack not defined.
2980 * core.c (core_open, core_detach): New functions that handle
2981 the old "core-file" command as "target core" and "detach" instead.
2982 (core_file_command): Call them.
2983 (core_xfer_memory): Use common routine xfer_memory.
2985 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2986 dbxread now uses bfd for everything but symbol reading itself.
2987 BFD internals are used to drag out the relevant file offsets.
2988 (partial_symbol_file_open): Change args all around for BFD.
2990 * symtab.c: Rename "value" to "val" everywhere, so we can
2992 (symbol_file_command): New command, moved from dbxread.c
2993 and coffread.c. It uses BFD to read the file, then vectors
2994 based on its type, to dbx or coff symbol readers.
2995 * symtab.h: Extern a few vars for symbol_file_command.
2997 * target.h: Breakpoint takes a char * save area, not a char **.
2999 * valprint.c (val_print): When unpacking bitfields, offset
3000 the address in gdb of the value, if it is declared with a shorter
3001 type. Remove the last "runtime kludge test" of host byte order.
3003 * utils.c: Remove old my_bfd_read routine.
3005 * stack.c (frame_info): Use target_has_stack. Print program counter
3006 register's actual name rather than "pc", since it's called the
3007 "ip" (instruction pointer) on the i960 (sigh).
3009 * target.c (target_command): Add command for selecting a target
3010 type and calling its open routine. This is used for initiating
3011 communication with a particular target, in a generic way.
3013 * tm-i960.h: Update for modern gdb. Remove semicolons from
3014 various macros. Handle reading struct return convention, and
3015 error-out attempts to return structs with the "return" command.
3016 Be sure gdb doesn't think we know how to call functions in the
3019 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
3020 to i960_xxx in lower case.
3021 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
3022 not being defined yet.
3024 * remote.c (remote_open): Call start_remote to initialize
3025 wait_for_inferior during open.
3026 (remote_xfer_inferior_memory): Return length written rather
3029 * remote-vx.c (target_command -> vx_open): Use new generic
3031 * remote-eb.c, inftarg.c, exec.c: ditto.
3033 * infrun.c: Fix comments.
3034 (attach_program -> child_open): Use new generic target command.
3035 (wait_for_inferior): Clear saved register values before target_wait,
3036 so target_wait can set some of them if convenient.
3038 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
3039 Return success indicator, not void.
3040 (child_xfer_memory): Avoid fetching initial word if we'll
3041 overwrite it anyway.
3043 * infcmd.c (attach_command): Use new generic target open routine.
3044 (_initialize_infcmd): Update doc on attach and detach commands.
3045 (do_registers_info): Merge in a byte-order problem as a FIXME
3048 * findvar.c (find_saved_register): Avoid problem in current frame.
3049 (read_relative_register): Ditto.
3050 (write_register): Convert byte order on the way out.
3052 * exec.c (file_command): Add.
3053 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
3054 (xfer_memory): Common function between core_xfer_memory and
3056 (exec_xfer_memory): Use it.
3058 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
3060 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
3061 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
3062 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
3064 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
3066 Merge Intel 960 port of gdb, continuing...
3068 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
3069 symbol_file_command): Pass from_tty arg to hush 'em up.
3071 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
3072 Add magic numbers for 960 COFF format.
3074 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
3076 Merge Intel 960 port of gdb, from Intel "1.2" release.
3078 CHANGE_LOG entries from their port, which was based on
3081 Thu Sep 6 11:02:22 PDT 1990
3082 Remove temp file if download is interrupted.
3084 Wed Aug 1 09:08:33 PDT 1990
3085 Now uses binary protocol to talk to NINDY.
3086 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
3087 Times out after 5 seconds when trying to talk to NINDY.
3089 Tue May 29 12:54:49 PDT 1990
3090 Added variable baud rate (-b switch).
3091 Source code reorganization.
3093 Thu Apr 26 11:09:55 PDT 1990
3094 More cleanup of batch mode; specifically, execute "-s", "-e", and
3095 "-se" switches as soon as they are encountered on the invocation line.
3097 Fri Apr 20 13:47:15 PDT 1990
3100 Thu Apr 19 09:54:28 PDT 1990
3101 Add 'reset' command.
3103 Wed Apr 18 09:48:07 PDT 1990
3104 After opening remote tty, wait for 1 second to go by without input
3105 from it before trying to talk to NINDY (fixes problems with the
3106 Heurikon HK80/V960E).
3108 Mon Apr 4 16:33:05 PDT 1990
3109 Some output was not being suppressed in 'batch' mode.
3111 Thu Mar 22 15:31:11 PST 1990
3112 Ask user if old symbol table should be deleted when new file is
3115 Allow user to run a program downloaded before gdb960 was brought up.
3117 Correct "exec-file" help message for i80960 context.
3119 Correct bug in calculating user space address: could occasionally
3120 corrupt user program.
3122 Make sure to zero low-order bits in rip's because of bug in 960CA
3123 A-step part: could cause operation faults when "next"ing across
3126 Correct bug that made it impossible to get source line numbers for
3127 code loaded at addresses higher than 0x7fffffff.
3129 Wed Jan 10 12:43:22 PST 1990
3130 Open remote tty for exclusive use.
3132 Fri Jan 5 12:14:42 PST 1990
3133 Correct disassembly (CA manual was right after all):
3134 opcode for sysctl is 0x659
3136 Mon Oct 23 12:03:04 PDT 1989
3137 Use G960BASE and G960BIN environment variables to find 'sx' utility.
3139 Mon Oct 16 14:15:09 PDT 1989
3140 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
3142 Mon Oct 2 15:56:31 PDT 1989
3144 Added 960CA disassembly support.
3146 To simplify maintenance:
3147 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
3149 - eliminated opcode.h: incorporates tables into i960-pinsn.c
3150 - moved 960-specific routines from i960-pinsn.c to i960-md.c
3151 - made disassembly interface identical to that in gdmp960.
3155 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
3157 * target.h: Allow targets to stack. Add target_has_memory,
3158 _registers, etc. Restructure memory access and "info files"
3159 to walk the target stack.
3160 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
3161 target.c: Change tables to match target.h.
3162 * inflow.c (child_mourn_inferior): pop child_ops.
3163 (generic_mourn_inferior): Use new has_stack flag.
3164 * infptrace.c (child_xfer_memory): New memory regime.
3165 * inftarg.c (child_files_info): New "info files" regime.
3166 * remote-eb.c: New memory regime, new info files.
3167 * remote-vx.c: New memory regime, new info files. Now use
3168 separate targets for VxWorks attachment to machine, and
3169 actually running a process under VxWorks, since one has
3170 stack & execution & regs and the other doesn't.
3171 * remote.c: New memory regime, new info files.
3172 * sparc-xdep.c (fetch_core-registers): New memory regime.
3173 * target.c: New routines and support for stacked targets,
3174 new memory regime, new info files regime.
3177 Generalize section handling for an arbitrary number of sections,
3178 including use of the new BFD (binary file) library.
3179 * gdbcore.h: Add struct section_table.
3180 * exec.c (build_section_table): Iterate all sections and
3181 record what gdb needs to know about them.
3182 (exec_command): Use it.
3183 (exec_xfer_memory): Use the table.
3184 (exec_files_info): Print the table.
3185 * core.c (core_file_command, core_xfer_memory, core_files_info):
3187 * source.c (find_source_lines): Use bfd_get_mtime.
3188 * dbxread.c: Quick changes to make it compile with new BFD.
3189 * utils.c (error): Avoid using bfd_error in generic routines.
3191 * core.c (core_fetch_registers): Get from the ".regs" section of
3193 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
3195 * inferior.h (attach_flag): Export.
3196 * infcmd.c (run_command): use new target_create_inferior.
3197 * infrun.c (child_create_inferior): Don't return result.
3198 * Makefile.dist (VERSION): 3.91.4.
3200 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
3202 * breakpoint.c (bpstat_num): Handle breakpoints which have
3203 since been deleted, such as temporary breakpoints.
3204 infcmd.c (program_info): ditto.
3206 * core.c (core_file_command): Display the frame where the core
3211 * remote-vx.c (target_command): Merge in target command from
3212 targ-vx.c. A few other cleanups.
3214 * TODO, Projects: Lots more stuff to do...
3216 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
3218 Massive changes to wall off the remote-debugging interface
3219 behind a function vector. The port to handle VxWorks targets
3220 is also part of this.
3222 All files: Replace references to renamed functions,
3223 remove references to remote_debugging, remove references to
3224 have_include_file, have_core_file in favor of target_has_stack,
3225 target_has_memory, etc.
3227 * Modularize the breakpoint interface.
3228 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
3229 a breakpoint instruction.
3230 breakpoint.c: struct breakpoint's shadow_contents now sized as
3232 (insert_breakpoints): Vector to target to install breakpoints.
3233 (remove_breakpoints): Vector to target here too.
3234 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
3235 sparc-tdep.c (single_step): Use new breakpoint interface for
3236 the single-step breakpoints.
3237 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
3238 New file, contains routines to insert and remove breakpoints by
3239 reading out the old contents and later replacing them. This is
3240 how ptrace breakpoints work, and many remote systems as well.
3242 * tm-vxworks68.h: New config file, overrides a few things for
3243 Wind River's preferences.
3245 * target.h: New file, for transfer vector used to talk to the
3246 inferior (child, attached, core, exec, remote, etc). All accesses
3247 to the thing being debugged should come through these vectors.
3248 target.c: New file, routines to handle transfer vector.
3249 (various files): Add transfer vectors XXX_ops for the various
3250 targets and pseudo-targets (core files, etc) we support.
3252 * breakpoint.c (bpstat_stop_status): Further explorations of
3253 watchpoints and why things don't work all the time.
3254 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3256 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3257 the local gdbinit if it doesn't already have it.
3259 * core.c (core_ops): add and install.
3260 Allow core debugging without exec file.
3262 * dbxread.c (free_and_init_header_files): Merge two fns.
3263 (end_symtab): Free named symbol table when a new version comes in.
3264 (read_dbx_symtab): Relocate all kinds of symbols with base
3265 address. First step toward handling different text, data, bss
3267 (add_file_addr_command): Renamed add_file_command.
3268 (add_file_command): Vector to remote handler.
3269 Add "load" as an alias for "add-file" command.
3271 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3272 non-returning functions.
3274 * exec.c: Add exec_ops, and push it as a target when an exec
3277 * infcmd.c (run_command): Pass executable file name and arg list
3278 separately when starting an inferior. Permit "run" when no exec
3279 file is specified, for VxWorks.
3280 (detach_command): Move to child_detach in inftarg.c.
3282 * inftarg.c: New file. Unix-child-specific routines, and the
3283 child_ops structure.
3285 * inferior.h (registers): Export "registers" as the way for
3286 target dependent register handlers to find gdb's local copy of
3287 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3288 since it is now used by places that want wait_for_inferior to
3289 handle the grunge but want to see every trap from the inferior.
3291 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3292 Eliminate remote_debugging hooks in terminal handling.
3294 * infrun.c: Replace start_inferior with child_create_inferior.
3295 Move all the hair of Unix shells and ptrace idiosyncracies into
3296 child_create_inferior, so remote handlers don't have to deal.
3297 Remove running_in_shell. Rename stop_after_attach to
3298 stop_soon_quietly, and use it in a few other places where we want
3299 to just call wait_for_inferior and get control back on the first
3300 trap. trap_expected now never takes a value > 1.
3301 (init_wait_for_inferior): Initialize static vars when a new
3304 main.c (gdbinit): Add new hook for .gdbinit file name, let
3305 it be overridden by config files as GDBINIT_FILENAME.
3306 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3307 Both of these are used for VxWorks gdb.
3309 mcheck.c: rename include file "gmalloc.c" to avoid problems
3310 with system include file "malloc.c".
3312 param-no-tm.h: New include file, same as param.h but does not
3313 include the default "tm.h" file. This is used in files where
3314 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3316 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3318 remote-vx.c: New file, VxWorks remote debugging support. Uses
3319 RPC routines that are shared with the target system, in directory
3322 remote.c: Vectorize remote interface.
3324 source.c: Globalize source_path, and make an alias "l" for "list"
3325 since we now have the "load" command.
3327 sparc-xdep.c: Use new param-no-tm.h.
3329 symmisc.c (free_named_symtab): Add new function from Wind River.
3330 However, ifdef it out for now while we think about what it should
3333 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3335 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3336 non-Unix-children handle this with their own code in the target
3339 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3340 source and target lists. Add vx-share to default list of include
3341 directories. Add new files to src and target lists: mem-break,
3342 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3343 ${srcdir} versions of munch and createtags are used.
3345 * valops.c (find_function_addr): Split out of call_function.
3346 (call_function_by_hand): Rename call_function; this function
3347 calls functions in the target by laboriously patching the target
3348 word-by-word with the right stack, args, regs, etc.
3351 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3353 Handle AMD 29000 a bit better.
3355 * remote-eb.c (readchar): Mask received char log to make it readable.
3356 (remote_start): Pass arguments down to executing program.
3357 Make startaddr unsigned.
3358 infrun.c (start_inferior): Accept args, pass them to
3360 infcmd.c (run_command): Pass args down to start_inferior.
3362 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3363 the target object file format.
3364 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3366 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3367 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3369 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3371 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3372 * TODO: We did a few things, we have more to do though.
3374 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3375 * inflow.c (inferior_died): Clear deferred stores.
3377 * Debug problems with dummy frames and calls to the inferior.
3378 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
3379 * sparc-tdep.c (do_restore_insn): Simplify.
3380 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3381 (sparc_push_dummy_frame): Simplify and fix what we push.
3382 (sparc_pop_frame): Slightly more hair here, deciding whether
3383 we are restoring a saved PC or returning to a return address in %i7.
3384 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3386 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3387 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3388 * obstack.h (chunkfun): ditto.
3389 * defs.h (xmalloc, xrealloc): ditto
3391 * utils.c (quit): Grab the terminal from the child if necessary.
3393 * inflow.c (term_status_command): Rename to term_info, change
3396 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3397 (is_delayed_branch): Speed up.
3398 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3399 Still missing some float ops, and needs testing.
3401 * Support for input and output radixes other than base 10
3402 * defs.h (input_radix, output_radix): Declare.
3403 * expread.y (yyparse, parse_number): Handle changes of input
3404 radix, and ambiguous names-or-numbers in radixes >10.
3405 * printcmd.c (print_scalar_formatted): Print formatted hex
3406 numbers in varying column widths.
3407 * valprint.c (val_print): Use output_format to print scalar ints.
3408 (set_input_radix, set_output_radix, set_radix): Create.
3409 (set_output_radix): Set output_format from output_radix.
3410 (_initialize_valprint): add `set radix' but leave the others off.
3412 * main.c (execute_command): Let stupid questions be turned off.
3413 (_initialize_main): Handle "set stupidity", etc.
3415 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3416 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3418 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3420 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3421 bfd stuff is still screwed up, but with some manual work, it
3424 * breakpoint.c (bpstat_do_actions): Start over if a command
3425 proceeds the inferior, since the inferior will have stopped and
3426 will need to have its new stop-actions taken care of.
3428 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3429 compiler fits, simplify it.
3431 * gdb.texinfo (directory command): Doc new dir command.
3432 source.c (directory_command): "dir" now puts things on the front
3433 of the path, moves dups up front, and handles multiple names
3434 on the command line, inserting each one in order. It also
3435 blows away cached line and full_filename info.
3437 * stack.c (backtrace_command): Skip "more stack frames follow"
3440 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3441 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3442 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3443 The only odd one was Gould NP1, which had defined vprintf to
3446 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3447 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3448 variable, inspect_it.
3449 valprint.c (print_string, val_print): Use the global inspect_it
3450 to indicate whether to print in Epoch style or normal style.
3452 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3454 * printcmd.c (call_command): add an alias for the "print" command
3455 which runs expressions and doesn't print the result if void.
3456 (print_command_1): implement it.
3458 * command.c: Remove #if 0'd code. Initialize all the fields
3459 in add_cmd (). Rename do_nothing_command to
3460 not_just_help_class_command, and make it externally visible.
3461 command.h: add user_commands to struct.
3462 * main.c (define_command): Don't overload c->function with a char
3463 string as well as a function pointer.
3465 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3466 calling convention of value_struct_elt () that got dropped in
3469 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3470 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3472 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3474 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3475 until a good time (e.g. when we are about to run the child),
3476 saving ptrace calls.
3477 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3478 * tm-sparc.h: define DO_DEFERRED_STORES.
3480 * sparc-xdep.c (store_inferior_registers): when storing float
3481 registers, don't store stack regs too. When storing the SP,
3482 however, DO store the stack regs too. This fixes a bug in which
3483 the dummy frame is not recognized when a call_function finishes,
3484 because its frame pointer (in the stack regs) was never
3486 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3487 even though we don't know how to read them from an inferior.
3488 valops.c (call_function): Comment about storing SP.
3490 * infrun.c (save_inferior_status): Save away the original bpstat
3491 chain so it can be restored later. Install the copied version for
3492 use by whoever saved the status. It will be blow away by
3493 restore_inferior_status, and the original chain restored. This is
3494 important for people who have pointers into the original.
3496 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3497 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3498 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3501 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3503 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3504 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3505 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3507 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3509 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3510 Store the baseclasses in a type struct starting from array element
3511 0 rather than from the unusual array element 1.
3513 dbxread.c: the above.
3514 (virtual_context): Add
3515 Read new debug information about which virtual function table
3516 a virtual function is from, and store it in fn_field.fcontext.
3518 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3519 TYPE_FN_FIELD_STATIC_P.
3521 symtab.c: the above.
3522 valops.c: the above. Handle pointer casts of object *'s.
3523 (search_struct_method): Add.
3524 (value_struct_elt): First arg is now a pointer to a value, and is
3527 valprint.c: the above.
3528 values.c (value_virtual_fn_field): Add type arg. Handle
3529 offsetting to the proper object when calling virtual fns.
3531 (baseclass_addr): Add valuep arg.
3533 * README: Document the current state of BFD config (missing).
3534 * TODO, ChangeLog, Makefile.dist: Roll version.
3535 * WHATS.NEW: Add summary of changes since 3.5.
3537 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3539 * dbxread.c (read_struct_type): Clear bit vectors whenever
3541 symtab.c (B_CLRALL): define.
3543 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3544 using == rather than =. Huh... This fixes the dreaded problem
3545 wherein builtin_type_int becomes TYPE_CODE_FLT.
3547 * core.c (info_files): Show the inferior pid.
3549 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3550 already knows how to look in the source directory.
3552 * Remove psymtab hair from many places. Remove duplicated code
3553 for searching symbol tables. Hide psymtabs from most places.
3554 Make it fast to get from a psymtab to its symtab.
3556 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3557 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3558 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3559 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3560 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3561 new symtab completely. New psymtabs get symtab pointer
3562 initialized to zero. Remove MI warning printf.
3563 symtab.h: Comments. Add psymtab to symtab pointer.
3564 (PSYMTAB_TO_SYMTAB): New macro.
3565 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3566 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3568 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3570 (print_frame_info): Avoid special-casing symbols that have not yet
3573 * source.c (open_source_file): Quick path if we have already
3574 located the source file by its full name.
3576 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3577 find_pc_psymtab. When a name is found in the misc function
3578 vector, search the symbol table for its mangled name, not the
3579 name that the user typed.
3581 * bfd.h: Fix missing comment terminators, make #endifs match.
3583 * valarith.c (value_less): Handle unsigned int comparisons.
3584 Add FIXME about pointer compares, which assume host and target
3585 pointers are the same.
3587 * command.c (do_nothing_command): lint
3588 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3589 fix comments on debug symbol format for visibility. Actually set
3590 visibility of symbols.
3591 main.c (echo_command): lint; use <readline/history.h>.
3592 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3593 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3594 pointing past end of allocated memory; saber complains.
3595 obstack.h: Declare the external functions that we use.
3596 valarith.h: use <string.h>
3597 solib.c (solib_add): lint.
3599 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3601 * main.c (initialize_main): Default info_verbose to off, now that
3602 symbol reading is fast.
3603 (quit_command): Avoid clobbering exec_bfd while quitting.
3605 * Initial BFD (binary file diddling library) merger:
3606 coffread.c: Change AOUTHDR to struct exe_hdr.
3608 core.c: initialize initialized data at compile time.
3609 (core_file_command): Move from coredep.c, convert to bfd.
3610 (xfer_core_file): Convert to bfd.
3611 exec.c (exec_file_command): use bfd routines.
3613 mips-tdep.c: Remove exec_file_command and friends.
3616 * coredep.c: (fetch_core_registers) Convert core_file_command to
3617 fetch_core_registers.
3618 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3620 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3621 (my_bfd_read): More bogosity, which I don't think we call.
3622 (program_name): Remove this atrocity asap!
3624 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3627 values.c: allocate_repeat_value was not clearing the
3628 optimized_out field.
3629 (value_static_field): minor stylistic fix (wrong macro was used).
3630 valops.c (value_struct_elt_for_address): didn't work for C++
3633 * signame.c (_initialize_signame): Initialize signal names once.
3635 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3636 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3637 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3639 * remote-eb.c: Support user-settable baud rates on the serial port.
3641 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3643 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3645 * tconfig/sun3os4: Remove warning about native assembler,
3646 since it also occurs in the xconfig file.
3648 * findvar.c (registers): Allocate some slop after `registers'
3649 to prevent stray accesses from trashing the next variable.
3651 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3652 on the sun-3, by changing the #ifdef from `sun3' (which is not
3653 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3654 vars, which happened to follow `registers' in the executable.
3656 * readline/history.c (history_search): Heed gcc-2's advice
3657 and parenthesize && inside ||).
3659 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3660 tm-29k.c: Insert FSF copyright headers.
3662 * remote-eb.c: Better comments.
3664 * Makefile.dist: Update to 3.91.6.
3665 * TODO: note PREPARE_TO_STORE problem.
3667 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3669 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3671 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3673 * infrun.c (wait_for_inferior, at end): Don't set up
3674 prev_* if the inferior no longer exists.
3676 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3677 CANNOT_EXECUTE_STACK.
3678 valops.c (call_function): Use it.
3680 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3682 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3683 infrun.c (wait_for_inferior, 2 places): Use it.
3685 * values.c (value_being_returned): Only use
3686 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3688 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3689 right thing for remote-eb.c.
3691 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3692 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3694 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3695 (FRAME_FIND_SAVED_REGS).
3697 * findvar.c ({fetch,store}_registers): Check for
3698 REMOTE_{FETCH_STORE}_REGISTER macro.
3700 * findvar.c (get_saved_register): Add argument lval and
3701 change meaning of argument addr.
3702 findvar.c: Change calls to get_saved_register to reflect
3703 new calling convention.
3704 valops.c (value_assign): Use get_saved_register instead of
3705 find_saved_register.
3707 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3709 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3710 an (uninitialized) pointer to one. Use "&" when passing it
3713 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3715 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3718 * coffread.c (symbol_file_command): Put semicolon after
3720 Put safe_to_init_tdesc_context in #if defined (TDESC).
3721 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3722 coffread.c: #include <sys/stat.h>.
3723 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3724 Add missing ')' in check for "lc%" and friends. Remove
3726 Declare read_one_sym() at top of file.
3727 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3728 MC68WRMAGIC can have the same value without causing a duplicate
3731 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3733 * Allow a Makefile to be built without building the
3734 tm and xm file links that screw up builds in subdirectories.
3735 This is done with `config.gdb none', then you can do things
3736 like `make gdb.tar.Z'.
3737 * tconfig/none: Config file for no target system
3738 * xconfig/none: Config file for no host system
3739 * config.gdb: If no TM or XM files are called out by the
3740 host or target file, don't make links for them.
3742 * cplus-dem.c: Add documentation.
3744 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3745 simple error, so the user's gdb doesn't crash due to some object
3746 file problem (e.g. somebody is rebuilding the file out from under
3749 * printcmd.c (print_address_symbolic): demangle the symbol.
3751 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3752 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3753 (alldeps.mak): sort and uniq all results from this; duplicates
3754 hose gdb.tar.Z link building. Remove RCS files from
3755 tconfig and xconfig. Add config files for sun386. Add
3756 a few odd files to OTHERS and HFILES.
3758 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3760 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3761 Roll version number to 3.91.5. Make lint work in bindir.
3763 * README: Document cross-debugging and new file structure.
3765 * blockframe.c: Lint. Include "value.h" to declare read_register.
3766 (find_pc_partial_function): remove duplicate line.
3768 * command.h: Lint. Declare error_no_arg and dont_repeat.
3770 * tm-news.h: Remove inadvertently duplicated stuff.
3772 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3773 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3775 * config.gdb: Allow `config.gdb host target' form. Clean
3776 up previous change that printed bogus messages when you just said
3779 * core.c: #include "command.h" for lint.
3782 * main.c: Remove some casts of enums. Lint.
3789 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3791 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3792 read it from memory. This will allow us to save ptrace calls
3793 eventually. Changed caller single_step too.
3795 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3796 that we aren't going to use, saving many ptrace calls, especially
3797 when watchpointing or single stepping. Use some #define's for
3799 (store_inferior_registers): Ditto.
3800 (core_file_command): Use some #define's for constants.
3802 * tm-sparc.h: Add #define's for some register numbers, so we
3803 can eliminate the use of random constants in sparc-xdep.c.
3805 * stack.c (frame_command, print_frame_info, up_command,
3806 down_command) Remove frame_changed, since it
3807 causes a bug and doesn't seem to do anything useful. In some
3808 places it was used as a flag, in others as a stack level (?).
3810 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3811 default is to use the portable (vprintf) version rather than the
3813 * xm-news.h (MISSING_VPRINTF): Add.
3815 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3817 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3819 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3820 about linking debugged programs -Bstatic in the sun?os4 config
3821 files in tconfig and xconfig subdirectories.
3823 * main.c (main): Remove unreached exit(0) now that we exit
3826 * Create TODO file for online bug list. There are too many
3827 "little" bugs to keep track of on paper.
3829 * Change Projects file to refer to bug-gdb@cygnus.com
3830 rather than kingdon@ai.
3832 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3834 * Makefile.dist (VERSION): 3.91.4 now.
3836 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3837 (condense_misc_bunches): Add sanity check that misc_count is
3838 the same as the number of symbols in the bunch.
3840 * coffread.c: rename init_misc_bunches. Pass an argument
3841 to condense_misc_bunches (a zero).
3843 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3844 every time we are called; don't rely on our caller to do it.
3845 (add_file): Remove call to init_misc_bunches.
3847 * mipsread.c: Only warn, don't error, if unknown symbol types.
3848 This keeps an old gdb from falling on its face if it sees newly
3849 extended symbol info. Rename init_misc_bunches.
3851 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3853 * Merge in changes from Per Bothner for DECstations and other
3854 MIPS stuff. The rest is Bothner speaking:
3856 The next message is a merger of Alessando Forin's mips port with
3857 mine. I've tried to use my good if biased judgment to get
3858 the best of both. It *does* need testing.
3860 Some of the changes are general, *not* mips-specific.
3863 Didn't believe in little-endian bit order.
3864 There are still inconsistencies about whether flags
3865 like BITS_BIG_ENDIAN are integer (#if ...) or
3866 boolean (#ifdef ...). I tried to paper over them.
3868 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3869 Moved some misc_function code that was common to
3870 {dbx,coff,mips}read.c to symtab.c.
3871 In the process, I think I cleaned things up a bit.
3872 At the same time, moved obsavestring and obconcat to symtab.c.
3875 Removed obsolete condense_addl_misc_bunches (use
3876 condense_misc_bunches(1) instead).
3879 Needed to include <sys/dir>, at least on DECstations.
3881 valops.c, mips-tdep.c, tm-mips.h:
3882 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3883 conventions (when STACK_ALIGN is insufficient).
3884 Needed on mips, where doubles need 8-byte alignment,
3885 but ints only need 4.
3888 Removed cruft that was not being used.
3889 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3892 Print $ before register-names (I think that makes things a little
3894 Never print two instructions, even if one delays.
3895 Removed hex-disassemble set_cmd. (This is not mips-specific,
3896 so I think the argument is whether it is generally worthwhile or not.
3897 I'm inclined to think not, given how easy it is to
3898 convert between radixes in gdb.)
3901 This is basically Alessando's code.
3902 It doesn't use obstacks; I changed it to use obstacks
3903 in a few minor places where using malloc causes a
3904 memory leak. (Probably, more places could/should be changed.)
3905 I added record_misc_function where it was missing.
3906 In symbol_file_command and add_file_command, I tried
3907 to make the code consistent with more recent versions.
3908 Minor sylistic changes in parse_procedure.
3909 Make a .gdbinfo. psuedo-symbol point back to the real
3910 procedure symbol (using the isym field).
3913 This is basically from my port, but with a lot of details
3914 and a number of routines merged in from Alessando's version.
3915 I basically used my code "raw" backtrace (use heuristics
3916 from the actual code, rather than symbol table info) - though
3917 the idea is Alessandro's. I feel my code is a little cleaner
3918 here, particularly in being a little more flexible, such as being
3919 able to handle gcc-produced code (which it now can).
3920 It also doesn't do frame caching (which is not useful
3921 more recent gdb versions).
3922 I also used my code for push_/pop_dummy, more or less.
3923 I tried to incorporate AF's code for testing sigtramp
3924 while backtracing; I probably got it wrong.
3925 Added mips_print_register, which tries to scrunch as much
3926 information as possible on a screen...
3927 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3928 under mips-pinsn.c), I don't see anything mips-specific here,
3929 and I don't see it being all that useful anyway.
3932 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3933 Use more register names (rather than hard-cases numbers).
3935 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3937 * Hack up 3.90.11 changes:
3939 * Makefile.dist (depend): parameterize $(GCC).
3940 Add solib.c and solib.o.
3941 (readline): Fix vpath for both absolute or relative SRCDIR.
3943 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3944 Also, let the part I didn't understand at least compile so
3945 I can test the rest. FIXME.
3947 * dbxread.c: Fix thinko using strcmp.
3948 (init_psymbol_list): declare static.
3949 (partial_symbol_file_open): Comment cleanups better, avoid
3950 cleaning up the string table since the caller will do that.
3951 Move the stat for mod time into symbol_file_command, temporarily.
3952 (There should be a mod time for each symbol file, eventually,
3953 to control its rereading. FIXME.)
3955 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3956 SunOS, which gives error for shared libs otherwise. (From
3957 Schaefer, probably FIXME needs work for portability.)
3959 * solib.c: Move #include "param.h" to work.
3960 Lowercase all the Uppercase Letters In the Messages.
3961 (find_solib): Clean up inferior_so_name for debug printouts.
3962 Allow no argument, to mean all shared libraries.
3964 * symmisc.c: include param.h to get CLEAR_SOLIB.

3977 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3981 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
3983 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)

3992 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3994 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
3996 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3998 * Changes for Sun shared libraries:
3999 blockframe.c (find_pc_partial_function): If a non-text symbol
4000 is found, set *address = pc - FUNCTION_START_OFFSET.
4001 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
4002 Disable breakpoints instead of giving an error.
4003 source.c (select_source_symtab): Initialize cs_pst.
4004 symmisc.c: Call CLEAR_SOLIB if defined.
4005 symtab.h: Make text{low,high} CORE_ADDR not int.
4006 (psymtab): New field addr.
4008 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
4009 (record_misc_function): Give correct type for N_DATA symbols.
4010 (condense_misc_bunches): do "misc_function_count = j" regardless
4012 Take code which is shared between symbol_file_command and
4013 add_file_command and put it into partial_symbol_file_{open,read}.
4014 Split add_file_command into add_file_command and add_file.
4015 Make psymtab_to_symtab read in the string table if the file
4017 Two new parameters to read_dbx_symtab and start_psymtab.

4020 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4022 * infcmd.c: Change cont_command to continue_command and "cont"
4025 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4027 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
4029 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
4031 * values.c (USE_STRUCT_CONVENTION): Check for structures of
4032 size 1,2,4,8 rather than size < 8.
4034 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
4035 as necessary, not just once.
4037 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
4039 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4041 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
4043 * tm-news.h: Add CALL_DUMMY_*.
4045 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
4047 * config.gdb: In list_host, list_target, use ${i}, not $i.
4049 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4051 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
4053 * sparc-opcode.h: Change all store floating-point state register
4054 instructions to have the right match & lose fields.
4056 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4058 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
4060 config.gdb: If srcdir != ., create readline directory and
4061 copy a makefile into it.
4063 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
4064 consistency with POSIX.
4066 * breakpoint.c (bpstat_stop_status): Disable watchpoint
4067 when we exit its exp_valid_block.
4069 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
4071 * Makefile.dist: Bump version to 3.91.3.
4073 * Clean up handling of breakpoint commands (somewhat).
4074 Prompted by Tiemann bug report "cont 10" doesn't work any more.
4076 inferior.h: Add breakpoint_proceeded to inferior status struct
4077 and globals; save it and restore it.
4078 (clear_breakpoint_commands): Cleanup, remove old #define.
4080 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
4081 (save_inferior_status, restore_inferior_status): handle it also.
4082 (proceed): Remove earlier code that set breakpoint_proceeded.
4083 It is now set only in clear_proceed_status.
4084 (clear_proceed_status): Cleanup, use bpstat_clear rather
4085 than clear_breakpoint_commands. No callers need the stop_bpstat
4086 between clear_proceed_status and proceed.
4088 infcmd.c: Add breakpoint_proceeded definition and comment.
4089 (cont_command, jump_command, signal_command): Move call to
4090 clear_proceed_status right next to call to proceed.
4092 breakpoint.c (bpstat_do_actions): Avoid clobbering our
4093 caller's argument while running down the chain of breakpoints.
4094 Use new variable "breakpoint_proceeded" to determine when
4095 a command that it executes moves the inferior past the
4097 (bpstat_clear): Handle NULL argument.
4098 (bpstat_clear_actions): Avoid useless call to
4099 breakpoint_auto_delete.
4100 (delete_breakpoint): Clean up bpstat's that are pointing to
4101 the deleted breakpoint from the stop_bpstat chain.
4102 (breakpoint_auto_delete): Simplify.
4104 * Clean up handling of EOF, error on stdin, etc. This was
4105 prompted by a network problem that caused gdb to go into an
4106 infinite loop filling up its malloc'd memory.
4108 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
4109 not clear_breakpoints_commands, which is now gone.
4110 (main): If command_loop returns (e.g. from EOF on stdin), do
4111 a quit_command (looping back to command_loop if quit_command
4112 doesn't really quit).
4113 (command_loop): check result from command_line_input and
4114 exit if it returns NULL, rather than passing the NULL to
4116 (gdb_readline): Free malloc'd result space before returning
4119 * utils.c (query): Handle C-d to mean "yes", just as if the
4120 input was not a terminal. Also avoid infinite loop if EOF
4121 occurs in mid-input-line before newline. This allows
4122 query to be used at EOF on stdin with reasonable results.
4124 * infrun.c (proceed): Set breakpoint_proceeded.
4126 * values.c (value_as_long): Avoid infinite recursion for enums.
4127 (_initialize_values): Fix typo in help msg (kingdon).
4129 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
4130 RL_LIB for linking. This allows -lreadline for linking
4131 and nothing for dependencies, once readline is a real library.
4133 * config.gdb: Jim Kingdon: give useful error message if the
4134 host or target type is not recognized.
4136 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
4137 it just defines it. Dumb, but deal with it.
4139 * Jim Kingdon suggests:
4140 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
4142 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
4144 * Makefile.dist (VERSION): Bump version # to 3.91.2.
4146 * Clean up Bothner's changes.
4148 * blockframe.c (clear_pc_function_cache): New function.
4149 * blockframe.c: remake cache_pc_function_* static.
4150 * dbxread.c (symbol_file_command): remove references to
4151 cache_pc_function_* variables.
4152 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
4153 * printcmd.c: Avoid kludging a global variable (addressprint)
4154 to avoid printing the address of a string twice. Instead,
4155 pass the format letter 's' down low enough that it can be seen
4156 to avoid this problem.
4157 (print_formatted): Pass format arg to value_print.
4158 (restore_addressprint): Remove function.
4159 (do_examine): Avoid hacking addressprint, cleanups and such.
4160 (print_frame_args): Add a comment to a Bothner change.
4161 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
4162 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
4163 to wipe out the values cached in blockframe.c.
4164 * symtab.c (find_method): Add comment saying how big you must
4165 allocate to be "big enough". Per being terse again.
4166 * valprint.c (val_print): Handle format letter "s" to print
4167 strings without addresses. Add comment to vtbl printing code
4168 which casts with wild abandon. Rearrange reference-printing
4170 @0xaddr: value (print w/addressprint)
4171 value (print w/~addressprint)
4172 @0xaddr (parameter lists w/addressprint)
4173 or nothing (parameter lists w/o addressprint)
4175 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
4177 * Merge more changes from Per Bothner:
4179 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
4180 annoying) that I tried to improve it. Here are my suggestions.
4182 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
4185 Do automatic de-reference when taking the address of a reference.
4187 Don't deref_ref when printing parameter lists.
4189 More attempts at treating refernences properly.
4191 In val_print, if deref_ref==0, don't print dangling " = ".
4193 Add COERCE_REF macro, which de-references an REF.
4195 * Merge changes from Per Bothner:
4197 * Fixed (Sony news)-specific configuration problems.
4198 * Fixed other problems with using vanilla pcc and libc (enum problems;
4199 assumption that vsprintf exists).
4200 * Some major speed-ups (finc_pc_partial_function now caches a match;
4201 parsing avoids duplicate symbol_lookup calls).
4202 * Changed handling of baseclasses (no longer use baseclasses field
4203 of struct type, use the first n_baseclasses fields instead).
4204 * Various minor changes/fixes, most C++-related.
4207 Cache the most previous match from find_pc_partial_function.
4208 (Save both low and high ends of matching function's pc range.)
4209 This speeds up the loop of infrun.c:wait_for_inferior quite
4210 a bit, and makes step/next commands much zippier.
4212 Added an enum->int cast (otherwise, some compilers barf).
4214 No longer set baseclass offset to 0, since multiple
4215 inheritance now mostly works.
4216 Added a number of casts, to shut up compiler warnings
4217 (after stabs where made enums, not ints).
4218 When discarding a symbol table (in symbol_file_command),
4219 must clear the cache introduced in blockframe.c.
4220 Don't convert $vtbl_ptr_type to vtbl any more.
4221 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
4222 Mask off sign bit emitted by g++ for virtual table offset.
4223 Set voffset to -1 (not 1) for static member functions.
4225 Changed parsing/lexing of names to avoid doing symbol lookup twice
4226 (once when lexing to determine symbol class, once for real).
4227 Now only call symbol_lookup once. Fields of 'this' win especially big.
4229 Subpress printing addr twice in the case of 'x/s addr'.
4231 lookup_basetype_type is no longer used.
4232 Add find_methods as recursive helper function to decode_line_1.
4233 This allows multiple inheritance to work.
4234 Also, once one or more matches has been found, do not look in
4235 base-classes. (Baseclass methods would be overridden, anyway.)
4237 Removed baseclasses array in struct type.
4238 Instead of using baseclasses[i], use fields[i-1].
4239 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
4240 Changed sign convention of voffset (previous was inconsistent).
4242 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4244 Used to assume existence of vsprintf. Re-written to not need it
4245 if HAVE_VPRINTF is undefined.
4247 typecmp was too pessimistic. Made it less so.
4249 Don't print space after address.
4250 If vtable points to a misc symbol (with 0 offset), print it,
4251 since that indicates the actual class of the object.
4252 Changed ype_print_derivation_info to use new inheritance
4253 scheme (without baseclasses vector).
4255 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4256 Also, changes needed because TYPE_BASECLASSES were removed.
4258 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4260 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4263 If there is no path set, and the symbols don't indicate what directory
4264 a file was compiled in, look in the current directory. But either
4265 a path or a known compilation directory will prevent this.
4268 Three independent bug fixes:
4269 * Remove the #if 0 block that breaks some stuff.
4270 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4271 adapt gdb to either SunOS 4.0.* or 4.1.
4272 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4275 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4278 (type_print) Demangle the name being printed.
4279 (type_print_base) Handle botched demangling without coredump (tiemann).
4282 (check_stub_method): Document routine.
4283 (tiemann) fix bug for no-arg functions
4284 Avoid clobbering beyond end of malloc'd storage.
4285 Terminate the argument list properly.
4287 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4289 * Changes merged by John Gilmore:
4292 In breakpoint_1, use new print_address_symbolic instead
4293 of find_pc_partial_function. (This forces use of assembler-level
4294 addresses, and avoids misleading non-mangled source-level names.)
4296 Generalize ansi argument such that -1 means skip arglist totally.
4297 Removed global variable print_ansi_qualifiers (which made
4298 code non-reentrant), in favor of extra explicit arguments
4299 to internal routines.
4301 Add new helper function print_address_symbolic.
4302 Use find_pc_misc_function instead of find_pc_partial_function
4303 (since we want assembler-level symbols here).
4305 Print unknown function as just "f (...)", not "f (...) (...)".
4306 Use new fputs_demangled explicitly.
4308 Fixed a typing violation (problem: value.h cannot be imported
4309 without renaming many variable in this file).
4310 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4311 decode_line_1: Moved forward some never-reached code.
4312 Made decode_line_2 skip function prologues correctly.
4314 fputs_filtered should not demangle by default.
4315 Add new fputs_demangled to demangle on demand..
4317 Change value_struct_elt to use value_primitive_field (using recursive
4318 utility function search_struct_field). This allows foo.bar to work
4319 for multiple inheritance (so far only for data fields).
4320 Change check_field in the same way (recursive helper function
4321 to support multiple inheritance).
4322 (Note: there are more of these problems that I haven't fixed.
4323 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4324 value_of_this: 'this' symbol name is now just "this", note "$this".
4326 Don't print static members.
4327 Avoid printing "members of <type>" if there are none.
4328 Simplified type_print_derivation_info by merging duplicate code.
4329 Remove useless blank lines in type_print_base (ptype command).
4331 Added declaration of new routine value_primitive_field.
4333 Added value_primitive_field which is generalized version of
4334 value_field that can handle multiple inheritance (non-zero offsets etc).
4335 Re-implemented value_field to call value_primitive_field.
4337 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
4339 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4340 delete the whole environment. Karl Berry reported the bug.
4341 * source.c - fix openp to avoid //'s in filenames, which
4342 trigger an Emacs bug causing it to not be able to find files
4343 when running gdb in a window.
4344 * dbxread.c - zap the #if 0 that botches the add-file code.
4345 It seems to work a lot better without all the code commented out.
4347 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
4349 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
4352 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
4354 * Makefile - added a ${CFLAGS} to a couple of entries,
4355 added remote-sa.sparc.c
4356 * added remote.sa-sparc.c, a modification of remote.c
4357 which conducts a dialog directly with the SparcStation prom.
4358 * breakpoint.c, infrun.c, sparcdep.c added
4359 remote_insert_breakpoint(), and remote_remove_breakpoint()
4360 to breakpoint.c instead of directly writing breakpoint instructions.
4361 * sparcdep.c on remote_debugging,there is no need
4362 to remove signle step breakpoint instructions.
4363 * main.c added "-epoch" flag and "int epoch_interface" to main.c
4365 * printcmd.c - epoch interface sends lisp expressions to open up
4366 epoch windows on inspection.
4367 * valprint.c - added arrayprint, and addressprint and made adding
4368 format controls easier
4369 * wait.h added a couple of undef's because we were getting
4370 complaints about WSTOPSIG and WTERMSIG begin redefined.
4373 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
4375 * symtab.c (decode_line_1): Add support for handling method stubs
4376 in the type information.
4378 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
4380 * values.c (baseclass_addr): Run loop from INDEX+1 to
4381 N_BASECLASSES; otherwise, we can still get into a loop.
4382 @@ This should be restructured to use a cleaner search strategy.
4384 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
4386 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
4387 abbreviation "Tt" for tags which have the same name as their
4390 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
4392 * symtab.c (list_symbols): add ability to set breakpoints on all
4393 the functions which match a particular regular expression.
4395 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
4397 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
4398 should print ANSI qualifiers (such as `const' and `volatile').
4399 All callers changed to call with ANSI == 1, except from
4400 `check_method_stub', which uses old-style syntax.
4402 * symseg.h (struct fn_field): Remove unneccessary `args' field.
4403 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
4405 * values.c (check_stub_method): New function.
4407 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
4409 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
4410 * valprint (type_print_base): Ditto.
4412 * symtab.c (gdb_mangle_typename): New function.
4414 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
4416 * breakpoint.c (catch_command): New function. Provides a
4417 mechanism to set breakpoints based on catch clauses.
4418 (disable_catch): Similar, but disables breakpoints on catch
4420 (delete_catch): Similar, but deleted breakpoints on catch clauses.
4422 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
4424 * blockframe.c (blockvector_for_pc): New function.
4425 * blockframe.c (block_for_pc): Changed to call
4426 `blockvector_for_pc' and get the block itself.
4428 * stack.c (catch_info): New function. Prints info about
4429 exceptions which can be caught in the current frame.
4430 * stack.c (print_frame_label_vars): New function. Similar to
4431 `print_frame_local_vars'.
4432 * stack.c (print_block_frame_labels): Prints out labels that are
4433 defined in this frame. These labels are exceptions that can be
4436 * dbxread.c: Updated to handle N_CATCH symtab types.
4438 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
4440 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
4441 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
4442 when printing the type.
4444 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
4446 * valprint.c (val_print): Use `baseclass_addr' to access the
4447 baseclasses pointed to via the derived class object at VALADDR.
4449 * values.c (baseclass_addr): New function. Casts derived pointers
4450 to baseclass pointers taking virtual baseclasses and multiple
4451 inheritance into account.
4453 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4457 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4459 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
4460 exp_valid_block field correctly.
4462 * infrun.c (wait_for_inferior): When checking "don't even think
4463 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
4464 also check step_resume_breakpoint.
4465 Insert breakpoints and continue (not step) if
4466 step_resume_break_address != NULL, even if another_trap.
4467 If trap_expected and we enter sigtramp, then set up a
4469 If trap_expected is set when we hit the step_resume_break,
4471 When calling resume and trap_expected says tell resume to step
4472 (2 places), also check step_resume_break_address.
4474 * infrun.c (wait_for_inferior): Don't set
4475 prev_{pc,sp,func_{start,name}} before calling wait ().
4476 Do set them after exiting loop.
4477 Move their declarations outside functions.
4478 (start_inferior): Initialize them.
4480 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4482 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
4483 Restore old code which distinguishes between trap_expected and
4484 running_in_shell, just make the latter take any non-TRAP signal,
4487 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
4489 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
4490 xconfig/3b1 (CC,PINSN_CC): Define.
4492 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.
4496 * breakpoint.c (bpstat_stop_status),
4497 infrun.c (wait_for_inferior) [SHIFT_INST_REGS]: New code.
