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

645 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
646 symtab.h, target.c, target.h: Lint.
647 * core.c: setup and select frame after reading shared libs,
648 else reading shared libs will clobber them. Lint.
649 * utils.c (error): Force out any buffered wrap text.
651 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
653 * remote.c: Remove decls of memory_insert_breakpoint
654 and memory_remove_breakpoint, no longer used. (Suggestion of
657 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
658 to make it easier to interface to "configure"'d libraries.
660 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
662 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
663 aliases for set/show print.

1167 New function to give correct error message.
1169 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

1172 target.c: Add target_preopen and target_command.
1174 (add_target): Call add_cmd and mess with targetlist->doc.
1175 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
1176 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.

1201 * symmisc.c (same): same.
1202 (free_symtab): Make non-static.
1203 * symtab.h (free_symtab): Declare as exported void fn now.
1204 * dbxread.c (end_symtab, end_psymtab): Change comments.
1205 (initialize_dbxread): Call dbx_new_init() in case the first
1206 command is add-symbols.
1207 * target.c (dummy_target): Permit add_syms_addr_command.
1209 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1211 Permit symbols to be superseded when new symbol files have
1212 been read in, particularly for VxWorks.
1214 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
1215 to the main file, as well as to include files. Also, put global
1216 functions into the global psymtab, to make "i fun" work.
1217 (end_psymtab): Free named symtabs and psymtabs for a file, once a
1218 new psymtab for it has been read.
1219 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
1220 a file, once a new symtab has been read for it.
1221 * mipsread.c: FIXME. We need to do the same for MIPS, but it
1222 looks harder to determine the top-level block before it's been
1223 queued to the psymtab list.
1225 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
1226 If we have wiped out any old symbol tables, clean up at end of
1228 (symbol_file_command): Don't reference symfile_fns if it's zero.
1230 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
1231 defines for the blocks of a blockvector that contain global and
1232 file-static symbols and the first of the smaller scope contours.
1233 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
1234 decode_line_1, make_symbol_completion_list): Use the above.
1235 * coffread.c (end_symtab, patch_opaque_types): Ditto.
1236 * dbxread.c (end_symtab): Ditto.
1237 * expread.y (block): Ditto.
1238 * mipsread.c (throughout): Ditto.
1239 * symmisc.c (free_named_symtabs): Ditto.
1241 * symtab.c (list_symbols): Process the first symbol of the
1242 static psymbols list.
1243 (types_info): Restore this function from its untimely #if 0.
1244 It's not perfect, but it is better than nothing.
1245 (_initialize_symtab): Restore "info types".
1247 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1249 * m68k-stub.c: Remote stub for 680x0's, created from
1250 rem-m68k.shar (which is removed).
1251 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
1252 Remove RCS log stuff now that we use CVS and it blows our diffs.
1254 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1256 * symmisc.c (free_named_symtab): Make it work, in its current
1257 kludgy fashion. Change result to indicate if we blew away bkpts.
1258 * dbxread.c (end_symtab): Accumulate result from
1259 free_named_symtab and print warning if we blew user's state.
1260 * symfile.h: free_named_symtab now returns an int.
1262 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1264 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
1265 is the first symbol read, even if not mainline.
1266 (dbx_psymtab_to_symtab): symfile might be zero, cope.
1267 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1268 (set_section_command): New command ("section xxx yyy" -- should
1269 be renamed to "set section xxx yyy" FIXME) which sets the
1270 base address of a section of the exec file, overriding the
1271 virtual address that BFD reports.
1273 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1275 * exec.c: Add add_syms_addr_command to exec_ops, so you can
1276 load symbols at any address while examining an exec file.
1278 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1280 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1281 for printing the float info is host-dependent, not
1282 target-dependent. FIXME.
1283 * i386-pinsn.c: Move #includes to top, remove useless ones.
1284 * i386-tdep.c: Don't bother including <.../reg.h> since we
1285 don't use it (and it doesn't exist on host systems).
1287 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1288 Convert negative numbers properly.
1289 (ieee_test): Make numbers really random; fix format arg.
1291 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1292 * core.c (core_detach): Unpush core_ops, which might not be on
1293 top. We used to just pop the top, which broke things. Don't
1294 need dont_repeat() any more.
1295 (core_file_command): Psst! Don't repeat it.
1296 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1297 * expprint.c (print_subexp): Avoid switch fallthru on
1298 BINOP_ASSIGN_MODIFY, so we can print += and such.
1299 * frame.h: Fix typo.
1300 * inflow.c (kill_command): After killing inferior, print our
1301 current frame in the core file, if we have one.
1302 (generic_mourn_inferior): When inferior dies, either select
1303 the current frame (in the new target, e.g. core file), or
1304 set both the current and selected frames to NULL.
1306 Changes from Peter Schauer.
1308 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1310 * Make all file names fit in 14 characters (sigh and damn!):
1311 mv hp300hpux-xdep.c hp300ux-xdep.c
1312 mv symmetry-xdep.c symm-xdep.c
1313 mv symmetry-tdep.c symm-tdep.c
1314 mv convex-opcode.h convx-opcode.h
1315 mv tm-vxworks960.h tm-vx960.h
1316 mv tm-vxworks68.h tm-vx68.h
1317 mv Makefile.srcdir Makefile.sdir
1318 mv gdb-int.texinfo gdbint.texinfo
1319 mv remote-sa.m68k.shar rem-m68k.shar
1320 mv remote-multi.shar rem-multi.shar
1321 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1322 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1323 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1326 * command.c (user_info_1, user_info): New command for listing
1327 the user-defined commands.
1329 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1331 * dbxread.c (really_free_pendings): Clear file_symbols
1332 and global_symbols after freeing them; otherwise, running
1333 this function twice (if it appears twice on the cleanup
1334 chain), we try to free things twice.
1336 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1337 based on text_addr (the address of text in core), not on addr (the
1338 offset between text in the .o file and in core). This change
1339 is from Peter Schauer.
1341 * main.c: Define ALL_CLEANUPS as a cast of zero.
1342 (return_to_top_level): Use it.
1343 (main): Do all cleanups after each command run as part
1344 of the gdb startup sequence. Also do all cleanups before
1345 entering the command loop, and every time we exit the command
1346 loop and reenter. Before, the cleanups from the startup sequence
1347 were being left undone until the first error!
1348 (command_loop): Rename do_nothing cleanup to command_loop_marker
1349 so we can see it easily when examining the cleanup chain.
1350 (init_signals): Add another do_nothing for signal handling.
1351 (quit_command): Only try to kill target if it has execution.
1352 Problems in the target stack got us into a state where
1353 inferior_pid was nonzero but none of the targets had execution.
1354 In this state you couldn't exit gdb.
1356 * dbxread.c: Two changes from Peter Schauer.
1357 (echo_command): Fflush output after an echo command.
1358 (show_history): Pass all args to cmd_show_list.
1360 * utils.c (init_malloc): Call mtrace to turn on tracing
1361 if the environment variable MALLOC_TRACE is set to a file name.
1362 * mtrace.c: Add source file which provides a log of every malloc,
1363 free, and realloc to a trace file.
1364 * mtrace.awk: Add source file which analyzes the trace file.
1365 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1366 (VERSION): Roll to 3.94.3.
1368 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1369 (check_duplicates): Don't bother with watchpoints.
1370 (set_raw_breakpoint): Comment about danger of this routine.
1371 (watch_command): Parse and eval all args before calling
1374 * solib.c (find_solib): Avoid error in referencing memory to
1375 see if any more shared libraries have been added. This is
1376 particularly useful if the target has terminated. Bug reported
1379 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1380 in bringing up 3.94.2 on the Sun-3.
1382 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1383 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1384 expression (in scope) before reenabling watchpoint.
1385 * signame.c (init_sigs): Add missing declaration of i, fix
1386 sys_siglist declaration.
1387 * source.c (list_command): Fixed range computation to use
1389 * stack.c (backtrace_command): Do not allow command if target has
1390 no stack, print informative error message.
1391 * target.c (target_command): Do not write into command line
1392 because this fails if the target command is used in a user defined
1393 command. [This change was enhanced by gnu to support any-
1394 unique-prefix matching on target names.]
1395 * valops.c (value_struct_elt): Avoid infinite loop on an
1396 erroneous attempt to print the member of function (try p main.p).
1398 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1400 * expread.y (name_no_typename): Avoid reduce/reduce errors
1401 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1402 Since the GDB parser really doesn't use name_no_typename in a
1403 name-only context, the parser can't tell the diff between
1404 names and numbers here. Avoid allowing a name_no_typename
1405 to be a NAME_OR_*INT to resolve the conflict.
1407 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1409 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1411 * valprint.c (val_print_fields): bitfield printing didn't handle
1412 byte order. Indirect through a few more fns to cope.
1414 * values.c (modify_field): also cope with byte order.
1416 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1418 Cleanup for release 3.94.2:
1420 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1421 include files. Roll version to 3.94.2.
1423 * coffread.c (init_stringtab): Read length into unsigned char
1424 array before swapping; don't assume 32-bit longs.
1426 * target.c (target_info): Don't bother with get_sym_file, just use
1427 the symfile global variable.
1428 * symtab.h, symfile.c (get_sym_file): Delete it.
1430 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1431 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1432 (read_type): Replace one more error() with complain().
1434 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1436 * i960-tdep.c: Fix copyright attribution.
1438 * config.gdb: Quote all backquotes in doublequotes. You can
1439 quote me on that. BSD 4.4 shell found this one.
1441 * infptrace.c (throughout): The third argument to ptrace is an
1444 * infrun.c (wait_for_inferior): When program has terminated, we
1445 have to call target_terminal_ours before we pop that target off
1446 the stack (e.g. before a call to target_kill or
1447 target_mourn_inferior). This fixes problem where a program
1448 terminates, then GDB stops for (tty output) and you have to type
1449 "fg" to the shell to resume it. FIXME: This code for what to
1450 do after termination really should be in normal_stop instead.
1452 * gdbcore.h (read_memory_check): Change declaration; it changed
1455 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1456 4.4 prereleases, this avoids a bug in their sgtty compatability
1458 * remote.c: Use terminal.h rather than hand-rolling the same.
1460 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1461 * utils.c (strsave, strstr): Fix arg types.
1462 * valprint.c (val_print): lint
1464 MIPS symbol table support from Per Bothner:
1466 * symfile.c (symtab_fns): Remove initializer table that needs to
1467 be hacked for each new symbol file format supported.
1468 (add_symtab_fns): New function, chains symbol table
1469 handlers into the global list.
1470 (symfile_init): Search this list.
1471 * symfile.h: Add next pointer, declare add_symtab_fns.
1472 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1473 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1475 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1476 symbol *). Thus, we no longer need the hack to trash
1477 pst->filename. Good, since that hack confused code in symfile.c!
1479 (reorder_symtabs, destroy_all_symtabs): Removed static
1480 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1481 Instead, the latter now uses a temporary array (stack-allocated
1482 from an obstack, and then freed).
1484 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1485 haven't been set in the outermost stBlock of a procedure. This was
1486 a problem with f77 binaries on Ultrix 4.?.
1488 (new_symtab, new_symbol, new_type): Continue changing code to use
1489 obstacks more and otherwise conform to dbxread internal style.
1490 Made the free_code of symtabs be free_linetable (as in dbxread)
1491 instead of free_contents. This implies memory leaks when reading
1492 a new symbol table, until the conversion is finished. Did change
1493 (struct symbol) and (struct type) to be allocated on the
1494 symbol_obstack. Blocks and blockvectors are among the things
1497 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1498 tested much, but it solved one problem (reported by Meissner), and
1499 cleans up some other things. The problem happened when an
1500 included file contains actual code (functions) and not just
1501 definitions. The mips coff is a little inconvenient there, since
1502 it may cause a procedure to be mapped to the wrong psymtab.
1504 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1505 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1506 this will need work for the new core paradigm.
1508 Opcode patches from the net:
1510 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1511 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1512 missing altogether - they are added here. From Bruce Bauman.
1513 * mips-opcode.h: The low mask for C0 instructions was too small.
1514 From Garrett Lau. I modified the fix to check the entire 32-bit
1517 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1520 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1522 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1524 * dbxread.c (read_type): Pointer subtraction (value_sub in
1525 valarith.c) sometimes failed because the types of the
1526 pointers being subtracted were not identical.
1527 These differed because dbxread.c was allocating pointer types
1528 using dbx_alloc_type+smash_to_pointer_type instead of
1529 lookup_pointer_type. I failed to find a justification for the
1530 former, so I changed it to use the latter. Similarly, I
1531 replaced smash_to_function_type by lookup_function_type,
1532 and smash_to_reference_type by lookup_reference_type.
1534 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1535 _initialize_mipsread): corresponding changes.
1537 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1539 * source.c (mod_path): Do tilde_expand on each component of the path,
1540 rather than on the (list of) paths as a whole.
1541 (print_source_lines): Set first_line_listed in addition to
1542 current_source_symtab and current_source_line. If the source was
1543 not findable, after a "dir" command to fix the problem,
1544 a "list" would get the wrong lines.
1546 While I was there... (gnu):
1548 * dbxread.c (read_type): Change error to complaint.
1550 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1552 First attempt at detailed understanding of symbol table memory alloc.
1554 * dbxread.c (dbx_symfile_read): Free our string table if we
1555 aren't the mainline. Free the "info" struct since we're done with
1557 (init_psymbol_list): Free any previously allocated psymbol lists.
1558 (): FIXME: Should realloc-down the psymbol lists when done reading
1559 the main symbol file?
1561 * symmisc.c (free_symtab): Free fullname field too.
1563 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1564 (REGISTER_ADDR): Make result type unsigned int.
1566 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1567 define REGEX must also define REGEX1 (its dependency).
1569 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1571 * tconfig/i960: No longer works, points you at vxworks960 or
1574 * xgdb.c, XGDB-README: Remove file. Users can get the much
1576 * Makefile.dist: Remove all trace of xgdb.
1578 * breakpoint.c (breakpoint_1): Pass demangle arg to
1579 print_address_symbolic.
1580 (clear_breakpoints): Remove unused function.
1581 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1582 (breakpoint_re_set): Use catch_errors to do them all anyway.
1584 * gdb-int.texinfo (Host versus Target): Add section on what is
1585 a "host" feature versus what is a "target" feature.
1587 * infcmd.c (path_command, path_info): Handle the PATH variable
1588 (object search path) as conveniently as the source search path.
1589 * environ.c (set_in_environ): Set some vars in GDB's environment,
1590 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1591 * source.c (mod_path): New function, from guts of
1592 directory_command, modifies a path. Used by path_command.
1593 (directory_command): Call it.
1594 * defs.h (strsave): Declare.
1596 * utils.c (sevenbit_strings): Add new printing option.
1597 (printchar): Use it.
1598 (strsave): Provide this handy helper routine.
1599 (set_width_command): Rename set_screen_width_command.
1600 (_initialize_utils): "set screen-width" => "set width";
1601 "set screen-height" => "set height"; add sevenbit-strings.
1603 * infcmd.c (do_registers_info): Print floating point registers
1604 in raw hex as well as float format, regardless of whether it is
1605 a "virtual" convertible register.
1606 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1607 regs as a double, just in case it's being used that way.
1608 * values.c (unpack_long): Comment on array/function coercion.
1609 (unpack_double): Argument is in target byte order now. For
1610 integer arguments, just call unpack_long and float the result.
1611 * m68k-tdep.c: include defs.h for "const" handling.
1612 * remote-nindy.c: Use ieee-float stuff.
1613 (nindy_fetch_registers): Unpack double regs to host double, then
1615 (nindy_store_registers): Pack extendeds to host double, flip
1616 around by misusing unpack_double, send as target double.
1618 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1619 zero, as when stopped at the first instruction of a process.
1621 * blockframe.c: Fix filename in comment (param.h => tm.h).
1622 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1623 * tm-68k.h: Fix typos.
1625 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1627 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1629 * coredep.c (fetch_core_registers): Pass end-address of register
1630 section to register_addr as expected. Don't call supply_register
1631 if we'd just pass it garbage.
1633 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1635 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1637 * target.c (push_target, target_info): Cast enums to int for < or
1640 * stack.c (print_frame_info): Identify source file & line
1641 even if we can't print it.
1643 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1645 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1647 Clean up IEEE floating point support.
1649 * ieee-float.h: New file.
1650 * ieee-float.c: Write real routines to convert between host
1651 doubles and various target IEEE extendeds.
1652 * m68k-xdep.c: Eliminate assembler code for extended floats.
1653 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1654 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1655 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1656 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1657 double_to_ieee_extended.
1658 * i960-tdep.c: Define ext_format_i960.
1659 * m68k-tdep.c: Define ext_format_68881.
1660 * sparc-tdep.c: Define ext_format_sparc, though unused.
1661 * Makefile.dist (HFILES): Add ieee-float.h.
1662 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1665 Obsolete the "coffstrip" program in favor of using BFD's strip.
1667 * nindy-share/coffstrip.c: Remove file.
1668 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1669 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1670 * tconfig/nindy960: Remove reference to coffstrip.o.
1672 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1674 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1676 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1677 * dbxread.c: Remove static symfile_bfd.
1678 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1680 * inftarg.c (child_detach): Pop the child_ops vector if the
1681 detach is successful.
1682 * remote-nindy.c (nindy_create_inferior): Don't push a new
1683 nindy_ops since nindy uses the same one for execution and memory
1685 * core.c (core_ops): Use child_attach and child_create_inferior
1686 rather than default attach and create_inferior functions.
1688 Handle floating point registers in core files.
1690 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1691 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1692 This version untested since BFD doesn't yet support sun3 core
1694 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1695 conventions. Fix comments and style. This version has not
1696 been compiled yet, since we have no HP inhouse.
1697 * core.c (get_core_registers): Look for two sections, ".reg"
1698 and ".reg2", and pass both to fetch_core_registers sequentially.
1700 Revise directory path yet again.
1702 * source.c (forget_cached_source_info): Not static any more.
1703 (init_source_path): New default source path is "$cdir:$cwd".
1704 (dir_command): Handle variable arguments ($cdir, $cwd).
1705 (source_info): Print "Compilation directory" rather than
1706 "Originally compiled in" to remind people of $cdir.
1707 (openp): If the path contains $cwd, use current directory.
1708 (open_source_file): If compilation directory is known, replace
1709 first $cdir in path with the compilation directory.
1710 (print_source_lines): Even if we can't print the lines, set the
1711 current symtab and line for future commands like "info source" or
1712 "breakpoint". Also, error message now contains the file name,
1713 line number, and file access error message.
1714 (_initialize_source): Fix help text to describe changes.
1715 * main.c (cd_command): Forget cached source info when we chdir.
1716 * utils.c (strstr): Add simple implementation.

1720 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1721 Byte-swap COFF symbol tables if necessary when reading them in.
1722 Use complain() to replace error message in one spot. Needs
1723 corresponding change in bfd/coff-code.h to make some symbol
1724 swapping routines non-static.
1726 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1728 Merge changes from Eirik Fuller, for UTek.

1732 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1733 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1734 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,

1736 declarations of errno.
1738 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1740 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1741 <rpc/rpc.h> and <rpc/types.h>.
1743 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1745 * i960-tdep.c (examine_prologue): Add new argument limit,
1746 which stops the scan at the end of the prologue, or at the PC.
1747 This fixes a problem where it walks down into the code for the
1748 user's statements if that code looks like function prologues.
1749 Mark Fox and I have been bouncing this code back and forth, making
1750 small changes to it. Callers changed to match.
1752 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1754 Cleanup for gdb-3.94 release final:
1756 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1757 the .c files from vx-share and nindy-share, from the various
1758 macros, since they are not found via ALLDEPFILES.
1759 (SFILES): Add tm-i960.h.
1760 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1761 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1763 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1764 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

1768 * am29k-tdep.c: Add contribution line.
1769 (examine_prologue): Cache information about function prologues in
1770 the misc-function-vector to avoid lots of references over the
1771 serial line while examining instructions.
1773 * core.c (core_close): New function made from cleanup_core.
1775 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1776 remote-vx.c, remote.c, target.c, target.h,
1777 Update target_ops vector to add attach, close, and load entries.
1778 Use add_syms_addr_command, not add_file_addr_command, for
1779 add_file. Break out close routine from existing code.
1781 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1782 they are in an obstack.
1783 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1785 (define_symbol): Add symbol type parameter; change callers;
1786 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1787 it to influence the symbol class on the i960.
1788 (define_symbol): Swap LOC_CONST's into target byte order.
1790 * exec.c (exec_close): New function.
1791 (exec_file_command): Call it.
1793 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1794 Fix byte order of frame pointer.
1795 (read_var_value): Result of 0 if var's value can't be found,
1796 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1797 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1798 (locate_var_value): Use read_var_value and use its lazy address
1799 as the location of the var's value. Lint.
1801 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1804 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1805 obsolete Intel versions in favor of vxgdb versions.
1806 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1807 code dealing with byte order of values, which Intel did in host byte
1808 order rather than gdb-4's target byte order.
1809 (i960_frame_chain_valid): Move to nindy-tdep.c.
1810 (examine_prologue, skip_prologue, frame_find_saved_regs,
1811 frame_args_address, leafproc_return, saved_pc_after_call,
1812 pop_frame): Add vxgdb versions from Mark Fox.
1813 (examine_prologue, frame_struct_result_address): Add code
1814 to deal with the saved value of G13 (struct return address
1816 (frame_args_address): Modify Mark's version to prefer the
1817 saved value over the current value in the topmost frame.
1818 Cache result in the frame info to avoid performance hair in
1820 (print_fault): Add gdb960 code for printing faults.
1821 (_initialize_i960): Actually call check_host.
1823 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1824 add stub routines. FIXME, these currently just return zero!
1826 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1827 (attach_command): Call target_attach, not target_open, now.
1829 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1830 (child_attach): Rename from child_open.
1831 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1832 don't confuse it with a zero step_resume_break_address.
1834 * inftarg.c (child_detach): Eliminate inferior_pid test.
1835 (child_files_info): Clean up message a bit.
1836 (child_ops): Use child_attach, not child_open, to attach.
1838 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1839 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1840 findvar.c to here, since it depends on the contents of the
1841 shadow_contents of breakpoints, but keep if #if 0 since it is
1844 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1847 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1848 (ptype_command, display_command): Eliminate have_inferior_p and
1849 have_core_file_p in favor of target_has_stack or
1850 target_has_execution.
1851 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1852 code for actually finding the values of arguments, though we still
1853 keep track of the maximum stack offset for use in printing unnamed
1854 arguments. Handle missing FRAME_ARGS_ADDRESS.
1856 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1857 (struct nindy_regs): Define registers passed to/from nindy.
1858 (nindy_fetch_registers, nindy_store-registers): Translate between
1859 nindy and GDB formats for the registers.
1860 (dcache_init): Statically allocate the cache, since it was being
1861 allocated by a malloc that was never freed anyway.
1862 (nindy_create_inferior): Error, not core dump, if no exec file.
1863 (nindy_before_main_loop): Use target_load, not target_add_file.
1865 * remote-vx.c (net_load): Specify large timeout for load
1866 requests. Allow user to break out with INTERRUPT.
1867 (net_break): Remove useless code, clean up. Change callers.
1868 (parse-args, skip_white_space, find_white_space): Clean up arg
1869 parsing to cope with quoted strings.
1870 (net_wait, net_quit): Never call error, just return status.
1871 (vx_read_register, vx_write_register): Cleanup status checking.
1872 #ifdef the code based on which CPU we are using (960 or 68k),
1873 FIXME, this should be completely general but it isn't yet.
1874 (vx_xfer_memory, vx_resume): Cleanup status checking.
1875 (vx_run_files_info): Improve message.
1876 (vx_load_command): Renamed from vx_add_file_command. Allow load
1878 (net_ptrace): Remove unused routine.
1879 (vx_wait): Adopt code from vxgdb960 to cope with broken
1880 connections to target machine and prompt to disconnect. Remove
1881 debug printouts. Map some EVENT_'s to SIGnals.
1882 (add_symbol_stub, vx_open): Print names of object files we found,
1883 and "ok" if we read their symbols OK. Clarify output in general.
1884 (vx_attach, vx_detach, vx_kill): Add these commands.
1885 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1886 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1887 "info files" output, and create_inferior, since we already have
1890 * stack.c (frame_info): Replace Frame_unknown with 0.
1891 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1892 (return_command): Pop until the PC matches as well as the FP,
1893 so it works even if the FP is shared with another function,
1894 as in "frameless" or "leaf" procedures.
1896 * symfile.c (load_command): renamed from add_file_target_command.
1897 (add_syms_addr_command): renamed from add_file_addr_command.
1898 (add_syms_command): Stub to call target_add_syms.
1899 (_initialize_symfile): Change command names and descriptions,
1900 add-file => add-syms, and load from alias to its own command.
1902 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1903 maybe_kill_then_create_inferior): Default for attempts to start
1904 a process, if one is already running, is to ask about killing
1905 it and retry if yes.
1906 (upstack_create_inferior): #if-0 it, strata obsolete it.
1907 (push_target, unpush_target, pop_target): to_close() a target
1908 before unstacking it.
1909 (target_info): Renamed from target_files_info.
1910 (_initialize_targets): Rename "i files" as "i target", accessible
1913 * target.h: Improve comments about the target_ vectored routines.
1915 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
1916 Convert commenting style to standard GNU style.
1917 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
1918 (SKIP_PROLOGUE): No longer a no-op.
1919 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1920 (*_REGNUM): Sort register numbers.
1921 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1922 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1923 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1924 are now 10 byte extendeds, not 8 byte doubles.
1925 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1926 for nindy versus vxworks targets. FIXME, this should possibly go
1927 in the target vector.
1928 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1929 frame_saved_regs and arg pointer with each frame.
1930 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1931 (FRAME_ARGS_ADDRESS): Use cached result.
1932 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1933 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1934 (PRINT_RAMDON_SIGNAL): Call print_fault.
1935 (POP_FRAME): Now works.
1937 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1938 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1939 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1940 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1943 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1944 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1946 * valarith.c (value_subscripted_rvalue): Avoid handling
1947 floats and doubles specially; it gave alignment errors. Lint.
1949 * valops.c (value_of_variable, value_of_this): Error if unknown
1952 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1953 to avoid alignment problems.
1954 (value_print): Handle unknown value address.
1955 (cplus_val_print): Two args are ignored; remove them. Change caller.
1956 (val_print): Use unpack_long rather than pointer-deref.
1959 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1960 to avoid alignment problems.
1961 (value_being_returned): Error if return value unknown.
1962 (set_return_value): Add bogosity warning, FIXME. *
1964 * TODO: A woman's work is never done.
1966 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1967 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1968 Add ieee-float.o to OBS.
1969 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1970 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1971 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1973 Changes to generalize the VxWorks RPC protocol slightly, to handle
1974 i960 as well as 68000.
1976 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1977 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1978 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1979 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1980 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1981 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1982 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1983 so they will move in target byte order rather than network
1984 byte order (happens to be the same).
1986 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1988 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1990 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1993 Add contribution lines to various files, showing where they
1996 * breakpoint.c (break_insn, check_break_insn_size,
1997 read_memory_nobpt): Remove to mem-break.c.
1999 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
2002 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
2003 entry has bad register number. This change is not
2004 tested in this release, FIXME.
2006 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
2009 * value.h: Force value's contents field to be aligned to hold
2010 at least a double or a long long (if supported). This avoids
2011 doing bcopy's in and out of the contents field.
2013 (step_1): Avoid coredump under obscure circumstances when we
2016 * symtab.h (misc_info): Add field to misc function vector for
2017 any kind of cached information the target code desires. AMD
2018 29000 uses this to avoid repeating examine_function_prologue's.
2020 * coffread.c: Lint. Remove static symfile, read_section_header.
2021 core.c (have_core_file_p): Lint: remove.
2022 expprint.c (print_subexp): Lint.
2023 infptrace.c, valops.c, valprint.c: lint.
2025 Roll in changes from vxgdb-5.0.1:
2027 * symtab.h: Comment byte order of each address class. Add
2028 LOC_LOCAL_ARG for frame-relative args (960).
2029 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
2030 symtab.c, symmisc.c: ditto.
2032 * infrun.c (init_wait_for_inferior): Clear stop_signal.
2034 * remote.c (remote_resume): Error if resume with a signal.
2036 * symfile.c (prim_record_misc_function): Clear misc_info.
2037 (fill_in_vptr_fieldno): Check stub type of arg.
2039 * valops.c (value_cast): Avoid looking up names of types whose
2040 name we don't know, to prevent coredump. Sun CC produces typedef
2041 rtx and the name of *rtx is zero...
2043 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2045 Roll in changes from final AMD 29000 port (Tiemann).
2047 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
2048 for ../include/a.out.encap.h. This might not work now that BFD
2049 is separately compiled. Instead, BFD support for encap will have
2050 to translate machine type 29k into the right COFF_MAGIC.
2052 * infcmd.c: Remove references to inferior_pid that aren't used
2053 in actual ptrace calls; use target_has_execution, etc.
2054 (have_inferior_p): Remove function.
2055 (program_info): Print target info rather than "process number";
2056 avoid gratuitous messages unless from_tty.
2057 (run_stack_dummy, finish_command): Set proceed_to_finish.
2058 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
2059 main.c: Lint. Lose have_inferior_p().
2060 inferior.h (have_inferior_p): Remove, lint.
2061 (proceed_to_finish): Add flag to ask that all regs be saved
2062 by normal_stop, for the few commands that need it, speeding up
2063 serial I/O. Add comments to stop_registers.
2065 * remote-eb.c: Remove newline from breakpoint message we grep
2066 for. Never time out when running the user program.
2070 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2072 Roll in changes from vxgdb-5.0.1:
2074 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
2075 symbol in its raw form, we are processing an unlinked ".o" file.
2076 See if the target environment has assigned it an address, using
2077 target_lookup_symbol (VxWorks does), and enter it into the symtab
2080 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
2081 68k versions for a simpler version that assumes zero FP at bottom.
2082 Fixes bug of truncated stack reports.
2084 * target.h (target_lookup_symbol): Define this routine's args
2085 and result, finally.
2087 * target.c (nosymbol): Default routine for target_lookup_symbol.
2088 (target_default): Default lookup_symbol and call_function too.
2089 (files_info): Only print has_all_memory warning if a non-dummy
2092 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
2093 vx_convert_from_virtual): If target does not have floating point,
2094 zero register "values", and avoid doing cross-net conversions.
2095 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
2096 (vx_open): Rearrange code that attaches to target and reads
2097 symbols for all loaded modules, to work if some of the modules
2098 are not accessible. Add symbol_stub() and add_symbol_stub()
2099 as callbacks from catch_errors(). Allow connect attempt to be
2100 interrupted painlessly with ^C (FIXME, there are still some bugs
2101 if the interrupt happens during symbol reading.). Print
2102 final message with puts_filtered, since symbol messages are
2107 * main.c (catch_errors): Only print errstring if non-null.
2108 (command_loop): Avoid an ioctl per command to test ISATTY.
2110 * remote-vx.c (net_load): make static; avoid sophomoric msg.
2111 (vx_xfer_memory): Return correct result!
2112 (vx_files_info): Indicate whether target has float or not.
2113 (vx_lookup_symbol): Complain, not error, if target gone.
2114 (vx_open): Print "Connected" msg before disabling immediate-quit.
2115 [FIXME: lookup_symbol and vx_open changes need testing.]
2117 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
2118 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
2119 contributor lines and update copyrights to 1991.
2121 Changes from an attempted H-PUX host port:
2123 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
2124 defines PT_ATTACH and PT_DETACH but not PT_KILL.
2125 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
2126 * remote-vx.c: include <sys/time.h> for HPUX.
2127 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
2128 "core_file_command" routine to BFD regime. May not work yet.
2130 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
2132 * xgdb.c: Replace X10 version with some VJ version.
2133 (FIXME: Its copyright assignment is not on record.)
2134 * xgdb.c: Update include files to X11R4 (Xaw crud).
2135 (xgdb_display_source, create_text_widget): fix call to
2136 get_filename_and_charpos. Rewack source window stuff for X11R4
2137 (gleaned from include files, and "nm's" of binary libraries, since
2138 I had no doc available).
2139 (append_selection, append_selection_word): Disable with FIXME
2140 since R4 changed interface here.
2141 (create_buttons): Add back the old set of buttons.
2142 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
2144 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
2145 Roll VERSION to 3.94 (not yet final though).
2147 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2149 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
2150 obstack_int_grow, obstack_int_grow_fast): Eliminate
2151 cast on left of assignment, which gives MIPS cc fits and is
2154 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
2155 F_ALIAS. Use printf, not fprintf, when not passing a file
2157 (compare_opcodes): Check that identical instructions have
2158 identical opcodes, complain otherwise.
2160 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
2161 was reported by Roland McGrath.
2162 (unimp): Only match if exactly zero instruction. (Roland)
2163 (branches and traps): Generate all variations of these
2164 instructions with macros, based on a single call that defines
2165 each condition name and its binary representation.
2166 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
2168 * valprint.c (val_print_fields): Take, and use, format parameter.
2169 This means that "p/x struct" again prints the elements in the
2170 desired format. Changed callers.
2172 * stack.c (frame_info): Use filtered output, and indicate wrap
2173 points. Remove kludgy formatting designed to avoid line wrap.
2175 * utils.c (wrap_here): If the line is already full (because
2176 we had printed a long indent or long wrapped string), do an
2177 immediate newline-and-indent.
2179 * m68k-pinsn.c (print_insn_arg): Bugfix from
2180 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
2181 instruction is incorrectly disassembled as bkpt #8.
2183 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
2184 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
2185 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
2186 and then will dump core (sometimes). I traced it back to an
2187 uninitialized symfile_name in psymtab_to_symtab.
2188 (const_vol_complaint): Add quotes to message.
2189 (define_symbol): Only believe line number if gcc_compiled.
2190 Avoid allocating symbol if we will not return it.
2192 Add target strata support so that newly established targets go
2193 into their right place in the target stack (e.g. a new exec file
2194 doesn't wipe out the ability to access the running process).
2196 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2197 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2198 and initialize it properly in all the targets.
2200 * target.h: Document strata. Change return type of push_target.
2202 * target.c (nomemory): new function for dummy memory access.
2203 (tcomplain): Rename complain, now also used in symfile.c.
2204 (push_target): Push targets within strata. New return value shows
2205 whether new target is on top of stack or not. Always keep dummy
2207 (target_files_info): Ignore dummy target.
2209 * core.c (core_open): Warn user, and skip accessing file, if the
2210 core target is not the topmost target in the stack.
2211 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2214 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2215 target_ops, it doesn't belong there since we have no regs there.
2216 Change name of target from machine => memory to clarify.
2218 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2220 * Freeze version 3.93 for release.
2222 * Makefile.dist: Handle vx-share and nindy-share subdirs
2223 properly when building gdb.tar.Z.
2225 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2226 printed in various places, so I could change just one copy.
2228 * dbxread.c, coffread.c: Change references to bfd->iostream
2229 to cast to FILE *, now that BFD avoids needing types defined
2230 in other header files.
2232 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2234 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2235 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2236 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2237 (actually gcc -Wall).
2239 * dbxread.c: Remove first_global_sym, last_global_sym, since
2240 they are never referenced.
2242 * defs.h (baud_rate): Declare.
2243 main.c: Define it, and add the -b option to set it.
2245 * gdb-int.texinfo: Add text on how to define a new host or target
2246 architecture, prompted by Per Bothner's questions about MIPS
2249 * gdb.texinfo: Document "complaints". Change doc of -q since
2250 gdb no longer prints the copyright and blurb if you specify a file
2251 name to be debugged (just like Emacs). Add doc for Nindy-specific
2252 command line flags for specifying target serial port and such.
2253 Update copyright to 1991.
2255 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2256 has taken over for us the job of ripping up executable files. The
2257 crud caused Per Bothner's port to not compile.
2259 * infrun.c (normal_stop): Avoid printing "Program exited
2260 normally" if we are in batch mode. This allows a GDB which
2261 executes a program on a target system, to behave like a Unix
2262 command (input from stdin, output to stdout, no extraneous
2265 * main.c (main): Allow additional machine-dependent command line
2266 options to be specified with the ADDITIONAL_OPTIONS,
2267 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2268 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2269 processing to occur just before the main loop with
2270 BEFORE_MAIN_LOOP_HOOK.
2271 (main): If a "core file" argument is specified, and it is not a
2272 core file, try it as a process ID to attach.
2273 (symbol_completion_function): Attempt to cope with
2274 "show screen-" TAB, not very successfully. This needs more work,
2276 (batch_file): New function, returns whether we are reading
2277 commands from an interactive tty on stdin, or from somewhere else.
2278 Called by normal_stop since it doesn't get from_tty passed down
2279 to it like many commands do.
2281 * remote-nindy.c: Handle command line options for nindy
2283 (nindy_before_main_loop): Prompt user for tty name if they
2284 don't specify it before getting to the interactive command loop.
2286 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2287 and -r command line options. Also add hook before main loop
2288 to make it easy to specify a tty.
2290 * TODO: More things to do, one done.
2292 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2294 * dbxread.c: Make complaint() calls pass pointer, not struct.
2295 Add complaints about badly formatted C++ type information
2296 (const/volatile indicator, and parse errors resulting in
2297 error_type). Fix C++ virtual member fn comment.
2298 (read_struct_type): Avoid bumping pointer if we got a parse
2299 error; this prevents our walking beyond the end of a string.
2300 Terminate loop on null char as well as semicolon.
2301 (process_one_symbol): Fix the LBRAC fix so that it uses the
2302 last previous SLINE, FUN, or SO record's PC address. C++ debug
2303 symbols did not have SLINE records in a useful order compared
2304 to the LBRAC records.
2305 (define_symbol): Handle "catch" records.
2307 * symtab.c (check_stub_type): Added new complain
2308 `stub_noname_complain' and added a consistency check to
2309 keep the debugger from crashing when finishing from an
2310 exception frame. A real fix will be needed later.
2312 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2314 * infcmd.c (attach_command): Make global.
2316 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2317 but make them easy to comment out. Perhaps later they should
2318 be enabled by what CPU you configure for? FIXME.
2319 (VERSION): Roll to 3.93.
2320 (pinsn.o): Remove rule for obsolete file.
2321 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2323 Run down a problem that manifested by printing the wrong function
2324 name in stack traces of read_ofile_symtab. Turned out that the
2325 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2326 the LBRAC symbol with an address in the *data* segment, which
2327 blew our binary search through the blocks.
2329 * dbxread.c: Use the complain() facility consistently to bitch
2330 about problems in the symbol file we are reading.
2331 (finish_block): Add code to check the nesting of the blocks;
2332 complain and Procrust them to fit if wrong.
2333 (make_blockvector): Check the order of the blocks, complain
2334 [but don't cope] if wrong.
2335 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2336 symbols to be sure their PC value is greater than the last SLINE
2337 (line number) symbol we've seen, complaining and adopting the
2338 SLINE PC value if wrong.
2340 * symfile.h (struct complaint, complaint_root, complain,
2341 clear_complaints): Add.
2342 * symfile.c (complain, complaint_root, clear_complaints): Add
2343 facility to deal with non-fatal complaints and to regularize their
2345 (symbol_file_add): Clear complaint counters to allow new complaints.
2346 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2348 * dbxread.c (dbx_symfile_read): Remember the address and size
2349 of the string table for the main symbol file, so we won't read it
2351 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2352 to avoid reading the string table yet again. Lint.
2353 (throughout): Improve filtered output, including word wrap.
2354 (read_range_type): Improve Bothner's fix to handle other types too.
2356 * utils.c: Improve line wrap implementation. Handle unlimited
2357 width by making chars_per_line unsigned.
2358 (puts_filtered): New, easy, function.
2360 * defs.h (puts_filtered): add.
2362 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2363 call the identical sort_symtab_syms() in symfile.c instead.
2365 * expread.y: Suggest the `file' command rather than `symbol-file'.
2367 * command.h (enum var_types): Add zinteger for seroable
2369 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2370 nested if's into a switch.
2372 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2373 we did not stop because of a breakpoint (it must have been for
2374 some other reason, like a "stepi"), so don't print anything.
2376 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2377 doesn't include <sys/types.h>, old SunOS's require it for
2380 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2382 A test port of gdb-3.92.6 to the Sony NEWS.
2385 Don't normally link in remote- or vx stuff.
2386 Some of it doesn't compile, and it wastes space for 99% of the users.
2387 Remove reference to no-longer-used HAVE_VPRINTF.
2388 Fixed BFD_DEP typo to BFD_DIR.
2390 Fix cast in arg to bfd_h_getlong.
2391 Make char *prefix be const.
2392 Fix how certain range types are mapped into builtin unsigned int types.
2394 Remove 2 #includes. They cause errors (on Sony, at least),
2395 and aren't needed (they wern't in earlier versions).
2397 print_address_symbolic should never demangle labels
2398 (since it prints *assembler-level* labels).
2400 [This was superseded by the change to printcmd below.]
2403 Add some "volatile" return types to avoid warnings.
2404 If MISSING_VPRINTF add vprintf function and not just macro
2405 (since vprintf is used in printcmd.c).
2407 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2408 (The latter isn't grokked by some PCC-based compilers.)
2410 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2412 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2413 * nindy-share/coffstrip.c
2414 Added some forward declarations (otherwise, gcc complains
2415 about implicit extern redefined as static).
2417 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2419 Changes inspired by Per Bothner:
2420 * printcmd.c (print_address_symbolic): Take additional parameter
2421 specifying whether to demangle.
2422 (print_address): Pass in asm_demangle to control demangling.
2423 (print_address_demangle): New fn, takes explicit arg to control
2425 * utils.c: Add new vars demangle and asm_demangle, and let them
2427 (fputs_demangled): If !demangle, just print the argument.
2428 (fprint_symbol): If !demangle, just print raw symbol.
2429 * valprint.c (val_print): Call print_address_demangle rather than
2430 print_address, to cause demangling to depend on the global
2431 rather than assembler-level demangling setting.
2432 * WHATS.NEW, gdb.texinfo: Document.
2434 * main.c (show_command): Show all settings if no arg.
2435 (initialize_main): Make "info set" the same as naked "show".
2436 * command.c (cmd_show_list): Handle prefix commands in the
2437 list, and print the name of the setting as well as its English
2438 description and value.
2440 Allow gdb functions to specify where a line should wrap if it
2441 exceeds the size of a terminal line. Use it to make the output
2443 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2444 of the right size when screen width changes.
2445 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2446 (wrap_here): New fn, indicates a point in the output where we
2447 should wrap the line rather than just letting it overflow at a
2449 (fputs_filtered): Implement wrapping.
2450 (n_spaces): New fn, returns a pointer to N spaces.
2451 (print_spaces_filtered): Use n_spaces.
2452 * defs.h (n_spaces): Declare.
2453 * stack.c (print_frame_info): Wrap with 4-space indent after
2454 fn name and before filename and line number.
2455 * printcmd.c (print_frame_args): Wrap with 4-space indent
2456 before each argument name is printed.
2457 * valprint.c (value_print): Wrap with no indentation before
2459 (val_print_fields): Wrap with indentation relative to nesting
2460 level before each field name.
2461 (val_print): Wrap with nesting indentation before array elements.
2462 * command.c (do_setshow_command): Avoid extra newlines,
2463 wrap with 4-space indent around values printed, end with period.
2464 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2466 * breakpoint.c (breakpoint_1): Implement addressprint for
2467 "info breakpoints" display. Change file name and line number
2468 format to " at file:nnn" rather than " (file line nnn)".
2469 * gdb.texinfo: Document.
2472 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2474 Frozen for gdb-3.92.6 release.
2476 README, WHATS.NEW: Update for 3.92.6 release.
2478 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2479 coffread.o from configs since it is now built by default.
2480 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2481 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2482 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2483 from configs since it is now built by default.
2485 Makefile.dist: Update for release 3.92.6. Handle files that
2486 have been moved to ../include, ../getopt, or ../bfd. Add
2487 saber.suppress and tests directory. Add config.status to
2488 the release (it will say "none").
2490 coredep.c: Minor formatting fixes.
2492 These changes were made in early December but only checked in now:
2493 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2494 nindy-share/nindy.c: lint
2495 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2496 register values coming back from the target; we store values
2497 in target byte order everywhere.
2499 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2501 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2503 * valprint.c (cplus_val_print, val_print_fields): New functions,
2504 which print C++ objects. They conspire to avoid printing a
2505 virtual base class more than once, following all the twists and
2506 turns of C++ virtual base rules.
2507 (val_print): Call the above rather than do it by hand.
2509 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2510 symbol file, not for added files like shared libs. This really
2511 needs to be generalized to a timestamp per file.
2513 * core.c (cleanup_core): Avoid coredump if no core file.
2515 * config.gdb: Accept -host or -target in place of +host or
2518 * coffread.c (find_linenos): Avoid desupported BFD interface
2519 to line numbers. We still read them manually rather than using
2520 BFD's "generic" features.
2522 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2524 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2526 * Makefile.dist: Eliminate use of $< in explicit targets.
2528 * readline/Makefile: Use $< rather than $*.c, which does not
2529 include the VPATH in GNU Make.
2531 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2532 copies of tconfig/i960, added for global configuration
2533 compatability. All i960 versions can read both coff and b.out.
2535 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2536 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2539 * TODO: Think of more things to do.
2541 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2543 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2544 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2545 64-bit float conversion.
2547 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2548 equivalent to sun?os4 so global config works.
2550 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2552 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2554 * main.c: Only declare linesize once; declare pagesize not at
2555 all, since it is never used.
2556 (main): Clear newly allocated line before it is used.
2558 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2560 Further stabilization for the Intel 960.
2562 * Makefile.dist: Parameterize the location of the "include"
2563 and "bfd" directories, as well as "getopt". Add symfile.c.
2564 Link in both dbxread and coffread. Fix up "make depend" to
2565 rewack the locations of include, bfd, and getopt in its output.
2567 * README: Document moving include files, improve some of
2570 * coffread.c: Move common code out to symfile.c. Change
2571 symbol_file_command style interface to use new *_symfile_init
2572 and *_symfile_read interface under BFD. Use BFD internal
2573 info to locate line table, symbols, etc.
2575 * core.c (core_fetch_registers): Rename to get_core_registers
2576 to avoid confusion with fetch_core_registers.
2577 (register_addr): Move to coredep.c, which is already machine
2578 dependent. This leaves core.c pretty clean of dependencies.
2580 * coredep.c (register_addr): Accept this routine from core.c.
2582 * dbxread.c: Move common code (with coffread.c, etc) into new
2583 symfile.c. Each psymtab now contains a pointer to the
2584 format-dependent function that knows how to read it in. Make
2586 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2587 (process_one_symbol): Add code to complain about a "compiler bug
2588 we muzzle here", if we actually see it.
2590 * eval.c (evaluate_subexp): Insert missing "break" statements
2591 in code that determines whether a variable is an lvalue in
2592 memory, register, or whatever. I detected this via a compiler
2593 bug in which it *almost* mashed out the whole switch statement.
2595 * gdb-int.texinfo: Add minor sections on configuring gdb for
2596 release, and about the README file.
2598 * infcmd.c (registers_info): Fix formatting somewhat. Still
2599 not as pretty as before, but it handles byte swapping.
2601 * remote-nindy.c: If data cache routines are interrupted while
2602 waiting for the remote end, be sure that any uninitialized cache
2603 blocks are on the free list, not on the valid list!
2605 * symfile.h: Flesh out this header file with all the various
2606 routines and variables that have been merged in from dbxread.c
2607 coffread.c, and symtab.c to symfile.c.
2609 * symfile.c: New file, containing code common to dbxread.c,
2610 coffread.c, and some code from symtab.c. All generic code for
2611 reading symbol files should be in here now.
2612 (unrecord_misc_function): Remove unused function.
2614 * symtab.h: Remove file-reading things to symfile.h.
2616 * symtab.c: Remove file-reading things to symfile.c.
2618 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2619 to decode i960 fault types.
2621 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2622 target.c: Change type of the "resume" function from int to void,
2623 since its result was never used.
2625 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2627 * main.c: Replace "stupid" with "caution"; you now "set caution
2630 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2632 * infcmd.c (do_registers_info): Call val_print to deal with the
2633 byte order of the registers being printed. FIXME, this makes
2634 the formatting of the output uglier.
2636 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2637 defined, call it for signals the debugger doesn't itself use.
2638 The i960 uses this for more detailed fault information.
2640 * remote.c (remote_open): If arg is null, print help rather than
2643 * sparc-xdep.c (register_valid): Avoid declaring size, since
2644 various modules will think of various sizes depending on the
2645 architecture of their tm-file. FIXME, we need protection against
2646 actually entering one of those modules, which would clobber
2647 storage if not for the target architecture compiled into gdb.
2649 * stack.c (up_command, down_command): Always print the frame
2651 (up_silently_command, down_silently_command): New commands
2654 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2656 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2657 more parameters than it used to.
2659 * findvar.c (registers): Increase slop to 256 bytes, which should
2660 protect us against even most RISC machines with large register
2662 (locate_var_value): Move declaration inside related ifdef.
2664 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2665 throughout, to avoid throwing away buffered input from the board.
2666 (nindy_wait): Supply_register takes addr_of_value, not value.
2667 (i960_print_fault): Renamed from i80960_fault.
2668 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2669 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2671 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2672 we can set the PC in the call to proceed(). Unpush nindy_ops
2673 before pushing it on top, to avoid message to user. Eliminate
2674 commentary from Unix machines that just misleads here.
2675 (reset_command): Fix error message to suggest target command.
2677 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2679 Release 3.92.5 as frozen.
2681 Stabilize the merged release...with help from lint, Saber C,
2684 Everywhere: Add include files needed to declare return types
2685 of functions called.
2687 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2689 * breakpoint.h: Add undeclared breakpoint functions, and some
2690 functions for display handling since I couldn't think of a better
2693 * breakpoint.c (insert_breakpoints): Make code for disabling
2694 shared library bkpts more likely to work. It's used when we
2695 rerun a program and stop before the shared library has been
2697 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2698 cast from pointer, so it squeezes through catch_errors.
2699 (bpstat_stop_status): Fix logic broken some time ago. We now
2700 always create a bpstat if the stop address matches a breakpoint,
2701 even if we don't stop there -- just like the old code used to do
2702 before I got my fingers into it (sigh).
2703 (breakpoint_1): Print "ignore count" after "stop only if"
2704 condition, since that's how it actually works.
2705 (mention): Handle watchpoints as well as breakpoints.
2706 (watch_command): use set_raw_breakpoint and mention to do most
2707 of the work (and initialize all the fields!). Only pass one
2708 arg to parse_c_expression, since that's all it takes.
2710 * command.c (not_just_help_class_command): Rename arg to args
2711 since we ignore "unused argument" warnings on vars named "args".
2712 inflow.c (child_terminal_info): ditto.
2713 infptrace.c (kill_inferior): ditto
2714 main.c (catch_errors, version_info, quit_command, pwd_command,
2715 source_command, dump_me_command, editing_info,
2716 set_history_size_command, set_history, show_history,
2718 stack.c (locals_info): ditto
2719 target.c (target_files_info): ditto
2720 valprint.c (set_input_radix, set_output_radix): ditto
2722 * core.c: Remove old variables for handling core and exec file
2723 sections (data_start, data_end, stack_start, stack_end,
2724 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2725 text_end, exec_data_start, exec_data_end, text_offset,
2726 exec_data_offset, data_offset, stack_offset). They're
2727 superseded the more general build_section_table and
2729 (get_exec_file): Mention the `file' command.
2730 (read_memory_check): Rename to memory_error, and only call it
2731 in the case of an actual error.
2732 (read_memory, write_memory): call memory_error.
2733 (core_fetch_registers): Register section name is ".reg".
2735 coredep.c: Remove a bunch of crud now that all this file does
2736 is pull the registers out of a core file.
2737 (fetch_core_registers): Rewrite to actually work, I hope.
2739 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2740 Replace index() with strchr(). Remove all the pre-BFD macro
2741 definitions for accessing the symbol file.
2742 (struct dbx_symfile_info): Encapsulate the information that
2743 dbx_symfile_init needs to pass to dbx_symfile_read in this
2746 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2747 dbx_symfile_discard): Rearrange symbol file reading to divide
2748 the format-specific part from the format-independent part,
2749 leaving the format-independent part such as file name expansion
2750 and opening in symtab.c. This replaces
2751 partial_symbol_file_open and partial_symbol_file_read.
2752 Symbol_file_read, add_file, add_file_target_command,
2753 add_file_addr_command move to symtab.c. Pass an explicit
2754 "mainline" flag for when reading the main symbol table, rather
2755 than relying on the offset address to be zero or nonzero.
2757 (dbx_symfile_read): Don't allow void *'s to be printed as
2759 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2760 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2761 macro" debug version really work.
2762 (read_dbx_symtab): Remove unref'd parameter inclink.
2763 Avoid swapping N_SLINE symbols, for speed.
2764 Merge N_TEXT!N_EXT case with the other external symbol
2765 definitions' case. Add comments.
2766 (start_psymtab): Allocate the symfile name in the psymtab on
2767 the psymbol_obstack, rather than using the caller's storage.
2768 (end_psymtab): Only allocate a dependencies list if there are
2770 (psymtab_to_symtab_2): Use BFD when reopening file to read
2771 its symbols for real.
2772 (read_struct_type): Add FIXME comments where it needs work
2774 (read_huge_number): Add FIXME about overflows.
2775 (read_range_type): Add FIXME about comparing a long to 1<<32.
2777 * coffread.c: Minor changes to move things closer to the new
2778 regime with symtab.c and dbxread.c Major work is still needed
2781 * exec.c (exec_file_command): Remove old variables (see core.c
2783 (xfer_memory): If memory transfer is right at the end of a
2784 section, don't lose.
2786 * findvar.c (get_saved_register): If value is in a real
2787 register, LVAL is lval_register, not lval_memory.
2789 frame.h: Declare print_sel_frame and record_selected_frame.
2791 gdb-int.texinfo: New file, for GDB internals documentation.
2792 Very simple, unformatted doc of cleanups is there for now.
2794 gdbcore.h: Remove obsolete variables that described a.out
2795 section addresses and offsets. (See core.c above.)
2796 Declare fetch_core_registers and registers_fetched.
2798 getopt.c: Declare char *alloca(); even on SPARC.
2800 infcmd.c (run_command): Call target_kill rather than
2802 (step_command, next_command, stepi_command, nexti_command):
2803 Declare from_tty parameter even though we don't use it.
2804 (run_stack_dummy): argument BUFFER is a char array, not
2805 a pointer to REGISTER_TYPE.
2806 (finish_command): using_struct_return needed a value *,
2807 not a struct symbol *.
2809 * infptrace.c (child_xfer_memory): To avoid dependency on
2810 where sections are in memory, try PT_WRITE_D and if that fails,
2811 try PT_WRITE_I. Most Unixes don't care which you use.
2813 * infrun.c (step_resume_break_shadow): Change to array to
2814 match other breakpoint shadow storage.
2815 (clear_proceed_status): Pass address of bpstat to
2816 bpstat_clear, not the bpstat itself.
2817 (child_create_inferior): FIXME comment about if the child
2819 (start_inferior): Remove old function.
2820 (child_open): Use target_kill rather than kill_inferior.
2821 (wait_for_inferior): Ditto.
2822 (insert_step_breakpoint, remote_step_breakpoint): Use
2823 new step_resume_break_shadow.
2825 * inftarg.c (child_wait): If all child processes die,
2826 pretend that the one being waited for exited with signal 42.
2828 * main.c (command_line_input): When scanning for comments,
2829 don't coredump on unclosed quotes.
2830 (quit_command): Use target_kill rther than kill_inferior.
2831 (_initialize_main): Rename class_user from "user" to
2834 * printcmd.c (print_command_1): Initialize "fmt" if no format
2835 is specified by the user.
2836 (print_frame_args): Only add to args_printed if we are
2837 actually fetching args from the stack (avoiding undefined
2839 (_initialize_printcmd): Remove bogus \{ from string.
2841 * remote-eb.c (eb_open): Avoid coredump on no argument.
2843 * remote-nindy.c: Bring out of Intel environment into new
2844 target environment. Remove all conditional compilation on
2845 I80960. Massive hacking throughout.
2846 (nindy_xfer_inferior_memory): New routine stolen from
2848 (nindy_create_inferior): New routine pieced together, probably
2849 not quite working yet.
2850 (nindy_ops): New target_ops struct for nindy.
2852 * remote-vx.c: Use write_memory rather than target_write_memory
2853 to get error checking.
2854 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2856 (vx_create_inferior): Use target_terminal_ours...
2858 * signame.c (_initialize_signame): Always initialize, since
2859 we need the table for things other than psignal.
2861 * solib.c (solib_add): Use symbol_file_add, not add_file.
2862 (solib_address): Return boolean result rather than struct
2863 pointer which nobody else knows the type of.
2865 * sparc-tdep.c, valops.c: Use write_memory rather than
2866 target_write_memory, to get error checking.
2868 * stack.c (locals_info, catch_info, args_info,
2869 get_selected_block, frame_command, up_command): Use
2870 target_has_stack, rather than have_inferior_p or
2873 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2875 * symfile.h: New file, defining the interface between the
2876 generic and object-file-specific symbol reading code.
2878 * symtab.c: Move generic symbol-reading interface to symtab.c,
2879 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2880 table to map BFD targets to symbol-reading modules in GDB.
2881 Change index to strchr.
2882 (lookup_struct_elt_type): Use error() rather than hand-made
2883 simulations thereof.
2884 (lookup_partial_symbol): Speedup slightly when length == 0.
2885 (symbol_file_add): New function.
2886 (symbol_file_command): Call it.
2887 (symfile_open, symfile_init): New function.
2888 (add_file_target_command, add_file_addr_command): moved from
2891 * target.c (target_command): use target_kill.
2893 * target.h (target_files_info): Don't declare, never called
2896 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2897 files to determine stack end address.
2899 * valarith.c (value_x_binop, value_x_unop): Change error message
2900 to be more useful. Pass proper argument to value_struct_elt.
2902 * valops.c (value_assign): FIXME comment that long long
2903 bitfields will break here.
2905 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2906 Update `make saber_gdb' to work better.
2908 * TODO: A woman's work is never done.
2910 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2911 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2912 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2913 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2914 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2915 valops.c, valprint.c, exec.c: Lint.
2918 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2920 Continuing Intel 960 port merge of GDB.
2922 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2923 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2924 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2925 Wack over "make depend" so it handles files in subdirectories
2926 vx-share, nindy-share, bfd, and in the current directory.
2928 * blockframe.c (get_prev_frame_info): Remove fatal error
2929 if stack not defined.
2931 * core.c (core_open, core_detach): New functions that handle
2932 the old "core-file" command as "target core" and "detach" instead.
2933 (core_file_command): Call them.
2934 (core_xfer_memory): Use common routine xfer_memory.
2936 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2937 dbxread now uses bfd for everything but symbol reading itself.
2938 BFD internals are used to drag out the relevant file offsets.
2939 (partial_symbol_file_open): Change args all around for BFD.
2941 * symtab.c: Rename "value" to "val" everywhere, so we can
2943 (symbol_file_command): New command, moved from dbxread.c
2944 and coffread.c. It uses BFD to read the file, then vectors
2945 based on its type, to dbx or coff symbol readers.
2946 * symtab.h: Extern a few vars for symbol_file_command.
2948 * target.h: Breakpoint takes a char * save area, not a char **.
2950 * valprint.c (val_print): When unpacking bitfields, offset
2951 the address in gdb of the value, if it is declared with a shorter
2952 type. Remove the last "runtime kludge test" of host byte order.
2954 * utils.c: Remove old my_bfd_read routine.
2956 * stack.c (frame_info): Use target_has_stack. Print program counter
2957 register's actual name rather than "pc", since it's called the
2958 "ip" (instruction pointer) on the i960 (sigh).
2960 * target.c (target_command): Add command for selecting a target
2961 type and calling its open routine. This is used for initiating
2962 communication with a particular target, in a generic way.
2964 * tm-i960.h: Update for modern gdb. Remove semicolons from
2965 various macros. Handle reading struct return convention, and
2966 error-out attempts to return structs with the "return" command.
2967 Be sure gdb doesn't think we know how to call functions in the
2970 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2971 to i960_xxx in lower case.
2972 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2973 not being defined yet.
2975 * remote.c (remote_open): Call start_remote to initialize
2976 wait_for_inferior during open.
2977 (remote_xfer_inferior_memory): Return length written rather
2980 * remote-vx.c (target_command -> vx_open): Use new generic
2982 * remote-eb.c, inftarg.c, exec.c: ditto.
2984 * infrun.c: Fix comments.
2985 (attach_program -> child_open): Use new generic target command.
2986 (wait_for_inferior): Clear saved register values before target_wait,
2987 so target_wait can set some of them if convenient.
2989 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2990 Return success indicator, not void.
2991 (child_xfer_memory): Avoid fetching initial word if we'll
2992 overwrite it anyway.
2994 * infcmd.c (attach_command): Use new generic target open routine.
2995 (_initialize_infcmd): Update doc on attach and detach commands.
2996 (do_registers_info): Merge in a byte-order problem as a FIXME
2999 * findvar.c (find_saved_register): Avoid problem in current frame.
3000 (read_relative_register): Ditto.
3001 (write_register): Convert byte order on the way out.
3003 * exec.c (file_command): Add.
3004 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
3005 (xfer_memory): Common function between core_xfer_memory and
3007 (exec_xfer_memory): Use it.
3009 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
3011 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
3012 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
3013 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
3015 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
3017 Merge Intel 960 port of gdb, continuing...
3019 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
3020 symbol_file_command): Pass from_tty arg to hush 'em up.
3022 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
3023 Add magic numbers for 960 COFF format.
3025 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
3027 Merge Intel 960 port of gdb, from Intel "1.2" release.

3046 "-se" switches as soon as they are encountered on the invocation line.
3048 Fri Apr 20 13:47:15 PDT 1990
3051 Thu Apr 19 09:54:28 PDT 1990
3052 Add 'reset' command.
3054 Wed Apr 18 09:48:07 PDT 1990
3055 After opening remote tty, wait for 1 second to go by without input
3056 from it before trying to talk to NINDY (fixes problems with the
3057 Heurikon HK80/V960E).
3059 Mon Apr 4 16:33:05 PDT 1990
3060 Some output was not being suppressed in 'batch' mode.
3062 Thu Mar 22 15:31:11 PST 1990
3063 Ask user if old symbol table should be deleted when new file is
3066 Allow user to run a program downloaded before gdb960 was brought up.
3068 Correct "exec-file" help message for i80960 context.

3078 code loaded at addresses higher than 0x7fffffff.
3080 Wed Jan 10 12:43:22 PST 1990
3081 Open remote tty for exclusive use.
3083 Fri Jan 5 12:14:42 PST 1990

3085 opcode for sysctl is 0x659
3087 Mon Oct 23 12:03:04 PDT 1989
3088 Use G960BASE and G960BIN environment variables to find 'sx' utility.
3090 Mon Oct 16 14:15:09 PDT 1989
3091 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
3093 Mon Oct 2 15:56:31 PDT 1989
3095 Added 960CA disassembly support.
3097 To simplify maintenance:
3098 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
3100 - eliminated opcode.h: incorporates tables into i960-pinsn.c
3101 - moved 960-specific routines from i960-pinsn.c to i960-md.c
3102 - made disassembly interface identical to that in gdmp960.
3106 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
3108 * target.h: Allow targets to stack. Add target_has_memory,
3109 _registers, etc. Restructure memory access and "info files"
3110 to walk the target stack.
3111 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
3112 target.c: Change tables to match target.h.
3113 * inflow.c (child_mourn_inferior): pop child_ops.
3114 (generic_mourn_inferior): Use new has_stack flag.
3115 * infptrace.c (child_xfer_memory): New memory regime.
3116 * inftarg.c (child_files_info): New "info files" regime.
3117 * remote-eb.c: New memory regime, new info files.
3118 * remote-vx.c: New memory regime, new info files. Now use
3119 separate targets for VxWorks attachment to machine, and
3120 actually running a process under VxWorks, since one has
3121 stack & execution & regs and the other doesn't.
3122 * remote.c: New memory regime, new info files.
3123 * sparc-xdep.c (fetch_core-registers): New memory regime.
3124 * target.c: New routines and support for stacked targets,
3125 new memory regime, new info files regime.
3128 Generalize section handling for an arbitrary number of sections,
3129 including use of the new BFD (binary file) library.
3130 * gdbcore.h: Add struct section_table.
3131 * exec.c (build_section_table): Iterate all sections and
3132 record what gdb needs to know about them.
3133 (exec_command): Use it.
3134 (exec_xfer_memory): Use the table.
3135 (exec_files_info): Print the table.
3136 * core.c (core_file_command, core_xfer_memory, core_files_info):
3138 * source.c (find_source_lines): Use bfd_get_mtime.
3139 * dbxread.c: Quick changes to make it compile with new BFD.
3140 * utils.c (error): Avoid using bfd_error in generic routines.
3142 * core.c (core_fetch_registers): Get from the ".regs" section of
3144 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
3146 * inferior.h (attach_flag): Export.
3147 * infcmd.c (run_command): use new target_create_inferior.
3148 * infrun.c (child_create_inferior): Don't return result.
3149 * Makefile.dist (VERSION): 3.91.4.
3151 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
3153 * breakpoint.c (bpstat_num): Handle breakpoints which have
3154 since been deleted, such as temporary breakpoints.
3155 infcmd.c (program_info): ditto.
3157 * core.c (core_file_command): Display the frame where the core
3162 * remote-vx.c (target_command): Merge in target command from
3163 targ-vx.c. A few other cleanups.
3165 * TODO, Projects: Lots more stuff to do...
3167 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
3169 Massive changes to wall off the remote-debugging interface
3170 behind a function vector. The port to handle VxWorks targets
3171 is also part of this.
3173 All files: Replace references to renamed functions,
3174 remove references to remote_debugging, remove references to
3175 have_include_file, have_core_file in favor of target_has_stack,
3176 target_has_memory, etc.
3178 * Modularize the breakpoint interface.
3179 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
3180 a breakpoint instruction.
3181 breakpoint.c: struct breakpoint's shadow_contents now sized as
3183 (insert_breakpoints): Vector to target to install breakpoints.
3184 (remove_breakpoints): Vector to target here too.
3185 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
3186 sparc-tdep.c (single_step): Use new breakpoint interface for
3187 the single-step breakpoints.
3188 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
3189 New file, contains routines to insert and remove breakpoints by
3190 reading out the old contents and later replacing them. This is
3191 how ptrace breakpoints work, and many remote systems as well.
3193 * tm-vxworks68.h: New config file, overrides a few things for
3194 Wind River's preferences.
3196 * target.h: New file, for transfer vector used to talk to the
3197 inferior (child, attached, core, exec, remote, etc). All accesses
3198 to the thing being debugged should come through these vectors.
3199 target.c: New file, routines to handle transfer vector.
3200 (various files): Add transfer vectors XXX_ops for the various
3201 targets and pseudo-targets (core files, etc) we support.
3203 * breakpoint.c (bpstat_stop_status): Further explorations of
3204 watchpoints and why things don't work all the time.
3205 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3207 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3208 the local gdbinit if it doesn't already have it.
3210 * core.c (core_ops): add and install.
3211 Allow core debugging without exec file.
3213 * dbxread.c (free_and_init_header_files): Merge two fns.
3214 (end_symtab): Free named symbol table when a new version comes in.
3215 (read_dbx_symtab): Relocate all kinds of symbols with base
3216 address. First step toward handling different text, data, bss
3218 (add_file_addr_command): Renamed add_file_command.
3219 (add_file_command): Vector to remote handler.
3220 Add "load" as an alias for "add-file" command.
3222 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3223 non-returning functions.
3225 * exec.c: Add exec_ops, and push it as a target when an exec
3228 * infcmd.c (run_command): Pass executable file name and arg list
3229 separately when starting an inferior. Permit "run" when no exec
3230 file is specified, for VxWorks.
3231 (detach_command): Move to child_detach in inftarg.c.
3233 * inftarg.c: New file. Unix-child-specific routines, and the
3234 child_ops structure.
3236 * inferior.h (registers): Export "registers" as the way for
3237 target dependent register handlers to find gdb's local copy of
3238 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3239 since it is now used by places that want wait_for_inferior to
3240 handle the grunge but want to see every trap from the inferior.
3242 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3243 Eliminate remote_debugging hooks in terminal handling.
3245 * infrun.c: Replace start_inferior with child_create_inferior.
3246 Move all the hair of Unix shells and ptrace idiosyncracies into
3247 child_create_inferior, so remote handlers don't have to deal.
3248 Remove running_in_shell. Rename stop_after_attach to
3249 stop_soon_quietly, and use it in a few other places where we want
3250 to just call wait_for_inferior and get control back on the first
3251 trap. trap_expected now never takes a value > 1.
3252 (init_wait_for_inferior): Initialize static vars when a new
3255 main.c (gdbinit): Add new hook for .gdbinit file name, let
3256 it be overridden by config files as GDBINIT_FILENAME.
3257 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3258 Both of these are used for VxWorks gdb.
3260 mcheck.c: rename include file "gmalloc.c" to avoid problems
3261 with system include file "malloc.c".
3263 param-no-tm.h: New include file, same as param.h but does not
3264 include the default "tm.h" file. This is used in files where
3265 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3267 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3269 remote-vx.c: New file, VxWorks remote debugging support. Uses
3270 RPC routines that are shared with the target system, in directory
3273 remote.c: Vectorize remote interface.
3275 source.c: Globalize source_path, and make an alias "l" for "list"
3276 since we now have the "load" command.
3278 sparc-xdep.c: Use new param-no-tm.h.
3280 symmisc.c (free_named_symtab): Add new function from Wind River.
3281 However, ifdef it out for now while we think about what it should
3284 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3286 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3287 non-Unix-children handle this with their own code in the target
3290 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3291 source and target lists. Add vx-share to default list of include
3292 directories. Add new files to src and target lists: mem-break,
3293 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3294 ${srcdir} versions of munch and createtags are used.
3296 * valops.c (find_function_addr): Split out of call_function.
3297 (call_function_by_hand): Rename call_function; this function
3298 calls functions in the target by laboriously patching the target
3299 word-by-word with the right stack, args, regs, etc.
3302 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3304 Handle AMD 29000 a bit better.
3306 * remote-eb.c (readchar): Mask received char log to make it readable.
3307 (remote_start): Pass arguments down to executing program.
3308 Make startaddr unsigned.
3309 infrun.c (start_inferior): Accept args, pass them to
3311 infcmd.c (run_command): Pass args down to start_inferior.
3313 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3314 the target object file format.
3315 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3317 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3318 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3320 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3322 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3323 * TODO: We did a few things, we have more to do though.

3331 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3332 (sparc_push_dummy_frame): Simplify and fix what we push.
3333 (sparc_pop_frame): Slightly more hair here, deciding whether
3334 we are restoring a saved PC or returning to a return address in %i7.
3335 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3337 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3338 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3339 * obstack.h (chunkfun): ditto.
3340 * defs.h (xmalloc, xrealloc): ditto
3342 * utils.c (quit): Grab the terminal from the child if necessary.
3344 * inflow.c (term_status_command): Rename to term_info, change
3347 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3348 (is_delayed_branch): Speed up.
3349 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3350 Still missing some float ops, and needs testing.
3352 * Support for input and output radixes other than base 10
3353 * defs.h (input_radix, output_radix): Declare.
3354 * expread.y (yyparse, parse_number): Handle changes of input
3355 radix, and ambiguous names-or-numbers in radixes >10.
3356 * printcmd.c (print_scalar_formatted): Print formatted hex
3357 numbers in varying column widths.
3358 * valprint.c (val_print): Use output_format to print scalar ints.
3359 (set_input_radix, set_output_radix, set_radix): Create.
3360 (set_output_radix): Set output_format from output_radix.
3361 (_initialize_valprint): add `set radix' but leave the others off.
3363 * main.c (execute_command): Let stupid questions be turned off.
3364 (_initialize_main): Handle "set stupidity", etc.
3366 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3367 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3369 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3371 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3372 bfd stuff is still screwed up, but with some manual work, it
3375 * breakpoint.c (bpstat_do_actions): Start over if a command
3376 proceeds the inferior, since the inferior will have stopped and
3377 will need to have its new stop-actions taken care of.
3379 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3380 compiler fits, simplify it.
3382 * gdb.texinfo (directory command): Doc new dir command.
3383 source.c (directory_command): "dir" now puts things on the front
3384 of the path, moves dups up front, and handles multiple names
3385 on the command line, inserting each one in order. It also
3386 blows away cached line and full_filename info.
3388 * stack.c (backtrace_command): Skip "more stack frames follow"
3391 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3392 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3393 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3394 The only odd one was Gould NP1, which had defined vprintf to
3397 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3398 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3399 variable, inspect_it.
3400 valprint.c (print_string, val_print): Use the global inspect_it
3401 to indicate whether to print in Epoch style or normal style.
3403 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3405 * printcmd.c (call_command): add an alias for the "print" command
3406 which runs expressions and doesn't print the result if void.
3407 (print_command_1): implement it.
3409 * command.c: Remove #if 0'd code. Initialize all the fields
3410 in add_cmd (). Rename do_nothing_command to
3411 not_just_help_class_command, and make it externally visible.
3412 command.h: add user_commands to struct.
3413 * main.c (define_command): Don't overload c->function with a char
3414 string as well as a function pointer.
3416 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3417 calling convention of value_struct_elt () that got dropped in
3420 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3421 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3423 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3425 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3426 until a good time (e.g. when we are about to run the child),
3427 saving ptrace calls.
3428 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3429 * tm-sparc.h: define DO_DEFERRED_STORES.
3431 * sparc-xdep.c (store_inferior_registers): when storing float
3432 registers, don't store stack regs too. When storing the SP,
3433 however, DO store the stack regs too. This fixes a bug in which
3434 the dummy frame is not recognized when a call_function finishes,
3435 because its frame pointer (in the stack regs) was never
3437 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3438 even though we don't know how to read them from an inferior.
3439 valops.c (call_function): Comment about storing SP.
3441 * infrun.c (save_inferior_status): Save away the original bpstat
3442 chain so it can be restored later. Install the copied version for
3443 use by whoever saved the status. It will be blow away by
3444 restore_inferior_status, and the original chain restored. This is
3445 important for people who have pointers into the original.
3447 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3448 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3449 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3452 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3454 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3455 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3456 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3458 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3460 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3461 Store the baseclasses in a type struct starting from array element
3462 0 rather than from the unusual array element 1.
3464 dbxread.c: the above.
3465 (virtual_context): Add
3466 Read new debug information about which virtual function table
3467 a virtual function is from, and store it in fn_field.fcontext.
3469 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3470 TYPE_FN_FIELD_STATIC_P.
3472 symtab.c: the above.
3473 valops.c: the above. Handle pointer casts of object *'s.
3474 (search_struct_method): Add.
3475 (value_struct_elt): First arg is now a pointer to a value, and is
3478 valprint.c: the above.
3479 values.c (value_virtual_fn_field): Add type arg. Handle
3480 offsetting to the proper object when calling virtual fns.
3482 (baseclass_addr): Add valuep arg.
3484 * README: Document the current state of BFD config (missing).
3485 * TODO, ChangeLog, Makefile.dist: Roll version.
3486 * WHATS.NEW: Add summary of changes since 3.5.
3488 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3490 * dbxread.c (read_struct_type): Clear bit vectors whenever
3492 symtab.c (B_CLRALL): define.
3494 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3495 using == rather than =. Huh... This fixes the dreaded problem
3496 wherein builtin_type_int becomes TYPE_CODE_FLT.
3498 * core.c (info_files): Show the inferior pid.
3500 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3501 already knows how to look in the source directory.
3503 * Remove psymtab hair from many places. Remove duplicated code
3504 for searching symbol tables. Hide psymtabs from most places.
3505 Make it fast to get from a psymtab to its symtab.
3507 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3508 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3509 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3510 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3511 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3512 new symtab completely. New psymtabs get symtab pointer
3513 initialized to zero. Remove MI warning printf.
3514 symtab.h: Comments. Add psymtab to symtab pointer.
3515 (PSYMTAB_TO_SYMTAB): New macro.
3516 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3517 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3519 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3521 (print_frame_info): Avoid special-casing symbols that have not yet
3524 * source.c (open_source_file): Quick path if we have already
3525 located the source file by its full name.
3527 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3528 find_pc_psymtab. When a name is found in the misc function
3529 vector, search the symbol table for its mangled name, not the
3530 name that the user typed.
3532 * bfd.h: Fix missing comment terminators, make #endifs match.
3534 * valarith.c (value_less): Handle unsigned int comparisons.
3535 Add FIXME about pointer compares, which assume host and target
3536 pointers are the same.
3538 * command.c (do_nothing_command): lint
3539 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3540 fix comments on debug symbol format for visibility. Actually set
3541 visibility of symbols.
3542 main.c (echo_command): lint; use <readline/history.h>.
3543 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3544 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3545 pointing past end of allocated memory; saber complains.
3546 obstack.h: Declare the external functions that we use.
3547 valarith.h: use <string.h>
3548 solib.c (solib_add): lint.
3550 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3552 * main.c (initialize_main): Default info_verbose to off, now that
3553 symbol reading is fast.
3554 (quit_command): Avoid clobbering exec_bfd while quitting.
3556 * Initial BFD (binary file diddling library) merger:
3557 coffread.c: Change AOUTHDR to struct exe_hdr.
3559 core.c: initialize initialized data at compile time.
3560 (core_file_command): Move from coredep.c, convert to bfd.
3561 (xfer_core_file): Convert to bfd.
3562 exec.c (exec_file_command): use bfd routines.
3564 mips-tdep.c: Remove exec_file_command and friends.
3567 * coredep.c: (fetch_core_registers) Convert core_file_command to
3568 fetch_core_registers.
3569 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3571 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3572 (my_bfd_read): More bogosity, which I don't think we call.
3573 (program_name): Remove this atrocity asap!
3575 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3578 values.c: allocate_repeat_value was not clearing the
3579 optimized_out field.
3580 (value_static_field): minor stylistic fix (wrong macro was used).
3581 valops.c (value_struct_elt_for_address): didn't work for C++
3584 * signame.c (_initialize_signame): Initialize signal names once.
3586 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3587 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3588 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3590 * remote-eb.c: Support user-settable baud rates on the serial port.
3592 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3594 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3596 * tconfig/sun3os4: Remove warning about native assembler,
3597 since it also occurs in the xconfig file.
3599 * findvar.c (registers): Allocate some slop after `registers'
3600 to prevent stray accesses from trashing the next variable.
3602 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3603 on the sun-3, by changing the #ifdef from `sun3' (which is not
3604 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3605 vars, which happened to follow `registers' in the executable.
3607 * readline/history.c (history_search): Heed gcc-2's advice
3608 and parenthesize && inside ||).
3610 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3611 tm-29k.c: Insert FSF copyright headers.
3613 * remote-eb.c: Better comments.
3615 * Makefile.dist: Update to 3.91.6.
3616 * TODO: note PREPARE_TO_STORE problem.
3618 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3620 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3622 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3624 * infrun.c (wait_for_inferior, at end): Don't set up
3625 prev_* if the inferior no longer exists.
3627 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3628 CANNOT_EXECUTE_STACK.
3629 valops.c (call_function): Use it.
3631 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3633 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3634 infrun.c (wait_for_inferior, 2 places): Use it.
3636 * values.c (value_being_returned): Only use
3637 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3639 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3640 right thing for remote-eb.c.
3642 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3643 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3645 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3646 (FRAME_FIND_SAVED_REGS).
3648 * findvar.c ({fetch,store}_registers): Check for
3649 REMOTE_{FETCH_STORE}_REGISTER macro.
3651 * findvar.c (get_saved_register): Add argument lval and
3652 change meaning of argument addr.
3653 findvar.c: Change calls to get_saved_register to reflect
3654 new calling convention.
3655 valops.c (value_assign): Use get_saved_register instead of
3656 find_saved_register.
3658 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3660 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3661 an (uninitialized) pointer to one. Use "&" when passing it
3664 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3666 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3669 * coffread.c (symbol_file_command): Put semicolon after
3671 Put safe_to_init_tdesc_context in #if defined (TDESC).
3672 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3673 coffread.c: #include <sys/stat.h>.
3674 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3675 Add missing ')' in check for "lc%" and friends. Remove
3677 Declare read_one_sym() at top of file.
3678 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3679 MC68WRMAGIC can have the same value without causing a duplicate
3682 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3684 * Allow a Makefile to be built without building the
3685 tm and xm file links that screw up builds in subdirectories.
3686 This is done with `config.gdb none', then you can do things
3687 like `make gdb.tar.Z'.
3688 * tconfig/none: Config file for no target system
3689 * xconfig/none: Config file for no host system
3690 * config.gdb: If no TM or XM files are called out by the
3691 host or target file, don't make links for them.
3693 * cplus-dem.c: Add documentation.
3695 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3696 simple error, so the user's gdb doesn't crash due to some object
3697 file problem (e.g. somebody is rebuilding the file out from under
3700 * printcmd.c (print_address_symbolic): demangle the symbol.
3702 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3703 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3704 (alldeps.mak): sort and uniq all results from this; duplicates
3705 hose gdb.tar.Z link building. Remove RCS files from
3706 tconfig and xconfig. Add config files for sun386. Add
3707 a few odd files to OTHERS and HFILES.
3709 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3711 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3712 Roll version number to 3.91.5. Make lint work in bindir.
3714 * README: Document cross-debugging and new file structure.
3716 * blockframe.c: Lint. Include "value.h" to declare read_register.
3717 (find_pc_partial_function): remove duplicate line.
3719 * command.h: Lint. Declare error_no_arg and dont_repeat.
3721 * tm-news.h: Remove inadvertently duplicated stuff.
3723 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3724 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3726 * config.gdb: Allow `config.gdb host target' form. Clean
3727 up previous change that printed bogus messages when you just said
3730 * core.c: #include "command.h" for lint.
3733 * main.c: Remove some casts of enums. Lint.
3740 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3742 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3743 read it from memory. This will allow us to save ptrace calls
3744 eventually. Changed caller single_step too.
3746 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3747 that we aren't going to use, saving many ptrace calls, especially
3748 when watchpointing or single stepping. Use some #define's for
3750 (store_inferior_registers): Ditto.
3751 (core_file_command): Use some #define's for constants.
3753 * tm-sparc.h: Add #define's for some register numbers, so we
3754 can eliminate the use of random constants in sparc-xdep.c.
3756 * stack.c (frame_command, print_frame_info, up_command,
3757 down_command) Remove frame_changed, since it
3758 causes a bug and doesn't seem to do anything useful. In some
3759 places it was used as a flag, in others as a stack level (?).
3761 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3762 default is to use the portable (vprintf) version rather than the
3764 * xm-news.h (MISSING_VPRINTF): Add.
3766 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3768 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3770 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3771 about linking debugged programs -Bstatic in the sun?os4 config
3772 files in tconfig and xconfig subdirectories.
3774 * main.c (main): Remove unreached exit(0) now that we exit
3777 * Create TODO file for online bug list. There are too many
3778 "little" bugs to keep track of on paper.
3780 * Change Projects file to refer to bug-gdb@cygnus.com
3781 rather than kingdon@ai.
3783 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3785 * Makefile.dist (VERSION): 3.91.4 now.
3787 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3788 (condense_misc_bunches): Add sanity check that misc_count is
3789 the same as the number of symbols in the bunch.
3791 * coffread.c: rename init_misc_bunches. Pass an argument
3792 to condense_misc_bunches (a zero).
3794 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3795 every time we are called; don't rely on our caller to do it.
3796 (add_file): Remove call to init_misc_bunches.
3798 * mipsread.c: Only warn, don't error, if unknown symbol types.
3799 This keeps an old gdb from falling on its face if it sees newly
3800 extended symbol info. Rename init_misc_bunches.
3802 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3804 * Merge in changes from Per Bothner for DECstations and other
3805 MIPS stuff. The rest is Bothner speaking:
3807 The next message is a merger of Alessando Forin's mips port with
3808 mine. I've tried to use my good if biased judgment to get
3809 the best of both. It *does* need testing.
3811 Some of the changes are general, *not* mips-specific.
3814 Didn't believe in little-endian bit order.
3815 There are still inconsistencies about whether flags
3816 like BITS_BIG_ENDIAN are integer (#if ...) or
3817 boolean (#ifdef ...). I tried to paper over them.
3819 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3820 Moved some misc_function code that was common to
3821 {dbx,coff,mips}read.c to symtab.c.
3822 In the process, I think I cleaned things up a bit.
3823 At the same time, moved obsavestring and obconcat to symtab.c.
3826 Removed obsolete condense_addl_misc_bunches (use
3827 condense_misc_bunches(1) instead).
3830 Needed to include <sys/dir>, at least on DECstations.
3832 valops.c, mips-tdep.c, tm-mips.h:
3833 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3834 conventions (when STACK_ALIGN is insufficient).
3835 Needed on mips, where doubles need 8-byte alignment,
3836 but ints only need 4.
3839 Removed cruft that was not being used.
3840 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3843 Print $ before register-names (I think that makes things a little
3845 Never print two instructions, even if one delays.
3846 Removed hex-disassemble set_cmd. (This is not mips-specific,
3847 so I think the argument is whether it is generally worthwhile or not.
3848 I'm inclined to think not, given how easy it is to
3849 convert between radixes in gdb.)
3852 This is basically Alessando's code.
3853 It doesn't use obstacks; I changed it to use obstacks
3854 in a few minor places where using malloc causes a
3855 memory leak. (Probably, more places could/should be changed.)
3856 I added record_misc_function where it was missing.
3857 In symbol_file_command and add_file_command, I tried
3858 to make the code consistent with more recent versions.
3859 Minor sylistic changes in parse_procedure.
3860 Make a .gdbinfo. psuedo-symbol point back to the real
3861 procedure symbol (using the isym field).
3864 This is basically from my port, but with a lot of details
3865 and a number of routines merged in from Alessando's version.
3866 I basically used my code "raw" backtrace (use heuristics
3867 from the actual code, rather than symbol table info) - though
3868 the idea is Alessandro's. I feel my code is a little cleaner
3869 here, particularly in being a little more flexible, such as being
3870 able to handle gcc-produced code (which it now can).
3871 It also doesn't do frame caching (which is not useful
3872 more recent gdb versions).
3873 I also used my code for push_/pop_dummy, more or less.
3874 I tried to incorporate AF's code for testing sigtramp
3875 while backtracing; I probably got it wrong.
3876 Added mips_print_register, which tries to scrunch as much
3877 information as possible on a screen...
3878 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3879 under mips-pinsn.c), I don't see anything mips-specific here,
3880 and I don't see it being all that useful anyway.
3883 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3884 Use more register names (rather than hard-cases numbers).
3886 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3888 * Hack up 3.90.11 changes:
3890 * Makefile.dist (depend): parameterize $(GCC).
3891 Add solib.c and solib.o.
3892 (readline): Fix vpath for both absolute or relative SRCDIR.
3894 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3895 Also, let the part I didn't understand at least compile so
3896 I can test the rest. FIXME.
3898 * dbxread.c: Fix thinko using strcmp.
3899 (init_psymbol_list): declare static.
3900 (partial_symbol_file_open): Comment cleanups better, avoid
3901 cleaning up the string table since the caller will do that.
3902 Move the stat for mod time into symbol_file_command, temporarily.
3903 (There should be a mod time for each symbol file, eventually,
3904 to control its rereading. FIXME.)
3906 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3907 SunOS, which gives error for shared libs otherwise. (From
3908 Schaefer, probably FIXME needs work for portability.)
3910 * solib.c: Move #include "param.h" to work.
3911 Lowercase all the Uppercase Letters In the Messages.
3912 (find_solib): Clean up inferior_so_name for debug printouts.
3913 Allow no argument, to mean all shared libraries.
3915 * symmisc.c: include param.h to get CLEAR_SOLIB.
3917 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3919 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
3920 to 3.90.11. ChangeLog entries below are from this.

3943 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3945 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.

3949 * Changes for Sun shared libraries:
3950 blockframe.c (find_pc_partial_function): If a non-text symbol
3951 is found, set *address = pc - FUNCTION_START_OFFSET.
3952 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
3953 Disable breakpoints instead of giving an error.
3954 source.c (select_source_symtab): Initialize cs_pst.
3955 symmisc.c: Call CLEAR_SOLIB if defined.
3956 symtab.h: Make text{low,high} CORE_ADDR not int.
3957 (psymtab): New field addr.
3959 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
3960 (record_misc_function): Give correct type for N_DATA symbols.
3961 (condense_misc_bunches): do "misc_function_count = j" regardless
3963 Take code which is shared between symbol_file_command and
3964 add_file_command and put it into partial_symbol_file_{open,read}.
3965 Split add_file_command into add_file_command and add_file.
3966 Make psymtab_to_symtab read in the string table if the file
3968 Two new parameters to read_dbx_symtab and start_psymtab.
3969 tm-sunos.h: New file.
3971 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3973 * infcmd.c: Change cont_command to continue_command and "cont"
3976 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3978 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
3980 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
3982 * values.c (USE_STRUCT_CONVENTION): Check for structures of
3983 size 1,2,4,8 rather than size < 8.
3985 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
3986 as necessary, not just once.
3988 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3990 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3992 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3994 * tm-news.h: Add CALL_DUMMY_*.
3996 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
3998 * config.gdb: In list_host, list_target, use ${i}, not $i.
4000 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4002 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
4004 * sparc-opcode.h: Change all store floating-point state register
4005 instructions to have the right match & lose fields.
4007 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4009 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
4011 config.gdb: If srcdir != ., create readline directory and
4012 copy a makefile into it.
4014 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
4015 consistency with POSIX.
4017 * breakpoint.c (bpstat_stop_status): Disable watchpoint
4018 when we exit its exp_valid_block.
4020 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
4022 * Makefile.dist: Bump version to 3.91.3.
4024 * Clean up handling of breakpoint commands (somewhat).
4025 Prompted by Tiemann bug report "cont 10" doesn't work any more.
4027 inferior.h: Add breakpoint_proceeded to inferior status struct
4028 and globals; save it and restore it.
4029 (clear_breakpoint_commands): Cleanup, remove old #define.
4031 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
4032 (save_inferior_status, restore_inferior_status): handle it also.
4033 (proceed): Remove earlier code that set breakpoint_proceeded.
4034 It is now set only in clear_proceed_status.
4035 (clear_proceed_status): Cleanup, use bpstat_clear rather
4036 than clear_breakpoint_commands. No callers need the stop_bpstat
4037 between clear_proceed_status and proceed.
4039 infcmd.c: Add breakpoint_proceeded definition and comment.
4040 (cont_command, jump_command, signal_command): Move call to
4041 clear_proceed_status right next to call to proceed.
4043 breakpoint.c (bpstat_do_actions): Avoid clobbering our
4044 caller's argument while running down the chain of breakpoints.
4045 Use new variable "breakpoint_proceeded" to determine when
4046 a command that it executes moves the inferior past the
4048 (bpstat_clear): Handle NULL argument.
4049 (bpstat_clear_actions): Avoid useless call to
4050 breakpoint_auto_delete.
4051 (delete_breakpoint): Clean up bpstat's that are pointing to
4052 the deleted breakpoint from the stop_bpstat chain.
4053 (breakpoint_auto_delete): Simplify.
4055 * Clean up handling of EOF, error on stdin, etc. This was
4056 prompted by a network problem that caused gdb to go into an
4057 infinite loop filling up its malloc'd memory.
4059 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
4060 not clear_breakpoints_commands, which is now gone.
4061 (main): If command_loop returns (e.g. from EOF on stdin), do
4062 a quit_command (looping back to command_loop if quit_command
4063 doesn't really quit).
4064 (command_loop): check result from command_line_input and
4065 exit if it returns NULL, rather than passing the NULL to
4067 (gdb_readline): Free malloc'd result space before returning
4070 * utils.c (query): Handle C-d to mean "yes", just as if the
4071 input was not a terminal. Also avoid infinite loop if EOF
4072 occurs in mid-input-line before newline. This allows
4073 query to be used at EOF on stdin with reasonable results.
4075 * infrun.c (proceed): Set breakpoint_proceeded.
4077 * values.c (value_as_long): Avoid infinite recursion for enums.
4078 (_initialize_values): Fix typo in help msg (kingdon).
4080 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
4081 RL_LIB for linking. This allows -lreadline for linking
4082 and nothing for dependencies, once readline is a real library.
4084 * config.gdb: Jim Kingdon: give useful error message if the
4085 host or target type is not recognized.
4087 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
4088 it just defines it. Dumb, but deal with it.
4090 * Jim Kingdon suggests:
4091 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
4093 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
4095 * Makefile.dist (VERSION): Bump version # to 3.91.2.
4097 * Clean up Bothner's changes.
4099 * blockframe.c (clear_pc_function_cache): New function.
4100 * blockframe.c: remake cache_pc_function_* static.
4101 * dbxread.c (symbol_file_command): remove references to
4102 cache_pc_function_* variables.
4103 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
4104 * printcmd.c: Avoid kludging a global variable (addressprint)
4105 to avoid printing the address of a string twice. Instead,
4106 pass the format letter 's' down low enough that it can be seen
4107 to avoid this problem.
4108 (print_formatted): Pass format arg to value_print.
4109 (restore_addressprint): Remove function.
4110 (do_examine): Avoid hacking addressprint, cleanups and such.
4111 (print_frame_args): Add a comment to a Bothner change.
4112 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
4113 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
4114 to wipe out the values cached in blockframe.c.
4115 * symtab.c (find_method): Add comment saying how big you must
4116 allocate to be "big enough". Per being terse again.
4117 * valprint.c (val_print): Handle format letter "s" to print
4118 strings without addresses. Add comment to vtbl printing code
4119 which casts with wild abandon. Rearrange reference-printing
4121 @0xaddr: value (print w/addressprint)
4122 value (print w/~addressprint)
4123 @0xaddr (parameter lists w/addressprint)
4124 or nothing (parameter lists w/o addressprint)
4126 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
4128 * Merge more changes from Per Bothner:
4130 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
4131 annoying) that I tried to improve it. Here are my suggestions.
4133 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
4136 Do automatic de-reference when taking the address of a reference.
4138 Don't deref_ref when printing parameter lists.
4140 More attempts at treating refernences properly.
4142 In val_print, if deref_ref==0, don't print dangling " = ".
4144 Add COERCE_REF macro, which de-references an REF.
4146 * Merge changes from Per Bothner:
4148 * Fixed (Sony news)-specific configuration problems.
4149 * Fixed other problems with using vanilla pcc and libc (enum problems;
4150 assumption that vsprintf exists).
4151 * Some major speed-ups (finc_pc_partial_function now caches a match;
4152 parsing avoids duplicate symbol_lookup calls).
4153 * Changed handling of baseclasses (no longer use baseclasses field
4154 of struct type, use the first n_baseclasses fields instead).
4155 * Various minor changes/fixes, most C++-related.
4158 Cache the most previous match from find_pc_partial_function.
4159 (Save both low and high ends of matching function's pc range.)
4160 This speeds up the loop of infrun.c:wait_for_inferior quite
4161 a bit, and makes step/next commands much zippier.
4163 Added an enum->int cast (otherwise, some compilers barf).
4165 No longer set baseclass offset to 0, since multiple
4166 inheritance now mostly works.
4167 Added a number of casts, to shut up compiler warnings
4168 (after stabs where made enums, not ints).
4169 When discarding a symbol table (in symbol_file_command),
4170 must clear the cache introduced in blockframe.c.
4171 Don't convert $vtbl_ptr_type to vtbl any more.
4172 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
4173 Mask off sign bit emitted by g++ for virtual table offset.
4174 Set voffset to -1 (not 1) for static member functions.
4176 Changed parsing/lexing of names to avoid doing symbol lookup twice
4177 (once when lexing to determine symbol class, once for real).
4178 Now only call symbol_lookup once. Fields of 'this' win especially big.
4180 Subpress printing addr twice in the case of 'x/s addr'.
4182 lookup_basetype_type is no longer used.
4183 Add find_methods as recursive helper function to decode_line_1.
4184 This allows multiple inheritance to work.
4185 Also, once one or more matches has been found, do not look in
4186 base-classes. (Baseclass methods would be overridden, anyway.)
4188 Removed baseclasses array in struct type.
4189 Instead of using baseclasses[i], use fields[i-1].
4190 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
4191 Changed sign convention of voffset (previous was inconsistent).
4193 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4195 Used to assume existence of vsprintf. Re-written to not need it
4196 if HAVE_VPRINTF is undefined.
4198 typecmp was too pessimistic. Made it less so.
4200 Don't print space after address.
4201 If vtable points to a misc symbol (with 0 offset), print it,
4202 since that indicates the actual class of the object.
4203 Changed ype_print_derivation_info to use new inheritance
4204 scheme (without baseclasses vector).
4206 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4207 Also, changes needed because TYPE_BASECLASSES were removed.
4209 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4211 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4214 If there is no path set, and the symbols don't indicate what directory
4215 a file was compiled in, look in the current directory. But either
4216 a path or a known compilation directory will prevent this.
4219 Three independent bug fixes:
4220 * Remove the #if 0 block that breaks some stuff.
4221 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4222 adapt gdb to either SunOS 4.0.* or 4.1.
4223 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4226 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4229 (type_print) Demangle the name being printed.
4230 (type_print_base) Handle botched demangling without coredump (tiemann).
4233 (check_stub_method): Document routine.
4234 (tiemann) fix bug for no-arg functions
4235 Avoid clobbering beyond end of malloc'd storage.
4236 Terminate the argument list properly.
4238 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4240 * Changes merged by John Gilmore:
4243 In breakpoint_1, use new print_address_symbolic instead
4244 of find_pc_partial_function. (This forces use of assembler-level
4245 addresses, and avoids misleading non-mangled source-level names.)
4247 Generalize ansi argument such that -1 means skip arglist totally.
4248 Removed global variable print_ansi_qualifiers (which made
4249 code non-reentrant), in favor of extra explicit arguments
4250 to internal routines.
4252 Add new helper function print_address_symbolic.
4253 Use find_pc_misc_function instead of find_pc_partial_function
4254 (since we want assembler-level symbols here).
4256 Print unknown function as just "f (...)", not "f (...) (...)".
4257 Use new fputs_demangled explicitly.
4259 Fixed a typing violation (problem: value.h cannot be imported
4260 without renaming many variable in this file).
4261 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4262 decode_line_1: Moved forward some never-reached code.
4263 Made decode_line_2 skip function prologues correctly.
4265 fputs_filtered should not demangle by default.
4266 Add new fputs_demangled to demangle on demand..
4268 Change value_struct_elt to use value_primitive_field (using recursive
4269 utility function search_struct_field). This allows foo.bar to work
4270 for multiple inheritance (so far only for data fields).
4271 Change check_field in the same way (recursive helper function
4272 to support multiple inheritance).
4273 (Note: there are more of these problems that I haven't fixed.
4274 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4275 value_of_this: 'this' symbol name is now just "this", note "$this".
4277 Don't print static members.
4278 Avoid printing "members of <type>" if there are none.
4279 Simplified type_print_derivation_info by merging duplicate code.
4280 Remove useless blank lines in type_print_base (ptype command).
4282 Added declaration of new routine value_primitive_field.
4284 Added value_primitive_field which is generalized version of
4285 value_field that can handle multiple inheritance (non-zero offsets etc).
4286 Re-implemented value_field to call value_primitive_field.
4288 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
4290 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4291 delete the whole environment. Karl Berry reported the bug.
4292 * source.c - fix openp to avoid //'s in filenames, which
4293 trigger an Emacs bug causing it to not be able to find files
4294 when running gdb in a window.
4295 * dbxread.c - zap the #if 0 that botches the add-file code.
4296 It seems to work a lot better without all the code commented out.
4298 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
4300 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
4303 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
4305 * Makefile - added a ${CFLAGS} to a couple of entries,
4306 added remote-sa.sparc.c
4307 * added remote.sa-sparc.c, a modification of remote.c
4308 which conducts a dialog directly with the SparcStation prom.
4309 * breakpoint.c, infrun.c, sparcdep.c added
4310 remote_insert_breakpoint(), and remote_remove_breakpoint()
4311 to breakpoint.c instead of directly writing breakpoint instructions.
4312 * sparcdep.c on remote_debugging,there is no need
4313 to remove signle step breakpoint instructions.
4314 * main.c added "-epoch" flag and "int epoch_interface" to main.c
4316 * printcmd.c - epoch interface sends lisp expressions to open up
4317 epoch windows on inspection.
4318 * valprint.c - added arrayprint, and addressprint and made adding
4319 format controls easier
4320 * wait.h added a couple of undef's because we were getting
4321 complaints about WSTOPSIG and WTERMSIG begin redefined.
4324 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
4326 * symtab.c (decode_line_1): Add support for handling method stubs
4327 in the type information.
4329 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
4331 * values.c (baseclass_addr): Run loop from INDEX+1 to
4332 N_BASECLASSES; otherwise, we can still get into a loop.
4333 @@ This should be restructured to use a cleaner search strategy.
4335 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
4337 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
4338 abbreviation "Tt" for tags which have the same name as their
4341 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
4343 * symtab.c (list_symbols): add ability to set breakpoints on all
4344 the functions which match a particular regular expression.
4346 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
4348 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
4349 should print ANSI qualifiers (such as `const' and `volatile').
4350 All callers changed to call with ANSI == 1, except from
4351 `check_method_stub', which uses old-style syntax.
4353 * symseg.h (struct fn_field): Remove unneccessary `args' field.
4354 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
4356 * values.c (check_stub_method): New function.
4358 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
4360 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
4361 * valprint (type_print_base): Ditto.
4363 * symtab.c (gdb_mangle_typename): New function.
4365 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
4367 * breakpoint.c (catch_command): New function. Provides a
4368 mechanism to set breakpoints based on catch clauses.
4369 (disable_catch): Similar, but disables breakpoints on catch
4371 (delete_catch): Similar, but deleted breakpoints on catch clauses.
4373 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
4375 * blockframe.c (blockvector_for_pc): New function.
4376 * blockframe.c (block_for_pc): Changed to call
4377 `blockvector_for_pc' and get the block itself.
4379 * stack.c (catch_info): New function. Prints info about
4380 exceptions which can be caught in the current frame.
4381 * stack.c (print_frame_label_vars): New function. Similar to
4382 `print_frame_local_vars'.
4383 * stack.c (print_block_frame_labels): Prints out labels that are
4384 defined in this frame. These labels are exceptions that can be
4387 * dbxread.c: Updated to handle N_CATCH symtab types.
4389 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
4391 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
4392 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
4393 when printing the type.
4395 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
4397 * valprint.c (val_print): Use `baseclass_addr' to access the
4398 baseclasses pointed to via the derived class object at VALADDR.
4400 * values.c (baseclass_addr): New function. Casts derived pointers
4401 to baseclass pointers taking virtual baseclasses and multiple
4402 inheritance into account.
4404 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4408 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4410 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
4411 exp_valid_block field correctly.
4413 * infrun.c (wait_for_inferior): When checking "don't even think
4414 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
4415 also check step_resume_breakpoint.
4416 Insert breakpoints and continue (not step) if
4417 step_resume_break_address != NULL, even if another_trap.
4418 If trap_expected and we enter sigtramp, then set up a
4420 If trap_expected is set when we hit the step_resume_break,
4422 When calling resume and trap_expected says tell resume to step
4423 (2 places), also check step_resume_break_address.
4425 * infrun.c (wait_for_inferior): Don't set
4426 prev_{pc,sp,func_{start,name}} before calling wait ().
4427 Do set them after exiting loop.
4428 Move their declarations outside functions.
4429 (start_inferior): Initialize them.
4431 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4433 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
4434 Restore old code which distinguishes between trap_expected and
4435 running_in_shell, just make the latter take any non-TRAP signal,
4438 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
4440 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
4441 xconfig/3b1 (CC,PINSN_CC): Define.
4443 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.

4451 infcmd.c (jump_command, read_pc), infrun.c (wait_for_inferior),
4452 printcmd.c (do_one_display): Use them.
4454 * utils.c: Split #ifdef USG into a USG_UTILS and a QUEUE_MISSING.
4455 xm-88k.h: Define USG_UTILS.
4457 Wed May 2 00:05:33 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4459 * printcmd.c (printf_command) [__INT_VARARGS_H]: New code.
4460 (printf_command): Add from_tty parameter.
4462 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
4464 * value.h: Add optimized_out field and change lazy field to
4465 char. Add macro VALUE_OPTIMIZED_OUT.
4467 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
4468 instead of stuffing things in buffers (oappend, etc).
4470 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
4471 execute_command, exit both loops.
4473 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
4475 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4477 * Makefile.dist (RAPP_OBS, rapp),
4478 rgdb.c, rserial.c, rudp.c, serial.c, udp.c, xdep.h,
4480 m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
4482 * valops.c (value_struct_elt), values.c (value_static_field):
4483 Change error messages to remove references to `info methods'.
4485 Tue Apr 24 10:25:10 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4488 infrun.c (start_inferior): Add START_INFERIOR_HOOK.
4489 infcmd.c [SHIFT_INST_REGS]: New code.
4490 findvar.c (read_relative_register_raw_bytes): Return a value.
4491 infcmd.c (do_registers_info): Check value from
4492 read_relative_register_raw_bytes.
4494 * command.c (delete_cmd): Free the struct cmd_list_element(s)
4497 Mon Apr 23 10:42:21 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4500 findvar.c (get_saved_register): New function.
4501 findvar.c: Rewrite code which called find_saved_register to
4502 call get_saved_register instead.
