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

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

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

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

1215 (add_target): Call add_cmd and mess with targetlist->doc.
1216 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
1217 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.

1247 command is add-symbols.
1248 * target.c (dummy_target): Permit add_syms_addr_command.
1250 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1252 Permit symbols to be superseded when new symbol files have
1253 been read in, particularly for VxWorks.
1255 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
1256 to the main file, as well as to include files. Also, put global
1257 functions into the global psymtab, to make "i fun" work.
1258 (end_psymtab): Free named symtabs and psymtabs for a file, once a
1259 new psymtab for it has been read.
1260 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
1261 a file, once a new symtab has been read for it.
1262 * mipsread.c: FIXME. We need to do the same for MIPS, but it
1263 looks harder to determine the top-level block before it's been
1264 queued to the psymtab list.
1266 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
1267 If we have wiped out any old symbol tables, clean up at end of
1269 (symbol_file_command): Don't reference symfile_fns if it's zero.
1271 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
1272 defines for the blocks of a blockvector that contain global and
1273 file-static symbols and the first of the smaller scope contours.
1274 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
1275 decode_line_1, make_symbol_completion_list): Use the above.
1276 * coffread.c (end_symtab, patch_opaque_types): Ditto.
1277 * dbxread.c (end_symtab): Ditto.
1278 * expread.y (block): Ditto.
1279 * mipsread.c (throughout): Ditto.
1280 * symmisc.c (free_named_symtabs): Ditto.
1282 * symtab.c (list_symbols): Process the first symbol of the
1283 static psymbols list.
1284 (types_info): Restore this function from its untimely #if 0.
1285 It's not perfect, but it is better than nothing.
1286 (_initialize_symtab): Restore "info types".
1288 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1290 * m68k-stub.c: Remote stub for 680x0's, created from
1291 rem-m68k.shar (which is removed).
1292 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
1293 Remove RCS log stuff now that we use CVS and it blows our diffs.
1295 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1297 * symmisc.c (free_named_symtab): Make it work, in its current
1298 kludgy fashion. Change result to indicate if we blew away bkpts.
1299 * dbxread.c (end_symtab): Accumulate result from
1300 free_named_symtab and print warning if we blew user's state.
1301 * symfile.h: free_named_symtab now returns an int.
1303 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1305 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
1306 is the first symbol read, even if not mainline.
1307 (dbx_psymtab_to_symtab): symfile might be zero, cope.
1308 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1309 (set_section_command): New command ("section xxx yyy" -- should
1310 be renamed to "set section xxx yyy" FIXME) which sets the
1311 base address of a section of the exec file, overriding the
1312 virtual address that BFD reports.
1314 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1316 * exec.c: Add add_syms_addr_command to exec_ops, so you can
1317 load symbols at any address while examining an exec file.
1319 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1321 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1322 for printing the float info is host-dependent, not
1323 target-dependent. FIXME.
1324 * i386-pinsn.c: Move #includes to top, remove useless ones.
1325 * i386-tdep.c: Don't bother including <.../reg.h> since we
1326 don't use it (and it doesn't exist on host systems).
1328 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1329 Convert negative numbers properly.
1330 (ieee_test): Make numbers really random; fix format arg.
1332 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1333 * core.c (core_detach): Unpush core_ops, which might not be on
1334 top. We used to just pop the top, which broke things. Don't
1335 need dont_repeat() any more.
1336 (core_file_command): Psst! Don't repeat it.
1337 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1338 * expprint.c (print_subexp): Avoid switch fallthru on
1339 BINOP_ASSIGN_MODIFY, so we can print += and such.
1340 * frame.h: Fix typo.
1341 * inflow.c (kill_command): After killing inferior, print our
1342 current frame in the core file, if we have one.
1343 (generic_mourn_inferior): When inferior dies, either select
1344 the current frame (in the new target, e.g. core file), or
1345 set both the current and selected frames to NULL.
1347 Changes from Peter Schauer.
1349 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1351 * Make all file names fit in 14 characters (sigh and damn!):
1352 mv hp300hpux-xdep.c hp300ux-xdep.c
1353 mv symmetry-xdep.c symm-xdep.c
1354 mv symmetry-tdep.c symm-tdep.c
1355 mv convex-opcode.h convx-opcode.h
1356 mv tm-vxworks960.h tm-vx960.h
1357 mv tm-vxworks68.h tm-vx68.h
1358 mv Makefile.srcdir Makefile.sdir
1359 mv gdb-int.texinfo gdbint.texinfo
1360 mv remote-sa.m68k.shar rem-m68k.shar
1361 mv remote-multi.shar rem-multi.shar
1362 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1363 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1364 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1367 * command.c (user_info_1, user_info): New command for listing
1368 the user-defined commands.
1370 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1372 * dbxread.c (really_free_pendings): Clear file_symbols
1373 and global_symbols after freeing them; otherwise, running
1374 this function twice (if it appears twice on the cleanup
1375 chain), we try to free things twice.
1377 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1378 based on text_addr (the address of text in core), not on addr (the
1379 offset between text in the .o file and in core). This change
1380 is from Peter Schauer.
1382 * main.c: Define ALL_CLEANUPS as a cast of zero.
1383 (return_to_top_level): Use it.
1384 (main): Do all cleanups after each command run as part
1385 of the gdb startup sequence. Also do all cleanups before
1386 entering the command loop, and every time we exit the command
1387 loop and reenter. Before, the cleanups from the startup sequence
1388 were being left undone until the first error!
1389 (command_loop): Rename do_nothing cleanup to command_loop_marker
1390 so we can see it easily when examining the cleanup chain.
1391 (init_signals): Add another do_nothing for signal handling.
1392 (quit_command): Only try to kill target if it has execution.
1393 Problems in the target stack got us into a state where
1394 inferior_pid was nonzero but none of the targets had execution.
1395 In this state you couldn't exit gdb.
1397 * dbxread.c: Two changes from Peter Schauer.
1398 (echo_command): Fflush output after an echo command.
1399 (show_history): Pass all args to cmd_show_list.
1401 * utils.c (init_malloc): Call mtrace to turn on tracing
1402 if the environment variable MALLOC_TRACE is set to a file name.
1403 * mtrace.c: Add source file which provides a log of every malloc,
1404 free, and realloc to a trace file.
1405 * mtrace.awk: Add source file which analyzes the trace file.
1406 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1407 (VERSION): Roll to 3.94.3.
1409 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1410 (check_duplicates): Don't bother with watchpoints.
1411 (set_raw_breakpoint): Comment about danger of this routine.
1412 (watch_command): Parse and eval all args before calling
1415 * solib.c (find_solib): Avoid error in referencing memory to
1416 see if any more shared libraries have been added. This is
1417 particularly useful if the target has terminated. Bug reported
1420 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1421 in bringing up 3.94.2 on the Sun-3.
1423 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1424 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1425 expression (in scope) before reenabling watchpoint.
1426 * signame.c (init_sigs): Add missing declaration of i, fix
1427 sys_siglist declaration.
1428 * source.c (list_command): Fixed range computation to use
1430 * stack.c (backtrace_command): Do not allow command if target has
1431 no stack, print informative error message.
1432 * target.c (target_command): Do not write into command line
1433 because this fails if the target command is used in a user defined
1434 command. [This change was enhanced by gnu to support any-
1435 unique-prefix matching on target names.]
1436 * valops.c (value_struct_elt): Avoid infinite loop on an
1437 erroneous attempt to print the member of function (try p main.p).
1439 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1441 * expread.y (name_no_typename): Avoid reduce/reduce errors
1442 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1443 Since the GDB parser really doesn't use name_no_typename in a
1444 name-only context, the parser can't tell the diff between
1445 names and numbers here. Avoid allowing a name_no_typename
1446 to be a NAME_OR_*INT to resolve the conflict.
1448 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1450 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1452 * valprint.c (val_print_fields): bitfield printing didn't handle
1453 byte order. Indirect through a few more fns to cope.
1455 * values.c (modify_field): also cope with byte order.
1457 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1459 Cleanup for release 3.94.2:
1461 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1462 include files. Roll version to 3.94.2.
1464 * coffread.c (init_stringtab): Read length into unsigned char
1465 array before swapping; don't assume 32-bit longs.
1467 * target.c (target_info): Don't bother with get_sym_file, just use
1468 the symfile global variable.
1469 * symtab.h, symfile.c (get_sym_file): Delete it.
1471 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1472 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1473 (read_type): Replace one more error() with complain().
1475 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1477 * i960-tdep.c: Fix copyright attribution.
1479 * config.gdb: Quote all backquotes in doublequotes. You can
1480 quote me on that. BSD 4.4 shell found this one.
1482 * infptrace.c (throughout): The third argument to ptrace is an
1485 * infrun.c (wait_for_inferior): When program has terminated, we
1486 have to call target_terminal_ours before we pop that target off
1487 the stack (e.g. before a call to target_kill or
1488 target_mourn_inferior). This fixes problem where a program
1489 terminates, then GDB stops for (tty output) and you have to type
1490 "fg" to the shell to resume it. FIXME: This code for what to
1491 do after termination really should be in normal_stop instead.
1493 * gdbcore.h (read_memory_check): Change declaration; it changed
1496 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1497 4.4 prereleases, this avoids a bug in their sgtty compatability
1499 * remote.c: Use terminal.h rather than hand-rolling the same.
1501 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1502 * utils.c (strsave, strstr): Fix arg types.
1503 * valprint.c (val_print): lint
1505 MIPS symbol table support from Per Bothner:
1507 * symfile.c (symtab_fns): Remove initializer table that needs to
1508 be hacked for each new symbol file format supported.
1509 (add_symtab_fns): New function, chains symbol table
1510 handlers into the global list.
1511 (symfile_init): Search this list.
1512 * symfile.h: Add next pointer, declare add_symtab_fns.
1513 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1514 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1516 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1517 symbol *). Thus, we no longer need the hack to trash
1518 pst->filename. Good, since that hack confused code in symfile.c!
1520 (reorder_symtabs, destroy_all_symtabs): Removed static
1521 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1522 Instead, the latter now uses a temporary array (stack-allocated
1523 from an obstack, and then freed).
1525 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1526 haven't been set in the outermost stBlock of a procedure. This was
1527 a problem with f77 binaries on Ultrix 4.?.
1529 (new_symtab, new_symbol, new_type): Continue changing code to use
1530 obstacks more and otherwise conform to dbxread internal style.
1531 Made the free_code of symtabs be free_linetable (as in dbxread)
1532 instead of free_contents. This implies memory leaks when reading
1533 a new symbol table, until the conversion is finished. Did change
1534 (struct symbol) and (struct type) to be allocated on the
1535 symbol_obstack. Blocks and blockvectors are among the things
1538 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1539 tested much, but it solved one problem (reported by Meissner), and
1540 cleans up some other things. The problem happened when an
1541 included file contains actual code (functions) and not just
1542 definitions. The mips coff is a little inconvenient there, since
1543 it may cause a procedure to be mapped to the wrong psymtab.
1545 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1546 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1547 this will need work for the new core paradigm.
1549 Opcode patches from the net:
1551 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1552 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1553 missing altogether - they are added here. From Bruce Bauman.
1554 * mips-opcode.h: The low mask for C0 instructions was too small.
1555 From Garrett Lau. I modified the fix to check the entire 32-bit
1558 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1561 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1563 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1565 * dbxread.c (read_type): Pointer subtraction (value_sub in
1566 valarith.c) sometimes failed because the types of the
1567 pointers being subtracted were not identical.
1568 These differed because dbxread.c was allocating pointer types
1569 using dbx_alloc_type+smash_to_pointer_type instead of
1570 lookup_pointer_type. I failed to find a justification for the
1571 former, so I changed it to use the latter. Similarly, I
1572 replaced smash_to_function_type by lookup_function_type,
1573 and smash_to_reference_type by lookup_reference_type.
1575 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1576 _initialize_mipsread): corresponding changes.
1578 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1580 * source.c (mod_path): Do tilde_expand on each component of the path,
1581 rather than on the (list of) paths as a whole.
1582 (print_source_lines): Set first_line_listed in addition to
1583 current_source_symtab and current_source_line. If the source was
1584 not findable, after a "dir" command to fix the problem,
1585 a "list" would get the wrong lines.
1587 While I was there... (gnu):
1589 * dbxread.c (read_type): Change error to complaint.
1591 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1593 First attempt at detailed understanding of symbol table memory alloc.
1595 * dbxread.c (dbx_symfile_read): Free our string table if we
1596 aren't the mainline. Free the "info" struct since we're done with
1598 (init_psymbol_list): Free any previously allocated psymbol lists.
1599 (): FIXME: Should realloc-down the psymbol lists when done reading
1600 the main symbol file?
1602 * symmisc.c (free_symtab): Free fullname field too.
1604 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1605 (REGISTER_ADDR): Make result type unsigned int.
1607 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1608 define REGEX must also define REGEX1 (its dependency).
1610 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1612 * tconfig/i960: No longer works, points you at vxworks960 or
1615 * xgdb.c, XGDB-README: Remove file. Users can get the much
1617 * Makefile.dist: Remove all trace of xgdb.
1619 * breakpoint.c (breakpoint_1): Pass demangle arg to
1620 print_address_symbolic.
1621 (clear_breakpoints): Remove unused function.
1622 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1623 (breakpoint_re_set): Use catch_errors to do them all anyway.
1625 * gdb-int.texinfo (Host versus Target): Add section on what is
1626 a "host" feature versus what is a "target" feature.
1628 * infcmd.c (path_command, path_info): Handle the PATH variable
1629 (object search path) as conveniently as the source search path.
1630 * environ.c (set_in_environ): Set some vars in GDB's environment,
1631 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1632 * source.c (mod_path): New function, from guts of
1633 directory_command, modifies a path. Used by path_command.
1634 (directory_command): Call it.
1635 * defs.h (strsave): Declare.
1637 * utils.c (sevenbit_strings): Add new printing option.
1638 (printchar): Use it.
1639 (strsave): Provide this handy helper routine.
1640 (set_width_command): Rename set_screen_width_command.
1641 (_initialize_utils): "set screen-width" => "set width";
1642 "set screen-height" => "set height"; add sevenbit-strings.
1644 * infcmd.c (do_registers_info): Print floating point registers
1645 in raw hex as well as float format, regardless of whether it is
1646 a "virtual" convertible register.
1647 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1648 regs as a double, just in case it's being used that way.
1649 * values.c (unpack_long): Comment on array/function coercion.
1650 (unpack_double): Argument is in target byte order now. For
1651 integer arguments, just call unpack_long and float the result.
1652 * m68k-tdep.c: include defs.h for "const" handling.
1653 * remote-nindy.c: Use ieee-float stuff.
1654 (nindy_fetch_registers): Unpack double regs to host double, then
1656 (nindy_store_registers): Pack extendeds to host double, flip
1657 around by misusing unpack_double, send as target double.
1659 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1660 zero, as when stopped at the first instruction of a process.
1662 * blockframe.c: Fix filename in comment (param.h => tm.h).
1663 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1664 * tm-68k.h: Fix typos.
1666 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1668 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1670 * coredep.c (fetch_core_registers): Pass end-address of register
1671 section to register_addr as expected. Don't call supply_register
1672 if we'd just pass it garbage.
1674 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1676 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1678 * target.c (push_target, target_info): Cast enums to int for < or
1681 * stack.c (print_frame_info): Identify source file & line
1682 even if we can't print it.
1684 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1686 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1688 Clean up IEEE floating point support.
1690 * ieee-float.h: New file.
1691 * ieee-float.c: Write real routines to convert between host
1692 doubles and various target IEEE extendeds.
1693 * m68k-xdep.c: Eliminate assembler code for extended floats.
1694 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1695 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1696 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1697 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1698 double_to_ieee_extended.
1699 * i960-tdep.c: Define ext_format_i960.
1700 * m68k-tdep.c: Define ext_format_68881.
1701 * sparc-tdep.c: Define ext_format_sparc, though unused.
1702 * Makefile.dist (HFILES): Add ieee-float.h.
1703 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1706 Obsolete the "coffstrip" program in favor of using BFD's strip.
1708 * nindy-share/coffstrip.c: Remove file.
1709 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1710 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1711 * tconfig/nindy960: Remove reference to coffstrip.o.
1713 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1715 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1717 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1718 * dbxread.c: Remove static symfile_bfd.
1719 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1721 * inftarg.c (child_detach): Pop the child_ops vector if the
1722 detach is successful.
1723 * remote-nindy.c (nindy_create_inferior): Don't push a new
1724 nindy_ops since nindy uses the same one for execution and memory
1726 * core.c (core_ops): Use child_attach and child_create_inferior
1727 rather than default attach and create_inferior functions.
1729 Handle floating point registers in core files.
1731 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1732 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1733 This version untested since BFD doesn't yet support sun3 core
1735 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1736 conventions. Fix comments and style. This version has not
1737 been compiled yet, since we have no HP inhouse.
1738 * core.c (get_core_registers): Look for two sections, ".reg"
1739 and ".reg2", and pass both to fetch_core_registers sequentially.
1741 Revise directory path yet again.
1743 * source.c (forget_cached_source_info): Not static any more.
1744 (init_source_path): New default source path is "$cdir:$cwd".
1745 (dir_command): Handle variable arguments ($cdir, $cwd).
1746 (source_info): Print "Compilation directory" rather than
1747 "Originally compiled in" to remind people of $cdir.
1748 (openp): If the path contains $cwd, use current directory.
1749 (open_source_file): If compilation directory is known, replace
1750 first $cdir in path with the compilation directory.
1751 (print_source_lines): Even if we can't print the lines, set the
1752 current symtab and line for future commands like "info source" or
1753 "breakpoint". Also, error message now contains the file name,
1754 line number, and file access error message.
1755 (_initialize_source): Fix help text to describe changes.
1756 * main.c (cd_command): Forget cached source info when we chdir.
1757 * utils.c (strstr): Add simple implementation.
1759 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1761 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1762 Byte-swap COFF symbol tables if necessary when reading them in.
1763 Use complain() to replace error message in one spot. Needs
1764 corresponding change in bfd/coff-code.h to make some symbol
1765 swapping routines non-static.
1767 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1769 Merge changes from Eirik Fuller, for UTek.
1771 * defs.h (errno): Add declaration.
1772 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
1773 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1774 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1775 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
1776 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
1777 declarations of errno.
1779 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1781 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1782 <rpc/rpc.h> and <rpc/types.h>.
1784 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1786 * i960-tdep.c (examine_prologue): Add new argument limit,
1787 which stops the scan at the end of the prologue, or at the PC.
1788 This fixes a problem where it walks down into the code for the
1789 user's statements if that code looks like function prologues.
1790 Mark Fox and I have been bouncing this code back and forth, making
1791 small changes to it. Callers changed to match.
1793 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1795 Cleanup for gdb-3.94 release final:
1797 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1798 the .c files from vx-share and nindy-share, from the various
1799 macros, since they are not found via ALLDEPFILES.
1800 (SFILES): Add tm-i960.h.
1801 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1802 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1804 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1805 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
1807 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
1809 * am29k-tdep.c: Add contribution line.
1810 (examine_prologue): Cache information about function prologues in
1811 the misc-function-vector to avoid lots of references over the
1812 serial line while examining instructions.
1814 * core.c (core_close): New function made from cleanup_core.
1816 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1817 remote-vx.c, remote.c, target.c, target.h,
1818 Update target_ops vector to add attach, close, and load entries.
1819 Use add_syms_addr_command, not add_file_addr_command, for
1820 add_file. Break out close routine from existing code.
1822 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1823 they are in an obstack.
1824 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1826 (define_symbol): Add symbol type parameter; change callers;
1827 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1828 it to influence the symbol class on the i960.
1829 (define_symbol): Swap LOC_CONST's into target byte order.
1831 * exec.c (exec_close): New function.
1832 (exec_file_command): Call it.
1834 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1835 Fix byte order of frame pointer.
1836 (read_var_value): Result of 0 if var's value can't be found,
1837 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1838 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1839 (locate_var_value): Use read_var_value and use its lazy address
1840 as the location of the var's value. Lint.
1842 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1845 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1846 obsolete Intel versions in favor of vxgdb versions.
1847 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1848 code dealing with byte order of values, which Intel did in host byte
1849 order rather than gdb-4's target byte order.
1850 (i960_frame_chain_valid): Move to nindy-tdep.c.
1851 (examine_prologue, skip_prologue, frame_find_saved_regs,
1852 frame_args_address, leafproc_return, saved_pc_after_call,
1853 pop_frame): Add vxgdb versions from Mark Fox.
1854 (examine_prologue, frame_struct_result_address): Add code
1855 to deal with the saved value of G13 (struct return address
1857 (frame_args_address): Modify Mark's version to prefer the
1858 saved value over the current value in the topmost frame.
1859 Cache result in the frame info to avoid performance hair in
1861 (print_fault): Add gdb960 code for printing faults.
1862 (_initialize_i960): Actually call check_host.
1864 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1865 add stub routines. FIXME, these currently just return zero!
1867 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1868 (attach_command): Call target_attach, not target_open, now.
1870 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1871 (child_attach): Rename from child_open.
1872 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1873 don't confuse it with a zero step_resume_break_address.
1875 * inftarg.c (child_detach): Eliminate inferior_pid test.
1876 (child_files_info): Clean up message a bit.
1877 (child_ops): Use child_attach, not child_open, to attach.
1879 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1880 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1881 findvar.c to here, since it depends on the contents of the
1882 shadow_contents of breakpoints, but keep if #if 0 since it is
1885 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1888 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1889 (ptype_command, display_command): Eliminate have_inferior_p and
1890 have_core_file_p in favor of target_has_stack or
1891 target_has_execution.
1892 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1893 code for actually finding the values of arguments, though we still
1894 keep track of the maximum stack offset for use in printing unnamed
1895 arguments. Handle missing FRAME_ARGS_ADDRESS.
1897 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1898 (struct nindy_regs): Define registers passed to/from nindy.
1899 (nindy_fetch_registers, nindy_store-registers): Translate between
1900 nindy and GDB formats for the registers.
1901 (dcache_init): Statically allocate the cache, since it was being
1902 allocated by a malloc that was never freed anyway.
1903 (nindy_create_inferior): Error, not core dump, if no exec file.
1904 (nindy_before_main_loop): Use target_load, not target_add_file.
1906 * remote-vx.c (net_load): Specify large timeout for load
1907 requests. Allow user to break out with INTERRUPT.
1908 (net_break): Remove useless code, clean up. Change callers.
1909 (parse-args, skip_white_space, find_white_space): Clean up arg
1910 parsing to cope with quoted strings.
1911 (net_wait, net_quit): Never call error, just return status.
1912 (vx_read_register, vx_write_register): Cleanup status checking.
1913 #ifdef the code based on which CPU we are using (960 or 68k),
1914 FIXME, this should be completely general but it isn't yet.
1915 (vx_xfer_memory, vx_resume): Cleanup status checking.
1916 (vx_run_files_info): Improve message.
1917 (vx_load_command): Renamed from vx_add_file_command. Allow load
1919 (net_ptrace): Remove unused routine.
1920 (vx_wait): Adopt code from vxgdb960 to cope with broken
1921 connections to target machine and prompt to disconnect. Remove
1922 debug printouts. Map some EVENT_'s to SIGnals.
1923 (add_symbol_stub, vx_open): Print names of object files we found,
1924 and "ok" if we read their symbols OK. Clarify output in general.
1925 (vx_attach, vx_detach, vx_kill): Add these commands.
1926 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1927 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1928 "info files" output, and create_inferior, since we already have
1931 * stack.c (frame_info): Replace Frame_unknown with 0.
1932 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1933 (return_command): Pop until the PC matches as well as the FP,
1934 so it works even if the FP is shared with another function,
1935 as in "frameless" or "leaf" procedures.
1937 * symfile.c (load_command): renamed from add_file_target_command.
1938 (add_syms_addr_command): renamed from add_file_addr_command.
1939 (add_syms_command): Stub to call target_add_syms.
1940 (_initialize_symfile): Change command names and descriptions,
1941 add-file => add-syms, and load from alias to its own command.
1943 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1944 maybe_kill_then_create_inferior): Default for attempts to start
1945 a process, if one is already running, is to ask about killing
1946 it and retry if yes.
1947 (upstack_create_inferior): #if-0 it, strata obsolete it.
1948 (push_target, unpush_target, pop_target): to_close() a target
1949 before unstacking it.
1950 (target_info): Renamed from target_files_info.
1951 (_initialize_targets): Rename "i files" as "i target", accessible
1954 * target.h: Improve comments about the target_ vectored routines.
1956 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
1957 Convert commenting style to standard GNU style.
1958 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
1959 (SKIP_PROLOGUE): No longer a no-op.
1960 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1961 (*_REGNUM): Sort register numbers.
1962 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1963 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1964 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1965 are now 10 byte extendeds, not 8 byte doubles.
1966 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1967 for nindy versus vxworks targets. FIXME, this should possibly go
1968 in the target vector.
1969 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1970 frame_saved_regs and arg pointer with each frame.
1971 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1972 (FRAME_ARGS_ADDRESS): Use cached result.
1973 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1974 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1975 (PRINT_RAMDON_SIGNAL): Call print_fault.
1976 (POP_FRAME): Now works.
1978 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1979 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1980 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1981 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1984 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1985 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1987 * valarith.c (value_subscripted_rvalue): Avoid handling
1988 floats and doubles specially; it gave alignment errors. Lint.
1990 * valops.c (value_of_variable, value_of_this): Error if unknown
1993 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1994 to avoid alignment problems.
1995 (value_print): Handle unknown value address.
1996 (cplus_val_print): Two args are ignored; remove them. Change caller.
1997 (val_print): Use unpack_long rather than pointer-deref.
2000 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
2001 to avoid alignment problems.
2002 (value_being_returned): Error if return value unknown.
2003 (set_return_value): Add bogosity warning, FIXME. *
2005 * TODO: A woman's work is never done.
2007 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
2008 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
2009 Add ieee-float.o to OBS.
2010 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
2011 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
2012 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
2014 Changes to generalize the VxWorks RPC protocol slightly, to handle
2015 i960 as well as 68000.
2017 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
2018 * vx-share/reg.h: Produce i960 regs #ifdef I80960
2019 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
2020 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
2021 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
2022 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
2023 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
2024 so they will move in target byte order rather than network
2025 byte order (happens to be the same).
2027 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2029 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
2031 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2034 Add contribution lines to various files, showing where they
2037 * breakpoint.c (break_insn, check_break_insn_size,
2038 read_memory_nobpt): Remove to mem-break.c.
2040 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
2043 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
2044 entry has bad register number. This change is not
2045 tested in this release, FIXME.
2047 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
2050 * value.h: Force value's contents field to be aligned to hold
2051 at least a double or a long long (if supported). This avoids
2052 doing bcopy's in and out of the contents field.
2054 (step_1): Avoid coredump under obscure circumstances when we
2057 * symtab.h (misc_info): Add field to misc function vector for
2058 any kind of cached information the target code desires. AMD
2059 29000 uses this to avoid repeating examine_function_prologue's.
2061 * coffread.c: Lint. Remove static symfile, read_section_header.
2062 core.c (have_core_file_p): Lint: remove.
2063 expprint.c (print_subexp): Lint.
2064 infptrace.c, valops.c, valprint.c: lint.
2066 Roll in changes from vxgdb-5.0.1:
2068 * symtab.h: Comment byte order of each address class. Add
2069 LOC_LOCAL_ARG for frame-relative args (960).
2070 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
2071 symtab.c, symmisc.c: ditto.
2073 * infrun.c (init_wait_for_inferior): Clear stop_signal.
2075 * remote.c (remote_resume): Error if resume with a signal.
2077 * symfile.c (prim_record_misc_function): Clear misc_info.
2078 (fill_in_vptr_fieldno): Check stub type of arg.
2080 * valops.c (value_cast): Avoid looking up names of types whose
2081 name we don't know, to prevent coredump. Sun CC produces typedef
2082 rtx and the name of *rtx is zero...
2084 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2086 Roll in changes from final AMD 29000 port (Tiemann).
2088 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
2089 for ../include/a.out.encap.h. This might not work now that BFD
2090 is separately compiled. Instead, BFD support for encap will have
2091 to translate machine type 29k into the right COFF_MAGIC.
2093 * infcmd.c: Remove references to inferior_pid that aren't used
2094 in actual ptrace calls; use target_has_execution, etc.
2095 (have_inferior_p): Remove function.
2096 (program_info): Print target info rather than "process number";
2097 avoid gratuitous messages unless from_tty.
2098 (run_stack_dummy, finish_command): Set proceed_to_finish.
2099 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
2100 main.c: Lint. Lose have_inferior_p().
2101 inferior.h (have_inferior_p): Remove, lint.
2102 (proceed_to_finish): Add flag to ask that all regs be saved
2103 by normal_stop, for the few commands that need it, speeding up
2104 serial I/O. Add comments to stop_registers.
2106 * remote-eb.c: Remove newline from breakpoint message we grep
2107 for. Never time out when running the user program.
2111 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2113 Roll in changes from vxgdb-5.0.1:
2115 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
2116 symbol in its raw form, we are processing an unlinked ".o" file.
2117 See if the target environment has assigned it an address, using
2118 target_lookup_symbol (VxWorks does), and enter it into the symtab
2121 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
2122 68k versions for a simpler version that assumes zero FP at bottom.
2123 Fixes bug of truncated stack reports.
2125 * target.h (target_lookup_symbol): Define this routine's args
2126 and result, finally.
2128 * target.c (nosymbol): Default routine for target_lookup_symbol.
2129 (target_default): Default lookup_symbol and call_function too.
2130 (files_info): Only print has_all_memory warning if a non-dummy
2133 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
2134 vx_convert_from_virtual): If target does not have floating point,
2135 zero register "values", and avoid doing cross-net conversions.
2136 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
2137 (vx_open): Rearrange code that attaches to target and reads
2138 symbols for all loaded modules, to work if some of the modules
2139 are not accessible. Add symbol_stub() and add_symbol_stub()
2140 as callbacks from catch_errors(). Allow connect attempt to be
2141 interrupted painlessly with ^C (FIXME, there are still some bugs
2142 if the interrupt happens during symbol reading.). Print
2143 final message with puts_filtered, since symbol messages are
2148 * main.c (catch_errors): Only print errstring if non-null.
2149 (command_loop): Avoid an ioctl per command to test ISATTY.
2151 * remote-vx.c (net_load): make static; avoid sophomoric msg.
2152 (vx_xfer_memory): Return correct result!
2153 (vx_files_info): Indicate whether target has float or not.
2154 (vx_lookup_symbol): Complain, not error, if target gone.
2155 (vx_open): Print "Connected" msg before disabling immediate-quit.
2156 [FIXME: lookup_symbol and vx_open changes need testing.]
2158 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
2159 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
2160 contributor lines and update copyrights to 1991.
2162 Changes from an attempted H-PUX host port:
2164 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
2165 defines PT_ATTACH and PT_DETACH but not PT_KILL.
2166 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
2167 * remote-vx.c: include <sys/time.h> for HPUX.
2168 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
2169 "core_file_command" routine to BFD regime. May not work yet.
2171 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
2173 * xgdb.c: Replace X10 version with some VJ version.
2174 (FIXME: Its copyright assignment is not on record.)
2175 * xgdb.c: Update include files to X11R4 (Xaw crud).
2176 (xgdb_display_source, create_text_widget): fix call to
2177 get_filename_and_charpos. Rewack source window stuff for X11R4
2178 (gleaned from include files, and "nm's" of binary libraries, since
2179 I had no doc available).
2180 (append_selection, append_selection_word): Disable with FIXME
2181 since R4 changed interface here.
2182 (create_buttons): Add back the old set of buttons.
2183 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
2185 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
2186 Roll VERSION to 3.94 (not yet final though).
2188 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2190 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
2191 obstack_int_grow, obstack_int_grow_fast): Eliminate
2192 cast on left of assignment, which gives MIPS cc fits and is
2195 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
2196 F_ALIAS. Use printf, not fprintf, when not passing a file
2198 (compare_opcodes): Check that identical instructions have
2199 identical opcodes, complain otherwise.
2201 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
2202 was reported by Roland McGrath.
2203 (unimp): Only match if exactly zero instruction. (Roland)
2204 (branches and traps): Generate all variations of these
2205 instructions with macros, based on a single call that defines
2206 each condition name and its binary representation.
2207 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
2209 * valprint.c (val_print_fields): Take, and use, format parameter.
2210 This means that "p/x struct" again prints the elements in the
2211 desired format. Changed callers.
2213 * stack.c (frame_info): Use filtered output, and indicate wrap
2214 points. Remove kludgy formatting designed to avoid line wrap.
2216 * utils.c (wrap_here): If the line is already full (because
2217 we had printed a long indent or long wrapped string), do an
2218 immediate newline-and-indent.
2220 * m68k-pinsn.c (print_insn_arg): Bugfix from
2221 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
2222 instruction is incorrectly disassembled as bkpt #8.
2224 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
2225 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
2226 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
2227 and then will dump core (sometimes). I traced it back to an
2228 uninitialized symfile_name in psymtab_to_symtab.
2229 (const_vol_complaint): Add quotes to message.
2230 (define_symbol): Only believe line number if gcc_compiled.
2231 Avoid allocating symbol if we will not return it.
2233 Add target strata support so that newly established targets go
2234 into their right place in the target stack (e.g. a new exec file
2235 doesn't wipe out the ability to access the running process).
2237 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2238 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2239 and initialize it properly in all the targets.
2241 * target.h: Document strata. Change return type of push_target.
2243 * target.c (nomemory): new function for dummy memory access.
2244 (tcomplain): Rename complain, now also used in symfile.c.
2245 (push_target): Push targets within strata. New return value shows
2246 whether new target is on top of stack or not. Always keep dummy
2248 (target_files_info): Ignore dummy target.
2250 * core.c (core_open): Warn user, and skip accessing file, if the
2251 core target is not the topmost target in the stack.
2252 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2255 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2256 target_ops, it doesn't belong there since we have no regs there.
2257 Change name of target from machine => memory to clarify.
2259 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2261 * Freeze version 3.93 for release.
2263 * Makefile.dist: Handle vx-share and nindy-share subdirs
2264 properly when building gdb.tar.Z.
2266 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2267 printed in various places, so I could change just one copy.
2269 * dbxread.c, coffread.c: Change references to bfd->iostream
2270 to cast to FILE *, now that BFD avoids needing types defined
2271 in other header files.
2273 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2275 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2276 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2277 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2278 (actually gcc -Wall).
2280 * dbxread.c: Remove first_global_sym, last_global_sym, since
2281 they are never referenced.
2283 * defs.h (baud_rate): Declare.
2284 main.c: Define it, and add the -b option to set it.
2286 * gdb-int.texinfo: Add text on how to define a new host or target
2287 architecture, prompted by Per Bothner's questions about MIPS
2290 * gdb.texinfo: Document "complaints". Change doc of -q since
2291 gdb no longer prints the copyright and blurb if you specify a file
2292 name to be debugged (just like Emacs). Add doc for Nindy-specific
2293 command line flags for specifying target serial port and such.
2294 Update copyright to 1991.
2296 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2297 has taken over for us the job of ripping up executable files. The
2298 crud caused Per Bothner's port to not compile.
2300 * infrun.c (normal_stop): Avoid printing "Program exited
2301 normally" if we are in batch mode. This allows a GDB which
2302 executes a program on a target system, to behave like a Unix
2303 command (input from stdin, output to stdout, no extraneous
2306 * main.c (main): Allow additional machine-dependent command line
2307 options to be specified with the ADDITIONAL_OPTIONS,
2308 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2309 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2310 processing to occur just before the main loop with
2311 BEFORE_MAIN_LOOP_HOOK.
2312 (main): If a "core file" argument is specified, and it is not a
2313 core file, try it as a process ID to attach.
2314 (symbol_completion_function): Attempt to cope with
2315 "show screen-" TAB, not very successfully. This needs more work,
2317 (batch_file): New function, returns whether we are reading
2318 commands from an interactive tty on stdin, or from somewhere else.
2319 Called by normal_stop since it doesn't get from_tty passed down
2320 to it like many commands do.
2322 * remote-nindy.c: Handle command line options for nindy
2324 (nindy_before_main_loop): Prompt user for tty name if they
2325 don't specify it before getting to the interactive command loop.
2327 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2328 and -r command line options. Also add hook before main loop
2329 to make it easy to specify a tty.
2331 * TODO: More things to do, one done.
2333 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2335 * dbxread.c: Make complaint() calls pass pointer, not struct.
2336 Add complaints about badly formatted C++ type information
2337 (const/volatile indicator, and parse errors resulting in
2338 error_type). Fix C++ virtual member fn comment.
2339 (read_struct_type): Avoid bumping pointer if we got a parse
2340 error; this prevents our walking beyond the end of a string.
2341 Terminate loop on null char as well as semicolon.
2342 (process_one_symbol): Fix the LBRAC fix so that it uses the
2343 last previous SLINE, FUN, or SO record's PC address. C++ debug
2344 symbols did not have SLINE records in a useful order compared
2345 to the LBRAC records.
2346 (define_symbol): Handle "catch" records.
2348 * symtab.c (check_stub_type): Added new complain
2349 `stub_noname_complain' and added a consistency check to
2350 keep the debugger from crashing when finishing from an
2351 exception frame. A real fix will be needed later.
2353 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2355 * infcmd.c (attach_command): Make global.
2357 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2358 but make them easy to comment out. Perhaps later they should
2359 be enabled by what CPU you configure for? FIXME.
2360 (VERSION): Roll to 3.93.
2361 (pinsn.o): Remove rule for obsolete file.
2362 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2364 Run down a problem that manifested by printing the wrong function
2365 name in stack traces of read_ofile_symtab. Turned out that the
2366 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2367 the LBRAC symbol with an address in the *data* segment, which
2368 blew our binary search through the blocks.
2370 * dbxread.c: Use the complain() facility consistently to bitch
2371 about problems in the symbol file we are reading.
2372 (finish_block): Add code to check the nesting of the blocks;
2373 complain and Procrust them to fit if wrong.
2374 (make_blockvector): Check the order of the blocks, complain
2375 [but don't cope] if wrong.
2376 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2377 symbols to be sure their PC value is greater than the last SLINE
2378 (line number) symbol we've seen, complaining and adopting the
2379 SLINE PC value if wrong.
2381 * symfile.h (struct complaint, complaint_root, complain,
2382 clear_complaints): Add.
2383 * symfile.c (complain, complaint_root, clear_complaints): Add
2384 facility to deal with non-fatal complaints and to regularize their
2386 (symbol_file_add): Clear complaint counters to allow new complaints.
2387 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2389 * dbxread.c (dbx_symfile_read): Remember the address and size
2390 of the string table for the main symbol file, so we won't read it
2392 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2393 to avoid reading the string table yet again. Lint.
2394 (throughout): Improve filtered output, including word wrap.
2395 (read_range_type): Improve Bothner's fix to handle other types too.
2397 * utils.c: Improve line wrap implementation. Handle unlimited
2398 width by making chars_per_line unsigned.
2399 (puts_filtered): New, easy, function.
2401 * defs.h (puts_filtered): add.
2403 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2404 call the identical sort_symtab_syms() in symfile.c instead.
2406 * expread.y: Suggest the `file' command rather than `symbol-file'.
2408 * command.h (enum var_types): Add zinteger for seroable
2410 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2411 nested if's into a switch.
2413 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2414 we did not stop because of a breakpoint (it must have been for
2415 some other reason, like a "stepi"), so don't print anything.
2417 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2418 doesn't include <sys/types.h>, old SunOS's require it for
2421 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2423 A test port of gdb-3.92.6 to the Sony NEWS.
2426 Don't normally link in remote- or vx stuff.
2427 Some of it doesn't compile, and it wastes space for 99% of the users.
2428 Remove reference to no-longer-used HAVE_VPRINTF.
2429 Fixed BFD_DEP typo to BFD_DIR.
2431 Fix cast in arg to bfd_h_getlong.
2432 Make char *prefix be const.
2433 Fix how certain range types are mapped into builtin unsigned int types.
2435 Remove 2 #includes. They cause errors (on Sony, at least),
2436 and aren't needed (they wern't in earlier versions).
2438 print_address_symbolic should never demangle labels
2439 (since it prints *assembler-level* labels).
2441 [This was superseded by the change to printcmd below.]
2444 Add some "volatile" return types to avoid warnings.
2445 If MISSING_VPRINTF add vprintf function and not just macro
2446 (since vprintf is used in printcmd.c).
2448 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2449 (The latter isn't grokked by some PCC-based compilers.)
2451 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2453 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2454 * nindy-share/coffstrip.c
2455 Added some forward declarations (otherwise, gcc complains
2456 about implicit extern redefined as static).
2458 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2460 Changes inspired by Per Bothner:
2461 * printcmd.c (print_address_symbolic): Take additional parameter
2462 specifying whether to demangle.
2463 (print_address): Pass in asm_demangle to control demangling.
2464 (print_address_demangle): New fn, takes explicit arg to control
2466 * utils.c: Add new vars demangle and asm_demangle, and let them
2468 (fputs_demangled): If !demangle, just print the argument.
2469 (fprint_symbol): If !demangle, just print raw symbol.
2470 * valprint.c (val_print): Call print_address_demangle rather than
2471 print_address, to cause demangling to depend on the global
2472 rather than assembler-level demangling setting.
2473 * WHATS.NEW, gdb.texinfo: Document.
2475 * main.c (show_command): Show all settings if no arg.
2476 (initialize_main): Make "info set" the same as naked "show".
2477 * command.c (cmd_show_list): Handle prefix commands in the
2478 list, and print the name of the setting as well as its English
2479 description and value.
2481 Allow gdb functions to specify where a line should wrap if it
2482 exceeds the size of a terminal line. Use it to make the output
2484 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2485 of the right size when screen width changes.
2486 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2487 (wrap_here): New fn, indicates a point in the output where we
2488 should wrap the line rather than just letting it overflow at a
2490 (fputs_filtered): Implement wrapping.
2491 (n_spaces): New fn, returns a pointer to N spaces.
2492 (print_spaces_filtered): Use n_spaces.
2493 * defs.h (n_spaces): Declare.
2494 * stack.c (print_frame_info): Wrap with 4-space indent after
2495 fn name and before filename and line number.
2496 * printcmd.c (print_frame_args): Wrap with 4-space indent
2497 before each argument name is printed.
2498 * valprint.c (value_print): Wrap with no indentation before
2500 (val_print_fields): Wrap with indentation relative to nesting
2501 level before each field name.
2502 (val_print): Wrap with nesting indentation before array elements.
2503 * command.c (do_setshow_command): Avoid extra newlines,
2504 wrap with 4-space indent around values printed, end with period.
2505 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2507 * breakpoint.c (breakpoint_1): Implement addressprint for
2508 "info breakpoints" display. Change file name and line number
2509 format to " at file:nnn" rather than " (file line nnn)".
2510 * gdb.texinfo: Document.
2513 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2515 Frozen for gdb-3.92.6 release.
2517 README, WHATS.NEW: Update for 3.92.6 release.
2519 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2520 coffread.o from configs since it is now built by default.
2521 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2522 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2523 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2524 from configs since it is now built by default.
2526 Makefile.dist: Update for release 3.92.6. Handle files that
2527 have been moved to ../include, ../getopt, or ../bfd. Add
2528 saber.suppress and tests directory. Add config.status to
2529 the release (it will say "none").
2531 coredep.c: Minor formatting fixes.
2533 These changes were made in early December but only checked in now:
2534 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2535 nindy-share/nindy.c: lint
2536 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2537 register values coming back from the target; we store values
2538 in target byte order everywhere.
2540 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2542 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2544 * valprint.c (cplus_val_print, val_print_fields): New functions,
2545 which print C++ objects. They conspire to avoid printing a
2546 virtual base class more than once, following all the twists and
2547 turns of C++ virtual base rules.
2548 (val_print): Call the above rather than do it by hand.
2550 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2551 symbol file, not for added files like shared libs. This really
2552 needs to be generalized to a timestamp per file.
2554 * core.c (cleanup_core): Avoid coredump if no core file.
2556 * config.gdb: Accept -host or -target in place of +host or
2559 * coffread.c (find_linenos): Avoid desupported BFD interface
2560 to line numbers. We still read them manually rather than using
2561 BFD's "generic" features.
2563 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2565 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2567 * Makefile.dist: Eliminate use of $< in explicit targets.
2569 * readline/Makefile: Use $< rather than $*.c, which does not
2570 include the VPATH in GNU Make.
2572 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2573 copies of tconfig/i960, added for global configuration
2574 compatability. All i960 versions can read both coff and b.out.
2576 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2577 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2580 * TODO: Think of more things to do.
2582 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2584 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2585 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2586 64-bit float conversion.
2588 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2589 equivalent to sun?os4 so global config works.
2591 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2593 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2595 * main.c: Only declare linesize once; declare pagesize not at
2596 all, since it is never used.
2597 (main): Clear newly allocated line before it is used.
2599 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2601 Further stabilization for the Intel 960.
2603 * Makefile.dist: Parameterize the location of the "include"
2604 and "bfd" directories, as well as "getopt". Add symfile.c.
2605 Link in both dbxread and coffread. Fix up "make depend" to
2606 rewack the locations of include, bfd, and getopt in its output.
2608 * README: Document moving include files, improve some of
2611 * coffread.c: Move common code out to symfile.c. Change
2612 symbol_file_command style interface to use new *_symfile_init
2613 and *_symfile_read interface under BFD. Use BFD internal
2614 info to locate line table, symbols, etc.
2616 * core.c (core_fetch_registers): Rename to get_core_registers
2617 to avoid confusion with fetch_core_registers.
2618 (register_addr): Move to coredep.c, which is already machine
2619 dependent. This leaves core.c pretty clean of dependencies.
2621 * coredep.c (register_addr): Accept this routine from core.c.
2623 * dbxread.c: Move common code (with coffread.c, etc) into new
2624 symfile.c. Each psymtab now contains a pointer to the
2625 format-dependent function that knows how to read it in. Make
2627 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2628 (process_one_symbol): Add code to complain about a "compiler bug
2629 we muzzle here", if we actually see it.
2631 * eval.c (evaluate_subexp): Insert missing "break" statements
2632 in code that determines whether a variable is an lvalue in
2633 memory, register, or whatever. I detected this via a compiler
2634 bug in which it *almost* mashed out the whole switch statement.
2636 * gdb-int.texinfo: Add minor sections on configuring gdb for
2637 release, and about the README file.
2639 * infcmd.c (registers_info): Fix formatting somewhat. Still
2640 not as pretty as before, but it handles byte swapping.
2642 * remote-nindy.c: If data cache routines are interrupted while
2643 waiting for the remote end, be sure that any uninitialized cache
2644 blocks are on the free list, not on the valid list!
2646 * symfile.h: Flesh out this header file with all the various
2647 routines and variables that have been merged in from dbxread.c
2648 coffread.c, and symtab.c to symfile.c.
2650 * symfile.c: New file, containing code common to dbxread.c,
2651 coffread.c, and some code from symtab.c. All generic code for
2652 reading symbol files should be in here now.
2653 (unrecord_misc_function): Remove unused function.
2655 * symtab.h: Remove file-reading things to symfile.h.
2657 * symtab.c: Remove file-reading things to symfile.c.
2659 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2660 to decode i960 fault types.
2662 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2663 target.c: Change type of the "resume" function from int to void,
2664 since its result was never used.
2666 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2668 * main.c: Replace "stupid" with "caution"; you now "set caution
2671 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2673 * infcmd.c (do_registers_info): Call val_print to deal with the
2674 byte order of the registers being printed. FIXME, this makes
2675 the formatting of the output uglier.
2677 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2678 defined, call it for signals the debugger doesn't itself use.
2679 The i960 uses this for more detailed fault information.
2681 * remote.c (remote_open): If arg is null, print help rather than
2684 * sparc-xdep.c (register_valid): Avoid declaring size, since
2685 various modules will think of various sizes depending on the
2686 architecture of their tm-file. FIXME, we need protection against
2687 actually entering one of those modules, which would clobber
2688 storage if not for the target architecture compiled into gdb.
2690 * stack.c (up_command, down_command): Always print the frame
2692 (up_silently_command, down_silently_command): New commands
2695 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2697 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2698 more parameters than it used to.
2700 * findvar.c (registers): Increase slop to 256 bytes, which should
2701 protect us against even most RISC machines with large register
2703 (locate_var_value): Move declaration inside related ifdef.
2705 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2706 throughout, to avoid throwing away buffered input from the board.
2707 (nindy_wait): Supply_register takes addr_of_value, not value.
2708 (i960_print_fault): Renamed from i80960_fault.
2709 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2710 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2712 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2713 we can set the PC in the call to proceed(). Unpush nindy_ops
2714 before pushing it on top, to avoid message to user. Eliminate
2715 commentary from Unix machines that just misleads here.
2716 (reset_command): Fix error message to suggest target command.
2718 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2720 Release 3.92.5 as frozen.
2722 Stabilize the merged release...with help from lint, Saber C,
2725 Everywhere: Add include files needed to declare return types
2726 of functions called.
2728 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2730 * breakpoint.h: Add undeclared breakpoint functions, and some
2731 functions for display handling since I couldn't think of a better
2734 * breakpoint.c (insert_breakpoints): Make code for disabling
2735 shared library bkpts more likely to work. It's used when we
2736 rerun a program and stop before the shared library has been
2738 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2739 cast from pointer, so it squeezes through catch_errors.
2740 (bpstat_stop_status): Fix logic broken some time ago. We now
2741 always create a bpstat if the stop address matches a breakpoint,
2742 even if we don't stop there -- just like the old code used to do
2743 before I got my fingers into it (sigh).
2744 (breakpoint_1): Print "ignore count" after "stop only if"
2745 condition, since that's how it actually works.
2746 (mention): Handle watchpoints as well as breakpoints.
2747 (watch_command): use set_raw_breakpoint and mention to do most
2748 of the work (and initialize all the fields!). Only pass one
2749 arg to parse_c_expression, since that's all it takes.
2751 * command.c (not_just_help_class_command): Rename arg to args
2752 since we ignore "unused argument" warnings on vars named "args".
2753 inflow.c (child_terminal_info): ditto.
2754 infptrace.c (kill_inferior): ditto
2755 main.c (catch_errors, version_info, quit_command, pwd_command,
2756 source_command, dump_me_command, editing_info,
2757 set_history_size_command, set_history, show_history,
2759 stack.c (locals_info): ditto
2760 target.c (target_files_info): ditto
2761 valprint.c (set_input_radix, set_output_radix): ditto
2763 * core.c: Remove old variables for handling core and exec file
2764 sections (data_start, data_end, stack_start, stack_end,
2765 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2766 text_end, exec_data_start, exec_data_end, text_offset,
2767 exec_data_offset, data_offset, stack_offset). They're
2768 superseded the more general build_section_table and
2770 (get_exec_file): Mention the `file' command.
2771 (read_memory_check): Rename to memory_error, and only call it
2772 in the case of an actual error.
2773 (read_memory, write_memory): call memory_error.
2774 (core_fetch_registers): Register section name is ".reg".
2776 coredep.c: Remove a bunch of crud now that all this file does
2777 is pull the registers out of a core file.
2778 (fetch_core_registers): Rewrite to actually work, I hope.
2780 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2781 Replace index() with strchr(). Remove all the pre-BFD macro
2782 definitions for accessing the symbol file.
2783 (struct dbx_symfile_info): Encapsulate the information that
2784 dbx_symfile_init needs to pass to dbx_symfile_read in this
2787 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2788 dbx_symfile_discard): Rearrange symbol file reading to divide
2789 the format-specific part from the format-independent part,
2790 leaving the format-independent part such as file name expansion
2791 and opening in symtab.c. This replaces
2792 partial_symbol_file_open and partial_symbol_file_read.
2793 Symbol_file_read, add_file, add_file_target_command,
2794 add_file_addr_command move to symtab.c. Pass an explicit
2795 "mainline" flag for when reading the main symbol table, rather
2796 than relying on the offset address to be zero or nonzero.
2798 (dbx_symfile_read): Don't allow void *'s to be printed as
2800 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2801 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2802 macro" debug version really work.
2803 (read_dbx_symtab): Remove unref'd parameter inclink.
2804 Avoid swapping N_SLINE symbols, for speed.
2805 Merge N_TEXT!N_EXT case with the other external symbol
2806 definitions' case. Add comments.
2807 (start_psymtab): Allocate the symfile name in the psymtab on
2808 the psymbol_obstack, rather than using the caller's storage.
2809 (end_psymtab): Only allocate a dependencies list if there are
2811 (psymtab_to_symtab_2): Use BFD when reopening file to read
2812 its symbols for real.
2813 (read_struct_type): Add FIXME comments where it needs work
2815 (read_huge_number): Add FIXME about overflows.
2816 (read_range_type): Add FIXME about comparing a long to 1<<32.
2818 * coffread.c: Minor changes to move things closer to the new
2819 regime with symtab.c and dbxread.c Major work is still needed
2822 * exec.c (exec_file_command): Remove old variables (see core.c
2824 (xfer_memory): If memory transfer is right at the end of a
2825 section, don't lose.
2827 * findvar.c (get_saved_register): If value is in a real
2828 register, LVAL is lval_register, not lval_memory.
2830 frame.h: Declare print_sel_frame and record_selected_frame.
2832 gdb-int.texinfo: New file, for GDB internals documentation.
2833 Very simple, unformatted doc of cleanups is there for now.
2835 gdbcore.h: Remove obsolete variables that described a.out
2836 section addresses and offsets. (See core.c above.)
2837 Declare fetch_core_registers and registers_fetched.
2839 getopt.c: Declare char *alloca(); even on SPARC.
2841 infcmd.c (run_command): Call target_kill rather than
2843 (step_command, next_command, stepi_command, nexti_command):
2844 Declare from_tty parameter even though we don't use it.
2845 (run_stack_dummy): argument BUFFER is a char array, not
2846 a pointer to REGISTER_TYPE.
2847 (finish_command): using_struct_return needed a value *,
2848 not a struct symbol *.
2850 * infptrace.c (child_xfer_memory): To avoid dependency on
2851 where sections are in memory, try PT_WRITE_D and if that fails,
2852 try PT_WRITE_I. Most Unixes don't care which you use.
2854 * infrun.c (step_resume_break_shadow): Change to array to
2855 match other breakpoint shadow storage.
2856 (clear_proceed_status): Pass address of bpstat to
2857 bpstat_clear, not the bpstat itself.
2858 (child_create_inferior): FIXME comment about if the child
2860 (start_inferior): Remove old function.
2861 (child_open): Use target_kill rather than kill_inferior.
2862 (wait_for_inferior): Ditto.
2863 (insert_step_breakpoint, remote_step_breakpoint): Use
2864 new step_resume_break_shadow.
2866 * inftarg.c (child_wait): If all child processes die,
2867 pretend that the one being waited for exited with signal 42.
2869 * main.c (command_line_input): When scanning for comments,
2870 don't coredump on unclosed quotes.
2871 (quit_command): Use target_kill rther than kill_inferior.
2872 (_initialize_main): Rename class_user from "user" to
2875 * printcmd.c (print_command_1): Initialize "fmt" if no format
2876 is specified by the user.
2877 (print_frame_args): Only add to args_printed if we are
2878 actually fetching args from the stack (avoiding undefined
2880 (_initialize_printcmd): Remove bogus \{ from string.
2882 * remote-eb.c (eb_open): Avoid coredump on no argument.
2884 * remote-nindy.c: Bring out of Intel environment into new
2885 target environment. Remove all conditional compilation on
2886 I80960. Massive hacking throughout.
2887 (nindy_xfer_inferior_memory): New routine stolen from
2889 (nindy_create_inferior): New routine pieced together, probably
2890 not quite working yet.
2891 (nindy_ops): New target_ops struct for nindy.
2893 * remote-vx.c: Use write_memory rather than target_write_memory
2894 to get error checking.
2895 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2897 (vx_create_inferior): Use target_terminal_ours...
2899 * signame.c (_initialize_signame): Always initialize, since
2900 we need the table for things other than psignal.
2902 * solib.c (solib_add): Use symbol_file_add, not add_file.
2903 (solib_address): Return boolean result rather than struct
2904 pointer which nobody else knows the type of.
2906 * sparc-tdep.c, valops.c: Use write_memory rather than
2907 target_write_memory, to get error checking.
2909 * stack.c (locals_info, catch_info, args_info,
2910 get_selected_block, frame_command, up_command): Use
2911 target_has_stack, rather than have_inferior_p or
2914 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2916 * symfile.h: New file, defining the interface between the
2917 generic and object-file-specific symbol reading code.
2919 * symtab.c: Move generic symbol-reading interface to symtab.c,
2920 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2921 table to map BFD targets to symbol-reading modules in GDB.
2922 Change index to strchr.
2923 (lookup_struct_elt_type): Use error() rather than hand-made
2924 simulations thereof.
2925 (lookup_partial_symbol): Speedup slightly when length == 0.
2926 (symbol_file_add): New function.
2927 (symbol_file_command): Call it.
2928 (symfile_open, symfile_init): New function.
2929 (add_file_target_command, add_file_addr_command): moved from
2932 * target.c (target_command): use target_kill.
2934 * target.h (target_files_info): Don't declare, never called
2937 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2938 files to determine stack end address.
2940 * valarith.c (value_x_binop, value_x_unop): Change error message
2941 to be more useful. Pass proper argument to value_struct_elt.
2943 * valops.c (value_assign): FIXME comment that long long
2944 bitfields will break here.
2946 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2947 Update `make saber_gdb' to work better.
2949 * TODO: A woman's work is never done.
2951 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2952 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2953 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2954 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2955 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2956 valops.c, valprint.c, exec.c: Lint.
2959 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2961 Continuing Intel 960 port merge of GDB.
2963 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2964 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2965 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2966 Wack over "make depend" so it handles files in subdirectories
2967 vx-share, nindy-share, bfd, and in the current directory.
2969 * blockframe.c (get_prev_frame_info): Remove fatal error
2970 if stack not defined.
2972 * core.c (core_open, core_detach): New functions that handle
2973 the old "core-file" command as "target core" and "detach" instead.
2974 (core_file_command): Call them.
2975 (core_xfer_memory): Use common routine xfer_memory.
2977 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2978 dbxread now uses bfd for everything but symbol reading itself.
2979 BFD internals are used to drag out the relevant file offsets.
2980 (partial_symbol_file_open): Change args all around for BFD.
2982 * symtab.c: Rename "value" to "val" everywhere, so we can
2984 (symbol_file_command): New command, moved from dbxread.c
2985 and coffread.c. It uses BFD to read the file, then vectors
2986 based on its type, to dbx or coff symbol readers.
2987 * symtab.h: Extern a few vars for symbol_file_command.
2989 * target.h: Breakpoint takes a char * save area, not a char **.
2991 * valprint.c (val_print): When unpacking bitfields, offset
2992 the address in gdb of the value, if it is declared with a shorter
2993 type. Remove the last "runtime kludge test" of host byte order.
2995 * utils.c: Remove old my_bfd_read routine.
2997 * stack.c (frame_info): Use target_has_stack. Print program counter
2998 register's actual name rather than "pc", since it's called the
2999 "ip" (instruction pointer) on the i960 (sigh).
3001 * target.c (target_command): Add command for selecting a target
3002 type and calling its open routine. This is used for initiating
3003 communication with a particular target, in a generic way.
3005 * tm-i960.h: Update for modern gdb. Remove semicolons from
3006 various macros. Handle reading struct return convention, and
3007 error-out attempts to return structs with the "return" command.
3008 Be sure gdb doesn't think we know how to call functions in the
3011 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
3012 to i960_xxx in lower case.
3013 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
3014 not being defined yet.
3016 * remote.c (remote_open): Call start_remote to initialize
3017 wait_for_inferior during open.
3018 (remote_xfer_inferior_memory): Return length written rather
3021 * remote-vx.c (target_command -> vx_open): Use new generic
3023 * remote-eb.c, inftarg.c, exec.c: ditto.
3025 * infrun.c: Fix comments.
3026 (attach_program -> child_open): Use new generic target command.
3027 (wait_for_inferior): Clear saved register values before target_wait,
3028 so target_wait can set some of them if convenient.
3030 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
3031 Return success indicator, not void.
3032 (child_xfer_memory): Avoid fetching initial word if we'll
3033 overwrite it anyway.
3035 * infcmd.c (attach_command): Use new generic target open routine.
3036 (_initialize_infcmd): Update doc on attach and detach commands.
3037 (do_registers_info): Merge in a byte-order problem as a FIXME
3040 * findvar.c (find_saved_register): Avoid problem in current frame.
3041 (read_relative_register): Ditto.
3042 (write_register): Convert byte order on the way out.
3044 * exec.c (file_command): Add.
3045 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
3046 (xfer_memory): Common function between core_xfer_memory and
3048 (exec_xfer_memory): Use it.
3050 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
3052 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
3053 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
3054 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
3056 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
3058 Merge Intel 960 port of gdb, continuing...
3060 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
3061 symbol_file_command): Pass from_tty arg to hush 'em up.
3063 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
3064 Add magic numbers for 960 COFF format.
3066 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
3068 Merge Intel 960 port of gdb, from Intel "1.2" release.
3070 CHANGE_LOG entries from their port, which was based on
3073 Thu Sep 6 11:02:22 PDT 1990
3074 Remove temp file if download is interrupted.
3076 Wed Aug 1 09:08:33 PDT 1990
3077 Now uses binary protocol to talk to NINDY.
3078 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
3079 Times out after 5 seconds when trying to talk to NINDY.
3081 Tue May 29 12:54:49 PDT 1990
3082 Added variable baud rate (-b switch).
3083 Source code reorganization.
3085 Thu Apr 26 11:09:55 PDT 1990
3086 More cleanup of batch mode; specifically, execute "-s", "-e", and
3087 "-se" switches as soon as they are encountered on the invocation line.
3089 Fri Apr 20 13:47:15 PDT 1990
3092 Thu Apr 19 09:54:28 PDT 1990
3093 Add 'reset' command.
3095 Wed Apr 18 09:48:07 PDT 1990
3096 After opening remote tty, wait for 1 second to go by without input
3097 from it before trying to talk to NINDY (fixes problems with the
3098 Heurikon HK80/V960E).
3100 Mon Apr 4 16:33:05 PDT 1990
3101 Some output was not being suppressed in 'batch' mode.
3103 Thu Mar 22 15:31:11 PST 1990
3104 Ask user if old symbol table should be deleted when new file is
3107 Allow user to run a program downloaded before gdb960 was brought up.
3109 Correct "exec-file" help message for i80960 context.
3111 Correct bug in calculating user space address: could occasionally
3112 corrupt user program.
3114 Make sure to zero low-order bits in rip's because of bug in 960CA
3115 A-step part: could cause operation faults when "next"ing across
3118 Correct bug that made it impossible to get source line numbers for
3119 code loaded at addresses higher than 0x7fffffff.
3121 Wed Jan 10 12:43:22 PST 1990
3122 Open remote tty for exclusive use.
3124 Fri Jan 5 12:14:42 PST 1990
3125 Correct disassembly (CA manual was right after all):
3126 opcode for sysctl is 0x659
3128 Mon Oct 23 12:03:04 PDT 1989
3129 Use G960BASE and G960BIN environment variables to find 'sx' utility.
3131 Mon Oct 16 14:15:09 PDT 1989
3132 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
3134 Mon Oct 2 15:56:31 PDT 1989
3136 Added 960CA disassembly support.
3138 To simplify maintenance:
3139 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
3141 - eliminated opcode.h: incorporates tables into i960-pinsn.c
3142 - moved 960-specific routines from i960-pinsn.c to i960-md.c
3143 - made disassembly interface identical to that in gdmp960.
3147 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
3149 * target.h: Allow targets to stack. Add target_has_memory,
3150 _registers, etc. Restructure memory access and "info files"
3151 to walk the target stack.
3152 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
3153 target.c: Change tables to match target.h.
3154 * inflow.c (child_mourn_inferior): pop child_ops.
3155 (generic_mourn_inferior): Use new has_stack flag.
3156 * infptrace.c (child_xfer_memory): New memory regime.
3157 * inftarg.c (child_files_info): New "info files" regime.
3158 * remote-eb.c: New memory regime, new info files.
3159 * remote-vx.c: New memory regime, new info files. Now use
3160 separate targets for VxWorks attachment to machine, and
3161 actually running a process under VxWorks, since one has
3162 stack & execution & regs and the other doesn't.
3163 * remote.c: New memory regime, new info files.
3164 * sparc-xdep.c (fetch_core-registers): New memory regime.
3165 * target.c: New routines and support for stacked targets,
3166 new memory regime, new info files regime.
3169 Generalize section handling for an arbitrary number of sections,
3170 including use of the new BFD (binary file) library.
3171 * gdbcore.h: Add struct section_table.
3172 * exec.c (build_section_table): Iterate all sections and
3173 record what gdb needs to know about them.
3174 (exec_command): Use it.
3175 (exec_xfer_memory): Use the table.
3176 (exec_files_info): Print the table.
3177 * core.c (core_file_command, core_xfer_memory, core_files_info):
3179 * source.c (find_source_lines): Use bfd_get_mtime.
3180 * dbxread.c: Quick changes to make it compile with new BFD.
3181 * utils.c (error): Avoid using bfd_error in generic routines.
3183 * core.c (core_fetch_registers): Get from the ".regs" section of
3185 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
3187 * inferior.h (attach_flag): Export.
3188 * infcmd.c (run_command): use new target_create_inferior.
3189 * infrun.c (child_create_inferior): Don't return result.
3190 * Makefile.dist (VERSION): 3.91.4.
3192 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
3194 * breakpoint.c (bpstat_num): Handle breakpoints which have
3195 since been deleted, such as temporary breakpoints.
3196 infcmd.c (program_info): ditto.
3198 * core.c (core_file_command): Display the frame where the core
3203 * remote-vx.c (target_command): Merge in target command from
3204 targ-vx.c. A few other cleanups.
3206 * TODO, Projects: Lots more stuff to do...
3208 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
3210 Massive changes to wall off the remote-debugging interface
3211 behind a function vector. The port to handle VxWorks targets
3212 is also part of this.
3214 All files: Replace references to renamed functions,
3215 remove references to remote_debugging, remove references to
3216 have_include_file, have_core_file in favor of target_has_stack,
3217 target_has_memory, etc.
3219 * Modularize the breakpoint interface.
3220 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
3221 a breakpoint instruction.
3222 breakpoint.c: struct breakpoint's shadow_contents now sized as
3224 (insert_breakpoints): Vector to target to install breakpoints.
3225 (remove_breakpoints): Vector to target here too.
3226 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
3227 sparc-tdep.c (single_step): Use new breakpoint interface for
3228 the single-step breakpoints.
3229 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
3230 New file, contains routines to insert and remove breakpoints by
3231 reading out the old contents and later replacing them. This is
3232 how ptrace breakpoints work, and many remote systems as well.
3234 * tm-vxworks68.h: New config file, overrides a few things for
3235 Wind River's preferences.
3237 * target.h: New file, for transfer vector used to talk to the
3238 inferior (child, attached, core, exec, remote, etc). All accesses
3239 to the thing being debugged should come through these vectors.
3240 target.c: New file, routines to handle transfer vector.
3241 (various files): Add transfer vectors XXX_ops for the various
3242 targets and pseudo-targets (core files, etc) we support.
3244 * breakpoint.c (bpstat_stop_status): Further explorations of
3245 watchpoints and why things don't work all the time.
3246 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3248 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3249 the local gdbinit if it doesn't already have it.
3251 * core.c (core_ops): add and install.
3252 Allow core debugging without exec file.
3254 * dbxread.c (free_and_init_header_files): Merge two fns.
3255 (end_symtab): Free named symbol table when a new version comes in.
3256 (read_dbx_symtab): Relocate all kinds of symbols with base
3257 address. First step toward handling different text, data, bss
3259 (add_file_addr_command): Renamed add_file_command.
3260 (add_file_command): Vector to remote handler.
3261 Add "load" as an alias for "add-file" command.
3263 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3264 non-returning functions.
3266 * exec.c: Add exec_ops, and push it as a target when an exec
3269 * infcmd.c (run_command): Pass executable file name and arg list
3270 separately when starting an inferior. Permit "run" when no exec
3271 file is specified, for VxWorks.
3272 (detach_command): Move to child_detach in inftarg.c.
3274 * inftarg.c: New file. Unix-child-specific routines, and the
3275 child_ops structure.
3277 * inferior.h (registers): Export "registers" as the way for
3278 target dependent register handlers to find gdb's local copy of
3279 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3280 since it is now used by places that want wait_for_inferior to
3281 handle the grunge but want to see every trap from the inferior.
3283 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3284 Eliminate remote_debugging hooks in terminal handling.
3286 * infrun.c: Replace start_inferior with child_create_inferior.
3287 Move all the hair of Unix shells and ptrace idiosyncracies into
3288 child_create_inferior, so remote handlers don't have to deal.
3289 Remove running_in_shell. Rename stop_after_attach to
3290 stop_soon_quietly, and use it in a few other places where we want
3291 to just call wait_for_inferior and get control back on the first
3292 trap. trap_expected now never takes a value > 1.
3293 (init_wait_for_inferior): Initialize static vars when a new
3296 main.c (gdbinit): Add new hook for .gdbinit file name, let
3297 it be overridden by config files as GDBINIT_FILENAME.
3298 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3299 Both of these are used for VxWorks gdb.
3301 mcheck.c: rename include file "gmalloc.c" to avoid problems
3302 with system include file "malloc.c".
3304 param-no-tm.h: New include file, same as param.h but does not
3305 include the default "tm.h" file. This is used in files where
3306 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3308 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3310 remote-vx.c: New file, VxWorks remote debugging support. Uses
3311 RPC routines that are shared with the target system, in directory
3314 remote.c: Vectorize remote interface.
3316 source.c: Globalize source_path, and make an alias "l" for "list"
3317 since we now have the "load" command.
3319 sparc-xdep.c: Use new param-no-tm.h.
3321 symmisc.c (free_named_symtab): Add new function from Wind River.
3322 However, ifdef it out for now while we think about what it should
3325 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3327 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3328 non-Unix-children handle this with their own code in the target
3331 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3332 source and target lists. Add vx-share to default list of include
3333 directories. Add new files to src and target lists: mem-break,
3334 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3335 ${srcdir} versions of munch and createtags are used.
3337 * valops.c (find_function_addr): Split out of call_function.
3338 (call_function_by_hand): Rename call_function; this function
3339 calls functions in the target by laboriously patching the target
3340 word-by-word with the right stack, args, regs, etc.
3343 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3345 Handle AMD 29000 a bit better.
3347 * remote-eb.c (readchar): Mask received char log to make it readable.
3348 (remote_start): Pass arguments down to executing program.
3349 Make startaddr unsigned.
3350 infrun.c (start_inferior): Accept args, pass them to
3352 infcmd.c (run_command): Pass args down to start_inferior.
3354 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3355 the target object file format.
3356 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3358 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3359 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3361 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3363 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3364 * TODO: We did a few things, we have more to do though.
3366 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3367 * inflow.c (inferior_died): Clear deferred stores.
3369 * Debug problems with dummy frames and calls to the inferior.
3370 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
3371 * sparc-tdep.c (do_restore_insn): Simplify.
3372 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3373 (sparc_push_dummy_frame): Simplify and fix what we push.
3374 (sparc_pop_frame): Slightly more hair here, deciding whether
3375 we are restoring a saved PC or returning to a return address in %i7.
3376 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3378 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3379 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3380 * obstack.h (chunkfun): ditto.
3381 * defs.h (xmalloc, xrealloc): ditto
3383 * utils.c (quit): Grab the terminal from the child if necessary.
3385 * inflow.c (term_status_command): Rename to term_info, change
3388 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3389 (is_delayed_branch): Speed up.
3390 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3391 Still missing some float ops, and needs testing.
3393 * Support for input and output radixes other than base 10
3394 * defs.h (input_radix, output_radix): Declare.
3395 * expread.y (yyparse, parse_number): Handle changes of input
3396 radix, and ambiguous names-or-numbers in radixes >10.
3397 * printcmd.c (print_scalar_formatted): Print formatted hex
3398 numbers in varying column widths.
3399 * valprint.c (val_print): Use output_format to print scalar ints.
3400 (set_input_radix, set_output_radix, set_radix): Create.
3401 (set_output_radix): Set output_format from output_radix.
3402 (_initialize_valprint): add `set radix' but leave the others off.
3404 * main.c (execute_command): Let stupid questions be turned off.
3405 (_initialize_main): Handle "set stupidity", etc.
3407 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3408 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3410 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3412 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3413 bfd stuff is still screwed up, but with some manual work, it
3416 * breakpoint.c (bpstat_do_actions): Start over if a command
3417 proceeds the inferior, since the inferior will have stopped and
3418 will need to have its new stop-actions taken care of.
3420 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3421 compiler fits, simplify it.
3423 * gdb.texinfo (directory command): Doc new dir command.
3424 source.c (directory_command): "dir" now puts things on the front
3425 of the path, moves dups up front, and handles multiple names
3426 on the command line, inserting each one in order. It also
3427 blows away cached line and full_filename info.
3429 * stack.c (backtrace_command): Skip "more stack frames follow"
3432 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3433 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3434 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3435 The only odd one was Gould NP1, which had defined vprintf to
3438 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3439 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3440 variable, inspect_it.
3441 valprint.c (print_string, val_print): Use the global inspect_it
3442 to indicate whether to print in Epoch style or normal style.
3444 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3446 * printcmd.c (call_command): add an alias for the "print" command
3447 which runs expressions and doesn't print the result if void.
3448 (print_command_1): implement it.
3450 * command.c: Remove #if 0'd code. Initialize all the fields
3451 in add_cmd (). Rename do_nothing_command to
3452 not_just_help_class_command, and make it externally visible.
3453 command.h: add user_commands to struct.
3454 * main.c (define_command): Don't overload c->function with a char
3455 string as well as a function pointer.
3457 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3458 calling convention of value_struct_elt () that got dropped in
3461 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3462 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3464 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3466 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3467 until a good time (e.g. when we are about to run the child),
3468 saving ptrace calls.
3469 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3470 * tm-sparc.h: define DO_DEFERRED_STORES.
3472 * sparc-xdep.c (store_inferior_registers): when storing float
3473 registers, don't store stack regs too. When storing the SP,
3474 however, DO store the stack regs too. This fixes a bug in which
3475 the dummy frame is not recognized when a call_function finishes,
3476 because its frame pointer (in the stack regs) was never
3478 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3479 even though we don't know how to read them from an inferior.
3480 valops.c (call_function): Comment about storing SP.
3482 * infrun.c (save_inferior_status): Save away the original bpstat
3483 chain so it can be restored later. Install the copied version for
3484 use by whoever saved the status. It will be blow away by
3485 restore_inferior_status, and the original chain restored. This is
3486 important for people who have pointers into the original.
3488 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3489 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3490 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3493 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3495 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3496 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3497 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3499 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3501 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3502 Store the baseclasses in a type struct starting from array element
3503 0 rather than from the unusual array element 1.
3505 dbxread.c: the above.
3506 (virtual_context): Add
3507 Read new debug information about which virtual function table
3508 a virtual function is from, and store it in fn_field.fcontext.
3510 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3511 TYPE_FN_FIELD_STATIC_P.
3513 symtab.c: the above.
3514 valops.c: the above. Handle pointer casts of object *'s.
3515 (search_struct_method): Add.
3516 (value_struct_elt): First arg is now a pointer to a value, and is
3519 valprint.c: the above.
3520 values.c (value_virtual_fn_field): Add type arg. Handle
3521 offsetting to the proper object when calling virtual fns.
3523 (baseclass_addr): Add valuep arg.
3525 * README: Document the current state of BFD config (missing).
3526 * TODO, ChangeLog, Makefile.dist: Roll version.
3527 * WHATS.NEW: Add summary of changes since 3.5.
3529 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3531 * dbxread.c (read_struct_type): Clear bit vectors whenever
3533 symtab.c (B_CLRALL): define.
3535 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3536 using == rather than =. Huh... This fixes the dreaded problem
3537 wherein builtin_type_int becomes TYPE_CODE_FLT.
3539 * core.c (info_files): Show the inferior pid.
3541 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3542 already knows how to look in the source directory.
3544 * Remove psymtab hair from many places. Remove duplicated code
3545 for searching symbol tables. Hide psymtabs from most places.
3546 Make it fast to get from a psymtab to its symtab.
3548 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3549 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3550 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3551 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3552 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3553 new symtab completely. New psymtabs get symtab pointer
3554 initialized to zero. Remove MI warning printf.
3555 symtab.h: Comments. Add psymtab to symtab pointer.
3556 (PSYMTAB_TO_SYMTAB): New macro.
3557 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3558 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3560 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3562 (print_frame_info): Avoid special-casing symbols that have not yet
3565 * source.c (open_source_file): Quick path if we have already
3566 located the source file by its full name.
3568 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3569 find_pc_psymtab. When a name is found in the misc function
3570 vector, search the symbol table for its mangled name, not the
3571 name that the user typed.
3573 * bfd.h: Fix missing comment terminators, make #endifs match.
3575 * valarith.c (value_less): Handle unsigned int comparisons.
3576 Add FIXME about pointer compares, which assume host and target
3577 pointers are the same.
3579 * command.c (do_nothing_command): lint
3580 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3581 fix comments on debug symbol format for visibility. Actually set
3582 visibility of symbols.
3583 main.c (echo_command): lint; use <readline/history.h>.
3584 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3585 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3586 pointing past end of allocated memory; saber complains.
3587 obstack.h: Declare the external functions that we use.
3588 valarith.h: use <string.h>
3589 solib.c (solib_add): lint.
3591 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3593 * main.c (initialize_main): Default info_verbose to off, now that
3594 symbol reading is fast.
3595 (quit_command): Avoid clobbering exec_bfd while quitting.
3597 * Initial BFD (binary file diddling library) merger:
3598 coffread.c: Change AOUTHDR to struct exe_hdr.
3600 core.c: initialize initialized data at compile time.
3601 (core_file_command): Move from coredep.c, convert to bfd.
3602 (xfer_core_file): Convert to bfd.
3603 exec.c (exec_file_command): use bfd routines.
3605 mips-tdep.c: Remove exec_file_command and friends.
3608 * coredep.c: (fetch_core_registers) Convert core_file_command to
3609 fetch_core_registers.
3610 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3612 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3613 (my_bfd_read): More bogosity, which I don't think we call.
3614 (program_name): Remove this atrocity asap!
3616 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3619 values.c: allocate_repeat_value was not clearing the
3620 optimized_out field.
3621 (value_static_field): minor stylistic fix (wrong macro was used).
3622 valops.c (value_struct_elt_for_address): didn't work for C++
3625 * signame.c (_initialize_signame): Initialize signal names once.
3627 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3628 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3629 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3631 * remote-eb.c: Support user-settable baud rates on the serial port.
3633 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3635 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3637 * tconfig/sun3os4: Remove warning about native assembler,
3638 since it also occurs in the xconfig file.
3640 * findvar.c (registers): Allocate some slop after `registers'
3641 to prevent stray accesses from trashing the next variable.
3643 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3644 on the sun-3, by changing the #ifdef from `sun3' (which is not
3645 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3646 vars, which happened to follow `registers' in the executable.
3648 * readline/history.c (history_search): Heed gcc-2's advice
3649 and parenthesize && inside ||).
3651 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3652 tm-29k.c: Insert FSF copyright headers.
3654 * remote-eb.c: Better comments.
3656 * Makefile.dist: Update to 3.91.6.
3657 * TODO: note PREPARE_TO_STORE problem.
3659 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3661 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3663 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3665 * infrun.c (wait_for_inferior, at end): Don't set up
3666 prev_* if the inferior no longer exists.
3668 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3669 CANNOT_EXECUTE_STACK.
3670 valops.c (call_function): Use it.
3672 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3674 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3675 infrun.c (wait_for_inferior, 2 places): Use it.
3677 * values.c (value_being_returned): Only use
3678 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3680 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3681 right thing for remote-eb.c.
3683 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3684 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3686 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3687 (FRAME_FIND_SAVED_REGS).
3689 * findvar.c ({fetch,store}_registers): Check for
3690 REMOTE_{FETCH_STORE}_REGISTER macro.
3692 * findvar.c (get_saved_register): Add argument lval and
3693 change meaning of argument addr.
3694 findvar.c: Change calls to get_saved_register to reflect
3695 new calling convention.
3696 valops.c (value_assign): Use get_saved_register instead of
3697 find_saved_register.
3699 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3701 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3702 an (uninitialized) pointer to one. Use "&" when passing it
3705 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3707 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3710 * coffread.c (symbol_file_command): Put semicolon after
3712 Put safe_to_init_tdesc_context in #if defined (TDESC).
3713 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3714 coffread.c: #include <sys/stat.h>.
3715 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3716 Add missing ')' in check for "lc%" and friends. Remove
3718 Declare read_one_sym() at top of file.
3719 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3720 MC68WRMAGIC can have the same value without causing a duplicate
3723 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3725 * Allow a Makefile to be built without building the
3726 tm and xm file links that screw up builds in subdirectories.
3727 This is done with `config.gdb none', then you can do things
3728 like `make gdb.tar.Z'.
3729 * tconfig/none: Config file for no target system
3730 * xconfig/none: Config file for no host system
3731 * config.gdb: If no TM or XM files are called out by the
3732 host or target file, don't make links for them.
3734 * cplus-dem.c: Add documentation.
3736 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3737 simple error, so the user's gdb doesn't crash due to some object
3738 file problem (e.g. somebody is rebuilding the file out from under
3741 * printcmd.c (print_address_symbolic): demangle the symbol.
3743 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3744 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3745 (alldeps.mak): sort and uniq all results from this; duplicates
3746 hose gdb.tar.Z link building. Remove RCS files from
3747 tconfig and xconfig. Add config files for sun386. Add
3748 a few odd files to OTHERS and HFILES.
3750 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3752 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3753 Roll version number to 3.91.5. Make lint work in bindir.
3755 * README: Document cross-debugging and new file structure.
3757 * blockframe.c: Lint. Include "value.h" to declare read_register.
3758 (find_pc_partial_function): remove duplicate line.
3760 * command.h: Lint. Declare error_no_arg and dont_repeat.
3762 * tm-news.h: Remove inadvertently duplicated stuff.
3764 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3765 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3767 * config.gdb: Allow `config.gdb host target' form. Clean
3768 up previous change that printed bogus messages when you just said
3771 * core.c: #include "command.h" for lint.
3774 * main.c: Remove some casts of enums. Lint.
3781 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3783 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3784 read it from memory. This will allow us to save ptrace calls
3785 eventually. Changed caller single_step too.
3787 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3788 that we aren't going to use, saving many ptrace calls, especially
3789 when watchpointing or single stepping. Use some #define's for
3791 (store_inferior_registers): Ditto.
3792 (core_file_command): Use some #define's for constants.
3794 * tm-sparc.h: Add #define's for some register numbers, so we
3795 can eliminate the use of random constants in sparc-xdep.c.
3797 * stack.c (frame_command, print_frame_info, up_command,
3798 down_command) Remove frame_changed, since it
3799 causes a bug and doesn't seem to do anything useful. In some
3800 places it was used as a flag, in others as a stack level (?).
3802 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3803 default is to use the portable (vprintf) version rather than the
3805 * xm-news.h (MISSING_VPRINTF): Add.
3807 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3809 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3811 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3812 about linking debugged programs -Bstatic in the sun?os4 config
3813 files in tconfig and xconfig subdirectories.
3815 * main.c (main): Remove unreached exit(0) now that we exit
3818 * Create TODO file for online bug list. There are too many
3819 "little" bugs to keep track of on paper.
3821 * Change Projects file to refer to bug-gdb@cygnus.com
3822 rather than kingdon@ai.
3824 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3826 * Makefile.dist (VERSION): 3.91.4 now.
3828 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3829 (condense_misc_bunches): Add sanity check that misc_count is
3830 the same as the number of symbols in the bunch.
3832 * coffread.c: rename init_misc_bunches. Pass an argument
3833 to condense_misc_bunches (a zero).
3835 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3836 every time we are called; don't rely on our caller to do it.
3837 (add_file): Remove call to init_misc_bunches.
3839 * mipsread.c: Only warn, don't error, if unknown symbol types.
3840 This keeps an old gdb from falling on its face if it sees newly
3841 extended symbol info. Rename init_misc_bunches.
3843 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3845 * Merge in changes from Per Bothner for DECstations and other
3846 MIPS stuff. The rest is Bothner speaking:
3848 The next message is a merger of Alessando Forin's mips port with
3849 mine. I've tried to use my good if biased judgment to get
3850 the best of both. It *does* need testing.
3852 Some of the changes are general, *not* mips-specific.
3855 Didn't believe in little-endian bit order.
3856 There are still inconsistencies about whether flags
3857 like BITS_BIG_ENDIAN are integer (#if ...) or
3858 boolean (#ifdef ...). I tried to paper over them.
3860 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3861 Moved some misc_function code that was common to
3862 {dbx,coff,mips}read.c to symtab.c.
3863 In the process, I think I cleaned things up a bit.
3864 At the same time, moved obsavestring and obconcat to symtab.c.
3867 Removed obsolete condense_addl_misc_bunches (use
3868 condense_misc_bunches(1) instead).
3871 Needed to include <sys/dir>, at least on DECstations.
3873 valops.c, mips-tdep.c, tm-mips.h:
3874 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3875 conventions (when STACK_ALIGN is insufficient).
3876 Needed on mips, where doubles need 8-byte alignment,
3877 but ints only need 4.
3880 Removed cruft that was not being used.
3881 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3884 Print $ before register-names (I think that makes things a little
3886 Never print two instructions, even if one delays.
3887 Removed hex-disassemble set_cmd. (This is not mips-specific,
3888 so I think the argument is whether it is generally worthwhile or not.
3889 I'm inclined to think not, given how easy it is to
3890 convert between radixes in gdb.)
3893 This is basically Alessando's code.
3894 It doesn't use obstacks; I changed it to use obstacks
3895 in a few minor places where using malloc causes a
3896 memory leak. (Probably, more places could/should be changed.)
3897 I added record_misc_function where it was missing.
3898 In symbol_file_command and add_file_command, I tried
3899 to make the code consistent with more recent versions.
3900 Minor sylistic changes in parse_procedure.
3901 Make a .gdbinfo. psuedo-symbol point back to the real
3902 procedure symbol (using the isym field).
3905 This is basically from my port, but with a lot of details
3906 and a number of routines merged in from Alessando's version.
3907 I basically used my code "raw" backtrace (use heuristics
3908 from the actual code, rather than symbol table info) - though
3909 the idea is Alessandro's. I feel my code is a little cleaner
3910 here, particularly in being a little more flexible, such as being
3911 able to handle gcc-produced code (which it now can).
3912 It also doesn't do frame caching (which is not useful
3913 more recent gdb versions).
3914 I also used my code for push_/pop_dummy, more or less.
3915 I tried to incorporate AF's code for testing sigtramp
3916 while backtracing; I probably got it wrong.
3917 Added mips_print_register, which tries to scrunch as much
3918 information as possible on a screen...
3919 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3920 under mips-pinsn.c), I don't see anything mips-specific here,
3921 and I don't see it being all that useful anyway.
3924 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3925 Use more register names (rather than hard-cases numbers).
3927 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3929 * Hack up 3.90.11 changes:
3931 * Makefile.dist (depend): parameterize $(GCC).
3932 Add solib.c and solib.o.
3933 (readline): Fix vpath for both absolute or relative SRCDIR.
3935 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3936 Also, let the part I didn't understand at least compile so
3937 I can test the rest. FIXME.
3939 * dbxread.c: Fix thinko using strcmp.
3940 (init_psymbol_list): declare static.
3941 (partial_symbol_file_open): Comment cleanups better, avoid
3942 cleaning up the string table since the caller will do that.
3943 Move the stat for mod time into symbol_file_command, temporarily.
3944 (There should be a mod time for each symbol file, eventually,
3945 to control its rereading. FIXME.)
3947 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3948 SunOS, which gives error for shared libs otherwise. (From
3949 Schaefer, probably FIXME needs work for portability.)
3951 * solib.c: Move #include "param.h" to work.
3952 Lowercase all the Uppercase Letters In the Messages.
3953 (find_solib): Clean up inferior_so_name for debug printouts.
3954 Allow no argument, to mean all shared libraries.
3956 * symmisc.c: include param.h to get CLEAR_SOLIB.
3958 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3960 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
3961 to 3.90.11. ChangeLog entries below are from this.
3963 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3967 * Makefile.dist (HFILES): Add tm-sunos.h.
3969 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3973 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
3975 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
3977 * sparc-opcode.h Added single-operand version of rett.
3979 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3981 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
3982 Put parens around gcc_p in expansion.
3984 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3986 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
3988 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3990 * Changes for Sun shared libraries:
3991 blockframe.c (find_pc_partial_function): If a non-text symbol
3992 is found, set *address = pc - FUNCTION_START_OFFSET.
3993 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
3994 Disable breakpoints instead of giving an error.
3995 source.c (select_source_symtab): Initialize cs_pst.
3996 symmisc.c: Call CLEAR_SOLIB if defined.
3997 symtab.h: Make text{low,high} CORE_ADDR not int.
3998 (psymtab): New field addr.
4000 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
4001 (record_misc_function): Give correct type for N_DATA symbols.
4002 (condense_misc_bunches): do "misc_function_count = j" regardless
4004 Take code which is shared between symbol_file_command and
4005 add_file_command and put it into partial_symbol_file_{open,read}.
4006 Split add_file_command into add_file_command and add_file.
4007 Make psymtab_to_symtab read in the string table if the file
4009 Two new parameters to read_dbx_symtab and start_psymtab.
4010 tm-sunos.h: New file.
4012 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4014 * infcmd.c: Change cont_command to continue_command and "cont"
4017 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4019 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
4021 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
4023 * values.c (USE_STRUCT_CONVENTION): Check for structures of
4024 size 1,2,4,8 rather than size < 8.
4026 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
4027 as necessary, not just once.
4029 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
4031 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4033 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
4035 * tm-news.h: Add CALL_DUMMY_*.
4037 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
4039 * config.gdb: In list_host, list_target, use ${i}, not $i.
4041 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4043 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
4045 * sparc-opcode.h: Change all store floating-point state register
4046 instructions to have the right match & lose fields.
4048 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4050 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
4052 config.gdb: If srcdir != ., create readline directory and
4053 copy a makefile into it.
4055 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
4056 consistency with POSIX.
4058 * breakpoint.c (bpstat_stop_status): Disable watchpoint
4059 when we exit its exp_valid_block.
4061 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
4063 * Makefile.dist: Bump version to 3.91.3.
4065 * Clean up handling of breakpoint commands (somewhat).
4066 Prompted by Tiemann bug report "cont 10" doesn't work any more.
4068 inferior.h: Add breakpoint_proceeded to inferior status struct
4069 and globals; save it and restore it.
4070 (clear_breakpoint_commands): Cleanup, remove old #define.
4072 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
4073 (save_inferior_status, restore_inferior_status): handle it also.
4074 (proceed): Remove earlier code that set breakpoint_proceeded.
4075 It is now set only in clear_proceed_status.
4076 (clear_proceed_status): Cleanup, use bpstat_clear rather
4077 than clear_breakpoint_commands. No callers need the stop_bpstat
4078 between clear_proceed_status and proceed.
4080 infcmd.c: Add breakpoint_proceeded definition and comment.
4081 (cont_command, jump_command, signal_command): Move call to
4082 clear_proceed_status right next to call to proceed.
4084 breakpoint.c (bpstat_do_actions): Avoid clobbering our
4085 caller's argument while running down the chain of breakpoints.
4086 Use new variable "breakpoint_proceeded" to determine when
4087 a command that it executes moves the inferior past the
4089 (bpstat_clear): Handle NULL argument.
4090 (bpstat_clear_actions): Avoid useless call to
4091 breakpoint_auto_delete.
4092 (delete_breakpoint): Clean up bpstat's that are pointing to
4093 the deleted breakpoint from the stop_bpstat chain.
4094 (breakpoint_auto_delete): Simplify.
4096 * Clean up handling of EOF, error on stdin, etc. This was
4097 prompted by a network problem that caused gdb to go into an
4098 infinite loop filling up its malloc'd memory.
4100 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
4101 not clear_breakpoints_commands, which is now gone.
4102 (main): If command_loop returns (e.g. from EOF on stdin), do
4103 a quit_command (looping back to command_loop if quit_command
4104 doesn't really quit).
4105 (command_loop): check result from command_line_input and
4106 exit if it returns NULL, rather than passing the NULL to
4108 (gdb_readline): Free malloc'd result space before returning
4111 * utils.c (query): Handle C-d to mean "yes", just as if the
4112 input was not a terminal. Also avoid infinite loop if EOF
4113 occurs in mid-input-line before newline. This allows
4114 query to be used at EOF on stdin with reasonable results.
4116 * infrun.c (proceed): Set breakpoint_proceeded.
4118 * values.c (value_as_long): Avoid infinite recursion for enums.
4119 (_initialize_values): Fix typo in help msg (kingdon).
4121 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
4122 RL_LIB for linking. This allows -lreadline for linking
4123 and nothing for dependencies, once readline is a real library.
4125 * config.gdb: Jim Kingdon: give useful error message if the
4126 host or target type is not recognized.
4128 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
4129 it just defines it. Dumb, but deal with it.
4131 * Jim Kingdon suggests:
4132 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
4134 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
4136 * Makefile.dist (VERSION): Bump version # to 3.91.2.
4138 * Clean up Bothner's changes.
4140 * blockframe.c (clear_pc_function_cache): New function.
4141 * blockframe.c: remake cache_pc_function_* static.
4142 * dbxread.c (symbol_file_command): remove references to
4143 cache_pc_function_* variables.
4144 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
4145 * printcmd.c: Avoid kludging a global variable (addressprint)
4146 to avoid printing the address of a string twice. Instead,
4147 pass the format letter 's' down low enough that it can be seen
4148 to avoid this problem.
4149 (print_formatted): Pass format arg to value_print.
4150 (restore_addressprint): Remove function.
4151 (do_examine): Avoid hacking addressprint, cleanups and such.
4152 (print_frame_args): Add a comment to a Bothner change.
4153 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
4154 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
4155 to wipe out the values cached in blockframe.c.
4156 * symtab.c (find_method): Add comment saying how big you must
4157 allocate to be "big enough". Per being terse again.
4158 * valprint.c (val_print): Handle format letter "s" to print
4159 strings without addresses. Add comment to vtbl printing code
4160 which casts with wild abandon. Rearrange reference-printing
4162 @0xaddr: value (print w/addressprint)
4163 value (print w/~addressprint)
4164 @0xaddr (parameter lists w/addressprint)
4165 or nothing (parameter lists w/o addressprint)
4167 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
4169 * Merge more changes from Per Bothner:
4171 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
4172 annoying) that I tried to improve it. Here are my suggestions.
4174 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
4177 Do automatic de-reference when taking the address of a reference.
4179 Don't deref_ref when printing parameter lists.
4181 More attempts at treating refernences properly.
4183 In val_print, if deref_ref==0, don't print dangling " = ".
4185 Add COERCE_REF macro, which de-references an REF.
4187 * Merge changes from Per Bothner:
4189 * Fixed (Sony news)-specific configuration problems.
4190 * Fixed other problems with using vanilla pcc and libc (enum problems;
4191 assumption that vsprintf exists).
4192 * Some major speed-ups (finc_pc_partial_function now caches a match;
4193 parsing avoids duplicate symbol_lookup calls).
4194 * Changed handling of baseclasses (no longer use baseclasses field
4195 of struct type, use the first n_baseclasses fields instead).
4196 * Various minor changes/fixes, most C++-related.
4199 Cache the most previous match from find_pc_partial_function.
4200 (Save both low and high ends of matching function's pc range.)
4201 This speeds up the loop of infrun.c:wait_for_inferior quite
4202 a bit, and makes step/next commands much zippier.
4204 Added an enum->int cast (otherwise, some compilers barf).
4206 No longer set baseclass offset to 0, since multiple
4207 inheritance now mostly works.
4208 Added a number of casts, to shut up compiler warnings
4209 (after stabs where made enums, not ints).
4210 When discarding a symbol table (in symbol_file_command),
4211 must clear the cache introduced in blockframe.c.
4212 Don't convert $vtbl_ptr_type to vtbl any more.
4213 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
4214 Mask off sign bit emitted by g++ for virtual table offset.
4215 Set voffset to -1 (not 1) for static member functions.
4217 Changed parsing/lexing of names to avoid doing symbol lookup twice
4218 (once when lexing to determine symbol class, once for real).
4219 Now only call symbol_lookup once. Fields of 'this' win especially big.
4221 Subpress printing addr twice in the case of 'x/s addr'.
4223 lookup_basetype_type is no longer used.
4224 Add find_methods as recursive helper function to decode_line_1.
4225 This allows multiple inheritance to work.
4226 Also, once one or more matches has been found, do not look in
4227 base-classes. (Baseclass methods would be overridden, anyway.)
4229 Removed baseclasses array in struct type.
4230 Instead of using baseclasses[i], use fields[i-1].
4231 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
4232 Changed sign convention of voffset (previous was inconsistent).
4234 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4236 Used to assume existence of vsprintf. Re-written to not need it
4237 if HAVE_VPRINTF is undefined.
4239 typecmp was too pessimistic. Made it less so.
4241 Don't print space after address.
4242 If vtable points to a misc symbol (with 0 offset), print it,
4243 since that indicates the actual class of the object.
4244 Changed ype_print_derivation_info to use new inheritance
4245 scheme (without baseclasses vector).
4247 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4248 Also, changes needed because TYPE_BASECLASSES were removed.
4250 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4252 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4255 If there is no path set, and the symbols don't indicate what directory
4256 a file was compiled in, look in the current directory. But either
4257 a path or a known compilation directory will prevent this.
4260 Three independent bug fixes:
4261 * Remove the #if 0 block that breaks some stuff.
4262 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4263 adapt gdb to either SunOS 4.0.* or 4.1.
4264 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4267 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4270 (type_print) Demangle the name being printed.
4271 (type_print_base) Handle botched demangling without coredump (tiemann).
4274 (check_stub_method): Document routine.
4275 (tiemann) fix bug for no-arg functions
4276 Avoid clobbering beyond end of malloc'd storage.
4277 Terminate the argument list properly.
4279 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4281 * Changes merged by John Gilmore:
4284 In breakpoint_1, use new print_address_symbolic instead
4285 of find_pc_partial_function. (This forces use of assembler-level
4286 addresses, and avoids misleading non-mangled source-level names.)
4288 Generalize ansi argument such that -1 means skip arglist totally.
4289 Removed global variable print_ansi_qualifiers (which made
4290 code non-reentrant), in favor of extra explicit arguments
4291 to internal routines.
4293 Add new helper function print_address_symbolic.
4294 Use find_pc_misc_function instead of find_pc_partial_function
4295 (since we want assembler-level symbols here).
4297 Print unknown function as just "f (...)", not "f (...) (...)".
4298 Use new fputs_demangled explicitly.
4300 Fixed a typing violation (problem: value.h cannot be imported
4301 without renaming many variable in this file).
4302 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4303 decode_line_1: Moved forward some never-reached code.
4304 Made decode_line_2 skip function prologues correctly.
4306 fputs_filtered should not demangle by default.
4307 Add new fputs_demangled to demangle on demand..
4309 Change value_struct_elt to use value_primitive_field (using recursive
4310 utility function search_struct_field). This allows foo.bar to work
4311 for multiple inheritance (so far only for data fields).
4312 Change check_field in the same way (recursive helper function
4313 to support multiple inheritance).
4314 (Note: there are more of these problems that I haven't fixed.
4315 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4316 value_of_this: 'this' symbol name is now just "this", note "$this".
4318 Don't print static members.
4319 Avoid printing "members of <type>" if there are none.
4320 Simplified type_print_derivation_info by merging duplicate code.
4321 Remove useless blank lines in type_print_base (ptype command).
4323 Added declaration of new routine value_primitive_field.
4325 Added value_primitive_field which is generalized version of
4326 value_field that can handle multiple inheritance (non-zero offsets etc).
4327 Re-implemented value_field to call value_primitive_field.
4329 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
4331 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4332 delete the whole environment. Karl Berry reported the bug.
4333 * source.c - fix openp to avoid //'s in filenames, which
4334 trigger an Emacs bug causing it to not be able to find files
4335 when running gdb in a window.
4336 * dbxread.c - zap the #if 0 that botches the add-file code.
4337 It seems to work a lot better without all the code commented out.
4339 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
4341 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
4344 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
4346 * Makefile - added a ${CFLAGS} to a couple of entries,
4347 added remote-sa.sparc.c
4348 * added remote.sa-sparc.c, a modification of remote.c
4349 which conducts a dialog directly with the SparcStation prom.
4350 * breakpoint.c, infrun.c, sparcdep.c added
4351 remote_insert_breakpoint(), and remote_remove_breakpoint()
4352 to breakpoint.c instead of directly writing breakpoint instructions.
4353 * sparcdep.c on remote_debugging,there is no need
4354 to remove signle step breakpoint instructions.
4355 * main.c added "-epoch" flag and "int epoch_interface" to main.c
4357 * printcmd.c - epoch interface sends lisp expressions to open up
4358 epoch windows on inspection.
4359 * valprint.c - added arrayprint, and addressprint and made adding
4360 format controls easier
4361 * wait.h added a couple of undef's because we were getting
4362 complaints about WSTOPSIG and WTERMSIG begin redefined.
4365 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
4367 * symtab.c (decode_line_1): Add support for handling method stubs
4368 in the type information.
4370 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
4372 * values.c (baseclass_addr): Run loop from INDEX+1 to
4373 N_BASECLASSES; otherwise, we can still get into a loop.
4374 @@ This should be restructured to use a cleaner search strategy.
4376 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
4378 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
4379 abbreviation "Tt" for tags which have the same name as their
4382 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
4384 * symtab.c (list_symbols): add ability to set breakpoints on all
4385 the functions which match a particular regular expression.
4387 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
4389 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
4390 should print ANSI qualifiers (such as `const' and `volatile').
4391 All callers changed to call with ANSI == 1, except from
4392 `check_method_stub', which uses old-style syntax.
4394 * symseg.h (struct fn_field): Remove unneccessary `args' field.
4395 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
4397 * values.c (check_stub_method): New function.
4399 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
4401 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
4402 * valprint (type_print_base): Ditto.
4404 * symtab.c (gdb_mangle_typename): New function.
4406 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
4408 * breakpoint.c (catch_command): New function. Provides a
4409 mechanism to set breakpoints based on catch clauses.
4410 (disable_catch): Similar, but disables breakpoints on catch
4412 (delete_catch): Similar, but deleted breakpoints on catch clauses.
4414 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
4416 * blockframe.c (blockvector_for_pc): New function.
4417 * blockframe.c (block_for_pc): Changed to call
4418 `blockvector_for_pc' and get the block itself.
4420 * stack.c (catch_info): New function. Prints info about
4421 exceptions which can be caught in the current frame.
4422 * stack.c (print_frame_label_vars): New function. Similar to
4423 `print_frame_local_vars'.
4424 * stack.c (print_block_frame_labels): Prints out labels that are
4425 defined in this frame. These labels are exceptions that can be
4428 * dbxread.c: Updated to handle N_CATCH symtab types.
4430 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
4432 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
4433 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
4434 when printing the type.
4436 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
4438 * valprint.c (val_print): Use `baseclass_addr' to access the
4439 baseclasses pointed to via the derived class object at VALADDR.
4441 * values.c (baseclass_addr): New function. Casts derived pointers
4442 to baseclass pointers taking virtual baseclasses and multiple
4443 inheritance into account.
4445 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4449 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4451 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
4452 exp_valid_block field correctly.
4454 * infrun.c (wait_for_inferior): When checking "don't even think
4455 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
4456 also check step_resume_breakpoint.
4457 Insert breakpoints and continue (not step) if
4458 step_resume_break_address != NULL, even if another_trap.
4459 If trap_expected and we enter sigtramp, then set up a
4461 If trap_expected is set when we hit the step_resume_break,
4463 When calling resume and trap_expected says tell resume to step
4464 (2 places), also check step_resume_break_address.
4466 * infrun.c (wait_for_inferior): Don't set
4467 prev_{pc,sp,func_{start,name}} before calling wait ().
4468 Do set them after exiting loop.
4469 Move their declarations outside functions.
4470 (start_inferior): Initialize them.
4472 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4474 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
4475 Restore old code which distinguishes between trap_expected and
4476 running_in_shell, just make the latter take any non-TRAP signal,
4479 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
4481 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
4482 xconfig/3b1 (CC,PINSN_CC): Define.
4484 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.
4488 * breakpoint.c (bpstat_stop_status),
4489 infrun.c (wait_for_inferior) [SHIFT_INST_REGS]: New code.
4491 * param.h, tm-88k.h: Define ADDR_BITS_*.
4492 infcmd.c (jump_command, read_pc), infrun.c (wait_for_inferior),
4493 printcmd.c (do_one_display): Use them.
4495 * utils.c: Split #ifdef USG into a USG_UTILS and a QUEUE_MISSING.
